Just you need to modify a single file in PHPMyAdmin folder i.e. “config.inc.php”.Just add below lines to your “config.inc.php”.
File location : /var/lib/phpmyadmin/config.inc.php
OR
/etc/phpmyadmin/config.inc.php
Maybe you don't have the permission for editing that file, just give the permission using this command
sudo chmod 777 /var/lib/phpmyadmin/config.inc.php
OR (in different systems you may have to check with these two locations)
sudo chmod 777 /etc/phpmyadmin/config.inc.php
Then copy and paste the code in your config.inc.php
file
$i++;
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['verbose'] = 'Database Server 2';
$cfg['Servers'][$i]['host'] = '34.12.123.31';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['AllowNoPassword'] = false;
And make the appropriate changes with your server details
The solution above was not working for me. I had to set 'class count to use import with '*'' to a high value, e.g. 999.

You may need to call frame.repaint()
as well to force the frame to actually redraw itself. I've had issues before where I tried to repaint a component and it wasn't updating what was displayed until the parent's repaint() method was called.
You must put the return inside submit() call.
$('.submit').click(function() {
$('#registerform').submit(function () {
sendContactForm();
return false;
});
//Here you can do anything after submit
}
this will sort it for you
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button but1=(Button)findViewById(R.id.button1);
but1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent int1= new Intent(MainActivity.this,xxactivity.class);
startActivity(int1);
}
});
}
You just need to amend the xxactivity to the name of your second activity
You could also use strdup
:
The strdup() function returns a pointer to a new string which is a duplicate of the string s.
Memory for the new string is obtained with malloc(3), and can be freed with free(3).
For you example:
char *a = strdup("stack overflow");
import re
re.sub(r'''(?i)\b((?:https?://|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'".,<>?«»“”‘’]))''', " ", text)

In case you are trying to log all errors make sure you keep Task.WhenAll line in your code, lot of comments suggest that you can remove it and wait for individual tasks. Task.WhenAll is really important for error handling. Without this line you potentially leaving your code open for unobserved exceptions.
var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();
await Task.WhenAll(catTask, houseTask, carTask);
var cat = await catTask;
var house = await houseTask;
var car = await carTask;
Imagine FeedCat throws exception in the following code:
var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();
var cat = await catTask;
var house = await houseTask;
var car = await carTask;
In that case you will never await on houseTask nor carTask. There are 3 possible scenarios here:
SellHouse is already completed successfully when FeedCat failed. In this case you are fine.
SellHouse is not complete and fails with exception at some point. Exception is not observed and will be rethrown on finalizer thread.
SellHouse is not complete and contains awaits inside it. In case your code runs in ASP.NET SellHouse will fail as soon as some of the awaits will completed inside it. This happens because you basically made fire & forget call and synchronization context was lost as soon as FeedCat failed.
Here is error that you will get for case (3):
System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. ---> System.NullReferenceException: Object reference not set to an instance of an object.

at System.Web.Util.SynchronizationHelper.SafeWrapCallback(Action action)

at System.Web.HttpApplication.System.Web.Util.ISyncContext.Enter()
at System.Web.Util.SynchronizationHelper.SafeWrapCallback(Action action)
at System.Threading.Tasks.Task.Execute()<---
For case (2) you will get similar error but with original exception stack trace.
For .NET 4.0 and later you can catch unobserved exceptions using TaskScheduler.UnobservedTaskException. For .NET 4.5 and later unobserved exceptions are swallowed by default for .NET 4.0 unobserved exception will crash your process.

Two steps works fine:
create table bu_x as (select a,b,c,d from x ) WITH no data;
insert into bu_x (a,b,c,d) select select a,b,c,d from x ;
Most of the answers seem to assume that iterative
= for loop
. If your for loop is unrestricted (a la C, you can do whatever you want with your loop counter), then that is correct. If it's a real for
loop (say as in Python or most functional languages where you cannot manually modify the loop counter), then it is not correct.
All (computable) functions can be implemented both recursively and using while
loops (or conditional jumps, which are basically the same thing). If you truly restrict yourself to for loops
, you will only get a subset of those functions (the primitive recursive ones, if your elementary operations are reasonable). Granted, it's a pretty large subset which happens to contain every single function you're likely to encouter in practice.
What is much more important is that a lot of functions are very easy to implement recursively and awfully hard to implement iteratively (manually managing your call stack does not count).
var user = [
{ id: 1, name: 'Siddhu' },
{ id: 2, name: 'Siddhartha' },
{ id: 3, name: 'Tiwary' }
];
var recToRemove={ id: 1, name: 'Siddhu' };
user.splice(user.indexOf(recToRemove),1)
I find the check-and-invoke code which needs to be littered within all methods related to forms to be way too verbose and unneeded. Here's a simple extension method which lets you do away with it completely:
public static class Extensions
{
public static void Invoke<TControlType>(this TControlType control, Action<TControlType> del)
where TControlType : Control
{
if (control.InvokeRequired)
control.Invoke(new Action(() => del(control)));
else
del(control);
}
}
And then you can simply do this:
textbox1.Invoke(t => t.Text = "A");
No more messing around - simple.
To be clear and answer @Dean's question: EBS-type root storage doesn't seem to be ephemeral. Data is persistent across reboots and actually it doesn't make any sense to use ebs-backed root volume which is 'ephemeral'. This wouldn't be different from image-based root volume.
Define your target selector(highlightLetter:
) with argument as
UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)];
Then you can get view by
- (void)highlightLetter:(UITapGestureRecognizer*)sender {
UIView *view = sender.view;
NSLog(@"%d", view.tag);//By tag, you can find out where you had tapped.
}
I use the following object:
function Padder(len, pad) {
if (len === undefined) {
len = 1;
} else if (pad === undefined) {
pad = '0';
}
var pads = '';
while (pads.length < len) {
pads += pad;
}
this.pad = function (what) {
var s = what.toString();
return pads.substring(0, pads.length - s.length) + s;
};
}
With it you can easily define different "paddings":
var zero4 = new Padder(4);
zero4.pad(12); // "0012"
zero4.pad(12345); // "12345"
zero4.pad("xx"); // "00xx"
var x3 = new Padder(3, "x");
x3.pad(12); // "x12"
I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:
Assembly myAssembly = Assembly.GetExecutingAssembly();
System.Reflection
namespace.
If you want to examine an assembly that you have no reference to, you can use either of these:
Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);
If you intend to instantiate your type once you've found it:
Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);
See the Assembly class documentation for more information.
Once you have the reference to the Assembly
object, you can use assembly.GetTypes()
like Jon already demonstrated.
It is not clear why you want to do this. If you want to get the correct numerical value, you could use unary +
[docs]:
value = +value;
If you just want to format the text, then regex could be better. It depends on the values you are dealing with I'd say. If you only have integers, then
input.value = +input.value;
is fine as well. Of course it also works for float values, but depending on how many digits you have after the point, converting it to a number and back to a string could (at least for displaying) remove some.
You'll have to use a setTimeout
(like you are) but also store the reference so you can keep resetting the limit. Something like:
//_x000D_
// $('#element').donetyping(callback[, timeout=1000])_x000D_
// Fires callback when a user has finished typing. This is determined by the time elapsed_x000D_
// since the last keystroke and timeout parameter or the blur event--whichever comes first._x000D_
// @callback: function to be called when even triggers_x000D_
// @timeout: (default=1000) timeout, in ms, to to wait before triggering event if not_x000D_

//_x000D_
;(function($){_x000D_
$.fn.extend({_x000D_
donetyping: function(callback,timeout){_x000D_
timeout = timeout || 1e3; // 1 second default timeout_x000D_
var timeoutReference,_x000D_
doneTyping = function(el){_x000D_
if (!timeoutReference) return;_x000D_
timeoutReference = null;_x000D_
callback.call(el);_x000D_
};_x000D_
return this.each(function(i,el){_x000D_
var $el = $(el);_x000D_
// Chrome Fix (Use keyup over keypress to detect backspace)_x000D_
// thank you @palerdot_x000D_
$el.is(':input') && $el.on('keyup keypress paste',function(e){_x000D_
// This catches the backspace button in chrome, but also prevents_x000D_

_x000D_
// Check if timeout has been set. If it has, "reset" the clock and_x000D_
// start over again._x000D_
if (timeoutReference) clearTimeout(timeoutReference);_x000D_
timeoutReference = setTimeout(function(){_x000D_
// if we made it here, our timeout has elapsed. Fire the_x000D_
// callback_x000D_
doneTyping(el);_x000D_
}, timeout);_x000D_
}).on('blur',function(){_x000D_
// If we can, fire the event since we're leaving the field_x000D_
doneTyping(el);_x000D_
});_x000D_
});_x000D_
}_x000D_
});_x000D_
})(jQuery);_x000D_
_x000D_
$('#example').donetyping(function(){_x000D_
$('#example-output').text('Event last fired @ ' + (new Date().toUTCString()));_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="text" id="example" />_x000D_
<p id="example-output">Nothing yet</p>
_x000D_
That will execute when:
blur
event)(Whichever comes first)
As written in the documentation, the way to trigger form validation programmatically is to invoke validator.form()
var validator = $( "#myform" ).validate();
validator.form();
For example if you want to repeat a word called "HELP" for 1000 times the following is the best way.
word = ['HELP']
repeat = 1000 * word
Then you will get the list of 1000 words and make that into a data frame if you want by using following command
word_data =pd.DataFrame(repeat)
word_data.columns = ['list_of_words'] #To change the column name
Either escape the quote:
$text1= "From time to \"time\"";
or use single quotes to denote your string:
$text1= 'From time to "time"';
Adding up to what Micheal has said:
You can use Predicate as follows in filtering collections in java:
public static <T> Collection<T> filter(final Collection<T> target,
final Predicate<T> predicate) {
final Collection<T> result = new ArrayList<T>();
for (final T element : target) {
if (predicate.apply(element)) {
result.add(element);
}
}
return result;
}
one possible predicate can be:
final Predicate<DisplayFieldDto> filterCriteria =
new Predicate<DisplayFieldDto>() {
public boolean apply(final DisplayFieldDto displayFieldDto) {
return displayFieldDto.isDisplay();
}
};
Usage:
final List<DisplayFieldDto> filteredList=
(List<DisplayFieldDto>)filter(displayFieldsList, filterCriteria);
You are likely running the Mac default (/usr/bin/python) which has an older version of numpy installed in the system folders. The easiest way to get python working with opencv is to use brew to install both python and opencv into /usr/local and run the /usr/local/bin/python.
brew install python
brew tap homebrew/science
brew install opencv
If you want to use a string key generated in your Node.js program, say, var v = 'HOME'
, you can use
process.env[v]
.
Otherwise, process.env.VARNAME
has to be hardcoded in your program.
A reasonable thing you can do is to convert the list into a dict and then access it with the get method:
>>> my_list = ['a', 'b', 'c', 'd', 'e']
>>> my_dict = dict(enumerate(my_list))
>>> print my_dict
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e'}
>>> my_dict.get(2)
'c'
>>> my_dict.get(10, 'N/A')

Dimensions are same after compressing Bitmap.
How did I checked ?
Bitmap beforeBitmap = BitmapFactory.decodeFile("Your_Image_Path_Here");
Log.i("Before Compress Dimension", beforeBitmap.getWidth()+"-"+beforeBitmap.getHeight());
Bitmap afterBitmap = ImageUtils.getInstant().getCompressedBitmap("Your_Image_Path_Here");
Log.i("After Compress Dimension", afterBitmap.getWidth() + "-" + afterBitmap.getHeight());
Output:
Before Compress : Dimension: 1080-1452
After Compress : Dimension: 1080-1452
Hope this will help you.
The best way I know how to do this, is:
1) set overflow to scroll and that way the image would stay in but you can scroll to see it instead
2) upload a smaller image. Now there are plenty of programs out there when uploading (you'll need something like PHP or .net to do this btw) you can have it auto scale.
3) Living with it and setting the width and height, this although will make it look distorted but the right size will still result in the user having to download the full-sized image.
Good luck!
Most likely, the userdata()
function is returning an object, not a string. Look into the documentation (or var_dump the return value) to find out which value you need to use.
Even if you write a regular expression that matches exactly the subset "valid phone numbers" out of strings, there is no way to guarantee (by way of a regular expression) that they are valid mobile phone numbers. In several countries, mobile phone numbers are indistinguishable from landline phone numbers without at least a number plan lookup, and in some cases, even that won't help. For example, in Sweden, lots of people have "ported" their regular, landline-like phone number to their mobile phone. It's still the same number as they had before, but now it goes to a mobile phone instead of a landline.
Since valid phone numbers consist only of digits, I doubt that rolling your own would risk missing some obscure case of phone number at least. If you want to have better certainty, write a generator that takes a list of all valid country codes, and requires one of them at the beginning of the phone number to be matched by the generated regular expression.
document.addEventListener('scroll', function (event) {
if ((<HTMLInputElement>event.target).id === 'latest-div') { // or any other filtering condition
}
}, true /*Capture event*/);
You can use this to capture an event and and here "latest-div" is the id name so u can capture all scroller action here based on the id you can do the action as well inside here.
In line with the answer given by Denis de Bernardy..
If you want id to be returned afterwards as well and want to insert more things into Table2:
with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val, val2, val3)
SELECT id, 'val2value', 'val3value'
FROM rows
RETURNING val
Example using std::string
find method:
#include <iostream>
#include <string>
int main (){
std::string str ("There are two needles in this haystack with needles.");
std::string str2 ("needle");
size_t found = str.find(str2);
if(found!=std::string::npos){
std::cout << "first 'needle' found at: " << found << '\n';
}
return 0;
}
Result:
first 'needle' found at: 14.
Steps for adding external jars in IntelliJ IDEA:
You should convert the string to an enumeration value before comparing.
Enum.TryParse("Retailer", out AccountType accountType);
Then
if (userProfile?.AccountType == accountType)
{

The accepted answer saved me (thanks, Bill!!!), but I ran into another related issue, just wanted to provide some details on my experience -
After upgrading to MySQL 8.0.11, I experienced the same problem as the OP when using PHP's mysqli_connect()
function. In my MySQL directory (in my case, usr/local/mysql
), I created the my.cnf
file, added the content in the accepted answer, then restarted the MySQL server. However, this produced a new error:
mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
I added the line default_authentication_plugin = mysql_native_password
, so my.cnf
now looked like:
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8
default_authentication_plugin = mysql_native_password
and I was good to go!

Port Access
Firewalls and other security tools may prevent RabbitMQ from binding to a port. When that happens, RabbitMQ will fail to start. Make sure the following ports can be opened:
4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools
5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
25672: used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). See networking guide for details.
15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)
61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)
1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled
15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)
15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)

It is because you haven't qualified Cells(1, 1)
with a worksheet object, and the same holds true for Cells(10, 2)
. For the code to work, it should look something like this:
Dim ws As Worksheet
Set ws = Sheets("SheetName")
Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents
Alternately:
With Sheets("SheetName")
Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With
EDIT: The Range object will inherit the worksheet from the Cells objects when the code is run from a standard module or userform. If you are running the code from a worksheet code module, you will need to qualify Range
also, like so:
ws.Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents
or
With Sheets("SheetName")
.Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With
Assuming your server side script doesn't set the proper Content-Type: application/json
response header you will need to indicate to jQuery that this is JSON by using the dataType: 'json'
parameter.
Then you could use the $.each()
function to loop through the data:
$.ajax({
type: 'GET',
url: 'http://example/functions.php',
data: { get_param: 'value' },
dataType: 'json',
success: function (data) {
$.each(data, function(index, element) {
$('body').append($('<div>', {
text: element.name
}));
});
}
});
or use the $.getJSON
method:
$.getJSON('/functions.php', { get_param: 'value' }, function(data) {
$.each(data, function(index, element) {
$('body').append($('<div>', {
text: element.name
}));
});
});
The default value of error_reporting flag is E_ALL & ~E_NOTICE if not set in php.ini. But in some installation (particularly installations targeting development environments) has E_ALL | E_STRICT set as value of this flag (this is the recommended value during development). In some cases, specially when you'll want to run some open source projects, that was developed prior to PHP 5.3 era and not yet updated with best practices defined by PHP 5.3, in your development environment, you'll probably run into getting some messages like you are getting. The best way to cope up on this situation, is to set only E_ALL as the value of error_reporting flag, either in php.ini or in code (probably in a front-controller like index.php in web-root as follows:
if(defined('E_STRICT')){
error_reporting(E_ALL);
}
Near the top of the code with the Public Workshop(), I am assumeing this bit,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
suitButton = new JCheckBox("Denim Jeans");
suitButton.setMnemonic(KeyEvent.VK_U);
should maybe be,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
denimjeansButton = new JCheckBox("Denim Jeans");
denimjeansButton.setMnemonic(KeyEvent.VK_U);

Here is another fancy way of doing this:
$ ls | grep .java | xargs -I {} javac {} ; jar -cf myJar.jar *.class
Which will grab all the .java files ( ls | grep .java
) from your current directory and compile them into .class (xargs -I {} javac {}
) and then create the jar file from the previously compiled classes (jar -cf myJar.jar *.class
).
JS does not have a sleep function, it has setTimeout() or setInterval() functions.
If you can move the code that you need to run after the pause into the setTimeout()
callback, you can do something like this:
//code before the pause
setTimeout(function(){
//do what you need here
}, 2000);
see example here : http://jsfiddle.net/9LZQp/
This won't halt the execution of your script, but due to the fact that setTimeout()
is an asynchronous function, this code
console.log("HELLO");
setTimeout(function(){
console.log("THIS IS");
}, 2000);
console.log("DOG");
will print this in the console:
HELLO
DOG
THIS IS
(note that DOG is printed before THIS IS)
You can use the following code to simulate a sleep for short periods of time:
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
now, if you want to sleep for 1 second, just use:
sleep(1000);
example: http://jsfiddle.net/HrJku/1/
please note that this code will keep your script busy for n milliseconds. This will not only stop execution of Javascript on your page, but depending on the browser implementation, may possibly make the page completely unresponsive, and possibly make the entire browser unresponsive. In other words this is almost always the wrong thing to do.
Change
var trainindIdArray = traingIds.split(',');
to
var trainindIdArray = traingIds.replace("[","").replace("]","").split(',');
That will basically remove [
and ]
and then split the string
This is probably simpler than you're thinking:
int w = WIDTH_PX, h = HEIGHT_PX;
Bitmap.Config conf = Bitmap.Config.ARGB_8888; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);
// ready to draw on that bitmap through that canvas
Here's a series of tutorials I've found on the topic: Drawing with Canvas Series

How about this one:
Garbage collectors actually hurt programmers' productivity and make resource leaks harder to find and fix
Note that I am talking about resouces in general, and not only memory.
The second parameter of the callback function passed to each() will contain the actual DOM element and not a jQuery wrapper object. You can call the getAttribute() method of the element:
$('#category_sorting_form_save').click(function() {
var elements = $("#category_sorting_elements > div");
$.each(elements, function(key, value) {
console.info(key, ": ", value);
console.info("cat_id: ", value.getAttribute('cat_id'));
});
});
Or wrap the element in a jQuery object yourself:
$('#category_sorting_form_save').click(function() {
var elements = $("#category_sorting_elements > div");
$.each(elements, function(key, value) {
console.info(key, ": ", value);
console.info("cat_id: ", $(value).attr('cat_id'));
});
});
Or simply use $(this)
:
$('#category_sorting_form_save').click(function() {
var elements = $("#category_sorting_elements > div");
$.each(elements, function() {
console.info("cat_id: ", $(this).attr('cat_id'));
});
});
you can add static
to make possible the initialization of this class member variable.
static const int i = 100;
However, this is not always a good practice to use inside class declaration, because all objects instacied from that class will shares the same static variable which is stored in internal memory outside of the scope memory of instantiated objects.
You can add a random (or datetime string) as query string to the url that points to your script. Like so:
<script type="text/javascript" src="test.js?q=123"></script>
Every time you refresh the page you need to make sure the value of 'q' is changed.
define "display it dynamically" ? that implies the table is being built via javascript and some sort of Ajax-y update .. if you just want to build the table using PHP that's really not what I would call 'dynamic'
When I wanted to run a chromium-browser on Ubuntu precise (glibc-2.15), I got the (typical) message "...libc.so.6: version `GLIBC_2.19' not found...". I considered the fact, that files are not needed permamently, but only for start. So I collected the files needed for the browser and sudo and created a mini-glibc-2.19- environment, started the browser and then copied the original files back again. The needed files are in RAM and the original glibc is the same.
as root
the files (*-2.15.so) already exist

Use the flex-grow
property to make a flex item consume free space on the main axis.
This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.
A common example is flex-grow: 1
or, using the shorthand property, flex: 1
.
Hence, instead of width: 96%
on your div, use flex: 1
.
You wrote:
So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.
The squashing of the fixed-width div is related to another flex property: flex-shrink
By default, flex items are set to flex-shrink: 1
which enables them to shrink in order to prevent overflow of the container.
To disable this feature use flex-shrink: 0
.
For more details see The flex-shrink
factor section in the answer here:

This basically has to do with the hardware architecture (i.e. RAM and caches).
If you don't use synchronized
together with wait()
or notify()
, another thread could enter the same block instead of waiting for the monitor to enter it. Moreover, when e.g. accessing an array without a synchronized block, another thread may not see the changement to it...actually another thread will not see any changements to it when it already has a copy of the array in the x-level cache (a.k.a. 1st/2nd/3rd-level caches) of the thread handling CPU core.
But synchronized blocks are only one side of the medal: If you actually access an object within a synchronized context from a non-synchronized context, the object still won't be synchronized even within a synchronized block, because it holds an own copy of the object in its cache. I wrote about this issues here: https://stackoverflow.com/a/21462631 and When a lock holds a non-final object, can the object's reference still be changed by another thread?
Furthermore, I'm convinced that the x-level caches are responsible for most non-reproducible runtime errors. That's because the developers usually don't learn the low-level stuff, like how CPU's work or how the memory hierarchy affects the running of applications: http://en.wikipedia.org/wiki/Memory_hierarchy
It remains a riddle why programming classes don't start with memory hierarchy and CPU architecture first. "Hello world" won't help here. ;)
Not at the moment and you would be lucky to get Jython to work soon. If you're planning to start your development now you would be better off with just sticking to Java for now on.

As TokenMacGuy says, you should use thread.is_alive()
to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:
for t in my_threads:
if not t.is_alive():
# get results from thread
t.handled = True
my_threads = [t for t in my_threads if not t.handled]
This avoids the problem of removing items from a list while iterating over it.
Script snip below creates a pause sub that displayes the pause text in a string and waits for the Enter key. z can be anything. Great if multilple user intervention required pauses are needed. I just keep it in my standard script template.
Pause("Press Enter to continue")
Sub Pause(strPause)
WScript.Echo (strPause)
z = WScript.StdIn.Read(1)
End Sub
To get rid of lazy initialization exception you should not call for lazy collection when you operate with detached object.
From my opinion, best approach is to use DTO, and not entity. In this case you can explicitly set fields which you want to use. As usual it's enough. No need to worry that something like jackson ObjectMapper
, or hashCode
generated by Lombok will call your methods implicitly.
For some specific cases you can use @EntityGrpaph
annotation, which allow you to make eager
load even if you have fetchType=lazy
in your entity.
Here's more specific examples of both:
Serialization Example:
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
typedef struct {
char value[11];
} SerializedInt32;
SerializedInt32 SerializeInt32(int32_t x)
{
SerializedInt32 result;
itoa(x, result.value, 10);
return result;
}
int32_t DeserializeInt32(SerializedInt32 x)
{
int32_t result;
result = atoi(x.value);
return result;
}
int main(int argc, char **argv)
{
int x;
SerializedInt32 data;
int32_t result;
x = -268435455;
data = SerializeInt32(x);
result = DeserializeInt32(data);
printf("x = %s.\n", data.value);
return result;
}
In serialization, data is flattened in a way that can be stored and unflattened later.
Marshalling Demo:
(MarshalDemoLib.cpp)
#include <iostream>
#include <string>
extern "C"
__declspec(dllexport)
void *StdCoutStdString(void *s)
{
std::string *str = (std::string *)s;
std::cout << *str;
}
extern "C"
__declspec(dllexport)
void *MarshalCStringToStdString(char *s)
{
std::string *str(new std::string(s));
std::cout << "string was successfully constructed.\n";
return str;
}
extern "C"
__declspec(dllexport)
void DestroyStdString(void *s)
{
std::string *str((std::string *)s);
delete str;
std::cout << "string was successfully destroyed.\n";
}
(MarshalDemo.c)
#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
int main(int argc, char **argv)
{
void *myStdString;
LoadLibrary("MarshalDemoLib");
myStdString = ((void *(*)(char *))GetProcAddress (
GetModuleHandleA("MarshalDemoLib"),
"MarshalCStringToStdString"
))("Hello, World!\n");
((void (*)(void *))GetProcAddress (
GetModuleHandleA("MarshalDemoLib"),
"StdCoutStdString"
))(myStdString);
((void (*)(void *))GetProcAddress (
GetModuleHandleA("MarshalDemoLib"),
"DestroyStdString"
))(myStdString);
}
In marshaling, data does not necessarily need to be flattened, but it needs to be transformed to another alternative representation. all casting is marshaling, but not all marshaling is casting.
Marshaling doesn't require dynamic allocation to be involved, it can also just be transformation between structs. For example, you might have a pair, but the function expects the pair's first and second elements to be other way around; you casting/memcpy one pair to another won't do the job because fst and snd will get flipped.
#include <stdio.h>
typedef struct {
int fst;
int snd;
} pair1;
typedef struct {
int snd;
int fst;
} pair2;
void pair2_dump(pair2 p)
{
printf("%d %d\n", p.fst, p.snd);
}
pair2 marshal_pair1_to_pair2(pair1 p)
{
pair2 result;
result.fst = p.fst;
result.snd = p.snd;
return result;
}
pair1 given = {3, 7};
int main(int argc, char **argv)
{
pair2_dump(marshal_pair1_to_pair2(given));
return 0;
}
The concept of marshaling becomes especially important when you start dealing with tagged unions of many types. For example, you might find it difficult to get a JavaScript engine to print a "c string" for you, but you can ask it to print a wrapped c string for you. Or if you want to print a string from JavaScript runtime in a Lua or Python runtime. They are all strings, but often won't get along without marshaling.
An annoyance I had recently was that JScript arrays marshal to C# as "__ComObject", and has no documented way to play with this object. I can find the address of where it is, but I really don't know anything else about it, so the only way to really figure it out is to poke at it in any way possible and hopefully find useful information about it. So it becomes easier to create a new object with a friendlier interface like Scripting.Dictionary, copy the data from the JScript array object into it, and pass that object to C# instead of JScript's default array.
test.js:
var x = new ActiveXObject("Dmitry.YetAnotherTestObject.YetAnotherTestObject");
x.send([1, 2, 3, 4]);
YetAnotherTestObject.cs
using System;
using System.Runtime.InteropServices;
namespace Dmitry.YetAnotherTestObject
{
[Guid("C612BD9B-74E0-4176-AAB8-C53EB24C2B29"), ComVisible(true)]
public class YetAnotherTestObject
{
public void send(object x)
{
System.Console.WriteLine(x.GetType().Name);
}
}
}
above prints "__ComObject", which is somewhat of a black box from the point of view of C#.
Another interesting concept is that you might have the understanding how to write code, and a computer that knows how to execute instructions, so as a programmer, you are effectively marshaling the concept of what you want the computer to do from your brain to the program image. If we had good enough marshallers, we could just think of what we want to do/change, and the program would change that way without typing on the keyboard. So, if you could have a way to store all the physical changes in your brain for the few seconds where you really want to write a semicolon, you could marshal that data into a signal to print a semicolon, but that's an extreme.
Yes, Json.Net is what you need. You basically want to deserialize a Json string into an array of objects
.
See their examples:
string myJsonString = @"{
"Name": "Apple",
"Expiry": "\/Date(1230375600000+1300)\/",
"Price": 3.99,
"Sizes": [
"Small",
"Medium",
"Large"
]
}";
// Deserializes the string into a Product object
Product myProduct = JsonConvert.DeserializeObject<Product>(myJsonString);
Siddharth's answer is nice, but relies on globally-scoped variables. There's a better, more OOP-friendly way.
A UserForm is a class module like any other - the only difference is that it has a hidden VB_PredeclaredId
attribute set to True
, which makes VB create a global-scope object variable named after the class - that's how you can write UserForm1.Show
without creating a new instance of the class.
Step away from this, and treat your form as an object instead - expose Property Get
members and abstract away the form's controls - the calling code doesn't care about controls anyway:
Option Explicit
Private cancelling As Boolean
Public Property Get UserId() As String
UserId = txtUserId.Text
End Property
Public Property Get Password() As String
Password = txtPassword.Text
End Property
Public Property Get IsCancelled() As Boolean
IsCancelled = cancelling
End Property
Private Sub OkButton_Click()
Me.Hide
End Sub
Private Sub CancelButton_Click()
cancelling = True
Me.Hide
End Sub
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = VbQueryClose.vbFormControlMenu Then
cancelling = True
Cancel = True
Me.Hide
End If
End Sub
Now the calling code can do this (assuming the UserForm was named LoginPrompt
):
With New LoginPrompt
.Show vbModal
If .IsCancelled Then Exit Sub
DoSomething .UserId, .Password
End With
Where DoSomething
would be some procedure that requires the two string parameters:
Private Sub DoSomething(ByVal uid As String, ByVal pwd As String)
'work with the parameter values, regardless of where they came from
End Sub
Another problem that may arise relating to receiving an unauthorized is related to the providers used in the authentication setting from IIS. In My case I was experience that problem If I set the Windows Authentication provider as "Negotiate". After I selected "NTLM" option the access was granted.

In first statement you define variable, which common for all of the objects (class static field).
In the second statement you define variable, which belongs to each created object (a lot of copies).
In your case you should use the first one.

[I mentioned this in response to the selected answer, but it was suggested to make it more prominent as an answer of its own]
It should be noted that
ENV PATH="/opt/gtk/bin:${PATH}"
may not be the same as
ENV PATH="/opt/gtk/bin:$PATH"
The former, with curly brackets, might provide you with the host's PATH. The documentation doesn't suggest this would be the case, but I have observed that it is. This is simple to check just do RUN echo $PATH
and compare it to RUN echo ${PATH}

I had the same issue to remove old fragments. I ended up clearing the layout that contained the fragments.
LinearLayout layout = (LinearLayout) a.findViewById(R.id.layoutDeviceList);
layout.removeAllViewsInLayout();
FragmentTransaction ft = getFragmentManager().beginTransaction();

Easiest solution
$('.offer').click(function(){
var cc = $(this).attr('checked') == undefined ? false : true;
$(this).find(':checkbox').attr('checked',cc);
});
Any int other than zero is true; false is zero. That way code like this continues to work as expected:
int done = 0; // `int` could be `bool` just as well
while (!done)
{
// ...
done = OS_SUCCESS_CODE == some_system_call ();
}
IMO, bool
is an overrated type, perhaps a carry over from other languages. int
works just fine as a boolean type.
You need to install it in a directory in your home folder, and somehow manipulate the PYTHONPATH so that directory is included.
The best and easiest is to use virtualenv. But that requires installation, causing a catch 22. :) But check if virtualenv is installed. If it is installed you can do this:
$ cd /tmp
$ virtualenv foo
$ cd foo
$ ./bin/python
Then you can just run the installation as usual, with /tmp/foo/python setup.py install. (Obviously you need to make the virtual environment in your a folder in your home directory, not in /tmp/foo. ;) )
If there is no virtualenv, you can install your own local Python. But that may not be allowed either. Then you can install the package in a local directory for packages:
$ wget http://pypi.python.org/packages/source/s/six/six-1.0b1.tar.gz#md5=cbfcc64af1f27162a6a6b5510e262c9d
$ tar xvf six-1.0b1.tar.gz
$ cd six-1.0b1/
$ pythonX.X setup.py install --install-dir=/tmp/frotz
Now you need to add /tmp/frotz/pythonX.X/site-packages
to your PYTHONPATH, and you should be up and running!
If you are reading the dataframe from a file (say CSV or Excel) then use :
df.read_csv(path , na_filter=False)
df.read_excel(path , na_filter=False)
This will automatically consider the empty fields as empty strings ''
If you already have the dataframe
df = df.replace(np.nan, '', regex=True)
df = df.fillna('')
If you need a permanent solution for keeping Python cache files out of your project directories:
Starting with Python 3.8 you can use the environment variable PYTHONPYCACHEPREFIX
to define a cache directory for Python.
From the Python docs:
If this is set, Python will write .pyc files in a mirror directory tree at this path, instead of in pycache directories within the source tree. This is equivalent to specifying the -X pycache_prefix=PATH option.
Example
If you add the following line to your ./profile
in Linux:
export PYTHONPYCACHEPREFIX="$HOME/.cache/cpython/"
Python won't create the annoying __pycache__
directories in your project directory, instead it will put all of them under ~/.cache/cpython/
Go to the download page and download the Windows x86
version with filename jdk-7-windows-i586.exe
.
force it with -l
sudo umount -l ${HOME}/mount_dir
Always have handy the un-minified CSS for bootstrap so you can see what styles they have on their components, then create a CSS file AFTER it, if you don't use LESS and over-write their mixins or whatever
This is the default modal css for 768px and up:
@media (min-width: 768px) {
.modal-dialog {
width: 600px;
margin: 30px auto;
}
...
}
They have a class modal-lg
for larger widths
@media (min-width: 992px) {
.modal-lg {
width: 900px;
}
}
If you need something twice the 600px size, and something fluid, do something like this in your CSS after the Bootstrap css and assign that class to the modal-dialog.
@media (min-width: 768px) {
.modal-xl {
width: 90%;
max-width:1200px;
}
}
HTML
<div class="modal-dialog modal-xl">

You might have pressed 0
(also used for insert, shortcut INS
) key, which is on the right side of your right scroll button. To solve the problem, just press it again or double click on 'overwrite'.
You say you have a database on PhpMyAdmin, so you are using MySQL. PHP provides functions for connecting to a MySQL database.
$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');
$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);
echo "<table>"; // start a table tag in the HTML
while($row = mysql_fetch_array($result)){ //Creates a loop to loop through results
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['age'] . "</td></tr>"; //$row['index'] the index here is a field name
}
echo "</table>"; //Close the table in HTML
mysql_close(); //Make sure to close out the database connection
In the while loop (which runs every time we encounter a result row), we echo which creates a new table row. I also add a to contain the fields.
This is a very basic template. You see the other answers using mysqli_connect instead of mysql_connect. mysqli stands for mysql improved. It offers a better range of features. You notice it is also a little bit more complex. It depends on what you need.
I used the page-checkout.php template to change the header for my cart page. I renamed it to page-cart.php in my /wp-content/themes/childtheme/woocommerce/. This gives you more control over the wrapping html, header and footer.
if it is a RSA key
openssl rsa -pubout -in my_rsa_key.pem
if you need it in a format for openssh , please see Use RSA private key to generate public key?
Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.
Class-based decorators use __call__
to reference the wrapped function. E.g.:
class Deco(object):
def __init__(self,f):
self.f = f
def __call__(self, *args, **kwargs):
print args
print kwargs
self.f(*args, **kwargs)
There is a good description of the various options here at Artima.com
It turns out the best solution for me here was to just reformat the drive. Once reformatted all these problems were no longer problems.
Like this:
#include <vector>
// ...
std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));
(Pre-C++11 you need to leave whitespace between the angled brackets.)
One thing that might not always be obvious to some is that a cross join with an empty table (or result set) results in empty table (M x N; hence M x 0 = 0)
A full outer join will always have rows unless both M and N are 0.

You can use the UpdateProgress control:
This error happened to me too as the original repository creator had left the company, which meant their account was deleted from the github team.
git remote set-url origin https://github.com/<user_name>/<repo_name>.git
And then
git pull origin develop
or whatever git command you wanted to execute should prompt you for a login and continue as normal.
In the same vein as martineau's response, the best solution is often not to check. For example, the code
if x in d:
foo = d[x]
else:
foo = bar
is normally written
foo = d.get(x, bar)
which is shorter and more directly speaks to what you mean.
Another common case is something like
if x not in d:
d[x] = []
d[x].append(foo)
which can be rewritten
d.setdefault(x, []).append(foo)
or rewritten even better by using a collections.defaultdict(list)
for d
and writing
d[x].append(foo)
In the following line.
temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();
You are calling First but the collection returned from db.Responses.Where is empty.
To make the images flexible, simply add
max-width:100%
andheight:auto
. Imagemax-width:100%
andheight:auto
works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to addwidth:auto\9
for IE8.source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries
for example :
img {
max-width: 100%;
height: auto;
width: auto\9; /* ie8 */
}
and then any images you add simply using the img tag will be flexible
JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).
You can try something like this:
Inside customview constructor:
mContext = context;
Next inside customview you can call:
((MainActivity) mContext).updateText( text );
Inside MainAcivity
define:
public void updateText(final String text) {
TextView txtView = (TextView) findViewById(R.id.text);
txtView.setText(text);
}
It works for me.
It is Safari specific, at least at time of writing, being introduced in Safari 9.0. From the "What's new in Safari?" documentation for Safari 9.0:
Viewport Changes
Viewport meta tags using
"width=device-width"
cause the page to scale down to fit content that overflows the viewport bounds. You can override this behavior by adding"shrink-to-fit=no"
to your meta tag as shown below. The added value will prevent the page from scaling to fit the viewport.
<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">
In short, adding this to the viewport meta tag restores pre-Safari 9.0 behaviour.
Here's a worked visual example which shows the difference upon loading the page in the two configurations.
The red section is the width of the viewport and the blue section is positioned outside the initial viewport (eg left: 100vw
). Note how in the first example the page is zoomed to fit when shrink-to-fit=no
is omitted (thus showing the out-of-viewport content) and the blue content remains off screen in the latter example.
The code for this example can be found at https://codepen.io/davidjb/pen/ENGqpv.
Foreground needs a Brush, so you can use
textBlock.Foreground = Brushes.Navy;
If you want to use the color from RGB or ARGB then
textBlock.Foreground = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(100, 255, 125, 35));
or
textBlock.Foreground = new System.Windows.Media.SolidColorBrush(Colors.Navy);
To get the Color from Hex
textBlock.Foreground = new System.Windows.Media.SolidColorBrush((Color)ColorConverter.ConvertFromString("#FFDFD991"));

Wait and notify method always called on object so whether it may be Thread object or simple object (which does not extends Thread class) Given Example will clear your all the doubts.
I have called wait and notify on class ObjB and that is the Thread class so we can say that wait and notify are called on any object.
public class ThreadA {
public static void main(String[] args){
ObjB b = new ObjB();
Threadc c = new Threadc(b);
ThreadD d = new ThreadD(b);
d.setPriority(5);
c.setPriority(1);
d.start();
c.start();
}
}
class ObjB {
int total;
int count(){
for(int i=0; i<100 ; i++){
total += i;
}
return total;
}}
class Threadc extends Thread{
ObjB b;
Threadc(ObjB objB){
b= objB;
}
int total;
@Override
public void run(){
System.out.print("Thread C run method");
synchronized(b){
total = b.count();
System.out.print("Thread C notified called ");
b.notify();
}
}
}
class ThreadD extends Thread{
ObjB b;
ThreadD(ObjB objB){
b= objB;
}
int total;
@Override
public void run(){
System.out.print("Thread D run method");
synchronized(b){
System.out.println("Waiting for b to complete...");
try {
b.wait();
System.out.print("Thread C B value is" + b.total);
}
catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
Since we now have inline javascript snippets I might as well add an interactive example of pre and pos increment. It's not C++ but the concept stays the same.
let A = 1;_x000D_
let B = 1;_x000D_
_x000D_
console.log('A++ === 2', A++ === 2);_x000D_
console.log('++B === 2', ++B === 2);
_x000D_
I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.
def remove_chars(line):
line7=line[7].translate(None,'abcd')
return line[:7]+[line7]+line[8:]
line= ['ad','da','sdf','asd',
'3424','342sfas','asdfaf','sdfa',
'afase']
print line[7]
line = remove_chars(line)
print line[7]
Use HttpUrlConnection by calling openConnection()
on your URL object.
getResponseCode() will give you the HTTP response once you've read from the connection.
e.g.
URL u = new URL("http://www.example.com/");
HttpURLConnection huc = (HttpURLConnection)u.openConnection();
huc.setRequestMethod("GET");
huc.connect() ;
OutputStream os = huc.getOutputStream();
int code = huc.getResponseCode();

You may corrupt the file during copy/transfer.
Are you using maven? If you are copying keystore file with "filter=true", you may corrupt the file.
Please check the file size.
If you use "hg remove b"
against a file with "A" status, which means it has been added but not commited, Mercurial will respond:
not removing b: file has been marked for add (use forget to undo)
This response is a very clear explication of the difference between remove and forget.
My understanding is that "hg forget"
is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove"
is for taking out a committed file from version control.
This thread has a example for using hg remove
against files of 7 different types of status.
Here is a simple implementation that handles an unequal number of classes in the predicted and actual labels (see examples 3 and 4). I hope this helps!
For folks just learning this, here's a quick review. The labels for the columns indicate the predicted class, and the labels for the rows indicate the correct class. In example 1, we have [3 1] on the top row. Again, rows indicate truth, so this means that the correct label is "0" and there are 4 examples with ground truth label of "0". Columns indicate predictions, so we have 3/4 of the samples correctly labeled as "0", but 1/4 was incorrectly labeled as a "1".
def confusion_matrix(actual, predicted):
classes = np.unique(np.concatenate((actual,predicted)))
confusion_mtx = np.empty((len(classes),len(classes)),dtype=np.int)
for i,a in enumerate(classes):
for j,p in enumerate(classes):
confusion_mtx[i,j] = np.where((actual==a)*(predicted==p))[0].shape[0]
return confusion_mtx
Example 1:
actual = np.array([1,1,1,1,0,0,0,0])
predicted = np.array([1,1,1,1,0,0,0,1])
confusion_matrix(actual,predicted)
0 1
0 3 1
1 0 4
Example 2:
actual = np.array(["a","a","a","a","b","b","b","b"])
predicted = np.array(["a","a","a","a","b","b","b","a"])
confusion_matrix(actual,predicted)
0 1
0 4 0
1 1 3
Example 3:
actual = np.array(["a","a","a","a","b","b","b","b"])
predicted = np.array(["a","a","a","a","b","b","b","z"]) # <-- notice the 3rd class, "z"
confusion_matrix(actual,predicted)
0 1 2
0 4 0 0
1 0 3 1
2 0 0 0
Example 4:
actual = np.array(["a","a","a","x","x","b","b","b"]) # <-- notice the 4th class, "x"
predicted = np.array(["a","a","a","a","b","b","b","z"])
confusion_matrix(actual,predicted)
0 1 2 3
0 3 0 0 0
1 0 2 0 1
2 1 1 0 0
3 0 0 0 0
This should be an answer
str2.equals( str )
If you want to ignore case
str2.equalsIgnoreCase( str )
Another solution is to use getDocumentById
and insertAdjacentHTML
.
Code:
function addRow() {
const div = document.getElementById('content');
div.insertAdjacentHTML('afterbegin', 'PUT_HTML_HERE');
}
Check here, for more details: Element.insertAdjacentHTML()
a simple way to do this:
try {
list.get( index );
}
catch ( IndexOutOfBoundsException e ) {
if(list.isEmpty() || index >= list.size()){
// Adding new item to list.
}
}
Have you added the google maven endpoint?
Important: The support libraries are now available through Google's Maven repository. You do not need to download the support repository from the SDK Manager. For more information, see Support Library Setup.
Add the endpoint to your build.gradle file:
allprojects {
repositories {
jcenter()
maven {
url 'https://maven.google.com'
}
}
}
Which can be replaced by the shortcut google()
since Android Gradle v3:
allprojects {
repositories {
jcenter()
google()
}
}
If you already have any maven url inside repositories
, you can add the reference after them, i.e.:
allprojects {
repositories {
jcenter()
maven {
url 'https://jitpack.io'
}
maven {
url 'https://maven.google.com'
}
}
}
If performance doesn't matter, you could serialize them and compare the results:
var serializer = new XmlSerializer(typeof(TheObjectType));
StringWriter serialized1 = new StringWriter(), serialized2 = new StringWriter();
serializer.Serialize(serialized1, obj1);
serializer.Serialize(serialized2, obj2);
bool areEqual = serialized1.ToString() == serialized2.ToString();
use long startTime=System.currentTimeMillis()
for start time, at the top of the loop
put long endTime= System.currentTimeMillis();
outside the end of the loop. You'll have to subtract the values to get the runtime in milliseconds.
If you want time in nanoseconds, check out System.nanoTime()
In ES5 there is no efficient way to iterate over a sparse array without using the length property. In ES6 you can use for...of
. Take this examples:
'use strict';_x000D_
_x000D_
var arr = ['one', 'two', undefined, 3, 4],_x000D_
output;_x000D_
_x000D_
arr[6] = 'five';_x000D_
_x000D_
output = '';_x000D_
arr.forEach(function (val) {_x000D_
output += val + ' ';_x000D_
});_x000D_
console.log(output);_x000D_
_x000D_
output = '';_x000D_
for (var i = 0; i < arr.length; i++) {_x000D_
output += arr[i] + ' ';_x000D_
}_x000D_
console.log(output);_x000D_
_x000D_
output = '';_x000D_
for (var val of arr) {_x000D_
output += val + ' ';_x000D_
};_x000D_
console.log(output);
_x000D_
<!-- results pane console output; see http://meta.stackexchange.com/a/242491 -->_x000D_
<script src="//gh-canon.github.io/stack-snippet-console/console.min.js"></script>

All array methods which you can use to iterate safely over dense arrays use the length
property of an object created by calling ToObject
internaly. See for instance the algorithm used in the forEach
method: http://www.ecma-international.org/ecma-262/5.1/#sec-15.4.4.18
However in es6, you can use for...of
safely for iterating over sparse arrays.

I think what you are looking for is
Request.QueryString["QueryStringName"]
and you can access it on views by adding @
now look at my example,,, I generated a Url with QueryString
var listURL = '@Url.RouteUrl(new { controller = "Sector", action = "List" , name = Request.QueryString["name"]})';
the listURL value is /Sector/List?name=value'
and when queryString
is empty
listURL value is /Sector/List
Ok, here's a basic join query that gets the correct records:
int[] selectedRolesArr = GetSelectedRoles();
if( selectedRolesArr != null && selectedRolesArr.Length > 0 )
{
//this join version requires the use of distinct to prevent muliple records
//being returned for users with more than one company role.
IQueryable retVal = (from u in context.Users
join c in context.CompanyRolesToUsers
on u.Id equals c.UserId
where u.LastName.Contains( "fra" ) &&
selectedRolesArr.Contains( c.CompanyRoleId )
select u).Distinct();
}
But here's the code that most easily integrates with the algorithm that we already had in place:
int[] selectedRolesArr = GetSelectedRoles();
if ( useAnd )
{
predicateAnd = predicateAnd.And( u => (from c in context.CompanyRolesToUsers
where selectedRolesArr.Contains(c.CompanyRoleId)
select c.UserId).Contains(u.Id));
}
else
{
predicateOr = predicateOr.Or( u => (from c in context.CompanyRolesToUsers
where selectedRolesArr.Contains(c.CompanyRoleId)
select c.UserId).Contains(u.Id) );
}
which is thanks to a poster at the LINQtoSQL forum
For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error
func databaseURL() -> NSURL? {
let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
// This is where the database should be in the documents directory
let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")
if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
// The file already exists, so just return the URL
return finalDatabaseURL
} else {
// Copy the initial file from the application bundle to the documents directory
if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
do {
try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
} catch let error as NSError {// Handle the error
print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
}
} else {
print("Couldn't find initial database in the bundle!")
}
}
} else {
print("Couldn't get documents directory!")
}
return nil
}
Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable
func databaseURL() -> NSURL? {
let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
// If array of path is empty the document folder not found
guard urls.count != 0 else {
return nil
}
let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
// Check if file is exists in bundle folder
if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
// if exist we will copy it
do {
try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
} catch let error as NSError { // Handle the error
print("File copy failed! Error:\(error.localizedDescription)")
}
} else {
print("Our file not exist in bundle folder")
return nil
}
return finalDatabaseURL
}
return finalDatabaseURL
}
You probably missed package declaration
package my.demo.service;

this is a special case of adding a new column to a pandas dataframe. Here, I am adding a new feature/column based on an existing column data of the dataframe.
so, let our dataFrame has columns 'feature_1', 'feature_2', 'probability_score' and we have to add a new_column 'predicted_class' based on data in column 'probability_score'.
I will use map() function from python and also define a function of my own which will implement the logic on how to give a particular class_label to every row in my dataFrame.
data = pd.read_csv('data.csv')
def myFunction(x):
//implement your logic here
if so and so:
return a
return b
variable_1 = data['probability_score']
predicted_class = variable_1.map(myFunction)
data['predicted_class'] = predicted_class
// check dataFrame, new column is included based on an existing column data for each row
data.head()
The term you should be googling is "authoritative," not "definitive".
On Linux or Mac you can use the commands whois
, dig
, host
, nslookup
or several others. nslookup
might also work on Windows.
An example:
$ whois stackoverflow.com
[...]
Domain servers in listed order:
NS51.DOMAINCONTROL.COM
NS52.DOMAINCONTROL.COM
As for the extra credit: Yes, it is possible.
aryeh is definitely wrong, as his suggestion usually will only give you the IP address for the hostname. If you use dig
, you have to look for NS records, like so:
dig ns stackoverflow.com
Keep in mind that this may ask your local DNS server and thus may give wrong or out-of-date answers that it has in its cache.
How about:
StringBuilder builder = new StringBuilder();
for(int i=99;i>=0;i--){
builder.append(Integer.toString(i));
}
builder.toString();
OR
StringBuilder builder = new StringBuilder();
for(int i=0;i<100;i++){
builder.insert(0, Integer.toString(i));
}
builder.toString();
But with this, you are making the operation O(N^2) instead of O(N).
Snippet from java docs:
Inserts the string representation of the Object argument into this character sequence. The overall effect is exactly as if the second argument were converted to a string by the method
String.valueOf(Object)
, and the characters of that string were then inserted into this character sequence at the indicated offset.
Try this:
<script type="text/javascript">
$(document).ready
(
function ()
{
var regExp = /franky/g;
var testString = "something.com/frankyssssddsdfjsdflk?franky";//Inyour case it would be window.location;
if(regExp.test(testString)) // This doesn't work, any suggestions.
{
alert("your url contains the name franky");
}
}
);
</script>
Had the same problem on another server, but realized that locales are messed.
export LC_ALL="en_US.UTF-8"

Maybe a simple loop for chars to replace:
a = '&#'
to_replace = ['&', '#']
for char in to_replace:
a = a.replace(char, "\\"+char)
print(a)
>>> \&\#
Try This
$( "#email,#confirmEmail " ).on( "copy cut paste drop", function() {
return false;
});
This works for me (Chrome 86):
function download(content, mimeType, filename){
var a = document.createElement('a')
var blob = new Blob([content], {type: mimeType})
var url = URL.createObjectURL(blob)
a.setAttribute('href', url)
a.setAttribute('download', filename)
a.click()
}

Extending User1648825's nice simple answer (I can't comment and my edit was rejected):
@Value("${spring.profiles.active}")
private String activeProfile;
This may throw an IllegalArgumentException if no profiles are set (I get a null value). This may be a Good Thing if you need it to be set; if not use the 'default' syntax for @Value, ie:
@Value("${spring.profiles.active:Unknown}")
private String activeProfile;
...activeProfile now contains 'Unknown' if spring.profiles.active could not be resolved

I use ruamel.yaml. Details & debate here.
from ruamel import yaml
with open(filename, 'r') as fp:
read_data = yaml.load(fp)
Usage of ruamel.yaml is compatible (with some simple solvable problems) with old usages of PyYAML and as it is stated in link I provided, use
from ruamel import yaml
instead of
import yaml
and it will fix most of your problems.
EDIT: PyYAML is not dead as it turns out, it's just maintained in a different place.
It may be because you are not stopping your tomcat service properly. To do that, Open your task manager there you can see a javaw.exe

You might have 10,000 users total, but that's not the same as concurrent users. In this context, concurrent scripts being run.
For example, if your visitor visits index.php, and it makes a database query to get some user details, that request might live for 250ms. You can limit how long those MySQL connections live even further by opening and closing them only when you are querying, instead of leaving it open for the duration of the script.
While it is hard to make any type of formula to predict how many connections would be open at a time, I'd venture the following:
You probably won't have more than 500 active users at any given time with a user base of 10,000 users. Of those 500 concurrent users, there will probably at most be 10-20 concurrent requests being made at a time.
That means, you are really only establishing about 10-20 concurrent requests.
As others mentioned, you have nothing to worry about in that department.
Try this:
//String.Format("{0:HH:mm}", dt); // where dt is a DateTime variable
public static string FormatearHoraA24(DateTime? fechaHora)
{
if (!fechaHora.HasValue)
return "";
return retornar = String.Format("{0:HH:mm}", (DateTime)fechaHora);
}
With TypeScript generics you can do something like this.
class Person {
constructor (public Name : string, public Age: number) {}
}
var list = new Array<Person>();
list.push(new Person("Baby", 1));
list.push(new Person("Toddler", 2));
list.push(new Person("Teen", 14));
list.push(new Person("Adult", 25));
var oldest_person = list.reduce( (a, b) => a.Age > b.Age ? a : b );
alert(oldest_person.Name);
If you want to take advantage of recent Python versions' async features, you can use aioftp (from the same family of libraries and developers as the more popular aiohttp library). Here is a code example taken from their client tutorial:
client = aioftp.Client()
await client.connect("ftp.server.com")
await client.login("user", "pass")
await client.download("tmp/test.py", "foo.py", write_into=True)
Use the "MMMM" format specifier:
string month = dateTime.ToString("MMMM");
I changed the permission of my .ssh/id_rsa (private key) to 604. chmod 700 id_rsa
You can use the JSON stringify
method.
JSON.stringify({x: 5, y: 6}); // '{"x":5,"y":6}' or '{"y":6,"x":5}'
There is pretty good support for this across the board when it comes to browsers, as shown on http://caniuse.com/#search=JSON. You will note, however, that versions of IE earlier than 8 do not support this functionality natively.
If you wish to cater to those users as well you will need a shim. Douglas Crockford has provided his own JSON Parser on github.

The jQuery docs for text()
says
Due to variations in the HTML parsers in different browsers, the text returned may vary in newlines and other white space.
I'd use $td.html()
instead.
This is how it should be:
Code:
$(function(){
$("button").mouseover(function(){
var $p = $("#P44");
$p.stop()
.css("background-color","yellow")
.hide(1500, function() {
$p.css("background-color","red")
.show(1500);
});
});
});
Demo: http://jsfiddle.net/p7w9W/2/
Explanation:
You have to wait for the callback on the animating functions before you switch background color. You should also not use only numeric ID:s, and if you have an ID of your <p>
there you shouldn't include a class in your selector.
I also enhanced your code (caching of the jQuery object, chaining, etc.)
Update: As suggested by VKolev the color is now changing when the item is hidden.
It uses HTML DOM Elements, but not jQuery selector. It can be used like:
var height = document.body.scrollHeight;
There are many ways to do this, one way is:
sqlite3 auction.db
Followed by:
sqlite> .read create.sql
In general, the SQLite project has really fantastic documentation! I know we often reach for Google before the docs, but in SQLite's case, the docs really are technical writing at its best. It's clean, clear, and concise.
The setw manipulator function will be of help here.
MySqlCommand cmd = new MySqlCommand("select * from table where user = '" + user.Text + "'", con);
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
DataSet ds1 = new DataSet();
da.Fill(ds1);
int i = ds1.Tables[0].Rows.Count;
if (i > 0) {
// Exist
}
else {
// Add
}
You can't do this with jQuery, visible="false"
in asp.net means the control isn't rendered into the page. If you want the control to go to the client, you need to do style="display: none;"
so it's actually in the HTML, otherwise there's literally nothing for the client to show, since the element wasn't in the HTML your server sent.
If you remove the visible
attribute and add the style
attribute you can then use jQuery to show it, like this:
$("#elementID").show();
To change visibility
, you need to use .css()
, like this:
$("#elem").css('visibility', 'visible');
Unless you need to have the element occupy page space though, use display: none;
instead of visibility: hidden;
in your CSS, then just do:
$("#elem").show();
The .show()
and .hide()
functions deal with display
instead of visibility
, like most of the jQuery functions :)
in the latest version of angular4 use
import { Observable } from 'rxjs/Rx'
it will import all the required things.
From Oracle 12c R2 you could use COLLATE operator
:
The COLLATE operator determines the collation for an expression. This operator enables you to override the collation that the database would have derived for the expression using standard collation derivation rules.
The COLLATE operator takes one argument, collation_name, for which you can specify a named collation or pseudo-collation. If the collation name contains a space, then you must enclose the name in double quotation marks.
Demo:
CREATE TABLE tab1(i INT PRIMARY KEY, name VARCHAR2(100));
INSERT INTO tab1(i, name) VALUES (1, 'John');
INSERT INTO tab1(i, name) VALUES (2, 'Joe');
INSERT INTO tab1(i, name) VALUES (3, 'Billy');
--========================================================================--
SELECT /*csv*/ *
FROM tab1
WHERE name = 'jOHN' ;
-- no rows selected
SELECT /*csv*/ *
FROM tab1
WHERE name COLLATE BINARY_CI = 'jOHN' ;
/*
"I","NAME"
1,"John"
*/
SELECT /*csv*/ *
FROM tab1
WHERE name LIKE 'j%';
-- no rows selected
SELECT /*csv*/ *
FROM tab1
WHERE name COLLATE BINARY_CI LIKE 'j%';
/*
"I","NAME"
1,"John"
2,"Joe"
*/
edit: As lots of people seem to want to do this, I have written up a short guide with a more general use case here https://www.atlascode.com/bootstrap-fixed-width-sidebars/. Hope it helps.
The bootstrap3 grid system supports row nesting which allows you to adjust the root row to allow fixed width side menus.
You need to put in a padding-left on the root row, then have a child row which contains your normal grid layout elements.
Here is how I usually do this http://jsfiddle.net/u9gjjebj/
html
<div class="container">
<div class="row">
<div class="col-fixed-240">Fixed 240px</div>
<div class="col-fixed-160">Fixed 160px</div>
<div class="col-md-12 col-offset-400">
<div class="row">
Standard grid system content here
</div>
</div>
</div>
</div>
css
.col-fixed-240{
width:240px;
background:red;
position:fixed;
height:100%;
z-index:1;
}
.col-fixed-160{
margin-left:240px;
width:160px;
background:blue;
position:fixed;
height:100%;
z-index:1;
}
.col-offset-400{
padding-left:415px;
z-index:0;
}
When running Nginx in a Docker container, be aware that a volume mounted over the log dir defeats the purpose of creating a softlink between the log files and stdout/stderr in your Dockerfile, as described in @Boeboe 's answer.
In that case you can either create the softlink in your entrypoint (executed after volumes are mounted) or not use a volume at all (e.g. when logs are already collected by a central logging system).
I'm running Windows 7 with git bash console. The above commands wouldn't work for me.
So I did it via Windows Explorer. I checked show hidden files, went to my projects directory and manually deleted the .git folder. Then back in the command line I checked by running git status.
Which returned...
fatal: Not a git repository (or any of the parent directories): .git
Which is exactly the result I wanted. It returned that the directory is not a git repository (anymore!).
.offset()
will return the offset position of an element as a simple object, eg:
var position = $(element).offset(); // position = { left: 42, top: 567 }
You can use this return value to position other elements at the same spot:
$(anotherElement).css(position)
$('.ct option').each(function() {
if ( $(this).val() == 'X' ) {
$(this).remove();
}
});
Or just
$('.ct option[value="X"]').remove();
Main point is that find
takes a selector string, by feeding it x
you are looking for elements named x
.

Update:
I use Compare plugin 2 for notepad++ 7.5 and newer versions. Notepad++ 7.5 and newer versions does not have plugin manager. You have to download and install plugins manually. And YES it matters if you use 64bit or 32bit (86x).
So Keep in mind, if you use 64 bit version of Notepad++, you should also use 64 bit version of plugin, and the same valid for 32bit.
I wrote a guideline how to install it:
Note:
It is also possible to drag and drop the plugin.dll
file directly in plugin folder.
64bit:%programfiles%\Notepad++\plugins
32bit:%programfiles(x86)%\Notepad++\plugins
Update Thanks to @TylerH with this update: Notepad++ Now has "Plugin Admin" as a replacement for the old Plugin Manager. But this method (answer) is still valid for adding plugins manually for almost any Notepad++ plugins.
Disclaimer: the link of this guideline refer to my personal web site.
You can get the path via fp.name
. Example:
>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'
You might need os.path.basename
if you want only the file name:
>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

It's getElementsByName()
and getElementsByTagName()
- note the "s" in "Elements", indicating that both functions return a list of elements, i.e., a NodeList, which you will access like an array. Note that the second function ends with "TagName" not "Tag".
Even if the function only returns one element it will still be in a NodeList of length one. So:
var els = document.getElementsByName('frmMain');
// els.length will be the number of elements returned
// els[0] will be the first element returned
// els[1] the second, etc.
Assuming your form is the first (or only) form on the page you can do this:
document.getElementsByName('frmMain')[0].elements
document.getElementsByTagName('table')[0].elements
Thank you first
Use overflow:auto
it works for me.
horizontal scroll bar disappears.
You'll either need to modify the service, or wrap it inside a helper process: apart from session/drive access issues, persistent drive mappings are only restored on an interactive logon, which services typically don't perform.
The helper process approach can be pretty simple: just create a new service that maps the drive and starts the 'real' service. The only things that are not entirely trivial about this are:
The helper service will need to pass on all appropriate SCM commands (start/stop, etc.) to the real service. If the real service accepts custom SCM commands, remember to pass those on as well (I don't expect a service that considers UNC paths exotic to use such commands, though...)
Things may get a bit tricky credential-wise. If the real service runs under a normal user account, you can run the helper service under that account as well, and all should be OK as long as the account has appropriate access to the network share. If the real service will only work when run as LOCALSYSTEM or somesuch, things get more interesting, as it either won't be able to 'see' the network drive at all, or require some credential juggling to get things to work.
To access the mysql
command in Windows without manually changing directories, do this:
Append the path to your MySQL installation to the end of the exisiting 'Variable value'. Example:
%systemDrive%\xampp\mysql\bin\
or, if you prefer
c:\xampp\mysql\bin\
Finally, open a new command prompt to make this change take effect.
Note that MySQL's documentation on Setting Environment Variables has little to say about handling this in Windows.
I follow the PEP8, it is a great piece of coding style.

If you're not tagetting IE6, then float the second <div>
and give it a margin equal to (or maybe a little bigger than) the first <div>
's fixed width.
HTML:
<div id="main-wrapper">
<div id="fixed-width"> lorem ipsum </div>
<div id="rest-of-space"> dolor sit amet </div>
</div>
CSS:
#main-wrapper {
100%;
background:red;
}
#fixed-width {
width:100px;
float:left
}
#rest-of-space {
margin-left:101px;
/* May have to increase depending on borders and margin of the fixd width div*/
background:blue;
}
The margin accounts for the possibility that the 'rest-of-space' <div>
may contain more content than the 'fixed-width' <div>
.
Don't give the fixed width one a background; if you need to visibly see these as different 'columns' then use the Faux Columns trick.
In my case (Rails 5), I ended up adding these 2 lines in my app/config/environments/development.rb
config.time_zone = "Melbourne"
config.active_record.default_timezone = :local
That's it! And to make sure that Melbourne was read correctly, I ran the command in my terminal:
bundle exec rake time:zones:all
and Melbourne was listing in the timezone I'm in!
I usually attach a class to the element then check if the class exist like this:
let element = document.getElementsById("someElement");
if(!element.classList.contains('attached-listener'))
element.addEventListener("click", this.itemClicked);
element.classList.add('attached-listener');
It seems to be true so far. The only SDK available from Apple only targets the macOS environment. I've been upset about that, but I'm looking into buying a mac now, just to do iPhone development. I really dislike what they are doing, and I hope a good SDK come out for other environments, such as Linux and Windows.
Obstacles regarding the SDK:
The iPhone SDK and free software: not a match
Apple's recently released a software development kit (SDK) for the iPhone, but if you were hoping to port or develop original open source software with it, the news isn't good. Code signing and nondisclosure conditions make free software a no-go.
The SDK itself is a free download, with which you can write programs and run them on a software simulator. But in order to actually release software you've written, you must enroll in the iPhone Developer Program -- a step separate from downloading the SDK, and one that requires Apple's approval.
I think it's rather elitist for them to think only macOS users are good enough to write programs for their phone, and the fact you need to buy a $100 license if you want to publish your stuff, really makes it more difficult for the hobbyist programmer. Though, if that's what you need to do, I'm planning on jumping through their hoops; I'd really like to get some stuff developed on my iPhone.
Use a case
statement:
select id,
case report.type
when 'P' then amount
when 'N' then -amount
end as amount
from
`report`
For the purpose of my code I found out this decision which corresponds with some of the answers above:
ES6 variant:
const checkType = o => Object.prototype
.toString
.call(o)
.replace(/\[|object\s|\]/g, '')
.toLowerCase();
ES5 variant:
function checkType(o){
return Object.prototype
.toString
.call(o)
.replace(/\[|object\s|\]/g, '')
.toLowerCase();
}
You can use it very simply:
checkType([]) === 'array'; // true
checkType({}) === 'object'; // true
checkType(1) === 'number'; // true
checkType('') === 'string'; // true
checkType({}.p) === 'undefined'; // true
checkType(null) === 'null'; // true
and so on..
Be aware of the "date=iso
" format: it isn't exactly ISO 8601.
See commit "466fb67" from Beat Bolli (bbolli
), for Git 2.2.0 (November 2014)
Git's "ISO" date format does not really conform to the ISO 8601 standard due to small differences, and it cannot be parsed by ISO 8601-only parsers, e.g. those of XML toolchains.
The output from "
--date=iso
" deviates from ISO 8601 in these ways:
- a space instead of the
T
date/time delimiter- a space between time and time zone
- no colon between hours and minutes of the time zone
Add a strict ISO 8601 date format for displaying committer and author dates.
Use the '%aI
' and '%cI
' format specifiers and add '--date=iso-strict
' or '--date=iso8601-strict
' date format names.
See this thread for discussion.
Extract characters from a string:
var str = "Hello world!";
var res = str.substring(1,4);
The result of res
will be:
ell
http://www.w3schools.com/jsref/jsref_substring.asp
$('.dep_buttons').mouseover(function(){
$(this).text().substring(0,25);
if($(this).text().length > 30) {
$(this).stop().animate({height:"150px"},150);
}
$(".dep_buttons").mouseout(function(){
$(this).stop().animate({height:"40px"},150);
});
});
In order for this to work that Javascript must be placed within a Razor view so that the line
@Url.Action("Action","Controller")
is parsed by Razor and the real value replaced.
If you don't want to move your Javascript into your View you could look at creating a settings object in the view and then referencing that from your Javascript file.
e.g.
var MyAppUrlSettings = {
MyUsefulUrl : '@Url.Action("Action","Controller")'
}
and in your .js file
$.ajax({
type: "POST",
url: MyAppUrlSettings.MyUsefulUrl,
data: "{queryString:'" + searchVal + "'}",
contentType: "application/json; charset=utf-8",
dataType: "html",
success: function (data) {
alert("here" + data.d.toString());
});
or alternatively look at levering the framework's built in Ajax methods within the HtmlHelpers which allow you to achieve the same without "polluting" your Views with JS code.
Lets say we have existing list, and gonna use java 8 for this activity `
import java.util.*;
import java.util.stream.Collectors;
public class AddingArray {
public void addArrayInList(){
List<Integer> list = Arrays.asList(3, 7, 9);
// And we have an array of Integer type
int nums[] = {4, 6, 7};
//Now lets add them all in list
// converting array to a list through stream and adding that list to previous list
list.addAll(Arrays.stream(nums).map(num ->
num).boxed().collect(Collectors.toList()));
}
}
`
There are three ways to do what you want
This includes something like php, asp, jsp.... But you said no to that
Your server is serving up the pages so why not take advantage of the built in server side includes? Each server has its own way to do this, take advantage of it.
This solutions has you calling back to the server after page has already been loaded on the client.
The Inversion of Control (IoC) and Dependency Injection (DI) patterns are all about removing dependencies from your code.
For example, say your application has a text editor component and you want to provide spell checking. Your standard code would look something like this:
public class TextEditor {
private SpellChecker checker;
public TextEditor() {
this.checker = new SpellChecker();
}
}
What we've done here creates a dependency between the TextEditor
and the SpellChecker
.
In an IoC scenario we would instead do something like this:
public class TextEditor {
private IocSpellChecker checker;
public TextEditor(IocSpellChecker checker) {
this.checker = checker;
}
}
In the first code example we are instantiating SpellChecker
(this.checker = new SpellChecker();
), which means the TextEditor
class directly depends on the SpellChecker
class.
In the second code example we are creating an abstraction by having the SpellChecker
dependency class in TextEditor
's constructor signature (not initializing dependency in class). This allows us to call the dependency then pass it to the TextEditor class like so:
SpellChecker sc = new SpellChecker(); // dependency
TextEditor textEditor = new TextEditor(sc);
Now the client creating the TextEditor
class has control over which SpellChecker
implementation to use because we're injecting the dependency into the TextEditor
signature.
you can put everything in a block and easily write any code that you wish in that block just exactly the below code :
@{
bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
if (isUserConnected)
{ // meaning that the viewing user has not been saved
<div>
<div> click to join us </div>
<a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
</div>
}
}
it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes
I use this script for autocomplete...
$('#custmoers_name').autocomplete({
source: function (request, response) {
// $.getJSON("<?php echo base_url('index.php/Json_cr_operation/autosearch_custmoers');?>", function (data) {
$.getJSON("Json_cr_operation/autosearch_custmoers?term=" + request.term, function (data) {
console.log(data);
response($.map(data, function (value, key) {
console.log(value);
return {
label: value.label,
value: value.value
};
}));
});
},
minLength: 1,
delay: 100
});
My json return :- [{"label":"Mahesh Arun Wani","value":"1"}]
after search m
but it display in dropdown [object object]
...
For a simple plain JavaScript implementation:
window.onbeforeunload = function () {_x000D_
window.scrollTo(0, 0);_x000D_
}
_x000D_
You can write a script and then use nohup ./yourscript &
to execute
For example:
vi yourscript
put
#!/bin/bash
script here
you may also need to change permission to run script on server
chmod u+rwx yourscript
finally
nohup ./yourscript &

It was was very useful for me on MacOS.
Open Termnal (bash console) and do below things:
$ pwd /Users/You/YourEclipseInstalationDirectory
$ cd Eclipse.app/Contents/MacOS/
$ echo "-Duser.name=Your Name" >> eclipse.ini
$ cat eclipse.ini
Close Terminal and start/open Eclipse again.
This is a late answer, but I believe it is still useful.
I have created the NinjaNye.SearchExtension nuget package that can help solve this very problem.:
string[] terms = new[]{"search", "term", "collection"};
var result = context.Table.Search(terms, x => x.Name);
You could also search multiple string properties
var result = context.Table.Search(terms, x => x.Name, p.Description);
Or perform a RankedSearch
which returns IQueryable<IRanked<T>>
which simply includes a property which shows how many times the search terms appeared:
//Perform search and rank results by the most hits
var result = context.Table.RankedSearch(terms, x => x.Name, x.Description)
.OrderByDescending(r = r.Hits);
Hope this helps future visitors
You can use display:inline-block
to force this behavior
If you don't care about the number of occurrences, I would approach it like this. Using hash sets will give you better performance than simple iteration.
var set1 = new HashSet<MyType>(list1);
var set2 = new HashSet<MyType>(list2);
return set1.SetEquals(set2);
This will require that you have overridden .GetHashCode()
and implemented IEquatable<MyType>
on MyType
.
I've been looking through stack overflow to find a good answer and when i couldn't find one i went looking through the docs.
no one seems to have stumbled on this simple answer yet:
ViewCompat.setTranslationZ(view, translationZ);
default translation z is 0.0
