The problem with editing JavaScript like you can CSS and HTML is that there is no clean way to propagate the changes. JavaScript can modify the DOM, send Ajax requests, and dynamically modify existing objects and functions at runtime. So, once you have loaded a page with JavaScript, it might be completely different after the JavaScript has run. The browser would have to keep track of every modification your JavaScript code performs so that when you edit the JS, it rolls back the changes to a clean page.
But, you can modify JavaScript dynamically a few other ways:
javascript: alert (1);
The first two options are great because you can modify any JavaScript variables and functions currently in scope. However, you won't be able to modify the code and run it with a "just-served" page like you can with the third option.
Other than that, as far as I know, there is no edit-and-run JavaScript editor in the browser. Hope this helps,
Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.
I don't see a way to run a single untagged test within a test class but I am providing my workflow since it seems to be useful for anyone who runs into this question.
From within a sbt session:
test:testOnly *YourTestClass
(The asterisk is a wildcard, you could specify the full path com.example.specs.YourTestClass
.)
All tests within that test class will be executed. Presumably you're most concerned with failing tests, so correct any failing implementations and then run:
test:testQuick
... which will only execute tests that failed. (Repeating the most recently executed test:testOnly
command will be the same as test:testQuick
in this case, but if you break up your test methods into appropriate test classes you can use a wildcard to make test:testQuick
a more efficient way to re-run failing tests.)
Note that the nomenclature for test in ScalaTest is a test class, not a specific test method, so all untagged methods are executed.
If you have too many test methods in a test class break them up into separate classes or tag them appropriately. (This could be a signal that the class under test is in violation of single responsibility principle and could use a refactoring.)
The above answers seem to resolve the issue. If it doesn't, then you may also try to update conda using the following command.
conda update conda
And then try to install numpy using
conda install numpy
You can use the Background Panel class. It does the custom painting as explained above but gives you options to display the image scaled, tiled or normal size. It also explains how you can use a JLabel with an image as the content pane for the frame.
I usually used to make a function:
function getMonth(monthStr){
return new Date(monthStr+'-1-01').getMonth()+1
}
And call it like :
getMonth('Jan');
getMonth('Feb');
getMonth('Dec');
For majority of us OrElse and AndAlso will do the trick except for a few confusing exceptions (less than 1% where we may have to use Or and And).
Try not to get carried away by people showing off their boolean logics and making it look like a rocket science.
It's quite simple and straight forward and occasionally your system may not work as expected because it doesn't like your logic in the first place. And yet your brain keeps telling you that his logic is 100% tested and proven and it should work. At that very moment stop trusting your brain and ask him to think again or (not OrElse or maybe OrElse) you force yourself to look for another job that doesn't require much logic.
Unfortunately, this is not possible. Per the spec:
Generated content does not alter the document tree. In particular, it is not fed back to the document language processor (e.g., for reparsing).
In other words, for string values this means the value is always treated literally. It is never interpreted as markup, regardless of the document language in use.
As an example, using the given CSS with the following HTML:
<h1 class="header">Title</h1>
... will result in the following output:
You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.
I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.
import cv2
import os
image_folder = 'images'
video_name = 'video.avi'
images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape
video = cv2.VideoWriter(video_name, 0, 1, (width,height))
for image in images:
video.write(cv2.imread(os.path.join(image_folder, image)))
cv2.destroyAllWindows()
video.release()
If you need to do a complex regexp replacement including \r\n, you can workaround the limitation by a three-step approach:
\r\n
by a tag, let's say #GO#
? Check 'Extended', replace \r\n
by #GO#
ICON="*"
from an html bookmarks ? Check regexp, replace ICON=.[^"]+.> by >
#GO#
by \r\n
The Java finalize()
method is not a destructor and should not be used to handle logic that your application depends on. The Java spec states there is no guarantee that the finalize
method is called at all during the livetime of the application.
What you problably want is a combination of finally
and a cleanup method, as in:
MyClass myObj;
try {
myObj = new MyClass();
// ...
} finally {
if (null != myObj) {
myObj.cleanup();
}
}
This will correctly handle the situation when the MyClass()
constructor throws an exception.
I too faced same issue and following steps in resolution of this.
Regards Vj
You can catch it like any other exception:
try {
foo();
}
catch (const std::bad_alloc&) {
return -1;
}
Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.
In general you cannot, and should not try, to respond to this error. bad_alloc
indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.
Worse, modern operating systems often over-allocate: on such systems, malloc
and new
can return a valid pointer even if there is not enough free memory left – std::bad_alloc
will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).
The only thing you could do when catching std::bad_alloc
is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).
In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:
It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.1
OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:
lru_cache<widget> widget_cache;
double perform_operation(int widget_id) {
std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
if (not maybe_widget) {
maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
}
return maybe_widget->frobnicate();
}
…
for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
try {
return perform_operation(widget_id);
} catch (std::bad_alloc const&) {
if (widget_cache.empty()) throw; // memory error elsewhere.
widget_cache.remove_oldest();
}
}
// Handle too many failed attempts here.
But even here, using std::set_new_handler
instead of handling std::bad_alloc
provides the same benefit and would be much simpler.
1 If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.
new
in c++?The usual notion is that if new
operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc
.
However, something more happens even before a bad_alloc
exception is thrown:
C++03 Section 3.7.4.1.3: says
An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.
Consider the following code sample:
#include <iostream>
#include <cstdlib>
// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
std::cerr << "Unable to satisfy request for memory\n";
std::abort();
}
int main()
{
//set the new_handler
std::set_new_handler(outOfMemHandler);
//Request huge memory size, that will cause ::operator new to fail
int *pBigDataArray = new int[100000000L];
return 0;
}
In the above example, operator new
(most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler()
will be called, and the program will abort after issuing an error message.
As seen here the default behavior of new
operator when unable to fulfill a memory request, is to call the new-handler
function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort()
, outOfMemHandler()
would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.
new_handler
and set_new_handler
?new_handler
is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler
is a function that takes and returns a new_handler
.
Something like:
typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();
set_new_handler's parameter is a pointer to the function operator new
should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.
Given the behavior of new
a well designed user program should handle out of memory conditions by providing a proper new_handler
which does one of the following:
Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.
Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler
). The next time operator new calls the new-handler function, it will get the one most recently installed.
(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)
Uninstall the new-handler: This is done by passing a null pointer to set_new_handler
. With no new-handler installed, operator new
will throw an exception ((convertible to) std::bad_alloc
) when memory allocation is unsuccessful.
Throw an exception convertible to std::bad_alloc
. Such exceptions are not be caught by operator new
, but will propagate to the site originating the request for memory.
Not return: By calling abort
or exit
.
To improve the solution of Slinky Sloth I had to add this beforere get from clipboard :
Set objPDF = New MSForms.DataObject
Sadly it didn't worked for a pdf of 10 pages.
var shiftDown = false;
this.onkeydown = function(evt){
var evt2 = evt || window.event;
var keyCode = evt2.keyCode || evt2.which;
if(keyCode==16)shiftDown = true;
}
this.onkeyup = function(){
shiftDown = false;
}
Pick an element in the HTML panel of the developer tools and type this in the console:
angular.element($0).scope()
In WebKit and Firefox, $0
is a reference to the selected DOM node in the elements tab, so by doing this you get the selected DOM node scope printed out in the console.
You can also target the scope by element ID, like so:
angular.element(document.getElementById('yourElementId')).scope()
Addons/Extensions
There are some very useful Chrome extensions that you might want to check out:
Batarang. This has been around for a while.
ng-inspector. This is the newest one, and as the name suggests, it allows you to inspect your application's scopes.
Playing with jsFiddle
When working with jsfiddle you can open the fiddle in show mode by adding /show
at the end of the URL. When running like this you have access to the angular
global. You can try it here:
http://jsfiddle.net/jaimem/Yatbt/show
jQuery Lite
If you load jQuery before AngularJS, angular.element
can be passed a jQuery selector. So you could inspect the scope of a controller with
angular.element('[ng-controller=ctrl]').scope()
Of a button
angular.element('button:eq(1)').scope()
... and so on.
You might actually want to use a global function to make it easier:
window.SC = function(selector){
return angular.element(selector).scope();
};
Now you could do this
SC('button:eq(10)')
SC('button:eq(10)').row // -> value of scope.row

Bill Bumgarner aka @bbum, who should know, posted on the CocoaBuilder mailing list in 2005:
Sun entered the picture a bit after the NS prefix had come into play. The NS prefix came about in public APIs during the move from NeXTSTEP 3.0 to NeXTSTEP 4.0 (also known as OpenStep). Prior to 4.0, a handful of symbols used the NX prefix, but most classes provided by the system libraries were not prefixed at all -- List, Hashtable, View, etc...
It seems that everyone agrees that the prefix NX (for NeXT) was used until 1993/1994, and Apple's docs say:
The official OpenStep API, published in September of 1994, was the first to split the API between Foundation and Application Kit and the first to use the “NS” prefix.
Deleting my commit message worked for me.
rm .git/COMMIT_EDITMSG
It then said.

Start with the highest power of ten that fits into an int
on your platform (for 32 bit int
: 1.000.000.000) and perform an integer division by it. The result is the leftmost digit. Subtract this result multipled with the divisor from the original number, then continue the same game with the next lower power of ten and iterate until you reach 1.
set termout off
doesn't work from the command line, so create a file e.g. termout_off.sql

set termout off
and call this from the SQL prompt:
SQL> @termout_off
PHP's built-in empty() function checks to see whether the variable is empty, null, false, or a representation of zero. It doesn't return true just because the value associated with an array entry is false, in this case the array has actual elements in it and that's all that's evaluated.
If you'd like to check whether a particular error condition is set to true in an associative array, you can use the array_keys() function to filter the keys that have their value set to true.
$set_errors = array_keys( $errors, true );
You can then use the empty() function to check whether this array is empty, simultaneously telling you whether there are errors and also which errors have occurred.
This is best it will do the Job done. It will re-size your Map. No need to inspect element anymore to re-size your Map. What it does it will automatically trigger re-size event .
google.maps.event.addListener(map, "idle", function()
{
google.maps.event.trigger(map, 'resize');
});
map_array[Next].setZoom( map.getZoom() - 1 );
map_array[Next].setZoom( map.getZoom() + 1 );
in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:
<item
android:id="@+id/OK_MENU_ITEM"
android:onClick="showMsgDirectMenuXml" />
And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:
private void showMsgDirectMenuXml(MenuItem item) {
Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
toast.show();
}
NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)
You can use this code to get the next month:
$ts = mktime(0, 0, 0, date("n") + 1, 1);
echo date("Y-m-d H:i:s", $ts);
echo date("n", $ts);
Assuming today is 2013-01-31 01:23:45
the above will return:
2013-02-01 00:00:00

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).
Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle
message because you asked for some nonexistent data.
When you perform a cd
operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.
By default structs do not have a ==
operator. You'll have to write your own implementation:
bool MyStruct1::operator==(const MyStruct1 &other) const {
... // Compare the values, and return a bool result.
}
The Java runtime you try to execute your program with is an earlier version than Java 7 which was the target you compile your program for.
For Ubuntu use
apt-get install openjdk-7-jdk
to get Java 7 as default. You may have to uninstall openjdk-6 first.
Try to remove the constructor and destructors, it's working for me....
In Java 8:
String[] strings = Arrays.stream(objects).toArray(String[]::new);
To convert an array of other types:
String[] strings = Arrays.stream(obj).map(Object::toString).
toArray(String[]::new);
From EL 2.2 specification (get the one below "Click here to download the spec for evaluation"):
1.10 Empty Operator -
empty A
The
empty
operator is a prefix operator that can be used to determine if a value is null or empty.To evaluate
empty A
- If
A
isnull
, returntrue
- Otherwise, if
A
is the empty string, then returntrue
- Otherwise, if
A
is an empty array, then returntrue
- Otherwise, if
A
is an emptyMap
, returntrue
- Otherwise, if
A
is an emptyCollection
, returntrue
- Otherwise return
false
So, considering the interfaces, it works on Collection
and Map
only. In your case, I think Collection
is the best option. Or, if it's a Javabean-like object, then Map
. Either way, under the covers, the isEmpty()
method is used for the actual check. On interface methods which you can't or don't want to implement, you could throw UnsupportedOperationException
.
Slight modification on @JRodd version to support objects coming from Json (JObject)
public static dynamic ToDynamic(this object value)
{
IDictionary<string, object> expando = new ExpandoObject();
//Get the type of object
Type t = value.GetType();
//If is Dynamic Expando object
if (t.Equals(typeof(ExpandoObject)))
{
foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(value.GetType()))
expando.Add(property.Name, property.GetValue(value));
}
//If coming from Json object
else if (t.Equals(typeof(JObject)))
{
foreach (JProperty property in (JToken)value)
expando.Add(property.Name, property.Value);
}
else //Try converting a regular object
{
string str = JsonConvert.SerializeObject(value);
ExpandoObject obj = JsonConvert.DeserializeObject<ExpandoObject>(str);
return obj;
}
return expando as ExpandoObject;
}
resource_url = 'http://localhost:8080/service/'
response = json.loads(urllib2.urlopen(resource_url).read())
To convert the Keys to a List of their own:
listNumber = dicNumber.Select(kvp => kvp.Key).ToList();
Or you can shorten it up and not even bother using select:
listNumber = dicNumber.Keys.ToList();
Looks like you're a little bit confused about all that stuff.
operator
is a built-in module providing a set of convenient operators. In two words operator.itemgetter(n)
constructs a callable that assumes an iterable object (e.g. list, tuple, set) as input, and fetches the n-th element out of it.
So, you can't use key=a[x][1]
there, because python has no idea what x
is. Instead, you could use a lambda
function (elem
is just a variable name, no magic there):
a.sort(key=lambda elem: elem[1])
Or just an ordinary function:
def get_second_elem(iterable):
return iterable[1]
a.sort(key=get_second_elem)
So, here's an important note: in python functions are first-class citizens, so you can pass them to other functions as a parameter.
Other questions:
reverse=True
: a.sort(key=..., reverse=True)
itemgetter
with multiple indices: operator.itemgetter(1,2)
, or with lambda: lambda elem: (elem[1], elem[2])
. This way, iterables are constructed on the fly for each item in list, which are than compared against each other in lexicographic(?) order (first elements compared, if equal - second elements compared, etc)a[2,1]
(indices are zero-based). Using operator... It's possible, but not as clean as just indexing.Refer to the documentation for details:
Assuming SQL Server
(based on your previous questions):
ALTER TABLE Merchant_Pending_Functions ALTER COLUMN NumberOfLocations INT NULL
Replace INT
with your actual datatype.
Yes, you could use either the JavaScript setTimeout()
method or setInterval()
method to invoke the code that you would like to run. Here's how you might do it with setTimeout:
function executeQuery() {
$.ajax({
url: 'url/path/here',
success: function(data) {
// do something with the return value here if you like
}
});
setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}
$(document).ready(function() {
// run the first time; all subsequent calls will take care of themselves
setTimeout(executeQuery, 5000);
});
You should write a kind of template into the @RequestMapping
:
http://localhost:8080/userGrid?_search=${search}&nd=${nd}&rows=${rows}&page=${page}&sidx=${sidx}&sord=${sord}
Now define your business method like following:
@RequestMapping("/userGrid?_search=${search}&nd=${nd}&rows=${rows}&page=${page}&sidx=${sidx}&sord=${sord}")
public @ResponseBody GridModel getUsersForGrid(
@RequestParam(value = "search") String search,
@RequestParam(value = "nd") int nd,
@RequestParam(value = "rows") int rows,
@RequestParam(value = "page") int page,
@RequestParam(value = "sidx") int sidx,
@RequestParam(value = "sort") Sort sort) {
...............
}
So, framework will map ${foo}
to appropriate @RequestParam
.
Since sort may be either asc or desc I'd define it as a enum:
public enum Sort {
asc, desc
}
Spring deals with enums very well.
SUDS is easy to use, but is not guaranteed to be re-entrant. If you're keeping the WSDL Client() object around in a threaded app for better performance, there's some risk involved. The solution to this risk, the clone() method, throws the unrecoverable Python 5508 bug, which seems to print but not really throw an exception. Can be confusing, but it works. It is still by far the best Python SOAP client.
here is an example
<a class="facultySelecter" data-faculty="ahs" href="#">Arts and Human Sciences</a></li>
$('.facultySelecter').click(function() {
var unhide = $(this).data("faculty");
});
this would set var unhide as ahs, so use .data("foo") to get the "foo" value of the data-* attribute you're looking to get

float
and double
don't store decimal places. They store binary places: float
is (assuming IEEE 754) 24 significant bits (7.22 decimal digits) and double is 53 significant bits (15.95 significant digits).
Converting from double
to float
will give you the closest possible float
, so rounding won't help you. Goining the other way may give you "noise" digits in the decimal representation.
#include <stdio.h>
int main(void) {
double orig = 12345.67;
float f = (float) orig;
printf("%.17g\n", f); // prints 12345.669921875
return 0;
}
To get a double
approximation to the nice decimal value you intended, you can write something like:
double round_to_decimal(float f) {
char buf[42];
sprintf(buf, "%.7g", f); // round to 7 decimal digits
return atof(buf);
}

public WebRequest Create(Uri uri)
{
var req = System.Net.WebRequest.CreateHttp(uri);
req.CookieContainer = new CookieContainer();
return req;
}
}
}
Now all you have to do is opt in for which domains you want to use this:
WebRequest.RegisterPrefix("http://example.com/", MyWebRequestCreator.MyHttp);
That means ANY webrequest that goes to example.com will now use your custom webrequest creator, including the standard webclient. This approach means you don't have to touch all you code. You just call the register prefix once and be done with it. You can also register for "http" prefix to opt in for everything everywhere.
Small change to the recursion to so you can for example find the child tab control of a tab control.
public static DependencyObject FindInVisualTreeDown(DependencyObject obj, Type type)
{
if (obj != null)
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
{
DependencyObject child = VisualTreeHelper.GetChild(obj, i);
if (child.GetType() == type)
{
return child;
}
DependencyObject childReturn = FindInVisualTreeDown(child, type);
if (childReturn != null)
{
return childReturn;
}
}
}
return null;
}
This is how we do it in our application
def store_location
session[:return_to] = request.fullpath if request.get? and controller_name != "user_sessions" and controller_name != "sessions"
end
def redirect_back_or_default(default)
redirect_to(session[:return_to] || default)
end
This way you only store last GET request in :return_to
session param, so all forms, even when multiple time POSTed would work with :return_to
.
Create a XIB file :
File -> new File ->ios->cocoa touch class -> next
make sure check mark "also create XIB file"
I would like to perform with tableview
so I choosed subclass UITableViewCell
you can choose as your requerment
XIB file desing as your wish (RestaurantTableViewCell.xib)
we need to grab the row height to set table each row hegiht
Now! need to huck them swift file . i am hucked the restaurantPhoto
and restaurantName
you can huck all of you .
Now adding a UITableView
name
The name of the nib file, which need not include the .nib extension.
owner
The object to assign as the nib’s File's Owner object.
options
A dictionary containing the options to use when opening the nib file.
first
if you do not define first then grabing all view .. so you need to grab one view inside that set frist
.
Bundle.main.loadNibNamed("yourUIView", owner: self, options: nil)?.first as! yourUIView
here is table view controller Full code
import UIKit
class RestaurantTableViewController: UIViewController ,UITableViewDataSource,UITableViewDelegate{
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let restaurantTableviewCell = Bundle.main.loadNibNamed("RestaurantTableViewCell", owner: self, options: nil)?.first as! RestaurantTableViewCell
restaurantTableviewCell.restaurantPhoto.image = UIImage(named: "image1")
restaurantTableviewCell.restaurantName.text = "KFC Chicken"
return restaurantTableviewCell
}
// set row height
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 150
}
}
you done :)
Simple Solution: hide an element on a click event anywhere outside of some specific element.
$(document).on('click', function () {
$('.element').hide();
});
//element will not Hide on click some specific control inside document
$('.control-1').on('click', function (e) {
e.stopPropagation();
});
A more modern option for interpreting HTML (text and otherwise) from JavaScript is the HTML support in the DOMParser
API (see here in MDN). This allows you to use the browser's native HTML parser to convert a string to an HTML document. It has been supported in new versions of all major browsers since late 2014.
If we just want to decode some text content, we can put it as the sole content in a document body, parse the document, and pull out the its .body.textContent
.
var encodedStr = 'hello & world';_x000D_
_x000D_
var parser = new DOMParser;_x000D_
var dom = parser.parseFromString(_x000D_
'<!doctype html><body>' + encodedStr,_x000D_
'text/html');_x000D_
var decodedString = dom.body.textContent;_x000D_
_x000D_
console.log(decodedString);
_x000D_
We can see in the draft specification for DOMParser
that JavaScript is not enabled for the parsed document, so we can perform this text conversion without security concerns.
The
parseFromString(str, type)
method must run these steps, depending on type:
"text/html"
Parse str with an
HTML parser
, and return the newly createdDocument
.The scripting flag must be set to "disabled".
NOTE
script
elements get marked unexecutable and the contents ofnoscript
get parsed as markup.
It's beyond the scope of this question, but please note that if you're taking the parsed DOM nodes themselves (not just their text content) and moving them to the live document DOM, it's possible that their scripting would be reenabled, and there could be security concerns. I haven't researched it, so please exercise caution.
I recommend using ECMAScript 6 spread operator, which will Bind trailing parameters to an array. With this solution you don't need to touch the arguments
object and your code will be simplified. The downside of this solution is that it does not work across most browsers, so instead you will have to use a JS compiler such as Babel. Under the hood Babel transforms arguments
into a Array with a for loop.
function sortArgs(...args) {
return args.sort();
}
If you can not use a ECMAScript 6, I recommend looking at some of the other answers such as @Jonathan Fingland
function sortArgs() {
var args = Array.prototype.slice.call(arguments);
return args.sort();
}
If you're simply locking an object, I'd prefer to use synchronized
Example:
Lock.acquire();
doSomethingNifty(); // Throws a NPE!
Lock.release(); // Oh noes, we never release the lock!
You have to explicitly do try{} finally{}
everywhere.
Whereas with synchronized, it's super clear and impossible to get wrong:
synchronized(myObject) {
doSomethingNifty();
}
That said, Lock
s may be more useful for more complicated things where you can't acquire and release in such a clean manner. I would honestly prefer to avoid using bare Lock
s in the first place, and just go with a more sophisticated concurrency control such as a CyclicBarrier
or a LinkedBlockingQueue
, if they meet your needs.
I've never had a reason to use wait()
or notify()
but there may be some good ones.
OK, I landed here because I recently came across the same issue when checking the classic stack implementation. Just a reminder that this is used in the array based implementation of Stack, which is a bit faster than the linked-list one.
Code below, check the push and pop func.
public class FixedCapacityStackOfStrings
{
private String[] s;
private int N=0;
public FixedCapacityStackOfStrings(int capacity)
{ s = new String[capacity];}
public boolean isEmpty()
{ return N == 0;}
public void push(String item)
{ s[N++] = item; }
public String pop()
{
String item = s[--N];
s[N] = null;
return item;
}
}
It won't throw exception, you'll get an empty list.
mvn -Dschemaname=public liquibase:update
Try to run below example in order to feel how the magical variables work.
@echo off
SETLOCAL EnableDelayedExpansion
echo Full path and filename: %~f0
echo Drive: %~d0
echo Path: %~p0
echo Drive and path: %~dp0
echo Filename without extension: %~n0
echo Filename with extension: %~nx0
echo Extension: %~x0
echo date time : %~t0
echo file size: %~z0
ENDLOCAL
The related rules are following.
%~I - expands %I removing any surrounding quotes ("")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string
If that string comes from a csv file, I would use fgetcsv()
(or str_getcsv()
if you have PHP V5.3). That will allow you to parse quoted values correctly. If it is not a csv, explode()
should be the best choice.
Adding this late answer to show a case most people will come across. If you only need to see what is the last item in the list, use the last
key word:
<div *ngFor="let item of devcaseFeedback.reviewItems; let last = last">
<divider *ngIf="!last"></divider>
</div>
This will add the divider component to every item except the last.
Because of the comment below, I will add the rest of the ngFor
exported values that can be aliased to local variables (As are shown in the docs):
An empty array is defined by omitting values, like so:
v=[[],[]]
a=[]
b=[1,2]
a.push(b)
b==a[0]
Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:
@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
val cacheFile = File(context.cacheDir, "splash_video")
try {
val inputStream = context.assets.open("splash_video")
val outputStream = FileOutputStream(cacheFile)
try {
inputStream.copyTo(outputStream)
} finally {
inputStream.close()
outputStream.close()
}
} catch (e: IOException) {
throw IOException("Could not open splash_video", e)
}
return cacheFile
}
Try this for Windows:
npm uninstall -g cordova
Try this for MAC:
sudo npm uninstall -g cordova
You can also add Cordova like this:
If You Want To install the previous version of Cordova through the Node Package Manager (npm):
npm install -g [email protected]
If You Want To install the latest version of Cordova:
npm install -g cordova
Enjoy!
iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.

I tried to update my project to use the sass using this command
ng set defaults.styleExt scss
but got this
get/set have been deprecated in favor of the config command.
So I deleted my project (as I was just getting started and had no code in my project) and created a new one with sass initially set
ng new my-sassy-app --style=scss
But I would appreciate if someone can share a way to update the existing project as that would be nice.
I just came around this question, but the answers did not satisfy me. So i rolled my own:
echo $(seq 254) | xargs -P255 -I% -d" " ping -W 1 -c 1 192.168.0.% | grep -E "[0-1].*?:"
-W 1
"). So it will finish in 1s :)64 bytes from 192.168.0.16: icmp_seq=1 ttl=64 time=0.019 ms 64 bytes from 192.168.0.12: icmp_seq=1 ttl=64 time=1.78 ms 64 bytes from 192.168.0.21: icmp_seq=1 ttl=64 time=2.43 ms 64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=1.97 ms 64 bytes from 192.168.0.11: icmp_seq=1 ttl=64 time=619 ms
Edit: And here is the same as script, for when your xargs do not have the -P flag, as is the case in openwrt (i just found out)
for i in $(seq 255);
do
ping -W 1 -c 1 10.0.0.$i | grep 'from' &

The documentation you linked actually has the answer in the link associated with the "Java class located out of the source root." Configure your source and test roots and it should work.
https://www.jetbrains.com/idea/webhelp/configuring-content-roots.html
Since you stated that these are tests you should probably go with them marked as Test Source Root instead of Source Root.
SKU can also refer to a unique identifier or code that refers to the particular stock keeping unit. These codes are not regulated or standardized. When a company receives items from a vendor, it has a choice of maintaining the vendor's SKU or creating its own.[2] This makes them distinct from Global Trade Item Number (GTIN), which are standard, global, tracking units. Universal Product Code (UPC), International Article Number (EAN), and Australian Product Number (APN) are special cases of GTINs.
Perhaps I've missed the point (that you need the algorithm and not the ready made solution), but it seems that scala does it out of the box (now):
def combis(str:String, k:Int):Array[String] = {
str.combinations(k).toArray
}
Using the method like this:
println(combis("abcd",2).toList)
Will produce:
List(ab, ac, ad, bc, bd, cd)
setTimout
executes outside of angular. You need to use $timeout
service for this to work:
var app = angular.module('test', []);
app.controller('TestCtrl', function ($scope, $timeout) {
$scope.testValue = 0;
$timeout(function() {
console.log($scope.testValue++);
}, 500);
});
The reason is that two-way binding in angular uses dirty checking. This is a good article to read about angular's dirty checking. $scope.$apply()
kicks off a $digest
cycle. This will apply the binding. $timeout
handles the $apply
for you so it is the recommended service to use when using timeouts.
Essentially, binding happens during the $digest
cycle (if the value is seen to be different).
Quite a late, but different answer to the ones already present here:
If instead of $.ajax
you'd like to use shorthand functions $.get
or $.post
, you can pass arrays this way:
Shorthand GET
var array = [1, 2, 3, 4, 5];
$.get('/controller/MyAction', $.param({ data: array }, true), function(data) {});
// Action Method
public void MyAction(List<int> data)
{
// do stuff here
}
Shorthand POST
var array = [1, 2, 3, 4, 5];
$.post('/controller/MyAction', $.param({ data: array }, true), function(data) {});
// Action Method
[HttpPost]
public void MyAction(List<int> data)
{
// do stuff here
}
Notes:
$.param
is for the
traditional
property, which
MUST be true
for this to work. On linux (debian 9) after resetting the mysql(Maria DB) root password, you just have to edit the phpmyadmin db config file located at /etc/phpmyadmin/config-db.php
gedit /etc/phpmyadmin/config-db.php (as root)
You are missing that rsync can also compare files by checksum.
--size-only
means that rsync will skip files that match in size, even if the timestamps differ. This means it will synchronise fewer files than the default behaviour. It will miss any file with changes that don't affect the overall file size. If you have something that changes the dates on files without changing the files, and you don't want rsync to spend lots of time checksumming those files to discover they haven't changed, this is the option to use.
--ignore-times
means that rsync will checksum every file, even if the timestamps and file sizes match. This means it will synchronise more files than the default behaviour. It will include changes to files even where the file size is the same and the modification date/time has been reset to the original value. Checksumming every file means it has to be entirely read from disk, which may be slow. Some build pipelines will reset timestamps to a specific date (like 1970-01-01) to ensure that the final build file is reproducible bit for bit, e.g. when packed into a tar file that saves the timestamps.
This works fine for me:
while True:
answer = input('Do you want to continue?:')
if answer.lower().startswith("y"):
print("ok, carry on then")
elif answer.lower().startswith("n"):
print("sayonara, Robocop")
exit()
edit: use input
in python 3.2 instead of raw_input
There are several steps when using OpenSSL. You must have an SSL certificate made which can contain the certificate with the private key be sure to specify the exact location of the certificate (this example has it in the root). There are a lot of good tutorials out there.
Some includes:
#include <openssl/applink.c>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>
You will need to initialize OpenSSL:
void InitializeSSL()
{
SSL_load_error_strings();
SSL_library_init();
OpenSSL_add_all_algorithms();
}
void DestroySSL()
{
ERR_free_strings();
EVP_cleanup();
}
void ShutdownSSL()
{
SSL_shutdown(cSSL);
SSL_free(cSSL);
}
Now for the bulk of the functionality. You may want to add a while loop on connections.
int sockfd, newsockfd;
SSL_CTX *sslctx;
SSL *cSSL;
InitializeSSL();
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd< 0)
{
//Log and Error
return;
}
struct sockaddr_in saiServerAddress;
bzero((char *) &saiServerAddress, sizeof(saiServerAddress));
saiServerAddress.sin_family = AF_INET;
saiServerAddress.sin_addr.s_addr = serv_addr;
saiServerAddress.sin_port = htons(aPortNumber);
bind(sockfd, (struct sockaddr *) &serv_addr, sizeof(serv_addr));
listen(sockfd,5);
newsockfd = accept(sockfd, (struct sockaddr *) &cli_addr, &clilen);
sslctx = SSL_CTX_new( SSLv23_server_method());
SSL_CTX_set_options(sslctx, SSL_OP_SINGLE_DH_USE);
int use_cert = SSL_CTX_use_certificate_file(sslctx, "/serverCertificate.pem" , SSL_FILETYPE_PEM);
int use_prv = SSL_CTX_use_PrivateKey_file(sslctx, "/serverCertificate.pem", SSL_FILETYPE_PEM);
cSSL = SSL_new(sslctx);
SSL_set_fd(cSSL, newsockfd );
//Here is the SSL Accept portion. Now all reads and writes must use SSL
ssl_err = SSL_accept(cSSL);
if(ssl_err <= 0)
{
//Error occurred, log and close down ssl
ShutdownSSL();
}
You are then able read or write using:
SSL_read(cSSL, (char *)charBuffer, nBytesToRead);
SSL_write(cSSL, "Hi :3\n", 6);
Update
The SSL_CTX_new
should be called with the TLS method that best fits your needs in order to support the newer versions of security, instead of SSLv23_server_method()
. See:
OpenSSL SSL_CTX_new description
TLS_method(), TLS_server_method(), TLS_client_method(). These are the general-purpose version-flexible SSL/TLS methods. The actual protocol version used will be negotiated to the highest version mutually supported by the client and the server. The supported protocols are SSLv3, TLSv1, TLSv1.1, TLSv1.2 and TLSv1.3.
Is it possible to refactor the nested for loop into a private method? That way you could simply 'return' out of the method to exit the loop.
I think you're mixing up two different paradigms here.
As you noted, the highly flexible ExternalProject
module runs its commands at build time, so you can't make direct use of Project A's import file since it's only created once Project A has been installed.
If you want to include
Project A's import file, you'll have to install Project A manually before invoking Project B's CMakeLists.txt - just like any other third-party dependency added this way or via find_file
/ find_library
/ find_package
.
If you want to make use of ExternalProject_Add
, you'll need to add something like the following to your CMakeLists.txt:
ExternalProject_Add(project_a
URL ...project_a.tar.gz
PREFIX ${CMAKE_CURRENT_BINARY_DIR}/project_a
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR>
)
include(${CMAKE_CURRENT_BINARY_DIR}/lib/project_a/project_a-targets.cmake)
ExternalProject_Get_Property(project_a install_dir)
include_directories(${install_dir}/include)
add_dependencies(project_b_exe project_a)
target_link_libraries(project_b_exe ${install_dir}/lib/alib.lib)
Using MongoDB 4.0 and newer
The $toDate
operator will convert the value to a date. If the value cannot be converted to a date, $toDate
errors. If the value is null or missing, $toDate
returns null:
You can use it within an aggregate pipeline as follows:
db.collection.aggregate([
{ "$addFields": {
"created_at": {
"$toDate": "$created_at"
}
} }
])
The above is equivalent to using the $convert
operator as follows:
db.collection.aggregate([
{ "$addFields": {
"created_at": {
"$convert": {
"input": "$created_at",
"to": "date"
}
}
} }
])
Using MongoDB 3.6 and newer
You cab also use the $dateFromString
operator which converts the date/time string to a date object and has options for specifying the date format as well as the timezone:
db.collection.aggregate([
{ "$addFields": {
"created_at": {
"$dateFromString": {
"dateString": "$created_at",
"format": "%m-%d-%Y" /* <-- option available only in version 4.0. and newer */
}
}
} }
])
Using MongoDB versions >= 2.6 and < 3.2
If MongoDB version does not have the native operators that do the conversion, you would need to manually iterate the cursor returned by the find()
method by either using the forEach()
method
or the cursor method next()
to access the documents. Withing the loop, convert the field to an ISODate object and then update the field using the $set
operator, as in the following example where the field is called created_at
and currently holds the date in string format:
var cursor = db.collection.find({"created_at": {"$exists": true, "$type": 2 }});
while (cursor.hasNext()) {
var doc = cursor.next();
db.collection.update(
{"_id" : doc._id},
{"$set" : {"created_at" : new ISODate(doc.created_at)}}
)
};
For improved performance especially when dealing with large collections, take advantage of using the Bulk API for bulk updates as you will be sending the operations to the server in batches of say 1000 which gives you a better performance as you are not sending every request to the server, just once in every 1000 requests.
The following demonstrates this approach, the first example uses the Bulk API available in MongoDB versions >= 2.6 and < 3.2
. It updates all
the documents in the collection by changing the created_at
fields to date fields:
var bulk = db.collection.initializeUnorderedBulkOp(),
counter = 0;
db.collection.find({"created_at": {"$exists": true, "$type": 2 }}).forEach(function (doc) {
var newDate = new ISODate(doc.created_at);
bulk.find({ "_id": doc._id }).updateOne({
"$set": { "created_at": newDate}
});
counter++;
if (counter % 1000 == 0) {
bulk.execute(); // Execute per 1000 operations and re-initialize every 1000 update statements
bulk = db.collection.initializeUnorderedBulkOp();
}
})
// Clean up remaining operations in queue
if (counter % 1000 != 0) { bulk.execute(); }
Using MongoDB 3.2
The next example applies to the new MongoDB version 3.2
which has since deprecated the Bulk API and provided a newer set of apis using bulkWrite()
:
var bulkOps = [],
cursor = db.collection.find({"created_at": {"$exists": true, "$type": 2 }});
cursor.forEach(function (doc) {
var newDate = new ISODate(doc.created_at);
bulkOps.push(
{
"updateOne": {
"filter": { "_id": doc._id } ,
"update": { "$set": { "created_at": newDate } }
}
}
);
if (bulkOps.length === 500) {
db.collection.bulkWrite(bulkOps);
bulkOps = [];
}
});
if (bulkOps.length > 0) db.collection.bulkWrite(bulkOps);
JavaScript function to check if a file exists:
function doesFileExist(urlToFile)
{
var xhr = new XMLHttpRequest();
xhr.open('HEAD', urlToFile, false);
xhr.send();
if (xhr.status == "404") {
console.log("File doesn't exist");
return false;
} else {
console.log("File exists");
return true;
}
}
SetForegroundWindow( /* window to gain focus */ );
SendKeys.SendWait("^{ESC}"); // ^{ESC} is code for ctrl + esc which mimics the windows key.
I figured it out! The steps make it look like it will take more effort than it actually does.
These instructions are for creating a project from scratch. If you have existing Python scripts that you wish to include in this project, you will obviously need to slightly deviate from these instructions.
If you find that these instructions no longer work or are unclear due to changes in Xcode updates, please let me know. I will make the necessary corrections.
Note that if you open the "Utilities" panel, with the "Show the File inspector" tab active, the file type is automatically set to "Default - Python script". Feel free to look through all the file type options it has, to gain an idea as to what all it is capable of doing. The method above can be applied to any interpreted language. As of right now, I have yet to figure out exactly how to get it to work with Java; then again, I haven't done too much research. Surely there is some documentation floating around on the web about all of this.
If you do not have administrative privileges or are not in the Developer group, you can still use Xcode for Python programming (but you still won't be able to develop in languages that require compiling). Instead of using the play button, in the menu bar, click "Product" ? "Perform Action" ? "Run Without Building" or simply use the keyboard shortcut ^?R.
To change the text encoding, line endings, and/or indentation settings, open the "Utilities" panel and click "Show the File inspector" tab active. There, you will find these settings.
For more information about Xcode's build settings, there is no better source than this. I'd be interested in hearing from somebody who got this to work with unsupported compiled languages. This process should work for any other interpreted language. Just be sure to change Step 5 and Step 16 accordingly.
INADDR_ANY is a constant, that contain 0 in value . this will used only when you want connect from all active ports you don't care about ip-add . so if you want connect any particular ip you should mention like as my_sockaddress.sin_addr.s_addr = inet_addr("192.168.78.2")
Don't know why but in my case it doesn't work the way suggested earlier. But it works like this:
Time.now.change(offset: "-3000")
Of course you need to change offset
value to yours.
you can just use
ls > filenames.txt
(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd
to go to that folder first, or you can ls ~/docs > filenames.txt
This is a different approach - that sort of works..
from random import randint
import datetime
date=datetime.date(randint(2005,2025), randint(1,12),randint(1,28))
BETTER APPROACH
startdate=datetime.date(YYYY,MM,DD)
date=startdate+datetime.timedelta(randint(1,365))
You could try a different approach like read the file line by line instead of dealing with all this nl2br / explode stuff.
$fh = fopen("employees.txt", "r"); if ($fh) { while (($line = fgets($fh)) !== false) { $line = trim($line); echo "<option value='".$line."'>".$line."</option>"; } } else { // error opening the file, do something }
Also maybe just doing a trim (remove whitespace from beginning/end of string) is your issue?
And maybe people are just misunderstanding what you mean by "submitting results to a spreadsheet" -- are you doing this with code? or a copy/paste from an HTML page into a spreadsheet? Maybe you can explain that in more detail. The delimiter for which you split the lines of the file shouldn't be displaying in the output anyway unless you have unexpected output for some other reason.
Not quite, although generally you can usually use some workaround on one of the forms
[^abc]
, which is character by character not a
or b
or c
, a(?!b)
, which is a
not followed by b
(?<!a)b
, which is b
not preceeded by a
Using description
as many of these answers suggest is the wrong approach - even if you get it to work, it will break in iOS 13+.
Instead you should ensure you use the actual binary data, not simply a description of it. Andrey Gagan addressed the Objective C solution quite well, but fortunately it's much simpler in swift:
Swift 4.2 works in iOS 13+
// credit to NSHipster (see link above)
// format specifier produces a zero-padded, 2-digit hexadecimal representation
let deviceTokenString = deviceToken.map { String(format: "%02x", $0) }.joined()
Try to use Action class to reach the element
Actions action = new Actions(driver);
action.MoveToElement(driver.findElement(By.xpath("//a[text()='AppConfiguration']")));
action.Perform();
The simplest way to get the substrings array from the given array is to use filter and includes:
myArray.filter(element => element.includes("substring"));
The above one will return an array of substrings.
myArray.find(element => element.includes("substring"));
The above one will return the first result element from the array.
myArray.findIndex(element => element.includes("substring"));
The above one will return the index of the first result element from the array.
This is how you would drop the constraint
ALTER TABLE <schema_name, sysname, dbo>.<table_name, sysname, table_name>
DROP CONSTRAINT <default_constraint_name, sysname, default_constraint_name>
GO
With a script
-- t-sql scriptlet to drop all constraints on a table
DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)
set @database = 'dotnetnuke'
set @table = 'tabs'
DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
select @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME
from INFORMATION_SCHEMA.TABLE_CONSTRAINTS
where constraint_catalog = @database and
table_name = @table
exec sp_executesql @sql

You seem to be unnecessarily setting properties on your ComboBox
. You can remove the DisplayMemberPath
and SelectedValuePath
properties which have different uses. It might be an idea for you to take a look at the Difference between SelectedItem, SelectedValue and SelectedValuePath post here for an explanation of these properties. Try this:
<ComboBox Name="cbxSalesPeriods"
ItemsSource="{Binding SalesPeriods}"
SelectedItem="{Binding SelectedSalesPeriod}"
IsSynchronizedWithCurrentItem="True"/>
Furthermore, it is pointless using your displayPeriod
property, as the WPF Framework would call the ToString
method automatically for objects that it needs to display that don't have a DataTemplate
set up for them explicitly.
UPDATE >>>
As I can't see all of your code, I cannot tell you what you are doing wrong. Instead, all I can do is to provide you with a complete working example of how to achieve what you want. I've removed the pointless displayPeriod
property and also your SalesPeriodVO
property from your class as I know nothing about it... maybe that is the cause of your problem??. Try this:
public class SalesPeriodV
{
private int month, year;
public int Year
{
get { return year; }
set
{
if (year != value)
{
year = value;
NotifyPropertyChanged("Year");
}
}
}
public int Month
{
get { return month; }
set
{
if (month != value)
{
month = value;
NotifyPropertyChanged("Month");
}
}
}
public override string ToString()
{
return String.Format("{0:D2}.{1}", Month, Year);
}
public virtual event PropertyChangedEventHandler PropertyChanged;
protected virtual void NotifyPropertyChanged(params string[] propertyNames)
{
if (PropertyChanged != null)
{
foreach (string propertyName in propertyNames) PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
PropertyChanged(this, new PropertyChangedEventArgs("HasError"));
}
}
}
Then I added two properties into the view model:
private ObservableCollection<SalesPeriodV> salesPeriods = new ObservableCollection<SalesPeriodV>();
public ObservableCollection<SalesPeriodV> SalesPeriods
{
get { return salesPeriods; }
set { salesPeriods = value; NotifyPropertyChanged("SalesPeriods"); }
}
private SalesPeriodV selectedItem = new SalesPeriodV();
public SalesPeriodV SelectedItem
{
get { return selectedItem; }
set { selectedItem = value; NotifyPropertyChanged("SelectedItem"); }
}
Then initialised the collection with your values:
SalesPeriods.Add(new SalesPeriodV() { Month = 3, Year = 2013 } );
SalesPeriods.Add(new SalesPeriodV() { Month = 4, Year = 2013 } );
And then data bound only these two properties to a ComboBox
:
<ComboBox ItemsSource="{Binding SalesPeriods}" SelectedItem="{Binding SelectedItem}" />
That's it... that's all you need for a perfectly working example. You should see that the display of the items comes from the ToString
method without your displayPeriod
property. Hopefully, you can work out your mistakes from this code example.
Here's probably what you are looking for: php-get-url-query-string. You can combine it with other suggested $_SERVER
parameters.
I quote from http://www.php.net/manual/en/language.oop5.visibility.php
Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an
E_STRICT
warning.
Also you might want to log in via browser and get the command with all headers including cookies:
Open the Network tab of Developer Tools, log in, navigate to the needed page, use "Copy as cURL".
There are known issues with IE and Opera not removing session cookies when setting the expire date to the past (which is what the jQuery cookie plugin does)
This works fine in Safari and Mozilla/FireFox.
You could alternatively overwrite the 'yourElement.addEventListener()' method and use the '.apply()' method to execute the listener like normal, but intercepting the function in the process. Like:
<script type="text/javascript">
var args = [];
var orginalAddEvent = yourElement.addEventListener;
yourElement.addEventListener = function() {
//console.log(arguments);
args[args.length] = arguments[0];
args[args.length] = arguments[1];
orginalAddEvent.apply(this, arguments);
};
function removeListeners() {
for(var n=0;n<args.length;n+=2) {
yourElement.removeEventListener(args[n], args[n+1]);
}
}
removeListeners();
</script>
This script must be run on page load or it might not intercept all event listeners.
Make sure to remove the 'removeListeners()' call before using.

One could install Git for Windows and subsequently run ssh-add
:
Step 3: Add your key to the ssh-agent
To configure the ssh-agent program to use your SSH key:
If you have GitHub for Windows installed, you can use it to clone repositories and not deal with SSH keys. It also comes with the Git Bash tool, which is the preferred way of running git commands on Windows.
Ensure ssh-agent is enabled:
If you are using Git Bash, turn on ssh-agent:
# start the ssh-agent in the background ssh-agent -s # Agent pid 59566
If you are using another terminal prompt, such as msysgit, turn on ssh-agent:
# start the ssh-agent in the background eval $(ssh-agent -s) # Agent pid 59566
Add your SSH key to the ssh-agent:
ssh-add ~/.ssh/id_rsa

Using docker-compose, I found the easiest way to do this is to do a docker ps -a
(after starting my containers with docker-compose up
) and get the ID of the container I want to have an interactive shell in (let's call it xyz123).
Then it's a simple matter to execute
docker exec -ti xyz123 /bin/bash
and voila, an interactive shell.
The Interface describes either a contract for a class or a new type. It is a pure Typescript element, so it doesn't affect Javascript.
A model, and namely a class, is an actual JS function which is being used to generate new objects.
I want to load JSON data from a URL and bind to the Interface/Model.
Go for a model, otherwise it will still be JSON in your Javascript.
Create an array to store the objects:
ArrayList<MyObject> list = new ArrayList<MyObject>();
In a single step:
list.add(new MyObject (1, 2, 3)); //Create a new object and adding it to list.
or
MyObject myObject = new MyObject (1, 2, 3); //Create a new object.
list.add(myObject); // Adding it to the list.
Keys must be unique. Don't do that. Redesign as needed.
(if you are trying to insert, then delete, and the insert fails... just do the delete first. Rollback on error in either statement).
A DATE
column does not have a format. You cannot specify a format for it.
You can use DateStyle
to control how PostgreSQL emits dates, but it's global and a bit limited.
Instead, you should use to_char
to format the date when you query it, or format it in the client application. Like:
SELECT to_char("date", 'DD/MM/YYYY') FROM mytable;
e.g.
regress=> SELECT to_char(DATE '2014-04-01', 'DD/MM/YYYY');
to_char
------------
01/04/2014

Amazed no-one mentioned parallelism here.
If you got really a huge array, you can use parallel-for, on sub ranges. In the end compare all sub-ranges. But parallelism comes width some penalty too, so this would not optimize on small arrays. However if you got huge datasets it starts to make sense, and you get a time division reduction nearing the amount of threads performing the test.
You should make the button call the same page and in a PHP section check if the button was pressed:
HTML:
<form action="theSamePage.php" method="post">
<input type="submit" name="someAction" value="GO" />
</form>
PHP:
<?php
if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['someAction']))
{
func();
}
function func()
{
// do stuff
}
?>
Try this:
Update MasterTbl Set
TotalX = Sum(D.X),
TotalY = Sum(D.Y),
TotalZ = Sum(D.Z)
From MasterTbl M Join DetailTbl D
On D.MasterID = M.MasterID
Depending on which database you are using, if that doesn't work, then try this (this is non-standard SQL but legal in SQL Server):
Update M Set
TotalX = Sum(D.X),
TotalY = Sum(D.Y),
TotalZ = Sum(D.Z)
From MasterTbl M Join DetailTbl D
On D.MasterID = M.MasterID
You have to add it to /etc/paths
.
Reference (which works for me) : Here
exec has memory limitation of buffer size of 512k. In this case it is better to use spawn. With spawn one has access to stdout of executed command at run time

//noinspection JSUnresolvedFunction

"End Process" on the Processes-Tab calls TerminateProcess
which is the most ultimate way Windows knows to kill a process.
If it doesn't go away, it's currently locked waiting on some kernel resource (probably a buggy driver) and there is nothing (short of a reboot) you could do to make the process go away.
Have a look at this blog-entry from wayback when: http://blogs.technet.com/markrussinovich/archive/2005/08/17/unkillable-processes.aspx
Unix based systems like Linux also have that problem where processes could survive a kill -9
if they are in what's known as "Uninterruptible sleep" (shown by top and ps as state D
) at which point the processes sleep so well that they can't process incoming signals (which is what kill
does - sending signals).
Normally, Uninterruptible sleep should not last long, but as under Windows, broken drivers or broken userpace programs (vfork
without exec
) can end up sleeping in D
forever.
You will not only have to use an asp.net page but
If using the Entity Framework or LinqToSql (if using partial classes) move the data into a separate project, the report designer cannot see the classes.
Move the reports to another project/dll, VS10 has bugs were asp.net projects cannot see object datasources in web apps. Then stream the reports from the dll into your mvc projects aspx page.
This applies for mvc and webform projects. Using sql reports in the local mode is not a pleasent development experience. Also watch your webserver memory if exporting large reports. The reportviewer/export is very poorly designed.

I needed something like this for a game's control configuration UI, so I compiled a list for the standard US keyboard layout keycodes and mapped them to their respective key names.
Here's a fiddle that contains a map for code -> name and visi versa: http://jsfiddle.net/vWx8V/
If you want to support other key layouts you'll need to modify these maps to accommodate for them separately.
That is unless you were looking for a list of keycode values that included the control characters and other special values that are not (or are rarely) possible to input using a keyboard and may be outside of the scope of the keydown
/keypress
/keyup
events of Javascript. Many of them are control characters or special characters like null
(\0
) and you most likely won't need them.
Notice that the number of keys on a full keyboard is less than many of the keycode values.
Personally I like to validate the form on submit and if there are errors, just return false.
$('form').submit(function() {
var error;
if ( !$('input').val() ) {
error = true
}
if (error) {
alert('there are errors')
return false
}
});
Just use the exception as intended. Accept that the file is in use and try again, repeatedly until your action is completed. This is also the most efficient because you do not waste any cycles checking the state before acting.
Use the function below, for example
TimeoutFileAction(() => { System.IO.File.etc...; return null; } );
Reusable method that times out after 2 seconds
private T TimeoutFileAction<T>(Func<T> func)
{
var started = DateTime.UtcNow;
while ((DateTime.UtcNow - started).TotalMilliseconds < 2000)
{
try
{
return func();
}
catch (System.IO.IOException exception)
{
//ignore, or log somewhere if you want to
}
}
return default(T);
}
use absolute path where the image actually exists (e.g) '/home/artitra/pictures/filename.jpg'
or create static folder inside your project directory like this
| templates
- static/
- images/
- yourimagename.jpg
then do this
app = Flask(__name__, static_url_path='/static')
then you can access your image like this in index.html
src ="/static/images/yourimage.jpg"
in img tag
Basically, no difference. The only consistent trend is that Python seems to be getting slower with every version... :(

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.
As defined in RFC 821, RFC 2821, and RFC 5321:
SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.
In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.
In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.
The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.
Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.
I encountered the same problem when I tried to install curl in my 32 bit win 7 machine. As answered by Buravchik it is indeed dependency of SSL and installing openssl fixed it. Just a point to take care is that while installing openssl you will get a prompt to ask where do you wish to put the dependent DLLS. Make sure to put it in windows system directory as other programs like curl and wget will also be needing it.
Here is a one-liner: str.replace(/[|\\{}()[\]^$+*?.]/g, '\\$&')
I got it from the escape-string-regexp NPM module.
Trying it out:
escapeStringRegExp.matchOperatorsRe = /[|\\{}()[\]^$+*?.]/g;
function escapeStringRegExp(str) {
return str.replace(escapeStringRegExp.matchOperatorsRe, '\\$&');
}
console.log(new RegExp(escapeStringRegExp('example.com')));
// => /example\.com/
Using tagged template literals with flags support:
function str2reg(flags = 'u') {
return (...args) => new RegExp(escapeStringRegExp(evalTemplate(...args))
, flags)
}
function evalTemplate(strings, ...values) {
let i = 0
return strings.reduce((str, string) => `${str}${string}${
i < values.length ? values[i++] : ''}`, '')
}
console.log(str2reg()`example.com`)
// => /example\.com/u
An explicit call to a parent class constructor is required any time the parent class lacks a no-argument constructor. You can either add a no-argument constructor to the parent class or explicitly call the parent class constructor in your child class.
The error message means that you need to invoke volteado
and siprimo
on an instance of the Program
class. E.g.:
...
Program p = new Program();
long av = p.volteado(a); // av is "a" but swapped
if (p.siprimo(a) == false && p.siprimo(av) == false)
...
They cannot be invoked directly from the Main
method because Main
is static while volteado
and siprimo
are not.
The easiest way to fix this is to make the volteado
and siprimo
methods static:
private static bool siprimo(long a)
{
...
}
private static bool volteado(long a)
{
...

neo4j is:
an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables
I haven't had a chance to try it yet - but it looks very promising. Note this is not an SQL database - your object graph is persisted for you - so it might not be appropriate for your existing app.
Try using absolute positioning, rather than relative positioning
this should get you close - you can adjust by tweaking margins or top/left positions
#play_button {
position:absolute;
transition: .5s ease;
top: 50%;
left: 50%;
}
None of these worked for me. I'm on a mac using Microsoft 360. I found this which DID work: This workaround is for Excel 2010 and 2007, it is best for a small number of chart data points.
Click twice on a label to select it. Click in formula bar. Type = Use your mouse to click on a cell that contains the value you want to use. The formula bar changes to perhaps =Sheet1!$D$3
Repeat step 1 to 5 with remaining data labels.
Simple
A simpler approach like the one Ioannis Filippidis do :
import matplotlib.pyplot as plt
import numpy as np
# evenly sampled time at 200ms intervals
tMin=-1 ;tMax=10
t = np.arange(tMin, tMax, 0.1)
# red dashes, blue points default
plt.plot(t, 22*t, 'r--', t, t**2, 'b')
factor=3/4 ;offset=20 # text position in view
textPosition=[(tMax+tMin)*factor,22*(tMax+tMin)*factor]
plt.text(textPosition[0],textPosition[1]+offset,'22 t',color='red',fontsize=20)
textPosition=[(tMax+tMin)*factor,((tMax+tMin)*factor)**2+20]
plt.text(textPosition[0],textPosition[1]+offset, 't^2', bbox=dict(facecolor='blue', alpha=0.5),fontsize=20)
plt.show()
integer excract from any string
$in = 'tel.123-12-33';
preg_match_all('!\d+!', $in, $matches);
$out = (int)implode('', $matches[0]);
//$out ='1231233';
define ('PATH', $_SERVER['DOCUMENT_ROOT'] . dirname($_SERVER['PHP_SELF']));
$dir = new DirectoryIterator(PATH);
echo '<ul>';
foreach ($dir as $fileinfo)
{
if (!$fileinfo->isDot()) {
echo '<li><a href="'.$fileinfo->getFilename().'" target="_blank">'.$fileinfo->getFilename().'</a></li>';
echo '</li>';
}
}
echo '</ul>';
If you'd like to capture all monitors, you can use the following code:
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] screens = ge.getScreenDevices();
Rectangle allScreenBounds = new Rectangle();
for (GraphicsDevice screen : screens) {
Rectangle screenBounds = screen.getDefaultConfiguration().getBounds();
allScreenBounds.width += screenBounds.width;
allScreenBounds.height = Math.max(allScreenBounds.height, screenBounds.height);
}
Robot robot = new Robot();
BufferedImage screenShot = robot.createScreenCapture(allScreenBounds);
Yes it is possible. You need one ON for each join table.
LEFT JOIN ab
ON ab.sht = cd.sht
LEFT JOIN aa
ON aa.sht = cd.sht
Incidentally my personal formatting preference for complex SQL is described in http://bentilly.blogspot.com/2011/02/sql-formatting-style.html. If you're going to be writing a lot of this, it likely will help.
If you have an image inside a UIImageView , e.g. "myImageView", you can do the following:
Convert your image using UIImageJPEGRepresentation() or UIImagePNGRepresentation() like this:
NSData *data = UIImagePNGRepresentation(myImageView.image);
//or
NSData *data = UIImageJPEGRepresentation(myImageView.image, 0.8);
//The float param (0.8 in this example) is the compression quality
//expressed as a value from 0.0 to 1.0, where 1.0 represents
//the least compression (or best quality).
You can also put this code inside a GCD block and execute in another thread, showing an UIActivityIndicatorView during the process ...
//*code to show a loading view here*
dispatch_queue_t myQueue = dispatch_queue_create("com.my.queue", DISPATCH_QUEUE_SERIAL);
dispatch_async(myQueue, ^{
NSData *data = UIImagePNGRepresentation(myImageView.image);
//some code....
dispatch_async( dispatch_get_main_queue(), ^{
//*code to hide the loading view here*
});
});
You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all
from the stringr
package, though gsub
from base R works just as well.
The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.
x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")
(The base R equivalent is gsub("[[:punct:]]", " ", x)
.)
An alternative is to swap out all non-alphanumeric characters.
str_replace_all(x, "[^[:alnum:]]", " ")
Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.
The type of the elements of an std::map
(which is also the type of an expression obtained by dereferencing an iterator of that map) whose key is K
and value is V
is std::pair<const K, V>
- the key is const
to prevent you from interfering with the internal sorting of map values.
std::pair<>
has two members named first
and second
(see here), with quite an intuitive meaning. Thus, given an iterator i
to a certain map, the expression:
i->first
Which is equivalent to:
(*i).first
Refers to the first (const
) element of the pair
object pointed to by the iterator - i.e. it refers to a key in the map. Instead, the expression:
i->second
Which is equivalent to:
(*i).second
Refers to the second element of the pair
- i.e. to the corresponding value in the map.
I added these two lines of code and work fine for me.
Works in Swift 5+
func adjustUITextViewHeight(textView : UITextView)
{
textView.translatesAutoresizingMaskIntoConstraints = true
textView.isScrollEnabled = false
textView.sizeToFit()
}
You can use it
inside of the shell to iterate over the next 20 results. Just type it
if you see "has more" and you will see the next 20 items.
From cppreference, one of the std::unique_ptr
constructors is
explicit unique_ptr( pointer p ) noexcept;
So to create a new std::unique_ptr
is to pass a pointer to its constructor.
unique_ptr<int> uptr (new int(3));
Or it is the same as
int *int_ptr = new int(3);
std::unique_ptr<int> uptr (int_ptr);
The different is you don't have to clean up after using it. If you don't use std::unique_ptr
(smart pointer), you will have to delete it like this
delete int_ptr;
when you no longer need it or it will cause a memory leak.
Secured way without problems is to make Template of your form You can use it in the same project or any other project. and you can add it very easily, such as adding a new form . Here's a way how make Template
1- from File Menu click Export Template
2- Choose Template Type (Choose item template ) and click next
3-Check Form that you want to make a template of it, and click next Twice
4-Rename your template and (put describe , choose icon image ,preview image if you want)
5-click finish
Now you can add new item and choose your template in any project
MySQL prior to version 8.0 doesn't support the WITH clause (CTE in SQL Server parlance; Subquery Factoring in Oracle), so you are left with using:
The request for the feature dates back to 2006.
As mentioned, you provided a poor example - there's no need to perform a subselect if you aren't altering the output of the columns in any way:
SELECT *
FROM ARTICLE t
JOIN USERINFO ui ON ui.user_userid = t.article_ownerid
JOIN CATEGORY c ON c.catid = t.article_categoryid
WHERE t.published_ind = 0
ORDER BY t.article_date DESC
LIMIT 1, 3
Here's a better example:
SELECT t.name,
t.num
FROM TABLE t
JOIN (SELECT c.id
COUNT(*) 'num'
FROM TABLE c
WHERE c.column = 'a'
GROUP BY c.id) ta ON ta.id = t.id
<?php
$string = 'foo';
if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
// one or more of the 'special characters' found in $string
}
In Java8 you can use streams:
public static Carnet findByCodeIsIn(Collection<Carnet> listCarnet, String codeIsIn) {
return listCarnet.stream().filter(carnet -> codeIsIn.equals(carnet.getCodeIsin())).findFirst().orElse(null);
}
Additionally, in case you have many different objects (not only Carnet
) or you want to find it by different properties (not only by cideIsin
), you could build an utility class, to ecapsulate this logic in it:
public final class FindUtils {
public static <T> T findByProperty(Collection<T> col, Predicate<T> filter) {
return col.stream().filter(filter).findFirst().orElse(null);
}
}
public final class CarnetUtils {
public static Carnet findByCodeTitre(Collection<Carnet> listCarnet, String codeTitre) {
return FindUtils.findByProperty(listCarnet, carnet -> codeTitre.equals(carnet.getCodeTitre()));
}
public static Carnet findByNomTitre(Collection<Carnet> listCarnet, String nomTitre) {
return FindUtils.findByProperty(listCarnet, carnet -> nomTitre.equals(carnet.getNomTitre()));
}
public static Carnet findByCodeIsIn(Collection<Carnet> listCarnet, String codeIsin) {
return FindUtils.findByProperty(listCarnet, carnet -> codeIsin.equals(carnet.getCodeIsin()));
}
}
Is Viewstate turned on?
Edit: Perhaps you should reconsider overriding the rendering function
protected override void RenderContents(HtmlTextWriter output)
{
ddlCountries.RenderControl(output);
ddlStates.RenderControl(output);
}
and instead add the dropdownlists to the control and render the control using the default RenderContents.
Edit: See the answer from Dennis which I alluded to in my previous comment:
Controls.Add ( ddlCountries );
Controls.Add ( ddlStates );
Although I take the risk of not being popular I say they are not useful nowadays.
I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.
Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.
Let's take an example:
On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.
Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.
In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.
Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards
You need to get 2 folders back from your css file.
Try:
background-image: url("../../images/image.png");
All you need is to make an ajax request to your pythoncode. You can do this with jquery http://api.jquery.com/jQuery.ajax/, or use just javascript
$.ajax({
type: "POST",
url: "~/pythoncode.py",
data: { param: text}
}).done(function( o ) {
// do something
});
If you want PHP file caching only, you can use eAccelerator directly. Very easy to install and configure, and give great results.
But too bad, they removed the eaccelerator_put and eaccelerator_put from the latest version 0.9.6.
This provides you to retrieve information from your URI strings
$this->uri->segment(n); // n=1 for controller, n=2 for method, etc
Consider this example:
http://example.com/index.php/controller/action/1stsegment/2ndsegment
it will return
$this->uri->segment(1); // controller
$this->uri->segment(2); // action
$this->uri->segment(3); // 1stsegment
$this->uri->segment(4); // 2ndsegment
I got this message after removing two files from the SRC library, and when I brought them back I kept seeing this error message.
My solution was: Restart Eclipse. Since then I haven't seen this message again :-)
The simplest way would be to convert your hexadecimal string to a byte array and use the File.WriteAllBytes
method.
Using the StringToByteArray()
method from this question, you'd do something like this:
string hexString = "0CFE9E69271557822FE715A8B3E564BE";
File.WriteAllBytes("output.dat", StringToByteArray(hexString));
The StringToByteArray
method is included below:
public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
.Where(x => x % 2 == 0)
.Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
.ToArray();
}
As Mystere Man suggested, getting just a view first and then again making an ajax call again to get the json result is unnecessary in this case. that is 2 calls to the server. I think you can directly return an HTML table of Users in the first call.
We will do this in this way. We will have a strongly typed view which will return the markup of list of users to the browser and this data is being supplied by an action method which we will invoke from our browser using an http request.
Have a ViewModel for the User
public class UserViewModel
{
public int UserID { set;get;}
public string FirstName { set;get;}
//add remaining properties as per your requirement
}
and in your controller have a method to get a list of Users
public class UserController : Controller
{
[HttpGet]
public ActionResult List()
{
List<UserViewModel> objList=UserService.GetUsers(); // this method should returns list of Users
return View("users",objList)
}
}
Assuming that UserService.GetUsers() method will return a List of UserViewModel object which represents the list of usres in your datasource (Tables)
and in your users.cshtml ( which is under Views/User folder),
@model List<UserViewModel>
<table>
@foreach(UserViewModel objUser in Model)
{
<tr>
<td>@objUser.UserId.ToString()</td>
<td>@objUser.FirstName</td>
</tr>
}
</table>
All Set now you can access the url like yourdomain/User/List
and it will give you a list of users in an HTML table.
For Symfony3 In your controller try
$request->server->get('DOCUMENT_ROOT').$request->getBasePath()
If you stick with the design using tables the best idea will be to give an empty row with no content and specified height between each rows in the table.
You can use div to avoid this complexity. Just give a margin to each div.
You probably have Test_Branch checked out, and you may not delete it while it is your current branch. Check out a different branch, and then try deleting Test_Branch.
Swift 3
let phoneNumber: String = "tel://3124235234"
UIApplication.shared.openURL(URL(string: phoneNumber)!)
Using Nuget
Manage NuGet packages...
Browse
tab, search for Oracle
and install Oracle.ManagedDataAccess
In code use the following command (Ctrl+. to automatically add the using directive).
Note the different DataSource string which in comparison to Java is different.
// create connection
OracleConnection con = new OracleConnection();
// create connection string using builder
OracleConnectionStringBuilder ocsb = new OracleConnectionStringBuilder();
ocsb.Password = "autumn117";
ocsb.UserID = "john";
ocsb.DataSource = "database.url:port/databasename";
// connect
con.ConnectionString = ocsb.ConnectionString;
con.Open();
Console.WriteLine("Connection established (" + con.ServerVersion + ")");
For lists or dicts, the answer is more clear, according to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#default-parameter-values use None as default parameter.
But also for strings, a (empty) string object is instanciated at runtime for the keyword parameter.
The cleanest way is probably:
def myfunc(self, my_string=None):
self.my_string = my_string or "" # or a if-else-branch, ...
You can hide a JPanel by calling setVisible(false)
. For example:
public static void main(String args[]){
JFrame f = new JFrame();
f.setLayout(new BorderLayout());
final JPanel p = new JPanel();
p.add(new JLabel("A Panel"));
f.add(p, BorderLayout.CENTER);
//create a button which will hide the panel when clicked.
JButton b = new JButton("HIDE");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
p.setVisible(false);
}
});
f.add(b,BorderLayout.SOUTH);
f.pack();
f.setVisible(true);
}
Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want
x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)
WORD.C <- function(WORDS){
require(wordcloud)
L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))
# Takes a dataframe and the text you want to display
FUN <- function(X, text){
windows()
wordcloud(X[, 1], X[, 2], min.freq=1)
mtext(text, 3, padj=-4.5, col="red") #what I'm trying that isn't working
}
# Now creates the sequence 1,...,length(L2)
# Loops over that and then create an anonymous function
# to send in the information you want to use.
lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})
# Since you asked about loops
# you could use i in seq_along(L2)
# instead of 1:length(L2) if you wanted to
#for(i in 1:length(L2)){
# FUN(L2[[i]], names(L2)[i])
#}
}
WORD.C(list.xy)
In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

At the top first set up database connection as follow:
<?php
$mysqli = new mysqli("localhost", "username", "password", "database") or die($this->mysqli->error);
$query= $mysqli->query("SELECT PcID from PC");

Actually, although I blogged (see Luke's answer), I think this is better than my IDisposable wrapper. Typical code:
Service<IOrderService>.Use(orderService=>
{
orderService.PlaceOrder(request);
});
(edit per comments)
Since Use
returns void, the easiest way to handle return values is via a captured variable:
int newOrderId = 0; // need a value for definite assignment
Service<IOrderService>.Use(orderService=>
{
newOrderId = orderService.PlaceOrder(request);
});
Console.WriteLine(newOrderId); // should be updated
Hope I'm not going offtopic on my first post, but I'd like to expand a little on the casting of integer to string as some respondents appear to have it wrong.
Because the expression in this query uses an arithmetic operator (the plus symbol +), MySQL will convert any strings in the expression to numbers.
To demonstrate, the following will produce the result 6:
SELECT ' 05.05 '+'.95';
String concatenation in MySQL requires the CONCAT() function so there is no ambiguity here and MySQL converts the strings to floats and adds them together.
I actually think the reason the initial query wasn't working is most likely because the $points variable was not in fact set to the user's current points. It was either set to zero, or was unset: MySQL will cast an empty string to zero. For illustration, the following will return 0:
SELECT ABS('');
Like I said, I hope I'm not being too off-topic. I agree that Daan and Tomas have the best solutions for this particular problem.
As shown in the latest edit, the password is valid until 1970, which means it's currently invalid. This explains the error message which is the same as if the password was incorrect.
Reset the validity with:
ALTER USER postgres VALID UNTIL 'infinity';
In a recent question, another user had the same problem with user accounts and PG-9.2:
PostgreSQL - Password authentication fail after adding group roles
So apparently there is a way to unintentionally set a bogus password validity to the Unix epoch (1st Jan, 1970, the minimum possible value for the abstime
type). Possibly, there's a bug in PG itself or in some client tool that would create this situation.
EDIT: it turns out to be a pgadmin bug. See https://dba.stackexchange.com/questions/36137/

With .NET 4.5 you can now unzip files using the .NET framework:
using System;
using System.IO;
namespace ConsoleApplication
{
class Program
{
static void Main(string[] args)
{
string startPath = @"c:\example\start";
string zipPath = @"c:\example\result.zip";
string extractPath = @"c:\example\extract";
System.IO.Compression.ZipFile.CreateFromDirectory(startPath, zipPath);
System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, extractPath);
}
}
}
The above code was taken directly from Microsoft's documentation: http://msdn.microsoft.com/en-us/library/ms404280(v=vs.110).aspx
ZipFile
is contained in the assembly System.IO.Compression.FileSystem
. (Thanks nateirvin...see comment below)
You can also use join:
yourstring = ''.join(('L','yourstring','LL'))
Result:
>>> yourstring
'LyourstringLL'

My laravel installation path was not the same as set in the config file session.php
'domain' => env('SESSION_DOMAIN', 'example.com'),
I've copy/pasted the answer from this question here, and changed the names and spelling to fit this question.
Here is code to measure what is being asked:
#include <iostream>
struct string
{
string() {}
string(const string&) {std::cout << "string(const string&)\n";}
string& operator=(const string&) {std::cout << "string& operator=(const string&)\n";return *this;}
#if (__has_feature(cxx_rvalue_references))
string(string&&) {std::cout << "string(string&&)\n";}
string& operator=(string&&) {std::cout << "string& operator=(string&&)\n";return *this;}
#endif
};
#if PROCESS == 1
string
do_something(string inval)
{
// do stuff
return inval;
}
#elif PROCESS == 2
string
do_something(const string& inval)
{
string return_val = inval;
// do stuff
return return_val;
}
#if (__has_feature(cxx_rvalue_references))
string
do_something(string&& inval)
{
// do stuff
return std::move(inval);
}
#endif
#endif
string source() {return string();}
int main()
{
std::cout << "do_something with lvalue:\n\n";
string x;
string t = do_something(x);
#if (__has_feature(cxx_rvalue_references))
std::cout << "\ndo_something with xvalue:\n\n";
string u = do_something(std::move(x));
#endif
std::cout << "\ndo_something with prvalue:\n\n";
string v = do_something(source());
}
For me this outputs:
$ clang++ -std=c++11 -stdlib=libc++ -DPROCESS=1 test.cpp
$ a.out
do_something with lvalue:
string(const string&)
string(string&&)
do_something with xvalue:
string(string&&)
string(string&&)
do_something with prvalue:
string(string&&)
$ clang++ -std=c++11 -stdlib=libc++ -DPROCESS=2 test.cpp
$ a.out
do_something with lvalue:
string(const string&)
do_something with xvalue:
string(string&&)
do_something with prvalue:
string(string&&)
The table below summarizes my results (using clang -std=c++11). The first number is the number of copy constructions and the second number is the number of move constructions:
+----+--------+--------+---------+
| | lvalue | xvalue | prvalue |
+----+--------+--------+---------+
| p1 | 1/1 | 0/2 | 0/1 |
+----+--------+--------+---------+
| p2 | 1/0 | 0/1 | 0/1 |
+----+--------+--------+---------+
The pass-by-value solution requires only one overload but costs an extra move construction when passing lvalues and xvalues. This may or may not be acceptable for any given situation. Both solutions have advantages and disadvantages.
Your code is valid (with one exception). It is required to have code between BEGIN and END.

An easy alternative that works for me is to insert the svg code into a div. This simple example uses javascript to manipulate the div innerHTML.
svg = '<svg height=150>';
svg+= '<rect height=100% fill=green /><circle cx=150 cy=75 r=60 fill=yellow />';
svg+= '<text x=150 y=95 font-size=60 text-anchor=middle fill=red>IIIIIII</text></svg>';
document.all.d1.innerHTML=svg;

<div id='d1' style="float:right;"></div><hr>

Only correct and W3C compatible answer is: <html>
object and rem. transformation doesn't work correctly if you scale down (for example scale(0.5).
Use:
html
{
font-size: 1mm; /* or your favorite unit */
}
and use in your code "rem" unit (including styles for <body>
) instead metric units. "%"s without changes. For all backgrounds set background-size. Define font-size for body, that is inherited by other elements.
if any condition occurs that shall fire zoom other than 1.0 change the font-size for tag (via CSS or JS).
for example:
@media screen and (max-width:320pt)
{
html
{
font-size: 0.5mm;
}
}
This makes equivalent of zoom:0.5 without problems in JS with clientX and positioning during drag-drop events.
Don't use "rem" in media queries.
You really doesn't need zoom, but in some cases it can faster method for existing sites.
Windows Services do not have UIs. You can redirect the output from a console app to your service with the code shown in this question.
Things to be done to free port 80:
Once you start apache, you can sign into skype.
It is indeed possible with the following code
<div href="#" id='a'>
Hover me
</div>
<div id='b'>
Show me
</div>
and css
#a {
display: block;
}
#a:hover + #b {
display:block;
}
#b {
display:none;
}
Now by hovering on element #a shows element #b.

Since January 7th, 2019, it is possible: unlimited free private repositories on GitHub!
... But for up to three collaborators per private repository.
Nat Friedman just announced it by twitter:
Today(!) we’re thrilled to announce unlimited free private repos for all GitHub users, and a new simplified Enterprise offering:
"New year, new GitHub: Announcing unlimited free private repos and unified Enterprise offering"
For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free.
Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly.
Starting today, those scenarios, and many more, are possible on GitHub at no cost.Public repositories are still free (of course—no changes there) and include unlimited collaborators.
I had the exact same error message, and tried the suggested solutions in this thread but without success.
what solved the problem for me is opening the .xlsx file and saving it as .xls (excel 2003) file.
maybe the file was corrupted or in a different format, and saving it again fixed it.
Access-Control-Allow-Origin
is a CORS (Cross-Origin Resource Sharing) header.
When Site A tries to fetch content from Site B, Site B can send an Access-Control-Allow-Origin
response header to tell the browser that the content of this page is accessible to certain origins. (An origin is a domain, plus a scheme and port number.) By default, Site B's pages are not accessible to any other origin; using the Access-Control-Allow-Origin
header opens a door for cross-origin access by specific requesting origins.
For each resource/page that Site B wants to make accessible to Site A, Site B should serve its pages with the response header:
Access-Control-Allow-Origin: http://siteA.com
Modern browsers will not block cross-domain requests outright. If Site A requests a page from Site B, the browser will actually fetch the requested page on the network level and check if the response headers list Site A as a permitted requester domain. If Site B has not indicated that Site A is allowed to access this page, the browser will trigger the XMLHttpRequest
's error
event and deny the response data to the requesting JavaScript code.
What happens on the network level can be slightly more complex than explained above. If the request is a "non-simple" request, the browser first sends a data-less "preflight" OPTIONS request, to verify that the server will accept the request. A request is non-simple when either (or both):
Accept
Accept-Language
Content-Language
Content-Type
(this is only simple when its value is application/x-www-form-urlencoded
, multipart/form-data
, or text/plain
)If the server responds to the OPTIONS preflight with appropriate response headers (Access-Control-Allow-Headers
for non-simple headers, Access-Control-Allow-Methods
for non-simple verbs) that match the non-simple verb and/or non-simple headers, then the browser sends the actual request.
Supposing that Site A wants to send a PUT request for /somePage
, with a non-simple Content-Type
value of application/json
, the browser would first send a preflight request:
OPTIONS /somePage HTTP/1.1
Origin: http://siteA.com
Access-Control-Request-Method: PUT
Access-Control-Request-Headers: Content-Type
Note that Access-Control-Request-Method
and Access-Control-Request-Headers
are added by the browser automatically; you do not need to add them. This OPTIONS preflight gets the successful response headers:
Access-Control-Allow-Origin: http://siteA.com
Access-Control-Allow-Methods: GET, POST, PUT
Access-Control-Allow-Headers: Content-Type
When sending the actual request (after preflight is done), the behavior is identical to how a simple request is handled. In other words, a non-simple request whose preflight is successful is treated the same as a simple request (i.e., the server must still send Access-Control-Allow-Origin
again for the actual response).
The browsers sends the actual request:
PUT /somePage HTTP/1.1
Origin: http://siteA.com
Content-Type: application/json
{ "myRequestContent": "JSON is so great" }
And the server sends back an Access-Control-Allow-Origin
, just as it would for a simple request:
Access-Control-Allow-Origin: http://siteA.com
See Understanding XMLHttpRequest over CORS for a little more information about non-simple requests.
Try to slightly modify your code:
Sub forEachWs()
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
Call resizingColumns(ws)
Next
End Sub
Sub resizingColumns(ws As Worksheet)
With ws
.Range("A:A").ColumnWidth = 20.14
.Range("B:B").ColumnWidth = 9.71
.Range("C:C").ColumnWidth = 35.86
.Range("D:D").ColumnWidth = 30.57
.Range("E:E").ColumnWidth = 23.57
.Range("F:F").ColumnWidth = 21.43
.Range("G:G").ColumnWidth = 18.43
.Range("H:H").ColumnWidth = 23.86
.Range("i:I").ColumnWidth = 27.43
.Range("J:J").ColumnWidth = 36.71
.Range("K:K").ColumnWidth = 30.29
.Range("L:L").ColumnWidth = 31.14
.Range("M:M").ColumnWidth = 31
.Range("N:N").ColumnWidth = 41.14
.Range("O:O").ColumnWidth = 33.86
End With
End Sub
Note, resizingColumns
routine takes parametr - worksheet to which Ranges belongs.
Basically, when you're using Range("O:O")
- code operats with range from ActiveSheet, that's why you should use With ws
statement and then .Range("O:O")
.
And there is no need to use global variables (unless you are using them somewhere else)
From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning
the following
Excessive GC Time and OutOfMemoryError
The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.
The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).
in conjunction with a passage further down
One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,
java -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.
Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.
Of course, other interpretations are possible.
To see a frequency count for column two (for example):
awk -F '\t' '{print $2}' * | sort | uniq -c | sort -nr
fileA.txt
z z a
a b c
w d e
fileB.txt
t r e
z d a
a g c
fileC.txt
z r a
v d c
a m c
Result:
3 d
2 r
1 z
1 m
1 g
1 b
Unfortunately, you have a malformed url query string, so a regex technique is most appropriate. See what I mean.
There is no need for capture groups. Just match id=
then forget those characters with \K
, then isolate the following one or more digital characters.
Code (Demo)
$str = 'producturl.php?id=736375493?=tm';
echo preg_match('~id=\K\d+~', $str, $out) ? $out[0] : 'no match';
Output:
736375493
You need to have a doGet method as:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hola</title>");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("</body>");
out.println("</html>");
}

With jquery you could do to sth. like this, which will simply switch classes.
$('.showhide').click(function() {
$(this).removeClass('myclass');
$(this).addClass('showhidenew');
});
If you want to switch classes back and forth on each click, you can use toggleClass, like so:
$('.showhide').click(function() {
$(this).toggleClass('myclass');
$(this).toggleClass('showhidenew');
});
If the formula already exists in a cell you can fill it down as follows:
On Mac, use CMD instead of CTRL.
An alternative if the formula is in the first cell of a column:
Once connected to Sql Server 2005 Database, From Object Explorer Window, right click on the database which you want to import table into. Select Tasks -> Import Data. This is a simple tool and allows you to 'map' the incoming data into appropriate table. You can save the scripts to run again when needed.
