You can just create the required CORS configuration as a bean. As per the code below this will allow all requests coming from any origin. This is good for development but insecure. Spring Docs
@Bean
WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurer() {
@Override
void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
}
}
}
As this post gets a bit of popularity I edited it a bit. Spring Boot 2.x.x changed default JDBC connection pool from Tomcat to faster and better HikariCP. Here comes incompatibility, because HikariCP uses different property of jdbc url. There are two ways how to handle it:
OPTION ONE
There is very good explanation and workaround in spring docs:
Also, if you happen to have Hikari on the classpath, this basic setup does not work, because Hikari has no url property (but does have a jdbcUrl property). In that case, you must rewrite your configuration as follows:
app.datasource.jdbc-url=jdbc:mysql://localhost/test
app.datasource.username=dbuser
app.datasource.password=dbpass
OPTION TWO
There is also how-to in the docs how to get it working from "both worlds". It would look like below. ConfigurationProperties bean would do "conversion" for jdbcUrl
from app.datasource.url
@Configuration
public class DatabaseConfig {
@Bean
@ConfigurationProperties("app.datasource")
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
@Bean
@ConfigurationProperties("app.datasource")
public HikariDataSource dataSource(DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
.build();
}
}
I hope the above answer works for elastic search <7.0 but in 7.0 we cannot specify doc type and it is no longer supported. And in that case if we specify doc type we get similar error.
I you are making use of Elastic search 7.0 and Nest C# lastest version(6.6). There are some breaking changes with ES 7.0 which is causing this issue. This is because we cannot specify doc type and in the version 6.6 of NEST they are using doctype. So in order to solve that untill NEST 7.0 is released, we need to download their beta package
Please go through this link for fixing it
https://xyzcoder.github.io/elasticsearch/nest/2019/04/12/es-70-and-nest-mapping-error.html
EDIT: NEST 7.0 is now released. NEST 7.0 works with Elastic 7.0. See the release notes here for details.

as @Geoffrey pointed out, with spring security, you need a different approach as described here: Spring Boot Security CORS
Think to change JDK used in your project. For me I changed JDK from 1.6 to 1.8 and I updated maven.
Check out this great blog post by John Atten: ASP.NET Identity 2.0: Customizing Users and Roles
It has great step-by-step info on the whole process. Go read it : )
Here are some of the basics.
Extend the default ApplicationUser class by adding new properties (i.e.- Address, City, State, etc.):
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity>
GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
return userIdentity;
}
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
// Use a sensible display name for views:
[Display(Name = "Postal Code")]
public string PostalCode { get; set; }
// Concatenate the address info for display in tables and such:
public string DisplayAddress
{
get
{
string dspAddress = string.IsNullOrWhiteSpace(this.Address) ? "" : this.Address;
string dspCity = string.IsNullOrWhiteSpace(this.City) ? "" : this.City;
string dspState = string.IsNullOrWhiteSpace(this.State) ? "" : this.State;
string dspPostalCode = string.IsNullOrWhiteSpace(this.PostalCode) ? "" : this.PostalCode;
return string.Format("{0} {1} {2} {3}", dspAddress, dspCity, dspState, dspPostalCode);
}
}
Then you add your new properties to your RegisterViewModel.
// Add the new address properties:
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
Then update the Register View to include the new properties.
<div class="form-group">
@Html.LabelFor(m => m.Address, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.Address, new { @class = "form-control" })
</div>
</div>
Then update the Register() method on AccountController with the new properties.
// Add the Address properties:
user.Address = model.Address;
user.City = model.City;
user.State = model.State;
user.PostalCode = model.PostalCode;
To answer your question, Hibernate is an implementation of the JPA standard. Hibernate has its own quirks of operation, but as per the Hibernate docs
By default, Hibernate uses lazy select fetching for collections and lazy proxy fetching for single-valued associations. These defaults make sense for most associations in the majority of applications.
So Hibernate will always load any object using a lazy fetching strategy, no matter what type of relationship you have declared. It will use a lazy proxy (which should be uninitialized but not null) for a single object in a one-to-one or many-to-one relationship, and a null collection that it will hydrate with values when you attempt to access it.
It should be understood that Hibernate will only attempt to fill these objects with values when you attempt to access the object, unless you specify fetchType.EAGER
.
Generally speaking, you can update your index mapping using the put mapping api (reference here) :
curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
"advert_type" : {
"properties" : {
//your new mapping properties
}
}
}
'
It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.
You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.
Finally, you will have to reindex your data for your new mapping to be taken into account.
The best solution would really be to create a new index.
If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.
The following would work:
myarray: [
String1, String2, String3,
String4, String5, String5, String7
]
I tested it using the snakeyaml implementation, I am not sure about other implementations though.
Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity
).
Make sure you refer to the property as fileName
in the Criteria query, not filename
.
Specifically, Hibernate will call the getter method of the filename
property when executing that Criteria query, so it will look for a method called getFilename()
. But the property is called FileName
and the getter getFileName()
.
So, change the projection like so:
criteria.setProjection(Projections.property("fileName"));
Try this.
SELECT
CASE
WHEN FRUIT = 'A' THEN 'APPLE'
WHEN FRUIT = 'B' THEN 'BANANA'
ELSE 'UNKNOWN FRUIT'
END AS FRUIT
FROM FRUIT_TABLE;
If you run docker run <NAME>
it will spawn a new image, which most likely isn't what you want.
If you want to change a current image do the following:
docker ps -a
Take the id of your target container and go to:
cd /var/lib/docker/containers/<conainerID><and then some:)>
Stop the container:
docker stop <NAME>
Change the files
vi config.v2.json
"Config": {
....
"ExposedPorts": {
"80/tcp": {},
"8888/tcp": {}
},
....
},
"NetworkSettings": {
....
"Ports": {
"80/tcp": [
{
"HostIp": "",
"HostPort": "80"
}
],
And change file
vi hostconfig.json
"PortBindings": {
"80/tcp": [
{
"HostIp": "",
"HostPort": "80"
}
],
"8888/tcp": [
{
"HostIp": "",
"HostPort": "8888"
}
]
}
Restart your docker and it should work.
ElasticSearch itself provides a way to create data backup and restoration. The simple command to do it is:
CURL -XPUT 'localhost:9200/_snapshot/<backup_folder name>/<backupname>' -d '{
"indices": "<index_name>",
"ignore_unavailable": true,
"include_global_state": false
}'
Now, how to create, this folder, how to include this folder path in ElasticSearch configuration, so that it will be available for ElasticSearch, restoration method, is well explained here. To see its practical demo surf here.
Not going to be everyone's fix, but it was for me:
So, i ran across this exact issue. The problem I seemed to have was when my DataTable didnt have an ID column, but the target destination had one with a primary key.
When i adapted my DataTable to have an id, the copy worked perfectly.
In my scenario, the Id column isnt very important to have the primary key so i deleted this column from the target destination table and the SqlBulkCopy is working without issue.
It worked for me after adding the following dependency in pom,
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.3.0.Final</version>
</dependency>
create a folder inside htdocs, place your website there, access it via localhost or Internal IP (if you're behind a router) - check out this video demo here
Here is the sample on what worked for me. I think that put method is needed in entity class to map sql columns to java class attributes.
//simpleExample
Query query = em.createNativeQuery(
"SELECT u.name,s.something FROM user u, someTable s WHERE s.user_id = u.id",
NameSomething.class);
List list = (List<NameSomething.class>) query.getResultList();
Entity class:
@Entity
public class NameSomething {
@Id
private String name;
private String something;
// getters/setters
/**
* Generic put method to map JPA native Query to this object.
*
* @param column
* @param value
*/
public void put(Object column, Object value) {
if (((String) column).equals("name")) {
setName(String) value);
} else if (((String) column).equals("something")) {
setSomething((String) value);
}
}
}
Looks like you're trying to both inherit the groupId from the parent, and simultaneously specify the parent using an inherited groupId!
In the child pom, use something like this:
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.felipe</groupId>
<artifactId>tutorial_maven</artifactId>
<version>1.0-SNAPSHOT</version>
<relativePath>../pom.xml</relativePath>
</parent>
<artifactId>tutorial_maven_jar</artifactId>
Using properties like ${project.groupId}
won't work there. If you specify the parent in this way, then you can inherit the groupId and version in the child pom. Hence, you only need to specify the artifactId in the child pom.
allocationSize=1
It is a micro optimization before getting query Hibernate tries to assign value in the range of allocationSize and so try to avoid querying database for sequence. But this query will be executed every time if you set it to 1. This hardly makes any difference since if your data base is accessed by some other application then it will create issues if same id is used by another application meantime .
Next generation of Sequence Id is based on allocationSize.
By defualt it is kept as 50
which is too much. It will also only help if your going to have near about 50
records in one session which are not persisted and which will be persisted using this particular session and transation.
So you should always use allocationSize=1
while using SequenceGenerator
. As for most of underlying databases sequence is always incremented by 1

You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.
Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.
Try changing the name of
PasswordHintAction action;
to
PasswordHintAction passwordHintAction;
so that it matches the bean definition.
Quotes, but I prefer them on the just the value:
url: "http://www.example.com/"
Putting them across the whole line looks like it might cause problems.
I know this question has several answers already, but I think there is a very subtle aspect that, although mentioned, hasn't been highlighted enough in the previous answers.
Before checking the Apache configuration or your files' permissions, let's do a simpler check to make sure that each of the directories composing the full path to the file you want to access (e.g. the index.php file in your document's root) is not only readable but also executable by the web server user.
For example, let's say the path to your documents root is "/var/www/html". You have to make sure that all of the "var", "www" and "html" directories are (readable and) executable by the web server user. In my case (Ubuntu 16.04) I had mistakenly removed the "x" flag to the "others" group from the "html" directory so the permissions looked like this:
drwxr-xr-- 15 root root 4096 Jun 11 16:40 html
As you can see the web server user (to whom the "others" permissions apply in this case) didn't have execute access to the "html" directory, and this was exactly the root of the problem. After issuing a:
chmod o+x html
command, the problem got fixed!
Before resolving this way I had literally tried every other suggestion in this thread, and since the suggestion was buried in a comment that I found almost by chance, I think it may be helpful to highlight and expand on it here.
Change Your Web.Config file as below. It will act like charm.
In node <system.webServer>
add below portion of code
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/>

After adding, your Web.Config will look like below
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/>
</modules>
<httpProtocol>
<customHeaders>

There is a workaround.
That's it.
select the index then select the ones needed then select sql and click action then click rebuild
If you are running IIS 8 with windows server 2012 you need to do the following:
from then on your application should start running
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.using fn_my_permissions
EXECUTE AS USER = 'userName';
SELECT * FROM fn_my_permissions(NULL, 'DATABASE')
You have a couple of questions here, so I'll address them separately:
My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).
You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:
Base table (what you have now):
| id primary_key sequence
| -- other columns here.
Items table:
| id primary_key sequence
| descript VARCHAR(30) UNIQUE
Map table:
| base_id bigint
| items_id bigint
Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.
And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.
If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.
Personally, I would use TEXT
. It does not sound like you'd gain much by making this a BLOB
, and TEXT
, in my experience, is easier to read if you're using some form of IDE.
You could use a Data URI to supply the image data, for example:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<image width="20" height="20" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>
</svg>
The image will go through all normal svg transformations.
But this technique has disadvantages, for example the image will not be cached by the browser
Here's a dictionary that will take any type of key as long as the toString() property returns unique values. The dictionary uses anything as the value for the key value pair.

All versions of rails have a "destroy", so-, if you create a (for example) scaffold named "tasks" using a generator, to destroy all the changes of that generate step you will have to type:
rails destroy scaffold Tasks
Hope it helps you.

But you have to admit it guys this ENTIRE IIS setup configure/guess/trial and see/try this/try that spends 4 or 5 of our days trying to find a solution around approach IS A COMPLETE AND UTTER JOKE.
SURELY, 'IIS' IS THE BIGGEST CONFIDENCE TRICK EVER PLAYED ON MANKIND TO DATE
I had to make some changes to make it work, as some things seem to have changed in the meantime:
Here's a working example, hope this helps (I'm using JodaTime but in this case SimpleDate would be sufficient):
import java.util.Date;
import javax.xml.bind.DatatypeConverter;
import javax.xml.bind.annotation.adapters.XmlAdapter;
import org.joda.time.DateTime;
public class DateAdapter extends XmlAdapter<Object, Object> {
@Override
public Object marshal(Object dt) throws Exception {
return new DateTime((Date) dt).toString("YYYY-MM-dd");
}
@Override
public Object unmarshal(Object s) throws Exception {
return DatatypeConverter.parseDate((String) s).getTime();
}
}
In the xsd, I have followed the excellent references given above, so I have included this xml annotation:
<xsd:appinfo>
<jaxb:schemaBindings>
<jaxb:package name="at.mycomp.xml" />
</jaxb:schemaBindings>
<jaxb:globalBindings>
<jaxb:javaType name="java.util.Date" xmlType="xsd:date"
parseMethod="at.mycomp.xml.DateAdapter.unmarshal"
printMethod="at.mycomp.xml.DateAdapter.marshal" />
</jaxb:globalBindings>
</xsd:appinfo>
I had the same issue, but the problem for me was that Java assertions (e.g. assert(num > 0)) were not enabled for Eclipse, but were enabled when running maven.
Therefore running the jUnit tests from Eclipse did not catch trigger the assertion error.
This is made clear when using jUnit 4.11 (as opposed to the older version I was using) because it prints out the assertion error, e.g.
java.lang.AssertionError: null
at com.company.sdk.components.schema.views.impl.InputViewHandler.<init>(InputViewHandler.java:26)
at test.com.company.sdk.util.TestSchemaExtractor$MockInputViewHandler.<init>(TestSchemaExtractor.java:31)
at test.com.company.sdk.util.TestSchemaExtractor.testCreateViewToFieldsMap(TestSchemaExtractor.java:48)
First of all, read all the fine print. Note that NHibernate (thus, I assume, Hibernate as well) relational mapping has a funny correspondance with DB and object graph mapping. For example, one-to-one relationships are often implemented as a many-to-one relationship.
Second, before we can tell you how you should write your O/R map, we have to see your DB as well. In particular, can a single Skill be possesses by multiple people? If so, you have a many-to-many relationship; otherwise, it's many-to-one.
Third, I prefer not to implement many-to-many relationships directly, but instead model the "join table" in your domain model--i.e., treat it as an entity, like this:
class PersonSkill
{
Person person;
Skill skill;
}
Then do you see what you have? You have two one-to-many relationships. (In this case, Person may have a collection of PersonSkills, but would not have a collection of Skills.) However, some will prefer to use many-to-many relationship (between Person and Skill); this is controversial.
Fourth, if you do have bidirectional relationships (e.g., not only does Person have a collection of Skills, but also, Skill has a collection of Persons), NHibernate does not enforce bidirectionality in your BL for you; it only understands bidirectionality of the relationships for persistence purposes.
Fifth, many-to-one is much easier to use correctly in NHibernate (and I assume Hibernate) than one-to-many (collection mapping).
Good luck!
I've had the same problem today.
For me, the solution was to go into IIS, right-click on the new Web Site name, select Properties, ASP.Net, and change the ASP.Net version from "1.1.4322" (which it had set as the default) to 2.0.50727.
Once I'd done that, I could right-click on the .svc file, click on "Browse" and see the friendly Service webpage.
You have to set the associatedEmployee on the Vehicle before persisting the Employee.
Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);
newEmployee.setVehicles(vehicles);
Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);
Two solutions: 1- if the type of the target column is [nvarchar] it should be change to [varchar]
2- Add a "Derived Column" component to the SSIS package and add a new column with the following expression:
(DT_WSTR, «length») [ColumnName]
Length is the length of the column in the target table and ColumnName is the name of the column in the target table. finally at the mapping part you should use this new added column instead of the original column.
I like Roy Osherove's naming strategy. It's the following:
[UnitOfWork_StateUnderTest_ExpectedBehavior]
It has every information needed on the method name and in a structured manner.
The unit of work can be as small as a single method, a class, or as large as multiple classes. It should represent all the things that are to be tested in this test case and are under control.
For assemblies, I use the typical .Tests
ending, which I think is quite widespread and the same for classes (ending with Tests
):
[NameOfTheClassUnderTestTests]
Previously, I used Fixture as suffix instead of Tests, but I think the latter is more common, then I changed the naming strategy.
import sys
import time
a = 0
for x in range (0,3):
a = a + 1
b = ("Loading" + "." * a)
# \r prints a carriage return first, so `b` is printed on top of the previous line.
sys.stdout.write('\r'+b)
time.sleep(0.5)
print (a)
Note that you might have to run sys.stdout.flush()
right after sys.stdout.write('\r'+b)
depending on which console you are doing the printing to have the results printed when requested without any buffering.
For Windows you need to do the following:
Windows and type env
Open the edit environment panel
Click Environment Variables
In the system variables section, double click Path
In the dialog, create a System Variable under Path like below ->
MVN_HOME: C:\Users<username>\Documents\Project\Software\apache-maven-3.6.3\bin
Open a new command prompt and hit mvn, you should be able to now.
Wouldn't it be simpler to do this:
sp_help <table_name>
-Click on the 'Column_name' column> Copy> Paste (creates a vertical list) into a New Query window and just type commas in front of each column value... comment out the columns you don't want... far less typing than any code offered here and still manageable.
You need to include the following lines in your docker-compose.yml:
version: "3"
services:
app:
image: app:1.2.3
stdin_open: true # docker run -i
tty: true # docker run -t
The first corresponds to -i
in docker run
and the second to -t
.

I don't know if this applies to JAX-WS, but for JAX-RS I was able to access a file by injecting a ServletContext and then calling getResourceAsStream() on it:
@Context ServletContext servletContext;
...
InputStream is = servletContext.getResourceAsStream("/WEB-INF/test_model.js");
Note that, at least in GlassFish 3.1, the path had to be absolute, i.e., start with slash. More here: How do I use a properties file with jax-rs?
Just multiply the number by 100, round, and divide the resulting number by 100.
A class that will play a WAV file, blocking until the sound has finished playing:
class Sound implements Playable {
private final Path wavPath;
private final CyclicBarrier barrier = new CyclicBarrier(2);

this.wavPath = wavPath;
}
@Override
public void play() throws LineUnavailableException, IOException, UnsupportedAudioFileException {
try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
final Clip clip = AudioSystem.getClip()) {
listenForEndOf(clip);
clip.open(audioIn);
clip.start();
waitForSoundEnd();
}
}
private void listenForEndOf(final Clip clip) {
clip.addLineListener(event -> {
if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();

Labelling the attribute is ideal way. MACRO leads to sometime confusion. and by using void(x),we are adding an overhead in processing.
If not using input argument, use
void foo(int __attribute__((unused))key)
{
}
If not using the variable defined inside the function
void foo(int key)
{
int hash = 0;
int bkt __attribute__((unused)) = 0;
api_call(x, hash, bkt);
}
Now later using the hash variable for your logic but doesn’t need bkt. define bkt as unused, otherwise compiler says'bkt set bt not used".
NOTE: This is just to suppress the warning not for optimization.
your xpath should work . i have tested your xpath and mine in both MarkLogic and Zorba Xquery/ Xpath implementation.
Both should work.
/node/child::text()[1] - should return Text1
/node/child::text()[2] - should return text2
/node/text()[1] - should return Text1
/node/text()[2] - should return text2
I did it with the 'date' function as described in here :
(SELECT count(*) as the-counts,(date(timestamp)) as the-timestamps FROM `user_data` WHERE 1 group BY the-timestamps)
Replace the comma with a dot.
This will only return 554:
var value = parseFloat("554,20")
This will return 554.20:
var value = parseFloat("554.20")
So in the end, you can simply use:
var fValue = parseFloat(document.getElementById("textfield").value.replace(",","."))
Don't forget that parseInt()
should only be used to parse integers (no floating points). In your case it will only return 554. Additionally, calling parseInt() on a float will not round the number: it will take its floor (closest lower integer).
Extended example to answer Pedro Ferreira's question from the comments:
If the textfield contains thousands separator dots like in 1.234.567,99
those could be eliminated beforehand with another replace
:
var fValue = parseFloat(document.getElementById("textfield").value.replace(/\./g,"").replace(",","."))
If you can't use box-sizing (e.g. when you convert HTML to PDF using iText). Try this:
CSS
.input-wrapper { border: 1px solid #ccc; padding: 0 5px; min-height: 20px; }
.input-wrapper input[type=text] { border: none; height: 20px; width: 100%; padding: 0; margin: 0; }
HTML
<div class="input-wrapper">
<input type="text" value="" name="city"/>
</div>
1) Requires .NET framework 4 updated to at least 4.0.2. If you have 4.0.2, then you should have
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2
If you have installed latest VS 2012 chances are that you already have 4.0.2. Just verify first.
2) Next you need to have an instance of LocalDb
. By default you have an instance whose name is a single v
character followed by the LocalDB release version number in the format xx.x. For example, v11.0
represents SQL Server 2012. Automatic instances are public by default. You can also have named instances which are private. Named instances provide isolation from other instances and can improve performance by reducing resource contention with other database users. You can check the status of instances using the SqlLocalDb.exe
utility (run it from command line).
3) Next your connection string should look like:
"Server=(localdb)\\v11.0;Integrated Security=true;"
or
"Data Source=(localdb)\\test;Integrated Security=true;"
from your code. They both are the same. Notice the two \\
required because \v
and \t
means special characters. Also note that what appears after (localdb)\\
is the name of your LocalDb instance. v11.0
is the default public instance, test
is something I have created manually which is private.
If you have a database (.mdf file) already:
"Server=(localdb)\\Test;Integrated Security=true;AttachDbFileName= myDbFile;"
If you don't have a Sql Server database:
"Server=(localdb)\\v11.0;Integrated Security=true;"
And you can create your own database programmatically:
a) to save it in the default location with default setting:
var query = "CREATE DATABASE myDbName;";
b) To save it in a specific location with your own custom settings:
// your db name
string dbName = "myDbName";
// path to your db files:
// ensure that the directory exists and you have read write permission.
string[] files = { Path.Combine(Application.StartupPath, dbName + ".mdf"),
Path.Combine(Application.StartupPath, dbName + ".ldf") };
// db creation query:
// note that the data file and log file have different logical names
var query = "CREATE DATABASE " + dbName +
" ON PRIMARY" +
" (NAME = " + dbName + "_data," +
" FILENAME = '" + files[0] + "'," +
" SIZE = 3MB," +
" MAXSIZE = 10MB," +
" FILEGROWTH = 10%)" +
" LOG ON" +
" (NAME = " + dbName + "_log," +
" FILENAME = '" + files[1] + "'," +
" SIZE = 1MB," +
" MAXSIZE = 5MB," +
" FILEGROWTH = 10%)" +
";";
And execute!
A sample table can be loaded into the database with something like:
@"CREATE TABLE supportContacts
(
id int identity primary key,
type varchar(20),
details varchar(30)
);
INSERT INTO supportContacts
(type, details)
VALUES
('Email', '[email protected]'),
('Twitter', '@sqlfiddle');";
Note that SqlLocalDb.exe
utility doesnt give you access to databases, you separately need sqlcmd
utility which is sad..
EDIT: moved position of semicolon otherwise error would occur if code was copy/pasted
Convert an iterable to a list may have a cost. Instead, to get the the first item, you can use:
next(iter(keys))
Or, if you want to iterate over all items, you can use:
items = iter(keys)
while True:
try:
item = next(items)
except StopIteration as e:
pass # finish
The problem is in the network layer. Here are the status codes explained:
Connection refused
: The peer is not listening on the respective network port you're trying to connect to. This usually means that either a firewall is actively denying the connection or the respective service is not started on the other site or is overloaded.
Connection timed out
: During the attempt to establish the TCP connection, no response came from the other side within a given time limit. In the context of urllib this may also mean that the HTTP response did not arrive in time. This is sometimes also caused by firewalls, sometimes by network congestion or heavy load on the remote (or even local) site.
That said, it is probably not a problem in your script, but on the remote site. If it's occuring occasionally, it indicates that the other site has load problems or the network path to the other site is unreliable.
Also, as it is a problem with the network, you cannot tell what happened on the other side. It is possible that the packets travel fine in the one direction but get dropped (or misrouted) in the other.
It is also not a (direct) DNS problem, that would cause another error (Name or service not known or something similar). It could however be the case that the DNS is configured to return different IP addresses on each request, which would connect you (DNS caching left aside) to different addresses hosts on each connection attempt. It could in turn be the case that some of these hosts are misconfigured or overloaded and thus cause the aforementioned problems.
As suggested in the another answer, using a packet analyzer can help to debug the issue. You won't see much however except the packets reflecting exactly what the error message says.
To rule out network congestion as a problem you could use a tool like mtr
or traceroute
or even ping
to see if packets get lost to the remote site. Note that, if you see loss in mtr (and any traceroute tool for that matter), you must always consider the first host where loss occurs (in the route from yours to remote) as the one dropping packets, due to the way ICMP works. If the packets get lost only at the last hop over a long time (say, 100 packets), that host definetly has an issue. If you see that this behaviour is persistent (over several days), you might want to contact the administrator.
Loss in a middle of the route usually corresponds to network congestion (possibly due to maintenance), and there's nothing you could do about it (except whining at the ISP about missing redundance).
If network congestion is not a problem (i.e. not more than, say, 5% of the packets get lost), you should contact the remote server administrator to figure out what's wrong. He may be able to see relevant infos in system logs. Running a packet analyzer on the remote site might also be more revealing than on the local site. Checking whether the port is open using netstat -tlp
is definetly recommended then.
Currently you are sending the data as typical POST values, which look like this:
first_name=somename&last_name=somesurname
If you want to send data as json you need to create an object with data and stringify it.
data: JSON.stringify(someobject)
Space variants:
<string name="space_demo">| | | |</string>
| SPACE | THIN SPACE | HAIR SPACE |
These 2 will be feel same as first as both are used to say about a condition to filter data. Though we can use ‘having’ in place of ‘where’ in any case, there are instances when we can’t use ‘where’ instead of ‘having’. This is because in a select query, ‘where’ filters data before ‘select’ while ‘having’ filter data after ‘select’. So, when we use alias names that are not actually in the database, ‘where’ can’t identify them but ‘having’ can.
Ex: let the table Student contain student_id,name, birthday,address.Assume birthday is of type date.
SELECT * FROM Student WHERE YEAR(birthday)>1993; /*this will work as birthday is in database.if we use having in place of where too this will work*/
SELECT student_id,(YEAR(CurDate())-YEAR(birthday)) AS Age FROM Student HAVING Age>20;
/*this will not work if we use ‘where’ here, ‘where’ don’t know about age as age is defined in select part.*/
You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.
e.g.
class App extends React.Component {
componentDidMount() {
// Jquery here $(...)...
}
// ...
}
Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.
class Accordion extends React.Component {
constructor() {
super();
this._handleClick = this._handleClick.bind(this);
}
componentDidMount() {
this._handleClick();
}
_handleClick() {
const acc = this._acc.children;
for (let i = 0; i < acc.length; i++) {
let a = acc[i];
a.onclick = () => a.classList.toggle("active");
}
}
render() {
return (
<div
ref={a => this._acc = a}
onClick={this._handleClick}>
{this.props.children}
</div>
)
}
}
Then you can use it in any component like so:
class App extends React.Component {
render() {
return (
<div>
<Accordion>
<div className="accor">
<div className="head">Head 1</div>
<div className="body"></div>
</div>
</Accordion>
</div>
);
}
}

The other answers so far create new commits that undo what is in older commits. It is possible to go back and "change history" as it were, but this can be a bit dangerous. You should only do this if the commit you're changing has not been pushed to other repositories.
The command you're looking for is git rebase --interactive
If you want to change HEAD~3, the command you want to issue is git rebase --interactive HEAD~4
. This will open a text editor and allow you to specify which commits you want to change.
Practice on a different repository before you try this with something important. The man pages should give you all the rest of the information you need.
This is what I came up with:
$(document).ready(function(){_x000D_
_x000D_
$(".fc-event").each(function(){_x000D_

console.log(this.attributes['data'].nodeValue) _x000D_
});_x000D_
_x000D_
});
_x000D_

This can be done with CSS3:
<input type="text" />
input
{
-moz-border-radius: 15px;
border-radius: 15px;
border:solid 1px black;
padding:5px;
}
However, an alternative would be to put the input
inside a div
with a rounded background, and no border on the input
Ed McManus has certainly provided a key to getting this to work. I found a case that does not work

rect will not have the correct height. Notice that anotherString (which is appended to string) was initialized without an attribute dictionary. This is a legitimate initializer for anotherString but boundingRectWithSize: does not give an accurate size in this case.
You want to replace the values in a dataset column, but you're getting an error like this:
invalid factor level, NA generated
Try this instead:
levels(dataframe$column)[levels(dataframe$column)=='old_value'] <- 'new_value'
This shows, why it is important to "Refer to objects by their interfaces" as described in Effective Java book.
If you code to the implementation and use ArrayList in let's say, 50 places in your code, when you find a good "List" implementation that count the items, you will have to change all those 50 places, and probably you'll have to break your code ( if it is only used by you there is not a big deal, but if it is used by someone else uses, you'll break their code too)
By programming to the interface you can let those 50 places unchanged and replace the implementation from ArrayList to "CountItemsList" (for instance ) or some other class.
Below is a very basic sample on how this could be written. This is only a sample, a production ready List would be much more complicated.
import java.util.*;
public class CountItemsList<E> extends ArrayList<E> {
// This is private. It is not visible from outside.
private Map<E,Integer> count = new HashMap<E,Integer>();
// There are several entry points to this class
// this is just to show one of them.
public boolean add( E element ) {
if( !count.containsKey( element ) ){
count.put( element, 1 );
} else {
count.put( element, count.get( element ) + 1 );
}
return super.add( element );
}
// This method belongs to CountItemList interface ( or class )
// to used you have to cast.
public int getCount( E element ) {
if( ! count.containsKey( element ) ) {
return 0;
}
return count.get( element );
}
public static void main( String [] args ) {
List<String> animals = new CountItemsList<String>();
animals.add("bat");
animals.add("owl");
animals.add("bat");
animals.add("bat");
System.out.println( (( CountItemsList<String> )animals).getCount( "bat" ));
}
}

You need to set figure
properties.
At the very beginning of the script, call
figure('name','something else')
Calling figure
is a good thing, anyway, because without it, you always plot into the same window, and sometimes you may want to compare two windows side-by-side.
Alternatively, you can store the figure's handle by calling
figH = figure;
so that you can later change the figure properties to your liking (the 'numberTitle'
property setting eliminates the "figure X" text)
set(figH,'Name','something else','NumberTitle','off')
Have a look at the figure properties in the MATLAB documentation to see what else you can change if you want.
Does it open correctly when you run "explorer.exe c:\teste" from your start menu? How long have you been trying this? I see a similar behavior when my machine has a lot of processes and when I open a new process(sets say IE)..it starts in the task manager but does not show up in the front end. Have you tried a restart?
The following code should open a new explorer instance
class sample{
static void Main()
{
System.Diagnostics.Process.Start("explorer.exe",@"c:\teste");
}
}
Gravity: Allow you move the content inside a container. (How sub-views will be placed).
Important: (MOVE along X-axis or Y-axis within available space).
Example: Let's say if you were to work with LinearLayout (Height: match_parent, Width: match_parent) as root level element, then you will have full frame space available; and the child views says 2 TextViews (Height: wrap_content, Width: wrap_content) inside the LinearLayout can be moved around along x/y axis using corresponding values for gravity on parent.
Layout_Gravity: Allow you to override the parent gravity behavior ONLY along x-axis.
Important: (MOVE[override] along X-axis within available space).
Example: If you keep in mind the previous example, we know gravity enabled us to move along x/y axis, i.e; the place TextViews inside LinearLayout. Let's just say LinearLayout specifies gravity: center; meaning every TextView needs to be center both vertically and horizontally. Now if we want one of the TextView to go left/right, we can override the specified gravity behavior using layout_gravity on the TextView.
Bonus: if you dig deeper, you will find out that text within the TextView act as sub-view; so if you apply the gravity on TextView, the text inside the TextView will move around. (the entire concept apply here too)

To create circles
new BoxDecoration(

? new DecorationImage(image: backgroundImage, fit: BoxFit.cover)

and https://docs.flutter.io/flutter/widgets/Transform/Transform.rotate.html to position the white dots.
Through the this steps you can .
1.
To_Date(To_Char(MaxDate, 'DD/MM/YYYY')) = REP_DATE
is causing the issue. when you use to_date without the time format, oracle will use the current sessions NLS format to convert, which in your case might not be "DD/MM/YYYY". Check this...
SQL> select sysdate from dual;
SYSDATE
---------
26-SEP-12
Which means my session's setting is DD-Mon-YY
SQL> select to_char(sysdate,'MM/DD/YYYY') from dual;
TO_CHAR(SY
----------
09/26/2012
SQL> select to_date(to_char(sysdate,'MM/DD/YYYY')) from dual;
select to_date(to_char(sysdate,'MM/DD/YYYY')) from dual
*
ERROR at line 1:
ORA-01843: not a valid month
SQL> select to_date(to_char(sysdate,'MM/DD/YYYY'),'MM/DD/YYYY') from dual;
TO_DATE(T
---------
26-SEP-12
2.
More importantly, Why are you converting to char and then to date, instead of directly comparing
MaxDate = REP_DATE
If you want to ignore the time component in MaxDate before comparision, you should use..
trunc(MaxDate ) = rep_date
instead.
==Update : based on updated question.
Rep_Date = 01/04/2009 Rep_Time = 01/01/1753 13:00:00
I think the problem is more complex. if rep_time is intended to be only time, then you cannot store it in the database as a date. It would have to be a string or date to time interval or numerically as seconds (thanks to Alex, see this) . If possible, I would suggest using one column rep_date that has both the date and time and compare it to the max date column directly.
If it is a running system and you have no control over repdate, you could try this.
trunc(rep_date) = trunc(maxdate) and
to_char(rep_date,'HH24:MI:SS') = to_char(maxdate,'HH24:MI:SS')
Either way, the time is being stored incorrectly (as you can tell from the year 1753) and there could be other issues going forward.
Supose you have the following scenario:
* 1bd2200 (HEAD, master) another commit
* d258546 bad commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit
Where you want to remove d258546 i.e. "bad commit".
You shall try an interactive rebase to remove it: git rebase -i 34c4f95
then your default editor will pop with something like this:
pick bd8aa13 2nd commit
pick 0f1efa9 3rd commit
pick d258546 bad commit
pick 1bd2200 another commit
# Rebase 34c4f95..1bd2200 onto 34c4f95
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
just remove the line with the commit you want to strip and save+exit the editor:
pick bd8aa13 2nd commit
pick 0f1efa9 3rd commit
pick 1bd2200 another commit
...
git will proceed to remove this commit from your history leaving something like this (mind the hash change in the commits descendant from the removed commit):
* 34fa994 (HEAD, master) another commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit
Now, since I suppose that you already pushed the bad commit to gitlab, you'll need to repush your graph to the repository (but with the -f
option to prevent it from being rejected due to a non fastforwardeable history i.e. git push -f <your remote> <your branch>
)
Please be extra careful and make sure that none coworker is already using the history containing the "bad commit" in their branches.
Alternative option:
Instead of rewrite the history, you may simply create a new commit which negates the changes introduced by your bad commit, to do this just type git revert <your bad commit hash>
. This option is maybe not as clean, but is far more safe (in case you are not fully aware of what are you doing with an interactive rebase).
The virtual keyword is used to modify a method, property, indexer, or event declaration and allow for it to be overridden in a derived class. For example, this method can be overridden by any class that inherits it:
public virtual double Area()
{
return x * y;
}
You cannot use the virtual modifier with the static, abstract, private, or override modifiers. The following example shows a virtual property:
class MyBaseClass
{
// virtual auto-implemented property. Overrides can only
// provide specialized behavior if they implement get and set accessors.
public virtual string Name { get; set; }
// ordinary virtual property with backing field
private int num;
public virtual int Number
{
get { return num; }
set { num = value; }
}
}
class MyDerivedClass : MyBaseClass
{
private string name;
// Override auto-implemented property with ordinary property
// to provide specialized accessor behavior.
public override string Name
{
get
{
return name;
}
set
{
if (value != String.Empty)
{
name = value;
}
else
{
name = "Unknown";
}
}
}
}
Add http:// in front of url
Incorrect
<a href="www.example.com">www.example.com</span></p>
Correct
<a href="http://www.example.com">www.example.com</span></p>
I would say to set up the font size change in your CSS stylesheet file.
I'm pretty sure that you want all text at the same size for all your form fields. Adding inline styles in your HTML will add to many lines at the end... plus you would need to add it to the other types of form fields such as <select>
.
HTML:
<div id="cForm">
<form method="post">
<input type="text" name="name" placeholder="Name" data-required="true">
<option value="" selected="selected" >Choose Category...</option>
</form>
</div>
CSS:
input, select {
font-size: 18px;
}
I struggled with this for a couple of hours, so I would like to add some clarifications for it, all the examples noted here, refers to cases where the data is loaded from the script itself, not something coming from a service or a database, so I would like to provide my experience for anyone having the same problem as I did.
Normally you save only the id of the desired option in your database, so... let's show it
service.js
myApp.factory('Models', function($http) {
var models = {};
models.allModels = function(options) {
return $http.post(url_service, {options: options});
};
return models;
});
controller.js
myApp.controller('exampleController', function($scope, Models) {
$scope.mainObj={id_main: 1, id_model: 101};
$scope.selected_model = $scope.mainObj.id_model;
Models.allModels({}).success(function(data) {
$scope.models = data;
});
});
Finally the partial html model.html
Model: <select ng-model="selected_model"
ng-options="model.id_model as model.name for model in models" ></select>
basically I wanted to point that piece "model.id_model as model.name for model in models" the "model.id_model" uses the id of the model for the value so that you can match with the "mainObj.id_model" which is also the "selected_model", this is just a plain value, also "as model.name" is the label for the repeater, finally "model in models" is just the regular cycle that we all know about.
Hope this helps somebody, and if it does, please vote up :D
No my friend its very simple, try using this:
AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
alertDialog.setTitle("Alert Dialog");
alertDialog.setMessage("Welcome to dear user.");
alertDialog.setIcon(R.drawable.welcome);
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
}
});
alertDialog.show();
This tutorial shows how you can create custom dialog using xml and then show them as an alert dialog.

I don't mention basics like syntax highlighting as I expect these by default.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?
We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments
So, the way the constructors and destructors work is that the shared object file contains special sections (.ctors and .dtors on ELF) which contain references to the functions marked with the constructor and destructor attributes, respectively. When the library is loaded/unloaded the dynamic loader program (ld.so or somesuch) checks whether such sections exist, and if so, calls the functions referenced therein.
Come to think of it, there is probably some similar magic in the normal static linker so that the same code is run on startup/shutdown regardless if the user chooses static or dynamic linking.
I have tried almost every obfuscator on the market and SmartAssembly is the best in my opinion.
The primary flag seems to only work for vagrant ssh
for me.
In the past I have used the following method to hack around the issue.
# stage box intended for configuration closely matching production if ARGV[1] == 'stage' config.vm.define "stage" do |stage| box_setup stage, \ "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml" end end
But, setting only that parameters, the authentication don't works.
Are necessary to add to that code the following:
final String authUser = "myuser";
final String authPassword = "secret";
System.setProperty("http.proxyHost", "hostAddress");
System.setProperty("http.proxyPort", "portNumber");
System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);
Authenticator.setDefault(
new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(authUser, authPassword.toCharArray());
}
}
);
Here is the code to handle custom error message in HTML5:
<input type="text" id="username" required placeholder="Enter Name"
oninvalid="this.setCustomValidity('Enter User Name Here')"
oninput="this.setCustomValidity('')"/>
This part is important because it hides the error message when the user inputs new data:
oninput="this.setCustomValidity('')"
If you're using GNU find
, you can try -execdir
parameter, e.g.:
find . -type d -execdir realpath "{}" ';'
or (as per @gniourf_gniourf comment):
find . -type d -execdir sh -c 'printf "%s/%s\n" "$PWD" "$0"' {} \;
Note: You can use ${0#./}
instead of $0
to fix ./
in the front.
or more practical example:
find . -name .git -type d -execdir git pull -v ';'
If you want to include the current directory, it's even simpler by using -exec
:
find . -type d -exec sh -c 'cd -P -- "{}" && pwd -P' \;
or using xargs
:
find . -type d -print0 | xargs -0 -L1 sh -c 'cd "$0" && pwd && echo Do stuff'
Or similar example suggested by @gniourf_gniourf:
find . -type d -print0 | while IFS= read -r -d '' file; do
# ...
done
The above examples support directories with spaces in their name.
Or by assigning into bash array:
dirs=($(find . -type d))
for dir in "${dirs[@]}"; do
cd "$dir"
echo $PWD
done
Change .
to your specific folder name. If you don't need to run recursively, you can use: dirs=(*)
instead. The above example doesn't support directories with spaces in the name.
So as @gniourf_gniourf suggested, the only proper way to put the output of find in an array without using an explicit loop will be available in Bash 4.4 with:
mapfile -t -d '' dirs < <(find . -type d -print0)
Or not a recommended way (which involves parsing of ls
):
ls -d */ | awk '{print $NF}' | xargs -n1 sh -c 'cd $0 && pwd && echo Do stuff'
The above example would ignore the current dir (as requested by OP), but it'll break on names with the spaces.

I tried several solutions and here is the simplest I personally found.
Dan pointed out in the comments that the original post belongs to Oleg Sych—thanks, Oleg!
Here are the instructions:
1. Add an XML file for each configuration to the project.
Typically you will have Debug
and Release
configurations so name your files App.Debug.config
and App.Release.config
. In my project, I created a configuration for each kind of environment, so you might want to experiment with that.
2. Unload project and open .csproj file for editing
Visual Studio allows you to edit .csproj files right in the editor—you just need to unload the project first. Then right-click on it and select Edit <ProjectName>.csproj.
3. Bind App.*.config files to main App.config
Find the project file section that contains all App.config
and App.*.config
references. You'll notice their build actions are set to None
:
<None Include="App.config" />
<None Include="App.Debug.config" />
<None Include="App.Release.config" />
First, set build action for all of them to Content
.
Next, make all configuration-specific files dependant on the main App.config
so Visual Studio groups them like it does designer and code-behind files.
Replace XML above with the one below:
<Content Include="App.config" />
<Content Include="App.Debug.config" >
<DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config" >
<DependentUpon>App.config</DependentUpon>
</Content>
4. Activate transformations magic (only necessary for Visual Studio versions pre VS2017)
In the end of file after
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
and before final
</Project>
insert the following XML:

Sometime ago I implemented an easy to use "download manager" library: PTDownloadManager. You could give it a shot!
Yes, buffering should be used for better performance. Use BufferedReader OR byte[] to store your temp data.
thanks.
The question was to see if ping responded which this script does.
However this will not work if you get the Host Unreachable message as this returns ERRORLEVEL 0 and passes the check for Received = 1 used in this script, returning Link is UP from the script. Host Unreachable occurs when ping was delivered to target notwork but remote host cannot be found.
If I recall the correct way to check if ping was successful is to look for the string 'TTL' using Find.
@echo off
cls
set ip=%1
ping -n 1 %ip% | find "TTL"
if not errorlevel 1 set error=win
if errorlevel 1 set error=fail
cls
echo Result: %error%
This wont work with IPv6 networks because ping will not list TTL when receiving reply from IPv6 address.
I hit the same shared memory realm does not exist
symptom (on Windows) but for a different reason. I had just installed Oracle (XE) and after some troubleshooting, established that my installation was corrupt due to the presence of an ORACLE_HOME environment property at the time I installed it.
If this is TLDR, skip to 'So to resolve:'!
My initial symptom was:
Message 850 not found; No message file for product=NETWORK, facility=NL
Apparently the Windows install reads the ORACLE_HOME from the registry and doesn't need (and certainly in my case shouldn't have...) an environment property.
Remove it, as follows:
Following the restart I was then able to get error messages other than 'No message file...' and could start looking at what the issue was. Setting the ORACLE_SID to XE and connecting @XE I got as far as the errors in this page, namely the following symptoms:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Another symptom was: When launching the 'Get started' page it failed to connect, giving a not found error (if I recall correctly), despite the Windows listener & XE services being started. As noted in another answer, this could be due to the windows services not being started. In my case those services were started, so something else was misconfigured.
At this point, I figured maybe my install had just gone so badly wrong due to the presence of my bad ORACLE_HOME environment property that I should reinstall. (Previous reinstalls hadn't helped, but those had all been before I noticed the ORACLE_HOME system environment property (probably set up by me a year ago!).
So to resolve:
Task.WaitAll
blocks the current thread until everything has completed.
Task.WhenAll
returns a task which represents the action of waiting until everything has completed.
That means that from an async method, you can use:
await Task.WhenAll(tasks);
... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.
Just open that C:/Sites/folder/Pids/Server.pids and copy that 4 digit value.that 4 digit value is nothing but a PID, which you need to kill to stop the already running process.
then to stop the process use below command
kill -9 <pid>
once that already running process get stopped then hit
rails s

Create in your Site.css (or in another place) a new class named for example .font-bold and set it to your element
.font-bold {
font-weight: bold;
}
For typescript you can specify generic param of your empty observable like this:
import 'rxjs/add/observable/empty'
Observable.empty<Response>();
I had copy pasted my inline js
from some other .php
project, inside that block of code there was some php
code outputting some value, now since the variable wasn't defined in my new file, it was producing the typical php
undefined warning/error
, and because of that the js
code was being messed up, and wasn't responding to any event, even alert("xyz");
would fail silently!! Although the erronous line was way near the end of the file, still the js
would just die that too,
without any errors!!! >:(
Now one thing confusing is that debugger console/output gave no hint/error/warning whatsoever, the js
was dying silently.
So try checking if you have php
inline coded with the js
, and see if it is outputting any error. Once removed/sorted your js
should work fine.
Click on servers tab in eclipse and then double click on the server listed there. Select the port tab in the config page opened.Change the port to any other ports.Restart the server.

Solution:
SUBSTRING(sys.fn_sqlvarbasetostr(HASHBYTES('MD5','your text')),3,32)
as of 12.03.2019 FusionTables is no more...
Import the Shapefile into Google FusionTables ( http://www.google.com/fusiontables ) using http://www.shpescape.com/ and from there you can use the data in a number of ways, eg. display it using GoogleMaps.
You could use unions to create structs like the following, which contains a field that tells us which component of the union is actually used:
struct VAROBJECT
{
enum o_t { Int, Double, String } objectType;
union
{
int intValue;
double dblValue;
char *strValue;
} value;
} object;
I think this is what you want:
/grand/parent/child[@id="#grand"]
server.session.timeout
in the application.properties
file is now deprecated. The correct setting is:
server.servlet.session.timeout=60s
Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.
a ||= b
evaluates the same way as each of the following lines
a || a = b
a ? a : a = b
if a then a else a = b end
-
On the other hand,
a = a || b
evaluates the same way as each of the following lines
a = a ? a : b
if a then a = a else a = b end
-
Edit: As AJedi32 pointed out in the comments, this only holds true if: 1. a is a defined variable. 2. Evaluating a one time and two times does not result in a difference in program or system state.
You need to use the option -f
:
$ grep -f A B
The option -F
does a fixed string search where as -f
is for specifying a file of patterns. You may want both if the file only contains fixed strings and not regexps.
$ grep -Ff A B
You may also want the -w
option for matching whole words only:
$ grep -wFf A B
Read man grep
for a description of all the possible arguments and what they do.
This is confusing for everyone when it comes IISExpress. There is nothing to read console messages. So for example, in the ASPCORE MVC apps it configures using appsettings.json which does nothing if you are using IISExpress.
For right now you can just add loggerFactory.AddDebug(LogLevel.Debug); in your Configure section and it will at least show you your logs in the Debug Output window.
Good news CORE 2.0 this will all be changing: https://github.com/aspnet/Announcements/issues/255
Ultimately they both produce the same HTML but Html.TextBoxFor() is strongly typed where as Html.TextBox isn't.
1: @Html.TextBox("Name")
2: Html.TextBoxFor(m => m.Name)
will both produce
<input id="Name" name="Name" type="text" />
So what does that mean in terms of use?
Generally two things:
TextBoxFor
will generate your input names for you. This is usually just the property name but for properties of complex types can include an underscore such as 'customer_name'TextBoxFor
version will allow you to use compile time checking. So if you change your model then you can check whether there are any errors in your views.It is generally regarded as better practice to use the strongly typed versions of the HtmlHelpers that were added in MVC2.
XAMPP by default uses http://localhost/phpmyadmin
It also requires you start both Apache and MySQL from the control panel (or as a service).
In the XAMPP Control Panel, clicking [ Admin ] on the MySQL line will open your default browser at the configured URL for the phpMyAdmin application.
If you get a phpMyAdmin error stating "Cannot connect: invalid settings." You will need to make sure your MySQL config file has a matching port for server and client. If it is not the standard 3306 port, you will also need to change your phpMyAdmin config file under apache (config.inc.php) to meet the new port settings. (127.0.0.1 becomes 127.0.0.1:<port>)
split($pattern,$string)
split strings within a given pattern or regex (it's deprecated since 5.3.0)
preg_split($pattern,$string)
split strings within a given regex pattern
explode($pattern,$string)
split strings within a given pattern
end($arr)
get last array element
So:
end(split('-',$str))
end(preg_split('/-/',$str))
$strArray = explode('-',$str)
$lastElement = end($strArray)
Will return the last element of a -
separated string.
And there's a hardcore way to do this:
$str = '1-2-3-4-5';
echo substr($str, strrpos($str, '-') + 1);
// | '--- get the last position of '-' and add 1(if don't substr will get '-' too)
// '----- get the last piece of string after the last occurrence of '-'
MySQL's Spatial Extensions are the best option because you have the full list of spatial operators and indices at your disposal. A spatial index will allow you to perform distance-based calculations very quickly. Please keep in mind that as of 6.0, the Spatial Extension is still incomplete. I am not putting down MySQL Spatial, only letting you know of the pitfalls before you get too far along on this.
If you are dealing strictly with points and only the DISTANCE function, this is fine. If you need to do any calculations with Polygons, Lines, or Buffered-Points, the spatial operators do not provide exact results unless you use the "relate" operator. See the warning at the top of 21.5.6. Relationships such as contains, within, or intersects are using the MBR, not the exact geometry shape (i.e. an Ellipse is treated like a Rectangle).
Also, the distances in MySQL Spatial are in the same units as your first geometry. This means if you're using Decimal Degrees, then your distance measurements are in Decimal Degrees. This will make it very difficult to get exact results as you get furthur from the equator.
This will give DISTINCT values across all the columns:
SELECT DISTINCT value
FROM (
SELECT DISTINCT a AS value FROM my_table
UNION SELECT DISTINCT b AS value FROM my_table
UNION SELECT DISTINCT c AS value FROM my_table
) AS derived
Just one more idea to detect:
DebugMode.h
#import <Foundation/Foundation.h>
@interface DebugMode: NSObject
+(BOOL) isDebug;
@end
DebugMode.m
#import "DebugMode.h"
@implementation DebugMode
+(BOOL) isDebug {
#ifdef DEBUG
return true;
#else
return false;
#endif
}
@end
add into header bridge file:
#include "DebugMode.h"
usage:
DebugMode.isDebug()
It is not needed to write something inside project properties swift flags.
I've found the solution :
You have to add the html5=1
in the src attribute of the iframe :
<iframe src="http://www.youtube.com/embed/dP15zlyra3c?html5=1"></iframe>
The video will be displayed as HTML5 if available, or fallback into flash player.
Turn it around by doing:
<style type="text/css">
#middlecol {
border-right: 2px solid red;
width: 45%;
}
#middlecol table {
max-width: 400px;
width: 100% !important;
}
</style>
Also I would advise you to:
center
tag (it's deprecated)width
, bgcolor
attributes, set them by CSS (width
and background-color
)(assuming that you can control the table that was rendered)
You need something like this:
foreach(DataColumn c in dr.Table.Columns)
{
MessageBox.Show(c.ColumnName);
}
You can check the type of your variable whether it is an array with;
var myArray=[];
if(myArray instanceof Array)
{
....
}
Create a TXT file on your desktop named "xls2csv.vbs" and paste the code:
Dim vExcel
Dim vCSV
Set vExcel = CreateObject("Excel.Application")
Set vCSV = vExcel.Workbooks.Open(Wscript.Arguments.Item(0))
vCSV.SaveAs WScript.Arguments.Item(0) & ".csv", 6
vCSV.Close False
vExcel.Quit
Drag a XLS file to it (like "test.xls"). It will create a converted CSV file named "test.xls.csv". Then, rename it to "test.csv". Done.
Monkey is right, according to the link given by monkey
Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.
I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting
Depends on your use case.
If you want to do some animation of children blending in, use the react animation add-on: https://facebook.github.io/react/docs/animation.html Otherwise, make the rendering of the children dependent on props and add the props after some delay.
I wouldn't delay in the component, because it will probably haunt you during testing. And ideally, components should be pure.
You can use:
$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);
Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.
You can use:
const sha1 = require('sha1');
const crypt = sha1('Text');
console.log(crypt);
For install:
sudo npm install -g sha1
npm install sha1 --save
This problem was caused by building my project in the Release schema. It can be caused by other things as well. Try to switch the build schema by going in xCode to Product > Scheme > Edit Scheme. In the "Run" Section located on the left, switch the "Build Configuration" to "Debug". I hope this will help.
This problem normally appears while copy pasting the tag lib URL from the internet. Usually the quotes ""
in which the URL http://www.springframework.org/tags is embedded might not be correct. Try removing quotes and type them manually. This resolved the issue for me.
The fastest MySQL
solution, without inner queries and without GROUP BY
:
SELECT m.* -- get the row that contains the max value
FROM topten m -- "m" from "max"
LEFT JOIN topten b -- "b" from "bigger"
ON m.home = b.home -- match "max" row with "bigger" row by `home`
AND m.datetime < b.datetime -- want "bigger" than "max"
WHERE b.datetime IS NULL -- keep only if there is no bigger than max
Explanation:
Join the table with itself using the home
column. The use of LEFT JOIN
ensures all the rows from table m
appear in the result set. Those that don't have a match in table b
will have NULL
s for the columns of b
.
The other condition on the JOIN
asks to match only the rows from b
that have bigger value on the datetime
column than the row from m
.
Using the data posted in the question, the LEFT JOIN
will produce this pairs:
+------------------------------------------+--------------------------------+
| the row from `m` | the matching row from `b` |
|------------------------------------------|--------------------------------|
| id home datetime player resource | id home datetime ... |
|----|-----|------------|--------|---------|------|------|------------|-----|
| 1 | 10 | 04/03/2009 | john | 399 | NULL | NULL | NULL | ... | *
| 2 | 11 | 04/03/2009 | juliet | 244 | NULL | NULL | NULL | ... | *
| 5 | 12 | 04/03/2009 | borat | 555 | NULL | NULL | NULL | ... | *
| 3 | 10 | 03/03/2009 | john | 300 | 1 | 10 | 04/03/2009 | ... |
| 4 | 11 | 03/03/2009 | juliet | 200 | 2 | 11 | 04/03/2009 | ... |
| 6 | 12 | 03/03/2009 | borat | 500 | 5 | 12 | 04/03/2009 | ... |
| 7 | 13 | 24/12/2008 | borat | 600 | 8 | 13 | 01/01/2009 | ... |
| 8 | 13 | 01/01/2009 | borat | 700 | NULL | NULL | NULL | ... | *
+------------------------------------------+--------------------------------+
Finally, the WHERE
clause keeps only the pairs that have NULL
s in the columns of b
(they are marked with *
in the table above); this means, due to the second condition from the JOIN
clause, the row selected from m
has the biggest value in column datetime
.

without the -webkit-

This tells sed
to delete every line matching the regex ^$
i.e. every empty line. The -i
flag edits the file in-place, if your sed
doesn't support that you can write the output to a temporary file and replace the original:
sed '/^$/d' foo > foo.tmp
mv foo.tmp foo
If you also want to remove lines consisting only of whitespace (not just empty lines) then use:
sed -i '/^[[:space:]]*$/d' foo
Edit: also remove whitespace at the end of lines, because apparently you've decided you need that too:
sed -i '/^[[:space:]]*$/d;s/[[:space:]]*$//' foo

I am doing about the same thing, and here's what I did.
I used separate tables for name, address, email, and numbers, each with a NameID column that is a foreign key on everything except the Name table, on which it is the primary clustered key. I used MainName and FirstName instead of LastName and FirstName to allow for business entries as well as personal entries, but you may not have a need for that.
The NameID column gets to be a smallint in all the tables because I'm fairly certain I won't make more than 32000 entries. Almost everything else is varchar(n) ranging from 20 to 200, depending on what you wanna store (Birthdays, comments, emails, really long names). That is really dependent on what kind of stuff you're storing.
The Numbers table is where I deviate from that. I set it up to have five columns labeled NameID, Phone#, CountryCode, Extension, and PhoneType. I already discussed NameID. Phone# is varchar(12) with a check constraint looking something like this: CHECK (Phone# like '[0-9][0-9][0-9]-[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]'). This ensures that only what I want makes it into the database and the data stays very consistent. The extension and country codes I called nullable smallints, but those could be varchar if you wanted to. PhoneType is varchar(20) and is not nullable.
Hope this helps!

Of course you can use multiple versions of Java under Windows. And different applications can use different Java versions. How is your application started? Usually you will have a batch file where there is something like
java ...
This will search the Java executable using the PATH variable. So if Java 5 is first on the PATH, you will have problems running a Java 6 application. You should then modify the batch file to use a certain Java version e.g. by defining a environment variable JAVA6HOME
with the value C:\java\java6
(if Java 6 is installed in this directory) and change the batch file calling
%JAVA6HOME%\bin\java ...

I printed form javascript to a Star Micronics Webprnt TSP 654ii thermal printer. This printer is a wired network printer and you can draw the content to a HTML canvas and make a HTTP request to print. The only caveat is that, this printer does not support HTTPS protocol yet, so you will get a mixed content warning in production. Contacted Star micronics support and they said, they are working on HTTPS support and soon a firmware upgrade will be available. Also, looks like Epson Omnilink TM-88V printer with TM-I will support javascript printing.

I started reading David Mertz's book today 'Text Processing in Python.' While he has a fairly terse description of Lambda's the examples in the first chapter combined with the explanation in Appendix A made them jump off the page for me (finally) and all of a sudden I understood their value. That is not to say his explanation will work for you and I am still at the discovery stage so I will not attempt to add to these responses other than the following: I am new to Python I am new to OOP Lambdas were a struggle for me Now that I read Mertz, I think I get them and I see them as very useful as I think they allow a cleaner approach to programming.
He reproduces the Zen of Python, one line of which is Simple is better than complex. As a non-OOP programmer reading code with lambdas (and until last week list comprehensions) I have thought-This is simple?. I finally realized today that actually these features make the code much more readable, and understandable than the alternative-which is invariably a loop of some sort. I also realized that like financial statements-Python was not designed for the novice user, rather it is designed for the user that wants to get educated. I can't believe how powerful this language is. When it dawned on me (finally) the purpose and value of lambdas I wanted to rip up about 30 programs and start over putting in lambdas where appropriate.
I'd recommend using some work queue using, for example, the excellent Gearman, which will provide you with a great way to dispatch background jobs, and asynchronously get their result once they're processed.
The advantage of this, used heavily at Digg (among many others) is that it provides a strong, scalable and robust way to make workers in any language to speak with clients in any language.
performance wise, my (crude) measurements found no difference on 1000 writes and reads

Encode or decode byte arrays:
byte[] encoded = Base64.getEncoder().encode("Hello".getBytes());
println(new String(encoded)); // Outputs "SGVsbG8="
byte[] decoded = Base64.getDecoder().decode(encoded);
println(new String(decoded)) // Outputs "Hello"
Or if you just want the strings:
String encoded = Base64.getEncoder().encodeToString("Hello".getBytes());
println(encoded); // Outputs "SGVsbG8="
String decoded = new String(Base64.getDecoder().decode(encoded.getBytes()));
println(decoded) // Outputs "Hello"
For more info, see Base64.
Base64 is not bundled with Java versions less than 8. I recommend using Apache Commons Codec.
For direct byte arrays:
Base64 codec = new Base64();
byte[] encoded = codec.encode("Hello".getBytes());
println(new String(encoded)); // Outputs "SGVsbG8="
byte[] decoded = codec.decode(encoded);
println(new String(decoded)) // Outputs "Hello"
Or if you just want the strings:
Base64 codec = new Base64();
String encoded = codec.encodeBase64String("Hello".getBytes());
println(encoded); // Outputs "SGVsbG8="
String decoded = new String(codec.decodeBase64(encoded));
println(decoded) // Outputs "Hello"
If you're working in a Spring project already, you may find their org.springframework.util.Base64Utils
class more ergonomic:
For direct byte arrays:
byte[] encoded = Base64Utils.encode("Hello".getBytes());
println(new String(encoded)) // Outputs "SGVsbG8="
byte[] decoded = Base64Utils.decode(encoded);
println(new String(decoded)) // Outputs "Hello"
Or if you just want the strings:
String encoded = Base64Utils.encodeToString("Hello".getBytes());
println(encoded); // Outputs "SGVsbG8="
String decoded = Base64Utils.decodeFromString(encoded);
println(new String(decoded)) // Outputs "Hello"
If you are using the Android SDK before Java 8 then your best option is to use the bundled android.util.Base64
.
For direct byte arrays:
byte[] encoded = Base64.encode("Hello".getBytes());
println(new String(encoded)) // Outputs "SGVsbG8="
byte [] decoded = Base64.decode(encoded);
println(new String(decoded)) // Outputs "Hello"
Or if you just want the strings:
String encoded = Base64.encodeToString("Hello".getBytes());
println(encoded); // Outputs "SGVsbG8="
String decoded = new String(Base64.decode(encoded));
println(decoded) // Outputs "Hello"

One of the reasons for this error is when repositoryId is not specified or specified incorrectly. As mentioned already it should be the same as in section in settings.xml. Couple of hints... Run mvn with -e -X options and check the debug output. It will tell you which repositoryId it is using:
[DEBUG] (f) offline = false
[DEBUG] (f) packaging = exe
[DEBUG] (f) pomFile = c:\temp\build-test\pom.xml
[DEBUG] (f) project = MavenProject: org.apache.maven:standalone-pom:1 @
[DEBUG] (f) repositoryId = remote-repository
[DEBUG] (f) repositoryLayout = default
[DEBUG] (f) retryFailedDeploymentCount = 1
[DEBUG] (f) uniqueVersion = true
[DEBUG] (f) updateReleaseInfo = false
[DEBUG] (f) url = https://nexus.url.blah.com/...
[DEBUG] (f) version = 13.1
[DEBUG] -- end configuration --
In this case it uses the default value "remote-repository", which means that something went wrong.
Apparently I have specified -DrepositoryID (note ID in capital) instead of -DrepositoryId.
In addition to Biff MaGriff's answer. To export the file using JQuery, redirect the user to a new page.
$('#btn_export').click(function () {
window.location.href = 'NewsLetter/Export';
});
Warning: This might inflate executable file size a little bit and cost a little runtime performance. IMO, this would be better if golang has such feature like macro or function decorator.
If you want to mock functions without changing its API, the easiest way is to change the implementation a little bit:
func getPage(url string) string {
if GetPageMock != nil {
return GetPageMock()
}
// getPage real implementation goes here!
}
func downloader() {
if GetPageMock != nil {
return GetPageMock()
}
// getPage real implementation goes here!
}
var GetPageMock func(url string) string = nil
var DownloaderMock func() = nil
This way we can actually mock one function out of the others. For more convenient we can provide such mocking boilerplate:
// download.go
func getPage(url string) string {
if m.GetPageMock != nil {
return m.GetPageMock()
}
// getPage real implementation goes here!
}
func downloader() {
if m.GetPageMock != nil {
return m.GetPageMock()
}
// getPage real implementation goes here!
}
type MockHandler struct {
GetPage func(url string) string
Downloader func()
}
var m *MockHandler = new(MockHandler)
func Mock(handler *MockHandler) {
m = handler
}
In test file:
// download_test.go
func GetPageMock(url string) string {
// ...
}
func TestDownloader(t *testing.T) {
Mock(&MockHandler{
GetPage: GetPageMock,
})
// Test implementation goes here!
Mock(new(MockHandler)) // Reset mocked functions
}
Setting the image using picture.ImageLocation()
works fine, but you are using a relative path. Check your path against the location of the .exe
after it is built.
For example, if your .exe
is located at:
<project folder>/bin/Debug/app.exe
The image would have to be at:
<project folder>/bin/Image/1.jpg
Of course, you could just set the image at design-time (the Image
property on the PictureBox
property sheet).
If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image
. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory
to Copy if newer
.
At this point the image file will be copied when you build the application and you can use
picture.ImageLocation = @"Image\1.jpg";

In addition to @Bastet's solution:
Actually we have to kill the process using the address 0.0.0.0:0
. That's why for most of the people killing adb.exe
from Task Manager was working (in my case I was not able to see it even in Task Manager).
Following the @Bastet steps, I found out that some other process was using this address. I went ahead to kill it, and it gave me ACCESS DENIED
as Error
.
So using the tasklist | findstr ****
I found out the name of the process and killed it from Task Manager.
Thereafter it started working.
In my case bas_daemon
and bas_helper
were using this address both of which corresponds to MOBOROBO.
Generally, this should work in Python3:
import urllib.request
..
urllib.request.get(url)
Remember that urllib and urllib2 don't work properly after Python2.
If in some mysterious cases requests don't work (happened with me), you can also try using
wget.download(url)

Here's a decent explanation/solution to find and download all pdf files on a webpage:
IMHO what the best solution is depends to some extent on how you store time in the rest of the database (and the rest of your application)
Personally I have worked with SQLite and try to always use unix timestamps for storing absolute time, so when dealing with the time of day (like you ask for) I do what Glen Solsberry writes in his answer and store the number of seconds since midnight
When taking this general approach people (including me!) reading the code are less confused if I use the same standard everywhere
Just try socket.disconnect(true)
on the server side by emitting any event from the client side.
Actually, it's quite easy: instead of the number of bins you can give a list with the bin boundaries. They can be unequally distributed, too:
plt.hist(data, bins=[0, 10, 20, 30, 40, 50, 100])
If you just want them equally distributed, you can simply use range:
plt.hist(data, bins=range(min(data), max(data) + binwidth, binwidth))
Added to original answer
The above line works for data
filled with integers only. As macrocosme points out, for floats you can use:
import numpy as np
plt.hist(data, bins=np.arange(min(data), max(data) + binwidth, binwidth))
Consider:
class Bike(object):
def __init__(self, name, weight, cost):
self.name = name
self.weight = weight
self.cost = cost
bikes = {
# Bike designed for children"
"Trike": Bike("Trike", 20, 100), # <--
# Bike designed for everyone"
"Kruzer": Bike("Kruzer", 50, 165), # <--
}
# Markup of 20% on all sales
margin = .2
# Revenue minus cost after sale
for bike in bikes.values():
profit = bike.cost * margin
print(profit)
Output:
33.0 20.0
The difference is that in your bikes
dictionary, you're initializing the values as lists [...]
. Instead, it looks like the rest of your code wants Bike
instances. So create Bike
instances: Bike(...)
.
As for your error
AttributeError: 'list' object has no attribute 'cost'
this will occur when you try to call .cost
on a list
object. Pretty straightforward, but we can figure out what happened by looking at where you call .cost
-- in this line:
profit = bike.cost * margin
This indicates that at least one bike
(that is, a member of bikes.values()
is a list). If you look at where you defined bikes
you can see that the values were, in fact, lists. So this error makes sense.
But since your class has a cost attribute, it looked like you were trying to use Bike
instances as values, so I made that little change:
[...] -> Bike(...)
and you're all set.

You have to store the timer id of the interval when you start it, you will use this value later to stop it, using the clearInterval
function:
$(function () {
var timerId = 0;
$('textarea').focus(function () {
timerId = setInterval(function () {
// interval function body
}, 1000);
});
$('textarea').blur(function () {
clearInterval(timerId);
});
});
One other difference lies in the performance.
As the DLL is loaded at runtime by the .exe(s), the .exe(s) and the DLL work with shared memory concept and hence the performance is low relatively to static linking.
On the other hand, a .lib is code that is linked statically at compile time into every process that requests. Hence the .exe(s) will have single memory, thus increasing the performance of the process.
You were right to look at using a set, we just need to dig in a little deeper to get your method to work.
First, the example code:
test_1 = {"foo": "bar", "FOO": "BAR"}
test_2 = {"foo": "bar", "f00": "b@r"}
We can see right now that both dictionaries contain a similar key/value pair:
{"foo": "bar", ...}
Each dictionary also contains a completely different key value pair. But how do we detect the difference? Dictionaries don't support that. Instead, you'll want to use a set.
Here is how to turn each dictionary into a set we can use:
set_1 = set(test_1.items())
set_2 = set(test_2.items())
This returns a set containing a series of tuples. Each tuple represents one key/value pair from your dictionary.
Now, to find the difference between set_1 and set_2:
print set_1 - set_2
>>> {('FOO', 'BAR')}
Want a dictionary back? Easy, just:
dict(set_1 - set_2)
>>> {'FOO': 'BAR'}
More cleaner way using LINQ
var lines = dictionary.Select(kvp => kvp.Key + ": " + kvp.Value.ToString());
textBox3.Text = string.Join(Environment.NewLine, lines);
This functionality is part of the C++11 standard.

returns the number of threads that the hardware is capable of executing concurrently based on the number of CPU cores and hyper-threading units.

Time traveller here
List_of_list =[([z for z in range(x-2,x+1) if z >= 0],y) for y in range(10) for x in range(10)]
This should do the trick. And the output is this:
[([0], 0), ([0, 1], 0), ([0, 1, 2], 0), ([1, 2, 3], 0), ([2, 3, 4], 0), ([3, 4, 5], 0), ([4, 5, 6], 0), ([5, 6, 7], 0), ([6, 7, 8], 0), ([7, 8, 9], 0), ([0], 1), ([0, 1], 1), ([0, 1, 2], 1), ([1, 2, 3], 1), ([2, 3, 4], 1), ([3, 4, 5], 1), ([4, 5, 6], 1), ([5, 6, 7], 1), ([6, 7, 8], 1), ([7, 8, 9], 1), ([0], 2), ([0, 1], 2), ([0, 1, 2], 2), ([1, 2, 3], 2), ([2, 3, 4], 2), ([3, 4, 5], 2), ([4, 5, 6], 2), ([5, 6, 7], 2), ([6, 7, 8], 2), ([7, 8, 9], 2), ([0], 3), ([0, 1], 3), ([0, 1, 2], 3), ([1, 2, 3], 3), ([2, 3, 4], 3), ([3, 4, 5], 3), ([4, 5, 6], 3), ([5, 6, 7], 3), ([6, 7, 8], 3), ([7, 8, 9], 3), ([0], 4), ([0, 1], 4), ([0, 1, 2], 4), ([1, 2, 3], 4), ([2, 3, 4], 4), ([3, 4, 5], 4), ([4, 5, 6], 4), ([5, 6, 7], 4), ([6, 7, 8], 4), ([7, 8, 9], 4), ([0], 5), ([0, 1], 5), ([0, 1, 2], 5), ([1, 2, 3], 5), ([2, 3, 4], 5), ([3, 4, 5], 5), ([4, 5, 6], 5), ([5, 6, 7], 5), ([6, 7, 8], 5), ([7, 8, 9], 5), ([0], 6), ([0, 1], 6), ([0, 1, 2], 6), ([1, 2, 3], 6), ([2, 3, 4], 6), ([3, 4, 5], 6), ([4, 5, 6], 6), ([5, 6, 7], 6), ([6, 7, 8], 6), ([7, 8, 9], 6), ([0], 7), ([0, 1], 7), ([0, 1, 2], 7), ([1, 2, 3], 7), ([2, 3, 4], 7), ([3, 4, 5], 7), ([4, 5, 6], 7), ([5, 6, 7], 7), ([6, 7, 8], 7), ([7, 8, 9], 7), ([0], 8), ([0, 1], 8), ([0, 1, 2], 8), ([1, 2, 3], 8), ([2, 3, 4], 8), ([3, 4, 5], 8), ([4, 5, 6], 8), ([5, 6, 7], 8), ([6, 7, 8], 8), ([7, 8, 9], 8), ([0], 9), ([0, 1], 9), ([0, 1, 2], 9), ([1, 2, 3], 9), ([2, 3, 4], 9), ([3, 4, 5], 9), ([4, 5, 6], 9), ([5, 6, 7], 9), ([6, 7, 8], 9), ([7, 8, 9], 9)]
This is done by list comprehension(which makes looping elements in a list via one line code possible). The logic behind this one-line code is the following:
(1) for x in range(10) and for y in range(10) are employed for two independent loops inside a list
(2) (a list, y) is the general term of the loop, which is why it is placed before two for's in (1)
(3) the length of the list in (2) cannot exceed 3, and the list depends on x, so
[z for z in range(x-2,x+1)]
is used
(4) because z starts from zero but range(x-2,x+1) starts from -2 which isn't what we want, so a conditional statement if z >= 0 is placed at the end of the list in (2)
[z for z in range(x-2,x+1) if z >= 0]
As an addendum to b01's answer, the second argument of $.proxy
is often used to preserve the this
reference. Additional arguments passed to $.proxy
are partially applied to the function, pre-filling it with data. Note that any arguments $.post
passes to the callback will be applied at the end, so doSomething
should have those at the end of its argument list:
function clicked() {
var myDiv = $("#my-div");
var callback = $.proxy(doSomething, this, myDiv);
$.post("someurl.php",someData,callback,"json");
}
function doSomething(curDiv, curData) {
//"this" still refers to the same "this" as clicked()
var serverResponse = curData;
}
This approach also allows multiple arguments to be bound to the callback:
function clicked() {
var myDiv = $("#my-div");
var mySpan = $("#my-span");
var isActive = true;
var callback = $.proxy(doSomething, this, myDiv, mySpan, isActive);
$.post("someurl.php",someData,callback,"json");
}
function doSomething(curDiv, curSpan, curIsActive, curData) {
//"this" still refers to the same "this" as clicked()
var serverResponse = curData;
}
RadPHP (previously known as Delphi for PHP) is the best.
As Abel said, ES Modules in Node >= 14 no longer have require
by default.
If you want to add it, put this code at the top of your file:
import { createRequire } from 'module';
const require = createRequire(import.meta.url);

Most of the time you would create a list in groovy rather than an array. You could do it like this:
names = ["lucas", "Fred", "Mary"]
Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:
names = "lucas Fred Mary".split()
Why are you grouping by? Do you mean order by?
SELECT player_name, player_salary, player_salary * 1.1 AS NewSalary
FROM players
ORDER BY player_salary, player_name;
In my opinion the main form should be responsible for opening both child form. Here is some pseudo that explains what I would do:
// MainForm
private ChildForm childForm;
private MoreForm moreForm;
ButtonThatOpenTheFirstChildForm_Click()
{
childForm = CreateTheChildForm();
childForm.MoreClick += More_Click;
childForm.Show();
}
More_Click()
{
childForm.Close();
moreForm = new MoreForm();
moreForm.Show();
}
You will just need to create a simple event MoreClick in the first child. The main benefit of this approach is that you can replicate it as needed and you can very easily model some sort of basic workflow.

Another option is to do another "git stash" of the local uncommitted changes, then combine the two git stashes. Unfortunately git seems to not have a way to easily combine two stashes.

You can use getElementsByName("input") to get a collection of all the inputs on the page. Then loop through the collection, checking the name on the way. Something like this:

<title>JS Bin</title>
</head>
<body>
<input name="q1_a" type="text" value="1A"/>
<input name="q1_b" type="text" value="1B"/>
<input name="q1_c" type="text" value="1C"/>
<input name="q2_d" type="text" value="2D"/>
<script type="text/javascript">
var inputs = document.getElementsByTagName("input");
for (x = 0 ; x < inputs.length ; x++){
myname = inputs[x].getAttribute("name");
if(myname.indexOf("q1_")==0){
alert(myname);
// do more stuff here
}
}
</script>

Use the SimpleDateFormat
class parse()
method. This method will return a Date
object. You can then create a Calendar
object for this Date
and add 2 hours to it.
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = formatter.parse(theDateToParse);
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.HOUR_OF_DAY, 2);
cal.getTime(); // This will give you the time you want.

It's strange because @ControllerAdvice should works, are you catching the correct Exception?

@ResponseBody
@ExceptionHandler(value = DataAccessException.class)
public String defaultErrorHandler(HttpServletResponse response, DataAccessException e) throws Exception {
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
//Json return
}
}
Also try to catch this exception in CorsFilter and send 500 error, something like this
@ExceptionHandler(DataAccessException.class)
@ResponseBody
public String handleDataException(DataAccessException ex, HttpServletResponse response) {
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
//Json return
}
There are three options, that you can use. -I
is to exclude binary files in grep. Other are for line numbers and file names.
grep -I -n -H
-I -- process a binary file as if it did not contain matching data;
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match
So this might be a way to run grep:
grep -InH your-word *
Your '/0'
should be '\0'
.. you got the slash reversed/leaning the wrong way. Your while
should look like:
while (*(forward++)!='\0')
though the != '\0'
part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).
All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t'
, or newline '\n'
, and the same for null '\0'
so it's easy to remember.
Also: Psyco vs. C++.
It's still a bad comparison, since noone would do the numbercrunchy stuff benchmarks tend to focus on in pure Python anyway. A better one would be comparing the performance of realistic applications, or C++ versus NumPy, to get an idea whether your program will be noticeably slower.

else {
System.out.println(moleGrid[i][j]);

Could you have multiple local databases? Check your database.yml
and make sure you are hitting the pg db that you want. Use rails console
to confirm.
The columns
parameter accepts a collection of column names. You're passing a list containing a dataframe with two rows:
>>> [df[1:]]
[ viz a1_count a1_mean a1_std
1 n 0 NaN NaN
2 n 2 51 50]
>>> df.as_matrix(columns=[df[1:]])
array([[ nan, nan],
[ nan, nan],
[ nan, nan]])
Instead, pass the column names you want:
>>> df.columns[1:]
Index(['a1_count', 'a1_mean', 'a1_std'], dtype='object')
>>> df.as_matrix(columns=df.columns[1:])
array([[ 3. , 2. , 0.816497],
[ 0. , nan, nan],
[ 2. , 51. , 50. ]])

I know this is an old thread but for anyone looking to retrieve a script after ssms crashes do the following
You could always create an intermediate class/interface that would satisfy the generic type that you are wanting to specify. For example, if Foo was an interface, you could create the following interface in your test class.
private interface FooBar extends Foo<Bar>
{
}
In situations where Foo is a non-final class, you could just extend the class with the following code and do the same thing:
public class FooBar extends Foo<Bar>
{
}
Then you could consume either of the above examples with the following code:
Foo<Bar> mockFoo = mock(FooBar.class);
when(mockFoo.getValue()).thenReturn(new Bar());
Encapsulation: binding the data members and member functions together is called encapsulation. encapsulation is done through class. abstraction: hiding the implementation details form usage or from view is called abstraction. ex: int x; we don't know how int will internally work. but we know int will work. that is abstraction.
You can use ES6 backtick syntax too
<a href={`/customer/${item._id}`} >{item.get('firstName')} {item.get('lastName')}</a>
I was also facing this issue but in a little different scenario.

It looks simple and a stupid mistake here, but due to multiple lines of codes in the actual code, it took some time for me to figure out that the variable name I was using was same as my function name because of which I was getting this error.
Changed function name to something else and it worked.
So, basically, according to what I understood, this error means that you are trying to use an integer as a function or in more simple terms, the called function name is also used as an integer somewhere in the code. So, just try to find out all occurrences of the called function name and look if that is being used as an integer somewhere.
I struggled to find this, so, sharing it here so that someone else may save their time, in case if they get into this issue.
Hope this helps!
Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.
In fragments we need a view of that window so that we make a onCreateView of this Fragment.
Then get the view and use it to access each and every view id of that view elements..
class Demo extends Fragment
{
@Override
public View onCreateView(final LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState)
{
View view =inflater.inflate(R.layout.demo_fragment, container,false);
ImageView imageview=(ImageView)view.findViewById(R.id.imageview1);
return view;
}
}
By default, on many platforms the short will be aligned to an offset at a multiple of 2, so there will be a padding byte added after the char.
To disable this, use: struct.unpack("=BH", data)
. This will use standard alignment, which doesn't add padding:
>>> struct.calcsize('=BH')

The =
character will use native byte ordering. You can also use <
or >
instead of =
to force little-endian or big-endian byte ordering, respectively.
char a[2]
defines an array of char
's. a
is a pointer to the memory at the beginning of the array and using ==
won't actually compare the contents of a
with 'ab'
because they aren't actually the same types, 'ab'
is integer type. Also 'ab'
should be "ab"
otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.
Something that might be illustrative is looking at the typeid
of 'ab'
:
#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
int some_int =5;
std::cout << typeid('ab').name() << std::endl;
std::cout << typeid(some_int).name() << std::endl;
return 0;
}
on my system this returns:
i
i
showing that 'ab'
is actually evaluated as an int.
If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator ==
overloaded and will do a comparison check when called this way.
If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:
#include <iostream>
#include <string>
using namespace std;
int main(){
string a;
cout<<"enter ab ";
cin>>a;
if(a=="ab"){
cout<<"correct";
}
return 0;
}
This one is due to:
if(a=='ab')
, here, a
is const char*
type (ie : array of char)
'ab'
is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.
Since char
is a primitive type inherited from C, no operator ==
is defined.
the good code should be:
if(strcmp(a,"ab")==0)
, then you'll compare a const char*
to another const char*
using strcmp
.
Try this
ALTER TABLE `users` ADD `id` INT NOT NULL AUTO_INCREMENT;
for an existing primary key
Just to provide some variation here: You could check for
if ($_SERVER["QUERY_STRING"] == null)
it is completely identical to testing $_GET
.
As mentioned in an above answer, the Scala List is an immutable collection. You can create an empty list with .empty[A]
. Then you can use a method :+
, +:
or ::
in order to add element to the list.
scala> val strList = List.empty[String]
strList: List[String] = List()
scala> strList:+ "Text"
res3: List[String] = List(Text)
scala> val mapList = List.empty[Map[String, Any]]
mapList: List[Map[String,Any]] = List()
scala> mapList :+ Map("1" -> "ok")
res4: List[Map[String,Any]] = List(Map(1 -> ok))
In some cases, you need to force refresh the view in order to make it work.
toggleButton.setTextOff(textOff);
toggleButton.requestLayout();
toggleButton.setTextOn(textOn);
toggleButton.requestLayout();
For those running in such issues right now, just try to put an alias for the table, this should the trick, e.g:
SELECT myvalue
INTO myvar
FROM mytable x
WHERE x.anothervalue = 1;
It worked for me.
Cheers.
My first response was made before iOS 7 introduced explicit support for displaying attributed strings in common controls. You may now set attributedText
of UITextView
to an NSAttributedString
created from HTML content using:
-(id)initWithData:(NSData *)data options:(NSDictionary *)options documentAttributes:(NSDictionary **)dict error:(NSError **)error
- initWithData:options:documentAttributes:error: (Apple Doc)
Original answer, preserved for history:
Unless you use a UIWebView
, your solution will rely directly on CoreText
. As ElanthiraiyanS points out, some open source projects have emerged to simplify rich text rendering. I would recommend NSAttributedString-Additions-For-HTML (Edit: the project has been supplanted DTCoreText), which features classes to generate and display attributed strings from HTML.

getPathInfo() sometimes return null. In documentation HttpServletRequest
This method returns null if there was no extra path information.
I need get path to file without context path in Filter and getPathInfo() return me null. So I use another method: httpRequest.getServletPath()
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
String newPath = parsePathToFile(httpRequest.getServletPath());
...
}

WAMP: acronym for Windows Operating System, Apache(Web server), MySQL Database and PHP Language.
XAMPP: acronym for X (any Operating System), Apache (Web server), MySQL Database, PHP Language and PERL.
XAMPP and WampServer are both free packages of WAMP, with additional applications/tools, put together by different people.
Their differences are in the format/structure of the package, the configurations, and the included management applications.
In short: XAMPP supports more OSes and includes more features
You could use the ngSwitch directive:
<div ng-switch on="selection" >
<div ng-switch-when="settings">Settings Div</div>
<span ng-switch-when="home">Home Span</span>
<span ng-switch-default>default</span>
</div>
If you don't want the DOM to be loaded with empty divs, you need to create your custom directive using $http to load the (sub)templates and $compile to inject it in the DOM when a certain condition has reached.
This is just an (untested) example. It can and should be optimized:
HTML:
<conditional-template ng-model="element" template-url1="path/to/partial1" template-url2="path/to/partial2"></div>
Directive:
app.directive('conditionalTemplate', function($http, $compile) {
return {
restrict: 'E',
require: '^ngModel',
link: function(sope, element, attrs, ctrl) {
// get template with $http
// check model via ctrl.$viewValue
// compile with $compile
// replace element with element.replaceWith()
}
};
});

What works for me is to make sure I do the standard JQuery library loading via a < script > tag in the index.html.
Run
npm install --save @types/jquery
Now the JQuery $ functions are available in all .ts files, no need of any other imports.
I ran into a similar problem with the same error message using following code:
@Html.DisplayFor(model => model.EndDate.Value.ToShortDateString())
I found a good answer here
Turns out you can decorate the property in your model with a displayformat then apply a dataformatstring.
Be sure to import the following lib into your model:
using System.ComponentModel.DataAnnotations;
breast$class <- as.numeric(as.character(breast$class))
If you have many columns to convert to numeric
indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))
Another option is to use stringsAsFactors=FALSE
while reading the file using read.table
or read.csv
Just in case, other options to create/change columns
breast[,'class'] <- as.numeric(as.character(breast[,'class']))
or
breast <- transform(breast, class=as.numeric(as.character(breast)))

Until Android 7.1 you will get it with:
Build.SERIAL
On Android 8 (SDK 26) and above, this field will return UNKNOWN
and must be accessed with:
Build.getSerial()
which requires the dangerous permission
android.permission.READ_PHONE_STATE
.
Since Android Q using Build.getSerial()
gets a bit more complicated by requiring:
android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE
(which can only be acquired by system apps), or for the calling package to be the device or profile owner and have the READ_PHONE_STATE
permission. This means most apps won't be able to uses this feature. See the Android Q announcement from Google.
If you just require a unique identifier, it's best to avoid using hardware identifiers as Google continuously tries to make it harder to access them for privacy reasons. You could just generate a UUID.randomUUID().toString();
and save it the first time it needs to be accessed in e.g. shared preferences. Alternatively you could use ANDROID_ID
which is a 8 byte long hex string unique to the device, user and (only Android 8+) app installation. For more info on that topic, see Best practices for unique identifiers.
Here is the CLRS Implementation:
def merge(arr, p, q, r):
n1 = q - p + 1
n2 = r - q
right, left = [], []
for i in range(n1):
left.append(arr[p + i])
for j in range(n2):
right.append(arr[q + j + 1])
left.append(float('inf'))
right.append(float('inf'))
i = j = 0
for k in range(p, r + 1):
if left[i] <= right[j]:
arr[k] = left[i]
i += 1
else:
arr[k] = right[j]
j += 1
def merge_sort(arr, p, r):
if p < r:
q = (p + r) // 2
merge_sort(arr, p, q)
merge_sort(arr, q + 1, r)
merge(arr, p, q, r)
if __name__ == '__main__':
test = [5, 2, 4, 7, 1, 3, 2, 6]
merge_sort(test, 0, len(test) - 1)
print test
Result:
[1, 2, 2, 3, 4, 5, 6, 7]
It sounds like installing the VS2017 update for that specific version didn't also install the .NET Core 2.0 SDK. You can download that here.
To check which version of the SDK you've already got installed, run
dotnet --info
from the command line. Note that if there's a global.json
file in either your current working directory or any ancestor directory, that will override which version of the SDK is run. (That's useful if you want to enforce a particular version for a project, for example.)
Judging by comments, some versions of VS2017 updates do install the .NET Core SDK. I suspect it may vary somewhat over time.

Expanding on @dogbane's answer, you can get all the PIDs for a named process with pgrep

I agree with the event emitting and v-model answers for those above. However, I thought I would post what I found about components with multiple form elements that want to emit back to their parent since this seems one of the first articles returned by google.
I know the question specifies a single input, but this seemed the closest match and might save people some time with similar vue components. Also, no one has mentioned the .sync
modifier yet.
As far as I know, the v-model
solution is only suited to one input returning to their parent. I took a bit of time looking for it but Vue (2.3.0) documentation does show how to sync multiple props sent into the component back to the parent (via emit of course).
It is appropriately called the .sync
modifier.
Here is what the documentation says:
In some cases, we may need “two-way binding” for a prop. Unfortunately, true two-way binding can create maintenance issues, because child components can mutate the parent without the source of that mutation being obvious in both the parent and the child.
That’s why instead, we recommend emitting events in the pattern of
update:myPropName
. For example, in a hypothetical component with atitle
prop, we could communicate the intent of assigning a new value with:
this.$emit('update:title', newTitle)
Then the parent can listen to that event and update a local data property, if it wants to. For example:
<text-document
v-bind:title="doc.title"
v-on:update:title="doc.title = $event"
></text-document>
For convenience, we offer a shorthand for this pattern with the .sync modifier:
<text-document v-bind:title.sync="doc.title"></text-document>
You can also sync multiple at a time by sending through an object. Check out the documentation here
loads of reading documentation on how to round numbers, many experts suggest writing your own rounding routines, as the 'canned' version provided with your language may not be precise enough, or contain errors. i imagine, however, they're talking many decimal places not just one, two, or three. with that in mind, here is my solution (although not EXACTLY as requested as my needs are to display dollars - the process is not much different, though).
sub asDollars($) {
my ($cost) = @_;
my $rv = 0;
my $negative = 0;
if ($cost =~ /^-/) {
$negative = 1;
$cost =~ s/^-//;
}
my @cost = split(/\./, $cost);
# let's get the first 3 digits of $cost[1]
my ($digit1, $digit2, $digit3) = split("", $cost[1]);
# now, is $digit3 >= 5?
# if yes, plus one to $digit2.
# is $digit2 > 9 now?
# if yes, $digit2 = 0, $digit1++
# is $digit1 > 9 now??
# if yes, $digit1 = 0, $cost[0]++
if ($digit3 >= 5) {
$digit3 = 0;
$digit2++;
if ($digit2 > 9) {
$digit2 = 0;
$digit1++;
if ($digit1 > 9) {
$digit1 = 0;
$cost[0]++;
}
}
}
$cost[1] = $digit1 . $digit2;
if ($digit1 ne "0" and $cost[1] < 10) { $cost[1] .= "0"; }
# and pretty up the left of decimal
if ($cost[0] > 999) { $cost[0] = commafied($cost[0]); }
$rv = join(".", @cost);
if ($negative) { $rv = "-" . $rv; }
return $rv;
}
sub commafied($) {
#*
# to insert commas before every 3rd number (from the right)
# positive or negative numbers
#*
my ($num) = @_; # the number to insert commas into!
my $negative = 0;
if ($num =~ /^-/) {
$negative = 1;
$num =~ s/^-//;
}
$num =~ s/^(0)*//; # strip LEADING zeros from given number!
$num =~ s/0/-/g; # convert zeros to dashes because ... computers!
if ($num) {
my @digits = reverse split("", $num);
$num = "";
for (my $i = 0; $i < @digits; $i += 3) {
$num .= $digits[$i];
if ($digits[$i+1]) { $num .= $digits[$i+1]; }
if ($digits[$i+2]) { $num .= $digits[$i+2]; }
if ($i < (@digits - 3)) { $num .= ","; }
if ($i >= @digits) { last; }
}
#$num =~ s/,$//;
$num = join("", reverse split("", $num));
$num =~ s/-/0/g;
}
if ($negative) { $num = "-" . $num; }
return $num; # a number with commas added
#usage: my $prettyNum = commafied(1234567890);
}
I had the same problem with posting a form. What I did was that turning off the data-ajax.
In general, you can use the built-in credential storage facilities:
git config --global credential.helper store
Or, if you're on Windows, you can use their credential system:
git config --global credential.helper wincred
Or, if you're on MacOS, you can use their credential system:
git config --global credential.helper osxkeychain
The first solution is optimal in most situations.
Use your bean class like this, if your JSON data starts with an an array object. it helps you.
Users[] bean = gson.fromJson(response,Users[].class);
Users is my bean class.
Response is my JSON data.
Use KeyPressEventArgs,
Private Sub ComboBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBox1.KeyPress
e.Handled = True
End Sub
ConcurrentLinkedQueue is lock-free, LinkedBlockingQueue is not. Every time you invoke LinkedBlockingQueue.put() or LinkedBlockingQueue.take(), you need acquire the lock first. In other word, LinkedBlockingQueue has poor concurrency. If you care performance, try ConcurrentLinkedQueue + LockSupport.

When using guava (See doc) there is Iterators.forEnumeration
. Given an Enumeration x
you can do the following:
to get a immutable Set:
ImmutableSet.copyOf(Iterators.forEnumeration(x));
to get a immutable List:
ImmutableList.copyOf(Iterators.forEnumeration(x));
to get a hashSet:
Sets.newHashSet(Iterators.forEnumeration(x));
