As was written above, if the language you use has a JSON-library coming with it, use it to try decoding the string and catch the exception/error if it fails! If the language does not (just had such a case with FreeMarker) the following regex could at least provide some very basic validation (it's written for PHP/PCRE to be testable/usable for more users). It's not as foolproof as the accepted solution, but also not that scary =):
~^\{\s*\".*\}$|^\[\n?\{\s*\".*\}\n?\]$~s
short explanation:
// we have two possibilities in case the string is JSON
// 1. the string passed is "just" a JSON object, e.g. {"item": [], "anotheritem": "content"}
// this can be matched by the following regex which makes sure there is at least a {" at the
// beginning of the string and a } at the end of the string, whatever is inbetween is not checked!
^\{\s*\".*\}$
// OR (character "|" in the regex pattern)
// 2. the string passed is a JSON array, e.g. [{"item": "value"}, {"item": "value"}]
// which would be matched by the second part of the pattern above
^\[\n?\{\s*\".*\}\n?\]$
// the s modifier is used to make "." also match newline characters (can happen in prettyfied JSON)
if I missed something that would break this unintentionally, I'm grateful for comments!
For sure: qsort()
is an implementation of a sort (not necessarily quicksort as its name might suggest).
Try man 3 qsort or have a read at http://linux.die.net/man/3/qsort
I wanted to share another solution working with the ui router 1.0.0.X
As you may know, stateChangeStart and stateChangeSuccess are now deprecated. https://github.com/angular-ui/ui-router/issues/2655
Instead you should use $transitions http://angular-ui.github.io/ui-router/1.0.0-alpha.1/interfaces/transition.ihookregistry.html
This is how I achieved it:
First I have and AuthService with some useful functions
angular.module('myApp')
.factory('AuthService',
['$http', '$cookies', '$rootScope',
function ($http, $cookies, $rootScope) {
var service = {};
// Authenticates throug a rest service
service.authenticate = function (username, password, callback) {
$http.post('api/login', {username: username, password: password})
.success(function (response) {
callback(response);
});
};
// Creates a cookie and set the Authorization header
service.setCredentials = function (response) {
$rootScope.globals = response.token;
$http.defaults.headers.common['Authorization'] = 'Bearer ' + response.token;
$cookies.put('globals', $rootScope.globals);
};
// Checks if it's authenticated
service.isAuthenticated = function() {
return !($cookies.get('globals') === undefined);
};
// Clear credentials when logout
service.clearCredentials = function () {
$rootScope.globals = undefined;
$cookies.remove('globals');
$http.defaults.headers.common.Authorization = 'Bearer ';
};
return service;
}]);
Then I have this configuration:
angular.module('myApp', [
'ui.router',
'ngCookies'
])
.config(['$stateProvider', '$urlRouterProvider',
function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/resumen');
$stateProvider
.state("dashboard", {
url: "/dashboard",
templateUrl: "partials/dashboard.html",
controller: "dashCtrl",
data: {
authRequired: true
}
})
.state("login", {
url: "/login",
templateUrl: "partials/login.html",
controller: "loginController"
})
}])
.run(['$rootScope', '$transitions', '$state', '$cookies', '$http', 'AuthService',
function ($rootScope, $transitions, $state, $cookies, $http, AuthService) {
// keep user logged in after page refresh
$rootScope.globals = $cookies.get('globals') || {};
$http.defaults.headers.common['Authorization'] = 'Bearer ' + $rootScope.globals;
$transitions.onStart({
to: function (state) {
return state.data != null && state.data.authRequired === true;
}
}, function () {
if (!AuthService.isAuthenticated()) {
return $state.target("login");
}
});
}]);
You can see that I use
data: {
authRequired: true
}
to mark the state only accessible if is authenticated.
then, on the .run I use the transitions to check the autheticated state
$transitions.onStart({
to: function (state) {
return state.data != null && state.data.authRequired === true;
}
}, function () {
if (!AuthService.isAuthenticated()) {
return $state.target("login");
}
});
I build this example using some code found on the $transitions documentation. I'm pretty new with the ui router but it works.
Hope it can helps anyone.
The way I solved this, which is another option (if you have jQuery available), was to Define the fields in an old-school object and then extend the class with that object. I also didn't want to pepper the constructor with assignments, this appeared to be a neat solution.
function MyClassFields(){
this.createdAt = new Date();
}
MyClassFields.prototype = {
id : '',
type : '',
title : '',
createdAt : null,
};
class MyClass {
constructor() {
$.extend(this,new MyClassFields());
}
};
-- Update Following Bergi's comment.
No JQuery Version:
class SavedSearch {
constructor() {
Object.assign(this,{
id : '',
type : '',
title : '',
createdAt: new Date(),
});
}
}
You still do end up with 'fat' constructor, but at least its all in one class and assigned in one hit.
EDIT #2: I've now gone full circle and am now assigning values in the constructor, e.g.
class SavedSearch {
constructor() {
this.id = '';
this.type = '';
this.title = '';
this.createdAt = new Date();
}
}
Why? Simple really, using the above plus some JSdoc comments, PHPStorm was able to perform code completion on the properties. Assigning all the vars in one hit was nice, but the inability to code complete the properties, imo, isn't worth the (almost certainly minuscule) performance benefit.
In a commercial scenario, a serious contestant for sure is yFiles for HTML:
It offers:
Here is a sample rendering that shows most of the requested features:
Full disclosure: I work for yWorks, but on Stackoverflow I do not represent my employer.
this is a good method:
git tag -l | xargs git tag -d && git fetch -t

You can simply add this CSS to your header
<link href='http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css' rel='stylesheet' type='text/css'>
next add this code in place where you want to display a glyph symbol.
<div class="fa fa-search"></div> <!-- smaller -->
<div class="fa fa-search fa-2x"></div> <!-- bigger -->
Have fun.
foo="Hello"
foo="${foo} World"
echo "${foo}"
> Hello World
In general to concatenate two variables you can just write them one after another:
a='Hello'
b='World'
c="${a} ${b}"
echo "${c}"
> Hello World
Strings are just as iterable as arrays, so just convert it to string:
str(12345)
Use [] instead of () as below example.
SqlDataAdapter adapter = new SqlDataAdapter(sql, ConfigurationManager.ConnectionStrings["FADB_ConnectionString"].ConnectionString);
DataTable data = new DataTable();
DataSet ds = new DataSet();
There is another solution if you want to develop in C/C++. http://www.DragonFireSDK.com will allow you to build iPhone applications in Visual Studio on Windows. It's worth a look-see for sure.
Another modelling tool for Java is (my) website GitUML. Generate UML diagrams from Java or Python code stored in GitHub repositories.
One key idea with GitUML is to address one of the problems with "documentation": that diagrams are always out of date. With GitUML, diagrams automatically update when you push code using git.
Browse through community UML diagrams, there are some Java design patterns there. Surf through popular GitHub repositories and visualise the architectures and patterns in them.
Create diagrams using point and click. There is no drag drop editor, just click on the classes in the repository tree that you want to visualise:
The underlying technology is PlantUML based, which means you can refine your diagrams with additional PlantUML markup.
Below code for best examples for nested loops, while using two for loops please remember the output of the first loop is input for the second loop. Loop termination also important while using the nested loops
for x in range(1, 10, 1):
for y in range(1,x):
print y,
print
OutPut :
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8
C++11 has some portable timer stuff. Check out sleep_for.
grep -i -w 'string1\|string2' filename
This works for exact word match and matching case insensitive words ,for that -i is used
Assuming you're using Spring Boot, another option is to put the following in your application.properties
:
logging.level.org.springframework.security=DEBUG
This is the same for most other Spring modules as well.
If you're not using Spring Boot, try setting the property in your logging configuration, e.g. logback.
Here is the application.yml version as well:
logging:
level:
org:
springframework:
security: DEBUG
There's no fast way to retrieve attributes. But code ought to look like this (credit to Aaronaught):
var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var hasIsIdentity = Attribute.IsDefined(pi, typeof(IsIdentity));
If you need to retrieve attribute properties then
var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var attr = (IsIdentity[])pi.GetCustomAttributes(typeof(IsIdentity), false);
if (attr.Length > 0) {
// Use attr[0], you'll need foreach on attr if MultiUse is true
}
In my case $(document).ready(function() was missing. Try this.
$(document).ready(function(){
("#table tr").click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
var value=$(this).find('td:first').html();
alert(value);
});
$('.ok').on('click', function(e){
alert($("#table tr.selected td:first").html());
});
});
here's how you can do it with a cool shell trick:
mysql -uroot -p -hslavedb.mydomain.com mydb_production <<< 'select * from users'
'<<<' instructs the shell to take whatever follows it as stdin, similar to piping from echo.
use the -t flag to enable table-format output
something like this is close: (untested code)
byte[] data; // data goes here.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = userNetworkCredentials;
request.Method = "PUT";
request.ContentType = "application/octet-stream";
request.ContentLength = data.Length;
Stream stream = request.GetRequestStream();
stream.Write(data,0,data.Length);
stream.Close();
response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
temp = reader.ReadToEnd();
reader.Close();
I would say, in your layout file give a
<div id="background"></div>
and then in your css do
#background {
position: fixed;
top: 50%;
left: 50%;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
-webkit-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);
background: image-url('background.png') no-repeat;
background-size: cover;
}
And be sure to have the background image in your app/assets/images and also change the
background: image-url('background.png') no-repeat;
'background.png' to your own background pic.
First, Remember that this logfile can grow very large on a busy server.
For mysql < 5.1.29:
To enable the query log, put this in /etc/my.cnf
in the [mysqld]
section
log = /path/to/query.log #works for mysql < 5.1.29
Also, to enable it from MySQL console
SET general_log = 1;
See http://dev.mysql.com/doc/refman/5.1/en/query-log.html
For mysql 5.1.29+
With mysql 5.1.29+ , the log
option is deprecated. To specify the logfile and enable logging, use this in my.cnf in the [mysqld]
section:
general_log_file = /path/to/query.log
general_log = 1
Alternately, to turn on logging from MySQL console (must also specify log file location somehow, or find the default location):
SET global general_log = 1;
Also note that there are additional options to log only slow queries, or those which do not use indexes.
I was facing the same issue and fixed it with this command. It works for me, please update it as per your account. This is for Ubuntu machine where AWS-CLI needs to be installed with Docker
algorithm_name='multi-model-xgboost'
account=$(aws sts get-caller-identity --query Account --output text)
# Get the region defined in the current configuration
region=$(aws configure get region)
aws ecr get-login-password --region ${region} | docker login --username AWS --password-stdin ${account}.dkr.ecr.${region}.amazonaws.com/${algorithm_name}
Your problem is often due to looking in the wrong place for the image, or if your classes and images are in a jar file, then looking for files where files don't exist. I suggest that you use resources to get rid of the second problem.
e.g.,
// the path must be relative to your *class* files
String imagePath = "res/Image.png";
InputStream imgStream = Game.class.getResourceAsStream(imagePath );
BufferedImage myImg = ImageIO.read(imgStream);
// ImageIcon icon = new ImageIcon(myImg);
// use icon here
game.frame.setIconImage(myImg);
$str = preg_replace('/\?\//', '?', $str);
Edit: See CMS' answer. It's late, I should know better.
This seems unnecessary, but VBA is a strange place. If you declare an array variable, then set it using Array()
then pass the variable into your function, VBA will be happy.
Sub test()
Dim fString As String
Dim arr() As Variant
arr = Array("foo", "bar")
fString = processArr(arr)
End Sub
Also your function processArr()
could be written as:
Function processArr(arr() As Variant) As String
processArr = Replace(Join(arr()), " ", "")
End Function
If you are into the whole brevity thing.
In regards to deleting the symbolic links, I found this to be useful.

To facilitate svg editing you can use an intermediate function:
function getNode(n, v) {
n = document.createElementNS("http://www.w3.org/2000/svg", n);
for (var p in v)
n.setAttributeNS(null, p, v[p]);
return n
}
Now you can write:
svg.appendChild( getNode('rect', { width:200, height:20, fill:'#ff0000' }) );
Example (with an improved getNode function allowing camelcase for property with dash, eg strokeWidth > stroke-width):
function getNode(n, v) {_x000D_
n = document.createElementNS("http://www.w3.org/2000/svg", n);_x000D_
for (var p in v)_x000D_
n.setAttributeNS(null, p.replace(/[A-Z]/g, function(m, p, o, s) { return "-" + m.toLowerCase(); }), v[p]);_x000D_
return n_x000D_
}_x000D_
_x000D_
var svg = getNode("svg");_x000D_
document.body.appendChild(svg);_x000D_
_x000D_
var r = getNode('rect', { x: 10, y: 10, width: 100, height: 20, fill:'#ff00ff' });_x000D_
svg.appendChild(r);_x000D_
_x000D_
var r = getNode('rect', { x: 20, y: 40, width: 100, height: 40, rx: 8, ry: 8, fill: 'pink', stroke:'purple', strokeWidth:7 });_x000D_
svg.appendChild(r);
_x000D_
Add an item and set its "Selected" property to true, you will probably want to set "appenddatabounditems" property to true also so your initial value isn't deleted when databound.
If you are talking about setting an initial value that is in your databound items then hook into your ondatabound event and set which index you want to selected=true you will want to wrap it in "if not page.isPostBack then ...." though
Protected Sub DepartmentDropDownList_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DepartmentDropDownList.DataBound
If Not Page.IsPostBack Then
DepartmentDropDownList.SelectedValue = "somevalue"
End If
End Sub
$eval
and $parse
don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.
Q: What exactly is $eval doing? Why does it need its own mini parsing language?
From the docs:
Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.
It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).
Q: Why isn't plain old javascript "eval" being used?
Because it's not actually evaluating JavaScript. As the docs say:
If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.
The docs linked to above have a lot more information.
To link to a UNC path from an HTML document, use file:///// (yes, that's five slashes).
file://///server/path/to/file.txt
Note that this is most useful in IE and Outlook/Word. It won't work in Chrome or Firefox, intentionally - the link will fail silently. Some words from the Mozilla team:
For security purposes, Mozilla applications block links to local files (and directories) from remote files.
And less directly, from Google:
Firefox and Chrome doesn't open "file://" links from pages that originated from outside the local machine. This is a design decision made by those browsers to improve security.
The Mozilla article includes a set of client settings you can use to override this behavior in Firefox, and there are extensions for both browsers to override this restriction.
It is safer and more flexible to load the assembly into its own AppDomain
first.
So instead of the answer given previously:
var asm = Assembly.LoadFile(@"C:\myDll.dll");
var type = asm.GetType("TestRunner");
var runnable = Activator.CreateInstance(type) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();
I would suggest the following (adapted from this answer to a related question):
var domain = AppDomain.CreateDomain("NewDomainName");
var t = typeof(TypeIWantToLoad);
var runnable = domain.CreateInstanceFromAndUnwrap(@"C:\myDll.dll", t.Name) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();
Now you can unload the assembly and have different security settings.
If you want even more flexibility and power for dynamic loading and unloading of assemblies, you should look at the Managed Add-ins Framework (i.e. the System.AddIn
namespace). For more information, see this article on Add-ins and Extensibility on MSDN.
for(File f : files) {
f.delete();

I really struggled with getting the results of jQuery ajax into my variables at the "document.ready" stage of events.
jQuery's ajax would load into my variables when a user triggered an "onchange" event of a select box after the page had already loaded, but the data would not feed the variables when the page first loaded.
I tried many, many, many different methods, but in the end, it was Charles Guilbert's method that worked best for me.
Hats off to Charles Guilbert! Using his answer, I am able to get data into my variables, even when my page first loads.
Here's an example of the working script:
jQuery.extend
(
{
getValues: function(url)
{
var result = null;
$.ajax(
{
url: url,
type: 'get',
dataType: 'html',
async: false,
cache: false,
success: function(data)
{
result = data;
}
}
);
return result;
}
}
);
// Option List 1, when "Cats" is selected elsewhere
optList1_Cats += $.getValues("/MyData.aspx?iListNum=1&sVal=cats");
// Option List 1, when "Dogs" is selected elsewhere
optList1_Dogs += $.getValues("/MyData.aspx?iListNum=1&sVal=dogs");
// Option List 2, when "Cats" is selected elsewhere
optList2_Cats += $.getValues("/MyData.aspx?iListNum=2&sVal=cats");
// Option List 2, when "Dogs" is selected elsewhere
optList2_Dogs += $.getValues("/MyData.aspx?iListNum=2&sVal=dogs");

For the replacement portion, Python uses \1
the way sed and vi do, not $1
the way Perl, Java, and Javascript (amongst others) do. Furthermore, because \1
interpolates in regular strings as the character U+0001, you need to use a raw string or \escape it.

One potential solution
Thanks to Alan Haggai Alavi's solution I came up with the following potential workflow:
Step 1:
git fetch origin
Step 2:
git checkout -b localTempOfOriginMaster origin/master
git difftool HEAD~3 HEAD~2
git difftool HEAD~2 HEAD~1
git difftool HEAD~1 HEAD~0
Step 3:
git checkout master
git branch -D localTempOfOriginMaster
git merge origin/master
Also you can use f-string formatting to write integer to file
For appending use following code, for writing once replace 'a' with 'w'.
for i in s_list:
with open('path_to_file','a') as file:
file.write(f'{i}\n')
file.close()
Do it simply by adding a class to the body:
.stop-scrolling {
height: 100%;
overflow: hidden;
}
Add the class then remove when you want to re-enable scrolling, tested in IE, FF, Safari and Chrome.
$('body').addClass('stop-scrolling')
For mobile devices, you'll need to handle the touchmove
event:
$('body').bind('touchmove', function(e){e.preventDefault()})
And unbind to re-enable scrolling. Tested in iOS6 and Android 2.3.3
$('body').unbind('touchmove')

Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

First of all you need to build and run the App on your simulator. Then you open the Activity Monitor. Double click the name of your App to find its content.
In the next screen open the Open Files and Ports tab and find the line with MyAppName.app/MyAppName.
Copy the link but make sure to stop at the MyAppName.app. Do not copy the path following it.
Control click onto the finder icon and select Go to folder.
Paste the path and click enter. You will see your MyAppName.app file. Copy it to the Desktop and zip it. Move it to your desired 2nd computer and unzip the file. Build a random project to have a simulator open.
Lastly: Literally drag and drop the App from your Desktop into your Simulator. You will see the install and the App opens and does not crash.

The git.exe from Github for windows is located in a path like C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\bin\git.exe
1 You have to replace <username>
and <numbersandletters>
to the actual situation on your system.
In Android Studio you can specify the path to the Git executable at File->Settings...->Version Control->Git->Path to Git executable
. Here you have to include the actual executable name. As an example, in my case the actual path is: C:\Users\dennis\AppData\Local\GitHub\PortableGit_69703d1db91577f4c666e767a6ca5ec50a48d243\bin\git.exe
Edit: Last git update has put the git.exe file in cmd\ folder instead of bin\ . so now the actual path will be as suggested in the comment below by al3xAndr3w.
C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\cmd\git.exe
One way to solve this error is to put the ForeignKey

$current_uri = request()->segments();
To get segment posts
from http://example.com/users/posts/latest/
NOTE: Segments are an array that starts at index 0. The first element of array starts after the TLD part of the url. So in the above url, segment(0) will be users

.
//get segment 0
$segment_users = request()->segment(0); //returns 'users'
//get segment 1
$segment_posts = request()->segment(1); //returns 'posts'
You may have noted that the segment method only works with the current URL ( url()->current()
). So I designed a method to work with previous URL too by cloning the segment()
method:
public function index()
{
$prev_uri_segments = $this->prev_segments(url()->previous());
}
/**
* Get all of the segments for the previous uri.
*
* @return array
*/
public function prev_segments($uri)
{
$segments = explode('/', str_replace(''.url('').'', '', $uri));
return array_values(array_filter($segments, function ($value) {
return $value !== '';
}));
}
Suppose df is a pandas DataFrame then to get number of non-null values and data types of all column at once use:
df.info()

This console app will list all the values and their data from a registry key for most of the potential registry values. There's some weird ones not often used. If you need to support all of them, expand from this example while referencing this Registry Value Type documentation.

Use the following script to find and kill all the opened connections to the database before restoring database.
declare @sql as varchar(20), @spid as int
select @spid = min(spid) from master..sysprocesses where dbid = db_id('<database_name>')
and spid != @@spid
while (@spid is not null)
begin
print 'Killing process ' + cast(@spid as varchar) + ' ...'
set @sql = 'kill ' + cast(@spid as varchar)
exec (@sql)
select
@spid = min(spid)
from
master..sysprocesses
where
dbid = db_id('<database_name>')
and spid != @@spid
end
print 'Process completed...'
Hope this will help...
Other SQL implementations have similar restrictions. The reason is that adding a column requires adding values for that column (logically, even if not physically), which default to NULL
. If you don't allow NULL
, and don't have a default
, what is the value going to be?
Since SQL Server supports ADD CONSTRAINT
, I'd recommend Pavel's approach of creating a nullable column, and then adding a NOT NULL
constraint after you've filled it with non-NULL
values.
jQuery normalises event.which
depending on whether event.which
, event.keyCode
or event.charCode
is supported by the browser:
// Add which for key events
if ( event.which == null && (event.charCode != null || event.keyCode != null) ) {
event.which = event.charCode != null ? event.charCode : event.keyCode;
}
An added benefit of .which
is that jQuery does it for mouse clicks too:
// Add which for click: 1 === left; 2 === middle; 3 === right
// Note: button is not normalized, so don't use it
if ( !event.which && event.button !== undefined ) {
event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) ));
}
The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.
The normal way to get there from scratch is:
$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
name:string \
description:text \
price:decimal \
seller_id:integer \
email:string img_url:string
I use the ArrayDebugView add-in for Visual Studio (http://arraydebugview.sourceforge.net/).
It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.
It has a few quirks (tab order, modal dialog, no close button) but the ability to plot the contents of an array in a graph more than make up for it.
Edit July 2014: I have finally built a new Visual Studio extension to replace ArrayebugView's functionality. It is available on the VIsual Studio Gallery, search for ArrayPlotter or go to http://visualstudiogallery.msdn.microsoft.com/2fde2c3c-5b83-4d2a-a71e-5fdd83ce6b96?SRC=Home

I am a beginner in iPhone apps and I still have an issue although I followed the above advices. It looks like POST variables are not received by my server - not sure if it comes from php or objective-c code ...
the objective-c part (coded following Chris' protocol methodo)
// Create the request.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://example.php"]];
// Specify that it will be a POST request
request.HTTPMethod = @"POST";
// This is how we set header fields
[request setValue:@"application/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
// Convert your data and set your request's HTTPBody property
NSString *stringData = [NSString stringWithFormat:@"user_name=%@&password=%@", self.userNameField.text , self.passwordTextField.text];
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPBody = requestBodyData;
// Create url connection and fire request
//NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSData *response = [NSURLConnection sendSynchronousRequest:request
returningResponse:nil error:nil];
NSLog(@"Response: %@",[[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]);
Below the php part :
if (isset($_POST['user_name'],$_POST['password']))
{
// Create connection
$con2=mysqli_connect($servername, $username, $password, $dbname);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
else
{
// retrieve POST vars
$username = $_POST['user_name'];
$password = $_POST['password'];
$sql = "INSERT INTO myTable (user_name, password) VALUES ('$username', '$password')";
$retval = mysqli_query( $sql, $con2 );
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysqli_close($con2);
}
}
else
{
echo "No data input in php";
}
I have been stuck the last days on this one.
An add-on to the previous answers since I came across this concern:
If you really want to insert something like 24-May-2005
to your DATE column, you could do something like this:
INSERT INTO someTable(Empid,Date_Joined)
VALUES
('S710',STR_TO_DATE('24-May-2005', '%d-%M-%Y'));
In the above query please note that if it's May
(ie: the month in letters) the format should be %M
.
NOTE: I tried this with the latest MySQL version 8.0 and it works!
The problem I had was because I had made a database in my LocalDb.
If that's the case then you have to write is as shown below:
"SELECT * FROM <DatabaseName>.[dbo].[Projects]"
Replace with your database name.
You can probably also drop the "[ ]"
Since ASP.Net core 1.0 (vNext or whatever name is used for it) sessions are implemented differently.
I changed the session timeout value in Startup.cs
, void ConfigureServices
using:
services.AddSession(options => options.IdleTimeout = TimeSpan.FromSeconds(42));
Or if you want to use the appsettings.json
file, you can do something like:
// Appsettings.json
"SessionOptions": {
"IdleTimeout": "00:30:00"
}
// Startup.cs
services.AddSession(options => options.IdleTimeout = TimeSpan.Parse(Config.GetSection("SessionOptions")["IdleTimeout"]));
The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!
If you want to hide them anyway: error_reporting(0);
For the last Spring MVC app I wrote, I didn't inject the SecurityContext holder, but I did have a base controller that I had two utility methods related to this ... isAuthenticated() & getUsername(). Internally they do the static method call you described.
At least then it's only in once place if you need to later refactor.
I've recently been struggling with a related issue, discussed at length here: Order of legend entries in ggplot2 barplots with coord_flip() .
As it happens, the reason I had a hard time explaining my issue clearly, involved the relation between (the order of) factors and coord_flip(), as seems to be the case here.
I get the desired result by adding + xlim(rev(levels(x$variable)))
to the ggplot statement:
ggplot(x, aes(x=variable,y=value)) + geom_bar() +
scale_y_continuous("",formatter="percent") + coord_flip()
+ xlim(rev(levels(x$variable)))
This reverses the order of factors as found in the original data frame in the x-axis, which will become the y-axis with coord_flip(). Notice that in this particular example, the variable also happen to be in alphabetical order, but specifying an arbitrary order of levels within xlim()
should work in general.
At the end of foo()
, create a Timer
which calls foo()
itself after 10 seconds.
Because, Timer
create a new thread
to call foo()
.
You can do other stuff without being blocked.
import time, threading
def foo():
print(time.ctime())
threading.Timer(10, foo).start()
foo()

It looks like that many people use API keys as a security solution. The bottom line is: Never treat API keys as secret it is not. On https or not, whoever can read the request can see the API key and can make whatever call they want. An API Key should be just as a 'user' identifier as its not a complete security solution even when used with ssl.
The better description is in Eugene Osovetsky link to: When working with most APIs, why do they require two types of authentication, namely a key and a secret? Or check http://nordicapis.com/why-api-keys-are-not-enough/
It is saying you have an instance variable (the var is only visible/accessible when you have an instance of that class) and you are trying to use it in the context of a static scope (class method).
You can make your instance variable a class variable by adding static/class attribute.
You instantiate an instance of your class and call the instance method on that variable.
I think you need to run that .msi to install the dlls. After I ran that .msi I can go to (VS 2012) Add References > Assemblies > Extensions and all of the Microsoft.Office.Interop dlls are there.
On my computer the dlls are found in "c:\Program Files(x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA" so you could check in a similar/equivalent directory on yours just to make sure they're not there?
This is the best way for me:
jQuery:
$(document).ajaxStart(function() {
$(".loading").show();
});
$(document).ajaxStop(function() {
$(".loading").hide();
});
Coffee:
$(document).ajaxStart ->
$(".loading").show()
$(document).ajaxStop ->
$(".loading").hide()
You can use either of the following:
include "class.twitter.php";
or
require "class.twitter.php";
Using require
(or require_once
if you want to ensure the class is only loaded once during execution) will cause a fatal error to be raised if the file doesn't exist, whereas include
will only raise a warning. See http://php.net/require and http://php.net/include for more details
var cookie = 'your_cookie';
var cookie_value;
var i = request.headers.indexOf(cookie+'=');
if (i != -1) {
var eq = i+cookie.length+1;
var end = request.headers.indexOf(';', eq);
cookie_value = request.headers.substring(eq, end == -1 ? undefined : end);
}
don't you need double () for the values bit? if not try this (although there must be a better way
insert into this_table_archive (id, field_1, field_2, field_3)
values
((select id from this_table where entry_date < '2001-01-01'),
((select field_1 from this_table where entry_date < '2001-01-01'),
((select field_2 from this_table where entry_date < '2001-01-01'),
((select field_3 from this_table where entry_date < '2001-01-01'));
I found out that "git show --stat" is the best out of all here, gives you a brief summary of the commit, what files did you add and modify without giving you whole bunch of stuff, especially if you changed a lot files.
If you used ms build tools to install node the path is here:
C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\MSBuild\Microsoft\VisualStudio\NodeJs
pointers and references are two different thigngs.
A couple of things I have not seen mentioned.
A pointer is the address of something. A pointer can be stored and copied like any other variable. It thus have a size.
A reference should be seen as an ALIAS of something. It does not have a size and cannot be stored. It MUST reference something, ie. it cannot be null or changed. Well, sometimes the compiler needs to store the reference as a pointer, but that is an implementation detail.
With references you don't have the issues with pointers, like ownership handling, null checking, de-referencing on use.
JavaScript is a client-side language and your MySQL database is going to be running on a server.
So you have to rename your file to index.php
for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.
(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)
So after you renamed your file, go to the very top, before <html>
or <!DOCTYPE html>
and type:
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
/*Creating variables*/
$name = $_POST["name"];
$address = $_POST["address"];
$age = $_POST["age"];
$dbhost = "localhost"; /*most of the time it's localhost*/
$username = "yourusername";
$password = "yourpassword";
$dbname = "mydatabase";
$mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
$query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
mysqli_query($mysql, $query);
}
?>
<!DOCTYPE html>
<html>
<head>.......
....
<form method="post">
<input name="name" type="text"/>
<input name="address" type="text"/>
<input name="age" type="text"/>

You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:
pip install some-package.whl

With Swift 4, NSAttributedStringKey
has a static property called foregroundColor
. foregroundColor
has the following declaration:
static let foregroundColor: NSAttributedStringKey
The value of this attribute is a
UIColor
object. Use this attribute to specify the color of the text during rendering. If you do not specify this attribute, the text is rendered in black.
The following Playground code shows how to set the text color of an NSAttributedString
instance with foregroundColor
:
import UIKit
let string = "Some text"
let attributes = [NSAttributedStringKey.foregroundColor : UIColor.red]
let attributedString = NSAttributedString(string: string, attributes: attributes)
The code below shows a possible UIViewController
implementation that relies on NSAttributedString
in order to update the text and text color of a UILabel
from a UISlider
:
import UIKit
enum Status: Int {
case veryBad = 0, bad, okay, good, veryGood
var display: (text: String, color: UIColor) {
switch self {
case .veryBad: return ("Very bad", .red)
case .bad: return ("Bad", .orange)
case .okay: return ("Okay", .yellow)
case .good: return ("Good", .green)
case .veryGood: return ("Very good", .blue)
}
}
static let minimumValue = Status.veryBad.rawValue
static let maximumValue = Status.veryGood.rawValue
}
final class ViewController: UIViewController {
@IBOutlet weak var label: UILabel!
@IBOutlet weak var slider: UISlider!
var currentStatus: Status = Status.veryBad {
didSet {
// currentStatus is our model. Observe its changes to update our display
updateDisplay()
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Prepare slider
slider.minimumValue = Float(Status.minimumValue)
slider.maximumValue = Float(Status.maximumValue)
// Set display
updateDisplay()
}
func updateDisplay() {
let attributes = [NSAttributedStringKey.foregroundColor : currentStatus.display.color]
let attributedString = NSAttributedString(string: currentStatus.display.text, attributes: attributes)
label.attributedText = attributedString
slider.value = Float(currentStatus.rawValue)
}
@IBAction func updateCurrentStatus(_ sender: UISlider) {
let value = Int(sender.value.rounded())
guard let status = Status(rawValue: value) else { fatalError("Could not get Status object from value") }
currentStatus = status
}
}
Note however that you don't really need to use NSAttributedString
for such an example and can simply rely on UILabel
's text
and textColor
properties. Therefore, you can replace your updateDisplay()
implementation with the following code:
func updateDisplay() {
label.text = currentStatus.display.text
label.textColor = currentStatus.display.color
slider.value = Float(currentStatus.rawValue)
}
Well it depends on how you want to call this code.
Are you calling it from a button click on a form, if so then on the properties for the button on form, go to the Event tab, then On Click item, select [Event Procedure]. This will open the VBA code window for that button. You would then call your Module.Routine and then this would trigger when you click the button.
Similar to this:
Private Sub Command1426_Click()
mdl_ExportMorning.ExportMorning
End Sub
This button click event calls the Module mdl_ExportMorning
and the Public Sub ExportMorning
.
In my understanding you want to match a non-blank and non-empty string, so the top answer is doing the opposite. I suggest:
(.|\s)*\S(.|\s)*
- this matches any string containing at least one non-whitespace character (the \S
in the middle). It can be preceded and followed by anything, any char or whitespace sequence (including new lines) - (.|\s)*
.
You can try it with explanation on https://regex101.com/.
There's also the QueryString module's parse()
method:

queryString = require('querystring');
http.createServer(function (oRequest, oResponse) {
var oQueryParams;
// get query params as object
if (oRequest.url.indexOf('?') >= 0) {
oQueryParams = queryString.parse(oRequest.url.replace(/^.*\?/, ''));
// do stuff
console.log(oQueryParams);
}
oResponse.writeHead(200, {'Content-Type': 'text/plain'});
oResponse.end('Hello world.');

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)
You can get the length of any 2nd dimension array as z[n].length
where 0 <= n < z.length
.
If you're treating your 2D array as a matrix, you can simply get z.length
and z[0].length
, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).
Generally, no, do not define functions inside functions.
Unless you have a really good reason. Which you don't.
Why not?
lambda
expression instead.What is a really good reason to define functions inside functions?
When what you actually want is a dingdang closure.
Here I am considering Sunday as first & Saturday as last day of the week.
$m = strtotime('06-08-2012');
$today = date('l', $m);
$custom_date = strtotime( date('d-m-Y', $m) );
if ($today == 'Sunday') {
$week_start = date("d-m-Y", $m);
} else {
$week_start = date('d-m-Y', strtotime('this week last sunday', $custom_date));
}
if ($today == 'Saturday') {
$week_end = date("d-m-Y", $m);
} else {
$week_end = date('d-m-Y', strtotime('this week next saturday', $custom_date));
}
echo '<br>Start: '. $week_start;
echo '<br>End: '. $week_end;
Output :
Start: 05-08-2012
End: 11-08-2012
Well first of all I think rolling out your own solution for this all you need is urllib2 or httplib2 . Anyways in case you do require a generic REST client check this out .
https://github.com/scastillo/siesta
However i think the feature set of the library will not work for most web services because they shall probably using oauth etc .. . Also I don't like the fact that it is written over httplib which is a pain as compared to httplib2 still should work for you if you don't have to handle a lot of redirections etc ..
I always use the time-stamp - so its not possible, that the file exists already:
import os
import shutil
import datetime
now = str(datetime.datetime.now())[:19]
now = now.replace(":","_")
src_dir="C:\\Users\\Asus\\Desktop\\Versand Verwaltung\\Versand.xlsx"
dst_dir="C:\\Users\\Asus\\Desktop\\Versand Verwaltung\\Versand_"+str(now)+".xlsx"
shutil.copy(src_dir,dst_dir)
Beware of adding 3600!! may be a problem on day change because of unix timestamp format uses moth before day.
e.g. 2012-03-02 23:33:33 would become 2014-01-13 13:00:00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc.
This is not really a pure answer to the question, but an intelligent way to work around such problems:
instead of writing a complex file, simply delegate control to for instance a bash script like: makefile
foo : bar.cpp baz.h
bash script.sh
and script.sh looks like:
for number in 1 2 3 4
do
./a.out $number
done

You'll either have to upgrade the .NET 2 project to .NET 4, or downgrade the .NET 4 project to .NET 3.5 (or earlier).
How do you upgrade the .net version? I am not sure where to and what to specify. Please help.
Edit: I found the answer myself. Select the project, right click and choose Property Pages. There you can select framework version. or select the project and click Shift+F4
To do this for a specific target, you can do the following:
target_compile_definitions(my_target PRIVATE FOO=1 BAR=1)
You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.
Most generally (in case of jupyter not being in /local/bin) use,

This can be done easily and cleanly with float
.

The problem is that (as of 2016), for the password field, Firefox and Internet Explorer use the character "Black Circle" (?), which uses the Unicode code point 25CF
, but Chrome uses the character "Bullet" (•), which uses the Unicode code point 2022
.
As you can see, even in the StackOverflow font the two characters have different sizes.
The font you're using, "Lucida Sans Unicode", has an even greater disparity between the sizes of these two characters, leading to you noticing the difference.
The simple solution is to use a font in which both characters have similar sizes.
The fix could thus be to use a default font of the browser, which should render the characters in the password field just fine:
input[type="password"] {
font-family: caption;
}
I would suggest that you use a dictionary like so:
arr = {}
arr[1] = (1, 2, 4)
arr[18] = (3, 4, 5)
print(arr[1])
>>> (1, 2, 4)
If you're not sure an entry is defined in the dictionary, you'll need a validation mechanism when calling "arr[x]", e.g. try-except.
Please use !statusCheck.equals("success")
instead of !=
.
Here are more details.
The code you wrote will always return true
because state
cannot be both 10 and 15 for the statement to be false. if ((state != 10) && (state != 15)....
AND
is what you need not OR
.
Use $.inArray instead. This returns the index of the element in the array.
var statesArray = [10, 15, 19]; // list out all
var index = $.inArray(state, statesArray);
if(index == -1) {
console.log("Not there in array");
return true;
} else {
console.log("Found it");
return false;
}
Answer is simple. when u pass value from dropdown.
Just use as if else.
for eg:
foreach($result as $row) {
$GLOBALS['output'] .='<option value="'.$row["dropdownid"].'"'.
($GLOBALS['passselectedvalueid']==$row["dropwdownid"] ? ' Selected' : '').'
>'.$row['valueetc'].'</option>';

Sometimes using
instead of spaces will work. Clearly it has drawbacks, though.
First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.
For example,
> z <- factor(letters[c(3, 2, 3, 4)])
# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d
# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"
here, z
has 4 elements.
The index is 2, 1, 2, 3
in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.
Then, as.numeric
converts simply the index part of factor into numeric.
as.character
handles the index and levels, and generates character vector expressed by its level.
?as.numeric
says that Factors are handled by the default method.
Question: Check whether a $_POST value is empty.
Translation: Check to see if an array key/index has a value associated with it.
Answer: Depends on your emphasis on security. Depends on what is allowed as valid input.
1. Some people say use empty().
From the PHP Manual:
"[Empty] determines whether a variable is considered to be empty. A variable is considered empty if it does not exist or if its value equals FALSE."
The following are thus considered empty.
"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)
If none of these values are valid for your input control, then empty()
would work. The problem here is that empty()
might be too broad to be used consistently (the same way, for the same reason, on different input control submissions to $_POST
or $_GET
). A good use of empty()
is to check if an entire array is empty (has no elements).
2. Some people say use isset().
isset()
(a language construct) cannot operate on entire arrays, as in isset($myArray)
. It can only operate on variables and array elements (via the index/key): isset($var)
and isset($_POST['username'])
. The isset()
language construct does two things. First it checks to see if a variable or array index/key has a value associated with it. Second, it checks to make sure that value is not equal to the PHP NULL value.
In short, the most accurate check can be accomplished best with isset()
, as some input controls do not even register with $_POST when they are not selected or checked. I have never known a form that submitted the PHP NULL value. None of mine do, so I use isset()
to check if a $_POST
key has no value associated with it (and that is not NULL). isset()
is a much stricter test of emptiness (in the sense of your question) than empty()
.
3. Some people say just do if($var), if($myArray), or if($myArray['userName']) to determine emptiness.
You can test anything that evaluates to true or false in an if statement. Empty arrays evaluate to false and so do variables that are not set. Variables that contain the PHP NULL value also evaluate to false. Unfortunately in this case, like with
empty()
, many more things also evaluate to false: 1. the empty string '', zero (0), zero.zero (0.0), the string zero '0', boolean false, and certain empty XML objects.--Doyle, Beginning PHP 5.3
In conclusion, use isset()
and consider combining it with other tests. Example:
May not work due to superglobal screwiness, but would work for other arrays without question.
if (is_array($_POST) && !empty($_POST)) {
// Now test for your successful controls in $_POST with isset()
}
Hence, why look for a value associated with a key before you even know for sure that $_POST
represents an array and has any values stored in it at all (something many people fail to consider)? Remember, people can send data to your form without using a web browser. You may one day get to the point of testing that $_POST
only has the allowed keys, but that conversation is for another day.
Useful reference:
This isn't added out of the box because the Angular team wants Angular 2 to run minified. OrderBy runs off of reflection which breaks with minification. Check out Miško Heverey's response on the matter.
I've taken the time to create an OrderBy pipe that supports both single and multi-dimensional arrays. It also supports being able to sort on multiple columns of the multi-dimensional array.
<li *ngFor="let person of people | orderBy : ['-lastName', 'age']">{{person.firstName}} {{person.lastName}}, {{person.age}}</li>
This pipe does allow for adding more items to the array after rendering the page, and still sort the arrays with the new items correctly.
I have a write up on the process here.
And here's a working demo: http://fuelinteractive.github.io/fuel-ui/#/pipe/orderby and https://plnkr.co/edit/DHLVc0?p=info

This is known as a line magic in iPython. They are unique in that their arguments only extend to the end of the current line, and magics themselves are really structured for command line development. timeit
is used to time the execution of code.
If you wanted to see all of the magics you can use, you could simply type:
%lsmagic
to get a list of both line magics and cell magics.
Some further magic information from documentation here:
IPython has a system of commands we call magics that provide effectively a mini command language that is orthogonal to the syntax of Python and is extensible by the user with new commands. Magics are meant to be typed interactively, so they use command-line conventions, such as using whitespace for separating arguments, dashes for options and other conventions typical of a command-line environment.
Depending on whether you are in line or cell mode, there are two different ways to use %timeit
. Your question illustrates the first way:
In [1]: %timeit range(100)
vs.
In [1]: %%timeit
: x = range(100)

Here is my example of how to change the arrows for Slick Carousel in React to anything you would like. First you need to set the nextArrow and prevArrow in settings to a function then return a div in that function with whatever icon you would like to use. For mine I used Font Awesome. Then you will need to add a className in your icon, you will see that in the NextArrow and PrevArrow functions. Then add the scss code to customize whatever you would like.
JSX Code:
function NextArrow(props) {
const { style, onClick } = props;
return (
<div style={{ ...style, display: "block" }} onClick={onClick}>
<FontAwesomeIcon icon={faChevronRight} size="3x" className="slick-arrow-icon-right" />
</div>
);
}
function PrevArrow(props) {
const { style, onClick } = props;
return (
<div style={{ ...style, display: "block" }} onClick={onClick}>
<FontAwesomeIcon icon={faChevronLeft} size="3x" className="slick-arrow-icon-left" />
</div>
);
}
function SlickCarouselArrowChange(props) {
var settings = {
className: "slider variable-width",
dots: true,
infinite: true,
centerMode: true,
slidesToShow: 1,
slidesToScroll: 1,
variableWidth: true,
autoplay: true,
autoplaySpeed: 2000,
nextArrow: <NextArrow />,
prevArrow: <PrevArrow />,
};
return (
<div className="slick-slider">
<Slider {...settings}>
{props.searchResults.map((image, index) => (
<div key={index}>
<img src={image.urls.small} />{" "}
</div>
))}
</Slider>
</div>
);
}
SCSS Code:
.slick-arrow-icon-left,
.slick-arrow-icon-right {
position: absolute;
display: block;
cursor: pointer;
background: transparent;
color: black;
top: 50%;
-webkit-transform: translate(0, -50%);
-ms-transform: translate(0, -50%);
transform: translate(0, -50%);
padding: 0;
border: none;
outline: none;
transition: 0.5s ease-in-out;
&:hover,
&:focus {
outline: none;
background: transparent;
color: black;
font-size: 40px;
&::before {
opacity: 1;
}
}
}
.slick-arrow-icon-left {
left: -50px;
[dir="rtl"] & {
left: auto;
right: -50px;
}
}
.slick-arrow-icon-right {
right: -50px;
[dir="rtl"] & {

Source Code:
frame.setContentPane(newContents());
frame.revalidate(); // frame.pack() if you want to resize.
Remember, Java use 'copy reference by value' argument passing. So changing a variable wont change copies of the reference passed to other methods.
Also note JFrame
is very confusing in the name of usability. Adding a component or setting a layout (usually) performs the operation on the content pane. Oddly enough, getting the layout really does give you the frame's layout manager.
StringUtils.isBlank()
checks that each character of the string is a whitespace character (or that the string is empty or that it's null). This is totally different than just checking if the string is empty.
From the linked documentation:
Checks if a String is whitespace, empty ("") or null.
StringUtils.isBlank(null) = true StringUtils.isBlank("") = true StringUtils.isBlank(" ") = true StringUtils.isBlank("bob") = false StringUtils.isBlank(" bob ") = false
For comparison StringUtils.isEmpty:
StringUtils.isEmpty(null) = true
StringUtils.isEmpty("") = true
StringUtils.isEmpty(" ") = false
StringUtils.isEmpty("bob") = false
StringUtils.isEmpty(" bob ") = false
Warning: In java.lang.String.isBlank() and java.lang.String.isEmpty() work the same except they don't return true
for null
.
java.lang.String.isBlank()
(since Java 11)

I use zope.event. It's the most bare bones you can imagine. :-) In fact, here is the complete source code:

for subscriber in subscribers:
subscriber(event)
Note that you can't send messages between processes, for example. It's not a messaging system, just an event system, nothing more, nothing less.
The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:
A data frame of four rows:
df = pd.DataFrame({'A': [1,2,3,4]})
Now trying to assign a list/array of two elements to it:
df['B'] = [3,4] # or df['B'] = np.array([3,4])
Both errors out:
ValueError: Length of values does not match length of index
Because the data frame has four rows but the list and array has only two elements.
Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:
df['B'] = pd.Series([3,4])
df
# A B
#0 1 3.0
#1 2 4.0
#2 3 NaN # NaN because the value at index 2 and 3 doesn't exist in the Series
#3 4 NaN
For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:
df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))
# A B
#0 1 1.0
#1 2 5.0
#2 7 9.0
#3 8 NaN
You could use a CURSOR in this case:
DECLARE @id INT
DECLARE @name NVARCHAR(100)
DECLARE @getid CURSOR
SET @getid = CURSOR FOR
SELECT table.id,
table.name
FROM table
OPEN @getid
FETCH NEXT
FROM @getid INTO @id, @name
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC stored_proc @varName=@id, @otherVarName='test', @varForName=@name
FETCH NEXT
FROM @getid INTO @id, @name
END
CLOSE @getid
DEALLOCATE @getid
Modified to show multiple parameters from the table.

I found something useful, you might try this
android:ems
or setEms(n)
sets the width of a TextView to fit a text of n 'M' letters regardless of the actual text extension and text size. See wikipedia Em unit
but only when the layout_width
is set to "wrap_content"
. Other layout_width
values override the ems width setting.
Adding an android:textSize
attribute determines the physical width of the view to the textSize * length of a text of n 'M's set above.

I like Keith Hill's answer except it has a bug that prevents it from recursing past two levels. These commands manifest the bug:
New-Item level1/level2/level3/level4/foobar.txt -Force -ItemType file
cd level1
GetFiles . xyz | % { $_.fullname }
With Hill's original code you get this:
...\level1\level2
...\level1\level2\level3
Here is a corrected, and slightly refactored, version:
function GetFiles($path = $pwd, [string[]]$exclude)
{
foreach ($item in Get-ChildItem $path)
{
if ($exclude | Where {$item -like $_}) { continue }
$item
if (Test-Path $item.FullName -PathType Container)
{
GetFiles $item.FullName $exclude
}
}
}
With that bug fix in place you get this corrected output:
...\level1\level2
...\level1\level2\level3
...\level1\level2\level3\level4
...\level1\level2\level3\level4\foobar.txt
I also like ajk's answer for conciseness though, as he points out, it is less efficient. The reason it is less efficient, by the way, is because Hill's algorithm stops traversing a subtree when it finds a prune target while ajk's continues. But ajk's answer also suffers from a flaw, one I call the ancestor trap. Consider a path such as this that includes the same path component (i.e. subdir2) twice:
\usr\testdir\subdir2\child\grandchild\subdir2\doc
Set your location somewhere in between, e.g. cd \usr\testdir\subdir2\child
, then run ajk's algorithm to filter out the lower subdir2
and you will get no output at all, i.e. it filters out everything because of the presence of subdir2
higher in the path. This is a corner case, though, and not likely to be hit often, so I would not rule out ajk's solution due to this one issue.
Nonetheless, I offer here a third alternative, one that does not have either of the above two bugs. Here is the basic algorithm, complete with a convenience definition for the path or paths to prune--you need only modify $excludeList
to your own set of targets to use it:
$excludeList = @("stuff","bin","obj*")
Get-ChildItem -Recurse | % {
$pathParts = $_.FullName.substring($pwd.path.Length + 1).split("\");
if ( ! ($excludeList | where { $pathParts -like $_ } ) ) { $_ }
}
My algorithm is reasonably concise but, like ajk's, it is less efficient than Hill's (for the same reason: it does not stop traversing subtrees at prune targets). However, my code has an important advantage over Hill's--it can pipeline! It is therefore amenable to fit into a filter chain to make a custom version of Get-ChildItem while Hill's recursive algorithm, through no fault of its own, cannot. ajk's algorithm can be adapted to pipeline use as well, but specifying the item or items to exclude is not as clean, being embedded in a regular expression rather than a simple list of items that I have used.
I have packaged my tree pruning code into an enhanced version of Get-ChildItem. Aside from my rather unimaginative name--Get-EnhancedChildItem--I am excited about it and have included it in my open source Powershell library. It includes several other new capabilities besides tree pruning. Furthermore, the code is designed to be extensible: if you want to add a new filtering capability, it is straightforward to do. Essentially, Get-ChildItem is called first, and pipelined into each successive filter that you activate via command parameters. Thus something like this...
Get-EnhancedChildItem –Recurse –Force –Svn
–Exclude *.txt –ExcludeTree doc*,man -FullName -Verbose
... is converted internally into this:
Get-ChildItem | FilterExcludeTree | FilterSvn | FilterFullName
Each filter must conform to certain rules: accepting FileInfo and DirectoryInfo objects as inputs, generating the same as outputs, and using stdin and stdout so it may be inserted in a pipeline. Here is the same code refactored to fit these rules:
filter FilterExcludeTree()
{
$target = $_
Coalesce-Args $Path "." | % {
$canonicalPath = (Get-Item $_).FullName
if ($target.FullName.StartsWith($canonicalPath)) {
$pathParts = $target.FullName.substring($canonicalPath.Length + 1).split("\");
if ( ! ($excludeList | where { $pathParts -like $_ } ) ) { $target }
}
}
}
The only additional piece here is the Coalesce-Args function (found in this post by Keith Dahlby), which merely sends the current directory down the pipe in the event that the invocation did not specify any paths.
Because this answer is getting somewhat lengthy, rather than go into further detail about this filter, I refer the interested reader to my recently published article on Simple-Talk.com entitled Practical PowerShell: Pruning File Trees and Extending Cmdlets where I discuss Get-EnhancedChildItem at even greater length. One last thing I will mention, though, is another function in my open source library, New-FileTree, that lets you generate a dummy file tree for testing purposes so you can exercise any of the above algorithms. And when you are experimenting with any of these, I recommend piping to % { $_.fullname }
as I did in the very first code fragment for more useful output to examine.
We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext
.
In a standalone application, you can specify that as below
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");
Context ctx = new InitialContext(env);
But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext
as below
System.getProperty(Context.PROVIDER_URL);
and
these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work
InitialContext ctx = new InitialContext();
You can just add the word JOIN or add a ; after each line(as @pictchubbate said). Better this way because of readability and also you should not meddle DELETE with INSERT; it is easy to go south.
The last question is a matter of debate, but as far as I know yes you should close after a set of queries. This applies mostly to old plain mysql/php and not PDO, mysqli. Things get more complicated(and heated in debates) in these cases.
Finally, I would suggest either using PDO or some other method.
I was facing the same issue, here is line from error
File "/usr/lib/python3/dist-packages/numpy/lib/npyio.py", line 260, in __getitem__
So i solve the issue by updating "npyio.py" file. In npyio.py line 196 assigning value to allow_pickle so i update this line as
self.allow_pickle = True
In C, you can use the built in qsort
command:
int compare( const void* a, const void* b)
{
int int_a = * ( (int*) a );
int int_b = * ( (int*) b );
if ( int_a == int_b ) return 0;
else if ( int_a < int_b ) return -1;
else return 1;
}
qsort( a, 6, sizeof(int), compare )
see: http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/
To answer the second part of your question: an optimal (comparison based) sorting algorithm is one that runs with O(n log(n)) comparisons. There are several that have this property (including quick sort, merge sort, heap sort, etc.), but which one to use depends on your use case.
As a side note, you can sometime do better than O(n log(n)) if you know something about your data - see the wikipedia article on Radix Sort
(int)99.99999
It will be 99. Casting a double to an int does not round, it'll discard the fraction part.
You can have multiple tags when building the image:
$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .
Reference: https://docs.docker.com/engine/reference/commandline/build/#tag-image-t
stringByTrimmingCharactersInSet
only removes characters from the beginning and the end of the string, not the ones in the middle.
1) If you need to remove only a given character (say the space character) from your string, use:
[yourString stringByReplacingOccurrencesOfString:@" " withString:@""]
2) If you really need to remove a set of characters (namely not only the space character, but any whitespace character like space, tab, unbreakable space, etc), you could split your string using the whitespaceCharacterSet
then joining the words again in one string:
NSArray* words = [yourString componentsSeparatedByCharactersInSet :[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString* nospacestring = [words componentsJoinedByString:@""];
Note that this last solution has the advantage of handling every whitespace character and not only spaces, but is a bit less efficient that the stringByReplacingOccurrencesOfString:withString:
. So if you really only need to remove the space character and are sure you won't have any other whitespace character than the plain space char, use the first method.
I just tried to get path of shared preferences below like this.This is work for me.
File f = getDatabasePath("MyPrefsFile.xml");
if (f != null)
Log.i("TAG", f.getAbsolutePath());
You can also install Nodejs using NVM or Nodejs Version Manager There are a lot of benefits to using a version manager. One of them being you don't have to worry about this issue.
sudo apt-get update
sudo apt-get install build-essential libssl-dev
Once the prerequisite packages are installed, you can pull down the nvm installation script from the project's GitHub page. The version number may be different, but in general, you can download and install it with the following syntax:
curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh
This will download the script and run it. It will install the software into a subdirectory of your home directory at ~/.nvm
. It will also add the necessary lines to your ~/.profile
file to use the file.
To gain access to the nvm functionality, you'll need to log out and log back in again, or you can source the ~/.profile file so that your current session knows about the changes:
source ~/.profile
Now that you have nvm installed, you can install isolated Node.js versions.
To find out the versions of Node.js that are available for installation, you can type:
nvm ls-remote
. . .
v0.11.10
v0.11.11
v0.11.12
v0.11.13
v0.11.14
As you can see, the newest version at the time of this writing is v0.11.14. You can install that by typing:
nvm install 0.11.14
Usually, nvm will switch to use the most recently installed version. You can explicitly tell nvm to use the version we just downloaded by typing:
nvm use 0.11.14
When you install Node.js using nvm, the executable is called node. You can see the version currently being used by the shell by typing:
node -v

Attributes are static metadata. Assemblies, modules, types, members, parameters, and return values aren't first-class objects in C# (e.g., the System.Type
class is merely a reflected representation of a type). You can get an instance of an attribute for a type and change the properties if they're writable but that won't affect the attribute as it is applied to the type.
A very common issue not described yet that front-end coders often run into is the scope that is visible to an inline event handler in the HTML - for example, with
<button onclick="foo()"></button>
The scope of the variables that an on*
attribute can reference must be either:
querySelector
as a standalone variable will point to document.querySelector
; rare)Otherwise, you'll get a ReferenceError when the handler is invoked. So, for example, if the inline handler references a function which is defined inside window.onload
or $(function() {
, the reference will fail, because the inline handler may only reference variables in the global scope, and the function is not global:
window.addEventListener('DOMContentLoaded', () => {_x000D_
function foo() {_x000D_
console.log('foo running');_x000D_
}_x000D_
});
_x000D_
<button onclick="foo()">click</button>
_x000D_
Properties of the document
and properties of the element the handler is attached to may also be referenced as standalone variables inside inline handlers because inline handlers are invoked inside of two with
blocks, one for the document
, one for the element. The scope chain of variables inside these handlers is extremely unintuitive, and a working event handler will probably require a function to be global (and unnecessary global pollution should probably be avoided).
Since the scope chain inside inline handlers is so weird, and since inline handlers require global pollution to work, and since inline handlers sometimes require ugly string escaping when passing arguments, it's probably easier to avoid them. Instead, attach event handlers using Javascript (like with addEventListener
), rather than with HTML markup.
function foo() {_x000D_
console.log('foo running');_x000D_
}_x000D_
document.querySelector('.my-button').addEventListener('click', foo);
_x000D_
<button class="my-button">click</button>
_x000D_
On a different note, unlike normal <script>
tags, which run on the top level, code inside ES6 modules runs in its own private scope. A variable defined at the top of a normal <script>
tag is global, so you can reference it in other <script>
tags, like this:
<script>_x000D_
const foo = 'foo';_x000D_
</script>_x000D_
<script>_x000D_
console.log(foo);_x000D_
</script>
_x000D_
But the top level of an ES6 module is not global. A variable declared at the top of an ES6 module will only be visible inside that module, unless the variable is explicitly export
ed, or unless it's assigned to a property of the global object.
<script type="module">_x000D_
const foo = 'foo';_x000D_
</script>_x000D_
<script>_x000D_
// Can't access foo here, because the other script is a module_x000D_
console.log(typeof foo);_x000D_
</script>
_x000D_
The top level of an ES6 module is similar to that of the inside of an IIFE on the top level in a normal <script>
. The module can reference any variables which are global, and nothing can reference anything inside the module unless the module is explicitly designed for it.

Here is how to get the code for an embedded image without worrying about any files or base64 statements or mimes (it's still base64, but you don't have to do anything to get it). I originally posted this same answer in this thread, but it may be valuable to repeat it in this one, too.
To do this, you need Mozilla Thunderbird, you can fetch the html code for an image like this:

You can wrap this up into a string variable and place this absolutely anywhere that you would present an html email message - even in your email signatures. The advantage is that there are no attachments, and there are no links. (this code will display a lizard)
A picture is worth a thousand words:
Incidentally, I did write a program to do all of this for you. It's called BaseImage, and it will create the image code as well as the html for you. Please don't consider this self-promotion; I'm just sharing a solution.
Converting String array into stream and mapping to int is the best option available in java 8.
String[] stringArray = new String[] { "0", "1", "2" };
int[] intArray = Stream.of(stringArray).mapToInt(Integer::parseInt).toArray();
System.out.println(Arrays.toString(intArray));
Best way for me is:
Or you can push newly created branch on remote and merge there (if you do it this way, at the end you need to pull from remote master)
I opened this thread looking for a quick solution to a simple question, but I found that the answers here were either not helpful or overly complicated. The best way to get the last 5 chars of a string is, in fact, to use the Right() method. Here is a simple example:
Dim sMyString, sLast5 As String
sMyString = "I will be going to school in 2011!"
sLast5 = Right(sMyString, - 5)
MsgBox("sLast5 = " & sLast5)
If you're getting an error then there is probably something wrong with your syntax. Also, with the Right() method you don't need to worry much about going over or under the string length. In my example you could type in 10000 instead of 5 and it would just MsgBox the whole string, or if sMyString was NULL or "", the message box would just pop up with nothing.
I had the same issue, it turns that I had my project configured as many of you stated above, yet the problem persisted, so I went deeper and came across that I was using Apache Tomcat 6 as my Runtime Server, so the fix was simple, I just upgraded the project to use Apache Tomcat 7 and that's all, finally the IDE recognized javax.servlet.annotation.WebServlet annotation.
In Centos
sudo yum install php-xml
and restart apache
sudo service httpd restart
Analoguously to the two options (homebrew / manual) posted by @brismuth, here's the MacPorts way:
Install the Android SDK:
sudo port install android
Run the SDK manager:
sh /opt/local/share/java/android-sdk-macosx/tools/android
As @brismuth suggested, uncheck everything but Android SDK Platform-tools
(optional)
Install the packages, accepting licenses. Close the SDK Manager.
Add platform-tools
to your path; in MacPorts, they're in /opt/local/share/java/android-sdk-macosx/platform-tools
. E.g., for bash:
echo 'export PATH=$PATH:/opt/local/share/java/android-sdk-macosx/platform-tools' >> ~/.bash_profile
Refresh your bash profile (or restart your terminal/shell):
source ~/.bash_profile
Start using adb:
adb devices
A previous answer on this page describes how to use .htaccess to force all files of a certain type to download. However, the solution does not work with all file types across all browsers. This is a more reliable way:
<FilesMatch "\.(?i:csv)$">
ForceType application/octet-stream
Header set Content-Disposition attachment
</FilesMatch>
You might need to flush your browser cache to see this working correctly.
Even if you do start the executable outside Visual Studio, you can still use the "Attach" command to connect Visual Studio to your already-running executable. This can be useful e.g. when your application is run as a plug-in within another application.
You can choose any extension in the world if you setup Apache correctly. You could use .html to do PHP if you set up in your Apache config.
In conclusion, extension has nothing to do with the app or website itself. You can use the one you want, but normaly, use .php (to not reinvent the wheel)
But in 2019, you should use routing and forgot about extension at the end.
I recommend you using Laravel.
In answer to @KingCrunch: True, Apache not use it by default but you can easily use it if you change config. But this it not recommended since everybody know that it not really an option.
I already saw .html files that executed PHP using the html extension.
Try This:
int positionOfJPG=url.IndexOf(".jpg");
string newString = url.Substring(18, url.Length - positionOfJPG);
I was trying to connect to mysql from the python code that was executed using spark-submit
.
I was using HDP sandbox that was using Ambari. Tried lot of options such as --jars
, --driver-class-path
, etc, but none worked.
Copy the jar in /usr/local/miniconda/lib/python2.7/site-packages/pyspark/jars/
As of now I'm not sure if it's a solution or a quick hack, but since I'm working on POC so it kind of works for me.

This solution comes from my personal experience. We used several Amazon S3 buckets and one server for redirecting non-www
to www
domain names to match S3 "Host" header policy.
I used the following configuration for nginx server:
server {
listen 80;
server_name ~^(?!www\.)(?<domain>.+)$;
return 301 $scheme://www.$domain$request_uri;
}
This matches all domain names pointed to the server starting with whatever but www.
and redirects to www.<domain>
. In the same manner you can do opposite redirect from www
to non-www
.
Connect to the server first with a Windows ssh client that uses the known_hosts file. PuTTy stores the data in the windows registry,however OpenSSH uses the known_hosts file, and will add entries in there after you connect. Default location for the file is %USERPROFILE%.ssh. I hope this helps
The first day of week can be determined with help of java.util.Calendar
as follows:
Calendar calendar = Calendar.getInstance();
calendar.clear();
calendar.setTimeInMillis(timestamp);
while (calendar.get(Calendar.DAY_OF_WEEK) > calendar.getFirstDayOfWeek()) {
calendar.add(Calendar.DATE, -1); // Substract 1 day until first day of week.
}
long firstDayOfWeekTimestamp = calendar.getTimeInMillis();
The first day of month can be determined as follows:
Calendar calendar = Calendar.getInstance();
calendar.clear();
calendar.setTimeInMillis(timestamp);
while (calendar.get(Calendar.DATE) > 1) {
calendar.add(Calendar.DATE, -1); // Substract 1 day until first day of month.
}
long firstDayOfMonthTimestamp = calendar.getTimeInMillis();
Pretty verbose, yes.
Java 7 will come with a much improved Date and Time API (JSR-310). If you can't switch yet, then you can as far use JodaTime which makes it all less complicated:
DateTime dateTime = new DateTime(timestamp);
long firstDayOfWeekTimestamp = dateTime.withDayOfWeek(1).getMillis();
and
DateTime dateTime = new DateTime(timestamp);
long firstDayOfMonthTimestamp = dateTime.withDayOfMonth(1).getMillis();
The issue of being forced to trigger('change')
drove me nuts, as I had custom code in the change
trigger, which should only trigger when the user changes the option in the dropdown. IMO, change should not be triggered when setting an init value at the start.
I dug deep and found the following: https://github.com/select2/select2/issues/3620
Example:
$dropDown.val(1).trigger('change.select2');
You must specify the database to use on connect; if you want to use psql for your script, you can use "\c name_database"
user_name=# CREATE DATABASE testdatabase;
user_name=# \c testdatabase
At this point you might see the following output
You are now connected to database "testdatabase" as user "user_name".
testdatabase=#
Notice how the prompt changes. Cheers, have just been hustling looking for this too, too little information on postgreSQL compared to MySQL and the rest in my view.
As stated in an article by Slicehost:
User setup
So let's start by adding the main user to the Apache user group:
sudo usermod -a -G www-data demo
That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.
You will need to log out and log back in again to enable the group change.
Check the groups now:
groups ... # demo www-data
So now I am a member of two groups: My own (demo) and the Apache group (www-data).
Folder setup
Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).
Let's set that up:
sudo chgrp -R www-data /home/demo/public_html
As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.
If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.
Setgid
Good so far, but remember the command we just gave only affects existing folders. What about anything new?
We can set the ownership so anything new is also in the 'www-data' group.
The first command will change the permissions for the public_html directory to include the "setgid" bit:
sudo chmod 2750 /home/demo/public_html
That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.
If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:
sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads
The permissions only need to be set once as new files will automatically be assigned the correct ownership.
private ViewPager viewPager;
viewPager = (ViewPager) findViewById(R.id.pager);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}

public void onPageScrollStateChanged(int arg0) {

}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
If the numbers aren't supposed to be absurdly huge, maybe use:
new RegExp(
'^' + // No leading content.
'[-+]?' + // Optional sign.
'(?:[0-9]{0,30}\\.)?' + // Optionally 0-30 decimal digits of mantissa.
'[0-9]{1,30}' + // 1-30 decimal digits of integer or fraction.
'(?:[Ee][-+]?[1-2]?[0-9])?' + // Optional exponent 0-29 for scientific notation.
'$' // No trailing content.
)
This tries to avoid some scenarios, just in case:
1E-323
.Infinity
when a finite number is expected (try 1E309
or -1E309
).Change:

You are not initializing your String[]
. You either need to initialize it using the exact array size, as suggested by @Tr?nSiLong, or use a List<String>
and then convert to a String[]
(in case you do not know the length):
String[] title = {
"Abundance",
"Anxiety",
"Bruxism",
"Discipline",
"Drug Addiction"
};
String urlbase = "http://www.somewhere.com/data/";
String imgSel = "/logo.png";
List<String> mStrings = new ArrayList<String>();
for(int i=0;i<title.length;i++) {
mStrings.add(urlbase + title[i].toLowerCase() + imgSel);
System.out.println(mStrings[i]);
}
String[] strings = new String[mStrings.size()];
strings = mStrings.toArray(strings);//now strings is the resulting array
By encode, do you mean: Convert all applicable characters to HTML entities?
htmlspecialchars
or
htmlentities
You can also use strip_tags if you want to remove all HTML tags :
Note: this will NOT stop all XSS attacks
Your piece of script works just great. Are you sure you are not assigning anything else before the if to "i"?
A common mistake is also not to leave a space after and before the square brackets.

My Apps
and select your App from the dropdown. App Setting > Basic Tab
and then click "Add Platform" at bottom section.Site URL
(e.g. mywebsite.com
)http://localhost:8080/myfbsampleapp

You can simply achieve it by

I was also coming across this issue and for me when doing more updates more issues occurred.
What worked for me in the end was more or less to remove angular cli and re install it with these steps:
npm uninstall -g @angular/cli
npm cache clean --force
npm install -g @angular/cli
this helped me out source: how to uninstall angular/cli
I found possible answer. You have core-js version 3.0, and this version doesn't have separate folders for ES6 and ES7; that's why the application cannot find correct paths.
To resolve this error, you can downgrade the core-js version to 2.5.7. This version produces correct catalogs structure, with separate ES6 and ES7 folders.
To downgrade the version, simply run:
npm i -S [email protected]
In my case, with Angular, this works ok.
You can use <<
to append to a string in-place.
s = "foo"
old_id = s.object_id
s << "bar"
s #=> "foobar"
s.object_id == old_id #=> true
I resolved this problem, searching the dll's file in C:\Windows\assembly\GAC_MSIL\ and copied to bin directory of the proyect deployed. That work for me.
Use this. Beware of i's larger than 9, as these will require a char array with more than 2 elements to avoid a buffer overrun.
char c[2];
int i=1;
sprintf(c, "%d", i);
I know you can do it for MSIE and this limited example seems to work for firefox (not sure how extensible the technique is).
An alternative approach would involve storing the ranges in a table, instead of embedding them in the query. You would end up with a table, call it Ranges, that looks like this:
LowerLimit UpperLimit Range
0 9 '0-9'
10 19 '10-19'
20 29 '20-29'
30 39 '30-39'
And a query that looks like this:
Select
Range as [Score Range],
Count(*) as [Number of Occurences]
from
Ranges r inner join Scores s on s.Score between r.LowerLimit and r.UpperLimit
group by Range
This does mean setting up a table, but it would be easy to maintain when the desired ranges change. No code changes necessary!
If we want to copy an object in Java, there are two possibilities that we need to consider: a shallow copy and a deep copy.
The shallow copy is the approach when we only copy field values. Therefore, the copy might be dependent on the original object. In the deep copy approach, we make sure that all the objects in the tree are deeply copied, so the copy is not dependent on any earlier existing object that might ever change.
This question is the perfect definition for the application of the deep copy approach.
First, if you have a simple HashMap<Integer, List<T>>
map then we just create a workaround like this. Creating a new instance of the List<T>
.
public static <T> HashMap<Integer, List<T>> deepCopyWorkAround(HashMap<Integer, List<T>> original)
{
HashMap<Integer, List<T>> copy = new HashMap<>();
for (Map.Entry<Integer, List<T>> entry : original.entrySet()) {
copy.put(entry.getKey(), new ArrayList<>(entry.getValue()));
}
return copy;
}
This one uses Stream.collect()
method to create the clone map, but uses the same idea as the previous method.
public static <T> Map<Integer, List<T>> deepCopyStreamWorkAround(Map<Integer, List<T>> original)
{
return original
.entrySet()
.stream()
.collect(Collectors.toMap(Map.Entry::getKey, valueMapper -> new ArrayList<>(valueMapper.getValue())));
}
But, if the instances inside T
are also mutable objects we have a big problem. In this case a real deep copy is an alternative that solves this problem. Its advantage is that at least each mutable object in the object graph is recursively copied. Since the copy is not dependent on any mutable object that was created earlier, it won’t get modified by accident like we saw with the shallow copy.
To solve that this deep copy implementations will do the work.

I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["hard-core pornography"]; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.
MSDN seems to indicate that the Cxxx casts for specific types can improve performance in VB .NET because they are converted to inline code. For some reason, it also suggests DirectCast as opposed to CType in certain cases (the documentations states it's when there's an inheritance relationship; I believe this means the sanity of the cast is checked at compile time and optimizations can be applied whereas CType always uses the VB runtime.)
When I'm writing VB .NET code, what I use depends on what I'm doing. If it's prototype code I'm going to throw away, I use whatever I happen to type. If it's code I'm serious about, I try to use a Cxxx cast. If one doesn't exist, I use DirectCast if I have a reasonable belief that there's an inheritance relationship. If it's a situation where I have no idea if the cast should succeed (user input -> integers, for example), then I use TryCast so as to do something more friendly than toss an exception at the user.
One thing I can't shake is I tend to use ToString instead of CStr but supposedly Cstr is faster.
One way to insert text inside a rectangle is to insert a foreign object, wich is a DIV, inside rect object.
This way, the text will respct the limits of the DIV.
var g = d3.select("svg");_x000D_
_x000D_
g.append("rect")_x000D_
.attr("x", 0)_x000D_
.attr("y", 0)_x000D_

.attr("height","100%")_x000D_
.attr("fill","#000");_x000D_
_x000D_
_x000D_
var fo = g.append("foreignObject")_x000D_
.attr("width","100%");_x000D_

If you want to split only by newlines, you can use str.splitlines():
Example:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
With str.split() your case also works:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.split()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
However if you have spaces (or tabs) it will fail:
>>> data = """
... a, eqw, qwe
... v, ewr, err
... """
>>> data
'\na, eqw, qwe\nv, ewr, err\n'
>>> data.split()
['a,', 'eqw,', 'qwe', 'v,', 'ewr,', 'err']
$(".oSlider-rotate").slider({

max: 74,
step: .01,
value: 24,
slide: function(e,ui){
$('.user-text').css('transform', 'scale(' + ui.value + ')')
}
});
This will solve the issue
cPickle
comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle
, you can do this:
>>> import _pickle as cPickle
However, in 3.x, it's easier just to use pickle
.
No need to install anything. If something requires cPickle
in python 3.x, then that's probably a bug.
Do not use $scope.$apply()
angular already uses it and it can result in this error
$rootScope:inprog Action Already In Progress
if you use twice, use $timeout
or interval
I was having an issue recursively loading resources in my Spring app, and found that the issue was I should be using resource.getInputStream
. Here's an example showing how to recursively read in all files in config/myfiles
that are json
files.
private String myFilesResourceUrl = "config/myfiles/**/";
private String myFilesResourceExtension = "json";
ResourceLoader rl = new ResourceLoader();
// Recursively get resources that match.
// Big note: If you decide to iterate over these,
// use resource.GetResourceAsStream to load the contents
// or use the `readFileResource` of the ResourceLoader class.
Resource[] resources = rl.getResourcesInResourceFolder(myFilesResourceUrl, myFilesResourceExtension);
// Recursively get resource and their contents that match.
// This loads all the files into memory, so maybe use the same approach
// as this method, if need be.
Map<Resource,String> contents = rl.getResourceContentsInResourceFolder(myFilesResourceUrl, myFilesResourceExtension);
import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;
import org.springframework.util.StreamUtils;
public class ResourceLoader {
public Resource[] getResourcesInResourceFolder(String folder, String extension) {
ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
try {
String resourceUrl = folder + "/*." + extension;
Resource[] resources = resolver.getResources(resourceUrl);
return resources;
} catch (IOException e) {
throw new RuntimeException(e);
}
}
public String readResource(Resource resource) throws IOException {
try (InputStream stream = resource.getInputStream()) {
return StreamUtils.copyToString(stream, Charset.defaultCharset());
}
}
public Map<Resource, String> getResourceContentsInResourceFolder(
String folder, String extension) {
Resource[] resources = getResourcesInResourceFolder(folder, extension);
HashMap<Resource, String> result = new HashMap<>();
for (var resource : resources) {
try {
String contents = readResource(resource);
result.put(resource, contents);
} catch (IOException e) {
throw new RuntimeException("Could not load resource=" + resource + ", e=" + e);
}
}
return result;
}
}
If you are using "HttpClient", and you don't want to use global configuration to affect all you program you can use:
HttpClientHandler httpClientHandler = new HttpClientHandler();
httpClient.DefaultRequestHeaders.ExpectContinue = false;
I you are using "WebClient" I think you can try to remove this header by calling:
var client = new WebClient();
client.Headers.Remove(HttpRequestHeader.Expect);
You can try 'onbeforeunload
' event.
Also take a look at this-
Simplest way.
Just stop execution in 10 sec.
Create table SQL_test ( ID INT IDENTITY(1,1), UserName varchar(100))
while 1=1
insert into SQL_test values ('TEST')
Only MyISAM allows for FULLTEXT, as seen here.
Try this:
CREATE TABLE gamemech_chat (
id bigint(20) unsigned NOT NULL auto_increment,
from_userid varchar(50) NOT NULL default '0',
to_userid varchar(50) NOT NULL default '0',
text text NOT NULL,
systemtext text NOT NULL,
timestamp datetime NOT NULL default '0000-00-00 00:00:00',
chatroom bigint(20) NOT NULL default '0',
PRIMARY KEY (id),
KEY from_userid (from_userid),
FULLTEXT KEY from_userid_2 (from_userid),
KEY chatroom (chatroom),
KEY timestamp (timestamp)
) ENGINE=MyISAM;
I am currently creating plugins for a retail software brand, which are actually .net class libraries. As a requirement, each plugin needs to be configured using a config file. After a bit of research and testing, I compiled the following class. It does the job flawlessly. Note that I haven't implemented local exception handling in my case because, I catch exceptions at a higher level.
Some tweaking maybe needed to get the decimal point right, in case of decimals and doubles, but it works fine for my CultureInfo...
static class Settings
{
static UriBuilder uri = new UriBuilder(Assembly.GetExecutingAssembly().CodeBase);
static Configuration myDllConfig = ConfigurationManager.OpenExeConfiguration(uri.Path);
static AppSettingsSection AppSettings = (AppSettingsSection)myDllConfig.GetSection("appSettings");
static NumberFormatInfo nfi = new NumberFormatInfo()
{
NumberGroupSeparator = "",
CurrencyDecimalSeparator = "."
};
public static T Setting<T>(string name)
{
return (T)Convert.ChangeType(AppSettings.Settings[name].Value, typeof(T), nfi);
}
}
App.Config file sample
<add key="Enabled" value="true" />
<add key="ExportPath" value="c:\" />
<add key="Seconds" value="25" />
<add key="Ratio" value="0.14" />
Usage:
somebooleanvar = Settings.Setting<bool>("Enabled");
somestringlvar = Settings.Setting<string>("ExportPath");
someintvar = Settings.Setting<int>("Seconds");
somedoublevar = Settings.Setting<double>("Ratio");

As xanatos said, this is a misuse of ForEach.
If you are going to use linq to handle this, I would do it like this:
var departments = employees.SelectMany(x => x.Departments);
foreach (var item in departments)
{
item.SomeProperty = null;
}
collection.AddRange(departments);
However, the Loop approach is more readable and therefore more maintainable.
An object of a class cannot be set to NULL; however, you can set a pointer (which contains a memory address of an object) to NULL.
Example of what you can't do which you are asking:
Cat c;
c = NULL;//Compiling error
Example of what you can do:
Cat c;
//Set p to hold the memory address of the object c
Cat *p = &c;
//Set p to hold NULL
p = NULL;
you may want to put a break; after your location:
header("HTTP/1.1 301 Moved Permanently");
header('Location: '. $YourArrayName["YourURL"] );
break;
You just need the jQuery UI effects-core (13KB), to enable the duration of the adding (just like Omar Tariq it pointed out)
For those who uses ionic, go to [project name]/platforms/android/cordova/lib/builders/GradleBuilder.js
on line 164 you will see the following: var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-2.13-all.zip';
This line is used to create your gradle-wrapper.properties
, so any changes to the gradle-wrapper.properties
wont matter. All you need to do is change the url to the latest version, sync the gradle and the problem is solved.
Just want to change the gradle version in the Android studio, go to File>settings>project
and change the gradle version. After you apply, it will sync the project and you are ready to build.
