I've rolled singleton into a class, so other classes can inherit singleton properties.
Singleton.h :
static id sharedInstance = nil;
#define DEFINE_SHARED_INSTANCE + (id) sharedInstance { return [self sharedInstance:&sharedInstance]; } \
+ (id) allocWithZone:(NSZone *)zone { return [self allocWithZone:zone forInstance:&sharedInstance]; }
@interface Singleton : NSObject {
}
+ (id) sharedInstance;
+ (id) sharedInstance:(id*)inst;
+ (id) allocWithZone:(NSZone *)zone forInstance:(id*)inst;
@end
Singleton.m :
#import "Singleton.h"
@implementation Singleton
+ (id) sharedInstance {
return [self sharedInstance:&sharedInstance];
}
+ (id) sharedInstance:(id*)inst {
@synchronized(self)
{
if (*inst == nil)
*inst = [[self alloc] init];
}
return *inst;
}
+ (id) allocWithZone:(NSZone *)zone forInstance:(id*)inst {
@synchronized(self) {
if (*inst == nil) {
*inst = [super allocWithZone:zone];
return *inst; // assignment and return on first allocation
}
}
return nil; // on subsequent allocation attempts return nil
}
- (id)copyWithZone:(NSZone *)zone {
return self;
}
- (id)retain {
return self;
}
- (unsigned)retainCount {
return UINT_MAX; // denotes an object that cannot be released
}
- (void)release {
//do nothing
}
- (id)autorelease {
return self;
}
@end
And here is an example of some class, that you want to become singleton.
#import "Singleton.h"
@interface SomeClass : Singleton {
}
@end
@implementation SomeClass
DEFINE_SHARED_INSTANCE;
@end
The only limitation about Singleton class, is that it is NSObject subclass. But most time I use singletons in my code they are in fact NSObject subclasses, so this class really ease my life and make code cleaner.
It’s just <b>
instead of <bold>
:
Some <b>text</b> that I want bolded.
Note that <b>
just changes the appearance of the text. If you want to render it bold because you want to express a strong emphasis, you should better use the <strong>
element.
git diff --name-only --diff-filter=U | xargs git checkout --theirs
Seems to do the job. Note that you have to be cd'ed to the root directory of the git repo to achieve this.
You need to use Integer.parseInt(String)
private void jTextField2MouseClicked(java.awt.event.MouseEvent evt) {
if(evt.getSource()==jTextField2){
int jml = Integer.parseInt(jTextField3.getText());
jTextField1.setText(numberToWord(jml));
}
}
Some versions of the .NET framework do not support Enum.GetValues
. Here's a good workaround from Ideas 2.0: Enum.GetValues in Compact Framework:
public Enum[] GetValues(Enum enumeration)
{
FieldInfo[] fields = enumeration.GetType().GetFields(BindingFlags.Static | BindingFlags.Public);
Enum[] enumerations = new Enum[fields.Length];
for (var i = 0; i < fields.Length; i++)
enumerations[i] = (Enum) fields[i].GetValue(enumeration);
return enumerations;
}
As with any code that involves reflection, you should take steps to ensure it runs only once and results are cached.
Assuming you can only have one 'something1'
or 'something2'
, etc. per line, you can use a lookup table:
$lookupTable = @{
'something1' = 'something1aa'
'something2' = 'something2bb'
'something3' = 'something3cc'
'something4' = 'something4dd'
'something5' = 'something5dsf'
'something6' = 'something6dfsfds'
}
$original_file = 'path\filename.abc'
$destination_file = 'path\filename.abc.new'
Get-Content -Path $original_file | ForEach-Object {
$line = $_
$lookupTable.GetEnumerator() | ForEach-Object {
if ($line -match $_.Key)
{
$line -replace $_.Key, $_.Value
break
}
}
} | Set-Content -Path $destination_file
If you can have more than one of those, just remove the break
in the if
statement.
Windows 10 x64 released August 2015 - same issue arising. MSVCR110.dll is also found in the sysWOW64 folder (which is where I found it, copying to system32 does not help). To resolve:
Hopefully like me you have a MySQL database backup handy!
Variation of Aaron's answer. Using sed without temporary files
#!/bin/bash
VERSION=1.0.0
IMAGE=company/image
ID=$(docker build -t ${IMAGE} . | tail -1 | sed 's/.*Successfully built \(.*\)$/\1/')
docker tag ${ID} ${IMAGE}:${VERSION}
docker tag -f ${ID} ${IMAGE}:latest
If you're using pure JS you can simply do it like:
var input = document.getElementById('myInput');
if(input.value.length == 0)
input.value = "Empty";
Here's a demo: http://jsfiddle.net/nYtm8/
If this didn't work:
<ImageView
android:layout_gravity="center_horizontal"
android:paddingTop="10px"
android:paddingBottom="5px"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:src="@android:drawable/divider_horizontal_bright" />
Try this raw View:
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#000000" />
From New-style and classic classes:
Up to Python 2.1, old-style classes were the only flavour available to the user.
The concept of (old-style) class is unrelated to the concept of type: if
x
is an instance of an old-style class, thenx.__class__
designates the class ofx
, buttype(x)
is always<type 'instance'>
.This reflects the fact that all old-style instances, independently of their class, are implemented with a single built-in type, called instance.
New-style classes were introduced in Python 2.2 to unify the concepts of class and type. A new-style class is simply a user-defined type, no more, no less.
If x is an instance of a new-style class, then
type(x)
is typically the same asx.__class__
(although this is not guaranteed – a new-style class instance is permitted to override the value returned forx.__class__
).The major motivation for introducing new-style classes is to provide a unified object model with a full meta-model.
It also has a number of immediate benefits, like the ability to subclass most built-in types, or the introduction of "descriptors", which enable computed properties.
For compatibility reasons, classes are still old-style by default.
New-style classes are created by specifying another new-style class (i.e. a type) as a parent class, or the "top-level type" object if no other parent is needed.
The behaviour of new-style classes differs from that of old-style classes in a number of important details in addition to what type returns.
Some of these changes are fundamental to the new object model, like the way special methods are invoked. Others are "fixes" that could not be implemented before for compatibility concerns, like the method resolution order in case of multiple inheritance.
Python 3 only has new-style classes.
No matter if you subclass from
object
or not, classes are new-style in Python 3.
There's several different ways of doing this, with varying efficiency, depending on how good your query optimiser is, and the relative size of your two tables:
This is the shortest statement, and may be quickest if your phone book is very short:
SELECT *
FROM Call
WHERE phone_number NOT IN (SELECT phone_number FROM Phone_book)
alternatively (thanks to Alterlife)
SELECT *
FROM Call
WHERE NOT EXISTS
(SELECT *
FROM Phone_book
WHERE Phone_book.phone_number = Call.phone_number)
or (thanks to WOPR)
SELECT *
FROM Call
LEFT OUTER JOIN Phone_Book
ON (Call.phone_number = Phone_book.phone_number)
WHERE Phone_book.phone_number IS NULL
(ignoring that, as others have said, it's normally best to select just the columns you want, not '*
')
This isn't quite what you're looking for, but I've found it useful in similar circumstances.
I recently added the following to my $HOME/.bashrc
(something similar should be possible with shells other than bash):
if [ -f $HOME/.add-screen-to-history ] ; then
history -s 'screen -dr'
fi
I keep a screen
session running on one particular machine, and I've had problems with ssh
connections to that machine being dropped, requiring me to re-run screen -dr
every time I reconnect.
With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr
command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions
.
You might want to make the history -s
command unconditional.
This does require updating your $HOME/.bashrc
on each of the target systems, which might or might not make it unsuitable for your purposes.

I had the same question, the solutions proposed were almost working but they had some issue. In the end the regex I used is:
^(?!red|green|blue).*
I tested it in Javascript and .NET.
.* should't be placed inside the negative lookahead like this: ^(?!.*red|green|blue) or it would make the first element behave different from the rest (i.e. "anotherred" wouldn't be matched while "anothergreen" would)
You can use query string to pass value from one page to another..
1.pass the value using querystring
Response.Redirect("Default3.aspx?value=" + txt.Text + "& number="+n);
2.Retrive the value in the page u want by using any of these methods..
Method1:
string v = Request.QueryString["value"];
string n=Request.QueryString["number"];
Method2:
NameValueCollection v = Request.QueryString;
if (v.HasKeys())
{
string k = v.GetKey(0);
string n = v.Get(0);
if (k == "value")
{
lbltext.Text = n.ToString();
}
if (k == "value1")
{
lbltext.Text = "error occured";
}
}
NOTE:Method 2 is the fastest method.
To change button Radius, Color and Width I set like this:
self.myBtn.layer.cornerRadius = 10;
self.myBtn.layer.borderWidth = 1;
self.myBtn.layer.borderColor =[UIColor colorWithRed:189.0/255.0f green:189.0/255.0f blue:189.0/255.0f alpha:1.0].CGColor;
A thread is an execution context, which is all the information a CPU needs to execute a stream of instructions.
Suppose you're reading a book, and you want to take a break right now, but you want to be able to come back and resume reading from the exact point where you stopped. One way to achieve that is by jotting down the page number, line number, and word number. So your execution context for reading a book is these 3 numbers.
If you have a roommate, and she's using the same technique, she can take the book while you're not using it, and resume reading from where she stopped. Then you can take it back, and resume it from where you were.
Threads work in the same way. A CPU is giving you the illusion that it's doing multiple computations at the same time. It does that by spending a bit of time on each computation. It can do that because it has an execution context for each computation. Just like you can share a book with your friend, many tasks can share a CPU.
On a more technical level, an execution context (therefore a thread) consists of the values of the CPU's registers.
Last: threads are different from processes. A thread is a context of execution, while a process is a bunch of resources associated with a computation. A process can have one or many threads.
Clarification: the resources associated with a process include memory pages (all the threads in a process have the same view of the memory), file descriptors (e.g., open sockets), and security credentials (e.g., the ID of the user who started the process).
Presumably you're passing the arguments in on the command line as follows:
php /path/to/wwwpublic/path/to/script.php arg1 arg2
... and then accessing them in the script thusly:
<?php
// $argv[0] is '/path/to/wwwpublic/path/to/script.php'
$argument1 = $argv[1];
$argument2 = $argv[2];
?>
What you need to be doing when passing arguments through HTTP (accessing the script over the web) is using the query string and access them through the $_GET superglobal:
Go to http://yourdomain.com/path/to/script.php?argument1=arg1&argument2=arg2
... and access:
<?php
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
?>
If you want the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:
EDIT: as pointed out by Cthulhu in the comments, the most direct way to test which environment you're executing in is to use the PHP_SAPI constant. I've updated the code accordingly:
<?php
if (PHP_SAPI === 'cli') {
$argument1 = $argv[1];
$argument2 = $argv[2];
}
else {
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
}
?>
you can use always:
'C:/mydir'
this works both in linux and windows. Other posibility is
'C:\\mydir'
if you have problems with some names you can also try raw string literals:
r'C:\mydir'
however best practice is to use the os.path
module functions that always select the correct configuration for your OS:
os.path.join(mydir, myfile)
From python 3.4 you can also use the pathlib module. This is equivelent to the above:
pathlib.Path(mydir, myfile)
or
pathlib.Path(mydir) / myfile

If you want a quick and dirty one-liner query:
select * from information_schema.tables
You can run it directly in the Query tool without having to open psql.
(Other posts suggest nice more specific information_schema queries but as a newby, I am finding this one-liner query helps me get to grips with the table)
Here is a stripped down example, using as little HTML markup as possible.
The overlay is provided by the :before
pseudo element on the .content
container.
No z-index is required, :before
is naturally layered over the video element.
The .content
container is position: relative
so that the position: absolute
overlay is positioned in relation to it.
The overlay is stretched to cover the entire .content
div width with left / right / bottom
and left
set to 0
.
The width of the video is controlled by the width of its container with width: 100%
.content {
position: relative;
width: 500px;
margin: 0 auto;
padding: 20px;
}
.content video {
width: 100%;
display: block;
}
.content:before {
content: '';
position: absolute;
background: rgba(0, 0, 0, 0.5);
border-radius: 5px;
top: 0;
right: 0;
bottom: 0;
left: 0;
}

If you want it without the year:
DateTime.Now.ToString("MM/DD");
DateTime.ToString() has a lot of cool format strings:
Supported by SQL Server 2005 and later versions
SELECT CONVERT(VARCHAR(10), GETDATE(), 101)
+ ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
* See Microsoft's documentation to understand what the 101
and 108
style codes above mean.
Supported by SQL Server 2012 and later versions
SELECT FORMAT(GETDATE() , 'MM/dd/yyyy HH:mm:ss')
Result
Both of the above methods will return:
10/16/2013 17:00:20
You can use the to_pydatetime method to be more explicit:
In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)
In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)
It's also available on a DatetimeIndex:
In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')
In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
datetime.datetime(2011, 1, 11, 0, 0),
datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)
Visual Studio with PTVS could be an option for you: http://www.hanselman.com/blog/OneOfMicrosoftsBestKeptSecretsPythonToolsForVisualStudioPTVS.aspx
Off the top of my head:
GetType()
instead of typeof(Page)
in order to bind the script to your actual page class instead of the base class,Page.UniqueID
, which is not that meaningful since it's supposed to be used by named controls,PreRender
phase:protected void Page_PreRender(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this, GetType(), "YourUniqueScriptKey",
"alert('This pops up');", true);
}
I'd like to differ with marc_s on this, who wrote:
a XSD describes the DATA aspects e.g. of a webservice - the WSDL describes the FUNCTIONS of the web services (method calls). You cannot typically figure out the method calls from your data alone.
WSDL does not describe functions. WSDL defines a network interface, which itself is comprised of endpoints that get messages and then sometimes reply with messages. WSDL describes the endpoints, and the request and reply messages. It is very much message oriented.
We often think of WSDL as a set of functions, but this is because the web services tools typically generate client-side proxies that expose the WSDL operations as methods or function calls. But the WSDL does not require this. This is a side effect of the tools.
EDIT: Also, in the general case, XSD does not define data aspects of a web service. XSD defines the elements that may be present in a compliant XML document. Such a document may be exchanged as a message over a web service endpoint, but it need not be.
Getting back to the question I would answer the original question a little differently. I woudl say YES, it is possible to generate a WSDL file given a xsd file, in the same way it is possible to generate an omelette using eggs.
EDIT: My original response has been unclear. Let me try again. I do not suggest that XSD is equivalent to WSDL, nor that an XSD is sufficient to produce a WSDL. I do say that it is possible to generate a WSDL, given an XSD file, if by that phrase you mean "to generate a WSDL using an XSD file". Doing so, you will augment the information in the XSD file to generate the WSDL. You will need to define additional things - message parts, operations, port types - none of these are present in the XSD. But it is possible to "generate a WSDL, given an XSD", with some creative effort.
If the phrase "generate a WSDL given an XSD" is taken to imply "mechanically transform an XSD into a WSDL", then the answer is NO, you cannot do that. This much should be clear given my description of the WSDL above.
When generating a WSDL using an XSD file, you will typically do something like this (note the creative steps in this procedure):
Most of the WSDL is more or less boilerplate. It can look daunting, but that is mostly because of those scary and plentiful angle brackets, I've found.
Some have suggested that this is a long-winded manual process. Maybe. But this is how you can build interoperable services. You can also use tools for defining WSDL. Dynamically generating WSDL from code will lead to interop pitfalls.
You also can use
public boolean isDbConnected(Connection con) {
try {
return con != null && !con.isClosed();
} catch (SQLException ignored) {}
return false;
}
In python v3.x you should go to : Tools->Build System->New Build System
.
Then, it pop up the untitled.sublime-build window in sublime text editor.Enter setting as:
{
"cmd": ["path_to_the_python.exe","-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
To see the path, Type following in terminal as
:
python
>>> import sys
>>>print(sys.executable)
You can make more than one Build System but it should default save inside Packages of Sublime text with .sublime-build extension.
Then, select the new Build System and press cltr+b
or other based on your os.
Note that Josh's solution only works for a single element.
Arguably, "outer" HTML only really makes sense when you have a single element, but there are situations where it makes sense to take a list of HTML elements and turn them into markup.
Extending Josh's solution, this one will handle multiple elements:
(function($) {
$.fn.outerHTML = function() {
var $this = $(this);
if ($this.length>1)
return $.map($this, function(el){ return $(el).outerHTML(); }).join('');
return $this.clone().wrap('<div/>').parent().html();
}
})(jQuery);
Edit: another problem with Josh's solution fixed, see comment above.
If you want to check the number of insertions, deletions & commits, between two branches or commits.
using commit id's:
git log <commit-id>..<commit-id> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'
using branches:
git log <parent-branch>..<child-branch> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'
There is a statement you can issue at the module level:
Option Compare Text
This makes all "text comparisons" case insensitive. This means the following code will show the message "this is true":
Option Compare Text
Sub testCase()
If "UPPERcase" = "upperCASE" Then
MsgBox "this is true: option Compare Text has been set!"
End If
End Sub
See for example http://www.ozgrid.com/VBA/vba-case-sensitive.htm . I'm not sure it will completely solve the problem for all instances (such as the Application.Match
function) but it will take care of all the if a=b
statements. As for Application.Match
- you may want to convert the arguments to either upper case or lower case using the LCase
function.

You can modify a sheet via code by taking these actions
In code this would be:
Sub UnProtect_Modify_Protect()
ThisWorkbook.Worksheets("Sheet1").Unprotect Password:="Password"
'Unprotect
ThisWorkbook.ActiveSheet.Range("A1").FormulaR1C1 = "Changed"
'Modify
ThisWorkbook.Worksheets("Sheet1").Protect Password:="Password"
'Protect
End Sub
The weakness of this method is that if the code is interrupted and error handling does not capture it, the worksheet could be left in an unprotected state.
The code could be improved by taking these actions
The code to do this would be:
Sub Re-Protect_Modify()
ThisWorkbook.Worksheets("Sheet1").Protect Password:="Password", _
UserInterfaceOnly:=True
'Protect, even if already protected
ThisWorkbook.ActiveSheet.Range("A1").FormulaR1C1 = "Changed"
'Modify
End Sub
This code renews the protection on the worksheet, but with the ‘UserInterfaceOnly’ set to true. This allows VBA code to modify the worksheet, while keeping the worksheet protected from user input via the UI, even if execution is interrupted.
This setting is lost when the workbook is closed and re-opened. The worksheet protection is still maintained.
So the 'Re-protection' code needs to be included at the start of any procedure that attempts to modify the worksheet or can just be run once when the workbook is opened.
PLEASE do not use object as a class name:
public class MyObject //better to choose an appropriate name
{
string id;
DateTime date;
public string ID
{
get { return id; }
set { id = value; }
}
public DateTime Date
{
get { return date; }
set { date = value; }
}
}
You should implement INotifyPropertyChanged
for this class and of course call it on the Property setter. Otherwise changes are not reflected in your ui.
Your Viewmodel class/ dialogbox class should have a Property
of your MyObject
list. ObservableCollection<MyObject>
is the way to go:
public ObservableCollection<MyObject> MyList
{
get...
set...
}
In your xaml
you should set the Itemssource
to your collection of MyObject
. (the Datacontext
have to be your dialogbox class!)
<DataGrid ItemsSource="{Binding Source=MyList}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
<DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
</DataGrid.Columns>
</DataGrid>
Add a system variable named "node", with value of your node path. It solves my problem, hope it helps.
Since you've already received help on the query, I'll take a poke at your syntax question:
The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join
and on
clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.
Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:
select
count(*)
from Table1 as t1
join Table2 as t2
join Table3 as t3
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:
select
count(*)
from Table1 as t1
join Table3 as t3
join Table2 as t2
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.
To Restart service in Android O
or more ie OS >28 Use this code KOTLIN VERSION
1) Add permission in manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
2) Create a Class
and extend it with BroadcastReceiver
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.os.Build
import android.util.Log
import androidx.core.content.ContextCompat
class BootCompletedReceiver : BroadcastReceiver() {
override fun onReceive(context: Context, arg1: Intent?) {
Log.d("BootCompletedReceiver", "starting service...")
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
ContextCompat.startForegroundService(context, Intent(context, YourServiceClass::class.java))
} else {
context.startService(Intent(context, YourServiceClass::class.java))
}
}
}
3) Declare in Manifest file like this under application tag
<receiver android:name=".utils.BootCompletedReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />

Just discovered GenMyModel, an awesome UML modeler to design class diagram online
==
:In most programming languages, the comparison operator (==) checks, on the one hand, the data type and on the other hand the content of the variable for equality. The standard comparison operator (==) in PHP behaves differently. This tries to convert both variables into the same data type before the comparison and only then checks whether the content of these variables is the same. The following results are obtained:
<?php
var_dump( 1 == 1 ); // true
var_dump( 1 == '1' ); // true
var_dump( 1 == 2 ); // false
var_dump( 1 == '2' ); // false
var_dump( 1 == true ); // true
var_dump( 1 == false ); // false
?>
===
:This operator also checks the datatype of the variable and returns (bool)true only if both variables have the same content and the same datatype. The following would therefore be correct:
<?php
var_dump( 1 === 1 ); // true
var_dump( 1 === '1' ); // false
var_dump( 1 === 2 ); // false
var_dump( 1 === '2' ); // false
var_dump( 1 === true ); // false
var_dump( 1 === false ); // false
?>

The array has a Length
property that will give you the length of the array. Since the array indices are zero-based, the last item will be at Length - 1
.
string[] items = GetAllItems();
string lastItem = items[items.Length - 1];
int arrayLength = array.Length;
When declaring an array in C#, the number you give is the length of the array:
string[] items = new string[5]; // five items, index ranging from 0 to 4.
A couple of additional points re use of vector
here.
Unlike ArrayList
and Array
in Java, you don't need to do anything special to treat a vector
as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.
Unlike ArrayList
, a vector
can efficiently hold primitive types without encapsulation as a full-fledged object.
When removing items from a vector
, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.
Make sure if you store complex objects in the vector
that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.
Advice about reserve()
ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.
First I tried this code
const peopleSchema = new mongoose.Schema({
name: String,
friends: [
{
firstName: String,
lastName: String,
},
],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
name: "Yash Salvi",
notes: [
{
firstName: "Johnny",
lastName: "Johnson",
},
],
});
first.save();
const friendNew = {
firstName: "Alice",
lastName: "Parker",
};
People.findOneAndUpdate(
{ name: "Yash Salvi" },
{ $push: { friends: friendNew } },
function (error, success) {
if (error) {
console.log(error);
} else {
console.log(success);
}
}
);
But I noticed that only first friend (i.e. Johhny Johnson) gets saved and the objective to push array element in existing array of "friends" doesn't seem to work as when I run the code , in database in only shows "First friend" and "friends" array has only one element ! So the simple solution is written below
const peopleSchema = new mongoose.Schema({
name: String,
friends: [
{
firstName: String,
lastName: String,
},
],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
name: "Yash Salvi",
notes: [
{
firstName: "Johnny",
lastName: "Johnson",
},
],
});
first.save();
const friendNew = {
firstName: "Alice",
lastName: "Parker",
};
People.findOneAndUpdate(
{ name: "Yash Salvi" },
{ $push: { friends: friendNew } },
{ upsert: true }
);
Adding "{ upsert: true }" solved problem in my case and once code is saved and I run it , I see that "friends" array now has 2 elements ! The upsert = true option creates the object if it doesn't exist. default is set to false.
if it doesn't work use below snippet
People.findOneAndUpdate(
{ name: "Yash Salvi" },
{ $push: { friends: friendNew } },
).exec();
The easiest way to fix it (if you don't have many changes) is to copy your changes to another directory, delete the directory where your project is checked out, and checkout the project again.
Then copy your changes back in (don't copy any .svn folders) and commit, and continue.
You don't need pip
for installing Beautiful Soup - you can just download it and run python setup.py install
from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH
- if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install
)
However, you really should install pip
- see How to install pip on Windows for how to do that best (via @MartijnPieters comment)

onResume()
is one of the methods called throughout the activity lifecycle. onResume()
is the counterpart to onPause()
which is called anytime an activity is hidden from view, e.g. if you start a new activity that hides it. onResume()
is called when the activity that was hidden comes back to view on the screen.
You're question asks abou what method is used to restart an activity. onCreate()
is called when the activity is first created. In practice, most activities persist in the background through a series of onPause()
and onResume()
calls. An activity is only really "restarted" by onRestart()
if it is first fully stopped by calling onStop()
and then brought back to life. Thus if you are not actually stopping activities with onStop()
it is most likley you will be using onResume()
.
Read the android doc in the above link to get a better understanding of the relationship between the different lifestyle methods. Regardless of which lifecycle method you end up using the general format is the same. You must override the standard method and include your code, i.e. what you want the activity to do at that point, in the commented section.
@Override
public void onResume(){
//will be executed onResume
}
According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:
JavaFX/OpenJFX 8 - Rich client application platform for Java
You can install it via:
sudo apt-get install openjfx
It provides the following JAR files to the OpenJDK installation on Ubuntu systems:
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar
If you want to have sources available, for example for debugging, you can additionally install:
sudo apt-get install openjfx-source
[Note: edited to modernize ggplot syntax]
Your example is not reproducible since there is no ex1221new
(there is an ex1221
in Sleuth2
, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot
. One advantage is that ggplot
works with data.frame
s directly.
You can set the labels with xlab()
and ylab()
, or make it part of the scale_*.*
call.
library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
xlab("My x label") +
ylab("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area("Nitrogen") +
scale_x_continuous("My x label") +
scale_y_continuous("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs
function
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
labs(size= "Nitrogen",
x = "My x label",
y = "My y label",
title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
which gives an identical figure to the one above.
Selecting text in an element (akin to highlighting with your mouse)
:)
Using the accepted answer on that post, you can call the function like this:
$(function() {
$('#textareaId').click(function() {
SelectText('#textareaId');
});
});
There is a filetype option in the Google Drive API. You could, maybe, check if that resolves to a valid image. I'd look at an option where if the filetype gives me an invalid image, then get a new direct URL for the file. I haven't figured out exactly how to do this though, but maybe that's a path to try.

It depends on the product. A product could be implemented that (under the covers) converts all UPDATEs into a (transactionally wrapped) DELETE and INSERT. Provided the results are consistent with the UPDATE semantics.

I don't know about past versions of UITableView
protocols, but as of iOS 9, func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String?
is part of the UITableViewDataSource
protocol.
class ViewController: UIViewController {
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
}
}
extension ViewController: UITableViewDataSource {
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return "Section name"
}
}
You don't need to declare the delegate
to fill your table with data.
Use the random
module: http://docs.python.org/library/random.html
import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)
This samples the two values without replacement (so the two values are different).
To select data in numerical range you can use BETWEEN
which is inclusive.
SELECT JOB FROM MYTABLE WHERE ID BETWEEN 10 AND 15;
Java 13 added a method which does this: String#translateEscapes

This forum on MSDN tells you.
Form.Close()
sends the proper Windows messages to shut down the win32 window. During that process, if the form was not shown modally, Dispose is called on the form. Disposing the form frees up the unmanaged resources that the form is holding onto.If you do a
form1.Show()
orApplication.Run(new Form1())
, Dispose will be called whenClose()
is called.However, if you do
form1.ShowDialog()
to show the form modally, the form will not be disposed, and you'll need to callform1.Dispose()
yourself. I believe this is the only time you should worry about disposing the form yourself.
Put [] around any field names that had spaces (as Dreden says) and save your query, close it and reopen it.
Using Access 2016, I still had the error message on new queries after I added [] around any field names... until the Query was saved.
Once the Query is saved (and visible in the Objects' List), closed and reopened, the error message disappears. This seems to be a bug from Access.
There's also a really useful discussion about converting the array in place, In-place type conversion of a NumPy array. If you're concerned about copying your array (which is whatastype()
does) definitely check out the link.
how do I programmatically add an event to the user's calendar?
Which calendar?
Is there a common API they all share?
No, no more than there is a "common API they all share" for Windows calendar apps. There are some common data formats (e.g., iCalendar) and Internet protocols (e.g., CalDAV), but no common API. Some calendar apps don't even offer an API.
If there are specific calendar applications you wish to integrate with, contact their developers and determine if they offer an API. So, for example, the Calendar application from the Android open source project, that Mayra cites, offers no documented and supported APIs. Google has even explicitly told developers to not use the techniques outlined in the tutorial Mayra cites.
Another option is for you to add events to the Internet calendar in question. For example, the best way to add events to the Calendar application from the Android open source project is to add the event to the user's Google Calendar via the appropriate GData APIs.
UPDATE
Android 4.0 (API Level 14) added a CalendarContract
ContentProvider

svn merge -c -[rev num that deleted the file] http://<path to repository>
So an example:
svn merge -c -12345 https://svn.mysite.com/svn/repo/project/trunk
^ The negative is important
For TortoiseSVN (I think...)
That is completely untested, however.
Edited by OP: This works on my version of TortoiseSVN (the old kind without the next button)
The trick is to merge backwards. Kudos to sean.bright for pointing me in the right direction!
Edit: We are using different versions. The method I described worked perfectly with my version of TortoiseSVN.
Also of note is that if there were multiple changes in the commit you are reverse merging, you'll want to revert those other changes once the merge is done before you commit. If you don't, those extra changes will also be reversed.
var bordT = $('img').outerWidth() - $('img').innerWidth();
var paddT = $('img').innerWidth() - $('img').width();
var margT = $('img').outerWidth(true) - $('img').outerWidth();

var formattedPadd = paddT + 'px';
var formattedMarg = margT + 'px';

Solution posted by Cawas works perfectly with XCode4, too. However, there are some changes to IDE's UI, so you need to make some research to find Run Script :)

a = 10
b = 2
var mixed = (a,b) => a * b;
// OR
var mixed = (a,b) => { (any logic); return a * b };
console.log(mixed(a,b))
// 20
is there a way to disable it?
Yes, you only need to use the JSON_UNESCAPED_SLASHES
flag.
!important read before: https://stackoverflow.com/a/10210367/367456 (know what you're dealing with - know your enemy)
json_encode($str, JSON_UNESCAPED_SLASHES);
If you don't have PHP 5.4 at hand, pick one of the many existing functions and modify them to your needs, e.g. http://snippets.dzone.com/posts/show/7487 (archived copy).
<?php
/*
* Escaping the reverse-solidus character ("/", slash) is optional in JSON.

*/
$url = 'http://www.example.com/';
echo json_encode($url), "\n";
echo json_encode($url, JSON_UNESCAPED_SLASHES), "\n";
Example Output:

If you intend to use the times later to compute with, learn how to use the -f
option of /usr/bin/time
to output code that saves times. Here's some code I used recently to get and sort the execution times of a whole classful of students' programs:
fmt="run { date = '$(date)', user = '$who', test = '$test', host = '$(hostname)', times = { user = %U, system = %S, elapsed = %e } }"
/usr/bin/time -f "$fmt" -o $timefile command args...
I later concatenated all the $timefile
files and pipe the output into a Lua interpreter. You can do the same with Python or bash or whatever your favorite syntax is. I love this technique.
Another approach is to add a toString()
method to your Car
class and just let the toString()
method of ArrayList do all the work.
@Override
public String toString()
{
return "Car{" +
"make=" + make +
", registration='" + registration + '\'' +
'}';
}
You don't get one car per line in the output, but it is quick and easy if you just want to see what is in the array.
List<Car> cars = c1.getAll();
System.out.println(cars);
Output would be something like this:
[Car{make=FORD, registration='ABC 123'},
Car{make=TOYOTA, registration='ZYZ 999'}]
Order of arguments to java

Build cache is generated on application run time when a temporary file automatically generated in dart-tools folder, android folder and iOS folder. Clear command will delete the build tools and dart directories in flutter project so when we re-compile the project it will start from beginning. This command is mostly used when our project is showing debug error or running related error. In this answer we would Clear Build Cache in Flutter Android iOS App and Rebuild Project structure again.
Open your flutter project folder in Command Prompt or Terminal. and type flutter clean
command and press enter.
After executing flutter clean command we would see that it will delete the dart-tools
folder, android
folder and iOS
folder in our application with debug file. This might take some time depending upon your system speed to clean the project.

This did the trick for me. http://thecodeattic.wordpress.com/category/ssrs/. Go down to step 35 to see the error you are getting. Paraphrasing:
Once you're able to log in to YourServer/Reports as an administrator, click Home in the top-right corner, then Folder Settings and New Role Assignment. Enter your user name and check a box for each role you want to grant yourself. Finally, click OK. You should now be able to browse folders without launching your browser with elevated privileges.
Don't forget to set the security at the site level **AND ** at the folder level. I hope that helps.

With Android Studio 1.0 you have to use zipAlignEnabled true
In my experience storing all the settings in a database table is the best solution. Don't even worry about performance. Today's databases are fast and can easily store thousands columns in a table. I learned this the hard way - before I was serilizing/deserializing - nightmare. Storing it in local file or registry has one big problem - if you have to support your app and computer is off - user is not in front of it - there is nothing you can do.... if setings are in DB - you can changed them and viola not to mention that you can compare the settings....
This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

From Save MySQL query results into a text or CSV file:
MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other application which accepts data in CSV format.
Given a query such as
SELECT order_id,product_name,qty FROM orders
which returns three columns of data, the results can be placed into the file /tmp/orders.txt using the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.txt'
This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
In this example, each field will be enclosed in double quotes, the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:
"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95"
Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.
Syntax
SELECT Your_Column_Name
FROM Your_Table_Name
INTO OUTFILE 'Filename.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
Or you could try to grab the output via the client:
You could try executing the query from the your local client and redirect the output to a local file destination:
mysql -user -pass -e "select cols from table where cols not null" > /tmp/output
Hint: If you don't specify an absoulte path but use something like INTO OUTFILE 'output.csv'
or INTO OUTFILE './output.csv'
, it will store the output file to the directory specified by show variables like 'datadir';

http://callmenick.com/2014/02/18/create-an-animated-resizing-header-on-scroll/
This link has a great tutorial with source code that you can play with, showing how to make elements within the header smaller as well as the header itself.
The options have been all enumerated, I think. Choosing one may come down to a matter of the best style for your particular application, and in that vein, I want to offer one particular style I've found useful. In bash, variables and functions are not in the same namespace. So, treating the variable of the same name as the value of the function is a convention that I find minimizes name clashes and enhances readability, if I apply it rigorously. An example from real life:
UnGetChar=
function GetChar() {
# assume failure
GetChar=
# if someone previously "ungot" a char
if ! [ -z "$UnGetChar" ]; then
GetChar="$UnGetChar"
UnGetChar=
return 0 # success
# else, if not at EOF
elif IFS= read -N1 GetChar ; then
return 0 # success
else
return 1 # EOF
fi
}
function UnGetChar(){
UnGetChar="$1"
}
And, an example of using such functions:
function GetToken() {
# assume failure
GetToken=
# if at end of file
if ! GetChar; then
return 1 # EOF
# if start of comment
elif [[ "$GetChar" == "#" ]]; then
while [[ "$GetChar" != $'\n' ]]; do
GetToken+="$GetChar"
GetChar
done
UnGetChar "$GetChar"
# if start of quoted string
elif [ "$GetChar" == '"' ]; then
# ... et cetera
As you can see, the return status is there for you to use when you need it, or ignore if you don't. The "returned" variable can likewise be used or ignored, but of course only after the function is invoked.
Of course, this is only a convention. You are free to fail to set the associated value before returning (hence my convention of always nulling it at the start of the function) or to trample its value by calling the function again (possibly indirectly). Still, it's a convention I find very useful if I find myself making heavy use of bash functions.
As opposed to the sentiment that this is a sign one should e.g. "move to perl", my philosophy is that conventions are always important for managing the complexity of any language whatsoever.

For those who are using Visual Studio (2015 in my case)
Close your project in VS. Especially in big projects VS tends to freak out when merging using the UI.
Do the merge in command prompt.
git checkout target_branch
git merge source_branch
Then open the project in VS and go to Team Explorer -> Branch. Now there is a message that says Merge is pending and conflicting files are listed right below the message.
Click the conflicting file and you will have the option to Merge, Compare, Take Source, Take Target. The merge tool in VS is very easy to use.
if you want to get the index position of the outliers idx_list
will return it.
def reject_outliers(data, m = 2.):
d = np.abs(data - np.median(data))
mdev = np.median(d)
s = d/mdev if mdev else 0.
data_range = np.arange(len(data))
idx_list = data_range[s>=m]
return data[s<m], idx_list
data_points = np.array([8, 10, 35, 17, 73, 77])
print(reject_outliers(data_points))
after rejection: [ 8 10 35 17], index positions of outliers: [4 5]
Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.
Here are the commands to retrieve key value:
<key>
<key>
<key> <start> <end>
<key>
<key> <min> <max>
Use the TYPE
command to check the type of value a key is mapping to:
<key>
In Oracle 12c you can use the function STANDARD_HASH. It does not require any additional privileges.
select standard_hash('foo', 'MD5') from dual;
The dbms_obfuscation_toolkit is deprecated (see Note here). You can use DBMS_CRYPTO directly:
select rawtohex(
DBMS_CRYPTO.Hash (
UTL_I18N.STRING_TO_RAW ('foo', 'AL32UTF8'),
2)
) from dual;
Output:
ACBD18DB4CC2F85CEDEF654FCCC4A4D8
Add a lower function call if needed. More on DBMS_CRYPTO.
Yes, It should be alright to have both versions installed. It's actually pretty much expected nowadays. A lot of stuff is written in 2.7, but 3.5 is becoming the norm. I would recommend updating all your python to 3.5 ASAP, though.

Historically, it's been impossible to make these things disappear as they are user settings and not considered part of the page you have control over.
http://css-discuss.incutio.com/wiki/Print_Stylesheets#Print_headers.2Ffooters_and_print_margins
However, as of 2017, the @page at-rule has been standardized, which can be used to hide the page title and date in modern browsers:
@page { size: auto; margin: 0mm; }

EDIT: The other two answers make a good point. I'm assuming that you want to order them into some other structure, or in order to print them out.
"Best" can mean a number of different things. Do you mean "easiest," "fastest," "most efficient," "least code," "most readable?"
The most obvious approach is to loop through twice. On the first pass, order the values:
if(current_value > examined_value)
{
current_value = examined_value
(and then swap them, however you like)
}
Then on the second pass, alphabetize the words, but only if their values match.
if(current_value == examined_value)
{
(alphabetize the two)
}
Strictly speaking, this is a "bubble sort" which is slow because every time you make a swap, you have to start over. One "pass" is finished when you get through the whole list without making any swaps.
There are other sorting algorithms, but the principle would be the same: order by value, then alphabetize.
This is how its looks
Inside your Adapter
private int selectedPosition = -1;
And onBindViewHolder
@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
if (selectedPosition == position) {
holder.itemView.setSelected(true); //using selector drawable
holder.tvText.setTextColor(ContextCompat.getColor(holder.tvText.getContext(),R.color.white));
} else {
holder.itemView.setSelected(false);
holder.tvText.setTextColor(ContextCompat.getColor(holder.tvText.getContext(),R.color.black));
}
holder.itemView.setOnClickListener(v -> {
if (selectedPosition >= 0)
notifyItemChanged(selectedPosition);
selectedPosition = holder.getAdapterPosition();
notifyItemChanged(selectedPosition);
});
}
Thats it! As you can see i am just Notifying(updating) previous selected item and newly selected item
My Drawable set it as a background for recyclerview child views
<selector xmlns:android="http://schemas.android.com/apk/res/android">

ORIGINAL:
It's also possible to override the OPTIONS request (was only tested in Chrome):
app.config(['$httpProvider', function ($httpProvider) {
//Reset headers to avoid OPTIONS request (aka preflight)
$httpProvider.defaults.headers.common = {};
$httpProvider.defaults.headers.post = {};
$httpProvider.defaults.headers.put = {};
$httpProvider.defaults.headers.patch = {};
}]);
The simplest way to get equal height columns, without the ugly side effects that come along with absolute positioning, is to use the display: table
properties:
.div1 {
width:300px;
height: auto;
background-color: grey;
border:1px solid;
display: table;
}
.div2, .div3 {
display: table-cell;
}
.div2 {
width:150px;
height:auto;
background-color: #F4A460;
}
.div3 {
width:150px;
height:auto;
background-color: #FFFFE0;
}
Now, if your goal is to have .div2
so that it is only as tall as it needs to be to contain its content while .div3
is at least as tall as .div2
but still able to expand if its content makes it taller than .div2
, then you need to use flexbox. Flexbox support isn't quite there yet (IE10, Opera, Chrome. Firefox follows an old spec, but is following the current spec soon).
.div1 {
width:300px;
height: auto;
background-color: grey;
border:1px solid;
display: flex;
align-items: flex-start;
}
.div2 {
width:150px;
background-color: #F4A460;
}
.div3 {
width:150px;
background-color: #FFFFE0;
align-self: stretch;
}
Add another div
or img
to your main div
and blur that instead. jsfiddle
.blur {
background:url('http://i0.kym-cdn.com/photos/images/original/000/051/726/17-i-lol.jpg?1318992465') no-repeat center;
background-size:cover;
-webkit-filter: blur(13px);
-moz-filter: blur(13px);
-o-filter: blur(13px);
-ms-filter: blur(13px);
filter: blur(13px);
position:absolute;
width:100%;
height:100%;
}
Just Remove the "Target Framework 4.0" and close the bracket.

I find the following is the ideal display for listing what files changed per commit in a concise format :
git log --pretty=oneline --graph --name-status
Multiple attributes can be connected with an and
:
GroupMember.find_or_create_by_member_id_and_group_id(4, 7)
(use find_or_initialize_by
if you don't want to save the record right away)
Edit: The above method is deprecated in Rails 4. The new way to do it will be:
GroupMember.where(:member_id => 4, :group_id => 7).first_or_create
and
GroupMember.where(:member_id => 4, :group_id => 7).first_or_initialize
Edit 2: Not all of these were factored out of rails just the attribute specific ones.
https://github.com/rails/rails/blob/4-2-stable/guides/source/active_record_querying.md
Example
GroupMember.find_or_create_by_member_id_and_group_id(4, 7)
became
GroupMember.find_or_create_by(member_id: 4, group_id: 7)
Menu items file looks like

tools:context=".MainActivity">
<item
android:id="@+id/settings"
android:title="Setting"
app:showAsAction="never" />
<item
android:id="@+id/my_activity"
android:title="My Activity"
app:showAsAction="always"
android:icon="@android:drawable/btn_radio"/>
</menu>
Java code looks like
src/MainActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.my_activity) {
Intent intent1 = new Intent(this,MyActivity.class);
this.startActivity(intent1);
return true;
}
if (id == R.id.settings) {
Toast.makeText(this, "Setting", Toast.LENGTH_LONG).show();
return true;
}
return super.onOptionsItemSelected(item);
}
And add following code to your AndroidManifest.xml file
<activity
android:name=".MyActivity"
android:label="@string/app_name" >
</activity>
I hope it will help you.
That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).
If I am working on an API to draw shapes, I may want to use DirectX or graphic calls, or OpenGL. So, I will create an interface, which will abstract my implementation from what you call.
So you call a factory method: MyInterface i = MyGraphics.getInstance()
. Then, you have a contract, so you know what functions you can expect in MyInterface
. So, you can call i.drawRectangle
or i.drawCube
and know that if you swap one library out for another, that the functions are supported.
This becomes more important if you are using Dependency Injection, as then you can, in an XML file, swap implementations out.
So, you may have one crypto library that can be exported that is for general use, and another that is for sale only to American companies, and the difference is in that you change a config file, and the rest of the program isn't changed.
This is used a great deal with collections in .NET, as you should just use, for example, List
variables, and don't worry whether it was an ArrayList or LinkedList.
As long as you code to the interface then the developer can change the actual implementation and the rest of the program is left unchanged.
This is also useful when unit testing, as you can mock out entire interfaces, so, I don't have to go to a database, but to a mocked out implementation that just returns static data, so I can test my method without worrying if the database is down for maintenance or not.
In modern, supported browsers, you can simply do that in CSS with -
header{
position: sticky;
top: 0;
}
Note: The HTML structure is important while using position: sticky
, since it's make the element sticky relative to the parent. And the sticky positioning might not work with a single element made sticky within a parent.
Run the snippet below to check a sample implementation.
main{_x000D_
padding: 0;_x000D_
}_x000D_
header{_x000D_
position: sticky;_x000D_
top:0;_x000D_
padding:40px;_x000D_
background: lightblue;_x000D_
text-align: center;_x000D_
}_x000D_
_x000D_
content > div {_x000D_
height: 50px;_x000D_
}
_x000D_
<main>_x000D_
<header>_x000D_
This is my header_x000D_
</header>_x000D_
<content>_x000D_
<div>Some content 1</div>_x000D_
<div>Some content 2</div>_x000D_
<div>Some content 3</div>_x000D_
<div>Some content 4</div>_x000D_
<div>Some content 5</div>_x000D_
<div>Some content 6</div>_x000D_
<div>Some content 7</div>_x000D_
<div>Some content 8</div>_x000D_
</content>_x000D_
</main>
_x000D_
There is also a convenient shortcut to get all elements of the array starting with specified index. For example "${A[@]:1}" would be the "tail" of the array, that is the array without its first element.
version=4.7.1
A=( ${version//\./ } )
echo "${A[@]}" # 4 7 1
B=( "${A[@]:1}" )
echo "${B[@]}" # 7 1
I use a library called ExcelDataReader, you can find it on NuGet. Be sure to install both ExcelDataReader and the ExcelDataReader.DataSet extension (the latter provides the required AsDataSet method referenced below).
I encapsulated everything in one function, you can copy it in your code directly. Give it a path to CSV file, it gets you a dataset with one table.
public static DataSet GetDataSet(string filepath)
{
var stream = File.OpenRead(filepath);
try
{
var reader = ExcelReaderFactory.CreateCsvReader(stream, new ExcelReaderConfiguration()
{
LeaveOpen = false
});
var result = reader.AsDataSet(new ExcelDataSetConfiguration()
{
// Gets or sets a value indicating whether to set the DataColumn.DataType
// property in a second pass.
UseColumnDataType = true,
// Gets or sets a callback to determine whether to include the current sheet
// in the DataSet. Called once per sheet before ConfigureDataTable.
FilterSheet = (tableReader, sheetIndex) => true,
// Gets or sets a callback to obtain configuration options for a DataTable.
ConfigureDataTable = (tableReader) => new ExcelDataTableConfiguration()
{
// Gets or sets a value indicating the prefix of generated column names.
EmptyColumnNamePrefix = "Column",
// Gets or sets a value indicating whether to use a row from the
// data as column names.
UseHeaderRow = true,
// Gets or sets a callback to determine which row is the header row.
// Only called when UseHeaderRow = true.
ReadHeaderRow = (rowReader) =>
{
// F.ex skip the first row and use the 2nd row as column headers:
//rowReader.Read();
},
// Gets or sets a callback to determine whether to include the
// current row in the DataTable.
FilterRow = (rowReader) =>
{
return true;
},
// Gets or sets a callback to determine whether to include the specific
// column in the DataTable. Called once per column after reading the
// headers.
FilterColumn = (rowReader, columnIndex) =>
{
return true;
}
}
});
return result;
}
catch (Exception ex)
{
return null;
}
finally
{
stream.Close();
stream.Dispose();
}
}
While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event
argument to the setMaster
function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):
function AdminController($scope) {
$scope.setMaster = function(obj, $event){
console.log($event.target);
}
}
this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.
The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event
argument) would be:
<div ng-controller="AdminController">
<ul class="list-holder">
<li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
<a ng-click="setMaster(section)">{{section.name}}</a>
</li>
</ul>
<hr>
{{selected | json}}
</div>
where methods in the controller would look like this:
$scope.setMaster = function(section) {
$scope.selected = section;
}
$scope.isSelected = function(section) {
return $scope.selected === section;
}

Stan Lippman talked about this here. I thought it was interesting.
Summary: Stroustrup originally used class
to specify types in templates to avoid introducing a new keyword. Some in the committee worried that this overloading of the keyword led to confusion. Later, the committee introduced a new keyword typename
to resolve syntactic ambiguity, and decided to let it also be used to specify template types to reduce confusion, but for backward compatibility, class
kept its overloaded meaning.

The function pthread_mutex_lock()
either acquires the mutex for the calling thread or blocks the thread until the mutex can be acquired. The related pthread_mutex_unlock()
releases the mutex.
Think of the mutex as a queue; every thread that attempts to acquire the mutex will be placed on the end of the queue. When a thread releases the mutex, the next thread in the queue comes off and is now running.
A critical section refers to a region of code where non-determinism is possible. Often this because multiple threads are attempting to access a shared variable. The critical section is not safe until some sort of synchronization is in place. A mutex lock is one form of synchronization.
I was trying to do this on Drupal 7 with the " fb_likebox" module (https://drupal.org/project/fb_likebox). To get it to be responsive. Turns out I had to write my own Contrib module Variation and stripe out the width setting option. (the default height option didn't matter for me). Once I removed the width, I added the <div id="likebox-wrapper">
in the fb_likebox.tpl.php.
Here's my CSS to style it:
`#likebox-wrapper * {
width: 100% !important;
background: url('../images/block.png') repeat 0 0;
color: #fbfbfb;
-webkit-border-radius: 7px;
-moz-border-radius: 7px;
-o-border-radius: 7px;
border-radius: 7px;
border: 1px solid #DDD;}`

You want the mod operator.
The expression a Mod b is equivalent to the following formula:
a - (b * (a \ b))
Edited to add:
There are some special cases you may have to consider, because Excel is using floating point math (and returns a float
), which the VBA function returns an integer. Because of this, using mod
with floating-point numbers may require extra attention:
Excel's results may not correspond exactly with what you would predict; this is covered briefly here (see topmost answer) and at great length here.
As @André points out in the comments, negative numbers may round in the opposite direction from what you expect. The Fix()

The way you have it is fine but you could create a set of extension methods to make "a more elegant way to check for the 'NOT' instance."
public static bool Is<T>(this object myObject)
{
return (myObject is T);
}
public static bool IsNot<T>(this object myObject)
{
return !(myObject is T);
}
Then you could write:

Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.
And here's a table for typeof
To add some background, there are two data types in JavaScript:
An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.
An array can be considered to be an object with the following properties/keys:
Hope this helped shed more light on why typeof Array returns an object. Cheers!
Try it the other way:
var start_date = $("#fit_start_time").val(); //05-09-2013
var end_date = $("#fit_end_time").val(); //10-09-2013
var format='dd-MM-y';
var result= compareDates(start_date,format,end_date,format);
if(result==1)/// end date is less than start date
{
alert('End date should be greater than Start date');
}
OR:
if(new Date(start_date) >= new Date(end_date))
{
alert('End date should be greater than Start date');
}
Classes are simply blueprints to create objects from. The constructor is some code that are run every time you create an object. Therefor it does'nt make sense to have two constructors. What happens is that the second over write the first.
What you typically use them for is create variables for that object like this:
>>> class testing:
... def __init__(self, init_value):
... self.some_value = init_value
So what you could do then is to create an object from this class like this:
>>> testobject = testing(5)
The testobject will then have an object called some_value
that in this sample will be 5.
>>> testobject.some_value
5
But you don't need to set a value for each object like i did in my sample. You can also do like this:
>>> class testing:
... def __init__(self):
... self.some_value = 5
then the value of some_value will be 5 and you don't have to set it when you create the object.
>>> testobject = testing()
>>> testobject.some_value
5
the >>> and ... in my sample is not what you write. It's how it would look in pyshell...
0 will get printed.
As in C++ true refers to 1 and false refers to 0.
In case, you want to print false instead of 0,then you have to sets the boolalpha format flag for the str stream.
When the boolalpha format flag is set, bool values are inserted/extracted by their textual representation: either true or false, instead of integral values.
#include <iostream>
int main()
{
std::cout << std::boolalpha << false << std::endl;
}
output:
false
I think this answer is quite readable:
def month_delta(dt, delta):
year_delta, month = divmod(dt.month + delta, 12)
if month == 0:
# convert a 0 to december
month = 12
if delta < 0:
# if moving backwards, then it's december of last year
year_delta -= 1
year = dt.year + year_delta
return dt.replace(month=month, year=year)
for delta in range(-20, 21):
print(delta, "->", month_delta(datetime(2011, 1, 1), delta))

You can use sshpass for it. Below are the steps
sudo apt-get install sshpass
sshpass -p '#Password_For_remote_machine' scp /home/ubuntu/latest_build/abc.war #user@#RemoteIP:/var/lib/tomcat7/webapps

std::string the_string(c_string);
if(the_string.size() > max_length)
the_string.resize(max_length);
You can do this in XAML easily enough:

An easy way to reduce compilation time in larger C++ projects is to make a *.cpp include file that includes all the cpp files in your project and compile that. This reduces the header explosion problem to once. The advantage of this is that compilation errors will still reference the correct file.
For example, assume you have a.cpp, b.cpp and c.cpp.. create a file: everything.cpp:
#include "a.cpp"
#include "b.cpp"
#include "c.cpp"
Then compile the project by just making everything.cpp
You should definitely use this one.
from os.path import exists
if exists("file") == True:
print "File exists."
elif exists("file") == False:
print "File doesn't exist."
I Abstract Timer away and made it a separate class:
Timer.java
import android.os.Handler;
public class Timer {
IAction action;
Handler timerHandler = new Handler();
int delayMS = 1000;
public Timer(IAction action, int delayMS) {
this.action = action;
this.delayMS = delayMS;
}
public Timer(IAction action) {
this(action, 1000);
}
public Timer() {
this(null);
}
Runnable timerRunnable = new Runnable() {
@Override
public void run() {
if (action != null)
action.Task();
timerHandler.postDelayed(this, delayMS);
}
};
public void start() {
timerHandler.postDelayed(timerRunnable, 0);
}
public void stop() {
timerHandler.removeCallbacks(timerRunnable);
}
}
And Extract main action from Timer
class out as
IAction.java
public interface IAction {
void Task();
}
And I used it just like this:
MainActivity.java
public class MainActivity extends Activity implements IAction{
...
Timer timerClass;
@Override
protected void onCreate(Bundle savedInstanceState) {
...
timerClass = new Timer(this,1000);
timerClass.start();
...
}
...
int i = 1;
@Override
public void Task() {
runOnUiThread(new Runnable() {
@Override
public void run() {
timer.setText(i + "");
i++;
}
});
}
...
}
I Hope This Helps
all you need to do is right click on the jsp page in the browser, which might look like "localhost:8080/images.jpg, copy this and paste it where the image is getting generated
Simply write one line in the constructor:
setResizable(false);
This will make it impossible to resize the frame.
Bash4 supports this natively. Do not use grep

Had the same error but with a different scenario. I had my state as
this.state = {
date: new Date()
}
so when I was asking it in my Class Component I had
p>Date = {this.state.date}</p>
Instead of
p>Date = {this.state.date.toLocaleDateString()}</p>
I question the logic of raising a PropertyChanged
event on the second property when it's the first property that's changing. If the second properties value changes then the PropertyChanged
event could be raised there.
At any rate, the answer to your question is you should implement INotifyPropertyChange
. This interface contains the PropertyChanged
event. Implementing INotifyPropertyChanged
lets other code know that the class has the PropertyChanged
event, so that code can hook up a handler. After implementing INotifyPropertyChange
, the code that goes in the if statement of your OnPropertyChanged
is:
if (PropertyChanged != null)
PropertyChanged(new PropertyChangedEventArgs("MySecondProperty"));

&& ; || are logical operators.... short circuit
& ; | are boolean logical operators.... Non-short circuit
Moving to differences in execution on expressions. Bitwise operators evaluate both sides irrespective of the result of left hand side. But in the case of evaluating expressions with logical operators, the evaluation of the right hand expression is dependent on the left hand condition.
For Example:
int i = 25;
int j = 25;
if(i++ < 0 && j++ > 0)
System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);
This will print i=26 ; j=25, As the first condition is false the right hand condition is bypassed as the result is false anyways irrespective of the right hand side condition.(short circuit)
int i = 25;
int j = 25;
if(i++ < 0 & j++ > 0)
System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);
But, this will print i=26; j=26,

you can reduce the legend size setting:
plt.legend(labelspacing=y, handletextpad=x,fontsize)
labelspacing is the vertical space between each label.
handletextpad is the distance between the actual legend and your label.

I think Microsoft guide for ASP.NET Identity is a good start.
Note:
If you do not use AccountController and wan't to reset your password, use Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
. If you dont have the same OwinContext you need to create a new DataProtectorTokenProvider
like the one OwinContext
uses. By default look at App_Start -> IdentityConfig.cs
. Should look something like new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
.
Could be created like this:
Without Owin:
[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
var db = new ApplicationDbContext();
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
var provider = new DpapiDataProtectionProvider("SampleAppName");
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
provider.Create("SampleTokenName"));
var email = "[email protected]";
var user = new ApplicationUser() { UserName = email, Email = email };
var identityUser = manager.FindByEmail(email);
if (identityUser == null)
{
manager.Create(user);
identityUser = manager.FindByEmail(email);
}
var token = manager.GeneratePasswordResetToken(identityUser.Id);
return Ok(HttpUtility.UrlEncode(token));
}
[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
var db = new ApplicationDbContext();
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
var provider = new DpapiDataProtectionProvider("SampleAppName");
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
provider.Create("SampleTokenName"));
var email = "[email protected]";
var identityUser = manager.FindByEmail(email);
var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
return Ok(result);
}
With Owin:
[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
var email = "[email protected]";
var user = new ApplicationUser() { UserName = email, Email = email };
var identityUser = manager.FindByEmail(email);
if (identityUser == null)
{
manager.Create(user);
identityUser = manager.FindByEmail(email);
}
var token = manager.GeneratePasswordResetToken(identityUser.Id);
return Ok(HttpUtility.UrlEncode(token));
}
[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
var email = "[email protected]";
var identityUser = manager.FindByEmail(email);
var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
return Ok(result);
}
The DpapiDataProtectionProvider
and DataProtectorTokenProvider
needs to be created with the same name for a password reset to work. Using Owin for creating the password reset token and then creating a new DpapiDataProtectionProvider
with another name won't work.

I would also like to add something from me.
Other possible syntax to call functions with the ternary operator, would be:
(condition ? fn1 : fn2)();
It can be handy if you have to pass the same list of parameters to both functions, so you have to write them only once.
(condition ? fn1 : fn2)(arg1, arg2, arg3, arg4, arg5);
You can use the ternary operator even with member function names, which I personally like very much to save space:
$('.some-element')[showThisElement ? 'addClass' : 'removeClass']('visible');
or
$('.some-element')[(showThisElement ? 'add' : 'remove') + 'Class']('visible');
Another example:
var addToEnd = true; //or false
var list = [1,2,3,4];
list[addToEnd ? 'push' : 'unshift'](5);
Just use the Cells function and loop thru columns. Cells(Row,Column)
Because 2
isn't an array, it's a number. Numbers have no length.
Perhaps you meant to write testvar.length
; this is also undefined, since objects (created using the { ... }
notation) do not have a length.
Only arrays have a length property:
var testvar = [ ];
testvar[1] = 2;
testvar[2] = 3;
alert(testvar.length); // 3
Note that Javascript arrays are indexed starting at 0
and are not necessarily sparse (hence why the result is 3 and not 2 -- see this answer for an explanation of when the array will be sparse and when it won't).
If the table is InnoDB, see http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html -- it uses consistent-read (no-locking mode) for SELECTs "that do not specify FOR UPDATE or LOCK IN SHARE MODE if the innodb_locks_unsafe_for_binlog option is set and the isolation level of the transaction is not set to SERIALIZABLE. Thus, no locks are set on rows read from the selected table".

Here are a few additional tips on testing rules that may ease the debugging for users on shared hosting
When testing a new rule, add a condition to only execute it with a fake
user-agent that you will use for your requests. This way it will not affect anyone else on your site.
e.g
#protect with a fake user agent
RewriteCond %{HTTP_USER_AGENT} ^my-fake-user-agent$
#Here is the actual rule I am testing
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteRule ^ http://www.domain.com%{REQUEST_URI} [L,R=302]
If you are using Firefox, you can use the User Agent Switcher to create the fake user agent string and test.
I have seen so many posts where people are still testing their rules and they are using 301's. DON'T.
If you are not using suggestion 1 on your site, not only you, but anyone visiting your site at the time will be affected by the 301.
Remember that they are permanent, and aggressively cached by your browser. Use a 302 instead till you are sure, then change it to a 301.
If your rule does not work and it looks right to you, and you were not using suggestions 1 and 2, then re-test after clearing your browser cache or while in private browsing.
Use a HTTP capture tool like Fiddler to see the actual HTTP traffic between your browser and the server.
While others might say that your site does not look right
, you could instead see and report that all of the images, css and js are returning 404 errors
, quickly narrowing down the problem.
While others will report that you started at URL A and ended at URL C
, you will be able to see that they started at URL A, were 302 redirected to URL B and 301 redirected to URL C
. Even if URL C was the ultimate goal, you will know that this is bad for SEO and needs to be fixed.
You will be able to see cache headers that were set on the server side, replay requests, modify request headers to test ....

int statusCode = response.getStatusLine().getStatusCode();
out.println("Response Code :"+ statusCode);
Below is my solution for downloading multiple files depending on some list which consists of some ids and looking up in database, files will be determined and ready for download - if those exist. I am calling C# MVC action for each file using Ajax.
And Yes, like others said, it is possible to do it in jQuery Ajax. I did it with Ajax success and I am always sending response 200.
So, this is the key:
success: function (data, textStatus, xhr) {
And this is my code:
var i = 0;
var max = 0;
function DownloadMultipleFiles() {
if ($(".dataTables_scrollBody>tr.selected").length > 0) {
var list = [];
showPreloader();
$(".dataTables_scrollBody>tr.selected").each(function (e) {
var element = $(this);
var orderid = element.data("orderid");
var iscustom = element.data("iscustom");
var orderlineid = element.data("orderlineid");
var folderPath = "";
var fileName = "";
list.push({ orderId: orderid, isCustomOrderLine: iscustom, orderLineId: orderlineid, folderPath: folderPath, fileName: fileName });
});
i = 0;
max = list.length;
DownloadFile(list);
}
}
Then calling:
function DownloadFile(list) {
$.ajax({
url: '@Url.Action("OpenFile","OrderLines")',
type: "post",
data: list[i],
xhrFields: {
responseType: 'blob'
},
beforeSend: function (xhr) {
xhr.setRequestHeader("RequestVerificationToken",
$('input:hidden[name="__RequestVerificationToken"]').val());
},
success: function (data, textStatus, xhr) {
// check for a filename
var filename = "";
var disposition = xhr.getResponseHeader('Content-Disposition');
if (disposition && disposition.indexOf('attachment') !== -1) {
var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
var matches = filenameRegex.exec(disposition);
if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
var a = document.createElement('a');
var url = window.URL.createObjectURL(data);
a.href = url;
a.download = filename;
document.body.append(a);
a.click();
a.remove();
window.URL.revokeObjectURL(url);
}
else {
getErrorToastMessage("Production file for order line " + list[i].orderLineId + " does not exist");
}
i = i + 1;
if (i < max) {
DownloadFile(list);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
},
complete: function () {
if(i===max)
hidePreloader();
}
});
}

As long as you return response 200, success in Ajax can work with it, you can check if file actually exist or not as the line below in this case would be false and you can inform user about that:
if (disposition && disposition.indexOf('attachment') !== -1) {
I just use contentsMargin
to fix the aspect ratio.
#pragma once
#include <QLabel>
class AspectRatioLabel : public QLabel
{
public:
explicit AspectRatioLabel(QWidget* parent = nullptr, Qt::WindowFlags f = Qt::WindowFlags());
~AspectRatioLabel();
public slots:
void setPixmap(const QPixmap& pm);
protected:
void resizeEvent(QResizeEvent* event) override;
private:
void updateMargins();
int pixmapWidth = 0;
int pixmapHeight = 0;
};
#include "AspectRatioLabel.h"
AspectRatioLabel::AspectRatioLabel(QWidget* parent, Qt::WindowFlags f) : QLabel(parent, f)
{
}
AspectRatioLabel::~AspectRatioLabel()
{
}
void AspectRatioLabel::setPixmap(const QPixmap& pm)
{
pixmapWidth = pm.width();
pixmapHeight = pm.height();
updateMargins();
QLabel::setPixmap(pm);
}
void AspectRatioLabel::resizeEvent(QResizeEvent* event)
{
updateMargins();
QLabel::resizeEvent(event);
}
void AspectRatioLabel::updateMargins()
{
if (pixmapWidth <= 0 || pixmapHeight <= 0)
return;
int w = this->width();
int h = this->height();
if (w <= 0 || h <= 0)
return;
if (w * pixmapHeight > h * pixmapWidth)
{
int m = (w - (pixmapWidth * h / pixmapHeight)) / 2;
setContentsMargins(m, 0, m, 0);
}
else
{
int m = (h - (pixmapHeight * w / pixmapWidth)) / 2;
setContentsMargins(0, m, 0, m);
}
}
Works perfectly for me so far. You're welcome.
I imagine that these might possibly be changed with some styling options. But as far as default values go, these are taken from my version of Excel 2010 which should have the defaults.
"Bad" Red Font: 156, 0, 6; Fill: 255, 199, 206
"Good" Green Font: 0, 97, 0; Fill: 198, 239, 206
"Neutral" Yellow Font: 156, 101, 0; Fill: 255, 235, 156
Found an alternative way to download cocoapods is to download one of the snapshots available here. It is a bit old but the .bz2 compressed file was much faster to download. Once I had downloaded it, I copied it over to ~/.cocoapods/repos/
and then I unzipped it using bzip2 -dk *.bz2
.
The unzipping took a while and once it was over, I changed the extension of the newly uncompressed file to .tar and did tar xvf *.tar
to unzip that. This will show the list of files being created and will also take a while.
Finally when I ran pod repo list
while inside the project folder, it showed the master folder had been added as a repo. Because I still kept getting an error that it was unable to find the specification for the pod I was looking for, I went to the master folder and did git fetch
and then git merge
. The git fetch took the longest, about an hour at 50 KB/s. I used fetch and merge instead of pull, as I was having issues with it, i.e. fatal: the remote end hung up unexpectedly
. It is now up to date and I was able to get the pod I wanted.
I tested the performance of FileInputStream vs. FileChannel for decoding base64 encoded files. In my experients I tested rather large file and traditional io was alway a bit faster than nio.
FileChannel might have had an advantage in prior versions of the jvm because of synchonization overhead in several io related classes, but modern jvm are pretty good at removing unneeded locks.
Move excel variables which are global declare in your form to local like in my form I have:
Dim xls As New MyExcel.Interop.Application
Dim xlb As MyExcel.Interop.Workbook
above two lines were declare global in my form so i moved these two lines to local function and now tool is working fine.
There is no standard way to do this. You need to use 3rd party tools such as ApexSQL Restore or SQL Virtual Restore. These tools don’t really read the backup file directly. They get SQL Server to “think” of backup files as if these were live databases.
Passing arguments by bundle is restricted to some data types. But you can transfer any data to your fragment this way:
In your fragment create a public method like this
public void passData(Context context, List<LexItem> list, int pos) {
mContext = context;
mLexItemList = list;
mIndex = pos;
}
and in your activity call passData() with all your needed data types after instantiating the fragment
WebViewFragment myFragment = new WebViewFragment();
myFragment.passData(getApplicationContext(), mLexItemList, index);
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add(R.id.my_fragment_container, myFragment);
ft.addToBackStack(null);
ft.commit();
Remark: My fragment extends "android.support.v4.app.Fragment", therefore I have to use "getSupportFragmentManager()". Of course, this principle will work also with a fragment class extending "Fragment", but then you have to use "getFragmentManager()".
I think your question is similar to this thread: JDBC Pagination which contains solutions for your need.
In particular, for PostgreSQL, you can use the LIMIT and OFFSET keywords in your request: http://www.petefreitag.com/item/451.cfm
PS: In Java code, I suggest you to use PreparedStatement instead of simple Statements: http://download.oracle.com/javase/tutorial/jdbc/basics/prepared.html
You shouldn't really be de-encrypting passwords.
You should be encrypting the password entered into your application and comparing against the encrypted password from the database.
Edit - and if this is because the password has been forgotten, then setup a mechanism to create a new password.
I had the same problem when I tried from inside Visual Studio and "git status" in shell showed no problem. But I managed to push the local changes with "git push" via shell.
Usually a good place to start when you run into problems is the manual. The page on configuring email explains that there's a big difference between the PHP mail command running on MSWindows and on every other operating system; it's a good idea when posting a question to provide relevant information on how that part of your system is configured and what operating system it is running on.
Your PHP is configured to talk to an SMTP server - the default for an MSWindows machine, but either you have no MTA installed or it's blocking connections. While for a commercial website running your own MTA robably comes quite high on the list of things to do, it is not a trivial exercise - you really need to know what you're doing to get one configured and running securely. It would make a lot more sense in your case to use a service configured and managed by someone else.
Since you'll be connecting to a remote MTA using a gmail address, then you should probably use Gmail's server; you will need SMTP authenticaton and probably SSL support - neither of which are supported by the mail() function in PHP. There's a simple example here using swiftmailer with gmail or here's an example using phpmailer
Use animation-fill-mode: forwards;
animation-fill-mode: forwards;
The element will retain the style values that is set by the last keyframe (depends on animation-direction and animation-iteration-count).
Note: The @keyframes rule is not supported in Internet Explorer 9 and earlier versions.
Working example

Using base graphics, the standard way to do this is to use axes=FALSE, then create your own axes using Axis (or axis). For example,
x <- 1:20
y <- runif(20)
plot(x, y, axes=FALSE, frame.plot=TRUE)
Axis(side=1, labels=FALSE)
Axis(side=2, labels=FALSE)
The lattice equivalent is
library(lattice)
xyplot(y ~ x, scales=list(alternating=0))
PowerShell is pretty common these days so I use it often as a quick way to invoke C# since that has functions for pretty much everything:
@echo off
set pathToResolve=%~dp0\..\SomeFile.txt
for /f "delims=" %%a in ('powershell -Command "[System.IO.Path]::GetFullPath( '%projectDirMc%' )"') do @set resolvedPath=%%a
echo Resolved path: %resolvedPath%
It's a bit slow, but the functionality gained is hard to beat unless without resorting to an actual scripting language.
We can bypass execution policy in a nice way (inside command prompt):
type file.ps1 | powershell -command -
Or inside powershell:
gc file.ps1|powershell -c -
Above example is also correct, but i provide simple example:
var fs = require("fs");
var sampleObject = {
name: 'pankaj',
member: 'stack',
type: {
x: 11,
y: 22
}
};
fs.writeFile("./object.json", JSON.stringify(sampleObject, null, 4), (err) => {
if (err) {
console.error(err);
return;
};
console.log("File has been created");
});
As a good practice recommended by Apple, it's good for the delegate (which is a protocol, by definition), to conform to NSObject
protocol.
@protocol MyDelegate <NSObject>
...
@end
& to create optional methods within your delegate (i.e. methods which need not necessarily be implemented), you can use the @optional
annotation like this :
@protocol MyDelegate <NSObject>
...
...
// Declaration for Methods that 'must' be implemented'
...
...
@optional
...
// Declaration for Methods that 'need not necessarily' be implemented by the class conforming to your delegate
...
@end
So when using methods that you have specified as optional, you need to (in your class) check with respondsToSelector
if the view (that is conforming to your delegate) has actually implemented your optional method(s) or not.
import java.io.IOException;
class ExamTest{
public static void main(String args[]) throws IOException{
int sn=System.in.read();
System.out.println(sn);
}
}
If you want get char input you have to cast like this: char sn=(char) System.in.read()
The value byte is returned as int in the range 0 to 255. However, unlike in other languages’ methods, System.in.read()
reads only a byte at a time.
With the new animation API that was introduced in Android 3.0 (Honeycomb) it is very simple to create such animations.
Sliding a View
down by a distance:
view.animate().translationY(distance);
You can later slide the View
back to its original position like this:
view.animate().translationY(0);
You can also easily combine multiple animations. The following animation will slide a View
down by its height and fade it in at the same time:
// Prepare the View for the animation
view.setVisibility(View.VISIBLE);
view.setAlpha(0.0f);
// Start the animation
view.animate()
.translationY(view.getHeight())
.alpha(1.0f)
.setListener(null);
You can then fade the View
back out and slide it back to its original position. We also set an AnimatorListener
so we can set the visibility of the View
back to GONE
once the animation is finished:
view.animate()
.translationY(0)
.alpha(0.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
view.setVisibility(View.GONE);
}
});

Try to remove the tabIndex property of the modal, when your input/textbox is open. Set it back to what ever it was, when you close input/textbox. This would resolve the issue irrespective bootstrap version, and without compromising the user experience flow.
Alternative solution for rows of NA
s using janitor
package
myData %>% remove_empty("rows")
An alternative, you can also use fopen
$params = array('http' => array(
'method' => 'POST',
'content' => 'toto=1&tata=2'
));
$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if (!$fp)
{
throw new Exception("Problem with $sUrl, $php_errormsg");
}
$response = @stream_get_contents($fp);
if ($response === false)
{
throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}
An open source application called "Startup Creator" configures Windows Startup by creating a script while giving an easy to use interface. Utilizing powerful VBScript, it allows applications or services to start up at timed delay intervals, always in the same order. These scripts are automatically placed in your startup folder, and can be opened back up to allow modifications in the future.
You can "fake it" by creating a new HttpContext
like this:
I've taken that code and put it on an static helper class like so:
public static HttpContext FakeHttpContext()
{
var httpRequest = new HttpRequest("", "http://example.com/", "");
var stringWriter = new StringWriter();
var httpResponse = new HttpResponse(stringWriter);
var httpContext = new HttpContext(httpRequest, httpResponse);
var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
new HttpStaticObjectsCollection(), 10, true,
HttpCookieMode.AutoDetect,
SessionStateMode.InProc, false);
httpContext.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
BindingFlags.NonPublic | BindingFlags.Instance,
null, CallingConventions.Standard,
new[] { typeof(HttpSessionStateContainer) },
null)
.Invoke(new object[] { sessionContainer });
return httpContext;
}
Or instead of using reflection to construct the new HttpSessionState
instance, you can just attach your HttpSessionStateContainer
to the HttpContext
(as per Brent M. Spell's comment):
SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);
and then you can call it in your unit tests like:
HttpContext.Current = MockHelper.FakeHttpContext();
Its hard to give you a good answer, without seeing the html that you are actually using.
Are you outputting a doctype / using standards mode rendering? Without actually being able to look into a html repro, that would be my first guess for a html interpretation difference between firefox and internet explorer.
You're trying to access a JSON, not JSONP.
Notice the difference between your source:
And actual JSONP (a wrapping function):
Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.
If you installed xcode and upgraded to mountain lion, or you don't have the latest command line tools installed, or you have zsh or other shells, you can shortcut to some of the embedded tools in the developer directory with:
xcrun make
Unordered lists are often created with the intent of using them as a menu, but an li
list item is text. Because the list li
item is text, the mouse pointer will not be an arrow, but an "I cursor". Users are accustomed to seeing a pointing finger for a mouse pointer when something is clickable. Using an anchor tag a
inside of the li
tag causes the mouse pointer to change to a pointing finger. The pointing finger is a lot better for using the list as a menu.
<ul id="menu">
<li><a href="#">Menu Item 1</a></li>
<li><a href="#">Menu Item 2</a></li>
<li><a href="#">Menu Item 3</a></li>
<li><a href="#">Menu Item 4</a></li>
</ul>
If the list is being used for a menu, and doesn't need a link, then a URL doesn't need to be designated. But the problem is that if you leave out the href
attribute, text in the <a>
tag is seen as text, and therefore the mouse pointer is back to an I-cursor. The I-cursor might make the user think that the menu item is not clickable. Therefore, you still need an href
, but you don't need a link to anywhere.
You could use lots of div
or p
tags for a menu list, but the mouse pointer would be an I-cursor for them also.
You could use lots of buttons stacked on top of each other for a menu list, but the list seems to be preferable. And that's probably why the href="#"
that points to nowhere is used in anchor tags inside of list tags.
You can set the pointer style in CSS, so that is another option. The href="#"
to nowhere might just be the lazy way to set some styling.
