I see that you are looking for an implementation of the problem more than solving that error. Here you have a possible solution:
from itertools import chain
def involved(courses, person):
courses_info = chain.from_iterable(x.values() for x in courses.values())
return filter(lambda x: x['teacher'] == person, courses_info)
print involved(courses, 'Dave')
The first thing I do is getting the list of the courses and then filter by teacher's name.
You can use RVM(Ruby version manager) which helps in managing all versions of ruby on your machine , which is very helpful for you development (when migrating to unstable release to stable release )
or for Linux (ubuntu) go for
sudo apt-get install ruby1.8-dev
then sudo gem install rails
to verify it do rails -v
it will show version on rails
after that you can install bundles (required gems for development)
You can either add or replace fragment in your activity. Create a FrameLayout
in activity layout xml
file.
Then do this in your activity to add fragment:
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();
And to replace fragment do this:
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();
See Android documentation on adding a fragment to an activity or following related questions on SO:
Difference between add(), replace(), and addToBackStack()
Basic difference between add() and replace() method of Fragment
Difference between add() & replace() with Fragment's lifecycle
I have created a JSFiddle where I have two nested ng-repeats with tables, and the parent ng-repeat on tbody. If you inspect any row in the table, you will see there are six tbody elements, i.e. the parent level.

( Side note: This fills up the DOM if you have a lot of data on both levels, so I am therefore working on a directive to fetch data and replace, i.e. adding into DOM when clicking parent and removing when another is clicked or same parent again. To get the kind of behavior you find on Prisjakt.nu, if you scroll down to the computers listed and click on the row (not the links). If you do that and inspect elements you will see that a tr is added and then removed if parent is clicked again or another. )
btnSubmit_Click(btnSubmit,EventArgs.Empty);
You can combine selectors like this
$(".alert-box.warn, .alert-box.dead");
Or if you want a wildcard use the attribute-contains selector
$("[class*='alert-box']");
Note: Preferably you would know the element type or tag when using the selectors above. Knowing the tag can make the selector more efficient.
$("div.alert-box.warn, div.alert-box.dead");
$("div[class*='alert-box']");
Yes, there is better. Check the stat
or the fstat
function

you need to add it to Foo's prototype:
function Foo(){}
Foo.prototype.bar = function(){}
var x = new Foo()
x.bar()
Use msexcel-builder. Install it with:
npm install msexcel-builder
Then:
// Create a new workbook file in current working-path
var workbook = excelbuilder.createWorkbook('./', 'sample.xlsx')
// Create a new worksheet with 10 columns and 12 rows
var sheet1 = workbook.createSheet('sheet1', 10, 12);
// Fill some data
sheet1.set(1, 1, 'I am title');
for (var i = 2; i < 5; i++)
sheet1.set(i, 1, 'test'+i);
// Save it
workbook.save(function(ok){
if (!ok)
workbook.cancel();
else
console.log('congratulations, your workbook created');
});
You need to treat a table valued udf like a table, eg JOIN it
select Emp_Id
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items
Another way
@Html.TextAreaFor(model => model.Comments[0].Comment)
And in your css do this
textarea
{
font-family: inherit;
width: 650px;
height: 65px;
}
That DataType dealie allows carriage returns in the data, not everybody likes those.
I'm not sure what you're trying to achieve, but you may want to consider using jQuery, which allows you to put your code in the head tag or a separate script file and still have the code executed after the DOM has loaded.
You can then do something like:
$(document).ready(function() {
$(document).remove();
});
as well as selectively removing elements (all DIVs, only DIVs with certain classes, etc.)
If any one still reading this then, to access in cshtml file I used in following way.
<li>Hello @User.Identity.Name</li>
GNU linker, in my case companion of GCC 8.1.0, well detects not re-declared pure virtual methods, but above certain complexity of class design it fails to identify missing implementation of methods and answers with a flat "V-Table Missing",
or even tends to report missing implementation, in spite it is there.
The only solution then is to verify consistency of declaration of implementation manually, method by method.
You can throw your own custom errors by extending the Exception class.
class CustomException : Exception {
[string] $additionalData
CustomException($Message, $additionalData) : base($Message) {
$this.additionalData = $additionalData
}
}
try {
throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
# NOTE: To access your custom exception you must use $_.Exception
Write-Output $_.Exception.additionalData
# This will produce the error message: Didn't catch it the second time
throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}
You may like to try something like this which covers all the bases, including not relying on whitespace after the number:
>>> import re
>>> numeric_const_pattern = r"""
... [-+]? # optional sign
... (?:
... (?: \d* \. \d+ ) # .1 .12 .123 etc 9.1 etc 98.1 etc
... |
... (?: \d+ \.? ) # 1. 12. 123. etc 1 12 123 etc
... )
... # followed by optional exponent part if desired
... (?: [Ee] [+-]? \d+ ) ?
... """
>>> rx = re.compile(numeric_const_pattern, re.VERBOSE)
>>> rx.findall(".1 .12 9.1 98.1 1. 12. 1 12")
['.1', '.12', '9.1', '98.1', '1.', '12.', '1', '12']
>>> rx.findall("-1 +1 2e9 +2E+09 -2e-9")
['-1', '+1', '2e9', '+2E+09', '-2e-9']
>>> rx.findall("current level: -2.03e+99db")
['-2.03e+99']
>>>
For easy copy-pasting:
numeric_const_pattern = '[-+]? (?: (?: \d* \. \d+ ) | (?: \d+ \.? ) )(?: [Ee] [+-]? \d+ ) ?'
rx = re.compile(numeric_const_pattern, re.VERBOSE)
rx.findall("Some example: Jr. it. was .23 between 2.3 and 42.31 seconds")
When I used above code.It show me translated text as question mark like (???????).Then I convert from WebClient to HttpClient then I got a accurate result.So you can used code like this.
public static string TranslateText( string input, string languagePair)
{
string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
HttpClient httpClient = new HttpClient();
string result = httpClient.GetStringAsync(url).Result;
result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
result = result.Substring(result.IndexOf(">") + 1);
result = result.Substring(0, result.IndexOf("</span>"));
return result.Trim();
}
Then you Call a function like.You put first two letter of any language pair.
From English(en) To Urdu(ur).
TranslateText(line, "en|ur")
Type Conversions T() where T is the desired datatype of the result are quite simple in GoLang.
In my program, I scan an integer i from the user input, perform a type conversion on it and store it in the variable f. The output prints the float64
equivalent of the int
input. float32
datatype is also available in GoLang
Code:
package main
import "fmt"
func main() {
var i int
fmt.Println("Enter an Integer input: ")
fmt.Scanf("%d", &i)
f := float64(i)
fmt.Printf("The float64 representation of %d is %f\n", i, f)
}
Solution:
>>> Enter an Integer input:
>>> 232332
>>> The float64 representation of 232332 is 232332.000000
Pylint message control is documented in the Pylint manual:
Is it possible to locally disable a particular message?
Yes, this feature has been added in Pylint 0.11. This may be done by adding
# pylint: disable=some-message,another-one
at the desired block level or at the end of the desired line of code.
You can use the message code or the symbolic names.
For example,
def test():
# Disable all the no-member violations in this function
# pylint: disable=no-member
...
global VAR # pylint: disable=global-statement
The manual also has further examples.
There is a wiki that documents all Pylint messages and their codes.
When using IN
with a collection-valued parameter you don't need (...)
:
@NamedQuery(name = "EventLog.viewDatesInclude",
query = "SELECT el FROM EventLog el WHERE el.timeMark >= :dateFrom AND "
+ "el.timeMark <= :dateTo AND "
+ "el.name IN :inclList")
Found this solution using PdfRenderer.

Use the PasteSpecial method:
sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues
BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).
There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!
Example: To be placed in AssemblyInfo.cs
[assembly: InternalsVisibleTo("OtherAssembly")]
You can create a function with the pattern ShouldSerialize{PropertyName}
which tells the XmlSerializer if it should serialize the member or not.
For example, if your class property is called MyNullableInt
you could have
public bool ShouldSerializeMyNullableInt()
{
return MyNullableInt.HasValue;
}
Here is a full sample
public class Person
{
public string Name {get;set;}
public int? Age {get;set;}
public bool ShouldSerializeAge()
{
return Age.HasValue;
}
}
Serialized with the following code
Person thePerson = new Person(){Name="Chris"};
XmlSerializer xs = new XmlSerializer(typeof(Person));
StringWriter sw = new StringWriter();
xs.Serialize(sw, thePerson);
Results in the followng XML - Notice there is no Age
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Name>Chris</Name>
</Person>
Try this site full of Python Practice Problems. It leans towards problems that has already been solved so that you'll have reference solutions.
You're using the ajax function incorrectly. Since it's synchronous it'll return the data inline like so:
var remote = $.ajax({
type: "GET",
url: remote_url,
async: false
}).responseText;
There is also the Out-Null
cmdlet, which you can use in a pipeline, for example, Add-Item | Out-Null
.
NAME
Out-Null
SYNOPSIS
Deletes output instead of sending it to the console.
SYNTAX
Out-Null [-inputObject <psobject>] [<CommonParameters>]
DETAILED DESCRIPTION
The Out-Null cmdlet sends output to NULL, in effect, deleting it.
RELATED LINKS
Out-Printer
Out-Host
Out-File
Out-String
Out-Default
REMARKS
For more information, type: "get-help Out-Null -detailed".
For technical information, type: "get-help Out-Null -full".
In python: help(my_list.append)
for example, will give you the docstring of the function.
>>> my_list = []
>>> help(my_list.append)
Help on built-in function append:
append(...)
L.append(object) -- append object to end
SELECT DISTINCT OBJECT_NAME([id]),[text]
FROM syscomments
WHERE [id] IN (SELECT [id] FROM sysobjects WHERE xtype IN
('TF','FN','V','P') AND status >= 0) AND
([text] LIKE '%text to be search%' )
OBJECT_NAME([id]) --> Object Name (View,Store Procedure,Scalar Function,Table function name)
id (int) = Object identification number
xtype char(2) Object type. Can be one of the following object types:
FN = Scalar function
P = Stored procedure
V = View
TF = Table function
The pid files contains the process id (a number) of a given program. For example, Apache HTTPD may write its main process number to a pid file - which is a regular text file, nothing more than that - and later use the information there contained to stop itself. You can also use that information to kill the process yourself, using cat filename.pid | xargs kill
We have to set theme before calling 'super.onCreate()' and 'setContentView()' method.
Check out this link for applying new theme to whole application at runtime.
Check the URL it should be using https rather than http protocol.
In my case changing http to https in the URL solved it.
If you want to be able to call the func
with or without the parameter you can create a second func
of the same name which calls the other.
func test(firstThing: Int?) {
if firstThing != nil {
print(firstThing!)
}
print("done")
}
func test() {
test(firstThing: nil)
}
now you can call a function named test
without or without the parameter.
// both work
test()
test(firstThing: 5)
The most effective solution that I found is to define the parent element with display:flex
and align-items:center
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
.myclass{
display:flex;
align-items:center;
background-color:grey;
color:#fff;
height:50px;
}
</style>
</head>
<body>
<div class="myclass">
<input type="checkbox">
<label>do you love Ananas?
</label>
</div>
</body>
</html>
OUTPUT:
To send javascript obj to php using json and ajax:
js:
var dataPost = {
"var": "foo"
};
var dataString = JSON.stringify(dataPost);
$.ajax({
url: 'server.php',
data: {myData: dataString},
type: 'POST',
success: function(response) {
alert(response);
}
});
to use that object in php:
$obj = json_decode($_POST["myData"]);
echo $obj->var;
let layout = myCollectionView.collectionViewLayout as? UICollectionViewFlowLayout
layout?.minimumLineSpacing = 8
Actually openssl
command is a better tool than curl
for checking and debugging SSL. Here is an example with openssl
:
openssl s_client -showcerts -connect stackoverflow.com:443 < /dev/null
and < /dev/null
is for adding EOL to the STDIN
otherwise it hangs on the Terminal.
But if you liked, you can wrap some useful openssl
commands with curl
(as I did with curly) and make it more human readable like so:
# check if SSL is valid
>>> curly --ssl valid -d stackoverflow.com
Verify return code: 0 (ok)
issuer=C = US
O = Let's Encrypt
CN = R3
subject=CN = *.stackexchange.com
option: ssl
action: valid
status: OK
# check how many days it will be valid
>>> curly --ssl date -d stackoverflow.com
Verify return code: 0 (ok)
from: Tue Feb 9 16:13:16 UTC 2021
till: Mon May 10 16:13:16 UTC 2021
days total: 89
days passed: 8
days left: 81
option: ssl
action: date
status: OK
# check which names it supports

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!
I see you are connecting to a remote host. Now the question is what type of a network are you using to connect to the internet?
WINDOWS
If it's a mobile broadband device then get your machines IP address and add it to your hosting server so that your host server can allow connections coming from your machine.[your host might have turned this off due to security reasons]. Note that every time you use a different network device your IP changes.
If you are using a LAN then set a static IP address on your machine then add it to your host.
I hope this helps!! :)

I solved this error by closing the project, removing it from eclipse and then importing it again.
Might be a little simpler than to redo the whole workspace setup.
As ping
works, but telnet
to port 80
does not, the HTTP port 80
is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?).
You need to add some code to your python program, that handles the proxy, like described here:
PHP's getimagesize()
returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:
var $imagedata = getimagesize("someimage.jpg");
print "Image width is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];
For further information, see the documentation.
How about netstat?

First confusion on my side was about where exactly to set SSH Keys in BitBucket.
I am new to BitBucket and I was setting a Deployment Key which gives read-access only.
So make sure you are setting your rsa pub key
in your BitBucket Account Settings.
Click your BitBucket avatar and select Bitbucket Settings(Manage account). There you'll be able to set SSH Keys.
I simply deleted the Deployment Key, I don't need any for now. And it worked

I had similar issue with the index.html being cached by the browser or more tricky by middle cdn/proxies (F5 will not help you).
I looked for a solution which verifies 100% that the client has the latest index.html version, luckily I found this solution by Henrik Peinar:
https://blog.nodeswat.com/automagic-reload-for-clients-after-deploy-with-angular-4-8440c9fdd96c
The solution solve also the case where the client stays with the browser open for days, the client checks for updates on intervals and reload if newer version deployd.
The solution is a bit tricky but works like a charm:
ng cli -- prod
produces hashed files with one of them called main.[hash].jsSince Henrik Peinar solution was for angular 4, there were minor changes, I place also the fixed scripts here:
VersionCheckService :
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable()
export class VersionCheckService {
// this will be replaced by actual hash post-build.js
private currentHash = '{{POST_BUILD_ENTERS_HASH_HERE}}';
constructor(private http: HttpClient) {}
/**
* Checks in every set frequency the version of frontend application
* @param url
* @param {number} frequency - in milliseconds, defaults to 30 minutes
*/
public initVersionCheck(url, frequency = 1000 * 60 * 30) {
//check for first time
this.checkVersion(url);
setInterval(() => {
this.checkVersion(url);
}, frequency);
}
/**
* Will do the call and check if the hash has changed or not
* @param url
*/
private checkVersion(url) {
// timestamp these requests to invalidate caches
this.http.get(url + '?t=' + new Date().getTime())
.subscribe(
(response: any) => {
const hash = response.hash;
const hashChanged = this.hasHashChanged(this.currentHash, hash);
// If new version, do something
if (hashChanged) {
// ENTER YOUR CODE TO DO SOMETHING UPON VERSION CHANGE
// for an example: location.reload();
// or to ensure cdn miss: window.location.replace(window.location.href + '?rand=' + Math.random());
}
// store the new hash so we wouldn't trigger versionChange again
// only necessary in case you did not force refresh
this.currentHash = hash;
},
(err) => {
console.error(err, 'Could not get version');
}
);
}
/**
* Checks if hash has changed.
* This file has the JS hash, if it is a different one than in the version.json
* we are dealing with version change
* @param currentHash
* @param newHash
* @returns {boolean}
*/
private hasHashChanged(currentHash, newHash) {
if (!currentHash || currentHash === '{{POST_BUILD_ENTERS_HASH_HERE}}') {
return false;
}
return currentHash !== newHash;
}
}
change to main AppComponent:
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
constructor(private versionCheckService: VersionCheckService) {
}
ngOnInit() {
console.log('AppComponent.ngOnInit() environment.versionCheckUrl=' + environment.versionCheckUrl);
if (environment.versionCheckUrl) {
this.versionCheckService.initVersionCheck(environment.versionCheckUrl);
}
}
}
The post-build script that makes the magic, post-build.js:
const path = require('path');
const fs = require('fs');
const util = require('util');
// get application version from package.json
const appVersion = require('../package.json').version;
// promisify core API's
const readDir = util.promisify(fs.readdir);
const writeFile = util.promisify(fs.writeFile);
const readFile = util.promisify(fs.readFile);
console.log('\nRunning post-build tasks');
// our version.json will be in the dist folder
const versionFilePath = path.join(__dirname + '/../dist/version.json');
let mainHash = '';
let mainBundleFile = '';
// RegExp to find main.bundle.js, even if it doesn't include a hash in it's name (dev build)
let mainBundleRegexp = /^main.?([a-z0-9]*)?.js$/;
// read the dist folder files and find the one we're looking for
readDir(path.join(__dirname, '../dist/'))
.then(files => {
mainBundleFile = files.find(f => mainBundleRegexp.test(f));
if (mainBundleFile) {
let matchHash = mainBundleFile.match(mainBundleRegexp);
// if it has a hash in it's name, mark it down
if (matchHash.length > 1 && !!matchHash[1]) {
mainHash = matchHash[1];
}
}
console.log(`Writing version and hash to ${versionFilePath}`);
// write current version and hash into the version.json file
const src = `{"version": "${appVersion}", "hash": "${mainHash}"}`;
return writeFile(versionFilePath, src);
}).then(() => {
// main bundle file not found, dev build?
if (!mainBundleFile) {
return;
}
console.log(`Replacing hash in the ${mainBundleFile}`);
// replace hash placeholder in our main.js file so the code knows it's current hash
const mainFilepath = path.join(__dirname, '../dist/', mainBundleFile);
return readFile(mainFilepath, 'utf8')
.then(mainFileData => {
const replacedFile = mainFileData.replace('{{POST_BUILD_ENTERS_HASH_HERE}}', mainHash);
return writeFile(mainFilepath, replacedFile);
});
}).catch(err => {
console.log('Error with post build:', err);
});
simply place the script in (new) build folder run the script using node ./build/post-build.js
after building dist folder using ng build --prod
If any one want it in Java, Here is my Answer, For this you have to call Another Thread.
After some testing with an icon with 8, 16, 20, 24, 32, 40, 48, 64, 96, 128 and 256 pixels (256 in PNG) in Windows 7:
So 8, 32 were never used (it's strange to me for 32) and 128 only by Windows Photo Viewer with a very high dpi screen, i.e. almot never used.
It means your icon should at least provide 16, 48 and 256 for Windows 7. For supporting newer screens with high resolutions, you should provide 16, 20, 24, 40, 48, 64, 96, and 256. For Windows 7, all pictures can be compressed using PNG but for backward compatibility with Windows XP, 16 to 48 should not be compressed.
You can just pass it
def my_function(my_data):
my_data["schoolname"] = "something"
print my_data
or if you really want to
def my_function(**kwargs):
kwargs["schoolname"] = "something"
print kwargs
In my case junk files from editor caused the problem. I had a config as below:
#...
http {
# ...
include ../sites/*;
}
In the ../sites
directory initially I had a default.config
file.
However, by mistake I saved duplicate files as default.config.save
and default.config.save.1
.
Removing them resolved the issue.
You shouldn't confuse arrays with lists.
This is a list: {...}
. It has no length or other Array properties.
This is an array: [...]
. You can use array functions, methods and so, like someone suggested here: someArray.toString()
;
someObj.toString();
will not work on any other object types, like lists.
Sorry for late reply.But this would work properly.

Calender c=Calender.getInstance();

True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.
In Sourcetree UI (https://www.sourcetreeapp.com/), you can find history of a file by selecting 'Log Selected' option in right click context menu:
It would show the history of all the commits.
This is the top hit on Google for "nginx redirect". If you got here just wanting to redirect a single location:
location = /content/unique-page-name {
return 301 /new-name/unique-page-name;
}
It´s a issue of rounding the result, the solution for me is the following.
divider.divide(dividend,RoundingMode.HALF_UP);
Actually, it's because CSS defines 100% relative to the entire width of the container, including its margins, borders, and padding; that means that the space avail. to its contents is some amount smaller than 100%, unless the container has no margins, borders, or padding.
This is counter-intuitive and widely regarded by many to be a mistake that we are now stuck with. It effectively means that % dimensions are no good for anything other than a top level container, and even then, only if it has no margins, borders or padding.
Note that the text field's margins, borders, and padding are included in the CSS size specified for it - it's the container's which throw things off.
I have tolerably worked around it by using 98%, but that is a less than perfect solution, since the input fields tend to fall further short as the container gets larger.
EDIT: I came across this similar question - I've never tried the answer given, and I don't know for sure if it applies to your problem, but it seems like it will.
//To clear When Clear Button is Clicked
firstName = (EditText) findViewById(R.id.firstName);

This will help to clear the wrong keywords that you have typed in so instead of pressing backspace again and again you can simply click the button to clear everything.It Worked For me. Hope It Helps
You'll need to use a different SimpleDateFormat
object for each different pattern. That said, you don't need that many different ones, thanks to this:
Number: For formatting, the number of pattern letters is the minimum number of digits, and shorter numbers are zero-padded to this amount. For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.
So, you'll need these formats:
"M/y"
(that covers 9/09
, 9/2009
, and 09/2009
)"M/d/y"
(that covers 9/1/2009
)"M-d-y"
(that covers 9-1-2009
)So, my advice would be to write a method that works something like this (untested):
// ...
List<String> formatStrings = Arrays.asList("M/y", "M/d/y", "M-d-y");
// ...
Date tryParse(String dateString)
{
for (String formatString : formatStrings)
{
try
{
return new SimpleDateFormat(formatString).parse(dateString);
}
catch (ParseException e) {}
}
return null;
}
There is also -l:libstatic1.a
(minus l colon) variant of -l option in gcc which can be used to link static library (Thanks to https://stackoverflow.com/a/20728782). Is it documented? Not in the official documentation of gcc (which is not exact for shared libs too): https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html
-llibrary -l library
Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.) ... The only difference between using an -l option and specifying a file name is that -l surrounds library with ‘lib’ and ‘.a’ and searches several directories.
The binutils ld doc describes it. The -lname
option will do search for libname.so
then for libname.a
adding lib prefix and .so
(if enabled at the moment) or .a
suffix. But -l:name
option will only search exactly for the name specified:
https://sourceware.org/binutils/docs/ld/Options.html
-l namespec --library=namespec
Add the archive or object file specified by
namespec
to the list of files to link. This option may be used any number of times. Ifnamespec
is of the form:filename
, ld will search the library path for a file calledfilename
, otherwise it will search the library path for a file calledlibnamespec.a
.On systems which support shared libraries, ld may also search for files other than
libnamespec.a
. Specifically, on ELF and SunOS systems, ld will search a directory for a library calledlibnamespec.so
before searching for one calledlibnamespec.a
. (By convention, a.so
extension indicates a shared library.) Note that this behavior does not apply to:filename
, which always specifies a file calledfilename
.The linker will search an archive only once, at the location where it is specified on the command line. If the archive defines a symbol which was undefined in some object which appeared before the archive on the command line, the linker will include the appropriate file(s) from the archive. However, an undefined symbol in an object appearing later on the command line will not cause the linker to search the archive again.
See the
-(
option for a way to force the linker to search archives multiple times.You may list the same archive multiple times on the command line.
This type of archive searching is standard for Unix linkers. However, if you are using ld on AIX, note that it is different from the behaviour of the AIX linker.
The variant -l:namespec
is documented since 2.18 version of binutils (2007): https://sourceware.org/binutils/docs-2.18/ld/Options.html
Range("A1").value = Environ("Username")
This is better than Application.Username
, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.
Application Username
is the name of the User set in Excel > Tools > Options Environ("Username")
is the name you registered for Windows; see Control Panel >SystemYou can do this with position:absolute;
on the #second
div like this :
CSS :
#wrapper{
position:relative;
}
#second {
position:absolute;
top:200px;
bottom:0;
left:0;
width:300px;
background-color:#9ACD32;
}
EDIT : Alternative solution
Depending on your layout and the content you have in those divs, you could make it much more simple and with less markup like this :
HTML :
<div id="wrapper">
<div id="first"></div>
</div>
CSS :
#wrapper {
height:100%;
width:300px;
background-color:#9ACD32;
}
#first {
background-color:#F5DEB3;
height: 200px;
}
If you do not have a variable declared as array you can create a check:
if(x && x.constructor==Array && x.length){
console.log("is array and filed");
}else{
var x= [];
console.log('x = empty array');
}
This checks if variable x exists and if it is, checks if it is a filled array. else it creates an empty array (or you can do other stuff);
If you are certain there is an array variable created there is a simple check:
var x = [];
if(!x.length){
console.log('empty');
} else {
console.log('full');
}
You can check my fiddle here with shows most possible ways to check array.
In my experience storing all the settings in a database table is the best solution. Don't even worry about performance. Today's databases are fast and can easily store thousands columns in a table. I learned this the hard way - before I was serilizing/deserializing - nightmare. Storing it in local file or registry has one big problem - if you have to support your app and computer is off - user is not in front of it - there is nothing you can do.... if setings are in DB - you can changed them and viola not to mention that you can compare the settings....
In case it helps anyone I had the same error. It turns out my page had not been scrapped by Facebook in awhile and it was an old error. There was a scrape again button on the page that fixed it.
The easiest way to get a new list would be:
List<long> unique = longs.Distinct().ToList();
Is that good enough for you, or do you need to mutate the existing list? The latter is significantly more long-winded.
Note that Distinct()
isn't guaranteed to preserve the original order, but in the current implementation it will - and that's the most natural implementation. See my Edulinq blog post about Distinct()
for more information.
If you don't need it to be a List<long>
, you could just keep it as:
IEnumerable<long> unique = longs.Distinct();
At this point it will go through the de-duping each time you iterate over unique
though. Whether that's good or not will depend on your requirements.
I use the same method suggested by chalup,
ParentDirectory = <your directory>
RCC_DIR = "$$ParentDirectory\Build\RCCFiles"
UI_DIR = "$$ParentDirectory\Build\UICFiles"
MOC_DIR = "$$ParentDirectory\Build\MOCFiles"
OBJECTS_DIR = "$$ParentDirectory\Build\ObjFiles"
CONFIG(debug, debug|release) {
DESTDIR = "$$ParentDirectory\debug"
}
CONFIG(release, debug|release) {
DESTDIR = "$$ParentDirectory\release"
}
Angular's own ng-Router takes URLs
into consideration while routing, UI-Router takes states
in addition to URLs.
States are bound to named, nested and parallel views, allowing you to powerfully manage your application's interface.
While in ng-router, you have to be very careful about URLs when providing links via <a href="">
tag, in UI-Router you have to only keep state
in mind. You provide links like <a ui-sref="">
. Note that even if you use <a href="">
in UI-Router, just like you would do in ng-router, it will still work.
So, even if you decide to change your URL some day, your state
will remain same and you need to change URL only at .config
.
While ngRouter can be used to make simple apps, UI-Router makes development much easier for complex apps. Here its wiki.
// This is for first date
first = new Date(2010, 03, 08, 15, 30, 10); // Get the first date epoch object
document.write((first.getTime())/1000); // get the actual epoch values
second = new Date(2012, 03, 08, 15, 30, 10); // Get the first date epoch object
document.write((second.getTime())/1000); // get the actual epoch values
diff= second - first ;
one_day_epoch = 24*60*60 ; // calculating one epoch
if ( diff/ one_day_epoch > 365 ) // check , is it exceei
{
alert( 'date is exceeding one year');
}
Although a bit unstandard, a possible solution is to contain the content you want to show/hide inside the <a>
so it can be reachable through CSS:
a .hidden {_x000D_
visibility: hidden;_x000D_
}_x000D_
_x000D_
a:visited .hidden {_x000D_
visibility: visible;_x000D_
}
_x000D_
<div id="container">_x000D_
<a href="#">_x000D_
A_x000D_
<div class="hidden">hidden content</div>_x000D_
</a>_x000D_
</div>
_x000D_
My first thought was to try passing it '30/03/09 16:31:32.123' (with a period instead of a colon between the seconds and the milliseconds.) But that didn't work. A quick glance at the docs indicates that fractional seconds are ignored in any case...
Ah, version differences. This was reported as a bug and now in 2.6+ you can use "%S.%f" to parse it.
Calling setOpaque(false)
on the upper JPanel
should work.
From your comment, it sounds like Swing painting may be broken somewhere -
First - you probably wanted to override paintComponent()
rather than paint()
in whatever component you have paint()
overridden in.
Second - when you do override paintComponent()
, you'll first want to call super.paintComponent()
first to do all the default Swing painting stuff (of which honoring setOpaque()
is one).
Example -
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TwoPanels {
public static void main(String[] args) {
JPanel p = new JPanel();
// setting layout to null so we can make panels overlap
p.setLayout(null);
CirclePanel topPanel = new CirclePanel();
// drawing should be in blue
topPanel.setForeground(Color.blue);
// background should be black, except it's not opaque, so
// background will not be drawn
topPanel.setBackground(Color.black);
// set opaque to false - background not drawn
topPanel.setOpaque(false);
topPanel.setBounds(50, 50, 100, 100);
// add topPanel - components paint in order added,
// so add topPanel first
p.add(topPanel);
CirclePanel bottomPanel = new CirclePanel();
// drawing in green
bottomPanel.setForeground(Color.green);
// background in cyan
bottomPanel.setBackground(Color.cyan);
// and it will show this time, because opaque is true
bottomPanel.setOpaque(true);
bottomPanel.setBounds(30, 30, 100, 100);
// add bottomPanel last...
p.add(bottomPanel);
// frame handling code...
JFrame f = new JFrame("Two Panels");
f.setContentPane(p);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(300, 300);
f.setLocationRelativeTo(null);
f.setVisible(true);
}
// Panel with a circle drawn on it.
private static class CirclePanel extends JPanel {
// This is Swing, so override paint*Component* - not paint
protected void paintComponent(Graphics g) {
// call super.paintComponent to get default Swing
// painting behavior (opaque honored, etc.)
super.paintComponent(g);
int x = 10;
int y = 10;
int width = getWidth() - 20;
int height = getHeight() - 20;
g.drawArc(x, y, width, height, 0, 360);
}
}
}
Better late than never... =)
You may take the concept of extended BaseRequestOptions
(from here https://angular.io/docs/ts/latest/guide/server-communication.html#!#override-default-request-options) and refresh the headers "on the fly" (not only in constructor). You may use getter/setter "headers" property override like this:
import { Injectable } from '@angular/core';
import { BaseRequestOptions, RequestOptions, Headers } from '@angular/http';
@Injectable()
export class DefaultRequestOptions extends BaseRequestOptions {
private superHeaders: Headers;
get headers() {
// Set the default 'Content-Type' header
this.superHeaders.set('Content-Type', 'application/json');
const token = localStorage.getItem('authToken');
if(token) {
this.superHeaders.set('Authorization', `Bearer ${token}`);
} else {
this.superHeaders.delete('Authorization');
}
return this.superHeaders;
}
set headers(headers: Headers) {
this.superHeaders = headers;
}
constructor() {
super();
}
}
export const requestOptionsProvider = { provide: RequestOptions, useClass: DefaultRequestOptions };
I used @jensgram solution to hide a div that contains a disabled input. So I hide the entire parent of the input.
Here is the code :
div:has(>input[disabled=disabled]) {
display: none;
}
Maybe it could help some of you.
Since your application is small, there is essentially no appreciable cost increase to using nvarchar over varchar, and you save yourself potential headaches down the road if you have a need to store unicode data.
UTF-8 is going to be the most space efficient unless a majority of the characters are from the CJK (Chinese, Japanese, and Korean) character space.
UTF-32 is best for random access by character offset into a byte-array.
I would assume you tried it without adding !important
?
Inline CSS (which is how JavaScript adds styling) overrides the stylesheet CSS. I'm pretty sure that's the case even when the stylesheet CSS rule has !important
.
Another question (maybe a stupid question but must be asked.): Is the element you are trying to work on display:block;
or display:inline-block;
?
Not knowing your expertise in CSS... inline elements don't always behave as you would expect.
I found myself in a similar predicament today while trying to run a command through a Node.js module:
I was using the PowerShell and trying to run:
command -e 'func($a)'
But with the extra symbols, PowerShell was mangling the arguments. To fix, I back-tick escaped double-quote marks:
command -e `"func($a)`"

Also beware of the UML version : it's been a long time now that << uses >> and << includes >> have been replaced by << include >>, and << extends >> by << extend >> AND generalization.
For me that's often the misleading point : as an example the Stephanie's post and link is about an old version :
When paying for an item, you may choose to pay on delivery, pay using paypal or pay by card. These are all alternatives to the "pay for item" use case. I may choose any of these options depending on my preference.
In fact there is no really alternative to "pay for item" ! In nowadays UML, "pay on delivery" is an extend, and "pay using paypal"/"pay by card" are specializations.
If you have andorid 9 in your mobile you must update Android SDK in Android Studio.
The isinstance
built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:
def my_print(text, begin, end):
"Print 'text' in UPPER between 'begin' and 'end' in lower"
try:
print begin.lower() + text.upper() + end.lower()
except (AttributeError, TypeError):
raise AssertionError('Input variables should be strings')
This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)
I suppose that you needed that in form of a script, but if someone else just want to have a look through the Jenkins GUI, that list can be found by selecting the "Environment Variables" section in contextual left menu of every build Select project => Select build => Environment Variables
button2.Enabled == true ;
must be button2.Enabled = true ;
.
You have a compare ==
where you should have an assign =

My mongo (3.2.9) was installed on Ubuntu, and my log file had the following lines:
2016-09-28T11:32:07.821+0100 E STORAGE [initandlisten] WiredTiger (13) [1475058727:821829][6785:0x7fa9684ecc80], file:WiredTiger.wt, connection: /var/lib/mongodb/WiredTiger.turtle: handle-open: open: Permission denied

So the problem was in permissions on /var/lib/mongodb folder.
sudo chown -R mongodb:mongodb /var/lib/mongodb/
sudo chmod -R 755 /var/lib/mongodb
Fixed it, although I do realise that may be not too secure (it's my own dev box I'm in my case), bit following the change both db and authentication worked.
You can actually just use
$("#form").attr("target", "NewAction");
As far as I know, this will NOT fail silently.
If the page is opening in a new target, you may need to make sure the URL is unique each time because Webkit (chrome/safari) will cache the fact you have visited that URL and won't perform the post.
For example
$("form").attr("action", "/Pages/GeneratePreview?" + new Date().getMilliseconds());
Here is good solution in JavaScript (with all required mathematics and live illustration) https://bl.ocks.org/milkbread/11000965
Though is_on
function in that solution needs modifications:
function is_on(a, b, c) {_x000D_
return Math.abs(distance(a,c) + distance(c,b) - distance(a,b))<0.000001;_x000D_
}
_x000D_
You can also get this error if you fail to include .htaccess or have a problem in it. The file should be something like this
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
You can also use .replaceWith()
, like this:
$("b").replaceWith(function() { return $(this).contents(); });
Or if you know it's just a string:
$("b").replaceWith(function() { return this.innerHTML; });
This can make a big difference if you're unwrapping a lot of elements since either approach above is significantly faster than the cost of .unwrap()
.
You can declare it yourself quite easily:
interface StringConstructor {
format: (formatString: string, ...replacement: any[]) => string;
}
String.format('','');
This is assuming that String.format is defined elsewhere. e.g. in Microsoft Ajax Toolkit : http://www.asp.net/ajaxlibrary/Reference.String-format-Function.ashx
By default, the DirectoryIndex is set to:
DirectoryIndex index.html index.htm default.htm index.php index.php3 index.phtml index.php5 index.shtml mwindex.phtml
Apache will look for each of the above files, in order, and serve the first one it finds when a visitor requests just a directory. If the webserver finds no files in the current directory that match names in the DirectoryIndex directive, then a directory listing will be displayed to the browser, showing all files in the current directory.
The order should be DirectoryIndex index.html index.php
// default is index.html

While pidof
and pgrep
are great tools for determining what's running, they are both, unfortunately, unavailable on some operating systems. A definite fail safe would be to use the following: ps cax | grep command
The output on Gentoo Linux:
14484 ? S 0:00 apache2 14667 ? S 0:00 apache2 19620 ? Sl 0:00 apache2 21132 ? Ss 0:04 apache2
The output on OS X:
42582 ?? Z 0:00.00 (smbclient) 46529 ?? Z 0:00.00 (smbclient) 46539 ?? Z 0:00.00 (smbclient) 46547 ?? Z 0:00.00 (smbclient) 46586 ?? Z 0:00.00 (smbclient) 46594 ?? Z 0:00.00 (smbclient)
On both Linux and OS X, grep returns an exit code so it's easy to check if the process was found or not:
#!/bin/bash
ps cax | grep httpd > /dev/null
if [ $? -eq 0 ]; then
echo "Process is running."
else
echo "Process is not running."
fi
Furthermore, if you would like the list of PIDs, you could easily grep for those as well:
ps cax | grep httpd | grep -o '^[ ]*[0-9]*'
Whose output is the same on Linux and OS X:
3519 3521 3523 3524
The output of the following is an empty string, making this approach safe for processes that are not running:
echo ps cax | grep aasdfasdf | grep -o '^[ ]*[0-9]*'
This approach is suitable for writing a simple empty string test, then even iterating through the discovered PIDs.
#!/bin/bash
PROCESS=$1
PIDS=`ps cax | grep $PROCESS | grep -o '^[ ]*[0-9]*'`
if [ -z "$PIDS" ]; then
echo "Process not running." 1>&2
exit 1
else
for PID in $PIDS; do
echo $PID
done
fi
You can test it by saving it to a file (named "running") with execute permissions (chmod +x running) and executing it with a parameter: ./running "httpd"
#!/bin/bash
ps cax | grep httpd
if [ $? -eq 0 ]; then
echo "Process is running."
else
echo "Process is not running."
fi
WARNING!!!
Please keep in mind that you're simply parsing the output of ps ax
which means that, as seen in the Linux output, it is not simply matching on processes, but also the arguments passed to that program. I highly recommend being as specific as possible when using this method (e.g. ./running "mysql"
will also match 'mysqld' processes). I highly recommend using which
to check against a full path where possible.
References:
Well, you can just put multiple "where" clauses in directly, but I don't think you want to. Multiple "where" clauses ends up with a more restrictive filter - I think you want a less restrictive one. I think you really want:
DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
where r.Field<string>("UserName") != "XXXX" &&
r.Field<string>("UserName") != "YYYY"
select r;
DataTable newDT = query.CopyToDataTable();
Note the && instead of ||. You want to select the row if the username isn't XXXX and the username isn't YYYY.
EDIT: If you have a whole collection, it's even easier. Suppose the collection is called ignoredUserNames
:
DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
where !ignoredUserNames.Contains(r.Field<string>("UserName"))
select r;
DataTable newDT = query.CopyToDataTable();
Ideally you'd want to make this a HashSet<string>
to avoid the Contains
call taking a long time, but if the collection is small enough it won't make much odds.
When I create a table using SSMS 2008, I see 3 panes:
In the table properties pane, there is a field: Schema
which allows you to select the schema.
As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.
So:
Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default
Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com
You may need to wait 5-10 mins for the DNS records to update but that's all you need.
public static double toMilliSeconds(double day)

return (long) (day * 24 * 60 * 60 * 1000);
}
The reason you're receiving that error is that you're using the runtime build which doesn't support templates in HTML files as seen here vuejs.org
In essence what happens with vue loaded files is that their templates are compile time converted into render functions where as your base function was trying to compile from your html element.
Solutions that use SUBSTRING
and concatenation +
are nearly independent of RDBMS. Here is a short solution that is specific to SQL Server:
declare @x int = 123456789
select stuff(stuff(@x, 4, 0, '-'), 8, 0, '-')
you can do using just one line of code
>>> import re
>>> re.findall(r'\d{1,5}','gfgfdAAA1234ZZZuijjk')
>>> ['1234']
result will receive list...
AlexRobbins' answer worked for me, except that the first two lines need to be in the model (perhaps this was assumed?), and should reference self:
def book_author(self):
return self.book.author
Then the admin part works nicely.
Finish closes the whole application, this is is something i hate in Android development not finish that is fine but that they do not keep up wit ok syntax they have
startActivity(intent)
Why not
closeActivity(intent) ?
Python or Python3 with MySQL, you will need these. These libraries use MySQL's connector for C and Python (you need the C libraries installed as well), which overcome some of the limitations of the mysqldb libraries.
sudo apt-get install libmysqlclient-dev
sudo apt-get install python-mysql.connector
sudo apt-get install python3-mysql.connector
You can run:
valgrind --leak-check=full --log-file="logfile.out" -v [your_program(and its arguments)]
ActiveRecord stores validation errors in an array called errors
. If you have a User
model then you would access the validation errors in a given instance like so:
@user = User.create[params[:user]] # create will automatically call validators
if @user.errors.any? # If there are errors, do something
# You can iterate through all messages by attribute type and validation message
# This will be something like:
# attribute = 'name'
# message = 'cannot be left blank'
@user.errors.each do |attribute, message|
# do stuff for each error
end
# Or if you prefer, you can get the full message in single string, like so:
# message = 'Name cannot be left blank'
@users.errors.full_messages.each do |message|
# do stuff for each error
end
# To get all errors associated with a single attribute, do the following:
if @user.errors.include?(:name)
name_errors = @user.errors[:name]
if name_errors.kind_of?(Array)
name_errors.each do |error|
# do stuff for each error on the name attribute
end
else
error = name_errors
# do stuff for the one error on the name attribute.
end
end
end
Of course you can also do any of this in the views instead of the controller, should you want to just display the first error to the user or something.
Assign the values of nested json
to struct until you know the underlying type of json keys:-
package main
import (
"encoding/json"
"fmt"
)
// Object
type Object struct {
Foo map[string]map[string]string `json:"foo"`
More string `json:"more"`
}
func main(){
someJSONString := []byte(`{"foo":{ "bar": "1", "baz": "2" }, "more": "text"}`)
var obj Object
err := json.Unmarshal(someJSONString, &obj)
if err != nil{
fmt.Println(err)
}
fmt.Println("jsonObj", obj)
}
You can get the total number of rows containing a specific name using:
SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'
Given the count, you can now get the nth row using:
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1
Where 1 <= n <= COUNT(*) from the first query.
Example:
getting the 3rd row
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1
There's also WordNet. Its data files format are well-documented.
I used it for building an embeddable dictionary library for iOS developers (www.lexicontext.com) and also in one of my apps.
Code that is built into shared libraries should normally be position-independent code, so that the shared library can readily be loaded at (more or less) any address in memory. The -fPIC
option ensures that GCC produces such code.
Here is a Bash one-liner that is based on simply converting each line to a column and paste
-ing them together:
echo '' > tmp1; \
cat m.txt | while read l ; \
do paste tmp1 <(echo $l | tr -s ' ' \\n) > tmp2; \
cp tmp2 tmp1; \
done; \
cat tmp1
m.txt:
0 1 2
4 5 6
7 8 9
10 11 12
creates tmp1
file so it's not empty.
reads each line and transforms it into a column using tr
pastes the new column to the tmp1
file
copies result back into tmp1
.
PS: I really wanted to use io-descriptors but couldn't get them to work.

In my case, in iOS 13, I only had to implement the whole function and selector calling parts put in to main thread.
Inline tag is used to add another src of document to the current html element.
In your case an video of a youtube and we need to specify the html type(4 or 5) to the browser externally to the link
so add ?html=5 to the end of the link.. :)
I like this example, which for now, leaves out the check which you could add inside the while block:
ifstream iFile("input.txt"); // input.txt has integers, one per line
int x;
while (iFile >> x)
{
cerr << x << endl;
}
Not sure how safe it is...
Using back ticks you can have multiline strings:
package main
import "fmt"
func main() {
message := `This is a
Multi-line Text String
Because it uses the raw-string back ticks
instead of quotes.
`
fmt.Printf("%s", message)
}
Instead of using either the double quote (“) or single quote symbols (‘), instead use back-ticks to define the start and end of the string. You can then wrap it across lines.
If you indent the string though, remember that the white space will count.
Please check the playground and do experiments with it.
You need to use \" for escaping " character (\ escape the following character
sed -i 's/\"http://www.fubar.com\"/URL_FUBAR/g'
I might suggest this, as a more gracefully degrading solution, using preventDefault
:
$('a').click(function(e) {
e.preventDefault(); //stop the browser from following
window.location.href = 'uploads/file.doc';
});
<a href="no-script.html">Download now!</a>
Even if there's no Javascript, at least this way the user will get some feedback.
I solved the same problem for my own program by installing python3-pyqt4
.
I'm not using Python 3 but it still helped.
In some OS you need to use new libraries: libmagick++4 libmagick++-dev
You can use:
sudo apt-get install libmagick++4 libmagick++-dev
function remote_file_exists($url){
return(bool)preg_match('~HTTP/1\.\d\s+200\s+OK~', @current(get_headers($url)));
}
$ff = "http://www.emeditor.com/pub/emed32_11.0.5.exe";
if(remote_file_exists($ff)){
echo "file exist!";
}
else{
echo "file not exist!!!";
}
Open project in android studio click file and click Invalidate Caches/Restart
I've used a DOS command line to do this. Two lines, actually. The first one to make the "current directory" the folder where the file is - or the root folder of a group of folders where the file can be. The second line does the search.
CD C:\TheFolder
C:\TheFolder>FINDSTR /L /S /I /N /C:"TheString" *.PRG
You can find details about the parameters at this link.
Hope it helps!
I'm pretty sure all of the examples above only reload the iframe with its original src, not its current URL.
$('#frameId').attr('src', function () { return $(this).contents().get(0).location.href });
That should reload using the current url.
Here is my working solution (SCSS):
.item{
display: flex;
justify-content: space-between;
align-items: center;
min-height: 120px;
&:after{
content:'';
min-height:inherit;
font-size:0;
}
}
If your input string doesn't contain forward slashes then you can use basename
and a subshell:
$ basename "$(echo 'maps.google.com' | tr '.' '/')"
This doesn't use sed
or awk
but it also doesn't use cut
either, so I'm not quite sure if it qualifies as an answer to the question as its worded.
This doesn't work well if processing input strings that can contain forward slashes. A workaround for that situation would be to replace forward slash with some other character that you know isn't part of a valid input string. For example, the pipe (|
) character is also not allowed in filenames, so this would work:
$ basename "$(echo 'maps.google.com/some/url/things' | tr '/' '|' | tr '.' '/')" | tr '|' '/'
The problem here is that you are including commands.c
in commands.h
before the function prototype. Therefore, the C pre-processor inserts the content of commands.c
into commands.h
before the function prototype. commands.c
contains the function definition. As a result, the function definition ends up before than the function declaration causing the error.
The content of commands.h
after the pre-processor phase looks like this:
#ifndef COMMANDS_H_
#define COMMANDS_H_
// function definition
void f123(){
}
// function declaration
void f123();
#endif /* COMMANDS_H_ */
This is an error because you can't declare a function after its definition in C. If you swapped #include "commands.c"
and the function declaration the error shouldn't happen because, now, the function prototype comes before the function declaration.
However, including a .c
file is a bad practice and should be avoided. A better solution for this problem would be to include commands.h
in commands.c
and link the compiled version of command to the main file. For example:
commands.h
#ifndef COMMANDS_H_
#define COMMANDS_H_
void f123(); // function declaration
#endif
commands.c
#include "commands.h"
void f123(){} // function definition
I think you could do something like this:
var $child = $("#parentId").append("<div></div>").children("div:last-child");
The parent #parentId is returned from the append, so add a jquery children query to it to get the last div child inserted.
$child is then the jquery wrapped child div that was added.
The original code is a bit cumbersome and you might want to use the collections.deque instead if you want to use BFS to find if a path exists between 2 points on the graph. Here is a quick solution I hacked up:
Note: this method might continue infinitely if there exists no path between the two nodes. I haven't tested all cases, YMMV.
from collections import deque
# a sample graph
graph = {'A': ['B', 'C','E'],
'B': ['A','C', 'D'],
'C': ['D'],
'D': ['C'],
'E': ['F','D'],
'F': ['C']}
def BFS(start, end):
""" Method to determine if a pair of vertices are connected using BFS
Args:
start, end: vertices for the traversal.
Returns:
[start, v1, v2, ... end]
"""
path = []
q = deque()
q.append(start)
while len(q):
tmp_vertex = q.popleft()
if tmp_vertex not in path:
path.append(tmp_vertex)
if tmp_vertex == end:
return path
for vertex in graph[tmp_vertex]:
if vertex not in path:
q.append(vertex)
DateTime.Ticks will account for the time. Use .Ticks on the DateTime to convert your dates into longs. Then just use a simple if stmt to see if your target date falls between.
// Assuming you know d2 > d1
if (targetDt.Ticks > d1.Ticks && targetDt.Ticks < d2.Ticks)
{
// targetDt is in between d1 and d2
}
EDIT: Changed the regular expression to exclude A-Z
Regular expression solution is the fastest pure python solution so far
reg=re.compile('^[a-z0-9\.]+$')
>>>reg.match('jsdlfjdsf12324..3432jsdflsdf')
True
>>> timeit.Timer("reg.match('jsdlfjdsf12324..3432jsdflsdf')", "import re; reg=re.compile('^[a-z0-9\.]+$')").timeit()
0.70509696006774902
Compared to other solutions:
>>> timeit.Timer("set('jsdlfjdsf12324..3432jsdflsdf') <= allowed", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()
3.2119350433349609
>>> timeit.Timer("all(c in allowed for c in 'jsdlfjdsf12324..3432jsdflsdf')", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()
6.7066690921783447
If you want to allow empty strings then change it to:
reg=re.compile('^[a-z0-9\.]*$')
>>>reg.match('')
False
Under request I'm going to return the other part of the answer. But please note that the following accept A-Z range.
You can use isalnum
test_str.replace('.', '').isalnum()
>>> 'test123.3'.replace('.', '').isalnum()
True
>>> 'test123-3'.replace('.', '').isalnum()
False
EDIT Using isalnum is much more efficient than the set solution
>>> timeit.Timer("'jsdlfjdsf12324..3432jsdflsdf'.replace('.', '').isalnum()").timeit()
0.63245487213134766
EDIT2 John gave an example where the above doesn't work. I changed the solution to overcome this special case by using encode
test_str.replace('.', '').encode('ascii', 'replace').isalnum()
And it is still almost 3 times faster than the set solution
timeit.Timer("u'ABC\u0131\u0661'.encode('ascii', 'replace').replace('.','').isalnum()", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()

In my opinion using regular expressions is the best to solve this problem
I've been using this little cheat for a while now. You might enjoy it. nest the table you want to center in another table:
<table height=100% width=100%>
<td align=center valign=center>
(add your table here)
</td>
</table>
the align and valign put the table exactly in the middle of the screen, no matter what else is going on.
This is the first post on google so I thought I'd post different ways that are available and how they compare. Unfortunately I can't figure out how to create a table here, so it's an image. The code for each is below the image using fully qualified names.
My.Application.Info.DirectoryPath
Environment.CurrentDirectory
System.Windows.Forms.Application.StartupPath
AppDomain.CurrentDomain.BaseDirectory
System.Reflection.Assembly.GetExecutingAssembly.Location

New System.UriBuilder(System.Reflection.Assembly.GetExecutingAssembly.CodeBase)
Path.GetDirectoryName(Uri.UnescapeDataString((New System.UriBuilder(System.Reflection.Assembly.GetExecutingAssembly.CodeBase).Path)))

I'm probably going a million miles in the wrong direct (but i'm only young :P ). but couldn't you add the graphic to a panel and then a mouselistener to the graphic object so that when the user on the graphic your action is preformed.
You can Enable DBMS_OUTPUT and set the buffer size. The buffer size can be between 1 and 1,000,000.
dbms_output.enable(buffer_size IN INTEGER DEFAULT 20000);
exec dbms_output.enable(1000000);
Check this
EDIT
As per the comment posted by Frank and Mat, you can also enable it with Null
exec dbms_output.enable(NULL);
buffer_size : Upper limit, in bytes, the amount of buffered information. Setting buffer_size to NULL specifies that there should be no limit. The maximum size is 1,000,000, and the minimum is 2,000 when the user specifies buffer_size (NOT NULL).
The use of _New is useful when working on pages that are Iframed. Since target="_blank" doesn't do the trick and opens the page on the same iframe... target new is the best solution for Iframe Pages. Just my five cents.
I had a problem with this kind of sql, I was giving empty list in IN clause(always check the list if it is not empty). Maybe my practice will help somebody.
There are many answers and all are correct as well. But unfortunately none of them have a clear explanation.
The following works for a non-primary key mapping as well.
Let's say we have parent table A with column 1 and another table, B, with column 2 which references column 1:
@ManyToOne
@JoinColumn(name = "TableBColumn", referencedColumnName = "TableAColumn")
private TableA session_UserName;
@ManyToOne
@JoinColumn(name = "bok_aut_id", referencedColumnName = "aut_id")
private Author bok_aut_id;
Use
substring_index(`column`,',',1) ==> first value
substring_index(substring_index(`column`,',',-2),',',1)=> second value
substring_index(substring_index(`column`,',',-1),',',1)=> third value
in your where clause.
SELECT * FROM `table`
WHERE
substring_index(`column`,',',1)<0
AND
substring_index(`column`,',',1)>5
Try this:
#foo
{
position: absolute;
top: 100%;
right: 0%;
}
Use dir(object). Or you can always download Firebug for Firefox (really helpful).
When using JavaScript to access an HTML element, there is a good chance that the element is not on the page and therefore not in the dom as far as JavaScript is concerned, when the code to access that element runs.
This problem can occur even though you can visually see the HTML element in the browser window or have the code set to be called in the onload method.
I ran into this problem after writing code to repopulate specific div elements on a page after retrieving the cookies.
What is apparently happening is that even though the HTML has loaded and is outputted by the browser, the JavaScript code is running before the page has completed loading.
The solution to this problem which just may be a JavaScript bug, is to place the code you want to run within a timer that delays the code run by 400 milliseconds or so. You will need to test it to determine how quick you can run the code.
I also made a point to test for the element before attempting to assign values to it.
window.setTimeout(function() {
if( document.getElementById("book") )
{ // Code goes here }, 400 /* but after 400 ms */);
This may or may not help you solve your problem, but keep this in mind and understand that browsers do not always function as expected.
appendChild()
is a more native way:
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'script.js';
document.head.appendChild(script);
Try this:
if(Math.floor(id) == id && $.isNumeric(id))
alert('yes its an int!');
$.isNumeric(id)
checks whether it's numeric or not
Math.floor(id) == id
will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.
This line means you instantiated a "List of ClientThread Objects".
private List<ClientThread> clients = new ArrayList<ClientThread>();
This line has two problems.
String hey = clients.get(clients.size());
1. This part of the line:
clients.get(clients.size());
ALWAYS throws IndexOutOfBoundsException because a collections size is always one bigger than its last elements index;
2. Compiler complains about incompatible types because you cant assign a ClientThread object to String object. Correct one should be like this.
ClientThread hey = clients.get(clients.size()-1);
Last but not least. If you know index of the object to remove just write
clients.remove(23); //Lets say it is in 23. index
Don't write
ClientThread hey = clients.get(23);
clients.remove(hey);
because you are forcing the list to search for the index that you already know. If you plan to do something with the removed object later. Write
ClientThread hey = clients.remove(23);
This way you can remove the object and get a reference to it at the same line.
Bonus: Never ever call your instance variable with name "hey". Find something meaningful.
And Here is your corrected and ready-to-run code:
public class ListExampleForDan {
private List<ClientThread> clients = new ArrayList<ClientThread>();
public static void main(String args[]) {
clients.add(new ClientThread("First and Last Client Thread"));
boolean success = removeLastElement(clients);
if (success) {
System.out.println("Last Element Removed.");
} else {
System.out.println("List Is Null/Empty, Operation Failed.");
}
}
public static boolean removeLastElement(List clients) {
if (clients == null || clients.isEmpty()) {
return false;
} else {
clients.remove(clients.size() - 1);
return true;
}
}
}
Enjoy!
Never ever use a "background color" for your listview rows...
this will block every selector action (was my problem!)
good luck!
I had the same error at first and i was really annoyed.
you just need to have ./
before the path to the template
res.render('./index/index');
Hope it works, worked for me.
I initially used IsNothing but I've been moving towards using Is Nothing in newer projects, mainly for readability. The only time I stick with IsNothing is if I'm maintaining code where that's used throughout and I want to stay consistent.
Like it was saying previously - you can access any parameters by using injection container and use its parameter property.
"Symfony - Working with Container Service Definitions" is a good article about it.
As for me, it was a stupid deployment mistake: Web projects can have more than one web.config. It was working on the developer's machine and not in production, but we were not realising that the deployment script only grabbed the Web.config
file at the root, and it didn't copy the Web.config
file in the Views
folder.
input[type='text'], input[type='password']
{
// my css
}
That is the correct way to do it. Sadly CSS is not a programming language.
Use sp_executesql
to execute any SQL, e.g.
DECLARE @tbl sysname,
@sql nvarchar(4000),
@params nvarchar(4000),
@count int
DECLARE tblcur CURSOR STATIC LOCAL FOR
SELECT object_name(id) FROM syscolumns WHERE name = 'LastUpdated'
ORDER BY 1
OPEN tblcur
WHILE 1 = 1
BEGIN
FETCH tblcur INTO @tbl
IF @@fetch_status <> 0
BREAK
SELECT @sql =
N' SELECT @cnt = COUNT(*) FROM dbo.' + quotename(@tbl) +
N' WHERE LastUpdated BETWEEN @fromdate AND ' +
N' coalesce(@todate, ''99991231'')'
SELECT @params = N'@fromdate datetime, ' +
N'@todate datetime = NULL, ' +
N'@cnt int OUTPUT'
EXEC sp_executesql @sql, @params, '20060101', @cnt = @count OUTPUT
PRINT @tbl + ': ' + convert(varchar(10), @count) + ' modified rows.'
END
DEALLOCATE tblcur

This assumes the exe is somewhere you know on the user's computer:

var SendInfo= { SendInfo: [... your elements ...]};
$.ajax({
type: 'post',
url: 'Your-URI',
data: JSON.stringify(SendInfo),
contentType: "application/json; charset=utf-8",
traditional: true,
success: function (data) {
...
}
});
and in action
public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...
you can bind your array like this
var SendInfo = [];
$(this).parents('table').find('input:checked').each(function () {
var domain = {
name: $("#id-manuf-name").val(),
address: $("#id-manuf-address").val(),
phone: $("#id-manuf-phone").val(),
}
SendInfo.push(domain);
});
hope this can help you.
Yet another way:
$('#elem').each(function(){
// do stuff
});
There is no implicit (automatic) cast from text
or varchar
to integer
(i.e. you cannot pass a varchar
to a function expecting integer
or assign a varchar
field to an integer
one), so you must specify an explicit cast using ALTER TABLE ... ALTER COLUMN ... TYPE ... USING:
ALTER TABLE the_table ALTER COLUMN col_name TYPE integer USING (col_name::integer);
Note that you may have whitespace in your text fields; in that case, use:
ALTER TABLE the_table ALTER COLUMN col_name TYPE integer USING (trim(col_name)::integer);
to strip white space before converting.
This shoud've been obvious from an error message if the command was run in psql
, but it's possible PgAdmin-III isn't showing you the full error. Here's what happens if I test it in psql
on PostgreSQL 9.2:
=> CREATE TABLE test( x varchar );
CREATE TABLE
=> insert into test(x) values ('14'), (' 42 ');
INSERT 0 2
=> ALTER TABLE test ALTER COLUMN x TYPE integer;
ERROR: column "x" cannot be cast automatically to type integer
HINT: Specify a USING expression to perform the conversion.
=> ALTER TABLE test ALTER COLUMN x TYPE integer USING (trim(x)::integer);
ALTER TABLE
Thanks @muistooshort for adding the USING
link.
See also this related question; it's about Rails migrations, but the underlying cause is the same and the answer applies.
If the error still occurs, then it may be related not to column values, but indexes over this column or column default values might fail typecast. Indexes need to be dropped before ALTER COLUMN and recreated after. Default values should be changed appropriately.
The Web API basically return 4 type of object: void
, HttpResponseMessage
, IHttpActionResult
, and other strong types. The first version of the Web API returns HttpResponseMessage
which is pretty straight forward HTTP response message.
The IHttpActionResult
was introduced by WebAPI 2 which is a kind of wrap of HttpResponseMessage
. It contains the ExecuteAsync()
method to create an HttpResponseMessage
. It simplifies unit testing of your controller.
Other return type are kind of strong typed classes serialized by the Web API using a media formatter into the response body. The drawback was you cannot directly return an error code such as a 404. All you can do is throwing an HttpResponseException
error.
typedef struct{
char array[4];
}my_array;
my_array array = { .array = {1,1,1,1} }; // initialisation
void assign(my_array a)
{
array.array[0] = a.array[0];
array.array[1] = a.array[1];
array.array[2] = a.array[2];
array.array[3] = a.array[3];
}
char num = 5;
char ber = 6;
int main(void)
{
printf("%d\n", array.array[0]);
// ...
// this works even after initialisation
assign((my_array){ .array = {num,ber,num,ber} });
printf("%d\n", array.array[0]);
// ....
return 0;
}
In SQL Server you can do this:
SELECT *
FROM (
SELECT ROW_NUMBER()
OVER(PARTITION BY customer
ORDER BY total DESC) AS StRank, *
FROM Purchases) n
WHERE StRank = 1
Explaination:Here Group by is done on the basis of customer and then order it by total then each such group is given serial number as StRank and we are taking out first 1 customer whose StRank is 1
This is a bit late but may help someone. Not sure if diff or rsync spit out just filenames in a bare format like this. Thanks to plhn for giving that nice solution which I expanded upon below.
If you want just the filenames so it's easy to just copy the files you need in a clean format, you can use the find command.
comm -23 <(find dir1 | sed 's/dir1/\//'| sort) <(find dir2 | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'
This assumes that both dir1 and dir2 are in the same parent folder. sed just removes the parent folder so you can compare apples with apples. The last sed just puts the dir1 name back.
If you just want files:
comm -23 <(find dir1 -type f | sed 's/dir1/\//'| sort) <(find dir2 -type f | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'
Similarly for directories:
comm -23 <(find dir1 -type d | sed 's/dir1/\//'| sort) <(find dir2 -type d | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'
For me this work for example here what happen is the main menu will be disabled when you open the registration form.
frmUserRegistration frmMainMenu = new frmUserRegistration();
frmMainMenu.ShowDialog(this);
Both of the examples are in VB.NET.
Debug path:
TextBox1.Text = My.Application.Info.DirectoryPath
EXE path:
TextBox2.Text = IO.Path.GetFullPath(Application.ExecutablePath)
As a sub form i think it's not gonna Start in the middle of the parent form until you Show it as a Dialog.
..........
Form2.ShowDialog();
i was about to make About Form. and this is perfect that's i am searching for. and untill you close the About_form you cant Touch/click anythings of parents Form once you Click for About_Form (in my case) .Coz its Showing as Dialog
You most likely mean "yyyy-MM-dd" small latter 'm' would imply minutes section.
You should do two things
add spring.jackson.serialization.write-dates-as-timestamps:false
in your application.properties
this will disable converting dates to timestamps and instead use a ISO-8601 compliant format
You can than customize the format by annotating the getter method of you dateOfBirth
property with @JsonFormat(pattern="yyyy-MM-dd")
For new line characters
UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);
For all white space characters
UPDATE table_name SET field_name = TRIM(field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\t' FROM field_name);

For most Microsoft products (Internet Explorer, Office, "open file" dialogs etc) you can register an application to be run when URI with appropriate prefix is opened. This is a part of more common explanation - how to implement your own protocol.
function insSubstr($str, $sub, $posStart, $posEnd){
return mb_substr($str, 0, $posStart) . $sub . mb_substr($str, $posEnd + 1);
}
Declaration says "this thing exists somewhere":
int foo(); // function
extern int bar; // variable
struct T
{
static int baz; // static member variable
};
Definition says "this thing exists here; make memory for it":
int foo() {} // function
int bar; // variable
int T::baz; // static member variable
Initialisation is optional at the point of definition for objects, and says "here is the initial value for this thing":
int bar = 0; // variable
int T::baz = 42; // static member variable
Sometimes it's possible at the point of declaration instead:
struct T
{
static int baz = 42;
};
…but that's getting into more complex features.
So a lot of complicated answers. The easiest way I can think of is to just give one of the elements a negative margin (either margin-left
or margin-right
depending on the position of the element).

You put your template in the wrong place. From the Flask docs:
Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates
I have created Delayed component using Hooks and TypeScript
import React, { useState, useEffect } from 'react';
type Props = {

waitBeforeShow?: number;
};
const Delayed = ({ children, waitBeforeShow = 500 }: Props) => {
const [isShown, setIsShown] = useState(false);
useEffect(() => {
setTimeout(() => {
setIsShown(true);
}, waitBeforeShow);
}, [waitBeforeShow]);
return isShown ? children : null;
};
export default Delayed;
Just wrap another component into Delayed

Given an activated Python 3.6 virtualenv in somepath/venv, the following aliases resolved the various issues on a macOS Sierra where pip insisted on pointing to Apple's 2.7 Python.
alias pip='python somepath/venv/lib/python3.6/site-packages/pip/__main__.py'
This didn't work so well when I had to do sudo pip
as the root user doesn't know anything about my alias or the virtualenv, so I had to add an extra alias to handle this as well. It's a hack, but it works, and I know what it does:
alias sudopip='sudo somepath/venv/bin/python somepath/venv/lib/python3.6/site-packages/pip/__main__.py'
pip3 did not exist to start (command not found) with and which pip
would return /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pip, the Apple Python.
Python 3.6 was installed via macports.
After activation of the 3.6 virtualenv I wanted to work with, which python
would return somepath/venv/bin/python
Somehow pip install
would do the right thing and hit my virtualenv, but pip list
would rattle off Python 2.7 packages.
For Python, this is batting way beneath my expectations in terms of beginner-friendliness.
You aren't supposed to change the folder attribute to not-readonly. The reason you are seeing this error message is that source control assumes that you only store your miscellaneous files somewhere other than bin folder, for it it reserved for files that are automatically created by .Net and it doesn't want to add them to source control.
I suggest instead of using Environment.CurrectDirectory
(which I assume you are using currently), you create a folder named "MyProjectName" in %appdata% address and then use:
System.IO.Path.Combine(Environment.GetEnvironmentVariable("appdata"),"YourProjectName")
.
Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories
, and it should work.
The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

Allow Xcode to do its work, do not add/create Swift header manually. Just add @objc before your Swift class ex.
@objc class YourSwiftClassName: UIViewController
In your project setting search for below flags and change it to YES (Both Project and Target)
Defines Module : YES
Always Embed Swift Standard Libraries : YES
Install Objective-C Compatibility Header : YES
Then clean the project and build once, after build succeed (it should probably) import below header file in your objective-c class .m file
#import "YourProjectName-Swift.h"
Boooom!
There's no such concept as an integer with padding. How many legs do you have - 2, 02 or 002? They're the same number. Indeed, even the "2" part isn't really part of the number, it's only relevant in the decimal representation.
If you need padding, that suggests you're talking about the textual representation of a number... i.e. a string.
You can achieve that using string formatting options, e.g.
string text = value.ToString("0000000");
or
string text = value.ToString("D7");
Your
<img src="/home/tony/london.jpg" />
will work for a HTML file read from disk, as it will assume the URL is file:///home/...
. For a file served from a webserver though, the URL will become something like: http://www.yourdomain.com/home/tony/london.jpg
, which can be an invalid URL and not what you really mean.
For about how to serve and where to place your static files, check out this document. Basicly, if you're using django's development server, you want to show him the place where your media files live, then make your urls.py
serve those files (for example, by using some /static/
url prefix).
Will require you to put something like this in your urls.py
:
(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
In production environment you want to skip this and make your http server (apache, lighttpd, etc) serve static files.
In case we want all the Person (instead of only one Person) in the returning dictionary, we could:
var _people = personList

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu". Once this is done, you can open an admin powershell window via Win+X,A or by right-clicking on the start button and selecting "Windows Powershell (Admin)":

Here's where you replace the "Command Prompt" option with a "Windows Powershell" option:
