Taking Milad's suggestion a bit further, you can break your document source down and then do another find, continuing until you find the unmatched culprit.
When you are working with many modules (using a CMS), or don't have access to the W3C tool (because you are working locally), this approach is really helpful.
You are attempting to attach an event listener function before the element is loaded. Place fun()
inside an onload
event listener function. Call f1()
within this function, as the onclick
attribute will be ignored.
function f1() {
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
}
window.onload = function() {
document.getElementById("Save").onclick = function fun() {
alert("hello");
f1();
//validation code to see State field is mandatory.
}
}
DDL stands for Data Definition Language. DDL is used for defining structure of the table such as create a table or adding a column to table and even drop and truncate table. DML stands for Data Manipulation Language. As the name suggest DML used for manipulating the data of table. There are some commands in DML such as insert and delete.
With ES6 you can now do it like this
Example Codepen URl to load
const iframe = '<iframe height="265" style="width: 100%;" scrolling="no" title="fx." src="//codepen.io/ycw/embed/JqwbQw/?height=265&theme-id=0&default-tab=js,result" frameborder="no" allowtransparency="true" allowfullscreen="true">See the Pen <a href="https://codepen.io/ycw/pen/JqwbQw/">fx.</a> by ycw(<a href="https://codepen.io/ycw">@ycw</a>) on <a href="https://codepen.io">CodePen</a>.</iframe>';
A function component to load Iframe
function Iframe(props) {
return (<div dangerouslySetInnerHTML={ {__html: props.iframe?props.iframe:""}} />);
}
Usage:
import React from "react";
import ReactDOM from "react-dom";
function App() {
return (
<div className="App">
<h1>Iframe Demo</h1>
<Iframe iframe={iframe} />,
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
Edit on CodeSandbox:
The following also seems to work :
for (vector<int>::iterator it = res.begin(); it != res.end(); it++)
{
res.erase(it--);
}
Not sure if there's any flaw in this ?
You don't need to use the asterisk to accept a list.
Simply give the argument a name in the definition, and pass in a list like
def takes_list(a_list):
for item in a_list:
print item
Here is the way I include lots of classes from several folders in PHP 5. This will only work if you have classes though.
/*Directories that contain classes*/
$classesDir = array (
ROOT_DIR.'classes/',
ROOT_DIR.'firephp/',
ROOT_DIR.'includes/'
);
function __autoload($class_name) {
global $classesDir;
foreach ($classesDir as $directory) {
if (file_exists($directory . $class_name . '.php')) {
require_once ($directory . $class_name . '.php');
return;
}
}
}
Don't give exact heights, but relative ones, adding up to 100%. For example:
#content {height: 80%;}
#footer {height: 20%;}
Add in
html, body {height: 100%;}
In Swift
extension String {
var isPhoneNumber: Bool {
let PHONE_REGEX = "^[7-9][0-9]{9}$";
let phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
let result = phoneTest.evaluate(with: self)
return result
}
}
var Line = textBox1.Text + "," + textBox2.Text;
File.AppendAllText(@"C:\Documents\m2.txt", Line + Environment.NewLine);
Try this,
IFS=''
while read line
do
echo $line
done < file.txt
EDIT:
From man bash
IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with the read builtin command. The default value is
``<space><tab><newline>''
If you also have jQuery UI, you can add this:
$(document).ready(function () {
$(document).tooltip();
});
You then need a title instead of a hidden input. RGraham already posted an answer doing this for you :P
If you are using Python, I would suggest by exploring the request object:
dir(request)
Since the object support the method dict:
request.__dict__
It can be printed or saved. I use it to log 404 codes in Flask:
@app.errorhandler(404)
def not_found(e):
with open("./404.csv", "a") as f:
f.write(f'{datetime.datetime.now()},{request.__dict__}\n')
return send_file('static/images/Darknet-404-Page-Concept.png', mimetype='image/png')
From Git v1.7.8 to v1.8.5.6, you can use this:
git fetch <remote> --prune --tags
This doesn't work on newer versions of git (starting with v1.9.0) because of commit e66ef7ae6f31f2. I don't really want to delete it though since it did work for some people.
As suggested by "Chad Juliano", with all Git version since v1.7.8, you can use the following command:
git fetch --prune <remote> +refs/tags/*:refs/tags/*
You may need to enclose the tags part with quotes (on Windows for example) to avoid wildcard expansion:
git fetch --prune <remote> "+refs/tags/*:refs/tags/*"
This has always been my approach to this little nuisance. Note the use of VirtualPathUtility.ToAbsolute(relativeUrl) allows the method to be declared as an extension in a static class.
/// <summary>
/// Converts the provided app-relative path into an absolute Url containing the
/// full host name
/// </summary>
/// <param name="relativeUrl">App-Relative path</param>
/// <returns>Provided relativeUrl parameter as fully qualified Url</returns>
/// <example>~/path/to/foo to http://www.web.com/path/to/foo</example>
public static string ToAbsoluteUrl(this string relativeUrl) {
if (string.IsNullOrEmpty(relativeUrl))
return relativeUrl;
if (HttpContext.Current == null)
return relativeUrl;
if (relativeUrl.StartsWith("/"))
relativeUrl = relativeUrl.Insert(0, "~");
if (!relativeUrl.StartsWith("~/"))
relativeUrl = relativeUrl.Insert(0, "~/");
var url = HttpContext.Current.Request.Url;
var port = url.Port != 80 ? (":" + url.Port) : String.Empty;
return String.Format("{0}://{1}{2}{3}",
url.Scheme, url.Host, port, VirtualPathUtility.ToAbsolute(relativeUrl));
}
It says timer() is not available on android? You might find this article useful.
http://developer.android.com/resources/articles/timed-ui-updates.html
I was wrong. Timer() is available. It seems you either implement it the way it is one shot operation:
schedule(TimerTask task, Date when) // Schedule a task for single execution.
Or you cancel it after the first execution:
cancel() // Cancels the Timer and all scheduled tasks.
Select the range of cells, type in the value and press Ctrl + Enter.
This, of course, is true if you want to do it manually.
Just for reference, a for
loop can be used after getting the first row to get the rest of the file:
with open('file.csv', newline='') as f:
reader = csv.reader(f)
row1 = next(reader) # gets the first line
for row in reader:
print(row) # prints rows 2 and onward
Here's a complete example:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#if defined(__APPLE__)
# define COMMON_DIGEST_FOR_OPENSSL
# include <CommonCrypto/CommonDigest.h>
# define SHA1 CC_SHA1
#else
# include <openssl/md5.h>
#endif
char *str2md5(const char *str, int length) {
int n;
MD5_CTX c;
unsigned char digest[16];
char *out = (char*)malloc(33);
MD5_Init(&c);
while (length > 0) {
if (length > 512) {
MD5_Update(&c, str, 512);
} else {
MD5_Update(&c, str, length);
}
length -= 512;
str += 512;
}
MD5_Final(digest, &c);
for (n = 0; n < 16; ++n) {
snprintf(&(out[n*2]), 16*2, "%02x", (unsigned int)digest[n]);
}
return out;
}
int main(int argc, char **argv) {
char *output = str2md5("hello", strlen("hello"));
printf("%s\n", output);
free(output);
return 0;
}
I'm using the follow code to get Python 2 and 3 compatibility
if sys.version_info < (3, 0):
input = raw_input
Simply run a while loop that will continue to loop (and increase the number) until the number is divisible by 6.
while ($number % 6 != 0) {
$number++;
}
late to the party here; however just wanted to add a bit of extra fun..
box-shadow: 0px 0px 5px rgba(0,0,0,.3);
padding:7px;
will give you a nice looking padded in image. The padding will give you a simulated white border (or whatever border you have set). the rgba is just allowing you to do an opicity on the particular color; 0,0,0 being black. You could just as easily use any other RGB color.
Hope this helps someone!
The correct SQL connection string for SQL with specify port is use comma between ip address and port number like following pattern: xxx.xxx.xxx.xxx,yyyy
sys.argv is a list containing the script path and command line arguments; i.e. sys.argv[0] is the path of the script you're running and all following members are arguments.
If you want to run test methods in a specific order in JUnit 5, you can use the below code.
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
public class MyClassTest {
@Test
@Order(1)
public void test1() {}
@Test
@Order(2)
public void test2() {}
}
You always can do a session flush. Flush will synchronize the state of all your objects in session (please, someone correct me if i'm wrong), and maybe it would solve your problem in some cases.
Implementing your own equals and hashcode may help you too.
Originally javax
was intended to be for extensions, and sometimes things would be promoted out of javax
into java.
One issue was Netscape (and probably IE) limiting classes that could be in the java package.
When Swing was set to "graduate" to java
from javax
there was sort of a mini-blow up because people realized that they would have to modify all of their imports. Given that backwards compatibility is one of the primary goals of Java they changed their mind.
At that point in time, at least for the community (maybe not for Sun) the whole point of javax
was lost. So now we have some things in javax that probably should be in java
... but aside from the people that chose the package names I don't know if anyone can figure out what the rationale is on a case-by-case basis.
put file slf4j-log4j12-1.6.4.jar
in the classpath will do the trick.
You can also use astyle
. I found it quite useful and it has several options too:
Tab and Bracket Options:
If no indentation option is set, the default option of 4 spaces will be used. Equivalent to -s4 --indent=spaces=4. If no brackets option is set, the
brackets will not be changed.
--indent=spaces, --indent=spaces=#, -s, -s#
Indent using # spaces per indent. Between 1 to 20. Not specifying # will result in a default of 4 spaces per indent.
--indent=tab, --indent=tab=#, -t, -t#
Indent using tab characters, assuming that each tab is # spaces long. Between 1 and 20. Not specifying # will result in a default assumption of
4 spaces per tab.`
I think you should be able to use a default route handler and redirect from there to a page outside the app, as detailed below:
const ROUTER_INSTANCE = new VueRouter({
mode: "history",
routes: [
{ path: "/", component: HomeComponent },
// ... other routes ...
// and finally the default route, when none of the above matches:
{ path: "*", component: PageNotFound }
]
})
In the above PageNotFound
component definition, you can specify the actual redirect, that will take you out of the app entirely:
Vue.component("page-not-found", {
template: "",
created: function() {
// Redirect outside the app using plain old javascript
window.location.href = "/my-new-404-page.html";
}
}
You may do it either on created
hook as shown above, or mounted
hook also.
Please note:
I have not verified the above. You need to build a production version of app, ensure that the above redirect happens. You cannot test this in vue-cli
as it requires server side handling.
Usually in single page apps, server sends out the same index.html along with app scripts for all route requests, especially if you have set <base href="/">
. This will fail for your /404-page.html
unless your server treats it as a special case and serves the static page.
Let me know if it works!
Update for Vue 3 onward:
You'll need to replace the '*'
path property with '/:pathMatch(.*)*'
if you're using Vue 3 as the old catch-all path of '*'
is no longer supported. The route would then look something like this:
{ path: '/:pathMatch(.*)*', component: PathNotFound },
See the docs for more info on this update.
on windows,
pip install --upgrade spyder
in powershell, start python shell, by typing python

That't it.
Based on stdOrgnlDave answer I have defined this wrapper that it can be called with optional kinds so the encoder will work only for certain kinds inside your projects. I believe the work should be done inside your code and not to use this "default" encoder since "it is better explicit than implicit", but I understand using this will save some of your time. :-)
import time
import json
import decimal
from uuid import UUID
from datetime import datetime
def JSONEncoder_newdefault(kind=['uuid', 'datetime', 'time', 'decimal']):
'''
JSON Encoder newdfeault is a wrapper capable of encoding several kinds
Use it anywhere on your code to make the full system to work with this defaults:
JSONEncoder_newdefault() # for everything
JSONEncoder_newdefault(['decimal']) # only for Decimal
'''
JSONEncoder_olddefault = json.JSONEncoder.default
def JSONEncoder_wrapped(self, o):
'''
json.JSONEncoder.default = JSONEncoder_newdefault
'''
if ('uuid' in kind) and isinstance(o, uuid.UUID):
return str(o)
if ('datetime' in kind) and isinstance(o, datetime):
return str(o)

return datetime.fromtimestamp(time.mktime(o))

I wrote a little jQuery extension for this:
$.fn.nl2brText = function (sText) {
var bReturnValue = 'undefined' == typeof sText;
if(bReturnValue) {
sText = $('<pre>').html(this.html().replace(/<br[^>]*>/i, '\n')).text();
}
var aElms = [];
sText.split(/\r\n|\r|\n/).forEach(function(sSubstring) {
if(aElms.length) {
aElms.push(document.createElement('br'));
}
aElms.push(document.createTextNode(sSubstring));
});
var $aElms = $(aElms);
if(bReturnValue) {
return $aElms;
}
return this.empty().append($aElms);
};
Another option would be to use an existing plugin.
For example persisto is an open source project that provides an easy interface to localStorage/sessionStorage and automates persistence for form fields (input, radio buttons, and checkboxes).

Explanation:
Step 1: int fun(int);
Here we declare the prototype of the function fun()
.
Step 2: int i = fun(10);
The variable i is declared as an integer type and the result of the fun(10)
will be stored in the variable i
.
Step 3: int fun(int i){ return (i++); }
Inside the fun()
we are returning a value return(i++)
. It returns 10
. because i++
is the post-increement operator.
Step 4: Then the control back to the main function and the value 10
is assigned to variable i
.
Step 5: printf("%d\n", --i);
Here --i
denoted pre-increement. Hence it prints the value 9
.
Here is the App Bit Web Server (PHP,MySQL,PMA)
It can run a variety of CMS like Wordpress, Joomla, Drupal, Prestashop, etc. Besides CMS can also run PHP frameworks like Code Igniter, YII, CakePHP, etc. It is the same as WAMP or LAMP or XAMPP on your computer or laptop, but this is for android devices with lighttpd instead of apache.
This kind of error can be caused by LF vs CRLF line ending mismatches, e.g. when you're looking at the patch file and you're absolutely sure it should be able to apply, but it just won't.
To test this out, if you have a patch that applies to just one file, you can try running 'unix2dos' or 'dos2unix' on just that file (try both, to see which one causes the file to change; you can get these utilities for Windows as well as Unix), then commit that change as a test commit, then try applying the patch again. If that works, that was the problem.
NB git am
applies patches as LF by default (even if the patch file contains CRLF), so if you want to apply CRLF patches to CRLF files you must use git am --keep-cr
, as per this answer.
The child process environment is lost in the moment it ceases to exist, and moving the environment content from there to the parent is somewhat tricky.
You probably need to spawn a shell script (you can generate one dynamically to /tmp) which will output the virtualenv environment variables to a file, which you then read in the parent Python process and put in os.environ.
Or you simply parse the activate script in using for the line in open("bin/activate"), manually extract stuff, and put in os.environ. It is tricky, but not impossible.
The magic you have been looking for has been added in Rails 6
Now you can upsert (update or insert).
For single record use:
Model.upsert(column_name: value)
For multiple records use upsert_all :
Model.upsert_all(column_name: value, unique_by: :column_name)
Note:
Alright, this doesn't apply to the OP's exact situation, but for anyone like myself who comes here facing a similar issue, figure I should throw this out there-- maybe save a headache or two.
If you're using an non-standard "button" to ensure the submit
event isn't called:
<form>
<input type="hidden" name="hide" value="1">
<a href="#" onclick="submitWithChecked(this.form)">Hide Selected</a>
</form>
Then, when you try to access this.form
in the script, it's going to come up undefined. As I discovered, apparently anchor elements don't have same access to a parent form
element the way your standard form elements do.
In such cases, (again, assuming you are intentionally avoiding the submit
event for the time-being), you can use a button
with type="button"
<form>
<input type="hidden" name="hide" value="1">
<button type="button" onclick="submitWithChecked(this.form)">Hide Selected</a>
</form>
(Addendum 2020: All these years later, I think the more important lesson to take away from this is to check your input. If my function had bothered to check that the argument it received was actually a form element, the problem would have been much easier to catch.)
I faced the same problem when i tried to open my old c# project into visual studio 2017 version. This problem arises typically when you try to open a project that you made with previous version of VS and open it with latest version. what i did is,i opened my project and delete the reference from my project,then added Microsoft outlook 12.0 object library and Microsoft office 12.0 object libraryMicrosoft outlook 12.0 object library
just indent your code correctly:
def determine_period(universe_array):
period=0
tmp=universe_array
while True:
tmp=apply_rules(tmp)#aplly_rules is a another function
period+=1
if numpy.array_equal(tmp,universe_array) is True:
return period
if period>12: #i wrote this line to stop it..but seems its doesnt work....help..
return 0
else:
return period
You need to understand that the break
statement in your example will exit the infinite loop you've created with while True
. So when the break condition is True, the program will quit the infinite loop and continue to the next indented block. Since there is no following block in your code, the function ends and don't return anything. So I've fixed your code by replacing the break
statement by a return
statement.
Following your idea to use an infinite loop, this is the best way to write it:
def determine_period(universe_array):
period=0
tmp=universe_array
while True:
tmp=apply_rules(tmp)#aplly_rules is a another function
period+=1
if numpy.array_equal(tmp,universe_array) is True:
break
if period>12: #i wrote this line to stop it..but seems its doesnt work....help..
period = 0
break
return period
I answered this question: How to secure an ASP.NET Web API 4 years ago using HMAC.
Now, lots of things changed in security, especially that JWT is getting popular. In this answer, I will try to explain how to use JWT in the simplest and basic way that I can, so we won't get lost from jungle of OWIN, Oauth2, ASP.NET Identity... :)
If you don't know about JWT tokens, you need to take a look at:
https://tools.ietf.org/html/rfc7519
Basically, a JWT token looks like this:
<base64-encoded header>.<base64-encoded claims>.<base64-encoded signature>
Example:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1bmlxdWVfbmFtZSI6ImN1b25nIiwibmJmIjoxNDc3NTY1NzI0LCJleHAiOjE0Nzc1NjY5MjQsImlhdCI6MTQ3NzU2NTcyNH0.6MzD1VwA5AcOcajkFyKhLYybr3h13iZjDyHm9zysDFQ
A JWT token has three sections:
If you use the website jwt.io with the token above, you can decode the token and see it like below:
Technically, JWT uses a signature which is signed from headers and claims with security algorithm specified in the headers (example: HMACSHA256). Therefore, JWT must be transferred over HTTPs if you store any sensitive information in its claims.
Now, in order to use JWT authentication, you don't really need an OWIN middleware if you have a legacy Web Api system. The simple concept is how to provide JWT token and how to validate the token when the request comes. That's it.
In the demo I've created (github), to keep the JWT token lightweight, I only store username
and expiration time
. But this way, you have to re-build new local identity (principal) to add more information like roles, if you want to do role authorization, etc. But, if you want to add more information into JWT, it's up to you: it's very flexible.
Instead of using OWIN middleware, you can simply provide a JWT token endpoint by using a controller action:
public class TokenController : ApiController
{
// This is naive endpoint for demo, it should use Basic authentication
// to provide token or POST request
[AllowAnonymous]
public string Get(string username, string password)
{
if (CheckUser(username, password))
{
return JwtManager.GenerateToken(username);
}
throw new HttpResponseException(HttpStatusCode.Unauthorized);
}
public bool CheckUser(string username, string password)
{
// should check in the database
return true;
}
}
This is a naive action; in production you should use a POST request or a Basic Authentication endpoint to provide the JWT token.
username
?You can use the NuGet package called System.IdentityModel.Tokens.Jwt
from Microsoft to generate the token, or even another package if you like. In the demo, I use HMACSHA256
with SymmetricKey
:
/// <summary>
/// Use the below code to generate symmetric Secret Key
/// var hmac = new HMACSHA256();
/// var key = Convert.ToBase64String(hmac.Key);
/// </summary>
private const string Secret = "db3OIsj+BXE9NZDy0t8W3TcNekrF+2d/1sFnWG4HnV8TZY30iTOdtVWJG8abWvB1GlOgJuQZdcF2Luqm/hccMw==";
public static string GenerateToken(string username, int expireMinutes = 20)
{
var symmetricKey = Convert.FromBase64String(Secret);
var tokenHandler = new JwtSecurityTokenHandler();
var now = DateTime.UtcNow;
var tokenDescriptor = new SecurityTokenDescriptor
{
Subject = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Name, username)
}),
Expires = now.AddMinutes(Convert.ToInt32(expireMinutes)),
SigningCredentials = new SigningCredentials(
new SymmetricSecurityKey(symmetricKey),
SecurityAlgorithms.HmacSha256Signature)
};
var stoken = tokenHandler.CreateToken(tokenDescriptor);
var token = tokenHandler.WriteToken(stoken);
return token;
}
The endpoint to provide the JWT token is done.
In the demo, I have built
JwtAuthenticationAttribute
which inherits from IAuthenticationFilter
(more detail about authentication filter in here).
With this attribute, you can authenticate any action: you just have to put this attribute on that action.
public class ValueController : ApiController
{
[JwtAuthentication]
public string Get()
{
return "value";
}
}
You can also use OWIN middleware or DelegateHander if you want to validate all incoming requests for your WebAPI (not specific to Controller or action)
Below is the core method from authentication filter:
private static bool ValidateToken(string token, out string username)
{
username = null;
var simplePrinciple = JwtManager.GetPrincipal(token);
var identity = simplePrinciple.Identity as ClaimsIdentity;
if (identity == null)
return false;
if (!identity.IsAuthenticated)
return false;
var usernameClaim = identity.FindFirst(ClaimTypes.Name);
username = usernameClaim?.Value;
if (string.IsNullOrEmpty(username))
return false;
// More validate to check whether username exists in system
return true;
}
protected Task<IPrincipal> AuthenticateJwtToken(string token)
{
string username;
if (ValidateToken(token, out username))
{
// based on username to get more information from database
// in order to build local identity
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, username)
// Add more claims if needed: Roles, ...
};
var identity = new ClaimsIdentity(claims, "Jwt");
IPrincipal user = new ClaimsPrincipal(identity);
return Task.FromResult(user);
}
return Task.FromResult<IPrincipal>(null);
}
The workflow is to use the JWT library (NuGet package above) to validate the JWT token and then return back ClaimsPrincipal
. You can perform more validation, like check whether user exists on your system, and add other custom validations if you want.
The code to validate JWT token and get principal back:
public static ClaimsPrincipal GetPrincipal(string token)
{
try
{
var tokenHandler = new JwtSecurityTokenHandler();
var jwtToken = tokenHandler.ReadToken(token) as JwtSecurityToken;
if (jwtToken == null)
return null;
var symmetricKey = Convert.FromBase64String(Secret);
var validationParameters = new TokenValidationParameters()
{
RequireExpirationTime = true,
ValidateIssuer = false,
ValidateAudience = false,
IssuerSigningKey = new SymmetricSecurityKey(symmetricKey)
};
SecurityToken securityToken;
var principal = tokenHandler.ValidateToken(token, validationParameters, out securityToken);
return principal;
}
catch (Exception)
{
//should write log
return null;
}
}
If the JWT token is validated and the principal is returned, you should build a new local identity and put more information into it to check role authorization.
Remember to add config.Filters.Add(new AuthorizeAttribute());
(default authorization) at global scope in order to prevent any anonymous request to your resources.
You can use Postman to test the demo:
Request token (naive as I mentioned above, just for demo):
GET http://localhost:{port}/api/token?username=cuong&password=1
Put JWT token in the header for authorized request, example:
GET http://localhost:{port}/api/value
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1bmlxdWVfbmFtZSI6ImN1b25nIiwibmJmIjoxNDc3NTY1MjU4LCJleHAiOjE0Nzc1NjY0NTgsImlhdCI6MTQ3NzU2NTI1OH0.dSwwufd4-gztkLpttZsZ1255oEzpWCJkayR_4yvNL1s
The demo can be found here: https://github.com/cuongle/WebApi.Jwt
Modify your log4j.properties
file accordingly:
log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog
Change the log levels for each logger depending to your needs.
The Groovy way to do this is
def list = []
list << new MyType(...)
which creates a list and uses the overloaded leftShift
operator to append an item
See the Groovy docs on Lists for lots of examples.
You can just call a method on your scope to reverse it for you, like this:
<!doctype html>
<html ng-app="myApp">
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.angularjs.org/1.0.5/angular.min.js"></script>
<script>
angular.module('myApp', []).controller('Ctrl', function($scope) {
$scope.items = [1, 2, 3, 4];
$scope.reverse = function(array) {
var copy = [].concat(array);
return copy.reverse();
}
});
</script>
</head>
<body ng-controller="Ctrl">
<ul>
<li ng-repeat="item in items">{{item}}</li>
</ul>
<ul>
<li ng-repeat="item in reverse(items)">{{item}}</li>
</ul>
</body>
</html>
Note that the $scope.reverse
creates a copy of the array since Array.prototype.reverse
modifies the original array.
Finally I found solution myself.
I had to annotate enum with @JsonSerialize(using = OrderTypeSerializer.class)
and implement custom serializer:
public class OrderTypeSerializer extends JsonSerializer<OrderType> {
@Override
public void serialize(OrderType value, JsonGenerator generator,
SerializerProvider provider) throws IOException,
JsonProcessingException {
generator.writeStartObject();
generator.writeFieldName("id");
generator.writeNumber(value.getId());
generator.writeFieldName("name");
generator.writeString(value.getName());
generator.writeEndObject();
}
}
Filter
app.filter('unsafe', function($sce) { return $sce.trustAsHtml; });
Usage
<ANY ng-bind-html="value | unsafe"></ANY>
I think comboBox1.Items.Add("X");
will add string
to ComboBox, instead of ComboBoxItem
.
The right solution is
ComboBoxItem item = new ComboBoxItem();
item.Content = "A";
comboBox1.Items.Add(item);
Take a look from here https://www.regextester.com/?fam=114662
Use this following Regular Expression Details, This will support leap year also.
var reg = /^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(([1][26]|[2468][048]|[3579][26])00))))$/g;
if you got troubles with windows cmd command and .bat just escape percents like that
git show -s --format=%%ct
The % character has a special meaning for command line parameters and FOR parameters. To treat a percent as a regular character, double it: %%

I had trouble passing parameters to the Commands.AddScript method.
C:\Foo1.PS1 Hello World Hunger
C:\Foo2.PS1 Hello World
scriptFile = "C:\Foo1.PS1"
parameters = "parm1 parm2 parm3" ... variable length of params
I Resolved this by passing null
as the name and the param as value into a collection of CommandParameters
Here is my function:
private static void RunPowershellScript(string scriptFile, string scriptParameters)
{
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
Command scriptCommand = new Command(scriptFile);
Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
foreach (string scriptParameter in scriptParameters.Split(' '))
{
CommandParameter commandParm = new CommandParameter(null, scriptParameter);
commandParameters.Add(commandParm);
scriptCommand.Parameters.Add(commandParm);
}
pipeline.Commands.Add(scriptCommand);
Collection<PSObject> psObjects;
psObjects = pipeline.Invoke();
}
Try using document.getElementById("myForm")
instead of document.myForm.
<script>
var auto_refresh = setInterval(function() { submitform(); }, 10000);
function submitform()
{
alert('test');
document.getElementById("myForm").submit();
}
</script>
A quick google search yields kludgey solutions such as this that use setjmp/longjmp as others have mentioned. Nothing as straightforward and elegant as C++/Java's try/catch. I'm rather partial to Ada's exception handling myself.
Check everything with if statements :)
motivated by previous contributors, this is an example of three axes.

You can write complete apps for almost any smartphone platform (Android, iOS,...) using Phonegap. (http://www.phonegap.com)
It is an open source framework that exposes native capabilities to a web view, so that you can do anything a native app can do.
This is very suitable for cross platform development if you're not building something that has to be pixel perfect in every way, or is very hardware intensive.
If you are looking for UI Frameworks that can be used to build such apps, there is a wide range of different libraries. (Like Sencha, jQuery mobile, ...)
And to be a little biased, there is something I built as well: http://www.m-gwt.com
Select 4th option
$('#select').val($('#select option').eq(3).val());
In [9]: pd.Series(df.Letter.values,index=df.Position).to_dict()
Out[9]: {1: 'a', 2: 'b', 3: 'c', 4: 'd', 5: 'e'}
Speed comparion (using Wouter's method)
In [6]: df = pd.DataFrame(randint(0,10,10000).reshape(5000,2),columns=list('AB'))
In [7]: %timeit dict(zip(df.A,df.B))
1000 loops, best of 3: 1.27 ms per loop
In [8]: %timeit pd.Series(df.A.values,index=df.B).to_dict()
1000 loops, best of 3: 987 us per loop
The function below works perfectly for me:
// Note this *is* JQuery, see below for JS solution instead
function replaceText(selector, text, newText, flags) {
var matcher = new RegExp(text, flags);
$(selector).each(function () {
var $this = $(this);
if (!$this.children().length)
$this.text($this.text().replace(matcher, newText));
});
}
Here's a usage example:
function replaceAllText() {
replaceText('*', 'hello', 'hi', 'g');
}
$(document).ready(replaceAllText);
$('html').ajaxStop(replaceAllText);
You can also use do a direct replacement like so:
document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');
But be careful with it since it may affect the tags, css and scripts as well.
EDIT: As for a pure JavaScript solution use this method instead:
function replaceText(selector, text, newText, flags) {
var matcher = new RegExp(text, flags);
var elems = document.querySelectorAll(selector), i;
for (i = 0; i < elems.length; i++)
if (!elems[i].childNodes.length)
elems[i].innerHTML = elems[i].innerHTML.replace(matcher, newText);
}
You can use the following for an awk solution -
awk '/^#/ {sub(/#.*/,"");getline;}1' inputfile
You're already doing it!
save()
will check if something in the model has changed. If it hasn't it won't run a db query.
Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate
:
protected function performUpdate(Builder $query, array $options = [])
{
$dirty = $this->getDirty();
if (count($dirty) > 0)
{
// runs update query
}
return true;
}
The getDirty()
method simply compares the current attributes with a copy saved in original
when the model is created. This is done in the syncOriginal()
method:
public function __construct(array $attributes = array())
{
$this->bootIfNotBooted();
$this->syncOriginal();
$this->fill($attributes);
}
public function syncOriginal()
{
$this->original = $this->attributes;
return $this;
}
If you want to check if the model is dirty just call isDirty()
:
if($product->isDirty()){
// changes have been made
}
Or if you want to check a certain attribute:
if($product->isDirty('price')){
// price has changed
}
I had this error and found it was due to the presence an 'Import' XML tag inside the .csproj.user file. Once I removed it, Visual Studio could open the project again.
I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:
My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.
private void startCreation(){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
Uri startDir = Uri.fromFile(new File("/sdcard"));
intent.setDataAndType(startDir,
"vnd.android.cursor.dir/lysesoft.andexplorer.file");
intent.putExtra("browser_filter_extension_whitelist", "*.csv");
intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
intent.putExtra("browser_title_background_color",
getText(R.string.browser_title_background_color));
intent.putExtra("browser_title_foreground_color",
getText(R.string.browser_title_foreground_color));
intent.putExtra("browser_list_background_color",
getText(R.string.browser_list_background_color));
intent.putExtra("browser_list_fontscale", "120%");
intent.putExtra("browser_list_layout", "2");
try{
ApplicationInfo info = getPackageManager()
.getApplicationInfo("lysesoft.andexplorer", 0 );
startActivityForResult(intent, PICK_REQUEST_CODE);
} catch( PackageManager.NameNotFoundException e ){
showInstallResultMessage(R.string.error_install_andexplorer);
} catch (Exception e) {
Log.w(TAG, e.getMessage());
}
}
This methos is just pick up a dialog and if user wants install the external application from market
private void showInstallResultMessage(int msg_id) {
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setMessage(getText(msg_id));
dialog.setButton(getText(R.string.button_ok),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
dialog.setButton2(getText(R.string.button_install),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
startActivity(intent);
finish();
}
});
dialog.show();
}
You can try jstorage javascript plugin, it is an elegant way to maintain sessions check this http://www.jstorage.info/
include the jStorage.js script into your html
<script src="jStorage.js"></script>
Then in your javascript place the sessiontoken into the a key like this
$.jStorage.set("YOUR_KEY",session_id);
Where "YOUR_KEY" is the key using which you can access you session_id , like this:
var id = $.jStorage.get("YOUR_KEY");
If you're interested in producing HTML5 hybrid applications (web apps wrapped in a native container giving access to device functions), the Nomad Visual Studio extension supports building for android devices.
Years ago, I implemented the following hashtable, which has had some features that have been missing to the Map class. However, that's no longer the case. Now it's possible to iterate over the entries of a Map, get an array of its keys or values or both (these operations are implemented copying to a newly allocated array, though — that's a waste of memory and its time complexity will always be as bad as O(n)), remove specific items given their key, and clear the whole map. Therefore, my hashtable implementation is only useful for compatibility purposes, though in this case it would be more appropriate to write a proper polyfill. I'd suggest to anyone who would use my hashtable implementation to change it so to make it become a polyfill for the Map class.
function Hashtable() {
this._map = new Map();
this._indexes = new Map();
this._keys = [];
this._values = [];
this.put = function(key, value) {
var newKey = !this.containsKey(key);
this._map.set(key, value);
if (newKey) {
this._indexes.set(key, this.length);
this._keys.push(key);
this._values.push(value);
}
};
this.remove = function(key) {
if (!this.containsKey(key))
return;
this._map.delete(key);
var index = this._indexes.get(key);
this._indexes.delete(key);
this._keys.splice(index, 1);
this._values.splice(index, 1);
};
this.indexOfKey = function(key) {
return this._indexes.get(key);
};
this.indexOfValue = function(value) {
return this._values.indexOf(value) != -1;
};
this.get = function(key) {
return this._map.get(key);
};
this.entryAt = function(index) {
var item = {};
Object.defineProperty(item, "key", {
value: this.keys[index],
writable: false
});
Object.defineProperty(item, "value", {
value: this.values[index],
writable: false
});
return item;
};
this.clear = function() {
var length = this.length;
for (var i = 0; i < length; i++) {
var key = this.keys[i];
this._map.delete(key);
this._indexes.delete(key);
}
this._keys.splice(0, length);
};
this.containsKey = function(key) {
return this._map.has(key);
};
this.containsValue = function(value) {
return this._values.indexOf(value) != -1;
};
this.forEach = function(iterator) {
for (var i = 0; i < this.length; i++)
iterator(this.keys[i], this.values[i], i);
};
Object.defineProperty(this, "length", {
get: function() {
return this._keys.length;
}
});
Object.defineProperty(this, "keys", {
get: function() {
return this._keys;
}
});
Object.defineProperty(this, "values", {
get: function() {
return this._values;
}
});
Object.defineProperty(this, "entries", {
get: function() {
var entries = new Array(this.length);
for (var i = 0; i < entries.length; i++)
entries[i] = this.entryAt(i);
return entries;
}
});
}

There is nothing like Silver Bullet. Everything comes with some cost associated with it. It is like if you eat oily food, you will compromise your health and healthy food does not come with spices like oily food. It is individual choice whether they want health or spices as in their food. Same way Node.js consider to be used in specific scenario. If your app does not fit into that scenario you should not consider it for your app development. I am just putting my thought on the same:
When to use Node.JS
When NOT to use Node.JS
Scalability Consideration with Node.JS
Node.JS Alternatives
There are other option to use in place of Node.JS however Vert.x seems to be pretty promising and has lots of additional features like polygot and better scalability considerations.
It sounds like you're trying to use log4j from "both ends" (the consumer end and the configuration end).
If you want to code against the slf4j api but determine ahead of time (and programmatically) the configuration of the log4j Loggers that the classpath will return, you absolutely have to have some sort of logging adaptation which makes use of lazy construction.
public class YourLoggingWrapper {
private static boolean loggingIsInitialized = false;
public YourLoggingWrapper() {
// ...blah
}
public static void debug(String debugMsg) {
log(LogLevel.Debug, debugMsg);
}
// Same for all other log levels your want to handle.
// You mentioned TRACE and ERROR.
private static void log(LogLevel level, String logMsg) {
if(!loggingIsInitialized)
initLogging();
org.slf4j.Logger slf4jLogger = org.slf4j.LoggerFactory.getLogger("DebugLogger");
switch(level) {
case: Debug:
logger.debug(logMsg);
break;
default:
// whatever
}
}
// log4j logging is lazily constructed; it gets initialized
// the first time the invoking app calls a log method
private static void initLogging() {
loggingIsInitialized = true;
org.apache.log4j.Logger debugLogger = org.apache.log4j.LoggerFactory.getLogger("DebugLogger");
// Now all the same configuration code that @oers suggested applies...
// configure the logger, configure and add its appenders, etc.
debugLogger.addAppender(someConfiguredFileAppender);
}
With this approach, you don't need to worry about where/when your log4j loggers get configured. The first time the classpath asks for them, they get lazily constructed, passed back and made available via slf4j. Hope this helped!
You can use the following class. Just change zero to any default value you like. The solution was tested in Python 2.7.
class cDefaultDict(dict):
# dictionary that returns zero for missing keys
# keys with zero values are not stored
def __missing__(self,key):
return 0
def __setitem__(self, key, value):
if value==0:
if key in self: # returns zero anyway, so no need to store it
del self[key]
else:
dict.__setitem__(self, key, value)
First off I recommend you use the following constructor instead of the one you currently use:
new SerialPort("COM10", 115200, Parity.None, 8, StopBits.One);
Next, you really should remove this code:
// Wait 10 Seconds for data...
for (int i = 0; i < 1000; i++)
{
Thread.Sleep(10);
Console.WriteLine(sp.Read(buf,0,bufSize)); //prints data directly to the Console
}
And instead just loop until the user presses a key or something, like so:
namespace serialPortCollection
{ class Program
{
static void Main(string[] args)
{
SerialPort sp = new SerialPort("COM10", 115200);
sp.DataReceived += port_OnReceiveDatazz; // Add DataReceived Event Handler
sp.Open();
sp.WriteLine("$"); //Command to start Data Stream
Console.ReadLine();
sp.WriteLine("!"); //Stop Data Stream Command
sp.Close();
}
// My Event Handler Method
private static void port_OnReceiveDatazz(object sender,
SerialDataReceivedEventArgs e)
{
SerialPort spL = (SerialPort) sender;
byte[] buf = new byte[spL.BytesToRead];
Console.WriteLine("DATA RECEIVED!");
spL.Read(buf, 0, buf.Length);
foreach (Byte b in buf)
{
Console.Write(b.ToString());
}
Console.WriteLine();
}
}
}
Also, note the revisions to the data received event handler, it should actually print the buffer now.
UPDATE 1
I just ran the following code successfully on my machine (using a null modem cable between COM33 and COM34)
namespace TestApp
{
class Program
{
static void Main(string[] args)
{
Thread writeThread = new Thread(new ThreadStart(WriteThread));
SerialPort sp = new SerialPort("COM33", 115200, Parity.None, 8, StopBits.One);
sp.DataReceived += port_OnReceiveDatazz; // Add DataReceived Event Handler
sp.Open();
sp.WriteLine("$"); //Command to start Data Stream
writeThread.Start();
Console.ReadLine();
sp.WriteLine("!"); //Stop Data Stream Command
sp.Close();
}
private static void port_OnReceiveDatazz(object sender,
SerialDataReceivedEventArgs e)
{
SerialPort spL = (SerialPort) sender;
byte[] buf = new byte[spL.BytesToRead];
Console.WriteLine("DATA RECEIVED!");
spL.Read(buf, 0, buf.Length);
foreach (Byte b in buf)
{
Console.Write(b.ToString() + " ");
}
Console.WriteLine();
}
private static void WriteThread()
{
SerialPort sp2 = new SerialPort("COM34", 115200, Parity.None, 8, StopBits.One);
sp2.Open();
byte[] buf = new byte[100];
for (byte i = 0; i < 100; i++)
{
buf[i] = i;
}
sp2.Write(buf, 0, buf.Length);
sp2.Close();
}
}
}
UPDATE 2
Given all of the traffic on this question recently. I'm beginning to suspect that either your serial port is not configured properly, or that the device is not responding.
I highly recommend you attempt to communicate with the device using some other means (I use hyperterminal frequently). You can then play around with all of these settings (bitrate, parity, data bits, stop bits, flow control) until you find the set that works. The documentation for the device should also specify these settings. Once I figured those out, I would make sure my .NET SerialPort is configured properly to use those settings.
Some tips on configuring the serial port:
Note that when I said you should use the following constructor, I meant that use that function, not necessarily those parameters! You should fill in the parameters for your device, the settings below are common, but may be different for your device.
new SerialPort("COM10", 115200, Parity.None, 8, StopBits.One);
It is also important that you setup the .NET SerialPort to use the same flow control as your device (as other people have stated earlier). You can find more info here:
http://www.lammertbies.nl/comm/info/RS-232_flow_control.html
Guava Converters do the trick.
import com.google.common.base.Splitter;
import com.google.common.primitives.Longs;
final Iterable<Long> longIds =
Longs.stringConverter().convertAll(
Splitter.on(',').trimResults().omitEmptyStrings()
.splitToList("1,2,3"));
My solution is Change the text inputs type dynamically using angular js directive and it works like charm
first add 2 hidden text fields
and just add a angular directive like this
(function () {
'use strict';
appname.directive('changePasswordType', directive);
directive.$inject = ['$timeout', '$rootScope', '$cookies'];
function directive($timeout, $rootScope, $cookies) {
var directive = {
link: link,
restrict: 'A'
};
return directive;
function link(scope,element) {
var process = function () {
var elem =element[0];
elem.value.length > 0 ? element[0].setAttribute("type", "password") :
element[0].setAttribute("type", "text");
}
element.bind('input', function () {
process();
});
element.bind('keyup', function () {
process();
});
}
}
})()
then use it in your text field where you need to prevent auto complete
<input type="text" style="display:none">\\can avoid this 2 lines
<input type="password" style="display:none">
<input type="text" autocomplete="new-password" change-password-type>
NB: dont forget to include jquery, and set type ="text"
initially
The problem occurs because webpack-dev-server
2.4.4 adds a host check. You can disable it by adding this to your webpack config:
devServer: {
compress: true,
disableHostCheck: true, // That solved it
}
EDIT: Please note, this fix is insecure.
Please see the following answer for a secure solution: https://stackoverflow.com/a/43621275/5425585
\n
is a line feed (LF) character, character code 10. \r
is a carriage return (CR) character, character code 13. What they do differs from system to system. On Windows, for instance, lines in text files are terminated using CR followed immediately by LF (e.g., CRLF). On Unix systems and their derivatives, only LF is used. (Macs prior to Mac OS X used CR, but Mac OS X is a *nix derivative and so uses LF.)
In the old days, LF literally did just a line feed on printers (moving down one line without moving where you are horizonally on the page), and CR similarly moved back to the beginning of the line without moving the paper up, hence some systems (like Windows) sending CR (return to the left-hand side) and LF (and feed the paper up).
Because of all this confusion, some output targets will accept multiple line break sequences, so you could see the same effect from either character depending on what you're outputting to.
If you use form.close() in your form and set the FormClosing Event of your form and either use form.close() in this Event ,you fall in unlimited loop and Argument out of range happened and the solution is that change the form.close() with form.dispose() in Event of FormClosing. I hope this little tip help you!!!
If you're using django, you can use urlquote:
>>> from django.utils.http import urlquote
>>> urlquote(u"Müller")
u'M%C3%BCller'
Note that changes to Python since this answer was published mean that this is now a legacy wrapper. From the Django 2.1 source code for django.utils.http:
A legacy compatibility wrapper to Python's urllib.parse.quote() function.

based on @CanalDoMestre's answer. I added support for the blank filter case, fixed a typo and prevented hiding the rows so I can still see the column headers.
$("#filterby").on('keyup', function() {
if (this.value.length < 1) {
$("#list tr").css("display", "");
} else {
$("#list tbody tr:not(:contains('"+this.value+"'))").css("display", "none");
$("#list tbody tr:contains('"+this.value+"')").css("display", "");
}
});
Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.
javascript:location.href=%22googlechrome%22+location.href.substring(4);
Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.
Works for me.
You can simplify it like this:
if ( that_happened || something_else_happened )
{
header('X-Error-Message: Incorrect username or password', true, 500);
die;
}
It will return following header:
HTTP/1.1 500 Internal Server Error
...
X-Error-Message: Incorrect username or password
...
Added: If you need to know exactly what went wrong, do something like this:
if ( that_happened )
{
header('X-Error-Message: Incorrect username', true, 500);
die('Incorrect username');
}
if ( something_else_happened )
{
header('X-Error-Message: Incorrect password', true, 500);
die('Incorrect password');
}
There is indeed a fancy shmancy native function in java you should leverage.
ArrayList has an instance method called
indexOf(Object o)
(http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html)
You would be able to call it on _categories
as follows:
_categories.indexOf("camels")
I have no experience with programming for Android - but this would work for a standard Java application.
Good luck.
$('#myinput').is(':checkbox')
this is the only work, to solve the issue to detect if checkbox checked or not. It returns true or false, I search it for hours and try everything, now its work to be clear I use EDG as browser and W2UI
I followed @Viktor Kerkez's answer and have had mixed success. I found that sometimes this recipe of
conda skeleton pypi PACKAGE
conda build PACKAGE
would look like everything worked but I could not successfully import PACKAGE. Recently I asked about this on the Anaconda user group and heard from @Travis Oliphant himself on the best way to use conda to build and manage packages that do not ship with Anaconda. You can read this thread here, but I'll describe the approach below to hopefully make the answers to the OP's question more complete...
Example: I am going to install the excellent prettyplotlib package on Windows using conda 2.2.5.
1a) conda build --build-recipe prettyplotlib
You'll see the build messages all look good until the final TEST section of the build. I saw this error
File "C:\Anaconda\conda-bld\test-tmp_dir\run_test.py", line 23 import None SyntaxError: cannot assign to None TESTS FAILED: prettyplotlib-0.1.3-py27_0
1b) Go into /conda-recipes/prettyplotlib and edit the meta.yaml file. Presently, the packages being set up like in step 1a result in yaml files that have an error in the test
section. For example, here is how mine looked for prettyplotlib
test: # Python imports imports:
-
- prettyplotlib
- prettyplotlib
Edit this section to remove the blank line preceded by the - and also remove the redundant prettyplotlib line. At the time of this writing I have found that I need to edit most meta.yaml files like this for external packages I am installing with conda, meaning that there is a blank import line causing the error along with a redundant import of the given package.
1c) Rerun the command from 1a, which should complete with out error this time. At the end of the build you'll be asked if you want to upload the build to binstar. I entered No and then saw this message:
If you want to upload this package to binstar.org later, type:
$ binstar upload C:\Anaconda\conda-bld\win-64\prettyplotlib-0.1.3-py27_0.tar.bz2
That tar.bz2 file is the build that you now need to actually install.
2) conda install C:\Anaconda\conda-bld\win-64\prettyplotlib-0.1.3-py27_0.tar.bz2
Following these steps I have successfully used conda to install a number of packages that do not come with Anaconda. Previously, I had installed some of these using pip, so I did pip uninstall PACKAGE
prior to installing PACKAGE with conda. Using conda, I can now manage (almost) all of my packages with a single approach rather than having a mix of stuff installed with conda, pip, easy_install, and python setup.py install.
For context, I think this recent blog post by @Travis Oliphant will be helpful for people like me who do not appreciate everything that goes into robust Python packaging but certainly appreciate when stuff "just works". conda seems like a great way forward...
In JavaScript there are two ways to create functions:
Function declaration:
function fn(){
console.log("Hello");
}
fn();
This is very basic, self-explanatory, used in many languages and standard across C family of languages. We declared a function defined it and executed it by calling it.
What you should be knowing is that functions are actually objects in JavaScript; internally we have created an object for above function and given it a name called fn or the reference to the object is stored in fn. Functions are objects in JavaScript; an instance of function is actually an object instance.
Function expression:
var fn=function(){
console.log("Hello");
}
fn();
JavaScript has first-class functions, that is, create a function and assign it to a variable just like you create a string or number and assign it to a variable. Here, the fn variable is assigned to a function. The reason for this concept is functions are objects in JavaScript; fn is pointing to the object instance of the above function. We have initialized a function and assigned it to a variable. It's not executing the function and assigning the result.
Reference: JavaScript function declaration syntax: var fn = function() {} vs function fn() {}
Extending answer of @MichaelLaCroix when a scenario is that the components can't communicate between any sort of parent-child relationship, the documentation recommends setting up a global event system.
In the case of <Filters />
and <TopBar />
don't have any of the above relationship, a simple global emitter could be used like this:
componentDidMount
- Subscribe to event
componentWillUnmount
- Unsubscribe from event
EventSystem.js
class EventSystem{
constructor() {
this.queue = {};
this.maxNamespaceSize = 50;
}
publish(/** namespace **/ /** arguments **/) {
if(arguments.length < 1) {
throw "Invalid namespace to publish";
}
var namespace = arguments[0];
var queue = this.queue[namespace];
if (typeof queue === 'undefined' || queue.length < 1) {
console.log('did not find queue for %s', namespace);
return false;
}
var valueArgs = Array.prototype.slice.call(arguments);
valueArgs.shift(); // remove namespace value from value args
queue.forEach(function(callback) {
callback.apply(null, valueArgs);
});
return true;
}
subscribe(/** namespace **/ /** callback **/) {
const namespace = arguments[0];
if(!namespace) throw "Invalid namespace";
const callback = arguments[arguments.length - 1];
if(typeof callback !== 'function') throw "Invalid callback method";
if (typeof this.queue[namespace] === 'undefined') {
this.queue[namespace] = [];
}
const queue = this.queue[namespace];
if(queue.length === this.maxNamespaceSize) {
console.warn('Shifting first element in queue: `%s` since it reached max namespace queue count : %d', namespace, this.maxNamespaceSize);
queue.shift();
}
// Check if this callback already exists for this namespace
for(var i = 0; i < queue.length; i++) {
if(queue[i] === callback) {
throw ("The exact same callback exists on this namespace: " + namespace);
}
}
this.queue[namespace].push(callback);
return [namespace, callback];
}
unsubscribe(/** array or topic, method **/) {
let namespace;
let callback;
if(arguments.length === 1) {
let arg = arguments[0];
if(!arg || !Array.isArray(arg)) throw "Unsubscribe argument must be an array";
namespace = arg[0];
callback = arg[1];
}
else if(arguments.length === 2) {
namespace = arguments[0];
callback = arguments[1];
}
if(!namespace || typeof callback !== 'function') throw "Namespace must exist or callback must be a function";
const queue = this.queue[namespace];
if(queue) {
for(var i = 0; i < queue.length; i++) {
if(queue[i] === callback) {
queue.splice(i, 1); // only unique callbacks can be pushed to same namespace queue
return;
}
}
}
}
setNamespaceSize(size) {
if(!this.isNumber(size)) throw "Queue size must be a number";
this.maxNamespaceSize = size;
return true;
}
isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
}
NotificationComponent.js
class NotificationComponent extends React.Component {
getInitialState() {
return {
// optional. see alternative below
subscriber: null
};
}
errorHandler() {
const topic = arguments[0];
const label = arguments[1];
console.log('Topic %s label %s', topic, label);
}
componentDidMount() {
var subscriber = EventSystem.subscribe('error.http', this.errorHandler);
this.state.subscriber = subscriber;
}
componentWillUnmount() {
EventSystem.unsubscribe('error.http', this.errorHandler);
// alternatively
// EventSystem.unsubscribe(this.state.subscriber);
}
render() {
}
}
Another solution (poor one do) is exiting VM Box with saving desktop (top option), restart would bring back the screen as it was before the rescale.
You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.
You need to compare, not assign:
if (strcmp("hello", "hello") == 0)
^
Because you want to check if the result of strcmp("hello", "hello")
equals to 0
.
About the error:
lvalue required as left operand of assignment
lvalue
means an assignable value (variable), and in assignment the left value to the =
has to be lvalue
(pretty clear).
Both function results and constants are not assignable (rvalue
s), so they are rvalue
s. so the order doesn't matter and if you forget to use ==
you will get this error. (edit:)I consider it a good practice in comparison to put the constant in the left side, so if you write =
instead of ==
, you will get a compilation error. for example:
int a = 5;
if (a = 0) // Always evaluated as false, no error.
{
//...
}
vs.
int a = 5;
if (0 = a) // Generates compilation error, you cannot assign a to 0 (rvalue)
{
//...
}

I guess your code relates to Windows Forms.
You call BeginInvoke
if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)
If BeginInvoke
is called for Delegate
type the delegate is just invoked asynchronously.
(Invoke
for the sync version.)
If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task
with the according context. (TaskScheduler.FromCurrentSynchronizationContext()
)
And to add a little to already said by others:
Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var
with lambdas: compiler needs a hint.
UPDATE:
this requires .Net v4.0 and higher
// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();
// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);
// also can be called anywhere. Task will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked)
task.Start(scheduler);
If you started the task from other thread and need to wait for its completition task.Wait()
will block calling thread till the end of the task.
Read more about tasks here.
In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]
Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.
If your iPhone is jailbroken you can use DemoGod
if (!$(row).hasClass("changed")) {
// do your stuff
}
Try wrapping your dates in single quotes, like this:
'15-6-2005'
It should be able to parse the date this way.
It will be proxy configuration of your browser.
In NetWork Setting, use no proxy
For Manual proxy configuration
add exception(No Proxy for in Firefox) like localhost:8080, localhost
.
If you google for javascript callback function example
you will get Getting a better understanding of callback functions in JavaScript
This is how to do a callback function:
function f() {
alert('f was called!');
}
function callFunction(func) {
func();
}
callFunction(f);
Since dates correspond to a numeric value and a starting date, you indeed need the day. If you really need your data to be in Date format, you can just fix the day to the first of each month manually by pasting it to the date:
month <- "2009-03"
as.Date(paste(month,"-01",sep=""))
I received this error because I had recently created a new workspace and my "Installed JREs" were not set up correctly. Make sure in Preferences -> Java -> Installed JREs
the root folder of your JDK is selected. The default for me in a new workspace was a JRE for some reason.
I know this is old but just to pitch in my experience. I just ran into it this morning. Turns our my error has nothing to do with .xls line limit or array index. It is caused by an incorrect formula.
I was exporting from database to Excel a sheet about my customers. Someone fill in the customer name as =90Erickson-King
and apparently this is fine as a string-type field in the database, however will result in an error as a formula in Excel. Instead of showing #N/A
like when you're using Excel, the program just froze and spilt that 0x800A03EC error a while later.
I corrected this by deleting the equal sign and the dash in the customer's name. After that exporting went well.
I guess this error code is a bit too general as people are seen reporting quite a range of different possible causes.
If you have multiple ports to allow in Centos 7 FIrewalld then we can use the following command.
#firewall-cmd --add-port={port number/tcp,port number/tcp} --permanent
#firewall-cmd --reload
And check the Port opened or not after reloading the firewall.
#firewall-cmd --list-port

I ran into this problem as well. The underlying problem is that the ssl library in Python 2.7 versions < 2.7.9 is no longer compatible with the pip mechanism.
If you are running on Windows, and you (like us) can't easily upgrade from an incompatible version of 2.7, FWIW, I found that if you copy the following files from another install of the latest version of Python (e.g. Python 2.7.15) on another machine to your installation:
Lib\ssl.py
libs\_ssl.lib
DLLs\_ssl.dll
it will effectively "upgrade" your SSL layer to one which is supported; we were then be able to use pip again, even to upgrade pip.
In Spring Util, there is a better way..,
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.util.concurrent.ListenableFuture;
import org.springframework.web.util.UriComponents;
import org.springframework.web.util.UriComponentsBuilder;
MultiValueMap<String, String> params = new LinkedMultiValueMap<String, String>();
params.add("key", key);
params.add("storeId", storeId);
params.add("orderId", orderId);
UriComponents uriComponents = UriComponentsBuilder.fromHttpUrl("http://spsenthil.com/order").queryParams(params).build();
ListenableFuture<ResponseEntity<String>> responseFuture = restTemplate.getForEntity(uriComponents.toUriString(), String.class);
Generally you can do
select * from your_table
order by case when name = 'core' then 1 else 2 end,
priority
Especially in MySQL you can also do
select * from your_table
order by name <> 'core',
priority
Since the result of a comparision in MySQL is either 0
or 1
and you can sort by that result.
Assume if all the input elements are inside a form u can refer the below code.
// get all the inputs into an array.
var $inputs = $('#myForm :input');
// not sure if you wanted this, but I thought I'd add it.
// get an associative array of just the values.
var values = {};
$inputs.each(function() {
values[this.name] = $(this).val();
});
use the fully qualified name instead of importing the class.
e.g.
//import java.util.Date; //delete this
//import my.own.Date;
class Test{
public static void main(String [] args){
// I want to choose my.own.Date here. How?
my.own.Date myDate = new my.own.Date();
// I want to choose util.Date here. How ?
java.util.Date javaDate = new java.util.Date();
}
}
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
And also ng update @angular/material
will update your code and fix all imports
You can use the out
contextual keyword in two contexts (each is a link to detailed information), as a parameter modifier or in generic type parameter declarations in interfaces and delegates. This topic discusses the parameter modifier, but you can see this other topic for information on the generic type parameter declarations.
The out
keyword causes arguments to be passed by reference. This is like the ref
keyword, except that ref
requires that the variable be initialized before it is passed. To use an out
parameter, both the method definition and the calling method must explicitly use the out
keyword. For example:
C#
class OutExample
{
static void Method(out int i)
{
i = 44;
}
static void Main()
{
int value;
Method(out value);
// value is now 44
}
}
Although variables passed as out
arguments do not have to be initialized before being passed, the called method is required to assign a value before the method returns.
Although the ref
and out
keywords cause different run-time behavior, they are not considered part of the method signature at compile time. Therefore, methods cannot be overloaded if the only difference is that one method takes a ref
argument and the other takes an out
argument. The following code, for example, will not compile:
C#
class CS0663_Example
{
// Compiler error CS0663: "Cannot define overloaded
// methods that differ only on ref and out".
public void SampleMethod(out int i) { }
public void SampleMethod(ref int i) { }
}
Overloading can be done, however, if one method takes a ref
or out
argument and the other uses neither, like this:
C#
class OutOverloadExample
{
public void SampleMethod(int i) { }
public void SampleMethod(out int i) { i = 5; }
}
Properties are not variables and therefore cannot be passed as out
parameters.
For information about passing arrays, see Passing Arrays Using ref
and out
(C# Programming Guide).
You can't use the ref
and out
keywords for the following kinds of methods:
Async methods, which you define by using the async modifier.
Iterator methods, which include a yield return or yield break statement.
Example
Declaring an out
method is useful when you want a method to return multiple values. The following example uses out
to return three variables with a single method call. Note that the third argument is assigned to null. This enables methods to return values optionally.
C#
class OutReturnExample
{
static void Method(out int i, out string s1, out string s2)
{
i = 44;
s1 = "I've been returned";
s2 = null;
}
static void Main()
{
int value;
string str1, str2;
Method(out value, out str1, out str2);
// value is now 44
// str1 is now "I've been returned"
// str2 is (still) null;
}
}

I have found that the following works well in 2.7.x
import os
two_up = os.path.normpath(os.path.join(__file__,'../'))
you can put
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
at the top of your car.js file for it to work, or you can do what Raynos said to do.
To answer your extra question
:
You can set which rows should be repeated on every page using:
$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);
Now, row 1, 2, 3, 4 and 5 will be repeated.

I would like to make a addon for tiago's answer:
Suppose you're hiding element using ng-show
and adding a required
attribute on the same:
<div ng-show="false">
<input required name="something" ng-model="name"/>
</div>
will throw an error something like :
An invalid form control with name='' is not focusable
This is because you just cannot impose required
validation on hidden
elements. Using ng-required
makes it easier to conditionally apply required validation which is just awesome!!
if you are getting this exception again and again then download my-sql connector and paste in tomcat/WEB-INF/lib folder...note that some times WEB-INF folder does not contains lib folder, at that time manually create lib folder and paste mysql connector in that folder..definitely this will work.if still you got problem then check that your jdk must match your system. i.e if your system is 64 bit then jdk must be 64 bit
Example for Continue:
number = 0
for number in range(10):
number = number + 1
if number == 5:
continue # continue here
print('Number is ' + str(number))
print('Out of loop')
Output:
Number is 1
Number is 2
Number is 3
Number is 4
Number is 6 # Note: 5 is skipped!!
Number is 7
Number is 8
Number is 9
Number is 10
Out of loop
The reason this doesn't work is that when you call String(md.digest(convertme))
, you are telling Java to interpret a sequence of encrypted bytes as a String. What you want is to convert the bytes into hexadecimal characters.
To easily apply the comm command to unsorted files, use Bash's process substitution:
$ bash --version
GNU bash, version 3.2.51(1)-release
Copyright (C) 2007 Free Software Foundation, Inc.
$ cat > abc
123
567
132
$ cat > def
132
777
321
So the files abc and def have one line in common, the one with "132". Using comm on unsorted files:
$ comm abc def
123
132
567
132
777
321
$ comm -12 abc def # No output! The common line is not found
$
The last line produced no output, the common line was not discovered.
Now use comm on sorted files, sorting the files with process substitution:
$ comm <( sort abc ) <( sort def )
123
132
321
567
777
$ comm -12 <( sort abc ) <( sort def )
132
Now we got the 132 line!
C++20 will add constexpr
strings and vectors
The following proposal has been accepted apparently: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0980r0.pdf and it adds constructors such as:
// 20.3.2.2, construct/copy/destroy
constexpr
basic_string() noexcept(noexcept(Allocator())) : basic_string(Allocator()) { }
constexpr
explicit basic_string(const Allocator& a) noexcept;
constexpr
basic_string(const basic_string& str);
constexpr
basic_string(basic_string&& str) noexcept;
in addition to constexpr versions of all / most methods.
There is no support as of GCC 9.1.0, the following fails to compile:
#include <string>
int main() {
constexpr std::string s("abc");
}
with:
g++-9 -std=c++2a main.cpp
with error:
error: the type ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} of ‘constexpr’ variable ‘s’ is not literal
std::vector

2019 Update
The Chrome display bug is still unfixed and though no fault of the patrons, none of the suggestions offered in the entirety of this website help to resolve the issue. I can concur that I have tried every single one of them in vain: only 1 comes close and that's the css rule: filter:blur(0); which eliminates the shifting of a container by 1px but does not resolve the blurred display bug of the container itself and any content it may have.
Here's the reality: there literally is no fix to this problem so here is a work around for fluid websites
CASE
I'm currently developing a fluid website and have 3 divs, all centered with hover effects and sharing percentage values in both the width and position. The Chrome bug occurs on the center container which is set to left:50%; and transform:translateX(-50%); a common setting.
EXAMPLE: First the HTML...
<div id="box1" class="box">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry"s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
</div>
<div id="box2" class="box">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry"s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
</div>
<div id="box3" class="box">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry"s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
</div>
Here's the CSS where the Chrome bug occurs...
*{margin:0; padding:0; border:0; outline:0; box-sizing:border-box; background:#505050;}
.box {position:absolute; border:1px solid #fff; border-radius:10px; width:26%; background:#8e1515; padding:25px; top:20px; font-size:12pt; color:#fff; overflow:hidden; text-align:center; transition:0.5s ease-in-out;}
.box:hover {background:#191616;}
.box:active {background:#191616;}
.box:focus {background:#191616;}
#box1 {left:5%;}
#box2 {left:50%; transform:translateX(-50%);} /* Bugged */
#box3 {right:5%;}
Here's the fixed css...
*{margin:0; padding:0; border:0; outline:0; box-sizing:border-box; background:#505050;}
.box {position:absolute; border:1px solid #fff; border-radius:10px; width:26%; background:#8e1515; padding:25px; top:20px; font-size:12pt; color:#fff; overflow:hidden; text-align:center; transition:0.5s ease-in-out;}
.box:hover {background:#191616;}
.box:active {background:#191616;}
.box:focus {background:#191616;}
#box1 {left:5%;}
#box2 {left:37%;} /* Fixed */
#box3 {right:5%;}

Fixed fiddle: https://jsfiddle.net/uoc6e2dm/2/
As you can see a small amount of tweaking to the CSS should reduce or eliminate the requirement to use transform for positioning. This could also apply to fixed width websites as well as fluid.
Assuming your div has some CSS classes already...
<div id="classMe" CssClass="first"></div>
The following won't replace existing definitions:
ClassMe.CssClass += " second";
And if you are not sure until the very last moment...
string classes = ClassMe.CssClass;
ClassMe.CssClass += (classes == "") ? "second" : " second";
I had the same problem yet. After comparing several modules that seem to have this feature, I decided to do it myself, it's simpler than I thought.
gist: https://gist.github.com/deemstone/8279565
var fetchBlock = lineByline(filepath, onEnd);
fetchBlock(function(lines, start){ ... }); //lines{array} start{int} lines[0] No.
It cover the file opened in a closure, that fetchBlock()
returned will fetch a block from the file, end split to array (will deal the segment from last fetch).
I've set the block size to 1024 for each read operation. This may have bugs, but code logic is obvious, try it yourself.
EF 4.7 actually gives a hint when you run Enable-migrations at multiple context.
More than one context type was found in the assembly 'Service.Domain'.
To enable migrations for 'Service.Domain.DatabaseContext.Context1',
use Enable-Migrations -ContextTypeName Service.Domain.DatabaseContext.Context1.
To enable migrations for 'Service.Domain.DatabaseContext.Context2',
use Enable-Migrations -ContextTypeName Service.Domain.DatabaseContext.Context2.

For a more cross-browser solution you could style all inputs the way you want the non-typed, text, and password then another style the overrides that style for radios, checkboxes, etc.
input { border:solid 1px red; }
input[type=radio],
input[type=checkbox],
input[type=submit],
input[type=reset],
input[type=file]
{ border:none; }
- Or -
could whatever part of your code that is generating the non-typed inputs give them a class like .no-type
or simply not output at all? Additionally this type of selection could be done with jQuery.
Did you include "Management Tools" as a chosen option during setup?
Ensure this option is selected, and SQL Server Management Studio will be installed on the machine.
Not automatically, no. You can create a project template as BlueWandered suggested or create a custom property sheet that you can use for your current and all future projects.
_CRT_SECURE_NO_WARNINGS
.Now any time you create a new project, add this property sheet like so...
The benefit here is that not only do you get a single place to manage common settings but anytime you change the settings they get propagated to ALL projects that use it. This is handy if you have a lot of settings like _CRT_SECURE_NO_WARNINGS
or libraries like Boost that you want to use in your projects.
Forking creates an entirely new repository from existing repository (simply doing git clone on gitHub/bitbucket)
Forks are best used: when the intent of the ‘split’ is to create a logically independent project, which may never reunite with its parent.
Branch strategy creates a new branch over the existing/working repository
Branches are best used: when they are created as temporary places to work through a feature, with the intent to merge the branch with the origin.
More Specific :- In open source projects it is the owner of the repository who decides who can push to the repository. However, the idea of open source is that everybody can contribute to the project.
This problem is solved by forks: any time a developer wants to change something in an open source project, they don’t clone the official repository directly. Instead, they fork it to create a copy. When the work is finished, they make a pull request so that the owner of the repository can review the changes and decide whether to merge them to his project.
At its core forking is similar to feature branching, but instead of creating branches a fork of the repository is made, and instead of doing a merge request you create a pull request.
The below links provide the difference in a well-explained manner :

You can also use Js2Py which is written in pure python and is able to both execute and translate javascript to python. Supports virtually whole JavaScript even labels, getters, setters and other rarely used features.
import js2py
js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
}
escramble_758()
""".replace("document.write", "return ")
result = js2py.eval_js(js) # executing JavaScript and converting the result to python string
Advantages of Js2Py include portability and extremely easy integration with python (since basically JavaScript is being translated to python).
To install:
pip install js2py
All the validation from model are skipped when we use validate: false
user = User.new(....)
user.save(validate: false)
You could try this to dynamically remove an object from an array without looping through it? Where e and t are just random objects.
>>> e = {'b':1, 'w': 2}
>>> t = {'b':1, 'w': 3}
>>> p = [e,t]
>>> p
[{'b': 1, 'w': 2}, {'b': 1, 'w': 3}]
>>>
>>> p.pop(p.index({'b':1, 'w': 3}))
{'b': 1, 'w': 3}
>>> p
[{'b': 1, 'w': 2}]
>>>
Do you really need to load it from a file? If you place it along your classes (in WEB-INF/classes) you can get an InputStream to it using the class loader:
InputStream csv =
SomeClassInTheSamePackage.class.getResourceAsStream("filename.csv");
You need to do it through an ArrayAdapter
which will adapt your ArrayList (or any other collection) to your items in your layout (ListView, Spinner etc.).
This is what the Android developer guide says:
A
ListAdapter
that manages aListView
backed by an array of arbitrary objects. By default this class expects that the provided resource id references a singleTextView
. If you want to use a more complex layout, use the constructors that also takes a field id. That field id should reference aTextView
in the larger layout resource.However the
TextView
is referenced, it will be filled with thetoString()
of each object in the array. You can add lists or arrays of custom objects. Override thetoString()
method of your objects to determine what text will be displayed for the item in the list.To use something other than
TextViews
for the array display, for instanceImageViews
, or to have some of data besidestoString()
results fill the views, overridegetView(int, View, ViewGroup)
to return the type of view you want.
So your code should look like:
public class YourActivity extends Activity {
private ListView lv;
public void onCreate(Bundle saveInstanceState) {
setContentView(R.layout.your_layout);
lv = (ListView) findViewById(R.id.your_list_view_id);
// Instanciating an array list (you don't need to do this,
// you already have yours).
List<String> your_array_list = new ArrayList<String>();
your_array_list.add("foo");
your_array_list.add("bar");
// This is the array adapter, it takes the context of the activity as a
// first parameter, the type of list view as a second parameter and your
// array as a third parameter.
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
your_array_list );
lv.setAdapter(arrayAdapter);
}
}
Make a string criteria to search for, like this:
string searchExpression = "ID = 5"
Then use the .Select()
method of the DataTable
object, like this:
DataRow[] foundRows = YourDataTable.Select(searchExpression);
Now you can loop through the results, like this:
int numberOfCalls;
bool result;
foreach(DataRow dr in foundRows)
{
// Get value of Calls here
result = Int32.TryParse(dr["Calls"], out numberOfCalls);
// Optionally, you can check the result of the attempted try parse here
// and do something if you wish
if(result)
{
// Try parse to 32-bit integer worked
}
else
{
// Try parse to 32-bit integer failed
}
}
You can convert your Delete method as POST as;
[HttpPost]
public void Delete(YourDomainModel itemToDelete)
{
}
The chosen solution works, however they also snap the background to the top scrolling position. I extended the code above to fix that 'jump'.
//Set 2 global variables
var scrollTopPosition = 0;
var lastKnownScrollTopPosition = 0;
//when the document loads
$(document).ready(function(){
//this only runs on the right platform -- this step is not necessary, it should work on all platforms
if( navigator.userAgent.match(/iPhone|iPad|iPod/i) ) {
//There is some css below that applies here
$('body').addClass('platform-ios');
//As you scroll, record the scrolltop position in global variable
$(window).scroll(function () {
scrollTopPosition = $(document).scrollTop();
});
//when the modal displays, set the top of the (now fixed position) body to force it to the stay in the same place
$('.modal').on('show.bs.modal', function () {
//scroll position is position, but top is negative
$('body').css('top', (scrollTopPosition * -1));
//save this number for later
lastKnownScrollTopPosition = scrollTopPosition;
});
//on modal hide
$('.modal').on('hidden.bs.modal', function () {
//force scroll the body back down to the right spot (you cannot just use scrollTopPosition, because it gets set to zero when the position of the body is changed by bootstrap
$('body').scrollTop(lastKnownScrollTopPosition);
});
}
});
The css is pretty simple:
// You probably already have this, but just in case you don't
body.modal-open {
overflow: hidden;
width: 100%;
height: 100%;
}
//only on this platform does it need to be fixed as well
body.platform-ios.modal-open {
position: fixed;
}
Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.
strProjectName = "Sheet1"
Cells(1, 1).Formula = "=" & strProjectName & "!" & Cells(2, 7).Address
The workbook and worksheet that strProjectName
references must exist at the time that this formula is placed. Excel will immediately try to evaluate the formula. You might be able to stop that from happening by turning off automatic recalculation until the workbook does exist.
for (int i = 0; i < 5; i++){
int asciiVal = rand()%26 + 97;
char asciiChar = asciiVal;
cout << asciiChar << " and ";
}
To understanding the concept, Inversion of Control (IoC) or Dependency Inversion Principle (DIP) involves two activities: abstraction, and inversion. Dependency Injection (DI) is just one of the few of the inversion methods.
To read more about this you can read my blog Here
It is a practice where you let the actual behavior come from outside of the boundary (Class in Object Oriented Programming). The boundary entity only knows the abstraction (e.g interface, abstract class, delegate in Object Oriented Programming) of it.
In term of programming, IoC try to solve monolithic code by making it modular, decoupling various parts of it, and make it unit-testable.
It is appropriate most of the time, unless you have situation where you just want monolithic code (e.g very simple program)
Yes, you can use the CSS feature named @font-face. It has only been officially approved in CSS3, but been proposed and implemented in CSS2 and has been supported in IE for quite a long time.
You declare it in the CSS like this:
@font-face { font-family: Delicious; src: url('Delicious-Roman.otf'); }
@font-face { font-family: Delicious; font-weight: bold; src: url('Delicious-Bold.otf');}
Then, you can just reference it like the other standard fonts:
h3 { font-family: Delicious, sans-serif; }
So, in this case,
<html>
<head>
<style>
@font-face { font-family: JuneBug; src: url('JUNEBUG.TTF'); }
h1 {
font-family: JuneBug
}
</style>
</head>
<body>
<h1>Hey, June</h1>
</body>
</html>
And you just need to put the JUNEBUG.TFF in the same location as the html file.
I downloaded the font from the dafont.com website:
There were a lot of performance considerations, all in the vacuum.
The issue with this handlers is that you need to curry them in order to incorporate the argument that you can't name in the props.
This means that the component needs a handler for each and every clickable element. Let's agree that for a few buttons this is not an issue, right?
The problem arises when you are handling tabular data with dozens of columns and thousands of rows. There you notice the impact of creating that many handlers.
The fact is, I only need one.
I set the handler at the table level (or UL or OL...), and when the click happens I can tell which was the clicked cell using data available since ever in the event object:
nativeEvent.target.tagName
nativeEvent.target.parentElement.tagName
nativeEvent.target.parentElement.rowIndex
nativeEvent.target.cellIndex
nativeEvent.target.textContent
I use the tagname fields to check that the click happened in a valid element, for example ignore clicks in THs ot footers.
The rowIndex and cellIndex give the exact location of the clicked cell.
Textcontent is the text of the clicked cell.
This way I don't need to pass the cell's data to the handler, it can self-service it.
If I needed more data, data that is not to be displayed, I can use the dataset attribute, or hidden elements.
With some simple DOM navigation it's all at hand.
This has been used in HTML since ever, since PCs were much easier to bog.

Use simply:
ListBox2.Items.Clear()
MSDN: ListBox.ObjectCollection.Clear
Removes all items from the collection.
Note that the problem with your approach is that RemoveAt
changes the index of all remaining items.
When you remove an item from the list, the indexes change for subsequent items in the list. All information about the removed item is deleted. You can use this method to remove a specific item from the list by specifying the index of the item to remove from the list. To specify the item to remove instead of the index to the item, use the Remove method. To remove all items from the list, use the Clear method.
If you want to use RemoveAt
anyway, you can go backwards, for example with:
a for
-loop:
For i As Int32 = ListBox2.Items.Count To 0 Step -1
ListBox2.Items.RemoveAt(i)
Next
or a while
While ListBox2.Items.Count > 0
ListBox2.Items.RemoveAt(ListBox2.Items.Count - 1)
End While
old C# code
for (int i = ListBox2.Items.Count - 1; i >= 0; i--)
ListBox2.Items.RemoveAt(i);
while(ListBox2.Items.Count > 0)
ListBox2.Items.RemoveAt(ListBox2.Items.Count - 1);
The way I got around this was to use some jQuery. The reason I did it this way was because A and B were percent widths.
HTML:
<div class="floatNoWrap">
<div id="A" style="float: left;">
Content A
</div>
<div id="B" style="float: left;">
Content B
</div>
<div style="clear: both;"></div>
</div>
CSS:
.floatNoWrap
{
width: 100%;
height: 100%;
}
jQuery:
$("[class~='floatNoWrap']").each(function () {
$(this).css("width", $(this).outerWidth());
});
Check your git repo before committing
gitrepo/.git/hooks/commit-msg
if this file is not present in that location then you will get this error "missing Change-Id in commit message" .
To solve this just copy paste the commit hook in .git folder.
One other key thing that I found regarding copying rows within a table, is that the worksheet you are working on needs to be activated. If you have a workbook with multiple sheets, you need to save the sheet you called the macro from, and then activate the sheet with the table. Once you are done, you can re-activate the original sheet.
You can use Application.ScreenUpdating = False to make sure the user doesn't see that you are switching worksheets within your macro.
If you don't have the worksheet activated, the copy doesn't seem to work properly, i.e. some stuff seem to work, and other stuff doesn't ??
I wanted the AJAX loaded content removed when the modal closed, so I adjusted the line suggested by others (coffeescript syntax):
$('#my-modal').on 'hidden.bs.modal', (event) ->
$(this).removeData('bs.modal').children().remove()
You can specify it in your IDE. For example, for Eclipse in Run Configurations ? VM arguments. You can enter -Xmx800m -Xms500m
as
I would go with option A:
String.Join(String.Empty, los.ToArray());
My reasoning is because the Join method was written for that purpose. In fact if you look at Reflector, you'll see that unsafe code was used to really optimize it. The other two also WORK, but I think the Join function was written for this purpose, and I would guess, the most efficient. I could be wrong though...
As per @Nuri YILMAZ without .ToArray()
, but this is .NET 4+:
String.Join(String.Empty, los);
Though linkedHashMap doesn't provide any method to get first, last or any specific object.
But its pretty trivial to get :
Map<Integer,String> orderMap = new LinkedHashMap<Integer,String>();
Set<Integer> al = orderMap.keySet();
now using iterator on al
object ; you can get any object.
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;
As others have submitted quadratic worst-case time complexity solution, I'd add a linear one (based on the KMP Algorithm):
bool is_rotation(const string& str1, const string& str2)
{
if(str1.size()!=str2.size())
return false;
vector<size_t> prefixes(str1.size(), 0);
for(size_t i=1, j=0; i<str1.size(); i++) {
while(j>0 && str1[i]!=str1[j])
j=prefixes[j-1];
if(str1[i]==str1[j]) j++;
prefixes[i]=j;
}
size_t i=0, j=0;
for(; i<str2.size(); i++) {
while(j>0 && str2[i]!=str1[j])
j=prefixes[j-1];
if(str2[i]==str1[j]) j++;
}
for(i=0; i<str2.size(); i++) {
if(j>=str1.size()) return true;
while(j>0 && str2[i]!=str1[j])
j=prefixes[j-1];
if(str2[i]==str1[j]) j++;
}
return false;
}
I presume you've got validate_required() function from this page: http://www.w3schools.com/js/js_form_validation.asp?
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}
In this case your last condition will not work as you expect it.
You can replace it with this:
if (password.value != cpassword.value) {
alert("Your password and confirmation password do not match.");
cpassword.focus();
return false;
}
Before actually answering your question:
Parameters in a URL (e.g. key=listOfUsers/user1
) are GET
parameters and you shouldn't be using them for POST
requests. A quick explanation of the difference between GET and POST can be found here.
In your case, to make use of REST principles, you should probably have:
http://ip:5000/users
http://ip:5000/users/<user_id>
Then, on each URL, you can define the behaviour of different HTTP methods (GET
, POST
, PUT
, DELETE
). For example, on /users/<user_id>
, you want the following:
GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id>
So, in your example, you want do a POST
to /users/user_1
with the POST data being "John"
. Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.
Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
if request.method == 'GET':
"""return the information for <user_id>"""
.
.
.
if request.method == 'POST':
"""modify/update the information for <user_id>"""
# you can use <user_id>, which is a str but could
# changed to be int or whatever you want, along
# with your lxml knowledge to make the required
# changes
data = request.form # a multidict containing POST data
.
.
.
if request.method == 'DELETE':
"""delete user with ID <user_id>"""
.
.
.
else:
# POST Error 405 Method Not Allowed
.
.
.
There are a lot of other things to consider like the POST
request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.
Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

I have tested on XP, Vista, Win7 and Win8. All fail when quotes are used.
This line:

The ${

Request.QueryString

example
string http = "http://dave.com/customers.aspx?customername=dave"
string customername = Request.QueryString["customername"].ToString();
so the customername variable should be equal to dave

Open Network panel in Developer Tools by pressing Ctrl+Shift+E or by going Menubar -> Tools -> Web Developer -> Network.

First, you don't need the .class files if they are compiled from your .java classes.
To import your files, you need to create an empty Java project. They you either import them one by one (New -> File -> Advanced -> Link file) or directly copy them into their corresponding folder/package and refresh the project.
GetValue = function(id) {
var tag = this.tagName;
var type = this.attr("type");
if (tag == "input" && (type == "checkbox" || type == "radio"))
return this.is(":checked");
return this.val();
};
Just do:
SET
You can also do SET prefix
to see all variables with names starting with prefix
.
For example, if you want to read only derbydb from the environment variables, do the following:
set derby
...and you will get the following:
DERBY_HOME=c:\Users\amro-a\Desktop\db-derby-10.10.1.1-bin\db-derby-10.10.1.1-bin
I believe you need to do this:
Option 2 Convert to the date format pointed out in Jon Skeet's answer and use that.
You could even do a sub-query. Like this code below:
DELETE FROM users WHERE id IN(
SELECT user_id FROM Employee WHERE Company = '1' AND Date = '2013-05-06'
)
Use a custom Listview.
You can also customize how row looks by having a custom background. activity_main.xml

jQuery is just a library which enhances the capabilities of the DOM within a web browser; the underlying language is JavaScript, which has, as you might hope to expect from a programming language, the ability to perform conditional logic, i.e.
if( condition ) {
// do something
}
Testing two conditions is straightforward, too:
if( A && B ) {
// do something
}
Dear God, I hope this isn't a troll...
If you are looking for the opposite to get a date from a weeknumber i found a solution online and changed it slightly:
Function fnDateFromWeek(iYear As Integer, iWeek As Integer, iWeekDday As Integer)
' get the date from a certain day in a certain week in a certain year
fnDateFromWeek = DateSerial(iYear, 1, (iWeek * 7) _
+ iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
End Function
I took the formular from asap-utilities.com/ and changed
DateSerial(iYear, 1, ((iWeek - 1) * 7)
to
DateSerial(iYear, 1, (iWeek * 7)
It seems that at least for germany the formular works not as expected for the leap year 2016 so i changed it to this
Function fnDateFromWeek(iYear As Integer, iWeek As Integer, iWeekDday As Integer)
' get the date from a certain day in a certain week in a certain year
If isLeapYear(iYear) Then
curDate = DateSerial(iYear, 1, ((iWeek) * 7) _
+ iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
Else
curDate = DateSerial(iYear, 1, ((iWeek - 1) * 7) _
+ iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
End If
fnDateFromWeek = curDate
End Function
Since 2016 hardcoded is not ideal you could check if a year is a leap year with this function
Function isLeapYear(iYear As Integer) As Boolean
If (Month(DateSerial(iYear, 2, 29)) = 2) Then
isLeapYear = True
Else
isLeapYear = False
End If
End Function
For a non-leap-year DateSerial(iYear,2 ,29)
returns 1st of march
This may still be wrong but my limited test gave the expected results:
Sub TestExample()
Debug.Print Format(fnDateFromWeek(2014, 48, 2), "ddd dd mmm yyyy") ' mo 24 Nov 2014
Debug.Print Format(fnDateFromWeek(2015, 11, 6), "ddd dd-mmm-yyyy") ' fr 13 Mar 2015
Debug.Print Format(fnDateFromWeek(2016, 36, 2), "ddd dd-mmm-yyyy") ' Mo 05 Sep 2015
End Sub
use ps aux | grep sshfs

Try using a class method:

return @"Hello World";
}
I use it sometimes.
I got the same error while I forgot to use shell=True
in the subprocess.call
.
subprocess.call('python modify_depth_images.py', shell=True)
To run an external command without interacting with it, such as one would do with
os.system()
, Use thecall()
function.import subprocess Simple command subprocess.call(['ls', '-1'], shell=True)
If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:
curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
"index" : {
"number_of_replicas" : 0
}
}'
Doing this you'll force to use es without replicas
npm install -g npm@version
in which you want to downgrade
npm install -g [email protected]
Use the text-transform CSS for the front-end and then use the toUpper method on your string server-side before you validate.
keep a count of where you are in the primitive array
class recordStuff extends Thread
{
double[] aListOfDoubles;
int i = 0;
void run()
{
double newData;
newData = getNewData(); // gets data from somewhere
aListofDoubles[i] = newData; // adds it to the primitive array of doubles
i++ // increments the counter for the next pass
System.out.println("mode: " + doStuff());
}
void doStuff()
{
// Calculate the mode of the double[] array
for (int i = 0; i < aListOfDoubles.length; i++)
{
int count = 0;
for (int j = 0; j < aListOfDoubles.length; j++)
{
if (a[j] == a[i]) count++;
}
if (count > maxCount)
{
maxCount = count;
maxValue = aListOfDoubles[i];
}
}
return maxValue;
}
}
Confirm in API documentation http://api.jquery.com/jQuery.each/ say:
We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.
and this is my example http://jsfiddle.net/r6jqP/
(function($){
$('#go').on('click',function(){
var i=0,
all=0;
$('li').each(function(){
all++;
if($('#mytext').val()=='continue')return true;
i++;
if($('#mytext').val()==$(this).html()){
return false;
}
});
alert('Iterazione : '+i+' to '+all);
});
}(jQuery));
I assume you're seeing this in a React component's render
method, like this (edit: your edited question does indeed show that):

<div>Children ({this.props.children.length}):</div>_x000D_
{this.props.children}_x000D_
</div>;_x000D_
}_x000D_
}_x000D_
_x000D_
class Widget extends React.Component {_x000D_
render() {_x000D_
return <div>_x000D_
<div>First <code>Example</code>:</div>_x000D_

<div>1</div>_x000D_
<div>2</div>_x000D_

}_x000D_
}_x000D_
_x000D_
ReactDOM.render(_x000D_

children
is a special property of React components which contains any child elements defined within the component, e.g. the divs
inside Example
above. {this.props.children}
includes those children in the rendered result.
...what are the situations to use the same
You'd do it when you want to include the child elements in the rendered output directly, unchanged; and not if you didn't.
This feature shud have come built in Ios, however we need to do externally.
Insert the below code
* To move view when textField is under keyboard,
* Not to move view when textField is above keyboard
* To move View based on the height of the keyboard when needed.

An Object becomes eligible for Garbage collection or GC if its not reachable from any live threads or any static refrences in other words you can say that an object becomes eligible for garbage collection if its all references are null. Cyclic dependencies are not counted as reference so if Object A has reference of object B and object B has reference of Object A and they don't have any other live reference then both Objects A and B will be eligible for Garbage collection. Generally an object becomes eligible for garbage collection in Java on following cases:
I found no answer to be what I needed and that is as easy as:
git add -A
git reset HEAD fileThatYouWantToStash
git commit -m "committing all but one file"
git stash
This stashes exactly one file.
I've been down this road and eventually opted for a hardware data scope that does non-instrusive in-line monitoring. The software solutions that I tried didn't work for me. If you had a spare PC you could probably build one, albeit rather bulky. This software data scope may work, as might this, but I haven't tried either.
The accepted answer has some holes in it. The beauty of the SparseArray is that it allows gaps in the indeces. So, we could have two maps like so, in a SparseArray...
(0,true)
(250,true)
Notice the size here would be 2. If we iterate over size, we will only get values for the values mapped to index 0 and index 1. So the mapping with a key of 250 is not accessed.
for(int i = 0; i < sparseArray.size(); i++) {
int key = sparseArray.keyAt(i);
// get the object by the key.
Object obj = sparseArray.get(key);
}
The best way to do this is to iterate over the size of your data set, then check those indeces with a get() on the array. Here is an example with an adapter where I am allowing batch delete of items.
for (int index = 0; index < mAdapter.getItemCount(); index++) {
if (toDelete.get(index) == true) {
long idOfItemToDelete = (allItems.get(index).getId());
mDbManager.markItemForDeletion(idOfItemToDelete);
}
}
I think ideally the SparseArray family would have a getKeys() method, but alas it does not.
According to MSDN maxAllowedContentLength
has type uint
, its maximum value is 4,294,967,295 bytes = 3,99 gb
So it should work fine.

Your Javascript should be

autoplayTimeout: 5000,
autoplayHoverPause: true
)}

Create a button with an id share and add the following code snippet.
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "Your body here";
String shareSub = "Your subject here";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, shareSub);
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share using"));
}
});
The above code snippet will open the share chooser on share button click action. However, note...The share code snippet might not output very good results using emulator. For actual results, run the code snippet on android device to get the real results.
Can I try? ;)
