Just add a .
to it:
svn checkout file:///home/landonwinters/svn/waterproject/trunk .
That means: check out to current directory.
You've already discovered the simplest way to specify a shallow clone in Git-SVN, by specifying the SVN revision number that you want to start your clone at ( -r$REV:HEAD
).
For example: git svn clone -s -r1450:HEAD some/svn/repo
Git's data structure is based on pointers in a directed acyclic graph (DAG), which makes it trivial to walk back n
commits. But in SVN ( and therefore in Git-SVN) you will have to find the revision number yourself.
Additional musings. You said insmod crashes. Insmod loads modules. The modules are built in another compile operation from building the kernel. Kernel and modules have to be built from the same headers and so forth. Are all the modules built during the kernel build, or are they "existing"?
The other idea, and something I know little about, is svn externals, which (if used) can affect what is checked out to your project. Look and see if this is any different when exporting.
Simply add Templates URL:
<a href="{% url 'service_data' d.id %}">

The problem is in your playerMovement
method. You are creating the string name of your room variables (ID1
, ID2
, ID3
):
letsago = "ID" + str(self.dirDesc.values())
However, what you create is just a str
. It is not the variable. Plus, I do not think it is doing what you think its doing:
>>>str({'a':1}.values())
'dict_values([1])'
If you REALLY needed to find the variable this way, you could use the eval
function:
>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'
or the globals
function:
class Foo(object):
def __init__(self):
super(Foo, self).__init__()
def test(self, name):
print(globals()[name])
foo = Foo()
bar = 'Hello World!'
foo.text('bar')
However, instead I would strongly recommend you rethink you class(es). Your userInterface
class is essentially a Room
. It shouldn't handle player movement. This should be within another class, maybe GameManager
or something like that.
Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).
Keep it simple!
var classes = $(this).parent('div').attr('class');
BYTE is nothing but typedef unsigned char BYTE;
You can easily use any of below constructors
string ( const char * s, size_t n );
string ( const char * s );
You can use gcd to do this without having to create another method
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
NSLog(@"Do some work");
});
You should still ask yourself "do I really need to add a delay" as it can often complicate code and cause race conditions
Vertex *f=(findvertex(from));
if(!f) {
cerr << "vertex not found" << endl;
exit(1) // or return;
}
Because findVertex
can return NULL
if it can't find the vertex.
Otherwise this f->adj;
is trying to do
NULL->adj;
Which causes access violation.
Those pesky black dots you are referencing to are called bullets.
They are pretty simple to remove, just add this line to your css:

See below link : http://www.asciitable.com/
public static char randomSeriesForThreeCharacter() {
Random r = new Random();
char random_3_Char = (char) (48 + r.nextInt(47));
return random_3_Char;
}
Now you can generate a character at one time of calling.
I wanted to keep my html very minimal, so defined a small filter that creates the array [0,1,2,...] as others have done:
angular.module('awesomeApp')
.filter('range', function(){
return function(n) {
var res = [];
for (var i = 0; i < n; i++) {
res.push(i);
}
return res;
};
});
After that, on the view is possible to use like this:
<ul>
<li ng-repeat="i in 5 | range">
{{i+1}} <!-- the array will range from 0 to 4 -->
</li>
</ul>
You might be interested in a proposal for some new operators that are similar to the conditional operator. The null-safe operators will enable code like this:
String s = mayBeNull?.toString() ?: "null";
It would be especially convenient where auto-unboxing takes place.
Integer ival = ...; // may be null
int i = ival ?: -1; // no NPE from unboxing
It has been selected for further consideration under JDK 7's "Project Coin."
As @ingyhere said:
Shallow Clone
First, turn off compression:
git config --global core.compression 0
Next, let's do a partial clone to truncate the amount of info coming down:
git clone --depth 1 <repo_URI>
When that works, go into the new directory and retrieve the rest of the clone:
git fetch --unshallow
or, alternately,
git fetch --depth=2147483647
Now, do a pull:
git pull --all
Then to solve the problem of your local branch only tracking master
open your git config file (.git/config
) in the editor of your choice
where it says:
[remote "origin"]
url=<git repo url>
fetch = +refs/heads/master:refs/remotes/origin/master
change the line
fetch = +refs/heads/master:refs/remotes/origin/master
to
fetch = +refs/heads/*:refs/remotes/origin/*
Do a git fetch and git will pull all your remote branches now
Sometimes value stored in Database could contain spaces so running this could be fail
String.Equals(row.Name, "test", StringComparison.OrdinalIgnoreCase)
Solution to this problems is to remove space then convert its case then select like this
return db.UsersTBs.Where(x => x.title.ToString().ToLower().Replace(" ",string.Empty).Equals(customname.ToLower())).FirstOrDefault();
Note in this case
customname is value to match with Database value
UsersTBs is class
title is the Database column
If you need the for
statement to contain only the if
, you need to remove its else
, like this:
for(int i=0; i<something_in_the_array.length;i++)
if(whatever_value==(something_in_the_array[i]))
{
value=2;
break;
}
/*this "else" must go*/
if(whatever_value==2)
{
value=3;
break;
}
else if(whatever_value==3)
{
value=4;
break;
}
According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.
However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

GCC supports #pragma once
since 3.4, see http://en.wikipedia.org/wiki/Pragma_once for further compiler support.
The big upside I see on using #pragma once
as opposed to include guards is to avoid copy/paste errors.
Let's face it: most of us hardly start a new header file from scratch, but rather just copy an existing one and modify it to our needs. It is much easier to create a working template using #pragma once
instead of include guards. The less I have to modify the template, the less I am likely to run into errors. Having the same include guard in different files leads to strange compiler errors and it takes some time to figure out what went wrong.
TL;DR: #pragma once
is easier to use.

undefined index means that somewhere in the $_POST array, there isn't an index (key) for the key username.
You should be setting your posted values into variables for a more clean solution, and it's a good habit to get into.
If I was having a similar error, I'd do something like this:
$username = $_POST['username']; // you should really do some more logic to see if it's set first
echo $username;
If username didn't turn up, that'd mean I was screwing up somewhere. You can also,
var_dump($_POST);
To see what you're posting. var_dump is really useful as far as debugging. Check it out: var_dump

Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.
If you want to check if a property exists: hasOwnProperty is the way to go
And since most objects are properties of some other object (eventually leading to the window
object) this can work well for checking if values have been declared.
It seems that the shortest way is to combine LINQ and string.Concat
:
var input = @"My name @is ,Wan.;'; Wan";
var chrs = new[] {'@', ',', '.', ';', '\''};
var result = string.Concat(input.Where(c => !chrs.Contains(c)));
// => result = "My name is Wan Wan"
See the C# demo. Note that string.Concat
is a shortcut to string.Join("", ...)
.
Note that using a regex to remove individual known chars is still possible to build dynamically, although it is believed that regex is slower. However, here is a way to build such a dynamic regex (where all you need is a character class):
var pattern = $"[{Regex.Escape(new string(chrs))}]+";
var result = Regex.Replace(input, pattern, string.Empty);
See another C# demo. The regex will look like [@,\.;']+
(matching one or more (+
) consecutive occurrences of @
, ,
, .
, ;
or '
chars) where the dot does not have to be escaped, but Regex.Escape
will be necessary to escape other chars that must be escaped, like \
, ^
, ]
or -
whose position inside the character class you cannot predict.
Do everything suggested by ziesemer.

It may be a little late for the original question but for future queries this might help. Best way to achieve this is Get the result of the inner query to an array like this
$this->db->select('id');
$result = $this->db->get('your_table');
return $result->result_array();
And then use than array in the following active record clause
$this->db->where_not_in('id_of_another_table', 'previously_returned_array');
Hope this helps
Thank you for this thread. I've been having a hard time implementing a Timer in my code for 5 minutes to run an activity, because my phone I have set to screen off/sleep around 2 minutes. With the above information it appears I have been able to get the work around.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* Time Lockout after 5 mins */
getWindow().addFlags(LayoutParams.FLAG_KEEP_SCREEN_ON);
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
Intent i = new Intent(AccountsList.this, AppEntryActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();
return;
}
}, 300000);
/* Time Lockout END */
}
You may also have a look on Runtyper - a tool that performs type checking of operands in ===
(and other operations).
For your example, if you have strict comparison x === y
and x = 123, y = "123"
, it will automatically check typeof x, typeof y
and show warning in console:
Strict compare of different types: 123 (number) === "123" (string)
If you use constants then you have no choice:
const numbers = [1, 2, 3]
You can not reasign:
numbers = []
You can only truncate:
numbers.length = 0
$variable = substr($initial, 0, strpos($initial, "By"));
if (!empty($variable)) { echo $variable; } else { echo $initial; }
It's a hex number and is 16 decimal.
The (un)safe way to do this - if you are ok with not using option explicit - is...
Not TypeName(myObj) = "Empty"
This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...
Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ true, the object exists - TypeName is Object
'Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ false, the object has not been declared
This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.
String array[]=new String[]; and String array[]=new String[]{};
No difference,these are just different ways of declaring array
String array=new String[10]{}; got error why ?
This is because you can not declare the size of the array in this format.
right way is
String array[]=new String[]{"a","b"};
In my case the bucketname was wrong, it included the first part of the key (bucketxxx/keyxxx) - there was nothing wrong with the signature.
Jquery.ajax does not encode POST data for you automatically the way that it does for GET data. Jquery expects your data to be pre-formated to append to the request body to be sent directly across the wire.
A solution is to use the jQuery.param function to build a query string that most scripts that process POST requests expect.
$.ajax({
url: 'superman',
type: 'POST',
data: jQuery.param({ field1: "hello", field2 : "hello2"}) ,
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function (response) {
alert(response.status);
},
error: function () {
alert("error");
}
});
In this case the param
method formats the data to:
field1=hello&field2=hello2
The Jquery.ajax documentation says that there is a flag called processData
that controls whether this encoding is done automatically or not. The documentation says that it defaults to true
, but that is not the behavior I observe when POST
is used.
The loop only breaks if you return literally false
. Ex:
// this is how jquery calls your function
// notice hard comparison (===) against false
if ( callback.call( obj[ i ], i, obj[ i ] ) === false ) {
break;
}
This means you can return anything else, including undefined
, which is what you return if you return nothing, so you can simply use an empty return statement:
$.each(collection, function (index, item) {
if (!someTestCondition)
return; // go to next iteration
// otherwise do something
});
It's possible this might vary by version; this is applicable for jquery 1.12.4. But really, when you exit out the bottom of the function, you are also returning nothing, and that's why the loop continues, so I would expect that there is no possibility whatsoever that returning nothing could not continue the loop. Unless they want to force everyone to start returning something to keep the loop going, returning nothing has to be a way to keep it going.
Well, this is another solution that some of you guys might be looking for (as I was..)
My problem was similar, the modal box was closing while the iframe I had inside was loading, so I had to disable the modal dismiss until the Iframe finishes loading, then re-enable.
The solutions presented here were not working 100%.
My solution was this:
showLocationModal = function(loc){
var is_loading = true;
if(is_loading === true) {
is_loading = false;
var $modal = $('#locationModal');
$modal.modal({show:true});
// prevent Modal to close before the iframe is loaded
$modal.on("hide", function (e) {
if(is_loading !== true) {
e.preventDefault();
return false
}
});
// populate Modal
$modal.find('.modal-body iframe').hide().attr('src', location.link).load(function(){
is_loading = true;
});
}};
So I temporarily prevent the Modal from closing with:
$modal.on("hide", function (e) {
if(is_loading !== true) {
e.preventDefault();
return false
}
});
But ith the var is_loading that will re enable closing after the Iframe has loaded.
With the upcoming release of iOS 7 you will notice that the "standard" icon radius has been increased. So try to do what Apple and I suggested with this answer.
It appears that for a 120px icon the formula that best represents its shape on iOS 7 is the following superellipse:
|x/120|^5 + |y/120|^5 = 1
Obviously you can change the 120
number with the desired icon size to get the corresponding function.
Original
You should provide an image that has 90° corners (it’s important to avoid cropping the corners of your icon—iOS does that for you when it applies the corner-rounding mask) (Apple Documentation)
The best approach is not rounding the corners of your icons at all. If you set your icon as a square icon, iOS will automatically overlay the icon with a predefined mask that will set the appropriate rounded corners.
If you manually set rounded corners for your icons, they will probably look broken in this or that device, because the rounding mask happens to slightly change from an iOS version to another. Sometimes your icons will be slightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.
This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed this approach a couple of times, and if you want I can post you a link to an app that uses native square icons.
Edit
To better understand this answer, please refer to the official Apple documentation about iOS icons. In this page it is clearly stated that a square icon will automatically get these things when displayed on an iOS device:
So, you can achieve whatever effect you want just drawing a plain square icon and filling content in it. The final corner radius will be something similar to what the other answers here are saying, but this will never be guaranteed, since those numbers are not part of the official Apple documentation on iOS. They ask you to draw square icons, so ... why not?
One big gotcha is that PHP is disabled in user home directories by default, so if you are testing from ~/public_html it doesn't work. Check /etc/apache2/mods-enabled/php5.conf
# Running PHP scripts in user directories is disabled by default
#
# To re-enable PHP in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
#<IfModule mod_userdir.c>
# <Directory /home/*/public_html>
# php_admin_flag engine Off
# </Directory>
#</IfModule>
Other than that installing in Ubuntu is real easy, as all the stuff you used to have to put in httpd.conf is done automatically.

You can not call remote set-url origin
just after git init
, Because the git remote set-url
command will not create origin, but it changes an existing remote repository URL.
so the command git remote set-url
will only work if you've either cloned the repository or manually added a remote called origin.
you can check remote with command git remote -v
it will show remote url after name, or if this command gives error like fatal: Not a git repository (or any of the parent directories): .git
then the repository not exists, so you have to add origin with command git remote add
1. git remote add
This command is used to add a new remote, you can use this command on the terminal, in the directory of your repository.
The git remote add command takes two arguments:
For example:
git remote add origin https://github.com/user/repo.git
2.git remote set-url
The git remote set-url command changes an existing remote repository URL.
The git remote set-url command takes two arguments:
origin
or upstream
are two common choices.For example you can change your remote's URL from SSH to HTTPS with the git remote set-url
command.
git remote set-url origin https://github.com/USERNAME/REPOSITORY.git
you can verify that the remote URL has changed, with command git remote -v
.
note: "origin" is a convention not part of the command. "origin" is the local name of the remote repository. you can use any name instead of "origin".
For example:
git remote add myorigin [email protected]:user/repo.git
git remote set-url myorigin https://github.com/user/repo.git
References from github: remote add, remote set-url
I had the same problem, here is my solution:
<form method="post" class="form-inline form-horizontal" role="form">
<label class="control-label col-sm-5" for="jbe"><i class="icon-envelope"></i> Email me things like this: </label>
<div class="input-group col-sm-7">
<input class="form-control" type="email" name="email" placeholder="[email protected]"/>
<span class="input-group-btn">
<button class="btn btn-primary" type="submit">Submit</button>
</span>
</div>
</form>
here is the Demo
I would think that one reason could be that the color is applied to things other than font. For example:
div {
border: 1px solid;
color: red;
}
Yields both a red font color and a red border.
Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.
Or a comparison on the class name e.g.
except ClientError as e:
if 'EntityAlreadyExistsException' == e.__class__.__name__:
# handle specific error
Because they are dynamically created you can never import the class and catch it using real Python.
You could also do
function insertAfter(node1, node2) {
node1.outerHTML += node2.outerHTML;
}
or
function insertAfter2(node1, node2) {
var wrap = document.createElement("div");
wrap.appendChild(node2.cloneNode(true));
var node2Html = wrap.innerHTML;
node1.insertAdjacentHTML('afterend', node2Html);
}
Without looking at it, set it to not itself. I don't know how to code it in Java, but in Objective-C I would say
booleanVariable = !booleanVariable;
This flips the variable.
Since you are learning Git, know that this has little to do with git but with the text editor configured for use. In vim, you can press i
to start entering text and save by pressing esc
and :wq
and enter
, this will commit with the message you typed. In your current state, to just come out without committing, you can do :q
instead of the :wq
as mentioned above.
Alternatively, you can just do git commit -m '<message>'
instead of having git open the editor to type the message.
Note that you can also change the editor and use something you are comfortable with ( like notepad) - How can I set up an editor to work with Git on Windows?
Although you should have no problem running a 2005 instance of the database engine beside a 2008 instance, The tools are installed into a shared directory, so you can't have two versions of the tools installed. Fortunately, the 2008 tools are backwards-compatible. As we speak, I'm using SSMS 2008 and Profiler 2008 to manage my 2005 Express instances. Works great.
Before installing the 2008 tools, you need to remove any and all "shared" components from 2005. Try going to your Add/Remove programs control panel, find Microsoft SQL Server 2005, and click "Change." Then choose "Workstation Components" and remove everything there (this will not remove your database engine).
I believe the 2008 installer also has an option to upgrade shared components only. You might try that. Good luck!
Here is another one:

This one is also based on the latest Chrome engine but it's much easier to use than CEF. It's a single .NET dll that you can simply reference and use.
Yes, you can access it through GET
and POST
(trying this simple task would have made you aware of that).
Yes, there are other ways, one of the other "preferred" ways is using sessions. When you would want to use hidden over session is kind of touchy, but any GET / POST data is easily manipulated by the end user. A session is a bit more secure given it is saved to a file on the server and it is much harder for the end user to manipulate without access through the program.
Here is a method for converting from a GregorianCalendar to XMLGregorianCalendar; I'll leave the part of converting from a java.util.Date to GregorianCalendar as an exercise for you:
import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;
public class DateTest {
public static void main(final String[] args) throws Exception {
GregorianCalendar gcal = new GregorianCalendar();
XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
.newXMLGregorianCalendar(gcal);
System.out.println(xgcal);
}
}
EDIT: Slooow :-)
Using kotlin and its Coroutine its quite easy, first declare a job in your class (better in your viewModel) like this:
private var repeatableJob: Job? = null
then when you want to create and start it do this:
repeatableJob = viewModelScope.launch {
while (isActive) {
delay(5_000)
loadAlbums(iImageAPI, titleHeader, true)
}
}
repeatableJob?.start()
and if you want to finish it:
repeatableJob?.cancel()
PS: viewModelScope
is only available in view models, you can use other Coroutine scopes such as withContext(Dispatchers.IO)
More information: Here
string k = "This is my\r\nugly string. I want\r\nto change this. Please \r\n help!";
k = System.Text.RegularExpressions.Regex.Replace(k, @"\r\n+", " ");
It's a function which is a member of a class:
class C:
def my_method(self):
print("I am a C")
c = C()
c.my_method() # Prints("I am a C")
Simple as that!
(There are also some alternative kinds of method, allowing you to control the relationship between the class and the function. But I'm guessing from your question that you're not asking about that, but rather just the basics.)
SQl Management Studio data import looks at the first few rows to determine source data specs..

Here is a really simple way to set the timeout:
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());
private ClientHttpRequestFactory getClientHttpRequestFactory() {
int timeout = 5000;
HttpComponentsClientHttpRequestFactory clientHttpRequestFactory =
new HttpComponentsClientHttpRequestFactory();
clientHttpRequestFactory.setConnectTimeout(timeout);
return clientHttpRequestFactory;
}
if a method is not static, that "tells" the compiler that the method requires access to instance-level data in the class, (like a non-static field). This data would not be available unless an instance of the class has been created. So the compiler throws an error if you try to call the method from a static method.. If in fact the method does NOT reference any non-static member of the class, make the method static.
In Resharper, for example, just creating a non-static method that does NOT reference any static member of the class generates a warning message "This method can be made static"

To answer the specific question, in C# you are likely to be using the C# keyboard mapping scheme, which will use these hotkeys by default:
Ctrl+E, Ctrl+D to format the entire document.
Ctrl+E, Ctrl+F to format the selection.
You can change these in menu Tools ? Options ? Environment ? Keyboard (either by selecting a different "keyboard mapping scheme", or binding individual keys to the commands "Edit.FormatDocument" and "Edit.FormatSelection").
If you have not chosen to use the C# keyboard mapping scheme, then you may find the key shortcuts are different. For example, if you are not using the C# bindings, the keys are likely to be:
Ctrl + K + D (Entire document)
Ctrl + K + F (Selection only)
To find out which key bindings apply in your copy of Visual Studio, look in menu Edit ? Advanced menu - the keys are displayed to the right of the menu items, so it's easy to discover what they are on your system.
(Please do not edit this answer to change the key bindings above to what your system has!)
Default is:
Username: root
Password: [null]
The Password is set to 'password' in some versions.
I just had the same error with Visual Studio 2013 and EF6. I had to use a NewGet packed Entity Framework and done the job perfectly
I could get result by using following:
$resu = mysqli_fetch_assoc(mysqli_query($conn, "SELECT * FROM employees1 WHERE pkint =58"));
echo ( "<br />". $resu['pkint']). "<br />" . $resu['f1'] . "<br />" . $resu['f2']. "<br />" . $resu['f3']. "<br />" . $resu['f4' ];
employees 1 is table name. pkint is primary key id. f1,f2,f3,f4 are field names. $resu is the variable shortcut for result. Following is the output:
<br />58
<br />Caroline
<br />Smith
<br />Zandu Balm
Right-click on the widget and choose "center" -> "horizontally". Then choose "center"->"vertically".
I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload
instruction was immediately evaluated, and then the $
usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).
So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.
var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
console.log("script loaded :)");
onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);
For my needs, it works fine now. Hope this can help others :)
If you don't want to use SMO (which is better than the solution below, but i want to give an alternative...) you can split your query with this function.
It is:
String proof (example print 'no go ')
private List<string> SplitScriptGo(string script)
{
var result = new List<string>();
int pos1 = 0;
int pos2 = 0;
bool whiteSpace = true;
bool emptyLine = true;
bool inStr = false;
bool inComment1 = false;
bool inComment2 = false;
while (true)
{
while (pos2 < script.Length && Char.IsWhiteSpace(script[pos2]))
{
if (script[pos2] == '\r' || script[pos2] == '\n')
{
emptyLine = true;
inComment1 = false;
}
pos2++;
}
if (pos2 == script.Length)
break;
bool min2 = (pos2 + 1) < script.Length;
bool min3 = (pos2 + 2) < script.Length;
if (!inStr && !inComment2 && min2 && script.Substring(pos2, 2) == "--")
inComment1 = true;
if (!inStr && !inComment1 && min2 && script.Substring(pos2, 2) == "/*")
inComment2 = true;
if (!inComment1 && !inComment2 && script[pos2] == '\'')
inStr = !inStr;
if (!inStr && !inComment1 && !inComment2 && emptyLine
&& (min2 && script.Substring(pos2, 2).ToLower() == "go")
&& (!min3 || char.IsWhiteSpace(script[pos2 + 2]) || script.Substring(pos2 + 2, 2) == "--" || script.Substring(pos2 + 2, 2) == "/*"))
{
if (!whiteSpace)
result.Add(script.Substring(pos1, pos2 - pos1));
whiteSpace = true;
emptyLine = false;
pos2 += 2;
pos1 = pos2;
}
else
{
pos2++;
whiteSpace = false;
if (!inComment2)
emptyLine = false;
}
if (!inStr && inComment2 && pos2 > 1 && script.Substring(pos2 - 2, 2) == "*/")
inComment2 = false;
}
if (!whiteSpace)
result.Add(script.Substring(pos1));
return result;
}
I'm doing UnPivot
first and storing the results in CTE
and using the CTE
in Pivot
operation.
with cte as
(
select 'Paul' as Name, color, Paul as Value
from yourTable
union all
select 'John' as Name, color, John as Value
from yourTable
union all
select 'Tim' as Name, color, Tim as Value
from yourTable
union all
select 'Eric' as Name, color, Eric as Value
from yourTable
)
select Name, [Red], [Green], [Blue]
from
(
select *

pivot
(

Simplest solution would be -
$('.selectpicker').trigger('change');
It's not enough to have just compile project("xy")
dependency.
You need to configure root project to include all modules (or to call them subprojects but that might not be correct word here).
Create a settings.gradle file in the root of your project and add this:
include ':progressfragment'
to that file. Then sync Gradle and it should work.
Also one interesting side note: If you add ':unexistingProject' in settings.gradle (project that you haven't created yet), Gradle will create folder for this project after sync (at least in Android studio this is how it behaves). So, to avoid errors with settings.gradle when you create project from existing files, first add that line to file, sync and then put existing code in created folder. Unwanted behavior arising from this might be that if you delete the project folder and then sync folder will come back empty because Gradle sync recreated it since it is still listed in settings.gradle.
Depending on what you want the file to contain:
touch /path/to/file
for an empty filesomecommand > /path/to/file
for a file containing the output of some command.
eg: grep --help > randomtext.txt
echo "This is some text" > randomtext.txt
nano /path/to/file
or vi /path/to/file
(or any other editor emacs,gedit etc
)
It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist
Create the file using cat
$ cat > myfile.txt
Now, just type whatever you want in the file:
Hello World!
CTRL-D to save and exit
There are several possible solutions:
touch file
>file
echo -n > file
printf '' > file
The echo
version will work only if your version of echo
supports the -n
switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.
echo '' > file
printf '\n' > file
This is a valid "text file" because it ends in a newline.
"$EDITOR" file
echo 'text' > file
cat > file <<END \
text
END
printf 'text\n' > file
These are equivalent. The $EDITOR
command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat
version presumes a literal newline after the \
and after each other line. Other than that these will all work in a POSIX shell.
Of course there are many other methods of writing and creating files, too.
This can be done with setjmp/longjmp
in C. P99 has a quite comfortable toolset for this that also is consistent with the new thread model of C11.
Scenario:
Your domain: mydomain.com
Domain you wish to send to: theirdomain.com
1. Determine the mail server you're sending to. Open a CMD prompt Type
NSLOOKUP
set q=mx
theirdomain.com
Response:
Non-authoritative answer:
theirdomain.com MX preference = 50, mail exchanger = mail.theirdomain.com
Nslookup_big
EDIT Be sure to type exit to terminate NSLOOKUP.
2. Connect to their mail server
SMTP communicates over port 25. We will now try to use TELNET to connect to their mail server "mail.theirdomain.com"
Open a CMD prompt
TELNET MAIL.THEIRDOMAIN.COM 25
You should see something like this as a response:
220 mx.google.com ESMTP 6si6253627yxg.6
Be aware that different servers will come up with different greetings but you should get SOMETHING. If nothing comes up at this point there are 2 possible problems. Port 25 is being blocked at your firewall, or their server is not responding. Try a different domain, if that works then it's not you.
3. Send an Email
Now, use simple SMTP commands to send a test email. This is very important, you CANNOT use the backspace key, it will work onscreen but not be interpreted correctly. You have to type these commands perfectly.
ehlo mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
This is a test, please do not respond
.
quit
So, what does that all mean? EHLO - introduce yourself to the mail server HELO can also be used but EHLO tells the server to use the extended command set (not that we're using that).
MAIL FROM - who's sending the email. Make sure to place this is the greater than/less than brackets as many email servers will require this (Postini).
RCPT TO - who you're sending it to. Again you need to use the brackets. See Step #4 on how to test relaying mail!
DATA - tells the SMTP server that what follows is the body of your email. Make sure to hit "Enter" at the end.
. - the period alone on the line tells the SMTP server you're all done with the data portion and it's clear to send the email.
quit - exits the TELNET session.
4. Test SMTP relay Testing SMTP relay is very easy, and simply requires a small change to the above commands. See below:
ehlo mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
This is a test, please do not respond
.
quit
See the difference? On the RCPT TO line, we're sending to a domain that is not controlled by the SMTP server we're sending to. You will get an immediate error is SMTP relay is turned off. If you're able to continue and send an email, then relay is allowed by that server.

Having a table with a foreign key to itself does make sense to me.
You can then use a common table expression in SQL or the connect by prior statement in Oracle to build your tree.
Use the zzz

Result:

Some culture settings uses periods instead of colons for time, so you might want to use literal colons instead of time separators:

By combining PIPESTATUS[0]
and the result of executing the exit
command in a subshell, you can directly access the return value of your initial command:
command | tee ; ( exit ${PIPESTATUS[0]} )
Here's an example:
# the "false" shell built-in command returns 1
false | tee ; ( exit ${PIPESTATUS[0]} )
echo "return value: $?"
will give you:
return value: 1
Creating and destroying the connections in each query maybe complicated, i had some headaches with a server migration when i decided to install MariaDB instead MySQL. For some reason in the file etc/my.cnf the parameter wait_timeout had a default value of 10 sec (it causes that the persistence can't be implemented). Then, the solution was set it in 28800, that's 8 hours. Well, i hope help somebody with this "güevonada"... excuse me for my bad english.
I'm confused by your question, seems to me that the question title and body are asking different things. If you want to disable/enable a click event on a div simply do:
$("#id").on('click', function(){ //enables click event
//do your thing here
});
$("#id").off('click'); //disables click event
If you want to disable a div, use the following code:
$("#id").attr('disabled','disabled');
Hope this helps.
edit: oops, didn't see the other bind/unbind answer. Sorry. Those methods are also correct, though they've been deprecated in jQuery 1.7, and replaced by on()/off()

put your CA & root certificate in /usr/share/ca-certificate or /usr/local/share/ca-certificate. Then
dpkg-reconfigure ca-certificates
or even reinstall ca-certificate package with apt-get.
After doing this your certificate is collected into system's DB: /etc/ssl/certs/ca-certificates.crt
Then everything should be fine.
I would like to make a little bit more emphasis on some key differences between res.end()
& res.send()
with respect to response headers and why they are important.
1. res.send() will check the structure of your output and set header information accordingly.
app.get('/',(req,res)=>{
res.send('<b>hello</b>');
});
app.get('/',(req,res)=>{
res.send({msg:'hello'});
});
Where with res.end() you can only respond with text and it will not set "Content-Type"
app.get('/',(req,res)=>{
res.end('<b>hello</b>');
});
2. res.send() will set "ETag" attribute in the response header
app.get('/',(req,res)=>{
res.send('<b>hello</b>');
});
¿Why is this tag important?
The ETag HTTP response header is an identifier for a specific version of a resource. It allows caches to be more efficient, and saves bandwidth, as a web server does not need to send a full response if the content has not changed.
res.end()
will NOT set this header attribute

Returning &iterator will return the address of the iterator. If you want to return a way of referring to the element return the iterator itself.
Beware that you do not need the vector to be a global in order to return the iterator/pointer, but that operations in the vector can invalidate the iterator. Adding elements to the vector, for example, can move the vector elements to a different position if the new size() is greater than the reserved memory. Deletion of an element before the given item from the vector will make the iterator refer to a different element.
In both cases, depending on the STL implementation it can be hard to debug with just random errors happening each so often.
EDIT after comment: 'yes, I didn't want to return the iterator a) because its const, and b) surely it is only a local, temporary iterator? – Krakkos'
Iterators are not more or less local or temporary than any other variable and they are copyable. You can return it and the compiler will make the copy for you as it will with the pointer.
Now with the const-ness. If the caller wants to perform modifications through the returned element (whether pointer or iterator) then you should use a non-const iterator. (Just remove the 'const_' from the definition of the iterator).
Use Rescue mode with cd and mount the filesystem. Try to check if any binary files or folder are deleted. If deleted you will have to manually install the rpms to get those files back.
Thanks to a related question, I found out that I need to "checkout" the remote branch as a new local branch, and specify a new local branch name.
git checkout -b newlocalbranchname origin/branch-name
Or you can do:
git checkout -t origin/branch-name
The latter will create a branch that is also set to track the remote branch.
Update: It's been 5 years since I originally posted this question. I've learned a lot and git has improved since then. My usual workflow is a little different now.
If I want to fetch the remote branches, I simply run:
git pull
This will fetch all of the remote branches and merge the current branch. It will display an output that looks something like this:
From github.com:andrewhavens/example-project
dbd07ad..4316d29 master -> origin/master
* [new branch] production -> origin/production
* [new branch] my-bugfix-branch -> origin/my-bugfix-branch
First, rewinding head to replay your work on top of it...
Fast-forwarded master to 4316d296c55ac2e13992a22161fc327944bcf5b8.
Now git knows about my new my-bugfix-branch
. To switch to this branch, I can simply run:
git checkout my-bugfix-branch
Normally, I would need to create the branch before I could check it out, but in newer versions of git, it's smart enough to know that you want to checkout a local copy of this remote branch.
The context referenced by 'this'
keyword in JavasSript is different.
look at the following code:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<input id="btnSubmit" type="button" value="Submit" />
<script>
function disable() {
this.disabled = true;
}
var btnSubmit = document.getElementById('btnSubmit');
btnSubmit.onclick = disable();
//btnSubmit.addEventListener('click', disable, false);
</script>
</body>
</html>
What it does is really simple. when you click the button, the button will be disabled automatically.
First when you try to hook up the events in this way button.onclick = function(),
onclick event will be triggered by clicking the button, however, the button will not be disabled because there's no explicit binding between button.onclick and onclick event handler. If you debug see the 'this'
object, you can see it refers to 'window'
object.
Secondly, if you comment btnSubmit.onclick = disable();
and uncomment
//btnSubmit.addEventListener('click', disable, false);
you can see that the button is disabled because with this way there's explicit binding between button.onclick event and onclick event handler. If you debug into disable function, you can see 'this'
refers to the button control
rather than the window
.
This is something I don't like about JavaScript which is inconsistency.
Btw, if you are using jQuery($('#btnSubmit').on('click', disable);
), it uses explicit binding.
As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost';
does not work is quite simple : There is no grant called USAGE
.
The actual named grants are in the MySQL Documentation
The grant USAGE
is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user
where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE
. Running DROP USER 'phpmyadmin'@'localhost';
should work just fine. Under the hood, it's really doing this:
DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;
Therefore, the removal of a row from mysql.user
constitutes running REVOKE USAGE
, even though REVOKE USAGE
cannot literally be executed.
GenerateData is an amazing tool for this. It's also very easy to make tweaks to it because the source code is available to you. A few nice features:
If you want to print the last 10 lines, use
tail(dataset, 10)
for the first 10, you could also do
head(dataset, 10)
I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.
this is a generic example let me know if this explains the point i mentioned
CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
empName VARCHAR2(50);
empSalary NUMBER(7,2);
BEGIN
UPDATE emp
SET sal = sal + 1000
WHERE empno = 7499
RETURNING ename, sal
INTO empName, empSalary;
DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;
Note that you can use other tricks like :
-- One or more wildcard:
.../Downloads20*/*.csv
-- braces and brackets
.../Downloads201[1-5]/book.csv
.../Downloads201{11,15,19,99}/book.csv
.so
files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.
.a
files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar
command -- a predecessor of tar
that's now just used for making libraries) of the original .o object files.
.la
files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?
Static and dynamic libraries each have pros and cons.
Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.
Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.
Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.
Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.
Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.
Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.
Dynamic libraries are especially useful for system libraries, like libc
. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.
It is true that a typical IPv4 header is 20 bytes, and the UDP header is 8 bytes. However it is possible to include IP options which can increase the size of the IP header to as much as 60 bytes. In addition, sometimes it is necessary for intermediate nodes to encapsulate datagrams inside of another protocol such as IPsec (used for VPNs and the like) in order to route the packet to its destination. So if you do not know the MTU on your particular network path, it is best to leave a reasonable margin for other header information that you may not have anticipated. A 512-byte UDP payload is generally considered to do that, although even that does not leave quite enough space for a maximum size IP header.

ok, this has been answered, but I thought you might like to see my answer that calls the math.pow() function once. I guess I like keeping things DRY.
function roundIt(num, precision) {
var rounder = Math.pow(10, precision);
return (Math.round(num * rounder) / rounder).toFixed(precision)
};
It kind of puts it all together. Replace Math.round() with Math.ceil() to round-up instead of rounding-off, which is what the OP wanted.

Since version 3.6 of CKEditor you can configure if you want inline content to be automatically wrapped with tags like <p></p>
. This is the correct setting:
CKEDITOR.config.autoParagraph = false;
Source: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph
CORS in my case.
I had such response in a iOS app once. The solution was the missing Access-Control-Allow-Origin: *
in the headers.

Yes, in principe it is possible, but it doesn't come for free.
You need to create a StackTrace, and then you can have a look at the StackFrame's of the call stack.
To create global gitignore from scratch:
$ cd ~
$ touch .gitignore_global
$ git config --global core.excludesfile ~/.gitignore_global
C:/Users/User
.gitignore_global
extensionSo, I had this code:
<div class="dropdown-select-wrapper" *ngIf="contentData">
<button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
<i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
<span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
</button>
<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
<mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
{{option[contentData.optionsStructure.keyName]}}
</mat-option>
</mat-select>
</div>
Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.
<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
<mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
{{option[contentData.optionsStructure.keyName]}}
</mat-option>
</mat-select>

A rect
can't contain a text
element. Instead transform a g
element with the location of text and rectangle, then append both the rectangle and the text to it:
var bar = chart.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });
bar.append("rect")
.attr("width", x)
.attr("height", barHeight - 1);
bar.append("text")
.attr("x", function(d) { return x(d) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d) { return d; });

There are two ways to add references via VBA to your projects
1) Using GUID
2) Directly referencing the dll.
Let me cover both.
But first these are 3 things you need to take care of
a) Macros should be enabled
b) In Security settings, ensure that "Trust Access To Visual Basic Project" is checked
c) You have manually set a reference to `Microsoft Visual Basic for Applications Extensibility" object
Way 1 (Using GUID)
I usually avoid this way as I have to search for the GUID in the registry... which I hate LOL. More on GUID here.
Topic: Add a VBA Reference Library via code
Link: http://www.vbaexpress.com/kb/getarticle.php?kb_id=267
'Credits: Ken Puls
Sub AddReference()
'Macro purpose: To add a reference to the project using the GUID for the
'reference library
Dim strGUID As String, theRef As Variant, i As Long
'Update the GUID you need below.
strGUID = "{00020905-0000-0000-C000-000000000046}"
'Set to continue in case of error
On Error Resume Next
'Remove any missing references
For i = ThisWorkbook.VBProject.References.Count To 1 Step -1
Set theRef = ThisWorkbook.VBProject.References.Item(i)
If theRef.isbroken = True Then
ThisWorkbook.VBProject.References.Remove theRef
End If
Next i
'Clear any errors so that error trapping for GUID additions can be evaluated
Err.Clear
'Add the reference
ThisWorkbook.VBProject.References.AddFromGuid _
GUID:=strGUID, Major:=1, Minor:=0
'If an error was encountered, inform the user
Select Case Err.Number
Case Is = 32813
'Reference already in use. No action necessary
Case Is = vbNullString
'Reference added without issue
Case Else
'An unknown error was encountered, so alert the user
MsgBox "A problem was encountered trying to" & vbNewLine _
& "add or remove a reference in this file" & vbNewLine & "Please check the " _
& "references in your VBA project!", vbCritical + vbOKOnly, "Error!"
End Select
On Error GoTo 0
End Sub
Way 2 (Directly referencing the dll)
This code adds a reference to Microsoft VBScript Regular Expressions 5.5
Option Explicit
Sub AddReference()
Dim VBAEditor As VBIDE.VBE
Dim vbProj As VBIDE.VBProject
Dim chkRef As VBIDE.Reference
Dim BoolExists As Boolean
Set VBAEditor = Application.VBE
Set vbProj = ActiveWorkbook.VBProject
'~~> Check if "Microsoft VBScript Regular Expressions 5.5" is already added
For Each chkRef In vbProj.References
If chkRef.Name = "VBScript_RegExp_55" Then
BoolExists = True
GoTo CleanUp
End If
Next
vbProj.References.AddFromFile "C:\WINDOWS\system32\vbscript.dll\3"
CleanUp:
If BoolExists = True Then
MsgBox "Reference already exists"
Else
MsgBox "Reference Added Successfully"
End If
Set vbProj = Nothing
Set VBAEditor = Nothing
End Sub
Note: I have not added Error Handling. It is recommended that in your actual code, do use it :)

Stream is a base class, you need to create one of the specific types of streams, such as MemoryStream.
Simply use Date.getUTC*()
family of methods. On my computer (CET, UTC+01:00):
new Date().toString()
//Fri Jan 20 2012 18:05:16 GMT+0100 (CET)
new Date().getHours()
//18
new Date().getUTCHours()
//17
Notice that getUTCHours()
returns correct hour in UTC.
mylist = [0.30000000000000004, 0.5, 0.20000000000000001]
myRoundedList = [round(x,2) for x in mylist]
# [0.3, 0.5, 0.2]
There are some really good answers given already, but I wanted to throw in my two cents. Here is a very simple way to convert a view object into a entity. The simple idea is that only the properties that exist in the view model get written to the entity. This is similar to @Anik Islam Abhi's answer, but has null propagation.
public static T MapVMUpdate<T>(object updatedVM, T original)
{
PropertyInfo[] originalProps = original.GetType().GetProperties();
PropertyInfo[] vmProps = updatedVM.GetType().GetProperties();
foreach (PropertyInfo prop in vmProps)
{
PropertyInfo projectProp = originalProps.FirstOrDefault(x => x.Name == prop.Name);
if (projectProp != null)
{
projectProp.SetValue(original, prop.GetValue(updatedVM));
}
}
return original;
}
Pros
Cons
To me the simplicity and low maintenance requirements of this approach outweigh the added database call.
Firstly, application.properties in the @PropertySource should read application-test.properties
if that's what the file is named (matching these things up matters):
@PropertySource("classpath:application-test.properties ")
That file should be under your /src/test/resources
classpath (at the root).
I don't understand why you'd specify a dependency hard coded to a file called application-test.properties
. Is that component only to be used in the test environment?
The normal thing to do is to have property files with the same name on different classpaths. You load one or the other depending on whether you are running your tests or not.
In a typically laid out application, you'd have:
src/test/resources/application.properties
and
src/main/resources/application.properties
And then inject it like this:
@PropertySource("classpath:application.properties")
The even better thing to do would be to expose that property file as a bean in your spring context and then inject that bean into any component that needs it. This way your code is not littered with references to application.properties and you can use anything you want as a source of properties. Here's an example: how to read properties file in spring project?
string[] filePaths = Directory.GetFiles(@"c:\MyDir\");
foreach (string filePath in filePaths)
File.Delete(filePath);
Or in a single line:
Array.ForEach(Directory.GetFiles(@"c:\MyDir\"), File.Delete);
Even if you are sending all the right data (e.g. Selenium doesn't show up as an extension, you have a reasonable resolution/bit-depth, &c), there are a number of services and tools which profile visitor behaviour to determine whether the actor is a user or an automated system.
For example, visiting a site then immediately going to perform some action by moving the mouse directly to the relevant button, in less than a second, is something no user would actually do.
It might also be useful as a debugging tool to use a site such as https://panopticlick.eff.org/ to check how unique your browser is; it'll also help you verify whether there are any specific parameters that indicate you're running in Selenium.
As starblue says, height is just recursive. In pseudo-code:
height(node) = max(height(node.L), height(node.R)) + 1
Now height could be defined in two ways. It could be the number of nodes in the path from the root to that node, or it could be the number of links. According to the page you referenced, the most common definition is for the number of links. In which case the complete pseudo code would be:
height(node):
if node == null:
return -1
else:
return max(height(node.L), height(node.R)) + 1
If you wanted the number of nodes the code would be:
height(node):
if node == null:
return 0
else:
return max(height(node.L), height(node.R)) + 1
Either way, the rebalancing algorithm I think should work the same.
However, your tree will be much more efficient (O(ln(n))) if you store and update height information in the tree, rather than calculating it each time. (O(n))
When it says "If the balance factor of R is 1", it is talking about the balance factor of the right branch, when the balance factor at the top is 2. It is telling you how to choose whether to do a single rotation or a double rotation. In (python like) Pseudo-code:
if balance factor(top) = 2: // right is imbalanced
if balance factor(R) = 1: //
do a left rotation
else if balance factor(R) = -1:
do a double rotation
else: // must be -2, left is imbalanced
if balance factor(L) = 1: //
do a left rotation
else if balance factor(L) = -1:
do a double rotation
I hope this makes sense
Take a look here in order to get started: http://instagram.com/developer/
and then in order to retrieve pictures by tag, look here: http://instagram.com/developer/endpoints/tags/
Getting tags from Instagram doesn't require OAuth, so you can make the calls via these URLs:
GET IMAGES
https://api.instagram.com/v1/tags/{tag-name}/media/recent?access_token={TOKEN}
SEARCH
https://api.instagram.com/v1/tags/search?q={tag-query}&access_token={TOKEN}
TAG INFO
https://api.instagram.com/v1/tags/{tag-name}?access_token={TOKEN}
this will be work in my case when in tabs i switch from one fragment to another fragments

mImm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
mImm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);

Log.e(TAG, "setUserVisibleHint: ", e);

Is there a way to declare first and then initialize an array in C?
There is! but not using the method you described.
You can't initialize with a comma separated list, this is only allowed in the declaration. You can however initialize with...
myArray[0] = 1;
myArray[1] = 2;
...
or
for(int i = 1; i <= SIZE; i++)
{
myArray[i-1] = i;
}
As has been explained by many, object
defines a singleton instance. The one thing in the answers here that I believe is left out is that object
serves several purposes.
It can be the companion object to a class
/trait
, containing what might be considered static methods or convenience methods.
It can act much like a module, containing related/subsidiary types and definitions, etc.
It can implement an interface by extending a class
or one or more trait
s.
It can represent a case of a sealed trait
that contains no data. In this respect, it's often considered more correct than a case class
with no parameters. The special case of a sealed trait
with only case object
implementors is more or less the Scala version of an enum.
It can act as evidence for implicit
-driven logic.
It introduces a singleton type.
It's a very powerful and general construct. What can be very confusing to Scala beginners is that the same construct can have vastly different uses. And an object
can serve many of these different uses all at once, which can be even more confusing.
For those of you complaining about "the submenus don't drop down", I solved it this way, which looks clean to me:
1) Besides your
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b>
</a>
put a new
<a class="dropdown-toggle"><b class="caret"></b></a>
and remove the <b class="caret"></b>
tag, so it will look like
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown</a><a class="dropdown-toggle"><b class="caret"></b></a>
2) Style them with the following css rules:
.caret1 {
position: absolute !important; top: 0; right: 0;
}
.dropdown-toggle.disabled {
padding-right: 40px;
}
The style in .caret1 class is for positioning it absolutely inside your li
, at the right corner.
The second style is for adding some padding to the right of the dropdown to place the caret, preventing overlapping the text of the menu item.
Now you have a nice responsive menu item which looks nice both in desktop and mobile versions and that is both clickable and dropdownable depending on whether you click on the text or on the caret.
the third way is to base64 encode the image and place it in a data:
url
example:
<img src="data:image/png;base64,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" width="32" height="32">
Ansible has a version_compare
filter since 1.6.
You can do something like below in when
conditional:
when: ansible_distribution_version | version_compare('12.04', '>=')
This will give you support for major & minor versions comparisons and you can compare versions using operators like:
<, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne
You can find more information about this here: Ansible - Version comparison filters
Otherwise if you have really simple case you can use what @ProfHase85 suggested
I was facing the same issue, I was using tomcat 8.5 with Java 10.Finally I installed Java 8(1.8.0_171) and it's working fine without any issues
For the sake of the example lets assume you have a class Person
with just a name
.
private class Person {
public String name;
public Person(String name) {
this.name = name;
}
}
My personal favourite as to the great JSON serialisation / de-serialisation of objects.
Gson g = new Gson();
Person person = g.fromJson("{\"name\": \"John\"}", Person.class);
System.out.println(person.name); //John
System.out.println(g.toJson(person)); // {"name":"John"}
Update
If you want to get a single attribute out you can do it easily with the Google library as well:
JsonObject jsonObject = new JsonParser().parse("{\"name\": \"John\"}").getAsJsonObject();
System.out.println(jsonObject.get("name").getAsString()); //John
If you don't need object de-serialisation but to simply get an attribute, you can try org.json (or look GSON example above!)
JSONObject obj = new JSONObject("{\"name\": \"John\"}");
System.out.println(obj.getString("name")); //John
ObjectMapper mapper = new ObjectMapper();
Person user = mapper.readValue("{\"name\": \"John\"}", Person.class);
System.out.println(user.name); //John
return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
This sample shows how to read a string from a MemoryStream, in which I've used a serialization (using DataContractJsonSerializer), pass the string from some server to client, and then, how to recover the MemoryStream from the string passed as parameter, then, deserialize the MemoryStream.
I've used parts of different posts to perform this sample.
Hope that this helps.

Yahoo's api provides a CSV dump:
Example: http://finance.yahoo.com/d/quotes.csv?s=msft&f=price
I'm not sure if it is documented or not, but this code sample should showcase all of the features (namely the stat types [parameter f in the query string]. I'm sure you can find documentation (official or not) if you search for it.
http://www.goldb.org/ystockquote.html
Edit
I found some unofficial documentation:
Strings are immutable, so using
public string GenerateString()
{
return
"abc" +
"def";
}
will slow you performance - each of those values is a string literal which must be concatenated at runtime - bad news if you reuse the method/property/whatever alot...
Store your string literals in resources is a good idea...
public string GenerateString()
{
return Resources.MyString;
}
That way it is localisable and the code is tidy (although performance is pretty terrible).
If you use Windows 10 and has Windows Subsystem for Linux (WSL), it can be easily done by typing "file " from the shell.
For example:
$ file code.cpp
code.cpp: C source, UTF-8 Unicode (with BOM) text, with CRLF line terminators
jq '.users[]|.first,.last' | paste - -

Look before you leap (LBYL):
if idx < len(array):
array[idx]
else:
# handle this
Easier to ask forgiveness than permission (EAFP):
try:
array[idx]
except IndexError:
# handle this
In Python, EAFP seems to be the popular and preferred style. It is generally more reliable, and avoids an entire class of bugs (time of check vs. time of use). All other things being equal, the try
/except
version is recommended - don't see it as a "last resort".
This excerpt is from the official docs linked above, endorsing using try/except for flow control:
This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements.
byte b = (byte)0xC8;
int v1 = b; // v1 is -56 (0xFFFFFFC8)
int v2 = b & 0xFF // v2 is 200 (0x000000C8)
Most of the time v2 is the way you really need.
Not sure if this answers your question or not. Sorry if not
To get the error reported from the mysql database about your query you need to use your connection object as the focus.
so:
echo $mysqliDatabaseConnection->error
would echo the error being sent from mysql about your query.
Hope that helps
In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml
), you can do so by just putting an array of mappings in the @WebFilter
annotation:
/**
* Filter implementation class LoginFilter
*/
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
...
And just as an FYI, this same thing works for servlets using the servlet annotation too:
/**
* Servlet implementation class LoginServlet
*/
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
...
Open eclipse.ini
in the installation directory, and observe the line with text:
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.
If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.
If you only want to change your last message you should use the --only
flag or its shortcut -o
with commit --amend
:
git commit --amend -o -m "New commit message"
This ensures that you don't accidentally enhance your commit with staged stuff. Of course it's best to have a proper $EDITOR
configuration. Then you can leave the -m
option out, and Git will pre-fill the commit message with the old one. In this way it can be easily edited.
Well, you could erase()
the first character too (note that erase()
modifies the string):
m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);
But in this case, a simpler way is to take a substring:
m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);
Be careful to validate that the string actually has at least two characters in it first...
One way would be to create all commits ever made to patches. checkout the initial commit and then apply the patches in order after reading.
use git format-patch <initial revision>
and then git checkout <initial revision>
.
you should get a pile of files in your director starting with four digits which are the patches.
when you are done reading your revision just do git apply <filename>
which should look like
git apply 0001-*
and count.
But I really wonder why you wouldn't just want to read the patches itself instead? Please post this in your comments because I'm curious.
the git manual also gives me this:
git show next~10:Documentation/README
Shows the contents of the file Documentation/README as they were current in the 10th last commit of the branch next.
you could also have a look at git blame filename
which gives you a listing where each line is associated with a commit hash + author.
You can use the following code to test if display
is equivalent to none
:
if ($(element).css('display') === 'none' ){
// do the stuff
}
You have to look I the folder C:\Program Files\MySQL\MySQL Server 5.5
but there is a problem. When you perform an MSI install of MySQL, my.ini is not created. There will be sample .ini files in that folder. In order to use one of them, say my-medium.ini
, you need to do the following before a MySQL restart:
cd C:\Program Files\MySQL\MySQL Server 5.5
copy my-medium.ini my.ini
net stop mysql
net start mysql
Once, you do this, my.ini
can be read by C:\Program Files\MySQL\MySQL Server 5.5\bin\mysql.exe
.
You'll get converting errors with:
cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();
Use instead:
string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
found = true;
} else {
found = false;
}
Getting only the "major" build #:
java -version 2>&1 | head -n 1 | awk -F'["_.]' '{print $3}'
Sounds like you're working in just one table so something like this:
update your_table
set B = A
where B is null
In addition to the above great answers using Threads, in case you have to use your main thread or prefer an async approach - I wrapped a short class around aio_timers Timer class (to enable repeating)
import asyncio
from aio_timers import Timer
class RepeatingAsyncTimer():
def __init__(self, interval, cb, *args, **kwargs):
self.interval = interval
self.cb = cb
self.args = args
self.kwargs = kwargs
self.aio_timer = None
self.start_timer()
def start_timer(self):
self.aio_timer = Timer(delay=self.interval,
callback=self.cb_wrapper,
callback_args=self.args,
callback_kwargs=self.kwargs
)
def cb_wrapper(self, *args, **kwargs):
self.cb(*args, **kwargs)
self.start_timer()
from time import time
def cb(timer_name):
print(timer_name, time())
print(f'clock starts at: {time()}')
timer_1 = RepeatingAsyncTimer(interval=5, cb=cb, timer_name='timer_1')
timer_2 = RepeatingAsyncTimer(interval=10, cb=cb, timer_name='timer_2')
clock starts at: 1602438840.9690785

This might work for you:
sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1
I found the problem to this... due to a incorrect/failed reference in .rdl to data conns etc. Also found that BIDS wasn't happy about having spaces in some of the project/report filenames... so anyone facing this issue make sure you have no spaces in your naming and check your rdl files, connections, everything for failed/out of date references! Visual Studio seems crap at keeping all of it's references up to date... god forbid you have to rename anything!

I understand you asked specifically about SQLite, but maybe HSQL database would be a better fit with Java. It is written in Java itself, runs in the JVM, supports in-memory tables etc. and all that features make it quite usable for prototyping and unit-testing.

You can use this function:
int arraySize(char array[])
{
int cont = 0;
for (int i = 0; array[i] != 0; i++)
cont++;
return cont;
}
With literal syntax you can check as follows
static const NSString* kKeyToCheck = @"yourKey"
if (xyz[kKeyToCheck])
NSLog(@"Key: %@, has Value: %@", kKeyToCheck, xyz[kKeyToCheck]);
else
NSLog(@"Key pair do not exits for key: %@", kKeyToCheck);

RadPHP (previously known as Delphi for PHP) is the best.
Why do you need to encrypt the database? The user could easily disassemble your program and figure out the key. If you're encrypting it for network transfer, then consider using PGP instead of squeezing an encryption layer into a database layer.
This is probably faster?:
n = len(predictions)
rmse = np.linalg.norm(predictions - targets) / np.sqrt(n)
You can do it by creating a new table, copy all the data over, drop the old table, then renaming the new one to replace the old one.
You could also add new columns to the table, copy the column by column data over, drop the old columns, then rename new columns to match the old ones. A simple example below: http://sqlfiddle.com/#!3/67af4/1
CREATE TABLE TestTable (
Column1 INT,
Column2 VARCHAR(255)
);
GO
insert into TestTable values(1, 'Test1');
insert into TestTable values(2, 'Test2');
GO
select * from TestTable;
GO
ALTER TABLE TestTable ADD Column2_NEW VARCHAR(255);
ALTER TABLE TestTable ADD Column1_NEW INT;
GO
update TestTable
set Column1_NEW = Column1,
Column2_NEW = Column2;
GO
ALTER TABLE TestTable DROP COLUMN Column1;
ALTER TABLE TestTable DROP COLUMN Column2;
GO
sp_rename 'TestTable.Column1_NEW', 'Column1', 'COLUMN';
GO
sp_rename 'TestTable.Column2_NEW', 'Column2', 'COLUMN';
GO
select * from TestTable;

See excerpt from official documentation for containment
option:
containment
Default:
false
Constrains dragging to within the bounds of the specified element or region.
Multiple types supported:
- Selector: The draggable element will be contained to the bounding box of the first element found by the selector. If no element is found, no containment will be set.
- Element: The draggable element will be contained to the bounding box of this element.
- String: Possible values:
"parent"
,"document"
,"window"
.- Array: An array defining a bounding box in the form
[ x1, y1, x2, y2 ]
.Code examples:
Initialize the draggable with thecontainment
option specified:$( ".selector" ).draggable({ containment: "parent" });
Get or set the
containment
option, after initialization:// Getter var containment = $( ".selector" ).draggable( "option", "containment" ); // Setter $( ".selector" ).draggable( "option", "containment", "parent" );

On macOS the docker
binary is only a client and you cannot use it to run the docker daemon, because Docker daemon uses Linux-specific kernel features, therefore you can’t run Docker natively in OS X. So you have to install docker-machine
in order to create VM and attach to it.
docker-machine
on macOSIf you don't have docker-machine
command yet, install it by using one of the following methods:
brew install docker-machine docker
.Manually from Releases page:
$ curl -L https://github.com/docker/machine/releases/download/v0.16.1/docker-machine-`uname -s`-`uname -m` >/usr/local/bin/docker-machine
$ chmod +x /usr/local/bin/docker-machine
See: Get started with Docker for Mac.
docker-machine
relies on VirtualBox being installed and will fail if this isn't the case. If you already have VirtualBox, you can skip this step.
brew cask install virtualbox
You will need to actively accept loading the Virtualbox kernel extension in the OS X Security panel and then proceed to restart the machine for the next commands not to fail with Error: VBoxNetAdpCtl: Error while adding new interface
docker-machine
on macOSCreate a default
machine (if you don't have one, see: docker-machine ls
):
docker-machine create --driver virtualbox default
Then set-up the environment for the Docker client:
eval "$(docker-machine env default)"
Then double-check by listing containers:
docker ps
See: Get started with Docker Machine and a local VM.

In my case, I had this problem in my spec file, while running my tests.

Here is some interesting information about SET / SELECT
- SET is the ANSI standard for variable assignment, SELECT is not.
- SET can only assign one variable at a time, SELECT can make multiple assignments at once.
- If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
- When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
- As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
One could simply use this
MyControl.Margin = new System.Windows.Thickness(10, 0, 5, 0);
You can use .Length
== 0 if the length is empty and the array exists, but are you sure it's not null?
I think I have found a sort of work around for the OP question - instead of a transition beginning 'on.load' of the page - I found that using an animation for an opacity fade in had the same effect, (I was looking for the same thing as OP).
So I wanted to have the body text fade in from white(same as site background) to black text colour on page load - and I've only been coding since Monday so I was looking for an 'on.load' style thing code, but don't know JS yet - so here is my code that worked well for me.
#main p {
animation: fadein 2s;
}
@keyframes fadein {
from { opacity: 0}
to { opacity: 1}
}
And for whatever reason, this doesn't work for .class
only #id
's(at least not on mine)
Hope this helps - as I know this site helps me a lot!
In my situation, I had \r\n
in my single-quoted dictionary strings. I replaced all instances of \r

with \\n
and it fixed my issue, properly returning escaped line breaks in the eval'ed dict.
ast.literal_eval(my_str.replace('\r','\\r').replace('\n','\\n'))

If you want to list all the files currently being tracked under the branch master
, you could use this command:
git ls-tree -r master --name-only
If you want a list of files that ever existed (i.e. including deleted files):
git log --pretty=format: --name-only --diff-filter=A | sort - | sed '/^$/d'
\n
This means insert a newline in the text at this point.
Just example
System.out.println("hello\nworld");
Output:
hello
world
import java.lang.String;
This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).
Through trial and error, it seems if the user was originally created "without login" then this query
select * from sys.database_principals
will show authentication_type = 0 (NONE).
Apparently these users cannot be re-linked to any login (pre-existing or new, SQL or Windows) since this command:
alter user [TempUser] with login [TempLogin]
responds with the Remap Error "Msg 33016" shown in the question.
Also these users do not show up in classic (deprecating) SP report:
exec sp_change_users_login 'Report'
If anyone knows a way around this or how to change authentication_type, please comment.
By default there are no constraints on the foreign key, foreign key can be null and duplicate.
while creating a table / altering the table, if you add any constrain of uniqueness or not null then only it will not allow the null/ duplicate values.
Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup
$("#div").html($("#input").val());
For general updating table1 specific colom based on Table2 specific colom, below query works perfectly...
UPDATE table 1
SET Col 2 = t2.Col2,
Col 3 = t2.Col3
FROM table1 t1
INNER JOIN table 2 t2 ON t1.Col1 = t2.col1
In Computer Science, an Alphanumeric value often means the first character is not a number but is an alphabet or underscore. Thereafter the character can be 0-9
, A-Z
, a-z
, or underscore (_
).
Here is how you would do that:
Tested under php:
$regex = '/^[A-Za-z_][A-Za-z\d_]*$/'
or take this
^[A-Za-z_][A-Za-z\d_]*$
and place it in your development language.
In my dimens.xml I have
<dimen name="test">48dp</dimen>
In code If I do
int valueInPixels = (int) getResources().getDimension(R.dimen.test)
this will return 72 which as docs state is multiplied by density of current phone (48dp x 1.5 in my case)
exactly as docs state :
Retrieve a dimensional for a particular resource ID. Unit conversions are based on the current DisplayMetrics associated with the resources.
so if you want exact dp value just as in xml just divide it with DisplayMetrics density
int dp = (int) (getResources().getDimension(R.dimen.test) / getResources().getDisplayMetrics().density)
dp will be 48 now
As a NOT TO DO - Another way would be to use:
divControl.Attributes.Add("style", "height: number");
But don't use this as its messy and the answer by AviewAnew is the correct way.
In addition to other issues caused by failing to quote, -n
and -e
can be consumed by echo
as arguments. (Only the former is legal per the POSIX spec for echo
, but several common implementations violate the spec and consume -e
as well).
To avoid this, use printf
instead of echo
when details matter.
Thus:
$ vars="-e -n -a"
$ echo $vars # breaks because -e and -n can be treated as arguments to echo
-a
$ echo "$vars"
-e -n -a
However, correct quoting won't always save you when using echo
:
$ vars="-n"
$ echo $vars
$ ## not even an empty line was printed
...whereas it will save you with printf
:
$ vars="-n"
$ printf '%s\n' "$vars"
-n

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

The file you are looking for is at,
Microsoft VS Code\resources\app\extensions\theme-defaults\themes
on Windows and search for filename dark_vs.json
to locate it on any other system.

With new versions of VSCode you don't need to hunt for the settings file to customize the theme. Now you can customize your color theme with the workbench.colorCustomizations
and editor.tokenColorCustomizations
user settings. Documentation on the matter can be found here.
int
is a primitive data type while Integer
is a Reference or Wrapper Type (Class) in Java.
after java 1.5
which introduce the concept of autoboxing and unboxing you can initialize both int
or Integer
like this.
int a= 9
Integer a = 9 // both valid After Java 1.5.
why
Integer.parseInt("1");
but notint.parseInt("1");
??
Integer
is a Class defined in jdk
library and parseInt()
is a static method belongs to Integer
Class
So, Integer.parseInt("1");
is possible in java. but int
is primitive type (assume like a keyword) in java. So, you can't call parseInt()
with int
.
