I FIGURED IT OUT. SIMPLE, EFFECTIVE NO jQUERY
We're going to to be using a hidden checkbox.
This example includes one "on click - off click 'hover / active' state"
--
To make content itself clickable:
#activate-div{display:none}
.my-div{background-color:#FFF}
#activate-div:checked ~ label
.my-div{background-color:#000}
_x000D_
<input type="checkbox" id="activate-div">
<label for="activate-div">
<div class="my-div">
//MY DIV CONTENT
</div>
</label>
_x000D_
To make button change content:
#activate-div{display:none}
.my-div{background-color:#FFF}
#activate-div:checked +
.my-div{background-color:#000}
_x000D_
<input type="checkbox" id="activate-div">
<div class="my-div">
//MY DIV CONTENT
</div>
<label for="activate-div">
//MY BUTTON STUFF
</label>
_x000D_
Hope it helps!!
I ran into this and what worked for me was to run yum localinstall enterPkgNameHere.rpm
from inside the directory where the .rpm file is located.
Note: replace the enterPkgNameHere.rpm
with the name of your .rpm file.
Try
SELECT * FROM table WHERE arr @> ARRAY['s']::varchar[]
I cannot agree with arguments, that it is better to write all files in other directories, e.g., %APPDATA%, it is only that you cannot avoid it, if you want to avoid running application as administrator on Windows 7.
It would be much cleaner to keep all application specific data (e.g. ini files) in the same folder as the application (or in sub folders) as to speed the data all over the disk (%APPDATA%, registry and who knows where else). This is just Microsoft idea of clean programming. Than of course you need registry cleaner, disk cleaner, temporary file cleaner, ... instead of e+very clean practice - removing the application folder removes all application specific data (exep user data, which is normally somewhere in My Documents or so).
In my programs I would prefer to have ini files in application directory, however, I do not have them there, only because I cannot have them there (on Windows).
The thing to look at is what HTML is being spit out by the control. In this case it puts out a table to create the menu. The hover style is set on the TD and once you select a menu item the control posts back and adds the selected style to the A tag of the link within the TD.
So you have two different items that are being manipulated here. One is a TD element and another is an A element. So, you have to make your CSS work accordingly. If I add the below CSS to a page with the menu then I get the expected behavior of the background color changing in either case. You may be doing some different CSS manipulation that may or may not apply to those elements.
<style>
.StaticHoverStyle
{
background: #000000;
}
.StaticSelectedStyle
{
background: blue;
}
</style>

Dialect means "the variant of a language". Hibernate, as we know, is database agnostic. It can work with different databases. However, databases have proprietary extensions/native SQL variations, and set/sub-set of SQL standard implementations. Therefore at some point hibernate has to use database specific SQL. Hibernate uses "dialect" configuration to know which database you are using so that it can switch to the database specific SQL generator code wherever/whenever necessary.
Ok! Here is the thing, it is more Secure to have your DB Server installed on another Machine and your Application on the Web Server. You then connect your application to the DB with a Web Link. Thanks it.
Problem is, you're trying to upcast to a richer object. You simply need to add the items to a new list:
if (myObject is IEnumerable)
{
List<object> list = new List<object>();
var enumerator = ((IEnumerable) myObject).GetEnumerator();
while (enumerator.MoveNext())
{
list.Add(enumerator.Current);
}
}
conda
insteadNone of the proposed solutions worked for me on Raspbian 10 (buster)
so I just installed it via conda
and voila:
conda install -c anaconda cryptography
P.S. : I know that the question mentions pip
but I see that OP is using a conda
installation so I thought of sharing this solution anyway. Nevertheless, since this problem is apparently OS-specific, it's meaningful to remind one that conda
is a cross-platform and language-agnostic solution which may also install necessary binaries apart from python
packages - with just an one-liner.
This is a lexicographical ordering. It just puts things in dictionary order.
There is a Date function.
Lets assume you have data in D and E cells.. Here is an easiest ratio displaying fn by my frnd 'Karthik'
=ROUND(D7/E7, 2) &":" & (E7/E7)
Create a file named filesize.cmd (and put into folder C:\Windows\System32):
@echo %~z1
When using Rails 5 (currently still in beta), there's a new method, parsed_body
on the test response, which will return the response parsed as what the last request was encoded at.

I don't believe there's any way to get a cell's color from a formula. The closest you can get is the CELL
formula, but (at least as of Excel 2003), it doesn't return the cell's color.
It would be pretty easy to implement with VBA:
Public Function myColor(r As Range) As Integer
myColor = r.Interior.ColorIndex
End Function
Then in the worksheet:
=mycolor(A1)
function getdatetime() {
d = new Date();
return (1e3-~d.getUTCMonth()*10+d.toUTCString()+1e3+d/1)
.replace(/1(..)..*?(\d+)\D+(\d+).(\S+).*(...)/,'$3-$1-$2T$4.$5Z')
.replace(/-(\d)T/,'-0$1T');
}
I found the basics on Stack Overflow somewhere (I believe it was part of some other Stack Exchange code golfing), and I improved it so it works on Internet Explorer 10 or earlier as well. It's ugly, but it gets the job done.
If you're using C#, it would be driver.Displayed. Here's an example from my own project:
if (!driver.FindElement(By.Name("newtagfield")).Displayed) //if the tag options is not displayed
driver.FindElement(By.Id("expand-folder-tags")).Click(); //make sure the folder and tags options are visible
There are many valid answers already but I'd like to add anther implementation as a Type extension and a list of unit tests to demonstrate different scenarios:
public static class TypeExtensions
{
public static IEnumerable<Type> GetAllTypes(this Type type)
{
var typeInfo = type.GetTypeInfo();
var allTypes = GetAllImplementedTypes(type).Concat(typeInfo.ImplementedInterfaces);
return allTypes;
}
private static IEnumerable<Type> GetAllImplementedTypes(Type type)
{
yield return type;
var typeInfo = type.GetTypeInfo();
var baseType = typeInfo.BaseType;
if (baseType != null)
{
foreach (var foundType in GetAllImplementedTypes(baseType))
{
yield return foundType;
}
}
}
}
This algorithm supports the following scenarios:

If you have jQuery enabled you can use an escapeXml function and not have to worry about escaping arrows or special characters.
<pre>
${fn:escapeXml('

')};
</pre>
If you're looking to change the title text size and the text color you have to change the NSDictionary titleTextAttributes, for 2 of its objects:
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:13.0],NSFontAttributeName,
[UIColor whiteColor], NSForegroundColorAttributeName,
nil];
I generally store my macros in xlam
add-ins separately from my workbooks so I wanted to open a workbook and then run a macro stored separately.
Since this required a VBS Script, I wanted to make it "portable" so I could use it by passing arguments. Here is the final script, which takes 3 arguments.
I tested it like so:
"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlam" "Hello"
"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlsx" "Hello" "%AppData%\Microsoft\Excel\XLSTART\Book1.xlam"
runmacro.vbs:
Set args = Wscript.Arguments
ws = WScript.Arguments.Item(0)
macro = WScript.Arguments.Item(1)
If wscript.arguments.count > 2 Then
macrowb= WScript.Arguments.Item(2)
End If
LaunchMacro
Sub LaunchMacro()
Dim xl
Dim xlBook
Set xl = CreateObject("Excel.application")
Set xlBook = xl.Workbooks.Open(ws, 0, True)
If wscript.arguments.count > 2 Then
Set macrowb= xl.Workbooks.Open(macrowb, 0, True)
End If
'xl.Application.Visible = True ' Show Excel Window
xl.Application.run macro
'xl.DisplayAlerts = False ' suppress prompts and alert messages while a macro is running
'xlBook.saved = True ' suppresses the Save Changes prompt when you close a workbook
'xl.activewindow.close
xl.Quit
End Sub
In bash version 4 associative arrays were introduced.
declare -A arr
arr["key1"]=val1
arr+=( ["key2"]=val2 ["key3"]=val3 )
The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.
for key in ${!arr[@]}; do
echo ${key} ${arr[${key}]}
done
Will loop over all key values and echo them out.
Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here
Use the wait
built-in:
process1 &
process2 &
process3 &
process4 &
wait
process5 &
process6 &
process7 &
process8 &
wait
For the above example, 4 processes process1
... process4
would be started in the background, and the shell would wait until those are completed before starting the next set.
From the GNU manual:
wait [jobspec or pid ...]
Wait until the child process specified by each process ID pid or job specification jobspec exits and return the exit status of the last command waited for. If a job spec is given, all processes in the job are waited for. If no arguments are given, all currently active child processes are waited for, and the return status is zero. If neither jobspec nor pid specifies an active child process of the shell, the return status is 127.
I found very good explanation about .la files here http://openbooks.sourceforge.net/books/wga/dealing-with-libraries.html
Summary (The way I understood): Because libtool deals with static and dynamic libraries internally (through --diable-shared or --disable-static) it creates a wrapper on the library files it builds. They are treated as binary library files with in libtool supported environment.
This is PKCS#1 format of a private key. Try this code. It doesn't use Bouncy Castle or other third-party crypto providers. Just java.security and sun.security for DER sequece parsing. Also it supports parsing of a private key in PKCS#8 format (PEM file that has a header "-----BEGIN PRIVATE KEY-----").

Spring AOP and annotation based solution:
Usage (@RetryOperation
is our custom annotation for the job):
@RetryOperation(retryCount = 1, waitSeconds = 10)
boolean someMethod() throws Exception {
}
We'll need two things to accomplish this: 1. an annotation interface, and 2. a spring aspect. Here's one way to implement these:
The Annotation Interface:
import java.lang.annotation.*;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface RetryOperation {
int retryCount();
int waitSeconds();
}
The Spring Aspect:
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.reflect.MethodSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import java.lang.reflect.Method;
@Aspect @Component
public class RetryAspect {
private static final Logger LOGGER = LoggerFactory.getLogger(RetryAspect.class);
@Around(value = "@annotation(RetryOperation)")
public Object retryOperation(ProceedingJoinPoint joinPoint) throws Throwable {
Object response = null;
Method method = ((MethodSignature) joinPoint.getSignature()).getMethod();
RetryOperation annotation = method.getAnnotation(RetryOperation.class);
int retryCount = annotation.retryCount();
int waitSeconds = annotation.waitSeconds();
boolean successful = false;
do {
try {
response = joinPoint.proceed();
successful = true;
} catch (Exception ex) {
LOGGER.info("Operation failed, retries remaining: {}", retryCount);
retryCount--;
if (retryCount < 0) {
throw ex;
}
if (waitSeconds > 0) {
LOGGER.info("Waiting for {} second(s) before next retry", waitSeconds);
Thread.sleep(waitSeconds * 1000l);
}
}
} while (!successful);
return response;
}
}
We have 2 ways by which we can rename a file on AWS S3 storage -
1 .Using the CLI tool -
aws s3 --recursive mv s3://bucket-name/dirname/oldfile s3://bucket-name/dirname/newfile
2.Using SDK
$s3->copyObject(array(
'Bucket' => $targetBucket,
'Key' => $targetKeyname,
'CopySource' => "{$sourceBucket}/{$sourceKeyname}",));
After resizing and not being able to view the resizing on my windows XP guest machine, I had to

For resizing outside windows, a gparted boot cd that can be found here can help
I'm using a simpler method:
The navigator global object has a property touchpoints, in Internet Exlorer 11 is called msMaxTouchPoints tho.
So if you look for:
navigator.msMaxTouchPoints !== void 0
You will find Internet Explorer 11.
If you want to initialize an array in a constructor, you can't use those array initializer like.
data= {10,20,30,40,50,60,71,80,90,91};
Just change it to
data = new int[] {10,20,30,40,50,60,71,80,90,91};
You don't have to specify the size with data[10] = new int[] { 10,...,91}
Just declare the property / field with int[] data;
and initialize it like above.
The corrected version of your code would look like the following:
public class Array {
int[] data;
public Array() {
data = new int[] {10,20,30,40,50,60,71,80,90,91};
}
}
As you see the bracket are empty. There isn't any need to tell the size between the brackets, because the initialization and its size are specified by the count of the elements between the curly brackets.

I design & implemented a simple finite state machine example with java.
IFiniteStateMachine: The public interface to manage the finite state machine
such as add new states to the finite state machine or transit to next states by
specific actions.
interface IFiniteStateMachine {
void setStartState(IState startState);
void setEndState(IState endState);
void addState(IState startState, IState newState, Action action);
void removeState(String targetStateDesc);
IState getCurrentState();
IState getStartState();
IState getEndState();
void transit(Action action);
}
IState: The public interface to get state related info
such as state name and mappings to connected states.
interface IState {
// Returns the mapping for which one action will lead to another state
Map<String, IState> getAdjacentStates();
String getStateDesc();
void addTransit(Action action, IState nextState);
void removeTransit(String targetStateDesc);
}
Action: the class which will cause the transition of states.
public class Action {
private String mActionName;
public Action(String actionName) {
mActionName = actionName;
}
String getActionName() {
return mActionName;
}
@Override
public String toString() {
return mActionName;
}
}
StateImpl: the implementation of IState. I applied data structure such as HashMap to keep Action-State mappings.
public class StateImpl implements IState {
private HashMap<String, IState> mMapping = new HashMap<>();
private String mStateName;
public StateImpl(String stateName) {
mStateName = stateName;
}
@Override
public Map<String, IState> getAdjacentStates() {
return mMapping;
}
@Override
public String getStateDesc() {
return mStateName;
}
@Override
public void addTransit(Action action, IState state) {
mMapping.put(action.toString(), state);
}
@Override
public void removeTransit(String targetStateDesc) {
// get action which directs to target state
String targetAction = null;
for (Map.Entry<String, IState> entry : mMapping.entrySet()) {
IState state = entry.getValue();
if (state.getStateDesc().equals(targetStateDesc)) {
targetAction = entry.getKey();
}
}
mMapping.remove(targetAction);
}
}
FiniteStateMachineImpl: Implementation of IFiniteStateMachine. I use ArrayList to keep all the states.
public class FiniteStateMachineImpl implements IFiniteStateMachine {
private IState mStartState;
private IState mEndState;
private IState mCurrentState;
private ArrayList<IState> mAllStates = new ArrayList<>();
private HashMap<String, ArrayList<IState>> mMapForAllStates = new HashMap<>();
public FiniteStateMachineImpl(){}
@Override
public void setStartState(IState startState) {
mStartState = startState;
mCurrentState = startState;
mAllStates.add(startState);
// todo: might have some value
mMapForAllStates.put(startState.getStateDesc(), new ArrayList<IState>());
}
@Override
public void setEndState(IState endState) {
mEndState = endState;
mAllStates.add(endState);
mMapForAllStates.put(endState.getStateDesc(), new ArrayList<IState>());
}
@Override
public void addState(IState startState, IState newState, Action action) {
// validate startState, newState and action
// update mapping in finite state machine
mAllStates.add(newState);
final String startStateDesc = startState.getStateDesc();
final String newStateDesc = newState.getStateDesc();

This short little line of code will give you the output you want.
If your column name has spaces you can use

I thought there were a few perfectly fine answers, but no concise summary of all possibilities; thus:
The core principal behind most answers here is redirection. Two are important redirection operators for writing to files:
echo 'text to completely overwrite contents of myfile' > myfile
echo 'text to add to end of myfile' >> myfile
Others mentioned, rather than from a fixed input source like echo 'text'
, you could also interactively write to files via a "Here Document", which are also detailed in the link to the bash manual above. Those answers, e.g.
cat > FILE.txt <<EOF
or cat >> FILE.txt <<EOF
make use of the same redirection operators, but add another layer via "Here Documents". In the above syntax, you write to the FILE.txt via the output of cat
. The writing only takes place after the interactive input is given some specific string, in this case 'EOF', but this could be any string, e.g.:
cat > FILE.txt <<'StopEverything'
or cat >> FILE.txt <<'StopEverything'
would work just as well. Here Documents also look for various delimiters and other interesting parsing characters, so have a look at the docs for further info on that.
A bit convoluted, and more of an exercise in understanding both redirection and Here Documents syntax, but you could combine Here Document style syntax with standard redirect operators to become a Here String:
Redirecting Output of cat Inputcat > myfile <<<'text to completely overwrite contents of myfile'
cat >> myfile <<<'text to completely overwrite contents of myfile'
"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.
In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

Because python 3 print() function allows end="" definition, that satisfies the majority of issues.
In my case, I wanted to PrettyPrint and was frustrated that this module wasn't similarly updated. So i made it do what i wanted:
from pprint import PrettyPrinter
class CommaEndingPrettyPrinter(PrettyPrinter):
def pprint(self, object):
self._format(object, self._stream, 0, 0, {}, 0)
# this is where to tell it what you want instead of the default "\n"
self._stream.write(",\n")
def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None):
"""Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end."""
printer = CommaEndingPrettyPrinter(
stream=stream, indent=indent, width=width, depth=depth)
printer.pprint(object)
Now, when I do:
comma_ending_prettyprint(row, stream=outfile)
I get what I wanted (substitute what you want -- Your Mileage May Vary)
I found that with curl 7.18.2 the download progress bar is not hidden with:

I know this is an old question, but I wanted to make sure a couple of other options are noted.
Since you can't store a TimeSpan greater than 24 hours in a time sql datatype field; a couple of other options might be.
Use a varchar(xx) to store the ToString of the TimeSpan. The benefit of this is the precision doesn't have to be baked into the datatype or the calculation, (seconds vs milliseconds vs days vs fortnights) All you need to to is use TimeSpan.Parse/TryParse. This is what I would do.
Use a second date, datetime or datetimeoffset, that stores the result of first date + timespan. Reading from the db is a matter of TimeSpan x = SecondDate - FirstDate. Using this option will protect you for other non .NET data access libraries access the same data but not understanding TimeSpans; in case you have such an environment.
I hope you are trying to run the main class in this way, see screenshot:
If not, then try this way. If yes, then please make sure that your class you are trying to run has a main method, that is, the same method definition as below:
public static void main(String[] args) {
// some code here
}
I hope this will help you.
Creating a new branch solved for me:
git checkout -b <nameOfNewBranch>
As expected no need to merge since previous branch was fully contained in the new one.
First, ensure that your version of Eclipse and JDK match, either both 64-bit or both 32-bit (you can't mix-and-match 32-bit with 64-bit).
Second, the -vm argument in eclipse.ini
should point to the java executable. See
http://wiki.eclipse.org/Eclipse.ini for examples.
If you're unsure of what version (64-bit or 32-bit) of Eclipse you have installed, you can determine that a few different ways. See How to find out if an installed Eclipse is 32 or 64 bit version?

You should use DecimalFormat("0.#")
For 4.3000
Double price = 4.3000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));
output is:
4.3
In case of 5.000 we have
Double price = 5.000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));
And the output is:

You can do this a few ways. One, simply add this meta tag to your head
:
<meta http-equiv="Cache-control" content="no-cache">
If you want to remove the document from cache, expires
meta tag should work to delete it by setting its content
attribute to -1
like so:
<meta http-equiv="Expires" content="-1">
http://www.metatags.org/meta_http_equiv_cache_control
Also, IE should give you the latest content for the main page. If you are having issues with external documents, like CSS and JS, add a dummy param at the end of your URLs with the current time in milliseconds so that it's never the same. This way IE, and other browsers, will always serve you the latest version. Here is an example:
<script src="mysite.com/js/myscript.js?12345">
UPDATE 1
After reading the comments I realize you wanted to programmatically erase the cache and not every time. What you could do is have a function in JS like:
eraseCache(){
window.location = window.location.href+'?eraseCache=true';
}
Then, in PHP let's say, you do something like this:
<head>
<?php
if (isset($_GET['eraseCache'])) {
echo '<meta http-equiv="Cache-control" content="no-cache">';
echo '<meta http-equiv="Expires" content="-1">';
$cache = '?' . time();
}
?>
<!-- ... other head HTML -->
<script src="mysite.com/js/script.js<?= $cache ?>"
</head>
This isn't tested, but should work. Basically, your JS function, if invoked, will reload the page, but adds a GET param to the end of the URL. Your site would then have some back-end code that looks for this param. If it exists, it adds the meta tags and a cache variable that contains a timestamp and appends it to the scripts and CSS that you are having caching issues with.
UPDATE 2
The meta tag indeed won't erase the cache on page load. So, technically you would need to run the eraseCache function in JS, once the page loads, you would need to load it again for the changes to take place. You should be able to fix this with your server side language. You could run the same eraseCache JS function, but instead of adding the meta tags, you need to add HTTP Cache headers:
<?php
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
?>
<!-- Here you'd start your page... -->
This method works immediately without the need for page reload because it erases the cache before the page loads and also before anything is run.

DECIMAL
has two parts: Precision
and Scale
. So part of your query will look like this:
CAST((COUNT(*) * 1.5) AS DECIMAL(8,2))
Precision
represents the number of significant digits that are stored for values.
Scale
represents the number of digits that can be stored following the decimal point.
To clarify the excellent answer of Ryan Newsom and to adjust it for fragments and for the usual case that we want to navigate from a "master" ListView fragment to a "details" fragment and then back to the "master"
private View root;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
if(root == null){
root = inflater.inflate(R.layout.myfragmentid,container,false);
InitializeView();
}
return root;
}
public void InitializeView()
{
ListView listView = (ListView)root.findViewById(R.id.listviewid);
BaseAdapter adapter = CreateAdapter();//Create your adapter here
listView.setAdpater(adapter);
//other initialization code
}
The "magic" here is that when we navigate back from the details fragment to the ListView fragment, the view is not recreated, we don't set the ListView's adapter, so everything stays as we left it!
Many of the answers here focus on the paths the compiler will search in order to find the file. While this is what most compilers do, a conforming compiler is allowed to be preprogrammed with the effects of the standard headers, and to treat, say, #include <list>
as a switch, and it need not exist as a file at all.
This is not purely hypothetical. There is at least one compiler that work that way. Using #include <xxx>
only with standard headers is recommended.
px
? PixelsAll of these answers seem to be incorrect. Contrary to intuition, in CSS the px
is not pixels. At least, not in the simple physical sense.
Read this article from the W3C, EM, PX, PT, CM, IN…, about how px
is a "magical" unit invented for CSS. The meaning of px
varies by hardware and resolution. (That article is fresh, last updated 2014-10.)
My own way of thinking about it: 1 px is the size of a thin line intended by a designer to be barely visible.
To quote that article:
The px unit is the magic unit of CSS. It is not related to the current font and also not related to the absolute units. The px unit is defined to be small but visible, and such that a horizontal 1px wide line can be displayed with sharp edges (no anti-aliasing). What is sharp, small and visible depends on the device and the way it is used: do you hold it close to your eyes, like a mobile phone, at arms length, like a computer monitor, or somewhere in between, like a book? The px is thus not defined as a constant length, but as something that depends on the type of device and its typical use.
To get an idea of the appearance of a px, imagine a CRT computer monitor from the 1990s: the smallest dot it can display measures about 1/100th of an inch (0.25mm) or a little more. The px unit got its name from those screen pixels.
Nowadays there are devices that could in principle display smaller sharp dots (although you might need a magnifier to see them). But documents from the last century that used px in CSS still look the same, no matter what the device. Printers, especially, can display sharp lines with much smaller details than 1px, but even on printers, a 1px line looks very much the same as it would look on a computer monitor. Devices change, but the px always has the same visual appearance.
That article gives some guidance about using pt
vs px
vs em
, to answer this Question.
I took a bit of time to work out what is the best way of doing this. I also wanted to keep the state, when the user leaves the page and then presses the back button, to get back to the old page; and not just put all my data into the rootscope.
The final result is to have a service for each controller. In the controller, you just have functions and variables that you dont care about, if they are cleared.
The service for the controller is injected by dependency injection. As services are singletons, their data is not destroyed like the data in the controller.
In the service, I have a model. the model ONLY has data - no functions -. That way it can be converted back and forth from JSON to persist it. I used the html5 localstorage for persistence.
Lastly i used window.onbeforeunload
and $rootScope.$broadcast('saveState');
to let all the services know that they should save their state, and $rootScope.$broadcast('restoreState')
to let them know to restore their state ( used for when the user leaves the page and presses the back button to return to the page respectively).
Example service called userService for my userController :
app.factory('userService', ['$rootScope', function ($rootScope) {
var service = {
model: {
name: '',
email: ''
},
SaveState: function () {
sessionStorage.userService = angular.toJson(service.model);
},
RestoreState: function () {
service.model = angular.fromJson(sessionStorage.userService);
}
}
$rootScope.$on("savestate", service.SaveState);
$rootScope.$on("restorestate", service.RestoreState);
return service;
}]);
userController example
function userCtrl($scope, userService) {
$scope.user = userService;
}
The view then uses binding like this
<h1>{{user.model.name}}</h1>
And in the app module, within the run function i handle the broadcasting of the saveState and restoreState
$rootScope.$on("$routeChangeStart", function (event, next, current) {
if (sessionStorage.restorestate == "true") {
$rootScope.$broadcast('restorestate'); //let everything know we need to restore state
sessionStorage.restorestate = false;
}
});
//let everthing know that we need to save state now.
window.onbeforeunload = function (event) {
$rootScope.$broadcast('savestate');
};
As i mentioned this took a while to come to this point. It is a very clean way of doing it, but it is a fair bit of engineering to do something that i would suspect is a very common issue when developing in Angular.
I would love to see easier, but as clean ways to handle keeping state across controllers, including when the user leaves and returns to the page.
I feel question deserves additional explanation.
As @fixxxer noted, the answer depends on the pandas version you are using in your project.
Which you can get with pd.__version__
command.
If you are for some reason like me (on debian jessie I use 0.14.1) using older version of pandas than 0.16.0, then you need to use:
df.keys().tolist()
because there is no df.columns
method implemented yet.
The advantage of this keys method is, that it works even in newer version of pandas, so it's more universal.
str1.toLowerCase().contains(str2.toLowerCase())
If you're running this on a cluster then println
won't print back to your context. You need to bring the RDD
data to your session. To do this you can force it to local array and then print it out:
linesWithSessionId.toArray().foreach(line => println(line))
$ git log --diff-filter=D --summary | grep "delete" | sort
Use the following statement: SHOW INDEX FROM your_table
And then check the result for the fields: row["Table"], row["Key_name"]
Make sure you write "Key_name" correctly
I usually take a slightly different track to achieve this:
$startTime = date("H:i",time() - 1800);
$endTime = date("H:i",time() + 1800);
Where 1800 seconds = 30 minutes.
in my case, I needed a
git add files
git commit -am 'what I changed'
git push
the 'a' on the commit was needed.
That is called the shebang line. As the Wikipedia entry explains:
In computing, a shebang (also called a hashbang, hashpling, pound bang, or crunchbang) refers to the characters "#!" when they are the first two characters in an interpreter directive as the first line of a text file. In a Unix-like operating system, the program loader takes the presence of these two characters as an indication that the file is a script, and tries to execute that script using the interpreter specified by the rest of the first line in the file.
See also the Unix FAQ entry.
Even on Windows, where the shebang line does not determine the interpreter to be run, you can pass options to the interpreter by specifying them on the shebang line. I find it useful to keep a generic shebang line in one-off scripts (such as the ones I write when answering questions on SO), so I can quickly test them on both Windows and ArchLinux.
The env utility allows you to invoke a command on the path:
The first remaining argument specifies the program name to invoke; it is searched for according to the
PATH
environment variable. Any remaining arguments are passed as arguments to that program.
The answer provided by polygenelubricants splits an array based on given size. I was looking for code that would split an array into a given number of parts. Here is the modification I did to the code:
public static <T>List<List<T>> chopIntoParts( final List<T> ls, final int iParts )
{
final List<List<T>> lsParts = new ArrayList<List<T>>();
final int iChunkSize = ls.size() / iParts;
int iLeftOver = ls.size() % iParts;
int iTake = iChunkSize;
for( int i = 0, iT = ls.size(); i < iT; i += iTake )
{
if( iLeftOver > 0 )
{
iLeftOver--;
iTake = iChunkSize + 1;
}
else
{
iTake = iChunkSize;
}
lsParts.add( new ArrayList<T>( ls.subList( i, Math.min( iT, i + iTake ) ) ) );
}
return lsParts;
}
Hope it helps someone.
You can also use ADO to do this: http://weblogs.asp.net/fmarguerie/archive/2003/10/01/29964.aspx
This should do it:
sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *
it will replace all occurrences of "deletethis" with "" (nothing) in all files (*
), editing them in place.
In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".
The third form is the way some versions of sed
like it. (e.g. Mac OS X)
man sed
for more information.
The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave
The following is adapted from a blog post answering this question that I posted while this question was still closed. Links are to (an HTML copy of) the ECMAScript 3 spec, still the baseline for JavaScript in today's commonly used web browsers.
First, a comment: this kind of expression is never going to show up in any (sane) production environment and is only of any use as an exercise in just how well the reader knows the dirty edges of JavaScript. The general principle that JavaScript operators implicitly convert between types is useful, as are some of the common conversions, but much of the detail in this case is not.
The expression ++[[]][+[]]+[+[]]
may initially look rather imposing and obscure, but is actually relatively easy break down into separate expressions. Below I’ve simply added parentheses for clarity; I can assure you they change nothing, but if you want to verify that then feel free to read up about the grouping operator. So, the expression can be more clearly written as
( ++[[]][+[]] ) + ( [+[]] )
Breaking this down, we can simplify by observing that +[]
evaluates to 0
. To satisfy yourself why this is true, check out the unary + operator and follow the slightly tortuous trail which ends up with ToPrimitive converting the empty array into an empty string, which is then finally converted to 0
by ToNumber. We can now substitute 0
for each instance of +[]
:
( ++[[]][0] ) + [0]
Simpler already. As for ++[[]][0]
, that’s a combination of the prefix increment operator (++
), an array literal defining an array with single element that is itself an empty array ([[]]
) and a property accessor ([0]
) called on the array defined by the array literal.
So, we can simplify [[]][0]
to just []
and we have ++[]
, right? In fact, this is not the case because evaluating ++[]
throws an error, which may initially seem confusing. However, a little thought about the nature of ++
makes this clear: it’s used to increment a variable (e.g. ++i
) or an object property (e.g. ++obj.count
). Not only does it evaluate to a value, it also stores that value somewhere. In the case of ++[]
, it has nowhere to put the new value (whatever it may be) because there is no reference to an object property or variable to update. In spec terms, this is covered by the internal PutValue operation, which is called by the prefix increment operator.
So then, what does ++[[]][0]
do? Well, by similar logic as +[]
, the inner array is converted to 0
and this value is incremented by 1
to give us a final value of 1
. The value of property 0
in the outer array is updated to 1
and the whole expression evaluates to 1
.
This leaves us with
1 + [0]
... which is a simple use of the addition operator. Both operands are first converted to primitives and if either primitive value is a string, string concatenation is performed, otherwise numeric addition is performed. [0]
converts to "0"
, so string concatenation is used, producing "10"
.
As a final aside, something that may not be immediately apparent is that overriding either one of the toString()
or valueOf()
methods of Array.prototype
will change the result of the expression, because both are checked and used if present when converting an object into a primitive value. For example, the following
Array.prototype.toString = function() {
return "foo";
};
++[[]][+[]]+[+[]]
... produces "NaNfoo"
. Why this happens is left as an exercise for the reader...
If you need to add multiple key=>value, then try this.
$data = array_merge($data, array("cat"=>"wagon","foo"=>"baar"));
You can use Scanner Class to find whether a given number could be read as Int or Float type.
import java.util.Scanner;
public class Test {
public static void main(String args[] ) throws Exception {
Scanner sc=new Scanner(System.in);
if(sc.hasNextInt())
System.out.println("This input is of type Integer");
else if(sc.hasNextFloat())
System.out.println("This input is of type Float");
else
System.out.println("This is something else");
}
}
You cannot directly use a SQL statement in a PL/SQL expression:
SQL> begin
2 if (select count(*) from dual) >= 1 then
3 null;
4 end if;
5 end;
6 /
if (select count(*) from dual) >= 1 then
*
ERROR at line 2:
ORA-06550: line 2, column 6:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:
...
...
You must use a variable instead:
SQL> set serveroutput on
SQL>
SQL> declare
2 v_count number;
3 begin
4 select count(*) into v_count from dual;
5
6 if v_count >= 1 then
7 dbms_output.put_line('Pass');
8 end if;
9 end;
10 /
Pass
PL/SQL procedure successfully completed.
Of course, you may be able to do the whole thing in SQL:
update my_table
set x = y
where (select count(*) from other_table) >= 1;
It's difficult to prove that something is not possible. Other than the simple test case above, you can look at the syntax diagram for the IF
statement; you won't see a SELECT
statement in any of the branches.
segmentation fault arrives when you access memory which is not declared by the program. You can do this through pointers i.e through memory addresses. Or this may also be due to stackoverflow for eg:
void rec_func() {int q = 5; rec_func();}
int main() {rec_func();}
This call will keep on consuming stack memory until it's completely filled and thus finally stackoverflow happens. Note: it might not be visible in some competitive questions as it leads to timeouterror first but for those in which timeout doesn't happens its a hard time figuring out sigsemv.
The solution for me was after touchend was to clone and replace the node... i hate doing this but even trying to repaint the element with offsetHeight wasn't working
let cloneNode = originNode.cloneNode( true );
originNode.parentNode.replaceChild( cloneNode, originNode );
@section
is for defining a content are override from a shared view. Basically, it is a way for you to adjust your shared view (similar to a Master Page in Web Forms).
You might find Scott Gu's write up on this very interesting.
Edit: Based on additional question clarification
The @RenderSection
syntax goes into the Shared View, such as:
<div id="sidebar">
@RenderSection("Sidebar", required: false)
</div>
This would then be placed in your view with @Section
syntax:
@section Sidebar{
<!-- Content Here -->
}
In MVC3+ you can either define the Layout file to be used for the view directly or you can have a default view for all views.
Common view settings can be set in _ViewStart.cshtml which defines the default layout view similar to this:
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
You can also set the Shared View to use directly in the file, such as index.cshtml directly as shown in this snippet.
@{
ViewBag.Title = "Corporate Homepage";
ViewBag.BodyID = "page-home";
Layout = "~/Views/Shared/_Layout2.cshtml";
}
There are a variety of ways you can adjust this setting with a few more mentioned in this SO answer.
I think df['word'].value_counts()
should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count
should be much slower than max
. Both take some time to avoid missing values. (Compare with size
.)
In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.
If you have content with height unknown but you know the height the of container. The following solution works extremely well.

One gotcha for newby's to display: inline-block; [span] and [p] have no html white space so that the span then doesn't take up any space. Also I've added in the CSS hack for display inline-block for IE. Hope this helps someone!
System.currentTimeMillis()
does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date
instance to a string before using it. You can use DateFormat
s to convert Date
s to String
s in any timezone:
DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());
It is easy to check for removable devices. However, there's no guarantee that it is a USB device:
var drives = DriveInfo.GetDrives()
.Where(drive => drive.IsReady && drive.DriveType == DriveType.Removable);
This will return a list of all removable devices that are currently accessible. More information:

enumeration (msdn documentation)The answer for conversion of char to int or long is simple casting.
For example:- if you would like to convert Char '0' into long.
Follow simple cast
Char ch='0';
String convertedChar= Character.toString(ch); //Convert Char to String.
Long finalLongValue=Long.parseLong(convertedChar);
Done!!

You can set a breakpoint, and then just open the debug console. So, the first thing you need to turn on your debug console:
After you've enabled, set a break-point to where you want it to:
After you're done setting the break-point:
Once that has been completed:
while [ -n $(passwd) ]; do
echo "Try again";
done;
Another option is to create a function and call that function everytime you need to select clob column.
create or replace function clob_to_char_func
(clob_column in CLOB,
for_how_many_bytes in NUMBER,
from_which_byte in NUMBER)
return VARCHAR2
is
begin
Return substrb(dbms_lob.substr(clob_column
,for_how_many_bytes
,from_which_byte)
,1
,for_how_many_bytes);
end;
and call that function as;
SELECT tocharvalue, clob_to_char_func(tocharvalue, 1, 9999)
FROM (SELECT clob_column AS tocharvalue FROM table_name);
try this
var value = iterate('tr.item span.value');
var quantity = iterate('tr.item span.quantity');
function iterate(selector)
{
var result = '';
if ($(selector))
{
$(selector).each(function ()
{
if (result == '')
{
result = $(this).html();
}
else
{
result = result + "," + $(this).html();
}
});
}
}
I wanted to make this post because I'm an undergrad CS student and more and more we use OpenDSA and other open source textbooks. It seems like from the top rated answer that the way height and depth is being taught has changed from one generation to the next, and I'm posting this so everyone is aware that this discrepancy now exists and hopefully won't cause bugs in any programs! Thanks.
From the OpenDSA Data Structures & Algos book:
If n1, n2,...,nk is a sequence of nodes in the tree such that ni is the parent of ni+1 for 1<=i<k, then this sequence is called a path from n1 to nk. The length of the path is k-1. If there is a path from node R to node M, then R is an ancestor of M, and M is a descendant of R. Thus, all nodes in the tree are descendants of the root of the tree, while the root is the ancestor of all nodes. The depth of a node M in the tree is the length of the path from the root of the tree to M. The height of a tree is one more than the depth of the deepest node in the tree. All nodes of depth d are at level d in the tree. The root is the only node at level 0, and its depth is 0.
Figure 7.2.1: A binary tree. Node A is the root. Nodes B and C are A's children. Nodes B and D together form a subtree. Node B has two children: Its left child is the empty tree and its right child is D. Nodes A, C, and E are ancestors of G. Nodes D, E, and F make up level 2 of the tree; node A is at level 0. The edges from A to C to E to G form a path of length 3. Nodes D, G, H, and I are leaves. Nodes A, B, C, E, and F are internal nodes. The depth of I is 3. The height of this tree is 4.
Below are the methods which have always worked for me
Set the display of the parent div to display: flex;
and the you can align the child elements inside the div using the justify-content: center;
(to align the items on main axis) and align-items: center;
(to align the items on cross axis).
If you have more than one child element and want to control the way they are arranged (column/rows), then you can also add flex-direction
property.
Working example:
.parent {_x000D_
align-items: center;_x000D_
border: 1px solid black;_x000D_
display: flex;_x000D_
justify-content: center;_x000D_
height: 250px;_x000D_
width: 250px;_x000D_
}_x000D_
_x000D_
.child {_x000D_
border: 1px solid black;_x000D_
height: 50px;_x000D_
width: 50px;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="child"></div>_x000D_
</div>
_x000D_
2. (older method) Using position, margin properties and fixed size
Working example:
.parent {_x000D_
border: 1px solid black;_x000D_
height: 250px;_x000D_
position: relative;_x000D_
width: 250px;_x000D_
}_x000D_
_x000D_
.child {_x000D_
border: 1px solid black;_x000D_
margin: auto;_x000D_
top: 0;_x000D_
bottom: 0;_x000D_
left: 0;_x000D_
right: 0;_x000D_
height: 50px;_x000D_
position: absolute;_x000D_
width: 50px;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="child"></div>_x000D_
</div>
_x000D_
Yacoby's answer inspires me to write an adaptor for encapsulating the functor boilerplate.
template< class T, bool (*comp)( T const &, T const & ) >
class set_funcomp {
struct ftor {
bool operator()( T const &l, T const &r )
{ return comp( l, r ); }
};
public:
typedef std::set< T, ftor > t;
};
// usage
bool my_comparison( foo const &l, foo const &r );
set_funcomp< foo, my_comparison >::t boo; // just the way you want it!
Wow, I think that was worth the trouble!
I smell homework, so probably an ArrayList won't be allowed (?)
Instead of looking for a way to "shift indexes", maybe just build a new array:
int[] b = new int[a.length +1];
Then
//edit: copy values of course, not indexes
Try this:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//***Change Here***
startActivity(intent);
finish();
System.exit(0);
For beginners: To create your .bash_profile
file in your home directory on MacOS, run:
nano ~/.bash_profile
Then you can paste in the following:
https://gist.github.com/mocon/0baf15e62163a07cb957888559d1b054
As you can see, it includes some example aliases and an environment variable at the bottom.
One you're done making your changes, follow the instructions at the bottom of the Nano editor window to WriteOut (Ctrl-O
) and Exit (Ctrl-X
). Then quit your Terminal and reopen it, and you will be able to use your newly defined aliases and environment variables.
UPDATE
Microsoft now provide this artifact in maven central. See @nirmal's answer for further details: https://stackoverflow.com/a/41149866/1570834
ORIGINAL ANSWER
The issue is that Maven can't find this artifact in any of the configured maven repositories.
Unfortunately Microsoft doesn't make this artifact available via any maven repository. You need to download the jar from the Microsoft website, and then manually install it into your local maven repository.
You can do this with the following maven command:
mvn install:install-file -Dfile=sqljdbc4.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.0 -Dpackaging=jar
Then next time you run maven on your POM it will find the artifact.
Slightly changed to David Murdoch's code for generic library

VanDyke VShell is the best Windows SSH Server I've ever worked with. It is kind of expensive though ($250). If you want a free solution, freeSSHd works okay. The CYGWIN solution is always an option, I've found, however, that it is a lot of work & overhead just to get SSH.
A solution, can be:
with open("file", "r") as fd:
lines = fd.read().splitlines()
You get the list of lines without "\r\n" or "\n".
Or, use the classic way:
with open("file", "r") as fd:
for line in fd:
line = line.strip()
You read the file, line by line and drop the spaces and newlines.
If you only want to drop the newlines:
with open("file", "r") as fd:
for line in fd:
line = line.replace("\r", "").replace("\n", "")
Et voilà.
Note: The behavior of Python 3 is a little different. To mimic this behavior, use io.open
.
See the documentation of io.open.
So, you can use:
with io.open("file", "r", newline=None) as fd:
for line in fd:
line = line.replace("\n", "")
When the newline parameter is None
: lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n'.
newline controls how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows:
On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newlines mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated.
If you're using chained syntax:
$(".class").each(function() {
// ...
});
...I don't think there's any (reasonable) way for the code within the each
function to know how many items there are. (Unreasonable ways would involve repeating the selector and using index
.)
But it's easy enough to make the collection available to the function that you're calling in each
. Here's one way to do that:
var collection = $(".class");
collection.each(function() {
// You can access `collection.length` here.
});
As a somewhat convoluted option, you could convert your jQuery object to an array and then use the array's forEach
. The arguments that get passed to forEach
's callback are the entry being visited (what jQuery gives you as this
and as the second argument), the index of that entry, and the array you called it on:
$(".class").get().forEach(function(entry, index, array) {
// Here, array.length is the total number of items
});
That assumes an at least vaguely modern JavaScript engine and/or a shim for Array#forEach
.
Or for that matter, give yourself a new tool:
// Loop through the jQuery set calling the callback:
// loop(callback, thisArg);
// Callback gets called with `this` set to `thisArg` unless `thisArg`
// is falsey, in which case `this` will be the element being visited.
// Arguments to callback are `element`, `index`, and `set`, where
// `element` is the element being visited, `index` is its index in the
// set, and `set` is the jQuery set `loop` was called on.
// Callback's return value is ignored unless it's `=== false`, in which case
// it stops the loop.
$.fn.loop = function(callback, thisArg) {
var me = this;
return this.each(function(index, element) {
return callback.call(thisArg || element, element, index, me);
});
};
Usage:
$(".class").loop(function(element, index, set) {
// Here, set.length is the length of the set
});
Unlike traditional RBDMs, mongoDB doesn't allow you to define any random field as the primary key, the _id field MUST exist for all standard documents.
For this reason, it doesn't make sense to create a separate uuid field.
In mongoose, the ObjectId type is used not to create a new uuid, rather it is mostly used to reference other documents.
Here is an example:
var mongoose = require('mongoose');
var Schema = mongoose.Schema,
ObjectId = Schema.ObjectId;
var Schema_Product = new Schema({
categoryId : ObjectId, // a product references a category _id with type ObjectId
title : String,
price : Number
});
As you can see, it wouldn't make much sense to populate categoryId with a ObjectId.
However, if you do want a nicely named uuid field, mongoose provides virtual properties that allow you to proxy (reference) a field.
Check it out:
var mongoose = require('mongoose');
var Schema = mongoose.Schema,
ObjectId = Schema.ObjectId;
var Schema_Category = new Schema({
title : String,
sortIndex : String
});
Schema_Category.virtual('categoryId').get(function() {
return this._id;
});
So now, whenever you call category.categoryId, mongoose just returns the _id instead.
You can also create a "set" method so that you can set virtual properties, check out this link for more info
this.$router.push({ query: Object.assign(this.$route.query, { new: 'param' }) })
Try this......pass in the number to be rounded off and it will round off to the nearest tenth.hope it helps....

You can do this by using asynchronous Javascript SDK provided by facebook
Have a look at the following code
FB Javascript SDK initialization
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'YOUR APP ID', status: true, cookie: true,
xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
Note: Remember to replace YOUR APP ID with your facebook AppId. If you don't have facebook AppId and you don't know how to create please check this
Add JQuery Library, I would preferred Google Library
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>
Add share dialog box (You can customize this dialog box by setting up parameters
<script type="text/javascript">
$(document).ready(function(){
$('#share_button').click(function(e){
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'This is the content of the "name" field.',
link: 'http://www.groupstudy.in/articlePost.php?id=A_111213073144',

The console.log
should be wrapped in a function , the "default" function for every class is its constructor
so it should be declared there.
import { Component } from '@angular/core';
console.log("Hello1");
@Component({
selector: 'hello-console',
})
export class App {
s: string = "Hello2";
constructor(){
console.log(s);

var mvar = $('.mbox').wrapAll(document.createElement('div')).closest('div').text();
console.log(mvar);

I don't know about all the lifecycle hooks, but as for destruction, ngOnDestroy
actually get called on Injectable when it's provider is destroyed (for example an Injectable supplied by a component).
From the docs :
Lifecycle hook that is called when a directive, pipe or service is destroyed.
Just in case anyone is interested in destruction check this question:
You can also use RedirectMatch directive to deny access to a folder.
To deny access to a folder, you can use the following RedirectMatch in htaccess :
RedirectMatch 403 ^/folder/?$
This will forbid an external access to /folder/ eg : http://example.com/folder/ will return a 403 forbidden error.
To deny access to everything inside the folder, You can use this :
RedirectMatch 403 ^/folder/.*$
This will block access to the entire folder eg : http://example.com/folder/anyURI will return a 403 error response to client.
I have an Xml File books.xml
<ParameterDBConfig>
<ID Definition="1" />
</ParameterDBConfig>
Program:
XmlDocument doc = new XmlDocument();
doc.Load("D:/siva/books.xml");
XmlNodeList elemList = doc.GetElementsByTagName("ID");
for (int i = 0; i < elemList.Count; i++)
{
string attrVal = elemList[i].Attributes["Definition"].Value;
}
Now, attrVal
has the value of ID
.
The set
statement doesn't treat spaces the way you expect; your variable is really named Pathname[space]
and is equal to [space]C:\Program Files
.
Remove the spaces from both sides of the =
sign, and put the value in double quotes:
set Pathname="C:\Program Files"
Also, if your command prompt is not open to C:\, then using cd
alone can't change drives.
Use
cd /d %Pathname%
or
pushd %Pathname%
instead.
I done this way:
$scope.printDiv = function (div) {
var docHead = document.head.outerHTML;
var printContents = document.getElementById(div).outerHTML;
var winAttr = "location=yes, statusbar=no, menubar=no, titlebar=no, toolbar=no,dependent=no, width=865, height=600, resizable=yes, screenX=200, screenY=200, personalbar=no, scrollbars=yes";
var newWin = window.open("", "_blank", winAttr);
var writeDoc = newWin.document;
writeDoc.open();
writeDoc.write('<!doctype html><html>' + docHead + '<body onLoad="window.print()">' + printContents + '</body></html>');
writeDoc.close();
newWin.focus();
}
I feel a bit weird writing this, but I can't be 100% sure that it's not true in some cases (it worked for me). If you had the following symptoms:
Then, try this:
I unplugged my phone and let it rest for ENTIRE DAY. My battery wore off a little. After this, I reconnected it and started debugging again. Everything worked fine this time! And I mean really REALLY fine, just as before.
Is it possible that this error might be due to some battery-related hardware stuff? It still feels weird thinking this way, but now I keep disconnecting my phone every now and then (and for the night) and the problem didn't return.
get_template_directory_uri();
This function will help you retrieve theme directory URI, and can be used with your images, your example below:
<img src="<?php echo get_template_directory_uri(); ?>/images/mindset.jpg" />
If the types of the parameters are all the same (varchar2
for example), you can have a package like this which will do the following:
CREATE OR REPLACE PACKAGE testuser.test_pkg IS
TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);
END test_pkg;
CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
BEGIN
FOR i IN p_parm.first .. p_parm.last
LOOP
dbms_output.put_line(p_parm(i));
END LOOP;
END;
END test_pkg;
Then, to call it you'd need to set up the array and pass it:
DECLARE
l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
l_array(0) := 'hello';
l_array(1) := 'there';
testuser.test_pkg.your_proc(l_array);
END;

I must use templates for a internal APP and it works for me:
'DIRS': [os.path.join(BASE_DIR + '/THE_APP_NAME', 'templates')],
Either !=
or ne
will work, but you need to get the accessor syntax and nested quotes sorted out.
<c:if test="${content.contentType.name ne 'MCE'}">
<%-- snip --%>
</c:if>
I made a small tool providing similar functionality, without using xclip or xsel. stdout
is copied to a clipboard and can be pasted again in the terminal. See:
https://sourceforge.net/projects/commandlinecopypaste/
Note, that this tool does not need an X-session. The clipboard can just be used within the terminal and has not to be pasted by Ctrl+V or middle-mouse-click into other X-windows.
The List<>
class does guarantee ordering - things will be retained in the list in the order you add them, including duplicates, unless you explicitly sort the list.
According to MSDN:
...List "Represents a strongly typed list of objects that can be accessed by index."
The index values must remain reliable for this to be accurate. Therefore the order is guaranteed.
You might be getting odd results from your code if you're moving the item later in the list, as your Remove()
will move all of the other items down one place before the call to Insert()
.
Can you boil your code down to something small enough to post?
Note that, in addition to number of predictive variables, the Adjusted R-squared formula above also adjusts for sample size. A small sample will give a deceptively large R-squared.
Ping Yin & Xitao Fan, J. of Experimental Education 69(2): 203-224, "Estimating R-squared shrinkage in multiple regression", compares different methods for adjusting r-squared and concludes that the commonly-used ones quoted above are not good. They recommend the Olkin & Pratt formula.
However, I've seen some indication that population size has a much larger effect than any of these formulas indicate. I am not convinced that any of these formulas are good enough to allow you to compare regressions done with very different sample sizes (e.g., 2,000 vs. 200,000 samples; the standard formulas would make almost no sample-size-based adjustment). I would do some cross-validation to check the r-squared on each sample.
Python 3.0 doesn't have sys.maxint any more since Python 3's ints are of arbitrary length. Instead of sys.maxint it has sys.maxsize; the maximum size of a positive sized size_t aka Py_ssize_t.
Programming habits could help too; e.g. add static
to functions that are not accessed outside a specific file; use shorter names for symbols (can help a bit, likely not too much); use const char x[]
where possible; ... this paper, though it talks about dynamic shared objects, can contain suggestions that, if followed, can help to make your final binary output size smaller (if your target is ELF).
in run time, you can use following code
btn.setBackgroundDrawable(null);
When I create a root class, whose methods I defined using the arrow functions. When inheriting and overwriting the original function I noticed the same issue.
class C {
x = () => 1;
};
class CC extends C {
x = (foo) => super.x() + foo;
};
let add = new CC;
console.log(add.x(4));
this is solved by defining the method of the parent class without arrow functions
class C {
x() {
return 1;
};
};
class CC extends C {
x = foo => super.x() + foo;
};
let add = new CC;
console.log(add.x(4));
await Promise.all([someCall(), anotherCall()]); as already mention will act as a thread fence (very common in parallel code as CUDA), hence it will allow all the promises in it to run without blocking each other, but will prevent the execution to continue until ALL are resolved.
another approach that is worth to share is the Node.js async that will also allow you to easily control the amount of concurrency that is usually desirable if the task is directly linked to the use of limited resources as API call, I/O operations, etc.
// create a queue object with concurrency 2
var q = async.queue(function(task, callback) {
console.log('Hello ' + task.name);
callback();
}, 2);
// assign a callback
q.drain = function() {
console.log('All items have been processed');
};
// add some items to the queue
q.push({name: 'foo'}, function(err) {
console.log('Finished processing foo');
});
q.push({name: 'bar'}, function (err) {
console.log('Finished processing bar');
});
// add some items to the queue (batch-wise)
q.push([{name: 'baz'},{name: 'bay'},{name: 'bax'}], function(err) {
console.log('Finished processing item');
});
// add some items to the front of the queue
q.unshift({name: 'bar'}, function (err) {
console.log('Finished processing bar');
});

In Preferences, select Python Interpreter
Under Python Interpreter, change from "Default" to "Use the following Python interpreter"
The path there should be the default Python executable. Find your Python 2.7 executable and use that.
I know it is an old thread, but recently I needed the same and found a neat way:
SELECT c.name FROM pragma_table_info('your_table_name') c;
I can confirm that I am having the same issue. I am also using eclipse classic with CDT. The funny thing is that it only started happening earlier this evening. Before then, I was always prompted for the workspace. Checking "Prompt for workspace on startup" has no effect. I am not launching eclipse using a startup script, so the -data flag is not set on launch. I have removed the line "osgi.instance.area.default" from the configuration/config.ini, but that had no effect.
A few strange quirks that are incidental to this problem: If I delete the "workspace" workspace it creates it again upon launch. However, when I switch to one of my "real" workspaces I notice that the "workspace" workspace is not listed as an option to be switched to.
As would be expected, reinstalling eclipse resolves the issue. But it would be nicer to find a way to fix the problem without resorting to that.
A Meteor app does not, by default, add any X-Powered-By headers to HTTP responses, as you might find in various PHP apps. The headers look like:
$ curl -I https://atmosphere.meteor.com HTTP/1.1 200 OK content-type: text/html; charset=utf-8 date: Tue, 31 Dec 2013 23:12:25 GMT connection: keep-alive
However, this doesn't mask that Meteor was used. Viewing the source of a Meteor app will look very distinctive.
<script type="text/javascript"> __meteor_runtime_config__ = {"meteorRelease":"0.6.3.1","ROOT_URL":"http://atmosphere.meteor.com","serverId":"62a4cf6a-3b28-f7b1-418f-3ddf038f84af","DDP_DEFAULT_CONNECTION_URL":"ddp+sockjs://ddp--****-atmosphere.meteor.com/sockjs"}; </script>
If you're trying to avoid people being able to tell you are using Meteor even by viewing source, I don't think that's possible.
I'm on react native 0.55.4, basically i had to bundle manually:
react-native bundle --dev false --platform android --entry-file index.js --bundle-
output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-
dest ./android/app/build/intermediates/res/merged/debug
Then connect your device via usb, enable usb debugging. Verify the connected device with adb devices
.
Lastly run react-native run-android
which will install the debug apk on your phone and you can run it fine with the dev server
Note:
index.js
gradlew assembleRelease
only generates the release-unsigned apks which cannot be installedThis is similar to https://superuser.com/questions/477628/export-all-regular-expression-matches-in-textpad-or-notepad-as-a-list.
I hope you are trying to extract :
"Performance"
"Maintenance"
"System Stability"
Here is the way - Step 1/3: Open Search->Find->Replace Tab , select Regular Expression Radio button. Enter in Find what : (\"[a-zA-Z0-9\s]+\") and in Replace with : \n\1 and click Replace All buttton.
Step 2/3: After first step your keywords will be in next lines.(as shown in next image). Now go to Mark tab and enter the same regex expression in Find what: Field. Put check mark on Bookmark Line. Then Click Mark All.
Step 3/3 : Goto Search -> Bookmarks -> Remove unmarked lines.
Why not just use a step parameter of range function as well to get:
l = range(0, 1000, 10)
For comparison, on my machine:
H:\>python -m timeit -s "l = range(1000)" "l1 = [x for x in l if x % 10 == 0]"
10000 loops, best of 3: 90.8 usec per loop
H:\>python -m timeit -s "l = range(1000)" "l1 = l[0::10]"
1000000 loops, best of 3: 0.861 usec per loop
H:\>python -m timeit -s "l = range(0, 1000, 10)"
100000000 loops, best of 3: 0.0172 usec per loop

Next, you have to create the .pfx file that you will use to sign your deployments. Open a Command Prompt window, and type the following command:
PVK2PFX –pvk yourprivatekeyfile.pvk –spc yourcertfile.cer –pfx yourpfxfile.pfx –po yourpfxpassword
where:
- pvk - yourprivatekeyfile.pvk is the private key file that you created in step 4.
- spc - yourcertfile.cer is the certificate file you created in step 4.
- pfx - yourpfxfile.pfx is the name of the .pfx file that will be creating.
- po - yourpfxpassword is the password that you want to assign to the .pfx file. You will be prompted for this password when you add the .pfx file to a project in Visual Studio for the first time.
(Optionally (and not for the OP, but for future readers), you can create the .cer and .pvk file from scratch) (you would do this BEFORE the above). Note the mm/dd/yyyy are placeholders for start and end dates. see msdn article for full documentation.
makecert -sv yourprivatekeyfile.pvk -n "CN=My Certificate Name" yourcertfile.cer -b mm/dd/yyyy -e mm/dd/yyyy -r
Have a look:
Syntax (Via Composer):
composer create-project laravel/laravel {directory} 4.2 --prefer-dist
Example:
composer create-project laravel/laravel my_laravel_dir 4.2
Where 4.2 is your version of laravel.
Note: It will take the latest version of Laravel automatically If you will not provide any version.
em.persist(abc);
em.refresh(abc);
return abc;
You could just use the bound ng-model
(answers[item.questID]
) value itself in your ng-change method to detect if it has been checked or not.
Example:-
<input type="checkbox" ng-model="answers[item.questID]"
ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->
and
$scope.stateChanged = function (qId) {
if($scope.answers[qId]){ //If it is checked
alert('test');
}
}
And for negatives values:
Public Function IsBetween(Of T)(item As T, pStart As T, pEnd As T) As Boolean ' https://msdn.microsoft.com/fr-fr/library/bb384936.aspx
Dim Deb As T = pStart
Dim Fin As T = pEnd
If (Comparer(Of T).Default.Compare(pStart, pEnd) > 0) Then Deb = pEnd : Fin = pStart
Return Comparer(Of T).Default.Compare(item, Deb) >= 0 AndAlso Comparer(Of T).Default.Compare(item, Fin) <= 0
End Function
Use empty() and/or is_null()
http://www.php.net/empty http://www.php.net/is_null
Empty alone will achieve your current usage, is_null would just make more control possible if you wanted to distinguish between a field that is null and a field that is empty.
var text = "" &<>";
text = text.replaceHtmlEntites();
String.prototype.replaceHtmlEntites = function() {
var s = this;
var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
var translate = {"nbsp": " ","amp" : "&","quot": "\"","lt" : "<","gt" : ">"};
return ( s.replace(translate_re, function(match, entity) {
return translate[entity];
}) );
};
try this.....this worked for me

In principle, you can style it using option[selected] as selector, but that doesn't work in many browsers. Also, that only allows you to style the selected option, not the option that has hover focus.
Tested to work in Chrome 9 and Firefox 3.6, doesn't work in Internet Explorer 8.
Actually, guys, there is a way. I struggled mightily to figure this out for [LINK REMOVED] (try it on an iPhone or iPad).
Basically, Safari on touchscreen devices is stingy when it comes to focus()
ing textboxes. Even some desktop browsers do better if you do click().focus()
. But the designers of Safari on touchscreen devices realized it's annoying to users when the keyboard keeps coming up, so they made the focus appear only on the following conditions:
1) The user clicked somewhere and focus()
was called while executing the click event. If you are doing an AJAX call, then you must do it synchronously, such as with the deprecated (but still available) $.ajax({async:false})
option in jQuery.
2) Furthermore -- and this one kept me busy for a while -- focus()
still doesn't seem to work if some other textbox is focused at the time. I had a "Go" button which did the AJAX, so I tried blurring the textbox on the touchstart
event of the Go button, but that just made the keyboard disappear and moved the viewport before I had a chance to complete the click on the Go button. Finally I tried blurring the textbox on the touchend
event of the Go button, and this worked like a charm!
When you put #1 and #2 together, you get a magical result that will set your login forms apart from all the crappy web login forms, by placing the focus in your password fields, and make them feel more native. Enjoy! :)
Use System.in, it is an InputStream which just serves this purpose
MizardX's answer gives a good collection of multiple approaches.
This is what I came up with while thinking aloud:
mylist = [x for i,x in enumerate(mylist) if x not in mylist[i+1:]]
I just tried with this code, and it worked for me: <link rel="icon" type="image/jpg" href="C:\Users\nrm05\Pictures\logo.jpg" />
Be sure to type type="image/jpg"
for jpg files, and type="image/png"
for PNG files. If you haven't downloaded the image, but you know the image URL, then you can type it in like this: href="image_url"
Hope this answered your question :-)
setFixedLengthStreamingMode(int) with contentLength parameters could set the fixed length of a HTTP request body.
Just do:

Regarding the issue with 'size', size is not a function on a dataframe, it is rather a property. So instead of using size(), plain size should work
Apart from that, a method like this should work
def doCalculation(df):
groupCount = df.size
groupSum = df['my_labels'].notnull().sum()
return groupCount / groupSum
dataFrame.groupby('my_labels').apply(doCalculation)
There is an extended stored procedure sp_spaceused
that gets this information out. It's fairly convoluted to do it from the data dictionary, but This link fans out to a script that does it. This stackoverflow question has some fan-out to information on the underlying data structures that you can use to construct estimates of table and index sizes for capcity planning.
This code works for me:
Sub test()
Dim myRange As Range
Dim NumRows As Integer
Set myRange = Range("A:A")
NumRows = Application.WorksheetFunction.CountA(myRange)
MsgBox NumRows
End Sub
Note this isn't at heart a question about JComboBox, but about any collection that can include multiple types of objects. The same could be said for "How do I get a String out of a List?" or "How do I get a String
out of an Object[]
?"
I think the previous answer is the best way to do it here is another simple way. just to print the sorted results.
String path="/tmp";
String[] dirListing = null;
File dir = new File(path);
dirListing = dir.list();
Arrays.sort(dirListing);
System.out.println(Arrays.deepToString(dirListing));

These days, many site owners are using CDN services which pulls data from CDN server. If that's your case then you are left with two options:
Create a subdomain and edit DNS by Adding a CNAME record
Don't create a subdomain but only create a CNAME record pointing back to your temporary DNS URL.
This solution only implies to pulling code from CDN which will show that it's fetching data from cdn.sitename.com but practically its pulling from your CDN host.
on Ubuntu using PHP 5.59 :
got to `:
/etc/php5/cli/conf.d
and find your xdebug.ini in that dir, in my case is 20-xdebug.ini
and add this line `
xdebug.max_nesting_level = 200
or this
xdebug.max_nesting_level = -1
set it to -1 and you dont have to worry change the value of the nesting level.

No. NodeJS is not available as an Apache module in the way mod-perl and mod-php are, so it's not possible to run node "on top of" Apache. As hexist pointed out, it's possible to run node as a separate process and arrange communication between the two, but this is quite different to the LAMP stack you're already using.
As a replacement for Apache, node offers performance advantages if you have many simultaneous connections. There's also a huge ecosystem of modules for almost anything you can think of.
From your question, it's not clear if you need to dynamically generate pages on every request, or just generate new content periodically for caching and serving. If its the latter, you could use separate node task to generate content to a directory that Apache would serve, but again, that's quite different to PHP or Perl.
Node isn't the best way to serve static content. Nginx and Varnish are more effective at that. They can serve static content while Node handles the dynamic data.
If you're considering using node for a web application at all, Express should be high on your list. You could implement a web application purely in Node, but Express (and similar frameworks like Flatiron, Derby and Meteor) are designed to take a lot of the pain and tedium away. Although the Express documentation can seem a bit sparse at first, check out the screen casts which are still available here: http://expressjs.com/2x/screencasts.html They'll give you a good sense of what express offers and why it is useful. The github repository for ExpressJS also contains many good examples for everything from authentication to organizing your app.

I discovered, that it works when sending with content type
"application/json"
in combination with server-side
app.use(bodyParser.json());
Now I can send via
var data = {name:"John"}
var xmlHttp = new XMLHttpRequest();
xmlHttp.open("POST", theUrl, false); // false for synchronous request
xmlHttp.setRequestHeader("Content-type", "application/json");
xmlHttp.send(data);
and the result is available in request.body.name
on the server.
In my case Malwarebytes was holding a handle on my program's executable:
Using Process Explorer to close the handle, or just disabling antivirus for a bit work just fine.
This issue may also occur if you have multiple versions of the same support library android-support-v4.jar
. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.
I have a files only website. Added MVC 5 to webforms application (targeting net45). I had to modify the packages.config
package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45"
to
package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45" developmentDependency="true"
in order for it to startup on local box in debug mode (previously had the top described error). Running VS 2017 on Windows 7...opened through File > Open > Web Site > File (chose root directory outside of IIS).
Tiers are nothing but the separation of concerns and in general the presentation layer (the forms or pages that is visible to the user) is separated from the data tier (the class or file interact with the database). This separation is done in order to improve the maintainability, scalability, re-usability, flexibility and performance as well.
A good explanations with demo code of 3-tier and 4-tier architecture can be read at http://www.dotnetfunda.com/articles/article71.aspx
I really need to instantiate a T in Foo using a parameter-less constructor
Simple answer is "you cant do that" java uses type erasure to implment generics which would prevent you from doing this.
How can one work around Java's limitation?
One way (there could be others) is to pass the object that you would pass the instance of T to the constructor of Foo<T>
. Or you could have a method setBar(T theInstanceofT);
to get your T instead of instantiating in the class it self.
As of July 2018 and the release of RxJS 6
, the new way to get an Observable from a value is to import the of
operator like so:
import { of } from 'rxjs';
and then create the observable from the value, like so:
of(someValue);
Note, that you used to have to do Observable.of(someValue)
like in the currently accepted answer. There is a good article on the other RxJS 6 changes here.

Datatables supports HTML5 data-* attributes for this functionality.
It supports multiple columns in the sort order (it's 0-based)
<table data-order="[[ 1, 'desc' ], [2, 'asc' ]]">
<thead>
<tr>
<td>First</td>
<td>Another column</td>
<td>A third</td>
</tr>
</thead>
<tbody>
<tr>
<td>z</td>
<td>1</td>
<td>$%^&*</td>
</tr>
<tr>
<td>y</td>
<td>2</td>
<td>*$%^&</td>
</tr>
</tbody>
</table>
Now my jQuery is simply $('table').DataTables();
and I get my second and third columns sorted in desc / asc order.
Here's some other nice attributes for the <table>
that I find myself reusing:
data-page-length="-1"
will set the page length to All (pass 25 for page length 25)...
data-fixed-header="true"

Use extension methods. Replace NameOfContext with the name of your object context.
public static class Extensions{
public static IQueryable<Company> CompleteCompanies(this NameOfContext context){
return context.Companies
.Include("Employee.Employee_Car")
.Include("Employee.Employee_Country") ;
}
public static Company CompanyById(this NameOfContext context, int companyID){
return context.Companies
.Include("Employee.Employee_Car")
.Include("Employee.Employee_Country")
.FirstOrDefault(c => c.Id == companyID) ;
}
}
Then your code becomes
Company company =
context.CompleteCompanies().FirstOrDefault(c => c.Id == companyID);
//or if you want even more
Company company =
context.CompanyById(companyID);

You can change your GitHub profile password and revoke all "Personal access tokens" in "Settings -> Developer settings" of your profile. Also you can optionally wipe all your SSH/PGP keys and OAuth/GitHub apps to be sure that access to the repository is completely blocked. Thus, all the credential managers, on any system will fail at authorisation and prompt you to enter the new credentials.
I couldn't find solution for other browsers. When I posted this question, IE was on the higher priority and gladly I found one for it. If you have a solution for other browsers (firefox, safari, opera) please do share here. Thanks.
VBSCRIPT is much more convenient than creating an ActiveX on VB6 or C#/VB.NET:
<script language='VBScript'>
Sub Print()
OLECMDID_PRINT = 6
OLECMDEXECOPT_DONTPROMPTUSER = 2
OLECMDEXECOPT_PROMPTUSER = 1
call WB.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER,1)
End Sub
document.write "<object ID='WB' WIDTH=0 HEIGHT=0 CLASSID='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'></object>"
</script>
Now, calling:
<a href="javascript:window.print();">Print</a>
will send print without popup print window.
If it's published, you can't delete it (without risking being tarred and feathered, that is). The 'Git way' is to do:
The sane thing. Just admit you screwed up, and use a different name. Others have already seen one tag-name, and if you keep the same name, you may be in the situation that two people both have "version X", but they actually have different "X"'s. So just call it "X.1" and be done with it.
Alternatively,
The insane thing. You really want to call the new version "X" too, even though others have already seen the old one. So just use git-tag -f again, as if you hadn't already published the old one.
It's so insane because:
Git does not (and it should not) change tags behind users back. So if somebody already got the old tag, doing a git-pull on your tree shouldn't just make them overwrite the old one.
If somebody got a release tag from you, you cannot just change the tag for them by updating your own one. This is a big security issue, in that people MUST be able to trust their tag-names. If you really want to do the insane thing, you need to just fess up to it, and tell people that you messed up.

location.reload();
You can use the reload
function in your if
condition for success and the page will reload after the condition is successful.
You don't have the access permission, maybe because you are not the owner.
Fix by changing the owner to yourself:
sudo chown -R your_login_name /path/to/folder
If you want the MIME type for a file, you can use the following code:
- (NSString *)mimeTypeForPath:(NSString *)path
{
// get a mime type for an extension using MobileCoreServices.framework
CFStringRef extension = (__bridge CFStringRef)[path pathExtension];
CFStringRef UTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, extension, NULL);
assert(UTI != NULL);
NSString *mimetype = CFBridgingRelease(UTTypeCopyPreferredTagWithClass(UTI, kUTTagClassMIMEType));
assert(mimetype != NULL);
CFRelease(UTI);
return mimetype;
}
In the case of a ZIP file, this will return application/zip
.
def prev_month(date=datetime.datetime.today()):
if date.month == 1:
return date.replace(month=12,year=date.year-1)
else:
try:
return date.replace(month=date.month-1)
except ValueError:
return prev_month(date=date.replace(day=date.day-1))
The main difference when working on arrays is that array_key_exists
returns true
when the value is null
, while isset
will return false
when the array value is set to null
.
See isset on the PHP documentation site.
It is considered bad practice to invoke the actual generator (e.g. via make
) if using CMake. It is highly recommended to do it like this:
Configure phase:
cmake -Hfoo -B_builds/foo/debug -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=/usr
Build and Install phases
cmake --build _builds/foo/debug --config Debug --target install
When following this approach, the generator can be easily switched (e.g. -GNinja
for Ninja) without having to remember any generator-specific commands.
npm install -d --save
worked for me. -d
flag command force npm to install your dependencies and --save
will save the all updated dependencies in your package.json
Try using
Dir.glob(".")
To see what's in the directory (and therefore what directory it's looking at).
You are trying to access the class as opposed to the object. That statement can be confusing to beginners, but you are effectively trying to open your house door by picking up the door on your house plans.
If you actually wanted to access the form components directly from a class (which you don't) you would use the variable that instantiates your form.
Depending on which way you want to go you'd be better of either sending the text of a control or whatever to a method in your classes eg
public void DoSomethingWithText(string formText)
{
// do something text in here
}
or exposing properties on your form class and setting the form text in there - eg
string SomeProperty
{
get
{
return textBox1.Text;
}
set
{
textBox1.Text = value;
}
}
You can use a Union.
This will return the results of the queries in separate rows.
First you must make sure that both queries return identical columns.
Then you can do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl
UNION
SELECT tableA.Id, tableA.Name, '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM
[tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name
As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.
SO
You can use a Join
If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...
You could do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
INNER JOIN
(SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans
FROM [tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id
GROUP BY tableA.Id, tableA.Name) AS query2
ON query2.Id = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl
readLine()
returns pointer to local variable, which causes undefined behaviour.
To get around you can:
readLine()
line
using malloc()
- in this case line
will be persistentDoing this fixed my issue
<script type="text/javascript">
function SubmitFrm(){
var Searchtxt = document.getElementById("txtSearch").value;
window.location = "http://www.mysite.com/search/?Query=" + Searchtxt;
}
</script>
I changed .value();
to .value;
taking out the ()
I did not change anything in my text field or submit button
<input name="txtSearch" type="text" id="txtSearch" class="field" />
<input type="submit" name="btnSearch" value="" id="btnSearch" class="btn" onclick="javascript:SubmitFrm()" />
Works like a charm.
