I have the same question.
You should add some dependencies in build.gradle, just looks like this
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':libcocos2dx')
compile 'com.google.firebase:firebase-ads:11.6.0'
// the key point line
compile 'com.google.android.gms:play-services-auth:11.6.0'
}
Remember Running Background, Running continuously are two different tasks.
For long-term background processes, Threads aren't optimal with Android. However, here's the code and do it at your own risk...
Remember Service or Thread will run in the background but our task needs to make trigger (call again and again) to get updates, i.e. once the task is completed we need to recall the function for next update.
Timer (periodic trigger), Alarm (Timebase trigger), Broadcast (Event base Trigger), recursion will awake our functions.
public static boolean isRecursionEnable = true;
void runInBackground() {
if (!isRecursionEnable)
// Handle not to start multiple parallel threads
return;
// isRecursionEnable = false; when u want to stop
// on exception on thread make it true again
new Thread(new Runnable() {
@Override
public void run() {
// DO your work here
// get the data
if (activity_is_not_in_background) {
runOnUiThread(new Runnable() {
@Override
public void run() {
// update UI
runInBackground();
}
});
} else {
runInBackground();
}
}
}).start();
}
Using Service: If you launch a Service it will start, It will execute the task, and it will terminate itself. after the task execution. terminated might also be caused by exception, or user killed it manually from settings. START_STICKY (Sticky Service) is the option given by android that service will restart itself if service terminated.
Remember the question difference between multiprocessing and multithreading? Service is a background process (Just like activity without UI), The same way how you launch thread in the activity to avoid load on the main thread (Activity thread), the same way you need to launch threads(or async tasks) on service to avoid load on service.
In a single statement, if you want a run a background continues task, you need to launch a StickyService and run the thread in the service on event base
I think you should give the data types of the column as NUMERIC or DOUBLE or FLOAT or REAL
Read http://sqlite.org/datatype3.html to more info.
You can also try:
{
"dateProp": { $gt: new Date('06/15/2016').getTime() }
}
You can convert String to Timestamp:
String inDate = "01-01-1990"
DateFormat df = new SimpleDateFormat("MM-dd-yyyy");
Timestamp ts = new Timestamp(((java.util.Date)df.parse(inDate)).getTime());
There is no 'built in' way to do this. Django will raise the DoesNotExist exception every time. The idiomatic way to handle this in python is to wrap it in a try catch:
try:
go = SomeModel.objects.get(foo='bar')
except SomeModel.DoesNotExist:
go = None
What I did do, is to subclass models.Manager, create a safe_get
like the code above and use that manager for my models. That way you can write: SomeModel.objects.safe_get(foo='bar')
.
In Asp.Net Core you can request the token directly, as documented:
@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@functions{
public string GetAntiXsrfRequestToken()
{
return Xsrf.GetAndStoreTokens(Context).RequestToken;
}
}
And use it in javascript:
function DoSomething(id) {
$.post("/something/todo/"+id,
{ "__RequestVerificationToken": '@GetAntiXsrfRequestToken()' });
}
You can add the recommended global filter, as documented:
services.AddMvc(options =>
{
options.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());
})
Update
The above solution works in scripts that are part of the .cshtml. If this is not the case then you can't use this directly. My solution was to use a hidden field to store the value first.
My workaround, still using GetAntiXsrfRequestToken
:
When there is no form:
<input type="hidden" id="RequestVerificationToken" value="@GetAntiXsrfRequestToken()">
The name
attribute can be omitted since I use the id
attribute.
Each form includes this token. So instead of adding yet another copy of the same token in a hidden field, you can also search for an existing field by name
. Please note: there can be multiple forms inside a document, so name
is in that case not unique. Unlike an id
attribute that should be unique.
In the script, find by id:
function DoSomething(id) {
$.post("/something/todo/"+id,
{ "__RequestVerificationToken": $('#RequestVerificationToken').val() });
}
An alternative, without having to reference the token, is to submit the form with script.
Sample form:
<form id="my_form" action="/something/todo/create" method="post">
</form>
The token is automatically added to the form as a hidden field:
<form id="my_form" action="/something/todo/create" method="post">
<input name="__RequestVerificationToken" type="hidden" value="Cf..." /></form>
And submit in the script:
function DoSomething() {
$('#my_form').submit();
}
Or using a post method:
function DoSomething() {
var form = $('#my_form');
$.post("/something/todo/create", form.serialize());
}

Generetic Action Sheet working for Swift 4, 4.2, 5
If you like a generic version that you can call from every ViewController
and in every project try this one:
class Alerts {
static func showActionsheet(viewController: UIViewController, title: String, message: String, actions: [(String, UIAlertActionStyle)], completion: @escaping (_ index: Int) -> Void) {
let alertViewController = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
for (index, (title, style)) in actions.enumerated() {
let alertAction = UIAlertAction(title: title, style: style) { (_) in
completion(index)
}
alertViewController.addAction(alertAction)
}
viewController.present(alertViewController, animated: true, completion: nil)
}
}
Call like this in your ViewController.
var actions: [(String, UIAlertActionStyle)] = []
actions.append(("Action 1", UIAlertActionStyle.default))
actions.append(("Action 2", UIAlertActionStyle.destructive))
actions.append(("Action 3", UIAlertActionStyle.cancel))
//self = ViewController
Alerts.showActionsheet(viewController: self, title: "D_My ActionTitle", message: "General Message in Action Sheet", actions: actions) { (index) in
print("call action \(index)")
/*
results
call action 0
call action 1
call action 2
*/
}
Attention: Maybe you're wondering why I add Action 1/2/3
but got results like 0,1,2. In the line for (index, (title, style)) in actions.enumerated()
I get the index of actions. Arrays always begin with the index 0. So the completion is 0,1,2.
If you like to set a enum, an id or another identifier I would recommend to hand over an object in parameter actions
.
Slightly updated answer, for MSSQL 2017, and using the SQL server management studio. I went mostly from these instructions https://www.sqlshack.com/sql-server-transaction-log-backup-truncate-and-shrink-operations/
I had a recent db backup, so I backed up the transaction log. Then I backed it up again for good measure. Finally I shrank the log file, and went from 20G to 7MB, much more in line with the size of my data. I don't think the transaction logs had ever been backed up since this was installed 2 years ago.. so putting that task on the housekeeping calendar.
What you also should consider, is keeping a reference to the created element, then you can easily remove it specificly:
var newUL = $('<ul><li>test</li></ul>');
$(this).append(newUL);
// Later ...
newUL.remove();
If you don't want to change the domain-wide default timeout, your best option is to change the deployment descriptor by setting the trans-timeout-seconds attribute in the weblogic-ejb-jar.xml - see http://docs.oracle.com/cd/E11035_01/wls100/jta/trxejb.html
This overrides the "Timeout Seconds" default, only for this specific EJB, while leaving all other EJB unaffected.
For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:
/Applications/mampstack-7.1.21-0/php/bin
In terminal run vim ~/.bash_profile
to open ~/.bash_profile
Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:
export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"
Hit ESC
, Type :wq
, and hit Enter
source ~/.bash_profile
which php
, output should be the path to MAMP PHP install.Use angular.bootstrap(element, [modules], [config])

Try this:
colnames(DF) = DF[1, ] # the first row will be the header
DF = DF[-1, ] # removing the first row.
However, get a look if the data has been properly read. If you data.frame has numeric variables but the first row were characters, all the data has been read as character. To avoid this problem, it's better to save the data and read again with header=TRUE as you suggest. You can also get a look to this question: Reading a CSV file organized horizontally.
Given the range A:A
, Id suggest:
=COUNTA(A:A)-(COUNTIF(A:A,"*")-COUNTIF(A:A,"?*"))
The problem is COUNTA over-counts by exactly the number of cells with zero length strings ""
.
The solution is to find a count of exactly these cells. This can be found by looking for all text cells and subtracting all text cells with at least one character
""
but excluding truly empty cells""
but excluding truly blank cellsThis means that the value COUNTIF(A:A,"*")-COUNTIF(A:A,"?*")
should be the number of text cells minus the number of text cells that have at least one character i.e. the count of cells containing exactly ""
Add bind(this) to your setTimeout callback function

A good way to do it in Node is to use the ajv
package (https://github.com/epoberezkin/ajv).
const Ajv = require('ajv');
const ajv = new Ajv({ allErrors: true, useDefaults: true, verbose: true });
const uuidSchema = { type: 'string', format: 'uuid' };
ajv.validate(uuidSchema, 'bogus'); // returns false
ajv.validate(uuidSchema, 'd42a8273-a4fe-4eb2-b4ee-c1fc57eb9865'); // returns true with v4 GUID
ajv.validate(uuidSchema, '892717ce-3bd8-11ea-b77f-2e728ce88125'); // returns true with a v1 GUID
The argument to remove()
is a filter document, so passing in an empty document means 'remove all':
db.user.remove({})
However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove()
call vs the drop()
call.
More details in the docs.
Here is another solution, If you are using ES6 using spread operator:
var arr = [0, 21, 22, 7];
const indexOfMaxValue = arr.indexOf(Math.max(...arr));
What is the line which gives exception ??
The reason for this is because the element to which you have referred is removed from the DOM structure
I was facing the same problem while working with IEDriver. The reason was because javascript loaded the element one more time after i have referred so my date reference pointed to an unexisting object even if it was right their on UI. I used the following workaround.
try {
WebElement date = driver.findElement(By.linkText(Utility.getSheetData(path, 7, 1, 2)));
date.click();
}
catch(org.openqa.selenium.StaleElementReferenceException ex)
{
WebElement date = driver.findElement(By.linkText(Utility.getSheetData(path, 7, 1, 2)));
date.click();
}
See if the same can help you !
just get postman from https://www.getpostman.com/docs/environments give it the file location with /test/test/1/_bulk?pretty command.
I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put
modelBuilder.Entity<Country>()
.HasMany(c => c.Users)
.WithOptional(c => c.Country)
.HasForeignKey(c => c.CountryId)
.WillCascadeOnDelete(false);
in DBContext class I am sorry for answer you very late :)
I don't actually find any of the presented solutions here to be fully complete so I'll add my own. Nothing new here. You can stitch this together from the other presented solutions plus various comments.
There are at least two things you'll have to make sure:
Make sure you pass the table name to the getTables()
method,
rather than passing a null value. In the first case you let the
database server filter the result for you, in the second you request
a list of all tables from the server and then filter the list
locally. The former is much faster if you are only searching for a
single table.
Make sure to check the table name from the resultset with an equals
match. The reason is that the getTables()
does pattern matching on
the query for the table and the _
character is a wildcard in SQL.
Suppose you are checking for the existence of a table named
EMPLOYEE_SALARY
. You'll then get a match on EMPLOYEESSALARY
too
which is not what you want.
Ohh, and do remember to close those resultsets. Since Java 7 you would want to use a try-with-resources statement for that.
Here's a complete solution:
public static boolean tableExist(Connection conn, String tableName) throws SQLException {
boolean tExists = false;
try (ResultSet rs = conn.getMetaData().getTables(null, null, tableName, null)) {
while (rs.next()) {
String tName = rs.getString("TABLE_NAME");
if (tName != null && tName.equals(tableName)) {
tExists = true;
break;
}
}
}
return tExists;
}
You may want to consider what you pass as the types
parameter (4th parameter) on your getTables()
call. Normally I would just leave at null
because you don't want to restrict yourself. A VIEW is as good as a TABLE, right? These days many databases allow you to update through a VIEW so restricting yourself to only TABLE type is in most cases not the way to go. YMMV.
Use [[:digit:]]
(note the double brackets) as the pattern:
$ hello=ho02123ware38384you443d34o3434ingtod38384day
$ echo ${hello//[[:digit:]]/}
howareyoudoingtodday
Just wanted to summarize the answers (especially @nickl-'s https://stackoverflow.com/a/22261334/2916086).
is null is the syntax I use for such things, when COALESCE is of no help.
Try:
if (@zipCode is null)
begin
([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)
end
else
begin
([Portal].[dbo].[Address].PostalCode=@zipCode )
end
Since the previous answers don't appear to work in with Visual Styles. You'll probably need to create your own class or extend the progress bar:
public class NewProgressBar : ProgressBar
{
public NewProgressBar()
{
this.SetStyle(ControlStyles.UserPaint, true);
}
protected override void OnPaint(PaintEventArgs e)
{
Rectangle rec = e.ClipRectangle;
rec.Width = (int)(rec.Width * ((double)Value / Maximum)) - 4;
if(ProgressBarRenderer.IsSupported)
ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle);
rec.Height = rec.Height - 4;
e.Graphics.FillRectangle(Brushes.Red, 2, 2, rec.Width, rec.Height);
}
}
EDIT: Updated code to make the progress bar use the visual style for the background
Arrays in Java have a fixed size, so you can't "add something at the end" as you could do in PHP.
A bit similar to the PHP behaviour is this:
int[] addElement(int[] org, int added) {
int[] result = Arrays.copyOf(org, org.length +1);
result[org.length] = added;
return result;
}
Then you can write:
x = new int[0];
x = addElement(x, 1);
x = addElement(x, 2);
System.out.println(Arrays.toString(x));
But this scheme is horribly inefficient for larger arrays, as it makes a copy of the whole array each time. (And it is in fact not completely equivalent to PHP, since your old arrays stays the same).
The PHP arrays are in fact quite the same as a Java HashMap with an added "max key", so it would know which key to use next, and a strange iteration order (and a strange equivalence relation between Integer keys and some Strings). But for simple indexed collections, better use a List in Java, like the other answerers proposed.
If you want to avoid using List
because of the overhead of wrapping every int in an Integer, consider using reimplementations of collections for primitive types, which use arrays internally, but will not do a copy on every change, only when the internal array is full (just like ArrayList). (One quickly googled example is this IntList class.)
Guava contains methods creating such wrappers in Ints.asList
, Longs.asList
, etc.
Had problems even when init.py existed in subfolder and all that was missing was adding 'as' after import
from folder.file import Class as Class
import folder.file as functions
You are missing spring-security-web-3.1.X.RELEASE.jar
from your classpath
IMHO this is the best way to write your line :
private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper =
new HashMap<Class<? extends Persistent>, PersistentHelper>();
This way the increased indentation without any braces can help you to see that the code was just splited because the line was too long. And instead of 4 spaces, 8 will make it clearer.
Using wrap=virtual
in your HTML form boxes gets rid of the horizontal scrollbar at the bottom of the box:
<textarea name= "enquiry" rows="4" cols="30" wrap="virtual"></textarea>
See example here : http://jsbin.com/opube3/2 (Tested on FF and IE)
I think you can also use match()
:
largetable$HouseTypeNo <- with(lookup,
HouseTypeNo[match(largetable$HouseType,
HouseType)])
This still works if I scramble the order of lookup
.
I've used Beej's Guide to Network Programming in the past. It's in C, not C++, but the examples are good. Go directly to section 6 for the simple client and server example programs.
On python command line, first import that module for which you need location.
import module_name
Then type:
print(module_name.__file__)
For example to find out "pygal" location:
import pygal
print(pygal.__file__)
Output:
/anaconda3/lib/python3.7/site-packages/pygal/__init__.py
Just change the port to 8081
and following virtual host will work:
<VirtualHost *:8081>
ServerName comm-app.local
DocumentRoot "C:/xampp/htdocs/CommunicationApp/public"
SetEnv APPLICATION_ENV "development"
<Directory "C:/xampp/htdocs/CommunicationApp/public">
DirectoryIndex index.php
AllowOverride All
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
I had the same issue for a specific controller only - which was really weird. I had a folder in the root of the CI folder that had the same name as the controller I was trying to access... Because of that, CI was directing the request to this directory instead of the controller itself.
After removing this folder (which was there a bit by mistake), it all worked fine.
To be more clear, here is what it looked like:
/ci/controller/register.php
/ci/register/
I had to remove /ci/register/
.
To be more precise the shebang #!
, when it is the first two bytes of an executable (x
mode) file, is interpreted by the execve(2) system call (which execute programs). But POSIX specification for execve
don't mention the shebang.
It must be followed by a file path of an interpreter executable (which BTW could even be relative, but most often is absolute).
A nice trick (or perhaps not so nice one) to find an interpreter (e.g. python
) in the user's $PATH
is to use the env
program (always at /usr/bin/env
on all Linux) like e.g.
#!/usr/bin/env python
Any ELF executable can be an interpreter. You could even use #!/bin/cat
or #!/bin/true
if you wanted to! (but that would be often useless)
Easiest way:
// Prefs.h
#define PREFS_MY_CONSTANT @"prefs_my_constant"
Better way:
// Prefs.h
extern NSString * const PREFS_MY_CONSTANT;
// Prefs.m
NSString * const PREFS_MY_CONSTANT = @"prefs_my_constant";
One benefit of the second is that changing the value of a constant does not cause a rebuild of your entire program.

android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal"
android:indeterminateDuration="10"
android:indeterminateBehavior="repeat"

You can trigger a file input element by sending it a Javascript click event, e.g.
<input type="file" ... id="file-input">
$("#file-input").click();
You could put this in a click event handler for the image, for instance, then hide the file input with CSS. It'll still work even if it's invisible.
Once you've got that part working, you can set a change
event handler on the input element to see when the user puts a file into it. This event handler can create a temporary "blob" URL for the image by using window.URL.createObjectURL
, e.g.:
var file = document.getElementById("file-input").files[0];
var blob_url = window.URL.createObjectURL(file);
That URL can be set as the src
for an image on the page. (It only works on that page, though. Don't try to save it anywhere.)
Note that not all browsers currently support camera capture. (In fact, most desktop browsers don't.) Make sure your interface still makes sense if the user gets asked to pick a file.
You will then be able to push it to the remote repository, for example if that is your way of keeping a copy (backup) and making sure nothing gets lost.
You can fetch the remote branch to have a local copy and examine the differences between (i) what the remote had (with the old branch name) and (ii) what you have (with the new branch name), and decide what to do. Since you weren't aware of the remote's differences in the first place (hence the problem), simply merging or forcing changes somewhere is far too brutal.
Look at the differences, pick which branch you want to work on, cherry pick changes you want from the other branch, or revert changes you don't want on the branch you've got etc.
Then you should be in a position to decide whether you want to force your clean version onto the remote, or add new changes, or whatever.

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)
/etc/squid3/squid.conf
instead of the super bloated default config file
auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
# Choose the port you want. Below we set it to default 3128.
http_port 3128
Please note the basic_ncsa_auth program instead of the old ncsa_auth
For squid 2.x you need to edit /etc/squid/squid.conf
file and place:
auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
sudo htpasswd -c /etc/squid3/passwords username_you_like
and enter a password twice for the chosen username then
sudo service squid3 restart
sudo htpasswd -c /etc/squid/passwords username_you_like
and enter a password twice for the chosen username then
sudo service squid restart
For the many people that asked me: the 2 tools produce different file formats:
htdigest
stores the password in plain text.htpasswd
stores the password hashed (various hashing algos are available)Despite this difference in format basic_ncsa_auth
will still be able to parse a password file generated with htdigest
. Hence you can alternatively use:
sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like
Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.
On Ubuntu 14.04 htdigest
and htpasswd
are both available in the [apache2-utils][1]
package.
Similar as above applies, but file paths are different.
Install squid
brew install squid
Start squid service
brew services start squid
Squid config file is stored at /usr/local/etc/squid.conf
.
Comment or remove following line:
http_access allow localnet
Then similar to linux config (but with updated paths) add this:
auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
Note that path to basic_ncsa_auth
may be different since it depends on installed version when using brew
, you can verify this with ls /usr/local/Cellar/squid/
. Also note that you should add the above just bellow the following section:
#

You don't need to instantiate the ViewController in Storyboard just to get present()
ViewController to work. That's a hackish solution.
If you see a black/blank screen when presenting a VC, it might be because you're calling present()
from viewDidLoad()
in the First/RootViewController, but the first View isn't ready yet.
Call present()
from viewDidAppear
to fix this, i.e.:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let yourVC = YourViewController()
self.present(yourVC, animated: true, completion: nil)
}
Once any "View" has appeared in your App, you can start calling present() from viewDidLoad()
.
Using UINavigationController
(as suggested in an answer) is another option, but it might be an overkill to solve this issue. You might end up complicating the user flow. Use the UINavigationController
based solution only if you want to have a NavigatonBar or want to return to the previous view controller.
-ErrorAction Stop
is changing things for you. Try adding this and see what you get:
Catch [System.Management.Automation.ActionPreferenceStopException] {
"caught a StopExecution Exception"
$error[0]
}
throw new RuntimeException(msg);
You need the new
in there. It's creating an instance and throwing it, not calling a method.
Just use cd /d %root%
to switch driver letters and change directories.
Alternatively, use pushd %root%
to switch drive letters when changing directories as well as storing the previous directory on a stack so you can use popd
to switch back.
Note that pushd
will also allow you to change directories to a network share. It will actually map a network drive for you, then unmap it when you execute the popd
for that directory.
To get every part of the URL except for the query:
var url = (location.origin).concat(location.pathname).concat(location.hash);
Note that this includes the hash as well, if there is one (I'm aware there's no hash in your example URL, but I included that aspect for completeness). To eliminate the hash, simply exclude .concat(location.hash)
.
It's better practice to use concat
to join Javascript strings together (rather than +
): in some situations it avoids problems such as type confusion.
<button class="btn" onClick="openDialog('New Type','Sample.html')">Middle</button>
<script type="text/javascript">
function openDialog(title,url) {
$('.opened-dialogs').dialog("close");
$('<div class="opened-dialogs">').html('loading...').dialog({
position: ['center',20],
open: function () {
$(this).load(url);
},
close: function(event, ui) {
$(this).remove();
},
title: title,
minWidth: 600
});
return false;
}
</script>
Object-oriented approach
It's good practice to make object sorting logic, if applicable, a property of the class rather than incorporated in each instance the ordering is required.
This ensures consistency and removes the need for boilerplate code.
At a minimum, you should specify __eq__
and __lt__
operations for this to work. Then just use sorted(list_of_objects)
.
class Card(object):
def __init__(self, rank, suit):
self.rank = rank
self.suit = suit
def __eq__(self, other):
return self.rank == other.rank and self.suit == other.suit
def __lt__(self, other):
return self.rank < other.rank
hand = [Card(10, 'H'), Card(2, 'h'), Card(12, 'h'), Card(13, 'h'), Card(14, 'h')]
hand_order = [c.rank for c in hand] # [10, 2, 12, 13, 14]
hand_sorted = sorted(hand)
hand_sorted_order = [c.rank for c in hand_sorted] # [2, 10, 12, 13, 14]
JSON can be written into local storage using the JSON.stringify to serialize a JS object. You cannot write to a JSON file using only JS. Only cookies or local storage
var obj = {"nissan": "sentra", "color": "green"};
localStorage.setItem('myStorage', JSON.stringify(obj));
And to retrieve the object later
var obj = JSON.parse(localStorage.getItem('myStorage'));
You could also check my md5 implementation. It should be approx. the same as the other posted above. Unfortunately, the performance is limited by the inner loop which is impossible to optimize more.
You can just post the file name to delete to delete.php on the server, which can easily unlink() the file.
Use adb. With adb pull you can copy files from your device to your system, when the device is attached with USB.
Of course you also need the right permissions to access the directory your file is in. If not, you will need to root the device first.
If you find that many of the APKs are named "base.apk" you can also use this one line command to pull all the APKs off a phone you can access while renaming any "base.apk" names to the package name. This also fixes the directory not found issue for APK paths with seemingly random characters after the name:
for i in $(adb shell pm list packages | awk -F':' '{print $2}'); do adb pull "$(adb shell pm path $i | awk -F':' '{print $2}')"; mv base.apk $i.apk 2&> /dev/null ;done
If you get "adb: error: failed to stat remote object" that indicates you don't have the needed permissions. I ran this on a NON-rooted Moto Z2 and was able to download ALL the APKs I did not uninstall (see below) except youtube.
adb shell pm uninstall --user 0 com.android.cellbroadcastreceiver <--- kills presidential alert app!
(to view users run adb shell pm list users) This is a way to remove/uninstall (not from the phone as it comes back with factory reset) almost ANY app WITHOUT root INCLUDING system apps (hint the annoying update app that updates your phone line it or not can be found by grepping for "ccc")
First you need to include the JSTL tags :-
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
at the start of the page
You can use :
abs_num = (num < 0) ? -num : num;
I believe this is what you're looking for:
Convert Decimal Numbers to Text showing only the non-zero decimals
Especially this line might be helpful:
StringVar text := Totext ( {Your.NumberField} , 6 , "" ) ;
The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.
The enumerate function works as follows:
doc = """I like movie. But I don't like the cast. The story is very nice"""
doc1 = doc.split('.')
for i in enumerate(doc1):
print(i)
The output is
(0, 'I like movie')
(1, " But I don't like the cast")
(2, ' The story is very nice')
For me, all I had to do it uninstalling VMware.

In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...

@parameter_1_Name = 'parameter_1_Value',
@parameter_2_name = 'parameter_2_value',
@parameter_z_name = 'parameter_z_value'
Make resource controller with Model.
php artisan make:controller PostController --model=Post
You can also do this with reduce:
let arr = [1, 2, 3]
arr.reduce((xs, x, index) => {
if (index == 0) {
return xs
} else {
return xs.concat(x)
}
}, Array())
// Or if you like a oneliner
arr.reduce((xs, x, index) => index == 0 ? xs : xs.concat(x), Array())

In the terminal:
$ alias <name_of_your_alias>_$argname="<command> $argname"
and to use it:
$<name_of_your_alias>_$argname
for example, a alias to cat
a file called hello.txt
:
CAT_FILE_
)$f
(is the $argname
, which is a file in this example)$ alias CAT_FILE_$f="cat $f"
$ echo " " >> hello.txt
$ echo "hello there!" >> hello.txt
$ echo " " >> hello.txt
$ cat hello.txt
hello there!
Test:
CAT_FILE_ hello.txt

You could use numpy.fromfile
, which can read data from both text and binary files. You would first construct a data type, which represents your file format, using numpy.dtype
, and then read this type from file using numpy.fromfile
.

To get the value of a drop-down (select) element, just use val().
$('._someDropDown').live('change', function(e) {
alert($(this).val());
});
If you want to the text of the selected option, using this:
$('._someDropDown').live('change', function(e) {
alert($('[value=' + $(this).val() + ']', this).text());
});

on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
update B

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.
From a background script you can listen to the chrome.tabs.onUpdated
event and check the property changeInfo.status
on the callback. It can be loading or complete. If it is complete, do the action.
Example:
chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
if (changeInfo.status == 'complete') {
// do your things
}
})
Because this will probably trigger on every tab completion, you can also check if the tab is active
on its homonymous attribute, like this:
chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
if (changeInfo.status == 'complete' && tab.active) {
// do your things
}
})
It is worth mentioning that 2>&1 means that standard error will be redirected too, together with standard output. So
someCommand | tee someFile
gives you just the standard output in the file, but not the standard error: standard error will appear in console only. To get standard error in the file too, you can use
someCommand 2>&1 | tee someFile
(source: In the shell, what is " 2>&1 "? ). Finally, both the above commands will truncate the file and start clear. If you use a sequence of commands, you may want to get output&error of all of them, one after another. In this case you can use -a flag to "tee" command:
someCommand 2>&1 | tee -a someFile
One very very important difference. Since Observable is just a function, it does not have any state, so for every new Observer, it executes the observable create code again and again. This results in:
The code is run for each observer . If its a HTTP call, it gets called for each observer
This causes major bugs and inefficiencies
BehaviorSubject (or Subject ) stores observer details, runs the code only once and gives the result to all observers .
Ex:
JSBin: http://jsbin.com/qowulet/edit?js,console
// --- Observable ---_x000D_
let randomNumGenerator1 = Rx.Observable.create(observer => {_x000D_
observer.next(Math.random());_x000D_
});_x000D_
_x000D_
let observer1 = randomNumGenerator1_x000D_
.subscribe(num => console.log('observer 1: '+ num));_x000D_
_x000D_
let observer2 = randomNumGenerator1_x000D_
.subscribe(num => console.log('observer 2: '+ num));_x000D_
_x000D_
_x000D_
// ------ BehaviorSubject/ Subject_x000D_
_x000D_
let randomNumGenerator2 = new Rx.BehaviorSubject(0);_x000D_
randomNumGenerator2.next(Math.random());_x000D_
_x000D_
let observer1Subject = randomNumGenerator2_x000D_
.subscribe(num=> console.log('observer subject 1: '+ num));_x000D_
_x000D_
let observer2Subject = randomNumGenerator2_x000D_
.subscribe(num=> console.log('observer subject 2: '+ num));
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/rxjs/5.5.3/Rx.min.js"></script>
_x000D_
Output :
"observer 1: 0.7184075243594013"
"observer 2: 0.41271850211336103"
"observer subject 1: 0.8034263165479893"
"observer subject 2: 0.8034263165479893"
Observe how using Observable.create
created different output for each observer, but BehaviorSubject
gave the same output for all observers. This is important.

To do this, I had to come up with an intermediate data structure:
class KeyDataPoint {
String key;
DateTime timestamp;
Number data;
// obvious constructor and getters
}
With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.
Then, we apply a groupingBy
operation on the string key in order to gather the data for each key together. Note that a simple groupingBy
would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy
which is a mapping
operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping
operation is simply toList
which collects the DataPoint objects of the same group into a list.
Now we have a Map<String, List<DataPoint>>
and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.
The code ends up looking like this:
Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
return multiDataPoints.stream()
.flatMap(mdp -> mdp.getData().entrySet().stream()
.map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
.collect(groupingBy(KeyDataPoint::getKey,
mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
.entrySet().stream()
.map(e -> new DataSet(e.getKey(), e.getValue()))
.collect(toList());
}
I took some liberties with constructors and getters, but I think they should be obvious.
Console.Write((int)response.StatusCode);
HttpStatusCode (the type of response.StatusCode
) is an enumeration where the values of the members match the HTTP status codes, e.g.
public enum HttpStatusCode
{
...
Moved = 301,
OK = 200,
Redirect = 302,
...
}
How about putting all content inside link?
<li><a href="#" onClick="..." ... >Backpack <img ... /></a></li>
Seems like the most natural thing to try.
A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:
Reader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);
Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don't specify it, the system default is assumed.
Eric Lippert wrote a detailed blog post about this subject a while back (additionally comparing it to VBScript). More accurately, he wrote about JScript, which is Microsoft's own implementation of ECMAScript, although very similar to JavaScript. I would imagine that you can assume the vast majority of behaviour would be the same for the JavaScript engine of Internet Explorer. Of course, the implementation will vary from browser to browser, though I suspect you could take a number of the common principles and apply them to other browsers.
Quoted from that page:
JScript uses a nongenerational mark-and-sweep garbage collector. It works like this:
Every variable which is "in scope" is called a "scavenger". A scavenger may refer to a number, an object, a string, whatever. We maintain a list of scavengers -- variables are moved on to the scav list when they come into scope and off the scav list when they go out of scope.
Every now and then the garbage collector runs. First it puts a "mark" on every object, variable, string, etc – all the memory tracked by the GC. (JScript uses the VARIANT data structure internally and there are plenty of extra unused bits in that structure, so we just set one of them.)
Second, it clears the mark on the scavengers and the transitive closure of scavenger references. So if a scavenger object references a nonscavenger object then we clear the bits on the nonscavenger, and on everything that it refers to. (I am using the word "closure" in a different sense than in my earlier post.)
At this point we know that all the memory still marked is allocated memory which cannot be reached by any path from any in-scope variable. All of those objects are instructed to tear themselves down, which destroys any circular references.
The main purpose of garbage collection is to allow the programmer not to worry about memory management of the objects they create and use, though of course there's no avoiding it sometimes - it is always beneficial to have at least a rough idea of how garbage collection works.
Historical note: an earlier revision of the answer had an incorrect reference to the delete
operator. In JavaScript the delete
operator removes a property from an object, and is wholly different to delete
in C/C++.
The only way to do explicit scaling in CSS is to use tricks such as found here.
IE6 only, you could also use filters (check out PNGFix). But applying them automatically to the page will need javascript, though that javascript could be embedded in the CSS file.
If you are going to require javascript, then you might want to just have javascript fill in the missing value for the height by inspecting the image once the content has loaded. (Sorry I do not have a reference for this technique).
Finally, and pardon me for this soapbox, you might want to eschew IE6 support in this matter. You could add _width: auto
after your width: 75px
rule, so that IE6 at least renders the image reasonably, even if it is the wrong size.
I recommend the last solution simply because IE6 is on the way out: 20% and going down almost a percent a month. Also, I note that your site is recreational and in the UK. Both of these help the demographic lean to be away from IE6: IE6 usage drops nearly 40% during weekends (no citation sorry), and UK has a much lower IE6 demographic (again no citation, sorry).
Good luck!
I came across this problem some day using colab. And I find the most painless way is just running this code before printing. Everything works like charm then.

document.documentElement.style.height=(window.outerHeight/window.devicePixelRatio)+'px';
setTimeout(window.scrollTo(1,1),0);
}
window.addEventListener("load",function(){hideAddressBar();});
window.addEventListener("orientationchange",function(){hideAddressBar();});
It should work with the iPhone also, but I couldn't test this.
Updated Code:
Swift 5.0
extension UITextField {
func addUnderline() {
let layer = CALayer()
layer.backgroundColor = #colorLiteral(red: 0.6666666865, green: 0.6666666865, blue: 0.6666666865, alpha: 1)
layer.frame = CGRect(x: 0.0, y: self.frame.size.height - 1.0, width: self.frame.size.width, height: 1.0)
self.clipsToBounds = true
self.layer.addSublayer(layer)
self.setNeedsDisplay()} }
Now call this func in viewDidLayoutSubviews()
override func viewDidLayoutSubviews() {
textField.addUnderline()
}
NOTE: This method will only work in viewDidLayoutSubviews()
I originally used Plantface's answer, but I didn't like how the syntax looked in my view.
I reworked it to use $q.defer to post-process the data and return a list on unique teams, which is then uses as the filter.
http://plnkr.co/edit/waWv1donzEMdsNMlMHBa?p=preview
<ul>
<li ng-repeat="team in teams">{{team}}
<ul>
<li ng-repeat="player in players | filter: {team: team}">{{player.name}}</li>
</ul>
</li>
</ul>
app.controller('MainCtrl', function($scope, $q) {
$scope.players = []; // omitted from SO for brevity
// create a deferred object to be resolved later
var teamsDeferred = $q.defer();
// return a promise. The promise says, "I promise that I'll give you your
// data as soon as I have it (which is when I am resolved)".
$scope.teams = teamsDeferred.promise;
// create a list of unique teams. unique() definition omitted from SO for brevity
var uniqueTeams = unique($scope.players, 'team');
// resolve the deferred object with the unique teams
// this will trigger an update on the view
teamsDeferred.resolve(uniqueTeams);
});

When you create a new File
, you are supposed to provide the file name, not only the directory you want to put your file in.
Try with something like
File file = new File("D:/Data/" + item.getFileName());
That works fine with font icons like 's7 stroke icons' and 'font-awesome':
.mirror {
display: inline-block;
transform: scaleX(-1);
}
And then on target element:
<button>
<span class="s7-back mirror"></span>
<span>Next</span>
</button>
If you want to pass data between two actions during a redirect without include any data in the query string, put the model in the TempData object.
ACTION
TempData["datacontainer"] = modelData;
VIEW
var modelData= TempData["datacontainer"] as ModelDataType;
TempData is meant to be a very short-lived instance, and you should only use it during the current and the subsequent requests only! Since TempData works this way, you need to know for sure what the next request will be, and redirecting to another view is the only time you can guarantee this.
Therefore, the only scenario where using TempData will reliably work is when you are redirecting.
You can use pageshow
event to handle situation when browser navigates to your page through history traversal:
window.addEventListener( "pageshow", function ( event ) {
var historyTraversal = event.persisted ||
( typeof window.performance != "undefined" &&
window.performance.navigation.type === 2 );
if ( historyTraversal ) {
// Handle page restore.
window.location.reload();
}
});
Note that HTTP cache may be involved too. You need to set proper cache related HTTP headers on server to cache only those resources that need to be cached. You can also do forced reload to instuct browser to ignore HTTP cache: window.location.reload( true )
. But I don't think that it is best solution.
For more information check:
"var" is one of those things that people either love or hate (like regions). Though, unlike regions, var is absolutely necessary when creating anonymous classes.
To me, var makes sense when you are newing up an object directly like:
var dict = new Dictionary<string, string>();
That being said, you can easily just do:
Dictionary<string, string> dict =
new and intellisense will fill in the rest for you here.
If you only want to work with a specific interface, then you can't use var unless the method you are calling returns the interface directly.
Resharper seems to be on the side of using "var" all over, which may push more people to do it that way. But I kind of agree that it is harder to read if you are calling a method and it isn't obvious what is being returned by the name.
var itself doesn't slow things down any, but there is one caveat to this that not to many people think about. If you do var result = SomeMethod();
then the code after that is expecting some sort of result back where you'd call various methods or properties or whatever. If SomeMethod()
changed its definition to some other type but it still met the contract the other code was expecting, you just created a really nasty bug (if no unit/integration tests, of course).
Just for posterity, here's the text from several external sources regarding the Excel file formats. Some of these have been mentioned in other answers to this question but without reproducing the essential content.
1. From Doug Mahugh, August 22, 2006:
...the new XLSB binary format. Like Open XML, it’s a full-fidelity file format that can store anything you can create in Excel, but the XLSB format is optimized for performance in ways that aren’t possible with a pure XML format.
The XLSB format (also sometimes referred to as BIFF12, as in “binary file format for Office 12”) uses the same Open Packaging Convention used by the Open XML formats and XPS. So it’s basically a ZIP container, and you can open it with any ZIP tool to see what’s inside. But instead of .XML parts within the package, you’ll find .BIN parts...
This article also refers to documentation about the BIN format, too lengthy to reproduce here.
2. From MSDN Archive, August 29, 2006 which in turn cites an already-missing blog post regarding the XLSB format:
Even though we’ve done a lot of work to make sure that our XML formats open quickly and efficiently, this binary format is still more efficient for Excel to open and save, and can lead to some performance improvements for workbooks that contain a lot of data, or that would require a lot of XML parsing during the Open process. (In fact, we’ve found that the new binary format is faster than the old XLS format in many cases.) Also, there is no macro-free version of this file format – all XLSB files can contain macros (VBA and XLM). In all other respects, it is functionally equivalent to the XML file format above:
File size – file size of both formats is approximately the same, since both formats are saved to disk using zip compression Architecture – both formats use the same packaging structure, and both have the same part-level structures. Feature support – both formats support exactly the same feature set Runtime performance – once loaded into memory, the file format has no effect on application/calculation speed Converters – both formats will have identical converter support
print reduce(lambda x, y: x + y, l)/(len(l)*1.0)
or like posted previously
sum(l)/(len(l)*1.0)
The 1.0 is to make sure you get a floating point division
Also if you use Spring Actuator org.springframework.boot.actuate.autoconfigure.jdbc.DataSourceHealthContributorAutoConfiguration
might be initializing DataSource as well.
Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-)
.
I've found this to work very well. It uses the .range property of the .autofilter object, which seems to be a rather obscure, but very handy, feature:
Sub copyfiltered()
' Copies the visible columns
' and the selected rows in an autofilter
'
' Assumes that the filter was previously applied
'
Dim wsIn As Worksheet
Dim wsOut As Worksheet
Set wsIn = Worksheets("Sheet1")
Set wsOut = Worksheets("Sheet2")
' Hide the columns you don't want to copy
wsIn.Range("B:B,D:D").EntireColumn.Hidden = True
'Copy the filtered rows from wsIn and and paste in wsOut
wsIn.AutoFilter.Range.Copy Destination:=wsOut.Range("A1")
End Sub
You should pass the reference to request like below
var options = { ... }_x000D_
var req = http.request(options, function(res) {_x000D_
// Usual stuff: on(data), on(end), chunks, etc..._x000D_
});_x000D_
_x000D_
req.setTimeout(60000, function(){_x000D_
this.abort();_x000D_
}).bind(req);_x000D_
req.write('something');_x000D_
req.end();
_x000D_
Request error event will get triggered
req.on("error", function(e){_x000D_
console.log("Request Error : "+JSON.stringify(e));_x000D_
});
_x000D_
There are two elements in array and this definitely doesn't mean that array is empty. As a quick workaround you can do following:
$errors = array_filter($errors);
if (!empty($errors)) {
}
array_filter()
function's default behavior will remove all values from array which are equal to null
, 0
, ''
or false
.
Otherwise in your particular case empty()
construct will always return true
if there is at least one element even with "empty" value.
To get the cell value, you need to read it directly from DataGridView1
using e.RowIndex
and e.ColumnIndex
properties.
Eg:
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim value As Object = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
If IsDBNull(value) Then
TextBox1.Text = "" ' blank if dbnull values
Else
TextBox1.Text = CType(value, String)
End If
End Sub
If you want to terminate the thread, then just returning is fine. You do NOT need to call Thread.currentThread().interrupt()
(it will not do anything bad though. It's just that you don't need to.) This is because interrupt()
is basically used to notify the owner of the thread (well, not 100% accurate, but sort of). Because you are the owner of the thread, and you decided to terminate the thread, there is no one to notify, so you don't need to call it.
By the way, why in the first case we need to use currentThread? Is Thread does not refer to the current thread?
Yes, it doesn't. I guess it can be confusing because e.g. Thread.sleep() affects the current thread, but Thread.sleep() is a static method.
If you are NOT the owner of the thread (e.g. if you have not extended Thread
and coded a Runnable
etc.) you should do
Thread.currentThread().interrupt();
return;
This way, whatever code that called your runnable will know the thread is interrupted = (normally) should stop whatever it is doing and terminate. As I said earlier, it is just a mechanism of communication though. The owner might simply ignore the interrupted status and do nothing.. but if you do set the interrupted status, somebody might thank you for that in the future.
For the same reason, you should never do
Catch(InterruptedException ie){
//ignore
}
Because if you do, you are stopping the message there. Instead one should do
Catch(InterruptedException ie){
Thread.currentThread().interrupt();//preserve the message
return;//Stop doing whatever I am doing and terminate
}
You need to use IBOutlet and IBAction if you are using interface builder (hence the IB prefix) for your GUI components. IBOutlet is needed to associate properties in your application with components in IB, and IBAction is used to allow your methods to be associated with actions in IB.
For example, suppose you define a button and label in IB. To dynamically change the value of the label by pushing the button, you will define an action and property in your app similar to:
UILabel IBOutlet *myLabel;
- (IBAction)pushme:(id)sender;
Then in IB you would connect myLabel with the label and connect the pushme method with the button. You need IBAction and IBOutlet for these connections to exist in IB.
You can use <LinearLayout>
to group elements horizontaly. Also you should use style to set margins, background and other properties. This will allow you not to repeat code for every label you use.
Here is an example:
<LinearLayout
style="@style/FormItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
style="@style/FormLabel"
android:layout_width="wrap_content"
android:layout_height="@dimen/default_element_height"
android:text="@string/name_label"
/>
<EditText
style="@style/FormText.Editable"
android:id="@+id/cardholderName"
android:layout_width="wrap_content"
android:layout_height="@dimen/default_element_height"
android:layout_weight="1"
android:gravity="right|center_vertical"
android:hint="@string/card_name_hint"
android:imeOptions="actionNext"
android:singleLine="true"
/>
</LinearLayout>
Also you can create a custom view base on the layout above. Have you looked at Creating custom view ?
As I understand it int() is not intended as a 'cast' function for designating data type it's simply being (ab)used here to define the context as an arithmetic one. I've (ab)used (0+$val) in the past to ensure that $val is treated as a number.
This question has been hanging around for a while, but none of the fixes I could find worked for me (having the same issue with ipad), but I managed my own solution which should work for most people I imagine.
Here's my code:
html {
background: url("../images/blahblah.jpg") repeat-y;
min-width: 100%;
background-size: contain;
}
Enjoy!
The script is performed before the DOM of the body is built. Put it all into a function and call it from the onload
of the body-element.
Use ngStorage
For All Your AngularJS Local Storage Needs. Please note that this is NOT a native part of the Angular JS framework.
ngStorage
contains two services, $localStorage
and $sessionStorage
angular.module('app', [
'ngStorage'
]).controller('Ctrl', function(
$scope,
$localStorage,
$sessionStorage
){});
Check the Demo
Taking this one step further, to save a file to a relative directory, you can use the replace function. Say you have your workbook saved in: c:\property\california\sacramento\workbook.xlsx, use this to move the property to berkley:
workBookPath = Replace(ActiveWorkBook.path, "sacramento", "berkley")
myWorkbook.SaveAs(workBookPath & "\" & "newFileName.xlsx"
Only works if your file structure contains one instance of the text used to replace. YMMV.
The :
is a bitfield. As for !!
, that is logical double negation and so returns 0
for false or 1
for true. And the -
is a minus sign, i.e. arithmetic negation.
It's all just a trick to get the compiler to barf on invalid inputs.
Consider BUILD_BUG_ON_ZERO
. When -!!(e)
evaluates to a negative value, that produces a compile error. Otherwise -!!(e)
evaluates to 0, and a 0 width bitfield has size of 0. And hence the macro evaluates to a size_t
with value 0.
The name is weak in my view because the build in fact fails when the input is not zero.
BUILD_BUG_ON_NULL
is very similar, but yields a pointer rather than an int
.
I encounter similar situation. I would like to have background of the last .item
to be yellow in the elements that look like...
<div class="container">
<div class="item">item 1</div>
<div class="item">item 2</div>
<div class="item">item 3</div>
...
<div class="item">item x</div>
<div class="other">I'm here for some reasons</div>
</div>
I use nth-last-child(2)
to achieve it.
.item:nth-last-child(2) {
background-color: yellow;
}
It strange to me because nth-last-child of item suppose to be the second of the last item but it works and I got the result as I expect. I found this helpful trick from CSS Trick
create a new page php and add this code:
<?php_x000D_
function ch_title($title){_x000D_
$output = ob_get_contents();_x000D_
if ( ob_get_length() > 0) { ob_end_clean(); }_x000D_
$patterns = array("/<title>(.*?)<\/title>/");_x000D_
$replacements = array("<title>$title</title>");_x000D_
$output = preg_replace($patterns, $replacements,$output);_x000D_
echo $output;_x000D_
}_x000D_
?>
_x000D_
in <head>
add code: <?php require 'page.php' ?>
and on each page you call the function ch_title('my title');
"hello world".split.each{|i| i.capitalize!}.join(' ')
It usually happens when Allow Nulls option is unchecked.
Solution:
Try these steps. It worked for me.
I do not want to craft special error handlers for every loop structure in my code so I have a way of finding problem loops using my standard error handler so that I can then write a special error handler for them.
If an error occurs in a loop, I normally want to know about what caused the error rather than just skip over it. To find out about these errors, I write error messages to a log file as many people do. However writing to a log file is dangerous if an error occurs in a loop as the error can be triggered for every time the loop iterates and in my case 80 000 iterations is not uncommon. I have therefore put some code into my error logging function that detects identical errors and skips writing them to the error log.
My standard error handler that is used on every procedure looks like this. It records the error type, procedure the error occurred in and any parameters the procedure received (FileType in this case).
procerr:
Call NewErrorLog(Err.number, Err.Description, "GetOutputFileType", FileType)
Resume exitproc
My error logging function which writes to a table (I am in ms-access) is as follows. It uses static variables to retain the previous values of error data and compare them to current versions. The first error is logged, then the second identical error pushes the application into debug mode if I am the user or if in other user mode, quits the application.
Public Function NewErrorLog(ErrCode As Variant, ErrDesc As Variant, Optional Source As Variant = "", Optional ErrData As Variant = Null) As Boolean
On Error GoTo errLogError
'Records errors from application code
Dim dbs As Database
Dim rst As Recordset
Dim ErrorLogID As Long
Dim StackInfo As String
Dim MustQuit As Boolean
Dim i As Long
Static ErrCodeOld As Long
Static SourceOld As String
Static ErrDataOld As String
'Detects errors that occur in loops and records only the first two.
If Nz(ErrCode, 0) = ErrCodeOld And Nz(Source, "") = SourceOld And Nz(ErrData, "") = ErrDataOld Then
NewErrorLog = True
MsgBox "Error has occured in a loop: " & Nz(ErrCode, 0) & Space(1) & Nz(ErrDesc, "") & ": " & Nz(Source, "") & "[" & Nz(ErrData, "") & "]", vbExclamation, Appname
If Not gDeveloping Then 'Allow debugging
Stop
Exit Function
Else
ErrDesc = "[loop]" & Nz(ErrDesc, "") 'Flag this error as coming from a loop
MsgBox "Error has been logged, now Quiting", vbInformation, Appname
MustQuit = True 'will Quit after error has been logged
End If
Else
'Save current values to static variables
ErrCodeOld = Nz(ErrCode, 0)
SourceOld = Nz(Source, "")
ErrDataOld = Nz(ErrData, "")
End If
'From FMS tools pushstack/popstack - tells me the names of the calling procedures
For i = 1 To UBound(mCallStack)
If Len(mCallStack(i)) > 0 Then StackInfo = StackInfo & "\" & mCallStack(i)
Next
'Open error table
Set dbs = CurrentDb()
Set rst = dbs.OpenRecordset("tbl_ErrLog", dbOpenTable)
'Write the error to the error table
With rst
.AddNew
!ErrSource = Source
!ErrTime = Now()
!ErrCode = ErrCode
!ErrDesc = ErrDesc
!ErrData = ErrData
!StackTrace = StackInfo
.Update
.BookMark = .LastModified
ErrorLogID = !ErrLogID
End With
rst.Close: Set rst = Nothing
dbs.Close: Set dbs = Nothing
DoCmd.Hourglass False
DoCmd.Echo True
DoEvents
If MustQuit = True Then DoCmd.Quit
exitLogError:
Exit Function
errLogError:
MsgBox "An error occured whilst logging the details of another error " & vbNewLine & _
"Send details to Developer: " & Err.number & ", " & Err.Description, vbCritical, "Please e-mail this message to developer"
Resume exitLogError
End Function
Note that an error logger has to be the most bullet proofed function in your application as the application cannot gracefully handle errors in the error logger. For this reason, I use NZ() to make sure that nulls cannot sneak in. Note that I also add [loop] to the second identical error so that I know to look in the loops in the error procedure first.
dump the headers in one file and the payload of the response in a different file

Thanks for the input. Tried the stuff that has been mentioned here and these are the 2 I got to work:
(
select 'OK', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01)
AND TimeStamp>'2009-02-12 18:00:00'
AND (BoolField05=1)
)
UNION
(
select 'DEL', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01)
AND TimeStamp>'2009-02-12 18:00:00'
AND NOT (BoolField05=1)
)
AND
select
case
when
(BoolField05=1)
then 'OK'
else 'DEL'
end,
*
from WorkItems t1
Where
exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01)
AND TimeStamp>'2009-02-12 18:00:00'
Which would be the most efficient of these (edit: the second as it only scans the table once), and is it possible to make it even more efficient? (The BoolField=1) is really a variable (dyn sql) that can contain any where statement on the table.
I am running on MS SQL 2005. Tried Quassnoi examples but did not work as expected.
According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.
It could be something like that:
var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];
var arrays = [], size = 3;
while (a.length > 0)
arrays.push(a.splice(0, size));
console.log(arrays);

Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:
myDate : Date;
This works fine with ./self.sh
, ~/self.sh
, source self.sh
, source ~/self.sh
:
#!/usr/bin/env bash
self=$(readlink -f "${BASH_SOURCE[0]}")
basename=$(basename "$self")
echo "$self"
echo "$basename"

There are several problems.
One is of style; always capitalize class names. This is a universally observed Java convention. Failing to do so confuses other programmers.
Secondly, the line
System.out.println(boolean isLeapYear);
is a syntax error. Delete it.
Thirdly.
You never call the function from your main routine. That is why you never see any reply to the input.
Was following one of training with Spring webmvc 4.2.3, while I'm using Spring webmvc 5.2.3 they suggested to create a form
<form:form modelAttribute="aNewAccount" method="get" action="/accountCreated">
that was causing the "disclose" error.
Altered as below to make it work. Looks like method above was the culprit.
<form:form modelAttribute="aNewAccount" action="accountCreated.html">
in fact, exploring further, method="post" in form annotation would work if properly declared:
@RequestMapping(value="/accountCreated", method=RequestMethod.POST)
The error probably gives more information like this (although your jar names could be different)

Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:
using System;
using System.IO;
using System.Text;
class Program {
static void Main(string[] args) {
// Read the file into <bits>
var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
var len = (int)fs.Length;
var bits = new byte[len];
fs.Read(bits, 0, len);
// Dump 16 bytes per line
for (int ix = 0; ix < len; ix += 16) {
var cnt = Math.Min(16, len - ix);
var line = new byte[cnt];
Array.Copy(bits, ix, line, 0, cnt);
// Write address + hex + ascii
Console.Write("{0:X6} ", ix);
Console.Write(BitConverter.ToString(line));
Console.Write(" ");
// Convert non-ascii characters to .
for (int jx = 0; jx < cnt; ++jx)
if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
Console.WriteLine(Encoding.ASCII.GetString(line));
}
Console.ReadLine();
}
}
in appsetting.json
{ "DebugMode": false, "Urls": "http://localhost:8082" }
If you are using jQuery, this could be a simple solution:
<script>
var el = $("#element");
var position = el.position();
console.log( "left: " + position.left + ", top: " + position.top );
</script>

The built JAR file is located at target/<YourProjectAndVersion>-pkg.jar
after you run mvn package
. All of its compile-time and runtime dependencies will be included in the lib/
folder inside the JAR file.

Going off of tbradley22's answer, but using .map
instead:
var a = ["car", "bike", "scooter"];
a.map(function(entry) {
var singleObj = {};
singleObj['type'] = 'vehicle';
singleObj['value'] = entry;
return singleObj;
});
You manage the list of available compilers in the Window -> Preferences -> Java -> Installed JRE's tab
.
In the project build path configuration dialog, under the libraries tab, you can delete the entry for JRE System Library
, click on Add Library
and choose the installed JRE to compile with. Some compilers can be configured to compile at a back-level compiler version. I think that's why you're seeing the addition version options.
Simply put, casting is more efficient than creating a Double object.
Without For loop:
Dim newColumn As New Data.DataColumn("Foo", GetType(System.String))
newColumn.DefaultValue = "Your DropDownList value"
table.Columns.Add(newColumn)
C#:
System.Data.DataColumn newColumn = new System.Data.DataColumn("Foo", typeof(System.String));
newColumn.DefaultValue = "Your DropDownList value";
table.Columns.Add(newColumn);
Here is another way using list comprehension (some people might find it debatable). It is very approachable for simple tests, e.g. comparisons on object attributes (which I need a lot):
el = [x for x in mylist if x.attr == "foo"][0]
Of course this assumes the existence (and, actually, uniqueness) of a suitable element in the list.
Add poster="placeholder.png"
to the video tag.
<video width="470" height="255" poster="placeholder.png" controls>
<source src="video.mp4" type="video/mp4">
<source src="video.ogg" type="video/ogg">
<source src="video.webm" type="video/webm">
<object data="video.mp4" width="470" height="255">
<embed src="video.swf" width="470" height="255">
</object>
</video>
Does that work?
The fact that Clang compiles code faster may not be as important as the speed of the resulting binary. However, here is a series of benchmarks.
--force-reinstall
doesn't appear to force reinstall using python2.7 with pip-1.5
I've had to use
--no-deps --ignore-installed
you can search in registry.Actually I do'nt have vs2012 but I have vs2010.
There are 3 different (but very similar) registry keys for each of the 3 platform packages. Each key has a DWORD value called “Installed” with a value of 1.
HKLM\SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\x86
HKLM\SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\x64
HKLM\SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\ia64
You can use registry function for that......
You can find more about it in the bundler website (emphasis added below for your convenience):
After developing your application for a while, check in the application together with the Gemfile and Gemfile.lock snapshot. Now, your repository has a record of the exact versions of all of the gems that you used the last time you know for sure that the application worked...
This is important: the Gemfile.lock makes your application a single package of both your own code and the third-party code it ran the last time you know for sure that everything worked. Specifying exact versions of the third-party code you depend on in your Gemfile would not provide the same guarantee, because gems usually declare a range of versions for their dependencies.
in my experience. I was using jsp for web. at that time I use mysql 5 and mysql connecter jar 8. So due to the version problem I face this kind of problem. I solve by replace the mysql connector jar file the exact version mysql.
I am using Laravel 5.4 and response()->file('path/to/file.ext')
to open e.g. a pdf in inline-mode in browsers. This works quite well, but when a user wants to save the file, the save-dialog suggests the last part of the url as filename.
I already tried adding a headers-array like mentioned in the Laravel-docs, but this doesn't seem to override the header set by the file()-method:
return response()->file('path/to/file.ext', [
'Content-Disposition' => 'inline; filename="'. $fileNameFromDb .'"'
]);
This is quite an old question but there's a much simple way of achieving this.
myButton.userInteractionEnabled = false
This will only disable any touch gestures without changing the appearance of the button
You can also prompt for a password without setting a variable in the current shell by doing something like this:
$(read -s;echo $REPLY)
For instance:
my-command --set password=$(read -sp "Password: ";echo $REPLY)
You can add several of these prompted values with line break, doing this:
my-command --set user=$(read -sp "`echo $'\n '`User: ";echo $REPLY) --set password=$(read -sp "`echo $'\n '`Password: ";echo $REPLY)
Ensure two things in the AVD manager utility for the emulator:
SD Card size is mentioned e.g. 512.
From the Hardware tag, press New and select "SD Card Support" from the drop down menu.
Now, start the emulator. SD Card shall now support writing as well.
A single way to remove sessions is setting it to null;
Session["your_session"] = null;
You need to use isset() to check whether value is set.
Go inside bin folder in C drive where Postgres is installed. run following command in git bash or Command prompt:
pg_ctl.exe restart -D "<path upto data>"
Ex:
pg_ctl.exe restart -D "C:\Program Files\PostgreSQL\9.6\data"
Another way: type "services.msc" in run popup(windows + R). This will show all services running Select Postgres service from list and click on start/stop/restart.
Thanks
You should group by the field you want the SUM apply to, and not include in SELECT any field other than multiple rows values, like COUNT, SUM, AVE, etc, because if you include Bill field like in this case, only the first value in the set of rows will be displayed, being almost meaningless and confusing.
This will return the sum of bills per account number:
SELECT SUM(Bill) FROM Table1 GROUP BY AccountNumber
You could add more clauses like WHERE, ORDER BY etc as needed.
Here is the code of ReadDoc/docx.java: This will read a dox/docx file and print its content to the console. you can customize it your way.

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false
:
Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.
For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.
Here are a couple basic examples to get started quick and dirty.
Set variable:
SET(INSTALL_ETC_DIR "etc")
Use variable:
SET(INSTALL_ETC_CROND_DIR "${INSTALL_ETC_DIR}/cron.d")
Set variable:
SET(PROGRAM_SRCS
program.c
program_utils.c
a_lib.c
b_lib.c
config.c
)
Use variable:
add_executable(program "${PROGRAM_SRCS}")
Instance methods need to be called from an instance. Your setLoanItem
method is an instance method (it doesn't have the modifier static
), which it needs to be in order to function (because it is setting a value on the instance that it's called on (this
)).
You need to create an instance of the class before you can call the method on it:
Media media = new Media();
media.setLoanItem("Yes");
(Btw it would be better to use a boolean instead of a string containing "Yes".)
in my case, I declared one static variable in .h file, like
//myClass.h
class myClass
{
static int m_nMyVar;
static void myFunc();
}
and in myClass.cpp, I tried to use this m_nMyVar. It got LINK error like:
error LNK2001: unresolved external symbol "public: static class... The link error related cpp file looks like:
//myClass.cpp
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}
So I add below code on the top of myClass.cpp
//myClass.cpp
int myClass::m_nMyVar; //it seems redefine m_nMyVar, but it works well
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}
then LNK2001 is gone.
Compile the program with:
g++ -Wall -Wextra -Werror -c main.cpp -o main.o
^^^^^^^^^^^^^^^^^^^^ <- For listing all warnings when your code is compiled.
as cout
is present in the C++ standard library, which would need explicit linking with -lstdc++
when using gcc
; g++
links the standard library by default.
With gcc
, (g++
should be preferred over gcc
)
gcc main.cpp -lstdc++ -o main.o
Yes, there's a command git commit --amend
which is used to "fix" last commit.
In your case it would be called as:
git add the_left_out_file
git commit --amend --no-edit
The --no-edit flag allow to make amendment to commit without changing commit message.
EDIT: Warning You should never amend public commits, that you already pushed to public repository, because what amend does is actually removing from history last commit and creating new commit with combined changes from that commit and new added when amending.
If you are working in PHP version 5.* then you have to install
sudo apt-get install php5-gd
And if you are working in PHP version 7.* then you have to install
sudo apt-get install php7.0-gd
Hope it will work...
And if you are working in PHP version 7.2 then you have to install
sudo apt-get install php7.2-gd... it worked for me
Note that dnx
has a different cache for feeding HTTP results:
Microsoft .NET Development Utility Clr-x86-1.0.0-rc1-16231
CACHE https://www.nuget.org/api/v2/
CACHE http://192.168.148.21/api/odata/
Which you can clear with
dnu clear-http-cache
Now we just need to find out what the command will be on the new dotnet
CLI tool.
...and here it is:
dotnet restore --no-cache
Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:
<script type="text/javascript"> $(function() { //jQuery trick to say after all the HTML is parsed. $("input[type=radio]").click(function() { var total = 0; $("input[type=radio]:checked").each(function() { total += parseFloat($(this).val()); }); $("#totalSum").val(total); }); }); </script>
EDIT: This code works for me
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body> <strong>Choose a base package:</strong> <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942 <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313 <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829 <strong>Choose an add on:</strong> <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0 <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146) <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455) <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764) <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073) <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382) <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691) <strong>Your total is:</strong> <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <script type="text/javascript"> $("input[type=radio]").click(function() { var total = 0; $("input[type=radio]:checked").each(function() { total += parseFloat($(this).val()); }); $("#totalSum").val(total); }); </script> </body> </html>
To Milan Babuškov, IMO, this is exactly what the replacement function should look like :-)

Unless I am misunderstanding what you are asking you can do this on the properties for your data grid view. You need to set the Anchor property to the sides you want it locked to.
get page content by page name:
<?php
$page = get_page_by_title( 'page-name' );
$content = apply_filters('the_content', $page->post_content);
echo $content;
?>
For what was actually asked, my approach is to put those if
s inside a one-looped loop
while (True):
if (some_condition):
...
if (condition_a):
# do something
# and then exit the outer if block
break
...
if (condition_b):
# do something
# and then exit the outer if block
break
# more code here
# make sure it is looped once
break
Test it:
conditions = [True,False]
some_condition = True
for condition_a in conditions:
for condition_b in conditions:
print("\n")
print("with condition_a", condition_a)
print("with condition_b", condition_b)
while (True):
if (some_condition):
print("checkpoint 1")
if (condition_a):
# do something
# and then exit the outer if block
print("checkpoint 2")
break
print ("checkpoint 3")
if (condition_b):
# do something
# and then exit the outer if block
print("checkpoint 4")
break
print ("checkpoint 5")
# more code here
# make sure it is looped once
break
This worked for me . In my case 2 tables foo and boo have to be joined based on 3 different columns.Please note in my case ,in boo the 3 common columns are not primary key
i.e., one to one mapping based on 3 different columns
@Entity
@Table(name = "foo")
public class foo implements Serializable
{
@Column(name="foocol1")
private String foocol1;
//add getter setter
@Column(name="foocol2")
private String foocol2;
//add getter setter
@Column(name="foocol3")
private String foocol3;
//add getter setter
private Boo boo;
private int id;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "brsitem_id", updatable = false)
public int getId()
{
return this.id;
}
public void setId(int id)
{
this.id = id;
}
@OneToOne
@JoinColumns(
{
@JoinColumn(updatable=false,insertable=false, name="foocol1", referencedColumnName="boocol1"),
@JoinColumn(updatable=false,insertable=false, name="foocol2", referencedColumnName="boocol2"),
@JoinColumn(updatable=false,insertable=false, name="foocol3", referencedColumnName="boocol3")
}
)
public Boo getBoo()
{
return boo;
}
public void setBoo(Boo boo)
{
this.boo = boo;
}
}
@Entity
@Table(name = "boo")
public class Boo implements Serializable
{
private int id;
@Column(name="boocol1")
private String boocol1;
//add getter setter
@Column(name="boocol2")
private String boocol2;
//add getter setter
@Column(name="boocol3")
private String boocol3;
//add getter setter
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "item_id", updatable = false)
public int getId()
{
return id;
}
public void setId(int id)
{
this.id = id;
}
}
<div style='width:200px;margin:0 auto;> sometext or image tag</div>
this works horizontally
This function should do what you want:
char* readLine( FILE* file )
{
char buffer[1024];
char* result = 0;
int length = 0;
while( !feof(file) )
{
fgets( buffer, sizeof(buffer), file );
int len = strlen(buffer);
buffer[len] = 0;
length += len;
char* tmp = (char*)malloc(length+1);
tmp[0] = 0;
if( result )
{
strcpy( tmp, result );
free( result );
result = tmp;
}
strcat( result, buffer );
if( strstr( buffer, "\n" ) break;
}
return result;
}
char* line = readLine( stdin );
/* Use it */
free( line );
I hope this helps.
I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.
<ComboBox ItemsSource="{Binding SalesPeriods}"
SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />
Perhaps you have some very weird and restrictive SELinux rules in place?
If not, try strace -o /tmp/wtf -fF curl -v google.com
and try to spot from /tmp/wtf
output file what's going on.
If you're running Mac, as @pedro mentions ensure you have the HAXM installer dowloaded via the Android SDK Manager.
Next install it! In finder navigate to /YOUR_SDK_PATH/extras/intel/Hardware_Accelerated_Execution_Manager/
Run and install the .mpgk in the following .dmg
IntelHAXM_1.1.0_for_10.10.dmg
IntelHAXM_1.1.0_below_10.10.dmg
Example:
$cd /YOUR_SDK_PATH/extras/intel/Hardware_Accelerated_Execution_Manager/ $open IntelHAXM_1.1.0_below_10.10.dmg
For new browsers: Object.keys( MY_DICTIONARY )
will return an array of keys. Else you may want to go the old school way:
var keys = []
for(var key in dic) keys.push( key );
This is how I did it on macOS:
vim ~/.bash_profile # macOS 10.14 Mojave and older
vim ~/.zshrc # macOS 10.15 Catalina and newer (using zsh by default)
And added the following environment variables:
export ANDROID_HOME=/Users/{{your user}}/Library/Android/sdk
export ANDROID_SDK_ROOT=/Users/{{your user}}/Library/Android/sdk
export ANDROID_AVD_HOME=/Users/{{your user}}/.android/avd
Android path might be different, if so change it accordingly. At last, to refresh the terminal to apply changes:
source ~/.bash_profile # macOS 10.14 Mojave and older
source ~/.zshrc # macOS 10.15 Catalina and newer (using zsh by default)
This is very late, but I just wanted to add that there is a more elegant way: using reversed
for i in reversed(range(10)):
print i
gives:
4
3
2

I think the fastest way is to use grid system with fractions. So your container have 100vw, which is 100% of the window width and 100vh which is 100% of the window height.
Using fractions or 'fr' you can choose the width you like. the sum of the fractions equals to 100%, in this example 4fr. So the first part will be 1fr (25%) and the seconf is 3fr (75%)
More about fr units here.
.container{
width: 100vw;
height:100vh;
display: grid;
grid-template-columns: 1fr 3fr;
}
/*You don't need this*/
.div1{
background-color: yellow;
}
.div2{
background-color: red;
}
_x000D_
<div class='container'>
<div class='div1'>This is div 1</div>
<div class='div2'>This is div 2</div>
</div>
_x000D_
I'd suggest that it is better practice to use String.format()
. The main reason is that String.format()
can be more easily localised with text loaded from resource files whereas concatenation can't be localised without producing a new executable with different code for each language.
If you plan on your app being localisable you should also get into the habit of specifying argument positions for your format tokens as well:
"Hello %1$s the time is %2$t"
This can then be localised and have the name and time tokens swapped without requiring a recompile of the executable to account for the different ordering. With argument positions you can also re-use the same argument without passing it into the function twice:
String.format("Hello %1$s, your name is %1$s and the time is %2$t", name, time)
You can use the below code for it.
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
Based on Jim Lim's answer, I installed the GitHub Markdown gem. That included a script called gfm that takes a filename on the command line and writes the equivalent HTML to standard output. I modified that slightly to save the file to disk and then to open the standard browser with launchy:
#!/usr/bin/env ruby
HELP = <<-help
Usage: gfm [--readme | --plaintext] [<file>]
Convert a GitHub-Flavored Markdown file to HTML and write to standard output.
With no <file> or when <file> is '-', read Markdown source text from standard input.
With `--readme`, the files are parsed like README.md files in GitHub.com. By default,
the files are parsed with all the GFM extensions.

Above code has been deprecated in API level 30. Now you can get using following code
val width = windowManager.currentWindowMetrics.bounds.width()
val height = windowManager.currentWindowMetrics.bounds.height()
This method reports the window size including all system bar areas, while Display#getSize(Point)
reports the area excluding navigation bars and display cutout areas. The value reported by Display#getSize(Point)
can be obtained by using:
val metrics = windowManager.currentWindowMetrics
// Gets all excluding insets
val windowInsets = metrics.windowInsets
var insets: Insets = windowInsets.getInsets(WindowInsets.Type.navigationBars())
val cutout = windowInsets.displayCutout
if (cutout != null) {
val cutoutSafeInsets = Insets.of(cutout.safeInsetLeft, cutout.safeInsetTop, cutout.safeInsetRight, cutout.safeInsetBottom)
insets = Insets.max(insets, cutoutSafeInsets)
}
val insetsWidth = insets.right + insets.left
val insetsHeight = insets.top + insets.bottom
// Legacy size that Display#getSize reports
val legacySize = Size(metrics.bounds.width() - insetsWidth, metrics.bounds.height() - insetsHeight)
Here's a function that doesn't require any packages to be installed. You give it a Date
object (or a character
that it can convert into a Date
), and it adds n
months to that date without changing the day of the month (unless the month you land on doesn't have enough days in it, in which case it defaults to the last day of the returned month). Just in case it doesn't make sense reading it, there are some examples below.
addMonth <- function(date, n = 1){
if (n == 0){return(date)}
if (n %% 1 != 0){stop("Input Error: argument 'n' must be an integer.")}
# Check to make sure we have a standard Date format
if (class(date) == "character"){date = as.Date(date)}
# Turn the year, month, and day into numbers so we can play with them
y = as.numeric(substr(as.character(date),1,4))
m = as.numeric(substr(as.character(date),6,7))
d = as.numeric(substr(as.character(date),9,10))
# Run through the computation
i = 0
# Adding months
if (n > 0){
while (i < n){
m = m + 1
if (m == 13){
m = 1
y = y + 1
}
i = i + 1
}
}
# Subtracting months
else if (n < 0){
while (i > n){
m = m - 1
if (m == 0){
m = 12
y = y - 1
}
i = i - 1
}
}
# If past 28th day in base month, make adjustments for February
if (d > 28 & m == 2){
# If it's a leap year, return the 29th day
if ((y %% 4 == 0 & y %% 100 != 0) | y %% 400 == 0){d = 29}
# Otherwise, return the 28th day
else{d = 28}
}
# If 31st day in base month but only 30 days in end month, return 30th day
else if (d == 31){if (m %in% c(1, 3, 5, 7, 8, 10, 12) == FALSE){d = 30}}
# Turn year, month, and day into strings and put them together to make a Date
y = as.character(y)
# If month is single digit, add a leading 0, otherwise leave it alone
if (m < 10){m = paste('0', as.character(m), sep = '')}
else{m = as.character(m)}
# If day is single digit, add a leading 0, otherwise leave it alone
if (d < 10){d = paste('0', as.character(d), sep = '')}
else{d = as.character(d)}
# Put them together and convert return the result as a Date

If you want to split a string into words, you can use explode() or str_word_count().
To help understand why this surprising behavior isn't entirely terrible, consider an application which accepts a config file name as an argument:
config_root = "/etc/myapp.conf/"
file_name = os.path.join(config_root, sys.argv[1])
If the application is executed with:
$ myapp foo.conf
The config file /etc/myapp.conf/foo.conf
will be used.
But consider what happens if the application is called with:
$ myapp /some/path/bar.conf
Then myapp
should use the config file at /some/path/bar.conf
(and not /etc/myapp.conf/some/path/bar.conf
or similar).
It may not be great, but I believe this is the motivation for the absolute path behaviour.
Try the net use command
I've found this method to be useful when working with transitions
$element[0].style.display = 'table';
$element[0].offsetWidth; // force reflow
$element.one($.support.transition.end, function () {
$element[0].style.display = 'block';
});
I think this confusing exception occurs when you use a variable in a lambda which is a null-reference at run-time. In your case, I would check if your variable calculationViewModel is a null-reference.
Something like:
public ActionResult MNPurchase()
{
CalculationViewModel calculationViewModel = (CalculationViewModel)TempData["calculationViewModel"];
if (calculationViewModel != null)
{
decimal OP = landTitleUnitOfWork.Sales.Find()
.Where(x => x.Min >= calculationViewModel.SalesPrice)
.FirstOrDefault()
.OP;
decimal MP = landTitleUnitOfWork.Sales.Find()
.Where(x => x.Min >= calculationViewModel.MortgageAmount)
.FirstOrDefault()
.MP;
calculationViewModel.LoanAmount = (OP + 100) - MP;
calculationViewModel.LendersTitleInsurance = (calculationViewModel.LoanAmount + 850);
return View(calculationViewModel);
}
else
{
// Do something else...
}
}
After you've retrieved the reflect.Value
of the field by using Field(i)
you can get a
interface value from it by calling Interface()
. Said interface value then represents the
value of the field.
There is no function to convert the value of the field to a concrete type as there are,
as you may know, no generics in go. Thus, there is no function with the signature GetValue() T
with T
being the type of that field (which changes of course, depending on the field).
The closest you can achieve in go is GetValue() interface{}
and this is exactly what reflect.Value.Interface()
offers.
The following code illustrates how to get the values of each exported field in a struct using reflection (play):
import (
"fmt"
"reflect"
)
func main() {
x := struct{Foo string; Bar int }{"foo", 2}
v := reflect.ValueOf(x)
values := make([]interface{}, v.NumField())
for i := 0; i < v.NumField(); i++ {
values[i] = v.Field(i).Interface()
}
fmt.Println(values)
}
I would like to extend the answer of @dzintars about the Cygwin version of pkg-config in that focus how should one use it properly with CMake, because I see various comments about CMake in this topic.
I have experienced many troubles with CMake + Cygwin's pkg-config and I want to share my experience how to avoid them.
1. The symlink C:/Cygwin64/bin/pkg-config -> pkgconf.exe does not work in Windows console.
It is not a native Windows .lnk symlink and it won't be callable in Windows console cmd.exe even if you add ".;" to your %PATHEXT% (see https://www.mail-archive.com/[email protected]/msg104088.html).
It won't work from CMake, because CMake calls pkg-config with the method execute_process() (FindPkgConfig.cmake) which opens a new cmd.exe.
Solution: Add -DPKG_CONFIG_EXECUTABLE=C:/Cygwin64/bin/pkgconf.exe to the CMake command line (or set it in CMakeLists.txt).
2. Cygwin's pkg-config recognizes only Cygwin paths in PKG_CONFIG_PATH (no Windows paths).
For example, on my system the .pc files are located in C:\Cygwin64\usr\x86_64-w64-mingw32\sys-root\mingw\lib\pkgconfig. The following three paths are valid, but only path C works in PKG_CONFIG_PATH:
Solution: add .pc files location always as a Cygwin path into PKG_CONFIG_PATH.
3) CMake converts forward slashes to backslashes in PKG_CONFIG_PATH on Cygwin.
It happens due to the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21629. It prevents using the workaround described in [2].
Solution: manually update the function _pkg_set_path_internal() in the file C:/Program Files/CMake/share/cmake-3.x/Modules/FindPkgConfig.cmake. Comment/remove the line:
file(TO_NATIVE_PATH "${_pkgconfig_path}" _pkgconfig_path)
4) CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH have no effect on pkg-config in Cygwin.
Reason: the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21775.
Solution: Use only PKG_CONFIG_PATH as an environment variable if you run CMake builds on Cygwin. Forget about CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH.
This is not a question about make, it is a question about the semantic of the #include
directive.
The problem is, that there is no file at the path "../StdCUtil/StdCUtil/split.h". This is the path that results when the compiler combines the include path "../StdCUtil" with the relative path from the #include
directive "StdCUtil/split.h".
To fix this, just use -I..
instead of -I../StdCUtil
.

I would use a UIAlertView
with a UITextField
subview. You can either add the text field manually or, in iOS 5, use one of the new methods.
Try like this...
<script>
function getPaging(str) {
$("#loading-content").load("dataSearch.php?"+str, hideLoader);
}
</script>
<li onclick="getPaging(this.id)" id="1">1</li>
<li onclick="getPaging(this.id)" id="2">2</li>
or unobtrusively
$(function() {
$("li").on("click",function() {
showLoader();
$("#loading-content").load("dataSearch.php?"+this.id, hideLoader);
});
});
using just
<li id="1">1</li>
<li id="2">2</li>
I'm not 100% on why (actually came here to search for the answer), but this also works, and doesn't require replacing all nan values.
import pandas as pd
import numpy as np
df = pd.DataFrame([["foo1"], ["foo2"], ["bar"], [np.nan]], columns=['a'])
newdf = df.loc[df['a'].str.contains('foo') == True]
Works with or without .loc
.
I have no idea why this works, as I understand it when you're indexing with brackets pandas evaluates whatever's inside the bracket as either True
or False
. I can't tell why making the phrase inside the brackets 'extra boolean' has any effect at all.
