You could use PHP's dirname function.
<?php echo dirname(__DIR__); ?>
.
That will give you the name of the parent directory of __DIR__
, which stores the current directory.
I had the same problem. (My problem is with gradle 4.4 files)
Actually the problem is incorrect downloading of 4.4 gradle which already I had.
When I delete gradle 4.4 version
C:\Users\$Your_User\.gradle\wrapper\dists\gradle-4.4-all
Android studio again downloads gradle-4.4 and syncs with my project.
Now it had rectified with the help of Michelin Man
Thanks for your answer Michelin
For quick reference along with clear concise examples, Allen Holub's UML Quick Reference is excellent:
http://www.holub.com/goodies/uml/
(There are quite a few specific examples of arrows and pointers in the first column of a table, with descriptions in the second column.)
$('.parent-div').children(':first').before("<div class='child-div'>some text</div>");
psql -U postgres
Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.
And in the case other db, you may try
psql -U yourdb postgres
As it is given in Postgres help:
psql [OPTION]... [DBNAME [USERNAME]]
url-pattern
is used in web.xml
to map your servlet
to specific URL. Please see below xml code, similar code you may find in your web.xml
configuration file.
<servlet>
<servlet-name>AddPhotoServlet</servlet-name> //servlet name
<servlet-class>upload.AddPhotoServlet</servlet-class> //servlet class
</servlet>
<servlet-mapping>
<servlet-name>AddPhotoServlet</servlet-name> //servlet name
<url-pattern>/AddPhotoServlet</url-pattern> //how it should appear
</servlet-mapping>
If you change url-pattern
of AddPhotoServlet
from /AddPhotoServlet
to /MyUrl
. Then, AddPhotoServlet
servlet can be accessible by using /MyUrl
. Good for the security reason, where you want to hide your actual page URL.
Java Servlet url-pattern
Specification:
- A string beginning with a '/' character and ending with a '/*' suffix is used for path mapping.
- A string beginning with a '*.' prefix is used as an extension mapping.
- A string containing only the '/' character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
- All other strings are used for exact matches only.
Reference : Java Servlet Specification

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
I've implemented what I could gather from a few of these. This works in Windows, and since this is a community wiki, I figure I would share my code as well:
class Command(threading.Thread):
def __init__(self, cmd, outFile, errFile, timeout):
threading.Thread.__init__(self)
self.cmd = cmd
self.process = None
self.outFile = outFile
self.errFile = errFile
self.timed_out = False
self.timeout = timeout
def run(self):
self.process = subprocess.Popen(self.cmd, stdout = self.outFile, \
stderr = self.errFile)
while (self.process.poll() is None and self.timeout > 0):
time.sleep(1)
self.timeout -= 1
if not self.timeout > 0:
self.process.terminate()
self.timed_out = True
else:
self.timed_out = False
Then from another class or file:
outFile = tempfile.SpooledTemporaryFile()
errFile = tempfile.SpooledTemporaryFile()
executor = command.Command(c, outFile, errFile, timeout)
executor.daemon = True
executor.start()
executor.join()
if executor.timed_out:
out = 'timed out'
else:
outFile.seek(0)
errFile.seek(0)
out = outFile.read()
err = errFile.read()
outFile.close()
errFile.close()
Here are the ways to assign parent object in child object of Bi-directional relations ?
Suppose you have a relation say One-To-Many,then for each parent object,a set of child object exists. In bi-directional relations,each child object will have reference to its parent.
eg : Each Department will have list of Employees and each Employee is part of some department.This is called Bi directional relations.
To achieve this, one way is to assign parent in child object while persisting parent object
Parent parent = new Parent();
...
Child c1 = new Child();
...
c1.setParent(parent);
List<Child> children = new ArrayList<Child>();
children.add(c1);
parent.setChilds(children);
session.save(parent);
Other way is, you can do using hibernate Intercepter,this way helps you not to write above code for all models.
Hibernate interceptor provide apis to do your own work before perform any DB operation.Likewise onSave of object, we can assign parent object in child objects using reflection.
public class CustomEntityInterceptor extends EmptyInterceptor {
@Override
public boolean onSave(
final Object entity, final Serializable id, final Object[] state, final String[] propertyNames,
final Type[] types) {
if (types != null) {
for (int i = 0; i < types.length; i++) {
if (types[i].isCollectionType()) {
String propertyName = propertyNames[i];
propertyName = propertyName.substring(0, 1).toUpperCase() + propertyName.substring(1);
try {
Method method = entity.getClass().getMethod("get" + propertyName);
List<Object> objectList = (List<Object>) method.invoke(entity);
if (objectList != null) {
for (Object object : objectList) {
String entityName = entity.getClass().getSimpleName();
Method eachMethod = object.getClass().getMethod("set" + entityName, entity.getClass());
eachMethod.invoke(object, entity);
}
}
} catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) {
throw new RuntimeException(e);
}
}
}
}
return true;
}
}
And you can register Intercepter to configuration as
new Configuration().setInterceptor( new CustomEntityInterceptor() );
You can also do the following
string filename = Path.ChangeExtension(Path.GetTempFileName(), ".csv");
and this also works as expected
string filename = Path.ChangeExtension(Path.GetTempPath() + Guid.NewGuid().ToString(), ".csv");
The w3 org said:
By default, SGML requires that all attribute values be delimited using either double quotation marks (ASCII decimal 34) or single quotation marks (ASCII decimal 39). Single quote marks can be included within the attribute value when the value is delimited by double quote marks, and vice versa. Authors may also use numeric character references to represent double quotes (
"
) and single quotes ('
). For double quotes authors can also use the character entity reference"
.
So... seems to be no difference. Only depends on your style.

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.
However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.
Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:
[client]
user = <username>
password = <password>
Make sure to change the file permissions so that only you can read the file.
Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.
You might find this command helpful to throw away local changes:
git checkout <your-branch> -f
And then do a cleanup (removes untracked files from the working tree):
git clean -f
If you want to remove untracked directories in addition to untracked files:
git clean -fd
To make things even more clearer,
The password + salt is encrypted with a key generated from the: cost, salt and the password. we call that encrypted value the cipher text
. then we attach the salt to this value and encoding it using base64. attaching the cost to it and this is the produced string from bcrypt
:
$2a$COST$BASE64
This value is stored eventually.
In case the attacker got control over the DB, the attacker will decode easily the base64 value, and then he will be able to see the salt. the salt is not secret. though it is random.
Then he will need to decrypt the cipher text
.
What is more important : There is no hashing in this process, rather CPU expensive encryption - decryption. thus rainbow tables are less relevant here.

You must download Android SDK from this link.
You can really put it anywhere, but the best place at least for me was right in the YOUR USERNAME folder root.
Then you need to set the path by copying the below text, but edit your username into the path, copy the text into Terminal by hitting command+spacebar type terminal.
export PATH = ${PATH}:/Users/**YOURUSERNAME**/android-sdk/platform-tools/
Verify ADB works by hitting command+spacebar and type terminal, and type ADB.
There you go. You have ADB setup on MAC OS X. It works on latest MAC OS X 10.10.3.
The ScriptIgnoreAttribute
class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.
You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.
Check this code :
Set objFSO = CreateObject("Scripting.FileSystemObject")
objStartFolder = "C:\Folder1\"
Set objFolder = objFSO.GetFolder(objStartFolder)
Set colFiles = objFolder.Files
For Each objFile in colFiles
strFileName = objFile.Name
If objFSO.GetExtensionName(strFileName) = "pdf" Then
Wscript.Echo objFile.Name
End If
Next
ShowSubfolders objFSO.GetFolder(objStartFolder)
Sub ShowSubFolders(Folder)
For Each Subfolder in Folder.SubFolders
Set objFolder = objFSO.GetFolder(Subfolder.Path)
Set colFiles = objFolder.Files
for each Files in colFiles
if LCase(InStr(1,Files, ".pdf")) > 1 then Wscript.Echo Files
next

An old question, but I'll answer anyway. The answer to the actual question asked is that the bare return is redundant and should be left out.
Furthermore, the suggested value is false for the following reason:
if (ret<0) return;
Redefining a C reserved word as a macro is a bad idea on the face of it, but this particular suggestion is simply unsupportable, both as an argument and as code.
<style name="Theme.IOSched" parent="android:style/Theme.Holo.Light">
<item name="android:windowBackground">@drawable/window_background</item>
<item name="android:actionBarStyle">@style/ActionBar</item>
</style>
you can not give your own color and backgroud in item windowBackground. give your color in your /color.xml file.
Assuming you are calling this in an Activity class
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);
The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).
Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.
Source: MSDN: Understanding Files and Filegroups
The recommended file name extension for secondary data files is .ndf
, but this is not enforced.

Chrome is preflighting the request to look for CORS headers. If the request is acceptable, it will then send the real request. If you're doing this cross-domain, you will simply have to deal with it or else find a way to make the request non-cross-domain. This is why the jQuery bug was closed as won't-fix. This is by design.
Unlike simple requests (discussed above), "preflighted" requests first send an HTTP request by the OPTIONS method to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data. In particular, a request is preflighted if:
- It uses methods other than GET, HEAD or POST. Also, if POST is used to send request data with a Content-Type other than application/x-www-form-urlencoded, multipart/form-data, or text/plain, e.g. if the POST request sends an XML payload to the server using application/xml or text/xml, then the request is preflighted.
- It sets custom headers in the request (e.g. the request uses a header such as X-PINGOTHER)
$tz = new DateTimeZone('Europe/London');
$date = new DateTime($today, $tz);
$date->modify('+10 hours');
// use $date->format() to outputs the result.
see DateTime Class (PHP 5 >= 5.2.0)
For the time being I am going a different route than I previous stated. I changed the way I am formatting the data to:
&A2168=1&A1837=5&A8472=1&A1987=2
On the server side I am using getParameterNames() to place all the keys into an Enumerator and then iterating over the Enumerator and placing the keys and values into a HashMap. It looks something like this:
Enumeration keys = request.getParameterNames();
HashMap map = new HashMap();
String key = null;
while(keys.hasMoreElements()){
key = keys.nextElement().toString();
map.put(key, request.getParameter(key));
}
If you already have a wheel file (.whl) on your pc, then just go with the following code:
cd ../user
pip install file.whl
If you want to download a file from web, and then install it, go with the following in command line:
pip install package_name
or, if you have the url:
pip install http//websiteurl.com/filename.whl
This will for sure install the required file.
Note: I had to type pip2 instead of pip while using Python 2.
If you are looking for a generic way of doing this via MySQL, you could simply use a SELECT
statement, and add the WHERE
clause to it.
This will grab all fields for all rows, where the date stored in field "date" is before "now".
SELECT * FROM table WHERE UNIX_TIMESTAMP(`date`) < UNIX_TIMESTAMP()
Personally, I found this method to be more gentle on newbies in MySQL, since it uses the standard SELECT statement with WHERE to fetch the results. Obviously, you could grab only the fields relevant if you wanted to, by listing them instead of using a wildcard (*).
I know that an answer has already been accepted, but one item to check is the encoding of the CSV file. I have a Powershell script that generates CSV files. By default, it was encoding them as UCS-2 Little Endian (per Notepad++). It would open the file in a single column in Excel and I'd have to do the Text to Columns conversion to split the columns. Changing the script to encode the same output as "ASCII" (UTF-8 w/o BOM per Notepad++) allowed me to open the CSV directly with the columns split out. You can change the encoding of the CSV in Notepad++ too.
From a comment:
I want to sort each set.
That's easy. For any set s
(or anything else iterable), sorted(s)
returns a list of the elements of s
in sorted order:
>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']
Note that sorted
is giving you a list
, not a set
. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2}
and {2, 1}
are the same set.
You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).
The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key
function:
>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']
For more information, see the Sorting HOWTO in the official docs.

Following Aristotle Pagaltzis and the idea of COALESCE
from Eric B’s answer, here it is an upsert option to update only few columns or insert full row if it does not exist.
In this case, imagine that title and content should be updated, keeping the other old values when existing and inserting supplied ones when name not found:
NOTE id
is forced to be NULL when INSERT
as it is supposed to be autoincrement. If it is just a generated primary key then COALESCE
can also be used (see Aristotle Pagaltzis comment).
WITH new (id, name, title, content, author)
AS ( VALUES(100, 'about', 'About this site', 'Whatever new content here', 42) )
INSERT OR REPLACE INTO page (id, name, title, content, author)
SELECT
old.id, COALESCE(old.name, new.name),
new.title, new.content,
COALESCE(old.author, new.author)
FROM new LEFT JOIN page AS old ON new.name = old.name;
So the general rule would be, if you want to keep old values, use COALESCE
, when you want to update values, use new.fieldname
You can't, but... If you own both pages then...
1) You can send the data via query params (http://siteB.com/?key=value)
2) You can create an iframe of Site B inside site A and you can send post messages from one place to the other. As Site B is the owner of site B cookies it will be able to set whatever value you need by processing the correct post message. (You should prevent other unwanted senders to send messages to you! that is up to you and the mechanism you decide to use to prevent that from happening)
You can use CSS to do it for example
<style>
html{
width:100%;
height:100%;
}
body{
width:100%;
height:100%;
background-color:#DDD;
}
</style>
Yield : will make thread to wait for the currently executing thread and the thread which has called yield() will attaches itself at the end of the thread execution. The thread which call yield() will be in Blocked state till its turn.
Sleep : will cause the thread to sleep in sleep mode for span of time mentioned in arguments.
Join : t1 and t2 are two threads , t2.join() is called then t1 enters into wait state until t2 completes execution. Then t1 will into runnable state then our specialist JVM thread scheduler will pick t1 based on criteria's.
Use QString's number method (docs are here):
double valueAsDouble = 1.2;
QString valueAsString = QString::number(valueAsDouble);
You can't.
So just don't apply styles directly like that, and apply a class "foo", and then define that in your CSS specification:
a.foo { color : orange; }
a.foo:hover { font-weight : bold; }
As many others have said, htmlentities()
will do the trick... but it will look like shit.
Wrap it up with a <pre>
tag and you'll preserve your indentation.
echo '<pre>';
echo htmlspecialchars($YOUR_HTML);
echo '</pre>';
I think you can try "Google Grid Gallery", it based on aforementioned Masonry with some additions, like styles and viewer.

From http://en.wikipedia.org/wiki/Byte-order_mark:
The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. Its code point is U+FEFF. BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.
Always using a BOM in your file will ensure that it always opens correctly in an editor which supports UTF-8 and BOM.
My real problem with the absence of BOM is the following. Suppose we've got a file which contains:
abc
Without BOM this opens as ANSI in most editors. So another user of this file opens it and appends some native characters, for example:
abg-aß?
Oops... Now the file is still in ANSI and guess what, "aß?" does not occupy 6 bytes, but 3. This is not UTF-8 and this causes other problems later on in the development chain.

Not least important is why these symbols occur in url. See https://www.php.net/manual/en/function.parse-str.php#76792, specifically:
parse_str('foo[]=1&foo[]=2&foo[]=3', $bar);
the above produces:
$bar = ['foo' => ['1', '2', '3'] ];

I've used the following script with great success on numerous servers:
pid=`jps -v | grep $INSTALLATION | awk '{print $1}'`
echo $INSTALLATION found at PID $pid
while [ -e /proc/$pid ]; do sleep 0.1; done
notes:
$INSTALLATION
contains enough of the process path that's it's totally unambiguousThis script is actually used to shut down a running instance of tomcat, which I want to shut down (and wait for) at the command line, so launching it as a child process simply isn't an option for me.
If you want all packages in that repository, use ...

As for your second problem:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python31\lib\pickle.py", line
1365, in load encoding=encoding,
errors=errors).load() EOFError
After you have read the contents of the file, the file pointer will be at the end of the file - there will be no further data to read. You have to rewind the file so that it will be read from the beginning again:
file.seek(0)
What you usually want to do though, is to use a context manager to open the file and read data from it. This way, the file will be automatically closed after the block finishes executing, which will also help you organize your file operations into meaningful chunks.
Finally, cPickle is a faster implementation of the pickle module in C. So:
In [1]: import _pickle as cPickle
In [2]: d = {"a": 1, "b": 2}
In [4]: with open(r"someobject.pickle", "wb") as output_file:
...: cPickle.dump(d, output_file)
...:
# pickle_file will be closed at this point, preventing your from accessing it any further
In [5]: with open(r"someobject.pickle", "rb") as input_file:
...: e = cPickle.load(input_file)
...:
In [7]: print e
------> print(e)
{'a': 1, 'b': 2}
Make sure that your sas.png
is marked as Build Action: Content
and Copy To Output Directory: Copy Always
in its Visual Studio Properties
...
I think the C# source code goes like this...
Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;
and XAML should be
<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0"
Name="image1" Stretch="Fill" VerticalAlignment="Top"
Source="../Bilder/sas.png"
Width="350" />
EDIT
Dynamically I think XAML would provide best way to load Images ...
<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
x:Name="MyImage"/>
where image.DataContext
is string
path.
MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";
public class MyImageSourceConverter : IValueConverter
{
public object Convert(object value_, Type targetType_,
object parameter_, System.Globalization.CultureInfo culture_)
{
return (new ImageSourceConverter()).ConvertFromString (value.ToString());
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Now as you set a different data context, Image
would be automatically loaded at runtime.
I had the same issue in my environment also (MacOS). I was using IntelliJ 2016. I had a Java library project (gradle).

So, for your case it would be:
std::getline(read,x);

Must add tho... this is generally bad practice, you shouldn't really be at the point where you start to need individual browser hacks to make you CSS work. Try using reset style sheets at the start of your project, to help avoid this.
Also, these hacks may not be future proof.
I came across the same error after updating to the latest version of JQuery. Therefore I updated the jquery file I was working on, as stated in a previous answer, so it said .on("load")
instead of .load()
.
This fix isn't very stable and sometimes it didn't work for me. Therefore to fix this issue you should update your code from:
.load();
to
.trigger("load");
I got this fix from the following source: https://github.com/stevenwanderski/bxslider-4/pull/1024
From w3schools.com: Made compatible with Firefox Sept, 2016
<input type="text" onfocusout="myFunction()">
I have used the same code block that have used in accepted answer , But it wont work as same in android 9 , So update the measure according to this
v.measure(MeasureSpec.makeMeasureSpec(parentView.getWidth(), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(parentView.getWidth(), MeasureSpec.AT_MOST));
How the constraint works bit different in android 9.
I ran into this same issue when using the Python MySQLdb module. Since MySQL will let you store just about any binary data you want in a text field regardless of character set, I found my solution here:
Using UTF8 with Python MySQLdb
Edit: Quote from the above URL to satisfy the request in the first comment...
"UnicodeEncodeError:'latin-1' codec can't encode character ..."
This is because MySQLdb normally tries to encode everythin to latin-1. This can be fixed by executing the following commands right after you've etablished the connection:
db.set_character_set('utf8')
dbc.execute('SET NAMES utf8;')
dbc.execute('SET CHARACTER SET utf8;')
dbc.execute('SET character_set_connection=utf8;')
"db" is the result of
MySQLdb.connect()
, and "dbc" is the result ofdb.cursor()
.
To specify a variable is an array of objects:
$needles = getAllNeedles();
/* @var $needles Needle[] */
$needles[1]->... //codehinting works
This works in Netbeans 7.2 (I'm using it)
Works also with:
$needles = getAllNeedles();
/* @var $needles Needle[] */
foreach ($needles as $needle) {
$needle->... //codehinting works
}
Therefore use of declaration inside the foreach
is not necessary.
First add in the head tags:
<script>
function showDialog(openFileDialog) {
document.getElementById(openFileDialog).click();
}
function fileName(openFileDialog) {
return document.getElementById(openFileDialog).value;
}
function hasFile(openFileDialog) {
return document.getElementById(openFileDialog).value != "";
}
function fileNameWithoutFakePath(openFileDialog) {
var fileName = document.getElementById(openFileDialog).value;
return fileName.substr(fileName.lastIndexOf('\\') + 1);
}
function fakePathWithoutFileName(openFileDialog) {
var fileName = document.getElementById(openFileDialog).value;
return fileName.substr(0, fileName.lastIndexOf('\\'));
}
</script>
if you already have script tags, just add these functions above.
In your body or form tags adding:
<input type="file" style="display:none" id="yourDesiredOrFavoriteNameForTheNewOpenFileDialogInstance"/>
No matter where in your html, is just like that you've created a new instance of type OpenFileDialog class as global variable, whose name is the id of the element, no matter where in your code or xaml, but in your script or code, you can't type his name, and then read a property or call a function, because there are global functions that do those that are not defined in the element input type="file". You just have to give these functions the id of the hidden input type="file" which is the name of the OpenFileDialog instance as string.
To ease your life in creating open file dialogs instances to your html, you can make a function that does it:
function createAndAddNewOpenFileDialog(name) {
document.getElementById("yourBodyOrFormId").innerHtml += "<input type='file' style='display:none' id='" + name + "'/>"
}
and if you want to remove open file dialog, then you can make and use the following function:
function removeOpenFileDialog(name) {
var html = document.getElementById("yourBodyOrFormId").innerHtml;
html = html.replace("<input type='file' style='display:none' id='" + name + "'/>", "");
document.getElementById("yourBodyOrFormId").innerHtml = html;
}
but before you remove open file dialog, ensure that it exists by making and using the following function:
function doesOpenFileDialogExist(name) {
return document.getElementById("yourBodyOrFormId").innerHtml.indexOf("<input type='file' style='display:none' id='" + name + "'/>") != -1
}
and if you don't want to create and add the open file dialogs in the body or form tags in the html, because this is adding hidden input type="file"s, then you can do it in script using the create function above:
function yourBodyOrFormId_onload() {
createAndAddNewOpenFileDialog("openFileDialog1");
createAndAddNewOpenFileDialog("openFileDialog2");
createAndAddNewOpenFileDialog("openFileDialog3");
createAndAddNewOpenFileDialog("File Upload");
createAndAddNewOpenFileDialog("Image Upload");
createAndAddNewOpenFileDialog("bla");
//etc and rest of your code
}
Ensure that near your body or form tags, you added:
onload="yourBodyOrFormId_onload()"
You don't have to do this line above, if you did it already.
TIP: You can add to your project or website new JScript File, if you don't have yet, and in this file you can put all the open file dialog functions away from the script tags and the html or web form page, and use them in your html or web form page from this JScript file, but don't forget before to link the html or web form page to the JScript File of course. You can do it just by dragging the JScript file to your html page in the head tags. If your page is web form and not simple html, and you don't have head tags, then put it anywhere so that it can work. Don't forget to define global variable in that JScript File, whose value will be your body or form id as string. After you linked the JScript file to your html or web form page, you can onload event of your body of form, set the value of that variable to your body or form id. Then in the JScript File, you don't have to give to the document the id of the body or form of one page anymore, just give it the value of that variable. You can call that variable bodyId or formId or bodyOrFormId or any other name you want.
Good luck man!

Tested in MySQL 8.x both in Windows and Linux.
I had a similar proxy related problem. In my case it was enough to add:
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain");
It's almost the same in MySQL, but you have to use the table alias right after the word "DELETE":
DELETE a
FROM TableA AS a
INNER JOIN TableB AS b
ON a.BId = b.BId

Code for adding fragment
public Fragment getItem(int position) {
switch (position){
case 0:
return new Fragment1();
case 1:
return new Fragment2();
case 2:
return new Fragment3();
case 3:
return new Fragment4();
default:
break;
}
return null;
}
Create an xml file for each fragment say for Fragment1, use fragment_one.xml as layout file, use the below code in Fragment1 java file.
public class Fragment1 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_one, container, false);
return view;
}
}
Later you can make necessary corrections.. It worked for me.
Use some preprocessor macro to check if it's in windows or linux. For example
#ifdef WIN32
LIB=
#elif __GNUC__
LIB=wsock32
#endif
include -l$(LIB) in you build command.
You can also specify some command line argument to differentiate both.
You can in fact have multiple statements in a lambda expression in python. It is not entirely trivial but in your example, the following works:
map(lambda x: x.sort() or x[1],lst)
You have to make sure that each statement does not return anything or if it does wrap it in (.. and False). The result is what is returned by the last evaluation.
Example:
>>> f = (lambda : (print(1) and False) or (print(2) and False) or (print(3) and False))
>>> f()

Lift-json is at version 2.6 and it works really well (and is also very well supported, the maintainer is always ready to fix any bugs users may find. You can find examples using it on the github repository
The maintainer (Joni Freeman) is always reachable on the Lift mailing list. There are also other users on the mailing list who are very helpful as well.
As @Alexey points out, if you want to use the library with other Scala version, say 2.11.x
, change scalaVersion
and use %%
as follows:
scalaVersion := "2.11.5"
"net.liftweb" %% "lift-json" % "2.6"
You can check the liftweb.net site to find out the latest version as time goes by.
You can use javax.xml.bind.DatatypeConverter
class
DatatypeConverter.printDateTime
&
DatatypeConverter.parseDateTime
You can never instantiate an interface in java. You can, however, refer to an object that implements an interface by the type of the interface. For example,
public interface A
{
}
public class B implements A
{
}
public static void main(String[] args)
{
A test = new B();
//A test = new A(); // wont compile
}
What you did above was create an Anonymous class that implements the interface. You are creating an Anonymous object, not an object of type interface Test
.

In case you want to pass in a block, say, for a glyphicon button, as in the following:
<%= link_to my_url, class: "stuff" do %>
<i class="glyphicon glyphicon-inbox></i> Nice glyph-button

Then passing querystrings params could be accomplished through:
<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
<i class="glyphicon glyphicon-inbox></i> Nice glyph-button

MySQL doesn't support multi-table insertion in a single INSERT statement. Oracle is the only one I'm aware of that does, oddly...
INSERT INTO NAMES VALUES(...)
INSERT INTO PHONES VALUES(...)
Whenever I talk managed vs. unmanaged performance, I like to point to the series Rico (and Raymond) did comparing C++ and C# versions of a Chinese/English dictionary. This google search will let you read for yourself, but I like Rico's summary.
So am I ashamed by my crushing defeat? Hardly. The managed code got a very good result for hardly any effort. To defeat the managed Raymond had to:
- Write his own file I/O stuff
- Write his own string class
- Write his own allocator
- Write his own international mapping
Of course he used available lower level libraries to do this, but that's still a lot of work. Can you call what's left an STL program? I don't think so, I think he kept the std::vector class which ultimately was never a problem and he kept the find function. Pretty much everything else is gone.
So, yup, you can definately beat the CLR. Raymond can make his program go even faster I think.
Interestingly, the time to parse the file as reported by both programs internal timers is about the same -- 30ms for each. The difference is in the overhead.
For me the bottom line is that it took 6 revisions for the unmanaged version to beat the managed version that was a simple port of the original unmanaged code. If you need every last bit of performance (and have the time and expertise to get it), you'll have to go unmanaged, but for me, I'll take the order of magnitude advantage I have on the first versions over the 33% I gain if I try 6 times.
Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:
#container {
min-width:800px;
width: auto !important;
width:800px;
}
That will effectively give you 800px min-width in IE6 and any up-to-date browsers.
There are basically two things that can happen here.
Console output It is possible for a winforms program to attach itself to the console window that created it (or to a different console window, or indeed to a new console window if desired). Once attached to the console window Console.WriteLine() etc works as expected. One gotcha to this approach is that the program returns control to the console window immediately, and then carries on writing to it, so the user can also type away in the console window. You can use start with the /wait parameter to handle this I think.
Redirected console output This is when someone pipes the output from your program somewhere else, eg.
yourapp > file.txt
Attaching to a console window in this case effectively ignores the piping. To make this work you can call Console.OpenStandardOutput() to get a handle to the stream that the output should be piped to. This only works if the output is piped, so if you want to handle both of the scenarios you need to open the standard output and write to it and attach to the console window. This does mean that the output is sent to the console window and to the pipe but its the best solution I could find. Below the code I use to do this.
// This always writes to the parent console window and also to a redirected stdout if there is one.
// It would be better to do the relevant thing (eg write to the redirected file if there is one, otherwise
// write to the console) but it doesn't seem possible.
public class GUIConsoleWriter : IConsoleWriter
{
[System.Runtime.InteropServices.DllImport("kernel32.dll")]
private static extern bool AttachConsole(int dwProcessId);
private const int ATTACH_PARENT_PROCESS = -1;
StreamWriter _stdOutWriter;
// this must be called early in the program
public GUIConsoleWriter()
{
// this needs to happen before attachconsole.
// If the output is not redirected we still get a valid stream but it doesn't appear to write anywhere
// I guess it probably does write somewhere, but nowhere I can find out about
var stdout = Console.OpenStandardOutput();
_stdOutWriter = new StreamWriter(stdout);
_stdOutWriter.AutoFlush = true;
AttachConsole(ATTACH_PARENT_PROCESS);
}
public void WriteLine(string line)
{
_stdOutWriter.WriteLine(line);
Console.WriteLine(line);
}
}
for who looks for more options here is a one

Generates a strong password of length 8 containing at least one lower case letter, one uppercase letter, one digit, and one special character. You can change the length in the code too.
function checkForCharacterCondition($string) {
return (bool) preg_match('/(?=.*([A-Z]))(?=.*([a-z]))(?=.*([0-9]))(?=.*([~`\!@#\$%\^&\*\(\)_\{\}\[\]]))/', $string);

function generate_pass() {
global $j;
$allowedCharacters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ~`!@#$%^&*()_{}[]';
$pass = '';
$length = 8;
$max = mb_strlen($allowedCharacters, '8bit') - 1;
for ($i = 0; $i < $length; ++$i) {
$pass .= $allowedCharacters[random_int(0, $max)];
}
if (checkForCharacterCondition($pass)){
return '<br><strong>Selected password: </strong>'.$pass;

from statistics import mean
avarage=mean(your_list)
for example
from statistics import mean
my_list=[5,2,3,2]
avarage=mean(my_list)
print(avarage)
and result is
3.0
Here's a simple way to test it:
public class OperatorTest {
public static void main(String[] args) {
boolean a = false;
a &= b();
}
private static boolean b() {
System.out.println("b() was called");
return true;
}
}
The output is b() was called
, therefore the right-hand operand is evaluated.
So, as already mentioned by others, a &= b
is the same as a = a & b
.
In computer networking, localhost (meaning "this computer") is the standard hostname given to the address of the loopback network interface.
Localhost always translates to the loopback IP address 127.0.0.1 in IPv4.
It is also used instead of the hostname of a computer. For example, directing a web browser installed on a system running an HTTP server to http://localhost will display the home page of the local web site.
Source: Wikipedia - Localhost.
The :80
part is the TCP port. You can consider these ports as communications endpoints on a particular IP address (in the case of localhost - 127.0.0.1). The IANA is responsible for maintaining the official assignments of standard port numbers for specific services. Port 80 happens to be the standard port for HTTP.

On Windows you can include the windows library and use "Sleep(0);" to sleep the program. It takes a value that represents milliseconds.
I m using Tablayout with ViewPagerAdapter. For passing data between fragments or for communicating between fragments use below code which works perfectly fine and refresh the fragment when ever it appears. Inside button click of second fragment write below code.
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text=e1.getText().toString(); // get the text from EditText
// move from one fragment to another fragment on button click
TabLayout tablayout = (TabLayout) getActivity().findViewById(R.id.tab_layout); // here tab_layout is the id of TabLayout which is there in parent Activity/Fragment
if (tablayout.getTabAt(1).isSelected()) { // here 1 is the index number of second fragment i-e current Fragment
LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(getContext());
Intent i = new Intent("EDIT_TAG_REFRESH");
i.putExtra("MyTextValue",text);
lbm.sendBroadcast(i);
}
tablayout.getTabAt(0).select(); // here 0 is the index number of first fragment i-e to which fragment it has to moeve
}
});
below is the code which has to be written in first fragment (in my case) i-e in receiving Fragment.
MyReceiver r;
Context context;
String newValue;
public void refresh() {
//your code in refresh.
Log.i("Refresh", "YES");
}
public void onPause() {
super.onPause();
LocalBroadcastManager.getInstance(context).unregisterReceiver(r);
}
public void onResume() {
super.onResume();
r = new MyReceiver();
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(r,
new IntentFilter("EDIT_TAG_REFRESH"));
} // this code has to be written before onCreateview()
// below code can be written any where in the fragment
private class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
PostRequestFragment.this.refresh();
String action = intent.getAction();
newValue=intent.getStringExtra("MyTextValue");
t1.setText(newValue); // upon Referesh set the text
}
}
Well, you're on the right path, Benno!
There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True
End If
End If
End If
End Sub
Use for of loop instead which is part of ES2015 release. Unlike forEach, we can use return, break and continue. See https://hacks.mozilla.org/2015/04/es6-in-depth-iterators-and-the-for-of-loop/
let arr = [1,2,3,4,5];
for (let ele of arr) {
if (ele > 3) break;
console.log(ele);

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.
If you have accidentally removed DLL file from php/ext
folder, just add it back (get the copy from XAMPP zip archive - its downloadable).
If you have deleted the accompanying INI configuration line from php.ini
file, add it back as well:
extension=php_mbstring.dll
Also, ensure to restart your webserver (Apache) using XAMPP control panel.

I think you might want:
String encodedFile = Base64.getEncoder().encodeToString(bytes);
Convert string to Byte-Array:
byte[] theByteArray = stringToConvert.getBytes();
Convert String to Byte:
String str = "aa";
byte b = Byte.valueOf(str);
The following may help give you want you need:
SELECT
index_owner, index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
ORDER BY
index_owner,
table_name,
index_name,
column_position
;
For my use case, I wanted the column_names and order that they are in the indices (so that I could recreate them in a different database engine after migrating to AWS). The following was what I used, in case it is of use to anyone else:
SELECT
index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
WHERE
INDEX_OWNER = 'FOO'
AND TABLE_NAME NOT LIKE '%$%'
ORDER BY
table_name,
index_name,

If you use Flutter, then you can access it via people.googleapis.com
endpoint, code uses google_sign_in
library
import 'package:google_sign_in/google_sign_in.dart';
Future<String> getPhotoUrl(GoogleSignInAccount account, String userId) async {
// final authentication = await account.authentication;
final url = 'https://people.googleapis.com/v1/people/${userId}?personFields=photos';
final response = await http.get(
url,
headers: await account.authHeaders
);
final data = json.decode(response.body);
return data['photos'].first['url'];
}
You will get something like
{
resourceName: people/998812322529259873423,
etag: %EgQBAzcabcQBAgUH,
photos: [{metadata: {primary: true, source: {type: PROFILE, id: 107721622529987673423}},
url: https://lh3.googleusercontent.com/a-/abcdefmB2p1VWxLsNT9WSV0yqwuwo6o2Ba21sh_ra7CnrZ=s100}]
}
where url
is an accessible image url.

I like to use rails-settings for global configuration values that need to be changeable via web interface.
you can even create a function to return different time stamps depending on your necessity:
func dataatual(_ tipo:Int) -> String {
let date = Date()
let formatter = DateFormatter()
if tipo == 1{
formatter.dateFormat = "dd/MM/yyyy"
} else if tipo == 2{
formatter.dateFormat = "yyyy-MM-dd HH:mm"
} else {
formatter.dateFormat = "dd-MM-yyyy"
}
return formatter.string(from: date)
}
You have the right idea, except a more precise timing is available with the microtime() function.
If what is inside the loop is fast, it is possible that the apparent elapsed time will be zero. If so, wrap another loop around the code and call it repeatedly. Be sure to divide the difference by the number of iterations to get a per-once time. I have profiled code which required 10,000,000 iterations to get consistent, reliable timing results.
Iterate over a copy instead, such as the one returned by items()
:
for k, v in list(mydict.items()):
In simple, using Comparator and Collection you can sort like below in reversal order using JAVA 8
import java.util.Comparator;;

.collect(Collectors.toList());
Simply use the intValue method of Double
Double initialValue = 7.12;
int finalValue = initialValue.intValue();

Between int32
and int32_t
, (and likewise between int8
and int8_t
) the difference is pretty simple: the C standard defines int8_t
and int32_t
, but does not define anything named int8
or int32
-- the latter (if they exist at all) is probably from some other header or library (most likely predates the addition of int8_t
and int32_t
in C99).
Plain int
is quite a bit different from the others. Where int8_t
and int32_t
each have a specified size, int
can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits).
On the other hand, int
is guaranteed to be present in every implementation of C, where int8_t
and int32_t
are not. It's probably open to question whether this matters to you though. If you use C on small embedded systems and/or older compilers, it may be a problem. If you use it primarily with a modern compiler on desktop/server machines, it probably won't be.
Oops -- missed the part about char
. You'd use int8_t
instead of char if (and only if) you want an integer type guaranteed to be exactly 8 bits in size. If you want to store characters, you probably want to use char
instead. Its size can vary (in terms of number of bits) but it's guaranteed to be exactly one byte. One slight oddity though: there's no guarantee about whether a plain char
is signed or unsigned (and many compilers can make it either one, depending on a compile-time flag). If you need to ensure its being either signed or unsigned, you need to specify that explicitly.
If the set of possibilities is "compact" (i.e. largest-value - smallest-value is, say, less than 200) you might consider a lookup table. This would be especially useful if you had a structure like
if (x == 12 || x == 16 || x == 19 || ...)
else if (x==34 || x == 55 || ...)
else if (...)
Set up an array with values identifying the branch to be taken (1, 2, 3 in the example above) and then your tests become
switch(dispatchTable[x])
{
case 1:
...
break;
case 2:
...
break;
case 3:
...
break;
}
Whether or not this is appropriate depends on the semantics of the problem.
If an array isn't appropriate, you could use a Map<Integer,Integer>
, or if you just want to test membership for a single statement, a Set<Integer>
would do. That's a lot of firepower for a simple if
statement, however, so without more context it's kind of hard to guide you in the right direction.
Earlier,I was facing problem in using jquery with React js,so I did following steps to make it working-
npm install jquery --save
Then, import $ from "jquery";
You can also pad a string to the required length using Guava's Strings.padEnd(String input, int minLength, char padding)
This is the best way, I know of to create dynamic variables in python.
my_dict = {}
x = "Buffalo"
my_dict[x] = 4
I found a similar, but not the same question here Creating dynamically named variables from user input
import java.lang.String;
This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).
Take a look here.
You should set the font of the button's titleLabel instead.
myButton.titleLabel!.font = UIFont(name: "...", 10)
I was searching an answer for this same question and found ENTRYPOINT in Dockerfile solution for me.
Dockerfile
...
ENTRYPOINT /my-script.sh ; /my-script2.sh ; /bin/bash
Now the scripts are executed when I start the container and I get the bash prompt after the scripts has been executed.
\r
can do the work here for you.
The \includegraphics
function has a page
option for inserting a specific page of a PDF file as graphs. The default is one, but you can change it.
\includegraphics[scale=0.75,page=2]{multipage.pdf}

Per this blog post, you can add css classes to your fields using a custom template filter.
from django import template
register = template.Library()
@register.filter(name='addcss')
def addcss(field, css):
return field.as_widget(attrs={"class":css})
Put this in your app's templatetags/ folder and you can now do
{{field|addcss:"form-control"}}
The accepted answer didn't work with my table (thousands of rows, dynamic loading) but the code below works:
- (void)scrollToBottom:(id)sender {
if ([self.sections count] > 0) {
NSInteger idx = [self.sections count] - 1;
CGRect sectionRect = [self.tableView rectForSection:idx];
sectionRect.size.height = self.tableView.frame.size.height;
[self.tableView scrollRectToVisible:sectionRect animated:NO];
}
}
My solution was uninstalling and installing the PHP instance (7.0 in my case) again:
sudo apt-get purge php7.0
sudo apt-get install php7.0
After that you will need to restart the Apache service:
sudo service apache2 restart
Finally, verify again in your browser with your localhost or IP address.
Add above code in API gateway under GET-Integration Request> mapping section.
You can use the following class. Just change zero to any default value you like. The solution was tested in Python 2.7.
class cDefaultDict(dict):
# dictionary that returns zero for missing keys
# keys with zero values are not stored
def __missing__(self,key):
return 0
def __setitem__(self, key, value):
if value==0:
if key in self: # returns zero anyway, so no need to store it
del self[key]
else:
dict.__setitem__(self, key, value)
This should solve your problem:
select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);
Give a look also as this SQL Fiddle for test.
I would add one more thing to Marc's answer: The memberOf attribute can't contain wildcards, so you can't say something like "memberof=CN=SPS*", and expect it to find all groups that start with "SPS".

One difference is that interfaces create a new name that is used everywhere. Type aliases don’t create a new name — for instance, error messages won’t use the alias name.
From ggplot2 2.0.0
you can use the margin =
argument of element_text()
to change the distance between the axis title and the numbers. Set the values of the margin
on t
op, r
ight, b
ottom, and l
eft side of the element.
ggplot(mpg, aes(cty, hwy)) + geom_point()+
theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))
margin
can also be used for other element_text
elements (see ?theme
), such as axis.text.x
, axis.text.y
and title
.
addition
in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top")
, you'll need a different theme setting - e.g. axis.title.x.top
. See https://github.com/tidyverse/ggplot2/issues/4343.
I had the same issue with Oracle.DataAccess.dll v4.121.2.0. with 2- homes installation (32 and 64 bit versions). 32-bit version workerd, 64-bit version didn't.
In my case (after 2 days of trying) I found that the problem was permissions on the 64-bit-home version. Many Directories in that version had exclusively overridden permissions where "Authenticated Users" role did not have "Read" access, which is set by default on the parent directory. Those sub-directories included "bin", "network/admin", "nls", "oracore", "RDBMS" and possibly others. I found them by filtering out "ACCESS DENIED" result in "Process Monitor" (Procmon.exe) utility from sysinternals. Once the permissions were inherited from the parent directory to those child subdirectories everything started to work.
I didn't what to override the permissions on the whole oracle home so I did them one directory at a time, but I guess if you don't worry about security so much you can reset it on the whole corresponding oracle home directory.
I had the same problem today. I've found this link, where you can try 3 solutions. First solution helped for me.
Two ways
1)instantiate the first class
and getter for arrayList
or
2)Make arraylist as static
And finally
Use document.scrollTop
to change the position of the document. Set the scrollTop
of the document
equal to the bottom
of the featured section of your site
The solution provided by BBoy works fine. But in my case I had to use
e.Graphics.DrawImage(memoryImage, e.PageBounds);
This will print only the form. When I use MarginBounds it prints the entire screen even if the form is smaller than the monitor screen. PageBounds solved that issue. Thanks to BBoy!
This happens generally when you try access another domain's resources.
This is a security feature for avoiding everyone freely accessing any resources of that domain (which can be accessed for example to have an exact same copy of your website on a pirate domain).
The header of the response, even if it's 200OK do not allow other origins (domains, port) to access the ressources.
You can fix this problem if you are the owner of both domains:
To change that, you can write this in the .htaccess of the requested domain file:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
If you only want to give access to one domain, the .htaccess should look like this:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin 'https://my-domain.tdl'
</IfModule>
If you set this into the response header of the requested file, you will allow everyone to access the ressources:
Access-Control-Allow-Origin : *
OR
Access-Control-Allow-Origin : http://www.my-domain.com
Peace and code ;)
I guess you want to get number(s) from the string. In which case, you can use the following:
// Returns an array of numbers located in the string
function get_numbers(input) {
return input.match(/[0-9]+/g);
}
var first_test = get_numbers('something102');
var second_test = get_numbers('something102or12');
var third_test = get_numbers('no numbers here!');
alert(first_test); // [102]
alert(second_test); // [102,12]
alert(third_test); // null
For startswith, you can use indexOf:
if(str.indexOf('Hello') == 0) {
...
and you can do the maths based on string length to determine 'endswith'.
if(str.lastIndexOf('Hello') == str.length - 'Hello'.length) {
You should set property file name without .properties
extension,
it works correctly for me:)
MVC (Model View Controller)
The input is directed at the Controller first, not the view. That input might be coming from a user interacting with a page, but it could also be from simply entering a specific url into a browser. In either case, its a Controller that is interfaced with to kick off some functionality. There is a many-to-one relationship between the Controller and the View. That’s because a single controller may select different views to be rendered based on the operation being executed. Note the one way arrow from Controller to View. This is because the View doesn’t have any knowledge of or reference to the controller. The Controller does pass back the Model, so there is knowledge between the View and the expected Model being passed into it, but not the Controller serving it up.
MVP (Model View Presenter)
The input begins with the View, not the Presenter. There is a one-to-one mapping between the View and the associated Presenter. The View holds a reference to the Presenter. The Presenter is also reacting to events being triggered from the View, so its aware of the View its associated with. The Presenter updates the View based on the requested actions it performs on the Model, but the View is not Model aware.
For more Reference
It's not the best answer, but its also an option: since you can concatenate multiple expressions, but just the last one is rendered, you can finish your expression with ""
and your variable will be hidden.
So, you could define the variable with:
{{f = forecast[day.iso]; ""}}
I answer to myself. As suggested by Vadzim, I must consider the jboss-logging.xml file and insert these lines:
<logger category="org.hibernate">
<level name="TRACE"/>
</logger>
Instead of DEBUG level I wrote TRACE. Now don't look only the console but open the server.log file (debug messages aren't sent to the console but you can configure this mode!).
I woudl say:
This give 2 major advantages:
I don't think it's more expensive to use keys over each, so no need for two different constructs for the same thing in your code.
document.getElementById('drpSelectSourceLibrary').value = 'Seven';
I decided to download the assigned port numbers from IANA, filter out the used ports, and sort each "Unassigned" range in order of most ports available, descending. This did not work, since the csv file has ranges marked as "Unassigned" that overlap other port number reservations. I manually expanded the ranges of assigned port numbers, leaving me with a list of all assigned port numbers. I then sorted that list and generated my own list of unassigned ranges.
Since this stackoverflow.com page ranked very high in my search about the topic, I figured I'd post the largest ranges here for anyone else who is interested. These are for both TCP and UDP where the number of ports in the range is at least 500.

This is on groovy, but I thing that this is not problem for you. Method work perfect.
My scenario is when the user strikes the enter key while typing in textarea i have to include a line break.I achieved this using the below code......Hope it may helps somebody......
function CheckLength()
{
var keyCode = event.keyCode
if (keyCode == 13)

}
0 values of basic types (1)(2)map to false
.
Other values map to true
.
This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.
It's a common error to assume that as function return values, false
indicates failure. But in particular from main
it's false
that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.
There's no need to cast to bool
for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x
, works nicely. One can read !!
as a “convert to bool
” operator, much as -->
can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)
1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false
; any other value is converted to true
. For direct-initialization (8.5), a prvalue of type std::nullptr_t
can be converted to a prvalue of type bool
; the resulting value is false
.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool
, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”

Unlike RDDs
Spark Dataset
(including Dataset[Row]
a.k.a DataFrame
) cannot use custom partitioner as for now. You can typically address that by creating an artificial partitioning column but it won't give you the same flexibility.
One thing you can do is to pre-partition input data before you create a DataFrame
import org.apache.spark.sql.types._
import org.apache.spark.sql.Row
import org.apache.spark.HashPartitioner
val schema = StructType(Seq(
StructField("x", StringType, false),
StructField("y", LongType, false),
StructField("z", DoubleType, false)
))
val rdd = sc.parallelize(Seq(
Row("foo", 1L, 0.5), Row("bar", 0L, 0.0), Row("??", -1L, 2.0),
Row("foo", -1L, 0.0), Row("??", 3L, 0.6), Row("bar", -3L, 0.99)
))
val partitioner = new HashPartitioner(5)
val partitioned = rdd.map(r => (r.getString(0), r))
.partitionBy(partitioner)
.values
val df = sqlContext.createDataFrame(partitioned, schema)
Since DataFrame
creation from an RDD
requires only a simple map phase existing partition layout should be preserved*:
assert(df.rdd.partitions == partitioned.partitions)
The same way you can repartition existing DataFrame
:
sqlContext.createDataFrame(
df.rdd.map(r => (r.getInt(1), r)).partitionBy(partitioner).values,
df.schema
)
So it looks like it is not impossible. The question remains if it make sense at all. I will argue that most of the time it doesn't:
Repartitioning is an expensive process. In a typical scenario most of the data has to be serialized, shuffled and deserialized. From the other hand number of operations which can benefit from a pre-partitioned data is relatively small and is further limited if internal API is not designed to leverage this property.
GROUP BY
- it is possible to reduce memory footprint of the temporary buffers**, but overall cost is much higher. More or less equivalent to groupByKey.mapValues(_.reduce)
(current behavior) vs reduceByKey
(pre-partitioning). Unlikely to be useful in practice.SqlContext.cacheTable
. Since it looks like it is using run length encoding, applying OrderedRDDFunctions.repartitionAndSortWithinPartitions
could improve compression ratio. Performance is highly dependent on a distribution of the keys. If it is skewed it will result in a suboptimal resource utilization. In the worst case scenario it will be impossible to finish the job at all.
Partitioning with JDBC sources:
JDBC data sources support predicates
argument. It can be used as follows:
sqlContext.read.jdbc(url, table, Array("foo = 1", "foo = 3"), props)
It creates a single JDBC partition per predicate. Keep in mind that if sets created using individual predicates are not disjoint you'll see duplicates in the resulting table.
partitionBy
method in DataFrameWriter
:
Spark DataFrameWriter
provides partitionBy
method which can be used to "partition" data on write. It separates data on write using provided set of columns
val df = Seq(
("foo", 1.0), ("bar", 2.0), ("foo", 1.5), ("bar", 2.6)
).toDF("k", "v")
df.write.partitionBy("k").json("/tmp/foo.json")
This enables predicate push down on read for queries based on key:
val df1 = sqlContext.read.schema(df.schema).json("/tmp/foo.json")
df1.where($"k" === "bar")
but it is not equivalent to DataFrame.repartition
. In particular aggregations like:
val cnts = df1.groupBy($"k").sum()
will still require TungstenExchange
:
cnts.explain
// == Physical Plan ==
// TungstenAggregate(key=[k#90], functions=[(sum(v#91),mode=Final,isDistinct=false)], output=[k#90,sum(v)#93])
// +- TungstenExchange hashpartitioning(k#90,200), None
// +- TungstenAggregate(key=[k#90], functions=[(sum(v#91),mode=Partial,isDistinct=false)], output=[k#90,sum#99])
// +- Scan JSONRelation[k#90,v#91] InputPaths: file:/tmp/foo.json
bucketBy
method in DataFrameWriter
(Spark >= 2.0):
bucketBy
has similar applications as partitionBy
but it is available only for tables (saveAsTable
). Bucketing information can used to optimize joins:
// Temporarily disable broadcast joins
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", -1)
df.write.bucketBy(42, "k").saveAsTable("df1")
val df2 = Seq(("A", -1.0), ("B", 2.0)).toDF("k", "v2")
df2.write.bucketBy(42, "k").saveAsTable("df2")
// == Physical Plan ==
// *Project [k#41, v#42, v2#47]
// +- *SortMergeJoin [k#41], [k#46], Inner
// :- *Sort [k#41 ASC NULLS FIRST], false, 0
// : +- *Project [k#41, v#42]
// : +- *Filter isnotnull(k#41)
// : +- *FileScan parquet default.df1[k#41,v#42] Batched: true, Format: Parquet, Location: InMemoryFileIndex[file:/spark-warehouse/df1], PartitionFilters: [], PushedFilters: [IsNotNull(k)], ReadSchema: struct<k:string,v:int>
// +- *Sort [k#46 ASC NULLS FIRST], false, 0

// +- *Filter isnotnull(k#46)

* By partition layout I mean only a data distribution. partitioned
RDD has no longer a partitioner.
** Assuming no early projection. If aggregation covers only small subset of columns there is probably no gain whatsoever.
How about:
String.prototype.strcmp = function(s) {
if (this < s) return -1;
if (this > s) return 1;
return 0;
}
Then, to compare s1 with 2:
s1.strcmp(s2)
use NestedScrollView
with viewport true is working good for me
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="700dp">
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>
on tables with many rows are two queries probably faster...
SELECT @last_id := MAX(id) FROM table;
SELECT * FROM table WHERE id = @last_id;
Another solution within a query :
select
Id,
STUFF(
(select (', "' + od.ProductName + '"')
from OrderDetails od (nolock)
where od.Order_Id = o.Id
order by od.ProductName
FOR XML PATH('')), 1, 2, ''
) ProductNames
from Orders o (nolock)
where o.Customer_Id = 525188
order by o.Id desc
(EDIT: thanks @user007 for the STUFF declaration)
One can also use slightly modified version of the accepted one and adjust base characters string to it's needs:
public static string Int32ToString(int value, int toBase)
{
string result = string.Empty;
do
{
result = "0123456789ABCDEF"[value % toBase] + result;
value /= toBase;
}
while (value > 0);
return result;
}

Before we try to solve the invalid character problem, the lack of curly braces around the if
and else if
statements is wreaking havoc on your program's logic. Change it to this:
if (personPlay.equals(computerPlay)) {
System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
if (computerPlay.equals("S"))
System.out.println("Rock crushes scissors. You win!!");
else if (computerPlay.equals("P"))
System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
if (computerPlay.equals("S"))
System.out.println("Scissor cuts paper. You lose!!");
else if (computerPlay.equals("R"))
System.out.println("Paper eats rock. You win!!");
}
else if (personPlay.equals("S")) {
if (computerPlay.equals("P"))
System.out.println("Scissor cuts paper. You win!!");
else if (computerPlay.equals("R"))
System.out.println("Rock breaks scissors. You lose!!");
}
else
System.out.println("Invalid user input.");
Much clearer! It's now actually a piece of cake to catch the bad characters. You need to move the else
statement to somewhere that will catch the errors before you attempt to process anything else. So change everything to:
if( /* insert your check for bad characters here */ ) {
System.out.println("Invalid user input.");
}
else if (personPlay.equals(computerPlay)) {
System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
if (computerPlay.equals("S"))
System.out.println("Rock crushes scissors. You win!!");
else if (computerPlay.equals("P"))
System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
if (computerPlay.equals("S"))
System.out.println("Scissor cuts paper. You lose!!");
else if (computerPlay.equals("R"))
System.out.println("Paper eats rock. You win!!");
}
else if (personPlay.equals("S")) {
if (computerPlay.equals("P"))
System.out.println("Scissor cuts paper. You win!!");
else if (computerPlay.equals("R"))
System.out.println("Rock breaks scissors. You lose!!");
}
please set dataType config property in your ajax call and give it another try!
another point is you are using ajax call setup configuration properties as string and it is wrong as reference site
$.ajax({
url : 'http://voicebunny.comeze.com/index.php',
type : 'GET',
data : {
'numberOfWords' : 10
},
dataType:'json',
success : function(data) {
alert('Data: '+data);
},
error : function(request,error)
{
alert("Request: "+JSON.stringify(request));
}
});
I hope be helpful!
Yes what everybody says above.
For your immediate situation, instead of onChange, you can use onInput, new in html5. The input event is the same, but it'll fire upon every keystroke, regardless of the focus. Also works on selects and all the rest just like onChange.
This is a late answer, but by looking at the source code, I noticed that when the video is fullscreen, the "mejs-container-fullscreen" class is added to the "mejs-container" element. It is thus possible to change the styling based on this class.
.mejs-container.mejs-container-fullscreen {
// This rule applies only to the container when in fullscreen
padding-top: 57%;
}
Also, if you wish to make your MediaElement video fluid using CSS, below is a great trick by Chris Coyier: http://css-tricks.com/rundown-of-handling-flexible-media/
Just add this to your CSS:
.mejs-container {
width: 100% !important;
height: auto !important;
padding-top: 57%;
}
.mejs-overlay, .mejs-poster {
width: 100% !important;
height: 100% !important;
}
.mejs-mediaelement video {
position: absolute;
top: 0; left: 0; right: 0; bottom: 0;
width: 100% !important;
height: 100% !important;
}
I hope it helps.
Simple solution that works:
yarn test -g fileName
or
npm test -g fileName
Example:
yarn test -g cancelTransaction
or
npm test -g cancelTransaction
More about test filters:
Test Filters
--fgrep, -f Only run tests containing this string [string]
--grep, -g Only run tests matching this string or regexp [string]
--invert, -i Inverts --grep and --fgrep matches [boolean]
def nested1(num1):
print "nested1 has",num1
def nested2(num2):
print "nested2 has",num2,"and it can reach to",num1
return num1+num2 #num1 referenced for reading here
return nested2
Gives:
In [17]: my_func=nested1(8)
nested1 has 8
In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13
This is an example of what a closure is and how it can be used.
You can just use the attribute selector and then test the length:
$('input[readonly]').length == 0 // --> ok
$('input[readonly]').length > 0 // --> not ok
On Ubuntu you can simply add the most recent Apt repository and then run:
sudo apt-get install postgresql-client-11
It works and there's even a common pattern for your approach: the Adapter pattern. But of course, (1) it does not work for casting java primitives to objects and (2) the class has to be adaptable (usually by implementing a custom interface).
With this pattern you could do something like:
Wolf bigBadWolf = new Wolf();
Sheep sheep = (Sheep) bigBadWolf.getAdapter(Sheep.class);
and the getAdapter method in Wolf class:
public Object getAdapter(Class clazz) {
if (clazz.equals(Sheep.class)) {
// return a Sheep implementation
return getWolfDressedAsSheep(this);
}
if (clazz.equals(String.class)) {
// return a String
return this.getName();
}
return null; // not adaptable
}
For you special idea - that is impossible. You can't use a String value for casting.
I dont think anyone has answered the question correctly.So, for anyone else who has the same question, this should help :
Step 1 Go to Build>Generate Signed APK>Next (module selected would be your module , most often called "app")
Step 2 Click on create new
Step 3 Basically, fill in the form with the required details. The confusing bit it is where it asks for a Key Store Path. Click on the icon on the right with the 3 dots ("..."), which will open up a navigator window asking you to navigate and select a .jks file.Navigate to a folder where you want your keystore file saved and then at the File Name box at the bottom of that window, simply enter a name of your liking and the OK button will be clickable now. What is happening is that the window isnt really asking you chose a .jks file but rather it wants you to give it the location and name that you want it to have.
Step 4 Click on Next and then select Release and Voila ! you are done.
m/ /g
just give space in / /
, and it will work. Or use \S
— it will replace all the special characters like tab, newlines, spaces, and so on.
You will want to remove()
the item from your adapter object and then just run the notifyDatasetChanged()
on the Adapter, any ListView
s will (should) recycle and update on it's own.
Here's a brief activity example with AlertDialog
s:
adapter = new MyListAdapter(this);
lv = (ListView) findViewById(android.R.id.list);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
AlertDialog.Builder adb=new AlertDialog.Builder(MyActivity.this);
adb.setTitle("Delete?");
adb.setMessage("Are you sure you want to delete " + position);
final int positionToRemove = position;
adb.setNegativeButton("Cancel", null);
adb.setPositiveButton("Ok", new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
MyDataObject.remove(positionToRemove);
adapter.notifyDataSetChanged();
}});
adb.show();
}
});
You can do these conversions also with the .NET Framework:
JSON to XML: by using System.Runtime.Serialization.Json
var xml = XDocument.Load(JsonReaderWriterFactory.CreateJsonReader(
Encoding.ASCII.GetBytes(jsonString), new XmlDictionaryReaderQuotas()));
XML to JSON: by using System.Web.Script.Serialization
var json = new JavaScriptSerializer().Serialize(GetXmlData(XElement.Parse(xmlString)));
private static Dictionary<string, object> GetXmlData(XElement xml)
{
var attr = xml.Attributes().ToDictionary(d => d.Name.LocalName, d => (object)d.Value);
if (xml.HasElements) attr.Add("_value", xml.Elements().Select(e => GetXmlData(e)));
else if (!xml.IsEmpty) attr.Add("_value", xml.Value);
return new Dictionary<string, object> { { xml.Name.LocalName, attr } };
}
In my case, it was due to an input in an array at an index equal to the length of the array.
string x[5];
for(int i=1; i<=5; i++){
cin>>x[i];
}
x[5] is being accessed which is not present.
Maximum value: 2147483647
setcookie("CookieName", "CookieValue", 2147483647);
To avoid integer overflow the timestamp should be set to:
2^31 - 1 = 2147483647 = 2038-01-19 04:14:07
Setting a higher value might cause problems with older browsers.
Also see the RFC about cookies:
Max-Age=value OPTIONAL. The value of the Max-Age attribute is delta-seconds, the lifetime of the cookie in seconds, a decimal non-negative integer. To handle cached cookies correctly, a client SHOULD calculate the age of the cookie according to the age calculation rules in the HTTP/1.1 specification [RFC2616]. When the age is greater than delta-seconds seconds, the client SHOULD discard the cookie. A value of zero means the cookie SHOULD be discarded immediately.
and RFC 2616, 14.6 Age:
If a cache receives a value larger than the largest positive integer it can represent, or if any of its age calculations overflows, it MUST transmit an Age header with a value of 2147483648 (2^31).
I would use the operator[].
map <char, int> m1;
m1['G'] ++; // If the element 'G' does not exist then it is created and
// initialized to zero. A reference to the internal value
// is returned. so that the ++ operator can be applied.
// If 'G' did not exist it now exist and is 1.
// If 'G' had a value of 'n' it now has a value of 'n+1'
So using this technique it becomes really easy to read all the character from a stream and count them:
map <char, int> m1;
std::ifstream file("Plop");
std::istreambuf_iterator<char> end;
for(std::istreambuf_iterator<char> loop(file); loop != end; ++loop)
{
++m1[*loop]; // prefer prefix increment out of habbit
}
If you are running IIS on your PC you can add the directory that you are trying to reach as a Virtual Directory. To do this you right-click on your Site in ISS and press "Add Virtual Directory". Name the virtual folder. Point the virtual folder to your folder location on your local PC. You also have to supply credentials that has privileges to access the specific folder eg. HOSTNAME\username and password. After that you can access the file in the virtual folder as any other file on your site.
http://sitename.com/virtual_folder_name/filename.fileextension
By the way, this also works with Chrome that otherwise does not accept the file-protocol file://
Hope this helps someone :)
Below method would convert array to object with particular given key.
/**
* Converts array to object
* @param {Array} array
* @param {string} key (optional)
*/
Array.prototype.ArrayToObject = function(key) {
const array = this;
const obj = {};
array.forEach((element, index) => {
if(!key) {
obj[index] = element;
} else if ((element && typeof element == 'object' && element[key])) {
obj[element[key]] = element;
}
});
return obj;
}
For Ex -
[{name: 'test'}, {name: 'test1'}].ArrayToObject('name');
would give
{test: {name: 'test'}, test1: {name: 'test1'}}
and incase key is not provided as param to the method
i.e. [{name: 'test'}, {name: 'test1'}].ArrayToObject();
would give
{0: {name: 'test'}, 1: {name: 'test1'}}
I guess I found a simpler solution
temp1 = pd.melt(df1, id_vars=["location"], var_name='Date', value_name='Value')
temp2 = pd.melt(df1, id_vars=["name"], var_name='Date', value_name='Value')
Concat whole temp1
with temp2
's column name
temp1['new_column'] = temp2['name']
You now have what you asked for.
Java has a class specifically for zip files and one even more specifically for Jar Files.
java.util.jar.JarOutputStream
java.util.jar.JarInputStream
using those you could, on a command from the console, using a scanner set to system.in
Scanner console = new Scanner(System.in);
String input = console.nextLine();
then get all the components and write them as a file.
JarEntry JE = null;
while((JE = getNextJarEntry()) != null)
{
//do stuff with JE
}
You can also use java.util.zip.ZipInputStream instead, as seeing a JAR file is in the same format as a ZIP file, ZipInputStream will be able to handle the Jar file, in fact JarInputStream actually extends ZipInputStream.
an alternative is also instead of getNextJarEntry, to use getNextEntry
This is the trick I use. Good for responsive designs. Works perfectly when user tries to mess with browser resizing.

A better JQuery answer would be:
$('#ParentContainer').scroll(function() {
$('#FixedDiv').animate({top:$(this).scrollTop()});
});
You can also add a number after scrollTop i.e .scrollTop() + 5 to give it buff.
A good suggestion would also to limit the duration to 100 and go from default swing to linear easing.
$('#ParentContainer').scroll(function() {
$('#FixedDiv').animate({top:$(this).scrollTop()},100,"linear");
})
This would be a simpler approach

If you are working with MVC C#, this is the way to deal with printers and serial ports for dropdowns.
using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;
using System.Drawing.Printing;

List<PortClass> ports = new List<PortClass>();
List<Printersclass> Printersfor = new List<Printersclass>();

/*PORTS*/
for (int i = 0; i < portnames.Count(); i++)
{
ports.Add(new PortClass() { Name = portnames[i].Trim(), Desc = portnames[i].Trim() });
}
/*PRINTER*/
for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
{
Printersfor.Add(new Printersclass() { Name = PrinterSettings.InstalledPrinters[i].Trim(), Desc = PrinterSettings.InstalledPrinters[i].Trim() });
}
}
}
public class PortClass
{
public string Name { get; set; }
public string Desc { get; set; }
public override string ToString()
{
return string.Format("{0} ({1})", Name, Desc);
}
}
public class Printersclass
{
public string Name { get; set; }
public string Desc { get; set; }
public override string ToString()
{
return string.Format("{0} ({1})", Name, Desc);

Prefer to use numpy.ndarray
for multi-dimensional arrays.
The reason I used a +
instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.
word[Aa]\s+word[Bb]\s+word[Cc]
will match:
wordA wordB wordC
worda wordb wordc

The words, in this expression, will have to be specific, and also in order (a, b, then c)

You should enable the management plugin.
rabbitmq-plugins enable rabbitmq_management
See here:
http://www.rabbitmq.com/plugins.html
And here for the specifics of management.
http://www.rabbitmq.com/management.html
Finally once set up you will need to follow the instructions below to install and use the rabbitmqadmin tool. Which can be used to fully interact with the system. http://www.rabbitmq.com/management-cli.html
For example:
rabbitmqadmin get queue=<QueueName> requeue=false
will give you the first message off the queue.
Why not execute in backticks ?
x=`echo "$y" | tr '[:upper:]' '[:lower:]'`
This assigns the result of the command in backticks to the variable x
. (i.e. it's not particular to tr
but is a common pattern/solution for shell scripting)
You can use $(..)
instead of the backticks. See here for more info.

You can try Guava's multimaps:
TreeMap<Integer, Collection<String>> sortedMap = new TreeMap<>(
Multimaps.invertFrom(Multimaps.forMap(originalMap),
ArrayListMultimap.<Integer, String>create()).asMap());
As a result you get a map from original values to collections of keys that correspond to them. This approach can be used even if there are multiple keys for the same value.
The existing answers all seem to run this script in a DOS console window.
This may be acceptable, but for example means that colour codes (changing text colour) don't work but instead get printed out as they are:

I found this solution some time ago, so I'm not sure whether mintty.exe
is a standard Cygwin utility or whether you have to run the setup
program to get it, but I run like this:
D:\apps\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico bash.exe .\myShellScript.sh
... this causes the script to run in a Cygwin BASH console instead of a Windows DOS console.
Knowing that ActivityManager manages Activity, so we can gain information from ActivityManager. We get the current foreground running Activity by
ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
ComponentName cn = am.getRunningTasks(1).get(0).topActivity;
UPDATE 2018/10/03
getRunningTasks() is DEPRECATED. see the solutions below.
This method was deprecated in API level 21. As of Build.VERSION_CODES.LOLLIPOP, this method is no longer available to third party applications: the introduction of document-centric recents means it can leak person information to the caller. For backwards compatibility, it will still return a small subset of its data: at least the caller's own tasks, and possibly some other tasks such as home that are known to not be sensitive.
You need to use v-bind:
or its alias :
. For example,
<a v-bind:href="'/job/'+ r.id">
or
<a :href="'/job/' + r.id">
For simple cases, I would also suggest looking at XmlOutput a fluent interface for building Xml.
XmlOutput is great for simple Xml creation with readable and maintainable code, while generating valid Xml. The orginal post has some great examples.
