I don´t know how to do it using code, but for those who don't mind using a plugin. This is a great one that works for me:
Here's a simple script that wraps up using the dd
approach mentioned here:
#!/usr/bin/env bash
function show_help()
{
IT="
extracts characters X to Y from stdin or FILE
usage: X Y {FILE}
e.g.
2 10 /tmp/it => extract chars 2-10 from /tmp/it
EOF
"
echo "$IT"
exit
}
if [ "$1" == "help" ]
then
show_help
fi
if [ -z "$1" ]
then
show_help
fi
FROM=$1
TO=$2
COUNT=`expr $TO - $FROM + 1`
if [ -z "$3" ]
then
dd skip=$FROM count=$COUNT bs=1 2>/dev/null
else
dd skip=$FROM count=$COUNT bs=1 if=$3 2>/dev/null
fi
All proposed solutions didn't work for me but the closest one was from @Rishii.
I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.
.directive('jsr310Compatible', ['dateFilter', 'dateParser', function(dateFilter, dateParser) {
return {
restrict: 'EAC',
require: 'ngModel',
priority: 1,
link: function(scope, element, attrs, ngModel) {
var dateFormat = 'yyyy-MM-dd';
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue, dateFormat);
});
ngModel.$validators.date = function (modelValue, viewValue) {
var value = modelValue || viewValue;
if (!attrs.ngRequired && !value) {
return true;
}
if (angular.isNumber(value)) {
value = new Date(value);
}
if (!value) {
return true;
}
else if (angular.isDate(value) && !isNaN(value)) {
return true;
}
else if (angular.isString(value)) {
var date = dateParser.parse(value, dateFormat);
return !isNaN(date);
}
else {
return false;
}
};
}
};
}])
Here's your example in the "one" line.
this.$OuterDiv = $('<div></div>')
.hide()
.append($('<table></table>')
.attr({ cellSpacing : 0 })
.addClass("text")
)
;
Update: I thought I'd update this post since it still gets quite a bit of traffic. In the comments below there's some discussion about $("<div>")
vs $("<div></div>")
vs $(document.createElement('div'))
as a way of creating new elements, and which is "best".
I put together a small benchmark, and here are roughly the results of repeating the above options 100,000 times:
jQuery 1.4, 1.5, 1.6
Chrome 11 Firefox 4 IE9
<div> 440ms 640ms 460ms
<div></div> 420ms 650ms 480ms
createElement 100ms 180ms 300ms
jQuery 1.3
Chrome 11
<div> 770ms
<div></div> 3800ms
createElement 100ms
jQuery 1.2
Chrome 11
<div> 3500ms
<div></div> 3500ms
createElement 100ms
I think it's no big surprise, but document.createElement
is the fastest method. Of course, before you go off and start refactoring your entire codebase, remember that the differences we're talking about here (in all but the archaic versions of jQuery) equate to about an extra 3 milliseconds per thousand elements.
Update 2
Updated for jQuery 1.7.2 and put the benchmark on JSBen.ch
which is probably a bit more scientific than my primitive benchmarks, plus it can be crowdsourced now!
Use:
SELECT DATE_FORMAT(NAME_COLUMN, "%d/%l/%Y") AS 'NAME'
SELECT DATE_FORMAT(NAME_COLUMN, "%d/%l/%Y %H:%i:%s") AS 'NAME'

If someone else have got a similar error message, you probably built the app with optimisations(production) flag on and that's why the error message is not that communicative. Another possibility that you have got the error under development (from i386 I know you were using simulator). If that is the case, change the build environment to development and try to reproduce the situation to get a more specific error message.
Its Shift + Alt + 2 to split into 2 screens. More options are found under the menu item View -> Layout.
Once the screen is split, you can open files using the shortcuts:
1. Ctrl + P (From existing directories within sublime) or
2. Ctrl + O(Browse directory)
Your problem is that you're not closing your HEREDOC correctly. The line containing END;
must not contain any whitespace afterwards.
This is not possible (as @JaredPar already mentioned). Trying to put logic to work around this is a bad practice. In case you have a base class
that have an enum
, you should list of all possible enum-values
there, and the implementation of class should work with the values that it knows.
E.g. Supposed you have a base class BaseCatalog
, and it has an enum ProductFormats
(Digital
, Physical
). Then you can have a MusicCatalog
or BookCatalog
that could contains both Digital
and Physical
products, But if the class is ClothingCatalog
, it should only contains Physical
products.

Well, since you asked for R equivalent to other languages, I tried to do this. Seems to work though I haven't really looked at which technique is more efficient in R.

For the categorical columns though, it would fetch you a Data Frame which you could typecast using as.character() if needed.
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
You can copy all contents of myhtml
to String
as follows:
Scanner myScanner = null;
try
{
myScanner = new Scanner(myhtml);
String contents = myScanner.useDelimiter("\\Z").next();
}
finally
{
if(myScanner != null)
{
myScanner.close();
}
}
Ofcourse, you can add a catch
block to handle exceptions properly.
Usually we have the need to control the width of the dropdown menu; specially that's essential when the dropdown menu holds a form, e.g. login form --- then the dropdown menu and its items should be wide enough for ease of inputing username/email and password.
Besides, when the screen is smaller than 768px or when the window (containing the dropdown menu) is zoomed down to smaller than 768px, Bootstrap 3 responsively scales the dropdown menu to the whole width of the screen/window. We need to keep this reponsive action.
Hence, the following css class could do that:
@media (min-width: 768px) {
.dropdown-menu {
width: 300px !important; /* change the number to whatever that you need */
}
}
(I had used it in my web app.)

I had the same problem.. It helped me, I'm specify the same field names of my classes as the tag names in the xml file (the file comes from an external system).
For example:
My xml file:
<Response>
<ESList>
<Item>
<ID>1</ID>
<Name>Some name 1</Name>
<Code>Some code</Code>
<Url>Some Url</Url>
<RegionList>
<Item>
<ID>2</ID>
<Name>Some name 2</Name>
</Item>
</RegionList>
</Item>
</ESList>
</Response>
My Response class:
@XmlRootElement(name="Response")
@XmlAccessorType(XmlAccessType.FIELD)
public class Response {
@XmlElement
private ESList[] ESList = new ESList[1]; // as the tag name in the xml file..
// getter and setter here
}
My ESList class:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name="ESList")
public class ESList {
@XmlElement
private Item[] Item = new Item[1]; // as the tag name in the xml file..
// getters and setters here
}
My Item class:
@XmlRootElement(name="Item")
@XmlAccessorType(XmlAccessType.FIELD)
public class Item {
@XmlElement
private String ID; // as the tag name in the xml file..
@XmlElement
private String Name; // and so on...
@XmlElement
private String Code;
@XmlElement
private String Url;
@XmlElement
private RegionList[] RegionList = new RegionList[1];
// getters and setters here
}
My RegionList class:
@XmlRootElement(name="RegionList")
@XmlAccessorType(XmlAccessType.FIELD)
public class RegionList {
Item[] Item = new Item[1];
// getters and setters here
}
My DemoUnmarshalling class:
public class DemoUnmarshalling {
public static void main(String[] args) {
try {
File file = new File("...");
JAXBContext jaxbContext = JAXBContext.newInstance(Response.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
jaxbUnmarshaller.setEventHandler(
new ValidationEventHandler() {
public boolean handleEvent(ValidationEvent event ) {
throw new RuntimeException(event.getMessage(),
event.getLinkedException());
}
}
);
Response response = (Response) jaxbUnmarshaller.unmarshal(file);
ESList[] esList = response.getESList();
Item[] item = esList[0].getItem();
RegionList[] regionLists = item[0].getRegionList();
Item[] regionListItem = regionLists[0].getItem();
System.out.println(item[0].getID());
System.out.println(item[0].getName());
System.out.println(item[0].getCode());
System.out.println(item[0].getUrl());
System.out.println(regionListItem[0].getID());
System.out.println(regionListItem[0].getName());
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
It gives:
1
Some name 1
Some code
Some Url
2
Some name 2

A funny way to remove all spaces from a variable is to use printf:
$ myvar='a cool variable with lots of spaces in it'
$ printf -v myvar '%s' $myvar
$ echo "$myvar"
acoolvariablewithlotsofspacesinit
It turns out it's slightly more efficient than myvar="${myvar// /}"
, but not safe regarding globs (*
) that can appear in the string. So don't use it in production code.
If you really really want to use this method and are really worried about the globbing thing (and you really should), you can use set -f
(which disables globbing altogether):
$ ls
file1 file2
$ myvar=' a cool variable with spaces and oh! no! there is a glob * in it'
$ echo "$myvar"
a cool variable with spaces and oh! no! there is a glob * in it
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglobfile1file2init
$ # See the trouble? Let's fix it with set -f:
$ set -f
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglob*init
$ # Since we like globbing, we unset the f option:
$ set +f
I posted this answer just because it's funny, not to use it in practice.

In Matplotlib lexicon, i think you want a hexbin plot.
If you're not familiar with this type of plot, it's just a bivariate histogram in which the xy-plane is tessellated by a regular grid of hexagons.
So from a histogram, you can just count the number of points falling in each hexagon, discretiize the plotting region as a set of windows, assign each point to one of these windows; finally, map the windows onto a color array, and you've got a hexbin diagram.
Though less commonly used than e.g., circles, or squares, that hexagons are a better choice for the geometry of the binning container is intuitive:
hexagons have nearest-neighbor symmetry (e.g., square bins don't, e.g., the distance from a point on a square's border to a point inside that square is not everywhere equal) and
hexagon is the highest n-polygon that gives regular plane tessellation (i.e., you can safely re-model your kitchen floor with hexagonal-shaped tiles because you won't have any void space between the tiles when you are finished--not true for all other higher-n, n >= 7, polygons).
(Matplotlib uses the term hexbin plot; so do (AFAIK) all of the plotting libraries for R; still i don't know if this is the generally accepted term for plots of this type, though i suspect it's likely given that hexbin is short for hexagonal binning, which is describes the essential step in preparing the data for display.)

Do I need to make another view which holds these 2 views?
Isn't there another way such as (without the BigViewModel):
Yes, you can use Tuple (brings magic in view having multiple model).
Code:
@model Tuple<LoginViewModel, RegisterViewModel>
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
@Html.TextBoxFor(tuple=> tuple.Item.Name)
@Html.TextBoxFor(tuple=> tuple.Item.Email)
@Html.PasswordFor(tuple=> tuple.Item.Password)
}
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
@Html.TextBoxFor(tuple=> tuple.Item1.Email)
@Html.PasswordFor(tuple=> tuple.Item1.Password)
}
It seems you are connecting to the wrong database. R u sure "jdbc:postgresql://localhost/testDB"
will connect you to the actual datasource ?
Generally they are of the form "jdbc://hostname/databasename".

Port 8080 might have been used by another process in your computer.
Do netstat

If you are using multiple platforms you are safer using this method.

You can escape the calc
arguments in order to prevent them from being evaluated on compilation.
Using your example, you would simply surround the arguments, like this:
calc(~'100% - 10px')
Demo : http://jsfiddle.net/c5aq20b6/
I find that I use this in one of the following three ways:
Everything inside the calc
arguments is defined as a string, and is totally static until it's evaluated by the client:
div {
> span {
width: calc(~'100% - 10px');
}
}
div > span {
width: calc(100% - 10px);
}
You can insert a LESS variable into the string:
div {
> span {
@pad: 10px;
width: calc(~'100% - @{pad}');
}
}
div > span {
width: calc(100% - 10px);
}
You may want to escape a percentage value, but go ahead and evaluate something on compilation:
@btnWidth: 40px;
div {
> span {
@pad: 10px;
width: calc(~'(100% - @{pad})' - (@btnWidth * 2));
}
}
div > span {
width: calc((100% - 10px) - 80px);
}

Install the extension "Code Runner". Check if you can compile your program with csc
(ex.: csc hello.cs
). The command csc
is shipped with Mono. Then add this to your VS Code user settings:
"code-runner.executorMap": {
"csharp": "echo '# calling mono\n' && cd $dir && csc /nologo $fileName && mono $dir$fileNameWithoutExt.exe",
// "csharp": "echo '# calling dotnet run\n' && dotnet run"
}
Open your C# file and use the execution key of Code Runner.
Edit: also added dotnet run
, so you can choose how you want to execute your program: with Mono, or with dotnet. If you choose dotnet, then first create the project (dotnet new console
, dotnet restore
).
Dockerfile
is good if you only have one docker file (per-directory). You can use whatever standard you want if you need multiple docker files in the same directory -
if you have a good reason. In a recent project there were AWS docker files and local dev environment files because the environments differed enough:

Try not to consider using a SPA without first defining how you will address security and API stability on the server side. Then you will see some of the true advantages to using a SPA. Specifically, if you use a RESTful server that implements OAUTH 2.0 for security, you will achieve two fundamental separation of concerns that can lower your development and maintenance costs.
Hinted to earlier, but not made explicit; If your goal is to deploy Android & Apple applications, writing a JavaScript SPA that is wrapped by a native call to host the screen in a browser (Android or Apple) eliminates the need to maintain both an Apple code base and an Android code base.
FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.
Some references:
Though you can use any other client that allows automation.
You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).
Combine WinSCP scripting capabilities with Windows Scheduler:
A typical WinSCP script for upload (with SFTP) looks like:
open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close
With FTP, just replace the sftp://
with the ftp://
and remove the -hostkey="..."
switch.
Similarly for download: How to schedule an automatic FTP download on Windows?
WinSCP can even generate a script from an imported FileZilla session.
For details, see the guide to FileZilla automation.
(I'm the author of WinSCP)
Another option, if you are using SFTP, is the psftp.exe
client from PuTTY suite.
As a side note, instead of having to type in the line numbers, just highlight the lines where you want to find/replace in one of the visual modes:
VISUAL
mode (V)VISUAL BLOCK
mode (Ctrl+V)VISUAL LINE
mode (Shift+V, works best in your case)Once you selected the lines to replace, type your command:
:s/<search_string>/<replace_string>/g
You'll note that the range '<,'>
will be inserted automatically for you:
:'<,'>s/<search_string>/<replace_string>/g
Here '<
simply means first highlighted line, and '>
means last highlighted line.
Note that the behaviour might be unexpected when in NORMAL
mode: '<
and '>
point to the start and end of the last highlight done in one of the VISUAL
modes. Instead, in NORMAL
mode, the special line number .
can be used, which simply means current line. Hence, you can find/replace only on the current line like this:
:.s/<search_string>/<replace_string>/g
Another thing to note is that inserting a second :
between the range and the find/replace command does no harm, in other words, these commands will still work:
:'<,'>:s/<search_string>/<replace_string>/g
:.:s/<search_string>/<replace_string>/g
A robust way to check if an object is an array in javascript is detailed here:
Here are two functions from the xa.js framework which I attach to a utils = {}
‘container’. These should help you properly detect arrays.
var utils = {};
/**
* utils.isArray
*
* Best guess if object is an array.
*/
utils.isArray = function(obj) {
// do an instanceof check first
if (obj instanceof Array) {
return true;
}
// then check for obvious falses
if (typeof obj !== 'object') {
return false;
}
if (utils.type(obj) === 'array') {
return true;
}
return false;
};
/**
* utils.type
*
* Attempt to ascertain actual object type.
*/
utils.type = function(obj) {
if (obj === null || typeof obj === 'undefined') {
return String (obj);
}
return Object.prototype.toString.call(obj)
.replace(/\[object ([a-zA-Z]+)\]/, '$1').toLowerCase();
};
If you then want to check if an object is in an array, I would also include this code:
/**
* Adding hasOwnProperty method if needed.
*/
if (typeof Object.prototype.hasOwnProperty !== 'function') {
Object.prototype.hasOwnProperty = function (prop) {
var type = utils.type(this);
type = type.charAt(0).toUpperCase() + type.substr(1);
return this[prop] !== undefined
&& this[prop] !== window[type].prototype[prop];
};
}
And finally this in_array function:
function in_array (needle, haystack, strict) {
var key;
if (strict) {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] === needle) {
return true;
}
}
} else {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] == needle) {
return true;
}
}
}
return false;
}
git reset --hard 1258f0d0aae
But be careful, if the descendant commits between 1258f0d0aae
and HEAD
are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD
, checkout master
, and reset to the commit you want.
Also, be sure that you don't have uncommitted changes before a reset --hard
, they will be truly lost (no way to recover).
You can also achieve similar results by using 'query' and @:
eg:
df = pd.DataFrame({'A': [1, 2, 3], 'B': ['a', 'b', 'f']})
df = pd.DataFrame({'A' : [5,6,3,4], 'B' : [1,2,3, 5]})
list_of_values = [3,6]
result= df.query("A in @list_of_values")
result
A B
1 6 2
2 3 3
You can use curly braces to control the number of occurrences. For example, this means 0 to 10:
/^[a-z]{0,10}$/
The options are:
See the regular expression reference.
Your expression had a + after the closing curly brace, hence the error.
When a there are 2 columns for primary keys they make up a composite primary key therefore you have to make sure that in the table that is being referenced there are also 2 columns of the same data type.
along with these two variants, there is also jade.renderFile
which generates html that need not be passed to the client.
usage-
var jade = require('jade');
exports.getJson = getJson;
function getJson(req, res) {
var html = jade.renderFile('views/test.jade', {some:'json'});
res.send({message: 'i sent json'});
}
getJson()
is available as a route in app.js.
Remember using
myDiv.InnerHtml = "something";
will replace all HTML elements in myDIV. you need to append text to avoid that.In that this may help
myDiv.InnerHtml = "something" + myDiv.InnerText;
any html control in myDiv but not ASP html controls(as they are not rendered yet).
In my case, I didn't need to preserve the repo I was migrating from or preserve any previous history. I had a patch of the same branch, from a different remote
#Source directory
git remote rm origin
#Target directory
git remote add branch-name-from-old-repo ../source_directory
In those two steps, I was able to get the other repo's branch to appear in the same repo.
Finally, I set this branch (that I imported from the other repo) to follow the target repo's mainline (so I could diff them accurately)
git br --set-upstream-to=origin/mainline
Now it behaved as-if it was just another branch I had pushed against that same repo.
I got it working in ubuntu 16.04 by following steps.My php version was 7.0
sudo apt-get install php7.0-curl
sudo service apache2 restart
JMS (ActiveMQ is a JMS broker implementation) can be used as a mechanism to allow asynchronous request processing. You may wish to do this because the request take a long time to complete or because several parties may be interested in the actual request. Another reason for using it is to allow multiple clients (potentially written in different languages) to access information via JMS. ActiveMQ is a good example here because you can use the STOMP protocol to allow access from a C#/Java/Ruby client.
A real world example is that of a web application that is used to place an order for a particular customer. As part of placing that order (and storing it in a database) you may wish to carry a number of additional tasks:
To do this your application code would publish a message onto a JMS queue which includes an order id. One part of your application listening to the queue may respond to the event by taking the orderId, looking the order up in the database and then place that order with another third party system. Another part of your application may be responsible for taking the orderId and sending a confirmation email to the customer.
Environment.getExternalStorageDirectory().getAbsolutePath()
Gives you the full path the SDCard. You can then do normal File I/O operations using standard Java.
Here's a simple example for writing a file:
String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName = "myFile.txt";
// Not sure if the / is on the path or not
File f = new File(baseDir + File.separator + fileName);
f.write(...);
f.flush();
f.close();
Edit:
Oops - you wanted an example for reading ...
String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName = "myFile.txt";
// Not sure if the / is on the path or not
File f = new File(baseDir + File.Separator + fileName);
FileInputStream fiStream = new FileInputStream(f);
byte[] bytes;
// You might not get the whole file, lookup File I/O examples for Java
fiStream.read(bytes);
fiStream.close();
var mask = /^\d+$/;
if ( myString.exec(mask) ){
/* That's a number */
}
Try the following function implemented in Swift 3.0 and above
func delayWithSeconds(_ seconds: Double, completion: @escaping () -> ()) {
DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
completion()
}
}
Usage
delayWithSeconds(1) {
//Do something
}
This could be due to Android Studio version conflict of v3 and v4 especially when you import a project in android stdio v4 which was previously built in v3.
Here are the few things you need to do:
As Wingman said, Google App Engine is a great solution for your scenario.
You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android
And from this Google IO 2012 session: http://www.youtube.com/watch?v=NU_wNR_UUn4
There is no way to dynamically increase the heap programatically since the heap is allocated when the Java Virtual Machine is started.
However, you can use this command
java -Xmx1024M YourClass
to set the memory to 1024
or, you can set a min max
java -Xms256m -Xmx1024m YourClassNameHere
I had a similar question, but was actually looking for a different answer; I'm looking to create a custom event. For example instead of always saying this:
$('#myInput').keydown(function(ev) {
if (ev.which == 13) {
ev.preventDefault();
// Do some stuff that handles the enter key
}
});
I want to abbreviate it to this:
$('#myInput').enterKey(function() {
// Do some stuff that handles the enter key
});
trigger and bind don't tell the whole story - this is a JQuery plugin. http://docs.jquery.com/Plugins/Authoring
The "enterKey" function gets attached as a property to jQuery.fn - this is the code required:
(function($){
$('body').on('keydown', 'input', function(ev) {
if (ev.which == 13) {
var enterEv = $.extend({}, ev, { type: 'enterKey' });
return $(ev.target).trigger(enterEv);
}
});
$.fn.enterKey = function(selector, data, fn) {
return this.on('enterKey', selector, data, fn);
};
})(jQuery);
http://jsfiddle.net/b9chris/CkvuJ/4/
A nicety of the above is you can handle keyboard input gracefully on link listeners like:
$('a.button').on('click enterKey', function(ev) {
ev.preventDefault();
...
});
Edits: Updated to properly pass the right this
context to the handler, and to return any return value back from the handler to jQuery (for example in case you were looking to cancel the event and bubbling). Updated to pass a proper jQuery event object to handlers, including key code and ability to cancel event.
Old jsfiddle: http://jsfiddle.net/b9chris/VwEb9/24/
You need to use the command pscp and forcing it to pass through sftp protocol. pscp is automatically installed when you install PuttY, a software to connect to a linux server through ssh.
When you have your pscp command here is the command line:
pscp -sftp -pw <yourPassword> "<pathToYourFile(s)>" <username>@<serverIP>:<PathInTheServerFromTheHomeDirectory>
These parameters (-sftp and -pw) are only available with pscp and not scp. You can also add -r if you want to upload everything in a folder in a recursive way.
While answers that refer to @ModelAttribute
, @RequestParam
, @PathParam
and the likes are valid, there is a small gotcha I ran into. The resulting method parameter is a proxy that Spring wraps around your DTO. So, if you attempt to use it in a context that requires your own custom type, you may get some unexpected results.
The following will not work:
@GetMapping(produces = APPLICATION_JSON_VALUE)
public ResponseEntity<CustomDto> request(@ModelAttribute CustomDto dto) {
return ResponseEntity.ok(dto);
}
In my case, attempting to use it in Jackson binding resulted in a com.fasterxml.jackson.databind.exc.InvalidDefinitionException
.
You will need to create a new object from the dto.
DEFAULT
is the value that will be inserted in the absence of an explicit value in an insert / update statement. Lets assume, your DDL did not have the NOT NULL
constraint:
ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT 'MyDefault'
Then you could issue these statements
-- 1. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B) VALUES (NULL, NULL);
-- 2. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B, col) VALUES (NULL, NULL, DEFAULT);
-- 3. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B, col) DEFAULT VALUES;
-- 4. This will insert NULL into tbl.col
INSERT INTO tbl (A, B, col) VALUES (NULL, NULL, NULL);
Alternatively, you can also use DEFAULT
in UPDATE
statements, according to the SQL-1992 standard:
-- 5. This will update 'MyDefault' into tbl.col
UPDATE tbl SET col = DEFAULT;
-- 6. This will update NULL into tbl.col
UPDATE tbl SET col = NULL;
Note, not all databases support all of these SQL standard syntaxes. Adding the NOT NULL
constraint will cause an error with statements 4, 6
, while 1-3, 5
are still valid statements. So to answer your question: No, they're not redundant.
If you are using Python3.
then you can use Print Function :
your_data = {"Purchase Amount": 'TotalAmount'}
print(your_data, file=open('D:\log.txt', 'w'))
For python2
this is the example of Python Print String To Text File
def my_func():
"""
this function return some value
:return:
"""
return 25.256
def write_file(data):
"""
this function write data to file
:param data:
:return:
"""
file_name = r'D:\log.txt'
with open(file_name, 'w') as x_file:
x_file.write('{} TotalAmount'.format(data))
def run():
data = my_func()
write_file(data)
run()
You can do this by adding them to the locals object in a general middleware.
app.use(function (req, res, next) {
res.locals = {
siteTitle: "My Website's Title",
pageTitle: "The Home Page",
author: "Cory Gross",
description: "My app's description",
};
next();
});
Locals is also a function which will extend the locals object rather than overwriting it. So the following works as well
res.locals({
siteTitle: "My Website's Title",
pageTitle: "The Home Page",
author: "Cory Gross",
description: "My app's description",
});
Full example
var app = express();
var middleware = {
render: function (view) {
return function (req, res, next) {
res.render(view);
}
},
globalLocals: function (req, res, next) {
res.locals({
siteTitle: "My Website's Title",
pageTitle: "The Root Splash Page",
author: "Cory Gross",
description: "My app's description",
});
next();
},
index: function (req, res, next) {
res.locals({
indexSpecificData: someData
});
next();
}
};
app.use(middleware.globalLocals);
app.get('/', middleware.index, middleware.render('home'));
app.get('/products', middleware.products, middleware.render('products'));
I also added a generic render middleware. This way you don't have to add res.render to each route which means you have better code reuse. Once you go down the reusable middleware route you'll notice you will have lots of building blocks which will speed up development tremendously.
Remember Running Background, Running continuously are two different tasks.
For long-term background processes, Threads aren't optimal with Android. However, here's the code and do it at your own risk...
Remember Service or Thread will run in the background but our task needs to make trigger (call again and again) to get updates, i.e. once the task is completed we need to recall the function for next update.
Timer (periodic trigger), Alarm (Timebase trigger), Broadcast (Event base Trigger), recursion will awake our functions.
public static boolean isRecursionEnable = true;
void runInBackground() {
if (!isRecursionEnable)
// Handle not to start multiple parallel threads
return;
// isRecursionEnable = false; when u want to stop
// on exception on thread make it true again
new Thread(new Runnable() {
@Override
public void run() {
// DO your work here
// get the data
if (activity_is_not_in_background) {
runOnUiThread(new Runnable() {
@Override
public void run() {
// update UI
runInBackground();
}
});
} else {
runInBackground();
}
}
}).start();
}
Using Service: If you launch a Service it will start, It will execute the task, and it will terminate itself. after the task execution. terminated might also be caused by exception, or user killed it manually from settings. START_STICKY (Sticky Service) is the option given by android that service will restart itself if service terminated.
Remember the question difference between multiprocessing and multithreading? Service is a background process (Just like activity without UI), The same way how you launch thread in the activity to avoid load on the main thread (Activity thread), the same way you need to launch threads(or async tasks) on service to avoid load on service.
In a single statement, if you want a run a background continues task, you need to launch a StickyService and run the thread in the service on event base
Escape sequences must be interpreted by SOMETHING to be converted to color. The standard CMD.EXE used by java when started from the command line, doesn't support this so therefore Java does not.
I'm not a 100% sure, but won't
$(data)
produce a jquery object with a DOM for that data, not connected anywhere? Or if it's already parsed as a DOM, you could just go $("#myImg", data), or whatever selector suits your needs.
EDIT
Rereading your question it appears your 'data' is already a DOM, which means you could just go (assuming there's only an img in your DOM, otherwise you'll need a more precise selector)
$("img", data).attr ("src")
if you want to access the src-attribute. If your data is just text, it would probably work to do
$("img", $(data)).attr ("src")
I'm not sure I understand your question. I assume you are doing something along the lines of:
import base64
with open("yourfile.ext", "rb") as image_file:
encoded_string = base64.b64encode(image_file.read())
You have to open the file first of course, and read its contents - you cannot simply pass the path to the encode function.
Edit: Ok, here is an update after you have edited your original question.
First of all, remember to use raw strings (prefix the string with 'r') when using path delimiters on Windows, to prevent accidentally hitting an escape character. Second, PIL's Image.open either accepts a filename, or a file-like (that is, the object has to provide read, seek and tell methods).
That being said, you can use cStringIO to create such an object from a memory buffer:
import cStringIO
import PIL.Image
# assume data contains your decoded image
file_like = cStringIO.StringIO(data)
img = PIL.Image.open(file_like)
img.show()
You can also do: mydate.toLocaleDateString();
More recent and much cleaner: use event.key
. No more arbitrary number codes!
NOTE: The old properties (
.keyCode
and.which
) are Deprecated.
const node = document.getElementsByClassName("input")[0];
node.addEventListener("keyup", function(event) {
if (event.key === "Enter") {
// Do work
}
});
Modern style, with lambda and destructuring
node.addEventListener('keyup', ({key}) => {
if (key === "Enter") return false
})
If you must use jQuery:
$(document).keyup(function(event) {
if ($(".input1").is(":focus") && event.key == "Enter") {
// Do work
}
});

The method you are trying to use checks if the button is active:
btnAdd.isEnabled()
When enabled, any component associated with this object is active and able to fire this object's actionPerformed method.
This method does not check if the button is pressed.
If i understand your question correctly, you want to disable your "Add" button after the user clicks "Check out".
Try disabling your button at start: btnAdd.setEnabled(false)
or after the user presses "Check out"
Though it is too late, I have found a better solution (that works for me) that will replace all consecutive same type white spaces with one white space of its type. That is:
Hello!\n\n\nMy World
will be
Hello!\nMy World
Notice there are still leading and trailing white spaces. So my complete solution is:
str = str.trim().replaceAll("(\\s)+", "$1"));
Here, trim()
replaces all leading and trailing white space strings with "". (\\s)
is for capturing \\s
(that is white spaces such as ' ', '\n', '\t') in group #1. +
sign is for matching 1 or more preceding token. So (\\s)+
can be consecutive characters (1 or more) among any single white space characters (' ', '\n' or '\t'). $1
is for replacing the matching strings with the group #1 string (which only contains 1 white space character) of the matching type (that is the single white space character which has matched). The above solution will change like this:
Hello!\n\n\nMy World
will be
Hello!\nMy World
I have not found my above solution here so I have posted it.

Typically, you would use a hash table and function object, both available in Boost, TR1 and C++0x.
void func1() {
}
std::unordered_map<std::string, std::function<void()>> hash_map;
hash_map["Value1"] = &func1;
// .... etc
hash_map[mystring]();
This is a little more overhead at runtime but a bajillion times more maintainable. Hash tables offer O(1) insertion, lookup, and etc, which makes them the same complexity as the assembly-style jump-table.
java.util.Date class has before and after method to compare dates.
Date date1 = new Date();
Date date2 = new Date();
if(date1.before(date2)){
//Do Something
}
if(date1.after(date2)){
//Do Something else
}
If you give your table a unique id, its easier:
<div id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a"
onmouseup="checkMultipleSelection(this,event);">
<table id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table"

</tr>

var multiselect =
document.getElementById(
'ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table'

timeXaddr = [multiselect[0].innerHTML, multiselect[2].innerHTML];
//=> timeXaddr now an array containing ['09:15 AM', 'Address1'];
A duplicate in the database should be a 409 CONFLICT

There is a way to do this without installing putty on your Mac. You can easily convert your existing PPK file to a PEM file using PuTTYgen on Windows.
Launch PuTTYgen and then load the existing private key file using the Load button. From the "Conversions" menu select "Export OpenSSH key" and save the private key file with the .pem file extension.
Copy the PEM file to your Mac and set it to be read-only by your user:
chmod 400 <private-key-filename>.pem
Then you should be able to use ssh to connect to your remote server
ssh -i <private-key-filename>.pem username@hostname
From where did you get the idea that you need to free(token)
and free(tk)
? You don't. strsep()
doesn't allocate memory, it only returns pointers inside the original string. Of course, those are not pointers allocated by malloc()
(or similar), so free()
ing them is undefined behavior. You only need to free(s)
when you are done with the entire string.
Also note that you don't need dynamic memory allocation at all in your example. You can avoid strdup()
and free()
altogether by simply writing char *s = p;
.
Since it is not yet supported using angular CLI
so here is the possible way, before that please observe what happens when you create a component/service using CLI (ex. ng g c demoComponent
).
demoComponent
(ng g c demoComponent
).HTML,CSS,ts
and a spec
file dedicated to demoComponent.so do it in reverse order
app.module.ts
when removing the dependency you have to do two things.
Order of iterators may seem counter-intuitive.
Take for example: [str(x) for i in range(3) for x in foo(i)]
Let's decompose it:
def foo(i):
return i, i + 0.5
[str(x)
for i in range(3)
for x in foo(i)
]
# is same as
for i in range(3):
for x in foo(i):
yield str(x)

C:\Users\Simion\AppData\Roaming\Sublime Text 2\Packages\Color Scheme - Default
Find your color scheme file, open it, and find lineHighlight
.
Ex:
<key>lineHighlight</key>
<string>#ccc</string>
replace #ccc
with your preferred background color.
The problem is described (among other) in this article.
#box
is relatively positioned, which makes it part of the "flow" of the page. Your other divs are absolutely positioned, so they are removed from the page's "flow".
Page flow means that the positioning of an element effects other elements in the flow.
In other words, as #box
now sees the dom, .a and .b are no longer "inside" #box
.
To fix this, you would want to make everything relative, or everything absolute.
One way would be:
.a {
position:relative;
margin-top:10px;
margin-left:10px;
background-color:red;
width:210px;
padding: 5px;
}

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests
If 'requests' is a json file then you have to change this to
$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests.json
Now before this, if your json file is not indexed, you have to insert an index line before each line inside the json file. You can do this with JQ. Refer below link: http://kevinmarsh.com/2014/10/23/using-jq-to-import-json-into-elasticsearch.html
Go to elasticsearch tutorials (example the shakespeare tutorial) and download the json file sample used and have a look at it. In front of each json object (each individual line) there is an index line. This is what you are looking for after using the jq command. This format is mandatory to use the bulk API, plain json files wont work.
Let's not forget math.hypot:
dist = math.hypot(x2-x1, y2-y1)
Here's hypot as part of a snippet to compute the length of a path defined by a list of (x, y) tuples:
from math import hypot
pts = [
(10,10),
(10,11),
(20,11),
(20,10),
(10,10),
]
# Py2 syntax - no longer allowed in Py3
# ptdiff = lambda (p1,p2): (p1[0]-p2[0], p1[1]-p2[1])
ptdiff = lambda p1, p2: (p1[0]-p2[0], p1[1]-p2[1])
diffs = (ptdiff(p1, p2) for p1, p2 in zip (pts, pts[1:]))
path = sum(hypot(*d) for d in diffs)
print(path)
Since 0.17, you have to use the explicit conversions:
pd.to_datetime, pd.to_timedelta and pd.to_numeric
(As mentioned below, no more "magic", convert_objects
has been deprecated in 0.17)
df = pd.DataFrame({'x': {0: 'a', 1: 'b'}, 'y': {0: '1', 1: '2'}, 'z': {0: '2018-05-01', 1: '2018-05-02'}})
df.dtypes
x object
y object
z object
dtype: object
df
x y z
0 a 1 2018-05-01
1 b 2 2018-05-02
You can apply these to each column you want to convert:
df["y"] = pd.to_numeric(df["y"])
df["z"] = pd.to_datetime(df["z"])
df
x y z
0 a 1 2018-05-01
1 b 2 2018-05-02
df.dtypes
x object
y int64
z datetime64[ns]
dtype: object
and confirm the dtype is updated.
OLD/DEPRECATED ANSWER for pandas 0.12 - 0.16: You can use convert_objects
to infer better dtypes:
In [21]: df
Out[21]:
x y
0 a 1
1 b 2
In [22]: df.dtypes
Out[22]:
x object
y object
dtype: object
In [23]: df.convert_objects(convert_numeric=True)
Out[23]:
x y
0 a 1
1 b 2
In [24]: df.convert_objects(convert_numeric=True).dtypes
Out[24]:
x object
y int64
dtype: object
Magic! (Sad to see it deprecated.)
First of all, from __future__ import print_function
needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print
as a function now. That's the whole point of from __future__ import print_function
; to bring the print
function from Python 3 into Python 2.6+.
from __future__ import print_function
import sys, os, time
for x in range(0,10):
print(x, sep=' ', end='') # No need for sep here, but okay :)
time.sleep(1)
__future__
statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:
A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.
The documentation also mentions that the only things that can precede a __future__
statement are the module docstring, comments, blank lines, and other future statements.
Before you can commit and push, you need to init a working repository tree for a submodule. I am using tortoise and do following things:
First check if there exist .git file (not a directory)
If there was .git file, there surly was .git directory which tracks local tree. You still need to a branch (you can create one) or switch to master (which sometimes does not work). Best to do is - git fetch - git pull. Do not omit fetch.
Now your commits and pulls will be synchronized with your origin/master
I did this.
class Circle
{
constuctor(radius)
{
this.radius = radius;
}
static get PI()
{
return 3.14159;
}
}
The value of PI is protected from being changed since it is a value being returned from a function. You can access it via Circle.PI. Any attempt to assign to it is simply dropped on the floor in a manner similar to an attempt to assign to a string character via [].
Simple but yet fast:
>>> def is_odd(a):
... return bool(a - ((a>>1)<<1))
...
>>> print(is_odd(13))
True
>>> print(is_odd(12))
False
>>>
Or even simpler:
>>> def is_odd(a):
... return bool(a & 1)
you can use get_result()
on the statement.
The best solution for me was to add a key binding to run PHP code directly in the terminal
To do so you just need to download terminal-command-keys
from VS code extensions marketplace:
Then got to File>Preferences>Keyboard Shortcuts and click on the following icon at the upper right corner:
It will open up the keybindings.json
file
Add the following settings
[
{
"key": "ctrl+s",
"command":"terminalCommandKeys.run",
"when": "editorLangId == php",
"args": {
"cmd":"php ${file}",
"newTerminal":true,
"saveAllfiles": true,
"showTerminal": true,
}
}
]
key is the shortcut to run your PHP file (I use ctrl+s) you can change it as you wish
when to run different commands for different file types (I set it for PHP files only) vscode's "when" clauses
See the full settings documentation from here
That's it, I hope it helps.
Make sure docker is running in your local machine. build command will work but its required running docker to get network data.
I think it will help.
Use a return statement!
return;
or
if (condition) return;
You don't need to (and can't) specify any values, if your method returns void
.
Another solution is to use the query method:
import pandas as pd
from random import randint
df = pd.DataFrame({'A': [randint(1, 9) for x in xrange(10)],
'B': [randint(1, 9) * 10 for x in xrange(10)],
'C': [randint(1, 9) * 100 for x in xrange(10)]})
print df
A B C
0 7 20 300
1 7 80 700
2 4 90 100
3 4 30 900
4 7 80 200
5 7 60 800
6 3 80 900
7 9 40 100
8 6 40 100
9 3 10 600
print df.query('B > 50 and C != 900')
A B C
1 7 80 700
2 4 90 100
4 7 80 200
5 7 60 800
Now if you want to change the returned values in column A you can save their index:
my_query_index = df.query('B > 50 & C != 900').index
....and use .iloc
to change them i.e:
df.iloc[my_query_index, 0] = 5000
print df
A B C
0 7 20 300
1 5000 80 700
2 5000 90 100
3 4 30 900
4 5000 80 200
5 5000 60 800
6 3 80 900
7 9 40 100
8 6 40 100
9 3 10 600
Use array_name.pop(index_no.)
ex:-
>>> arr = [1,2,3,4]
>>> arr.pop(2)
>>>arr
[1,2,4]
>>> arr1 = ['python3.6' , 'python2' ,'python3']
>>> arr1.remove('python2')
>>> arr1
['python3.6','python3']

I think you've missed the point of access control.
A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.
Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee
) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.
In your specific case, it seems that paste.ee
doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).
You must to have installed php_openssl.dll, if you use wampserver it's pretty easy, search and apply the extension for PHP.
In the example change this:
//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission 465 ssl
$mail->Port = 465;
//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'ssl';
and then you recived an email from gmail talking about to enable the option to Less Safe Access Applications here https://www.google.com/settings/security/lesssecureapps
I recommend you change the password and encrypt it constantly

I would like to avoid using full python directory path in the Notepad++ macro. I tried other solutions given in this page, they failed.
The one working on my PC is:
In Notepad++, press F5.
Copy/paste this:
cmd /k cd /d $(CURRENT_DIRECTORY) && py -3 -i $(FULL_CURRENT_PATH)
Enter.
I came across this, tot it would be nice to share...
What do you guys think?
$(document).ready(function() {
window.mousemove = function(e) {
p = $(e).position(); //remember $(e) - could be any html tag also..
left = e.left; //retrieving the left position of the div...
top = e.top; //get the top position of the div...
}
});
and boom, there we have it..
This line causes the [unchecked] warning:
List<String> list = new LinkedList();
So, the question transforms: why [unchecked] warning is not suppressed automatically only for the case when new collection is created?
I think, it would be much more difficult task then adding <>
feature.
UPD: I also think that there would be a mess if it were legally to use raw types 'just for a few things'.
Probably the browser first downloaded the validade script and then jQuery. If the validade script be downloaded before loading jQuery you'll get an error. You can see this using a tool like firebug.
Try this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
function LoadValidade() {
var a = false;
try {
var teste = $('*');
if(teste == null)
throw 1;
} catch (e) {
a = true;
}
if (a){
setTimeout(LoadValidade, 300);
return;
}
var validadeScript = document.createElement("script");
validadeScript.src = "../common/jquery.validate.js";
$('head')[0].appendChild(validadeScript);
}
setTimeout(LoadValidade, 300);
</script>
The rubocop gem contributors propose in their Ruby Style Guide:
Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.
class Westerner
def first_name
@names.first
end
alias given_name first_name
end
Always use alias_method when aliasing methods of modules, classes, or singleton classes at runtime, as the lexical scope of alias leads to unpredictability in these cases
module Mononymous
def self.included(other)
other.class_eval { alias_method :full_name, :given_name }
end
end
class Sting < Westerner
include Mononymous
end
This will work although when embedding PHP in HTML it is better practice to use the following form:
<table>
<?php foreach($array as $key=>$value): ?>
<tr>
<td><?= $key; ?></td>
</tr>
<?php endforeach; ?>
</table>
You can find the doc for the alternative syntax on PHP.net
If the issue is consistent and happened about 10-15 times in a row even after changing file permissions to 400 or 600, then it is most certainly something is wrong on the ec2 instance, so to make sure:
Check the logs when you try to ssh to the instance by adding -v at the end and see either it gives out anything specific.
Make sure you use the correct name for ssh, like Ubuntu. Perhaps that depends on Linux distribution and users you added and either you've given permission for "root user" ssh.
Then if nothing helps, follow the documentation here https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectingMindTerm to fix that. It helped in my case, and it happened because of messed up directories/files permissions.
It's enough to do:
data=`date`
datatime=`date -d "${data}" '+%Y%m%d'`
echo $datatime

If you want to add also the time you can use in that way
data=`date`
datatime=`date -d "${data}" '+%Y%m%d %T'`
echo $data

To use C# (C# Script was initialized at 2015) on ASPX page you can make use the following syntax.
Start Tag:- <%
End tag:- %>
Please make sure that all the C# code must reside inside this <%%>
.
Syntax Example:-
<%@ Import Namespace="System.Web.UI.WebControls" %>
(For importing Namespace)
Reference to some basic namespaces for working with ASPX page.
<%@ Import Namespace="System.Web.UI.WebControls" %>
<%@ Import Namespace="System.Diagnostics" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Web" %>
<%@ Import Namespace="System.Web.UI" %>
<%@ Import Namespace="System.IO" %>
C# Code:-
`<%
if (Session["New"] != null)
{
Page.Title = ActionController.GetName(Session["New"].ToString());
}
%>`
Features of C# Script:
Before using C# script make sure the following things:-
C# script can be inserted anywhere in the aspx page but after the page meta declaration like
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Profile.master.cs" Inherits="OOSDDemo.Profile" %>
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication3.WebForm1" %>
(For WebForm)

Promises can be "handled" after they are rejected. That is, one can call a promise's reject callback before providing a catch handler. This behavior is a little bothersome to me because one can write...
var promise = new Promise(function(resolve) {
kjjdjf(); // this function does not exist });
... and in this case, the Promise is rejected silently. If one forgets to add a catch handler, code will continue to silently run without errors. This could lead to lingering and hard-to-find bugs.
In the case of Node.js, there is talk of handling these unhandled Promise rejections and reporting the problems. This brings me to ES7 async/await. Consider this example:
async function getReadyForBed() {
let teethPromise = brushTeeth();
let tempPromise = getRoomTemperature();
// Change clothes based on room temperature
let temp = await tempPromise;
// Assume `changeClothes` also returns a Promise
if(temp > 20) {
await changeClothes("warm");
} else {
await changeClothes("cold");
}
await teethPromise;
}
In the example above, suppose teethPromise was rejected (Error: out of toothpaste!) before getRoomTemperature was fulfilled. In this case, there would be an unhandled Promise rejection until await teethPromise.
My point is this... if we consider unhandled Promise rejections to be a problem, Promises that are later handled by an await might get inadvertently reported as bugs. Then again, if we consider unhandled Promise rejections to not be problematic, legitimate bugs might not get reported.
Thoughts on this?
This is related to the discussion found in the Node.js project here:
Default Unhandled Rejection Detection Behavior
if you write the code this way:
function getReadyForBed() {
let teethPromise = brushTeeth();
let tempPromise = getRoomTemperature();
// Change clothes based on room temperature
return Promise.resolve(tempPromise)
.then(temp => {
// Assume `changeClothes` also returns a Promise
if (temp > 20) {
return Promise.resolve(changeClothes("warm"));
} else {
return Promise.resolve(changeClothes("cold"));
}
})
.then(teethPromise)
.then(Promise.resolve()); // since the async function returns nothing, ensure it's a resolved promise for `undefined`, unless it's previously rejected
}
When getReadyForBed is invoked, it will synchronously create the final (not returned) promise - which will have the same "unhandled rejection" error as any other promise (could be nothing, of course, depending on the engine). (I find it very odd your function doesn't return anything, which means your async function produces a promise for undefined.
If I make a Promise right now without a catch, and add one later, most "unhandled rejection error" implementations will actually retract the warning when i do later handle it. In other words, async/await doesn't alter the "unhandled rejection" discussion in any way that I can see.
to avoid this pitfall please write the code this way:
async function getReadyForBed() {
let teethPromise = brushTeeth();
let tempPromise = getRoomTemperature();
// Change clothes based on room temperature
var clothesPromise = tempPromise.then(function(temp) {
// Assume `changeClothes` also returns a Promise
if(temp > 20) {
return changeClothes("warm");
} else {
return changeClothes("cold");
}
});
/* Note that clothesPromise resolves to the result of `changeClothes`
due to Promise "chaining" magic. */
// Combine promises and await them both
await Promise.all(teethPromise, clothesPromise);
}
Note that this should prevent any unhandled promise rejection.
You're defining the same class twice is why.
If your intent is to implement the methods in the CPP file then do so something like this:
gameObject::gameObject()
{
x = 0;
y = 0;
}
gameObject::~gameObject()
{
//
}
int gameObject::add()
{
return x+y;
}
In my case, I had a sequence with the same name.
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.
I like Daniel Cerecedo's answer using toJSON()
and regex. An even simpler form would be:
var now = new Date();
var regex = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}).*$/;
var token_array = regex.exec(now.toJSON());
// [ "2017-10-31T02:24:45.868Z", "2017", "10", "31", "02", "24", "45" ]
var myFormat = token_array.slice(1).join('');
// "20171031022445"
The difference can be seen from below sample pyspark code:
rdd = sc.parallelize([2, 3, 4])
rdd.flatMap(lambda x: range(1, x)).collect()
Output:
[1, 1, 2, 1, 2, 3]
rdd.map(lambda x: range(1, x)).collect()
Output:
[[1], [1, 2], [1, 2, 3]]
Maybe because it's harder to steal a password from your brain then to steal a key file from your computer (at least to my knowledge, maybe some substances exist already or methods but this is an infinite discussion)? And if you password protect the key, then you are using a password again and the same problems arise (but some might argue that you have to do more work, because you need to get the key and then crack the password).
You can use $_SERVER['HTTP_REFERER']
this will give you whole URL for example:
suppose you want to get url of site name www.example.com
then $_SERVER['HTTP_REFERER']
will give you https://www.example.com

In simple words: You do abstraction when deciding what to implement. You do encapsulation when hiding something that you have implemented.
Since the advent of p2, you should be using the dropins directory instead.
To be completely clear create "plugins" under "/dropins" and make sure to restart eclipse with the "-clean" option.

I try to explain it more understandably than the referred PostgreSQL documentation.
Neither TIMESTAMP
variants store a time zone (or an offset), despite what the names suggest. The difference is in the interpretation of the stored data (and in the intended application), not in the storage format itself:
TIMESTAMP WITHOUT TIME ZONE
stores local date-time (aka. wall calendar date and wall clock time). Its time zone is unspecified as far as PostgreSQL can tell (though your application may knows what it is). Hence, PostgreSQL does no time zone related conversion on input or output. If the value was entered into the database as '2011-07-01 06:30:30'
, then no mater in what time zone you display it later, it will still say year 2011, month 07, day 01, 06 hours, 30 minutes, and 30 seconds (in some format). Also, any offset or time zone you specify in the input is ignored by PostgreSQL, so '2011-07-01 06:30:30+00'
and '2011-07-01 06:30:30+05'
are the same as just '2011-07-01 06:30:30'
.
For Java developers: it's analogous to java.time.LocalDateTime
.
TIMESTAMP WITH TIME ZONE
stores a point on the UTC time line. How it looks (how many hours, minutes, etc.) depends on your time zone, but it always refers to the same "physical" instant (like the moment of an actual physical event). The
input is internally converted to UTC, and that's how it's stored. For that, the offset of the input must be known, so when the input contains no explicit offset or time zone (like '2011-07-01 06:30:30'
) it's assumed to be in the current time zone of the PostgreSQL session, otherwise the explicitly specified offset or time zone is used (as in '2011-07-01 06:30:30+05'
). The output is displayed converted to the current time zone of the PostgreSQL session.
For Java developers: It's analogous to java.time.Instant
(with lower resolution though), but with JDBC and JPA 2.2 you are supposed to map it to java.time.OffsetDateTime
(or to java.util.Date
or java.sql.Timestamp
of course).
Some say that both TIMESTAMP
variations store UTC date-time. Kind of, but it's confusing to put it that way in my opinion. TIMESTAMP WITHOUT TIME ZONE
is stored like a TIMESTAMP WITH TIME ZONE
, which rendered with UTC time zone happens to give the same year, month, day, hours, minutes, seconds, and microseconds as they are in the local date-time. But it's not meant to represent the point on the time line that the UTC interpretation says, it's just the way the local date-time fields are encoded. (It's some cluster of dots on the time line, as the real time zone is not UTC; we don't know what it is.)
__func__
is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:
The identifier
__func__
is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declarationstatic const char __func__[] = "function-name";
appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function.
Note that it is not a macro and it has no special meaning during preprocessing.
__func__
was added to C++ in C++11, where it is specified as containing "an implementation-de?ned string" (C++11 §8.4.1[dcl.fct.def.general]/8), which is not quite as useful as the specification in C. (The original proposal to add __func__
to C++ was N1642).
__FUNCTION__
is a pre-standard extension that some C compilers support (including gcc and Visual C++); in general, you should use __func__
where it is supported and only use __FUNCTION__
if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__
).
__PRETTY_FUNCTION__
is a gcc extension that is mostly the same as __FUNCTION__
, except that for C++ functions it contains the "pretty" name of the function including the signature of the function. Visual C++ has a similar (but not quite identical) extension, __FUNCSIG__
.
For the nonstandard macros, you will want to consult your compiler's documentation. The Visual C++ extensions are included in the MSDN documentation of the C++ compiler's "Predefined Macros". The gcc documentation extensions are described in the gcc documentation page "Function Names as Strings."
ALTER TABLE YourTableNameHere ALTER COLUMN YourColumnNameHere VARCHAR(20)
None of the other answers worked for me, here is what eventually did.
I had to track the previous selected value of the select element and store it in the data-* attribute. Then I had to use the val() method for the select box that JQuery provides. Also, I had to make sure I was using the value attribute in my options when I populated the select box.
<body>
<select id="sel">
<option value="Apple">Apple</option> <!-- Must use the value attribute on the options in order for this to work. -->
<option value="Bannana">Bannana</option>
<option value="Cherry">Cherry</option>
</select>
</body>
<script src="https://code.jquery.com/jquery-3.5.1.js" type="text/javascript" language="javascript"></script>

$("#sel").on("click", sel_TrackLastChange);
$("#sel").on("keydown", sel_TrackLastChange);
$("#sel").on("change", sel_Change);
$("#sel").data("lastSelected", $("#sel").val());
}
//
// Track the previously selected value when the user either clicks on or uses the keyboard to change
// the option in the select box. Store it in the select box's data-* attribute.
function sel_TrackLastChange()
{
$("#sel").data("lastSelected", $("#sel").val());
}
//
// When the option changes on the select box, ask the user if they want to change it.
function sel_Change()
{
if(!confirm("Are you sure?"))
{
//
// If the user does not want to change the selection then use JQuery's .val() method to change
// the selection back to what it was previously.
$("#sel").val($("#sel").data("lastSelected"));
}
}
</script>
I hope this can help someone else who has the same problem as I did.

I know there is an approved answer already, but I kinda like this JSON approach.
npm start '{"PROJECT_NAME_STR":"my amazing stuff", "CRAZY_ARR":[0,7,"hungry"], "MAGICAL_NUMBER_INT": 42, "THING_BOO":true}';
Usually I have like 1 var I need, such as a project name, so I find this quick n' simple.
Also I often have something like this in my package.json
"scripts": {
"start": "NODE_ENV=development node local.js"
}
And being greedy I want "all of it", NODE_ENV and the CMD line arg stuff.
You simply access these things like so in your file (in my case local.js)
console.log(process.env.NODE_ENV, starter_obj.CRAZY_ARR, starter_obj.PROJECT_NAME_STR, starter_obj.MAGICAL_NUMBER_INT, starter_obj.THING_BOO);
You just need to have this bit above it (I'm running v10.16.0 btw)
var starter_obj = JSON.parse(JSON.parse(process.env.npm_config_argv).remain[0]);
Anyhoo, question already answered. Thought I'd share, as I use this method a lot.
You Can Too Do This:
Step 1)Convert Your Private Channel To Public Channel
Step 2)Set The ChannelName For This Channel
Step 3)then you Can change this Channel to Private
Step 4)Now Sending Your Message Using @ChannelName That you Set In Step 3
note:For Step 1 You Can Change One of Your Public Channel To Private For a short time.

This problem reported as issue (#582) on plugin's github, btw this solution mentioned there too, (https://github.com/kenwheeler/slick/issues/582)
I think this would be a more simpler way of outputting your results.
Sorry for using my own data should be easy to replace .
$query = "SELECT * FROM category ";
$result = mysqli_query($connection, $query);
while($row = mysqli_fetch_assoc($result))
{
$cat_id = $row['cat_id'];
$cat_title = $row['cat_title'];
echo $cat_id . " " . $cat_title ."<br>";
}
This would output :
Capture the onContextMenu
event, and return false in the event handler.
You can also capture the click event and check which mouse button fired the event with event.button
, in some browsers anyway.
I had the same error with Oracle.DataAccess
but deploying to Azure Web Sites (azurewebsites.net). For me I had to edit a setting in VS.NET 2019 before publishing to Azure. I ticked the checkbox "Use the 64 bit version of IIS Express for Web sites and projects" which is found under Tools > Options > Projects and Solutions > Web Projects

Numpy has a module for this. Just a small hack. Put your input array as bins.
numpy.histogram(y, bins=y)
The output are 2 arrays. One with the values itself, other with the corresponding frequencies.
you can set it in .bashrc
PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.
So, first build a list, then use pickle.dump
to send it to a file...

Looks like PostgreSQL supports a schema object called a rule.
http://www.postgresql.org/docs/current/static/rules-update.html
You could create a rule ON INSERT
for a given table, making it do NOTHING
if a row exists with the given primary key value, or else making it do an UPDATE
instead of the INSERT
if a row exists with the given primary key value.
I haven't tried this myself, so I can't speak from experience or offer an example.
A new option is Jexus Manager for IIS Express,

For anyone that's searching why their chrome debugger is automatically jumping to sources tab on every page load, event though all of the breakpoints/pauses/etc have been disabled.
For me it was the "breakOnLoad": true
line in VS Code launch.json
config.
You can put this inside your jquery code or it can stand alone:
window.onload = prep;
function prep(){
document.getElementById('somediv').onclick = function(){
document.getElementById('inputField').value ='';
}
}
Convert binary file to base64 & vice versa. Prove in python 3.5.2
import base64
read_file = open('/tmp/newgalax.png', 'rb')
data = read_file.read()
b64 = base64.b64encode(data)
print (b64)
# Save file
decode_b64 = base64.b64decode(b64)
out_file = open('/tmp/out_newgalax.png', 'wb')
out_file.write(decode_b64)
# Test in python 3.5.2
Since I have to reuse this few time, I came up with this class that simply help to abstract how the query string is composed.
public class UriBuilderExt
{
private NameValueCollection collection;
private UriBuilder builder;
public UriBuilderExt(string uri)
{
builder = new UriBuilder(uri);
collection = System.Web.HttpUtility.ParseQueryString(string.Empty);
}
public void AddParameter(string key, string value) {
collection.Add(key, value);
}
public Uri Uri{
get
{
builder.Query = collection.ToString();
return builder.Uri;
}
}
}
The use will be simplify to something like this:
var builder = new UriBuilderExt("http://example.com/");
builder.AddParameter("foo", "bar<>&-baz");
builder.AddParameter("bar", "second");
var uri = builder.Uri;
that will return the uri: http://example.com/?foo=bar%3c%3e%26-baz&bar=second
I've had a hard time with ssh2 in php mostly because the output stream sometimes works and sometimes it doesn't. I'm just gonna paste my lib here which works for me very well. If there are small inconsistencies in code it's because I have it plugged in a framework but you should be fine porting it:

Select your project properties from Project Tab Then Application->Resource->Icon And Manifest->change the default icon
This works in Visual studio 2019 finely Note:Only files with .ico format can be added as icon
function getMetaContentByName(name,content){
var content = (content==null)?'content':content;
return document.querySelector("meta[name='"+name+"']").getAttribute(content);
}
Used in this way:
getMetaContentByName("video");
The example on this page:
getMetaContentByName("twitter:domain");
You also may use an extension method, so it will be more readable (although everybody is already used to the regular Parse functions).
public static class StringExtensions
{
/// <summary>
/// Converts a string to int.
/// </summary>
/// <param name="value">The string to convert.</param>
/// <returns>The converted integer.</returns>
public static int ParseToInt32(this string value)
{
return int.Parse(value);
}
/// <summary>
/// Checks whether the value is integer.
/// </summary>
/// <param name="value">The string to check.</param>
/// <param name="result">The out int parameter.</param>
/// <returns>true if the value is an integer; otherwise, false.</returns>
public static bool TryParseToInt32(this string value, out int result)
{
return int.TryParse(value, out result);
}
}
And then you can call it that way:
If you are sure that your string is an integer, like "50".
int num = TextBoxD1.Text.ParseToInt32();
If you are not sure and want to prevent crashes.
int num;
if (TextBoxD1.Text.TryParseToInt32(out num))
{
//The parse was successful, the num has the parsed value.
}
To make it more dynamic, so you can parse it also to double, float, etc., you can make a generic extension.
In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).
For anyone checking this using python 3:
If you want to print the following output "100% correct"
:
python 3.8: print("100% correct")
python 3.7 and less: print("100%% correct")
A neat programming workaround for compatibility across diff versions of python is shown below:
Note: If you have to use this, you're probably experiencing many other errors... I'd encourage you to upgrade / downgrade python in relevant machines so that they are all compatible.
DevOps is a notable exception to the above -- implementing the following code would indeed be appropriate for specific DevOps / Debugging scenarios.
import sys
if version_info.major==3:
if version_info.minor>=8:
my_string = "100% correct"
else:
my_string = "100%% correct"
# Finally
print(my_string)
If you just want to apply a function to each element and put the results in an output array, you can use arrayfun
.
As others have pointed out, for most operations, it's best to avoid loops in MATLAB and vectorise your code instead.
Explicitly mention the ubuntu version in the docker file which you are trying to RUN,

I'm pretty late to the party, but I came up with this myself and it's one of my favorite quick hacks for vertical alignment. It's crazy simple, and easy to understand what's going on.
You use the :before
css attribute to insert a div into the beginning of the parent div, give it display:inline-block
and vertical-align:middle
and then give those same properties to the child div. Since vertical-align
is for alignment along a line, those inline divs will be considered a line.
Make the :before
div height:100%
, and the child div will automatically follow and align in the middle of a very tall "line."
.parent:before, .child {
display:inline-block;
vertical-align:middle;
}
.parent:before {
content:""; // so that it shows up
height:100%; // so it takes up the full height
}
Here's a fiddle to demonstrate what I'm talking about. The child div can be any height, and you never have to modify its margins/paddings.
And here's a more explanatory fiddle.
If you're not fond of :before
, you can always manually put in a div.
<div class="parent">
<div class="before"></div>
<div class="child">
content
</div>
</div>
And then just reassign .parent:before
to .parent .before
This typically stems from a bug in revision control system, or similar. This was a product from CVS, if a file was checked in from Windows to Unix server, and then checked out again...
In other words, it is just broken...
A good rule of thumb: use the built-in help system in Python. Example below...

The best way to find out is looking at the Execution Plan.
I tried it with Oracle, and it was exactly the same.
CREATE TABLE performance_test AS ( SELECT * FROM dba_objects );
SELECT * FROM performance_test
WHERE object_name IN ('DBMS_STANDARD', 'DBMS_REGISTRY', 'DBMS_LOB' );
Even though the query uses IN
, the Execution Plan says that it uses OR
:
--------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
--------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 8 | 1416 | 163 (2)| 00:00:02 |
|* 1 | TABLE ACCESS FULL| PERFORMANCE_TEST | 8 | 1416 | 163 (2)| 00:00:02 |
--------------------------------------------------------------------------------------
Predicate Information (identified by operation id):
---------------------------------------------------
1 - filter("OBJECT_NAME"='DBMS_LOB' OR "OBJECT_NAME"='DBMS_REGISTRY' OR
"OBJECT_NAME"='DBMS_STANDARD')
Mysql has this handy UPDATE INTO command ;)
edit Looks like they renamed it to REPLACE
REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted
I got a similar problem with sql server , I have tried every thing but does not connect to database engine & it shows error:26.
IF the database engine is not running, simply uninstall sql
server / format your system if possible and then download sql
server 2012 and management studio. from
https://www.microsoft.com/en-ca/download/details.aspx?id=29062
Install server first, make sure to add server on installation phase
by clicking add server and then install management studio.
multipart/form-data
Note. Please consult RFC2388 for additional information about file uploads, including backwards compatibility issues, the relationship between "multipart/form-data" and other content types, performance issues, etc.
Please consult the appendix for information about security issues for forms.
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
The content type "multipart/form-data" follows the rules of all multipart MIME data streams as outlined in RFC2045. The definition of "multipart/form-data" is available at the [IANA] registry.
A "multipart/form-data" message contains a series of parts, each representing a successful control. The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream. Part boundaries should not occur in any of the data; how this is done lies outside the scope of this specification.
As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows:
Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by
%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A').
The control names/values are listed in the order they appear in the document. The name is separated from the value by
=' and name/value pairs are separated from each other by `&'.
application/x-www-form-urlencoded
the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:
MyVariableOne=ValueOne&MyVariableTwo=ValueTwo
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
I accomplished this by calling/overriding viewWillDisappear
and then accessing the stack of the navigationController
like this:
override func viewWillDisappear(animated: Bool) {
super.viewWillDisappear(animated)
let stack = self.navigationController?.viewControllers.count
if stack >= 2 {
// for whatever reason, the last item on the stack is the TaskBuilderViewController (not self), so we only use -1 to access it
if let lastitem = self.navigationController?.viewControllers[stack! - 1] as? theViewControllerYoureTryingToAccess {
// hand over the data via public property or call a public method of theViewControllerYoureTryingToAccess, like
lastitem.emptyArray()
lastitem.value = 5
}
}
}

The syntax to disable an HTML input is as follows:
<input type="text" id="input_id" DISABLED />
For those who are a bit lazy, I recommend running this as a bat file for when ever you want to enable it:
reg add "HKLM\Software\Microsoft\Fusion" /v EnableLog /t REG_DWORD /d 1 /f
reg add "HKLM\Software\Microsoft\Fusion" /v ForceLog /t REG_DWORD /d 1 /f
reg add "HKLM\Software\Microsoft\Fusion" /v LogFailures /t REG_DWORD /d 1 /f
reg add "HKLM\Software\Microsoft\Fusion" /v LogResourceBinds /t REG_DWORD /d 1 /f
reg add "HKLM\Software\Microsoft\Fusion" /v LogPath /t REG_SZ /d C:\FusionLog\
if not exist "C:\FusionLog\" mkdir C:\FusionLog
Generally speaking, IN
and JOIN
are different queries that can yield different results.
SELECT a.*
FROM a
JOIN b
ON a.col = b.col
is not the same as
SELECT a.*
FROM a
WHERE col IN
(
SELECT col
FROM b
)
, unless b.col
is unique.
However, this is the synonym for the first query:
SELECT a.*
FROM a
JOIN (
SELECT DISTINCT col
FROM b
)
ON b.col = a.col
If the joining column is UNIQUE
and marked as such, both these queries yield the same plan in SQL Server
.
If it's not, then IN
is faster than JOIN
on DISTINCT
.
See this article in my blog for performance details:
Here is an example where the things to add come from a dictionary
>>> L = [0, 0, 0, 0]
>>> things_to_add = ({'idx':1, 'amount': 1}, {'idx': 2, 'amount': 1})
>>> for item in things_to_add:
... L[item['idx']] += item['amount']
...
>>> L
[0, 1, 1, 0]
Here is an example adding elements from another list
>>> L = [0, 0, 0, 0]
>>> things_to_add = [0, 1, 1, 0]
>>> for idx, amount in enumerate(things_to_add):
... L[idx] += amount
...
>>> L
[0, 1, 1, 0]
You could also achieve the above with a list comprehension and zip
L[:] = [sum(i) for i in zip(L, things_to_add)]
Here is an example adding from a list of tuples
>>> things_to_add = [(1, 1), (2, 1)]
>>> for idx, amount in things_to_add:
... L[idx] += amount
...
>>> L
[0, 1, 1, 0]
& 0xFF
by itself only ensures that if bytes are longer than 8 bits (allowed by the language standard), the rest are ignored.
And that seems to work fine too?
If the result ends up greater than SHRT_MAX
, you get undefined behavior. In that respect both will work equally poorly.
I was using eclipse and after trying all the other answers it didn't work for me.
In the end, what worked for me was moving the ojdb7.jar
to top in the Build Path. This occurs when multiple jars have conflicting same classes.
- Select project in
Project Explorer
- Right click on
Project -> Build Path -> Configure Build Path
- Go to
Order and Export
tab and selectojdbc.jar
- Click button
TOP
to move it to top
You can do the same in insider's edition, There is an option on right top corner to switch to the panel to sidebar https://code.visualstudio.com/insiders/
I have encountered this issue with play-services:5.0.89. Upgrading to 6.1.11 solved problem.
Open the Internet Explorer Developer Tool, Tools -> F12 developer tools. (I think you can also press F12 to get it)
Change the Document Mode to Standards. (The page should be automatically refresh, if you change the Document Mode)
Problem should be fixed. Enjoy
Another option is
if (myString?.trim()) {
...
}
this is a simple code I just wrote to solve this, without removing the header row (first one).
var Tbl = document.getElementById('tblId');
while(Tbl.childNodes.length>2){Tbl.removeChild(Tbl.lastChild);}
Hope it works for you!!.
Try this:
$Wsdl = 'http://xxxx.xxx.xx/webservice3.asmx?WSDL';
libxml_disable_entity_loader(false); //adding this worked for me
$Client = new SoapClient($Wsdl);
//Code...
I have a slightly simplified answer for this (with just the PreviewMouseLeftButtonDown
event) which seems to mimic the usual functionality of a browser:
In XAML you have a TextBox
say:
<TextBox Text="http://www.blabla.com" BorderThickness="2" BorderBrush="Green" VerticalAlignment="Center" Height="25"
PreviewMouseLeftButtonDown="SelectAll" />
In codebehind:
private void SelectAll(object sender, MouseButtonEventArgs e)
{
TextBox tb = (sender as TextBox);
if (tb == null)
{
return;
}
if (!tb.IsKeyboardFocusWithin)
{
tb.SelectAll();
e.Handled = true;
tb.Focus();
}
}
1) Go to (Open) Command Prompt (Press Window + R then type cmd Run this).
2) Run following commands
For all listening ports
Apply port filter
Finally with the PID we can run the following command to kill the process
3) Copy PID from result set
Ex: taskkill /F /PID 189
Done !!! you can start your service now.
Add a type to your variable and then return.
Eg:
const myVariable : string [] = ['hello', 'there'];
const result = myVaraible.map(x=> {
return
{
x.id
}
});
=> Important part is adding the string[] type etc:

rm ~/.yarnrc.yml
Simple Xpath for locating Google search box is: Xpath=//span[text()='Google Search']
Don't include header.php. You should not output HTML when you are going to redirect.
Make a new file, eg. "pre.php". Put this in it:
<?php
include('class.user.php');
include('class.Connection.php');
?>
Then in header.php, include that, in stead of including the two other files. In form.php, include pre.php in stead of header.php.
With the v3 API, you can easily close the InfoWindow
with the InfoWindow.close()
method. You simply need to keep a reference to the InfoWindow
object that you are using. Consider the following example, which opens up an InfoWindow
and closes it after 5 seconds:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps API InfoWindow Demo</title>
<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 400px; height: 500px;"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: new google.maps.LatLng(-25.36388, 131.04492),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map
});
var infowindow = new google.maps.InfoWindow({
content: 'An InfoWindow'
});
infowindow.open(map, marker);
setTimeout(function () { infowindow.close(); }, 5000);
</script>
</body>
</html>
If you have a separate InfoWindow
object for each Marker
, you may want to consider adding the InfoWindow
object as a property of your Marker
objects:
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map
});
marker.infowindow = new google.maps.InfoWindow({
content: 'An InfoWindow'
});
Then you would be able to open and close that InfoWindow
as follows:
marker.infowindow.open(map, marker);
marker.infowindow.close();
The same applies if you have an array of markers:
var markers = [];
marker[0] = new google.maps.Marker({
position: map.getCenter(),
map: map
});
marker[0].infowindow = new google.maps.InfoWindow({
content: 'An InfoWindow'
});
// ...
marker[0].infowindow.open(map, marker);
marker[0].infowindow.close();
