I am not sure what you really want here. If you want to see the .NET framework source code, you may try Netmassdownloader. It's free.
If you want to see any assembly's code (not just .NET), you can use ReSharper. Although it's not free.
From the DotNetZip help file, http://dotnetzip.codeplex.com/releases/
using (ZipFile zip = new ZipFile())
{
zip.UseUnicodeAsNecessary= true; // utf-8
zip.AddDirectory(@"MyDocuments\ProjectX");
zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G") ;
zip.Save(pathToSaveZipFile);
}
For VS 2013, .NET Framework 4.5.1 also has a AccessViolationException
bug (KB2915689) when dealing with SQL Server / TCP Sockets. Upgrading to .NET Framework 4.5.2 corrects this problem.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
You can do this easily with a matplotlib AxisDivider.
The example from the linked page also works without using subplots:
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np
plt.figure()
ax = plt.gca()
im = ax.imshow(np.arange(100).reshape((10,10)))
# create an axes on the right side of ax. The width of cax will be 5%
# of ax and the padding between cax and ax will be fixed at 0.05 inch.
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
plt.colorbar(im, cax=cax)
There's one big difference between CLOCK_REALTIME and MONOTONIC. CLOCK_REALTIME can jump forward or backward according to NTP. By default, NTP allows the clock rate to be speeded up or slowed down by up to 0.05%, but NTP cannot cause the monotonic clock to jump forward or backward.
The other advice here didn't help me, but I fixed this error by going to Product > Scheme > Edit Scheme
. Then I clicked Build
on the left hand side and deselected any checkboxes next to AppNameTests
. I'm using XCode 6.3
Start -> shift + command Prompt right click will helps to use as another user or as Admin
Have you thought about creating a view with 'Folder = Show all items without folders', that would get all your documents out of their folders and then perhaps you could create your filter(s) over that view.

I have used react-native-image-picker
to select photo. In my case after choosing the photp from mobile. I'm storing it's info in component state
. After, I'm sending POST
request using fetch
like below
const profile_pic = {
name: this.state.formData.profile_pic.fileName,
type: this.state.formData.profile_pic.type,
path: this.state.formData.profile_pic.path,
uri: this.state.formData.profile_pic.uri,
}
const formData = new FormData()
formData.append('first_name', this.state.formData.first_name);
formData.append('last_name', this.state.formData.last_name);
formData.append('profile_pic', profile_pic);
const Token = 'secret'
fetch('http://10.0.2.2:8000/api/profile/', {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "multipart/form-data",
Authorization: `Token ${Token}`
},
body: formData
})
.then(response => console.log(response.json()))
<!-- One simple solution to your problem could be like this: -->
<div>
<input type="text" id="fname" onmousemove="javascript: alert(this.id);" />
<!-- OR -->
<input type="text" id="fname" onclick="javascript: alert(this.id);" />
</div>
<!-- Both mousemove over the field & click on the field displays "fname"-->
<!-- Works fantastic in IE, FireFox, Chrome, Opera. -->
<!-- I didn't test it for Safari. -->
Here is another one if you need window resize event:
class DivSize extends React.Component {
constructor(props) {
super(props)
this.state = {
width: 0,
height: 0
}
this.resizeHandler = this.resizeHandler.bind(this);
}
resizeHandler() {
const width = this.divElement.clientWidth;
const height = this.divElement.clientHeight;
this.setState({ width, height });
}
componentDidMount() {
this.resizeHandler();
window.addEventListener('resize', this.resizeHandler);
}
componentWillUnmount(){
window.removeEventListener('resize', this.resizeHandler);
}
render() {
return (
<div
className="test"
ref={ (divElement) => { this.divElement = divElement } }
>
Size: widht: <b>{this.state.width}px</b>, height: <b>{this.state.height}px</b>
</div>
)
}
}
ReactDOM.render(<DivSize />, document.querySelector('#container'))
Use the -O file
option.
E.g.
wget google.com

wget -O foo.html google.com
...

There is also Mappa - http://mappatool.com/.
It only supports polygons, but they are definitely the hardest parts :)
I hope following code fragment would help you.
- (void)handleZoomOutAction:(id)sender {
MKCoordinateRegion newRegion=MKCoordinateRegionMake(mapView.region.center,MKCoordinateSpanMake(mapView.region.s pan.latitudeDelta/0.5, mapView.region.span.longitudeDelta/0.5));
[mapView setRegion:newRegion];
}
- (void)handleZoomInAction:(id)sender {
MKCoordinateRegion newRegion=MKCoordinateRegionMake(mapView.region.center,MKCoordinateSpanMake(mapView.region.span.latitudeDelta*0.5, mapView.region.span.longitudeDelta*0.5));
[mapView setRegion:newRegion];
}
You can choose any value in stead of 0.5 to reduce or increase zoom level. I have used these methods on click of two buttons.

This problem arise basically when you save your python code in a UTF-8 or UTF-16 encoding because python add some special character at the beginning of the code automatically (which is not shown by the text editors) to identify the encoding format. But, when you try to execute the code it gives you the syntax error in line 1 i.e, start of code because python compiler understands ASCII encoding. when you view the code of file using read() function you can see at the begin of the returned code '\ufeff' is shown. The one simplest solution to this problem is just by changing the encoding back to ASCII encoding(for this you can copy your code to a notepad and save it Remember! choose the ASCII encoding... Hope this will help.
I was able to figure it out. In case someone wants to know below the code that worked for me:
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);
Let me know if there is a simpler way o doing it.
git pull origin master
will fetch all the changes from the remote's master branch and will merge it into your local.We generally don't use git pull origin/master.We can do the same thing by git merge origin/master
.It will merge all the changes from "cached copy" of origin's master branch into your local branch.In my case git pull origin/master
is throwing the error.
File sdcard = Environment.getExternalStorageDirectory();
File f=new File(sdcard+"/dor");
f.mkdir();
this will create a folder named dor in your sdcard. then to fetch file for eg- filename.json which is manually inserted in dor folder. Like:
File file1 = new File(sdcard,"/dor/fitness.json");
.......
.....
< uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and don't forget to add code in manifest
If it's only a tuple of tuples, something like rows=[map(int, row) for row in rows]
will do the trick. (There's a list comprehension and a call to map(f, lst), which is equal to [f(a) for a in lst], in there.)
Eval is not what you want to do, in case there's something like __import__("os").unlink("importantsystemfile")
in your database for some reason.
Always validate your input (if with nothing else, the exception int() will raise if you have bad input).

I had the same issue and while user1732055's answer fixes the border, it removes the dropdown arrows. I solved this by removing the border from the select
element and creating a wrapper span
which has a border.
html:
<span class="select-wrapper">
<select class="form-control no-radius">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</span>
css:
select.no-radius{
border:none;
}
.select-wrapper{
border: 1px solid black;
border-radius: 0px;
}
Visual studio community edition is bundled with xamarin and which is free as well.
Make sure you append the file name after the path name (path\fileName.extension). I spent more than one hour without note this.
As @borayeris said,
yum install glibc.i686
But if you cannot find glibc.i686 or libstdc++ package, try -
sudo yum search glibc
sudo yum search libstd
and then,
sudo yum install {package}
As has been mentioned, as of PHP 5.6+ you can (should!) use the ...
token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:
<?php
function variadic($arg1, $arg2)
{
// Do stuff
echo $arg1.' '.$arg2;
}
$array = ['Hello', 'World'];
// 'Splat' the $array in the function call
variadic(...$array);
// 'Hello World'
Note: array items are mapped to arguments by their position in the array, not their keys.
As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array
.
Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.
(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)
This is great for making sure an array contains items of a specific type:
<?php
// Define the function...
function variadic($var, SomeClass ...$items)
{
// $items will be an array of objects of type `SomeClass`
}
// Then you can call...
variadic('Hello', new SomeClass, new SomeClass);
// or even splat both ways
$items = [
new SomeClass,
new SomeClass,
];
variadic('Hello', ...$items);
Here is working solution:

If your SQL Server version supports the function FORMAT you could do it like this:
select format(getdate(), 'yyyy-MM-dd HH:mm:ss.fff')
If you use XHTML, for some reason, note that XHTML 1.0 C 4 says: “Use external scripts if your script uses < or & or ]]> or --.” That is, don’t embed script code inside a script
element but put it into a separate JavaScript file and refer to it with <script src="foo.js"></script>
.
Either make your friends download the runtime DLL (@Kay's answer), or compile the app with static linking.
In visual studio, go to Project tab -> properties - > configuration properties -> C/C++ -> Code Generation
on runtime library choose /MTd
for debug mode and /MT
for release mode.
This will cause the compiler to embed the runtime into the app. The executable will be significantly bigger, but it will run without any need of runtime dlls.
Consider Moshi's JsonWriter class (source). It has a wonderful API and it reduces copying to a minimum, everything is nicely streamed to the OutputStream.
OutputStream os = ...;
JsonWriter json = new JsonWriter(Okio.sink(os));

.name("id").value(userID)
.name("type").value(methodn)
...
.endObject();
To install all currently supported python versions (python 3.6 is already pre-installed) including pip for Ubuntu 18.04 do the following:
To install python3.5 and python3.7, use the deadsnakes ppa:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.5
sudo apt-get install python3.7
Install python2.7 via distribution packages:
sudo apt install python-minimal # on Ubuntu 18.04 python-minimal maps to python2.7
To install pip use:
sudo apt install python-pip # on Ubuntu 18.04 this refers to pip for python2.7
sudo apt install python3-pip # on Ubuntu 18.04 this refers to pip for python3.6
python3.5 -m pip install pip # this will install pip only for the current user
python3.7 -m pip install pip
I used it for setting up a CI-chain for a python project with tox and Jenkins.
It's an old trick, but I still find the easiest way to do this is to use outline-offset with a negative value (example below uses -6px). Here's a fiddle of it—I've made the outer border red and the outline white to differentiate the two:
.outline-offset {
width:300px;
height:200px;
background:#333c4b;
border:2px solid red;
outline:2px #fff solid;
outline-offset:-6px;
}
<div class="outline-offset"></div>
I would reconsider trying to find out if a file exists. Instead, you should try to open it (in Standard C or C++) in the same mode you intend to use it. What use is knowing that the file exists if, say, it isn't writable when you need to use it?
Just came across this question as it was linked in a recent question on SO.
Shameless plug of an answer: Use cSplit
from my "splitstackshape" package:
df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
library(splitstackshape)
cSplit(df, "FOO", "|")
# ID FOO_1 FOO_2
# 1 11 a b
# 2 12 b c
# 3 13 x y
This particular function also handles splitting multiple columns, even if each column has a different delimiter:
df <- data.frame(ID=11:13,
FOO=c('a|b','b|c','x|y'),
BAR = c("A*B", "B*C", "C*D"))
cSplit(df, c("FOO", "BAR"), c("|", "*"))
# ID FOO_1 FOO_2 BAR_1 BAR_2
# 1 11 a b A B
# 2 12 b c B C
# 3 13 x y C D
Essentially, it's a fancy convenience wrapper for using A base R approach could be:read.table(text = some_character_vector, sep = some_sep)
and binding that output to the original data.frame
. In other words, another
df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
cbind(df, read.table(text = as.character(df$FOO), sep = "|"))
ID FOO V1 V2
1 11 a|b a b
2 12 b|c b c
3 13 x|y x y
Open is an access level, was introduced to impose limitations on class inheritance on Swift.
This means that the open access level can only be applied to classes and class members.
In Classes
An open class can be subclassed in the module it is defined in and in modules that import the module in which the class is defined.
In Class members
The same applies to class members. An open method can be overridden by subclasses in the module it is defined in and in modules that import the module in which the method is defined.
THE NEED FOR THIS UPDATE
Some classes of libraries and frameworks are not designed to be subclassed and doing so may result in unexpected behavior. Native Apple library also won't allow overriding the same methods and classes,
So after this addition they will apply public and private access levels accordingly.
For more details have look at Apple Documentation on Access Control
Set the Screen orientation to portrait in Manifest file under the activity Tag.

You can wrap them in a div and give the div a set width (the width of the widest image + margin maybe?) and then float the divs. Then, set the images to the center of their containing divs. Your margins between images won't be consistent for the differently sized images but it'll lay out much more nicely on the page.
A lot of problems can be avoided by only creating a branch
to work on & not working on master
:
git checkout -b mybranch
The following works for remote
commits already pushed & a mixture of remote
pushed commits / local
only commits:
# example merging 4 commits
git checkout mybranch
git rebase -i mybranch~4 mybranch
# at the interactive screen
# choose fixup for commit: 2 / 3 / 4
git push -u origin +mybranch
I also have some pull request notes which may be helpful.
Use Projections to specify which columns you would like to return.
Example
SQL Query
SELECT user.id, user.name FROM user;
Hibernate Alternative
Criteria cr = session.createCriteria(User.class)
.setProjection(Projections.projectionList()
.add(Projections.property("id"), "id")
.add(Projections.property("Name"), "Name"))
.setResultTransformer(Transformers.aliasToBean(User.class));
List<User> list = cr.list();
I once had the same problem, and then I searched and found this and it worked for me:
I had got some of the boxes unchecked, so I checked them again, then it worked. Just go to
Windows > Preferences > Java > Editor > Content Assist > Advanced
and check the boxes which you want .
Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.
To add the jar file to your project in Eclipse, do the following:
If you want to set title in Java file, then write in your activity onCreate
setTitle("Your Title");
if you want to in Manifest then write
<activity
android:name=".MainActivity"
android:label="Your Title" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
like this :
df.groupby('colour').size().plot(kind='bar')
Latest update:
Html.fromHtml(string);
//deprecated after Android N versions..
Following code give support to android N and above versions...
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setText(Html.fromHtml(yourHtmlString,Html.FROM_HTML_MODE_LEGACY));
}
else
{
textView.setText(Html.fromHtml(yourHtmlString));
}
a very common try_files line which can be applied on your condition is
location / {
try_files $uri $uri/ /test/index.html;
}
you probably understand the first part, location /
matches all locations, unless it's matched by a more specific location, like location /test
for example
The second part ( the try_files
) means when you receive a URI that's matched by this block try $uri
first, for example http://example.com/images/image.jpg
nginx will try to check if there's a file inside /images
called image.jpg
if found it will serve it first.
Second condition is $uri/
which means if you didn't find the first condition $uri
try the URI as a directory, for example http://example.com/images/
, ngixn will first check if a file called images
exists then it wont find it, then goes to second check $uri/
and see if there's a directory called images
exists then it will try serving it.
Side note: if you don't have autoindex on
you'll probably get a 403 forbidden error, because directory listing is forbidden by default.
EDIT: I forgot to mention that if you have
index
defined, nginx will try to check if the index exists inside this folder before trying directory listing.
Third condition /test/index.html
is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html
inside the folder test
and serve it if it exists.
If the third condition fails too, then nginx will serve the 404 error page.
Also there's something called named locations, like this
location @error {
}
You can call it with try_files
like this
try_files $uri $uri/ @error;
TIP: If you only have 1 condition you want to serve, like for example inside folder images
you only want to either serve the image or go to 404 error, you can write a line like this
location /images {
try_files $uri =404;
}
which means either serve the file or serve a 404 error, you can't use only $uri
by it self without =404
because you need to have a fallback option.
You can also choose which ever error code you want, like for example:
location /images {
try_files $uri =403;
}
This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..
For checkboxes there is actually a built-in solution in the form of UITableViewCell accessories. You can set up your form as a UITableView in which each cell as a selectable option and use accessoryType
to set a check mark for selected items.
Here is a pseudo-code example:
let items = [SelectableItem]
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Get the item for the current row
let item = self.items[indexPath.row]
// ...dequeue and set up the `cell` as you wish...
// Use accessoryType property to mark the row as checked or not...
cell.accessoryType = item.selected ? .checkmark : .none
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// Unselect row
tableView.deselectRow(at: indexPath, animated: false)
// Toggle selection
let item = self.items[indexPath.row]
item.selected = !item.selected
tableView.reloadData()
}
Radio buttons however do require a custom implementation, see the other answers.
You are inside a namespace
so you should use \Exception
to specify the global namespace:
try {
$this->buildXMLHeader();
} catch (\Exception $e) {
return $e->getMessage();
}
In your code you've used catch (Exception $e)
so Exception
is being searched in/as:
App\Services\PayUService\Exception
Since there is no Exception
class inside App\Services\PayUService
so it's not being triggered. Alternatively, you can use a use
statement at the top of your class like use Exception;
and then you can use catch (Exception $e)
.
In the context of Drupal, the difference will depend whether clean URLs are on or not.
With them off, $_SERVER['REQUEST_URI']
will have the full path of the page as called w/ /index.php
, while $_GET["q"]
will just have what is assigned to q
.
With them on, they will be nearly identical w/o other arguments, but $_GET["q"]
will be missing the leading /
. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.
The Instrumentation class has a getObjectSize() method however, you shouldn't need to use it at runtime. The easiest way to examine memory usage is to use a profiler which is designed to help you track memory usage.
numpy.append
is pretty different from list.append in python. I know that's thrown off a few programers new to numpy. numpy.append
is more like concatenate, it makes a new array and fills it with the values from the old array and the new value(s) to be appended. For example:
import numpy
old = numpy.array([1, 2, 3, 4])
new = numpy.append(old, 5)
print old
# [1, 2, 3, 4]
print new
# [1, 2, 3, 4, 5]
new = numpy.append(new, [6, 7])
print new
# [1, 2, 3, 4, 5, 6, 7]
I think you might be able to achieve your goal by doing something like:
result = numpy.zeros((10,))
result[0:2] = [1, 2]
# Or
result = numpy.zeros((10, 2))
result[0, :] = [1, 2]
Update:
If you need to create a numpy array using loop, and you don't know ahead of time what the final size of the array will be, you can do something like:
import numpy as np
a = np.array([0., 1.])
b = np.array([2., 3.])
temp = []
while True:
rnd = random.randint(0, 100)
if rnd > 50:
temp.append(a)
else:
temp.append(b)
if rnd == 0:
break
result = np.array(temp)
In my example result will be an (N, 2) array, where N is the number of times the loop ran, but obviously you can adjust it to your needs.
new update
The error you're seeing has nothing to do with types, it has to do with the shape of the numpy arrays you're trying to concatenate. If you do np.append(a, b)
the shapes of a
and b
need to match. If you append an (2, n) and (n,) you'll get a (3, n) array. Your code is trying to append a (1, 0) to a (2,). Those shapes don't match so you get an error.

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.
You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.
Here is my solution:
<div class="form-group row">
<div class="col-xs-8">
<label class="control-label">My Label</label>
<div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
<input class="form-control" type="text" readonly="" value="12-02-2012">
<span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</div>
</div>
CSS changes in datepicker.css on lines 176-177:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 34:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;
UPDATE
Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:
CSS changes in datepicker.css on lines 446-447:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 46:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;
Finally, the JavaScript to enable the datepicker (with some options):
$(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });
Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.
It isn't giving any errors?
Try
SET @tmpType = 'premium
'
and
SET @tmpType = 'basic'
You can check out libvideo. It's much more up-to-date than YoutubeExtractor, and is fast and clean to use.
For iOS 10+, you can use this method for knowing when your notification is clicked irrespective of the state of the app.
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
//Notification clicked
completionHandler()
}
It looks like the limit has changed. You can store 5TB for a single object.
The total volume of data and number of objects you can store are unlimited. Individual Amazon S3 objects can range in size from a minimum of 0 bytes to a maximum of 5 terabytes. The largest object that can be uploaded in a single PUT is 5 gigabytes. For objects larger than 100 megabytes, customers should consider using the Multipart Upload capability.
If you are using JQuery with Form plugin, you can use:
$('#myForm').ajaxSubmit({
headers: {
"foo": "bar"
}
});
You could use the below to take multiple inputs separated by a keyword
a,b,c=raw_input("Please enter the age of 3 people in one line using commas\n").split(',')
I had the same issue as OP but none of the current answers solved my issue so to add a slightly different answer that did work for me:
Running Python 3.6.5 on a Windows Machine, I used the format
r"\DriveName\then\file\path\txt.md"
so the combination of double backslashes from reading @Johnsyweb UNC link and adding the r in front as recommended solved my similar to OP's issue.
Just a warning to the correct answers above:
Using the -f / --force Method provides a risk to lose the file if you mix up source and target:
mbucher@server2:~/test$ ls -la

lrwxrwxrwx 1 mbucher www-data 11 May 25 15:26 thesymlink -> data.tar.gz
Of course this is intended, but usually mistakes occur. So, deleting and rebuilding the symlink is a bit more work but also a bit saver:
mbucher@server2:~/test$ rm thesymlink && ln -s thesymlink otherdata.tar.gz
ln: creating symbolic link `otherdata.tar.gz': File exists
which at least keeps my file.
Both are the same, both are a term which means to encapsulate some code into a unit of work which can be called from elsewhere.
Historically, there may have been a subtle difference with a "method" being something which does not return a value, and a "function" one which does. in C# that would translate as:
public void DoSomething() {} // method
public int DoSomethingAndReturnMeANumber(){} // function
But really, I re-iterate that there is really no difference in the 2 concepts.
The problem is, os.path.join
doesn't take a list
as argument, it has to be separate arguments.
This is where *
, the 'splat' operator comes into play...
I can do
>>> s = "c:/,home,foo,bar,some.txt".split(",")
>>> os.path.join(*s)
'c:/home\\foo\\bar\\some.txt'
The Google Play Store doesn't provide this data, so the sites must just be scraping it.
As pierre said, there is no way to have a user interface for a windows service (or no easy way). What I do in that kind of situation is to have a settings file that is read from the service on whatever interval the service operates on and have a standalone application that makes changes to the settings file.
Here is your code. I'm assuming you're using python 3 based on the your use of print()
and input()
:
import random
def main():
#random.seed() --> don't need random.seed()
#Prompts the user to enter the number of tickets they wish to play.
#python 3 version:
tickets = int(input("How many lottery tickets do you want?\n"))
#Creates the dictionaries "winning_numbers" and "guess." Also creates the variable "winnings" for total amount of money won.
winning_numbers = []
winnings = 0
#Generates the winning lotto numbers.
for i in range(tickets * 5):
#del winning_numbers[:] what is this line for?
randNum = random.randint(1,30)
while randNum in winning_numbers:
randNum = random.randint(1,30)
winning_numbers.append(randNum)
print(winning_numbers)
guess = getguess(tickets)
nummatches = checkmatch(winning_numbers, guess)
print("Ticket #"+str(i+1)+": The winning combination was",winning_numbers,".You matched",nummatches,"number(s).\n")
winningRanks = [0, 0, 10, 500, 20000, 1000000]
winnings = sum(winningRanks[:nummatches + 1])
print("You won a total of",winnings,"with",tickets,"tickets.\n")
#Gets the guess from the user.
def getguess(tickets):
guess = []
for i in range(tickets):
bubble = [int(i) for i in input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split()]
guess.extend(bubble)
print(bubble)
return guess
#Checks the user's guesses with the winning numbers.
def checkmatch(winning_numbers, guess):
match = 0
for i in range(5):
if guess[i] == winning_numbers[i]:
match += 1
return match
main()
This can be done with something like this:
# foo.py
class Foo:
def method_1():
results = uses_some_other_method()
# testing.py
from mock import patch
@patch('Foo.uses_some_other_method', return_value="specific_value"):
def test_some_other_method(mock_some_other_method):
foo = Foo()
the_value = foo.method_1()
assert the_value == "specific_value"
Here's a source that you can read: Patching in the wrong place
This issue is based on your installed version of visual studio and Windows, you can follow the following steps:-
downgraded your PCL by the following command
Install-Package Xamarin.Forms -Version 2.5.1.527436
Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=
I think you set the marquee width related to 5 images total width. It works fine
ex: <marquee style="width:700px"></marquee>
From outside the defining class, as @Telos mentions, you can only use EventHandler on the left-hand side of a +=
or a -=
. So, if you have the ability to modify the defining class, you could provide a method to perform the check by checking if the event handler is null
- if so, then no event handler has been added. If not, then maybe and you can loop through the values in
Delegate.GetInvocationList. If one is equal to the delegate that you want to add as event handler, then you know it's there.
public bool IsEventHandlerRegistered(Delegate prospectiveHandler)
{
if ( this.EventHandler != null )
{
foreach ( Delegate existingHandler in this.EventHandler.GetInvocationList() )
{
if ( existingHandler == prospectiveHandler )
{
return true;
}
}
}
return false;
}
And this could easily be modified to become "add the handler if it's not there". If you don't have access to the innards of the class that's exposing the event, you may need to explore -=
and +=
, as suggested by @Lou Franco.
However, you may be better off reexamining the way you're commissioning and decommissioning these objects, to see if you can't find a way to track this information yourself.
Just run a git fetch
command. It will pull all the remote branches to your local repository, and then do a git branch -a
to list all the branches.
This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.
I had the same issue during building my app in AppVeyor.
c:\php
echo extension=php_openssl.dll >> c:\php\php.ini
echo curl.cainfo=c:\php\cacert.pem >> c:\php\php.ini
Perhaps not 100% answering the question, but i stumbled onto this thread in the hope of solving a session problem when ajax-posting a fileupload from the assetmanager of the innovastudio editor. Eventually the solution was simple: they have a flash-uploader. Disabling that (setting
var flashUpload = false;
in asset.php) and the lights started blinking again.
As these problems can be very hard to debug i found that putting something like the following in the upload handler will set you (well, me in this case) on the right track:
$sn=session_name();
error_log("session_name: $sn ");
if(isset($_GET[$sn])) error_log("session as GET param");
if(isset($_POST[$sn])) error_log("session as POST param");
if(isset($_COOKIE[$sn])) error_log("session as Cookie");
if(isset($PHPSESSID)) error_log("session as Global");
A dive into the log and I quickly spotted the missing session, where no cookie was sent.
Its my code
jQuery(document).ready(function(e) {

var scroll_position = jQuery('.product-bottom').offset().top;
var screen_height = jQuery(window).height();
var activation_offset = 0;
var max_scroll_height = jQuery('body').height() + screen_height;
var scroll_activation_point = scroll_position - (screen_height * activation_offset);
jQuery(window).on('scroll', function(e) {
var y_scroll_pos = window.pageYOffset;
var element_in_view = y_scroll_pos > scroll_activation_point;
var has_reached_bottom_of_page = max_scroll_height <= y_scroll_pos && !element_in_view;
if (element_in_view || has_reached_bottom_of_page) {
jQuery('.product-bottom').addClass("change");
} else {
jQuery('.product-bottom').removeClass("change");

I have created the batch file and put it to the Cygwin's /bin directory. This script was developed so it allows to install/uninstall the registry entries for opening selected folders and drives in Cygwin. For details see the link http://with-love-from-siberia.blogspot.com/2013/12/cygwin-here.html.
update: This solution does the same as early suggestions but all manipulations with Windows Registry are hidden within the script.
Perform the command to install

Perform the command to uninstall

.Essentially, remove all the Ajax facilities related to the commandButton

as form the configuration xml it is clear that you are going to use spring based transaction. Please make sure that the import which you are using for @Transactional is "org.springframework.transaction.annotation.Transactional"
in your case it might be "javax.transaction.Transactional"

I had this script in app.js in laravel which automatically adds all components in the component folder.
const files = require.context('./', true, /\.vue$/i)
files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key)))
To make it work just add default
const files = require.context('./', true, /\.vue$/i)
files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default))

Discussion of the semantics of the question is fairly nuanced (and very academic), but here's the general idea:
Duck Typing
(“If it walks like a duck and quacks like a duck then it is a duck.”) - YES! but what does that mean??! This is best illustrated by example:
Examples of Duck Typing functionality:
Imagine I have a magic wand. It has special powers. If I wave the wand and say "Drive!" to a car, well then, it drives!
Does it work on other things? Not sure: so I try it on a truck. Wow - it drives too! I then try it on planes, trains and 1 Woods (they are a type of golf club which people use to 'drive' a golf ball). They all drive!
But would it work on say, a teacup? Error: KAAAA-BOOOOOOM! that didn't work out so good. ====> Teacups can't drive!! duh!?
This is basically the concept of duck typing. It's a try-before-you-buy system. If it works, all is well. But if it fails, like a grenade still in your hand, it's gonna blow up in your face.
In other words, we are interested in what the object can do, rather than with what the object is.
Example: statically typed languages
If we were concerned with what the object actually was, then our magic trick will work only on pre-set, authorised types - in this case cars, but will fail on other objects which can drive: trucks, mopeds, tuk-tuks etc. It won't work on trucks because our magic wand is expecting it to only work on cars.
In other words, in this scenario, the magic wand looks very closely at what the object is (is it a car?) rather than what the object can do (e.g. whether cars, trucks etc. can drive).
The only way you can get a truck to drive is if you can somehow get the magic wand to expect both trucks and cars (perhaps by "implementing a common interface"). If you don't know what that means then just ignore it for the moment.
Summary: Key take-out
What's important in duck typing is what the object can actually do, rather than what the object is.
The HTML5 history spec is quirky.
history.pushState()
doesn't dispatch a popstate
event or load a new page by itself. It was only meant to push state into history. This is an "undo" feature for single page applications. You have to manually dispatch a popstate
event or use history.go()
to navigate to the new state. The idea is that a router can listen to popstate
events and do the navigation for you.
Some things to note:
history.pushState()
and history.replaceState()
don't dispatch popstate
events.history.back()
, history.forward()
, and the browser's back and forward buttons do dispatch popstate
events.history.go()
and history.go(0)
do a full page reload and don't dispatch popstate
events.history.go(-1)
(back 1 page) and history.go(1)
(forward 1 page) do dispatch popstate
events.You can use the history API like this to push a new state AND dispatch a popstate event.
history.pushState({message:'New State!'}, 'New Title', '/link');
window.dispatchEvent(new PopStateEvent('popstate', {
bubbles: false,
cancelable: false,
state: history.state
}));
Then listen for popstate
events with a router.
Check your routing method:
if your routing state is like this
.state('app.register', {
url: '/register',
views: {
'menuContent': {
templateUrl: 'templates/register.html',
}
}
})
then you should use
$location.path("/app/register");
None of the above answers worked for me. It appears that my own app's usage of DirectoryInfo
on the target directory was causing it to remain locked.
Forcing garbage collection appeared to resolve the issue, but not right away. A few attempts to delete where required.
Note the Directory.Exists
as it can disappear after an exception. I don't know why the delete for me was delayed (Windows 7 SP1)
for (int attempts = 0; attempts < 10; attempts++)
{
try
{
if (Directory.Exists(folder))
{
Directory.Delete(folder, true);
}
return;
}
catch (IOException e)
{
GC.Collect();
Thread.Sleep(1000);
}
}
throw new Exception("Failed to remove folder.");
With an indexed array, you can to something like this:
declare -a a=()
a+=('foo' 'bar')
For anyone trying to do this using mysql workbench or sequel pro these are the inputs:

database: optional
port: optional (unless you chose another port, defaults to 3306)
ssh host: 192.168.56.101 (or ip that you choose for this vm, like above)
ssh user: vagrant (vagrants default username)
ssh password: vagrant (vagrants default password)

When an element, such as a div
is floated
, its parent container no longer considers its height, i.e.
<div id="main">
<div id="child" style="float:left;height:40px;"> Hi</div>
</div>
The parent container will not be be 40 pixels tall by default. This causes a lot of weird little quirks if you're using these containers to structure layout.
So the clearfix
class that various frameworks use fixes this problem by making the parent container "acknowledge" the contained elements.
Day to day, I normally just use frameworks such as 960gs, Twitter Bootstrap for laying out and not bothering with the exact mechanics.

The data.table
package has its IDate
class and functionalities similar to lubridate
or the zoo
package. You could do:
dt = data.table(
Name = c('Joe', 'Amy', 'John'),
JoiningDate = c('12/31/09', '10/28/09', '05/06/10'),
AmtPaid = c(1000, 100, 200)
)
require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]
A great way to check if a database exists in PHP is:
$mysql = mysql_connect("<your host>", "root", "");
if (mysql_select_db($mysql, '<your db name>')) {
echo "Database exists";
} else {
echo "Database does not exist";
}
That is the method that I always use.
I think you want to lowercase the checked value? Try:
var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();
or you want to check it, then get its value as lowercase:
var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();
If you can, swap out the ArrayList
for an ArrayDeque
, which has convenient methods like removeLast
.
wxWidgets is worth checking out. It is well supported on Ruby via wxRuby. For an example app, have a look at wxRIDE. See it compared to other toolkits. You might also want to check out Anvil, which is a sort of Rails-ish framework for working with wx. It looks moribund now, though.
Either I don't understand your question, or Enumerable#find is the thing you were looking for.
try importing the below package from random import*
In reference to the quick reference list, specifically you can use the following :
\.\ Root Directory + Current directory (Drive Letter)
It looks like you are passing an NSString
parameter where you should be passing an NSData
parameter:
NSError *jsonError;
NSData *objectData = [@"{\"2\":\"3\"}" dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
You can also use this method:
<input type="text" class="@(@mvccondition ? "true-class" : "false-class")">
Try this .. Good luck Thanks.
I should mention that if you are using Mac, downloading and running an app from the App Store (like "iBoostUp" etc.) which will clean out unused system files can speed up your computer dramatically, including AS.
I also found that adding more memory to my Mac sped up AS as well.
My solution:
long unsigned int i;
for(i = 0u; i < sizeof(integer) * CHAR_BIT; i++) {
if(integer & LONG_MIN)
printf("1");
else
printf("0");
integer <<= 1;
}
printf("\n");
No, Bootstrap does not introduce special considerations for disabling a drop-down.
<select id="xxx" name="xxx" class="input-medium" disabled>
or
<select id="xxx" name="xxx" class="input-medium" disabled="disabled">
will work. I prefer to give attributes values (as in the second form; in XHTML, attributes must have a value), but the HTML spec says:
The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.
The key differences between read-only and disabled:*
The Disabled attribute
The Read Only Attribute
<SELECT>
, <OPTION>
, and <BUTTON>
elements do not have readonly attributes (although thy both have disabled attributes)*-blatant plagiarism from http://kreotekdev.wordpress.com/2007/11/08/disabled-vs-readonly-form-fields/
You can use the sp_columns stored procedure:
exec sp_columns MyTable
import random
def random_zeroes(max_size):
"Create a list of zeros for a random size (up to max_size)."
a = []
for i in xrange(random.randrange(max_size)):
a += [0]
Use range
instead if you are using Python 3.x.
Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.
Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).
When you do spam = "green"
, you have bound the name spam
to the string object "green"
; if you then do eggs = spam
you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs
, to the same object ("green"
in this case). If you then bind spam
to something else (spam = 3.14159
) eggs
will still be bound to "green"
.
When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).
With for-loops utilizing lists, there are two basic ways to assign back to the list:
for i, item in enumerate(some_list):
some_list[i] = process(item)
or
new_list = []
for item in some_list:
new_list.append(process(item))
some_list[:] = new_list
Notice the [:]
on that last some_list
-- it is causing a mutation of some_list
's elements (setting the entire thing to new_list
's elements) instead of rebinding the name some_list
to new_list
. Is this important? It depends! If you have other names besides some_list
bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list
.
I would do this slightly different by applying both the UNPIVOT
and the PIVOT
functions to get the final result. The unpivot takes the values from both the totalcount
and totalamount
columns and places them into one column with multiple rows. You can then pivot on those results.:
select chardate,
Australia_totalcount as [Australia # of Transactions],
Australia_totalamount as [Australia Total $ Amount],
Austria_totalcount as [Austria # of Transactions],
Austria_totalamount as [Austria Total $ Amount]
from
(

If you have an unknown number of country
names, then you can use dynamic SQL:
DECLARE @cols AS NVARCHAR(MAX),
@colsName AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(country +'_'+c.col)
from mytransactions
cross apply
(
select 'TotalCount' col
union all
select 'TotalAmount'
) c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select @colsName
= STUFF((SELECT distinct ', ' + QUOTENAME(country +'_'+c.col)
+' as ['
+ country + case when c.col = 'TotalCount' then ' # of Transactions]' else 'Total $ Amount]' end
from mytransactions
cross apply
(
select 'TotalCount' col
union all
select 'TotalAmount'
) c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set @query
= 'SELECT chardate, ' + @colsName + '
from
(
select
numericmonth,
chardate,
country +''_''+col col,
value
from
(
select numericmonth,
country,
chardate,
cast(totalcount as numeric(10, 2)) totalcount,
cast(totalamount as numeric(10, 2)) totalamount
from mytransactions
) src
unpivot
(
value
for col in (totalcount, totalamount)
) unpiv
) s
pivot
(
sum(value)
for col in (' + @cols + ')
) p
order by numericmonth'
execute(@query)
Both give the result:
| CHARDATE | AUSTRALIA # OF TRANSACTIONS | AUSTRALIA TOTAL $ AMOUNT | AUSTRIA # OF TRANSACTIONS | AUSTRIA TOTAL $ AMOUNT |

Considering we have:
String c = "c"; // character to repeat, for empty it would be " ";
int n = 4; // number of times to repeat
String EMPTY_STRING = ""; // empty string (can be put in utility class)
String resultOne = IntStream.range(0,n)
.mapToObj(i->c).collect(Collectors.joining(EMPTY_STRING)); // cccc
String resultTwo = String.join(EMPTY_STRING, Collections.nCopies(n, c)); //cccc
To compare date time, you can try this. Datetime format can be changed
from datetime import datetime
>>> a = datetime.strptime("10/12/2013", "%m/%d/%Y")
>>> b = datetime.strptime("10/15/2013", "%m/%d/%Y")
>>> a>b

The correct answer (as of Dec 2018) is... you can't. Upgrading conda install python=3.6
may work, but it might not if you have packages that are necessary, but cannot be uninstalled.
Anaconda uses a default environment named base
and you cannot create a new (e.g. python 3.6) environment with the same name. This is intentional. If you want your base Anaconda to be python 3.6, the right way to do this is to install Anaconda for python 3.6. As a package manager, the goal of Anaconda is to make different environments encapsulated, hence why you must source activate into them and why you can't just quietly switch the base package at will as this could lead to many issues on production systems.
but as for this method, I don't understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE.
By starting out with smallest
set to Integer.MAX_VALUE
and largest
set to Integer.MIN_VALUE
, they don't have to worry later about the special case where smallest
and largest
don't have a value yet. If the data I'm looking through has a 10
as the first value, then numbers[i]<smallest
will be true (because 10
is <
Integer.MAX_VALUE
) and we'll update smallest
to be 10
. Similarly, numbers[i]>largest
will be true
because 10
is >
Integer.MIN_VALUE
and we'll update largest
. And so on.
Of course, when doing this, you must ensure that you have at least one value in the data you're looking at. Otherwise, you end up with apocryphal numbers in smallest
and largest
.
Note the point Onome Sotu makes in the comments:
...if the first item in the array is larger than the rest, then the largest item will always be Integer.MIN_VALUE because of the else-if statement.
Which is true; here's a simpler example demonstrating the problem (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = Integer.MAX_VALUE;
int largest = Integer.MIN_VALUE;
for (int value : values) {
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 2 -- WRONG
}
}
To fix it, either:
Don't use else
, or
Start with smallest
and largest
equal to the first element, and then loop the remaining elements, keeping the else if
.
Here's an example of that second one (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = values[0];
int largest = values[0];
for (int n = 1; n < values.length; ++n) {
int value = values[n];
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 5
}
}
Step1:
Go to cordova\platforms\android
ant create a fille called ant.properties
file with the keystore file info (this keystore can be generated from your favorite Android SDK, studio...):
key.store=C:\\yourpath\\Yourkeystore.keystore
key.alias=youralias
Step2:
Go to cordova path and execute:
cordova build android --release
Note: You will be prompted asking your keystore and key password
An YourApp-release.apk will appear in \cordova\platforms\android\ant-build

I wouldn't recommend suppressing the warning output. I would, however, recommend using is_array
instead of !empty
. If $items
happens to be a nonzero scalar, then the foreach
will still error out if you use !empty
.
Unfortunately there really isn't a set set of escape codes since it varies based on the language you are using.
However, keeping a page like the Regular Expression Tools Page or this Regular Expression Cheatsheet can go a long way to help you quickly filter things out.
this is my solution:
<%= link_to root_path do %>
<%= image_tag "image.jpg", class: "some class here" %>
<% end %>
Why don't you style it out:
<canvas id="canvas" width="800" height="600" style="background: url('./images/image.jpg')">
Your browser does not support the canvas element.
</canvas>
A workaround that worked for me (using Backbone.js), was to add "#/" to the end of the redirect URL passed to Facebook. Facebook will keep the provided fragment, and not append its own "_=_".
Upon return, Backbone will remove the "#/" part. For AngularJS, appending "#!" to the return URL should work.
Note that the fragment identifier of the original URL is preserved on redirection (via HTTP status codes 300, 301, 302 and 303) by most browsers, unless the redirect URL also has a fragment identifier. This seems to be recommended behaviour.
If you use a handler script that redirects the user elsewhere, you can append "#" to the redirect URL here to replace the fragment identifier with an empty string.
It sounds like it's your browser caching the image (which I now notice you wrote in your question). You can force the browser to reload the image by passing an extra variable like so:
d = new Date();
$("#myimg").attr("src", "/myimg.jpg?"+d.getTime());
if you set style="height:100px;" on a td if the td has content that grows the cell more than that, it will do so no need for min height on a td.
I’ve found forever to do the job perfectly fine.
Assuming you already have npm installed, if not, just do
sudo apt-get install npm
Then install forever
npm install forever --global
Now you can run it like this
forever start app.js
It's because when you enter a number then press Enter, input.nextInt()
consumes only the number, not the "end of line". Primitive data types like int, double etc do not consume "end of line", therefore the "end of line" remains in buffer and When input.next()
executes, it consumes the "end of line" from buffer from the first input. That's why, your String sentence = scanner.next()
only consumes the "end of line" and does not wait to read from keyboard.
Tip: use scanner.nextLine()
instead of scanner.next()
because scanner.next()
does not read white spaces from the keyboard. (Truncate the string after giving some space from keyboard, only show string before space.)
Make sure you follow the language definition for JSON. In your second example, the section:
"labs":[{
""
}]
Is invalid since an object must be composed of zero or more key-value pairs "a" : "b"
, where "b"
may be any valid value. Some parsers may automatically interpret { "" }
to be { "" : null }
, but this is not a clearly defined case.
Also, you are using a nested array of objects [{}]
quite a bit. I would only do this if:
I can think of a handy use for the custom tag "init"
. Include a JavaScript expression that gets evaluated at document.onLoad()
time and provides a value for the tag, e.g.
<p><p>The UTC date is <span init="new Date().toUTCString()">?</span>.<p></p>
Some boilerplate JavaScript code would scan all the tags in the DOM at document.onload()
time looking for the init attributes, evaluating the expressions that they contain, and assigning them to the containing tag's innerHTML. This would give HTML some of the power of JSP, PHP etc. Currently we have to split the HTML markup and the JavaScript code that illuminates it. Bugs love split code.
Concise if you are just interested in the time elapsed that is under 24 hours. You can format the output as needed in the return statement :
import datetime
def elapsed_interval(start,end):
elapsed = end - start
min,secs=divmod(elapsed.days * 86400 + elapsed.seconds, 60)
hour, minutes = divmod(min, 60)
return '%.2d:%.2d:%.2d' % (hour,minutes,secs)
if __name__ == '__main__':
time_start=datetime.datetime.now()
""" do your process """
time_end=datetime.datetime.now()
total_time=elapsed_interval(time_start,time_end)
Enter the command
which python
//output:
/usr/bin/python
cd /usr/bin
ls -l
Here you can see something like this
lrwxrwxrwx 1 root root 9 Mar 7 17:04 python -> python2.7
your default python2.7 is soft linked to the text 'python'
So remove the softlink python
sudo rm -r python
then retry the above command
ls -l
you can see the softlink is removed
-rwxr-xr-x 1 root root 3670448 Nov 12 20:01 python2.7
Then create a new softlink for python3.6
ln -s /usr/bin/python3.6 python
Then try the command python
in terminal
//output:

Perhaps I'm misunderstanding the intent of your question, so correct me if I'm wrong, but can't you apply the culture settings globally once, and then not worry about customizing every write statement?
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-GB");
Update
I also implemented the following solution in my Python script here on GitHub.
I also verified that damaged files (jpg) frequently are not 'broken' images i.e, a damaged picture file sometimes remains a legit picture file, the original image is lost or altered but you are still able to load it with no errors. But, file truncation cause always errors.
End Update
You can use Python Pillow(PIL) module, with most image formats, to check if a file is a valid and intact image file.
In the case you aim at detecting also broken images, @Nadia Alramli correctly suggests the im.verify()
method, but this does not detect all the possible image defects, e.g., im.verify
does not detect truncated images (that most viewers often load with a greyed area).
Pillow is able to detect these type of defects too, but you have to apply image manipulation or image decode/recode in or to trigger the check. Finally I suggest to use this code:
try:
im = Image.load(filename)
im.verify() #I perform also verify, don't know if he sees other types o defects
im.close() #reload is necessary in my case
im = Image.load(filename)
im.transpose(PIL.Image.FLIP_LEFT_RIGHT)
im.close()
except:
#manage excetions here
In case of image defects this code will raise an exception. Please consider that im.verify is about 100 times faster than performing the image manipulation (and I think that flip is one of the cheaper transformations). With this code you are going to verify a set of images at about 10 MBytes/sec with standard Pillow or 40 MBytes/sec with Pillow-SIMD module (modern 2.5Ghz x86_64 CPU).
For the other formats psd,xcf,.. you can use Imagemagick wrapper Wand, the code is as follows:
im = wand.image.Image(filename=filename)
temp = im.flip;
im.close()
But, from my experiments Wand does not detect truncated images, I think it loads lacking parts as greyed area without prompting.
I red that Imagemagick has an external command identify that could make the job, but I have not found a way to invoke that function programmatically and I have not tested this route.
I suggest to always perform a preliminary check, check the filesize to not be zero (or very small), is a very cheap idea:
statfile = os.stat(filename)
filesize = statfile.st_size
if filesize == 0:
#manage here the 'faulty image' case
Why is floatval the best option for financial comparison data? bc functions only accurately turn strings into real numbers.
try using the Date

You can put \r\n

If you have a class like:

None of these answers worked for me, at least not for scrolling down a facebook search result page, but I found after a lot of testing this solution:

Divs=driver.find_element_by_tag_name('div').text

A slightly clumsier but faster approach for larger datasets involves getting the counts for a column of interest, sorting the counts highest to lowest, and then de-duplicating on a subset to only retain the largest cases. The code example is following:
>>> import pandas as pd
>>> source = pd.DataFrame(
{
'Country': ['USA', 'USA', 'Russia', 'USA'],
'City': ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
'Short name': ['NY', 'New', 'Spb', 'NY']
}
)
>>> grouped_df = source\
.groupby(['Country','City','Short name'])[['Short name']]\
.count()\
.rename(columns={'Short name':'count'})\
.reset_index()\
.sort_values('count', ascending=False)\
.drop_duplicates(subset=['Country', 'City'])\
.drop('count', axis=1)
>>> print(grouped_df)
Country City Short name
1 USA New-York NY
0 Russia Sankt-Petersburg Spb
Another option (depending on the use case) would be to use DataMystic's TextPipe and DataPipe products. I've used them in the past, and they've worked great in the complex replacement scenarios, and without having to export data out of the database for find-and-replace.
As of pandas 0.20.3, use .to_pydatetime()
to convert any pandas.DateTimeIndex
instances to Python datetime.datetime
.
For those who are interested, I have created django-better-choices
library, that provides a nice interface to work with Django choices for Python 3.7+. It supports custom parameters, lots of useful features and is very IDE friendly.
You can define your choices as a class:
from django_better_choices import Choices
class PAGE_STATUS(Choices):
CREATED = 'Created'
PENDING = Choices.Value('Pending', help_text='This set status to pending')
ON_HOLD = Choices.Value('On Hold', value='custom_on_hold')
VALID = Choices.Subset('CREATED', 'ON_HOLD')
class INTERNAL_STATUS(Choices):
REVIEW = 'On Review'
@classmethod
def get_help_text(cls):
return tuple(
value.help_text
for value in cls.values()
if hasattr(value, 'help_text')
)
Then do the following operations and much much more:
print( PAGE_STATUS.CREATED ) # 'created'
print( PAGE_STATUS.ON_HOLD ) # 'custom_on_hold'
print( PAGE_STATUS.PENDING.display ) # 'Pending'
print( PAGE_STATUS.PENDING.help_text ) # 'This set status to pending'
'custom_on_hold' in PAGE_STATUS.VALID # True
PAGE_STATUS.CREATED in PAGE_STATUS.VALID # True
PAGE_STATUS.extract('CREATED', 'ON_HOLD') # ~= PAGE_STATUS.VALID
for value, display in PAGE_STATUS:
print( value, display )
PAGE_STATUS.get_help_text()
PAGE_STATUS.VALID.get_help_text()
And of course, it is fully supported by Django and Django Migrations:
class Page(models.Model):
status = models.CharField(choices=PAGE_STATUS, default=PAGE_STATUS.CREATED)
Full documentation here: https://pypi.org/project/django-better-choices/
if we are using JpaRepository then it will internally created the queries.
Sample
findByLastnameAndFirstname(String lastname,String firstname)
findByLastnameOrFirstname(String lastname,String firstname)
findByStartDateBetween(Date date1,Date2)
findById(int id)
Note
if suppose we need complex queries then we need to write manual queries like
@Query("SELECT salesOrder FROM SalesOrder salesOrder WHERE salesOrder.clientId=:clientId AND salesOrder.driver_username=:driver_username AND salesOrder.date>=:fdate AND salesOrder.date<=:tdate ")
@Transactional(readOnly=true)
List<SalesOrder> findAllSalesByDriver(@Param("clientId")Integer clientId, @Param("driver_username")String driver_username, @Param("fdate") Date fDate, @Param("tdate") Date tdate);

}
To fetch top viewController on which we show topBanner
extension UIApplication {
class func getTopViewController(base: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController? {

return getTopViewController(base: nav.visibleViewController)
} else if let tab = base as? UITabBarController, let selected = tab.selectedViewController {
return getTopViewController(base: selected)
} else if let presented = base?.presentedViewController {
return getTopViewController(base: presented)
}
return base

There is a section in the MySQL manual on how to reset the root password which will solve your problem.
You can try: a=[0,1,2,3,4,5,6,7,8,9];

Take note, there are a few certain things to take note when running backslashes with specific characters.

You need to store the psftp script (lines from open
to bye
) into a separate file and pass that to psftp
using -b
switch:
cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b
EDIT: For username+password: As you cannot use psftp
commands in a batch file, for the same reason, you cannot specify the username and the password as psftp
commands. These are inputs to the open
command. While you can specify the username with the open
command (open <user>@<IP>
), you cannot specify the password this way. This can be done on a psftp
command line only. Then it's probably cleaner to do all on the command-line:
cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>
And remove the open
, <user>
and <PW>
lines from your script.txt
.
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw
What you are doing atm is that you run psftp
without any parameter or commands. Once you exit it (like by typing bye
), your batch file continues trying to run open
command (and others), what Windows shell obviously does not understand.
If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:
(
echo cd ...
echo lcd ...
echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

time_in_millis = 1596542285000
dt = datetime.datetime.fromtimestamp(time_in_millis / 1000.0, tz=datetime.timezone.utc)
Converting datetime to string following the RFC3339 standard (used by Open API specification):
from rfc3339 import rfc3339
converted_to_str = rfc3339(dt, utc=True, use_system_timezone=False)

The answer was surprisingly simple. I had to add a Content-Type
header in the POST
request with a value of application/json
. Without this header Jersey did not know what to do with the request body (in spite of the @Consumes(MediaType.APPLICATION_JSON)
annotation)!
You can very easily create an EXE (for Windows) without using any cryptic build commands. You can do it right in Visual Studio.
You can use an inline comment: // eslint-disable-next-line rule-name
.
// eslint-disable-next-line no-console
console.log('eslint will ignore the no-console on this line of code');

I think the issue is what do you want to happen when the query has no results. If this is an exceptional case then I would wrap the query in a try/catch block and handle the exception that the standard query generates. If it's ok to have the query return no results, then you need to figure out what you want the result to be in that case. It may be that @David's answer (or something similar will work). That is, if the MAX will always be positive, then it may be enough to insert a known "bad" value into the list that will only be selected if there are no results. Generally, I would expect a query that is retrieving a maximum to have some data to work on and I would go the try/catch route as otherwise you are always forced to check if the value you obtained is correct or not. I'd rather that the non-exceptional case was just able to use the obtained value.
Try
Dim x = (From y In context.MyTable _
Where y.MyField = value _
Select y.MyCounter).Max
... continue working with x ...
Catch ex As SqlException
... do error processing ...
End Try

Use this library. Follow the instruction mention in this repo.
Remember don't use dd()

You can remove bullets by setting the list-style-type
to none
on the CSS for the parent element (typically a <ul>
), for example:
ul {
list-style-type: none;
}
You might also want to add padding: 0
and margin: 0
to that if you want to remove indentation as well.
See Listutorial for a great walkthrough of list formatting techniques.
If you are looking for retrieving remote user IDSID/Username, use:
echo gethostbyaddr($_SERVER['REMOTE_ADDR']);
You will get something like iamuser1-mys.corp.company.com
Filter the rest of the domain behind, and you are able to get the idsid only.

I think you can just do
std::string s( MyVector.begin(), MyVector.end() );
where MyVector is your std::vector.
In (ANSI) C99, you can use a designated initializer to initialize a structure:
MY_TYPE a = { .flag = true, .value = 123, .stuff = 0.456 };
Edit: Other members are initialized as zero: "Omitted field members are implicitly initialized the same as objects that have static storage duration." (https://gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html)
Combining the advice from MartinP and user664833, I was also able to get it to work. Caveat is that entering psql from the pgAdmin GUI tool via choosing Plugins...PSQL Console sets the credentials and permission level for the psql session, so you must have Admin or CRUD permissions on the table and maybe also Admin on the DB (do not know for sure on that). The command then in the psql console would take this form:
postgres=# \i driveletter:/folder_path/backupfilename.backup
where postgres=# is the psql prompt, not part of the command.
The .backup file will include the commands used to create the table, so you may also get things like "ALTER TABLE ..." commands in the file that get executed but reported as errors. I suppose you can always delete these commands before running the restore but you're probably better safe than sorry to keep them in there, as these will not likely cause the restore of data to fail. But always check to be sure the data you wanted to resore actually got there. (Sorry if this seems like patronizing advice to anyone, but it's an oversight that can happen to anyone no matter how long they have been at this stuff -- a moment's distraction from a colleague, a phone call, etc., and it's easy to forget this step. I have done it myself using other databases earlier in my career and wondered "Gee, why am I not seeing any data back from this query?" Answer was the data never actually got restored, and I just wasted 2 hours trying to hunt down suspected possible bugs that didn't exist.)
I found out that it also happens if you uninstalled some packages from your react-native project and there is still packages in your build gradle dependencies in the bottom of page like:
{
project(':react-native-sound-player')
}
You can use df.dropDuplicates(['col1','col2'])
to get only distinct rows based on colX in the array.
There is no other way - except implementing lazy loading.
Or manual loading....
myobj = context.MyObjects.First();
myobj.ChildA.Load();
myobj.ChildB.Load();
...
Please try this (if the browser does not support "onbeforeunload"):
jQuery(document).ready(function($) {
if (window.history && window.history.pushState) {
$(window).on('popstate', function() {
var hashLocation = location.hash;
var hashSplit = hashLocation.split("#!/");
var hashName = hashSplit[1];
if (hashName !== '') {
var hash = window.location.hash;
if (hash === '') {
alert('Back button was pressed.');
}
}
});
window.history.pushState('forward', null, './#forward');
}
});
In addition to the PHP frame encoding function, here follows a decode function:
function Decode($M){
$M = array_map("ord", str_split($M));
$L = $M[1] AND 127;
if ($L == 126)
$iFM = 4;
else if ($L == 127)
$iFM = 10;
else
$iFM = 2;
$Masks = array_slice($M, $iFM, 4);
$Out = "";
for ($i = $iFM + 4, $j = 0; $i < count($M); $i++, $j++ ) {
$Out .= chr($M[$i] ^ $Masks[$j % 4]);
}
return $Out;
}
I've implemented this and also other functions in an easy-to-use WebSocket PHP class here.
From git stash --help
Recovering stashes that were cleared/dropped erroneously
If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
following incantation to get a list of stashes that are still in your repository, but not reachable any more:
git fsck --unreachable |
grep commit | cut -d\ -f3 |
xargs git log --merges --no-walk --grep=WIP
This helped me better than the accepted answer with the same scenario.
When you type exit
in the command line, it finds the variable with that name and calls __repr__
(or __str__
) on it. Usually, you'd get a result like:
<function exit at 0x00B97FB0>
But they decided to redefine that function for the exit
object to display a helpful message instead. Whether or not that's a stupid behavior or not, is a subjective question, but one possible reason why it doesn't "just exit" is:
Suppose you're looking at some code in a debugger, for instance, and one of the objects references the exit
function. When the debugger tries to call __repr__
on that object to display that function to you, the program suddenly stops! That would be really unexpected, and the measures to counter that might complicate things further (for instance, even if you limit that behavior to the command line, what if you try to print some object that have exit
as an attribute?)
I made this jQuery extension to print the HTML of the element selected: $('#div2').print();
$.fn.extend({
print: function() {
var frameName = 'printIframe';
var doc = window.frames[frameName];
if (!doc) {
$('<iframe>').hide().attr('name', frameName).appendTo(document.body);
doc = window.frames[frameName];
}
doc.document.body.innerHTML = this.html();
doc.window.print();
return this;
}
});

You could easily use:
label1.Text = dateTimePicker1.Value.Date.ToString("dd/MM/yyyy")
and if you want to change '/' or '-', just add this:
label1.Text = label1.Text.Replace(".", "-")

Got similar issue. Try to set more time in driver's constructor - add eg.

If it is exactly null
(as opposed to not set):
db.states.find({"cities.name": null})
(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).
If it's the case that the property is not set:
db.states.find({"cities.name": {"$exists": false}})
I've tested the above with a collection created with these two inserts:
db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})
The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or
query:
db.states.find({"$or": [
{"cities.name": null},
{"cities.name": {"$exists": false}}
]})
Try this : MyTextBox.Focus ( );
Instead of using onload, use Angular's ng-init
.
<article id="showSelector" ng-controller="CinemaCtrl" ng-init="myFunction()">
Note: This requires that myFunction is a property of the CinemaCtrl
scope.
For anyone whom might still have this problem using jQuery 2.0 (I know I do), Jay Dave wrote the best jQuery workaround but I still have a few things to add to his code namely:
The complete code is below:
// add ajax transport method for cross domain requests when using IE9
if('XDomainRequest' in window && window.XDomainRequest !== null) {
$.ajaxTransport("+*", function( options, originalOptions, jqXHR ) {
// verify if we need to do a cross domain request
// if not return so we don't break same domain requests
if (typeof options.crossDomain === 'undefined' || !options.crossDomain) {
return;
}
var xdr;
return {
send: function( headers, completeCallback ) {
// Use Microsoft XDR
xdr = new XDomainRequest();
xdr.open("get", options.url); // NOTE: make sure protocols are the same otherwise this will fail silently
xdr.onload = function() {
if(this.contentType.match(/\/xml/)){
var dom = new ActiveXObject("Microsoft.XMLDOM");
dom.async = false;
dom.loadXML(this.responseText);
completeCallback(200, "success", [dom]);
} else {
completeCallback(200, "success", [this.responseText]);
}
};
xdr.onprogress = function() {};
xdr.ontimeout = function(){
completeCallback(408, "error", ["The request timed out."]);
};
xdr.onerror = function(){
completeCallback(404, "error", ["The requested resource could not be found."]);
};
xdr.send();
},
abort: function() {
if(xdr) xdr.abort();
}
};
});
}
The fundamental problem can often be simply solved by changing an =
to IN
, in cases where you've got a one-to-many relationship. For example, if you wanted to update or delete a bunch of accounts for a given customer:
WITH accounts_to_delete AS
(
SELECT account_id
FROM accounts a
INNER JOIN customers c
ON a.customer_id = c.id
WHERE c.customer_name='Some Customer'
)
-- this fails if "Some Customer" has multiple accounts, but works if there's 1:
DELETE FROM accounts
WHERE accounts.guid =
(
SELECT account_id
FROM accounts_to_delete
);
-- this succeeds with any number of accounts:
DELETE FROM accounts
WHERE accounts.guid IN
(
SELECT account_id
FROM accounts_to_delete
);
One more idea for you. Create a rake task that calls rails server with the -p.
task "start" => :environment do
system 'rails server -p 3001'
end
then call rake start
instead of rails server

In new page-plugin you can do multiple tabs in your website. The Page plugin lets you easily embed and promote any Facebook Page on your website. Just like on Facebook, your visitors can like and share the Page without leaving your site.
<body>
tag. <div id="fb-root"></div>_x000D_
<script>(function(d, s, id) {_x000D_
var js, fjs = d.getElementsByTagName(s)[0];_x000D_
if (d.getElementById(id)) return;_x000D_
js = d.createElement(s); js.id = id;_x000D_
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.5&appId={APP_ID}";_x000D_
fjs.parentNode.insertBefore(js, fjs);_x000D_
}(document, 'script', 'facebook-jssdk'));</script>
_x000D_
<div class="fb-page" _x000D_

data-tabs="timeline,events,messages"_x000D_
data-href="https://www.facebook.com/YourPageName"_x000D_

Try marginTop
in place of margin-top
, eg:
$("#ActionBox").css("marginTop", foo);
jQuery("#input").live('change', function() {
// since we check more than once against the value, place it in a var.
var inputvalue = $("#input").attr("value");
// if it's value **IS NOT** ""
if(inputvalue !== "") {
jQuery(this).css('outline', 'solid 1px red');
}
// else if it's value **IS** ""
else if(inputvalue === "") {
alert('empty');
}
});
You can select every column from that sub-query by aliasing it and adding the alias before the *
:
SELECT t.*, a+b AS total_sum
FROM
(
SELECT SUM(column1) AS a, SUM(column2) AS b
FROM table
) t
Use .prop()
instead and if we go with your code then compare like this:
Look at the example jsbin:
$("#news_list tr").click(function () {
var ele = $(this).find(':checkbox');
if ($(':checked').length) {
ele.prop('checked', false);
$(this).removeClass('admin_checked');
} else {
ele.prop('checked', true);
$(this).addClass('admin_checked');
}
});
Changes:
input
to :checkbox
.the length
of the checked checkboxes
.Nothing easier than that man. Try this one:
<?xml version="1.0" encoding="iso-8859-1"?>

<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.1/jquery-ui.min.js"></script>
<style>
.loading { background: url(/img/spinner.gif) center no-repeat !important}
</style>
</head>
<body>
<a class="ajax" href="http://www.google.com">
Open as dialog
</a>
<script type="text/javascript">
$(function (){
$('a.ajax').click(function() {
var url = this.href;
// show a spinner or something via css
var dialog = $('<div style="display:none" class="loading"></div>').appendTo('body');
// open the dialog
dialog.dialog({
// add a close listener to prevent adding multiple divs to the document
close: function(event, ui) {
// remove div with all data and events
dialog.remove();
},
modal: true
});
// load remote content
dialog.load(
url,
{}, // omit this param object to issue a GET request instead a POST request, otherwise you may provide post parameters within the object
function (responseText, textStatus, XMLHttpRequest) {
// remove the loading class
dialog.removeClass('loading');
}
);
//prevent the browser to follow the link
return false;
});
});
</script>
</body>
</html>
Note that you can't load remote from local, so you'll have to upload this to a server or whatever. Also note that you can't load from foreign domains, so you should replace href of the link to a document hosted on the same domain (and here's the workaround).

I was using ASP.NET 4.5 MVC application on IIS 7. My fix was to set runallmanagedmodule to true.
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
or If you have other modules, you may want to add them inside the module tag.
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<add name="ErrorLogWeb" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
...
</modules>
</system.webServer>
If you are using wamp server , then i recommend you to use xampp server . you . i get this error in less than i minute but i resolved this by using (isset) function . and i get no error . and after that i remove (isset) function and i don,t see any error.

Try this small lib, works with Angular 5.0.0
Quickstart example with ng2-file-upload 1.3.0:
User clicks custom button, which triggers upload dialog from hidden input type="file" , uploading started automatically after selecting single file.
app.module.ts:
import {FileUploadModule} from "ng2-file-upload";
your.component.html:
...
<button mat-button onclick="document.getElementById('myFileInputField').click()" >
Select and upload file
</button>
<input type="file" id="myFileInputField" ng2FileSelect [uploader]="uploader" style="display:none">
...
your.component.ts:
import {FileUploader} from 'ng2-file-upload';
...
uploader: FileUploader;
...
constructor() {
this.uploader = new FileUploader({url: "/your-api/some-endpoint"});
this.uploader.onErrorItem = item => {
console.error("Failed to upload");
this.clearUploadField();
};
this.uploader.onCompleteItem = (item, response) => {
console.info("Successfully uploaded");
this.clearUploadField();
// (Optional) Parsing of response
let responseObject = JSON.parse(response) as MyCustomClass;
};
// Asks uploader to start upload file automatically after selecting file
this.uploader.onAfterAddingFile = fileItem => this.uploader.uploadAll();
}
private clearUploadField(): void {
(<HTMLInputElement>window.document.getElementById('myFileInputField'))
.value = "";
}
Alternative lib, works in Angular 4.2.4, but requires some workarounds to adopt to Angular 5.0.0
The state should be managed in the parent component. You can transfer the open
value to the child component by adding a property.
class ParentComponent extends Component {
constructor(props) {
super(props);
this.state = {
open: false
};
this.toggleChildMenu = this.toggleChildMenu.bind(this);
}
toggleChildMenu() {
this.setState(state => ({
open: !state.open
}));
}
render() {
return (
<div>
<button onClick={this.toggleChildMenu}>
Toggle Menu from Parent
</button>
<ChildComponent open={this.state.open} />
</div>
);
}
}
class ChildComponent extends Component {
render() {
return (
<Drawer open={this.props.open}/>
);
}
}
If I'm understanding you correctly, you should be able to do this in one query, joining table1 and table2 together:
INSERT INTO table3 { name, age, sex, city, id, number}
SELECT p.name, p.age, p.sex, p.city, p.id, c.number
FROM table1 p
INNER JOIN table2 c ON c.Id = p.Id
You can also try using String Tokeniser, for any space, tab, newline, and all. A simple way is,
String s = "Your Text Here";
StringTokenizer st = new StringTokenizer( s, " " );

JonH has covered very well the part on how to write the query. There is another significant issue that must be mentioned too, however, which is the performance characteristics of such a query. Let's repeat it here (adapted to Oracle):
SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(EmployeeName) > 4;
This query is restricting the result of a function applied to a column value (the result of applying the LENGTH
function to the EmployeeName
column). In Oracle, and probably in all other RDBMSs, this means that a regular index on EmployeeName will be useless to answer this query; the database will do a full table scan, which can be really costly.
However, various databases offer a function indexes feature that is designed to speed up queries like this. For example, in Oracle, you can create an index like this:
CREATE INDEX EmployeeTable_EmployeeName_Length ON EmployeeTable(LENGTH(EmployeeName));
This might still not help in your case, however, because the index might not be very selective for your condition. By this I mean the following: you're asking for rows where the name's length is more than 4. Let's assume that 80% of the employee names in that table are longer than 4. Well, then the database is likely going to conclude (correctly) that it's not worth using the index, because it's probably going to have to read most of the blocks in the table anyway.
However, if you changed the query to say LENGTH(EmployeeName) <= 4
, or LENGTH(EmployeeName) > 35
, assuming that very few employees have names with fewer than 5 character or more than 35, then the index would get picked and improve performance.
Anyway, in short: beware of the performance characteristics of queries like the one you're trying to write.
Oracle JavaFX from Java SE supports only OS X (macOS), GNU/Linux and Microsoft Windows. On these platforms, JavaFX applications are typically run on JVM from Java SE or OpenJDK.
There is also a JavaFXPorts project, which is an open-source project sponsored by a third-party. It aims to port JavaFX library to Android and iOS.
On Android, this library can be used like any other Java library; the JVM bytecode is compiled to Dalvik bytecode. It's what people mean by saying that "Android runs Java".
On iOS, situation is a bit more complex, as neither Java SE nor OpenJDK supports Apple mobile devices. Till recently, the only sensible option was to use RoboVM ahead-of-time Java compiler for iOS. Unfortunately, on 15 April 2015, RoboVM project was shut down.
One possible alternative is Intel's Multi-OS Engine. Till recently, it was a proprietary technology, but on 11 August 2016 it was open-sourced. Although it can be possible to compile an iOS JavaFX app using JavaFXPorts' JavaFX implementation, there is no evidence for that so far. As you can see, the situation is dynamically changing, and this answer will be hopefully updated when new information is available.
With Windows Phone it's simple: there is no JavaFX support of any kind.
