What worked for me was adding the %JAVA_HOME%\bin
to the Path environment variable with the JAVA_HOME
environment variable pointing to the jdk
folder.
just put chart

You can set a bucket policy as detailed in this blog post:
http://ariejan.net/2010/12/24/public-readable-amazon-s3-bucket-policy/
As per @robbyt's suggestion, create a bucket policy with the following JSON:
{
"Version": "2008-10-17",
"Statement": [{
"Sid": "AllowPublicRead",
"Effect": "Allow",
"Principal": { "AWS": "*" },
"Action": ["s3:GetObject"],
"Resource": ["arn:aws:s3:::bucket/*" ]
}]
}
Important: replace bucket
in the Resource
line with the name of your bucket.
Try removing the position
from header
and add overflow
to container
:
#container {
position:relative;
width:80%;
height:auto;
overflow:auto;
}
#header {
width:80%;
height:50px;
padding:10px;
}
You can use property dangerouslySetInnerHTML
, like this
const Component = React.createClass({_x000D_
iframe: function () {_x000D_
return {_x000D_
__html: this.props.iframe_x000D_
}_x000D_
},_x000D_
_x000D_
render: function() {_x000D_
return (_x000D_
<div>_x000D_
<div dangerouslySetInnerHTML={ this.iframe() } />_x000D_
</div>_x000D_
);_x000D_
}_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
<Component iframe={iframe} />,_x000D_
document.getElementById('container')_x000D_
);
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="container"></div>
_x000D_
also, you can copy all attributes from the string(based on the question, you get iframe as a string from a server) which contains <iframe>
tag and pass it to new <iframe>
tag, like that
/**_x000D_
* getAttrs_x000D_
* returns all attributes from TAG string_x000D_
* @return Object_x000D_
*/_x000D_
const getAttrs = (iframeTag) => {_x000D_
var doc = document.createElement('div');_x000D_
doc.innerHTML = iframeTag;_x000D_
_x000D_
const iframe = doc.getElementsByTagName('iframe')[0];_x000D_
return [].slice_x000D_
.call(iframe.attributes)_x000D_
.reduce((attrs, element) => {_x000D_
attrs[element.name] = element.value;_x000D_
return attrs;_x000D_
}, {});_x000D_
}_x000D_
_x000D_
const Component = React.createClass({_x000D_
render: function() {_x000D_
return (_x000D_
<div>_x000D_
<iframe {...getAttrs(this.props.iframe) } />_x000D_
</div>_x000D_
);_x000D_
}_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
<Component iframe={iframe} />,_x000D_
document.getElementById('container')_x000D_
);
_x000D_

In my case I had one local commit, which wasn't pushed to origin\master
, but commited to my local master
branch. This local commit should be now pushed to another branch.
With Git Extensions you can do something like this:
You could also do that on the GIT command line. Example copied from David Christensen:
I think you'll find
git cherry-pick
+git reset
to be a much quicker workflow:Using your same scenario, with "feature" being the branch with the top-most commit being incorrect, it'd be much easier to do this:
git checkout master
git cherry-pick feature
git checkout feature
git reset --hard HEAD^
Saves quite a bit of work, and is the scenario that
git cherry-pick
was designed to handle.I'll also note that this will work as well if it's not the topmost commit; you just need a commitish for the argument to cherry-pick, via:
git checkout master
git cherry-pick $sha1
git checkout feature
git rebase -i ... # whack the specific commit from the history
In case anyone is still struggling with this, as I was all morning today, I have found a solution that works for me:
Installation instructions:
git clone https://github.com/gstarnberger/uncompyle.git
cd uncompyle/
sudo ./setup.py install
Once the program is installed (note: it will be installed to your system-wide-accessible Python packages, so it should be in your $PATH
), you can recover your Python files like so:
uncompyler.py thank_goodness_this_still_exists.pyc > recovered_file.py
The decompiler adds some noise mostly in the form of comments, however I've found it to be surprisingly clean and faithful to my original code. You will have to remove a little line of text beginning with +++ near the end of the recovered file to be able to run your code.
"FEB-2010" is not a Date, so it would not make a lot of sense to store it in a date column.
You can always extract the string part you need , in your case "MON-YYYY" using the TO_CHAR logic you showed above.
If this is for a DIMENSION table in a Data warehouse environment and you want to include these as separate columns in the Dimension table (as Data attributes), you will need to store the month and Year in two different columns, with appropriate Datatypes...
Example..
Month varchar2(3) --Month code in Alpha..
Year NUMBER -- Year in number
or
Month number(2) --Month Number in Year.
Year NUMBER -- Year in number
app.component.ts
behaviourService.setName("behaviour");
behaviour.service.ts
private name = new BehaviorSubject("");

setName(data) {
this.name.next(data);
}
custom.component.ts
behaviourService.subscribe(response=>{
console.log(response); //output: behaviour
});
From my test (spring 3.0.5), @RequestMapping(value={"", "/"})
- only "/"
works, ""
does not. However I found out this works: @RequestMapping(value={"/", " * "})
, the " * "
matches anything, so it will be the default handler in case no others.
in jquery-3.1.1
$("#id").load(function(){_x000D_
//code goes here});
_x000D_
will not work because load function is no more work

I want to share my experience with this Exception. My JSF 2.2 application worked fine with WildFly 8.0, but one time, when I started server, i got this "Target Unreacheable" exception. Actually, there was no problem with JSF annotations or tags.
Only thing I had to do was cleaning the project. After this operation, my app is working fine again.
I hope this will help someone!
If you do <form action="identification" >
for your html form, data will be passed using 'Get' by default and hence you can catch this using doGet function in your java servlet code. This way data will be passed under the HTML header and hence will be visible in the URL when submitted.
On the other hand if you want to pass data in HTML body, then USE Post: <form action="identification" method="post">
and catch this data in doPost function. This was, data will be passed under the html body and not the html header, and you will not see the data in the URL after submitting the form.
Examples from my html:
<body>
<form action="StartProcessUrl" method="post">
.....
.....
Examples from my java servlet code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
PrintWriter out = response.getWriter();
String surname = request.getParameter("txtSurname");
String firstname = request.getParameter("txtForename");
String rqNo = request.getParameter("txtRQ6");
String nhsNo = request.getParameter("txtNHSNo");
String attachment1 = request.getParameter("base64textarea1");
String attachment2 = request.getParameter("base64textarea2");

UTF stands for stands for Unicode Transformation Format.Basically in today's world there are scripts written in hundreds of other languages, formats not covered by the basic ASCII used earlier. Hence, UTF came into existence.
UTF-8 has character encoding capabilities and its code unit is 8 bits while that for UTF-16 it is 16 bits.
This following works better if you need to scroll to an arbitrary item in the list (rather than always to the bottom):
function scrollIntoView(element, container) {
var containerTop = $(container).scrollTop();
var containerBottom = containerTop + $(container).height();
var elemTop = element.offsetTop;
var elemBottom = elemTop + $(element).height();
if (elemTop < containerTop) {
$(container).scrollTop(elemTop);
} else if (elemBottom > containerBottom) {
$(container).scrollTop(elemBottom - $(container).height());
}
}
What about this solution? Modules and Controllers in Files (at the end of the page) It works with multiple controllers, directives and so on:
app.js
var app = angular.module("myApp", ['deps']);
myCtrl.js
app.controller("myCtrl", function($scope) { ..});
html
<script src="app.js"></script>
<script src="myCtrl.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
Google has also a Best Practice Recommendations for Angular App Structure I really like to group by context. Not all the html in one folder, but for example all files for login (html, css, app.js,controller.js and so on). So if I work on a module, all the directives are easier to find.

You can use the toLowerCase()
method:
public boolean contains( String haystack, String needle ) {
haystack = haystack == null ? "" : haystack;
needle = needle == null ? "" : needle;
// Works, but is not the best.
//return haystack.toLowerCase().indexOf( needle.toLowerCase() ) > -1
return haystack.toLowerCase().contains( needle.toLowerCase() )
}
Then call it using:
if( contains( str1, str2 ) ) {
System.out.println( "Found " + str2 + " within " + str1 + "." );
}
Notice that by creating your own method, you can reuse it. Then, when someone points out that you should use contains
instead of indexOf
, you have only a single line of code to change.
Cloning a specific tag, might return 'detached HEAD' state.
As a workaround, try to clone the repo first, and then checkout a specific tag. For example:
repo_url=https://github.com/owner/project.git
repo_dir=$(basename $repo_url .git)
repo_tag=0.5
git clone --single-branch $repo_url # using --depth 1 can show no tags
git --work-tree=$repo_dir --git-dir=$repo_dir/.git checkout tags/$repo_tag
Note: Since Git 1.8.5, you can use -C <path>
, instead of --work-tree
and --git-dir
.
Some times this trouble may appear if you open this db in another sql server (as example, you launch sql managment studio(SMS) and add this db), and forget stop this server. As result - you app try to connect with user already connected in this db under another server. To fix that, try stop this server by Config. dispatcher sql server.

If you want to get information about your installed python distributions and don't want to use your cmd console or terminal for it, but rather through python code, you can use the following code (tested with python 3.4):
import pip #needed to use the pip functions
for i in pip.get_installed_distributions(local_only=True):
print(i)
The pip.get_installed_distributions(local_only=True)
function-call returns an iterable and because of the for-loop and the print function the elements contained in the iterable are printed out separated by new line characters (\n
).
The result will (depending on your installed distributions) look something like this:
cycler 0.9.0
decorator 4.0.4
ipykernel 4.1.0
ipython 4.0.0
ipython-genutils 0.1.0
ipywidgets 4.0.3
Jinja2 2.8
jsonschema 2.5.1
jupyter 1.0.0
jupyter-client 4.1.1

var fileNames = make([]string, 0, 10)
for i,v:=range filesInfo{
if !v.IsDir() {
fileNames = append(fileNames, v.Name())
}
}
var fileNumber = len(fileNames)
var contents = make([]string, fileNumber, 10)
wg := sync.WaitGroup{}
wg.Add(fileNumber)
for i,_:=range content {
go func(i int){
defer wg.Done()
buf,e := ioutil.Readfile(fmt.Printf("%s/%s", dir, fileName[i]))
defer file.Close()
content[i] = string(buf)

And if you need to do it on items that match a specific condition...
double total = myList.Where(item => item.Name == "Eggs").Sum(item => item.Amount);
I think you are trying to over complicate things. A simple solution is to just style your checkbox by default with the unchecked styles and then add the checked state styles.
input[type="checkbox"] {
// Unchecked Styles
}
input[type="checkbox"]:checked {
// Checked Styles
}
I apologize for bringing up an old thread but felt like it could have used a better answer.
EDIT (3/3/2016):
W3C Specs state that :not(:checked)
as their example for selecting the unchecked state. However, this is explicitly the unchecked state and will only apply those styles to the unchecked state. This is useful for adding styling that is only needed on the unchecked state and would need removed from the checked state if used on the input[type="checkbox"]
selector. See example below for clarification.
input[type="checkbox"] {
/* Base Styles aka unchecked */
font-weight: 300; // Will be overwritten by :checked
font-size: 16px; // Base styling
}
input[type="checkbox"]:not(:checked) {
/* Explicit Unchecked Styles */
border: 1px solid #FF0000; // Only apply border to unchecked state
}
input[type="checkbox"]:checked {
/* Checked Styles */
font-weight: 900; // Use a bold font when checked
}
Without using :not(:checked)
in the example above the :checked
selector would have needed to use a border: none;
to achieve the same affect.
Use the input[type="checkbox"]
for base styling to reduce duplication.
Use the input[type="checkbox"]:not(:checked)
for explicit unchecked styles that you do not want to apply to the checked state.
The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.
The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.
The ?
operand makes match non-greedy. E.g. .*
is greedy while .*?
isn't. So you can use something like <img.*?>
to match the whole tag. Or <img[^>]*>
.
But remember that the whole set of HTML can't be actually parsed with regular expressions.
First i tried with this sample code:
$(document).ready(function(){
$('#upload-file').click();
});
It didn't work for me. Then after, tried with this
$(document).ready(function(){
$('#upload-file')[0].click();
});
No change. At last, tried with this
$(document).ready(function(){
$('#upload-file')[0].click(function(){
});
});
Solved my problem. Helpful for anyone.
The CSV format sounds easy enough for StringTokenizer but it can become more complicated. Here in Germany a semicolon is used as a delimiter and cells containing delimiters need to be escaped. You're not going to handle that easily with StringTokenizer.
I would go for http://sourceforge.net/projects/javacsv
Form values in HTTP POSTs are sent in the request body, in the same format as the querystring.

I was having this same issue and I resolved it in the following way...
I have the NVIDIA "Tegra Android Development Pack" installed and it seems to also have a version of mysysgit.exe with it. TortoiseGit automatically found that installation location (instead of the standard git installation) and auto-populated it in the settings menu.
To correct this, go to: "Settings -> General" and there is a field for the path to mysysgit.exe. Make sure this is pointing to the correct installation.
Usage with the final router
With the introduction of the new router it became easier to guard the routes. You must define a guard, which acts as a service, and add it to the route.
import { Injectable } from '@angular/core';
import { CanActivate } from '@angular/router';
import { UserService } from '../../auth';
@Injectable()
export class LoggedInGuard implements CanActivate {
constructor(user: UserService) {
this._user = user;
}
canActivate() {
return this._user.isLoggedIn();
}
}
Now pass the LoggedInGuard
to the route and also add it to the providers
array of the module.
import { LoginComponent } from './components/login.component';
import { HomeComponent } from './components/home.component';
import { LoggedInGuard } from './guards/loggedin.guard';
const routes = [
{ path: '', component: HomeComponent, canActivate: [LoggedInGuard] },
{ path: 'login', component: LoginComponent },
];
The module declaration:
@NgModule({
declarations: [AppComponent, HomeComponent, LoginComponent]
imports: [HttpModule, BrowserModule, RouterModule.forRoot(routes)],
providers: [UserService, LoggedInGuard],
bootstrap: [AppComponent]
})
class AppModule {}
Detailed blog post about how it works with the final release: https://medium.com/@blacksonic86/angular-2-authentication-revisited-611bf7373bf9
Usage with the deprecated router
A more robust solution is to extend the RouterOutlet
and when activating a route check if the user is logged in. This way you don't have to copy and paste your directive to every component. Plus redirecting based on a subcomponent can be misleading.
@Directive({
selector: 'router-outlet'
})
export class LoggedInRouterOutlet extends RouterOutlet {
publicRoutes: Array;
private parentRouter: Router;
private userService: UserService;
constructor(
_elementRef: ElementRef, _loader: DynamicComponentLoader,
_parentRouter: Router, @Attribute('name') nameAttr: string,
userService: UserService
) {
super(_elementRef, _loader, _parentRouter, nameAttr);
this.parentRouter = _parentRouter;
this.userService = userService;
this.publicRoutes = [
'', 'login', 'signup'
];
}
activate(instruction: ComponentInstruction) {
if (this._canActivate(instruction.urlPath)) {
return super.activate(instruction);
}
this.parentRouter.navigate(['Login']);
}
_canActivate(url) {
return this.publicRoutes.indexOf(url) !== -1 || this.userService.isLoggedIn()
}
}
The UserService
stands for the place where your business logic resides whether the user is logged in or not. You can add it easily with DI in the constructor.
When the user navigates to a new url on your website, the activate method is called with the current Instruction. From it you can grab the url and decide whether it is allowed or not. If not just redirect to the login page.
One last thing remain to make it work, is to pass it to our main component instead of the built in one.
@Component({
selector: 'app',
directives: [LoggedInRouterOutlet],
template: template
})
@RouteConfig(...)
export class AppComponent { }
This solution can not be used with the @CanActive
lifecycle decorator, because if the function passed to it resolves false, the activate method of the RouterOutlet
won't be called.
Also wrote a detailed blog post about it: https://medium.com/@blacksonic86/authentication-in-angular-2-958052c64492
Running your code shows an image for me, after adjusting the path. Can you verify that your image path is correct, try absolute path for instance?
From the DOCS
Formats a number as text. Group sizing and separator and other locale-specific configurations are based on the active locale.
SYNTAX:
number_expression | number[:digitInfo[:locale]]
where expression
is a number:
digitInfo
is a string which has a following format:
{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
The non-recursive version of the function is not too hard - here it is for integers:
long powi(long x, unsigned n)
{
long p = x;
long r = 1;
while (n > 0)
{
if (n % 2 == 1)
r *= p;
p *= p;
n /= 2;
}
return(r);
}
(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)
$resource was meant to retrieve data from an endpoint, manipulate it and send it back. You've got some of that in there, but you're not really leveraging it for what it was made to do.
It's fine to have custom methods on your resource, but you don't want to miss out on the cool features it comes with OOTB.
EDIT: I don't think I explained this well enough originally, but $resource
does some funky stuff with returns. Todo.get()
and Todo.query()
both return the resource object, and pass it into the callback for when the get completes. It does some fancy stuff with promises behind the scenes that mean you can call $save()
before the get()
callback actually fires, and it will wait. It's probably best just to deal with your resource inside of a promise then()
or the callback method.
var Todo = $resource('/api/1/todo/:id');
//create a todo
var todo1 = new Todo();
todo1.foo = 'bar';
todo1.something = 123;
todo1.$save();
//get and update a todo
var todo2 = Todo.get({id: 123});
todo2.foo += '!';
todo2.$save();
//which is basically the same as...
Todo.get({id: 123}, function(todo) {
todo.foo += '!';
todo.$save();
});
//get a list of todos
Todo.query(function(todos) {
//do something with todos
angular.forEach(todos, function(todo) {
todo.foo += ' something';
todo.$save();
});
});
//delete a todo
Todo.$delete({id: 123});
Likewise, in the case of what you posted in the OP, you could get a resource object and then call any of your custom functions on it (theoretically):
var something = src.GetTodo({id: 123});
something.foo = 'hi there';
something.UpdateTodo();
I'd experiment with the OOTB implementation before I went and invented my own however. And if you find you're not using any of the default features of $resource
, you should probably just be using $http
on it's own.
As of Angular 1.2, resources support promises. But they didn't change the rest of the behavior.
To leverage promises with $resource
, you need to use the $promise
property on the returned value.
var Todo = $resource('/api/1/todo/:id');
Todo.get({id: 123}).$promise.then(function(todo) {
// success
$scope.todos = todos;
}, function(errResponse) {
// fail
});
Todo.query().$promise.then(function(todos) {
// success
$scope.todos = todos;
}, function(errResponse) {
// fail
});
Just keep in mind that the $promise
property is a property on the same values it was returning above. So you can get weird:
var todo = Todo.get({id: 123}, function() {
$scope.todo = todo;
});
Todo.get({id: 123}, function(todo) {
$scope.todo = todo;
});
Todo.get({id: 123}).$promise.then(function(todo) {
$scope.todo = todo;
});
var todo = Todo.get({id: 123});
todo.$promise.then(function() {
$scope.todo = todo;
});
While it looks like your setup is correct, there are a few things to check:
env
- specifically PATH
.command -v java
tells you what?java
executable in $JAVA_HOME\bin
and does it have the execute bit set? If not chmod a+x java
it.I trust you have source
'd your .profile
after adding/changing the JAVA_HOME
and PATH
?
Also, you can help yourself in future maintenance of your JDK installation by writing this instead:
export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=$JAVA_HOME/bin:$PATH
Then you only need to update one env variable when you setup the JDK installation.
Finally, you may need to run hash -r
to clear the Bash program cache. Other shells may need a similar command.

Set the margin for body at 0 and that will fix it.
body {
margin: 0;
}
$("a[href*=ABC]").addClass('selected');
Your form should look like this :
<form action="myprocessingscript.php" method="POST">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
and the PHP
<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
$data = $_POST['field1'] . '-' . $_POST['field2'] . "\r\n";
$ret = file_put_contents('/tmp/mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
I wrote to /tmp/mydata.txt
because this way I know exactly where it is. using data.txt
writes to that file in the current working directory which I know nothing of in your example.
file_put_contents
opens, writes and closes files for you. Don't mess with it.

For Ubuntu 18.04 or PHP 7.2 users you can do:
apt-get install php7.2-curl
You can check your PHP version by running php -v
to verify your PHP version and get the right curl version.
You should use @RequestParam
on those resources with method = RequestMethod.GET
In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType
).
Typically, multipart/form-data is used to upload files.
IMHO you need to read many links , resources to make an idea about the difference between Runtime vs Compile time because it is a very complex subject . I have list below some of this pictures/links that I am recommend .
Apart from what it is said above I want to add that sometimes a picture worth 1000 words :
CLR_diag compile time and then runtime2
from Wiki
https://en.wikipedia.org/wiki/Run_time https://en.wikipedia.org/wiki/Run_time_(program_lifecycle_phase)
Run time, run-time, or runtime may refer to:
Computing
Run time (program lifecycle phase), the period during which a computer program is executing
Runtime library, a program library designed to implement functions built into a programming language
Runtime system, software designed to support the execution of computer programs
Software execution, the process of performing instructions one by one during the run time phase
List of compilers https://en.wikipedia.org/wiki/List_of_compilers
;
3.2 the difference between this 3 things : compile vs build vs runtime
https://www.quora.com/What-is-the-difference-between-build-run-and-compile Fernando Padoan, A developer that's just a bit curious for language design Answered Feb 23 I’m going backwards in relation to other answers:
running is getting some binary executable (or a script, for interpreted languages) to be, well… executed as a new process on the computer; compiling is the process of parsing a program written in some high level language (higher if compared to machine code), checking it’s syntax, semantics, linking libraries, maybe doing some optimization, then creating a binary executable program as an output. This executable may be in the form of machine code, or some kind of byte code — that is, instructions targeting some kind of virtual machine; building usually involves checking and providing dependencies, inspecting code, compiling the code into binary, running automated tests and packaging the resulting binary[ies] and other assets (images, configuration files, libraries, etc.) into some specific format of deployable file. Note that most processes are optional and some depend on the targeted platform you are building for. As an example, packaging a Java application for Tomcat will output a .war file. Building a Win32 executable out of C++ code could just output the .exe program, or could also package it inside a .msi installer.
No. You have to make your own like this:
boolean tryParseInt(String value) {
try {
Integer.parseInt(value);
return true;
} catch (NumberFormatException e) {
return false;
}
}
...and you can use it like this:
if (tryParseInt(input)) {
Integer.parseInt(input); // We now know that it's safe to parse
}
EDIT (Based on the comment by @Erk)
Something like follows should be better
public int tryParse(String value, int defaultVal) {
try {
return Integer.parseInt(value);
} catch (NumberFormatException e) {
return defaultVal;
}
}
When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.
public int tryParse(String value) {
return tryParse(value, 0)
}
As @Agam said,
You need this statement in your driver file:
from AthleteList import AtheleteList
As above told, if you want no one can change the functionality of the method then you can declare it as final.
Example: Application server file path for download/upload, splitting string based on offset, such methods you can declare it Final so that these method functions will not be altered. And if you want such final methods in a separate class, then define that class as Final class. So Final class will have all final methods, where as Final method can be declared and defined in non-final class.
Try it using CONCAT
CONCAT('site.com/path/','%', CAST(t1.id AS CHAR(25)), '%','/more')
You can use as many joins as you want, however, the more you use the more it will impact performance
You were almost done without any changes besides how you spyOn
.
When you use the spy, you have two options: spyOn
the App.prototype
, or component component.instance()
.
const spy = jest.spyOn(Class.prototype, "method")
The order of attaching the spy on the class prototype and rendering (shallow rendering) your instance is important.
const spy = jest.spyOn(App.prototype, "myClickFn");
const instance = shallow(<App />);
The App.prototype
bit on the first line there are what you needed to make things work. A JavaScript class
doesn't have any of its methods until you instantiate it with new MyClass()
, or you dip into the MyClass.prototype
. For your particular question, you just needed to spy on the App.prototype
method myClickFn
.
jest.spyOn(component.instance(), "method")
const component = shallow(<App />);
const spy = jest.spyOn(component.instance(), "myClickFn");
This method requires a shallow/render/mount
instance of a React.Component
to be available. Essentially spyOn
is just looking for something to hijack and shove into a jest.fn()
. It could be:
A plain object
:
const obj = {a: x => (true)};
const spy = jest.spyOn(obj, "a");
A class
:
class Foo {
bar() {}
}
const nope = jest.spyOn(Foo, "bar");
// THROWS ERROR. Foo has no "bar" method.
// Only an instance of Foo has "bar".
const fooSpy = jest.spyOn(Foo.prototype, "bar");
// Any call to "bar" will trigger this spy; prototype or instance
const fooInstance = new Foo();
const fooInstanceSpy = jest.spyOn(fooInstance, "bar");
// Any call fooInstance makes to "bar" will trigger this spy.
Or a React.Component instance
:
const component = shallow(<App />);
/*
component.instance()
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(component.instance(), "myClickFn");
Or a React.Component.prototype
:
/*
App.prototype
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(App.prototype, "myClickFn");
// Any call to "myClickFn" from any instance of App will trigger this spy.
I've used and seen both methods. When I have a beforeEach()
or beforeAll()
block, I might go with the first approach. If I just need a quick spy, I'll use the second. Just mind the order of attaching the spy.
EDIT:
If you want to check the side effects of your myClickFn
you can just invoke it in a separate test.
const app = shallow(<App />);
app.instance().myClickFn()
/*
Now assert your function does what it is supposed to do...
eg.
expect(app.state("foo")).toEqual("bar");
*/
EDIT:
Here is an example of using a functional component. Keep in mind that any methods scoped within your functional component are not available for spying. You would be spying on function props passed into your functional component and testing the invocation of those. This example explores the use of jest.fn()
as opposed to jest.spyOn
, both of which share the mock function API. While it does not answer the original question, it still provides insight on other techniques that could suit cases indirectly related to the question.
function Component({ myClickFn, items }) {
const handleClick = (id) => {
return () => myClickFn(id);
};
return (<>
{items.map(({id, name}) => (
<div key={id} onClick={handleClick(id)}>{name}</div>
))}
</>);
}
const props = { myClickFn: jest.fn(), items: [/*...{id, name}*/] };
const component = render(<Component {...props} />);
// Do stuff to fire a click event
expect(props.myClickFn).toHaveBeenCalledWith(/*whatever*/);
Regarding the list as a tree, the deep_copy in python can be most compactly written as
def deep_copy(x):
if not isinstance(x, list): return x
else: return map(deep_copy, x)
Or you can set up crontab to run a script. Inside that script you can set an environment variable like this:
export PGPASSWORD="$put_here_the_password"
This way if you have multiple commands that would require password you can put them all in the script. If the password changes you only have to change it in one place (the script).
And I agree with Joshua, using pg_dump -Fc
generates the most flexible export format and is already compressed. For more info see: pg_dump documentation
E.g.
# dump the database in custom-format archive
pg_dump -Fc mydb > db.dump
# restore the database
pg_restore -d newdb db.dump
In order to have Click Listener
, DoubleClick Listener
, OnLongPress Listener
, Swipe Left
, Swipe Right
, Swipe Up
, Swipe Down
on Single View
you need to setOnTouchListener
. i.e,
view.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {
@Override
public void onClick() {
super.onClick();
// your on click here
}
@Override
public void onDoubleClick() {
super.onDoubleClick();
// your on onDoubleClick here
}
@Override
public void onLongClick() {
super.onLongClick();
// your on onLongClick here
}
@Override
public void onSwipeUp() {
super.onSwipeUp();
// your swipe up here
}
@Override
public void onSwipeDown() {
super.onSwipeDown();
// your swipe down here.
}
@Override
public void onSwipeLeft() {
super.onSwipeLeft();
// your swipe left here.
}
@Override
public void onSwipeRight() {
super.onSwipeRight();
// your swipe right here.
}
});
}
For this you need OnSwipeTouchListener
class that implements OnTouchListener
.
public class OnSwipeTouchListener implements View.OnTouchListener {
private GestureDetector gestureDetector;
public OnSwipeTouchListener(Context c) {
gestureDetector = new GestureDetector(c, new GestureListener());
}
public boolean onTouch(final View view, final MotionEvent motionEvent) {
return gestureDetector.onTouchEvent(motionEvent);
}
private final class GestureListener extends GestureDetector.SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
@Override
public boolean onDown(MotionEvent e) {
return true;
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
onClick();
return super.onSingleTapUp(e);
}
@Override
public boolean onDoubleTap(MotionEvent e) {
onDoubleClick();
return super.onDoubleTap(e);
}
@Override
public void onLongPress(MotionEvent e) {
onLongClick();
super.onLongPress(e);
}
// Determines the fling velocity and then fires the appropriate swipe event accordingly
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
}
} else {
if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
onSwipeDown();
} else {
onSwipeUp();
}
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
return result;
}
}
public void onSwipeRight() {
}
public void onSwipeLeft() {
}
public void onSwipeUp() {
}
public void onSwipeDown() {
}
public void onClick() {
}
public void onDoubleClick() {
}
public void onLongClick() {
}
}

The current answers are outdated. You should be able to use #error version
(at the top of any C# file in the project, or nearly anywhere in the code). The compiler treats this in a special way and reports a compiler error, CS8304, indicating the language version, and also the compiler version. The message of CS8304 is something that looks like the following:
error CS8304: Compiler version: '3.7.0-3.20312.3 (ec484126)'. Language version: 6.
Ignoring the refactoring issues, you need to understand functions and return values. You don't need a global at all. Ever. You can do this:
def rps():
# Code to determine if player wins
if player_wins:
return True
return False
Then, just assign a value to the variable outside this function like so:
player_wins = rps()
It will be assigned the return value (either True or False) of the function you just called.
After the comments, I decided to add that idiomatically, this would be better expressed thus:
def rps():
# Code to determine if player wins, assigning a boolean value (True or False)
# to the variable player_wins.
return player_wins
pw = rps()
This assigns the boolean value of player_wins
(inside the function) to the pw
variable outside the function.
I see two options:
1) Implement your own IViewEngine and set the ViewEngine property of the Controller you are using to your ImageViewEngine in your desired "image" method.
2) Use a view :-). Just change the content type etc.
The answer is a simple PowerShell
one-liner:
Get-WmiObject Win32_NetworkConnection | ft "RemoteName","LocalName" -A
If you only want to pull the UNC
for one particular drive, add a where statement:
Get-WmiObject Win32_NetworkConnection | where -Property 'LocalName' -eq 'Z:' | ft "RemoteName","LocalName" -A
You can take advantage of fschange. It’s a Linux filesystem change notification. The source code is downloadable from the above link, you can compile it yourself. fschange
can be used to keep track of file changes by reading data from a proc file (/proc/fschange). When data is written to a file, fschange reports the exact interval that has been modified instead of just saying that the file has been changed.
If you are looking for the more advanced solution, I would suggest checking Resilio Connect.
It is cross-platform, provides extended options for use and monitoring. Since it’s BitTorrent-based, it is faster than any other existing sync tool. It was written on their behalf.
Create "topN" query on "clientip" and then histogram with count on "clientip" and set "topN" query as source. Then you will see count of different ips per time.
Instead of entering "EST" for the timezone you can enter "EST5EDT" as such. As you noted, just "EDT" does not work. This will account for the daylight savings time issue. The code line looks like this:
Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("EST5EDT"));
As @bmleite already mentioned in the comments, you probably forgot to load angular.js.
If I create a fiddle with angular directives in it, but don't include angular.js I get the exact same error in the Chrome console: Uncaught ReferenceError: angular is not defined
You can sort it std::sort(v, v + 2000)
Your syntax is incorrect. The var
keyword in your for
loop must be followed by a variable name, in this case its propName
var propValue;
for(var propName in nyc) {
propValue = nyc[propName]
console.log(propName,propValue);
}
I suggest you have a look here for some basics:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in
there is a function called isNaN
it return true if it's (Not-a-number) , so u can check for a number this way
if(!isNaN(miscCharge))
{
//do some thing if it's a number
}else{
//do some thing if it's NOT a number
}
hope it works
There is actually one easy option (for recent browsers and Node.js) missing in the existing answers:
console.log('Item: %o', o);
I would prefer this as JSON.stringify()
has certain limitations (e.g. with circular structures).
NUnit is probably the most supported by the 3rd party tools. It's also been around longer than the other three.
I personally don't care much about unit test frameworks, mocking libraries are IMHO much more important (and lock you in much more). Just pick one and stick with it.
Since maven-surefire-plugin does not run Suite class first but treats suite and test classes same, so we can configure plugin as below to enable only suite classes and disable all the tests. Suite will run all the tests.

You could use a negative look-ahead assertion:
^(?!tbd_).+
Or a negative look-behind assertion:
(^.{1,3}$|^.{4}(?<!tbd_).*)
Or just plain old character sets and alternations:
^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*
In case you add a new login, make sure that under server properties ( rightclick -> properties)/security, authentication mode is set to both sqlserver and windows not only windows.
I like TcpCatcher because it is very simple to use and has a modern interface. It is provided as a jar file, you just download it and run it (no installation process). Also, it comes with a very useful "on the fly" packets modification features (debug mode).
Utilizing/Copying Darin Dimitrov's great response, this is how to access a custom attribute on a property and not a class:
The decorated property [of class Foo
]:
[MyCustomAttribute(SomeProperty = "This is a custom property")]
public string MyProperty { get; set; }
Fetching it:
PropertyInfo propertyInfo = typeof(Foo).GetProperty(propertyToCheck);
object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
if (attribute.Length > 0)
{
MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
string propertyValue = myAttribute.SomeProperty;
}
You can throw this in a loop and use reflection to access this custom attribute on each property of class Foo
, as well:
foreach (PropertyInfo propertyInfo in Foo.GetType().GetProperties())
{
string propertyName = propertyInfo.Name;
object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
// Just in case you have a property without this annotation
if (attribute.Length > 0)
{
MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
string propertyValue = myAttribute.SomeProperty;
// TODO: whatever you need with this propertyValue
}
}
Major thanks to you, Darin!!
Here's my simple solution for the two basic cases differing on whether you want to load the graph from file or build it during runtime.
This answer holds for Tensorflow 0.12+ (including 1.0).
graph = ... # build the graph
saver = tf.train.Saver() # create the saver after the graph
with ... as sess: # your session object
saver.save(sess, 'my-model')
graph = ... # build the graph
saver = tf.train.Saver() # create the saver after the graph
with ... as sess: # your session object
saver.restore(sess, tf.train.latest_checkpoint('./'))
# now you can use the graph, continue training or whatever
When using this technique, make sure all your layers/variables have explicitly set unique names. Otherwise Tensorflow will make the names unique itself and they'll be thus different from the names stored in the file. It's not a problem in the previous technique, because the names are "mangled" the same way in both loading and saving.
graph = ... # build the graph
for op in [ ... ]: # operators you want to use after restoring the model
tf.add_to_collection('ops_to_restore', op)
saver = tf.train.Saver() # create the saver after the graph
with ... as sess: # your session object
saver.save(sess, 'my-model')
with ... as sess: # your session object
saver = tf.train.import_meta_graph('my-model.meta')
saver.restore(sess, tf.train.latest_checkpoint('./'))
ops = tf.get_collection('ops_to_restore') # here are your operators in the same order in which you saved them to the collection
In this day and age of mouse driven computers and tablets with touch screens etc, it is often forgotten to cater for input via keyboard only. A button should support a focus rectangle (the dotted rectangle when the button has focus) or another shape matching the button shape.
To add a focus rectangle to the button, use this XAML (from this site). Focus rectangle style:
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Border>
<Rectangle Margin="2" StrokeThickness="1" Stroke="#60000000" StrokeDashArray="1 2" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Applying the style to the button:
<Style TargetType="Button">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}" />
...
you can easily access elements by index , by use System.Linq
Here is the sample
First add using in your class file
using System.Linq;
Then
yourDictionaryData.ElementAt(i).Key
yourDictionaryData.ElementAt(i).Value
Hope this helps.

Example
For a pure javascript example, without using jQuery, check out this answer.
Without JavaScript, it's not possible to open two pages by clicking one link unless both pages are framed on the one page that opens from clicking the link. With JS it's trivial:
<p><a href="#" onclick="window.open('http://google.com');
window.open('http://yahoo.com');">Click to open Google and Yahoo</a></p>
Do note that this will be blocked by popup blockers built into web browsers but you are usually notified of this.
It is possible to do with CSS only by selecting active and focus pseudo element of the button.
button:active{
background:olive;
}
button:focus{
background:olive;
}
See codepen: http://codepen.io/fennefoss/pen/Bpqdqx
You could also write a simple jQuery click function which changes the background color.
HTML:
<button class="js-click">Click me!</button>
CSS:
button {
background: none;
}
JavaScript:
$( ".js-click" ).click(function() {
$( ".js-click" ).css('background', 'green');
});
Check out this codepen: http://codepen.io/fennefoss/pen/pRxrVG
source myscript.sh
is also feasible.
Description for linux command source
:
source is a Unix command that evaluates the file following the command,
as a list of commands, executed in the current context
You can't do this with CSS alone. Using jQuery you can do
HTML
<label id="lab">Checkbox</label>
<input id="check" type="checkbox" />
CSS
.highlight{
background:yellow;
}
jQuery
$('#check').click(function(){
$('#lab').toggleClass('highlight')
})
This will work in all browsers

So this regex matches "drupal-6.14/" that is not followed by "sites" that is not followed by "/all" or "/default".
Confusing? Using different words, we can say it matches "drupal-6.14/" that is not followed by "sites" unless that is further followed by "/all" or "/default"
You don't need to convert the original entry - you can use TEXT function in the concatenation formula, e.g. with date in A1 use a formula like this

You can change the "dd-mm-yyyy" part as required

You need to add a pseudo-hostname to the CALLBACK_URL 'app://' doesn't make sense as a URL and cannot be parsed.
Here is the way I look at COALESCE...and hopefully it makes sense...
In a simplistic form….
Coalesce(FieldName, 'Empty')
So this translates to…If "FieldName" is NULL, populate the field value with the word "EMPTY".
Now for mutliple values...
Coalesce(FieldName1, FieldName2, Value2, Value3)
If the value in Fieldname1 is null, fill it with the value in Fieldname2, if FieldName2 is NULL, fill it with Value2, etc.
This piece of test code for the AdventureWorks2012 sample database works perfectly & gives a good visual explanation of how COALESCE works:
SELECT Name, Class, Color, ProductNumber,
COALESCE(Class, Color, ProductNumber) AS FirstNotNull
FROM Production.Product
It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test
.
If you use ((
…))
, you are testing arithmetic equality with ==
as in C:
$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1
(Note: 0
means true
in the Unix sense and a failed test results in a non-zero number.)
Using -eq
inside of double parentheses is a syntax error.
If you are using [
…]
(or single brackets) or [[
…]]
(or double brackets), or test
you can use one of -eq
, -ne
, -lt
, -le
, -gt
, or -ge
as an arithmetic comparison.
$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0
The ==
inside of single or double brackets (or the test
command) is one of the string comparison operators:
$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1
As a string operator, =
is equivalent to ==
. Also, note the whitespace around =
or ==
: it’s required.
While you can do [[ 1 == 1 ]]
or [[ $(( 1+1 )) == 2 ]]
it is testing the string equality — not the arithmetic equality.
So -eq
produces the result probably expected that the integer value of 1+1
is equal to 2
even though the right-hand side is a string and has a trailing space:
$ [[ $(( 1+1 )) -eq "2 " ]]; echo $?
0
While a string comparison of the same picks up the trailing space and therefore the string comparison fails:
$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1
And a mistaken string comparison can produce a completely wrong answer. 10
is lexicographically less than 2
, so a string comparison returns true
or 0
. So many are bitten by this bug:
$ [[ 10 < 2 ]]; echo $?
0
The correct test for 10
being arithmetically less than 2
is this:
$ [[ 10 -lt 2 ]]; echo $?
1
In comments, there is a question about the technical reason why using the integer -eq
on strings returns true for strings that are not the same:
$ [[ "yes" -eq "no" ]]; echo $?
0
The reason is that Bash is untyped. The -eq
causes the strings to be interpreted as integers if possible including base conversion:
$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0
And 0
if Bash thinks it is just a string:
$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1
So [[ "yes" -eq "no" ]]
is equivalent to [[ 0 -eq 0 ]]
Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]]
and ((...))
or ==
.
You can bind key press event with your input box and returning false
if characters are more than 160 will solve the problem jsfiddle.
JavaScript:
$('textarea').keypress(function(){
if(this.value.length > 160){
return false;
}
$("#remainingC").html("Remaining characters : " + (160 - this.value.length));
});?
HTML
<textarea></textarea>?
<span id='remainingC'></span>
You actually need to pass a function inside the window.setTimeout()
which you want to execute after 5000 milliseconds, like this:
$(document).ready(function () {
// Handler for .ready() called.
window.setTimeout(function () {
location.href = "https://www.google.co.in";
}, 5000);
});
For More info: .setTimeout()
For anyone wondering how to do it in cordova hybrid app:
go to index.js ->
inside the function onDeviceReady() write :
subscribe();
(It's important to write it at the top of the function!)
then, in the same file (index.js) find :
function subscribe(){
FirebasePlugin.subscribe("write_here_your_topic", function(){
},function(error){
logError("Failed to subscribe to topic", error);
});
}
and write your own topic here ->
"write_here_your_topic"
In case of lazy loading, you just need to import MatDialogModule in lazy loaded module. Then this module will be able to render entry component with its own imported MatDialogModule:
@NgModule({
imports:[
MatDialogModule
],
declarations: [
AppComponent,
LoginComponent,
DashboardComponent,
HomeComponent,
DialogResultExampleDialog
],
entryComponents: [DialogResultExampleDialog]
I do the following:
This essentially turns the file into a bash executable. When you double-click it, it should run. This works in Unix-based systems.
This simplifies it a bit and it behaves as you want it.
FileWriter f = new FileWriter("../playlist/"+existingPlaylist.getText()+".txt");
try {
f.write(source);
...
} catch(...) {
} finally {
//close it here
}
Date Between Query
SELECT *
FROM emp
WHERE HIREDATE between to_date (to_char(sysdate, 'yyyy') ||'/09/01', 'yyyy/mm/dd')
AND to_date (to_char(sysdate, 'yyyy') + 1|| '/08/31', 'yyyy/mm/dd');
I had a similar problem going through a tutorial.
# git mv README README.markdown
fatal: bad source, source=README, destination=README.markdown
I included the filetype in the source file:
# git mv README.rdoc README.markdown
and it worked perfectly. Don't forget to commit the changes with i.e.:
# git commit -a -m "Improved the README"
Sometimes it is simple little things like that, that piss us off. LOL
Use preventDefault()
to stop the event of submit button and in ajax call success submit the form using submit()
:
$('#btnSave').click(function (e) {
e.preventDefault(); // <------------------ stop default behaviour of button
var element = this;
$.ajax({
url: "/Home/SaveDetailedInfo",
type: "POST",
data: JSON.stringify({ 'Options': someData}),
dataType: "json",
traditional: true,
contentType: "application/json; charset=utf-8",
success: function (data) {
if (data.status == "Success") {
alert("Done");
$(element).closest("form").submit(); //<------------ submit form
} else {
alert("Error occurs on the Database level!");
}
},
error: function () {
alert("An error has occured!!!");
}
});
});
In Bash 4 (as well as ZSH 4.3.11):

I've recently found even more interesting way to create any ValueNode
or ContainerNode
(Jackson v2.3).
ObjectNode node = JsonNodeFactory.instance.objectNode();
json
is a built-in module, you don't need to install it with pip
.
-qscale:v
to control qualityUse -qscale:v
(or the alias -q:v
) as an output option.
-qmin 1
output option (because the default is -qmin 2
).ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg
See the image muxer documentation for more options involving image outputs.
ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg
Internet Explorer (IE8 and lower) doesn't support addEventListener(...)
. It has its own event model using the attachEvent
method. You could use some code like this:
var element = document.getElementById('container');
if (document.addEventListener){
element .addEventListener('copy', beforeCopy, false);
} else if (el.attachEvent){
element .attachEvent('oncopy', beforeCopy);
}
Though I recommend avoiding writing your own event handling wrapper and instead use a JavaScript framework (such as jQuery, Dojo, MooTools, YUI, Prototype, etc) and avoid having to create the fix for this on your own.
By the way, the third argument in the W3C model of events has to do with the difference between bubbling and capturing events. In almost every situation you'll want to handle events as they bubble, not when they're captured. It is useful when using event delegation on things like "focus" events for text boxes, which don't bubble.
Server.MapPath specifies the relative or virtual path to map to a physical directory.
Server.MapPath(".")
1 returns the current physical directory of the file (e.g. aspx) being executedServer.MapPath("..")
returns the parent directoryServer.MapPath("~")
returns the physical path to the root of the applicationServer.MapPath("/")
returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)An example:
Let's say you pointed a web site application (http://www.example.com/
) to
C:\Inetpub\wwwroot
and installed your shop application (sub web as virtual directory in IIS, marked as application) in
D:\WebApps\shop
For example, if you call Server.MapPath()
in following request:
http://www.example.com/shop/products/GetProduct.aspx?id=2342
then:
Server.MapPath(".")
1 returns D:\WebApps\shop\products
Server.MapPath("..")
returns D:\WebApps\shop
Server.MapPath("~")
returns D:\WebApps\shop
Server.MapPath("/")
returns C:\Inetpub\wwwroot
Server.MapPath("/shop")
returns D:\WebApps\shop
If Path starts with either a forward slash (/
) or backward slash (\
), the MapPath()
returns a path as if Path was a full, virtual path.
If Path doesn't start with a slash, the MapPath()
returns a path relative to the directory of the request being processed.
Note: in C#, @
is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.
Footnotes
Server.MapPath(null)
and Server.MapPath("")
will produce this effect too.I managed to do it myself. No need for any plugins. Check out my gist:
// Replace #fromA with your button/control and #toB with the target to which
// You wanna scroll to.
//
$("#fromA").click(function() {
$("html, body").animate({ scrollTop: $("#toB").offset().top }, 1500);
});
This can be resolved in another way:
app.get("/", function(req, res){
res.send(`${process.env.PWD}/index.html`)
});
process.env.PWD
will prepend the working directory when the process was started.
document.getElementById('myDiv').style.height = 500;
This is the very basic JS code required to adjust the height of your object dynamically. I just did this very thing where I had some auto height property, but when I add some content via XMLHttpRequest
I needed to resize my parent div and this offsetheight property did the trick in IE6/7 and FF3
Reflection.
using System.Reflection;
Vendor vendor = new Vendor();
object tag = vendor.Tag;
Type tagt = tag.GetType();
FieldInfo field = tagt.GetField("test");
string value = field.GetValue(tag);
Use the power wisely. Don't forget error checking. :)
This question belongs more on Server Fault but FWIW I'd say running Apache in front of Node.js is not a good approach in most cases.
Apache's ProxyPass is awesome for lots of things (like exposing Tomcat based services as part of a site) and if your Node.js app is just doing a specific, small role or is an internal tool that's only likely to have a limited number of users then it might be easier just to use it so you can get it working and move on, but that doesn't sound like the case here.
If you want to take advantage of the performance and scale you'll get from using Node.js - and especially if you want to use something that involves maintaining a persistent connection like web sockets - you are better off running both Apache and your Node.js on other ports (e.g. Apache on localhost:8080, Node.js on localhost:3000) and then running something like nginx, Varnish or HA proxy in front - and routing traffic that way.
With something like varnish or nginx you can route traffic based on path and/or host. They both use much less system resources and is much more scalable that using Apache to do the same thing.

I created multiple threads in Python, I printed the thread objects, and I printed the id using the ident
variable. I see all the ids are same:
<Thread(Thread-1, stopped 140500807628544)>
<Thread(Thread-2, started 140500807628544)>
<Thread(Thread-3, started 140500807628544)>
Just add to @Bert's solution to make it more clear:
const routes = [
{ path: '/foo', component: Foo },
{ path: '/bar', component: Bar }
]
const router = new VueRouter({
routes,
linkExactActiveClass: "active" // active class for *exact* links.
})
As one can see, this line should be removed:
linkActiveClass: "active", // active class for non-exact links.
this way, ONLY the current link is hi-lighted. This should apply to most of the cases.

typeperf
gives me issues when it randomly doesn't work on some computers (Error: No valid counters.
) or if the account has insufficient rights. Otherwise, here is a way to extract just the value from its output. It still needs rounding though:
@for /f "delims=, tokens=2" %p in ('typeperf "\Processor(_Total)\% Processor Time" -sc 3 ^| find ":"') do @echo %~p%
Powershell has two cmdlets to get the percent utilization for all CPUs: Get-Counter
(preferred) or Get-WmiObject
:
Powershell "Get-Counter '\Processor(*)\% Processor Time' | Select -Expand Countersamples | Select InstanceName, CookedValue"
Or,
Powershell "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime"
To get the overall CPU load with formatted output exactly like the question:
Powershell "[string][int](Get-Counter '\Processor(*)\% Processor Time').Countersamples[0].CookedValue + '%'"
Or,
Powershell "gwmi Win32_PerfFormattedData_PerfOS_Processor | Select -First 1 | %{'{0}%' -f $_.PercentProcessorTime}"
You can use DateTime
import org.joda.time.DateTime
Option 1 : with yyyyMMddHHmmss
DateTime.now().toString("yyyyMMddHHmmss")
Will give 20190205214430
Option 2 : yyyy-dd-M--HH-mm-ss
DateTime.now().toString("yyyy-dd-M--HH-mm-ss")
will give 2019-05-2--21-43-32

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

fig = plt.figure(order, figsize=(9, 6))
ax = fig.add_subplot(111)
bp = ax.boxplot(data_plot)
fig.savefig(file_name, bbox_inches='tight')
plt.close()

I would've saved time if I found Resteasy Jackson Provider sooner.
Just add the Resteasy Jackson Provider JAR. No entity wrappers. No XML annotations. No custom message body writers.
It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult
is generic, however you can determine the exact issue catching HttpRequestException
and then inspecting InnerException
: if it's a WebException
then you can check the WebException.Status
property, for example WebExceptionStatus.NameResolutionFailure
should indicate a DNS resolution problem.
It may happen, there isn't much you can do.
What I'd suggest to always wrap that (network related) code in a loop with a try
/catch
block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:
private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;
public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
using (var client = new HttpClient()) {
for (int i=1; i <= NumberOfRetries; ++i) {
try {
return await client.GetAsync(url);
}
catch (Exception e) when (i < NumberOfRetries) {
await Task.Delay(DelayOnRetry);
}
}
}
}
The SELECT * FROM table1, table2, ...
syntax is ok for a couple of tables, but it becomes exponentially (not necessarily a mathematically accurate statement) harder and harder to read as the number of tables increases.
The JOIN syntax is harder to write (at the beginning), but it makes it explicit what criteria affects which tables. This makes it much harder to make a mistake.
Also, if all the joins are INNER, then both versions are equivalent. However, the moment you have an OUTER join anywhere in the statement, things get much more complicated and it's virtually guarantee that what you write won't be querying what you think you wrote.
If you need to escape JSON inside JSON string, use org.json.JSONObject.quote("your json string that needs to be escaped") seem to work well
I suspect the error is caused by this:
foreach (KeyValuePair<int, int> kvp in rankings)
rankings is a dictionary, which is IEnumerable. By using it in a foreach loop, you're specifying that you want each KeyValuePair from the dictionary in a deferred manner. That is, the next KeyValuePair is not returned until your loop iterates again.
But you're modifying the dictionary inside your loop:
rankings[kvp.Key] = rankings[kvp.Key] + 4;
which isn't allowed...so you get the exception.
You could simply do this
foreach (KeyValuePair<int, int> kvp in rankings.ToArray())
If you're using a Unix like OS (Linux, OSX, etc) then you can use a combination of find
and egrep
to search for require statements containing your package name:
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'name-of-package' {} \;
If you search for the entire require('name-of-package')
statement, remember to use the correct type of quotation marks:
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'require("name-of-package")' {} \;
or
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni "require('name-of-package')" {} \;
The downside is that it's not fully automatic, i.e. it doesn't extract package names from package.json
and check them. You need to do this for each package yourself. Since package.json
is just JSON this could be remedied by writing a small script that uses child_process.exec
to run this command for each dependency. And make it a module. And add it to the NPM repo...
You could use multiple background: linear-gradient(); calls, but try this:
If you want the images to be completely fused together where it doesn't look like the elements load separately due to separate HTTP requests then use this technique. Here we're loading two things on the same element that load simultaneously...
Just make sure you convert your pre-rendered 32-bit transparent png image/texture to base64 string first and use it within the background-image css call (in place of INSERTIMAGEBLOBHERE in this example).
I used this technique to fuse a wafer looking texture and other image data that's serialized with a standard rgba transparency / linear gradient css rule. Works better than layering multiple art and wasting HTTP requests which is bad for mobile. Everything is loaded client side with no file operation required, but does increase document byte size.
div.imgDiv {
background: linear-gradient(to right bottom, white, rgba(255,255,255,0.95), rgba(255,255,255,0.95), rgba(255,255,255,0.9), rgba(255,255,255,0.9), rgba(255,255,255,0.85), rgba(255,255,255,0.8) );
background-image: url("data:image/png;base64,INSERTIMAGEBLOBHERE");
}
Installing this package allows you to use gem

If you're allowed to use predefined Java classes, you could do something like:
private static ArrayList<ArrayList<String>> biDemArrList = new ArrayList<ArrayList<String>>();
Then you can add new elements, something like:
ArrayList<String> temp = new ArrayList<String>(); // added ()
temp.add("Hello world.");
biDemArrList.add(temp);
Hope you can understand what I mean and what's going on. Also, you'll need to import java.util.ArrayList; for this, if you're making use of the Java class.
The last update was a while ago, so here is what worked for me on Ubuntu:
sudo apt-get update
sudo apt-get install nginx-extras
Then add the following two lines to the http
section of nginx.conf
, which is usually located at /etc/nginx/nginx.conf:
sudo nano /etc/nginx/nginx.conf
server_tokens off; # removed pound sign
more_set_headers 'Server: Eff_You_Script_Kiddies!';
Also, don't forget to restart nginx with sudo service nginx restart
.

The purpose of .iteritems()
was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()
though it's been proved to be efficient than .items()
If you want to include a code that supports both the PY version 2 and 3,
try:
iteritems
except NameError:
iteritems = items
This can help if you deploy your project in some other system and you aren't sure about the PY version.
We have similar situation right now and as of this answer, I am using laravel 5.6 release.
I will not use your example in the question but mine, because it's related though.
I have route like this:
Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');
Then in your controller method, make sure you include
use Illuminate\Http\Request;
and this should be above your controller, most likely a default, if generated using php artisan
, now to get variable from the url it should look like this:
public function someMethod(Request $request)
{
$foo = $request->input("start");
$bar = $request->input("limit");
// some codes here
}
Regardless of the HTTP verb, the input() method may be used to retrieve user input.

Hope this help.
In my case the width of the contentView was greater than the width of UIScrollView and that was the reason for unwanted horizontal scrolling. I solved it by setting the width of contentView equal to width of UIScrollView.

DateTime
Decimal
Double
Int16
Int32
Int64
SByte

I just found Scandinavian Keyboard as a fine solution to this problem. It do also have English and German keyboard, but neither Dutch nor Spanish - but I guess they could be added. And I guess there is other alternatives out there.
Escape the quotes with backslashes:
printf("She said \"time flies like an arrow, but fruit flies like a banana\".");
There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.
Use <iomanip>
's std::hex
. If you print, just send it to std::cout
, if not, then use std::stringstream
std::stringstream stream;
stream << std::hex << your_int;
std::string result( stream.str() );
You can prepend the first <<
with << "0x"
or whatever you like if you wish.
Other manips of interest are std::oct
(octal) and std::dec
(back to decimal).
One problem you may encounter is the fact that this produces the exact amount of digits needed to represent it. You may use setfill
and setw
this to circumvent the problem:
stream << std::setfill ('0') << std::setw(sizeof(your_type)*2)
<< std::hex << your_int;
So finally, I'd suggest such a function:
template< typename T >
std::string int_to_hex( T i )
{
std::stringstream stream;
stream << "0x"
<< std::setfill ('0') << std::setw(sizeof(T)*2)
<< std::hex << i;
return stream.str();
}
Best way to rounding off a floating value by "n" decimal places, is as following with in O(1) time:-
We have to round off the value by 3 places i.e. n=3.So,
float a=47.8732355;
printf("%.3f",a);
This is a supplement answer related to the OP:
An easy and reliable solution to add Javadocs comments in Eclipse:
To use this tool, right-click on class and click on JAutodoc.
I think the answers are below
List<string> aa = (from char c in source
select c.ToString() ).ToList();
List<string> aa2 = (from char c1 in source
from char c2 in source
select string.Concat(c1, ".", c2)).ToList();
Just set the header width to be 100vw to make it full screen width and set the header height to be 100vh to make it full screen height
To return a different view, you can specify the name
of the view you want to return and model
as follows:
return View("ViewName", yourModel);
if the view is in different folder under Views folder then use below absolute path:
return View("~/Views/FolderName/ViewName.aspx");
I can't really comment on specific libraries, but in principle there's little reason for such operations to be slower in Java. Hotspot generally does the kinds of things you'd expect a compiler to do: it compiles basic math operations on Java variables to corresponding machine instructions (it uses SSE instructions, but only one per operation); accesses to elements of an array are compiled to use "raw" MOV instructions as you'd expect; it makes decisions on how to allocate variables to registers when it can; it re-orders instructions to take advantage of processor architecture... A possible exception is that as I mentioned, Hotspot will only perform one operation per SSE instruction; in principle you could have a fantastically optimised matrix library that performed multiple operations per instruction, although I don't know if, say, your particular FORTRAN library does so or if such a library even exists. If it does, there's currently no way for Java (or at least, Hotspot) to compete with that (though you could of course write your own native library with those optimisations to call from Java).
So what does all this mean? Well:
A hindrance to matrix operations is often data locality issues that arise when you need to traverse both row by row and column by column, e.g. in matrix multiplication, since you have to store the data in an order that optimises one or the other. But if you hand-write the code, you can sometimes combine operations to optimise data locality (e.g. if you're multiplying a matrix by its transformation, you can turn a column traversal into a row traversal if you write a dedicated function instead of combining two library functions). As usual in life, a library will give you non-optimal performance in exchange for faster development; you need to decide just how important performance is to you.
Make sure that "android-support-v4.jar" is unchecked in Order and Export tab under Java Build Path
Follow the steps:
Unlike in the case of Angular, in React.js you need to update the state manually. You can do something like this:
<input
className="form-control"
type="text" value={this.state.name}
id={'todoName' + this.props.id}
onChange={e => this.onTodoChange(e.target.value)}
/>
And then in the function:
onTodoChange(value){
this.setState({
name: value
});
}
Also, you can set the initial state in the constructor of the component:
constructor (props) {
super(props);
this.state = {
updatable: false,
name: props.name,
status: props.status
};
}
To fix your specific error you need to run that command as sudo, ie:
sudo gem install rails --pre
I have a complicated Web App and I couldn't figure out exactly why this error was being thrown. It was causing the JavaScript to abort when thrown.
In select2.js I changed:
if (typeof(opts.query) !== "function") {
throw "query function not defined for Select2 " + opts.element.attr("id");
}
to:
if (typeof(opts.query) !== "function") {
console.error("query function not defined for Select2 " + opts.element.attr("id"));
}
Now everything seems to work properly but it is still logging in error in case I want to try and figure out what exactly in my code is causing the error. But for now this is a good enough fix for me.
Using CocoaPods with a Gemfile
With a Gemfile setup, you run bundle install
to install, or bundle update
to update within your Gemfile's constraints. From here on in however, you will need to remember to run bundle exec
before any terminal commands that have come in via bundler. Given that CocoaPods is included in the above this means any time you would write pod XX YY
you need to do bundle exec pod XX YY
.
Doing it without bundle exec
will bypass your Gemfile's specific versioning and will use the latest version of the library within RubyGems. This could potentially be the exact same version, but it can often not. If you are including CocoaPods plugins then they may also not be run.
This means you can be sure that foundational tooling for projects are versioned just like your personal libraries.
Delete the Intermediate folder after then run the project is working fine actually that APK builds to another system. Go to app/build/intermediates.
Please store your JSON file with the .js extension and make sure that your JSON should be in same directory.
If your existing code is already relying on from datetime import datetime
, you can also simply also import date
from datetime import datetime, timedelta, date
print isinstance(datetime.today().date(), date)
You can connect with MSSMS to LocalDB. Type only in SERVER NAME: (localdb)\v11.0 and leave it by Windows Authentication and it connects to your LocalDB server and shows you the databases in it.
Extending Bhesh Gurung's answer for assigning values, you can add explicit method to set value
public ExitCode setValue( int value){
// A(104), B(203);
switch(value){
case 104: return ExitCode.A;
case 203: return ExitCode.B;
default:
return ExitCode.Unknown //Keep an default or error enum handy
}
}
From calling application
int i = 104;
ExitCode serverExitCode = ExitCode.setValue(i);
//You've valid enum from now

It looks like you are using entity framework. My solution was to switch all datetime columns to datetime2, and use datetime2 for any new columns, in other words make EF use datetime2 by default. Add this to the OnModelCreating method on your context:
modelBuilder.Properties<DateTime>().Configure(c => c.HasColumnType("datetime2"));
That will get all the DateTime and DateTime? properties on all the entities in your model.

The problem is how to do layout with floats (figures and tables, an similar objects) and footnotes. In particular, it is hard to pick a place for a float with certainty that making room for the associated footnotes won't cause trouble. So the standard tabular
and figure
environments don't even try.
What can you do:
\footnotesize
for the size). You also have to manage the symbols or number yourself with \footnotemark
. Simple, but not very attractive, and the footnote does not appear at the bottom of the page.tabularx
, longtable
, threeparttable[x]
(kudos to Joseph) or ctable
which support this behavior.[h!]
(or [H]
with the float package) to control where the float will appear, and \footnotetext
on the same page to put the footnote where you want it. Again, use \footnotemark
to install the symbol. Fragile and requires hand-tooling every instance.footnotes
package provides the savenote
environment, which can be used to do this.\begin{figure} \begin{minipage}{\textwidth} ... \caption[Caption for LOF]% {Real caption\footnote{blah}} \end{minipage} \end{figure}

If the database is installed on a different machine it has probably correct version of pg_dump installed. This means that you can execute pg_dump command remotely with SSH:
ssh username@dbserver pg_dump books > books.out
You can also use public key authentication for passwordless execution. Steps to achieve that:
Look at the r.status_code
attribute:
if r.status_code == 404:
# A 404 was issued.
Demo:
>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404
If you want requests
to raise an exception for error codes (4xx or 5xx), call r.raise_for_status()
:
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "requests/models.py", line 664, in raise_for_status
raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.
You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:
if r:
# successful response
If you want to be more explicit, use if r.ok:
.
Installing framework 4.0 redistributable is also enough to create application pool. You can download it from here.
Have a same problem. My solution is after you handle with parsing arguments using argparse or other way, remove arguments from sys.argv
sys.argv = sys.argv[:1]
If you need you can filter unittest arguments from main.parseArgs()
IP addresses are part of the Network layer in the "seven-layer stack". The Network layer can do whatever it wants to do with the IP address. That's what happens with a proxy server, NAT, relay, or whatever.
The Application layer should not depend on the IP address in any way. In particular, an IP Address is not meant to be an identifier of anything other than the idenfitier of one end of a network connection. As soon as a connection is closed, you should expect the IP address (of the same user) to change.
Short answer, no, there's no way to 'trigger' the default functionality of the html5 bubble inline before submission of the form, you can checkValidity()
on certain inputs, but again doesn't work as you would want. Short of preventing the default if you still want to submit the form once validation is complete, you can still process this style by doing the following:
Note, on forms you don't want the validation css styles to be applied, you can simply add the novalidate
attribute to the form.
HTML:
<form name="login" id="loginForm" method="POST">
<input type="email" name="username" placeholder="Email">
<input type="password" name="password" placeholder="Password">
<input type="submit" value="LOG IN" class="hero left clearBoth">
</form>
If you're not using SCSS, I would highly recommend looking into it, it's much more manageable, easy to write and less convoluted. Note: In the fiddle example, i do have the exact css that this will compile. I've also included a bubble style example.
SCSS:
form:not([novalidate]) {
input, textarea {
&:required {background: transparent url('/../../images/icons/red_asterisk.png') no-repeat 98% center;}
&:required:valid {background: transparent url('/../../images/icons/valid.png') no-repeat 98% center; @include box-shadow(0 0 5px #5cd053);border-color: #28921f;}
&:not(:focus):valid {box-shadow: none;border: 1px solid $g4;}
&:focus:invalid {background: transparent url('/../../images/icons/invalid.png') no-repeat 98% center; @include box-shadow(0 0 5px #d45252); border-color: #b03535}
}
}
span.formHintBubble {position:absolute; background:$g7; margin-top:50px;@include borderRadius(10px); padding:5px 40px 5px 10px; color:white; @include opacity(0.9); @include box-shadow(1px 1px 6px 1px rgba(0,0,0,0.2));
&:after {
@include triangle(30px, $g7, up); content: " "; margin-bottom:27px; left:25px;
}
.cross {background:black; border:1px solid $g3; @include borderRadius(10px); width:15px; height:15px; color:#fff; display:block; line-height:15px; position:absolute; right:5px; top:50%; margin-top:-7.5px; padding:0; text-align:center; font-size:10px; cursor:pointer;}
}
JAVASCRIPT:
Here, we can do some funky stuff to use the default messages and inherit them inside your own 'bubble' or error message box.
var form = $('form');
var item = form.find(':invalid').first();
var node = item.get(0);
var pos = item.position();
var message = node.validationMessage || 'Invalid value.';
var bubble = $('<span/>').html('<span class="formHintBubble" style="left: ' + pos.left + 'px; top:' + pos.top + 'px;">' + message + '<div class="cross">X</div></span>').contents();
bubble.insertAfter(item);

Enjoy and I hope I help others with HTML5 form validation as it's awesome, and it needs to get out there!

I faced similar issue, with RelativeLayout as the root element for each row in the recyclerview.
To solve the issue, find the xml file that holds each row and make sure that the root element's height is wrap_content
NOT match_parent
.
In package.json you will find an eslintConfig

"extends": [
"eslint:recommended"

The only thing I don't like is that you have to define/register all child classes.
Dot notation does not work with some keywords (like new
and class
) in internet explorer 8.
I had this code:
//app.users is a hash
app.users.new = {
// some code
}
And this triggers the dreaded "expected indentifier" (at least on IE8 on windows xp, I havn't tried other environments). The simple fix for that is to switch to bracket notation:
app.users['new'] = {
// some code
}
Starting from C++23 you can use std::string::contains
#include <string>
const auto haystack = std::string("haystack with needles");
const auto needle = std::string("needle");
if (haystack.contains(needle))
{
// found!
}

I have developed this functionality from one Blog. There are 2 ways you can send SMS.
This is the code of 1st method.
Main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<Button
android:id="@+id/btnSendSMS"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Send SMS"
android:layout_centerInParent="true"
android:onClick="sendSMS">
</Button>
</RelativeLayout>
Activity
public class SendSMSActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void sendSMS(View v)
{
String number = "12346556"; // The number on which you want to send SMS
startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", number, null)));
}
/* or
public void sendSMS(View v)
{
Uri uri = Uri.parse("smsto:12346556");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
it.putExtra("sms_body", "Here you can set the SMS text to be sent");
startActivity(it);
} */
}
NOTE:- In this method, you don’t require SEND_SMS permission inside the AndroidManifest.xml file.
For 2nd method refer to this BLOG. You will find a good explanation from here.
Hope this will help you...
