I know this is an old post, but I just found this piece of gold. This is old (2006), but still works with IE9. I personnally added a bookmark with this.
Just copy paste this in your browser's address bar:
javascript:void(window.open("javascript:document.open(\"text/plain\");document.write(opener.document.body.parentNode.outerHTML)"))
As for firefox, web developper tool bar does the job. I usually use this, but sometimes, some dirty 3rd party asp.net controls generates differents markups based on the user agent...
EDIT
As Bryan pointed in the comment, some browser remove the javascript:
part when copy/pasting in url bar. I just tested and that's the case with IE10.
In my case the code to show e-mail client window caused Chrome to stop loading images:
document.location.href = mailToLink;
moving it to $(window).load(function () {...}) instead of $(function () {...}) helped.
Given a sample dataframe df
as:
a,b
1,2
2,3
3,4
4,5
what you want is:
df['a'] = df['a'].apply(lambda x: x + 1)
that returns:
a b
0 2 2
1 3 3
2 4 4
3 5 5
Thanks to both of you. This worked perfectly for me.

Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:
DirectoryIndex test.html
For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level
You can have it this way:
It is important to mind the commas after each struct item or set of items.

As of RC6 you can do the following to change URL without change state and thereby keeping your route history
import {OnInit} from '@angular/core';
import {Location} from '@angular/common';
// If you dont import this angular will import the wrong "Location"
@Component({
selector: 'example-component',
templateUrl: 'xxx.html'
})
export class ExampleComponent implements OnInit {
constructor( private location: Location )
{}
ngOnInit() {
this.location.replaceState("/some/newstate/");
}
}
You could try something like this:
#!/bin/bash
all_but()
{
target="$(git rev-parse $1)"
echo "$target --not"
git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
while read entry
do
eval "$entry"
test "$ref" != "$target" && echo "$ref"
done
}
git log $(all_but $1)
Or, borrowing from the recipe in the Git User's Manual:
#!/bin/bash
git log $1 --not $( git show-ref --heads | cut -d' ' -f2 | grep -v "^$1" )
Adding to the answer of Fatal Error, There is one more way to pass the variables to another shell script.
The above suggested solution have some drawbacks:
using Export
: It will cause the variable to be present out of their scope which is not a good design practice.using Source
: It may cause name collisions or accidental overwriting of a predefined variable in some other shell script file which have sourced another file.There is another simple solution avaiable for us to use. Considering the example posted by you,
test.sh
#!/bin/bash
TESTVARIABLE=hellohelloheloo
./test2.sh "$TESTVARIABLE"
test2.sh
#!/bin/bash
echo $1
output
hellohelloheloo
Also it is important to note that ""
are necessary if we pass multiword strings.
Taking one more example
master.sh
#!/bin/bash
echo in master.sh
var1="hello world"
sh slave1.sh $var1
sh slave2.sh "$var1"
echo back to master
slave1.sh
#!/bin/bash
echo in slave1.sh
echo value :$1
slave2.sh
#!/bin/bash
echo in slave2.sh
echo value : $1
output
in master.sh
in slave1.sh
value :"hello
in slave2.sh
value :"hello world"
It happens because of the reasons aptly described in this link
Both of these errors arise as a result of a provisioning profile not existing. To create one, simply do the following as suggested in the error message:
Verified: it works well in Docker 1.7.0.

From this thread on reference locally-built image using FROM at dockerfile:
If you want use the local image as the base image, pass without the option
--pull=true
--pull=true

If you plan on using Bootstrap 4 which is required with the angular-ui team's ng-bootstrap that is mentioned in this thread, you'll want to use this instead (NOTE: you don't need to include the JS file):

You can also reference this locally after running npm install [email protected] --save
by pointing to the file in your styles.scss
file, assuming you're using SASS:
@import '../../node_modules/bootstrap/dist/css/bootstrap.min.css';
Use the android.webkit.URLUtil

URLUtil.isValidUrl(URL_STRING);
Note: It is just checking the initial scheme of URL, not that the entire URL is valid.
Like you said, a jar is a zip file (not a special type, but just a plain old zip), so either library could be made to work. The reasoning is that the average person, seeing a *.zip extension, tends to unzip it. Since the app server wants it unzipped, a simple rename keeps people from unzipping it simply out of habit. Likewise, *.war file also should remain uncompressed.
java.util.jar basically just adds additional functionality to java.util.zip with very little extra overhead. Let the java.util.jar be a helper in posting, etc... and use it.

In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow
So i used:

build job: 'RunArtInTest', parameters: [[$class: 'StringParameterValue', name: 'systemname', value: systemname]]
}
Since the question is so popular, it may be useful to add on what to do if you want to control the type property name and its value.
The long way is to write custom JsonConverter
s to handle (de)serialization by manually checking and setting the type property.
A simpler way is to use JsonSubTypes, which handles all the boilerplate via attributes:
[JsonConverter(typeof(JsonSubtypes), "Sound")]
[JsonSubtypes.KnownSubType(typeof(Dog), "Bark")]
[JsonSubtypes.KnownSubType(typeof(Cat), "Meow")]
public class Animal
{
public virtual string Sound { get; }
public string Color { get; set; }
}
public class Dog : Animal
{
public override string Sound { get; } = "Bark";
public string Breed { get; set; }
}
public class Cat : Animal
{
public override string Sound { get; } = "Meow";
public bool Declawed { get; set; }
}
Well, you can't quite do it that way. PAGE.SIGN_CREATE
will never return 1; it will return PAGE.SIGN_CREATE
. That's the point of enumerated types.
However, if you're willing to add a few keystrokes, you can add fields to your enums, like this:
public enum PAGE{
SIGN_CREATE(0),
SIGN_CREATE_BONUS(1),
HOME_SCREEN(2),
REGISTER_SCREEN(3);
private final int value;
PAGE(final int newValue) {
value = newValue;
}
public int getValue() { return value; }
}
And then you call PAGE.SIGN_CREATE.getValue()
to get 0.
Yes, you can merge them using HTML. When I create tables in .md
files from Github, I always like to use HTML code instead of markdown.
Github Flavored Markdown supports basic HTML in .md
file. So this would be the answer:
Markdown mixed with HTML:
| Tables | Are | Cool |
| ------------- |:-------------:| -----:|
| col 3 is | right-aligned | $1600 |
| col 2 is | centered | $12 |
| zebra stripes | are neat | $1 |
| <ul><li>item1</li><li>item2</li></ul>| See the list | from the first column|
Or pure HTML:
<table>
<tbody>
<tr>
<th>Tables</th>
<th align="center">Are</th>
<th align="right">Cool</th>
</tr>
<tr>
<td>col 3 is</td>
<td align="center">right-aligned</td>
<td align="right">$1600</td>
</tr>
<tr>
<td>col 2 is</td>
<td align="center">centered</td>
<td align="right">$12</td>
</tr>
<tr>
<td>zebra stripes</td>
<td align="center">are neat</td>
<td align="right">$1</td>
</tr>
<tr>
<td>
<ul>
<li>item1</li>
<li>item2</li>
</ul>
</td>
<td align="center">See the list</td>
<td align="right">from the first column</td>
</tr>
</tbody>
</table>
This is how it looks on Github:
Use below CSS property
overscroll-behavior: contain;
to child element
Pick up a first sock and place it on a table. Now pick another sock; if it matches the first picked, place it on top of the first. If not, place it on the table a small distance from the first. Pick a third sock; if it matches either of the previous two, place it on top of them or else place it a small distance from the third. Repeat until you have picked up all the socks.
A simple way to see the key value pairs:
Map<String, Integer> map = new HashMap<>();
map.put("a", 1);
map.put("b", 2);
System.out.println(Arrays.asList(map)); // method 1
System.out.println(Collections.singletonList(map)); // method 2
Both method 1 and method 2 output this:
[{b=2, a=1}]

I'm surprised there's only one answer with an approach similar to the one I used.
I got the inspiration from @Dtipson's comment on @Mumthezir VP's answer.
I use two inputs for this, one is a fake input with type="text"
on which I set the placeholder, the other one is the real field with type="date"
.
On the mouseenter
event on their container, I hide the fake input and show the real one, and I do the opposite on the mouseleave
event. Obviously, I leave the real input visibile if it has a value set on it.
I wrote the code to use pure Javascript but if you use jQuery (I do) it's very easy to "convert" it.

I tested this also on an Android phone and it works, when the user taps on the field the datepicker is shown. The only thing is, if the real input had no value and the user closes the datepicker without choosing a date, the input will remain visible until they tap outside of it. There's no event to listen to to know when the datepicker closes so I don't know how to solve that.
I don't have an iOS device to test it on.

Had been wrecking my head on symlinking node .. and nothing seemed to work...but finally what worked is setting the right permissions . This 'sudo chown -R $(whoami) /usr/local' did the work for me.
I just needed to do this, but thought Steven's solution would be slow. This should hopefully use graphics HW. Create a category on UIImage:
- (UIImage *)imageByApplyingAlpha:(CGFloat) alpha {
UIGraphicsBeginImageContextWithOptions(self.size, NO, 0.0f);
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGRect area = CGRectMake(0, 0, self.size.width, self.size.height);
CGContextScaleCTM(ctx, 1, -1);
CGContextTranslateCTM(ctx, 0, -area.size.height);
CGContextSetBlendMode(ctx, kCGBlendModeMultiply);
CGContextSetAlpha(ctx, alpha);
CGContextDrawImage(ctx, area, self.CGImage);
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
According to Itzik Ben-Gan, author of T-SQL Fundamentals for MS SQL Server 2012, "By default, SQL Server sorts NULL marks before non-NULL values. To get NULL marks to sort last, you can use a CASE expression that returns 1 when the" Next_Contact_Date column is NULL, "and 0 when it is not NULL. Non-NULL marks get 0 back from the expression; therefore, they sort before NULL marks (which get 1). This CASE expression is used as the first sort column." The Next_Contact_Date column "should be specified as the second sort column. This way, non-NULL marks sort correctly among themselves." Here is the solution query for your example for MS SQL Server 2012 (and SQL Server 2014):
ORDER BY
CASE
WHEN Next_Contact_Date IS NULL THEN 1
ELSE 0
END, Next_Contact_Date;
Equivalent code using IIF syntax:
ORDER BY
IIF(Next_Contact_Date IS NULL, 1, 0),
Next_Contact_Date;

Here's what I did to slice out the "M":
s = 'EXAMPLE'
s1 = s[:s.index('M')] + s[s.index('M')+1:]
Here's my attempt:
I created a single-column (INTEGER
) table with no key:
CREATE TABLE a (a INTEGER NOT NULL);
Inserted integers in sequence starting at 1.
I stopped it (arbitrarily after many hours) when it had inserted 65,632,875 rows. The file size was 1,029,772 KB.
I compacted the file which reduced it very slightly to 1,029,704 KB.
I added a PK:
ALTER TABLE a ADD CONSTRAINT p PRIMARY KEY (a);
which increased the file size to 1,467,708 KB.
This suggests the maximum is somewhere around the 80 million mark.
If you are using the prawn gem for Ruby on Rails to generate your PDF, you can use the following additional gem to active the print dialog:
Your code snippet,
if number >= 10000 and number >= 30000:
print ("you have to pay 5% taxes")
actually checks if number is larger than both 10000 and 30000.
Assuming you want to check that the number is in the range 10000 - 30000, you could use the Python interval comparison:
if 10000 <= number <= 30000:
print ("you have to pay 5% taxes")
This Python feature is further described in the Python documentation.
While creating virtualenv if you use sudo the directory is created with root privileges.So when you try to install a package with non-sudo user you won't have permission to install into it. So always create virtualenv without sudo and install without sudo.
You can also copy packages installed on global python to virtualenv.
cp -r /lib/python/site-packages/* virtualenv/lib/python/site-packages/
Here is the package.json you will use for the master project:
"dependencies": {
"express": "*",
"somelocallib": "file:./somelocallib"
}
There, ./somelocallib
is the reference to the library folder as relative to the master project package.json.
Reference: https://docs.npmjs.com/files/package.json#local-paths
Handle your library dependencies.
In addition to running npm install
, you will need to run (cd node_modules/somelocallib && npm install)
.
This is a known bug with NPM.
Reference: https://github.com/npm/npm/issues/1341 (seeking a more up-to-date reference)
Check in your master package.lock
and your somelocallib/package.lock
into your source code manager.
Then in your Dockerfile use:
FROM node:10
WORKDIR /app
# ...
COPY ./package.json ./package-lock.json ./
COPY somelocallib somelocallib
RUN npm ci
RUN (cd node_modules/zkp-utils/ && npm ci)
# ...
I use parenthesis in my (cd A && B)
constructs to make the operation idempotent.
Update
Based on Manipulating the browser history, passing the empty string as second parameter of pushState
method (aka title) should be safe against future changes to the method, so it's better to use pushState
like this:
history.pushState(null, '', '/en/step2');
You can read more about that in mentioned article
Original Answer
Use history.pushState
like this:
history.pushState(null, null, '/en/step2');
Update 2 to answer Idan Dagan's comment:
Why not using
history.replaceState()
?
From MDN
history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one
That means if you use replaceState
, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState
doesn't add new entry to history) and it's not recommended and provide bad UX.
Update 3 to add window.onpopstate
So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState
, you can detect the back/forward button navigation by using window.onpopstate
like this:
window.onpopstate = function(e) {
// ...
};
As the first argument of pushState
is an object, if you passed an object
instead of null
, you can access that object in onpopstate
which is very handy, here is how:
window.onpopstate = function(e) {
if(e.state) {
console.log(e.state);
}
};
Update 4 to add Reading the current state:
When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate
event using the history.state
property like this:
console.log(history.state);
Bonus: Use following to check history.pushState
support:
if (history.pushState) {
// \o/
}
atos is being deprecated so if you are running OSX 10.9 or later you may need to run

To make it simple I will take the two versions of the code in keras and tf.keras. The example here is a simple Neural Network Model with different layers in it.
In Keras (v2.1.5)
from keras.models import Sequential
from keras.layers import Dense
def get_model(n_x, n_h1, n_h2):
model = Sequential()
model.add(Dense(n_h1, input_dim=n_x, activation='relu'))
model.add(Dense(n_h2, activation='relu'))
model.add(Dropout(0.5))
model.add(Dense(4, activation='softmax'))
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
print(model.summary())
return model
In tf.keras (v1.9)
import tensorflow as tf
def get_model(n_x, n_h1, n_h2):
model = tf.keras.Sequential()
model.add(tf.keras.layers.Dense(n_h1, input_dim=n_x, activation='relu'))
model.add(tf.keras.layers.Dense(n_h2, activation='relu'))
model.add(tf.keras.layers.Dropout(0.5))
model.add(tf.keras.layers.Dense(4, activation='softmax'))
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
print(model.summary())
return model
or it can be imported the following way instead of the above-mentioned way
from tensorflow.keras.layers import Dense
The official documentation of tf.keras
Note: TensorFlow Version is 1.9
Use below command at cmd or GIT Bash or other prompt
$ npm config set proxy "http://192.168.1.101:4128"
$ npm config set https-proxy "http://192.168.1.101:4128"
where 192.168.1.101 is proxy ip and 4128 is port. change according to your proxy settings. its works for me.
From what I learned after several days of research, Here is the Guide for ASP .Net Core MVC 2.x Custom User Authentication
In Startup.cs
:
Add below lines to ConfigureServices
method :
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(
CookieAuthenticationDefaults.AuthenticationScheme
).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
options =>
{
options.LoginPath = "/Account/Login";
options.LogoutPath = "/Account/Logout";
});
services.AddMvc();
// authentication
services.AddAuthentication(options =>
{
options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
});
services.AddTransient(
m => new UserManager(
Configuration
.GetValue<string>(
DEFAULT_CONNECTIONSTRING //this is a string constant
)
)
);
services.AddDistributedMemoryCache();
}
keep in mind that in above code we said that if any unauthenticated user requests an action which is annotated with [Authorize]
, they well force redirect to /Account/Login
url.
Add below lines to Configure
method :
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler(ERROR_URL);
}
app.UseStaticFiles();
app.UseAuthentication();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: DEFAULT_ROUTING);
});
}
Create your UserManager
class that will also manage login and logout. it should look like below snippet (note that i'm using dapper):
public class UserManager
{
string _connectionString;
public UserManager(string connectionString)
{
_connectionString = connectionString;
}
public async void SignIn(HttpContext httpContext, UserDbModel user, bool isPersistent = false)
{
using (var con = new SqlConnection(_connectionString))
{
var queryString = "sp_user_login";
var dbUserData = con.Query<UserDbModel>(
queryString,
new
{
UserEmail = user.UserEmail,
UserPassword = user.UserPassword,
UserCellphone = user.UserCellphone
},
commandType: CommandType.StoredProcedure
).FirstOrDefault();
ClaimsIdentity identity = new ClaimsIdentity(this.GetUserClaims(dbUserData), CookieAuthenticationDefaults.AuthenticationScheme);
ClaimsPrincipal principal = new ClaimsPrincipal(identity);
await httpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
}
}
public async void SignOut(HttpContext httpContext)
{
await httpContext.SignOutAsync();
}
private IEnumerable<Claim> GetUserClaims(UserDbModel user)
{
List<Claim> claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
claims.Add(new Claim(ClaimTypes.Name, user.UserFirstName));
claims.Add(new Claim(ClaimTypes.Email, user.UserEmail));
claims.AddRange(this.GetUserRoleClaims(user));
return claims;
}
private IEnumerable<Claim> GetUserRoleClaims(UserDbModel user)
{
List<Claim> claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
claims.Add(new Claim(ClaimTypes.Role, user.UserPermissionType.ToString()));
return claims;
}
}
Then maybe you have an AccountController
which has a Login
Action that should look like below :
public class AccountController : Controller
{
UserManager _userManager;
public AccountController(UserManager userManager)
{
_userManager = userManager;
}
[HttpPost]
public IActionResult LogIn(LogInViewModel form)
{
if (!ModelState.IsValid)
return View(form);
try
{
//authenticate
var user = new UserDbModel()
{
UserEmail = form.Email,
UserCellphone = form.Cellphone,
UserPassword = form.Password
};
_userManager.SignIn(this.HttpContext, user);
return RedirectToAction("Search", "Home", null);
}
catch (Exception ex)
{
ModelState.AddModelError("summary", ex.Message);
return View(form);
}
}
}
Now you are able to use [Authorize]
annotation on any Action
or Controller
.
Feel free to comment any questions or bug's.

Expanding on @Benav's answer, my preferred approach is to:
$(SolutionDir)
to the Additional Include DirectoriesNow you can include headers from your referenced projects like so:
#include "OtherProject/Header.h"
Notes:
#include
s, but it sets the correct build dependencies, which you probably want.i got same problem and i solved
gem update --system 3.0.6
defined?
is great, but if you are in a Rails environment you can also use try
, especially in cases where you want to check a dynamic variable name:
foo = 1
my_foo = "foo"
my_bar = "bar"
try(:foo) # => 1
try(:bar) # => nil
try(my_foo) # => 1
try(my_bar) # => nil
Better one is here.
$('#submit').click(function()
{
if( !$('#myMessage').val() ) {
alert('warning');
}
});
And you don't necessarily need .length or see if its >0 since an empty string evaluates to false anyway but if you'd like to for readability purposes:
$('#submit').on('click',function()
{
if( $('#myMessage').val().length === 0 ) {
alert('warning');
}
});
If you're sure it will always operate on a textfield element then you can just use this.value.
$('#submit').click(function()
{
if( !document.getElementById('myMessage').value ) {
alert('warning');
}
});
Also you should take note that $('input:text') grabs multiple elements, specify a context or use the this keyword if you just want a reference to a lone element ( provided theres one textfield in the context's descendants/children ).
CASE case_value
WHEN when_value THEN statements
[WHEN when_value THEN statements]
ELSE statements
END
Or:
CASE
WHEN <search_condition> THEN statements
[WHEN <search_condition> THEN statements]
ELSE statements
END
here CASE is an expression in 2nd scenario search_condition will evaluate and if no search_condition is equal then execute else
SELECT
CASE course_enrollment_settings.base_price
WHEN course_enrollment_settings.base_price = 0 THEN 1
should be
SELECT
CASE
WHEN course_enrollment_settings.base_price = 0 THEN 1
Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....
what difference does this make?
For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript
method:
Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.
But, if instead it was written like this (using the RegisterClientScriptBlock
method):
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
Focus will not get to the textbox control and a JavaScript error will be generated on the page
The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.
strtok
maintains a static, internal reference pointing to the next available token in the string; if you pass it a NULL pointer, it will work from that internal reference.
This is the reason strtok
isn't re-entrant; as soon as you pass it a new pointer, that old internal reference gets clobbered.
Swift 5 extension:
extension UIImageView{
func setImage(_ image: UIImage?, animated: Bool = true) {
let duration = animated ? 0.3 : 0.0
UIView.transition(with: self, duration: duration, options: .transitionCrossDissolve, animations: {
self.image = image
}, completion: nil)
}
}
db.example.updateMany({},{"$unset":{"tags.words":1}})
We can also use this to update multiple documents.
There is something called ksweb:
https://play.google.com/store/apps/details?id=ru.kslabs.ksweb&feature=search_result
String tmpHtml = "<html>a whole bunch of html stuff</html>";
String htmlTextStr = Html.fromHtml(tmpHtml).toString();
I see two things missing from the other answers:
canvas.toBlob
(when available) is more performant than canvas.toDataURL
, and also async.The following script deals with both points:
// From https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob, needed for Safari:
if (!HTMLCanvasElement.prototype.toBlob) {
Object.defineProperty(HTMLCanvasElement.prototype, 'toBlob', {
value: function(callback, type, quality) {
var binStr = atob(this.toDataURL(type, quality).split(',')[1]),
len = binStr.length,
arr = new Uint8Array(len);
for (var i = 0; i < len; i++) {
arr[i] = binStr.charCodeAt(i);
}
callback(new Blob([arr], {type: type || 'image/png'}));
}
});

This NSString
category uses the NSXMLParser
to accurately remove any HTML
tags from an NSString
. This is a single .m
and .h
file that can be included into your project easily.
https://gist.github.com/leighmcculloch/1202238
You then strip html
by doing the following:
Import the header:
#import "NSString_stripHtml.h"
And then call stripHtml:
NSString* mystring = @"<b>Hello</b> World!!";
NSString* stripped = [mystring stripHtml];
// stripped will be = Hello World!!
This also works with malformed HTML
that technically isn't XML
.
Subtract the beginning date from the end date:
endDate - beginDate
No, the errors occurs only after the Intelephense extension is automatically updated.
To solve the problem, you can downgrade it to the previous version by click "Install another version" in the Intelephense extension. There are no errors on version 1.2.3.
I found same problem, we can resolve in three steps:-
Step 1
sudo chown -R $(whoami) $(brew --prefix)/*
Step 2
brew doctor
Step 3
brew prune
If you still get any linking problem, lets say for mysql
, just write
brew link mysql
This will work.
First of all, don't use different encodings. It leads to a mess, and UTF-8 is definitely the one you should be using everywhere.
Chances are your input is not ISO-8859-1, but something else (ISO-8859-15, Windows-1252). To convert from those, use iconv or mb_convert_encoding
.
Nevertheless, utf8_encode
and utf8_decode
should work for ISO-8859-1. It would be nice if you could post a link to a file or a uuencoded or base64 example string for which the conversion fails or yields unexpected results.
"A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered."
Not so. The purpose of a destructor is to allow the item that registered the listeners to unregister them. Once an object has no other references to it, it will be garbage collected.
For instance, in AngularJS, when a controller is destroyed, it can listen for a destroy event and respond to it. This isn't the same as having a destructor automatically called, but it's close, and gives us the opportunity to remove listeners that were set when the controller was initialized.
// Set event listeners, hanging onto the returned listener removal functions
function initialize() {
$scope.listenerCleanup = [];
$scope.listenerCleanup.push( $scope.$on( EVENTS.DESTROY, instance.onDestroy) );
$scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.SUCCESS, instance.onCreateUserResponse ) );
$scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.FAILURE, instance.onCreateUserResponse ) );
}
// Remove event listeners when the controller is destroyed
function onDestroy(){
$scope.listenerCleanup.forEach( remove => remove() );
}
reduce(lambda x,y: mydict.get(y) and x.append(mydict[y]) or x, mykeys,[])
incase there are keys not in dict.
Note: I found this question looking for one of the steps in the answer to how to resize an existing array.
So I thought I would add that information here, in case anyone else was searching for how to do a ranged copy as a partial answer to the question of resizing an array.
For anyone else finding this question looking for the same thing I was, it is very simple:
Array.Resize<T>(ref arrayVariable, newSize);
where T is the type, i.e. where arrayVariable is declared:
T[] arrayVariable;
That method handles null checks, as well as newSize==oldSize having no effect, and of course silently handles the case where one of the arrays is longer than the other.
See the MSDN article for more.
You are absolutely correct. We cannot instantiate an abstract class because abstract methods don't have any body i.e. implementation is not possible for abstract methods. But there may be some scenarios where you want to initialize some variables of base class. You can do that by using base keyword as suggested by @Rodrick. In such cases, we need to use constructors in our abstract class.
Sort by picture and then by activity:
SELECT some_cols
FROM `prefix_users`
WHERE (some conditions)
ORDER BY pic_set, last_activity DESC;
With the latest iteration of netcoreapp 3.1 out, you can do this pretty simply without any third-party dependencies.
I created a gist for this, but you can use this class to read a JSON file and return dynamic properties.
using System.Text.Json;
using System.IO;
class ConfigurationLoader
{
private dynamic configJsonData;
public ConfigurationLoader Load(string configFilePath = "appsettings.json")
{
var appSettings = File.ReadAllText(configFilePath);
this.configJsonData = JsonSerializer.Deserialize(appSettings, typeof(object));
return this;
}
public dynamic GetProperty(string key)
{
var properties = key.Split(".");
dynamic property = this.configJsonData;
foreach (var prop in properties)
{
property = property.GetProperty(prop);
}
return property;
}
}
I specifically made this so I could use an appconfig.json in my dotnet console application. I just put this in my Program.Main
function:
var config = new ConfigurationLoader();
config.Load();
Console.WriteLine(config.GetProperty("Environment.Name"));
And this will return a dynamic
object for the property. (A JsonElement if it's not a primitive).
My appsettings.json
file looks like this:
{
"Environment": {
"Token": "abc-123",
"Name": "Production"
}
}
Before starting python, you can do in bash
export MPLBACKEND=TkAgg
I have found the other workaround: to exclude libinstrument.dylib
from project path. To do so, go to the Preferences -> Build, Execution and Deployment -> Compiler -> Excludes -> + and here add file by the path in error message.
this code works for all browsers and all inputs.
$('#your_target_input').attr('value', '');
this ought to work without you modifying the source csv file:
alter table people alter column age type text;
copy people from '/tmp/people.csv' with csv;
What I do when I mess up my local branch is I just rename my broken branch, and check out/branch the upstream branch again:
git branch -m branch branch-old
git fetch remote
git checkout -b branch remote/branch
Then if you're sure you don't want anything from your old branch, remove it:
git branch -D branch-old
But usually I leave the old branch around locally, just in case I had something in there.
Or you can try CGI.unescapeHTML method.
CGI.unescapeHTML "<p>This is a Paragraph.</p>"
=> "<p>This is a Paragraph.</p>"
A simple one would be
\d{4}-\d{2}-\d{2}
but this does not restrict month to 1-12 and days from 1 to 31.
There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.
As explained by this answer, the exact location of the string pool is not specified and can vary from one JVM implementation to another.
It is interesting to note that until Java 7, the pool was in the permgen space of the heap on hotspot JVM but it has been moved to the main part of the heap since Java 7:
Area: HotSpot
Synopsis: In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences. RFE: 6962931
And in Java 8 Hotspot, Permanent Generation has been completely removed.
Following may be one more alternate solution to concatenate multiple strings.
String str1 = "sometext";
string str2 = "some other text";
string afterConcate = $"{str1}{str2}";
For XCode 10, one may need to use the legacy build system

Depending on the encoding you wish to use:
var str = System.Text.Encoding.Default.GetString(result);
If you want to refresh the table without adding new data then use this:
First, create the API variable of your table like this:
var myTableApi = $('#mytable').DataTable(); // D must be Capital in this.
And then use refresh code wherever you want:
myTableApi.search(jQuery('input[type="search"]').val()).draw() ;
It will search data table with current search value (even if it's blank) and refresh data,, this work even if Datatable has server-side processing enabled.
There is a history in C of doing things like:
while (*a++ = *b++);
to copy a string, perhaps this is the source of the excessive trickery he is referring to.
And there's always the question of what
++i = i++;
or
i = i++ + ++i;
actually do. It's defined in some languages, and in other's there's no guarantee what will happen.
Those examples aside, I don't think there's anything more idiomatic than a for loop that uses ++
to increment. In some cases you could get away with a foreach loop, or a while loop that checked a different condtion. But contorting your code to try and avoid using incrementing is ridiculous.
The solution to this problem is as simple as eating a piece of cake.This issue generally arises when your user credentials change and SQL server is not able to identify you .No need to uninstall the existing SQL server instance .You can simply install a new instance with a new instance name . Lets say if your last instance name was 'Sqlexpress' , so this time during installation , name your instance as 'Sqlexpress1' . Also don't forget to select the mix mode (i.e Sql Server Authentication & Windows Authentication) during the installation and provide a system admin password which will be handy if such a problem occurs in future. This solution will definitely resolve this issue. Thanks..
Actually you have to Do Like below Example, which will help to Solve the Issue...
drop table ABC_table
create table ABC_table
(
names varchar(20),
age int
)
ALTER TABLE ABC_table
ADD CONSTRAINT MyConstraintName
DEFAULT 'This is not NULL' FOR names
insert into ABC(age) values(10)
select * from ABC
I'm disabling select2 with:
$('select').select2("enable",false);
And enabling it with
$('select').select2("enable");
You got a syntax wrong. Just pass in array's name. BTW - it's good idea to read some common formatting stuff too, for example in Java methods should start with lowercase letter (it's not an error it's convention)
Try
make clean
./configure --with-option=/path/etc
make && make install
You may use crudini
tool to get ini values, e.g.:
DATABASE_VERSION=$(crudini --get parameters.ini '' database_version)
FYI, the list of operators (containing like and all others) is in code:
/vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php
protected $operators = array(

'like', 'not like', 'between', 'ilike',
'&', '|', '^', '<<', '>>',
'rlike', 'regexp', 'not regexp',
);
disclaimer:
Joel Larson's answer is correct. Got my upvote.
I'm hoping this answer sheds more light on what's available via the Eloquent ORM (points people in the right direct). Whilst a link to documentation would be far better, that link has proven itself elusive.
If you want to study code how to setup a "Baseline" web application with ViewModels I can advise to download this code on GitHub: https://github.com/ajsaulsberry/BlipAjax. I developed large enterprise applications. When you do this its problematic to setup a good architecture that handles all this "ViewModel" functionality. I think with BlipAjax you will have a very Good "baseline" to start with. Its just a simple website, but great in its simplicity. I like the way they used the English language to point at whats really needed in the application.
First disable selinux (vim /etc/selinux/config)
vim /etc/httpd/conf/httpd.conf edit following lines for symlinks and directory indexing:
documentroot /var/www/html
<directory /var/www/html>
Options Indexes FollowSymLinks
AllowOverride None
</directory>
If .htaccess file then AllowOverride all
One nice way (without adding a fake .js extension which is for code not for data and configs) is to use json-loader
module. If you have used create-react-app
to scaffold your project, the module is already included, you just need to import your json:
import Profile from './components/profile';

I was facing the same issue. I was missing DriverManager.registerDriver() call, before getting the connection using the connection URL and user credentials.
It got fixed on Linux as below:
DriverManager.registerDriver(new org.apache.derby.jdbc.ClientDriver());
connection = DriverManager.getConnection("jdbc:derby://localhost:1527//tmp/Test/DB_Name", user, pass);
For Windows:
DriverManager.registerDriver(new org.apache.derby.jdbc.ClientDriver());
connection = DriverManager.getConnection("jdbc:derby://localhost:1527/C:/Users/Test/DB_Name", user, pass);
You could try adding an<hr>
and styling that. Its a minimal markup change but seems to need less css so that might do the trick.

You can use a single group for seconds/minutes. The following expression may suit your needs:
([0-9]+)\s*(seconds|minutes)
Seems to work fine.
If you have an empty BEGIN ... END block you might see
Msg 102, Level 15, State 1, Line 10 Incorrect syntax near 'END'.
When you upload a file using FileField
, the file will have a URL that you can use to point to the file and use HTML download
attribute to download that file you can simply do this.
models.py
The model.py looks like this
class CsvFile(models.Model):
csv_file = models.FileField(upload_to='documents')
views.py
#csv upload
class CsvUploadView(generic.CreateView):
model = CsvFile
fields = ['csv_file']
template_name = 'upload.html'
#csv download
class CsvDownloadView(generic.ListView):
model = CsvFile
fields = ['csv_file']
template_name = 'download.html'
Then in your templates.
#Upload template
upload.html
<div class="container">
<form action="#" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form.media }}
{{ form.as_p }}
<button class="btn btn-primary btn-sm" type="submit">Upload</button>
</form>
#download template
download.html
{% for document in object_list %}
<a href="{{ document.csv_file.url }}" download class="btn btn-dark float-right">Download</a>
{% endfor %}
I did not use forms, just rendered model but either way, FileField is there and it will work the same.
Those things are Compiler- and Platform-specific. Neither the C nor the C++ standard say anything about calling conventions except for extern "C"
in C++.
how does a caller know if it should free up the stack ?
The caller knows the calling convention of the function and handles the call accordingly.
At the call site, does the caller know if the function being called is a cdecl or a stdcall function ?
Yes.
How does it work ?
It is part of the function declaration.
How does the caller know if it should free up the stack or not ?
The caller knows the calling conventions and can act accordingly.
Or is it the linkers responsibility ?
No, the calling convention is part of a function's declaration so the compiler knows everything it needs to know.
If a function which is declared as stdcall calls a function(which has a calling convention as cdecl), or the other way round, would this be inappropriate ?
No. Why should it?
In general, can we say that which call will be faster - cdecl or stdcall ?
I don't know. Test it.

Using Eclipse key mapping inside Android Studio is the better choice. It will easily adapt to existing key structure. But all the new persons are using new shortcut key structures in Android Studio has. So we will learn and follow Android Studio itself contain shortcuts will help easily interact the team mates.
If you use Android Studio in Max OS X mean to follow the below link. It works for me. https://stackoverflow.com/a/30891985/2219406
If your clustered index consist from only those fields than the simple, fast and reliable option is to use IGNORE_DUP_KEY
If you create the Clustered index with IGNORE_DUP_KEY ON
Than you can just use:
INSERT INTO EmailsRecebidos (De, Assunto, Data) VALUES (@_DE, @_ASSUNTO, @_DATA)
This should be safe in all cases!
For this is important to understand the difference between Merge and Rebase.
Rebases are how changes should pass from the top of hierarchy downwards and merges are how they flow back upwards.

What you are trying to achieve is best done using the function's local arguments variable.
function foo() {
if (arguments.length === 0) {
//do something
}
if (arguments.length === 1) {
//do something else
}
}
foo(); //do something
foo('one'); //do something else
You can find a better explanation of how this works here.
I ran into this while programming a musicbox card generator. Started with different libraries but everytime there was a glitch somehow. The lag on normal audio implementation was bad, no multiple plays... eventually ended up using lowlag library + soundmanager:
http://lowlag.alienbill.com/ and http://www.schillmania.com/projects/soundmanager2/
You can check out the implementation here: http://musicbox.grit.it/
I generated wav + ogg files for multi browser plays. This musicbox player works responsive on ipad, iphone, Nexus, mac, pc,... works for me.
An abstract class can have shared state or functionality. An interface is only a promise to provide the state or functionality. A good abstract class will reduce the amount of code that has to be rewritten because it's functionality or state can be shared. The interface has no defined information to be shared
EF does not require a primary key on the database. If it did, you couldn't bind entities to views.
You can modify the SSDL (and the CSDL) to specify a unique field as your primary key. If you don't have a unique field, then I believe you are hosed. But you really should have a unique field (and a PK), otherwise you are going to run into problems later.

In fact mentioned methods don't generate real random char. To generate real random char you should give it a random seed! in example time in millisecond. this code generate 10 random char and then Convert it to String:
import java.util.Random;
public class MyClass {
public static void main() {
String randomKey;
char[] tempArray={0,0,0,0,0,0,0,0,0,0}; //ten characters
long seed=System.currentTimeMillis();
Random random=new Random(seed);
for (int aux=0; aux<10;aux++){
tempArray[aux]=(char) random.nextInt(255);
System.out.println(tempArray[aux]);
}
randomKey=String.copyValueOf(tempArray);
System.out.println(randomKey);
}
}
You shall pass a this
pointer to tell the function which object to work on because it relies on that as opposed to a static
member function.

This is an old question, and there are many answers, most of which will be more or less helpful; however, there is one, very important and still relevant point, which none of the answers touch (providing, instead, different hacks to make build possible), and which, I think, in no way has a less importance.. on the contrary.
According to your log message, you are using Maven, which is a Project Management tool, firmly following the conventions, over configuration principle.
When Maven builds the project:
Maven's Standard Directory Layout
;Sun Microsystems Directory Structure Standard
for Java EE [web] applications.You may incorporate many things, including maven plugins, changing/reconfiguring project root directory, etc., but better and easier is to follow the default conventions over configuration, according to which, (now is the answer to your problem) there is one simple step that can make your project work: Just place your web.xml
under src\main\webapp\WEB-INF\
and try to build the project with mvn package
.

In C++11 and above, you can also initialize std::vector
with an initializer list. For example:
using namespace std; // for example only
for (auto s : vector<string>{"one","two","three"} )
cout << s << endl;
So, your example would become:
void foo(vector<string> strArray){
// some code
}
vector<string> s {"hi", "there"}; // Works
foo(s); // Works
foo(vector<string> {"hi", "there"}); // also works
If you want it to start at 000001

The answer is yes, if you write return statement the controls goes back to to the caller method immediately. With an exception of finally block, which gets executed after the return statement.
and finally can also override the value you have returned, if you return inside of finally block. LINK: Try-catch-finally-return clarification
Return Statement definition as per:
Java Docs:
a return statement can be used to branch out of a control flow block and exit the method
MSDN Documentation:
The return statement terminates the execution of a function and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call.
Wikipedia:
A return statement causes execution to leave the current subroutine and resume at the point in the code immediately after where the subroutine was called, known as its return address. The return address is saved, usually on the process's call stack, as part of the operation of making the subroutine call. Return statements in many languages allow a function to specify a return value to be passed back to the code that called the function.

Sushicutta's steps 4-7 can be skipped by adding the following line to step 3:
-Dcom.sun.management.jmxremote.rmi.port=<same port as jmx-remote-port>
e.g. Add to start up parameters:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.rmi.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=localhost
For the port forwarding, connect using:
ssh -L 12345:localhost:12345 <username>@<host>
if your host is a stepping stone, simply chain the port forward by running the following on the step stone after the above:
ssh -L 12345:localhost:12345 <username>@<host2>
Mind that the hostname=localhost is needed to make sure the jmxremote is telling the rmi connection to use the tunnel. Otherwise it might try to connect directy and hit the firewall.

Following the documentation of fopen
:
``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.
So if you pFile2=fopen("myfile2.txt", "a");
the stream is positioned at the end to append automatically. just do:
FILE *pFile;
FILE *pFile2;
char buffer[256];
pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
perror("Error opening file.");
}
else {
while(fgets(buffer, sizeof(buffer), pFile)) {
fprintf(pFile2, "%s", buffer);
}
}
fclose(pFile);
fclose(pFile2);
I got this same error when installing to an actual device. More information and a solution to loading the missing libraries to the device can be found at the following site:
Fixing the INSTALL_FAILED_MISSING_SHARED_LIBRARY Error
To set this up correctly, there are 2 key files that need to be copied to the system:
com.google.android.maps.xml
com.google.android.maps.jar
These files are located in the any of these google app packs:
http://android.d3xt3...0120-signed.zip
http://goo-inside.me...0120-signed.zip
http://android.local...0120-signed.zip
These links no longer work, but you can find the files in the android sdk if you have Google Maps API v1
After unzipping any of these files, you want to copy the files to your system, like-ah-so:
adb remount
adb push system/etc/permissions/com.google.android.maps.xml /system/etc/permissions
adb push system/framework/com.google.android.maps.jar /system/framework
adb reboot
The expression:
($min <= $value) && ($value <= $max)
will be true if $value
is between $min
and $max
, inclusively
See the PHP docs for more on comparison operators
According to the widget's page, it should be:
var myDropDownListValues = $("#myDropDownList").multiselect("getChecked").map(function()
{
return this.value;
}).get();
It works for me :)
First Close your project.
Open a Text File then Add target=android-your_Api_Level
.
Such as: target=android-7
And then Save that file as project.properties
Then manually place project.properties file into your Project's Folder and then Reopen you project.
The file generally looks like:
# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "ant.properties", and override values to adapt the script to your
# project structure.
# Project target.
target=android-7

There is a lack of answers for windows users. Here is how I solved this issue.
First add the PostgreSQL bin folder into the path variable like this
set PATH=%PATH%;C:\Program Files\PostgreSQL\11\bin
Substitute \11\
with your version of Postgres
next run
pip install pyscopg2
this at least got me to a compiling error.
Update: it looks to be an issue with the psycopg2 library and it’s dependencies not playing nice with python 3.8. https://github.com/psycopg/psycopg2/issues/990
Here's a data.table
solution that will list the duplicates along with the number of duplications (will be 1 if there are 2 copies, and so on - you can adjust that to suit your needs):
library(data.table)
dt = data.table(vocabulary)
dt[duplicated(id), cbind(.SD[1], number = .N), by = id]
Perhaps you're not disposing of the previous connection/ result classes from the previous run which means their still hanging around in memory.
Based on this SO answer, I just had to change path="*."
to path="*"
for the added ExtensionlessUrlHandler-Integrated-4.0
in configuration>system.WebServer>handlers
in my web.config
Before:
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
After:
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*" verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
I found this more useful for getting the absolute file location.
File file = new File("\\TestHello\\test.txt");
System.out.println(file.getAbsoluteFile());
var time = 0;
var time_framerate = 1000; //in milliseconds

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo rm -rf /var/lib/mysql
I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!
Use git checkout
instead of git stash apply
:
$ git checkout stash -- .
$ git commit
This will restore all the files in the current directory to their stashed version.
If there are changes to other files in the working directory that should be kept, here is a less heavy-handed alternative:
$ git merge --squash --strategy-option=theirs stash
If there are changes in the index, or the merge will touch files with local changes, git will refuse to merge. Individual files can be checked out from the stash using
$ git checkout stash -- <paths...>
or interactively with
$ git checkout -p stash
You can change the value of a bool all you want. As for an if:
if randombool == True:
works, but you can also use:
if randombool:
If you want to test whether something is false you can use:
if randombool == False
but you can also use:
if not randombool:

I am placing JLBorges's excellent response to a similar question verbatim from cplusplus.com, as it is the most succinct explanation I've read on the subject.
In a template that we write, there are two kinds of names that could be used - dependant names and non- dependant names. A dependant name is a name that depends on a template parameter; a non-dependant name has the same meaning irrespective of what the template parameters are.
For example:
template< typename T > void foo( T& x, std::string str, int count ) { // these names are looked up during the second phase // when foo is instantiated and the type T is known x.size(); // dependant name (non-type) T::instance_count ; // dependant name (non-type) typename T::iterator i ; // dependant name (type) // during the first phase, // T::instance_count is treated as a non-type (this is the default) // the typename keyword specifies that T::iterator is to be treated as a type. // these names are looked up during the first phase std::string::size_type s ; // non-dependant name (type) std::string::npos ; // non-dependant name (non-type) str.empty() ; // non-dependant name (non-type) count ; // non-dependant name (non-type) }
What a dependant name refers to could be something different for each different instantiation of the template. As a consequence, C++ templates are subject to "two-phase name lookup". When a template is initially parsed (before any instantiation takes place) the compiler looks up the non-dependent names. When a particular instantiation of the template takes place, the template parameters are known by then, and the compiler looks up dependent names.
During the first phase, the parser needs to know if a dependant name is the name of a type or the name of a non-type. By default, a dependant name is assumed to be the name of a non-type. The typename keyword before a dependant name specifies that it is the name of a type.

Use the keyword typename only in template declarations and definitions provided you have a qualified name that refers to a type and depends on a template parameter.

Your answer is Wi-Fi direct which is made available with ICS. Here is a link for explanation in Android doc
Do not simplify the code to avoid "linq translation error": The test consist between a date with time at 0:0:0 and the same date with time at 23:59:59
iFilter.MyDate1 = DateTime.Today; // or DateTime.MinValue
// GET
var tempQuery = ctx.MyTable.AsQueryable();
if (iFilter.MyDate1 != DateTime.MinValue)
{
TimeSpan temp24h = new TimeSpan(23,59,59);
DateTime tempEndMyDate1 = iFilter.MyDate1.Add(temp24h);
// DO not change the code below, you need 2 date variables...
tempQuery = tempQuery.Where(w => w.MyDate2 >= iFilter.MyDate1
&& w.MyDate2 <= tempEndMyDate1);
}
List<MyTable> returnObject = tempQuery.ToList();
You are consuming a line at, which is discarded
while((str=input.readLine())!=null && str.length()!=0)
and reading a bigint at
BigInteger n = new BigInteger(input.readLine());
so try getting the bigint from string which is read as
BigInteger n = new BigInteger(str);
Constructor used: BigInteger(String val)
Aslo change while((str=input.readLine())!=null && str.length()!=0)
to
while((str=input.readLine())!=null)
see related post string to bigint
readLine()
Returns:
A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached
see javadocs
If you are able to use org.apache.commons.lang.StringUtils, I suggest using the following:
String container = "aBcDeFg";
String content = "dE";
boolean containerContainsContent = StringUtils.containsIgnoreCase(container, content);
The JavaScript function:
String.prototype.capitalize = function(){
return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
};
To use this function:
capitalizedString = someString.toLowerCase().capitalize();
Also, this would work on multiple words string.
To make sure the converted City name is injected into the database, lowercased and first letter capitalized, then you would need to use JavaScript before you send it over to server side. CSS simply styles, but the actual data would remain pre-styled. Take a look at this jsfiddle example and compare the alert message vs the styled output.
This is the solution for your problem:
//Fetch page URL by this
$url = $_SERVER['REQUEST_URI'];
echo "$url<br />";
//It will print
//fetch host by this
$host=$_SERVER['HTTP_HOST'];
echo "$host<br />";
//You can fetch the full URL by this
$fullurl = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $fullurl;
There are already many good answers to this question, but they often require tweaks to work properly with notebooks in JupyterLab. I wrote this answer to detail the possible ways of including a ToC in a notebook while working in and exporting from JupyterLab.
The jupyterlab-toc extension adds the ToC as a side panel that can number headings, collapse sections, and be used for navigation (see gif below for a demo). This extension is included by default since JupyterLab 3.0, in older version you can install it with the following command
jupyter labextension install @jupyterlab/toc
At the time being, this can either be done manually as in Matt Dancho's answer, or automatically via the toc2 jupyter notebook extension in the classic notebook interface.
First, install toc2 as part of the jupyter_contrib_nbextensions bundle:
conda install -c conda-forge jupyter_contrib_nbextensions
Then,
launch JupyterLab,
go to Help --> Launch Classic Notebook
,
and open the notebook in which you want to add the ToC.
Click the toc2 symbol in the toolbar
to bring up the floating ToC window
(see the gif below if you can't find it),
click the gear icon and check the box for
"Add notebook ToC cell".
Save the notebook and the ToC cell will be there
when you open it in JupyterLab.
The inserted cell is a markdown cell with html in it,
it will not update automatically.
The default options of the toc2 can be configured in the "Nbextensions" tab in the classic notebook launch page. You can e.g. choose to number headings and to anchor the ToC as a side bar (which I personally think looks cleaner).
nbconvert
can be used to export notebooks to HTML
following rules of how to format the exported HTML.
The toc2
extension mentioned above adds an export format called html_toc
,
which can be used directly with nbconvert
from the command line
(after the toc2
extension has been installed):
jupyter nbconvert file.ipynb --to html_toc
# Append `--ExtractOutputPreprocessor.enabled=False`
# to get a single html file instead of a separate directory for images
Remember that shell commands can be added to notebook cells
by prefacing them with an exclamation mark !
,
so you can stick this line in the last cell of the notebook
and always have an HTML file with a ToC generated
when you hit "Run all cells"
(or whatever output you desire from nbconvert
).
This way,
you could use jupyterlab-toc
to navigate the notebook while you are working,
and still get ToCs in the exported output
without having to resort to using the classic notebook interface
(for the purists among us).
Note that configuring the default toc2 options
as described above,
will not change the format of nbconver --to html_toc
.
You need to open the notebook in the classic notebook interface
for the metadata to be written to the .ipynb file
(nbconvert reads the metadata when exporting)
Alternatively,
you can add the metadata manually
via the Notebook tools tab of the JupyterLab sidebar,
e.g. something like:
"toc": {
"number_sections": false,
"sideBar": true
}
If you prefer a GUI-driven approach,
you should be able to open the classic notebook
and click File --> Save as HTML (with ToC)
(although note that this menu item was not available for me).
The gifs above are linked from the respective documentation of the extensions.
After searching for "trouble upgrading git on mac" on Google, I read several posts and attempted the following before resolving the problem by completing step 4:
I updated my terminal path by using the above mention export command. Every time I quit the terminal and restarted it, when I typed git --version
the terminal, it still return the older version 1.8.
I followed the README.txt instructions for upgrading to the current version 2.0.1 that comes with the .dmg installer and when I restarted the terminal, still no go.
I looked for /etc/path/ folder as instructed above and the directory called "path" does not exist on my Mac. I am running OS X Mavericks version 10.9.4.
Then I recalled I have Homebrew installed on my Mac and ran the following:
brew --version
brew update
brew search git
brew install git
This finally resolved my problem. If anyone has some insight as to why this worked, further insight would be greatly appreciated. I probably have some left over path settings on my system from working with Ruby last year.
You return four variables s1,s2,s3,s4 and receive them using a single variable obj
. This is what is called a tuple
, obj
is associated with 4 values, the values of s1,s2,s3,s4
. So, use index as you use in a list to get the value you want, in order.
obj=list_benefits()
print obj[0] + " is a benefit of functions!"
print obj[1] + " is a benefit of functions!"
print obj[2] + " is a benefit of functions!"
print obj[3] + " is a benefit of functions!"

I was also wondering about the performance issue, and was hoping this would be optimised out by the compiler, based on the answer from @EmileCormier. However, I was worried that the test code he showed would still allow the compiler to optimise away the std::pow() call, since the same values were used in the call every time, which would allow the compiler to store the results and re-use it in the loop - this would explain the almost identical run-times for all cases. So I had a look into it too.
Here's the code I used (test_pow.cpp):
#include <iostream>
#include <cmath>
#include <chrono>
class Timer {
public:
explicit Timer () : from (std::chrono::high_resolution_clock::now()) { }
void start () {
from = std::chrono::high_resolution_clock::now();
}
double elapsed() const {
return std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::high_resolution_clock::now() - from).count() * 1.0e-6;
}
private:
std::chrono::high_resolution_clock::time_point from;
};
int main (int argc, char* argv[])
{
double total;
Timer timer;
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += std::pow (i,2);
std::cout << "std::pow(i,2): " << timer.elapsed() << "s (result = " << total << ")\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += i*i;
std::cout << "i*i: " << timer.elapsed() << "s (result = " << total << ")\n";
std::cout << "\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += std::pow (i,3);
std::cout << "std::pow(i,3): " << timer.elapsed() << "s (result = " << total << ")\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += i*i*i;
std::cout << "i*i*i: " << timer.elapsed() << "s (result = " << total << ")\n";
return 0;
}
This was compiled using:
g++ -std=c++11 [-O2] test_pow.cpp -o test_pow
Basically, the difference is the argument to std::pow() is the loop counter. As I feared, the difference in performance is pronounced. Without the -O2 flag, the results on my system (Arch Linux 64-bit, g++ 4.9.1, Intel i7-4930) were:
std::pow(i,2): 0.001105s (result = 3.33333e+07)
i*i: 0.000352s (result = 3.33333e+07)
std::pow(i,3): 0.006034s (result = 2.5e+07)
i*i*i: 0.000328s (result = 2.5e+07)
With optimisation, the results were equally striking:
std::pow(i,2): 0.000155s (result = 3.33333e+07)
i*i: 0.000106s (result = 3.33333e+07)
std::pow(i,3): 0.006066s (result = 2.5e+07)
i*i*i: 9.7e-05s (result = 2.5e+07)
So it looks like the compiler does at least try to optimise the std::pow(x,2) case, but not the std::pow(x,3) case (it takes ~40 times longer than the std::pow(x,2) case). In all cases, manual expansion performed better - but particularly for the power 3 case (60 times quicker). This is definitely worth bearing in mind if running std::pow() with integer powers greater than 2 in a tight loop...
The other answers here fail to spell out a full solution for regex versions which don't support non-greedy matching. The greedy quantifiers (.*?
, .+?
etc) are a Perl 5 extension which isn't supported in traditional regular expressions.
If your stopping condition is a single character, the solution is easy; instead of
a(.*?)b
you can match
a[^ab]*b
i.e specify a character class which excludes the starting and ending delimiiters.
In the more general case, you can painstakingly construct an expression like
start(|[^e]|e(|[^n]|n(|[^d])))end
to capture a match between start
and the first occurrence of end
. Notice how the subexpression with nested parentheses spells out a number of alternatives which between them allow e
only if it isn't followed by nd
and so forth, and also take care to cover the empty string as one alternative which doesn't match whatever is disallowed at that particular point.
Of course, the correct approach in most cases is to use a proper parser for the format you are trying to parse, but sometimes, maybe one isn't available, or maybe the specialized tool you are using is insisting on a regular expression and nothing else.
I'd like to recommend var_export($array)
- it doesn't show types, but it generates syntax you can use in your code :)
Check this simple program to understand int.TryParse
class Program
{
static void Main()
{
string str = "7788";
int num1;
bool n = int.TryParse(str, out num1);
Console.WriteLine(num1);
Console.ReadLine();
}
}
Output is : 7788
SQL Server R2 2008 needs the AS
clause as follows:
SELECT *
INTO #temp
FROM (
SELECT col1, col2
FROM table1
) AS x
The query failed without the AS x
at the end.
It's also needed when using SS2016, had to add as t
to the end.
Select * into #result from (SELECT * FROM #temp where [id] = @id) as t //<-- as t
What about Date.today.to_time

Assuming userInfoList
is a List<UserInfo>
:
var groups = userInfoList
.GroupBy(n => n.metric)
.Select(n => new
{
MetricName = n.Key,
MetricCount = n.Count()
}
)
.OrderBy(n => n.MetricName);
The lambda function for GroupBy()
, n => n.metric
means that it will get field metric
from every UserInfo
object encountered. The type of n
is depending on the context, in the first occurrence it's of type UserInfo
, because the list contains UserInfo
objects. In the second occurrence n
is of type Grouping
, because now it's a list of Grouping
objects.
Grouping
s have extension methods like .Count()
, .Key()
and pretty much anything else you would expect. Just as you would check .Lenght
on a string
, you can check .Count()
on a group.
In kotlin don't use getters and setters as like in java.The correct format of the kotlin is given below.
val textView: TextView = findViewById(R.id.android_text) as TextView
textView.setOnClickListener {
textView.text = getString(R.string.name)
}
To get the values from the Textview
we have to use this method
val str: String = textView.text.toString()
println("the value is $str")

I'm loading the PDF with jQuery ajax into browser cache. Then I create embedded element with data already in browser cache. I guess it will work with iframe too.
var url = "http://example.com/my.pdf";
// show spinner
$.mobile.showPageLoadingMsg('b', note, false);
$.ajax({
url: url,
cache: true,
mimeType: 'application/pdf',
success: function () {
// display cached data
$(scroller).append('<embed type="application/pdf" src="' + url + '" />');
// hide spinner
$.mobile.hidePageLoadingMsg();
}
});
You have to set your http headers correctly as well.
HttpContext.Response.Expires = 1;
HttpContext.Response.Cache.SetNoServerCaching();
HttpContext.Response.Cache.SetAllowResponseInBrowserHistory(false);
HttpContext.Response.CacheControl = "Private";
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.
The correct way to do it is to provide a docstring. That way, help(add)
will also spit out your comment.
def add(self):
"""Create a new user.
Line 2 of comment...
And so on...
"""
That's three double quotes to open the comment and another three double quotes to end it. You can also use any valid Python string. It doesn't need to be multiline and double quotes can be replaced by single quotes.
See: PEP 257
If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the complete result set regardless of what you selected
Highlight an interface and use Ctrl+T to open "Quick Type Hierarchy".
You can also copy the link address and paste it in a new window to get around the security. This works in chrome and firefox but you may have to add slashes in firefox.

@Lauren?iu Dascalu's answer explains how / why you get a ClassCastException.
Your exception message looks rather suspicious to me, but it might help you to know that "[Lcom.rsa.authagent.authapi.realmstat.AUTHw" means that the actual type of the object that you were trying to cast was com.rsa.authagent.authapi.realmstat.AUTHw[]
; i.e. it was an array object.

You can't define width/height/margins/... using percents in your XML. But what you would want to use is the "weight" attribute, which is, IMO, the most similar thing.
Another method would be to set the sizes programmatically after you inflate the layout in your code, by getting the size of your screen and calculating needed margins.
Had the same issue; validated HTML & found I was missing a name="email"
attribute from an <input />
. Always validate the HTML to be positive your HTML is valid. After I added it, validate()
worked perfectly.
You need to use the ui.item.label (the text) and ui.item.value (the id) properties
$('#selector').autocomplete({
source: url,
select: function (event, ui) {
$("#txtAllowSearch").val(ui.item.label); // display the selected text
$("#txtAllowSearchID").val(ui.item.value); // save selected id to hidden input
}
});
$('#button').click(function() {
alert($("#txtAllowSearchID").val()); // get the id from the hidden input
});
[Edit] You also asked how to create the multi-dimensional array...
You should be able create the array like so:
var $local_source = [[0,"c++"], [1,"java"], [2,"php"], [3,"coldfusion"],
[4,"javascript"], [5,"asp"], [6,"ruby"]];
Read more about how to work with multi-dimensional arrays here: http://www.javascriptkit.com/javatutors/literal-notation2.shtml
Whatever method you choose is not freeing you from performing the same validation on at the back end.
Look at the following code
$("#clickMe").click(function (e) {
var $this = $(this);
if ($this.hasClass('clicked')){
alert("Double click");
//here is your code for double click
return;
}else{
$this.addClass('clicked');
//your code for single click
setTimeout(function() {
$this.removeClass('clicked'); },500);
}//end of else
});

At the Maven repo, there are samples to add the dependency in maven, sbt, gradle, etc.
https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore/4.4.11
ie for Maven, you just create a project, for example
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
then look at the pom.xml, then at the library at the dependencies xml element:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>4.4.11</version>
</dependency>
For sbt do something like
sbt new scala/hello-world.g8
then edit the build.sbt to add the library
libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"
You need to specify the primary key as auto-increment
CREATE TABLE `momento_distribution`
(
`momento_id` INT(11) NOT NULL AUTO_INCREMENT,
`momento_idmember` INT(11) NOT NULL,
`created_at` DATETIME DEFAULT NULL,
`updated_at` DATETIME DEFAULT NULL,
`unread` TINYINT(1) DEFAULT '1',
`accepted` VARCHAR(10) NOT NULL DEFAULT 'pending',
`ext_member` VARCHAR(255) DEFAULT NULL,
PRIMARY KEY (`momento_id`, `momento_idmember`),
KEY `momento_distribution_FI_2` (`momento_idmember`),
KEY `accepted` (`accepted`, `ext_member`)
)
ENGINE=InnoDB
DEFAULT CHARSET=latin1$$
With regards to comment below, how about:
ALTER TABLE `momento_distribution`
CHANGE COLUMN `id` `id` INT(11) NOT NULL AUTO_INCREMENT,
DROP PRIMARY KEY,
ADD PRIMARY KEY (`id`);
A PRIMARY KEY is a unique index, so if it contains duplicates, you cannot assign the column to be unique index, so you may need to create a new column altogether
Try doubling up the single quotes (many databases expect it that way), so it would be :
INSERT INTO table_name (field1, field2) VALUES (123, 'Hello there''s');
Relevant quote from the documentation:
A string constant is formed by enclosing the string in single quotes ('). A single quote within the string can be encoded by putting two single quotes in a row - as in Pascal. C-style escapes using the backslash character are not supported because they are not standard SQL. BLOB literals are string literals containing hexadecimal data and preceded by a single "x" or "X" character. ... A literal value can also be the token "NULL".
Overall, the conventions are “think like you're just delivering web pages”.
For a PUT, I'd return the same view that you'd get if you did a GET immediately after; that would result in a 200 (well, assuming the rendering succeeds of course). For a POST, I'd do a redirect to the resource created (assuming you're doing a creation operation; if not, just return the results); the code for a successful create is a 201, which is really the only HTTP code for a redirect that isn't in the 300 range.
I've never been happy about what a DELETE should return (my code currently produces an HTTP 204 and an empty body in this case).
If a fragment is put on backstack, Android simply destroys its view. The fragment instance itself is not killed. A simple way to start should to to listen to the onViewCreated event, an put you "onResume()" logic there.
boolean fragmentAlreadyLoaded = false;
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
if (savedInstanceState == null && !fragmentAlreadyLoaded) {
fragmentAlreadyLoaded = true;
// Code placed here will be executed once
}
//Code placed here will be executed even when the fragment comes from backstack
}
Try this example.

If you want to change the permissions of an existing file, use chmod (change mode):
$itWorked = chmod ("/yourdir/yourfile", 0777);
If you want all new files to have certain permissions, you need to look into setting your umode
. This is a process setting that applies a default modification to standard modes.
It is a subtractive one. By that, I mean a umode
of 022
will give you a default permission of 755
(777 - 022 = 755
).
But you should think very carefully about both these options. Files created with that mode will be totally unprotected from changes.
One thing that got this working for me is to make sure that github.com
is in ~jenkins/.ssh/known_hosts
.
This is an old post, but this worked for me
<select>_x000D_
<option value="" disabled selected>Please select a name...</option> _x000D_
<option>this</option>_x000D_
<option>that</option>_x000D_
</select>
_x000D_
fill_parent
:
A component is arranged layout for the fill_parent
will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent
will force it to take up the entire screen.
wrap_content
Set up a view of the size of wrap_content
will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content
will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content
roughly equivalent to set a Windows control for True.
For details Please Check out this link : http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html
You probably mean Notification.Builder.setLargeIcon(Bitmap)
, right? :)
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.large_icon);
notBuilder.setLargeIcon(largeIcon);
This is a great method of converting resource images into Android Bitmap
s.
Why it's happening?
due to lock icon
on some folder(not having read/write access) in
"/yourpath/android-studio-SDK"
Sort and sweet solution
-Open Terminal (Ctrl +alt +t)
-copy pest sudo chown -R $USER: $HOME
-wait for a while.....
-now Try again to update your SDK
Happy Coding :)
Yes you can do so and I have created a library for the same.
This allows you to connect up-to four devices to the main server device creating different channels for each client and running interactions on different threads.
To use this library simple add compile com.mdg.androble:library:0.1.2
in dependency section of your build.gradl
e .
Not the best solution, but for those who are facing LazyInitializationException
especially on Serialization
this will help. Here you will check lazily initialized properties and setting null
to those. For that create the below class
public class RepositoryUtil {
public static final boolean isCollectionInitialized(Collection<?> collection) {
if (collection instanceof PersistentCollection)
return ((PersistentCollection) collection).wasInitialized();
else
return true;
}
}
Inside your Entity class which you are having lazily initialized properties add a method like shown below. Add all your lazily loading properties inside this method.
public void checkLazyIntialzation() {
if (!RepositoryUtil.isCollectionInitialized(yourlazyproperty)) {
yourlazyproperty= null;
}
Call this checkLazyIntialzation()
method after on all the places where you are loading data.
YourEntity obj= entityManager.find(YourEntity.class,1L);
obj.checkLazyIntialzation();
Had this problem where the Deployment was in a sub-chart and the values controlling it were in the parent chart's values file. This is what we used to trigger restart:
spec:
template:
metadata:
annotations:
checksum/config: {{ tpl (toYaml .Values) . | sha256sum }}
Obviously this will trigger restart on any value change but it works for our situation. What was originally in the child chart would only work if the config.yaml in the child chart itself changed:
checksum/config: {{ include (print $.Template.BasePath "/config.yaml") . | sha256sum }}
You can apply click
on body
of document and cancel click
processing if the click
event is generated by div with id menu_content
, This will bind event to single element and saving binding of click
with every element except menu_content
$('body').click(function(evt){
if(evt.target.id == "menu_content")
return;
//For descendants of menu_content being clicked, remove this check if you do not want to put constraint on descendants.
if($(evt.target).closest('#menu_content').length)
return;
//Do processing of click event here for every element except with id menu_content
});
text-align: center
will center it horizontally as for vertically put it in a span and give it a css of margin:auto 0;
(you will probably also have to give the span a display: block
property)
There are a thousand and one ways to do it. Here's one using dc
(a reverse-polish desk calculator which supports unlimited precision arithmetic):
dc <<<"$num1 $num2 + p"
But if that's too bash-y for you (or portability matters) you could say
echo $num1 $num2 + p | dc
But maybe you're one of those people who thinks RPN is icky and weird; don't worry! bc
is here for you:
bc <<< "$num1 + $num2"
echo $num1 + $num2 | bc
That said, there are some unrelated improvements you could be making to your script:
#!/bin/bash
num=0
metab=0
for ((i=1; i<=2; i++)); do
for j in output-$i-* ; do # 'for' can glob directly, no need to ls
echo "$j"
# 'grep' can read files, no need to use 'cat'
metab=$(grep EndBuffer "$j" | awk '{sum+=$2} END { print sum/120}')
num=$(( $num + $metab ))
done
echo "$num"
done
As described in Bash FAQ 022, Bash does not natively support floating point numbers. If you need to sum floating point numbers the use of an external tool (like bc
or dc
) is required.
In this case the solution would be
num=$(dc <<<"$num $metab + p")
To add accumulate possibly-floating-point numbers into num
.
You can easily do it by calling this method :
public static Bitmap RotateImage(Image image, float angle)
{
if (image == null)
throw new ArgumentNullException("image");
PointF offset = new PointF((float)image.Width / 2, (float)image.Height / 2);
//create a new empty bitmap to hold rotated image
Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);
//make a graphics object from the empty bitmap
Graphics g = Graphics.FromImage(rotatedBmp);
//Put the rotation point in the center of the image
g.TranslateTransform(offset.X, offset.Y);
//rotate the image
g.RotateTransform(angle);
//move the image back
g.TranslateTransform(-offset.X, -offset.Y);
//draw passed in image onto graphics object
g.DrawImage(image, new PointF(0, 0));
return rotatedBmp;
}
don't forget to add a reference to System.Drawing.dll on your project
Example of this method call :
Image image = new Bitmap("waves.png");
Image newImage = RotateImage(image, 360);
newImage.Save("newWaves.png");
