Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:
Error in
contrasts<-
(*tmp*
, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels
So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.
I found that pathlib module also supports this.
from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')
coalesce
is supported in both Oracle and SQL Server and serves essentially the same function as nvl
and isnull
. (There are some important differences, coalesce
can take an arbitrary number of arguments, and returns the first non-null one. The return type for isnull
matches the type of the first argument, that is not true for coalesce
, at least on SQL Server.)
You can pass variables using this...
$status =1;
$info = JOBS::where(function($query) use ($status){
$query->where('status',$status);
})->get();
print_r($info);
When having to fetch multiple collections, you need to:
Hibernate.initialize
for the remaining collections.So, in your case, you need a first JPQL query like this one:
MyEntity entity = session.createQuery("select e from MyEntity e join fetch e.addreses where e.id
= :id", MyEntity.class)
.setParameter("id", entityId)
.getSingleResult();
Hibernate.initialize(entity.persons);
This way, you can achieve your goal with 2 SQL queries and avoid a Cartesian Product.
For windows - just go to Mongodb folder (ex : C:\ProgramFiles\MongoDB\Server\3.4\bin) and open cmd in the folder and type "mongod.exe --dbpath c:\data\db"
if c:\data\db folder doesn't exist then create it by yourself and run above command again.
All should work fine by now.))
You can return json in PHP this way:
header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;
Since id is an attribute don't create an id element, just do this:
myPara.setAttribute("id", "id_you_like");
A standard approach/workaround/solution is to add a class
object to the constructor(s), like:
public class Foo<T> {
private Class<T> type;
public Foo(Class<T> type) {
this.type = type;
}
public Class<T> getType() {
return type;
}
public T newInstance() {
return type.newInstance();
}
}
I found this to be a more elegant solution, without flex:
.wrapper {
overflow: hidden;
}
.wrapper img {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
/* height: 100%; */ /* optional */
}
You can try xml2js. It's a simple XML to JavaScript object converter. It gets your XML converted to a JS object so that you can access its content with ease.
Here are some other options:
I have used xml2js
and it has worked fine for me. The rest you might have to try out for yourself.
If you want to refer one host define under /etc/ansible/host in a task or role, the bellow link might help:
https://www.middlewareinventory.com/blog/ansible-get-ip-address/
A possible solution is to think about it backwards: Accept a float as input and reject the input if the float is not an integer:
int n;
float f;
printf("Please enter an integer: ");
while(scanf("%f",&f)!=1 || (int)f != f)
{
...
}
n = f;
Though this does allow the user to enter something like 12.0, or 12e0, etc.
I spent days writing my own custom tool to parallelize the copies required for this, but then I ran across documentation on how to get the AWS S3 CLI sync command to synchronize buckets with massive parallelization. The following commands will tell the AWS CLI to use 1,000 threads to execute jobs (each a small file or one part of a multipart copy) and look ahead 100,000 jobs:
aws configure set default.s3.max_concurrent_requests 1000
aws configure set default.s3.max_queue_size 100000
After running these, you can use the simple sync command as follows:
aws s3 sync s3://source-bucket/source-path s3://destination-bucket/destination-path
On an m4.xlarge machine (in AWS--4 cores, 16GB RAM), for my case (3-50GB files) the sync/copy speed went from about 9.5MiB/s to 700+MiB/s, a speed increase of 70x over the default configuration.
Update: Note that S3CMD has been updated over the years and these changes are now only effective when you're working with lots of small files. Also note that S3CMD on Windows (only on Windows) is seriously limited in overall throughput and can only achieve about 3Gbps per process no matter what instance size or settings you use. Other systems like S5CMD have the same problem. I've spoken to the S3 team about this and they're looking into it.
When rejecting you should pass an rejection error, then wrap step error handlers in a function that checks whether the rejection should be processed or "rethrown" until the end of the chain :
// function mocking steps
function step(i) {
i++;
console.log('step', i);
return q.resolve(i);
}
// function mocking a failing step
function failingStep(i) {
i++;
console.log('step '+ i + ' (will fail)');
var e = new Error('Failed on step ' + i);
e.step = i;
return q.reject(e);
}
// error handler
function handleError(e){
if (error.breakChain) {
// handleError has already been called on this error
// (see code bellow)
log('errorHandler: skip handling');
return q.reject(error);
}
// firs time this error is past to the handler
console.error('errorHandler: caught error ' + error.message);
// process the error
// ...
//
error.breakChain = true;
return q.reject(error);
}
// run the steps, will fail on step 4
// and not run step 5 and 6
// note that handleError of step 5 will be called
// but since we use that error.breakChain boolean
// no processing will happen and the error will
// continue through the rejection path until done(,)
step(0) // 1
.catch(handleError)
.then(step) // 2
.catch(handleError)
.then(step) // 3
.catch(handleError)
.then(failingStep) // 4 fail
.catch(handleError)
.then(step) // 5
.catch(handleError)
.then(step) // 6
.catch(handleError)
.done(function(){
log('success arguments', arguments);
}, function (error) {
log('Done, chain broke at step ' + error.step);
});
What you'd see on the console :
step 1
step 2
step 3
step 4 (will fail)
errorHandler: caught error 'Failed on step 4'
errorHandler: skip handling
errorHandler: skip handling
Done, chain broke at step 4
Here is some working code https://jsfiddle.net/8hzg5s7m/3/
If you have specific handling for each step, your wrapper could be something like:
/*
* simple wrapper to check if rejection
* has already been handled
* @param function real error handler
*/
function createHandler(realHandler) {
return function(error) {
if (error.breakChain) {
return q.reject(error);
}
realHandler(error);
error.breakChain = true;
return q.reject(error);
}
}
then your chain
step1()
.catch(createHandler(handleError1Fn))
.then(step2)
.catch(createHandler(handleError2Fn))
.then(step3)
.catch(createHandler(handleError3Fn))
.done(function(){
log('success');
}, function (error) {
log('Done, chain broke at step ' + error.step);
});
There is an open issue in Mockito's GitHub about this exact problem.
I have found a simple workaround that does not force you to use annotations in your tests:
import org.mockito.ArgumentCaptor;
import org.mockito.Captor;
import org.mockito.MockitoAnnotations;
public final class MockitoCaptorExtensions {
public static <T> ArgumentCaptor<T> captorFor(final CaptorTypeReference<T> argumentTypeReference) {
return new CaptorContainer<T>().captor;
}
public static <T> ArgumentCaptor<T> captorFor(final Class<T> argumentClass) {
return ArgumentCaptor.forClass(argumentClass);
}
public interface CaptorTypeReference<T> {
static <T> CaptorTypeReference<T> genericType() {
return new CaptorTypeReference<T>() {
};
}
default T nullOfGenericType() {
return null;
}
}
private static final class CaptorContainer<T> {
@Captor
private ArgumentCaptor<T> captor;
private CaptorContainer() {
MockitoAnnotations.initMocks(this);
}
}
}
What happens here is that we create a new class with the @Captor
annotation and inject the captor into it. Then we just extract the captor and return it from our static method.
In your test you can use it like so:
ArgumentCaptor<Supplier<Set<List<Object>>>> fancyCaptor = captorFor(genericType());
Or with syntax that resembles Jackson's TypeReference
:
ArgumentCaptor<Supplier<Set<List<Object>>>> fancyCaptor = captorFor(
new CaptorTypeReference<Supplier<Set<List<Object>>>>() {
}
);
It works, because Mockito doesn't actually need any type information (unlike serializers, for example).
you can use
<meta http-equiv="refresh" content="10" >
just add it after the head tags
where 10 is the time your page will refresh itself
"What is it?" and "What does it do?" has been explained above.
I will give a example of "when it should be used".
For example, we have a class with lots of resource like big array in it.
class ResHeavy{ // ResHeavy means heavy resource
public:
ResHeavy(int len=10):_upInt(new int[len]),_len(len){
cout<<"default ctor"<<endl;
}
ResHeavy(const ResHeavy& rhs):_upInt(new int[rhs._len]),_len(rhs._len){
cout<<"copy ctor"<<endl;
}
ResHeavy& operator=(const ResHeavy& rhs){
_upInt.reset(new int[rhs._len]);
_len = rhs._len;
cout<<"operator= ctor"<<endl;
}
ResHeavy(ResHeavy&& rhs){
_upInt = std::move(rhs._upInt);
_len = rhs._len;
rhs._len = 0;
cout<<"move ctor"<<endl;
}
// check array valid
bool is_up_valid(){
return _upInt != nullptr;
}
private:
std::unique_ptr<int[]> _upInt; // heavy array resource
int _len; // length of int array
};
Test code:
void test_std_move2(){
ResHeavy rh; // only one int[]
// operator rh
// after some operator of rh, it becomes no-use
// transform it to other object
ResHeavy rh2 = std::move(rh); // rh becomes invalid
// show rh, rh2 it valid
if(rh.is_up_valid())
cout<<"rh valid"<<endl;
else
cout<<"rh invalid"<<endl;
if(rh2.is_up_valid())
cout<<"rh2 valid"<<endl;
else
cout<<"rh2 invalid"<<endl;
// new ResHeavy object, created by copy ctor
ResHeavy rh3(rh2); // two copy of int[]
if(rh3.is_up_valid())
cout<<"rh3 valid"<<endl;
else
cout<<"rh3 invalid"<<endl;
}
output as below:
default ctor
move ctor
rh invalid
rh2 valid
copy ctor
rh3 valid
We can see that std::move
with move constructor
makes transform resource easily.
Where else is std::move
useful?
std::move
can also be useful when sorting an array of elements. Many sorting algorithms (such as selection sort and bubble sort) work by swapping pairs of elements. Previously, we’ve had to resort to copy-semantics to do the swapping. Now we can use move semantics, which is more efficient.
It can also be useful if we want to move the contents managed by one smart pointer to another.

Does the user that you are using to connect to the database (user A
in this example) have SELECT
access on the objects in the PCT
schema? Assuming that A
does not have this access, you would get the "table or view does not exist" error.
Most likely, you need your DBA to grant user A
access to whatever tables in the PCT
schema that you need. Something like
GRANT SELECT ON pct.pi_int
TO a;
Once that is done, you should be able to refer to the objects in the PCT
schema using the syntax pct.pi_int
as you demonstrated initially in your question. The bracket syntax approach will not work.
Here's another way to do it :) The concept is to create a clip-path polygon with the wave as one side.
This approach is fairly flexible. You can change the position (left, right, top or bottom) in which the wave appears, change the wave function to any function(t) which maps to [0,1]). The polygon can also be used for shape-outside, which lets text flow around the wave when in 'left' or 'right' orientation.
At the end, an example you can uncomment which demonstrates animating the wave.

There are two attributes, namely readonly
and disabled
, that can make a semi-read-only input. But there is a tiny difference between them.
<input type="text" readonly />
<input type="text" disabled />
readonly
attribute makes your input text disabled, and users are not able to change it anymore.disabled
attribute make your input-text disabled(unchangeable) but also cannot it be submitted.jQuery approach (1):
$("#inputID").prop("readonly", true);
$("#inputID").prop("disabled", true);
jQuery approach (2):
$("#inputID").attr("readonly","readonly");
$("#inputID").attr("disabled", "disabled");
JavaScript approach:
document.getElementById("inputID").readOnly = true;
document.getElementById("inputID").disabled = true;
PS disabled
and readonly
are standard html attributes. prop
introduced with jQuery 1.6
.
Starting with a context, the root view of the associated activity can be had by
View rootView = ((Activity)_context).Window.DecorView.FindViewById(Android.Resource.Id.Content);
In Raw Android it'd look something like:
View rootView = ((Activity)mContext).getWindow().getDecorView().findViewById(android.R.id.content)
Then simply call the findViewById on this
View v = rootView.findViewById(R.id.your_view_id);

First navigate to your Java/jre/bin folder in cmd cd c:\Program Files (x86)\Java\jre7\bin
Then use : [change debug.keystore path to the correct location on your system] install openssl (for windows 32 or 64 as per your needs at c:\openssl )
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\vibhor\.android\debug.keystore" | "c:\openssl\bin\openssl.exe" sha1 -binary | "c:\openssl\bin\openssl.exe" base64

It's just about the remainders. Let me show you how
10 % 5=0
9 % 5=4 (because the remainder of 9 when divided by 5 is 4)
8 % 5=3
7 % 5=2
6 % 5=1
5 % 5=0 (because it is fully divisible by 5)
Now we should remember one thing, mod means remainder so
4 % 5=4
but why 4? because 5 X 0 = 0 so 0 is the nearest multiple which is less than 4 hence 4-0=4

The important point: for tags used for ng-repeat-start
and ng-repeat-end
set ng-if="0"
, to let not be inserted in the page. In this way the inner content will be handled exactly as it is in knockoutjs (using commands in <!--...-->
), and there will be no garbage.
SQL Server:
select * from table
except
select top N * from table
Oracle up to 11.2:
select * from table
minus
select * from table where rownum <= N
with TableWithNum as (
select t.*, rownum as Num
from Table t
)
select * from TableWithNum where Num > N
Oracle 12.1 and later (following standard ANSI SQL)
select *
from table
order by some_column
offset x rows
fetch first y rows only
They may meet your needs more or less.
There is no direct way to do what you want by SQL. However, it is not a design flaw, in my opinion.
SQL is not supposed to be used like this.
In relational databases, a table represents a relation, which is a set by definition. A set contains unordered elements.
Also, don't rely on the physical order of the records. The row order is not guaranteed by the RDBMS.
If the ordering of the records is important, you'd better add a column such as `Num' to the table, and use the following query. This is more natural.
select *
from Table
where Num > N
order by Num
You may also indicate the path to the gemfile in the same command e.g.
BUNDLE_GEMFILE="MyProject/Gemfile.ios" bundle install
Looking at Biju's answer I found a working solution.
I created an extra context-file test-context.xml
:
<context:property-placeholder location="classpath:config/spring-test.properties"/>
Containing the profile:
spring.profiles.active=localtest
And loading the test with:
@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
TestPreperationExecutionListener.class
})
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration(locations = {
"classpath:config/test-context.xml" })
public class TestContext {
@Test
public void testContext(){
}
}
This saves some work when creating multiple test-cases.
I've created this tool: https://lingtalfi.com/bootstrap4-color-generator, you simply put primary in the first field, then choose your color, and click generate.
Then copy the generated scss or css code, and paste it in a file named my-colors.scss or my-colors.css (or whatever name you want).
Once you compile the scss into css, you can include that css file AFTER the bootstrap CSS and you'll be good to go.
The whole process takes about 10 seconds if you get the gist of it, provided that the my-colors.scss file is already created and included in your head tag.
Note: this tool can be used to override bootstrap's default colors (primary, secondary, danger, ...), but you can also create custom colors if you want (blue, green, ternary, ...).
Note2: this tool was made to work with bootstrap 4 (i.e. not any subsequent version for now).
To create list of lists, you need to separate them with commas, like this
coin_args = [
["pennies", '2.5', '50.0', '.01'],
["nickles", '5.0', '40.0', '.05'],
["dimes", '2.268', '50.0', '.1'],
["quarters", '5.67', '40.0', '.25']
]
So i tried all the suggested solutions to no avail. All i did was to set run the app from the server and it displayed the error in full, this should have worked when i set customErrors mode to false but it didn't. The moment i browsed the API form the server i was able to see the problem.
This works cross-browser, provides more accessibility and comes with less markup. ditch the div. Wrap the label
label{
display: block;
height: 35px;
line-height: 35px;
border: 1px solid #000;
}
input{margin-top:15px; height:20px}
<label for="name">Name: <input type="text" id="name" /></label>
I would suggest:
function onChange(field){
field.old=field.recent;
field.recent=field.value;
//we have available old value here;
}
I found none of these suggestions works if the onClick method doesn't return immediately. The touch event is queued by Android and the next onClick is called only after the first one is finished. (Since this is done on the one UI thread this is really normal.) I needed to use the time when the the onClick function is finished + one boolean variable to mark whether the given onClick is running. Both these marker attributes are static to avoid any onClickListener to run at the same time. (If user clicks on another button) You can simple replace your OnClickListener to this class and instead of implementing the onClick method you need to implement the abstract oneClick() method.
abstract public class OneClickListener implements OnClickListener {
private static boolean started = false;
private static long lastClickEndTime = 0;
/* (non-Javadoc)
* @see android.view.View.OnClickListener#onClick(android.view.View)
*/
@Override
final public void onClick(final View v) {
if(started || SystemClock.elapsedRealtime()-lastClickEndTime <1000 ){
Log.d(OneClickListener.class.toString(), "Rejected double click, " + new Date().toString() );
return;
}
Log.d(OneClickListener.class.toString(), "One click, start: " + new Date().toString() );
try{
started = true;
oneClick(v);
}finally{
started = false;
lastClickEndTime = SystemClock.elapsedRealtime();
Log.d(OneClickListener.class.toString(), "One click, end: " + new Date().toString() );
}
}
abstract protected void oneClick(View v);
}
First we must ensure that the desired attribute is loaded, and then output it. Use this:
$product = Mage::getModel('catalog/product')->load('<product_id>', array('<attribute_code>'));
$attributeValue = $product->getResource()->getAttribute('<attribute_code>')->getFrontend()->getValue($product);
I also had this error.
My IIS Website has a Default Website with three (3) application directories below it.
I had each of my 3 application directories configured correctly to use .NET Framework v2.0 in the Application Pools.
However, the Default Website never was configured. I didn't think it was necessary since all of my apps were contained within it.
My IIS Server's default configuration is .NET Framework v4.0, so I changed that to .NET v2.0:
After I did that, I no longer received the same error message.
Now, I see this:
I hope this information helps others.
I think you are confused with the printf(String format, Object... args)
method. The first argument is the format string, which is mandatory, rest you can pass an arbitrary number of Object
s.
There is no such overload for both the print()
and println()
methods.
Try to run it at Framework64.
Example:
32 bit
C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe D:\DemoIconOverlaySln\Demo\bin\Debug\HandleOverlayWarning\AsmOverlayIconWarning.dll /codebase
64 bit
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\RegAsm.exe D:\DemoIconOverlaySln\Demo\bin\Debug\HandleOverlayWarning\AsmOverlayIconWarning.dll /codebase
Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http
argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.
So, you need to look to see whether /dvlpmnt/libPI-Http.a
is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32
option. Then you need to establish whether there is an alternative libPI-Http.a
or libPI-Http.so
file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where
argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.
To establish what is in that library, you may need to do:
mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk
The 'file
' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.
I needed to delete all rows except the first and solution posted by @strat but that resulted in uncaught exception (referencing Node in context where it does not exist). The following worked for me.
var myTable = document.getElementById("myTable");
var rowCount = myTable.rows.length;
for (var x=rowCount-1; x>0; x--) {
myTable.deleteRow(x);
}
Is it a good practice to use try-except-else in python?
The answer to this is that it is context dependent. If you do this:
d = dict()
try:
item = d['item']
except KeyError:
item = 'default'
It demonstrates that you don't know Python very well. This functionality is encapsulated in the dict.get
method:
item = d.get('item', 'default')
The try
/except
block is a much more visually cluttered and verbose way of writing what can be efficiently executing in a single line with an atomic method. There are other cases where this is true.
However, that does not mean that we should avoid all exception handling. In some cases it is preferred to avoid race conditions. Don't check if a file exists, just attempt to open it, and catch the appropriate IOError. For the sake of simplicity and readability, try to encapsulate this or factor it out as apropos.
Read the Zen of Python, understanding that there are principles that are in tension, and be wary of dogma that relies too heavily on any one of the statements in it.
If, like me, you landed here with:
Here is what worked for me, utilizing one of the above answers and expanding it:
-- up
ALTER TABLE myoldtable ADD COLUMN newcolumn TEXT;
ALTER TABLE myoldtable ADD CONSTRAINT myoldtable_oldcolumn_newcolumn_key UNIQUE (oldcolumn, newcolumn);
---
ALTER TABLE myoldtable DROP CONSTRAINT myoldtable_oldcolumn_newcolumn_key;
ALTER TABLE myoldtable DROP COLUMN newcolumn;
-- down
This can replace the MaxLength and the MinLength
[StringLength(40, MinimumLength = 10 , ErrorMessage = "Password cannot be longer than 40 characters and less than 10 characters")]
jQuery ui 1.9 is going to take care of this for you. Heres a demo of the pre:

There are in fact 3 questions in your question :
What JB King has described is correct, but it is a particular, simple version, where in fact he mapped front, middle and bacn to an MVC layer. He mapped M to the back, V to the front, and C to the middle.
For many people, it is just fine, since they come from the ugly world where even MVC was not applied, and you could have direct DB calls in a view.
However in real, complex web applications, you indeed have two or three different layers, called front, middle and back. Each of them may have an associated database and a controller.
The front-end will be visible by the end-user. It should not be confused with the front-office, which is the UI for parameters and administration of the front. The front-end will usually be some kind of CMS or e-commerce Platform (Magento, etc.)
The middle-end is not compulsory and is where the business logics is. It will be based on a PIM, a MDM tool, or some kind of custom database where you enrich your produts or your articles (for CMS). It'll also be the place where you code business functions that need to be shared between differents frontends (for instance between the PC frontend and the API-based mobile application). Sometimes, an ESB or tool like ActiveMQ will be your middle-end
The back-end will be a 3rd layer, surrouding your source database or your ERP. It may be jsut the API wrting to and reading from your ERP. It may be your supplier DB, if you are doing e-commerce. In fact, it really depends on web projects, but it is always a central repository. It'll be accessed either through a DB call, through an API, or an Hibernate layer, or a full-featured back-end application
This description means that answering the other 2 questions is not possible in this thread, as bottlenecks really depend on what your 3 ends contain : what JB King wrote remains true for simple MVC architectures
at the time the question was asked (5 years ago), maybe the MVC pattern was not yet so widely adopted. Now, there is absolutely no reason why the MVC pattern would not be followed and a view would be tied to DB calls. If you read the question "Are there cases where they MUST overlap, and frontend/backend cannot be separated?" in a broader sense, with 3 different components, then there times when the 3 layers architecture is useless of course. Think of a simple personal blog, you'll not need to pull external data or poll RabbitMQ queues.
#include <iostream>
#include <sstream>
std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;
while(std::getline(ss, token, ',')) {
std::cout << token << '\n';
}
abc
def
ghi
Within your component, you can define an array of number (ES6) as described below:
export class SampleComponent {
constructor() {
this.numbers = Array(5).fill(0).map((x,i)=>i);
}
}
See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.
You can then iterate over this array with ngFor
:
@View({
template: `
<ul>
<li *ngFor="let number of numbers">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Or shortly:
@View({
template: `
<ul>
<li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Hope it helps you, Thierry
Edit: Fixed the fill statement and template syntax.
As aix mentioned - strings in Python are immutable (you cannot change them inplace).
What you are trying to do can be done in many ways:
# Copy the string
foo = 'Hello'
bar = foo
# Create a new string by joining all characters of the old string
new_string = ''.join(c for c in oldstring)
# Slice and copy
new_string = oldstring[:]
On Debian (or Ubuntu) systems, just install libmysqlclient-dev package using:
sudo apt-get install libmysqlclient-dev
and then:
gem install mysql
It will be installed without any error.
If you are using GCP then you have to set workers per instance type.

For small changes, I have used hexedit:
http://rigaux.org/hexedit.html
Simple but fast and useful.
To get the keys:
function GetDictionaryKeysAsArray(dict: {[key: string]: string;}): string[] {
let result: string[] = [];
Object.keys(dict).map((key) =>
result.push(key),
);
return result;
}
You can take using the following method
mysqldump -d <database name> > <filename.sql> // -d : without data
Hope it will helps you
#collect
is actually an alias for #map
. That means the two methods can be used interchangeably, and effect the same behavior.
find and replace:
utf8mb4_unicode_520_ci
with
utf8_general_ci

I have created a function to make the task easier.
For 7 days after dateString: dateCalculate(dateString,"yyyy-MM-dd",7);
To get 7 days upto dateString: dateCalculate(dateString,"yyyy-MM-dd",-7);
public static String dateCalculate(String dateString, String dateFormat, int days) {
Calendar cal = Calendar.getInstance();
SimpleDateFormat s = new SimpleDateFormat(dateFormat);
try {
cal.setTime(s.parse(dateString));
} catch (ParseException e) {
e.printStackTrace();
}
cal.add(Calendar.DATE, days);
return s.format(cal.getTime());
}
In MVC IP can be obtained by the following Code
string ipAddress = Request.ServerVariables["REMOTE_ADDR"];
main()
is a static method which has two fundamental restrictions:
this()
and super()
cannot be used in static context.
class A {
int a = 40; //non static
public static void main(String args[]) {
System.out.println(a);
}
}
Output: Compile Time Error
If you're already using Apache commons, it provides a static method for this:
StringEscapeUtils.escapeJson("some string")
It converts any string into one that's properly escaped for inclusion in JSON
change the opacity of the parent element with the border and this will re organize the stacked elements. This worked miraculously for me after hours of research and failed attempts. It was as simple as adding an opacity of 0.99 to re organize this paint process of browsers. Check out http://philipwalton.com/articles/what-no-one-told-you-about-z-index/
You could do it like that:
File folder = new File("your/path");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
System.out.println("File " + listOfFiles[i].getName());
} else if (listOfFiles[i].isDirectory()) {
System.out.println("Directory " + listOfFiles[i].getName());
}
}
Do you want to only get JPEG files or all files?
Here's how I've worked it out:
tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log
FOR /F %%A IN (search.log) DO IF %%~zA EQU 0 GOTO end
start notepad.exe
:end
del search.log
The above will open Notepad if it is not already running.
Edit: Note that this won't find applications hidden from the tasklist. This will include any scheduled tasks running as a different user, as these are automatically hidden.
The biggest/largest integer that can be stored in a double without losing precision is the same as the largest possible value of a double. That is, DBL_MAX
or approximately 1.8 × 10308 (if your double is an IEEE 754 64-bit double). It's an integer. It's represented exactly. What more do you want?
Go on, ask me what the largest integer is, such that it and all smaller integers can be stored in IEEE 64-bit doubles without losing precision. An IEEE 64-bit double has 52 bits of mantissa, so I think it's 253:
Or another way of looking at it: once the bias has been taken off the exponent, and ignoring the sign bit as irrelevant to the question, the value stored by a double is a power of 2, plus a 52-bit integer multiplied by 2exponent - 52. So with exponent 52 you can store all values from 252 through to 253 - 1. Then with exponent 53, the next number you can store after 253 is 253 + 1 × 253 - 52. So loss of precision first occurs with 253 + 1.

nodejs offers vm
. It creates a V8 virtual machine that can sandbox the execution of your code in a separate context.
Taking things a step further is vm2
which hardens vm
allowing the vm to run untrusted code.

const vm = require('vm');
const x = 1;
const sandbox = { x: 2 };
vm.createContext(sandbox); // Contextify the sandbox.
const code = 'x += 40; var y = 17;';
// `x` and `y` are global variables in the sandboxed environment.
// Initially, x has the value 2 because that is the value of sandbox.x.
vm.runInContext(code, sandbox);
console.log(sandbox.x); // 42
console.log(sandbox.y); // 17
console.log(x); // 1; y is not defined.

Let's suppose you have a book, probably a novel, a thick one with lots of things to read, hence lots of words. Now, hypothetically, you brought two dictionaries, consisting of only words that are only used, at least one time in the novel. All words in that two dictionaries are stored in typical alphabetical order. In hypothetical dictionary A, words are printed only once while in hypothetical dictionary B words are printed as many numbers of times it is printed in the novel. Remember, words are sorted alphabetically in both the dictionaries. Now you got stuck at some point while reading a novel and need to find the meaning of that word from anyone of those hypothetical dictionaries. What you will do? Surely you will jump to that word in a few steps to find its meaning, rather look for the meaning of each of the words in the novel, from starting, until you reach that bugging word.
This is how the index works in SQL. Consider Dictionary A as PRIMARY INDEX, Dictionary B as KEY/SECONDARY INDEX, and your desire to get for the meaning of the word as a QUERY/SELECT STATEMENT. The index will help to fetch the data at a very fast rate. Without an index, you will have to look for the data from the starting, unnecessarily time-consuming costly task.
For more about indexes and types, look this.
Use this instead
echo $LINE | sed -e 's/12345678/$replace/g'
this works for me just simply remove the quotes
The filter option filters only the first level subkey below ansible_facts

dateValue.ToString(isoDateTimeFormat.UniversalSortableDateTimePattern)
Also try using parameters when you store the c# datetime value in the mySql database, this might help.
Here's an example code that calculates the RMSE between two polygon file formats PLY
. It uses both the ml_metrics
lib and the np.linalg.norm
:
import sys
import SimpleITK as sitk
from pyntcloud import PyntCloud as pc
import numpy as np
from ml_metrics import rmse
if len(sys.argv) < 3 or sys.argv[1] == "-h" or sys.argv[1] == "--help":
print("Usage: compute-rmse.py <input1.ply> <input2.ply>")
sys.exit(1)
def verify_rmse(a, b):
n = len(a)
return np.linalg.norm(np.array(b) - np.array(a)) / np.sqrt(n)
def compare(a, b):
m = pc.from_file(a).points
n = pc.from_file(b).points
m = [ tuple(m.x), tuple(m.y), tuple(m.z) ]; m = m[0]
n = [ tuple(n.x), tuple(n.y), tuple(n.z) ]; n = n[0]
v1, v2 = verify_rmse(m, n), rmse(m,n)
print(v1, v2)
compare(sys.argv[1], sys.argv[2])
You can use preg_replace in this case;
$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );
$res return 6 in this case.
If want also to include decimal separator or thousand separator check this example:
$res = preg_replace("/[^0-9.]/", "", "$ 123.099");
$res returns "123.099" in this case
Include period as decimal separator or thousand separator: "/[^0-9.]/"
Include coma as decimal separator or thousand separator: "/[^0-9,]/"
Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"
Instead of using a separate CTE to get the total, you can use a window function without the "partition by" clause.
If you are using:
count(*)
to get the count for a group, you can use:
sum(count(*)) over ()
to get the total count.
For example:
select Grade, 100. * count(*) / sum(count(*)) over ()
from table
group by Grade;
It tends to be faster in my experience, but I think it might internally use a temp table in some cases (I've seen "Worktable" when running with "set statistics io on").
EDIT: I'm not sure if my example query is what you are looking for, I was just illustrating how the windowing functions work.
This is a class I use to create Message Digest hashes
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class Sha1Hex {
public String makeSHA1Hash(String input)
throws NoSuchAlgorithmException, UnsupportedEncodingException
{
MessageDigest md = MessageDigest.getInstance("SHA1");
md.reset();
byte[] buffer = input.getBytes("UTF-8");
md.update(buffer);
byte[] digest = md.digest();
String hexStr = "";
for (int i = 0; i < digest.length; i++) {
hexStr += Integer.toString( ( digest[i] & 0xff ) + 0x100, 16).substring( 1 );
}
return hexStr;
}
}
I am siteConfiguration class for calling all my appSetting like this way. I share it if it will help anyone.
add the following code at the "web.config"
<configuration>
<configSections>
<!-- some stuff omitted here -->
</configSections>
<appSettings>
<add key="appKeyString" value="abc" />
<add key="appKeyInt" value="123" />
</appSettings>
</configuration>
Now you can define a class for getting all your appSetting value. like this
using System;
using System.Configuration;
namespace Configuration
{
public static class SiteConfigurationReader
{
public static String appKeyString //for string type value
{
get
{
return ConfigurationManager.AppSettings.Get("appKeyString");
}
}
public static Int32 appKeyInt //to get integer value
{
get
{
return ConfigurationManager.AppSettings.Get("appKeyInt").ToInteger(true);
}
}
// you can also get the app setting by passing the key
public static Int32 GetAppSettingsInteger(string keyName)
{
try
{
return Convert.ToInt32(ConfigurationManager.AppSettings.Get(keyName));
}
catch
{
return 0;
}
}
}
}
Now add the reference of previous class and to access a key call like bellow
string appKeyStringVal= SiteConfigurationReader.appKeyString;
int appKeyIntVal= SiteConfigurationReader.appKeyInt;
int appKeyStringByPassingKey = SiteConfigurationReader.GetAppSettingsInteger("appKeyInt");
This always works for me:

This is probably the simplest solution to this problem. Only need to set four CSS attributes (although one of them is only to make IE happy).

You can make use of the Support Library's NestedScrollView
and it's NestedScrollView.OnScrollChangeListener
interface.
https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
Alternatively if your app is targeting API 23 or above, you can make use of the following method on the ScrollView
:
View.setOnScrollChangeListener(OnScrollChangeListener listener)
Then follow the example that @Fustigador described in his answer. Note however that as @Will described, you should consider adding a small buffer in case the user or system isn't able to reach the complete bottom of the list for any reason.
Also worth noting is that the scroll change listener will sometimes be called with negative values or values greater than the view height. Presumably these values represent the 'momentum' of the scroll action. However unless handled appropriately (floor / abs) they can cause problems detecting the scroll direction when the view is scrolled to the top or bottom of the range.
Assuming you don't want to immediately decode it again like others are suggesting here, you can parse it to a string and then just strip the leading 'b
and trailing '
.
>>> x = "Hi there "
>>> x = "Hi there ".encode("utf-8")
>>> x
b"Hi there \xef\xbf\xbd"
>>> str(x)[2:-1]
"Hi there \\xef\\xbf\\xbd"
but it's not working in IE. recommend using :nth-child(2n+1) :nth-child(2n+2)
li {_x000D_
color: black;_x000D_
}_x000D_
li:nth-child(odd) {_x000D_
color: #777;_x000D_
}_x000D_
li:nth-child(even) {_x000D_
color: blue;_x000D_
}
_x000D_
<ul>_x000D_
<li>ho</li>_x000D_
<li>ho</li>_x000D_
<li>ho</li>_x000D_
<li>ho</li>_x000D_
<li>ho</li>_x000D_
</ul>
_x000D_
That doesn't set the format of the string; it sets the format of the file. Even with that header, "hello"
is a byte string, not a Unicode string. To make it Unicode, you're going to have to use u"hello"
everywhere. The header is just a hint of what format to use when reading the .py
file.
User can use this
Dim todaysdate As String = String.Format("{0:dd/MM/yyyy}", DateTime.Now)
this will format the date as required whereas user can change the string type dd/MM/yyyy or MM/dd/yyyy or yyyy/MM/dd or even can have this format to get the time from date
yyyy/MM/dd HH:mm:ss
Don't reinvent the wheel.

Apache DBCP comes with different example on how to setup a pooling javax.sql.DataSource. Here is one sample that can help you get started.
If you just need an int to a string as you suggest, I've found the easiest way is to do as below:

The correct way to use max in the having clause is by performing a self join first:
select t1.a, t1.b, t1.c
from table1 t1
join table1 t1_max
on t1.id = t1_max.id
group by t1.a, t1.b, t1.c
having t1.date = max(t1_max.date)
The following is how you would join with a subquery:
select t1.a, t1.b, t1.c
from table1 t1
where t1.date = (select max(t1_max.date)
from table1 t1_max
where t1.id = t1_max.id)
Be sure to create a single dataset before using an aggregate when dealing with a multi-table join:
select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
on t1.id = t2.id
join table2 t3
on t1.id = t3.id
select a, b, c
from #dataset d
join #dataset d_max
on d.id = d_max.id
having d.date = max(d_max.date)
group by a, b, c
Sub query version:
select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
on t1.id = t2.id
join table2 t3
on t1.id = t3.id
select a, b, c
from #dataset d
where d.date = (select max(d_max.date)
from #dataset d_max
where d.id = d_max.id)
As mentioned in Vagrant issue #3341 this was a Virtualbox bug #12879.
It affects only VirtualBox 4.3.10 and was completely fixed in 4.3.12.

I agree with Brandrew, the problem is most likely caused by some missing dlls that can't be found neither on the system path nor in the folder where the executable is. Try putting the following DLLs nearby the executable:
Alternatively, try loading the executable into Dependency Walker ( http://www.dependencywalker.com/ ), it should point out the missing dlls for you.
For php, \n should work for you!
I'm working on this right now as well. You should also add a datetime of the comment. You'll need this later when you want to sort by most recent.

I believe enum have a .name() in its API, pretty simple to use like this example:
private int security;
public String security(){ return Security.values()[security].name(); }
public void setSecurity(int security){ this.security = security; }
private enum Security {
low,
high
}
With this you can simply call
yourObject.security()
and it returns high/low as String, in this example
ls -lart | tail -n +2 #argument means starting with line 2

You can also test them as a couple.

print "i is 5 and ii is 10"
The link to a function in a dynamic library is resolved when the library is loaded or at run time. Therefore, both the executable file and dynamic library are loaded into memory when the program is run. The memory address at which a dynamic library is loaded cannot be determined in advance, because a fixed address might clash with another dynamic library requiring the same address.
There are two commonly used methods for dealing with this problem:
1.Relocation. All pointers and addresses in the code are modified, if necessary, to fit the actual load address. Relocation is done by the linker and the loader.
2.Position-independent code. All addresses in the code are relative to the current position. Shared objects in Unix-like systems use position-independent code by default. This is less efficient than relocation if program run for a long time, especially in 32-bit mode.
The name "position-independent code" actually implies following:
The code section contains no absolute addresses that need relocation, but only self relative addresses. Therefore, the code section can be loaded at an arbitrary memory address and shared between multiple processes.
The data section is not shared between multiple processes because it often contains writeable data. Therefore, the data section may contain pointers or addresses that need relocation.
All public functions and public data can be overridden in Linux. If a function in the main executable has the same name as a function in a shared object, then the version in main will take precedence, not only when called from main, but also when called from the shared object. Likewise, when a global variable in main has the same name as a global variable in the shared object, then the instance in main will be used, even when accessed from the shared object.
This so-called symbol interposition is intended to mimic the behavior of static libraries.
A shared object has a table of pointers to its functions, called procedure linkage table (PLT) and a table of pointers to its variables called global offset table (GOT) in order to implement this "override" feature. All accesses to functions and public variables go through this tables.
p.s. Where dynamic linking cannot be avoided, there are various ways to avoid the timeconsuming features of the position-independent code.

I was having the same problem here. Found out that the problem was with an Advanced Property of the file. There is there an option with the name 'Compilation Action' (may be not with the exact words, I am translating - my VS is in Portuguese).
My Class1.cs file was there as "Content" and I just had to change it to "Compile" to make it work, and have the classes recognized by the others files in the same project.
A bit of a cleaner way to do this:
SELECT DC.[name]
FROM [sys].[default_constraints] AS DC
WHERE DC.[parent_object_id] = OBJECT_ID('[Schema].[TableName]')
This example demonstrates the difference between the mousemove, mouseenter and mouseover events:
https://jsfiddle.net/z8g613yd/
HTML:
<div onmousemove="myMoveFunction()">
<p>onmousemove: <br> <span id="demo">Mouse over me!</span></p>
</div>
<div onmouseenter="myEnterFunction()">
<p>onmouseenter: <br> <span id="demo2">Mouse over me!</span></p>
</div>
<div onmouseover="myOverFunction()">
<p>onmouseover: <br> <span id="demo3">Mouse over me!</span></p>

}
p {

p span {
background-color: #86fcd4;
padding: 0 20px;
}
JS:
var x = 0;
var y = 0;
var z = 0;
function myMoveFunction() {
document.getElementById("demo").innerHTML = z += 1;
}
function myEnterFunction() {
document.getElementById("demo2").innerHTML = x += 1;
}
function myOverFunction() {
document.getElementById("demo3").innerHTML = y += 1;
}
onmousemove
: occurs every time the mouse pointer is moved over the div element.onmouseenter
: only occurs when the mouse pointer enters the div element.onmouseover
: occurs when the mouse pointer enters the div element,
and its child elements (p and span).If you know it will be only one number in the string, i.e 'hello 12 hi'
, you can try filter
.
For example:
In [1]: int(''.join(filter(str.isdigit, '200 grams')))
Out[1]: 200
In [2]: int(''.join(filter(str.isdigit, 'Counters: 55')))
Out[2]: 55
In [3]: int(''.join(filter(str.isdigit, 'more than 23 times')))
Out[3]: 23
But be carefull !!! :
In [4]: int(''.join(filter(str.isdigit, '200 grams 5')))
Out[4]: 2005
you can add values to specific columns as well, just specify the column names in which you like to add corresponding values:
Insert into Table (Col1, Col2, Col4,col5,Col7) Values ('Va11','Va2','Val4','Val5','Val7');
Make sure the columns you skip dont have not null value type.
For any complex application, I suggest to use an lxc container. lxc containers are 'something in the middle between a chroot on steroids and a full fledged virtual machine'.
For example, here's a way to build 32-bit wine using lxc on an Ubuntu Trusty system:
sudo apt-get install lxc lxc-templates
sudo lxc-create -t ubuntu -n my32bitbox -- --bindhome $LOGNAME -a i386 --release trusty
sudo lxc-start -n my32bitbox
# login as yourself
sudo sh -c "sed s/deb/deb-src/ /etc/apt/sources.list >> /etc/apt/sources.list"
sudo apt-get install devscripts
sudo apt-get build-dep wine1.7
apt-get source wine1.7
cd wine1.7-*
debuild -eDEB_BUILD_OPTIONS="parallel=8" -i -us -uc -b
shutdown -h now # to exit the container
Here is the wiki page about how to build 32-bit wine on a 64-bit host using lxc.

We can say that:
If the manifest package name has changed, the new application will be installed alongside the old application, so they both co-exist on the user’s device at the same time.
If the signing certificate changes, trying to install the new application on to the device will fail until the old version is uninstalled.
As per Google App Update check list : https://support.google.com/googleplay/android-developer/answer/113476?hl=en
Update your apps
Prepare your APK
When you're ready to make changes to your APK, make sure to update your app’s version code as well so that existing users will receive your update.
Use the following checklist to make sure your new APK is ready to update your existing users:
To verify that your APK is using the same certification as the previous version, you can run the following command on both APKs and compare the results:
$ jarsigner -verify -verbose -certs my_application.apk
If the results are identical, you’re using the same key and are ready to continue. If the results are different, you will need to re-sign the APK with the correct key.
Learn more about signing your applications
Upload your APK Once your APK is ready, you can create a new release.
There is also an alternative way to use MarkupExtension
in order to use Binding
for a ConverterParameter
. With this solution you can still use the default IValueConverter
instead of the IMultiValueConverter
because the ConverterParameter
is passed into the IValueConverter
just like you expected in your first sample.
Here is my reusable MarkupExtension
:
/// <summary>
/// <example>
/// <TextBox>
/// <TextBox.Text>
/// <wpfAdditions:ConverterBindableParameter Binding="{Binding FirstName}"
/// Converter="{StaticResource TestValueConverter}"
/// ConverterParameterBinding="{Binding ConcatSign}" />
/// </TextBox.Text>
/// </TextBox>
/// </example>
/// </summary>
[ContentProperty(nameof(Binding))]
public class ConverterBindableParameter : MarkupExtension
{
#region Public Properties
public Binding Binding { get; set; }
public BindingMode Mode { get; set; }
public IValueConverter Converter { get; set; }
public Binding ConverterParameter { get; set; }
#endregion
public ConverterBindableParameter()
{ }
public ConverterBindableParameter(string path)
{
Binding = new Binding(path);
}
public ConverterBindableParameter(Binding binding)
{
Binding = binding;
}
#region Overridden Methods
public override object ProvideValue(IServiceProvider serviceProvider)
{
var multiBinding = new MultiBinding();
Binding.Mode = Mode;
multiBinding.Bindings.Add(Binding);
if (ConverterParameter != null)
{
ConverterParameter.Mode = BindingMode.OneWay;
multiBinding.Bindings.Add(ConverterParameter);
}
var adapter = new MultiValueConverterAdapter
{
Converter = Converter
};
multiBinding.Converter = adapter;
return multiBinding.ProvideValue(serviceProvider);
}
#endregion
[ContentProperty(nameof(Converter))]
private class MultiValueConverterAdapter : IMultiValueConverter
{
public IValueConverter Converter { get; set; }
private object lastParameter;
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
if (Converter == null) return values[0]; // Required for VS design-time
if (values.Length > 1) lastParameter = values[1];
return Converter.Convert(values[0], targetType, lastParameter, culture);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
if (Converter == null) return new object[] { value }; // Required for VS design-time
return new object[] { Converter.ConvertBack(value, targetTypes[0], lastParameter, culture) };
}
}
}
With this MarkupExtension
in your code base you can simply bind the ConverterParameter
the following way:
<Style TargetType="FrameworkElement">
<Setter Property="Visibility">
<Setter.Value>
<wpfAdditions:ConverterBindableParameter Binding="{Binding Tag, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}"
Converter="{StaticResource AccessLevelToVisibilityConverter}"
ConverterParameterBinding="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Tag}" />
</Setter.Value>
</Setter>
Which looks almost like your initial proposal.
Are you hosting the site on iis? if so make sure the account your website runs under has access to local file system?
Straight from msdn .....
The Network Service account has Read and Execute permissions on the IIS server root folder by default. The IIS server root folder is named Wwwroot. This means that an ASP.NET application deployed inside the root folder already has Read and Execute permissions to its application folders. However, if your ASP.NET application needs to use files or folders in other locations, you must specifically enable access.
To provide access to an ASP.NET application running as Network Service, you must grant access to the Network Service account.

As others have said, Stopwatch
is a good class to use here. You can wrap it in a helpful method:
public static TimeSpan Time(Action action)
{
Stopwatch stopwatch = Stopwatch.StartNew();
action();
stopwatch.Stop();
return stopwatch.Elapsed;
}
(Note the use of Stopwatch.StartNew()
. I prefer this to creating a Stopwatch and then calling Start()
in terms of simplicity.) Obviously this incurs the hit of invoking a delegate, but in the vast majority of cases that won't be relevant. You'd then write:
TimeSpan time = StopwatchUtil.Time(() =>
{
// Do some work
});
You could even make an ITimer
interface for this, with implementations of StopwatchTimer,
CpuTimer
etc where available.
Try:
<([^\s]+)(\s[^>]*?)?(?<!/)>
It is similar to yours, but the last >
must not be after a slash, and also accepts h1
.
If you don't want to use the shutil
module you can just use the os
module.
from os import listdir, rmdir, remove
for i in listdir(directoryToRemove):
os.remove(os.path.join(directoryToRemove, i))
rmdir(directoryToRemove) # Now the directory is empty of files
There are a number of libraries available for generating graphs.

I have just wrestled with this for 3 hours. I credit the answer from Dherik (Bonus material about AMQP) for bringing me within striking distance of MY answer, YMMV.
I registered the JavaTimeModule in my object mapper in my SpringBootApplication like this:
@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
ObjectMapper objectMapper = builder.build();
objectMapper.registerModule(new JavaTimeModule());
return objectMapper;
}
However my Instants that were coming over the STOMP connection were still not deserialising. Then I realised I had inadvertantly created a MappingJackson2MessageConverter which creates a second ObjectMapper. So I guess the moral of the story is: Are you sure you have adjusted all your ObjectMappers? In my case I replaced the MappingJackson2MessageConverter.objectMapper with the outer version that has the JavaTimeModule registered, and all is well:
@Autowired
ObjectMapper objectMapper;
@Bean
public WebSocketStompClient webSocketStompClient(WebSocketClient webSocketClient,
StompSessionHandler stompSessionHandler) {
WebSocketStompClient webSocketStompClient = new WebSocketStompClient(webSocketClient);
MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
converter.setObjectMapper(objectMapper);
webSocketStompClient.setMessageConverter(converter);
webSocketStompClient.connect("http://localhost:8080/myapp", stompSessionHandler);
return webSocketStompClient;
}
The webserver is returning an http 500 error code. These errors generally happen when an exception in thrown on the webserver and there's no logic to catch it so it spits out an http 500 error. You can usually resolve the problem by placing try-catch blocks in your code.
Try this (requires access to sys.dm_exec_connections
):
SELECT DISTINCT
local_tcp_port
FROM sys.dm_exec_connections
WHERE local_tcp_port IS NOT NULL
Use anchors instead:
aa=re.match(r"^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$",ip)
These make sure that the start and end of the string are matched at the start and end of the regex. (well, technically, you don't need the starting ^
anchor because it's implicit in the .match()
method).
Then, check if the regex did in fact match before trying to access its results:
if aa:
ip = aa.group()
Of course, this is not a good approach for validating IP addresses (check out gnibbler's answer for a proper method). However, regexes can be useful for detecting IP addresses in a larger string:
ip_candidates = re.findall(r"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b", ip)
Here, the \b
word boundary anchors make sure that the digits don't exceed 3 for each segment.
Just noting this here in case anyone else has a similar issue.
If you're directing a request directly to a JSP, using Apache Tomcat web.xml configuration, then ${requestScope.attr}

If you have a csv file named 'blah.csv' That looks like
a,b,c,d
1,2,3,4
2,3,4,5
3,4,5,6
you know that you can open the file for reading, and create a DictReader with
blah = open('blah.csv', 'r')
reader= csv.DictReader(blah)
Then, you will be able to get the next line with reader.next()
, which should output
{'a':1,'b':2,'c':3,'d':4}
using it again will produce
{'a':2,'b':3,'c':4,'d':5}
However, at this point if you use blah.seek(0)
, the next time you call reader.next()
you will get
{'a':1,'b':2,'c':3,'d':4}
again.
This seems to be the functionality you're looking for. I'm sure there are some tricks associated with this approach that I'm not aware of however. @Brian suggested simply creating another DictReader. This won't work if you're first reader is half way through reading the file, as your new reader will have unexpected keys and values from wherever you are in the file.

Just want to let you guys know, the accepted answer doesn't always work.
Here's an example it will fail.
if <href='/list'>
href = $('css_selector').attr('href')
"/list"
href = document.querySelector('css_selector').href
"http://localhost/list"
or you could append the href you got from jQuery to this
href = document.URL +$('css_selector').attr('href');
or jQuery way
href = $('css_selector').prop('href')
Finally, invoke it to change the browser current page's url
window.location.href = href
or pop it out using window.open(url)
Here's an example in JSFiddle.
A pseudo element works best.
a, a:hover {
position: relative;
text-decoration: none;
}
a:after {
content: '';
display: block;
position: absolute;
height: 0;
top:90%;
left: 0;
right: 0;
border-bottom: solid 1px red;
}
See jsfiddle.
You don't need any extra elements, you can position it as close or far as you want from the text (border-bottom is kinda far for my liking), there aren't any extra colors that show up if your link is over a different colored background (like with the box-shadow trick), and it works in all browsers (text-decoration-color only supports Firefox as of yet).
Possible downside: The link can't be position:static, but that's probably not a problem the vast majority of the time. Just set it to relative and all is good.
You can get other constructors with getConstructor(...).
(For those coming to this question from a search engine), check that your stored procedures declare a custom delimiter, as this is the error that you might see when the engine can't figure out how to terminate a statement:

If you have a database dump and see:
DROP PROCEDURE IF EXISTS prc_test;
CREATE PROCEDURE prc_test( test varchar(50))
BEGIN
SET @sqlstr = CONCAT_WS(' ', 'CREATE DATABASE', test, 'CHARACTER SET utf8 COLLATE utf8_general_ci');
SELECT @sqlstr;
PREPARE stmt FROM @sqlstr;
EXECUTE stmt;
END;
Try wrapping with a custom DELIMITER
:
DROP PROCEDURE IF EXISTS prc_test;
DELIMITER $$
CREATE PROCEDURE prc_test( test varchar(50))
BEGIN
SET @sqlstr = CONCAT_WS(' ', 'CREATE DATABASE', test, 'CHARACTER SET utf8 COLLATE utf8_general_ci');
SELECT @sqlstr;
PREPARE stmt FROM @sqlstr;
EXECUTE stmt;
END;

There's a DTD for HTML 4 at http://www.w3.org/TR/REC-html40/sgml/dtd.html . This DTD is the machine-processable form of the spec, with the limitation that a DTD governs XML and HTML 4, especially the "transient" flavor, permits a lot of things that are not "legal" XML. Still, I consider it comes close to codifying the intent of the specifiers.
<!ELEMENT A - - (%inline;)* -(A) -- anchor -->
<!ENTITY % inline "#PCDATA | %fontstyle; | %phrase; | %special; | %formctrl;">
<!ENTITY % fontstyle "TT | I | B | BIG | SMALL">
<!ENTITY % phrase "EM | STRONG | DFN | CODE | SAMP | KBD | VAR | CITE | ABBR | ACRONYM" >
<!ENTITY % special "A | IMG | OBJECT | BR | SCRIPT | MAP | Q | SUB | SUP | SPAN | BDO">
<!ENTITY % formctrl "INPUT | SELECT | TEXTAREA | LABEL | BUTTON">
I would interpret the tags listed in this hierarchy to be the total of tags allowed.
While the spec may say "inline elements," I'm pretty sure it's not intended that you can get around the intent by declaring the display type of a block element to be inline. Inline tags have different semantics no matter how you may abuse them.
On the other hand, I find it intriguing that the inclusion of special
seems to allow nesting A
elements. There's probably some strong wording in the spec that disallows this even if it's XML-syntactically correct but I won't pursue this further as it's not the topic of the question.
The difference is the implicit conversion when using AddWithValue. If you know that your executing SQL query (stored procedure) is accepting a value of type int, nvarchar, etc, there's no reason in re-declaring it in your code.
For complex type scenarios (example would be DateTime, float), I'll probably use Add since it's more explicit but AddWithValue for more straight-forward type scenarios (Int to Int).
By looking at your code, I sense you are using JSONLIB. If that was the case, look at the following snippet to convert json array to java array..
JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON( input );
JsonConfig jsonConfig = new JsonConfig();
jsonConfig.setArrayMode( JsonConfig.MODE_OBJECT_ARRAY );
jsonConfig.setRootClass( Integer.TYPE );
int[] output = (int[]) JSONSerializer.toJava( jsonArray, jsonConfig );
You could use the isNaN Function. It returns true if the data is not a number. That would be something like that:
function checkInp()
{
var x=document.forms["myForm"]["age"].value;
if (isNaN(x)) // this is the code I need to change
{
alert("Must input numbers");
return false;
}
}
Note: isNan considers 10.2 as a valid number.
The short answer is:
int nBits = ceil(log2(N));
That's simply because pow(2, nBits) is slightly bigger than N.
Along with WSDL, I had xsd files. The above did not work in my case gave error. It worked as follows

There's a simple online tool that can do this called sqlizer.io.
You upload an XLSX file to it, enter a sheet name and cell range, and it will generate a CREATE TABLE statement and a bunch of INSERT statements to import all your data into a MySQL database.

In case of upgrading your python on mac os 10.7 and pkg_resources doesn't work, the simplest way to fix this is just reinstall setuptools as Ned mentioned above.
sudo pip install setuptools --upgrade
or sudo easy_install install setuptools --upgrade
This can be done similarly in Python using lists, (note that the whole list is shuffled in place).
import random
with open("datafile.txt", "rb") as f:
data = f.read().split('\n')
random.shuffle(data)
train_data = data[:50]
test_data = data[50:]
Several definitions of the same name
<C-w>g<C-]>
open the definition in a split, but also do :tjump
which either goes to the definition or, if there are several definitions, presents you with a list of definitions to choose from.
xxx >& filename
Or do this to see everything on the screen and have it go to your file:
xxx | & tee ./logfile

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.
It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.
There's really no reason to choose any of the other options for a new application.
You can use the MSXML Base64 encoding functionality as described at www.nonhostile.com/howto-encode-decode-base64-vb6.asp:
Function EncodeBase64(text As String) As String
Dim arrData() As Byte
arrData = StrConv(text, vbFromUnicode)
Dim objXML As MSXML2.DOMDocument
Dim objNode As MSXML2.IXMLDOMElement
Set objXML = New MSXML2.DOMDocument
Set objNode = objXML.createElement("b64")
objNode.dataType = "bin.base64"
objNode.nodeTypedValue = arrData
EncodeBase64 = objNode.Text
Set objNode = Nothing
Set objXML = Nothing
End Function
Another scenario where this could happen is when you are launching an instance of eclipse (for debug etc.) from a host eclipse - in which case, altering the project's level or JRE library on the project's classpath alone doesn't help. What matters is the JRE used to launch the target eclipse environment.
When working with Swift, you can use the enum
UIUserInterfaceIdiom
, defined as:
enum UIUserInterfaceIdiom : Int {
case unspecified
case phone // iPhone and iPod touch style UI
case pad // iPad style UI (also includes macOS Catalyst)
}
So you can use it as:
UIDevice.current.userInterfaceIdiom == .pad
UIDevice.current.userInterfaceIdiom == .phone
UIDevice.current.userInterfaceIdiom == .unspecified
Or with a Switch statement:
switch UIDevice.current.userInterfaceIdiom {
case .phone:
// It's an iPhone
case .pad:
// It's an iPad (or macOS Catalyst)
@unknown default:
// Uh, oh! What could it be?
}
UI_USER_INTERFACE_IDIOM()
is an Objective-C macro, which is defined as:
#define UI_USER_INTERFACE_IDIOM() \ ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] ? \ [[UIDevice currentDevice] userInterfaceIdiom] : \ UIUserInterfaceIdiomPhone)
Also, note that even when working with Objective-C, the UI_USER_INTERFACE_IDIOM()
macro is only required when targeting iOS 3.2 and below. When deploying to iOS 3.2 and up, you can use [UIDevice userInterfaceIdiom]
directly.
The definition given above of the height is incorrect. That is the definition of the depth.
"The depth of a node M in a tree is the length of the path from the root of the tree to M. The height of a tree is one more than the depth of the deepest node in the tree. All nodes of depth d are at level d in the tree. The root is the only node at level 0, and its depth is 0."

I got it to work with:
SQLiteDatabase db= this.getWritableDatabase();
db.delete(TABLE_NAME, null, null);
May be this will be usefull for u: ReGExp on-line editor
Type it in one cell, copy that cell, select all the cells you want to fill, and paste.
Alternatively, type it in one cell, select the black square in the bottom-right of that cell, and drag down.
In an instance where you want to set a placeholder and not have a default value be selected, you can use this option.
<select defaultValue={'DEFAULT'} >
<option value="DEFAULT" disabled>Choose a salutation ...</option>
<option value="1">Mr</option>
<option value="2">Mrs</option>
<option value="3">Ms</option>
<option value="4">Miss</option>
<option value="5">Dr</option>
</select>
Here the user is forced to pick an option!
EDIT
If this is a controlled component
In this case unfortunately you will have to use both defaultValue and value violating React a bit. This is because react by semantics does not allow setting a disabled value as active.
function TheSelectComponent(props){
let currentValue = props.curentValue || "DEFAULT";
return(
<select value={currentValue} defaultValue={'DEFAULT'} onChange={props.onChange}>
<option value="DEFAULT" disabled>Choose a salutation ...</option>
<option value="1">Mr</option>
<option value="2">Mrs</option>
<option value="3">Ms</option>
<option value="4">Miss</option>
<option value="5">Dr</option>
</select>
)
}
I do not know if it is on SQL, etc... on M$ACCESS help there is a function called MAXA(Value1;Value2;...)
that is supposed to do such.
Hope can help someone.
P.D.: Values can be columns or calculated ones, etc.
git archive
also works with remote repository.
git archive --format=tar \
--remote=ssh://remote_server/remote_repository master | tar -xf -
To export particular path inside the repo add as many paths as you wish as last argument to git, e.g.:
git archive --format=tar \
--remote=ssh://remote_server/remote_repository master path1/ path2/ | tar -xv
You were close. Add this code in the UserForm_Initialize()
event handler:
tbxDate.Value = Date
To have a more in-depth knowledge of what's happening, I created the following example. Have a look at the activity_main.xml and content_profile.xml files.
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/content_profile" />
</LinearLayout>
content_profile.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Howdy" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hi there" />
</LinearLayout>
In here, the entire layout file when inflated looks like this.
<LinearLayout>
<LinearLayout>
<TextView />
<TextView />
</LinearLayout>
</LinearLayout>
See that there is a LinearLayout inside the parent LinearLayout which doesn't serve any purpose and is redundant. A look at the layout through Layout Inspector tool clearly explains this.
content_profile.xml after updating the code to use merge instead of a ViewGroup like LinearLayout.
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Howdy" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hi there" />
</merge>
Now our layout looks like this
<LinearLayout>
<TextView />
<TextView />
</LinearLayout>
Here we see that the redundant LinearLayout ViewGroup is removed. Now Layout Inspector tool gives the following layout hierarchy.
So always try to use merge when your parent layout can position your child layouts, or more precisely use merge when you understand that there is going to be a redundant view group in the hierarchy.
<select id="example">
<option value="">please select</option>
<option value="0" >one</option>
<option value="1">two</option>
</select>
if (condition){
//you can't select
$("#example").find("option").css("display","none");
}else{
//you can select
$("#example").find("option").css("display","block");
}
Avro is a row-based storage format for Hadoop.
Parquet is a column-based storage format for Hadoop.
If your use case typically scans or retrieves all of the fields in a row in each query, Avro is usually the best choice.
If your dataset has many columns, and your use case typically involves working with a subset of those columns rather than entire records, Parquet is optimized for that kind of work.
Try this:
TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')
You might be better served by using a JavaScript framework, that has functions to return such information (and so much more!) in a browser-independant fashion. Here are a few:
With these frameworks, you could do something like:
$('id-of-img').top
to get the y-pixel coordinate of the image.
This will make the div fixed at the bottom of the page but in case the page is long it will only be visible when you scroll down.
<style type="text/css">
#footer {
position : absolute;
bottom : 0;
height : 40px;
margin-top : 40px;
}
</style>
<div id="footer">I am footer</div>
The height and margin-top should be the same so that the footer doesnt show over the content.
You can wrap loop body in additional repeat until true
and then use do break end
inside for effect of continue. Naturally, you'll need to set up additional flags if you also intend to really break
out of loop as well.
This will loop 5 times, printing 1, 2, and 3 each time.
for idx = 1, 5 do
repeat
print(1)
print(2)
print(3)
do break end -- goes to next iteration of for
print(4)
print(5)
until true
end
This construction even translates to literal one opcode JMP

You can't.
As a workaround you can use a // @ts-nocheck
comment at the top of a file to disable type-checking for that file: https://devblogs.microsoft.com/typescript/announcing-typescript-3-7-beta/
So to disable checking for a block (function, class, etc.), you can move it into its own file, then use the comment/flag above. (This isn't as flexible as block-based disabling of course, but it's the best option available at the moment.)
On GitHub, you can use HTML directly instead of Markdown:
<a href="url"><img src="http://url.to/image.png" align="left" height="48" width="48" ></a>
This should make it.
You can define assertNotRaises
by reusing about 90% of the original implementation of assertRaises
in the unittest
module. With this approach, you end up with an assertNotRaises
method that, aside from its reversed failure condition, behaves identically to assertRaises
.
It turns out to be surprisingly easy to add an assertNotRaises
method to unittest.TestCase
(it took me about 4 times as long to write this answer as it did the code). Here's a live demo of the assertNotRaises
method in action. Just like assertRaises
, you can either pass a callable and args to assertNotRaises
, or you can use it in a with
statement. The live demo includes a test cases that demonstrates that assertNotRaises
works as intended.
The implementation of assertRaises
in unittest
is fairly complicated, but with a little bit of clever subclassing you can override and reverse its failure condition.
assertRaises
is a short method that basically just creates an instance of the unittest.case._AssertRaisesContext
class and returns it (see its definition in the unittest.case
module). You can define your own _AssertNotRaisesContext
class by subclassing _AssertRaisesContext
and overriding its __exit__
method:
import traceback
from unittest.case import _AssertRaisesContext
class _AssertNotRaisesContext(_AssertRaisesContext):
def __exit__(self, exc_type, exc_value, tb):
if exc_type is not None:
self.exception = exc_value.with_traceback(None)
try:
exc_name = self.expected.__name__
except AttributeError:
exc_name = str(self.expected)
if self.obj_name:
self._raiseFailure("{} raised by {}".format(exc_name,
self.obj_name))
else:
self._raiseFailure("{} raised".format(exc_name))
else:
traceback.clear_frames(tb)
return True
Normally you define test case classes by having them inherit from TestCase
. If you instead inherit from a subclass MyTestCase
:
class MyTestCase(unittest.TestCase):
def assertNotRaises(self, expected_exception, *args, **kwargs):
context = _AssertNotRaisesContext(expected_exception, self)
try:
return context.handle('assertNotRaises', args, kwargs)
finally:
context = None
all of your test cases will now have the assertNotRaises
method available to them.
As some sugested you can use apache or jax-ws. You can also use tools that generate code from WSDL such as ws-import but in my opinion the best way to consume web service is to create a dynamic client and invoke only operations you want not everything from wsdl. You can do this by creating a dynamic client: Sample code:
String endpointUrl = ...;
QName serviceName = new QName("http://com/ibm/was/wssample/echo/",
"EchoService");
QName portName = new QName("http://com/ibm/was/wssample/echo/",
"EchoServicePort");
/** Create a service and add at least one port to it. **/
Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointUrl);
/** Create a Dispatch instance from a service.**/
Dispatch<SOAPMessage> dispatch = service.createDispatch(portName,
SOAPMessage.class, Service.Mode.MESSAGE);
/** Create SOAPMessage request. **/
// compose a request message
MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
// Create a message. This example works with the SOAPPART.
SOAPMessage request = mf.createMessage();
SOAPPart part = request.getSOAPPart();
// Obtain the SOAPEnvelope and header and body elements.
SOAPEnvelope env = part.getEnvelope();
SOAPHeader header = env.getHeader();
SOAPBody body = env.getBody();
// Construct the message payload.
SOAPElement operation = body.addChildElement("invoke", "ns1",
"http://com/ibm/was/wssample/echo/");
SOAPElement value = operation.addChildElement("arg0");
value.addTextNode("ping");
request.saveChanges();
/** Invoke the service endpoint. **/
SOAPMessage response = dispatch.invoke(request);
/** Process the response. **/
If you have the table definition to have an IDENTITY column e.g. IDENTITY(1,1) then don't include MyId in your INSERT INTO statement. The point of IDENTITY is it gives it the next unused value as the primary key value.
insert into MYDB.dbo.MainTable (MyFirstName, MyLastName, MyAddress, MyPort)
values(@myFirstName, @myLastName, @myAddress, @myPort)
There is then no need to pass the @MyId parameter into your stored procedure either. So change it to:
CREATE PROCEDURE [dbo].[sp_Test]
@myFirstName nvarchar(50)
,@myLastName nvarchar(50)
,@myAddress nvarchar(MAX)
,@myPort int
AS
If you want to know what the ID of the newly inserted record is add
SELECT @@IDENTITY
to the end of your procedure. e.g. http://msdn.microsoft.com/en-us/library/ms187342.aspx
You will then be able to pick this up in which ever way you are calling it be it SQL or .NET.
P.s. a better way to show you table definision would have been to script the table and paste the text into your stackoverflow browser window because your screen shot is missing the column properties part where IDENTITY is set via the GUI. To do that right click the table 'Script Table as' --> 'CREATE to' --> Clipboard. You can also do File or New Query Editor Window (all self explanitory) experient and see what you get.
if your array looks like
array = [
{:name => "Hitesh" , :age => 27 , :place => "xyz"} ,
{:name => "John" , :age => 26 , :place => "xtz"} ,
{:name => "Anil" , :age => 26 , :place => "xsz"}
]
And you Want To know if some value is already present in your array. Use Find Method
array.find {|x| x[:name] == "Hitesh"}
This will return object if Hitesh is present in name otherwise return nil
I think I observed a similar problem: some processes started, seemed to run successfully but never completed. The function waitFor() was waiting forever except if I killed the process in Task Manager.
However, everything worked well in cases the length of the command line was 127 characters or shorter. If long file names are inevitable you may want to use environmental variables, which may allow you keeping the command line string short. You can generate a batch file (using FileWriter) in which you set your environmental variables before calling the program you actually want to run.
The content of such a batch could look like:
set INPUTFILE="C:\Directory 0\Subdirectory 1\AnyFileName"
set OUTPUTFILE="C:\Directory 2\Subdirectory 3\AnotherFileName"
set MYPROG="C:\Directory 4\Subdirectory 5\ExecutableFileName.exe"
%MYPROG% %INPUTFILE% %OUTPUTFILE%
Last step is running this batch file using Runtime.
I know this question is older but I was looking thru the answers and thought that I might be able to expand on the "dynamic" portion of the problem and possibly help someone out.
First and foremost I built this solution to solve a problem a couple of coworkers were having with inconstant and large data sets needing to be pivoted quickly.
This solution requires the creation of a stored procedure so if that is out of the question for your needs please stop reading now.
This procedure is going to take in the key variables of a pivot statement to dynamically create pivot statements for varying tables, column names and aggregates. The Static column is used as the group by / identity column for the pivot(this can be stripped out of the code if not necessary but is pretty common in pivot statements and was necessary to solve the original issue), the pivot column is where the end resultant column names will be generated from, and the value column is what the aggregate will be applied to. The Table parameter is the name of the table including the schema (schema.tablename) this portion of the code could use some love because it is not as clean as I would like it to be. It worked for me because my usage was not publicly facing and sql injection was not a concern. The Aggregate parameter will accept any standard sql aggregate 'AVG', 'SUM', 'MAX' etc. The code also defaults to MAX as an aggregate this is not necessary but the audience this was originally built for did not understand pivots and were typically using max as an aggregate.
Lets start with the code to create the stored procedure. This code should work in all versions of SSMS 2005 and above but I have not tested it in 2005 or 2016 but I can not see why it would not work.
create PROCEDURE [dbo].[USP_DYNAMIC_PIVOT]
(
@STATIC_COLUMN VARCHAR(255),
@PIVOT_COLUMN VARCHAR(255),
@VALUE_COLUMN VARCHAR(255),
@TABLE VARCHAR(255),
@AGGREGATE VARCHAR(20) = null
)
AS
BEGIN
SET NOCOUNT ON;
declare @AVAIABLE_TO_PIVOT NVARCHAR(MAX),
@SQLSTRING NVARCHAR(MAX),
@PIVOT_SQL_STRING NVARCHAR(MAX),
@TEMPVARCOLUMNS NVARCHAR(MAX),
@TABLESQL NVARCHAR(MAX)
if isnull(@AGGREGATE,'') = ''
begin
SET @AGGREGATE = 'MAX'
end
SET @PIVOT_SQL_STRING = 'SELECT top 1 STUFF((SELECT distinct '', '' + CAST(''[''+CONVERT(VARCHAR,'+ @PIVOT_COLUMN+')+'']'' AS VARCHAR(50)) [text()]
FROM '+@TABLE+'
WHERE ISNULL('+@PIVOT_COLUMN+','''') <> ''''
FOR XML PATH(''''), TYPE)
.value(''.'',''NVARCHAR(MAX)''),1,2,'' '') as PIVOT_VALUES
from '+@TABLE+' ma
ORDER BY ' + @PIVOT_COLUMN + ''
declare @TAB AS TABLE(COL NVARCHAR(MAX) )
INSERT INTO @TAB EXEC SP_EXECUTESQL @PIVOT_SQL_STRING, @AVAIABLE_TO_PIVOT
SET @AVAIABLE_TO_PIVOT = (SELECT * FROM @TAB)
SET @TEMPVARCOLUMNS = (SELECT replace(@AVAIABLE_TO_PIVOT,',',' nvarchar(255) null,') + ' nvarchar(255) null')
SET @SQLSTRING = 'DECLARE @RETURN_TABLE TABLE ('+@STATIC_COLUMN+' NVARCHAR(255) NULL,'+@TEMPVARCOLUMNS+')
INSERT INTO @RETURN_TABLE('+@STATIC_COLUMN+','+@AVAIABLE_TO_PIVOT+')
select * from (
SELECT ' + @STATIC_COLUMN + ' , ' + @PIVOT_COLUMN + ', ' + @VALUE_COLUMN + ' FROM '+@TABLE+' ) a
PIVOT
(
'+@AGGREGATE+'('+@VALUE_COLUMN+')
FOR '+@PIVOT_COLUMN+' IN ('+@AVAIABLE_TO_PIVOT+')
) piv
SELECT * FROM @RETURN_TABLE'
EXEC SP_EXECUTESQL @SQLSTRING
END
Next we will get our data ready for the example. I have taken the data example from the accepted answer with the addition of a couple of data elements to use in this proof of concept to show the varied outputs of the aggregate change.
create table temp
(
date datetime,
category varchar(3),
amount money
)
insert into temp values ('1/1/2012', 'ABC', 1000.00)
insert into temp values ('1/1/2012', 'ABC', 2000.00) -- added
insert into temp values ('2/1/2012', 'DEF', 500.00)
insert into temp values ('2/1/2012', 'DEF', 1500.00) -- added
insert into temp values ('2/1/2012', 'GHI', 800.00)
insert into temp values ('2/10/2012', 'DEF', 700.00)
insert into temp values ('2/10/2012', 'DEF', 800.00) -- addded
insert into temp values ('3/1/2012', 'ABC', 1100.00)
The following examples show the varied execution statements showing the varied aggregates as a simple example. I did not opt to change the static, pivot, and value columns to keep the example simple. You should be able to just copy and paste the code to start messing with it yourself
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','sum'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','max'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','avg'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','min'
This execution returns the following data sets respectively.
You should be able to use a var_dump() within a pre tag. Otherwise you could look into using a library like dump_r.php: https://github.com/leeoniya/dump_r.php
My solution is incorrect. OP was looking for a solution formatted with spaces to store in a log file.
A solution might be to use output buffering with var_dump, then str_replace() all the tabs with spaces to format it in the log file.
If the methods above don't work, you can also tell Python to ignore portions of a string that it can't convert to utf-8:
stringnamehere.decode('utf-8', 'ignore')
This works for me:
CSS
.form-group.required.control-label:before{
content: "*";
color: red;
}
OR
.form-group.required.control-label:after{
content: "*";
color: red;
}
Basic HTML
<div class="form-group required control-label">
<input class="form-control" />
</div>
Assuming you want to shift right by L
bits, and the input x
is a number with N
bits:
unsigned ror(unsigned x, int L, int N)
{
unsigned lsbs = x & ((1 << L) - 1);
return (x >> L) | (lsbs << (N-L));
}

BigDecimal is the best data type to use for currency.
There are a whole lot of containers for currency, but they all use BigDecimal as the underlying data type. You won't go wrong with BigDecimal, probably using BigDecimal.ROUND_HALF_EVEN rounding.
Based on cletus's answer you may create new extension.

You cannot (at least at the moment) use parseInt
inside angular expressions, as they're not evaluated directly. Quoting the doc:
Angular does not use JavaScript's
eval()
to evaluate expressions. Instead Angular's$parse
service processes these expressions.Angular expressions do not have access to global variables like
window
,document
orlocation
. This restriction is intentional. It prevents accidental access to the global state – a common source of subtle bugs.
So you can define a total()
method in your controller, then use it in the expression:
// ... somewhere in controller
$scope.total = function() {
return parseInt($scope.num1) + parseInt($scope.num2)
}
// ... in HTML
Total: {{ total() }}
Still, that seems to be rather bulky for a such a simple operation as adding the numbers. The alternative is converting the results with -0
op:
Total: {{num1-0 + (num2-0)|number}}
... but that'll obviously won't parseInt values, only cast them to Numbers (|number
filter prevents showing null
if this cast results in NaN
). So choose the approach that suits your particular case.
What have you tried? This should work.

I would like to suggest you to use HighCharts. It's just awesome and easy to integrate.
Example:
HTML:
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>
Script:
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Monthly Average Rainfall'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: {
categories: [
'Jan',
'Feb',
'Mar',
'Apr',
'May',
'Jun',
'Jul',
'Aug',
'Sep',
'Oct',
'Nov',
'Dec'
]
},
yAxis: {
min: 0,
title: {
text: 'Rainfall (mm)'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Tokyo',
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}, {
name: 'New York',
data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]
}, {
name: 'London',
data: [48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2]
}, {
name: 'Berlin',
data: [42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4, 47.6, 39.1, 46.8, 51.1]
}]
});
});
And here is the fiddle .
for l in list1:
val = 50 - l[0] + l[1] - l[2]
print "val:", val
Loop through list and do operation on the sublist as you wanted.
Use the MultiValueDict's get
method. This is also present on standard dicts and is a way to fetch a value while providing a default if it does not exist.
is_private = request.POST.get('is_private', False)
Generally,
my_var = dict.get(<key>, <default>)
Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.
Some things to keep in mind, use single quotes '
when dealing with single characters, and double "
for strings. Also it is a bad habit to use global variables when not necessary.
Have fun!
It can also be due to a duplicate entry in any of the tables that are used.
You can style it by the following way:
echo "<p style='color:red;'>" . $ip['cityName'] . "</p>";
echo "<p style='color:red;'>" . $ip['countryName'] . "</p>";
angular.element(document.body).injector().get('serviceName')
AngularJS uses Dependency Injection (DI) to inject services/factories into your components,directives and other services. So what you need to do to get a service is to get the injector of AngularJS first (the injector is responsible for wiring up all the dependencies and providing them to components).
To get the injector of your app you need to grab it from an element that angular is handling. For example if your app is registered on the body element you call injector = angular.element(document.body).injector()
From the retrieved injector
you can then get whatever service you like with injector.get('ServiceName')
More information on that in this answer: Can't retrieve the injector from angular
And even more here: Call AngularJS from legacy code
Another useful trick to get the $scope
of a particular element.
Select the element with the DOM inspection tool of your developer tools and then run the following line ($0
is always the selected element):
angular.element($0).scope()
Use gettimeofday()
to get the time in seconds and microseconds. Combining and rounding to milliseconds is left as an exercise.
To get your radio button to list horizontally , just add
RepeatDirection="Horizontal"
to your .aspx file where the asp:radiobuttonlist is being declared.
Situations where you want to insert a lot of items into anywhere but the end of a sequence repeatedly.

I got this error when I was trying to write a javascript bookmarklet. I couldn't figure out what was causing it. But eventually I tried URL encoding the bookmarklet, via the following website: http://mrcoles.com/bookmarklet/ and then the error went away, so it must have been a problem with certain characters in the javascript code being interpreted as special URL control characters.
The documentation for START_STICKY
and START_NOT_STICKY
is quite straightforward.
If this service's process is killed while it is started (after returning from
onStartCommand(Intent, int, int))
, then leave it in the started state but don't retain this delivered intent. Later the system will try to re-create the service. Because it is in the started state, it will guarantee to callonStartCommand(Intent, int, int)
after creating the new service instance; if there are not any pending start commands to be delivered to the service, it will be called with a null intent object, so you must take care to check for this.This mode makes sense for things that will be explicitly started and stopped to run for arbitrary periods of time, such as a service performing background music playback.
Example: Local Service Sample
If this service's process is killed while it is started (after returning from
onStartCommand(Intent, int, int))
, and there are no new start intents to deliver to it, then take the service out of the started state and don't recreate until a future explicit call toContext.startService(Intent)
. The service will not receive aonStartCommand(Intent, int, int)
call with anull
Intent because it will not be re-started if there are no pending Intents to deliver.This mode makes sense for things that want to do some work as a result of being started, but can be stopped when under memory pressure and will explicit start themselves again later to do more work. An example of such a service would be one that polls for data from a server: it could schedule an alarm to poll every
N
minutes by having the alarm start its service. When itsonStartCommand(Intent, int, int)
is called from the alarm, it schedules a new alarm for N minutes later, and spawns a thread to do its networking. If its process is killed while doing that check, the service will not be restarted until the alarm goes off.
Example: ServiceStartArguments.java
Surprisingly, many of the answers don't give complete working code. Here it is:
public static void createFile(String fullPath) throws IOException {
File file = new File(fullPath);
file.getParentFile().mkdirs();
file.createNewFile();
}
public static void main(String [] args) throws Exception {
String path = "C:/donkey/bray.txt";
createFile(path);
}
According to jquery standard you can create plugin as follow:
(function($) {
//methods starts here....
var methods = {
init : function(method,options) {
this.loadKeywords.settings = $.extend({}, this.loadKeywords.defaults, options);
methods[method].apply( this, Array.prototype.slice.call( arguments, 1 ));
$loadkeywordbase=$(this);
},
show : function() {
//your code here.................
},
getData : function() {
//your code here.................
}
} // do not put semi colon here otherwise it will not work in ie7
//end of methods
//main plugin function starts here...
$.fn.loadKeywords = function(options,method) {
if (methods[method]) {
return methods[method].apply(this, Array.prototype.slice.call(
arguments, 1));
} else if (typeof method === 'object' || !method) {
return methods.init.apply(this, arguments);
} else {
$.error('Method ' + method + ' does not ecw-Keywords');
}
};
$.fn.loadKeywords.defaults = {
keyName: 'Messages',
Options: '1',
callback: '',
};
$.fn.loadKeywords.settings = {};
//end of plugin keyword function.
})(jQuery);
How to call this plugin?
1.$('your element').loadKeywords('show',{'callback':callbackdata,'keyName':'myKey'}); // show() will be called

Instead of typing each time, you can;
[1] Create a generic print method inside Spark Shell.
def p(rdd: org.apache.spark.rdd.RDD[_]) = rdd.foreach(println)
[2] Or even better, using implicits, you can add the function to RDD class to print its contents.
implicit class Printer(rdd: org.apache.spark.rdd.RDD[_]) {
def print = rdd.foreach(println)
}
Example usage:
val rdd = sc.parallelize(List(1,2,3,4)).map(_*2)
p(rdd) // 1
rdd.print // 2
Output:
2

Important
This only makes sense if you are working in local mode and with a small amount of data set. Otherwise, you either will not be able to see the results on the client or run out of memory because of the big dataset result.
With a simple call of clear() it appears in the DOM that the corresponding input/textarea component still has its old value, so any following changes on that component (e.g. filling the component with a new value) will not be processed in time.
If you take a look in the selenium source code you'll find that the clear()-method is documented with the following comment:
/** If this element is a text entry element, this will clear the value. Has no effect on other elements. Text entry elements are INPUT and TEXTAREA elements. Note that the events fired by this event may not be as you'd expect. In particular, we don't fire any keyboard or mouse events. If you want to ensure keyboard events are fired, consider using something like {@link #sendKeys(CharSequence...)} with the backspace key. To ensure you get a change event, consider following with a call to {@link #sendKeys(CharSequence...)} with the tab key. */
So using this helpful hint to clear an input/textarea (component that already has a value) AND assign a new value to it, you'll get some code like the following:
public void waitAndClearFollowedByKeys(By by, CharSequence keys) {
LOG.debug("clearing element");
wait(by, true).clear();
sendKeys(by, Keys.BACK_SPACE.toString() + keys);
}
public void sendKeys(By by, CharSequence keysToSend) {
WebElement webElement = wait(by, true);
LOG.info("sending keys '{}' to {}", escapeProperly(keysToSend), by);
webElement.sendKeys(keysToSend);
LOG.info("keys sent");
}
private String escapeProperly(CharSequence keysToSend) {
String result = "" + keysToSend;
result = result.replace(Keys.TAB, "\\t");
result = result.replace(Keys.ENTER, "\\n");
result = result.replace(Keys.RETURN, "\\r");
return result;
}
Sorry for this code being Java and not Python. Also, I had to skip out an additional "waitUntilPageIsReady()-method that would make this post way too long.
Hope this helps you on your journey with Selenium!
I meet this problem and find there are some Chinese characters in my path. After change these characters into English , the problem solved.
I saw this and in CSS3 you can now place code in like this. Lets say I want it to cover the whole background I would do something like this. Then with hsla(0,0%,100%,0.70)
or rgba you use a white background with whatever percentage saturation or opacity to get the look you desire.
.body{
background-attachment: fixed;
background-image: url(../images/Store1.jpeg);
display: block;
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: 1;
background-color: hsla(0,0%,100%,0.70);
background-blend-mode: overlay;
background-repeat: no-repeat;
}
I just put this
$result = mb_convert_encoding($result,'UTF-8','UTF-8');
$result = json_decode($result);
and it's working
