There could be a global variable, likely set with argparse
from sys.argv
, that stands for whether the program should be verbose or not.
Then a decorator could be written such that if verbosity was on, then the standard input would be diverted into the null device as long as the function were to run:
import os
from contextlib import redirect_stdout
verbose = False
def louder(f):
def loud_f(*args, **kwargs):
if not verbose:
with open(os.devnull, 'w') as void:
with redirect_stdout(void):
return f(*args, **kwargs)
return f(*args, **kwargs)
return loud_f
@louder
def foo(s):
print(s*3)
foo("bar")
This answer is inspired by this code; actually, I was going to just use it as a module in my program, but I got errors I couldn't understand, so I adapted a portion of it.
The downside of this solution is that verbosity is binary, unlike with logging
, which allows for finer-tuning of how verbose the program can be.
Also, all print
calls are diverted, which might be unwanted for.
Not sure if this answers this question. But I was looking for something else. Highly recommend see this 2 minute video. If you wanted to get into more details then see docs - Handling Parameters and this link
And then if you have something like blue ocean, the choices would look something like this:
You define and access your variables like this:
pipeline {
agent any
parameters {
string(defaultValue: "TEST", description: 'What environment?', name: 'userFlag')
choice(choices: ['TESTING', 'STAGING', 'PRODUCTION'], description: 'Select field for target environment', name: 'DEPLOY_ENV')
}
stages {
stage("foo") {
steps {
echo "flag: ${params.userFlag}"
echo "flag: ${params.DEPLOY_ENV}"
}
}
}
}
Automated builds will pick up the default params. But if you do it manually then you get the option to choose.
And then assign values like this:
The example below will display a button with a title "Contact" on the navigation bar on the right. Its action calls a method named "contact" from the viewcontroller. Without this line the right button is not visible.
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Contact"
style:UIBarButtonItemStylePlain target:self action:@selector(contact:)];;
If you are decorating your method with HttpGet
, add the following using
at the top of the controller:
using System.Web.Http;
If you are using System.Web.Mvc
, then this problem can occur.
video {
width: 100% !important;
height: auto !important;
}

In terminal (while connected to the db) set output to the cvs file
1) Set field seperator to ','
:
\f ','
2) Set output format unaligned:
\a
3) Show only tuples:
\t
4) Set output:
\o '/tmp/yourOutputFile.csv'
5) Execute your query:
:select * from YOUR_TABLE
6) Output:
\o
You will then be able to find your csv file in this location:
cd /tmp
Copy it using the scp
command or edit using nano:
nano /tmp/yourOutputFile.csv
a=np.array([[1,2,3],[4,5,6]])
a.tolist()
tolist method mentioned above will return the nested Python list
Swift 2.0 Version:
private func adapteSizeLabel(label: UILabel, sizeMax: CGFloat) {
label.numberOfLines = 0
label.lineBreakMode = NSLineBreakMode.ByWordWrapping
let maximumLabelSize = CGSizeMake(label.frame.size.width, sizeMax);
let expectSize = label.sizeThatFits(maximumLabelSize)
label.frame = CGRectMake(label.frame.origin.x, label.frame.origin.y, expectSize.width, expectSize.height)
}
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.
I'm surprised there hasn't been a functional solution suggested that allows you to set the length in one line. The following is based on UnderscoreJS:
var test = _.map(_.range(4), function () { return undefined; });
console.log(test.length);
For reasons mentioned above, I'd avoid doing this unless I wanted to initialize the array to a specific value. It's interesting to note there are other libraries that implement range including Lo-dash and Lazy, which may have different performance characteristics.
Let's say your primary key is an Integer and the object you save is "ticket", then you can get it like this. When you save the object, a Serializable id is always returned
Integer id = (Integer)session.save(ticket);
And note that since Python types are only checked at runtime you can have code like:
if True:
x = 2
y = 4
else:
x = "One"
y = "Two"
print(x + y)
But I'm having trouble thinking of other ways in which the code would operate without an error because of type issues.
json.loads()
takes a JSON encoded string, not a filename. You want to use json.load()
(no s
) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open()
command produces a file object that json.load()
can then read from, to produce the decoded Python object for you. The with
statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads()
.
cleanBuildCache
no longer works.
Android Gradle plugin now utilizes Gradle cache feature
https://guides.gradle.org/using-build-cache/
TO CLEAR CACHE
Clean the cache directory to avoid any hits from previous builds
rm -rf $GRADLE_HOME/caches/build-cache-*
https://guides.gradle.org/using-build-cache/#caching_android_projects
Other digressions: see here (including edits).
Newest solution using Gradle task:
cleanBuildCache
Available via Android plugin for Gradle, revision 2.3.0 (February 2017)
Dependencies:
More info at:
https://developer.android.com/studio/build/build-cache.html#clear_the_build_cache
Build cache
Stores certain outputs that the Android plugin generates when building your project (such as unpackaged AARs and pre-dexed remote dependencies). Your clean builds are much faster while using the cache because the build system can simply reuse those cached files during subsequent builds, instead of recreating them. Projects using Android plugin 2.3.0 and higher use the build cache by default. To learn more, read Improve Build Speed with Build Cache.
NOTE: The cleanBuildCache task is not available if you disable the build cache.
Windows:
gradlew cleanBuildCache
Linux / Mac:
gradle cleanBuildCache
Android Studio / IntelliJ:
gradle tab (default on right) select and run the task or add it via the configuration window
NOTE: gradle
/ gradlew
are system specific files containing scripts. Please see the related system info how to execute the scripts:
If you can't use JodaTime, you can do the following:
Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);
int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);
Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.

Update:
If you happen to "copy" settings.py
through symlinking, @forivall's answer is better:
~user/
project1/
mysite/
settings.py
templates/
wrong.html
project2/
mysite/
settings.py -> ~user/project1/settings.py

right.html
The method above will 'see' wrong.html
while @forivall's method will see right.html
In the absense of symlinks the two answers are identical.
A bit shorter answer since PHP >= 5.3.0:
$csvFile = file('../somefile.csv');

foreach ($csvFile as $line) {
$data[] = str_getcsv($line);
}
Please, have a look on my implementation. You can wrap the following function into a service:
function(file, url) {
var fd = new FormData();
fd.append('file', file);
return $http.post(url, fd, {
transformRequest: angular.identity,
headers: { 'Content-Type': undefined }
});
}
Please notice, that file
argument is a Blob
. If you have base64
version of a file - it can be easily changed to Blob
like so:
fetch(base64).then(function(response) {
return response.blob();
}).then(console.info).catch(console.error);
First ensure that you're running the query under your user credentials, and also in the right database context.
USE YOUR_DATABASE_NAME;
Otherwise, sys.procedures won't return anything. Now run the query as below:
select * from sys.procedures p
join sys.syscomments s on p.object_id = s.id
where text like '%YOUR_TEXT%';
Another option is to use INFORMATION_SCHEMA.ROUTINES.ROUTINE_DEFINITION, but be aware that it only holds limited number of characters (i.e., first 4000 characters) of the routine.
select * from YOUR_DATABASE_NAME.INFORMATION_SCHEMA.ROUTINES
where ROUTINE_DEFINITION like '%YOUR_TEXT%';

In market client on phones at least featured apps with high ratings get to display the promotional graphic.
This is the one that shows up on top even before you start searching the market for a specific app.
See this answer from Android market forum.

Update: Both links above are now broken but the detailed information can be found here
Selected applications have the ability to be featured atop their respective categories. This is not a guaranteed feature, but uploading promotional graphics is something that we recommend.
Have you tried setting

According to Need an unordered list without any bullets, you need to add this style to the li elements.
The npm install
command will install the devDependencies
along other dependencies
when run inside a package directory, in a development environment (the default).
Use npm install --only=prod
(or --only=production
) to install only dependencies
, and not devDependencies,
regardless of the value of the NODE_ENV
environment variable.

Note: Before v3.3.0 of npm (2015-08-13), the option was called --production
, i.e. npm install --production
.
There's no way to stop execution of your code as you would do with a procedural language. You can instead make use of setTimeout and some trickery to get a parametrized timeout:
for (var i = 1; i <= 5; i++) {
var tick = function(i) {
return function() {
console.log(i);
}
};
setTimeout(tick(i), 500 * i);
}

onUserLeaveHint();
override this activity class method.This will detect the home key click . This method is called right before the activity's onPause() callback.But it will not be called when an activity is interrupted like a in-call activity comes into foreground, apart from that interruptions it will call when user click home key.
@Override
protected void onUserLeaveHint() {
super.onUserLeaveHint();
Log.d(TAG, "home key clicked");
}

Generally when people are trying to animate display: none
what they really want is:
Most popular answers use visibility
, which can only achieve the first goal, but luckily it's just as easy to achieve both by using position
.
Since position: absolute
removes the element from typing document flow spacing, you can toggle between position: absolute
and position: static
(global default), combined with opacity
. See the below example.
.content-page {_x000D_
position:absolute;_x000D_
opacity: 0;_x000D_
}_x000D_
_x000D_
.content-page.active {_x000D_
position: static;_x000D_
opacity: 1;_x000D_
transition: opacity 1s linear;_x000D_
}
_x000D_
You should use .Load

You can create an empty two dimensional list by nesting two or more square bracing or third bracket ([]
, separated by comma) with a square bracing, just like below:
Matrix = [[], []]
Now suppose you want to append 1 to Matrix[0][0]
then you type:
Matrix[0].append(1)
Now, type Matrix and hit Enter. The output will be:
[[1], []]
If you entered the following statement instead
Matrix[1].append(1)
then the Matrix would be
[[], [1]]
Use the CREATE TABLE SELECT syntax.

CREATE TABLE new_tbl SELECT * FROM orig_tbl;
The fully-qualified name is opbtained as follows:
String fqn = YourClass.class.getName();
But you need to read a classpath resource. So use
InputStream in = YourClass.getResourceAsStream("resource.txt");
Windows does not actually support passive mode.
You can send the command to the server in three different ways but that will not enable passive mode on the Windows client end.
Those arguments are for sending various commands and pasv
is not something that Microsoft thought of when they wrote it.
You will have to find a 3rd party software like WinSCP that supports command line usage and use that instead of the Windows native one.
Thanks, Max S. conda-forge worked for me as well.
Upgrading my scikit-learn from 0.19.1 to 0.19.2 in anaconda installed on Ubuntu on Google VM instance:
First, check available the packages with versions
conda list
It will show packages and their installed versions in the output:
scikit-learn 0.19.1 py36hedc7406_0
Upgrade to 0.19.2 July 2018 release.
conda config --append channels conda-forge
conda install scikit-learn=0.19.2
Now check the version installed correctly or not?
conda list
Output is:
scikit-learn 0.19.2 py36_blas_openblasha84fab4_201 [blas_openblas] conda-forge
I tried following commands:
!conda update conda
!pip install -U scikit-learn
It will install the required packages also will show in the conda list
but when try to import that package it will not work.
On the website http://scikit-learn.org/stable/install.html it is mentioned as: Warning To upgrade or uninstall scikit-learn installed with Anaconda or conda you should not use the pip.

If you can provide your image in SVG format and if it is an icon and not a photo so it can be animated with SMIL animations, then it would be definitely the superior alternative to gif images (or even other formats).
SVG images, like other image files, could be used with either standard markup or HTML <img>
element:
![image description](the_path_to/image.svg)
<img src="the_path_to/image.svg" width="128"/>

I know the question is a few years old now, but expanding on Ivella's last idea, this bash script estimates the line count of a big file within seconds or less by measuring the size of one line and extrapolating from it:
#!/bin/bash
head -2 $1 | tail -1 > $1_oneline
filesize=$(du -b $1 | cut -f -1)
linesize=$(du -b $1_oneline | cut -f -1)
rm $1_oneline
echo $(expr $filesize / $linesize)
If you name this script lines.sh
, you can call lines.sh bigfile.txt
to get the estimated number of lines. In my case (about 6 GB, export from database), the deviation from the true line count was only 3%, but ran about 1000 times faster. By the way, I used the second, not first, line as the basis, because the first line had column names and the actual data started in the second line.
A good hash function has the following properties:
Given a hash of a message it is computationally infeasible for an attacker to find another message such that their hashes are identical.
Given a pair of message, m' and m, it is computationally infeasible to find two such that that h(m) = h(m')
The two cases are not the same. In the first case, there is a pre-existing hash that you're trying to find a collision for. In the second case, you're trying to find any two messages that collide. The second task is significantly easier due to the birthday "paradox."
Where performance is not that great an issue, you should always use a secure hash function. There are very clever attacks that can be performed by forcing collisions in a hash. If you use something strong from the outset, you'll secure yourself against these.
Don't use MD5 or SHA-1 in new designs. Most cryptographers, me included, would consider them broken. The principle source of weakness in both of these designs is that the second property, which I outlined above, does not hold for these constructions. If an attacker can generate two messages, m and m', that both hash to the same value they can use these messages against you. SHA-1 and MD5 also suffer from message extension attacks, which can fatally weaken your application if you're not careful.
A more modern hash such as Whirpool is a better choice. It does not suffer from these message extension attacks and uses the same mathematics as AES uses to prove security against a variety of attacks.
Hope that helps!
You should verify that new File(".")

Based @RBT's answer above, I tried Postman native app and want to give a couple of additional details.
In the latest postman desktop app, you can find the cookies option on the extreme right:
You can see the cookies for your localhost (these cookies are linked with the cookies in your chrome browser, although the app is running natively). Also you can set the cookies for a particular domain too.
You can just use the normal setTimeout method in JavaScript.
ie...
setTimeout( function(){
// Do something after 1 second
} , 1000 );
In your example, you might want to use showStickySuccessToast
directly.
$('#lol').get(0).style.display=''
or..
$('#lol').css('display', '')
Check the format of the video you are rendering. Rendering of mp4 format started from API level 11 and the format must be mp4(H.264)

Here are brief list:
JQuery with JSON stuff. (http://www.w3schools.com/xml/xml_http.asp)
$_SESSION - probably best way
Custom cookie - will not *always* work.
HTTP headers - some proxy can block it.
database such MySQL, Postgres or something else such Redis or Memcached (e.g. similar to home-made session, "locked" by IP address)
APC - similar to database, will not *always* work.
HTTP_REFERRER
URL hash parameter , e.g. http://domain.com/page.php#param - you will need some JavaScript to collect the hash. - gmail heavy use this.
You need to replace \t
- make sure you use extended mode!
After fixing a performance issue related to the use of .is(":visible"), I would recommend against the above answers and instead use jQuery's code for deciding whether a single element is visible:
$.expr.filters.visible($("#singleElementID")[0]);
What .is does is check whether a set of elements is within another set of elements. So you will looking for your element within the entire set of visible elements on your page. Having 100 elements is pretty normal and might take a few milliseconds to search through the array of visible elements. If you're building a web app you probably have hundreds or possibly thousands. Our app was sometimes taking 100ms for $("#selector").is(":visible") since it was checking if an element was in an array of 5000 other elements.
From what I know
3 one-liners
a = 10 if <condition>
example:
a = 10 if true # a = 10
b = 10 if false # b = nil
a = 10 unless <condition>
example:
a = 10 unless false # a = 10
b = 10 unless true # b = nil
a = <condition> ? <a> : <b>
example:
a = true ? 10 : 100 # a = 10
a = false ? 10 : 100 # a = 100
I hope it helps.

Few people appear, despite the many answers to this question, to have pointed out that dictionaries are un-ordered mappings, and so (until the blessing of insertion order with Python 3.7) the idea of the "first" entry in a dictionary literally made no sense. And even an OrderedDict
can only be accessed by numerical index using such uglinesses as mydict[mydict.keys()[0]]
(Python 2 only, since in Python 3 keys()
is a non-subscriptable iterator.)
From 3.7 onwards and in practice in 3,6 as well - the new behaviour was introduced then, but not included as part of the language specification until 3.7 - iteration over the keys, values or items of a dict (and, I believe, a set also) will yield the least-recently inserted objects first. There is still no simple way to access them by numerical index of insertion.
As to the question of selecting and "formatting" items, if you know the key you want to retrieve in the dictionary you would normally use the key as a subscript to retrieve it (my_var = mydict['Apple']
).
If you really do want to be able to index the items by entry number (ignoring the fact that a particular entry's number will change as insertions are made) then the appropriate structure would probably be a list of two-element tuples. Instead of
mydict = {
'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
'Grapes':{'Arabian':'25','Indian':'20'} }
you might use:
mylist = [
('Apple', {'American':'16', 'Mexican':10, 'Chinese':5}),
('Grapes', {'Arabian': '25', 'Indian': '20'}
]
Under this regime the first entry is mylist[0]
in classic list-endexed form, and its value is ('Apple', {'American':'16', 'Mexican':10, 'Chinese':5})
. You could iterate over the whole list as follows:
for (key, value) in mylist: # unpacks to avoid tuple indexing
if key == 'Apple':
if 'American' in value:
print(value['American'])
but if you know you are looking for the key "Apple", why wouldn't you just use a dict instead?
You could introduce an additional level of indirection by cacheing the list of keys, but the complexities of keeping two data structures in synchronisation would inevitably add to the complexity of your code.
In our project, we are using a role hierarchy, while most of the above answers only aim at checking for a specific role, i.e. would only check for the role given, but not for that role and up the hierarchy.
A solution for this:
@Component
public class SpringRoleEvaluator {
@Resource(name="roleHierarchy")
private RoleHierarchy roleHierarchy;
public boolean hasRole(String role) {
UserDetails dt = AuthenticationUtils.getSessionUserDetails();
for (GrantedAuthority auth: roleHierarchy.getReachableGrantedAuthorities(dt.getAuthorities())) {
if (auth.toString().equals("ROLE_"+role)) {
return true;
}
}
return false;
}
RoleHierarchy is defined as a bean in spring-security.xml.
My solution was to switch all datetime columns to datetime2, and use datetime2 for any new columns. In other words make EF use datetime2 by default. Add this to the OnModelCreating method on your context:
modelBuilder.Properties<DateTime>().Configure(c => c.HasColumnType("datetime2"));
That will get all the DateTime and DateTime? properties on all your entities.
I needed to search for usernames that are similar to each other, and what Ned Batchelder said was incredibly helpful. However, I found I had cleaner output when I used re.compile to create my re search term:
pattern = re.compile(r"("+username+".*):(.*?):(.*?):(.*?):(.*)"
matches = re.findall(pattern, lines)
Output can be printed using the following:
print(matches[1]) # prints one whole matching line (in this case, the first line)
print(matches[1][3]) # prints the fourth character group (established with the parentheses in the regex statement) of the first line.
We use SubClass extends SuperClass only when the subclass wants to use some functionality (methods or instance variables) that is already declared in the SuperClass, or if I want to slightly modify the functionality of the SuperClass (Method overriding). But say, I have an Animal class(SuperClass) and a Dog class (SubClass) and there are few methods that I have defined in the Animal class eg. doEat(); , doSleep(); ... and many more.
Now, my Dog class can simply extend the Animal class, if i want my dog to use any of the methods declared in the Animal class I can invoke those methods by simply creating a Dog object. So this way I can guarantee that I have a dog that can eat and sleep and do whatever else I want the dog to do.
Now, imagine, one day some Cat lover comes into our workspace and she tries to extend the Animal class(cats also eat and sleep). She makes a Cat object and starts invoking the methods.
But, say, someone tries to make an object of the Animal class. You can tell how a cat sleeps, you can tell how a dog eats, you can tell how an elephant drinks. But it does not make any sense in making an object of the Animal class. Because it is a template and we do not want any general way of eating.
So instead, I will prefer to make an abstract class that no one can instantiate but can be used as a template for other classes.
So to conclude, Interface is nothing but an abstract class(a pure abstract class) which contains no method implementations but only the definitions(the templates). So whoever implements the interface just knows that they have the templates of doEat(); and doSleep(); but they have to define their own doEat(); and doSleep(); methods according to their need.
You extend only when you want to reuse some part of the SuperClass(but keep in mind, you can always override the methods of your SuperClass according to your need) and you implement when you want the templates and you want to define them on your own(according to your need).
I will share with you a piece of code: You try it with different sets of inputs and look at the results.
class AnimalClass {
public void doEat() {
System.out.println("Animal Eating...");
}
public void sleep() {
System.out.println("Animal Sleeping...");
}
}
public class Dog extends AnimalClass implements AnimalInterface, Herbi{
public static void main(String[] args) {
AnimalInterface a = new Dog();
Dog obj = new Dog();
obj.doEat();
a.eating();
obj.eating();
obj.herbiEating();
}
public void doEat() {
System.out.println("Dog eating...");
}
@Override
public void eating() {
System.out.println("Eating through an interface...");
// TODO Auto-generated method stub
}
@Override
public void herbiEating() {
System.out.println("Herbi eating through an interface...");
// TODO Auto-generated method stub
}
}
Defined Interfaces :
public interface AnimalInterface {
public void eating();
}
interface Herbi {
public void herbiEating();
}

All these solutions "sound" nice and reasonable but there is one big downside. What happens if your customer downloads your application and repeatedly presses your button?
Your MediaPlayer
will sometimes fail to play your sound if you click the button to many times.
I ran into this performance problem with the MediaPlayer
class a few days ago.
Is the MediaPlayer
class save to use? Not always. If you have short sounds it is better to use the SoundPool
class.
A save and efficient solution is the SoundPool class which offers great features and increases the performance of you application.
SoundPool is not as easy to use as the MediaPlayer
class but has some great benefits when it comes to performance and reliability.
Follow this link and learn how to use the SoundPool class in you application:

There is a simple way to solve this: you can execute php file by cron every 1 minute, and inside php executable file make "if" statement to execute when time "now" like this
<?/** suppose we have 1 hour and 1 minute inteval 01:01 */
$interval_source = "01:01";
$time_now = strtotime( "now" ) / 60;
$interval = substr($interval_source,0,2) * 60 + substr($interval_source,3,2);
if( $time_now % $interval == 0){
/** do cronjob */
}
You can try the following:

Here is a nice summary table from cppreference.com:
Here, insertion refers to any method which adds one or more elements to the container and erasure refers to any method which removes one or more elements from the container.
Is basically duplication of the other answers - but I didn't get it completely. maybe someone will finally understand it with this example now.
[ngClass]="['svg-icon', 'recolor-' + recolor, size ? 'size-' + size : '']"
will result for e.g. in
class="svg-icon recolor-red size-m"
Subclassing in Python is done as follows:
class WindowElement:
def print(self):
pass
class Button(WindowElement):
def print(self):
pass
Here is a tutorial about Python that also contains classes and subclasses.
I suppose you want to find 'simple' paths (a path is simple if no node appears in it more than once, except maybe the 1st and the last one).
Since the problem is NP-hard, you might want to do a variant of depth-first search.
Basically, generate all possible paths from A and check whether they end up in G.
The internals of the GUI system call that method, and they pass in the Graphics
parameter as a graphics context onto which you can draw.
Off the top of my head, you might try using the "margin: 0 auto" for #outer rather than #inner.
I often add background-color to my DIVs to see how they're laying out on the view. That might be a good way to diagnose what's going onn here.
Set following php parameters to same value in seconds:
session.cookie_lifetime

I solved this issue by correcting my JDBC code.
the correct JDBC string should be...
conection = DriverManager.getConnection
("jdbc:oracle:thin:@localhost:1521:xe","system","ishantyagi");
But the JDBC string I was using was ...
conection = DriverManager.getConnection
("jdbc:oracle:thin:@localhost:1521:orcl","system","ishantyagi");
So, the mistake of specifying orcl instead of xe showed this error as the SID name was wrong.
You can also use relational algebra. A bit lengthy procedure, but here it is just to understand how MAX() works:
E := pID (Table_Name)
E1 := pID (sID >= ID' ((?ID' E) ? E)) – pID (sID < ID’ ((?ID' E) ? E))
Your answer: Table_Name ? E1
Basically what you do is subtract set of ordered relation(a,b) in which a<
b from A where a, b ? A.

If, like me, you need to keep your custom flow layout's itemSize
dynamically updated based on your collection view's width, you should override your UICollectionViewFlowLayout
's prepare()
method. Here's a WWDC video demoing this technique.
class MyLayout: UICollectionViewFlowLayout {
override func prepare() {
super.prepare()
guard let collectionView = collectionView else { return }
itemSize = CGSize(width: ..., height: ...)
}
}
Use Homebrew's vim: brew install vim
Mac (as of 10.10.3 Yosemite) comes pre-installed with a system vim that does not have the clipboard
flag enabled.
You can either compile vim for yourself and enable that flag, or simply use Homebrew's vim which is setup properly.
To see this for yourself, check out the stock system vim with /usr/bin/vim --version
You'll see something like:
$ /usr/bin/vim --version

Yes, with reflection - assuming each property type implements Equals
appropriately. An alternative would be to use ReflectiveEquals
recursively for all but some known types, but that gets tricky.
public bool ReflectiveEquals(object first, object second)
{
if (first == null && second == null)
{
return true;
}
if (first == null || second == null)
{
return false;
}
Type firstType = first.GetType();
if (second.GetType() != firstType)
{
return false; // Or throw an exception
}
// This will only use public properties. Is that enough?
foreach (PropertyInfo propertyInfo in firstType.GetProperties())
{
if (propertyInfo.CanRead)
{
object firstValue = propertyInfo.GetValue(first, null);
object secondValue = propertyInfo.GetValue(second, null);
if (!object.Equals(firstValue, secondValue))
{
return false;
}
}
}
return true;
}
The WCF API in .NET handles missing parameters by returning an HTTP 404
"Endpoint Not Found" error, when using the webHttpBinding.
The 404 Not Found
can make sense if you consider your web service method name together with its parameter signature. That is, if you expose a web service method LoginUser(string, string)
and you request LoginUser(string)
, the latter is not found.
Basically this would mean that the web service method you are calling, together with the parameter signature you specified, cannot be found.
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
The 400 Bad Request
, as Gert suggested, remains a valid response code, but I think it is normally used to indicate lower-level problems. It could easily be interpreted as a malformed HTTP request, maybe missing or invalid HTTP headers, or similar.
10.4.1 400 Bad Request
The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
As Jon pointed out this is life for constraining a non-parameterless constructor. However a different solution is to use a factory pattern. This is easily constrainable
interface IFruitFactory<T> where T : BaseFruit {
T Create(int weight);
}
public void AddFruit<T>( IFruitFactory<T> factory ) where T: BaseFruit {
BaseFruit fruit = factory.Create(weight); /*new Apple(150);*/
fruit.Enlist(fruitManager);
}
Yet another option is to use a functional approach. Pass in a factory method.
public void AddFruit<T>(Func<int,T> factoryDel) where T : BaseFruit {
BaseFruit fruit = factoryDel(weight); /* new Apple(150); */
fruit.Enlist(fruitManager);
}
Here is a way which allows to remove points after a certain number of points plotted:
import matplotlib.pyplot as plt
# generate axes object
ax = plt.axes()
# set limits
plt.xlim(0,10)
plt.ylim(0,10)
for i in range(10):
# add something to axes
ax.scatter([i], [i])
ax.plot([i], [i+1], 'rx')
# draw the plot
plt.draw()
plt.pause(0.01) #is necessary for the plot to update for some reason
# start removing points if you don't want all shown
if i>2:
ax.lines[0].remove()
ax.collections[0].remove()
In my case, I was need to insert a initial value only to tell to user to select an option, so, I do like the code below:
<select ...
<option value="" ng-selected="selected">Select one option</option>
</select>
When I tryed an option with the value != of an empty string (null) the option was substituted by angular, but, when put an option like that (with null value), the select apear with this option.
Sorry by my bad english and I hope that I help in something with this.
From developer.mozilla.org docs on the String .match()
method:
The returned Array has an extra input property, which contains the original string that was parsed. In addition, it has an index property, which represents the zero-based index of the match in the string.
When dealing with a non-global regex (i.e., no g
flag on your regex), the value returned by .match()
has an index
property...all you have to do is access it.
var index = str.match(/regex/).index;
Here is an example showing it working as well:
var str = 'my string here';_x000D_
_x000D_
var index = str.match(/here/).index;_x000D_
_x000D_
alert(index); // <- 10
_x000D_
I have successfully tested this all the way back to IE5.
To avoid the fact that destroy_all
instantiates all the records and destroys them one at a time, you can use it directly from the model class.
So instead of :
u = User.find_by_name('JohnBoy')
u.usage_indexes.destroy_all
You can do :
u = User.find_by_name('JohnBoy')
UsageIndex.destroy_all "user_id = #{u.id}"
The result is one query to destroy all the associated records
Flushing the output buffers:
printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is
or
fprintf(fd, "Buffered, will be flushed");
fflush(fd); //Prints to a file
Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf()
it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf
something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.
Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf()
, so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.
I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf()
is an expensive operation (which is why it doesn't by default flush the buffer).
As far as flushing the input buffer (stdin
), you should not do that. Flushing stdin
is undefined behavior according to the C11 standard §7.21.5.2 part 2:
If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.
On some systems, Linux being one as you can see in the man page for fflush()
, there's a defined behavior but it's system dependent so your code will not be portable.
Now if you're worried about garbage "stuck" in the input buffer you can use fpurge()
on that.
See here for more on fflush()
and fpurge()
To call GET,POST,DELETE,PUT All kind of request, i have created one common function
function CallAPI($method, $api, $data) {
$url = "http://localhost:82/slimdemo/RESTAPI/" . $api;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
switch ($method) {
case "GET":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
break;
case "POST":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
break;
case "PUT":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
break;
case "DELETE":
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
break;
}
$response = curl_exec($curl);
$data = json_decode($response);
/* Check for 404 (file not found). */
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
// Check the HTTP Status code
switch ($httpCode) {
case 200:
$error_status = "200: Success";
return ($data);
break;
case 404:
$error_status = "404: API Not found";
break;
case 500:
$error_status = "500: servers replied with an error.";
break;
case 502:
$error_status = "502: servers may be down or being upgraded. Hopefully they'll be OK soon!";
break;
case 503:
$error_status = "503: service unavailable. Hopefully they'll be OK soon!";
break;
default:
$error_status = "Undocumented error: " . $httpCode . " : " . curl_error($curl);
break;
}
curl_close($curl);
echo $error_status;
die;
}
CALL Delete Method
$data = array('id'=>$_GET['did']);
$result = CallAPI('DELETE', "DeleteCategory", $data);
CALL Post Method
$data = array('title'=>$_POST['txtcategory'],'description'=>$_POST['txtdesc']);
$result = CallAPI('POST', "InsertCategory", $data);
CALL Get Method
$data = array('id'=>$_GET['eid']);
$result = CallAPI('GET', "GetCategoryById", $data);
CALL Put Method
$data = array('id'=>$_REQUEST['eid'],m'title'=>$_REQUEST['txtcategory'],'description'=>$_REQUEST['txtdesc']);
$result = CallAPI('POST', "UpdateCategory", $data);
You can use following code:
sendButton.enabled = YES;
sendButton.alpha = 1.0;
or
sendButton.enabled = NO;
sendButton.alpha = 0.5;
you could also just have a return div like the one below and use the built in template literals of Javascript :
const tifs = {1: 'Joe', 2: 'Jane'};
return(
<div>
{Object.keys(tifOptions).map((key)=>(
<p>{paragraphs[`${key}`]}</p>
))}
</div>
)
I use this in php.
private static function ifTableExists(string $database, string $table): bool
{
$query = DB::select("
SELECT
IF( EXISTS
(SELECT * FROM information_schema.COLUMNS
WHERE TABLE_SCHEMA = '$database'
AND TABLE_NAME = '$table'
LIMIT 1),
1, 0)
AS if_exists
");
return $query[0]->if_exists == 1;
}
You can stop the running tomcat server by doing the following steps:
Step 1: go to your tomcat installation path (/bin) in your Windows system
Step 2: open cmd for that bin directory (you can easily do this by typing "cmd" at that directory )
Step 3: Run "Tomcat7.exe stop"
This will stop all running instances of tomcat server and now you can start server from your eclipse IDE.
Since MockMvcRequestBuilders#fileUpload
is deprecated, you'll want to use MockMvcRequestBuilders#multipart(String, Object...)
which returns a MockMultipartHttpServletRequestBuilder
. Then chain a bunch of file(MockMultipartFile)
calls.
Here's a working example. Given a @Controller
@Controller
public class NewController {
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
public String saveAuto(
@RequestPart(value = "json") JsonPojo pojo,
@RequestParam(value = "some-random") String random,
@RequestParam(value = "data", required = false) List<MultipartFile> files) {
System.out.println(random);
System.out.println(pojo.getJson());
for (MultipartFile file : files) {
System.out.println(file.getOriginalFilename());
}
return "success";
}
static class JsonPojo {
private String json;
public String getJson() {
return json;
}
public void setJson(String json) {
this.json = json;
}
}
}
and a unit test
@WebAppConfiguration
@ContextConfiguration(classes = WebConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class Example {
@Autowired
private WebApplicationContext webApplicationContext;
@Test
public void test() throws Exception {
MockMultipartFile firstFile = new MockMultipartFile("data", "filename.txt", "text/plain", "some xml".getBytes());
MockMultipartFile secondFile = new MockMultipartFile("data", "other-file-name.data", "text/plain", "some other type".getBytes());
MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json", "{\"json\": \"someValue\"}".getBytes());
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
mockMvc.perform(MockMvcRequestBuilders.multipart("/upload")
.file(firstFile)
.file(secondFile)
.file(jsonFile)
.param("some-random", "4"))
.andExpect(status().is(200))
.andExpect(content().string("success"));
}
}
And the @Configuration
class
@Configuration
@ComponentScan({ "test.controllers" })
@EnableWebMvc
public class WebConfig extends WebMvcConfigurationSupport {
@Bean
public MultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
return multipartResolver;
}
}
The test should pass and give you output of
4 // from param
someValue // from json file
filename.txt // from first file
other-file-name.data // from second file
The thing to note is that you are sending the JSON just like any other multipart file, except with a different content type.
This looks a little better than your previous version but get rid of that .Activate on that line and see if you still get that error.
Dim sh1 As Worksheet
set sh1 = Workbooks.Add(filenum(lngPosition) & ".csv")
Creates a worksheet object. Not until you create that object do you want to start working with it. Once you have that object you can do the following:
sh1.Range("A69").Paste
sh1.Range("A69").Select
The sh1. explicitely tells Excel which object you are saying to work with... otherwise if you start selecting other worksheets while this code is running you could wind up pasting data to the wrong place.
DELETE TableA

GNU Trove support this but not using generics. http://trove4j.sourceforge.net/javadocs/gnu/trove/TObjectIntHashMap.html
from the website: Latest version supports:
and others, so try it now!
SELECT COALESCE(prereq, '') FROM test
Coalesce will return the first non-null argument passed to it from left to right. If all arguemnts are null, it'll return null, but we're forcing an empty string there, so no null values will be returned.
Also note that the COALESCE operator is supported in standard SQL. This is not the case of IFNULL. So it is a good practice to get use the former. Additionally, bear in mind that COALESCE supports more than 2 parameters and it will iterate over them until a non-null coincidence is found.
None of the above solutions worked for me on Windows 8
But the following command works fine
SHIFT + Q
ng-bind
is also safer because it represents html
as a string.
So for example, '<script on*=maliciousCode()></script>'
will be displayed as a string and not be executed.
In some cases one wants to both save and print a base r plot. I spent a bit of time and came up with this utility function:
x = 1:10
basesave = function(expr, filename, print=T) {
#extension
exten = stringr::str_match(filename, "\\.(\\w+)$")[, 2]
switch(exten,
png = {
png(filename)
eval(expr, envir = parent.frame())
dev.off()
},
{stop("filetype not recognized")})
#print?
if (print) eval(expr, envir = parent.frame())
invisible(NULL)
}
#plots, but doesn't save
plot(x)
#saves, but doesn't plot
png("test.png")
plot(x)
dev.off()
#both
basesave(quote(plot(x)), "test.png")
#works with pipe too
quote(plot(x)) %>% basesave("test.png")
Note that one must use quote
, otherwise the plot(x)
call is run in the global environment and NULL
gets passed to basesave()
.
It's worth noting also that the yank registers are the same as the macro buffers. In other words, you can simply write out your whole command in your document (including your pasted snippet), then "by
to yank it to the b
register, and then run it with @b
.
Use the keyword and
, not &
because &
is a bit operator.
Be careful with this... just so you know, in Java and C++, the &
operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&
. Similarly |
is a bit operator, and ||
is a boolean operator. In Python and
and or
are used for boolean comparisons.
JAVACMD
is an Ant specific environment variable. Ant doc says:
JAVACMD—full path of the Java executable. Use this to invoke a different JVM than JAVA_HOME/bin/java(.exe).
So, if your java.exe
full path is: C:\Program Files\Java\jdk1.8.0_211\bin\java.exe
, create a new environment variable called JAVACMD
and set its value to the mentioned path (including \java.exe
). Note that you need to close and reopen your terminal (cmd, Powershell, etc) so the new environment variable takes effect.
The easiest solution is to just run your own counter thus:
int i = 0;
for (String s : stringArray) {
doSomethingWith(s, i);
i++;
}
The reason for this is because there's no actual guarantee that items in a collection (which that variant of for
iterates over) even have an index, or even have a defined order (some collections may change the order when you add or remove elements).
See for example, the following code:
import java.util.*;
public class TestApp {
public static void AddAndDump(AbstractSet<String> set, String str) {
System.out.println("Adding [" + str + "]");
set.add(str);
int i = 0;
for(String s : set) {
System.out.println(" " + i + ": " + s);
i++;
}
}
public static void main(String[] args) {
AbstractSet<String> coll = new HashSet<String>();
AddAndDump(coll, "Hello");
AddAndDump(coll, "My");
AddAndDump(coll, "Name");
AddAndDump(coll, "Is");
AddAndDump(coll, "Pax");
}
}
When you run that, you can see something like:
Adding [Hello]
0: Hello
Adding [My]
0: Hello
1: My
Adding [Name]
0: Hello
1: My
2: Name
Adding [Is]
0: Hello
1: Is
2: My
3: Name
Adding [Pax]
0: Hello
1: Pax
2: Is
3: My
4: Name
indicating that, rightly so, order is not considered a salient feature of a set.
There are other ways to do it without a manual counter but it's a fair bit of work for dubious benefit.
this short answer might help someone who is looking to do. add this simple code in your code
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:editable="false"
android:focusable="false"
android:singleLine="true" />
If you use RGBA for modern browsers you don't need let older IEs use only the non-transparent version of the given color with RGB.
If you don't stick to CSS-only solutions, give CSS3PIE a try. With this syntax you can see exactly the same result in older IEs that you see in modern browsers:
div {
-pie-background: rgba(223,231,233,0.8);
behavior: url(../PIE.htc);
}
$("#header").attr('tabindex', -1).focus();
@Override
public void onClick(View v)
{
switch (v.getId())
{
case R.id.:
break;
case R.id.:
break;
default:
break;
}
}
Since Joda is getting faded, someone might want to convert LocaltDate
to LocalDateTime
in Java 8. In Java 8 LocalDateTime
it will give a way to create a LocalDateTime
instance using a LocalDate
and LocalTime
. Check here.
public static LocalDateTime of(LocalDate date, LocalTime time)
Sample would be,
// just to create a sample LocalDate
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMdd");
LocalDate ld = LocalDate.parse("20180306", dtf);
// convert ld into a LocalDateTime
// We need to specify the LocalTime component here as well, it can be any accepted value
LocalDateTime ldt = LocalDateTime.of(ld, LocalTime.of(0,0)); // 2018-03-06T00:00
Just for reference, For getting the epoch seconds below can be used,
ZoneId zoneId = ZoneId.systemDefault();
long epoch = ldt.atZone(zoneId).toEpochSecond();
// If you only care about UTC
long epochUTC = ldt.toEpochSecond(ZoneOffset.UTC);
I experienced the same issue, it was related to security not being granted to part of the tables. review your user has access to the databases/ tables/views/functions etc used by the report.
If you removed the make all
line from your "fresh" target:
fresh :
rm -f *.o $(EXEC)
clear
You could simply run the command make fresh all
, which will execute as make fresh; make all
.
Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.
Check if all the parameters of functions are defined before they are called. I faced this problem while practicing Kaggle.
This is how I do it.
#To update your local.
git fetch --all
this will fetch everything from the remote, so when you check difference, it will compare the difference with the remote branch.
#to list all branches
git branch -a
the above command will display all the branches.
#to go to the branch you want to check difference
git checkout <branch_name>
#to check on which branch you are in, use
git branch
(or)
git status
Now, you can check difference as follows.
git diff origin/<branch_name>
this will compare your local branch with the remote branch
Let's create a decently complicated stacktrace, in order to demonstrate that we get the full stacktrace:
def raise_error():
raise RuntimeError('something bad happened!')
def do_something_that_might_error():
raise_error()
A best practice is to have a logger set up for your module. It will know the name of the module and be able to change levels (among other attributes, such as handlers)
import logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)
And we can use this logger to get the error:
try:
do_something_that_might_error()
except Exception as error:
logger.exception(error)
Which logs:
ERROR:__main__:something bad happened!
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
File "<stdin>", line 2, in do_something_that_might_error
File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!
And so we get the same output as when we have an error:
>>> do_something_that_might_error()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in do_something_that_might_error
File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!
If you really just want the string, use the traceback.format_exc
function instead, demonstrating logging the string here:
import traceback
try:
do_something_that_might_error()
except Exception as error:
just_the_string = traceback.format_exc()
logger.debug(just_the_string)
Which logs:
DEBUG:__main__:Traceback (most recent call last):
File "<stdin>", line 2, in <module>
File "<stdin>", line 2, in do_something_that_might_error
File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!
You can also try
SELECT * FROM mytable WHERE age IN (SELECT MAX(age) FROM mytable GROUP BY `Group`) ;
You can use google's chart api to generate charts.
Look at the traceback:
Traceback (most recent call last):
File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
out = iter(out)
TypeError: 'bool' object is not iterable
Your code isn't iterating the value, but the code receiving it is.
The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)
) or enclose it in a tuple ((False,)
).
Always read the traceback: it's correct, and it's helpful.
This worked for me
<select ng-init="basicProfile.casteId" ng-model="basicProfile.casteId" class="form-control">
<option value="0">Select Caste....</option>
<option data-ng-repeat="option in formCastes" value="{{option.id}}">{{option.casteName}}</option>
</select>
Here are a couple of quick functions I use when bash scripting Kafka Data Load into Demo Environments. In this example I use HDP with no security, but it is easily modified to other environments and intended to be quick and functional rather than particularly robust.
The first retrieves the address of the first ZooKeeper node from the config:
ZKS1=$(cat /usr/hdp/current/zookeeper-client/conf/zoo.cfg | grep server.1)
[[ ${ZKS1} =~ server.1=(.*?):[0-9]*:[0-9]* ]]
export ZKADDR=${BASH_REMATCH[1]}:2181
echo "using ZooKeeper Server $ZKADDR"
The second retrieves the Broker IDs from ZooKeeper:
echo "Fetching list of Kafka Brokers"
export BROKERIDS=$(/usr/hdp/current/kafka-broker/bin/zookeeper-shell.sh ${ZKADDR} <<< 'ls /brokers/ids' | tail -1)
export BROKERIDS=${BROKERIDS//[!0-9 ]/}
echo "Found Kafka Broker IDS: $BROKERIDS"
The third parses ZooKeeper again to retrieve the list of Kafka Brokers Host:port ready for use in the command-line client:
unset BROKERS
for i in $BROKERIDS
do
DETAIL=$(/usr/hdp/current/kafka-broker/bin/zookeeper-shell.sh ${ZKADDR} <<< "get /brokers/ids/$i")
[[ $DETAIL =~ PLAINTEXT:\/\/(.*?)\"\] ]]
if [ -z ${BROKERS+x} ]; then BROKERS=${BASH_REMATCH[1]}; else
BROKERS="${BROKERS},${BASH_REMATCH[1]}"; fi
done
echo "Found Brokerlist: $BROKERS"
For native code it's probably best to use Dependency Walker. It also possible to use dumpbin command line utility that comes with Visual Studio.
The other answers have covered the direct question well, but you may also be interested in using set -e
. With that, any command that fails (outside of specific contexts like if
tests) will cause the script to abort. For certain scripts, it's very useful.
Java Collection should be collections of Object only.
List<Integer> integerList = new ArrayList<Integer>();
more from JAVA wrapper classes here!
U can directly save and get int to/from integerList as,
integerList.add(intValue);
int intValue = integerList.get(i)
You can use the Median of Medians algorithm to find median of an unsorted array in linear time.
Try the following :
try
{
var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();
string body = "Your registration has been done successfully. Thank you.";
MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
message.Subject = "Thank You For Your Registration";
message.IsBodyHtml = true;
message.Body = body;
var client = new SmtpClient();
client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
client.Host = smtpHost;
client.EnableSsl = true;
client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
client.Send(message);
}
catch (Exception ex)
{
throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}
And then in you web.config add the following in between
<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>
Taken from Bash shell script split array:
IN="[email protected];[email protected]"
arrIN=(${IN//;/ })
echo ${arrIN[1]} # Output: [email protected]
Explanation:
This construction replaces all occurrences of ';'
(the initial //
means global replace) in the string IN
with ' '
(a single space), then interprets the space-delimited string as an array (that's what the surrounding parentheses do).
The syntax used inside of the curly braces to replace each ';'
character with a ' '
character is called Parameter Expansion.
There are some common gotchas:
IFS=':'; arrIN=($IN); unset IFS;
IFS=$'\n'; arrIN=($IN); unset IFS;
First Add a reference of System.Configuration
to your page.
using System.Configuration;
Then According to your app.config get the connection string as follow.
string conStr = ConfigurationManager.ConnectionStrings["Test"].ToString();
That's it now you have your connection string in your hand and you can use it.
It seems that you are asking multiple things. To answer them:
You can extract the numbers by catching them in capturing parentheses:
.*(\d+) rofl.*
and using $1
to get the string out (.*
is for "the rest before and after on the same line)
With sed as example, the idea becomes this to replace all strings in a file with only the matching number:
sed -e 's/.*(\d+) rofl.*/$1/g' inputFileName > outputFileName
or:
echo "12 BBQ ,45 rofl, 89 lol" | sed -e 's/.*(\d+) rofl.*/$1/g'
Here is the complete solution
html code,
create the text anf file upload fields as shown below
<div class="form-group">
<div>
<label for="usr">User Name:</label>
<input type="text" id="usr" ng-model="model.username">
</div>
<div>
<label for="pwd">Password:</label>
<input type="password" id="pwd" ng-model="model.password">
</div><hr>
<div>
<div class="col-lg-6">
<input type="file" file-model="model.somefile"/>
</div>
</div>
<div>
<label for="dob">Dob:</label>
<input type="date" id="dob" ng-model="model.dob">
</div>
<div>
<label for="email">Email:</label>
<input type="email"id="email" ng-model="model.email">
</div>
<button type="submit" ng-click="saveData(model)" >Submit</button>
directive code
create a filemodel directive to parse file
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
Service code
append the file and fields to form data and do $http.post as shown below remember to keep 'Content-Type': undefined
.service('fileUploadService', ['$http', function ($http) {
this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
var myFormData = new FormData();
myFormData.append('file', file);
myFormData.append('username', username);
myFormData.append('password', password);
myFormData.append('dob', dob);
myFormData.append('email', email);
$http.post(uploadUrl, myFormData, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}
}]);
In controller
Now in controller call the service by sending required data to be appended in parameters,
$scope.saveData = function(model){
var file = model.myFile;
var uploadUrl = "/api/createUsers";
fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};
EDIT: URIUtil
is no longer available in more recent versions, better answer at Java - encode URL or by Mr. Sindi in this thread.
URIUtil
of Apache httpclient is really useful, although there are some alternatives
URIUtil.encodeQuery(url);
For example, it encodes space as "+" instead of "%20"
Both are perfectly valid in the right context. Although if you really preferred you could issue a string replace.
This may be overkill for what you're looking for, but there is an npm package called marky
that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer.
You just need to install it via npm
and then import the dependency anywhere you'd like to use it.
Here is a link to the npm
package:
https://www.npmjs.com/package/marky
An example of use after installing via npm would be as follows:
import * as _M from 'marky';
@Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit {
Marky = _M;
}
constructor() {}
ngOnInit() {}
startTimer(key: string) {
this.Marky.mark(key);
}
stopTimer(key: string) {
this.Marky.stop(key);
}
key
is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.
Along the lines of Guava, Apache Commons Lang has ExceptionUtils.getFullStackTrace
in org.apache.commons.lang.exception
. From a prior answer on StackOverflow.
I have come across this error when the app resides on a network share, and the device (laptop, tablet, ...) becomes disconnected from the network while the app is in use. In my case, it was due to a Surface tablet going out of wireless range. No problems after installing a better WAP.
Allowing the execution flow to leave main
by returning a value or allowing execution to reach the end of the function is the way a program should terminate except under unrecoverable circumstances. Returning a value is optional in C++, but I typically prefer to return EXIT_SUCCESS
found in cstdlib (a platform-specific value that indicates the program executed successfully).
#include <cstdlib>
int main(int argc, char *argv[]) {
...
return EXIT_SUCCESS;
}
If, however, your program reaches an unrecoverable state, it should throw an exception. It's important to realise the implications of doing so, however. There are no widely-accepted best practices for deciding what should or should not be an exception, but there are some general rules you need to be aware of.
For example, throwing an exception from a destructor is nearly always a terrible idea because the object being destroyed might have been destroyed because an exception had already been thrown. If a second exception is thrown, terminate
is called and your program will halt without any further clean-up having been performed. You can use uncaught_exception
to determine if it's safe, but it's generally better practice to never allow exceptions to leave a destructor.
While it's generally always possible for functions you call but didn't write to throw exceptions (for example, new
will throw std::bad_alloc
if it can't allocate enough memory), it's often difficult for beginner programmers to keep track of or even know about all of the special rules surrounding exceptions in C++. For this reason, I recommend only using them in situations where there's no sensible way for your program to continue execution.
#include <stdexcept>
#include <cstdlib>
#include <iostream>
int foo(int i) {
if (i != 5) {
throw std::runtime_error("foo: i is not 5!");
}
return i * 2;
}
int main(int argc, char *argv[]) {
try {
foo(3);
}
catch (const std::exception &e) {
std::cout << e.what() << std::endl;
return EXIT_FAILURE;
}
return EXIT_SUCCESS;
}
exit
is a hold-over from C and may result in objects with automatic storage to not be cleaned up properly. abort
and terminate
effectively causes the program to commit suicide and definitely won't clean up resources.
Whatever you do, don't use exceptions, exit
, or abort
/terminate
as a crutch to get around writing a properly structured program. Save them for exceptional situations.
I do like that:
<script>
function isIE () {
var myNav = navigator.userAgent.toLowerCase();
return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}
var ua = window.navigator.userAgent;
//Internet Explorer | if | 9-11
if (isIE () == 9) {
alert("Shut down this junk! | IE 9");
} else if (isIE () == 10){
alert("Shut down this junk! | IE 10");
} else if (ua.indexOf("Trident/7.0") > 0) {
alert("Shut down this junk! | IE 11");
}else{
alert("Thank god it's not IE!");
}
</script>
If you want to create a .war file you can deploy to a Tomcat instance using the Manager app, create a folder, put all your files in that folder (including an index.html file) move your terminal window into that folder, and execute the following command:
zip -r <AppName>.war *
I've tested it with Tomcat 8 on the Mac, but it should work anywhere
The Return View(model) returns you error because you don't fill the model with the values in your post method and the model data for the dropdown is empty. Please provide the Get method to explain further how to manage displaying the error. In order to the error to be shown you should use this:
[HttpPost]
public ActionResult form_edit(FormModels model)
{
if(ModelState.IsValid())
{
--- operations
return Redirect("OtherAction", "SomeController");
}
// here you can use a little trick
//fill the model property that holds the information for the dropdown with the data
// you haven't provided the get method but it should look something like this
model.Countries = ... some data goes here;
model.dd_value = ... some other data;
model.dd_text = ... other data;
ModelState.AddModelError("", "adfdghdghgdhgdhdgda");
return View(model);
}
and then in the view just use :
@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController
@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{
<table>
<tr>
<td>
@Html.ValidationSummary(true)
</td>
</tr>
<tr>
<th>
@Html.DisplayNameFor(model => model.content_name)
@Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")
</th>
</tr>
</table>
<table>
<tr>
<td>
<input type="submit" value="Submit" />
</td>
</tr>
</table>
}
This should work okay.
If you just use RedirectToAction it will redirect you to the get method --> you will have no error but the view will be just reloaded and no error would be shown.
other way around is that you can pass the error not by ModelState.AddError, but with ViewData["error"] like this:
[HttpPost]
public ActionResult form_edit(FormModels model)
{
TempData["error"] = "someErrorMessage";
return RedirectToAction("form_Post", "Form");
}
[HttpGet]
public ActionResult form_edit()
{
do stuff here ----
ViewData["error"] = TempData["error"];
return View();
}
@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController
@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{
<table>
<tr>
<td>
<div>@ViewData["error"]</div>
</td>
</tr>
<tr>
<th>
@Html.DisplayNameFor(model => model.content_name)
@Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")
</th>
</tr>
</table>
<table>
<tr>
<td>
<input type="submit" value="Submit" />
</td>
</tr>
</table>
}
If you only want to replace some characters you could use this:
import re
print re.sub(r'([\.\\\+\*\?\[\^\]\$\(\)\{\}\!\<\>\|\:\-])', r'\\\1', "example string.")
You can see e.gs. in the documentation demonstrating joris answer. Also from the documentation, you could also set subplots=True
and layout=(,)
within the pandas plot
function:
df.plot(subplots=True, layout=(1,2))
You could also use fig.add_subplot()
which takes subplot grid parameters such as 221, 222, 223, 224, etc. as described in the post here. Nice examples of plot on pandas data frame, including subplots, can be seen in this ipython notebook.
In IntelliJ IDEA 2016.1.1:
You may try this:
Page::where('id', $id)->update(array('image' => 'asdasd'));
There are other ways too but no need to use Page::find($id);
in this case. But if you use find()
then you may try it like this:
$page = Page::find($id);
// Make sure you've got the Page model
if($page) {
$page->image = 'imagepath';
$page->save();
}
Also you may use:
$page = Page::findOrFail($id);
So, it'll throw an exception if the model with that id was not found.
If you looking for a simple way of datetime
to string conversion and can omit the format. You can convert datetime
object to str
and then use array slicing.
In [1]: from datetime import datetime
In [2]: now = datetime.now()
In [3]: str(now)
Out[3]: '2019-04-26 18:03:50.941332'
In [5]: str(now)[:10]
Out[5]: '2019-04-26'
In [6]: str(now)[:19]
Out[6]: '2019-04-26 18:03:50'
But note the following thing. If other solutions will rise an AttributeError
when the variable is None
in this case you will receive a 'None'
string.
In [9]: str(None)[:19]
Out[9]: 'None'
In my case, I was transport class component from parent and use it inside as a prop var, using typescript and Formik, and run well like this:
Parent 1
import Parent2 from './../components/Parent2/parent2'
import Parent3 from './../components/Parent3/parent3'
export default class Parent1 extends React.Component {
render(){
<React.Fragment>
<Parent2 componentToFormik={Parent3} />
</React.Fragment>
}
}
Parent 2
export default class Parent2 extends React.Component{
render(){
const { componentToFormik } = this.props
return(
<Formik
render={(formikProps) => {
return(
<React.fragment>
{(new componentToFormik(formikProps)).render()}
</React.fragment>
)
}}
/>
)
}
}
On git version 2.17.1
, there isn't a built-in flag to achieve this purpose.
Here's an example command to filter out the filename and line numbers from an unified diff:
git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? @@@)' | paste -s -d':'
For example, the unified diff:
$ git diff --unified=0
diff --cc foobar
index b436f31,df63c58..0000000
--- a/foobar
+++ b/foobar
@@@ -1,2 -1,2 +1,6 @@@ Line abov
++<<<<<<< HEAD
+bar
++=======
+ foo
++>>>>>>> Commit message
Will result in:
? git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? @@@)' | paste -s -d':'
foobar:1
To match the output of commands in common grep match results:
$ git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? )| @@@.*' | sed -e '0~3{s/ @@@[ ]\?//}' | sed '2~3 s/$/\n1/g' | sed "N;N;N;s/\n/:/g"
foobar:1:1:Line abov
grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? )
: Match filename from diff --cc <filename>
OR Match line number from @@@ <from-file-range> <from-file-range> <to-file-range>
OR Match remaining text after @@@
.sed -e '0~3{s/ @@@[ ]\?//}'
: Remove @@@[ ]\?
from every 3rd line to get the optional 1 line context before ++<<<<<<< HEAD
.sed '2~3 s/$/\n1/g'
: Add \n1
every 3 lines between the 2nd and 3rd line for the column number.sed "N;N;N;s/\n/:/g"
: Join every 3 lines with a :
.**Step1**: Go to xampp/phpMyAdmin/config.inc.php
**Step2**: Search this: $cfg['Servers'][$i]['host'] = '127.0.0.1';
**Step3**: Replace with $cfg['Servers'][$i]['host'] = '127.0.0.1:3307';
Here 3307 will be change with your mysql port number, in my case it is 3307. Most of the times it will be 3306.
You can check your mysql port number from here : xampp/mysql/bin/my.ini

I had the same problem, two list boxes and two buttons.
The data in the list boxes was being loaded from a database and you could move items between boxes by clicking the buttons.
I was getting an invalid postback.
turns out that it was the data had carriage return line feeds in it which you cannot see when displayed in the list box.
worked fine in every browser except IE 10 and IE 11.
Remove the carriage return line feeds and all works fine.
As suggested you can change the pivot table content and paste as values.
But if you want to change the values dynamically the easiest way I found is
Go To Insert->create pivot table
Now in the dialog box in the input data field select the cells of your previous pivot table.

Aria can be used to add content in the code which helps screen reader users understand role, state, label and purpose of the control
Aria does not change anything visually. (Aria is scared of designers too).
aria-label
aria-label attribute is used to communicate the label to screen reader users. Usually search input field does not have visual label (thanks to designers). aria-label can be used to communicate the label of control to screen reader users
How To Use:
<input type="edit" aria-label="search" placeholder="search">
There is no visual change in application. But screen readers can understand the purpose of control
aria-labelledby
Both aria-label and aria-labelledby is used to communicate the label. But aria-labelledby can be used to reference any label already present in the page whereas aria-label is used to communicate the label which i not displayed visually
Approach 1:
<span id="sd">Search</span>
<input type="text" aria-labelledby="sd">
Approach 2:
aria-labelledby can also be used to combine two labels for screen reader users
<span id="de">Billing Address</span>
<span id="sd">First Name</span>
<input type="text" aria-labelledby="de sd">
The conversion you need requires the offset from UTC/Greewich, or a time-zone.
If you have an offset, there is a dedicated method on LocalDateTime
for this task:
long epochSec = localDateTime.toEpochSecond(zoneOffset);
If you only have a ZoneId
then you can obtain the ZoneOffset
from the ZoneId
:
ZoneOffset zoneOffset = ZoneId.of("Europe/Oslo").getRules().getOffset(ldt);
But you may find conversion via ZonedDateTime
simpler:
long epochSec = ldt.atZone(zoneId).toEpochSecond();
You can configure it globally:
git config --global core.filemode false
If the above doesn't work for you, the reason might be your local configuration overrides the global configuration.
Remove your local configuration to make the global configuration take effect:
git config --unset core.filemode
Alternatively, you could change your local configuration to the right value:
git config core.filemode false
As far as I can tell, whether you throw an exception, or you return Request.CreateErrorResponse, the result is the same. If you look at the source code for System.Web.Http.dll, you will see as much. Take a look at this general summary, and a very similar solution that I have made: Web Api, HttpError, and the behavior of exceptions
you can use PATTERN:
<input class="form-control" minlength="1" pattern="[0-9]*" [(ngModel)]="value" #name="ngModel">
<div *ngIf="name.invalid && (name.dirty || name.touched)" class="text-danger">
<div *ngIf="name.errors?.pattern">Is not a number</div>
</div>
My guess is that you're trying to squeeze a number greater than 99999.99 into your decimal fields. Changing it to (8,3) isn't going to do anything if it's greater than 99999.999 - you need to increase the number of digits before the decimal. You can do this by increasing the precision (which is the total number of digits before and after the decimal). You can leave the scale the same unless you need to alter how many decimal places to store. Try decimal(9,2)
or decimal(10,2)
or whatever.
You can test this by commenting out the insert #temp
and see what numbers the select statement is giving you and see if they are bigger than your column can handle.
exception.toString
does not give you the StackTrace, it only returns
a short description of this throwable. The result is the concatenation of:
* the name of the class of this object * ": " (a colon and a space) * the result of invoking this object's getLocalizedMessage() method
Use exception.printStackTrace
instead to output the StackTrace.
html code:
<!DOCTYPE html>
<html>
<head><title>this is your web page</title></head>
<body>
<div class = "nicecolor"></div>
</body>
</html>
css code:
.nicecolor {
color:red;
width:200px;
height:200px;
}
.nicecolor:hover {
color:blue;
}
and thats how youll change your div from red to blue by hovering over it.
Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.
The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.
My personal preference is to go with a bare constructor and set any properties as part of the declaration.
Person p=new Person()
{
Name = "Han Solo",
Age = 39
};
This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).
If the vectors are not showing individually set colors using fillColor then they may be being set to a default widget parameter.
Try adding app:itemIconTint="@color/lime"
to activity_main.xml to set a default color type for the widget icons.

"Edit -> EOL Conversion". You can convert to Windows/Linux/Mac EOL there. The current format is displayed in the status bar.
You can use the ROWLOCK hint, but AFAIK SQL may decide to escalate it if it runs low on resources
ROWLOCK Specifies that row locks are taken when page or table locks are ordinarily taken. When specified in transactions operating at the SNAPSHOT isolation level, row locks are not taken unless ROWLOCK is combined with other table hints that require locks, such as UPDLOCK and HOLDLOCK.
and
Lock hints ROWLOCK, UPDLOCK, AND XLOCK that acquire row-level locks may place locks on index keys rather than the actual data rows. For example, if a table has a nonclustered index, and a SELECT statement using a lock hint is handled by a covering index, a lock is acquired on the index key in the covering index rather than on the data row in the base table.
And finally this gives a pretty in-depth explanation about lock escalation in SQL Server 2005 which was changed in SQL Server 2008.
There is also, the very in depth: Locking in The Database Engine (in books online)
So, in general
UPDATE
Employees WITH (ROWLOCK)
SET Name='Mr Bean'
WHERE Age>93
Should be ok, but depending on the indexes and load on the server it may end up escalating to a page lock.
I extended @Pratik Sharmas code to use BigDecimal objects instead of ints so that it can accept larger numbers, and account for any formatting in the EditText that isn't a number (like currency formatting i.e. spaces, commas and periods)
EDIT: note that this implementation has 2 as the minimum significant figures set on the BigDecimal (see the MIN_SIG_FIG constant) as I used it for currency, so there was always 2 leading numbers before the decimal point. Alter the MIN_SIG_FIG constant as necessary for your own implementation.
public class InputFilterMinMax implements InputFilter {
private static final int MIN_SIG_FIG = 2;
private BigDecimal min, max;
public InputFilterMinMax(BigDecimal min, BigDecimal max) {
this.min = min;
this.max = max;
}
public InputFilterMinMax(String min, String max) {
this.min = new BigDecimal(min);
this.max = new BigDecimal(max);
}
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart,
int dend) {
try {
BigDecimal input = formatStringToBigDecimal(dest.toString()
+ source.toString());
if (isInRange(min, max, input)) {
return null;
}
} catch (NumberFormatException nfe) {
}
return "";
}
private boolean isInRange(BigDecimal a, BigDecimal b, BigDecimal c) {
return b.compareTo(a) > 0 ? c.compareTo(a) >= 0 && c.compareTo(b) <= 0
: c.compareTo(b) >= 0 && c.compareTo(a) <= 0;
}
public static BigDecimal formatStringToBigDecimal(String n) {
Number number = null;
try {
number = getDefaultNumberFormat().parse(n.replaceAll("[^\\d]", ""));
BigDecimal parsed = new BigDecimal(number.doubleValue()).divide(new BigDecimal(100), 2,
BigDecimal.ROUND_UNNECESSARY);
return parsed;
} catch (ParseException e) {
return new BigDecimal(0);
}
}
private static NumberFormat getDefaultNumberFormat() {
NumberFormat nf = NumberFormat.getInstance(Locale.getDefault());
nf.setMinimumFractionDigits(MIN_SIG_FIG);
return nf;
}
To quote Bjarne Stroustrup:"The >> operator is intended for formatted input; that is, reading objects of an expected type and format. Where this is not desirable and we want to read charactes as characters and then examine them, we use the get() functions."
char c;
while (input.get(c))
{
// do something with c
}
This has been answered for a long time, but I need default values frequently and prefer not to put them in the database. I create a DefaultValues
concern:
module DefaultValues
extend ActiveSupport::Concern
class_methods do
def defaults(attr, to: nil, on: :initialize)
method_name = "set_default_#{attr}"
send "after_#{on}", method_name.to_sym
define_method(method_name) do
if send(attr)
send(attr)
else
value = to.is_a?(Proc) ? to.call : to
send("#{attr}=", value)
end
end
private method_name
end
end
end
And then use it in my models like so:
class Widget < ApplicationRecord
include DefaultValues
defaults :category, to: 'uncategorized'
defaults :token, to: -> { SecureRandom.uuid }
end
Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec
Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec
, as I have ~/bin
in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...
Launch it from the root of your project, where you can see src and target dirs.
The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)
$ mvnexec
1) org.jmeld.ui.JMeldComponent
2) org.jmeld.ui.text.FileDocument
3) org.jmeld.JMeld
4) org.jmeld.util.UIDefaultsPrint
5) org.jmeld.util.PrintProperties
6) org.jmeld.util.file.DirectoryDiff
7) org.jmeld.util.file.VersionControlDiff
8) org.jmeld.vc.svn.InfoCmd
9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#?
If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P
)
By default it compiles project every run. but you can avoid that using mvnexec -B
It allows to search only in test classes -M
or --no-main
, or only in main classes -T
or --no-test
. also has a filter by name option -f <whatever>
Hope this could save you some time, for me it does.
And even simpler using IN:
SELECT ads.*, location.county
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)
In Java 8 :
int[] arr = {1,2,3};
IntStream.of(arr).boxed().collect(Collectors.toList());
Giving access to the IIS AppPool\YourAppPoolName user may be not enough with IIS default configurations.
In my case, I still had the error HTTP Error 401.3 - Unauthorized after adding the AppPool user and it was fixed only after adding permissions to the IUSR user.
This is necessary because, by default, Anonymous access is done using the IUSR. You can set another specific user, the Application Pool or continue using the IUSR, but don't forget to set the appropriate permissions.
Credits to this answer: HTTP Error 401.3 - Unauthorized
Analogous to @Resh32, but without the need to use the USE
statement:
SELECT TABLE_NAME,
COLUMN_NAME,
CONSTRAINT_NAME,
REFERENCED_TABLE_NAME,
REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "database_name"
AND TABLE_NAME = "table_name"
AND REFERENCED_COLUMN_NAME IS NOT NULL;
Useful, e.g. using the ORM.
For the OP's command:
select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0, Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from #tmp_CTF**
I get this error:
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.
when debugging something like this split the long line up so you'll get a better row number:
select compid
,2
, convert(datetime
, '01/01/'
+ CONVERT(char(4)
,cal_yr)
,101)
,0
, Update_dt
, th1
, th2
, th3_pc
, Update_id
, Update_dt
,1
from #tmp_CTF**
this now results in:
Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.
which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:
from [#tmp_CTF**]
if that is the table name.
you can try this... ALTER TABLE Your_Table ADD table_ID int NOT NULL PRIMARY KEY auto_increment;
If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.
But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.
std::pair already has the required comparison operators, which perform lexicographical comparisons using both elements of each pair. To use this, you just have to provide the comparison operators for types for types K
and V
.
Also bear in mind that std::sort
requires a strict weak ordeing comparison, and <=
does not satisfy that. You would need, for example, a less-than comparison <
for K
and V
. With that in place, all you need is
std::vector<pair<K,V>> items;
std::sort(items.begin(), items.end());
If you really need to provide your own comparison function, then you need something along the lines of
template <typename K, typename V>
bool comparePairs(const std::pair<K,V>& lhs, const std::pair<K,V>& rhs)
{
return lhs.first < rhs.first;
}
It hasn't been relevant for at least 15 years as optimizers make better decisions about this than you can. Even when it was relevant, it made a lot more sense on a CPU architecture with a lot of registers, like SPARC or M68000 than it did on Intel with its paucity of registers, most of which are reserved by the compiler for its own purposes.
Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.
First, your IntentFilter must contain an event.
static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);
Second, when you send a broadcast, use this same action:
Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);
Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.
Fourth, is your service declared in the AndroidManifest.xml?
I had the same problem. So here is what i did
And it worked.
Since everyone else already gave the answer, I'll add a bit of additional context. % the "modulus" operator is actually performing the remainder operation. The difference between mod and rem is subtle, but important.
(-1 mod 2) would normally give 1. More specifically given two integers, X and Y, the operation (X mod Y) tends to return a value in the range [0, Y). Said differently, the modulus of X and Y is always greater than or equal to zero, and less than Y.
Performing the same operation with the "%" or rem operator maintains the sign of the X value. If X is negative you get a result in the range (-Y, 0]. If X is positive you get a result in the range [0, Y).
Often this subtle distinction doesn't matter. Going back to your code question, though, there are multiple ways of solving for "evenness".
The first approach is good for beginners, because it is especially verbose.
// Option 1: Clearest way for beginners
boolean isEven;
if ((a % 2) == 0)
{
isEven = true
}
else
{
isEven = false
}
The second approach takes better advantage of the language, and leads to more succinct code. (Don't forget that the == operator returns a boolean.)
// Option 2: Clear, succinct, code
boolean isEven = ((a % 2) == 0);
The third approach is here for completeness, and uses the ternary operator. Although the ternary operator is often very useful, in this case I consider the second approach superior.
// Option 3: Ternary operator
boolean isEven = ((a % 2) == 0) ? true : false;
The fourth and final approach is to use knowledge of the binary representation of integers. If the least significant bit is 0 then the number is even. This can be checked using the bitwise-and operator (&). While this approach is the fastest (you are doing simple bit masking instead of division), it is perhaps a little advanced/complicated for a beginner.
// Option 4: Bitwise-and
boolean isEven = ((a & 1) == 0);
Here I used the bitwise-and operator, and represented it in the succinct form shown in option 2. Rewriting it in Option 1's form (and alternatively Option 3's) is left as an exercise to the reader. ;)
Hope that helps.

In the <tomcat-home>\conf\catalina.properties
file, add this new line:
spring.profiles.active=dev
This is the best practice. This way you will get the variables from GET method as well as POST method
public function index(Request $request) {
$data=$request->all();
dd($data);
}
//OR if you want few of them then
public function index(Request $request) {
$data=$request->only('id','name','etc');
dd($data);
}
//OR if you want all except few then
public function index(Request $request) {
$data=$request->except('__token');
dd($data);
}
Simply change 'Search String'
to whatever you seek and 'Replace String'
with whatever you want to replace it with.

@Jon Skeet Nice explanation. IMO if some one wants to call super.super method then one must be want to ignore the behavior of immediate parent, but want to access the grand parent behavior. This can be achieved through instance Of. As below code
public class A {
protected void printClass() {
System.out.println("In A Class");
}
}
public class B extends A {
@Override
protected void printClass() {
if (!(this instanceof C)) {
System.out.println("In B Class");
}
super.printClass();
}
}
public class C extends B {
@Override
protected void printClass() {
System.out.println("In C Class");
super.printClass();
}
}
Here is driver class,
public class Driver {
public static void main(String[] args) {
C c = new C();
c.printClass();
}
}
Output of this will be
In C Class
In A Class
Class B printClass behavior will be ignored in this case. I am not sure about is this a ideal or good practice to achieve super.super, but still it is working.
In SQL Server 2012+, you can use datefromparts()
:
select datefromparts(@year, @month, @day)
In earlier versions, you can cast a string. Here is one method:
select cast(cast(@year*10000 + @month*100 + @day as varchar(255)) as date)
Most of the answers here involves configuring, actually just by adding sftp://
on your host (see below image) you can instantly fixed that kind of problem, works for me.
And also take note that if you follow Vaggelis guide you are lowering your security, sftp
is better than using plain ftp
.
I just changed the encryption from "Use explicit FTP over TLS if available" to "Only use plain FTP" (insecure) at site manager and it works!
Try to avoid using a Mac/PC that has only 8 GB of RAM when doing Android development. As soon as you launch even 1 emulator (Genymotion or otherwise), your build times become extremely slow in Android Studio with gradle builds. This happens even if you make a simple one-line change to 1 source file.
Closing the emulator and using a real device helps a lot, but of course this is very limiting and less flexible. Reducing the RAM usage setting of the emulator can help, but the best way is to ensure your laptop has at least 12-16 GB of RAM.
Update (June 2017): There are now several good medium.com articles that explain how to speed up Android Studio gradle builds in detail, and it even works on 8 GB machines:
The summarised consensus is:
Create a gradle.properties file (either global at ~/.gradle/gradle.properties
or local to project), and add the following lines:
org.gradle.daemon=true
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
org.gradle.parallel=true
org.gradle.configureondemand=true
I resolved this error today when it occurred trying to Commit to SVN. The error was genuine, TortoiseSVN could not access a file which I tried to Commit. This file had been saved while running a program "As Administrator" in Windows. This means the file has Administrator access but not access from my account (TortoiseSVN running as interactive user). I took ownership of the nominated file under my windows account and after that Cleanup was able to proceed.
To update TechDo's answer for SQL server 2012. You need to change: 'FROM ' + @TableName + ' (NOLOCK) '
to FROM ' + @TableName + 'WITH (NOLOCK) ' +
Other wise you will get the following error: Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.

For security code, please don't generate your tokens this way: $token = md5(uniqid(rand(), TRUE));
rand()
is predictableuniqid()
only adds up to 29 bits of entropymd5()
doesn't add entropy, it just mixes it deterministicallyTry this out:
session_start();
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
$token = $_SESSION['token'];
Sidenote: One of my employer's open source projects is an initiative to backport random_bytes()
and random_int()
into PHP 5 projects. It's MIT licensed and available on Github and Composer as paragonie/random_compat.
session_start();
if (empty($_SESSION['token'])) {
if (function_exists('mcrypt_create_iv')) {
$_SESSION['token'] = bin2hex(mcrypt_create_iv(32, MCRYPT_DEV_URANDOM));
} else {
$_SESSION['token'] = bin2hex(openssl_random_pseudo_bytes(32));
}
}
$token = $_SESSION['token'];
Don't just use ==
or even ===
, use hash_equals()
(PHP 5.6+ only, but available to earlier versions with the hash-compat library).
if (!empty($_POST['token'])) {
if (hash_equals($_SESSION['token'], $_POST['token'])) {
// Proceed to process the form data
} else {
// Log this as a warning and keep an eye on these attempts
}
}
You can further restrict tokens to only be available for a particular form by using hash_hmac()
. HMAC is a particular keyed hash function that is safe to use, even with weaker hash functions (e.g. MD5). However, I recommend using the SHA-2 family of hash functions instead.
First, generate a second token for use as an HMAC key, then use logic like this to render it:
<input type="hidden" name="token" value="<?php
echo hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
?>" />
And then using a congruent operation when verifying the token:
$calc = hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
if (hash_equals($calc, $_POST['token'])) {
// Continue...
}
The tokens generated for one form cannot be reused in another context without knowing $_SESSION['second_token']
. It is important that you use a separate token as an HMAC key than the one you just drop on the page.
Anyone who uses the Twig templating engine can benefit from a simplified dual strategy by adding this filter to their Twig environment:
$twigEnv->addFunction(
new \Twig_SimpleFunction(
'form_token',
function($lock_to = null) {
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
if (empty($_SESSION['token2'])) {
$_SESSION['token2'] = random_bytes(32);
}
if (empty($lock_to)) {
return $_SESSION['token'];
}
return hash_hmac('sha256', $lock_to, $_SESSION['token2']);
}
)
);
With this Twig function, you can use both the general purpose tokens like so:
<input type="hidden" name="token" value="{{ form_token() }}" />
Or the locked down variant:
<input type="hidden" name="token" value="{{ form_token('/my_form.php') }}" />
Twig is only concerned with template rendering; you still must validate the tokens properly. In my opinion, the Twig strategy offers greater flexibility and simplicity, while maintaining the possibility for maximum security.
If you have a security requirement that each CSRF token is allowed to be usable exactly once, the simplest strategy regenerate it after each successful validation. However, doing so will invalidate every previous token which doesn't mix well with people who browse multiple tabs at once.
Paragon Initiative Enterprises maintains an Anti-CSRF library for these corner cases. It works with one-use per-form tokens, exclusively. When enough tokens are stored in the session data (default configuration: 65535), it will cycle out the oldest unredeemed tokens first.
> grepl("^[^_]+_1",s)
[1] FALSE
> grepl("^[^_]+_2",s)
[1] TRUE
basically, look for everything at the beginning except _
, and then the _2
.
+1 to @Ananda_Mahto for suggesting grepl
instead of grep
.
I had the same problem as Christer Fernstrom. In my case it was a message I had put in my .bashrc that reminds me do do a backup when I haven't done one in a couple of days.
Yeah you can't access your drive folder from you android phone or emulator because your computer and android are two different OS.I would go for res folder of android because it has good resources management methods. Until and unless you have very good reason to put you file in assets folder. Instead You can do this
try {
Resources res = getResources();
InputStream in_s = res.openRawResource(R.raw.yourfile);
byte[] b = new byte[in_s.available()];
in_s.read(b);
String str = new String(b);
} catch (Exception e) {
Log.e(LOG_TAG, "File Reading Error", e);
}
Managed to do it:
b = pd.read_csv('b.dat')
b.index = pd.to_datetime(b['date'],format='%m/%d/%y %I:%M%p')
b.groupby(by=[b.index.month, b.index.year])
Or
b.groupby(pd.Grouper(freq='M')) # update for v0.21+
Another programmatically approach;
final Button btn = (Button) findViewById(R.id.btnSize);
final float[] size = {12};
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
size[0] +=2;
btn.setTextSize(size[0] +2);
}
});
Every time you click your button, Button text will be change (+2px size). You can add another button and change size -2px too. If you want to save size for another openings, you may use Shared Preference interface.
Both ways are supported for a reason: there are times when one is more appropriate than the other.
import module
: nice when you are using many bits from the module. drawback is that you'll need to qualify each reference with the module name.
from module import ...
: nice that imported items are usable directly without module name prefix. The drawback is that you must list each thing you use, and that it's not clear in code where something came from.
Which to use depends on which makes the code clear and readable, and has more than a little to do with personal preference. I lean toward import module
generally because in the code it's very clear where an object or function came from. I use from module import ...
when I'm using some object/function a lot in the code.
In my case a has to add my classes, when building the SessionFactory
, with addAnnotationClass
Configuration configuration.configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration
.addAnnotatedClass(MyEntity1.class)
.addAnnotatedClass(MyEntity2.class)
.buildSessionFactory(builder.build());
Maybe in case there are scheduled alarms and uncleared app icon badges.
NSArray *scheduledLocalNotifications = [application scheduledLocalNotifications];
NSInteger applicationIconBadgeNumber = [application applicationIconBadgeNumber];
[application cancelAllLocalNotifications];
[application setApplicationIconBadgeNumber:0];
for (UILocalNotification* scheduledLocalNotification in scheduledLocalNotifications) {
[application scheduleLocalNotification:scheduledLocalNotification];
}
[application setApplicationIconBadgeNumber:applicationIconBadgeNumber];
