It is as simple as the following :)
@keyframes fadeout {
0% { opacity: 1; height: auto; }
90% { opacity: 0; height: auto; }
100% { opacity: 0; height: 0;
}
animation: fadeout linear 0.5s 1 normal forwards !important;
Get it to fade away, and then make it height 0;
. Also make sure to use forwards so that it stays in the final state.
Don't forget to include
import Image
In order to show it use this :
Image.open('pathToFile').show()
You can use String.Join
. If you have a List<string>
then you can call ToArray
first:
List<string> names = new List<string>() { "John", "Anna", "Monica" };
var result = String.Join(", ", names.ToArray());
In .NET 4 you don't need the ToArray
anymore, since there is an overload of String.Join
that takes an IEnumerable<string>
.
Results:
John, Anna, Monica
While other answers have noted the differences correctly, note that if you are in fact returning a ViewResult only it is better to return the more specific type rather than the base ActionResult type. An obvious exception to this principle is when your method returns multiple types deriving from ActionResult.
For a full discussion of the reasons behind this principle please see the related discussion here: Must ASP.NET MVC Controller Methods Return ActionResult?
According to the git-stash manpage, "A stash is represented as a commit whose tree records the state of the working directory, and its first parent is the commit at HEAD
when the stash was created," and git stash show -p
gives us "the changes recorded in the stash as a diff between the stashed state and its original parent.
To keep your other changes intact, use git stash show -p | patch --reverse
as in the following:
$ git init

I've been finding this really handy lately...
Use the Java 8 way of converting a Map<String, Object>
to Map<String, String>
. This solution handles null
values.
Map<String, String> keysValuesStrings = keysValues.entrySet().stream()
.filter(entry -> entry.getValue() != null)
.collect(Collectors.toMap(Entry::getKey, entry -> entry.getValue().toString()));
As said by Sparky in comments on many answers to this question, there is NOT any textarea
value for the type
attribute of the input
tag.
On other terms, the following markup is not valid :
<input type="textarea" />
And the browser replaces it by the default :
<input type="text" />
To define a multi-lines text input, use :
<textarea></textarea>
See the textarea element documentation for more details.
This solution is the most complete. It takes in consideration: UINavigationController UIPageViewController UITabBarController And the topmost presented view controller from the top view controller
The example is in Swift 3.
There are 3 overloads
//Get the topmost view controller for the current application.
public func MGGetTopMostViewController() -> UIViewController? {
if let currentWindow:UIWindow = UIApplication.shared.keyWindow {
return MGGetTopMostViewController(fromWindow: currentWindow)
}
return nil
}
//Gets the topmost view controller from a specific window.
public func MGGetTopMostViewController(fromWindow window:UIWindow) -> UIViewController? {
if let rootViewController:UIViewController = window.rootViewController
{
return MGGetTopMostViewController(fromViewController: rootViewController)
}
return nil
}
//Gets the topmost view controller starting from a specific UIViewController
//Pass the rootViewController into this to get the apps top most view controller
public func MGGetTopMostViewController(fromViewController viewController:UIViewController) -> UIViewController {
//UINavigationController
if let navigationViewController:UINavigationController = viewController as? UINavigationController {
let viewControllers:[UIViewController] = navigationViewController.viewControllers
if navigationViewController.viewControllers.count >= 1 {
return MGGetTopMostViewController(fromViewController: viewControllers[viewControllers.count - 1])
}
}
//UIPageViewController
if let pageViewController:UIPageViewController = viewController as? UIPageViewController {
if let viewControllers:[UIViewController] = pageViewController.viewControllers {
if viewControllers.count >= 1 {
return MGGetTopMostViewController(fromViewController: viewControllers[0])
}
}
}
//UITabViewController
if let tabBarController:UITabBarController = viewController as? UITabBarController {
if let selectedViewController:UIViewController = tabBarController.selectedViewController {
return MGGetTopMostViewController(fromViewController: selectedViewController)
}
}
//Lastly, Attempt to get the topmost presented view controller
var presentedViewController:UIViewController! = viewController.presentedViewController
var nextPresentedViewController:UIViewController! = presentedViewController?.presentedViewController
//If there is a presented view controller, get the top most prensentedViewController and return it.
if presentedViewController != nil {
while nextPresentedViewController != nil {
//Set the presented view controller as the next one.
presentedViewController = nextPresentedViewController
//Attempt to get the next presented view controller
nextPresentedViewController = presentedViewController.presentedViewController
}
return presentedViewController
}
//If there is no topmost presented view controller, return the view controller itself.
return viewController
}
To attempt command line arguments directly is not possible.
One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).
This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html
so sudo systemctl restart myprog -v
-- systemctl will think you're trying to set one of its flags, not myprog's flag.
sudo systemctl restart myprog someotheroption
-- systemctl will restart myprog and the someotheroption service, if it exists.
In Powershell, you'll need to import the active directory module, then use the get-adgroupmember, and then measure-object. For example, to get the number of users belonging to the group "domain users", do the following:
Import-Module activedirecotry
Get-ADGroupMember "domain users" | Measure-Object
When entering the group name after "Get-ADGroupMember", if the name is a single string with no spaces, then no quotes are necessary. If the group name has spaces in it, use the quotes around it.
The output will look something like:
Count : 12345
Average :
Sum :
Maximum :
Minimum :
Property :
Note - importing the active directory module may be redundant if you're already using PowerShell for other AD admin tasks.
Lombok Issue #78 references this page https://www.donneo.de/2015/09/16/lomboks-builder-annotation-and-inheritance/ with this lovely explanation:
@AllArgsConstructor public class Parent { private String a; } public class Child extends Parent { private String b; @Builder public Child(String a, String b){ super(a); this.b = b; } }
As a result you can then use the generated builder like this:
Child.builder().a("testA").b("testB").build();
The official documentation explains this, but it doesn’t explicitly point out that you can facilitate it in this way.
I also found this works nicely with Spring Data JPA.
If you are using the SQL Expression Style approach there is another way to construct the count statement if you already have your table object.
Preparations to get the table object. There are also different ways.
import sqlalchemy
database_engine = sqlalchemy.create_engine("connection string")
# Populate existing database via reflection into sqlalchemy objects
database_metadata = sqlalchemy.MetaData()
database_metadata.reflect(bind=database_engine)
table_object = database_metadata.tables.get("table_name") # This is just for illustration how to get the table_object
Issuing the count query on the table_object
query = table_object.count()
# This will produce something like, where id is a primary key column in "table_name" automatically selected by sqlalchemy
# 'SELECT count(table_name.id) AS tbl_row_count FROM table_name'
count_result = database_engine.scalar(query)
C# extension method code, focus element, enter text, call change().
public static void EnterText(this IWebDriver driver, IWebElement element, string textToEnter)
{
var js = (IJavaScriptExecutor)driver;
js.ExecuteScript("arguments[0].focus();", element);
js.ExecuteScript("arguments[0].setAttribute('value', arguments[1])", element, textToEnter);
js.ExecuteScript("$(arguments[0]).change();", element);
}
Called by:
driver.EnterText(element, text);
Using new Function() is better than eval, but still should only be used with safe input.
const parseJSON = obj => Function('"use strict";return (' + obj + ')')();
console.log(parseJSON("{a:(4-1), b:function(){}, c:new Date()}"))
// outputs: Object { a: 3, b: b(), c: Date 2019-06-05T09:55:11.777Z }
If you don't want to import the calendar library, and need something that is a bit more robust -- you can make your code a little bit more dynamic to inconsistent text input than some of the other solutions provided. You can:
month_to_number
dictionary.items()
of that dictionary and check if the lowercase of a string s
is in a lowercase key k
.month_to_number = {
'January' : 1,
'February' : 2,
'March' : 3,
'April' : 4,
'May' : 5,
'June' : 6,
'July' : 7,
'August' : 8,
'September' : 9,
'October' : 10,
'November' : 11,
'December' : 12}
s = 'jun'
[v for k, v in month_to_number.items() if s.lower() in k.lower()][0]
Out[1]: 6
Likewise, if you have a list l
instead of a string, you can add another for
to loop through the list. The list I have created has inconsistent values, but the output is still what would be desired for the correct month number:
l = ['January', 'february', 'mar', 'Apr', 'MAY', 'JUne', 'july']
[v for k, v in month_to_number.items() for m in l if m.lower() in k.lower()]
Out[2]: [1, 2, 3, 4, 5, 6, 7]
The use case for me here is that I am using Selenium
to scrape data from a website by automatically selecting a dropdown value based off of some conditions. Anyway, this requires me relying on some data that I believe our vendor is manually entering to title each month, and I don't want to come back to my code if they format something slightly differently than they have done historically.
This might be known by most of us, but anyway (I was puzzled my first time):
Doing :set et
(:set
expandtabs) does not change the tabs already existing in the file, one has to do :retab
.
For example:
:set et
:retab
and the tabs in the file are replaced by enough spaces. To have tabs back simply do:
:set noet
:retab
We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:
https://gitlab.example.com/<group>/<project>/commit/<commit hash>
We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.
Use the CX register to count the loops
mov cx, 3 startloop: cmp cx, 0 jz endofloop push cx loopy: Call ClrScr pop cx dec cx jmp startloop endofloop: ; Loop ended ; Do what ever you have to do here
This simply loops around 3 times calling ClrScr
, pushing the CX register onto the stack, comparing to 0, jumping if ZeroFlag is set then jump to endofloop
. Notice how the contents of CX is pushed/popped on/off the stack to maintain the flow of the loop.
Yet another solution.
Add ErrorControllers or static page to with 404 error information.
Modify your web.config (in case of controller).
<system.web>
<customErrors mode="On" >
<error statusCode="404" redirect="~/Errors/Error404" />
</customErrors>
</system.web>
Or in case of static page
<system.web>
<customErrors mode="On" >
<error statusCode="404" redirect="~/Static404.html" />
</customErrors>
</system.web>
This will handle both missed routes and missed actions.
Use strtotime(..)
:
$timestamp = strtotime($mysqltime);
echo date("Y-m-d H:i:s", $timestamp);
Also check this out (to do it in MySQL way.)

Environment Entries specified by <Environment>
markup are JNDI, accessible using InitialContext.lookup under java:/comp/env
. You can specify environment properties to the JNDI by using the environment parameter to the InitialContext constructor and application resource files.
System.getEnv()
is about system environment variables of the tomcat process itself.
To set an environment variable using bash command :
export TOMCAT_OPTS=-Dmy.bar=foo
and start the Tomcat :
./startup.sh
To retrieve the value of System property bar
use System.getProperty()
. System.getEnv()
can be used to retrieve the environment variable i.e. TOMCAT_OPTS
.
Its Working Properly
EditText et_mobile= (EditText) findViewById(R.id.edittxt);
et_mobile.setOnFocusChangeListener(new OnFocusChangeListener() {

if (et_mobile.getText().toString().trim().length() == 0) {
CommonMethod.showAlert("Please enter name", FeedbackSubmtActivity.this);
}
}
}
});
public static void showAlert(String message, Activity context) {
final AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage(message).setCancelable(false)

}
});
try {
builder.show();
} catch (Exception e) {
e.printStackTrace();
}
}
"Performance and speed"? Aren't those kind of ... synonyms, here?
Anyway, the recv()
call takes flags that read()
doesn't, which makes it more powerful, or at least more convenient. That is one difference. I don't think there is a significant performance difference, but haven't tested for it.
I find something simple like this to be much more concise and readable personally.
function pick(arg, def) {
return (typeof arg == 'undefined' ? def : arg);
}
function myFunc(x) {
x = pick(x, 'my default');
}
This is the way I am using at this moment... it's very complicated but at least it handles all the possible situations. In case anyone is interested.
public final class MyFragment extends Fragment {
private TextView vstup;
private Bundle savedState = null;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.whatever, null);
vstup = (TextView)v.findViewById(R.id.whatever);
/* (...) */
/* If the Fragment was destroyed inbetween (screen rotation), we need to recover the savedState first */
/* However, if it was not, it stays in the instance from the last onDestroyView() and we don't want to overwrite it */
if(savedInstanceState != null && savedState == null) {
savedState = savedInstanceState.getBundle(App.STAV);
}
if(savedState != null) {
vstup.setText(savedState.getCharSequence(App.VSTUP));
}
savedState = null;
return v;
}
@Override
public void onDestroyView() {
super.onDestroyView();
savedState = saveState(); /* vstup defined here for sure */
vstup = null;
}
private Bundle saveState() { /* called either from onDestroyView() or onSaveInstanceState() */
Bundle state = new Bundle();
state.putCharSequence(App.VSTUP, vstup.getText());
return state;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
/* If onDestroyView() is called first, we can use the previously savedState but we can't call saveState() anymore */
/* If onSaveInstanceState() is called first, we don't have savedState, so we need to call saveState() */
/* => (?:) operator inevitable! */
outState.putBundle(App.STAV, (savedState != null) ? savedState : saveState());
}
/* (...) */
}
Alternatively, it is always a possibility to keep the data displayed in passive View
s in variables and using the View
s only for displaying them, keeping the two things in sync. I don't consider the last part very clean, though.
It depends.
When you commit to sending output to stdout
, you're basically leaving it up to the user to decide where that output should go.
If you use printf(...)
(or the equivalent fprintf(stdout, ...)
), you're sending the output to stdout
, but where that actually ends up can depend on how I invoke your program.
If I launch your program from my console like this, I'll see output on my console:
$ prog
Hello, World! # <-- output is here on my console
However, I might launch the program like this, producing no output on the console:
$ prog > hello.txt
but I would now have a file "hello.txt" with the text "Hello, World!" inside, thanks to the shell's redirection feature.
Who knows – I might even hook up some other device and the output could go there. The point is that when you decide to print to stdout
(e.g. by using printf()
), then you won't exactly know where it will go until you see how the process is launched or used.
Stripping things down to basics this is what you would want to test with:
import socket
server = socket.socket()
server.bind(("10.0.0.1", 6677))
server.listen(4)
client_socket, client_address = server.accept()
print(client_address, "has connected")
while 1==1:
recvieved_data = client_socket.recv(1024)
print(recvieved_data)
This works assuming a few things:
Try the following, open the start menu, in the "search" field type cmd
and press enter.
Once the black console opens up type ping www.google.com
and this should give you and IP address for google. This address is googles local IP and they bind to that and obviously you can not bind to an IP address owned by google.
With that in mind, you own your own set of IP addresses.
First you have the local IP of the server, but then you have the local IP of your house.
In the below picture 192.168.1.50
is the local IP of the server which you can bind to.
You still own 83.55.102.40
but the problem is that it's owned by the Router and not your server. So even if you visit http://whatsmyip.com and that tells you that your IP is 83.55.102.40
that is not the case because it can only see where you're coming from.. and you're accessing your internet from a router.
In order for your friends to access your server (which is bound to 192.168.1.50
) you need to forward port 6677
to 192.168.1.50
and this is done in your router.
Assuming you are behind one.
If you're in school there's other dilemmas and routers in the way most likely.
Let's think a little different, You can use static parameters:
class global {
static $foo = "bar";
}
And you can use and modify it every where you like, like:
function func() {
echo global::$foo;
}
I've finally done it in this way.
Added a ServletContextListener that does the following:
public void contextInitialized(ServletContextEvent event) {
ServletContext context = event.getServletContext();
System.setProperty("rootPath", context.getRealPath("/"));
}
Then in the log4j.properties file:
log4j.appender.file.File=${rootPath}WEB-INF/logs/MyLog.log
By doing it in this way Log4j will write into the right folder as long as you don't use it before the "rootPath" system property has been set. This means that you cannot use it from the ServletContextListener itself but you should be able to use it from anywhere else in the app.
It should work on every web container and OS as it's not dependent on a container specific system property and it's not affected by OS specific path issues. Tested with Tomcat and Orion web containers and on Windows and Linux and it works fine so far.
What do you think?
There are two ways to display tabs at the bottom of a tab activity.
Please check the link for more details.
Actually, I came here with the same question as the creator of the topic, but none of the solutions given were a complete answer to my problem. Why adding a code to ALL the files on your server when you could simply configure it once ? The closest one was Residuum's one, but still, he was excluding ALL files, when I wanted to exclude only php files that weren't named index.php.
So I came up with a .htaccess containing this :
<Files *.php>
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</Files>
<Files index.php>
Order Allow,Deny
Allow from all
</Files>
(Remember, htaccess files are working recursively, so it suits perfectly the prerequisite of the question.)
And here we go. The only php files that will be accessible for an user will be the ones named index.php. But you can still acces to every image, css stylesheet, js script, etc.
An output reg foo
is just shorthand for output foo_wire; reg foo; assign foo_wire = foo
. It's handy when you plan to register that output anyway. I don't think input reg
is meaningful for module
(perhaps task
). input wire
and output wire
are the same as input
and output
: it's just more explicit.
You can also achieve this through aggregate pipeline.
db.collection.aggregate([{$sort:{age:-1}}, {$limit:1}])
Because Test discovery seems to be a complete subject, there is some dedicated framework to test discovery :

Note: Even though this is the accepted answer, the answer below is more accurate and is currently supported in all browsers if you have the option of using a background image.
No, there is no CSS only way to do this in both directions. You could add
.fillwidth {
min-width: 100%;
height: auto;
}
To the an element to always have it 100% width and automatically scale the height to the aspect ratio, or the inverse:
.fillheight {
min-height: 100%;
width: auto;
}
to always scale to max height and relative width. To do both, you will need to determine if the aspect ratio is higher or lower than it's container, and CSS can't do this.
The reason is that CSS does not know what the page looks like. It sets rules beforehand, but only after that it is that the elements get rendered and you know exactly what sizes and ratios you're dealing with. The only way to detect that is with JavaScript.
Although you're not looking for a JS solution I'll add one anyway if someone might need it. The easiest way to handle this with JavaScript is to add a class based on the difference in ratio. If the width-to-height ratio of the box is greater than that of the image, add the class "fillwidth", else add the class "fillheight".
$('div').each(function() {_x000D_
var fillClass = ($(this).height() > $(this).width()) _x000D_
? 'fillheight'_x000D_
: 'fillwidth';_x000D_
$(this).find('img').addClass(fillClass);_x000D_
});
_x000D_
.fillwidth { _x000D_
width: 100%; _x000D_
height: auto; _x000D_
}_x000D_
.fillheight { _x000D_
height: 100%; _x000D_
width: auto; _x000D_

$foobar = new foobar;
put the class foobar in $foobar, not the object. To get the object, you need to add parenthesis: $foobar = new foobar();
Your error is simply that you call a method on a class, so there is no $this
since $this
only exists in objects.
You haven't provided enough context to provide an accurate answer (i.e. how do you want to handle identical keys in multiple dicts?)
One answer is to iterate the list, and attempt to get 'd'
mylist = [{'a': 1, 'b': 2}, {'c': 3, 'd': 4}, {'e': 5, 'f': 6}]
myvalues = [i['d'] for i in mylist if 'd' in i]
Another answer is to access the dict directly (by list index), though you have to know that the key is present
mylist[1]['d']
I think you should try
data = {"shareInfo":[{"id":"1","a":"sss","b":"sss","question":"whi?"},
{"id":"2","a":"sss","b":"sss","question":"whi?"},
{"id":"3","a":"sss","b":"sss","question":"whi?"},
{"id":"4","a":"sss","b":"sss","question":"whi?"}]};
ShareInfoLength = data.shareInfo.length;
alert(ShareInfoLength);
for(var i=0; i<ShareInfoLength; i++)
{
alert(Object.keys(data.shareInfo[i]).length);
}

If you're using the HTML5 Fetch API to make POST requests as a logged in user and getting Forbidden (CSRF cookie not set.)
, it could be because by default fetch
does not include session cookies, resulting in Django thinking you're a different user than the one who loaded the page.
You can include the session token by passing the option credentials: 'include'
to fetch:
var csrftoken = getCookie('csrftoken');
var headers = new Headers();
headers.append('X-CSRFToken', csrftoken);
fetch('/api/upload', {
method: 'POST',
body: payload,
headers: headers,
credentials: 'include'
})
Just weighing in here with a nice solution I have been using. This is similar to Lucky Soni's solution above in that it supports aggregation, but doesn't require hard coding of the field names.
cursor = db.<collection_name>.<my_query_with_aggregation>;
headerPrinted = false;
while (cursor.hasNext()) {
item = cursor.next();
if (!headerPrinted) {
print(Object.keys(item).join(','));
headerPrinted = true;
}
line = Object
.keys(item)
.map(function(prop) {

print(line);

Save this as a .js
file, in this case we'll call it example.js
and run it with the mongo command line like so:
mongo <database_name> example.js --quiet > example.csv
I was able to solve the problem in my react native project by simply adding
configurations {
all*.exclude group: 'com.android.support', module: 'support-compat'
all*.exclude group: 'com.android.support', module: 'support-core-ui'
}
at the end of my android\app\build.gradle file
Everybody that using: var myVar = 'token', is probably the worst idea. I can print it dirrectly in the console. You need to encrypt on the client side, then decrypt on server side.
public class ListElementAdapter extends BaseAdapter{
String[] data;
Context context;
LayoutInflater layoutInflater;
public ListElementAdapter(String[] data, Context context) {
super();
this.data = data;
this.context = context;
layoutInflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
return data.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView= layoutInflater.inflate(R.layout.item, null);
TextView txt=(TextView)convertView.findViewById(R.id.text);
txt.setText(data[position]);
return convertView;
}
}
Just call ListElementAdapter in your Main Activity and set Adapter to ListView.
Single dimensional array decays to a pointer pointer pointing to the first element in the array. While a 2D array decays to a pointer pointing to first row. So, the function prototype should be -
void myFunction(double (*myArray) [10]);
I would prefer std::vector
over raw arrays.
You no need to edit php.ini
or any thing.
I suggest best thing as Just use MySQL WorkBench.
JUST FOLLOW THE STEPS.
Install MySQL WorkBench 6.0
And In "Navigation panel"(Left side) there is option call 'Data import' under "MANAGEMENT". Click that and [follow steps below]
"dump"[simple]
.You don't need a for loop in your code.
Here is how you can re implement your method
Edit:
Here is hint for you to proceed, Following code snippet gives int
values for char
s
System.out.println("a="+(int)'a');
System.out.println("z="+(int)'z');
System.out.println("A="+(int)'A');
System.out.println("Z="+(int)'Z');
Output
a=97
z=122
A=65
Z=90
Here is how you can check if a number x
exists between two numbers say a
and b
// x greater than or equal to a and x less than or equal to b
if ( x >= a && x <= b )
During comparisons char
s can be treated as numbers
If you can combine these hints, you should be able to find what you want ;)
import java.io.*;
class Initials {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s;
char x;
int l;
System.out.print("Enter any sentence: ");
s = br.readLine();
s = " " + s; //adding a space infront of the inputted sentence or a name
s = s.toUpperCase(); //converting the sentence into Upper Case (Capital Letters)
l = s.length(); //finding the length of the sentence
System.out.print("Output = ");
for (int i = 0; i < l; i++) {
x = s.charAt(i); //taking out one character at a time from the sentence
if (x == ' ') //if the character is a space, printing the next Character along with a fullstop
System.out.print(s.charAt(i + 1) + ".");
}
}
}
argmax()
will only return the first occurrence for each row.
http://docs.scipy.org/doc/numpy/reference/generated/numpy.argmax.html
If you ever need to do this for a shaped array, this works better than unravel
:
import numpy as np
a = np.array([[1,2,3], [4,3,1]]) # Can be of any shape
indices = np.where(a == a.max())
You can also change your conditions:
indices = np.where(a >= 1.5)
The above gives you results in the form that you asked for. Alternatively, you can convert to a list of x,y coordinates by:
x_y_coords = zip(indices[0], indices[1])
<textarea name="hide" style="display:none;"></textarea>
This sets the css display
property to none
, which prevents the browser from rendering the textarea.
That's a good problem. In order to solve that problem you will also have to disable ASLR otherwise the address of g() will be unpredictable.
Disable ASLR:
sudo bash -c 'echo 0 > /proc/sys/kernel/randomize_va_space'
Disable canaries:
gcc overflow.c -o overflow -fno-stack-protector
After canaries and ASLR are disabled it should be a straight forward attack like the ones described in Smashing the Stack for Fun and Profit
Here is a list of security features used in ubuntu: https://wiki.ubuntu.com/Security/Features You don't have to worry about NX bits, the address of g() will always be in a executable region of memory because it is within the TEXT memory segment. NX bits only come into play if you are trying to execute shellcode on the stack or heap, which is not required for this assignment.
Now go and clobber that EIP!
I personally like to create libs with extensions to the classes
public static List<TTo> Cast<TFrom, TTo>(List<TFrom> fromlist)
where TFrom : class
where TTo : class
{
return fromlist.ConvertAll(x => x as TTo);
}
Here's a really quick trick: Let's say you wanna add p tag inside div tag.
<div>
<p><script>document.write(<variablename>)</script></p>
</div>
And that's it.
I ran into this issue, and while it's true that ~/.npm
should be owned by your user, npm
was not installing the modules there.
What actually solved my issue is this command:
npm config set prefix ~/.npm
It will make sure that all your global installation will go under this prefix. And it's important that your user owns this directory.
You can use FileReader
to read the Blob
as an ArrayBuffer
.
Here's a short example:
var arrayBuffer;
var fileReader = new FileReader();
fileReader.onload = function(event) {
arrayBuffer = event.target.result;
};
fileReader.readAsArrayBuffer(blob);
Here's a longer example:
// ArrayBuffer -> Blob
var uint8Array = new Uint8Array([1, 2, 3]);
var arrayBuffer = uint8Array.buffer;
var blob = new Blob([arrayBuffer]);
// Blob -> ArrayBuffer
var uint8ArrayNew = null;
var arrayBufferNew = null;
var fileReader = new FileReader();
fileReader.onload = function(event) {
arrayBufferNew = event.target.result;
uint8ArrayNew = new Uint8Array(arrayBufferNew);
// warn if read values are not the same as the original values
// arrayEqual from: http://stackoverflow.com/questions/3115982/how-to-check-javascript-array-equals
function arrayEqual(a, b) { return !(a<b || b<a); };
if (arrayBufferNew.byteLength !== arrayBuffer.byteLength) // should be 3
console.warn("ArrayBuffer byteLength does not match");
if (arrayEqual(uint8ArrayNew, uint8Array) !== true) // should be [1,2,3]
console.warn("Uint8Array does not match");
};
fileReader.readAsArrayBuffer(blob);
fileReader.result; // also accessible this way once the blob has been read
This was tested out in the console of Chrome 27—69, Firefox 20—60, and Safari 6—11.
Here's also a live demonstration which you can play with: https://jsfiddle.net/potatosalad/FbaM6/
Update 2018-06-23: Thanks to Klaus Klein for the tip about event.target.result
versus this.result
Reference:
I used AutoIt to do it.
using AutoIt;
AutoItX.MouseClick("LEFT",150,150,1,0);//1: click once, 0: Move instantaneous
List is the preferred way in java 1.5 and beyond as it can use generics. Arrays cannot have generics. Also Arrays have a pre defined length, which cannot grow dynamically. Initializing an array with a large size is not a good idea. ArrayList is the the way to declare an array with generics and it can dynamically grow. But if delete and insert is used more frequently, then linked list is the fastest data structure to be used.
If you need to resume an scp transfer from local to remote, try with rsync:
rsync --partial --progress --rsh=ssh local_file user@host:remote_file
Short version, as pointed out by @aurelijus-rozenas:
rsync -P -e ssh local_file user@host:remote_file
In general the order of args for rsync is
rsync [options] SRC DEST
You need to include a declaration of the printf()
function.
#include <stdio.h>
i think you need to remove the ';' from the end of the java path.
strtok()
divides the string into tokens. i.e. starting from any one of the delimiter to next one would be your one token. In your case, the starting token will be from "-" and end with next space " ". Then next token will start from " " and end with ",". Here you get "This" as output. Similarly the rest of the string gets split into tokens from space to space and finally ending the last token on "."
git commit -a -m "Your commit message here"
will quickly commit all changes with the commit message. Git commit "title" and "description" (as you call them) are nothing more than just the first line, and the rest of the lines in the commit message, usually separated by a blank line, by convention. So using this command will just commit the "title" and no description.
If you want to commit a longer message, you can do that, but it depends on which shell you use.
In bash the quick way would be:
git commit -a -m $'Commit title\n\nRest of commit message...'
This worked for me. Give it a try:
cd ~/Library/Developer/Xcode/DerivedData
xattr -rc .
$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.
Passphrases can be added to an existing key or changed without regenerating the key pair:
Note This will work if keys doesn't had a passphrase, otherwise you'll get this: Enter old passphrase:
then Bad passphrase
$ ssh-keygen -p
Enter file in which the key is (/Users/tekkub/.ssh/id_rsa):
Key has comment '/Users/tekkub/.ssh/id_rsa'
Enter new passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved with the new passphrase.
If your key had passphrase
then, There's no way to recover the passphrase for a pair of SSH keys. In that case you have to create a new pair of SSH keys.
An alternative to the usual methods is to hook into the drawing of the view.
OnPreDrawListener
is called many times when displaying a view, so there is no specific iteration where your view has valid measured width or height. This requires that you continually verify (view.getMeasuredWidth() <= 0
) or set a limit to the number of times you check for a measuredWidth
greater than zero.
There is also a chance that the view will never be drawn, which may indicate other problems with your code.
final View view = [ACQUIRE REFERENCE]; // Must be declared final for inner class
ViewTreeObserver viewTreeObserver = view.getViewTreeObserver();
viewTreeObserver.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
@Override
public boolean onPreDraw() {
if (view.getMeasuredWidth() > 0) {
view.getViewTreeObserver().removeOnPreDrawListener(this);
int width = view.getMeasuredWidth();
int height = view.getMeasuredHeight();
//Do something with width and height here!
}
return true; // Continue with the draw pass, as not to stop it
}
});
arr = [1,9,5,2,4,9,5,8,7,9,0,8,2,7,5,8,0,2,9]
arr[rand(arr.count)]
This will return a random element from array.
If You will use the line mentioned below
arr[1+rand(arr.count)]
then in some cases it will return 0 or nil value.
The line mentioned below
rand(number)
always return the value from 0 to number-1.
If we use
1+rand(number)
then it may return number and arr[number] contains no element.
This seems more straightforward using data.table
as it performs the sort while setting the key.
So, if I were to get the top 3 records in sort (ascending order), then,
require(data.table)
d <- data.table(mtcars, key="cyl")
d[, head(.SD, 3), by=cyl]
does it.
And if you want the descending order
d[, tail(.SD, 3), by=cyl] # Thanks @MatthewDowle
Edit: To sort out ties using mpg
column:
d <- data.table(mtcars, key="cyl")
d.out <- d[, .SD[mpg %in% head(sort(unique(mpg)), 3)], by=cyl]
# cyl mpg disp hp drat wt qsec vs am gear carb rank
# 1: 4 22.8 108.0 93 3.85 2.320 18.61 1 1 4 1 11
# 2: 4 22.8 140.8 95 3.92 3.150 22.90 1 0 4 2 1
# 3: 4 21.5 120.1 97 3.70 2.465 20.01 1 0 3 1 8
# 4: 4 21.4 121.0 109 4.11 2.780 18.60 1 1 4 2 6
# 5: 6 18.1 225.0 105 2.76 3.460 20.22 1 0 3 1 7
# 6: 6 19.2 167.6 123 3.92 3.440 18.30 1 0 4 4 1
# 7: 6 17.8 167.6 123 3.92 3.440 18.90 1 0 4 4 2
# 8: 8 14.3 360.0 245 3.21 3.570 15.84 0 0 3 4 7
# 9: 8 10.4 472.0 205 2.93 5.250 17.98 0 0 3 4 14
# 10: 8 10.4 460.0 215 3.00 5.424 17.82 0 0 3 4 5
# 11: 8 13.3 350.0 245 3.73 3.840 15.41 0 0 3 4 3
# and for last N elements, of course it is straightforward
d.out <- d[, .SD[mpg %in% tail(sort(unique(mpg)), 3)], by=cyl]
For me Fake Sendmail works.
What to do:
1) Edit C:\wamp\sendmail\sendmail.ini:
smtp_server=smtp.gmail.com
smtp_port=465
[email protected]
auth_password=your_password
2) Edit php.ini
and set sendmail_path
sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"
That's it. Now you can test a mail.
I take it you're on Mac. See How can I install PIL on mac os x 10.7.2 Lion
If you use [homebrew][], you can install the PIL with just
brew install pil
. You may then need to add the install directory ($(brew --prefix)/lib/python2.7/site-packages
) to your PYTHONPATH, or add the location of PIL directory itself in a file calledPIL.pth
file in any of your site-packages directories, with the contents:/usr/local/lib/python2.7/site-packages/PIL
(assuming
brew --prefix
is/usr/local
).Alternatively, you can just download/build/install it from source:
# download curl -O -L http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz # extract tar -xzf Imaging-1.1.7.tar.gz cd Imaging-1.1.7 # build and install python setup.py build sudo python setup.py install # or install it for just you without requiring admin permissions: # python setup.py install --user
I ran the above just now (on OSX 10.7.2, with XCode 4.2.1 and System Python 2.7.1) and it built just fine, though there is a possibility that something in my environment is non-default.

Short answer: You can't.
Technically there is an accurate way, which would be checking the property:
history.previous
However, it won't work. The problem with this is that in most browsers this is considered a security violation and usually just returns undefined.
history.length
Is a property that others have suggested...
However, the length doesn't work completely because it doesn't indicate where in the history you are. Additionally, it doesn't always start at the same number. A browser not set to have a landing page, for example, starts at 0 while another browser that uses a landing page will start at 1.
Most of the time a link is added that calls:
history.back();
or
history.go(-1);
and it's just expected that if you can't go back then clicking the link does nothing.
This is a very fast and simple way who doesn't need complex solution.
let duration = String(format: "%.01f", 3.32323242)
// result = 3.3
paramstr.Remove((paramstr.Length-1),1);
This does work to remove a single character from the end of a string. But if I use it to remove, say, 4 characters, this doesn't work:
paramstr.Remove((paramstr.Length-4),1);
As an alternative, I have used this approach instead:
DateFrom = DateFrom.Substring(0, DateFrom.Length-4);
select TABLE_NAME from user_tables;
Above query will give you the names of all tables present in that user;
So try this out (x == true) ^ (x == false)
note you need the parenthesis but this is more beautiful and compact.
It even passes the suggested like "cuak" but not a "cuak"... class X; def !; self end end ; x = X.new; (x == true) ^ (x == false)
Note: See that this is so basic that you can use it in other languages too, that doesn't provide a "thing is boolean".
Note 2: Also you can use this to say thing is one of??: "red", "green", "blue"
if you add more XORS
... or say this thing is one of??: 4, 5, 8, 35
.
Assuming the following:
You can delete an Android Studio module as follows:
You can use playbook_dir
variable.
Be aware that some browser extensions can add code to the pages. In my case I had an "Emmet in all textareas" plugin that messed up with my requireJs. Make sure that no extra code is beign added to your document by inspecting it in the browser.
.grandparent{
display: table;
}
.parent{
display: table-cell
vertical-align: middle
}
This worked for me.
If you want to know if "1" ou 1 can be casted to a number, you can use this code :

Use jQuery.prototype.val
to get/set field values:
var value = $('#doc_title').val(); // get value
$('#doc_title').val(''); // clear value
ad 1. It does not implement its methods.
ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap
is an interface that extends Map
. A client not interested in the sorting aspect can code against Map
and handle all the instances of for example TreeMap
, which implements SortedMap
. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap
interface.
In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.
Use $http Interceptor
By using an $http interceptor you can send headers to Back-end or the other way around and do your checks that way.
Great article on $http interceptors
Example:
$httpProvider.interceptors.push(function ($q) {
return {
'response': function (response) {
// TODO Create check for user authentication. With every request send "headers" or do some other check
return response;
},
'responseError': function (reject) {
// Forbidden
if(reject.status == 403) {
console.log('This page is forbidden.');
window.location = '/';
// Unauthorized
} else if(reject.status == 401) {
console.log("You're not authorized to view this page.");
window.location = '/';
}
return $q.reject(reject);
}
};
});
Put this in your .config or .run function.
You're only getting the first line from the diamond operator <FILE>
because you're evaluating it in scalar context:
$document = <FILE>;
In list/array context, the diamond operator will return all the lines of the file.
@lines = <FILE>;
print @lines;
What happens in your code if $usertable
is not a valid table or doesn't include a column PartNumber or part is not a number.
You must escape $partid and also read the document for mysql_fetch_assoc() because it can return a boolean
I had a similar exception:
java.lang.SecurityException: class "org.hamcrest.Matchers"'s signer information does not match signer information of other classes in the same package
The root problem was that I included the Hamcrest library twice. Once using Maven pom file. And I also added the JUnit 4 library (which also contains a Hamcrest library) to the project's build path. I simply had to remove JUnit from the build path and everything was fine.
.click
events only work when element gets rendered and are only attached to elements loaded when the DOM is ready.
.on
events are dynamically attached to DOM elements, which is helpful when you want to attach an event to DOM elements that are rendered on ajax request or something else (after the DOM is ready).

If you really to assign values (as opposed to initialize), you can do it like this:
GLfloat coordinates[8];
static const GLfloat coordinates_defaults[8] = {1.0f, 0.0f, 1.0f ....};
...
memcpy(coordinates, coordinates_defaults, sizeof(coordinates_defaults));
return coordinates;
Here's an example of a context manager to change the working directory. It is simpler than an ActiveState version referred to elsewhere, but this gets the job done.
cd
import os
class cd:
"""Context manager for changing the current working directory"""
def __init__(self, newPath):
self.newPath = os.path.expanduser(newPath)
def __enter__(self):
self.savedPath = os.getcwd()
os.chdir(self.newPath)
def __exit__(self, etype, value, traceback):
os.chdir(self.savedPath)
Or try the more concise equivalent(below), using ContextManager.
import subprocess # just to call an arbitrary command e.g. 'ls'
# enter the directory like this:
with cd("~/Library"):
# we are in ~/Library
subprocess.call("ls")
# outside the context manager we are back wherever we started.
Yes, there are tons of them on regexlib. That only proves that RE's should not be used to do that. Use SGMLParser or BeautifulSoup or write a parser - but don't use RE's. The ones that seems to work are extremely compliated and still don't cover all cases.
There are two models for implementing classes and instances in JavaScript: the prototyping way, and the closure way. Both have advantages and drawbacks, and there are plenty of extended variations. Many programmers and libraries have different approaches and class-handling utility functions to paper over some of the uglier parts of the language.
The result is that in mixed company you will have a mishmash of metaclasses, all behaving slightly differently. What's worse, most JavaScript tutorial material is terrible and serves up some kind of in-between compromise to cover all bases, leaving you very confused. (Probably the author is also confused. JavaScript's object model is very different to most programming languages, and in many places straight-up badly designed.)
Let's start with the prototype way. This is the most JavaScript-native you can get: there is a minimum of overhead code and instanceof will work with instances of this kind of object.
function Shape(x, y) {
this.x= x;
this.y= y;
}
We can add methods to the instance created by new Shape
by writing them to the prototype
lookup of this constructor function:
Shape.prototype.toString= function() {
return 'Shape at '+this.x+', '+this.y;
};
Now to subclass it, in as much as you can call what JavaScript does subclassing. We do that by completely replacing that weird magic prototype
property:
function Circle(x, y, r) {
Shape.call(this, x, y); // invoke the base class's constructor function to take co-ords
this.r= r;
}
Circle.prototype= new Shape();
before adding methods to it:
Circle.prototype.toString= function() {
return 'Circular '+Shape.prototype.toString.call(this)+' with radius '+this.r;
}
This example will work and you will see code like it in many tutorials. But man, that new Shape()
is ugly: we're instantiating the base class even though no actual Shape is to be created. It happens to work in this simple case because JavaScript is so sloppy: it allows zero arguments to be passed in, in which case x
and y
become undefined
and are assigned to the prototype's this.x
and this.y
. If the constructor function were doing anything more complicated, it would fall flat on its face.
So what we need to do is find a way to create a prototype object which contains the methods and other members we want at a class level, without calling the base class's constructor function. To do this we are going to have to start writing helper code. This is the simplest approach I know of:
function subclassOf(base) {
_subclassOf.prototype= base.prototype;
return new _subclassOf();
}
function _subclassOf() {};
This transfers the base class's members in its prototype to a new constructor function which does nothing, then uses that constructor. Now we can write simply:
function Circle(x, y, r) {
Shape.call(this, x, y);
this.r= r;
}
Circle.prototype= subclassOf(Shape);
instead of the new Shape()
wrongness. We now have an acceptable set of primitives to built classes.
There are a few refinements and extensions we can consider under this model. For example here is a syntactical-sugar version:
Function.prototype.subclass= function(base) {
var c= Function.prototype.subclass.nonconstructor;
c.prototype= base.prototype;
this.prototype= new c();
};
Function.prototype.subclass.nonconstructor= function() {};
...
function Circle(x, y, r) {
Shape.call(this, x, y);
this.r= r;
}
Circle.subclass(Shape);
Either version has the drawback that the constructor function cannot be inherited, as it is in many languages. So even if your subclass adds nothing to the construction process, it must remember to call the base constructor with whatever arguments the base wanted. This can be slightly automated using apply
, but still you have to write out:
function Point() {
Shape.apply(this, arguments);
}
Point.subclass(Shape);
So a common extension is to break out the initialisation stuff into its own function rather than the constructor itself. This function can then inherit from the base just fine:
function Shape() { this._init.apply(this, arguments); }
Shape.prototype._init= function(x, y) {
this.x= x;
this.y= y;
};
function Point() { this._init.apply(this, arguments); }
Point.subclass(Shape);
// no need to write new initialiser for Point!
Now we've just got the same constructor function boilerplate for each class. Maybe we can move that out into its own helper function so we don't have to keep typing it, for example instead of Function.prototype.subclass
, turning it round and letting the base class's Function spit out subclasses:
Function.prototype.makeSubclass= function() {
function Class() {
if ('_init' in this)
this._init.apply(this, arguments);
}
Function.prototype.makeSubclass.nonconstructor.prototype= this.prototype;
Class.prototype= new Function.prototype.makeSubclass.nonconstructor();
return Class;
};
Function.prototype.makeSubclass.nonconstructor= function() {};
...
Shape= Object.makeSubclass();
Shape.prototype._init= function(x, y) {
this.x= x;
this.y= y;
};
Point= Shape.makeSubclass();
Circle= Shape.makeSubclass();
Circle.prototype._init= function(x, y, r) {
Shape.prototype._init.call(this, x, y);
this.r= r;
};
...which is starting to look a bit more like other languages, albeit with slightly clumsier syntax. You can sprinkle in a few extra features if you like. Maybe you want makeSubclass
to take and remember a class name and provide a default toString
using it. Maybe you want to make the constructor detect when it has accidentally been called without the new
operator (which would otherwise often result in very annoying debugging):
Function.prototype.makeSubclass= function() {
function Class() {
if (!(this instanceof Class))
throw('Constructor called without "new"');
...
Maybe you want to pass in all the new members and have makeSubclass
add them to the prototype, to save you having to write Class.prototype...
quite so much. A lot of class systems do that, eg:
Circle= Shape.makeSubclass({
_init: function(x, y, z) {
Shape.prototype._init.call(this, x, y);
this.r= r;
},
...
});
There are a lot of potential features you might consider desirable in an object system and no-one really agrees on one particular formula.
The closure way, then. This avoids the problems of JavaScript's prototype-based inheritance, by not using inheritance at all. Instead:
function Shape(x, y) {
var that= this;
this.x= x;
this.y= y;
this.toString= function() {
return 'Shape at '+that.x+', '+that.y;
};
}
function Circle(x, y, r) {
var that= this;
Shape.call(this, x, y);
this.r= r;
var _baseToString= this.toString;
this.toString= function() {
return 'Circular '+_baseToString(that)+' with radius '+that.r;
};
};
var mycircle= new Circle();
Now every single instance of Shape
will have its own copy of the toString
method (and any other methods or other class members we add).
The bad thing about every instance having its own copy of each class member is that it's less efficient. If you are dealing with large numbers of subclassed instances, prototypical inheritance may serve you better. Also calling a method of the base class is slightly annoying as you can see: we have to remember what the method was before the subclass constructor overwrote it, or it gets lost.
[Also because there is no inheritance here, the instanceof
operator won't work; you would have to provide your own mechanism for class-sniffing if you need it. Whilst you could fiddle the prototype objects in a similar way as with prototype inheritance, it's a bit tricky and not really worth it just to get instanceof
working.]
The good thing about every instance having its own method is that the method may then be bound to the specific instance that owns it. This is useful because of JavaScript's weird way of binding this
in method calls, which has the upshot that if you detach a method from its owner:
var ts= mycircle.toString;
alert(ts());
then this
inside the method won't be the Circle instance as expected (it'll actually be the global window
object, causing widespread debugging woe). In reality this typically happens when a method is taken and assigned to a setTimeout
, onclick
or EventListener
in general.
With the prototype way, you have to include a closure for every such assignment:
setTimeout(function() {
mycircle.move(1, 1);
}, 1000);
or, in the future (or now if you hack Function.prototype) you can also do it with function.bind()
:
setTimeout(mycircle.move.bind(mycircle, 1, 1), 1000);
if your instances are done the closure way, the binding is done for free by the closure over the instance variable (usually called that
or self
, though personally I would advise against the latter as self
already has another, different meaning in JavaScript). You don't get the arguments 1, 1
in the above snippet for free though, so you would still need another closure or a bind()
if you need to do that.
There are lots of variants on the closure method too. You may prefer to omit this
completely, creating a new that
and returning it instead of using the new
operator:
function Shape(x, y) {
var that= {};
that.x= x;
that.y= y;
that.toString= function() {
return 'Shape at '+that.x+', '+that.y;
};
return that;
}
function Circle(x, y, r) {
var that= Shape(x, y);
that.r= r;
var _baseToString= that.toString;
that.toString= function() {
return 'Circular '+_baseToString(that)+' with radius '+r;
};
return that;
};
var mycircle= Circle(); // you can include `new` if you want but it won't do anything
Which way is “proper”? Both. Which is “best”? That depends on your situation. FWIW I tend towards prototyping for real JavaScript inheritance when I'm doing strongly OO stuff, and closures for simple throwaway page effects.
But both ways are quite counter-intuitive to most programmers. Both have many potential messy variations. You will meet both (as well as many in-between and generally broken schemes) if you use other people's code/libraries. There is no one generally-accepted answer. Welcome to the wonderful world of JavaScript objects.

You are using wrong formatting sequence for double

instead of %ld
:
double a;
scanf("%lf",&a);
C++ has proper strings so you might as well use them. They're in the standard header string. #include <string> to use them. No more strcat/strcpy buffer overruns; no more missing null terminators; no more messy manual memory management; proper counted strings with proper value semantics.
C++ has the ability to convert bools into human-readable representations too. We saw hints at it earlier with the iostream examples, but they're a bit limited because they can only blast the text to the console (or with fstreams, a file). Fortunately, the designers of C++ weren't complete idiots; we also have iostreams that are backed not by the console or a file, but by an automatically managed string buffer. They're called stringstreams. #include <sstream> to get them. Then we can say:
std::string bool_as_text(bool b)
{
std::stringstream converter;
converter << std::boolalpha << b; // flag boolalpha calls converter.setf(std::ios_base::boolalpha)
return converter.str();
}
Of course, we don't really want to type all that. Fortunately, C++ also has a convenient third-party library named Boost that can help us out here. Boost has a nice function called lexical_cast. We can use it thus:
boost::lexical_cast<std::string>(my_bool)
Now, it's true to say that this is higher overhead than some macro; stringstreams deal with locales which you might not care about, and create a dynamic string (with memory allocation) whereas the macro can yield a literal string, which avoids that. But on the flip side, the stringstream method can be used for a great many conversions between printable and internal representations. You can run 'em backwards; boost::lexical_cast<bool>("true") does the right thing, for example. You can use them with numbers and in fact any type with the right formatted I/O operators. So they're quite versatile and useful.
And if after all this your profiling and benchmarking reveals that the lexical_casts are an unacceptable bottleneck, that's when you should consider doing some macro horror.

As @osknows said in a comment above (rather than an answer which is why I am adding this), the Analysis Pack includes Random Number Generation functions (e.g. NORM.DIST

You can pass in the data to be used in the mouseover like this- the mouseover event uses a function with your previously enter
ed data as an argument (and the index as a second argument) so you don't need to use enter()
a second time.
vis.selectAll("circle")
.data(datafiltered).enter().append("svg:circle")
.attr("cx", function(d) { return x(d.x);})
.attr("cy", function(d) {return y(d.y)})
.attr("fill", "red").attr("r", 15)
.on("mouseover", function(d,i) {
d3.select(this).append("text")
.text( d.x)
.attr("x", x(d.x))
.attr("y", y(d.y));

Since Docker 1.5 you can now expose a range of ports to other linked containers using:
The Dockerfile EXPOSE command:
EXPOSE 7000-8000
or The Docker run command:
docker run --expose=7000-8000
Or instead you can publish a range of ports to the host machine via Docker run command:
docker run -p 7000-8000:7000-8000
`Display
$('#cbxShowHide').click(function(){ this.checked?$('#block').show(1000):$('#block').hide(1000); //time for show });`
You install as assemblies by using:
gacutil.exe
tool with the -i
option from the command line.%windir%\Assembly
(only up to .NET 3.5, CLR 2.0)You view the content of the GAC using:
gacutil.exe
tool with the -l
option.%windir%\assembly
using the Windows Explorer.Note that the (physical) GAC location has changed for .NET 4.0. It is no longer in %windir%\Assembly
, but now in %windir%\Microsoft.NET\assembly
. However, you should never write any code that depends on the physical location anyway, because given the tools available that is hardly necessary (some "cool" homegrown system diagnostics tools aside).
For react version 16.6.3, we use super(props) to initialize state element name : this.props.name
constructor(props){
super(props);
}
state = {
name:this.props.name
//otherwise not defined
};
As gengkev alludes to in his comment above, it looks like the best/only way to do this is with an async xhr2 call:
var xhr = new XMLHttpRequest();
xhr.open('GET', 'blob:http%3A//your.blob.url.here', true);
xhr.responseType = 'blob';
xhr.onload = function(e) {
if (this.status == 200) {
var myBlob = this.response;
// myBlob is now the blob that the object URL pointed to.
}
};
xhr.send();
Update (2018): For situations where ES5 can safely be used, Joe has a simpler ES5-based answer below.
For me works fine:
@RequestMapping (value = "/{id}", method = RequestMethod.GET)
public ResponseEntity<Object> redirectToExternalUrl() throws URISyntaxException {
URI uri = new URI("http://www.google.com");
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.setLocation(uri);
return new ResponseEntity<>(httpHeaders, HttpStatus.SEE_OTHER);
}
Delete the public keys and generate new ones from the private keys. Keep them in separate directories, or use a naming convention to keep them straight.

If you want to break your line because of a long literal string, you can break that string into pieces:
long_string = "a very long string"
print("a very long string")
will be replaced by
long_string = (
"a "
"very "
"long "
"string"
)
print(
"a "
"very "
"long "
"string"
)
Output for both print statements:
a very long string
Notice the parenthesis in the affectation.
Notice also that breaking literal strings into pieces allows to use the literal prefix only on parts of the string and mix the delimiters:
s = (
'''2+2='''
f"{2+2}"
)
Well I would do it like this instead:
TimeSpan diff = expiryDate - DateTime.Today;
if (diff.Days > 30)
matchFound = true;

The detach/copy/attach method will take down the database. That's not something you'd want in production.
The backup/restore will only work if you have write permissions to the production server. I work with Amazon RDS and I don't.
The import/export method doesn't really work because of foreign keys - unless you do tables one by one in the order they reference one another. You can do an import/export to a new database. That will copy all the tables and data, but not the foreign keys.
This sounds like a common operation one needs to do with database. Why isn't SQL Server handling this properly? Every time I had to do this it was frustrating.
That being said, the only painless solution I've encountered was Sql Azure Migration Tool which is maintained by the community. It works with SQL Server too.
IMHO the only 100% reliable way to test if you can write to a directory is to actually write to it and eventually catch exceptions.
I defined two functions in Site.Master:
<script type="text/javascript">
var spinnerVisible = false;
function showProgress() {
if (!spinnerVisible) {
$("div#spinner").fadeIn("fast");
spinnerVisible = true;
}
};
function hideProgress() {
if (spinnerVisible) {
var spinner = $("div#spinner");
spinner.stop();
spinner.fadeOut("fast");
spinnerVisible = false;
}
};
</script>
And special section:
<div id="spinner">
Loading...
</div>
Visual style is defined in CSS:
div#spinner
{
display: none;
width:100px;
height: 100px;
position: fixed;
top: 50%;
left: 50%;
background:url(spinner.gif) no-repeat center #fff;
text-align:center;
padding:10px;
font:normal 16px Tahoma, Geneva, sans-serif;
border:1px solid #666;
margin-left: -50px;
margin-top: -50px;
z-index:2;
overflow: auto;
}
Here's a small example to demonstrate this (which only applied to DataFrames, not Series, until Pandas 0.19 where it applies to both):
In [1]: df1 = pd.DataFrame([[1, 2], [3, 4]])
In [2]: df2 = pd.DataFrame([[3, 4], [1, 2]], index=[1, 0])
In [3]: df1 == df2
Exception: Can only compare identically-labeled DataFrame objects
One solution is to sort the index first (Note: some functions require sorted indexes):
In [4]: df2.sort_index(inplace=True)
In [5]: df1 == df2
Out[5]:
0 1
0 True True
1 True True
Note: ==
is also sensitive to the order of columns, so you may have to use sort_index(axis=1)
:
In [11]: df1.sort_index().sort_index(axis=1) == df2.sort_index().sort_index(axis=1)
Out[11]:
0 1
0 True True
1 True True
Note: This can still raise (if the index/columns aren't identically labelled after sorting).
In addition to the answer given by @l0b0 I just had the situation where I needed to both keep any trailing newlines output by the script and check the script's return code. And the problem with l0b0's answer is that the 'echo x' was resetting $? back to zero... so I managed to come up with this very cunning solution:
RESULTX="$(./myscript; echo x$?)"
RETURNCODE=${RESULTX##*x}
RESULT="${RESULTX%x*}"
Merge byte arrays of multiple PDF files:
public static byte[] MergePDFs(List<byte[]> pdfFiles)
{
if (pdfFiles.Count > 1)
{
PdfReader finalPdf;
Document pdfContainer;
PdfWriter pdfCopy;
MemoryStream msFinalPdf = new MemoryStream();
finalPdf = new PdfReader(pdfFiles[0]);
pdfContainer = new Document();
pdfCopy = new PdfSmartCopy(pdfContainer, msFinalPdf);
pdfContainer.Open();
for (int k = 0; k < pdfFiles.Count; k++)
{
finalPdf = new PdfReader(pdfFiles[k]);
for (int i = 1; i < finalPdf.NumberOfPages + 1; i++)
{
((PdfSmartCopy)pdfCopy).AddPage(pdfCopy.GetImportedPage(finalPdf, i));
}
pdfCopy.FreeReader(finalPdf);
}
finalPdf.Close();
pdfCopy.Close();
pdfContainer.Close();
return msFinalPdf.ToArray();
}
else if (pdfFiles.Count == 1)
{
return pdfFiles[0];
}
return null;
}
In case of a very large stream length there is the hazard of memory leak due to Large Object Heap. i.e. The byte buffer created by stream.ToArray creates a copy of memory stream in Heap memory leading to duplication of reserved memory. I would suggest to use a StreamReader
, a TextWriter
and read the stream in chunks of char
buffers.
In netstandard2.0 System.IO.StreamReader
has a method ReadBlock
you can use this method in order to read the instance of a Stream (a MemoryStream instance as well since Stream is the super of MemoryStream):
private static string ReadStreamInChunks(Stream stream, int chunkLength)
{
stream.Seek(0, SeekOrigin.Begin);
string result;
using(var textWriter = new StringWriter())
using (var reader = new StreamReader(stream))
{
var readChunk = new char[chunkLength];
int readChunkLength;
//do while: is useful for the last iteration in case readChunkLength < chunkLength
do
{
readChunkLength = reader.ReadBlock(readChunk, 0, chunkLength);
textWriter.Write(readChunk,0,readChunkLength);
} while (readChunkLength > 0);
result = textWriter.ToString();
}
return result;
}
NB. The hazard of memory leak is not fully eradicated, due to the usage of MemoryStream, that can lead to memory leak for large memory stream instance (memoryStreamInstance.Size >85000 bytes). You can use Recyclable Memory stream, in order to avoid LOH. This is the relevant library

Paul's answer is the one you're looking for. However, as a practical matter, I think you may be interested in the pattern I've been using in my own React+Redux apps.
Here's a stripped-down example from one of my routes, showing how you can define your component and export it as default with a single statement:
import React from 'react';
import { connect } from 'react-redux';
@connect((state, props) => ({
appVersion: state.appVersion
// other scene props, calculated from app state & route props
}))
export default class SceneName extends React.Component { /* ... */ }
(Note: I use the term "Scene" for the top-level component of any route).
I hope this is helpful. I think it's much cleaner-looking than the conventional connect( mapState, mapDispatch )( BareComponent )
You can simply use the zoom property:
#myContainer{
zoom: 0.5;
-moz-transform: scale(0.5);
}
Where myContainer contains all the elements you're editing. This is supported in all major browsers.
The type char is a primitive -- not an object -- so it cannot be dereferenced
Dereferencing is the process of accessing the value referred to by a reference. Since a char is already a value (not a reference), it can not be dereferenced.
use Character
class:
if(Character.isLetter(c)) {
Use InvariantCulture. The decimal separator is always "." eventually you can replace "," by "." When you display the result , use your local culture. But internally use always invariant culture
TryParse does not allway work as we would expect There are change request in .net in this area:
If you will not be needing the _id of the records I will recommend unsetting it when querying the DB which will enable you to print the returned records directly e.g
To unset the _id when querying and then print data in a loop you write something like this
records = mycollection.find(query, {'_id': 0}) #second argument {'_id':0} unsets the id from the query
for record in records:
print(record)

You can access characters in strings in the same way as you would access an array index, e.g.
$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
$thisWordCodeVerdeeld[$i] = $string[$i];
}
You could also do:
$thisWordCodeVerdeeld = str_split($string);
However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.
Since my Edit on the above post by thevangelist wasn't approved, posting additional information.
If you want to pick value from package.json like a defined version number and access it through DefinePlugin inside Javascript.
{"version": "0.0.1"}
Then, Import package.json inside respective webpack.config, access the attribute using the import variable, then use the attribute in the DefinePlugin.
const PACKAGE = require('../package.json');
const _version = PACKAGE.version;//Picks the version number from package.json
For example certain configuration on webpack.config is using METADATA for DefinePlugin:
const METADATA = webpackMerge(commonConfig({env: ENV}).metadata, {
host: HOST,
port: PORT,
ENV: ENV,
HMR: HMR,
RELEASE_VERSION:_version//Version attribute retrieved from package.json
});
new DefinePlugin({
'ENV': JSON.stringify(METADATA.ENV),
'HMR': METADATA.HMR,
'process.env': {
'ENV': JSON.stringify(METADATA.ENV),
'NODE_ENV': JSON.stringify(METADATA.ENV),
'HMR': METADATA.HMR,
'VERSION': JSON.stringify(METADATA.RELEASE_VERSION)//Setting it for the Scripts usage.
}
}),
Access this inside any typescript file:
this.versionNumber = process.env.VERSION;
The smartest way would be like this:
// webpack.config.js
plugins: [
new webpack.DefinePlugin({
VERSION: JSON.stringify(require("./package.json").version)
})
]
In Jackson 2.x, use:
@JsonInclude(JsonInclude.Include.NON_NULL)
Os X Mojave 10.14 has:
Error: The Command Line Tools header package must be installed on Mojave.
Solution. Go to
/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
location and install the package manually. And brew will start working and we can run:
brew uninstall --force git
brew cleanup --force -s git
brew prune
brew install git
You can also use insertAdjacentHTML
function:
const select = document.querySelector('select')
const value = 'bmw'
const label = 'BMW'
select.insertAdjacentHTML('beforeend', `
<option value="${value}">${label}</option>
`)
A generic solution that will work with any testing framework (if your class is non-final
) is to manually create your own mock.
This doesn't use any framework so its not as elegant but it will always work: even without PowerMock. Alternatively, you can use Mockito to do steps #2 & #3 for you, if you've done step #1 already.
To mock a private method directly, you'll need to use PowerMock as shown in the other answer.
Use sorted TreeMap
:
Map<String, Float> map = new TreeMap<>(yourMap);
It will automatically put entries sorted by keys. I think natural String
ordering will be fine in your case.
Note that HashMap
due to lookup optimizations does not preserve order.
Wow, you have a huge misunderstanding how asp.net works.
This line of code
System.Diagnostics.Process.Start("help/AdminTutorial.html");
Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.
A very easy solution would be to change the href attribute of the link in you page_load method.
Your aspx code:
<a href="#" runat="server" id="myLink">Tutorial</a>
Your codebehind / cs code of page_load:
...
if (userinfo.user == "Admin")
{
myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else
{
myLink.Attributes["href"] = "help/otherSite.html";
}
...
Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.
Actually, this has nothing to do with the usual Windows / Unix \r\n
vs \n
issue. The TELNET procotol itself defines \r\n
as the end-of-line sequence, independently of the operating system. See RFC854.
Yes, there is a difference;
throw ex
resets the stack trace (so your errors would appear to originate from HandleException
)throw
doesn't - the original offender would be preserved.
static void Main(string[] args)
{
try
{
Method2();
}
catch (Exception ex)
{
Console.Write(ex.StackTrace.ToString());
Console.ReadKey();
}
}
private static void Method2()
{
try
{
Method1();
}
catch (Exception ex)
{
//throw ex resets the stack trace Coming from Method 1 and propogates it to the caller(Main)
throw ex;
}
}
private static void Method1()
{
try
{
throw new Exception("Inside Method1");
}
catch (Exception)
{
throw;
}
}
You may have imported,
project/controllers/base
inside the
project/controllers/routes
You have already imported before. That's not supported.
You can use instanceof
.
instanceof
RelationalExpression: RelationalExpression instanceof ReferenceType
At run time, the result of the
instanceof
operator istrue
if the value of the RelationalExpression is notnull
and the reference could be cast to the ReferenceType without raising aClassCastException
. Otherwise the result isfalse
.
That means you can do something like this:
Object o = new int[] { 1,2 };
System.out.println(o instanceof int[]); // prints "true"
You'd have to check if the object is an instanceof boolean[]
, byte[]
, short[]
, char[]
, int[]
, long[]
, float[]
, double[]
, or Object[]
, if you want to detect all array types.
Also, an int[][]
is an instanceof Object[]
, so depending on how you want to handle nested arrays, it can get complicated.
For the toString
, java.util.Arrays
has a toString(int[])
and other overloads you can use. It also has deepToString(Object[])
for nested arrays.
public String toString(Object arr) {
if (arr instanceof int[]) {
return Arrays.toString((int[]) arr);
} else //...
}
It's going to be very repetitive (but even java.util.Arrays
is very repetitive), but that's the way it is in Java with arrays.
If your project already depends on Apache Commons you can use StringUtils.ordinalIndexOf
, otherwise, here's an implementation:
public static int ordinalIndexOf(String str, String substr, int n) {
int pos = str.indexOf(substr);
while (--n > 0 && pos != -1)
pos = str.indexOf(substr, pos + 1);
return pos;
}

I would recommend that you use the following code in CSS:
text-transform:uppercase;
Make sure you put it in your class.
In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.
The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly
property of a type found in the assembly.
The following example illustrates:
using System;
using System.Reflection;
public class Example
{
public static void Main()
{
Console.WriteLine("The version of the currently executing assembly is: {0}",
typeof(Example).Assembly.GetName().Version);
}
}
/* This example produces output similar to the following:
The version of the currently executing assembly is: 1.1.0.0
Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.
Try below block of code, its working for me.
char *p = "0x820";
uint16_t intVal;
sscanf(p, "%x", &intVal);
printf("value x: %x - %d", intVal, intVal);
Output is:
value x: 820 - 2080
I would recommend you to change Status cache of the Overlays.
Settings -> Icon Overlays -> Status cache
Maybe this would help to reinitialise the cache.
Be sure touse the latest version of Tortoise.
How about the standard procedure:
git add folder
git commit
This will add the folder and all it's files with a single command.
Please note, git is not able to store empty folders.
If commit didn't worked, the first place you should check is probably .gitignore
.
In OSX, you can set the classpath from scratch like this:
export CLASSPATH=/path/to/some.jar:/path/to/some/other.jar
Or you can add to the existing classpath like this:
export CLASSPATH=$CLASSPATH:/path/to/some.jar:/path/to/some/other.jar
This is answering your exact question, I'm not saying it's the right or wrong thing to do; I'll leave that for others to comment upon.
Some people don't know about this. You can apply it on div:hover
and working on iPhone .
Add the following css to the element with :hover
effect
.mm {
cursor: pointer;
}
list = new List<ProcedureTime>(); sortedList = list.OrderByDescending(ProcedureTime=> ProcedureTime.EndTime).ToList();
Which works for me to show the time sorted in descending order.
There is a lot of confusion and misinformation regarding the while;pop/shift performance both in answers and comments. The while/pop solution has (as expected) the worst performance. What's actually happening is that setup runs only once for each sample that runs the snippet in a loop. eg:
var arr = [];
for (var i = 0; i < 100; i++) {
arr.push(Math.random());
}
for (var j = 0; j < 1000; j++) {
while (arr.length > 0) {
arr.pop(); // this executes 100 times, not 100000
}
}
I have created a new test that works correctly :
http://jsperf.com/empty-javascript-array-redux
Warning: even in this version of the test you can't actually see the real difference because cloning the array takes up most of the test time. It still shows that splice
is the fastest way to clear the array (not taking []
into consideration because while it is the fastest it's not actually clearing the existing array).
Have you tried to set the value of the static DefaultConnectionLimit property programmatically?
Here is a good source of information about that true headache... ASP.NET Thread Usage on IIS 7.5, IIS 7.0, and IIS 6.0, with updates for framework 4.0.
instead of clearing the name text use placeholder attribute it is good practice
<input type="text" placeholder="name" name="name">
So actually the problem is that SMTP.sendmail and email.MIMEText need two different things.
email.MIMEText sets up the "To:" header for the body of the e-mail. It is ONLY used for displaying a result to the human being at the other end, and like all e-mail headers, must be a single string. (Note that it does not actually have to have anything to do with the people who actually receive the message.)
SMTP.sendmail, on the other hand, sets up the "envelope" of the message for the SMTP protocol. It needs a Python list of strings, each of which has a single address.
So, what you need to do is COMBINE the two replies you received. Set msg['To'] to a single string, but pass the raw list to sendmail:
emails = ['a.com','b.com', 'c.com']
msg['To'] = ', '.join( emails )
....
s.sendmail( msg['From'], emails, msg.as_string())
For New way we have registerForActivityResult
In Java :
// You need to create lanucher variable inside onAttach or onCreate or global, i.e, before the activity is displayed
ActivityResultLauncher<Intent> launchSomeActivity = registerForActivityResult(
new ActivityResultContracts.StartActivityForResult(),
new ActivityResultCallback<ActivityResult>() {
@Override
public void onActivityResult(ActivityResult result) {
if (result.getResultCode() == Activity.RESULT_OK) {
Intent data = result.getData();
// your operation....
}
}
});
public void openYourActivity() {
Intent intent = new Intent(this, SomeActivity.class);
launchSomeActivity.launch(intent);
}
In Kotlin :
var resultLauncher = registerForActivityResult(StartActivityForResult()) { result ->
if (result.resultCode == Activity.RESULT_OK) {
val data: Intent? = result.data
// your operation...
}
}
fun openYourActivity() {
val intent = Intent(this, SomeActivity::class.java)
resultLauncher.launch(intent)
}
New way is reduce complexity which we faced when we call activity from fragment or from another activity
From the numpy.polyfit documentation, it is fitting linear regression. Specifically, numpy.polyfit with degree 'd' fits a linear regression with the mean function
E(y|x) = p_d * x**d + p_{d-1} * x **(d-1) + ... + p_1 * x + p_0
So you just need to calculate the R-squared for that fit. The wikipedia page on linear regression gives full details. You are interested in R^2 which you can calculate in a couple of ways, the easisest probably being
SST = Sum(i=1..n) (y_i - y_bar)^2
SSReg = Sum(i=1..n) (y_ihat - y_bar)^2
Rsquared = SSReg/SST
Where I use 'y_bar' for the mean of the y's, and 'y_ihat' to be the fit value for each point.
I'm not terribly familiar with numpy (I usually work in R), so there is probably a tidier way to calculate your R-squared, but the following should be correct
import numpy
# Polynomial Regression
def polyfit(x, y, degree):
results = {}
coeffs = numpy.polyfit(x, y, degree)
# Polynomial Coefficients
results['polynomial'] = coeffs.tolist()
# r-squared
p = numpy.poly1d(coeffs)
# fit values, and mean
yhat = p(x) # or [p(z) for z in x]
ybar = numpy.sum(y)/len(y) # or sum(y)/len(y)
ssreg = numpy.sum((yhat-ybar)**2) # or sum([ (yihat - ybar)**2 for yihat in yhat])
sstot = numpy.sum((y - ybar)**2) # or sum([ (yi - ybar)**2 for yi in y])
results['determination'] = ssreg / sstot
return results
getCurrentActivity() is also in ReactContextBaseJavaModule.
(Since the this question was initially asked, many Android app also has ReactNative component - hybrid app.)
class ReactContext in ReactNative has the whole set of logic to maintain mCurrentActivity which is returned in getCurrentActivity().
Note: I wish getCurrentActivity() is implemented in Android Application class.
I use jQuery BeautyTips to achieve the little bubble effect you are talking about. I don't use the Validation plugin so I can't really help much there, but it is very easy to style and show the BeautyTips. You should look into it. It's not as simple as just CSS rules, I'm afraid, as you need to use the canvas element and include an extra javascript file for IE to play nice with it.

No, you can't make the img stretch to fit the div and simultaneously achieve the inverse. You would have an infinite resizing loop. However, you could take some notes from other answers and implement some min and max dimensions but that wasn't the question.
You need to decide if your image will scale to fit its parent or if you want the div to expand to fit its child img.
Using this block tells me you want the image size to be variable so the parent div is the width an image scales to. height: auto
is going to keep your image aspect ratio in tact. if you want to stretch the height it needs to be 100%
like this fiddle.
img {
width: 100%;
height: auto;
}
When doing;
a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')
...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.
Your other example though;
a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
should work well if you just have the permission on a.txt
. You may want to use a raw (r
-prefixed) string though, to make sure your path does not contain any escape characters like \n
that will be translated to special characters.
a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
My full example is here, but I will provide a summary below.
Layout
Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).
Make the swift file the xib file's owner.
Add the following code to the .swift file and hook up the outlets and actions from the .xib file.
import UIKit
class ResuableCustomView: UIView {
let nibName = "ReusableCustomView"
var contentView: UIView?
@IBOutlet weak var label: UILabel!
@IBAction func buttonTap(_ sender: UIButton) {
label.text = "Hi"
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
guard let view = loadViewFromNib() else { return }
view.frame = self.bounds
self.addSubview(view)
contentView = view
}
func loadViewFromNib() -> UIView? {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: nibName, bundle: bundle)
return nib.instantiate(withOwner: self, options: nil).first as? UIView
}
}
Use it
Use your custom view anywhere in your storyboard. Just add a UIView
and set the class name to your custom class name.
For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.
MyCustomClass.swift
MyCustomClass.xib
File's Owner
of the .xib file to be your custom class (MyCustomClass
)class
value (under the identity Inspector
) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.Assistant Editor
.
Connections Inspector
you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass
), but rather reference File's Owner
. Since File's Owner
is specified to be your custom class, the outlets will hook up and work propery. NibLoadable
protocol referenced below.
.swift
file name is different from your .xib
file name, then set the nibName
property to be the name of your .xib
file.required init?(coder aDecoder: NSCoder)
and override init(frame: CGRect)
to call setupFromNib()
like the example below.MyCustomClass
).Here is the protocol you will want to reference:
public protocol NibLoadable {
static var nibName: String { get }
}
public extension NibLoadable where Self: UIView {
public static var nibName: String {
return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
}
public static var nib: UINib {
let bundle = Bundle(for: Self.self)
return UINib(nibName: Self.nibName, bundle: bundle)
}
func setupFromNib() {
guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
addSubview(view)
view.translatesAutoresizingMaskIntoConstraints = false
view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
}
}
And here is an example of MyCustomClass
that implements the protocol (with the .xib file being named MyCustomClass.xib
):
@IBDesignable
class MyCustomClass: UIView, NibLoadable {
@IBOutlet weak var myLabel: UILabel!
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setupFromNib()
}
override init(frame: CGRect) {
super.init(frame: frame)
setupFromNib()
}
}
NOTE: If you miss the Gotcha and set the class
value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS
error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder)
method which then calls Self.nib.instantiate
and calls the init
again.

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:
interface TestObject {
name:string;
value:number;
}
@Component({
selector: 'app',
template: `
<h4>Select Object via 2-way binding</h4>
<select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
<option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
</select>
<h4>You selected:</h4> {{selectedObject }}
`,
directives: [FORM_DIRECTIVES]
})
export class App {
objArray:TestObject[];
selectedObject:TestObject;
constructor(){
this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
this.selectedObject = this.objArray[1];
}
updateSelectedValue(event:string): void{
this.selectedObject = JSON.parse(event);
}
}
you can use the '{}' to access you property, and then you can do as you wish. Save it or display the content.
$varName = $xml->{'key'};
From your example her's the code
$filePath = __DIR__ . 'Your path ';
$fileName = 'YourFilename.xml';
if (file_exists($filePath . $fileName)) {
$xml = simplexml_load_file($filePath . $fileName);
$mainNode = $xml->{'code'};
$cityArray = array();
foreach ($mainNode as $key => $data) {
$cityArray[..] = $mainNode[$key]['cityCode'];
....
}
}
Possible Suggestions to make it work:
Some modifications (U forgot to include a semicolon in the statement this.getName=function(){...}
it should be this.getName=function(){...};
)
function Customer(){
this.name="Jhon";
this.getName=function(){
return this.name;
};
}
(This might be one of the problem.)
and
Make sure U Link the JS files in the correct order
<script src="file1.js" type="text/javascript"></script>
<script src="file2.js" type="text/javascript"></script>
If you want to include the column that is the current identity, you can still do that but you have to explicitly list the columns and cast the current identity to an int (assuming it is one now), like so:
select cast (CurrentID as int) as CurrentID, SomeOtherField, identity(int) as TempID
into #temp
from myserver.dbo.mytable
Did you check NULLIF? http://msdn.microsoft.com/en-us/library/ms177562.aspx
This worked for me. But it didn't list in alphabetical order.
find "$(pwd)" -maxdepth 1
This command lists alphabetically as well as lists hidden files too.
ls -d -1 "$PWD/".*; ls -d -1 "$PWD/"*;
dict(zip([1,2,3,4], ['a', 'b', 'c', 'd']))
You Can try this script
<!DOCTYPE html>
<html>
<script>
function getMultipleSelectedValue()
{
var x=document.getElementById("alpha");
for (var i = 0; i < x.options.length; i++) {
if(x.options[i].selected ==true){
alert(x.options[i].value);
}
}
}
</script>
</head>
<body>
<select multiple="multiple" id="alpha">
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
<option value="d">D</option>
</select>
<input type="button" value="Submit" onclick="getMultipleSelectedValue()"/>
</body>

Go to this JVM online test and run it.
Then check the architecture displayed: x86_64 means you have the 64bit version installed, otherwise it's 32bit.
I used the properties plugin to solve this.
Properties are defined in the pom, and written out to a my.properties file, where they can then be accessed from your Java code.
In my case it is test code that needs to access this properties file, so in the pom the properties file is written to maven's testOutputDirectory:
<configuration>
<outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
</configuration>
Use outputDirectory if you want properties to be accessible by your app code:
<configuration>
<outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>
For those looking for a fuller example (it took me a bit of fiddling to get this working as I didn't understand how naming of properties tags affects ability to retrieve them elsewhere in the pom file), my pom looks as follows:
<dependencies>
<dependency>
...
</dependency>
</dependencies>
<properties>
<app.env>${app.env}</app.env>
<app.port>${app.port}</app.port>
<app.domain>${app.domain}</app.domain>
</properties>

</executions>
</plugin>
</plugins>
</build>
And on the command line:
mvn clean test -Dapp.env=LOCAL -Dapp.domain=localhost -Dapp.port=9901
So these properties can be accessed from the Java code:
java.io.InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("my.properties");
java.util.Properties properties = new Properties();
properties.load(inputStream);
appPort = properties.getProperty("app.port");
appDomain = properties.getProperty("app.domain");

T(n/2) = 2T(n/4) + c => T(n) = 4T(n/4) + 2c + c
similarly T(n) = 8T(n/8) + 4c+ 2c + c
....
....
last step ... T(n) = nT(1) + c(sum of powers of 2 from 0 to h(height of tree))
so Complexity is O(2^(h+1) -1)
but h = log(n)
so, O(2n - 1) = O(n)
Here's a performance test for the solutions posted here. https://github.com/tedgonzalez/MaxElementInCollectionPerformance
This is the fastest for Swift 5
array.max()
Pim's answer is very helpful. In my case, I have to use
Expires / Max-Age: "Session"
If it is a dateTime, even it is not expired, it still won't send the cookie to the backend:
Expires / Max-Age: "Thu, 21 May 2020 09:00:34 GMT"
Hope it is helpful for future people who may meet same issue.
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.
One thing which is invariably true is that at this time, the device would be suffocating for some memory (which is usually the reason for GC to most likely get triggered).
As mentioned by almost all authors earlier, this issue surfaces when Android tries to run GC while the app is in background. In most of the cases where we observed it, user paused the app by locking their screen. This might also indicate memory leak somewhere in the application, or the device being too loaded already. So the only legitimate way to minimize it is:
Run below command into the current branch folder to merge from this <commit-id>
to current branch, --no-commit
do not make a new commit automatically
git merge --no-commit <commit-id>
git merge --continue
can only be run after the merge has resulted in conflicts.
git merge --abort
Abort the current conflict resolution process, and try to reconstruct the pre-merge state.
You need to specify an access modifier for your variable. In this case you want it public.
public class Variables
{
public static string name = "";
}
After this you can use the variable like this.
Variables.name
If you just want the bitmap, This too works
InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();
sample uri : content://media/external/images/media/12345
You need to do the following:
public class CountryInfoResponse {
@JsonProperty("geonames")
private List<Country> countries;
//getter - setter
}
RestTemplate restTemplate = new RestTemplate();
List<Country> countries = restTemplate.getForObject("http://api.geonames.org/countryInfoJSON?username=volodiaL",CountryInfoResponse.class).getCountries();
It would be great if you could use some kind of annotation to allow you to skip levels, but it's not yet possible (see this and this)
