In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:
.ball {
animation: bounce 1s infinite alternate;
-webkit-animation: bounce 1s infinite alternate;
}
@keyframes bounce {
from {
margin-top: 0;
}
to {
margin-top: -15px;
}
}
For every client you need to start separate thread. Example:
public class ThreadedEchoServer {
static final int PORT = 1978;
public static void main(String args[]) {
ServerSocket serverSocket = null;
Socket socket = null;
try {
serverSocket = new ServerSocket(PORT);
} catch (IOException e) {
e.printStackTrace();
}
while (true) {
try {
socket = serverSocket.accept();
} catch (IOException e) {
System.out.println("I/O error: " + e);
}
// new thread for a client
new EchoThread(socket).start();
}
}
}
and
public class EchoThread extends Thread {
protected Socket socket;
public EchoThread(Socket clientSocket) {
this.socket = clientSocket;
}
public void run() {
InputStream inp = null;
BufferedReader brinp = null;
DataOutputStream out = null;
try {
inp = socket.getInputStream();
brinp = new BufferedReader(new InputStreamReader(inp));
out = new DataOutputStream(socket.getOutputStream());
} catch (IOException e) {
return;
}
String line;
while (true) {
try {
line = brinp.readLine();
if ((line == null) || line.equalsIgnoreCase("QUIT")) {
socket.close();
return;
} else {
out.writeBytes(line + "\n\r");
out.flush();
}
} catch (IOException e) {
e.printStackTrace();
return;
}
}
}
}
You can also go with more advanced solution, that uses NIO selectors, so you will not have to create thread for every client, but that's a bit more complicated.
I found this blog post which explains the problem very well, and defines a few different solutions:
(dead link removed)
I've settled for the idea that the best way to do it is to completely omit the XML declaration when in memory. It actually is UTF-16 at that point anyway, but the XML declaration doesn't seem meaningful until it has been written to a file with a particular encoding; and even then the declaration is not required. It doesn't seem to break deserialization, at least.
As @Jon Hanna mentions, this can be done with an XmlWriter created like this:
XmlWriter writer = XmlWriter.Create (output, new XmlWriterSettings() { OmitXmlDeclaration = true });
If you don't have access to a subfolder inside the directory tree, Directory.GetFiles stops and throws the exception resulting in a null value in the receiving string[].
Here, see this answer https://stackoverflow.com/a/38959208/6310707
It manages the exception inside the loop and keep on working untill the entire folder is traversed.
You can use the ljust
method on strings.
>>> name = 'John'
>>> name.ljust(15)
'John '
Note that if the name is longer than 15 characters, ljust
won't truncate it. If you want to end up with exactly 15 characters, you can slice the resulting string:
>>> name.ljust(15)[:15]
You could also try setting style
inline without using a variable, like so:
style={{"height" : "100%"}}
or,
for multiple attributes: style={{"height" : "100%", "width" : "50%"}}
If the function floatval does not work you can try to make this :
$string = "2968789218";
$float = $string * 1.0;
echo $float;
But for me all the previous answer worked ( try it in http://writecodeonline.com/php/ ) Maybe the problem is on your server ?
I suggest to use "return false" instead of useing some javascript in the href-tag:
<form id="">
...
</form>
<a href="#" onclick="document.getElementById('myform').submit(); return false;">send form</a>
Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.
public ActionResult ClientIdSearch(int cid)
{
var action = String.Format("Details/{0}", cid);
return RedirectToAction(action, "Accounts");
}
I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.
You Can't write JSON file while in assets. as already described assets are read-only. But you can copy assets (json file/anything else in assets ) to local storage of mobile and then edit(write/read) from local storage. More storage options like shared Preference(for small data) and sqlite database(for large data) are available.
You may find the following function useful:
function typeOf(obj) {
return {}.toString.call(obj).split(' ')[1].slice(0, -1).toLowerCase();
}
Or in ES7 (comment if further improvements)
function typeOf(obj) {
const { toString } = Object.prototype;
const stringified = obj::toString();
const type = stringified.split(' ')[1].slice(0, -1);
return type.toLowerCase();
}
Results:
typeOf(); //undefined
typeOf(null); //null
typeOf(NaN); //number
typeOf(5); //number
typeOf({}); //object
typeOf([]); //array
typeOf(''); //string
typeOf(function () {}); //function
typeOf(/a/) //regexp
typeOf(new Date()) //date
typeOf(new WeakMap()) //weakmap
typeOf(new Map()) //map

If you can't solve the problem for the rectangle try dividing the problem in to easier problems. Divide the rectangle into 2 triangles an check if the point is inside any of them like they explain in here
Essentially, you cycle through the edges on every two pairs of lines from a point. Then using cross product to check if the point is between the two lines using the cross product. If it's verified for all 3 points, then the point is inside the triangle. The good thing about this method is that it does not create any float-point errors which happens if you check for angles.
this some kind of late but anyway and it is also somewhat tricky
dim arrr
arr= array ("Apples", "Oranges", "Bananas")
dim temp_var
temp_var = join (arr , "||") ' some character which will not occur is regular strings
if len(temp_var) > 0 then
temp_var = temp_var&"||Watermelons"
end if
arr = split(temp_var , "||") ' here you got new elemet in array '
for each x in arr
response.write(x & "<br />")
next'
review and tell me if this can work or initially you save all data in string and later split for array
string = "removeTHISplease";
result = string.replace('THIS','');
I think replace do the same thing like a some own function. For me this works.
Unfortunately disown

This will work with iPad on Safari on iOS 7.1.x from my testing, I'm not sure about iOS 6 though. However, it will not work on Firefox. There is a jQuery plugin which aims to be cross browser compliant called jScrollPane.
Also, there is a duplicate post here on Stack Overflow which has some other details.
I found a solution by myself after doing some research:
Now everything works fine.
Maybe there's a more simple answer, try to add any background color you like to the code, like background-color: #fff;
#alpha {
background-color: #fff;
opacity: 0.8;
filter: alpha(opacity=80);
}
Not sure if this is helpful but here's an example of Handlebars template with dynamic parameters passed to an inline RadioButtons partial and the client(browser) rendering the radio buttons in the container.
For my use it's rendered with Handlebars on the server and lets the client finish it up. With it a forms tool can provide inline data within Handlebars without helpers.
Note : This example requires jQuery
{{#*inline "RadioButtons"}}
{{name}} Buttons<hr>
<div id="key-{{{name}}}"></div>
<script>
{{{buttons}}}.map((o)=>{
$("#key-{{name}}").append($(''
+'<button class="checkbox">'
+'<input name="{{{name}}}" type="radio" value="'+o.value+'" />'+o.text
+'</button>'
));
});
// A little test script
$("#key-{{{name}}} .checkbox").on("click",function(){
alert($("input",this).val());
});
</script>
{{/inline}}
{{>RadioButtons name="Radio" buttons='[
{value:1,text:"One"},
{value:2,text:"Two"},
{value:3,text:"Three"}]'
}}
Code bellow allows to play mp3-files and in-memory wave-files too
player.FileName = "123.mp3";
player.Play();
from http://alvas.net/alvas.audio,samples.aspx#sample6 or
Player pl = new Player();
byte[] arr = File.ReadAllBytes(@"in.wav");
pl.Play(arr);
In a nutshell what it does is refer to the id
of the input, that's all:
<label for="the-id-of-the-input">Input here:</label>
<input type="text" name="the-name-of-input" id="the-id-of-the-input">
public void OnClick(View.v)
Button b1 = (Button) findViewById(R.id.playButton);
b1.setVisiblity(View.INVISIBLE);
I had the exact same problem. Here is the solution that worked for me: simply put your properties file path in the cmd line this way :
-Dlog4j.configuration=<FILE_PATH> (ex: log4j.properties)
Hope this will help you
Public strHostName As String
Public strIPAddress As String
strHostName = System.Net.Dns.GetHostName()
strIPAddress = System.Net.Dns.GetHostEntry(strHostName).AddressList(0).ToString()
MessageBox.Show("Host Name: " & strHostName & "; IP Address: " & strIPAddress)
You can think of the static methods and non-static methods of a class as being different interfaces. When called, static methods resolve to the singleton static class object, and non-static methods resolve to the instance of the class you deal with. So, if you use static and non-static methods in an interface, you'd effectively be declaring two interfaces when really we want interfaces to be used to access one cohesive thing.
In PL/SQL you can't use operators such as '=' or '<>' to test for NULL
because all comparisons to NULL
return NULL
. To compare something against NULL
you need to use the special operators IS NULL
or IS NOT NULL
which are there for precisely this purpose. Thus, instead of writing
IF var = NULL THEN...
you should write
IF VAR IS NULL THEN...
In the case you've given you also have the option of using the NVL
built-in function. NVL
takes two arguments, the first being a variable and the second being a value (constant or computed). NVL
looks at its first argument and, if it finds that the first argument is NULL
, returns the second argument. If the first argument to NVL
is not NULL
, the first argument is returned. So you could rewrite
IF var IS NULL THEN
var := 5;
END IF;
as
var := NVL(var, 5);
I hope this helps.
And because it's nearly ten years since I wrote this answer, let's celebrate by expanding it just a bit.
The COALESCE
function is the ANSI equivalent of Oracle's NVL
. It differs from NVL
in a couple of IMO good ways:
It takes any number of arguments, and returns the first one which is not NULL. If all the arguments passed to COALESCE
are NULL, it returns NULL.
In contrast to NVL
, COALESCE
only evaluates arguments if it must, while NVL
evaluates both of its arguments and then determines if the first one is NULL, etc. So COALESCE
can be more efficient, because it doesn't spend time evaluating things which won't be used (and which can potentially cause unwanted side effects), but it also means that COALESCE
is not a 100% straightforward drop-in replacement for NVL
.
See ?order
. You just need the last index (or first, in decreasing order), so this should do the trick:
order(matrix[,2],decreasing=T)[1]
One more simple way you can try out which will not add duplicate Value before adding object in array:-
//Assume mutableArray is allocated and initialize and contains some value
if (![yourMutableArray containsObject:someValue])
{
[yourMutableArray addObject:someValue];
}
In my case a has to add my classes, when building the SessionFactory
, with addAnnotationClass
Configuration configuration.configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration
.addAnnotatedClass(MyEntity1.class)
.addAnnotatedClass(MyEntity2.class)
.buildSessionFactory(builder.build());
if just everything could be this simple...
#logo {background:url(../global_images/csg-4b15a4b83d966.png) no-repeat top left;background-position:0 -825px;float:left;height:48px;position:relative;width:112px}
#logo a {padding-top:48px; display:block;}
<div id="logo"><a href="../../index.html"></a></div>
just think a little outside the box ;-)
I wound up writing my own command-line tool to take care of this. It's similar to cut
, except it knows what to do with quoted fields, etc. This tool, paired with @Jimothy's answer, allows me to get a headerless CSV from a remote MySQL server I have no filesystem access to onto my local machine with this command:
$ mysql -N -e "select people, places from things" | csvm -i '\t' -o ','
Bill,"Raleigh, NC"
Another one-liner that is not too complicated:
private int countNumberOfPages(int numberOfObjects, int pageSize) {
return numberOfObjects / pageSize + (numberOfObjects % pageSize == 0 ? 0 : 1);
}
Could use long instead of int; just change the parameter types and return type.
I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).
SWFUpload is a good start : http://www.swfupload.org/documentation
jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.
Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html
If you need stricter replacement matching, PostgreSQL's regexp_replace
function can match using POSIX regular expression patterns. It has the syntax regexp_replace(source, pattern, replacement [, flags ]).
I will use flags i
and g
for case-insensitive and global matching, respectively. I will also use \m
and \M
to match the beginning and the end of a word, respectively.
There are usually quite a few gotchas when performing regex replacment. Let's see how easy it is to replace a cat with a dog.
SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog');
--> Cat bobdog cat cats catfish
SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'i');
--> dog bobcat cat cats catfish
SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'g');
--> Cat bobdog dog dogs dogfish
SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'gi');
--> dog bobdog dog dogs dogfish
SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat', 'dog', 'gi');
--> dog bobcat dog dogs dogfish
SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat\M', 'dog', 'gi');
--> dog bobdog dog cats catfish
SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat\M', 'dog', 'gi');
--> dog bobcat dog cats catfish
SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat(s?)\M', 'dog\1', 'gi');
--> dog bobcat dog dogs catfish
Even after all of that, there is at least one unresolved condition. For example, sentences that begin with "Cat" will be replaced with lower-case "dog" which break sentence capitalization.
Check out the current PostgreSQL pattern matching docs for all the details.
Given my examples, maybe the safest option would be:
UPDATE table SET field = regexp_replace(field, '\mcat\M', 'dog', 'gi');
You could use the highlight effect in jQuery UI to achieve the same, I guess.

Did you include "bootstrap-theme.css" files on your code?
In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).
It will re-declare your style code, and then it will be effected on your code.
So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.
in express there may be application-scoped JSON formatters.
after looking at express\lib\response.js, I'm using this routine:
function writeJsonPToRes(app, req, res, obj) {
var replacer = app.get('json replacer');
var spaces = app.get('json spaces');
res.set('Content-Type', 'application/json');
var partOfResponse = JSON.stringify(obj, replacer, spaces)
.replace(/\u2028/g, '\\u2028')
.replace(/\u2029/g, '\\u2029');
var callback = req.query[app.get('jsonp callback name')];
if (callback) {
if (Array.isArray(callback)) callback = callback[0];
res.set('Content-Type', 'text/javascript');
var cb = callback.replace(/[^\[\]\w$.]/g, '');
partOfResponse = 'typeof ' + cb + ' === \'function\' && ' + cb + '(' + partOfResponse + ');\n';
}
res.write(partOfResponse);
}

If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform
property:
.myclass {
text-transform: lowercase;
}
See https://developer.mozilla.org/en/CSS/text-transform for more info.
However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.
Look carefully at your includes - perhaps you have a blank line after a closing ?> ?
This will cause some literal whitespace to be sent as output, preventing you from making subsequent header calls.
Note that it is legal to leave the close ?> off the include file, which is a useful idiom for avoiding this problem.
(EDIT: looking at your header, you need to avoid doing any HTML output if you want to output headers, or use output buffering to capture it).
Finally, as the PHP manual page for header points out, you should really use full URLs to redirect:
Note: HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:
I am achieving it something like this.
>>> import requests
>>> url = "http://news.bbc.co.uk/2/hi/health/2284783.stm"
>>> res = requests.get(url)
>>> text = res.text
Note that if you have a generic interface IMyInterface<T>
then this will always return false
:
typeof(IMyInterface<>).IsAssignableFrom(typeof(MyType)) /* ALWAYS FALSE */
This doesn't work either:
typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface<>)) /* ALWAYS FALSE */
However, if MyType
implements IMyInterface<MyType>
this works and returns true
:
typeof(IMyInterface<MyType>).IsAssignableFrom(typeof(MyType))
However, you likely will not know the type parameter T
at runtime. A somewhat hacky solution is:
typeof(MyType).GetInterfaces()
.Any(x=>x.Name == typeof(IMyInterface<>).Name)
Jeff's solution is a bit less hacky:
typeof(MyType).GetInterfaces()
.Any(i => i.IsGenericType
&& i.GetGenericTypeDefinition() == typeof(IMyInterface<>));
Here's a extension method on Type
that works for any case:
public static class TypeExtensions
{
public static bool IsImplementing(this Type type, Type someInterface)
{
return type.GetInterfaces()
.Any(i => i == someInterface
|| i.IsGenericType
&& i.GetGenericTypeDefinition() == someInterface);
}
}
(Note that the above uses linq, which is probably slower than a loop.)
You can then do:
typeof(MyType).IsImplementing(IMyInterface<>)
It seem like your Resort
method doesn't declare a compareTo
method. This method typically belongs to the Comparable
interface. Make sure your class implements it.
Additionally, the compareTo
method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String
argument, but rather a Resort
.
Alternatively, you can compare the names of the resorts. For example
if (resortList[mid].getResortName().compareTo(resortName)>0)
You could also use Command Prompt with move
: move x.extension .extension
Try this simple query. It works perfectly.

I recommend Derek Bruening's bar graph generator Perl script. Available at http://www.burningcutlery.com/derek/bargraph/
"use strict";
Basically it enables the strict mode.
Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.
As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.
So, there will be no major difference how "use strict";
is interpreted by the Chrome browser and Node.js.
Please read what is strict mode in JavaScript.
For more information:
ECMAScript 6 Code & strict mode. Following is brief from the specification:
10.2.1 Strict Mode Code
An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:
- Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
- Module code is always strict mode code.
- All parts of a ClassDeclaration or a ClassExpression are strict mode code.
- Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
- Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
- Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

From MSDN:
Use an instance of Lazy to defer the creation of a large or resource-intensive object or the execution of a resource-intensive task, particularly when such creation or execution might not occur during the lifetime of the program.
In addition to James Michael Hare's answer, Lazy provides thread-safe initialization of your value. Take a look at LazyThreadSafetyMode enumeration MSDN entry describing various types of thread safety modes for this class.
It's just part of the horrendous mess which is the Java date/time API. Listing what's wrong with it would take a very long time (and I'm sure I don't know half of the problems). Admittedly working with dates and times is tricky, but aaargh anyway.
Do yourself a favour and use Joda Time instead, or possibly JSR-310.
EDIT: As for the reasons why - as noted in other answers, it could well be due to old C APIs, or just a general feeling of starting everything from 0... except that days start with 1, of course. I doubt whether anyone outside the original implementation team could really state reasons - but again, I'd urge readers not to worry so much about why bad decisions were taken, as to look at the whole gamut of nastiness in java.util.Calendar
and find something better.
One point which is in favour of using 0-based indexes is that it makes things like "arrays of names" easier:
// I "know" there are 12 months
String[] monthNames = new String[12]; // and populate...
String name = monthNames[calendar.get(Calendar.MONTH)];
Of course, this fails as soon as you get a calendar with 13 months... but at least the size specified is the number of months you expect.
This isn't a good reason, but it's a reason...
EDIT: As a comment sort of requests some ideas about what I think is wrong with Date/Calendar:
Date
and Calendar
as different things,
but the separation of "local" vs "zoned" values is missing, as is date/time vs date vs timeDate.toString()
implementation which always uses the system local time zone (that's confused many Stack Overflow users before now)SELECT

Slight change of the accepted answer if you want to grab permissions that are applied at database level in addition to object level. Basically switch to LEFT JOIN

Both methods ensure that your process doesn't end before all of your threads have ended.
The join method has your thread of the main
function explicitly wait for all threads that are to be "joined".
The pthread_exit
method terminates your main
function and thread in a controlled way. main
has the particularity that ending main
otherwise would be terminating your whole process including all other threads.
For this to work, you have to be sure that none of your threads is using local variables that are declared inside them main
function. The advantage of that method is that your main
doesn't have to know all threads that have been started in your process, e.g because other threads have themselves created new threads that main
doesn't know anything about.
So, youtube gives out the iframe tag as follows:
<iframe width="560" height="315" src="https://www.youtube.com/embed/2EIeUlvHAiM" frameborder="0" allowfullscreen></iframe>
In my case, i just changed it to width="100%" and left the rest as is. It's not the most elegant solution (after all, in different devices you'll get weird ratios) But the video itself does not get deformed, just the frame.
I use a pretty hack-ish solution for this in one of my recent applications that works for my purposes, and I find it quicker than writing custom hover settings functions in vanilla js (though, I recognize, maybe not a best practice in most environments..) So, in case you're still interested, here goes.
I create a parent element just for the sake of holding the inline javascript styles, then a child with a className or id that my css stylesheet will latch onto and write the hover style in my dedicated css file. This works because the more granular child element receives the inline js styles via inheritance, but has its hover styles overridden by the css file.
So basically, my actual css file exists for the sole purpose of holding hover effects, nothing else. This makes it pretty concise and easy to manage, and allows me to do the heavy-lifting in my in-line React component styles.
Here's an example:
const styles = {_x000D_

Notice that the "child" inline style does not have a "color" property set. If it did, this would not work because the inline style would take precedence over my stylesheet.
The term upstream also has some unambiguous meaning as comes to the suite of GIT tools, especially relative to tracking
For example :
$git rev-list --count --left-right "@{upstream}"...HEAD >4 12
will print (the last cached value of) the number of commits behind (left) and ahead (right) of your current working branch, relative to the (if any) currently tracking remote branch for this local branch. It will print an error message otherwise:
>error: No upstream branch found for ''
origin
(your forked repo on github) and upstream
(the repo on github you forked from). Those are just interchangeable names, only the 'git@...' url identifies them.Your
.git/config
reads :[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = [email protected]:myusername/reponame.git [remote "upstream"] fetch = +refs/heads/*:refs/remotes/upstream/* url = [email protected]:authorname/reponame.git
it is 'the branch' (if any) on 'said remote', which is tracking the 'current branch' on your 'local repository'.
It's the branch you fetch/pull from whenever you issue a plain
git fetch
/git pull
, without arguments.
Let's say want to set the remote branch origin/master to be the tracking branch for the local master branch you've checked out. Just issue :
$ git branch --set-upstream master origin/master > Branch master set up to track remote branch master from origin.
This adds 2 parameters in
.git/config
:[branch "master"] remote = origin merge = refs/heads/master
now try (provided 'upstream' remote has a 'dev' branch)
$ git branch --set-upstream master upstream/dev > Branch master set up to track remote branch dev from upstream.
.git/config
now reads:[branch "master"] remote = upstream merge = refs/heads/dev
-u --set-upstream
For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument-less git-pull(1) and other commands. For more information, see
branch.<name>.merge
in git-config(1).branch.<name>.merge
Defines, together with
branch.<name>.remote
, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). \ (...)branch.<name>.remote
When in branch < name >, it tells git fetch and git push which remote to fetch from/push to. It defaults to origin if no remote is configured. origin is also used if you are not on any branch.
take a look at git-config(1)
Manual Page
git config --global push.default upstream git config --global push.default tracking (deprecated)
This is to prevent accidental pushes to branches which you’re not ready to push yet.

For committing, I use the following strategies:
commit as often as possible.
Each feature change/bugfix should get its own commit (don't commit many files at once since that will make the history for that file unclear -- e.g. If I change a logging module and a GUI module independently and I commit both at once, both changes will be visible in both file histories. This makes reading a file history difficult),
don't break the build on any commit -- it should be possible to retrieve any version of the repository and build it.
All files that are necessary for building and running the app should be in SVN. Test files and such should not, unless they are part of the unit tests.
You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL
This works using java.util.Scanner and will take multiple "enter" keystrokes:
Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();
while(readString!=null) {
System.out.println(readString);
if (readString.isEmpty()) {
System.out.println("Read Enter Key.");
}
if (scanner.hasNextLine()) {
readString = scanner.nextLine();
} else {
readString = null;
}
}
To break it down:
Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();
These lines initialize a new Scanner
that is reading from the standard input stream (the keyboard) and reads a single line from it.
while(readString!=null) {
System.out.println(readString);
While the scanner is still returning non-null data, print each line to the screen.
if (readString.isEmpty()) {
System.out.println("Read Enter Key.");
}
If the "enter" (or return, or whatever) key is supplied by the input, the nextLine()
method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.
if (scanner.hasNextLine()) {
readString = scanner.nextLine();
} else {
readString = null;
}
Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.
SET NOCOUNT ON even does allows to access to the affected rows like this:
SET NOCOUNT ON
DECLARE @test TABLE (ID int)
INSERT INTO @test
VALUES (1),(2),(3)
DECLARE @affectedRows int = -99
DELETE top (1)
FROM @test
SET @affectedRows = @@rowcount
SELECT @affectedRows as affectedRows

@bdiamante's answer may only partially help you. If you still get a message after you've suppressed warnings, it's because the pandas
library itself is printing the message. There's not much you can do about it unless you edit the Pandas source code yourself. Maybe there's an option internally to suppress them, or a way to override things, but I couldn't find one.
Suppose that you want to ensure a clean working environment. At the top of your script, you put pd.reset_option('all')
. With Pandas 0.23.4, you get the following:
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)
C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning: html.bord
er has been deprecated, use display.html.border instead
(currently both are identical)
warnings.warn(d.msg, FutureWarning)
: boolean
use_inf_as_null had been deprecated and will be removed in a future
version. Use `use_inf_as_na` instead.
C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning:
: boolean
use_inf_as_null had been deprecated and will be removed in a future
version. Use `use_inf_as_na` instead.
warnings.warn(d.msg, FutureWarning)
>>>
Following the @bdiamante's advice, you use the warnings
library. Now, true to it's word, the warnings have been removed. However, several pesky messages remain:
>>> import warnings
>>> warnings.simplefilter(action='ignore', category=FutureWarning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)
: boolean
use_inf_as_null had been deprecated and will be removed in a future
version. Use `use_inf_as_na` instead.
>>>
In fact, disabling all warnings produces the same output:
>>> import warnings
>>> warnings.simplefilter(action='ignore', category=Warning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)
: boolean
use_inf_as_null had been deprecated and will be removed in a future
version. Use `use_inf_as_na` instead.
>>>
In the standard library sense, these aren't true warnings. Pandas implements its own warnings system. Running grep -rn
on the warning messages shows that the pandas
warning system is implemented in core/config_init.py
:
$ grep -rn "html.border has been deprecated"
core/config_init.py:207:html.border has been deprecated, use display.html.border instead
Further chasing shows that I don't have time for this. And you probably don't either. Hopefully this saves you from falling down the rabbit hole or perhaps inspires someone to figure out how to truly suppress these messages!
I uninstalled all parts of SQL Server 2012 using Control Panel in Windows and then reinstalled (choosing "All Features"). Now it works!
I also had the same issue. I also wanted so users could take photos easily while picking photos from the gallery. Couldn't find a native way of doing this therefore I decided to make an opensource project. It is much like MultipleImagePick but just better way of implementing it.

case RESULT_CODE_PICKER_IMAGES:
if(resultCode == Activity.RESULT_OK){
Parcelable[] parcelableUris = data.getParcelableArrayExtra(ImagePickerActivity.TAG_IMAGE_URI);
//Java doesn't allow array casting, this is a little hack
Uri[] uris = new Uri[parcelableUris.length];
System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);
//Do something with the uris array
}
break;
default:
super.onActivityResult(requestCode, resultCode, data);
break;
}
}
The problem is, your template can contain several HTML elements, so MVC won't know to which one to apply your size/class. You'll have to define it yourself.
Make your template derive from your own class called TextBoxViewModel:
public class TextBoxViewModel
{
public string Value { get; set; }
IDictionary<string, object> moreAttributes;
public TextBoxViewModel(string value, IDictionary<string, object> moreAttributes)
{
// set class properties here
}
public string GetAttributesString()
{
return string.Join(" ", moreAttributes.Select(x => x.Key + "='" + x.Value + "'").ToArray()); // don't forget to encode
}
}
In the template you can do this:
<input value="<%= Model.Value %>" <%= Model.GetAttributesString() %> />
In your view you do:
<%= Html.EditorFor(x => x.StringValue) %>
or
<%= Html.EditorFor(x => new TextBoxViewModel(x.StringValue, new IDictionary<string, object> { {'class', 'myclass'}, {'size', 15}}) %>
The first form will render default template for string. The second form will render the custom template.
Alternative syntax use fluent interface:
public class TextBoxViewModel
{
public string Value { get; set; }
IDictionary<string, object> moreAttributes;
public TextBoxViewModel(string value, IDictionary<string, object> moreAttributes)
{
// set class properties here
moreAttributes = new Dictionary<string, object>();
}
public TextBoxViewModel Attr(string name, object value)
{
moreAttributes[name] = value;
return this;
}
}
// and in the view
<%= Html.EditorFor(x => new TextBoxViewModel(x.StringValue).Attr("class", "myclass").Attr("size", 15) %>
Notice that instead of doing this in the view, you may also do this in controller, or much better in the ViewModel:
public ActionResult Action()
{
// now you can Html.EditorFor(x => x.StringValue) and it will pick attributes
return View(new { StringValue = new TextBoxViewModel(x.StringValue).Attr("class", "myclass").Attr("size", 15) });
}
Also notice that you can make base TemplateViewModel class - a common ground for all your view templates - which will contain basic support for attributes/etc.
But in general I think MVC v2 needs a better solution. It's still Beta - go ask for it ;-)
foreach($xml->code as $vals )

Your JSON is not correct. Instead of
JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred.toString()); // <-- toString()
parent.put("auth", auth.toString()); // <-- toString()
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());
write
JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred);
parent.put("auth", auth);
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());
So, the JSONObject.toString() should be called only once for the outer object.
Another thing (most probably not your problem, but I'd like to mention it):
To be sure not to run into encoding problems, you should specify the encoding, if it is not UTF-8
:
con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
con.setRequestProperty("Accept", "application/json");
// ...
OutputStream os = con.getOutputStream();
os.write(parent.toString().getBytes("UTF-8"));
os.close();
I had the same its because of version incompatibility check for version or remove version if using spring boot
If you want to print all the columns in your select clause you can go with the autoprint command.
CREATE OR REPLACE PROCEDURE sps_detail_dtest(v_refcur OUT sys_refcursor)
AS
BEGIN
OPEN v_refcur FOR 'select * from dummy_table';
END;
SET autoprint on;
--calling the procedure
VAR vcur refcursor;
DECLARE
BEGIN
sps_detail_dtest(vrefcur=>:vcur);
END;
Hope this gives you an alternate solution

I ran into this problem.. but within a for loop. The top solution did not work (when using variables (and not strings) for the parameters of the push function), and the others did not account for key values based on variables. I was surprised this approach (which is common in php) worked..
// example dict/json
var iterateDict = {'record_identifier': {'content':'Some content','title':'Title of my Record'},
'record_identifier_2': {'content':'Some different content','title':'Title of my another Record'} };
var array = [];
// key to reduce the 'record' to
var reduceKey = 'title';
for(key in iterateDict)
// ultra-safe variable checking...
if(iterateDict[key] !== undefined && iterateDict[key][reduceKey] !== undefined)
// build element to new array key
array[key]=iterateDict[key][reduceKey];

In my case, the problem was with PUT requests (GET and POST were passing successfully).
Communication went through VPN tunnel and ssh connection. And there was a firewall with default restrictions on PUT requests... PUT requests haven't been passing throughout, to the server...
Problem was solved after exception was added to the firewall for my IP address.
The rvest
along with xml2
is another popular package for parsing html web pages.
library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)
The syntax is easier to use than the xml
package and for most web pages the package provides all of the options ones needs.

You can use prettytable to render the table as text. The trick is to convert the data_frame to an in-memory csv file and have prettytable read it. Here's the code:
from StringIO import StringIO
import prettytable
output = StringIO()
data_frame.to_csv(output)
output.seek(0)
pt = prettytable.from_csv(output)
print pt

echo $d->format("d/m/Y H:i:s"); // or any you want
Result:
09/04/2013 16:37:05
Here is just another option you couold apply for ASP NET MVC.
Normally you shoud use BaseController
class for each Controller
class.
So inside of it's constructor method do following.
public class BaseController : Controller
{
public BaseController()
{
// get the previous url and store it with view model
ViewBag.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;
}
}
And now in ANY view you can do like
<button class="btn btn-success mr-auto" onclick=" window.location.href = '@ViewBag.PreviousUrl'; " style="width:2.5em;"><i class="fa fa-angle-left"></i></button>
Enjoy!
Sometimes just setting canvas's tabindex to '1' (or '0') works. But sometimes - it doesn't, for some strange reason.
In my case (ReactJS app, dynamic canvas el creation and mount) I need to call canvasEl.focus() to fix it. Maybe this is somehow related to React (my old app based on KnockoutJS works without '..focus()' )
HTML Date Picker You can refer this.
I like to use presence
, inspired from Ruby on Rails:
$.fn.presence = function () {
return this.length !== 0 && this;
}
Your example becomes:
alert($('#notAnElement').presence() || "No object found");
I find it superior to the proposed $.fn.exists
because you can still use boolean operators or if
, but the truthy result is more useful. Another example:
$ul = $elem.find('ul').presence() || $('<ul class="foo">').appendTo($elem)
$ul.append('...')
The correct way of setting a listener to a fragment is by setting it when it is attached. The problem I had was that onAttachFragment() was never called. After some investigation I realised that I had been using getFragmentManager instead of getChildFragmentManager
Here is how I do it:
MyDialogFragment dialogFragment = MyDialogFragment.newInstance("title", "body");
dialogFragment.show(getChildFragmentManager(), "SOME_DIALOG");
Attach it in onAttachFragment:
@Override
public void onAttachFragment(Fragment childFragment) {
super.onAttachFragment(childFragment);
if (childFragment instanceof MyDialogFragment) {
MyDialogFragment dialog = (MyDialogFragment) childFragment;
dialog.setListener(new MyDialogFragment.Listener() {
@Override
public void buttonClicked() {
}
});
}
}
I saw some contradictions in the answers above, I just tried the following on Oracle 12c and the following is correct :
LEFT OUTER JOIN
SELECT *
FROM A, B
WHERE A.column = B.column(+)
RIGHT OUTER JOIN
SELECT *
FROM A, B
WHERE B.column(+) = A.column
You should create a ModelForm
(docs), which has a field that uses the PasswordInput
widget from the forms library.
It would look like this:
from django import models
class User(models.Model):
username = models.CharField(max_length=100)
password = models.CharField(max_length=50)
from django import forms
class UserForm(forms.ModelForm):
class Meta:
model = User
widgets = {
'password': forms.PasswordInput(),
}
For more about using forms in a view, see this section of the docs.
DateTime.Now.DayOfWeek
quite easy to guess actually.
for any given date:
DateTime dt = //....
DayOfWeek dow = dt.DayOfWeek; //enum
string str = dow.ToString(); //string
If a directory has spaces in, put quotes around it. This includes the program you're calling, not just the arguments

From the Metaprogramming Ruby book,
The
require()
method is quite similar toload()
, but it’s meant for a different purpose. You useload()
to execute code, and you userequire()
to import libraries.
Maybe maven encoding you KeyStore, you can set filtering=false to fix this problem.

JPA was designed to provide an automatic mapping between Objects and a relational database. Since Integer is not a persistant entity, why do you need to use JPA ? A simple JDBC request will work fine.
The put method in HashMap is defined like this:
Object put(Object key, Object value)
key is the first parameter, so in your put, "one" is the key. You can't easily look up by value in a HashMap, if you really want to do that, it would be a linear search done by calling entrySet()
, like this:
for (Map.Entry<Object, Object> e : hashmap.entrySet()) {
Object key = e.getKey();
Object value = e.getValue();
}
However, that's O(n) and kind of defeats the purpose of using a HashMap unless you only need to do it rarely. If you really want to be able to look up by key or value frequently, core Java doesn't have anything for you, but something like BiMap from the Google Collections is what you want.
if not exists (select * from sysobjects where name='cars' and xtype='U')
create table cars (
Name varchar(64) not null
)
go
The above will create a table called cars
if the table does not already exist.
I realize this is a very old question, but hopefully this will help someone else out as I came upon this post looking for the same thing. I had a similar issue, just that my metadata was a Guid and int. The solution is the same though. You can just make the needed metadata part of the URL.
POST accepting method in your "Controller" class:
public Task<HttpResponseMessage> PostFile(string name, float latitude, float longitude)
{
//See http://stackoverflow.com/a/10327789/431906 for how to accept a file
return null;
}
Then in whatever you're registering routes, WebApiConfig.Register(HttpConfiguration config) for me in this case.
config.Routes.MapHttpRoute(
name: "FooController",
routeTemplate: "api/{controller}/{name}/{latitude}/{longitude}",
defaults: new { }
);
With -Raw
you should get what you expect
typeof
condition is used to check variable type, if you are check variable type in if-else condition
e.g.
if(typeof Varaible_Name "undefined")
{
}
When your form is maximized, set its minimum size = max size, so user cannot resize it.
this.WindowState = FormWindowState.Maximized;
this.MinimumSize = this.Size;
this.MaximumSize = this.Size;
On the contrary, I do think working with list
makes it easy to automate such things.
Here is one solution (I stored your four dataframes in folder temp/
).
filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)
It is important to store the full path for your files (as I did with full.names
), otherwise you have to paste the working directory, e.g.
filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")
will work too. Note that I used substr
to extract file names while discarding full path.
You can access your summary tables as follows:
> res$`df4.csv`
A B
Min. :0.00 Min. : 1.00
1st Qu.:1.25 1st Qu.: 2.25
Median :3.00 Median : 6.00
Mean :3.50 Mean : 7.00
3rd Qu.:5.50 3rd Qu.:10.50
Max. :8.00 Max. :16.00
If you really want to get individual summary tables, you can extract them afterwards. E.g.,
for (i in 1:length(res))
assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])
Apache Commons Collections 4 has a partition method in the ListUtils
class. Here’s how it works:
import org.apache.commons.collections4.ListUtils;
...
int targetSize = 100;
List<Integer> largeList = ...
List<List<Integer>> output = ListUtils.partition(largeList, targetSize);
here is how I handled if else if situation
if %env%==dev (
echo "dev env selected selected"
) else (
if %env%==prod (
echo "prod env selected"
)
)
Note it is not the same as if-elseif block as the other programming languages like C++ or Java but it will do what you need to do
Change the definition of multiply to take additional unknown arguments:

I'm using tesseract OCR engine with TessNet2 (a C# wrapper - http://www.pixel-technology.com/freeware/tessnet2/).
Some basic code:
using tessnet2;
...
Bitmap image = new Bitmap(@"u:\user files\bwalker\2849257.tif");
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.,$-/#&=()\"':?"); // Accepted characters
ocr.Init(@"C:\Users\bwalker\Documents\Visual Studio 2010\Projects\tessnetWinForms\tessnetWinForms\bin\Release\", "eng", false); // Directory of your tessdata folder
List<tessnet2.Word> result = ocr.DoOCR(image, System.Drawing.Rectangle.Empty);
string Results = "";
foreach (tessnet2.Word word in result)
{
Results += word.Confidence + ", " + word.Text + ", " + word.Left + ", " + word.Top + ", " + word.Bottom + ", " + word.Right + "\n";
}
The IPv6 addresses for fields like RemoteAddr
from http.Request
are formatted as "[::1]:53343"
So net.SplitHostPort
works great:
package main
import (
"fmt"
"net"
)
func main() {
host1, port, err := net.SplitHostPort("127.0.0.1:5432")
fmt.Println(host1, port, err)
host2, port, err := net.SplitHostPort("[::1]:2345")
fmt.Println(host2, port, err)
host3, port, err := net.SplitHostPort("localhost:1234")
fmt.Println(host3, port, err)
}
Output is:
127.0.0.1 5432 <nil>
::1 2345 <nil>
localhost 1234 <nil>
Solution 1 (Elegant approach with great user experience)
HTML
<input id="inputID" class="uppercase" name="inputName" value="" />
CSS
.uppercase{
text-transform: uppercase;
}
JS
$('#inputID').on('blur', function(){
this.value = this.value.toUpperCase();
});
By using CSS text-transform: uppercase;
you'll eliminate the animation of lower to uppercase as the user types into the field.
Use blur
event to handle converting to uppercase. This happens behind the scene as CSS took care of the user's visually appealing masking.
Solution 2 (Great, but less elegant)
If you insist on using keyup
, here it is...
$('#inputID').on('keyup', function(){
var caretPos = this.selectionStart;
this.value = this.value.toUpperCase();
this.setSelectionRange(caretPos, caretPos);
});
User would notice the animation of lowercase to uppercase as they type into the field. It gets the job done.
Solution 3 (Just get the job done)
$('#inputID').on('keyup', function(){
this.value = this.value.toUpperCase();
});
This method is most commonly suggested but I do not recommend.
The downside of this solution is you'll be annoying the user as the cursor's caret position keeps jumping to the end of the text after every key input. Unless you know your users will never encounter typos or they will always clear the text and retype every single time, this method works.
I encountered the same problem after freshly installing git on Windows 10 and running it for the first time. Restarting the bash window solved the problem.
Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

You can get a pretty coarse idea of the OS you're using by checking sys.platform
.
Once you have that information you can use it to determine if calling something like os.uname()
is appropriate to gather more specific information. You could also use something like Python System Information on unix-like OSes, or pywin32 for Windows.
There's also psutil if you want to do more in-depth inspection without wanting to care about the OS.
Use the Microsoft.VisualBasic.FileIO.TextFieldParser
class. This will handle parsing a delimited file, TextReader
or Stream
where some fields are enclosed in quotes and some are not.
For example:
using Microsoft.VisualBasic.FileIO;
string csv = "2,1016,7/31/2008 14:22,Geoff Dalgas,6/5/2011 22:21,http://stackoverflow.com,\"Corvallis, OR\",7679,351,81,b437f461b3fd27387c5d8ab47a293d35,34";
TextFieldParser parser = new TextFieldParser(new StringReader(csv));
// You can also read from a file
// TextFieldParser parser = new TextFieldParser("mycsvfile.csv");
parser.HasFieldsEnclosedInQuotes = true;
parser.SetDelimiters(",");
string[] fields;
while (!parser.EndOfData)
{
fields = parser.ReadFields();
foreach (string field in fields)
{
Console.WriteLine(field);
}
}
parser.Close();
This should result in the following output:
2 1016 7/31/2008 14:22 Geoff Dalgas 6/5/2011 22:21 http://stackoverflow.com Corvallis, OR 7679 351 81 b437f461b3fd27387c5d8ab47a293d35 34
See Microsoft.VisualBasic.FileIO.TextFieldParser for more information.
You need to add a reference to Microsoft.VisualBasic
in the Add References .NET tab.
An even simpler awk solution w/o a program:
awk -v ORS='\r\n' '1' unix.txt > dos.txt
Technically '1' is your program, b/c awk requires one when given option.
UPDATE: After revisiting this page for the first time in a long time I realized that no one has yet posted an internal solution, so here is one:
while IFS= read -r line;
do printf '%s\n' "${line%$'\r'}";
done < dos.txt > unix.txt
The only benefit that I can think of is Transactional feature, rest all can be done by using Kafka
There's nothing wrong with either version of your code. Whatever is causing this, that's not it.
Have you triple checked your locator? Your element definitely has name=submit not id=submit?
Methods should be like this:
[Route("api/[controller]")]
public class PersonsController : Controller
{
[HttpGet("{id}")]
public Person Get(int id)
[HttpGet]
public Person[] Get([FromQuery] string firstName, [FromQuery] string lastName, [FromQuery] string address)
}
Take note that second method returns an array of objects and controller name is in plurar (Persons not Person).
So if you want to get resource by id it will be:
api/persons/1
if you want to take objects by some search criteria like first name and etc, you can do search like this:
api/persons?firstName=Name&...
And moving forward if you want to take that person orders (for example), it should be like this:
api/persons/1/orders?skip=0&take=20
And method in the same controller:
[HttpGet("{personId}/orders")]
public Orders[] Get(int personId, int skip, int take, etc..)

I'm pretty sure this isn't the BEST way, but you could set the MinimumSize

properties to the same value. That will stop it.
this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -
Used the cmd to install python and flask after creating environment as suggested above.

Obviously kept the correct python interpreter (the one in the environment) everywhere.
You can extract the html string from the PartialViewResult object, similar to the answer to this thread:
PartialViewResult and ViewResult both derive from ViewResultBase, so the same method should work on both.
Using the code from the thread above, you would be able to use:
public ActionResult ReturnSpecialJsonIfInvalid(AwesomenessModel model)
{
if (ModelState.IsValid)
{
if(Request.IsAjaxRequest())
return PartialView("NotEvil", model);
return View(model)
}
if(Request.IsAjaxRequest())
{
return Json(new { error = true, message = RenderViewToString(PartialView("Evil", model))});
}
return View(model);
}

I try different solutions from this thread and in the end I use this one:
def egcd(a, b):
lastremainder, remainder = abs(a), abs(b)
x, lastx, y, lasty = 0, 1, 1, 0
while remainder:
lastremainder, (quotient, remainder) = remainder, divmod(lastremainder, remainder)
x, lastx = lastx - quotient*x, x
y, lasty = lasty - quotient*y, y
return lastremainder, lastx * (-1 if a < 0 else 1), lasty * (-1 if b < 0 else 1)
def modinv(a, m):
g, x, y = self.egcd(a, m)
if g != 1:
raise ValueError('modinv for {} does not exist'.format(a))
return x % m
That's How Python works. Try this :

Such that you can directly use the name without the enclosing module.Or just import the module and prepend 'sqlitedbx.' to your function,class etc

Direct Closure serialisation is not allowed by PHP. But you can use powefull class like PHP Super Closure : https://github.com/jeremeamia/super_closure
This class is really simple to use and is bundled into the laravel framework for the queue manager.

$helloWorld = new SerializableClosure(function ($name = 'World') use ($greeting) {

});
$serialized = serialize($helloWorld);

In my opinion, android.text.format.DateFormat.getDateFormat(context)
makes me confused because this method returns java.text.DateFormat
rather than android.text.format.DateFormat
- -".
So, I use the fragment code as below to get the current date/time in my format.
android.text.format.DateFormat df = new android.text.format.DateFormat();
df.format("yyyy-MM-dd hh:mm:ss a", new java.util.Date());
or
android.text.format.DateFormat.format("yyyy-MM-dd hh:mm:ss a", new java.util.Date());
In addition, you can use others formats. Follow DateFormat.
you are getting math domain error for either one of the reason : either you are trying to use a negative number inside log function or a zero value.

var getElement = document.getElementById('myID');
if (document.activeElement === getElement) {
$(document).keydown(function(event) {
if (event.which === 40) {
console.log('keydown pressed')
}
});
}
Thank you...

Hemant and Vikram's answers didn't quite work for me outright in Chrome. The event.preventDefault(); script prevented the the page from submitting regardless of passing or failing the validation. Instead, I had to move the event.preventDefault(); into the if statement as follows:
if(check if your conditions are not satisfying)
{
event.preventDefault();
alert("validation failed false");
returnToPreviousPage();
return false;
}
alert("validations passed");
return true;
}
Thanks to Hemant and Vikram for putting me on the right track.
Thanks to Giles Gardam for his answer, but it addresses only longitude and not latitude. A complete solution should calculate the zoom level needed for latitude and the zoom level needed for longitude, and then take the smaller (further out) of the two.
Here is a function that uses both latitude and longitude:
function getBoundsZoomLevel(bounds, mapDim) {
var WORLD_DIM = { height: 256, width: 256 };
var ZOOM_MAX = 21;
function latRad(lat) {
var sin = Math.sin(lat * Math.PI / 180);
var radX2 = Math.log((1 + sin) / (1 - sin)) / 2;
return Math.max(Math.min(radX2, Math.PI), -Math.PI) / 2;
}
function zoom(mapPx, worldPx, fraction) {
return Math.floor(Math.log(mapPx / worldPx / fraction) / Math.LN2);
}
var ne = bounds.getNorthEast();
var sw = bounds.getSouthWest();
var latFraction = (latRad(ne.lat()) - latRad(sw.lat())) / Math.PI;
var lngDiff = ne.lng() - sw.lng();
var lngFraction = ((lngDiff < 0) ? (lngDiff + 360) : lngDiff) / 360;
var latZoom = zoom(mapDim.height, WORLD_DIM.height, latFraction);
var lngZoom = zoom(mapDim.width, WORLD_DIM.width, lngFraction);
return Math.min(latZoom, lngZoom, ZOOM_MAX);
}
Parameters:
The "bounds" parameter value should be a google.maps.LatLngBounds
object.
The "mapDim" parameter value should be an object with "height" and "width" properties that represent the height and width of the DOM element that displays the map. You may want to decrease these values if you want to ensure padding. That is, you may not want map markers within the bounds to be too close to the edge of the map.
If you are using the jQuery library, the mapDim
value can be obtained as follows:
var $mapDiv = $('#mapElementId');
var mapDim = { height: $mapDiv.height(), width: $mapDiv.width() };
If you are using the Prototype library, the mapDim value can be obtained as follows:
var mapDim = $('mapElementId').getDimensions();
Return Value:
The return value is the maximum zoom level that will still display the entire bounds. This value will be between 0
and the maximum zoom level, inclusive.
The maximum zoom level is 21. (I believe it was only 19 for Google Maps API v2.)
Explanation:
Google Maps uses a Mercator projection. In a Mercator projection the lines of longitude are equally spaced, but the lines of latitude are not. The distance between lines of latitude increase as they go from the equator to the poles. In fact the distance tends towards infinity as it reaches the poles. A Google Maps map, however, does not show latitudes above approximately 85 degrees North or below approximately -85 degrees South. (reference) (I calculate the actual cutoff at +/-85.05112877980658 degrees.)
This makes the calculation of the fractions for the bounds more complicated for latitude than for longitude. I used a formula from Wikipedia to calculate the latitude fraction. I am assuming this matches the projection used by Google Maps. After all, the Google Maps documentation page I link to above contains a link to the same Wikipedia page.
Other Notes:
And also if the input box/button has to remain disable, then simply
<button disabled>
or <input disabled>
works.
On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE
, can be tampered with so always use server side validation.
<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="file" id="file" />
<input type="submit" name="submit" value="Submit" />
</form>
<script>
document.forms[0].addEventListener('submit', function( evt ) {
var file = document.getElementById('file').files[0];
if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
//Submit form
} else {
//Prevent default and display error
evt.preventDefault();
}
}, false);
</script>
On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize
. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE
has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.
On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES
array to find out the upload size. (Docs on the contents of $_FILES
can be found below the MAX_FILE_SIZE
docs)
upload.php
<?php
if(isset($_FILES['file'])) {
if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
// File too big
} else {
// File within size restrictions
}
}
Have you tried..
if (getActivity() instanceof NameOfYourActivity){
//Do something
}
another alternative, just in case you want to have a shell script which creates the database if it does not exist and otherwise just keeps it as it is:
psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'my_db'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE my_db"
I found this to be helpful in devops provisioning scripts, which you might want to run multiple times over the same instance.
For those of you who would like an explanation:
-c = run command in database session, command is given in string
-t = skip header and footer
-q = silent mode for grep
|| = logical OR, if grep fails to find match run the subsequent command
mysqli is provided by php-mysql-5.3.3-40.el6_6.x86_64
You may need to try the following
yum install php-mysql-5.3.3-40.el6_6.x86_64
Seems like a Permissions Issue. I was facing the same error. But when I ran it from the root account, it worked. So either give the read permission to the file using chmod (in linux) or run your script after logging in as a root user.
You can replace IList<DzieckoAndOpiekun> resultV
with var resultV
.
I show you my example with modal windows...you create your modal and give it an id then In your table you have tr section, just ad the first line you see below (don't forget to set the on the first row like this
<tr onclick="input" data-toggle="modal" href="#the name for my modal windows" >
<td><label>Some value here</label></td>
</tr>
if (data?.trim().length > 0) {
//use data
}
the ?.
optional chaining operator will short-circuit and return undefined
if data is nullish
(null
or undefined
) which will evaluate to false in the if
expression.
Check this simple method (It is recommended to put This method in your dateUtility
public static bool isOverlapDates(DateTime dtStartA, DateTime dtEndA, DateTime dtStartB, DateTime dtEndB)
{
return dtStartA < dtEndB && dtStartB < dtEndA;
}

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...
...create an NSDictionary
NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects
forKeys:keys];
...iterate over it
for (id key in dictionary) {
NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}
...make it mutable
NSMutableDictionary *mutableDict = [dictionary mutableCopy];
Note: historic version before 2010: [[dictionary mutableCopy] autorelease]
...and alter it
[mutableDict setObject:@"value3" forKey:@"key3"];
...then store it to a file
[mutableDict writeToFile:@"path/to/file" atomically:YES];
...and read it back again
NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];
...read a value
NSString *x = [anotherDict objectForKey:@"key1"];
...check if a key exists
if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");
...use scary futuristic syntax
From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]
//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)
Try /me/taggable_friends?limit=5000

Use intptr_t
and uintptr_t
.
To ensure it is defined in a portable way, you can use code like this:
#if defined(__BORLANDC__)
typedef unsigned char uint8_t;
typedef __int64 int64_t;
typedef unsigned long uintptr_t;
#elif defined(_MSC_VER)
typedef unsigned char uint8_t;
typedef __int64 int64_t;
#else
#include <stdint.h>
#endif
Just place that in some .h file and include wherever you need it.
Alternatively, you can download Microsoft’s version of the stdint.h
file from here or use a portable one from here.
There are some good answers here already. But it's worthwhile to drive home the difference in parallelism offered:
success()
returns the original promisethen()
returns a new promiseThe difference is then()
drives sequential operations, since each call returns a new promise.
$http.get(/*...*/).
then(function seqFunc1(response){/*...*/}).
then(function seqFunc2(response){/*...*/})
$http.get()
seqFunc1()
seqFunc2()
success()
drives parallel operations, since handlers are chained on the same promise.
$http(/*...*/).
success(function parFunc1(data){/*...*/}).
success(function parFunc2(data){/*...*/})
$http.get()
parFunc1()
, parFunc2()
in parallelIf you have lots of commits and you only want to squash the last X commits, find the commit ID of the commit from which you want to start squashing and do
git rebase -i <that_commit_id>
Then proceed as described in leopd's answer, changing all the pick
s to squash
es except the first one.

Another simple solution is to add jackson-databind dependency in POM.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.1</version>
</dependency>
Keep Rest of the code as it is.
When indexed view is not an option, and quick updates are not necessary, you can create a hack cache table:
select * into cachetablename from myviewname
alter table cachetablename add primary key (columns)
-- OR alter table cachetablename add rid bigint identity primary key
create index...
then sp_rename view/table or change any queries or other views that reference it to point to the cache table.
schedule daily/nightly/weekly/whatnot refresh like
begin transaction
truncate table cachetablename
insert into cachetablename select * from viewname
commit transaction
NB: this will eat space, also in your tx logs. Best used for small datasets that are slow to compute. Maybe refactor to eliminate "easy but large" columns first into an outer view.
You should enable the management plugin.
rabbitmq-plugins enable rabbitmq_management
See here:
http://www.rabbitmq.com/plugins.html
And here for the specifics of management.
http://www.rabbitmq.com/management.html
Finally once set up you will need to follow the instructions below to install and use the rabbitmqadmin tool. Which can be used to fully interact with the system. http://www.rabbitmq.com/management-cli.html
For example:
rabbitmqadmin get queue=<QueueName> requeue=false
will give you the first message off the queue.
There is a simpler solution
if (inputDate.getDate() === todayDate.getDate()) {
// do stuff
}
like that you don't loose the time attached to inputDate
if any
You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.
used like: window.Promise
https://www.npmjs.com/package/promise-polyfill
If you want more information on Polyfills check out the following MDN web doc https://developer.mozilla.org/en-US/docs/Glossary/Polyfill
List<Person> roster = ...;
Map<String, Person> map =
roster
.stream()
.collect(
Collectors.toMap(p -> p.getLast(), p -> p)
);
that would be the translation, but i havent run this or used the API. most likely you can substitute p -> p, for Function.identity(). and statically import toMap(...)
Simply adding docker
as a supplementary group for the jenkins
user
sudo usermod -a -G docker jenkins
is not always enough when using a Docker image as the Jenkins Agent. That is, if your Jenkinsfile
starts with pipeline{agent{dockerfile
or pipeline{agent{image
:
pipeline {
agent {
dockerfile {
filename 'Dockerfile.jenkinsAgent'
}
}
stages {
This is because Jenkins performs a docker run
command, which results in three problems.
docker run
does not do a login to the container (it's more like a sudo
).Making the Docker programs available within the Docker image simply requires running the Docker installation steps in your Dockerfile:
# Dockerfile.jenkinsAgent
FROM debian:stretch-backports
# Install Docker in the image, which adds a docker group
RUN apt-get -y update && \
apt-get -y install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release \
software-properties-common
RUN curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
RUN add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/debian \
$(lsb_release -cs) \
stable"
RUN apt-get -y update && \
apt-get -y install \
docker-ce \
docker-ce-cli \
containerd.io
...
As has been said before, fixing the second problem means running the Jenkins Docker container so it shares the Docker daemon socket with the Docker daemon that is outside the container. So you need to tell Jenkins to run the Docker container with that sharing, thus:
pipeline {
agent {
dockerfile {
filename 'Dockerfile.jenkinsAgent'
args '-v /var/run/docker.sock:/var/run/docker.sock'
}
}
The ideal fix to the third problem would be set up supplementary groups for the Agent. That does not seem possible. The only fix I'm aware of is to run the Agent with the Jenkins UID and the Docker GID (the socket has group write permission and is owned by root.docker
). But in general, you do not know what those IDs are (they were allocated when the useradd ... jenkins
and groupadd ... docker
ran when Jenkins and Docker were installed on the host). And you can not simply tell Jenkins to user user jenkins
and group docker
args '-v /var/run/docker.sock:/var/run/docker.sock -u jenkins:docker'
because that tells Docker to use the user and group that are named jenkins
and docker
within the image, and your Docker image probably does not have the jenkins
user and group, and even if it did there would be no guarantee it would have the same UID and GID as the host, and there is similarly no guarantee that the docker
GID is the same
Fortunately, Jenkins runs the docker build
command for your Dockerfile in a script, so you can do some shell-script magic to pass through that information as Docker build arguments:
pipeline {
agent {
dockerfile {
filename 'Dockerfile.jenkinsAgent'
additionalBuildArgs '--build-arg JENKINSUID=`id -u jenkins` --build-arg JENKINSGID=`id -g jenkins` --build-arg DOCKERGID=`stat -c %g /var/run/docker.sock`'
args '-v /var/run/docker.sock:/var/run/docker.sock -u jenkins:docker'
}
}
That uses the id
command to get the UID and GID of the jenkins
user and the stat
command to get information about the Docker socket.
Your Dockerfile can use that information to setup a jenkins
user and docker
group for the Agent, using groupadd
, groupmod
and useradd
:
# Dockerfile.jenkinsAgent
FROM debian:stretch-backports
ARG JENKINSUID
ARG JENKINSGID
ARG DOCKERGID
...
# Install Docker in the image, which adds a docker group
RUN apt-get -y update && \
apt-get -y install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release \

RUN apt-get -y update && \

The message “Already up-to-date” means that all the changes from the branch you’re trying to merge have already been merged to the branch you’re currently on. More specifically it means that the branch you’re trying to merge is a parent of your current branch. Congratulations, that’s the easiest merge you’ll ever do. :)
Use gitk
to take a look at your repository. The label for the “test” branch should be somewhere below your “master” branch label.
Your branch is up-to-date with respect to its parent. According to merge there are no new changes in the parent since the last merge. That does not mean the branches are the same, because you can have plenty of changes in your working branch and it sounds like you do.
Edit 10/12/2019:
Per Charles Drake in the comment to this answer, one solution to remediate the problem is:
git checkout master
git reset --hard test
This brings it back to the 'test' level.
Then do:
git push --force origin master
in order to force changes back to the central repo.
Try this
DT <- data.table(X1 = c("a", "b"), X2 = c(1,2), X3 = c("hello", "you"))
changeCols <- colnames(DT)[which(as.vector(DT[,lapply(.SD, class)]) == "character")]
DT[,(changeCols):= lapply(.SD, as.factor), .SDcols = changeCols]

A list comprehension is your best bet for the most Pythonic (and fastest) way to do this:
[int(i.days) for i in (df.B - df.A)]
If your columns aren't in datetime format. The shorter syntax would be: df.A = pd.to_datetime(df.A)
The Major difference is Given Below -
1: Constructor must have same name as the class name while this is not the case of methods
class Calendar{
int year = 0;
int month= 0;
//constructor
public Calendar(int year, int month){
this.year = year;
this.month = month;
System.out.println("Demo Constructor");
}
//Method
public void Display(){
System.out.println("Demo method");
}
}
2: Constructor initializes objects of a class whereas method does not. Methods performs operations on objects that already exist. In other words, to call a method we need an object of the class.
public class Program {
public static void main(String[] args) {
//constructor will be called on object creation
Calendar ins = new Calendar(25, 5);
//Methods will be called on object created
ins.Display();
}
}
3: Constructor does not have return type but a method must have a return type
class Calendar{
//constructor – no return type
public Calendar(int year, int month){
}
//Method have void return type
public void Display(){
System.out.println("Demo method");
}
}
I will suppose your JPanel contains JTextField, for the sake of the demo.
Those components provides JTextComponent#setMargin()
method which seems to be what you're looking for.
If you're looking for an empty border of any size around your text, well, use EmptyBorder

COUNT_NUMBER NUMBER := 0;
cur_id NUMBER;

SELECT COUNT (*)
INTO COUNT_NUMBER
FROM USER_SEQUENCES
WHERE SEQUENCE_NAME = SEQ_NAME;
DBMS_OUTPUT.PUT_LINE (SEQ_NAME || '>' || COUNT_NUMBER);
IF COUNT_NUMBER = 0
THEN
--DBMS_OUTPUT.PUT_LINE('DROP SEQUENCE ' || SEQ_NAME);
-- EXECUTE IMMEDIATE 'DROP SEQUENCE ' || SEQ_NAME;
-- ELSE
SELECT 'CREATE SEQUENCE COMPTABILITE.' || SEQ_NAME || ' START WITH ' || ROUND (DBMS_RANDOM.VALUE (100000000000, 999999999999), 0) || ' INCREMENT BY 1'

cur_id := DBMS_SQL.OPEN_CURSOR;

This started happening to my site after I enabled namespace and custom Open Graph actions and objects. Once you enable it, you lose support for standard object types such as bar, or in my case article. (or it's possible Facebook may have deprecated certain types, I'm not 100% sure) When no supported type is specified, Facebook defaults to website.
To fix this what you need to do is go into your app dashboard, select your app, then go to the Open Graph section. Under "Object Types", define your own types, such as "bar."
Next you will have to change your meta tags to look like this:
<meta property="og:type" content="your_namespace:your_object_type" />
If you click on "Get Code" next to the object type in the dashboard, Facebook will provide you with an example of meta tags to use.
For td elements line-height will successfully allow you to resize the border-height as SPrince mentioned.
For other elements such as list items, you can control the border height with line-height and the height of the actual element with margin-top and margin-bottom.
Here is a working example of both: http://jsfiddle.net/byronj/gLcqu6mg/
An example with list items:
li {
list-style: none;
padding: 0 10px;
display: inline-block;
border-right: 1px solid #000;
line-height: 5px;
margin: 20px 0;
}
<ul>
<li>cats</li>
<li>dogs</li>
<li>birds</li>
<li>swine!</li>
</ul>
You can save image , save the file in your current directory application and move the file to any directory .
Bitmap btm = new Bitmap(image.width,image.height);
Image img = btm;
img.Save(@"img_" + x + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
FileInfo img__ = new FileInfo(@"img_" + x + ".jpg");
img__.MoveTo("myVideo\\img_" + x + ".jpg");
Basically local variables aren't automatically initialized. Hence using them without initializing would result in an exception.
Only the following variables are automatically initialized to their default values:
The default values are as follows (assigned in default constructor of a class):
As far as later parts of your question are conerned:
I can use pointers, but I am a bit afraid of using them.
If you need a dynamic array, you can't escape pointers. Why are you afraid though? They won't bite (as long as you're careful, that is). There's no built-in dynamic array in C, you'll just have to write one yourself. In C++, you can use the built-in std::vector
class. C# and just about every other high-level language also have some similar class that manages dynamic arrays for you.
If you do plan to write your own, here's something to get you started: most dynamic array implementations work by starting off with an array of some (small) default size, then whenever you run out of space when adding a new element, double the size of the array. As you can see in the example below, it's not very difficult at all: (I've omitted safety checks for brevity)
typedef struct {
int *array;

void initArray(Array *a, size_t initialSize) {
a->array = malloc(initialSize * sizeof(int));
a->used = 0;
a->size = initialSize;
}
void insertArray(Array *a, int element) {
// a->used is the number of used entries, because a->array[a->used++] updates a->used only *after* the array has been accessed.
// Therefore a->used can go up to a->size
if (a->used == a->size) {
a->size *= 2;
a->array = realloc(a->array, a->size * sizeof(int));

Using it is just as simple:
Array a;
int i;
initArray(&a, 5); // initially 5 elements
for (i = 0; i < 100; i++)
insertArray(&a, i); // automatically resizes as necessary
printf("%d\n", a.array[9]); // print 10th element
printf("%d\n", a.used); // print number of elements
freeArray(&a);
You simply type vim
into the terminal to open it and start a new file.
You can pass a filename as an option and it will open that file, e.g. vim main.c
. You can open multiple files by passing multiple file arguments.
Vim has different modes, unlike most editors you have probably used. You begin in NORMAL
mode, which is where you will spend most of your time once you become familiar with vim.
To return to NORMAL
mode after changing to a different mode, press Esc. It's a good idea to map your Caps Lock key to Esc, as it's closer and nobody really uses the Caps Lock key.
The first mode to try is INSERT
mode, which is entered with a for append after cursor, or i for insert before cursor.
To enter VISUAL
mode, where you can select text, use v. There are many other variants of this mode, which you will discover as you learn more about vim.
To save your file, ensure you're in NORMAL
mode and then enter the command :w
. When you press :
, you will see your command appear in the bottom status bar. To save and exit, use :x
. To quit without saving, use :q
. If you had made a change you wanted to discard, use :q!
.
You can edit your ~/.vimrc
file to configure vim to your liking. It's best to look at a few first (here's mine) and then decide which options suits your style.
This is how mine looks:
To get the file explorer on the left, use NERDTree. For the status bar, use vim-airline. Finally, the color scheme is solarized.
You can use man vim
for some help inside the terminal. Alternatively, run vimtutor
which is a good hands-on starting point.
It's a good idea to print out a Vim Cheatsheet and keep it in front of you while you're learning vim.
Good luck!
You can check an example in Plunker over here plunker example filters
filter() {
let storeId = 1;
this.bookFilteredList = this.bookList
.filter((book: Book) => book.storeId === storeId);
this.bookList = this.bookFilteredList;
}
Aliases can be used only if they were introduced in the preceding step. So aliases in the SELECT
clause can be used in the ORDER BY
but not the GROUP BY
clause.

Hope this helps.
you can do like this also
long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 }};
for (int i = 0; i < arr.GetLength(0); i++)
{
for (int j = 0; j < arr.GetLength(1); j++)
{
Console.Write(arr[i,j]+" ");
}
Console.WriteLine();
}

I like the way Facebook and others render an image of your email address.
I have also used The Enkoder in the past - thought it was very good to be honest!
to get IMEI (international mobile equipment identifier)
public String getIMEI(Activity activity) {
TelephonyManager telephonyManager = (TelephonyManager) activity
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getDeviceId();
}
to get device unique id
public String getDeviceUniqueID(Activity activity){
String device_unique_id = Secure.getString(activity.getContentResolver(),
Secure.ANDROID_ID);
return device_unique_id;
