I am answering this old question just because it still shows up in google queries and I think one optimal answer is missing. Try this code: use ::before or ::after
Extend the DOM Element, Handle the Error, and Degrade Gracefully
Below I use the prototype function to wrap the native DOM play function, grab its promise, and then degrade to a play button if the browser throws an exception. This extension addresses the shortcoming of the browser and is plug-n-play in any page with knowledge of the target element(s).
// JavaScript
// Wrap the native DOM audio element play function and handle any autoplay errors
Audio.prototype.play = (function(play) {
return function () {
var audio = this,
args = arguments,
promise = play.apply(audio, args);
if (promise !== undefined) {
promise.catch(_ => {
// Autoplay was prevented. This is optional, but add a button to start playing.
var el = document.createElement("button");
el.innerHTML = "Play";
el.addEventListener("click", function(){play.apply(audio, args);});
this.parentNode.insertBefore(el, this.nextSibling)
});
}
};
})(Audio.prototype.play);
// Try automatically playing our audio via script. This would normally trigger and error.
document.getElementById('MyAudioElement').play()
<!-- HTML -->
<audio id="MyAudioElement" autoplay>
<source src="https://www.w3schools.com/html/horse.ogg" type="audio/ogg">
<source src="https://www.w3schools.com/html/horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
In my case, a click on a button causes a (not wanted) reload of the page.
Here is my fix:
<button class="btn btn-success" onclick="javascript: return false;"
data-target="#modalID" data-toggle="modal">deaktivieren</button>
If you want you can throw a new Exception, with the original one set as an inner exception.
You should be able to use the "client.ResponseHeaders[..]" call, see this link for examples of getting stuff back from the response
Try this
ALTER TABLE table_name ALTER COLUMN col_name data_type NOT NULL;
For those using Jenkins or other CI server: it matters where you define your proxies, especially when they're different in your local development environment and the CI environment. In this case:
403 Forbidden
with little hint to the fact that you're using the wrong proxy. Check your gradle.properties
or such and fix/override as necessary.TLDR: define proxies not in the project but on the machine you're working on.
In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)
You can get the length of any 2nd dimension array as z[n].length
where 0 <= n < z.length
.
If you're treating your 2D array as a matrix, you can simply get z.length
and z[0].length
, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).

If you really want to prune your history of .gitignore
d files, first save .gitignore
outside the repo, e.g. as /tmp/.gitignore
, then run
git filter-branch --force --index-filter \
"git ls-files -i -X /tmp/.gitignore | xargs -r git rm --cached --ignore-unmatch -rf" \
--prune-empty --tag-name-filter cat -- --all
Notes:
git filter-branch --index-filter
runs in the .git
directory I think, i.e. if you want to use a relative path you have to prepend one more ../
first. And apparently you cannot use ../.gitignore
, the actual .gitignore
file, that yields a "fatal: cannot use ../.gitignore as an exclude file" for some reason (maybe during a git filter-branch --index-filter
the working directory is (considered) empty?)git ls-files -iX <(git show $(git hash-object -w .gitignore))
instead to avoid copying .gitignore
somewhere else, but that alone already returns an empty string (whereas cat <(git show $(git hash-object -w .gitignore))
indeed prints .gitignore
's contents as expected), so I cannot use <(git show $GITIGNORE_HASH)
in git filter-branch
....gitignore
-clean a specific branch, replace --all
in the last line with its name. The --tag-name-filter cat
might not work properly then, i.e. you'll probably not be able to directly transfer a single branch's tags properlyHere's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):
var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
{
DefaultExt = "*.xml",
Filter = "BIN Files (*.bin)|*.bin",
InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
};
var result = saveFileDialog.ShowDialog();
if (result != null && result == true)
{
// Save the file here
}
Here the solution for my case ( private repos, free account plan)
The image build name to push has to have the same name of the repos.
Example: repos on docker hub is: accountName/resposName image build name "accountName/resposName" -> docker build -t accountName/resposName
then type docker push accountName/resposName:latest
That's all.
I used the System.Xml.Linq.XElement for the purpose. Just check code below for reading the value of first child node of the xml(not the root node).
string textXml = "<xmlroot><firstchild>value of first child</firstchild>........</xmlroot>";
XElement xmlroot = XElement.Parse(textXml);
string firstNodeContent = ((System.Xml.Linq.XElement)(xmlroot.FirstNode)).Value;
Two possibilities when this can happen -
You have cloned a project and, somehow, the .git directory got deleted or corrupted. This leads Git to be unaware of your local history and will, therefore, cause it to throw this error when you try to push to or pull from the remote repository.
You have created a new repository, added a few commits to it, and now you are trying to pull from a remote repository that already has some commits of its own. Git will also throw the error in this case, since it has no idea how the two projects are related.
SOLUTION
git pull origin master --allow-unrelated-histories

I may consider performance and memory utilization. One big difference is that EAGER fetch strategy allows to use fetched data object without session. Why?
All data is fetched when eager marked data in the object when session is connected. However, in case of lazy loading strategy, lazy loading marked object does not retrieve data if session is disconnected (after session.close()
statement). All that can be made by hibernate proxy. Eager strategy lets data to be still available after closing session.
yearList = arrayListOf()
for (year in 1950 until 2021) {
yearList.add(year)
}
yearList.reverse()
val list: ArrayList<String> = arrayListOf()
for (year in yearList) {
list.add(year.toString())
}
Use array-like fields:
<input name="name_for_the_items[]"/>
You can loop through the fields:
foreach($_POST['name_for_the_items'] as $item)
{
//do something with $item
}
It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

For any one having this issue with Flurry framework. This is what fixed my issue. For me the issue was that i had imported the following files but never used them. "libFlurryTVOS_9.2.3" "libFlurryWatch_9.2.3"
So all I had to do was go to project target settings and remove these 2 files from the "Linked framework and libraries" section and the problem was solved.
You can try converting your image from tiff to PNG, here is how to do it:
import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;
public class ImgConvTiffToPng {
public static byte[] convert(byte[] tiff) throws Exception {
byte[] out = new byte[0];
InputStream inputStream = new ByteArrayInputStream(tiff);
TIFFDecodeParam param = null;
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
RenderedImage op = dec.decodeAsRenderedImage(0);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
PNGEncodeParam jpgparam = null;
ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
en.encode(op);
outputStream = (ByteArrayOutputStream) en.getOutputStream();
out = outputStream.toByteArray();
outputStream.flush();
outputStream.close();
return out;
}
In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode

If you installed pip like this:
- sudo apt install python-pip
- sudo apt install python3-pip
Uninstall them like this:
- sudo apt remove python-pip
- sudo apt remove python3-pip
I think the best way to do that is to first read the file into a byte array, then convert the array to an image with ImageIO.read()
I would vote against display: inline-block
since its not supported across browsers, IE < 8 specifically.
.wrapper {
width:500px; /* Adjust to a total width of both .left and .right */
margin: 0 auto;
}
.left {
float: left;
width: 49%; /* Not 50% because of 1px border. */
border: 1px solid #000;
}
.right {
float: right;
width: 49%; /* Not 50% because of 1px border. */
border: 1px solid #F00;
}
<div class="wrapper">
<div class="left">Div 1</div>
<div class="right">Div 2</div>
</div>
EDIT: If no spacing between the cells is desired just change both .left
and .right
to use float: left;
The difference between undefined
and null
is minimal, but there is a difference. A variable whose value is undefined
has never been initialized. A variable whose value is null
was explicitly given a value of null
, which means that the variable was explicitly set to have no value. If you compare undefined
and null
by using the null==undefined
expression, they will be equal.
I have another even simpler solution, to be used without autolayout and with everything done through the XIB :
1/ Put your header in the tableview by drag and dropping it directly on the tableview.
2/ In the Size Inspector of the newly made header, just change its autosizing : you should only leave the top, left and right anchors, plus the fill horizontally.
That should do the trick !
If you want to remove leading and ending spaces, use str.strip()
:
sentence = ' hello apple'
sentence.strip()
>>> 'hello apple'
If you want to remove all space characters, use str.replace()
:
(NB this only removes the “normal” ASCII space character ' ' U+0020
but not any other whitespace)
sentence = ' hello apple'
sentence.replace(" ", "")
>>> 'helloapple'
If you want to remove duplicated spaces, use str.split()
:
sentence = ' hello apple'
" ".join(sentence.split())
>>> 'hello apple'
Before answering let's add some background, explaining what is this HEAD
. since some of the options below will result in detached head
First of all what is HEAD?
HEAD
is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD
at any given time. (excluding git worktree
)
The content of HEAD
is stored inside .git/HEAD
and it contains the 40 bytes SHA-1 of the current commit.
detached HEAD
If you are not on the latest commit - meaning that HEAD
is pointing to a prior commit in history its called detached HEAD
.
On the command line, it will look like this- SHA-1 instead of the branch name since the HEAD
is not pointing to the tip of the current branch
git checkout
git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back
This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.
# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>
# create a new branch forked to the given commit
git checkout -b <branch name>
git reflog
You can always use the reflog
as well.
git reflog
will display any change which updated the HEAD
and checking out the desired reflog entry will set the HEAD
back to this commit.
Every time the HEAD is modified there will be a new entry in the reflog
git reflog
git checkout HEAD@{...}
This will get you back to your desired commit
git reset --hard <commit_id>
"Move" your HEAD back to the desired commit.
# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32
# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.
git rebase --no-autostash
as well.git revert <sha-1>
"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.
# add new commit with the undo of the original one.
# the <sha-1> can be any commit(s) or commit range
git revert <sha-1>
This schema illustrates which command does what.
As you can see there reset && checkout
modify the HEAD
.
Make sure the build variant is set to debug (and not release) in Android Studio (check the build variants panel).
You can only make DNS name pont to a different IP address, so if You you are using virtual hosts redirecting with DNS won't work.
When you enter subdomain.hostone.com in your browser it will use DNS to get it's IP address (if it's a CNAME it will continue trying until it gets IP from A record) then it will connect to that IP and send a http request with
Host: subdomain.hostone.com
somewhere in the http headers.
From the "View" menu, select "Workspaces". You'll see all of the workspaces you've created. Select the workspaces you want to delete and click "Edit" -> "Delete Workspace", or right-click and select "Delete Workspace". If the workspace is "locked" to prevent changes, you'll get an error message.
To unlock the workspace, click "Edit" (or right-click and click "Edit Workspace") to pull up the workspace editor, uncheck the "locked" checkbox, and save your changes. You can delete the workspace once it's unlocked.
In my experience, the workspace will continue to be shown in the drop-down list until you click on it, at which point p4v will figure out you've deleted it and remove it from the list.
You could implement a JavaScript block which contains a function with your needs.
<div style="position: absolute; left: 10px; top: 40px;">
<img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>
According to your sample,
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script src="abc.js" type="text/javascript">
</script>
<link rel="stylesheets" type="text/css" href="abc.css"></link>
<style>h2{font-wight:bold;}</style>
<script>
$(document).ready(function(){
$("#img").attr("src", "kkk.png");
});
</script>
</head>
<body>
<img id="img" src="abc.jpg" style="width:400px;height:300px;"/>
<script src="kkk.js" type="text/javascript"></script>
</body>
</html>
roughly the execution flow is about as follows:
<script src="jquery.js" ...
jquery.js
is downloaded and parsed<script src="abc.js" ...
abc.js
is downloaded, parsed and run<link href="abc.css" ...
abc.css
is downloaded and parsed<style>...</style>
<script>...</script>
<img src="abc.jpg" ...
abc.jpg
is downloaded and displayed<script src="kkk.js" ...
kkk.js
is downloaded, parsed and runNote that the download may be asynchronous and non-blocking due to behaviours of the browser. For example, in Firefox there is this setting which limits the number of simultaneous requests per domain.
Also depending on whether the component has already been cached or not, the component may not be requested again in a near-future request. If the component has been cached, the component will be loaded from the cache instead of the actual URL.
When the parsing is ended and document is ready and loaded, the events onload
is fired. Thus when onload
is fired, the $("#img").attr("src","kkk.png");
is run. So:
$("#img").attr("src", "kkk.png");
kkk.png
is downloaded and loads into #img
The $(document).ready()
event is actually the event fired when all page components are loaded and ready. Read more about it: http://docs.jquery.com/Tutorials:Introducing_$(document).ready()
By default, and from my current understanding, browser usually runs each page on 3 ways: HTML parser, Javascript/DOM, and CSS.
The HTML parser is responsible for parsing and interpreting the markup language and thus must be able to make calls to the other 2 components.
For example when the parser comes across this line:
<a href="#" onclick="alert('test');return false;" style="font-weight:bold">a hypertext link</a>
The parser will make 3 calls, two to Javascript and one to CSS. Firstly, the parser will create this element and register it in the DOM namespace, together with all the attributes related to this element. Secondly, the parser will call to bind the onclick event to this particular element. Lastly, it will make another call to the CSS thread to apply the CSS style to this particular element.
The execution is top down and single threaded. Javascript may look multi-threaded, but the fact is that Javascript is single threaded. This is why when loading external javascript file, the parsing of the main HTML page is suspended.
However, the CSS files can be download simultaneously because CSS rules are always being applied - meaning to say elements are always repainted with the freshest CSS rules defined - thus making it unblocking.
An element will only be available in the DOM after it has been parsed. Thus when working with a specific element, the script is always placed after, or within the window onload event.
Script like this will cause error (on jQuery):
<script type="text/javascript">/* <![CDATA[ */
alert($("#mydiv").html());
/* ]]> */</script>
<div id="mydiv">Hello World</div>
Because when the script is parsed, #mydiv
element is still not defined. Instead this would work:
<div id="mydiv">Hello World</div>
<script type="text/javascript">/* <![CDATA[ */
alert($("#mydiv").html());
/* ]]> */</script>
OR
<script type="text/javascript">/* <![CDATA[ */
$(window).ready(function(){
alert($("#mydiv").html());
});
/* ]]> */</script>
<div id="mydiv">Hello World</div>

Go to Edit > Replace in Files
From there it is similar to the search funtionality for a single file.
I changed the name of a class I was using across files and this worked perfectly.
Note: If you cannot find the Replace in Files option, first click on the Search icon (magnifying glass) and then it will appear.
The correct way to hide/change the Toolbar Title is this:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(null);
This because when you call setSupportActionBar(toolbar);
, then the getSupportActionBar()
will be responsible of handling everything to the Action Bar, not the toolbar object.

list objects are unhashable. you might want to turn them in to tuples though.
Multiple clients can connect to the same port (say 80) on the server because on the server side, after creating a socket and binding (setting local IP and port) listen is called on the socket which tells the OS to accept incoming connections.
When a client tries to connect to server on port 80, the accept call is invoked on the server socket. This creates a new socket for the client trying to connect and similarly new sockets will be created for subsequent clients using same port 80.
Words in italics are system calls.

I resolved the problem with this code:
HTML Form
<input type="checkbox" id="is-business" name="is-business" value="off" onclick="changeValueCheckbox(this)" >
<label for="is-business">Soy empresa</label>
and the javascript function by change the checkbox value form:
//change value of checkbox element
function changeValueCheckbox(element){
if(element.checked){
element.value='on';
}else{
element.value='off';
}
}
and the server checked if the data post is "on" or "off". I used playframework java
final Map<String, String[]> data = request().body().asFormUrlEncoded();
if (data.get("is-business")[0].equals('on')) {
login.setType(new MasterValue(Login.BUSINESS_TYPE));
} else {
login.setType(new MasterValue(Login.USER_TYPE));
}
Just add ?author=<emailaddress>
or ?author=<githubUserName>
to the url when viewing the "commits" section of a repo.
If you mean the first and last entry of the array when talking about a.first and a.last, it goes like this:
foreach ($arr_nav as $inner_array) {
echo reset($inner_array); //apple, orange, pear
echo end($inner_array); //My Apple, View All Oranges, A Pear
}
arrays in PHP have an internal pointer which you can manipulate with reset, next, end. Retrieving keys/values works with key and current, but using each might be better in many cases..
I think you have downloaded the .NET Reflector & this FileGenerator plugin http://filegenreflector.codeplex.com/ , If you do,
Open up the Reflector.exe,
Go to View and click Add-Ins,
In the Add-Ins window click Add...,
Then find the dll you have downloaded
FileGenerator.dll (witch came wth the FileGenerator plugin),
Then close the Add-Ins window.
Go to File and click Open and choose the dll that you want to decompile,
After you have opend it, it will appear in the tree view,
Go to Tools and click Generate Files(Crtl+Shift+G),
select the output directory and select appropriate settings as your wish, Click generate files.
OR
may be you could add a attribute to your EditText like this:
android:imeOptions="actionSearch"
All previous answers are correct here is a very simple example:
#! /usr/bin/env python
import json
def write_json():
# create a dictionary
student_data = {"students":[]}
#create a list
data_holder = student_data["students"]
# just a counter
counter = 0
#loop through if you have multiple items..
while counter < 3:
data_holder.append({'id':counter})
data_holder.append({'room':counter})
counter += 1
#write the file
file_path='/tmp/student_data.json'
with open(file_path, 'w') as outfile:
print("writing file to: ",file_path)
# HERE IS WHERE THE MAGIC HAPPENS
json.dump(student_data, outfile)
outfile.close()
print("done")
write_json()
With JDBC 4.2 or later and java 8 or later:
myPreparedStatement.setObject( … , myLocalDate )
…and…
myResultSet.getObject( … , LocalDate.class )
The Answer by Vargas is good about mentioning java.time types but refers only to converting to java.sql.Date. No need to convert if your driver is updated.
The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date
, .Calendar
, & java.text.SimpleDateFormat
. The Joda-Time team also advises migration to java.time.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.
Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.
LocalDate
In java.time, the java.time.LocalDate
class represents a date-only value without time-of-day and without time zone.
If using a JDBC driver compliant with JDBC 4.2 or later spec, no need to use the old java.sql.Date
class. You can pass/fetch LocalDate
objects directly to/from your database via PreparedStatement::setObject
and ResultSet::getObject
.
LocalDate localDate = LocalDate.now( ZoneId.of( "America/Montreal" ) );
myPreparedStatement.setObject( 1 , localDate );
…and…
LocalDate localDate = myResultSet.getObject( 1 , LocalDate.class );
If your driver cannot handle the java.time types directly, fall back to converting to java.sql types. But minimize their use, with your business logic using only java.time types.
New methods have been added to the old classes for conversion to/from java.time types. For java.sql.Date
see the valueOf
and toLocalDate
methods.
java.sql.Date sqlDate = java.sql.Date.valueOf( localDate );
…and…
LocalDate localDate = sqlDate.toLocalDate();
Be wary of using 0000-00-00
as a placeholder value as shown in your Question’s code. Not all databases and other software can handle going back that far in time. I suggest using something like the commonly-used Unix/Posix epoch reference date of 1970, 1970-01-01
.
LocalDate EPOCH_DATE = LocalDate.ofEpochDay( 0 ); // 1970-01-01 is day 0 in Epoch counting.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

In Swift 3:
webView.loadHTMLString("<img src=\"myImg.jpg\">", baseURL: Bundle.main.bundleURL)
This worked for me even when the image was inside of a folder without any modifications.
Isn't it Simple as this,
txtbox1.BorderColor = System.Drawing.Color.Red;
select translate(description,'\\t','') from myTable;
Translates the input string by replacing the characters present in the from string with the corresponding characters in the to string. This is similar to the translate function in PostgreSQL. If any of the parameters to this UDF are NULL, the result is NULL as well. (Available as of Hive 0.10.0, for string types)

Depending what size you want your div
to be, you could utilize Bootstrap's built-in component thumbnail
class, along with (or without) the grid system to create borders around each of your div
items.
These examples on Bootstrap's website demonstrates the ease-of-use and lack of need for any special additional CSS
:
<div class="row">
<div class="col-xs-6 col-md-3">
<a href="#" class="thumbnail">
<img src="..." alt="...">
</a>
</div>
...
</div>
which produces the following div
grid items:
or add some additional content:
<div class="row">
<div class="col-sm-6 col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<h3>Thumbnail label</h3>
<p>...</p>
<p>
<a href="#" class="btn btn-primary" role="button">Button</a>
<a href="#" class="btn btn-default" role="button">Button</a>
</p>
</div>
</div>
</div>
</div>
which produces the following div
grid items:
I solved the same problem following this example:
This example uses the jQuery JavaScript library.
First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML :
<img src="/images/loading.gif" id="loading-indicator" style="display:none" />
And the following to your CSS file:
#loading-indicator {
position: absolute;
left: 10px;
top: 10px;
}
Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:
$(document).ajaxSend(function(event, request, settings) {
$('#loading-indicator').show();
});
$(document).ajaxComplete(function(event, request, settings) {
$('#loading-indicator').hide();
});
This solution is from the following link. How to display an animated icon during Ajax request processing
Change in active architecture worked for me, One of my lib was using i386.

Changing your passwords is a good idea, but for the process of removing password's from your repo's history, I recommend the BFG Repo-Cleaner, a faster, simpler alternative to git-filter-branch
explicitly designed for removing private data from Git repos.
Create a private.txt
file listing the passwords, etc, that you want to remove (one entry per line) and then run this command:
$ java -jar bfg.jar --replace-text private.txt my-repo.git
All files under a threshold size (1MB by default) in your repo's history will be scanned, and any matching string (that isn't in your latest commit) will be replaced with the string "***REMOVED***". You can then use git gc
to clean away the dead data:
$ git gc --prune=now --aggressive
The BFG is typically 10-50x faster than running git-filter-branch
and the options are simplified and tailored around these two common use-cases:
Full disclosure: I'm the author of the BFG Repo-Cleaner.
First read your excel spreadsheet into pandas, below code will import your excel spreadsheet into pandas as a OrderedDict type which contain all of your worksheet as dataframes. Then simply use worksheet_name as a key to access specific worksheet as a dataframe and save only required worksheet as csv file by using df.to_csv(). Hope this will workout in your case.
import pandas as pd
df = pd.read_excel('YourExcel.xlsx', sheet_name=None)
df['worksheet_name'].to_csv('YourCsv.csv')
If your Excel file contain only one worksheet then simply use below code:
import pandas as pd
df = pd.read_excel('YourExcel.xlsx')
df.to_csv('YourCsv.csv')
If someone want to convert all the excel worksheets from single excel workbook to the different csv files, try below code:
import pandas as pd
def excelTOcsv(filename):
df = pd.read_excel(filename, sheet_name=None)
for key, value in df.items():
return df[key].to_csv('%s.csv' %key)
This function is working as a multiple Excel sheet of same excel workbook to multiple csv file converter. Where key is the sheet name and value is the content inside sheet.
You need to use method Array.filter
:
this.persons = this.personService.getPersons().filter(x => x.id == this.personId)[0];
or Array.find
this.persons = this.personService.getPersons().find(x => x.id == this.personId);
You can use the DataColumnCollection of Your datatable to check if the column is in the collection.
Something like:
DataColumnCollection Columns = dtItems.Columns;
if (Columns.Contains(ColNameToCheck))
{
row["ColNameToCheck"] = "Checked";
}
Well you can convert one byte (unsigned char) at a time into a array like so
char buffer [17];
buffer[16] = 0;
for(j = 0; j < 8; j++)
sprintf(&buffer[2*j], "%02X", data[j]);
Wouldn't it be easier to negative-match alphanumerics instead?
return string.match(/^[^a-zA-Z0-9]+$/) ? true : false;
I had this on a form where the Recordsource is dynamic.
The Sql was fine, answer is to trap the error!
Private Sub Form_Error(DataErr As Integer, Response As Integer)
' Debug.Print DataErr
If DataErr = 3075 Then
Response = acDataErrContinue
End If
End Sub
if you're looking for a simple column hide you can use the :nth-child selector as well.
#tableid tr td:nth-child(3),
#tableid tr th:nth-child(3) {
display: none;
}
I use this with the @media tag sometimes to condense wider tables when the screen is too narrow.
Suppose you have created a new branch on GitHub with the name feature-branch.
FETCH
git pull --all Pull all remote branches
git branch -a List all branches now
Checkout and switch to the feature-branch directory. You can simply copy the branch name from the output of branch -a command above
git checkout -b feature-branch
VALIDATE
Next use the git branch command to see the current branch. It will show feature-branch with * In front of it
git branch
COMMIT
git add . add all files
git commit -m "Rafactore code or use your message"
Take update and the push changes on the origin server
git pull origin feature-branch
git push origin feature-branch
Your application is not able to connect to activemq. Check that your activemq is running and listening on localhost 61616.
You can try using: netstat -a
to check if the activemq process has started. Or try check if you can access your actvemq using admin page: localhost:8161/admin/queues.jsp
On mac you will start your activemq using:
$ACTMQ_HOME/bin/activemq start
Or if your config file (activemq.xml ) if located in another location you can use:
$ACTMQ_HOME/bin/activemq start xbean:file:${location_of_your_config_file}
In your case the executable is under: bin/macosx/activemq
so you need to use: $ACTMQ_HOME/bin/macosx/activemq start
There is a huge difference in the behaviour of #
vs javascript:void(0);
.
#
scrolls you to the top of the page but javascript:void(0);
does not.
This is very important if you are coding dynamic pages because the user does not want to go back to the top when they click a link on the page.
I did not find a CRTP implementation among the answers, so here it is:
template<typename HeirT>
class Singleton
{
public:
Singleton() = delete;
Singleton(const Singleton &) = delete;
Singleton &operator=(const Singleton &) = delete;
static HeirT &instance()
{
static HeirT instance;
return instance;
}
};
To use just inherit your class from this, like: class Test : public Singleton<Test>
str = str.replaceAll("\\r\\n|\\r|\\n", " ");
Worked perfectly for me after searching a lot, having failed with every other line.

>>> 'damn' in li
False
Don't know why @Janos deleted his answer, but it's correct: your data frame Train
doesn't have a column named pre
. When you pass a formula and a data frame to a model-fitting function, the names in the formula have to refer to columns in the data frame. Your Train
has columns called residual.sugar
, total.sulfur
, alcohol
and quality
. You need to change either your formula or your data frame so they're consistent with each other.
And just to clarify: Pre
is an object containing a formula. That formula contains a reference to the variable pre
. It's the latter that has to be consistent with the data frame.
Somehow, the Build checkbox in the Configuration Manager had been unchecked for my executable, so it was still running with the old Any CPU build. After I fixed that, Visual Studio complained that it couldn't debug the assembly, but that was fixed with a restart.

I was trying to map an IEnumerable to an object. This is way I got this error. Maybe it helps.
You can use the createQuery
method (direct in the controller) :
$query = $em->createQuery("SELECT o FROM AcmeCodeBundle:Orders o WHERE o.OrderMail = :ordermail and o.Product like :searchterm")
->setParameter('searchterm', '%'.$searchterm.'%')
->setParameter('ordermail', '[email protected]');
You need to change AcmeCodeBundle to match your bundle name
Or even better - create a repository class for the entity and create a method in there - this will make it reusable

I used this in a style sheet for three columns separated by vertical borders and it worked fine:
#column-left {
border-left: 1px solid #dddddd;
}
#column-center {
/*no border needed/*
}
#column-right {
border-right: 1px solid #dddddd;
}
The column on the left gets a border on the right, the column on the right gets a border on the left and the the middle column is already taken care of by the left and right.
If your columns are inside a div/wrapper/table/etc... don't forget to add extra space to accomodate the width of the borders.
To add to the valuable content, I would like to create this reminder on why sometimes RegEx within VBA is not ideal. Not all expressions are supported, but instead may throw an Error 5017
and may leave the author guessing (which I am a victim of myself).
Whilst we can find some sources on what is supported, it would be helpfull to know which metacharacters etc. are not supported. A more in-depth explaination can be found here. Mentioned in this source:
"Although "VBScript’s regular expression ... version 5.5 implements quite a few essential regex features that were missing in previous versions of VBScript. ... JavaScript and VBScript implement Perl-style regular expressions. However, they lack quite a number of advanced features available in Perl and other modern regular expression flavors:"
So, not supported are:
\A
, alternatively use the ^
caret to match postion before 1st char in string\Z
, alternatively use the $
dollar sign to match postion after last char in string(?<=a)b
(whilst postive LookAhead is supported)(?<!a)b
(whilst negative LookAhead is supported)\{uFFFF}
/i
(case sensitivity) or /g
(global) etc. Set these through the RegExp
object properties > RegExp.Global = True
and RegExp.IgnoreCase = True
if available.'
comments in script I already hit a wall more than once using regular expressions within VBA. Usually with LookBehind
but sometimes I even forget the modifiers. I have not experienced all these above mentioned backdrops myself but thought I would try to be extensive referring to some more in-depth information. Feel free to comment/correct/add. Big shout out to regular-expressions.info for a wealth of information.
P.S. You have mentioned regular VBA methods and functions, and I can confirm they (at least to myself) have been helpful in their own ways where RegEx would fail.
You can also use the same syntax for an array. For example, searching within a Pandas series:
ser = pd.Series(['some', 'strings', 'to', 'query'])
if item in ser.values:
# do stuff
If you have queries that will be frequently using a relatively static set of columns, creating a single covering index that includes them all will improve performance dramatically.
By putting multiple columns in your index, the optimizer will only have to access the table directly if a column is not in the index. I use these a lot in data warehousing. The downside is that doing this can cost a lot of overhead, especially if the data is very volatile.
Creating indexes on single columns is useful for lookup operations frequently found in OLTP systems.
You should ask yourself why you're indexing the columns and how they'll be used. Run some query plans and see when they are being accessed. Index tuning is as much instinct as science.
Try this (in the psql
command-line tool):

This is blatant rip-off of Christian's excellent answer. I've just made it a bit more readable:
/**
* objectInspector digs through a Javascript object
* to display all its properties
*
* @param object - a Javascript object to inspect
* @param result - a string of properties with datatypes
*
* @return result - the concatenated description of all object properties
*/
function objectInspector(object, result) {
if (typeof object != "object")
return "Invalid object";
if (typeof result == "undefined")
result = '';
if (result.length > 50)
return "[RECURSION TOO DEEP. ABORTING.]";
var rows = [];
for (var property in object) {
var datatype = typeof object[property];
var tempDescription = result+'"'+property+'"';
tempDescription += ' ('+datatype+') => ';
if (datatype == "object")
tempDescription += 'object: '+objectInspector(object[property],result+' ');
else
tempDescription += object[property];
rows.push(tempDescription);
}//Close for
return rows.join(result+"\n");
}//End objectInspector
Just as a normal js object:
let myhash: IHash = {};
myhash["somestring"] = "value"; //set
let value = myhash["somestring"]; //get
There are two things you're doing with [indexer: string] : string
You can make a general dictionary with explicitly typed fields by using [key: string]: any;
e.g. age
must be number
, while name
must be a string - both are required. Any implicit field can be any type of value.
As an alternative, there is a Map
class:
let map = new Map<object, string>();
let key = new Object();
map.set(key, "value");
map.get(key); // return "value"
This allows you have any Object instance (not just number/string) as the key.
Although its relatively new so you may have to polyfill it if you target old systems.

When [dropping] the encoding settings mentioned above all characters [are rendered] correctly but the encoding that is detected shows either windows-1252 or ISO-8859-1 depending on the browser.
Then that's what you're really sending. None of the encoding settings in your bullet list will actually modify your output in any way; all they do is tell the browser what encoding to assume when interpreting what you send. That's why you're getting those ?s - you're telling the browser that what you're sending is UTF-8, but it's really ISO-8859-1.
git branch --contains <ref>
is the most obvious "porcelain" command to do this. If you want to do something similar with only "plumbing" commands:

if $(git rev-list $BRANCH | fgrep -q $COMMIT); then
echo $BRANCH

And to write this block in another line/file, go to the desired position and execute next command (insert file written before):
:r /tmp/yank
(Reminder: don't forget to remove file: /tmp/yank)
I would like to extend nice answer of Jerome Dalbert. I found very easy to write your own annotation validators in JSR-303 way. You are not limited to have "one field" validation. You can create your own annotation on type level and have complex validation (see examples below). I prefer this way because I don't need mix different types of validation (Spring and JSR-303) like Jerome do. Also this validators are "Spring aware" so you can use @Inject/@Autowire out of box.
Example of custom object validation:
@Target({ TYPE, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { YourCustomObjectValidator.class })
public @interface YourCustomObjectValid {
String message() default "{YourCustomObjectValid.message}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
public class YourCustomObjectValidator implements ConstraintValidator<YourCustomObjectValid, YourCustomObject> {
@Override
public void initialize(YourCustomObjectValid constraintAnnotation) { }
@Override
public boolean isValid(YourCustomObject value, ConstraintValidatorContext context) {
// Validate your complex logic
// Mark field with error
ConstraintViolationBuilder cvb = context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate());
cvb.addNode(someField).addConstraintViolation();
return true;
}
}
@YourCustomObjectValid
public YourCustomObject {
}

I'm using Pop OS 20.04 and I have Java versions 8, 11 and 14 installed on my notebook.
This error was happening to me when version 14 was standard.
When I switched to using version 11 as the default, the error no longer occurred.

The hasClass method will accept an array of class names as an argument, you can do something like this:
$(document).ready(function() {
function filterFilesList() {
var rows = $('.file-row');
var checked = $("#filterControls :checkbox:checked");
if (checked.length) {
var criteriaCollection = [];
checked.each(function() {
criteriaCollection.push($(this).val());
});
rows.each(function() {
var row = $(this);
var rowMatch = row.hasClass(criteriaCollection);
if (rowMatch) {
row.show();
} else {
row.hide(200);
}
});
} else {
rows.each(function() {
$(this).show();
});
}
}
$("#filterControls :checkbox").click(filterFilesList);
filterFilesList();
});
You have to update your app.config file manually
// Load the app.config file
XmlDocument xml = new XmlDocument();
xml.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
// Do whatever you need, like modifying the appSettings section
// Save the new setting
xml.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
And then tell your application to reload any section you modified
ConfigurationManager.RefreshSection("appSettings");
I couldn't figure out how to use the API using the first Google results. Fortunately a thread somewhere pointed me to this link: http://access.mvps.org/access/api/api0049.htm
Which works nicely. :)
To expand on Head Geek's answer, there is a faster way to do the addition_is_safe
;
bool addition_is_safe(unsigned int a, unsigned int b)
{
unsigned int L_Mask = std::numeric_limits<unsigned int>::max();
L_Mask >>= 1;
L_Mask = ~L_Mask;
a &= L_Mask;
b &= L_Mask;
return ( a == 0 || b == 0 );
}
This uses machine-architecture safe, in that 64-bit and 32-bit unsigned integers will still work fine. Basically, I create a mask that will mask out all but the most significant bit. Then, I mask both integers, and if either of them do not have that bit set, then addition is safe.
This would be even faster if you pre-initialize the mask in some constructor, since it never changes.
#pragma mark
directives show up in Xcode in the menus for direct access to methods. They have no impact on the program at all.
For example, using it with Xcode 4 will make those items appear directly in the Jump Bar.
There is a special pragma mark -
which creates a line.
They are not the same thing.
x:Name
is a xaml concept, used mainly to reference elements. When you give an element the x:Name xaml attribute, "the specified x:Name
becomes the name of a field that is created in the underlying code when xaml is processed, and that field holds a reference to the object." (MSDN) So, it's a designer-generated field, which has internal access by default.
Name
is the existing string property of a FrameworkElement
, listed as any other wpf element property in the form of a xaml attribute.
As a consequence, this also means x:Name
can be used on a wider range of objects. This is a technique to enable anything in xaml to be referenced by a given name.
The best way I have found is to use jQuery JSON
N.B. - this question and answer relate to the 2000 version of SQL Server. In later versions, the restriction on INSERT INTO @table_variable ... EXEC ...
were lifted and so it doesn't apply for those later versions.
You'll have to switch to a temp table:
CREATE TABLE #tmp (code varchar(50), mount money)
DECLARE @q nvarchar(4000)
SET @q = 'SELECT coa_code, amount FROM T_Ledger_detail'
INSERT INTO #tmp (code, mount)
EXEC sp_executesql (@q)
SELECT * from #tmp
From the documentation:
A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.
Within its scope, a table variable may be used like a regular table. It may be applied anywhere a table or table expression is used in SELECT, INSERT, UPDATE, and DELETE statements. However, table may not be used in the following statements:
INSERT INTO table_variable EXEC stored_procedure
SELECT select_list INTO table_variable statements.
To be able to use std::unordered_map
(or one of the other unordered associative containers) with a user-defined key-type, you need to define two things:
A hash function; this must be a class that overrides operator()
and calculates the hash value given an object of the key-type. One particularly straight-forward way of doing this is to specialize the std::hash
template for your key-type.
A comparison function for equality; this is required because the hash cannot rely on the fact that the hash function will always provide a unique hash value for every distinct key (i.e., it needs to be able to deal with collisions), so it needs a way to compare two given keys for an exact match. You can implement this either as a class that overrides operator()
, or as a specialization of std::equal
, or – easiest of all – by overloading operator==()
for your key type (as you did already).
The difficulty with the hash function is that if your key type consists of several members, you will usually have the hash function calculate hash values for the individual members, and then somehow combine them into one hash value for the entire object. For good performance (i.e., few collisions) you should think carefully about how to combine the individual hash values to ensure you avoid getting the same output for different objects too often.
A fairly good starting point for a hash function is one that uses bit shifting and bitwise XOR to combine the individual hash values. For example, assuming a key-type like this:
struct Key
{
std::string first;
std::string second;
int third;
bool operator==(const Key &other) const
{ return (first == other.first
&& second == other.second
&& third == other.third);
}
};
Here is a simple hash function (adapted from the one used in the cppreference example for user-defined hash functions):
namespace std {
template <>
struct hash<Key>
{
std::size_t operator()(const Key& k) const
{
using std::size_t;
using std::hash;
using std::string;
// Compute individual hash values for first,
// second and third and combine them using XOR
// and bit shifting:
return ((hash<string>()(k.first)
^ (hash<string>()(k.second) << 1)) >> 1)
^ (hash<int>()(k.third) << 1);
}
};
}
With this in place, you can instantiate a std::unordered_map
for the key-type:
int main()
{
std::unordered_map<Key,std::string> m6 = {
{ {"John", "Doe", 12}, "example"},
{ {"Mary", "Sue", 21}, "another"}
};
}
It will automatically use std::hash<Key>
as defined above for the hash value calculations, and the operator==
defined as member function of Key
for equality checks.
If you don't want to specialize template inside the std
namespace (although it's perfectly legal in this case), you can define the hash function as a separate class and add it to the template argument list for the map:
struct KeyHasher
{
std::size_t operator()(const Key& k) const
{
using std::size_t;
using std::hash;
using std::string;
return ((hash<string>()(k.first)
^ (hash<string>()(k.second) << 1)) >> 1)
^ (hash<int>()(k.third) << 1);
}
};
int main()
{
std::unordered_map<Key,std::string,KeyHasher> m6 = {
{ {"John", "Doe", 12}, "example"},
{ {"Mary", "Sue", 21}, "another"}
};
}
How to define a better hash function? As said above, defining a good hash function is important to avoid collisions and get good performance. For a real good one you need to take into account the distribution of possible values of all fields and define a hash function that projects that distribution to a space of possible results as wide and evenly distributed as possible.
This can be difficult; the XOR/bit-shifting method above is probably not a bad start. For a slightly better start, you may use the hash_value
and hash_combine
function template from the Boost library. The former acts in a similar way as std::hash
for standard types (recently also including tuples and other useful standard types); the latter helps you combine individual hash values into one. Here is a rewrite of the hash function that uses the Boost helper functions:
#include <boost/functional/hash.hpp>
struct KeyHasher
{
std::size_t operator()(const Key& k) const
{
using boost::hash_value;
using boost::hash_combine;
// Start with a hash value of 0 .
std::size_t seed = 0;
// Modify 'seed' by XORing and bit-shifting in
// one member of 'Key' after the other:
hash_combine(seed,hash_value(k.first));
hash_combine(seed,hash_value(k.second));
hash_combine(seed,hash_value(k.third));
// Return the result.
return seed;
}
};
And here’s a rewrite that doesn’t use boost, yet uses good method of combining the hashes:
namespace std
{
template <>
struct hash<Key>
{
size_t operator()( const Key& k ) const
{
// Compute individual hash values for first, second and third
// http://stackoverflow.com/a/1646913/126995
size_t res = 17;
res = res * 31 + hash<string>()( k.first );
res = res * 31 + hash<string>()( k.second );
res = res * 31 + hash<int>()( k.third );
return res;
}
};
}
If nearly everything seems right, another thing to look out for is to ensure that the validation summary is not being explicitly hidden via some CSS override like this:
.validation-summary-valid {
display: none;
}
This may also cause the @Html.ValidationSummary
to appear hidden, as the summary is dynamically rendered with the validation-summary-valid
class.
You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.
NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.
Example:
Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.
Returns:
Just be aware that this is not 100%!
Here are a little snippet for you to try out:
import spacy
phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
doc = nlp(phrase)
replaced = ""
for token in doc:
if token in doc.ents:
replaced+="XXXX "
else:
replaced+=token.text+" "
Read more here: https://spacy.io/usage/linguistic-features#named-entities
You could, instead of replacing with XXXX, replace based on the entity type, like:
if ent.label_ == "PERSON":
replaced += "<PERSON> "
Then:
import re, random
personames = ["Jack", "Mike", "Bob", "Dylan"]
phrase = re.replace("<PERSON>", random.choice(personames), phrase)
They have one for free as a sample at http://www.xamltemplates.net/
We can use Angular event bindings to respond to any DOM event. The syntax is simple. We surround the DOM event name in parentheses and assign a quoted template statement to it. -- reference
Since change
is on the list of standard DOM events, we can use it:
(change)="saverange()"
In your particular case, since you're using NgModel, you could break up the two-way binding like this instead:
[ngModel]="range" (ngModelChange)="saverange($event)"
Then
saverange(newValue) {
this.range = newValue;
this.Platform.ready().then(() => {
this.rootRef.child("users").child(this.UserID).child('range').set(this.range)
})
}
However, with this approach saverange()
is called with every keystroke, so you're probably better off using (change)
.
You could simply convert the datetime. Something like:
@Convert.ToString(string.Format("{0:dd/MM/yyyy}", Model.Returndate))
First Build your Project and if it was successful, right click on the "model.tt" file and choose run custom tool. It will fix it.
Again Build your project and point to "model.context.tt" run custom tool. it will update DbSet lists.
My approach:
define a default constraint on the ModDate
column with a value of GETDATE()
- this handles the INSERT
case
have a AFTER UPDATE
trigger to update the ModDate
column
Something like:
CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
UPDATE dbo.TimeEntry
SET ModDate = GETDATE()
WHERE ID IN (SELECT DISTINCT ID FROM Inserted)
Because of double print function. I suggest you to use return
instead of print
inside the function definition.
def lyrics():
return "The very first line"
print(lyrics())
OR
def lyrics():
print("The very first line")
lyrics()
Update: Jenkins 2.x solution:
With Jenkins 2 pipeline dsl, you can directly access any parameter with the trivial syntax based on the params
(Map) built-in:
echo " FOOBAR value: ${params.'FOOBAR'}"
The returned value will be a String or a boolean depending on the Parameter type itself. The syntax is the same for scripted or declarative syntax. More info at: https://jenkins.io/doc/book/pipeline/jenkinsfile/#handling-parameters
Original Answer for Jenkins 1.x:
For Jenkins 1.x, the syntax is based on the build.buildVariableResolver
built-ins:
// ... or if you want the parameter by name ...
def hardcoded_param = "FOOBAR"
def resolver = build.buildVariableResolver
def hardcoded_param_value = resolver.resolve(hardcoded_param)
Please note the official Jenkins Wiki page covers this in more details as well, especially how to iterate upon the build parameters: https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+System+Groovy+script
The salient part is reproduced below:
// get parameters
def parameters = build?.actions.find{ it instanceof ParametersAction }?.parameters
parameters.each {
println "parameter ${it.name}:"
println it.dump()
}
Simple steps: 1.Go to Android Studio. 2.Close all open projects if any. 3.There will be an option which says import non Android Studio Projects(Eclipse ect). 4.Click on it and choose ur project Thats't it enjoy!!!
As said you have to use SVN Check for modification
in GUI and tortoiseproc.exe /command:repostatus /path:"<path-to-version-control-file-or-directory>"
in CLI to see changes related to the root of the <path-to-version-control-file-or-directory>
.
Sadly, but this command won't show ALL local changes, it does show only those changes which are related to the requested directory root. The changes taken separately, like standalone checkouts or orphan external directories in the root subdirectory will be shown as Unversioned or Nested and you might miss to commit/lookup them.
To avoid such condition you have to either call to tortoiseproc.exe /command:repostatus /pathfile:"<path-to-file-with-list-of-items-to-lookup-from>"
(see detailed documentation on the command line: https://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-automation.html), or use some 3dparty applications/utilities/scripts to wrap the call.
I has been wrote my own set of scripts for Windows to automate the call from the Total Commander
: https://sf.net/p/contools/contools/HEAD/tree/trunk/Scripts/Tools/ToolAdaptors/totalcmd/README_EN.txt (search for TortoiseSVN
)
- Opens TortoiseSVN status dialog for a set of WC directories (always opens to show unversioned changes).
Command: call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:repostatus "%P" %S
- Opens TortoiseSVN commit dialogs for a set of WC directories (opens only if has not empty versioned changes).
Command: call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:commit "%P" %S
See the README_EN.txt
for the latest details (you have to execute the configure.bat
before the usage and copy rest of scripts on yourself like call_nowindow.vbs
).
How about:
df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x
To do all these operations in one-liner:
setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))
#[1] name age gender
#<0 rows> (or 0-length row.names)
Or
data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))
I was searching how to do something similar in WPF and I got this solution:
<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<RadioButton
Content="{Binding}"
Command="{Binding Path=DataContext.CustomCommand,
RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType={x:Type ItemsControl}} }"
CommandParameter="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems
-which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate
is using a DataTemplate
, the DataContext
of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl
type.
I was actually running into some strange errors with mp4's a while ago. What fixed it for me was re-encoding the video using known supported codecs (H.264 & MP3).
I actually used the VLC player to do so and it worked fine afterward. I converted using the mentioned codecs H.264/MP3. That solved it for me.
Maybe the problem is not in the format
but in the JavaScript
implementation of the play/ pause
methods. May I suggest visiting the following link where Google developer explains it in a good way?
Additionally, you could choose to use the newer webp
format, which Chrome supports out of the box, but be careful with other browsers. Check the support for it before implementation. Here's a link that describes the mentioned format.
On that note: I've created a small script
that easily converts all standard formats to webp
. You can easily configure it to fit your needs. Here's the Github repo of the same projects.
Normally, the exe can be found in the debug folder, as suggested previously, but not in the release folder, that is disabled by default in my configuration. If you want to activate the release folder, you can do this: BUILD->Batch Build And activate the "build" checkbox in the release configuration. When you click the build button, the exe with some dependencies will be generated. Now you can copy and use it.
You have a few options here. The simplest is to chain your collectors:
Map<String, Map<Integer, List<Person>>> map = people
.collect(Collectors.groupingBy(Person::getName,
Collectors.groupingBy(Person::getAge));
Then to get a list of 18 year old people called Fred you would use:
map.get("Fred").get(18);
A second option is to define a class that represents the grouping. This can be inside Person. This code uses a record
but it could just as easily be a class (with equals
and hashCode
defined) in versions of Java before JEP 359 was added:
class Person {
record NameAge(String name, int age) { }
public NameAge getNameAge() {
return new NameAge(name, age);
}
}
Then you can use:
Map<NameAge, List<Person>> map = people.collect(Collectors.groupingBy(Person::getNameAge));
and search with
map.get(new NameAge("Fred", 18));
Finally if you don't want to implement your own group record then many of the Java frameworks around have a pair
class designed for this type of thing. For example: apache commons pair If you use one of these libraries then you can make the key to the map a pair of the name and age:
Map<Pair<String, Integer>, List<Person>> map =
people.collect(Collectors.groupingBy(p -> Pair.of(p.getName(), p.getAge())));
and retrieve with:
map.get(Pair.of("Fred", 18));
Personally I don't really see much value in generic tuples now that records are available in the language as records display intent better and require very little code.
You can use string.match() and a regular expression for this too:
if(pathname.match(/^\/sub\/1/)) { // you need to escape the slashes
string.match()
will return an array of matching substrings if found, otherwise null.
I know this has already been answered a long time ago, but I made an extension method to hopefully help other people that come to this question.
Code:
public static class WebRequestExtensions
{
public static WebResponse GetResponseWithoutException(this WebRequest request)
{
if (request == null)
{
throw new ArgumentNullException("request");
}
try
{
return request.GetResponse();
}
catch (WebException e)
{
if (e.Response == null)
{
throw;
}
return e.Response;
}
}
}
Usage:
var request = (HttpWebRequest)WebRequest.CreateHttp("http://invalidurl.com");
//... (initialize more fields)
using (var response = (HttpWebResponse)request.GetResponseWithoutException())
{
Console.WriteLine("I got Http Status Code: {0}", response.StatusCode);
}
select 'test', (select name from employee where id=1) as name, (select name from address where id=2) as address ;
To get the percentage of a number, we need to multiply the desired percentage percent by that number. In practice we will have:
function percentage(percent, total) {
return ((percent/ 100) * total).toFixed(2)
}
Example of usage:
const percentResult = percentage(10, 100);
// print 10.00
.toFixed()
is optional for monetary formats.
Modify your Jquery in following way:
$.ajax({
url: someurl,
contentType: 'application/json',
data: JSONObject,
headers: { 'Access-Control-Allow-Origin': '*' }, //add this line
dataType: 'json',
type: 'POST',
success: function (Data) {....}
});
db.users.count()
db.users.remove({})
db.users.count()
Above answers were helpful, but for unknown reasons they did not seem to work. So if you have already installed MySql workbench on your system, instead of downloading the jar files and struggling with the correct version just go to
C:\Program Files (x86)\MySQL\Connector J 8.0
and copy mysql-connector-java-8.0.12
(does not matter what version it is) the jar file in that location and paste it to C:\Program Files\pentaho\design-tools\data-integration\lib
You can use combination of baseUrl
and paths
docs.
Assuming root is on the topmost src
dir(and I read your image properly) use
// tsconfig.json
{
"compilerOptions": {
...
"baseUrl": ".",
"paths": {
"lib/*": [
"src/org/global/lib/*"
]
}
}
}
For webpack
you might also need to add module resolution. For webpack2
this could look like
// webpack.config.js
module.exports = {
resolve: {
...
modules: [
...
'./src/org/global'
]
}
}
try some thing like blow:
SString otherParametersUrServiceNeed = "Company=acompany&Lng=test&MainPeriod=test&UserID=123&CourseDate=8:10:10";
String request = "http://android.schoolportal.gr/Service.svc/SaveValues";
URL url = new URL(request);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(otherParametersUrServiceNeed.getBytes().length));
connection.setUseCaches (false);
DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(otherParametersUrServiceNeed);
JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");
wr.writeBytes(jsonParam.toString());
wr.flush();
wr.close();

To fix your specific error you need to run that command as sudo, ie:
sudo gem install rails --pre
Take the following folder structure
notice:
Now in the index.html.en
file you'll want to put the following markup
<p>
<span>src="check_mark.png"</span>
<img src="check_mark.png" />
<span>I'm purple because I'm referenced from this current directory</span>
</p>
<p>
<span>src="/check_mark.png"</span>
<img src="/check_mark.png" />
<span>I'm green because I'm referenced from the ROOT directory</span>
</p>
<p>
<span>src="subfolder/check_mark.png"</span>
<img src="subfolder/check_mark.png" />
<span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>
<p>
<span>src="/subfolder/check_mark.png"</span>
<img src="/subfolder/check_mark.png" />
<span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>
<p>
<span>src="../subfolder/check_mark.png"</span>
<img src="../subfolder/check_mark.png" />
<span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>
<p>
<span>src="subfolder/subfolder/check_mark.png"</span>
<img src="subfolder/subfolder/check_mark.png" />
<span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>
<p>
<span>src="/subfolder/subfolder/check_mark.png"</span>
<img src="/subfolder/subfolder/check_mark.png" />
<span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>
Now if you load up the index.html.en
file located in the second subfolder
http://example.com/subfolder/subfolder/
This will be your output

I am using microsoft's Android emulator with Android Studio. I have an AMD FX8350. The ARM one in android studio is terribly slow.
The only issue is that it requires Hyper-V which is not available on windows 10 Home.
Its a really quick emulator and it is free. The best emulator I have used.
Because the TOP 1
from the ordered sub-query does not have profile_id = 'u162231993'
Remove where u.id = 'u162231993'
and see results then.
Run the sub-query separately to understand what's going on.
You can try this:
Select To_date ('15/2/2007 00:00:00', 'DD/MM/YYYY HH24:MI:SS'),
To_date ('28/2/2007 10:12', 'DD/MM/YYYY HH24:MI:SS')

To access a variable in a class, you must use $this->myVar
instead of $this->$myvar
.
And, you should use access identifier to declare a variable instead of var
.
Please read the doc here.
I finally got this working.
I think the fact that our project had two different versions of the commons-httpclient jar wasn't helping. Once I sorted that out I found you can do two things...
In code you can put the following:
HttpComponentsClientHttpRequestFactory rf =
(HttpComponentsClientHttpRequestFactory) restTemplate.getRequestFactory();
rf.setReadTimeout(1 * 1000);
rf.setConnectTimeout(1 * 1000);
The first time this code is called it will set the timeout for the HttpComponentsClientHttpRequestFactory
class used by the RestTemplate
. Therefore, all subsequent calls made by RestTemplate
will use the timeout settings defined above.
Or the better option is to do this:
<bean id="RestOperations" class="org.springframework.web.client.RestTemplate">
<constructor-arg>
<bean class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="readTimeout" value="${application.urlReadTimeout}" />
<property name="connectTimeout" value="${application.urlConnectionTimeout}" />
</bean>
</constructor-arg>
</bean>
Where I use the RestOperations
interface in my code and get the timeout values from a properties file.
I had the same issue. It was caused by having the same flag twice, for example:
if $(ConfigurationName) == Release (xcopy "$(TargetDir)." "$(SolutionDir)Deployment\$(ProjectName)\" /e /d /i /y /e)
Observe that the "/e" flag appears twice. Removing the duplicate solved the issue.
Try this:
retVal = Shell("python.exe <full path to your python script>", vbNormalFocus)
replace <full path to your python script>
with the full path
I use icons next to text 99% of the time so I made the change globally:
.fa-2x {
vertical-align: middle;
}
Add 3x, 4x, etc to the same definition as needed.
This work on my side.
ResourceBean resourceBean = initResourceBean();
ResponseEntity<ResourceBean> responseEntity
= new ResponseEntity<ResourceBean>(resourceBean, HttpStatus.ACCEPTED);
when(restTemplate.exchange(
Matchers.anyObject(),
Matchers.any(HttpMethod.class),
Matchers.<HttpEntity> any(),
Matchers.<Class<ResourceBean>> any())
).thenReturn(responseEntity);
Searched everywhere for this and finally found a solution that works for us. Enabling parallel builds (On OSX: preferences -> compiler -> gradle -> "Compile independent modules in parallel"
) and enabling 'make project automatically' brought it down from ~1 min to ~20 sec. Thanks to /u/Covalence.

XPath 2 has a lower-case (and upper-case) string function. That's not quite the same as case-insensitive, but hopefully it will be close enough:
//CD[lower-case(@title)='empire burlesque']
If you are using XPath 1, there is a hack using translate.
Here's a funny answer.
You can declare a final one-element array and change the elements of the array all you want apparently. I'm sure it breaks the very reason why this compiler rule was implemented in the first place but it's handy when you're in a time-bind as I was today.
I actually can't claim credit for this one. It was IntelliJ's recommendation! Feels a bit hacky. But doesn't seem as bad as a global variable so I thought it worth mentioning here. It's just one solution to the problem. Not necessarily the best one.
final int[] tapCount = {0};
addSiteButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
tapCount[0]++;
}
});
Similar to yebmouxing I could not the
xhr.getResponseHeader('Set-Cookie');
method to work. It would only return null even if I had set HTTPOnly to false on my server.
I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:
function getCookie(cookieName){
var cookieArray = document.cookie.split(';');
for(var i=0; i<cookieArray.length; i++){
var cookie = cookieArray[i];
while (cookie.charAt(0)==' '){
cookie = cookie.substring(1);
}
cookieHalves = cookie.split('=');
if(cookieHalves[0]== cookieName){
return cookieHalves[1];
}
}
return "";
}
You could use the RedirectMatch directive in Apache to do something similar you want.
It's pretty simple.
RedirectMatch / http://222.222.222.222/
Anyway, I can't see any reason to do that thing. Aren't you trying to intercept traffic? There are better ways. For Linux boxes as a router: iptables -j REDIRECT + Squid or Apache. For Cisco routers, you can use WCCP to a Cache or Web Server...
My problem was that Notepad++ was crashing on a file I had previously opened; I was unable to open the application at all. This blog post discusses how to delete the data from the "Sessions" file so that Notepad++ will open without having any prior files open:
From the blog post:
Method 1 - edit session.xml
- Open file session.xml in C:\Users\Username\AppData\Roaming\Notepad++ or %APPDATA%\Notepad++
- Delete its contents and save it
- Run Notepad++ , session.xml will get new content automatically
Method 2 - add the -nosession parameter to Notepad++ shortcut
- Create a desktop shortcut referring to your Notepad++ program, e.g. C:\Program Files\Notepad++\notepad++.exe
- Right click on this shortcut
- In the "Target" field add the -nosession parameter so the target field looks exaxtly like (apostrophes included too): "C:\Program Files\Notepad++\notepad++.exe" -nosession
- Save and run Notepad++ from this shortcut icon with no recent files
Note: This is not a permanent setting, this simply deletes the prior session's information / opened files and starts over.
Alternatively, if you know the file which is causing notepad++ to hang, you can simply rename the file and open notepad++. This will solve the problem.
I hadn't seen this solution listed when I was googling my problem so I wanted to add it here!
None of this worked, what worked for me is scaling image down.
So depending on what size you want the image or what resoultion your image is, you can do something like this:
.ok {
transform: perspective(100px) rotateY(0deg) scale(0.5);
transition: transform 1s;
object-fit:contain;
}
.ok:hover{
transform: perspective(100px) rotateY(-10deg) scale(0.5);
}
/* Demo Preview Stuff */
.bad {
max-width: 320px;
object-fit:contain;
transform: perspective(100px) rotateY(0deg);
transition: transform 1s;
}
.bad:hover{
transform: perspective(100px) rotateY(-10deg);
}
div {
text-align: center;
position: relative;
display: flex;
}
h3{
position: absolute;
bottom: 30px;
left: 0;
right: 0;
}
.b {
display: flex;
}
_x000D_
<center>
<h2>Hover on images</h2>
<div class="b">
<div>
<img class="ok" src='https://www.howtogeek.com/wp-content/uploads/2018/10/preview-11.png'>
<h3>Sharp</h3>

<h3>Blurry</h3>

The image should be scaled down, make sure you have a big image resoultion
This way sets the focus and cursor to the end of your input:
div.getElementsByTagName("input")[0].focus();
div.getElementsByTagName("input")[0].setSelectionRange(div.getElementsByTagName("input")[0].value.length,div.getElementsByTagName("input")[0].value.length,"forward");

Assuming userInfoList
is a List<UserInfo>
:
var groups = userInfoList
.GroupBy(n => n.metric)
.Select(n => new
{
MetricName = n.Key,
MetricCount = n.Count()
}
)
.OrderBy(n => n.MetricName);
The lambda function for GroupBy()
, n => n.metric
means that it will get field metric
from every UserInfo
object encountered. The type of n
is depending on the context, in the first occurrence it's of type UserInfo
, because the list contains UserInfo
objects. In the second occurrence n
is of type Grouping
, because now it's a list of Grouping
objects.
Grouping
s have extension methods like .Count()
, .Key()
and pretty much anything else you would expect. Just as you would check .Lenght
on a string
, you can check .Count()
on a group.
//Here is my code to it... work like ninj

if (!contractor) { return next(new Error("can't find contractor")); }
req.contractor = contractor;
return next();
});
});
router.get('/contractors/:contractor/save', function(req, res, next) {
contractor = req.contractor ;
contractor.update({'_id':contractor._id},{upsert: true},function(err,contractor){
if(err){
res.json(err);

Use the Git History Diff plugin for easy side-by-side branch diffing:
https://marketplace.visualstudio.com/items?itemName=huizhou.githd
Visit the link above and scroll down to the animated GIF image titled Diff Branch. You'll see you can easily pick any branch and do side-by-side comparison with the branch you are on! It is like getting a preview of what you will see in the GitHub Pull Request. For other Git stuff I prefer Visual Studio Code's built-in functionality or Git Lens as others have mentioned.
However, the above plugin is outstanding for doing branch diffing (i.e., for those doing a rebase Git flow and need to preview before a force push up to a GitHub PR).
I realize this question is fairly old, but wanted to share a quick demo of group transforms, paths/shapes, and relative positioning, for anyone else who found their way here looking for more info:
Something like this:
$.getJSON("http://mywebsite.com/json/get.php?cid=15",
function(data){
$.each(data.products, function(i,product){
content = '<p>' + product.product_title + '</p>';
content += '<p>' + product.product_short_description + '</p>';
content += '<img src="' + product.product_thumbnail_src + '"/>';
content += '<br/>';
$(content).appendTo("#product_list");
});
});
Would take a json object made from a PHP array returned with the key of products. e.g:
Array('products' => Array(0 => Array('product_title' => 'Product 1',
'product_short_description' => 'Product 1 is a useful product',
'product_thumbnail_src' => '/images/15/1.jpg'
)
1 => Array('product_title' => 'Product 2',
'product_short_description' => 'Product 2 is a not so useful product',
'product_thumbnail_src' => '/images/15/2.jpg'
)
)
)
To reload the list you would simply do:
$("#product_list").empty();
And then call getJSON again with new parameters.
seems if %%
followed with a %@
, the NSString
will go to some strange codes
try this and this worked for me
NSString *str = [NSString stringWithFormat:@"%@%@%@", @"%%",
[textfield text], @"%%"];
Most likely you're looking for something like
var targetElement = document.getElementById('idOfTargetElement');
targetElement.innerHTML = produceMessage();
provided that this is not something which happens on page load, in which case it should already be there from the start.

I think the selected answer is not correct, as the original question is "how to add a new validator after create the formControl".
As far as I know, that's not possible. The only thing you can do, is create the array of validators dynamicaly.
But what we miss is to have a function addValidator() to not override the validators already added to the formControl. If anybody has an answer for that requirement, would be nice to be posted here.
We follow a.b.c approach like:
increament 'a' if there is some major changes happened in application. Like we upgrade .NET 1.1 application to .NET 3.5
increament 'b' if there is some minor changes like any new CR or Enhancement is implemented.
increament 'c' if there is some defects fixes in the code.
I edited you fiddle
you just need to add z-index
to the front element and position it accordingly.
The good, clean, fast, easy and readable ways is:
add something similar like this:
public sealed class myKey : Tuple<TypeA, TypeB, TypeC>
{
public myKey(TypeA dataA, TypeB dataB, TypeC dataC) : base (dataA, dataB, dataC) { }
public TypeA DataA => Item1;
public TypeB DataB => Item2;
public TypeC DataC => Item3;
}
So you can use it with dictionary:
var myDictinaryData = new Dictionary<myKey, string>()
{
{new myKey(1, 2, 3), "data123"},
{new myKey(4, 5, 6), "data456"},
{new myKey(7, 8, 9), "data789"}
};
This is quite simple:
my_data
is a before defined structure type.
So you want to declare an my_data
-array of some elements, as you would do with
char a[] = { 'a', 'b', 'c', 'd' };
So the array would have 4 elements and you initialise them as
a[0] = 'a', a[1] = 'b', a[1] = 'c', a[1] ='d';
This is called a designated initializer (as i remember right).
and it just indicates that data has to be of type my_dat
and has to be an array that needs to store so many my_data structures that there is a structure with each type member name Peter, James, John and Mike.
$('[name="ElementNameHere"]').doStuff();
jQuery supports CSS3 style selectors, plus some more.
Can be done using __reverse__
, which returns a generator.

>>> for i in l.__reversed__():
... print i
...

Store their UserId and a RememberMeToken. When they login with remember me checked generate a new RememberMeToken (which invalidate any other machines which are marked are remember me).
When they return look them up by the remember me token and make sure the UserId matches.
When your class implements Comparable, the compareTo
method of the class is defining the "natural" ordering of that object. That method is contractually obligated (though not demanded) to be in line with other methods on that object, such as a 0 should always be returned for objects when the .equals()
comparisons return true.
A Comparator is its own definition of how to compare two objects, and can be used to compare objects in a way that might not align with the natural ordering.
For example, Strings are generally compared alphabetically. Thus the "a".compareTo("b")
would use alphabetical comparisons. If you wanted to compare Strings on length, you would need to write a custom comparator.
In short, there isn't much difference. They are both ends to similar means. In general implement comparable for natural order, (natural order definition is obviously open to interpretation), and write a comparator for other sorting or comparison needs.
You can always add the @Produces("application/json")
above your web method or specify produces="application/json"
to return json. Then on top of the Student
class you can add @XmlRootElement
from javax.xml.bind.annotation
package.
Please note, it might not be a good idea to directly return model classes. Just a suggestion.
HTH.
Had the same problem. I apparently wrote the Main wrong:
public static void main(String[] args){
I missed the []
and that was the whole problem.
Check and recheck the Main function!

Just wanted to add an important piece of information that I believe was left out perhaps with the assumption that the ones seeking answers might already know. This problem happens a lot and I too found myself stuck when I tried to implement the viewAlert
method for the buttons of the UIAlertView
message. To do this you need to 1st add the delegate class which may look something like this:
@interface YourViewController : UIViewController <UIAlertViewDelegate>
Also you can find a very helpful tutorial here!
Hope this helps.

If you want to delete items after some time, e.g. after a month, just use Time To Live option. It will not count write units.
In your case, I would add ttl when logs expire and leave those after a user is deleted. TTL would make sure logs are removed eventually.
When Time To Live is enabled on a table, a background job checks the TTL attribute of items to see if they are expired.
DynamoDB typically deletes expired items within 48 hours of expiration. The exact duration within which an item truly gets deleted after expiration is specific to the nature of the workload and the size of the table. Items that have expired and not been deleted will still show up in reads, queries, and scans. These items can still be updated and successful updates to change or remove the expiration attribute will be honored.

What you need is properly a service:
.factory('DataLayer', ['$http',
function($http) {
var factory = {};
var locations;
factory.getLocations = function(success) {
if(locations){
success(locations);
return;
}
$http.get('locations/locations.json').success(function(data) {
locations = data;
success(locations);
});
};
return factory;
}
]);
The locations
would be cached in the service which worked as singleton model. This is the right way to fetch data.
Use this service DataLayer
in your controller and directive is ok as following:
appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
DataLayer.getLocations(function(data){
$scope.locations = data;
});
});
.directive('map', function(DataLayer) {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function(scope, element, attrs) {
DataLayer.getLocations(function(data) {
angular.forEach(data, function(location, key){
//do something
});
});
}
};
});
I was getting the same error when I used this code to update the record:
@mysqli_query($dbc,$query or die()))
After removing or die
, it started working properly.
if you have remote server installed on you machine. give server.py host as "localhost" and the port number. then client side , you have to give local ip- 127.0.0.1 and port number. then its works
You need to create own PCH file
Add New file -> Other-> PCH file
Then add the path of this PCH file to your build setting->prefix header->path
($(SRCROOT)/filename.pch)
