This worked for me

In JSP, to view the image

<img src="${pageContext.request.contextPath}/resources/images/slide-are.jpg">

In dispatcher-servlet.xml

<mvc:annotation-driven />
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources/" />

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

1. Add the icon to the project resources and rename to icon.

2. Open the designer of the form you want to add the icon to.

3. Append the InitializeComponent function.

4. Add this line in the top:

   this.Icon = PROJECTNAME.Properties.Resources.icon;
   

   repeat step 4 for any forms in your project you want to update

If you are using spring, then you can use the the following method to read file from src/main/resources:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.springframework.core.io.ClassPathResource;

  public String readFileToString(String path) throws IOException {

    StringBuilder resultBuilder = new StringBuilder("");
    ClassPathResource resource = new ClassPathResource(path);

    try (
        InputStream inputStream = resource.getInputStream();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream))) {

      String line;

      while ((line = bufferedReader.readLine()) != null) {
        resultBuilder.append(line);
      }

    }

    return resultBuilder.toString();
  }

You can try this also:

private void Page_Loaded_1(object sender, RoutedEventArgs e)
    {
        Uri iconUri = new Uri(@"C:\Apps\R&D\WPFNavigation\WPFNavigation\Images\airport.ico", UriKind.RelativeOrAbsolute);
        (this.Parent as Window).Icon = BitmapFrame.Create(iconUri);
    }

If the backend of the REST API is a SQL relational database, then

1. you should have RowVersion in every record that can be updated (to avoid the lost update problem)
2. you should always return a new copy of the record after PUT (to get the new RowVersion).

If you don't care about lost updates, or if you want to force your clients to do a GET immediately after a PUT, then don't return anything from PUT.

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

I had the same issue, but in my case i places a class in a usercontrol which is related to the usercontrol like this

Public Class MyUserControlObject

end Class

Public Class MyUserCOntrol

end Class

The solution was to move the MyUserControlObject to the end of the Usercontrol class, like this

Public Class MyUserCOntrol

end Class

Public Class MyUserControlObject

end Class

I hope this helps

Locale locale = new Locale("en");
Locale.setDefault(locale);

Configuration config = context.getResources().getConfiguration();
config.setLocale(locale);
context.createConfigurationContext(config);

Important update:

context.getResources().updateConfiguration(config, context.getResources().getDisplayMetrics());

Note, that on SDK >= 21, you need to call 'Resources.updateConfiguration()', otherwise resources will not be updated.

If you loaded the resource using the visual studio UI, then you should be able to do this:

picturebox.Image = project.Properties.Resources.imgfromresource

This isn’t a solution in the sense that it doesn’t resolve the conditions which cause the message to appear in the logs, but the message can be suppressed by appending the following to conf/logging.properties:

org.apache.catalina.webresources.Cache.level = SEVERE

This filters out the “Unable to add the resource” logs, which are at level WARNING.

In my view a WARNING is not necessarily an error that needs to be addressed, but rather can be ignored if desired.

This link tells you how.

The magic is the getResourceAsStream() method :

InputStream is = 
this.getClass().getClassLoader().getResourceAsStream("yourpackage/mypackage/myfile.xml")

If aim is to create a resources folder parallel to src/main/java, then do the following:

Right Click on your project > New > Source Folder
Provide Folder Name as src/main/resources
Finish

Really good book. Has a high-level taste of the most important areas of computer science. Yes, CS != programming, but this is still useful to every programmer.

Found all answers useful, just wanted to add one more use case.

In a composite WPF scenario, your user control can make use of resources defined in any other parent window/control (that is going to host this user control) by referring to that resource as DynamicResource.

As mentioned by others, Staticresource will be looked up at compile time. User controls can not refer to those resources which are defined in hosting/parent control. Though, DynamicResource could be used in this case.

In Embedded Jetty I managed to achieve something similar by adding a mapping for the "css" directory in web.xml. Explicitly telling it to use DefaultServlet:

<servlet>
  <servlet-name>DefaultServlet</servlet-name>
  <servlet-class>org.eclipse.jetty.servlet.DefaultServlet</servlet-class>
</servlet>

<servlet-mapping>
  <servlet-name>DefaultServlet</servlet-name>
  <url-pattern>/css/*</url-pattern>
</servlet-mapping>

Because java.net.URL is not adequate for handling all kinds of low level resources, Spring introduced org.springframework.core.io.Resource. To access resources, we can use @Value annotation or ResourceLoader class. @Autowired private ResourceLoader resourceLoader;

@Override public void run(String... args) throws Exception {

    Resource res = resourceLoader.getResource("classpath:thermopylae.txt");

    Map<String, Integer> words =  countWords.getWordsCount(res);

    for (String key : words.keySet()) {

        System.out.println(key + ": " + words.get(key));
    }
}

You can just put it in on the file system. Eclipse will pick up the change on the next refresh. Click the folder and press F5 to refresh. BTW, make sure the file name does not have any capital letters... it will break android... and eclipse will let you know.

I got the resources on C# (Desktop WPF W/ .NET Framework 4.8) using the code below

{DefaultNamespace}.Properties.Resources.{ResourceName}

While searching this very question I discovered this example in the documentation.

QPushButton *quitButton = new QPushButton("Quit");
connect(quitButton, &QPushButton::clicked, &app, &QCoreApplication::quit, Qt::QueuedConnection);

Mutatis mutandis for your particular action of course.

Along with this note.

It's good practice to always connect signals to this slot using a QueuedConnection. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop.

It's common to connect the QGuiApplication::lastWindowClosed() signal to quit()

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

• JSF resource versioning
• JSF2 Static resource caching

This will get you a string array of all the resources:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();

Here are two approaches you can read raw resources using Kotlin.

You can get it by getting the resource id. Or, you can use string identifier in which you can programmatically change the filename with incrementation.

Cheers mate

// R.raw.data_post

this.context.resources.openRawResource(R.raw.data_post)
this.context.resources.getIdentifier("data_post", "raw", this.context.packageName)

In addition to Cristian C's answer (sorry, I do not have the ability to make comments), if you make one handler for both buttons, you may directly compare v to b1 and b2, or if you want to compare by the ID, you do not need to cast v to Button (View has getId() method, too), and that way there is no worry of cast exception.

The Spring Framework has a class which allows to recursively search through the classpath:

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
resolver.getResources("classpath*:some/package/name/**/*.xml");

The above method works good.

Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.

To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).

To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name]).

Using Reflections

Get everything on the classpath:

Reflections reflections = new Reflections(null, new ResourcesScanner());
Set<String> resourceList = reflections.getResources(x -> true);

Another example - get all files with extension .csv from some.package:

Reflections reflections = new Reflections("some.package", new ResourcesScanner());
Set<String> fileNames = reflections.getResources(Pattern.compile(".*\\.csv"));

Here is a simple method to read the text file from the raw folder:

public static String readTextFile(Context context,@RawRes int id){
    InputStream inputStream = context.getResources().openRawResource(id);
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

    byte buffer[] = new byte[1024];
    int size;
    try {
        while ((size = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, size);
        }
        outputStream.close();
        inputStream.close();
    } catch (IOException e) {

    }
    return outputStream.toString();
}

In the hopes of providing additional information for those who don't pick this up as quickly as others, I'd like to provide my scenario as it has a slightly different setup. My project was setup with the following directory structure (using Eclipse):

Project/
  src/                // application source code
    org/
      myproject/
        MyClass.java
  test/               // unit tests
  res/                // resources
    images/           // PNG images for icons
      my-image.png
    xml/              // XSD files for validating XML files with JAXB
      my-schema.xsd
    conf/             // default .conf file for Log4j
      log4j.conf
  lib/                // libraries added to build-path via project settings

I was having issues loading my resources from the res directory. I wanted all my resources separate from my source code (simply for managment/organization purposes). So, what I had to do was add the res directory to the build-path and then access the resource via:

static final ClassLoader loader = MyClass.class.getClassLoader();

// in some function
loader.getResource("images/my-image.png");
loader.getResource("xml/my-schema.xsd");
loader.getResource("conf/log4j.conf");

NOTE: The / is omitted from the beginning of the resource string because I am using ClassLoader.getResource(String) instead of Class.getResource(String).

The java.lang.management package does give you a whole lot more info than Runtime - for example it will give you heap memory (ManagementFactory.getMemoryMXBean().getHeapMemoryUsage()) separate from non-heap memory (ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage()).

You can also get process CPU usage (without writing your own JNI code), but you need to cast the java.lang.management.OperatingSystemMXBean to a com.sun.management.OperatingSystemMXBean. This works on Windows and Linux, I haven't tested it elsewhere.

For example ... call the get getCpuUsage() method more frequently to get more accurate readings.

public class PerformanceMonitor { 
    private int  availableProcessors = getOperatingSystemMXBean().getAvailableProcessors();
    private long lastSystemTime      = 0;
    private long lastProcessCpuTime  = 0;

    public synchronized double getCpuUsage()
    {
        if ( lastSystemTime == 0 )
        {
            baselineCounters();
            return;
        }

        long systemTime     = System.nanoTime();
        long processCpuTime = 0;

        if ( getOperatingSystemMXBean() instanceof OperatingSystemMXBean )
        {
            processCpuTime = ( (OperatingSystemMXBean) getOperatingSystemMXBean() ).getProcessCpuTime();
        }

        double cpuUsage = (double) ( processCpuTime - lastProcessCpuTime ) / ( systemTime - lastSystemTime );

        lastSystemTime     = systemTime;
        lastProcessCpuTime = processCpuTime;

        return cpuUsage / availableProcessors;
    }

    private void baselineCounters()
    {
        lastSystemTime = System.nanoTime();

        if ( getOperatingSystemMXBean() instanceof OperatingSystemMXBean )
        {
            lastProcessCpuTime = ( (OperatingSystemMXBean) getOperatingSystemMXBean() ).getProcessCpuTime();
        }
    }
}

File relativeFile = new File(getClass().getResource("/icons/forIcon.png").toURI());
myJFrame.setIconImage(tk.getImage(relativeFile.getAbsolutePath()));

As of API 21, you could also use:

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

If you use MVC 3 and .NET 4, you can use the new Display attribute in the System.ComponentModel.DataAnnotations namespace. This attribute replaces the DisplayName attribute and provides much more functionality, including localization support.

In your case, you would use it like this:

public class MyModel
{
    [Required]
    [Display(Name = "labelForName", ResourceType = typeof(Resources.Resources))]
    public string name{ get; set; }
}

As a side note, this attribute will not work with resources inside App_GlobalResources or App_LocalResources. This has to do with the custom tool (GlobalResourceProxyGenerator) these resources use. Instead make sure your resource file is set to 'Embedded resource' and use the 'ResXFileCodeGenerator' custom tool.

(As a further side note, you shouldn't be using App_GlobalResources or App_LocalResources with MVC. You can read more about why this is the case here)

Just use <c:url>-tag with an application context relative path.

When the value parameter starts with an /, then the tag will treat it as an application relative url, and will add the application-name to the url. Example:

jsp:

<c:url value="/templates/style/main.css" var="mainCssUrl" />`
<link rel="stylesheet" href="${mainCssUrl}" />
...
<c:url value="/home" var="homeUrl" />`
<a href="${homeUrl}">home link</a>

will become this html, with an domain relative url:

<link rel="stylesheet" href="/AppName/templates/style/main.css" />
...
<a href="/AppName/home">home link</a>

ResourceManager will work if your image is in a resource file. If it is just a file in your project (let's say the root) you can get it using something like this:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.IO.Stream file = assembly .GetManifestResourceStream("AssemblyName." + channel);
this.pictureBox1.Image = Image.FromStream(file);

Or if you're in WPF:

    private ImageSource GetImage(string channel)
    {
        StreamResourceInfo sri = Application.GetResourceStream(new Uri("/TestApp;component/" + channel, UriKind.Relative));
        BitmapImage bmp = new BitmapImage();
        bmp.BeginInit();
        bmp.StreamSource = sri.Stream;
        bmp.EndInit();

        return bmp;
    }

You may have to restart android studio if above solutions aren't working, i restarted it and then it works.

We can also use it for the guideline of the constraint layout.

Create integer.xml file and add into

 <item name="guideline_button_top" type="integer" format="float">0.60</item>

Use from a layout.xml file

 app:layout_constraintGuide_percent="@integer/guideline_button_top" 

To safe, you should add: mContext.getResources().getString(R.string.your_string);

mContext can be: context in onAttach() of Fragment or this of Activity.

For raw files, you should consider creating a raw folder inside res directory and then call getResources().openRawResource(resourceName) from your activity.

I know it really late for another answer but I just wanted to share what helped me at the end. It will also load resources/files from the absolute path of the file system (not only the classpath's).

public class ResourceLoader {

    public static URL getResource(String resource) {
        final List<ClassLoader> classLoaders = new ArrayList<ClassLoader>();
        classLoaders.add(Thread.currentThread().getContextClassLoader());
        classLoaders.add(ResourceLoader.class.getClassLoader());

        for (ClassLoader classLoader : classLoaders) {
            final URL url = getResourceWith(classLoader, resource);
            if (url != null) {
                return url;
            }
        }

        final URL systemResource = ClassLoader.getSystemResource(resource);
        if (systemResource != null) {
            return systemResource;
        } else {
            try {
                return new File(resource).toURI().toURL();
            } catch (MalformedURLException e) {
                return null;
            }
        }
    }

    private static URL getResourceWith(ClassLoader classLoader, String resource) {
        if (classLoader != null) {
            return classLoader.getResource(resource);
        }
        return null;
    }

}

@Emracool... I'd suggest you an alternative. Since you seem to be trying to load a *.txt file. Better to use FileInputStream() rather then this annoying getClass().getClassLoader().getResourceAsStream() or getClass().getResourceAsStream(). At least your code will execute properly.

For me it happened because I tried to mix xml vector graphics images with ordinary png in the same layout file,

only after I replaced the xml vector graphics with pngs it started to work

In my case, I have used a URL object instead Path.

File

File file = new File("my_path");
URL url = file.toURI().toURL();

Resource in classpath using classloader

URL url = MyClass.class.getClassLoader().getResource("resource_name")

When I need to read the content, I can use the following code:

InputStream stream = url.openStream();

And you can access the content using an InputStream.

Create the classLoader instance of the class you need, then you can access the files or resources easily. now you access path using getPath() method of that class.

 ClassLoader classLoader = getClass().getClassLoader();
 String path  = classLoader.getResource("chromedriver.exe").getPath();
 System.out.println(path);

Here is a bit of code from one of my applications... Let me know if it suits your needs. You can use this if you know the file you want to use.

URL defaultImage = ClassA.class.getResource("/packageA/subPackage/image-name.png");
File imageFile = new File(defaultImage.toURI());

Hope that helps.

It just needs to be in the classpath (aka make sure it ends up under /WEB-INF/classes in the .war as part of the build).

Plural

• Simple - all urls start with the same prefix
• Logical - orders/ gets an index list of orders.
• Standard - Most widely adopted standard followed by the overwhelming majority of public and private APIs.

For example:

GET /resources - returns a list of resource items

POST /resources - creates one or many resource items

PUT /resources - updates one or many resource items

PATCH /resources - partially updates one or many resource items

DELETE /resources - deletes all resource items

And for single resource items:

GET /resources/:id - returns a specific resource item based on :id parameter

POST /resources/:id - creates one resource item with specified id (requires validation)

PUT /resources/:id - updates a specific resource item

PATCH /resources/:id - partially updates a specific resource item

DELETE /resources/:id - deletes a specific resource item

To the advocates of singular, think of it this way: Would you ask a someone for an order and expect one thing, or a list of things? So why would you expect a service to return a list of things when you type /order?

The Scanner should be closed. It is a good practice to close Readers, Streams...and this kind of objects to free up resources and aovid memory leaks; and doing so in a finally block to make sure that they are closed up even if an exception occurs while handling those objects.

I have a project in which I have the following TextView :

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textStyle="bold"
    android:text="@string/app_name"
    android:layout_gravity="center" 
/>

So, I'm guessing you need to use android:textStyle

Yes, Guava provides this in the Resources class. For example:

URL url = Resources.getResource("foo.txt");
String text = Resources.toString(url, StandardCharsets.UTF_8);

You don't say if this is a desktop or web app. I would use the getResourceAsStream() method from an appropriate ClassLoader if it's a desktop or the Context if it's a web app.

Try moving your layout xml from res/layout-land to res/layout folder

How to get an application resource id from the resource name is quite a common and well answered question.

How to get a native Android resource id from the resource name is less well answered. Here's my solution to get an Android drawable resource by resource name:

public static Drawable getAndroidDrawable(String pDrawableName){
    int resourceId=Resources.getSystem().getIdentifier(pDrawableName, "drawable", "android");
    if(resourceId==0){
        return null;
    } else {
        return Resources.getSystem().getDrawable(resourceId);
    }
}

The method can be modified to access other types of resources.

If you still have problems with Eclipse finding your files, you might try the following:

1. Verify that the file exists according to the current execution environment by using the java.io.File class to get a canonical path format and verify that (a) the file exists and (b) what the canonical path is.

2. Verify the default working directory by printing the following in your main:

       System.out.println("Working dir:  " + System.getProperty("user.dir"));
   

For (1) above, I put the following debugging code around the specific file I was trying to access:

            File imageFile = new File(source);
            System.out.println("Canonical path of target image: " + imageFile.getCanonicalPath());
            if (!imageFile.exists()) {
                System.out.println("file " + imageFile + " does not exist");
            }
            image = ImageIO.read(imageFile);                

For whatever reason, I ended up ignoring most of the other posts telling me to put the image files in "src" or some other variant, as I verified that the system was looking at the root of the Eclipse project directory hierarchy (e.g., $HOME/workspace/myProject).

Having the images in src/ (which is automatically copied to bin/) didn't do the trick on Eclipse Luna.

Thanks, Valter Henrique, with your tip i managed to realise, that i simply entered incorrect path to this image. In one of my tries i use

    String pathToImageSortBy = "resources/testDataIcons/filling.png";
    ImageIcon SortByIcon = new ImageIcon(getClass().getClassLoader().getResource(pathToImageSortBy));

But correct way was use name of my project in path to resource

String pathToImageSortBy = "nameOfProject/resources/testDataIcons/filling.png";
ImageIcon SortByIcon = new ImageIcon(getClass().getClassLoader().getResource(pathToImageSortBy));

if you are calling from static method, use :

TestGameTable.class.getClassLoader().getResource("dice.jpg");

Actually it happens when the number of processes exceeds the limits set by the hosting provider.

To avoid either we need to enhance the capacity by hosting providers or we need to check in the code whether any process takes longer time (like background tasks).

One more way to use timeit:

from timeit import timeit

def func():
    return 1 + 1

time = timeit(func, number=1)
print(time)

Let me also give you the SON of JSON version:

import nl.typeset.sonofjson._

arr(
  obj(id = 1, name = "John)
  obj(id = 2, name = "Dani)
)

For the last enterprise application I worked on that needed to handle a notable amount of CSV -- a couple of months ago -- I used SuperCSV at sourceforge and found it simple, robust and problem-free.

if you run the command "forever logs", you can see where are the logs files.

Hope that helps

I have a lot of issues with most of the answers posted - they either use deprecated libraries that have been ported over with limited features, or provide a solution with too much magic on the execution of the request, making it difficult to error handle. If they do not fall into one of the above categories, they're 3rd party libraries or deprecated.

Some of the solutions works alright purely in http requests, but the solutions fall short for any other kind of request, which is ludicrous. A highly customized solution is not necessary here.

Simply using the python built-in library asyncio is sufficient enough to perform asynchronous requests of any type, as well as providing enough fluidity for complex and usecase specific error handling.

import asyncio

loop = asyncio.get_event_loop()

def do_thing(params):
    async def get_rpc_info_and_do_chores(id):
        # do things
        response = perform_grpc_call(id)
        do_chores(response)

    async def get_httpapi_info_and_do_chores(id):
        # do things
        response = requests.get(URL)
        do_chores(response)

    async_tasks = []
    for element in list(params.list_of_things):
       async_tasks.append(loop.create_task(get_chan_info_and_do_chores(id)))
       async_tasks.append(loop.create_task(get_httpapi_info_and_do_chores(ch_id)))

    loop.run_until_complete(asyncio.gather(*async_tasks))

How it works is simple. You're creating a series of tasks you'd like to occur asynchronously, and then asking a loop to execute those tasks and exit upon completion. No extra libraries subject to lack of maintenance, no lack of functionality required.

Not sure if your teacher allows you to use filters but...

filter(lambda x: x.isalpha(), "a1a2a3s3d4f5fg6h")

returns-

'aaasdffgh'

Much more efficient than looping...

Example:

for i in range(10):
  a.replace(str(i),'')

Use a regular expression validator instead. This will work on the client side using JavaScript, but also when JavaScript is disabled (as the length check will be performed on the server as well).

The following example checks that the entered value is between 0 and 100 characters long:

<asp:RegularExpressionValidator runat="server" ID="valInput"
    ControlToValidate="txtInput"
    ValidationExpression="^[\s\S]{0,100}$"
    ErrorMessage="Please enter a maximum of 100 characters"
    Display="Dynamic">*</asp:RegularExpressionValidator>

There are of course more complex regexs you can use to better suit your purposes.

>>> print sorted(d.keys())
['a', 'b', 'c']

Use the sorted function, which sorts the iterable passed in.

The .keys() method returns the keys in an arbitrary order.

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

I suggest you to use Message Properte from The Exception Object Like below code

try
{
 object result = processClass.InvokeMethod("Create", methodArgs);
}
catch (Exception e)
{  
    //use Console.Write(e.Message); from Console Application 
    //and use MessageBox.Show(e.Message); from WindowsForm and WPF Application
}

The datatype in the same columns name must be equals.

dataTable1.Merge(dataTable2);

After that the result is:

dataTable1 = dataTable1 + dataTable2

            mask.path = path.cgPath
            layer.mask = mask

    }

I was stuck on this same issue for what felt like an eternity.

My problem was: I was running mysql from MAMP on port 8889, but when trying to connect to mysql from my command line, it was expecting port 3306. I was running out of ideas, so I tried:

mysql --port 8889

and happiness ensued:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

It describes a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.It contains the following properties.

The String class exposes some methods to enable this, such as IndexOf and LastIndexOf, so that you may do this:

Dim myText = "abcde"
Dim dIndex = myText.IndexOf("d")
If (dIndex > -1) Then

End If

A branch is just a reference to a commit. Until you commit anything to the repository, you don't have any branches. You can see this in a non-bare repository as well.

$ mkdir repo
$ cd repo
$ git init
Initialized empty Git repository in /home/me/repo/.git/
$ git branch
$ touch foo
$ git add foo
$ git commit -m "new file"
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 foo
$ git branch
* master

I had trouble getting this to work and added another solution for anyone wanting/ needing to use FromCollection.

Instead of:

@Html.CheckBoxFor(model => true, item.TemplateId) 

Format html helper like so:

@Html.CheckBoxFor(model => model.SomeProperty, new { @class = "form-control", Name = "SomeProperty"})

Then in the viewmodel/model wherever your logic is:

public void Save(FormCollection frm)
{   
    // to do instantiate object.

    instantiatedItem.SomeProperty = (frm["SomeProperty"] ?? "").Equals("true", StringComparison.CurrentCultureIgnoreCase);

    // to do and save changes in database.
}

Change:

struct timeval, tvalBefore, tvalAfter; /* Looks like an attempt to
                                          delcare a variable with
                                          no name. */

to:

struct timeval tvalBefore, tvalAfter;

It is less likely (IMO) to make this mistake if there is a single declaration per line:

struct timeval tvalBefore;
struct timeval tvalAfter;

It becomes more error prone when declaring pointers to types on a single line:

struct timeval* tvalBefore, tvalAfter;

tvalBefore is a struct timeval* but tvalAfter is a struct timeval.

I got this error when I tried assigning a component property to a state property during instantiation

export default {
 props: ['value1'],
 data() {
  return {
   value2: this.value1 // throws the error
   }
  }, 
 created(){
  this.value2 = this.value1 // safe
 }
}

Mozila Firefox says that onreadystatechange is an alternative to DOMContentLoaded.

// alternative to DOMContentLoaded
document.onreadystatechange = function () {
    if (document.readyState == "complete") {
        initApplication();
    }
}

In DOMContentLoaded the Mozila's doc says:

The DOMContentLoaded event is fired when the document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading (the load event can be used to detect a fully-loaded page).

I think load event should be used for a full document+resources loading.

This is quite simple.

yourtextfield.frame = CGRectMake (yourXAxis, yourYAxis, yourWidth, yourHeight);

Declare your textfield as a gloabal property & change its frame where ever you want to do it in your code.

Happy Coding!

@SpiderCode's solution does not work with IE 11. Here is the best solution that I used henceforth in my code where I need browser detection for particular feature.

IE11 no longer reports as MSIE, according to this list of changes, it's intentional to avoid mis-detection.

What you can do if you really want to know it's IE is to detect the Trident/ string in the user agent if navigator.appName returns Netscape, something like (the untested);

Thanks to this answer

function isIE()
{
  var rv = -1;
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  else if (navigator.appName == 'Netscape')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  return rv == -1 ? false: true;
}

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

Had a similar issue, it turned out the listening port printed was different from what it actually was. Typos in the request string or listening function might make the target server appear to not exist.

The main reason you use the default queue over the main queue is to run tasks in the background.

For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
    //Background Thread
    dispatch_async(dispatch_get_main_queue(), ^(void){
        //Run UI Updates
    });
});

In order to create a ScrollView or ListView with a maxHeight you just need to create a Transparent LinearLayout around it with a height of what you want the maxHeight to be. You then set the ScrollView's Height to wrap_content. This creates a ScrollView that appears to grow until its height is equal to the parent LinearLayout.

Joakim Backman's answer is specific, but this may bring additional clarity to it.

There is a minor difference. As per SQL For Dummies, 8th Edition (2013):

The DECIMAL data type is similar to NUMERIC. ... The difference is that your implementation may specify a precision greater than what you specify — if so, the implementation uses the greater precision. If you do not specify precision or scale, the implementation uses default values, as it does with the NUMERIC type.

It seems that the difference on some implementations of SQL is in data integrity. DECIMAL allows overflow from what is defined based on some system defaults, where as NUMERIC does not.

Here

{int y=((year-1)%100);int c=(year-1)/100;}

you declare and initialize the variables y, c, but you don't used them at all before they run out of scope. That's why you get the unused message.

Later in the function, y, c are undeclared, because the declarations you made only hold inside the block they were made in (the block between the braces {...}).

Since you are probably running Windows (from looking at your tags), this would be the easiest way to open and show an image file from the console without installing extra stuff like PIL.

import os
os.system('start pic.png')

You can use numpy's polyfit. I use the following (you can safely remove the bit about coefficient of determination and error bounds, I just think it looks nice):

#!/usr/bin/python3

import numpy as np
import matplotlib.pyplot as plt
import csv

with open("example.csv", "r") as f:
    data = [row for row in csv.reader(f)]
    xd = [float(row[0]) for row in data]
    yd = [float(row[1]) for row in data]

# sort the data
reorder = sorted(range(len(xd)), key = lambda ii: xd[ii])
xd = [xd[ii] for ii in reorder]
yd = [yd[ii] for ii in reorder]

# make the scatter plot
plt.scatter(xd, yd, s=30, alpha=0.15, marker='o')

# determine best fit line
par = np.polyfit(xd, yd, 1, full=True)

slope=par[0][0]
intercept=par[0][1]
xl = [min(xd), max(xd)]
yl = [slope*xx + intercept  for xx in xl]

# coefficient of determination, plot text
variance = np.var(yd)
residuals = np.var([(slope*xx + intercept - yy)  for xx,yy in zip(xd,yd)])
Rsqr = np.round(1-residuals/variance, decimals=2)
plt.text(.9*max(xd)+.1*min(xd),.9*max(yd)+.1*min(yd),'$R^2 = %0.2f$'% Rsqr, fontsize=30)

plt.xlabel("X Description")
plt.ylabel("Y Description")

# error bounds
yerr = [abs(slope*xx + intercept - yy)  for xx,yy in zip(xd,yd)]
par = np.polyfit(xd, yerr, 2, full=True)

yerrUpper = [(xx*slope+intercept)+(par[0][0]*xx**2 + par[0][1]*xx + par[0][2]) for xx,yy in zip(xd,yd)]
yerrLower = [(xx*slope+intercept)-(par[0][0]*xx**2 + par[0][1]*xx + par[0][2]) for xx,yy in zip(xd,yd)]

plt.plot(xl, yl, '-r')
plt.plot(xd, yerrLower, '--r')
plt.plot(xd, yerrUpper, '--r')
plt.show()

The solution given by luschn and pillravi works fine unless you receive a Strict-Transport-Security header in the response.

Adding withCredentials: true will solve that issue.

  axios.post(session_url, {
    withCredentials: true,
    headers: {
      "Accept": "application/json",
      "Content-Type": "application/json"
    }
  },{
    auth: {
      username: "USERNAME",
      password: "PASSWORD"
  }}).then(function(response) {
    console.log('Authenticated');
  }).catch(function(error) {
    console.log('Error on Authentication');
  });

How do you run PowerShell built-in scripts inside of your scripts?

How do you use built-in scripts like

Get-Location
pwd
ls
dir
split-path
::etc...

Those are ran by your computer, automatically checking the path of the script.

Similarly, I can run my custom scripts by just putting the name of the script in the script-block

::sid.ps1 is a PS script I made to find the SID of any user
::it takes one argument, that argument would be the username
echo $(sid.ps1 jowers)


(returns something like)> S-X-X-XXXXXXXX-XXXXXXXXXX-XXX-XXXX


$(sid.ps1 jowers).Replace("S","X")

(returns same as above but with X instead of S)

Go on to the powershell command line and type

> $profile

This will return the path to a file that our PowerShell command line will execute every time you open the app.

It will look like this

C:\Users\jowers\OneDrive\Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1

Go to Documents and see if you already have a WindowsPowerShell directory. I didn't, so

> cd \Users\jowers\Documents
> mkdir WindowsPowerShell
> cd WindowsPowerShell
> type file > Microsoft.PowerShellISE_profile.ps1

We've now created the script that will launch every time we open the PowerShell App.

The reason we did that was so that we could add our own folder that holds all of our custom scripts. Let's create that folder and I'll name it "Bin" after the directories that Mac/Linux hold its scripts in.

> mkdir \Users\jowers\Bin

Now we want that directory to be added to our $env:path variable every time we open the app so go back to the WindowsPowerShell Directory and

> start Microsoft.PowerShellISE_profile.ps1

Then add this

$env:path += ";\Users\jowers\Bin"

Now the shell will automatically find your commands, as long as you save your scripts in that "Bin" directory.

Relaunch the powershell and it should be one of the first scripts that execute.

Run this on the command line after reloading to see your new directory in your path variable:

> $env:Path

Now we can call our scripts from the command line or from within another script as simply as this:

$(customScript.ps1 arg1 arg2 ...)

As you see we must call them with the .ps1 extension until we make aliases for them. If we want to get fancy.

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

You can set default values using Class.

Without Class Constructor:

interface IModal {
  content: string;
  form: string;
  href: string;
  isPopup: boolean;
};

class Modal implements IModal {
  content = "";
  form = "";
  href: string;  // will not be added to object
  isPopup = true;
}

const myModal = new Modal();
console.log(myModal); // output: {content: "", form: "", isPopup: true}

With Class Constructor

interface IModal {
  content: string;
  form: string;
  href: string;
  isPopup: boolean;
}

class Modal implements IModal {
  constructor() {
    this.content = "";
    this.form = "";
    this.isPopup = true;
  }

  content: string;

  form: string;

  href: string; // not part of constructor so will not be added to object

  isPopup: boolean;
}

const myModal = new Modal();
console.log(myModal); // output: {content: "", form: "", isPopup: true}

No need to do this:

while ($row = mysqli_fetch_array($result)) {
    $rows[] = $row;
}

You can directly do this:

while ($row = mysqli_fetch_array($result)) {
        echo "<option value='" . $row['value'] . "'>" . $row['value'] . "</option>";
    }

If you are using NVARCHAR just because a system stored procedure requires it, the most frequent occurrence being inexplicably sp_executesql, and your dynamic SQL is very long, you would be better off from performance perspective doing all string manipulations (concatenation, replacement etc.) in VARCHAR then converting the end result to NVARCHAR and feeding it into the proc parameter. So no, do not always use NVARCHAR!

i think phil is right request option is available till the page load. so if we want to sent value to another page we want to set the in the hidden tag or in side the session if you just need the value only on another page and not more than that then hidden tags are best option if you need that value on more than one page at that time session is the better option than hidden tags.

You could get around this issue using php. You only echo out the code for the popup on first page load.

The other way... Is to set a cookie which is basically a file that sits in your browser and contains some kind of data. On the first page load you would create a cookie. Then every page after that you check if your cookie is set. If it is set do not display the pop up. However if its not set set the cookie and display the popup.

Pseudo code:

if(cookie_is_not_set) {
    show_pop_up;
    set_cookie;
}

It was really hard to remember that

    int numberOfColumns = arr.length;
    int numberOfRows = arr[0].length;

Let's understand why this is so and how we can figure this out when we're given an array problem. From the below code we can see that rows = 4 and columns = 3:

    int[][] arr = { {1, 1, 1, 1}, 

                    {2, 2, 2, 2}, 

                    {3, 3, 3, 3} };

arr has multiple arrays in it, and these arrays can be arranged in a vertical manner to get the number of columns. To get the number of rows, we need to access the first array and consider its length. In this case, we access [1, 1, 1, 1] and thus, the number of rows = 4. When you're given a problem where you can't see the array, you can visualize the array as a rectangle with n X m dimensions and conclude that we can get the number of rows by accessing the first array then its length. The other one (arr.length) is for the columns.

After checking catalina.sh (for windows use the .bat versions of everything mentioned below)

#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

Also this

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc

So create a setenv.sh under CATALINA_BASE/bin (same dir where the catalina.sh resides). Edit the file and set the arguments to CATALINA_OPTS

For e.g. the file would look like this if you wanted to change the heap size

CATALINA_OPTS=-Xmx512m

Or in your case since you're using windows setenv.bat would be

set CATALINA_OPTS=-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5

To clear the added options later just delete setenv.bat/sh

If you're using local workspaces (TFS 2012+) you can now use the .tfignore file to exclude local folders and files from being checked in.

If you add that file to source control you can ensure others on your team share the same exclusion settings.

Full details on MSDN - http://msdn.microsoft.com/en-us/library/ms245454.aspx#tfignore

For the lazy:

You can configure which kinds of files are ignored by placing a text file called .tfignore in the folder where you want rules to apply. The effects of the .tfignore file are recursive. However, you can create .tfignore files in sub-folders to override the effects of a .tfignore file in a parent folder.

The following rules apply to a .tfignore file:

• # begins a comment line
• The * and ? wildcards are supported.
• A filespec is recursive unless prefixed by the \ character.
• ! negates a filespec (files that match the pattern are not ignored)

Example file:

# Ignore .cpp files in the ProjA sub-folder and all its subfolders
ProjA\*.cpp
# 
# Ignore .txt files in this folder 
\*.txt
#
# Ignore .xml files in this folder and all its sub-folders
*.xml
#
# Ignore all files in the Temp sub-folder
\Temp
#
# Do not ignore .dll files in this folder nor in any of its sub-folders
!*.dll

System.IO.File:

using System.IO;

{
    Console.WriteLine("file exists");
} 

In memory usage and speed.

When you call jsonstr = json.dumps(mydata) it first creates a full copy of your data in memory and only then you file.write(jsonstr) it to disk. So this is a faster method but can be a problem if you have a big piece of data to save.

When you call json.dump(mydata, file) -- without 's', new memory is not used, as the data is dumped by chunks. But the whole process is about 2 times slower.

Source: I checked the source code of json.dump() and json.dumps() and also tested both the variants measuring the time with time.time() and watching the memory usage in htop.

Only checked and checked="checked" are valid. Your other options depend on error recovery in browsers.

checked="yes" and checked="true" are particularly bad as they imply that checked="no" and checked="false" will set the default state to be unchecked … which they will not.

You need to convert it to milliseconds by multiplying the timestamp by 1000:

java.util.Date dateTime=new java.util.Date((long)timeStamp*1000);

It looks like window.open will take a Data URI as the location parameter.

So you can open it like this from the question: Opening PDF String in new window with javascript:

window.open("data:application/pdf;base64, " + base64EncodedPDF);

Here's an runnable example in plunker, and sample pdf file that's already base64 encoded.

Then on the server, you can convert the byte array to base64 encoding like this:

string fileName = @"C:\TEMP\TEST.pdf";
byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);

NOTE: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.

You should avoid the usage of $.ajaxSetup() as described in the docs. Use the following instead:

$(document).ajaxSend(function(event, jqXHR, ajaxOptions) {
    jqXHR.setRequestHeader('my-custom-header', 'my-value');
});

Eclipse by default does not know about your external Maven installation and uses the embedded one. Therefore in order for Eclipse to use your global settings you need to set it in menu Settings ? Maven ? Installations.

Sometimes you need to grep the process by name - in that case:

ps aux | grep simple-scan

Example output:

simple-scan  1090  0.0  0.1   4248  1432 ?        S    Jun11   0:00

It seems you don't even have to specify the compression any more. The following snippet loads the data from filename.zip into df.

import pandas as pd
df = pd.read_csv('filename.zip')

(Of course you will need to specify separator, header, etc. if they are different from the defaults.)

Here's where it gets confusing, the text states "If the balance factor of R is 1, it means the insertion occurred on the (external) right side of that node and a left rotation is needed". But from m understanding the text said (as I quoted) that if the balance factor was within [-1, 1] then there was no need for balancing?

Okay, epiphany time.

Consider what a rotation does. Let's think about a left rotation.

 P = parent
 O = ourself (the element we're rotating)
 RC = right child
 LC = left child (of the right child, not of ourself)

 P              10
  \               \
   O               15
    \                \
     RC               20
    /                /
   LC               18

          ?
 P              10
   \               \
     RC              20
   /               /
  O              15
   \               \
   LC              18

 basically, what happens is;

 1. our right child moves into our position
 2. we become the left child of our right child
 3. our right child's left child becomes our right

Now, the big thing you have to notice here - this left rotation HAS NOT CHANGED THE DEPTH OF THE TREE. We're no more balanced for having done it.

But - and here's the magic in AVL - if we rotated the right child to the right FIRST, what we'd have is this...

 P
  \
   O
    \
     LC
      \
       RC

And NOW if we rotate O left, what we get is this...

 P
   \
     LC
    /  \
   O   RC

Magic! we've managed to get rid of a level of the tree - we've made the tree balanced.

Balancing the tree means getting rid of excess depth, and packing the upper levels more completely - which is exactly what we've just done.

That whole stuff about single/double rotations is simply that you have to have your subtree looking like this;

 P
  \
   O
    \
     LC
      \
       RC

before you rotate - and you may have to do a right rotate to get into that state. But if you're already in that state, you only need to do the left rotate.

Probably somewhere you have DBconnection->close(); and then some queries try to execute .

Hint: It's sometimes mistake to insert ...->close(); in __destruct() (because __destruct is event, after which there will be a need for execution of queries)

Add Beyond Compare as your difftool in Git and add an alias for diffdir as:

git config --global alias.diffdir = "difftool --dir-diff --tool=bc3 --no-prompt"

Get the gitdiff as:

git diffdir 4bc7ba80edf6  7f566710c7

Reference: Compare entire directories w git difftool + Beyond Compare

I know this question has been and gone, but if anyone else stumbled across this I wanted to let them know. This may sound an unintuitive thing to do but you could use a button with clickable set to false or what ever. This is because a button allows one to set drawableLeft, drawableRight, drawableTop etc in addition to text.

  <Button
  android:id="@+id/button1"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@drawable/border_box1"
  android:drawableLeft="@drawable/ar9_but_desc"
  android:padding="20dp"
  android:text="@string/ar4_button1"
  android:textColor="@color/white"
  android:textSize="24sp" />

New Info: A button can have icons in drawableLeft, drawableRight, drawableTop, and drawableBottom. This makes a standard button much more flexible than an image button. The left, right, top etc is the relation to the text in the button. You can have multiple drawables on the button for example one left, one right and the text in the middle.

The git cherry-pick <commit> command allows you to take a single commit (from whatever branch) and, essentially, rebase it in your working branch.

Chapter 5 of the Pro Git book explains it better than I can, complete with diagrams and such. (The chapter on Rebasing is also good reading.)

Lastly, there are some good comments on the cherry-picking vs merging vs rebasing in another SO question.

If you are using Angular 7 or a previous version and you dont' have access to the clear() method, there is a way to achieve that without doing any loop:

yourFormGroup.controls.youFormArrayName = new FormArray([]);

$data = array( 
    'name'      => $_POST['name'] , 
    'groupname' => $_POST['groupname'], 
    'age'       => $_POST['age']
);

$this->db->where('id', $_POST['id']);

$this->db->update('tbl_user', $data);

See Java tools documentation for:

• java command¹/javaw command²

1. The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.
2. The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear.

• javaws command, the "Java Web Start command"

The javaws command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP). Java Web Start launches Java applications/applets hosted on a network.

If a JNLP file is specified, javaws will launch the Java application/applet specified in the JNLP file.

The javaws launcher has a set of options that are supported in the current release. However, the options may be removed in a future release.

See also JDK 9 Release Notes Deprecated APIs, Features, and Options:

Java Deployment Technologies are deprecated and will be removed in a future release
Java Applet and WebStart functionality, including the Applet API, the Java plug-in, the Java Applet Viewer, JNLP and Java Web Start, including the javaws tool, are all deprecated in JDK 9 and will be removed in a future release.

Lets take a vector 'point' which has numbers from 1 to 5

point = c(1,2,3,4,5)

if we want to append a number 6 anywhere inside the vector then below command may come handy

i) Vectors

new_var = append(point, 6 ,after = length(point))

ii) columns of a table

new_var = append(point, 6 ,after = length(mtcars$mpg))

The command append takes three arguments:

1. the vector/column to be modified.
2. value to be included in the modified vector.
3. a subscript, after which the values are to be appended.

simple...!! Apologies in case of any...!

I had a similar kind of issue, but with some differences...

In my case, my main form has a Control (vendor) which value I used to update a Query in my DB, using the following code:

Sub Set_Qry_PedidosRealizadosImportados_frm(Vd As Long)
Dim temp_qry As DAO.QueryDef

'Procedimento para ajustar o codigo do cliente na Qry_Pedidos realizados e importados
'Procedure to adjust the code of the client on Qry_Pedidos realizados e importados
Set temp_qry = CurrentDb.QueryDefs("Qry_Pedidos realizados e importados")
temp_qry.SQL = "SELECT DISTINCT " & _
            "[Qry_Pedidos distintos].[Codigo], " & _
            "[Qry_Pedidos distintos].[Razao social], " & _
            "COUNT([Qry_Pedidos distintos].[Pedido Avante]) As [Pedidos realizados], " & _
            "SUM(IIf(NZ([Qry_Pedidos distintos].[Pedido Flexx], 0) > 1, 1, 0)) As [Pedidos Importados] " & _
            "FROM [Qry_Pedidos distintos] " & _
            "WHERE [Qry_Pedidos distintos].Vd = " & Vd & _
            " Group BY " & _
            "[Qry_Pedidos distintos].[Razao social], " & _
            "[Qry_Pedidos distintos].[Codigo];"
End Sub

Since the beginning my subform record source was the query named "Qry_Pedidos realizados e importados".

But the only way I could update the subform data inside the main form context was to refresh the data source of the subform to it self, like posted bellow:

Private Sub cmb_vendedor_v1_Exit(Cancel As Integer)
'Codigo para atualizar o comando SQL da query
'Code to update the SQL statement of the query 
    Call Set_Qry_Pedidosrealizadosimportados_frm(Me.cmb_vendedor_v1.Value)

'Codigo para forçar o Access a aceitar o novo comando SQL
'Code to force de Access to accept the new sql statement
    Me!Frm_Pedidos_realizados_importados.Form.RecordSource = "Qry_Pedidos realizados e importados"
End Sub

No refresh, recalc, requery, etc, was necessary after all...

• Make it immutable;
• Make it canonical, meaning 6/4 becomes 3/2 (greatest common divisor algorithm is useful for this);
• Call it Rational, since what you're representing is a rational number;
• You could use BigInteger to store arbitrarilyy-precise values. If not that then long, which has an easier implementation;
• Make the denominator always positive. Sign should be carried by the numerator;
• Extend Number;
• Implement Comparable<T>;
• Implement equals() and hashCode();
• Add factory method for a number represented by a String;
• Add some convenience factory methods;
• Add a toString(); and
• Make it Serializable.

use js split() method to create an array

var keywords = $('#searchKeywords').val().split(",");

then loop through the array using jQuery.each() function. as the documentation says:

In the case of an array, the callback is passed an array index and a corresponding array value each time

$.each(keywords, function(i, keyword){
   console.log(keyword);
});

Yes, there are a number of ways that you can do this. The "fastest" way would be to add CSS to the div similar to the following

#term-defs {
height: 300px;
overflow: scroll; }

This will force the div to be scrollable, but this might not get the best effect. Another route would be to absolute fix the position of the items at the top, you can play with this by doing something like this.

#top {
  position: fixed;
  top: 0;
  left: 0;
  z-index: 999;
  width: 100%;
  height: 23px;
}

This will fix it to the top, on top of other content with a height of 23px.

The final implementation will depend on what effect you really want.

My simple, simple, simple approach! =D

Code

string_to_test = "The criminals stole $1,000,000 in jewels."
chars_to_check = ["$", ",", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
for char in chars_to_check:
    if char in string_to_test:
        print("Char \"" + char + "\" detected!")

Output

Char "$" detected!
Char "," detected!
Char "0" detected!
Char "1" detected!

Thanks!

just configure your log4j property file path in beginning of main method: e.g.: PropertyConfigurator.configure("D:\files\log4j.properties");

The only problem could be if one day

map[key] = value

will transform to -

map[key]++;

and that will cause a KeyNotFoundException.

You must use

list.remove(indexYouWantToReplace);

first.

Your elements will become like this. [zero, one, three]

then add this

list.add(indexYouWantedToReplace, newElement)

Your elements will become like this. [zero, one, new, three]

Here is an example code to compress a Whole Directory(including sub files and sub directories), it's using the walk file tree feature of Java NIO.

import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.*;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZipCompress {
    public static void compress(String dirPath) {
        final Path sourceDir = Paths.get(dirPath);
        String zipFileName = dirPath.concat(".zip");
        try {
            final ZipOutputStream outputStream = new ZipOutputStream(new FileOutputStream(zipFileName));
            Files.walkFileTree(sourceDir, new SimpleFileVisitor<Path>() {
                @Override
                public FileVisitResult visitFile(Path file, BasicFileAttributes attributes) {
                    try {
                        Path targetFile = sourceDir.relativize(file);
                        outputStream.putNextEntry(new ZipEntry(targetFile.toString()));
                        byte[] bytes = Files.readAllBytes(file);
                        outputStream.write(bytes, 0, bytes.length);
                        outputStream.closeEntry();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    return FileVisitResult.CONTINUE;
                }
            });
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

To use this, just call

ZipCompress.compress("target/directoryToCompress");

and you'll get a zip file directoryToCompress.zip

Let us say we are migrating Jenkins LTS from PC1 to PC2 (irrispective of LTS version is same of upgraded). It is easy to use ThinBackUp Plugin for migration or Upgrade of Jenkins version.

Step1: Prepare PC1 for migration

• Manage Jenkins -> ThinbackUp -> Setting
• Select correct options and directory for backup
• If you need a job history and artifacts need to be added then please select 'Back build results' option as well.

• Go back click on Backup Now.

Note: This Thinbackup will also take Plugin Backup which is optional.

• Check the ThinbackUp folder must have a folder with current date and timestamp. (wait for couple of minutes it might take some time.)
• You are ready with your back, .zip it and copy to PARTICULAR (which will be 'Backup directory') directory in PC2.
• Unzip ThinbackUp zipped folder.
• Stop Jenkins Service in PC1.

Step2: Install Jenkins (Install using .war file or Paste archived version) in PC2.

• Create Jenkins Service using command sc create <Jenkins_PC2Servicename> binPath="<Path_to_Jenkinsexe>/jenkins.exe"
• Modify JENKINS_HOME/jenkins.xml if needed in PC2.
• Run windows service <Jenkins_PC2Servicename> in PC2
• Manage Jenkins -> ThinbackUp -> Setting
• Make sure that you PERTICULAR path from step1 as Backup Directory in ThinBackup settings.
• ThinbackUp -> Restore will give you a Dropdown list, choose a right backup (identify with date and timestamp).

• Wait for some minutes and you have latest backup configurations including jobs history and plugins in PC2.
• In case if there are additional changes needed in JENKINS_HOME/Jenkins.xml (coming from PC1 ThinbackUp which is not needed) then this modification need to do manually.

NOTE: If you are using Database setting of SCM in your Jenkins jobs then you need to take extra care as all SCM plugins do not support to carry Database settings with the help of ThinbackUp plugin. e.g. If you are using PTC Integrity SCM Plugin, and some Jenkins jobs are using DB using Integrity, then it will create a directory JENKINS_Home/IntegritySCM, ThinbackUp will not include this DB while taking backup.

Solution: Directly Copy this JENKINS_Home/IntegritySCM folder from PC1 to PC2.

Inline methods are simply a compiler optimization where the code of a function is rolled into the caller.

There's no mechanism by which to do this in C#, and they're to be used sparingly in languages where they are supported -- if you don't know why they should be used somewhere, they shouldn't be.

Edit: To clarify, there are two major reasons they need to be used sparingly:

1. It's easy to make massive binaries by using inline in cases where it's not necessary
2. The compiler tends to know better than you do when something should, from a performance standpoint, be inlined

It's best to leave things alone and let the compiler do its work, then profile and figure out if inline is the best solution for you. Of course, some things just make sense to be inlined (mathematical operators particularly), but letting the compiler handle it is typically the best practice.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

I had same problem, for me npm install request --save solved the problem. Hope it helps.

Same problem happened to me as well and the .project file was not there in the project. I copied a .project file from an existing android project and replace the project name with the name of the project I am trying to import. Then using File -> Import -> Existing projects into workspace I was able to import the project.

speaking from computation and memory bound point of view (scientific computing) 4000 threads will make application run really slow. Part of the problem is a very high overhead of context switching and most likely very poor memory locality.

But it also depends on your architecture. From where I heard Niagara processors are suppose to be able to handle multiple threads on a single core using some kind of advanced pipelining technique. However I have no experience with those processors.

when I sended a question to a Regexbuddy (regex developer application) forum, I got more exact reply to my \s Java question:

"Message author: Jan Goyvaerts

In Java, the shorthands \s, \d, and \w only include ASCII characters. ... This is not a bug in Java, but simply one of the many things you need to be aware of when working with regular expressions. To match all Unicode whitespace as well as line breaks, you can use [\s\p{Z}] in Java. RegexBuddy does not yet support Java-specific properties such as \p{javaSpaceChar} (which matches the exact same characters as [\s\p{Z}]).

... \s\s will match two spaces, if the input is ASCII only. The real problem is with the OP's code, as is pointed out by the accepted answer in that question."

In your image you've putting the padding outside the child. This is not the case. Padding adds to the width of an element, so if you add padding and give it a width of 100% it will have a width of 100% + padding. In order to what you are wanting you just need to either add padding to the parent div, or add a margin to the inner div. Because divs are block-level elements they will automatically expand to the width of their parent.

Try:

git stash
git checkout -b new-branch
git stash apply

Once you read what What Every Computer Scientist Should Know About Floating-Point Arithmetic you could use the .toFixed() function:

var result = parseFloat('2.3') + parseFloat('2.4');
alert(result.toFixed(2));?

Well generally you shouldn't need to classify an element specified by id, because id is always unique, but if you really need to, the following should work:

div#content.sectionA {
    /* ... */
}

This worked for me...

N.B : IF YOU ARE USING PHPSTORM

I spent an hour trying to solve this problem, thinking that it was my php server problem, So i set 'always_populate_raw_post_data' to '-1' in php.ini and nothing worked.

Until i found out that using phpStorm built in server is what causing the problem as detailed in the answer here : Answer by LazyOne Here , So i thought about sharing it.

Suppose the data is in the B column, write in the C column the formula:

=SUBSTITUTE(B1," ","")

Copy&Paste the formula in the whole C column.

edit: using commas or semicolons as parameters separator depends on your regional settings (I have to use the semicolons). This is weird I think. Thanks to @tocallaghan and @pablete for pointing this out.

You could try to sort descending "sort LastWriteTime -Descending" and then "select -first 1." Not sure which one is faster

Only this worked for me:

searchKeyword.replace(/'/g, "\\\'");//searchKeyword contains "d'av"

So, the result variable will contain "d\'av".

I don't know why with the RegEx didn't work, maybe because of the JS framework that I'm using (Backbone.js)

TL;DR: When using functional idioms it's better to write functional code

As many people have pointed out, in Python lambdas assignment is not allowed. In general when using functional idioms your better off thinking in a functional manner which means wherever possible no side effects and no assignments.

Here is functional solution which uses a lambda. I've assigned the lambda to fn for clarity (and because it got a little long-ish).

from operator import add
from itertools import ifilter, ifilterfalse
fn = lambda l, pred: add(list(ifilter(pred, iter(l))), [ifilterfalse(pred, iter(l)).next()])
objs = [Object(name=""), Object(name="fake_name"), Object(name="")]
fn(objs, lambda o: o.name != '')

You can also make this deal with iterators rather than lists by changing things around a little. You also have some different imports.

from itertools import chain, islice, ifilter, ifilterfalse
fn = lambda l, pred: chain(ifilter(pred, iter(l)), islice(ifilterfalse(pred, iter(l)), 1))

You can always reoganize the code to reduce the length of the statements.

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).

1. I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.

   [Desktop Entry]
   Name=No name
   Encoding=UTF-8
   Version=1.0
   Exec=vncconfig -nowin
   X-GNOME-Autostart-enabled=true
   

2. Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.

3. Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.

You need to use a ServerSocket. You can find an explanation here.

One can use the following method to convert an Exception stack trace to String. This class is available in Apache commons-lang which is most common dependent library with many popular open sources

org.apache.commons.lang.exception.ExceptionUtils.getStackTrace(Throwable)

I have a Windows 7 client on a Mac host and this post was VERY helpful. Thanks.

I would add that I didn't use gparted. I did this:

1. Launch new enlarged vmdk image.
2. Go to Start and right click Computer and select Manage.
3. Click Disk Management
4. You should see some grayed space on your (in my case) C drive
5. Right click the C drive and select Extend Volume.
6. Choose size and go

Sweet! I preferred that to using a 3rd party tool with warnings about data loss.

Cheers!

Try restarting your docker environment using:

systemctl restart docker

Can em.flush() cause any harm when using it within a transaction?

Yes, it may hold locks in the database for a longer duration than necessary.

Generally, When using JPA you delegates the transaction management to the container (a.k.a CMT - using @Transactional annotation on business methods) which means that a transaction is automatically started when entering the method and commited / rolled back at the end. If you let the EntityManager handle the database synchronization, sql statements execution will be only triggered just before the commit, leading to short lived locks in database. Otherwise your manually flushed write operations may retain locks between the manual flush and the automatic commit which can be long according to remaining method execution time.

Notes that some operation automatically triggers a flush : executing a native query against the same session (EM state must be flushed to be reachable by the SQL query), inserting entities using native generated id (generated by the database, so the insert statement must be triggered thus the EM is able to retrieve the generated id and properly manage relationships)

@alex-dima's solution from 2015 will change tab sizes and spaces for all files and @Tricky's solution from 2016 appears to only change the settings for the current file.

As of 2017, I found another solution that works on a per-language basis. Visual Studio Code was not using the proper tab sizes or space settings for Elixir, so I found that I could change the settings for all Elixir files.

I clicked on the language in the status bar ("Elixir" in my case), chose "Configure 'Elixir' language based settings...", and edited the Elixir-specific language settings. I just copied the "editor.tabSize" and "editor.insertSpaces" settings from the default settings on the left (I'm so glad those are shown) and then modified them on the right.

It worked great, and now all Elixir language files use the proper tab size and space settings.

The most you can get is:

select#xyz {
   border:0px;
   outline:0px;
}

You cannot style it completely, but you can try something like

select#xyz {
  -webkit-appearance: button;
  -webkit-border-radius: 2px;
  -webkit-box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
  -webkit-padding-end: 20px;
  -webkit-padding-start: 2px;
  -webkit-user-select: none;
  background-image: url(../images/select-arrow.png), 
    -webkit-linear-gradient(#FAFAFA, #F4F4F4 40%, #E5E5E5);
  background-position: center right;
  background-repeat: no-repeat;
  border: 1px solid #AAA;
  color: #555;
  font-size: inherit;
  margin: 0;
  overflow: hidden;
  padding-top: 2px;
  padding-bottom: 2px;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Only want to clone the structure of table:

CREATE TABLE foo SELECT * FROM bar WHERE 1 = 2;

Also wants to copy the data:

CREATE TABLE foo as SELECT * FROM bar;

If your source data is larger than your target field and you just want to cut off any extra characters, but you don't want to turn off strict mode or change the target field's size, then just cut the data down to the size you need with LEFT(field_name,size).

INSERT INTO Department VALUES
(..., LEFT('There is some text here',30),...), (..., LEFT('There is some more text over here',30),...);

I used "30" as an example of your target field's size.

In some of my code, it's easy to get the target field's size and do this. But if your code makes that hard, then go with one of the other answers.

A more general answer would be to import java.util.Date, then when you need to set a timestamp equal to the current date, simply set it equal to new Date().

From the Express.js Guide: View Rendering

View filenames take the form Express.ENGINE, where ENGINE is the name of the module that will be required. For example the view layout.ejs will tell the view system to require('ejs'), the module being loaded must export the method exports.render(str, options) to comply with Express, however app.register() can be used to map engines to file extensions, so that for example foo.html can be rendered by jade.

So either you create your own simple renderer or you just use jade:

 app.register('.html', require('jade'));

More about app.register.

Note that in Express 3, this method is renamed app.engine

Your modification of sys.path assumes the current working directory is always in main/. This is not the case. Instead, just add the parent directory to sys.path:

import sys
import os.path

sys.path.append(os.path.join(os.path.dirname(__file__), '..'))
import gen_py.lib

Don't forget to include a file __init__.py in gen_py and lib - otherwise, they won't be recognized as Python modules.

Use isset()

$matchFound = (isset($_GET["id"]) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

EDIT: This is added for the completeness sake. $_GET in php is a reserved variable that is an associative array. Hence, you could also make use of 'array_key_exists(mixed $key, array $array)'. It will return a boolean that the key is found or not. So, the following also will be okay.

$matchFound = (array_key_exists("id", $_GET)) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

If you want ex. change all country codes in .json file from uppercase to lowercase:

ctrl+h
alt+r
alt+c

Find: ([A-Z]{2,})
Replace: $1

alt+enter
F1
type: lower -> select toLoweCase
ctrl+alt+enter

ex file:

[
 {"id": "PL", "name": "Poland"},
 {"id": "NZ", "name": "New Zealand"},
 ...
]

function writeCookie(name,value,days) {
    var date, expires;
    if (days) {
        date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires=" + date.toGMTString();
            }else{
        expires = "";
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}

insert into bookmarks (users_id, lessoninfo_id)

select 1, 167
EXCEPT
select user_id, lessoninfo_id
from bookmarks
where user_id=1
and lessoninfo_id=167;

This is the fastest way.

For some other SQL engines, you can use a Dummy table containing 1 record. e.g:

select 1, 167 from ONE_RECORD_DUMMY_TABLE

The module timeit is useful for this and is included in the standard Python distribution.

Example:

import timeit
timeit.Timer('for i in xrange(10): oct(i)').timeit()

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

HTML + JQuery: A link that submits a hidden form with POST.

Since I spent a lot of time to understand all these answers, and since all of them have some interesting details, here is the combined version that finally worked for me and which I prefer for its simplicity.

My approach is again to create a hidden form and to submit it by clicking a link somewhere else in the page. It doesn't matter where in the body of the page the form will be placed.

The code for the form:

<form id="myHiddenFormId" action="myAction.php" method="post" style="display: none">
  <input type="hidden" name="myParameterName" value="myParameterValue">
</form>

Description:

The display: none hides the form. You can alternatively put it in a div or another element and set the display: none on the element.

The type="hidden" will create an fild that will not be shown but its data will be transmitted to the action eitherways (see W3C). I understand that this is the simplest input type.

The code for the link:

<a href="" onclick="$('#myHiddenFormId').submit(); return false;" title="My link title">My link text</a>

Description:

The empty href just targets the same page. But it doesn't really matter in this case since the return false will stop the browser from following the link. You may want to change this behavior of course. In my specific case, the action contained a redirection at the end.

The onclick was used to avoid using href="javascript:..." as noted by mplungjan. The $('#myHiddenFormId').submit(); was used to submit the form (instead of defining a function, since the code is very small).

This link will look exactly like any other <a> element. You can actually use any other element instead of the <a> (for example a <span> or an image).

The default value of any enum is zero. So if you want to set one enumerator to be the default value, then set that one to zero and all other enumerators to non-zero (the first enumerator to have the value zero will be the default value for that enum if there are several enumerators with the value zero).

enum Orientation
{
    None = 0, //default value since it has the value '0'
    North = 1,
    East = 2,
    South = 3,
    West = 4
}

Orientation o; // initialized to 'None'

If your enumerators don't need explicit values, then just make sure the first enumerator is the one you want to be the default enumerator since "By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1." (C# reference)

enum Orientation
{
    None, //default value since it is the first enumerator
    North,
    East,
    South,
    West
}

Orientation o; // initialized to 'None'

Found the answer on a blog and it's as simple as:

strtotime(date("Y"."-01-01")) -strtotime($newdate))/86400

And you'll get the days between the 2 dates.

If you have multiple files and you don't want to have to type each file, I would recommend that you follow these simple steps (I am using clang-3.8 but you can use any other version):

1. generate all .ll files

   clang-3.8 -S -emit-llvm *.c
   

2. link them into a single one

   llvm-link-3.8 -S -v -o single.ll *.ll
   

3. (Optional) Optimise your code (maybe some alias analysis)

   opt-3.8 -S -O3 -aa -basicaaa -tbaa -licm single.ll -o optimised.ll
   

4. Generate assembly (generates a optimised.s file)

   llc-3.8 optimised.ll
   

5. Create executable (named a.out)

   clang-3.8 optimised.s
   

I encountered the same error, and was able to solve it as follows:

1. composer diagnose to see if something is wrong with the version of composer installed
2. composer self-update to install the latest version
3. composer update to update your composer.json file.

You need to replace the adbd binary in the boot.img/sbin/ folder to one that is su capable. You will also have to make some default.prop edits too.

Samsung seems to make this more difficult than other vendors. I have some adbd binaries you can try but it will require the knowledge of de-compiling and re-compiling the boot.img with the new binary. Also, if you have a locked bootloader... this is not gonna happen.

Also Chainfire has an app that will grant adbd root permission in the play store: https://play.google.com/store/apps/details?id=eu.chainfire.adbd&hl=en

Lastly, if you are trying to write a windows script with SU permissions you can do this buy using the following command style... However, you will at least need to grant (on the phone) SU permissions the frist time its ran...

adb shell "su -c ls" <-list working directory with su rights. adb shell "su -c echo anytext > /data/test.file"

These are just some examples. If you state specifically what you are trying to accomplish I may be able to give more specific advice

I set the NODEJS variable in the system control panel but the only thing that worked to set the path was to do it from command line as administrator.

SET PATH=%NODEJS%;%PATH%

Another trick is that once you set the path you must close the console and open a new one for the new path to be taken into account.

However for the regular user to be able to use node I had to run set path again not as admin and restart the computer

Attention, wrong answer coming! But anyone without apache libraries or so might find

compileSdkVersion 23
buildToolsVersion "23.0.0"



//...


dependencies {
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:design:23.0.0'    

}

helpful, it did the trick for me.

Use the attribute selector

[id^=product]{property:value}

Simple and short answer to your question is

Please add following line into your "Execute shell" Build step.

#!/bin/sh

Now let me explain you the reason why we require this line for "Execute Shell" build job.

By default Jenkins take /bin/sh -xe and this means -x will print each and every command.And the other option -e, which causes shell to stop running a script immediately when any command exits with non-zero (when any command fails) exit code.

So by adding the #!/bin/sh will allow you to execute with no option.

This simple filtering can be achieved in many ways with Python. The best approach is to use "list comprehensions" as follows:

>>> lst = ['a', 'ab', 'abc', 'bac']
>>> [k for k in lst if 'ab' in k]
['ab', 'abc']

Another way is to use the filter function. In Python 2:

>>> filter(lambda k: 'ab' in k, lst)
['ab', 'abc']

In Python 3, it returns an iterator instead of a list, but you can cast it:

>>> list(filter(lambda k: 'ab' in k, lst))
['ab', 'abc']

Though it's better practice to use a comprehension.

If you're just playing around in local mode, you can drop metastore DB and reinstate it:

rm -rf metastore_db/
$HIVE_HOME/bin/schematool -initSchema -dbType derby

using webpack and vue loader you can do something like this

it waits for the external script to load before creating the component, so globar vars etc are available in the component

components: {
 SomeComponent: () => {
  return new Promise((resolve, reject) => {
   let script = document.createElement('script')
   script.onload = () => {
    resolve(import(someComponent))
   }
   script.async = true
   script.src = 'https://maps.googleapis.com/maps/api/js?key=APIKEY&libraries=places'
   document.head.appendChild(script)
  })
 }
},

**write this before adding view to dialog.**

dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);

There are a few options...

1. Override the push method

Object.defineProperty(myArray, "push", {
  enumerable: false, // hide from for...in
  configurable: false, // prevent further meddling...
  writable: false, // see above ^
  value: function () {
    for (var i = 0, n = this.length, l = arguments.length; i < l; i++, n++) {          
      RaiseMyEvent(this, n, this[n] = arguments[i]); // assign/raise your event
    }
    return n;
  }
});

_{¹ Alternatively, if you'd like to target all arrays, you could override Array.prototype.push(). Use caution, though; other code in your environment may not like or expect that kind of modification. Still, if a catch-all sounds appealing, just replace myArray with Array.prototype.}

Now, that's just one method and there are lots of ways to change array content. We probably need something more comprehensive...

2. Create a custom observable array

function ObservableArray(items) {
  var _self = this,
    _array = [],
    _handlers = {
      itemadded: [],
      itemremoved: [],

          });
        }
      });
    }
  }

That gets us closer but it's still not bullet proof... which brings us to:

3. Proxies

A Proxy object offers another solution to the modern browser. It allows you to intercept method calls, accessors, etc. Most importantly, you can do this without even providing an explicit property name... which would allow you to test for an arbitrary, index-based access/assignment. You can even intercept property deletion. Proxies would effectively allow you to inspect a change before deciding to allow it... in addition to handling the change after the fact.

Here's a stripped down sample:

(function() {

  if (!("Proxy" in window)) {
    console.warn("Your browser doesn't support Proxies.");
    return;
  }

  // our backing array
  var array = ["a", "b", "c", "d"];

  // a proxy for our array
  var proxy = new Proxy(array, {
    apply: function(target, thisArg, argumentsList) {
      return thisArg[target].apply(this, argumentList);
    },
    deleteProperty: function(target, property) {
      console.log("Deleted %s", property);
      return true;
    },
    set: function(target, property, value, receiver) {      
      target[property] = value;
      console.log("Set %s to %o", property, value);
      return true;
    }
  });

  console.log("Set a specific index..");
  proxy[0] = "x";

  console.log("Add via push()...");
  proxy.push("z");

  console.log("Add/remove via splice()...");
  proxy.splice(1, 3, "y");

  console.log("Current state of array: %o", array);

})();

I would implement it like this:

public static class EnumerableExtensions
{
    public static int IndexOf<T>(this IEnumerable<T> obj, T value)
    {
        return obj.IndexOf(value, null);
    }

    public static int IndexOf<T>(this IEnumerable<T> obj, T value, IEqualityComparer<T> comparer)
    {
        comparer = comparer ?? EqualityComparer<T>.Default;
        var found = obj
            .Select((a, i) => new { a, i })
            .FirstOrDefault(x => comparer.Equals(x.a, value));
        return found == null ? -1 : found.i;
    }
}

Use strstr for this.

http://www.cplusplus.com/reference/clibrary/cstring/strstr/

So, you'd write it like..

char *sent = "this is my sample example";
char *word = "sample";

char *pch = strstr(sent, word);

if(pch)
{
    ...
}

There should be an easier way to do this, but, depending on what you're trying to do, the best route might be to convert to a regular Python datetime object:

datetime64Obj = np.datetime64('2002-07-04T02:55:41-0700')
print datetime64Obj.astype(object).year
# 2002
print datetime64Obj.astype(object).day
# 4

Based on comments below, this seems to only work in Python 2.7.x and Python 3.6+

Why using a selfmade highlighting function is a bad idea

The reason why it's probably a bad idea to start building your own highlighting function from scratch is because you will certainly run into issues that others have already solved. Challenges:

• You would need to remove text nodes with HTML elements to highlight your matches without destroying DOM events and triggering DOM regeneration over and over again (which would be the case with e.g. innerHTML)
• If you want to remove highlighted elements you would have to remove HTML elements with their content and also have to combine the splitted text-nodes for further searches. This is necessary because every highlighter plugin searches inside text nodes for matches and if your keywords will be splitted into several text nodes they will not being found.
• You would also need to build tests to make sure your plugin works in situations which you have not thought about. And I'm talking about cross-browser tests!

Sounds complicated? If you want some features like ignoring some elements from highlighting, diacritics mapping, synonyms mapping, search inside iframes, separated word search, etc. this becomes more and more complicated.

Use an existing plugin

When using an existing, well implemented plugin, you don't have to worry about above named things. The article 10 jQuery text highlighter plugins on Sitepoint compares popular highlighter plugins. This includes plugins of answers from this question.

Have a look at mark.js

mark.js is such a plugin that is written in pure JavaScript, but is also available as jQuery plugin. It was developed to offer more opportunities than the other plugins with options to:

• search for keywords separately instead of the complete term
• map diacritics (For example if "justo" should also match "justò")
• ignore matches inside custom elements
• use custom highlighting element
• use custom highlighting class
• map custom synonyms
• search also inside iframes
• receive not found terms

DEMO

Alternatively you can see this fiddle.

Usage example:

// Highlight "keyword" in the specified context
$(".context").mark("keyword");

// Highlight the custom regular expression in the specified context
$(".context").markRegExp(/Lorem/gmi);

It's free and developed open-source on GitHub (project reference).

Here is it: http://www.htmlcssvqs.com/8ed/examples/chapter-17/webm-video-with-autoplay-loop.html You have to add the tags: autoplay="autoplay" loop="loop" or just "autoplay" and "loop".

I used the following steps to create a new hot fix branch from a Tag.

Syntax

git checkout -b <New Branch Name> <TAG Name>

Steps to do it.

1. git checkout -b NewBranchName v1.0
2. Make changes to pom / release versions
3. Stage changes
4. git commit -m "Update pom versions for Hotfix branch"
5. Finally push your newly created branch to remote repository.

git push -u origin NewBranchName

I hope this would help.

If you need to deal with data.frames that include factors you can use:

df = data.frame(v1=letters[1:5],v2=1:5,v3=letters[10:14],v4=as.factor(letters[1:5]),v5=runif(5),stringsAsFactors=FALSE)

df
    v1 v2 v3 v4        v5
    1  a  1  j  a 0.1774909
    2  b  2  k  b 0.4405019
    3  c  3  l  c 0.7042878
    4  d  4  m  d 0.8829965
    5  e  5  n  e 0.9702505


sapply(df,class)
         v1          v2          v3          v4          v5
"character"   "integer" "character"    "factor"   "numeric"

Use mutate_each_ to convert factors to character then convert all to uppercase

   upper_it = function(X){X %>% mutate_each_( funs(as.character(.)), names( .[sapply(., is.factor)] )) %>%
   mutate_each_( funs(toupper), names( .[sapply(., is.character)] ))}   # convert factor to character then uppercase

Gives

  upper_it(df)
      v1 v2 v3 v4
    1  A  1  J  A
    2  B  2  K  B
    3  C  3  L  C
    4  D  4  M  D
    5  E  5  N  E

While

sapply( upper_it(df),class)
         v1          v2          v3          v4          v5
"character"   "integer" "character" "character"   "numeric"

Here is couple of ways to calculate length of variable :

echo ${#VAR}
echo -n $VAR | wc -m
echo -n $VAR | wc -c
printf $VAR | wc -m
expr length $VAR
expr $VAR : '.*'

and to set the result in another variable just assign above command with back quote into another variable as following:

otherVar=`echo -n $VAR | wc -m`   
echo $otherVar

http://techopsbook.blogspot.in/2017/09/how-to-find-length-of-string-variable.html

Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect, or using udfs. Unfortunately this only works for spark version 2.1 and above, because it requires the posexplode function.

Suppose you had the following DataFrame:

df = spark.createDataFrame(
    [
        [1, 'A, B, C, D'], 
        [2, 'E, F, G'], 
        [3, 'H, I'], 
        [4, 'J']
    ]
    , ["num", "letters"]
)
df.show()
#+---+----------+
#|num|   letters|
#+---+----------+
#|  1|A, B, C, D|
#|  2|   E, F, G|
#|  3|      H, I|
#|  4|         J|
#+---+----------+

Split the letters column and then use posexplode to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr to grab the element at index pos in this array.

import pyspark.sql.functions as f

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .show()
#+---+------------+---+---+
#|num|     letters|pos|val|
#+---+------------+---+---+
#|  1|[A, B, C, D]|  0|  A|
#|  1|[A, B, C, D]|  1|  B|
#|  1|[A, B, C, D]|  2|  C|
#|  1|[A, B, C, D]|  3|  D|
#|  2|   [E, F, G]|  0|  E|
#|  2|   [E, F, G]|  1|  F|
#|  2|   [E, F, G]|  2|  G|
#|  3|      [H, I]|  0|  H|
#|  3|      [H, I]|  1|  I|
#|  4|         [J]|  0|  J|
#+---+------------+---+---+

Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr which allows us use column values as parameters.

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .show()
#+---+-------+---+
#|num|   name|val|
#+---+-------+---+
#|  1|letter0|  A|
#|  1|letter1|  B|
#|  1|letter2|  C|
#|  1|letter3|  D|
#|  2|letter0|  E|
#|  2|letter1|  F|
#|  2|letter2|  G|
#|  3|letter0|  H|
#|  3|letter1|  I|
#|  4|letter0|  J|
#+---+-------+---+

Now we can just groupBy the num and pivot the DataFrame. Putting that all together, we get:

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .groupBy("num").pivot("name").agg(f.first("val"))\
    .show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#|  1|      A|      B|      C|      D|
#|  3|      H|      I|   null|   null|
#|  2|      E|      F|      G|   null|
#|  4|      J|   null|   null|   null|
#+---+-------+-------+-------+-------+

you have the print_r function DOC

Another way for filtering the database with specific word.

SHOW DATABASES WHERE `Database` LIKE '<yourDatabasePrefixHere>%'
or
SHOW DATABASES LIKE '<yourDatabasePrefixHere>%';

Example:

SHOW DATABASES WHERE `Database` LIKE 'foobar%'
foobar_animal
foobar_humans_gender
foobar_objects

I have solved a similar problem using external native lib dependencies that are packaged inside of jar files. Sometimes these architecture dependend libraries are packaged alltogether inside one jar, sometimes they are split up into several jar files. so i wrote some buildscript to scan the jar dependencies for native libs and sort them into the correct android lib folders. Additionally this also provides a way to download dependencies that not found in maven repos which is currently usefull to get JNA working on android because not all native jars are published in public maven repos.

Right from my experience, I most often get this when I have locally changed files that will be over ridden by the pull, you need to stash or move the files before you can pull it.

I had the same error on OSX Sierra, but in my case the ~/.android folder was owned by root (from a previous install) I changed the ownership to my User and now it works.

You most likely get this message when the project points to an old location of the assembly where it no longer exists. Since you were able to build it once, the assembly has already been copied into your bin\Debug / bin\Release folders so your project can still find a copy.

If you open the references node of the project in your solution explorer, there should be a yellow icon next to the reference. Remove the reference and add it again from the correct location.

If you want to know the location it was referenced from, you'd have to open the .csproj file in a text editor and look for the HintPath for that assembly - the IDE for some reason does not show this information.

There's an alternative to the StopIteration by using next(iterator, default_value).

For exapmle:

>>> a = iter('hi')
>>> print next(a, None)
h
>>> print next(a, None)
i
>>> print next(a, None)
None

So you can detect for None or other pre-specified value for end of the iterator if you don't want the exception way.

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

The quickest solution to your problem I believe is that you simply are missing parentheses on your getText. Simply add () to edit.getText().toString() and that should solve it

If the commit you want to revert is a merged commit (has been merged already), then you should either -m 1 or -m 2 option as shown below. This will let git know which parent commit of the merged commit to use. More details can be found HERE.

• git revert <commit> -m 1
• git revert <commit> -m 2

You can simply write:

val mutableList = mutableListOf<Kolory>()

This is the most idiomatic way.

Alternative ways are

val mutableList : MutableList<Kolory> = arrayListOf()

or

val mutableList : MutableList<Kolory> = ArrayList()

This is exploiting the fact that java types like ArrayList are implicitly implementing the type MutableList via a compiler trick.

This works for me

dataGridView1.Rows[rowIndex].Cells[columnIndex].Style.BackColor = Color.Red;

This should work you.

Running composer dump-autoload solves it for me.

Authentication is done via a simple ldap_bind command that takes the users DN and the password. The user is authenticated when the bind is successfull. Usually you would get the users DN via an ldap_search based on the users uid or email-address.

Getting the users roles is something different as it is an ldap_search and depends on where and how the roles are stored in the ldap. But you might be able to retrieve the roles during the lap_search used to find the users DN.

AlexRobbins' answer worked for me, except that the first two lines need to be in the model (perhaps this was assumed?), and should reference self:

def book_author(self):
  return self.book.author

Then the admin part works nicely.

Download the source package, open Terminal.app, navigate to the directory where you currently have the file, and then execute:

R CMD INSTALL RJSONIO_0.2-3.tar.gz

Do note that this will only succeed when either: a) the package does not need compilation or b) the needed system tools for compilation are present. See: https://cran.r-project.org/bin/macosx/tools/

Just an important note. If you have HTML comment and your uncomment doesn't work
(Maybe it's a PHP file), so don't mark all the comment but just put your cursor at the end or at the beginning of the comment (before ) and try again (Ctrl+/).

You can try using Seaborn. It works for both 2.7 as well as 3.6. You can install it by running:

pip install seaborn

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

According to my experience in most cases loops have the "main" condition to continue. This is the condition that should be written into while() operator itself. All other conditions that may break the loop are secondary, not so important etc. They can be written as additional if() {break} statements.

while(true) is often confusing and is less readable.

I think that these rules do not cover 100% of cases but probably only 98% of them.

This is what I use, based on this link

Start Powershell as administrator and run:

net start [MySQL-service-name]

Find the service name:

run 'services.msc', look for MySQL and click on properties

Another way

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")

Also, if you keep a list of values in, say A1 to A3, then you can use

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")

The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.

As of Notepad++ 6.9, the new Folder as Workspace feature can be used.

Folder as Workspace opens your folder(s) in a panel so you can browse folder(s) and open any file in Notepad++. Every changement in the folder(s) from outside will be synchronized in the panel. Usage: Simply drop 1 (or more) folder(s) in Notepad++.

This feature has the advantage of not showing your entire file system when just the working directory is needed. It also means you don't need plugins for it to work.

Use this instead:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked') //...
});

Let me explain you what the selector does: input[type="checkbox"] means that this will match each <input /> with type attribute type equals to checkbox After that: :checked will match all checked checkboxes.

You can loop over these checkboxes with:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked').each(function () {
       //this is the current checkbox
    });
});

Here is demo in JSFiddle.

And here is a demo which solves exactly your problem http://jsfiddle.net/DuE8K/1/.

$('#save').click(function () {
    $('#mytable').find('tr').each(function () {
        var row = $(this);
        if (row.find('input[type="checkbox"]').is(':checked') &&
            row.find('textarea').val().length <= 0) {
            alert('You must fill the text area!');
        }
    });
});

This one works for me.

`Post.find().sort({postedon: -1}).find(function (err, sortedposts){
    if (err) 
        return res.status(500).send({ message: "No Posts." });
    res.status(200).send({sortedposts : sortedposts});
 });`

The original frameset model (Frameset and Frame-elements) were very bad from a usability standpoint. IFrame vas a later invention which didn't have as many problems as the original frameset model, but it does have its drawback.

If you allow the user to navigate inside the IFrame, then links and bookmarks will not work as expected (because you bookmark the URL of the outer page, but not the URL of the iframe).

1. Make sure password authentication is enabled on the target server. If it runs Ubuntu, then open /etc/ssh/sshd_config on the server, find lines PasswordAuthentication=no and comment all them out (put # at the start of the line), save the file and run sudo systemctl restart ssh to apply the configuration. If there is no such line then you're done.
2. Add -o PreferredAuthentications="password" to your scp command, e.g.:

   scp -o PreferredAuthentications="password" /path/to/file user@server:/destination/directory
   

In addition to Daniel Howard's answer, here is what new does (or at least seems to do):

function New(func) {
    var res = {};
    if (func.prototype !== null) {
        res.__proto__ = func.prototype;
    }
    var ret = func.apply(res, Array.prototype.slice.call(arguments, 1));
    if ((typeof ret === "object" || typeof ret === "function") && ret !== null) {
        return ret;
    }
    return res;
}

While

var obj = New(A, 1, 2);

is equivalent to

var obj = new A(1, 2);

Try this:

-- http://lua-users.org/wiki/FileInputOutput

-- see if the file exists
function file_exists(file)
  local f = io.open(file, "rb")
  if f then f:close() end
  return f ~= nil
end

-- get all lines from a file, returns an empty 
-- list/table if the file does not exist
function lines_from(file)
  if not file_exists(file) then return {} end
  lines = {}
  for line in io.lines(file) do 
    lines[#lines + 1] = line
  end
  return lines
end

-- tests the functions above
local file = 'test.lua'
local lines = lines_from(file)

-- print all line numbers and their contents
for k,v in pairs(lines) do
  print('line[' .. k .. ']', v)
end

I yoinked this from the chosen library: https://github.com/harvesthq/chosen/blob/master/coffee/chosen.jquery.coffee

function preventParentScroll(evt) {
    var delta = evt.deltaY || -evt.wheelDelta || (evt && evt.detail)
    if (delta) {
        evt.preventDefault()
        if (evt.type ==  'DOMMouseScroll') {
            delta = delta * 40  
        }
        fakeTable.scrollTop = delta + fakeTable.scrollTop
    }
}
var el = document.getElementById('some-id')
el.addEventListener('mousewheel', preventParentScroll)
el.addEventListener('DOMMouseScroll', preventParentScroll)

This works for me.

Just set in XAML:

        <TextBox IsReadOnly="True" Style="{x:Null}" />

So that text will not be grayed-out.

When starting all over is not an option...

I deleted the log file in the .svn directory (I also deleted the offending file in .svn/props-base), did a cleanup, and resumed my update.

plt.rcParams['figure.figsize'] = (15, 5)

there is no way to specifically target an element with php, you can either embed the php code between a div tag or use jquery which would be longer.

_{I've used a mix of two howtos: Jason's and alex's. With the second we have the advantage of being able to debug. I'll mostly just copy both below (and simplify alex's):}

_{Update Jan 2012: this still works on SDK 4.2.1 and iOS 5.0.1 - I've just tested it all on a new computer and device!}

1. Create Self-Signed Certificate

Patch your iPhone SDK to allow the use of this certificate:

1. Launch Keychain Access.app. With no items selected, from the Keychain menu select Certificate Assistant, then Create a Certificate.

   • Name: iPhone Developer
   • Certificate Type: Code Signing
   • Let me override defaults: Yes

2. Click Continue

   • Validity: 3650 days

3. Click Continue

4. Blank out the Email address field.

5. Click Continue until complete.

   You should see "This root certificate is not trusted". This is expected.

6. Set the iPhone SDK to allow the self-signed certificate to be used:

   sudo /usr/bin/sed -i .bak 's/XCiPhoneOSCodeSignContext/XCCodeSignContext/' /Developer/Platforms/iPhoneOS.platform/Info.plist
   

   If you have Xcode open, restart it for this change to take effect.

And if you're on iOS 5, that's it! Try it now! It may not allow debugging, but the app will be there!

_{I was very surprised by this because, as you should know, I've got no idea on what all those hackings are all about! All I did was improving a little bit what I found elsewhere, as I pointed.}

_{So yeah, the whole method doesn't work the same way anymore and I couldn't bother to find a new one... Except for this, which uses a tool called Theos but I couldn't go through the whole process.}

_{Finally, if you need to uninstall it for whatever reason, check the end of this post. In my case, I had to because I couldn't figure out why all of the blue this whole method stopped working, and I couldn't care anymore since we've already got the long waited license. (Freaking DUNS number takes so long...)}

2. Enable Xcode's to Build on Jailbroken Device

1. On your jailbroken iPhone, install the app AppSync by adding source ** http://repo.hackyouriphone.org**

2. Remove SDK requirements for code sign and entitlements (I'm loving sed!):

   sudo /usr/bin/sed -i .bak '/_REQUIRED/N;s/YES/NO/' /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/SDKSettings.plist
   

3. Pay attention to the iPhoneOS5.0.sdk part. If you're, for instance, using iOS 4.2 SDK, just replace it accordingly:

   sudo /usr/bin/sed -i .bak '/_REQUIRED/N;s/YES/NO/' /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/SDKSettings.plist
   

4. Conclude the requirement removal through patching Xcode. This means binary editing:

   cd /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS\ Build\ System\ Support.xcplugin/Contents/MacOS/
   dd if=iPhoneOS\ Build\ System\ Support of=working bs=500 count=255
   printf "\xc3\x26\x00\x00" >> working
   /bin/mv -n iPhoneOS\ Build\ System\ Support iPhoneOS\ Build\ System\ Support.original
   /bin/mv working iPhoneOS\ Build\ System\ Support
   chmod a+x iPhoneOS\ Build\ System\ Support
   

   If you have Xcode open, restart it for this change (and last one) to take effect.

5. Open "Project>Edit Project Settings" (from the menu). Click on the "Build" tab. Find "Code Signing Identity" and its child "Any iPhoneOS Device" in the list, and set both to the entry "Don't Code Sign":

   

   After this feel free to undo step 3. At least in my case it went just fine.

6. Setting Xcode to code sign with our custom made self-signed certificate (the first how-to). This step can probably be skipped if you don't want to be able to debug:

   mkdir /Developer/iphoneentitlements401
   cd /Developer/iphoneentitlements401
   curl -O http://www.alexwhittemore.com/iphone/gen_entitlements.txt
   mv gen_entitlements.txt gen_entitlements.py
   chmod 777 gen_entitlements.py
   

   Plug your iPhone in and open Xcode. Open Window>Organizer. Select the device from the list on the left hand side, and click "Use for development." You'll be prompted for a provisioning website login, click cancel. It's there to make legitimate provisioning easier, but doesn't make illegitimate not-provisioning more difficult.

   Now You have to do this last part for every new project you make. Go to the menu Project > New Build Phase > New Run Script Build Phase. In the window, copy/paste this:

   export CODESIGN_ALLOCATE=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
   if [ "${PLATFORM_NAME}" == "iphoneos" ]; then
   /Developer/iphoneentitlements401/gen_entitlements.py "my.company.${PROJECT_NAME}" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
   codesign -f -s "iPhone Developer" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
   fi
   

.

.

.

.

Uninstalling

For the 1st part:

sudo mv -f /Developer/Platforms/iPhoneOS.platform/Info.plist.bak /Developer/Platforms/iPhoneOS.platform/Info.plist

For the 2nd part:

sudo mv -f /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/SDKSettings.plist.bak /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/SDKSettings.plist
sudo mv -f iPhoneOS\ Build\ System\ Support.original iPhoneOS\ Build\ System\ Support

in case you did do the step 3 instead of 2, simply modify it accordingly as well:

sudo mv -f /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/SDKSettings.plist.bak /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/SDKSettings.plist

for the rest, is just reverting what you did on XCode and deleting /Developer/iphoneentitlements401/gen_entitlements.py if you want:

sudo rm -f /Developer/iphoneentitlements401/gen_entitlements.py

I know it's a little late for an answer, but I've created a polyfill for the .live() method. I've tested it in jQuery 1.11, and it seems to work pretty well. I know that we're supposed to implement the .on() method wherever possible, but in big projects, where it's not possible to convert all .live() calls to the equivalent .on() calls for whatever reason, the following might work:

if(jQuery && !jQuery.fn.live) {
    jQuery.fn.live = function(evt, func) {
        $('body').on(evt, this.selector, func);
    }
}

Just include it after you load jQuery and before you call live().

This is fast & works for whatever length.

public static String prefixZeros(String value, int len) {
    char[] t = new char[len];
    int l = value.length();
    int k = len-l;
    for(int i=0;i<k;i++) { t[i]='0'; }
    value.getChars(0, l, t, k);
    return new String(t);
}

May be your Plesk panel or other panel subscription has been expired....please check subscription End.

The above could also be written with less code as:

new List<SomeType>(items).ForEach(
    i => Console.WriteLine(i)
);

This creates a generic list and populates it with the IEnumerable and then calls the list objects ForEach.

I'm using Anaconda on Windows 10, with a GTX 1660 Super. I first installed the CUDA environment following this step-by-step. However there is now a keras-gpu metapackage available on Anaconda which apparently doesn't require installing CUDA and cuDNN libraries beforehand (mine were already installed anyway).

This is what worked for me to create a dedicated environment named keras_gpu:

# need to downgrade from tensorflow 2.1 for my particular setup
conda create --name keras_gpu keras-gpu=2.3.1 tensorflow-gpu=2.0

To add on @johncasey 's answer but for TensorFlow 2.0, adding this block works for me:

import tensorflow as tf
from tensorflow.python.keras import backend as K

# adjust values to your needs
config = tf.compat.v1.ConfigProto( device_count = {'GPU': 1 , 'CPU': 8} )
sess = tf.compat.v1.Session(config=config) 
K.set_session(sess)

This post solved the set_session error I got: you need to use the keras backend from the tensorflow path instead of keras itself.

Does the child process have a pipe to/from the parent process? If so, you'd receive a SIGPIPE if writing, or get EOF when reading - these conditions could be detected.

            using (var tbl = new DataTable())
            using (var rdr = cmd.ExecuteReader())
            {
                tbl.BeginLoadData();

                try
                {
                    tbl.Load(rdr);
                }
                catch (ConstraintException ex)
                {
                    rdr.Close();
                    tbl.Clear();

                    // clear constraints, source of exceptions
                    // note: column schema already loaded!
                    tbl.Constraints.Clear();
                    tbl.Load(cmd.ExecuteReader());
                }
                finally
                {
                    tbl.EndLoadData();
                }
            }

the initial value of your data-backdrop attribute can be

"static","true", "false" .

static and true add the modal shadow, while false disable the shadow, so you just need to change this value with the first click to false . like this:

$(document).on('ready',function(){_x000D_
 _x000D_
 var count=0;_x000D_
 _x000D_
$('#id-which-triggers-modal').on('click',function(){_x000D_
  _x000D_
  if(count>0){_x000D_
  _x000D_
   $(this).attr('data-backdrop','false')_x000D_
  }_x000D_
  count++;_x000D_
});_x000D_
_x000D_
_x000D_
});

you can use this trick to run tomcat using cmd and directly by tomcat bin folder.

1. set the path of jdk.

2.

To set path. go to Desktop and right click on computer icon. Click the Properties

go to Advance System Settings.

then Click Advance to Environment variables.

Click new and set path AS,

in the column Variable name=JAVA_HOME

Variable Value=C:\Program Files\Java\jdk1.6.0_19

Click ok ok.

now path is stetted.

3.

Go to tomcat folder where you installed the tomcat. go to bin folder. there are two window batch files.

1.Startup

2.Shutdown.

By using cmd if you installed the tomcate in D Drive

type on cmd screen

1. D:

2. Cd tomcat\bin then type Startup.

4. By clicking them you can start and stop the tomcat.

5.

Final step.

if you start and want to check it.

open a Browser in URL bar type.

Had the same problem. I used dotenv-webpack and need to define

plugins: [
  new Dotenv()
]

in both webpack production and webpack base files (I use webpack merge). If was not defined in both files then it did not work.

Try this:

@echo off
setlocal
cd /d %~dp0
Call :UnZipFile "C:\Temp\" "c:\path\to\batch.zip"
exit /b

:UnZipFile <ExtractTo> <newzipfile>
set vbs="%temp%\_.vbs"
if exist %vbs% del /f /q %vbs%
>%vbs%  echo Set fso = CreateObject("Scripting.FileSystemObject")
>>%vbs% echo If NOT fso.FolderExists(%1) Then
>>%vbs% echo fso.CreateFolder(%1)
>>%vbs% echo End If
>>%vbs% echo set objShell = CreateObject("Shell.Application")
>>%vbs% echo set FilesInZip=objShell.NameSpace(%2).items
>>%vbs% echo objShell.NameSpace(%1).CopyHere(FilesInZip)
>>%vbs% echo Set fso = Nothing
>>%vbs% echo Set objShell = Nothing
cscript //nologo %vbs%
if exist %vbs% del /f /q %vbs%

Revision

To have it perform the unzip on each zip file creating a folder for each use:

@echo off
setlocal
cd /d %~dp0
for %%a in (*.zip) do (
    Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa"
)
exit /b

If you don't want it to create a folder for each zip, change Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa" to Call :UnZipFile "C:\Temp\" "c:\path\to\%%~nxa"

To get back to the parent frame, use:

driver.switchTo().parentFrame();

To get back to the first/main frame, use:

driver.switchTo().defaultContent();

Here is tool for lazy coders:

1 add dependency:

compile 'com.vk:androidsdk:1.6.9'

2 add following lines somewhere in your activity/application:

String[] fingerprints = VKUtil.getCertificateFingerprint(this, getPackageName()); 
Log.d("SHA1", fingerprints[0]);

3 Open logcat and catch message.

4 Profit!

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

There are also the %<% and %<=% comparison operators in the TeachingDemos package which allow you to do this like:

sum( 2 %<% x %<% 5 )
sum( 2 %<=% x %<=% 5 )

which gives the same results as:

sum( 2 < x & x < 5 )
sum( 2 <= x & x <= 5 )

Which is better is probably more a matter of personal preference.

Rails provides a solution to this: shallow nesting.

I think this is a good because when you deal directly with a known resource, there's no need to use nested routes, as has been discussed in other answers here.

What worked for me was to create a new report from scratch.

This done and the new report working, I will compare the 2 .rdl files in Visual Studio. These are in XML format and I am hoping a quick WindDiff or something would reveal what the issue was.

An initial look shows there are 700 lines of code or a bit more difference between both files, with the larger of the 2 being the faulty file. A cursory look at the TablixHeader tags didn't reveal anything obvious.

But in my case it was a corrupted .rdl file. This was originally copied from a working report so in the process of removing what wasn't re-used, this could have corrupted it. However, other reports where this same process was done, the headers could repeat when the correct settings were made in Properties.

Hope this helps. If you've got a complex report, this isn't the quick fix but it works.

Perhaps comparing known good XML files to faulty ones on your end would make a good forum post. I'll be trying that on my end.

As stated in the JQuery documentation

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

In-line:

while true; do <your-bash-snippet> && break; done

e.g.

while true; do openconnect x.x.x.x:xxxx && break; done

yum list installed | grep mysql

Then if it's not installed you can do (as root)

yum install mysql -y

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

You need to check for DBNull, not null. Additionally, two of your three ReplaceNull methods don't make sense. double and DateTime are non-nullable, so checking them for null will always be false...

Joining on multiple columns in Linq to SQL is a little different.

var query =
    from t1 in myTABLE1List // List<TABLE_1>
    join t2 in myTABLE1List
      on new { t1.ColumnA, t1.ColumnB } equals new { t2.ColumnA, t2.ColumnB }
    ...

You have to take advantage of anonymous types and compose a type for the multiple columns you wish to compare against.

This seems confusing at first but once you get acquainted with the way the SQL is composed from the expressions it will make a lot more sense, under the covers this will generate the type of join you are looking for.

EDIT Adding example for second join based on comment.

var query =
    from t1 in myTABLE1List // List<TABLE_1>
    join t2 in myTABLE1List
      on new { A = t1.ColumnA, B = t1.ColumnB } equals new { A = t2.ColumnA, B = t2.ColumnB }
    join t3 in myTABLE1List
      on new { A = t2.ColumnA, B =  t2.ColumnB } equals new { A = t3.ColumnA, B = t3.ColumnB }
    ...

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

get returns Collection and is rather supposed to fetch multiple rows.

count is a generic way of checking the result:

$user = User::where(...)->first(); // returns Model or null
if (count($user)) // do what you want with $user

// or use this:
$user = User::where(...)->firstOrFail(); // returns Model or throws ModelNotFoundException

// count will works with a collection of course:
$users = User::where(...)->get(); // returns Collection always (might be empty)
if (count($users)) // do what you want with $users

objdump -T *.so may also do the job
