If you're setting a cookie from another domain (ie you set the cookie by making an XHR cross origin request), then you need to make sure you set the withCredentials attribute to true on the XMLHttpRequest you use to fetch the cookie as described here

To increase performance when downloading a large file, the below may work a bit more efficiently:

import requests
from contextlib import closing
import csv

url = "http://download-and-process-csv-efficiently/python.csv"

with closing(requests.get(url, stream=True)) as r:
    reader = csv.reader(r.iter_lines(), delimiter=',', quotechar='"')
    for row in reader:
        # Handle each row here...
        print row   

By setting stream=True in the GET request, when we pass r.iter_lines() to csv.reader(), we are passing a generator to csv.reader(). By doing so, we enable csv.reader() to lazily iterate over each line in the response with for row in reader.

This avoids loading the entire file into memory before we start processing it, drastically reducing memory overhead for large files.

os.system('command') returns a 16 bit number, which first 8 bits from left(lsb) talks about signal used by os to close the command, Next 8 bits talks about return code of command.

Refer my answer for more detail in What is the return value of os.system() in Python?

Found the solution:

It should be:

"{'Id1':'2','Id2':'2'}"

and not

"{'Id1':'2'},{'Id2':'2'}"

Since it is only a warning you can suppress it. Go to your XML's Graphical Layout and do this:

1. Click on the right top corner red button
   
   

2. Select "Disable Issue Type" (for example)
   
   

You need to use a back_inserter:

std::copy(input.begin(), input.end(), std::back_inserter(output));

std::copy doesn't add elements to the container into which you are inserting: it can't; it only has an iterator into the container. Because of this, if you pass an output iterator directly to std::copy, you must make sure it points to a range that is at least large enough to hold the input range.

std::back_inserter creates an output iterator that calls push_back on a container for each element, so each element is inserted into the container. Alternatively, you could have created a sufficient number of elements in the std::vector to hold the range being copied:

std::vector<double> output(input.size());
std::copy(input.begin(), input.end(), output.begin());

Or, you could use the std::vector range constructor:

std::vector<double> output(input.begin(), input.end()); 

Here’s some code you can use to get a list of all the open windows. Actually, you get a dictionary where each item is a KeyValuePair where the key is the handle (hWnd) of the window and the value is its title. It also finds pop-up windows, such as those created by MessageBox.Show.

using System.Runtime.InteropServices;
using HWND = System.IntPtr;

/// <summary>Contains functionality to get all the open windows.</summary>
public static class OpenWindowGetter
{
  /// <summary>Returns a dictionary that contains the handle and title of all the open windows.</summary>
  /// <returns>A dictionary that contains the handle and title of all the open windows.</returns>
  public static IDictionary<HWND, string> GetOpenWindows()
  {
    HWND shellWindow = GetShellWindow();
    Dictionary<HWND, string> windows = new Dictionary<HWND, string>();

    EnumWindows(delegate(HWND hWnd, int lParam)
    {
      if (hWnd == shellWindow) return true;
      if (!IsWindowVisible(hWnd)) return true;

      int length = GetWindowTextLength(hWnd);
      if (length == 0) return true;

      StringBuilder builder = new StringBuilder(length);
      GetWindowText(hWnd, builder, length + 1);

      windows[hWnd] = builder.ToString();
      return true;

    }, 0);

    return windows;
  }

  private delegate bool EnumWindowsProc(HWND hWnd, int lParam);

  [DllImport("USER32.DLL")]
  private static extern bool EnumWindows(EnumWindowsProc enumFunc, int lParam);

  [DllImport("USER32.DLL")]
  private static extern int GetWindowText(HWND hWnd, StringBuilder lpString, int nMaxCount);

  [DllImport("USER32.DLL")]
  private static extern int GetWindowTextLength(HWND hWnd);

  [DllImport("USER32.DLL")]
  private static extern bool IsWindowVisible(HWND hWnd);

  [DllImport("USER32.DLL")]
  private static extern IntPtr GetShellWindow();
}

And here’s some code that uses it:

foreach(KeyValuePair<IntPtr, string> window in OpenWindowGetter.GetOpenWindows())
{
  IntPtr handle = window.Key;
  string title = window.Value;

  Console.WriteLine("{0}: {1}", handle, title);
}

Building off of Mulfix's answer, if you have Visual Studio Community 2015, try Add Reference... -> COM -> Type Libraries -> 'Microsoft Excel 15.0 Object Library'.

Sending the same cookie value with ; expires appended will not destroy the cookie.

Invalidate the cookie by setting an empty value and include an expires field as well:

Set-Cookie: token=deleted; path=/; expires=Thu, 01 Jan 1970 00:00:00 GMT

Note that you cannot force all browsers to delete a cookie. The client can configure the browser in such a way that the cookie persists, even if it's expired. Setting the value as described above would solve this problem.

Once you get the command line tools loaded as described by Nikos M in his excellent answer above you will need to agree to the gcc license and if you are using ruby gems you may need to link llvm-gcc as gcc-4.2.

If you do not do these the gem install will report "You have to install development tools first." after you have already installed them.

The steps are:

sudo gcc
sudo ln -s /usr/bin/llvm-gcc /usr/bin/gcc-4.2

The gcc must be run once under sudo so Apple can update their license info, you don't need an input file, it will update the license before it checks its arguments. The link is needed so that ruby 1.9 can find the compiler when building certain gems, such as the debugger. This may be fixed in ruby 2.x, but I'll cross that bridge when I get there.

you can horizontal your image view in a linear layout using:

 android:layout_gravity="center"

it will center your image to the parent element, if you just want to center horizontally you can use:

 android:layout_gravity="center_horizontal"

If you are looking for a range of columns, you can try this:

df.iloc[7:] = df.iloc[7:].astype(float)

The examples above will convert type to be float, for all the columns begin with the 7th to the end. You of course can use different type or different range.

I think this is useful when you have a big range of columns to convert and a lot of rows. It doesn't make you go over each row by yourself - I believe numpy do it more efficiently.

This is useful only if you know that all the required columns contain numbers only - it will not change "bad values" (like string) to be NaN for you.

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    private int[] mMeasuredDimension = new int[2];

    @Override

        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);

        int width = 0;
        int height = 0;
        for (int i = 0; i < getItemCount(); i++) {
            measureScrapChild(recycler, i, View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);


            if (getOrientation() == HORIZONTAL) {
                width = width + mMeasuredDimension[0];
                if (i == 0) {
                    height = mMeasuredDimension[1];
                }
            } else {
                height = height + mMeasuredDimension[1];
                if (i == 0) {
                    width = mMeasuredDimension[0];
                }
            }
        }
        switch (widthMode) {

            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,

                        getPaddingLeft() + getPaddingRight(), p.width);

                int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                        getPaddingTop() + getPaddingBottom(), p.height);

                view.measure(childWidthSpec, childHeightSpec);
                measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Use datetime.replace:

from datetime import datetime
dt = datetime.strptime('26 Sep 2012', '%d %b %Y')
newdatetime = dt.replace(hour=11, minute=59)

Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0); to re-position an element once it had been loaded in, however that element became blurry.

I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.

i.e. 5.5px blurs the element the most, 5.1px the least.

Just thought I'd chuck this here in case it helps anybody.

The database registers its service name(s) with the listener when it starts up. If it is unable to do so then it tries again periodically - so if the listener starts after the database then there can be a delay before the service is recognised.

If the database isn't running, though, nothing will have registered the service, so you shouldn't expect the listener to know about it - lsnrctl status or lsnrctl services won't report a service that isn't registered yet.

You can start the database up without the listener; from the Oracle account and with your ORACLE_HOME, ORACLE_SID and PATH set you can do:

sqlplus /nolog

Then from the SQL*Plus prompt:

connect / as sysdba
startup

Or through the Grid infrastructure, from the grid account, use the srvctl start database command:

srvctl start database -d db_unique_name [-o start_options] [-n node_name]

You might want to look at whether the database is set to auto-start in your oratab file, and depending on what you're using whether it should have started automatically. If you're expecting it to be running and it isn't, or you try to start it and it won't come up, then that's a whole different scenario - you'd need to look at the error messages, alert log, possibly trace files etc. to see exactly why it won't start, and if you can't figure it out, maybe ask on Database Adminsitrators rather than on Stack Overflow.

If the database can't see +DATA then ASM may not be running; you can see how to start that here; or using srvctl start asm. As the documentation says, make sure you do that from the grid home, not the database home.

An alternative solution would be to write a script to automate the Open File dialog. See AutoIt.

Also, if you can't "click" the element, my workaround is generally to do this:

element.SendKeys(Keys.Enter);

Hope this helps (Even though it's an old post)

The getPosts() function seems to be expecting $con to be global, but you're not declaring it as such.

A lot of programmers regard bald global variables as a "code smell". The alternative at the other end of the scale is to always pass around the connection resource. Partway between the two is a singleton call that always returns the same resource handle.

new Date().toISOString().split('T')[0];

This is a quicker fix in one-liner.

Hope this will help.

// WAIT FOR 200 MILISECONDS TO GET DATA //
await setTimeout(()=>{}, 200);

As noted by S.Lott,

Variable set outside init belong to the class. They're shared by all instances.

Variables created inside init (and all other method functions) and prefaced with self. belong to the object instance.

However, Note that class variables can be accessed via self.<var> until they are masked by an object variable with a similar name This means that reading self.<var> before assigning it a value will return the value of Class.<var> but afterwards it will return obj.<var> . Here is an example

In [20]: class MyClass: 
    ...:     elem = 123 
    ...:  
    ...:     def update(self,i): 
    ...:         self.elem=i  
    ...:     def print(self): 
    ...:         print (MyClass.elem, self.elem) 
    ...:  
    ...: c1 = MyClass()  
    ...: c2 = MyClass() 
    ...: c1.print() 
    ...: c2.print()

Second note: Consider slots. They may offer a better way to implement object variables.

The above post & answers are rapidly becoming dated as the development of LXD continues to enhance LXC. Yes, I know Docker hasn't stood still either.

LXD now implements a repository for LXC container images which a user can push/pull from to contribute to or reuse.

LXD's REST api to LXC now enables both local & remote creation/deployment/management of LXC containers using a very simple command syntax.

Key features of LXD are:

• Secure by design (unprivileged containers, resource restrictions and much more)
• Scalable (from containers on your laptop to thousand of compute nodes)
• Intuitive (simple, clear API and crisp command line experience)
• Image based (no more distribution templates, only good, trusted images) Live migration

There is NCLXD plugin now for OpenStack allowing OpenStack to utilize LXD to deploy/manage LXC containers as VMs in OpenStack instead of using KVM, vmware etc.

However, NCLXD also enables a hybrid cloud of a mix of traditional HW VMs and LXC VMs.

The OpenStack nclxd plugin a list of features supported include:

stop/start/reboot/terminate container
Attach/detach network interface
Create container snapshot
Rescue/unrescue instance container
Pause/unpause/suspend/resume container
OVS/bridge networking
instance migration
firewall support

By the time Ubuntu 16.04 is released in Apr 2016 there will have been additional cool features such as block device support, live-migration support.

I'm not sure if this helps, but I needed to create a macro to hold a snippet, so I simply recorded myself inserting the items and set a shortcut to it. Granted, I'm not using version 5.9 so there might be some slight version differences. To access the macro recorder go to Macro > Start Recording. Then you will perform your action and then go to Macro > Stop Recording. I'd recommend playing it back to ensure it's correct and then save and set your shortcut key.

Hope the helps.

Calling sort on a hash converts it into nested arrays and then sorts them by key, so all you need is this:

puts h.sort.map {|k,v| ["#{k}----"] + v}

And if you don't actually need the "----" part, it can be just:

puts h.sort

This is what you need :

if (Value1.StartsWith("abc"))
{
found = true;
}

Add this:

.navbar {
  position: relative;
}

javac is the Java compiler. java is the JVM and what you use to execute a Java program. You do not execute .java files, they are just source files. Presumably there is .jar somewhere (or a directory containing .class files) that is the product of building it in Eclipse:

java/src/com/mypackage/Main.java
java/classes/com/mypackage/Main.class
java/lib/mypackage.jar

From directory java execute:

java -cp lib/mypackage.jar Main arg1 arg2

This line looks questionable:

page_output.innerHTML = str_output;

You can use .innerHTML within jQuery, or you can use it without, but you have to address the selector semantically one way or the other:

$('#page_output').innerHTML /* for jQuery */
document.getElementByID('page_output').innerHTML /* for standard JS */

or better yet

$('#page_output').html(str_output);

You cannot change a table while the INSERT trigger is firing. The INSERT might do some locking which could result in a deadlock. Also, updating the table from a trigger would then cause the same trigger to fire again in an infinite recursive loop. Both of these reasons are why MySQL prevents you from doing this.

However, depending on what you're trying to achieve, you can access the new values by using NEW.fieldname or even the old values--if doing an UPDATE--with OLD.

If you had a row named full_brand_name and you wanted to use the first two letters as a short name in the field small_name you could use:

CREATE TRIGGER `capital` BEFORE INSERT ON `brandnames`
FOR EACH ROW BEGIN
  SET NEW.short_name = CONCAT(UCASE(LEFT(NEW.full_name,1)) , LCASE(SUBSTRING(NEW.full_name,2)))
END

    var count=0;
    let myArray = '{"1":"a","2":"b","3":"c","4":"d"}'
    var data = JSON.parse(myArray);
    for (let key in data) {
      let value =  data[key]; // get the value by key
      console.log("key: , value:", key, value);
      count = count + 1;
    }
   console.log("size:",count);

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

my suggestion is...create role in oracle using

create role <role_name>;

then assign privileges to that role using

grant select on <table_name> to <role_name>;

then assign that group of privileges via that role to any user by using

grant  <role_name> to <user_name>...;

When you use the IntelliJ IDE, all the project-specific settings for the project are stored under the .idea folder.

Project settings are stored with each specific project as a set of xml files under the .idea folder. If you specify the default project settings, these settings will be automatically used for each newly created project.

Check this documentation for the IDE settings and here is their recommendation on Source Control and an example .gitignore file.

Note: If you are using git or some version control system, you might want to set this folder "ignore". Example - for git, add this directory to .gitignore. This way, the application is not IDE-specific.

Update 2020, May:

Setting position: absolute and then transform: rotate(45deg) will provide a background:

div {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  outline: 2px dashed slateBlue;_x000D_
  overflow: hidden;_x000D_
}_x000D_
div img {_x000D_
  position: absolute;_x000D_
  transform: rotate(45deg);_x000D_
  z-index: -1;_x000D_
  top: 40px;_x000D_
  left: 40px;_x000D_
}

<div>_x000D_
  <img src="https://placekitten.com/120/120" />_x000D_
  <h1>Hello World!</h1>_x000D_
</div>

Original Answer:

In my case, the image size is not so large that I cannot have a rotated copy of it. So, the image has been rotated with photoshop. An alternative to photoshop for rotating images is online tool too for rotating images. Once rotated, I'm working with the rotated-image in the background property.

div.with-background {
    background-image: url(/img/rotated-image.png);
    background-size:     contain;
    background-repeat:   no-repeat;
    background-position: top center;
}

Good Luck...

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

You can do this in two ways:

1. ElementMatch - $elemMatch (as explained in above answers)

   db.users.find({ awards: { $elemMatch: {award:'Turing Award', year:1977} } })

2. Use $and with find

   db.getCollection('users').find({"$and":[{"awards.award":"Turing Award"},{"awards.year":1977}]})

I had this problem as well, and I must have tried 20 different path adding solutions before I worked it out. Someone mentioned it above almost as a side note, but this was exactly my issue:

make sure you are running a 64-bit version of java.

The code above exports data without the heading columns which is weird. Here's how to do it. You have to merge the two files later though using text a editor.

SELECT column_name FROM information_schema.columns WHERE table_schema = 'my_app_db' AND table_name = 'customers' INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/customers_heading_cols.csv' FIELDS TERMINATED BY '' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY ',';

You can force it (browser permitting, I imagine) by inserting line breaks in the HTML source, like this:

<INPUT value="Line 1
Line 2">

Of course working out where to place the line breaks is not necessarily trivial...

If you can use an HTML <BUTTON> instead of an <INPUT>, such that the button label is the element's content rather than its value attribute, placing that content inside a <SPAN> with a width attribute that is a few pixels narrower than that of the button seems to do the trick (even in IE6 :-).

I tried to do in a NSObject Class and this worked for me:

DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(300)) {  
print("Bang!") }

The method add of Set returns a boolean whether a value already exists (true if it does not exist, false if it already exists, see Set documentation).

So just iterate through all the values:

public Set<Integer> findDuplicates(List<Integer> listContainingDuplicates)
{ 
  final Set<Integer> setToReturn = new HashSet<>(); 
  final Set<Integer> set1 = new HashSet<>();

  for (Integer yourInt : listContainingDuplicates)
  {
   if (!set1.add(yourInt))
   {
    setToReturn.add(yourInt);
   }
  }
  return setToReturn;
}

To fix this, open the SQL Server Management Studio and click New Query. Then type:

USE mydatabase
exec sp_changedbowner 'sa', 'true'

CommandArgument='<%#Eval("ScrapId").Tostring()+ Eval("UserId")%>
//added the comment function

Make sure you type the command from the "App" Directory

In some cases you may not be able to suspend, or for that matter take any of the "Power" actions on the VM. You may also already have multiple VMs up and running. Use this process to identify the correct PID to kill.

On Windows 7 - Open Task Manager - Look for processes with the name, "vmware-vmx.exe", note the PIDs.

Switch to the Performance tab and start the "Resource Monitor". Expand the "Disk Activity" panel. Sort the "File" column. Look for the appropriate vmdk file for the VM you want to kill. The "Image" column will have the "vmware-vmx" process listed. Note the PID.

Switch back to the "Processes" tab and kill the PID.

Try setting the file path using (for anaconda3)...

export PATH=~/anaconda3/bin:$PATH

Then check whether it worked with...

conda --version

This worked for me when 'conda' was returning 'command not found'.

There is no such file open mode as "wr" in your code:

fopen("logs.txt", "wr") 

The file open modes in PHP http://php.net/manual/en/function.fopen.php is the same as in C: http://www.cplusplus.com/reference/cstdio/fopen/

There are the following main open modes "r" for read, "w" for write and "a" for append, and you cannot combine them. You can add other modifiers like "+" for update, "b" for binary. The new C standard adds a new standard subspecifier ("x"), supported by PHP, that can be appended to any "w" specifier (to form "wx", "wbx", "w+x" or "w+bx"/"wb+x"). This subspecifier forces the function to fail if the file exists, instead of overwriting it.

Besides that, in PHP 5.2.6, the 'c' main open mode was added. You cannot combine 'c' with 'a', 'r', 'w'. The 'c' opens the file for writing only. If the file does not exist, it is created. If it exists, it is neither truncated (as opposed to 'w'), nor the call to this function fails (as is the case with 'x'). 'c+' Open the file for reading and writing; otherwise it has the same behavior as 'c'.

Additionally, and in PHP 7.1.2 the 'e' option was added that can be combined with other modes. It set close-on-exec flag on the opened file descriptor. Only available in PHP compiled on POSIX.1-2008 conform systems.

So, for the task as you have described it, the best file open mode would be 'a'. It opens the file for writing only. It places the file pointer at the end of the file. If the file does not exist, it attempts to create it. In this mode, fseek() has no effect, writes are always appended.

Here is what you need, as has been already pointed out above:

fopen("logs.txt", "a") 

I found that when I used the this callback function to ignore SSL certificates [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

I always got the error message Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send. which sounds like the results you are having.

I found this forum post which lead me to the function below. I run this once inside the scope of my other code and it works for me.

    [System.Net.ServicePointManager]::CertificatePolicy = $TrustAll
}

when you want to brightness or darker of background-color, you can use this css code

.brighter-span {
  filter: brightness(150%);
}

.darker-span {
  filter: brightness(50%);
}

As per https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe, percentage values are no longer allowed. But the following worked for me

<iframe width="100%" height="this.height=window.innerHeight;" style="border:none" src=""></iframe>

Though width:100% works, height:100% does not work. So window.innerHeight has been used. You can also use css pixels for height.

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

For List<List<List<x>>> and so on, use

list.SelectMany(x => x.SelectMany(y => y)).ToList();

This has been posted in a comment, but it does deserves a separate reply in my opinion.

count(*) is an aggregate function. Aggregate functions need to be grouped for a meaningful results. You can read: count columns group by

Add property:

-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box;    /* Firefox, other Gecko */
box-sizing: border-box;         /* Opera/IE 8+ */

Note: This won't work in Internet Explorer below version 8.

On Mac: IntelliJ Idea ? Preferences

In the Preferences Dialog,

1. Editor ? Colors & Fonts ? Font.
2. Click on Save As, enter the scheme name such as the mac user name.
3. Change the Size as required.

and don't care about signed/unsigned or different sizes

Inheritance is pretty enticing especially coming from procedural-land and it often looks deceptively elegant. I mean all I need to do is add this one bit of functionality to some other class, right? Well, one of the problems is that

inheritance is probably the worst form of coupling you can have

Your base class breaks encapsulation by exposing implementation details to subclasses in the form of protected members. This makes your system rigid and fragile. The more tragic flaw however is the new subclass brings with it all the baggage and opinion of the inheritance chain.

The article, Inheritance is Evil: The Epic Fail of the DataAnnotationsModelBinder, walks through an example of this in C#. It shows the use of inheritance when composition should have been used and how it could be refactored.

double click the button and add write // this.close();

  private void buttonClick(object sender, EventArgs e)
{
    this.Close();
}

This is because the LEFT OUTER Join is doing more work than an INNER Join BEFORE sending the results back.

The Inner Join looks for all records where the ON statement is true (So when it creates a new table, it only puts in records that match the m.SubID = a.SubID). Then it compares those results to your WHERE statement (Your last modified time).

The Left Outer Join...Takes all of the records in your first table. If the ON statement is not true (m.SubID does not equal a.SubID), it simply NULLS the values in the second table's column for that recordset.

The reason you get the same number of results at the end is probably coincidence due to the WHERE clause that happens AFTER all of the copying of records.

Alex, Gary:

As requested, here is my comment posted as an answer:

var rt = ($(window).width() - ($whatever.offset().left + $whatever.outerWidth()));

Thanks for letting me know.

In pseudo code that can be expressed as:

The right offset is:

The window's width MINUS
( The element's left offset PLUS the element's outer width )

With VS2010+ there is a plugin solution: Line Endings Unifier.

With the plugin installed you can right click files and folders in the solution explorer and invoke the menu item Unify Line Endings in this file

Configuration for this is available via

Tools -> Options -> Line Endings Unifier.

The default file extension list that is included is pretty narrow:

 .cpp; .c; .h; .hpp; .cs; .js; .vb; .txt;

Might want to use something like:

 .cpp; .c; .h; .hpp; .cs; .js; .vb; .txt; .scss; .coffee; .ts; .jsx; .markdown; .config

So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.

Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

Below is a blog for more details..

Happy coding.. :)

Thanks, Ayan

No. Actually it's the "same" as

char array[] = {'O', 'n', 'e', ..... 'i','c','\0');

Every character is a separate element, with an additional \0 character as a string terminator.

I quoted "same", because there are some differences between char * array and char array[]. If you want to read more, take a look at C: differences between char pointer and array

Further to previous answers, you should note that a column defined as VARCHARS(10) will store 10 bytes, not 10 characters unless you define it as VARCHAR2(10 CHAR)

[The OP's question seems to be number related... this is just in case anyone else has a similar issue]

$("div").click(function() {
  var txtClass = $(this).attr("class");
  console.log("Class Name : "+txtClass);
});

One you convert your image to gray-scale you cannot got back. You have gone from three channel to one, when you try to go back all three numbers will be the same. So the short answer is no you cannot go back. The reason your backtorgb function this throwing that error is because it needs to be in the format:

CvtColor(input, output, CV_GRAY2BGR)

OpenCV use BGR not RGB, so if you fix the ordering it should work, though your image will still be gray.

sp_lock

When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:

SELECT object_name(16003073)

EDIT :

There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/

I did it different way, because I only had access to management webpage. I created simple "snippet" which delete queues in Javascript. Here it is:

function zeroPad(num, places) {
  var zero = places - num.toString().length + 1;
  return Array(+(zero > 0 && zero)).join("0") + num;
}
var queuePrefix = "PREFIX"
for(var i=0; i<255; i++){ 
   var queueid = zeroPad(i, 4);
   $.ajax({url: '/api/queues/vhost/'+queuePrefix+queueid, type: 'DELETE', success: function(result) {console.log('deleted '+queuePrefix+queueid)}});
}

All my queues was in format: PREFIX_0001 to PREFIX_0XXX

You can control client cache with HTTP headers. This works in any web framework.

You can set the directives these headers to have fine grained control over how and when to enable|disable cache:

• Cache-Control
• Surrogate-Control
• Expires
• ETag (very good one)
• Pragma (if you want to support old browsers)

Good caching is good, but very complex, in all computer systems. Take a look at https://helmetjs.github.io/docs/nocache/#the-headers for more information.

Add the maven repository outside the buildscript configuration block of your main build.gradle file as follows:

repositories {
        maven {
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
    }

Make sure that you add them after the following:

apply plugin: 'com.android.application'

Some might want certain class constants public while others private.

private keyword can be used to limit the scope of constants within the same swift file.

class MyClass {

struct Constants {

    static let testStr = "test"
    static let testStrLen = testStr.characters.count

    //testInt will not be accessable by other classes in different swift files
    private static let testInt = 1
}

func ownFunction()
{

    var newInt = Constants.testInt + 1

    print("Print testStr=\(Constants.testStr)")
}

}

Other classes will be able to access your class constants like below

class MyClass2
{

func accessOtherConstants()
{
    print("MyClass's testStr=\(MyClass.Constants.testStr)")
}

} 

You should take a look the reference documentation. It's well explained.

In your case, I think you cannot use between because you need to pass two parameters

Between - findByStartDateBetween … where x.startDate between ?1 and ?2

In your case take a look to use a combination of LessThan or LessThanEqual with GreaterThan or GreaterThanEqual

• LessThan/LessThanEqual

LessThan - findByEndLessThan … where x.start< ?1

LessThanEqual findByEndLessThanEqual … where x.start <= ?1

• GreaterThan/GreaterThanEqual

GreaterThan - findByStartGreaterThan … where x.end> ?1

GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1

You can use the operator And and Or to combine both.

For a simple way, use system():

#include <stdlib.h>
...
int status = system("./foo 1 2 3");

system() will wait for foo to complete execution, then return a status variable which you can use to check e.g. exitcode (the command's exitcode gets multiplied by 256, so divide system()'s return value by that to get the actual exitcode: int exitcode = status / 256).

The manpage for wait() (in section 2, man 2 wait on your Linux system) lists the various macros you can use to examine the status, the most interesting ones would be WIFEXITED and WEXITSTATUS.

Alternatively, if you need to read foo's standard output, use popen(3), which returns a file pointer (FILE *); interacting with the command's standard input/output is then the same as reading from or writing to a file.

getYear is no longer used and has been replaced by the getFullYear method.

The getYear method returns the year minus 1900; thus:

• For years greater than or equal to 2000, the value returned by getYear is 100 or greater. For example, if the year is 2026, getYear returns 126.
• For years between and including 1900 and 1999, the value returned by getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76.
• For years less than 1900, the value returned by getYear is less than 0. For example, if the year is 1800, getYear returns -100.
• To take into account years before and after 2000, you should use getFullYear instead of getYear so that the year is specified in full.

a sleaker way to match special chars:

/\W|_/g

\W Matches any character that is not a word character (alphanumeric & underscore).

Underscore is considered a special character so add boolean to either match a special character or _

You could use a closure. Just modify your code like this:

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
    };
})(marker,content,infowindow));  

Here is the DEMO

You should be able to attach an event handler to the onchange event of the input and have that call a function to set the text in your span.

<script type="text/javascript">
  $(function() {
     $("input:file").change(function (){
       var fileName = $(this).val();
       $(".filename").html(fileName);
     });
  });
</script>

You may want to add IDs to your input and span so you can select based on those to be specific to the elements you are concerned with and not other file inputs or spans in the DOM.

To get the memory usage of just your application (as opposed to the shared libraries it uses, you need to use the Linux smaps interface). This answer explains it well.

The problem is described (among other) in this article.

#box is relatively positioned, which makes it part of the "flow" of the page. Your other divs are absolutely positioned, so they are removed from the page's "flow".

Page flow means that the positioning of an element effects other elements in the flow.

In other words, as #box now sees the dom, .a and .b are no longer "inside" #box.

To fix this, you would want to make everything relative, or everything absolute.

One way would be:

.a {
   position:relative;
   margin-top:10px;
   margin-left:10px;
   background-color:red;
   width:210px;
   padding: 5px;
}

How many characters can a type text field store?

According to Documentation You can use maximum of 21,844 characters if the charset is UTF8

If a lot, would I be able to specify length in the db text type field as I would with varchar?

You dont need to specify the length. If you need more character use data types MEDIUMTEXT or LONGTEXT. With VARCHAR, specifieng length is not for Storage requirement, it is only for how the data is retrieved from data base.

If you are looking for a library to carry out client-side image compression, you can check this out:compress.js. This will basically help you compress multiple images purely with JavaScript and convert them to base64 string. You can optionally set the maximum size in MB and also the preferred image quality.

If you are asking the difference between RDD.map and RDD.flatMap in Spark, map transforms an RDD of size N to another one of size N . eg.

myRDD.map(x => x*2)

for example, if myRDD is composed of Doubles .

While flatMap can transform the RDD into anther one of a different size: eg.:

myRDD.flatMap(x =>new Seq(2*x,3*x))

which will return an RDD of size 2*N or

myRDD.flatMap(x =>if x<10 new Seq(2*x,3*x) else new Seq(x) )

I can't give an authoritative answer, but provide an overview of a likely cause. This reference shows pretty clearly that for the instructions in the body of your loop there is a 3:1 ratio between latency and throughput. It also shows the effects of multiple dispatch. Since there are (give-or-take) three integer units in modern x86 processors, it's generally possible to dispatch three instructions per cycle.

So between peak pipeline and multiple dispatch performance and failure of these mechanisms, we have a factor of six in performance. It's pretty well known that the complexity of the x86 instruction set makes it quite easy for quirky breakage to occur. The document above has a great example:

The Pentium 4 performance for 64-bit right shifts is really poor. 64-bit left shift as well as all 32-bit shifts have acceptable performance. It appears that the data path from the upper 32 bits to the lower 32 bit of the ALU is not well designed.

I personally ran into a strange case where a hot loop ran considerably slower on a specific core of a four-core chip (AMD if I recall). We actually got better performance on a map-reduce calculation by turning that core off.

Here my guess is contention for integer units: that the popcnt, loop counter, and address calculations can all just barely run at full speed with the 32-bit wide counter, but the 64-bit counter causes contention and pipeline stalls. Since there are only about 12 cycles total, potentially 4 cycles with multiple dispatch, per loop body execution, a single stall could reasonably affect run time by a factor of 2.

The change induced by using a static variable, which I'm guessing just causes a minor reordering of instructions, is another clue that the 32-bit code is at some tipping point for contention.

I know this is not a rigorous analysis, but it is a plausible explanation.

Assuming you're referring to this plugin, your code should be:

// To Store
$(function() {
    $.session.set("myVar", "value");
});


// To Read
$(function() {
    alert($.session.get("myVar"));
});

Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown file, which is displayed on the project page.

This splits the Seatblocks by space and gives each its own row.

In [44]: s = df['Seatblocks'].str.split(' ').apply(Series, 1).stack()

Or, to give each colon-separated string in its own column:

In [50]: df.join(s.apply(lambda x: Series(x.split(':'))))

This is a little ugly, but maybe someone will chime in with a prettier solution.

HxD -- it's a hexeditor, but it allows in place edits, and doesn't barf on large files.

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

I solved this problem by doing these:

1. Right click on your project.

2. Click on Team

3. Click Refresh/Cleaup

Part of the problem here is that the strings usually used to represent timezones are not actually unique. "EST" only means "America/New_York" to people in North America. This is a limitation in the C time API, and the Python solution is… to add full tz features in some future version any day now, if anyone is willing to write the PEP.

You can format and parse a timezone as an offset, but that loses daylight savings/summer time information (e.g., you can't distinguish "America/Phoenix" from "America/Los_Angeles" in the summer). You can format a timezone as a 3-letter abbreviation, but you can't parse it back from that.

If you want something that's fuzzy and ambiguous but usually what you want, you need a third-party library like dateutil.

If you want something that's actually unambiguous, just append the actual tz name to the local datetime string yourself, and split it back off on the other end:

d = datetime.datetime.now(pytz.timezone("America/New_York"))
dtz_string = d.strftime(fmt) + ' ' + "America/New_York"

d_string, tz_string = dtz_string.rsplit(' ', 1)
d2 = datetime.datetime.strptime(d_string, fmt)
tz2 = pytz.timezone(tz_string)

print dtz_string 
print d2.strftime(fmt) + ' ' + tz_string

Or… halfway between those two, you're already using the pytz library, which can parse (according to some arbitrary but well-defined disambiguation rules) formats like "EST". So, if you really want to, you can leave the %Z in on the formatting side, then pull it off and parse it with pytz.timezone() before passing the rest to strptime.

For fine tuning the position of an inline-block item, use top and left:

  position: relative;
  top: 5px;
  left: 5px;

Thanks CSS-Tricks!

If you need the width of something that's hidden and you can't un-hide it for whatever reason, you can clone it, change the CSS so it displays off the page, make it invisible, and then measure it. The user will be none the wiser if it's hidden and deleted afterwards.

Some of the other answers here just make the visibility hidden which works, but it will take up a blank spot on your page for a fraction of a second.

Example:

$itemClone = $('.hidden-item').clone().css({
        'visibility': 'hidden',
        'position': 'absolute',
        'z-index': '-99999',
        'left': '99999999px',
        'top': '0px'
    }).appendTo('body');
var width = $itemClone.width();
$itemClone.remove();

Just to share, I've developed my own script to do it. Feel free to use it. It generates "SELECT" statements that you can then run on the tables to generate the "INSERT" statements.

Firstly, get the Android SDK location in Android Studio : Android Studio -> Preferences -> Appearance & Behaviour -> System Settings -> Android SDK -> Android SDK Location

Then execute the following commands in terminal

export ANDROID_HOME=Paste here your SDK location

export PATH=$PATH:$ANDROID_HOME/bin

It is done.

Depending whether or not you know the image format, here are ways you can do it :

Download Image to a file, knowing the image format

using (WebClient webClient = new WebClient()) 
{
   webClient.DownloadFile("http://yoururl.com/image.png", "image.png") ; 
}

Download Image to a file without knowing the image format

You can use Image.FromStream to load any kind of usual bitmaps (jpg, png, bmp, gif, ... ), it will detect automaticaly the file type and you don't even need to check the url extension (which is not a very good practice). E.g:

using (WebClient webClient = new WebClient()) 
{
    byte [] data = webClient.DownloadData("https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t34.0-12/10555140_10201501435212873_1318258071_n.jpg?oh=97ebc03895b7acee9aebbde7d6b002bf&oe=53C9ABB0&__gda__=1405685729_110e04e71d9");

   using (MemoryStream mem = new MemoryStream(data)) 
   {
       using (var yourImage = Image.FromStream(mem)) 
       { 
          // If you want it as Png
           yourImage.Save("path_to_your_file.png", ImageFormat.Png) ; 

          // If you want it as Jpeg
           yourImage.Save("path_to_your_file.jpg", ImageFormat.Jpeg) ; 
       }
   } 

}

Note : ArgumentException may be thrown by Image.FromStream if the downloaded content is not a known image type.

Check this reference on MSDN to find all format available. Here are reference to WebClient and Bitmap.

The answer is in the current spec:

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading.

Examples of sections would be chapters, the various tabbed pages in a tabbed dialog box, or the numbered sections of a thesis. A Web site's home page could be split into sections for an introduction, news items, and contact information.

Authors are encouraged to use the article element instead of the section element when it would make sense to syndicate the contents of the element.

The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting, authors are encouraged to use the div element instead. A general rule is that the section element is appropriate only if the element's contents would be listed explicitly in the document's outline.

Reference:

• http://www.w3.org/TR/html5/sections.html#the-section-element
• http://www.whatwg.org/specs/web-apps/current-work/multipage/sections.html#the-section-element

Also see:

• http://html5doctor.com/the-section-element/
• http://www.impressivewebs.com/html5-section/

It looks like there's been a lot of confusion about this element's purpose, but the one thing that's agreed upon is that it is not a generic wrapper, like <div> is. It should be used for semantic purposes, and not a CSS or JavaScript hook (although it certainly can be styled or "scripted").

A better example, from my understanding, might look something like this:

<div id="content">
  <article>
     <h2>How to use the section tag</h2>
     <section id="disclaimer">
         <h3>Disclaimer</h3>
         <p>Don't take my word for it...</p>
     </section>
     <section id="examples">
       <h3>Examples</h3>
       <p>But here's how I would do it...</p>
     </section>
     <section id="closing_notes">
       <h3>Closing Notes</h3>
       <p>Well that was fun. I wonder if the spec will change next week?</p>
     </section>
  </article>
</div>

Note that <div>, being completely non-semantic, can be used anywhere in the document that the HTML spec allows it, but is not necessary.

It sounds like you want to re-implement, or possibly extend, AuthorizeAttribute. If so, you should make sure that you inherit that, and not ActionFilterAttribute, in order to let ASP.NET MVC do more of the work for you.

Also, you want to make sure that you authorize before you do any of the real work in the action method - otherwise, the only difference between logged in and not will be what page you see when the work is done.

public class CustomAuthorizeAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        // Do whatever checking you need here

        // If you want the base check as well (against users/roles) call
        base.OnAuthorization(filterContext);
    }
}

There is a good question with an answer with more details here on SO.

I installed cudatoolkit 11 and copy dll C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.1\bin to C:\Windows\System32. It fixed for PyCharm but not for Anaconda jupyter:

[name: "/device:CPU:0" device_type: "CPU" memory_limit: 268435456 locality { } incarnation: 6812190123916921346 , name: "/device:GPU:0" device_type: "GPU" memory_limit: 13429637120 locality { bus_id: 1

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

I believe Enterprise Architect can do that.

I had a similar problem because the app store version was missing iOS 10.1 support in Xcode 8 and they haven't rolled an update yet. This caused the "Xcode: Could not locate device support files" problem. You can download the latest update https://developer.apple.com/download/ and it is more current and supports iOS 10.1 (14B72c).

As Rutesh and jmservera pointed out, the distinction is a fuzzy one. Historically, they were different, but through the 90's these two previously distinct categories blended features and effectively merged. At this point is is probably best to imagine that the "App Server" product category is a strict superset of the "web server" category.

Some history. In early days of the Mosaic browser and hyperlinked content, there evolved this thing called a "web server" that served web page content and images over HTTP. Most of the content was static, and the HTTP 1.0 protocol was just a way to ship files around. Quickly the "web server" category evolved to include CGI capability - effectively launching a process on each web request to generate dynamic content. HTTP also matured and the products became more sophisticated, with caching, security, and management features. As the technology matured, we got company-specific Java-based server-side technology from Kiva and NetDynamics, which eventually all merged into JSP. Microsoft added ASP, I think in 1996, to Windows NT 4.0. The static web server had learned some new tricks, so that it was an effective "app server" for many scenarios.

In a parallel category, the app server had evolved and existed for a long time. companies delivered products for Unix like Tuxedo, TopEnd, Encina that were philosophically derived from Mainframe application management and monitoring environments like IMS and CICS. Microsoft's offering was Microsoft Transaction Server (MTS), which later evolved into COM+. Most of these products specified "closed" product-specific communications protocols to interconnect "fat" clients to servers. (For Encina, the comms protocol was DCE RPC; for MTS it was DCOM; etc.) In 1995/96, these traditional app server products began to embed basic HTTP communication capability, at first via gateways. And the lines began to blur.

Web servers got more and more mature with respect to handling higher loads, more concurrency, and better features. App servers delivered more and more HTTP-based communication capability.

At this point the line between "app server" and "web server" is a fuzzy one. But people continue to use the terms differently, as a matter of emphasis. When someone says "web server" you often think HTTP-centric, web UI, oriented apps. When someone says "App server" you may think "heavier loads, enterprise features, transactions and queuing, multi-channel communication (HTTP + more). But often it is the same product that serves both sets of workload requirements.

• WebSphere, IBM's "app server" has its own bundled web server.
• WebLogic, another traditional app server, likewise.
• Windows, which is Microsoft's App Server (in addition to being its File&Print Server, Media Server, etc.), bundles IIS.

I've found this:

  sc query "ServiceName" | findstr RUNNING  

seems to do roughly the right thing. But, I'm worried that's not generalized enough to work on non-english operating systems.

Try: localhost:8080/phpmyadmin/

I'm consciously writing this answer to an old question with this in mind, because the other answers didn't help me.

I got the Illegal Instruction: 4 while running the binary on the same system I had compiled it on, so -mmacosx-version-min didn't help.

I was using gcc in Code Blocks 16 on Mac OS X 10.11.

However, turning off all of Code Blocks' compiler flags for optimization worked. So look at all the flags Code Blocks set (right-click on the Project -> "Build Properties") and turn off all the flags you are sure you don't need, especially -s and the -Oflags for optimization. That did it for me.

Super easy and works, but not sure why....

I was running into a situation where in my apps' dashboard, when I went to:

More > View logs

I wouldn't get an output, just hung...

So I did a google and found this:

Heroku CLI plugin to list and create builds for Heroku apps.

I installed it and ran:

heroku builds -a example-app /* Lists 10 most recently created builds for example-app, that's where you get the id for the next step*/

Then enter:

heroku builds:output your-app-id-number -a example-app 

And that's it, you should get back what you normally see in the dashboard GUI or locally.

Hope this helps someone like it did me!

There is also strptime() which expects exactly one format:

$a = strptime('22-09-2008', '%d-%m-%Y');
$timestamp = mktime(0, 0, 0, $a['tm_mon']+1, $a['tm_mday'], $a['tm_year']+1900);

Please note that one should define a Handler and a Runnable in class scope, so that it is created once.removeCallbacks(Runnable) works correctly unless one defines them multiple times. Please look at following examples for better understanding:

Incorrect way :

    public class FooActivity extends Activity {
           private void handleSomething(){
                Handler handler = new Handler();
                Runnable runnable = new Runnable() {
                   @Override
                   public void run() {
                      doIt();
                  }
               };
              if(shouldIDoIt){
                  //doIt() works after 3 seconds.
                  handler.postDelayed(runnable, 3000);
              } else {
                  handler.removeCallbacks(runnable);
              }
           }

          public void onClick(View v){
              handleSomething();
          }
    } 

If you call onClick(..) method, you never stop doIt() method calling before it call. Because each time creates new Handler and new Runnable instances. In this way, you lost necessary references which belong to handler and runnable instances.

Correct way :

 public class FooActivity extends Activity {
        Handler handler = new Handler();
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                doIt();
            }
        };
        private void handleSomething(){
            if(shouldIDoIt){
                //doIt() works after 3 seconds.
                handler.postDelayed(runnable, 3000);
            } else {
                handler.removeCallbacks(runnable);
            }
       }

       public void onClick(View v){
           handleSomething();
       }
 } 

In this way, you don't lost actual references and removeCallbacks(runnable) works successfully.

Key sentence is that 'define them as global in your Activity or Fragment what you use'.

This is how I do it, and Google does it my way.

• Break before the symbol for non-assignment operators.
• Break after the symbol for = and for ,.

In your case, since you're using 120 characters, you can break it after the assignment operator resulting in

private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper =
        new HashMap<Class<? extends Persistent>, PersistentHelper>();

In Java, and for this particular case, I would give two tabs (or eight spaces) after the break, depending on whether tabs or spaces are used for indentation.

This is of course a personal preference and if your project has its own convention for line-wrapping then that is what you should follow whether you like it or not.

Nope, you can't abort an "each" without throwing an exception. You likely want a classic loop if you want the break to abort under a particular condition.

Alternatively, you could use a "find" closure instead of an each and return true when you would have done a break.

This example will abort before processing the whole list:

def a = [1, 2, 3, 4, 5, 6, 7]

a.find { 
    if (it > 5) return true // break
    println it  // do the stuff that you wanted to before break
    return false // keep looping
}

Prints

1
2
3
4
5

but doesn't print 6 or 7.

It's also really easy to write your own iterator methods with custom break behavior that accept closures:

List.metaClass.eachUntilGreaterThanFive = { closure ->
    for ( value in delegate ) {
        if ( value  > 5 ) break
        closure(value)
    }
}

def a = [1, 2, 3, 4, 5, 6, 7]

a.eachUntilGreaterThanFive {
    println it
}

Also prints:

1
2
3
4
5    

Refactoring the above methods and showing with the use:

private String[] languages = {"pt", "en", "es"};
private Integer indexOf(String[] arr, String str){
   for (int i = 0; i < arr.length; i++)
      if(arr[i].equals(str)) return i;
   return -1;
}
indexOf(languages, "en")

1. Data contract: It specifies that your entity class is ready for Serialization process.

2. Data members: It specifies that the particular field is part of the data contract and it can be serialized.

Here's the config for ISAPI_Rewrite 3:

I wrote two functions to flatten and unflatten a JSON object.

Flatten a JSON object:

var flatten = (function (isArray, wrapped) {
    return function (table) {
        return reduce("", {}, table);
    };

    function reduce(path, accumulator, table) {
        if (isArray(table)) {
            var length = table.length;

            if (length) {
                var index = 0;

                while (index < length) {
                    var property = path + "[" + index + "]", item = table[index++];
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            } else accumulator[path] = table;
        } else {
            var empty = true;

            if (path) {
                for (var property in table) {
                    var item = table[property], property = path + "." + property, empty = false;
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            } else {
                for (var property in table) {
                    var item = table[property], empty = false;
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            }

            if (empty) accumulator[path] = table;
        }

        return accumulator;
    }
}(Array.isArray, Object));

Performance:

1. It's faster than the current solution in Opera. The current solution is 26% slower in Opera.
2. It's faster than the current solution in Firefox. The current solution is 9% slower in Firefox.
3. It's faster than the current solution in Chrome. The current solution is 29% slower in Chrome.

Unflatten a JSON object:

function unflatten(table) {
    var result = {};

    for (var path in table) {
        var cursor = result, length = path.length, property = "", index = 0;

        while (index < length) {
            var char = path.charAt(index);

            if (char === "[") {
                var start = index + 1,
                    end = path.indexOf("]", start),
                    cursor = cursor[property] = cursor[property] || [],
                    property = path.slice(start, end),
                    index = end + 1;
            } else {
                var cursor = cursor[property] = cursor[property] || {},
                    start = char === "." ? index + 1 : index,
                    bracket = path.indexOf("[", start),
                    dot = path.indexOf(".", start);

                if (bracket < 0 && dot < 0) var end = index = length;
                else if (bracket < 0) var end = index = dot;
                else if (dot < 0) var end = index = bracket;
                else var end = index = bracket < dot ? bracket : dot;

                var property = path.slice(start, end);
            }
        }

        cursor[property] = table[path];
    }

    return result[""];
}

Performance:

1. It's faster than the current solution in Opera. The current solution is 5% slower in Opera.
2. It's slower than the current solution in Firefox. My solution is 26% slower in Firefox.
3. It's slower than the current solution in Chrome. My solution is 6% slower in Chrome.

Flatten and unflatten a JSON object:

Overall my solution performs either equally well or even better than the current solution.

Performance:

1. It's faster than the current solution in Opera. The current solution is 21% slower in Opera.
2. It's as fast as the current solution in Firefox.
3. It's faster than the current solution in Firefox. The current solution is 20% slower in Chrome.

Output format:

A flattened object uses the dot notation for object properties and the bracket notation for array indices:

1. {foo:{bar:false}} => {"foo.bar":false}
2. {a:[{b:["c","d"]}]} => {"a[0].b[0]":"c","a[0].b[1]":"d"}
3. [1,[2,[3,4],5],6] => {"[0]":1,"[1][0]":2,"[1][1][0]":3,"[1][1][1]":4,"[1][2]":5,"[2]":6}

In my opinion this format is better than only using the dot notation:

1. {foo:{bar:false}} => {"foo.bar":false}
2. {a:[{b:["c","d"]}]} => {"a.0.b.0":"c","a.0.b.1":"d"}
3. [1,[2,[3,4],5],6] => {"0":1,"1.0":2,"1.1.0":3,"1.1.1":4,"1.2":5,"2":6}

Advantages:

1. Flattening an object is faster than the current solution.
2. Flattening and unflattening an object is as fast as or faster than the current solution.
3. Flattened objects use both the dot notation and the bracket notation for readability.

Disadvantages:

1. Unflattening an object is slower than the current solution in most (but not all) cases.

The current JSFiddle demo gave the following values as output:

Nested : 132175 : 63
Flattened : 132175 : 564
Nested : 132175 : 54
Flattened : 132175 : 508

My updated JSFiddle demo gave the following values as output:

Nested : 132175 : 59
Flattened : 132175 : 514
Nested : 132175 : 60
Flattened : 132175 : 451

I'm not really sure what that means, so I'll stick with the jsPerf results. After all jsPerf is a performance benchmarking utility. JSFiddle is not.

For my point of view, First thing is to install soap into Centos

yum install php-soap

Second, see if the soap package exist or not

yum search php-soap

third, thus you must see some result of soap package you installed, now type a command in your terminal in the root folder for searching the location of soap for specific path

find -name soap.so

fourth, you will see the exact path where its installed/located, simply copy the path and find the php.ini to add the extension path,

usually the path of php.ini file in centos 6 is in

/etc/php.ini

fifth, add a line of code from below into php.ini file

extension='/usr/lib/php/modules/soap.so'

and then save the file and exit.

sixth run apache restart command in Centos. I think there is two command that can restart your apache ( whichever is easier for you )

service httpd restart

OR

apachectl restart

Lastly, check phpinfo() output in browser, you should see SOAP section where SOAP CLIENT, SOAP SERVER etc are listed and shown Enabled.

You just execute:

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

that would be for the current session, if you want to change permanently add it to any .bashrc, bash.bashrc, /etc/profile - whatever fits your system and user needs.

Note: This is for Linux. We'll make this clear for new coders. (` , ') Don't try to SET = these.

I had the same problem with small difference:

Exception was raised at the moment of flushing

It is a different stackoverflow issue. The brief explanation was a wrong response header setting:

response.setHeader("Content-Encoding", "gzip");

despite uncompressed response data content.

So the the connection was closed by the browser.

There is another way of controlling error handling that works well for loops. Create a string variable called here and use the variable to determine how a single error handler handles the error.

The code template is:

On error goto errhandler

Dim here as String

here = "in loop"
For i = 1 to 20 
    some code
Next i

afterloop:
here = "after loop"
more code

exitproc:    
exit sub

errhandler:
If here = "in loop" Then 
    resume afterloop
elseif here = "after loop" Then
    msgbox "An error has occurred" & err.desc
    resume exitproc
End if

Also you could use like below in C++.

int j=3;
int i=2;
for (; i<n && j<n ; j=j+2, i=i+2){
  // your code
}

With type-specific datetime string formatting (see nk9's answer using str.format().) in a Formatted string literal (since Python 3.6, 2016-12-23):

>>> import datetime
>>> f"{datetime.datetime.now():%Y-%m-%d}"
'2017-06-15'

The date/time format directives are not documented as part of the Format String Syntax but rather in date, datetime, and time's strftime() documentation. The are based on the 1989 C Standard, but include some ISO 8601 directives since Python 3.6.

When thinking about pointers, it helps to draw diagrams. A pointer is an arrow that points to an address in memory, with a label indicating the type of the value. The address indicates where to look and the type indicates what to take. Casting the pointer changes the label on the arrow but not where the arrow points.

d in main is a pointer to c which is of type char. A char is one byte of memory, so when d is dereferenced, you get the value in that one byte of memory. In the diagram below, each cell represents one byte.

-+----+----+----+----+----+----+-
 |    | c  |    |    |    |    | 
-+----+----+----+----+----+----+-
       ^~~~
       | char
       d

When you cast d to int*, you're saying that d really points to an int value. On most systems today, an int occupies 4 bytes.

-+----+----+----+----+----+----+-
 |    | c  | ?1 | ?2 | ?3 |    | 
-+----+----+----+----+----+----+-
       ^~~~~~~~~~~~~~~~~~~
       | int
       (int*)d

When you dereference (int*)d, you get a value that is determined from these four bytes of memory. The value you get depends on what is in these cells marked ?, and on how an int is represented in memory.

A PC is little-endian, which means that the value of an int is calculated this way (assuming that it spans 4 bytes): * ((int*)d) == c + ?1 * 28 + ?2 * 2¹6 + ?3 * 2²4. So you'll see that while the value is garbage, if you print in in hexadecimal (printf("%x\n", *n)), the last two digits will always be 35 (that's the value of the character '5').

Some other systems are big-endian and arrange the bytes in the other direction: * ((int*)d) == c * 2²4 + ?1 * 2¹6 + ?2 * 28 + ?3. On these systems, you'd find that the value always starts with 35 when printed in hexadecimal. Some systems have a size of int that's different from 4 bytes. A rare few systems arrange int in different ways but you're extremely unlikely to encounter them.

Depending on your compiler and operating system, you may find that the value is different every time you run the program, or that it's always the same but changes when you make even minor tweaks to the source code.

On some systems, an int value must be stored in an address that's a multiple of 4 (or 2, or 8). This is called an alignment requirement. Depending on whether the address of c happens to be properly aligned or not, the program may crash.

In contrast with your program, here's what happens when you have an int value and take a pointer to it.

int x = 42;
int *p = &x;

-+----+----+----+----+----+----+-
 |    |         x         |    | 
-+----+----+----+----+----+----+-
       ^~~~~~~~~~~~~~~~~~~
       | int
       p

The pointer p points to an int value. The label on the arrow correctly describes what's in the memory cell, so there are no surprises when dereferencing it.

As seen in this Angular example, there is a way to disable a button until the whole form is valid:

<button type="submit" [disabled]="!ngForm.valid">Submit</button>

just use -

if(!a) // if a is negative,undefined,null,empty value then...
{
    // do whatever
}
else {
    // do whatever
}

this works because of the == difference from === in javascript, which converts some values to "equal" values in other types to check for equality, as opposed for === which simply checks if the values equal. so basically the == operator know to convert the "", null, undefined to a false value. which is exactly what you need.

I think you are looking for:

git update-index --skip-worktree FILENAME

which ignore changes made local

Here's http://devblog.avdi.org/2011/05/20/keep-local-modifications-in-git-tracked-files/ more explanation about these solution!

to undo use:

git update-index --no-skip-worktree FILENAME

//if i input 9 it should go to 8?

You still have to work with the elements of the array. You will count 8 elements when looping through the array, but they are still going to be array(0) - array(7).

var username = $('#username').val();
var email= $('#email').val();
var password= $('#password').val();

It is technically approved that MD5 is faster than SHA256 so in just verifying file integrity it will be sufficient and better for performance.

While other answers were usable, this really helped me, so I am putting it also here.

From the documentation:

Instead of specifying a context, you can pass a single Dockerfile in the URL or pipe the file in via STDIN. To pipe a Dockerfile from STDIN:

$ docker build - < Dockerfile

With Powershell on Windows, you can run:

Get-Content Dockerfile | docker build -

When the build is done, run command:

docker image ls

You will see something like this:

REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE
<none>                     <none>              123456789        39 seconds ago      422MB

Copy your actual IMAGE ID and then run

docker run 123456789

Where the number at the end is the actual Image ID from previous step

If you do not want to remember the image id, you can tag your image by

docker tag 123456789 pavel/pavel-build

Which will tag your image as pavel/pavel-build

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

An easy way to format your domain objects to JSON is to use the Marshal Serializer. Then pass the data to json_encode and send the correct Content-Type header for your needs. If you are using a framework like Symfony, you don't need to take care of setting the headers manually. There you can use the JsonResponse.

For example the correct Content-Type for dealing with Javascript would be application/javascript.

Or if you need to support some pretty old browsers the safest would be text/javascript.

For all other purposes like a mobile app use application/json as the Content-Type.

Here is a small example:

<?php
...
$userCollection = [$user1, $user2, $user3];

$data = Marshal::serializeCollectionCallable(function (User $user) {
    return [
        'username' => $user->getUsername(),
        'email'    => $user->getEmail(),
        'birthday' => $user->getBirthday()->format('Y-m-d'),
        'followers => count($user->getFollowers()),
    ];
}, $userCollection);

header('Content-Type: application/json');
echo json_encode($data);

Joda-Time

Joda-Time 2.3 library offers already-debugged code for this chore.

Joad-Time includes three classes to represent a span of time: Period, Interval, and Duration. Period tracks a span as a number of months, days, hours, etc. (not tied to the timeline).

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.

// Specify a time zone rather than rely on default.
// Necessary to handle Daylight Saving Time (DST) and other anomalies.
DateTimeZone timeZone = DateTimeZone.forID( "America/Montreal" );

DateTimeFormatter formatter = DateTimeFormat.forPattern( "yy/MM/dd HH:mm:ss" ).withZone( timeZone ); 

DateTime dateTimeStart = formatter.parseDateTime( "11/03/14 09:29:58" );
DateTime dateTimeStop = formatter.parseDateTime( "11/03/14 09:33:43" );
Period period = new Period( dateTimeStart, dateTimeStop );

PeriodFormatter periodFormatter = PeriodFormat.getDefault();
String output = periodFormatter.print( period );

System.out.println( "output: " + output );

When run…

output: 3 minutes and 45 seconds

foreach (Control field in container.Controls)
            {
                if (field is TextBox)

In order to remove with wildcards, you'll need to write your own routine that handles this.

There are quite a few suggested approaches listed on this forum page.

Since there is not really an answer that works (selected answer disables dropdown), or overrides using javascript, here goes.

This is all html and css fix (uses two <a> tags):

<ul class="nav">
 <li class="dropdown dropdown-li">
    <a class="dropdown-link" href="http://google.com">Dropdown</a>
    <a class="dropdown-caret dropdown-toggle"><b class="caret"></b></a>
    <ul class="dropdown-menu">
        <li><a href="#">Link 1</a></li>
        <li><a href="#">Link 2</a></li>
    </ul>
 </li>
</ul>

Now here's the CSS you need.

.dropdown-li {
    display:inline-block !important;
}
.dropdown-link {
    display:inline-block !important; 
    padding-right:4px !important;
}
.dropdown-caret {
    display:inline-block !important; 
    padding-left:4px !important;
}

Assuming you will want the both <a> tags to highlight on hover of either one, you will also need to override bootstrap, you might play around with the following:

.nav > li:hover {
    background-color: #f67a47; /*hover background color*/
}
.nav > li:hover > a {
    color: white; /*hover text color*/
}
.nav > li:hover > ul > a {
    color: black; /*dropdown item text color*/
}

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

That's the wrong kind of question. The right question would be: "Which one is easier to understand for human readers of my code?"

If speed matters (later), don't ask, but measure. (And before that, measure whether optimizing this actually will make any noticeable difference.) Until then, write the code so that it is easiest to read.

Edit
Just to make this clear (although it already should have been): Breakthrough speedups usually come from things like using better algorithms, improving locality of data, reducing the use of dynamic memory, pre-computing results, etc. They rarely ever come from micro-optimizing single function calls, and where they do, they do so in very few places, which would only be found by careful (and time-consuming) profiling, more often than never they can be sped up by doing very non-intuitive things (like inserting noop statements), and what's an optimization for one platform is sometimes a pessimization for another (which is why you need to measure, instead of asking, because we don't fully know/have your environment).

Let me underline this again: Even in the few applications where such things matter, they don't matter in most places they're used, and it is very unlikely that you will find the places where they matter by looking at the code. You really do need to identify the hot spots first, because otherwise optimizing code is just a waste of time.

Even if a single operation (like computing the square of some value) takes up 10% of the application's execution time (which IME is quite rare), and even if optimizing it saves 50% of the time necessary for that operation (which IME is even much, much rarer), you still made the application take only 5% less time.
Your users will need a stopwatch to even notice that. (I guess in most cases anything under 20% speedup goes unnoticed for most users. And that is four such spots you need to find.)

If you want to remove all added files from git for commit

git reset

If you want to remove an individual file

git rm <file>

Make sure you have the contentSize property of the scroll view set to the correct size (ie, one large enough to encompass all your content.)

In case you use fastlane, additional flags can be passed with

gradle(
   ...
   flags: "{your flags}"

The key is "the order of the column should be the same"

Example:

create Table A (
    A_ID char(3) primary key,
    A_name char(10) primary key,
    A_desc desc char(50)
)

create Table B (
    B_ID char(3) primary key,
    B_A_ID char(3),
    B_A_Name char(10),
    constraint [Fk_B_01] foreign key (B_A_ID,B_A_Name) references A(A_ID,A_Name)
)

the column order on table A should be --> A_ID then A_Name; defining the foreign key should follow the same order as well.

    public class HomeController : Controller  
    {  
        public ActionResult Index()  
        {  
            ViewBag.TempValue = "Index Action called at HomeController";  
            return View();  
        }  

        [ChildActionOnly]  
        public ActionResult ChildAction(string param)  
        {  
            ViewBag.Message = "Child Action called. " + param;  
            return View();  
        }  
    }  


The code is initially invoking an Index action that in turn returns two Index views and at the View level it calls the ChildAction named “ChildAction”.

    @{
        ViewBag.Title = "Index";    
    }    
    <h2>    
        Index

In Bootstrap 3 (3.0.3) adding the "text-center" class to a td element works out of the box.

I.e., the following centers some text in a table cell:

<td class="text-center">some text</td>

actually, I found this in the code of a php based cms.

redirect('?module=blog', 0);

so it is possible. In this case, you are logged in at the admin level, so no harm no foul (I suppose). the first part is the url, and the second? I can't find any documentation for what the integer is for, but I guess it's either time, or data since it is attached to a form.

I, too, wanted to refresh a page after an event, and placing this in a better spot worked out well.

If you're using spring-boot-starter-parent in your pom, you simply add the following to your pom:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Then do your mvn package.

See this Spring docs page.

A very important aspect here is to mention that the directory structure has to be src/main/java/nameofyourpackage

I believe this can be solved by adding a project reference to Microsoft.EntityFrameworkCore.SqlServer.Design

Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

Microsoft.EntityFrameworkCore.SqlServer wasn't directly installed in my project, but the .Design package will install it anyway as a prerequisite.

This appears to fit what you are looking for: https://forums.oracle.com/forums/thread.jspa?threadID=2140801

Basically, you will need to use regular expressions as there appears to be nothing built into oracle for this.

I pulled out the example from the thread and converted it for your purposes. I suck at regex's, though, so that might need tweaked :)

    OkHttpClient client = new OkHttpClient();

    try {
        responses = client.newCall(request).execute();
    } catch (IOException e) {
        e.printStackTrace();
    }
    String jsonData = responses.body().string();
    JSONObject Jobject = new JSONObject(jsonData);
    JSONArray Jarray = Jobject.getJSONArray("employees");

    for (int i = 0; i < Jarray.length(); i++) {
        JSONObject object     = Jarray.getJSONObject(i);
    }
}

Example add to your columns:

JCol employees  = new employees();
colums.Setid(object.getInt("firstName"));
columnlist.add(lastName);           

If you want to build your solution for x86 and x64, your solution must be configured for both platforms. Actually you just have an Any CPU configuration.

How to check the available configuration for a project

To check the available configuration for a given project, open the project file (*.csproj for example) and look for a PropertyGroup with the right Condition.

If you want to build in Release mode for x86, you must have something like this in your project file:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
  ...
</PropertyGroup>

May 2020 Here's a simple solution i found and it will resolve for all of my projects ,on windows if your project is somewhere inside c: directory , create new file .jshintrc and save it in C directory open this .jshintrc file and write { "esversion": 6} and that's it. the warnings should go away , same will work in d directory

yes you can also enable this setting for the specific project only by same creating a .jshintrc file in your project's root and adding { "esversion": 6}

It sounds like it's just a compiler warning.

Usage of scanf_s prevents possible buffer overflow.
See: http://code.wikia.com/wiki/Scanf_s

Good explanation as to why scanf can be dangerous: Disadvantages of scanf

So as suggested, you can try replacing scanf with scanf_s or disable the compiler warning.

Just Simply use

use css code: text-transform: uppercase;

Microsoft Docs stands for:

Once an exception is thrown, part of the information it carries is the stack trace. The stack trace is a list of the method call hierarchy that starts with the method that throws the exception and ends with the method that catches the exception. If an exception is re-thrown by specifying the exception in the throw statement, the stack trace is restarted at the current method and the list of method calls between the original method that threw the exception and the current method is lost. To keep the original stack trace information with the exception, use the throw statement without specifying the exception.

The following code will compare each item with other list of items using contains() method.Length of for loop must be bigger size() of bigger list then only it will compare all the values of both list.

List<String> str = new ArrayList<String>();
str.add("first");
str.add("second");
str.add("third");
List<String> str1 = new ArrayList<String>();
str1.add("first");
str1.add("second");
str1.add("third1");
for (int i = 0; i<str1.size(); i++)
{
System.out.println(str.contains(str1.get(i)));
}

Output is true true false

Thing is an inner class with an automatic connection to an instance of Hello. You get a compile error because there is no instance of Hello for it to attach to. You can fix it most easily by changing it to a static nested class which has no connection:

Perhaps you misunderstand the way FileUpload works.

When you upload a file, it is effectively being transferred from the client's computer to the server hosting your application. If you're developing the application, most times, both client and server are the same machine (your computer). Once the application is deployed however, there could be any number of clients connecting to the server, each uploading a different file.

Knowing the full path of the file on the client's computer usually isn't necessary - you'll often want to do something with the file contents. Your examples seem like ASP.NET C#, so I'm guessing you're using the FileUpload control. You can get at the uploaded file's contents by reading the raw stream (FileUpload.PostedFile.InputStream) or by saving the file first (FileUpload.PostedFile.SaveAs), then accessing the saved file. It's your responsibility to save the file, if you want it to be accessible after the current request - if you don't, ASP.NET deletes it.

One more thing - don't forget to set the enctype property on your form to "multipart/form-data". If you don't, the client's browser won't send the file, and you'll spend quite a few minutes wondering what went wrong.

Just pressing F5 is not always working.

why?

Because your ISP is also caching web data for you.

Solution: Force Refresh.

Force refresh your browser by pressing CTRL + F5 in Firefox or Chrome to clear ISP cache too, instead of just pressing F5

You then can see 200 response instead of 304 in the browser F12 developer tools network tab.

Another trick is to add question mark ? at the end of the URL string of the requested page:

http://localhost:52199/Customers/Create?

The question mark will ensure that the browser refresh the request without caching any previous requests.

Additionally in Visual Studio you can set the default browser to Chrome in Incognito mode to avoid cache issues while developing, by adding Chrome in Incognito mode as default browser, see the steps (self illustrated):

I also had that error. But none of the above solved the issue. So i uninstalled and again installed the composer. Then i did composer update. and the problem was fixed.

NestedScrollView

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.

https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html

ScrollView

Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display. A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects

https://developer.android.com/reference/android/widget/ScrollView.html

As others have answered, the mysqli API can execute multi-queries with the msyqli_multi_query() function.

For what it's worth, PDO supports multi-query by default, and you can iterate over the multiple result sets of your multiple queries:

$stmt = $dbh->prepare("
    select sql_calc_found_rows * from foo limit 1 ; 
    select found_rows()");
$stmt->execute();
do {
  while ($row = $stmt->fetch()) {
    print_r($row);
  }
} while ($stmt->nextRowset());

However, multi-query is pretty widely considered a bad idea for security reasons. If you aren't careful about how you construct your query strings, you can actually get the exact type of SQL injection vulnerability shown in the classic "Little Bobby Tables" XKCD cartoon. When using an API that restrict you to single-query, that can't happen.

Here is the perfect example of downloading a file using javaScript.

Usage: download_file(fileURL, fileName);

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

Instead of

return new ResponseEntity<JSONObject>(entities, HttpStatus.OK);

try

return new ResponseEntity<List<JSONObject>>(entities, HttpStatus.OK);

Try to using application/* instead. And use JSON.maybeJson() to check the data structure in the controller.

Jack's answer is perfectly working for click event while longClick is considering is as menu button click.

By the way, if anyone is wondering how to do via kotlin,

class HomeButtonReceiver(private var context: Context,private var listener: OnHomeButtonClickListener) {
    private val mFilter: IntentFilter = IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)
    private var mReceiver: InnerReceiver = InnerReceiver()

    fun startWatch() {
        context.registerReceiver(mReceiver, mFilter)
    }

    fun stopWatch() {
        context.unregisterReceiver(mReceiver)
    }

    inner class InnerReceiver: BroadcastReceiver() {
        private val systemDialogReasonKey = "reason"
        private val systemDialogReasonHomeKey = "homekey"
        override fun onReceive(context: Context?, intent: Intent?) {
            val action = intent?.action
            if (action == Intent.ACTION_CLOSE_SYSTEM_DIALOGS) {
                val reason = intent.getStringExtra(systemDialogReasonKey)
                if (reason != null && reason == systemDialogReasonHomeKey) {
                    listener.onHomeButtonClick()
                }
            }
        }
    } 
}

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

I know I'm coming to this late, but what the heck.

I've got almost the exact same code as Kris, using just one Activity but with 2 different layouts/views, and I want to switch between the layouts at will.

As a test, I added 2 menu options, each one switches the view:

public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
            case R.id.item1:
                setContentView(R.layout.main);
                return true;
            case R.id.item2:
                setContentView(R.layout.alternate);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

Note, I've got one Activity class. This works perfectly. So I have no idea why people are suggesting using different Activities / Intents. Maybe someone can explain why my code works and Kris's didn't.

You can't - a set is unordered, so there's no index provided. You'll have to declare an int, as you say. Just remember that the next time you call keySet() you won't necessarily get the results in the same order.

HttpClient is a new API that came with 4.3, it has updated API's with support for progress events, json deserialization by default, Interceptors and many other great features. See more here https://angular.io/guide/http

Http is the older API and will eventually be deprecated.

Since their usage is very similar for basic tasks I would advise using HttpClient since it is the more modern and easy to use alternative.

Expanding on Mark's suggestions...

Method 3

Implement "deep" change detection on the model. The advantages primarily involve the avoidance of incorporating user interface aspects into the component; this also catches programmatic changes made to the model. That said, it would require extra work to implement such things as debouncing as suggested by Thierry, and this will also catch your own programmatic changes, so use with caution.

export class App implements DoCheck {
  person = { first: "Sally", last: "Jones" };
  oldPerson = { ...this.person }; // ES6 shallow clone. Use lodash or something for deep cloning

  ngDoCheck() {
    // Simple shallow property comparison - use fancy recursive deep comparison for more complex needs
    for (let prop in this.person) {
      if (this.oldPerson[prop] !==  this.person[prop]) {
        console.log(`person.${prop} changed: ${this.person[prop]}`);
        this.oldPerson[prop] = this.person[prop];
      }
    }
  }

For everyone here seeking a crazy solution, just simply try

in any tag. I've tested into td's and a's and it pretty works.

Here's the correct code for your service:

myApp.service('userService', [
  '$http', '$q', '$rootScope', '$location', function($http, $q, $rootScope, $location) {

    var user = {
      access: false
    };

    var me = this;

    this.initialized = false;
    this.isAuthenticated = function() {

      var deferred = $q.defer();
      user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      deferred.resolve(user);
      me.initialized = true;

      return deferred.promise;
    };
  }
]);

Then you controller should align accordingly:

myApp.run([
  '$rootScope', 'userService', function($rootScope, userService) {
    return userService.isAuthenticated().then(function(user) {
      if (user) {
        // You have access to the object you passed in the service, not to the response.
        // You should either put response.data on the user or use a different property.
        return $rootScope.$broadcast('login', user.email);  
      } else {
        return userService.logout();
      }
    });
  }
]);

Few points to note about the service:

• Expose in a service only what needs to be exposed. User should be kept internally and be accessed by getters only.

• When in functions, use 'me' which is the service to avoid edge cases of this with javascript.

• I guessed what initialized was meant to do, feel free to correct me if I guessed wrong.

Assuming that you didn't set a precision initially, it's assumed to be the maximum (38). You're reducing the precision because you're changing it from 38 to 14.

The easiest way to handle this is to rename the column, copy the data over, then drop the original column:

alter table EVAPP_FEES rename column AMOUNT to AMOUNT_OLD;

alter table EVAPP_FEES add AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_OLD;

alter table EVAPP_FEES drop column AMOUNT_OLD;

If you really want to retain the column ordering, you can move the data twice instead:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

<!DOCTYPE html>
<html>
<head></head>
<body>
<div style=" background-color: #00000088"> Hi there </div>
<!-- #00 would be r, 00 would be g, 00 would be b, 88 would be a. -->
</body>
</html>

including 4 sets of numbers would make it rgba, not cmyk, but either way would work (rgba= 00000088, cmyk= 0%, 0%, 0%, 50%)

A practical explanation: By default, <p> </p> will add line breaks before and after the enclosed text (so it creates a paragraph). <span> does not do this, that is why it is called inline.

Hi If you want to install android studio on ubuntu you shoudl first have Java JDk on ubuntu. Installing Java SDK

First you have to install Oracle on Java 7 (JDK and JRE)

Download Java SDK 32 or 64 bit depending upon your version.

java sdk on ubuntu

Then extract the file in the /tmp folder.Al dialogue box will pop up, click on replace all.An error will also pop out click close.

Go to tmp folder,a new folder name jdk and version must be created.right click on the folder and then click on rename and copy the name of the folder.

Also read How to Install Genymotion on Ubuntu First write this command and click enter.

install android sdk on ubuntu linux

sudo su

Then write this command and press enter

if [ ! -d '/usr/lib/jvm' ]; then mkdir /usr/lib/jvm; fi

Paste this command

mv /tmp/jdk1.8* /usr/lib/jvm/  

jdk1.8* = replace it with the name of the extracted folder in this example =jdk1.8.0_05

and press enter

sdk install linux

java,javac,jar,javaws = we have to replace these

update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8*/bin/java 1065
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8*/bin/javac 1065
update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.8*/bin/jar 1065
update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.8*/bin/javaws 1065
update-alternatives --config java
java -version

webRTC or websockets? Why not use both.

When building a video/audio/text chat, webRTC is definitely a good choice since it uses peer to peer technology and once the connection is up and running, you do not need to pass the communication via a server (unless using TURN).

When setting up the webRTC communication you have to involve some sort of signaling mechanism. Websockets could be a good choice here, but webRTC is the way to go for the video/audio/text info. Chat rooms is accomplished in the signaling.

But, as you mention, not every browser supports webRTC, so websockets can sometimes be a good fallback for those browsers.

Read-Host is a simple option for getting string input from a user.

$name = Read-Host 'What is your username?'

To hide passwords you can use:

$pass = Read-Host 'What is your password?' -AsSecureString

To convert the password to plain text:

[Runtime.InteropServices.Marshal]::PtrToStringAuto(
    [Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass))

As for the type returned by $host.UI.Prompt(), if you run the code at the link posted in @Christian's comment, you can find out the return type by piping it to Get-Member (for example, $results | gm). The result is a Dictionary where the key is the name of a FieldDescription object used in the prompt. To access the result for the first prompt in the linked example you would type: $results['String Field'].

To access information without invoking a method, leave the parentheses off:

PS> $Host.UI.Prompt

MemberType          : Method
OverloadDefinitions : {System.Collections.Generic.Dictionary[string,psobject] Pr
                    ompt(string caption, string message, System.Collections.Ob
                    jectModel.Collection[System.Management.Automation.Host.Fie
                    ldDescription] descriptions)}
TypeNameOfValue     : System.Management.Automation.PSMethod
Value               : System.Collections.Generic.Dictionary[string,psobject] Pro
                    mpt(string caption, string message, System.Collections.Obj
                    ectModel.Collection[System.Management.Automation.Host.Fiel
                    dDescription] descriptions)
Name                : Prompt
IsInstance          : True

$Host.UI.Prompt.OverloadDefinitions will give you the definition(s) of the method. Each definition displays as <Return Type> <Method Name>(<Parameters>).

Typically you see this error after you have already done a redirect and then try to output some more data to the output stream. In the cases where I have seen this in the past, it is often one of the filters that is trying to redirect the page, and then still forwards through to the servlet. I cannot see anything immediately wrong with the servlet, so you might want to try having a look at any filters that you have in place as well.

Edit: Some more help in diagnosing the problem…

The first step to diagnosing this problem is to ascertain exactly where the exception is being thrown. We are assuming that it is being thrown by the line

getServletConfig().getServletContext()
                  .getRequestDispatcher("/GroupCopiedUpdt.jsp")
                  .forward(request, response);

But you might find that it is being thrown later in the code, where you are trying to output to the output stream after you have tried to do the forward. If it is coming from the above line, then it means that somewhere before this line you have either:

1. output data to the output stream, or
2. done another redirect beforehand.

Good luck!

For me the problem was caused by a gradle.properties file in the list of Gradle scripts. It showed as gradle.properties (global) and refered to a file in C:\users\.gradle\gradle.properties. I right-clicked on it and selected delete from the menu to delete it. It deleted the file from the hard disk and my project now builds and runs. I guess that the global file was overwriting something that was used to locate the package android.support

This is a supplement answer related to the OP:

An easy and reliable solution to add Javadocs comments in Eclipse:

1. Go to Help > Eclipse Marketplace....
2. Find "JAutodoc".
3. Install it and restart Eclipse.

To use this tool, right-click on class and click on JAutodoc.

This should work:

[ int(x) for x in "40 1".split(" ") ]

Maybe you can script/control winscp?

Update: winscp now has a .NET library available as a nuget package that supports SFTP, SCP, and FTPS

This works fine:

struct node *addNode(node *head, int value) {
    node *newNode = (node *) malloc(sizeof(node));
    newNode->value = value;
    newNode->next = NULL;

    if (head == NULL) {
        // Add at the beginning
        head = newNode;
    } else {
        node *current = head;

        while (current->next != NULL) {
            current = current->next;
        };

        // Add at the end
        current->next = newNode;
    }

    return head;
}

Example usage:

struct node *head = NULL;

for (int currentIndex = 1; currentIndex < 10; currentIndex++) {
    head = addNode(head, currentIndex);
}

There is a simple solution, So when you run Object.keys(Enum) that gonna give you a Array of Values and Keys, in first slice Values and in the second one keys, so why we don't just return the second slice, this code below works for me.

enum Enum {
   ONE,
   TWO,
   THREE,
   FOUR,
   FIVE,
   SIX,
   SEVEN
}
const keys = Object.keys(Enum); 
console.log(keys.slice(keys.length / 2));

Using parenthesis in a programming language or a scripting language usually means that it is a function.

However $_COOKIE in php is not a function, it is an Array. To access data in arrays you use square braces ('[' and ']') which symbolize which index to get the data from. So by doing $_COOKIE['test'] you are basically saying: "Give me the data from the index 'test'.

Now, in your case, you have two possibilities: (1) either you want to see if it is false--by looking inside the cookie or (2) see if it is not even there.

For this, you use the isset function which basically checks if the variable is set or not.

Example

if ( isset($_COOKIE['test'] ) )

And if you want to check if the value is false and it is set you can do the following:

if ( isset($_COOKIE['test']) && $_COOKIE['test'] == "false" )

One thing that you can keep in mind is that if the first test fails, it wont even bother checking the next statement if it is AND ( && ).

And to explain why you actually get the error "Function must be a string", look at this page. It's about basic creation of functions in PHP, what you must remember is that a function in PHP can only contain certain types of characters, where $ is not one of these. Since in PHP $ represents a variable.

A function could look like this: _myFunction _myFunction123 myFunction and in many other patterns as well, but mixing it with characters like $ and % will not work.

There is one very interesting application by Stéphane Sudre which does all of this for you, is scriptable / supports building from the command line, has a super nice GUI and is FREE. Sad thing is: it's called "Packages" which makes it impossible to find in google.

I wished I had known about it before I started handcrafting my own scripts.

You can assign default parameter values inline when you first create the mixin:

@mixin clearfix($width: 'auto') {

  @if $width == 'auto' {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}
