If a different library is fine for you, you could try org.json:
JSONObject object = new JSONObject(myJSONString);
String[] keys = JSONObject.getNames(object);
for (String key : keys)
{
Object value = object.get(key);
// Determine type of value and do something with it...
}
I do not work with google android but I think you'll find it's not that hard to get this working. If you read the relevant bit of the java tutorial you'll see that a registered cookiehandler gets callbacks from the HTTP code.
So if there is no default (have you checked if CookieHandler.getDefault()
really is null?) then you can simply extend CookieHandler, implement put/get and make it work pretty much automatically. Be sure to consider concurrent access and the like if you go that route.
edit: Obviously you'd have to set an instance of your custom implementation as the default handler through CookieHandler.setDefault()
to receive the callbacks. Forgot to mention that.
Probably the best way is via the built-in struct module:
>>> import struct
>>> x = 1245427
>>> struct.pack('>BH', x >> 16, x & 0xFFFF)
'\x13\x00\xf3'
>>> struct.pack('>L', x)[1:] # could do it this way too
'\x13\x00\xf3'
Alternatively -- and I wouldn't usually recommend this, because it's mistake-prone -- you can do it "manually" by shifting and the chr()
function:
>>> x = 1245427
>>> chr((x >> 16) & 0xFF) + chr((x >> 8) & 0xFF) + chr(x & 0xFF)
'\x13\x00\xf3'
Out of curiosity, why do you only want three bytes? Usually you'd pack such an integer into a full 32 bits (a C unsigned long
), and use struct.pack('>L', 1245427)
but skip the [1:]
step?
My Personal View of Gist and GitHub:
Gist: Gist is a simple way to share code snippets and pastes with others. It is used when you need to share a sample piece of code or technique with your co-workers or friends.
And
GitHub GitHub, on the other hand, provides a platform to share an entire project as a repo among a team(private repo) or to the whole world(public repo).
Both Will log version details.
You can use Named Sections.
_Layout.cshtml

I think the problem you're running into is that, even though you can set your own umask values in the system, this does not allow you to explicitly control the default permissions set on a new file by gedit (or whatever editor you use).
I believe this detail is hard-coded into gedit and most other editors. Your options for changing it are (a) hacking up your own mod of gedit or (b) finding a text editor that allows you to set a preference for default permissions on new files. (Sorry, I know of none.)
In light of this, it's really not so bad to have to chmod your files, right?
SELECT INTO is typically used to generate temp tables or to copy another table (data and/or structure).
In day to day code you use INSERT because your tables should already exist to be read, UPDATEd, DELETEd, JOINed etc. Note: the INTO keyword is optional with INSERT
That is, applications won't normally create and drop tables as part of normal operations unless it is a temporary table for some scope limited and specific usage.
A table created by SELECT INTO will have no keys or indexes or constraints unlike a real, persisted, already existing table
The 2 aren't directly comparable because they have almost no overlap in usage
For people searching the equivalent in SwiftUI for Textfield
this is accentColor
:
TextField("Label", text: $self.textToBind).accentColor(Color.red)
To extend what Rahul Gupta said:
You can use Java function int random = Random.nextInt(n)
.
This returns a random int
in the range [0, n-1]
.
I.e., to get the range [20, 80]
use:
final int random = new Random().nextInt(61) + 20; // [0, 60] + 20 => [20, 80]
To generalize more:
final int min = 20;
final int max = 80;
final int random = new Random().nextInt((max - min) + 1) + min;
Stripes : pretty good. a book on this has come out from pragmatic programmers : http://www.pragprog.com/titles/fdstr/stripes. No XML. Requires java 1.5 or later.
tapestry : have tried an old version 3.x. I'm told that the current version 5.x is in Beta and pretty good.
Stripes should be the better in terms of taking care of maven, no xml and wrapping your head around fast.

In case anyone's interested, here's my solution to the problem. It works completely independently of the Draggable objects, by using events on the Droppable object instead. It works quite well:
$(function() {
$(".draggable").draggable({
opacity: .4,
create: function(){$(this).data('position',$(this).position())},
cursor:'move',
start:function(){$(this).stop(true,true)}
});
$('.active').droppable({
over: function(event, ui) {
$(ui.helper).unbind("mouseup");
},
drop:function(event, ui){
snapToMiddle(ui.draggable,$(this));
},
out:function(event, ui){
$(ui.helper).mouseup(function() {
snapToStart(ui.draggable,$(this));
});
}
});
});
function snapToMiddle(dragger, target){
var topMove = target.position().top - dragger.data('position').top + (target.outerHeight(true) - dragger.outerHeight(true)) / 2;
var leftMove= target.position().left - dragger.data('position').left + (target.outerWidth(true) - dragger.outerWidth(true)) / 2;
dragger.animate({top:topMove,left:leftMove},{duration:600,easing:'easeOutBack'});
}
function snapToStart(dragger, target){
dragger.animate({top:0,left:0},{duration:600,easing:'easeOutBack'});
}
You can specify JsonSerializerSettings
for each JsonConvert
, and you can set a global default.
Single JsonConvert
with an overload:
// Option #1.
JsonSerializerSettings config = new JsonSerializerSettings { ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore };
this.json = JsonConvert.SerializeObject(YourObject, Formatting.Indented, config);
// Option #2 (inline).
JsonConvert.SerializeObject(YourObject, Formatting.Indented,
new JsonSerializerSettings() {
ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
}
);
Global Setting with code in Application_Start()
in Global.asax.cs:
JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
Formatting = Newtonsoft.Json.Formatting.Indented,
ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
};

The children of a row-flexbox container automatically fill the container's vertical space.
Specify flex: 1;
for a child if you want it to fill the remaining horizontal space:

I stumbled upon a situation where I have a small component I want to reuse, and added some code in a reusable view itself(it's really not much more than a button that opens a PopoverController
).
While this works fine in the iPad (the UIPopoverController
presents itself, therefor needs no reference to a UIViewController
), getting the same code to work means suddenly referencing your presentViewController
from your UIViewController
. Kinda inconsistent right?
Like mentioned before, it's not the best approach to have logic in your UIView. But it felt really useless to wrap the few lines of code needed in a separate controller.
Either way, here's a swift solution, which adds a new property to any UIView:
extension UIView {
var viewController: UIViewController? {
var responder: UIResponder? = self
while responder != nil {
if let responder = responder as? UIViewController {
return responder
}
responder = responder?.nextResponder()
}
return nil
}
}
As mentioned, GitHub API returns downloads count of binary file releases. I developed a little script to easly get downloads count by command line.

To run an executable in mac
1). Move to the path of the file:
cd/PATH_OF_THE_FILE
2). Run the following command to set the file's executable bit using the chmod command:
chmod +x ./NAME_OF_THE_FILE
3). Run the following command to execute the file:
./NAME_OF_THE_FILE
Once you have run these commands, going ahead you just have to run command 3, while in the files path.
If anaconda is fully updated, a simple "conda init zsh" should work. Navigate into the anaconda3 folder using
cd /path/to/anaconda3/
of course replacing "/path/to/anaconda/" with "~/anaconda3" or "/anaconda3" or wherever the "anaconda3" folder is kept.
To make sure it's updated, run
./bin/conda update --prefix . anaconda
After this, running
./bin/conda init zsh
(or whatever shell you're using) will finish the job cleanly.
Here's a way to do it without using groups (Python 3.6 or above):
>>> re.search('2\d\d\d[01]\d[0-3]\d', 'report_20191207.xml')[0]
'20191207'
There is only one PNG format, but it supports 5 color types.
PNG-8 refers to palette variant, which supports only 256 colors, but is usually smaller in size. PNG-8 can be a GIF substitute.
PNG-24 refers to true color variant, which supports more colors, but might be bigger. PNG-24 can be used instead of JPEG, if lossless image format is needed.
Any modern web browser will support both variants.
You can compile with either Cygwin's g++
or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll
(and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin
to the end of your Windows system PATH
variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
for (int i = 1; i*i <= num; ++i)
{
if (num % i == 0)
cout << i << endl;
if (num/i!=i)
cout << num/i << endl;
}
As an alternative to Regex, running:
Sub Replacer()
Dim N As Long, i As Long
N = Cells(Rows.Count, "A").End(xlUp).Row
For i = 1 To N
If Left(Cells(i, "A").Value, 9) = "texts are" Then
Cells(i, "A").Value = "texts are replaced"
End If
Next i
End Sub
will produce:

The main concept of partial view is returning the HTML code rather than going to the partial view it self.
[HttpGet]
public ActionResult Calendar(int year)
{
var dates = new List<DateTime>() { /* values based on year */ };
HolidayViewModel model = new HolidayViewModel {
Dates = dates
};
return PartialView("HolidayPartialView", model);
}
this action return the HTML code of the partial view ("HolidayPartialView").
To refresh partial view replace the existing item with the new filtered item using the jQuery below.
$.ajax({
url: "/Holiday/Calendar",
type: "GET",
data: { year: ((val * 1) + 1) }
})
.done(function(partialViewResult) {
$("#refTable").html(partialViewResult);
});
That should do the trick for the newest MySQL versions:
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE DB = "elstream_development";
You have two options:
1) Using String.valueOf() method:
int sdRate=5;
text_Rate.setText(String.valueOf(sdRate)); //faster!, recommended! :)
2) adding an empty string:
int sdRate=5;
text_Rate.setText("" + sdRate));
Casting is not an option, will throw a ClassCastException
int sdRate=5;
text_Rate.setText(String.valueOf((String)sdRate)); //EXCEPTION!
var result = (35.8 / 100) * 10000;
(Thank you jball for this change of order of operations. I didn't consider it).
Below code runs correctly.
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double num1 = 3.12345678;
cout << fixed << showpoint;
cout << setprecision(2);
cout << num1 << endl;
}
With ES6 you can simply do:
for(const element of Results) {
element.Active = "false";
}
There are two problems in your code:
visibility
and not visiblity
..style
property.It's easy to fix. Simple replace this:
document.getElementById("remember").visiblity
with this:
document.getElementById("remember").style.visibility
using (var connection = new SqlConnection("Enter Your Connection String"))
{
connection.Open();
using (var command = connection.CreateCommand())
{
command.CommandText = "Enter the First Command Here";
command.ExecuteNonQuery();
command.CommandText = "Enter Second Comand Here";
command.ExecuteNonQuery();
//Similarly You can Add Multiple
}
}
To piggyback on @niutech's answer, you can make a very simple bookmark snippet.
Using Chrome, though it works similarly with other browsers
javascript:top.location="http://htmlpreview.github.com/?"+document.URL
select DATEDIFF(dd, '12/30/1899', mydatefield)
Expanded(
child: Align(
alignment: FractionalOffset.bottomCenter,
child: Padding(
padding: EdgeInsets.only(bottom: 10.0),
child: //Your widget here,
),
),
),
For the first one: your program will go through the loop once for every row in the result set returned by the query. You can know in advance how many results there are by using mysql_num_rows()
.
For the second one: this time you are only using one row of the result set and you are doing something for each of the columns. That's what the foreach
language construct does: it goes through the body of the loop for each entry in the array $row
. The number of times the program will go through the loop is knowable in advance: it will go through once for every column in the result set (which presumably you know, but if you need to determine it you can use count($row)
).

Usually the desire is to match the menu width to the width of the dropdown parent. This can be achieved easily like so:
.dropdown-menu {
width:100%;
}
lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")...]
msg = filter(lambda x : x != "8", lst)
print msg
EDIT: For anyone who came across this post, just for understanding the above removes any elements from the list which are equal to 8.
Supposing we use the above example the first element ("aaaaa8") would not be equal to 8 and so it would be dropped.
To make this (kinda work?) with how the intent of the question was we could perform something similar to this
msg = filter(lambda x: x != "8", map(lambda y: list(y), lst))
What this does is split each element of list up into an array of characters so ("aaaa8") would become ["a", "a", "a", "a", "8"].
This would result in a data type that looks like this
msg = [["a", "a", "a", "a"], ["b", "b"]...]
So finally to wrap that up we would have to map it to bring them all back into the same type roughly
msg = list(map(lambda q: ''.join(q), filter(lambda x: x != "8", map(lambda y: list(y[0]), lst))))
I would absolutely not recommend it, but if you were really wanting to play with map and filter, that would be how I think you could do it with a single line.
You can use the "-r" option to set the sender address:
mailx -r [email protected] -s ...
Your fundamental problem is that grep
works one line at a time - so it cannot find a SELECT statement spread across lines.
Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.
I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.
In outline, for a single file:
$/ = "\n\n"; # Paragraphs
while (<>)
{
if ($_ =~ m/SELECT.*customerName.*FROM/mi)
{
printf file name
go to next file
}
}
That needs to be wrapped into a sub that is then invoked by the methods of File::Find.
update:
as @Andy mentioned below Google has created HtmlCompat
which can be used instead of the method below. Add this dependency implementation 'androidx.core:core:1.0.1
to the build.gradle file of your app. Make sure you use the latest version of androidx.core:core
.
This allows you to use:
HtmlCompat.fromHtml(html, HtmlCompat.FROM_HTML_MODE_LEGACY);
You can read more about the different flags on the HtmlCompat-documentation
original answer:
In Android N they introduced a new Html.fromHtml
method. Html.fromHtml
now requires an additional parameter, named flags. This flag gives you more control about how your HTML gets displayed.
On Android N and above you should use this new method. The older method is deprecated and may be removed in the future Android versions.
You can create your own Util-method which will use the old method on older versions and the newer method on Android N and above. If you don't add a version check your app will break on lower Android versions. You can use this method in your Util class.
@SuppressWarnings("deprecation")
public static Spanned fromHtml(String html){
if(html == null){
// return an empty spannable if the html is null
return new SpannableString("");
}else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
// FROM_HTML_MODE_LEGACY is the behaviour that was used for versions below android N
// we are using this flag to give a consistent behaviour
return Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY);
} else {
return Html.fromHtml(html);
}
}
You can convert the HTML.FROM_HTML_MODE_LEGACY
into an additional parameter if you want. This gives you more control about it which flag to use.
You can read more about the different flags on the Html class documentation
var dn = await Task.WhenAll<dynamic>(FeedCat(),SellHouse(),BuyCar());
if you want to access Cat, you do this:
var ct = (Cat)dn[0];
This is very simple to do and very useful to use, there is no need to go after a complex solution.
Something is wrong with your Python/Computer.
a = iter(list(range(10)))
for i in a:
print(i)
next(a)
>>>
0
2
4
6
8
Works like expected.
Tested in Python 2.7 and in Python 3+ . Works properly in both
If you are using a database that supports map-reduce, like couchdb, storing tags in a plain text field or list field is indeed the best way. Example:
tagcloud: {
map: function(doc){
for(tag in doc.tags){
emit(doc.tags[tag],1)
}
}
reduce: function(keys,values){
return values.length
}
}
Running this with group=true will group the results by tag name, and even return a count of the number of times that tag was encountered. It's very similar to counting the occurrences of a word in text.
The 1. usecase which comes into my mind, is an api
call, which should't go into the render, because it will run for each
state change. And the API call should be only performed on special state change, and not on every render.
changeSearchParams = (params) => {
this.setState({ params }, this.performSearch)
}
performSearch = () => {
API.search(this.state.params, (result) => {
this.setState({ result })
});
}
Hence for any state change, an action can be performed in the render methods body.
Very bad practice, because the render
-method should be pure, it means no actions, state changes, api calls, should be performed, just composite your view and return it. Actions should be performed on some events only. Render is not an event, but componentDidMount
for example.
I found this perfect solution and may useful, You can directly get in format as you want:
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -90); // I just want date before 90 days. you can give that you want.
SimpleDateFormat s = new SimpleDateFormat("yyyy-MM-dd"); // you can specify your format here...
Log.d("DATE","Date before 90 Days: " + s.format(new Date(cal.getTimeInMillis())));
Thanks.
How does spark context in your application pick the value for spark master?
SparkConf
while creating SC.System.getProperties
(where SparkSubmit earlier put it after reading your --master
argument).Now, SparkSubmit
runs on the driver -- which in your case is the machine from where you're executing the spark-submit
script. And this is probably working as expected for you too.
However, from the information you've posted it looks like you are creating a spark context in the code that is sent to the executor -- and given that there is no spark.master
system property available there, it fails. (And you shouldn't really be doing so, if this is the case.)
Can you please post the GroupEvolutionES
code (specifically where you're creating SparkContext(s)
).
Another solution to avoid inserting html into data-title is to create independant div with tooltip html content, and refer to this div when creating your tooltip :
<!-- Tooltip link -->
<p><span class="tip" data-tip="my-tip">Hello world</span></p>
<!-- Tooltip content -->
<div id="my-tip" class="tip-content hidden">
<h2>Tip title</h2>
<p>This is my tip content</p>
</div>
<script type="text/javascript">
$(document).ready(function () {
// Tooltips
$('.tip').each(function () {
$(this).tooltip(
{
html: true,
title: $('#' + $(this).data('tip')).html()
});
});
});
</script>
This way you can create complex readable html content, and activate as many tooltips as you want.

I used all the above answers and it was giving me errors so I tried
adb shell monkey -p com.yourpackage.name -c android.intent.category.LAUNCHER 1
and it worked. One advantage is you dont have to specify your launcher activity if you use this command.
In the ActionListener Class you can simply add
public void actionPerformed(ActionEvent event) {
if (event.getSource()==textField){
textButton.doClick();
}
else if (event.getSource()==textButton) {
//do something
}
}
I know this is like years old post but since there is no selected answer I hope this answer may give you what you are expecting...
if(document.getElementsByTagName){
var table = document.getElementById('table className');
for (var i = 0, row; row = table.rows[i]; i++) {
//rows would be accessed using the "row" variable assigned in the for loop
for (var j = 0, col; col = row.cells[j]; j++) {
//columns would be accessed using the "col" variable assigned in the for loop
alert('col html>>'+col.innerHTML); //Will give you the html content of the td
alert('col>>'+col.innerText); //Will give you the td value
}
}
}

The mktemp(1)
man page explains it fairly well:
Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win. A safer, though still inferior, approach is to make a temporary directory using the same naming scheme. While this does allow one to guarantee that a temporary file will not be subverted, it still allows a simple denial of service attack. For these reasons it is suggested that mktemp be used instead.
In a script, I invoke mktemp something like
mydir=$(mktemp -d "${TMPDIR:-/tmp/}$(basename $0).XXXXXXXXXXXX")
which creates a temporary directory I can work in, and in which I can safely name the actual files something readable and useful.
mktemp
is not standard, but it does exist on many platforms. The "X"s will generally get converted into some randomness, and more will probably be more random; however, some systems (busybox ash, for one) limit this randomness more significantly than others
By the way, safe creation of temporary files is important for more than just shell scripting. That's why python has tempfile, perl has File::Temp, ruby has Tempfile, etc…
I had this error when I was trying to plot high dimensional data. If that's what is going on with you, try multidimensional scaling: http://www.statmethods.net/advstats/mds.html
In my case I was using a UIWebView and I passed a NSString in the second parameter instead of a NSURL. So I suspect that wrong class types passed to a functions can cause this error.
You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.
Just do the following for executing a POST request:
var requestify = require('requestify');
requestify.post('http://example.com', {
hello: 'world'
})
.then(function(response) {
// Get the response body (JSON parsed or jQuery object for XMLs)
response.getBody();
});
The header <math.h>
is a C std lib header. It defines a lot of stuff in the global namespace. The header <cmath>
is the C++ version of that header. It defines essentially the same stuff in namespace std
. (There are some differences, like that the C++ version comes with overloads of some functions, but that doesn't matter.) The header <cmath.h>
doesn't exist.
Since vendors don't want to maintain two versions of what is essentially the same header, they came up with different possibilities to have only one of them behind the scenes. Often, that's the C header (since a C++ compiler is able to parse that, while the opposite won't work), and the C++ header just includes that and pulls everything into namespace std
. Or there's some macro magic for parsing the same header with or without namespace std
wrapped around it or not. To this add that in some environments it's awkward if headers don't have a file extension (like editors failing to highlight the code etc.). So some vendors would have <cmath>
be a one-liner including some other header with a .h
extension. Or some would map all includes matching <cblah>
to <blah.h>
(which, through macro magic, becomes the C++ header when __cplusplus
is defined, and otherwise becomes the C header) or <cblah.h>
or whatever.
That's the reason why on some platforms including things like <cmath.h>
, which ought not to exist, will initially succeed, although it might make the compiler fail spectacularly later on.
I have no idea which std lib implementation you use. I suppose it's the one that comes with GCC, but this I don't know, so I cannot explain exactly what happened in your case. But it's certainly a mix of one of the above vendor-specific hacks and you including a header you ought not to have included yourself. Maybe it's the one where <cmath>
maps to <cmath.h>
with a specific (set of) macro(s) which you hadn't defined, so that you ended up with both definitions.
Note, however, that this code still ought not to compile:
#include <cmath>
double f(double d)
{
return abs(d);
}
There shouldn't be an abs()
in the global namespace (it's std::abs()
). However, as per the above described implementation tricks, there might well be. Porting such code later (or just trying to compile it with your vendor's next version which doesn't allow this) can be very tedious, so you should keep an eye on this.
Since the border is used just for visual appearance, you could put it into the ListBoxItem's ControlTemplate and modify the properties there. In the ItemTemplate, you could place only the StackPanel and the TextBlock. In this way, the code also remains clean, as in the appearance of the control will be controlled via the ControlTemplate and the data to be shown will be controlled via the DataTemplate.
You can use json.loads
:
import json
import requests
response = requests.get(...)
json_data = json.loads(response.text)
This converts a given string into a dictionary which allows you to access your JSON data easily within your code.
Or you can use @Martijn's helpful suggestion, and the higher voted answer, response.json()
.
Perhaps I am misunderstanding the question, by why exactly would you not want to use atoi? I see no point in reinventing the wheel.
Am I just missing the point here?

In my case I had to kill a hanging MSBuild.exe
process that was locking the file (it was there even after I closed Visual Studio).
As pointed out by others, increasing the limit is not the best answer. I was facing the same issue, but in my code I was nowhere using any event listener. When I closely looked into the code, I was creating a lot of promises at times. Each promise had some code of scraping the provided URL (using some third-party library). If you are doing something like that, then it may be the cause.
Refer this thread on how to prevent that: What is the best way to limit concurrency when using ES6's Promise.all()?

I meet the same questions in 3.7 on ubuntu 12.04. My Os use a proxy 127.0.0.1,and the eclipse use another proxy 192.168.1.1.
I read the .log for info. It says !MESSAGE System property http.proxyHost is set to 127.0.0.1 but should be 192.168.1.1.
so I change the eclipse net work setting to the same as the system . At last,it works.
You could simply use Runtime.exec()
Firstly there is an extra }
after every array object
.
Secondly "geodata" is a JSONArray
. So instead of JSONObject geoObject = jObject.getJSONObject("geodata");
you have to get it as JSONArray geoObject = jObject.getJSONArray("geodata");
Once you have the JSONArray
you can fetch each entry in the JSONArray
using geoObject.get(<index>)
.

}
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())

I found it hard to decipher what is meant by "working directory of the VM". In my example, I was using the Java Service Wrapper program to execute a jar - the dump files were created in the directory where I had placed the wrapper program, e.g. c:\myapp\bin. The reason I discovered this is because the files can be quite large and they filled up the hard drive before I discovered their location.

<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>

</TextBlock>
</DataTemplate>

The main idea is to bind the width of the cellTemplete element to the width of the ViewGridColumn. Width=100 is default width used until first resize. There isn't any code behind. Everything is in xaml.

You can use length
:
if($("#one").length) { // 0 == false; >0 == true
alert('yes');
}
You can use following :

#p1{
font-weight: bold;
}
OR
<Strong><p>Some text here </p></strong>
OR
You can use <h1> tag

I also had the same problem. I use "Postman" for JSON request. The code itself is not wrong. I simply set the content type to JSON (application/json
) and it worked, as you can see on the image below
On my machine I tried check it. My result:
Calendar.getInstance().getTime() (*1000000 times) = 402ms new Date().getTime(); (*1000000 times) = 18ms System.currentTimeMillis() (*1000000 times) = 16ms
Don't forget about GC (if you use Calendar.getInstance()
or new Date()
)

Charlie Collins gave me a perfect answer using the Application.class
. I was not aware that we could subclass it that easily. Here is a simplified example using a custom application class.
AndroidManifest.xml
Give the android:name
attribute to use your own application class.
...
<application android:name="MyApplication"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
....
MyApplication.java
Use this as a global reference holder. It works fine within a same process.
public class MyApplication extends Application {
private MainActivity mainActivity;
@Override
public void onCreate() {
super.onCreate();
}
public void setMainActivity(MainActivity activity) { this.mainActivity=activity; }
public MainActivity getMainActivity() { return mainActivity; }
}
MainActivity.java
Set the global "singleton" reference to the application instance.
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
((MyApplication)getApplication()).setMainActivity(this);
}
...
}
MyPreferences.java
A simple example where I use a main activity from another activity instance.
public class MyPreferences extends PreferenceActivity
implements SharedPreferences.OnSharedPreferenceChangeListener {
@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
PreferenceManager.getDefaultSharedPreferences(this)
.registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
if (!key.equals("autostart")) {
((MyApplication)getApplication()).getMainActivity().refreshUI();
}
}
}
In addition to the recommendations, I also had to rm -Rf .git/modules/path/to/submodule
to be able to add a new submodule with the same name (in my case I was replacing a fork with the original)
The answer is: for no good reason whatsoever.
Contrary to its name, the XmlSerializer
class is used not only for serialization, but also for deserialization. It performs certain checks on your class to make sure that it will work, and some of those checks are only pertinent to deserialization, but it performs them all anyway, because it does not know what you intend to do later on.
The check that your class fails to pass is one of the checks that are only pertinent to deserialization. Here is what happens:
During deserialization, the XmlSerializer
class will need to create
instances of your type.
In order to create an instance of a type, a constructor of that type needs to be invoked.
If you did not declare a constructor, the compiler has already supplied a default parameterless constructor, but if you did declare a constructor, then that's the only constructor available.
So, if the constructor that you declared accepts parameters, then the only way to instantiate your class is by invoking that constructor which accepts parameters.
However, XmlSerializer
is not capable of invoking any constructor
except a parameterless constructor, because it does not know what
parameters to pass to constructors that accept parameters. So, it checks to see if your class has a parameterless constructor, and since it does not, it fails.
So, if the XmlSerializer
class had been written in such a way as to only perform the checks pertinent to serialization, then your class would pass, because there is absolutely nothing about serialization that makes it necessary to have a parameterless constructor.
As others have already pointed out, the quick solution to your problem is to simply add a parameterless constructor. Unfortunately, it is also a dirty solution, because it means that you cannot have any readonly
members initialized from constructor parameters.
In addition to all this, the XmlSerializer
class could have been written in such a way as to allow even deserialization of classes without parameterless constructors. All it would take would be to make use of "The Factory Method Design Pattern" (Wikipedia). From the looks of it, Microsoft decided that this design pattern is far too advanced for DotNet programmers, who apparently should not be unnecessarily confused with such things. So, DotNet programmers should better stick to parameterless constructors, according to Microsoft.

You should look into XPath. Once you start using it, you'll find its a lot more efficient and easier to code than iterating through lists. It also lets you directly get the things you want.
Then the code would be something similar to
string attrVal = doc.SelectSingleNode("/MyConfiguration/@SuperNumber").Value;
Note that XPath 3.0 became a W3C Recommendation on April 8, 2014.
You would do that by providing a fully qualified name, e.g.:
SELECT tbl_names.id as id, name, section FROM tbl_names, tbl_section WHERE tbl_names.id = tbl_section.id
Which would give you the id of tbl_names

There is no easy way to do this. I needed this as well, but wanted a function that can take any two variables and test for equality. That includes non-object values, objects, arrays and any level of nesting.
In your question, you mention wanting to ignore the order of the values in an array. My solution doesn't inherently do that, but you can achieve it by sorting the arrays before comparing for equality
I also wanted the option of casting non-objects to strings so that [1,2]===["1",2]
Since my project uses UnderscoreJs, I decided to make it a mixin rather than a standalone function.
You can test it out on http://jsfiddle.net/nemesarial/T44W4/
Here is my mxin:
_.mixin({
/**
Tests for the equality of two variables
valA: first variable
valB: second variable
stringifyStatics: cast non-objects to string so that "1"===1
**/
equal:function(valA,valB,stringifyStatics){
stringifyStatics=!!stringifyStatics;
//check for same type
if(typeof(valA)!==typeof(valB)){
if((_.isObject(valA) || _.isObject(valB))){
return false;
}
}
//test non-objects for equality
if(!_.isObject(valA)){
if(stringifyStatics){
var valAs=''+valA;
var valBs=''+valB;
ret=(''+valA)===(''+valB);
}else{
ret=valA===valB;
}
return ret;
}
//test for length
if(_.size(valA)!=_.size(valB)){
return false;
}
//test for arrays first
var isArr=_.isArray(valA);
//test whether both are array or both object
if(isArr!==_.isArray(valB)){
return false;
}
var ret=true;
if(isArr){
//do test for arrays
_.each(valA,function(val,idx,lst){
if(!ret){return;}
ret=ret && _.equal(val,valB[idx],stringifyStatics);
});
}else{
//do test for objects
_.each(valA,function(val,idx,lst){
if(!ret){return;}
//test for object member exists
if(!_.has(valB,idx)){
ret=false;
return;
}
// test for member equality
ret=ret && _.equal(val,valB[idx],stringifyStatics);
});
}
return ret;
}
});
This is how you use it:
_.equal([1,2,3],[1,2,"3"],true)
To demonstrate nesting, you can do this:
_.equal(
['a',{b:'b',c:[{'someId':1},2]},[1,2,3]],
['a',{b:'b',c:[{'someId':"1"},2]},["1",'2',3]]
,true);
Let me describe the JS solution as a separate answer:
function handleResize()
{
var mapElement = document.getElementById("map");
mapElement.style.height = (mapElement.offsetWidth * 1.72) + "px";
}
<div id="map" onresize="handleResize()">...</div>
(or register the event listener dynamically).
mapElement.style.width * 1.72
will not work, since it requires that the width be set explicitly on the element, either using the width
DOM attribute or in the inline style's width
CSS property.
WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT
in wp-config.php
:
define( 'WP_MAX_MEMORY_LIMIT' , '512M' );
I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.
EDIT 7/1/15:
I wrote this answer a pretty long time ago and haven't been keeping up a lot with angular for a while, but it seems as though this answer is still relatively popular, so I wanted to point out that a couple of the point @nicolas makes below are good. For one, injecting $rootScope and attaching the helpers there will keep you from having to add them for every controller. Also - I agree that if what you're adding should be thought of as Angular services OR filters, they should be adopted into the code in that manner.
Also, as of the current version 1.4.2, Angular exposes a "Provider" API, which is allowed to be injected into config blocks. See these resources for more:
https://docs.angularjs.org/guide/module#module-loading-dependencies
AngularJS dependency injection of value inside of module.config
I don't think I'm going to update the actual code blocks below, because I'm not really actively using Angular these days and I don't really want to hazard a new answer without feeling comfortable that it's actually conforming to new best practices. If someone else feels up to it, by all means go for it.
EDIT 2/3/14:
After thinking about this and reading some of the other answers, I actually think I prefer a variation of the method brought up by @Brent Washburne and @Amogh Talpallikar. Especially if you're looking for utilities like isNotString() or similar. One of the clear advantages here is that you can re-use them outside of your angular code and you can use them inside of your config function (which you can't do with services).
That being said, if you're looking for a generic way to re-use what should properly be services, the old answer I think is still a good one.
What I would do now is:
app.js:
var MyNamespace = MyNamespace || {};
MyNamespace.helpers = {
isNotString: function(str) {
return (typeof str !== "string");
}
};
angular.module('app', ['app.controllers', 'app.services']).
config(['$routeProvider', function($routeProvider) {
// Routing stuff here...
}]);
controller.js:
angular.module('app.controllers', []).
controller('firstCtrl', ['$scope', function($scope) {
$scope.helpers = MyNamespace.helpers;
});
Then in your partial you can use:
<button data-ng-click="console.log(helpers.isNotString('this is a string'))">Log String Test</button>
Old answer below:
It might be best to include them as a service. If you're going to re-use them across multiple controllers, including them as a service will keep you from having to repeat code.
If you'd like to use the service functions in your html partial, then you should add them to that controller's scope:
$scope.doSomething = ServiceName.functionName;
Then in your partial you can use:
<button data-ng-click="doSomething()">Do Something</button>
Here's a way you might keep this all organized and free from too much hassle:
Separate your controller, service and routing code/config into three files: controllers.js, services.js, and app.js. The top layer module is "app", which has app.controllers and app.services as dependencies. Then app.controllers and app.services can be declared as modules in their own files. This organizational structure is just taken from Angular Seed:
app.js:
angular.module('app', ['app.controllers', 'app.services']).
config(['$routeProvider', function($routeProvider) {
// Routing stuff here...
}]);
services.js:
/* Generic Services */
angular.module('app.services', [])
.factory("genericServices", function() {
return {
doSomething: function() {
//Do something here
},
doSomethingElse: function() {
//Do something else here
}
});
controller.js:
angular.module('app.controllers', []).
controller('firstCtrl', ['$scope', 'genericServices', function($scope, genericServices) {
$scope.genericServices = genericServices;
});
Then in your partial you can use:
<button data-ng-click="genericServices.doSomething()">Do Something</button>
<button data-ng-click="genericServices.doSomethingElse()">Do Something Else</button>
That way you only add one line of code to each controller and are able to access any of the services functions wherever that scope is accessible.
This really depends on what exactly you're trying to accomplish.
The System.ComponentModel.TypeDescriptor stuff can be used to add attributes to types, properties and object instances, and it has the limitation that you have to use it to retrieve those properties as well. If you're writing the code that consumes those attributes, and you can live within those limitations, then I'd definitely suggest it.
As far as I know, the PropertyGrid control and the visual studio design surface are the only things in the BCL that consume the TypeDescriptor stuff. In fact, that's how they do about half the things they really need to do.
Sorry, if this is irelevant, but will return list with matches using FindAll() in case you need this:
private bool IsContain(string cont)
{
List<string> ListToMatch= new List<string>() {"string1","string2"};
if (ListToMatch.ToArray().Any(cont.Contains))
{
return false;
}
else
return true;
}
And usage:
List<string> ListToCheck = new List<string>() {"string1","string2","string3","string4"};
List<string> FinalList = ListToCheck.FindAll(IsContain);
The final list contains only the matched elements string1 and string2 from list to check. Can easy be switched to int List.
One can simply use java.bean.ConstructorProperties annotation - it's much less verbose and Jackson also accepts it. For example :
import java.beans.ConstructorProperties;
@ConstructorProperties({"answer","closed","language","interface","operation"})
public DialogueOutput(String answer, boolean closed, String language, String anInterface, String operation) {
this.answer = answer;
this.closed = closed;
this.language = language;
this.anInterface = anInterface;
this.operation = operation;
}
A single regular expression replace should do it:
var stringWithSmallIntegers = "4° 7' 34"W, 168° 1' 23"N";
var paddedString = stringWithSmallIntegers.replace(
/\d+/g,
function pad(digits) {
return digits.length === 1 ? '0' + digits : digits;
});
alert(paddedString);
shows the expected output.
Consider this:
file a.txt:
abcd
efgh
file b.txt:
abcd
You can find the difference with:
diff -a --suppress-common-lines -y a.txt b.txt
The output will be:
efgh
You can redirict the output in an output file (c.txt) using:
diff -a --suppress-common-lines -y a.txt b.txt > c.txt
This will answer your question:
"...which contains the lines in file1 which are not present in file2."
All the slowest (>100x) usages of Python on the shootout are scientific operations that require high GFlop/s count. You should NOT use python for those anyways.

VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.
Here is how to install it:
C:\Windows
called MSJAVA.DLL
. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.SETUP.EXE
, select Run As Administrator
.C:\Program Files\Microsoft Visual Studio\VB98\
After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

You can try joda-time.
There is actually a media query for that:
@media (hover: none) { … }
Apart from Firefox, it's fairly well supported. Safari and Chrome being the most common browsers on mobile devices, it might suffice untill greater adoption.
You can also use the [Required]
data annotation attribute to solve this:
public class Foo
{
public string FooId { get; set; }
public Boo Boo { get; set; }
}
public class Boo
{
public string BooId { get; set; }
[Required]
public Foo Foo {get; set; }
}
Foo
is required for Boo
.
As mentioned by Santosh, I think this query is suitably fast, while not querying all the table.
To return integer result of number of data records, for a specific tablename in a particular database:
select TABLE_ROWS from information_schema.TABLES where TABLE_SCHEMA = 'database'
AND table_name='tablename';
I created a class wrapped in an ES6 module that solves exactly this.
It's 103 lines, no dependencies, and fairly nicely structured and documented, meant to be easy to modify/reuse.
Handles all 8 possible orientations, and is Promise-based.

objdump
+ gdb
minimal runnable example
TL;DR:
objdump -s core
can be used to dump memory in bulkNow for the full educational test setup:
main.c
#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int myfunc(int i) {
*(int*)(NULL) = i; /* line 7 */
return i - 1;
}
int main(int argc, char **argv) {
/* Setup some memory. */
char data_ptr[] = "string in data segment";
char *mmap_ptr;
char *text_ptr = "string in text segment";
(void)argv;
mmap_ptr = (char *)malloc(sizeof(data_ptr) + 1);
strcpy(mmap_ptr, data_ptr);
mmap_ptr[10] = 'm';
mmap_ptr[11] = 'm';
mmap_ptr[12] = 'a';
mmap_ptr[13] = 'p';
printf("text addr: %p\n", text_ptr);
printf("data addr: %p\n", data_ptr);
printf("mmap addr: %p\n", mmap_ptr);
/* Call a function to prepare a stack trace. */
return myfunc(argc);
}
Compile, and run to generate core:
gcc -ggdb3 -std=c99 -Wall -Wextra -pedantic -o main.out main.c
ulimit -c unlimited
rm -f core
./main.out
Output:
text addr: 0x4007d4
data addr: 0x7ffec6739220
mmap addr: 0x1612010
Segmentation fault (core dumped)
GDB points us to the exact line where the segmentation fault happened, which is what most users want while debugging:
gdb -q -nh main.out core
then:
Reading symbols from main.out...done.
[New LWP 27479]
Core was generated by `./main.out'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x0000000000400635 in myfunc (i=1) at main.c:7
7 *(int*)(NULL) = i;
(gdb) bt
#0 0x0000000000400635 in myfunc (i=1) at main.c:7
#1 0x000000000040072b in main (argc=1, argv=0x7ffec6739328) at main.c:28
which points us directly to the buggy line 7.
CLI arguments are stored in the core file and don't need to be passed again
To answer the specific CLI argument questions, we see that if we change the cli arguments e.g. with:
rm -f core
./main.out 1 2
then this does get reflected in the previous bactrace without any changes in our commands:
Reading symbols from main.out...done.
[New LWP 21838]
Core was generated by `./main.out 1 2'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x0000564583cf2759 in myfunc (i=3) at main.c:7
7 *(int*)(NULL) = i; /* line 7 */
(gdb) bt
#0 0x0000564583cf2759 in myfunc (i=3) at main.c:7
#1 0x0000564583cf2858 in main (argc=3, argv=0x7ffcca4effa8) at main.c:2
So note how now argc=3
. Therefore this must mean that the core file stores that information. I'm guessing it just stores it as the arguments of main
, just like it stores the arguments of any other functions.
This makes sense if you consider that the core dump must be storing the entire memory and register state of the program, and so it has all the information needed to determine the value of function arguments on the current stack.
Less obvious is how to inspect the environment variables: How to get environment variable from a core dump Environment variables are also present in memory so the objdump does contain that information, but I'm not sure how to list all of them in one go conveniently, one by one as follows did work on my tests though:
p __environ[0]
Binutils analysis
By using binutils tools like readelf
and objdump
, we can bulk dump information contained in the core
file such as the memory state.
Most/all of it must also be visible through GDB, but those binutils tools offer a more bulk approach which is convenient for certain use cases, while GDB is more convenient for a more interactive exploration.
First:
file core
tells us that the core
file is actually an ELF file:
core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from './main.out'
which is why we are able to inspect it more directly with usual binutils tools.
A quick look at the ELF standard shows that there is actually an ELF type dedicated to it:
Elf32_Ehd.e_type == ET_CORE
Further format information can be found at:
man 5 core
Then:
readelf -Wa core
gives some hints about the file structure. Memory appears to be contained in regular program headers:
Program Headers:

objdump
can easily dump all memory with:
objdump -s core

which matches exactly with the stdout value in our run.
This was tested on Ubuntu 16.04 amd64, GCC 6.4.0, and binutils 2.26.1.
I use __get
(and public properties) as much as possible, because they make code much more readable. Compare:
this code unequivocally says what i'm doing:
echo $user->name;
this code makes me feel stupid, which i don't enjoy:
function getName() { return $this->_name; }
....
echo $user->getName();
The difference between the two is particularly obvious when you access multiple properties at once.
echo "
Dear $user->firstName $user->lastName!
Your purchase:
$product->name $product->count x $product->price
"
and
echo "
Dear " . $user->getFirstName() . " " . $user->getLastName() . "
Your purchase:
" . $product->getName() . " " . $product->getCount() . " x " . $product->getPrice() . " ";
Whether $a->b
should really do something or just return a value is the responsibility of the callee. For the caller, $user->name
and $user->accountBalance
should look the same, although the latter may involve complicated calculations. In my data classes i use the following small method:
function __get($p) {
$m = "get_$p";
if(method_exists($this, $m)) return $this->$m();
user_error("undefined property $p");
}
when someone calls $obj->xxx
and the class has get_xxx
defined, this method will be implicitly called. So you can define a getter if you need it, while keeping your interface uniform and transparent. As an additional bonus this provides an elegant way to memorize calculations:
function get_accountBalance() {
$result = <...complex stuff...>
// since we cache the result in a public property, the getter will be called only once
$this->accountBalance = $result;
}
....
echo $user->accountBalance; // calculate the value
....
echo $user->accountBalance; // use the cached value
Bottom line: php is a dynamic scripting language, use it that way, don't pretend you're doing Java or C#.
Or another possibility is to create Dialog as follow:
final Dialog dialog = new Dialog(new ContextThemeWrapper(
this, R.style.MyThemeDialog));
Pseudo elements like :after
, :before
are only for container elements. Elements starting and closing in a single place like <input/>
, <img>
etc are not container elements and hence pseudo elements are not supported. Once you apply a pseudo element to container element like <div>
and if you inspect the code(see the image) you can understand what I mean. Actually the pseudo element is created inside the container element. This is not possible in case of <input>
or <img>
I just had the same problem and ended up doing:
git rebase -i HEAD~N
(N is the number of commits git will show you)
That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.
Another option is using a map as a set. You use just the keys and having the value be something like a boolean that's always true. Then you can easily check if the map contains the key or not. This is useful if you need the behavior of a set, where if you add a value multiple times it's only in the set once.
Here's a simple example where I add random numbers as keys to a map. If the same number is generated more than once it doesn't matter, it will only appear in the final map once. Then I use a simple if check to see if a key is in the map or not.
package main
import (
"fmt"
"math/rand"
)
func main() {
var MAX int = 10
m := make(map[int]bool)
for i := 0; i <= MAX; i++ {
m[rand.Intn(MAX)] = true
}
for i := 0; i <= MAX; i++ {
if _, ok := m[i]; ok {
fmt.Printf("%v is in map\n", i)
} else {
fmt.Printf("%v is not in map\n", i)
}
}
}
No, you cannot. But you can create a user defined table function.
So the first part of the answer is how to do what the subject asks as this was how I initially interpreted it and a few people seemed to find helpful. The question was since clarified and I've extended the answer to address that.
Setting a timer
First you need to create a Timer (I'm using the java.util
version here):
import java.util.Timer;
..
Timer timer = new Timer();
To run the task once you would do:
timer.schedule(new TimerTask() {
@Override
public void run() {
// Your database code here
}
}, 2*60*1000);
// Since Java-8
timer.schedule(() -> /* your database code here */, 2*60*1000);
To have the task repeat after the duration you would do:
timer.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
// Your database code here
}
}, 2*60*1000, 2*60*1000);
// Since Java-8
timer.scheduleAtFixedRate(() -> /* your database code here */, 2*60*1000, 2*60*1000);
Making a task timeout
To specifically do what the clarified question asks, that is attempting to perform a task for a given period of time, you could do the following:
ExecutorService service = Executors.newSingleThreadExecutor();
try {
Runnable r = new Runnable() {
@Override
public void run() {
// Database task
}
};
Future<?> f = service.submit(r);
f.get(2, TimeUnit.MINUTES); // attempt the task for two minutes
}
catch (final InterruptedException e) {
// The thread was interrupted during sleep, wait or join
}
catch (final TimeoutException e) {
// Took too long!
}
catch (final ExecutionException e) {
// An exception from within the Runnable task
}
finally {
service.shutdown();
}
This will execute normally with exceptions if the task completes within 2 minutes. If it runs longer than that, the TimeoutException will be throw.
One issue is that although you'll get a TimeoutException after the two minutes, the task will actually continue to run, although presumably a database or network connection will eventually time out and throw an exception in the thread. But be aware it could consume resources until that happens.
You need to unicode each element of the list individually
[x.encode('utf-8') for x in tmp]
Use SQLCipher, it's an opensource extension for SQLite that provides transparent 256-bit AES encryption of database files. http://sqlcipher.net

String.Format must start with zero index "{0}" like this:
Aboutme.Text = String.Format("{0}", reader.GetString(0));
with underscore.js
use the findWhere method:
var array = [
{ name:"string 1", value:"this", other: "that" },
{ name:"string 2", value:"this", other: "that" }
];
var result = _.findWhere(array, {name: 'string 1'});
console.log(result.name);
See this in JSFIDDLE
You may not pass str
to fit this kind of classifier.
For example, if you have a feature column named 'grade' which has 3 different grades:
A,B and C.
you have to transfer those str
"A","B","C" to matrix by encoder like the following:
A = [1,0,0]
B = [0,1,0]
C = [0,0,1]
because the str
does not have numerical meaning for the classifier.
In scikit-learn, OneHotEncoder
and LabelEncoder
are available in inpreprocessing
module.
However OneHotEncoder
does not support to fit_transform()
of string.
"ValueError: could not convert string to float" may happen during transform.
You may use LabelEncoder
to transfer from str
to continuous numerical values. Then you are able to transfer by OneHotEncoder
as you wish.
In the Pandas dataframe, I have to encode all the data which are categorized to dtype:object
. The following code works for me and I hope this will help you.
from sklearn import preprocessing
le = preprocessing.LabelEncoder()
for column_name in train_data.columns:
if train_data[column_name].dtype == object:
train_data[column_name] = le.fit_transform(train_data[column_name])
else:
pass
This is spruced up from the answers just above and uses the length/number of options to conform to how many options there actually are.
Hope this helps somebody get the results they need!
function openDropdown(elementId) {
function down() {
var pos = $(this).offset(); // remember position
var len = $(this).find("option").length;
if(len > 20) {
len = 20;
}
$(this).css("position", "absolute");
$(this).css("zIndex", 9999);
$(this).offset(pos); // reset position
$(this).attr("size", len); // open dropdown
$(this).unbind("focus", down);
$(this).focus();
}
function up() {
$(this).css("position", "static");
$(this).attr("size", "1"); // close dropdown
$(this).unbind("change", up);
$(this).focus();
}
$("#" + elementId).focus(down).blur(up).focus();
}
The selected answer doesn't help if you don't know the name of projects you have added gcloud already. My flow is to list the active projects, then switch to the one I want.
gcloud config configurations list
gcloud config configurations activate [NAME]
where [NAME] is listed from the prior command.
For newer versions of Git there is git restore --staged <file>
.
When I do a git status
with Git version 2.26.2.windows.1
it is also recommended for unstaging:
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
(This post shows, that in earlier versions git reset HEAD
was recommended at this point)
I can highly recommend this post explaining the differences between git revert
, git restore
and git reset
and also additional parameters for git restore
.
String
vs string
Argument of type 'String' is not assignable to parameter of type 'string'.
'string' is a primitive, but 'String' is a wrapper object.
Prefer using 'string' when possible.

Rather than using a proxy, I'm using the Firefox plugin "Modify Headers" to insert headers (in my case, to fake a login using the Single Sign On so I can test as different people).
Well you can convert one byte (unsigned char) at a time into a array like so
char buffer [17];
buffer[16] = 0;
for(j = 0; j < 8; j++)
sprintf(&buffer[2*j], "%02X", data[j]);

There are already nice solution has been given. The below code can help others to query over datatable and get the value of each row of the datatable for the ImagePath column.
for (int i = 0; i < dataTable.Rows.Count; i++)
{
var theUrl = dataTable.Rows[i]["ImagePath"].ToString();
}
This is a simple example and try to combine it with yours using some modifications. I prefer you set all the images in one array in order to make your code easier to read and shorter:
var myImage = document.getElementById("mainImage");
var imageArray = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg",
"_images/image4.jpg","_images/image5.jpg","_images/image6.jpg"];
var imageIndex = 0;
function changeImage() {
myImage.setAttribute("src",imageArray[imageIndex]);
imageIndex = (imageIndex + 1) % imageArray.length;
}
setInterval(changeImage, 5000);
I was able to resolve this in Visual Studio 2010, VB.net (ASP.NET) 4.0.
During the entity model wizard, you will be able to see the entity connection string. From there you can copy and paste into your connection string.
The only thing I was missing was the "App_Code." in the connections string.
entityBuilder.Metadata = "res://*/App_Code.Model.csdl|res://*/App_Code.Model.ssdl|res://*/App_Code.Model.msl"
Try this, using mkdir:
if (!file_exists('path/to/directory')) {
mkdir('path/to/directory', 0777, true);
}
Note that 0777
is already the default mode for directories and may still be modified by the current umask.
You are accessing the list elements and then using them to attempt to index your list. This is not a good idea. You already have an answer showing how you could use indexing to get your sum list, but another option would be to zip
the list with a slice of itself such that you can sum the pairs.
b = [i + j for i, j in zip(a, a[1:])]
Have a look at the AlertDialog docs. As it states, to add a custom view to your alert dialog you need to find the frameLayout and add your view to that like so:
FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
Most likely you are going to want to create a layout xml file for your view, and inflate it:
LayoutInflater inflater = getLayoutInflater();
View twoEdits = inflater.inflate(R.layout.my_layout, f1, false);
Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:
public class CtorTest {
public static void main(String[] args) {
final Sub sub = new Sub();
System.err.println("Finished.");
}
private static class Base {
public Base() {
System.err.println("In Base ctor");
}
}
private static class Sub extends Base {
public Sub() {
System.err.println("In Sub ctor");
}
}
}
If you want to explicitly call a constructor from a super class, you need to do something like this:
public class Ctor2Test {
public static void main(String[] args) {
final Sub sub = new Sub();
System.err.println("Finished.");
}
private static class Base {
public Base() {
System.err.println("In Base ctor");
}
public Base(final String toPrint) {
System.err.println("In Base ctor. To Print: " + toPrint);
}
}
private static class Sub extends Base {
public Sub() {
super("Hello World!");
System.err.println("In Sub ctor");
}
}
}
The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.
To split the string ({filepath}/{filename}) and get the file name you could use something like this:
str.split(/(\\|\/)/g).pop()
"The pop method removes the last element from an array and returns that value to the caller."
Mozilla Developer Network
Example:
from: "/home/user/file.txt".split(/(\\|\/)/g).pop()
you get: "file.txt"
Try this one. Without using controller
{{ Form::select('apartment_id', \App\Apartment::all()->pluck('apartment_name', 'apartment_id')->toArray(), null,['class'=>'select2 form-control', 'multiple'=>'multiple','required','id' => 'apartment_id']) }}
Not exactly direct answer, but strongly related:
In case the resources are in a different file - for example ResourceDictionary.xaml
You can simply add x:Class
to it:
<ResourceDictionary x:Class="Namespace.NewClassName"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<ds:MyCollection x:Key="myKey" x:Name="myName" />
</ResourceDictionary>
And then use it in code behind:
var res = new Namespace.NewClassName();
var col = res["myKey"];
I used the method that you accepted a lot, but as someone pointed out it doesn't duplicate constraints (except for NOT NULL, I think).
A more advanced method if you want to duplicate the full structure is:
SET LONG 5000
SELECT dbms_metadata.get_ddl( 'TABLE', 'MY_TABLE_NAME' ) FROM DUAL;
This will give you the full create statement text which you can modify as you wish for creating the new table. You would have to change the names of the table and all constraints of course.
(You could also do this in older versions using EXP/IMP, but it's much easier now.)
Edited to add If the table you are after is in a different schema:
SELECT dbms_metadata.get_ddl( 'TABLE', 'MY_TABLE_NAME', 'OTHER_SCHEMA_NAME' ) FROM DUAL;
It refers to which filegroup the object you are creating resides on. So your Primary filegroup could reside on drive D:\ of your server. you could then create another filegroup called Indexes. This filegroup could reside on drive E:\ of your server.
If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:
class YourNonActivityClass{
// variable to hold context
private Context context;
//save the context recievied via constructor in a local variable
public YourNonActivityClass(Context context){
this.context=context;
}
}
You can create instance of this class from the activity as follows:
new YourNonActivityClass(this);
With jQuery (and without FormData API) you can use something like this:
function readFile(file){
var loader = new FileReader();
var def = $.Deferred(), promise = def.promise();
//--- provide classic deferred interface
loader.onload = function (e) { def.resolve(e.target.result); };
loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
loader.onerror = loader.onabort = function (e) { def.reject(e); };
promise.abort = function () { return loader.abort.apply(loader, arguments); };
loader.readAsBinaryString(file);
return promise;
}
function upload(url, data){
var def = $.Deferred(), promise = def.promise();
var mul = buildMultipart(data);
var req = $.ajax({
url: url,
data: mul.data,
processData: false,
type: "post",
async: true,
contentType: "multipart/form-data; boundary="+mul.bound,
xhr: function() {
var xhr = jQuery.ajaxSettings.xhr();
if (xhr.upload) {
xhr.upload.addEventListener('progress', function(event) {
var percent = 0;
var position = event.loaded || event.position; /*event.position is deprecated*/
var total = event.total;
if (event.lengthComputable) {
percent = Math.ceil(position / total * 100);
def.notify(percent);
}
}, false);
}
return xhr;
}
});
req.done(function(){ def.resolve.apply(def, arguments); })
.fail(function(){ def.reject.apply(def, arguments); });
promise.abort = function(){ return req.abort.apply(req, arguments); }
return promise;
}
var buildMultipart = function(data){
var key, crunks = [], bound = false;
while (!bound) {
bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
}
for (var key = 0, l = data.length; key < l; key++){
if (typeof(data[key].value) !== "string") {
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
"Content-Type: application/octet-stream\r\n"+
"Content-Transfer-Encoding: binary\r\n\r\n"+
data[key].value[0]);
}else{
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
data[key].value);
}
}
return {
bound: bound,
data: crunks.join("\r\n")+"\r\n--"+bound+"--"
};
};
//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
var formData = form.find(":input:not('#file')").serializeArray();
formData.file = [fileData, $file[0].files[0].name];
upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});
With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})
types.Values.ToList().IndexOf("one");
Values.ToList() converts your dictionary values into a List of objects. IndexOf("one") searches your new List looking for "one" and returns the Index which would match the index of the Key/Value pair in the dictionary.
This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.
Keep in mind there may be more than one "one" value in your dictionary. And that is the reason there is no "get key" method.
Try this one.. Source from here.

If you want to keep the upstream repository with full history, but local smaller checkouts, do a shallow clone with git clone --depth=1 [repo]
.
After pushing a commit, you can do
git fetch --depth=1
to prune the old commits. This makes the old commits and their objects unreachable.git reflog expire --expire-unreachable=now --all
. To expire all old commits and their objectsgit gc --aggressive --prune=all
to remove the old objectsSee also How to remove local git history after a commit?.
Note that you cannot push this "shallow" repository to somewhere else: "shallow update not allowed". See Remote rejected (shallow update not allowed) after changing Git remote URL. If you want to to that, you have to stick with grafting.
const log = chrome.extension.getBackgroundPage().console.log;

Open log:
To convert any array (or any object) into a string using PHP, call the serialize():
$array = array( 1, 2, 3 );
$string = serialize( $array );
echo $string;
$string will now hold a string version of the array. The output of the above code is as follows:
a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}
To convert back from the string to the array, use unserialize():
// $array will contain ( 1, 2, 3 )
$array = unserialize( $string );
It is an old post, but I will try to update it with a new information.
To use custom events you need to bind it to some DOM element and to trigger it. So you need to use
.on() method takes an event type and an event handling function as arguments. Optionally, it can also receive event-related data as its second argument, pushing the event handling function to the third argument. Any data that is passed will be available to the event handling function in the data property of the event object. The event handling function always receives the event object as its first argument.
and
.trigger() method takes an event type as its argument. Optionally, it can also take an array of values. These values will be passed to the event handling function as arguments after the event object.
The code looks like this:
$(document).on("getMsg", {
msg: "Hello to everyone",
time: new Date()
}, function(e, param) {
console.log( e.data.msg );
console.log( e.data.time );
console.log( param );
});
$( document ).trigger("getMsg", [ "Hello guys"] );
Nice explanation can be found here and here. Why exactly this can be useful? I found how to use it in this excellent explanation from twitter engineer.
P.S. In plain javascript you can do this with new CustomEvent, but beware of IE and Safari problems.
The acceptable verbs are controlled in web.config (found in the root of the website) in <system.web><httpHandlers>
and possibly <webServices><protocols>
. Web.config will be accessible to you if it exists. There is also a global server.config which probably won't. If you can get a look at either of these you may get a clue.
The acceptable verbs can differ with the content types - have you set Content-type headers in your page at all ? (i.e. if your Content-type was application/json then different verbs would be allowed)
CASE
WHEN last_name IS null THEN ''
ELSE ' ' + last_name
END
You can use the LIKE operator to compare the content of a T-SQL string, e.g.
SELECT * FROM [table] WHERE [field] LIKE '%stringtosearchfor%'.
The percent character '%' is a wild card- in this case it says return any records where [field] at least contains the value "stringtosearchfor".
I heartily recommended dbVis. The client runs on Mac, Windows and Linux and supports a variety of database servers, including PostgreSQL.
However -just for the record- this is invalid:
<address class="vcard">
<svg viewBox="0 0 800 400">
<rect width="800" height="400" fill="#000">
</svg>
</address>
And a slash here would make it valid again:
<rect width="800" height="400" fill="#000"/>
In Eclipse, Goto Window-> Show View -> Other -> Android-> Logcat.
Logcat is nothing but a console of your Emulator or Device.
System.out.println
does not work in Android. So you have to handle every thing in Logcat. More Info Look out this Documentation.
Edit 1: System.out.println is working on Logcat. If you use that the Tag will be like System.out and Message will be your message.
To post JSON, you will need to stringify it. JSON.stringify
and set the processData
option to false.
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(data),
processData: false,
contentType: "application/json; charset=UTF-8",
complete: callback
});
Not the answer for this question but this question helped me to find the answer for my problem.
I had this problem when using inside a Docker container.
I solved by installing locales, adding my language to the locale.gen file, executing locale-gen (it reads from locale.gen) and finally setting LANG to my language.
For example, my Dockerfile:
RUN apt-get install -y locales
RUN echo "pt_BR.UTF-8 UTF-8" >> /etc/locale.gen
RUN locale-gen pt_BR.UTF-8
ENV LANG=pt_BR.UTF-8
This error occurs on the server side when the client closed the socket connection before the response could be returned over the socket. In a web app scenario not all of these are dangerous, since they can be created manually. For example, by quitting the browser before the reponse was retrieved.
Use this to obtain only the filename.
Path.GetFileName(files[0]);
the best answer is @Gal Rom 's. there is more information about it: touch event return's to child views first. and if you define onClick or onTouch listener for them, parnt view (for example fragment) will not receive any touch listener. So if you want define swipe listener for fragment in this situation, you must implement it in a new class:
package com.neganet.QRelations.fragments;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.FrameLayout;
public class SwipeListenerFragment extends FrameLayout {
private float x1,x2;
static final int MIN_DISTANCE=150;
private onSwipeEventDetected mSwipeDetectedListener;
public SwipeListenerFragment(Context context) {
super(context);
}
public SwipeListenerFragment(Context context, AttributeSet attrs) {
super(context, attrs);
}
public SwipeListenerFragment(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
boolean result=false;
switch(ev.getAction())
{
case MotionEvent.ACTION_DOWN:
x1 = ev.getX();
break;
case MotionEvent.ACTION_UP:
x2 = ev.getX();
float deltaX = x2 - x1;
if (Math.abs(deltaX) > MIN_DISTANCE)
{
if(deltaX<0)
{
result=true;
if(mSwipeDetectedListener!=null)
mSwipeDetectedListener.swipeLeftDetected();
}else if(deltaX>0){
result=true;
if(mSwipeDetectedListener!=null)
mSwipeDetectedListener.swipeRightDetected();
}
}
break;
}
return result;
}
public interface onSwipeEventDetected
{
public void swipeLeftDetected();
public void swipeRightDetected();
}
public void registerToSwipeEvents(onSwipeEventDetected listener)
{
this.mSwipeDetectedListener=listener;
}
}
I changed @Gal Rom 's class. So it can detect both right and left swipe and specially it returns onInterceptTouchEvent true after detect. its important because if we dont do it some times child views maybe receive event and both of Swipe for fragment and onClick for child view (for example) runs and cause some issues. after making this class, you must change your fragment xml file:
<com.neganet.QRelations.fragments.SwipeListenerFragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:id="@+id/main_list_layout"
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_height="match_parent" tools:context="com.neganet.QRelations.fragments.mainList"
android:background="@color/main_frag_back">
<!-- TODO: Update blank fragment layout -->
<android.support.v7.widget.RecyclerView
android:id="@+id/farazList"
android:scrollbars="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="left|center_vertical" />
</com.neganet.QRelations.fragments.SwipeListenerFragment>
you see that begin tag is the class that we made. now in fragment class:
View view=inflater.inflate(R.layout.fragment_main_list, container, false);
SwipeListenerFragment tdView=(SwipeListenerFragment) view;
tdView.registerToSwipeEvents(this);
and then Implement SwipeListenerFragment.onSwipeEventDetected in it:
@Override
public void swipeLeftDetected() {
Toast.makeText(getActivity(), "left", Toast.LENGTH_SHORT).show();
}
@Override
public void swipeRightDetected() {
Toast.makeText(getActivity(), "right", Toast.LENGTH_SHORT).show();
}
It's a little complicated but works perfect :)
An example (axios_example.js) using Axios in Node.js:
const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;
app.get('/search', function(req, res) {
let query = req.query.queryStr;
let url = `https://your.service.org?query=${query}`;
axios({
method:'get',
url,
auth: {
username: 'xxxxxxxxxxxxx',
password: 'xxxxxxxxxxxxx'
}
})
.then(function (response) {
res.send(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
});
var server = app.listen(port);
Be sure in your project directory you do:
npm init
npm install express
npm install axios
node axios_example.js
You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx
This can be done by using PsExec
which can be downloaded here
psexec \\computer_name -u username -p password ipconfig
If this isn't working try doing this :-
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.
Add a new DWORD value called LocalAccountTokenFilterPolicy
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
I feel like all that was wrong here was the order, Selçuklu wanted the app to wait for a second before filling in the grid, so the Sleep command should have come before the fill command.
System.Threading.Thread.Sleep(1000);
dataGridView1.Rows[x1].Cells[y1].Style.BackColor = System.Drawing.Color.Red;
you can use java http/https url connection to get the response code from the website and other information as well here is a sample code.
try {
url = new URL("https://www.google.com"); // create url object for the given string
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
if(https_url.startsWith("https")){
connection = (HttpsURLConnection) url.openConnection();
}
((HttpURLConnection) connection).setRequestMethod("HEAD");
connection.setConnectTimeout(50000); //set the timeout
connection.connect(); //connect
String responseMessage = connection.getResponseMessage(); //here you get the response message
responseCode = connection.getResponseCode(); //this is http response code
System.out.println(obj.getUrl()+" is up. Response Code : " + responseMessage);
connection.disconnect();`
}catch(Exception e){
e.printStackTrace();
}

I know this is a very old post but this may help someone:
You can create a method, so whenever you need to pause you can type pause(1000)
or any other millisecond value:
public static void pause(int ms) {
try {
Thread.sleep(ms);
} catch (InterruptedException e) {
System.err.format("IOException: %s%n", e);
}
}
This is inserted just above the public static void main(String[] args)
, inside the class. Then, to call on the method, type pause(ms)
but replace ms
with the number of milliseconds to pause. That way, you don't have to insert the entire try-catch statement whenever you want to pause.
public static void copyInputStreamToFile(InputStream input, File file) {
try (OutputStream output = new FileOutputStream(file)) {
input.transferTo(output);
} catch (IOException ioException) {
ioException.printStackTrace();
}
}
java.io.InputStream#transferTo is available since Java 9.
I wasn't aware of a problem with setAttribute
in IE ? However you could directly set the expando property on the node itself:
hiddenInput.id = "uniqueIdentifier";
Since there are no limits to the length of text in a data attribute, use data attributes! And then you can use regular css selectors to select your element(s) like the OP wants.
for (const element of document.querySelectorAll("*")) {_x000D_
element.dataset.myInnerText = element.innerText;_x000D_
}_x000D_
_x000D_
document.querySelector("*[data-my-inner-text='Different text.']").style.color="blue";
_x000D_
<div>SomeText, text continues.</div>_x000D_
<div>Different text.</div>
_x000D_
Ideally you do the data attribute setting part on document load and narrow down the querySelectorAll selector a bit for performance.
One possibility is to create a wrapper for an ArrayList that only provides one method: one that adds things to the ArrayList. Make the ArrayList itself private. Now, construct one of these wrapper objects in global scope (as a static object in a class) and qualify it with the final keyword (e.g. public static final ArrayListWrapper wrapperClass = new ArrayListWrapper()
). So now the reference cannot be altered. That is, wrapperClass = null
won't work and can't be used to free the memory. But there's also no way to do anything with wrapperClass
other than add objects to it. Therefore, any objects you do add to wrapperClass
are impossible to recycle.
The default configuration of most SMTP servers is not to relay from an untrusted source to outside domains. For example, imagine that you contact the SMTP server for foo.com and ask it to send a message to [email protected]. Because the SMTP server doesn't really know who you are, it will refuse to relay the message. If the server did do that for you, it would be considered an open relay, which is how spammers often do their thing.
If you contact the foo.com mail server and ask it to send mail to [email protected], it might let you do it. It depends on if they trust that you're who you say you are. Often, the server will try to do a reverse DNS lookup, and refuse to send mail if the IP you're sending from doesn't match the IP address of the MX record in DNS. So if you say that you're the bar.com mail server but your IP address doesn't match the MX record for bar.com, then it will refuse to deliver the message.
You'll need to talk to the administrator of that SMTP server to get the authentication information so that it will allow relay for you. You'll need to present those credentials when you contact the SMTP server. Usually it's either a user name/password, or it can use Windows permissions. Depends on the server and how it's configured.
See Unable to send emails to external domain using SMTP for an example of how to send the credentials.
If anyone is trying to solve this on a 64-bit version of Windows, you might need to create the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Prefs
values method of enum
enum.values() method which returns all enum instances.
public class EnumTest {
private enum Currency {
PENNY("1 rs"), NICKLE("5 rs"), DIME("10 rs"), QUARTER("25 rs");
private String value;
private Currency(String brand) {
this.value = brand;
}
@Override
public String toString() {
return value;
}
}
public static void main(String args[]) {
Currency[] currencies = Currency.values();
// enum name using name method
// enum to String using toString() method
for (Currency currency : currencies) {
System.out.printf("[ Currency : %s,
Value : %s ]%n",currency.name(),currency);
}
}
}

You can raise a notice in Postgres
as follows:
raise notice 'Value: %', deletedContactId;

Re: SELECT * INTO OUTFILE
Check if MySQL has permissions to write a file to the OUTFILE directory on the server.
You might be missing this:
services.AddScoped<IDependencyTwoThatIsDependentOnDependencyOne, DependencyTwoThatIsDependentOnDependencyOne>();
You can easily re-export the default import:
export {default as Comp1} from './Comp1.jsx';
export {default as Comp2} from './Comp2.jsx';
export {default as Comp3} from './Comp3.jsx';
There also is a proposal for ES7 ES8 that will let you write export Comp1 from '…';
.
You seem to be emphasizing the need for a positional association with your data, so wouldn't an associative array be more fitting?
Dictionary<int, string> foo = new Dictionary<int, string>();
foo[2] = "string";
This answer is no longer the best answer ... see the flexbox answer below instead!
To get it perfectly centered (as mentioned in david's answer) you need to add a negative top margin. If you know (or force) there to only be a single line of text, you can use:
margin-top: -0.5em;
for example:
http://jsfiddle.net/45MHk/623/
//CSS:
html, body, div {
height: 100%;
}
#parent
{
position:relative;
border: 1px solid black;
}
#child
{
position: absolute;
top: 50%;
/* adjust top up half the height of a single line */
margin-top: -0.5em;
/* force content to always be a single line */
overflow: hidden;
white-space: nowrap;
width: 100%;
text-overflow: ellipsis;
}
//HTML:
<div id="parent">
<div id="child">Text that is suppose to be centered</div>
</div>?
The originally accepted answer will not vertically center on the middle of the text (it centers based on the top of the text). So, if you parent is not very tall, it will not look centered at all, for example:
//CSS:
#parent
{
position:relative;
height: 3em;
border: 1px solid black;
}
#child
{
position: absolute;
top: 50%;
}?
//HTML:
<div id="parent">
<div id="child">Text that is suppose to be centered</div>
</div>?
if you want to "clean" the new lines, flamebaud comment using regex @"[\r\n]+"
is the best choice.
using System;
using System.Text.RegularExpressions;
class MainClass {
public static void Main (string[] args) {
string str = "AAA\r\nBBB\r\n\r\n\r\nCCC\r\r\rDDD\n\n\nEEE";
Console.WriteLine (str.Replace(System.Environment.NewLine, "-"));
/* Result:
AAA
-BBB
-
-
-CCC
DDD---EEE
*/
Console.WriteLine (Regex.Replace(str, @"\r\n?|\n", "-"));
// Result:
// AAA-BBB---CCC---DDD---EEE
Console.WriteLine (Regex.Replace(str, @"[\r\n]+", "-"));
// Result:
// AAA-BBB-CCC-DDD-EEE
}
}
You can get the full path of the selected file to upload only by IE11 and MS Edge.
var fullPath = Request.Form.Files["myFile"].FileName;
