calling finish in onCreate() will not call onDestroy() directly as @prakash said. The finish()
operation will not even begin until you return control to Android.
Calling finish() in onCreate(): onCreate() -> onStart() -> onResume(). If user exit the app will call -> onPause() -> onStop() -> onDestroy()
Calling finish() in onStart() : onCreate() -> onStart() -> onStop() -> onDestroy()
Calling finish() in onResume(): onCreate() -> onStart() -> onResume() -> onPause() -> onStop() -> onDestroy()
For further reference check look at this oncreate continuous after finish & about finish()
I'd suggest a different approach to this question. Maybe it's not the most efficient one, but I think it's the easiest to apply and requires very little code. Writing the next code in your first activity (log in activity, in my case) won't let the user go back to previously launched activities after logging out.
@Override
public void onBackPressed() {
// disable going back to the MainActivity
moveTaskToBack(true);
}
I'm assuming that LoginActivity is finished just after the user logs in, so that he can't go back to it later by pressing the back button. Instead, the user must press a log out button inside the app in order to log out properly. What this log out button would implement is a simple intent as follows:
Intent intent = new Intent(this, LoginActivity.class);
startActivity(intent);
finish();
All suggestions are welcome.
It is crazy that no one has mentioned this elegant solution. This should be the accepted answer.
SplashActivity -> AuthActivity -> DashActivity
if (!sessionManager.isLoggedIn()) {
Intent intent = new Intent(context, AuthActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
context.startActivity(intent);
finish();
} else {
Intent intent = new Intent(context, DashActivity.class);
context.startActivity(intent);
finish();
}
The key here is to use intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
for the intermediary Activity
. Once that middle link is broken, the DashActivity
will the first and last in the stack.
android:noHistory="true"
is a bad solution, as it causes problems when relying on the Activity
as a callback e.g onActivityResult
. This is the recommended solution and should be accepted.
Here's a script that will use the Google API to acquire the users postal code and populate an input field.
function postalCodeLookup(input) {
var head= document.getElementsByTagName('head')[0],
script= document.createElement('script');
script.src= '//maps.googleapis.com/maps/api/js?sensor=false';
head.appendChild(script);
script.onload = function() {
if (navigator.geolocation) {
var a = input,
fallback = setTimeout(function () {
fail('10 seconds expired');
}, 10000);
navigator.geolocation.getCurrentPosition(function (pos) {
clearTimeout(fallback);
var point = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
new google.maps.Geocoder().geocode({'latLng': point}, function (res, status) {
if (status == google.maps.GeocoderStatus.OK && typeof res[0] !== 'undefined') {
var zip = res[0].formatted_address.match(/,\s\w{2}\s(\d{5})/);
if (zip) {
a.value = zip[1];
} else fail('Unable to look-up postal code');
} else {
fail('Unable to look-up geolocation');
}
});
}, function (err) {
fail(err.message);
});
} else {
alert('Unable to find your location.');
}
function fail(err) {
console.log('err', err);
a.value('Try Again.');
}
};
}
You can adjust accordingly to acquire different information. For more info, check out the Google Maps API documentation.
To make it work you should change the following variables in your php.ini:
; display_errors
; Default Value: On
; Development Value: On
; Production Value: Off
; display_startup_errors
; Default Value: On
; Development Value: On
; Production Value: Off
; error_reporting
; Default Value: E_ALL & ~E_NOTICE
; Development Value: E_ALL | E_STRICT
; Production Value: E_ALL & ~E_DEPRECATED
; html_errors
; Default Value: On
; Development Value: On
; Production value: Off
; log_errors
; Default Value: On
; Development Value: On
; Production Value: On
Search for them as they are already defined and put your desired value. Then restart your apache2 server and everything will work fine. Good luck!
If your only requirement is to print the third field of every line, with each field delimited by a comma, you can use cut:
cut -d, -f3 file
-d,
sets the delimiter to a comma-f3
specifies that only the third field is to be printedThe "python-dateutil" (external extension) is a good solution, but you can do it with build-in Python modules (datetime and datetime)
I made a short and simple code, to solve it (dealing with year, month and day)
(running: Python 3.8.2)
from datetime import datetime
from calendar import monthrange
# Time to increase (in months)
inc = 12
# Returns mod of the division for 12 (months)
month = ((datetime.now().month + inc) % 12) or 1
# Increase the division by 12 (months), if necessary (+ 12 months increase)
year = datetime.now().year + int((month + inc) / 12)
# (IF YOU DON'T NEED DAYS,CAN REMOVE THE BELOW CODE)
# Returns the same day in new month, or the maximum day of new month
day = min(datetime.now().day,monthrange(year, month)[1])
print("Year: {}, Month: {}, Day: {}".format(year, month, day))
I was uninstalled compass 1.0.1 and install compass 0.12.7, this fix problem for me
$ sudo gem uninstall compass
$ sudo gem install compass -v 0.12.7
In response to @A.M.K's question about how to do transitions without jQuery. A very simple example I threw together. If I had time to think this through some more, I might be able to eliminate the JavaScript code altogether:
<style>
body {
background-color: red;
transition: background-color 2s ease-in;
}
</style>
<script>
window.onload = function() {
document.body.style.backgroundColor = '#00f';
}
</script>
<body>
<p>test</p>
</body>
As of currently (September 2014) I would recommend using NSInteger/CGFloat
when interacting with iOS API's etc if you are also building your app for arm64.
This is because you will likely get unexpected results when you use the float
, long
and int
types.
EXAMPLE: FLOAT/DOUBLE vs CGFLOAT
As an example we take the UITableView delegate method tableView:heightForRowAtIndexPath:
.
In a 32-bit only application it will work fine if it is written like this:
-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 44;
}
float
is a 32-bit value and the 44 you are returning is a 32-bit value.
However, if we compile/run this same piece of code in a 64-bit arm64 architecture the 44 will be a 64-bit value. Returning a 64-bit value when a 32-bit value is expected will give an unexpected row height.
You can solve this issue by using the CGFloat
type
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 44;
}
This type represents a 32-bit float
in a 32-bit environment and a 64-bit double
in a 64-bit environment. Therefore when using this type the method will always receive the expected type regardless of compile/runtime environment.
The same is true for methods that expect integers.
Such methods will expect a 32-bit int
value in a 32-bit environment and a 64-bit long
in a 64-bit environment. You can solve this case by using the type NSInteger
which serves as an int
or a long
based on the compile/runtime environemnt.
$ echo 'hello:world:again' |sed 's/:.*//'
hello
$('#selected ul').children().length;
or even better
$('#selected li').length;
How about if you use grep instead of find?
ls | grep .txt$ > out.txt
Now you can read this file and the filenames are in the form of a list.
By default you will get a core file. Check to see that the current directory of the process is writable, or no core file will be created.
As Jose answered, screen -d -r
should do the trick. This is a combination of two commands, as taken from the man page.
screen -d
detaches the already-running screen session, and screen -r
reattaches the existing session. By running screen -d -r
, you force screen to detach it and then resume the session.
If you use the capital -D -RR
, I quote the man page because it's too good to pass up.
Attach here and now. Whatever that means, just do it.
Note: It is always a good idea to check the status of your sessions by means of "screen -list".
Open the project file and not the solution. The project will be converted by the Wizard, and after converted, when you build the project, a new Solution will be generated as a VS2010 one.
Yet another option is to have, in Ticket
, one column specifying the owning entity type (User
or Group
), second column with referenced User
or Group
id and NOT to use Foreign Keys but instead rely on a Trigger to enforce referential integrity.
Two advantages I see here over Nathan's excellent model (above):
You can split on a range of characters using the re
module.
>>> import re
>>> r = re.compile('[ \t\n\r:]+')
>>> r.split("abc:def ghi")
['abc', 'def', 'ghi']
Just adding information which is not present in other answers.
/proc/self/cmdline
is availableIf you are running in an environment which provides procfs and therefore has the /proc
file system available (which means this is not a portable solution), you can have Java read /proc/self/cmdline
in order to restart itself, like this:
public static void restart() throws IOException {
new ProcessBuilder(getMyOwnCmdLine()).inheritIO().start();
}
public static String[] getMyOwnCmdLine() throws IOException {
return readFirstLine("/proc/self/cmdline").split("\u0000");
}
public static String readFirstLine(final String filename) throws IOException {
try (final BufferedReader in = new BufferedReader(new FileReader(filename))) {
return in.readLine();
}
}
On systems with /proc/self/cmdline
available, this probably is the most elegant way of how to "restart" the current Java process from Java. No JNI involved, and no guessing of paths and stuff required. This will also take care of all JVM options passed to the java
binary. The command line will be exactly identical to the one of the current JVM process.
Many UNIX systems including GNU/Linux (including Android) nowadays have procfs However on some like FreeBSD, it is deprecated and being phased out. Mac OS X is an exception in the sense that it does not have procfs. Windows also does not have procfs. Cygwin has procfs but it's invisible to Java because it's only visible to applications using the Cygwin DLLs instead of Windows system calls, and Java is unaware of Cygwin.
ProcessBuilder.inheritIO()
The default is that stdin
/ stdout
/ stderr
(in Java called System.in
/ System.out
/ System.err
) of the started Process are set to pipes which allow the currently running process to communicate with the newly started process. If you want to restart the current process, this is most likely not what you want. Instead you would want that stdin
/ stdout
/ stderr
are the same as those of the current VM. This is called inherited. You can do so by calling inheritIO()
of your ProcessBuilder
instance.
A frequent use case of a restart()
function is to restart the application after an update. The last time I tried this on Windows this was problematic. When overwrote the application's .jar
file with the new version, the application started to misbehave and giving exceptions about the .jar
file. I'm just telling, in case this is your use case. Back then I solved the issue by wrapping the application in a batch file and using a magic return value from System.exit()
that I queried in the batch file and had the batch file restart the application instead.
I prefer using another library called Pechkin because it is able to convert non trivial HTML (that also has CSS classes). This is possible because this library uses the WebKit layout engine that is also used by browsers like Chrome and Safari.
I detailed on my blog my experience with Pechkin: http://codeutil.wordpress.com/2013/09/16/convert-html-to-pdf/
i make it work with a scope definition
public function pagar(\Illuminate\Http\Request $request) { //
I know this is an old post, but just thought I'd share our solution. In the quest for shortest code (doesn't everyone just love terse regex), one could instead use:
title = title.replace(/(^\s+|\s+$)/g, '');
BTW: I ran this same test through the link shared above blog.stevenlevithan.com -- Faster JavaScript Trim and this pattern beat all the other HANDS down!
Using IE8, added test as test13. The results were:
Original length: 226002
trim1: 110ms (length: 225994)
trim2: 79ms (length: 225994)
trim3: 172ms (length: 225994)
trim4: 203ms (length:225994)
trim5: 172ms (length: 225994)
trim6: 312ms (length: 225994)
trim7: 203ms (length: 225994)
trim8: 47ms (length: 225994)
trim9: 453ms (length: 225994)
trim10: 15ms (length: 225994)
trim11: 16ms (length: 225994)

trim13: 0ms (length: 226002)
@echo off
set /p input="Write something, it will be used in the command "echo""
echo %input%
pause
if i get what you want, this works fine. you can use %input% in other commands too.
@echo off
echo Write something, it will be used in the command "echo"
set /p input=""
cls
echo %input%
pause
You could use LINQBridge (MIT Licensed) to add support for lambda expressions to C# 2.0:
With Studio's multi-targeting and LINQBridge, you'll be able to write local (LINQ to Objects) queries using the full power of the C# 3.0 compiler—and yet your programs will require only Framework 2.0.
In Acrobat, click on the "Advanced" tab, then click on "Enable Features in Adobe Reader." This should do the trick.
myClub.distance = Console.ReadLine();
should be
myClub.mydistance = Console.ReadLine();
use your public properties that you have defined for others as well instead of the protected field members.
Sure, you can use equals
if you want to go along with the crowd, but if you really want to amaze your fellow programmers check for inequality like this:
if ("success" != statusCheck.intern())
intern method is part of standard Java String API.
I just figured. You need to add a shared folder using VirtualBox before you access it with the guest.
Click "Device" in the menu bar--->Shared File--->add a directory and name it
then in the guest terminal, use:
sudo mount -t vboxsf myFileName ~/destination
Dont directly refer to the host directory
Building slightly upon the answers here, I've wrapped this process up as a simple Bash script, which could of course be used as a Git alias as well.
The important addition to me is that this prompts me to run unit tests before committing and passes in the current branch name by default.
$ git_push_new_branch.sh
Have you run your unit tests yet? If so, pass OK or a branch name, and try again
usage: git_push_new_branch {OK|BRANCH_NAME}
e.g.
git_push_new_branch -> Displays prompt reminding you to run unit tests
git_push_new_branch OK -> Pushes the current branch as a new branch to the origin
git_push_new_branch MYBRANCH -> Pushes branch MYBRANCH as a new branch to the origin
function show_help()
{
IT=$(cat <<EOF

You can hit your page at
localhost:3000 or IPaddress:3000
There is also a different approach.. and this would work for tables that aren't static... basically use <th>
instead of <td>
for that column:
<style type="text/css">
table td { border: 1px solid black; }
table th { border: 0px; }
<style>
<table>
<tbody>
<tr>
<td>One</td>
<td>Two</td>
<td>Three</td>
<td>Four</td>
<th>Five</th>
</tr>
<tr>
<td>One</td>
<td>Two</td>
<td>Three</td>
<td>Four</td>
<th>Five</th>
</tr>
</tbody>
</table>
You can use getContent() method on Request object.
$request->getContent() //json as a string.
Usually you would be interested in also having some structure to your data in the receiving end:
json_encode($result)
This will preserve the array keys as well.
Do remember that json_encode only works on utf8 -encoded data.
I've used Sothink SWF decompiler a couple of times, the only problem is that as project gets more complex, the output of decompiler gets harder to compile back again. But it ensures that you can get your .as files most of the time, compilable fla is a question.
This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):
SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC
This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.
Use
git commit --amend
To understand it in detail, an excellent post is 4. Rewriting Git History. It also talks about when not to use git commit --amend
.
Switch -J
only works on newer systems. The universal command is:
To make .tar.xz archive
tar cf - directory/ | xz -z - > directory.tar.xz
Explanation
tar cf - directory
reads directory/ and starts putting it to TAR format. The output of this operation is generated on the standard output.
|
pipes standard output to the input of another program...
... which happens to be xz -z -
. XZ is configured to compress (-z
) the archive from standard input (-
).
You redirect the output from xz
to the tar.xz
file.
In order to work with newer versions of Windows' policy of only allowing read access by default to the Program Files folder (unless you prompt for elevation with UAC, but that's another topic...), your application will have a settings folder under %userprofile%\appdata\local
or %userprofile%\Local Settings\Application Data
depending on which version of Windows you're running, for settings that are user specific. If you store settings for all users, then they'll be in the corresponding folder under C:\users
or C:\Documents and Settings
for all user profiles (ex: C:\users\public\appdata\local
).
I have tried so many solutions from this post and ended up with the below solution. This is full proof solution unless you need to drop shadow on a clear color view.
- (void)addShadowWithRadius:(CGFloat)shadowRadius withOpacity:(CGFloat)shadowOpacity withOffset:(CGSize)shadowOffset withColor:(UIColor *)shadowColor withCornerradius:(CGFloat)cornerRadius
{
UIView *viewShadow = [[UIView alloc]initWithFrame:self.frame];
viewShadow.backgroundColor = [UIColor whiteColor];
viewShadow.layer.shadowColor = shadowColor.CGColor;
viewShadow.layer.shadowOffset = shadowOffset;
viewShadow.layer.shadowRadius = shadowRadius;
viewShadow.layer.shadowOpacity = shadowOpacity;
viewShadow.layer.cornerRadius = cornerRadius;
viewShadow.layer.masksToBounds = NO;
[self.superview insertSubview:viewShadow belowSubview:self];
[viewShadow setTranslatesAutoresizingMaskIntoConstraints:NO];
[self.superview addConstraint:[NSLayoutConstraint constraintWithItem:viewShadow attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:self attribute:NSLayoutAttributeWidth multiplier:1.0 constant:0]];
[self.superview addConstraint:[NSLayoutConstraint constraintWithItem:viewShadow attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:self attribute:NSLayoutAttributeHeight multiplier:1.0 constant:0]];
[self.superview addConstraint:[NSLayoutConstraint constraintWithItem:viewShadow attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:viewShadow attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0]];
[self.superview addConstraint:[NSLayoutConstraint constraintWithItem:viewShadow attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:viewShadow attribute:NSLayoutAttributeCenterY multiplier:1.0 constant:0]];
[self layoutIfNeeded];
self.layer.cornerRadius = cornerRadius;
self.layer.masksToBounds = YES;
}
Using static
will not help your case.
Using synchronize
locks a variable when it is in use by another thread.
You should use volatile
keyword to keep the variable updated among all threads.
Using volatile is yet another way (like synchronized, atomic wrapper) of making class thread safe. Thread safe means that a method or class instance can be used by multiple threads at the same time without any problem.
First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.
Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.
Here's how you should do it with all the suggestions above:
public enum States {
...
MASSACHUSETTS("Massachusetts", "MA", true),
MICHIGAN ("Michigan", "MI", false),
...; // all 50 of those
private final String full;
private final String abbr;
private final boolean originalColony;
private States(String full, String abbr, boolean originalColony) {
this.full = full;
this.abbr = abbr;
this.originalColony = originalColony;
}
public String getFullName() {
return full;
}
public String getAbbreviatedName() {
return abbr;
}
public boolean isOriginalColony(){
return originalColony;
}
}
It is actually possible to do it using .NET regular expressions, but it is not trivial, so read carefully.
You can read a nice article here. You also may need to read up on .NET regular expressions. You can start reading here.
Angle brackets <>
were used because they do not require escaping.
The regular expression looks like this:
<
[^<>]*
(
(
(?<Open><)
[^<>]*
)+
(
(?<Close-Open>>)
[^<>]*
)+
)*
(?(Open)(?!))

I am late to this one by a while, but I'm going to blow your mind, ready?
The reason this is happening, is because you are calling bootstrap in, after you are calling jquery-ui in.
Literally, swap the two so that instead of:
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script src="js/bootstrap.min.js"></script>
it becomes
<script src="js/bootstrap.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
:)
Edit - 26/06/2015 - this keeps attracting interest months later so I thought it was worth an edit. I actually really like the noConflict solution offered in the comment underneath this answer and clarified by user Pretty Cool as a separate answer. As some have reported issues with the bootstrap tooltip when the scripts are swapped. I didn't experience that issue however because I downloaded jquery UI without the tooltip as I didn't need it because bootstrap. So this issue never came up for me.
Edit - 22/07/2015 - Don't confuse
jquery-ui
withjquery
! While Bootstrap's JavaScript requires jQuery to be loaded before, it doesn't rely on jQuery-UI. Sojquery-ui.js
can be loaded afterbootstrap.min.js
, whilejquery.js
always needs to be loaded before Bootstrap.
The list()
function [docs] will convert a string into a list of single-character strings.
>>> list('hello')
['h', 'e', 'l', 'l', 'o']
Even without converting them to lists, strings already behave like lists in several ways. For example, you can access individual characters (as single-character strings) using brackets:
>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'
You can also loop over the characters in the string as you can loop over the elements of a list:
>>> for c in 'hello':
... print c + c,
...
hh ee ll ll oo
You are posting the data, so it should be $_POST. But 'name' is not the best name to use.
name = "name"
will only cause confusion IMO.
Many of us develop in Eclipse via a Maven project. If so,
you can include Tomcat dependencies in Maven via the tomcat-servlet-api
and tomcat-jsp-api
jars. One exists for each version of Tomcat. Usually adding these with scope provided
to your POM is sufficient. This will keep your build more portable.
If you upgrade Tomcat in the future, you simply update the version of these jars as well.
Use the time.Now()
function and the time.Format()
method.
t := time.Now()
fmt.Println(t.Format("20060102150405"))
prints out 20110504111515
, or at least it did a few minutes ago. (I'm on Eastern Daylight Time.) There are several pre-defined time formats in the constants defined in the time package.
You can use time.Now().UTC()
if you'd rather have UTC than your local time zone.

A space in a CSS selector selects child elements.
.btn input
This is basically what you wrote and it would select <input>
elements within any element that has the btn
class.
I think you're looking for
input[disabled].btn:hover, input[disabled].btn:active, input[disabled].btn:focus
This would select <input>
elements with the disabled
attribute and the btn
class in the three different states of hover
, active
and focus
.

Update for Laravel 6
Now that Laravel 6 is released you need to install laravel/ui
.
composer require laravel/ui --dev
php artisan ui vue --auth
You can change vue
with react
if you use React in your project (see Using React).
And then you need to perform the migrations and compile the frontend
php artisan migrate
npm install && npm run dev
Source : Laravel Documentation for authentication
Want to get started fast? Install the laravel/ui Composer package and run php artisan ui vue --auth in a fresh Laravel application. After migrating your database, navigate your browser to http://your-app.test/register or any other URL that is assigned to your application. These commands will take care of scaffolding your entire authentication system!
Note: That's only if you want to use scaffolding, you can use the default User model and the Eloquent authentication driver.

I have faced this problem and I made research and didn't get anything, so I was trying and finally, I knew the cause of this problem. the problem on the API, make sure you have a good variable name I used $start_date and it caused the problem, so I try $startdate and it works!
as well make sure you send all parameter that declare on API, for example, $startdate = $_POST['startdate']; $enddate = $_POST['enddate'];
you have to pass this two variable from the retrofit.
as well if you use date on SQL statement, try to put it inside '' like '2017-07-24'
I hope it helps you.
It just doesn't make sense at all to be spending time invoking/defining routings. Even if you do need custom control, it's probably only for some of the time, and for the most bit you want to be able to just create a standard file structure of routings and have a module do it automatically.
Try Route Magic
As you scale your app, the routing invocations will start to form a giant heap of code that serves no purpose. You want to do just 2 lines of code to handle all the app.use
routing invocations with Route Magic like this:
const magic = require('express-routemagic')
magic.use(app, __dirname, '[your route directory]')
For those you want to handle manually, just don't use pass the directory to Magic.

Wikipedia never lets down:
I have found the following code to be the most consistent, performant, and simple.
var scripts = document.getElementsByTagName('script');
var thisScript = null;
var i = scripts.length;
while (i--) {
if (scripts[i].src && (scripts[i].src.indexOf('yourscript.js') !== -1)) {
thisScript = scripts[i];
break;
}
}
console.log(thisScript);
Steps to reproduce can be simplified to this:
var contextOne = new EntityContext();
var contextTwo = new EntityContext();
var user = contextOne.Users.FirstOrDefault();
var group = new Group();
group.User = user;
contextTwo.Groups.Add(group);
contextTwo.SaveChanges();
Code without error:
var context = new EntityContext();
var user = context.Users.FirstOrDefault();
var group = new Group();
group.User = user; // Be careful when you set entity properties.
// Be sure that all objects came from the same context
context.Groups.Add(group);
context.SaveChanges();
Using only one EntityContext
can solve this. Refer to other answers for other solutions.
Revised Answer
If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:
var myname varchar2(20);
exec :myname := 'Tom';
SELECT *
FROM Customers
WHERE Name = :myname;
In many tools (such as Toad and SQL Developer), omitting the var
and exec
statements will cause the program to prompt you for the value.
Original Answer
A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT
(roughly equivalent to print
) to output the variable:
DECLARE
myname varchar2(20);
BEGIN
myname := 'Tom';
dbms_output.print_line(myname);
END;
This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:
CREATE FUNCTION my_function (myname in varchar2)
my_refcursor out sys_refcursor
BEGIN
open my_refcursor for
SELECT *
FROM Customers
WHERE Name = myname;
return my_refcursor;
END my_function;
on Mac OS X (BSD find): Same as accepted answer, the .*/

Kotlin can remove findViewById and reduce code for setOnClickListener in android studio. For full reference: Kotlin awesome features
value of mutable variables can be changed at anytime, while you can not change value of immutable variables.
where should I use var and where val ?
use var where value is changing frequently. For example while getting location of android device
var integerVariable : Int? = null
use val where there is no change in value in whole class. For example you want set textview or button's text programmatically.
val stringVariables : String = "Button's Constant or final Text"
If you're running a jar file with java -jar
, the -classpath
argument is ignored. You need to set the classpath in the manifest file of your jar, like so:
Class-Path: jar1-name jar2-name directory-name/jar3-name
See the Java tutorials: Adding Classes to the JAR File's Classpath.
Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':
' after "Class-Path
" like you showed, it would not work.
I'm not entirely sure I know what you're asking about, but you can use string functions to create the actual ID that you're looking for.
var base = "common";
var num = 3;
var o = document.getElementById(base + num); // will find id="common3"
If you don't know the actual ID, then you can't look up the object with getElementById, you'd have to find it some other way (by class name, by tag type, by attribute, by parent, by child, etc...).
Now that you've finally given us some of the HTML, you could use this plain JS to find all form elements that have an ID that starts with "poll-":
// get a list of all form objects that have the right type of ID
function findPollForms() {
var list = getElementsByTagName("form");
var results = [];
for (var i = 0; i < list.length; i++) {
var id = list[i].id;
if (id && id.search(/^poll-/) != -1) {
results.push(list[i]);
}
}
return(results);
}
// return the ID of the first form object that has the right type of ID
function findFirstPollFormID() {
var list = getElementsByTagName("form");
var results = [];
for (var i = 0; i < list.length; i++) {
var id = list[i].id;
if (id && id.search(/^poll-/) != -1) {
return(id);
}
}
return(null);
}
Java 8 has introduced a new class, Optional<T>
, that can be used in such cases. To use it, you'd modify your code slightly as follows:
interface B<E>{ Optional<E> method(); }
class A implements B<Void>{
public Optional<Void> method(){
// do something
return Optional.empty();
}
}
This allows you to ensure that you always get a non-null return value from your method, even when there isn't anything to return. That's especially powerful when used in conjunction with tools that detect when null
can or can't be returned, e.g. the Eclipse @NonNull
and @Nullable
annotations.
Why don't you just write an empty method in Person and override it in the children classes? And call it, when it needs to be:
void caluculate(Person p){
p.dotheCalculate();
}
This would mean you have to have the same method in both children classes, but i don't see why this would be a problem at all.

It's important to match which version of react-navigation library you're using to the solution as they're all different. For those still using react-navigation v1.0.0 for some reason like me, both these worked:

There is a fundamental concept of IP routing: You must have a unique IP address if you want your machine to be reachable via the Internet. This is called a "Public IP Address". "www.whatismyipaddress.com" will give you this. If your server is behind some default gateway, IP packets would reach you via that router. You can not be reached via your private IP address from the outside world. You should note that private IP addresses of client and server may be same as long as their corresponding default gateways have different addresses (that's why IPv4 is still in effect) I guess you're trying to ping from your private address of your client to the public IP address of the server (provided by whatismyipaddress.com). This is not feasible. In order to achieve this, a mapping from private to public address is required, a process called Network Address Translation or NAT in short. This is configured in Firewall or Router. You can create your own private network (say via wifi). In this case, since your client and server would be on the same logical network, no private to public address translation would be required and hence you can communicate using your private IP addresses only.
This message can also occur when you specify the incorrect decryption password (yeah, lame, but not quite obvious to realize this from the error message, huh?).
I was using the command line to decrypt the recent DataBase backup for my auxiliary tool and suddenly faced this issue.
Finally, after 10 mins of grief and plus reading through this question/answers I have remembered that the password is different and everything worked just fine with the correct password.
To explain the problem, your error is as follows:
LoadError: cannot load such file -- uglifier
(in /home/cool_tech/cool_tech/app/assets/javascripts/application.js)
This means somewhere in application.js
, your app is referencing uglifier
(probably in the manifest
area at the top of the file). To fix the issue, you either need to remove the reference to uglifier
, or make sure the uglifier
file is present in your app, hence the answers you've been provided
Fix
If you've had no luck with adding the gem to your GemFile, a quick fix would be to remove any reference to uglifier
in your application.js
manifest. This, of course, will be temporary, but will at least allow you to precompile your assets
You can use this conversion table: http://roselab.jhu.edu/~raj/MISC/hexdectxt.html
eg, if you want a transparency of 60%, you use 3C (hex equivalent).
This is usefull for IE background gradient transparency:
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#3C545454, endColorstr=#3C545454);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#3C545454, endColorstr=#3C545454)";
where startColorstr and endColorstr: 2 first characters are a hex value for transparency, and the six remaining are the hex color.
Just having final
will have the intended effect.
final int x = 5;
...
x = 10; // this will cause a compilation error because x is final
Declaring static is making it a class variable, making it accessible using the class name <ClassName>.x
You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:
clean:
@if [ "test" = "test" ]; then\
echo "Hello world";\
fi
Note that the closing ";" and "\" are necessary.
TCP sockets remain open till they are closed.
That said, it's very difficult to detect a broken connection (broken, as in a router died, etc, as opposed to closed) without actually sending data, so most applications do some sort of ping/pong reaction every so often just to make sure the connection is still actually alive.
I ran into a very similar problem with my Xamarin Windows Phone 8.1 app. The reason JObject.Parse(json) would not work for me was because my Json had a beginning "[" and an ending "]". In order to make it work, I had to remove those two characters. From your example, it looks like you might have the same issue.
jsonResult = jsonResult.TrimStart(new char[] { '[' }).TrimEnd(new char[] { ']' });
I was then able to use the JObject.Parse(jsonResult) and everything worked.

The error message is confusing for one big reason:
Primitive type names are not reserved in PHP
The following are all valid class declarations:
class string { }
class int { }
class float { }
class double { }
My mistake was in thinking that the error message was referring solely to the string primitive type - the word 'instance' should have given me pause. An example to illustrate further:
class string { }
$n = 1234;
$s1 = (string)$n;
$s2 = new string();
$a = array('no', 'yes');
printf("\$s1 - primitive string? %s - string instance? %s\n",
$a[is_string($s1)], $a[is_a($s1, 'string')]);
printf("\$s2 - primitive string? %s - string instance? %s\n",
$a[is_string($s2)], $a[is_a($s2, 'string')]);
Output:
$s1 - primitive string? yes - string instance? no
$s2 - primitive string? no - string instance? yes
In PHP it's possible for a string
to be a string
except when it's actually a string
. As with any language that uses implicit type conversion, context is everything.

You can get the events from pygame and then watch out for the KEYDOWN
event, instead of looking at the keys returned by get_pressed()
(which gives you keys that are currently pressed down, whereas the KEYDOWN
event shows you which keys were pressed down on that frame).
What's happening with your code right now is that if your game is rendering at 30fps, and you hold down the left arrow key for half a second, you're updating the location 15 times.
events = pygame.event.get()
for event in events:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
location -= 1
if event.key == pygame.K_RIGHT:
location += 1
To support continuous movement while a key is being held down, you would have to establish some sort of limitation, either based on a forced maximum frame rate of the game loop or by a counter which only allows you to move every so many ticks of the loop.
move_ticker = 0
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
if move_ticker == 0:
move_ticker = 10
location -= 1
if location == -1:
location = 0
if keys[K_RIGHT]:
if move_ticker == 0:
move_ticker = 10
location+=1
if location == 5:
location = 4
Then somewhere during the game loop you would do something like this:
if move_ticker > 0:
move_ticker -= 1
This would only let you move once every 10 frames (so if you move, the ticker gets set to 10, and after 10 frames it will allow you to move again)

Sometimes SUM_IF can get the job done.
Suppose you have a sheet of product information, including unique productID
in column A and unit price in column P. And a sheet of purchase order entries with product IDs in column A, and you want column T to calculate the unit price for the entry.
The following formula will do the trick in cell Entries!T2 and can be copied to the other cells in the same column.
=SUMIF(Products!$A$2:$A$9999,Entries!$A2, Products!$P$2:$9999)
Then you could have another column with number of items per entry and multiply it with the unit price to get total cost for the entry.
So basic idea is to have a div (with display none) containing items to print. Now on click of a button do not print to entire body but just that particular div. Faced lots of issues while printing a div (part of HTML) using window.print(). Used below method and it works seamlessly in edge, chrome and Mozilla for me, let see if it help you too.

frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
frameDoc.document.open();
frameDoc.document.write("<html><head>\n\n " +

frameDoc.document.close();
setTimeout(function () {
window.frames["frame1"].focus();
window.frames["frame1"].print();

Technically, there are two issues with the code posted by BGM:
the adding of the handlers in the WaitForPageLoad method is potentially too late. The navigation is initiated before the handlers are added which means that in very rare cases where the browser already has the page it may complete before the handlers are added in which case you will miss the event and sit forever waiting.
The solution is to add the handlers before the navigation starts and remove them after the navigation completed
This means the WaitForPageLoad method needs to be split into two methods. One is called before initiating the navigation. It should set the handlers. The second part does the ReadyState monitoring and cleans up when 'Ready'.
good programming practices is to add a timeout so that a lost (or crashed, or looping) browser doesn't make your code wait forever for the document completed even
I can think of a situation where postfix is slower than prefix increment:
Imagine a processor with register A
is used as accumulator and it's the only register used in many instructions (some small microcontrollers are actually like this).
Now imagine the following program and their translation into a hypothetical assembly:
Prefix increment:
a = ++b + c;
; increment b
LD A, [&b]
INC A
ST A, [&b]
; add with c
ADD A, [&c]
; store in a
ST A, [&a]
Postfix increment:
a = b++ + c;
; load b
LD A, [&b]
; add with c
ADD A, [&c]
; store in a
ST A, [&a]
; increment b
LD A, [&b]
INC A
ST A, [&b]
Note how the value of b
was forced to be reloaded. With prefix increment, the compiler can just increment the value and go ahead with using it, possibly avoid reloading it since the desired value is already in the register after the increment. However, with postfix increment, the compiler has to deal with two values, one the old and one the incremented value which as I show above results in one more memory access.
Of course, if the value of the increment is not used, such as a single i++;
statement, the compiler can (and does) simply generate an increment instruction regardless of postfix or prefix usage.
As a side note, I'd like to mention that an expression in which there is a b++
cannot simply be converted to one with ++b
without any additional effort (for example by adding a - 1
). So comparing the two if they are part of some expression is not really valid. Often, where you use b++
inside an expression you cannot use ++b
, so even if ++b
were potentially more efficient, it would simply be wrong. Exception is of course if the expression is begging for it (for example a = b++ + 1;
which can be changed to a = ++b;
).
I used the same manner of saving and retrieving a String but here with arrayList I've used HashSet as a mediator
To save arrayList to SharedPreferences we use HashSet:
1- we create SharedPreferences variable (in place where the change happens to the array)
2 - we convert the arrayList to HashSet
3 - then we put the stringSet and apply
4 - you getStringSet within HashSet and recreate ArrayList to set the HashSet.
public class MainActivity extends AppCompatActivity {
ArrayList<String> arrayList = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences prefs = this.getSharedPreferences("com.example.nec.myapplication", Context.MODE_PRIVATE);
HashSet<String> set = new HashSet(arrayList);
prefs.edit().putStringSet("names", set).apply();
set = (HashSet<String>) prefs.getStringSet("names", null);
arrayList = new ArrayList(set);
Log.i("array list", arrayList.toString());
}
}
Simply,
SELECT TIME(column_name), DATE(column_name)
See explanation here.
The Callable interface is similar to Runnable, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception.
I am Write this code in xml file ...
<Button
android:id="@+id/btn_register"
android:layout_margin="1dp"
android:layout_marginLeft="3dp"
android:layout_marginTop="10dp"
android:layout_weight="2"
android:onClick="register"
android:text="Register"
android:textColor="#000000"/>
And write this code in fragment...
public void register(View view) {
}
Edit: OP (or an editor) silently changed some of the single quotes in the original question to double quotes at some point after I provided this answer.
Your code will result in compiler errors. Your first code fragment:
char buf[10] ; buf = ''
is doubly illegal. First, in C, there is no such thing as an empty char
. You can use double quotes to designate an empty string, as with:
char* buf = "";
That will give you a pointer to a NUL
string, i.e., a single-character string with only the NUL
character in it. But you cannot use single quotes with nothing inside them--that is undefined. If you need to designate the NUL
character, you have to specify it:
char buf = '\0';
The backslash is necessary to disambiguate from character '0'
.
char buf = 0;
accomplishes the same thing, but the former is a tad less ambiguous to read, I think.
Secondly, you cannot initialize arrays after they have been defined.
char buf[10];
declares and defines the array. The array identifier buf
is now an address in memory, and you cannot change where buf
points through assignment. So
buf = // anything on RHS
is illegal. Your second and third code fragments are illegal for this reason.
To initialize an array, you have to do it at the time of definition:
char buf [10] = ' ';
will give you a 10-character array with the first char being the space '\040'
and the rest being NUL
, i.e., '\0'
. When an array is declared and defined with an initializer, the array elements (if any) past the ones with specified initial values are automatically padded with 0
. There will not be any "random content".
If you declare and define the array but don't initialize it, as in the following:
char buf [10];
you will have random content in all the elements.
for(n in 1:5) {
if(n==3) next # skip 3rd iteration and go to next iteration
cat(n)
}
There is another way, take this as example
Dim sr As String
sr = "6:10"
Rows(sr).Select
All you need to do is to convert your variables iStartRow
, iEndRow
to a string.
To find the maximum y
value of the objects in array
:
Math.max.apply(Math, array.map(function(o) { return o.y; }))

Yes, you can do the same in Seaborn directly. This is done with tsplot() which allows either a single array as input, or two arrays where the other is 'time' i.e. x-axis.
import seaborn as sns
data = [1,5,3,2,6] * 20
time = range(100)
sns.tsplot(data, time)
Probably invalid syntax in your onChange event, I avoid using like this (within the html) as I think it is messy and it is hard enough keeping JavaScript tidy at the best of times.
I would rather register the event on the document ready event in javascript. You will also definitely want to use keyup event too if you want the validation as the user is typing:
$(document).ready(function () {
$("#txtConfirmPassword").keyup(checkPasswordMatch);
});
Personally I would prefer to do the check when either password field changes, that way if they re-type the original password then you still get the same validation check:
$(document).ready(function () {
$("#txtNewPassword, #txtConfirmPassword").keyup(checkPasswordMatch);
});
Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.
In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.
The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.
To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.
Why?
It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.
See the following information in MSDN about the GAC changes in 4.0.
For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application
The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.
As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.
.load()
& .unload()
have been deprecated$(window).load();
Will execute after the page along with all its contents are done loading. This means that all images, CSS (and content defined by CSS like custom fonts and images), scripts, etc. are all loaded. This happens event fires when your browser's "Stop" -icon becomes gray, so to speak. This is very useful to detect when the document along with all its contents are loaded.
$(document).ready();
This on the other hand will fire as soon as the web browser is capable of running your JavaScript, which happens after the parser is done with the DOM. This is useful if you want to execute JavaScript as soon as possible.
$(window).unload();
This event will be fired when you are navigating off the page. That could be Refresh/F5, pressing the previous page button, navigating to another website or closing the entire tab/window.
To sum up, ready() will be fired before load(), and unload() will be the last to be fired.
Utilize the <a>
tag.
At the top of your website, put an anchor with specified name.
<a name="top"></a>
Then your "back to top" link points to it.
<a href="#top">back to top</a>
I just found out that it works if you add an empty listener, don't ask me why, but I tested it on iPhone and iPad with iOS 9.3.2 and it worked fine.
if(/iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream){
var elements = document.getElementsByTagName('a');
for(var i = 0; i < elements.length; i++){
elements[i].addEventListener('touchend',function(){});
}
}
It is not an import problem. You simply call .dropDuplicates()
on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...)
is pyspark.sql.dataframe.DataFrame
, after you apply .collect()
it is a plain Python list
, and lists don't provide dropDuplicates
method. What you want is something like this:
(df1 = sqlContext
.createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
.dropDuplicates())
df1.collect()
You need to change the import of your class:
import org.apache.commons.codec.binary.Base64;
And then change your class to use the Base64 class.
Here's some example code:
byte[] encodedBytes = Base64.encodeBase64("Test".getBytes());
System.out.println("encodedBytes " + new String(encodedBytes));
byte[] decodedBytes = Base64.decodeBase64(encodedBytes);
System.out.println("decodedBytes " + new String(decodedBytes));
Then read why you shouldn't use sun.* packages.
You can now use java.util.Base64
with Java 8. First, import it as you normally do:
import java.util.Base64;
Then use the Base64 static methods as follows:
byte[] encodedBytes = Base64.getEncoder().encode("Test".getBytes());
System.out.println("encodedBytes " + new String(encodedBytes));
byte[] decodedBytes = Base64.getDecoder().decode(encodedBytes);
System.out.println("decodedBytes " + new String(decodedBytes));
If you directly want to encode string and get the result as encoded string, you can use this:
String encodeBytes = Base64.getEncoder().encodeToString((userName + ":" + password).getBytes());
See Java documentation for Base64 for more.
I was having this issue as well and the problem was in the view controllers. I'm not sure how your application is structured, so I'll just explain what I found. I'm pretty new to xcode and coding, so bear with me.
I was trying to programmatically change the text on a UILabel. Using "self.mylabel.text" worked fine until I added another view controller under the same class that didn't also include that label. That is when I got the error that you're seeing. When I added the same UILabel and connected it into that additional view controller, the error went away.
In short, it seems that in Swift, all view controllers assigned to the same class have to reference the code you have in there, or else you get an error. If you have two different view controllers with different code, assign them to different classes. This worked for me and hopefully applies to what you're doing.
By default, Java's int and long math silently wrap around on overflow and underflow. (Integer operations on other integer types are performed by first promoting the operands to int or long, per JLS 4.2.2.)
As of Java 8, java.lang.Math
provides addExact
, subtractExact
, multiplyExact
, incrementExact
, decrementExact
and negateExact
static methods for both int and long arguments that perform the named operation, throwing ArithmeticException on overflow. (There's no divideExact method -- you'll have to check the one special case (MIN_VALUE / -1
) yourself.)
As of Java 8, java.lang.Math also provides toIntExact
to cast a long to an int, throwing ArithmeticException if the long's value does not fit in an int. This can be useful for e.g. computing the sum of ints using unchecked long math, then using toIntExact
to cast to int at the end (but be careful not to let your sum overflow).
If you're still using an older version of Java, Google Guava provides IntMath and LongMath static methods for checked addition, subtraction, multiplication and exponentiation (throwing on overflow). These classes also provide methods to compute factorials and binomial coefficients that return MAX_VALUE
on overflow (which is less convenient to check). Guava's primitive utility classes, SignedBytes
, UnsignedBytes
, Shorts
and Ints
, provide checkedCast
methods for narrowing larger types (throwing IllegalArgumentException on under/overflow, not ArithmeticException), as well as saturatingCast
methods that return MIN_VALUE
or MAX_VALUE
on overflow.

You could try this:
#include <stdio.h>
int main()
{
int i,j;
int my_array[3][3] ={10, 23, 42, 1, 654, 0, 40652, 22, 0};
for(i = 0; i < 3; i++)
{
for(j = 0; j < 3; j++)
{
printf("%d ", my_array[i][j]);
}
printf("\n");
}
return 0;
}
binascii methodes are easier by the way
>>> import binascii
>>> x=b'test'
>>> x=binascii.hexlify(x)
>>> x
b'74657374'
>>> y=str(x,'ascii')
>>> y
'74657374'
>>> x=binascii.unhexlify(x)
>>> x
b'test'
>>> y=str(x,'ascii')
>>> y
'test'
Hope it helps. :)
In SQL Server 2012 and later, there is the FORMAT()
function. You can pass it a 'P'
parameter for percentage. For example:
SELECT FORMAT((37.0/38.0),'P') as [Percentage] -- 97.37 %
To support percentage decimal precision, you can use P0
for no decimals (whole-numbers) or P3
for 3 decimals (97.368%).
SELECT FORMAT((37.0/38.0),'P0') as [WholeNumberPercentage] -- 97 %
SELECT FORMAT((37.0/38.0),'P3') as [ThreeDecimalsPercentage] -- 97.368 %
On Android 4.4.4, it seems the only way I could stop an alpha fading animation on a View was calling View.animate().cancel()
(i.e., calling .cancel()
on the View's ViewPropertyAnimator
).
Here's the code I'm using for compatibility before and after ICS:
public void stopAnimation(View v) {
v.clearAnimation();
if (canCancelAnimation()) {
v.animate().cancel();
}
}
... with the method:
/**
* Returns true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
* @return true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
*/
public static boolean canCancelAnimation() {
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}
Here's the animation that I'm stopping:
v.setAlpha(0f);
v.setVisibility(View.VISIBLE);
// Animate the content view to 100% opacity, and clear any animation listener set on the view.
v.animate()
.alpha(1f)
.setDuration(animationDuration)
.setListener(null);
Approach 1: You can inject ApplicationContext by implementing ApplicationContextAware interface. Reference link.
@Component
public class ApplicationContextProvider implements ApplicationContextAware {
private ApplicationContext applicationContext;
public ApplicationContext getApplicationContext() {
return applicationContext;
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
}
Approach 2: Autowire Application context in any of spring managed beans.
@Component
public class SpringBean {
@Autowired
private ApplicationContext appContext;
}
Reference link.
The main difference is that a 8-bit PNG comprises a max. of 256 colours, like GIFs. PNG-24 is a lossless format and can contain up to 16 million colours.

functools.reduce and pd.concat are good solutions but in term of execution time pd.concat is the best.
from functools import reduce
import pandas as pd
dfs = [df1, df2, df3, ...]
nan_value = 0
# solution 1 (fast)
result_1 = pd.concat(dfs, join='outer', axis=1).fillna(nan_value)
# solution 2
result_2 = reduce(lambda df_left,df_right: pd.merge(df_left, df_right,
left_index=True, right_index=True,
how='outer'),
dfs).fillna(nan_value)
For me it was an old version of npm
.
Run npm install npm@latest -g

Please try using on-tap instead of ng-click event. I had this issue. I resolved it by making my clear-search-box button inside search form label and replaced ng-click of clear-button by on-tap. It works fine now.
In my case it was not enough to add these lines :
var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));
I tried adding the parameterLimit option on urlencoded function as the documentation says and error no longer appears.
The parameterLimit option controls the maximum number of parameters that are allowed in the URL-encoded data. If a request contains more parameters than this value, a 413 will be returned to the client. Defaults to 1000.
Try with this code:
var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));
Using groupby
you could split into two dataframes like
In [1047]: df1, df2 = [x for _, x in df.groupby(df['Sales'] < 30)]
In [1048]: df1
Out[1048]:
A Sales
2 7 30
3 6 40
4 1 50
In [1049]: df2
Out[1049]:
A Sales
0 3 10
1 4 20
I think this may help:
$('mycheckbox')[0].checked
Secondly, you need to be aware that the checked attribute RETURNS a string "true", "false"
Why is this important? Because you need to use the correct Type. A string, not a boolean. This also important when parsing your checkbox.
$('mycheckbox')[0].checked = "true"
if($('mycheckbox')[0].checked === "true"){
//do something
}
You also need to realize that the "checked" ATTRIBUTE is for setting the value of the checkbox initially. This doesn't do much once the element is rendered to the DOM. Picture this working when the webpage loads and is initially parsed.
I'll go with IE's preference on this one: <input type="checkbox" checked="checked"/>
Lastly, the main aspect of confusion for a checkbox is that the checkbox UI element is not the same as the element's property value. They do not correlate directly.
If you work in .net, you'll discover that the user "checking" a checkbox never reflects the actual bool value passed to the controller.
To set the UI, I use both $('mycheckbox').val(true);
and $('mycheckbox').attr('checked', 'checked');
<input type="checkbox" checked="checked">
$('mycheckbox')[0].checked = "true";
$('mycheckbox').val(true);
and $('mycheckbox').attr('checked', 'checked');
in your servlet
request.setAttribute("submitDone","done");
return mapping.findForward("success");
In your jsp
<c:if test="${not empty submitDone}">
<script>alert("Form submitted");
</script></c:if>
Handling CORS requests properly is a tad more involved. Here is a function that will respond more fully (and properly).
/**
* An example CORS-compliant method. It will allow any GET, POST, or OPTIONS requests from any
* origin.
*
* In a production environment, you probably want to be more restrictive, but this gives you
* the general idea of what is involved. For the nitty-gritty low-down, read:
*
* - https://developer.mozilla.org/en/HTTP_access_control
* - https://fetch.spec.whatwg.org/#http-cors-protocol
*
*/
function cors() {
// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
// Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
// you want to allow, and if so:
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
// may also be using PUT, PATCH, HEAD etc
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}
echo "You have CORS!";
}
When a browser wants to execute a cross-site request it first confirms that this is okay with a "pre-flight" request to the URL. By allowing CORS you are telling the browser that responses from this URL can be shared with other domains.
CORS does not protect your server. CORS attempts to protect your users by telling browsers what the restrictions should be on sharing responses with other domains. Normally this kind of sharing is utterly forbidden, so CORS is a way to poke a hole in the browser's normal security policy. These holes should be as small as possible, so always check the HTTP_ORIGIN against some kind of internal list.
There are some dangers here, especially if the data the URL serves up is normally protected. You are effectively allowing browser content that originated on some other server to read (and possibly manipulate) data on your server.
If you are going to use CORS, please read the protocol carefully (it is quite small) and try to understand what you're doing. A reference URL is given in the code sample for that purpose.
It has been observed that the HTTP_ORIGIN header is insecure, and that is true. In fact, all HTTP headers are insecure to varying meanings of the term. Unless a header includes a verifiable signature/hmac, or the whole conversation is authenticated via TLS, headers are just "something the browser has told me".
In this case, the browser is saying "an object from domain X wants to get a response from this URL. Is that okay?" The point of CORS is to be able to answer, "yes I'll allow that".
Create a new style
<!-- Theme.AppCompat.Light.Dialog -->
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">

The parent theme is the key here. Choose your colorAccent
DatePickerDialog = new DatePickerDialog(context,R.style.DialogTheme,this,now.get(Calendar.YEAR),now.get(Calendar.MONTH),now.get(Calendar.DAY_OF_MONTH);
Result:
Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).

This thing is empty nested list from which ne will append data to empty dict
ls = [['a','a1','a2','a3'],['b','b1','b2','b3'],['c','c1','c2','c3'],
['d','d1','d2','d3']]
this means to create four empty dict inside data_dict
data_dict = {f'dict{i}':{} for i in range(4)}
for i in range(4):
upd_dict = {'val' : ls[i][0], 'val1' : ls[i][1],'val2' : ls[i][2],'val3' : ls[i][3]}
data_dict[f'dict{i}'].update(upd_dict)
print(data_dict)
The output
{'dict0': {'val': 'a', 'val1': 'a1', 'val2': 'a2', 'val3': 'a3'}, 'dict1': {'val': 'b', 'val1': 'b1', 'val2': 'b2', 'val3': 'b3'},'dict2': {'val': 'c', 'val1': 'c1', 'val2': 'c2', 'val3': 'c3'}, 'dict3': {'val': 'd', 'val1': 'd1', 'val2': 'd2', 'val3': 'd3'}}

To answer one of the questions, it is necessary to have both a global and local install for the tools to work.
If you try to run ng serve
on an application without the local install of the CLI (global install only), you will get the following error.
You have to be inside an Angular CLI project in order to use the serve command.
It will also print this message:
Please take the following steps to avoid issues:
"npm install --save-dev @angular/cli@latest"
Run that npm
command to update the CLI locally, and avoid the warning that you are getting.
Other question: It looks like they do not have to be in sync, but it's probably best that they are in order to avoid any unusual behavior with the tool, or any inconsistencies with the code the tool generates.
Why do we need both the global install, and a local install?
The global install is needed to start a new application. The ng new <app-name>
command is run using the global installation of the CLI. In fact, if you try to run ng new
while inside the folder structure of an existing CLI application, you get this lovely error:
You cannot use the
new
command inside an Angular CLI project.
Other commands that can be run from the global install are ng help
, ng get/set
with the --global
option, ng version
, ng doc
, and ng completion
.
The local install of the CLI is used after an application has been built. This way, when new versions of the CLI are available, you can update your global install, and not affect the local install. This is good for the stability of a project. Most ng
commands only make sense with the local version, like lint
, build
and serve
, etc.
According to the CLI GitHub readme, to update the CLI you must update the global and local package. However, I have used the CLI where the global and local version vary without any trouble so far. If I ever run across an error related to having the global and local CLI versions out of sync, I will post that here.
The answer is that you have to use TableRow.LayoutParams, not LinearLayout.LayoutParams or any other LayoutParams.
TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);
The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen. The text view's parent is a table row, hence:
http://developer.android.com/reference/android/widget/TableRow.LayoutParams.html
It means:
'O' (Python) objects
The first character specifies the kind of data and the remaining characters specify the number of bytes per item, except for Unicode, where it is interpreted as the number of characters. The item size must correspond to an existing type, or an error will be raised. The supported kinds are to an existing type, or an error will be raised. The supported kinds are:
'b' boolean
'i' (signed) integer
'u' unsigned integer
'f' floating-point
'c' complex-floating point
'O' (Python) objects
'S', 'a' (byte-)string
'U' Unicode
'V' raw data (void)
Another answer helps if need check type
s.
If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:
Example:
<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
<input type="hidden" name="packing_slip" value="35592" />
<input type="hidden" name="reference" value="0018439" />
<input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>
Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.
Use build job plugin for that task in order to trigger other jobs from jenkins file. You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs. I gave some easy-to-read cookbook example for that.
1.example for triggering external job from jenkins file with conditional example:
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueOfParam2')
]
}
2.example triggering multiple jobs from jenkins file with conditionals example:
def jobs =[
'job1Title'{
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueNameOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueNameOfParam2')
]
}
},
'job2Title'{
if (env.GIT_COMMIT == 'someCommitHashToPerformAdditionalTest') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam3',value: 'valueOfParam3')
booleanParam(name: 'keyNameOfParam4',value:'valueNameOfParam4')
booleanParam(name: 'keyNameOfParam5',value:'valueNameOfParam5')
]
}
}
You can start your container with the flag -P
. This "assigns" a random port to the exposed port of your image.
With docker port <container id>
you can see the randomly choosen port. Access is then possible via localhost:port
.
So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.
protected void onCreate(Bundle savedInstanceState) { setContentView(R.layout.my_layout); Bitmap bitmap = getIntent().getParcelableExtra("image"); ImageView imageView = (ImageView) findViewById(R.id.imageview); imageView.setImageBitmap(bitmap); }
I think you can use the nrows
parameter. From the docs:
nrows : int, default None
Number of rows of file to read. Useful for reading pieces of large files
which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):
In [1]: import pandas as pd
In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
In [3]: len(z)
Out[3]: 20
In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s
By the way, I've just found out this post: http://blogs.msdn.com/b/webtopics/archive/2010/03/19/iis-7-5-how-to-enable-iis-configuration-auditing.aspx it explains how to audit changes on IIS. For those who face similar problems I suggest to turn on auditing and later see why your site stopped working.
Use log4j or JDK logging so you can just create a static logger in the class and call it like this:
LOG.info("foo")
You can use java split function to split the filename from the extension, if you are sure there is only one dot in the filename which for extension.
File filename = new File('test.txt');
File.getName().split("[.]");
so the split[0]
will return "test" and split[1] will return "txt"
C style, simple ring buffer for integers. First use init than use put and get. If buffer does not contain any data it returns "0" zero.

The .btn-lg
class has the following CSS in Bootstrap 3 (link):
.btn-lg {
padding: 10px 16px;
font-size: 18px;
line-height: 1.33;
border-radius: 6px;
}
If you apply the same font-size
and line-height
to your span (either .glyphicon-link
or a newly created .glyphicons-lg
if you're going to use this effect in more than one instance), you'll get a Glyphicon the same size as the large button.
Django employs a slightly modified kind of MVC. There's no concept of a "controller" in Django. The closest proxy is a "view", which tends to cause confusion with MVC converts because in MVC a view is more like Django's "template".
In Django, a "model" is not merely a database abstraction. In some respects, it shares duty with the Django's "view" as the controller of MVC. It holds the entirety of behavior associated with an instance. If that instance needs to interact with an external API as part of it's behavior, then that's still model code. In fact, models aren't required to interact with the database at all, so you could conceivable have models that entirely exist as an interactive layer to an external API. It's a much more free concept of a "model".
You need a fast way to convert a []string to []byte type. To use in situations such as storing text data into a random access file or other type of data manipulation that requires the input data to be in []byte type.
package main
func main() {
var s string
//...
b := []byte(s)
//...
}
which is useful when using ioutil.WriteFile, which accepts a bytes slice as its data parameter:
WriteFile func(filename string, data []byte, perm os.FileMode) error
Another example
package main
import (
"fmt"
"strings"
)
func main() {
stringSlice := []string{"hello", "world"}
stringByte := strings.Join(stringSlice, " ")
// Byte array value
fmt.Println([]byte(stringByte))
// Corresponding string value
fmt.Println(string([]byte(stringByte)))
}
Output:
[104 101 108 108 111 32 119 111 114 108 100] hello world

You need to explicitly enable the home action if running on ICS. From the docs:
Note: If you're using the icon to navigate to the home activity, beware that beginning with Android 4.0 (API level 14), you must explicitly enable the icon as an action item by calling setHomeButtonEnabled(true) (in previous versions, the icon was enabled as an action item by default).
As per latest standards, this is how it should be done.

The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:
SQLSVCACCOUNT: NT AUTHORITY\SYSTEM
According to the link provided by @royki:
The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.
This would explain why other respondents had success after changing to different accounts:
To fix the user profile that's causing the error, follow the steps listed KB947215.
The main steps from KB947215 are summarized as follows:-
regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
Navigate to the SID for the corrupted profile
To find the SID, click on each SID GUID, review the value for the ProfileImagePath
value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:
The main system account SIDs of interest are:
SID Name Also Known As
S-1-5-18 Local System NT AUTHORITY\SYSTEM
S-1-5-19 LocalService NT AUTHORITY\LOCAL SERVICE
S-1-5-20 NetworkService NT AUTHORITY\NETWORK SERVICE
For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

.grep -r -e string directory
-r
is for recursive; -e
is optional but its argument specifies the regex to search for. Interestingly, POSIX grep
is not required to support -r
(or -R
), but I'm practically certain that System V in practice they (almost) all do. Some versions of grep
did, sogrep
support -R
as well as (or conceivably instead of) -r
; AFAICT, it means the same thing.
The simplest solution is to follow the installation instruction from pip's home site.
Basically, this consists in:
sudo python get-pip.py
The main advantage of that solution is that it install pip for the python version that has been used to run get-pip.py
, which means that if you use the default OS X installation of python to run get-pip.py
you will install pip for the python install from the system.
Most solutions that use a package manager (homebrew or macport) on OS X create a redundant installation of python in the environment of the package manager which can create inconsistencies in your system since, depending on what you are doing, you may call one installation of python instead of another.
Very much a porcelain command, not good if you want this for scripting:
git branch -vv # doubly verbose!
Note that with git 1.8.3, that upstream branch is displayed in blue (see "What is this branch tracking (if anything) in git?")
If you want clean output, see arcresu's answer - it uses a porcelain command that I don't believe existed at the time I originally wrote this answer, so it's a bit more concise and works with branches configured for rebase, not just merge.
I came up with this method because while on the CLI, it's not possible to use the methods provided in the other answers here and it had always bugged me.
Basic Example
FOR /L %L IN (0,0,1) DO @(
ECHO. Counter always 0, See "%L" = "0" - Waiting a split second&ping -n 1 127.0.0.1>NUL )
This is truly an infinite loop!
This is useful for monitoring something in a CMD
window, and allows you to use CTRL
+C
to break it when you're done.
Want to Have a counter?
Either use SET /A
OR You can modify the FOR /L
Loop to do the counting and still be infinite (Note, BOTH of these methods have a 32bit integer overflow)
SET /A
Method:
FOR /L %L IN (0,0,1) DO @(
SET /A "#+=1"&ECHO. L Still equals 0, See "%L = 0"! - Waiting a split second &ping -n 1 127.0.0.1>NUL )
Native FOR /L
Counter:
FOR /L %L IN (-2147483648,1,2147483648) DO @(
ECHO.Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL )
Counting Sets of 4294967295 and Showing Current Value of L:
FOR /L %L IN (1,1,2147483648) DO @(
(
IF %L EQU 0 SET /A "#+=1">NUL
)&SET /A "#+=0"&ECHO. Sets of 4294967295 - Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL )
However, what if:
For this, I determined how to use a couple methods to break the FOR
Loop prematurely effectively turning it into a "DO WHILE
" or "DO UNTIL
" Loop, which is otherwise sorely lacking in CMD.
NOTE: Most of the time a loop will continue to iterate past the condition you checked for, often this is a wanted behavior, but not in our case.
DO WHILE
" / "DO UNTIL
" LoopUPDATE: Due to wanting to use this code in CMD Scripts (and have them persist!) as well as CLI, and on thinking if there might be a "more Correct" method to achieve this I recommend using the New method!
New Method (Can be used inside CMD Scripts without exiting the script):
FOR /F %%A IN ('
CMD /C "FOR /L %%L IN (0,1,2147483648) DO @( ECHO.%%L & IF /I %%L EQU 10 ( exit /b ) )"
') DO @(
ECHO %%~A
)
At CLI:
FOR /F %A IN ('
CMD /C "FOR /L %L IN (0,1,2147483648) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b ) )"
') DO @(
ECHO %~A
)
Original Method (Will work on CLI just fine, but will kill a script.)
FOR /L %L IN (0,1,2147483648) DO @(
ECHO.Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL&(
IF /I %L EQU 10 (
ECHO.Breaking the Loop! Because We have matched the condition!&DIR >&0
)
)
) 2>NUL
Through chance I had hit upon some ways to exit loops prematurely that did not close the CMD prompt when trying to do other things which gave me this Idea.
While ECHO.>&3 >NUL
had worked for me in some scenarios, I have played with this off and on over the years and found that DIR >&0 >NUL
was much more consistent.
I am re-writing this answer from here forward to use that method instead as I recently found the old note to myself to use this method instead.
DIR >&0 >NUL
The >NUL is optional, I just prefer not to have it output the error.
I prefer to match inLine when possible, as you can see in this sanitized example of a Command I use to monitor LUN Migrations on our VNX.
for /l %L IN (0,0,1) DO @(
ECHO.& ECHO.===========================================& (
[VNX CMD] | FINDSTR /R /C:"Source LU Name" /C:"State:" /C:"Time " || DIR >&0 >NUL
) & Ping -n 10 1.1.1.1 -w 1000>NUL )
Also, I have another method I found in that note to myself which I just re-tested to confirm works just as well at the CLI as the other method.
Apparently, when I first posted here I posted an older iteration I was playing with instead of the two newer ones which work better:
In this method, we use EXIT /B
to exit the For Loop, but we don't want to exit the CLI so we wrap it in a CMD session:
FOR /F %A IN ('CMD /C "FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b ) )" ') DO @(ECHO %~A)
Because the loop itself happens in the CMD session, we can use EXIT /B to exit the iteration of the loop without losing our CMD Session, and without waiting for the loop to complete, much the same as with the other method.
I would go so far as to say that this method is likely the "intended" method for the sort of scenario where you want to break a for loop at the CLI, as using CMD session is also the only way to get Delayed expansion working at the CLI for your loops, and the behavior and such behavior is clearly an intended workflow to leave a CMD session.
IE: Microsoft clearly made an intentional effort to have CMD Exit /B For loops behave this way, while the "Intended" way of doing this, as my other method, relies on having accidentally created just the right error to kick you out of the loop without letting the loop finish processing, which I only happenstantially discovered, and seems to only reliably work when using the DIR command which is fairly strange.
So that said, I think it's probably a better practice to use Method 2:
FOR /F %A IN ('CMD /C "FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b ) )" ') DO @(ECHO %~A)
Although I suspect Method 1 is going to be slightly faster:
FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( DIR >&) >NUL ) )
And in either case, both should allow DO-While loops as you need for your purposes.
you can use super while extending Exception
if (pass.length() < minPassLength)
throw new InvalidPassException("The password provided is too short");
} catch (NullPointerException e) {
throw new InvalidPassException("No password provided", e);
}
// A custom business exception
class InvalidPassException extends Exception {
InvalidPassException() {
}
InvalidPassException(String message) {
super(message);
}
InvalidPassException(String message, Throwable cause) {
super(message, cause);
}
}
}
You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document
If there is no selection, you can use the properties .selectionStart
or .selectionEnd
(with no selection they're equal).
var cursorPosition = $('#myTextarea').prop("selectionStart");
Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.
I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.
As @Ebin Joy said, If your gradle file get corrupted then there is one simple solution for that. Manually give the proxy details like shown in image. then you're good to go. This solution only works if you using any closed networks like office network etc.
CentOS is Linux, so as in just about all other Unix/Linux systems, you have the find
command. To search for files within the current directory:
find -name "filename"
You can also have wildcards inside the quotes, and not just a strict filename. You can also explicitly specify a directory to start searching from as the first argument to find:
find / -name "filename"
will look for "filename" or all the files that match the regex expression in between the quotes, starting from the root directory. You can also use single quotes instead of double quotes, but in most cases you don't need either one, so the above commands will work without any quotes as well. Also, for example, if you're searching for java files and you know they are somewhere in your /home/username, do:
find /home/username -name *.java
There are many more options to the find command and you should do a:
man find
to learn more about it.
One more thing: if you start searching from / and are not root or are not sudo running the command, you might get warnings that you don't have permission to read certain directories. To ignore/remove those, do:
find / -name 'filename' 2>/dev/null
That just redirects the stderr to /dev/null.
For Windows, you have the problem of how to strip the executable from the result of GetModuleFileName()
. The Windows API call PathRemoveFileSpec()
that Nate used for that purpose in his answer changed between Windows 8 and its predecessors. So how to remain compatible with both and safe? Luckily, there's C++17 (or Boost, if you're using an older compiler). I do this:
#include <windows.h>
#include <string>
#include <filesystem>
namespace fs = std::experimental::filesystem;
// We could use fs::path as return type, but if you're not aware of
// std::experimental::filesystem, you probably handle filenames
// as strings anyway in the remainder of your code. I'm on Japanese
// Windows, so wide chars are a must.
std::wstring getDirectoryWithCurrentExecutable()
{
int size = 256;
std::vector<wchar_t> charBuffer;
// Let's be safe, and find the right buffer size programmatically.
do {
size *= 2;
charBuffer.resize(size);
// Resize until filename fits. GetModuleFileNameW returns the
// number of characters written to the buffer, so if the
// return value is smaller than the size of the buffer, it was
// large enough.
} while (GetModuleFileNameW(NULL, charBuffer.data(), size) == size);
// Typically: c:/program files (x86)/something/foo/bar/exe/files/win64/baz.exe
// (Note that windows supports forward and backward slashes as path
// separators, so you have to be careful when searching through a path
// manually.)
// Let's extract the interesting part:
fs::path path(charBuffer.data()); // Contains the full path including .exe
return path.remove_filename() // Extract the directory ...
.w_str(); // ... and convert to a string.
}
docker-compose up --build
OR
docker-compose build --no-cache
Try this:
String output = response.getEntity(String.class);
EDIT
Thanks to @Martin Spamer to mention that it will work for Jersey 1.x jars only. For Jersey 2.x use
String output = response.readEntity(String.class);
Doing password checks on client side is unsafe especially when the password is hard coded.
The safest way is password checking on server side, but even then the password should not be transmitted plain text.
Checking the password client side is possible in a "secure way":
Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).
^\d{1,2}[\W_]?po$
\d
defines a number and {1,2}
means 1 or two of the expression before, \W
defines a non word character.

I had this problem on Mac OS X. We don't have a /proc
virtual file system, so the accepted solution cannot work.
We do, instead, have a F_GETPATH
command for fcntl
:
F_GETPATH Get the path of the file descriptor Fildes. The argu-
ment must be a buffer of size MAXPATHLEN or greater.
So to get the file associated to a file descriptor, you can use this snippet:
#include <sys/syslimits.h>
#include <fcntl.h>
char filePath[PATH_MAX];
if (fcntl(fd, F_GETPATH, filePath) != -1)
{
// do something with the file path
}
Since I never remember where MAXPATHLEN
is defined, I thought PATH_MAX
from syslimits would be fine.
Here is a solution that will automatically convert to tabs whenever you open a file.
Create this file: .../Packages/User/on_file_load.py
:
import sublime
import sublime_plugin
class OnFileLoadEventListener(sublime_plugin.EventListener):
def on_load_async(self, view):
view.run_command("unexpand_tabs")
NOTE. It causes the file to be in an unsaved state after opening it, even if no actual space-to-tab conversion took place... maybe some can help with a fix for that...

The trick is that you set the ImageView
to fill the screen but it has to be above the other layouts. This way you achieve everything you need.
If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.
on button click write this
Intent in = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
in.putExtra("crop", "true");
in.putExtra("outputX", 100);
in.putExtra("outputY", 100);
in.putExtra("scale", true);
in.putExtra("return-data", true);
startActivityForResult(in, 1);
then do this in your activity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
Bitmap bmp = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(bmp);
btnadd.requestFocus();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
bytarray.length);
}
}
According to MSDN:
By initializing strings with the
Empty
value instead ofnull
, you can reduce the chances of aNullReferenceException
occurring.
Always using IsNullOrEmpty()
is good practice nevertheless.
I was having a similar problem. I was not using the ACL stuff, so I didn't need s3:PutObjectAcl
.
In my case, I was doing (in Serverless Framework YML):
- Effect: Allow
Action:
- s3:PutObject
Resource: "arn:aws:s3:::MyBucketName"
Instead of:
- Effect: Allow
Action:
- s3:PutObject
Resource: "arn:aws:s3:::MyBucketName/*"
Which adds a /*
to the end of the bucket ARN.
Hope this helps.
I alse had the same error. Finally, I found that I have some error on my code. I use load balance for two nodejs server, but I just update the code of one server.
I change my mongod server from standalone to replication
, but I forget to do the corresponding update for the connection string, so I met this error.
standalone connection string:
mongodb://server-1:27017/mydb
replication connection string:
mongodb://server-1:27017,server-2:27017,server-3:27017/mydb?replicaSet=myReplSet
details here:[mongo doc for connection string]
I open one old Asp.net webform (.Net Framework4.5)solution with Visual Studio 2019, has same issue. The solution quite simple, go to web project's properties-> Web-> checked "Override application root URL" -> assign another port number. Save the solution and run in debug mode again. Problem resolved.
Go to the Jenkins installation, open the cmd and run:
To stop:
jenkins.exe stop
To start:
jenkins.exe start
To restart:
jenkins.exe restart
In addition to other answers about handling null
values, Convert.ToString
tries to use IFormattable
and IConvertible
interfaces before calling base Object.ToString
.
Example:
class FormattableType : IFormattable
{
private double value = 0.42;
public string ToString(string format, IFormatProvider formatProvider)
{
if (formatProvider == null)
{
// ... using some IOC-containers
// ... or using CultureInfo.CurrentCulture / Thread.CurrentThread.CurrentCulture
formatProvider = CultureInfo.InvariantCulture;
}
// ... doing things with format
return value.ToString(formatProvider);
}
public override string ToString()
{
return value.ToString();
}
}
Result:
Convert.ToString(new FormattableType()); // 0.42
new FormattableType().ToString(); // 0,42
It looks like Google recently broke something with their revoke stuff (it's started returning 400 errors for us). You now have to call
auth2.disconnect();
In our case we then have to wait a couple of seconds for the disconnect call to complete otherwise the sign-in code will re-authorise before it's done. It'd be good if google returned a promise from the disconnect method.
In your configurations, specify the port number your database is on. You can find the port number at the top left corner of phpMyAdmin. It would look something like this
const DB_HOST = 'localhost:3308';
Simply restarting Visual Studio worked for me.
Ensures the path to Xcode.app bundle is without space or strange characters. I have Xcode installed in ~/Downloads/Last Dev Tools/ folder, so with spaces and renaming the folder to LastDevTools fixed this (after resetting xcode-select -p though)
Although getattr() is elegant (and about 7x faster) method, you can get return value from the function (local, class method, module) with eval as elegant as x = eval('foo.bar')()
. And when you implement some error handling then quite securely (the same principle can be used for getattr). Example with module import and class:
# import module, call module function, pass parameters and print retured value with eval():
import random
bar = 'random.randint'
randint = eval(bar)(0,100)
print(randint) # will print random int from <0;100)
# also class method returning (or not) value(s) can be used with eval:
class Say:
def say(something='nothing'):
return something
bar = 'Say.say'
print(eval(bar)('nice to meet you too')) # will print 'nice to meet you'
When module or class does not exist (typo or anything better) then NameError is raised. When function does not exist, then AttributeError is raised. This can be used to handle errors:
# try/except block can be used to catch both errors
try:
eval('Say.talk')() # raises AttributeError because function does not exist
eval('Says.say')() # raises NameError because the class does not exist
# or the same with getattr:
getattr(Say, 'talk')() # raises AttributeError
getattr(Says, 'say')() # raises NameError
except AttributeError:
# do domething or just...
print('Function does not exist')
except NameError:
# do domething or just...
print('Module does not exist')
