There are no performance implications since the compiler will translate your lambda expression into an equivalent delegate. Lambda expressions are nothing more than a language feature that the compiler translates into the exact same code that you are used to working with.
The compiler will convert the code you have to something like this:
public partial class MyPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//snip
MyButton.Click += new EventHandler(delegate (Object o, EventArgs a)
{
//snip
});
}
}
try this

For the EditText if we specify,
android:inputType="number"
only numbers can be got. But if you use,
android:inputType="phone"
along with the numbers it can accept special characters like ;,/". etc.
As already mentioned, awk is the right tool for this. If you don't want to use awk, instead of parsing output of "ls -l" line by line, you could iterate over all files and do an "ls -l" for each individual file like this:
for x in * ; do echo `ls -ld $x` ; done
You typically restore purchases with this code:
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
It will reinvoke -paymentQueue:updatedTransactions
on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.
Not all types of In-App purchases can be restored.

Set Cookie?
res.cookie('cookieName', 'cookieValue')
Read Cookie?
req.cookies
Demo
const express('express')
, cookieParser = require('cookie-parser'); // in order to read cookie sent from client
app.get('/', (req,res)=>{
// read cookies
console.log(req.cookies)
let options = {
maxAge: 1000 * 60 * 15, // would expire after 15 minutes
httpOnly: true, // The cookie only accessible by the web server
signed: true // Indicates if the cookie should be signed
}
// Set cookie
res.cookie('cookieName', 'cookieValue', options) // options is optional
res.send('')
})
You can use this as well:
values = np.array([[1,2,3],[4,5,6]])
values[...,0] # first column
#[1,4]
Note: This is not working for built-in array and not aligned (e.g. np.array([[1,2,3],[4,5,6,7]]) )
I have found this on MS connect:
Yes, you need to install Visual Studio 2010 on your build machine to build database projects. Doing so does not require an additional license of Visual Studio.
So, this is the only option that I have for now.
Import into the database:
mysql -u username -p database_name < /file path/file_name.sql
Export from the database:
mysqldump -u username -p database_name > /file path/file_name.sql
After these commands, a prompt will ask for your MySQL password.
Use IsNumeric Function :
IsNumeric(number)
If you want to validate a phone number you should use a regular expression, for example:
^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{3})$
Yes, easy. Just run a data-definition query to update the tables, adding an AUTO_INCREMENT column.
If you have an existing database, be careful to preserve any foreign-key relationships that might already be there on the "artificially created" primary keys.
You should call this function from the controller.
angular.module('App', [])
.controller('CinemaCtrl', ['$scope', function($scope) {
myFunction();
}]);
Even with normal javascript/html your function won't run on page load as all your are doing is defining the function, you never call it. This is really nothing to do with angular, but since you're using angular the above would be the "angular way" to invoke the function.
Obviously better still declare the function in the controller too.
Edit: Actually I see your "onload" - that won't get called as angular injects the HTML into the DOM. The html is never "loaded" (or the page is only loaded once).
I change the views folder name to views_render and also facing the same issue as above, so restart server.js and it works for me.
In jquery, u can delcare variable two styles.
One is,
$.name = 'anirudha';
alert($.name);
Second is,
var hText = $("#head1").text();
Second is used when you read data from textbox
, label
, etc.
I myself landed on these answers last day, trying to find a way to deep copy complex structures, which may include recursive links. As I wasn't satisfied with anything being suggested before, I implemented this wheel myself. And it works quite well. Hope it helps someone.
Example usage:
OriginalStruct.deep_copy = deep_copy; // attach the function as a method
TheClone = OriginalStruct.deep_copy();
Please look at https://github.com/latitov/JS_DeepCopy for live examples how to use it, and also deep_print() is there.
If you need it quick, right here's the source of deep_copy() function:
function deep_copy() {
'use strict'; // required for undef test of 'this' below
// Copyright (c) 2019, Leonid Titov, Mentions Highly Appreciated.
var id_cnt = 1;
var all_old_objects = {};
var all_new_objects = {};
var root_obj = this;
if (root_obj === undefined) {
console.log(`deep_copy() error: wrong call context`);
return;
}
var new_obj = copy_obj(root_obj);
for (var id in all_old_objects) {
delete all_old_objects[id].__temp_id;
}
return new_obj;
//
function copy_obj(o) {
var new_obj = {};
if (o.__temp_id === undefined) {
o.__temp_id = id_cnt;
all_old_objects[id_cnt] = o;
all_new_objects[id_cnt] = new_obj;
id_cnt ++;
for (var prop in o) {
if (o[prop] instanceof Array) {
new_obj[prop] = copy_array(o[prop]);
}
else if (o[prop] instanceof Object) {
new_obj[prop] = copy_obj(o[prop]);
}
else if (prop === '__temp_id') {
continue;
}
else {
new_obj[prop] = o[prop];
}
}
}
else {
new_obj = all_new_objects[o.__temp_id];
}
return new_obj;
}
function copy_array(a) {
var new_array = [];
if (a.__temp_id === undefined) {
a.__temp_id = id_cnt;
all_old_objects[id_cnt] = a;
all_new_objects[id_cnt] = new_array;
id_cnt ++;
a.forEach((v,i) => {
if (v instanceof Array) {
new_array[i] = copy_array(v);
}
else if (v instanceof Object) {
new_array[i] = copy_object(v);
}
else {
new_array[i] = v;
}
});
}
else {
new_array = all_new_objects[a.__temp_id];
}
return new_array;
}
}

I encountered the same need and make a universal solution (node+browser) that works with the Next.js framework, for instance.
It even works with circular dependencies (thanks to json-stringify-safe
).
Although, I also built a serializer on top of it to remove unnecessary data (because it's not recommended to use a url longer than 2k chars, see What is the maximum length of a URL in different browsers?)
import StringifySafe from 'json-stringify-safe';
export const encodeQueryParameter = (data: object): string => {
return encodeURIComponent(StringifySafe(data)); // Use StringifySafe to avoid crash on circular dependencies
};
export const decodeQueryParameter = (query: string): object => {
return JSON.parse(decodeURIComponent(query));
};
And the unit tests (jest):
import { decodeQueryParameter, encodeQueryParameter } from './url';
export const data = {
'organisation': {
'logo': {
'id': 'ck2xjm2oj9lr60b32c6l465vx',
'linkUrl': null,
'linkTarget': '_blank',
'classes': null,

},
};
export const encodedData = '%7B%22organisation%22%3A%7B%22logo%22%3A%7B%22id%22%3A%22ck2xjm2oj9lr60b32c6l465vx%22%2C%22linkUrl%22%3Anull%2C%22linkTarget%22%3A%22_blank%22%2C%22classes%22%3Anull%2C%22style%22%3Anull%2C%22defaultTransformations%22%3A%7B%22width%22%3A200%2C%22height%22%3A200%2C%22__typename%22%3A%22AssetTransformations%22%7D%2C%22mimeType%22%3A%22image%2Fpng%22%2C%22__typename%22%3A%22Asset%22%7D%2C%22theme%22%3A%7B%22primaryColor%22%3A%22%231134e6%22%2C%22primaryAltColor%22%3A%22%23203a51%22%2C%22secondaryColor%22%3A%22white%22%2C%22font%22%3A%22neuzeit-grotesk%22%2C%22__typename%22%3A%22Theme%22%2C%22primaryColorG1%22%3A%22%23ffffff%22%7D%7D%7D';

I had the same problem and tried most of the solutions suggested above, but none worked for me. Eventually, I rebuild my entire com.springframework (maven) repository (by simply deleting .m2/org/springworkframework directory).
It worked for me.
You need to move the unique_ptr
:
vec.push_back(std::move(ptr2x));
unique_ptr
guarantees that a single unique_ptr
container has ownership of the held pointer. This means that you can't make copies of a unique_ptr
(because then two unique_ptr
s would have ownership), so you can only move it.
Note, however, that your current use of unique_ptr
is incorrect. You cannot use it to manage a pointer to a local variable. The lifetime of a local variable is managed automatically: local variables are destroyed when the block ends (e.g., when the function returns, in this case). You need to dynamically allocate the object:
std::unique_ptr<int> ptr(new int(1));
In C++14 we have an even better way to do so:
make_unique<int>(5);
You can make use of df.as_matrix() function and create Numpy-array and pass it.
Y = df.pop()
X = df.as_matrix()
x_train, x_test, y_train, y_test = train_test_split(X, Y, test_size = 0.2)
model.fit(x_train, y_train)
model.test(x_test)
Use str.join
:
In [27]: mylist = ['10', '12', '14']
In [28]: print '\n'.join(mylist)
10
12
14
The shorthand for $(document).ready(handler)
is $(handler)
(where handler
is a function). See here.
The code in your question has nothing to do with .ready()
. Rather, it is an immediately-invoked function expression (IIFE) with the jQuery object as its argument. Its purpose is to restrict the scope of at least the $
variable to its own block so it doesn't cause conflicts. You typically see the pattern used by jQuery plugins to ensure that $ == jQuery
.
For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:
describe('SignInUser', () => {
var history = {
push: function(str) {
expect(str).toEqual('/feed');
}
}
it('Dispatches authorization', () => {
let mock = new MockAdapter(axios);
mock.onPost(`${ROOT_URL}/auth/signin`, {
email: '[email protected]',
password: 'test'
}).reply(200, {token: 'testToken' });
const expectedActions = [ { type: types.AUTH_USER } ];
const store = mockStore({ auth: [] });
return store.dispatch(actions.signInUser({
email: '[email protected]',
password: 'test',
}, history)).then(() => {
expect(store.getActions()).toEqual(expectedActions);
});
});
In order to test a successful case for signInUser
in file actions/index.js:
export const signInUser = ({ email, password }, history) => async dispatch => {
const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
.catch(({ response: { data } }) => {
...
});
if (res) {
dispatch({ type: AUTH_USER }); // Test verified this
localStorage.setItem('token', res.data.token); // Test mocked this
history.push('/feed'); // Test mocked this
}
}
Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:
const localStorageMock = {
removeItem: jest.fn(),
getItem: jest.fn(),
setItem: jest.fn(),
clear: jest.fn()
};
global.localStorage = localStorageMock;
Please check if you have already close the database connection or not. In my case i was getting the error because the connection was close in upper line.
Just use the . at the end of the git clone
command (being in that directory), like this:
cd your_dir_to_clone_in/
git clone [email protected]/somerepo/ .
I'm going to approach this as if you have a Users model:
Users.cs
public class Users
{
[Key]
public int UserId { get; set; }
[Required]
public string UserName { get; set; }
public int RoleId { get; set; }
[ForeignKey("RoleId")]
public virtual DbUserRoles DbUserRoles { get; set; }
}
and a DbUserRoles model that represented a table by that name in the database:
DbUserRoles.cs
public partial class DbUserRoles
{
[Key]
public int UserRoleId { get; set; }
[Required]
[StringLength(30)]
public string UserRole { get; set; }
}
Once you had that cleaned up, you should just be able to create and fill a collection of UserRoles, like this, in your Controller:
var userRoleList = GetUserRolesList();
ViewData["userRoles"] = userRolesList;
and have these supporting functions:
private static SelectListItem[] _UserRolesList;
/// <summary>
/// Returns a static category list that is cached
/// </summary>
/// <returns></returns>
public SelectListItem[] GetUserRolesList()
{
if (_UserRolesList == null)
{
var userRoles = repository.GetAllUserRoles().Select(a => new SelectListItem()
{
Text = a.UserRole,
Value = a.UserRoleId.ToString()
}).ToList();
userRoles.Insert(0, new SelectListItem() { Value = "0", Text = "-- Please select your user role --" });
_UserRolesList = userRoles.ToArray();
}
// Have to create new instances via projection
// to avoid ModelBinding updates to affect this
// globally
return _UserRolesList
.Select(d => new SelectListItem()
{
Value = d.Value,
Text = d.Text
})
.ToArray();
}
Repository.cs
My Repository function GetAllUserRoles()
for the function, above:
public class Repository
{
Model1 db = new Model1(); // Entity Framework context
// User Roles
public IList<DbUserRoles> GetAllUserRoles()
{
return db.DbUserRoles.OrderBy(e => e.UserRoleId).ToList();
}
}
AddNewUser.cshtml
Then do this in your View:
<table>
<tr>
<td>
@Html.EditorFor(model => model.UserName,
htmlAttributes: new { @class = "form-control" }
)
</td>
<td>
@Html.DropDownListFor(model => model.RoleId,
new SelectList( (IEnumerable<SelectListItem>)ViewData["userRoles"], "Value", "Text", model.RoleId),
htmlAttributes: new { @class = "form-control" }
)
</td>
</tr>
</table>
With React-Native 0.56, the above method of changing Text.prototype.render
does not work anymore, so you have to use your own component, which can be done in one line!
MyText.js
export default props => <Text {...props} style={[{fontFamily: 'Helvetica'}, props.style]}>{props.children}</Text>
AnotherComponent.js
import Text from './MyText';
...
<Text>This will show in default font.</Text>
...
Maybe you can use the onResourceRequested
and onResourceReceived
callbacks to detect asynchronous loading. Here's an example of using those callbacks from their documentation:
var page = require('webpage').create();
page.onResourceRequested = function (request) {
console.log('Request ' + JSON.stringify(request, undefined, 4));
};
page.onResourceReceived = function (response) {
console.log('Receive ' + JSON.stringify(response, undefined, 4));
};
page.open(url);
Also, you can look at examples/netsniff.js
for a working example.
here is how to validate the input to only accept numbers this will accept numbers like 123123123.41212313
<input type="text"
onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;"
/>
and this will not accept entering the dot (.), so it will only accept integers
<input type="text"
onkeypress="if ( isNaN( String.fromCharCode(event.keyCode) )) return false;"
/>
this way you will not permit the user to input anything but numbers
The closest you say... Let me think... This must be fork() I guess :)
For details see Does Interix implement fork()?
I searched lots of methods and i did it my own way. You have to open a connection between two machine via command prompt NET USE command and after finishing your work clear the connection with command prompt NET USE "myconnection" /delete.
You must use Command Prompt process from code behind like this:
var savePath = @"\\servername\foldername\myfilename.jpg";
var filePath = @"C:\\temp\myfileTosave.jpg";
Usage is simple:
SaveACopyfileToServer(filePath, savePath);
Here is functions:
using System.IO
using System.Diagnostics;
public static void SaveACopyfileToServer(string filePath, string savePath)
{
var directory = Path.GetDirectoryName(savePath).Trim();
var username = "loginusername";
var password = "loginpassword";
var filenameToSave = Path.GetFileName(savePath);
if (!directory.EndsWith("\\"))
filenameToSave = "\\" + filenameToSave;
var command = "NET USE " + directory + " /delete";
ExecuteCommand(command, 5000);
command = "NET USE " + directory + " /user:" + username + " " + password;
ExecuteCommand(command, 5000);
command = " copy \"" + filePath + "\" \"" + directory + filenameToSave + "\"";
ExecuteCommand(command, 5000);
command = "NET USE " + directory + " /delete";
ExecuteCommand(command, 5000);
}
And also ExecuteCommand function is:
public static int ExecuteCommand(string command, int timeout)
{
var processInfo = new ProcessStartInfo("cmd.exe", "/C " + command)
{
CreateNoWindow = true,
UseShellExecute = false,
WorkingDirectory = "C:\\",
};
var process = Process.Start(processInfo);
process.WaitForExit(timeout);
var exitCode = process.ExitCode;
process.Close();
return exitCode;
}
This functions worked very fast and stable for me.
Having been bitten by this, I have a habit of including locally defined variables in the innermost scope which I use to transfer to any closure. In your example:
foreach (var s in strings)
query = query.Where(i => i.Prop == s); // access to modified closure
I do:
foreach (var s in strings)
{
string search = s;
query = query.Where(i => i.Prop == search); // New definition ensures unique per iteration.
}
Once you have that habit, you can avoid it in the very rare case you actually intended to bind to the outer scopes. To be honest, I don't think I have ever done so.
TimezoneDb provides a free API: http://timezonedb.com/api
GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.
You can use Greenwich, UK if you'd like GMT.
To enhance furthermore the useful .toDOM() snippet that we can find in different places, we can now safely use backticks (template literals).
So we can have single and double quotes in the foo html declaration.
This behave like heredocs for those familiar with the term.
This can be enhanced furthermore with variables, to make complex templating:
Template literals are enclosed by the back-tick (
) (grave accent) character instead of double or single quotes. Template literals can contain placeholders. These are indicated by the dollar sign and curly braces (${expression}). The expressions in the placeholders and the text between them get passed to a function. The default function just concatenates the parts into a single string. If there is an expression preceding the template literal (tag here), this is called a "tagged template". In that case, the tag expression (usually a function) gets called with the processed template literal, which you can then manipulate before outputting. To escape a back-tick in a template literal, put a backslash \ before the back-tick.

So, why not use directly .innerHTML +=
?
By doing so, the whole DOM is being recalculated by the browser, it's much slower.
I have <M-DOWN>
(alt down arrow) mapped to <DOWN>.
so that I can repeat the last command on a series of lines very quickly. with this mapping I can:
A,<ESC>
And then hold alt while pressing down repeatedly to append the comma to the end of each line.
This works well for me because it allows very good control over what lines do and do not get the change.
(I also have the other arrows mapped similarly to allow for easy repeating of .
)
Here's the mapping line to paste into your vimrc:
map <M-DOWN> <DOWN>.
Why not use document.documentMode
only available under IE:
var doc = $window.document;
if (!!doc.documentMode)
{
if (doc.documentMode === 10)
{
doc.documentElement.className += ' isIE isIE10';
}
else if (doc.documentMode === 11)
{
doc.documentElement.className += ' isIE isIE11';
}
// etc.

To show the backdrop, you'll need something like this CSS:
.modal {
background: rgba(0,0,0,0.6);
}
The example now allows for multiple modals at the same time. (see the onContainerClicked()
method).
For Bootstrap 4 css users, you need to make 1 minor change (because a css class name was updated from Bootstrap 3). This line:
[ngClass]="{'in': visibleAnimate}"
should be changed to:
[ngClass]="{'show': visibleAnimate}"

If you use a virtual environment and Windows 10 (maybe it's the same for other systems), you just need to put geckodriver.exe into the following folder in your virtual environment directory:
...\my_virtual_env_directory\Scripts\geckodriver.exe
If you want to give your user all read permissions, you could use:
EXEC sp_addrolemember N'db_datareader', N'your-user-name'
That adds the default db_datareader
role (read permission on all tables) to that user.
There's also a db_datawriter
role - which gives your user all WRITE permissions (INSERT, UPDATE, DELETE) on all tables:
EXEC sp_addrolemember N'db_datawriter', N'your-user-name'
If you need to be more granular, you can use the GRANT
command:
GRANT SELECT, INSERT, UPDATE ON dbo.YourTable TO YourUserName
GRANT SELECT, INSERT ON dbo.YourTable2 TO YourUserName
GRANT SELECT, DELETE ON dbo.YourTable3 TO YourUserName
and so forth - you can granularly give SELECT, INSERT, UPDATE, DELETE permission on specific tables.
This is all very well documented in the MSDN Books Online for SQL Server.
And yes, you can also do it graphically - in SSMS, go to your database, then Security > Users
, right-click on that user you want to give permissions to, then Properties
adn at the bottom you see "Database role memberships" where you can add the user to db roles.
You can do the following:
Python 2.x
import hashlib
print hashlib.md5("whatever your string is").hexdigest()
Python 3.x
import hashlib
print(hashlib.md5("whatever your string is".encode('utf-8')).hexdigest())
However in this case you're probably better off using this helpful Python module for interacting with the Flickr API:
... which will deal with the authentication for you.

The Authenticity Token is a countermeasure to Cross-Site Request Forgery (CSRF). What is CSRF, you ask?
It's a way that an attacker can potentially hijack sessions without even knowing session tokens.
Scenario:
CSRF solution:
I dug myself into a slight variant on this problem by mistakenly running the setfacl
command. I ran:
sudo setfacl -m user:nginx:r /home/foo/bar
I abandoned this route in favor of adding nginx
to the foo
group, but that custom ACL was foiling nginx's attempts to access the file. I cleared it by running:
sudo setfacl -b /home/foo/bar
And then nginx was able to access the files.
Very generic "All-In-One" Function (not recommended though):
function is_empty(x)
{
return ( //don't put newline after return
(typeof x == 'undefined')
||
(x == null)
||
(x == false) //same as: !x
||
(x.length == 0)
||
(x == 0) // note this line, you might not need this.
||
(x == "")
||
(x.replace(/\s/g,"") == "")
||
(!/[^\s]/.test(x))
||
(/^\s*$/.test(x))
);
}
However, I don't recommend to use that, because your target variable should be of specific type (i.e. string, or numeric, or object?), so apply the checks that are relative to that variable.
Your pkl
file is, in fact, a serialized pickle
file, which means it has been dumped using Python's pickle
module.
To un-pickle the data you can:
import pickle
with open('serialized.pkl', 'rb') as f:
data = pickle.load(f)
Note gzip
is only needed if the file is compressed:
import gzip
import pickle
with gzip.open('mnist.pkl.gz', 'rb') as f:
train_set, valid_set, test_set = pickle.load(f)
Where each set can be further divided (i.e. for the training set):
train_x, train_y = train_set
Those would be the inputs (digits) and outputs (labels) of your sets.
If you want to display the digits:
import matplotlib.cm as cm
import matplotlib.pyplot as plt
plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()
The other alternative would be to look at the original data:
http://yann.lecun.com/exdb/mnist/
But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle
. As you've seen, it's very easy. ;-)
Try going with Switch case or ternary operator
render(){
return (
<div>
<Element1/>
<Element2/>
// updated code works here
{(() => {
switch (this.props.hasImage) {
case (this.props.hasImage):
return <MyImage />;
default:
return (
<OtherElement/>;
);
}
})()}
</div>
)
}
This worked for me and should work for you else. Try Ternary Operator
Here is a method to merge a dictionary of data frames while keeping the column names in sync with the dictionary. Also it fills in missing values if needed:
def MergeDfDict(dfDict, onCols, how='outer', naFill=None):
keys = dfDict.keys()
for i in range(len(keys)):
key = keys[i]
df0 = dfDict[key]
cols = list(df0.columns)
valueCols = list(filter(lambda x: x not in (onCols), cols))
df0 = df0[onCols + valueCols]
df0.columns = onCols + [(s + '_' + key) for s in valueCols]
if (i == 0):
outDf = df0
else:
outDf = pd.merge(outDf, df0, how=how, on=onCols)
if (naFill != None):
outDf = outDf.fillna(naFill)
return(outDf)
def GenDf(size):
df = pd.DataFrame({'categ1':np.random.choice(a=['a', 'b', 'c', 'd', 'e'], size=size, replace=True),
'categ2':np.random.choice(a=['A', 'B'], size=size, replace=True),
'col1':np.random.uniform(low=0.0, high=100.0, size=size),
'col2':np.random.uniform(low=0.0, high=100.0, size=size)
})
df = df.sort_values(['categ2', 'categ1', 'col1', 'col2'])
return(df)
size = 5
dfDict = {'US':GenDf(size), 'IN':GenDf(size), 'GER':GenDf(size)}
MergeDfDict(dfDict=dfDict, onCols=['categ1', 'categ2'], how='outer', naFill=0)
AFAIK, unit testing is NOT functional testing. Let me explain with a small example. You want to test if the login functionality of an email web app is working or not, just as a user would. For that, your functional tests should be like this.
1- existing email, wrong password -> login page should show error "wrong password"!
2- non-existing email, any password -> login page should show error "no such email".
3- existing email, right password -> user should be taken to his inbox page.
4- no @symbol in email, right password -> login page should say "errors in form, please fix them!"
Should our functional tests check if we can login with invalid inputs ? Eg. Email has no @ symbol, username has more than one dot (only one dot is permitted), .com appears before @ etc. ? Generally, no ! That kind of testing goes into your unit tests.
You can check if invalid inputs are rejected inside unit tests as shown in the tests below.
class LoginInputsValidator
method validate_inputs_values(email, password)
1-If email is not like [email protected], then throw error.
2-If email contains abusive words, then throw error.
3-If password is less than 10 chars, throw error.
Notice that the functional test 4 is actually doing what unit test 1 is doing. Sometimes, functional tests can repeat some (not all) of the testing done by unit tests, for different reasons. In our example, we use functional test 4 to check if a particular error message appears on entering invalid input. We don't want to test if all bad inputs are rejected or not. That is the job of unit tests.
I managed to fix this by changing settings for new projects:
File -> New Projects Settings -> Settings for New Projects -> Java Compiler -> Set the version
File -> New Projects Settings -> Structure for New Projects -> Project -> Set Project SDK + set language level
Remove the projects
Import the projects
Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").
When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.
The Collections.sort is a good sort implementation. If you don't have The comparable implemented for Contact, you will need to pass in a Comparator implementation
Of note:
The sorting algorithm is a modified mergesort (in which the merge is omitted if the highest element in the low sublist is less than the lowest element in the high sublist). This algorithm offers guaranteed n log(n) performance. The specified list must be modifiable, but need not be resizable. This implementation dumps the specified list into an array, sorts the array, and iterates over the list resetting each element from the corresponding position in the array. This avoids the n2 log(n) performance that would result from attempting to sort a linked list in place.
The merge sort is probably better than most search algorithm you can do.
If you want a quick and easy solution (and you have gulp installed).
In my gulpfile.js
I run a simple copy paste task that puts any files I might need into ./public/modules/
directory.
gulp.task('modules', function() {
sources = [
'./node_modules/prismjs/prism.js',
'./node_modules/prismjs/themes/prism-dark.css',
]
gulp.src( sources ).pipe(gulp.dest('./public/modules/'));
});
gulp.task('copy-modules', ['modules']);
The downside to this is that it isn't automated. However, if all you need is a few scripts and styles copied over (and kept in a list), this should do the job.
If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn't work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors:
public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_BLACK = "\u001B[30m";
public static final String ANSI_RED = "\u001B[31m";
public static final String ANSI_GREEN = "\u001B[32m";
public static final String ANSI_YELLOW = "\u001B[33m";
public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";
Then, you could reference those as necessary.
For example, using the above constants, you could make the following red text output on supported terminals:
System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);
Update: You might want to check out the Jansi library. It provides an API and has support for Windows using JNI. I haven't tried it yet; however, it looks promising.
Update 2: Also, if you wish to change the background color of the text to a different color, you could try the following as well:
public static final String ANSI_BLACK_BACKGROUND = "\u001B[40m";
public static final String ANSI_RED_BACKGROUND = "\u001B[41m";
public static final String ANSI_GREEN_BACKGROUND = "\u001B[42m";
public static final String ANSI_YELLOW_BACKGROUND = "\u001B[43m";
public static final String ANSI_BLUE_BACKGROUND = "\u001B[44m";
public static final String ANSI_PURPLE_BACKGROUND = "\u001B[45m";
public static final String ANSI_CYAN_BACKGROUND = "\u001B[46m";
public static final String ANSI_WHITE_BACKGROUND = "\u001B[47m";
For instance:
System.out.println(ANSI_GREEN_BACKGROUND + "This text has a green background but default text!" + ANSI_RESET);
System.out.println(ANSI_RED + "This text has red text but a default background!" + ANSI_RESET);
System.out.println(ANSI_GREEN_BACKGROUND + ANSI_RED + "This text has a green background and red text!" + ANSI_RESET);
Now you don't need to add the public
to the methods to test then.
On newer versions of Swift it's only necessary to add the @testable
keyword.
PrimeNumberModelTests.swift
import XCTest
@testable import MyProject
class PrimeNumberModelTests: XCTestCase {
let testObject = PrimeNumberModel()
}
And your internal methods can keep Internal
PrimeNumberModel.swift
import Foundation
class PrimeNumberModel {
init() {
}
}
Note that private
(and fileprivate
) symbols are not available even with using @testable
.
There are two relevant concepts from Swift here (As Xcode 6 beta 6).
Internal access
Considering that tests are on another target on PrimeNumberModelTests.swift
you need to import
the target that contains the class that you want to test, if your target is called MyProject
will need to add import MyProject
to the PrimeNumberModelTests
:
PrimeNumberModelTests.swift
import XCTest
import MyProject
class PrimeNumberModelTests: XCTestCase {
let testObject = PrimeNumberModel()
}
But this is not enough to test your class PrimeNumberModel
, since the default Access Control level is Internal Access
, your class won't be visible to the test bundle, so you need to make it Public Access
and all the methods that you want to test:
PrimeNumberModel.swift
import Foundation
public class PrimeNumberModel {
public init() {
}
}
as @DLeh says Use rather
var controller = DependencyResolver.Current.GetService<ControllerB>();
But, giving the controller, a controlller context is important especially when you need to access the User
object, Server
object, or the HttpContext
inside the 'child' controller.
I have added a line of code:
controller.ControllerContext = new ControllerContext(Request.RequestContext, controller);
or else you could have used System.Web to acces the current context too, to access Server
or the early metioned objects
NB: i am targetting the framework version 4.6 (Mvc5)
To find the sessions, as a DBA use
select sid,serial# from v$session where username = '<your_schema>'
If you want to be sure only to get the sessions that use SQL Developer, you can add and program = 'SQL Developer'
. If you only want to kill sessions belonging to a specific developer, you can add a restriction on os_user
Then kill them with
alter system kill session '<sid>,<serial#>'
(e.g.
alter system kill session '39,1232'
)
A query that produces ready-built kill-statements could be
select 'alter system kill session ''' || sid || ',' || serial# || ''';' from v$session where username = '<your_schema>'
This will return one kill statement per session for that user - something like:
alter system kill session '375,64855';
alter system kill session '346,53146';
A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.
Update 27 Feb 2015: My original answer keeps getting voted up, but now I normally use @bobince's approach instead.
.child { /* This is the item to center... */
display: inline-block;
}
.parent { /* ...and this is its parent container. */
text-align: center;
}
My original post for historical purposes:
You might want to try this approach.
<div class="product_container">
<div class="outer-center">
<div class="product inner-center">
</div>
</div>
<div class="clear"/>
</div>
Here's the matching style:
.outer-center {
float: right;
right: 50%;
position: relative;
}
.inner-center {
float: right;
right: -50%;
position: relative;
}
.clear {
clear: both;
}
The idea here is that you contain the content you want to center in two divs, an outer one and an inner one. You float both divs so that their widths automatically shrink to fit your content. Next, you relatively position the outer div with it's right edge in the center of the container. Lastly, you relatively position the inner div the opposite direction by half of its own width (actually the outer div's width, but they are the same). Ultimately that centers the content in whatever container it's in.
You may need that empty div at the end if you depend on your "product" content to size the height for the "product_container".
if you want to do screen capture from Java code in Android app AFAIK you must have Root provileges.
If you're looking for a method that's easy, then you might want to try this.
I for myself can hardly remember commandlines for all of my tools, so I tend to do it using the UI:
1. First, select "commit"
2. Then, display ignored files. If you have uncommitted changes, hide them.
3. Now, select all of them and click "Delete Unversioned".
Done. It's a procedure that is far easier to remember than commandline stuff.
For me, the only thing which worked is
git diff HEAD
including the staged files, git diff --cached
only shows staged files.
In response to your first question: Yes, you have to run a server app to send the messages, as well as a client app to receive them.
In response to your second question: Yes, every application needs its own API key. This key is for your server app, not the client.
Try like this:
select field1, array_to_string(array_agg(field2), ',')
from table1
group by field1;
In my case, I see the window, but no messages in it. Only restart (studio version 1.5.1) brought the messages back.
I know it not right way. It is not break the loop. It is a Jugad
let result = true;_x000D_
[1, 2, 3].forEach(function(el) {_x000D_
if(result){_x000D_
console.log(el);_x000D_
if (el === 2){_x000D_
result = false;_x000D_
}_x000D_
}_x000D_
});
_x000D_
This worked for me:
def smallest_missing_positive_integer(A):
A.sort()
N = len(A)
now = A[0]
for i in range(1, N, 1):
next = A[i]
#check if there is no gap between 2 numbers and if positive
# "now + 1" is the "gap"
if (next > now + 1):
if now + 1 > 0:
return now + 1 #return the gap
now = next
return max(1, A[N-1] + 1) #if there is no positive number returns 1, otherwise the end of A+1
As the answers above point out, there are a number of ways to determine the most significant bit. However, as was also pointed out, the methods are likely to be unique to either 32bit or 64bit registers. The stanford.edu bithacks page provides solutions that work for both 32bit and 64bit computing. With a little work, they can be combined to provide a solid cross-architecture approach to obtaining the MSB. The solution I arrived at that compiled/worked across 64 & 32 bit computers was:
#if defined(__LP64__) || defined(_LP64)
# define BUILD_64 1
#endif
#include <stdio.h>
#include <stdint.h> /* for uint32_t */
/* CHAR_BIT (or include limits.h) */
#ifndef CHAR_BIT
#define CHAR_BIT 8
#endif /* CHAR_BIT */
/*
* Find the log base 2 of an integer with the MSB N set in O(N)
* operations. (on 64bit & 32bit architectures)
*/
int
getmsb (uint32_t word)
{
int r = 0;
if (word < 1)
return 0;
#ifdef BUILD_64
union { uint32_t u[2]; double d; } t; // temp
t.u[__FLOAT_WORD_ORDER==LITTLE_ENDIAN] = 0x43300000;
t.u[__FLOAT_WORD_ORDER!=LITTLE_ENDIAN] = word;
t.d -= 4503599627370496.0;
r = (t.u[__FLOAT_WORD_ORDER==LITTLE_ENDIAN] >> 20) - 0x3FF;
#else
while (word >>= 1)
{
r++;
}
#endif /* BUILD_64 */
return r;
}
What about this small piece of code:
function splitME(str, size) {
let subStr = new RegExp('.{1,' + size + '}', 'g');
return str.match(subStr);
};
Using jQuery:
var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');
jsonObj
is your JSON object.
Use Thread.sleep(100);
.
The unit of time is milliseconds
For example:
public class SleepMessages {
public static void main(String args[])
throws InterruptedException {
String importantInfo[] = {
"Mares eat oats",
"Does eat oats",
"Little lambs eat ivy",
"A kid will eat ivy too"
};
for (int i = 0;
i < importantInfo.length;
i++) {
//Pause for 4 seconds
Thread.sleep(4000);
//Print a message
System.out.println(importantInfo[i]);
}
}
}
Another alternative is numpy.broadcast_to(val,n)
which returns in constant time regardless of the size and is also the most memory efficient (it returns a view of the repeated element). The caveat is that the returned value is read-only.
Below is a comparison of the performances of all the other methods that have been proposed using the same benchmark as in Nico Schlömer's answer.
document.referrer is not working always.
You can use:
window.location.origin
I'm a bit late to the game, but I noticed some key points that were left out, particularly regarding Java 8 and the efficiency of Arrays.asList
.
As Ciro Santilli ???? ??? ??? pointed out, there's a handy utility for examining bytecode that ships with the JDK: javap
. Using that, we can determine that the following two code snippets produce identical bytecode as of Java 8u74:
int[] arr = {1, 2, 3};
for (int n : arr) {
System.out.println(n);
}
int[] arr = {1, 2, 3};
{ // These extra braces are to limit scope; they do not affect the bytecode
int[] iter = arr;
int length = iter.length;
for (int i = 0; i < length; i++) {
int n = iter[i];
System.out.println(n);
}
}
While this doesn't work for primitives, it should be noted that converting an array to a List with Arrays.asList
does not impact performance in any significant way. The impact on both memory and performance is nearly immeasurable.
Arrays.asList
does not use a normal List implementation that is readily accessible as a class. It uses java.util.Arrays.ArrayList
, which is not the same as java.util.ArrayList
. It is a very thin wrapper around an array and cannot be resized. Looking at the source code for java.util.Arrays.ArrayList
, we can see that it's designed to be functionally equivalent to an array. There is almost no overhead. Note that I have omitted all but the most relevant code and added my own comments.
public class Arrays {
public static <T> List<T> asList(T... a) {
return new ArrayList<>(a);
}
private static class ArrayList<E> extends AbstractList<E> implements RandomAccess, java.io.Serializable {
private final E[] a;
ArrayList(E[] array) {
a = Objects.requireNonNull(array);
}
@Override
public int size() {
return a.length;
}
@Override
public E get(int index) {
return a[index];
}
@Override
public E set(int index, E element) {
E oldValue = a[index];
a[index] = element;
return oldValue;
}
}
}
The iterator is at java.util.AbstractList.Itr
. As far as iterators go, it's very simple; it just calls get()
until size()
is reached, much like a manual for loop would do. It's the simplest and usually most efficient implementation of an Iterator
for an array.
Again, Arrays.asList
does not create a java.util.ArrayList
. It's much more lightweight and suitable for obtaining an iterator with negligible overhead.
As others have noted, Arrays.asList
can't be used on primitive arrays. Java 8 introduces several new technologies for dealing with collections of data, several of which could be used to extract simple and relatively efficient iterators from arrays. Note that if you use generics, you're always going to have the boxing-unboxing problem: you'll need to convert from int to Integer and then back to int. While boxing/unboxing is usually negligible, it does have an O(1) performance impact in this case and could lead to problems with very large arrays or on computers with very limited resources (i.e., SoC).
My personal favorite for any sort of array casting/boxing operation in Java 8 is the new stream API. For example:
int[] arr = {1, 2, 3};
Iterator<Integer> iterator = Arrays.stream(arr).mapToObj(Integer::valueOf).iterator();
The streams API also offers constructs for avoiding the boxing issue in the first place, but this requires abandoning iterators in favor of streams. There are dedicated stream types for int, long, and double (IntStream, LongStream, and DoubleStream, respectively).
int[] arr = {1, 2, 3};
IntStream stream = Arrays.stream(arr);
stream.forEach(System.out::println);
Interestingly, Java 8 also adds java.util.PrimitiveIterator
. This provides the best of both worlds: compatibility with Iterator<T>
via boxing along with methods to avoid boxing. PrimitiveIterator has three built-in interfaces that extend it: OfInt, OfLong, and OfDouble. All three will box if next()
is called but can also return primitives via methods such as nextInt()
. Newer code designed for Java 8 should avoid using next()
unless boxing is absolutely necessary.
int[] arr = {1, 2, 3};
PrimitiveIterator.OfInt iterator = Arrays.stream(arr);
// You can use it as an Iterator<Integer> without casting:
Iterator<Integer> example = iterator;
// You can obtain primitives while iterating without ever boxing/unboxing:
while (iterator.hasNext()) {
// Would result in boxing + unboxing:
//int n = iterator.next();
// No boxing/unboxing:
int n = iterator.nextInt();
System.out.println(n);
}
If you're not yet on Java 8, sadly your simplest option is a lot less concise and is almost certainly going to involve boxing:
final int[] arr = {1, 2, 3};
Iterator<Integer> iterator = new Iterator<Integer>() {
int i = 0;
@Override
public boolean hasNext() {
return i < arr.length;
}
@Override
public Integer next() {
if (!hasNext()) {
throw new NoSuchElementException();
}
return arr[i++];
}
};
Or if you want to create something more reusable:
public final class IntIterator implements Iterator<Integer> {
private final int[] arr;
private int i = 0;
public IntIterator(int[] arr) {
this.arr = arr;
}
@Override
public boolean hasNext() {
return i < arr.length;
}
@Override
public Integer next() {
if (!hasNext()) {
throw new NoSuchElementException();
}
return arr[i++];
}
}
You could get around the boxing issue here by adding your own methods for obtaining primitives, but it would only work with your own internal code.
No, it is not. However, that doesn't mean wrapping it in a list is going to give you worse performance, provided you use something lightweight such as Arrays.asList
.
Based on @givanse's answer, this is how you could do it with classes
:
class Swipe {
constructor(element) {
this.xDown = null;
this.yDown = null;
this.element = typeof(element) === 'string' ? document.querySelector(element) : element;
this.element.addEventListener('touchstart', function(evt) {
this.xDown = evt.touches[0].clientX;
this.yDown = evt.touches[0].clientY;
}.bind(this), false);
}
onLeft(callback) {
this.onLeft = callback;
return this;
}
onRight(callback) {
this.onRight = callback;
return this;
}
onUp(callback) {
this.onUp = callback;
return this;
}
onDown(callback) {
this.onDown = callback;
return this;
}
handleTouchMove(evt) {
if ( ! this.xDown || ! this.yDown ) {
return;
}
var xUp = evt.touches[0].clientX;
var yUp = evt.touches[0].clientY;
this.xDiff = this.xDown - xUp;
this.yDiff = this.yDown - yUp;
if ( Math.abs( this.xDiff ) > Math.abs( this.yDiff ) ) { // Most significant.
if ( this.xDiff > 0 ) {
this.onLeft();
} else {
this.onRight();
}
} else {
if ( this.yDiff > 0 ) {
this.onUp();
} else {
this.onDown();
}
}
// Reset values.
this.xDown = null;
this.yDown = null;
}
run() {
this.element.addEventListener('touchmove', function(evt) {
this.handleTouchMove(evt).bind(this);
}.bind(this), false);
}
}
You can than use it like this:
// Use class to get element by string.
var swiper = new Swipe('#my-element');
swiper.onLeft(function() { alert('You swiped left.') });
swiper.run();
// Get the element yourself.
var swiper = new Swipe(document.getElementById('#my-element'));
swiper.onLeft(function() { alert('You swiped left.') });
swiper.run();
// One-liner.
(new Swipe('#my-element')).onLeft(function() { alert('You swiped left.') }).run();
Do you need something like this(without time)?
public static Integer toJulianDate(Date pDate) {
if (pDate == null) {
return null;
}
Calendar lCal = Calendar.getInstance();
lCal.setTime(pDate);
int lYear = lCal.get(Calendar.YEAR);
int lMonth = lCal.get(Calendar.MONTH) + 1;
int lDay = lCal.get(Calendar.DATE);
int a = (14 - lMonth) / 12;
int y = lYear + 4800 - a;
int m = lMonth + 12 * a - 3;
return lDay + (153 * m + 2) / 5 + 365 * y + y / 4 - y / 100 + y / 400 - 32045;
}
The argument is of length zero takes places when you get an output as an integer of length 0 and not a NULL output.i.e., integer(0).
You can further verify my point by finding the class of your output-
>class(output)
"integer"
For those who are still facing this issue try adding:
libxml_use_internal_errors(true);
before the loadHtml
call and add
libxml_use_internal_errors(false);
after the call.
This solved it for me.
Now as an extension method:
public static class LinqExt
{
public static IEnumerable<TResult> LeftOuterJoin<TLeft, TRight, TKey, TResult>(this IEnumerable<TLeft> left, IEnumerable<TRight> right, Func<TLeft, TKey> leftKey, Func<TRight, TKey> rightKey,
Func<TLeft, TRight, TResult> result)
{
return left.GroupJoin(right, leftKey, rightKey, (l, r) => new { l, r })
.SelectMany(
o => o.r.DefaultIfEmpty(),
(l, r) => new { lft= l.l, rght = r })
.Select(o => result.Invoke(o.lft, o.rght));
}
}
Use like you would normally use join:
var contents = list.LeftOuterJoin(list2,
l => l.country,
r => r.name,
(l, r) => new { count = l.Count(), l.country, l.reason, r.people })
Hope this saves you some time.
I looked at Nate Barr's answer above, which you seemed to like. It doesn't seem very different from the simpler
html {background-color: grey}
I thought that Structs was intended as a Data Structure (like a multi-data type array of information) and classes was inteded for Code Packaging (like collections of subroutines & functions)..

After a lot of research, right now this is the most updated compiled library for Android that I found:

It may be better to use REAL type, to save storage space.
Quote from 1.2 section of Datatypes In SQLite Version 3
SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values
CREATE TABLE test (
id INTEGER PRIMARY KEY AUTOINCREMENT,
t REAL DEFAULT (datetime('now', 'localtime'))
);
see column-constraint .
And insert a row without providing any value.
INSERT INTO "test" DEFAULT VALUES;
I solved mine by changing DATE
to DATETIME
It's not a good coding to put PHP code into CSS
body
{
background-image:url('bg.png');
}
that's it
The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.
HTML
<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
Nothing here
</div>
You can use CSS to style the main section of the dialog but not the title
.custom-ui-widget-header-warning {
background: #EBCCCC;
font-size: 1em;
}
You need some JS to style the title
$(function() {
$("#nonmodal1").dialog({
minWidth: 400,
minHeight: 'auto',
autoOpen: false,
dialogClass: 'custom-ui-widget-header-warning',
position: {
my: 'center',
at: 'left'
}
});
$("#dialog1").click(function() {
if ($("#nonmodal1").dialog("isOpen") === true) {
$("#nonmodal1").dialog("close");
} else {
$("#nonmodal1").dialog("open").prev().css('background','#D9534F');
}
});
});
The example only shows simple styling (background) but you can make it as complex as you wish.
You can see it in action here:
var floatValue = 10.23
var intValue = Int(floatValue)
This is enough to convert from float
to Int
element.style
has a setProperty
method that can take the priority as a third parameter:
element.style.setProperty("display", "inline", "important")
It didn't work in old IEs but it should be fine in current browsers.
Swift 3 syntax:

Do you specify a user name and password to log on? What exactly is your complete command line?
If you're running on your own box, you can either specify a username/password, or use the -E

If you're interested, there's a well-established package out there that you can add to your Codeigniter project that will handle this:
https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc/
Modular Extensions makes the CodeIgniter PHP framework modular. Modules are groups of independent components, typically model, controller and view, arranged in an application modules sub-directory, that can be dropped into other CodeIgniter applications.
OK, so the big change is that now you'd be using a modular structure - but to me this is desirable. I have used CI for about 3 years now, and can't imagine life without Modular Extensions.
Now, here's the part that deals with directly calling controllers for rendering view partials:
// Using a Module as a view partial from within a view is as easy as writing:
<?php echo modules::run('module/controller/method', $param1, $params2); ?>
That's all there is to it. I typically use this for loading little "widgets" like:
Typically I build a "widget" controller for each module and use it only for this purpose.
Your question was also one of my first questions when I started with Codeigniter. I hope this helps you out, even though it may be a bit more than you were looking for. I've been using MX ever since and haven't looked back.
Make sure to read the docs and check out the multitude of information regarding this package on the Codeigniter forums. Enjoy!
If you are using a simulator in Android Studio on Mac you can go to View -> Tool Windows -> Device File Explorer
. Here you can use a finder-like structure.
You need to enable deep object dirty checking. By default angular only checks the reference of the top level variable that you watch.
App.directive('d3Visualization', function() {
return {
restrict: 'E',
scope: {
val: '='
},
link: function(scope, element, attrs) {
scope.$watch('val', function(newValue, oldValue) {
if (newValue)
console.log("I see a data change!");
}, true);
}
}
});
see Scope. The third parameter of the $watch function enables deep dirty checking if it's set to true.
Take note that deep dirty checking is expensive. So if you just need to watch the children array instead of the whole data
variable the watch the variable directly.
scope.$watch('val.children', function(newValue, oldValue) {}, true);
version 1.2.x introduced $watchCollection
Shallow watches the properties of an object and fires whenever any of the properties change (for arrays, this implies watching the array items; for object maps, this implies watching the properties)
scope.$watchCollection('val.children', function(newValue, oldValue) {});
The error says that a warning was treated as an error, therefore your problem is a warning message! The object file is then not created because there was an error. So you need to check your warnings and fix them.
In case you don't know how to find them: Open the Error List
(View
> Error List
) and click on Warning
.
If value
is unindexed, both result in a table-scan. The performance difference in this scenario will be negligible.
If value
is indexed, as Daniel points out in his comment, the =
will result in an index lookup which is O(log N) performance. The LIKE will (most likely - depending on how selective it is) result in a partial scan of the index >= 'abc'
and < 'abd'
which will require more effort than the =
.
Note that I'm talking SQL Server here - not all DBMSs will be nice with LIKE.
var img = $('<img />', {
id: 'Myid',
src: 'MySrc.gif',
alt: 'MyAlt'
});
img.appendTo($('#YourDiv'));
where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS')
should work.
You should seriously consider dhiller's answer:
new ArrayList(set)
(or a new LinkedList(set)
, whatever).I think that the solution you posted with the NoDuplicatesList
has some issues, mostly with the contains()
method, plus your class does not handle checking for duplicates in the Collection passed to your addAll()
method.
I finished my time alert with a unwanted effect.... Browsers add stuff to windows. My script is an aptated one and I will show after the following text.
I found a CSS script for popups, which doesn't have unwanted browser stuff. This was written by Prakash:- https://codepen.io/imprakash/pen/GgNMXO. This script I will show after the following text.
This CSS script above looks professional and is alot more tidy. This button could be a clickable company logo image. By suppressing this button/image from running a function, this means you can run this function from inside javascript or call it with CSS, without it being run by clicking it.
This popup alert stays inside the window that popped it up. So if you are a multi-tasker you won't have trouble knowing what alert goes with what window.
The statements above are valid ones.... (Please allow). How these are achieved will be down to experimentation, as my knowledge of CSS is limited at the moment, but I learn fast.
CSS menus/DHTML use mouseover(valid statement).
I have a CSS menu script of my own which is adapted from 'Javascript for dummies' that pops up a menu alert. This works, but text size is limited. This hides under the top window banner. This could be set to be timed alert. This isn't great, but I will show this after the following text.
The Prakash script above I feel could be the answer if you can adapt it.
Scripts that follow:- My adapted timed window alert, Prakash's CSS popup script, my timed menu alert.

See this solution. It can be solved with a window scroll event firing one time only.
Actually, you should use the translate directive for such stuff instead.
<h1 translate="{{pageTitle}}"></h1>
The directive takes care of asynchronous execution and is also clever enough to unwatch translation ids on the scope if the translation has no dynamic values.
However, if there's no way around and you really have to use $translate
service in the controller, you should wrap the call in a $translateChangeSuccess
event using $rootScope
in combination with $translate.instant()
like this:
.controller('foo', function ($rootScope, $scope, $translate) {
$rootScope.$on('$translateChangeSuccess', function () {
$scope.pageTitle = $translate.instant('PAGE.TITLE');
});
})
So why $rootScope
and not $scope
? The reason for that is, that in angular-translate's events are $emit
ed on $rootScope
rather than $broadcast
ed on $scope
because we don't need to broadcast through the entire scope hierarchy.
Why $translate.instant()
and not just async $translate()
? When $translateChangeSuccess
event is fired, it is sure that the needed translation data is there and no asynchronous execution is happening (for example asynchronous loader execution), therefore we can just use $translate.instant()
which is synchronous and just assumes that translations are available.
Since version 2.8.0 there is also $translate.onReady()
, which returns a promise that is resolved as soon as translations are ready. See the changelog.
A great resource is iosfonts.com, which says that the name for that font is HelveticaNeue-UltraLight
. So you'd use this code:
label.font = UIFont(name: "HelveticaNeue-UltraLight", size: 30)
If the system can't find the font, it defaults to a 'normal' font - I think it's something like 11-point Helvetica. This can be quite confusing, always check your font names.
In my case, I was mistaken the function parameters, which are:
context.drawImage(image, left, top);
context.drawImage(image, left, top, width, height);
If you expect them to be
context.drawImage(image, width, height);
you will place the image just outside the canvas with the same effects as described in the question.
Two things. First, you must base64 decode the mykey.pem
file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey
ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec
, which is based on the SubjectPublicKeyInfo
ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.
import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;
// ...
String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);
I resolved a similar issue by simply restarting Visual Studio with admin rights.
The problem was because it couldn't open one project related to Sharepoint without elevated access.
Use

rowMeans
is nice, but if you are still trying to wrap your head around the apply
family of functions, this is a good opprotunity to begin understanding it.
DF['Mean'] <- apply(DF[,2:4], 1, mean)
Notice I'm doing a slightly different assignment than the first example. This approach makes it easier to incorporate it into for loops.
You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'
The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.
npm install
now supports thisnpm install --save ../path/to/mymodule
For this to work mymodule
must be configured as a module with its own package.json
. See Creating NodeJS modules.
As of npm 2.0, local dependencies are supported natively. See danilopopeye's answer to a similar question. I've copied his response here as this question ranks very high in web search results.
This feature was implemented in the version 2.0.0 of npm. For example:
{ "name": "baz", "dependencies": { "bar": "file:../foo/bar" } }
Any of the following paths are also valid:
../foo/bar ~/foo/bar ./foo/bar /foo/bar
Since npm install
copies mymodule
into node_modules
, changes in mymodule
's source will not automatically be seen by the dependent project.
There are two ways to update the dependent project with
Update the version of mymodule
and then use npm update
: As you can see above, the package.json
"dependencies" entry does not include a version specifier as you would see for normal dependencies. Instead, for local dependencies, npm update
just tries to make sure the latest version is installed, as determined by mymodule
's package.json
. See chriskelly's answer to this specific problem.
Reinstall using npm install
. This will install whatever is at mymodule
's source path, even if it is older, or has an alternate branch checked out, whatever.

Create a HttpRequestMessage
, set the Method to GET
, set your headers and then use SendAsync
instead of GetAsync
.
var client = new HttpClient();
var request = new HttpRequestMessage() {
RequestUri = new Uri("http://www.someURI.com"),
Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
.ContinueWith((taskwithmsg) =>
{
var response = taskwithmsg.Result;
var jsonTask = response.Content.ReadAsAsync<JsonObject>();
jsonTask.Wait();
var jsonObject = jsonTask.Result;
});
task.Wait();
It's better also to separate your logic in another method, or maybe in another class.

I found a solution to fix this.
Edit your /etc/phpmyadmin/config.inc.php file.
Find:
if (!empty($dbport) || $dbserver != 'localhost') {
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['port'] = $dbport;
}
Add after:
$cfg['Servers'][$i]['pmadb'] = null; // Apurba
Restart your apache service and try. Hope it helps. Thanks.
Spinner returns you the integer value for the array. You have to retrieve the string value based of the index.
Spinner MySpinner = (Spinner)findViewById(R.id.spinner);
Integer indexValue = MySpinner.getSelectedItemPosition();
Your route isn't ok, it should be like this (with ':')
app.get('/documents/:format/:type', function (req, res) {
var format = req.params.format,
type = req.params.type;
});
Also you cannot interchange parameter order unfortunately.
For more information on req.params
(and req.query
) check out the api reference here.
Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:
runas /user:(ComputerName)\(local admin) powershell.exe
So a basic example would be:
runas /user:MyLaptop\[email protected] powershell.exe
You can find more information on this subject in Runas.
However, you could also do one more thing :
then your system will execute the elevated powershell.
Before writing this off as impossible I suggest you look at the source code of the lsof command.
There may be restrictions but lsof seems capable of determining the file descriptor and file name. This information exists in the /proc filesystem so it should be possible to get at from your program.
ping -n 11 -w 1000 127.0.0.1 > nul
Update
Beginner's mistake. Ping doesn't wait 1000 ms before or after an request, but inbetween requests. So to wait 10 seconds, you'll have to do 11 pings to have 10 'gaps' of a second inbetween.

Don't do: mkdir -m 777 -p a/b/c
since that will only set permission 777
on the last directory, c; a and b will be created with the default permission from your umask.
Instead to create any new directories with permission 777
, run mkdir -p
in a subshell where you override the umask:
(umask u=rwx,g=rwx,o=rwx && mkdir -p a/b/c)
Note that this won't change the permissions if any of a, b and c already exist though.
SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_catalog = 'database_name' -- the database
AND table_name = 'table_name'
You could use predefined utility type Record<Keys, Type>
:
const obj: Record<string, string> = {
property: "value",
};
It allows to specify keys for your object literal:
type Keys = "prop1" | "prop2"
const obj: Record<Keys, string> = {
prop1: "Hello",
prop2: "Aloha",
something: "anything" // TS Error: Type '{ prop1: string; prop2: string; something: string; }' is not assignable to type 'Record<Keys, string>'.
// Object literal may only specify known properties, and 'something' does not exist in type 'Record<Keys, string>'.
};
And a type for the property value:
type Keys = "prop1" | "prop2"
type Value = "Hello" | "Aloha"
const obj1: Record<Keys, Value> = {
prop1: "Hello",
prop2: "Hey", // TS Error: Type '"Hey"' is not assignable to type 'Value'.
};
In my case I had to start a list of exclude extensions from the second line because xcopy ignored the first line.
here are some working and tested methods;
using Scanner
package io;
import java.io.File;
import java.util.Scanner;
public class ReadFromFileUsingScanner {
public static void main(String[] args) throws Exception {
File file=new File("C:\\Users\\pankaj\\Desktop\\test.java");
Scanner sc=new Scanner(file);
while(sc.hasNextLine()){
System.out.println(sc.nextLine());
}
}
}
Here's another way to read entire file (without loop) using Scanner
class
package io;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class ReadingEntireFileWithoutLoop {
public static void main(String[] args) throws FileNotFoundException {
File file=new File("C:\\Users\\pankaj\\Desktop\\test.java");
Scanner sc=new Scanner(file);
sc.useDelimiter("\\Z");
System.out.println(sc.next());
}
}
using BufferedReader
package io;
import java.io.*;
public class ReadFromFile2 {
public static void main(String[] args)throws Exception {
File file=new File("C:\\Users\\pankaj\\Desktop\\test.java");
BufferedReader br=new BufferedReader(new FileReader(file));
String st;
while((st=br.readLine())!=null){
System.out.println(st);
}
}
}
using FileReader
package io;
import java.io.*;
public class ReadingFromFile {
public static void main(String[] args) throws Exception {
FileReader fr=new FileReader("C:\\Users\\pankaj\\Desktop\\test.java");
int i;
while((i=fr.read())!=-1){
System.out.print((char) i);
}
}
}

newDate.set(year, monthOfYear, dayOfMonth);
activitydate.setText(dateFormatter.format(newDate.getTime()));
}
}, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));

Check out this neat table that shows the differences in syntax between 2 and 3 when it comes to this.
I worked on this issue for a few days. Installed all packages, modified web.config and still had the same problem. I finally removed
<assemblies>
<add assembly="Microsoft.ReportViewer.Common, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</assemblies>
from the web.config and it worked. No exactly sure why it didn't work with the tags in the web.config file. My guess there is a conflict with the GAC and the BIN folder.
Here is my web.config file:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
<httpHandlers>
<add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</httpHandlers>

All the above mentioned answers will almost fullfill the purpose. However, You need to drop the temp table after all the operation on it. You can follow-
INSERT INTO #TempTable (ID, Date, Name) SELECT id, date, name FROM physical_table;
IF OBJECT_ID('tempdb.dbo.#TempTable') IS NOT NULL DROP TABLE #TempTable;
For single css property
ng-style="1==1 && {'color':'red'}"
For multiple css properties below can be referred
ng-style="1==1 && {'color':'red','font-style': 'italic'}"
Replace 1==1 with your condition expression
First you must test the query list size; here a example:
long count;
if (query.list().size() > 0)
count=(long) criteria.list().get(0);
else
count=0;
return count;
I think what you need is the below prototype
$(element).on('input',function(){code})
Finding the first occurrence
There's a recipe for that in itertools
:
def first_true(iterable, default=False, pred=None):
"""Returns the first true value in the iterable.
If no true value is found, returns *default*
If *pred* is not None, returns the first item
for which pred(item) is true.
"""
# first_true([a,b,c], x) --> a or b or c or x
# first_true([a,b], x, f) --> a if f(a) else b if f(b) else x
return next(filter(pred, iterable), default)
For example, the following code finds the first odd number in a list:
>>> first_true([2,3,4,5], None, lambda x: x%2==1)
3
For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.
The extern
declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern
in a header file like:
extern struct a myAValue;
Then, in one source file, define the actual variable:
struct a myAValue;
If you forget to do this or accidentally define it in two source files, the linker will let you know about this.
You can use the Attribute.IsDefined method
https://msdn.microsoft.com/en-us/library/system.attribute.isdefined(v=vs.110).aspx
if(Attribute.IsDefined(YourProperty,typeof(YourAttribute)))
{
//Conditional execution...
}
You could provide the property you're specifically looking for or you could iterate through all of them using reflection, something like:
PropertyInfo[] props = typeof(YourClass).GetProperties();
If you are using C# you should use Environment.NewLine
, which accordingly to MSDN it is:
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.
There is also this:
select m from table where not regexp_like(m, '^[0-9]\d+$')
which selects the rows that contains characters from the column you want (which is m in the example but you can change).
Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.
{{ word|striptags('<b>,<a>,<pre>')|raw }}
if you want to allow multiple tags
The cleanest way to work with it. Assuming your table is a list of integers called "dbo.tvp_Int" (Customize for your own table type)
Create this extension method...
public static void AddWithValue_Tvp_Int(this SqlParameterCollection paramCollection, string parameterName, List<int> data)
{
if(paramCollection != null)
{
var p = paramCollection.Add(parameterName, SqlDbType.Structured);
p.TypeName = "dbo.tvp_Int";
DataTable _dt = new DataTable() {Columns = {"Value"}};
data.ForEach(value => _dt.Rows.Add(value));
p.Value = _dt;
}
}
Now you can add a table valued parameter in one line anywhere simply by doing this:
cmd.Parameters.AddWithValueFor_Tvp_Int("@IDValues", listOfIds);
There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.
Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.
For Mobile Safari There is a Browser fix. you need to add -webkit-box for iOS devices.
Ex.
display: flex;
display: -webkit-box;
flex-direction: column;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-webkit-flex-direction: column;
align-items: stretch;
if you're using align-items: stretch;
property for parent element, remove the height : 100%
from the child element.
set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
Using simple html,
<div>
<object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
</object>
</div>
Or jquery,
<script>
$("#mydiv")
.html('<object data="http://your-website-domain"/>');
</script>
Use an empty element sized for the content as the background, and position the content over the blurred element.
#dialog_base{
background:white;
background:rgba(255,255,255,0.8);
position: absolute;
top: 40%;
left: 50%;
z-index: 50;
margin-left: -200px;
height: 200px;
width: 400px;
filter:blur(4px);
-o-filter:blur(4px);
-ms-filter:blur(4px);
-moz-filter:blur(4px);
-webkit-filter:blur(4px);
}
#dialog_content{
background: transparent;
position: absolute;
top: 40%;
left: 50%;
margin-left -200px;
overflow: hidden;
z-index: 51;
}
The background element can be inside of the content element, but not the other way around.
<div id='dialog_base'></div>
<div id='dialog_content'>
Some Content
<!-- Alternatively with z-index: <div id='dialog_base'></div> -->
</div>
This is not easy if the content is not always consistently sized, but it works.
heres a jquery plugin to do that
(function($) {
$.fn.onEnter = function(func) {
this.bind('keypress', function(e) {
if (e.keyCode == 13) func.apply(this, [e]);
});
return this;
};
})(jQuery);
to use it, include the code and set it up like this:
$( function () {
console.log($("input"));
$("input").onEnter( function() {
$(this).val("Enter key pressed");
});
});
I'm an early adopter and implemented a mid-large single page application using the Facebook Flux library.
As I'm a little late to the conversation I'll just point out that despite my best hopes Facebook seem to consider their Flux implementation to be a proof of concept and it has never received the attention it deserves.
I'd encourage you to play with it, as it exposes more of the inner working of the Flux architecture which is quite educational, but at the same time it does not provide many of the benefits that libraries like Redux provide (which aren't that important for small projects, but become very valuable for bigger ones).
We have decided that moving forward we will be moving to Redux and I suggest you do the same ;)
Just to add something I was missing from all the answers - even if it seems to be silly and obvious as soon as you know:
The file has to be named "App.config" or "app.config" and can be located in your project at the same level as e.g. Program.cs.
I do not know if other locations are possible, other names (like application.conf, as suggested in the ODP.net documentation) did not work for me.
PS. I started with Visual Studio Code and created a new project with "dotnet new". No configuration file is created in this case, I am sure there are other cases. PPS. You may need to add a nuget package to be able to read the config file, in case of .NET CORE it would be "dotnet add package System.Configuration.ConfigurationManager --version 4.5.0"
VBA stands for Visual Basic For Applications and its a Visual Basic implementation intended to be used in the Office Suite.
The difference between them is that VBA is embedded inside Office documents (its an Office feature). VB is the ide/language for developing applications.
Find out the web server user
open up terminal and type
lsof -i tcp:80
This will show you the user of the web server process Here is an example from a raspberry pi running debian:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
apache2 7478 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
apache2 7664 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
apache2 7794 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
The user is www-data
If you give ownership of the web files to the web server:
chown www-data:www-data -R /opt/lamp/htdocs
And chmod 755 for good measure:
chmod 755 -R /opt/lamp/htdocs
Let me know how you go, maybe you need to use 'sudo' before the command, i.e.
sudo chown www-data:www-data -R /opt/lamp/htdocs
if it doesn't work, please give us the output of:
ls -al /opt/lamp/htdocs
simply use..
location.reload(true/false);
If false, the page will be reloaded from cache, else from the server.
Have a look and see if the the JDK is at:
Library/Java/JavaVirtualMachines/ Or /System/Library/Java/JavaVirtualMachines/
Check this earlier SO post: JDK on OSX 10.7 Lion
This explanation might help: http://code.google.com/p/android/issues/detail?id=8488#c80
"Fast Tips:
1) NEVER call System.gc() yourself. This has been propagated as a fix here, and it doesn't work. Do not do it. If you noticed in my explanation, before getting an OutOfMemoryError, the JVM already runs a garbage collection so there is no reason to do one again (its slowing your program down). Doing one at the end of your activity is just covering up the problem. It may causes the bitmap to be put on the finalizer queue faster, but there is no reason you couldn't have simply called recycle on each bitmap instead.
2) Always call recycle() on bitmaps you don't need anymore. At the very least, in the onDestroy of your activity go through and recycle all the bitmaps you were using. Also, if you want the bitmap instances to be collected from the dalvik heap faster, it doesn't hurt to clear any references to the bitmap.
3) Calling recycle() and then System.gc() still might not remove the bitmap from the Dalvik heap. DO NOT BE CONCERNED about this. recycle() did its job and freed the native memory, it will just take some time to go through the steps I outlined earlier to actually remove the bitmap from the Dalvik heap. This is NOT a big deal because the large chunk of native memory is already free!
4) Always assume there is a bug in the framework last. Dalvik is doing exactly what its supposed to do. It may not be what you expect or what you want, but its how it works. "
Im using jQuery Lazy. It took me about 10 minutes to test out and an hour or two to add to most of the image links on one of my websites (CollegeCarePackages.com). I have NO (none/zero) relationship of any kind to the dev, but it saved me a lot of time and basically helped improve our bounce rate for mobile users and I appreciate it.

You may need to check who the actual owner of the stored procedure is. If it is a specific different user then that could be why you can't access it.
In addition to the suggestions in this thread, I wanted to mention that if you need to return dot files as well (.gitignore, etc), with Dir.glob you would need to include a flag as so:
Dir.glob("/path/to/dir/*", File::FNM_DOTMATCH)
By default, Dir.entries includes dot files, as well as current a parent directories.
For anyone interested, I was curious how the answers here compared to each other in execution time, here was the results against deeply nested hierarchy. The first three results are non-recursive:
user system total real
Dir[*]: (34900 files stepped over 100 iterations)
0.110729 0.139060 0.249789 ( 0.249961)
Dir.glob(*): (34900 files stepped over 100 iterations)
0.112104 0.142498 0.254602 ( 0.254902)
Dir.entries(): (35600 files stepped over 100 iterations)
0.142441 0.149306 0.291747 ( 0.291998)
Dir[**/*]: (2211600 files stepped over 100 iterations)
9.399860 15.802976 25.202836 ( 25.250166)
Dir.glob(**/*): (2211600 files stepped over 100 iterations)
9.335318 15.657782 24.993100 ( 25.006243)
Dir.entries() recursive walk: (2705500 files stepped over 100 iterations)
14.653018 18.602017 33.255035 ( 33.268056)
Dir.glob(**/*, File::FNM_DOTMATCH): (2705500 files stepped over 100 iterations)
12.178823 19.577409 31.756232 ( 31.767093)
These were generated with the following benchmarking script:
require 'benchmark'
base_dir = "/path/to/dir/"
n = 100
Benchmark.bm do |x|
x.report("Dir[*]:") do
i = 0
n.times do
i = i + Dir["#{base_dir}*"].select {|f| !File.directory? f}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir.glob(*):") do
i = 0
n.times do
i = i + Dir.glob("#{base_dir}/*").select {|f| !File.directory? f}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir.entries():") do
i = 0
n.times do
i = i + Dir.entries(base_dir).select {|f| !File.directory? File.join(base_dir, f)}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir[**/*]:") do
i = 0
n.times do
i = i + Dir["#{base_dir}**/*"].select {|f| !File.directory? f}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir.glob(**/*):") do
i = 0
n.times do
i = i + Dir.glob("#{base_dir}**/*").select {|f| !File.directory? f}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir.entries() recursive walk:") do
i = 0
n.times do
def walk_dir(dir, result)
Dir.entries(dir).each do |file|
next if file == ".." || file == "."
path = File.join(dir, file)
if Dir.exist?(path)
walk_dir(path, result)
else
result << file
end
end
end
result = Array.new
walk_dir(base_dir, result)
i = i + result.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
x.report("Dir.glob(**/*, File::FNM_DOTMATCH):") do
i = 0
n.times do
i = i + Dir.glob("#{base_dir}**/*", File::FNM_DOTMATCH).select {|f| !File.directory? f}.length
end
puts " (#{i} files stepped over #{n} iterations)"
end
end
The differences in file counts are due to Dir.entries
including hidden files by default. Dir.entries
ended up taking a bit longer in this case due to needing to rebuild the absolute path of the file to determine if a file was a directory, but even without that it was still taking consistently longer than the other options in the recursive case. This was all using ruby 2.5.1 on OSX.
Keep the json file in Assets (parallel to app dir) directory
Note that if you would have generated with ng new YourAppname- this assets directory exists same line with 'app' directory, and services should be child directory of app directory. May look like as below:
::app/services/myservice.ts
getOrderSummary(): Observable {
// get users from api
return this.http.get('assets/ordersummary.json')//, options)
.map((response: Response) => {
console.log("mock data" + response.json());
return response.json();
}
)
.catch(this.handleError);
}
Please try with the below code snippet.

I have implemented same thing with different way.
From the documentation for strtotime()
:
Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.
In your date string, you have 12-16-2013
. 16
isn't a valid month, and hence strtotime()
returns false
.
Since you can't use DateTime class, you could manually replace the -
with /
using str_replace()
to convert the date string into a format that strtotime()
understands:
$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16
I've backported the three Material Design progress drawables to Android 4.0, which can be used as a drop-in replacement for regular ProgressBar
, with exactly the same appearance.
These drawables also backported the tinting APIs (and RTL support), and uses ?colorControlActivated
as the default tint. A MaterialProgressBar
widget which extends ProgressBar
has also been introduced for convenience.
DreaminginCodeZH/MaterialProgressBar
This project has also been adopted by afollestad/material-dialogs for progress dialog.
On Android 4.4.4:
On Android 5.1.1:
Simple, use absolute positioning, and instead of specifying a top and a left, specify a top and a right!
For example:
#logo_image {
width:80px;
height:80px;
top:10px;
right:10px;
z-index: 3;
position:absolute;
}
Thanks to duncan answer, I end up with this:
marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())
You can use int
and set the base to 2
(for binary):
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> int(binary, 2)
25
>>>
However, if you cannot use int
like that, then you could always do this:
binary = raw_input('enter a number: ')
decimal = 0
for digit in binary:
decimal = decimal*2 + int(digit)
print decimal
Below is a demonstration:
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> decimal = 0
>>> for digit in binary:
... decimal = decimal*2 + int(digit)
...
>>> print decimal
25
>>>
To map a composite key, you can use the EmbeddedId
or the IdClass
annotations. I know this question is not strictly about JPA but the rules defined by the specification also applies. So here they are:
2.1.4 Primary Keys and Entity Identity
...
A composite primary key must correspond to either a single persistent field or property or to a set of such fields or properties as described below. A primary key class must be defined to represent a composite primary key. Composite primary keys typically arise when mapping from legacy databases when the database key is comprised of several columns. The
EmbeddedId
andIdClass
annotations are used to denote composite primary keys. See sections 9.1.14 and 9.1.15....
The following rules apply for composite primary keys:
- The primary key class must be public and must have a public no-arg constructor.
- If property-based access is used, the properties of the primary key class must be public or protected.
- The primary key class must be
serializable
.- The primary key class must define
equals
andhashCode
methods. The semantics of value equality for these methods must be consistent with the database equality for the database types to which the key is mapped.- A composite primary key must either be represented and mapped as an embeddable class (see Section 9.1.14, “EmbeddedId Annotation”) or must be represented and mapped to multiple fields or properties of the entity class (see Section 9.1.15, “IdClass Annotation”).
- If the composite primary key class is mapped to multiple fields or properties of the entity class, the names of primary key fields or properties in the primary key class and those of the entity class must correspond and their types must be the same.
IdClass
The class for the composite primary key could look like (could be a static inner class):
public class TimePK implements Serializable {
protected Integer levelStation;
protected Integer confPathID;
public TimePK() {}
public TimePK(Integer levelStation, Integer confPathID) {
this.levelStation = levelStation;
this.confPathID = confPathID;
}
// equals, hashCode
}
And the entity:
@Entity
@IdClass(TimePK.class)
class Time implements Serializable {
@Id
private Integer levelStation;
@Id
private Integer confPathID;
private String src;
private String dst;
private Integer distance;
private Integer price;
// getters, setters
}
The IdClass
annotation maps multiple fields to the table PK.
EmbeddedId
The class for the composite primary key could look like (could be a static inner class):
@Embeddable
public class TimePK implements Serializable {
protected Integer levelStation;
protected Integer confPathID;
public TimePK() {}
public TimePK(Integer levelStation, Integer confPathID) {
this.levelStation = levelStation;
this.confPathID = confPathID;
}
// equals, hashCode
}
And the entity:
@Entity
class Time implements Serializable {
@EmbeddedId
private TimePK timePK;
private String src;
private String dst;
private Integer distance;
private Integer price;
//...
}
The @EmbeddedId
annotation maps a PK class to table PK.
@EmbeddedId
somehow communicates more clearly that the key is a composite key and IMO makes sense when the combined pk is either a meaningful entity itself or it reused in your code.@IdClass
is useful to specify that some combination of fields is unique but these do not have a special meaning.They also affect the way you write queries (making them more or less verbose):
with IdClass
select t.levelStation from Time t
with EmbeddedId
select t.timePK.levelStation from Time t
Data contract: It specifies that your entity class is ready for Serialization process.
Data members: It specifies that the particular field is part of the data contract and it can be serialized.
Alternatively you can use a "." instead of *, as this will take all the files in the working directory, include the folders and subfolders:
FROM ubuntu
COPY . /
RUN ls -la /
I got the solution for your requirement.
I'm also getting the same error in my eclipse Luna.
Go to Windows option -> select preference.
Than Select General -> Network Connection.
Than select the Active Provider as Manual.
Then restart the tomcat and run. It will work.
Hope it will help you.
Here is the code for upload to encode and save it to the MySQL
if (!isset($_GET["getfile"])) {
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br>";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);
$bin_string = file_get_contents($_FILES["file"]["name"]);
$hex_string = base64_encode($bin_string);
$mysqli = mysqli_init();
if (!$mysqli->real_connect('localhost', 'root', '', 'arihant')) {
die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
}
$mysqli->query("INSERT INTO upload(image) VALUES ('" . $hex_string . "')");
}
}
For showing the image use this
echo "<img src='data:image/jpeg;base64, $image' width=300>";
Using merge and renaming your t vector as tt (see the PS of Andrie) :
merge(tt,z,by="row.names",all.x=TRUE)[,-(5:8)]
Now if you would work with dataframes instead of matrices, this would even become a whole lot easier :
z <- as.data.frame(z)
tt <- as.data.frame(tt)
merge(tt,z["symbol"],by="row.names",all.x=TRUE)
To make your activity full screen do this:
// add following lines before setContentView
// to hide toolbar
if(getSupportActionBar()!=null)
getSupportActionBar().hide();
//to hide status bar
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
This will hide the toolbar and status bar.
But In some case, you may want to show status bar with a transparent background, in that case, do this:
// add following lines before setContentView
// to hide toolbar
if(getSupportActionBar()!=null)
getSupportActionBar().hide();
// to make status bar transparent
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
Some other alternate to hide toolbar instead of
getSupportActionBar().hide()
:
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
android:theme="@style/Theme.AppCompat.Light.NoActionBar"
For kotlin lovers, why not use extension functions:
For first case:
fun AppCompatActivity.makeItFullScreenStatusBarVisible(){
supportActionBar?.hide()
window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}
And call this before setContentView
:
makeItFullScreenStatusBarVisible()
For Second One:
fun AppCompatActivity.makeItFullScreenStatusBarHidden(){
supportActionBar?.hide()
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
}
And call it before setContentView
:
makeItFullScreenStatusBarHidden()
Rahul's answer gives me an error: You seem to be trying to send a WhatsApp message to a phone number that is not registered with WhatsApp..., even though I'm sending it to a registered WhatsApp number.
This, however works:
<li><a href="intent:0123456789#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end"><i class="fa fa-whatsapp"></i>+237 655 421 621</li>
Pass your comma-separated string into this function and it will return an array, and if a comma-separated string is not found then it will return null.
function splitTheString(CommaSepStr) {
var ResultArray = null;
// Check if the string is null or so.
if (CommaSepStr!= null) {
var SplitChars = ',';
// Check if the string has comma of not will go to else
if (CommaSepStr.indexOf(SplitChars) >= 0) {
ResultArray = CommaSepStr.split(SplitChars);
}
else {
// The string has only one value, and we can also check
// the length of the string or time and cross-check too.
ResultArray = [CommaSepStr];
}
}
return ResultArray;
}
This will serve the purpose. There is no need for any divs or paragraph. If you want the spaces between them to be specified, use margin-left or margin-right in the css classes.
<div style="width:500px;">
<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
</div>
When I want to access the application file version (what is set in Assembly Information -> File version), say to set a label's text to it on form load to display the version, I have just used
versionlabel.Text = "Version " + Application.ProductVersion;
This approach requires a reference to System.Windows.Forms
.
You can convert a number to ASCII in java. example converting a number 1 (base is 10) to ASCII.
char k = Character.forDigit(1, 10);
System.out.println("Character: " + k);
System.out.println("Character: " + ((int) k));
Output:
Character: 1
Character: 49
At least with Chrome, (I don't know about Firefox) You can drag the icon to the left of the URL in the browser to a folder location on your desktop and it will create a file that behaves as an internet shortcut.
I don't know if the file format is universal yet, however Chrome seems to know what to do with it.
The file produced is a .url
file and contains the following:
[InternetShortcut]
URL=http://www.accordingtothescriptures.org/prophecy/353prophecies.html
You can replace the URL with anything you'd like.
Technically, I would describe an interface as a set of ways (methods, properties, accessors... the vocabulary depends on the language you are using) to interact with an object. If an object supports/implements an interface, then you can use all of the ways specified in the interface to interact with this object.
Semantically, an interface could also contain conventions about what you may or may not do (e.g., the order in which you may call the methods) and about what, in return, you may assume about the state of the object given how you interacted so far.
Try the below, where strDate is your date in 'MM/dd/yyyy' format
var date = DateTime.Parse(strDate,new CultureInfo("en-US", true))
I had the same problem but solved it with a switch statement switch(a value you are switching on) { case 1: the code you want to happen; case 2: the code you want to happen; default: return a value }
I would try triming the number to see what you get:
select len(rtrim(ltrim(userid))) from audit
if that return the correct value then just do:
select convert(int, rtrim(ltrim(userid))) from audit
if that doesn't return the correct value then I would do a replace to remove the empty space:
select convert(int, replace(userid, char(0), '')) from audit
Here, if you want to control it through HTML: do like below Option 1:
<meta http-equiv="expires" content="Sun, 01 Jan 2014 00:00:00 GMT"/>
<meta http-equiv="pragma" content="no-cache" />
And if you want to control it through PHP: do it like below Option 2:
header('Expires: Sun, 01 Jan 2014 00:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');
AND Option 2 IS ALWAYS BETTER in order to avoid proxy based caching issue.
I guess I will start you off with the time complexity of a linked list:
Indexing---->O(n)
Inserting / Deleting at end---->O(1) or O(n)
Inserting / Deleting in middle--->O(1) with iterator O(n) with out
The time complexity for the Inserting at the end depends if you have the location of the last node, if you do, it would be O(1) other wise you will have to search through the linked list and the time complexity would jump to O(n).
Whereas @jbarrueta answer is perfect, in the 2.12 version of Jackson was introduced a new long-awaited type for the @JsonTypeInfo
annotation, DEDUCTION
.
It is useful for the cases when you have no way to change the incoming json or must not do so. I'd still recommend to use use = JsonTypeInfo.Id.NAME
, as the new way may throw an exception in complex cases when it has no way to determine which subtype to use.
Now you can simply write
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION)
@JsonSubTypes({
@JsonSubTypes.Type(Dog.class),
@JsonSubTypes.Type(Cat.class) }
)
public abstract class Animal {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
And it will produce {"name":"ruffus", "breed":"english shepherd"}
and {"name":"goya", "favoriteToy":"mice"}
Once again, it's safer to use NAME
if some of the fields may be not present, like breed
or favoriteToy
.
We have to dynamically set the attribute target="_blank" and it will open it in new tab.
document.getElementsByTagName("a")[0].setAttribute('target', '_blank')
document.getElementsByTagName("a")[0].click()
If you want to open in new window, get the href link and use window.open
var link = document.getElementsByTagName("a")[0].getAttribute("href");
window.open(url, "","height=500,width=500");
Don't provide the second parameter as _blank in the above.

$images_path = 'uploads/adsimages/';

I tried the ttfpatch tool and it didn't work form me. Internet Exploder 9 and 10 still complained.
I found this nice Git gist and it solved my issues. https://gist.github.com/stefanmaric/a5043c0998d9fc35483d
Just copy and paste the code in your css.
try :
sudo service nginx restart
Just use this acl cmd, next time the files inside var are created it will have the r/w/x permission for www-data user.
cd var
rm -rf *
cd ..
setfacl -d -m u:www-data:rwx var
Cmd explanation:
setfacl -> Set acl command
-d -> default behavior
-m -> modify
u:www-data: -> for user
rwx -> adding permissions
var -> on the folder
Simple to do:
header code...
Set objMyConn = New ADODB.Connection
Set objMyCmd = New ADODB.Command Set
objMyRecordset = New ADODB.Recordset
On Error GoTo ERRORHAND
Working code...
objMyConn.ConnectionString = ConnStr
objMyConn.Open
code....
'Copy Data FROM Excel'
objMyConn.BeginTrans <-- define transactions to possible be rolled back
For NewRows = 2 To Rows
objMyRecordset.AddNew
For NewColumns = 0 To Columns - 1
objMyRecordset.Fields(NewColumns).Value = ActiveSheet.Cells(NewRows, NewColumns + 1)
Next NewColumns objMyRecordset.Update Next NewRows
objMyConn.CommitTrans <- if success, commit them to DB
objMyConn.Close
ERRORHAND:
Success = False
objMyConn.RollbackTrans <-- here we roll back if error encountered somewhere
LogMessage = "ERROR writing database: " & Err.Description
...
You can create an unbuffered file and assign this file to sys.stdout.
import sys
myFile= open( "a.log", "w", 0 )
sys.stdout= myFile
You can't magically change the system-supplied stdout; since it's supplied to your python program by the OS.
CREATE TEMPORARY TABLE IF NOT EXISTS to_table_name AS (SELECT * FROM from_table_name)
Use beginUpdates
and endUpdates
to insert a new cell when the button clicked.
As @vadian said in comment,
begin/endUpdates
has no effect for a single insert/delete/move operation
First of all, append data in your tableview array
Yourarray.append([labeltext])
Then update your table and insert a new row
// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()
This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()
Swift 3.0
tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()
Objective-C
[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];
If you are using Kotlin, it becomes even easier to do by using core-ktx
, as it provides a domain-specific-language (DSL) for doing this:
val string: SpannedString = buildSpannedString {
bold {
append("foo")
}
append("bar")
}
More options provided by it are:
append("Hello There")
bold {
append("bold")
italic {
append("bold and italic")
underline {
append("then some text with underline")
}
}
}
At last, you can just to:
textView.text = string
