Add below lines in your .profile path
PATH=$PATH:$HOME/bin:$Dir_where_script_exists
export PATH
Now your script should work without ./

I ran into a similar error
"from: can't read /var/mail/django.test.utils"
when trying to run a command
>>> from django.test.utils import setup_test_environment
>>> setup_test_environment()
in the tutorial at https://docs.djangoproject.com/en/1.8/intro/tutorial05/
after reading the answer by Tamás I realized I was not trying this command in the python shell but in the termnial (this can happen to those new to linux)
solution was to first enter in the python shell with the command python and when you get these >>> then run any python commands
An elegant way using pathlib.Path:
from pathlib import Path
p = Path('mysequence.fasta')
p.rename(p.with_suffix('.aln'))
Using file:///// just doesn't work if security settings are set to even a moderate level.
If you just want users to be able to download/view files* located on a network or share you can set up a Virtual Directory in IIS. On the Properties tab make sure the "A share located on another computer" is selected and the "Connect as..." is an account that can see the network location.
Link to the virtual directory from your webpage (e.g. http://yoursite/yourvirtualdir/) and this will open up a view of the directory in the web browser.
*You can allow write permissions on the virtual directory to allow users to add files but not tried it and assume network permissions would override this setting.
Latest and greatest way to do this:
Node supports file and buffer operations with the base64
encoding:
const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});
Or using the new promises API:
const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});
ulimit -s unlimited
lets the stack grow unlimited.
This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.
You can use reference type in generic arguments, not primitive type. So here you should use
Map<String, Integer> myMap = new HashMap<String, Integer>();
and store value as
myMap.put("abc", 5);
I had the same error, because of the JUnit version. I had three 3.8.1, and I have changed to 4.8.1.
So the solution is:
You have to go to the POM, and make sure that you dependency looks like this
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.1</version>
<scope>test</scope>
</dependency>
strtotime()
is returning bool(false)
, because it can't parse the string '+one year'
(it doesn't understand "one"). false
is then being implicitly cast to the integer
timestamp 0
. It's a good idea to verify strtotime()
's output isn't bool(false)
before you go shoving it in other functions.
Return Values
Returns a timestamp on success, FALSE otherwise. Previous to PHP 5.1.0, this function would return -1 on failure.
You can use jQuery's attr()
function, like $("#id").attr('src',"source")
.
This is the sample code for the email and javascript.
params = getParams();
subject = "ULM Query of: ";
subject += unescape(params["FormsEditField3"]);
content = "Email: ";
content += unescape(params["FormsMultiLine2"]);
content += " Query: ";
content += unescape(params["FormsMultiLine4"]);
var email = "[email protected]";
document.write('<a href="mailto:'+email+'?subject='+subject+'&body='+content+'">SUBMIT QUERY</a>');
this should be the most obvious and straight forward way

If you are getting this Error java.lang.OutOfMemoryError this is the most common problem occurs in Android. This error is thrown by the Java Virtual Machine (JVM) when an object cannot be allocated due to lack of memory space.
Try this android:hardwareAccelerated="false" , android:largeHeap="true"
in your
manifest.xml file under application like this:
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:hardwareAccelerated="false"
android:largeHeap="true" />
The column in the database is probably a DECIMAL
. You should process it as a BigInteger
, not an Integer
, otherwise you are losing digits. Or else change the column to int
.
Let's say you have a collection of Car
objects (database rows), and each Car
has a collection of Wheel
objects (also rows). In other words, Car
? Wheel
is a 1-to-many relationship.
Now, let's say you need to iterate through all the cars, and for each one, print out a list of the wheels. The naive O/R implementation would do the following:
SELECT * FROM Cars;
And then for each Car
:
SELECT * FROM Wheel WHERE CarId = ?
In other words, you have one select for the Cars, and then N additional selects, where N is the total number of cars.
Alternatively, one could get all wheels and perform the lookups in memory:
SELECT * FROM Wheel
This reduces the number of round-trips to the database from N+1 to 2. Most ORM tools give you several ways to prevent N+1 selects.

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
In the context of EF, marking a property as virtual allows EF to use lazy loading to load it. For lazy loading to work EF has to create a proxy object that overrides your virtual properties with an implementation that loads the referenced entity when it is first accessed. If you don't mark the property as virtual then lazy loading won't work with it.

I was facing the same problem when import projects into IntelliJ.
for in my case first, check SDK details and check you have configured JDK correctly or not.
Go to File-> Project Structure-> platform Settings-> SDKs
Check your JDK is correct or not.
Next, I Removed project from IntelliJ and delete all IntelliJ and IDE related files and folder from the project folder (.idea, .settings, .classpath, dependency-reduced-pom). Also, delete the target folder and re-import the project.
The above solution worked in my case.
How about using java 8 streams.
nodeMap.entrySet().stream().filter(x->x.getKey().equalsIgnoreCase(stringfromEven.toString()).collect(Collectors.toList())
This is to synchronize IOs from C and C++ world. If you synchronize, then you have a guaranty that the orders of all IOs is exactly what you expect. In general, the problem is the buffering of IOs that causes the problem, synchronizing let both worlds to share the same buffers. For example cout << "Hello"; printf("World"); cout << "Ciao";
; without synchronization you'll never know if you'll get HelloCiaoWorld
or HelloWorldCiao
or WorldHelloCiao
...
tie
lets you have the guaranty that IOs channels in C++ world are tied one to each other, which means for example that every output have been flushed before inputs occurs (think about cout << "What's your name ?"; cin >> name;
).
You can always mix C or C++ IOs, but if you want some reasonable behavior you must synchronize both worlds. Beware that in general it is not recommended to mix them, if you program in C use C stdio, and if you program in C++ use streams. But you may want to mix existing C libraries into C++ code, and in such a case it is needed to synchronize both.
Try the following regex:
var removedText = self.val().replace(/[^0-9]/, '');
This will match every character that is not (^
) in the interval 0-9.

Yes, you may use an anchor by specifying the id
attribute of an element and then linking to it with a hash.
For example (taken from the W3 specification):
You may read more about this in <A href="#section2">Section Two</A>.

$SQL="SELECT * FROM products WHERE catid IN "+$SQL_Part;
It's more generic and will fit for any array!!
setState()
is usually asynchronous, which means that at the time you console.log
the state, it's not updated yet. Try putting the log in the callback of the setState()
method. It is executed after the state change is complete:
this.setState({ dealersOverallTotal: total }, () => {
console.log(this.state.dealersOverallTotal, 'dealersOverallTotal1');
});
Using perl rename (a must have in the toolbox):
rename -n 's/0000/000/' F0000*
Remove -n
switch when the output looks good to rename for real.
There are other tools with the same name which may or may not be able to do this, so be careful.
The rename command that is part of the util-linux
package, won't.
If you run the following command (GNU
)
$ rename
and you see perlexpr
, then this seems to be the right tool.
If not, to make it the default (usually already the case) on Debian
and derivative like Ubuntu
:
$ sudo apt install rename
$ sudo update-alternatives --set rename /usr/bin/file-rename
For archlinux:
pacman -S perl-rename
For RedHat-family distros:
yum install prename
The 'prename' package is in the EPEL repository.
For Gentoo:
emerge dev-perl/rename
For *BSD:
pkg install gprename
or p5-File-Rename
For Mac users:
brew install rename
If you don't have this command with another distro, search your package manager to install it or do it manually:
cpan -i File::Rename

This tool was originally written by Larry Wall, the Perl's dad.
#include <EnumString.h>
from http://www.codeproject.com/Articles/42035/Enum-to-String-and-Vice-Versa-in-C and after
enum FORM {
F_NONE = 0,
F_BOX,
F_CUBE,
F_SPHERE,
};
insert
Begin_Enum_String( FORM )
{
Enum_String( F_NONE );
Enum_String( F_BOX );
Enum_String( F_CUBE );
Enum_String( F_SPHERE );
}
End_Enum_String;
Works fine if values in the enum are not duplicate.
Sample code for converting an enum value to string:
enum FORM f = ...
const std::string& str = EnumString< FORM >::From( f );
Sample code for just the opposite:
assert( EnumString< FORM >::To( f, str ) );
setTimeout
is a kind of Thread, it holds a operation for a given time and execute.
setTimeout(function,time_in_mills);
in here the first argument should be a function type; as an example if you want to print your name after 3 seconds, your code should be something like below.
setTimeout(function(){console.log('your name')},3000);
Key point to remember is, what ever you want to do by using the setTimeout
method, do it inside a function. If you want to call some other method by parsing some parameters, your code should look like below:
setTimeout(function(){yourOtherMethod(parameter);},3000);
Your mock is raising the exception just fine, but the error.resp.status
value is missing. Rather than use return_value
, just tell Mock
that status
is an attribute:
barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
Additional keyword arguments to Mock()
are set as attributes on the resulting object.
I put your foo
and bar
definitions in a my_tests
module, added in the HttpError
class so I could use it too, and your test then can be ran to success:
>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
... barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
... result = my_test.foo()
...
404 -
>>> result is None
True
You can even see the print '404 - %s' % error.message
line run, but I think you wanted to use error.content
there instead; that's the attribute HttpError()
sets from the second argument, at any rate.
I needed to do this for an AWS ELB. After getting beaten up by the dialog many times, finally this is what worked for me:
openssl rsa -in server.key -text > private.pem
openssl x509 -inform PEM -in server.crt > public.pem
Thanks NCZ
Edit: As @floatingrock says
With AWS, don't forget to prepend the filename with file://
. So it'll look like:
aws iam upload-server-certificate --server-certificate-name blah --certificate-body file://path/to/server.crt --private-key file://path/to/private.key --path /cloudfront/static/
http://docs.aws.amazon.com/cli/latest/reference/iam/upload-server-certificate.html
Sphinx is mainly a tool for formatting docs written independently from the source code, as I understand it.
For generating API docs from Python docstrings, the leading tools are pdoc and pydoctor. Here's pydoctor's generated API docs for Twisted and Bazaar.
Of course, if you just want to have a look at the docstrings while you're working on stuff, there's the "pydoc" command line tool and as well as the help()
function available in the interactive interpreter.
Your solution is nearly correct. You could add DISTINCT:
SELECT
people.pe_name,
COUNT(distinct orders.ord_id) AS num_orders,
COUNT(items.item_id) AS num_items
FROM
people
INNER JOIN orders ON (orders.pe_id = people.pe_id)
INNER JOIN items ON items.pe_id = people.pe_id
GROUP BY
people.pe_id;
They have a very good answer here: https://stackoverflow.com/a/32455275/165865
Just run below images:
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz images -t
Rather than removing n characters from the start, perhaps you could just extract the digits directly. Like so...
$ echo "pid: 1234" | grep -Po "\d+"
This may be a more robust solution, and seems more intuitive.
Getting a stack trace of an unprepared python program, running in a stock python without debugging symbols can be done with pyrasite. Worked like a charm for me in on Ubuntu Trusty:
$ sudo pip install pyrasite
$ echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
$ sudo pyrasite 16262 dump_stacks.py # dumps stacks to stdout/stderr of the python program
(Hat tip to @Albert, whose answer contained a pointer to this, among other tools.)
The line
when(someObject.doSomething(argumentCaptor.capture())).thenReturn(true);
would do the same as
when(someObject.doSomething(Matchers.any())).thenReturn(true);
So, using argumentCaptor.capture() when stubbing has no added value. Using Matchers.any() shows better what really happens and therefor is better for readability. With argumentCaptor.capture(), you can't read what arguments are really matched. And instead of using any(), you can use more specific matchers when you have more information (class of the expected argument), to improve your test.
And another problem: If using argumentCaptor.capture() when stubbing it becomes unclear how many values you should expect to be captured after verification. We want to capture a value during verification, not during stubbing because at that point there is no value to capture yet. So what does the argument captors capture method capture during stubbing? It capture anything because there is nothing to be captured yet. I consider it to be undefined behavior and I don't want to use undefined behavior.
I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)
The screen you show is DateTimeSettings
. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time";
and also to Settings.System.AUTO_TIME
This settings is observed by an observed called mAutoTimeObserver
in the 2 network ServiceStateTracker
s:
GsmServiceStateTracker
and CdmaServiceStateTracker
.
Both implementations call a method called revertToNitz()
when the settings becomes true.
Apparently NITZ is the equivalent of NTP in the carrier world.
Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz()
.
Unfortunately, I haven't found a mechanism to get the network time.
If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTracker
s implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime
.
I did some development with Mifare Classic (ISO 14443A) cards about 7-8 years ago. You can read and write to all sectors of the card, IIRC the only data you can't change is the serial number. Back then we used a proprietary library from Philips Semiconductors. The command interface to the card was quite alike the ISO 7816-4 (used with standard Smart Cards).
I'd recomment that you look at the OpenPCD platform if you are into development.
This is also of interest regarding the cryptographic functions in some RFID cards.
CONVERT(VARCHAR, GETDATE(), 23)
The following, with an additional dot before the index, works just as expected. Here, the square brackets are optional when the index is followed by another property:
{{people.[1].name}}
{{people.1.name}}
However, the square brackets are required in:
{{#with people.[1]}}
{{name}}
{{/with}}
In the latter, using the index number without the square brackets would get one:
Error: Parse error on line ...:
... {{#with people.1}}
-----------------------^
Expecting 'ID', got 'INTEGER'
As an aside: the brackets are (also) used for segment-literal syntax, to refer to actual identifiers (not index numbers) that would otherwise be invalid. More details in What is a valid identifier?
(Tested with Handlebars in YUI.)
You can now use the get
helper for this:
(get people index)
although if you get an error about index needing to be a string, do:
(get people (concat index ""))
in pure js just use offsetLeft
and offsetTop
properties.
Example fiddle: http://jsfiddle.net/WKZ8P/
var elm = document.querySelector('span');_x000D_
console.log(elm.offsetLeft, elm.offsetTop);
_x000D_
p { position:relative; left:10px; top:85px; border:1px solid blue; }_x000D_
span{ position:relative; left:30px; top:35px; border:1px solid red; }
_x000D_
<p>_x000D_
<span>paragraph</span>_x000D_
</p>

Here is the directive I use. It automatically cleans itself up when the form is unloaded. If you want to prevent the prompt from firing (e.g. because you successfully saved the form), call $scope.FORMNAME.$setPristine(), where FORMNAME is the name of the form you want to prevent from prompting.
.directive('dirtyTracking', [function () {
return {
restrict: 'A',
link: function ($scope, $element, $attrs) {
function isDirty() {
var formObj = $scope[$element.attr('name')];
return formObj && formObj.$pristine === false;
}
function areYouSurePrompt() {
if (isDirty()) {
return 'You have unsaved changes. Are you sure you want to leave this page?';
}
}
window.addEventListener('beforeunload', areYouSurePrompt);
$element.bind("$destroy", function () {
window.removeEventListener('beforeunload', areYouSurePrompt);
});
$scope.$on('$locationChangeStart', function (event) {
var prompt = areYouSurePrompt();
if (!event.defaultPrevented && prompt && !confirm(prompt)) {
event.preventDefault();
}
});
}
};
}]);
I have encountered similar problem.
The root cause is that (use your scenario for my case), in the #temp table, there is no record for
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA)
So, when MSSQL does pivot for no record, MSSQL always shows NULL for MAX, SUM, ... (aggregate functions)
None of above solutions (IsNull([AZ], 0)) works for me. But I do get ideas from these solutions. Thanks.
Sorry, it really depends on the #TEMP table. I can only provide some suggestions.
1. Make sure #TEMP table have records for below condition, even Data is null.
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA)
You may need to use cartesian product: select A.*, B.* from A, B
2. In the select query for #temp, if you need to join any table with WHERE, then would better put where inside another sub select query. (Goal is 1.)
3. Use isnull(DATA, 0) in #TEMP table.
4. Before pivot, make sure you have achieved Goal 1.
I can't give an answer to the orginal question, since there is no enough info for #temp table. I have pasted my code as example here, hope this will help others.

Just drag and drop the DLL file into folder C:\Windows\assembly
using Windows Explorer.
Caveat:
In earlier versions of the .NET Framework, the Shfusion.dll Windows shell extension let you install assemblies by dragging them to File Explorer. Beginning with .NET Framework 4, Shfusion.dll is obsolete.
Source: How to: Install an assembly into the global assembly cache
Assuming you have a folder with A LOT of files reading them all and then deleting in two steps is not that performing. I believe the most performing way to delete files is to just use a system command.
For example on linux I use :
exec('rm -f '. $absolutePathToFolder .'*');
Or this if you want recursive deletion without the need to write a recursive function
exec('rm -f -r '. $absolutePathToFolder .'*');
the same exact commands exists for any OS supported by PHP. Keep in mind this is a PERFORMING way of deleting files. $absolutePathToFolder MUST be checked and secured before running this code and permissions must be granted.
The best way to set any feature regarding the colors of any widget is to use QPalette.
And the easiest way to find what you are looking for is to open Qt Designer and set the palette of a QLabel and check the generated code.
You should declare the thread main as:
void* print_message(void*) // takes one parameter, unnamed if you aren't using it
You can use the library: https://github.com/vivchar/RendererRecyclerViewAdapter
mRecyclerViewAdapter = new RendererRecyclerViewAdapter(); /* included from library */
mRecyclerViewAdapter.registerRenderer(new SomeViewRenderer(SomeModel.TYPE, this));
mRecyclerViewAdapter.registerRenderer(...); /* you can use several types of cells */
For each item, you should to implement a ViewRenderer, ViewHolder, SomeModel:
ViewHolder - it is a simple view holder of recycler view.
SomeModel - it is your model with ItemModel
interface
public class SomeViewRenderer extends ViewRenderer<SomeModel, SomeViewHolder> {
public SomeViewRenderer(final int type, final Context context) {
super(type, context);
}
@Override
public void bindView(@NonNull final SomeModel model, @NonNull final SomeViewHolder holder) {
holder.mTitle.setText(model.getTitle());
}
@NonNull
@Override
public SomeViewHolder createViewHolder(@Nullable final ViewGroup parent) {
return new SomeViewHolder(LayoutInflater.from(getContext()).inflate(R.layout.some_item, parent, false));
}
}
For more details you can look documentations.
I have try to use:
<link rel="preload stylesheet" href="mystyles.css" as="style">
It works fines, but It also raises cumulative layout shift because when we use rel="preload", it just download css , not apply immediate.
Example when the DOM load a list contains ul, li tags, there is an bullets before li tags by default, then CSS applied that I remove these bullets to custom styles for listing. So that, the cumulative layout shift is happening here.
Is there any solution for that?
You should add this line
self.navigationController?.navigationBar.topItem?.backBarButtonItem?.tintColor = .black
For live video conferencing you can't ignore the need of a streaming server.
Yes, flash will let you display video from a webcam within the local flash control, but that won't let you then send that video over the network - for that you need a streaming server to send it to.
If you're going to build something like this it's prudent to think about how you're going to host the video from a very early stage as it will influence how you build the application. Flash/Flex/Silverlight/Windows Media....etc....
jbernadas already mentioned the Aho-Corasick-Algorithm in order to reduce complexity.
Here is one way to use it in Python:
Download aho_corasick.py from here
Put it in the same directory as your main Python file and name it aho_corasick.py
Try the alrorithm with the following code:
from aho_corasick import aho_corasick #(string, keywords)
print(aho_corasick(string, ["keyword1", "keyword2"]))
Note that the search is case-sensitive
Visual Studio has got now integrated support for range checking and type checking :-
Try this :- For RANGE CHECKING Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-
View>Toolbox>Validation
Now Drag on RangeValidator to your design page where you want to show the error message(ofcourse if user is inputting out of range value) now click on your RangeValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write :-
Number must be in range.
Now select on Control to validate and select your TextboxID (or write it anyways) from the drop down.Locate Type in the property bar itself and select down Integer.
Just above it you will find maximum and minimum value .Type in your desired number .
For Type checking (without any Range)
Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-
View>Toolbox>Validation
Now Drag on CompareValidator to your design page where you want to show the error message(ofcourse if user is inputting some text in it). now click on your CompareValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write:-
Value must be a number .
Now locate ControltoValidate option and write your controlID name in it(alternatively you can also select from drop down).Locate the Operator option and write DataTypeCheck(alternatively you can also select from drop down)in it .Again locate the Type option and write Integer in it .
That's sit.
Alternatively you can write the following code in your aspx page :- <%--to validate without any range--%>
One way to achieve this is using a position:fixed
container for the background image and place it outside of the .jumbotron
. Make the bg

and center the background image:
background: url('/assets/example/...jpg') no-repeat center center;
CSS
.bg {
background: url('/assets/example/bg_blueplane.jpg') no-repeat center center;
position: fixed;
width: 100%;
height: 350px; /*same height as jumbotron */
top:0;
left:0;
z-index: -1;
}
.jumbotron {
margin-bottom: 0px;
height: 350px;
color: white;
text-shadow: black 0.3em 0.3em 0.3em;
background:transparent;
}
Then use jQuery to decrease the height of the .jumbtron
as the window scrolls. Since the background image is centered in the DIV it will adjust accordingly -- creating a parallax affect.
JavaScript
var jumboHeight = $('.jumbotron').outerHeight();
function parallax(){
var scrolled = $(window).scrollTop();
$('.bg').css('height', (jumboHeight-scrolled) + 'px');
}
$(window).scroll(function(e){
parallax();
});
Demo
I did : git clone --bare "/GITREPOSITORIES/RepoA" "ssh://luc@EERSTENASDS119J/volume1/RepoA" Result : fatal: destination path 'ssh://luc@EERSTENASDS119J/volume1/RepoA' already exists and is not an empty directory.
The system created a directory ssh://luc@EERSTENASDS119J/volume1/RepoA in my current path.
So git clone did not interpret the URL specification. Used the workaround of Alec.
Of course, if you want something as close to TortoiseSVN as possible, you could just use TortoiseGit.
.c : 'C' source code
.h : Header file
Usually, the .c

I was looking for the same thing today and finally got a way to do it. I was hinted that it was possible due to the use of sconfig, which ask you if you want to change the computer name after joining it to a domain. Here is my raw code line. It might be enhanced but to tired to think about it for now.
$strCompName = Read-host 'Name '
$strAdmin = read-host "Authorized user for this operation "
$strDomain = read-host "Name of the domain to be joined "
add-computer -DomainName $strDomain -Credential $strAdmin
Rename-computer -newname $strCompName -DomainCredential $strAdmin
A slightly more complete example of scope:
from __future__ import print_function # for python 2 support

print("1. Global x:", x)
class Test(object):

print("2. Enclosed y:", y)
x = x + 1
print("3. Enclosed x:", x)
def method(self):
print("4. Enclosed self.x", self.x)
print("5. Global x", x)
try:
print(y)
except NameError as e:
print("6.", e)
def method_local_ref(self):
try:

except UnboundLocalError as e:
print("7.", e)
x = 200 # causing 7 because has same name
print("8. Local x", x)
inst = Test()
inst.method()
inst.method_local_ref()
output:
1. Global x: 100
2. Enclosed y: 100
3. Enclosed x: 101
4. Enclosed self.x 101
5. Global x 100
6. global name 'y' is not defined

This is a standalone example showing how to save the output of a user-written function in Python 3:
from io import StringIO
import sys
def print_audio_tagging_result(value):
print(f"value = {value}")
tag_list = []
for i in range(0,1):
save_stdout = sys.stdout
result = StringIO()
sys.stdout = result
print_audio_tagging_result(i)
sys.stdout = save_stdout
tag_list.append(result.getvalue())
print(tag_list)
Normally Python throws NameError
if the variable is not defined:
>>> d[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined
However, you've managed to stumble upon a name that already exists in Python.
Because dict
is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.
The type of dict
is a type
. All types are objects in Python. Thus you are actually trying to index into the type
object. This is why the error message says that the "'type' object is not subscriptable."
>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable
Note that you can blindly assign to the dict
name, but you really don't want to do that. It's just going to cause you problems later.
>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'
The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:
d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))
int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp =
new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);
imageView.setImageResource(id);
someLinearLayout.addView(imageView);
There is a package matrixStats

If you need to duplicate more than a few redirects, you might consider using a map:
# map is outside of server block
map $uri $redirect_uri {

~^/issue2/?$ http://example.com/shop/issues/custom_isse_name2;
~^/issue3/?$ http://example.com/shop/issues/custom_isse_name3;
# ... or put these in an included file
}
location / {
try_files $uri $uri/ @redirect-map;
}
location @redirect-map {
if ($redirect_uri) { # redirect if the variable is defined
return 301 $redirect_uri;
}
}
You can use c++ boost::property_tree::ptree for parsing json data. here is the example for your json data. this would be more easy if you shift name inside each child nodes
#include <iostream>

#include <tuple>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
int main () {
namespace pt = boost::property_tree;
pt::ptree loadPtreeRoot;
pt::read_json("example.json", loadPtreeRoot);
std::vector<std::tuple<std::string, std::string, std::string>> people;
pt::ptree temp ;
pt::ptree tage ;
pt::ptree tprofession ;
std::string age ;
std::string profession ;
//Get first child
temp = loadPtreeRoot.get_child("Anna");
tage = temp.get_child("age");
tprofession = temp.get_child("profession");
age = tage.get_value<std::string>();
profession = tprofession.get_value<std::string>();
std::cout << "age: " << age << "\n" << "profession :" << profession << "\n" ;
//push tuple to vector
people.push_back(std::make_tuple("Anna", age, profession));
//Get Second child
temp = loadPtreeRoot.get_child("Ben");
tage = temp.get_child("age");
tprofession = temp.get_child("profession");
age = tage.get_value<std::string>();
profession = tprofession.get_value<std::string>();
std::cout << "age: " << age << "\n" << "profession :" << profession << "\n" ;
//push tuple to vector
people.push_back(std::make_tuple("Ben", age, profession));
for (const auto& tmppeople: people) {
std::cout << "Child[" << std::get<0>(tmppeople) << "] = " << " age : "
<< std::get<1>(tmppeople) << "\n profession : " << std::get<2>(tmppeople) << "\n";
}
}

I had the same doubt about stateful v/s stateless class design and did some research. Just completed and my findings has been posted in my blog
It is an error on all Samsung devices, the solution is: put this line in your activity declaration in Manifest.
android:configChanges="orientation|screenSize"
also when you start the activity you should do this:
Intent intent = new Intent(CurrentActivity.this, NextActivity.class);
intent.setType(Settings.ACTION_SYNC_SETTINGS);
CurrentActivity.this.startActivity(intent);
finish();
I used this to make an activity as fullscreen mode, but this question does not need the fullscreen code, but in all cases might someone need it you can refer to this question for the rest of the code:
Actually, the following works fine for me and creates new windows:
test.cmd:
@echo off
start test2.cmd
start test3.cmd
echo Foo
pause
test2.cmd
@echo off
echo Test 2
pause
exit
test3.cmd
@echo off
echo Test 3
pause
exit
Combine that with parameters to start
, such as /min
, as Moshe pointed out if you don't want the new windows to spawn in front of you.
Use position: fixed
, and anchor it to the top
and right
sides of the page:
#fixed-div {
position: fixed;
top: 1em;
right: 1em;
}
IE6 does not support position: fixed
, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div>
to contain some of the styles for it to work, as seen in the stylesheet.
BigDecimal decPrec = (BigDecimal)yo.get("Avg");
decPrec = decPrec.setScale(5, RoundingMode.CEILING);
String value= String.valueOf(decPrec);
This way you can set specific precision of a BigDecimal
.
The value of decPrec was 1.5726903423607562595809913132345426
which is rounded off to 1.57267
.

Instead of IN
we can use ANY
with arrays casted to enum array, for example:
create type example_enum as enum (
'ENUM1', 'ENUM2'
);
create table example_table (
id integer,
enum_field example_enum
);
select
*
from
example_table t
where
t.enum_field = any(array['ENUM1', 'ENUM2']::example_enum[]);
Or we can still use 'IN' clause, but first, we should 'unnest' it:
select
*
from
example_table t
where
t.enum_field in (select unnest(array['ENUM1', 'ENUM2']::example_enum[]));

You get the index number of the row in the datagridview using northwind database employees tables as an example:
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication5
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'nORTHWNDDataSet.Employees' table. You can move, or remove it, as needed.
this.employeesTableAdapter.Fill(this.nORTHWNDDataSet.Employees);
}
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
var dataIndexNo = dataGridView1.Rows[e.RowIndex].Index.ToString();
string cellValue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();
MessageBox.Show("The row index = " + dataIndexNo.ToString() + " and the row data in second column is: "
+ cellValue.ToString());
}
}
}
the result will show you index number of record and the contents of the second table column in datagridview:

It's worth reading Oracle Java Tutorial - Getting and Setting Field Values
Field#set(Object object, Object value) sets the field represented by this Field
object on the specified object argument to the specified new value.
It should be like this
f.set(objectOfTheClass, new ConcurrentHashMap<>());
You can't set any value in null
Object If tried then it will result in NullPointerException
Note: Setting a field's value via reflection has a certain amount of performance overhead because various operations must occur such as validating access permissions. From the runtime's point of view, the effects are the same, and the operation is as atomic as if the value was changed in the class code directly.
In Mongoose, we can update array value using $set
inside dot(.
) notation to specific value in following way
db.collection.update({"_id": args._id, "viewData._id": widgetId}, {$set: {"viewData.$.widgetData": widgetDoc.widgetData}})
But from what I understand xs:choice still only allows single element selection. Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple times. Is this accurate?
No. The choice happens individually for every "repetition" of xs:choice
that occurs due to maxOccurs="unbounded"
. Therefore, the code that you have posted is correct, and will actually do what you want as written.
Using simply tr :
$ tr ':' $'\n' <<< string1:string2:string3:string4:string5

If you really need sed :
$ sed 's/:/\n/g' <<< string1:string2:string3:string4:string5
string1
string2
string3
string4
string5
If you have sed:
sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]
Where FILENAME
is the name of the text file with the good & bad lines
First make sure you have SessionMiddleware

The current user
is in request
object, you can get it by:
def sample_view(request):
current_user = request.user
print current_user.id
request.user
will give you a User
object representing the currently logged-in user. If a user isn't currently logged in, request.user
will be set to an instance of AnonymousUser
. You can tell them apart with the field is_authenticated
, like so:
if request.user.is_authenticated:
# Do something for authenticated users.
else:
# Do something for anonymous users.
The latest version of XMLUnit can help the job of asserting two XML are equal. Also XMLUnit.setIgnoreWhitespace()
and XMLUnit.setIgnoreAttributeOrder()
may be necessary to the case in question.
See working code of a simple example of XML Unit use below.
import org.custommonkey.xmlunit.DetailedDiff;
import org.custommonkey.xmlunit.XMLUnit;
import org.junit.Assert;
public class TestXml {
public static void main(String[] args) throws Exception {
String result = "<abc attr=\"value1\" title=\"something\"> </abc>";
// will be ok
assertXMLEquals("<abc attr=\"value1\" title=\"something\"></abc>", result);
}
public static void assertXMLEquals(String expectedXML, String actualXML) throws Exception {
XMLUnit.setIgnoreWhitespace(true);
XMLUnit.setIgnoreAttributeOrder(true);
DetailedDiff diff = new DetailedDiff(XMLUnit.compareXML(expectedXML, actualXML));
List<?> allDifferences = diff.getAllDifferences();
Assert.assertEquals("Differences found: "+ diff.toString(), 0, allDifferences.size());
}
}
If using Maven, add this to your pom.xml
:
<dependency>

Here's some mapping that could help:
:nnoremap <Leader>q" ciw""<Esc>P
:nnoremap <Leader>q' ciw''<Esc>P
:nnoremap <Leader>qd daW"=substitute(@@,"'\\\|\"","","g")<CR>P
If you haven't changed the mapleader variable, then activate the mapping with \q"
\q'
or \qd
. They add double quote around the word under the cursor, single quote around the word under the cursor, delete any quotes around the word under the cursor respectively.
how will I know that some tables are locked?
You can use SHOW OPEN TABLES command to view locked tables.
how do I unlock tables manually?
If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.
Additionally, you will see that float
values are rounded.
// e.g: given values 41.0473112,29.0077011 float(11,7) | decimal(11,7) --------------------------- 41.0473099 | 41.0473112 29.0077019 | 29.0077011
ENV['RAILS_ENV']

new member so unfortunately im unable to comment or vote up, however Stephen Daye's post above was the perfect solution to the exact same problem that i've been looking for help with.
a small alteration to the following line:
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;
to:
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < (GPS_UPDATE_INTERVAL * 2);
basically as im building a slow paced game and my update interval is already set to 5 seconds, once the gps signal is out for 10+ seconds, thats the right time to trigger off something.
cheers mate, spent about 10 hours trying to solve this solution before i found your post :)
From within a Dockerfile something like the following should do the trick:
RUN apt-get update && \
apt-get install -y net-tools
From memory it's best practice to combine the update and the package installation lines to prevent docker caching the update step which can result in out-dated packages being installed.
Installing it via the CLI or a shell script:
apt-get update && apt-get install net-tools
This is what I did in my application
NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
Hopefully this simple answer will help somebody...
The best would be to use:
df.isna().any().any()
Here is why. So isna()
is used to define isnull()
, but both of these are identical of course.
This is even faster than the accepted answer and covers all 2D panda arrays.
Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.
Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.
The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

The INSERT INTO Statement
The INSERT INTO statement is used to insert a new row in a table.
SQL INSERT INTO Syntax
It is possible to write the INSERT INTO statement in two forms.
The first form doesn't specify the column names where the data will be inserted, only their values:
INSERT INTO table_name
VALUES (value1, value2, value3,...)
The second form specifies both the column names and the values to be inserted:
INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)
You need to include xmlbeans-xxx.jar and if you have downloaded the POI binary zip, you will get the xmlbeans-xxx.jar in ooxml-lib folder (eg: \poi-3.11\ooxml-lib)

while ((content = in.readLine()) != null)
System.out.println(content);
You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }

directory. Robocopy normally
overwrites those. /XO
excludes
existing files older
than the copy in the source
directory. Robocopy normally
overwrites those.With the Changed, Older, and Newer classes excluded, Robocopy does exactly what the original poster wants - without needing to load a scripting environment.

Up and coming to the HTML5 scene is the download attribute. It's supported in Firefox and Chrome, and soon to come to IE11. Depending on your needs, you could use it instead of an AJAX request (or using window.location
) so long as the file you want to download is on the same origin as your site.
You could always make the AJAX request/window.location
a fallback by using some JavaScript to test if download
is supported and if not, switching it to call window.location
.
Original answer
You can't have an AJAX request open the download prompt since you physically have to navigate to the file to prompt for download. Instead, you could use a success function to navigate to download.php. This will open the download prompt but won't change the current page.
$.ajax({
url: 'download.php',
type: 'POST',
success: function() {
window.location = 'download.php';
}
});
Even though this answers the question, it's better to just use window.location
and avoid the AJAX request entirely.
If you are using intellij, then try restarting intellij cache
See if it works, it worked for me.
@marc_s's answer is very great and I've been using it for few years. However, I noticed that the script misses data in some columnstore indexes and doesn't show complete picture. E.g. when you do SUM(TotalSpace)
against the script and compare it with total space database property in Management Studio the numbers don't match in my case (Management Studio shows larger numbers). I modified the script to overcome this issue and extended it a little bit:
select
tables.[name] as table_name,
schemas.[name] as schema_name,
isnull(db_name(dm_db_index_usage_stats.database_id), 'Unknown') as database_name,
sum(allocation_units.total_pages) * 8 as total_space_kb,
cast(round(((sum(allocation_units.total_pages) * 8) / 1024.00), 2) as numeric(36, 2)) as total_space_mb,
sum(allocation_units.used_pages) * 8 as used_space_kb,
cast(round(((sum(allocation_units.used_pages) * 8) / 1024.00), 2) as numeric(36, 2)) as used_space_mb,
(sum(allocation_units.total_pages) - sum(allocation_units.used_pages)) * 8 as unused_space_kb,
cast(round(((sum(allocation_units.total_pages) - sum(allocation_units.used_pages)) * 8) / 1024.00, 2) as numeric(36, 2)) as unused_space_mb,
count(distinct indexes.index_id) as indexes_count,
max(dm_db_partition_stats.row_count) as row_count,
iif(max(isnull(user_seeks, 0)) = 0 and max(isnull(user_scans, 0)) = 0 and max(isnull(user_lookups, 0)) = 0, 1, 0) as no_reads,
iif(max(isnull(user_updates, 0)) = 0, 1, 0) as no_writes,
max(isnull(user_seeks, 0)) as user_seeks,

Here is another method to add days on date using dateutil's relativedelta.
from datetime import datetime
from dateutil.relativedelta import relativedelta
print 'Today: ',datetime.now().strftime('%d/%m/%Y %H:%M:%S')
date_after_month = datetime.now()+ relativedelta(days=5)
print 'After 5 Days:', date_after_month.strftime('%d/%m/%Y %H:%M:%S')
Output:
Today: 25/06/2015 15:56:09
After 5 Days: 30/06/2015 15:56:09
You could include the same project in more than one solution, but you're guaranteed to run into problems sometime down the road (relative paths can become invalid when you move directories around for example)
After years of struggling with this, I finally came up with a workable solution, but it requires you to use Subversion for source control (which is not a bad thing)
At the directory level of your solution, add a svn:externals property pointing to the projects you want to include in your solution. Subversion will pull the project from the repository and store it in a subfolder of your solution file. Your solution file can simply use relative paths to refer to your project.
If I find some more time, I'll explain this in detail.
Simplest way to do this is:
import boto3
s3 = boto3.resource("s3")
bucket_source = {
'Bucket': "my-bcuket",
'Key': "file_path_in_bucket"
}
s3.meta.client.delete(bucket_source)
If you support IE, for versions of Internet Explorer 8 and above, this:
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />
Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.
If you separate with semi-colon, it sets compatibility levels for different versions. For example:
<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />
Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:
<meta http-equiv="X-UA-Compatible" content="IE=8" />
This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
For this:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
It forces the browser the render at whatever the most recent version's standards are.
For more information, there is plenty to read about on MSDN,
A more object oriented way would be to provide a range to the #[] method. For instance:
Say you want the first 3 items from an array.
numbers = [1,2,3,4,5,6]
numbers[0..2] # => [1,2,3]
Say you want the first x items from an array.
numbers[0..x-1]
The great thing about this method is if you ask for more items than the array has, it simply returns the entire array.
numbers[0..100] # => [1,2,3,4,5,6]
That's one of most useless desires of beginner Android developers, and unfortunately it seems to be very popular. How do you define "close" an Android application? Hide it's user interface? Interrupt background work? Stop handling broadcasts?
Android applications are a set of modules, bundled in an .apk and exposed to the system trough AndroidManifest.xml. Activities can be arranged and re-arranged trough different task stacks, and finish()-ing or any other navigating away from a single Activity may mean totally different things in different situations. Single application can run inside multiple processes, so killing one process doesn't necessary mean there will be no application code left running. And finally, BroadcastReceivers can be called by the system any time, recreating the needed processes if they are not running.
The main thing is that you don't need to stop/kill/close/whatever your app trough a single line of code. Doing so is an indication you missed some important point in Android development. If for some bizarre reason you have to do it, you need to finish() all Activities, stop all Services and disable all BroadcastReceivers declared in AndroidManifest.xml. That's not a single line of code, and maybe launching the Activity that uninstalls your own application will do the job better.
I always use an easy method. Just add below lines to \public\index.php
file. You don't have to use a middleware I think.
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
If anyone comes to this thread and has this issue when you remote to a VMware VM with windows 10 1903, disabling 3d in the graphics card worked for me.

You get an extension ID when you upload your extension to Google Web Store. Ie. Adblock has URL https://chrome.google.com/webstore/detail/cfhdojbkjhnklbpkdaibdccddilifddb
and the last part of this URL is its extension ID cfhdojbkjhnklbpkdaibdccddilifddb
.
If you wish to read installed extension IDs from your extension, check out the managment module. chrome.management.getAll
allows to fetch information about all installed extensions.
I'd like to give a small addition to the existing answers. You get the same "Unclosed Character Literal error", if you give value to a char with incorrect unicode form. Like when you write:
char HI = '\3072';
You have to use the correct form which is:
char HI = '\u3072';
I think the answer you are after is implied (if not stated) by Vinko's answer, though it is not spelled out simply. To distinguish whether VAR is set but empty or not set, you can use:
if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi
if [ -z "$VAR" ] && [ "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi
You probably can combine the two tests on the second line into one with:
if [ -z "$VAR" -a "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi
However, if you read the documentation for Autoconf, you'll find that they do not recommend combining terms with '-a
' and do recommend using separate simple tests combined with &&
. I've not encountered a system where there is a problem; that doesn't mean they didn't used to exist (but they are probably extremely rare these days, even if they weren't as rare in the distant past).
You can find the details of these, and other related shell parameter expansions, the test
or [
command and conditional expressions in the Bash manual.
I was recently asked by email about this answer with the question:
You use two tests, and I understand the second one well, but not the first one. More precisely I don't understand the need for variable expansion
if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi
Wouldn't this accomplish the same?
if [ -z "${VAR}" ]; then echo VAR is not set at all; fi
Fair question - the answer is 'No, your simpler alternative does not do the same thing'.
Suppose I write this before your test:
VAR=
Your test will say "VAR is not set at all", but mine will say (by implication because it echoes nothing) "VAR is set but its value might be empty". Try this script:
(
unset VAR
if [ -z "${VAR+xxx}" ]; then echo JL:1 VAR is not set at all; fi
if [ -z "${VAR}" ]; then echo MP:1 VAR is not set at all; fi
VAR=
if [ -z "${VAR+xxx}" ]; then echo JL:2 VAR is not set at all; fi
if [ -z "${VAR}" ]; then echo MP:2 VAR is not set at all; fi
)
The output is:
JL:1 VAR is not set at all
MP:1 VAR is not set at all
MP:2 VAR is not set at all
In the second pair of tests, the variable is set, but it is set to the empty value. This is the distinction that the ${VAR=value}
and ${VAR:=value}
notations make. Ditto for ${VAR-value}
and ${VAR:-value}
, and ${VAR+value}
and ${VAR:+value}
, and so on.
As Gili points out in his answer, if you run bash
with the set -o nounset
option, then the basic answer above fails with unbound variable
. It is easily remedied:
if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi
if [ -z "${VAR-}" ] && [ "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi
Or you could cancel the set -o nounset
option with set +u
(set -u
being equivalent to set -o nounset
).
Use this:
while IFS= read -r file ; do rm -- "$file" ; done < delete.list
If you need glob expansion you can omit quoting $file
:
IFS=""
while read -r file ; do rm -- $file ; done < delete.list
But be warned that file names can contain "problematic" content and I would use the unquoted version. Imagine this pattern in the file
*
*/*
*/*/*
This would delete quite a lot from the current directory! I would encourage you to prepare the delete list in a way that glob patterns aren't required anymore, and then use quoting like in my first example.
There is this extensions that adds an event listener to attribute changes.
Usage:
<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<script type="text/javascript"
src="https://cdn.rawgit.com/meetselva/attrchange/master/js/attrchange.js"></script>
Bind attrchange handler function to selected elements
$(selector).attrchange({
trackValues: true, /* Default to false, if set to true the event object is
updated with old and new value.*/
callback: function (event) {
//event - event object
//event.attributeName - Name of the attribute modified
//event.oldValue - Previous value of the modified attribute
//event.newValue - New value of the modified attribute
//Triggered when the selected elements attribute is added/updated/removed
}
});
CORS is Cross Origin Resource Sharing, you get this error if you are trying to access from one domain to another domain.
Try using JSONP. In your case, JSONP should work fine because it only uses the GET method.
Try something like this:
var url = "https://api.getevents.co/event?&lat=41.904196&lng=12.465974";
$http({
method: 'JSONP',
url: url
}).
success(function(status) {
//your code when success
}).
error(function(status) {
//your code when fails
});
You can do it with pseudo-elements: (demo on dabblet.com)
your markup:
<div class="parent">
<div class="child"> Hello I am child </div>
</div>
css:
.parent{
position: relative;
}
.parent:before {
z-index: -1;
content: '';
position: absolute;
opacity: 0.2;
width: 400px;
height: 200px;
background: url('http://img42.imageshack.us/img42/1893/96c75664f7e94f9198ad113.png') no-repeat 0 0;
}
.child{
Color:black;
}
I definitely prefer Version 1. Version 2 may require less lines of code, but it will be extremely hard to read once you have a lot of values in there like you're predicting.
(Honestly, I didn't even know Version 2 was legal until now. I've never seen it done that way before.)

I'm not sure there is point in such conversion (yes, many do it, but mostly to force a square peg through round hole) -- there is structural impedance mismatch, and conversion is lossy. So I would recommend against such format-to-format transformations.
But if you do it, first convert from json to object, then from object to xml (and vice versa for reverse direction). Doing direct transformation leads to ugly output, loss of information, or possibly both.
If you include ALL references to the spreadsheet data in the UDF parameter list, Excel will recalculate your function whenever the referenced data changes:
Public Function doubleMe(d As Variant)
doubleMe = d * 2
End Function
You can also use Application.Volatile
, but this has the disadvantage of making your UDF always recalculate - even when it does not need to because the referenced data has not changed.
Public Function doubleMe()
Application.Volatile
doubleMe = Worksheets("Fred").Range("A1") * 2
End Function
Use MyISAM for very unimportant data or if you really need those minimal performance advantages. The read performance is not better in every case for MyISAM.
I would personally never use MyISAM at all anymore. Choose InnoDB and throw a bit more hardware if you need more performance. Another idea is to look at database systems with more features like PostgreSQL if applicable.
EDIT: For the read-performance, this link shows that innoDB often is actually not slower than MyISAM: https://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1/
How about you store it like this? Maybe in username:password format, so
sebastion:password123
anotheruser:password321
Then you can use list($username,$password) = explode(':',file_get_contents('users.txt'));
to parse the data on your end.
-Contains
is actually a collection operator. It is true if the collection contains the object. It is not limited to strings.
-match
and -imatch
are regular expression string matchers, and set automatic variables to use with captures.
-like
, -ilike
are SQL-like matchers.
As mentioned in the github issue originally linked by @peter in the comments:
const freshFruits = (fruits as (Apple | Pear)[]).filter((fruit: (Apple | Pear)) => !fruit.isDecayed);
Consider the tricks that <a href> knows by default but javascript linking won't do for you. On a decent website, anything that wants to behave as a link should implement these features one way or another. Namely:
Now if you don't want to simulate all that behaviour, I suggest to use <a href> and style it like a button, since the button itself is roughly a shape and a hover effect. I think if it's not semantically important to only have "the button and nothing else", <a href> is the way of the samurai. And if you worry about semantics and readability, you can also replace the button element when your document is ready(). It's clear and safe.
Simple one line command to get rid of it, type below command in terminal,

Snippet from http://msdn.microsoft.com/en-us/library/aa214566(office.11).aspx
you need to use backslash before ". like \"
From the doc here you can see that
A character preceded by a backslash ( \ ) is an escape sequence and has special meaning to the compiler.
and " (double quote) is a escacpe sequence
When an escape sequence is encountered in a print statement, the compiler interprets it accordingly. For example, if you want to put quotes within quotes you must use the escape sequence, \", on the interior quotes. To print the sentence
She said "Hello!" to me.
you would write
System.out.println("She said \"Hello!\" to me.");
You can do the same in Razor or in the Controller, like so..
@{
//do this on the top most of your View, immediately after `using` statement
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");
}
Or in the Controller..
public ActionResult Receipt() {
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");
return View();
}
I tried this in Chrome and IE9, both is downloading the pdf file.
I probably should add I am using RazorPDF to generate my PDFs. Here is a blog about it: http://nyveldt.com/blog/post/Introducing-RazorPDF
There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple
To shorten it up a little:
geocoder = new google.maps.Geocoder();
function codeAddress() {
//In this case it gets the address from an element on the page, but obviously you could just pass it to the method instead
var address = document.getElementById( 'address' ).value;
geocoder.geocode( { 'address' : address }, function( results, status ) {
if( status == google.maps.GeocoderStatus.OK ) {
//In this case it creates a marker, but you can get the lat and lng from the location.LatLng
map.setCenter( results[0].geometry.location );
var marker = new google.maps.Marker( {
map : map,
position: results[0].geometry.location
} );
} else {
alert( 'Geocode was not successful for the following reason: ' + status );
}
} );
}
<script>
var today = new Date;
document.getElementById('date').innerHTML= today.toDateString();
</script>
As mentioned in Jonathan's answer, FETCH_HEAD corresponds to the file .git/FETCH_HEAD
. Typically, the file will look like this:
71f026561ddb57063681109aadd0de5bac26ada9 branch 'some-branch' of <remote URL>
669980e32769626587c5f3c45334fb81e5f44c34 not-for-merge branch 'some-other-branch' of <remote URL>
b858c89278ab1469c71340eef8cf38cc4ef03fed not-for-merge branch 'yet-some-other-branch' of <remote URL>
Note how all branches but one are marked not-for-merge
. The odd one out is the branch that was checked out before the fetch. In summary: FETCH_HEAD essentially corresponds to the remote version of the branch that's currently checked out.
In order to use base_url()
, you must first have the URL Helper loaded. This can be done either in application/config/autoload.php
(on or around line 67):
$autoload['helper'] = array('url');
Or, manually:
$this->load->helper('url');
Once it's loaded, be sure to keep in mind that base_url()
doesn't implicitly print or echo out anything, rather it returns the value to be printed:
echo base_url();
Remember also that the value returned is the site's base url as provided in the config file. CodeIgniter will accomodate an empty value in the config file as well:
If this (base_url) is not set then CodeIgniter will guess the protocol, domain and path to your installation.

my py version is 3.7.3, and this cmd worked

This runs the pip module and asks it to find the requests library on PyPI.org (the Python Package Index) and install it in your local system so that it becomes available for you to import
As others have said, you have to implement your own TryParse
. Simon Mourier is providing a full implementation which takes care of everything.
If you are using bitfield enums (i.e. flags), you also have to handle a string like "MyEnum.Val1|MyEnum.Val2"
which is a combination of two enum values. If you just call Enum.IsDefined
with this string, it will return false, even though Enum.Parse
handles it correctly.
Update
As mentioned by Lisa and Christian in the comments, Enum.TryParse
is now available for C# in .NET4 and up.

//Return the string
return sValue;

My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.
You don't really need any JavaScript with Bootstrap:
<ul class="nav">
<li><a data-target="#" data-toggle="pill" href="#accounts">Accounts</a></li>
<li><a data-target="#" data-toggle="pill" href="#users">Users</a></li>
</ul>
To do more tasks after the menu item is selected you need JS as explained by other posts here.
Hope this helps.
Try something like:
import pylab as p
p.plot(x,y)
p.axis('equal')
p.show()
Its pretty simple. I saved the mysql community server in my D:\
drive. Hence this is how i did it.
Goto D:\mysql-5.7.18-winx64\bin
and in the address bar type cmd and press enter, so command prompt will open. Now if you're using it for the first time type as mysql -u root -p
press enter. Then it will ask for password, again press enter. Thats it you are connected to the mysql server.
Before this make sure wamp or xampp any of the local server is running
because i couldn't able to connect to mysql wihthout xampp running.
Happy Coding.
You want reorder()
. Here is an example with dummy data
set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))
require("ggplot2")
p1 <- ggplot(df, aes(x = Category, y = Count)) +
geom_bar(stat = "identity")
p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
geom_bar(stat = "identity")
require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))
Giving:
Use reorder(Category, Count)
to have Category
ordered from low-high.
MD5 yields hexadecimal digits (0-15 / 0-F), so they are four bits each. 128 / 4 = 32 characters.
SHA-1 yields hexadecimal digits too (0-15 / 0-F), so 160 / 4 = 40 characters.
(Since they're mathematical operations, most hashing functions' output is commonly represented as hex digits.)
You were probably thinking of ASCII text characters, which are 8 bits.
I think you want to test
your RegExp in TypeScript, so you have to do like this:
var trigger = "2",
regexp = new RegExp('^[1-9]\d{0,2}$'),
test = regexp.test(trigger);
alert(test + ""); // will display true
You should read MDN Reference - RegExp, the RegExp
object accepts two parameters pattern
and flags
which is nullable(can be omitted/undefined). To test your regex you have to use the .test()
method, not passing the string you want to test inside the declaration of your RegExp!
Why test + ""
?
Because alert()
in TS accepts a string as argument, it is better to write it this way. You can try the full code here.
Although <input>
ignores the rows
attribute, you can take advantage of the fact that <textarea>
doesn't have to be inside <form>
tags, but can still be a part of a form by referencing the form's id:
<form method="get" id="testformid">
<input type="submit" />
</form>
<textarea form ="testformid" name="taname" id="taid" cols="35" wrap="soft"></textarea>
Of course, <textarea>
now appears below "submit" button, but maybe you'll find a way to reposition it.
As for adding a dependency, I'm afraid the java.util.Date & .Calendar really are so bad that the first thing I do to any new project is add the Joda-Time library. In Java 8 you can use the new java.time package, inspired by Joda-Time.
The core of Joda-Time is the DateTime
class. Unlike java.util.Date, it understands its assigned time zone (DateTimeZone
). When converting from j.u.Date, assign a zone.
DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime dateTimeQuébec = new DateTime( date , zone );
LocalDate
One way to verify if two date-times land on the same date is to convert to LocalDate
objects.
That conversion depends on the assigned time zone. To compare LocalDate
objects, they must have been converted with the same zone.
Here is a little utility method.
static public Boolean sameDate ( DateTime dt1 , DateTime dt2 )
{
LocalDate ld1 = new LocalDate( dt1 );
// LocalDate determination depends on the time zone.
// So be sure the date-time values are adjusted to the same time zone.
LocalDate ld2 = new LocalDate( dt2.withZone( dt1.getZone() ) );
Boolean match = ld1.equals( ld2 );
return match;
}
Better would be another argument, specifying the time zone rather than assuming the first DateTime object’s time zone should be used.
static public Boolean sameDate ( DateTimeZone zone , DateTime dt1 , DateTime dt2 )
{
LocalDate ld1 = new LocalDate( dt1.withZone( zone ) );
// LocalDate determination depends on the time zone.
// So be sure the date-time values are adjusted to the same time zone.
LocalDate ld2 = new LocalDate( dt2.withZone( zone ) );
return ld1.equals( ld2 );
}
Another approach is to create a string representation of the date portion of each date-time, then compare strings.
Again, the assigned time zone is crucial.
DateTimeFormatter formatter = ISODateTimeFormat.date(); // Static method.
String s1 = formatter.print( dateTime1 );
String s2 = formatter.print( dateTime2.withZone( dt1.getZone() ) );
Boolean match = s1.equals( s2 );
return match;
The generalized solution is to define a span of time, then ask if the span contains your target. This example code is in Joda-Time 2.4. Note that the "midnight"-related classes are deprecated. Instead use the withTimeAtStartOfDay
method. Joda-Time offers three classes to represent a span of time in various ways: Interval, Period, and Duration.
Using the "Half-Open" approach where the beginning of the span is inclusive and the ending exclusive.
The time zone of the target can be different than the time zone of the interval.
DateTimeZone timeZone = DateTimeZone.forID( "Europe/Paris" );
DateTime target = new DateTime( 2012, 3, 4, 5, 6, 7, timeZone );
DateTime start = DateTime.now( timeZone ).withTimeAtStartOfDay();
DateTime stop = start.plusDays( 1 ).withTimeAtStartOfDay();
Interval interval = new Interval( start, stop );
boolean containsTarget = interval.contains( target );
Java 8 and later comes with the java.time framework. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. See Tutorial.
The makers of Joda-Time have instructed us all to move to java.time as soon as is convenient. In the meantime Joda-Time continues as an actively maintained project. But expect future work to occur only in java.time and ThreeTen-Extra rather than Joda-Time.
To summarize java.time in a nutshell… An Instant
is a moment on the timeline in UTC. Apply a time zone (ZoneId
) to get a ZonedDateTime
object. To move off the timeline, to get the vague indefinite idea of a date-time, use the "local" classes: LocalDateTime
, LocalDate
, LocalTime
.
The logic discussed in the Joda-Time section of this Answer applies to java.time.
The old java.util.Date class has a new toInstant
method for conversion to java.time.
Instant instant = yourJavaUtilDate.toInstant(); // Convert into java.time type.
Determining a date requires a time zone.
ZoneId zoneId = ZoneId.of( "America/Montreal" );
We apply that time zone object to the Instant
to obtain a ZonedDateTime
. From that we extract a date-only value (a LocalDate
) as our goal is to compare dates (not hours, minutes, etc.).
ZonedDateTime zdt1 = ZonedDateTime.ofInstant( instant , zoneId );
LocalDate localDate1 = LocalDate.from( zdt1 );
Do the same to the second java.util.Date
object we need for comparison. I’ll just use the current moment instead.
ZonedDateTime zdt2 = ZonedDateTime.now( zoneId );
LocalDate localDate2 = LocalDate.from( zdt2 );
Use the special isEqual
method to test for the same date value.
Boolean sameDate = localDate1.isEqual( localDate2 );
Also, you can utilize crash dumps to debug your software. The customer sends it to you and then you can use it to identify the exact version of your source - and Visual Studio will even pull the right set of debugging symbols (and source if you're set up correctly) using the crash dump. See Microsoft's documentation on Symbol Stores.
I was looking for How to iterate on rows and columns and ended here so:
for i, row in df.iterrows():
for j, column in row.iteritems():
print(column)
Did you install/update the driver for the FTDI cable? (Step three on http://arduino.cc/en/Guide/Howto). Running the Arduino IDE from my Raspberry Pi worked fine without explicitly installing the drivers (either they were pre-installed or the Arduino IDE installer took care of it). On my Mac this was not the case and I had to install the cable drivers in addition to the IDE.
SQL> grant create any procedure to testdb;
This is a command when we want to give create privilege to "testdb" user.
Just to add to @Justin's answer above..
it should be
var rgb = document.querySelector('#selector').style['background-color'];
return '#' + rgb.substr(4, rgb.indexOf(')') - 4).split(',').map((color) => String("0" + parseInt(color).toString(16)).slice(-2)).join('');
As the above parse int functions truncates leading zeroes, thus produces incorrect color codes of 5 or 4 letters may be... i.e. for rgb(216, 160, 10) it produces #d8a0a while it should be #d8a00a.
Thanks
Warning: Unfortunately I believe most popular platforms have dropped support for comprehensions. See below for the well-supported ES6 method
You can always use something like:
[for (i of Array(7).keys()) i*i];
Running this code on Firefox:
[ 0, 1, 4, 9, 16, 25, 36 ]
This works on Firefox (it was a proposed ES7 feature), but it has been dropped from the spec. IIRC, Babel 5 with "experimental" enabled supports this.
This is your best bet as array-comprehension are used for just this purpose. You can even write a range function to go along with this:
var range = (u, l = 0) => [ for( i of Array(u - l).keys() ) i + l ]
Then you can do:
[for (i of range(5)) i*i] // 0, 1, 4, 9, 16, 25
[for (i of range(5,3)) i*i] // 9, 16, 25
A nice way to do this any of:
[...Array(7).keys()].map(i => i * i);
Array(7).fill().map((_,i) => i*i);
[...Array(7)].map((_,i) => i*i);
This will output:
[ 0, 1, 4, 9, 16, 25, 36 ]
@Entity
@NamedQuery(name = "Customer.listUniqueNames",
query = "SELECT DISTINCT c.name FROM Customer c")
public class Customer {
...
private String name;
public static List<String> listUniqueNames() {
return = getEntityManager().createNamedQuery(
"Customer.listUniqueNames", String.class)
.getResultList();
}
}
I've had the same problem with you.
cd to ../etc/ then use ls to make sure your "paths" file is in , vim paths, add "/usr/local/bin" at the end of the file.
You could use Extract Method. In other words extract that code into a method which you'd then call.
I wouldn't try to compress it much more, the one liners seem harder to read than the verbose version. And if you use Extract Method, it's a one liner ;)
I ran into something similar - I wanted to create a range based on some variables. Using the Worksheet.Cells did not work directly since I think the cell's values were passed to Range.
This did work though:
Range(Cells(1, 1).Address(), Cells(lastRow, lastColumn).Address()).Select
That took care of converting the cell's numerical location to what Range expects, which is the A1 format.
Once I changed Options -Index
to Options +Index
in my conf file, I removed the welcome page and restarted services.
$ sudo rm -f /etc/httpd/conf.d/welcome.conf
$ sudo service httpd restart
I was able to see directory listings after that.
I would suggest that you start with some sort of placeholder, you may have this already, but its somewhere to append the div.
<div id="placeholder"></div>
Now, the idea is to dynamically create a new div, with your random id:
var rndId = randomString(8);
var div = document.createElement('div');
div.id = rndId
div.innerHTML = "Whatever you want the content of your div to be";
this can be apended to your placeholder as follows:
document.getElementById('placeholder').appendChild(div);
You can then use that in your jwplayer code:
jwplayer(rndId).setup(...);
Live example: http://jsfiddle.net/pNYZp/
Sidenote: Im pretty sure id's must start with an alpha character (ie, no numbers) - you might want to change your implementation of randomstring to enforce this rule. (ref)
If you open a device using png()
, bmp()
, pdf()
etc. as suggested by Andrie (the best answer), the windows with plots will not pop up open, just *.png, *bmp or *.pdf files will be created. This is convenient in massive calculations, since R can handle only limited number of graphic windows.
However, if you want to see the plots and also have them saved, call savePlot(filename, type)
after the plots are drawn and the window containing them is active.
You can use the next extensions which are based on a predicate condition:
/// <summary>
/// Find an index of a first element that satisfies <paramref name="match"/>
/// </summary>
/// <typeparam name="T">Type of elements in the source collection</typeparam>
/// <param name="this">This</param>
/// <param name="match">Match predicate</param>
/// <returns>Zero based index of an element. -1 if there is not such matches</returns>
public static int IndexOf<T>(this IList<T> @this, Predicate<T> match)
{
@this.ThrowIfArgumentIsNull();
match.ThrowIfArgumentIsNull();
for (int i = 0; i < @this.Count; ++i)
if (match(@this[i]))
return i;
return -1;
}
/// <summary>
/// Replace the first occurance of an oldValue which satisfies the <paramref name="removeByCondition"/> by a newValue
/// </summary>
/// <typeparam name="T">Type of elements of a target list</typeparam>
/// <param name="this">Source collection</param>
/// <param name="removeByCondition">A condition which decides is a value should be replaced or not</param>
/// <param name="newValue">A new value instead of replaced</param>
/// <returns>This</returns>
public static IList<T> Replace<T>(this IList<T> @this, Predicate<T> replaceByCondition, T newValue)
{
@this.ThrowIfArgumentIsNull();
removeByCondition.ThrowIfArgumentIsNull();
int index = @this.IndexOf(replaceByCondition);
if (index != -1)
@this[index] = newValue;
return @this;
}
/// <summary>
/// Replace all occurance of values which satisfy the <paramref name="removeByCondition"/> by a newValue
/// </summary>
/// <typeparam name="T">Type of elements of a target list</typeparam>
/// <param name="this">Source collection</param>
/// <param name="removeByCondition">A condition which decides is a value should be replaced or not</param>
/// <param name="newValue">A new value instead of replaced</param>
/// <returns>This</returns>
public static IList<T> ReplaceAll<T>(this IList<T> @this, Predicate<T> replaceByCondition, T newValue)
{
@this.ThrowIfArgumentIsNull();
removeByCondition.ThrowIfArgumentIsNull();
for (int i = 0; i < @this.Count; ++i)
if (replaceByCondition(@this[i]))
@this[i] = newValue;
return @this;
}
Notes: - Instead of ThrowIfArgumentIsNull extension, you can use a general approach like:
if (argName == null) throw new ArgumentNullException(nameof(argName));
So your case with these extensions can be solved as:
string targetString = valueFieldValue.ToString();
listofelements.Replace(x => x.Equals(targetString), value.ToString());
One liner:
<? if (have_posts()):while(have_posts()): the_post(); the_content(); endwhile; endif; ?>
The problem is that the second part of your substring argument is including the first index. You need to subtract the first index from your second index to make this work.
SELECT SUBSTRING(@Text, CHARINDEX('the dog', @Text)
, CHARINDEX('immediately',@text) - CHARINDEX('the dog', @Text) + Len('immediately'))
Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.
git rebase the-branch-to-be-merged
I solved the problem using this git command, but rebase
is only suited for some cases.
>>> import datetime
>>> now = datetime.datetime.now()
>>> now.strftime("%B %d, %Y")

useState is a hook that lets you add state to a functional component. It accepts an argument which is the initial value of the state property and returns the current value of state property and a method which is capable of updating that state property.
Following is a simple example:
import React, {useState} from react
function HookCounter {
const [count, stateCount]= useState(0)
return(
<div>
<button onClick{( ) => setCount(count+1)}> count{count}</button>
</div>
)
}
useState accepts the initial value of the state variable which is zero in this case and returns a pair of values. The current value of the state has been called count and a method that can update the state variable has been called as setCount.
With recent version of Pandas, you can do
df.N.hist(by=df.Letter)
Just like with the solutions above, the axes will be different for each subplot. I have not solved that one yet.
Hey guys it exist a much more sexy tool for a developper to have a look into a Directory, whatever the Directory is (Active-Directory, OpenLDAP, eDirectory ...) its name is Apache Directory studio, it works in the same way on the top of java in Windows or in Linux. It's a kind of universal LDP.EXE for those who know this tool on Windows Servers. It allows to create LDIF files and also to browse the SCHEMA.
This will return default size of text on button in pixels.
val size = Button(this).textSize
float size = new Button(this).getTextSize();
This solution works if you're using chrome (can't verify other browsers) and if the text is located in the same DOM Element:
window.getSelection().anchorNode.textContent.substring(
window.getSelection().extentOffset,
window.getSelection().anchorOffset)
In ES6, you can just use myFunction.name
.
Note: Beware that some JS minifiers might throw away function names, to compress better; you may need to tweak their settings to avoid that.
In ES5, the best thing to do is:
function functionName(fun) {
var ret = fun.toString();
ret = ret.substr('function '.length);
ret = ret.substr(0, ret.indexOf('('));
return ret;
}
Using Function.caller
is non-standard. Function.caller
and arguments.callee
are both forbidden in strict mode.
Edit: nus's regex based answer below achieves the same thing, but has better performance!
To make it all inline (non-recursive):
{str(k):(str(v) if isinstance(v, unicode) else v) for k,v in my_dict.items()}
You can use Named Sections.
_Layout.cshtml
<head>
<script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
@RenderSection("JavaScript", required: false)
</head>
_SomeView.cshtml
@section JavaScript
{
<script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
<script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}
Have you tried to see if there is any white space on the right of your report? If so you can drag it back to the end of your report and then drag the report background back to the same spot.
I think CAST(ROUND(yourColumn,2) as varchar)
should do the job.
But why do you want to do this presentational formatting in T-SQL?
mvn install "-Dsomeproperty=propety value"
In pom.xml:
<properties>
<someproperty> ${someproperty} </someproperty>
</properties>
