Yes, ConfigurationManager.AppSettings
is available in .NET Core 2.0 after referencing NuGet package System.Configuration.ConfigurationManager
.
Credits goes to @JeroenMostert for giving me the solution.
You can use Microsoft.Extensions.Configuration API with any .NET Core app, not only with ASP.NET Core app. Look into sample provided in the link, that shows how to read configs in the console app.
In most cases, the JSON source (read as .json
file) is the most suitable config source.
Note: don't be confused when someone says that config file should be
appsettings.json
. You can use any file name, that is suitable for you and file location may be different - there are no specific rules.
But, as the real world is complicated, there are a lot of different configuration providers:
and so on. You even could use/write a custom provider.
Actually, app.config
configuration file was an XML file. So you can read settings from it using XML configuration provider (source on github, nuget link). But keep in mind, it will be used only as a configuration source - any logic how your app behaves should be implemented by you. Configuration Provider will not change 'settings' and set policies for your apps, but only read data from the file.
Cleaning solution worked for me.
I would also advise to close and relaunch Visual Studio once doing so.
For ASP.NET Core 3.1 you can follow this documentation:
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1
When you create a new ASP.NET Core 3.1 project you will have the following configuration line in Program.cs
:
Host.CreateDefaultBuilder(args)
This enables the following:
This means you can inject IConfiguration
and fetch values with a string key, even nested values. Like IConfiguration ["Parent:Child"];
Example:
appsettings.json
{
"ApplicationInsights":
{
"Instrumentationkey":"putrealikeyhere"
}
}
WeatherForecast.cs
[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
private static readonly string[] Summaries = new[]
{
"Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
};
private readonly ILogger<WeatherForecastController> _logger;
private readonly IConfiguration _configuration;
public WeatherForecastController(ILogger<WeatherForecastController> logger, IConfiguration configuration)
{
_logger = logger;
_configuration = configuration;
}
[HttpGet]
public IEnumerable<WeatherForecast> Get()
{
var key = _configuration["ApplicationInsights:InstrumentationKey"];
var rng = new Random();
return Enumerable.Range(1, 5).Select(index => new WeatherForecast
{
Date = DateTime.Now.AddDays(index),
TemperatureC = rng.Next(-20, 55),
Summary = Summaries[rng.Next(Summaries.Length)]
})
.ToArray();
}
}
I had this when build my application with "All cpu" target while it referenced a 3rd party x64-only (managed) dll.
Try below piece of code.
this.dataGridView1.RefreshEdit();
Okay, it took me a while to see this, but there's no way this compiles:
return String.(ConfigurationManager.AppSettings[paramName]);
You're not even calling a method on the String
type. Just do this:
return ConfigurationManager.AppSettings[paramName];
The AppSettings
KeyValuePair already returns a string. If the name doesn't exist, it will return null
.
Based on your edit you have not yet added a Reference to the System.Configuration
assembly for the project you're working in.
You can enable NuGet packages and update you dlls. so that it work. or you can update the package manually by going through the package manager in your vs if u know which version you require for your solution.
This problem would be caused by your application missing a reference to an external dll that you are trying to use code from. Usually Visual Studio should give you an idea about which objects that it doesn't know what to do with so that should be a step in the right direction.
You need to look in the solution explorer and right click on project references and then go to add -> and look up the one you need. It's most likely the System.Configuration assembly as most people have pointed out here while should be under the Framework option in the references window. That should resolve your issue.
In static class, if you are getting information from xml or reg, class tries to initialize all properties. therefore, you should control if the config variable is there otherwise properties will not initialize so the class.
Check xml referance variable is there, Check reg referance variable is is there, Make sure you handle if they are not there.
I too had the same error in trace logs. My newly created function in API was throwing the same error but to my surprise, the old functions were performing good. The issue was - My contract data members had few variables of type object. soap-xml was not able to handle it well, however, I can see that array of object types (object[]) were getting passed without any issues. Only a simple object type was not getting parsed by soap. This could be one more reason why the services throw the above error.
Please, never use this concat form:
String st = "UPDATE supplier SET supplier_id = " + textBox1.Text + ", supplier_name = " + textBox2.Text
+ "WHERE supplier_id = " + textBox1.Text;
use:
command.Parameters.AddWithValue("@attribute", value);
Always work object oriented
Edit: This is because when you parameterize your updates it helps prevent SQL injection.
Wrap your all statements in !IsPostBack
condition on page load.
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
// all statements
}
}
This will fix your issue.
The SqlDataReader
is a valid data source for the DataTable
. As such, all you need to do its this:
public DataTable GetData()
{
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["BarManConnectionString"].ConnectionString);
conn.Open();
string query = "SELECT * FROM [EventOne]";
SqlCommand cmd = new SqlCommand(query, conn);
DataTable dt = new DataTable();
dt.Load(cmd.ExecuteReader());
conn.Close();
return dt;
}
AppSettings.Set
does not persist the changes to your configuration file. It just changes it in memory. If you put a breakpoint on System.Configuration.ConfigurationManager.AppSettings.Set("lang", lang);
, and add a watch for System.Configuration.ConfigurationManager.AppSettings[0]
you will see it change from "English" to "Russian" when that line of code runs.
The following code (used in a console application) will persist the change.
class Program
{
static void Main(string[] args)
{
UpdateSetting("lang", "Russian");
}
private static void UpdateSetting(string key, string value)
{
Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
configuration.AppSettings.Settings[key].Value = value;
configuration.Save();
ConfigurationManager.RefreshSection("appSettings");
}
}
From this post: http://vbcity.com/forums/t/152772.aspx
One major point to note with the above is that if you are running this from the debugger (within Visual Studio) then the app.config file will be overwritten each time you build. The best way to test this is to build your application and then navigate to the output directory and launch your executable from there. Within the output directory you will also find a file named YourApplicationName.exe.config which is your configuration file. Open this in Notepad to see that the changes have in fact been saved.
A couple of things wrong here.
Do you really want to open and close the connection for every single log entry?
Shouldn't you be using SqlCommand
instead of SqlDataAdapter
?
The data adapter (or SqlCommand
) needs exactly what the error message tells you it's missing: an active connection. Just because you created a connection object does not magically tell C# that it is the one you want to use (especially if you haven't opened the connection).
I highly recommend a C# / SQL Server tutorial.
The first step is to create the helper class for the HTTP client.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
namespace callApi.Helpers
{
public class CallApi
{
private readonly Uri BaseUrlUri;
private HttpClient client = new HttpClient();
public CallApi(string baseUrl)
{
BaseUrlUri = new Uri(baseUrl);
client.BaseAddress = BaseUrlUri;
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
}
public HttpClient getClient()
{
return client;
}
public HttpClient getClientWithBearer(string token)
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
return client;
}
}
}
Then you can use this class in your code.
This is an example of how you call the REST API without bearer using the above class.
// GET API/values
[HttpGet]
public async Task<ActionResult<string>> postNoBearerAsync(string email, string password,string baseUrl, string action)
{
var request = new LoginRequest
{
email = email,
password = password
};
var callApi = new CallApi(baseUrl);
var client = callApi.getClient();
HttpResponseMessage response = await client.PostAsJsonAsync(action, request);
if (response.IsSuccessStatusCode)
return Ok(await response.Content.ReadAsAsync<string>());
else
return NotFound();
}
This is an example of how you can call the REST API that require bearer.
// GET API/values
[HttpGet]
public async Task<ActionResult<string>> getUseBearerAsync(string token, string baseUrl, string action)
{
var callApi = new CallApi(baseUrl);
var client = callApi.getClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
HttpResponseMessage response = await client.GetAsync(action);
if (response.IsSuccessStatusCode)
{
return Ok(await response.Content.ReadAsStringAsync());
}
else
return NotFound();
}
You can also refer to the below repository if you want to see the working example of how it works.
An XSD is included with EntLib 5, and is installed in the Visual Studio schema directory. In my case, it could be found at:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas\EnterpriseLibrary.Configuration.xsd
It is worth repeating that these "Error List" "Messages" ("Could not find schema information for the element") are only visible when you open the app.config file. If you "Close All Documents" and compile... no messages will be reported.
There will be two Web.config files. I think you may have confused with those two files.
Check this image:
In this image you can see two Web.config files. You should add your constants to the one which is in the project folder not in the views folder
Hope this may help you
I got this exception while coping a object(variable) Matrix Array into Excel sheet. The solution to this is, Matrix array Index(i,j) must start from (0,0) whereas Excel sheet should start with Matrix Array index (i,j) from (1,1) .
I hope you this concept.
You can do this by reading from the boolean property at:
System.Web.Security.Roles.Enabled
This is a direct read from the enabled
attribute of the roleManager
element in the web.config
:
<configuration>
<system.web>
<roleManager enabled="true" />
</system.web>
</configuration>
Update:
For more information, check out this MSDN sample: https://msdn.microsoft.com/en-us/library/aa354509(v=vs.110).aspx
The only way I can get this to work is to manually instantiate the section handler type, pass the raw XML to it, and cast the resulting object.
Seems pretty inefficient, but there you go.
I wrote an extension method to encapsulate this:
public static class ConfigurationSectionExtensions
{
public static T GetAs<T>(this ConfigurationSection section)
{
var sectionInformation = section.SectionInformation;
var sectionHandlerType = Type.GetType(sectionInformation.Type);
if (sectionHandlerType == null)
{
throw new InvalidOperationException(string.Format("Unable to find section handler type '{0}'.", sectionInformation.Type));
}
IConfigurationSectionHandler sectionHandler;
try
{
sectionHandler = (IConfigurationSectionHandler)Activator.CreateInstance(sectionHandlerType);
}
catch (InvalidCastException ex)
{
throw new InvalidOperationException(string.Format("Section handler type '{0}' does not implement IConfigurationSectionHandler.", sectionInformation.Type), ex);
}
var rawXml = sectionInformation.GetRawXml();
if (rawXml == null)
{
return default(T);
}
var xmlDocument = new XmlDocument();
xmlDocument.LoadXml(rawXml);
return (T)sectionHandler.Create(null, null, xmlDocument.DocumentElement);
}
}
The way you would call it in your example is:
var map = new ExeConfigurationFileMap
{
ExeConfigFilename = @"c:\\foo.config"
};
var configuration = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
var myParamsSection = configuration.GetSection("MyParams");
var myParamsCollection = myParamsSection.GetAs<NameValueCollection>();
Try to rebuild your project - It copies the content of App.config
to
"<YourProjectName.exe>.config" in the build library.
I had this issue, as I had copied a (fairly generic) webpage from one of my ASP.Net applications into a new application.
I changed the relevant namespace commands, to reflect the new location of the file... but... I had forgotten to change the Inherits parameter in the aspx page itself.
<%@ Page MasterPageFile="" StylesheetTheme="" Language="C#"
AutoEventWireup="true" CodeBehind="MikesReports.aspx.cs"
Inherits="MikesCompany.MikesProject.MikesReports" %>
Once I had changed the Inherits parameter, the error went away.
Thank for the question. But I have found my own solution to this problem. At first, I created a method
public T GetSettingsWithDictionary<T>() where T:new()
{
IConfigurationRoot _configurationRoot = new ConfigurationBuilder()
.AddXmlFile($"{Assembly.GetExecutingAssembly().Location}.config", false, true).Build();
var instance = new T();
foreach (var property in typeof(T).GetProperties())
{
if (property.PropertyType == typeof(Dictionary<string, string>))
{
property.SetValue(instance, _configurationRoot.GetSection(typeof(T).Name).Get<Dictionary<string, string>>());
break;
}
}
return instance;
}
Then I used this method to produce an instance of a class
var connStrs = GetSettingsWithDictionary<AuthMongoConnectionStrings>();
I have the next declaration of class
public class AuthMongoConnectionStrings
{
public Dictionary<string, string> ConnectionStrings { get; set; }
}
and I store my setting in App.config
<configuration>
<AuthMongoConnectionStrings
First="first"
Second="second"
Third="33" />
</configuration>
In your project, right-click, Add Reference..., in the .NET tab, find the System.Configuration
component name and click OK.
using System.Configuration
tells the compiler/IntelliSense to search in that namespace for any classes you use. Otherwise, you would have to use the full name (System.Configuration.ConfigurationManager
) every time. But if you don't add the reference, that namespace/class will not be found anywhere.
Note that a DLL can have any namespace, so the file System.Configuration.dll
could, in theory, have the namespace Some.Random.Name
. For clarity/consistency they're usually the same, but there are exceptions.
Your data class doesn't match the JSON object. Use this instead:
[DataContract]
public class GoogleSearchResults
{
[DataMember]
public ResponseData responseData { get; set; }
}
[DataContract]
public class ResponseData
{
[DataMember]
public IEnumerable<Results> results { get; set; }
}
[DataContract]
public class Results
{
[DataMember]
public string unescapedUrl { get; set; }
[DataMember]
public string url { get; set; }
[DataMember]
public string visibleUrl { get; set; }
[DataMember]
public string cacheUrl { get; set; }
[DataMember]
public string title { get; set; }
[DataMember]
public string titleNoFormatting { get; set; }
[DataMember]
public string content { get; set; }
}
Also, you don't have to instantiate the class to get its type for deserialization:
public static T Deserialise<T>(string json)
{
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
var serialiser = new DataContractJsonSerializer(typeof(T));
return (T)serialiser.ReadObject(ms);
}
}
I always create an IConfig interface with typesafe properties declared for all configuration values. A Config implementation class then wraps the calls to System.Configuration. All your System.Configuration calls are now in one place, and it is so much easier and cleaner to maintain and track which fields are being used and declare their default values. I write a set of private helper methods to read and parse common data types.
Using an IoC framework you can access the IConfig fields anywhere your in application by simply passing the interface to a class constructor. You're also then able to create mock implementations of the IConfig interface in your unit tests so you can now test various configuration values and value combinations without needing to touch your App.config or Web.config file.
To Get The Data From the App.config
Keeping in mind you have to:
System.Configuration
using System.Configuration;
Just Simply do this
string value1 = ConfigurationManager.AppSettings["Value1"];
Alternatively, you can achieve this in one line, if you don't want to add using System.Configuration;
explicitly.
string value1 = System.Configuration.ConfigurationManager.AppSettings["Value1"]
When you use
cmd.Parameters.Add("@RETURN_VALUE", SqlDbType.Int).Direction = ParameterDirection.ReturnValue;
you must then ensure your stored procedure has
return @RETURN_VALUE;
at the end of the stored procedure.
Clarification of previous answers...
Add a new file to your project (Add → New Item → Application Configuration File)
The new configuration file will appear in Solution Explorer as App.Config.
Add your settings into this file using the following as a template
<configuration>
<appSettings>
<add key="setting1" value="key"/>
</appSettings>
<connectionStrings>
<add name="prod" connectionString="YourConnectionString"/>
</connectionStrings>
</configuration>
Retrieve them like this:
private void Form1_Load(object sender, EventArgs e)
{
string setting = ConfigurationManager.AppSettings["setting1"];
string conn = ConfigurationManager.ConnectionStrings["prod"].ConnectionString;
}
When built, your output folder will contain a file called <assemblyname>.exe.config. This will be a copy of the App.Config file. No further work should need to be done by the developer to create this file.
I am no expert at this (and this page was very helpful along with http://mywiki.wooledge.org/UsingFind)
Just noticed -path
is for a path that fully matches the string/path that comes just after find
(.
in theses examples) where as -name
matches all basenames.
find . -path ./.git -prune -o -name file -print
blocks the .git directory in your current directory ( as your finding in .
)
find . -name .git -prune -o -name file -print
blocks all .git subdirectories recursively.
Note the ./
is extremely important!! -path
must match a path anchored to .
or whatever comes just after find if you get matches with out it (from the other side of the or '-o
') there probably not being pruned!
I was naively unaware of this and it put me of using -path when it is great when you don't want to prune all subdirectory with the same basename :D
You can also try: (I tried this and it worked for me)
SELECT ISNULL((SELECT SUM(columnA) FROM my_table WHERE columnB = 1),0)) INTO res;
I had the same issue - re-adding the migration and updating the database didn't work and none of the answers above seemed right. Then inspiration hit me - I'm using multiple tiers (one web, one data, and one business). The data layer has the context and all the models. The web layer never threw this exception - it was the business layer (which I set as console application for testing and debugging). Turns out the business layer wasn't using the right connection string to get the db and make the context. So I added the connection string to the app config of the business layer (and the data layer) and viola it works. Putting this here for others who may encounter the same issue.
First, let gradle set the correct distribution Url
cd projectDirectory
./gradlew wrapper --gradle-version 2.3.0
Then - might not be needed but that's what I did - edit the project's build.gradle to match the version
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
Finally, delete the folders .gradle and gradle and the files gradlew and gradlew.bat. (Original Answer)
Now, rebuild the project.
As the other answers did not suffice for me and the comment pointing out these additional steps is easy to overlook, here as a separate answer
I needed an iframe that would embed a portion of an external page with a vertical scroll bar, cropping out the navigation menus on the top and left of the page. I was able to do it with some simple HTML and CSS.
HTML
<div id="container">
<iframe id="embed" src="http://www.example.com"></iframe>
</div>
CSS
div#container
{
width:840px;
height:317px;
overflow:scroll; /* if you don't want a scrollbar, set to hidden */
overflow-x:hidden; /* hides horizontal scrollbar on newer browsers */
/* resize and min-height are optional, allows user to resize viewable area */
-webkit-resize:vertical;
-moz-resize:vertical;
resize:vertical;
min-height:317px;
}
iframe#embed
{
width:1000px; /* set this to approximate width of entire page you're embedding */
height:2000px; /* determines where the bottom of the page cuts off */
margin-left:-183px; /* clipping left side of page */
margin-top:-244px; /* clipping top of page */
overflow:hidden;
/* resize seems to inherit in at least Firefox */
-webkit-resize:none;
-moz-resize:none;
resize:none;
}
Unordered lists are often created with the intent of using them as a menu, but an li
list item is text. Because the list li
item is text, the mouse pointer will not be an arrow, but an "I cursor". Users are accustomed to seeing a pointing finger for a mouse pointer when something is clickable. Using an anchor tag a
inside of the li
tag causes the mouse pointer to change to a pointing finger. The pointing finger is a lot better for using the list as a menu.
<ul id="menu">
<li><a href="#">Menu Item 1</a></li>
<li><a href="#">Menu Item 2</a></li>
<li><a href="#">Menu Item 3</a></li>
<li><a href="#">Menu Item 4</a></li>
</ul>
If the list is being used for a menu, and doesn't need a link, then a URL doesn't need to be designated. But the problem is that if you leave out the href
attribute, text in the <a>
tag is seen as text, and therefore the mouse pointer is back to an I-cursor. The I-cursor might make the user think that the menu item is not clickable. Therefore, you still need an href
, but you don't need a link to anywhere.
You could use lots of div
or p
tags for a menu list, but the mouse pointer would be an I-cursor for them also.
You could use lots of buttons stacked on top of each other for a menu list, but the list seems to be preferable. And that's probably why the href="#"
that points to nowhere is used in anchor tags inside of list tags.
You can set the pointer style in CSS, so that is another option. The href="#"
to nowhere might just be the lazy way to set some styling.
alternatively to append()
you can also use appendTo()
which has a different syntax:
$("#foo").append("<div>hello world</div>");
$("<div>hello world</div>").appendTo("#foo");
You can implicitly convert between numerical types, even when that loses precision:
char c = i;
However, you might like to enable compiler warnings to avoid potentially lossy conversions like this. If you do, then use static_cast
for the conversion.
Of the other casts:
dynamic_cast
only works for pointers or references to polymorphic class types;const_cast
can't change types, only const
or volatile
qualifiers;reinterpret_cast
is for special circumstances, converting between pointers or references and completely unrelated types. Specifically, it won't do numeric conversions.static_cast
, const_cast
and reinterpret_cast
is needed to get the job done.#!/usr/bin/env python

It's an old question but here is a concise, readable, JDK-only solution with properly closed resources:
static long download(String sourceUrl, String targetFileName) throws Exception {
try (InputStream in = URI.create(sourceUrl).toURL().openStream()) {
return Files.copy(in, Paths.get(targetFileName));
}
}
Two lines of code and no dependencies.
Here's a complete file downloader example program with output, error checking, and command line argument checks:
package so.downloader;
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URI;
import java.nio.file.Files;
import java.nio.file.Paths;
public class Application {
public static void main(String[] args) throws MalformedURLException, IOException {
if (2 != args.length) {
System.out.println(String.format("USAGE: java -jar so-downloader.jar <source-URL> <target-filename>"));
System.exit(1);
}
String sourceUrl = args[0];
String targetFilename = args[1];
long bytesDownloaded = download(sourceUrl, targetFilename);
System.out.println(String.format("Downloaded %d bytes from %s to %s.", bytesDownloaded, sourceUrl, targetFilename));
}
static long download(String sourceUrl, String targetFileName) throws MalformedURLException, IOException {
try (InputStream in = URI.create(sourceUrl).toURL().openStream()) {
return Files.copy(in, Paths.get(targetFileName));
}
}
}
As noted in the so-downloader repository README:
To run file download program:
java -jar so-downloader.jar <source-URL> <target-filename>
for example:
java -jar so-downloader.jar https://github.com/JanStureNielsen/so-downloader/archive/main.zip so-downloader-source.zip

Swift 4 Solution-
Use this function
func image(with image: UIImage, scaledTo newSize: CGSize) -> UIImage {
UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
image.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
drawingImageView.image = newImage
return newImage ?? UIImage()
}
Calling a function:-
image(with: predictionImage, scaledTo: CGSize(width: 28.0, height: 28.0)
here 28.0 is the pixel size that you want to set

With Inputmode you can give a hint to the browser.
I would like to mention a PRETTY COOL feature that has been included since iOS 10, which is:
For now, UIRefreshControl is directly supported in each of UICollectionView
, UITableView
and UIScrollView
!
Each one of these views have refreshControl instance property, which means that there is no longer a need to add it as a subview in your scroll view, all you have to do is:
@IBOutlet weak var collectionView: UICollectionView!
override func viewDidLoad() {
super.viewDidLoad()
let refreshControl = UIRefreshControl()
refreshControl.addTarget(self, action: #selector(doSomething), for: .valueChanged)
// this is the replacement of implementing: "collectionView.addSubview(refreshControl)"
collectionView.refreshControl = refreshControl
}
func doSomething(refreshControl: UIRefreshControl) {
print("Hello World!")
// somewhere in your code you might need to call:
refreshControl.endRefreshing()
}
Personally, I find it more natural to treat it as a property for scroll view more than add it as a subview, especially because the only appropriate view to be as a superview for a UIRefreshControl is a scrollview, i.e the functionality of using UIRefreshControl is only useful when working with a scroll view; That's why this approach should be more obvious to setup the refresh control view.
However, you still have the option of using the addSubview
based on the iOS version:
if #available(iOS 10.0, *) {
collectionView.refreshControl = refreshControl
} else {
collectionView.addSubview(refreshControl)
}
at
and operator[]
both return a reference to the indexed element, so you can simply use:
l.at(4) = -1;
or
l[4] = -1;
To me, the primary difference to choose BeanFactory
over ApplicationContext
seems to be that ApplicationContext
will pre-instantiate all of the beans. From the Spring docs:
Spring sets properties and resolves dependencies as late as possible, when the bean is actually created. This means that a Spring container which has loaded correctly can later generate an exception when you request an object if there is a problem creating that object or one of its dependencies. For example, the bean throws an exception as a result of a missing or invalid property. This potentially delayed visibility of some configuration issues is why ApplicationContext implementations by default pre-instantiate singleton beans. At the cost of some upfront time and memory to create these beans before they are actually needed, you discover configuration issues when the ApplicationContext is created, not later. You can still override this default behavior so that singleton beans will lazy-initialize, rather than be pre-instantiated.
Given this, I initially chose BeanFactory
for use in integration/performance tests since I didn't want to load the entire application for testing isolated beans. However -- and somebody correct me if I'm wrong -- BeanFactory
doesn't support classpath
XML configuration. So BeanFactory
and ApplicationContext
each provide a crucial feature I wanted, but neither did both.
Near as I can tell, the note in the documentation about overriding default instantiation behavior takes place in the configuration, and it's per-bean, so I can't just set the "lazy-init" attribute in the XML file or I'm stuck maintaining a version of it for test and one for deployment.
What I ended up doing was extending ClassPathXmlApplicationContext
to lazily load beans for use in tests like so:
public class LazyLoadingXmlApplicationContext extends ClassPathXmlApplicationContext {
public LazyLoadingXmlApplicationContext(String[] configLocations) {
super(configLocations);
}
/**
* Upon loading bean definitions, force beans to be lazy-initialized.
* @see org.springframework.context.support.AbstractXmlApplicationContext#loadBeanDefinitions(org.springframework.beans.factory.xml.XmlBeanDefinitionReader)
*/
@Override
protected void loadBeanDefinitions(XmlBeanDefinitionReader reader) throws IOException {
super.loadBeanDefinitions(reader);
for (String name: reader.getBeanFactory().getBeanDefinitionNames()) {
AbstractBeanDefinition beanDefinition = (AbstractBeanDefinition) reader.getBeanFactory().getBeanDefinition(name);
beanDefinition.setLazyInit(true);
}
}
}
Your select statement is returning a sequence of anonymous type , not a sequence of DataRows. CopyToDataTable() is only available on IEnumerable<T>
where T
is or derives from DataRow
. You can select r
the row object to call CopyToDataTable on it.
var query = from r in matrix.AsEnumerable()
where r.Field<string>("c_to") == c_to &&
r.Field<string>("p_to") == p_to
select r;
DataTable conversions = query.CopyToDataTable();
You can also implement CopyToDataTable Where the Generic Type T Is Not a DataRow.
Well, you have to iterate through your abstract type Foo and that depends on the methods available on that object. You don't have to loop through the ArrayList because this object grows automatically in Java. (Don't confuse it with an array in other programming languages)
Recommended reading. Lists in the Java Tutorial
Yes, Just be careful if you are also iterating over the list, because in this case you will need to synchronize on it. From the Javadoc:
It is imperative that the user manually synchronize on the returned list when iterating over it:
List list = Collections.synchronizedList(new ArrayList());
...
synchronized (list) {
Iterator i = list.iterator(); // Must be in synchronized block
while (i.hasNext())
foo(i.next());
}
Or, you can use CopyOnWriteArrayList
which is slower for writes but doesn't have this issue.
Next pattern is used in K-9 mail:
public static final Pattern EMAIL_ADDRESS_PATTERN = Pattern.compile(
"[a-zA-Z0-9\\+\\.\\_\\%\\-\\+]{1,256}" +
"\\@" +
"[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}" +
"(" +
"\\." +
"[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25}" +
")+"
);
You can use function
private boolean checkEmail(String email) {
return EMAIL_ADDRESS_PATTERN.matcher(email).matches();
}
I've found two ways to refresh PHP content:
1. Using the HTML meta
tag:
echo("<meta http-equiv='refresh' content='1'>"); //Refresh by HTTP 'meta'
2. Using PHP refresh rate:
$delay = 0; // Where 0 is an example of a time delay. You can use 5 for 5 seconds, for example!
header("Refresh: $delay;");
You can not "attach" a SASS/SCSS file to an HTML document.
SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.
There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.
It's as simple as adding 2 lines of code to your HTML file.
<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>
AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.
As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.
So AArch64 and ARM64 refer to the same thing.
You could also try SAP's Data Quality solutions which are available in both a server platform is processing a large number of requests or as an embeddable SDK if you wanted to run it in process with your application. We use it in our application and it's very robust and scalable.
Try the following -
var FullUrl = Request.Url.AbsolutePath.ToString();
var ID = FullUrl.Split('/').Last();
Components should start with capital letters. Also remember to change the first letter in the line to export!
For those looking to execute shell commands in a git alias, for example:
$ git pof
In my terminal will push force the current branch to my origin repo:
[alias]
pof = !git push origin -f $(git branch | grep \\* | cut -d ' ' -f2)
Where the
$(git branch | grep \\* | cut -d ' ' -f2)
command returns the current branch.
So this is a shortcut for manually typing the branch name:
git push origin -f <current-branch>
You can also create a new jsp file sayng that form is submited and in your main action file just write its file name
Eg. Your form is submited is in a file succes.jsp Then your action file will have
Request.sendRedirect("success.jsp")
As above mentioned, there is no special command to do it. However, if all those connection are inactive, using 'flush tables;' is able to release all those connection which are not active.
I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me
find . -name one.pdf -o -name two.txt -o -name anotherone.jpg
-o
or -or
is logical OR. See Finding Files on Gnu.org for more information.
I was running this on CygWin.
I always used a couple lines of code which clear the input stream of any characters and then wait for input to ignore.
Something like:
void pause() {
cin.clear();
cout << endl << "Press any key to continue...";
cin.ignore();
}
And then any time I need it in the program I have my own pause(); function, without the overhead of a system pause. This is only really an issue when writing console programs that you want to stay open or stay fixated on a certain point though.
Another way by using ajax method:
View:
@Html.TextBox("txtValue", null, new { placeholder = "Input value" })
<input type="button" value="Start" id="btnStart" />
<script>
$(function () {
$('#btnStart').unbind('click');
$('#btnStart').on('click', function () {
$.ajax({
url: "/yourControllerName/yourMethod",
type: 'POST',
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: JSON.stringify({
txtValue: $("#txtValue").val()
}),
async: false
});
});
});
</script>
Controller:
[HttpPost]
public EmptyResult YourMethod(string txtValue)
{
// do what you want with txtValue
...
}
I've used these codes:
HTML:
<a id="delete-button">Delete</a>
jQuery:
<script>
$("#delete-button").click(function(){
if(confirm("Are you sure you want to delete this?")){
$("#delete-button").attr("href", "query.php?ACTION=delete&ID='1'");
}
else{
return false;
}
});
</script>
These codes works for me, but I'm not really sure if this is proper. What do you think?
I recommend that you try to use Postgres.app. (http://postgresapp.com)
This way you can easily turn Postgres on and off on your Mac.
Once you do, add the path to Postgres to your .profile
file by appending the following:
PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"
Only after you added Postgres to your path you can try to install psycopg2
either within a virtual environment (using pip) or into your global site packages.

This creates valid xlsx on the client side. Also supports some basic styling. Check https://codepen.io/rohithb/pen/YdjVbb for a working example.
In the terminal just write : $ mongod --version
Here it goes an example:
$.post("test.php", { 'choices[]': ["Jon", "Susan"] });
Hope it helps.

One thing that (surprisingly) hasn't been mentioned is that a request can explicitly indicate that it will accept stale data, using the max-stale
directive. In that case, if the server responded with max-age=0
, the cache would merely consider the response stale, and would be free to use it to satisfy the client's request [which asked for potentially-stale data]. By contrast, if the server sends no-cache
that really does trump any request by the client (with max-stale
) for stale data, as the cache MUST revalidate.
The only one that works across IE, Firefox, chrome, safari and opera if there are no spaces in the word (such as a long URL) is:
div{
width: 200px;
word-break: break-all;
}
I found this to be bullet-proof.
For Example:
$data = array('firstKey' => 'firstValue', 'secondKey' => 'secondValue');
For changing key value:
$data['firstKey'] = 'changedValue';
//this will change value of firstKey because firstkey is available in array
output:
Array ( [firstKey] => changedValue [secondKey] => secondValue )
For adding new key value pair:
$data['newKey'] = 'newValue';
//this will add new key and value because newKey is not available in array
output:
Array ( [firstKey] => firstValue [secondKey] => secondValue [newKey] => newValue )
If you are in the console window for the device and if you use Teraterm, then from the Menu do a File | Log and it will automatically save to file.
This code works well for returning all of the IP addresses that might belong to a particular URI. Since many systems are now in a hosted environment (AWS/Akamai/etc.), systems may return several IP addresses. The lambda was "borrowed" from @Peter Silva.
def get_ips_by_dns_lookup(target, port=None):
'''
this function takes the passed target and optional port and does a dns
lookup. it returns the ips that it finds to the caller.
:param target: the URI that you'd like to get the ip address(es) for
:type target: string
:param port: which port do you want to do the lookup against?
:type port: integer
:returns ips: all of the discovered ips for the target
:rtype ips: list of strings
'''
import socket
if not port:
port = 443
return list(map(lambda x: x[4][0], socket.getaddrinfo('{}.'.format(target),port,type=socket.SOCK_STREAM)))
ips = get_ips_by_dns_lookup(target='google.com')
In my case, I missed to write @JsonProperty annotation in one of the fields which was causing this error.
there might be a problem at your web hosting company from where you are testing the secure communication for gateway, that they might not allow you to do that.
also there might be a username, password that must be provided before connecting to remote host.
or your IP might need to be in the list of approved IP for the remote server for communication to initiate.

You can call tail +[line number] [file]
and pipe it to grep -n
which shows the line number:
tail +[line number] [file] | grep -n /regex/
The only problem with this method is the line numbers reported by grep -n
will be [line number] - 1
less than the actual line number in [file]
.
If .xlsx
file has many sheets, -s
flag can be used to get the sheet you want. For example:

For those experimenting with this in phpMyAdmin, just a word:
phpMyAdmin appears to have a few problems with USING
. For the record this is phpMyAdmin run on Linux Mint, version: "4.5.4.1deb2ubuntu2", Database server: "10.2.14-MariaDB-10.2.14+maria~xenial - mariadb.org binary distribution".
I have run SELECT
commands using JOIN
and USING
in both phpMyAdmin and in Terminal (command line), and the ones in phpMyAdmin produce some baffling responses:
1) a LIMIT
clause at the end appears to be ignored.
2) the supposed number of rows as reported at the top of the page with the results is sometimes wrong: for example 4 are returned, but at the top it says "Showing rows 0 - 24 (2503 total, Query took 0.0018 seconds.)"
Logging on to mysql normally and running the same queries does not produce these errors. Nor do these errors occur when running the same query in phpMyAdmin using JOIN ... ON ...
. Presumably a phpMyAdmin bug.
Simple solution
setcookie("NAME", "VALUE", time()+3600, '/', EXAMPLE.COM);
Setcookie's 5th parameter determines the (sub)domains that the cookie is available to. Setting it to (EXAMPLE.COM) makes it available to any subdomain (eg: SUBDOMAIN.EXAMPLE.COM )

In as few words as possible:
A variable cannot be both null
and undefined
at the same time. However, the direct answer to your question is:
if (variable != null)
One =
, not two.
There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null
and the other being undefined
, and the result is true
for ==
and false
for !=
. Thus if the value of the variable is undefined
, it's not != null
, and if it's not null, it's obviously not != null
.
Now, the case of an identifier not being defined at all, either as a var
or let
, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:
var isDefined = false;
try {
(variable);
isDefined = true;
}
catch (x) {}
I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window
property (in browser JavaScript):
var isJqueryAvailable = window.jQuery != null;
or
var isJqueryAvailable = "jQuery" in window;
You may use conditional compilation:
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
#if SOME_BUILD_FLAG_A
.AddJsonFile($"appsettings.flag_a.json", optional: true)
#else
.AddJsonFile($"appsettings.no_flag_a.json", optional: true)
#endif
.AddEnvironmentVariables();
this.configuration = builder.Build();
}
Use screen. It is very simple to use and works like vnc for terminals. http://www.bangmoney.org/presentations/screen.html
Either use window.onload
this way
<script>
window.onload = function() {
// ...
}
</script>
or alternatively
<script>
window.onload = functionName;
</script>
(yes, without the parentheses)
Or just put the script at the very bottom of page, right before </body>
. At that point, all HTML DOM elements are ready to be accessed by document
functions.
<body>
...
<script>
functionName();
</script>
</body>
A good way to debug this is the next time it happens, SSH into the remote repo, cd into the objects folder and do an ls -al
.
If you see 2-3 files with different user:group ownership than this is the problem.
It's happened to me in the past with some legacy scripts access our git repo and usually means a different (unix) user pushed / modified files last and your user doesn't have permissions to overwrite those files. You should create a shared git group that all git-enabled users are in and then recursively chgrp
the objects
folder and it's contents so that it's group ownership is the shared git
group.
You should also add a sticky bit on the folder so that all the files created in the folder will always have the group of git
.
chmod g+s directory-name
Update: I didn't know about core.sharedRepository. Good to know, though it probably just does the above.
The issue might be to do with your server configuration - it may not be sending the right headers for the font files. Take a look at the answer given for the question IE9 blocks download of cross-origin web font.
EricLaw suggests adding the following to your Apache config
<FilesMatch "\.(ttf|otf|eot|woff)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "http://mydomain.com"
</IfModule>
</FilesMatch>
My approach was, but I can't guarantee that this is the fastest solution.
df = pd.DataFrame(columns=["firstname", "lastname"])
df = df.append({
"firstname": "John",
"lastname": "Johny"
}, ignore_index=True)
For those whose want created or modified user detail along with the time using JPA and Spring Data can follow this. You can add @CreatedDate
,@LastModifiedDate
,@CreatedBy
and @LastModifiedBy
in the base domain. Mark the base domain with @MappedSuperclass
and @EntityListeners(AuditingEntityListener.class)
like shown below:
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class BaseDomain implements Serializable {
@CreatedDate
private Date createdOn;
@LastModifiedDate
private Date modifiedOn;
@CreatedBy
private String createdBy;
@LastModifiedBy
private String modifiedBy;
}
Since we marked the base domain with AuditingEntityListener
we can tell JPA about currently logged in user. So we need to provide an implementation of AuditorAware and override getCurrentAuditor()
method. And inside getCurrentAuditor()
we need to return the currently authorized user Id.
public class AuditorAwareImpl implements AuditorAware<String> {
@Override
public Optional<String> getCurrentAuditor() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
return authentication == null ? Optional.empty() : Optional.ofNullable(authentication.getName());
}
}
In the above code if Optional
is not working you may using older spring data. In that case try changing Optional
with String
.
Now for enabling the above Audtior implementation use the code below
@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class JpaConfig {
@Bean
public AuditorAware<String> auditorAware() {
return new AuditorAwareImpl();
}
}
Now you can extend the BaseDomain
class to all of your entity class where you want the created and modified date & time along with user Id
Nginx-extra package is deprecated now.
The following therefore did now work for me as i tried installing various packages more_set_headers 'Server: My Very Own Server';
You can just do the following and no server or version information will be sent back
server_tokens '';
if you just want to remove the version number this works
server_tokens off;
Using standard java libs, I suggest looking at the HttpUrlConnection class http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html
It can handle most of what curl can do with setting up the connection. What you do with the stream is up to you.
Will return a floating point number in the range [0,1]:
#define rand01() (((double)random())/((double)(RAND_MAX)))
Below code may help you to achieve session attribution inside java script:
var name = '<%= session.getAttribute("username") %>';
maybe because it not supports code highlights inside scriplets. not sure though.
You can try using one of the eclipse plugin like 'glance search' which works great. Here's a link for that- http://code.google.com/p/eclipse-glance/
You do not need to use {{ }} inside of ng-bind-html-unsafe:
<div ng-bind-html-unsafe="preview_data.preview.embed.html"></div>
Here's an example: http://plnkr.co/edit/R7JmGIo4xcJoBc1v4iki?p=preview
The {{ }} operator is essentially just a shorthand for ng-bind, so what you were trying amounts to a binding inside a binding, which doesn't work.
@MykolaGolubyev has already given wonderful explanation. I was looking for a solution to do somthing like this MyClass obj ( MyAnotherClass() )
but the compiler was interpreting it as a function declaration.
C++11 has braced-init-list. Using this we can do something like this
Temp t{String()};
However, this:
Temp t(String());
throws compilation error as it considers t
as of type Temp(String (*)())
.
#include <iostream>
class String {
public:
String(const char* str): ptr(str)
{
std::cout << "Constructor: " << str << std::endl;
}
String(void): ptr(nullptr)
{
std::cout << "Constructor" << std::endl;
}
virtual ~String(void)
{
std::cout << "Destructor" << std::endl;
}
private:
const char *ptr;
};
class Temp {
public:
Temp(String in): str(in)
{
std::cout << "Temp Constructor" << std::endl;
}
Temp(): str(String("hello"))
{
std::cout << "Temp Constructor: 2" << std::endl;
}
virtual ~Temp(void)
{
std::cout << "Temp Destructor" << std::endl;
}
virtual String get_str()
{
return str;
}
private:
String str;
};
int main(void)
{
Temp t{String()}; // Compiles Success!
// Temp t(String()); // Doesn't compile. Considers "t" as of type: Temp(String (*)())
t.get_str(); // dummy statement just to check if we are able to access the member
return 0;
}
Today, I have used this feature, so here's my very fresh real-life example. (I have changed class and method names to generic ones so they won't distract from the actual point.)
I have a method that's meant to accept a Set
of A
objects that I originally wrote with this signature:
void myMethod(Set<A> set)
But it want to actually call it with Set
s of subclasses of A
. But this is not allowed! (The reason for that is, myMethod
could add objects to set
that are of type A
, but not of the subtype that set
's objects are declared to be at the caller's site. So this could break the type system if it were possible.)
Now here come generics to the rescue, because it works as intended if I use this method signature instead:
<T extends A> void myMethod(Set<T> set)
or shorter, if you don't need to use the actual type in the method body:
void myMethod(Set<? extends A> set)
This way, set
's type becomes a collection of objects of the actual subtype of A
, so it becomes possible to use this with subclasses without endangering the type system.
First, ask the program to tell you what is wrong by checking the errno
, which is set on failure, such as during fseek
or ftell
.
Others (tonio & LatinSuD) have explained the mistake with handling stdin versus checking for a filename. Namely, first check argc
(argument count) to see if there are any command line parameters specified if (argc > 1)
, treating -
as a special case meaning stdin
.
If no parameters are specified, then assume input is (going) to come from stdin
, which is a stream not file, and the fseek
function fails on it.
In the case of a stream, where you cannot use file-on-disk oriented library functions (i.e. fseek
and ftell
), you simply have to count the number of bytes read (including trailing newline characters) until receiving EOF (end-of-file).
For usage with large files you could speed it up by using fgets
to a char array for more efficient reading of the bytes in a (text) file. For a binary file you need to use fopen(const char* filename, "rb")
and use fread
instead of fgetc/fgets
.
You could also check the for feof(stdin)
/ ferror(stdin)
when using the byte-counting method to detect any errors when reading from a stream.
The sample below should be C99 compliant and portable.
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
long getSizeOfInput(FILE *input){
long retvalue = 0;
int c;
if (input != stdin) {
if (-1 == fseek(input, 0L, SEEK_END)) {
fprintf(stderr, "Error seek end: %s\n", strerror(errno));
exit(EXIT_FAILURE);
}
if (-1 == (retvalue = ftell(input))) {
fprintf(stderr, "ftell failed: %s\n", strerror(errno));
exit(EXIT_FAILURE);
}
if (-1 == fseek(input, 0L, SEEK_SET)) {
fprintf(stderr, "Error seek start: %s\n", strerror(errno));
exit(EXIT_FAILURE);
}
} else {
/* for stdin, we need to read in the entire stream until EOF */
while (EOF != (c = fgetc(input))) {
retvalue++;
}
}
return retvalue;
}
int main(int argc, char **argv) {
FILE *input;
if (argc > 1) {
if(!strcmp(argv[1],"-")) {
input = stdin;
} else {
input = fopen(argv[1],"r");
if (NULL == input) {
fprintf(stderr, "Unable to open '%s': %s\n",
argv[1], strerror(errno));
exit(EXIT_FAILURE);
}
}
} else {
input = stdin;
}
printf("Size of file: %ld\n", getSizeOfInput(input));
return EXIT_SUCCESS;
}
As mentioned, Selenium is a good choice for rendering the results of the JavaScript:
from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
browser = Firefox(executable_path="/usr/local/bin/geckodriver", options=options)
url = "https://www.example.com"
browser.get(url)
And gazpacho is a really easy library to parse over the rendered html:
from gazpacho import Soup
soup = Soup(browser.page_source)
soup.find("a").attrs['href']
The Array index only accepts a long value.
You declared iCounter as an integer. You should declare it as a long.
ghost activity called with singletop and finish() on onCreate should do the trick
"%s"
will read the input until whitespace is reached.
gets might be a good place to start if you want to read a line (i.e. all characters including whitespace until a newline character is reached).

I don't know about targeting iOS as a whole, but to target iOS Safari specifically:
@supports (-webkit-touch-callout: none) {
/* CSS specific to iOS devices */
}
@supports not (-webkit-touch-callout: none) {
/* CSS for other than iOS devices */
}
Apparently as of iOS 13 -webkit-overflow-scrolling
no longer responds to @supports
, but -webkit-touch-callout
still does. Of course that could change in the future...
"Casting" is different than conversion. In this case, window.location.hash
will auto-convert a number to a string. But to avoid a TypeScript compile error, you can do the string conversion yourself:
window.location.hash = ""+page_number;
window.location.hash = String(page_number);
These conversions are ideal if you don't want an error to be thrown when page_number
is null
or undefined
. Whereas page_number.toString()
and page_number.toLocaleString()
will throw when page_number
is null
or undefined
.
When you only need to cast, not convert, this is how to cast to a string in TypeScript:
window.location.hash = <string>page_number;
// or
window.location.hash = page_number as string;
The <string>
or as string
cast annotations tell the TypeScript compiler to treat page_number
as a string at compile time; it doesn't convert at run time.
However, the compiler will complain that you can't assign a number to a string. You would have to first cast to <any>
, then to <string>
:
window.location.hash = <string><any>page_number;
// or
window.location.hash = page_number as any as string;
So it's easier to just convert, which handles the type at run time and compile time:
window.location.hash = String(page_number);
(Thanks to @RuslanPolutsygan for catching the string-number casting issue.)
Does an implicit conversion occur between Task<> and int?
Nope. This is just part of how async
/await
works.
Any method declared as async
has to have a return type of:
void
(avoid if possible)Task
(no result beyond notification of completion/failure)Task<T>
(for a logical result of type T
in an async manner)The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length
- you can't make the method just return int
, as the actual method will return when it hits the first await
expression which hasn't already completed. So instead, it returns a Task<int>
which will complete when the async method itself completes.
Note that await
does the opposite - it unwraps a Task<T>
to a T
value, which is how this line works:
string urlContents = await getStringTask;
... but of course it unwraps it asynchronously, whereas just using Result
would block until the task had completed. (await
can unwrap other types which implement the awaitable pattern, but Task<T>
is the one you're likely to use most often.)
This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:
public async Task<int> AccessTheWebAndDoubleAsync()
{
var task = AccessTheWebAsync();
int result = await task;
return result * 2;
}
(Or simply return await AccessTheWebAsync() * 2;
of course.)
Assuming you're referring to MS-DOS batch files: as it is simply a text file with a special extension, a .bat
file doesn't store an icon of its own.
You can, however, create a shortcut in the .lnk
format that stores an icon.
Using Java 8+ lambda expressions, if you have a class or interface with only a single abstract method (sometimes called a SAM type), for example:
public interface MyInterface {
String doSomething(int param1, String param2);
}
then anywhere where MyInterface is used, you can substitute a lambda expression:
class MyClass {
public MyInterface myInterface = (p1, p2) -> { return p2 + p1; };
}
For example, you can create a new thread very quickly:
new Thread(() -> someMethod()).start();
And use the method reference syntax to make it even cleaner:
new Thread(this::someMethod).start();
Without lambda expressions, these last two examples would look like:
new Thread(new Runnable() { someMethod(); }).start();
A common pattern would be to 'wrap' it within an interface, like Callable
, for example, then you pass in a Callable:
public T myMethod(Callable<T> func) {
return func.call();
}
This pattern is known as the Command Pattern.
Keep in mind you would be best off creating an interface for your particular usage. If you chose to go with callable, then you'd replace T above with whatever type of return value you expect, such as String.
In response to your comment below you could say:
public int methodToPass() {
// do something
}
public void dansMethod(int i, Callable<Integer> myFunc) {
// do something
}
then call it, perhaps using an anonymous inner class:
dansMethod(100, new Callable<Integer>() {
public Integer call() {
return methodToPass();
}
});
Keep in mind this is not a 'trick'. It's just java's basic conceptual equivalent to function pointers.
You seem to misunderstand the box model - in CSS you provide points for the top and left and then width and height - these are all that are needed for a box to be placed with exact measurements.
The width
property is what your C-D
is, but it is also what A-B
is. If you omit it, the div will not have a defined width and the width will be defined by its contents.
Update (following the comments on the question:
Add a border-bottom-style: none;
to your CSS to remove this style from the bottom only.
Find below 3 methods:
Checking page readyState (not reliable):
def page_has_loaded(self):
self.log.info("Checking if {} page is loaded.".format(self.driver.current_url))
page_state = self.driver.execute_script('return document.readyState;')
return page_state == 'complete'
The
wait_for
helper function is good, but unfortunatelyclick_through_to_new_page
is open to the race condition where we manage to execute the script in the old page, before the browser has started processing the click, andpage_has_loaded
just returns true straight away.
id
Comparing new page ids with the old one:
def page_has_loaded_id(self):
self.log.info("Checking if {} page is loaded.".format(self.driver.current_url))
try:
new_page = browser.find_element_by_tag_name('html')
return new_page.id != old_page.id
except NoSuchElementException:
return False
It's possible that comparing ids is not as effective as waiting for stale reference exceptions.
staleness_of
Using staleness_of
method:
@contextlib.contextmanager
def wait_for_page_load(self, timeout=10):
self.log.debug("Waiting for page to load at {}.".format(self.driver.current_url))
old_page = self.find_element_by_tag_name('html')
yield
WebDriverWait(self, timeout).until(staleness_of(old_page))

If you are not get that at localhost either production, that means you must upgrade your plan due to the limitations of the free tier
Even shorter version of the solution from Dominic Zukiewicz:
ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;
But this means that you will trust all certificates. For a service that isn't just run locally, something a bit smarter will be needed. In the first instance you could use this code to just test whether it solves your problem.
before going for the step "compile -DIPLIB=NONE filename.cxx" take the path of VIsual Studio installation upto the vcvarsall batch file and change the configuration as shown below.
*C:\apps\MVS9\VC\vcvarsall.bat x86_amd64*
now next step should be
compile -64bit -DIPLIB=none filename.cxx
this solved the problem for me
You could also disinherit all transitions inside a containing element:
CSS:
.noTrans *{
-moz-transition: none;
-webkit-transition: none;
-o-transition: color 0 ease-in;
transition: none;
}
HTML:
<a href="#">Content</a>
<a href="#">Content</a>
<div class="noTrans">
<a href="#">Content</a>
</div>
<a href="#">Content</a>
The answers here are straightforward but only apply to a 1 dimensional array. For multi-dimensional arrays, checking for null is a straightforward way to tell if the element exists. Example code here checks for null. Note the try/catch block is [probably] overkill but it makes the block bomb-proof.
public ItemContext GetThisElement(int row,
int col)
{
ItemContext ctx = null;
if (rgItemCtx[row, col] != null)
{
try
{
ctx = rgItemCtx[row, col];
}
catch (SystemException sex)
{
ctx = null;
// perhaps do something with sex properties
}
}
return (ctx);
}
If its only the cluttering what gives the problem in the constructor
why not implement a initialize
method that intializes
the variables. This is a normal thing to do when the constructor gets to full with unnecessary stuff. Even in typed program languages like C#
its normal convention to add an Initialize
method to handle that.

Say A:A contains the post codes, you could add a B column and put a 1 in each cell. In C1, put =SUMIF(A:A, A1, B:B) and Drag it down your sheet. That would give you the first desired result listed in your question.
EDIT: As Corey pointed out, you can just use COUNTIF(A:A, A1). As I mentioned in the comments you can copy paste special the row with formulas to hard code the counts, the select column A and click remove duplicates (entire row) to get your ideal result.
You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.
In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.
I also wanted to create OPEN SSL for Windows 10. An easy way of getting it done without running into a risk of installing unknown software from 3rd party websites and risking entries of viruses, is by using the openssl.exe
that comes inside your Git for Windows installation. In my case, I found the open SSL in the following location of Git for Windows Installation.
C:\Program Files\Git\usr\bin\openssl.exe
If you also want instructions on how to use OPENSSL to generate and use Certificates. Here is a write-up on my blog. The step by step instructions first explains how to use Microsoft Windows Default Tool and also OPEN SSL and explains the difference between them.

If you are confident in your input parameters, you can use this single line of code which uses the native Split and Join functions and Excel native Application.pathSeparator.
Split(Join(Split(strPath, "."), Application.pathSeparator), Application.pathSeparator)
If you want a more extensive function, the code below is tested in Windows and should also work on Mac (though not tested). Be sure to also copy the supporting function GetPathSeparator, or modify the code to use Application.pathSeparator. Note, this is a first draft; I should really refactor it to be more concise.

To add yet another reason to the list ... in my case I found this problem was being caused by an SELinux permissions problem on the server. This is worth checking if your server is running Fedora / CentOS / Red Hat. To test this scenario you can run:
Client: ssh -vT git@<gitlab-server>
-- asks for password
Server: sudo setenforce 0
Client: ssh -vT git@<gitlab-server>
-- succeeds
Server: sudo setenforce 1
In my case the gitlab/git user's authorized_keys
file had the wrong SELinux file context, and the ssh service was being denied permission to read it. I fixed this on the server side as follows:
sudo semanage fcontext -a -t ssh_home_t /gitlab/.ssh/
sudo semanage fcontext -a -t ssh_home_t /gitlab/.ssh/authorized_keys
sudo restorecon -F -Rv /gitlab/.ssh/
And I was then able to git clone
on the client side as expected.

Just a tip. Works on firefox only
I created a jQuery plugin that uses Bootstrap's tooltip instead of the browser's build-in tooltip. Please note that this has not been tested with older browser.
JSFiddle: https://jsfiddle.net/0bhsoavy/4/
$.fn.tooltipOnOverflow = function(options) {
$(this).on("mouseenter", function() {
if (this.offsetWidth < this.scrollWidth) {
options = options || { placement: "auto"}
options.title = $(this).text();
$(this).tooltip(options);
$(this).tooltip("show");
} else {
if ($(this).data("bs.tooltip")) {
$tooltip.tooltip("hide");
$tooltip.removeData("bs.tooltip");
}
}
});
};
I found another solution for renaming a package in the entire project:
Open a file in the package. IntelliJ displays the breadcrumbs of the file, above the opened file. On the package you want renamed: Right click > Refactor > Rename. This renames the package/directory throughout the entire project.
If you have a table with this exact record layout, use its name as a type, otherwise you will have to declare the type explicitly:
CREATE OR REPLACE FUNCTION get_object_fields
(
name text
)
RETURNS mytable
AS
$$
DECLARE f1 INT;
DECLARE f2 INT;
…
DECLARE f8 INT;
DECLARE retval mytable;
BEGIN
-- fetch fields f1, f2 and f3 from table t1
-- fetch fields f4, f5 from table t2
-- fetch fields f6, f7 and f8 from table t3
retval := (f1, f2, …, f8);
RETURN retval;
END
$$ language plpgsql;
myisam is a NOGO for that type of workload (high concurrency writes), i dont have that much experience with innodb (tested it 3 times and found in each case that the performance sucked, but it's been a while since the last test) if you're not forced to run mysql, consider giving postgres a try as it handles concurrent writes MUCH better

This is likely caused by your application's connection pool; not an Oracle DBMS issue. Most connection pools have a validate statement that can execute before giving you the connection. In oracle you would want "Select 1 from dual".
The reason it started occurring after you restarted the server is that the connection pool was probably added without a restart and you are just now experiencing the use of the connection pool for the first time. What is the modification dates on your resource files that deal with database connections?
Validate Query example:
<Resource name="jdbc/EmployeeDB" auth="Container"
validationQuery="Select 1 from dual" type="javax.sql.DataSource" username="dbusername" password="dbpassword"
driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"
maxActive="8" maxIdle="4"/>
EDIT: In the case of Grails, there are similar configuration options for the grails pool. Example for Grails 1.2 (see release notes for Grails 1.2)
dataSource {
pooled = true
dbCreate = "update"
url = "jdbc:mysql://localhost/yourDB"
driverClassName = "com.mysql.jdbc.Driver"
username = "yourUser"
password = "yourPassword"
properties {
maxActive = 50
maxIdle = 25
minIdle = 5
initialSize = 5
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
maxWait = 10000
}
}
in my case, i was using the change command like this way
$(document).on('change', '.select-brand', function () {...my codes...});
and then i changed the way to
$('.select-brand').on('change', function () {...my codes...});
and it solved my problem.
Given points (X1,Y1) and (X2,Y2) then:
dX = X1 - X2;
dY = Y1 - Y2;
if (dX*dX + dY*dY > (5*5))
{
//your code
}
You have to be very careful about the method names. In this case, the method name is just "lowercaseString
", not "lowercaseString:
" (note the absence of the colon). That's why you're getting NO
returned, because NSString
objects respond to the lowercaseString
message but not the lowercaseString:
message.
How do you know when to add a colon? You add a colon to the message name if you would add a colon when calling it, which happens if it takes one argument. If it takes zero arguments (as is the case with lowercaseString
), then there is no colon. If it takes more than one argument, you have to add the extra argument names along with their colons, as in compare:options:range:locale:
.
You can also look at the documentation and note the presence or absence of a trailing colon.
As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &
. That also requires using parentheses so that &
wouldn't take precedence.
It would go something like this:
mask = ((50 < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...
In order to avoid that, you can build series for lower and upper limits:
low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)
Now you can slice it as follows:
mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]
Out:

And for assignment you can use np.where:
df['class'] = np.where(mask, 'excellent', 'critical')
There are 3 ways to allow cross domain origin (excluding jsonp
):
1) Set the header in the page directly using a templating language like PHP. Keep in mind there can be no HTML before your header or it will fail.
<?php header("Access-Control-Allow-Origin: http://example.com"); ?>
2) Modify the server configuration file (apache.conf
) and add this line. Note that "*"
represents allow all. Some systems might also need the credential set. In general allow all access is a security risk and should be avoided:
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials true
3) To allow multiple domains on Apache web servers add the following to your config file
<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www\.)?(example.org|example.com)$" AccessControlAllowOrigin=$0$1
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true
</IfModule>
4) For development use only hack your browser and allow unlimited CORS using the Chrome Allow-Control-Allow-Origin extension
5) Disable CORS in Chrome: Quit Chrome completely. Open a terminal and execute the following. Just be cautious you are disabling web security:
open -a Google\ Chrome --args --disable-web-security --user-data-dir
The original variables you listed can be declared and assigned to the same value in a short line of code using destructuring assignment. The keywords let
, const
, and var
can all be used for this type of assignment.
let [moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown] = Array(6).fill(false);
I think you are asking about code like this.
int count = (request.getParameter("counter") == null) ? 0 : Integer.parseInt(request.getParameter("counter"));
This should do it for you:
new_list = list(set(old_list))
set
will automatically remove duplicates. list
will cast it back to a list.
Just Override the boolean equals() method of custom object. Say you have an ArrayList with custom field f1, f2, ... override
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof CustomObject)) return false;
CustomObject object = (CustomObject) o;
if (!f1.equals(object.dob)) return false;
if (!f2.equals(object.fullName)) return false;
...
return true;
}
and check using ArrayList instance's contains() method. That's it.
While trace flag 272 may work for many, it definitely won't work for hosted Sql Server Express installations. So, I created an identity table, and use this through an INSTEAD OF trigger. I'm hoping this helps someone else, and/or gives others an opportunity to improve my solution. The last line allows returning the last identity column added. Since I typically use this to add a single row, this works to return the identity of a single inserted row.
The identity table:
CREATE TABLE [dbo].[tblsysIdentities](
[intTableId] [int] NOT NULL,
[intIdentityLast] [int] NOT NULL,
[strTable] [varchar](100) NOT NULL,
[tsConcurrency] [timestamp] NULL,
CONSTRAINT [PK_tblsysIdentities] PRIMARY KEY CLUSTERED
(
[intTableId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
and the insert trigger:
-- INSERT --
IF OBJECT_ID ('dbo.trgtblsysTrackerMessagesIdentity', 'TR') IS NOT NULL
DROP TRIGGER dbo.trgtblsysTrackerMessagesIdentity;
GO
CREATE TRIGGER trgtblsysTrackerMessagesIdentity
ON dbo.tblsysTrackerMessages
INSTEAD OF INSERT AS
BEGIN
DECLARE @intTrackerMessageId INT
DECLARE @intRowCount INT
SET @intRowCount = (SELECT COUNT(*) FROM INSERTED)
SET @intTrackerMessageId = (SELECT intIdentityLast FROM tblsysIdentities WHERE intTableId=1)
UPDATE tblsysIdentities SET intIdentityLast = @intTrackerMessageId + @intRowCount WHERE intTableId=1
INSERT INTO tblsysTrackerMessages(
[intTrackerMessageId],
[intTrackerId],
[strMessage],
[intTrackerMessageTypeId],
[datCreated],
[strCreatedBy])
SELECT @intTrackerMessageId + ROW_NUMBER() OVER (ORDER BY [datCreated]) AS [intTrackerMessageId],
[intTrackerId],
[strMessage],
[intTrackerMessageTypeId],
[datCreated],
[strCreatedBy] FROM INSERTED;
SELECT TOP 1 @intTrackerMessageId + @intRowCount FROM INSERTED;
END
I used to use the following from CSS-Tricks:
.transparent_class {
/* IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
/* IE 5-7 */
filter: alpha(opacity=50);
/* Netscape */
-moz-opacity: 0.5;
/* Safari 1.x */
-khtml-opacity: 0.5;
/* Good browsers */
opacity: 0.5;
}
However, a better solution is to use the Opacity Compass mixin, all you need to do is to @include opacity(0.1);
and it will take care of any cross-browser issues for you. You can find an example here.
Disclaimer: This is not a solution, it is more of a hack to test out something. User-defined functions cannot be used to perform actions that modify the database state.
I found one way to make insert or update using sqlcmd.exe so you need just to replace the code inside @sql
variable.
CREATE FUNCTION [dbo].[_tmp_func](@orderID NVARCHAR(50))
RETURNS INT
AS
BEGIN
DECLARE @sql varchar(4000), @cmd varchar(4000)
SELECT @sql = 'INSERT INTO _ord (ord_Code) VALUES (''' + @orderID + ''') '
SELECT @cmd = 'sqlcmd -S ' + @@servername +
' -d ' + db_name() + ' -Q "' + @sql + '"'
EXEC master..xp_cmdshell @cmd, 'no_output'
RETURN 1
END
By current official documentation there is a short cut that stops and removes containers, networks, volumes, and images created by up, if they are already stopped or partially removed and so on, then it will do the trick too:
docker-compose down
Then if you have new changes on your images or Dockerfiles use:
docker-compose build --no-cache
Finally:docker-compose up
In one command:
docker-compose down && docker-compose build --no-cache && docker-compose up
The "netstat --programs"
command will give you the process information, assuming you're the root
user. Then you will have to kill the "offending" process which may well start up again just to annoy you.
Depending on what you're actually trying to achieve, solutions to that problem will vary based on the processes holding those ports. For example, you may need to disable services (assuming they're unneeded) or configure them to use a different port (if you do need them but you need that port more).
var column1RelArray = [];
$('#column1 li').each(function(){
column1RelArray.push($(this).attr('rel'));
});
or fp style
var column1RelArray = $('#column1 li').map(function(){
return $(this).attr('rel');
});
Old question, but my solution is a bit different.
I was writing a single page web app that was constantly making ajax calls triggered by the user, and to make it even more difficult it required libraries that used methods other than jquery (like dojo, native xhr, etc). I wrote a plugin for one of my own libraries to cache ajax requests as efficiently as possible in a way that would work in all major browsers, regardless of which libraries were being used to make the ajax call.
The solution uses jSQL (written by me - a client-side persistent SQL implementation written in javascript which uses indexeddb and other dom storage methods), and is bundled with another library called XHRCreep (written by me) which is a complete re-write of the native XHR object.
To implement all you need to do is include the plugin in your page, which is here.
There are two options:
jSQL.xhrCache.max_time = 60;
Set the maximum age in minutes. any cached responses that are older than this are re-requested. Default is 1 hour.
jSQL.xhrCache.logging = true;
When set to true, mock XHR calls will be shown in the console for debugging.
You can clear the cache on any given page via
jSQL.tables = {}; jSQL.persist();
Here is a polyglot program for BASH and Windows CMD that runs a series of commands and quits out if any of them fail:
#!/bin/bash 2> nul
:; set -o errexit
:; function goto() { return $?; }
command 1 || goto :error
command 2 || goto :error
command 3 || goto :error
:; exit 0
exit /b 0
:error
exit /b %errorlevel%
I have used this type of thing in the past for a multiple platform continuous integration script.
I bet the problem is being shown in this line
SqlDataReader dr3 = com2.ExecuteReader();
I suggest that you execute the first reader and do a dr.Close();
and the iterate historicos
, with another loop, performing the com2.ExecuteReader()
.

com = new SqlCommand(sql, conexao);
SqlDataReader dr = com.ExecuteReader();
if (dr.HasRows)

std
namespace (where features of the C++ Standard Library, such as string
or vector
, are declared).After you write this instruction, if the compiler sees string
it will know that you may be referring to std::string
, and if it sees vector
, it will know that you may be referring to std::vector
. (Provided that you have included in your compilation unit the header files where they are defined, of course.)
If you don't write it, when the compiler sees string
or vector
it will not know what you are refering to. You will need to explicitly tell it std::string
or std::vector
, and if you don't, you will get a compile error.

Following Works for me and its good from readability point of view when array element values are small:
key: [string1, string2, string3, string4, string5, string6]
Note:snakeyaml implementation used
I had the same problem with numpy arrays and the solution is to flatten them:
data = {
'b': array1.flatten(),
'a': array2.flatten(),
}
df = pd.DataFrame(data)
It depends on the context.
"undefined" means this value does not exist. typeof
returns "undefined"
"null" means this value exists with an empty value. When you use typeof
to test for "null", you will see that it's an object. Other case when you serialize "null" value to backend server like asp.net mvc, the server will receive "null", but when you serialize "undefined", the server is unlikely to receive a value.
Install from the "Unofficial Windows Binaries for Python Extension Packages"
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-dateutil
Pretty much has every package you would need.
Found it!
SELECT username,

FROM dba_users;
Loop through the list in reverse order, and use the .splice
method.
var array = ['A', 'B', 'C']; // Test
var search_term = 'B';
for (var i=array.length-1; i>=0; i--) {
if (array[i] === search_term) {
array.splice(i, 1);
// break; //<-- Uncomment if only the first term has to be removed
}
}
The reverse order is important when all occurrences of the search term has to be removed. Otherwise, the counter will increase, and you will skip elements.
When only the first occurrence has to be removed, the following will also work:
var index = array.indexOf(search_term); // <-- Not supported in <IE9
if (index !== -1) {
array.splice(index, 1);
}
Github did this using the HTML canvas element.
This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.
If you use a browser inspector, you see inside every list element a div with a canvas element.
<div class="participation-graph">
<canvas class="bars" data-color-all="#F5F5F5" data-color-owner="#F5F5F5" data-source="/mxcl/homebrew/graphs/owner_participation" height="80" width="640"></canvas>
</div>
With CSS (z-index, position...) you can put that canvas in the background of a li element or table, in your case.
Do a search about jquery pluggins that fit your requirement.
Hope this pointers help you to achieve that.
The files selected are stored in an array: [input].files
For example, you can access the items
// assuming there is a file input with the ID `my-input`...
var files = document.getElementById("my-input").files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}
For jQuery-comfortable people, it's similarly easy
// assuming there is a file input with the ID `my-input`...
var files = $("#my-input")[0].files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}

Edit: this answer applied to an earlier version of the question that did not mention preserving local changes; the accepted answer from Tim is indeed the correct one. Thanks to qwertzguy for the heads up.
The example 1 will not compile. This version of it compiles and runs. It uses lambda features to abbreviate it.

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.
To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".
To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".
Explanation:
From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):
4.3.8 ‘Local echo’
With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)
Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.
4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.
If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.
Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)
Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.
Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.
The accepted answer is great for single renames, but here is a way to rename multiple images that have the same repository all at once (and remove the old images).
If you have old images of the form:
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
old_name/image_name_1 latest abcdefghijk1 5 minutes ago 1.00GB
old_name/image_name_2 latest abcdefghijk2 5 minutes ago 1.00GB
And you want:
new_name/image_name_1
new_name/image_name_2
Then you can use this (subbing in OLD_REPONAME
, NEW_REPONAME
, and TAG
as appropriate):
OLD_REPONAME='old_name'
NEW_REPONAME='new_name'
TAG='latest'
# extract image name, e.g. "old_name/image_name_1"
for image in $(docker images | awk '{ if( FNR>1 ) { print $1 } }' | grep $OLD_REPONAME)
do \
OLD_NAME="${image}:${TAG}" && \
NEW_NAME="${NEW_REPONAME}${image:${#OLD_REPONAME}:${#image}}:${TAG}" && \
docker image tag $OLD_NAME $NEW_NAME && \
docker rmi $image:${TAG} # omit this line if you want to keep the old image
done
I think this question is about web icons. I've tried giving an icon at 512x512, and on the iPhone 4 simulator it looks great (in the preview) however, when added to the home-screen it's badly pixelated.
On the good side, if you use a larger icon on the iPad (still with my 512x512 test) it does seem to come out in better quality on the iPad. Hopefully the iPhone 4 rendering is a bug.
I've opened a bug about this on radar.
EDIT:
I'm currently using a 114x114 icon in hopes that it'll look good on the iPhone 4 when it is released. If the iPhone 4 still has a bug when it comes out, I'm going to optimize the icon for the iPad (crisp and no resize at 72x72), and then let it scale down for old iPhones.
The css and js files are located within the package: bootstrap/docs/assets/
UPDATE:
since v3 there is a dist
folder in the package that contains all css, js and fonts.
Another option (if you just want to fetch single files) might be: pulldown. Configuration is extremely simple and you can easily add your own files/urls to the list.
Last query print
$queries = \DB::getQueryLog();
$last_query = end($queries);
// Add binding to query
foreach ($last_query['bindings'] as $val) {
$last_query['query'] = preg_replace('/\?/', "'{$val}'", $last_query['query'], 1);
}
dd($last_query);
The modern answer:
if your app support split view on iPad, this problem becomes a little complicated. You need window's size, not the screen's, which may contain 2 apps. Window's size may also vary while running.
Use app's main window's size:
UIApplication.shared.delegate?.window??.bounds.size ?? .zero
Note: The method above may get wrong value before window becoming key window when starting up. if you only need width, method below is very recommended:
UIApplication.shared.statusBarFrame.width
The old solution using UIScreen.main.bounds
will return the device's bounds. If your app running in split view mode, it get the wrong dimensions.
self.view.window
in the hottest answer may get wrong size when app contains 2 or more windows and the window have small size.
Here ngOnChanges will trigger always when your input property changes:
ngOnChanges(changes: SimpleChanges): void {
console.log(changes.categoryId.currentValue)
}
Curl has a built in option for this, called CURLOPT_HEADERFUNCTION. The value of this option must be the name of a callback function. Curl will pass the header (and the header only!) to this callback function, line-by-line (so the function will be called for each header line, starting from the top of the header section). Your callback function then can do anything with it (and must return the number of bytes of the given line). Here is a tested working code:
function HandleHeaderLine( $curl, $header_line ) {
echo "<br>YEAH: ".$header_line; // or do whatever
return strlen($header_line);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.google.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "HandleHeaderLine");
$body = curl_exec($ch);
The above works with everything, different protocols and proxies too, and you dont need to worry about the header size, or set lots of different curl options.
P.S.: To handle the header lines with an object method, do this:
curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(&$object, 'methodName'))
You can create a general (and generic) extension method, like this one:
public static class Extensions
{
public static bool IsDefault<T>(this T value) where T : struct
{
bool isDefault = value.Equals(default(T));
return isDefault;
}
}
Usage:
// We have to set explicit default value '0' to avoid build error:
// Use of unassigned local variable 'intValue'
int intValue = 0;
long longValue = 12;
KeyValuePair<String, int> kvp1 = new KeyValuePair<String, int>("string", 11);
KeyValuePair<String, int> kvp2 = new KeyValuePair<String, int>();
List<KeyValuePair<String, int>> kvps = new List<KeyValuePair<String, int>> { kvp1, kvp2 };
KeyValuePair<String, int> kvp3 = kvps.FirstOrDefault(kvp => kvp.Value == 11);
KeyValuePair<String, int> kvp4 = kvps.FirstOrDefault(kvp => kvp.Value == 15);
Console.WriteLine(intValue.IsDefault()); // results 'True'
Console.WriteLine(longValue.IsDefault()); // results 'False'
Console.WriteLine(kvp1.IsDefault()); // results 'False'
Console.WriteLine(kvp2.IsDefault()); // results 'True'
Console.WriteLine(kvp3.IsDefault()); // results 'False'
Console.WriteLine(kvp4.IsDefault()); // results 'True'
When I am trying to share behavior between 2 closely related classes, I create an abstract class that holds the common behavior and serves as a parent to both classes.
When I am trying to define a Type, a list of methods that a user of my object can reliably call upon, then I create an interface.
For example, I would never create an abstract class with 1 concrete subclass because abstract classes are about sharing behavior. But I might very well create an interface with only one implementation. The user of my code won't know that there is only one implementation. Indeed, in a future release there may be several implementations, all of which are subclasses of some new abstract class that didn't even exist when I created the interface.
That might have seemed a bit too bookish too (though I have never seen it put that way anywhere that I recall). If the interviewer (or the OP) really wanted more of my personal experience on that, I would have been ready with anecdotes of an interface has evolved out of necessity and visa versa.
One more thing. Java 8 now allows you to put default code into an interface, further blurring the line between interfaces and abstract classes. But from what I have seen, that feature is overused even by the makers of the Java core libraries. That feature was added, and rightly so, to make it possible to extend an interface without creating binary incompatibility. But if you are making a brand new Type by defining an interface, then the interface should be JUST an interface. If you want to also provide common code, then by all means make a helper class (abstract or concrete). Don't be cluttering your interface from the start with functionality that you may want to change.
I was looking for the same behavior using jdbi's BindBeanList and found the syntax is exactly the same as Peter Lang's answer above. In case anybody is running into this question, here's my code:
@SqlUpdate("INSERT INTO table_one (col_one, col_two) VALUES <beans> ON DUPLICATE KEY UPDATE col_one=VALUES(col_one), col_two=VALUES(col_two)")
void insertBeans(@BindBeanList(value = "beans", propertyNames = {"colOne", "colTwo"}) List<Beans> beans);
One key detail to note is that the propertyName you specify within @BindBeanList
annotation is not same as the column name you pass into the VALUES()
call on update.
Maybe using pytest_collect_file()
hook you can parse the content of a .txt
o .yaml
file where the tests are specify as you want, and return them to the pytest core.
A nice example is shown in the pytest documentation. I think what you are looking for.

This method applies the standard .gitignore behavior, and does not require manually specifying the files that need to be ignored.
Can't use
--exclude-from=.gitignore
anymore :/ - Here's the updated method:General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!
#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch
git add .gitignore
git commit -m "Create .gitignore"
#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch
git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached
#optionally add anything to the index that was previously ignored but now shouldn't be:
git add *
#commit again
#optionally use the --amend flag to merge this commit with the previous one instead of creating 2 commits.
git commit -m "re-applied modified .gitignore"
#other devs who pull after this commit is pushed will see the newly-.gitignored files DELETED
If you also need to purge the newly-ignored files from the branch's commit history or if you don't want the newly-ignored files to be deleted from future pulls, see this answer.
Patrick Smacchia blogged about this last month, with the following conclusions:
- for loops on List are a bit more than 2 times cheaper than foreach loops on List.
- Looping on array is around 2 times cheaper than looping on List.
- As a consequence, looping on array using for is 5 times cheaper than looping on List using foreach (which I believe, is what we all do).
Rectangle bounds = Screen.GetBounds(Point.Empty);
using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using(Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save("test.jpg", ImageFormat.Jpeg);
}
for capturing current window use
Rectangle bounds = this.Bounds;
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(new Point(bounds.Left,bounds.Top), Point.Empty, bounds.Size);
}
bitmap.Save("C://test.jpg", ImageFormat.Jpeg);
}
I just wanted to add onto eskis' fantastic answer for people having trouble. (Note: This will only work and look like separate directories inside the 'project' view, not the 'android' view unfortunately.)
Tested with the following. BuildToolsVersion = 23.0.0 gradle 1.2.3 & 1.3.0
This is how I got mine to work with an already built project.
Once this is complete, go into your modules gradle.build file and create a sourceSets definition like this...(Make sure 'src/main/res/layouts' & 'src/main/res' are always the bottom two!!!! Like I am showing below).
sourceSets {
main {
res.srcDirs =
[
'src/main/res/layouts/activities',
'src/main/res/layouts/fragments',
'src/main/res/layouts/content',
'src/main/res/layouts',
'src/main/res'
]
}
}
Profit $$$$
But seriously.. this is how I got it to work. Let me know if anyone has any questions.. I can try to help.
Pictures are worth more than words.
I had a dynamically generated, but badly formed table with a typo. I copied a <td>
tag inside another <td>
by mistake. My column count matched. I had <thead>
and <tbody>
tags. Everything matched, except for this little mistake I didn't notice for a while, because my column had a lot of link and image tags in it.
There are two ways to use this variable:
passing it as a command line argument just like Job mentioned:
cmake -DCMAKE_INSTALL_PREFIX=< install_path > ..
assigning value to it in CMakeLists.txt
:
SET(CMAKE_INSTALL_PREFIX < install_path >)
But do remember to place it BEFORE PROJECT(< project_name>)
command, otherwise it will not work!
You can adjust the plot margins with plot.margin
in theme()
and then move your axis labels and title with the vjust
argument of element_text()
. For example :
library(ggplot2)
library(grid)
qplot(rnorm(100)) +
ggtitle("Title") +
theme(axis.title.x=element_text(vjust=-2)) +
theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
theme(plot.title=element_text(size=15, vjust=3)) +
theme(plot.margin = unit(c(1,1,1,1), "cm"))
will give you something like this :
If you want more informations about the different theme()
parameters and their arguments, you can just enter ?theme
at the R prompt.
I wouldn't even pay attention to the contents of the parens.
Just match any line that starts with for
and ends with semi-colon:
^\t*for.+;$
Unless you've got for
statements split over multiple lines, that will work fine?
The minimum ranges you can rely on are:
short int
and int
: -32,767 to 32,767unsigned short int
and unsigned int
: 0 to 65,535long int
: -2,147,483,647 to 2,147,483,647unsigned long int
: 0 to 4,294,967,295This means that no, long int
cannot be relied upon to store any 10 digit number. However, a larger type long long int
was introduced to C in C99 and C++ in C++11 (this type is also often supported as an extension by compilers built for older standards that did not include it). The minimum range for this type, if your compiler supports it, is:
long long int
: -9,223,372,036,854,775,807 to 9,223,372,036,854,775,807unsigned long long int
: 0 to 18,446,744,073,709,551,615So that type will be big enough (again, if you have it available).
A note for those who believe I've made a mistake with these lower bounds - I haven't. The C requirements for the ranges are written to allow for ones' complement or sign-magnitude integer representations, where the lowest representable value and the highest representable value differ only in sign. It is also allowed to have a two's complement representation where the value with sign bit 1 and all value bits 0 is a trap representation rather than a legal value. In other words, int
is not required to be able to represent the value -32,768.
You can set the default for related field in your model class (in mapping definition or set the value yourself).
Furthermore, FormBuilder gives you a chance to set initial values with setData() method. Form builder is passed to the createForm() method of your form class.
Also, check this link: http://symfony.com/doc/current/book/forms.html#using-a-form-without-a-class
If you are running a script, instead of a statement, you can increase this by selecting Tools/Preferences/Worksheet and increasing "Max Rows to print in a script". The default is 5000, you can change it to any size.
To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.
Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.
Use CTRL+D
at each line and it will find the matching words and select them then you can use multiple cursors.
You can also use find to find all the occurrences and then it would be multiple cursors too.
Using test
if test ! -z "$(docker images -q <name:tag>)"; then
echo "Exist"
fi
or in one line
test ! -z "$(docker images -q <name:tag>)" && echo exist
to Print JSON parsed object just type
console.log( JSON.stringify(data, null, " ") );
and you will get output very clear
@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.
import numpy as np
import matplotlib.pyplot as plt
# make some data
x = np.linspace(0, 2*np.pi)
y1 = np.sin(x)
y2 = np.cos(x)
# plot sin(x) and cos(x)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')
leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
text.set_fontsize('x-large')
plt.savefig('leg_example')
plt.show()
import numpy as np
import matplotlib.pyplot as plt
# make some data
x = np.linspace(0, 2*np.pi)
y1 = np.sin(x)
y2 = np.cos(x)
# plot sin(x) and cos(x)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')
leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()
The above two methods produce the same output image:
^(\(?[0-9]{3}\)?)((\s|\-){1})?[0-9]{3}((\s|\-){1})?[0-9]{4}$
Assuming you are validating US phone numbers, this will do the trick.
First, we allow 0 or 1 open parentheses to start \(?
Then, we allow 3 consecutive digits between 0-9 [0-9]{3}
After, we repeat the first step and allow 0 or 1 closing parentheses \)?
For the second grouping, we start by allowing a space or a hyphen 0 or 1 times ((\s|\-){1})?
This is repeated between the second and third grouping of numbers, and we check for 3 consecutive digits then four consecutive digits to end it. For US phone numbers I think this covers the bases for a lot of different ways that people might format the number, but is restrictive enough that they can't pass an unreasonable string.
Answering old thread here (and a bit off-topic) because it's what I found when I was searching how to install Image Magick on Mac OS to run on the local webserver. It's not enough to brew install Imagemagick. You have to also PECL install it so the PHP module is loaded.
From this SO answer:
brew install php
brew install imagemagick
brew install pkg-config
pecl install imagick
And you may need to sudo apachectl restart
. Then check your phpinfo()
within a simple php script running on your web server.
If it's still not there, you probably have an issue with running multiple versions of PHP on the same Mac (one through the command line, one through your web server). It's beyond the scope of this answer to resolve that issue, but there are some good options out there.
for word in d:
if d in paid[j]:
do_something()
will try all the words in the list d
and check if they can be found in the string paid[j]
.
This is not very efficient since paid[j]
has to be scanned again for each word in d
. You could also use two sets, one composed of the words in the sentence, one of your list, and then look at the intersection of the sets.
sentence = "words don't come easy"
d = ["come", "together", "easy", "does", "it"]
s1 = set(sentence.split())
s2 = set(d)
print (s1.intersection(s2))
Output:
{'come', 'easy'}
Your comparison function between old value and new value is having some issue. It is better not to complicate things so much, as it will increase your debugging effort later. You should keep it simple.
The best way is to create a person-component
and watch every person separately inside its own component, as shown below:
<person-component :person="person" v-for="person in people"></person-component>
Please find below a working example for watching inside person component. If you want to handle it on parent side, you may use $emit
to send an event upwards, containing the id
of modified person.
Vue.component('person-component', {_x000D_
props: ["person"],_x000D_
template: `_x000D_
<div class="person">_x000D_
{{person.name}}_x000D_
<input type='text' v-model='person.age'/>_x000D_
</div>`,_x000D_
watch: {_x000D_
person: {_x000D_
handler: function(newValue) {_x000D_
console.log("Person with ID:" + newValue.id + " modified")_x000D_
console.log("New age: " + newValue.age)_x000D_
},_x000D_

This works
It will create a Executor with a single thread, that can get a lot of tasks; and will wait for the current one to end execution to begin with the next
In case of uncaugth error or exception the uncaughtExceptionHandler will catch it
public final class SingleThreadExecutorWithExceptions { public static ExecutorService newSingleThreadExecutorWithExceptions(final Thread.UncaughtExceptionHandler uncaughtExceptionHandler) { ThreadFactory factory = (Runnable runnable) -> { final Thread newThread = new Thread(runnable, "SingleThreadExecutorWithExceptions"); newThread.setUncaughtExceptionHandler( (final Thread caugthThread,final Throwable throwable) -> { uncaughtExceptionHandler.uncaughtException(caugthThread, throwable); }); return newThread; }; return new FinalizableDelegatedExecutorService (new ThreadPoolExecutor(1, 1, 0L, TimeUnit.MILLISECONDS, new LinkedBlockingQueue(), factory){ protected void afterExecute(Runnable runnable, Throwable throwable) { super.afterExecute(runnable, throwable); if (throwable == null && runnable instanceof Future) { try { Future future = (Future) runnable; if (future.isDone()) { future.get(); } } catch (CancellationException ce) { throwable = ce; } catch (ExecutionException ee) { throwable = ee.getCause(); } catch (InterruptedException ie) { Thread.currentThread().interrupt(); // ignore/reset } } if (throwable != null) { uncaughtExceptionHandler.uncaughtException(Thread.currentThread(),throwable); } } }); } private static class FinalizableDelegatedExecutorService extends DelegatedExecutorService { FinalizableDelegatedExecutorService(ExecutorService executor) { super(executor); } protected void finalize() { super.shutdown(); } } /** * A wrapper class that exposes only the ExecutorService methods * of an ExecutorService implementation. */ private static class DelegatedExecutorService extends AbstractExecutorService { private final ExecutorService e; DelegatedExecutorService(ExecutorService executor) { e = executor; } public void execute(Runnable command) { e.execute(command); } public void shutdown() { e.shutdown(); } public List shutdownNow() { return e.shutdownNow(); } public boolean isShutdown() { return e.isShutdown(); } public boolean isTerminated() { return e.isTerminated(); } public boolean awaitTermination(long timeout, TimeUnit unit) throws InterruptedException { return e.awaitTermination(timeout, unit); } public Future submit(Runnable task) { return e.submit(task); } public Future submit(Callable task) { return e.submit(task); } public Future submit(Runnable task, T result) { return e.submit(task, result); } public List> invokeAll(Collection> tasks) throws InterruptedException { return e.invokeAll(tasks); } public List> invokeAll(Collection> tasks, long timeout, TimeUnit unit) throws InterruptedException { return e.invokeAll(tasks, timeout, unit); } public T invokeAny(Collection> tasks) throws InterruptedException, ExecutionException { return e.invokeAny(tasks); } public T invokeAny(Collection> tasks, long timeout, TimeUnit unit) throws InterruptedException, ExecutionException, TimeoutException { return e.invokeAny(tasks, timeout, unit); } } private SingleThreadExecutorWithExceptions() {} }
This should answer that question, and then some.
The second line, if (obj.GetType() == typeof(ClassA)) {}
, is faster, for those that don't want to read the article.

Creating and using the key is the way to go. The usage is free until your application reaches 25.000 calls per day on 90 consecutive days.
BTW.: In the google Developer documentation it says you shall add the api key as option {key:yourKey} when calling the API to create new instances. This however doesn't shush the console warning. You have to add the key as a parameter when including the api.
<script src="https://maps.googleapis.com/maps/api/js?key=yourKEYhere"></script>
Get the key here: GoogleApiKey Generation site
As long as you are assigning a single variable, you can also use plain assignment in a plpgsql function:
name := (SELECT t.name from test_table t where t.id = x);
Or use SELECT INTO
like @mu already provided.
This works, too:
name := t.name from test_table t where t.id = x;
But better use one of the first two, clearer methods, as @Pavel commented.
I shortened the syntax with a table alias additionally.
Update: I removed my code example and suggest to use IF EXISTS()
instead like provided by @Pavel.
First I installed the Nvidia driver.
Next I installed cuda.
Ater that I got the "Driver/library version mismatch" ERROR but I could see the cuda version so I purged the Nvidia driver and reinstall it.
Then it worked correctly.
If you can get i["MyPhone"]
as a long
, you can use the long.ToString()
method to format it:
Convert.ToLong(i["MyPhone"]).ToString("###-###-####");
See the MSDN page on Numeric Format Strings.
Be careful to use long rather than int: int could overflow.
Because the numbers after point is only zero, the best solution is to use the Math.Round(MyNumber)
Bash supports all sorts of wildcards and expansions.
Your exact case would be handled by brace expansion, like so:
$ rm -rf abc.log.2012-03-{14,27,28}
The above would expand to a single command with all three arguments, and be equivalent to typing:
$ rm -rf abc.log.2012-03-14 abc.log.2012-03-27 abc.log.2012-03-28
It's important to note that this expansion is done by the shell, before rm
is even loaded.
You can skip the Performance counter check in the setup altogether:
setup.exe /ACTION=install /SKIPRULES=PerfMonCounterNotCorruptedCheck
You don't see any compression happening for your String, As you atleast require couple of hundred bytes to have real compression using GZIPOutputStream or ZIPOutputStream. Your String is too small.(I don't understand why you require compression for same)
Check Conclusion from this article:
The article also shows how to compress and decompress data on the fly in order to reduce network traffic and improve the performance of your client/server applications. Compressing data on the fly, however, improves the performance of client/server applications only when the objects being compressed are more than a couple of hundred bytes. You would not be able to observe improvement in performance if the objects being compressed and transferred are simple String objects, for example.
I'd do something like this:
function renameKeys(dict, keyMap) {
return _.reduce(dict, function(newDict, val, oldKey) {
var newKey = keyMap[oldKey] || oldKey
newDict[newKey] = val
return newDict
}, {})
}
To clean this up a little bit and maintain a single line of code (like you would with a toggle()
), you can use a ternary operator so your code winds up looking like this (also using jQuery):
$('#video-over').css('visibility', $('#video-over').css('visibility') == 'hidden' ? 'visible' : 'hidden');
Yes. This error is a structured exception that wasn't mapped into a .NET error. It's probably your DataGrid mapping throwing a native exception that was uncaught.
You can tell what exception is occurring by looking at the ExternalException.ErrorCode property. I'd check your stack trace, and if it's tied to the DevExpress grid, report the problem to them.
Two things you can check is,
class Slider extends React.Component {
// Your React Code
}
Slider.propTypes = {
// accessibility: PropTypes.bool,
}
This example made everything clear for me:
As you can see setSoTimeout prevent the program to hang! It wait for SO_TIMEOUT
time! if it does not get any signal it throw exception! It means that time expired!
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketTimeoutException;
public class SocketTest extends Thread {
private ServerSocket serverSocket;
public SocketTest() throws IOException {
serverSocket = new ServerSocket(8008);
serverSocket.setSoTimeout(10000);
}
public void run() {
while (true) {
try {
System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "...");
Socket client = serverSocket.accept();
System.out.println("Just connected to " + client.getRemoteSocketAddress());
client.close();
} catch (SocketTimeoutException s) {
System.out.println("Socket timed out!");
break;
} catch (IOException e) {
e.printStackTrace();
break;
}
}
}
public static void main(String[] args) {
try {
Thread t = new SocketTest();
t.start();
} catch (IOException e) {
e.printStackTrace();
}
}

I looked around the internet for correct dimensions for these densities for square images, but couldn't find anything reliable.

The $.grep()
method eliminates items from an array as necessary so that only remaining items carry a given search. The test is a function that is passed an array item and the index of the item within the array. Only if the test returns true will the item be in the result array.
