Since c
is holding the address of an integer pointer, its type should be int**
:
int **c;
c = &a;
The entire program becomes:
#include <stdio.h>
int main(){
int b=10;
int *a;
a=&b;
int **c;
c=&a;
printf("%d",(**c)); //successfully prints 10
return 0;
}
code bit should read:
var my_json;
$.getJSON(my_url, function(json) {
my_json = json;
});

The process of using SCP to copy files from a local machine to an AWS EC2 Linux instance is covered step-by-step (including the points mentioned below) in this video.
To correct this particular issue with using SCP:
You need to specify the correct Linux user. From Amazon:
Your private key must not be publicly visible. Run the following command so that only the root user can read the file.
chmod 400 /path/to/yourKeyFile.pem

The docker run
command has a --ulimit
flag you can use this flag to set the open file limit in your docker container.
Run the following command when spinning up your container to set the open file limit.
docker run --ulimit nofile=<softlimit>:<hardlimit>
the first value before the colon indicates the soft file limit and the value after the colon indicates the hard file limit. you can verify this by running your container in interactive mode and executing the following command in your containers shell ulimit -n

headers.append("Authorization", "Bearer " + t;
var body = JSON.stringify(user);

Virtual Method:
Virtual means we CAN override it.
Virtual Function has an implementation. When we inherit the class we can override the virtual function and provide our own logic.
Abstract Method
Abstract means we MUST override it.
An abstract function has no implementation and must be in an abstract class.
It can only be declared. This forces the derived class to provide the implementation of it.
An abstract member is implicitly virtual. The abstract can be called as pure virtual in some of the languages.
public abstract class BaseClass
{
protected abstract void xAbstractMethod();
public virtual void xVirtualMethod()
{
var x = 3 + 4;
}
}
Simplified example (with counter):

.List(i, 1) = Company_name
i = i + 1
end with
Make sure to start the counter with 0, not 1 to fill up a listbox.

It's not like choosing your new wife or car.
I'd never run any of these on a production server, so, to run just some quick tests any of them are equally good.
In operating systems like Ubuntu python comes preinstalled. So the default version is python 2.7 you can confirm the version by typing below command in your terminal
python -V
if you installed it but didn't set default version you will see
python 2.7
in terminal. I will tell you how to set the default python version in Ubuntu.
A simple safe way would be to use an alias. Place this into ~/.bashrc or ~/.bash_aliases file:
alias python=python3
After adding the above in the file, run the command below:
source ~/.bash_aliases
or source ~/.bashrc
now check python version again using python -V
if python version 3.x.x one, then the error is in your syntax like using print with parenthesis. change it to
test = input("enter the test")
print(test)
The c# function, as expressed by Kyle Rozendo:
string DecimalPlaceNoRounding(double d, int decimalPlaces = 2)

d = d / Math.Pow(10, decimalPlaces);
return string.Format("{0:N" + Math.Abs(decimalPlaces) + "}", d);
}

You can do it server-side with nodejs.
Check out the popular Nodemailer package. There are plenty of transports and plugins for integrating with services like AWS SES and SendGrid!
The following example uses SES transport (Amazon SES):
let nodemailer = require("nodemailer");
let aws = require("aws-sdk");
let transporter = nodemailer.createTransport({
SES: new aws.SES({ apiVersion: "2010-12-01" })
});

I was searching for a way to bind to multiple key events - specifically, Shift+Enter - but couldn't find any good resources online. But after logging the keydown binding
<textarea (keydown)=onKeydownEvent($event)></textarea>
I discovered that the keyboard event provided all of the information I needed to detect Shift+Enter. Turns out that $event
returns a fairly detailed KeyboardEvent.
onKeydownEvent(event: KeyboardEvent): void {
if (event.keyCode === 13 && event.shiftKey) {
// On 'Shift+Enter' do this...
}
}
There also flags for the CtrlKey, AltKey, and MetaKey (i.e. Command key on Mac).
No need for the KeyEventsPlugin, JQuery, or a pure JS binding.

The usual way is to use zip()
:
for x, y in zip(a, b):
# x is from a, y is from b
This will stop when the shorter of the two iterables a
and b
is exhausted. Also worth noting: itertools.izip()
(Python 2 only) and itertools.izip_longest()
(itertools.zip_longest()
in Python 3).
np.convolve()
takes one dimension array. You need to check the input and convert it into 1D.
You can use the np.ravel()
, to convert the array to one dimension.
The advantage is Dependency Injection (DI). It means outsourcing the task of object creation.Let me explain with an example.
public interface Lunch
{
public void eat();
}
public class Buffet implements Lunch
{
public void eat()
{
// Eat as much as you can
}
}
public class Plated implements Lunch
{
public void eat()
{
// Eat a limited portion
}
}
Now in my code I have a class LunchDecide as follows:
public class LunchDecide {
private Lunch todaysLunch;
public LunchDecide(){
this.todaysLunch = new Buffet(); // choose Buffet -> eat as much as you want
//this.todaysLunch = new Plated(); // choose Plated -> eat a limited portion
}
}
In the above class, depending on our mood, we pick Buffet() or Plated(). However this system is tightly coupled. Every time we need a different type of Object, we need to change the code. In this case, commenting out a line ! Imagine there are 50 different classes used by 50 different people. It would be a hell of a mess. In this case, we need to Decouple the system. Let's rewrite the LunchDecide class.
public class LunchDecide {
private Lunch todaysLunch;
public LunchDecide(Lunch todaysLunch){
this.todaysLunch = todaysLunch
}
}
Notice that instead of creating an object using new keyword we passed the reference to an object of Lunch Type as a parameter to our constructor. Here, object creation is outsourced. This code can be wired either using Xml config file (legacy) or Java Annotations (modern). Either way, the decision on which Type of object would be created would be done there during runtime. An object would be injected by Xml into our code - Our Code is dependent on Xml for that job. Hence, Dependency Injection (DI). DI not only helps in making our system loosely coupled, it simplifies writing of Unit tests since it allows dependencies to be mocked. Last but not the least, DI streamlines Aspect Oriented Programming (AOP) which leads to further decoupling and increase of modularity. Also note that above DI is Constructor Injection. DI can be done by Setter Injection as well - same plain old setter method from encapsulation.

As an addition to @C??? answer, make sure the title of the tooltip has not already been set manually in the HTML element. In my case, the span class for the tooltip already had a fixed tittle text, because of this my JQuery function $('[data-toggle="tooltip"]').prop('title', 'your new title');
did not work.
When I removed the title attribute in the HTML span class, the jQuery was working.
So:
<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
<span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top" title="this is my pre-set title text"></span>
</span>
Should becode:
<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
<span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top"></span>
</span>
Here is an example that replaces all instances of 1 or more white space characters in a column with an underscore using regular expression -

Get image size with jQuery

console.log('image size:', $(e.target).width(), $(e.target).height());
},
}
});
}
or
function getMeta(url){
$('<img/>',{
src: url,
}).on({
load: (e) => {
console.log('image size:', $(e.target).width(), $(e.target).height());
},
});

Beware: some phones have 2 sdcards , an internal fixed one and a removable card. You can find the name of the last one via a standard app:"Mijn Bestanden" ( in English: "MyFiles" ? ) When I open this app (item:all files) the path of the open folder is "/sdcard" ,scrolling down there is an entry "external-sd" , clicking this opens the folder "/sdcard/external_sd/" . Suppose I want to open a text-file "MyBooks.txt" I would use something as :

Why does the error mention tuples?
Others have explained that the problem was the missing ,
, but the final mystery is why does the error message talk about tuples?
The reason is that your:
["pennies", '2.5', '50.0', '.01']
["nickles", '5.0', '40.0', '.05']
can be reduced to:
[][1, 2]
as mentioned by 6502 with the same error.
But then __getitem__
, which deals with []
resolution, converts object[1, 2]
to a tuple:
class C(object):
def __getitem__(self, k):
return k
# Single argument is passed directly.
assert C()[0] == 0
# Multiple indices generate a tuple.
assert C()[0, 1] == (0, 1)
and the implementation of __getitem__
for the list built-in class cannot deal with tuple arguments like that.
More examples of __getitem__

Maybe it is sufficient if you wrap a Card
around the Widget
and play a bit with the elevation
prop.
I use this trick to make my ListTile
look nicer in Lists
.
For your code it could look like this:
return Card(
elevation: 3, // PLAY WITH THIS VALUE
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
// ... MORE OF YOUR CODE
],
),
);
I had this problem when I installed something that created a user environment PATH variable. My TeamCity build agent was running as a service under my own username and it found the user PATH variable instead of the machine PATH variable. With the wrong path variable, it couldn't find much of anything and gave this error.

Same thing, Just start the table name with #
or ##
:
CREATE TABLE #TemporaryTable -- Local temporary table - starts with single #
(
Col1 int,
Col2 varchar(10)
....
);
CREATE TABLE ##GlobalTemporaryTable -- Global temporary table - note it starts with ##.
(
Col1 int,
Col2 varchar(10)
....
);
Temporary table names start with #
or ##
- The first is a local temporary table and the last is a global temporary table.
Here is one of many articles describing the differences between them.

I've came through a case recently where I've needed check value of checkbox when user clicked on button. The only proper way to do so is to use prop()

this worked in my case maybe someone will need it.
When I've tried .attr(':checked')
it returned checked

returned value of attribute value

Changing the binding information in my web.config (or app.config) - while a "hack" in my view, allows you to move forward with your project after a NuGet package update whacks your application and gives you the System.Net.Http error.

I have had to do this several times and have researched many different solutions.
The solution I find in most elegant and easy to accomplish can be implemented as such.
the interface will contain signatures of any members you wish to call.
public interface IExampleProxy
{
string HelloWorld( string name );
}
Its important to keep this project clean and lite. It is a project that both AppDomain
's can reference and will allow us to not reference the Assembly
we wish to load in seprate domain from our client assembly.
AppDomain
.This project as with the client proj will reference the proxy proj and you will implement the interface.
public interface Example : MarshalByRefObject, IExampleProxy
{
public string HelloWorld( string name )
{
return $"Hello '{ name }'";
}
}
AppDomain
.So, now we create a new AppDomain
. Can specify the base location for assembly references. Probing will check for dependent assemblies in GAC and in current directory and the AppDomain
base loc.
// set up domain and create
AppDomainSetup domaininfo = new AppDomainSetup
{
ApplicationBase = System.Environment.CurrentDirectory
};
Evidence adevidence = AppDomain.CurrentDomain.Evidence;
AppDomain exampleDomain = AppDomain.CreateDomain("Example", adevidence, domaininfo);
// assembly ant data names
var assemblyName = "<AssemblyName>, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null|<keyIfSigned>";
var exampleTypeName = "Example";
// Optional - get a reflection only assembly type reference
var @type = Assembly.ReflectionOnlyLoad( assemblyName ).GetType( exampleTypeName );
// create a instance of the `Example` and assign to proxy type variable
IExampleProxy proxy= ( IExampleProxy )exampleDomain.CreateInstanceAndUnwrap( assemblyName, exampleTypeName );
// Optional - if you got a type ref
IExampleProxy proxy= ( IExampleProxy )exampleDomain.CreateInstanceAndUnwrap( @type.Assembly.Name, @type.Name );
// call any members you wish
var stringFromOtherAd = proxy.HelloWorld( "Tommy" );
// unload the `AppDomain`
AppDomain.Unload( exampleDomain );
if you need to, there are a ton of different ways to load an assembly. You can use a different way with this solution. If you have the assembly qualified name then I like to use the CreateInstanceAndUnwrap
since it loads the assembly bytes and then instantiates your type for you and returns an object
that you can simple cast to your proxy type or if you not that into strongly-typed code you could use the dynamic language runtime and assign the returned object to a dynamic
typed variable then just call members on that directly.
This allows to load an assembly that your client proj doesnt have reference to in a seperate AppDomain
and call members on it from client.
The key is to either make sure you code either derives MarshalByRefObject
or is serializable.
`MarshalByRefObject will allow you to configure the lifetime of the domain its in. Example, say you want the domain to destroy if the proxy hasnt been called in 20 minutes.
Note that the beauty of std::reverse is that it works with char *

Have you tried:
#!/usr/local/bin/php
I.e. without the -q
part? That's what the error message "Could not open input file: -q" means. The first argument to php
if it doesn't look like an option is the name of the PHP file to execute, and -q
is CGI only.
EDIT: A couple of (non-related) tips:
?>
. In fact, it is often better not to.STDIN
to fopen("php://stdin", "r")
. You can use that instead of opening "php://stdin"
a second time: $fd = STDIN;
You can use plt.subplots_adjust
to change the spacing between the subplots (source)
call signature:
subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)
The parameter meanings (and suggested defaults) are:
left = 0.125 # the left side of the subplots of the figure
right = 0.9 # the right side of the subplots of the figure
bottom = 0.1 # the bottom of the subplots of the figure
top = 0.9 # the top of the subplots of the figure
wspace = 0.2 # the amount of width reserved for blank space between subplots
hspace = 0.2 # the amount of height reserved for white space between subplots
The actual defaults are controlled by the rc file
Something like this should solve your problem:
$.getDocHeight = function(){
var D = document;
return Math.max(Math.max(D.body.scrollHeight, D.documentElement.scrollHeight), Math.max(D.body.offsetHeight, D.documentElement.offsetHeight), Math.max(D.body.clientHeight, D.documentElement.clientHeight));
};
alert( $.getDocHeight() );
Ps: Call that function every time you need it, the alert is for testing purposes..
As iEamin said in his answer, HTML 5 does now support this. The link he gave, http://www.html5rocks.com/en/tutorials/file/dndfiles/ , is excellent. Here is a minimal sample based on the samples at that site, but see that site for more thorough examples.
Add an onchange
event listener to your HTML:
<input type="file" onchange="onFileSelected(event)">
Make an image tag with an id (I'm specifying height=200
to make sure the image isn't too huge onscreen):
<img id="myimage" height="200">
Here is the JavaScript of the onchange
event listener. It takes the File
object that was passed as event.target.files[0]
, constructs a FileReader
to read its contents, and sets up a new event listener to assign the resulting data:
URL to the img
tag:
function onFileSelected(event) {
var selectedFile = event.target.files[0];

According to the error message, you declared myLoc
as a pointer to an NSInteger (NSInteger *myLoc
) rather than an actual NSInteger (NSInteger myLoc
). It needs to be the latter.
Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.
foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){
System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
foreach(Type type in asm.GetTypes()){
//PROPERTIES
foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
if (property.CanRead){
Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);
}
}
//METHODS
var methods = type.GetMethods();
foreach (System.Reflection.MethodInfo method in methods){
Response.Write("<br><b>" + an.ToString() + "." + type.ToString() + "." + method.Name + "</b>");
foreach (System.Reflection.ParameterInfo param in method.GetParameters())
{
Response.Write("<br><i>Param=" + param.Name.ToString());
Response.Write("<br> Type=" + param.ParameterType.ToString());
Response.Write("<br> Position=" + param.Position.ToString());
Response.Write("<br> Optional=" + param.IsOptional.ToString() + "</i>");

I had the same issue.. and you don't need to add a physical column.. cuz now you will have to maintain it.. what you can do is add a generic column in the select query:
EX:
select tb1.col1, tb1.col2, tb1.col3 ,
(
select 'Match' from table2 as tbl2
where tbl1.col1 = tbl2.col1 and tab1.col2 = tbl2.col2
)
from myTable as tbl1
I used to do the same until I started using libraries that are compiled differently depending on the environment such as PyCrypto. My PyCrypto mac wouldn't work on Cygwin wouldn't work on Ubuntu.
It becomes an utter nightmare to manage the repository.
Either way I found it easier to manage the pip freeze & a requirements file than having it all in git. It's cleaner too since you get to avoid the commit spam for thousands of files as those libraries get updated...
I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater
.
Before we get started see what LayoutInflater.inflate()
parameters look like:
R.layout.main_page
)attachToRoot
is true
), or else simply an object that provides a set of LayoutParams
values for root of the returned hierarchy (if attachToRoot
is false
.)attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams
for the root view in the XML.
Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot
is true
, this is root; otherwise it is the root of the inflated XML file.
Now for the sample layout and code.
Main layout (main.xml
):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml
):
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="25dp"
android:layout_height="25dp"
android:background="#ff0000"
android:text="red" />
Now LayoutInflater
is used with several variations of call parameters
public class InflaterTest extends Activity {
private View view;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ViewGroup parent = (ViewGroup) findViewById(R.id.container);
// result: layout_height=wrap_content layout_width=match_parent
view = LayoutInflater.from(this).inflate(R.layout.red, null);
parent.addView(view);
// result: layout_height=100 layout_width=100
view = LayoutInflater.from(this).inflate(R.layout.red, null);
parent.addView(view, 100, 100);
// result: layout_height=25dp layout_width=25dp
// view=textView due to attachRoot=false
view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
parent.addView(view);
// result: layout_height=25dp layout_width=25dp
// parent.addView not necessary as this is already done by attachRoot=true
// view=root due to parent supplied as hierarchy root and attachRoot=true
view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
}
}
The actual results of the parameter variations are documented in the code.
SYNOPSIS: Calling LayoutInflater
without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null
and attachRoot=true
does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()
).
The calling convention you most likely would like to use is therefore this one:
loadedView = LayoutInflater.from(context)
.inflate(R.layout.layout_to_load, parent, false);
To help with layout issues, the Layout Inspector is highly recommended.

Use the above link
private void btnopen_Click(object sender, EventArgs e){
OpenFileDialog openFileDialog1 = new OpenFileDialog();
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK){
axAcroPDF1.src = openFileDialog1.FileName;
}
}
Could you not just try it?
myContent = '<div id="test">Hello <span>world!</span></div>';
console.log($(myContent).text()); //Prints "Hello world!"
Note that you need to wrap the string in a jQuery object, otherwise it won't have a text
method obviously.
I think you can use the nrows
parameter. From the docs:
nrows : int, default None
Number of rows of file to read. Useful for reading pieces of large files
which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):
In [1]: import pandas as pd
In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
In [3]: len(z)
Out[3]: 20
In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s
Use the traceback module:
import sys
import traceback
try:
assert True
assert 7 == 7
assert 1 == 2
# many more statements like this
except AssertionError:
_, _, tb = sys.exc_info()
traceback.print_tb(tb) # Fixed format
tb_info = traceback.extract_tb(tb)
filename, line, func, text = tb_info[-1]
print('An error occurred on line {} in statement {}'.format(line, text))
exit(1)
Key Points:
ngModel in angular2 is valid only if the FormsModule is available as a part of your AppModule.
ng-model
is syntatically wrong.
So, to fix your error.
Step 1: Importing FormsModule
import {FormsModule} from '@angular/forms'
Step 2: Add it to imports array of your AppModule as
imports :[ ... , FormsModule ]
Step 3: Change ng-model
as ngModel with banana boxes as
<input id="name" type="text" [(ngModel)]="name" />
Note: Also, you can handle the two way databinding separately as well as below
<input id="name" type="text" [ngModel]="name" (ngModelChange)="valueChange($event)"/>
valueChange(value){
}
Does <img src="/path/to/pic.jpg" style="max-width:XXXpx; max-height:YYYpx;" >
help?
Browser will take care of keeping aspect ratio intact.
i.e max-width
kicks in when image width is greater than height and its height will be calculated proportionally. Similarly max-height
will be in effect when height is greater than width.
You don't need any jQuery or javascript for this.
Supported by ie7+ and other browsers (http://caniuse.com/minmaxwh).
it is quite simple...
var obj = {_x000D_
"set1": [1, 2, 3],_x000D_
"set2": [4, 5, 6, 7, 8],_x000D_
"set3": [9, 10, 11, 12]_x000D_
};_x000D_
_x000D_
jQuery.each(obj, function(i, val) {_x000D_
console.log(i); // "set1"_x000D_
console.log(val); // [1, 2, 3]_x000D_
});
_x000D_

You should use the .End(xlup)
but instead of using 65536 you might want to use:
sheetvar.Rows.Count
That way it works for Excel 2007 which I believe has more than 65536 rows
If, like me, what you usually want is to overwrite the contents of the working directory with that of the stashed files, and you still get a conflict, then what you want is to resolve the conflict using git checkout --theirs -- .
from the root.
After that, you can git reset
to bring all the changes from the index to the working directory, since apparently in case of conflict the changes to non-conflicted files stay in the index.
You may also want to run git stash drop [<stash name>]
afterwards, to get rid of the stash, because git stash pop
doesn't delete it in case of conflicts.
This comes in useful when you have global variables. You declare the existence of global variables in a header, so that each source file that includes the header knows about it, but you only need to “define” it once in one of your source files.
To clarify, using extern int x;
tells the compiler that an object of type int
called x
exists somewhere. It's not the compilers job to know where it exists, it just needs to know the type and name so it knows how to use it. Once all of the source files have been compiled, the linker will resolve all of the references of x
to the one definition that it finds in one of the compiled source files. For it to work, the definition of the x
variable needs to have what's called “external linkage”, which basically means that it needs to be declared outside of a function (at what's usually called “the file scope”) and without the static
keyword.
#ifndef HEADER_H
#define HEADER_H
// any source file that includes this will be able to use "global_x"
extern int global_x;
void print_global_x();
#endif
#include "header.h"
// since global_x still needs to be defined somewhere,
// we define it (for example) in this source file
int global_x;
int main()
{
//set global_x here:
global_x = 5;
print_global_x();
}
#include <iostream>
#include "header.h"
void print_global_x()
{
//print global_x here:
std::cout << global_x << std::endl;
}
In format function your can use timestamp_format function. Example, if the format is YYYYMMDD you can do it :
select TIMESTAMP_FORMAT(yourcolumnchar, 'YYYYMMDD') as YouTimeStamp
from yourtable
you can then adapt then format with elements format foundable here
On this web page, I see that:
"Remember that the dot is not a metacharacter inside a character class, so we do not need to escape it with a backslash."
So I guess the escaping of it is unnecessary...
GroupBy using in Hibernate
This is the resulting code
public Map getStateCounts(final Collection ids) {
HibernateSession hibernateSession = new HibernateSession();
Session session = hibernateSession.getSession();
Criteria criteria = session.createCriteria(DownloadRequestEntity.class)
.add(Restrictions.in("id", ids));
ProjectionList projectionList = Projections.projectionList();
projectionList.add(Projections.groupProperty("state"));
projectionList.add(Projections.rowCount());
criteria.setProjection(projectionList);
List results = criteria.list();
Map stateMap = new HashMap();
for (Object[] obj : results) {
DownloadState downloadState = (DownloadState) obj[0];
stateMap.put(downloadState.getDescription().toLowerCase() (Integer) obj[1]);
}
hibernateSession.closeSession();
return stateMap;
}
I made use of mysqlfrm
which is a great tool which generates table creation sql code from .frm files. I was getting this nasty table not found error although tables were being listed. Thus I used this tool to regenerate the tables. In ubuntu you need to install this as:
sudo apt install mysql-utilities
then,
mysqlfrm --diagnostic mysql/db_name/ > db_name.sql
Create a new database and then you can use,
mysql -u username -p < db_name.sql
However, this will give you the tables but not the data. In my case this was enough.
In all that cases, only works in Chrome and IE, I added the following code to solve that:
var key = (window.event) ? e.keyCode : e.which;
and I tested the key value on if keycode equals 13
$('body').on('keydown', 'input, select, textarea', function (e) {
var self = $(this)
, form = self.parents('form:eq(0)')
, focusable
, next
;
var key = (window.event) ? e.keyCode : e.which;
if (key == 13) {
focusable = form.find('input,a,select,button,textarea').filter(':visible');
next = focusable.eq(focusable.index(this) + 1);
if (next.length) {
next.focus();
} else {
focusable.click();
}
return false;
}
});
A Window object is just what it sounds like: its a new Window
for your application. You should use it when you want to pop up an entirely new window. I don't often use more than one Window
in WPF because I prefer to put dynamic content in my main Window that changes based on user action.
A Page is a page inside your Window. It is mostly used for web-based systems like an XBAP, where you have a single browser window and different pages can be hosted in that window. It can also be used in Navigation Applications like sellmeadog said.
A UserControl is a reusable user-created control that you can add to your UI the same way you would add any other control. Usually I create a UserControl
when I want to build in some custom functionality (for example, a CalendarControl
), or when I have a large amount of related XAML code, such as a View
when using the MVVM design pattern.
When navigating between windows, you could simply create a new Window
object and show it
var NewWindow = new MyWindow();
newWindow.Show();
but like I said at the beginning of this answer, I prefer not to manage multiple windows if possible.
My preferred method of navigation is to create some dynamic content area using a ContentControl
, and populate that with a UserControl
containing whatever the current view is.
<Window x:Class="MyNamespace.MainWindow" ...>
<DockPanel>
<ContentControl x:Name="ContentArea" />
</DockPanel>
</Window>
and in your navigate event you can simply set it using
ContentArea.Content = new MyUserControl();
But if you're working with WPF, I'd highly recommend the MVVM design pattern. I have a very basic example on my blog that illustrates how you'd navigate using MVVM, using this pattern:
<Window x:Class="SimpleMVVMExample.ApplicationView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:SimpleMVVMExample"
Title="Simple MVVM Example" Height="350" Width="525">
<Window.Resources>
<DataTemplate DataType="{x:Type local:HomeViewModel}">
<local:HomeView /> <!-- This is a UserControl -->
</DataTemplate>
<DataTemplate DataType="{x:Type local:ProductsViewModel}">
<local:ProductsView /> <!-- This is a UserControl -->
</DataTemplate>
</Window.Resources>
<DockPanel>
<!-- Navigation Buttons -->
<Border DockPanel.Dock="Left" BorderBrush="Black"
BorderThickness="0,0,1,0">
<ItemsControl ItemsSource="{Binding PageViewModels}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Name}"
Command="{Binding DataContext.ChangePageCommand,
RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
CommandParameter="{Binding }"
Margin="2,5"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Border>
<!-- Content Area -->
<ContentControl Content="{Binding CurrentPageViewModel}" />
</DockPanel>
</Window>
This below worked for me:
SELECT count(*)
INTO @exist
FROM information_schema.columns
WHERE table_schema = 'mydatabase'
and COLUMN_NAME = 'mycolumn'
AND table_name = 'mytable' LIMIT 1;
set @query = IF(@exist <= 0, 'ALTER TABLE mydatabase.`mytable` ADD COLUMN `mycolumn` MEDIUMTEXT NULL',
'select \'Column Exists\' status');
prepare stmt from @query;
EXECUTE stmt;
Persist should be called only on new entities, while merge
is meant to reattach detached entities.
If you're using the assigned generator, using merge
instead of persist
can cause a redundant SQL statement.
Also, calling merge for managed entities is also a mistake since managed entities are automatically managed by Hibernate, and their state is synchronized with the database record by the dirty checking mechanism upon flushing the Persistence Context.

e.preventDefault();_x000D_

Try pressing ctrl+s somewhere.
_x000D_
This is an up-to-date version of @AlanBellows's answer, replacing which
with key
. It also works even with Chrome's capital key glitch (where if you press Ctrl+S it sends capital S instead of s). Works in all modern browsers.
Copy isn't useless if you imagine the use case to copy some values into an existing collection. I.e. you want to overwrite existing elements instead of inserting.
An example: a = [1,2,3,4,5] b = [2,2,2,2,3,3,3,3,3,4,4,4,] a.copy(b) = [1,2,3,4,5,3,3,3,3,4,4,4]
However I'd expect a copy method that would take additional parameters for the start index of the source and target collection, as well as a parameter for count.
See Java BUG 6350752
This also works with nested dicts and makes sure that dicts which are appended later behave the same:
class DotDict(dict):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# Recursively turn nested dicts into DotDicts
for key, value in self.items():
if type(value) is dict:
self[key] = DotDict(value)
def __setitem__(self, key, item):
if type(item) is dict:
item = DotDict(item)
super().__setitem__(key, item)
__setattr__ = __setitem__
__getattr__ = dict.__getitem__
Remove existing origin and add new origin to your project directory

You might want to use insert
method. You can find the documentation for the Tkinter Entry Widget here.
This script inserts a text into Entry
. The inserted text can be changed in command
parameter of the Button.
from tkinter import *
def set_text(text):
e.delete(0,END)
e.insert(0,text)
return
win = Tk()
e = Entry(win,width=10)
e.pack()
b1 = Button(win,text="animal",command=lambda:set_text("animal"))
b1.pack()
b2 = Button(win,text="plant",command=lambda:set_text("plant"))
b2.pack()
win.mainloop()
It depends on the type of data you need access to. If you have some kind of data pool that needs to persist across Activity
s then Erich's answer is the way to go. If you just need to pass a few objects from one activity to another then you can have them implement Serializable
and pass them in the extras of the Intent
to start the new Activity
.
Next time, use a single "alter table" statement to update the primary key.
alter table xx drop primary key, add primary key(k1, k2, k3);
To fix things:
create table fixit (user_2, user_1, type, timestamp, n, primary key( user_2, user_1, type) );
lock table fixit write, user_interactions u write, user_interactions write;
insert into fixit
select user_2, user_1, type, max(timestamp), count(*) n from user_interactions u
group by user_2, user_1, type
having n > 1;
delete u from user_interactions u, fixit
where fixit.user_2 = u.user_2
and fixit.user_1 = u.user_1
and fixit.type = u.type
and fixit.timestamp != u.timestamp;
alter table user_interactions add primary key (user_2, user_1, type );
unlock tables;
The lock should stop further updates coming in while your are doing this. How long this takes obviously depends on the size of your table.
The main problem is if you have some duplicates with the same timestamp.

I have found that in Java 1.6.0_32 the normal method to pretty print an XML string (using a Transformer with a null or identity xslt) does not behave as I would like if tags are merely separated by whitespace, as opposed to having no separating text. I tried using <xsl:strip-space elements="*"/>
in my template to no avail. The simplest solution I found was to strip the space the way I wanted using a SAXSource and XML filter. Since my solution was for logging I also extended this to work with incomplete XML fragments. Note the normal method seems to work fine if you use a DOMSource but I did not want to use this because of the incompleteness and memory overhead.
public static class WhitespaceIgnoreFilter extends XMLFilterImpl
{
@Override
public void ignorableWhitespace(char[] arg0,
int arg1,
int arg2) throws SAXException
{
//Ignore it then...
}
@Override
public void characters( char[] ch,
int start,
int length) throws SAXException
{
if (!new String(ch, start, length).trim().equals(""))
super.characters(ch, start, length);
}
}
public static String prettyXML(String logMsg, boolean allowBadlyFormedFragments) throws SAXException, IOException, TransformerException
{
TransformerFactory transFactory = TransformerFactory.newInstance();
transFactory.setAttribute("indent-number", new Integer(2));
Transformer transformer = transFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
StringWriter out = new StringWriter();
XMLReader masterParser = SAXHelper.getSAXParser(true);
XMLFilter parser = new WhitespaceIgnoreFilter();
parser.setParent(masterParser);
if(allowBadlyFormedFragments)
{
transformer.setErrorListener(new ErrorListener()
{
@Override
public void warning(TransformerException exception) throws TransformerException
{
}
@Override
public void fatalError(TransformerException exception) throws TransformerException
{
}
@Override
public void error(TransformerException exception) throws TransformerException
{
}
});
}
try
{
transformer.transform(new SAXSource(parser, new InputSource(new StringReader(logMsg))), new StreamResult(out));
}
catch (TransformerException e)
{
if(e.getCause() != null && e.getCause() instanceof SAXParseException)
{
if(!allowBadlyFormedFragments || !"XML document structures must start and end within the same entity.".equals(e.getCause().getMessage()))
{
throw e;
}
}
else
{
throw e;
}
}
out.flush();
return out.toString();
}
Final working solution:
public static String getFileName(Uri uri) {
try {
String path = uri.getLastPathSegment();
return path != null ? path.substring(path.lastIndexOf("/") + 1) : "unknown";
} catch (Exception e) {
e.printStackTrace();
}
return "unknown";
}

My guess would be that while you run eclipse itself with JDK 1.6, it's actually configured with a different default jre.
See Window->preferences->java->Installed JREs
and make sure that the checked JRE is 1.6
.
If the default JRE is indeed 1.6, chances are that it's a project specific setting. See that the project is configured to use the right JRE.
If more precisely, you should use this condition:
if (array_search(__FILE__, get_included_files()) === 0) {
echo 'direct access';
}
else {
echo 'included';
}
get_included_files() returns indexed array containing names of all included files (if file is beign executed then it was included and its name is in the array). So, when the file is directly accessed, its name is the first in the array, all other files in the array were included.
I did this, also with jQuery:
$('input[type=search]').on('focus', function(){
// replace CSS font-size with 16px to disable auto zoom on iOS
$(this).data('fontSize', $(this).css('font-size')).css('font-size', '16px');
}).on('blur', function(){
// put back the CSS font-size
$(this).css('font-size', $(this).data('fontSize'));
});
Of course, some other elements in the interface may have to be adapted if this 16px
font-size breaks the design.
dt
is nullable
you need to access its Value
if (datetime.HasValue)
dt = datetime.Value;
It is important to remember that it can be NULL
. That is why the nullable
struct has the HasValue
property that tells you if it is NULL
or not.
You can also use the null-coalescing operator
??
to assign a default value
dt = datetime ?? DateTime.Now;
This will assign the value on the right if the value on the left is NULL
If you want something that does not break the relative design try this:
body .modal {
width: 90%; /* desired relative width */
left: 5%; /* (100%-width)/2 */
/* place center */
margin-left:auto;
margin-right:auto;
}
As, @Marco Johannesen says, the "body" before the selector is so that it takes a higher priority than the default.
Changing the content of the .git/config file helps as Alex said above. I experienced the same problem and I think it was because I changed my Github username. The local files could not be updated with the changes. So perhaps anytime you change your username you might consider running
git remote add origin your_ssh_link_from_github
I hope this helps ;)
Use this tool (uses the new apksigner from Google):
https://github.com/patrickfav/uber-apk-signer
Disclaimer: Im the developer :)
You need to generate a keystore once and use it to sign your unsigned
apk.
Use the keytool
provided by the JDK found in %JAVA_HOME%/bin/
keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app
zipalign
which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/
is a mandatory optimization step if you want to upload the apk to the Play Store.
zipalign -p 4 my.apk my-aligned.apk
Note: when using the old jarsigner
you need to zipalign AFTER signing. When using the new apksigner
method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).
You can verify the alignment with
zipalign -c 4 my-aligned.apk
Use jarsigner
which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/
and use it like so:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name
and can be verified with
jarsigner -verify -verbose my_application.apk
Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Therefore, Google implemented their own apk signer called apksigner
(duh!)
The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/
(the .jar is in the /lib
subfolder). Use it like this
apksigner sign --ks my.keystore my-app.apk --ks-key-alias alias_name
and can be verified with
apksigner verify my-app.apk
Try this, if it helps you
values = ['1', '2', '3']
with open("file.txt", "w") as output:
output.write(str(values))
For what it's worth, here's the previously provided code encapsulated within a function.
openWindowWithPost("http://www.example.com/index.php", {
p: "view.map",
coords: encodeURIComponent(coords)
});
Function definition:
function openWindowWithPost(url, data) {
var form = document.createElement("form");
form.target = "_blank";
form.method = "POST";
form.action = url;
form.style.display = "none";
for (var key in data) {
var input = document.createElement("input");
input.type = "hidden";
input.name = key;
input.value = data[key];
form.appendChild(input);
}
document.body.appendChild(form);
form.submit();
document.body.removeChild(form);
}
Although @Pascal answer is perfectly valid, from my experience I find the code below helpful to accomplish optimistic locking:
@Entity
public class MyEntity implements Serializable {
// ...
@Version
@Column(name = "optlock", columnDefinition = "integer DEFAULT 0", nullable = false)
private long version = 0L;
// ...
}
Why? Because:
@Version
is accidentally set to null
.optlock
rather than version
.First point doesn't matter if application uses only JPA for inserting data into the database, as JPA vendor will enforce 0
for @version
field at creation time. But almost always plain SQL statements are also in use (at least during unit and integration testing).
A more contemporary way of doing it on a separate thread using Tasks and Kotlin
private val mExecutor: Executor = Executors.newSingleThreadExecutor()
private fun createHttpTask(u:String): Task<String> {
return Tasks.call(mExecutor, Callable<String>{
val url = URL(u)
val conn: HttpURLConnection = url.openConnection() as HttpURLConnection
conn.requestMethod = "GET"
conn.connectTimeout = 3000
conn.readTimeout = 3000
val rc = conn.responseCode
if ( rc != HttpURLConnection.HTTP_OK) {
throw java.lang.Exception("Error: ${rc}")
}
val inp: InputStream = BufferedInputStream(conn.inputStream)
val resp: String = inp.bufferedReader(UTF_8).use{ it.readText() }
return@Callable resp
})
}
and now you can use it like below in many places:
createHttpTask("https://google.com")
.addOnSuccessListener {
Log.d("HTTP", "Response: ${it}") // 'it' is a response string here
}
.addOnFailureListener {
Log.d("HTTP", "Error: ${it.message}") // 'it' is an Exception object here
}
List membersList = Arrays.asList(membersArray);
returns immutable list, what you need to do is
new ArrayList<>(Arrays.asList(membersArray)); to make it mutable
To create a branch from another branch in your local directory you can use following command.
git checkout -b <sub-branch> branch
git checkout -b XYZ ABC
This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.
set.py:
import sys
sys.path.append("/tmp/TEST")
loop.py
import sys
import time
while True:
print sys.path
time.sleep(1)
run: python loop.py &
This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py
. Each has a different set of environment variables. Observe that the output from loop.py
does not change because set.py
does not change loop.py
's environment.
A note on importing
Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append...
.

Recently, I have seen this problem too. Below, you have my solution:
Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart
or fix it up
I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):
ssh -T [email protected]
Upon receiving a successful response, I could fetch/push to the repo with ssh.
I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.
I tried a lot of methods, and the only one which worked was UpdateCellValue:
dataGridView.Rows[rowIndex].Cells[columnIndex].Value = "New Value";
dataGridView.UpdateCellValue(columnIndex, rowIndex);
I hope to have helped. =)
For Arch Linux, it is pacman -S lib32-zlib
from multilib, not zlib
.
You could do it like this:
iterations = 10
variables = 2
output <- matrix(ncol=variables, nrow=iterations)
for(i in 1:iterations){
output[i,] <- runif(2)
}
output
and then turn it into a data.frame
output <- data.frame(output)
class(output)
what this does:
The pythonic way is to use enumerate
:
for idx,item in enumerate(list):
Just in case...
If you are using SoapUI Mock Service (as the Server), calling it from a C# WCF:
WCF --> SoapUI MockService
And in this case you are getting the same error:
The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).
Edit your Mock Response at SoapUI and add a Header to it:
In my scenario, this fix the problem.
.gitignore
is a text file comprising a list of files in your directory that git will ignore or not add/update in the repository.
.gitkeep
Since Git removes or doesn't add empty directories to a repository, .gitkeep is sort of a hack (I don't think it's officially named as a part of Git) to keep empty directories in the repository.
Just do a touch /path/to/emptydirectory/.gitkeep
to add the file, and Git will now be able to maintain this directory in the repository.
Ah yes. Welcome to Asynchronous execution.
Basically, pausing a script would cause the browser and page to become unresponsive for 3 seconds. This is horrible for web apps, and so isn't supported.
Instead, you have to think "event-based". Use setTimeout to call a function after a certain amount of time, which will continue to run the JavaScript on the page during that time.

Thinking about it in general, I would strongly consider hiding coordinate system behind well-designed abstraction. Quoting Uncle Bob and his book:
class Point(object)
def setCartesian(self, x, y)
def setPolar(self, rho, theta)
def getX(self)
def getY(self)
def getRho(self)
def setTheta(self)
With interface like that any user of Point class may choose convenient representation, no explicit conversions will be performed. All this ugly sines, cosines etc. will be hidden in one place. Point class. Only place where you should care which representation is used in computer memory.
To convert a URL to a Blob for FileReader.readAsDataURL() do this:
var request = new XMLHttpRequest();
request.open('GET', MY_URL, true);
request.responseType = 'blob';
request.onload = function() {
var reader = new FileReader();
reader.readAsDataURL(request.response);
reader.onload = function(e){
console.log('DataURL:', e.target.result);
};
};
request.send();
@JohnHartsock: You can also write type="password". It's acceptable in aspx.
<asp:TextBox ID="txtBox" type="password" runat="server"/>
warning! this does not work with links.
var variable = 'variable', another = 'another';
['I would', 'like to'].join(' ') + ' a js ' + variable + ' together with ' + another + ' to create ' + [another, ...[variable].concat('name')].join(' ').concat('...');
Add double quote
$nameRegex = "chalmw-dm*"
-like "$nameregex"
or -like "'$nameregex'"
Functionality is supposed to be broken in jQuery 1.5.
Since jQuery 1.5.1 you should use xhrFields param.
$.ajaxSetup({
type: "POST",
data: {},
dataType: 'json',
xhrFields: {
withCredentials: true
},
crossDomain: true
});

I think the easiest is to simply open the file in write mode and then close it. For example, if your file myfile.dat
contains:
"This is the original content"
Then you can simply write:
f = open('myfile.dat', 'w')
f.close()
This would erase all the content. Then you can write the new content to the file:
f = open('myfile.dat', 'w')
f.write('This is the new content!')
f.close()
Just put yourRelativeLayout
inside ScrollView
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
------- here RelativeLayout ------
</ScrollView>
The reason for this is that I am printing these out to a document and I want to use the key name and the value in doing this
Based on the above requirement this is what I would suggest:
keys = mydictionary.keys()
keys.sort()
for each in keys:
print "%s: %s" % (each, mydictionary.get(each))
A variable is final or effectively final when it's initialized once and it's never mutated in its owner class. And we can't initialize it in loops or inner classes.
Final:
final int number;
number = 23;
Effectively Final:
int number;
number = 34;
Note: Final and Effective Final are similar(Their value don't change after assignment) but just that effective Final variables are not declared with Keyword
final
.
Well According to a comment on the shuf answer he shuffed 78 000 000 000 lines in under a minute.
Challenge accepted...
EDIT: I beat my own record
$ time ./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null
./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null 0.02s user 0.01s system 80% cpu 0.047 total
The reason it is so fast, well I don't read the whole file and just move the file pointer 10 times and print the line after the pointer.
First I needed a file of 78.000.000.000 lines:
seq 1 78 | xargs -n 1 -P 16 -I% seq 1 1000 | xargs -n 1 -P 16 -I% echo "" > lines_78000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000.txt > lines_78000000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000000.txt > lines_78000000000.txt
This gives me a a file with 78 Billion newlines ;-)
Now for the shuf part:
$ time shuf -n 10 lines_78000000000.txt
shuf -n 10 lines_78000000000.txt 2171.20s user 22.17s system 99% cpu 36:35.80 total
The bottleneck was CPU and not using multiple threads, it pinned 1 core at 100% the other 15 were not used.
Python is what I regularly use so that's what I'll use to make this faster:
#!/bin/python3
import random
f = open("lines_78000000000.txt", "rt")
count = 0
while 1:
buffer = f.read(65536)
if not buffer: break
count += buffer.count('\n')
for i in range(10):
f.readline(random.randint(1, count))
This got me just under a minute:
$ time ./shuf.py
./shuf.py 42.57s user 16.19s system 98% cpu 59.752 total
I did this on a Lenovo X1 extreme 2nd gen with the i9 and Samsung NVMe which gives me plenty read and write speed.
I know it can get faster but I'll leave some room to give others a try.

Let alone enabling the network adapter under Device Manager may not help. The following helped me resolved the issue.
I tried Disabling and Enabling the Wifi Adapter (i.e. the actual Wifi device adapter not the virtual adapters) in Control Panel -> Network and Internet -> Network Connections altogether worked for me. The same can be done from the Device Manager too. This surely resets the adapter settings and for the Wifi Adapter and the Virtual Miniport adapters.
However, please make sure that the mode is set to allow
as in the below example before you run the start command.
netsh wlan set hostednetwork mode=allow ssid=ssidOfUrChoice key=keyOfUrChoice
and after that run the command netsh wlan start hostednetwork
.
Also once the usage is over with the Miniport adapter connection, it is a good practice to stop it using the following command.
netsh wlan stop hostednetwork
Hope it helps.
The Android build tools provide a debug signing mode that makes it easier for you to develop and debug your application, while still meeting the Android system requirement for signing your APK. When using debug mode to build your app, the SDK tools invoke Keytool to automatically create a debug keystore and key. This debug key is then used to automatically sign the APK, so you do not need to sign the package with your own key.
The SDK tools create the debug keystore/key with predetermined names/passwords:
Keystore name: "debug.keystore"
Keystore password: "android"
Key alias: "androiddebugkey"
Key password: "android"
CN: "CN=Android Debug,O=Android,C=US"
If necessary, you can change the location/name of the debug keystore/key or supply a custom debug keystore/key to use. However, any custom debug keystore/key must use the same keystore/key names and passwords as the default debug key (as described above). (To do so in Eclipse/ADT, go to Windows > Preferences > Android > Build.)
Caution: You cannot release your application to the public when signed with the debug certificate.

InetAddress.getByName also works for ip address.
From the JavaDoc
The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.
If you use Microsoft Azure Storage Explorer, there is a "New Folder" button that allows you to create a folder in a container. This is actually a virtual folder:

If you do not jQuery will guess the requested data type (check: http://api.jquery.com/jQuery.ajax/). My guess is that in your case response
was a String
rather than a DOMObject
. Obviously DOM methods won't work on a String.
You could test that with console.log("type of response: " + typeof response)
(or alert("type of response:" + typeof response)
, in case you don't run Firebug)
New Table...
Use D. See docs for further information.
To format by code Date in Excel cells try this:
Excel.Range rg = (Excel.Range)xlWorkSheet.Cells[numberRow, numberColumn];
rg.NumberFormat = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern;
After this you can set the DateTime value to specific cell
xlWorkSheet.Cells[numberRow, numberColumn] = myDate;
If you want to set entire column try this: Excel.Range rg = (Excel.Range)xlWorkSheet.Cells[numberRow, numberColumn];
rg.EntireColumn.NumberFormat =
CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern;
These two together worked for me:
android:scrollbarFadeDuration="0"
android:scrollbarAlwaysDrawVerticalTrack="true"

If it's just a matter of easy reading, you could always define your own function :
is.not.null <- function(x) !is.null(x)
So you can use it all along your program.
is.not.null(3)
is.not.null(NULL)
Below code handles upper and lower cases as well and leaves other character as it is.

int k = Integer.parseInt(in.nextLine());
k = k % 26;
System.out.println(encrypt(str, length, k));
in.close();
}
private static String encrypt(String str, int length, int shift)
{
StringBuilder strBuilder = new StringBuilder();
char c;
for (int i = 0; i < length; i++)
{
c = str.charAt(i);
// if c is letter ONLY then shift them, else directly add it
if (Character.isLetter(c))
{
c = (char) (str.charAt(i) + shift);
// System.out.println(c);
// checking case or range check is important, just if (c > 'z'

c = (char) (str.charAt(i) - (26 - shift));
}
strBuilder.append(c);
}
return strBuilder.toString();
}
}

SQL Server 2008 And Up
Just filter a unique index:
CREATE UNIQUE NONCLUSTERED INDEX UQ_Party_SamAccountName
ON dbo.Party(SamAccountName)
WHERE SamAccountName IS NOT NULL;
In Lower Versions, A Materialized View Is Still Not Required
For SQL Server 2005 and earlier, you can do it without a view. I just added a unique constraint like you're asking for to one of my tables. Given that I want uniqueness in column SamAccountName
, but I want to allow multiple NULLs, I used a materialized column rather than a materialized view:
ALTER TABLE dbo.Party ADD SamAccountNameUnique
AS (Coalesce(SamAccountName, Convert(varchar(11), PartyID)))
ALTER TABLE dbo.Party ADD CONSTRAINT UQ_Party_SamAccountName
UNIQUE (SamAccountNameUnique)
You simply have to put something in the computed column that will be guaranteed unique across the whole table when the actual desired unique column is NULL. In this case, PartyID
is an identity column and being numeric will never match any SamAccountName
, so it worked for me. You can try your own method—be sure you understand the domain of your data so that there is no possibility of intersection with real data. That could be as simple as prepending a differentiator character like this:
Coalesce('n' + SamAccountName, 'p' + Convert(varchar(11), PartyID))
Even if PartyID
became non-numeric someday and could coincide with a SamAccountName
, now it won't matter.
Note that the presence of an index including the computed column implicitly causes each expression result to be saved to disk with the other data in the table, which DOES take additional disk space.
Note that if you don't want an index, you can still save CPU by making the expression be precalculated to disk by adding the keyword PERSISTED
to the end of the column expression definition.
In SQL Server 2008 and up, definitely use the filtered solution instead if you possibly can!
Controversy
Please note that some database professionals will see this as a case of "surrogate NULLs", which definitely have problems (mostly due to issues around trying to determine when something is a real value or a surrogate value for missing data; there can also be issues with the number of non-NULL surrogate values multiplying like crazy).
However, I believe this case is different. The computed column I'm adding will never be used to determine anything. It has no meaning of itself, and encodes no information that isn't already found separately in other, properly defined columns. It should never be selected or used.
So, my story is that this is not a surrogate NULL, and I'm sticking to it! Since we don't actually want the non-NULL value for any purpose other than to trick the UNIQUE
index to ignore NULLs, our use case has none of the problems that arise with normal surrogate NULL creation.
All that said, I have no problem with using an indexed view instead—but it brings some issues with it such as the requirement of using SCHEMABINDING
. Have fun adding a new column to your base table (you'll at minimum have to drop the index, and then drop the view or alter the view to not be schema bound). See the full (long) list of requirements for creating an indexed view in SQL Server (2005) (also later versions), (2000).
Update
If your column is numeric, there may be the challenge of ensuring that the unique constraint using Coalesce
does not result in collisions. In that case, there are some options. One might be to use a negative number, to put the "surrogate NULLs" only in the negative range, and the "real values" only in the positive range. Alternately, the following pattern could be used. In table Issue
(where IssueID
is the PRIMARY KEY
), there may or may not be a TicketID
, but if there is one, it must be unique.
ALTER TABLE dbo.Issue ADD TicketUnique
AS (CASE WHEN TicketID IS NULL THEN IssueID END);
ALTER TABLE dbo.Issue ADD CONSTRAINT UQ_Issue_Ticket_AllowNull
UNIQUE (TicketID, TicketUnique);
If IssueID 1 has ticket 123, the UNIQUE
constraint will be on values (123, NULL). If IssueID 2 has no ticket, it will be on (NULL, 2). Some thought will show that this constraint cannot be duplicated for any row in the table, and still allows multiple NULLs.
Just a tip: Remember to put the code detection on document.ready, otherwise it might not work. That was my case.
You can not always count on privacy of the full URL either. For instance, as is sometimes the case on enterprise networks, supplied devices like your company PC are configured with an extra "trusted" root certificate so that your browser can quietly trust a proxy (man-in-the-middle) inspection of https traffic. This means that the full URL is exposed for inspection. This is usually saved to a log.
Furthermore, your passwords are also exposed and probably logged and this is another reason to use one time passwords or to change your passwords frequently.
Finally, the request and response content is also exposed if not otherwise encrypted.
One example of the inspection setup is described by Checkpoint here. An old style "internet café" using supplied PC's may also be set up this way.
Anyone using JavaScript (as opposed to JQuery), might like to try this solution, where 'models' is the ID of the select field containing the list :-
var DDlist = document.getElementById("models");
while(DDlist.length>0){DDlist.remove(0);}
I think they are slightly different concepts, but often they are applied together. Encapsulation is a technique for hiding implementation details from the caller, whereas abstraction is more a design philosophy involving creating objects that are analogous to familiar objects/processes, to aid understanding. Encapsulation is just one of many techniques that can be used to create an abstraction.
For example, take "windows". They are not really windows in the traditional sense, they are just graphical squares on the screen. But it's useful to think of them as windows. That's an abstraction.
If the "windows API" hides the details of how the text or graphics is physically rendered within the boundaries of a window, that's encapsulation.
For PHP 8+ we can omit the variable name for a caught exception.
As of PHP 8.0.0, the variable name for a caught exception is optional. If not specified, the catch block will still execute but will not have access to the thrown object.
And thus we can do it like this:
try {
throw new Exception("An error");
}
catch (Exception) {}

My case is not mentioned here:
I have to run the web project on a fake domain (settup on IIS and /hosts/etc) because of the callbacks from a third party site.
I was seeing two w3wp processes in the process list of VS:
w3wp.exe User Name: IIS APPPOOL\Default app pool
w3wp.exe User Name: IIS APPPOOL.svc
I had to to manually attach to second one to be able to debug.
So I realised the app pool of my Fake domain in iis is not set to "Default app pool"

As soon as I changed the domain's app pool to the "Default app pool" visual studio started to debug the web app.

In SQL Server 2008 and newer you can cast the DateTime
to a Date
, which removes the time element.
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= (cast(GETDATE()-6 as date))
In SQL Server 2005 and below you can use:
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= DateAdd(Day, Datediff(Day,0, GetDate() -6), 0)
Jonty, I'm struggling with this too.
I think there's a clue in here:
otool -L /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/libruby.1.dylib (compatibility version 1.8.0, current version 1.8.7)
libmysqlclient.16.dylib (compatibility version 16.0.0, current version 16.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.1)
Notice the path to the dylib is, uh, rather short?
I'm trying to figure out where the gem install instructions are leaving off the dylib path, but it's slow going as I have never built a gem myself.
I'll post more if I find more!
Create class with namespace name might resovle your issue

There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

On secure networks setting your network to bridge might not work. Administrators could only allow one mac address per port or even worse block the port should the switches detect multiple macs on one port.
The best solution in my opinion is to set up additional network interfaces to handle additional services you would like to run on your machines. So I have a bridge interface to allow for bridging when I take my laptop home and can SSH into it from other devices on my network as well as a host only adapter when I would like to SSH into my VM from my laptop when I am connected to the eduroam wifi network on campus.
Here is what I look at everytime I am writing a new crontab entry:
To start editing from terminal -type:
zee$ crontab -e
what you will add to crontab file:
0 22 * * 0 some-user /opt/somescript/to/run.sh
What it means:
[
+ user => 'some-user',
+ minute => ‘0’, <<= on top of the hour.
+ hour => '22', <<= at 10 PM. Military time.
+ monthday => '*', <<= Every day of the month*
+ month => '*', <<= Every month*
+ weekday => ‘0’, <<= Everyday (0 thru 6) = sunday thru saturday
]
Also, check what shell your machine is running and name the the file accordingly OR it wont execute.
Check the shell with either echo $SHELL
or echo $0
It can be "Bourne shell (sh)
, Bourne again shell (bash)
,Korn shell (ksh)
..etc"
This code works too:
$("input[reference=12345].myclass").css('border', '#000 solid 1px');
Use the timeIntervalSinceDate
method
NSTimeInterval secondsElapsed = [secondDate timeIntervalSinceDate:firstDate];
NSTimeInterval
is just a double
, define in NSDate
like this:
typedef double NSTimeInterval;
In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:
using (var reader = new PdfReader(@"C:\Input.pdf"))
{
using (var fileStream = new FileStream(@"C:\Output.pdf", FileMode.Create, FileAccess.Write))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 12);
var multiLineString = "Hello,\r\nWorld!".Split('\n');
foreach (var line in multiLineString)
{
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
}
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
writer.Close();
}
}
As @markE mention in his answer
the alternative is to untranslate & unrotate after drawing
It is much faster than context save and restore.
Here is an example
// translate and rotate
this.context.translate(x,y);
this.context.rotate(radians);
this.context.translate(-x,-y);
this.context.drawImage(...);
// untranslate and unrotate
this.context.translate(x, y);
this.context.rotate(-radians);
this.context.translate(-x,-y);
I think this will be helpful.
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
applicationVariants.all { variant ->
variant.outputs.each { output ->
project.ext { appName = 'MyAppName' }
def formattedDate = new Date().format('yyyyMMddHHmmss')
def newName = output.outputFile.name
newName = newName.replace("app-", "$project.ext.appName-")
newName = newName.replace("-release", "-release" + formattedDate)
output.outputFile = new File(output.outputFile.parent, newName)
}
}
}
}
productFlavors {
flavor1 {
}
flavor2 {
proguardFile 'flavor2-rules.pro'
}
}
As mentioned you might have a variable named round (of type int
) in your code and removing that should get rid of the error. For Jupyter notebooks however, simply clearing a cell or deleting it might not take the variable out of scope. In such a case, you can restart your notebook to start afresh after deleting the variable.
A backslash needs to be escaped with another backslash.
print('\\')
You can use SELECT @@IDENTITY as well
Style the td
and th
instead
td, th {
border: 1px solid black;
}
And also to make it so there is no spacing between cells use:
table {
border-collapse: collapse;
}
(also note, you have border-style: none;
which should be border-style: solid;
)
See an example here: http://jsfiddle.net/KbjNr/
var myVar = $("#start").find('.myClass').first().val();
It's quite unpractical to make multiple select with size 1. think about it. I made a fiddle here: https://jsfiddle.net/wqd0yd5m/2/

<option>456</option>
<option>789</option>
</select>

Another reason could be; you are accessing your application through nginx using proxy but you did not add gunicorn.sock
file for proxy with gunicorn.
You need to add a proxy file path in nginx configuration.
location / {
include proxy_params;
proxy_pass http://unix:/home/username/myproject/gunicorn.sock;
}
Here is a nice tutorial with step by step implementation of this
Note: if you did not created anyname.sock
file you have to create if first, either use above or any other method or tutorial to create it.
So I just solved my own "SMTP connection failure" error and I wanted to post the solution just in case it helps anyone else.
I used the EXACT code given in the PHPMailer example gmail.phps file. It worked simply while I was using MAMP and then I got the SMTP connection error once I moved it on to my personal server.
All of the Stack Overflow answers I read, and all of the troubleshooting documentation from PHPMailer said that it wasn't an issue with PHPMailer. That it was a settings issue on the server side. I tried different ports (587, 465, 25), I tried 'SSL' and 'TLS' encryption. I checked that openssl was enabled in my php.ini file. I checked that there wasn't a firewall issue. Everything checked out, and still nothing.
The solution was that I had to remove this line:
$mail->isSMTP();
Now it all works. I don't know why, but it works. The rest of my code is copied and pasted from the PHPMailer example file.
You need to apply the following CSS property to the container block (div):
overflow-wrap: break-word;
According to the specifications (source CSS | MDN):
The
overflow-wrap
CSS property specifies whether or not the browser should insert line breaks within words to prevent text from overflowing its content box.
With the value set to break-word
To prevent overflow, normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.
Worth mentioning...
The property was originally a nonstandard and unprefixed Microsoft extension called
word-wrap
, and was implemented by most browsers with the same name. It has since been renamed tooverflow-wrap
, withword-wrap
being an alias.
If you care about legacy browsers support it's worth specifying both:
word-wrap : break-word;
overflow-wrap: break-word;
Ex. IE9 does not recognize overflow-wrap
but works fine with word-wrap
To expand Konamiman's solution (including all relevant null checks), this is what I've been doing:
if (node.Attributes != null)
{
var nameAttribute = node.Attributes["Name"];
if (nameAttribute != null)
return nameAttribute.Value;
throw new InvalidOperationException("Node 'Name' not found.");
}
The headers you are trying to set are response headers. They have to be provided, in the response, by the server you are making the request to.
They have no place being set on the client. It would be pointless having a means to grant permissions if they could be granted by the site that wanted permission instead of the site that owned the data.
Remove column constraint: not null
to null
ALTER TABLE test ALTER COLUMN column_01 DROP NOT NULL;
Another example:
Suppose I created an immutable Rectangle class like this:
class Rectangle {
public:
Rectangle(int width, int height) : width_(width), height_(height) {}
int width() const { return width_; }
int height() const { return height_; }
private:
int width_;
int height_;
}
Now it's obvious that I've encapsulated width and height (access is somehow restricted), but I've not abstracted anything (okay, maybe I've ignored where the rectangle is located in the coordinates space, but this is a flaw of the example).
Good abstraction usually implies good encapsulation.
An example of good abstraction is a generic database connection class. Its public interface is database-agnostic, and is very simple, yet allows me to do what I want with the connection. And you see? There's also encapsulation there, because the class must have all the low-level handles and calls inside.
For users of GitHub, this worked for me:
git reset --hard <full_hash_of_commit_to_reset_to>
git push --force
This will "correct" the branch history on your local machine and the GitHub server, but anyone who has sync'ed this branch with the server since the bad commit will have the history on their local machine. If they have permission to push to the branch directly then these commits will show right back up when they sync.
All everyone else needs to do is the git reset
command from above to "correct" the branch on their local machine. Of course they would need to be wary of any local commits made to this branch after the target hash. Cherry pick/backup and reapply those as necessary, but if you are in a protected branch then the number of people who can commit directly to it is likely limited.
Using ps -aux reveals current processes, all of which are listed in /proc/ as /proc/(pid)/, by calling cat /proc/(pid)/fd/0 it prints anything that is found in the standard output of that process I think. So perhaps,
/proc/(pid)/fd/0 - Standard Output File
/proc/(pid)/fd/1 - Standard Input File
/proc/(pid)/fd/2 - Standard Error File
for example
But only worked this well for /bin/bash other processes generally had nothing in 0 but many had errors written in 2
?? To state the answer differently ??
In Xaml verify that there are no Missing Parent Nodes or incorrect nodes in the defined areas.
For example
There is no proper parent for the ItemsPanelTemplate
child node below:
<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
<ItemsPanelTemplate>
<UniformGrid Rows="1" />
</ItemsPanelTemplate>
...
</ItemsControl>
<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
<ItemsControl.ItemsPanel> <!-- I am the missing parent! -->
<ItemsPanelTemplate>
<UniformGrid Rows="1" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
...
</ItemsControl>
There is a proper parent node of <ItemsControl.ItemsPanel>
provided^^^.
If you want to maintain a sorted list which you will frequently modify (i.e. a structure which, in addition to being sorted, allows duplicates and whose elements can be efficiently referenced by index), then use an ArrayList but when you need to insert an element, always use Collections.binarySearch() to determine the index at which you add a given element. The latter method tells you the index you need to insert at to keep your list in sorted order.
You do not need to use substring at all since your format
doesn't hold that info.
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";
Date fechaNueva = format.parse(fechaStr);
System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29
