use Request.Form
to get the Data
Controller:
[HttpPost]
public ActionResult Index(int? id)
{
string jsonData= Request.Form[0]; // The data from the POST
}
I write this to try
View:
<input type="button" value="post" id="btnPost" />
<script type="text/javascript">
$(function () {
var test = {
number: 456,
name: "Ryu"
}
$("#btnPost").click(function () {
$.post('@Url.Action("Index", "Home")', JSON.stringify(test));
});
});
</script>
and write Request.Form[0]
or Request.Params[0]
in controller can get the data.
I don't write <form> tag
in view.
In order to switch between different views, you could directly change the window.location (using the $location service!) in index.html file
<div ng-controller="Cntrl">
<div ng-click="changeView('edit')">
edit
</div>
<div ng-click="changeView('preview')">
preview
</div>
</div>
Controller.js
function Cntrl ($scope,$location) {
$scope.changeView = function(view){
$location.path(view); // path not hash
}
}
and configure the router to switch to different partials based on the location ( as shown here https://github.com/angular/angular-seed/blob/master/app/app.js ). This would have the benefit of history as well as using ng-view.
Alternatively, you use ng-include with different partials and then use a ng-switch as shown in here ( https://github.com/ganarajpr/Angular-UI-Components/blob/master/index.html )
Here is a better and elegant solution for your problem statement.
int mynumbercheck = 1000;
// Your number to be checked
var myswitch = new Dictionary <Func<int,bool>, Action>
{
{ x => x < 10 , () => //Do this!... },
{ x => x < 100 , () => //Do this!... },
{ x => x < 1000 , () => //Do this!... },
{ x => x < 10000 , () => //Do this!... } ,
{ x => x < 100000 , () => //Do this!... },
{ x => x < 1000000 , () => //Do this!... }
};
Now to call our conditional switch
myswitch.First(sw => sw.Key(mynumbercheck)).Value();
Get rid from your <Button>
wrap div using display:block
and float:left
in both <Button>
and <h1>
and specifying their width
with a position:relative
to your Section
. This approach has the advantage of not needing another div
only to position your <Button>
html
<section>
<h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>
<button>button</button>
</section>
? css
section {
position: relative;
width: 50%;
border: 1px solid;
float:left;
}
h1 {
display: block;
width:70%;
float:left;
}
button
{
position:relative;
top:0;
left:0;
float:left;
}
?
i think the easiest way is to use the Adobe PDF reader COM Component
i hope this helps
Also, bear in mind that if you need to export multiple functions at once, like actions you can use
export * from './XThingActions';
It used to be generally recommended best practice1 to use pass by const ref for all types, except for builtin types (char
, int
, double
, etc.), for iterators and for function objects (lambdas, classes deriving from std::*_function
).
This was especially true before the existence of move semantics. The reason is simple: if you passed by value, a copy of the object had to be made and, except for very small objects, this is always more expensive than passing a reference.
With C++11, we have gained move semantics. In a nutshell, move semantics permit that, in some cases, an object can be passed “by value” without copying it. In particular, this is the case when the object that you are passing is an rvalue.
In itself, moving an object is still at least as expensive as passing by reference. However, in many cases a function will internally copy an object anyway — i.e. it will take ownership of the argument.2
In these situations we have the following (simplified) trade-off:
“Pass by value” still causes the object to be copied, unless the object is an rvalue. In the case of an rvalue, the object can be moved instead, so that the second case is suddenly no longer “copy, then move” but “move, then (potentially) move again”.
For large objects that implement proper move constructors (such as vectors, strings …), the second case is then vastly more efficient than the first. Therefore, it is recommended to use pass by value if the function takes ownership of the argument, and if the object type supports efficient moving.
A historical note:
In fact, any modern compiler should be able to figure out when passing by value is expensive, and implicitly convert the call to use a const ref if possible.
In theory. In practice, compilers can’t always change this without breaking the function’s binary interface. In some special cases (when the function is inlined) the copy will actually be elided if the compiler can figure out that the original object won’t be changed through the actions in the function.
But in general the compiler can’t determine this, and the advent of move semantics in C++ has made this optimisation much less relevant.
1 E.g. in Scott Meyers, Effective C++.
2 This is especially often true for object constructors, which may take arguments and store them internally to be part of the constructed object’s state.
Casting int
to char
involves losing data and the compiler will probably warn you.
Extracting a particular byte from an int
sounds more reasonable and can be done like this:
number & 0x000000ff; /* first byte */
(number & 0x0000ff00) >> 8; /* second byte */
(number & 0x00ff0000) >> 16; /* third byte */
(number & 0xff000000) >> 24; /* fourth byte */
Improving Suman.hassan95's answer by adding a link to subcategory as well. Replace the following code:
$sub_cats = get_categories( $args2 );
if($sub_cats) {
foreach($sub_cats as $sub_category) {
echo $sub_category->name ;
}
}
with:
$sub_cats = get_categories( $args2 );
if($sub_cats) {
foreach($sub_cats as $sub_category) {
echo '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
}
}
or if you also wish a counter for each subcategory, replace with this:
$sub_cats = get_categories( $args2 );
if($sub_cats) {
foreach($sub_cats as $sub_category) {
echo '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
echo apply_filters( 'woocommerce_subcategory_count_html', ' <span class="cat-count">' . $sub_category->count . '</span>', $category );
}
}
The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.
I found that creating a new JsonResult
and returning that is unsatisfactory - having to replace all calls to return Json(obj)
with return new MyJsonResult { Data = obj }
is a pain.
So I figured, why not just hijack the JsonResult
using an ActionFilter
:
public class JsonNetFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
if (filterContext.Result is JsonResult == false)
{
return;
}
filterContext.Result = new JsonNetResult(
(JsonResult)filterContext.Result);
}
private class JsonNetResult : JsonResult
{
public JsonNetResult(JsonResult jsonResult)
{
this.ContentEncoding = jsonResult.ContentEncoding;
this.ContentType = jsonResult.ContentType;
this.Data = jsonResult.Data;
this.JsonRequestBehavior = jsonResult.JsonRequestBehavior;
this.MaxJsonLength = jsonResult.MaxJsonLength;
this.RecursionLimit = jsonResult.RecursionLimit;
}
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
var isMethodGet = string.Equals(
context.HttpContext.Request.HttpMethod,
"GET",
StringComparison.OrdinalIgnoreCase);
if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet
&& isMethodGet)
{
throw new InvalidOperationException(
"GET not allowed! Change JsonRequestBehavior to AllowGet.");
}
var response = context.HttpContext.Response;
response.ContentType = string.IsNullOrEmpty(this.ContentType)
? "application/json"
: this.ContentType;
if (this.ContentEncoding != null)
{
response.ContentEncoding = this.ContentEncoding;
}
if (this.Data != null)
{
response.Write(JsonConvert.SerializeObject(this.Data));
}
}
}
}
This can be applied to any method returning a JsonResult
to use JSON.Net instead:
[JsonNetFilter]
public ActionResult GetJson()
{
return Json(new { hello = new Date(2015, 03, 09) }, JsonRequestBehavior.AllowGet)
}
which will respond with
{"hello":"2015-03-09T00:00:00+00:00"}
as desired!
You can, if you don't mind calling the is
comparison at every request, add this to your FilterConfig
:
// ...
filters.Add(new JsonNetFilterAttribute());
and all of your JSON will now be serialized with JSON.Net instead of the built-in JavaScriptSerializer
.
What about simply
if (condition) { code if condition = true };
You can use the instanceof
operator:
if (obj instanceof jQuery){
console.log('object is jQuery');
}
Explanation: the jQuery
function (aka $
) is implemented as a constructor function. Constructor functions are to be called with the new
prefix.
When you call $(foo)
, internally jQuery translates this to new jQuery(foo)
1. JavaScript proceeds to initialize this
inside the constructor function to point to a new instance of jQuery
, setting it's properties to those found on jQuery.prototype
(aka jQuery.fn
). Thus, you get a new
object where instanceof jQuery
is true
.
1It's actually new jQuery.prototype.init(foo)
: the constructor logic has been offloaded to another constructor function called init
, but the concept is the same.
You can create button in a simple way, such as:
Button button = new Button();
button.Click += new EventHandler(button_Click);
protected void button_Click (object sender, EventArgs e)
{
Button button = sender as Button;
// identify which button was clicked and perform necessary actions
}
But event probably will not fire, because the element/elements must be recreated at every postback or you will lose the event handler.
I tried this solution that verify that ViewState is already Generated and recreate elements at every postback,
for example, imagine you create your button on an event click:
protected void Button_Click(object sender, EventArgs e)
{
if (Convert.ToString(ViewState["Generated"]) != "true")
{
CreateDynamicElements();
}
}
on postback, for example on page load, you should do this:
protected void Page_Load(object sender, EventArgs e)
{
if (Convert.ToString(ViewState["Generated"]) == "true") {
CreateDynamicElements();
}
}
In CreateDynamicElements() you can put all the elements you need, such as your button.
This worked very well for me.
public void CreateDynamicElements(){
Button button = new Button();
button.Click += new EventHandler(button_Click);
}
If you are trying to setup a key for using git with ssh, there's always an option to add a configuration for the identity file.
vi ~/.ssh/config
Host example.com
IdentityFile ~/.ssh/example_key
I tried so many solutions on here that didn't work for me, only displaying some of the ports. But the following displayed All of them and their information.
using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE Caption like '%(COM%'"))
{
var portnames = SerialPort.GetPortNames();
var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p["Caption"].ToString());
var portList = portnames.Select(n => n + " - " + ports.FirstOrDefault(s => s.Contains(n))).ToList();
foreach(string s in portList)
{
Console.WriteLine(s);
}
}
}
Use the array_count_values function.
$countValues = array_count_values($myArray);
echo $countValues["Ben"];
I think returning 0 for succ/1 for fail (glenn jackman) and olibre's clear and explanatory answer says it all; just to mention a kind of "combo" approach for cases where results are not binary and you'd prefer to set a variable rather than "echoing out" a result (for instance if your function is ALSO suppose to echo something, this approach will not work). What then? (below is Bourne Shell)
# Syntax _w (wrapReturn)
# arg1 : method to wrap
# arg2 : variable to set
_w(){
eval $1
read $2 <<EOF
$?
EOF
eval $2=\$$2
}
as in (yep, the example is somewhat silly, it's just an.. example)
getDay(){
d=`date '+%d'`
[ $d -gt 255 ] && echo "Oh no a return value is 0-255!" && BAIL=0 # this will of course never happen, it's just to clarify the nature of returns
return $d
}
dayzToSalary(){
daysLeft=0
if [ $1 -lt 26 ]; then
daysLeft=`expr 25 - $1`
else
lastDayInMonth=`date -d "`date +%Y%m01` +1 month -1 day" +%d`
rest=`expr $lastDayInMonth - 25`
daysLeft=`expr 25 + $rest`
fi
echo "Mate, it's another $daysLeft days.."
}
# main
_w getDay DAY # call getDay, save the result in the DAY variable
dayzToSalary $DAY
Using the useEffect hook, we can easily implement delay feature while typing in input field:
import React, { useState, useEffect } from 'react'
function Search() {
const [searchTerm, setSearchTerm] = useState('')
// Without delay
// useEffect(() => {
// console.log(searchTerm)
// }, [searchTerm])
// With delay
useEffect(() => {
const delayDebounceFn = setTimeout(() => {
console.log(searchTerm)
// Send Axios request here
}, 3000)
// Cleanup fn
return () => clearTimeout(delayDebounceFn)
}, [searchTerm])
return (
<input
autoFocus
type='text'
autoComplete='off'
className='live-search-field'
placeholder='Search here...'
onChange={(e) => setSearchTerm(e.target.value)}
/>
)
}
export default Search
Also make sense to provide Boost version: This will modify original strings.
#include <boost/algorithm/string.hpp>
string str1 = "hello world!!!";
string str2 = "HELLO";
boost::algorithm::to_lower(str1)
boost::algorithm::to_lower(str2)
if (str1.find(str2) != std::string::npos)
{
// str1 contains str2
}
or using perfect boost xpression library
#include <boost/xpressive/xpressive.hpp>
using namespace boost::xpressive;
....
std::string long_string( "very LonG string" );
std::string word("long");
smatch what;
sregex re = sregex::compile(word, boost::xpressive::icase);
if( regex_match( long_string, what, re ) )
{
cout << word << " found!" << endl;
}
In this example you should pay attention that your search word don't have any regex special characters.
No, use transparent
instead none
. See working example here in this example if you will change transparent
to none
it will not work
use like .class { background-color:transparent; }
<div style="cursor: pointer;" onclick="theFunction()" onmouseover="this.style.background='red'" onmouseout="this.style.background=''" ><span>shanghai</span><span>male</span></div>
This will change the background color as well
Since C++11 you should take it by value over const& more often than you might think.
If you are taking the std::shared_ptr (rather than the underlying type T), then you are doing so because you want to do something with it.
If you would like to copy it somewhere, it makes more sense to take it by copy, and std::move it internally, rather than taking it by const& and then later copying it. This is because you allow the caller the option to in turn std::move the shared_ptr when calling your function, thus saving yourself a set of increment and decrement operations. Or not. That is, the caller of the function can decide whether or not he needs the std::shared_ptr around after calling the function, and depending on whether or not move or not. This is not achievable if you pass by const&, and thus it is then preferably to take it by value.
Of course, if the caller both needs his shared_ptr around for longer (thus can not std::move it) and you don't want to create a plain copy in the function (say you want a weak pointer, or you only sometimes want to copy it, depending on some condition), then a const& might still be preferable.
For example, you should do
void enqueue(std::shared<T> t) m_internal_queue.enqueue(std::move(t));
over
void enqueue(std::shared<T> const& t) m_internal_queue.enqueue(t);
Because in this case you always create a copy internally
My own 2¢: you can also subclass defaultdict:
class MyDict(defaultdict):
def __missing__(self, key):
value = [None, None]
self[key] = value
return value
This could come in handy for very complex cases.
Run ---> Debug Configuration ---> YourConfiguration ---> Arguments tab
It does work by just taking the argument 'rb' read binary instead of 'r' read
I used GENEGC's script, but I found it quite slow.
It is slow because it scans whole sheet on every edit.
So I wrote way faster and cleaner method for myself and I wanted to share it.
function onEdit(e) {
if (e) {
var ss = e.source.getActiveSheet();
var r = e.source.getActiveRange();
// If you want to be specific
// do not work in first row
// do not work in other sheets except "MySheet"
if (r.getRow() != 1 && ss.getName() == "MySheet") {
// E.g. status column is 2nd (B)
status = ss.getRange(r.getRow(), 2).getValue();
// Specify the range with which You want to highlight
// with some reading of API you can easily modify the range selection properties
// (e.g. to automatically select all columns)
rowRange = ss.getRange(r.getRow(),1,1,19);
// This changes font color
if (status == 'YES') {
rowRange.setFontColor("#999999");
} else if (status == 'N/A') {
rowRange.setFontColor("#999999");
// DEFAULT
} else if (status == '') {
rowRange.setFontColor("#000000");
}
}
}
}
Use modulo
whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use
if (j % 4 == 0)
Great! Now here is styling available for reCaptcha.. I just use inline styling like:
<div class="g-recaptcha" data-sitekey="XXXXXXXXXXXXXXX" style="transform: scale(1.08); margin-left: 14px;"></div>
whatever you wanna to do small customize in inline styling...
Hope it will help you!!

To export db rather it is SQLITE or ROOM:
Firstly, add this permission in AndroidManifest.xml file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Secondly, we drive to code the db functions:
private void exportDB() {
try {
File dbFile = new File(this.getDatabasePath(DATABASE_NAME).getAbsolutePath());
FileInputStream fis = new FileInputStream(dbFile);
String outFileName = DirectoryName + File.separator +
DATABASE_NAME + ".db";
// Open the empty db as the output stream
OutputStream output = new FileOutputStream(outFileName);
// Transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = fis.read(buffer)) > 0) {
output.write(buffer, 0, length);
}
// Close the streams
output.flush();
output.close();
fis.close();
} catch (IOException e) {
Log.e("dbBackup:", e.getMessage());
}
}
Create Folder on Daily basis with name of folder is Current date:
public void createBackup() {
sharedPref = getSharedPreferences("dbBackUp", MODE_PRIVATE);
editor = sharedPref.edit();
String dt = sharedPref.getString("dt", new SimpleDateFormat("dd-MM-yy").format(new Date()));
if (dt != new SimpleDateFormat("dd-MM-yy").format(new Date())) {
editor.putString("dt", new SimpleDateFormat("dd-MM-yy").format(new Date()));
editor.commit();
}
File folder = new File(Environment.getExternalStorageDirectory() + File.separator + "BackupDBs");
boolean success = true;
if (!folder.exists()) {
success = folder.mkdirs();
}
if (success) {
DirectoryName = folder.getPath() + File.separator + sharedPref.getString("dt", "");
folder = new File(DirectoryName);
if (!folder.exists()) {
success = folder.mkdirs();
}
if (success) {
exportDB();
}
} else {
Toast.makeText(this, "Not create folder", Toast.LENGTH_SHORT).show();
}
}
Assign the DATABASE_NAME without .db extension and its data type is string
With option context, this is possible without permanently setting use_inf_as_na
. For example:
with pd.option_context('mode.use_inf_as_na', True):
df = df.dropna(subset=['col1', 'col2'], how='all')
Of course it can be set to treat inf
as NaN
permanently with
pd.set_option('use_inf_as_na', True)
For older versions, replace use_inf_as_na
with use_inf_as_null
.
return reference is usually used in operator overloading in C++ for large Object, because returning a value need copy operation.(in perator overloading, we usually don't use pointer as return value)
But return reference may cause memory allocation problem. Because a reference to the result will be passed out of the function as a reference to the return value, the return value cannot be an automatic variable.
if you want use returning refernce, you may use a buffer of static object. for example
const max_tmp=5;
Obj& get_tmp()
{
static int buf=0;
static Obj Buf[max_tmp];
if(buf==max_tmp) buf=0;
return Buf[buf++];
}
Obj& operator+(const Obj& o1, const Obj& o1)
{
Obj& res=get_tmp();
// +operation
return res;
}
in this way, you could use returning reference safely.
But you could always use pointer instead of reference for returning value in functiong.
I ended up just creating a headerView that contained a button ( i saw Son Nguyen's solution above after the fact, but heres my code.. it looks like a lot but it's pretty simple):
declare a couple bools for you sections
bool customerIsCollapsed = NO;
bool siteIsCollapsed = NO;
...code
now in your tableview delegate methods...
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, _tblSearchResults.frame.size.width, 35)];
UILabel *lblSection = [UILabel new];
[lblSection setFrame:CGRectMake(0, 0, 300, 30)];
[lblSection setFont:[UIFont fontWithName:@"Helvetica-Bold" size:17]];
[lblSection setBackgroundColor:[UIColor clearColor]];
lblSection.alpha = 0.5;
if(section == 0)
{
if(!customerIsCollapsed)
[lblSection setText:@"Customers --touch to show--"];
else
[lblSection setText:@"Customers --touch to hide--"];
}
else
{
if(!siteIsCollapsed)
[lblSection setText:@"Sites --touch to show--"];
else
[lblSection setText:@"Sites --touch to hide--"]; }
UIButton *btnCollapse = [UIButton buttonWithType:UIButtonTypeCustom];
[btnCollapse setFrame:CGRectMake(0, 0, _tblSearchResults.frame.size.width, 35)];
[btnCollapse setBackgroundColor:[UIColor clearColor]];
[btnCollapse addTarget:self action:@selector(touchedSection:) forControlEvents:UIControlEventTouchUpInside];
btnCollapse.tag = section;
[headerView addSubview:lblSection];
[headerView addSubview:btnCollapse];
return headerView;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
if(section == 0)
{
if(customerIsCollapsed)
return 0;
else
return _customerArray.count;
}
else if (section == 1)
{
if(siteIsCollapsed)
return 0;
else
return _siteArray.count;
}
return 0;
}
and finally the function that gets called when you touch one of the section header buttons:
- (IBAction)touchedSection:(id)sender
{
UIButton *btnSection = (UIButton *)sender;
if(btnSection.tag == 0)
{
NSLog(@"Touched Customers header");
if(!customerIsCollapsed)
customerIsCollapsed = YES;
else
customerIsCollapsed = NO;
}
else if(btnSection.tag == 1)
{
NSLog(@"Touched Site header");
if(!siteIsCollapsed)
siteIsCollapsed = YES;
else
siteIsCollapsed = NO;
}
[_tblSearchResults reloadData];
}
This answer is backing up litb in your comments. I have profound suspicions you are just not displaying the result properly.
I had the exact same thing happen to me once. I spent a whole day trying to figure out why I was getting a bad value into a 64-bit int, only to discover that printf was ignoring the second byte. You can't just pass a 64-bit value into printf like its an int.
No answers have worked for me.
All policies were correct but I have the error when installing a package
Failed to initialize the PowerShell host. If your PowerShell execution policy setting is set to AllSigned, open the Package Manager Console to initialize the host first.
The solution : I have uninstalled the nuget package manager plugin and reinstalled it.
If anybody still looking at this question, the currently accepted answer is now outdated:
Since Python 3.7* the dictionaries are order-preserving, that is they now behave exactly as collections.OrderedDict
s used to. Unfortunately, there is still no dedicated method to index into keys()
/ values()
of the dictionary, so getting the first key / value in the dictionary can be done as
first_key = list(colors)[0]
first_val = list(colors.values())[0]
or alternatively (this avoids instantiating the keys view into a list):
def get_first_key(dictionary):
for key in dictionary:
return key
raise IndexError
first_key = get_first_key(colors)
first_val = colors[first_key]
If you need an n
-th key, then similarly
def get_nth_key(dictionary, n=0):
if n < 0:
n += len(dictionary)
for i, key in enumerate(dictionary.keys()):
if i == n:
return key
raise IndexError("dictionary index out of range")
(*CPython 3.6 already included ordered dicts, but this was only an implementation detail. The language specification includes ordered dicts from 3.7 onwards.)
Isolation level defines how the changes made to some data repository by one transaction affect other simultaneous concurrent transactions, and also how and when that changed data becomes available to other transactions. When we define a transaction using the Spring framework we are also able to configure in which isolation level that same transaction will be executed.
@Transactional(isolation=Isolation.READ_COMMITTED)
public void someTransactionalMethod(Object obj) {
}
READ_UNCOMMITTED isolation level states that a transaction may read data that is still uncommitted by other transactions.
READ_COMMITTED isolation level states that a transaction can't read data that is not yet committed by other transactions.
REPEATABLE_READ isolation level states that if a transaction reads one record from the database multiple times the result of all those reading operations must always be the same.
SERIALIZABLE isolation level is the most restrictive of all isolation levels. Transactions are executed with locking at all levels (read, range and write locking) so they appear as if they were executed in a serialized way.
Propagation is the ability to decide how the business methods should be encapsulated in both logical or physical transactions.
Spring REQUIRED behavior means that the same transaction will be used if there is an already opened transaction in the current bean method execution context.
REQUIRES_NEW behavior means that a new physical transaction will always be created by the container.
The NESTED behavior makes nested Spring transactions to use the same physical transaction but sets savepoints between nested invocations so inner transactions may also rollback independently of outer transactions.
The MANDATORY behavior states that an existing opened transaction must already exist. If not an exception will be thrown by the container.
The NEVER behavior states that an existing opened transaction must not already exist. If a transaction exists an exception will be thrown by the container.
The NOT_SUPPORTED behavior will execute outside of the scope of any transaction. If an opened transaction already exists it will be paused.
The SUPPORTS behavior will execute in the scope of a transaction if an opened transaction already exists. If there isn't an already opened transaction the method will execute anyway but in a non-transactional way.
The trim from jQuery is convenient if you are already using that framework.
$.trim(' your string ');
I tend to use jQuery often, so trimming strings with it is natural for me. But it's possible that there is backlash against jQuery out there? :)
There are pretty limited scenarios that I can think of where this would be useful, but let's assume you can't get funds to purchase VS2012 or something to that effect. If that's the case and you have Windows 7+ and VS 2010 you may be able to use the following hack I put together which seems to work (but I haven't fully deployed an application using this method yet).
Backup your project file!!!
Download and install the Windows 8 SDK which includes the .NET 4.5 SDK.
Open your project in VS2010.
Create a text file in your project named Compile_4_5_CSharp.targets
with the following contents. (Or just download it here - Make sure to remove the ".txt" extension from the file name):
<Project DefaultTargets="Build"
xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<!-- Change the target framework to 4.5 if using the ".NET 4.5" configuration -->
<PropertyGroup Condition=" '$(Platform)' == '.NET 4.5' ">
<DefineConstants Condition="'$(DefineConstants)'==''">
TARGETTING_FX_4_5
</DefineConstants>
<DefineConstants Condition="'$(DefineConstants)'!='' and '$(DefineConstants)'!='TARGETTING_FX_4_5'">
$(DefineConstants);TARGETTING_FX_4_5
</DefineConstants>
<PlatformTarget Condition="'$(PlatformTarget)'!=''"/>
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
</PropertyGroup>
<!-- Import the standard C# targets -->
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<!-- Add .NET 4.5 as an available platform -->
<PropertyGroup>
<AvailablePlatforms>$(AvailablePlatforms),.NET 4.5</AvailablePlatforms>
</PropertyGroup>
</Project>
Unload your project (right click -> unload).
Edit the project file (right click -> Edit *.csproj).
Make the following changes in the project file:
a. Replace the default Microsoft.CSharp.targets
with the target file created in step 4
<!-- Old Import Entry -->
<!-- <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> -->
<!-- New Import Entry -->
<Import Project="Compile_4_5_CSharp.targets" />
b. Change the default platform to .NET 4.5
<!-- Old default platform entry -->
<!-- <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform> -->
<!-- New default platform entry -->
<Platform Condition=" '$(Platform)' == '' ">.NET 4.5</Platform>
c. Add AnyCPU
platform to allow targeting other frameworks as specified in the project properties. This should be added just before the first <ItemGroup>
tag in the file
<PropertyGroup Condition="'$(Platform)' == 'AnyCPU'">
<PlatformTarget>AnyCPU</PlatformTarget>
</PropertyGroup>
.
.
.
<ItemGroup>
.
.
.
Save your changes and close the *.csproj
file.
Reload your project (right click -> Reload Project).
In the configuration manager (Build -> Configuration Manager) make sure the ".NET 4.5" platform is selected for your project.
Still in the configuration manager, create a new solution platform for ".NET 4.5" (you can base it off "Any CPU") and make sure ".NET 4.5" is selected for the solution.
Build your project and check for errors.
Assuming the build completed you can verify that you are indeed targeting 4.5 by adding a reference to a 4.5 specific class to your source code:
using System;
using System.Text;
namespace testing
{
using net45check = System.Reflection.ReflectionContext;
}
When you compile using the ".NET 4.5" platform the build should succeed. When you compile under the "Any CPU" platform you should get a compiler error:
Error 6: The type or namespace name 'ReflectionContext' does not exist in
the namespace 'System.Reflection' (are you missing an assembly reference?)
Remove this line from the connection string that should do it ;) "AttachDbFilename=|DataDirectory|whateverurdatabasenameis-xxxxxxxxxx.mdf"
This post contains 2 examples. I like the 2nd one:
Sub unique()
Dim arr As New Collection, a
Dim aFirstArray() As Variant
Dim i As Long
aFirstArray() = Array("Banana", "Apple", "Orange", "Tomato", "Apple", _
"Lemon", "Lime", "Lime", "Apple")
On Error Resume Next
For Each a In aFirstArray
arr.Add a, a
Next
On Error Goto 0 ' added to original example by PEH
For i = 1 To arr.Count
Cells(i, 1) = arr(i)
Next
End Sub
Scikit learn recently introduced the plot_tree
method to make this very easy (new in version 0.21 (May 2019)). Documentation here.
Here's the minimum code you need:
from sklearn import tree
plt.figure(figsize=(40,20)) # customize according to the size of your tree
_ = tree.plot_tree(your_model_name, feature_names = X.columns)
plt.show()
plot_tree
supports some arguments to beautify the tree. For example:
from sklearn import tree
plt.figure(figsize=(40,20))
_ = tree.plot_tree(your_model_name, feature_names = X.columns,
filled=True, fontsize=6, rounded = True)
plt.show()
If you want to save the picture to a file, add the following line before plt.show()
:
plt.savefig('filename.png')
If you want to view the rules in text format, there's an answer here. It's more intuitive to read.
For yarn users:
yarn add package_name@version_number
That error message generally means there are other processes connected to the DB. Try running this to see which are connected:
exec sp_who
That will return you the process and then you should be able to run:
kill [XXX]
Where [xxx] is the spid
of the process you're trying to kill.
Then you can run your above statement.
Good luck.
When testing for directories remember that every directory contains two special files.
One is called '.' and the other '..'
. is the directory's own name while .. is the name of it's parent directory.
To avoid trailing backslash problems just test to see if the directory knows it's own name.
eg:
if not exist %temp%\buffer\. mkdir %temp%\buffer
The rates that were quoted above are what you would expect to pay US developers; however, I do know some people who have been able to get their apps built for as little as $4,000 by using offshore developers.
Here is a blog post from a group that did this: http://www.lolerapps.com/why-outsourcing-iphone-apps-was-a-no-brainer-for-us
Also, Carla White wrote a fantastic eBook about the process she used to outsource her app called "Inside Secrets to an iPhone App". She talks about how she got a great deal because she was willing to work with a team that was still learning iPhone app development.
So, there are alternatives to the higher price developers discussed above.
After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.
* The arguments which may be supplied in the recovery.command file:
* --send_intent=anystring - write the text out to recovery.intent
* --update_package=path - verify install an OTA package file
* --wipe_data - erase user data (and cache), then reboot
* --wipe_cache - wipe cache (but not user data), then reboot
* --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:
adb shell
recovery --wipe_data
Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.
EDIT:
For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command
For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c
for complete this script , the function for draw circle ,
function drawCircle(coordon)
{
var coord = coordon.split(',');
var c = document.getElementById("myCanvas");
var hdc = c.getContext("2d");
hdc.beginPath();
hdc.arc(coord[0], coord[1], coord[2], 0, 2 * Math.PI);
hdc.stroke();
}
Assuming that ids are unique and you'll only have to remove the one element splice
should do the trick:
var data = [
{"id":"88","name":"Lets go testing"},
{"id":"99","name":"Have fun boys and girls"},
{"id":"108","name":"You are awesome!"}
],
id = 88;
console.table(data);
$.each(data, function(i, el){
if (this.id == id){
data.splice(i, 1);
}
});
console.table(data);
Here is a solution with onBlur, it can be very helpful as it also allows you to format the number the way you need it without requiring any black magic or external library.
const toNumber = (value: string | number) => {
if (typeof value === 'number') return value
return parseInt(value.replace(/[^\d]+/g, ''))
}
const formatPrice = (price: string | number) => {
return new Intl.NumberFormat('es-PY').format(toNumber(price))
}
<input
defaultValue={formatPrice(price)}
onBlur={e => {
const numberValue = toNumber(e.target.value)
setPrice(numberValue)
e.target.value = formatPrice(numberValue)
}}
type='tel'
required
/>
defaultValue
Pay attention: In case your value come from a async source (e.g. fetch): Since defaultValue will only set the value on the first render, you need to make sure to render the component only once the data is there.
This is how I installed it on my machine (ubuntu):
php 7:
sudo apt-get install php7.0-zip
php 5:
sudo apt-get install php5-zip
Edit:
Make sure to restart your server afterwards.
sudo /etc/init.d/apache2 restart
or sudo service nginx restart
PS: If you are using centOS, please check above cweiske's answer
But if you are using a Debian derivated OS, this solution should help you installing php zip extension.
The linked comment is incorrect : 'L' to '1' will produce a rising edge.
In addition, if your clock signal transitions from 'H' to '1', rising_edge(clk)
will (correctly) not trigger while (clk'event and clk = '1')
(incorrectly) will.
Granted, that may look like a contrived example, but I have seen clock waveforms do that in real hardware, due to failures elsewhere.
In PostgreSQL 9.4 to create to file CSV with the header in Ubuntu:
COPY (SELECT * FROM tbl) TO '/home/user/Desktop/result_sql.csv' WITH CSV HEADER;
Note: The folder must be writable.
import numpy as np
a=np.array([[21,20,19,18,17],[16,15,14,13,12],[11,10,9,8,7],[6,5,4,3,2]])
y=np.argsort(a[:,2],kind='mergesort')# a[:,2]=[19,14,9,4]
a=a[y]
print(a)
Desired output is [[6,5,4,3,2],[11,10,9,8,7],[16,15,14,13,12],[21,20,19,18,17]]
note that argsort(numArray)
returns the indices of an numArray
as it was supposed to be arranged in a sorted manner.
example
x=np.array([8,1,5])
z=np.argsort(x) #[1,3,0] are the **indices of the predicted sorted array**
print(x[z]) #boolean indexing which sorts the array on basis of indices saved in z
answer would be [1,5,8]
The schema for passing the value in as a string. The regex will validate a string of at least one digit, possibly followed by a period and exactly two digits:
{
"type": "string",
"pattern": "^[0-9]+(\\.[0-9]{2})?$"
}
The schema below is equivalent, except that it also allows empty strings:
{
"type": "string",
"pattern": "^$|^[0-9]+(\\.[0-9]{2})?$"
}
You need to use backtick instead of single quotes:
Single quote - 'Business Name'
- Wrong
Backtick - `Business Name`
- Correct
i got the same problem, i used malloc over n over again in a loop for adding new char *string data. i faced the same problem, but after releasing the allocated memory void free()
problem were sorted
My approach is slightly different. I do not copy properties into new instances, I just change the prototype of existing POJOs (may not work well on older browsers). Each class is responsible for providing a SetPrototypes method to set the prototoypes of any child objects, which in turn provide their own SetPrototypes methods.
(I also use a _Type property to get the class name of unknown objects but that can be ignored here)
class ParentClass
{
public ID?: Guid;
public Child?: ChildClass;
public ListOfChildren?: ChildClass[];
/**
* Set the prototypes of all objects in the graph.
* Used for recursive prototype assignment on a graph via ObjectUtils.SetPrototypeOf.
* @param pojo Plain object received from API/JSON to be given the class prototype.
*/
private static SetPrototypes(pojo: ParentClass): void
{
ObjectUtils.SetPrototypeOf(pojo.Child, ChildClass);
ObjectUtils.SetPrototypeOfAll(pojo.ListOfChildren, ChildClass);
}

public ID?: Guid;
public GrandChild?: GrandChildClass;
/**
* Set the prototypes of all objects in the graph.
* Used for recursive prototype assignment on a graph via ObjectUtils.SetPrototypeOf.
* @param pojo Plain object received from API/JSON to be given the class prototype.
*/
private static SetPrototypes(pojo: ChildClass): void
{
ObjectUtils.SetPrototypeOf(pojo.GrandChild, GrandChildClass);
}
}
Here is ObjectUtils.ts:
/**
* ClassType lets us specify arguments as class variables.
* (where ClassType == window[ClassName])
*/
type ClassType = { new(...args: any[]): any; };
/**
* The name of a class as opposed to the class itself.
* (where ClassType == window[ClassName])
*/
type ClassName = string & {};
abstract class ObjectUtils
{
/**
* Set the prototype of an object to the specified class.
*
* Does nothing if source or type are null.
* Throws an exception if type is not a known class type.
*
* If type has the SetPrototypes method then that is called on the source
* to perform recursive prototype assignment on an object graph.
*
* SetPrototypes is declared private on types because it should only be called
* by this method. It does not (and must not) set the prototype of the object
* itself - only the protoypes of child properties, otherwise it would cause a
* loop. Thus a public method would be misleading and not useful on its own.

I won't address the READ UNCOMMITTED
argument, just your original question.
Yes, you need WITH(NOLOCK)
on each table of the join. No, your queries are not the same.
Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK)
hint on it.
Is there a command that does?

As mentioned array.find()
is not supported in IE.
However you can read about a Polyfill here:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find#Polyfill
This method has been added to the ECMAScript 2015 specification and may not be available in all JavaScript implementations yet. However, you can polyfill Array.prototype.find with the following snippet:
Code:
// https://tc39.github.io/ecma262/#sec-array.prototype.find
if (!Array.prototype.find) {
Object.defineProperty(Array.prototype, 'find', {
value: function(predicate) {
// 1. Let O be ? ToObject(this value).
if (this == null) {
throw new TypeError('"this" is null or not defined');
}
var o = Object(this);
// 2. Let len be ? ToLength(? Get(O, "length")).
var len = o.length >>> 0;
// 3. If IsCallable(predicate) is false, throw a TypeError exception.
if (typeof predicate !== 'function') {
throw new TypeError('predicate must be a function');
}
// 4. If thisArg was supplied, let T be thisArg; else let T be undefined.
var thisArg = arguments[1];
// 5. Let k be 0.
var k = 0;
// 6. Repeat, while k < len
while (k < len) {
// a. Let Pk be ! ToString(k).
// b. Let kValue be ? Get(O, Pk).
// c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
// d. If testResult is true, return kValue.
var kValue = o[k];
if (predicate.call(thisArg, kValue, k, o)) {
return kValue;
}
// e. Increase k by 1.
k++;
}
// 7. Return undefined.
return undefined;
}
});
}

If you have 5 to 10 minutes, I generally recommend people to read this Integration with Apache Camel by Jonathan Anstey. It's a well written piece which gives a brief introduction to and overview of some of Camel's concepts, and it implements a use case with code samples. In it, Jonathan writes:
Apache Camel is an open source Java framework that focuses on making integration easier and more accessible to developers. It does this by providing:
- concrete implementations of all the widely used Enterprise Integration Patterns (EIPs)
- connectivity to a great variety of transports and APIs
- easy to use Domain Specific Languages (DSLs) to wire EIPs and transports together
There is also a free chapter of Camel in Action (Camel in Action, 2nd ed. is here) which introduces Camel in the first chapter. Jonathan is a co-author on that book with me.
Simple way to display pdf files from database and we can download it.

In any event you many want to try using the --add-host option to docker run to add the ip address of the host into the container's /etc/host file. From there it's trivial to connect to the host on any required port:
Adding entries to a container hosts file
You can add other hosts into a container's /etc/hosts file by using one or more --add-host flags. This example adds a static address for a host named docker:
$ docker run --add-host=docker:10.180.0.1 --rm -it debian $$ ping docker PING docker (10.180.0.1): 48 data bytes 56 bytes from 10.180.0.1: icmp_seq=0 ttl=254 time=7.600 ms 56 bytes from 10.180.0.1: icmp_seq=1 ttl=254 time=30.705 ms ^C--- docker ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/stddev = 7.600/19.152/30.705/11.553 ms
Note: Sometimes you need to connect to the Docker host, which means getting the IP address of the host. You can use the following shell commands to simplify this process:
$ alias hostip="ip route show 0.0.0.0/0 | grep -Eo 'via \S+' | awk '{ print $2 }'" $ docker run --add-host=docker:$(hostip) --rm -it debian
Documentation:
https://docs.docker.com/engine/reference/commandline/run/
Discussions on accessing host from container:
Try the following statement:
select distinct A.[Tag],
count(A.[Tag]) as TAG_COUNT,
(SELECT count(*) FROM [TagTbl] AS B WHERE A.[Tag]=B.[Tag] AND B.[ID]>0)
from [TagTbl] AS A GROUP BY A.[Tag]
The first field will be the tag the second will be the whole count the third will be the positive ones count.
As shown below, range
only supports integers:
>>> range(15.0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: range() integer end argument expected, got float.
>>> range(15)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
>>>
However, c/10
is a float because /
always returns a float.
Before you put it in range
, you need to make c/10
an integer. This can be done by putting it in int
:
range(int(c/10))
or by using //
, which returns an integer:
range(c//10)
You can repaint and / or requery:
On the close event of form B:
Forms!FormA.Requery

As martijn-courteaux said, create a custom component it's the better option. In C# exists a component called PictureBox and I tried to create this component for Java, here is the code:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JComponent;
public class JPictureBox extends JComponent {
private Icon icon = null;
private final Dimension dimension = new Dimension(100, 100);
private Image image = null;
private ImageIcon ii = null;
private SizeMode sizeMode = SizeMode.STRETCH;
private int newHeight, newWidth, originalHeight, originalWidth;
public JPictureBox() {
JPictureBox.this.setPreferredSize(dimension);
JPictureBox.this.setOpaque(false);
JPictureBox.this.setSizeMode(SizeMode.STRETCH);
}
@Override
public void paintComponent(Graphics g) {
if (ii != null) {
switch (getSizeMode()) {
case NORMAL:
g.drawImage(image, 0, 0, ii.getIconWidth(), ii.getIconHeight(), null);
break;
case ZOOM:
aspectRatio();
g.drawImage(image, 0, 0, newWidth, newHeight, null);
break;
case STRETCH:
g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
break;
case CENTER:
g.drawImage(image, (int) (this.getWidth() / 2) - (int) (ii.getIconWidth() / 2), (int) (this.getHeight() / 2) - (int) (ii.getIconHeight() / 2), ii.getIconWidth(), ii.getIconHeight(), null);
break;
default:
g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
}
}
}
public Icon getIcon() {
return icon;
}
public void setIcon(Icon icon) {
this.icon = icon;
ii = (ImageIcon) icon;
image = ii.getImage();
originalHeight = ii.getIconHeight();
originalWidth = ii.getIconWidth();
}
public SizeMode getSizeMode() {
return sizeMode;
}
public void setSizeMode(SizeMode sizeMode) {
this.sizeMode = sizeMode;
}
public enum SizeMode {
NORMAL,
STRETCH,
CENTER,
ZOOM
}
private void aspectRatio() {
if (ii != null) {
newHeight = this.getHeight();
newWidth = (originalWidth * newHeight) / originalHeight;
}
}
}
If you want to add an image, choose the JPictureBox, after that go to Properties and find "icon" property and select an image. If you want to change the sizeMode property then choose the JPictureBox, after that go to Properties and find "sizeMode" property, you can choose some values:

split_part()
does what you want in one step:
SELECT split_part(col, ',', 1) AS col1
, split_part(col, ',', 2) AS col2
, split_part(col, ',', 3) AS col3
, split_part(col, ',', 4) AS col4
FROM tbl;
Add as many lines as you have items in col

String name = "Items";
String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +

OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
DataTable data = new DataTable();
sda.Fill(data);

HTML4/XHTML1 requires
<script type="...">...</script>
HTML5 faces the fact that there is only one scripting language on the web, and allows
<script>...</script>
The latter works in any browser that supports scripting (NN2+).
this one System.IO.Path.GetDirectory(Application.ExecutablePath)
changed to System.IO.Path.GetDirectoryName(Application.ExecutablePath)
This forum suggests also:
SELECT CATALOG_NAME AS DataBaseName FROM INFORMATION_SCHEMA.SCHEMATA
mysql -uroot -p -hslavedb.mydomain.com mydb_production -e "select * from users;"
From the usage printout:
-e
,--execute=name
Execute command and quit. (Disables--force

$ sudo port install py27-pip
Then update your PATH to include py27-pip bin directory (you can add this in ~/.bash_profile PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH
pip will be available in new terminal window.
Answer is to escape the dash!
It looks like what you want to do is remove your first merge. You could follow the following procedure:
git checkout master # Let's make sure we are on master branch
git reset --hard master~ # Let's get back to master before the merge
git pull # or git merge remote/master
git merge topic
That would give you what you want.
I have done some investigation and sharing my results here,this may be useful for others.
First, we can check whether MockSetting option is turned ON
public static boolean isMockSettingsON(Context context) {
// returns true if mock location enabled, false if not enabled.
if (Settings.Secure.getString(context.getContentResolver(),
Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
return false;
else
return true;
}
Second, we can check whether are there other apps in the device, which are using android.permission.ACCESS_MOCK_LOCATION
(Location Spoofing Apps)
public static boolean areThereMockPermissionApps(Context context) {
int count = 0;
PackageManager pm = context.getPackageManager();
List<ApplicationInfo> packages =
pm.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo applicationInfo : packages) {
try {
PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName,
PackageManager.GET_PERMISSIONS);
// Get Permissions
String[] requestedPermissions = packageInfo.requestedPermissions;
if (requestedPermissions != null) {
for (int i = 0; i < requestedPermissions.length; i++) {
if (requestedPermissions[i]
.equals("android.permission.ACCESS_MOCK_LOCATION")
&& !applicationInfo.packageName.equals(context.getPackageName())) {
count++;
}
}
}
} catch (NameNotFoundException e) {
Log.e("Got exception " , e.getMessage());
}
}
if (count > 0)
return true;
return false;
}
If both above methods, first and second are true, then there are good chances that location may be spoofed or fake.
Now, spoofing can be avoided by using Location Manager's API.
We can remove the test provider before requesting the location updates from both the providers (Network and GPS)
LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);
try {
Log.d(TAG ,"Removing Test providers")
lm.removeTestProvider(LocationManager.GPS_PROVIDER);
} catch (IllegalArgumentException error) {
Log.d(TAG,"Got exception in removing test provider");
}
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, locationListener);
I have seen that removeTestProvider(~) works very well over Jelly Bean and onwards version. This API appeared to be unreliable till Ice Cream Sandwich.
Flutter Update:
Use Geolocator and check Position
object's isMocked
property.

window.location.hash is a string
, so do this:
var page_number: number = 3;
window.location.hash = String(page_number);
I think this question is still relevant today. Using the C++11 standard you are now able to implement a instanceof
function without using dynamic_cast
like this:
if (dynamic_cast<B*>(aPtr) != nullptr) {
// aPtr is instance of B
} else {
// aPtr is NOT instance of B
}
But you're still reliant on RTTI
support. So here is my solution for this problem depending on some Macros and Metaprogramming Magic. The only drawback imho is that this approach does not work for multiple inheritance.
InstanceOfMacros.h
#include <set>
#include <tuple>
#include <typeindex>
#define _EMPTY_BASE_TYPE_DECL() using BaseTypes = std::tuple<>;
#define _BASE_TYPE_DECL(Class, BaseClass) \
using BaseTypes = decltype(std::tuple_cat(std::tuple<BaseClass>(), Class::BaseTypes()));
#define _INSTANCE_OF_DECL_BODY(Class) \
static const std::set<std::type_index> baseTypeContainer; \
virtual bool instanceOfHelper(const std::type_index &_tidx) { \
if (std::type_index(typeid(ThisType)) == _tidx) return true; \
if (std::tuple_size<BaseTypes>::value == 0) return false; \
return baseTypeContainer.find(_tidx) != baseTypeContainer.end(); \
} \
template <typename... T> \
static std::set<std::type_index> getTypeIndexes(std::tuple<T...>) { \
return std::set<std::type_index>{std::type_index(typeid(T))...}; \
}
#define INSTANCE_OF_SUB_DECL(Class, BaseClass) \
protected: \
using ThisType = Class; \
_BASE_TYPE_DECL(Class, BaseClass) \
_INSTANCE_OF_DECL_BODY(Class)
#define INSTANCE_OF_BASE_DECL(Class) \
protected: \
using ThisType = Class; \
_EMPTY_BASE_TYPE_DECL() \
_INSTANCE_OF_DECL_BODY(Class) \
public: \
template <typename Of> \
typename std::enable_if<std::is_base_of<Class, Of>::value, bool>::type instanceOf() { \
return instanceOfHelper(std::type_index(typeid(Of))); \
}
#define INSTANCE_OF_IMPL(Class) \
const std::set<std::type_index> Class::baseTypeContainer = Class::getTypeIndexes(Class::BaseTypes());
You can then use this stuff (with caution) as follows:
DemoClassHierarchy.hpp*
#include "InstanceOfMacros.h"
struct A {
virtual ~A() {}
INSTANCE_OF_BASE_DECL(A)
};
INSTANCE_OF_IMPL(A)
struct B : public A {
virtual ~B() {}
INSTANCE_OF_SUB_DECL(B, A)
};
INSTANCE_OF_IMPL(B)
struct C : public A {
virtual ~C() {}
INSTANCE_OF_SUB_DECL(C, A)
};
INSTANCE_OF_IMPL(C)
struct D : public C {
virtual ~D() {}
INSTANCE_OF_SUB_DECL(D, C)
};
INSTANCE_OF_IMPL(D)
The following code presents a small demo to verify rudimentary the correct behavior.
InstanceOfDemo.cpp
#include <iostream>
#include <memory>
#include "DemoClassHierarchy.hpp"
int main() {
A *a2aPtr = new A;
A *a2bPtr = new B;

delete a2aPtr;
delete a2bPtr;
delete c2dPtr;
return 0;
}
Output:

The most interesting question which now arises is, if this evil stuff is more efficient than the usage of dynamic_cast
. Therefore I've written a very basic performance measurement app.
InstanceOfPerformance.cpp
#include <chrono>
#include <iostream>
#include <string>
#include "DemoClassHierarchy.hpp"
template <typename Base, typename Derived, typename Duration>
Duration instanceOfMeasurement(unsigned _loopCycles) {
auto start = std::chrono::high_resolution_clock::now();
volatile bool isInstanceOf = false;
for (unsigned i = 0; i < _loopCycles; ++i) {
Base *ptr = new Derived;
isInstanceOf = ptr->template instanceOf<Derived>();
delete ptr;
}
auto end = std::chrono::high_resolution_clock::now();
return std::chrono::duration_cast<Duration>(end - start);
}
template <typename Base, typename Derived, typename Duration>
Duration dynamicCastMeasurement(unsigned _loopCycles) {
auto start = std::chrono::high_resolution_clock::now();
volatile bool isInstanceOf = false;
for (unsigned i = 0; i < _loopCycles; ++i) {
Base *ptr = new Derived;
isInstanceOf = dynamic_cast<Derived *>(ptr) != nullptr;
delete ptr;
}
auto end = std::chrono::high_resolution_clock::now();
return std::chrono::duration_cast<Duration>(end - start);
}
int main() {
unsigned testCycles = 10000000;
std::string unit = " us";
using DType = std::chrono::microseconds;
std::cout << "InstanceOf performance(A->D) : " << instanceOfMeasurement<A, D, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->C) : " << instanceOfMeasurement<A, C, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->B) : " << instanceOfMeasurement<A, B, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->A) : " << instanceOfMeasurement<A, A, DType>(testCycles).count() << unit
<< "\n"
<< std::endl;
std::cout << "DynamicCast performance(A->D) : " << dynamicCastMeasurement<A, D, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->C) : " << dynamicCastMeasurement<A, C, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->B) : " << dynamicCastMeasurement<A, B, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->A) : " << dynamicCastMeasurement<A, A, DType>(testCycles).count() << unit
<< "\n"
<< std::endl;
return 0;
}
The results vary and are essentially based on the degree of compiler optimization. Compiling the performance measurement program using g++ -std=c++11 -O0 -o instanceof-performance InstanceOfPerformance.cpp
the output on my local machine was:
InstanceOf performance(A->D) : 699638 us
InstanceOf performance(A->C) : 642157 us
InstanceOf performance(A->B) : 671399 us
InstanceOf performance(A->A) : 626193 us
DynamicCast performance(A->D) : 754937 us
DynamicCast performance(A->C) : 706766 us
DynamicCast performance(A->B) : 751353 us
DynamicCast performance(A->A) : 676853 us
Mhm, this result was very sobering, because the timings demonstrates that the new approach is not much faster compared to the dynamic_cast
approach. It is even less efficient for the special test case which tests if a pointer of A
is an instance ofA
. BUT the tide turns by tuning our binary using compiler otpimization. The respective compiler command is g++ -std=c++11 -O3 -o instanceof-performance InstanceOfPerformance.cpp
. The result on my local machine was amazing:
InstanceOf performance(A->D) : 3035 us
InstanceOf performance(A->C) : 5030 us
InstanceOf performance(A->B) : 5250 us
InstanceOf performance(A->A) : 3021 us
DynamicCast performance(A->D) : 666903 us
DynamicCast performance(A->C) : 698567 us
DynamicCast performance(A->B) : 727368 us
DynamicCast performance(A->A) : 3098 us
If you are not reliant on multiple inheritance, are no opponent of good old C macros, RTTI and template metaprogramming and are not too lazy to add some small instructions to the classes of your class hierarchy, then this approach can boost your application a little bit with respect to its performance, if you often end up with checking the instance of a pointer. But use it with caution. There is no warranty for the correctness of this approach.
Note: All demos were compiled using clang (Apple LLVM version 9.0.0 (clang-900.0.39.2))
under macOS Sierra on a MacBook Pro Mid 2012.
Edit:
I've also tested the performance on a Linux machine using gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609
. On this platform the perfomance benefit was not so significant as on macOs with clang.
Output (without compiler optimization):
InstanceOf performance(A->D) : 390768 us
InstanceOf performance(A->C) : 333994 us
InstanceOf performance(A->B) : 334596 us
InstanceOf performance(A->A) : 300959 us
DynamicCast performance(A->D) : 331942 us
DynamicCast performance(A->C) : 303715 us
DynamicCast performance(A->B) : 400262 us

...which seems to be the intended and most portable way
the concept of python urllib is to group the numerous attributes of the request into various managers/directors/contexts... which then process their parts:
import urllib.request, ssl
# to avoid verifying ssl certificates
httpsHa = urllib.request.HTTPSHandler(context= ssl._create_unverified_context())
# setting up realm+urls+user-password auth
# (top_level_url may be sequence, also the complete url, realm None is default)
top_level_url = 'https://ip:port_or_domain'
# of the std managers, this can send user+passwd in one go,
# not after HTTP req->401 sequence
password_mgr = urllib.request.HTTPPasswordMgrWithPriorAuth()
password_mgr.add_password(None, top_level_url, "user", "password", is_authenticated=True)
handler = urllib.request.HTTPBasicAuthHandler(password_mgr)
# create OpenerDirector
opener = urllib.request.build_opener(handler, httpsHa)
url = top_level_url + '/some_url?some_query...'
response = opener.open(url)
print(response.read())
If you run VMware Player or Workstation (or maybe VirtualBox, I'm not sure if it supports Mac OS X, but may), and then Mac OS X Server (Client can't legally be virtualized). Of course, in this case you are running XCode on OS X, but your host machine could be linux.
We can use it as a function too. Angular throws some error if used as a prototype. Thanks @HarpyWar. It helped me solve a problem.
var removeItem = function (object, key, value) {
if (value == undefined)
return;
for (var i in object) {
if (object[i][key] == value) {
object.splice(i, 1);
}
}
};
var collection = [

Note: Answer has been updated to cover the scenario where background
is an instance of ColorDrawable
. Thanks Tyler Pfaff, for pointing this out.
The drawable is an oval and is the background of an ImageView
Get the Drawable
from imageView
using getBackground()
:
Drawable background = imageView.getBackground();
Check against usual suspects:
if (background instanceof ShapeDrawable) {
// cast to 'ShapeDrawable'
ShapeDrawable shapeDrawable = (ShapeDrawable) background;
shapeDrawable.getPaint().setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
} else if (background instanceof GradientDrawable) {
// cast to 'GradientDrawable'
GradientDrawable gradientDrawable = (GradientDrawable) background;
gradientDrawable.setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
} else if (background instanceof ColorDrawable) {
// alpha value may need to be set again after this call
ColorDrawable colorDrawable = (ColorDrawable) background;
colorDrawable.setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
}
Compact version:
Drawable background = imageView.getBackground();
if (background instanceof ShapeDrawable) {
((ShapeDrawable)background).getPaint().setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
} else if (background instanceof GradientDrawable) {
((GradientDrawable)background).setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
} else if (background instanceof ColorDrawable) {
((ColorDrawable)background).setColor(ContextCompat.getColor(mContext,R.color.colorToSet));
}
Note that null-checking is not required.
However, you should use mutate()
on the drawables before modifying them if they are used elsewhere. (By default, drawables loaded from XML share the same state.)
The following is what this would look like inside of .draggable({});
$("#yourDraggable").draggable({
revert: "invalid" ,
start: function(){
$(this).css("opacity",0.3);
},
stop: function(){
$(this).draggable( 'disable' )
},
opacity: 0.7,
helper: function () {
$copy = $(this).clone();
$copy.css({
"list-style":"none",
"width":$(this).outerWidth()
});
return $copy;
},
appendTo: 'body',
scroll: false
});
With a simple JSON object, you don't need jQuery:
for (var i in json) {
for (var j in json[i]) {
console.log(json[i][j]);
}
}
This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
We can use Array.sort method to sort this array.
var array = ["ab", "abcdefgh", "abcd"];
array.sort(function(a, b){return b.length - a.length});
console.log(JSON.stringify(array, null, '\t'));
_x000D_
For ascending sort order:
a.length - b.length
For descending sort order:
b.length - a.length
Attention: not all browsers can understand ES6 code!
In ES6 we can use an arrow function expressions.
let array = ["ab", "abcdefgh", "abcd"];
array.sort((a, b) => b.length - a.length);
console.log(JSON.stringify(array, null, '\t'));

My guess is that you simply need to URL-encode your Base64 string when you include it in the querystring.
Base64 encoding uses some characters which must be encoded if they're part of a querystring (namely +
and /
, and maybe =
too). If the string isn't correctly encoded then you won't be able to decode it successfully at the other end, hence the errors.
You can use the HttpUtility.UrlEncode
method to encode your Base64 string:
string msg = "Please click on the link below or paste it into a browser "
+ "to verify your email account.<br /><br /><a href=\""
+ _configuration.RootURL + "Accounts/VerifyEmail.aspx?a="
+ HttpUtility.UrlEncode(userName.Encrypt("verify")) + "\">"
+ _configuration.RootURL + "Accounts/VerifyEmail.aspx?a="
+ HttpUtility.UrlEncode(userName.Encrypt("verify")) + "</a>";

It's very important for accessibility reasons that you always specify value of the submit even if you are hiding this text, or if you use <input type="image" .../>
to always specify alt=""
attribute for this input field.
Blind people don't know what button will do if it doesn't contain meaningful alt=""
or value=""
.
We can add the following to a particular tag in CSS:
-webkit-transform: rotate(90deg);
-moz-transform: rotate(90deg);
-o-transform: rotate(90deg);
-ms-transform: rotate(90deg);
transform: rotate(90deg);
In case of half rotation change 90
to 45
.
See the Create a video slideshow from images – FFmpeg
If your video does not show the frames correctly If you encounter problems, such as the first image is skipped or only shows for one frame, then use the fps video filter instead of -r for the output framerate
ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4
Alternatively the format video filter can be added to the filter chain to replace -pix_fmt yuv420p like "fps=25,format=yuv420p". The advantage of this method is that you can control which filter goes first
ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4
I tested below parameters, it worked for me
"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -vf "fps=25,format=yuv420p" e:\out.mp4
below parameters also worked but it always skips the first image
"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p e:\out.mp4
making a video from images placed in different folders
First, add image paths to imagepaths.txt like below.
# this is a comment details https://trac.ffmpeg.org/wiki/Concatenate
file 'E:\images\png\images__%3d.jpg'
file 'E:\images\jpg\images__%3d.jpg'
Sample usage as follows;
"h:\ffmpeg\ffmpeg.exe" -y -r 1/5 -f concat -safe 0 -i "E:\images\imagepaths.txt" -c:v libx264 -vf "fps=25,format=yuv420p" "e:\out.mp4"
-safe 0 parameter prevents Unsafe file name error

You're correct in that the document.getElementById("demo")
call gets you the element by the specified ID. But you have to look at the rest of the statement to figure out what exactly the code is doing with that element:
.innerHTML=voteable;
You can see here that it's setting the innerHTML
of that element to the value of voteable
.

I know this is a very old post but as I was searching for additional solutions to this same error while running my command (I'd previously encountered the spaces in the Excel wb headers and remedied it with VBA each time the file is updated so I knew it wasn't that). I considered the fact that the xlsm file and DB were on separate network drives but didn't want to explore moving one unless it was my last resort.
I attempted to run the save import manually and there it was right in front of my face. The folder containing the xlsm file had been renamed....I changed the name back to match my saved import and....smh, it was that all along.

The query for MongoDB here fees is collection and description is a field.
db.getCollection('fees').find({},{description:1,_id:0})
Deny
takes precedence over Allow
. Local rules take precedence over inherited rules. I have seen many solutions (including some answers shown here), but none of them takes into account whether rules are inherited or not. Therefore I suggest the following approach that considers rule inheritance (neatly wrapped into a class):
public class CurrentUserSecurity
{
WindowsIdentity _currentUser;
WindowsPrincipal _currentPrincipal;
public CurrentUserSecurity()
{
_currentUser = WindowsIdentity.GetCurrent();
_currentPrincipal = new WindowsPrincipal(_currentUser);
}
public bool HasAccess(DirectoryInfo directory, FileSystemRights right)
{
// Get the collection of authorization rules that apply to the directory.
AuthorizationRuleCollection acl = directory.GetAccessControl()
.GetAccessRules(true, true, typeof(SecurityIdentifier));
return HasFileOrDirectoryAccess(right, acl);
}
public bool HasAccess(FileInfo file, FileSystemRights right)
{
// Get the collection of authorization rules that apply to the file.
AuthorizationRuleCollection acl = file.GetAccessControl()
.GetAccessRules(true, true, typeof(SecurityIdentifier));
return HasFileOrDirectoryAccess(right, acl);
}
private bool HasFileOrDirectoryAccess(FileSystemRights right,
AuthorizationRuleCollection acl)
{
bool allow = false;
bool inheritedAllow = false;
bool inheritedDeny = false;
for (int i = 0; i < acl.Count; i++) {
var currentRule = (FileSystemAccessRule)acl[i];
// If the current rule applies to the current user.
if (_currentUser.User.Equals(currentRule.IdentityReference) ||
_currentPrincipal.IsInRole(
(SecurityIdentifier)currentRule.IdentityReference)) {
if (currentRule.AccessControlType.Equals(AccessControlType.Deny)) {
if ((currentRule.FileSystemRights & right) == right) {
if (currentRule.IsInherited) {
inheritedDeny = true;
} else { // Non inherited "deny" takes overall precedence.
return false;
}
}
} else if (currentRule.AccessControlType
.Equals(AccessControlType.Allow)) {
if ((currentRule.FileSystemRights & right) == right) {
if (currentRule.IsInherited) {
inheritedAllow = true;
} else {
allow = true;
}
}
}
}
}
if (allow) { // Non inherited "allow" takes precedence over inherited rules.
return true;
}
return inheritedAllow && !inheritedDeny;
}
}
However, I made the experience that this does not always work on remote computers as you will not always have the right to query the file access rights there. The solution in that case is to try; possibly even by just trying to create a temporary file, if you need to know the access right before working with the "real" files.
This will remove empty lines or lines with only whitespace characters (tabs/spaces).

The following will display all 3 buttons on the same line provided there is enough horizontal space to display them:
<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
// Note the lack of unnecessary divs, floats, etc.
The only reason the buttons wouldn't display inline is if they have had display:block applied to them within your css.
You can do it like this:
//HTML BUTTON
<button type="button" onclick="disableAll()">Disable</button>
//Jquery function
function disableAll() {
//DISABLE ALL FIELDS THAT ARE NOT DISABLED
$('form').find(':input:not(:disabled)').prop('disabled', true);
//ENABLE ALL FIELDS THAT DISABLED
//$('form').find(':input(:disabled)').prop('disabled', false);
}
You can do:

return false;

The corners are actually in .modal-content
So you may try this:

}
.modal-body {

}
If you change the color of the header or footer, the rounded corners will be drawn over.
With your question edit, I see your problem. Let's say the current directory is /home/yourname
... in this case, your command below:
sed 's/xxx/'$PWD'/'
will be expanded to
sed `s/xxx//home/yourname//
which is not valid. You need to put a \
character in front of each /
in your $PWD if you want to do this.

It's old but thought I'd add my two cents... Not sure if it will work but try using a KeyValuePair:
List<KeyValuePair<?, ?>> LinkList = new List<KeyValuePair<?, ?>>();
LinkList.Add(new KeyValuePair<?, ?>(Object, Object));
You'll end up with something like this:
LinkList[0] = <Object, Object>
LinkList[1] = <Object, Object>
LinkList[2] = <Object, Object>
and so on...

My Comments:
When I see the output, the output is mixed with One, Two, Three which are the thread names and they run simultaneously. I am not sure when you say thread is not running by main method.
Not sure if I understood your question or not. But I m putting my answer what I could understand, hope it can help you.
1) Then you created the object, it called the constructor, in construct it has start method which started the thread and executed the contents written inside run() method.
So as you created 3 objects (3 threads - one, two, three), all 3 threads started executing simultaneously.
2) Join and Synchronization They are 2 different things, Synchronization is when there are multiple threads sharing a common resource and one thread should use that resource at a time. E.g. Threads such as DepositThread, WithdrawThread etc. do share a common object as BankObject. So while DepositThread is running, the WithdrawThread will wait if they are synchronized. wait(), notify(), notifyAll() are used for inter-thread communication. Plz google to know more.
about Join(), it is when multiple threads are running, but you join. e.g. if there are two thread t1 and t2 and in multi-thread env they run, the output would be: t1-0 t2-0 t1-1 t2-1 t1-2 t2-2
and we use t1.join(), it would be: t1-0 t1-1 t1-2 t2-0 t2-1 t2-2
This is used in realtime when sometimes you don't mix up the thread in certain conditions and one depends another to be completed (not in shared resource), so you can call the join() method.
Note that from Netbeans 8 there is no Run panel in the project Properties.
To do what you want I simply add the following line (example setting the locale) in my project's properties file:
run.args.extra=--locale fr:FR
SELECT @var = col1,
@var2 = col2
FROM Table
Here is some interesting information about SET / SELECT
- SET is the ANSI standard for variable assignment, SELECT is not.
- SET can only assign one variable at a time, SELECT can make multiple assignments at once.
- If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
- When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
- As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
A complete solution is here

Both functions are wrong. First of all function initNode
has a confusing name. It should be named as for example initList
and should not do the task of addNode. That is, it should not add a value to the list.
In fact, there is not any sense in function initNode, because the initialization of the list can be done when the head is defined:
Node *head = nullptr;
or
Node *head = NULL;
So you can exclude function initNode
from your design of the list.
Also in your code there is no need to specify the elaborated type name for the structure Node
that is to specify keyword struct before name Node
.
Function addNode
shall change the original value of head. In your function realization you change only the copy of head passed as argument to the function.
The function could look as:
void addNode(Node **head, int n)
{
Node *NewNode = new Node {n, *head};
*head = NewNode;
}
Or if your compiler does not support the new syntax of initialization then you could write
void addNode(Node **head, int n)
{
Node *NewNode = new Node;
NewNode->x = n;
NewNode->next = *head;
*head = NewNode;
}
Or instead of using a pointer to pointer you could use a reference to pointer to Node. For example,
void addNode(Node * &head, int n)
{
Node *NewNode = new Node {n, head};
head = NewNode;
}
Or you could return an updated head from the function:
Node * addNode(Node *head, int n)
{
Node *NewNode = new Node {n, head};
head = NewNode;
return head;
}
And in main
write:
head = addNode(head, 5);

setattr( targetObj, method.__name__, MethodType(method, targetObj, type(method)) )

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

Shell works for me.
Simply to say, Shell is the same as you run a shell script.
Notes:
The following example shows an error in shell, but it's success at the end of the execution.
- name: test shell with an error
become: no
shell: |
rm -f /test1 # This should be an error.
echo "test2"
echo "test1"
echo "test3" # success
This example shows stopinng shell with exit 1 error.
- name: test shell with exit 1
become: no
shell: |
rm -f /test1 # This should be an error.
echo "test2"
exit 1 # this stops ansible due to returning an error
echo "test1"
echo "test3" # success

Once you compute the sum of the two sets of word vectors, you should take the cosine between the vectors, not the diff. The cosine can be computed by taking the dot product of the two vectors normalized. Thus, the word count is not a factor.
Here is an implementation of the Fisher-Yates shuffle that allows specification of the number of elements to return; hence, it is not necessary to first sort the whole collection before taking your desired number of elements.
The sequence of swapping elements is reversed from default; and proceeds from the first element to the last element, so that retrieving a subset of the collection yields the same (partial) sequence as shuffling the whole collection:
collection.TakeRandom(5).SequenceEqual(collection.Shuffle().Take(5)); // true
This algorithm is based on Durstenfeld's (modern) version of the Fisher-Yates shuffle on Wikipedia.
public static IList<T> TakeRandom<T>(this IEnumerable<T> collection, int count, Random random) => shuffle(collection, count, random);
public static IList<T> Shuffle<T>(this IEnumerable<T> collection, Random random) => shuffle(collection, null, random);
private static IList<T> shuffle<T>(IEnumerable<T> collection, int? take, Random random)
{
var a = collection.ToArray();
var n = a.Length;
if (take <= 0 || take > n) throw new ArgumentException("Invalid number of elements to return.");
var end = take ?? n;
for (int i = 0; i < end; i++)
{
var j = random.Next(i, n);
(a[i], a[j]) = (a[j], a[i]);
}
if (take.HasValue) return new ArraySegment<T>(a, 0, take.Value);
return a;
}

This can happen if you have a newline (or other control character) in a JSON string literal.

If you are the one producing the data, replace actual newlines with escaped ones "\\n"
when creating your string literals.
{"foo": "bar\nbaz"}
For small scripts an optional way to make it readable is to use a variable like this:
awk -v fmt="'%s'\n" '{printf fmt, $1}'
I found it conveninet in a case where I had to produce many times the single-quote character in the output and the \047 were making it totally unreadable
Collections are a resource so /appointments is fine as the resource.
Collections also typically offer filters via the querystring which is essentially what users=id1,id2... is.
So,
/appointments?users=id1,id2
is fine as a filtered RESTful resource.

In Sql when any word contain @ sign it means it is variable and we use this variable to set value in it and use it on number area on the same sql script because it is only restricted on the single script while you can declare lot of variables of same type and name on many script. We use this variable in stored procedure lot because stored procedure are pre-compiled queries and we can pass values in these variable from script, desktop and websites for further information read Declare Local Variable, Sql Stored Procedure and sql injections.
Also read Protect from sql injection it will guide how you can protect your database.

The issue for me was that NuGet couldn't automatically get/update the packages because the full file path would be too large. Fixed by moving my solution to a folder in my Documents instead of a deeply nested folder.
Then can right-click on solution and select "Restore NuGet Packages" (which probably isn't necessary if you just build it and let it do it for you), and then select "Manage NuGet Packages for Solution" to get all the packages updated to the latest version.

You can also enable tracing using WMI. More info: https://msdn.microsoft.com/en-us/library/ms730064(v=vs.110).aspx
In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )
py -2 -m pip install pyfora
You can use "data-123".replace('data-','');
, as mentioned, but as replace()
only replaces the FIRST instance of the matching text, if your string was something like "data-123data-"
then
"data-123data-".replace('data-','');
will only replace the first matching text. And your output will be "123data-"
So if you want all matches of text to be replaced in string you have to use a regular expression with the g
flag like that:
"data-123data-".replace(/data-/g,'');
And your output will be "123"
Set IFS to ,:
sorin@sorin:~$ IFS=',' ;for i in `echo "Hello,World,Questions,Answers,bash shell,script"`; do echo $i; done
Hello
World
Questions
Answers
bash shell
script
sorin@sorin:~$
XmlSerializer xs = new XmlSerializer(typeof(User), new XmlRootAttribute("yourRootName"));
Try an simple loop:
var repeat = [], tmp, i = 0;
while(i < values.length){
repeat.indexOf(tmp = values[i++].name) > -1 ? values.pop(i--) : repeat.push(tmp)
}
Either directly in form parameters or
string controlName = this.Request.Params.Get("__EVENTTARGET");
Edit: To check if a control caused a postback (manually):
// input Image with name="imageName"
if (this.Request["imageName"+".x"] != null) ...;//caused postBack
// Other input with name="name"
if (this.Request["name"] != null) ...;//caused postBack
You could also iterate through all the controls and check if one of them caused a postBack using the above code.
Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.
So, you should use ready in a bit different way
$.ready(function() {
createGrid();
});
This is in case when you dont use AJAX to load your div
Without explicitly defining the height
I determined I need to apply the flex
value to the parent and grandparent div
elements...
<div style="display: flex;">
<div style="display: flex;">
<img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>
If you're using a single element (e.g. dead-centered text in a single flex
element) use the following:
align-items: center;
display: flex;
justify-content: center;

new flutter sdk since after integration of web and desktop support you need to specify individually like this
TextFormField(
cursorColor: Colors.black,
keyboardType: inputType,
decoration: new InputDecoration(
border: InputBorder.none,
focusedBorder: InputBorder.none,
enabledBorder: InputBorder.none,
errorBorder: InputBorder.none,
disabledBorder: InputBorder.none,
contentPadding:
EdgeInsets.only(left: 15, bottom: 11, top: 11, right: 15),
hintText: "Hint here"),
)
This is what you need :)
$('._someDropDown').live('change', function(e) {
console.log(e.target.options[e.target.selectedIndex].text);
});
For new jQuery use on
$(document).on('change', '._someDropDown', function(e) {
console.log(this.options[e.target.selectedIndex].text);
});
Most importantly you need to mount the drive
net use z: \\yourserver\sharename
Of course, you need to make sure that the account the batch file runs under has permission to access the share. If you are doing this by using a Scheduled Task, you can choose the account by selecting the task, then:
"When running the task, use the following user account:" That's on Windows 7, it might be slightly different on different versions of Windows.
Then run your batch script with the following changes
copy "z:\FolderName" "C:\TEST_BACKUP_FOLDER"
If you have just a pair of brackets ( []
) in your string, you can use indexOf()
:
String str = "ABC[ This is the text to be extracted ]";
String result = str.substring(str.indexOf("[") + 1, str.indexOf("]"));
Why not just using scanf("%i") and check its return?
You cannot run it on main thread instead use handlers, async or working threads . A sample code is available here and read article over room library here : Android's Room Library
/**
* Insert and get data using Database Async way
*/
AsyncTask.execute(new Runnable() {
@Override
public void run() {
// Insert Data
AppDatabase.getInstance(context).userDao().insert(new User(1,"James","Mathew"));
// Get Data
AppDatabase.getInstance(context).userDao().getAllUsers();
}
});
If you want to run it on main thread which is not preferred way .
You can use this method to achieve on main thread Room.inMemoryDatabaseBuilder()
I have tried several solutions mentioned over web, unfortunately without any success. In my project, I have two interfaces(xml/json) for each service. Adding mex endpoints or binding configurations did not helped at all. But, I have noticed, I get this error only when running project with *.svc.cs or *.config file focused. When I run project with IService.cs file focused (where interfaces are defined), service is added without any errors. This is really strange and in my opinion conclusion is bug in Visual Studio 2013. I reproduced same behaviour on several machines(even on Windows Server machine). Hope this helps someone.
It's called a shebang. In unix-speak, # is called sharp (like in music) or hash (like hashtags on twitter), and ! is called bang. (You can actually reference your previous shell command with !!, called bang-bang). So when put together, you get haSH-BANG, or shebang.
The part after the #! tells Unix what program to use to run it. If it isn't specified, it will try with bash (or sh, or zsh, or whatever your $SHELL variable is) but if it's there it will use that program. Plus, # is a comment in most languages, so the line gets ignored in the subsequent execution.
new Uri(Request.RequestUri, RequestContext.VirtualPathRoot)
I just had this error now in server only and the solution was to set a maxItemsInObjectGraph
attribute in wcf web.config
under <behavior>
tag:
<dataContractSerializer maxItemsInObjectGraph="2147483646"/>
Here's another, perhaps more familiar-looking way to do it:
for i in (0..10).step(2) do
puts i
end
Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don't already have one.
If you do not want to install and have a separate zookeeper server, you can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance.
Starting the single-node Zookeeper instance:
bin/zookeeper-server-start.sh config/zookeeper.properties
Starting the Kafka Server:
bin/kafka-server-start.sh config/server.properties
Listing the Topics available in Kafka:
bin/kafka-topics.sh --list --zookeeper localhost:2181

There is an implementation in my TypeScript utilities based on JavaScript GUID generators.
Here is the code:
class Guid {_x000D_
static newGuid() {_x000D_
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {_x000D_
var r = Math.random() * 16 | 0,_x000D_
v = c == 'x' ? r : (r & 0x3 | 0x8);_x000D_
return v.toString(16);_x000D_
});_x000D_
}_x000D_
}_x000D_
_x000D_
// Example of a bunch of GUIDs_x000D_
for (var i = 0; i < 100; i++) {_x000D_
var id = Guid.newGuid();_x000D_
console.log(id);_x000D_
}
_x000D_
Please note the following:
C# GUIDs are guaranteed to be unique. This solution is very likely to be unique. There is a huge gap between "very likely" and "guaranteed" and you don't want to fall through this gap.
JavaScript-generated GUIDs are great to use as a temporary key that you use while waiting for a server to respond, but I wouldn't necessarily trust them as the primary key in a database. If you are going to rely on a JavaScript-generated GUID, I would be tempted to check a register each time a GUID is created to ensure you haven't got a duplicate (an issue that has come up in the Chrome browser in some cases).
I did it in this way.
In tasks/main.yml
- name: template test
template:
src=myTemplateFile.j2
dest={{item}}
with_dict: some_dict
and in vars/main.yml
some_dict:
/path/to/dest1:
var1: 1
var2: 2
/path/to/dest2:
var1: 3
var2: 4
and in templates/myTemplateFile.j2
some_var = {{ item.value.var1 }}
some_other_var = {{ item.value.var2 }}
Hope this solves your problem.
import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"
The re.sub
function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>'
) and replacing them with nothing (''
).
The ?
is used in re
for non-greedy searches.

If they are separate classes you can do something like the following:
class A
{
private $name;
public function __construct()
{
$this->name = 'Some Name';
}
public function getName()
{
return $this->name;
}
}
class B
{
private $a;
public function __construct(A $a)
{
$this->a = $a;
}
function getNameOfA()
{
return $this->a->getName();
}
}
$a = new A();
$b = new B($a);
$b->getNameOfA();
What I have done in this example is first create a new instance of the A
class. And after that I have created a new instance of the B
class to which I pass the instance of A
into the constructor. Now B
can access all the public members of the A
class using $this->a
.
Also note that I don't instantiate the A
class inside the B
class because that would mean I tighly couple the two classes. This makes it hard to:
B
classA
class for another classYou can do this also:
$("a.markAsDone").click(function (event) {
event.preventDefault();
$.ajax({
type: "post",
dataType: "html",
url: $(this).attr("rel"),
data: $('<form>@Html.AntiForgeryToken()</form>').serialize(),
success: function (response) {
// ....
}
});
});
This is using Razor
, but if you're using WebForms
syntax you can just as well use <%= %>
tags
My guess is it's an encoding problem, for instance your file is UTF-8 but SQL will not read it the way it should, so it attempts to insert 100ÿ or something along these lines into your table.
Possible fixes:
Code samples:
1.
BULK INSERT myTable FROM 'c:\Temp\myfile.csv' WITH (
FIELDTERMINATOR = '£',
ROWTERMINATOR = '\n',
CODEPAGE = 'ACP' -- ACP corresponds to ANSI, also try UTF-8 or 65001 for Unicode
);
2.
get-content "myfile.csv" | Set-content -Path "myfile.csv" -Encoding String
# String = ANSI, also try Ascii, Oem, Unicode, UTF7, UTF8, UTF32
You can use qTip for this; However you'd have to code a little for launching it on mouseover event; And in case you want a default watermark on your text fields, you'd have to use the watermark plugin...
I realized that this leads to lot of repetitive code; So I wrote a plugin on top of qTip that makes it really easy to attach informational popup to form fields. You can check it out here: https://bitbucket.org/gautamtandon/jquery.attachinfo
Hope this helps.
One of the variables has not been given any value, thus it is a NoneType. You'll have to look into why this is, it's probably a simple logic error on your part.
