Programs & Examples On #Content length

Okay, this option is pretty hackish but should work.

$(document).ready( function() {
$('#select').change( function() {
    $('#hiddenDiv').html( $('#select').val() );
    $('#select').width( $('#hiddenDiv').width() );
 }
 }

Which would offcourse require a hidden div.

<div id="hiddenDiv" style="visibility:hidden"></div>

ohh and you will need jQuery

Try:

if(!$('#car2').is(':visible'))
{  
    alert('car 2 is hidden');       
}

I think I found it. All you have to do is type in "`n" (WITH THE QUOTATION MARKS!)

Thanks!

First I need to say that your code,

MyClass *myclass;
myclass->DoSomething();

will cause an undefined behavior. Because the pointer "myclass" isn't pointing to any "MyClass" type objects.

Here I have three suggestions for you:-

option 1:- You can simply declare and use a MyClass type object on the stack as below.

MyClass myclass; //allocates memory for the object "myclass", on the stack.
myclass.DoSomething();

option 2:- By using the new operator.

MyClass *myclass = new MyClass();

Three things will hapen here.

i) Allocates memory for the "MyClass" type object on the heap.

ii) Allocates memory for the "MyClass" type pointer "myclass" on the stack.

iii) pointer "myclass" points to the memory address of "MyClass" type object on the heap

Now you can use the pointer to access member functions of the object after dereferencing the pointer by "->"

myclass->DoSomething();

But you should free the memory allocated to "MyClass" type object on the heap, before returning from the scope unless you want it to exists. Otherwise it will cause a memory leak!

delete myclass; // free the memory pointed by the pointer "myclass"

option 3:- you can also do as below.

MyClass myclass; // allocates memory for the "MyClass" type object on the stack.
MyClass *myclassPtr; // allocates memory for the "MyClass" type pointer on the stack.
myclassPtr = &myclass; // "myclassPtr" pointer points to the momory address of myclass object.

Now, pointer and object both are on the stack. Now you can't return this pointer to the outside of the current scope because both allocated memory of the pointer and the object will be freed while stepping outside the scope.

So as a summary, option 1 and 3 will allocate an object on the stack while only the option 2 will do it on the heap.

There are a couple of potential problems with this approach, though in a lot of circumstances (such as your example) it will work well.

In particular you should be careful when dealing with anything that deals with the GUI that requires a Context. For example, if you pass the application Context into the LayoutInflater you will get an Exception. Generally speaking, your approach is excellent: it's good practice to use an Activity's Context within that Activity, and the Application Context when passing a context beyond the scope of an Activity to avoid memory leaks.

Also, as an alternative to your pattern you can use the shortcut of calling getApplicationContext() on a Context object (such as an Activity) to get the Application Context.

A simple but dirty trick is to simply add the offset you want to the image you are using as background. it's not maintainable, but it gets the job done.

Jarrett's answer creates a new table.

Scott's answer inserts into an existing table with the same structure.

You can also insert into a table with different structure:

INSERT Table2
(columnX, columnY)
SELECT column1, column2 FROM Table1
WHERE [Conditions]

Since the code you've provided does not explicitly include anything, either it is being incldued twice, or (if the script is the entry point for the code) there must be a auto-prepend set up in the webserver config / php.ini or alternatively you've got a really obscure extension loaded which defines the function.

What worked for me was stopping the Internet Information Services (IIS). If you are using Windows 7, click on your Start button and in your search box, type "iis". Click on "Internet Information Services (IIS) Manager". When the window pops up, and assuming you've got none of the icons selected, you should just be able to click Stop on the right action pane. My XAMPP Apache started right up. Hope it all worked out for you.

The basic steps are:

1. Use a custom authentication provider

   <bean id="myAuthenticationProvider" class="myProviderImplementation" scope="singleton">
   ...
   </bean>
   

2. Make your custom provider return a custom UserDetails implementation. This UserDetailsImpl will have a getAuthorities() like this:

   public Collection<GrantedAuthority> getAuthorities() {
       List<GrantedAuthority> permissions = new ArrayList<GrantedAuthority>();
       for (GrantedAuthority role: roles) {
           permissions.addAll(getPermissionsIncludedInRole(role));
       }
       return permissions;
   }
   

Of course from here you could apply a lot of optimizations/customizations for your specific requirements.

edit

Could you try the correct type for your script tags? I see you use text/Scripts, which is not the right mimetype for javascript.

Use this:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> 
<script type="text/javascript" src="../Scripts/jquery.dropdownPlain.js"></script>
<script type="text/javascript" src="../Scripts/facebox.js"></script>

end edit

or you could take a look at require.js which is a loader for your javascript code.

depending on your project, this could however be a bit overkill

If you have this problem in Windows 10, and you know you have premisions on folder (You could write before but it just started to print exception PermissionError recently).. You will need to install Windows updates... I hope someone will help this info.

As for the code example in the question, the standard solution is to reference the class explicitly by its name, and it is even possible to do without getClassLoader() call:

class MyClass {
  public static void startMusic() {
    URL songPath = MyClass.class.getResource("background.midi");
  }
}

This approach still has a back side that it is not very safe against copy/paste errors in case you need to replicate this code to a number of similar classes.

And as for the exact question in the headline, there is a trick posted in the adjacent thread:

Class currentClass = new Object() { }.getClass().getEnclosingClass();

It uses a nested anonymous Object subclass to get hold of the execution context. This trick has a benefit of being copy/paste safe...

Caution when using this in a Base Class that other classes inherit from:

It is also worth noting that if this snippet is shaped as a static method of some base class then currentClass value will always be a reference to that base class rather than to any subclass that may be using that method.

Think this way:

Spring MVC is a web based framework to implement the MVC architecture.

Spring Boot is a tool oriented to the programmer. Programmer must focus on programming and tool must focus on configurations. So we don't need to wast our time configuring a bunch of xml to make a simple 'Hello world'.

This only happens when you use the dev-tools, and won't happen for normal users accessing the production server.

In any case, I found it useful to simply disable this behavior in the dev-tools: open the settings and uncheck the "Enable source maps" option.

There will no longer be an attempt to access map files.

Resolved with the following solution

1. Right click on the edmx file, select Open with, XML editor
2. Locate the entity in the edmx:StorageModels element
3. Remove the DefiningQuery entirely
4. Rename the store:Schema="dbo" to Schema="dbo" (if exists)
5. Remove the store:Name property

I suppose that

std::to_string(i)

could do the job, it's an overloaded function, it could be any numeric type such as int, double or float

Kotlin version would be

fun getHeaderInterceptor():Interceptor{
    return object : Interceptor {
        @Throws(IOException::class)
        override fun intercept(chain: Interceptor.Chain): Response {
            val request =
            chain.request().newBuilder()
                    .header(Headers.KEY_AUTHORIZATION, "Bearer.....")
                    .build()
            return chain.proceed(request)
        }
    }
}


private fun createOkHttpClient(): OkHttpClient {
    return OkHttpClient.Builder()
            .apply {
                if(BuildConfig.DEBUG){
                    this.addInterceptor(HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BASIC))
                }
            }
            .addInterceptor(getHeaderInterceptor())
            .build()
}

fwrite() is a smidgen faster and file_put_contents() is just a wrapper around those three methods anyway, so you would lose the overhead. Article

file_put_contents(file,data,mode,context):

The file_put_contents writes a string to a file.

This function follows these rules when accessing a file.If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename Create the file if it does not exist then Open the file and Lock the file if LOCK_EX is set and If FILE_APPEND is set, move to the end of the file. Otherwise, clear the file content Write the data into the file and Close the file and release any locks. This function returns the number of the character written into the file on success, or FALSE on failure.

fwrite(file,string,length):

The fwrite writes to an open file.The function will stop at the end of the file or when it reaches the specified length, whichever comes first.This function returns the number of bytes written or FALSE on failure.

Since this issue is kind of old a lot of things have changed.

You can now get this behavior by adding this to the footer div

data-position="fixed"

More info here: http://jquerymobile.com/test/docs/toolbars/bars-fixed.html

Also beware, if you use the previously mentioned CSS together with the new JQM solution you will NOT get the appropriate behavior!

You need to convert the date time object to a string.

The following code worked for me:

import datetime
collection = []
dateTimeString = str(datetime.date.today())
collection.append(dateTimeString)
print collection

Let me know if you need any more help.

Try moving the lapsList function out of your class and into your render function:

render() {
  const lapsList = this.state.laps.map((data) => {
    return (
      <View><Text>{data.time}</Text></View>
    )
  })

  return (
    <View style={styles.container}>
      <View style={styles.footer}>
        <View><Text>coucou test</Text></View>
        {lapsList}
      </View>
    </View>
  )
}

This is for Color to Brush....

you can't convert it, you have to make a new brush....

SolidColorBrush brush = new SolidColorBrush( myColor );

now, if you need it in XAML, you COULD make a custom value converter and use that in a binding

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

This issue could by happen while using unmanaged oracle reference if you have more than one oracle client , or sometimes if you reference different version
There is two way to solve it :

1. First and fast solution is to remove unmanaged reference and use the managed one from NuGet see this before to go with this option Differences between the ODP.NET Managed Driver and Unmanaged Driver

2. Second solution is to fix project unmanaged target version like the below :

• First Check oracle project reference version (from project references/(dependencies > assemblies ) > Oracle.DataAccess right click > properties):
  
  
  
  

Then check oracle GAC version

• got to gac from run (Win+R) "%windir%\Microsoft.NET\assembly"
  

• Check the platform that matches with you project platform
  
  

• to check you target platform (right click on your project > properties)
  
  

• From gac folder search to Oracle.DataAccess
  
  

• Right Click on Oracle.DataAccess > properties > details and check version
  
  

• if you notice the versions are different this is an the issue and to fix it we need to redirect assembly version (in startup project go to config file and add the below section )

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89b483f429c47342" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.121.2.0" />
      </dependentAssembly>
</assemblyBinding>

like this

oldVersion : should be cover your project version newVersion : GAC version publicKeyToken : From GAC

So, using IntelliJ with Android (Studio) plugin was: I went to AndroidManifest.xml on top and changed package name by right-clicking -> Refactor -> rename. Our then package name had four parts a.b.c.d, the new one only a.b.c. So I renamed the first three. Then I went to the directory of generated sources (app\build\generated\source\r\development\debug\a\b\c\d), right-clicked R class and Refactor->Move[d] it to one package higher. Same with BuildConfig in app\build\generated\source\buildConfig\development\debug\a\b\c\d.

By using Refactor->Move, IntelliJ updates all references to BuildConfig and R.

Finally I updated all applicationId[s] I found in gradle.build I found. I hit Clean Project, Make and Rebuild Project. Deleted the app from my phone and hit "Play". It all worked out so refactoring was easy and quite fast.

Try This

    final Button button = (Button) findViewById(R.id.button_id);
    button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View view, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP) {
                button.setBackgroundColor(Color.RED);
            } else if(event.getAction() == MotionEvent.ACTION_DOWN) {
                button.setBackgroundColor(Color.BLUE);
            }
            return false;
        }

    });

Another scenario where this shows up is if you are using the older "Web Site" project type in Visual Studio. For that project type, it is unable to reference .dlls that are outside of it's own directory structure (current folder and down). So in the answer above, let's say your directory structure looks like this:

Where ProjectX and ProjectY are parent/child directories, and ProjectX references A.dll which in turn references B.dll, and B.dll is outside the directory structure, such as in a Nuget package on the root (Packages), then A.dll will be included, but B.dll will not.

This has a simple method using SendKeys to unprotect the VBA project. This would get you into the project, so you'd have to continue on using SendKeys to figure out a way to remove the password protection: http://www.pcreview.co.uk/forums/thread-989191.php

And here's one that uses a more advanced, somewhat more reliable method for unprotecting. Again, it will only unlock the VB project for you. http://www.ozgrid.com/forum/showthread.php?t=13006&page=2

I haven't tried either method, but this may save you some time if it's what you need to do...

connect timeout has to be handled with a non-blocking socket (GNU LibC documentation on connect). You get connect to return immediately and then use select to wait with a timeout for the connection to complete.

This is also explained here : Operation now in progress error on connect( function) error.

int wait_on_sock(int sock, long timeout, int r, int w)
{
    struct timeval tv = {0,0};
    fd_set fdset;
    fd_set *rfds, *wfds;
    int n, so_error;
    unsigned so_len;

    FD_ZERO (&fdset);
    FD_SET  (sock, &fdset);
    tv.tv_sec = timeout;
    tv.tv_usec = 0;

    TRACES ("wait in progress tv={%ld,%ld} ...\n",
            tv.tv_sec, tv.tv_usec);

    if (r) rfds = &fdset; else rfds = NULL;
    if (w) wfds = &fdset; else wfds = NULL;

    TEMP_FAILURE_RETRY (n = select (sock+1, rfds, wfds, NULL, &tv));
    switch (n) {
    case 0:
        ERROR ("wait timed out\n");
        return -errno;
    case -1:
        ERROR_SYS ("error during wait\n");
        return -errno;
    default:
        // select tell us that sock is ready, test it
        so_len = sizeof(so_error);
        so_error = 0;
        getsockopt (sock, SOL_SOCKET, SO_ERROR, &so_error, &so_len);
        if (so_error == 0)
            return 0;
        errno = so_error;
        ERROR_SYS ("wait failed\n");
        return -errno;
    }
}

To my knowledge, you can't mock constructors with mockito, only methods. But according to the wiki on the Mockito google code page there is a way to mock the constructor behavior by creating a method in your class which return a new instance of that class. then you can mock out that method. Below is an excerpt directly from the Mockito wiki:

Pattern 1 - using one-line methods for object creation

To use pattern 1 (testing a class called MyClass), you would replace a call like

   Foo foo = new Foo( a, b, c );

with

   Foo foo = makeFoo( a, b, c );

and write a one-line method

   Foo makeFoo( A a, B b, C c ) { 
        return new Foo( a, b, c );
   }

It's important that you don't include any logic in the method; just the one line that creates the object. The reason for this is that the method itself is never going to be unit tested.

When you come to test the class, the object that you test will actually be a Mockito spy, with this method overridden, to return a mock. What you're testing is therefore not the class itself, but a very slightly modified version of it.

Your test class might contain members like

  @Mock private Foo mockFoo;
  private MyClass toTest = spy(new MyClass());

Lastly, inside your test method you mock out the call to makeFoo with a line like

  doReturn( mockFoo )
      .when( toTest )
      .makeFoo( any( A.class ), any( B.class ), any( C.class ));

You can use matchers that are more specific than any() if you want to check the arguments that are passed to the constructor.

If you're just wanting to return a mocked object of your class I think this should work for you. In any case you can read more about mocking object creation here:

http://code.google.com/p/mockito/wiki/MockingObjectCreation

I know this is an old Question

But in case you want to do it programmatically or the java way

For Image Backgrounds; you can use BackgroundImage class

BackgroundImage myBI= new BackgroundImage(new Image("my url",32,32,false,true),
        BackgroundRepeat.REPEAT, BackgroundRepeat.NO_REPEAT, BackgroundPosition.DEFAULT,
          BackgroundSize.DEFAULT);
//then you set to your node
myContainer.setBackground(new Background(myBI));

For Paint or Fill Backgrounds; you can use BackgroundFill class

BackgroundFill myBF = new BackgroundFill(Color.BLUEVIOLET, new CornerRadii(1),
         new Insets(0.0,0.0,0.0,0.0));// or null for the padding
//then you set to your node or container or layout
myContainer.setBackground(new Background(myBF));

Keeps your java alive && your css dead..

Even though the answer from @dzuc is already very good, you could use array destructuring (available in modern browsers or with Babel) to make it even a bit more elegant:

// original version from @dzuc
const data = Array.from(formData.entries())
  .reduce((memo, pair) => ({
    ...memo,
    [pair[0]: pair[1],
  }), {})

// with array destructuring
const data = Array.from(formData.entries())
  .reduce((memo,[key, value]) => ({
    ...memo,
    [key]: value,
  }), {})

If you are using a JAX-WS implementation for your client, such as Metro Web Services, the following code shows how to pass username and password in the HTTP headers:

 MyService port = new MyService();
 MyServiceWS service = port.getMyServicePort();

 Map<String, List<String>> credentials = new HashMap<String,List<String>>();

 credentials.put("username", Collections.singletonList("username"));
 credentials.put("password", Collections.singletonList("password"));

 ((BindingProvider)service).getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, credentials);

Then subsequent calls to the service will be authenticated. Beware that the password is only encoded using Base64, so I encourage you to use other additional mechanism like client certificates to increase security.

The DoEvents does allow the user to click around or type and trigger other events, and background threads are a better approach.

However, there are still cases where you may run into issues that require flushing event messages. I ran into a problem where the RichTextBox control was ignoring the ScrollToCaret() method when the control had messages in queue to process.

The following code blocks all user input while executing DoEvents:

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace Integrative.Desktop.Common
{
    static class NativeMethods
    {
        #region Block input

        [DllImport("user32.dll", EntryPoint = "BlockInput")]
        [return: MarshalAs(UnmanagedType.Bool)]
        private static extern bool BlockInput([MarshalAs(UnmanagedType.Bool)] bool fBlockIt);

        public static void HoldUser()
        {
            BlockInput(true);
        }

        public static void ReleaseUser()
        {
            BlockInput(false);
        }

        public static void DoEventsBlockingInput()
        {
            HoldUser();
            Application.DoEvents();
            ReleaseUser();
        }

        #endregion
    }
}

I solved the problem REF

Run

# For Yarn
yarn add eslint-plugin-jest -D

# For NPM
npm i eslint-plugin-jest -D

And then add in your .eslintrc file

{
    "extends": ["airbnb","plugin:jest/recommended"],
}

I had same problem.

With RedirectAttributes after refreshing page, my model attributes from first controller have been lost. I was thinking that is a bug, but then i found solution. In first controller I add attributes in ModelMap and do this instead of "redirect":

return "forward:/nameOfView";

This will redirect to your another controller and also keep model attributes from first one.

I hope this is what are you looking for. Sorry for my English

I know this is an old thread but I was digging into the jQuery UI source code and built upon Rowan's answer which was closer to what I had been looking for. Only I needed the carrots as I felt it was important to have a visual indicator of possible submenus. From looking at the source code (both .js and .css) I came up with this that allows the carrot be visiable without messing with design (height) and also alowing menu to appear vertical below the parent item.

In the jquery-ui.js do a search to find $.widget( "ui.menu") and change postition to:

position: {
my: "center top",
at: "center bottom"
}

And in your css add:

#nav > .ui-menu:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

#nav > .ui-menu > .ui-menu-item {
    display: inline-block;
    float: left;

    margin: 0;
    padding: 3px;

    width: auto;
}

.ui-menu .ui-menu-item a {
    padding: 0;
}

.ui-menu .ui-menu-icon{
    position: relative;
    left: 1px;
    top: 6px;
}

End Result will be a jQuery UI Menu horizontal with sub menus being displayed veriticaly below the parent menu item.

Box shadows can use commas to have multiple effects, just like with background images (in CSS3).

Sorry for comment in an old post but if you want to use an else if statement this will help you

{% if title == source %}
    Do This
{% elif title == value %}
    Do This
{% else %}
    Do This
{% endif %}

This code explains the use of the ~tilda character, which was the most confusing thing to me. Once I understood this, it makes things much easier to understand:

@ECHO off
SET "PATH=%~dp0;%PATH%"
ECHO %PATH%
ECHO.
CALL :testargs "these are days" "when the brave endure"
GOTO :pauseit
:testargs
SET ARGS=%~1;%~2;%1;%2
ECHO %ARGS%
ECHO.
exit /B 0
:pauseit
pause

Wells are dropped from Bootstrap with the version 4.

You can use Cards instead of Wells.

Here is a quick example for how to use new Cards feature:

<div class="card card-inverse" style="background-color: #333; border-color: #333;">
  <div class="card-block">
    <h3 class="card-title">Card Title</h3>
    <p class="card-text">This text will be written on a grey background inside a Card.</p>
    <a href="#" class="btn btn-primary">This is a Button</a>
  </div>
</div>

Try this it will work, it's better create a procedure, if procedure is not possible you can use this script.

with param AS(
SELECT 1234 empid
FROM dual)
 SELECT *
  FROM Employees, param
  WHERE EmployeeID = param.empid;
END;

You have a selector ul on line 252 which is setting list-style: square outside none (a square bullet). You'll have to change it to list-style: none or just remove the line.

If you only want to remove the bullets from that specific instance, you can use the specific selector for that list and its items as follows:

ul#groups-list.items-list { list-style: none }

In simple term,

• "" is an empty String

• null is an empty String Variable.

As per the title of the post I just needed to get all values from a specific column. Here is the code I used to achieve that.

    public static IEnumerable<T> ColumnValues<T>(this DataColumn self)
    {
        return self.Table.Select().Select(dr => (T)Convert.ChangeType(dr[self], typeof(T)));
    }

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {

You should be able to use

IIF(Fields!ExitReason.Value = 7, 1, 0)

http://msdn.microsoft.com/en-us/library/ms157328.aspx

it could be a problem with your specific network adapter. I have a Dell 15R and there are no working drivers for ubuntu or ubuntu server; I even tried compiling wireless drivers myself, but to no avail.

However, in virtualbox, I was able to get wireless working by using the default configuration. It automatically bridged my internal wireless adapter and hence used my native OS's wireless connection for wireless.

If you are trying to get a separate wireless connection from within ubuntu in virtualbox, then it would take more configuring. If so, let me know, if not, I will not bother typing up instructions to something you are not looking to do, as it is quite complicated in some instances.

p.s. you should be using Windows 7 if you have any technical inclination. Do you live under a rock? No offense intended.

This one works:

<input type="button" value="test" onclick="alert('hey'); alert('ho');" />

And this one too:

function Hey()
{
    alert('hey');
}

function Ho()
{
    alert('ho');
}

.

<input type="button" value="test" onclick="Hey(); Ho();" />

So the answer is - yes you can :) However, I'd recommend to use unobtrusive JavaScript.. mixing js with HTML is just nasty.

I was having the same issue. So I went to the Java options through Control Panel. Copied the web address that I was having an issue with to the exceptions and it was fixed.

You can do this by installing the task while running as administrator via the TaskSchedler library. I'm making the assumption here that .NET/C# is a suitable platform/language given your related questions.

This library gives you granular access to the Task Scheduler API, so you can adjust settings that you cannot otherwise set via the command line by calling schtasks, such as the priority of the startup. Being a parental control application, you'll want it to have a startup priority of 0 (maximum), which schtasks will create by default a priority of 7.

Below is a code example of installing a properly configured startup task to run the desired application as administrator indefinitely at logon. This code will install a task for the very process that it's running from.

%matplotlib qt

If you got the error ImportError: Failed to import any qt binding then install PyQt5 as: pip install PyQt5 and it works for me.

just ran into the same problem and solved it with the following line of code:

selectize.addOption({text: "My Default Value", value: "My Default Value"});
selectize.setValue("My Default Value"); 

IsNullOrEmpty is essentially shorthand for the following:

return str == null || str == String.Empty;

So, no there is no function that just checks for nulls because it would be too simple. obj != null is the correct way. But you can create such a (superfluous) function yourself using the following extension:

public bool IsNull(this object obj)
{
    return obj == null;
}

Then you are able to run anyObject.IsNull().

There are so many difference exist between Serializable and Externalizable but when we compare difference between custom Serializable(overrided writeObject() & readObject()) and Externalizable then we find that custom implementation is tightly bind with ObjectOutputStream class where as in Externalizable case , we ourself provide an implementation of ObjectOutput which may be ObjectOutputStream class or it could be some other like org.apache.mina.filter.codec.serialization.ObjectSerializationOutputStream

In case of Externalizable interface

@Override
public void writeExternal(ObjectOutput out) throws IOException {
    out.writeUTF(key);
    out.writeUTF(value);
    out.writeObject(emp);
}

@Override
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
    this.key = in.readUTF();
    this.value = in.readUTF();
    this.emp = (Employee) in.readObject();
}





**In case of Serializable interface**


        /* 
             We can comment below two method and use default serialization process as well
             Sequence of class attributes in read and write methods MUST BE same.

            private void writeObject(java.io.ObjectOutputStream Outstream)
                    throws IOException {

                System.out.println("from writeObject()");
                /*     We can define custom validation or business rules inside read/write methods.

    called by JVM, immediately after default serialization 
    and deserialization process 
    happens.
                 checkTestInfo();
                */

                stream.writeUTF(name);
                stream.writeInt(age);
                stream.writeObject(salary);
                stream.writeObject(address);
            }

            private void readObject(java.io.ObjectInputStream Instream)
                    throws IOException, ClassNotFoundException {
                System.out.println("from readObject()");
                name = (String) stream.readUTF();
                age = stream.readInt();
                salary = (BigDecimal) stream.readObject();
                address = (Address) stream.readObject();
                // validateTestInfo();
            }

I have added sample code to explain better. please check in/out object case of Externalizable. These are not bound to any implementation directly.
Where as Outstream/Instream are tightly bind to classes. We can extends ObjectOutputStream/ObjectInputStream but it will a bit difficult to use.

You will need to convert your response to json before you can access response.body

From the docs

fetch(url)
  .then(response => response.json())
  .then(json => {
    console.log('parsed json', json) // access json.body here
  })

This is another clean solution:

sub, sup {vertical-align: baseline; position: relative; font-size: 70%;} /* 70% size of its parent element font-size which is good. */
sub {bottom: -0.6em;} /* use em becasue they adapt to parent font-size */
sup {top: -0.6em;} /* use em becasue they adapt to parent font-size */

In this way you can still use sup/sub tags but you fixed their idious behavior to always screw up paragraph line height.

So now you can do:

  <p>This is a line of text.</p>
  <p>This is a line of text, <sub>with sub text.</sub></p>
  <p>This is a line of text, <sup>with sup text.</sup></p>
  <p>This is a line of text.</p>

And your paragraph line height should not get screwed up.

Tested on IE7, IE8, FF3.6, SAFARI4, CHROME5, OPERA9

I tested using a p {line-height: 1.3;} (that is a good line height unless you want your lines to stick too close) and it still works, cause "-0.6em" is such a small amount that also with that line height the sub/sub text will fit and don't go over each other.

Forgot a detail that might be relevant I always use DOCTYPE in the 1st line of my page (specifically I use the HTML 4.01 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">). So I don't know if this solution works well when browser is in quirkmode (or not standard mode) due to lack of DOCTYPE or to a DOCTYPE that does not triggers Standard/Almost Standard mode.

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

File object docs (for Python 2) here.

A different point is that the first sentence is parsed as:

scala> List(1,2,3).++(List(4,5))
res0: List[Int] = List(1, 2, 3, 4, 5)

Whereas the second example is parsed as:

scala> List(4,5).:::(List(1,2,3))
res1: List[Int] = List(1, 2, 3, 4, 5)

So if you are using macros, you should take care.

Besides, ++ for two lists is calling ::: but with more overhead because it is asking for an implicit value to have a builder from List to List. But microbenchmarks did not prove anything useful in that sense, I guess that the compiler optimizes such calls.

Micro-Benchmarks after warming up.

scala>def time(a: => Unit): Long = { val t = System.currentTimeMillis; a; System.currentTimeMillis - t}
scala>def average(a: () => Long) = (for(i<-1 to 100) yield a()).sum/100

scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ++ List(e) } })
res1: Long = 46
scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ::: List(e ) } })
res2: Long = 46

As Daniel C. Sobrai said, you can append the content of any collection to a list using ++, whereas with ::: you can only concatenate lists.

In general, if you don't know how something works, look for an example which you can learn from.

For this problem, consider this DEMO

You can see loading content with AJAX is very easily accomplished with jQuery:

$(function(){
    // don't cache ajax or content won't be fresh
    $.ajaxSetup ({
        cache: false
    });
    var ajax_load = "<img src='http://automobiles.honda.com/images/current-offers/small-loading.gif' alt='loading...' />";

    // load() functions
    var loadUrl = "http://fiddle.jshell.net/deborah/pkmvD/show/";
    $("#loadbasic").click(function(){
        $("#result").html(ajax_load).load(loadUrl);
    });

// end  
});

Try to understand how this works and then try replicating it. Good luck.

You can find the corresponding tutorial HERE

Update

Right now the following event starts the ajax load function:

$("#loadbasic").click(function(){
        $("#result").html(ajax_load).load(loadUrl);
    });

You can also do this periodically: How to fire AJAX request Periodically?

(function worker() {
  $.ajax({
    url: 'ajax/test.html', 
    success: function(data) {
      $('.result').html(data);
    },
    complete: function() {
      // Schedule the next request when the current one's complete
      setTimeout(worker, 5000);
    }
  });
})();

I made a demo of this implementation for you HERE. In this demo, every 2 seconds (setTimeout(worker, 2000);) the content is updated.

You can also just load the data immediately:

$("#result").html(ajax_load).load(loadUrl);

Which has THIS corresponding demo.

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

To keep the code easy to read, you can use square brackets [] to quote the string containing ' or vice versa .

Could you please try this ?

Create another item in post such as post.link then assign the link to it before send post to the render function.

post.link = '/posts/+ id.toString();

So, the above render function should be following instead.

return <li key={post.id}><a href={post.link}>{post.title}</a></li>

You can simply define a style for links, which would override a:hover, a:visited etc.:

a {
  color: blue;
  text-decoration: none; /* no underline */
}

You can also use the inherit value if you want to use attributes from parent styles instead:

body {
  color: blue;
}
a {
  color: inherit; /* blue colors for links too */
  text-decoration: inherit; /* no underline */
}

@Bean(name = "restTemplateByPassSSL")
public RestTemplate restTemplateByPassSSL()
        throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    HostnameVerifier hostnameVerifier = (s, sslSession) -> true;
    SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    return new RestTemplate(requestFactory);
}

Just a little addition if one wants to parse a space separated text file line by line.

read_file = function (path)
local file = io.open(path, "rb") 
if not file then return nil end

local lines = {}

for line in io.lines(path) do
    local words = {}
    for word in line:gmatch("%w+") do 
        table.insert(words, word) 
    end    
  table.insert(lines, words)
end

file:close()
return lines;
end

In languages that support regular expressions with non-capturing groups:

((?:[^/]*/)*)(.*)

I'll explain the gnarly regex by exploding it...

(
  (?:
    [^/]*
    /
  )
  *
)
(.*)

What the parts mean:

(  -- capture group 1 starts
  (?:  -- non-capturing group starts
    [^/]*  -- greedily match as many non-directory separators as possible
    /  -- match a single directory-separator character
  )  -- non-capturing group ends
  *  -- repeat the non-capturing group zero-or-more times
)  -- capture group 1 ends
(.*)  -- capture all remaining characters in group 2

Example

To test the regular expression, I used the following Perl script...

#!/usr/bin/perl -w

use strict;
use warnings;

sub test {
  my $str = shift;
  my $testname = shift;

  $str =~ m#((?:[^/]*/)*)(.*)#;

  print "$str -- $testname\n";
  print "  1: $1\n";
  print "  2: $2\n\n";
}

test('/var/log/xyz/10032008.log', 'absolute path');
test('var/log/xyz/10032008.log', 'relative path');
test('10032008.log', 'filename-only');
test('/10032008.log', 'file directly under root');

The output of the script...

/var/log/xyz/10032008.log -- absolute path
  1: /var/log/xyz/
  2: 10032008.log

var/log/xyz/10032008.log -- relative path
  1: var/log/xyz/
  2: 10032008.log

10032008.log -- filename-only
  1:
  2: 10032008.log

/10032008.log -- file directly under root
  1: /
  2: 10032008.log

Add column to your migration file and run this command.

php artisan migrate:refresh --path=/database/migrations/your_file_name.php

You cannot use WHILE like that; see: mysql DECLARE WHILE outside stored procedure how?

You have to put your code in a stored procedure. Example:

CREATE PROCEDURE myproc()
BEGIN
    DECLARE i int DEFAULT 237692001;
    WHILE i <= 237692004 DO
        INSERT INTO mytable (code, active, total) VALUES (i, 1, 1);
        SET i = i + 1;
    END WHILE;
END

Fiddle: http://sqlfiddle.com/#!2/a4f92/1

Alternatively, generate a list of INSERT statements using any programming language you like; for a one-time creation, it should be fine. As an example, here's a Bash one-liner:

for i in {2376921001..2376921099}; do echo "INSERT INTO mytable (code, active, total) VALUES ($i, 1, 1);"; done

By the way, you made a typo in your numbers; 2376921001 has 10 digits, 237692200 only 9.

To install it, just run the command

npm install jquery

or

yarn add jquery

then you can import it in your file like

import $ from 'jquery';

By example:

# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

This is how you do CURL with sessions

//initial request with login data

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php');
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name');  //could be empty, but cause problems on some hosts
curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp');  //could be empty, but cause problems on some hosts
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

//another request preserving the session

curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile');
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

I've seen this on ImpressPages

The answer above suggests changing the function to echo data rather than return it so that it can be captured.

For a function or program that you can't modify where the return value needs to be saved to a variable (like test/[, which returns a 0/1 success value), echo $? within the command substitution:

# Test if we're remote.
isRemote="$(test -z "$REMOTE_ADDR"; echo $?)"
# Or:
isRemote="$([ -z "$REMOTE_ADDR" ]; echo $?)"

# Additionally you may want to reverse the 0 (success) / 1 (error) values
# for your own sanity, using arithmetic expansion:
remoteAddrIsEmpty="$([ -z "$REMOTE_ADDR" ]; echo $((1-$?)))"

E.g.

$ echo $REMOTE_ADDR

$ test -z "$REMOTE_ADDR"; echo $?
0
$ REMOTE_ADDR=127.0.0.1
$ test -z "$REMOTE_ADDR"; echo $?
1
$ retval="$(test -z "$REMOTE_ADDR"; echo $?)"; echo $retval
1
$ unset REMOTE_ADDR
$ retval="$(test -z "$REMOTE_ADDR"; echo $?)"; echo $retval
0

For a program which prints data but also has a return value to be saved, the return value would be captured separately from the output:

# Two different files, 1 and 2.
$ cat 1
1
$ cat 2
2

In ONLINE mode the new index is built while the old index is accessible to reads and writes. any update on the old index will also get applied to the new index. An antimatter column is used to track possible conflicts between the updates and the rebuild (ie. delete of a row which was not yet copied). See Online Index Operations. When the process is completed the table is locked for a brief period and the new index replaces the old index. If the index contains LOB columns, ONLINE operations are not supported in SQL Server 2005/2008/R2.

In OFFLINE mode the table is locked upfront for any read or write, and then the new index gets built from the old index, while holding a lock on the table. No read or write operation is permitted on the table while the index is being rebuilt. Only when the operation is done is the lock on the table released and reads and writes are allowed again.

Note that in SQL Server 2012 the restriction on LOBs was lifted, see Online Index Operations for indexes containing LOB columns.

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

This way we can check for an existing file in a particular folder:

 string curFile = @"c:\temp\test.txt";  //Your path
 Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

you can try

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));

Document doc = db.parse(is);

Yes, you can declare your new bounds object.

 var bounds = new google.maps.LatLngBounds();

Then for each marker, extend your bounds object:

bounds.extend(myLatLng);
map.fitBounds(bounds);

API: google.maps.LatLngBounds

I am using AngluarJS in html5 mode. I found following solution as most reliable:

Use angular-google-analytics library. Initialize it with something like:

//Do this in module that is always initialized on your webapp    
angular.module('core').config(["AnalyticsProvider",
  function (AnalyticsProvider) {
    AnalyticsProvider.setAccount(YOUR_GOOGLE_ANALYTICS_TRACKING_CODE);

    //Ignoring first page load because of HTML5 route mode to ensure that page view is called only when you explicitly call for pageview event
    AnalyticsProvider.ignoreFirstPageLoad(true);
  }
]);

After that, add listener on $stateChangeSuccess' and send trackPage event.

angular.module('core').run(['$rootScope', '$location', 'Analytics', 
    function($rootScope, $location, Analytics) {
        $rootScope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams, options) {
            try {
                Analytics.trackPage($location.url());
            }
            catch(err) {
              //user browser is disabling tracking
            }
        });
    }
]);

At any moment, when you have your user initalized you can inject Analytics there and make call:

Analytics.set('&uid', user.id);

I already had running postgres on host machine and didn't want to allow connections from network, so I did run temporary postgres instance in container and created database in just two lines:

# Run PostgreSQL
docker run --name postgres-container -e POSTGRES_PASSWORD=password -it -p 5433:5432 postgres

# Create database
docker exec -it postgres-container createdb -U postgres my-db

 #alertlist li:hover:after,#alertlist li.selected:after
{

    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}?

ls -lAtr | tail -1

The other solutions do not include files that start with '.'.

This command will also include '.' and '..', which may or may not be what you want:

ls -latr | tail -1

Just simple use

=Format(today(), "dd/MM/yyyy")

will solve your problem.

For people just finding this post, you should know that in newer versions (not sure on the exact version since official docs are slim on this topic) the default behavior of the InvokeCommandAction, if no CommandParameter is specified, is to pass the args of the event it's attached to as the CommandParameter. So the originals poster's XAML could be simply written as:

<i:Interaction.Triggers>
  <i:EventTrigger EventName="Navigated">
    <i:InvokeCommandAction Command="{Binding NavigatedEvent}"/>
  </i:EventTrigger>
</i:Interaction.Triggers>

Then in your command, you can accept a parameter of type NavigationEventArgs (or whatever event args type is appropriate) and it will automatically be provided.

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

this updates the screen dynamically & you can just as easily switch it off again

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

$('elemId').length doesn't work for me.

You need to put # before element id:

$('#elemId').length
---^

With vanilla JavaScript, you don't need the hash (#) e.g. document.getElementById('id_here') , however when using jQuery, you do need to put hash to target elements based on id just like CSS.

For this specific error, I installed version 20 of Crystal Report and it solved my problem: https://www.tektutorialshub.com/crystal-reports/crystal-reports-download-for-visual-studio/#Service-Pack-16

You can also download the file alone using the following link https://www.nuget.org/api/v2/package/log4net/1.2.10 rename the file to .zip and extract it.

The problem is that the base class foo has no parameterless constructor. So you must call constructor of the base class with parameters from constructor of the derived class:

public bar(int a, int b) : base(a, b)
{
    c = a * b;
}

To resolve I did the following:

1. Copied sqljdbc_auth.dll into dir: C:\Windows\System32
2. Restarted my application

Functions are not exported by default to be made available in subshells. I'd recommend you do:

source ~/anaconda3/etc/profile.d/conda.sh
conda activate my_env

In the commands above, replace ~/anaconda3/ with the path to your miniconda / anaconda installation.

Just go to cmd and install pip install pywin32 pythoncom is part of pywin32 for API window extension.... good luck

If you are using Git For Windows then it is located at

C:\Program Files\Git\mingw64\libexec\git-core

It is nice to have in mind that Git For Windows offers Git CMD, a command prompt with the PATH already set. Git CMD is available as a shortcut in

Start Menu > Programs > Git

among other options.

Just adding to all the fine answers, my version with decoration:

from __future__ import print_function
import six

def classrep(rep):
    def decorate(cls):
        class RepMetaclass(type):
            def __repr__(self):
                return rep

        class Decorated(six.with_metaclass(RepMetaclass, cls)):
            pass

        return Decorated
    return decorate


@classrep("Wahaha!")
class C(object):
    pass

print(C)

stdout:

Wahaha!

The down sides:

1. You can't declare C without a super class (no class C:)
2. C instances will be instances of some strange derivation, so it's probably a good idea to add a __repr__ for the instances as well.

Mockito comes with a helper class to save you some reflection boiler plate code:

import org.mockito.internal.util.reflection.Whitebox;

//...

@Mock
private Person mockedPerson;
private Test underTest;

// ...

@Test
public void testMethod() {
    Whitebox.setInternalState(underTest, "person", mockedPerson);
    // ...
}

Update: Unfortunately the mockito team decided to remove the class in Mockito 2. So you are back to writing your own reflection boilerplate code, use another library (e.g. Apache Commons Lang), or simply pilfer the Whitebox class (it is MIT licensed).

Update 2: JUnit 5 comes with its own ReflectionSupport and AnnotationSupport classes that might be useful and save you from pulling in yet another library.

Is this what you mean man: http://jsfiddle.net/LF75a/

You will have one function fire the next function and so on, i.e. add another function call and then add your functionONe at the bottom of it.

Please lemme know if I missed anything, hope it fits the cause :)

or this: Call a function after previous function is complete

Code:

function hulk()
{
  // do some stuff...
}
function simpsons()
{
  // do some stuff...
  hulk();
}
function thor()
{
  // do some stuff...
  simpsons();
}

If the command should work with both tabs and spaces as the delimiter I would use awk:

awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile

As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for loop:

awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile

If you want to use cut, you need to use the -f option:

cut -f100-105 myfile > outfile

If the field delimiter is different from TAB you need to specify it using -d:

cut -d' ' -f100-105 myfile > outfile

Check the man page for more info on the cut command.

For more complex tasks there is expect ( http://en.wikipedia.org/wiki/Expect ). It basically simulates a user, you can code a script how to react to specific program outputs and related stuff.

This also works in cases like ssh that prohibits piping passwords to it.

I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.

String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();

And,

I suggest you to learn about system configuration.

How to Show All Categories on System Configuration Field?

Here I solved with a good example. It working. You can check and learn the flow of code.

There are other too many examples also that you should learn.

Simulating a mouse click

My guess is that the webpage is listening to mousedown rather than click (which is bad for accessibility because when a user uses the keyboard, only focus and click are fired, not mousedown). So you should simulate mousedown, click, and mouseup (which, by the way, is what the iPhone, iPod Touch, and iPad do on tap events).

To simulate the mouse events, you can use this snippet for browsers that support DOM 2 Events. For a more foolproof simulation, fill in the mouse position using initMouseEvent instead.

// DOM 2 Events
var dispatchMouseEvent = function(target, var_args) {
  var e = document.createEvent("MouseEvents");
  // If you need clientX, clientY, etc., you can call
  // initMouseEvent instead of initEvent
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
dispatchMouseEvent(element, 'mouseover', true, true);
dispatchMouseEvent(element, 'mousedown', true, true);
dispatchMouseEvent(element, 'click', true, true);
dispatchMouseEvent(element, 'mouseup', true, true);

When you fire a simulated click event, the browser will actually fire the default action (e.g. navigate to the link's href, or submit a form).

In IE, the equivalent snippet is this (unverified since I don't have IE). I don't think you can give the event handler mouse positions.

// IE 5.5+
element.fireEvent("onmouseover");
element.fireEvent("onmousedown");
element.fireEvent("onclick");  // or element.click()
element.fireEvent("onmouseup");

Simulating keydown and keypress

You can simulate keydown and keypress events, but unfortunately in Chrome they only fire the event handlers and don't perform any of the default actions. I think this is because the DOM 3 Events working draft describes this funky order of key events:

1. keydown (often has default action such as fire click, submit, or textInput events)
2. keypress (if the key isn't just a modifier key like Shift or Ctrl)
3. (keydown, keypress) with repeat=true if the user holds down the button
4. default actions of keydown!!
5. keyup

This means that you have to (while combing the HTML5 and DOM 3 Events drafts) simulate a large amount of what the browser would otherwise do. I hate it when I have to do that. For example, this is roughly how to simulate a key press on an input or textarea.

// DOM 3 Events
var dispatchKeyboardEvent = function(target, initKeyboradEvent_args) {
  var e = document.createEvent("KeyboardEvents");
  e.initKeyboardEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchTextEvent = function(target, initTextEvent_args) {
  var e = document.createEvent("TextEvent");
  e.initTextEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchSimpleEvent = function(target, type, canBubble, cancelable) {
  var e = document.createEvent("Event");
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};

var canceled = !dispatchKeyboardEvent(element,
    'keydown', true, true,  // type, bubbles, cancelable
    null,  // window
    'h',  // key
    0, // location: 0=standard, 1=left, 2=right, 3=numpad, 4=mobile, 5=joystick
    '');  // space-sparated Shift, Control, Alt, etc.
dispatchKeyboardEvent(
    element, 'keypress', true, true, null, 'h', 0, '');
if (!canceled) {
  if (dispatchTextEvent(element, 'textInput', true, true, null, 'h', 0)) {
    element.value += 'h';
    dispatchSimpleEvent(element, 'input', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormInput();
    dispatchSimpleEvent(element, 'change', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormChange();
  }
}
dispatchKeyboardEvent(
    element, 'keyup', true, true, null, 'h', 0, '');

I don't think it is possible to simulate key events in IE.

The better solutions, when possible are:

• Replicate your data (using log-replication) to a reporting database.
• Use SAN snapshots and mount a consistent version of the DB
• Use a database which has a better fundamental transaction isolation level

The SNAPSHOT transaction isolation level was created because MS was losing sales to Oracle. Oracle uses undo/redo logs to avoid this problem. Postgres uses MVCC. In the future MS's Heckaton will use MVCC, but that's years away from being production ready.

Are you using the userdir mod?

In that case the thing is that PHP5 seems to be disabling running scripts from that location by default and you have to comment out the following lines:

<IfModule mod_userdir.c>
    <Directory /home/*/public_html>
        php_admin_flag engine Off
    </Directory>
</IfModule>

in /etc/apache2/mods-enabled/php5.conf (on a ubuntu system)

Another way of doing this in plain bash is making use of the rev command like this:

cat file | rev | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Basically, you reverse the lines of the file, then split them with cut using space as the delimiter, take the first field that cut produces and then you reverse the token again, use tr -d to delete unwanted chars and tr again to replace newline chars with ,

Also, you can avoid the first cat by doing:

rev < file | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

On my Linux I see an error with

adb shell "su -c '[your command goes here]'"

su: invalid uid/gid '-c'

The solution is on Linux

adb shell su 0 '[your command goes here]'

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

In the PHP version you can send 'true' in the last parameter, but the default is 'false'. The following algorithm is equivalent to the default PHP's hash function when passing 'sha256' as the first parameter:

public static string GetSha256FromString(string strData)
    {
        var message = Encoding.ASCII.GetBytes(strData);
        SHA256Managed hashString = new SHA256Managed();
        string hex = "";

        var hashValue = hashString.ComputeHash(message);
        foreach (byte x in hashValue)
        {
            hex += String.Format("{0:x2}", x);
        }
        return hex;
    }

Empty refers to a variable being at its default value. So if you check if a cell with a value of 0 = Empty then it would return true.

IsEmpty refers to no value being initialized.

In a nutshell, if you want to see if a cell is empty (as in nothing exists in its value) then use IsEmpty. If you want to see if something is currently in its default value then use Empty.

Several options, by order of most appropriate way:

1. Return an int from the Program.Main method
2. Throw an exception and don't handle it anywhere (use for unexpected error situations)
3. To force termination elsewhere, System.Environment.Exit (not portable! see below)

Edited 9/2013 to improve readability

Returning with a specific exit code: As Servy points out in the comments, you can declare Main with an int return type and return an error code that way. So there really is no need to use Environment.Exit unless you need to terminate with an exit code and can't possibly do it in the Main method. Most probably you can avoid that by throwing an exception, and returning an error code in Main if any unhandled exception propagates there. If the application is multi-threaded you'll probably need even more boilerplate to properly terminate with an exit code so you may be better off just calling Environment.Exit.

Another point against using Evironment.Exit - even when writing multi-threaded applications - is reusability. If you ever want to reuse your code in an environment that makes Environment.Exit irrelevant (such as a library that may be used in a web server), the code will not be portable. The best solution still is, in my opinion, to always use exceptions and/or return values that represent that the method reached some error/finish state. That way, you can always use the same code in any .NET environment, and in any type of application. If you are writing specifically an app that needs to return an exit code or to terminate in a way similar to what Environment.Exit does, you can then go ahead and wrap the thread at the highest level and handle the errors/exceptions as needed.

For fadeIn and fadeOut, only add this after super.onCreate(savedInstanceState) in your new Activity class. You don't need to create something else (No XML, no anim folder, no extra function).

overridePendingTransition(R.anim.abc_fade_in,R.anim.abc_fade_out);

Your code is very vague and not understandable, but I can provide you with an alternative.

First of all, if you want temp to go through the whole string, you can do something like this:

char *temp;
for (temp = your_string; *temp; ++temp)
    /* do something with *temp */

The term *temp as the for condition simply checks whether you have reached the end of the string or not. If you have, *temp will be '\0' (NUL) and the for ends.

Now, inside the for, you want to find the bits that compose *temp. Let's say we print the bits:

for (as above)
{
    int bit_index;
    for (bit_index = 7; bit_index >= 0; --bit_index)
    {
        int bit = *temp >> bit_index & 1;
        printf("%d", bit);
    }
    printf("\n");
}

To make it a bit more generic, that is to convert any type to bits, you can change the bit_index = 7 to bit_index = sizeof(*temp)*8-1

You can set the headers in PHP by using:

<?php
  //set headers to NOT cache a page
  header("Cache-Control: no-cache, must-revalidate"); //HTTP 1.1
  header("Pragma: no-cache"); //HTTP 1.0
  header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past

  //or, if you DO want a file to cache, use:
  header("Cache-Control: max-age=2592000"); //30days (60sec * 60min * 24hours * 30days)

?>

Note that the exact headers used will depend on your needs (and if you need to support HTTP 1.0 and/or HTTP 1.1)

If you actually want a static property of your class, that isn't currently supported in Swift. The current advice is to get around that by using global constants:

let testStr = "test"
let testStrLen = countElements(testStr)

class MyClass {
    func myFunc() {
    }
}

If you want these to be instance properties instead, you can use a lazy stored property for the length -- it will only get evaluated the first time it is accessed, so you won't be computing it over and over.

class MyClass {
    let testStr: String = "test"
    lazy var testStrLen: Int = countElements(self.testStr)

    func myFunc() {
    }
}

You can float your column divs using float: left; and give them widths.

And to make sure none of your other content gets messed up, you can wrap the floated divs within a parent div and give it some clear float styling.

Hope this helps.

Dictionary<string, List<CustomObject>> myDictionary = ListOfCustomObjects
    .GroupBy(o => o.PropertyName)
    .ToDictionary(g => g.Key, g => g.ToList());

Try using Janela or github to diagnose the problem.

You should be able to match it with: /<primaryAddress>(.+?)<\/primaryAddress>/

The content between the tags will be in the matched group.

If you don't mind not using ng-click, it works OK. You can just rename it to something else and still read the attribute, while avoiding the click handler being triggered twice problem there is at the moment.

I think the problem is terminal instructs other directives not to run. Data-binding with {{ }} is just an alias for the ng-bind directive, which is presumably cancelled by terminal.

I assume you want to link to a library called foo, its filename is usually something link foo.dll or libfoo.so.

1. Find the library
You have to find the library. This is a good idea, even if you know the path to your library. CMake will error out if the library vanished or got a new name. This helps to spot error early and to make it clear to the user (may yourself) what causes a problem.
To find a library foo and store the path in FOO_LIB use

    find_library(FOO_LIB foo)

CMake will figure out itself how the actual file name is. It checks the usual places like /usr/lib, /usr/lib64 and the paths in PATH.

You already know the location of your library. Add it to the CMAKE_PREFIX_PATH when you call CMake, then CMake will look for your library in the passed paths, too.

Sometimes you need to add hints or path suffixes, see the documentation for details: https://cmake.org/cmake/help/latest/command/find_library.html

2. Link the library From 1. you have the full library name in FOO_LIB. You use this to link the library to your target GLBall as in

  target_link_libraries(GLBall PRIVATE "${FOO_LIB}")

You should add PRIVATE, PUBLIC, or INTERFACE after the target, cf. the documentation: https://cmake.org/cmake/help/latest/command/target_link_libraries.html

If you don't add one of these visibility specifiers, it will either behave like PRIVATE or PUBLIC, depending on the CMake version and the policies set.

3. Add includes (This step might be not mandatory.)
If you also want to include header files, use find_path similar to find_library and search for a header file. Then add the include directory with target_include_directories similar to target_link_libraries.

Documentation: https://cmake.org/cmake/help/latest/command/find_path.html and https://cmake.org/cmake/help/latest/command/target_include_directories.html

If available for the external software, you can replace find_library and find_path by find_package.

First a helper function adapted from the itertools pairwise recipe to produce substrings.

import itertools
def n_wise(iterable, n = 2):
    '''n = 2 -> (s0,s1), (s1,s2), (s2, s3), ...

    n = 3 -> (s0,s1, s2), (s1,s2, s3), (s2, s3, s4), ...'''
    a = itertools.tee(iterable, n)
    for x, thing in enumerate(a[1:]):
        for _ in range(x+1):
            next(thing, None)
    return zip(*a)

Then a function the iterates over substrings, longest first, and tests for membership. (efficiency not considered)

def foo(s1, s2):
    '''Finds the longest matching substring
    '''
    # the longest matching substring can only be as long as the shortest string
    #which string is shortest?
    shortest, longest = sorted([s1, s2], key = len)
    #iterate over substrings, longest substrings first
    for n in range(len(shortest)+1, 2, -1):
        for sub in n_wise(shortest, n):
            sub = ''.join(sub)
            if sub in longest:
                #return the first one found, it should be the longest
                return sub

s = "fdomainster"
t = "exdomainid"
print(foo(s,t))

>>> 
domain
>>> 

If you have a long file with many multi-line ocurrences, it is useful to first print number lines:

cat -n file | sed -n '/Here/,/String/p'

You may actually go with ViewChild API...

• Check your forked plunker for complete code - ViewChild API

parent.ts

<button (click)="clicked()">click</button>

export class App {
  @ViewChild(Child) vc:Child;
  constructor() {
    this.name = 'Angular2'
  }

  func(e) {
    console.log(e)

  }
  clicked(){
   this.vc.getName();
  }
}

child.ts

export class Child implements OnInit{

  onInitialized = new EventEmitter<Child>();
  ...  
  ...
  getName()

  }
}

Assuming you have access to them (the properties you've declared are protected), you use them like this:

Person tom = new Person();
tom.Title = "A title";
string hisTitle = tom.Title;

These are properties. They're basically pairs of getter/setter methods (although you can have just a getter, or just a setter) with appropriate metadata. The example you've given is of automatically implemented properties where the compiler is adding a backing field. You can write the code yourself though. For example, the Title property you've declared is like this:

private string title; // Backing field
protected string Title
{
    get { return title; }  // Getter
    set { title = value; } // Setter
}

... except that the backing field is given an "unspeakable name" - one you can't refer to in your C# code. You're forced to go through the property itself.

You can make one part of a property more restricted than another. For example, this is quite common:

private string foo;
public string Foo
{
    get { return foo; }
    private set { foo = value; }
}

or as an automatically implemented property:

public string Foo { get; private set; }

Here the "getter" is public but the "setter" is private.

For replacing in place you can also do:

sed -i '' 's/\"//g' file.txt

or in Linux

sed -i 's/\"//g' file.txt

A much simpler and effective way from my perspective should be :

function onPress_ENTER()
{
        var keyPressed = event.keyCode || event.which;

        //if ENTER is pressed
        if(keyPressed==13)
        {
            alert('enter pressed');
            keyPressed=null;
        }
        else
        {
            return false;
        }
}

Please follow the below example:

public enum ErrorCodes {
NO_File("No file found. "),
private ErrorCodes(String value) { 
    this.errordesc = value; 
    }
private String errordesc = ""; 
public String errordesc() {
    return errordesc;
}
public void setValue(String errordesc) {
    this.errordesc = errordesc;
}

};

In your code call it like:

fileResponse.setErrorCode(ErrorCodes.NO_FILE.errordesc());

I kept using this all this time

You can use sklearn.feature_extraction.text.CountVectorizer:

import sklearn.feature_extraction.text # FYI http://scikit-learn.org/stable/install.html
ngram_size = 4
string = ["I really like python, it's pretty awesome."]
vect = sklearn.feature_extraction.text.CountVectorizer(ngram_range=(ngram_size,ngram_size))
vect.fit(string)
print('{1}-grams: {0}'.format(vect.get_feature_names(), ngram_size))

outputs:

4-grams: [u'like python it pretty', u'python it pretty awesome', u'really like python it']

You can set to ngram_size to any positive integer. I.e. you can split a text in four-grams, five-grams or even hundred-grams.

A possible solution is to think about it backwards: Accept a float as input and reject the input if the float is not an integer:

int n;
float f;
printf("Please enter an integer: ");
while(scanf("%f",&f)!=1 || (int)f != f)
{
    ...
}
n = f;

Though this does allow the user to enter something like 12.0, or 12e0, etc.

Firstly, as @l33tnerd said, f.close should be outside the for loop.

Secondly, you are only calling readline once, before the loop. That only reads the first line. The trick is that in Python, files act as iterators, so you can iterate over the file without having to call any methods on it, and that will give you one line per iteration:

 if data.find('!masters') != -1:
     f = open('masters.txt')
     for line in f:
           print line,
           sck.send('PRIVMSG ' + chan + " " + line)
     f.close()

Finally, you were referring to the variable lines inside the loop; I assume you meant to refer to line.

Edit: Oh and you need to indent the contents of the if statement.

If you are on ubuntu, just install pyqt5 with apt-get command:

    sudo apt-get install python3-pyqt5   # for python3

or

    sudo apt-get install python-pyqt5    # for python2

However, on Ubuntu 14.04 the python-pyqt5 package is left out [source] and need to be installed manually [source]

From my own blog post iOS 6.0 caching Ajax POST requests:

How to fix it: There are various methods to prevent caching of requests. The recommended method is adding a no-cache header. This is how it is done.

jQuery:

Check for iOS 6.0 and set Ajax header like this:

$.ajaxSetup({ cache: false });

ZeptoJS:

Check for iOS 6.0 and set the Ajax header like this:

$.ajax({
    type: 'POST',
    headers : { "cache-control": "no-cache" },
    url : ,
    data:,
    dataType : 'json',
    success : function(responseText) {…}

Server side

Java:

httpResponse.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");

Make sure to add this at the top the page before any data is sent to the client.

.NET

Response.Cache.SetNoStore();

Or

Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);

PHP

header('Cache-Control: no-cache, no-store, must-revalidate'); // HTTP 1.1.
header('Pragma: no-cache'); // HTTP 1.0.

Another good method for setting a DropDownList style combobox:

Combox1.SelectedIndex = Combox1.FindStringExact("test1")

If you want to pick columns from a ps output, any reason to not use -o?

e.g.

ps ax -o pid,vsz
ps ax -o pid,cmd

Minimum column width allocated, no padding, only single space field separator.

ps ax --no-headers -o pid:1,vsz:1,cmd

3443 24600 -bash
8419 0 [xfsalloc]
8420 0 [xfs_mru_cache]
8602 489316 /usr/sbin/apache2 -k start
12821 497240 /usr/sbin/apache2 -k start
12824 497132 /usr/sbin/apache2 -k start

Pid and vsz given 10 char width, 1 space field separator.

ps ax --no-headers -o pid:10,vsz:10,cmd

  3443      24600 -bash
  8419          0 [xfsalloc]
  8420          0 [xfs_mru_cache]
  8602     489316 /usr/sbin/apache2 -k start
 12821     497240 /usr/sbin/apache2 -k start
 12824     497132 /usr/sbin/apache2 -k start

Used in a script:-

oldpid=12824
echo "PID: ${oldpid}"
echo "Command: $(ps -ho cmd ${oldpid})"

Similar to solution of mark with some checking of variables. Also I prefer not to use $variable but rather the same string I saved it under

save your folder/directory using save dir sdir myproject and go back to that folder using goto dir gdir myproject

in addition checkout the workings of native pushd and popd they will save the current folder and this is handy for going back and forth. In this case you can also use popd after gdir myproject and go back again

# Save the current folder using sdir yourhandle to a variable you can later access the same folder fast using gdir yourhandle

function sdir {
    [[ ! -z "$1" ]] && export __d__$1="`pwd`";
}
function gdir {
    [[ ! -z "$1" ]] && cd "${!1}";
}

another handy trick is to combine the two pushd/popd and sdir and gdir wher you replace the cd in the goto dir function in pushd. This enables you to also fly back to your previous folder when making the jump to the saved folder.

# Save the current folder using sdir yourhandle to a variable you can later access the same folder fast using gdir yourhandle

function sdir {
    [[ ! -z "$1" ]] && export __d__$1="`pwd`";
}
function gdir {
    [[ ! -z "$1" ]] && pushd "${!1}";
}

If you are creating modelform from POST values initial can be assigned this way:

form = SomeModelForm(request.POST, initial={"option": "10"})

Assuming you want an actual SQL Server MERGE statement:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh);

If you also want to delete records in the target that aren't in the source:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh)
WHEN NOT MATCHED BY SOURCE THEN
    DELETE;

Because this has become a bit more popular, I feel like I should expand this answer a bit with some caveats to be aware of.

First, there are several blogs which report concurrency issues with the MERGE statement in older versions of SQL Server. I do not know if this issue has ever been addressed in later editions. Either way, this can largely be worked around by specifying the HOLDLOCK or SERIALIZABLE lock hint:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
[...]

You can also accomplish the same thing with more restrictive transaction isolation levels.

There are several other known issues with MERGE. (Note that since Microsoft nuked Connect and didn't link issues in the old system to issues in the new system, these older issues are hard to track down. Thanks, Microsoft!) From what I can tell, most of them are not common problems or can be worked around with the same locking hints as above, but I haven't tested them.

As it is, even though I've never had any problems with the MERGE statement myself, I always use the WITH (HOLDLOCK) hint now, and I prefer to use the statement only in the most straightforward of cases.

Check out this question / answer. It's more concise than @Geoff's, and also uses the builtin fputcsv function.

$result = $db_con->query('SELECT * FROM `some_table`');
if (!$result) die('Couldn\'t fetch records');
$num_fields = mysql_num_fields($result);
$headers = array();
for ($i = 0; $i < $num_fields; $i++) {
    $headers[] = mysql_field_name($result , $i);
}
$fp = fopen('php://output', 'w');
if ($fp && $result) {
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="export.csv"');
    header('Pragma: no-cache');
    header('Expires: 0');
    fputcsv($fp, $headers);
    while ($row = $result->fetch_array(MYSQLI_NUM)) {
        fputcsv($fp, array_values($row));
    }
    die;
}

In reference to @stanley's comment -

Don't try and use tap gestures to row selections to work in UITableView as it already has full tap handling....

But you must set 'Cancels Touches in View' to 'NO' on your single tap gesture recognizers or it will never get the tap events.

in your tsconfig you have to add: "esModuleInterop": true - it should help.

They are all the same in the work they do. You can do the same things using any of them. But for readability, usability, convenience etc., they differ.

You may also try to use the serialize() function. Sometimes it is very useful for debugging purposes.

Different solution for those still having issues. Hopefully I can help those trying to reinstall Mysql. Note, It's a seek and destroy mission. So be weary. Assuming your root:

apt-get purge mysql*
apt-get purge dbconfig-common #the screen used for mysql password
find / -name *mysql*          #delete any traces of mysql
#insert apt-get cleanups, autoremove,updates etc.

Originally, something leftover was interfering with my startup of mysqlserver-5.5. These commands ended up resolving the issue for myself.

I wrote a base adapter class to automatically handle item selection with a RecyclerView. Just derive your adapter from it and use drawable state lists with state_selected, like you would do with a list view.

I have a Blog Post Here about it, but here is the code:

public abstract class TrackSelectionAdapter<VH extends TrackSelectionAdapter.ViewHolder> extends RecyclerView.Adapter<VH> {
    // Start with first item selected
    private int focusedItem = 0;

    @Override
    public void onAttachedToRecyclerView(final RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);

        // Handle key up and key down and attempt to move selection
        recyclerView.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                RecyclerView.LayoutManager lm = recyclerView.getLayoutManager();

                // Return false if scrolled to the bounds and allow focus to move off the list
                if (event.getAction() == KeyEvent.ACTION_DOWN) {
                    if (keyCode == KeyEvent.KEYCODE_DPAD_DOWN) {
                        return tryMoveSelection(lm, 1);
                    } else if (keyCode == KeyEvent.KEYCODE_DPAD_UP) {
                        return tryMoveSelection(lm, -1);
                    }
                }

                return false;
            }
        });
    }

    private boolean tryMoveSelection(RecyclerView.LayoutManager lm, int direction) {
        int tryFocusItem = focusedItem + direction;

        // If still within valid bounds, move the selection, notify to redraw, and scroll
        if (tryFocusItem >= 0 && tryFocusItem < getItemCount()) {
            notifyItemChanged(focusedItem);
            focusedItem = tryFocusItem;
            notifyItemChanged(focusedItem);
            lm.scrollToPosition(focusedItem);
            return true;
        }

        return false;
    }

    @Override
    public void onBindViewHolder(VH viewHolder, int i) {
        // Set selected state; use a state list drawable to style the view
        viewHolder.itemView.setSelected(focusedItem == i);
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        public ViewHolder(View itemView) {
            super(itemView);

            // Handle item click and set the selection
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // Redraw the old selection and the new
                    notifyItemChanged(focusedItem);
                    focusedItem = getLayoutPosition();
                    notifyItemChanged(focusedItem);
                }
            });
        }
    }
} 

Also, you can do it with css selectors:

form#myform input[type='submit']

space beween elements in css elector means searching input[type='submit'] that elements at any depth of parent form#myform element

I was facing problem with Ngx line chart xAxisTickFormatting function which was called from HTML like this: [xAxisTickFormatting]="xFormat". I was unable to access my component's variable from the function declared. This solution helped me to resolve the issue to find the correct this. Hope this helps the Ngx line chart, users.

instead of using the function like this:

xFormat (value): string {
  return value.toString() + this.oneComponentVariable; //gives wrong result 
}

Use this:

 xFormat = (value) => {
   // console.log(this);
   // now you have access to your component variables
   return value + this.oneComponentVariable
 }

@Someone Somewhere I used this to clear focus:

editText.clearFocus();

and it helps

Simplest approach in printing ASCII values of a given alphabet.

Here is an example :

#include<stdio.h>
int main()
{
    //we are printing the ASCII value of 'a'
    char a ='a'
    printf("%d",a)
    return 0;
}

An alternative ugly method:

   String[] a ={"BLAH00001","DIK-11","DIK-2","MAN5"};
   String[] k=Arrays.toString(a).split(", ",2)[1].split("]")[0].split(", ");

Regarding answers by @Hugh Bothwell, @mortehu and @glglgl.

Setup Dataset for testing

import random

dataset = [random.randint(0,15) if random.random() > .6 else None for i in range(1000)]

Define implementations

def not_none(x, y=None):
    if x is None:
        return y
    return x

def coalesce1(*arg):
  return reduce(lambda x, y: x if x is not None else y, arg)

def coalesce2(*args):
    return next((i for i in args if i is not None), None)

Make test function

def test_func(dataset, func):
    default = 1
    for i in dataset:
        func(i, default)

Results on mac i7 @2.7Ghz using python 2.7

>>> %timeit test_func(dataset, not_none)
1000 loops, best of 3: 224 µs per loop

>>> %timeit test_func(dataset, coalesce1)
1000 loops, best of 3: 471 µs per loop

>>> %timeit test_func(dataset, coalesce2)
1000 loops, best of 3: 782 µs per loop

Clearly the not_none function answers the OP's question correctly and handles the "falsy" problem. It is also the fastest and easiest to read. If applying the logic in many places, it is clearly the best way to go.

If you have a problem where you want to find the 1st non-null value in a iterable, then @mortehu's response is the way to go. But it is a solution to a different problem than OP, although it can partially handle that case. It cannot take an iterable AND a default value. The last argument would be the default value returned, but then you wouldn't be passing in an iterable in that case as well as it isn't explicit that the last argument is a default to value.

You could then do below, but I'd still use not_null for the single value use case.

def coalesce(*args, **kwargs):
    default = kwargs.get('default')
    return next((a for a in arg if a is not None), default)

use ${fn:length(companies) > 0} to check the size. This returns a boolean

Here is the code that will not download courpt files

$filename = "myfile.jpg";
$file = "/uploads/images/".$filename;

header('Content-type: application/octet-stream');
header("Content-Type: ".mime_content_type($file));
header("Content-Disposition: attachment; filename=".$filename);
while (ob_get_level()) {
    ob_end_clean();
}
readfile($file);

I have included mime_content_type which will return content type of file .

To prevent from corrupt file download i have added ob_get_level() and ob_end_clean();

The window.open method is prone to cause popup blockers to complain

A better approach is:

Put a form in the webpage with an id

<form action="theUrlToGoTo" method="post" target="yourTarget" id="yourFormName"> </form>

Then use:

function openYourRequiredPage() {
var theForm = document.getElementById("yourFormName");
theForm.submit();

}

and

onclick="Javascript: openYourRequiredPage()"

You can use

method="post"

or

method="get"

As you wish

If you have a code like int arr[10] = {0, 5, 3, 64}; , and you want to append or add a value to next index, you can simply add it by typing a[5] = 5.

The main advantage of doing it like this is you can add or append a value to an any index not required to be continued one, like if I want to append the value 8 to index 9, I can do it by the above concept prior to filling up before indices. But in python by using list.append() you can do it by continued indices.

Use the -printcert command like this:

keytool -printcert -file certificate.pem

No. Unfortunately the Request object is only available until the page finishes loading - once it's complete, you'll lose all values in it unless they've been stored somewhere.

If you want to persist attributes through requests you need to either:

1. Have a hidden input in your form, such as <input type="hidden" name="myhiddenvalue" value="<%= request.getParameter("value") %>" />. This will then be available in the servlet as a request parameter.
2. Put it in the session (see request.getSession() - in a JSP this is available as simply session)

I recommend using the Session as it's easier to manage.

It miss an answer to this question, "How to duplicate selection of code" Similar to Sublime's cmd/ctrl+shift+d or Jetbrains' cmd/ctrl+d behaviour.

Install plugin Duplicate selection or line from VS Code Marketplace

This extension provides bindings for ctrl+d (Windows/Linux) and cmd+d (MacOS). To customize keyboard shortcuts Preferences -> Keyboard Shortcuts:

{
  "mac": "cmd+d",
  "key": "ctrl+d",
  "command": "geeebe.duplicateText",
  "when": "editorTextFocus"
}

Note : The shortcut does also the duplicate line so if you install it, remove your previous ctrl+d shortcut on copyLinesDownAction (if you did it before) otherwise duplicate selection can bug.

If you had a problem as me, that you have already committed some changes, but now, for any reason you want to get rid of it, the quickest way is to use git reset like this:

git reset --hard HEAD~2

I had 2 not needed commits, hence the number 2. You can change it to your own number of commits to reset.

So answering your question - if you're 5 commits ahead of remote repository HEAD, you should run this command:

git reset --hard HEAD~5

Notice that you will lose the changes you've made, so be careful!

FWIW, I had exactly the same question, but I could not find the answer here. It's probably not portable, but at least for gitolite, I can run the following to get what I want:

$ ssh [email protected] info
hello akim, this is gitolite 2.3-1 (Debian) running on git 1.7.10.4
the gitolite config gives you the following access:
     R   W     android
     R   W     bistro
     R   W     checkpn
...

Kevins answer is correct but it requires a "magic" number as follows:

var containsChar = s.indexOf(somechar) !== -1;

In that case you need to know that -1 stands for not found. I think that a bit better version would be:

var containsChar = s.indexOf(somechar) >= 0;

Assuming the following:

• You are working with Android Studio 1.2.1 or 1.2.2 (I don't have the latest yet, will edit this again when I do).
• Your Project Tool Window is displaying one of the following views: "Project", "Packages", "Android" or "Project Files"

You can delete an Android Studio module as follows:

1. In the Project Tool Window click the module you want to delete.
2. Between the Tool Bar and the Project Tool Window the tool bar you will see two "chips" that represent the path to the selected module, similar to: your-project-name > selected-module-name
3. Right click on the selected-module-name chip. A context menu with multiple sections will appear. In the third section from the bottom there will be a section that contains "Reformat Code..", "Optimize Imports..." and "Delete".
4. Select "Delete" and follow any prompts.

Is usually the easiest way to understand its meaning in computer science.

Years later, but a useful option would be to utilize XPath Axes (https://www.w3schools.com/xml/xpath_axes.asp). More specifically, you are looking to use the descendants axes.

I believe this example would do the trick:

//book[descendant::title[@lang='it']]

This allows you to select all book elements that contain a child title element (regardless of how deep it is nested) containing language attribute value equal to 'it'.

I cannot say for sure whether or not this answer is relevant to the year 2009 as I am not 100% certain that the XPath Axes existed at that time. What I can confirm is that they do exist today and I have found them to be extremely useful in XPath navigation and I am sure you will as well.

Try the following:

$("#myanchor")[0].click()

As simple as that.

You could also use the php native funcion get_browser()

IMPORTANT NOTE: You should have a browscap.ini file.

I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir, chmod, and chown. Make sure to pass extra flags to recursively affect directories:

>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third']) 
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).

>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.

>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.

EDIT I originally used commands, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;, one could potentially delete all directories).

EDIT 2 If you are using Python less than 2.7, use check_call instead of check_output. See the subprocess documentation for details.

You can always apply CCS class with rotate property - http://css-tricks.com/snippets/css/text-rotation/

To keep rotated image within your div dimensions you need to adjust CSS as well, there is no needs to use JavaScript except of adding class.

appender("STDERR", ConsoleAppender) {
    filter(EvaluatorFilter) {
      evaluator(GEventEvaluator) {
        expression = 'e.level.toInt() >= WARN.toInt()'
      }
      onMatch = NEUTRAL
      onMismatch = DENY
    }
    encoder(PatternLayoutEncoder) {
      pattern = patternExpression
    }
    target = "System.err"
  }

appender("STDOUT", ConsoleAppender) {

}

logger("org.hibernate.type", WARN)
logger("org.hibernate", WARN)
logger("org.springframework", WARN)

root(INFO,["STDERR","STDOUT"])

I think to use GEventEvaluator is simplier because there is no need to create filter classes.
I apologize for my English!

A kludgy way is:

$foo = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );

function get_first ($foo) {
    foreach ($foo as $k=>$v){
        return $v;
    }
}

print get_first($foo);

Without a RE (which I assume is what you want):

def remafterellipsis(text):
  where_ellipsis = text.find('...')
  if where_ellipsis == -1:
    return text
  return text[:where_ellipsis + 3]

or, with a RE:

import re

def remwithre(text, there=re.compile(re.escape('...')+'.*')):
  return there.sub('', text)

You can use @ and "".

        string sourse = @"{
        ""items"":[
        {
            ""itemId"":0,
            ""name"":""item0""
        },
        {
            ""itemId"":1,
            ""name"":""item1""
        }
        ]
    }";

To make reading of this page more valuable (for future search results) I made a list of libraries known to me.. As @CommonsWare mentioned there are super-similar questions/answers.. Anyway some libraries that can be used for making charts are:

Open Source:

• AnyChart (Free for non-commercial, Paid for commercial)
• MPAndroidChart
• Holo Graph Library
• aChartEngine
• ChartView
• aFreeChart
• ChartDroid
• charts4j
• GraphView
• AndroidPlot
• Drawing the 3D piechart Using Google chart Api

• RChart (pre Honeycomb - Api 11 UI)
• ShinobiControls **
• Steema TeeChart **
• Orson Charts (3D charts for Android)
• Telerik Rad Chart
• SciChart (Realtime Charts for Android)

** - means I didn't try those so I can't really recommend it but other users suggested it..

Use Memoize

The op's derivation of state is a direct manipulation of props, with no true derivation needed. In other words, if you have a prop which can be utilized or transformed directly there is no need to store the prop on state.

Given that the state value of start_time is simply the prop start_time.format("HH:mm"), the information contained in the prop is already in itself sufficient for updating the component.

However if you did want to only call format on a prop change, the correct way to do this per latest documentation would be via Memoize: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization

I'm on Windows 10 x64 and Visual Studio 2017. I copied and pasted rc.exe and rcdll.dll from:

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

to

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64

it's works with: ( qt creator 5.7.1)

The most simple way:

>>> import re
>>> string = 'This is a string, with words!'
>>> re.findall(r'\w+', string)
['This', 'is', 'a', 'string', 'with', 'words']

You could use Reflection to get the value of the property.

list = list.OrderBy( x => TypeHelper.GetPropertyValue( x, sortBy ) )
           .ToList();

Where TypeHelper has a static method like:

public static class TypeHelper
{
    public static object GetPropertyValue( object obj, string name )
    {
        return obj == null ? null : obj.GetType()
                                       .GetProperty( name )
                                       .GetValue( obj, null );
    }
}

You might also want to look at Dynamic LINQ from the VS2008 Samples library. You could use the IEnumerable extension to cast the List as an IQueryable and then use the Dynamic link OrderBy extension.

 list = list.AsQueryable().OrderBy( sortBy + " " + sortDirection );

To get the whole adress add

s.nextLine();//read the rest of the line as input

before

System.out.println("Enter Your Address: ");
String address = s.next();

<div id="sample"></div>   
 <form>
        <fieldset>
            <legend>Add New Contact</legend>
            <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
            <input type="email" name="email" placeholder="[email protected]" required /> <br />
            <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
            <input type="submit" name="submit" id= "submitButton" class="button" value="Add Contact" onClick="" />
            <input type="button" name="cancel" class="button" value="Reset" />
        </fieldset>
    </form>

<script>

    $(document).ready(function(){
         $("#submitButton").click(function(){
            $("#sample").load(filenameofyourfunction?the the variable you need);
         });
    });

</script>

Just one more solution:

$('a').on('click', function(e){
    var $link = $(e.target);
    e.preventDefault();
    if(!$link.data('lockedAt') || +new Date() - $link.data('lockedAt') > 300) {
        doSomething();
    }
    $link.data('lockedAt', +new Date());
});

Here we save the time of last click as data attribute and then check if previous click was more than 0.3 seconds ago. If it is false (less than 0.3 sec ago), just update last click time, if true, do something.

jsbin

In your code you don't get the HttpResponse, so you won't see what the server side sends you back.

you need to get the Response similar to the way you get (make) the Request. So

public static bool SendAnSMSMessage(string message)
{
  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
  httpWebRequest.ContentType = "text/json";
  httpWebRequest.Method = "POST";

  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
  {
    string json = "{ \"method\": \"send\", " +
                      "  \"params\": [ " +
                      "             \"IPutAGuidHere\", " +
                      "             \"[email protected]\", " +
                      "             \"MyTenDigitNumberWasHere\", " +
                      "             \"" + message + "\" " +
                      "             ] " +
                      "}";

    streamWriter.Write(json);
  }
  var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
  using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
  {
    var responseText = streamReader.ReadToEnd();
    //Now you have your response.
    //or false depending on information in the response
    return true;        
  }
}

I also notice in the pennysms documentation that they expect a content type of "text/json" and not "application/json". That may not make a difference, but it's worth trying in case it doesn't work.

I have modified Sky Sanders' version. The Math.floor(...) operations are evaluated in the if block

       var timeSince = function(date) {
            var seconds = Math.floor((new Date() - date) / 1000);
            var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
            if (seconds < 5){
                return "just now";
            }else if (seconds < 60){
                return seconds + " seconds ago";
            }
            else if (seconds < 3600) {
                minutes = Math.floor(seconds/60)
                if(minutes > 1)
                    return minutes + " minutes ago";
                else
                    return "1 minute ago";
            }
            else if (seconds < 86400) {
                hours = Math.floor(seconds/3600)
                if(hours > 1)
                    return hours + " hours ago";
                else
                    return "1 hour ago";
            }
            //2 days and no more
            else if (seconds < 172800) {
                days = Math.floor(seconds/86400)
                if(days > 1)
                    return days + " days ago";
                else
                    return "1 day ago";
            }
            else{

                //return new Date(time).toLocaleDateString();
                return date.getDate().toString() + " " + months[date.getMonth()] + ", " + date.getFullYear();
            }
        }

When appending only once or once every now and again, using np.append on your array should be fine. The drawback of this approach is that memory is allocated for a completely new array every time it is called. When growing an array for a significant amount of samples it would be better to either pre-allocate the array (if the total size is known) or to append to a list and convert to an array afterward.

Using np.append:

b = np.array([0])
for k in range(int(10e4)):
    b = np.append(b, k)
1.2 s ± 16.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Using python list converting to array afterward:

d = [0]
for k in range(int(10e4)):
    d.append(k)
f = np.array(d)
13.5 ms ± 277 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Pre-allocating numpy array:

e = np.zeros((n,))
for k in range(n):
    e[k] = k
9.92 ms ± 752 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

When the final size is unkown pre-allocating is difficult, I tried pre-allocating in chunks of 50 but it did not come close to using a list.

85.1 ms ± 561 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

This will enable appending to file using StreamWriter

 using (StreamWriter stream = new StreamWriter("YourFilePath", true)) {...}

This is default mode, not append to file and create a new file.

using (StreamWriter stream = new StreamWriter("YourFilePath", false)){...}
                           or
using (StreamWriter stream = new StreamWriter("YourFilePath")){...}

Anyhow if you want to check if the file exists and then do other things,you can use

using (StreamWriter sw = (File.Exists(path)) ? File.AppendText(path) : File.CreateText(path))
            {...}

I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:

In global.asax:

public class MvcApplication : HttpApplication
{
    protected void Application_EndRequest()
    {
        if (Context.Response.StatusCode == 404)
        {
            Response.Clear();

            var rd = new RouteData();
            rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
            rd.Values["controller"] = "Errors";
            rd.Values["action"] = "NotFound";

            IController c = new ErrorsController();
            c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
        }
    }
}

ErrorsController:

public sealed class ErrorsController : Controller
{
    public ActionResult NotFound()
    {
        ActionResult result;

        object model = Request.Url.PathAndQuery;

        if (!Request.IsAjaxRequest())
            result = View(model);
        else
            result = PartialView("_NotFound", model);

        return result;
    }
}

Edit:

If you're using IoC (e.g. AutoFac), you should create your controller using:

var rc = new RequestContext(new HttpContextWrapper(Context), rd);
var c = ControllerBuilder.Current.GetControllerFactory().CreateController(rc, "Errors");
c.Execute(rc);

Instead of

IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));

(Optional)

Explanation:

There are 6 scenarios that I can think of where an ASP.NET MVC3 apps can generate 404s.

Generated by ASP.NET:

• Scenario 1: URL does not match a route in the route table.

Generated by ASP.NET MVC:

• Scenario 2: URL matches a route, but specifies a controller that doesn't exist.

• Scenario 3: URL matches a route, but specifies an action that doesn't exist.

Manually generated:

• Scenario 4: An action returns an HttpNotFoundResult by using the method HttpNotFound().

• Scenario 5: An action throws an HttpException with the status code 404.

• Scenario 6: An actions manually modifies the Response.StatusCode property to 404.

Objectives

• (A) Show a custom 404 error page to the user.

• (B) Maintain the 404 status code on the client response (specially important for SEO).

• (C) Send the response directly, without involving a 302 redirection.

Solution Attempt: Custom Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customErrors>
</system.web>

Problems with this solution:

• Does not comply with objective (A) in scenarios (1), (4), (6).
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C).

Solution Attempt: HTTP Errors

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (A) in scenarios (2), (3), (5).
• Does not comply with objective (B) automatically. It must be programmed manually.

Solution Attempt: HTTP Errors with Replace

<system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• It obscures application level http exceptions. E.g. can't use customErrors section, System.Web.Mvc.HandleErrorAttribute, etc. It can't only show generic error pages.

Solution Attempt customErrors and HTTP Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customError>
</system.web>

and

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C) in scenarios (2), (3), (5).

People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the scenarios without the complexity of using an external library.

Built a tiny, confirm-like vanilla js yes / no dialog.
https://www.npmjs.com/package/yesno-dialog

Include a class example with the use keyword from Command Line Interface:

PHP Namespaces don't work on the commandline unless you also include or require the php file. When the php file is sitting in the webspace where it is interpreted by the php daemon then you don't need the require line. All you need is the 'use' line.

1. Create a new directory /home/el/bin

2. Make a new file called namespace_example.php and put this code in there:

   <?php
       require '/home/el/bin/mylib.php';
       use foobarwhatever\dingdong\penguinclass;
   
       $mypenguin = new penguinclass();
       echo $mypenguin->msg();
   ?>
   

3. Make another file called mylib.php and put this code in there:

   <?php
   namespace foobarwhatever\dingdong;
   class penguinclass 
   {
       public function msg() {
           return "It's a beautiful day chris, come out and play! " . 
                  "NO!  *SLAM!*  taka taka taka taka."; 
       }   
   }
   ?>   
   

4. Run it from commandline like this:

   el@apollo:~/bin$ php namespace_example.php 
   

5. Which prints:

   It's a beautiful day chris, come out and play!
   NO!  *SLAM!*  taka taka taka taka
   

See notes on this in the comments here: http://php.net/manual/en/language.namespaces.importing.php

Set the Delegate of the UITextField to your ViewController, add a referencing outlet between the File's Owner and the UITextField, then implement this method:

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
{
   if (textField == yourTextField) 
   {
      [textField resignFirstResponder]; 
   }
   return NO;
}

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"
        android:textColor="@android:color/white"/>
</RelativeLayout>
