the main issue with the following error:
no drawer view found with absolute gravity LEFT
is that, you defined the
android:layout_gravity="right"
for list-view in right, but try to open the drawer from left, by calling this function:
mDrawerToggle.syncState();
and clicking on hamburger icon!
just comment the above function and try to handle open/close of menu like @Rudi said!
Because input
's width
is controlled by it's size
attribute, this is how I initialize an input
width
according to its content:
<input type="text" class="form-list-item-name" [size]="myInput.value.length" #myInput>
Environment variables (that you modify using the System Properties) are only propagated to subshells when you create a new subshell.
If you had a command line prompt (DOS or cygwin) open when you changed the User env vars, then they won't show up.
You need to open a new command line prompt after you change the user settings.
The equivalent in Unix/Linux is adding a line to your .bash_rc: you need to start a new shell to get the values.
To accomplish this, add 2 CSS properties on the <body>
element.
body {
height: 100%;
overflow-y: hidden;
}
These days there are many news websites which require users to create an account. Typically they will give full access to the page for about a second, and then they show a pop-up, and stop users from scrolling down.
As you can see, 01/01/1970 returns 0, which means it is the lowest possible date.
new Date('1970-01-01Z00:00:00:000') //returns Thu Jan 01 1970 01:00:00 GMT+0100 (Central European Standard Time)
new Date('1970-01-01Z00:00:00:000').getTime() //returns 0
new Date('1970-01-01Z00:00:00:001').getTime() //returns 1
Without other external class you can create your personal hack code simply using
event.keyCode
Another help for all, I think is this test page for intercept the keyCode (simply copy and past in new file.html for testing your event).

You can use .change()
$('input[name=myInput]').change(function() { ... });
However, this event will only fire when the selector has lost focus, so you will need to click somewhere else to have this work.
If that's not quite right for you, you could use some of the other jQuery events like keyup, keydown or keypress - depending on the exact effect you want.
I upvoted Kooilnc's solution. Really nice compact solution. There's one small edge case that I would like to address. If someone enters a really long character sequence for whatever reason, it won't get truncated:
function truncate(str, n, useWordBoundary) {
var singular, tooLong = str.length > n;
useWordBoundary = useWordBoundary || true;
// Edge case where someone enters a ridiculously long string.
str = tooLong ? str.substr(0, n-1) : str;
singular = (str.search(/\s/) === -1) ? true : false;
if(!singular) {
str = useWordBoundary && tooLong ? str.substr(0, str.lastIndexOf(' ')) : str;
}
return tooLong ? str + '…' : str;
}
What I suggest you do is add a META-INF
directory with a MANIFEST.MF
file in .war file.
Please note that according to servlet spec, it must be a .war file and not .war directory for the META-INF/MANIFEST.MF
to be read by container.
Edit the MANIFEST.MF
Class-Path property to C:\app_config\java_app
:
See Using JAR Files: The Basics (Understanding the Manifest)
Enjoy.
Super (or inherited) is Very Good Thing because if you need to stick another inheritance layer in between Base and Derived, you only have to change two things: 1. the "class Base: foo" and 2. the typedef
If I recall correctly, the C++ Standards committee was considering adding a keyword for this... until Michael Tiemann pointed out that this typedef trick works.
As for multiple inheritance, since it's under programmer control you can do whatever you want: maybe super1 and super2, or whatever.
I faced the same problem, like mentioned above I tried these.
This is what worked for me:
flutter doctor --android-licenses
and select y
for the promptsflutter doctor
and everything will be fine!!!!I recommend that not to use checkBox.setOnCheckedChangeListener
in recyclerViewAdapter
. Because on scrolling recyclerView, checkBox.setOnCheckedChangeListener
will be fired by adapter. It's not safe. Instead, use checkBox.setOnClickListener
to interact with user inputs.
For example:
public void onBindViewHolder(final ViewHolder holder, int position) {
/*
.
.
.
.
.
.
*/
holder.checkBoxAdapterTasks.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
boolean isChecked = holder.checkBoxAdapterTasks.isChecked();
if(isChecked){
//checkBox clicked and checked
}else{
//checkBox clicked and unchecked
}
}
});
}
You have to move the css
folder into your web
folder. It seems that your web
folder on the hard drive equals the /ServletApp
folder as seen from the www. Other content than inside your web
folder cannot be accessed from the browsers.
The url of the CSS link is then
<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
You have to define public String toString()
method in your Student
class. For example:
public String toString() {
return "Student: " + studentName + ", " + studentNo;
}
To a file:
require 'csv'
CSV.open("myfile.csv", "w") do |csv|
csv << ["row", "of", "CSV", "data"]
csv << ["another", "row"]
# ...
end
To a string:
require 'csv'
csv_string = CSV.generate do |csv|
csv << ["row", "of", "CSV", "data"]
csv << ["another", "row"]
# ...
end
Here's the current documentation on CSV: http://ruby-doc.org/stdlib/libdoc/csv/rdoc/index.html
Use DateTime with DateTime::format()
$datetime = new DateTime($dateTimeString);
echo $datetime->format('w');
Better alternative also created by me is here: https://stackoverflow.com/a/23692008/2829600 (supports "delete functions")
I wrote this simple function for handling delay in execution, useful inside jQuery .scroll() and .resize() So callback_f will run only once for specific id string.
function delay_exec( id, wait_time, callback_f ){
// IF WAIT TIME IS NOT ENTERED IN FUNCTION CALL,
// SET IT TO DEFAULT VALUE: 0.5 SECOND
if( typeof wait_time === "undefined" )
wait_time = 500;
// CREATE GLOBAL ARRAY(IF ITS NOT ALREADY CREATED)
// WHERE WE STORE CURRENTLY RUNNING setTimeout() FUNCTION FOR THIS ID
if( typeof window['delay_exec'] === "undefined" )
window['delay_exec'] = [];
// RESET CURRENTLY RUNNING setTimeout() FUNCTION FOR THIS ID,
// SO IN THAT WAY WE ARE SURE THAT callback_f WILL RUN ONLY ONE TIME
// ( ON LATEST CALL ON delay_exec FUNCTION WITH SAME ID )
if( typeof window['delay_exec'][id] !== "undefined" )
clearTimeout( window['delay_exec'][id] );
// SET NEW TIMEOUT AND EXECUTE callback_f WHEN wait_time EXPIRES,
// BUT ONLY IF THERE ISNT ANY MORE FUTURE CALLS ( IN wait_time PERIOD )
// TO delay_exec FUNCTION WITH SAME ID AS CURRENT ONE
window['delay_exec'][id] = setTimeout( callback_f , wait_time );
}
// USAGE
jQuery(window).resize(function() {
delay_exec('test1', 1000, function(){
console.log('1st call to delay "test1" successfully executed!');
});
delay_exec('test1', 1000, function(){
console.log('2nd call to delay "test1" successfully executed!');
});
delay_exec('test1', 1000, function(){
console.log('3rd call to delay "test1" successfully executed!');
});
delay_exec('test2', 1000, function(){
console.log('1st call to delay "test2" successfully executed!');
});
delay_exec('test3', 1000, function(){
console.log('1st call to delay "test3" successfully executed!');
});
});
/* RESULT
3rd call to delay "test1" successfully executed!
1st call to delay "test2" successfully executed!
1st call to delay "test3" successfully executed!
*/
Text inside an ifdef/endif
or ifndef/endif
pair will be left in or removed by the pre-processor depending on the condition. ifdef
means "if the following is defined" while ifndef
means "if the following is not defined".
So:
#define one 0
#ifdef one
printf("one is defined ");
#endif
#ifndef one
printf("one is not defined ");
#endif
is equivalent to:
printf("one is defined ");
since one
is defined so the ifdef
is true and the ifndef
is false. It doesn't matter what it's defined as. A similar (better in my opinion) piece of code to that would be:
#define one 0
#ifdef one
printf("one is defined ");
#else
printf("one is not defined ");
#endif
since that specifies the intent more clearly in this particular situation.
In your particular case, the text after the ifdef
is not removed since one
is defined. The text after the ifndef
is removed for the same reason. There will need to be two closing endif
lines at some point and the first will cause lines to start being included again, as follows:
#define one 0
+--- #ifdef one
| printf("one is defined "); // Everything in here is included.
| +- #ifndef one
| | printf("one is not defined "); // Everything in here is excluded.
| | :
| +- #endif
| : // Everything in here is included again.
+--- #endif
Create modal dialog in HTML with id="confirmation" and use function showConfirmation.
Also remember you should to unbind (modal.unbind()) cancel and success buttons after hide modal dialog. If you do not make this you will get double binding. For example: if you open dialog once and press 'Cancel' and then open dialog in second time and press 'Ok' you will get 2 executions of success callback.
showConfirmation = function(title, message, success, cancel) {
title = title ? title : 'Are you sure?';
var modal = $("#confirmation");
modal.find(".modal-title").html(title).end()
.find(".modal-body").html(message).end()
.modal({ backdrop: 'static', keyboard: false })
.on('hidden.bs.modal', function () {
modal.unbind();
});
if (success) {
modal.one('click', '.modal-footer .btn-primary', success);
}
if (cancel) {
modal.one('click', '.modal-header .close, .modal-footer .btn-default', cancel);
}
};
// bind confirmation dialog on delete buttons
$(document).on("click", ".delete-event, .delete-all-event", function(event){
event.preventDefault();
var self = $(this);
var url = $(this).data('url');
var success = function(){
alert('window.location.href=url');
}
var cancel = function(){
alert('Cancel');
};
if (self.data('confirmation')) {
var title = self.data('confirmation-title') ? self.data('confirmation-title') : undefined;
var message = self.data('confirmation');
showConfirmation(title, message, success, cancel);
} else {
success();
}
});
You could do this by styling an "x"
text-align: center;
font-size: 120px;
line-height: 100px;
color: white;
font-family: monospace;
Off the top of my head:
Array
* - represents an old-school memory array - kind of like a alias for a normal type[]
array. Can enumerate. Can't grow automatically. I would assume very fast insert and retrival speed.
ArrayList
- automatically growing array. Adds more overhead. Can enum., probably slower than a normal array but still pretty fast. These are used a lot in .NET
List
- one of my favs - can be used with generics, so you can have a strongly typed array, e.g. List<string>
. Other than that, acts very much like ArrayList
Hashtable
- plain old hashtable. O(1) to O(n) worst case. Can enumerate the value and keys properties, and do key/val pairs
Dictionary
- same as above only strongly typed via generics, such as Dictionary<string, string>
SortedList
- a sorted generic list. Slowed on insertion since it has to figure out where to put things. Can enum., probably the same on retrieval since it doesn't have to resort, but deletion will be slower than a plain old list.
I tend to use List
and Dictionary
all the time - once you start using them strongly typed with generics, its really hard to go back to the standard non-generic ones.
There are lots of other data structures too - there's KeyValuePair
which you can use to do some interesting things, there's a SortedDictionary
which can be useful as well.
Well one way to do it is set the height of your body to the height
that you want your page
to be. In this example I did 600px
.
Then set your wrapper
height to a percentage of the body here I did 70%
This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.
body {
padding-top: 70px;
border:1px solid black;
height:600px;
}
.mygrid-wrapper-div {
border: solid red 5px;
overflow: scroll;
height: 70%;
}
Update How about a jQuery approach.
$(function() {
var window_height = $(window).height(),
content_height = window_height - 200;
$('.mygrid-wrapper-div').height(content_height);
});
$( window ).resize(function() {
var window_height = $(window).height(),
content_height = window_height - 200;
$('.mygrid-wrapper-div').height(content_height);
});
"Spaces" in the original post could refer to whitespace, and no answer yet shows how to remove ALL whitespace from a string. For that regular expressions are the most flexible approach I've found.
Below is a console application where you can see the difference between replacing just spaces or all whitespace.
You can find more about .NET regular expressions at http://msdn.microsoft.com/en-us/library/hs600312.aspx and http://msdn.microsoft.com/en-us/library/az24scfc.aspx
Imports System.Text.RegularExpressions
Module TestRegExp
Sub Main()
' Use to match all whitespace (note the lowercase s matters)
Dim regWhitespace As New Regex("\s")
' Use to match space characters only
Dim regSpace As New Regex(" ")
Dim testString As String = "First Line" + vbCrLf + _
"Second line followed by 2 tabs" + vbTab + vbTab + _
"End of tabs"
Console.WriteLine("Test string :")
Console.WriteLine(testString)
Console.WriteLine("Replace all whitespace :")
' This prints the string on one line with no spacing at all
Console.WriteLine(regWhitespace.Replace(testString, String.Empty))
Console.WriteLine("Replace all spaces :")
' This removes spaces, but retains the tabs and new lines
Console.WriteLine(regSpace.Replace(testString, String.Empty))
Console.WriteLine("Press any key to finish")
Console.ReadKey()
End Sub
End Module
I don't think emulator and simulator can be compared. Both mimic something, but are not part of the same scope of reasonning, they are not used in the same context.
In short: an emulator is designed to copy some features of the orginial and can even replace it in the real environment. A simulator is not desgined to copy the features of the original, but only to appear similar to the original to human beings. Without the features of the orginal, the simulator cannot replace it in the real environment.
An emulator is a device that mimics something close enough so that it can be substituted to the real thing. E.g you want a circuit to work like a ROM (read only memory) circuit, but also wants to adjust the content until it is what you want. You'll use a ROM emulator, a black box (likely to be CPU-based) with a physical and electrical interfaces compatible with the ROM you want to emulate. The emulator will be plugged into the device in place of the real ROM. The motherboard will not see any difference when working, but you will be able to change the emulated-ROM content easily. Said otherwise the emulator will act exactly as the actual thing in its motherboard context (maybe a little bit slower due to actual internal model) but there will be additional functions (like re-writing) visible only to the designer, out of the motherboard context. So emulator definition would be: something that mimic the original, has all of its functional features, can actually replace it to some extend in the real world, and may have additional features not visible in the normal context.
A simulator is used in another thinking context, e.g a plane simulator, a car simulator, etc. The simulation will take care only of some aspect of the actual thing, usually those related to how a human being will perceive and control it. The simulator will not perform the functions of the real stuff, and cannot be sustituted to it. The plane simulator will not fly or carry someone, it's not its purpose at all. The simulator is not intended to work, but to appear to the pilot somehow like the actual thing for purposes other than its normal ones, e.g. to allow ground training (including in unusual situations like all-engine failure). So simulator definition would be: something that can appear to human, to some extend, like the original, but cannot replace it for actual use. In addition the pilot will know that the simulator is a simulator.
I don't think we'll see any ROM simulator, because ROM are not interacting with human beings, nor we'll see any plane emulator, because planes cannot have a replacement performing the same functions in the real world.
In my view the model inside an emulator or a simulator can be anything, and has not to be similar to the model of the original. A ROM emulator model will likely be software instead of hardware, MS Flight Simulator cannot be more software than it is.
This comparison of both terms will contradict the currently selected answer (from Toybuilder) which puts the difference on the internal model, while my suggestion is that the difference is whether the fake can or cannot be used to perform the actual function in the actual world (to some accepted extend, indeed).
Note that the plane simulator will have also to simulate the earth, the sun, the wind, etc, which are not part of the plane, so a plane simulator will have to mimic some aspects of the plane, as well as the environment of the plane because it is not used in this actual environment, but in a training room.
This is a big difference with the emulator which emulates only the orginal, and its purpose is to be used in the environment of the original with no need to emulate it. Back to the plane context... what could be a plane emulator? Maybe a train that will connect two airports -- actually two plane steps -- carrying passengers, with stewardesses onboard, with car interior looking like an actual plane cabin, and with captain saying "ladies and gentlemen our altitude is currenlty 10 kms and the temperature at our destination is 24°C". Its benefit is difficult to see, hum...
As a conclusion, the emulator is a real thing intended to work, the simulator is a fake intended to trick the user.
An utility method like the following can be used to solve this.
import (
"os"
"path/filepath"
"log"
)
func ensureDir(fileName string) {
dirName := filepath.Dir(fileName)
if _, serr := os.Stat(dirName); serr != nil {
merr := os.MkdirAll(dirName, os.ModePerm)
if merr != nil {
panic(merr)
}
}
}
func main() {
_, cerr := os.Create("a/b/c/d.txt")
if cerr != nil {
log.Fatal("error creating a/b/c", cerr)
}
log.Println("created file in a sub-directory.")
}
Now with new JavaScript version (ECMAScript 6 http://es6-features.org/#ClassDefinition) there is a better way to submit requests using nodejs and Promise request (http://www.wintellect.com/devcenter/nstieglitz/5-great-features-in-es6-harmony)
Using library: https://github.com/request/request-promise
npm install --save request
npm install --save request-promise
client:
//Sequential execution for node.js using ES6 ECMAScript
var rp = require('request-promise');
rp({
method: 'POST',
uri: 'http://localhost:3000/',
body: {
val1 : 1,
val2 : 2
},
json: true // Automatically stringifies the body to JSON
}).then(function (parsedBody) {
console.log(parsedBody);
// POST succeeded...
})
.catch(function (err) {
console.log(parsedBody);
// POST failed...
});
server:
var express = require('express')
, bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.json());
app.post('/', function(request, response){
console.log(request.body); // your JSON
var jsonRequest = request.body;
var jsonResponse = {};
jsonResponse.result = jsonRequest.val1 + jsonRequest.val2;
response.send(jsonResponse);
});
app.listen(3000);
I use this function for my projects:
public static String minuteToTime(int minute) {
int hour = minute / 60;
minute %= 60;
String p = "AM";
if (hour >= 12) {
hour %= 12;
p = "PM";
}
if (hour == 0) {
hour = 12;
}
return (hour < 10 ? "0" + hour : hour) + ":" + (minute < 10 ? "0" + minute : minute) + " " + p;
}
Another solution would be the usage of std::make_move_iterator to build a new vector (C++11 )
int main(){
std::map<std::string, int> map;
//Populate map
std::vector<std::pair<std::string, int>> v {std::make_move_iterator(begin(map)),
std::make_move_iterator(end(map))};
// Create a vector with the map parameters
sort(begin(v), end(v),
[](auto p1, auto p2){return p1.second > p2.second;});
// Using sort + lambda function to return an ordered vector
// in respect to the int value that is now the 2nd parameter
// of our newly created vector v
}
Class : A class is a blue print. Object : It is the copy of the class. Instance : Its a variable which is used to hold memory address of the object.
A very basic analytical example
Class House --> Blueprint of the house. But you can't live in the blue print. You need a physical House which is the instance of the class to live in. i.e., actual address of the object is instance. Instances represent objects.
You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:
<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>
</body>
</html>
Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.
Based on the excellent DateTimeSpan work done above, I've normalized the code a bit; this seems to work pretty well:
public class DateTimeSpan
{
private DateTimeSpan() { }
private DateTimeSpan(int years, int months, int days, int hours, int minutes, int seconds, int milliseconds)
{
Years = years;
Months = months;
Days = days;
Hours = hours;
Minutes = minutes;
Seconds = seconds;
Milliseconds = milliseconds;
}
public int Years { get; private set; } = 0;
public int Months { get; private set; } = 0;
public int Days { get; private set; } = 0;
public int Hours { get; private set; } = 0;
public int Minutes { get; private set; } = 0;
public int Seconds { get; private set; } = 0;
public int Milliseconds { get; private set; } = 0;
public static DateTimeSpan CompareDates(DateTime StartDate, DateTime EndDate)
{
if (StartDate.Equals(EndDate)) return new DateTimeSpan();
DateTimeSpan R = new DateTimeSpan();
bool Later;
if (Later = StartDate > EndDate)
{
DateTime D = StartDate;
StartDate = EndDate;
EndDate = D;

This error occurs because the transaction log becomes full due to LOG_BACKUP. Therefore, you can’t perform any action on this database, and In this case, the SQL Server Database Engine will raise a 9002 error.
To solve this issue you should do the following
I wrote an article with all details regarding this error and how to solve it at The transaction log for database ‘SharePoint_Config’ is full due to LOG_BACKUP

Here is a jQuery plugin which will return an array of all the classes the matched element(s) have
;!(function ($) {
$.fn.classes = function (callback) {
var classes = [];
$.each(this, function (i, v) {
var splitClassName = v.className.split(/\s+/);
for (var j = 0; j < splitClassName.length; j++) {
var className = splitClassName[j];
if (-1 === classes.indexOf(className)) {
classes.push(className);
}
}
});
if ('function' === typeof callback) {
for (var i in classes) {
callback(classes[i]);
}
}
return classes;
};
})(jQuery);
Use it like
$('div').classes();
In your case returns
["Lorem", "ipsum", "dolor_spec", "sit", "amet"]
You can also pass a function to the method to be called on each class
$('div').classes(
function(c) {
// do something with each class
}
);
Here is a jsFiddle I set up to demonstrate and test http://jsfiddle.net/GD8Qn/8/
;!function(e){e.fn.classes=function(t){var n=[];e.each(this,function(e,t){var r=t.className.split(/\s+/);for(var i in r){var s=r[i];if(-1===n.indexOf(s)){n.push(s)}}});if("function"===typeof t){for(var r in n){t(n[r])}}return n}}(jQuery);

Many of the answers here were valid until recently. For now, the ONLY supported param is url
, and the new share link is as follows...
https://www.linkedin.com/sharing/share-offsite/?url={url}
Make sure url
is encoded, using something like fixedEncodeURIComponent()
.
Source: Official Microsoft.com Linkedin Share Plugin Documentation. All LinkedIn.com links for developer documentation appear to be blank pages now -- perhaps related to the acquisition of LinkedIn by Microsoft.
Once upon a time, you could use these params: title
, summary
, source
. But if you look closely at all of the documentation, there is actually still a way to still set summary, title, etc.! Put these in the <head>
block of the page you want to share...
<meta property='og:title' content='Title of the article"/>
<meta property='og:image' content='//media.example.com/ 1234567.jpg"/>
<meta property='og:description' content='Description that will show in the preview"/>
<meta property='og:url' content='//www.example.com/URL of the article" />
Then LinkedIn will use these! Source: LinkedIn Developer Docs: Making Your Website Shareable on LinkedIn.
Not sure you did everything right? Take the URL of the page you are sharing (i.e., example.com, not linkedin.com/share?url=example.com), and input that URL into the following: LinkedIn Post Inspector. This will tell you everything about how your URL is being shared!
This also pulls/invalidates the current cache of your page, and then refreshes it (in case you have a stuck, cached version of your page in LinkedIn's database). Because it pulls the cache, then refreshes it, sometimes it's best to use the LinkedIn Post Inspector twice, and use the second result as the expected output.
Still not sure? Here's an online demo I built with 20+ social share services. Inspect the source code and find out for yourself how exactly the LinkedIn sharing is working.
I have been maintaining a Github Repo that's been tracking social-share URL formats since 2012, check it out: Github: Social Share URLs.
Why not join in on all the social share url's?
You are looking for the cp
command. You need to change directories so that you are outside of the directory you are trying to copy.
If the directory you're copying is called dir1
and you want to copy it to your /home/Pictures
folder:
cp -r dir1/ ~/Pictures/
Linux is case-sensitive and also needs the /
after each directory to know that it isn't a file. ~
is a special character in the terminal that automatically evaluates to the current user's home directory. If you need to know what directory you are in, use the command pwd
.
When you don't know how to use a Linux command, there is a manual page that you can refer to by typing:
man [insert command here]
at a terminal prompt.
Also, to auto complete long file paths when typing in the terminal, you can hit Tab after you've started typing the path and you will either be presented with choices, or it will insert the remaining part of the path.
If you want to split the string, it's best to use:
$array = str_split($string);
When you have delimiter, which separates the string, you can try,
explode('' ,$string);
Where you can pass the delimiter in the first variable inside the explode such as:
explode(',',$string);
You can do it in one sql statement for existing customers, 3 statements for new ones. All you have to do is be an optimist and act as though the customer already exists:
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);
If the customer does not exist, you'll get an sql exception which text will be something like:
null value in column "customer_id" violates not-null constraint
(providing you made customer_id non-nullable, which I'm sure you did). When that exception occurs, insert the customer into the customer table and redo the insert into the order table:
insert into customer(name) values ('John');
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);
Unless your business is growing at a rate that will make "where to put all the money" your only real problem, most of your inserts will be for existing customers. So, most of the time, the exception won't occur and you'll be done in one statement.
What solved the problem for me was going to: "Run"->"Attach Debugger to Android process" and then select your process.
You do this in Android Studio.
It's much easier to just use jQuery, since this is just a task for university and you do not need to save code.
So, your code will look like:
function sendMyComment() {
$('#addComment').append('<input type="hidden" name="video_id" id="video_id" value="' + $('#video_id').text() + '"/><input type="hidden" name="video_time" id="video_time" value="' + $('#time').text() +'"/>');
$.ajax({
type: 'POST',
url: $('#addComment').attr('action'),
data: $('form').serialize(),
success: function(response) { ... },
});
}
Beyond historical (good and already reported) reasons, there's is also a little problem with operators precedence: dot operator has higher priority than star operator, so if you have struct containing pointer to struct containing pointer to struct... These two are equivalent:
(*(*(*a).b).c).d
a->b->c->d
But the second is clearly more readable. Arrow operator has the highest priority (just as dot) and associates left to right. I think this is clearer than use dot operator both for pointers to struct and struct, because we know the type from the expression without have to look at the declaration, that could even be in another file.
I wanted to run npm install from within my external hard drive as this is where i saved my code workspace. Windows 10 OS.

Have you tried setting a namespace declaration to your member variables like this? :
@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;
@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;
For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.
Or you could use dsquery and dsget:

The documentation libraries phpdoc and Doxygen perform a kind of code analysis. Doxygen, for example, can be configured to render nice inheritance graphs with Graphviz.
Another option is xhprof, which is similar to Xdebug, but lighter, making it suitable for production servers. The tool includes a PHP-based interface.

@Vaiden answer helped me. I couldn't understand why short lists can raise this exceptions. I have many fragments and a couple of ViewPager
s with lists. So, every time I started another activity or stopped a program (turned off a screen) I catched this exception (usually on Xiaomi).
I found that all fragments called their onSaveInstanceState()
events, and in the end hosting activity called onSaveInstanceState()
before onStop()
. After that a crash occured. So, I understood that many short lists (10-100 Kb in size) can raise TransactionTooLargeException
exception.
You may overcome this problem with writing data to a database and then get items by their id
s. This way you can pass a list of id
s to an Activity/Fragment.
But if you wish a temporary fast method, do this.
1) Create a retain-instance fragment, that will survive during activity recreation.
class SavedInstanceFragment : Fragment() {
// This map will hold bundles from different sources (tag -> bundle).
private lateinit var bundleMap: HashMap<String, Bundle?>
// This method is only called once for this fragment.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
retainInstance = true
bundleMap = HashMap()
}
fun pushData(key: String, bundle: Bundle): SavedInstanceFragment {
if (bundleMap[key] == null) {
bundleMap[key] = bundle
} else {
bundleMap[key]!!.putAll(bundle)
}
return this
}
fun popData(key: String): Bundle? {
val data = bundleMap[key]
bundleMap[key] = null
return data
}
fun removeData(key: String) {
bundleMap.remove(key)
}
companion object {
private val TAG = SavedInstanceFragment::class.java.simpleName
// Create the fragment with this method in `onCreate()` of an activity.
// Then you can get this fragment with this method again.
fun getInstance(fragmentManager: FragmentManager): SavedInstanceFragment {
var out = fragmentManager.findFragmentByTag(TAG) as SavedInstanceFragment?
if (out == null) {
out = SavedInstanceFragment()
fragmentManager.beginTransaction().add(out, TAG).commit()
}
return out
}
}
}
2) In onCreate()
of your activities that hold problem fragments, create this fragment. It will survive activity recreations. You should create it before other fragments are added to the FragmentManager
, because this operation is asynchronous.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity)
if (savedInstanceState == null) {
SavedInstanceFragment.getInstance(supportFragmentManager)
}
...
}
3) In every problem fragment add these lines. You should access a retain-instance fragment with getInstance(activity!!.supportFragmentManager)
everywhere, so that you can find it inside FragmentManager
. If use childFragmentManager
as a parameter of getInstance()
, then you will create another fragment and crash.
Also clear arguments
after you read them and set a bundle
, for instance, in onSaveInstanceState
: arguments?.clear()
. This is very important because arguments stay in memory when you create a new fragment. When you later return to the current fragment and rotate a screen, data won't be lost because they are already contained in a bundle
and will be read in onCreate
.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val bundle = if (savedInstanceState == null) {
// Remove old data in order not to show wrong information.
SavedInstanceFragment.getInstance(activity!!.supportFragmentManager).removeData(TAG)
null
} else {
SavedInstanceFragment.getInstance(activity!!.supportFragmentManager).popData(TAG)
}
(bundle ?: arguments)?.run { // I access 'bundle' or 'arguments', depending if it is not first or first call of 'onCreate()'.
token = getString(ARG_TOKEN)!!
id = getInt(ARG_ID)
items = getParcelableArrayList(ARG_ITEMS)
}
}
override fun onSaveInstanceState(outState: Bundle) {
// Create a copy of savedInstanceState and push to the retain-instance fragment.
val bundle = (outState.clone() as Bundle).apply {
putString(ARG_TOKEN, token)
putInt(ARG_ID, id)
putParcelableArrayList(ARG_ITEMS, items)
}
SavedInstanceFragment.getInstance(activity!!.supportFragmentManager).pushData(TAG, bundle)
arguments?.clear() // Avoids an exception "java.lang.RuntimeException: android.os.TransactionTooLargeException: data parcel size xxxxxxx bytes".
super.onSaveInstanceState(outState)
}
companion object {
private val TAG = YourFragment::class.java.simpleName
private const val ARG_TOKEN = "ARG_TOKEN"
private const val ARG_ID = "ARG_ID"
private const val ARG_ITEMS = "ARG_ITEMS"
fun newInstance(token: String, id: Int, items: ArrayList<Item>?) =
YourFragment().apply {
arguments = Bundle().apply {
putString(ARG_TOKEN, token)
putInt(ARG_ID, id)
putParcelableArrayList(ARG_ITEMS, items)
}
}
}
Instead of persistent fragment you can use Singleton. Also read https://medium.com/@mdmasudparvez/android-os-transactiontoolargeexception-on-nougat-solved-3b6e30597345 for more information about libraries, solutions.
I suppose, this solution won't work if your activities are removed after starting other activities. You can check this behaviour when turn on a checkbox Do not keep activities
in Developer options (don't forget to uncheck after). In this case getFragmentManager()
will be new and you won't get old data. When you return from the new activity, you will get null
in a bundle
.
You could use an fstream
and open it with the std::ios::app
flag. Have a look at the code below and it should clear your head.
...
fstream f("filename.ext", f.out | f.app);
f << "any";
f << "text";
f << "written";
f << "wll";
f << "be append";
...
You can find more information about the open modes here and about fstreams here.

list = []

Note that you generally should not shadow reserved function names, such as list

or list_
instead, for instance.
Use find:

On systems that use GNU find, like most GNU/Linux distributions, you can leave out the -print.
You'll have to resort to XHTML or HTML 4.01 for this. Although iframe

Change the order of statments. For me, changing the block of code
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/context
http://www.springframework.org/schema/beans/spring-beans.xsd"
with
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context"
is valid.
The file location/path has to relative to your classpath locations. If resources directory is in your classpath you just need "app-context.xml" as file location.

A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision.
IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).
A Double
in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double
object.
You can list cookies for current domain:
function listCookies() {
var theCookies = document.cookie.split(';');
var aString = '';
for (var i = 1 ; i <= theCookies.length; i++) {
aString += i + ' ' + theCookies[i-1] + "\n";
}
return aString;
}
But you cannot list cookies for other domains for security reasons
When page is load then scroll is max value .
This is message box when user send message then always show latest chat in down so that scroll value is always is maxium.
$('#message').scrollTop($('#message')[0].scrollHeight);
If Template is not set (i.e. ==null), this error will be raised, too.
More comments:
If you know the parameter value by the time you add parameters, you can also use AddWithValue
The EXEC is not required. You can reference the @template parameter in the SELECT directly.
You do not need to take a pointer to the array in order to pass it to an array-generating function, because arrays already decay to pointers when you pass them to functions. Simply make the parameter int a[]
, and use it as a regular array inside the function, the changes will be made to the array that you have passed in.
void generateArray(int a[], int si) {
srand(time(0));
for (int j=0;j<*si;j++)
a[j]=(0+rand()%9);
}
int main(){
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
As a side note, you do not need to pass the size by pointer, because you are not changing it inside the function. Moreover, it is not a good idea to pass a pointer to constant to a parameter that expects a pointer to non-constant.
You are using this :
mysql_fetch_array($result)
To get the error you're getting, it means that $result
is not a resource.
In your code, $result
is obtained this way :
$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
If the SQL query fails, $result
will not be a resource, but a boolean -- see mysql_query
.
I suppose there's an error in your SQL query -- so it fails, mysql_query
returns a boolean, and not a resource, and mysql_fetch_array
cannot work on that.
You should check if the SQL query returns a result or not :
$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
if ($result !== false) {
// use $result
} else {
// an error has occured
echo mysql_error();
die; // note : echoing the error message and dying
// is OK while developping, but not in production !
}
With that, you should get a message that indicates the error that occured while executing your query -- this should help figure out what the problem is ;-)
Also, you should escape the data you're putting in your SQL query, to avoid SQL injections !
For example, here, you should make sure that $_GET['id']
contains nothing else than an integer, using something like this :
$result = mysql_query("SELECT * FROM student WHERE IDNO=" . intval($_GET['id']));
Or you should check this before trying to execute the query, to display a nicer error message to the user.
Unfortunately, not in the .Net BCL. Dates are usually represented as a DateTime object with the time set to midnight.
As you can guess, this means that you have all the attendant timezone issues around it, even though for a Date object you'd want absolutely no timezone handling.
With Mercurial you do a
$ hg grep "search for this" [file...]
There are other options that narrow down the range of revisions that are searched.
Your code looks correct. My suggestion is that the database already thinks it's upgraded. If you executed the project after incrementing the version number, but before adding the execSQL
call, the database on your test device/emulator may already believe it's at version 2.
A quick way to verify this would be to change the version number to 3 -- if it upgrades after that, you know it was just because your device believed it was already upgraded.

From Tomcat Documentation
maxConnections When this number has been reached, the server will accept, but not process, one further connection. once the limit has been reached, the operating system may still accept connections based on the acceptCount setting. (The maximum queue length for incoming connection requests when all possible request processing threads are in use. Any requests received when the queue is full will be refused. The default value is 100.) For BIO the default is the value of maxThreads unless an Executor is used in which case the default will be the value of maxThreads from the executor. For NIO and NIO2 the default is 10000. For APR/native, the default is 8192. Note that for APR/native on Windows, the configured value will be reduced to the highest multiple of 1024 that is less than or equal to maxConnections. This is done for performance reasons.
maxThreads
The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool.
First of all, I suggest to modify a bit your sql query:
select * from shift
where shift.shiftid not in (select employeeshift.shiftid from employeeshift
where employeeshift.empid = 57);
This query provides same functionality. If you want to get the same result with LINQ, you can try this code:
//Variable dc has DataContext type here
//Here we get list of ShiftIDs from employeeshift table
List<int> empShiftIds = dc.employeeshift.Where(p => p.EmpID = 57).Select(s => s.ShiftID).ToList();
//Here we get the list of our shifts
List<shift> shifts = dc.shift.Where(p => !empShiftIds.Contains(p.ShiftId)).ToList();
In addition if one uses static keyword on a variable like this example:
namespace {
static int flag;
}
It would not be seen in the mapping file
Bind the button, this is done with jQuery:
$("#my-table input[type='button']").click(function(){
var parameter = $(this).val();
window.location = "http://yoursite.com/page?variable=" + parameter;
});
This search engine was made to solve exactly the kind of problem you're having: http://symbolhound.com/
I am the developer of SymbolHound.
This solution caters for http, https and the other normal url type special characters :
import re
def remove_urls (vTEXT):
vTEXT = re.sub(r'(https|http)?:\/\/(\w|\.|\/|\?|\=|\&|\%)*\b', '', vTEXT, flags=re.MULTILINE)
return(vTEXT)
print( remove_urls("this is a test https://sdfs.sdfsdf.com/sdfsdf/sdfsdf/sd/sdfsdfs?bob=%20tree&jef=man lets see this too https://sdfsdf.fdf.com/sdf/f end"))
You can bypass just to run the view, SQL will wine and cry but just do this and run it! You can't save.
create or replace view v_emp(eno number) as select * from emp where (emp_id = @Parameter1);
Based on your requirement i think you are wanted to put dynamic fields in CSS file, however that is not possible as CSS is a static language. However you can simulate the behaviour by using Angular.

That being said - are you sure you want to be updating the values to be +1 each time? Couldn't you just find the count and then set the values based on that?
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 :)
The best option I found and the less intrusive, is to set a tag param in your xml, like
PHONE XML LAYOUT
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="phone"/>
TABLET XML LAYOUT
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="tablet">
...
</RelativeLayout>
and then call this in your activity class:
View viewPager = findViewById(R.id.pager);
Log.d(getClass().getSimpleName(), String.valueOf(viewPager.getTag()));
Hope it works for u.
One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files
Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:
SELECT name, salary
FROM employees
order by salary desc limit 1,1
and this query should do your job.
First we are sorting the table in descending way so the person with the highest salary is at the top, and the second highest is at the second position. Now limit a,b
means skip the starting a
elements and then print the next b
elements. So you should use limit 1,1
in this case.
Hope this helps.
For end of line use:
git diff --ignore-space-at-eol
Instead of what are you using currently:
git diff -w (--ignore-all-space)
For start of line... you are out of luck if you want a built in solution.
However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".
Default is:
Username: root
Password: [null]
The Password is set to 'password' in some versions.
Haha, I have been stuck at that point a while ago as well, so I am glad I can help you out with a solution, that worked for me at least :)
What you want to do is define a new style within values/styles.xml so it looks like this
<resources>
<style name = "AppTheme" parent = "android:Theme.Holo.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<style name = "NoActionBar" parent = "@android:style/Theme.Holo.Light">
<item name = "android:windowActionBar">false</item>
<item name = "android:windowNoTitle">true</item>
</style>
</resources>
Only the NoActionBar style is intresting for you. At last you have to set is as your application's theme in the AndroidManifest.xml so it looks like this
<application
android:allowBackup = "true"
android:icon = "@drawable/ic_launcher"
android:label = "@string/app_name"
android:theme = "@style/NoActionBar" <!--This is the important line-->
>
<activity
[...]
I hope this helps, if not, let me know.
In response to others:
You don't need to specify case in BASH4 just use the ',,' to make a var lowercase. Also I strongly dislike putting code inside of the read block, get the result and deal with it outside of the read block IMO. Also include a 'q' for quit IMO. Lastly why type 'yes' just use -n1 and have the press y.
Example: user can press y/n and also q to just quit.
ans=''
while true; do
read -p "So is MikeQ the greatest or what (y/n/q) ?" -n1 ans
case ${ans,,} in
y|n|q) break;;
*) echo "Answer y for yes / n for no or q for quit.";;
esac
done
echo -e "\nAnswer = $ans"
if [[ "${ans,,}" == "q" ]] ; then
echo "OK Quitting, we will assume that he is"
exit 0
fi
if [[ "${ans,,}" == "y" ]] ; then
echo "MikeQ is the greatest!!"
else
echo "No? MikeQ is not the greatest?"
fi
Here is a function that will do it without jQuery:
function getElementOffset(element)
{
var de = document.documentElement;
var box = element.getBoundingClientRect();
var top = box.top + window.pageYOffset - de.clientTop;
var left = box.left + window.pageXOffset - de.clientLeft;
return { top: top, left: left };
}
I cannot comment Palehorse's answer so I added my own answer. Palehorse's logic is ok but efficiency can be bad with big data sets.
DELETE FROM some_child_table sct
WHERE exists (SELECT FROM some_Table st
WHERE sct.some_fk_fiel=st.some_id);
DELETE FROM some_table;
It is faster if you have indexes on columns and data set is bigger than few records.
The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.
For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.
1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication
I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.
The accepted answer does not work for databases that have large numbers of tables, e.g. Drupal databases. Instead, see the script here: https://stackoverflow.com/a/12917793/1507877 which does work on MySQL 5.5. CAUTION: Around line 11, there is a "WHERE table_schema = SCHEMA();" This should instead be "WHERE table_schema = 'INSERT NAME OF DB INTO WHICH IMPORT WILL OCCUR';"
It just simply means that the value for column project_id
on table comments
you are inserting doesn't exist on table projects
. Bear in mind that the values of column project_id
on table comments
is dependent on the values of ID
on table Projects
.
The value 50dc845a-83e4-4db3-8705-5432ae7aaee3
you are inserting for column project_id
does not exist on table projects
.
you can 'invoke' alternative bindings on Y
this way:
...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).
Note the parenthesis are required to keep the correct execution control flow. The ;
/2 it's the general or
operator. For your restricted use you could as well choice the more idiomatic
...registered(X, Y), member(Y, [ct101,ct102,ct103]).
that on backtracking binds Y to each member of the list.
edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead
...registered(X, ct101), registered(X, ct102), registered(X, ct103).
or the more compact
...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).
findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.
...setof(Y, registered(X, Y), [ct101,ct102,ct103]).
setof/3 also sorts the result list
Change to directory with correct java.exe
i.e. go to the required JDK version java.exe

They say it right there in the documentation for the FPDF constructor:
FPDF([string orientation [, string unit [, mixed size]]])
This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes). Parameters ...
size
The size used for pages. It can be either one of the following values (case insensitive):
A3 A4 A5 Letter Legal
or an array containing the width and the height (expressed in the unit given by unit).
They even give an example with custom size:
Example with a custom 100x150 mm page size:
$pdf = new FPDF('P','mm',array(100,150));
If you are sure id.substring(indexPos) is a number, you can do it like so:
var number = Number(id.substring(indexPos)) + 1;
Otherwise I suggest checking if the Number function evaluates correctly.
These instructions explain how to install a python2 and python3 kernel in separate virtual environments for non-anaconda users. If you are using anaconda, please find my other answer for a solution directly tailored to anaconda.
I assume that you already have jupyter notebook
installed.
First make sure that you have a python2
and a python3
interpreter with pip
available.
On ubuntu you would install these by:
sudo apt-get install python-dev python3-dev python-pip python3-pip
Next prepare and register the kernel environments
python -m pip install virtualenv --user
# configure python2 kernel
python -m virtualenv -p python2 ~/py2_kernel
source ~/py2_kernel/bin/activate
python -m pip install ipykernel
ipython kernel install --name py2 --user
deactivate
# configure python3 kernel
python -m virtualenv -p python3 ~/py3_kernel
source ~/py3_kernel/bin/activate
python -m pip install ipykernel
ipython kernel install --name py3 --user
deactivate
To make things easier, you may want to add shell aliases for the activation command to your shell config file. Depending on the system and shell you use, this can be e.g. ~/.bashrc
, ~/.bash_profile
or ~/.zshrc
alias kernel2='source ~/py2_kernel/bin/activate'
alias kernel3='source ~/py3_kernel/bin/activate'
After restarting your shell, you can now install new packages after activating the environment you want to use.
kernel2
python -m pip install <pkg-name>
deactivate
or
kernel3
python -m pip install <pkg-name>
deactivate
Definitely using the Url property is the way to go. Whether to set it in the app.config, the database, or a third location sort of depends on your configuration needs. Sometimes you don't want the app to restart when you change the web service location. You might not have a load balancer scaling the backend. You might be hot-patching a web service bug. Your implementation might have security configuration issues as well. Whether it's production db usernames and passwords or even the ws security auth info. The proper separation of duties can get you into some more involved configuration setups.
If you add a wrapper class around the proxy generated classes, you can set the Url property in some unified fashion every time you create the wrapper class to call a web method.
There's no need to contact the repository to get the name, and the folder name won't necessarily reflect the remote name.
I've found this to be the most accurate and efficient way to get the current repository name:
basename -s .git `git config --get remote.origin.url`
This should work as of Git 1.8.1.5. Prior to this, the now deprecated git-repo-config
command would have worked (as early as Git 1.7.5).
I found it in /Users//Library/Android/sdk
As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().
Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static
for the example. Once it's done, add this line in your server code:
app.use("/static", express.static('./static/'));
This will effectively serve every file in your "static" folder via the /static route.
Querying your index.js file in the client thus becomes:
<script src="static/index.js"></script>
<input type="text" ng-keypress="checkNumeric($event)"/>
//inside controller
$scope.dot = false
$scope.checkNumeric = function($event){
if(String.fromCharCode($event.keyCode) == "." && !$scope.dot){
$scope.dot = true
}
else if( isNaN(String.fromCharCode($event.keyCode))){
$event.preventDefault();
}
See ipdata.co a service I built that is fast and has reliable performance thanks to having 10 global endpoints each able to handle >10,000 requests per second!
This answer uses a 'test' API Key that is very limited and only meant for testing a few calls. Signup for your own Free API Key and get up to 1500 requests daily for development.
This snippet will return the details of your current ip. To lookup other ip addresses, simply append the ip to the https://api.ipdata.co?api-key=test url eg.
https://api.ipdata.co/1.1.1.1?api-key=test
The API also provides an is_eu
field indicating whether the user is in an EU country.
$.get("https://api.ipdata.co?api-key=test", function (response) {_x000D_
$("#response").html(JSON.stringify(response, null, 4));_x000D_
}, "jsonp");
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

Here's the fiddle; https://jsfiddle.net/ipdata/6wtf0q4g/922/
I also wrote this detailed analysis of 8 of the best IP Geolocation APIs.
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
One common use is for template-typedef workaround classes like following:
template <class TObj>
class MyLibrariesSmartPointer
{
MyLibrariesSmartPointer();
public:
typedef smart_ptr<TObj> type;
};
Obviously a public non-implemented constructor would work aswell, but a private construtor raises a compile time error instead of a link time error, if anyone tries to instatiate MyLibrariesSmartPointer<SomeType>
instead of MyLibrariesSmartPointer<SomeType>::type
, which is desireable.
You can either use
<h:outputText value="#{param['id']}" />
or
<h:outputText value="#{request.getParameter('id')}" />
However if you want to pass the parameters to your backing beans, using f:viewParam
is probably what you want. "A view parameter is a mapping between a query string parameter and a model value."
<f:viewParam name="id" value="#{blog.entryId}"/>
This will set the id param of the GET parameter to the blog bean's entryId
field. See http://java.dzone.com/articles/bookmarkability-jsf-2 for the details.

Ok, per pix0r's, Sparks' and Dave's answers it looks like there are three ways to do this:
NameVirtualHost *:80
).Add your virtual host (~line 36):
<VirtualHost *:80>
DocumentRoot C:\Projects\transitCalculator\trunk
ServerName transitcalculator.localhost
<Directory C:\Projects\transitCalculator\trunk>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
Open your hosts file (C:\Windows\System32\drivers\etc\hosts).
Add
127.0.0.1 transitcalculator.localhost #transitCalculator
to the end of the file (before the Spybot - Search & Destroy stuff if you have that installed).
Now you can access that directory by browsing to http://transitcalculator.localhost/.
Starting ~line 200 of your http.conf
file, copy everything between <Directory "C:/xampp/htdocs">
and </Directory>
(~line 232) and paste it immediately below with C:/xampp/htdocs
replaced with your desired directory (in this case C:/Projects
) to give your server the correct permissions for the new directory.
Find the <IfModule alias_module></IfModule>
section (~line 300) and add
Alias /transitCalculator "C:/Projects/transitCalculator/trunk"
(or whatever is relevant to your desires) below the Alias
comment block, inside the module tags.
Edit ~line 176 in C:\xampp\apache\conf\httpd.conf; change DocumentRoot "C:/xampp/htdocs"
to #DocumentRoot "C:/Projects"
(or whatever you want).
Edit ~line 203 to match your new location (in this case C:/Projects
).
Notes:
Short answer: Don't do it.
Longer answer: Use WCF. It's here to replace Asmx.
see this answer for example, or the first comment on this one.
John Saunders: ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.
As for comment ... well, if you have to, you have to. I'll leave you in the competent hands of the other answers then. (Even though it's funny it has issues, and if it does, why are you doing it in VS2013 to begin with ?)
A very practical reason is that IE 6 doesn't let you resize the font if it's specified using px, whereas it does if you use a relative unit such as em or percentages. Not allowing the user to resize the font is very bad for accessibility. Although it's in decline, there are still a lot of IE 6 users out there.
You can use pydash:
import pydash as _
_.get(dataDict, ["b", "v", "y"], default='Default')
Already mentioned. Just a LINQ answer:
var columns = reader.GetSchemaTable().Rows
.Cast<DataRow>()
.Select(r => (string)r["ColumnName"])
.ToList();
//Or
var columns = Enumerable.Range(0, reader.FieldCount)
.Select(reader.GetName)
.ToList();
The second one is cleaner and much faster. Even if you cache GetSchemaTable
in the first approach, the querying is going to be very slow.
One solution that I've found is that you should have to change the .Net Framework back to v2.0 by Right Clicking on the site that you have manager under the Application Pools from the Advance Settings.
If return no correct AUTO_INCREMENT, try it:
ANALYZE TABLE `my_table`;
SELECT AUTO_INCREMENT FROM information_schema.TABLES WHERE (TABLE_NAME = 'my_table');

Only way to dynamically attach a property is to create a new class and its instance with your new property.

Don't forget to change 16.12.0 to the latest version or the version you need to setup.
To check that the file you're trying to open actually exists, you can change directories in terminal using cd
. To change to ~/Desktop/sass/css
: cd ~/Desktop/sass/css
. To see what files are in the directory: ls
.
If you want information about either of those commands, use the man
page: man cd
or man ls
, for example.
Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.
On Mac OS X, you can also use open
to open a finder window: open .
will open the current directory in finder. (open ~/Desktop/sass/css
will open the ~/Desktop/sass/css
).
Under linux, the simpler is:
find
to do a recursive search of *.java files wc -l
to count lines:To resume, just do:
find . -name '*.java' | xargs wc -l
To be certain that a folder exists (and not a file) I use this function:
Public Function FolderExists(strFolderPath As String) As Boolean
On Error Resume Next
FolderExists = ((GetAttr(strFolderPath) And vbDirectory) = vbDirectory)
On Error GoTo 0
End Function
It works both, with \
at the end and without.
Added this answer because none of other available above worked for me.
In my case something even more weird was happening (Django 1.7 Version), In my models.py I had an "extra" line at the end of my file (it was a blank line) and when I executed the python manage.py makemigrations
command the result was: "no changes detected".
To fix this I deleted this "blank line" that was at the end of my models.py file and I did run the command again, everything was fixed and all the changes made to models.py were detected!
Suppose you want to store the result of an echo command
echo hello
x=$(echo hello)
echo "$x",world!
output:
hello
hello,world!
A SELECT INTO
statement creates the table for you. There is no need for the CREATE TABLE
statement before hand.
What is happening is that you create #ivmy_cash_temp1
in your CREATE
statement, then the DB tries to create it for you when you do a SELECT INTO
. This causes an error as it is trying to create a table that you have already created.
Either eliminate the CREATE TABLE
statement or alter your query that fills it to use INSERT INTO SELECT
format.
If you need a unique ID added to your new row then it's best to use SELECT INTO
... since IDENTITY()
only works with this syntax.
I couldn't used android:anyDensity="true" because objects in my game would be positioned completely different... seems this also does the trick:
// creating locale Locale locale2 = new Locale(loc); Locale.setDefault(locale2); Configuration config2 = new Configuration(); config2.locale = locale2; // updating locale mContext.getResources().updateConfiguration(config2, null);
The following will return NULL if the array is empty, else the last element.
var item = (arr.Length == 0) ? null : arr[arr.Length - 1]
This error can happen if you have two jars that contains the same class names, e.g. I had two library: jsr311-api-1.1.1.jar, and jersey-core-1.17.1.jar, both containing the class javax.ws.rs.ApplicationPath. I removed jsr311-api-1.1.1.jar and it worked fine.
The topic is quite old, yet I struggled with the same issue today while compiling cegui 0.7.1 (openVibe prerequisite).
What worked for me was to set: LDFLAGS="-Wl,--no-as-needed"

for LDFLAGS
but to no avail.
@Michael Yagudaev 's answer works for me.
But the original answer did not chain the wrapped promise with .catch() to handle reject handling, here is my improvement on top of @Michael Yagudaev's answer:
const makeCancelablePromise = promise => {
let hasCanceled = false;
const wrappedPromise = new Promise((resolve, reject) => {
promise
.then(val => (hasCanceled ? reject({ isCanceled: true }) : resolve(val)))
.catch(
error => (hasCanceled ? reject({ isCanceled: true }) : reject(error))
);
});
return {
promise: wrappedPromise,
cancel() {
hasCanceled = true;
}
};
};
// Example Usage:
const cancelablePromise = makeCancelable(
new Promise((rs, rj) => {
/*do something*/
})
);
cancelablePromise.promise.then(() => console.log('resolved')).catch(err => {
if (err.isCanceled) {
console.log('Wrapped promise canceled');
return;
}
console.log('Promise was not canceled but rejected due to errors: ', err);
});
cancelablePromise.cancel();
Of the options you asked about:
float:left;
float
concept was poorly designed in the CSS specs. Nothing we can do about that now though. But the important thing is it does work, and it works in all browsers (even IE6/7), so use it if you like it.The additional markup for clearing may not be necessary if you use the :after
selector to clear the floats, but this isn't an option if you want to support IE6 or IE7.
display:inline;
This shouldn't be used for layout, with the exception of IE6/7, where display:inline; zoom:1
is a fall-back hack for the broken support for inline-block
.
display:inline-block;
This is my favourite option. It works well and consistently across all browsers, with a caveat for IE6/7, which support it for some elements. But see above for the hacky solution to work around this.
The other big caveat with inline-block
is that because of the inline aspect, the white spaces between elements are treated the same as white spaces between words of text, so you can get gaps appearing between elements. There are work-arounds to this, but none of them are ideal. (the best is simply to not have any spaces between the elements)
display:table-cell;
table-cell
is designed to be used in a context of being inside elements that are styled as table
and table-row
; using table-cell
in isolation is not the intended way to do it, so you may experience different browsers treating it differently.Other techniques you may have missed? Yes.
Since you say this is for a multi-column layout, there is a CSS Columns feature that you might want to know about. However it isn't the most well supported feature (not supported by IE even in IE9, and a vendor prefix required by all other browsers), so you may not want to use it. But it is another option, and you did ask.
There's also CSS FlexBox feature, which is intended to allow you to have text flowing from box to box. It's an exciting feature that will allow some complex layouts, but this is still very much in development -- see http://html5please.com/#flexbox
Hope that helps.
Add this function in your file -
Color parseColor(String color) {
String hex = color.replaceAll("#", "");
if (hex.isEmpty) hex = "ffffff";
if (hex.length == 3) {
hex = '${hex.substring(0, 1)}${hex.substring(0, 1)}${hex.substring(1, 2)}${hex.substring(1, 2)}${hex.substring(2, 3)}${hex.substring(2, 3)}';
}
Color col = Color(int.parse(hex, radix: 16)).withOpacity(1.0);
return col;
}
And use it like -
Container(
color: parseColor("#b74093")
)
Not programming related, but I'll answer anyway. It's in /etc/hosts

You can change it with a simple text editor such as nano

A clean way to download a file is:
import urllib
testfile = urllib.URLopener()
testfile.retrieve("http://randomsite.com/file.gz", "file.gz")
This downloads a file from a website and names it file.gz
. This is one of my favorite solutions, from Downloading a picture via urllib and python.
This example uses the urllib
library, and it will directly retrieve the file form a source.
In Python 2:
data = raw_input('Enter something: ')
print data
In Python 3:
data = input('Enter something: ')
print(data)
Running VS Code on Android is not possible, at least until Android support is implemented in Electron. This has been rejected by the Electron team in the past, see electron#562
Visual Studio Codespaces and GitHub Codespaces an upcoming services that enables running VS Code in a browser. Since everything runs in a browser, it seems likely that mobile OS' will be supported.
I write my answer in Python 2.7:
In Python, method overloading is not possible; if you really want access the same function with different features, I suggest you to go for method overriding.
class Base(): # Base class

print s'''
def add(self,a,b,c):
self.a=a
self.b=b
self.c=c
sum =a+b+c
print sum
class Derived(Base): # Derived class
def add(self,a,b): # overriding method
sum=a+b
print sum
add_fun_1=Base() #instance creation for Base class
add_fun_2=Derived()#instance creation for Derived class
add_fun_1.add(4,2,5) # function with 3 arguments
add_fun_2.add(4,2) # function with 2 arguments
It can be done, but you need to change the phpMyAdmin configuration, read this post: http://www.danielmois.com/article/Manage_remote_databases_from_localhost_with_phpMyAdmin
If for any reason the link dies, you can use the following steps:
config.inc.php
$cfg['Servers'][$i]['host']
variable, and set it to the IP or hostname of your remote server$cfg['Servers'][$i]['port']
variable, and set it to the remote mysql port. Usually this is 3306
$cfg['Servers'][$i]['user']
and $cfg['Servers'][$i]['password']
variables and set these to your username and password for the remote serverWithout proper server configuration, the connection may be slower than a local connection for example, it's would probably be slightly faster to use IP addresses instead of host names to avoid the server having to look up the IP address from the hostname.
In addition, remember that your remote database's username and password is stored in plain text when you connect like this, so you should take steps to ensure that no one can access this config file. Alternatively, you can leave the username and password variables empty to be prompted to enter them each time you log in, which is a lot more secure.
You can use the CONCAT
with CURDATE()
to the entire time of the day and then filter by using the BETWEEN
in WHERE
condition:
SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d')
FROM users
WHERE (users.signup_date BETWEEN CONCAT(CURDATE(), ' 00:00:00') AND CONCAT(CURDATE(), ' 23:59:59'))
I prefer to use <script>console.log({$varname|@json_encode})</script>
to log to the console.

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
"
Why is Asp.Net Identity IdentityDbContext a Black-Box?
How can I change the table names when using Visual Studio 2013 AspNet Identity?
Merge MyDbContext with IdentityDbContext"
To answer to all of these questions we need to understand that IdentityDbContext is just a class inherited from DbContext.
Let's take a look at IdentityDbContext source:

/// </summary>

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:
First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.
public class ApplicationDbContext
: IdentityDbContext
{
public ApplicationDbContext()
: base("DefaultConnection")
{
}
static ApplicationDbContext()
{
Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
// Add additional items here as needed
}
Extra Notes:
1) We can also change asp.net Identity default table names with the following solution:
public class ApplicationDbContext : IdentityDbContext
{
public ApplicationDbContext(): base("DefaultConnection")
{
}
protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<IdentityUser>().ToTable("user");
modelBuilder.Entity<ApplicationUser>().ToTable("user");
modelBuilder.Entity<IdentityRole>().ToTable("role");
modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
}
}
2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...
public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
public ApplicationRole()
{
this.Id = Guid.NewGuid().ToString();
}
public ApplicationRole(string name)
: this()
{
this.Name = name;
}
// Add any custom Role properties/code here
}
// Must be expressed in terms of our custom types:
public class ApplicationDbContext
: IdentityDbContext<ApplicationUser, ApplicationRole,
string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
public ApplicationDbContext()
: base("DefaultConnection")
{
}
static ApplicationDbContext()
{
Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
// Add additional items here as needed
}
To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.
Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code
Your file needs to be located inside your www directory. For example, if you're using wamp server on Windows, j3evn.jpg should be located,
C:/wamp/www/img/j3evn.jpg
and you can access it in html via
<img class="sealImage" alt="Image of Seal" src="../img/j3evn.jpg">
Look for the www, public_html, or html folder belonging to your web server. Place all your files and resources inside that folder.
Hope this helps!
I can see some people have asked, so on OSX you can still go to navigate->test or use cmd+shift+T
Remember you have to be focused in the class for this to work
In some (very specific) situations this might be achieved by using a filter. For example, you can change a blue SVG image to purple by rotating the hue 45 degrees using filter: hue-rotate(45deg);
. Browser support is minimal but it's still an interesting technique.
In Python 3, print is a function, you need to call it like print("hello world")
.
Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq
Save your JSON example to a file, say ex.json and then
yq -y '.' ex.json

I believe that the configure method expects an absolute path. Anyhow, you may also try to load a Properties object first:
Properties props = new Properties();
props.load(new FileInputStream("log4j.properties"));
PropertyConfigurator.configure(props);
If the properties file is in the jar, then you could do something like this:
Properties props = new Properties();
props.load(getClass().getResourceAsStream("/log4j.properties"));
PropertyConfigurator.configure(props);
The above assumes that the log4j.properties is in the root folder of the jar file.
Not really, you have to assign a variable. So
var bar = Stuff.Elements.Foo;
bar.Name = "Bob Dylan";
bar.Age = 68;
bar.Location = "On Tour";
bar.IsCool = True;
Or in C# 3.0:
var bar = Stuff.Elements.Foo
{
Name = "Bob Dylan",
Age = 68,
Location = "On Tour",
IsCool = True
};
To keep the code fluent (if code optimisation is not crucial) and you would need to do some further operations on the list:
authorsList = authorsList.Where(x => x.FirstName != "Bob").<do_some_further_Linq>;
or
authorsList = authorsList.Where(x => !setToRemove.Contains(x)).<do_some_further_Linq>;
In my case, there was a package with the same name as a missing import in the generated databinding class.. It seems like the compiler got confused.
I think the problem is that you are using type="text" instead of textarea. What you want is:
<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>
To clarify, a type="text" will always be one row, where-as a textarea can be multiple.
@AndroidDev solution worked for me. I had included the whole lib in gradle.
compile 'com.google.android.gms:play-services:8.4.0'
Changing to solved the problem. From 4 min to 1 min.
compile 'com.google.android.gms:play-services-ads:8.4.0'
compile 'com.google.android.gms:play-services-analytics:8.4.0'
Thnx
I came here because I was trying to use ifconfig on the container to find its IPAaddress and there was no ifconfig. If you really need ifconfig on the container go with @vishnu-narayanan answer above, however you may be able to get the information you need by using docker inspect on the host:
docker inspect <containerid>
There is lots of good stuff in the output including IPAddress of container:
"Networks": {
"bridge": {
"IPAMConfig": null,
"Links": null,
"Aliases": null,
"NetworkID": "12345FAKEID",
"EndpointID": "12345FAKEENDPOINTID",
"Gateway": "172.17.0.1",
"IPAddress": "172.17.0.3",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"MacAddress": "01:02:03:04:05:06",
"DriverOpts": null
}
}
You can use the && symbol between commands to execute the second command only if the first succeeds. More info here http://commandwindows.com/command1.htm
While both of the above answers work well if key,value are strings, I had a situation to append a string and integer (jq errors using the above expressions)

You can use System.IO.Path.GetFileName
to do this.
E.g.,
string[] files = Directory.GetFiles(dir);
foreach(string file in files)
Console.WriteLine(Path.GetFileName(file));
While you could use FileInfo
, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles
unless you need the additional functionality of the FileInfo
class.
Use a long datatype.
If you're using SQL Server 2008, there's a new featured called a User Defined Table Type. Here is an example of how to use it:
Create your User Defined Table Type:
CREATE TYPE [dbo].[StringList] AS TABLE(
[Item] [NVARCHAR](MAX) NULL
);
Next you need to use it properly in your stored procedure:
CREATE PROCEDURE [dbo].[sp_UseStringList]
@list StringList READONLY
AS
BEGIN
-- Just return the items we passed in
SELECT l.Item FROM @list l;
END
Finally here's some sql to use it in c#:
using (var con = new SqlConnection(connstring))
{
con.Open();
using (SqlCommand cmd = new SqlCommand("exec sp_UseStringList @list", con))
{
using (var table = new DataTable()) {
table.Columns.Add("Item", typeof(string));
for (int i = 0; i < 10; i++)
table.Rows.Add("Item " + i.ToString());
var pList = new SqlParameter("@list", SqlDbType.Structured);
pList.TypeName = "dbo.StringList";
pList.Value = table;
cmd.Parameters.Add(pList);
using (var dr = cmd.ExecuteReader())
{
while (dr.Read())
Console.WriteLine(dr["Item"].ToString());
}
}
}
}
To execute this from SSMS
DECLARE @list AS StringList
INSERT INTO @list VALUES ('Apple')
INSERT INTO @list VALUES ('Banana')
INSERT INTO @list VALUES ('Orange')
-- Alternatively, you can populate @list with an INSERT-SELECT
INSERT INTO @list
SELECT Name FROM Fruits
EXEC sp_UseStringList @list
This is actually a multi-step process. First you'll need to add all your files to the current stage:
git add .
You can verify that your files will be added when you commit by checking the status of the current stage:
git status
The console should display a message that lists all of the files that are currently staged, like this:
# On branch master
#
# Initial commit
#
# Changes to be committed:
# (use "git rm --cached <file>..." to unstage)
#
# new file: README
# new file: src/somefile.js
#
If it all looks good then you're ready to commit. Note that the commit action only commits to your local repository.
git commit -m "some message goes here"
If you haven't connected your local repository to a remote one yet, you'll have to do that now. Assuming your remote repository is hosted on GitHub and named "Some-Awesome-Project", your command is going to look something like this:
git remote add origin [email protected]:username/Some-Awesome-Project
It's a bit confusing, but by convention we refer to the remote repository as 'origin' and the initial local repository as 'master'. When you're ready to push your commits to the remote repository (origin), you'll need to use the 'push' command:
git push origin master

Be aware that in some rare cases there's a __slots__
property, such classes often have no __dict__

The problem is that you have not included bootstrap.min.css
. Also, the sequence of imports could be causing issue. Please try rearranging your resources as following:
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/css/bootstrap-datetimepicker.min.css" />

We can create method for it. Simply use it.
public func createBorderForView(color: UIColor, radius: CGFloat, width: CGFloat = 0.7) {
self.layer.borderWidth = width
self.layer.cornerRadius = radius
self.layer.shouldRasterize = false
self.layer.rasterizationScale = 2
self.clipsToBounds = true
self.layer.masksToBounds = true
let cgColor: CGColor = color.cgColor
self.layer.borderColor = cgColor
}
FULL is probably referring to a full table scan, which means that no indexes are in use. This is usually indicating that something is wrong, unless the query is supposed to use all the rows in a table.
Cost is a number that signals the sum of the different loads, processor, memory, disk, IO, and high numbers are typically bad. The numbers are added up when moving to the root of the plan, and each branch should be examined to locate the bottlenecks.
You may also want to query v$sql and v$session to get statistics about SQL statements, and this will have detailed metrics for all kind of resources, timings and executions.
Unlike IDs, tags are not used to identify views. Tags are essentially an extra piece of information that can be associated with a view. They are most often used as a convenience to store data related to views in the views themselves rather than by putting them in a separate structure.

You need to use:
await client.PostAsync(uri, content);
Something like that:
var comment = "hello world";
var questionId = 1;
var formContent = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("comment", comment),
new KeyValuePair<string, string>("questionId", questionId)
});
var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);
And if you need to get the response after post, you should use:
var stringContent = await response.Content.ReadAsStringAsync();
Hope it helps ;)
Every object has a __dict__
variable containing all the variables and its values in it.
Try this

>>> hi_obj.__dict__.keys()
The main difference between Abstract Factory and Factory Method is that Abstract Factory is implemented by Composition; but Factory Method is implemented by Inheritance.
Yes, you read that correctly: the main difference between these two patterns is the old composition vs inheritance debate.
UML diagrams can be found in the (GoF) book. I want to provide code examples, because I think combining the examples from the top two answers in this thread will give a better demonstration than either answer alone. Additionally, I have used terminology from the book in class and method names.
Abstract Factory
public class Client {
private final AbstractFactory_MessageQueue factory;
public Client(AbstractFactory_MessageQueue factory) {
// The factory creates message queues either for Azure or MSMQ.
// The client does not know which technology is used.
this.factory = factory;
}
public void sendMessage() {
//The client doesn't know whether the OutboundQueue is Azure or MSMQ.
OutboundQueue out = factory.createProductA();
out.sendMessage("Hello Abstract Factory!");
}
public String receiveMessage() {
//The client doesn't know whether the ReplyQueue is Azure or MSMQ.
ReplyQueue in = factory.createProductB();
return in.receiveMessage();
}
}
public interface AbstractFactory_MessageQueue {
OutboundQueue createProductA();
ReplyQueue createProductB();
}
public class ConcreteFactory_Azure implements AbstractFactory_MessageQueue {
@Override
public OutboundQueue createProductA() {
return new AzureMessageQueue();
}
@Override
public ReplyQueue createProductB() {
return new AzureResponseMessageQueue();
}
}
public class ConcreteFactory_Msmq implements AbstractFactory_MessageQueue {
@Override
public OutboundQueue createProductA() {
return new MsmqMessageQueue();
}
@Override
public ReplyQueue createProductB() {
return new MsmqResponseMessageQueue();
}
}
Factory Method
ConcreteCreator
is the client. In other words, the client is a subclass whose parent defines the factoryMethod()
. This is why we say that
Factory Method is implemented by Inheritance.Creator
(parent)
class invokes its own factoryMethod()
. If we remove
anOperation()
from the parent class, leaving only a single method
behind, it is no longer the Factory Method pattern. In other words,
Factory Method cannot be implemented with less than two methods in
the parent class; and one must invoke the other.public abstract class Creator {
public void anOperation() {
Product p = factoryMethod();
p.whatever();
}
protected abstract Product factoryMethod();
}
public class ConcreteCreator extends Creator {
@Override
protected Product factoryMethod() {
return new ConcreteProduct();
}
}
Misc. & Sundry Factory Patterns
Be aware that although the GoF define two different Factory patterns, these are not the only Factory patterns in existence. They are not even necessarily the most commonly used Factory patterns. A famous third example is Josh Bloch's Static Factory Pattern from Effective Java. The Head First Design Patterns book includes yet another pattern they call Simple Factory.
Don't fall into the trap of assuming every Factory pattern must match one from the GoF.
Take a look at this example: MDN Element.scrollHeight
I recommend that check out this example: stackoverflow.com/a/24815216... which implements a cross-browser handling for the scroll action.
You may use the following snippet:
//attaches the "scroll" event
$(window).scroll(function (e) {
var target = e.currentTarget,
scrollTop = target.scrollTop || window.pageYOffset,
scrollHeight = target.scrollHeight || document.body.scrollHeight;
if (scrollHeight - scrollTop === $(target).innerHeight()) {
console.log("? End of scroll");
}
});
There were some mistakes in harun's answer which are corrected below:
1) date where harun used getDay()
which is incorrect should be getDate()
2) getMonth()
gives one less month than actual month, So we should increment it by 1 as shown below
var date = new Date();
var day = date.getDate(); // yields
var month = date.getMonth() + 1; // yields month
var year = date.getFullYear(); // yields year
var hour = date.getHours(); // yields hours
var minute = date.getMinutes(); // yields minutes
var second = date.getSeconds(); // yields seconds
// After this construct a string with the above results as below
var time = day + "/" + month + "/" + year + " " + hour + ':' + minute + ':' + second;
Pass this string to codebehind function and accept it as a string parameter.Use the DateTime.ParseExact()
in codebehind to convert this string to DateTime
as follows,
DateTime.ParseExact(YourString, "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
This Worked for me! Hope this help you too.

Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct()
. Otherwise you get one user multiple times:
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

For AWK haters, and for simplicity, this contraption works for me:
help:
make -qpRr $(lastword $(MAKEFILE_LIST)) | egrep -v '(^(\.|:|#|\s|$)|=)' | cut -d: -f1
(for use outside a Makefile, just remove $(lastword ...)
or replace it with the Makefile path).
This solution will not work if you have "interesting" rule names but will work well for most simple setups. The main downside of a make -qp
based solution is (as in other answers here) that if the Makefile defines variable values using functions - they will still be executed regardless of -q
, and if using $(shell ...)
then the shell command will still be called and its side effects will happen. In my setup often the side effects of running shell functions is unwanted output to standard error, so I add 2>/dev/null
after the make command.
Simple and Efficient Solution : use Volley
StringRequest stringRequest = new StringRequest(Request.Method.GET, finalUrl ,
new Response.Listener<String>() {
@Override
public void onResponse(String){
try {
JSONObject jsonObject = new JSONObject(response);
HashMap<String, Object> responseHashMap = new HashMap<>(Utility.toMap(jsonObject)) ;
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("api", error.getMessage().toString());
}
});
RequestQueue queue = Volley.newRequestQueue(context) ;
queue.add(stringRequest) ;
Line magics are prefixed with the % character and work much like OS command-line calls: they get as an argument the rest of the line, where arguments are passed without parentheses or quotes. Cell magics are prefixed with a double %%, and they are functions that get as an argument not only the rest of the line, but also the lines below it in a separate argument.
<?php echo(count(array_slice(scandir($directory),2))); ?>
array_slice
works similary like substr
function, only it works with arrays.
For example, this would chop out first two array keys from array:
$key_zero_one = array_slice($someArray, 0, 2);
And if You ommit the first parameter, like in first example, array will not contain first two key/value pairs *('.' and '..').
In NHibernate (with NHibernate.Linq) you could do it as follows:
return session.Query<T>()
.Single(a => a.Filter == filter &&
a.Id == session.Query<T>()
.Where(a2 => a2.Filter == filter)
.Max(a2 => a2.Id));
Which will generate SQL like follows:
select *
from TableName foo
where foo.Filter = 'Filter On String'
and foo.Id = (select cast(max(bar.RowVersion) as INT)
from TableName bar
where bar.Name = 'Filter On String')
Which seems pretty efficient to me.
Create this class as Extension:
public static class Extensiones
{
public static string FolderName(this OpenFileDialog ofd)
{
string resp = "";
resp = ofd.FileName.Substring(0, 3);
var final = ofd.FileName.Substring(3);
var info = final.Split('\\');
for (int i = 0; i < info.Length - 1; i++)
{
resp += info[i] + "\\";
}
return resp;
}
}
Then, you could use in this way:
//ofdSource is an OpenFileDialog
if (ofdSource.ShowDialog(this) == DialogResult.OK)
{
MessageBox.Show(ofdSource.FolderName());
}
class ArrayComparator implements Comparator<Comparable[]> {
private final int columnToSort;
private final boolean ascending;
public ArrayComparator(int columnToSort, boolean ascending) {
this.columnToSort = columnToSort;
this.ascending = ascending;
}
public int compare(Comparable[] c1, Comparable[] c2) {
int cmp = c1[columnToSort].compareTo(c2[columnToSort]);
return ascending ? cmp : -cmp;
}
}
This way you can handle any type of data in those arrays (as long as they're Comparable) and you can sort any column in ascending or descending order.
String[][] data = getData();
Arrays.sort(data, new ArrayComparator(0, true));
PS: make sure you check for ArrayIndexOutOfBounds
and others.
EDIT: The above solution would only be helpful if you are able to actually store a java.util.Date
in the first column or if your date format allows you to use plain String comparison for those values. Otherwise, you need to convert that String to a Date, and you can achieve that using a callback interface (as a general solution). Here's an enhanced version:
class ArrayComparator implements Comparator<Object[]> {
private static Converter DEFAULT_CONVERTER = new Converter() {
@Override
public Comparable convert(Object o) {
// simply assume the object is Comparable
return (Comparable) o;
}
};
private final int columnToSort;
private final boolean ascending;
private final Converter converter;
public ArrayComparator(int columnToSort, boolean ascending) {
this(columnToSort, ascending, DEFAULT_CONVERTER);
}
public ArrayComparator(int columnToSort, boolean ascending, Converter converter) {
this.columnToSort = columnToSort;
this.ascending = ascending;
this.converter = converter;
}
public int compare(Object[] o1, Object[] o2) {
Comparable c1 = converter.convert(o1[columnToSort]);
Comparable c2 = converter.convert(o2[columnToSort]);
int cmp = c1.compareTo(c2);
return ascending ? cmp : -cmp;
}
}
interface Converter {
Comparable convert(Object o);
}
class DateConverter implements Converter {
private static final DateFormat df = new SimpleDateFormat("yyyy.MM.dd hh:mm");
@Override
public Comparable convert(Object o) {
try {
return df.parse(o.toString());
} catch (ParseException e) {
throw new IllegalArgumentException(e);
}
}
}
And at this point, you can sort on your first column with:
Arrays.sort(data, new ArrayComparator(0, true, new DateConverter());
I skipped the checks for nulls and other error handling issues.
I agree this is starting to look like a framework already. :)
Last (hopefully) edit: I only now realize that your date format allows you to use plain String comparison. If that is the case, you don't need the "enhanced version".
In iOS 6 you can easily use:
NSUUID *UUID = [NSUUID UUID];
NSString* stringUUID = [UUID UUIDString];

For a really thorough explanation and workaround, not only for indexOf but other array functions missing in IE check out the StackOverflow question Fixing JavaScript Array functions in Internet Explorer (indexOf, forEach, etc.)
If you aren't comfortable with using negative margins, check this out.
div {
position: fixed;
left: 50%;
bottom: 20px;
transform: translate(-50%, -50%);
margin: 0 auto;
}
<div>
Your Text
</div>
Especially useful when you don't know the width of the div.
align="center"
has no effect.
Since you have position:absolute
, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.
#manipulate {
position:absolute;
width:300px;
height:300px;
background:#063;
bottom:0px;
right:25%;
left:50%;
margin-left:-150px;
}
You have at least these 3 issues:
display
yet in your javascript you attempt to get element myDiv
which is not even defined in your markup.You can save all three values at once by doing:
var title=new Array();
var names=new Array();//renamed to names -added an S-
//to avoid conflicts with the input named "name"
var tickets=new Array();
function insert(){
var titleValue = document.getElementById('title').value;
var actorValue = document.getElementById('name').value;
var ticketsValue = document.getElementById('tickets').value;
title[title.length]=titleValue;
names[names.length]=actorValue;
tickets[tickets.length]=ticketsValue;
}
And then change the show function to:
function show() {
var content="<b>All Elements of the Arrays :</b><br>";
for(var i = 0; i < title.length; i++) {
content +=title[i]+"<br>";
}
for(var i = 0; i < names.length; i++) {
content +=names[i]+"<br>";
}
for(var i = 0; i < tickets.length; i++) {
content +=tickets[i]+"<br>";
}
document.getElementById('display').innerHTML = content; //note that I changed
//to 'display' because that's
//what you have in your markup
}
Here's a jsfiddle for you to play around.
You can use SelectionChanged event since you are using FullRowSelect selection mode. Than inside the handler you can access SelectedRows property and get data from it. Example:
private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
foreach (DataGridViewRow row in dataGridView.SelectedRows)
{
string value1 = row.Cells[0].Value.ToString();
string value2 = row.Cells[1].Value.ToString();
//...
}
}
You can also walk through the column collection instead of typing indexes...
Yet another/simple alternative (model identifier reference found at https://www.theiphonewiki.com/wiki/Models):
Updated answer for Swift 3/4/5 including string trimming and simulator support:
func modelIdentifier() -> String {
if let simulatorModelIdentifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] { return simulatorModelIdentifier }
var sysinfo = utsname()
uname(&sysinfo) // ignore return value
return String(bytes: Data(bytes: &sysinfo.machine, count: Int(_SYS_NAMELEN)), encoding: .ascii)!.trimmingCharacters(in: .controlCharacters)
}
You can also use it with Page Object Pattern, e.g:
Try this code:
@FindBy(xpath = "//*[contains(text(), 'Best Choice')]")
WebElement buttonBestChoice;
Do those changes in build.gradle
file in the wear module
compileSdkVersion 20
targetSdkVersion 20
So the final wear/build.gradle content will be:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "your package name"
minSdkVersion 20
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:+'
compile 'com.google.android.gms:play-services-wearable:+'
}
I suggest creating a test app (for dev environment only) on https://developers.facebook.com/apps and set: Website with Facebook Login
property to your localhost:[port] settings.
this option will work fine with no need to change hosts.
remember to change the appId back to your production app once you go live.
Edit - in the latest fb version you'll find it under the settings
tab.
in PHP if you use + for concatenation you will end up with this error. In php + is a arithmetic operator. https://www.php.net/manual/en/language.operators.arithmetic.php
wrong use of + operator:
"<label for='content'>Content:</label>"+
"<textarea class='form-control col-xs-12' rows='7'cols='100' id='content' name='content'>"+$initcontent+"</textarea>'"+
"</div>";
use . for concatenation
$output = "<div class='from-group'>".
"<label for='content'>Content:</label>".
"<textarea class='form-control col-xs-12' rows='7'cols='100' id='content' name='content'>".$initcontent."</textarea>'".
"</div>";
Hash
's key?
method tells you whether a given key is present or not.
session.key?("user")
I needed to add USE_FRM to the repair statement to make it work.
REPAIR TABLE <table_name> USE_FRM;
According to Apple documentation of NSDate compare:
Returns an NSComparisonResult value that indicates the temporal ordering of the receiver and another given date.
- (NSComparisonResult)compare:(NSDate *)anotherDate
Parameters
anotherDate
The date with which to compare the receiver. This value must not be nil. If the value is nil, the behavior is undefined and may change in future versions of Mac OS X.
Return Value
If:
The receiver and anotherDate are exactly equal to each other,
NSOrderedSame
The receiver is later in time than anotherDate,
NSOrderedDescending
The receiver is earlier in time than anotherDate,
NSOrderedAscending
In other words:
if ([date1 compare:date2] == NSOrderedSame) ...
Note that it might be easier in your particular case to read and write this :
if ([date2 isEqualToDate:date2]) ...
By JQuery using selectors
$("video_selector").trigger('play');
$("video_selector").trigger('pause');
$("div.video:first").trigger('play');$("div.video:first").trigger('pause');
$("#video_ID").trigger('play');$("#video_ID").trigger('pause');
By Javascript using ID
video_ID.play(); video_ID.pause();
OR
document.getElementById('video_ID').play(); document.getElementById('video_ID').pause();
Eclipse typically restarts after a plugin is installed. They do this using a wrapper eclipse.exe (launcher app) for windows. This application execs the core eclipse runner jar and if the eclipse java application terminates with a relaunch code, eclipse.exe restarts the workbench. You can build a similar bit of native code, shell script or another java code wrapper to achieve the restart.
Not sure about flexbox but you can do using the position property.
set parent div
position: relative
and child element which might be an <p>
or <h1>
etc.. set position: absolute
and bottom: 0
.
Example:
index.html
<div class="parent">
<p>Child</p>
</div>
style.css
.parent {
background: gray;
width: 10%;
height: 100px;
position: relative;
}
p {
position: absolute;
bottom: 0;
}
header files contain prototypes for functions you define in a .c or .cpp/.cxx file (depending if you're using c or c++). You want to place #ifndef/#defines around your .h code so that if you include the same .h twice in different parts of your programs, the prototypes are only included once.
client.h
#ifndef CLIENT_H
#define CLIENT_H
short socketConnect(char *host,unsigned short port,char *sendbuf,char *recievebuf, long rbufsize);
#endif /** CLIENT_H */
Then you'd implement the .h in a .c file like so:
client.c
#include "client.h"
short socketConnect(char *host,unsigned short port,char *sendbuf,char *recievebuf, long rbufsize) {
short ret = -1;
//some implementation here
return ret;
}
Not sure if the cleanest for long commands but certainly the easiest:
ssh user@host "cmd1; cmd2; cmd3"
This works for me.
