Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
In my case downgrading @angular/animations worked, if you can afford to do that, run the command
npm i @angular/[email protected]
Or use another version that might work for you from the Versions tab here: https://www.npmjs.com/package/@angular/animations
Hi the following solve my same problem absolutely (import/export and so on):
Fix Bug Phpmyadmin [plugin_interface.lib.php] + Php7.2 + Ubuntu 16.04
so... under ubuntu 18.04, mysql, php7.2: Terminal:
sudo gedit /usr/share/phpmyadmin/libraries/plugin_interface.lib.php
Find the following line(ctrl+f):
if ($options != null && count($options) > 0) {
it was on line #551 for me
and change for following:
if ($options != null && count((array)$options) > 0) {
ctrl+s for save the changes
and in terminal: ctrl+c for get back promt...
and: sudo systemctl restart apache2
"I think in new php version.It can’t use count() or sizeof() with un array type. Force parameter to array is easy way to solve this bug,..."
Thanks for the original author for the problem solving! I try to share it!
Angular Router provides method parseUrl(url: string) that parses url into UrlTree. One of the properties of UrlTree are queryParams. So you can do sth like:
this.router.parseUrl(this.router.url).queryParams[key] || '';
protected void onCreate(Bundle savedInstanceState) { /* * Your OnCreate */ Intent intent = getIntent(); String action = intent.getAction(); String type = intent.getType();
//VIEW"
if (Intent.ACTION_VIEW.equals(action) && type != null) {viewhekper(intent);//Handle text being sent}
ECMAScript 6 introduced the let
statement. You can use it in a for
statement.
var ids:string = [];
for(let result of this.results){
ids.push(result.Id);
}
This worked for me (I am using Postgres) in Groovy:
@RestResource(path="namespaceAndNameAndRawStateContainsMostRecentVersion", rel="namespaceAndNameAndRawStateContainsMostRecentVersion")
@Query(nativeQuery=true,
countQuery="""
SELECT COUNT(1)
FROM
(
SELECT
ROW_NUMBER() OVER (
PARTITION BY name, provider_id, state
ORDER BY version DESC) version_partition,
*
FROM mydb.mytable
WHERE
(name ILIKE ('%' || :name || '%') OR (:name = '')) AND
(namespace ILIKE ('%' || :namespace || '%') OR (:namespace = '')) AND
(state = :state OR (:state = ''))
) t
WHERE version_partition = 1
""",
value="""
SELECT id, version, state, name, internal_name, namespace, provider_id, config, create_date, update_date
FROM
(
SELECT
ROW_NUMBER() OVER (
PARTITION BY name, provider_id, state
ORDER BY version DESC) version_partition,
*
FROM mydb.mytable
WHERE
(name ILIKE ('%' || :name || '%') OR (:name = '')) AND
(namespace ILIKE ('%' || :namespace || '%') OR (:namespace = '')) AND
(state = :state OR (:state = ''))
) t
WHERE version_partition = 1
/*#{#pageable}*/
""")
public Page<Entity> findByNamespaceContainsAndNameContainsAndRawStateContainsMostRecentVersion(@Param("namespace")String namespace, @Param("name")String name, @Param("state")String state, Pageable pageable)
The key here was to use: /*#{#pageable}*/
It allows me to do sorting and pagination. You can test it by using something like this: http://localhost:8080/api/v1/entities/search/namespaceAndNameAndRawStateContainsMostRecentVersion?namespace=&name=&state=published&page=0&size=3&sort=name,desc
Watch out for this issue: Spring Pageable does not translate @Column name
Without overriding EF track system, you can also Detach the 'local' entry and attach your updated entry before saving :
//
var local = _context.Set<YourEntity>()
.Local
.FirstOrDefault(entry => entry.Id.Equals(entryId));
// check if local is not null
if (local != null)
{
// detach
_context.Entry(local).State = EntityState.Detached;
}
// set Modified flag in your entry
_context.Entry(entryToUpdate).State = EntityState.Modified;
// save
_context.SaveChanges();
UPDATE: To avoid code redundancy, you can do an extension method :
public static void DetachLocal<T>(this DbContext context, T t, string entryId)
where T : class, IIdentifier
{
var local = context.Set<T>()
.Local
.FirstOrDefault(entry => entry.Id.Equals(entryId));
if (!local.IsNull())
{
context.Entry(local).State = EntityState.Detached;
}
context.Entry(t).State = EntityState.Modified;
}
My IIdentifier
interface has just an Id
string property.
Whatever your Entity, you can use this method on your context :
_context.DetachLocal(tmodel, id);
_context.SaveChanges();
In the constructor of
public class ErrorEventArg : EventArgs
You have to add "base" as follows:
public ErrorEventArg(string errorMsg, string lastQuery) : base (string errorMsg, string lastQuery)
{
ErrorMsg = errorMsg;
LastQuery = lastQuery;
}
That solved it for me
I managed to fix it finally. The problem is not related to HikariCP.
The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional
or enveloping all the logic in a single call to transactional service method seem to solve the problem.
Put this on routes.php file:
\Event::listen('Illuminate\Database\Events\QueryExecuted', function ($query) {
echo'<pre>';
var_dump($query->sql);
var_dump($query->bindings);
var_dump($query->time);
echo'</pre>';
});
Submitted by msurguy, source code in this page. You will find this fix-code for laravel 5.2 in comments.
I encountered the same problem and finally found out that the <tx:annotaion-driven />
was not defined within the [dispatcher]-servlet.xml
where component-scan element enabled @service
annotated class.
Simply put <tx:annotaion-driven />
with component-scan element together, the problem disappeared.
This one did work for me in ES 1.7.5:
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.xcontent.XContentBuilder;
public static void main(String[] args) throws IOException {
Settings settings = ImmutableSettings.settingsBuilder()
.put("client.transport.sniff",true)
.put("cluster.name","elasticcluster").build();
Client client = new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress("[ipaddress]",9300));
XContentBuilder builder = null;
try {
builder = jsonBuilder().startObject().field("user", "testdata").field("postdata",new Date()).field("message","testmessage")
.endObject();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(builder.string());
IndexResponse response = client.prepareIndex("twitter","tweet","1").setSource(builder).execute().actionGet();
client.close();
}
you can also use a namedQuery named findAll for all your entities and call it in your generic FindAll with
entityManager.createNamedQuery(persistentClass.getSimpleName()+"findAll").getResultList();
Yes I know it is over half a year later and a tad late, BUT
row.names(df) <- NULL
does work. For me at least :-)
And if you have important information in row.names like dates for example, what I do is just :
df$Dates <- as.Date(row.names(df))
This will add a new column on the end but if you want it at the beginning of your data frame
df <- df[,c(7,1,2,3,4,5,6,...)]
Hope this helps those from Google :)
If someone like me want to do it with query builder in Laravel 5.2.23 it can be done like ->
$searchResultQuery = Users::query();
$searchResultQuery->where('status_message', '<>', '', 'and'); // is not null
$searchResultQuery->where('is_deleted', 'IS NULL', null, 'and'); // is null
Or with scope in model :
public function scopeNotNullOnly($query){
return $query->where('status_message', '<>', '');
}
In the following line.
temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();
You are calling First but the collection returned from db.Responses.Where is empty.
you should receive use page,like this
@Override
public Page<UserBoard> findLatestBoards() {
PageRequest request = new PageRequest(
0, PresentationUtil.PAGE_SIZE,
Sort.Direction.DESC, "boardId"
);
return boardRepository.findAll(request).getContent();
}
i also faced with this problem,you could solve it in 2 ways , as mentioned earlier use reflection to create the socket Second one is, client is looking for a server with given UUID and if your server isn't running parallel to client then this happens. Create a server with given client UUID and then listen and accept the client from server side.It will work.

Look at the traceback:
Traceback (most recent call last):
File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
out = iter(out)
TypeError: 'bool' object is not iterable
Your code isn't iterating the value, but the code receiving it is.
The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)
) or enclose it in a tuple ((False,)
).
Always read the traceback: it's correct, and it's helpful.
I know this is a Java question, but if you're using Kotlin you can do this quite nicely:
val uri = request.run {
if (queryString.isNullOrBlank()) requestURI else "$requestURI?$queryString"
}
Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.
I'm going to answer my own question.
Therefore, the following works for me
$qb->select('c')
->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
->where('c.username = :username');
or
$qb->select('c')
->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
->where('c.username = :username');
If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user
, picked from your example), then the syntax is quite simple:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('a.user', 'u')
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
Since you are applying a condition on the joined result here, using a LEFT JOIN
or simply JOIN
is the same.
If no association is available, then the query looks like following
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin(
'User\Entity\User',
'u',
\Doctrine\ORM\Query\Expr\Join::WITH,
'a.user = u.id'
)
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
This will produce a resultset that looks like following:
array(
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
// ...
)
For the same error in wamp/phpmyadmin
, I have edited my.ini
, commented the original :
;sql-mode= "STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER"
and added sql_mode = ""
.
I've found this issue to be prevalent in Entity Framework when we instantiate an Entity manually rather than through DBContext which will resolve all the Navigation Properties. If there are Foreign Key references (Navigation Properties) between tables and you use those references in your lambda (e.g. ProductDetail.Products.ID) then that "Products" context remains null if you manually created the Entity.
on button click, first open the database, fetch the data and close the data base like this
public class cytaty extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.galeria);
Button bLosuj = (Button) findViewById(R.id.button1);
bLosuj.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
myDatabaseHelper = new DatabaseHelper(cytaty.this);
myDatabaseHelper.openDataBase();
String text = myDatabaseHelper.getYourData(); //this is the method to query
myDatabaseHelper.close();
// set text to your TextView
}
});
}
}
and your getYourData()
in database class would be like this
public String[] getAppCategoryDetail() {
final String TABLE_NAME = "name of table";
String selectQuery = "SELECT * FROM " + TABLE_NAME;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
String[] data = null;
if (cursor.moveToFirst()) {
do {
// get the data into array, or class variable
} while (cursor.moveToNext());
}
cursor.close();
return data;
}
Did you try to specify resource only in context.xml
<Resource name="jdbc/PollDatasource" auth="Container" type="javax.sql.DataSource"
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby://localhost:1527/poll_database;create=true"
username="suhail" password="suhail"
maxActive="20" maxIdle="10" maxWait="-1" />
and remove <resource-ref>
section from web.xml
?
In one project I've seen configuration without <resource-ref>
section in web.xml
and it worked.
It's an educated guess, but I think <resource-ref>
declaration of JNDI
resource named jdbc/PollDatasource
in web.xml
may override declaration of resource with same name in context.xml
and the declaration in web.xml
is missing both driverClassName
and url
hence the NPEs for that properties.
I am using httpclient 4.4.
For solr query I used the following way and it worked.
NameValuePair nv2 = new BasicNameValuePair("fq","(active:true) AND (category:Fruit OR category1:Vegetable)");
nvPairList.add(nv2);
NameValuePair nv3 = new BasicNameValuePair("wt","json");
nvPairList.add(nv3);
NameValuePair nv4 = new BasicNameValuePair("start","0");
nvPairList.add(nv4);
NameValuePair nv5 = new BasicNameValuePair("rows","10");
nvPairList.add(nv5);
HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
URI uri = new URIBuilder(request.getURI()).addParameters(nvPairList).build();
request.setURI(uri);
HttpResponse response = client.execute(request);
if (response.getStatusLine().getStatusCode() != 200) {
}
BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
String output;
System.out.println("Output .... ");
String respStr = "";
while ((output = br.readLine()) != null) {
respStr = respStr + output;
System.out.println(output);
}
To count items after some number of items (offset), $qb->setFirstResults() cannot be applied in this case, as it works not as a condition of query, but as an offset of query result for a range of items selected (i. e. setFirstResult cannot be used togather with COUNT at all). So to count items, which are left I simply did the following:
//in repository class:
$count = $qb->select('count(p.id)')
->from('Products', 'p')
->getQuery()
->getSingleScalarResult();
return $count;
//in controller class:
$count = $this->em->getRepository('RepositoryBundle')->...
return $count-$offset;
Anybody knows more clean way to do it?
DataSet is collection of DataTables.... you can get the datatable from DataSet as below.
//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset
As @swanliu pointed out it is due to a bad connection.
However before adjusting the server timing and client timeout , I would first try and use a better connection pooling strategy.
Hibernate itself admits that its connection pooling strategy is minimal
Hibernate's own connection pooling algorithm is, however, quite rudimentary. It is intended to help you get started and is not intended for use in a production system, or even for performance testing. You should use a third party pool for best performance and stability. Just replace the hibernate.connection.pool_size property with connection pool specific settings. This will turn off Hibernate's internal pool. For example, you might like to use c3p0.
As stated in Reference : http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html
I personally use C3P0
. however there are other alternatives available including DBCP
.
Check out
Below is a minimal configuration of C3P0 used in my application:
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="c3p0.acquire_increment">1</property>
<property name="c3p0.idle_test_period">100</property> <!-- seconds -->
<property name="c3p0.max_size">100</property>
<property name="c3p0.max_statements">0</property>
<property name="c3p0.min_size">10</property>
<property name="c3p0.timeout">1800</property> <!-- seconds -->
By default, pools will never expire Connections. If you wish Connections to be expired over time in order to maintain "freshness", set maxIdleTime and/or maxConnectionAge. maxIdleTime defines how many seconds a Connection should be permitted to go unused before being culled from the pool. maxConnectionAge forces the pool to cull any Connections that were acquired from the database more than the set number of seconds in the past.
As stated in Reference : http://www.mchange.com/projects/c3p0/index.html#managing_pool_size
Edit:
I updated the configuration file (Reference), as I had just copy pasted the one for my project earlier.
The timeout should ideally solve the problem, If that doesn't work for you there is an expensive solution which I think you could have a look at:
Create a file “c3p0.properties” which must be in the root of the classpath (i.e. no way to override it for particular parts of the application). (Reference)
# c3p0.properties
c3p0.testConnectionOnCheckout=true
With this configuration each connection is tested before being used. It however might affect the performance of the site.
Just open your repository file and add this new function, then call it inside your controller:
public function distinctCategories(){
return $this->createQueryBuilder('cc')
->where('cc.contenttype = :type')
->setParameter('type', 'blogarticle')
->groupBy('cc.blogarticle')
->getQuery()
->getResult()
;
}
Then within your controller:
public function index(YourRepository $repo)
{
$distinctCategories = $repo->distinctCategories();
return $this->render('your_twig_file.html.twig', [
'distinctCategories' => $distinctCategories
]);
}
Good luck!
Yep, make Stored proc parameter as VARCHAR(...)
And then pass comma separated values to a stored procedure.
If you are using Sql Server 2008 you can leverage TVP (Table Value Parameters): SQL 2008 TVP and LINQ if structure of QueryTable more complex than array of strings otherwise it would be an overkill because requires table type to be created within SQl Server
I just put SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
as first line of my Job.execute(JobExecutionContext context)
method.
As the other answers state there is no way getting query string parameters using servlet api.
So, I think the best way to get query parameters is parsing the query string yourself. ( It is more complicated iterating over parameters and checking if query string contains the parameter)
I wrote below code to get query string parameters. Using apache StringUtils and ArrayUtils which supports CSV separated query param values as well.
Example: username=james&username=smith&password=pwd1,pwd2
will return
password : [pwd1, pwd2]
(length = 2)
username : [james, smith]
(length = 2)
public static Map<String, String[]> getQueryParameters(HttpServletRequest request) throws UnsupportedEncodingException {
Map<String, String[]> queryParameters = new HashMap<>();
String queryString = request.getQueryString();
if (StringUtils.isNotEmpty(queryString)) {
queryString = URLDecoder.decode(queryString, StandardCharsets.UTF_8.toString());
String[] parameters = queryString.split("&");
for (String parameter : parameters) {
String[] keyValuePair = parameter.split("=");
String[] values = queryParameters.get(keyValuePair[0]);
//length is one if no value is available.
values = keyValuePair.length == 1 ? ArrayUtils.add(values, "") :
ArrayUtils.addAll(values, keyValuePair[1].split(",")); //handles CSV separated query param values.
queryParameters.put(keyValuePair[0], values);
}
}
return queryParameters;
}
I know this is old, but i stumbled on it with Google.
If you have a return value in your stored procedure say "Return 1" - not using output parameters.
You can do the following - "@RETURN_VALUE" is silently added to every command object. NO NEED TO EXPLICITLY ADD
cmd.ExecuteNonQuery();
rtn = (int)cmd.Parameters["@RETURN_VALUE"].Value;
In my case, using Include()
solved this error and depending on the situation can be a lot more efficient then issuing multiple queries when it can all be queried at once with a join.
IEnumerable<User> users = db.Users.Include("Projects.Tasks.Messages");
foreach (User user in users)
{
Console.WriteLine(user.Name);
foreach (Project project in user.Projects)
{
Console.WriteLine("\t"+project.Name);
foreach (Task task in project.Tasks)
{
Console.WriteLine("\t\t" + task.Subject);
foreach (Message message in task.Messages)
{
Console.WriteLine("\t\t\t" + message.Text);
}
}
}
}
->where($qb->expr()->in('foo.bar', ':data'))
->setParameter('participants', $data);
Also works with:
->andWhere($qb->expr()->in('foo.bar', ':users'))
->setParameter('data', $data);

This might not be related answer, but this link Detecting and fixing circular references in JavaScript might helpful to detect objects which are causing circular dependency.
I think you need to use Expr
with ->set()
(However THIS IS NOT SAFE and you shouldn't do it):
$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
->set('u.username', $qb->expr()->literal($username))
->set('u.email', $qb->expr()->literal($email))
->where('u.id = ?1')
->setParameter(1, $editId)
->getQuery();
$p = $q->execute();
It's much safer to make all your values parameters instead:
$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
->set('u.username', '?1')
->set('u.email', '?2')
->where('u.id = ?3')
->setParameter(1, $username)
->setParameter(2, $email)
->setParameter(3, $editId)
->getQuery();
$p = $q->execute();
Wouldn't you just change:
numero = stmt.executeUpdate(query);
to:
numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);
Take a look at the documentation for the JDBC Statement
interface.
Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero
variable is completely irrelevant and its value is never read after it is set.
Why are you using WMI? Can't you use the standard .NET functionality?
System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
This occurs when you specify the different name for repository table name and database table name. Please check your table name with database and repository.
This is due to the mismatch of the data type of your java Entity and the database table column. Please review if all the column is exact same data type as your entity. This mismatch happens when we update our model attribute's data-type.
Just found out the hard way that it is
SELECT 1 FROM DUAL
for MaxDB as well.
I'm not Reputable enough to upvote or comment yet, but LukeH's answer was spot on for me.
As AES encryption is the standard to use now, it produces a base64 string (at least all the encrypt/decrypt implementations I've seen). This string has a length in multiples of 4 (string.length % 4 = 0)
The strings I was getting contained + and = on the beginning or end, and when you just concatenate that into a URL's querystring, it will look right (for instance, in an email you generate), but when the the link is followed and the .NET page recieves it and puts it into this.Page.Request.QueryString, those special characters will be gone and your string length will not be in a multiple of 4.
As the are special characters at the FRONT of the string (ex: +), as well as = at the end, you can't just add some = to make up the difference as you are altering the cypher text in a way that doesn't match what was actually in the original querystring.
So, wrapping the cypher text with HttpUtility.URLEncode (not HtmlEncode) transforms the non-alphanumeric characters in a way that ensures .NET parses them back into their original state when it is intepreted into the querystring collection.
The good thing is, we only need to do the URLEncode when generating the querystring for the URL. On the incoming side, it's automatically translated back into the original string value.
Here's some example code
string cryptostring = MyAESEncrypt(MySecretString);
string URL = WebFunctions.ToAbsoluteUrl("~/ResetPassword.aspx?RPC=" + HttpUtility.UrlEncode(cryptostring));
Request.QueryString
helps you to get the parameters
and values included within the URL
example
string http = "http://dave.com/customers.aspx?customername=dave"
string customername = Request.QueryString["customername"].ToString();
so the customername variable should be equal to dave
regards

public static bool TryGetQueryString<T>(string key, out T queryString)
On Android, you can use the Uri.parse static method of the android.net.Uri class to do the heavy lifting. If you're doing anything with URIs and Intents you'll want to use it anyways.
I had this problem and like Anderson Imes said it had to do with app settings. My problem was the scope of one of my settings was set to "User" when it should have been "Application".
2 artlung's answer: It works with second line only in my code (IE7, IE8; Jquery v1.6):
var input = $('#some_elem');
input.focus().val(input.val());
Addition: if input element was added to DOM using JQuery, a focus is not set in IE. I used a little trick:
input.blur().focus().val(input.val());
I use CodeIgniter. One server OK ... this one probably older ... Anyway using
$this->db->reconnect();
Fixed it.
tell you the true, I still don't get what you need, but
window.location(url);
should be
window.location = url;
a search on window.location reference will tell you that.
You just need to add a jquery selector after the url.
See: http://api.jquery.com/load/
Example straight from the API:
$('#result').load('ajax/test.html #container');
So what that does is it loads the #container element from the specified url.

A more up to date answer for anyone else who comes across this:
(from https://www.jetbrains.com/help/idea/eclipse.html, §Auto-compilation; click for screenshots)
Compile automatically:
To enable automatic compilation, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler and select the Build project automatically option
Show all errors in one place:
The Problems tool window appears if the Make project automatically option is enabled in the Compiler settings. It shows a list of problems that were detected on project compilation.
Use the Eclipse compiler: This is actually bundled in IntelliJ. It gives much more useful error messages, in my opinion, and, according to this blog, it's much faster since it was designed to run in the background of an IDE and uses incremental compilation.
While Eclipse uses its own compiler, IntelliJ IDEA uses the javac compiler bundled with the project JDK. If you must use the Eclipse compiler, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler | Java Compiler and select it... The biggest difference between the Eclipse and javac compilers is that the Eclipse compiler is more tolerant to errors, and sometimes lets you run code that doesn't compile.
Actually there are 3 places where gradle.properties
can be placed:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradlemyProject2
in your case)myProject
)Gradle looks for gradle.properties
in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).
You can find more details about it in gradle documentation here.
If you use the Oracle native data provider rather than the Microsoft driver then you can get at all field types
Dim cn As New Oracle.DataAccess.Client.OracleConnection
Dim cm As New Oracle.DataAccess.Client.OracleCommand
Dim dr As Oracle.DataAccess.Client.OracleDataReader
The connection string does not require a Provider value so you would use something like:
"Data Source=myOracle;UserID=Me;Password=secret"
Open the connection:
cn.ConnectionString = "Data Source=myOracle;UserID=Me;Password=secret"
cn.Open()
Attach the command and set the Sql statement
cm.Connection = cn
cm.CommandText = strCommand
Set the Fetch size. I use 4000 because it's as big as a varchar can be
cm.InitialLONGFetchSize = 4000
Start the reader and loop through the records/columns
dr = cm.ExecuteReader
Do while dr.read()
strMyLongString = dr(i)
Loop
You can be more specific with the read, eg dr.GetOracleString(i) dr.GetOracleClob(i) etc. if you first identify the data type in the column. If you're reading a LONG datatype then the simple dr(i)
or dr.GetOracleString(i)
works fine. The key is to ensure that the InitialLONGFetchSize is big enough for the datatype. Note also that the native driver does not support CommandBehavior.SequentialAccess
for the data reader but you don't need it and also, the LONG field does not even have to be the last field in the select statement.
The thing here is that you're using a for loop outside of your conditional statement.
After the conditions in your IF statement are met you probably navigate to another page, thus when the for loop attempts to iterate once more, you get the stale element error because you're on a different page.
You can add a break at the end of your if statement, this worked for me.
There is a much simpler way. Put your picture in a comment box within the description cell. That way you only have one column and when you sort the picture will always stay with the description. Okay... Right click the cell containing the description... Insert comment...right click the outer border... Format comment...colours and lines tab... Colour drop down...Fill effects...Picture tab...select picture...browse for your picture (it might be best to keep all pictures in one folder for ease of placement)...ok... you will probably need to go to the size tab and frig around with the height and width. Done... You now only need to mouse over the red in the top right corner of the cell and the picture will appear...like magic.
This method means that the row height can be kept to a minimum and the pictures can be as big as you like.

You are trying to call DeckOfCards::shuffle
with a deckOfCards
parameter:
deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck
But the method takes a vector<Card>&
:
void deckOfCards::shuffle(vector<Card>& deck)
The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.
Error:
[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'
Paraphrased:
Hey, pal. You're trying to call a function called
shuffle
which apparently takes a single parameter of type reference-to-deckOfCards
, but there is no such function.
Error:
[Note] candidate is:
In file included from main.cpp
[Note] void deckOfCards::shuffle(std::vector&)
Paraphrased:
I mean, maybe you meant this other function called
shuffle
, but that one takes a reference-tovector<something>
.
Error:
[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'
Which I'd be happy to call if I knew how to convert from a
deckOfCards
to avector
; but I don't. So I won't.
If you are using firestore (and not just storing the timestamp as a string) a date field in a document will return a Timestamp. The Timestamp object contains a toDate()
method.
Using timeago you can create a relative time quite simply:
_ago(Timestamp t) {
return timeago.format(t.toDate(), 'en_short');
}
build() {
return Text(_ago(document['mytimestamp'])));
}
Make sure to set _firestore.settings(timestampsInSnapshotsEnabled: true);
to return a Timestamp instead of a Date object.
Yes. You can use rgba in both webkit and moz gradient declarations:
/* webkit example */
background-image: -webkit-gradient(
linear, left top, left bottom, from(rgba(50,50,50,0.8)),
to(rgba(80,80,80,0.2)), color-stop(.5,#333333)
);
(src)
/* mozilla example - FF3.6+ */
background-image: -moz-linear-gradient(
rgba(255, 255, 255, 0.7) 0%, rgba(255, 255, 255, 0) 95%
);
(src)
Apparently you can even do this in IE, using an odd "extended hex" syntax. The first pair (in the example 55) refers to the level of opacity:
/* approximately a 33% opacity on blue */
filter: progid:DXImageTransform.Microsoft.gradient(
startColorstr=#550000FF, endColorstr=#550000FF
);
/* IE8 uses -ms-filter for whatever reason... */
-ms-filter: progid:DXImageTransform.Microsoft.gradient(
startColorstr=#550000FF, endColorstr=#550000FF
);
(src)
The difference is that one (forms time-out) has to do authenticating the user and the other( session timeout) has to do with how long cached data is stored on the server. So they are very independent things so one doesn't take precedence over the other.
So many good answers already. Backbone js helps to keep the code organised. Changing the model/collection takes care of the view rendering automaticallty which reduces lot of development overhead.
Even though it provides maximum flexibility for development, developers should be careful to destroy the models and remove the views properly. Otherwise there may be memory leak in the application.
This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:
This worked for me
$("div").css({"left":"2000px"}).animate({"left":"0px"}, "slow");
This is what I came up with using only jQuery. It's just a matter of putting the pieces together.
//Gather date information from local system
var ThisMonth = new Date().getMonth() + 1;
var ThisDay = new Date().getDate();
var ThisYear = new Date().getFullYear();
var ThisDate = ThisMonth.toString() + "/" + ThisDay.toString() + "/" + ThisYear.toString();
//Gather time information from local system
var ThisHour = new Date().getHours();
var ThisMinute = new Date().getMinutes();
var ThisTime = ThisHour.toString() + ":" + ThisMinute.toString();
//Concatenate date and time for date-time stamp
var ThisDateTime = ThisDate + " " + ThisTime;
This is a very informal answer to the question asked.
Can 3233 be written as the product of two other numbers bigger than 1? Is there any way to walk a path around all of the Seven Bridges of Königsberg without taking any bridge twice? These are examples of questions that share a common trait. It may not be obvious how to efficiently determine the answer, but if the answer is 'yes', then there's a short and quick to check proof. In the first case a non-trivial factorization of 51; in the second, a route for walking the bridges (fitting the constraints).
A decision problem is a collection of questions with yes or no answers that vary only in one parameter. Say the problem COMPOSITE={"Is n
composite": n
is an integer} or EULERPATH={"Does the graph G
have an Euler path?": G
is a finite graph}.
Now, some decision problems lend themselves to efficient, if not obvious algorithms. Euler discovered an efficient algorithm for problems like the "Seven Bridges of Königsberg" over 250 years ago.
On the other hand, for many decision problems, it's not obvious how to get the answer -- but if you know some additional piece of information, it's obvious how to go about proving you've got the answer right. COMPOSITE is like this: Trial division is the obvious algorithm, and it's slow: to factor a 10 digit number, you have to try something like 100,000 possible divisors. But if, for example, somebody told you that 61 is a divisor of 3233, simple long division is a efficient way to see that they're correct.
The complexity class NP is the class of decision problems where the 'yes' answers have short to state, quick to check proofs. Like COMPOSITE. One important point is that this definition doesn't say anything about how hard the problem is. If you have a correct, efficient way to solve a decision problem, just writing down the steps in the solution is proof enough.
Algorithms research continues, and new clever algorithms are created all the time. A problem you might not know how to solve efficiently today may turn out to have an efficient (if not obvious) solution tomorrow. In fact, it took researchers until 2002 to find an efficient solution to COMPOSITE! With all these advances, one really has to wonder: Is this bit about having short proofs just an illusion? Maybe every decision problem that lends itself to efficient proofs has an efficient solution? Nobody knows.
Perhaps the biggest contribution to this field came with the discovery a peculiar class of NP problems. By playing around with circuit models for computation, Stephen Cook found a decision problem of the NP variety that was provably as hard or harder than every other NP problem. An efficient solution for the boolean satisfiability problem could be used to create an efficient solution to any other problem in NP. Soon after, Richard Karp showed that a number of other decision problems could serve the same purpose. These problems, in a sense the "hardest" problems in NP, became known as NP-complete problems.
Of course, NP is only a class of decision problems. Many problems aren't naturally stated in this manner: "find the factors of N", "find the shortest path in the graph G that visits every vertex", "give a set of variable assignments that makes the following boolean expression true". Though one may informally talk about some such problems being "in NP", technically that doesn't make much sense -- they're not decision problems. Some of these problems might even have the same sort of power as an NP-complete problem: an efficient solution to these (non-decision) problems would lead directly to an efficient solution to any NP problem. A problem like this is called NP-hard.
You can use Smartface for developing your app with javascript and deploy to stores directly without a Mac. What they say is below.
With the Cloud Build module, Smartface removes all the hassle of application deployment. You don’t need to worry about managing code signing certificates and having a Mac to sign your apps. Smartface Cloud can store all your iOS certificates and Android keystores in one place and signing and building is fully in the cloud. No matter which operating system you use, you can get store-ready (or enterprise distribution) binaries. Smartface frees you from the lock-in to Mac and allows you to use your favorite operating system for development.
SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS
(SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)
or
SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN
(SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)
or
SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B
ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL
Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.
I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

Using d.Keys()(i)
method is a very bad idea, because on each call it will re-create a new array (you will have significant speed reduction).
Here is an analogue of Scripting.Dictionary

Dim oDict As clsTrickHashTable
Sub aaa()
Set oDict = New clsTrickHashTable
oDict.Add "a", "aaa"
oDict.Add "b", "bbb"
For i = 0 To oDict.Count - 1
Debug.Print oDict.Keys(i) & " - " & oDict.Items(i)
Next

I tend to follow the pseudo-conventions established by Java Core/Sun, e.g. in the Collections classes:
List
- interface for the "conceptual" objectArrayList
- concrete implementation of interfaceLinkedList
- concrete implementation of interfaceAbstractList
- abstract "partial" implementation to assist custom implementationsI used to do the same thing modeling my event classes after the AWT Event/Listener/Adapter paradigm.
No, I don't think there is. Unfortunately, you're stuck calling getApplicationContext()
from Activity
or one of the other subclasses of Context
. Also, this question is somewhat related.
struct emp {
int id;
char *name;
};
struct emp get() {
char *name = "John";
struct emp e1 = {100, name};
return (e1);
}
int main() {
struct emp e2 = get();
printf("%s\n", e2.name);
}
works fine with newer versions of compilers. Just like id, content of the name gets copied to the assigned structure variable.
The problem here is much more complex than removing the container padding since the grid structure relies on this padding when applying negative margins for the enclosed rows.
Removing the container padding in this case will cause an x-axis overflow caused by all the rows inside of this container class, this is one of the most stupid things about the Bootstrap Grid.
Logically it should be approached by
.container
class for anything other than rows.container
class that has no padding for use with non-grid html.container
padding on mobile you can manually remove it with media queries then overflow-x: hidden;
which is not very reliable but works in most cases.If you are using LESS
the end result will look like this
@media (max-width: @screen-md-max) {
.container{
padding: 0;
overflow-x: hidden;
}
}
Change the media query to whatever size you want to target.
Final thoughts, I would highly recommend using the Foundation Framework
Grid as its way more advanced
It can be done in a single command. You need to set the IDENTITY property for "auto number":
ALTER TABLE MyTable ADD mytableID int NOT NULL IDENTITY (1,1) PRIMARY KEY

CONSTRAINT PK_MyTable PRIMARY KEY CLUSTERED (MyTableID)

See Documentation
The static import declaration is analogous to the normal import declaration. Where the normal import declaration imports classes from packages, allowing them to be used without package qualification, the static import declaration imports static members from classes, allowing them to be used without class qualification.
So when should you use static import? Very sparingly! Only use it when you'd otherwise be tempted to declare local copies of constants, or to abuse inheritance (the Constant Interface Antipattern). In other words, use it when you require frequent access to static members from one or two classes. If you overuse the static import feature, it can make your program unreadable and unmaintainable, polluting its namespace with all the static members you import. Readers of your code (including you, a few months after you wrote it) will not know which class a static member comes from. Importing all of the static members from a class can be particularly harmful to readability; if you need only one or two members, import them individually. Used appropriately, static import can make your program more readable, by removing the boilerplate of repetition of class names.
In Visual Studio 2013, I couldn't get "Include in Project" to work when right-clicking on a folder. What did work is expanding the folder, selecting all the files then choosing "Include in Project". It was quite tedious as you have to do each folder one by one (but at least you can do all files in each folder in one go), and it appears to store the file path (you can see this by viewing properties on the file and looking at the "Relative Path" option.)
I am hoping to use this to deploy some data files in a Visual Studio Installer project, and it seems to pick up the included files and preserve their paths.

For Evergreen browsers, this will build a staircase based on an incoming character and the number of stairs to build.
function StairCase(character, input) {
let i = 0;

const hashes = character.repeat(i + 1);
console.log(spaces + hashes);
i++;
}
}
//Implement

}
var str = '' + this;
count = +count;
if (count != count) {
count = 0;

if (count < 0) {
throw new RangeError('repeat count must be non-negative');
}
if (count == Infinity) {
throw new RangeError('repeat count must be less than infinity');
}
count = Math.floor(count);
if (str.length == 0 || count == 0) {
return '';
}
// Ensuring count is a 31-bit integer allows us to heavily optimize the
// main part. But anyway, most current (August 2014) browsers can't handle

if (str.length * count >= 1 << 28) {
throw new RangeError('repeat count must not overflow maximum string size');
}
var rpt = '';
for (;;) {
if ((count & 1) == 1) {
rpt += str;
}
count >>>= 1;

}
// Could we try:
// return Array(count + 1).join(this);
return rpt;
}
}
There are a few things interacting here:
docker run your_image arg1 arg2
will replace the value of CMD
with arg1 arg2
. That's a full replacement of the CMD, not appending more values to it. This is why you often see docker run some_image /bin/bash
to run a bash shell in the container.
When you have both an ENTRYPOINT and a CMD value defined, docker starts the container by concatenating the two and running that concatenated command. So if you define your entrypoint to be file.sh
, you can now run the container with additional args that will be passed as args to file.sh
.
Entrypoints and Commands in docker have two syntaxes, a string syntax that will launch a shell, and a json syntax that will perform an exec. The shell is useful to handle things like IO redirection, chaining multiple commands together (with things like &&
), variable substitution, etc. However, that shell gets in the way with signal handling (if you've ever seen a 10 second delay to stop a container, this is often the cause) and with concatenating an entrypoint and command together. If you define your entrypoint as a string, it would run /bin/sh -c "file.sh"
, which alone is fine. But if you have a command defined as a string too, you'll see something like /bin/sh -c "file.sh" /bin/sh -c "arg1 arg2"
as the command being launched inside your container, not so good. See the table here for more on how these two options interact
The shell -c
option only takes a single argument. Everything after that would get passed as $1
, $2
, etc, to that single argument, but not into an embedded shell script unless you explicitly passed the args. I.e. /bin/sh -c "file.sh $1 $2" "arg1" "arg2"
would work, but /bin/sh -c "file.sh" "arg1" "arg2"
would not since file.sh
would be called with no args.
Putting that all together, the common design is:
FROM ubuntu:14.04
COPY ./file.sh /
RUN chmod 755 /file.sh
# Note the json syntax on this next line is strict, double quotes, and any syntax
# error will result in a shell being used to run the line.
ENTRYPOINT ["file.sh"]
And you then run that with:
docker run your_image arg1 arg2
There's a fair bit more detail on this at:

Integer.toHexString(color.getGreen()).toUpperCase() + (color.getGreen() < 16 ? 0 : "") +
Integer.toHexString(color.getBlue()).toUpperCase() + (color.getBlue() < 16 ? 0 : "");
}
I think that this wil work.
Another option is to use placeholders.
Html:
<body>
<div id="root">
<asp:PlaceHolder ID="iframeDiv" runat="server"/>
</div>
</body>
C#:
iframeDiv.Controls.Add(new LiteralControl("<iframe src=\"" + whatever.com + "\"></iframe><br />"));
str.charCodeAt(index)
Using charCodeAt()
The following example returns 65, the Unicode value for A
.
'ABC'.charCodeAt(0)
// returns 65

www.mybank.com
mybank.com
will result in a request of (conceptually) the form http://www.mybank.com/transfer?to=<SomeAccountnumber>;amount=<SomeAmount>
. (Your account number is not needed, because it is implied by your login.)www.cute-cat-pictures.org
, not knowing that it is a malicious site.mybank.com
(requires some luck!), they could include on their page a request like http://www.mybank.com/transfer?to=123456;amount=10000
(where 123456
is the number of their Cayman Islands account and 10000
is an amount that you previously thought you were glad to possess).www.cute-cat-pictures.org
page, so your browser will make that request.www.mybank.com
cookie and it will look perfectly legitimate. There goes your money!This is the world without CSRF tokens.
Now for the better one with CSRF tokens:
http://www.mybank.com/transfer?to=123456;amount=10000;token=31415926535897932384626433832795028841971
. mybank.com
will include on their own web page when they serve it to you. It is different each time they serve any page to anybody.www.mybank.com
.Result: You keep your 10000
monetary units. I suggest you donate some of that to Wikipedia.
(Your mileage may vary.)
EDIT from comment worth reading:
It would be worthy to note that script from www.cute-cat-pictures.org
normally does not have access to your anti-CSRF token from www.mybank.com
because of HTTP access control. This note is important for some people who unreasonably send a header Access-Control-Allow-Origin: *
for every website response without knowing what it is for, just because they can't use the API from another website.
Although answers here are sufficient, I really think W3Schools example on this issue is very straightforward (it cleared up the confusion (for me) right away).
Use the
:hover
selector to change the style of a button when you move the mouse over it.Tip: Use the transition-duration property to determine the speed of the "hover" effect:
Example
.button { -webkit-transition-duration: 0.4s; /* Safari & Chrome */ transition-duration: 0.4s; } .button:hover { background-color: #4CAF50; /* Green */ color: white; }
In summary, for transitions where you want the "enter" and "exit" animations to be the same, you need to employ transitions on the main selector .button
rather than the hover selector .button:hover
. For transitions where you want the "enter" and "exit" animations to be different, you will need specify different main selector and hover selector transitions.
I use this method to add a border outside the image. You can customise the border width in boderWidth
constant.
func addBorderToImage(image : UIImage) -> UIImage {
let bgImage = image.cgImage
let initialWidth = (bgImage?.width)!
let initialHeight = (bgImage?.height)!
let borderWidth = Int(Double(initialWidth) * 0.10);
let width = initialWidth + borderWidth * 2
let height = initialHeight + borderWidth * 2
let data = malloc(width * height * 4)
let context = CGContext(data: data,
width: width,
height: height,
bitsPerComponent: 8,
bytesPerRow: width * 4,
space: (bgImage?.colorSpace)!,
bitmapInfo: CGImageAlphaInfo.premultipliedLast.rawValue);
context?.draw(bgImage!, in: CGRect(x: CGFloat(borderWidth), y: CGFloat(borderWidth), width: CGFloat(initialWidth), height: CGFloat(initialHeight)))
context?.setStrokeColor(UIColor.white.cgColor)
context?.setLineWidth(CGFloat(borderWidth))
context?.move(to: CGPoint(x: 0, y: 0))
context?.addLine(to: CGPoint(x: 0, y: height))
context?.addLine(to: CGPoint(x: width, y: height))
context?.addLine(to: CGPoint(x: width, y: 0))
context?.addLine(to: CGPoint(x: 0, y: 0))
context?.strokePath()
let cgImage = context?.makeImage()
let uiImage = UIImage(cgImage: cgImage!)
free(data)
return uiImage;
}
Another useful property of the cross product is that its magnitude is related to the sine of the angle between the two vectors:
| a x b | = |a| . |b| . sine(theta)
or
sine(theta) = | a x b | / (|a| . |b|)
So, in implementation 1 above, if a
and b
are known in advance to be unit vectors then the result of that function is exactly that sine() value.
char (with a lower-case c) is a numeric type. It already holds the ascii value of the char. Just cast it to an integer to display it as a numeric value rather than a textual value:
System.out.println("char " + ch + " has the following value : " + (int) ch);
"Make browser window blink in task Bar"
via Javascript
is not possible!!
We can use append
append(l1, l2)
It also has arguments to insert element at a particular location.
This will end the function, and you can even customize the "Error" message:
import sys
def end():
if condition:
# the player wants to play again:
main()
elif not condition:
sys.exit("The player doesn't want to play again") #Right here
Given a floating point value, we can round it trivially with printf:
# round $1 to $2 decimal places
round() {
printf "%.{$2:-0}f" "$1"
}
Then,
# do some math, bc style
math() {
echo "$*" | bc -l
}
$ echo "Pi, to five decimal places, is $(round $(math "4*a(1)") 5)"
Pi, to five decimal places, is 3.14159
Or, to use the original request:
$ echo "3/2, rounded to the nearest integer, is $(round $(math "3/2") 0)"
3/2, rounded to the nearest integer, is 2
Laravel - htmlspecialchars() expects parameter 1 to be string, object given.
thank me latter.........................
when you send or get array from contrller or function but try to print as single value or single variable in laravel blade file so it throws an error
->use any think who convert array into string it work.
solution: 1)run the foreach loop and get single single value and print. 2)The implode() function returns a string from the elements of an array. {{ implode($your_variable,',') }}
implode is best way to do it and its 100% work.
Using a Messenger is another simple way to communicate between a Service and an Activity.
In the Activity, create a Handler with a corresponding Messenger. This will handle messages from your Service.
class ResponseHandler extends Handler {
@Override public void handleMessage(Message message) {
Toast.makeText(this, "message from service",
Toast.LENGTH_SHORT).show();
}
}
Messenger messenger = new Messenger(new ResponseHandler());
The Messenger can be passed to the service by attaching it to a Message:
Message message = Message.obtain(null, MyService.ADD_RESPONSE_HANDLER);
message.replyTo = messenger;
try {
myService.send(message);
catch (RemoteException e) {
e.printStackTrace();
}
A full example can be found in the API demos: MessengerService and MessengerServiceActivity. Refer to the full example for how MyService works.
Extended Chris Pickett's answer because in my case I needed to search deeper than one attribute level:
function findWithAttr(array, attr, value) {
if (attr.indexOf('.') >= 0) {
var split = attr.split('.');
var attr1 = split[0];
var attr2 = split[1];
for(var i = 0; i < array.length; i += 1) {
if(array[i][attr1][attr2] === value) {
return i;
}
}
} else {
for(var i = 0; i < array.length; i += 1) {
if(array[i][attr] === value) {
return i;
}
}
};
};
You can pass 'attr1.attr2' into the function
Internally, .bind
maps directly to .on
in the current version of jQuery. (The same goes for .live
.) So there is a tiny but practically insignificant performance hit if you use .bind
instead.
However, .bind
may be removed from future versions at any time. There is no reason to keep using .bind
and every reason to prefer .on
instead.
let total = 0;
for (let value of [1,2,3,4]) {
total += value;
}
I think this would do it:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".divlink").click(function(){
$("#content").attr("src" , $(this).attr("ref"));
});
});
</script>
</head>
<body>
<iframe id="content"></iframe>
<a href="#" ref="page1.html" class="divlink" >Page 1</a><br />
<a href="#" ref="page2.html" class="divlink" >Page 2</a><br />
<a href="#" ref="page3.html" class="divlink" >Page 3</a><br />
<a href="#" ref="page4.html" class="divlink" >Page 4</a><br />
<a href="#" ref="page5.html" class="divlink" >Page 5</a><br />
<a href="#" ref="page6.html" class="divlink" >Page 6</a><br />
</body>
</html>
By the way if you can avoid Jquery, you can just use the target
attribute of <a>
element:
<html>
<body>
<iframe id="content" name="content"></iframe>
<a href="page1.html" target="content" >Page 1</a><br />
<a href="page2.html" target="content" >Page 2</a><br />
<a href="page3.html" target="content" >Page 3</a><br />
<a href="page4.html" target="content" >Page 4</a><br />
<a href="page5.html" target="content" >Page 5</a><br />
<a href="page6.html" target="content" >Page 6</a><br />
</body>
</html>
The simplest way is using the Multiplicative formula. It works for (n,n) and (n,0) as expected.
def coefficient(n,k):
c = 1.0
for i in range(1, k+1):
c *= float((n+1-i))/float(i)
return c

Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.
path.join
returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.
For instance:
path.join('app/libs/oauth', '/../ssl')
resolves to app/libs/ssl
path.resolve
, on the other hand, will resolve to an absolute path.
For instance, when you run:
path.resolve('bar', '/foo');
The path returned will be /foo
since that is the first absolute path that can be constructed.
However, if you run:
path.resolve('/bar/bae', '/foo', 'test');
The path returned will be /foo/test
again because that is the first absolute path that can be formed from right to left.
If you don't provide a path that specifies the root directory then the paths given to the resolve
function are appended to the current working directory. So if your working directory was /home/mark/project/
:
path.resolve('test', 'directory', '../back');
resolves to
/home/mark/project/test/back
Using __dirname
is the absolute path to the directory containing the source file. When you use path.resolve
or path.join
they will return the same result if you give the same path following __dirname
. In such cases it's really just a matter of preference.
It is clear that tvi.header
is not a String
. The ==
is an operator that is overloaded by String
class, which means it will be working only if compiler knows that both side of the operator are String
.

Every node.js process is single threaded by design. Therefore to get multiple threads, you have to have multiple processes (As some other posters have pointed out, there are also libraries you can link to that will give you the ability to work with threads in Node, but no such capability exists without those libraries. See answer by Shawn Vincent referencing https://github.com/audreyt/node-webworker-threads)
You can start child processes from your main process as shown here in the node.js documentation: http://nodejs.org/api/child_process.html. The examples are pretty good on this page and are pretty straight forward.
Your parent process can then watch for the close event on any process it started and then could force close the other processes you started to achieve the type of one fail all stop strategy you are talking about.
Also see: Node.js on multi-core machines
Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.
$("legend").each(function() {
var SoftwareItem = $(this).text();
itemCost = GetItemCost(SoftwareItem);
$("input:checked").each(function() {
var Component = $(this).next("label").text();
itemCost += GetItemCost(Component);
});
$(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
});
How about this:
import sys
def testPyVer(reqver):
if float(sys.version[:3]) >= reqver:
return 1
else:
return 0
#blah blah blah, more code
if testPyVer(3.0) == 1:
#do stuff
else:
#print python requirement, exit statement
In your action method, return Json(object) to return JSON to your page.
public ActionResult SomeActionMethod() {
return Json(new {foo="bar", baz="Blech"});
}
Then just call the action method using Ajax. You could use one of the helper methods from the ViewPage such as
<%= Ajax.ActionLink("SomeActionMethod", new AjaxOptions {OnSuccess="somemethod"}) %>
SomeMethod would be a javascript method that then evaluates the Json object returned.
If you want to return a plain string, you can just use the ContentResult:
public ActionResult SomeActionMethod() {
return Content("hello world!");
}
ContentResult by default returns a text/plain as its contentType.
This is overloadable so you can also do:
return Content("<xml>This is poorly formatted xml.</xml>", "text/xml");
Open httpd.conf file in your text editor. Find this line:
Listen 80
and change it
Listen 8079
After change, save it and restart apache.
There is no Wi-Fi Direct type of connection available. The primary issue being that Apple does not allow programmatic setting of the Wi-Fi network SSID and password. However, this improves substantially in iOS 11 where you can at least prompt the user to switch to another WiFi network.
QA1942 - iOS Wi-Fi Management APIs
This technology is useful if you want to provide a list of Wi-Fi networks that a user might want to connect to in a manager type app. It requires that you apply for this entitlement with Apple and the email address is in the documentation.
These technologies allow the accessory connect to the same network as the iPhone and are not for setting up a peer-to-peer connection.
These APIs come close to what you want, but they're Apple-to-Apple only.
Brought up at WWDC 2017 Advances in Networking, Part 1 is NEHotspotConfiguration which allows the app to specify and prompt to connect to a specific network.
Another way (to aid @NullUserException and @Wexoni's comments) is to retrieve the object's index in the array and then go from there:
var index = array.map(function(obj){ return obj.name; }).indexOf('name-I-am-looking-for');
// Then we can access it to do whatever we want
array[index] = {name: 'newName', value: 'that', other: 'rocks'};
find supports wildcard matches, just add a *
:
find / -type d -name "ora10*"
Dim text As String = "123.45"
Dim value As Double
If Double.TryParse(text, value) Then
' text is convertible to Double, and value contains the Double value now
Else
' Cannot convert text to Double
End If
This appears to be a variable naming convention in Node.js control-flow code, where a reference to the next function to execute is given to a callback for it to kick-off when it's done.
See, for example, the code samples here:
Let's look at the example you posted:
function loadUser(req, res, next) {
if (req.session.user_id) {
User.findById(req.session.user_id, function(user) {
if (user) {
req.currentUser = user;
return next();
} else {
res.redirect('/sessions/new');
}
});
} else {
res.redirect('/sessions/new');
}
}
app.get('/documents.:format?', loadUser, function(req, res) {
// ...
});
The loadUser
function expects a function in its third argument, which is bound to the name next
. This is a normal function parameter. It holds a reference to the next action to perform and is called once loadUser
is done (unless a user could not be found).
There's nothing special about the name next
in this example; we could have named it anything.
Note that when you say:
bool (*a)();
you are declaring a
of type "pointer to function returning bool
and taking an unspecified number of parameters". Assuming bool
is defined (maybe you're using C99 and have included stdbool.h
, or it may be a typedef), this may or may not be what you want.
The problem here is that there is no way for the compiler to now check if a
is assigned to a correct value. The same problem exists with your function declarations. A()
, B()
, and C()
are all declared as functions "returning bool
and taking an unspecified number of parameters".
To see the kind of problems that may have, let's write a program:
#include <stdio.h>
int test_zero(void)
{
return 42;
}
static int test_one(char *data)
{
return printf("%s\n", data);
}
int main(void)
{
/* a is of type "pointer to function returning int
and taking unspecified number of parameters */
int (*a)();
/* b is of type "pointer to function returning int
and taking no parameters */
int (*b)(void);
/* This is OK */
a = test_zero;
printf("a: %d\n", a());
a = test_one; /* OK, since compiler doesn't check the parameters */
printf("a: %d\n", a()); /* oops, wrong number of args */
/* This is OK too */
b = test_zero;
printf("b: %d\n", b());
/* The compiler now does type checking, and sees that the
assignment is wrong, so it can warn us */
b = test_one;
printf("b: %d\n", b()); /* Wrong again */
return 0;
}
When I compile the above with gcc, it says:
warning: assignment from incompatible pointer type
for the line b = test_one;
, which is good. There is no warning for the corresponding assignment to a
.
So, you should declare your functions as:
bool A(void);
bool B(void);
bool C(void);
And then the variable to hold the function should be declared as:
bool (*choice)(void);
To help you get the desired outcome in perhaps a different way than you asked:
render: function() {
...
<a data-tag={i} style={showStyle} onClick={this.removeTag.bind(null, i)}></a>
...
},
removeTag: function(i) {
// do whatever
},
Notice the bind()
. Because this is all javascript, you can do handy things like that. We no longer need to attach data to DOM nodes in order to keep track of them.
IMO this is much cleaner than relying on DOM events.
Update April 2017: These days I would write onClick={() => this.removeTag(i)}
instead of .bind

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.
I did not found any solution here that show how to pass method with parameters bound to it as a parameter of a method. Bellow is example of how you can pass a method with parameter values already bound to it.
public interface Do {
void run() throws Exception;
}
public interface Return {
R run() throws Exception;
}
//example - when passed method does not return any value
public void tx(final Do func) throws Exception {
connectionScope.beginTransaction();
try {
func.run();
connectionScope.commit();
} catch (Exception e) {
connectionScope.rollback();
throw e;
} finally {
connectionScope.close();
}
}
//Invoke code above by
tx(() -> api.delete(6));
Another example shows how to pass a method that actually returns something
public R tx(final Return func) throws Exception {
R r=null;
connectionScope.beginTransaction();
try {
r=func.run();
connectionScope.commit();
} catch (Exception e) {
connectionScope.rollback();
throw e;
} finally {
connectionScope.close();
}
return r;
}
//Invoke code above by
Object x= tx(() -> api.get(id));
A cookie is just another HTTP header. You can always set it while making a HTTP call with the apache library or with HTTPUrlConnection. Either way you should be able to read and set HTTP cookies in this fashion.
You can read this article for more information.
I can share my peace of code to demonstrate how easy you can make it.
public static String getServerResponseByHttpGet(String url, String token) {
try {
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(url);
get.setHeader("Cookie", "PHPSESSID=" + token + ";");
Log.d(TAG, "Try to open => " + url);
HttpResponse httpResponse = client.execute(get);
int connectionStatusCode = httpResponse.getStatusLine().getStatusCode();
Log.d(TAG, "Connection code: " + connectionStatusCode + " for request: " + url);
HttpEntity entity = httpResponse.getEntity();
String serverResponse = EntityUtils.toString(entity);
Log.d(TAG, "Server response for request " + url + " => " + serverResponse);
if(!isStatusOk(connectionStatusCode))
return null;
return serverResponse;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {

There's actually an easier way than exporting and unsetting or sourcing again (at least in bash, as long as you're ok with passing the environment variables manually):
let a.sh be
#!/bin/bash
secret="winkle my tinkle"
echo Yo, lemme tell you \"$secret\", b.sh!
Message=$secret ./b.sh
and b.sh be
#!/bin/bash
echo I heard \"$Message\", yo
Observed output is
[rob@Archie test]$ ./a.sh
Yo, lemme tell you "winkle my tinkle", b.sh!
I heard "winkle my tinkle", yo
The magic lies in the last line of a.sh
, where Message
, for only the duration of the invocation of ./b.sh
, is set to the value of secret
from a.sh
.
Basically, it's a little like named parameters/arguments. More than that, though, it even works for variables like $DISPLAY
, which controls which X Server an application starts in.
Remember, the length of the list of environment variables is not infinite. On my system with a relatively vanilla kernel, xargs --show-limits
tells me the maximum size of the arguments buffer is 2094486 bytes. Theoretically, you're using shell scripts wrong if your data is any larger than that (pipes, anyone?)
Angular RC5 & RC6
If you are getting the above mentioned error in your Jasmine tests, it is most likely because you have to declare the unrenderable component in your TestBed.configureTestingModule({})
.
The TestBed configures and initializes an environment for unit testing and provides methods for mocking/creating/injecting components and services in unit tests.
If you don't declare the component before your unit tests are executed, Angular will not know what <courses></courses>
is in your template file.
Here is an example:
import {async, ComponentFixture, TestBed} from "@angular/core/testing";
import {AppComponent} from "../app.component";
import {CoursesComponent} from './courses.component';
describe('CoursesComponent', () => {
let component: CoursesComponent;
let fixture: ComponentFixture<CoursesComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
AppComponent,
CoursesComponent
],
imports: [
BrowserModule
// If you have any other imports add them here
]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(CoursesComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
While Shannon's answer is technically correct, it looks like overkill.
The simple solution is that you need to put your summation outside of the case
statement.
This should do the trick:
sum(CASE WHEN col1 > col2 THEN col3*col4 ELSE 0 END) AS some_product
Basically, your old code tells SQL to execute the sum(X*Y)
for each line individually (leaving each line with its own answer that can't be grouped).
The code line I have written takes the sum product, which is what you want.

Look at all the issues surrounding trying to make divs perform like tables. They had to add table-xxx to mimic table layouts
Tables are supported and work very well in all browsers. Why ditch them? the fact that they had to mimic them is proof they did their job and well.
In my opinion use the best tool for the job and if you want tabulated data or something that resembles tabulated data tables just work.
Very Late reply I know but worth voicing.
I add in myApp.java, after @SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
And changed
@SpringBootApplication => @Configuration
So, I have this in my main class (myApp.java)
package br.com.company.project.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class SomeApplication {
public static void main(String[] args) {
SpringApplication.run(SomeApplication.class, args);
}
}
And work for me! =)
You can use Membership operator:
def list = ['Grace','Rob','Emmy']
assert ('Emmy' in list)
You can use unix timestamp to direct:
SELECT UNIX_TIMESTAMP(date) AS epoch_time FROM table;
Then get the epoch_time into JavaScript, and it's a simple matter of:
var myDate = new Date(epoch_time * 1000);
The multiplying by 1000 is because JavaScript takes milliseconds, and UNIX_TIMESTAMP gives seconds.
Here is the Swift 4 version.

The representation of the values 65529u and -7 are identical for 16-bit ints. Only the interpretation of the bits is different.
For larger ints and these values, you need to sign extend; one way is with logical operations
int y = (int )(x | 0xffff0000u); // assumes 16 to 32 extension, x is > 32767
If speed is not an issue, or divide is fast on your processor,
int y = ((int ) (x * 65536u)) / 65536;
The multiply shifts left 16 bits (again, assuming 16 to 32 extension), and the divide shifts right maintaining the sign.
How about:

String retVal = "";
try {
retVal = URLEncoder.encode(in_, "UTF8");
} catch (UnsupportedEncodingException ex) {

}
return retVal;
}
I am adding to the first answer.
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch ' HEAD
There will be some merge conflict from origin/master.
Your branch and 'origin/master' have diverged, and have 114 and 109 different commits each, respectively. (use "git pull" to merge the remote branch into yours)
Please run this
git reset --hard origin/master
It will throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master.
I'll be up-front about my preference for natural keys - use them where possible, as they'll make your life of database administration a lot easier. I established a standard in our company that all tables have the following columns:
SUSER_SNAME()
in T-SQL))Row ID has a unique key on it per table, and in any case is auto-generated per row (and permissions prevent anyone editing it), and is reasonably guaranteed to be unique across all tables and databases. If any ORM systems need a single ID key, this is the one to use.
Meanwhile, the actual PK is, if possible, a natural key. My internal rules are something like:
EventId, AttendeeId
)So ideally you end up with a natural, human-readable and memorable PK, and an ORM-friendly one-ID-per-table GUID.
Caveat: the databases I maintain tend to the 100,000s of records rather than millions or billions, so if you have experience of larger systems which contraindicates my advice, feel free to ignore me!
The array decays to a pointer when passed.
Section 6.4 of the C FAQ covers this very well and provides the K&R references etc.
That aside, imagine it were possible for the function to know the size of the memory allocated in a pointer. You could call the function two or more times, each time with different input arrays that were potentially different lengths; the length would therefore have to be passed in as a secret hidden variable somehow. And then consider if you passed in an offset into another array, or an array allocated on the heap (malloc
and all being library functions - something the compiler links to, rather than sees and reasons about the body of).
Its getting difficult to imagine how this might work without some behind-the-scenes slice objects and such right?
Symbian did have a AllocSize()
function that returned the size of an allocation with malloc()
; this only worked for the literal pointer returned by the malloc, and you'd get gobbledygook or a crash if you asked it to know the size of an invalid pointer or a pointer offset from one.
You don't want to believe its not possible, but it genuinely isn't. The only way to know the length of something passed into a function is to track the length yourself and pass it in yourself as a separate explicit parameter.
I'm aware the question is php
oriented, but the best way to redirect a POST
request is probably using .htaccess
, ie:
RewriteEngine on
RewriteCond %{REQUEST_URI} string_to_match_in_url
RewriteCond %{REQUEST_METHOD} POST
RewriteRule ^(.*)$ https://domain.tld/$1 [L,R=307]
Explanation:
By default, if you want to redirect request with POST data, browser redirects it via GET with 302 redirect
. This also drops all the POST data associated with the request. Browser does this as a precaution to prevent any unintentional re-submitting of POST transaction.
But what if you want to redirect anyway POST request with it’s data? In HTTP 1.1, there is a status code for this. Status code 307
indicates that the request should be repeated with the same HTTP method and data. So your POST request will be repeated along with it’s data if you use this status code.
This is what I came up with, I don't know why there is a small delay before closing.

setTimeout(window.close, 0);
Simply, to enforce JAVA version to Ant in Eclipse:
Use RunAs option on Ant file then select External Tool Configuration in JRE tab define your JDK/JRE version you want to use.
You can cast an integer to a string in this way
intval::text
and so in your case
SELECT * FROM table WHERE <some integer>::text = 'string of numbers'
If you want to iterate over both keys and values of the dictionary, do this:

print key, value
Is there a way to initialize the
EntityManager
without a persistence unit defined?
You should define at least one persistence unit in the persistence.xml
deployment descriptor.
Can you give all the required properties to create an
Entitymanager
?
persistence.xml
file:<persistence>
<persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
SOME_PROPERTIES
</persistence-unit>
</persistence>
In Java EE environments, the
jta-data-source
andnon-jta-data-source
elements are used to specify the global JNDI name of the JTA and/or non-JTA data source to be used by the persistence provider.
So if your target Application Server supports JTA (JBoss, Websphere, GlassFish), your persistence.xml
looks like:
<persistence>
<persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
<!--GLOBAL_JNDI_GOES_HERE-->
<jta-data-source>jdbc/myDS</jta-data-source>
</persistence-unit>
</persistence>
If your target Application Server does not support JTA (Tomcat), your persistence.xml
looks like:
<persistence>
<persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
<!--GLOBAL_JNDI_GOES_HERE-->
<non-jta-data-source>jdbc/myDS</non-jta-data-source>
</persistence-unit>
</persistence>
If your data source is not bound to a global JNDI (for instance, outside a Java EE container), so you would usually define JPA provider, driver, url, user and password properties. But property name depends on the JPA provider. So, for Hibernate as JPA provider, your persistence.xml
file will looks like:
<persistence>
<persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>br.com.persistence.SomeClass</class>
<properties>
<property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.ClientDriver"/>
<property name="hibernate.connection.url" value="jdbc:derby://localhost:1527/EmpServDB;create=true"/>
<property name="hibernate.connection.username" value="APP"/>
<property name="hibernate.connection.password" value="APP"/>
</properties>
</persistence-unit>
</persistence>
Transaction Type Attribute
In general, in Java EE environments, a transaction-type of
RESOURCE_LOCAL
assumes that a non-JTA datasource will be provided. In a Java EE environment, if this element is not specified, the default is JTA. In a Java SE environment, if this element is not specified, a default ofRESOURCE_LOCAL
may be assumed.
I need to create the
EntityManager
from the user's specified values at runtime
So use this:
Map addedOrOverridenProperties = new HashMap();
// Let's suppose we are using Hibernate as JPA provider
addedOrOverridenProperties.put("hibernate.show_sql", true);
Persistence.createEntityManagerFactory(<PERSISTENCE_UNIT_NAME_GOES_HERE>, addedOrOverridenProperties);
We use object-scan for a lot of data processing. It has some nice properties, especially traversing in delete safe order. Here is how one could implement find, delete and replace for your question.
// const objectScan = require('object-scan');
const tool = (() => {
const scanner = objectScan(['[*]'], {
abort: true,
rtn: 'bool',
filterFn: ({
value, parent, property, context
}) => {
if (value.id === context.id) {
context.fn({ value, parent, property });
return true;
}
return false;
}
});
return {
add: (data, id, obj) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property + 1, 0, obj) }),
del: (data, id) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property, 1) }),
mod: (data, id, prop, v = undefined) => scanner(data, {
id,
fn: ({ value }) => {
if (value !== undefined) {
value[prop] = v;
} else {
delete value[prop];
}
}
})
};
})();
// -------------------------------
const data = [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ];
const toAdd = { id: 'two', pId: 'foo2', cId: 'bar2' };
const exec = (fn) => {
console.log('---------------');
console.log(fn.toString());
console.log(fn());
console.log(data);
};
exec(() => tool.add(data, 'one', toAdd));
exec(() => tool.mod(data, 'one', 'pId', 'zzz'));
exec(() => tool.mod(data, 'one', 'other', 'test'));
exec(() => tool.mod(data, 'one', 'gone', 'delete me'));
exec(() => tool.mod(data, 'one', 'gone'));
exec(() => tool.del(data, 'three'));
// => ---------------

If you really need to use sys.path.insert, consider leaving sys.path[0] as it is:
sys.path.insert(1, path_to_dev_pyworkbooks)
This could be important since 3rd party code may rely on sys.path documentation conformance:
As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter.
The BOOLEAN data type is a PL/SQL data type. Oracle does not provide an equivalent SQL data type (...) you can create a wrapper function which maps a SQL type to the BOOLEAN type.

I've been through basically all of stackoverflow for this error and nothing resolved my issue. I was able to log into mysql directly from the linux command line fine, but with the same user and password couldn't log into phpmyadmin.
So I beat my head against the wall for half the day until I realized it wasn't even reading the config.inc.php under /etc/phpmyadmin (the only place it was located btw based on "find / -iname config.inc.php". So I changed the host in /usr/share/phpMyAdmin/libraries/config.default.php and it finally worked.
I know there's probably another issue with why it isn't reading the config from the /etc/phpmyadmin folder but I can't be bothered with that for now :P
tldr; if your settings don't seem to be applying at all try making the changes within /usr/share/phpMyAdmin/libraries/config.default.php
The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn't need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I'll most likely continue to use Apple's JRE for running the IDE since it's probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.
Try this:
#!/bin/bash
stat --format %y $(ls -t $(find alfa/ -type f) | head -n 1)
It uses find
to gather all files from the directory, ls
to list them sorted by modification date, head
for selecting the first file and finally stat
to show the time in a nice format.
At this time it is not safe for files with whitespace or other special characters in their names. Write a commend if it doesn't meet your needs yet.
If you don't need branch or tag name:
git log --oneline --graph --all --no-decorate
If you don't even need color (to avoid tty color sequence):
git log --oneline --graph --all --no-decorate --no-color
And a handy alias (in .gitconfig) to make life easier:
[alias]
tree = log --oneline --graph --all --no-decorate
Only last option takes effect, so it's even possible to override your alias:
git tree --decorate
Use this one:
Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & ws.Name & "'!" & range1.Address
End With
Note that when you're using Dim range1, rng As range
, only rng
has type of Range
, but range1
is Variant
. That's why I'm using Dim range1 As Range, rng As Range
.
About meaning of parameters you can read is MSDN, but in short:
Type:=xlValidateList
means validation type, in that case you should select value from listAlertStyle:=xlValidAlertStop
specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.Operator:= xlBetween
is odd. It can be used only if two formulas are provided for validation.Formula1:="='" & ws.Name & "'!" & range1.Address
for list data validation provides address of list with values (in format =Sheet!A1:A5
)I was also facing this issue. You might have more than JAVA versions installed. Make sure that JAVA_HOME variable is set to the correct version.
These are terms usually used when describing a "FIFO" queue, that is "first in, first out". This works like a line. You decide to go to the movies. There is a long line to buy tickets, you decide to get into the queue to buy tickets, that is "Enqueue". at some point you are at the front of the line, and you get to buy a ticket, at which point you leave the line, that is "Dequeue".
This line:
private dynamic defaultReminder =
reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder
will be initialized before defaultReminder
, so the above line might throw a NullReferenceException
.
Instead, just use:
private dynamic defaultReminder = TimeSpan.FromMinutes(15);
Alternatively, set up the value in the constructor:
private dynamic defaultReminder;
public Reminders()
{
defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}
There are more details about this compiler error on MSDN - Compiler Error CS0236.

self.stream.flush()
self.data += data
tmp = str(self.data)
if '\x0a' in tmp or '\x0d' in tmp:
tmp = tmp.rstrip('\x0a\x0d')
log.info('%s%s' % (self.prefix, tmp))
self.data = ''

I'm using a message service that wraps an rxjs Subject
(TypeScript)
Plunker example: Message Service
import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';
import { Subscription } from 'rxjs/Subscription';
import 'rxjs/add/operator/filter'
import 'rxjs/add/operator/map'
interface Message {
type: string;
payload: any;
}
type MessageCallback = (payload: any) => void;
@Injectable()
export class MessageService {
private handler = new Subject<Message>();
broadcast(type: string, payload: any) {
this.handler.next({ type, payload });
}
subscribe(type: string, callback: MessageCallback): Subscription {
return this.handler
.filter(message => message.type === type)
.map(message => message.payload)
.subscribe(callback);
}
}
Components can subscribe and broadcast events (sender):
import { Component, OnDestroy } from '@angular/core'
import { MessageService } from './message.service'
import { Subscription } from 'rxjs/Subscription'
@Component({
selector: 'sender',
template: ...
})
export class SenderComponent implements OnDestroy {
private subscription: Subscription;
private messages = [];
private messageNum = 0;
private name = 'sender'
constructor(private messageService: MessageService) {
this.subscription = messageService.subscribe(this.name, (payload) => {
this.messages.push(payload);
});
}
send() {
let payload = {
text: `Message ${++this.messageNum}`,
respondEvent: this.name
}
this.messageService.broadcast('receiver', payload);
}
clear() {
this.messages = [];
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
(receiver)
import { Component, OnDestroy } from '@angular/core'
import { MessageService } from './message.service'
import { Subscription } from 'rxjs/Subscription'
@Component({
selector: 'receiver',
template: ...
})
export class ReceiverComponent implements OnDestroy {
private subscription: Subscription;
private messages = [];
constructor(private messageService: MessageService) {
this.subscription = messageService.subscribe('receiver', (payload) => {
this.messages.push(payload);
});
}
send(message: {text: string, respondEvent: string}) {
this.messageService.broadcast(message.respondEvent, message.text);
}
clear() {
this.messages = [];
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
The subscribe
method of MessageService
returns an rxjs Subscription
object, which can be unsubscribed from like so:
import { Subscription } from 'rxjs/Subscription';
...
export class SomeListener {
subscription: Subscription;
constructor(private messageService: MessageService) {
this.subscription = messageService.subscribe('someMessage', (payload) => {
console.log(payload);
this.subscription.unsubscribe();
});
}
}

This is a similar way I'm using here to generate an unique error code, based on Anton Purin answer, but relying on the more appropriate org.apache.commons.text.RandomStringGenerator
instead of the (once, not anymore) deprecated org.apache.commons.lang3.RandomStringUtils
:
@Singleton
@Component
public class ErrorCodeGenerator implements Supplier<String> {
private RandomStringGenerator errorCodeGenerator;
public ErrorCodeGenerator() {
errorCodeGenerator = new RandomStringGenerator.Builder()
.withinRange('0', 'z')
.filteredBy(t -> t >= '0' && t <= '9', t -> t >= 'A' && t <= 'Z', t -> t >= 'a' && t <= 'z')
.build();
}
@Override
public String get() {
return errorCodeGenerator.generate(8);
}
}

I just had this issue myself. 3 points that will hopefully help:
app/assets/images
directory, then you should be able to call the image directly with no prefix in the path. ie. image_url('logo.png')
background-image:
property, then your line of code should be background-image: image-url('logo.png')
. This works for both less and sass stylesheets. If you are using it inline in the view, then you will need to use the built in image_tag
helper in rails to output your image. Once again, no prefixing <%= image_tag 'logo.png' %>
rake assets:precompile
to generate your assets, or rake assets:precompile RAILS_ENV=production
for production, otherwise, your production environment will not have the fingerprinted assets when loading the page.Also for those commands in point 3 you will need to prefix them with bundle exec
if you are running bundler.
It's done by binding to the scroll event of the container (usually window).
Quick example:
// Cache selectors
var topMenu = $("#top-menu"),
topMenuHeight = topMenu.outerHeight()+15,
// All list items
menuItems = topMenu.find("a"),
// Anchors corresponding to menu items
scrollItems = menuItems.map(function(){
var item = $($(this).attr("href"));
if (item.length) { return item; }
});
// Bind to scroll
$(window).scroll(function(){
// Get container scroll position
var fromTop = $(this).scrollTop()+topMenuHeight;
// Get id of current scroll item
var cur = scrollItems.map(function(){
if ($(this).offset().top < fromTop)
return this;
});
// Get the id of the current element
cur = cur[cur.length-1];
var id = cur && cur.length ? cur[0].id : "";
// Set/remove active class
menuItems
.parent().removeClass("active")
.end().filter("[href='#"+id+"']").parent().addClass("active");
});?
See the above in action at jsFiddle including scroll animation.

In C99, you can use setjmp
/longjmp
for non-local control flow.
Within a single scope, the generic, structured coding pattern for C in the presence of multiple resource allocations and multiple exits uses goto
, like in this example. This is similar to how C++ implements destructor calls of automatic objects under the hood, and if you stick to this diligently, it should allow you for a certain degree of cleanness even in complex functions.

Changing the format to a firm format may fix the problem, provided you restore back the previous format before leaving the BAT file. But it may be subject to nasty race conditions and complicate recovery in cancelled BAT files.
Fortunately, there is an alternative.
You may use WMIC, instead. WMIC Path Win32_LocalTime Get Day,Hour,Minute,Month,Second,Year /Format:table
returns the date and time in a invariable way. Very convenient to directly parse it with a FOR /F
command.
So, putting the pieces together, try this as a starting point...
SETLOCAL enabledelayedexpansion
FOR /F "skip=1 tokens=1-6" %%A IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
SET /A FD=%%F*1000000+%%D*100+%%A
SET /A FT=10000+%%B*100+%%C
SET FT=!FT:~-4!
ECHO Archive_!FD!_!FT!.zip
)
I just spent about 1 hour to figure out possible solution for the same error.
So what I did under MS WIndows 7 is following
Uninstall all Java packages of all versions.
Download last packages Java SE or JRE for your 32 or 64 Windows and install it.
First install JRE and second is Java SE.
Open text editor and paste this code.
public class Hello {
public static void main(String[] args) {
System.out.println("test");
}
}
Save it like Hello.java
Go to Console and compile it like
javac Hello.java
java Hello
Should be no error.
Very nice example using paste and substitute to typeset both symbols (mathplot) and variables at http://vis.supstat.com/2013/04/mathematical-annotation-in-r/
Here is a ggplot adaptation
library(ggplot2)
x_mean <- 1.5
x_sd <- 1.2
N <- 500
n <- ggplot(data.frame(x <- rnorm(N, x_mean, x_sd)),aes(x=x)) +
geom_bar() + stat_bin() +
labs(title=substitute(paste(
"Histogram of random data with ",
mu,"=",m,", ",
sigma^2,"=",s2,", ",
"draws = ", numdraws,", ",
bar(x),"=",xbar,", ",
s^2,"=",sde),
list(m=x_mean,xbar=mean(x),s2=x_sd^2,sde=var(x),numdraws=N)))
print(n)
The mappedBy
attribute is referencing customer
while the property is mCustomer
, hence the error message. So either change your mapping into:
/** The collection of stores. */
@OneToMany(mappedBy = "mCustomer", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Collection<Store> stores;
Or change the entity property into customer
(which is what I would do).
The mappedBy reference indicates "Go look over on the bean property named 'customer' on the thing I have a collection of to find the configuration."
You should update eslint config file to fix this permanently. Else you can temporarily enable or disable eslint check for console like below
/* eslint-disable no-console */
console.log(someThing);
/* eslint-enable no-console */
Typically an alternative for fixed size Lists are Java arrays. Lists by default are allowed to grow/shrink in Java. However, that does not mean you cannot have a List of a fixed size. You'll need to do some work and create a custom implementation.
You can extend an ArrayList with custom implementations of the clear, add and remove methods.
e.g.
import java.util.ArrayList;
public class FixedSizeList<T> extends ArrayList<T> {
public FixedSizeList(int capacity) {
super(capacity);
for (int i = 0; i < capacity; i++) {
super.add(null);
}
}
public FixedSizeList(T[] initialElements) {
super(initialElements.length);
for (T loopElement : initialElements) {
super.add(loopElement);
}
}
@Override
public void clear() {
throw new UnsupportedOperationException("Elements may not be cleared from a fixed size List.");
}
@Override
public boolean add(T o) {
throw new UnsupportedOperationException("Elements may not be added to a fixed size List, use set() instead.");
}
@Override
public void add(int index, T element) {
throw new UnsupportedOperationException("Elements may not be added to a fixed size List, use set() instead.");
}
@Override
public T remove(int index) {
throw new UnsupportedOperationException("Elements may not be removed from a fixed size List.");
}
@Override
public boolean remove(Object o) {
throw new UnsupportedOperationException("Elements may not be removed from a fixed size List.");
}
@Override
protected void removeRange(int fromIndex, int toIndex) {
throw new UnsupportedOperationException("Elements may not be removed from a fixed size List.");
}
}
I like to use: ArgumentException
, ArgumentNullException
, and ArgumentOutOfRangeException
.
ArgumentException
– Something is wrong with the argument.ArgumentNullException
– Argument is null.ArgumentOutOfRangeException
– I don’t use this one much, but a common use is indexing into a collection, and giving an index which is to large.There are other options, too, that do not focus so much on the argument itself, but rather judge the call as a whole:
InvalidOperationException
– The argument might be OK, but not in the current state of the object. Credit goes to STW (previously Yoooder). Vote his answer up as well.NotSupportedException
– The arguments passed in are valid, but just not supported in this implementation. Imagine an FTP client, and you pass a command in that the client doesn’t support.The trick is to throw the exception that best expresses why the method cannot be called the way it is. Ideally, the exception should be detailed about what went wrong, why it is wrong, and how to fix it.
I love when error messages point to help, documentation, or other resources. For example, Microsoft did a good first step with their KB articles, e.g. “Why do I receive an "Operation aborted" error message when I visit a Web page in Internet Explorer?”. When you encounter the error, they point you to the KB article in the error message. What they don’t do well is that they don’t tell you, why specifically it failed.
Thanks to STW (ex Yoooder) again for the comments.
In response to your followup, I would throw an ArgumentOutOfRangeException
. Look at what MSDN says about this exception:
ArgumentOutOfRangeException
is thrown when a method is invoked and at least one of the arguments passed to the method is not null reference (Nothing
in Visual Basic) and does not contain a valid value.
So, in this case, you are passing a value, but that is not a valid value, since your range is 1–12. However, the way you document it makes it clear, what your API throws. Because although I might say ArgumentOutOfRangeException
, another developer might say ArgumentException
. Make it easy and document the behavior.
if you do not want to be bothered by the date format, you could compare the column with the general date format, for example
select *
From table
where cast (RegistrationDate as date) between '20161201' and '20161220'
make sure the date is in DATE format, otherwise cast (col as DATE)
You can use '';
to declaring NULL variable in Javascript
I just went through this myself and chose to set the default value at the reducer INIT function.
If you bind your select with redux then best not 'de-bind' it with a select default value that doesn't represent the actual value, instead set the value when you initialize the object.
As EJP said, it's a message shown because of a call to a non-https protocol. If you are sure it is HTTPS, check your bypass proxy settings, and in case add your webservice host url to the bypass proxy list
It is sometimes convenient to employ the "send/recv" family of system calls. If the flags
parameter contains the MSG_DONTWAIT
flag, each call will behave similar to a socket having the O_NONBLOCK
flag set.
ssize_t send(int sockfd, const void *buf, size_t len, int flags);
ssize_t recv(int sockfd, void *buf, size_t len, int flags);
You may try:
wget --user-agent=Mozilla --content-disposition --mirror --convert-links -E -K -p http://example.com/
Also you can add:
-A pdf,ps,djvu,tex,doc,docx,xls,xlsx,gz,ppt,mp4,avi,zip,rar
to accept the specific extensions, or to reject only specific extensions:
-R html,htm,asp,php
or to exclude the specific areas:
-X "search*,forum*"
If the files are ignored for robots (e.g. search engines), you've to add also: -e robots=off
Delete the unit testing from your project follow the below steps this will solve the issue.
select your project from the project navigator to open the project editor. From the target delete the test from the left side of the project editor and press the Delete key.
An initial reaction to this would be to ask and ensure that the two object files are being linked together. This is done at the compile stage by compiling both files at the same time:
gcc -o programName a.c b.c
Or if you want to compile separately, it would be:
gcc -c a.c
gcc -c b.c
gcc -o programName a.o b.o
Suppose the file you want to call is anotherfile.py and the method you want to call is method1, then first import the file and then the method
from anotherfile import method1
if method1 is part of a class, let the class be class1, then
from anotherfile import class1
then create an object of class1, suppose the object name is ob1, then
ob1 = class1()
ob1.method1()
The command in DougWare's answer did not work, but this did:
reg delete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v FOOBAR /f
The shortcut HKLM
can be used for HKEY_LOCAL_MACHINE
.
You can also delete cookies without using jquery.cookie plugin:
document.cookie = 'NAMEOFYOURCOOKIE' + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
I suggest to read this since I believe that is what are you looking for.https://en.wikipedia.org/wiki/Erase%E2%80%93remove_idiom
If you use for example
vec.erase(vec.begin() + 1, vec.begin() + 3);
you will erase n -th element of vector but when you erase second element, all other elements of vector will be shifted and vector sized will be -1. This can be problem if you loop through vector since vector size() is decreasing. If you have problem like this provided link suggested to use existing algorithm in standard C++ library. and "remove" or "remove_if".
Hope that this helped
Just to generate the java classes from wsdl to me the best tool is "cxf wsdl2java". Its pretty simple and easy to use. I have found some complexities with some data type in axis2. But unfortunately you can't use those client stub code in your android application because android environment doesn't allow the "java/javax" package name in compiling time unless you rename the package name.
And in the android.jar all the javax.* sources for web service consuming are not available. To resolve these I have developed this WS Client Generation Tool for android.
In background it uses "cxf wsdl2java" to generate the java client stub for android platform for you, And I have written some sources to consume the web service in a smarter way.
Just give the wsdl file location it will give you the sources and some library. you have to just put the sources and the libraries in your project. and you can just call it in some "method call fashion" just we do in our enterprise project, you don't need to know the namespace/soap action etc. For example, you have a service to login, what you need to do is :
LoginService service = new LoginService ( );
Login login = service.getLoginPort ( );
LoginServiceResponse resp = login.login ( "someUser", "somePass" );
And its fully open and free.
NoClassDefFoundError
is a linkage error basically. It occurs when you try and instantiate an object (statically with "new") and it's not found when it was during compilation.
ClassNotFoundException
is more general and is a runtime exception when you try to use a class that doesn't exist. For example, you have a parameter in a function accepts an interface and someone passes in a class that implements that interface but you don't have access to the class. It also covers case of dynamic class loading, such as using loadClass()
or Class.forName()
.
Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.
NB - You need to do this first on a test copy of your table!
When I did it, I found that unless I also included AND n1.id <> n2.id
, it deleted every row in the table.
If you want to keep the row with the lowest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
If you want to keep the row with the highest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
I used this method in MySQL 5.1
Not sure about other versions.
Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE
, please be advised that using INSERT
and DISTINCT
is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE
, it took more than 2 hours and yet didn't complete.
INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
SELECT DISTINCT cellId,attributeId,entityRowId,value
FROM tableName;
This question has been already answered in Unicode characters in Windows command line - how?
You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.
How do I convert a list of dictionaries to a pandas DataFrame?
The other answers are correct, but not much has been explained in terms of advantages and limitations of these methods. The aim of this post will be to show examples of these methods under different situations, discuss when to use (and when not to use), and suggest alternatives.
DataFrame()
, DataFrame.from_records()
, and .from_dict()
Depending on the structure and format of your data, there are situations where either all three methods work, or some work better than others, or some don't work at all.
Consider a very contrived example.
np.random.seed(0)
data = pd.DataFrame(
np.random.choice(10, (3, 4)), columns=list('ABCD')).to_dict('r')
print(data)
[{'A': 5, 'B': 0, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'C': 3, 'D': 5},
{'A': 2, 'B': 4, 'C': 7, 'D': 6}]
This list consists of "records" with every keys present. This is the simplest case you could encounter.
# The following methods all produce the same output.
pd.DataFrame(data)
pd.DataFrame.from_dict(data)
pd.DataFrame.from_records(data)
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
orient='index'
/'columns'
Before continuing, it is important to make the distinction between the different types of dictionary orientations, and support with pandas. There are two primary types: "columns", and "index".
orient='columns'
Dictionaries with the "columns" orientation will have their keys correspond to columns in the equivalent DataFrame.
For example, data
above is in the "columns" orient.
data_c = [
{'A': 5, 'B': 0, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'C': 3, 'D': 5},
{'A': 2, 'B': 4, 'C': 7, 'D': 6}]
pd.DataFrame.from_dict(data_c, orient='columns')
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
Note: If you are using pd.DataFrame.from_records
, the orientation is assumed to be "columns" (you cannot specify otherwise), and the dictionaries will be loaded accordingly.
orient='index'
With this orient, keys are assumed to correspond to index values. This kind of data is best suited for pd.DataFrame.from_dict
.
data_i ={
0: {'A': 5, 'B': 0, 'C': 3, 'D': 3},
1: {'A': 7, 'B': 9, 'C': 3, 'D': 5},
2: {'A': 2, 'B': 4, 'C': 7, 'D': 6}}
pd.DataFrame.from_dict(data_i, orient='index')
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
This case is not considered in the OP, but is still useful to know.
If you need a custom index on the resultant DataFrame, you can set it using the index=...
argument.
pd.DataFrame(data, index=['a', 'b', 'c'])
# pd.DataFrame.from_records(data, index=['a', 'b', 'c'])
A B C D
a 5 0 3 3
b 7 9 3 5
c 2 4 7 6
This is not supported by pd.DataFrame.from_dict
.
All methods work out-of-the-box when handling dictionaries with missing keys/column values. For example,
data2 = [
{'A': 5, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'F': 5},
{'B': 4, 'C': 7, 'E': 6}]
# The methods below all produce the same output.
pd.DataFrame(data2)
pd.DataFrame.from_dict(data2)
pd.DataFrame.from_records(data2)
A B C D E F
0 5.0 NaN 3.0 3.0 NaN NaN
1 7.0 9.0 NaN NaN NaN 5.0
2 NaN 4.0 7.0 NaN 6.0 NaN
"What if I don't want to read in every single column"? You can easily specify this using the columns=...
parameter.
For example, from the example dictionary of data2
above, if you wanted to read only columns "A', 'D', and 'F', you can do so by passing a list:
pd.DataFrame(data2, columns=['A', 'D', 'F'])
# pd.DataFrame.from_records(data2, columns=['A', 'D', 'F'])
A D F
0 5.0 3.0 NaN
1 7.0 NaN 5.0
2 NaN NaN NaN
This is not supported by pd.DataFrame.from_dict
with the default orient "columns".
pd.DataFrame.from_dict(data2, orient='columns', columns=['A', 'B'])
ValueError: cannot use columns parameter with orient='columns'
Not supported by any of these methods directly. You will have to iterate over your data and perform a reverse delete in-place as you iterate. For example, to extract only the 0th and 2nd rows from data2
above, you can use:
rows_to_select = {0, 2}
for i in reversed(range(len(data2))):
if i not in rows_to_select:
del data2[i]
pd.DataFrame(data2)
# pd.DataFrame.from_dict(data2)
# pd.DataFrame.from_records(data2)
A B C D E
0 5.0 NaN 3 3.0 NaN
1 NaN 4.0 7 NaN 6.0
json_normalize
for Nested DataA strong, robust alternative to the methods outlined above is the json_normalize
function which works with lists of dictionaries (records), and in addition can also handle nested dictionaries.
pd.json_normalize(data)
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
pd.json_normalize(data2)
A B C D E
0 5.0 NaN 3 3.0 NaN
1 NaN 4.0 7 NaN 6.0
Again, keep in mind that the data passed to json_normalize
needs to be in the list-of-dictionaries (records) format.
As mentioned, json_normalize
can also handle nested dictionaries. Here's an example taken from the documentation.
data_nested = [
{'counties': [{'name': 'Dade', 'population': 12345},
{'name': 'Broward', 'population': 40000},
{'name': 'Palm Beach', 'population': 60000}],
'info': {'governor': 'Rick Scott'},
'shortname': 'FL',
'state': 'Florida'},
{'counties': [{'name': 'Summit', 'population': 1234},
{'name': 'Cuyahoga', 'population': 1337}],
'info': {'governor': 'John Kasich'},
'shortname': 'OH',
'state': 'Ohio'}
]
pd.json_normalize(data_nested,
record_path='counties',
meta=['state', 'shortname', ['info', 'governor']])
name population state shortname info.governor
0 Dade 12345 Florida FL Rick Scott
1 Broward 40000 Florida FL Rick Scott
2 Palm Beach 60000 Florida FL Rick Scott
3 Summit 1234 Ohio OH John Kasich
4 Cuyahoga 1337 Ohio OH John Kasich
For more information on the meta
and record_path
arguments, check out the documentation.
Here's a table of all the methods discussed above, along with supported features/functionality.
* Use orient='columns'
and then transpose to get the same effect as orient='index'
.
you can try below:
UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(0, cell.contentView.frame.size.height - 1.0, cell.contentView.frame.size.width, 1)];
separator.backgroundColor = myColor;
[cell.contentView addSubview:separator];
or
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"separator.png"]];
imageView.frame = CGRectMake(0, 100, 320, 1);
[customCell.contentView addSubview:imageView];
return customCell;
}
hope you are doing well.when I started work with Android Fragments
then I was also having the same problem then I read about
1- How to switch fragment with other.
2- How to add fragment if Fragment container
does not have any fragment.
then after some R&D, I created a function which helps me in many Projects till now and I am still using this simple function.
public void switchFragment(BaseFragment baseFragment) {
try {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
if (getSupportFragmentManager().findFragmentById(R.id.home_frame) == null) {
ft.add(R.id.home_frame, baseFragment);
} else {
ft.replace(R.id.home_frame, baseFragment);
}
ft.addToBackStack(null);
ft.commit();
} catch (Exception e) {
e.printStackTrace();
}
}

I solved this in about 1 minute by just reading the startup script (in my case /etc/init.d/oracle-xe):
less /etc/init.d/oracle-xe
At almost the beginning of the file I found:
ORACLE_HOME=[PATH_TO_INSTALLATION_INCLUDING_VERSION_NUMBER]
This was the quickest solution for me because I knew where the script was located, and that it is used for starting/restarting the server.
Of course, this relies on that the version number actually corresponds to the actual server version, which it should for a correctly installed instance.
I think primarily you're getting confused between a program's stack
and any old stack
.
A Stack
Is an abstract data structure which consists of information in a Last In First Out system. You put arbitrary objects onto the stack and then you take them off again, much like an in/out tray, the top item is always the one that is taken off and you always put on to the top.
A Programs Stack
Is a stack, it's a section of memory that is used during execution, it generally has a static size per program and frequently used to store function parameters. You push the parameters onto the stack when you call a function and the function either address the stack directly or pops off the variables from the stack.
A programs stack isn't generally hardware (though it's kept in memory so it can be argued as such), but the Stack Pointer which points to a current area of the Stack is generally a CPU register. This makes it a bit more flexible than a LIFO stack as you can change the point at which the stack is addressing.
You should read and make sure you understand the wikipedia article as it gives a good description of the Hardware Stack which is what you are dealing with.
There is also this tutorial which explains the stack in terms of the old 16bit registers but could be helpful and another one specifically about the stack.
From Nils Pipenbrinck:
It's worthy of note that some processors do not implement all of the instructions for accessing and manipulating the stack (push, pop, stack pointer, etc) but the x86 does because of it's frequency of use. In these situations if you wanted a stack you would have to implement it yourself (some MIPS and some ARM processors are created without stacks).
For example, in MIPs a push instruction would be implemented like:
addi $sp, $sp, -4 # Decrement stack pointer by 4
sw $t0, ($sp) # Save $t0 to stack
and a Pop instruction would look like:
lw $t0, ($sp) # Copy from stack to $t0
addi $sp, $sp, 4 # Increment stack pointer by 4
A more "generic" version(?), allowing none English letters as special characters.

I think this is better, following the good practices of passing parameters to the query:
BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();
You can see it in the documentation, Laravel 5.5.
You can also use the Laravel scout and make it easier with search. Here is the documentation.
I know that this question has an accepted answer but I thought I'd chip in with an alternative which uses array.reduce, seeing that summing an array is the canonical example for reduce:
$scope.sum = function(items, prop){
return items.reduce( function(a, b){
return a + b[prop];
}, 0);
};
$scope.travelerTotal = $scope.sum($scope.traveler, 'Amount');
I use the autolink to "auto underline" the text, but just made an "onClick" that manages it. (I ran into this problem myself)
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:textSize="18dp"
android:autoLink="all"
android:text="@string/twitter"
android:onClick="twitter"/>
public void twitter (View view)
{
try
{
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://twitter.com/onaclovtech"));
startActivity(browserIntent);
}
finally
{
}
}
Doesn't require any permissions, as you are passing the intent off to apps that manage those resources, (I.E. browser).
This was what worked for me. Good luck.
Try this // html example
<span>✓</span>
// css example
span {
content: "\2713";
}
Quite easy... You're doing it wrong, because by that event the control is not there:
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow &&
(e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit)
{
// Here you will get the Control you need like:
DropDownList dl = (DropDownList)e.Row.FindControl("ddlPBXTypeNS");
}
}
That is, it will only be valid for a DataRow
(the actually row with data), and if it's in Edit mode... because you only edit one row at a time. The e.Row.FindControl("ddlPBXTypeNS")
will only find the control that you want.
The reason is because varargs give the option of being called with a non-parametrized object array. So if your type was List < A > ... , it can also be called with List[] non-varargs type.
Here is an example:
public static void testCode(){
List[] b = new List[1];
test(b);
}
@SafeVarargs
public static void test(List<A>... a){
}
As you can see List[] b can contain any type of consumer, and yet this code compiles. If you use varargs, then you are fine, but if you use the method definition after type-erasure - void test(List[]) - then the compiler will not check the template parameter types. @SafeVarargs will suppress this warning.
This code works very fast. It comes from here

While this isn't possible with the video itself, you could use a canvas to draw the frames of the video except for pixels in a color range or whatever. It would take some javascript and such of course. See Video Puzzle (apparently broken at the moment), Exploding Video, and Realtime Video -> ASCII
Object creation variants.
Variant 1 : 'new Object()' -> Object constructor without arguments.
var p1 = new Object(); // 'new Object()' create and return empty object -> {}
var p2 = new Object(); // 'new Object()' create and return empty object -> {}
console.log(p1); // empty object -> {}
console.log(p2); // empty object -> {}
// p1 and p2 are pointers to different objects
console.log(p1 === p2); // false
console.log(p1.prototype); // undefined
// empty object which is in fact Object.prototype
console.log(p1.__proto__); // {}
// empty object to which p1.__proto__ points
console.log(Object.prototype); // {}
console.log(p1.__proto__ === Object.prototype); // true
// null, which is in fact Object.prototype.__proto__
console.log(p1.__proto__.__proto__); // null
console.log(Object.prototype.__proto__); // null
Variant 2 : 'new Object(person)' -> Object constructor with argument.
const person = {
name: 'no name',
lastName: 'no lastName',
age: -1
}
// 'new Object(person)' return 'person', which is pointer to the object ->
// -> { name: 'no name', lastName: 'no lastName', age: -1 }
var p1 = new Object(person);
// 'new Object(person)' return 'person', which is pointer to the object ->
// -> { name: 'no name', lastName: 'no lastName', age: -1 }
var p2 = new Object(person);
// person, p1 and p2 are pointers to the same object
console.log(p1 === p2); // true
console.log(p1 === person); // true
console.log(p2 === person); // true
p1.name = 'John'; // change 'name' by 'p1'
p2.lastName = 'Doe'; // change 'lastName' by 'p2'
person.age = 25; // change 'age' by 'person'
// when print 'p1', 'p2' and 'person', it's the same result,
// because the object they points is the same
console.log(p1); // { name: 'John', lastName: 'Doe', age: 25 }
console.log(p2); // { name: 'John', lastName: 'Doe', age: 25 }
console.log(person); // { name: 'John', lastName: 'Doe', age: 25 }
Variant 3.1 : 'Object.create(person)'. Use Object.create with simple object 'person'. 'Object.create(person)' will create(and return) new empty object and add property '__proto__' to the same new empty object. This property '__proto__' will point to the object 'person'.
const person = {
name: 'no name',
lastName: 'no lastName',
age: -1,
getInfo: function getName() {
return `${this.name} ${this.lastName}, ${this.age}!`;
}
}
var p1 = Object.create(person);
var p2 = Object.create(person);
// 'p1.__proto__' and 'p2.__proto__' points to
// the same object -> 'person'
// { name: 'no name', lastName: 'no lastName', age: -1, getInfo: [Function: getName] }
console.log(p1.__proto__);
console.log(p2.__proto__);
console.log(p1.__proto__ === p2.__proto__); // true
console.log(person.__proto__); // {}(which is the Object.prototype)
// 'person', 'p1' and 'p2' are different
console.log(p1 === person); // false
console.log(p1 === p2); // false
console.log(p2 === person); // false
// { name: 'no name', lastName: 'no lastName', age: -1, getInfo: [Function: getName] }
console.log(person);
console.log(p1); // empty object - {}
console.log(p2); // empty object - {}
// add properties to object 'p1'
// (properties with the same names like in object 'person')
p1.name = 'John';
p1.lastName = 'Doe';
p1.age = 25;
// add properties to object 'p2'
// (properties with the same names like in object 'person')
p2.name = 'Tom';
p2.lastName = 'Harrison';
p2.age = 38;
// { name: 'no name', lastName: 'no lastName', age: -1, getInfo: [Function: getName] }
console.log(person);
// { name: 'John', lastName: 'Doe', age: 25 }
console.log(p1);
// { name: 'Tom', lastName: 'Harrison', age: 38 }
console.log(p2);
// use by '__proto__'(link from 'p1' to 'person'),
// person's function 'getInfo'
console.log(p1.getInfo()); // John Doe, 25!
// use by '__proto__'(link from 'p2' to 'person'),
// person's function 'getInfo'
console.log(p2.getInfo()); // Tom Harrison, 38!
Variant 3.2 : 'Object.create(Object.prototype)'. Use Object.create with built-in object -> 'Object.prototype'. 'Object.create(Object.prototype)' will create(and return) new empty object and add property '__proto__' to the same new empty object. This property '__proto__' will point to the object 'Object.prototype'.
// 'Object.create(Object.prototype)' :
// 1. create and return empty object -> {}.
// 2. add to 'p1' property '__proto__', which is link to 'Object.prototype'
var p1 = Object.create(Object.prototype);
// 'Object.create(Object.prototype)' :
// 1. create and return empty object -> {}.
// 2. add to 'p2' property '__proto__', which is link to 'Object.prototype'
var p2 = Object.create(Object.prototype);
console.log(p1); // {}
console.log(p2); // {}
console.log(p1 === p2); // false
console.log(p1.prototype); // undefined
console.log(p2.prototype); // undefined
console.log(p1.__proto__ === Object.prototype); // true
console.log(p2.__proto__ === Object.prototype); // true
Variant 4 : 'new SomeFunction()'
// 'this' in constructor-function 'Person'
// represents a new instace,
// that will be created by 'new Person(...)'
// and returned implicitly
function Person(name, lastName, age) {
this.name = name;
this.lastName = lastName;
this.age = age;
//-----------------------------------------------------------------
// !--- only for demonstration ---
// if add function 'getInfo' into
// constructor-function 'Person',
// then all instances will have a copy of the function 'getInfo'!
//
// this.getInfo: function getInfo() {
// return this.name + " " + this.lastName + ", " + this.age + "!";
// }
//-----------------------------------------------------------------
}
// 'Person.prototype' is an empty object
// (before add function 'getInfo')
console.log(Person.prototype); // Person {}
// With 'getInfo' added to 'Person.prototype',
// instances by their properties '__proto__',
// will have access to the function 'getInfo'.
// With this approach, instances not need
// a copy of the function 'getInfo' for every instance.
Person.prototype.getInfo = function getInfo() {
return this.name + " " + this.lastName + ", " + this.age + "!";
}
// after function 'getInfo' is added to 'Person.prototype'
console.log(Person.prototype); // Person { getInfo: [Function: getInfo] }
// create instance 'p1'
var p1 = new Person('John', 'Doe', 25);
// create instance 'p2'
var p2 = new Person('Tom', 'Harrison', 38);
// Person { name: 'John', lastName: 'Doe', age: 25 }
console.log(p1);
// Person { name: 'Tom', lastName: 'Harrison', age: 38 }
console.log(p2);
// 'p1.__proto__' points to 'Person.prototype'
console.log(p1.__proto__); // Person { getInfo: [Function: getInfo] }
// 'p2.__proto__' points to 'Person.prototype'
console.log(p2.__proto__); // Person { getInfo: [Function: getInfo] }
console.log(p1.__proto__ === p2.__proto__); // true
// 'p1' and 'p2' points to different objects(instaces of 'Person')
console.log(p1 === p2); // false
// 'p1' by its property '__proto__' reaches 'Person.prototype.getInfo'
// and use 'getInfo' with 'p1'-instance's data
console.log(p1.getInfo()); // John Doe, 25!
// 'p2' by its property '__proto__' reaches 'Person.prototype.getInfo'
// and use 'getInfo' with 'p2'-instance's data
console.log(p2.getInfo()); // Tom Harrison, 38!
Val - values are typed storage constants. Once created its value cant be re-assigned. a new value can be defined with keyword val.
eg. val x: Int = 5
Here type is optional as scala can infer it from the assigned value.
Var - variables are typed storage units which can be assigned values again as long as memory space is reserved.
eg. var x: Int = 5
Data stored in both the storage units are automatically de-allocated by JVM once these are no longer needed.
In scala values are preferred over variables due to stability these brings to the code particularly in concurrent and multithreaded code.
You had two options.
Option 1: simplest makefile = NO MAKEFILE.
Rename "a3driver.cpp" to "a3a.cpp", and then on the command line write:
nmake a3a.exe
And that's it. If you're using GNU Make, use "make" or "gmake" or whatever.
Option 2: a 2-line makefile.
a3a.exe: a3driver.obj
link /out:a3a.exe a3driver.obj
I lived this problem in two days and suddenly I realized it that I am using this click method(for asp button) in a submit button(in html submit button) javascript method...
I mean ->
I have an html submit button and an asp button like these:
<input type="submit" value="Siparisi Gönder" onclick="SendEmail()" />_x000D_
<asp:Button ID="sendEmailButton" runat="server" Text="Gönder" OnClick="SendToEmail" Visible="True"></asp:Button>
_x000D_
SendToEmail() is a server side method in Default.aspx SendEmail() is a javascript method like this:
<script type="text/javascript" lang="javascript">_x000D_
function SendEmail() {_x000D_
document.getElementById('<%= sendEmailButton.UniqueID %>').click();_x000D_
alert("Your message is sending...");_x000D_
}_x000D_
</script>
_x000D_
And this "document.getElementById('<%= sendEmailButton.UniqueID %>').click();" method did not work in just Crome. It was working in IE and Firefox.
Then I tried and tried a lot of ways for executing "SendToEmail()" method in Crome.
Then suddenly I changed html submit button --> just html button like this and now it is working:
<input type="button" value="Siparisi Gönder" onclick="SendEmail()" />
_x000D_
Have a nice days...
It should be noted that the documentation recommends using a Layout
rather than Canvas.drawText
directly. My full answer about using a StaticLayout
is here, but I will provide a summary below.
String text = "This is some text.";
TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);
int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);
Here is a fuller example in the context of a custom view:
public class MyView extends View {
String mText = "This is some text.";
TextPaint mTextPaint;
StaticLayout mStaticLayout;
// use this constructor if creating MyView programmatically
public MyView(Context context) {
super(context);
initLabelView();
}
// this constructor is used when created from xml
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
initLabelView();
}
private void initLabelView() {
mTextPaint = new TextPaint();
mTextPaint.setAntiAlias(true);
mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
mTextPaint.setColor(0xFF000000);
// default to a single line of text
int width = (int) mTextPaint.measureText(mText);
mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
// New API alternate
//
// StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
// .setAlignment(Layout.Alignment.ALIGN_NORMAL)
// .setLineSpacing(1, 0) // multiplier, add
// .setIncludePad(false);
// mStaticLayout = builder.build();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Tell the parent layout how big this view would like to be
// but still respect any requirements (measure specs) that are passed down.
// determine the width
int width;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
if (widthMode == MeasureSpec.EXACTLY) {
width = widthRequirement;
} else {
width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
if (widthMode == MeasureSpec.AT_MOST) {
if (width > widthRequirement) {
width = widthRequirement;
// too long for a single line so relayout as multiline
mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
}
}
}
// determine the height
int height;
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode == MeasureSpec.EXACTLY) {
height = heightRequirement;
} else {
height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
if (heightMode == MeasureSpec.AT_MOST) {
height = Math.min(height, heightRequirement);
}
}
// Required call: set width and height
setMeasuredDimension(width, height);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
// do as little as possible inside onDraw to improve performance
// draw the text on the canvas after adjusting for padding
canvas.save();
canvas.translate(getPaddingLeft(), getPaddingTop());
mStaticLayout.draw(canvas);
canvas.restore();
}

Set style= "display:none;"
. By setting visible=false
, it will not render button in the browser. Thus,client side script wont execute.
<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />
html markup should be
<button id="btnsave" onclick="fncsave()">Save</button>
Change javascript to
