import yaml
data = dict(
A = 'a',
B = dict(
C = 'c',
D = 'd',
E = 'e',
)
)
with open('data.yml', 'w') as outfile:
yaml.dump(data, outfile, default_flow_style=False)
The default_flow_style=False
parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:
A: a
B: {C: c, D: d, E: e}
"There should be one -- and preferably only one -- obvious way to do it." So let me add another one. This one is more like "install from sources" for Debian/Ubuntu, from https://github.com/yaml/pyyaml
Install the libYAML and it's headers:
sudo apt-get install libyaml-dev
Download the pyyaml sources:
wget http://pyyaml.org/download/pyyaml/PyYAML-3.13.tar.gz
Install from sources, (don't forget to activate your venv):
. your/env/bin/activate
tar xzf PyYAML-3.13.tar.gz
cd PyYAML-3.13.tar.gz
(env)$ python setup.py install
(env)$ python setup.py test
It's better to use $(window).scroll()
rather than $('#Eframe').on("mousewheel")
$('#Eframe').on("mousewheel")
will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.
$(window).scroll(function(){
var scrollPos = $(document).scrollTop();
console.log(scrollPos);
});
If #Eframe
is an element with overflow:scroll
on it and you want it's scroll position. I think this should work (I haven't tested it though).
$('#Eframe').scroll(function(){
var scrollPos = $('#Eframe').scrollTop();
console.log(scrollPos);
});
I got the answer to my own question, ant this is:
select reverse(stuff(reverse('a,b,c,d,'), 1, N, ''))
Where N is the number of characters to remove. This avoids to write the complex column/string twice
<graphics.h>
is very old library. It's better to use something that is new
Here are some 2D libraries (platform independent) for C/C++
Also there is a free very powerful 3D open source graphics library for C++
The first and third ways are the same: they evaluate an array in scalar context. I would consider this to be the standard way to get an array's size.
The second way actually returns the last index of the array, which is not (usually) the same as the array size.
It is better to define our own process to for upgrade.
Android & iOS : If latest app version available then it will show alert as “Latest version available with more features, To upgrade click on upgrade button” (Alert with “Upgarde” and “No. Thanks” button.) Then app will redirect to playstore/Appstore and it will open latest version.
--- we can do upgrade compulsory or optionally.
Before Upgrade process please make sure that you handled proper db migration process if there is any db schema change.
Similar question here.
With Entity Framework there is EntityFramework-Plus (extensions library).
Available on NuGet. Then you can write something like:
// DELETE all users which has been inactive for 2 years
ctx.Users.Where(x => x.LastLoginDate < DateTime.Now.AddYears(-2))
.Delete();
It is also useful for bulk deletes.
You can disable expandtab option from within Vim as below:
:set expandtab!
or
:set noet
PS: And set it back when you are done with inserting tab, with "set expandtab" or "set et"
PS: If you have tab set equivalent to 4 spaces in .vimrc (softtabstop), you may also like to set it to 8 spaces in order to be able to insert a tab by pressing tab key once instead of twice (set softtabstop=8).
If you want to have control over this you need to implement the [IEquatable interface][1]
[1]: http://This method determines equality by using the default equality comparer, as defined by the object's implementation of the IEquatable.Equals method for T (the type of values in the list).
SELECT *, CONVERT( UNCOMPRESS(column) USING "utf8" ) AS column FROM table_name
- First to me Iterating
and Looping
are 2 different things.
Eg: Increment a variable till 5 is Looping.
int count = 0;
for (int i=0 ; i<5 ; i++){
count = count + 1;
}
Eg: Iterate over the Array to print out its values, is about Iteration
int[] arr = {5,10,15,20,25};
for (int i=0 ; i<arr.length ; i++){
System.out.println(arr[i]);
}
Now about all the Loops:
- Its always better to use For-Loop when you know the exact nos of time you gonna Loop, and if you are not sure of it go for While-Loop. Yes out there many geniuses can say that it can be done gracefully with both of them and i don't deny with them...but these are few things which makes me execute my program flawlessly...
For Loop
:
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("The sum is " + sum);
The Difference between While and Do-While is as Follows :
- While
is a Entry Control Loop
, Condition is checked in the Beginning before entering the loop.
- Do-While
is a Exit Control Loop
, Atleast once the block is always executed then the Condition is checked.
While Loop
:
int sum = 0;
int i = 0; // i is 0 Here
while (i<100) {
sum += i;
i++;
}
System.out.println("The sum is " + sum);
do-While
:
int sum = 0;
int i = 0; // i is 0 Here
do{
sum += i;
i++
}while(i < 100; );
System.out.println("The sum is " + sum);
From Java 5 we also have For-Each Loop to iterate over the Collections, even its handy with Arrays.
ArrayList<String> arr = new ArrayList<String>();
arr.add("Vivek");
arr.add("Is");
arr.add("Good");
arr.add("Boy");
for (String str : arr){ // str represents the value in each index of arr
System.out.println(str);
}
I tried use [disabled]="!editmode"
but it not work in my case.
This is my solution [disabled]="!editmode ? 'disabled': null"
, I share for whom concern.
<button [disabled]="!editmode ? 'disabled': null"
(click)='loadChart()'>
<div class="btn-primary">Load Chart</div>
</button>
The two functions below I have found to be very useful when dealing with many variable testing cases.
def nz(value, none_value, strict=True):
''' This function is named after an old VBA function. It returns a default
value if the passed in value is None. If strict is False it will
treat an empty string as None as well.
example:
x = None
nz(x,"hello")
--> "hello"
nz(x,"")
--> ""
y = ""
nz(y,"hello")
--> ""
nz(y,"hello", False)
--> "hello" '''
if value is None and strict:
return_val = none_value
elif strict and value is not None:
return_val = value
elif not strict and not is_not_null(value):
return_val = none_value
else:
return_val = value
return return_val
def is_not_null(value):
''' test for None and empty string '''
return value is not None and len(str(value)) > 0
To update an entity with Entity Framework Core, this is the logical process:
DbContext
classUpdate()
method in DbContext
:
Begins tracking the given entity in the Modified state such that it will be updated in the database when
SaveChanges()
is called.
Update method doesn't save changes in database; instead, it sets states for entries in DbContext instance.
So, We can invoke Update()
method before to save changes in database.
I'll assume some object definitions to answer your question:
Database name is Store
Table name is Product
Product class definition:
public class Product
{
public int? ProductID { get; set; }
public string ProductName { get; set; }
public string Description { get; set; }
public decimal? UnitPrice { get; set; }
}
DbContext class definition:
public class StoreDbContext : DbContext
{
public DbSet<Product> Products { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer("Your Connection String");
base.OnConfiguring(optionsBuilder);
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Order>(entity =>
{
// Set key for entity
entity.HasKey(p => p.ProductID);
});
base.OnModelCreating(modelBuilder);
}
}
Logic to update entity:
using (var context = new StoreDbContext())
{
// Retrieve entity by id
// Answer for question #1
var entity = context.Products.FirstOrDefault(item => item.ProductID == id);
// Validate entity is not null
if (entity != null)
{
// Answer for question #2
// Make changes on entity
entity.UnitPrice = 49.99m;
entity.Description = "Collector's edition";
/* If the entry is being tracked, then invoking update API is not needed.
The API only needs to be invoked if the entry was not tracked.
https://www.learnentityframeworkcore.com/dbcontext/modifying-data */
// context.Products.Update(entity);
// Save changes in database
context.SaveChanges();
}
}
Here is a base R one liner that overlaps a number of previous solutions, but returns a data.frame with the proper names.
out <- setNames(data.frame(before$attr,
do.call(rbind, strsplit(as.character(before$type),
split="_and_"))),
c("attr", paste0("type_", 1:2)))
out
attr type_1 type_2
1 1 foo bar
2 30 foo bar_2
3 4 foo bar
4 6 foo bar_2
It uses strsplit
to break up the variable, and data.frame
with do.call
/rbind
to put the data back into a data.frame. The additional incremental improvement is the use of setNames
to add variable names to the data.frame.
Add below code to following files.
app.component.ts
<input type="text" [(ngModel)]="fname" >
{{fname}}
export class appcomponent {
fname:any;
}
app.module.ts
import {FormsModule} from '@angular/forms';
@NgModule({
imports: [ BrowserModule,FormsModule ],
declarations: [ AppComponent],
bootstrap: [ AppComponent ]
})
Hope this helps
How about this.. used a string instead of list, but same thing.. string can be treated like a list in Python:
def comb(s, res):
if not s: return
res.add(s)
for i in range(0, len(s)):
t = s[0:i] + s[i + 1:]
comb(t, res)
res = set()
comb('game', res)
print(res)
The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.
You will then need to specify which configuration you want to use when updating the databases.
Update-Database -ConfigurationTypeName MyRenamedConfiguration
$(".datepicker").datepicker({maxDate: '0'});
This will set the maxDate to +0 days from the current date (i.e. today). See:
I ended up here after struggling for a while, but actually what I was missing was just:
If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.

You also get this error if you do not create and populate your tables in the right order. For example, according to your schema, Comments table needs user_id
, project_id
, task_id
and data_type_id
. This means that Users
table, Projects
table, Task
table and Data_Type
table must already have exited and have values in them before you can reference their ids or any other column.
In Laravel this would mean calling your database seeders in the right order:
class DatabaseSeeder extends Seeder
{
/**
* Seed the application's database.
*
* @return void
*/
public function run()
{
$this->call(UserSeeder::class);
$this->call(ProjectSeeder::class);
$this->call(TaskSeeder::class);
$this->call(DataTypeSeeder::class);
$this->call(CommentSeeder::class);
}
}
This was how I solved a similar issue.
Try something like:
var store = new UserStore<ApplicationUser>(new ApplicationDbContext());
var userManager = new UserManager<ApplicationUser>(store);
ApplicationUser user = userManager.FindByNameAsync(User.Identity.Name).Result;
Works with RTM.
Children inherit opacity. It'd be weird and inconvenient if they didn't.
You can use a translucent PNG file for your background image, or use an RGBa (a for alpha) color for your background color.
Example, 50% faded black background:
<div style="background-color:rgba(0, 0, 0, 0.5);">_x000D_
<div>_x000D_
Text added._x000D_
</div>_x000D_
</div>
_x000D_
UPDATE: Android SDK 11 added a recreate()
method to activities.
I've done that by simply reusing the intent that started the activity. Define an intent starterIntent
in your class and assign it in onCreate()
using starterIntent = getIntent();
. Then when you want to restart the activity, call finish(); startActivity(starterIntent);
It isn't a very elegant solution, but it's a simple way to restart your activity and force it to reload everything.
Using file
command with the --mime-encoding
option (e.g. file --mime-encoding some_file.txt
) instead of the -I option works on OS X and has the added benefit of omitting the mime type, "text/plain", which you probably don't care about.

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.
The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)
For razor you can use: culture, value
@String.Format(new CultureInfo("sv-SE"), @Model.value)
I know it has been a while since this was asked, but I learned an alternative yesterday
We all know you can do:
if(o instanceof String) { // etc
but what if you dont know exactly what type of class it needs to be? you cannot generically do:
if(o instanceof <Class variable>.getClass()) {
as it gives a compile error.
Instead, here is an alternative - isAssignableFrom()
For example:
public static boolean isASubClass(Class classTypeWeWant, Object objectWeHave) {
return classTypeWeWant.isAssignableFrom(objectWeHave.getClass())
}
these days div is the new norm
<div style="float:left"><img.. ></div>

You may check *spell
en-GB dictionary used by Mozilla, OpenOffice, plenty of other software.
I feel like the simplest solution is sans javascript and simply putting the link in each cell (provided you don't have massive gullies between your cells or really think border lines). Have your css:
.tableClass td a{
display: block;
}
and then add a link per cell:
<table class="tableClass">
<tr>
<td><a href="#link">Link name</a></td>
<td><a href="#link">Link description</a></td>
<td><a href="#link">Link somthing else</a></td>
</tr>
</table>
boring but clean.
Just launch the VS Code
from the Anaconda Navigator
. It works for me.
If the file is local as your comment about SITE_PATH
suggest, it's pretty simple just execute the script and cache the result in a variable using the output control functions :
function print_xml_data_file()
{
include(XML_DATA_FILE_DIRECTORY . 'cms/data.php');
}
function get_xml_data()
{
ob_start();
print_xml_data_file();
$xml_file = ob_get_contents();
ob_end_clean();
return $xml_file;
}
If it's remote as lot of others said curl
is the way to go. If it isn't present try socket_create
or fsockopen
. If nothing work... change your hosting provider.
Use ByteArrayInputStream
:
InputStream is = new ByteArrayInputStream(decodedBytes);
default_scope
This works for Rails 4+:
class Book < ActiveRecord::Base
default_scope { order(created_at: :desc) }
end
For Rails 2.3, 3, you need this instead:
default_scope order('created_at DESC')
For Rails 2.x:
default_scope :order => 'created_at DESC'
Where created_at
is the field you want the default sorting to be done on.
Note: ASC is the code to use for Ascending and DESC is for descending (desc
, NOT dsc
!).
scope
Once you're used to that you can also use scope
:
class Book < ActiveRecord::Base
scope :confirmed, :conditions => { :confirmed => true }
scope :published, :conditions => { :published => true }
end
For Rails 2 you need named_scope
.
:published
scope gives you Book.published
instead of
Book.find(:published => true)
.
Since Rails 3 you can 'chain' those methods together by concatenating them with periods between them, so with the above scopes you can now use Book.published.confirmed
.
With this method, the query is not actually executed until actual results are needed (lazy evaluation), so 7 scopes could be chained together but only resulting in 1 actual database query, to avoid performance problems from executing 7 separate queries.
You can use a passed in parameter such as a date or a user_id (something that will change at run-time and so will need that 'lazy evaluation', with a lambda, like this:
scope :recent_books, lambda
{ |since_when| where("created_at >= ?", since_when) }
# Note the `where` is making use of AREL syntax added in Rails 3.
Finally you can disable default scope with:
Book.with_exclusive_scope { find(:all) }
or even better:
Book.unscoped.all
which will disable any filter (conditions) or sort (order by).
Note that the first version works in Rails2+ whereas the second (unscoped) is only for Rails3+
So
... if you're thinking, hmm, so these are just like methods then..., yup, that's exactly what these scopes are!
They are like having def self.method_name ...code... end
but as always with ruby they are nice little syntactical shortcuts (or 'sugar') to make things easier for you!
In fact they are Class level methods as they operate on the 1 set of 'all' records.
Their format is changing however, with rails 4 there are deprecation warning when using #scope without passing a callable object. For example scope :red, where(color: 'red') should be changed to scope :red, -> { where(color: 'red') }
.
As a side note, when used incorrectly, default_scope can be misused/abused.
This is mainly about when it gets used for actions like where
's limiting (filtering) the default selection (a bad idea for a default) rather than just being used for ordering results.
For where
selections, just use the regular named scopes. and add that scope on in the query, e.g. Book.all.published
where published
is a named scope.
In conclusion, scopes are really great and help you to push things up into the model for a 'fat model thin controller' DRYer approach.
To comment/uncomment one line, use: Ctrl + /.
To comment/uncomment a block, use: Ctrl + Shift + /.

Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.
Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).
"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.
str.splitlines
method should give you exactly that.
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
Try to call your library after include PREBUILT_SHARED_LIBRARY
section:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libcalculate
LOCAL_SRC_FILES := <PATH>/libcalculate.so
include $(PREBUILT_SHARED_LIBRARY)
#...
LOCAL_SHARED_LIBRARIES += libcalculate
Update:
If you will use this library in Java you need compile it as shared library
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libcalculate
LOCAL_SRC_FILES := <PATH>/libcalculate.so
include $(BUILD_SHARED_LIBRARY)
And you need deploy the library in the /vendor/lib
directory.
Whenever you see this error, go to Configuration directory and check for a log file generated just now. It should have proper Exception stacktrace. Mine was a case where I got an updated 32-bit JRE (or JVM) installed which was the default Java that got added to the Path. And my Eclipse installation was 64-bit which meant it needed a 64-bit VM to run its native SWT libraries. So I simply uninstalled the 32-bit JVM and replaced it with a 64-bit JVM.
I wonder if they will improve this reporting mechanism, instead of silently generating a log file in some directory.
Following worked for me:
<context:property-placeholder location="file:src/resources/spring/AppController.properties"/>
Somehow "classpath:xxx" is not picking the file.
For replace you can use vbCrLf
:
Replace(string, vbCrLf, "")
You can also use chr(13)+chr(10)
.
I seem to remember in some odd cases that chr(10)
comes before chr(13)
.
The following lines should be updated in app -> main -> res -> values -> Styles.xml
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>
<!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme -->
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
<item name="android:src">@drawable/ic_launcher</item>
<item name="android:background">?android:attr/actionBarItemBackground</item>
<item name="android:contentDescription">"Lala"</item>
</style>
This is how it can be done. If you want to change the overflow icon in action bar
You can do
df['column'] = None #This works. This will create a new column with None type
df.column = None #This will work only when the column is already present in the dataframe
You can also add hash when page is loading:
location.hash = "noBack";
Then just handle location hash change to add another hash:
$(window).on('hashchange', function() {
location.hash = "noBack";
});
That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.
You can get result distinct by two columns use below SQL:
SELECT COUNT(*) FROM (SELECT DISTINCT c1, c2 FROM [TableEntity]) TE
You can add this in yourProject/app/build.gradle
inside android{}
android {
packagingOptions {

exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/license.txt'

If you need this procedure for variable fieldnames instead of id
this might be helpful:
DROP PROCEDURE IF EXISTS update_auto_increment;
DELIMITER //
CREATE PROCEDURE update_auto_increment (_table VARCHAR(128), _fieldname VARCHAR(128))
BEGIN
DECLARE _max_stmt VARCHAR(1024);
DECLARE _stmt VARCHAR(1024);
SET @inc := 0;
SET @MAX_SQL := CONCAT('SELECT IFNULL(MAX(',_fieldname,'), 0) + 1 INTO @inc FROM ', _table);
PREPARE _max_stmt FROM @MAX_SQL;
EXECUTE _max_stmt;
DEALLOCATE PREPARE _max_stmt;
SET @SQL := CONCAT('ALTER TABLE ', _table, ' AUTO_INCREMENT = ', @inc);
PREPARE _stmt FROM @SQL;
EXECUTE _stmt;
DEALLOCATE PREPARE _stmt;
END //
DELIMITER ;
CALL update_auto_increment('your_table_name', 'autoincrement_fieldname');

For a new project select the home directory of the jdk
eg C:\Java\jdk1.7.0_99
or C:\Program Files\Java\jdk1.7.0_99
For an existing project.
1) You need to have a jdk
installed on the system.
for instance in
C:\Java\jdk1.7.0_99
2) go to project structure
under File
menu ctrl+alt+shift+S
3) SDKs
is located under Platform Settings
. Select it.
4) click the green +
up the top of the window.
5) select JDK
(I have to use keyboard to select it do not know why).
select the home directory for your jdk installation.
should be good to go.
No need for that much code.
You can do all this stuff without coding so much by using only viewpager
with tablayout
.
Your main Layout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
<android.support.design.widget.TabLayout
android:id="@+id/tabDots"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="@drawable/tab_selector"
app:tabGravity="center"
app:tabIndicatorHeight="0dp"/>
</RelativeLayout>
Hook up your UI elements inactivity or fragment as follows:
Java Code:
mImageViewPager = (ViewPager) findViewById(R.id.pager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabDots);
tabLayout.setupWithViewPager(mImageViewPager, true);
That's it, you are good to go.
You will need to create the following xml resource file in the drawable folder.
tab_indicator_selected.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="4dp"
android:useLevel="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/colorAccent"/>
</shape>
tab_indicator_default.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="oval"
android:thickness="2dp"
android:useLevel="false">
<solid android:color="@android:color/darker_gray"/>
</shape>
tab_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/tab_indicator_selected"
android:state_selected="true"/>
<item android:drawable="@drawable/tab_indicator_default"/>
</selector>
Feeling as lazy as I am? Well, all the above code is converted into a library!
Usage
Add the following in your gradle:
implementation 'com.chabbal:slidingdotsplash:1.0.2'
Add the following to your Activity or Fragment layout.
<com.chabbal.slidingdotsplash.SlidingSplashView
android:id="@+id/splash"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:imageResources="@array/img_id_arr"/>
Create an integer array in strings.xml
e.g.
<integer-array name="img_id_arr">
<item>@drawable/img1</item>
<item>@drawable/img2</item>
<item>@drawable/img3</item>
<item>@drawable/img4</item>
</integer-array>
Done!

To elaborate some more on this, adding
script-src 'self' http://somedomain 'unsafe-inline' 'unsafe-eval';
to the meta tag like so,
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; script-src 'self' https://somedomain.com/ 'unsafe-inline' 'unsafe-eval'; media-src *">
fixes the error.
You can use $(function(){ // code });
which is executed when the document is ready to execute the code inside that block.
$(function(){
$('#clicker').click(function(){
alert('hey');
$('.hide_div').hide();
});
});
Add the below property into the web.config file for IIS sites. This worked for me on my intranet in IE11.
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=edge" />
</customHeaders>
</httpProtocol>

Stop Using MySQLDb if you want to avoid installing mysql headers just to access mysql from python.
Use pymysql. It does all of what MySQLDb does, but it was implemented purely in Python with NO External Dependencies. This makes the installation process on all operating systems consistent and easy. pymysql
is a drop in replacement for MySQLDb and IMHO there is no reason to ever use MySQLDb for anything... EVER! - PTSD from installing MySQLDb on Mac OSX and *Nix systems
, but that's just me.
Installation
pip install pymysql
That's it... you are ready to play.
Example usage from pymysql Github repo
import pymysql.cursors
import pymysql
# Connect to the database
connection = pymysql.connect(host='localhost',
user='user',
password='passwd',
db='db',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
try:
with connection.cursor() as cursor:
# Create a new record
sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
cursor.execute(sql, ('[email protected]', 'very-secret'))
# connection is not autocommit by default. So you must commit to save
# your changes.
connection.commit()
with connection.cursor() as cursor:
# Read a single record
sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
cursor.execute(sql, ('[email protected]',))
result = cursor.fetchone()
print(result)
finally:
connection.close()
ALSO - Replace MySQLdb in existing code quickly and transparently
If you have existing code that uses MySQLdb, you can easily replace it with pymysql using this simple process:
# import MySQLdb << Remove this line and replace with:
import pymysql
pymysql.install_as_MySQLdb()
All subsequent references to MySQLdb will use pymysql transparently.
$location.path('/configuration/streaming');
this will work...
inject the location service in controller
You can read data direct from some file and plot
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
from matplotlib import cm
import numpy as np
from sys import argv
x,y,z = np.loadtxt('your_file', unpack=True)
fig = plt.figure()
ax = Axes3D(fig)
surf = ax.plot_trisurf(x, y, z, cmap=cm.jet, linewidth=0.1)
fig.colorbar(surf, shrink=0.5, aspect=5)
plt.savefig('teste.pdf')
plt.show()
If necessary you can pass vmin and vmax to define the colorbar range, e.g.
surf = ax.plot_trisurf(x, y, z, cmap=cm.jet, linewidth=0.1, vmin=0, vmax=2000)
I was wondering how to do some interactive plots, in this case with artificial data
from __future__ import print_function
from ipywidgets import interact, interactive, fixed, interact_manual
import ipywidgets as widgets
from IPython.display import Image
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits import mplot3d
def f(x, y):
return np.sin(np.sqrt(x ** 2 + y ** 2))
def plot(i):
fig = plt.figure()
ax = plt.axes(projection='3d')
theta = 2 * np.pi * np.random.random(1000)
r = i * np.random.random(1000)
x = np.ravel(r * np.sin(theta))
y = np.ravel(r * np.cos(theta))
z = f(x, y)
ax.plot_trisurf(x, y, z, cmap='viridis', edgecolor='none')
fig.tight_layout()
interactive_plot = interactive(plot, i=(2, 10))
interactive_plot
np.isnan combined with np.argwhere
x = np.array([[1,2,3,4],
[2,3,np.nan,5],
[np.nan,5,2,3]])
np.argwhere(np.isnan(x))
output:
array([[1, 2],
[2, 0]])
You need to create a set of escaped (with \
) parentheses (that match the parentheses) and a group of regular parentheses that create your capturing group:
var regExp = /\(([^)]+)\)/;_x000D_
var matches = regExp.exec("I expect five hundred dollars ($500).");_x000D_
_x000D_
//matches[1] contains the value between the parentheses_x000D_
console.log(matches[1]);
_x000D_
Breakdown:
\(
: match an opening parentheses(
: begin capturing group[^)]+
: match one or more non )
characters)
: end capturing group\)
: match closing parenthesesHere is a visual explanation on RegExplained
Android, Python !
When I saw these two keywords together in your question, Kivy is the one which came to my mind first.
Before coming to native Android development in Java using Android Studio, I had tried Kivy. It just awesome. Here are a few advantage I could find out.
Simple to use
With a python basics, you won't have trouble learning it.
Good community
It's well documented and has a great, active community.
Cross platform.
You can develop thing for Android, iOS, Windows, Linux and even Raspberry Pi with this single framework. Open source.
It is a free software
At least few of it's (Cross platform) competitors want you to pay a fee if you want a commercial license.
Accelerated graphics support
Kivy's graphics engine build over OpenGL ES 2 makes it suitable for softwares which require fast graphics rendering such as games.
Now coming into the next part of question, you can't use Android Studio IDE for Kivy. Here is a detailed guide for setting up the development environment.
There are a lot of really good solutions here. But I thought that I would go ahead and put mine in here as another alternative. It's just a simple jQuery snippet that does it the way bootstrap would if it supported hover for dropdowns instead of just click. I've only tested this with version 3 so I don't know if it would work with version 2. Save it as a snippet in your editor and have it at the stroke of a key.
<script>
$(function() {
$(".dropdown").hover(
function(){ $(this).addClass('open') },
function(){ $(this).removeClass('open') }
);
});
</script>
Basically, It's just saying when you hover on the dropdown class, it will add the open class to it. Then it just works. When you stop hovering on either the parent li with the dropdown class or the child ul/li's, it removes the open class. Obviously, this is only one of many solutions, and you can add to it to make it work on only specific instances of .dropdown. Or add a transition to either parent or child.
Simply inject it..
@Autowired
private ApplicationContext appContext;
or implement this interface: ApplicationContextAware
It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap
object and draw into that using the Graphics.CopyFromScreen
method.
Sample code:
using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
Screen.PrimaryScreen.Bounds.Y,
0, 0,
bmpScreenCapture.Size,
CopyPixelOperation.SourceCopy);
}
Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.
It 'a permission problem when IIS is running I had this problem and I solved it in this way
I went on folders
C:\Windows\ System32\config\SystemProfile
and
C:\Windows\SysWOW64\config\SystemProfile
are protected system folders, they usually have the lock.
Right-click-> Card security-> Click on Edit-> Add untente "Autenticadet User" and assign permissions.
At this point everything is solved, if you still have problems try to give all permissions to "Everyone"
From ES2016 you can also use slightly better / easier / more elegant method (case-sensitive):
if (referrer.includes("Ral")) { ... }
or (case-insensitive):
if (referrer.toLowerCase().includes(someString.toLowerCase())) { ... }
Here is some comparison of .indexOf()
and .includes()
:
https://dev.to/adroitcoder/includes-vs-indexof-in-javascript
I may be missing part of the question, but I believe you can simply do this:
$('.testimonial').each((index, element) => {
if (/* Condition */) {
// Do Something
}
});
This uses jQuery's each method: https://learn.jquery.com/using-jquery-core/iterating/

'transection_datetime' => '',
'created_by' => '1',
'status_id' => '1', )
);
dd(UserSubscription::insert($user_subscription_array));
UserSubscription
is my model name.
This will return "true" if insert successfully else "false".
I actually prefer to use the html button form element and make it runat=server. The button element can hold other elements inside it. You can even add formatting inside it with span's or strong's. Here is an example:
<button id="BtnSave" runat="server"><img src="Images/save.png" />Save</button>
After 48 hours of the still not being updated I removed the app from sale on Pricing and Availability.
Then I waited 1 hour.
Then I ticked All Territories Selected again.
After the app came available for download again the version number was updated.
Using jackson, you can do it as follows:
ObjectMapper mapper = new ObjectMapper();
String clientFilterJson = "";
try {
clientFilterJson = mapper.writeValueAsString(filterSaveModel);
} catch (IOException e) {
e.printStackTrace();
}
Just open a command shell and type (saying your port is 123456):
netstat -a -n -o | find "123456"
You will see everything you need.
The headers are:
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:37 0.0.0.0:0 LISTENING 1111
In my project I use following code:
$('#attribute').select2();
$('#attribute').bind('change', function(){
var $options = $();
for (var i in data) {
$options = $options.add(
$('<option>').attr('value', data[i].id).html(data[i].text)
);
}
$('#value').html($options).trigger('change');
});
Try to comment out the select2 part. The rest of the code will still work.
A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null
The second pipe was interpreted by this web site when submitted... You need two backslashes at the beginning. So make sure to use System.IO.Directory.GetFiles(@"\\.\pipe\").
Note that I have seen this function call throw an 'illegal characters in path.' exception when one of the pipes on my machine had invalid characters. PipleList.exe worked ok though, so it seems like a bug in MS's .net code.
Assuming that you want to reduce dependencies to other assemblies and to keep things simple, you can do:
var sb = new System.Text.StringBuilder();
sb.Append("a=" + HttpUtility.UrlEncode("TheValueOfA") + "&");
sb.Append("b=" + HttpUtility.UrlEncode("TheValueOfB") + "&");
sb.Append("c=" + HttpUtility.UrlEncode("TheValueOfC") + "&");
sb.Append("d=" + HttpUtility.UrlEncode("TheValueOfD") + "&");
sb.Remove(sb.Length-1, 1); // Remove the final '&'
string result = sb.ToString();
This works well with loops too. The final ampersand removal needs to go outside of the loop.
Note that the concatenation operator is used to improve readability. The cost of using it compared to the cost of using a StringBuilder is minimal (I think Jeff Atwood posted something on this topic).
You can also get strange messages about the need to upgrade your working copy when there are other working copies nested into yours. I had this issue with a Symphony project were some framework folders are working copy, that I suppose have not been cleaned up properly before they were published.
In this case, just make a file search for .svn
, and delete the .svn
folders that you don't want (don't delete yours at the root of course).
It is possible and Spring MVC 3 does it, but I didn't take the time to see exactly how.
The matching of method parameter names to URI Template variable names can only be done if your code is compiled with debugging enabled. If you do have not debugging enabled, you must specify the name of the URI Template variable name in the @PathVariable annotation in order to bind the resolved value of the variable name to a method parameter. For example:
Taken from the spring documentation
For a long time, CMake had the add_definitions
command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options).
An example using the new add_compile_definitions:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION})
add_compile_definitions(WITH_OPENCV2)
Or:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2)
The good part about this is that it circumvents the shabby trickery CMake has in place for add_definitions
. CMake is such a shabby system, but they are finally finding some sanity.
Find more explanation on which commands to use for compiler flags here: https://cmake.org/cmake/help/latest/command/add_definitions.html
Likewise, you can do this per-target as explained in Jim Hunziker's answer.
This is a right answer. you need to import FormsMoudle
first in app.module.ts
**
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
FormsModule,
ReactiveFormsModule ,
BrowserModule,
AppRoutingModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
** second in app.component.spec.ts
import { TestBed, async } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { AppComponent } from './app.component';
import { FormsModule } from '@angular/forms';

The best and easy way to get the activity context is putting .this
after the name of the Activity. For example: If your Activity's name is SecondActivity
, its context will be SecondActivity.this
You don't need jQuery for that, you can do it with normal javascript:
http://www.w3schools.com/jsref/jsref_split.asp
var str = "a,b,c,d";
var res = str.split(","); // this returns an array
First off, I know the addEventListener
method has been mentioned in the comments above, but I didn't see any code. Since it's the preferred approach, here it is:
window.addEventListener('resize', function(event){
// do stuff here
});
Here's another way to possibly answer your question using the find function which gives you a literal numerical value of where something truly is
open('file', 'r').read().find('')
in find write the word you want to find
and 'file'
stands for your file name
My problem was that I forgot that I added a proxy in gradle.properties
in C:\Users\(current user)\.gradle
like:
systemProp.http.proxyHost=****
systemProp.http.proxyPort=8850
FILE_NAME = 'file.txt'
wordCounter = {}
with open(FILE_NAME,'r') as fh:
for line in fh:
# Replacing punctuation characters. Making the string to lower.
# The split will spit the line into a list.
word_list = line.replace(',','').replace('\'','').replace('.','').lower().split()
for word in word_list:
# Adding the word into the wordCounter dictionary.
if word not in wordCounter:
wordCounter[word] = 1
else:
# if the word is already in the dictionary update its count.
wordCounter[word] = wordCounter[word] + 1
print('{:15}{:3}'.format('Word','Count'))
print('-' * 18)
# printing the words and its occurrence.
for (word,occurance) in wordCounter.items():
print('{:15}{:3}'.format(word,occurance))
#

Most of the existing answers explain the How, but very few explain the Why. And before you go around executing code from strangers on the Internet, especially code that disables security measures, you should understand exactly what you're doing. So here's a little more detail on this problem.
From the TechNet About Execution Policies Page:
Windows PowerShell execution policies let you determine the conditions under which Windows PowerShell loads configuration files and runs scripts.
The benefits of which, as enumerated by PowerShell Basics - Execution Policy and Code Signing, are:
- Control of Execution - Control the level of trust for executing scripts.
- Command Highjack - Prevent injection of commands in my path.
- Identity - Is the script created and signed by a developer I trust and/or a signed with a certificate from a Certificate Authority I trust.
- Integrity - Scripts cannot be modified by malware or malicious user.
To check your current execution policy, you can run Get-ExecutionPolicy
. But you're probably here because you want to change it.
To do so you'll run the Set-ExecutionPolicy
cmdlet.
You'll have two major decisions to make when updating the execution policy.
Restricted
† - No Script either local, remote or downloaded can be executed on the system.AllSigned
- All script that are ran require to be digitally signed.RemoteSigned
- All remote scripts (UNC) or downloaded need to be signed.Unrestricted
- No signature for any type of script is required.LocalMachine
† - The execution policy affects all users of the computer.CurrentUser
- The execution policy affects only the current user.Process
- The execution policy affects only the current Windows PowerShell process.† = Default
For example: if you wanted to change the policy to RemoteSigned for just the CurrentUser, you'd run the following command:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Note: In order to change the Execution policy, you must be running PowerShell As Adminstrator. If you are in regular mode and try to change the execution policy, you'll get the following error:
Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option.
If you want to tighten up the internal restrictions on your own scripts that have not been downloaded from the Internet (or at least don't contain the UNC metadata), you can force the policy to only run signed sripts. To sign your own scripts, you can follow the instructions on Scott Hanselman's article on Signing PowerShell Scripts.
Note: Most people are likely to get this error whenever they open Powershell because the first thing PS tries to do when it launches is execute your user profile script that sets up your environment however you like it.
The file is typically located in:
%UserProfile%\My Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1
You can find the exact location by running the powershell variable
$profile
If there's nothing that you care about in the profile, and don't want to fuss with your security settings, you can just delete it and powershell won't find anything that it cannot execute.
The collection results you get back from a jQuery collection do not support set-based comparison. You can use compare the individual members one by one though, there are no utilities for this that I know of in jQuery.
You can use the ParseExact() method to obtain a DateTime object. You can then use the ToString() method of that DateTime object to convert the string to what ever you need as shown here.

onStopTrackingTouch
.As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them.
That's right. Remember that you're writing the condition in terms of what you want to keep, not in terms of what you want to drop. For df1
:
df1 = df[(df.a != -1) & (df.b != -1)]
You're saying "keep the rows in which df.a
isn't -1 and df.b
isn't -1", which is the same as dropping every row in which at least one value is -1.
For df2
:
df2 = df[(df.a != -1) | (df.b != -1)]
You're saying "keep the rows in which either df.a
or df.b
is not -1", which is the same as dropping rows where both values are -1.
PS: chained access like df['a'][1] = -1
can get you into trouble. It's better to get into the habit of using .loc
and .iloc
.
If I remember correctly from my own use of bootstrap, the .spanN
classes are floated, which automatically makes them behave as display: block
. To make display: table-cell
work, you need to remove the float.
#since this was yesterday
date -dyesterday +%Y%m%d
#more precise, and more recommended
date -d'27 JUN 2011' +%Y%m%d
#assuming this is similar to yesterdays `date` question from you
#http://stackoverflow.com/q/6497525/638649
date -d'last-monday' +%Y%m%d
#going on @seth's comment you could do this
DATE="27 jun 2011"; date -d"$DATE" +%Y%m%d
#or a method to read it from stdin
read -p " Get date >> " DATE; printf " AS YYYYMMDD format >> %s" `date
-d"$DATE" +%Y%m%d`
#which then outputs the following:
#Get date >> 27 june 2011
#AS YYYYMMDD format >> 20110627
#if you really want to use awk
echo "27 june 2011" | awk '{print "date -d\""$1FS$2FS$3"\" +%Y%m%d"}' | bash
#note | bash just redirects awk's output to the shell to be executed
#FS is field separator, in this case you can use $0 to print the line
#But this is useful if you have more than one date on a line
note this only works on GNU date
I have read that:
Solaris version of date, which is unable to support

can be resolve with replacing sunfreeware.com version of date
I have actually done this using a bit of sleight of hand: a single lookup table with 16 entries will suffice and all you have to do is break the binary rep into nibbles (4-bit tuples). The complexity is in fact O(1) and I wrote a C++ template which was specialized on the size of the integer you wanted (in # bits)… makes it a constant expression instead of indetermined.
fwiw you can use the fact that (i & -i) will return you the LS one-bit and simply loop, stripping off the lsbit each time, until the integer is zero — but that’s an old parity trick.
You can use
change config to cookie & type your password in ' ' in password like bellow
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'your password';
Then save & type on browser localhost/phpmyadmin/
Enter your given password & enjoy
I had a requirement to register user. In that case I need to check whether that username is already present in the database or not. I have tried the below in C# windows form application(EntityFramework) and it worked.
var result = incomeExpenseManagementDB.Users.FirstOrDefault(x => x.userName == registerUserView.uNameText);
if (result == null) {
register.registerUser(registerUserView.fnameText, registerUserView.lnameText, registerUserView.eMailText, registerUserView.mobileText, registerUserView.bDateText, registerUserView.uNameText, registerUserView.pWordText);
} else {
MessageBox.Show("User Alreay Exist. Try with Different Username");
}
One other option is to use a plyr function:
df <- ldply(listOfDataFrames, data.frame)
This is a little slower than the original:
> system.time({ df <- do.call("rbind", listOfDataFrames) })
user system elapsed
0.25 0.00 0.25
> system.time({ df2 <- ldply(listOfDataFrames, data.frame) })
user system elapsed
0.30 0.00 0.29
> identical(df, df2)
[1] TRUE
My guess is that using do.call("rbind", ...)
is going to be the fastest approach that you will find unless you can do something like (a) use a matrices instead of a data.frames and (b) preallocate the final matrix and assign to it rather than growing it.
Edit 1:
Based on Hadley's comment, here's the latest version of rbind.fill
from CRAN:
> system.time({ df3 <- rbind.fill(listOfDataFrames) })
user system elapsed
0.24 0.00 0.23
> identical(df, df3)
[1] TRUE
This is easier than rbind, and marginally faster (these timings hold up over multiple runs). And as far as I understand it, the version of plyr
on github is even faster than this.
Your schema is for its target namespace http://www.example.org/Test
so it defines an element with name MyElement
in that target namespace http://www.example.org/Test
. Your instance document however has an element with name MyElement
in no namespace. That is why the validating parser tells you it can't find a declaration for that element, you haven't provided a schema for elements in no namespace.
You either need to change the schema to not use a target namespace at all or you need to change the instance to use e.g. <MyElement xmlns="http://www.example.org/Test">A</MyElement>
.
Following a solution for Kotlin programmers (from API 22)
val res = context?.let { ContextCompat.getDrawable(it, R.id.any_resource }
Use the AsyncTask class (instead of Runnable). It has a method called onProgressUpdate which can affect the UI (it's invoked in the UI thread).

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands
OP, you can convert a string to type Boolean
by using any of the methods stated below:
string sample = "True";
bool myBool = bool.Parse(sample);
///or
bool myBool = Convert.ToBoolean(sample);
bool.Parse
expects one parameter which in this case is sample
, .ToBoolean
also expects one parameter.
You can use TryParse
which is the same as Parse
but it doesn't throw any exception :)
string sample = "false";
Boolean myBool;
if (Boolean.TryParse(sample , out myBool))
{
}
Please note that you cannot convert any type of string to type Boolean
because the value of a Boolean
can only be True
or False
Hope you understand :)
I followed the following steps and it worked for me.
fetch heroku
reset --hard heroku/master
Then try to 'git push heroku'. An easier solution is to use the user:pass@host format directly in the URL.
Using the request library:
var request = require('request'),
username = "john",
password = "1234",
url = "http://" + username + ":" + password + "@www.example.com";
request(
{
url : url
},
function (error, response, body) {
// Do more stuff with 'body' here
}
);
I've written a little blogpost about this as well.
More simple way...:
Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
Dim dv As New DataView(dt)
If GridView1.Attributes("dir") = SortDirection.Ascending Then
dv.Sort = e.SortExpression & " DESC"
GridView1.Attributes("dir") = SortDirection.Descending
Else
GridView1.Attributes("dir") = SortDirection.Ascending
dv.Sort = e.SortExpression & " ASC"
End If
GridView1.DataSource = dv
GridView1.DataBind()
Didn't find any solution that would work with UTF-8 characters. String.fromCharCode
is good until you meet 2 byte character.
For example Hüser will come as [0x44,0x61,0x6e,0x69,0x65,0x6c,0x61,0x20,0x48,0xc3,0xbc,0x73,0x65,0x72]
But if you go through it with String.fromCharCode
you will have Hüser as each byte will be converted to a char separately.
Currently I'm using following solution:
function pad(n) { return (n.length < 2 ? '0' + n : n); }
function decodeUtf8(data) {
return decodeURIComponent(
data.map(byte => ('%' + pad(byte.toString(16)))).join('')
);
}
PHP by itself has no SMS module or functions and doesn't allow you to send SMS.
SMS ( Short Messaging System) is a GSM technology an you need a GSM provider that will provide this service for you and may have an PHP API implementation for it.
Usually people in telecom business use Asterisk to handle calls and sms programming.
It should work fine. Don't use tuple
, list
or other special names as a variable name. It's probably what's causing your problem.
>>> l = [4,5,6]
>>> tuple(l)
(4, 5, 6)
>>> tuple = 'whoops' # Don't do this
>>> tuple(l)
TypeError: 'tuple' object is not callable
select @currentTerm = CurrentTerm, @termID = TermID, @endDate = EndDate

According to the matplotlib legend documentation:
The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored).
Thus, one could use:
plt.legend(loc=(x, y))
to set the legend's lower left corner to the specified (x, y)
position.
Another possible cause of this error is a mismatched workgroup file. That is, if you try to use a secured (or partially-secured) MDB with a workgroup file other than the one used to secure it, you can trigger the error (I've seen it myself, years ago with Access 2000).

Beyond what's been said already about selectors, you may want to look at the NSInvocation class.
An NSInvocation is an Objective-C message rendered static, that is, it is an action turned into an object. NSInvocation objects are used to store and forward messages between objects and between applications, primarily by NSTimer objects and the distributed objects system.
An NSInvocation object contains all the elements of an Objective-C message: a target, a selector, arguments, and the return value. Each of these elements can be set directly, and the return value is set automatically when the NSInvocation object is dispatched.
Keep in mind that while it's useful in certain situations, you don't use NSInvocation in a normal day of coding. If you're just trying to get two objects to talk to each other, consider defining an informal or formal delegate protocol, or passing a selector and target object as has already been mentioned.
Here is how a UTF8 text file can be read from a zip archive into a string variable (.NET Framework 4.5 and up):
string zipFileFullPath = "{{TypeYourZipFileFullPathHere}}";
string targetFileName = "{{TypeYourTargetFileNameHere}}";
string text = new string(
(new System.IO.StreamReader(
System.IO.Compression.ZipFile.OpenRead(zipFileFullPath)
.Entries.Where(x => x.Name.Equals(targetFileName,
StringComparison.InvariantCulture))
.FirstOrDefault()
.Open(), Encoding.UTF8)
.ReadToEnd())
.ToArray());
You can raise a notice in Postgres

I have used Excel.dll library which is:
The documentation available over here: https://exceldatareader.codeplex.com/
Strongly recommendable.
In summary :
<input type="submit">
<button type="submit"> Submit </button>
Both by default will visually draw a button that performs the same action (submit the form).
However, it is recommended to use <button type="submit">
because it has better semantics, better ARIA support and it is easier to style.
Bash has select for this purpose.
select result in Yes No Cancel

After having a nightmare using the pip install -U numpy several months ago, I gave up. I went through installing CV2s and opencv without success.
I was using numpy ver 1.9.1 on python34 and the upgrade just kept stalling on on 1.9.
So I went to https://pypi.python.org/pypi/numpy and discovered the latest numpy version for my python3.4.
I downloaded the .whl file and copied it into the folder containing my python installation, C:\Python34, in my case.
I then ran pip intall on the file name and I can now import cv2 problem free.
Make sure you close down python before you start, obvious but essential

But I noticed you should duplicate content at spacer element. Thought it's not so bad, but I'd like also to apply title
popup for clipped text. And it means long text will appear third time in my code.
Here I propose to access title
attribute from :after
pseudo-element to generate spacer and keep HTML clean.
Works on IE8+, FF, Chrome, Safari, Opera

Based nodejs document, http://nodejs.org/api/stream.html#stream_event_finish,
it should handle writableStream's finish
event.
var writable = getWriteable();
var readable = getReadable();
readable.pipe(writable);
writable.on('finish', function(){ ... });
If the variable table
contains invalid characters (like a space) you should add square brackets around the variable.
public DataTable fillDataTable(string table)
{
string query = "SELECT * FROM dstut.dbo.[" + table + "]";
using(SqlConnection sqlConn = new SqlConnection(conSTR))
using(SqlCommand cmd = new SqlCommand(query, sqlConn))
{
sqlConn.Open();
DataTable dt = new DataTable();
dt.Load(cmd.ExecuteReader());
return dt;
}
}
By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input
There are some webkit css properties that should work on Chrome/Safari at least:

That's a 2px wide black text outline.
Load an image with characters as texture and draw the part of that texture depending on what character you want. You can create that texture using a paint program, hardcode it or use a window component to draw to an image and retrieve that image for an exact copy of system fonts.
No need to use Glut or any other extension, just basic OpenGL operability. It gets the job done, not to mention that its been done like this for decades by professional programmers in very succesfull games and other applications.
When you return value from server to jQuery's Ajax call you can also use the below code to indicate a server error:
return StatusCode(500, "My error");
Or
return StatusCode((int)HttpStatusCode.InternalServerError, "My error");
Or
Response.StatusCode = (int)HttpStatusCode.InternalServerError;
return Json(new { responseText = "my error" });
Codes other than Http Success codes (e.g. 200[OK]) will trigger the function in front of error:
in client side (ajax).
you can have ajax call like:
$.ajax({
type: "POST",
url: "/General/ContactRequestPartial",
data: {
HashId: id
},
success: function (response) {
console.log("Custom message : " + response.responseText);
}, //Is Called when Status Code is 200[OK] or other Http success code
error: function (jqXHR, textStatus, errorThrown) {
console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
}, //Is Called when Status Code is 500[InternalServerError] or other Http Error code
})
Additionally you can handle different HTTP errors from jQuery side like:
$.ajax({
type: "POST",
url: "/General/ContactRequestPartial",
data: {
HashId: id
},
statusCode: {
500: function (jqXHR, textStatus, errorThrown) {
console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
501: function (jqXHR, textStatus, errorThrown) {
console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
}
})
statusCode:
is useful when you want to call different functions for different status codes that you return from server.
You can see list of different Http Status codes here:Wikipedia

Why setContentView() in Android Had Been So Popular Till Now?
setContentView(int layoutid) - method of activity class. It shows layout on screen.
R.layout.main - is an integer number implemented in nested layout class of R.java class file.
At the run time device will pick up their layout based on the id given in setcontentview() method.
In Kotlin I have used Bellow like..
xml:
<EditText
android:id="@+id/et_amount"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:imeOptions="actionNext"
android:inputType="number"
android:singleLine="true" />
in kotlin:
et_amount.setOnEditorActionListener { v, actionId, event ->
if (actionId == EditorInfo.IME_ACTION_NEXT) {
// do some code
true
} else {
false
}
}
It works for me when I define the complete border
property. (JSFiddle here)
.field_set{
border: 1px #F00 solid;
}?
the reason is the border-style
that is set to none
by default for fieldsets. You need to override that as well.
Have you tried binding the list to the datagridview directly? If not, try that first because it will save you lots of pain. If you have tried it already, please tell us what went wrong so we can better advise you. Data binding gives you different behaviour depending on what interfaces your data object implements. For example, if your data object only implements IEnumerable
(e.g. List
), you will get very basic one-way binding, but if it implements IBindingList
as well (e.g. BindingList
, DataView
), then you get two-way binding.
You can reference those remote tracking branches ~(listed with git branch -r
) with the name of their remote.
You need to fetch the remote branch:
git fetch origin aRemoteBranch
If you want to merge one of those remote branches on your local branch:
git checkout master
git merge origin/aRemoteBranch
Note 1: For a large repo with a long history, you will want to add the --depth=1
option when you use git fetch
.
Note 2: These commands also work with other remote repos so you can setup an origin
and an upstream
if you are working on a fork.
Note 3: user3265569 suggests the following alias in the comments:
From
aLocalBranch
, rungit combine remoteBranch
Alias:combine = !git fetch origin ${1} && git merge origin/${1}
Opposite scenario: If you want to merge one of your local branch on a remote branch (as opposed to a remote branch to a local one, as shown above), you need to create a new local branch on top of said remote branch first:
git checkout -b myBranch origin/aBranch
git merge anotherLocalBranch
The idea here, is to merge "one of your local branch" (here anotherLocalBranch
) to a remote branch (origin/aBranch
).
For that, you create first "myBranch
" as representing that remote branch: that is the git checkout -b myBranch origin/aBranch
part.
And then you can merge anotherLocalBranch
to it (to myBranch
).
If you'd start Tomcat manually (not as service), then the CATALINA_OPTS environment variable is the way to go. If you'd start it as a service, then the settings are probably stored somewhere in the registry. I have Tomcat 6 installed in my machine and I found the settings at the HKLM\SOFTWARE\Apache Software Foundation\Procrun 2.0\Tomcat6\Parameters\Java
key.
Use the bash built-in variable SECONDS
. Each time you reference the variable it will return the elapsed time since the script invocation.
Example:
echo "Start $SECONDS"
sleep 10
echo "Middle $SECONDS"
sleep 10
echo "End $SECONDS"
Output:
Start 0
Middle 10
End 20
In node, the Mongo driver will give you an ISO string, not the object. (ex: Mon Nov 24 2014 01:30:34 GMT-0800 (PST)

As in the opencv-doc you can get video feed from a camera which is connected to your computer by following code.
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Display the resulting frame
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
You can change cap = cv2.VideoCapture(0)
index from 0
to 1
to access the 2nd camera.
Tested in opencv-3.2.0

This has happened to me. My issue was caused when I didn't mount Docker file system correctly, so I configured the Disk Image Location and re-bind File sharing mount, and this now worked correctly. For reference, I use Docker Desktop in Windows.
I usually go with:
Firstname: 30 chars
Lastname: 30 chars
Email: 50 chars
Address: 200 chars
If I am concerned about long fields for the names, I might sometimes go with 50 for the name fields too, since storage space is rarely an issue these days.
Hmm, I think I misunderstand the question but I'm going to risk it. What's wrong with the following straightforward method?
public static void CopyFilesRecursively(DirectoryInfo source, DirectoryInfo target) {
foreach (DirectoryInfo dir in source.GetDirectories())
CopyFilesRecursively(dir, target.CreateSubdirectory(dir.Name));
foreach (FileInfo file in source.GetFiles())
file.CopyTo(Path.Combine(target.FullName, file.Name));
}
EDIT Since this posting has garnered an impressive number of downvotes for such a simple answer to an equally simple question, let me add an explanation. Please read this before downvoting.
First of all, this code is not intendend as a drop-in replacement to the code in the question. It is for illustration purpose only.
Microsoft.VisualBasic.Devices.Computer.FileSystem.CopyDirectory
does some additional correctness tests (e.g. whether the source and target are valid directories, whether the source is a parent of the target etc.) that are missing from this answer. That code is probably also more optimized.
That said, the code works well. It has (almost identically) been used in a mature software for years. Apart from the inherent fickleness present with all IO handlings (e.g. what happens if the user manually unplugs the USB drive while your code is writing to it?), there are no known problems.
In particular, I’d like to point out that the use of recursion here is absolutely not a problem. Neither in theory (conceptually, it’s the most elegant solution) nor in practice: this code will not overflow the stack. The stack is large enough to handle even deeply nested file hierarchies. Long before stack space becomes a problem, the folder path length limitation kicks in.
Notice that a malicious user might be able to break this assumption by using deeply-nested directories of one letter each. I haven’t tried this. But just to illustrate the point: in order to make this code overflow on a typical computer, the directories would have to be nested a few thousand times. This is simply not a realistic scenario.
You need to correctly separate static data from instance data. In your code, onLoan
and setLoanItem()
are instance members. If you want to reference/call them you must do so via an instance. So you either want
public void loanItem() {
this.media.setLoanItem("Yes");
}
or
public void loanItem(Media object) {
object.setLoanItem("Yes");
}
depending on how you want to pass that instance around.
Forget switch
and break
, lets play with if
. And instead of asserting
if(pageid === "listing-page" || pageid === "home-page")
lets create several arrays with cases and check it with Array.prototype.includes()
var caseA = ["listing-page", "home-page"];
var caseB = ["details-page", "case04", "case05"];
if(caseA.includes(pageid)) {
alert("hello");
}
else if (caseB.includes(pageid)) {
alert("goodbye");
}
else {
alert("there is no else case");
}
The reason why things aren't stopping for you is because the process (doInBackground()) runs until it is finished. Therefore you should check if the thread is cancelled or not before doing stuff:
if(!isCancelled()){
// Do your stuff
}
So basically, if the thread is not cancelled, do it, otherwise skip it :) Could be useful to check for this some times during your operation, especially before time taking stuff.
Also it could be useful to "clean up" alittle in
onCancelled();

Here you can see the nature of Scanner:
double nextDouble()
Returns the next token as a double. If the next token is not a float or is out of range, InputMismatchException is thrown.

System.out.print(e.getMessage()); //try to find out specific reason.
}
UPDATE
CASE 1
I tried your code and there is nothing wrong with it. Your are getting that error because you must have entered String
value. When I entered a numeric value, it runs without any errors. But once I entered String
it throw
the same Exception
which you have mentioned in your question.
CASE 2
You have entered something, which is out of range as I have mentioned above.
I'm really wondering what you could have tried to enter. In my system, it is running perfectly without changing a single line of code. Just copy as it is and try to compile and run it.

public class Test {
public static void main(String... args) {
new Test().askForMarks(5);
}

Scanner reader = new Scanner(System.in);
while (index < student) {
System.out.print("Please enter a mark (0..30): ");
marks[index] = (double) checkValueWithin(0, 30);
index++;
}
}
public double checkValueWithin(int min, int max) {
double num;
Scanner reader = new Scanner(System.in);
num = reader.nextDouble();
while (num < min || num > max) {
System.out.print("Invalid. Re-enter number: ");
num = reader.nextDouble();
}
return num;
}
}
As you said, you have tried to enter 1.0
, 2.8
and etc. Please try with this code.
Note : Please enter number one by one, on separate lines. I mean, enter 2.7
, press enter and then enter second number (e.g. 6.7
).

I think it's a good idea to keep avoiding modules unless you stick them into separate namespaces. Because in Intellisense methods in modules will be visible from everywhere in that namespace.
So instead of ModuleName.MyMethod()
you end up with MyMethod()
popups in anywhere and this kind of invalidates the encapsulation. (at least in the programming level).
That's why I always try to create Class with shared methods, seems so much better.

Leave out the "if"
An object and an instance are the same thing.
Personally I prefer to use the word "instance" when referring to a specific object of a specific type, for example "an instance of type Foo". But when talking about objects in general I would say "objects" rather than "instances".
A reference either refers to a specific object or else it can be a null reference.
They say that they have to create an instance to their application. What does it mean?
They probably mean you have to write something like this:
Foo foo = new Foo();
If you are unsure what type you should instantiate you should contact the developers of the application and ask for a more complete example.
Set a transparent border and then change it:

You can set the border properties on the CALayer by accessing the layer property of the button.
First, add Quartz
#import <QuartzCore/QuartzCore.h>
Set properties:
myButton.layer.borderWidth = 2.0f;
myButton.layer.borderColor = [UIColor greenColor].CGColor;
See:
https://developer.apple.com/documentation/quartzcore/calayer#//apple_ref/occ/cl/CALayer
The CALayer in the link above allows you to set other properties like corner radius, maskToBounds etc...

You could also use this:
ini_alter('date.timezone','Asia/Calcutta');
You should call this before calling any date function. It accepts the key as the first parameter to alter PHP settings during runtime and the second parameter is the value.
I had done these things before I figured out this:
date_default_timezone_set("Asia/Calcutta");
- did not workini_alter()
- IT WORKEDdate_default_timezone_set("Asia/Calcutta");
- IT WORKEDFor me the init_alter()
method got it all working.

We have been creating a SaaS for users and providing them a script to attach in their website page, and it was not possible to attach a version with the script as user will attach the script to their website for functionalities and i can't force them to change the version each time we update the script

Explanation:
The user have attached the script provided to them in their website and we checked for the unique token attached with the script exists or not using jQuery selector and if not then load it dynamically with newer token (or version)
This is call the same script twice which could be a performance issue, but it really solves the problem of forcing the script to not load from the cache without putting the version in the actual script link given to the user or client
Disclaimer: Do not use if performance is a big issue in your case.
For iOS 9.0 and above use this code in app delegate
[[UIView appearanceWhenContainedInInstancesOfClasses:@[[UIAlertController class]]] setTintColor:[UIColor redColor]];
Is the standard procedure not working?
git stash save
git branch xxx HEAD
git checkout xxx
git stash pop
Shorter:
git stash
git checkout -b xxx
git stash pop
Although this shouldn't be a real solution, it does work locally if you are stuck
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).
One way around this is to bind your event handler in javascript (where it should be):
document.getElementById('optionID').onchange = function () {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:
window.changeMessage() {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
?
I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application
Excerpt from the linked page:
Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:
Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.
Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the
Include
method.Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace
Collection(x => x.Courses)
withReference(x => x.Administrator)
.) Typically you'd use explicit loading only when you've turned lazy loading off.Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.
There's only one registered mediatype for SVG, and that's the one you listed, image/svg+xml
. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I've seen cases where SVG used in CSS backgrounds fail to display unless served with the image/svg+xml
mediatype.
not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
The native lib is expected in one of the following locations
/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib
and not in
tomcat/lib
The files in tomcat/lib
are all jar
file and are added by tomcat to the classpath
so that they are available to your application.
The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar
, for linux it could be a .so
file, for windows it could be a .dll
file.
Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.
Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.
org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms
EDIT
The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.
If you are troubling with running your servlet then after the run on sever
command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.
It should be something like that
http://localhost:8080/<your-context-name>/<your-servlet-name>
EDIT 2
Try to call your servlet using the following url
http://localhost:8080/com.filecounter/FileCounter
Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF
.
It is better to configure your servlets there using servlet-name
servlet-class
and url-mapping
. It could look like that:
<servlet>
<description></description>
<display-name>File counter - My first servlet</display-name>
<servlet-name>file_counter</servlet-name>
<servlet-class>com.filecounter.FileCounter</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>file_counter</servlet-name>
<url-pattern>/FileFounter</url-pattern>
</servlet-mapping>
In eclipse dynamic web project the default context name is the same as your project name.
http://localhost:8080/<your-context-name>/FileCounter
will work too.

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.
If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:
SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;
This way, if the data in the fields changes, you don't have to update your combined field.
You are more vulnerable to attacks if using eval
: JSON is a subset of Javascript and json.parse just parses JSON whereas eval
would leave the door open to all JS expressions.
If the page elements and their background images are already in the DOM (i.e. you are not creating/changing them dynamically), then their background images will already be loaded. At that point, you may want to look at compression methods :)
I have the same requirement. I just want to print a result object into JSON format so I use the code below. I hope you find something in it.
// Code of Conversion
$query = "SELECT * FROM products;";
$result = mysqli_query($conn , $query);
if ($result) {
echo "</br>"."Results Found";
// Conversion of result object into JSON format
$rows = array();
while($temp = mysqli_fetch_assoc($result)) {
$rows[] = $temp;
}
echo "</br>" . json_encode($rows);
} else {
echo "No Results Found";
}
A simple way of doing this is via nargin
(N arguments in). The downside is you have to make sure that your argument list and the nargin checks match.
It is worth remembering that all inputs are optional, but the functions will exit with an error if it calls a variable which is not set. The following example sets defaults for b
and c
. Will exit if a
is not present.
function [ output_args ] = input_example( a, b, c )
if nargin < 1
error('input_example : a is a required input')
end
if nargin < 2
b = 20
end
if nargin < 3
c = 30
end
end
Additionally to Eugene Retunsky's answer, quoting from $http documentation regarding the response:
The response object has these properties:
data –
{string|Object}
– The response body transformed with the transform functions.status –
{number}
– HTTP status code of the response.headers –
{function([headerName])}
– Header getter function.config –
{Object}
– The configuration object that was used to generate the request.statusText –
{string}
– HTTP status text of the response.
Please note that the argument callback order for $resource (v1.6) is not the same as above:
Success callback is called with
(value (Object|Array), responseHeaders (Function), status (number), statusText (string))
arguments, where the value is the populated resource instance or collection object. The error callback is called with(httpResponse)
argument.
You could use closure compiler to generate a small, cross-browser flash detection:
// ==ClosureCompiler==
// @compilation_level ADVANCED_OPTIMIZATIONS
// @output_file_name default.js
// @formatting pretty_print
// @use_closure_library true
// ==/ClosureCompiler==
// ADD YOUR CODE HERE
goog.require('goog.userAgent.flash');
if (goog.userAgent.flash.HAS_FLASH) {
alert('flash version: '+goog.userAgent.flash.VERSION);
}else{
alert('no flash found');
}
which results in the following "compiled" code:
var a = !1,
b = "";
function c(d) {
d = d.match(/[\d]+/g);
d.length = 3;
return d.join(".")
}
if (navigator.plugins && navigator.plugins.length) {
var e = navigator.plugins["Shockwave Flash"];
e && (a = !0, e.description && (b = c(e.description)));
navigator.plugins["Shockwave Flash 2.0"] && (a = !0, b = "2.0.0.11")
} else {
if (navigator.mimeTypes && navigator.mimeTypes.length) {
var f = navigator.mimeTypes["application/x-shockwave-flash"];
(a = f && f.enabledPlugin) && (b = c(f.enabledPlugin.description))
} else {
try {
var g = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.7"),
a = !0,
b = c(g.GetVariable("$version"))
} catch (h) {
try {
g = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.6"), a = !0, b = "6.0.21"
} catch (i) {
try {
g = new ActiveXObject("ShockwaveFlash.ShockwaveFlash"), a = !0, b = c(g.GetVariable("$version"))
} catch (j) {}
}
}
}
}
var k = b;
a ? alert("flash version: " + k) : alert("no flash found");
The Newest MySQL Versions have the new BIT
data type in which you can specify the number of bits in the field, for example BIT(1)
to use as Boolean
type, because it can be only 0
or 1
.
Use subDays()
method:
$users = Users::where('status_id', 'active')
->where( 'created_at', '>', Carbon::now()->subDays(30))
->get();

If anyone ever needs this, if you need to convert an XMLGregorianCalendar
timezone to your current timezone from UTC, then all you need to do is set the timezone to 0
, then call toGregorianCalendar()
- it will stay the same timezone, but the Date
knows how to convert it to yours, so you can get the data from there.
XMLGregorianCalendar xmlStartTime = DatatypeFactory.newInstance()
.newXMLGregorianCalendar(
((GregorianCalendar)GregorianCalendar.getInstance());
xmlStartTime.setTimezone(0);
GregorianCalendar startCalendar = xmlStartTime.toGregorianCalendar();
Date startDate = startCalendar.getTime();
XMLGregorianCalendar xmlStartTime = DatatypeFactory.newInstance()
.newXMLGregorianCalendar(startCalendar);
xmlStartTime.setHour(startDate.getHours());
xmlStartTime.setDay(startDate.getDate());
xmlStartTime.setMinute(startDate.getMinutes());
xmlStartTime.setMonth(startDate.getMonth()+1);
xmlStartTime.setTimezone(-startDate.getTimezoneOffset());
xmlStartTime.setSecond(startDate.getSeconds());
xmlStartTime.setYear(startDate.getYear() + 1900);
System.out.println(xmlStartTime.toString());

To sort a 1D vector or a single column of data, just call the sort function and pass in your sequence.
On the other hand, the order function is necessary to sort data two-dimensional data--i.e., multiple columns of data collected in a matrix or dataframe.

Here is an excerpt of data for field goal attempts in the 2008 NFL season, a dataframe i've called 'fg'. suppose that these 10 data points represent all of the field goals attempted in 2008; further suppose you want to know the the distance of the longest field goal attempted that year, who kicked it, and whether it was good or not; you also want to know the second-longest, as well as the third-longest, etc.; and finally you want the shortest field goal attempt.
Well, you could just do this:
sort(fg$Dist, decreasing=T)
which returns: 50 48 43 37 34 32 26 25 25 20
That is correct, but not very useful--it does tell us the distance of the longest field goal attempt, the second-longest,...as well as the shortest; however, but that's all we know--eg, we don't know who the kicker was, whether the attempt was successful, etc. Of course, we need the entire dataframe sorted on the "Dist" column (put another way, we want to sort all of the data rows on the single attribute Dist. that would look like this:
Stadium Home Week Qtr Away Off Def Result Kicker Dist

This is what order does. It is 'sort' for two-dimensional data; put another way, it returns a 1D integer index comprised of the row numbers such that sorting the rows according to that vector, would give you a correct row-oriented sort on the column, Dist
Here's how it works. Above, sort was used to sort the Dist column; to sort the entire dataframe on the Dist column, we use 'order' exactly the same way as 'sort' is used above:
ndx = order(fg$Dist, decreasing=T)
(i usually bind the array returned from 'order' to the variable 'ndx', which stands for 'index', because i am going to use it as an index array to sort.)
that was step 1, here's step 2:
'ndx', what is returned by 'sort' is then used as an index array to re-order the dataframe, 'fg':
fg_sorted = fg[ndx,]
fg_sorted is the re-ordered dataframe immediately above.
In sum, 'sort' is used to create an index array (which specifies the sort order of the column you want sorted), which then is used as an index array to re-order the dataframe (or matrix).
Probably you want something like:
firstline = True
for row in kidfile:
if firstline: #skip first line
firstline = False
continue
# parse the line
An other way to achive the same result is calling readline
before the loop:
kidfile.readline() # skip the first line
for row in kidfile:
#parse the line
I was able to successfully pass through the data attribute in the ajax method. Here is my code
$.ajax({
url: "/api/Gigs/Cancel",
type: "DELETE",
data: {
"GigId": link.attr('data-gig-id')
}
})
The link.attr method simply returned the value of 'data-gig-id' .
Isolation level defines how the changes made to some data repository by one transaction affect other simultaneous concurrent transactions, and also how and when that changed data becomes available to other transactions. When we define a transaction using the Spring framework we are also able to configure in which isolation level that same transaction will be executed.
@Transactional(isolation=Isolation.READ_COMMITTED)
public void someTransactionalMethod(Object obj) {
}
READ_UNCOMMITTED isolation level states that a transaction may read data that is still uncommitted by other transactions.
READ_COMMITTED isolation level states that a transaction can't read data that is not yet committed by other transactions.
REPEATABLE_READ isolation level states that if a transaction reads one record from the database multiple times the result of all those reading operations must always be the same.
SERIALIZABLE isolation level is the most restrictive of all isolation levels. Transactions are executed with locking at all levels (read, range and write locking) so they appear as if they were executed in a serialized way.
Propagation is the ability to decide how the business methods should be encapsulated in both logical or physical transactions.
Spring REQUIRED behavior means that the same transaction will be used if there is an already opened transaction in the current bean method execution context.
REQUIRES_NEW behavior means that a new physical transaction will always be created by the container.
The NESTED behavior makes nested Spring transactions to use the same physical transaction but sets savepoints between nested invocations so inner transactions may also rollback independently of outer transactions.
The MANDATORY behavior states that an existing opened transaction must already exist. If not an exception will be thrown by the container.
The NEVER behavior states that an existing opened transaction must not already exist. If a transaction exists an exception will be thrown by the container.
The NOT_SUPPORTED behavior will execute outside of the scope of any transaction. If an opened transaction already exists it will be paused.
The SUPPORTS behavior will execute in the scope of a transaction if an opened transaction already exists. If there isn't an already opened transaction the method will execute anyway but in a non-transactional way.
You were right in thinking mod was a good place to start. Here is an expression which will return true if $number
is even, false if odd:
$number % 2 == 0
Works for every integerPHP value, see as well Arithmetic OperatorsPHP.
Example:
$number = 20;
if ($number % 2 == 0) {
print "It's even";
}
Output:
It's even
There are a couple of tactics I've used in the past to simulate networking issues;
