What about this? Change the return type from T
to Nullable<T>
public static Nullable<T> GetQueryString<T>(string key) where T : struct, IConvertible
{
T result = default(T);
if (String.IsNullOrEmpty(HttpContext.Current.Request.QueryString[key]) == false)
{
string value = HttpContext.Current.Request.QueryString[key];
try
{
result = (T)Convert.ChangeType(value, typeof(T));
}
catch
{
//Could not convert. Pass back default value...
result = default(T);
}
}
return result;
}
Just for completeness, the following is a Java solution. I am certain the same could be done in C# as well. It avoids having to specify the type anywhere in code - instead, you specify it in the strings you are trying to parse.
The problem is that there isn't any way to know which enumeration the String might match - so the answer is to solve that problem.
Instead of accepting just the string value, accept a String that has both the enumeration and the value in the form "enumeration.value". Working code is below - requires Java 1.8 or later. This would also make the XML more precise as in you would see something like color="Color.red" instead of just color="red".
You would call the acceptEnumeratedValue() method with a string containing the enum name dot value name.
The method returns the formal enumerated value.
import java.util.HashMap;
import java.util.Map;
import java.util.function.Function;
public class EnumFromString {
enum NumberEnum {One, Two, Three};
enum LetterEnum {A, B, C};
Map<String, Function<String, ? extends Enum>> enumsByName = new HashMap<>();
public static void main(String[] args) {
EnumFromString efs = new EnumFromString();
System.out.print("\nFirst string is NumberEnum.Two - enum is " + efs.acceptEnumeratedValue("NumberEnum.Two").name());
System.out.print("\nSecond string is LetterEnum.B - enum is " + efs.acceptEnumeratedValue("LetterEnum.B").name());
}
public EnumFromString() {
enumsByName.put("NumberEnum", s -> {return NumberEnum.valueOf(s);});
enumsByName.put("LetterEnum", s -> {return LetterEnum.valueOf(s);});
}
public Enum acceptEnumeratedValue(String enumDotValue) {
int pos = enumDotValue.indexOf(".");
String enumName = enumDotValue.substring(0, pos);
String value = enumDotValue.substring(pos + 1);
Enum enumeratedValue = enumsByName.get(enumName).apply(value);
return enumeratedValue;
}
}
Check the URL it should be using https rather than http protocol.
In my case changing http to https in the URL solved it.

If you are looking for a way to "mount" files, like -v
for docker run
, you can now use the --secret
flag for docker build
echo 'WARMACHINEROX' > mysecret.txt
docker build --secret id=mysecret,src=mysecret.txt .
And inside your Dockerfile you can now access this secret
# syntax = docker/dockerfile:1.0-experimental
FROM alpine
# shows secret from default secret location:
RUN --mount=type=secret,id=mysecret cat /run/secrets/mysecret
# shows secret from custom secret location:
RUN --mount=type=secret,id=mysecret,dst=/foobar cat /foobar
More in-depth information about --secret available on Docker Docs
One can also do this with pylab and xticks

plt.plot(x,y, 'r')
plt.xticks(x, labels, rotation='vertical')
plt.show()

Let me answer this question thoroughly, because it's been a source of pain for me for several years and very few people really understand the problem and why it's important for it to be solved. If I were at all responsible for the CSS spec I'd be embarrassed, frankly, for having not addressed this in the last decade.
The Problem
You need to insert markup into an HTML document, and it needs to look a specific way. Furthermore, you do not own this document, so you cannot change existing style rules. You have no idea what the style sheets could be, or what they may change to.
Use cases for this are when you are providing a displayable component for unknown 3rd party websites to use. Examples of this would be:
Simplest Fix
Put everything in an iframe. This has it's own set of limitations:
If your content can fit into a box, you can get around problem #1 by having your content write an iframe and explicitly set the content, thus skirting around the issue, since the iframe and document will share the same domain.
CSS Solution
I've search far and wide for the solution to this, but there are unfortunately none. The best you can do is explicitly override all possible properties that can be overridden, and override them to what you think their default value should be.
Even when you override, there is no way to ensure a more targeted CSS rule won't override yours. The best you can do here is to have your override rules target as specifically as possible and hope the parent document doesn't accidentally best it: use an obscure or random ID on your content's parent element, and use !important on all property value definitions.
I'm guessing that Clients.Case_Number
and/or Staff.Emp_ID
are not exactly the same data type as Clients_has_Staff.Clients_Case_Number
and Clients_has_Staff.Staff_Emp_ID
.
Perhaps the columns in the parent tables are INT UNSIGNED
?
They need to be exactly the same data type in both tables.
I found that the only option that worked for me was
font-size:0;
I was also using overflow
and white-space: nowrap;
float: left;
seems to mess things up
You don't need to fiddle around with any command :)
Once the XCode is updated, open the Xcode IDE program. Please accept terms and conditions.
You are all set to go :))
$mystring = "this is the text I would like to truncate";
// Pass your variable to the function
$mystring = truncate($mystring);
// Truncated tring printed out;
echo $mystring;
//truncate text function
public function truncate($text) {
//specify number fo characters to shorten by
$chars = 25;
$text = $text." ";
$text = substr($text,0,$chars);
$text = substr($text,0,strrpos($text,' '));
$text = $text."...";
return $text;
}
Delete node_modules and package-lock.json, and then run npm install. It worked perfectly here(run command below inside project root):
rm -rf node_modules && rm ./package-lock.json && npm install
Something the original answer didn't have. I added some more code to make it bullet proof.
ServicePointManager.Expect100Continue = true;
ServicePointManager.DefaultConnectionLimit = 9999;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;
You can even set a separate right margin for HTML. Under the specified path:
File >> Settings >> Editor >> Code Style >> HTML >> Other Tab >> Right margin (columns)
This is very useful because generally HTML and JS may be usually long in one line than Python. :)
When using System.Net.WebRequest your application will negotiate with the server to determine the highest TLS version that both your application and the server support, and use this. You can see more details on how this works here:
http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_handshake
If the server doesn't support TLS it will fallback to SSL, therefore it could potentially fallback to SSL3. You can see all of the versions that .NET 4.5 supports here:
http://msdn.microsoft.com/en-us/library/system.security.authentication.sslprotocols(v=vs.110).aspx
In order to prevent your application being vulnerable to POODLE, you can disable SSL3 on the machine that your application is running on by following this explanation:
Polymorphism literally means, multiple shapes. (or many form) : Object from different classes and same name method , but workflows are different. A simple example would be:
Consider a person X.
He is only one person but he acts as many. You may ask how:
He is a son to his mother. A friend to his friends. A brother to his sister.
Try including this on your style sheet:
html {
font-size: min(max(16px, 4vw), 22px);
}

I think based on the documentation of the @Before
and @After
the right conclusion is to give the methods unique names. I use the following pattern in my tests:
public abstract class AbstractBaseTest {
@Before
public final void baseSetUp() { // or any other meaningful name
System.out.println("AbstractBaseTest.setUp");
}
@After
public final void baseTearDown() { // or any other meaningful name
System.out.println("AbstractBaseTest.tearDown");
}
}
and
public class Test extends AbstractBaseTest {
@Before
public void setUp() {
System.out.println("Test.setUp");
}
@After
public void tearDown() {
System.out.println("Test.tearDown");
}
@Test
public void test1() throws Exception {
System.out.println("test1");
}
@Test
public void test2() throws Exception {
System.out.println("test2");
}
}
give as a result
AbstractBaseTest.setUp
Test.setUp
test1
Test.tearDown
AbstractBaseTest.tearDown
AbstractBaseTest.setUp
Test.setUp
test2
Test.tearDown
AbstractBaseTest.tearDown
Advantage of this approach: Users of the AbstractBaseTest class cannot override the setUp/tearDown methods by accident. If they want to, they need to know the exact name and can do it.
(Minor) disadvantage of this approach: Users cannot see that there are things happening before or after their setUp/tearDown. They need to know that these things are provided by the abstract class. But I assume that's the reason why they use the abstract class
Here I have used omit() for the respective 'key' which you want to remove... by using the Lodash library:
var credentials = [{
fname: "xyz",
lname: "abc",
age: 23
}]
let result = _.map(credentials, object => {
return _.omit(object, ['fname', 'lname'])
})
console.log('result', result)
You can access the USB drive by its drive letter. To know the drive letter you can run this command:
C:\>wmic logicaldisk where drivetype=2 get deviceid, volumename, description
From here you will get the drive letter (Device ID) of your USB drive.
For example if its F: then run the following command in command prompt to see its contents:
C:\> F:
F:\> dir
var values = [];
var count = 0;
$("#tblName").on("click", "tbody tr", function (event) {
$(this).find("td").each(function () {
values[count] = $(this).text();
count++;
});
});
Now values array contain all the cell values of that row can be used like values[0] first cell value of clicked row
for large numbers that display with scientific notation set format to just '#'
The answers that suggest using variations of $window.history.back()
have all missed a crucial part of the question: How to restore the application's state to the correct state-location as the history jumps (back/forward/refresh). With that in mind; please, read on.
Yes, it is possible to have the browser back/forward (history) and refresh whilst running a pure ui-router
state-machine but it takes a bit of doing.
You need several components:
Unique URLs. The browser only enables the back/forward buttons when you change urls, so you must generate a unique url per visited state. These urls need not contain any state information though.
A Session Service. Each generated url is correlated to a particular state so you need a way to store your url-state pairs so that you can retrieve the state information after your angular app has been restarted by back / forward or refresh clicks.
A State History. A simple dictionary of ui-router states keyed by unique url. If you can rely on HTML5 then you can use the HTML5 History API, but if, like me, you can't then you can implement it yourself in a few lines of code (see below).
A Location Service. Finally, you need to be able manage both ui-router state changes, triggered internally by your code, and normal browser url changes typically triggered by the user clicking browser buttons or typing stuff into the browser bar. This can all get a bit tricky because it is easy to get confused about what triggered what.
Here is my implementation of each of these requirements. I have bundled everything up into three services:
The Session Service
class SessionService
setStorage:(key, value) ->
json = if value is undefined then null else JSON.stringify value
sessionStorage.setItem key, json
getStorage:(key)->
JSON.parse sessionStorage.getItem key
clear: ->
@setStorage(key, null) for key of sessionStorage
stateHistory:(value=null) ->
@accessor 'stateHistory', value
# other properties goes here
accessor:(name, value)->
return @getStorage name unless value?
@setStorage name, value
angular
.module 'app.Services'
.service 'sessionService', SessionService
This is a wrapper for the javascript sessionStorage
object. I have cut it down for clarity here. For a full explanation of this please see: How do I handle page refreshing with an AngularJS Single Page Application
The State History Service
class StateHistoryService
@$inject:['sessionService']
constructor:(@sessionService) ->
set:(key, state)->
history = @sessionService.stateHistory() ? {}
history[key] = state
@sessionService.stateHistory history
get:(key)->
@sessionService.stateHistory()?[key]
angular
.module 'app.Services'
.service 'stateHistoryService', StateHistoryService
The StateHistoryService
looks after the storage and retrieval of historical states keyed by generated, unique urls. It is really just a convenience wrapper for a dictionary style object.
The State Location Service
class StateLocationService
preventCall:[]
@$inject:['$location','$state', 'stateHistoryService']
constructor:(@location, @state, @stateHistoryService) ->
locationChange: ->
return if @preventCall.pop('locationChange')?
entry = @stateHistoryService.get @location.url()
return unless entry?
@preventCall.push 'stateChange'
@state.go entry.name, entry.params, {location:false}
stateChange: ->
return if @preventCall.pop('stateChange')?
entry = {name: @state.current.name, params: @state.params}
#generate your site specific, unique url here
url = "/#{@state.params.subscriptionUrl}/#{Math.guid().substr(0,8)}"
@stateHistoryService.set url, entry
@preventCall.push 'locationChange'
@location.url url
angular
.module 'app.Services'
.service 'stateLocationService', StateLocationService
The StateLocationService
handles two events:
locationChange. This is called when the browsers location is changed, typically when the back/forward/refresh button is pressed or when the app first starts or when the user types in a url. If a state for the current location.url exists in the StateHistoryService
then it is used to restore the state via ui-router's $state.go
.
stateChange. This is called when you move state internally. The current state's name and params are stored in the StateHistoryService
keyed by a generated url. This generated url can be anything you want, it may or may not identify the state in a human readable way. In my case I am using a state param plus a randomly generated sequence of digits derived from a guid (see foot for the guid generator snippet). The generated url is displayed in the browser bar and, crucially, added to the browser's internal history stack using @location.url url
. Its adding the url to the browser's history stack that enables the forward / back buttons.
The big problem with this technique is that calling @location.url url
in the stateChange
method will trigger the $locationChangeSuccess
event and so call the locationChange
method. Equally calling the @state.go
from locationChange
will trigger the $stateChangeSuccess
event and so the stateChange
method. This gets very confusing and messes up the browser history no end.
The solution is very simple. You can see the preventCall
array being used as a stack (pop
and push
). Each time one of the methods is called it prevents the other method being called one-time-only. This technique does not interfere with the correct triggering of the $ events and keeps everything straight.
Now all we need to do is call the HistoryService
methods at the appropriate time in the state transition life-cycle. This is done in the AngularJS Apps .run
method, like this:
Angular app.run
angular
.module 'app', ['ui.router']
.run ($rootScope, stateLocationService) ->
$rootScope.$on '$stateChangeSuccess', (event, toState, toParams) ->
stateLocationService.stateChange()
$rootScope.$on '$locationChangeSuccess', ->
stateLocationService.locationChange()
Generate a Guid
Math.guid = ->
s4 = -> Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1)
"#{s4()}#{s4()}-#{s4()}-#{s4()}-#{s4()}-#{s4()}#{s4()}#{s4()}"
With all this in place, the forward / back buttons and the refresh button all work as expected.
If anyone is strugling with the same problem I solved it by adding @EntityScan
in my main class. Just add your model package to the basePackages property.
Try
$ yum provides ld-linux.so.2
$ yum update
$ yum install glibc.i686 libfreetype.so.6 libfontconfig.so.1 libstdc++.so.6
Hope this clears out.
This is a take on Mike W's answer:
internal static DateTime GetPreviousMonth(bool returnLastDayOfMonth)
{
DateTime firstDayOfThisMonth = DateTime.Today.AddDays( - ( DateTime.Today.Day - 1 ) );
DateTime lastDayOfLastMonth = firstDayOfThisMonth.AddDays (-1);
if (returnLastDayOfMonth) return lastDayOfLastMonth;
return firstDayOfThisMonth.AddMonths(-1);
}
You can call it like so:
dateTimePickerFrom.Value = GetPreviousMonth(false);
dateTimePickerTo.Value = GetPreviousMonth(true);
The Best & Easiest solution:-
SELECT
max(salary)
FROM
salary
WHERE
salary < (
SELECT
max(salary)
FROM
salary
);
Depth first search with backtracking should work here. Keep an array of boolean values to keep track of whether you visited a node before. If you run out of new nodes to go to (without hitting a node you have already been), then just backtrack and try a different branch.
The DFS is easy to implement if you have an adjacency list to represent the graph. For example adj[A] = {B,C} indicates that B and C are the children of A.
For example, pseudo-code below. "start" is the node you start from.
dfs(adj,node,visited):
if (visited[node]):
if (node == start):
"found a path"
return;
visited[node]=YES;
for child in adj[node]:
dfs(adj,child,visited)
visited[node]=NO;
Call the above function with the start node:
visited = {}
dfs(adj,start,visited)
The accepted answer is deprecated in version 28 so here is the solution that I am using in my project.
Returns connection type. false: no Internet Connection; true: mobile data || wifi
public static boolean isNetworkConnected(Context context) {
boolean result = false;
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (cm != null) {
NetworkCapabilities capabilities = cm.getNetworkCapabilities(cm.getActiveNetwork());
if (capabilities != null) {
if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
result = true;
} else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
result = true;
}
}
}
} else {
if (cm != null) {
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) {
// connected to the internet
if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
result = true;
} else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
result = true;
}
}
}
}

You may need to know the status during the file download or use credentials before making the request.
Here is an example that covers these options:
Uri ur = new Uri("http://remotehost.do/images/img.jpg");
using (WebClient client = new WebClient()) {
//client.Credentials = new NetworkCredential("username", "password");
String credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes("Username" + ":" + "MyNewPassword"));
client.Headers[HttpRequestHeader.Authorization] = $"Basic {credentials}";
client.DownloadProgressChanged += WebClientDownloadProgressChanged;
client.DownloadDataCompleted += WebClientDownloadCompleted;
client.DownloadFileAsync(ur, @"C:\path\newImage.jpg");
}
And the callback's functions implemented as follows:
void WebClientDownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
}
void WebClientDownloadCompleted(object sender, DownloadDataCompletedEventArgs e)
{
Console.WriteLine("Download finished!");
}
(Ver 2) - Lambda notation: other possible option for handling the events
client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(delegate(object sender, DownloadProgressChangedEventArgs e) {
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
});
client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(delegate(object sender, DownloadDataCompletedEventArgs e){
Console.WriteLine("Download finished!");
});
(Ver 3) - We can do better
client.DownloadProgressChanged += (object sender, DownloadProgressChangedEventArgs e) =>
{
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
};
client.DownloadDataCompleted += (object sender, DownloadDataCompletedEventArgs e) =>
{
Console.WriteLine("Download finished!");
};
(Ver 4) - Or
client.DownloadProgressChanged += (o, e) =>
{
Console.WriteLine($"Download status: {e.ProgressPercentage}%.");
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
};
client.DownloadDataCompleted += (o, e) =>
{
Console.WriteLine("Download finished!");
};
It is not natively possible to run Android application under iOS (which powers iPhone, iPad, iPod, etc.)
This is because both runtime stacks use entirely different approaches. Android runs Dalvik (a "variant of Java") bytecode packaged in APK files while iOS runs Compiled (from Obj-C) code from IPA files. Excepting time/effort/money and litigations (!), there is nothing inherently preventing an Android implementation on Apple hardware, however.
It looks to package a small Dalvik VM with each application and targeted towards developers.
See iPhoDroid:
Looks to be a dual-boot solution for 2G/3G jailbroken devices. Very little information available, but there are some YouTube videos.
See iAndroid:
iAndroid is a new iOS application for jailbroken devices that simulates the Android operating system experience on the iPhone or iPod touch. While it’s still very far from completion, the project is taking shape.
I am not sure the approach(es) it uses to enable this: it could be emulation or just a simulation (e.g. "looks like"). The requirement of being jailbroken makes it sound like emulation might be used ..
See BlueStacks, per the Holo Dev's comment:
It looks to be an "Android App Player" for OS X (and Windows). However, afaik, it does not [currently] target iOS devices ..
YMMV
Instead of including locale and all that fancy stuff, if you know for FACT your string is convertible just do this:
#include <iostream>
#include <string>
using namespace std;
int main()
{
wstring w(L"bla");
string result;
for(char x : w)
result += x;
cout << result << '\n';
}

Form
isn't included in laravel
5.0 as it was on 4.0, steps to include it:
Begin by installing laravelcollective/html
package through Composer
. Edit your project's composer.json
file to require:
"require": {
"laravelcollective/html": "~5.0"
}
Next, update composer
from the Terminal:
composer update
Next, add your new provider to the providers
array of config/app.php
:
'providers' => [
// ...
'Collective\Html\HtmlServiceProvider',
// ...
],
Finally, add two class aliases to the aliases
array of config/app.php
:
'aliases' => [
// ...
'Form' => 'Collective\Html\FormFacade',
'Html' => 'Collective\Html\HtmlFacade',
// ...
],
At this point, Form
should be working
Update Laravel 5.8
(2019-04-05):
In Laravel 5.8
, the providers
in the config/app.php
can be declared as:
Collective\Html\HtmlServiceProvider::class,
instead of:
'Collective\Html\HtmlServiceProvider',
This notation is the same for the aliases.
As of now, you can only store string values in localStorage. You'll need to serialize the array object and then store it in localStorage.
For example:
localStorage.setItem('session', a.join('|'));
or
localStorage.setItem('session', JSON.stringify(a));

You also can use some HTML5 attributes, some browsers might already take advantage of them (type="number" min="0"
).
Whatever you do, remember to re-check your inputs on the server side: you can never assume the client-side validation has been performed.
Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq
Save your JSON example to a file, say ex.json and then

in addition,if you try to use CustomActionBarTheme,make sure there is
<application android:theme="@style/CustomActionBarTheme" ... />
in AndroidManifest.xml
not
<application android:theme="@android:style/CustomActionBarTheme" ... />
This snippet of code will recursively convert that data to a single type (array or object) without the nested foreach loops. Hope it helps someone!
Once an Object is in array format you can use array_merge and convert back to Object if you need to.
abstract class Util {
public static function object_to_array($d) {
if (is_object($d))
$d = get_object_vars($d);
return is_array($d) ? array_map(__METHOD__, $d) : $d;
}
public static function array_to_object($d) {
return is_array($d) ? (object) array_map(__METHOD__, $d) : $d;
}
}
Procedural way
function object_to_array($d) {
if (is_object($d))
$d = get_object_vars($d);
return is_array($d) ? array_map(__FUNCTION__, $d) : $d;
}
function array_to_object($d) {
return is_array($d) ? (object) array_map(__FUNCTION__, $d) : $d;
}

You can change the background or ripple color of each Tab like this:
//set ripple color for each tab
for(int n = 0; n < mTabLayout.getTabCount(); n++){
View tab = ((ViewGroup)mTabLayout.getChildAt(0)).getChildAt(n);

JOptionPane.showInternalInputDialog probably does what you want. If not, it would be helpful to understand what it is missing.
To check for an exact match you would use num == line
. But line
has an end-of-line character \n
or \r\n
which will not be in num
since raw_input
strips the trailing newline. So it may be convenient to remove all whitespace at the end of line
with
line = line.rstrip()
with open("file.txt") as search:
for line in search:
line = line.rstrip() # remove '\n' at end of line
if num == line:
print(line )
Have you tried using the WebClient class?
you should be able to use
string result = "";
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = "application/json";
result = client.UploadString(url, "POST", json);
}
Console.WriteLine(result);

You can't compare against text
with the =
operator, but instead must used one of the comparison functions listed here. Also note the large warning box at the top of the page, it's important.
Just to add this to the list:
Uri.EscapeUriString("Hi there+Hello there") // Hi%20there+Hello%20there
Uri.EscapeDataString("Hi there+Hello there") // Hi%20there%2BHello%20there
See https://stackoverflow.com/a/34189188/98491
Usually you want to use EscapeDataString
which does it right.
Add new column to your table and perfrom the query:
UPDATE tbl SET combined = CONCAT(zipcode, ' - ', city, ', ', state)
Here's an example that shows how table(.)
(or, more closely matching your desired output, data.frame(table(.))
does what it sounds like you are asking for.
Note also how to share reproducible sample data in a way that others can copy and paste into their session.
Here's the (reproducible) sample data:
mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L),
MONTH.YEAR = c("JAN. 2012", "JAN. 2012",
"FEB. 2012", "FEB. 2012",
"MAR. 2012"),
VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)),
.Names = c("ID", "MONTH.YEAR", "VALUE"),
class = "data.frame", row.names = c(NA, -5L))
mydf
# ID MONTH.YEAR VALUE
# 1 110 JAN. 2012 1000
# 2 111 JAN. 2012 2000
# 3 121 FEB. 2012 3000
# 4 131 FEB. 2012 4000
# 5 141 MAR. 2012 5000
Here's the calculation of the number of rows per group, in two output display formats:
table(mydf$MONTH.YEAR)
#
# FEB. 2012 JAN. 2012 MAR. 2012
# 2 2 1
data.frame(table(mydf$MONTH.YEAR))
# Var1 Freq
# 1 FEB. 2012 2
# 2 JAN. 2012 2
# 3 MAR. 2012 1
===
and !==
are strict comparison operators:
JavaScript has both strict and type-converting equality comparison. For
strict
equality the objects being compared must have the same type and:
- Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
- Two numbers are strictly equal when they are numerically equal (have the same number value).
NaN
is not equal to anything, includingNaN
. Positive and negative zeros are equal to one another.- Two Boolean operands are strictly equal if both are true or both are false.
- Two objects are strictly equal if they refer to the same
Object
.Null
andUndefined
types are==
(but not===
). [I.e. (Null==Undefined
) istrue
but (Null===Undefined
) isfalse
]
Your database driver is missing. To solve the probelm
First install the driver
For ubuntu: For mysql database.
sudo apt-get install php5.6-mysql/php7.2-mysql
You also can search for other database systems.
You also can search for the driver:
sudo apt-cache search drivername
Then Run the cmd php artisan migrate
You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?
Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.
The following configs works on Cent OS 6 or earlier
As stated above first have to disable selinux.
Step 1 nano /etc/sysconfig/selinux
Make sure the file has this configurations
SELINUX=disabled
SELINUXTYPE=targeted
Then restart the system
Step 2
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
Step 3
sudo service iptables save
For Cent OS 7
step 1
firewall-cmd --zone=public --permanent --add-port=8080/tcp
Step 2
firewall-cmd --reload
[u'{email:[email protected],gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test1,gem:0}']
'u' denotes unicode characters. We can easily remove this with map function on the final list element
map(str, test)
Another way is when you are appending it to the list
test.append(str(a))
You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.

It is also not supported in JPA XML.
The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:
a) The IP/domain or port is incorrect
b) The IP/domain or port (i.e service) is down
c) The IP/domain is taking longer than your default timeout to respond
d) You have a firewall that is blocking requests or responses on whatever port you are using
e) You have a firewall that is blocking requests to that particular host
f) Your internet access is down
g) Your live-server is down i.e in case of "rest-API call".
Note that firewalls and port or IP blocking may be in place by your ISP
Be aware that a value of 1 equals 100% in Excel's interpretation. If you enter 5.66 and you want to show 5.66%, then AxGryndr's hack with the formatting will work, but it is a display format only and does not represent the true numeric value. If you want to use that percentage in further calculations, these calculations will return the wrong result unless you divide by 100 at calculation time.
The consistent and less error-prone way is to enter 0.0566 and format the number with the built-in percentage format. That way, you can easily calculate 5.6% of A1 by just multiplying A1 with the value.
The good news is that you don't need to go through the rigmarole of entering 0.0566 and then formatting as percent. You can simply type
5.66%
into the cell, including the percentage symbol, and Excel will take care of the rest and store the number correctly as 0.0566 if formatted as General.

MSI is an installer file which installs your program on the executing system.
Setup.exe is an application (executable file) which has msi file(s) as its one of the resources. Executing Setup.exe will in turn execute msi (the installer) which writes your application to the system.
Edit (as suggested in comment): Setup executable files don't necessarily have an MSI resource internally
If your arrays are character arrays(which seems to be the case), You need a strcat().
Your destination array should have enough space to accommodate the appended data though.
In C++, You are much better off using std::string and then you can use std::string::append()
In wamp/alias/mySite.conf, be careful to add a slash "/" at the end of the alias' adress :
Replace :

Or the index.php is not read correctly.
Use a post-build action in your project, and add the commands to copy the offending DLL. The post-build action are written as a batch script.
The output directory can be referenced as $(OutDir)
. The project directory is available as $(ProjDir)
. Try to use relative pathes where applicable, so that you can copy or move your project folder without breaking the post-build action.
+1 to PleaseStand and here is my other hack:
after searching and found that the "cross ajax request" could not get response headers from XHR object, I gave up. and use iframe instead.
1. <iframe style="display:none"></iframe>
2. $("iframe").attr("src", "http://the_url_you_want_to_access")
//this is my aim!!!
3. $("iframe").contents().find('#someID').html()
The response by @Miknash and @wolfgang gutierrez barrera was helpful to me. Only difference was I had to add rgbValue:
to the function call.
UIColorFromHex(rgbValue: 0xA6D632,alpha: 1 )
like so
This is the way which I use:
$float = 4.3;
$dec = ltrim(($float - floor($float)),"0."); // result .3
you didn't complete your try
statement. You need and except
in there too.
I think in this case you want something like this:
$(window).resize(resize=function resize(){ some code...}
Now u can call resize() within some other nested functions:
$(window).scroll(function(){ resize();}
Is this what you are looking for? Otherwise, let me know and I will remove this post.

This is due to IFS (Internal Field Separator) variable which contains newline.
$ cat xx1
1
2
$ A=`cat xx1`
$ echo $A
1 2
$ echo "|$IFS|"
|
|
A workaround is to reset IFS to not contain the newline, temporarily:
$ IFSBAK=$IFS
$ IFS=" "
$ A=`cat xx1` # Can use $() as well
$ echo $A
1
2
$ IFS=$IFSBAK
To REVERT this horrible change for IFS:
IFS=$IFSBAK
See section Attributes from documentation on directives.
observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.
In Log4j2, the "extras" lib is not mandatory any more. Also the configuration format has changed.
An example is provided in the Apache documentation

Aside from the particularities of how static method objects behave, there is a certain kind of beauty you can strike with them when it comes to organizing your module-level code.

It now becomes a bit more intuitive and self-documenting in which context certain components are meant to be used and it pans out ideally for naming distinct test cases as well as having a straightforward approach to how test modules map to actual modules under tests for purists.
I frequently find it viable to apply this approach to organizing a project's utility code. Quite often, people immediately rush and create a utils
package and end up with 9 modules of which one has 120 LOC and the rest are two dozen LOC at best. I prefer to start with this and convert it to a package and create modules only for the beasts that truly deserve them:
# utils.py
class socket(object):
@staticmethod
def check_if_port_available(port):
pass
@staticmethod
def get_free_port(port)
pass
class image(object):
@staticmethod
def to_rgb(image):
pass
@staticmethod
def to_cmyk(image):
pass
There are many ways to perform this task. Here is a simple one:
<Window x:Class="WPF_Demo1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="TestWindow"
Title="MainWindow" Height="500" Width="773">
<DockPanel LastChildFill="False">
<StackPanel DockPanel.Dock="Top" Background="Red" Margin="2">
<StackPanel Orientation="Horizontal" x:Name="spTopNav">
<ComboBox x:Name="cboBox1" MinWidth="120"> <!-- Notice we have used x:Name to identify the object that we want to operate upon.-->
<!--
<ComboBoxItem Content="X"/>
<ComboBoxItem Content="Y"/>
<ComboBoxItem Content="Z"/>
-->
</ComboBox>
</StackPanel>
</StackPanel>
<StackPanel DockPanel.Dock="Bottom" Background="Orange" Margin="2">
<StackPanel Orientation="Horizontal" x:Name="spBottomNav">
</StackPanel>
<TextBlock Height="30" Foreground="White">Left Docked StackPanel 2</TextBlock>
</StackPanel>
<StackPanel MinWidth="200" DockPanel.Dock="Left" Background="Teal" Margin="2" x:Name="StackPanelLeft">
<TextBlock Foreground="White">Bottom Docked StackPanel Left</TextBlock>
</StackPanel>
<StackPanel DockPanel.Dock="Right" Background="Yellow" MinWidth="150" Margin="2" x:Name="StackPanelRight"></StackPanel>
<Button Content="Button" Height="410" VerticalAlignment="Top" Width="75" x:Name="myButton" Click="myButton_Click"/>
</DockPanel>
</Window>
Next, we have the C# code:
private void myButton_Click(object sender, RoutedEventArgs e)
{
ComboBoxItem cboBoxItem = new ComboBoxItem(); // Create example instance of our desired type.
Type type1 = cboBoxItem.GetType();
object cboBoxItemInstance = Activator.CreateInstance(type1); // Construct an instance of that type.
for (int i = 0; i < 12; i++)
{
string newName = "stringExample" + i.ToString();
// Generate the objects from our list of strings.
ComboBoxItem item = this.CreateComboBoxItem((ComboBoxItem)cboBoxItemInstance, "nameExample_" + newName, newName);
cboBox1.Items.Add(item); // Add each newly constructed item to our NAMED combobox.
}
}
private ComboBoxItem CreateComboBoxItem(ComboBoxItem myCbo, string content, string name)
{
Type type1 = myCbo.GetType();
ComboBoxItem instance = (ComboBoxItem)Activator.CreateInstance(type1);
// Here, we're using reflection to get and set the properties of the type.
PropertyInfo Content = instance.GetType().GetProperty("Content", BindingFlags.Public | BindingFlags.Instance);
PropertyInfo Name = instance.GetType().GetProperty("Name", BindingFlags.Public | BindingFlags.Instance);
this.SetProperty<ComboBoxItem, String>(Content, instance, content);
this.SetProperty<ComboBoxItem, String>(Name, instance, name);
return instance;
//PropertyInfo prop = type.GetProperties(rb1);
}
Note: This is using reflection. If you'd like to learn more about the basics of reflection and why you might want to use it, this is a great introductory article:
If you'd like to learn more about how you might use reflection with WPF specifically, here are some resources:
And if you want to massively speed up the performance of reflection, it's best to use IL to do that, like this:
You can try this:
<a href="link.html">
<input type="button" value="Visit Page" />
</a>
This will create button inside a link and it works on any browser
Place it inside another div, use CSS to move the button to the middle:
<div style="width:100%;height:100%;position:absolute;vertical-align:middle;text-align:center;">
<button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%">
mybuttonname</button>
</div>?
Here is an example: JsFiddle
Just set layout_with
to a definate size, when the text fills the maximum width it will overflow to the next line causing a wrap effect.
<TextView
android:id="@+id/segmentText"
android:layout_marginTop="10dp"
android:layout_below="@+id/segmentHeader"
android:text="You have the option to record in one go or segments(if you swap options
you will loose your current recordings)"
android:layout_width="300dp"
android:layout_height="wrap_content"/>
push()
is for arrays, not objects, so use the right data structure.
var data = [];
// ...
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };
// ...
var tempData = [];
for ( var index=0; index<data.length; index++ ) {
if ( data[index].Status == "Valid" ) {
tempData.push( data );
}
}
data = tempData;
style = window.getComputedStyle(your_element);
then simply: style.height
For creating a new file
x1 = np.random.randn(100, 2)
df1 = pd.DataFrame(x1)
with pd.ExcelWriter('sample.xlsx') as writer:
df1.to_excel(writer, sheet_name='x1')
For appending to the file, use the argument mode='a'
in pd.ExcelWriter
.
x2 = np.random.randn(100, 2)
df2 = pd.DataFrame(x2)
with pd.ExcelWriter('sample.xlsx', engine='openpyxl', mode='a') as writer:
df2.to_excel(writer, sheet_name='x2')
Default is mode ='w'

`Notification notification = new Notification.Builder(this,STRING_ID)
.setSmallIcon(android.R.drawable.ic_menu_help)
.setContentTitle("Hello Notification")
.setContentText("It is Working")
.setContentIntent(pendingIntent)
.build();`
Channel id in the notification and in the notification should be same Whole code is like this.. `
@RequiresApi(api = Build.VERSION_CODES.O)
private void callNotification2() {
Intent intent = new Intent(getApplicationContext(),MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,11,

Try TinyXML or IrrXML...Both are lightweight XML parsers ( I'd suggest you to use TinyXML, anyway ).
From your shell run:
pip2 install unicodecsv
And (unlike the original question) presuming you're using Python's built in csv
module, turn
import csv
into
import unicodecsv as csv
in your code.
In SQL Server 2012 and later, there is the FORMAT()
function. You can pass it a 'P'
parameter for percentage. For example:
SELECT FORMAT((37.0/38.0),'P') as [Percentage] -- 97.37 %
To support percentage decimal precision, you can use P0
for no decimals (whole-numbers) or P3
for 3 decimals (97.368%).
SELECT FORMAT((37.0/38.0),'P0') as [WholeNumberPercentage] -- 97 %
SELECT FORMAT((37.0/38.0),'P3') as [ThreeDecimalsPercentage] -- 97.368 %
Just use the 'Rebuild Project' from the 'Build' menu from the top menu bar.
All of the (text-) files into one

This returns the quarter of the @date
, assuming @date
is a DATETIME
.
Here is my solution to this problem but with numbers and using the new 'Set' feature. Its not very performant but i definitely had a lot of fun writing this and it does support multiple maximum values.
const mode = (arr) => [...new Set(arr)]
.map((value) => [value, arr.filter((v) => v === value).length])
.sort((a,b) => a[1]-b[1])
.reverse()
.filter((value, i, a) => a.indexOf(value) === i)
.filter((v, i, a) => v[1] === a[0][1])
.map((v) => v[0])
mode([1,2,3,3]) // [3]
mode([1,1,1,1,2,2,2,2,3,3,3]) // [1,2]
By the way do not use this for production this is just an illustration of how you can solve it with ES6 and Array functions only.
Here is something that i have been trying.(Insertion sort- not the best way to sort but does the work)
def sort(list):
for index in range(1,len(list)):
value = list[index]
i = index-1
while i>=0:
if value < list[i]:
list[i+1] = list[i]
list[i] = value
i -= 1
else:
break
Serialize and unserialize are pretty common for that. You could also use JSON via json_encode and json_decode for a less PHP-specific format.
The Date
constructor that takes a single number is expecting the number of milliseconds since December 31st, 1969.
Date.getDate()
returns the day index for the current date object. In your example, the day is 30
. The final expression is 31
, therefore it's returning 31 milliseconds after December 31st, 1969.
A simple solution using your existing approach is to use Date.getTime()
instead. Then, add a days worth of milliseconds instead of 1
.
For example,
var dateString = 'Mon Jun 30 2014 00:00:00';
var startDate = new Date(dateString);
// seconds * minutes * hours * milliseconds = 1 day
var day = 60 * 60 * 24 * 1000;
var endDate = new Date(startDate.getTime() + day);
Please note that this solution doesn't handle edge cases related to daylight savings, leap years, etc. It is always a more cost effective approach to instead, use a mature open source library like moment.js to handle everything.
Add both http and https configuration:
export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=yourserver -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password"
export JAVA_OPTS="$JAVA_OPTS -Dhttps.proxyHost=yourserver -Dhttps.proxyPort=8080 -Dhttps.proxyUser=username -Dhttps.proxyPassword=password"
(https config is must, since many urls referred by the sbt libraries are https)
In fact, I even had an extra setting 'http.proxySet'
to 'true'
in both configuration entries.
<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>
Add Defer to the end of your Script tag, it worked for me (;
Everything needs to be loaded in the correct order (:
Your controller method should be like this:
@RequestMapping(value = " /<your mapping>/{id}", method=RequestMethod.GET)
public String listNotes(@PathVariable("id")int id,Model model) {
Person person = personService.getCurrentlyAuthenticatedUser();
int id = 2323; // Currently passing static values for testing
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("listNotes",this.notesService.listNotesBySectionId(id,person));
return "note";
}
Use the id
in your code, call the controller method from your JSP as:
/{your mapping}/{your id}
UPDATE:
Change your jsp code to:
<c:forEach items="${listNotes}" var="notices" varStatus="status">
<tr>
<td>${notices.noticesid}</td>
<td>${notices.notetext}</td>
<td>${notices.notetag}</td>
<td>${notices.notecolor}</td>
<td>${notices.sectionid}</td>
<td>${notices.canvasid}</td>
<td>${notices.canvasnName}</td>
<td>${notices.personid}</td>
<td><a href="<c:url value='/editnote/${listNotes[status.index].noticesid}' />" >Edit</a></td>
<td><a href="<c:url value='/removenote/${listNotes[status.index].noticesid}' />" >Delete</a></td>
</tr>
</c:forEach>
Another option is:
<Grid container justify = "center">
<Your centered component/>
</Grid>
Suggested way is StopIteration. Please see Fibonacci example from tutorialspoint
#!usr/bin/python3
import sys
def fibonacci(n): #generator function
a, b, counter = 0, 1, 0
while True:
if (counter > n):
return
yield a
a, b = b, a + b
counter += 1
f = fibonacci(5) #f is iterator object
while True:
try:
print (next(f), end=" ")
except StopIteration:
sys.exit()
In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.
This is normally more an issue with ToMany than ToOnes. For example,
Select e from Employee e
join fetch e.phones p
where p.areaCode = '613'
This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.
Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.
You could use find
to solve your problem
const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}
find(data, item)
// > true

else
echo "BRANCH '$BRANCH' DOES NOT MATCH BRANCH_REGEX '$BRANCH_REGEX'"

Use some delimeter,like this:
In your apache conf folder, open the httpd file and look for 8080 port. Change 8080 to any port you like. I believe you will find 8080 on two places. Restart your server to see changes.
Unlike the C#/.NET class library (and most other sensible languages), when you pass a String
in as the string-to-match argument to the string.replace
method, it doesn't do a string replace. It converts the string to a RegExp
and does a regex substitution. As Gumbo explains, a regex substitution requires the g
?lobal flag, which is not on by default, to replace all matches in one go.
If you want a real string-based replace — for example because the match-string is dynamic and might contain characters that have a special meaning in regexen — the JavaScript idiom for that is:
var id= 'c_'+date.split('/').join('');
use a trigges it will work:-
->CREATE TRIGGER trigger_name BEFORE INSERT ON table_name
FOR EACH ROW SET NEW.column_name3 = NEW.column_name1 + NEW.column_name2;
this will only work only when you will insert a row in table not when you will be updating your table for such a pupose create another trigger of different name and use UPDATE on the place of INSERT in the above syntax
This was the best solution I found that works reliably.
function round(value, decimals) {
return Number(Math.floor(parseFloat(value + 'e' + decimals)) + 'e-' + decimals);

Here are some ways:
1. if($("div").hasClass("mydivclass")){
//Your code
//It returns true if any div has 'mydivclass' name. It is a based on the class name
}
2. if($("#myid1").hasClass("mydivclass")){
//Your code
// It returns true if specific div(myid1) has this class "mydivclass" name.
// It is a based on the specific div id's.
}
3. if($("div[class='mydivclass']").length > 0){
//Your code
// It returns all the divs whose class name is "mydivclass"
// and it's length would be greater than one.
}
We can use any one of the abobe defined ways based on the requirement.
The --no-ff
option ensures that a fast forward merge will not happen, and that a new commit object will always be created. This can be desirable if you want git to maintain a history of feature branches.
In the above image, the left side is an example of the git history after using git merge --no-ff
and the right side is an example of using git merge
where an ff merge was possible.
EDIT: A previous version of this image indicated only a single parent for the merge commit. Merge commits have multiple parent commits which git uses to maintain a history of the "feature branch" and of the original branch. The multiple parent links are highlighted in green.

a.mean()
takes an axis
argument:
In [1]: import numpy as np
In [2]: a = np.array([[40, 10], [50, 11]])
In [3]: a.mean(axis=1) # to take the mean of each row
Out[3]: array([ 25. , 30.5])
In [4]: a.mean(axis=0) # to take the mean of each col
Out[4]: array([ 45. , 10.5])
Or, as a standalone function:
In [5]: np.mean(a, axis=1)
Out[5]: array([ 25. , 30.5])
The reason your slicing wasn't working is because this is the syntax for slicing:
In [6]: a[:,0].mean() # first column
Out[6]: 45.0
In [7]: a[:,1].mean() # second column
Out[7]: 10.5
The default values of null and blank are False.
Null: It is database-related. Defines if a given database column will accept null values or not.
Blank: It is validation-related. It will be used during forms validation, when calling form.is_valid().
That being said, it is perfectly fine to have a field with null=True and blank=False. Meaning on the database level the field can be NULL, but in the application level it is a required field.
Now, where most developers get it wrong: Defining null=True for string-based fields such as CharField and TextField. Avoid doing that. Otherwise, you will end up having two possible values for “no data”, that is: None and an empty string. Having two possible values for “no data” is redundant. The Django convention is to use the empty string, not NULL.
The question itself has already been addressed above. Just adding part of the default values.
As per http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionX.html
The default value of Xmx will depend on platform and amount of memory available in the system.

An efficient way to test/get values is TryGetValue
(thanx to Earwicker):
if (otherExample.TryGetValue("key", out value))
{
otherExample["key"] = value + 1;
}
With this method you can fast and exception-less get values (if present).

This is how you can CAUSE the error:
namespace MyNameSpace

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }

You might be needing a cleanup:
git gc --prune=now
or you might be needing a prune:
git remote prune public
prune
Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".
With --dry-run option, report what branches will be pruned, but do no actually prune them.
However, it appears these should have been cleaned up earlier with
git remote rm public
rm
Remove the remote named <name>. All remote tracking branches and configuration settings for the remote are removed.
So it might be you hand-edited your config file and this did not occur, or you have privilege problems.
Maybe run that again and see what happens.
If you take a look in the revision logs, you'll note I suggested more "correct" techniques, which for whatever reason didn't want to work on their repository.
I suspected the OP had done something that left their tree in an inconsistent state that caused it to behave a bit strangely, and git gc
was required to fix up the left behind cruft.
Usually git branch -rd origin/badbranch
is sufficient for nuking a local tracking branch , or git push origin :badbranch
for nuking a remote branch, and usually you will never need to call git gc
Use a semaphore with a count that is equal to the number of readers. Let each reader take one count of the semaphore in order to read, that way they can all read at the same time. Then let the writer take ALL the semaphore counts prior to writing. This causes the writer to wait for all reads to finish and then block out reads while writing.
As the statement executed is not actually DML (eg UPDATE
, INSERT
or EXECUTE
), but a piece of T-SQL which contains DML, I suspect it is not treated as an update-query.
Section 13.1.2.3 of the JDBC 4.1 specification states something (rather hard to interpret btw):
When the method
execute
returns true, the methodgetResultSet
is called to retrieve the ResultSet object. Whenexecute
returns false, the methodgetUpdateCount
returns an int. If this number is greater than or equal to zero, it indicates the update count returned by the statement. If it is -1, it indicates that there are no more results.
Given this information, I guess that executeUpdate()
internally does an execute()
, and then - as execute()
will return false
- it will return the value of getUpdateCount()
, which in this case - in accordance with the JDBC spec - will return -1
.
This is further corroborated by the fact 1) that the Javadoc for Statement.executeUpdate()
says:
Returns: either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing
And 2) that the Javadoc for Statement.getUpdateCount() specifies:
the current result as an update count; -1 if the current result is a ResultSet object or there are no more results
Just to clarify: given the Javadoc for executeUpdate()
the behavior is probably wrong, but it can be explained.
Also as I commented elsewhere, the -1 might just indicate: maybe something was changed, but we simply don't know, or we can't give an accurate number of changes (eg because in this example it is a piece of T-SQL that is executed).
JavaScript injection is not at attack on your web application. JavaScript injection simply adds JavaScript code for the browser to execute. The only way JavaScript could harm your web application is if you have a blog posting or some other area in which user input is stored. This could be a problem because an attacker could inject their code and leave it there for other users to execute. This attack is known as Cross-Site Scripting. The worst scenario would be Cross-Site Forgery, which allows attackers to inject a statement that will steal a user's cookie and therefore give the attacker their session ID.
You can do a Runtime.getRuntime.exec(command) to relaunch the jar including classpath with args.

.abc.xyz {
width: 200px !important;

}
If you wanted to modify this using jQuery
$(document).ready(function() {
$("div.abc.xyz").width("200px");

One other thing that you should note is that uuid.getnode()
can fake the MAC addr by returning a random 48-bit number which may not be what you are expecting. Also, there's no explicit indication that the MAC address has been faked, but you could detect it by calling getnode()
twice and seeing if the result varies. If the same value is returned by both calls, you have the MAC address, otherwise you are getting a faked address.
>>> print uuid.getnode.__doc__
Get the hardware address as a 48-bit positive integer.
The first time this runs, it may launch a separate program, which could
be quite slow. If all attempts to obtain the hardware address fail, we
choose a random 48-bit number with its eighth bit set to 1 as recommended
in RFC 4122.

Or you can just create your own MediaTypeFormatter
. I use this for text/html
. If you add text/plain
to it, it'll work for you too:
public class TextMediaTypeFormatter : MediaTypeFormatter
{
public TextMediaTypeFormatter()
{
SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
}
public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
{
return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
}
public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
{
using (var streamReader = new StreamReader(readStream))
{
return await streamReader.ReadToEndAsync();
}
}
public override bool CanReadType(Type type)
{
return type == typeof(string);
}
public override bool CanWriteType(Type type)
{
return false;
}
}
Finally you have to assign this to the HttpMethodContext.ResponseFormatter
property.
Obviously there is no "better" -- or more worth learning -- language at all. Which language you use is is just a matter of what you like AND what your server supports. You should not learn a language that wouldn't be supported by any server or is said to be dying in the near future. On the other hand it is obvious too that there will be even better languages in the future and that those will be more useful. So learn one that is fast, convenient and that you like and where learning it wouldn't be a too big effort because, as said, you're likely to change in less than 3 years.
I, personally would be considering an "open-source" (not proprietary) one, because the web is open to everyone and open-source is more likely to be supported by every-one. (Which means PHP in this case)

In real life you wish to simulate a signal with white noise. You should add to your signal random points that have Normal Gaussian distribution.

Generally, The DNS Domain of the URL MUST match the Certificate Subject of the certificate.
In former times this could be either by setting the domain as cn of the certificate or by having the domain set as a Subject Alternative Name.
Support for cn was deprecated for a long time (since 2000 in RFC 2818) and Chrome browser will not even look at the cn anymore so today you need to have the DNS Domain of the URL as a Subject Alternative Name.
RFC 6125 which forbids checking the cn if SAN for DNS Domain is present, but not if SAN for IP Address is present. RFC 6125 also repeats that cn is deprecated which was already said in RFC 2818. And the Certification Authority Browser Forum to be present which in combination with RFC 6125 essentially means that cn will never be checked for DNS Domain name.
I had the same problem.
Solution:
It looks like your MySql session has the safe-updates option set. This means that you can't update or delete records without specifying a key (ex. primary key
) in the where clause.
Try:
SET SQL_SAFE_UPDATES = 0;
Or you can modify your query to follow the rule (use primary key
in where clause
).

If you want to access redis
from the host (127.0.0.1), you have to use the ports
command.
redis:

A trap is called by code like programs and used e. g. to call OS routines (i. e. normally synchronous). An interrupt is called by events (many times hardware, like the network card having received data, or the CPU timer), and - as the name suggests - interrupts the normal control flow, as the CPU has to switch to the driver routine to handle the event.
I replaced the "localhost" with IP Address (Database server's public IP Address) in the jdbc Url then it worked.
jdbcUrl = "jdbc:oracle:thin:<user>@//localhost:1521/<Service Name>";
??
jdbcUrl = "jdbc:oracle:thin:<user>@//<Public IP Address>:1521/<Service Name>";
example how i made it , After i fill a Maximum length it will blur from my Field (and the Keyboard will disappear ) , if you have more than one field , you can just add the line that i add '//'
var MaxLength = 8;
$(document).ready(function () {
$('#MyTB').keyup(function () {
if ($(this).val().length >= MaxLength) {
$('#MyTB').blur();
// $('#MyTB2').focus();
}
}); });

Just set the height and width where you are adding that logo. I tried and its working fine
Sometimes you can just do 'Window -> Reset Window Layout', and that'll work :)
I solved that adding a Web facet.
The error you get if because you need to escape the quotes (like other answers said).
To avoid that, you can use an alternative syntax for you strings declarations, called "Heredoc"
With this syntax, you can declare a long string, even containing single-quotes and/or double-quotes, whithout having to escape thoses ; it will make your Javascript code easier to write, modify, and understand -- which is always a good thing.
As an example, your code could become :
$str = <<<MY_MARKER
<script type="text/javascript">
document.write("Hello World!");
</script>
MY_MARKER;
echo $str;
Note that with Heredoc syntax (as with string delimited by double-quotes), variables are interpolated.

If you are using Maven for your project, Maven command line parameters can be passed like this for example -Dsonar.coverage.exclusions=**/config/*,**/model/*
I was having problem with excluding single class explicitly. Below my observations:
**/*GlobalExceptionhandler.java - not working for some reason, I was expecting such syntax should work
com/some/package/name/GlobalExceptionhandler.java - not working
src/main/java/com/some/package/name/GlobalExceptionhandler.java - good, class excluded explicitly without using wildcards
Call this in the project:
svn diff -r REVNO:HEAD --summarize
REVNO
is the start revision number and HEAD
is the end revision number. If HEAD is equal to the last revision number, it can skip it.
The command returns a list with all files that are changed/added/deleted in this revision period.
The command can be called with the URL revision parameter to check changes like this:
svn diff -r REVNO:HEAD --summarize SVN_URL
A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.
To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.
There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.
A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.
There is an option

print
and echo
are more or less the same; they are both language constructs that display strings. The differences are subtle: print
has a return value of 1 so it can be used in expressions whereas echo
has a void
return type; echo
can take multiple parameters, although such usage is rare; echo
is slightly faster than print
. (Personally, I always use echo
, never print
.)
var_dump
prints out a detailed dump of a variable, including its type and the type of any sub-items (if it's an array or an object). print_r
prints a variable in a more human-readable form: strings are not quoted, type information is omitted, array sizes aren't given, etc.
var_dump
is usually more useful than print_r
when debugging, in my experience. It's particularly useful when you don't know exactly what values/types you have in your variables. Consider this test program:
$values = array(0, 0.0, false, '');
var_dump($values);
print_r ($values);
With print_r
you can't tell the difference between 0
and 0.0
, or false
and ''
:
array(4) {
[0]=>
int(0)
[1]=>
float(0)
[2]=>
bool(false)
[3]=>
string(0) ""
}
Array
(
[0] => 0
[1] => 0
[2] =>
[3] =>
)
Similar to above, using filter

A better way to do a break line is using span with CSS style parameter white-space: nowrap;
span.nobreak {
white-space: nowrap;
}
or
span.nobreak {

white-space: nowrap;
}
Example directly in your HTML
<span style='overflow:hidden; white-space: nowrap;'> YOUR EXTENSIVE TEXT THAT YOU CAN´T BREAK LINE ....</span>
in my case, I Edit my gradle.properties

and add this lines in ur build.gradle

dexOptions {

preDexLibraries = false
javaMaxHeapSize "4g" // 2g should be also OK
}
hope this help some one :)
A jar file is just a zip file with a structured manifest. You can open the jar file with the usual java zip tools and scan the file contents that way, inflate streams, etc. Then use that in a getResourceAsStream call, and it should be all hunky dory.
EDIT / after clarification
It took me a minute to remember all the bits and pieces and I'm sure there are cleaner ways to do it, but I wanted to see that I wasn't crazy. In my project image.jpg is a file in some part of the main jar file. I get the class loader of the main class (SomeClass is the entry point) and use it to discover the image.jpg resource. Then some stream magic to get it into this ImageInputStream thing and everything is fine.
InputStream inputStream = SomeClass.class.getClassLoader().getResourceAsStream("image.jpg");
JPEGImageReaderSpi imageReaderSpi = new JPEGImageReaderSpi();
ImageReader ir = imageReaderSpi.createReaderInstance();
ImageInputStream iis = new MemoryCacheImageInputStream(inputStream);
ir.setInput(iis);
....
ir.read(0); //will hand us a buffered image

In my case it was SQLCA.DBParm
parameter.
I used
SQLCA.DBParm = "Databse = "sle_database.text""
but it must be
SQLCA.DBParm = "Database='" +sle_database.text+ "'"
Explaination :
You are going to combine three strings :
1. Database=' - "Database='"
2. (name of the database) - +sle_database.text+
3. ' - "'" (means " ' " without space)

Check that you are extending CI_Controller
class in your controller and in the view you have to echo base_url($path)
function, otherwise it will not work.
In my experience, just pick a relatively high number (between 1024-65535) that you think is unlikely to be used by anything else. For example, port # 8080 and # 5555 are ones that I routinely use. Just pick a port number like this as opposed to just making the code randomly select it and then having to find the port number later is much easier for me.
For example, in my current ChatBot project:
port = 8080
I did not know about Environment.Newline, but I guess this is a very good solution.
My try would have been:
string str = "Test Me\r\nTest Me\nTest Me";
var splitted = str.Split('\n').Select(s => s.Trim()).ToArray();
The additional .Trim removes any \r or \n that might be still present (e. g. when on windows but splitting a string with os x newline characters). Probably not the fastest method though.
EDIT:
As the comments correctly pointed out, this also removes any whitespace at the start of the line or before the new line feed. If you need to preserve that whitespace, use one of the other options.
Perhaps this will help? The definition of the primary key column should be exactly the same as the foreign key column.
int w =0 , l =0, d=0, i=0;
Scanner sc = new Scanner(System.in);
// try tentimes
while (i<10) {
System.out.println("scissor(1) ,Rock(2),Paper(3) ");
int n = sc.nextInt();
int m =(int)(Math.random()*3+1);
if(n==m){
System.out.println("Com:"+m +"so>>> " + "draw");
d++;
}else if ((n-1)%3==(m%3)){
w++;
System.out.println("Com:"+m +"so>>> " +"win");
}
else if(n >=4 )
{
System.out.println("pleas enter correct number)");
}
else {
System.out.println("Com:"+m +"so>>> " +"lose");
l++;
}
i++;
Another difference not pointed out is that giving the struct a name (i.e. struct myStruct) also enables you to provide forward declarations of the struct. So in some other file, you could write:
struct myStruct;
void doit(struct myStruct *ptr);
without having to have access to the definition. What I recommend is you combine your two examples:
typedef struct myStruct{
int one;
int two;
} myStruct;
This gives you the convenience of the more concise typedef name but still allows you to use the full struct name if you need.
use absolute path where the image actually exists (e.g) '/home/artitra/pictures/filename.jpg'
or create static folder inside your project directory like this
| templates
- static/
- images/
- yourimagename.jpg
then do this
app = Flask(__name__, static_url_path='/static')
then you can access your image like this in index.html
src ="/static/images/yourimage.jpg"
in img tag
Below is example you can use:
create temp table test2 (
id1 numeric,
id2 numeric,
id3 numeric,
id4 numeric,
id5 numeric,
id6 numeric,
id7 numeric,
id8 numeric,
id9 numeric,
id10 numeric)
with (oids = false);
do
$do$
declare
i int;
begin
for i in 1..100000
loop
insert into test2 values (random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random());
end loop;
end;
$do$;
You could subscribe to the TextChanged
event on the TextBox
and if the text is empty set the Button
to disabled. Or you could bind the Button.IsEnabled
property to the TextBox.Text
property and use a converter that returns true if there is any text and false otherwise.
Firstly — I don't think column1 is not NULL or column1 <> ''
makes very much sense. Maybe you meant to write column1 is not NULL and column1 <> ''
(AND
instead of OR
)?
Secondly — because of Hive's "schema on read" approach to table definitions, invalid values will be converted to NULL
when you read from them. So, for example, if table1.column1
is of type STRING
and table2.column1
is of type INT
, then I don't think that table1.column1 IS NOT NULL
is enough to guarantee that table2.column1 IS NOT NULL
. (I'm not sure about this, though.)
In case you want to improve the commit message with header and body after you created the commit, you can reword it. This approach is more useful because you know what the code does only after you wrote it.
git rebase -i origin/master
Then, your commits will appear:
pick e152ce2 Update framework
pick ffcf91e Some magic
pick fa672e1 Update comments
Select the commit you want to reword and save.
pick e152ce2 Update framework
reword ffcf91e Some magic
pick fa672e1 Update comments
Now, you have the opportunity to add header and body, where the first line will be the header.

When one of my VB.NET classes has all shared members I either convert it to a Module with a matching (or otherwise appropriate) namespace or I make the class not inheritable and not constructable:

'Private constructor means the class cannot be instantiated.
End Sub
End Class

Update
The link above takes to a question that was closed and then deleted. Here are the original suggestions that were on the most voted answer:
Assuming you can get a Stream, FileStream or MemoryStream for instance, you can do this:
Stream file = [Some Code that Gets you a stream];
var filename = [The name of the file you want to user to download/see];
if (file != null && file.CanRead)
{
context.Response.AddHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
context.Response.ContentType = "application/octet-stream";
context.Response.ClearContent();
file.CopyTo(context.Response.OutputStream);
}
Thats a copy and paste from some of my working code, so the content type might not be what youre looking for, but writing the stream to the response is the trick on the last line.
There are several ways to do it. The subplots
method creates the figure along with the subplots that are then stored in the ax
array. For example:
import matplotlib.pyplot as plt
x = range(10)
y = range(10)
fig, ax = plt.subplots(nrows=2, ncols=2)
for row in ax:
for col in row:
col.plot(x, y)
plt.show()
However, something like this will also work, it's not so "clean" though since you are creating a figure with subplots and then add on top of them:
fig = plt.figure()
plt.subplot(2, 2, 1)
plt.plot(x, y)
plt.subplot(2, 2, 2)
plt.plot(x, y)
plt.subplot(2, 2, 3)
plt.plot(x, y)
plt.subplot(2, 2, 4)
plt.plot(x, y)
plt.show()
Using regex is a solution, but it is too complicated for that case.
You can simply split text into list of words. Use split(separator, num) method for that. It returns a list of all the words in the string, using separator as the separator. If separator is unspecified it splits on all whitespace (optionally you can limit the number of splits to num).
list_of_words = mystring.split()
if word in list_of_words:
print 'success'
This will not work for string with commas etc. For example:
mystring = "One,two and three"
# will split into ["One,two", "and", "three"]
If you also want to split on all commas etc. use separator argument like this:
# whitespace_chars = " \t\n\r\f" - space, tab, newline, return, formfeed
list_of_words = mystring.split( \t\n\r\f,.;!?'\"()")
if word in list_of_words:
print 'success'
BH's answer of installing Java 6u45 was very close... still got the popup on reboot...BUT after uninstalling Java 6u45, rebooted, no warning! Thank you BH! Then installed the latest version, 8u151-i586, rebooted no warning.
I added lines in PATH as above, didn't do anything.
My system: Windows 7, 64 bit. Warning was for No JVM, 32 bit Java not found. Yes, I could have installed the 64 bit version, but 32bit is more compatible with all programs.
As Chris suggests, you can do it like this:
public string GetXMLAsString(XmlDocument myxml)
{
return myxml.OuterXml;
}
Or like this:
public string GetXMLAsString(XmlDocument myxml)
{
StringWriter sw = new StringWriter();
XmlTextWriter tx = new XmlTextWriter(sw);
myxml.WriteTo(tx);
string str = sw.ToString();//
return str;
}
and if you really want to create a new XmlDocument
then do this
XmlDocument newxmlDoc= myxml
I tried Gaby's answer (+1) above but it only partially solved my problem. Instead I used the following CSS, where content-box was changed to border-box:
