UPDATE: As mentioned by Richard Grimes in my cited post, @Iain and @Dmitry Lobanov, my answer is right in theory but wrong in practice.

As I should have remembered from countless books, etc., while one sets these properties using the [assembly: XXXAttribute], they get highjacked by the compiler and placed into the VERSIONINFO resource.

For the above reason, you need to use the approach in @Xiaofu's answer as the attributes are stripped after the signal has been extracted from them.

public static string GetProductVersion()
{
  var attribute = (AssemblyVersionAttribute)Assembly
    .GetExecutingAssembly()
    .GetCustomAttributes( typeof(AssemblyVersionAttribute), true )
    .Single();
   return attribute.InformationalVersion;
}

(From http://bytes.com/groups/net/420417-assemblyversionattribute - as noted there, if you're looking for a different attribute, substitute that into the above)

Are you strong-naming your assemblies? In that case it is not a good idea to auto-increment your build number because with every new build number you will also have to update all your references.

It's worth noting some other things:

1. As shown in Windows Explorer Properties dialog for the generated assembly file, there are two places called "File version". The one seen in the header of the dialog shows the AssemblyVersion, not the AssemblyFileVersion.

   In the Other version information section, there is another element called "File Version". This is where you can see what was entered as the AssemblyFileVersion.

2. AssemblyFileVersion is just plain text. It doesn't have to conform to the numbering scheme restrictions that AssemblyVersion does (<build> < 65K, e.g.). It can be 3.2.<release tag text>.<datetime>, if you like. Your build system will have to fill in the tokens.

   Moreover, it is not subject to the wildcard replacement that AssemblyVersion is. If you just have a value of "3.0.1.*" in the AssemblyInfo.cs, that is exactly what will show in the Other version information->File Version element.

3. I don't know the impact upon an installer of using something other than numeric file version numbers, though.

We had the same issue, using Plesk Onyx 17. Instead of messing up with rights etc., solution was to add nginx user into psacln group, in which all the other domain owners (users) were:

usermod -aG psacln nginx

Now nginx has rights to access .htaccess or any other file necessary to properly show the content.

On the other hand, also make sure that Apache is in psaserv group, to serve static content:

usermod -aG psaserv apache

And don't forget to restart both Apache and Nginx in Plesk after! (and reload pages with Ctrl-F5)

I would also note there are two ways to get the number of ms in the time point. I'm not sure which one is better, I've benchmarked them and they both have the same performance, so I guess it's a matter of preference. Perhaps Howard could chime in:

auto now = system_clock::now();

//Cast the time point to ms, then get its duration, then get the duration's count.
auto ms = time_point_cast<milliseconds>(now).time_since_epoch().count();

//Get the time point's duration, then cast to ms, then get its count.
auto ms = duration_cast<milliseconds>(tpBid.time_since_epoch()).count();

The first one reads more clearly in my mind going from left to right.

Looks like HighChart 2.2.0 has resolved this issue. I tried it here with the same code you have, and the first series is hidden now. Could you try it with HighChart 2.2.0?

You can just convert a full outer join, e.g.

SELECT fields
FROM firsttable
FULL OUTER JOIN secondtable ON joincondition

into:

SELECT fields
FROM firsttable
LEFT JOIN secondtable ON joincondition
UNION ALL
SELECT fields (replacing any fields from firsttable with NULL)
FROM secondtable
WHERE NOT EXISTS (SELECT 1 FROM firsttable WHERE joincondition)

Or if you have at least one column, say foo, in firsttable that is NOT NULL, you can do:

SELECT fields
FROM firsttable
LEFT JOIN secondtable ON joincondition
UNION ALL
SELECT fields
FROM firsttable
RIGHT JOIN secondtable ON joincondition
WHERE firsttable.foo IS NULL

I was recieving the same error when I was tring to call an object element by using another objects return value like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->$this->array1->country;// Error line

The above code was throwing the error and I tried many ways to fix it like; calling this part $this->array1->country in another function as return value, (string), taking it into quotations etc. I couldn't even find the solution on the web then i realised that the solution was very simple. All you have to do it wrap it with curly brackets and that allows you to target an object with another object's element value. like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->{$this->array1->country};

If anyone facing the same and couldn't find the answer, I hope this can help because i spend a night for this simple solution =)

Try FileReader, this reader is meant to read stream of character, while FileInputStream is meant to read raw data.

From the Javadoc:

FileReader is meant for reading streams of characters. For reading streams of raw bytes, consider using a FileInputStream.

Since you wanna read a log file, FileReader is the class to use IMO.

EDIT: As pointed out in the comments, this is a much simpler version: Arrays.stream(stringArray).mapToInt(Integer::parseInt).toArray() This way we can skip the whole conversion to and from a list.

I found another one line solution, but it's still pretty slow (takes about 100 times longer than a for cycle - tested on an array of 6000 0's)

String[] stringArray = ...
int[] out= Arrays.asList(stringArray).stream().map(Integer::parseInt).mapToInt(i->i).toArray();

What this does:

1. Arrays.asList() converts the array to a List
2. .stream converts it to a Stream (needed to perform a map)
3. .map(Integer::parseInt) converts all the elements in the stream to Integers
4. .mapToInt(i->i) converts all the Integers to ints (you don't have to do this if you only want Integers)
5. .toArray() converts the Stream back to an array

Using ImageMagick, this is very similar to hackerb9 code and result, but is a little simpler command line. It does assume that the top left pixel is the background color. I just flood fill the background with transparency, then select the alpha channel and blur it and remove half of the blurred area using -level 50x100%. Then turn back on all the channels and flatten it against the brown color. The -blur 0x1 -level 50x100% acts to antialias the boundaries of the alpha channel transparency. You can adjust the fuzz value, blur amount and the -level 50% value to change the degree of antialiasing.

convert logo: -fuzz 25% -fill none -draw "matte 0,0 floodfill" -channel alpha -blur 0x1 -level 50x100% +channel -background saddlebrown -flatten result.jpg

Before you proceed to conda update --all command, first update conda with conda update conda command if you haven't update it for a long time. It happent to me (Python 2.7.13 on Anaconda 64 bits).

Try the code mentioned below

public static void main(String[] args) {
    int smallest=0; int large=0; int num;
    System.out.println("enter the number");
    Scanner input=new Scanner(System.in);
    int n=input.nextInt();
    num=input.nextInt();
    smallest = num;
    for(int i=0;i<n-1;i++)
        {
            num=input.nextInt();
            if(num<smallest)
            {
                smallest=num;
            }
        }
        System.out.println("the smallest is:"+smallest);
}

Try using:

console.log($("#"+d));

This will remove the extra quotes you were using.

Simplest solution for sending email from Organizational account in Office 365:

from O365 import Message

html_template =     """ 
            <html>
            <head>
                <title></title>
            </head>
            <body>
                    {}
            </body>
            </html>
        """

final_html_data = html_template.format(df.to_html(index=False))

o365_auth = ('sender_username@company_email.com','Password')
m = Message(auth=o365_auth)
m.setRecipients('receiver_username@company_email.com')
m.setSubject('Weekly report')
m.setBodyHTML(final_html_data)
m.sendMessage()

here df is a dataframe converted to html Table, which is being injected to html_template

You can apply the when method to your array:

var arr = [ /* Deferred objects */ ];

$.when.apply($, arr);

How do you work with an array of jQuery Deferreds?

jQuery doesn't have any Date utilities at all. If you don't use any additional libraries, the usual way is to create a JavaScript Date object and then extract the data from it and format it yourself.

For creating the Date object you can either make sure that your date string in the JSON is in a form that Date understands, which is IETF standard (which is basically RFC 822 section 5). So if you have the chance to change your JSON, that would be easiest. (EDIT: Your format may actually work the way it is.)

If you can't change your JSON, then you'll need to parse the string yourself and get day, mouth, year, hours, minutes and seconds as integers and create the Date object with that.

Once you have your Date object you'll need to extract the data you need and format it:

   var myDate = new Date("4 Feb 2011, 19:00:00");
   var hours = myDate.getHours();
   var am = true;
   if (hours > 12) {
      am = false;
      hours -= 12;
   } else (hours == 12) {
      am = false;
   } else (hours == 0) {
      hours = 12;
   }

   var minutes = myDate.getMinutes();
   alert("It is " + hours + " " + (am ? "a.m." : "p.m.") + " and " + minutes + " minutes".);

I came accross the same problem and solved.

As said before you need to create your custom WebViewClient and override the shouldInterceptRequest method.

WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request)

That method should issue a webView.loadUrl while returning an "empty" WebResourceResponse.

Something like this:

@Override
public boolean shouldInterceptRequest(WebView view, WebResourceRequest request) {

    // Check for "recursive request" (are yor header set?)
    if (request.getRequestHeaders().containsKey("Your Header"))
        return null;

    // Add here your headers (could be good to import original request header here!!!)
    Map<String, String> customHeaders = new HashMap<String, String>();
    customHeaders.put("Your Header","Your Header Value");
    view.loadUrl(url, customHeaders);

    return new WebResourceResponse("", "", null);
}

Based on the layout you gave you can use float left property in css.

You can do the descending sort of a user-defined class this way overriding the compare() method,

Collections.sort(unsortedList,new Comparator<Person>() {
    @Override
    public int compare(Person a, Person b) {
        return b.getName().compareTo(a.getName());
    }
});

Or by using Collection.reverse() to sort descending as user Prince mentioned in his comment.

And you can do the ascending sort like this,

Collections.sort(unsortedList,new Comparator<Person>() {
    @Override
    public int compare(Person a, Person b) {
        return a.getName().compareTo(b.getName());
    }
});

Replace the above code with a Lambda expression(Java 8 onwards) we get concise:

Collections.sort(personList, (Person a, Person b) -> b.getName().compareTo(a.getName()));

As of Java 8, List has sort() method which takes Comparator as parameter(more concise) :

personList.sort((a,b)->b.getName().compareTo(a.getName()));

Here a and b are inferred as Person type by lambda expression.

This is the best method to download and view PDF file.You can just call it from anywhere as like

try it. it will works, enjoy

You can check with String == null

This works for me

    String foo = null;
    if(foo == null){
        System.out.println("String is null");
    }

Modification of @Ilya_Gazman answer

    private void callJavaScript(WebView view, String methodName, Object...params){
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("javascript:try{");
        stringBuilder.append(methodName);
        stringBuilder.append("(");
        String separator = "";
        for (Object param : params) {               
            stringBuilder.append(separator);
            separator = ",";
            if(param instanceof String){
                stringBuilder.append("'");
            }
                stringBuilder.append(param.toString().replace("'", "\\'"));
            if(param instanceof String){
                stringBuilder.append("'");
            }

        }
        stringBuilder.append(")}catch(error){console.error(error.message);}");
        final String call = stringBuilder.toString();
        Log.i(TAG, "callJavaScript: call="+call);


        view.loadUrl(call);
    }

will correctly create JS calls e.g.

callJavaScript(mBrowser, "alert", "abc", "def");
//javascript:try{alert('abc','def')}catch(error){console.error(error.message);}
callJavaScript(mBrowser, "alert", 1, true, "abc");
//javascript:try{alert(1,true,'abc')}catch(error){console.error(error.message);}

Note that objects will not be passed correctly - but you can serialize them before passing as an argument.

Also I've changed where the error goes, I've diverted it to the console log which can be listened by:

    webView.setWebChromeClient(new CustomWebChromeClient());

and client

class CustomWebChromeClient extends WebChromeClient {
    private static final String TAG = "CustomWebChromeClient";

    @Override
    public boolean onConsoleMessage(ConsoleMessage cm) {
        Log.d(TAG, String.format("%s @ %d: %s", cm.message(),
                cm.lineNumber(), cm.sourceId()));
        return true;
    }
}

From the docs:

"a UNIQUE index permits multiple NULL values for columns that can contain NULL"

This applies to all engines but BDB.

In some extreme cases, your only way around recurring build failures is by running:

docker system prune

The command will ask you for your confirmation:

WARNING! This will remove:
    - all stopped containers
    - all volumes not used by at least one container
    - all networks not used by at least one container
    - all images without at least one container associated to them
Are you sure you want to continue? [y/N]

This is of course not a direct answer to the question, but might save some lives... It did save mine.

Just restarting the visual Studio would do the job. As I did this and it worked like a charm

Have you tried the "Publish" method? You just right click on the project file in the solution explorer and select "Publish" from the pop-up menu. This creates an installer in a few very simple steps.

You can do more configuration of the installer from the Publish tab in the project properties window.

NB: This method only works for WPF & Windows Forms apps.

Try this

<div style="background: linear-gradient( rgba(0, 0, 0, 0.7), rgba(0, 0, 0, 0.7) ), url(/image.png);background-repeat: no-repeat; background-position: center;"> </div>

I like to add this method, if you are using an edit form, you can use this code to save the changes in your update(Request $request, $id) function:

$post = Post::find($id);    
$post->fill($request->input())->save();

keep in mind that you have to name your inputs with the same column name. The fill() function will do all the work for you :)

Maybe you mean like this? I like to make an object and use Format-Table:

> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table

Name                                                                        Age Info
----                                                                        --- ----
Joe                                                                          32  something about him

This will put all objects you have in the array in columns according to their properties.

Tip: Using -auto sizes the table better

> $array | Format-Table -Auto

Name Age Info
---- --- ----
Joe   32 something about him

You can also specify which properties you want in the table. Just separate each property name with a comma:

> $array | Format-Table Name, Age -Auto

Name Age
---- ---
Joe   32

If you need to use the vector over and over again and your current code declares it repeatedly within your loop or on every function call, it is likely that you will run out of memory. I suggest that you declare it outside, pass them as pointers in your functions and use:

my_arr.resize()

This way, you keep using the same memory sequence for your vectors instead of requesting for new sequences every time. Hope this helped. Note: resizing it to different sizes may add random values. Pass an integer such as 0 to initialise them, if required.

In my case, I am Returning JSON Object as

{"data":"","message":"Attendance Saved Successfully..!!!","status":"success"}

Resolved by changing it as

{"data":{},"message":"Attendance Saved Successfully..!!!","status":"success"}

Here data is a sub JsonObject and it should starts from { not ""

This code works for me to get all links of the document

var links=document.getElementsByTagName('a'), hrefs = [];
for (var i = 0; i<links.length; i++)
{   
    hrefs.push(links[i].href);
}

Interpretation of date strings into datetime and datetime2 can be different too, when using non-US DATEFORMAT settings. E.g.

set dateformat dmy
declare @d datetime, @d2 datetime2
select @d = '2013-06-05', @d2 = '2013-06-05'
select @d, @d2

This returns 2013-05-06 (i.e. May 6) for datetime, and 2013-06-05 (i.e. June 5) for datetime2. However, with dateformat set to mdy, both @d and @d2 return 2013-06-05.

The datetime behavior seems at odds with the MSDN documentation of SET DATEFORMAT which states: Some character strings formats, for example ISO 8601, are interpreted independently of the DATEFORMAT setting. Obviously not true!

Until I was bitten by this, I'd always thought that yyyy-mm-dd dates would just be handled right, regardless of the language / locale settings.

I was having the same problem while making a POST request from Postman and later I could solve the problem by setting a custom Content-Type with a boundary value set along with it like this.

I thought people can run into similar problem and hence, I'm sharing my solution.

To change status bar color use setStatusBarColor(int color). According the javadoc, we also need set some flags on the window.

Working snippet of code:

Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.setStatusBarColor(ContextCompat.getColor(activity, R.color.example_color));

Keep in mind according Material Design guidelines status bar color and action bar color should be different:

• ActionBar should use primary 500 color
• StatusBar should use primary 700 color

Look at the screenshot below:

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

I just want to add some point to all that was listed.

With Reflection API you can write universal toString() method for any object.

It is useful at debugging.

Here is some example:

class ObjectAnalyzer {

   private ArrayList<Object> visited = new ArrayList<Object>();

   /**
    * Converts an object to a string representation that lists all fields.
    * @param obj an object
    * @return a string with the object's class name and all field names and
    * values
    */
   public String toString(Object obj) {
      if (obj == null) return "null";
      if (visited.contains(obj)) return "...";
      visited.add(obj);
      Class cl = obj.getClass();
      if (cl == String.class) return (String) obj;
      if (cl.isArray()) {
         String r = cl.getComponentType() + "[]{";
         for (int i = 0; i < Array.getLength(obj); i++) {
            if (i > 0) r += ",";
            Object val = Array.get(obj, i);
            if (cl.getComponentType().isPrimitive()) r += val;
            else r += toString(val);
         }
         return r + "}";
      }

      String r = cl.getName();
      // inspect the fields of this class and all superclasses
      do {
         r += "[";
         Field[] fields = cl.getDeclaredFields();
         AccessibleObject.setAccessible(fields, true);
         // get the names and values of all fields
         for (Field f : fields) {
            if (!Modifier.isStatic(f.getModifiers())) {
               if (!r.endsWith("[")) r += ",";
               r += f.getName() + "=";
               try {
                  Class t = f.getType();
                  Object val = f.get(obj);
                  if (t.isPrimitive()) r += val;
                  else r += toString(val);
               } catch (Exception e) {
                  e.printStackTrace();
               }
            }
         }
         r += "]";
         cl = cl.getSuperclass();
      } while (cl != null);

      return r;
   }    
}

I think you have to make some required configuration to start and run IE properly. You can find the guide at: https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver

There is another case where this status will be returned: if the Jackson mapper cannot figure out how to serialize your bean. For example, if you have two accessor methods for the same boolean property, isFoo() and getFoo().

removed getFoo() and put isFoo(). it worked for me.

Use process.wait() after you call process.communicate().
For example:

import subprocess

process = subprocess.Popen(['ipconfig', '/all'], stderr=subprocess.PIPE, stdout=subprocess.PIPE)
stdout, stderr = process.communicate()
exit_code = process.wait()
print(stdout, stderr, exit_code)

(This is for the benefit of others who may refer)

You can simply use cin and a char array. The cin input is delimited by the first whitespace it encounters.

#include<iostream>
using namespace std;

main()
{
    char word[50];
    cin>>word;
    while(word){
        //Do stuff with word[]
        cin>>word;
    }
}

So if I understand it correctly.

A class method does not need you to allocate instance of that object to use / process it. A class method is self contained and can operate without any dependence of the state of any object of that class. A class method is expected to allocate memory for all its own work and deallocate when done, since no instance of that class will be able to free any memory allocated in previous calls to the class method.

A instance method is just the opposite. You cannot call it unless you allocate a instance of that class. Its like a normal class that has a constructor and can have a destructor (that cleans up all the allocated memory).

In most probability (unless you are writing a reusable library, you should not need a class variable.

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

Try Portable UTF-8:

$str = utf8_chr( 0x1000 );
$str = utf8_chr( '\u1000' );
$str = utf8_chr( 4096 );

All work exactly the same way. You can get the codepoint of a character with utf8_ord(). Read more about Portable UTF-8.

You can just give the glyphicon a font-size to your liking:

span.glyphicon-link {
    font-size: 1.2em;
}

In case this helps anyone else, this started happening for me on an older site when "Valid OAuth Redirect URIs" became mandatory. The site was still using the V4 PHP SDK and the problem was resolved for me by upgrading to the V5 SDK.

In Windows 7:

for /f "tokens=1-2 delims=:" %%a in ('ipconfig^|find "IPv4"') do set ip=%%b
set ip=%ip:~1%
echo %ip%
pause

Or you can just use this:

<?
function TestHtml() { 
# PUT HERE YOU PHP CODE
?>
<!-- HTML HERE -->

<? } ?>

to get content from this function , use this :

<?= file_get_contents(TestHtml()); ?>

That's it :)

Another way is to change properties "AutoSize" (set to True) and "AutosizeMode" (set to GrowAndShrink).

This has the effect of the form autosizing to the elements on it and never allowing the user to change its size.

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

Well by doing the above you open yourself to run time errors, unless you are happy to accept that your arraylists can contains both strings and integers and elephants.

Eclipse returns an error because it does not want you to be unaware of the fact that by specifying no type for the generic parameter you are opening yourself up for run time errors. At least with the other two examples you know that you can have objects in your Arraylist and since Inetegers and Strings are both objects Eclipse doesn't warn you.

Either code 2 or 3 are ok. But if you know you will have either only ints or only strings in your arraylist then I would do

ArrayList<Integer> arr = new ArrayList<Integer>();

or

ArrayList<String> arr = new ArrayList<String>();

respectively.

Encountered similar problem: parsing CSV file with special characters like é, è, ö etc ...

The following worked fine for me:

To represent the characters correctly on the html page, the header was needed :

header('Content-Type: text/html; charset=UTF-8');

In order to parse every character correctly, I used:

utf8_encode(fgets($file));

Dont forget to use in all following string operations the 'Multibyte String Functions', like:

mb_strtolower($value, 'UTF-8');

The string can be converted to byte array in few different ways, due to the following fact: .NET supports Unicode, and Unicode standardizes several difference encodings called UTFs. They have different lengths of byte representation but are equivalent in that sense that when a string is encoded, it can be coded back to the string, but if the string is encoded with one UTF and decoded in the assumption of different UTF if can be screwed up.

Also, .NET supports non-Unicode encodings, but they are not valid in general case (will be valid only if a limited sub-set of Unicode code point is used in an actual string, such as ASCII). Internally, .NET supports UTF-16, but for stream representation, UTF-8 is usually used. It is also a standard-de-facto for Internet.

Not surprisingly, serialization of string into an array of byte and deserialization is supported by the class System.Text.Encoding, which is an abstract class; its derived classes support concrete encodings: ASCIIEncoding and four UTFs (System.Text.UnicodeEncoding supports UTF-16)

Ref this link.

For serialization to an array of bytes using System.Text.Encoding.GetBytes. For the inverse operation use System.Text.Encoding.GetChars. This function returns an array of characters, so to get a string, use a string constructor System.String(char[]).
Ref this page.

Example:

string myString = //... some string

System.Text.Encoding encoding = System.Text.Encoding.UTF8; //or some other, but prefer some UTF is Unicode is used
byte[] bytes = encoding.GetBytes(myString);

//next lines are written in response to a follow-up questions:

myString = new string(encoding.GetChars(bytes));
byte[] bytes = encoding.GetBytes(myString);
myString = new string(encoding.GetChars(bytes));
byte[] bytes = encoding.GetBytes(myString);

//how many times shall I repeat it to show there is a round-trip? :-)

In my case I had difficulties with the posted answers. I ended up using the following:

ALTER TABLE table_name CHANGE COLUMN column_name column_name VARCHAR(200) NOT NULL DEFAULT '';

Change VARCHAR(200) to your datatype, and optionally change the default value.

If you don't have a default value you're going to have a problem making this change, as default would be null creating a conflict.

In C

 int a[]={10,20,30,40,50};
 int *p=a;
 printf("%d\n",*p++);//output will be 10
 printf("%d\n",*a++);//will give an error

Pointer p is a "variable", array name a is a "mnemonic" or "synonym", so p++ is valid but a++ is invalid.

a[2] is equals to 2[a] because the internal operation on both of this is "Pointer Arithmetic" internally calculated as *(a+2) equals *(2+a)

You can use:

$ jq 'keys' file.json

$ cat file.json:
{ "Archiver-Version" : "Plexus Archiver", "Build-Id" : "", "Build-Jdk" : "1.7.0_07", "Build-Number" : "", "Build-Tag" : "", "Built-By" : "cporter", "Created-By" : "Apache Maven", "Implementation-Title" : "northstar", "Implementation-Vendor-Id" : "com.test.testPack", "Implementation-Version" : "testBox", "Manifest-Version" : "1.0", "appname" : "testApp", "build-date" : "02-03-2014-13:41", "version" : "testBox" }

$ jq 'keys' file.json
[
  "Archiver-Version",
  "Build-Id",
  "Build-Jdk",
  "Build-Number",
  "Build-Tag",
  "Built-By",
  "Created-By",
  "Implementation-Title",
  "Implementation-Vendor-Id",
  "Implementation-Version",
  "Manifest-Version",
  "appname",
  "build-date",
  "version"
]

UPDATE: To create a BASH array using these keys:

Using BASH 4+:

mapfile -t arr < <(jq -r 'keys[]' ms.json)

On older BASH you can do:

arr=()
while IFS='' read -r line; do
   arr+=("$line")
done < <(jq 'keys[]' ms.json)

Then print it:

printf "%s\n" ${arr[@]}

"Archiver-Version"
"Build-Id"
"Build-Jdk"
"Build-Number"
"Build-Tag"
"Built-By"
"Created-By"
"Implementation-Title"
"Implementation-Vendor-Id"
"Implementation-Version"
"Manifest-Version"
"appname"
"build-date"
"version"

I was having this problem when I started using select2 with XCrud. I solved it by disabling XCrud from loading JQuery, it was it a second time, and loading it below the body tag. So make sure JQuery isn't getting loaded twice on your page.

I worked it around through this "hiding" div ...

<div STYLE="position:absolute;display:none;"><INPUT type='file' id='file1' name='files[]'></div>

a:hover{text-decoration: underline !important}
a{text-decoration: none !important}

Im working with mysql and registered with root user, the solution that work for me is the following:

mysql > SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

If you want to pull down a remote branch to run locally (say for reviewing or testing purposes), and when you $ git pull you get local merge conflicts:

$ git checkout REMOTE-BRANCH
$ git pull  (you get local merge conflicts)
$ git reset --hard HEAD (discards local conflicts, and resets to remote branch HEAD)
$ git pull (now get remote branch updates without local conflicts)

Although the given responses are correct, they modify the initial data frame, which is not always desirable (and, given the OP asked for examples "using apply", it might be they wanted a version that returns a new data frame, as apply does).

This is possible using assign: it is valid to assign to existing columns, as the documentation states (emphasis is mine):

Assign new columns to a DataFrame.

Returns a new object with all original columns in addition to new ones. Existing columns that are re-assigned will be overwritten.

In short:

In [1]: import pandas as pd

In [2]: df = pd.DataFrame([{'a': 15, 'b': 15, 'c': 5}, {'a': 20, 'b': 10, 'c': 7}, {'a': 25, 'b': 30, 'c': 9}])

In [3]: df.assign(a=lambda df: df.a / 2)
Out[3]: 
      a   b  c
0   7.5  15  5
1  10.0  10  7
2  12.5  30  9

In [4]: df
Out[4]: 
    a   b  c
0  15  15  5
1  20  10  7
2  25  30  9

Note that the function will be passed the whole dataframe, not only the column you want to modify, so you will need to make sure you select the right column in your lambda.

Try this

$date = Carbon::parse(date_format($youttimestring,'d/m/Y H:i:s'));
echo $date;

In addition to above : Trailing closure can be used .

downloadFileFromURL(NSURL(string: "url_str")!)  { (success) -> Void in

  // When download completes,control flow goes here.
  if success {
      // download success
  } else {
    // download fail
  }
}

You can't do it the way you wanted.

Use ArrayList instead:

List<String> a = new ArrayList<String>();
a.add("kk");
a.add("pp");

And then you can have an array again by using toArray:

String[] myArray = new String[a.size()];
a.toArray(myArray);

For Intellij 2018 it's quite confusing as there's an Editor ? Font section but it's usually overriden by Editor ? Color Scheme ? Color Scheme Font:

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

(Reference: Chart.js)

N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion

I got this resolved in angular with (click) = "someFuncionName()" in the .html file for the specific component.

Another possible solution with JS

function onSelect(e) {
    if (e.files.length > 5) {
        alert("Only 5 files accepted.");
        e.preventDefault();
    }
}

This is for windows:

For example, I have a folder named "mygrapher" on my desktop. Inside, there's folders called "calculation" and "graphing" that contain Python files that my main file "grapherMain.py" needs. Also, "grapherMain.py" is stored in "graphing". To run everything without moving files, I can make a batch script. Let's call this batch file "rungraph.bat".

@ECHO OFF
setlocal
set PYTHONPATH=%cd%\grapher;%cd%\calculation
python %cd%\grapher\grapherMain.py
endlocal

This script is located in "mygrapher". To run things, I would get into my command prompt, then do:

>cd Desktop\mygrapher (this navigates into the "mygrapher" folder)
>rungraph.bat (this executes the batch file)

I fixed it by overriding the hasError method from DefaultResponseErrorHandler class:

public class BadRequestSafeRestTemplateErrorHandler extends DefaultResponseErrorHandler
{
    @Override
    protected boolean hasError(HttpStatus statusCode)
    {
        if(statusCode == HttpStatus.BAD_REQUEST)
        {
            return false;
        }
        return statusCode.isError();
    }
}

And you need to set this handler for restemplate bean:

@Bean
    protected RestTemplate restTemplate(RestTemplateBuilder builder)
    {
        return builder.errorHandler(new BadRequestSafeRestTemplateErrorHandler()).build();
    }

i use firebase-database in html signup but last error i cannot understand if anybody know tell me . error is "Failed to load resource: the server responded with a status of 404 ()"

Not sure if JSF provides a built-in functionality, but you could use java.sql.Date's constructor to convert to a date object: http://download.oracle.com/javase/1.5.0/docs/api/java/sql/Date.html#Date(long)

Then you should be able to use higher level features provided by Java SE, Java EE to display and format the extracted date. You could instantiate a java.util.Calendar and explicitly set the time: http://download.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#setTime(java.util.Date)

EDIT: The JSF components should not take care of the conversion. Your data access layer (persistence layer) should take care of this. In other words, your JSF components should not handle the long typed attributes but only a Date or Calendar typed attributes.

I'm not sure exactly what you mean by "full Git Bash environment", but I get the nice prompt if I do

"C:\Program Files\Git\bin\sh.exe" --login

In PowerShell

& 'C:\Program Files\Git\bin\sh.exe' --login

The --login switch makes the shell execute the login shell startup files.

OK. We have official document now. It talked all I have mentioned, in a better way.

Read more detailed here.

Yes, the main difference is surfaceView can be updated on the background thread. However, there are more you might care.

• surfaceView has dedicate surface buffer while all the view shares one surface buffer that is allocated by ViewRoot. In another word, surfaceView cost more resources.

• surfaceView cannot be hardware accelerated (as of JB4.2) while 95% operations on normal View are HW accelerated using openGL ES.

• More work should be done to create your customized surfaceView. You need to listener to the surfaceCreated/Destroy Event, create an render thread, more importantly, synchronized the render thread and main thread. However, to customize the View, all you need to do is override onDraw method.

• The timing to update is different. Normal view update mechanism is constraint or controlled by the framework:You call view.invalidate in the UI thread or view.postInvalid in other thread to indicate to the framework that the view should be updated. However, the view won't be updated immediately but wait until next VSYNC event arrived. The easy approach to understand VSYNC is to consider it is as a timer that fire up every 16ms for a 60fps screen. In Android, all the normal view update (and display actually but I won't talk it today), is synchronized with VSYNC to achieve better smoothness. Now,back to the surfaceView, you can render it anytime as you wish. However, I can hardly tell if it is an advantage, since the display is also synchronized with VSYNC, as stated previously.

With the help of jquery it can be done as follows.

$("#color").prop('disabled', true);

Runnable is just an interface, which provides the method run. Threads are implementations and use Runnable to call the method run().

I had similar problem I found the issue I was mixing the annotations some of them above the attributes and some of them above public methods. I just put all of them above attributes and it works.

It`s a so easy solution:

To Add

Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
key.SetValue("Your Application Name", Application.ExecutablePath);

To Remove

Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
key.DeleteValue("Your Application Name", false);

One more solution:

#footer { display:table; margin:0 auto; }
#footer li { display:table-cell; padding: 0px 10px; }

Then ul doesn't jump to the next line in case of zooming text.

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

What I do when it happens is Disable the COM port into the Device Manager and Enable it again.

It stop the communications with another program or thread and become free for you.

I hope this works for you. Regards.

Using SVN 1.8, deleting lock file does not help (lock file does not exists).

Refresh/Cleanup did not solve either.

What did solve:

1) Backup your directory, just incase...
2) Team... Disconnect. Choose to remove .svn files
3) Add it again to SVN.

Note: In my case, error was due to loss of network connection during initial commit.

In bash, I used this libreoffice command to convert all my xlsx files in the current directory:

for i   in *.xlsx; do  libreoffice --headless --convert-to csv "$i" ; done

It takes care of spaces in the filename.

Tried again some years later, and it didn't work. This thread gives some tips, but the quickiest solution was to run as root (or running a sudo libreoffice). Not elegant, but quick.

Use the command scalc.exe in Windows

Try this:

TypeScript file code:

(<HTMLInputElement>document.getElementById("name")).value

HTML code:

 <input id="name" type="text" #name /> 

I think Manoj Gupta had the best answer from what I'm seeing. However, the remove command doesn't get rid of any configuration folders or files that may be leftover. Use:

sudo apt-get purge --auto-remove nodejs

The purge command should remove the package and then clean up any configuration files. (see this question for more info on the difference between purge and remove). The auto-remove flag will do the same for packages that were installed by NodeJS.

See the accepted answer on this question for a better explanation.

Although don't forget to handle NPM! Josh's answer covers that.

  import ReactDOM from 'react-dom';
  //...
  componentDidMount() {
    var n = ReactDOM.findDOMNode(this);
    console.log(n.offsetTop);
  }

You can just grab the offsetTop from the Node.

If you want to remove the namespace you may also want to remove the version, to save you searching I've added that functionality so the below code will do both.

I've also wrapped it in a generic method as I'm creating very large xml files which are too large to serialize in memory so I've broken my output file down and serialize it in smaller "chunks":

    public static string XmlSerialize<T>(T entity) where T : class
    {
        // removes version
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.OmitXmlDeclaration = true;

        XmlSerializer xsSubmit = new XmlSerializer(typeof(T));
        using (StringWriter sw = new StringWriter())
        using (XmlWriter writer = XmlWriter.Create(sw, settings))
        {
            // removes namespace
            var xmlns = new XmlSerializerNamespaces();
            xmlns.Add(string.Empty, string.Empty);

            xsSubmit.Serialize(writer, entity, xmlns);
            return sw.ToString(); // Your XML
        }
    }

From your comments,

the tax amount rounded to the 4th decimal and the total price rounded to the 2nd decimal.

Using the example in the comments, I might foresee a case where you have 400 sales of $1.47. Sales-before-tax would be $588.00, and sales-after-tax would sum to $636.51 (accounting for $48.51 in taxes). However, the sales tax of $0.121275 * 400 would be $48.52.

This was one way, albeit contrived, to force a penny's difference.

I would note that there are payroll tax forms from the IRS where they do not care if an error is below a certain amount (if memory serves, $0.50).

Your big question is: does anybody care if certain reports are off by a penny? If the your specs say: yes, be accurate to the penny, then you should go through the effort to convert to DECIMAL.

I have worked at a bank where a one-penny error was reported as a software defect. I tried (in vain) to cite the software specifications, which did not require this degree of precision for this application. (It was performing many chained multiplications.) I also pointed to the user acceptance test. (The software was verified and accepted.)

Alas, sometimes you just have to make the conversion. But I would encourage you to A) make sure that it's important to someone and then B) write tests to show that your reports are accurate to the degree specified.

One way:

We have Month API in Java (java.time.Month). We can get by using Month.of(month);

Here, the Month are indexed as numbers so either you can provide by Month.JANUARY or provide an index in the above API such as 1, 2, 3, 4.

Second way:

ZonedDateTime.now().getMonth();

This is available in java.time.ZonedDateTime.

Here's an inline version if you don't want to create a whole new type:

export interface ISomeInterface extends Array<{
    [someindex: string]: number;
}> { };

One problem is that a ternary relational construct would introduce serious parser problems:

<expr> ::= <expr> <rel-op> <expr> |
           ... |
           <expr> <rel-op> <expr> <rel-op> <expr>

When you try to express a grammar with those productions using a typical PGS, you'll find that there is a shift-reduce conflict at the point of the first <rel-op>. The parse needs to lookahead an arbitrary number of symbols to see if there is a second <rel-op> before it can decide whether the binary or ternary form has been used. In this case, you could not simply ignore the conflict because that would result in incorrect parses.

I'm not saying that this grammar is fatally ambiguous. But I think you'd need a backtracking parser to deal with it correctly. And that is a serious problem for a programming language where fast compilation is a major selling point.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

I would like to add recommendations from oracle trouble shooting article.

Exception in thread thread_name: java.lang.OutOfMemoryError: Java heap space

The detail message Java heap space indicates object could not be allocated in the Java heap. This error does not necessarily imply a memory leak

Possible causes:

1. Simple configuration issue, where the specified heap size is insufficient for the application.

2. Application is unintentionally holding references to objects, and this prevents the objects from being garbage collected.

3. Excessive use of finalizers.

One other potential source of this error arises with applications that make excessive use of finalizers. If a class has a finalize method, then objects of that type do not have their space reclaimed at garbage collection time

After garbage collection, the objects are queued for finalization, which occurs at a later time. finalizers are executed by a daemon thread that services the finalization queue. If the finalizer thread cannot keep up with the finalization queue, then the Java heap could fill up and this type of OutOfMemoryError exception would be thrown.

One scenario that can cause this situation is when an application creates high-priority threads that cause the finalization queue to increase at a rate that is faster than the rate at which the finalizer thread is servicing that queue.

Your script contains errors as well, for example if you have dos2unix installed your install works but if you don't like I did then it will fail with dependency issues.

I found this by accident as I was making a script file of this to give to my friend who is new to Linux and because I made the scripts on windows I directed him to install it, at the time I did not have dos2unix installed thus I got errors.

here is a copy of the script I made for your solution but have dos2unix installed.

#!/bin/sh
echo "deb http://ftp.debian.org/debian sid main" >> /etc/apt/sources.list
apt-get update
apt-get -t sid install libc6 libc6-dev libc6-dbg
echo "Please remember to hash out sid main from your sources list. /etc/apt/sources.list"

this script has been tested on 3 machines with no errors.

Queue is JMS managed object used for holding messages waiting for subscribers to consume. When all subscribers consumed the message , message will be removed from queue.

Topic is that all subscribers to a topic receive the same message when the message is published.

Did you sign with the debug key by mistake?

Google Play does not allow you to publish an app signed with your debug keystore. If you try to upload such an APK, Google Play will fail with the message "You uploaded an APK that was signed in debug mode. You need to sign your APK in release mode."

However, if you try to upload an update which is signed with the debug keystore, you will not see this message; Google Play will display the message shown in the question, referring to SHA1 fingerprints.

So firstly, check whether you signed the app with your debug key by mistake.

How do I check which signing keys were used?

Gather the information from the APK

You can check which certificates the original APK and update APK were signed with by using these commands, using the Java keytool:

keytool -list -printcert -jarfile original.apk
keytool -list -printcert -jarfile update.apk

This shows you detailed information about the how an APK was signed, for example:

Owner: CN=My App, O=My Company, L=Somewhere, C=DE
Issuer: CN=My App, O=My Company, L=Somewhere, C=DE
Serial number: 4790b086
Valid from: Mon Nov 11 15:01:28 GMT 2013 until: Fri Mar 29 16:01:28 BST 2041
Certificate fingerprints:
  MD5:  A3:2E:67:AF:74:3A:BD:DD:A2:A9:0D:CA:6C:D4:AF:20
  SHA1: A6:E7:CE:64:17:45:0F:B4:C7:FC:76:43:90:04:DC:A7:84:EF:33:E9
  SHA256: FB:6C:59:9E:B4:58:E3:62:AD:81:42:...:09:FC:BC:FE:E7:40:53:C3:D8:14:4F
         Signature algorithm name: SHA256withRSA
         Version: 3

The important parts to note here — for each APK — are the SHA1 fingerprint value, the Owner identity value, and the Valid from/until dates.

If that keytool command doesn't work (the -jarfile option requires Java 7), you can get more basic information via the jarsigner command:

jarsigner -verify -verbose:summary -certs original.apk
jarsigner -verify -verbose:summary -certs update.apk

This unfortunately does not show the SHA1 fingerprint, but does show the X.509 owner identity, along with the certificate expiry dates. For example:

sm  4642892 Thu Apr 17 10:57:44 CEST 2014 classes.dex (and 412 more)

    X.509, CN=My App, O=My Company, L=Somewhere, C=DE
    [certificate is valid from 11/11/13 12:12 to 29/03/41 12:12]
    [CertPath not validated: Path does not chain with any of the trust anchors]

You can ignore any "CertPath not validated" message, along with warnings about certificate chains or timestamps; they're not relevant in this case.

Compare the Owner, SHA1 and Expiry values between the APKs

• If the Owner/X.509 identity value is CN=Android Debug, O=Android, C=US, then you have signed the APK with your debug key, not the original release key

• If the SHA1 fingerprint value is different between the original and update APKs, then you did not use the same signing key for both APKs

• If the Owner/X.509 identity values are different, or the certificate expiry dates differ between the two APKs, then you did not use the same signing key for both APKs

Note that even if the Owner/X.509 values are identical between the two certificates, this doesn't mean that the certificates are identical — if anything else does not match — such as the fingerprint values — then the certificates are different.

Search for the original keystore, check backups

If the two APKs have different certificate information, then you must find the original keystore, i.e. the file with the first SHA1 fingerprint value that Google Play (or keytool) told you.

Search through all the keystore files you can find on your computer, and in any backups you have, until you have the one with the correct SHA1 fingerprint:

keytool -list -keystore my-release.keystore

Just press Enter if prompted for the password — you don't necessarily have to enter it if you just want to quickly check the SHA1 value.

I can't find the original keystore anywhere

If you cannot find the original keystore, you will never be able to publish any updates to this particular app.

Android mentions this explicitly on the Signing Your Application page:

Warning: Keep your keystore and private key in a safe and secure place, and ensure that you have secure backups of them. If you publish an app to Google Play and then lose the key with which you signed your app, you will not be able to publish any updates to your app, since you must always sign all versions of your app with the same key.

After the first release of an APK, all subsequent releases must be signed with the exact same key.

Can I extract the original signing key from the original APK?

No. This is not possible. The APK only contains public information, and not your private key information.

Can I migrate to a new signing key?

No. Even if you do find the original, you can't sign an APK with key A, then sign the next update with both keys A and B, then sign the next update after that with only key B.

Signing an APK (or any JAR file) with multiple keys is technically possible, but Google Play no longer accepts APKs with multiple signatures.

Attempting to do so will result in the message "Your APK has been signed with multiple certificates. Please only sign it with one certificate and upload it again."

What can I do?

You will have to build your app with a new application ID (e.g. change from "com.example.myapp" to "com.example.myapp2") and create a brand new listing on Google Play.

Possibly you will also have to change your code so that people can install the new app even if they have the old app installed, e.g. you need to make sure that you don't have conflicting content providers.

You will lose your existing install base, reviews etc., and will have to find a way to get your existing customers to uninstall the old app and install the new version.

Again, ensure you have secure backups of the keystore and password(s) you use for this version.

UPDATE 2018: C++20 will come with templated and conceptualized lambdas. The feature has already been integrated into the standard draft.

UPDATE 2014: C++14 has been released this year and now provides Polymorphic lambdas with the same syntax as in this example. Some major compilers already implement it.

At it stands (in C++11), sadly no. Polymorphic lambdas would be excellent in terms of flexibility and power.

The original reason they ended up being monomorphic was because of concepts. Concepts made this code situation difficult:

template <Constraint T>
void foo(T x)
{
    auto bar = [](auto x){}; // imaginary syntax
}

In a constrained template you can only call other constrained templates. (Otherwise the constraints couldn't be checked.) Can foo invoke bar(x)? What constraints does the lambda have (the parameter for it is just a template, after all)?

Concepts weren't ready to tackle this sort of thing; it'd require more stuff like late_check (where the concept wasn't checked until invoked) and stuff. Simpler was just to drop it all and stick to monomorphic lambdas.

However, with the removal of concepts from C++0x, polymorphic lambdas become a simple proposition again. However, I can't find any proposals for it. :(

Use command substitution instead of quotes to execute find instead of passing the command as a string:

for line in $(find . -iname '*.txt'); do 
     echo $line
     ls -l $line; 
done

Table::where('id', 1)->get(['name','surname']);

i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.

Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.

.url files can be made by saving a favourite with internet exploiter.

Why don't you try to grep the return of your command ? Something like :

adb devices -l | grep 123abc12

It should return only the line you want to.

Yes. You can pass a java array to Arrays.asList(Object[]).

List<String> fixedSizeList = Arrays.asList(new String[100]);

You cannot insert new Strings to the fixedSizeList (it already has 100 elements). You can only set its values like this:

fixedSizeList.set(7, "new value");

That way you have a fixed size list. The thing functions like an array and I can't think of a good reason to use it. I'd love to hear why you want your fixed size collection to be a list instead of just using an array.

HTTP_CLIENT_IP is the most reliable way of getting the user's IP address. Next is HTTP_X_FORWARDED_FOR, followed by REMOTE_ADDR. Check all three, in that order, assuming that the first one that is set (isset($_SERVER['HTTP_CLIENT_IP']) returns true if that variable is set) is correct. You can independently check if the user is using a proxy using various methods. Check this out.

To set thousand separator, say 123,456.78 you have to use DecimalFormat:

     DecimalFormat df = new DecimalFormat("#,###.00");
     System.out.println(df.format(new BigDecimal(123456.75)));
     System.out.println(df.format(new BigDecimal(123456.00)));
     System.out.println(df.format(new BigDecimal(123456123456.78)));

Here is the result:

123,456.75
123,456.00
123,456,123,456.78

Although I set #,###.00 mask, it successfully formats the longer values too. Note that the comma(,) separator in result depends on your locale. It may be just space( ) for Russian locale.

You should use Impersonation to elevate the state.

WindowsIdentity identity = new WindowsIdentity(accessToken);
WindowsImpersonationContext context = identity.Impersonate();

Don't forget to undo the impersonated context when you are done.

If you don't want an array then how about an object?

var months = {
    'Jan' : '01',
    'Feb' : '02',
    'Mar' : '03',
    'Apr' : '04',
    'May' : '05',
    'Jun' : '06',
    'Jul' : '07',
    'Aug' : '08',
    'Sep' : '09',
    'Oct' : '10',
    'Nov' : '11',
    'Dec' : '12'
}

You can also pass arguments to getters by returning a function. This is particularly useful when you want to query an array in the store:

getters: {
  // ...
  getTodoById: (state) => (id) => {
    return state.todos.find(todo => todo.id === id)
  }
}
store.getters.getTodoById(2) // -> { id: 2, text: '...', done: false }

Note that getters accessed via methods will run each time you call them, and the result is not cached.

That is called Method-Style Access and it is documented on the Vue.js docs.

Get your response via a regular http-request, using:

• Apache HttpComponents
• the built-in URLConnection con = new URL("http://example.com").openConnection();

The next step is parsing it. Take a look at this article for a choice of parser.

If for matching identical images ( same size/orientation )

// Compare two images by getting the L2 error (square-root of sum of squared error).
double getSimilarity( const Mat A, const Mat B ) {
if ( A.rows > 0 && A.rows == B.rows && A.cols > 0 && A.cols == B.cols ) {
    // Calculate the L2 relative error between images.
    double errorL2 = norm( A, B, CV_L2 );
    // Convert to a reasonable scale, since L2 error is summed across all pixels of the image.
    double similarity = errorL2 / (double)( A.rows * A.cols );
    return similarity;
}
else {
    //Images have a different size
    return 100000000.0;  // Return a bad value
}

To add to the previous explanations, static method calls are bound to a specific method at compile-time, which rather rules out polymorphic behavior.

i have tested that and it worked

val x = 9
def printType[T](x:T) :Unit = {println(x.getClass.toString())}

You can use the following code to get last day of the month

public static String getLastDayOfTheMonth(String date) {
        String lastDayOfTheMonth = "";

        SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
        try{
        java.util.Date dt= formatter.parse(date);
        Calendar calendar = Calendar.getInstance();  
        calendar.setTime(dt);  

        calendar.add(Calendar.MONTH, 1);  
        calendar.set(Calendar.DAY_OF_MONTH, 1);  
        calendar.add(Calendar.DATE, -1);  

        java.util.Date lastDay = calendar.getTime();  

        lastDayOfTheMonth = formatter.format(lastDay);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return lastDayOfTheMonth;
    }

This is similar to some of the other answers, but is compact and avoids the conversion to dictionary if you already have a list.

Given a ComboBox "combobox" on a windows form and a class SomeClass with the string type property Name,

List<SomeClass> list = new List<SomeClass>();

combobox.DisplayMember = "Name";
combobox.DataSource = list;

Which means that combobox.SelectedItem is a SomeClass object from list, and each item in combobox will be displayed using its property Name.

You can read the selected item using

SomeClass someClass = (SomeClass)combobox.SelectedItem;

cd my_directory && tar -czvf ../my_directory.tar.gz $(ls -A) && cd ..

This one worked for me and it's include all hidden files without putting all files in a root directory named "." like in tomoe's answer :

Have a look at the Android developers page: http://developer.android.com/training/basics/fragments/communicating.html#DefineInterface

Basically, you define an interface in your Fragment A, and let your Activity implement that Interface. Now you can call the interface method in your Fragment, and your Activity will receive the event. Now in your activity, you can call your second Fragment to update the textview with the received value

Your Activity implements your interface (See FragmentA below)

public class YourActivity implements FragmentA.TextClicked{
    @Override
    public void sendText(String text){
        // Get Fragment B
        FraB frag = (FragB)
            getSupportFragmentManager().findFragmentById(R.id.fragment_b);
        frag.updateText(text);
    }
}

Fragment A defines an Interface, and calls the method when needed

public class FragA extends Fragment{

    TextClicked mCallback;

    public interface TextClicked{
        public void sendText(String text);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        // This makes sure that the container activity has implemented
        // the callback interface. If not, it throws an exception
        try {
            mCallback = (TextClicked) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                + " must implement TextClicked");
        }
    }

    public void someMethod(){
        mCallback.sendText("YOUR TEXT");
    }

    @Override
    public void onDetach() {
        mCallback = null; // => avoid leaking, thanks @Deepscorn
        super.onDetach();
    }
}

Fragment B has a public method to do something with the text

public class FragB extends Fragment{

    public void updateText(String text){
        // Here you have it
    }
}

List

1. Is an Ordered grouping of elements.
2. List is used to collection of elements with duplicates.
3. New methods are defined inside List interface.

Set

1. Is an Unordered grouping of elements.
2. Set is used to collection of elements without duplicates.
3. No new methods are defined inside Set interface, so we have to use Collection interface methods only with Set subclasses.

Only update your import.

import android.app.AlertDialog;

to

import android.support.v7.app.AlertDialog;

It will be fixed.

Shouldn't it be just the .list-group? See below,

<ul class="list-group">
  <li class="list-group-item active">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Reference: Bootstrap 4 Basic Example of a List group

Personally, I would shorten it a touch too if all you need is the columns:

For i = LBound(arr1) To UBound(arr1)
    Sheets("SheetA").Columns(arr1(i)).Copy
    Sheets("SheetB").Columns(arr2(i)).PasteSpecial xlPasteValues
    Application.CutCopyMode = False
Next

as from this code snippet, there isnt much point in lastrow or firstrowDB

Another solution to the problem could be the following set of CSS rules:

.ellipsis{
 white-space:nowrap;
 overflow:hidden;
}

.ellipsis:after{
  content:'...';
}

The only drawback with the above CSS is that it would add the "..." irrespective of whether the text-overflows the container or not. Still, if you have a case where you have a bunch of elements and are sure that content will overflow, this one would be a simpler set of rules.

My two cents. Hats off to the original technique by Justin Maxwell

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

HashSet don't maintain the order of insertion item
LinkedHashSet maintain the order of insertion item

Example

Set<String> set = ...;// using new HashSet<>() OR new LinkedHashSet<>()
set.add("2");
set.add("1");
set.add("ab");
for(String value : set){
   System.out.println(value);
}  

HashSet output

1
ab
2

LinkedHashSet output

2
1
ab

Write this code in your on backpressed override method

@Override
public void onBackPressed() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
}

You can accomplish it with INSERT as below:

INSERT INTO mytable (id, a, b, c)
VALUES (1, 'a1', 'b1', 'c1'),

ON DUPLICATE KEY UPDATE id=VALUES(id),
a=VALUES(a),
b=VALUES(b),

This insert new values into table, but if primary key is duplicated (already inserted into table) that values you specify would be updated and same record would not be inserted second time.

Thank you for all answers! I found it! It calls "Column selection (for Sublime)" and "Column Mode Editing (for Notepad++)" https://www.sublimetext.com/docs/3/column_selection.html

If your keys are dynamic I would suggest deserializing directly into a DataTable:

    class SampleData
    {
        [JsonProperty(PropertyName = "items")]
        public System.Data.DataTable Items { get; set; }
    }

    public void DerializeTable()
    {
        const string json = @"{items:["
            + @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
            + @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
            + @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
        var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
        var table = sampleData.Items;

        // write tab delimited table without knowing column names
        var line = string.Empty;
        foreach (DataColumn column in table.Columns)            
            line += column.ColumnName + "\t";                       
        Console.WriteLine(line);

        foreach (DataRow row in table.Rows)
        {
            line = string.Empty;
            foreach (DataColumn column in table.Columns)                
                line += row[column] + "\t";                                   
            Console.WriteLine(line);
        }

        // Name   Age   Job    
        // AAA    22    PPP    
        // BBB    25    QQQ    
        // CCC    38    RRR    
    }

You can determine the DataTable column names and types dynamically once deserialized.

This fixed it for me: Open maven projects tab on the right. Add the pom if not yet present, then click refresh on the top left of the tab.

When you run the Windows Command Prompt, and type in python, it starts the Python interpreter.

Typing it again tries to interpret python as a variable, which doesn't exist and thus won't work:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line

C:\Users\USER>

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python is interpreted as a variable, which you have not defined.

Here is a slight improvement on the accepted answer that avoids having to use sapply(). Also forces non-first characters to lower.

titleCase <- Vectorize(function(x) {
  
  # Split input vector value
  s <- strsplit(x, " ")[[1]]
  
  # Perform title casing and recombine
  ret <- paste(toupper(substring(s, 1,1)), tolower(substring(s, 2)),
        sep="", collapse=" ")
  
  return(ret)
  
}, USE.NAMES = FALSE)


name <- c("zip CODE", "statE", "final couNt")

titleCase(name)

#> "Zip Code"       "State" "Final Count" 

Set oShell = WScript.CreateObject("WSCript.shell")
oShell.run "cmd cd /d C:dir_test\file_test & sanity_check_env.bat arg1"

You can try like following:

string output = JsonConvert.SerializeObject(jsonStr);

Or just...

var response = (function() {
    var a;
    // calculate a
    return a;
})();  

In this case, the response variable receives the return value of the function. The function executes immediately.

You can use this construct if you want to populate a variable with a value that needs to be calculated. Note that all calculation happens inside the anonymous function, so you don't pollute the global namespace.

Try Collections.shuffle(list).If usage of this method is barred for solving the problem, then one can look at the actual implementation.

The reason of why your code throws an UnboundLocalError is already well explained in other answers.

But it seems to me that you're trying to build something that works like itertools.count().

So why don't you try it out, and see if it suits your case:

>>> from itertools import count
>>> counter = count(0)
>>> counter
count(0)
>>> next(counter)
0
>>> counter
count(1)
>>> next(counter)
1
>>> counter
count(2)

For those that come here using MariaDB:

Note that MariaDB allows DROP CONSTRAINT statements in general, for example for dropping check constraints:

ALTER TABLE table_name
DROP CONSTRAINT constraint_name;

Issue happens because Microsoft Security Update MS11-100 limits number of keys in Forms collection during HTTP POST request. To alleviate this problem you need to increase that number.

This can be done in your application Web.Config in the <appSettings> section (create the section directly under <configuration> if it doesn’t exist). Add 2 lines similar to the lines below to the section:

<add key="aspnet:MaxHttpCollectionKeys" value="2000" />
<add key="aspnet:MaxJsonDeserializerMembers" value="2000" />

The above example set the limit to 2000 keys. This will lift the limitation and the error should go away.

If one wants to support Generics (in an extension method) this is the pattern...

public  static List<T> Deserialize<T>(this string SerializedJSONString)
{
    var stuff = JsonConvert.DeserializeObject<List<T>>(SerializedJSONString);
    return stuff;
}

It is used like this:

var rc = new MyHttpClient(URL);
//This response is the JSON Array (see posts above)
var response = rc.SendRequest();
var data = response.Deserialize<MyClassType>();

MyClassType looks like this (must match name value pairs of JSON array)

[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
 public class MyClassType
 {
    [JsonProperty(PropertyName = "Id")]
    public string Id { get; set; }

    [JsonProperty(PropertyName = "Name")]
    public string Name { get; set; }

    [JsonProperty(PropertyName = "Description")]
    public string Description { get; set; }

    [JsonProperty(PropertyName = "Manager")]
    public string Manager { get; set; }

    [JsonProperty(PropertyName = "LastUpdate")]
    public DateTime LastUpdate { get; set; }
 }

Ryan Cook's answer is close to what I'm after and may be more appropriate for other developers. However, it adds http:// to the beginning of the string and in general it does a bit more formatting than I'm after.

Also, for my use cases, resolving relative paths is not important.

mdsharp's answer also contains the seed of a good idea, although that actual implementation needed a few more details to be complete. This is an attempt to flesh it out (and I'm using this in production):

C#

public string UrlCombine(string url1, string url2)
{
    if (url1.Length == 0) {
        return url2;
    }

    if (url2.Length == 0) {
        return url1;
    }

    url1 = url1.TrimEnd('/', '\\');
    url2 = url2.TrimStart('/', '\\');

    return string.Format("{0}/{1}", url1, url2);
}

VB.NET

Public Function UrlCombine(ByVal url1 As String, ByVal url2 As String) As String
    If url1.Length = 0 Then
        Return url2
    End If

    If url2.Length = 0 Then
        Return url1
    End If

    url1 = url1.TrimEnd("/"c, "\"c)
    url2 = url2.TrimStart("/"c, "\"c)

    Return String.Format("{0}/{1}", url1, url2)
End Function

This code passes the following test, which happens to be in VB:

<TestMethod()> Public Sub UrlCombineTest()
    Dim target As StringHelpers = New StringHelpers()

    Assert.IsTrue(target.UrlCombine("test1", "test2") = "test1/test2")
    Assert.IsTrue(target.UrlCombine("test1/", "test2") = "test1/test2")
    Assert.IsTrue(target.UrlCombine("test1", "/test2") = "test1/test2")
    Assert.IsTrue(target.UrlCombine("test1/", "/test2") = "test1/test2")
    Assert.IsTrue(target.UrlCombine("/test1/", "/test2/") = "/test1/test2/")
    Assert.IsTrue(target.UrlCombine("", "/test2/") = "/test2/")
    Assert.IsTrue(target.UrlCombine("/test1/", "") = "/test1/")
End Sub

You can also use the join command (dplyr).

For example:

new_dataset <- dataset1 %>% right_join(dataset2, by=c("column1","column2"))

Try this Code

<select name="forma" onchange="location = this.options[this.selectedIndex].value;">
 <option value="Home.php">Home</option>
 <option value="Contact.php">Contact</option>
 <option value="Sitemap.php">Sitemap</option>
</select>

All C++ compilers have one serious performance problem to deal with. Compiling C++ code is a long, slow process.

Compiling headers included on top of C++ files is a very long, slow process. Compiling the huge header structures that form part of Windows API and other large API libraries is a very, very long, slow process. To have to do it over, and over, and over for every single Cpp source file is a death knell.

This is not unique to Windows but an old problem faced by all compilers that have to compile against a large API like Windows.

The Microsoft compiler can ameliorate this problem with a simple trick called precompiled headers. The trick is pretty slick: although every CPP file can potentially and legally give a sligthly different meaning to the chain of header files included on top of each Cpp file (by things like having different macros #define'd in advance of the includes, or by including the headers in different order), that is most often not the case. Most of the time, we have dozens or hundreds of included files, but they all are intended to have the same meaning for all the Cpp files being compiled in your application.

The compiler can make huge time savings if it doesn't have to start to compile every Cpp file plus its dozens of includes literally from scratch every time.

The trick consists of designating a special header file as the starting point of all compilation chains, the so called 'precompiled header' file, which is commonly a file named stdafx.h simply for historical reasons.

Simply list all your big huge headers for your APIs in your stdafx.h file, in the appropriate order, and then start each of your CPP files at the very top with an #include "stdafx.h", before any meaningful content (just about the only thing allowed before is comments).

Under those conditions, instead of starting from scratch, the compiler starts compiling from the already saved results of compiling everything in stdafx.h.

I don't believe that this trick is unique to Microsoft compilers, nor do I think it was an original development.

For Microsoft compilers, the setting that controls the use of precompiled headers is controlled by a command line argument to the compiler: /Yu "stdafx.h". As you can imagine, the use of the stdafx.h file name is simply a convention; you can change the name if you so wish.

In Visual Studio 2010, this setting is controlled from the GUI via Right-clicking on a CPP Project, selecting 'Properties' and navigating to "Configuration Properties\C/C++\Precompiled Headers". For other versions of Visual Studio, the location in the GUI will be different.

Note that if you disable precompiled headers (or run your project through a tool that doesn't support them), it doesn't make your program illegal; it simply means that your tool will compile everything from scratch every time.

If you are creating a library with no Windows dependencies, you can easily comment out or remove #includes from the stdafx.h file. There is no need to remove the file per se, but clearly you may do so as well, by disabling the precompile header setting above.

You would be best off using collections.defaultdict (added in Python 2.5). This allows you to specify the default object type of a missing key (such as a list).

So instead of creating a key if it doesn't exist first and then appending to the value of the key, you cut out the middle-man and just directly append to non-existing keys to get the desired result.

A quick example using your data:

>>> from collections import defaultdict
>>> data = [(2010, 2), (2009, 4), (1989, 8), (2009, 7)]
>>> d = defaultdict(list)
>>> d
defaultdict(<type 'list'>, {})
>>> for year, month in data:
...     d[year].append(month)
... 
>>> d
defaultdict(<type 'list'>, {2009: [4, 7], 2010: [2], 1989: [8]})

This way you don't have to worry about whether you've seen a digit associated with a year or not. You just append and forget, knowing that a missing key will always be a list. If a key already exists, then it will just be appended to.

Stack Implementation in Java

  class stack
  {  private int top;
     private int[] element;
      stack()
      {element=new int[10];
      top=-1;
      }
      void push(int item)
      {top++;
      if(top==9)
          System.out.println("Overflow");
      else
              {
               top++;
      element[top]=item;

      }

      void pop()
      {if(top==-1)
          System.out.println("Underflow");
      else  
      top--;
      }
      void display()
      {
          System.out.println("\nTop="+top+"\nElement="+element[top]);
      }

      public static void main(String args[])
      {
        stack s1=new stack();
        s1.push(10);
        s1.display();
        s1.push(20);
        s1.display();
        s1.push(30);
        s1.display();
        s1.pop();
        s1.display();
      }

  }

Output

Top=0
Element=10
Top=1
Element=20
Top=2
Element=30
Top=1
Element=20

strtok maintains a static, internal reference pointing to the next available token in the string; if you pass it a NULL pointer, it will work from that internal reference.

This is the reason strtok isn't re-entrant; as soon as you pass it a new pointer, that old internal reference gets clobbered.

Laravel 5.5 comes with mix , the replacement for Elixir, the external css(sass) can be extracted to resources/assets/css(sass) and import to app.css(scss) or give the correct path to your node_module folder that contains the library and can be used as

<link rel="stylesheet" href="{{ mix('css/app.css') }}" >

The same can be done for Javascript too .

Since you are using Access to compose the query, you have to stick to Access's version of SQL.

To choose between several different return values, use the switch() function. So to translate and extend your example a bit:

select switch(
  age > 40, 4,
  age > 25, 3,
  age > 20, 2,
  age > 10, 1,
  true, 0
) from demo

The 'true' case is the default one. If you don't have it and none of the other cases match, the function will return null.

The Office website has documentation on this but their example syntax is VBA and it's also wrong. I've given them feedback on this but you should be fine following the above example.

For that, you need to update the redis configuration file.By default, there is no any password for redis.

01) open redis configuration file

sudo vi /etc/redis/redis.conf

find requirepass field under SECURITY section and uncomment that field.Then set your password instead of "foobared"

# requirepass foobared

It should be like,

requirepass YOUR_PASSWORD

Then restart redis and start redis-cli.

If you need to check whether you have set the password correctly, you can run below commads in redis-cli.

I fixed it very simple:

.parent {
  position: relative;
  z-index: 1;
}

.child {
  position: absolute;
  z-index: -1;
}

What this does is stack the parent at z-index: 1, which gives the child room to 'end up' at z-index: 0 since other dom elements 'exist' on z-index: 0. If we don't give the parent an z-index of 1 the child will end up below the other dom elements and thus will not be visible.

This also works for pseudo elements like :after

$('[name="ElementNameHere"]').doStuff();

for android studio 3.1

If you want your default android studio change, just follow bellow steps:

first

go to C:\Program Files\Android\Android Studio\plugins\android\lib\templates\activities\common\root\res\layout

i.e. the file directory where you have installed android studio.

then

copy simple.xml from another place just for backup

after that

open simple.xml file and replace it's code as bellow

<?xml version="1.0" encoding="utf-8"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${packageName}.${activityClass}">



</RelativeLayout>

but if you just want to change this project layout, just go to activity_main.xml and then go to text and post upper code to there

You may try CScope + tceetree + Graphviz.

Since API level 23 there is getContext() but if you want to support older versions you can use getActivity().getApplicationContext() while I still recommend using the support version of Fragment which is android.support.v4.app.Fragment.

want to use model in view as:

{{ Product::find($id) }}

you can use in view:

<?php
$tmp = \App\Product::find($id);
?>
{{ $tmp->name }}

Hope this will help you

If you want to keep it simple go ahead and try this out.

$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
        $count = $row[0];

The rest is up to you. If you have result comming from two tables i suggest you try a different approach.

The following is a decent solution across Unix/Linux installations, that does not rely on any unusual program features. This supports a multi-line message body, multiple attachments, and all the other typical features of mailx.

Unfortunately, it does not fit on a single line.

#!/bin/ksh

# Get the date stamp for temporary files
DT_STAMP=`date +'%C%y%m%d%H%M%S'`

# Create a multi-line body
echo "here you put the message body
which can be split across multiple lines!
woohoo!
" > body-${DT_STAMP}.mail

# Add several attachments
uuencode File1.pdf File1.pdf >  attachments-${DT_STAMP}.mail
uuencode File2.pdf File2.pdf >> attachments-${DT_STAMP}.mail

# Put everything together and send it off!
cat body-${DT_STAMP}.mail attachments-${DT_STAMP}.mail > out-${DT_STAMP}.mail
mailx -s "here you put the message subject" [email protected] < out-${DT_STAMP}.mail

# Clean up temporary files
rm body-${DT_STAMP}.mail
rm attachments-${DT_STAMP}.mail
rm out-${DT_STAMP}.mail

Fix: Move your project folder closer to the root of your disk

Don't:// folder/folder/folder/folder/very_long_folder_name/MyProject...

Do://folder/short_name/MyProject

Another reason could be duplicated resources or name spaces

Example:

  <style name="MyButton" parent="android:Widget.Button">
      <item name="android:textColor">@color/accent_color</item>
      <item name="android:textColor">#000000</item>
  </style>

And make sure all file names and extensions are in lowercase

myImage.png

Correct

how will I know that some tables are locked?

You can use SHOW OPEN TABLES command to view locked tables.

how do I unlock tables manually?

If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.

This works for me when you have jquery ui dropdown

if (navigator.userAgent.match(/(iPod|iPhone|iPad)/)) {

}

I had a similar scenario, but was also required to set a Proxy. The simplest way I could see to do this was to extend the SimpleClientHttpRequestFactory for the ease of setting the proxy (different proxies for non-prod vs prod). This should still work even if you don't require the proxy though. Then in my extended class I override the openConnection(URL url, Proxy proxy) method, using the same as the source, but just setting the timeouts before returning.

@Override
protected HttpURLConnection openConnection(URL url, Proxy proxy) throws IOException {
    URLConnection urlConnection = proxy != null ? url.openConnection(proxy) : url.openConnection();
    Assert.isInstanceOf(HttpURLConnection.class, urlConnection);
    urlConnection.setConnectTimeout(5000);
    urlConnection.setReadTimeout(5000);
    return (HttpURLConnection) urlConnection;
}

My use case might be a bit different but thought it might be useful to post a solution I came up with as it takes a different approach.

Essentially I have a third party Popover component that takes an anchor DOM element as a prop. The problem is that I cannot guarantee that the anchor element will be there immediately because the anchor element becomes visible at the same time as the Popover I want to anchor to it (during the same redux dispatch).

One possible fix was to place the Popover element deeper into the component tree than the element it was to be anchored too. However, that didn't fit nicely with the logical structure of my components.

Ultimately I decided to delay the (re)render of the Popover component a little bit to ensure that the anchor DOM element can be found. It uses the function as a child pattern to only render the children after a fixed delay:

import { Component } from 'react'
import PropTypes from 'prop-types'

export default class DelayedRender extends Component {
    componentDidMount() {
        this.t1 = setTimeout(() => this.forceUpdate(), 1500)
    }

    componentWillReceiveProps() {
        this.t2 = setTimeout(() => this.forceUpdate(), 1500)
    }

    shouldComponentUpdate() {
        return false
    }

    componentWillUnmount() {
        clearTimeout(this.t1)
        clearTimeout(this.t2)
    }

    render() {
        return this.props.children()
    }
}

DelayedRender.propTypes = {
    children: PropTypes.func.isRequired
}

It can be used like this:

<DelayedRender>
    {() =>
        <Popover anchorEl={getAnchorElement()}>
            <div>Hello!</div>
        </Popover>
    )}}
</DelayedRender>

Feels pretty hacky to me but works for my use case nevertheless.

You can use the values() method on the dict you got from the Django model field you make the queries on and then you can easily access each field by a index value.

Call it like this -

myList = dictOfSomeData.values()
itemNumberThree = myList[2] #If there's a value in that index off course...

You can use the response.text to write to a file:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("resp_text.txt", "w")
file.write(response.text)
file.close()
file = open("resp_content.txt", "w")
file.write(response.text)
file.close()

In Python 3.x, you can convert an integer value (including large ones, which the other answers don't allow for) into a series of bytes like this:

import math

x = 0x1234
number_of_bytes = int(math.ceil(x.bit_length() / 8))

x_bytes = x.to_bytes(number_of_bytes, byteorder='big')

x_int = int.from_bytes(x_bytes, byteorder='big')
x == x_int

If you are using an array of objects. Then the below code should do the magic, where an object property will be the criteria to remove duplicate items.

In the below example, duplicates have been removed comparing name of each item.

Try this example. http://jsfiddle.net/deepak7641/zLj133rh/

var myArray = [_x000D_
  {name: 'deepak', place: 'bangalore'}, _x000D_
  {name: 'chirag', place: 'bangalore'}, _x000D_
  {name: 'alok', place: 'berhampur'}, _x000D_
  {name: 'chandan', place: 'mumbai'}_x000D_
];_x000D_
var toRemove = [_x000D_
  {name: 'deepak', place: 'bangalore'},_x000D_
  {name: 'alok', place: 'berhampur'}_x000D_
];_x000D_
_x000D_
for( var i=myArray.length - 1; i>=0; i--){_x000D_
  for( var j=0; j<toRemove.length; j++){_x000D_
      if(myArray[i] && (myArray[i].name === toRemove[j].name)){_x000D_
      myArray.splice(i, 1);_x000D_
     }_x000D_
    }_x000D_
}_x000D_
_x000D_
alert(JSON.stringify(myArray));

You can do it like this.

Models.TestModels obj = new Models.TestModels();
foreach (var item in obj.sp)
{
    Console.Write(item.Key);
    Console.Write(item.Value.name);
    Console.Write(item.Value.age);
}

The problem you most likely have right now is that the collection is private. If you add public to the beginning of this line

Dictionary<int, dynamic> sp = new Dictionary<int, dynamic> 

You should be able to access it from the function inside your controller.

Edit: Adding functional example of the full TestModels implementation.

Your TestModels class should look something like this.

public class TestModels
{
    public Dictionary<int, dynamic> sp = new Dictionary<int, dynamic>();

    public TestModels()
    {
        sp.Add(0, new {name="Test One", age=5});
        sp.Add(1, new {name="Test Two", age=7});
    }
}

You probably want to read up on the dynamic keyword as well.

I'm new so I can't comment but thought to share the lazy fix. I use Pedram's original approach as well, and just ran into the same Lollipop issue. But alanv over in another post had a one line fix. Its some kind of bug or oversight in API21. Literally just add android:useLevel="true" to your circle progress xml. Pedram's new approach is still the proper fix, but I just thought I share the lazy fix as well.

You need to put arguments before my_script.R and use - on the arguments, e.g.

R CMD BATCH -blabla my_script.R

commandArgs() will receive -blabla as a character string in this case. See the help for details:

$ R CMD BATCH --help
Usage: R CMD BATCH [options] infile [outfile]

Run R non-interactively with input from infile and place output (stdout
and stderr) to another file.  If not given, the name of the output file
is the one of the input file, with a possible '.R' extension stripped,
and '.Rout' appended.

Options:
  -h, --help        print short help message and exit
  -v, --version     print version info and exit
  --no-timing           do not report the timings
  --            end processing of options

Further arguments starting with a '-' are considered as options as long
as '--' was not encountered, and are passed on to the R process, which
by default is started with '--restore --save --no-readline'.
See also help('BATCH') inside R.

You need seek to the beginning of the file before writing and then use file.truncate() if you want to do inplace replace:

import re

myfile = "path/test.xml"

with open(myfile, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))
    f.truncate()

The other way is to read the file then open it again with open(myfile, 'w'):

with open(myfile, "r") as f:
    data = f.read()

with open(myfile, "w") as f:
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))

Neither truncate nor open(..., 'w') will change the inode number of the file (I tested twice, once with Ubuntu 12.04 NFS and once with ext4).

By the way, this is not really related to Python. The interpreter calls the corresponding low level API. The method truncate() works the same in the C programming language: See http://man7.org/linux/man-pages/man2/truncate.2.html

Do I really have to create an NSString for "Wrong"?

No, why not just do:

if([statusString isEqualToString:@"Wrong"]){
    //doSomething;
}

Using @"" simply creates a string literal, which is a valid NSString.

Also, can I compare the value of a UILabel.text to a string without assigning the label value to a string?

Yes, you can do something like:

UILabel *label = ...;
if([someString isEqualToString:label.text]) {
    // Do stuff here 
}

These link in the libraries selected in MSVC++.

You can check if the index of the selected value is 0 or -1 using the selectedIndex property.

In your case 0 is also not a valid index value because its the "placeholder":
<option value="selectcard">--- Please select ---</option>

LIVE DEMO

function Validate()
 {
   var combo = document.getElementById("cardtype");
   if(combo.selectedIndex <=0)
    {
      alert("Please Select Valid Value");
    }
 }

Assuming the destination array has enough space, Array.Copy() will work. You might also try using a List<T> and its .AddRange() method.

you can't initialise var with null, var needs to be initialised as a type otherwise it cannot be inferred, if you think you need to do this maybe you can post the code it is probable that there is another way to do what you are attempting.

it solved me by adjusting code from @Connor Cushion Mulhall by

iframe, object, embed {_x000D_
  width: 100%;_x000D_
  display: block !important;_x000D_
}

Install

• Ctrl+P, write ext install npm script runner
• Restart VS Code

Use (two ways)

• Ctrl+R Shift+R
• Ctrl+P, write >npm, select run script, select the desired task

Update: Since version 1.3 Visual Studio Code has integrated terminal. To open it, use any of these methods:

• Use the Ctrl+` keyboard shortcut.
• Use the View | Toggle Integrated Terminal menu command.
• From the Command Palette (Ctrl+Shift+P), use the View:Toggle Integrated Terminal command.

I always do it this very simple way without messing with timestamps:

var fps, eachNthFrame, frameCount;

fps = 30;

//This variable specifies how many frames should be skipped.
//If it is 1 then no frames are skipped. If it is 2, one frame 
//is skipped so "eachSecondFrame" is renderd.
eachNthFrame = Math.round((1000 / fps) / 16.66);

//This variable is the number of the current frame. It is set to eachNthFrame so that the 
//first frame will be renderd.
frameCount = eachNthFrame;

requestAnimationFrame(frame);

//I think the rest is self-explanatory
fucntion frame() {
  if (frameCount == eachNthFrame) {
    frameCount = 0;
    animate();
  }
  frameCount++;
  requestAnimationFrame(frame);
}

Insert a column, for instance a new A column. Then use this function;

="k"&B1

and copy it down.

Then you can hide the new column A if you need too.

simple if u are using php Just append the current time at the end of the css like

<link href="css/name.css?<?php echo 
time(); ?>" rel="stylesheet">

So now everytime u reload whatever it is , the time changes and browser thinks its a different file since the last bit keeps changing.... U can do this for any file u force the browser to always refresh using whatever scripting language u want

Short answer: Right-click on the class that contains the main method. Click on "Run As". Click on "Java Application". The keyboard shortcut is: Shift+Alt+X J (while holding Shift and Alt, press X; then release Shift and Alt and press J).

Long answer: To be honest, I am not 100% sure why this problem happens. It might be because of using a different jdk. I faced the same error. The solution was easier than I imagined. I was used to running my code using Ctrl + F11. But when I ran it as a java application (the way I described in "short answer"), the problem was resolved. I am not sure if it solves other people's problems as well, but it is worthwhile to try. :)

In my case, it was a misconfigured IntelliJ instance.

Project Structure -> SDKs -> Remove and add the Java SDK again

It works for me if I tick the box 'Prompt for workspace on startup', which you find in Window > Preferences > General > Startup and Shutdown > Workspaces.

This solution demonstrates how to transform data with Spark native functions which are better than UDFs. It also demonstrates how dropDuplicates which is more suitable than distinct for certain queries.

Suppose you have this DataFrame:

+-------+-------------+
|country|    continent|
+-------+-------------+
|  china|         asia|
| brazil|south america|
| france|       europe|
|  china|         asia|
+-------+-------------+

Here's how to take all the distinct countries and run a transformation:

df
  .select("country")
  .distinct
  .withColumn("country", concat(col("country"), lit(" is fun!")))
  .show()

+--------------+
|       country|
+--------------+
|brazil is fun!|
|france is fun!|
| china is fun!|
+--------------+

You can use dropDuplicates instead of distinct if you don't want to lose the continent information:

df
  .dropDuplicates("country")
  .withColumn("description", concat(col("country"), lit(" is a country in "), col("continent")))
  .show(false)

+-------+-------------+------------------------------------+
|country|continent    |description                         |
+-------+-------------+------------------------------------+
|brazil |south america|brazil is a country in south america|
|france |europe       |france is a country in europe       |
|china  |asia         |china is a country in asia          |
+-------+-------------+------------------------------------+

See here for more information about filtering DataFrames and here for more information on dropping duplicates.

Ultimately, you'll want to wrap your transformation logic in custom transformations that can be chained with the Dataset#transform method.

This works for me in Visual Studio 2015.

I copy all DLL files from a folder located in a library folder on the same level as my solution folder into the targetdirectory of the project being built.

Using a relative path from my project directory and going up the folder structure two steps with..\..\lib

MySolutionFolder
....MyProject
Lib

if $(ConfigurationName) == Debug (
xcopy /Y "$(ProjectDir)..\..\lib\*.dll" "$(TargetDir)"
) ELSE (echo "Not Debug mode, no file copy from lib")

"If you use ng-model, you have to have a dot in there."
Make your model point to an object.property and you'll be good to go.

Controller

$scope.formData = {};
$scope.check = function () {
  console.log($scope.formData.searchText.$modelValue); //works
}

Template

<input ng-model="formData.searchText"/>
<button ng-click="check()">Check!</button>

This happens when child scopes are in play - like child routes or ng-repeats. The child-scope creates it's own value and a name conflict is born as illustrated here:

See this video clip for more: https://www.youtube.com/watch?v=SBwoFkRjZvE&t=3m15s

A very simple method would be to use the extract method to select all the digits. Simply supply it the regular expression '\d+' which extracts any number of digits.

df['result'] = df.result.str.extract(r'(\d+)', expand=True).astype(int)
df

    time  result
1  09:00      52
2  10:00      62
3  11:00      44
4  12:00      30
5  13:00     110

If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template and add config.php to your .gitignore.

Having 2 files like you suggested would be the easiest solution.

For instance:

2 files solution:

index.html

(.. your html ..)
<form action="script.php" method="get">
  <input type="submit" value="Run me now!">
</form>
(...)

script.php

<?php
  echo "Hello world!"; // Your code here
?>

Single file solution:

index.php

<?php
  if (!empty($_GET['act'])) {
    echo "Hello world!"; //Your code here
  } else {
?>
(.. your html ..)
<form action="index.php" method="get">
  <input type="hidden" name="act" value="run">
  <input type="submit" value="Run me now!">
</form>
<?php
  }
?>
