In my case I had in one report many different datasets to DB and Analysis Services Cube. Looks like that datasets blocked each other and generated such error. For me helped option "Use single transaction when processing the queries" in the CUBE datasource properties
I always remove the .gradle folder from %USERS% folder and start the studio again. When starting the IDE it downloads gradle again with all the dependencies again. Its work PERFECT.
You could try using the pure-python pymysql
:
sudo easy_install pymysql
(Or use pip
if you have it installed.) Then, add this before you import MySQLdb
in your code:
try:
import pymysql
pymysql.install_as_MySQLdb()
except ImportError:
pass
That's it. The 'else' block of a try-except clause exists for code that runs when (and only when) the tried operation succeeds. It can be used, and it can be abused.
try:
fp= open("configuration_file", "rb")
except EnvironmentError:
confdata= '' # it's ok if the file can't be opened
else:
confdata= fp.read()
fp.close()
# your code continues here
# working with (possibly empty) confdata
Personally, I like it and use it when appropriate. It semantically groups statements.
defaultMember
already is an alias - it doesn't need to be the name of the exported function/thing. Just do
import alias from 'my-module';
Alternatively you can do
import {default as alias} from 'my-module';
but that's rather esoteric.
System.IO.File.Create(@"C:\Temp.txt");
As others have pointed out, you should dispose of this object or wrap it in an empty using statement.
using (System.IO.File.Create(@"C:\Temp.txt"));
I created a generic solution out of the existing answers which can be reused for any table:
CREATE OR REPLACE FUNCTION create_if_not_exists (table_name text, create_stmt text)
RETURNS text AS
$_$
BEGIN
IF EXISTS (
SELECT *
FROM pg_catalog.pg_tables
WHERE tablename = table_name
) THEN
RETURN 'TABLE ' || '''' || table_name || '''' || ' ALREADY EXISTS';
ELSE
EXECUTE create_stmt;
RETURN 'CREATED';
END IF;
END;
$_$ LANGUAGE plpgsql;
Usage:
select create_if_not_exists('my_table', 'CREATE TABLE my_table (id integer NOT NULL);');
It could be simplified further to take just one parameter if one would extract the table name out of the query parameter. Also I left out the schemas.
Use Concat
or Union
extension methods. You have to make sure that you have this direction using System.Linq;
in order to use LINQ extensions methods.
Use the AddRange
method.
You don't need that much effort, here's a basic example.

You can play around with HTML

Definitely use a service to share data between controllers, here is a working example. $broadcast is not the way to go, you should avoid using the eventing system when there is a more appropriate way. Use a 'service', 'value' or 'constant' (for global constants).
http://plnkr.co/edit/ETWU7d0O8Kaz6qpFP5Hp
Here is an example with an input so you can see the data mirror on the page: http://plnkr.co/edit/DbBp60AgfbmGpgvwtnpU
var testModule = angular.module('testmodule', []);
testModule
.controller('QuestionsStatusController1',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
}]);
testModule
.controller('QuestionsStatusController2',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
}]);
testModule
.service('myservice', function() {
this.xxx = "yyy";
});
strsplit
to parse your input and, as Greg mentioned, assign
to assign the variables.
original_string <- c("x=123", "y=456")
pairs <- strsplit(original_string, "=")
lapply(pairs, function(x) assign(x[1], as.numeric(x[2]), envir = globalenv()))
ls()
A possible solution:
string filename = "C:\\MyDirectory\\MyFile.bat";
// Remove directory if present.
// Do this before extension removal incase directory has a period character.
const size_t last_slash_idx = filename.find_last_of("\\/");
if (std::string::npos != last_slash_idx)
{
filename.erase(0, last_slash_idx + 1);
}
// Remove extension if present.
const size_t period_idx = filename.rfind('.');
if (std::string::npos != period_idx)
{
filename.erase(period_idx);
}
I would create a comparator for the person class that can be parametrized with a certain sorting behaviour. Here I can set the sorting order but it can be modified to allow sorting for other person attributes as well.
public class PersonComparator implements Comparator<Person> {
public enum SortOrder {ASCENDING, DESCENDING}
private SortOrder sortOrder;
public PersonComparator(SortOrder sortOrder) {
this.sortOrder = sortOrder;
}
@Override
public int compare(Person person1, Person person2) {
Integer age1 = person1.getAge();
Integer age2 = person2.getAge();
int compare = Math.signum(age1.compareTo(age2));
if (sortOrder == ASCENDING) {
return compare;
} else {
return compare * (-1);
}
}
}
(hope it compiles now, I have no IDE or JDK at hand, coded 'blind')
Edit
Thanks to Thomas, edited the code. I wouldn't say that the usage of Math.signum is good, performant, effective, but I'd like to keep it as a reminder, that the compareTo method can return any integer and multiplying by (-1) will fail if the implementation returns Integer.MIN_INTEGER... And I removed the setter because it's cheap enough to construct a new PersonComparator just when it's needed.
But I keep the boxing because it shows that I rely on an existing Comparable implementation. Could have done something like Comparable<Integer> age1 = new Integer(person1.getAge());
but that looked too ugly. The idea was to show a pattern which could easily be adapted to other Person attributes, like name, birthday as Date and so on.
You can start with a blank tuple with something like t = ()
. You can add with +
, but you have to add another tuple. If you want to add a single element, make it a singleton: t = t + (element,)
. You can add a tuple of multiple elements with or without that trailing comma.
>>> t = ()
>>> t = t + (1,)
>>> t
(1,)
>>> t = t + (2,)
>>> t
(1, 2)
>>> t = t + (3, 4, 5)
>>> t
(1, 2, 3, 4, 5)
>>> t = t + (6, 7, 8,)
>>> t
(1, 2, 3, 4, 5, 6, 7, 8)
If you're using Java 8, you can use Lambda expressions to match.
import java.util.Optional;
import java.util.function.Predicate;
import org.hamcrest.BaseMatcher;
import org.hamcrest.Description;
public class LambdaMatcher<T> extends BaseMatcher<T>
{
private final Predicate<T> matcher;
private final Optional<String> description;
public LambdaMatcher(Predicate<T> matcher)
{
this(matcher, null);
}
public LambdaMatcher(Predicate<T> matcher, String description)
{
this.matcher = matcher;
this.description = Optional.ofNullable(description);
}
@SuppressWarnings("unchecked")
@Override
public boolean matches(Object argument)
{
return matcher.test((T) argument);
}
@Override
public void describeTo(Description description)
{
this.description.ifPresent(description::appendText);
}
}
Example call
@Test
public void canFindEmployee()
{
Employee employee = new Employee("John");
company.addEmployee(employee);
verify(mockedDal).registerEmployee(argThat(new LambdaMatcher<>(e -> e.getName()
.equals(employee.getName()))));
}

Using an absolute or relative string as the filename.
name_of_file = input("What is the name of the file: ")
completeName = '/home/user/Documents'+ name_of_file + ".txt"
file1 = open(completeName , "w")
toFile = input("Write what you want into the field")
file1.write(toFile)
file1.close()
The FOR-LOOP generally works, but there are some issues. The FOR doesn't accept empty lines and lines with more than ~8190 are problematic. The expansion works only reliable, if the delayed expansion is disabled.
Detection of CR/LF versus single LF seems also a little bit complicated.
Also NUL characters are problematic, as a FOR-Loop immediatly cancels the reading.
Direct binary reading seems therefore nearly impossible.
The problem with empty lines can be solved with a trick. Prefix each line with a line number, using the findstr command, and after reading, remove the prefix.
@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ t.txt"`) do (
set "var=%%a"
SETLOCAL EnableDelayedExpansion
set "var=!var:*:=!"
echo(!var!
ENDLOCAL
)
Toggling between enable and disabled delayed expansion is neccessary for the safe working with strings, like !
or ^^^xy!z
.
That's because the line set "var=%%a"
is only safe with DisabledDelayedExpansion, else exclamation marks are removed and the carets are used as (secondary) escape characters and they are removed too.
But using the variable var
is only safe with EnabledDelayedExpansion, as even a call %%var%%
will fail with content like "&"&
.
EDIT: Added set/p variant
There is a second way of reading a file with set /p
, the only disadvantages are that it is limited to ~1024 characters per line and it removes control characters at the line end.
But the advantage is, you didn't need the delayed toggling and it's easier to store values in variables
@echo off
setlocal EnableDelayedExpansion
set "file=%~1"
for /f "delims=" %%n in ('find /c /v "" %file%') do set "len=%%n"
set "len=!len:*: =!"
<%file% (
for /l %%l in (1 1 !len!) do (
set "line="
set /p "line="
echo(!line!
)
)
For reading it "binary" into a hex-representation
You could look at SO: converting a binary file to HEX representation using batch file
char variable = 'x'; // the variable is a char whose value is lowercase x
printf("<%c>", variable); // print it with angle brackets around the character
One can use a plain ImageView in his xml and make it clickable (android:clickable="true")? You only have to use as src an image that has been shaped like a button i.e round corners.
I guess you're searching for this custom function. It takes a data-toggle attribute and creates dynamically the necessary div to place the remote content. Just place the data-toggle="ajaxModal" on any link you want to load via AJAX.
The JS part:
$('[data-toggle="ajaxModal"]').on('click',
function(e) {
$('#ajaxModal').remove();
e.preventDefault();
var $this = $(this)
, $remote = $this.data('remote') || $this.attr('href')
, $modal = $('<div class="modal" id="ajaxModal"><div class="modal-body"></div></div>');
$('body').append($modal);
$modal.modal({backdrop: 'static', keyboard: false});
$modal.load($remote);
}
);
Finally, in the remote content, you need to put the entire structure to work.
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title"></h4>
</div>
<div class="modal-body">
</div>
<div class="modal-footer">
<a href="#" class="btn btn-white" data-dismiss="modal">Close</a>
<a href="#" class="btn btn-primary">Button</a>
<a href="#" class="btn btn-primary">Another button...</a>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
Javascript will throw an exception if you attempt to use a break;
statement inside an if else. It is used mainly for loops. You can "break" out of an if else statement with a condition, which does not make sense to include a "break" statement.

I had the same problem and was able to run a schema-less query using an existing Mongoose connection with the code below. I've added a simple constraint 'a=b' to show where you would add such a constraint:
var action = function (err, collection) {
// Locate all the entries using find
collection.find({'a':'b'}).toArray(function(err, results) {
/* whatever you want to do with the results in node such as the following
res.render('home', {
'title': 'MyTitle',
'data': results
});
*/
});
};
mongoose.connection.db.collection('question', action);
You could use euclidean distance from the point highest and nearest the viewer, except that is not quite right. It results in spherical sort order. You can straighten that out by looking from further away. Further away the curvature becomes flattened out. So just add say 1000 to each of the x,y and z components to give x',y' and z'. The sort on x'*x'+y'*y'+z'*z'.
If you want to loop over what you "find", you should use this:
find . -type f -name '*.*' -print0 | while IFS= read -r -d '' file; do
printf '%s\n' "$file"
done

Another way to escape quotes (though probably not preferable), which I've found used in certain places is to use multiple double-quotes. For the purpose of making other people's code legible, I'll explain.
Here's a set of basic rules:
program param1 param2 param 3
will pass four parameters to program.exe
:param1
, param2
, param
, and 3
.program one two "three and more"
will pass three parameters to program.exe
:one
, two
, and three and more
.hello"to the entire"world
acts as one parameter: helloto the entireworld
."Tim says, ""Hi!"""
will act as one parameter: Tim says, "Hi!"
Thus there are three different types of double-quotes: quotes that open, quotes that close, and quotes that act as plain-text.
Here's the breakdown of that last confusing line:
" open double-quote group T inside ""s i inside ""s m inside ""s inside ""s - space doesn't separate s inside ""s a inside ""s y inside ""s s inside ""s , inside ""s inside ""s - space doesn't separate " close double-quoted group " quote directly follows closer - acts as plain unwrapped text: " H outside ""s - gets joined to previous adjacent group i outside ""s - ... ! outside ""s - ... " open double-quote group " close double-quote group " quote directly follows closer - acts as plain unwrapped text: "
Thus, the text effectively joins four groups of characters (one with nothing, however):
Tim says,
is the first, wrapped to escape the spaces
"Hi!
is the second, not wrapped (there are no spaces)
is the third, a double-quote group wrapping nothing
"
is the fourth, the unwrapped close quote.
As you can see, the double-quote group wrapping nothing is still necessary since, without it, the following double-quote would open up a double-quoted group instead of acting as plain-text.
From this, it should be recognizable that therefore, inside and outside quotes, three double-quotes act as a plain-text unescaped double-quote:
"Tim said to him, """What's been happening lately?""""
will print Tim said to him, "What's been happening lately?"
as expected. Therefore, three quotes can always be reliably used as an escape.
However, in understanding it, you may note that the four quotes at the end can be reduced to a mere two since it technically is adding another unnecessary empty double-quoted group.
Here are a few examples to close it off:
program a b REM sends (a) and (b) program """a""" REM sends ("a") program """a b""" REM sends ("a) and (b") program """"Hello,""" Mike said." REM sends ("Hello," Mike said.) program ""a""b""c""d"" REM sends (abcd) since the "" groups wrap nothing program "hello to """quotes"" REM sends (hello to "quotes") program """"hello world"" REM sends ("hello world") program """hello" world"" REM sends ("hello world") program """hello "world"" REM sends ("hello) and (world") program "hello ""world""" REM sends (hello "world") program "hello """world"" REM sends (hello "world")
Final note: I did not read any of this from any tutorial - I came up with all of it by experimenting. Therefore, my explanation may not be true internally. Nonetheless all the examples above evaluate as given, thus validating (but not proving) my theory.
I tested this on Windows 7, 64bit using only *.exe calls with parameter passing (not *.bat, but I would suppose it works the same).
See also boost::format:
#include <boost/format.hpp>
std::string var = (boost::format("somtext %s sometext %s") % somevar % somevar).str();
For me, it was just a matter of marking the directory as a source root.
This worked for me:
dict = {1: 'a', 2: '', 3: 'b', 4: '', 5: '', 6: 'c'}
for key, value in list(dict.items()):
if (value == ''):
del dict[key]
print(dict)
# dict = {1: 'a', 3: 'b', 6: 'c'}
Casting the dictionary items to list creates a list of its items, so you can iterate over it and avoid the RuntimeError
.
I've found that you can move div elements to the next line simply by setting the property
Display: block;
On each div.
I come with this to change video source dynamically. "canplay" event sometime doesn't fire in Firefox so i have added "loadedmetadata". Also i pause previous video if there is one...
var loadVideo = function(movieUrl) {
console.log('loadVideo()');
$videoLoading.show();
var isReady = function (event) {
console.log('video.isReady(event)', event.type);
video.removeEventListener('canplay', isReady);
video.removeEventListener('loadedmetadata', isReady);
$videoLoading.hide();
video.currentTime = 0;
video.play();
},
whenPaused = function() {
console.log('video.whenPaused()');
video.removeEventListener('pause', whenPaused);
video.addEventListener('canplay', isReady, false);
video.addEventListener('loadedmetadata', isReady, false); // Sometimes Firefox don't trigger "canplay" event...
video.src = movieUrl; // Change actual source
};
if (video.src && !video.paused) {
video.addEventListener('pause', whenPaused, false);
video.pause();
}
else whenPaused();
};
26 % 7 (you will get remainder)
26 / 7 (you will get divisor can be float value )
26 // 7 (you will get divisor only integer value) )
You can use VC CRT Heap-Check macros for _CrtSetDbgFlag: _CRTDBG_CHECK_ALWAYS_DF or _CRTDBG_CHECK_EVERY_16_DF.._CRTDBG_CHECK_EVERY_1024_DF.
Use the web browser control. This requires Adobe reader to be installed but most likely you have it anyway. Set the UrL of the control to the file location.
Your going to use the checkbox1.checked
property in your if statement, this returns true or false depending on weather it is checked or not.
both seem to be working.

I have to vote -1 for the libraries hosted on Google. They are collecting data, google analytics style, with their wrappers around these libraries. At a minimum, I don't want a client browser doing more than I'm asking it to do, much less anything else on the page. At worse, this is Google's "new version" of not being evil -- using unobtrusive javascript to gather more usage data.
Note: if they've changed this practice, super. But the last time I considered using their hosted libraries, I monitored the outbound http traffic on my site, and the periodic calls out to google servers were not something I expected to see.

@roo: Encapsulation is not broken here because the class itself dictates who can access its private members. Encapsulation would only be broken if this could be caused from outside the class, e.g. if your operator <<

This is the first answer when Googling 'require': cannot load such file -- ubygems (LoadError)
after Google autocorrected "ubygems" to "rubygems". Turns out this was an intentional change between Ruby 2.4 and 2.5 (Bug #14322). Scripts that detect the user gems directory without taking into account the ruby version will most likely fail.

Ruby 2.5

Your makefile should ideally be named makefile
, not make
. Note that you can call your makefile anything you like, but as you found, you then need the -f
option with make
to specify the name of the makefile. Using the default name of makefile
just makes life easier.
You use runas
to launch a program as a specific user:
runas /user:Administrator Example1Server.exe
The name
property is marked as protected
. This was added in TypeScript 1.3 and is now firmly established.
The makeSound
method is marked as abstract
, as is the class. You cannot directly instantiate an Animal
now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.
abstract class Animal {
constructor(protected name: string) { }
abstract makeSound(input : string) : string;
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name: string) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:
class Animal {
constructor(public name) { }
makeSound(input : string) : string {
throw new Error('This method is abstract');
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
You can use the toLowerCase()
method:
public boolean contains( String haystack, String needle ) {
haystack = haystack == null ? "" : haystack;
needle = needle == null ? "" : needle;
// Works, but is not the best.
//return haystack.toLowerCase().indexOf( needle.toLowerCase() ) > -1
return haystack.toLowerCase().contains( needle.toLowerCase() )
}
Then call it using:
if( contains( str1, str2 ) ) {
System.out.println( "Found " + str2 + " within " + str1 + "." );
}
Notice that by creating your own method, you can reuse it. Then, when someone points out that you should use contains
instead of indexOf
, you have only a single line of code to change.
Also you can use -
Private Const SrlNumber As Integer = 910
Private Sub Workbook_Open()
If SrlNumber > 900 Then
MsgBox "This serial number is valid"
Else
MsgBox "This serial number is not valid"
End If
End Sub

Why not grab them from dependencies
in package.json
?
Of course, this will only give you the ones you actually saved, but you should be doing that anyway.
console.log(Object.keys(require('./package.json').dependencies));
If, like me, you are still using the browser version (which will be deprecated soon), have you tried the "Code" button?
This should generate a snippet which contains the entire request Postman is firing. You can even choose the language for the snippet. I find it quite handy when I need to debug stuff.
Hope this helps.
I would do something like:
filename = "mynumbers.txt"
mynumbers = []
with open(filename) as f:
for line in f:
mynumbers.append([int(n) for n in line.strip().split(',')])
for pair in mynumbers:
try:
x,y = pair[0],pair[1]
# Do Something with x and y
except IndexError:
print "A line in the file doesn't have enough entries."
The with open is recommended in http://docs.python.org/tutorial/inputoutput.html since it makes sure files are closed correctly even if an exception is raised during the processing.
You mentioned that you're interested in the equality of the contents of the list (and didn't mention order). So containsExactlyInAnyOrder
from AssertJ is a good fit. It comes packaged with spring-boot-starter-test
, for example.
From the AssertJ docs ListAssert#containsExactlyInAnyOrder:
Verifies that the actual group contains exactly the given values and nothing else, in any order. Example:
// an Iterable is used in the example but it would also work with an array
Iterable<Ring> elvesRings = newArrayList(vilya, nenya, narya, vilya);
// assertion will pass
assertThat(elvesRings).containsExactlyInAnyOrder(vilya, vilya, nenya, narya);
// assertion will fail as vilya is contained twice in elvesRings.
assertThat(elvesRings).containsExactlyInAnyOrder(nenya, vilya, narya);
First of all, if you want it displayed on a PHP form, the medium is HTML and so a new line will be rendered with the <br />
tag. Check the source HTML of the page - you may possibly have the new line rendered just as a line break, in which case your problem is simply one of translating the text for output to a web browser.
There is a bit of a contradiction in the question's title and the content. The title speaks of a parent div, but the question makes it sound like you want two sibling divs (navigation and content) to be the same height.
Do you (a) want both navigation and content to be 100% the height of main, or (b) want navigation and content to be be same height?
I'll assume (b)...if that is so, I don't think you will be able to do it given your current page structure (at least, not with pure CSS and no scripting). You would probably need to do something like:
<main div>
<content div>
<navigation div></div>
</div>
</div>
and set the content div to have a left margin of whatever the width of the navigation pane is. That way, the content's content is to the right of the navigation and you can set the navigation div to be 100% of the content's height.
EDIT: I'm doing this completely in my head, but you would probably also need to set the navigation div's left margin to a negative value or set it's absolute left to 0 to shove it back to the far left. Problem is, there are many ways to pull this off but not all of them are going to be compatible with all browsers.
Firstly, Stack structure can be examined. For the launch mode:singleTop
If an instance of the same activity is already on top of the task stack, then this instance will be reused to respond to the intent.
All activities are hold in the stack("first in last out") so if your current activity is at the top of stack and if you define it in the manifest.file as singleTop
android:name=".ActivityA"
android:launchMode="singleTop"
if you are in the ActivityA recreate the activity it will not enter onCreate will resume onNewIntent() and you can see by creating a notification Not:If you do not implement onNewIntent(Intent) you will not get new intent.
Intent activityMain = new Intent(ActivityA.this,
ActivityA.class);
activityMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(activityMain);
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
notify("onNewIntent");
}
private void notify(String methodName) {
String name = this.getClass().getName();
String[] strings = name.split("\\.");
Notification noti = new Notification.Builder(this)
.setContentTitle(methodName + "" + strings[strings.length - 1])
.setAutoCancel(true).setSmallIcon(R.drawable.ic_launcher)
.setContentText(name).build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify((int) System.currentTimeMillis(), noti);
}
The main difference what i have observed was that abstract class provides us with some common behaviour implemented already and subclasses only needs to implement specific functionality corresponding to them. where as for an interface will only specify what tasks needs to be done and no implementations will be given by interface. I can say it specifies the contract between itself and implemented classes.

From what I tested:
Session.Abandon(); // Does nothing
Session.Clear(); // Removes the data contained in the session
Example:
001: Session["test"] = "test";
002: Session.Abandon();
003: Print(Session["test"]); // Outputs: "test"
Session.Abandon does only set a boolean flag in the session-object to true. The calling web-server may react to that or not, but there is NO immediate action caused by ASP. (I checked that myself with the .net-Reflector)
In fact, you can continue working with the old session, by hitting the browser's back button once, and continue browsing across the website normally.
So, to conclude this: Use Session.Clear() and save frustration.
Remark: I've tested this behaviour on the ASP.net development server. The actual IIS may behave differently.
Swift 2.0:
Implement viewForHeaderInSection, like so:
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let sectionTitle: String = self.tableView(tableView, titleForHeaderInSection: section)!
if sectionTitle == "" {
return nil
}
let title: UILabel = UILabel()
title.text = sectionTitle
title.textColor = UIColor(red: 0.0, green: 0.54, blue: 0.0, alpha: 0.8)
title.backgroundColor = UIColor.clearColor()
title.font = UIFont.boldSystemFontOfSize(15)
return title
}
Implement willDisplayHeaderView, like so:
override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
if let view = view as? UITableViewHeaderFooterView {
view.backgroundView?.backgroundColor = UIColor.blueColor()
view.textLabel!.backgroundColor = UIColor.clearColor()
view.textLabel!.textColor = UIColor.whiteColor()
view.textLabel!.font = UIFont.boldSystemFontOfSize(15)
}
}
Remember: If you're using static cells, the first section header is padded higher than other section headers due to the top of the UITableView; to fix this:
Implement heightForHeaderInSection, like so:
override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 30.0 // Or whatever height you want!
}
I was also plagued by this error, and after trying all the other answers, magically found the following solution:
Delete package-lock.json and the node_modules folder, then run npm install
again.
If that doesn't work, try running these in order:
npm install
npm cache clean --force
npm install -g npm
npm install
(taken from @Thisuri's answer and @Mathias Falci's comment respectively)
and then re-deleting the above files and re-running npm install
.
Worked for me!
for (int i = 0; i < list.length; i++) {
if (list.get(i) .getName().equalsIgnoreCase("myName")) {
System.out.println(i);
break;
}
}
If you have a JS array of JSON objects:
var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];
and you want an array of objects:
// JavaScript array of JavaScript objects
var objs = s.map(JSON.parse);
// ...or for older browsers
var objs=[];
for (var i=s.length;i--;) objs[i]=JSON.parse(s[i]);
// ...or for maximum speed:
var objs = JSON.parse('['+s.join(',')+']');
See the speed tests for browser comparisons.
If you have a single JSON string representing an array of objects:
var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';
and you want an array of objects:
// JavaScript array of JavaScript objects
var objs = JSON.parse(s);
If you have an array of objects:
// A JavaScript array of JavaScript objects
var s = [{"Select":"11", "PhotoCount":"12"},{"Select":"21", "PhotoCount":"22"}];
…and you want JSON representation for it, then:
// JSON string representing an array of objects
var json = JSON.stringify(s);
…or if you want a JavaScript array of JSON strings, then:
// JavaScript array of strings (that are each a JSON object)
var jsons = s.map(JSON.stringify);
// ...or for older browsers
var jsons=[];
for (var i=s.length;i--;) jsons[i]=JSON.stringify(s[i]);
There are some more actions you should consider:
Remove Registry Entries for MS Distributed Transaction Coordinator (MSDTC)
Note: on the Internet I found this step only at a single (private) page. I don't know if it is required/working or if it breaks anything on your PC.
HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI
OracleOciLib
, OracleSqlLib
, and OracleXaLib
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI
OracleOciLib
, OracleSqlLib
, and OracleXaLib
Otherwise these files, if they exist, will still be in use next time you reboot, and unable to be deleted.
Remove environment variable ORACLE_HOME
, ORACLE_BASE
, TNS_ADMIN
, NLS_LANG
if exist
Check also Oracle doc to find all Oracle related environment variables, however apart from variables listed above they are very rarely used on Windows Client: Oracle Environment Variables
Unregister oci.dll
Enter regsvr32 /u oci.dll
, resp. %windir%\SysWOW64\regsvr32 /u oci.dll
In some cases the file %ORACLE_HOME%\bin\oci.dll
is locked and you cannot delete it. In such case rename the file (e.g. to oci.dll.x) and reboot the PC, afterwards you can delete it.
Remove Oracle .NET assemblies from Global Assembly Cache (GAC). You do this typically with the gacutil utility, if available on your system. Would be like this:
gacutil /u Policy.10.1.Oracle.DataAccess
gacutil /u Policy.10.2.Oracle.DataAccess
gacutil /u Policy.1.102.Oracle.DataAccess
gacutil /u Policy.1.111.Oracle.DataAccess
gacutil /u Policy.2.102.Oracle.DataAccess
gacutil /u Policy.2.111.Oracle.DataAccess
gacutil /u Policy.2.112.Oracle.DataAccess
gacutil /u Policy.2.121.Oracle.DataAccess
gacutil /u Policy.2.122.Oracle.DataAccess
gacutil /u Policy.4.112.Oracle.DataAccess
gacutil /u Policy.4.121.Oracle.DataAccess
gacutil /u Policy.4.122.Oracle.DataAccess
gacutil /u Oracle.DataAccess
gacutil /u Oracle.DataAccess.resources
gacutil /u Policy.4.121.Oracle.ManagedDataAccess
gacutil /u Policy.4.122.Oracle.ManagedDataAccess
gacutil /u Oracle.ManagedDataAccess
gacutil /u Oracle.ManagedDataAccess.resources
gacutil /u Oracle.ManagedDataAccessDTC
gacutil /u Oracle.ManagedDataAccessIOP
gacutil /u Oracle.ManagedDataAccess.EntityFramework
Entry System.Data.OracleClient
should not be removed, this one is installed by Microsoft - not an Oracle component!
Instead of gacutil /u ...
you can also use OraProvCfg /action:ungac /providerpath:...
if OraProvCfg is still available on your system. You may find it at %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe
.
With a text editor, open XML Config file %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
and delete branch <oracle.manageddataaccess.client>
, if existing.
Do the same with:
%SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config
%SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\web.config
Instead of editing the XML Config file manually you can also run (if OraProvCfg.exe is still available on your system):
%ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319
%ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319

Here's some that I needed to include the date-time stamp in the folder name for dumping files from a web scraper.
# import time and OS modules to use to build file folder name

folder_to_save_files = drive_letter + folder_name + folder_time
# IF no such folder exists, create one automatically
if not os.path.exists(folder_to_save_files):

Hello guys i am using this technique to get the values from the selected dropdown list and it is working like charm.
var methodvalue = $("#method option:selected").val();
try,
str_list = " ".join([str(ele) for ele in numlist])
this statement will give you each element of your list in string
format
print("The list now looks like [{0}]".format(str_list))
and,
change print(numlist.pop(2)+" has been removed")
to
print("{0} has been removed".format(numlist.pop(2)))
as well.
In Swift 4.2 I would do something like that:
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let yourVC = segue.destination as? YourViewController {
yourVC.yourData = self.someData
}
}
@Html.DropDownListFor(m => m.SelectedValue,Your List,"ID","Values")
Here Value is that object of model where you want to save your Selected Value
On Linux, see constant INET6_ADDRSTRLEN
(include <arpa/inet.h>
, see man inet_ntop
). On my system (header "in.h"):
#define INET6_ADDRSTRLEN 46
The last character is for terminating NULL, as I belive, so the max length is 45, as other answers.
NetBeans Free! Plus, the best functionality of all offerings. Includes inline database connections, code completion, syntax checking, color coding, split views etc. Downside: It's a memory hog on the Mac. Be prepared to allow half a gig of memory then you'll need to shut down and restart.
Komodo A step above a Text Editor. Does not support database connections or split views. Color coding and syntax checking are there to an extent. The project control on Komodo is very unwieldy and strange compared to the other IDEs.
Aptana The perfect solution. Eclipsed based and uses the Aptana PHP plug in. Real time syntax checking, word wrap, drag and drop split views, database connections and a slew of other excellent features. Downside: Not a supported product any more. Aptana Studio 2.0+ uses PDT which is a watered down, under-developed (at present) php plug in.
Zend Studio - Almost identical to Aptana, except no word wrap and you can't change alot of the php configuration on the MAC apparently due to bugs.
Coda Created by Panic, Coda has nice integration with source control and their popular FTP client, transmit. They also have a collaboration feature which is cool for pair-programming.
PhpEd with Parallels or Wine. The best IDE for Windows has all the feature you could need and is worth the effort to pass it through either Parallels or Wine.
Dreamweaver Good for Javascript/HTML/CSS, but only marginal for PHP. There is some color coding, but no syntax checking or code completion native to the package. Database connections are supported, and so are split views.
I'm using NetBeans, which is free, and feature rich. I can deal with the memory issues for a while, but it could be slow coming to the MAC.

See the Locale.getLanguage()
, Locale.getCountry()
... Store this combination in the database instead of the "programatic name"
...
When you want to build the Locale back, use public Locale(String language, String country)
Here is a sample code :)
// May contain simple syntax error, I don't have java right now to test..
// but this is a bigger picture for your algo...
public String localeToString(Locale l) {
return l.getLanguage() + "," + l.getCountry();
}
public Locale stringToLocale(String s) {
StringTokenizer tempStringTokenizer = new StringTokenizer(s,",");
if(tempStringTokenizer.hasMoreTokens())
String l = tempStringTokenizer.nextElement();
if(tempStringTokenizer.hasMoreTokens())
String c = tempStringTokenizer.nextElement();
return new Locale(l,c);
}
I also faced problem like this and i set this.
@XmlRootElement(name="yourRootElementName")
@XmlAccessorType(XmlAccessType.FIELD)
This will work 100%
Also encounter this in select2 dropdown plugin in Laravel. Changing the value as suggested by Alfred Wallace from
this.element.addEventListener(t, e, !1)
to
this.element.addEventListener(t, e, { passive: true} )
solves the issue. Why he has a down vote, I don't know but it works for me.
I ran into issues on one of my servers querying MSDB tables (aka code listed above) as one of my jobs would come up running, but it was not. There is a system stored procedure that returns the execution status, but one cannot do a insert exec statement without an error.

It's the response code a SIP User Agent Server (UAS) will send to the client after the client sends a CANCEL request for the original unanswered INVITE request (yet to receive a final response).
Here is a nice CANCEL SIP Call Flow illustration.
You get "close existing connections to destination database" option only in "Databases context >> Restore Wizard" and NOT ON context of any particular database.
Right Click on the Databases under your Server-Name as shown below:
and select the option: "Restore Database..." from it.
In the "Restore Database" wizard,
Here you can find the checkbox saying, "close existing connections to destination database"
Just check it, and you can proceed for the restore operation.
It automatically will resume all connections after completion of the Restore.
For me, I used margin-left: auto; which is more responsive with horizontal resizing.
The below is a little slow, but it gives a nicely formatted list of packages that pip
is aware of. That is to say, not all of them were installed "by" pip, but all of them should be able to be upgraded by pip.
$ pip search . | egrep -B1 'INSTALLED|LATEST'
The reason it is slow is that it lists the contents of the entire pypi repo. I filed a ticket suggesting pip list
provide similar functionality but more efficiently.
Sample output: (restricted the search to a subset instead of '.' for all.)
$ pip search selenium | egrep -B1 'INSTALLED|LATEST'

In my case (sam problem, but other packages) there was no version dependency. A sequence of pip uninstall and pip insstall did help.
A simple way is to got to http://websitename.com:174, and you will be entering through a different port.
The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.
The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.
The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.
Edit: Also worth a look - kashif's comment about json-streamer
and Henrik Heino's comment about bigjson
.
Or another old school solution:
var someArray = [9, 2, 5];
let i = 0;
for (var item of someArray) {
console.log(item); // 9,2,5
i++;
}
I had this problem just last week. I had to serialize a PDF file and send it, inside an XML file, to a server.
If you're using .NET, you can convert a binary file directly to a base64 string and stick it inside an XML element.
string base64 = Convert.ToBase64String(File.ReadAllBytes(fileName));
Or, there is a method built right into the XmlWriter object. In my particular case, I had to include Microsoft's datatype namespace:
StringBuilder sb = new StringBuilder();
System.Xml.XmlWriter xw = XmlWriter.Create(sb);
xw.WriteStartElement("doc");
xw.WriteStartElement("serialized_binary");
xw.WriteAttributeString("types", "dt", "urn:schemas-microsoft-com:datatypes", "bin.base64");
byte[] b = File.ReadAllBytes(fileName);
xw.WriteBase64(b, 0, b.Length);
xw.WriteEndElement();
xw.WriteEndElement();
string abc = sb.ToString();
The string abc looks something that looks like this:
<?xml version="1.0" encoding="utf-16"?>
<doc>
<serialized_binary types:dt="bin.base64" xmlns:types="urn:schemas-microsoft-com:datatypes">
JVBERi0xLjMKJaqrrK0KNCAwIG9iago8PCAvVHlwZSAvSW5mbw...(plus lots more)
</serialized_binary>
</doc>
Once you have your key stored in a PEM file, you can read it back easily using PemObject and PemReader classes provided by BouncyCastle, as shown in this this tutorial.
Create a PemFile class that encapsulates file handling:
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import org.bouncycastle.util.io.pem.PemObject;
import org.bouncycastle.util.io.pem.PemReader;
public class PemFile {
private PemObject pemObject;
public PemFile(String filename) throws FileNotFoundException, IOException {
PemReader pemReader = new PemReader(new InputStreamReader(
new FileInputStream(filename)));
try {
this.pemObject = pemReader.readPemObject();
} finally {
pemReader.close();
}
}
public PemObject getPemObject() {
return pemObject;
}
}
Then instantiate private and public keys as usual:
import java.io.FileNotFoundException;
import java.io.IOException;
import java.security.KeyFactory;
import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.security.Security;
import java.security.spec.InvalidKeySpecException;

You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:
if (dsnt<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
}
To put it more simply, if you have:
if(condition == TRUE) x <- TRUE
else x <- FALSE
Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:
if(condition == TRUE) {x <- TRUE
} else {x <- FALSE}
You probably are going to want to use the following declaration:
height: 100%;
This will set the div's height to 100% of its containers height, which will make it fill the parent div.
I open a text editor, in my case I used Atom. Paste this code
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
and save as
helloworld.js
in
c:\xampp\htdocs\myproject
directory. Next I open node.js commamd prompt enter
cd c:\xampp\htdocs\myproject
next
node helloworld.js
next I open my chrome browser and I type
http://localhost:1337
and there it is.
You can use Get-Member

http://getbootstrap.com/javascript/#modals shows an event for when a modal is hidden. Just tap into that:
$('#modal1').on('hidden.bs.modal', function (e) {
$(this)
.find("input,textarea,select")
.val('')
.end()
.find("input[type=checkbox], input[type=radio]")
.prop("checked", "")
.end();
})
I would suggest the above as it bind the clearing to the modal itself instead of the close button, but I realize this does not address your specific question. You could use the same clearing logic bound to the dismiss buttons:
$('[data-dismiss=modal]').on('click', function (e) {
var $t = $(this),
target = $t[0].href || $t.data("target") || $t.parents('.modal') || [];
$(target)
.find("input,textarea,select")
.val('')
.end()
.find("input[type=checkbox], input[type=radio]")
.prop("checked", "")
.end();
})
Here is a very basic but modern implementation of required radio buttons with native HTML5 validation:
fieldset {
display: block;
margin-left: 0;
margin-right: 0;
padding-top: 0;
padding-bottom: 0;
padding-left: 0;
padding-right: 0;
border: none;
}
body {font-size: 15px; font-family: serif;}
input {
background: transparent;
border-radius: 0px;
border: 1px solid black;
padding: 5px;
box-shadow: none!important;
font-size: 15px; font-family: serif;
}
input[type="submit"] {padding: 5px 10px; margin-top: 5px;}
label {display: block; padding: 0 0 5px 0;}
form > div {margin-bottom: 1em; overflow: auto;}
.hidden {
opacity: 0;
position: absolute;
pointer-events: none;
}
.checkboxes label {display: block; float: left;}
input[type="radio"] + span {
display: block;
border: 1px solid black;
border-left: 0;
padding: 5px 10px;
}
label:first-child input[type="radio"] + span {border-left: 1px solid black;}
input[type="radio"]:checked + span {background: silver;}

Although I am a big fan of the minimalistic approach of using native HTML5 validation, you might want to replace it with Javascript validation on the long run. Javascript validation gives you far more control over the validation process and it allows you to set real classes (instead of pseudo classes) to improve the styling of the (in)valid fields. This native HTML5 validation can be your fall-back in case of broken (or lack of) Javascript. You can find an example of that here, along with some other suggestions on how to make Better forms, inspired by Andrew Cole.
Your JavaScript is fine, unless you have other scripts running on this page which may corrupt everything. You may check this using Firebug.
I've now tested a bit and it really seems that ASP.net ignores disabled controls. Basically the postback is issued, but probably the framework ignores such events since it "assumes" that a disabled button cannot raise any postback and so it ignores possibly attached handlers. Now this is just my personal reasoning, one could use Reflector to check this in more depth.
As a solution you could really try to do the disabling at a later point, basically you delay the control.disabled = "disabled"
call using a JavaTimer or some other functionality. In this way 1st the postback to the server is issued before the control is being disabled by the JavaScript function. Didn't test this but it could work
Why not just display it in the user's web browser?
Use -d
(full list of file tests)
if (-d "cgi-bin") {
# directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
# cgi-bin exists but is not a directory
}
else {
# nothing called cgi-bin exists
}
As a note, -e
doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f
.

java.util.Date
is independent of the timezone. When you print cal_Two
though the Calendar
instance has got its timezone set to UTC
, cal_Two.getTime()
would return a Date
instance which does not have a timezone (and is always in the default timezone)
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());
System.out.println(cal_Two.getTimeZone());
Output:
Sat Jan 25 16:40:28 IST 2014
sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
From the javadoc of TimeZone.setDefault()
Sets the TimeZone that is returned by the getDefault method. If zone is null, reset the default to the value it had originally when the VM first started.
Hence, moving your setDefault()
before cal_Two
is instantiated you would get the correct result.
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());
Calendar cal_Three = Calendar.getInstance();
System.out.println(cal_Three.getTime());

In the MathMethod.py file:
from multipledispatch import dispatch
@dispatch(int, int)
def Add(a, b):
return a + b
@dispatch(int, int, int)
def Add(a, b, c):
return a + b + c
@dispatch(int, int, int, int)
def Add(a, b, c, d):
return a + b + c + d
In the Main.py file
import MathMethod as MM
print(MM.Add(200, 1000, 1000, 200))
We can overload the method by using multipledispatch.
It is possible to avoid constructor annotations with jdk8 where optionally the compiler will introduce metadata with the names of the constructor parameters. Then with jackson-module-parameter-names module Jackson can use this constructor. You can see an example at post Jackson without annotations
First you have to add System.Configuration
reference to your project and then use below code to get connection string.
_connectionString = ConfigurationManager.ConnectionStrings["MYSQLConnection"].ConnectionString.ToString();
You can set a callback function for the onSubmit event of the form and check the contents of each field. If it contains nothing you can then fill it with the string "empty":
<form name="my_form" action="validate.php" onsubmit="check()">
<input type="text" name="text1" />
<input type="submit" value="submit" />
</form>
and in your js:
function check() {
if(document.forms["my_form"]["text1"].value == "")
document.forms["my_form"]["text1"].value = "empty";
}
At the Maven repo, there are samples to add the dependency in maven, sbt, gradle, etc.
https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore/4.4.11
ie for Maven, you just create a project, for example
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
then look at the pom.xml, then at the library at the dependencies xml element:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>4.4.11</version>
</dependency>
For sbt do something like
sbt new scala/hello-world.g8
then edit the build.sbt to add the library
libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"

Common Table Expressions let you define what are essentially views that last only within the scope of your select, insert, update and delete statements. Depending on what you need to do they can be terribly useful.
I am new to android but I had a similar situation. I did what @Delyan suggested and also used android:background="@null" in the xml layout file.
It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:
[bits 32]
.
.
and [ebp-4], 0
Also add this bit of code to your form to allow it to be draggable still.
Just add it right before the constructor (the method that calls InitializeComponent()
private const int WM_NCHITTEST = 0x84;
private const int HTCLIENT = 0x1;
private const int HTCAPTION = 0x2;
///
/// Handling the window messages
///
protected override void WndProc(ref Message message)
{
base.WndProc(ref message);
if (message.Msg == WM_NCHITTEST && (int)message.Result == HTCLIENT)
message.Result = (IntPtr)HTCAPTION;
}
That code is from: https://jachman.wordpress.com/2006/06/08/enhanced-drag-and-move-winforms-without-having-a-titlebar/
Now to get rid of the title bar but still have a border combine the code from the other response:
this.ControlBox = false;
this.Text = String.Empty;
with this line:
this.FormBorderStyle = FormBorderStyle.FixedSingle;
Put those 3 lines of code into the form's OnLoad event and you should have a nice 'floating' form that is draggable with a thin border (use FormBorderStyle.None if you want no border).
Tom's solution with the Exec Maven Plugin is much better, but still more complicated than it needs to be. For me it's as simple as:
MVN_VERSION=$(mvn -q \
-Dexec.executable=echo \
-Dexec.args='${project.version}' \
--non-recursive \
exec:exec)
You can avoid having your filename embedded in the NUMOFLINES variable by using redirection from JAVA_TAGS_FILE, rather than passing the filename as an argument to wc. For example:
NUMOFLINES=$(wc -l < "$JAVA_TAGS_FILE")
The wc utility will not print the name of the file in its output if input is taken from a pipe or redirection operator. Consider these various examples:
# wc shows filename when the file is an argument
$ wc -l /etc/passwd
41 /etc/passwd
# filename is ignored when piped in on standard input
$ cat /etc/passwd | wc -l
41
# unusual redirection, but wc still ignores the filename
$ < /etc/passwd wc -l
41
# typical redirection, taking standard input from a file
$ wc -l < /etc/passwd
41
As you can see, the only time wc will print the filename is when its passed as an argument, rather than as data on standard input. In some cases, you may want the filename to be printed, so it's useful to understand when it will be displayed.
FAT32
along with FAT16
and FAT12
are File System Types, but vfat
along with umsdos
and msdos
are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos
driver don't have long filenames (they are 8.3 format). vfat
is the most common driver for mounting FAT32 file systems nowadays.
Source: this wikipedia article
Output of commands like df
and lsblk
indeed show vfat
as the File System Type. But sudo file -sL /dev/<partition>
shows FAT (32 bit)
if a File System is FAT32.
You can confirm vfat
is a module and not a File System Type by running modinfo vfat
.
I can think of a handy use for the custom tag "init"
. Include a JavaScript expression that gets evaluated at document.onLoad()
time and provides a value for the tag, e.g.
<p><p>The UTC date is <span init="new Date().toUTCString()">?</span>.<p></p>
Some boilerplate JavaScript code would scan all the tags in the DOM at document.onload()
time looking for the init attributes, evaluating the expressions that they contain, and assigning them to the containing tag's innerHTML. This would give HTML some of the power of JSP, PHP etc. Currently we have to split the HTML markup and the JavaScript code that illuminates it. Bugs love split code.
You all should definitely check this new php profiler.
https://github.com/NoiseByNorthwest/php-spx
It redefines the way of how php profilers collects and presents the result. Instead of outputting just a total number of particular function calls and total time spent of executing it - PHP-SPX presents the whole timeline of request execution in a perfectly readable way. Below is the screen of GUI it provides.
From the comments, the problem was caused by using dlls that were built with Visual Studio 2013 in a project compiled with Visual Studio 2012. The reason for this was a third party library named the folders containing the dlls vc11, vc12. One has to be careful with any system that uses the compiler version (less than 4 digits) since this does not match the version of Visual Studio (except for Visual Studio 2010).
The Microsoft C++ runtime dlls use a 2 or 3 digit code also based on the compiler version not the version of Visual Studio.
There is binary compatibility between Visual Studio 2015, 2017 and 2019.
You're trying to do &(2), &(4)
which won't work
#romtest {

&:nth-child(4) {//your styles here}
&:nth-child(6) {//your styles here}
}
}

Just use DataRow.IsNull. It has overrides accepting a column index, a column name, or a DataColumn object as parameters.
Example using the column index:
if (table.rows[0].IsNull(0))
{
//Whatever I want to do
}
And although the function is called IsNull
it really compares with DbNull
(which is exactly what you need).
What if I want to check for DbNull but I don't have a DataRow? Use Convert.IsDBNull.
In your image you've putting the padding outside the child. This is not the case. Padding adds to the width of an element, so if you add padding and give it a width of 100% it will have a width of 100% + padding. In order to what you are wanting you just need to either add padding to the parent div, or add a margin to the inner div. Because divs are block-level elements they will automatically expand to the width of their parent.
In order to do this, you need to have a small program that displays a messagebox and run that from your batch file.
You could open a console window that displays a prompt though, but getting a GUI message box using cmd.exe and friends only is not possible, AFAIK.
Importing inside a function will effectively import the module once.. the first time the function is run.
It ought to import just as fast whether you import it at the top, or when the function is run. This isn't generally a good reason to import in a def. Pros? It won't be imported if the function isn't called.. This is actually a reasonable reason if your module only requires the user to have a certain module installed if they use specific functions of yours...
If that's not he reason you're doing this, it's almost certainly a yucky idea.
On MySQL 5.7 and Ubuntu 16.04, edit the file mysql.cnf.
$ sudo nano /etc/mysql/conf.d/mysql.cnf
Include the sql_mode like the following and save the file.
[mysql]
sql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Observe that, in my case, I removed the mode STRICT_TRANS_TABLES and the ONLY_FULL_GROUP_BY.
Doing this, it will save the mode configuration permanently. Differently if you just update the @@sql_mode through MySQL, because it will reset on machine/service restart.
After that, to the modified configuration take in action, restart the mysql service:
$ sudo service mysql restart
Try to access the mysql:
$ mysql -u user_name -p
If you are able to login and access MySQL console, it is ok. Great!
BUT, if like me, you face the error "unknown variable sql_mode", which indicates that sql_mode is an option for mysqld, you will have to go back, edit the file mysql.cnf again and change the [mysql]
to [mysqld]
. Restart the MySQL service and do a last test trying to login on MySQL console. Here it is!
I had this problem for our FSharp targets (FSharpTargetsPath was empty).
Many of the paths are built with reference to the VS version.
For various reasons, our build runs with system privileges, and the environment variable "VisualStudioVersion" was only set (by the VS 2013 installer) at the "user" level - which is fair enough.
Ensure that the "VisualStudioVersion
" environment variable is set to "12.0
" at the level (System or User) that you are running at.
Try like
HTML in PHP :
echo "<a href='".$link_address."'>Link</a>";
Or even you can try like
echo "<a href='$link_address'>Link</a>";
Or you can use PHP in HTML like
PHP in HTML :
<a href="<?php echo $link_address;?>"> Link </a>
Per the JQuery documentation, .get()
only takes the url
, data
(content), dataType
, and success
callback as its parameters. What you're really looking to do here is modify the jqXHR object before it gets sent. With .ajax()
, this is done with the beforeSend()
method. But since .get()
is a shortcut, it doesn't allow it.
It should be relatively easy to switch your .ajax()
calls to .get()
calls though. After all, .get()
is just a subset of .ajax()
, so you can probably use all the default values for .ajax()
(except, of course, for beforeSend()
).
Edit:
::Looks at Jivings' answer::
Oh yeah, forgot about the cache
parameter! While beforeSend()
is useful for adding other headers, the built-in cache
parameter is far simpler here.
Correct the ORACLE_HOME path.
There could be two oracle clients in the system.
I had the same issue, the reason being my ORACLE_HOME was pointed to the oracle installation which was not having the tns.ora file.
Changing the ORACLE_HOME to the Oracle directory which is having the tns.ora solved it.
tns.ora lies in client2\network\admin\
You can make text or words Bold
with using <b>Text</b>
tag.
You can also use <strong>Text</strong>
tag
Head tags <h1>
, <h2>
, <h3>
, ... are default bolded tags and make your text Bold by default unless you change their style with CSS
Above tags was available in HTML but if you like to change the style with CSS
you can use
font-weight:bold
What worked here : on the client
1) ssh-add
2) ssh-copy-id user@server
The keys has been created some time ago with plain "ssh-keygen -t rsa" I sw the error message because I copied across my ssh public key from client to server (with ssh-id-copy) without running ssh-add first, since I erroneously assumed I'd added them some time earlier.
Just as normal, using data-original-title
:
Html:
<div rel='tooltip' data-original-title='<h1>big tooltip</h1>'>Visible text</div>
Javascript:
$("[rel=tooltip]").tooltip({html:true});
The html parameter specifies how the tooltip text should be turned into DOM elements. By default Html code is escaped in tooltips to prevent XSS attacks. Say you display a username on your site and you show a small bio in a tooltip. If the html code isn't escaped and the user can edit the bio themselves they could inject malicious code.
This code handles the exponents, floats, and integers, wihtout using regex.
return True if str1.lstrip('-').replace('.','',1).isdigit() or float(str1) else False
SQLExplorer is a great Eclipse plugin or standalone interface that works with many different database systems, either with dedicated drivers or with ODBC.
You need to put your main code on the OnStart
method.
This other SO answer of mine might help.
You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.
EDIT:
Please see also the documentation available here for the OnStart
method at the MSDN where one can read this:
Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

i am use following construction to convert back nl2br
function br2nl( $input ) {
return preg_replace('/<br\s?\/?>/ius', "\n", str_replace("\n","",str_replace("\r","", htmlspecialchars_decode($input))));
}
here i replaced \n
and \r
symbols from $input because nl2br dosen't remove them and this causes wrong output with \n\n
or \r<br>
.
If you want it casted to a specific type you can use this method. Most non primitive types won't by default support direct casting so you will have to handle those accordingly.
public T GetValue<T>(string registryKeyPath, string value, T defaultValue = default(T))
{
T retVal = default(T);
retVal = (T)Registry.GetValue(registryKeyPath, value, defaultValue);
return retVal;
}
var arr = new Array(5);
console.log(arr.length) // 5
You can do pretty much the same as in JavaScript. Try this:
Console.WriteLine(mon + "." + da + "." + yer);
Or you can use WriteLine
as if it were a string.Format
statement by doing:
Console.WriteLine("{0}.{1}.{2}", mon, da, yer);
which is equivalent to:
string.Format("{0}.{1}.{2}", mon, da, yer);
The number of parameters can be infinite, just make sure you correctly index those numbers (starting at 0).
I don’t see what worked for me listed out here so I will include it should anybody be in my situation.
My situation, I have a remote repository of maybe 10,000 files and I need to build an RPM file for my Linux system. The build of the RPM includes a git clone of everything. All I need is one file to start the RPM build. I can clone the entire source tree which does what I need but it takes an extra two minutes to download all those files when all I need is one. I tried to use the git archive option discussed and I got “fatal: Operation not supported by protocol.” It seems I have to get some sort of archive option enabled on the server and my server is maintained by bureaucratic thugs that seem to enjoy making it difficult to get things done.
What I finally did was I went into the web interface for bitbucket and viewed the one file I needed. I did a right click on the link to download a raw copy of the file and selected “copy shortcut” from the resulting popup. I could not just download the raw file because I needed to automate things and I don’t have a browser interface on my Linux server.
For the sake of discussion, that resulted in the URL:
https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest
I could not directly download this file from the bitbucket repository because I needed to sign in first. After a little digging, I found this worked: On Linux:
echo "myUser:myPass123"| base64
bXlVc2VyOm15UGFzczEyMwo=
curl -H 'Authorization: Basic bXlVc2VyOm15UGFzczEyMwo=' 'https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest' > bar.spec
This combination allowed me to download the one file I needed to build everything else.
Install "xclip" if you haven't...
sudo apt-get install xclip
Xclip puts the data into the "selection/highlighted" clipboard that you middle-click to paste as opposed to "ctrl+v"
While in vim use ex commands:
7w !xclip
or
1,7w !xclip
or
%w !xclip
Then just middle-click to paste into any other application...
This is array initializer syntax, and it can only be used on the right-hand-side when declaring a variable of array type. Example:
int[] x = {1,2,3,4};
String y = {"a","b","c"};
If you're not on the RHS of a variable declaration, use an array constructor instead:
int[] x;
x = new int[]{1,2,3,4};
String y;
y = new String[]{"a","b","c"};
These declarations have the exact same effect: a new array is allocated and constructed with the specified contents.
In your case, it might actually be clearer (less repetitive, but a bit less concise) to specify the table programmatically:
double[][] m = new double[4][4];
for(int i=0; i<4; i++) {
for(int j=0; j<4; j++) {
m[i][j] = i*j;
}
}
The following line will start reading a number (%d
) followed by anything different from tabs or newlines (%[^\t\n]
).
sscanf("19 cool kid", "%d %[^\t\n]", &age, buffer);
I've written a very simple router abstraction on top of History.js, called StateRouter.js. It's in very early stages of development, but I am using it as the routing solution in a single-page application I'm writing. Like you, I found History.js very hard to grasp, especially as I'm quite new to JavaScript, until I understood that you really need (or should have) a routing abstraction on top of it, as it solves a low-level problem.
This simple example code should demonstrate how it's used:
var router = new staterouter.Router();
// Configure routes
router
.route('/', getHome)
.route('/persons', getPersons)
.route('/persons/:id', getPerson);
// Perform routing of the current state
router.perform();
Here's a little fiddle I've concocted in order to demonstrate its usage.
The body hasn't been defined at this point yet. In general, you want to create all elements before you execute javascript that uses these elements. In this case you have some javascript in the head
section that uses body
. Not cool.
You want to wrap this code in a window.onload
handler or place it after the <body>
tag (as mentioned by e-bacho 2.0).
<head>
<title>Javascript Tests</title>
<script type="text/javascript">
window.onload = function() {
var mySpan = document.createElement("span");
mySpan.innerHTML = "This is my span!";
mySpan.style.color = "red";
document.body.appendChild(mySpan);
alert("Why does the span change after this alert? Not before?");
}
</script>
</head>
I'd like to throw an additional option into the mix that doesn't require a formula but might be helpful if you need to count unique values within the set across two different columns. Using the original example, I didn't have:
ABC 123
ABC 123
ABC 123
DEF 456
DEF 567
DEF 456
DEF 456
and want it to appear as:
ABC 1
DEF 2
But something more like:
ABC 123
ABC 123
ABC 123
ABC 456
DEF 123
DEF 456
DEF 567
DEF 456
DEF 456
and wanted it to appear as:
ABC
123 3
456 1
DEF
123 1
456 3
567 1
I found the best way to get my data into this format and then be able to manipulate it further was to use the following:
Once you select 'Running total in' then choose the header for the secondary data set (in this case it would be the header or column title of the data set that includes 123, 456 and 567). This will give you a max value with the total count of items in that set, within your primary data set.
I then copied this data, pasted it as values, then put it in another pivot table to manipulate it more easily.
FYI, I had about a quarter million rows of data so this worked a lot better than some of the formula approaches, especially ones that try to compare across two columns/data sets because it kept crashing the application.
Just change "target": "es2015" to "target": "es5" in your tsconfig.json.

Both will works perfectly in mysqli_fetch_array in while loops
while($row = mysqli_fetch_array($result,MYSQLI_BOTH)) {
$posts[] = $row['post_id'].$row['post_title'].$row['content'];
}
(OR)
while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) {
$posts[] = $row['post_id'].$row['post_title'].$row['content'];
}
mysqli_fetch_array() - has second argument $resulttype.
MYSQLI_ASSOC: Fetch associative array
MYSQLI_NUM: Fetch numeric array
MYSQLI_BOTH: Fetch both associative and numeric array.
You could also try the following to add an inline style to the element:
$(this).attr('style', 'text-align: center');
This should make sure that other styling rules aren't overriding what you thought would work. I believe inline styles usually get precedence.
EDIT: Also, another tool that may help you is Jash (http://www.billyreisinger.com/jash/). It gives you a javascript command prompt so you can ensure you easily test javascript statements and make sure you're selecting the right element, etc.
I'm pretty late to the party, but here is another implementation using ng-bootstrap: https://stackblitz.com/edit/angular-confirmation-dialog
confirmation-dialog.service.ts
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';
import { ConfirmationDialogComponent } from './confirmation-dialog.component';
@Injectable()
export class ConfirmationDialogService {
constructor(private modalService: NgbModal) { }
public confirm(
title: string,
message: string,
btnOkText: string = 'OK',
btnCancelText: string = 'Cancel',
dialogSize: 'sm'|'lg' = 'sm'): Promise<boolean> {
const modalRef = this.modalService.open(ConfirmationDialogComponent, { size: dialogSize });
modalRef.componentInstance.title = title;
modalRef.componentInstance.message = message;
modalRef.componentInstance.btnOkText = btnOkText;
modalRef.componentInstance.btnCancelText = btnCancelText;
return modalRef.result;
}
}
confirmation-dialog.component.ts
import { Component, Input, OnInit } from '@angular/core';
import { NgbActiveModal } from '@ng-bootstrap/ng-bootstrap';
@Component({
selector: 'app-confirmation-dialog',
templateUrl: './confirmation-dialog.component.html',
styleUrls: ['./confirmation-dialog.component.scss'],
})
export class ConfirmationDialogComponent implements OnInit {
@Input() title: string;
@Input() message: string;
@Input() btnOkText: string;
@Input() btnCancelText: string;
constructor(private activeModal: NgbActiveModal) { }
ngOnInit() {
}
public decline() {
this.activeModal.close(false);
}
public accept() {
this.activeModal.close(true);
}
public dismiss() {
this.activeModal.dismiss();
}
}
confirmation-dialog.component.html
<div class="modal-header">
<h4 class="modal-title">{{ title }}</h4>
<button type="button" class="close" aria-label="Close" (click)="dismiss()">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
{{ message }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" (click)="decline()">{{ btnCancelText }}</button>
<button type="button" class="btn btn-primary" (click)="accept()">{{ btnOkText }}</button>
</div>
Use the dialog like this:
public openConfirmationDialog() {
this.confirmationDialogService.confirm('Please confirm..', 'Do you really want to ... ?')
.then((confirmed) => console.log('User confirmed:', confirmed))
.catch(() => console.log('User dismissed the dialog (e.g., by using ESC, clicking the cross icon, or clicking outside the dialog)'));
}
I am a novice and I did it this way:
Create table Name1
(
F_Name varchar(20),
L_Name varchar(20),
Age INTEGER
)
Insert into Name1
Values
('Tom', 'Bombadil', 32),
('Danny', 'Fartman', 43),
('Stephine', 'Belchlord', 33),
('Corry', 'Smallpants', 95)
Go
Update Name1
Set F_Name = CONCAT(F_Name, ' ', L_Name)
Go
Alter Table Name1
Drop column L_Name
Go
Update Table_Name
Set F_Name
You can use the DateTime
class:
$past = new DateTime("2010-01-01 00:00:00");
$now = new DateTime();
$future = new DateTime("2021-01-01 00:00:00");
Comparison operators work*:
var_dump($past < $now); // bool(true)
var_dump($future < $now); // bool(false)
var_dump($now == $past); // bool(false)
var_dump($now == new DateTime()); // bool(true)
var_dump($now == $future); // bool(false)
var_dump($past > $now); // bool(false)
var_dump($future > $now); // bool(true)
It is also possible to grab the timestamp values from DateTime objects and compare them:
var_dump($past ->getTimestamp()); // int(1262286000)
var_dump($now ->getTimestamp()); // int(1431686228)
var_dump($future->getTimestamp()); // int(1577818800)
var_dump($past ->getTimestamp() < $now->getTimestamp()); // bool(true)
var_dump($future->getTimestamp() > $now->getTimestamp()); // bool(true)
* Note that ===
returns false when comparing two different DateTime objects even when they represent the same date.
Here's what I do:
<?php echo date("d-m-Y") ?>
below is a bit of explanation of what it does:
d = day
m = month
Y = year
Y will gives you four digit (e.g. 1990) and y for two digit (e.g. 90)
For the <tr>
's just set
tr {
line-height: 25px;
min-height: 25px;
height: 25px;
}
It works with bootstrap also. For the 100%
height, 100%
must be 100% of something. Therefore, you must define a fixed height for one of the containers, or the body. I guess you want the entire page to be 100%, so (example) :
body {
height: 700px;
}
.table100, .row, .container, .table-responsive, .table-bordered {
height: 100%;
}
A workaround not to set a static height is by forcing the height in code according to the viewport :
$('body').height(document.documentElement.clientHeight);
all the above in this fiddle -> http://jsfiddle.net/LZuJt/
Note : I do not care that you have 25%
height on #description
, and 100%
height on table. Guess it is just an example. And notice that clientHeight
is not right since the documentElement is an iframe, but you'll get the picture in your own projekt :)
I'm not sure if this works for you, but when I do small solo PHP projects with Eclipse, the first thing I set up is an Ant script for deploying the project to a remote testing environment. I code away locally, and whenever I want to test it, I just hit the shortcut which updates the remote site.
Eclipse has good Ant support out of the box, and the scripts aren't hard to make.
Here's your problem:
int latitude = (int) (location.getLatitude());
int longitude = (int) (location.getLongitude());
Latitude and Longitude are double
-values, because they represent the location in degrees.
By casting them to int
, you're discarding everything behind the comma, which makes a big difference. See "Decimal Degrees - Wiki"
Probably it's too late to answer but a couple things since this is a really annoying error. Following solution worked on Mac OS X Yosemite.
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
The include with fast cgi params should go above that line.
All your directories down to the PHP file you're executing (including that file too) should have a+x
permissions, e.g.
sudo chmod a+x /Users/ sudo chmod a+x /Users/oleg/ sudo chmod a+x /Users/oleg/www/ sudo chmod a+x /Users/oleg/www/a.php
One hint about the "background-size: cover" solution, you have to put it after "background" definition, otherwise it won't work, for example this won't work:
html, body {
height: 100%;
background-size: cover;
background:url("http://i.imgur.com/aZO5Kolb.jpg") no-repeat center center fixed;
}
With this code you can obtain any controller:
var controller = DependencyResolver.Current.GetService<ControllerB>();
controller.ControllerContext = new ControllerContext(this.Request.RequestContext,
controller);
That corresponds to the long (or Int64), a 64-bit integer.
Although if the number from the database happens to be small enough, and you accidentally use an Int32, etc., you'll be fine. But the Int64 will definitely hold it.
And the error you get if you use something smaller and the full size is needed? A stack overflow! Yay!
I'd try the following steps:
1) Check if there is a Byte Order Mark
2) Check if the file is valid UTF8
3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)
Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8.
As the PHP.net manual suggests, take a read of this discussion.
One major difference is that echo
can take multiple parameters to output. E.g.:
echo 'foo', 'bar'; // Concatenates the 2 strings
print('foo', 'bar'); // Fatal error
If you're looking to evaluate the outcome of an output statement (as below) use print
. If not, use echo
.
$res = print('test');
var_dump($res); //bool(true)
I wanted to convert a string to a double. This above answer didn't quite work for me. But this did: How to do string conversions in Objective-C?
All I pretty much did was:
double myDouble = [myString doubleValue];
I've never seen this error before, but whenever I can't get Xcode and React-Native to play well together, I do a couple of things. Check what version of Xcode I'm working with. If it needs to be updated, I update it. Then clearing watchman and the cache are the second place I go. I don't use the reset cache command. It always says that I need to verify the cache, so I skip that (you can do it though, I just get confused). I use rm -rf $TMPDIR/react-* to get rid of any cached builds. If that doesn't work, I try to build the app in Xcode, then work my way from there, to build it with react-native run-ios. With this error message, it seems you might start by trying to build it with Xcode. Hope that helps...let me know your progress with it. Good luck! (Also, you could update to RN 0.51 as another attempt to get your versions synced.)
Also, if you don't have the gradlew file in your current directory:
You can install gradle with homebrew with the following command:
$ brew install gradle
As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):
$ gradle test
You can use parseInt(jQuery.offset().top)
to always use the Integer (primitive - int
) value across all browsers.
HttpClient was deprecated in API Level 22 and removed in API Level 23.
You have to use URLConnection
.
this short code worked for me:
Configuration wConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);
ClientSection wClientSection = wServiceSection.Client;
wClientSection.Endpoints[0].Address = <your address>;
wConfig.Save();
Of course you have to create the ServiceClient proxy AFTER the config has changed. You also need to reference the System.Configuration and System.ServiceModel assemblies to make this work.
Cheers
While you can alias your tables within your query (i.e., "SELECT u.username FROM users u;"), you have to use the actual names of the columns you're referencing. AS only impacts how the fields are returned.
The easiest way is to invite @get_id_bot in your chat and then type:
/my_id @get_id_bot
Inside your chat
You can try this before using job_titles
string:
source = unicode(job_titles, 'utf-8')
I know its late but it might be helpful for those that want other ways. Another way array key=>values can be stored is by using an array method called map(); (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) you can use arrow function too
var countries = ['Canada','Us','France','Italy'];
// Arrow Function
countries.map((value, key) => key+ ' : ' + value );
// Anonomous Function
countries.map(function(value, key){
return key + " : " + value;
});
You can add a filter for the nav_menu_css_class
action in your functions.php file.
Example:
function atg_menu_classes($classes, $item, $args) {
if($args->theme_location == 'secondary') {
$classes[] = 'list-inline-item';
}
return $classes;
}
add_filter('nav_menu_css_class', 'atg_menu_classes', 1, 3);

This thread is a bit older, but thought I'd post what I currently do (work in progress).
Though I'm still hitting situations where the system is under heavy load and when I click a submit button (e.g., login.jsp), all three conditions (see below) return true
but the next page (e.g., home.jsp) hasn't started loading yet.
This is a generic wait method that takes a list of ExpectedConditions.
public boolean waitForPageLoad(int waitTimeInSec, ExpectedCondition<Boolean>... conditions) {
boolean isLoaded = false;
Wait<WebDriver> wait = new FluentWait<>(driver)
.withTimeout(waitTimeInSec, TimeUnit.SECONDS)
.ignoring(StaleElementReferenceException.class)
.pollingEvery(2, TimeUnit.SECONDS);
for (ExpectedCondition<Boolean> condition : conditions) {
isLoaded = wait.until(condition);
if (isLoaded == false) {
//Stop checking on first condition returning false.
break;
}
}
return isLoaded;
}
I have defined various reusable ExpectedConditions (three are below). In this example, the three expected conditions include document.readyState = 'complete', no "wait_dialog" present, and no 'spinners' (elements indicating async data is being requested).
Only the first one can be generically applied to all web pages.
/**
* Returns 'true' if the value of the 'window.document.readyState' via
* JavaScript is 'complete'
*/
public static final ExpectedCondition<Boolean> EXPECT_DOC_READY_STATE = new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
String script = "if (typeof window != 'undefined' && window.document) { return window.document.readyState; } else { return 'notready'; }";
Boolean result;
try {
result = ((JavascriptExecutor) driver).executeScript(script).equals("complete");
} catch (Exception ex) {
result = Boolean.FALSE;
}
return result;
}
};
/**
* Returns 'true' if there is no 'wait_dialog' element present on the page.
*/
public static final ExpectedCondition<Boolean> EXPECT_NOT_WAITING = new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
Boolean loaded = true;
try {
WebElement wait = driver.findElement(By.id("F"));
if (wait.isDisplayed()) {
loaded = false;
}
} catch (StaleElementReferenceException serex) {
loaded = false;
} catch (NoSuchElementException nseex) {
loaded = true;
} catch (Exception ex) {
loaded = false;
System.out.println("EXPECTED_NOT_WAITING: UNEXPECTED EXCEPTION: " + ex.getMessage());
}
return loaded;
}
};
/**
* Returns true if there are no elements with the 'spinner' class name.
*/
public static final ExpectedCondition<Boolean> EXPECT_NO_SPINNERS = new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
Boolean loaded = true;
try {
List<WebElement> spinners = driver.findElements(By.className("spinner"));
for (WebElement spinner : spinners) {
if (spinner.isDisplayed()) {
loaded = false;
break;
}
}
}catch (Exception ex) {
loaded = false;
}
return loaded;
}

Depending on the page, I may use one or all of them:
waitForPageLoad(timeoutInSec,
EXPECT_DOC_READY_STATE,

I think that your JAVA_HOME should point to
C:\Program Files\Java\jdk1.6.0_25
instead of
C:\Program Files\Java\jdk1.6.0_25\bin
That is, without the bin folder.
UPDATE
That new error appears to me if I set the JAVA_HOME with the quotes, like you did. Are you using quotation marks? If so, remove them.
Remove last 3 characters of a string
var str = '1437203995000';
str = str.substring(0, str.length-3);
// '1437203995'
Remove last 3 digits of a number
var a = 1437203995000;
a = (a-(a%1000))/1000;
// a = 1437203995
Your tables should have as immediate children just tbody
and thead
elements, with the rows within*. So, amend the HTML to be:
<table border="1" width="100%" id="test">
<tbody>
<tr>
<td>
<table border="1" width="100%">
<tbody>
<tr>
<td>table 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
</tbody>
</table>
Then amend your selector slightly to this:
#test > tbody > tr:last-child { background:#ff0000; }
See it in action here. That makes use of the child selector, which:
...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.
So, you are targeting only direct children of tbody
elements that are themselves direct children of your #test
table.
The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:
#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }
* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:
...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.
First, open Device Manager by searching for it in the Windows search bar.
Then, click ports and right click the port the Arduino is connected to. Then, go to Port settings → Advanced. Next, select any port that is not in use and is not the port the Arduino is currently connected to. Then click OK and unplug + replug your Arduino. This works most of the time with any Arduino board.
Very rarely would you want an empty string if the value is 0.
decimal test = 5.00;
test.ToString("0.00"); //"5.00"
decimal? test2 = 5.05;
test2.ToString("0.00"); //"5.05"
decimal? test3 = 0;
test3.ToString("0.00"); //"0.00"
The top rated answer is incorrect and has wasted 10 minutes of (most) people's time.
Yeild
keyword in javaScript function makes it generator,
what is generator in javaScript?
A generator is a function that produces a sequence of results instead of a single value, i.e you generate ?a series of values
Meaning generators helps us work asynchronously with the help iterators, Oh now what the hack iterators are? really?
Iterators are mean through which we are able to access items one at a time
from where iterator help us accessing item one at a time? it help us accessing items through generator functions,
generator functions are those in which we use yeild
keyword, yield keyword help us in pausing and resuming execution of function
here is quick example
function *getMeDrink() {
let question1 = yield 'soda or beer' // execution will pause here because of yield
if (question1 == 'soda') {
return 'here you get your soda'
}
if (question1 == 'beer') {
let question2 = yield 'Whats your age' // execution will pause here because of yield
if (question2 > 18) {
return "ok you are eligible for it"
} else {
return 'Shhhh!!!!'
}
}
}
let _getMeDrink = getMeDrink() // initialize it
_getMeDrink.next().value // "soda or beer"
_getMeDrink.next('beer').value // "Whats your age"
_getMeDrink.next('20').value // "ok you are eligible for it"
_getMeDrink.next().value // undefined
let me brifly explain what is going on
you noticed execution is being paused at each yeild
keyword
and we are able to access first yield
with help of iterator .next()
this iterates to all yield
keywords one at a time and then returns undefined when there is no more yield
keywords left
in simple words you can say yield
keyword is break point where function each time pauses and only resume when call it using iterator
for our case: _getMeDrink.next()
this is example of iterator that is helping us accessing each break point in function
Example of Generators:
async/await
if you see implementation of async/await
you will see generator functions & promises
are used to make async/await
work
please point out any suggestions is welcomed
You simply forgot to supply an argument to -i
. Just change -i
to -i ''
.
Of course that means you don't want your files to be backed up; otherwise supply your extension of choice, like -i .bak
.
Use ImageView
... it have transparent background by default...
Let's assume you want to overwrite the same file:
import json
with open('data.json', 'r') as data_file:
data = json.load(data_file)
for element in data:
element.pop('hours', None)
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
dict.pop(<key>, not_found=None)
is probably what you where looking for, if I understood your requirements. Because it will remove the hours
key if present and will not fail if not present.
However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?
Now, if you really want to use del
instead of pop
, here is how you could make your code work:
import json
with open('data.json') as data_file:
data = json.load(data_file)
for element in data:
if 'hours' in element:
del element['hours']
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.
I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.
with
is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with
block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.
Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.
I hope it's clear enough...
SECOND EDIT
This time, it seems clear that you need to do this:
with open('dest_file.json', 'w') as dest_file:
with open('source_file.json', 'r') as source_file:
for line in source_file:
element = json.loads(line.strip())
if 'hours' in element:
del element['hours']
dest_file.write(json.dumps(element))
$file_parts = pathinfo($filename);
$file_parts['extension'];
$cool_extensions = Array('jpg','png');
if (in_array($file_parts['extension'], $cool_extensions)){
FUNCTION1
} else {
FUNCTION2
}
SELECT Lname, Cods, CASE WHEN Lname LIKE '% HN%' THEN SUBSTRING(Lname,
CHARINDEX(' ', Lname) - 50, 50) WHEN Lname LIKE 'HN%' THEN Lname ELSE
Lname END AS LnameTrue FROM dbo.____Fname_Lname
Turns out that YUI's reset CSS strips the list style from 'ul li' instead of just 'ul', which is why setting it just in 'ul' never worked.
I'm using
Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"
to format a column
So I guess
Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"
would do the trick for you.

If you are set on using EXISTS you can use the below in SQL Server:
SELECT * FROM TableB as b
WHERE NOT EXISTS
(
SELECT * FROM TableA as a
WHERE b.id = a.id
)
In your case, you presumably don't want to use grep, but add instead a negative clause to the find command, e.g.
find /home/baumerf/public_html/ -mmin -60 -not -name error_log
If you want to include wildcards in the name, you'll have to escape them, e.g. to exclude files with suffix .log:
find /home/baumerf/public_html/ -mmin -60 -not -name \*.log
Another great option is the free V-Tools addin for Microsoft Access. Among other helpful tools it has a form to edit and save the Import/Export specifications.
Note: As of version 1.83, there is a bug in enumerating the code pages on Windows 10. (Apparently due to a missing/changed API function in Windows 10) The tools still works great, you just need to comment out a few lines of code or step past it in the debug window.
This has been a real life-saver for me in editing a complex import spec for our online orders.
seems ok... though I'd think a rudimentary indication of success/failure/time posted/# bytes received/etc. would be preferable.
edit: I was thinking along the lines of data integrity and/or record-keeping; metadata such as an MD5 hash or timestamp for time received may be helpful for large datafiles.
