I found a very basic example of List comparison at List Compare This example verifies the size first and then checks the availability of the particular element of one list in another.

Here is a slightly different answer. Your column names & lengths may all match, but perhaps you are specifying the columns in the wrong order in your SELECT statement. Say tableX and tableY have columns with the same name, but in different order

They are format specifiers. They are used when you want to include the value of your Python expressions into strings, with a specific format enforced.

See Dive into Python for a relatively detailed introduction.

Replace:

Response.Write("<script language=javascript>alert('ERROR');</script>);

With

Response.Write("<script language=javascript>alert('ERROR');</script>");

In other words, you're missing a closing " at the end of the Response.Write statement.

It's worth mentioning that the code shown in the screenshot appears to correctly contain a closing double quote, however your best bet overall would be to use the ClientScriptManager.RegisterScriptBlock method:

var clientScript = Page.ClientScript;
clientScript.RegisterClientScriptBlock(this.GetType(), "AlertScript", "alert('ERROR')'", true);

This will take care of wrapping the script with <script> tags and writing the script into the page for you.

Don't have long values as primary key. That will destroy your performance. See the mysql manual, section 13.6.13 'InnoDB Performance Tuning and Troubleshooting'.

Instead, have a surrogate int key as primary (with auto_increment), and your loong key as a secondary UNIQUE.

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

Contains(s2) is many times (in my computer 10 times) faster than IndexOf(s2) because Contains uses StringComparison.Ordinal that is faster than the culture sensitive search that IndexOf does by default (but that may change in .net 4.0 http://davesbox.com/archive/2008/11/12/breaking-changes-to-the-string-class.aspx).

Contains has exactly the same performance as IndexOf(s2,StringComparison.Ordinal) >= 0 in my tests but it's shorter and makes your intent clear.

For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?

'Date' is your index so you want to do,

print (df.index.min())
print (df.index.max())

fist get the certificate from the provider
create a file ends wirth .cer and pase the certificate

copy the text file or  past   it  somewhere you can access it 
then use the cmd prompt as an admin and cd to the bin of the jdk,
the cammand that will be used is the:  keytool 

change the  password of the keystore with :

keytool  -storepasswd -keystore "path of the key store from c\ and down"

the password is : changeit 
 then you will be asked to enter the new password twice 

then type the following :

Regarding jQuery, the following common methods will also remove other constructs such as data and event handlers:

remove()

In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

empty()

To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.

html()

Additionally, jQuery removes other constructs such as data and event handlers from child elements before replacing those elements with the new content.

I tried the above solution but I found it unsuitable for large amounts of data. I then discovered the stream feature:

MongoClient.connect("...", function(err, db){
    var c = db.collection('yourCollection');
    var s = c.find({/* your query */}).stream();
    s.on('data', function(doc){
        c.update({_id: doc._id}, {$set: {name : doc.firstName + ' ' + doc.lastName}}, function(err, result) { /* result == true? */} }
    });
    s.on('end', function(){
        // stream can end before all your updates do if you have a lot
    })
})

I had the same issue, i was able to solve it by changing the Port number.

1. Right click on the project and select properties

2. Go to the Debug section

3. Under Web Server Settings change App URL port [just increase by one :)]

Check your windows task manager and make sure you kill all chrome processes before running the command.

I didn't understand how the accepted answer answers the actual question of how to run any commands on the server after sshpass is given from within the bash script file. For that reason, I'm providing an answer.

After your provided script commands, execute additional commands like below:

sshpass -p 'password' ssh user@host "ls; whois google.com;" #or whichever commands you would like to use, for multiple commands provide a semicolon ; after the command

In your script:

#! /bin/bash

sshpass -p 'password' ssh user@host "ls; whois google.com;"

Install the additional module tablefunc once per database, which provides the function crosstab(). Since Postgres 9.1 you can use CREATE EXTENSION for that:

CREATE EXTENSION IF NOT EXISTS tablefunc;

Improved test case

CREATE TABLE tbl (
   section   text
 , status    text
 , ct        integer  -- "count" is a reserved word in standard SQL
);

INSERT INTO tbl VALUES 
  ('A', 'Active', 1), ('A', 'Inactive', 2)
, ('B', 'Active', 4), ('B', 'Inactive', 5)
                    , ('C', 'Inactive', 7);  -- ('C', 'Active') is missing

Simple form - not fit for missing attributes

crosstab(text) with 1 input parameter:

SELECT *
FROM   crosstab(
   'SELECT section, status, ct
    FROM   tbl
    ORDER  BY 1,2'  -- needs to be "ORDER BY 1,2" here
   ) AS ct ("Section" text, "Active" int, "Inactive" int);

Returns:

 Section | Active | Inactive
---------+--------+----------
 A       |      1 |        2
 B       |      4 |        5
 C       |      7 |           -- !!

• No need for casting and renaming.
• Note the incorrect result for C: the value 7 is filled in for the first column. Sometimes, this behavior is desirable, but not for this use case.
• The simple form is also limited to exactly three columns in the provided input query: row_name, category, value. There is no room for extra columns like in the 2-parameter alternative below.

Safe form

crosstab(text, text) with 2 input parameters:

SELECT *
FROM   crosstab(
   'SELECT section, status, ct
    FROM   tbl
    ORDER  BY 1,2'  -- could also just be "ORDER BY 1" here

  , $$VALUES ('Active'::text), ('Inactive')$$
   ) AS ct ("Section" text, "Active" int, "Inactive" int);

Returns:

 Section | Active | Inactive
---------+--------+----------
 A       |      1 |        2
 B       |      4 |        5
 C       |        |        7  -- !!

• Note the correct result for C.

• The second parameter can be any query that returns one row per attribute matching the order of the column definition at the end. Often you will want to query distinct attributes from the underlying table like this:

  'SELECT DISTINCT attribute FROM tbl ORDER BY 1'
  

  That's in the manual.

  Since you have to spell out all columns in a column definition list anyway (except for pre-defined crosstabN() variants), it is typically more efficient to provide a short list in a VALUES expression like demonstrated:

  $$VALUES ('Active'::text), ('Inactive')$$)
  

  Or (not in the manual):

  $$SELECT unnest('{Active,Inactive}'::text[])$$  -- short syntax for long lists
  

• I used dollar quoting to make quoting easier.

• You can even output columns with different data types with crosstab(text, text) - as long as the text representation of the value column is valid input for the target type. This way you might have attributes of different kind and output text, date, numeric etc. for respective attributes. There is a code example at the end of the chapter crosstab(text, text) in the manual.

db<>fiddle here

Advanced examples

• Pivot on Multiple Columns using Tablefunc - also demonstrating mentioned "extra columns"

• Dynamic alternative to pivot with CASE and GROUP BY

\crosstabview in psql

Postgres 9.6 added this meta-command to its default interactive terminal psql. You can run the query you would use as first crosstab() parameter and feed it to \crosstabview (immediately or in the next step). Like:

db=> SELECT section, status, ct FROM tbl \crosstabview

Similar result as above, but it's a representation feature on the client side exclusively. Input rows are treated slightly differently, hence ORDER BY is not required. Details for \crosstabview in the manual. There are more code examples at the bottom of that page.

Related answer on dba.SE by Daniel Vérité (the author of the psql feature):

• How do I generate a pivoted CROSS JOIN where the resulting table definition is unknown?

The previously accepted answer is outdated.

• The variant of the function crosstab(text, integer) is outdated. The second integer parameter is ignored. I quote the current manual:

  crosstab(text sql, int N) ...

  Obsolete version of crosstab(text). The parameter N is now ignored, since the number of value columns is always determined by the calling query

• Needless casting and renaming.

• It fails if a row does not have all attributes. See safe variant with two input parameters above to handle missing attributes properly.

• ORDER BY is required in the one-parameter form of crosstab(). The manual:

  In practice the SQL query should always specify ORDER BY 1,2 to ensure that the input rows are properly ordered

There are many cases (such as an infinite list or a very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users of facebook with their details, or all the items on ebay.

The difference is that "List" objects are stored "right here and right now", whereas "IEnumerable" objects work "just one at a time". So if I am going through all the items on ebay, one at a time would be something even a small computer can handle, but ".ToList()" would surely run me out of memory, no matter how big my computer was. No computer can by itself contain and handle such a huge amount of data.

[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable<long> primes, which for obvious reasons also contains a SortedList<long> _primes. all the primes calculated so far. the next prime to be checked would only be run against the existing primes (up to the square root). That way you gain both - primes one at a time (IEnumerable) and a good list of "primes so far", which is a pretty good approximation of the entire (infinite) list.

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Check out your TNS Names, this must not have spaces at the left side of the ALIAS

One more way:

j=i[0]
for k in range(1,len(i)):
    j = numpy.vstack([j,i[k]])

In this case j will be a numpy array

dim mydate = from cv in mydata.t1s
  select cv.date1 asc

datetime mindata = mydate[0];

It will be:

The answers here do an excellent job in defining both monoids and monads, however, they still don't seem to answer the question:

And on a less important note, is this true and if so could you give an explanation (hopefully one that can be understood by someone who doesn't have much Haskell experience)?

The crux of the matter that is missing here, is the different notion of "monoid", the so-called categorification more precisely -- the one of monoid in a monoidal category. Sadly Mac Lane's book itself makes it very confusing:

All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.

Main confusion

Why is this confusing? Because it does not define what is "monoid in the category of endofunctors" of X. Instead, this sentence suggests taking a monoid inside the set of all endofunctors together with the functor composition as binary operation and the identity functor as a monoidal unit. Which works perfectly fine and turns into a monoid any subset of endofunctors that contains the identity functor and is closed under functor composition.

Yet this is not the correct interpretation, which the book fails to make clear at that stage. A Monad f is a fixed endofunctor, not a subset of endofunctors closed under composition. A common construction is to use f to generate a monoid by taking the set of all k-fold compositions f^k = f(f(...)) of f with itself, including k=0 that corresponds to the identity f^0 = id. And now the set S of all these powers for all k>=0 is indeed a monoid "with product × replaced by composition of endofunctors and unit set by the identity endofunctor".

And yet:

• This monoid S can be defined for any functor f or even literally for any self-map of X. It is the monoid generated by f.
• The monoidal structure of S given by the functor composition and the identity functor has nothing do with f being or not being a monad.

And to make things more confusing, the definition of "monoid in monoidal category" comes later in the book as you can see from the table of contents. And yet understanding this notion is absolutely critical to understanding the connection with monads.

(Strict) monoidal categories

Going to Chapter VII on Monoids (which comes later than Chapter VI on Monads), we find the definition of the so-called strict monoidal category as triple (B, *, e), where B is a category, *: B x B-> B a bifunctor (functor with respect to each component with other component fixed) and e is a unit object in B, satisfying the associativity and unit laws:

(a * b) * c = a * (b * c)
a * e = e * a = a

for any objects a,b,c of B, and the same identities for any morphisms a,b,c with e replaced by id_e, the identity morphism of e. It is now instructive to observe that in our case of interest, where B is the category of endofunctors of X with natural transformations as morphisms, * the functor composition and e the identity functor, all these laws are satisfied, as can be directly verified.

What comes after in the book is the definition of the "relaxed" monoidal category, where the laws only hold modulo some fixed natural transformations satisfying so-called coherence relations, which is however not important for our cases of the endofunctor categories.

Monoids in monoidal categories

Finally, in section 3 "Monoids" of Chapter VII, the actual definition is given:

A monoid c in a monoidal category (B, *, e) is an object of B with two arrows (morphisms)

mu: c * c -> c
nu: e -> c

making 3 diagrams commutative. Recall that in our case, these are morphisms in the category of endofunctors, which are natural transformations corresponding to precisely join and return for a monad. The connection becomes even clearer when we make the composition * more explicit, replacing c * c by c^2, where c is our monad.

Finally, notice that the 3 commutative diagrams (in the definition of a monoid in monoidal category) are written for general (non-strict) monoidal categories, while in our case all natural transformations arising as part of the monoidal category are actually identities. That will make the diagrams exactly the same as the ones in the definition of a monad, making the correspondence complete.

Conclusion

In summary, any monad is by definition an endofunctor, hence an object in the category of endofunctors, where the monadic join and return operators satisfy the definition of a monoid in that particular (strict) monoidal category. Vice versa, any monoid in the monoidal category of endofunctors is by definition a triple (c, mu, nu) consisting of an object and two arrows, e.g. natural transformations in our case, satisfying the same laws as a monad.

Finally, note the key difference between the (classical) monoids and the more general monoids in monoidal categories. The two arrows mu and nu above are not anymore a binary operation and a unit in a set. Instead, you have one fixed endofunctor c. The functor composition * and the identity functor alone do not provide the complete structure needed for the monad, despite that confusing remark in the book.

Another approach would be to compare with the standard monoid C of all self-maps of a set A, where the binary operation is the composition, that can be seen to map the standard cartesian product C x C into C. Passing to the categorified monoid, we are replacing the cartesian product x with the functor composition *, and the binary operation gets replaced with the natural transformation mu from c * c to c, that is a collection of the join operators

join: c(c(T))->c(T)

for every object T (type in programming). And the identity elements in classical monoids, which can be identified with images of maps from a fixed one-point-set, get replaced with the collection of the return operators

return: T->c(T) 

But now there are no more cartesian products, so no pairs of elements and thus no binary operations.

If you don't want the image to affect the layout at all (and float on top of other content) you can apply the following CSS to the image:

position:absolute;
right:0;
top:0;

If you want it to float at the right of a particular parent section, you can add position: relative to that section.

Not sure why no one says the obvious, as there's a built in javascript scrollTo function:

scrollTo( $('#element').position().top );

Reference.

I found the same problem. I did the following:

docker run -ti devops -v /tmp:/tmp /bin/bash

When I change it to

docker run -ti -v /tmp:/tmp devops /bin/bash

it works fine.

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

same way you do it in javascript:

"something".length

Use ng-value instead of value.

ng-value="true"

Version with ng-checked is worse because of the code duplication.

You have to create either another page or generic handler with the code to generate your pdf. Then that event gets triggered and the person is redirected to that page.

You try this.

I have already tried it in my django template.

It will work fine. Just remove the curly braces pair {{ and }} from {{source}}.

I have also added <table> tag and that's it.

After modification your code will look something like below.

{% for source in sources %}
   <table>
      <tr>
          <td>{{ source }}</td>
          <td>
              {% if title == source %}
                Just now! 
              {% endif %}
          </td>
      </tr>
   </table>
{% endfor %}

My dictionary looks like below,

{'title':"Rishikesh", 'sources':["Hemkesh", "Malinikesh", "Rishikesh", "Sandeep", "Darshan", "Veeru", "Shwetabh"]}

and OUTPUT looked like below once my template got rendered.

Hemkesh 
Malinikesh  
Rishikesh   Just now!
Sandeep 
Darshan 
Veeru   
Shwetabh    

This answer explains what's going on behind the scenes, and the basics of how to solve this problem in any language. For reference, see the MDN docs on this topic.

You are making a request for a URL from JavaScript running on one domain (say domain-a.com) to an API running on another domain (domain-b.com). When you do that, the browser has to ask domain-b.com if it's okay to allow requests from domain-a.com. It does that with an HTTP OPTIONS request. Then, in the response, the server on domain-b.com has to give (at least) the following HTTP headers that say "Yeah, that's okay":

HTTP/1.1 204 No Content                            // or 200 OK
Access-Control-Allow-Origin: https://domain-a.com  // or * for allowing anybody
Access-Control-Allow-Methods: POST, GET, OPTIONS   // What kind of methods are allowed
...                                                // other headers

If you're in Chrome, you can see what the response looks like by pressing F12 and going to the "Network" tab to see the response the server on domain-b.com is giving.

So, back to the bare minimum from @threeve's original answer:

header := w.Header()
header.Add("Access-Control-Allow-Origin", "*")

if r.Method == "OPTIONS" {
    w.WriteHeader(http.StatusOK)
    return
}

This will allow anybody from anywhere to access this data. The other headers he's included are necessary for other reasons, but these headers are the bare minimum to get past the CORS (Cross Origin Resource Sharing) requirements.

To answer also to the comment by @MLT, there is an alternative to the standard cases environment, not too sophisticated really, with both lines numbered. This code:

\documentclass{article}
\usepackage{amsmath}
\usepackage{cases}

\begin{document}

\begin{numcases}{f(x)=}
  1, & if $x<0$\\
  0, & otherwise
\end{numcases}

\end{document}

produces

Notice that here, math must be delimited by \(...\) or $...$, at least on the right of & in each line (reference).

a straightforward one-line solution:
requires Java 8

Collections.nCopies( 3, "abc" ).stream().collect( Collectors.joining() );

DateTime now = DateTime.Now;
int prevMonth = now.AddMonths(-1).Month;
int year = now.AddMonths(-1).Year;
int daysInPrevMonth = DateTime.DaysInMonth(year, prevMonth);
DateTime firstDayPrevMonth = new DateTime(year, prevMonth, 1);
DateTime lastDayPrevMonth = new DateTime(year, prevMonth, daysInPrevMonth);
Console.WriteLine("{0} {1}", firstDayPrevMonth.ToShortDateString(),
  lastDayPrevMonth.ToShortDateString());

• Write the file while editing - :w newname - to create a copy.
• Start editing the new copy - :e#.
• (Optionally) remove the old copy - :!rm oldname.

On Windows, the optional 3rd step changes a little:

• (Optionally) remove old Windows copy - :!del oldname.

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>

I'm not familiar with the async keyword (is this specific to Silverlight or a new feature in the beta version of Visual Studio?), but I think I can give you an idea of why you can't do this.

If I do:

var o = new MyObject();
MessageBox(o.SomeProperty.ToString());

o may not be done initializing before the next line of code runs. An instantiation of your object cannot be assigned until your constructor is completed, and making the constructor asynchronous wouldn't change that so what would be the point? However, you could call an asynchronous method from your constructor and then your constructor could complete and you would get your instantiation while the async method is still doing whatever it needs to do to setup your object.

Use trim and val.

var value=$.trim($("#spa").val());

if(value.length>0)
{
 //do some stuffs. 
}

val() : return the value of the input.

trim(): will trim the white spaces.

List<String> sids = new ArrayList<String>();
List<String> lids = new ArrayList<String>();

String query = "SELECT rlink_id, COUNT(*)"
             + "FROM dbo.Locate  "
             + "GROUP BY rlink_id ";

Statement stmt = yourconnection.createStatement();
try {
    ResultSet rs4 = stmt.executeQuery(query);

    while (rs4.next()) {
        sids.add(rs4.getString(1));
        lids.add(rs4.getString(2));
    }
} finally {
    stmt.close();
}

String show[] = sids.toArray(sids.size());
String actuate[] = lids.toArray(lids.size());

I kind of fail to see the point, for jqGrid you can use the virtual scrolling functionality:

http://www.trirand.net/aspnetmvc/grid/performancevirtualscrolling

but then again, millions of rows with filtering can be done:

http://www.trirand.net/aspnetmvc/grid/performancelinq

I really fail to see the point of "as if there are no pages" though, I mean... there is no way to display 1,000,000 rows at once in the browser - this is 10MB of HTML raw, I kind of fail to see why users would not want to see the pages.

Anyway...

I did something like that:

HTML:

<p class='parent'>text text text</p>
<img class='child' src='idk.png'>

CSS:

.child {
    visibility: hidden;
}

.parent:hover .child {
    visibility: visible;
}

As @Kanishka said , if we disable a form element it will not be submitted . I have created a snippet for this problem . When the select element is disabled it creates a hidden input field and store the value . When it is enabled it delete the created hidden input fields .

The method you are trying to use checks if the button is active:

btnAdd.isEnabled()

When enabled, any component associated with this object is active and able to fire this object's actionPerformed method.

This method does not check if the button is pressed.

If i understand your question correctly, you want to disable your "Add" button after the user clicks "Check out".

Try disabling your button at start: btnAdd.setEnabled(false) or after the user presses "Check out"

If you are totally new to python read step by step or go directly to 5th step directly. Follow the below method to install scipy 0.18.1 on Windows 64-bit , Python 64-bit . Be careful with the versions of 1. Python 2. Windows 3. .whl version of numpy and scipy files 4. First install numpy and then scipy.

pip install FileName.whl

5. ForNumpy:http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy ForScipy:http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

Be aware of the file name ( what I mean is check the cp no). Ex :scipy-0.18.1-cp35-cp35m-win_amd64.whl To check which cp is supported by your pip , go to point No 2 below.

If you are using .whl file . Following errors are likely to occur .

1. You are using pip version 7.1.0, however version 8.1.2 is available.

You should consider upgrading via the 'python -m pip install --upgrade pip' command

2. scipy-0.15.1-cp33-none-win_amd64.whl.whl is not supported wheel on this platform

For the above error : start Python(in my case 3.5), type : import pip print(pip.pep425tags.get_supported())

output :

[('cp35', 'cp35m', 'win_amd64'), ('cp35', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'), ('cp35', 'none', 'any'), ('cp3', 'none', 'any'), ('py35', 'none', 'any'), ('py3', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]

In the output you will observe cp35 is there , so download cp35 for numpy as well as scipy. Further edits are most welcome !!!!

It should be

<input type="image" id="myimage" src="[...]" />

So "image" instead of "submit". It will still be a button which submits on click.

If your image is bigger than the button which is shown; let's say the image is 200x200 pixels; add this to your stylesheet:

#myimage {
    height: 200px;
    width: 200px;
}

or directly in the button tag:

<input type="image" id="myimage" style="height:200px;width:200px;" src="[...]" />

Note however that resizing the image like this might not yield ideal results; if e.g. your image is much smaller than you want it to be shown, you will see the single pixels; if on the other hand it is much bigger, you are wasting precious bandwidth of your users. So resizing the picture itself to the actual size is preferrable over rescaling via stylesheets!

I know this is an old question, but I'm going to answer it because I have to disagree with all the answers here.

Now, I'll agree that most of the time you either want to do a plain throw, to preserve as much information as possible about what went wrong, or you want to throw a new exception that may contain that as an inner-exception, or not, depending on how likely you are to want to know about the inner events that caused it.

There is an exception though. There are several cases where a method will call into another method and a condition that causes an exception in the inner call should be considered the same exception on the outer call.

One example is a specialised collection implemented by using another collection. Let's say it's a DistinctList<T> that wraps a List<T> but refuses duplicate items.

If someone called ICollection<T>.CopyTo on your collection class, it might just be a straight call to CopyTo on the inner collection (if say, all the custom logic only applied to adding to the collection, or setting it up). Now, the conditions in which that call would throw are exactly the same conditions in which your collection should throw to match the documentation of ICollection<T>.CopyTo.

Now, you could just not catch the execption at all, and let it pass through. Here though the user gets an exception from List<T> when they were calling something on a DistinctList<T>. Not the end of the world, but you may want to hide those implementation details.

Or you could do your own checking:

public CopyTo(T[] array, int arrayIndex)
{
  if(array == null)
    throw new ArgumentNullException("array");
  if(arrayIndex < 0)
    throw new ArgumentOutOfRangeException("arrayIndex", "Array Index must be zero or greater.");
  if(Count > array.Length + arrayIndex)
    throw new ArgumentException("Not enough room in array to copy elements starting at index given.");
  _innerList.CopyTo(array, arrayIndex);
}

That's not the worse code because it's boilerplate and we can probably just copy it from some other implementation of CopyTo where it wasn't a simple pass-through and we had to implement it ourselves. Still, it's needlessly repeating the exact same checks that are going to be done in _innerList.CopyTo(array, arrayIndex), so the only thing it has added to our code is 6 lines where there could be a bug.

We could check and wrap:

public CopyTo(T[] array, int arrayIndex)
{
  try
  {
    _innerList.CopyTo(array, arrayIndex);
  }
  catch(ArgumentNullException ane)
  {
    throw new ArgumentNullException("array", ane);
  }
  catch(ArgumentOutOfRangeException aore)
  {
    throw new ArgumentOutOfRangeException("Array Index must be zero or greater.", aore);
  }
  catch(ArgumentException ae)
  {
    throw new ArgumentException("Not enough room in array to copy elements starting at index given.", ae);
  }
}

In terms of new code added that could potentially be buggy, this is even worse. And we don't gain a thing from the inner exceptions. If we pass a null array to this method and receive an ArgumentNullException, we're not going to learn anything by examining the inner exception and learning that a call to _innerList.CopyTo was passed a null array and threw an ArgumentNullException.

Here, we can do everything we want with:

public CopyTo(T[] array, int arrayIndex)
{
  try
  {
    _innerList.CopyTo(array, arrayIndex);
  }
  catch(ArgumentException ae)
  {
    throw ae;
  }
}

Every one of the exceptions that we expect to have to throw if the user calls it with incorrect arguments, will correctly be thrown by that re-throw. If there's a bug in the logic used here, it's in one of two lines - either we were wrong in deciding this was a case where this approach works, or we were wrong in having ArgumentException as the exception type looked for. It's the only two bugs that the catch block can possibly have.

Now. I still agree that most of the time you either want a plain throw; or you want to construct your own exception to more directly match the problem from the perspective of the method in question. There are cases like the above where re-throwing like this makes more sense, and there are plenty of other cases. E.g. to take a very different example, if an ATOM file reader implemented with a FileStream and an XmlTextReader receives a file error or invalid XML, then it will perhaps want to throw exactly the same exception it received from those classes, but it should look to the caller that it is AtomFileReader that is throwing a FileNotFoundException or XmlException, so they might be candidates for similarly re-throwing.

Edit:

We can also combine the two:

public CopyTo(T[] array, int arrayIndex)
{
  try
  {
    _innerList.CopyTo(array, arrayIndex);
  }
  catch(ArgumentException ae)
  {
    throw ae;
  }
  catch(Exception ex)
  {
    //we weren't expecting this, there must be a bug in our code that put
    //us into an invalid state, and subsequently let this exception happen.
    LogException(ex);
    throw;
  }
}

Just declare a default value for a field:

CREATE TABLE MyTable(
    ID INTEGER PRIMARY KEY,
    Name TEXT,
    Other STUFF,
    Timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
);

However, if your INSERT command explicitly sets this field to NULL, it will be set to NULL.

1. Open the AWS Console
2. Click on your username near the top right and select My Security Credentials
3. Click on Users in the sidebar
4. Click on your username
5. Click on the Security Credentials tab
6. Click Create Access Key
7. Click Show User Security Credentials

This will render depending components 3 times (arrays with equal elements aren't equal):

const [msg, setMsg] = useState([""])

setMsg(["test"])
setMsg(["test"])
setMsg(["test"])

you can update your war from the command line using java commands as mentioned here:

jar -uvf test.war yourclassesdir 

Other useful commands:

Command to unzip/explode the war file

jar -xvf test.war

Command to create the war file

jar -cvf test.war yourclassesdir 

Eg:

jar -cvf test.war *
jar -cvf test.war WEB-INF META-INF

By default there is no password is set for root user in XAMPP.

You can set password for root user of MySQL.

Navigate to

localhost:80/security/index.php

and set password for root user.

Note:Please change the port number in above url if your Apache in on different port.

Open XAMPP control panel Click "Shell" button

Command prompt window will open now in that window type

mysql -u root -p;

It will ask for password type the password which you have set for root user.

There you go ur logged in as root user :D Now do what u want to do :P

For giving placeholder a color just use these lines of code:

::-webkit-input-placeholder { color: red; }
::-moz-placeholder {color: red; }
:-ms-input-placeholder { color: red; } 
:-o-input-placeholder { color: red; } 

You can do it:

var str = "Doctor Who,Fantasy,Steven Moffat,David Tennant";

var title = str.Split(',').First();

Also you can do it this way:

var index = str.IndexOf(",");
var title = index < 0 ? str : str.Substring(0, index);

Use this

os.chdir('C:/Users\expoperialed\Desktop\Python')

It is just Value, not @value.. Try it. I'm not sure about @Model.title, maybe it's just Model.title

Use &:

foreach($arr as &$value) {
    $value = $newVal;
}

& passes a value of the array as a reference and does not create a new instance of the variable. Thus if you change the reference the original value will change.

PHP documentation for Passing by Reference

Edit 2018

This answer seems to be favored by a lot of people on the internet, which is why I decided to add more information and words of caution.
While pass by reference in foreach (or functions) is a clean and short solution, for many beginners this might be a dangerous pitfall.

1. Loops in PHP don't have their own scope. - @Mark Amery

   This could be a serious problem when the variables are being reused in the same scope. Another SO question nicely illustrates why that might be a problem.

2. As foreach relies on the internal array pointer in PHP 5, changing it within the loop may lead to unexpected behavior. - PHP docs for foreach.

   Unsetting a record or changing the hash value (the key) during the iteration on the same loop could lead to potentially unexpected behaviors in PHP < 7. The issue gets even more complicated when the array itself is a reference.

3. Foreach performance.
   In general, PHP prefers pass by value due to the copy-on-write feature. It means that internally PHP will not create duplicate data unless the copy of it needs to be changed. It is debatable whether pass by reference in foreach would offer a performance improvement. As it is always the case, you need to test your specific scenario and determine which option uses less memory and CPU time. For more information see the SO post linked below by NikiC.

4. Code readability.
   Creating references in PHP is something that quickly gets out of hand. If you are a novice and don't have full control of what you are doing, it is best to stay away from references. For more information about & operator take a look at this guide: Reference — What does this symbol mean in PHP?
   For those who want to learn more about this part of PHP language: PHP References Explained

A very nice technical explanation by @NikiC of the internal logic of PHP foreach loops:
How does PHP 'foreach' actually work?

If you want more than one style this is the correct full answer. This is div with class and style:

<div className="class-example" style={{width: '300px', height: '150px'}}></div>

If you are looking for a real simple way to log, you can use this one liner. If the file doesn't exist, it's created.

System.IO.File.AppendAllText(@"c:\log.txt", "mymsg\n");

@Patrick I would improve your solution a bit

@Override
public Object deserialize(JsonParser jp, DeserializationContext ctxt)
        throws IOException, JsonProcessingException {        
    ObjectNode objectNode = jp.readValueAsTree();
    JsonNode wrapped = objectNode.get(wrapperKey);
    JsonParser parser = node.traverse();
    parser.setCodec(jp.getCodec());
    Vendor mapped = parser.readValueAs(Vendor.class);
    return mapped;
}

It works faster :)

This is what I use and it works in Linux environments. I don't think this would work on a Windows machine...

//define canonicalized absolute pathname for the script
if(substr($_SERVER['SCRIPT_NAME'],0,1) == DIRECTORY_SEPARATOR) {
    //does the script name start with the directory separator?
    //if so, the path is defined from root; may have symbolic references so still use realpath()
    $script = realpath($_SERVER['SCRIPT_NAME']);
} else {
    //otherwise prefix script name with the current working directory
    //and use realpath() to resolve symbolic references
    $script = realpath(getcwd() . DIRECTORY_SEPARATOR . $_SERVER['SCRIPT_NAME']);
}

GC efficiency relies on a number of heuristics. For instance, a common heuristic is that write accesses to objects usually occur on objects which were created not long ago. Another is that many objects are very short-lived (some objects will be used for a long time, but many will be discarded a few microseconds after their creation).

Calling System.gc() is like kicking the GC. It means: "all those carefully tuned parameters, those smart organizations, all the effort you just put into allocating and managing the objects such that things go smoothly, well, just drop the whole lot, and start from scratch". It may improve performance, but most of the time it just degrades performance.

To use System.gc() reliably(*) you need to know how the GC operates in all its fine details. Such details tend to change quite a bit if you use a JVM from another vendor, or the next version from the same vendor, or the same JVM but with slightly different command-line options. So it is rarely a good idea, unless you want to address a specific issue in which you control all those parameters. Hence the notion of "bad practice": that's not forbidden, the method exists, but it rarely pays off.

(*) I am talking about efficiency here. System.gc() will never break a correct Java program. It will neither conjure extra memory that the JVM could not have obtained otherwise: before throwing an OutOfMemoryError, the JVM does the job of System.gc(), even if as a last resort.

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

That is ill-formatted. You have one JSON object per line, but they are not contained in a larger data structure (ie an array). You'll either need to reformat it so that it begins with [ and ends with ] with a comma at the end of each line, or parse it line by line as separate dictionaries.

You don't want a string, you really want a JS map of key value pairs. E.g., change:

 data: myDataVar.toString(),

with:

var myKeyVals = { A1984 : 1, A9873 : 5, A1674 : 2, A8724 : 1, A3574 : 3, A1165 : 5 }



var saveData = $.ajax({
      type: 'POST',
      url: "someaction.do?action=saveData",
      data: myKeyVals,
      dataType: "text",
      success: function(resultData) { alert("Save Complete") }
});
saveData.error(function() { alert("Something went wrong"); });

jQuery understands key value pairs like that, it does NOT understand a big string. It passes it simply as a string.

UPDATE: Code fixed.

To revert modified files:

sudo svn revert
svn status|grep "^ *M" | sed -e 's/^ *M *//'

The error means, that Angular doesn't know what to do when you put a formControl on a div. To fix this, you have two options.

1. You put the formControlName on an element, that is supported by Angular out of the box. Those are: input, textarea and select.
2. You implement the ControlValueAccessor interface. By doing so, you're telling Angular "how to access the value of your control" (hence the name). Or in simple terms: What to do, when you put a formControlName on an element, that doesn't naturally have a value associated with it.

Now, implementing the ControlValueAccessor interface can be a bit daunting at first. Especially because there isn't much good documentation of this out there and you need to add a lot of boilerplate to your code. So let me try to break this down in some simple-to-follow steps.

Move your form control into its own component

In order to implement the ControlValueAccessor, you need to create a new component (or directive). Move the code related to your form control there. Like this it will also be easily reusable. Having a control already inside a component might be the reason in the first place, why you need to implement the ControlValueAccessor interface, because otherwise you will not be able to use your custom component together with Angular forms.

Add the boilerplate to your code

Implementing the ControlValueAccessor interface is quite verbose, here's the boilerplate that comes with it:

import {Component, OnInit, forwardRef} from '@angular/core';
import {ControlValueAccessor, FormControl, NG_VALUE_ACCESSOR} from '@angular/forms';


@Component({
  selector: 'app-custom-input',
  templateUrl: './custom-input.component.html',
  styleUrls: ['./custom-input.component.scss'],

  // a) copy paste this providers property (adjust the component name in the forward ref)
  providers: [
    {
      provide: NG_VALUE_ACCESSOR,
      useExisting: forwardRef(() => CustomInputComponent),
      multi: true
    }
  ]
})
// b) Add "implements ControlValueAccessor"
export class CustomInputComponent implements ControlValueAccessor {

  // c) copy paste this code
  onChange: any = () => {}
  onTouch: any = () => {}
  registerOnChange(fn: any): void {
    this.onChange = fn;
  }
  registerOnTouched(fn: any): void {
    this.onTouch = fn;
  }

  // d) copy paste this code
  writeValue(input: string) {
    // TODO
  }

So what are the individual parts doing?

• a) Lets Angular know during runtime that you implemented the ControlValueAccessor interface
• b) Makes sure you're implementing the ControlValueAccessor interface
• c) This is probably the most confusing part. Basically what you're doing is, you give Angular the means to override your class properties/methods onChange and onTouch with it's own implementation during runtime, such that you can then call those functions. So this point is important to understand: You don't need to implement onChange and onTouch yourself (other than the initial empty implementation). The only thing your doing with (c) is to let Angular attach it's own functions to your class. Why? So you can then call the onChange and onTouch methods provided by Angular at the appropriate time. We'll see how this works down below.
• d) We'll also see how the writeValue method works in the next section, when we implement it. I've put it here, so all required properties on ControlValueAccessor are implemented and your code still compiles.

Implement writeValue

What writeValue does, is to do something inside your custom component, when the form control is changed on the outside. So for example, if you have named your custom form control component app-custom-input and you'd be using it in the parent component like this:

<form [formGroup]="form">
  <app-custom-input formControlName="myFormControl"></app-custom-input>
</form>

then writeValue gets triggered whenever the parent component somehow changes the value of myFormControl. This could be for example during the initialization of the form (this.form = this.formBuilder.group({myFormControl: ""});) or on a form reset this.form.reset();.

What you'll typically want to do if the value of the form control changes on the outside, is to write it to a local variable which represents the form control value. For example, if your CustomInputComponent revolves around a text based form control, it could look like this:

writeValue(input: string) {
  this.input = input;
}

and in the html of CustomInputComponent:

<input type="text"
       [ngModel]="input">

You could also write it directly to the input element as described in the Angular docs.

Now you have handled what happens inside of your component when something changes outside. Now let's look at the other direction. How do you inform the outside world when something changes inside of your component?

Calling onChange

The next step is to inform the parent component about changes inside of your CustomInputComponent. This is where the onChange and onTouch functions from (c) from above come into play. By calling those functions you can inform the outside about changes inside your component. In order to propagate changes of the value to the outside, you need to call onChange with the new value as the argument. For example, if the user types something in the input field in your custom component, you call onChange with the updated value:

<input type="text"
       [ngModel]="input"
       (ngModelChange)="onChange($event)">

If you check the implementation (c) from above again, you'll see what's happening: Angular bound it's own implementation to the onChange class property. That implementation expects one argument, which is the updated control value. What you're doing now is you're calling that method and thus letting Angular know about the change. Angular will now go ahead and change the form value on the outside. This is the key part in all this. You told Angular when it should update the form control and with what value by calling onChange. You've given it the means to "access the control value".

By the way: The name onChange is chosen by me. You could choose anything here, for example propagateChange or similar. However you name it though, it will be the same function that takes one argument, that is provided by Angular and that is bound to your class by the registerOnChange method during runtime.

Calling onTouch

Since form controls can be "touched", you should also give Angular the means to understand when your custom form control is touched. You can do it, you guessed it, by calling the onTouch function. So for our example here, if you want to stay compliant with how Angular is doing it for the out-of-the-box form controls, you should call onTouch when the input field is blurred:

<input type="text"
       [(ngModel)]="input"
       (ngModelChange)="onChange($event)"
       (blur)="onTouch()">

Again, onTouch is a name chosen by me, but what it's actual function is provided by Angular and it takes zero arguments. Which makes sense, since you're just letting Angular know, that the form control has been touched.

Putting it all together

So how does that look when it comes all together? It should look like this:

// custom-input.component.ts
import {Component, OnInit, forwardRef} from '@angular/core';
import {ControlValueAccessor, FormControl, NG_VALUE_ACCESSOR} from '@angular/forms';


@Component({
  selector: 'app-custom-input',
  templateUrl: './custom-input.component.html',
  styleUrls: ['./custom-input.component.scss'],

  // Step 1: copy paste this providers property
  providers: [
    {
      provide: NG_VALUE_ACCESSOR,
      useExisting: forwardRef(() => CustomInputComponent),
      multi: true
    }
  ]
})
// Step 2: Add "implements ControlValueAccessor"
export class CustomInputComponent implements ControlValueAccessor {

  // Step 3: Copy paste this stuff here
  onChange: any = () => {}
  onTouch: any = () => {}
  registerOnChange(fn: any): void {
    this.onChange = fn;
  }
  registerOnTouched(fn: any): void {
    this.onTouch = fn;
  }

  // Step 4: Define what should happen in this component, if something changes outside
  input: string;
  writeValue(input: string) {
    this.input = input;
  }

  // Step 5: Handle what should happen on the outside, if something changes on the inside
  // in this simple case, we've handled all of that in the .html
  // a) we've bound to the local variable with ngModel
  // b) we emit to the ouside by calling onChange on ngModelChange

}

// custom-input.component.html
<input type="text"
       [(ngModel)]="input"
       (ngModelChange)="onChange($event)"
       (blur)="onTouch()">

// parent.component.html
<app-custom-input [formControl]="inputTwo"></app-custom-input>

// OR

<form [formGroup]="form" >
  <app-custom-input formControlName="myFormControl"></app-custom-input>
</form>

Nested Forms

Note that Control Value Accessors are NOT the right tool for nested form groups. For nested form groups you can simply use an @Input() subform instead. Control Value Accessors are meant to wrap controls, not groups! See this example how to use an input for a nested form: https://stackblitz.com/edit/angular-nested-forms-input-2

Dont work for me, need to put scope in plural

validates_uniqueness_of :teacher_id, :scopes => [:semester_id, :class_id]

In all of the above, the EditText still needs the focusable="false" attribute in the xml in order to prevent the keyboard from popping up.

public static String[] split(String input, int length) throws IllegalArgumentException {

    if(length == 0 || input == null)
        return new String[0];

    int lengthD = length * 2;

    int size = input.length();
    if(size == 0)
        return new String[0];

    int rep = (int) Math.ceil(size * 1d / length);

    ByteArrayInputStream stream = new ByteArrayInputStream(input.getBytes(StandardCharsets.UTF_16LE));

    String[] out = new String[rep];
    byte[]  buf = new byte[lengthD];

    int d = 0;
    for (int i = 0; i < rep; i++) {

        try {
            d = stream.read(buf);
        } catch (IOException e) {
            e.printStackTrace();
        }

        if(d != lengthD)
        {
            out[i] = new String(buf,0,d, StandardCharsets.UTF_16LE);
            continue;
        }

        out[i] = new String(buf, StandardCharsets.UTF_16LE);
    }
    return out;
}

I would use null to show that there is no value for that particular key. For example, use null to represent that "number of devices in your household connects to internet" is unknown.

On the other hand, use {} if that particular key is not applicable. For example, you should not show a count, even if null, to the question "number of cars that has active internet connection" is asked to someone who does not own any cars.

I would avoid defaulting any value unless that default makes sense. While you may decide to use null to represent no value, certainly never use "null" to do so.

This also plays .mp3 files.

Adding debugger; on top at my script worked for me.

Typically, you'd use the NODE_ENV variable to take special actions when you develop, test and debug your code. For example to produce detailed logging and debug output which you don't want in production. Express itself behaves differently depending on whether NODE_ENV is set to production or not. You can see this if you put these lines in an Express app, and then make a HTTP GET request to /error:

app.get('/error', function(req, res) {
  if ('production' !== app.get('env')) {
    console.log("Forcing an error!");
  }
  throw new Error('TestError');
});

app.use(function (req, res, next) {
  res.status(501).send("Error!")
})

Note that the latter app.use() must be last, after all other method handlers!

If you set NODE_ENV to production before you start your server, and then send a GET /error request to it, you should not see the text Forcing an error! in the console, and the response should not contain a stack trace in the HTML body (which origins from Express). If, instead, you set NODE_ENV to something else before starting your server, the opposite should happen.

In Linux, set the environment variable NODE_ENV like this:

export NODE_ENV='value'

Hi Guys you cant convert directly string to bigdecimal

you need to first convert it into long after that u will convert big decimal

String currency = "135.69"; 
Long rate1=Long.valueOf((currency ));            
System.out.println(BigDecimal.valueOf(rate1));

The VARCHAR(MAX) type is a replacement for TEXT. The basic difference is that a TEXT type will always store the data in a blob whereas the VARCHAR(MAX) type will attempt to store the data directly in the row unless it exceeds the 8k limitation and at that point it stores it in a blob.

Using the LIKE statement is identical between the two datatypes. The additional functionality VARCHAR(MAX) gives you is that it is also can be used with = and GROUP BY as any other VARCHAR column can be. However, if you do have a lot of data you will have a huge performance issue using these methods.

In regard to if you should use LIKE to search, or if you should use Full Text Indexing and CONTAINS. This question is the same regardless of VARCHAR(MAX) or TEXT.

If you are searching large amounts of text and performance is key then you should use a Full Text Index.

LIKE is simpler to implement and is often suitable for small amounts of data, but it has extremely poor performance with large data due to its inability to use an index.

Try adding this to your where clause:

dateadd(day, -30, getdate())

Posting another script solution DateX (author) for anyone interested

DateX does NOT wrap the original Date object, but instead offers an identical interface with additional methods to format, localise, parse, diff and validate dates easily. So one can just do new DateX(..) instead of new Date(..) or use the lib as date utilities or even as wrapper or replacement around Date class.

The date format used is identical to php date format.

c-like format is also supported (although not fully)

for the example posted (YYYY/mm/dd hh:m:sec) the format to use would be Y/m/d H:i:s eg

var formatted_date = new DateX().format('Y/m/d H:i:s');

or

var formatted_now_date_gmt = new DateX(DateX.UTC()).format('Y/m/d H:i:s');

ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NOT NULL

This expression

SELECT (((DATEPART(DW, @my_date_var) - 1 ) + @@DATEFIRST ) % 7)

will always return a number between 0 and 6 where

0 -> Sunday
1 -> Monday
2 -> Tuesday
3 -> Wednesday
4 -> Thursday
5 -> Friday
6 -> Saturday

Independently from @@DATEFIRST

So a weekend day is tested like this

SELECT (CASE
           WHEN (((DATEPART(DW, @my_date_var) - 1 ) + @@DATEFIRST ) % 7) IN (0,6)
           THEN 1
           ELSE 0
       END) AS is_weekend_day

you can also use gcc -v command that works like gcc --version and if you would like to now where gcc is you can use whereis gcc command

I hope it'll be usefull

Or you could use

show tables where Tables_in_{insert_db_name}='tablename';

Check out the boost NumericConversion library. It will allow to explicitly control how you want to deal with issues like overflow handling and truncation.

One easy way to select random items is to shuffle then slice.

import random
a = [1,2,3,4,5,6,7,8,9]
random.shuffle(a)
print a[:4] # prints 4 random variables

Sorry, brief moment of synapse failure. Here's the real answer.

require 'date'

Time.at(seconds_since_epoch_integer).to_datetime

Brief example (this takes into account the current system timezone):

$ date +%s
1318996912

$ irb

ruby-1.9.2-p180 :001 > require 'date'
 => true 

ruby-1.9.2-p180 :002 > Time.at(1318996912).to_datetime
 => #<DateTime: 2011-10-18T23:01:52-05:00 (13261609807/5400,-5/24,2299161)> 

Further update (for UTC):

ruby-1.9.2-p180 :003 > Time.at(1318996912).utc.to_datetime
 => #<DateTime: 2011-10-19T04:01:52+00:00 (13261609807/5400,0/1,2299161)>

Recent Update: I benchmarked the top solutions in this thread while working on a HA service a week or two ago, and was surprised to find that Time.at(..) outperforms DateTime.strptime(..) (update: added more benchmarks).

The only case I could imagine is, that you run this on a webkit browser like Chrome or Safari and your return value in responseText, contains a string value.

In that constelation, the value cannot be displayed (it would get blank)

Example: http://jsfiddle.net/BmhNL/2/

My point here is, that I expect a wrong/double encoded string value. Webkit browsers are more strict on the type = number. If there is "only" a white-space issue, you can try to implicitly call the Number() constructor, like

document.getElementById("points").value = +request.responseText;

Very simple you have to just put
\n where ever you want to break line in your string resource.

For example

String s = my string resource have \n line break here;

How about exporting the variable, but only inside the subshell?:

(export FOO=bar && somecommand someargs | somecommand2)

Keith has a point, to unconditionally execute the commands, do this:

(export FOO=bar; somecommand someargs | somecommand2)

One alternative for IE7+ and other browsers may be to use :first-child instead, and invert your styles.

For example, if you're setting the margin on each li:

ul li {
  margin-bottom: 1em;
}
ul li:last-child {
  margin-bottom: 0;
}

You could replace it with this:

ul li {
  margin-top: 1em;
}
ul li:first-child {
  margin-top: 0;
}

This will work well for some other cases like borders.

According to sitepoint, :first-child buggy, but only to the extent that it will select some root elements (the doctype or html), and may not change styles if other elements are inserted.

Return false from the anonymous function:

$(xml).find("strengths").each(function() {
  // Code
  // To escape from this block based on a condition:
  if (something) return false;
});

From the documentation of the each method:

Returning 'false' from within the each function completely stops the loop through all of the elements (this is like using a 'break' with a normal loop). Returning 'true' from within the loop skips to the next iteration (this is like using a 'continue' with a normal loop).

Yeah, by using $(this), you enabled jQuery functionality for the object. By just using this, it only has generic Javascript functionality.

I'd strongly recommend to keep working with swap files (in case Vim crashes).

You can set the directory where the swap files are stored, so they don't clutter your normal directories:

set swapfile
set dir=~/tmp

:help swap-file

no need for the padding or the corners.

I believe you have to reference bootstrap.js before bootstrap-datepicker.js

After stumbling around, this worked for me:

df = df.astype(object).where(pd.notnull(df),None)

Password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

This one works for me.
But you have to look at Octavian Damiean's comment, he's right.

I usually pass the RowIndex via CommandArgument and use it to retrieve the DataKey value I want.

On the Button:

CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>'

On the Server Event

int rowIndex = int.Parse(e.CommandArgument.ToString());
string val = (string)this.grid.DataKeys[rowIndex]["myKey"];

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.

Strings in C# already have a char indexer

string test = "this is a test";
Console.WriteLine(test[0]);

And...

if(test[0] == 't')
  Console.WriteLine("The first letter is 't'");

This works too...

Console.WriteLine("this is a test"[0]);

And this...

foreach (char c in "this is a test")
  Console.WriteLine(c);

EDIT:

I noticed the question was updated with regards to char[] arrays. If you must have a string[] array, here's how you split a string at each character in c#:

string[] test = Regex.Split("this is a test", string.Empty);

foreach (string s in test)
{
  Console.WriteLine(s);
}

What I do is catch this exception, together with another possible exceptions. Hope this help someone.

 catch (ThreadAbortException ex1)
 {
    writeToLog(ex1.Message);
 }
 catch(Exception ex)
 {
     writeToLog(ex.Message);
 }

I think the LINQ expression may be best:

   const string MyKey = "myKey"

   if (ConfigurationManager.AppSettings.AllKeys.Any(key => key == MyKey))
          {
              // Key exists
          }

What you can do is use a pixmap as an icon and then put this icon onto the button.

To make sure the size of the button will be correct, you have to reisze the icon according to the pixmap size.

Something like this should work :

QPixmap pixmap("image_path");
QIcon ButtonIcon(pixmap);
button->setIcon(ButtonIcon);
button->setIconSize(pixmap.rect().size());

On CentOS 7, the following works:

yum install php-soap

This will automatically create a soap.ini under /etc/php.d.

The extension itself for me lives in /usr/lib64/php/modules. You can confirm your extension directory by doing:

php -i | grep extension_dir

Once this has been installed, you can simply restart Apache using the new service manager like so:

systemctl restart httpd

Thanks to Matt Browne for the info about /etc/php.d.

In Excel 2010, You have the countifS function.

I was having issues if I was trying to count the number of cells in a range that have a non0 value.

e.g. If you had a worksheet that in the range A1:A10 had values 1, 0, 2, 3, 0 and you wanted the answer 3.

The normal function =COUNTIF(A1:A10,"<>0") would give you 8 as it is counting the blank cells as 0s.

My solution to this is to use the COUNTIFS function with the same range but multiple criteria e.g.

=COUNTIFS(A1:A10,"<>0",A1:A10,"<>")

This effectively checks if the range is non 0 and is non blank.

You can also edit the preferences file by hand to set the Array Fetch Size to any value.

Mine is found at C:\Users\<user>\AppData\Roaming\SQL Developer\system4.0.2.15.21\o.sqldeveloper.12.2.0.15.21\product-preferences.xml on Win 7 (x64).

The value is on line 372 for me and reads <value n="ARRAYFETCHSIZE" v="200"/>

I have changed it to 2000 and it works for me.

I had to restart SQL Developer.

This is based off of Erik's answer from earlier, but I've found it easiest to read in the .csv file using pandas and then create a new instance of the class for every row in the in data frame.

This example is updated using iloc as pandas no longer uses ix in the most recent version. I don't know about Erik's situation but you need to create the list outside of the for loop otherwise it will not append to your array but simply overwrite it.

import pandas as pd
df = pd.read_csv('path_to_file', sep='delimiter')
products = []
for i in range(len(df)):
    products.append(
        Product(
        name=df.iloc[i][0]
        description=df.iloc[i][1]
        price=df.iloc[i][2]
        )
    )
Product.objects.bulk_create(products)

This is just breaking the DataFrame into an array of rows and then selecting each column out of that array off the zero index. (i.e. name is the first column, description the second, etc.)

Hope that helps.

use agent detector and then with your web language create program to create css

for example in python

csscreator()
    useragent = detector()
    if useragent == "Firefox":
         css = "your css"
    ...
    return css

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

// mutiple image retrieve

 File folPath = new File(getIntent().getStringExtra("folder_path"));
 File[] imagep = folPath.listFiles();

 for (int i = 0; i < imagep.length ; i++) {
     imageModelList.add(new ImageModel(imagep[i].getAbsolutePath(), Uri.parse(imagep[i].getAbsolutePath())));
 }
 imagesAdapter.notifyDataSetChanged();

I figured this might come in handy for others as well :

find:

• ([A-Z])(.*)

replace:

• \L$1$2 --> will convert all letters in $1 and $2 to lowercase
  BUT
• \l$1$2 --> will only convert the first letter of $1 to lowercase and leave everything else as is

The same goes for uppercase with \U and \u

My answer would be "be careful". A lot of jQuery table-sorting add-ons only sort what you pass to the browser. In many cases, you have to keep in mind that tables are dynamic sets of data, and could potentially contain zillions of lines of data.

You do mention that you only have 4 columns, but much more importantly, you don't mention how many rows we're talking about here.

If you pass 5000 lines to the browser from the database, knowing that the actual database-table contains 100,000 rows, my question is: what's the point in making the table sortable? In order to do a proper sort, you'd have to send the query back to the database, and let the database (a tool actually designed to sort data) do the sorting for you.

In direct answer to your question though, the best sorting add-on I've come across is Ingrid. There are many reasons that I don't like this add-on ("unnecessary bells and whistles..." as you call it), but one of it's best features in terms of sort, is that it uses ajax, and doesn't assume that you've already passed it all the data before it does its sort.

I recognise that this answer is probably overkill (and over 2 years late) for your requirements, but I do get annoyed when developers in my field overlook this point. So I hope someone else picks up on it.

I feel better now.

In oracle an empty varchar2 and null are treated the same, and your observations show that.

when you write:

select * from table where a = '';

its the same as writing

select * from table where a = null;

and not a is null

which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)

Bootstrap 4.0

Be aware of all migration changes from Bootstrap 3 to 4. On the table you now need to enable flex box by adding the class d-flex, and drop the xs to allow bootstrap to automatically detect the viewport.

<div class="container-fluid">
    <table id="productSizes" class="table">
        <thead>
            <tr class="d-flex">
                <th class="col-1">Size</th>
                <th class="col-3">Bust</th>
                <th class="col-3">Waist</th>
                <th class="col-5">Hips</th>
            </tr>
        </thead>
        <tbody>
            <tr class="d-flex">
                <td class="col-1">6</td>
                <td class="col-3">79 - 81</td>
                <td class="col-3">61 - 63</td>
                <td class="col-5">89 - 91</td>
            </tr>
            <tr class="d-flex">
                <td class="col-1">8</td>
                <td class="col-3">84 - 86</td>
                <td class="col-3">66 - 68</td>
                <td class="col-5">94 - 96</td>
            </tr>
        </tbody>
    </table>

Bootstrap 3.2

Table column width use the same layout as grids do; using col-[viewport]-[size]. Remember the column sizes should total 12; 1 + 3 + 3 + 5 = 12 in this example.

        <thead>
            <tr>
                <th class="col-xs-1">Size</th>
                <th class="col-xs-3">Bust</th>
                <th class="col-xs-3">Waist</th>
                <th class="col-xs-5">Hips</th>
            </tr>
        </thead>

Remember to set the <th> elements rather than the <td> elements so it sets the whole column. Here is a working BOOTPLY.

Thanks to @Dan for reminding me to always work mobile view (col-xs-*) first.

For Windows users looking for solution of same problem. I just repleced

LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"

in my /conf/extra/http?-xampp.conf

in your Project perspective, look for Application --> build.gradle and edit this lines

android { compileSdkVersion "android-N" buildToolsVersion "24.0.0 rc1"

like this:

android { compileSdkVersion 24 buildToolsVersion "23.0.3"

Was also struggling with this error and based on the topic here and this answer was able to figure out snippet to copy/paste without the need to figure out what has to be imported (excellent for C# beginners), code below:

try
{
  context.SaveChanges();
}
catch (System.Data.Entity.Validation.DbEntityValidationException ex)
{
  foreach (var entityValidationErrors in ex.EntityValidationErrors)
  {
    foreach (var validationError in entityValidationErrors.ValidationErrors)
    {
      System.Diagnostics.Debug.WriteLine("Property: " + validationError.PropertyName + " Error: " + validationError.ErrorMessage);
    }
  }
}

Its always good to have these additional properties besides the

background-image:url('path') no-repeat 0 0;

1. set dimension to the element

   width:x; height:y;

2. background-size:100%

   • This property helps to fit the image to the above dimension that you define for an element.

If you don't want any loops, you'll have to write it out:

#include <stdio.h>
#include <stdbool.h>

int main(void)
{
    int num = 7;

    #if 0
        bool arr[4] = { (num&1) ?true: false, (num&2) ?true: false, (num&4) ?true: false, (num&8) ?true: false };
    #else
        #define BTB(v,i) ((v) & (1u << (i))) ? true : false
        bool arr[4] = { BTB(num,0), BTB(num,1), BTB(num,2), BTB(num,3)};
        #undef BTB
    #endif

    printf("%d %d %d %d\n", arr[3], arr[2], arr[1], arr[0]);

    return 0;
}

As demonstrated here, this also works in an initializer.

Please select the same in the outer select. You can't access the alias name in the same query.

SELECT *, (CASE
        WHEN articleNumber < 2 THEN 'Ama'
        WHEN articleNumber < 5 THEN 'SemiAma' 
        WHEN articleNumber < 7 THEN 'Good'  
        WHEN articleNumber < 9 THEN 'Better' 
        WHEN articleNumber < 12 THEN 'Best'
        ELSE 'Outstanding'
        END) AS ranking 
FROM(
    SELECT registrationDate, (SELECT COUNT(*) FROM Articles WHERE Articles.userId = Users.userId) as articleNumber, 
    hobbies, etc...
    FROM USERS
)x

None of these answers really work. As others noted the Cors package will only use the Access-Control-Allow-Origin header if the request had an Origin header. But you can't generally just add an Origin header to the request because browsers may try to regulate that too.

If you want a quick and dirty way to allow cross site requests to a web api, it's really a lot easier to just write a custom filter attribute:

public class AllowCors : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        if (actionExecutedContext == null)
        {
            throw new ArgumentNullException("actionExecutedContext");
        }
        else
        {
            actionExecutedContext.Response.Headers.Remove("Access-Control-Allow-Origin");
            actionExecutedContext.Response.Headers.Add("Access-Control-Allow-Origin", "*");
        }
        base.OnActionExecuted(actionExecutedContext);
    }
}

Then just use it on your Controller action:

[AllowCors]
public IHttpActionResult Get()
{
    return Ok("value");
}

I won't vouch for the security of this in general, but it's probably a lot safer than setting the headers in the web.config since this way you can apply them only as specifically as you need them.

And of course it is simple to modify the above to allow only certain origins, methods etc.

Here's my attempt, it doesn't follow your specs exactly though. Not fully tested, so be cautious.

what i did to restore the scroll position after refreshing the RecyclerView on button clicked:

if (linearLayoutManager != null) {

    index = linearLayoutManager.findFirstVisibleItemPosition();
    View v = linearLayoutManager.getChildAt(0);
    top = (v == null) ? 0 : (v.getTop() - linearLayoutManager.getPaddingTop());
    Log.d("TAG", "visible position " + " " + index);
}

else{
    index = 0;
}

linearLayoutManager = new LinearLayoutManager(getApplicationContext());
linearLayoutManager.scrollToPositionWithOffset(index, top);

getting the offset of the first visible item from the top before creating the linearLayoutManager object and after instantiating it the scrollToPositionWithOffset of the LinearLayoutManager object was called.

% notation is called a format specifier. For example, %d tells printf() to print an integer. %s to print a string (char *) etc. You should really look it up here: http://google.com/search?q=printf+format+specifiers

No, commas are not used for string concatenation. Commas are for separating arguments passed to a function.

Obviously I'm a little out of season on this question but for the benefit of the next sufferer: I just had this problem and in my case (in contrast to OP who tried the same without success) the fix was to revise php.ini, changing

date.timezone = America/New York

to

date.timezone = America/New_York

That is adding the underscore.

Here's another method that's unorthodox, but works*.

I recently found myself in a situation where I'd checked in breaking code, knowing that I couldn't update our production code to it until all the integration work had taken place (in retrospect this was a bad decision, but we didn't expect to get stalled out, but other projects took precedence). That was several months ago, and the integration has been stalled for that entire time. Along comes a requirement to change the base code and get it into production last week without the breaking change.

Here's what we did:

After verifying that the new requirement doesn't break anything when using the revision before my check in, I made a copy of the working directory containing the new code. Then I deleted everything in the working directory and checked out the revision I wanted to it. Then I deleted all the files I'd just checked out, and copied in the files from the working copy. Then I committed that change, effectively wiping out the breaking change from the repository and getting the production code in place as the head revision. We still have the breaking change available, but it's no longer in the head revision so we can move forward to production.

*I don't recommend this method, but if you find yourself in a similar situation, it's a way out that's not too painful.

In a nutshell, ZooKeeper helps you build distributed applications.

How it works

You may describe ZooKeeper as a replicated synchronization service with eventual consistency. It is robust, since the persisted data is distributed between multiple nodes (this set of nodes is called an "ensemble") and one client connects to any of them (i.e., a specific "server"), migrating if one node fails; as long as a strict majority of nodes are working, the ensemble of ZooKeeper nodes is alive. In particular, a master node is dynamically chosen by consensus within the ensemble; if the master node fails, the role of master migrates to another node.

How writes are handled

The master is the authority for writes: in this way writes can be guaranteed to be persisted in-order, i.e., writes are linear. Each time a client writes to the ensemble, a majority of nodes persist the information: these nodes include the server for the client, and obviously the master. This means that each write makes the server up-to-date with the master. It also means, however, that you cannot have concurrent writes.

The guarantee of linear writes is the reason for the fact that ZooKeeper does not perform well for write-dominant workloads. In particular, it should not be used for interchange of large data, such as media. As long as your communication involves shared data, ZooKeeper helps you. When data could be written concurrently, ZooKeeper actually gets in the way, because it imposes a strict ordering of operations even if not strictly necessary from the perspective of the writers. Its ideal use is for coordination, where messages are exchanged between the clients.

How reads are handled

This is where ZooKeeper excels: reads are concurrent since they are served by the specific server that the client connects to. However, this is also the reason for the eventual consistency: the "view" of a client may be outdated, since the master updates the corresponding server with a bounded but undefined delay.

In detail

The replicated database of ZooKeeper comprises a tree of znodes, which are entities roughly representing file system nodes (think of them as directories). Each znode may be enriched by a byte array, which stores data. Also, each znode may have other znodes under it, practically forming an internal directory system.

Sequential znodes

Interestingly, the name of a znode can be sequential, meaning that the name the client provides when creating the znode is only a prefix: the full name is also given by a sequential number chosen by the ensemble. This is useful, for example, for synchronization purposes: if multiple clients want to get a lock on a resource, they can each concurrently create a sequential znode on a location: whoever gets the lowest number is entitled to the lock.

Ephemeral znodes

Also, a znode may be ephemeral: this means that it is destroyed as soon as the client that created it disconnects. This is mainly useful in order to know when a client fails, which may be relevant when the client itself has responsibilities that should be taken by a new client. Taking the example of the lock, as soon as the client having the lock disconnects, the other clients can check whether they are entitled to the lock.

Watches

The example related to client disconnection may be problematic if we needed to periodically poll the state of znodes. Fortunately, ZooKeeper offers an event system where a watch can be set on a znode. These watches may be set to trigger an event if the znode is specifically changed or removed or new children are created under it. This is clearly useful in combination with the sequential and ephemeral options for znodes.

Where and how to use it

A canonical example of Zookeeper usage is distributed-memory computation, where some data is shared between client nodes and must be accessed/updated in a very careful way to account for synchronization.

ZooKeeper offers the library to construct your synchronization primitives, while the ability to run a distributed server avoids the single-point-of-failure issue you have when using a centralized (broker-like) message repository.

ZooKeeper is feature-light, meaning that mechanisms such as leader election, locks, barriers, etc. are not already present, but can be written above the ZooKeeper primitives. If the C/Java API is too unwieldy for your purposes, you should rely on libraries built on ZooKeeper such as cages and especially curator.

Where to read more

Official documentation apart, which is pretty good, I suggest to read Chapter 14 of Hadoop: The Definitive Guide which has ~35 pages explaining essentially what ZooKeeper does, followed by an example of a configuration service.

This is most likely not an answer to the issue itself but this question pops up as first result when searching for Sql declare scalar variable hence i share a possible solution to this error.

In my case this error was caused by the use of ; after a SQL statement. Just remove it and the error will be gone.

I guess the cause is the same as @IronSean already posted in an comment above:

it's worth noting that using GO (or in this case ;) causes a new branch where declared variables aren't visible past the statement.

For example:

DECLARE @id int
SET @id = 78

SELECT * FROM MyTable WHERE Id = @var; <-- remove this character to avoid the error message
SELECT * FROM AnotherTable WHERE MyTableId = @var

There is this extensions that adds an event listener to attribute changes.

Bind attrchange handler function to selected elements

$(selector).attrchange({
    trackValues: true, /* Default to false, if set to true the event object is 
                updated with old and new value.*/
    callback: function (event) { 
        //event               - event object
        //event.attributeName - Name of the attribute modified
        //event.oldValue      - Previous value of the modified attribute
        //event.newValue      - New value of the modified attribute
        //Triggered when the selected elements attribute is added/updated/removed
    }        
});

r+ is used for reading, and writing mode. b is for binary. r+b mode is open the binary file in read or write mode.

@Kumar

"W7 prompts everytime to run this program "devenv.exe" , anyway to get rid of that ?"

Yes. You can prevent Windows from prompting you by going to Control Panel/User Accounts/Change User Account Control settings and move the slider down.

Try this code.

var startTime = "05:01:20";
var endTime = "09:00:00";
var regExp = /(\d{1,2})\:(\d{1,2})\:(\d{1,2})/;
if(parseInt(endTime .replace(regExp, "$1$2$3")) > parseInt(startTime .replace(regExp, "$1$2$3"))){
alert("End time is greater");
}

Yes. But place your "test" after the comma if you want the column...

> A <- matrix(sample(1:12,12,T),ncol=4)

> rownames(A) <- letters[1:3]

> colnames(A) <- letters[11:14]
> A[,"l"]
 a  b  c

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

Use In instead of =

 select * from dbo.books
 where isbn in (select isbn from dbo.lending 
                where act between @fdate and @tdate
                and stat ='close'
               )

or you can use Exists

SELECT t1.*,t2.*
FROM  books   t1 
WHERE  EXISTS ( SELECT * FROM dbo.lending t2 WHERE t1.isbn = t2.isbn and
                t2.act between @fdate and @tdate and t2.stat ='close' )

simple is the best and works in every version.

if a>10: 
    value="b"
else: 
    value="c"

String.Format also works in Razor:

String.Format("{0} - {1}", Model.address, Model.city)

You could google on "tuple unpacking". This can be used in various places in Python. The simplest is in assignment

>>> x = (1,2)
>>> a, b = x
>>> a
1
>>> b
2

In a for loop it works similarly. If each element of the iterable is a tuple, then you can specify two variables and each element in the loop will be unpacked to the two.

>>> x = [(1,2), (3,4), (5,6)]
>>> for item in x:
...     print "A tuple", item
A tuple (1, 2)
A tuple (3, 4)
A tuple (5, 6)
>>> for a, b in x:
...     print "First", a, "then", b
First 1 then 2
First 3 then 4
First 5 then 6

The enumerate function creates an iterable of tuples, so it can be used this way.

Hope it helps.

Elasticsearch settings are in $ES_HOME/config/elasticsearch.yml. There, if the cluster.name setting is commented out, it means ES would take just about any cluster name. So, in your code, the cluster.name as "elastictest" might be the problem. Try this:

Client client = new TransportClient()
                .addTransportAddress(new InetSocketTransportAddress(
                        "143.79.236.xxx",
                        9300));

You could create a table somewhere on a calculation spreadsheet which performs this operation for each pair of cells, and use auto-fill to fill it up.

Aggregate the results from that table into a results cell.

The 200 so cells which reference the results could then reference the cell that holds the aggregation results. In the newest versions of excel you can name the result cell and reference it that way, for ease of reading.

The best way is to do a mongodump then mongorestore. You can select the collection via:

mongodump -d some_database -c some_collection

[Optionally, zip the dump (zip some_database.zip some_database/* -r) and scp it elsewhere]

Then restore it:

mongorestore -d some_other_db -c some_or_other_collection dump/some_collection.bson

Existing data in some_or_other_collection will be preserved. That way you can "append" a collection from one database to another.

Prior to version 2.4.3, you will also need to add back your indexes after you copy over your data. Starting with 2.4.3, this process is automatic, and you can disable it with --noIndexRestore.

According to the jQuery documentation of select():

Trigger the select event of each matched element. This causes all of the functions that have been bound to that select event to be executed, and calls the browser's default select action on the matching element(s).

There is your explanation why the jQuery select() won't work in this case.

Do you really need to do that programmatically?

Just considering the title: You could use a ShapeDrawable as android:background…

For example, let's define res/drawable/my_custom_background.xml as:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

and define android:background="@drawable/my_custom_background".

I've not tested but it should work.

Update:

I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/border"
    android:padding="10dip" >
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
    [... more TextView ...]
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
</LinearLayout>

and a res/drawable/border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
   <stroke
        android:width="5dip"
        android:color="@android:color/white" />
</shape>

Reported to work on a gingerbread device. Note that you'll need to relate android:padding of the LinearLayout to the android:width shape/stroke's value. Please, do not use @android:color/white in your final application but rather a project defined color.

You could apply android:background="@drawable/border" android:padding="10dip" to each of the LinearLayout from your provided sample.

As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…

Your problem resides clearly in the use of getBorder.set{Width,Height}(100);. Why do you do that in an onClick method?

I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.

To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

giammin's solution is partially incorrect. You SHOULD NOT remove that entire PropertyGroup from your solution. If you do, MSBuild's "DeployTarget=Package" feature will stop working. This feature relies on the "VSToolsPath" being set.

<PropertyGroup>
  <!-- VisualStudioVersion is incompatible with later versions of Visual Studio.  Removing. -->
  <!-- <VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion> -->
  <!-- VSToolsPath is required by MSBuild for features like "DeployTarget=Package" -->
  <VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
</PropertyGroup>
...
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />

In Expression Language you can just use the == or eq operator to compare object values. Behind the scenes they will actually use the Object#equals(). This way is done so, because until with the current EL 2.1 version you cannot invoke methods with other signatures than standard getter (and setter) methods (in the upcoming EL 2.2 it would be possible).

So the particular line

<c:when test="${lang}.equals(${pageLang})">

should be written as (note that the whole expression is inside the { and })

<c:when test="${lang == pageLang}">

or, equivalently

<c:when test="${lang eq pageLang}">

Both are behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals(jspContext.findAttribute("pageLang"))

If you want to compare constant String values, then you need to quote it

<c:when test="${lang == 'en'}">

or, equivalently

<c:when test="${lang eq 'en'}">

which is behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals("en")

@Override
public boolean onTouchEvent(MotionEvent event)
{
    int x = (int)event.getX();
    int y = (int)event.getY();

    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        case MotionEvent.ACTION_MOVE:
        case MotionEvent.ACTION_UP:
    }

    return false;
}

The three cases are so that you can react to different types of events, in this example tapping or dragging or lifting the finger again.

This is how it worked for me

first I find my platform-tools than I was using zshrc instead of bash_profile so I run this command first

echo 'export PATH=$HOME/Library/Android/sdk/platform-tools/' >> ~/.zshrc

next refresh terminal

source ~/.zshrc

Check if it worked

adb devices

result of this command must be something similar to this if so then it worked.

even after installing anaconda i got the same error and entering python3 showed this:

$ python3
Python 3.6.9 (default, Nov  7 2019, 10:44:02) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

enter this command: source ~/.bashrc (it is kind of restarting the terminal) after running the command enter python3 again:

$ python3

[GCC 7.3.0] :: Anaconda, Inc. on linux

>>> 

this means anaconda is added. now import pandas will work.

I also wondered that long time ago. I searched a bit in my history and I think that this post: http://lists.mysql.com/internals/34919 represents the semi-official position of MySQL (before Oracle's intervention ;))

In short:

this limitation stems only from the way in which this feature is currently implemented in the server and there are no other reasons for its existence.

So their explanation is "because it is implemented like this". Doesn't sound very scientific. I guess it all comes from some old code. This is suggested in the thread above: "carry-over from when only the first timestamp field was auto-set/update".

Cheers!

Ok, I solved it. Writing it for anyone who might be tired after a full day of non-stop coding & miss such a silly thing.

@RequestMapping(value="/fetch" , method=RequestMethod.GET)
    public @ResponseBody String fetchResult(@RequestParam("from") @DateTimeFormat(pattern="yyyy-MM-dd") Date fromDate) {
        //Content goes here
    }

Yes, it's simple. Just add the DateTimeFormat annotation.

Usefull fallback here: https://developer.mozilla.org/en-US/docs/Web/Events/MozOrientation

function orientationhandler(evt){


  // For FF3.6+
  if (!evt.gamma && !evt.beta) {
    evt.gamma = -(evt.x * (180 / Math.PI));
    evt.beta = -(evt.y * (180 / Math.PI));
  }

  // use evt.gamma, evt.beta, and evt.alpha 
  // according to dev.w3.org/geo/api/spec-source-orientation


}

window.addEventListener('deviceorientation',  orientationhandler, false);
window.addEventListener('MozOrientation',     orientationhandler, false);

UITextView supports data-detectors in OS3.0, whereas UILabel doesn't.

If you enable the data-detectors on the UITextView and your text contains URLs, phone numbers, etc. they will appear as links.

I'd do it like this:

[id^="product"] {
  ...
}

Ideally, use a class. This is what classes are for:

<div id="product176" class="product"></div>
<div id="product177" class="product"></div>
<div id="product178" class="product"></div>

And now the selector becomes:

.product {
  ...
}

You can do this:

$('.searchbychar').click(function () {
    var divID = '#' + this.id;
    $('html, body').animate({
        scrollTop: $(divID).offset().top
    }, 2000);
});

F.Y.I.

• You need to prefix a class name with a . (dot) like in your first line of code.
• $( 'searchbychar' ).click(function() {
• Also, your code $('.searchbychar').attr('id') will return a string ID not a jQuery object. Hence, you can not apply .offset() method to it.

you can probably use the latex style:

$\color{color-code}{your-text-here}$

To keep the whitespace between words, you also need to include the tilde ~.

answer to your question is simple order is not a object make it an array. var order = new Array(); order.push(/item to push/); when ever this error appears just check the left of which property the error is in this case it is push which is order[] so it is undefined.

Fixed the code for you:

ArrayList<Class> myArray= new ArrayList<Class>();

Please just go to your terminal then type:

$rm __pycache__

and it will be removed.

This should be the function you are looking for

Remove the alpha channel using this command in the folder 'Images.xcassets', this command will remove all alpha channels from your .png files and it will put the background color to white

The ALLOWED_HOSTS list should contain fully qualified host names, not urls. Leave out the port and the protocol. If you are using 127.0.0.1, I would add localhost to the list too:

ALLOWED_HOSTS = ['127.0.0.1', 'localhost']

You could also use * to match any host:

ALLOWED_HOSTS = ['*']

Quoting the documentation:

Values in this list can be fully qualified names (e.g. 'www.example.com'), in which case they will be matched against the request’s Host header exactly (case-insensitive, not including port). A value beginning with a period can be used as a subdomain wildcard: '.example.com' will match example.com, www.example.com, and any other subdomain of example.com. A value of '*' will match anything; in this case you are responsible to provide your own validation of the Host header (perhaps in a middleware; if so this middleware must be listed first in MIDDLEWARE_CLASSES).

Bold emphasis mine.

The status 400 response you get is due to a SuspiciousOperation exception being raised when your host header doesn't match any values in that list.

You may want to read this page of the MySQL manual. How a table gets locked is dependent on what type of table it is.

MyISAM uses table locks to achieve a very high read speed, but if you have an UPDATE statement waiting, then future SELECTS will queue up behind the UPDATE.

InnoDB tables use row-level locking, and you won't have the whole table lock up behind an UPDATE. There are other kind of locking issues associated with InnoDB, but you might find it fits your needs.

In this case no conditionals are needed to set the variable.

This one-liner XPath expression:

boolean(joined-subclass)

is true() only when the child of the current node, named joined-subclass exists and it is false() otherwise.

The complete stylesheet is:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

 <xsl:template match="class">
   <xsl:variable name="subexists"
        select="boolean(joined-subclass)"
   />

   subexists:  <xsl:text/>
   <xsl:value-of select="$subexists" />
 </xsl:template>
</xsl:stylesheet>

Do note, that the use of the XPath function boolean() in this expression is to convert a node (or its absense) to one of the boolean values true() or false().

    var inputElements = document.getElementsByTagName("input");

try it. it will works, enjoy

It is because the framework requires that two objects that are the same must have the same hashcode. If you override the equals method to do a special comparison of two objects and the two objects are considered the same by the method, then the hash code of the two objects must also be the same. (Dictionaries and Hashtables rely on this principle).

Here is my trick:

public class Main {

    public static void main(String[] args) throws Exception {

        System.out.println(Main.<String> getClazz());

    }

    static <T> Class getClazz(T... param) {

        return param.getClass().getComponentType();
    }

}

You can check the amef protocol, an example of C++ encoding in amef would be like,

    //Create a new AMEF object
    AMEFObject *object = new AMEFObject();

    //Add a child string object
    object->addPacket("This is the Automated Message Exchange Format Object property!!","adasd");   

    //Add a child integer object
    object->addPacket(21213);

    //Add a child boolean object
    object->addPacket(true);

    AMEFObject *object2 = new AMEFObject();
    string j = "This is the property of a nested Automated Message Exchange Format Object";
    object2->addPacket(j);
    object2->addPacket(134123);
    object2->addPacket(false);

    //Add a child character object
    object2->addPacket('d');

    //Add a child AMEF Object
    object->addPacket(object2);

    //Encode the AMEF obejct
    string str = new AMEFEncoder()->encode(object,false);

Decoding in java would be like,

    string arr = amef encoded byte array value;
    AMEFDecoder decoder = new AMEFDecoder()
    AMEFObject object1 = AMEFDecoder.decode(arr,true);

The Protocol implementation has codecs for both C++ and Java, the interesting part is it can retain object class representation in the form of name value pairs, I required a similar protocol in my last project, when i incidentally stumbled upon this protocol, i had actually modified the base library according to my requirements. Hope this helps you.

Assuming you are talking about JavaScript in an HTML document.

You can't do this directly since, as far as the JSP is concerned, it is outputting text, and as far as the page is concerned, it is just getting an HTML document.

You have to generate JavaScript code to instantiate the variable, taking care to escape any characters with special meaning in JS. If you just dump the data (as proposed by some other answers) you will find it falling over when the data contains new lines, quote characters and so on.

The simplest way to do this is to use a JSON library (there are a bunch listed at the bottom of http://json.org/ ) and then have the JSP output:

<script type="text/javascript">
    var myObject = <%= the string output by the JSON library %>;
</script>

This will give you an object that you can access like:

myObject.someProperty

in the JS.

AppcompatTextView now supports auto sizing starting from Support Library 26.0. TextView in Android O also works same way. More info can be found here. A simple demo app can be found here.

<LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:autoSizeTextType="uniform"
        app:autoSizeMinTextSize="12sp"
        app:autoSizeMaxTextSize="100sp"
        app:autoSizeStepGranularity="2sp"
      />

</LinearLayout>

What system are you on? It looks like you have a system with X11, but the DISPLAY environment variable was not properly set. Try executing the following command and then rerunning your program:

export DISPLAY=localhost:0

when you define the class A, in A.h, you explicitely say that the class has a member B.

You MUST include "B.h" in "A.h"

You could also use file_get_contents

 $url_a="http://127.0.0.1/get_value.php?line=a&shift=1&tgl=2017-01-01";
 $data_a=file_get_contents($url_a);

 echo $data_a;

steps to install maven :

1. download the maven file from http://maven.apache.org/download.cgi
2. $tar xvf apache-maven-3.5.4-bin.tar.gz
3. copy the apache folder to desired place $cp -R apache-maven-3.5.4 /Users/locals
4. go to apache directory $cd /Users/locals/apache-maven-3.5.4/
5. create .bash_profile $vim ~/.bash_profile
6. write these two command : export M2_HOME=/Users/manisha/apache-maven-3.5.4 export PATH=$PATH:$M2_HOME/bin 7 save and quit the vim :wq!
7. restart the terminal and type mvn -version

using json.loads will turn your data into a python dictionary.

Dictionaries values are accessed using ['key']

resp_str = {
  "name" : "ns1:timeSeriesResponseType",
  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",
  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",
  "value" : {
    "queryInfo" : {
      "creationTime" : 1349724919000,
      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",
      "criteria" : {
        "locationParam" : "[ALL:103232434]",
        "variableParam" : "[00060, 00065]"
      },
      "note" : [ {
        "value" : "[ALL:103232434]",
        "title" : "filter:sites"
      }, {
        "value" : "[mode=LATEST, modifiedSince=null]",
        "title" : "filter:timeRange"
      }, {
        "value" : "sdas01",
        "title" : "server"
      } ]
    }
  },
  "nil" : false,
  "globalScope" : true,
  "typeSubstituted" : false
}

would translate into a python diction

resp_dict = json.loads(resp_str)

resp_dict['name'] # "ns1:timeSeriesResponseType"

resp_dict['value']['queryInfo']['creationTime'] # 1349724919000

Javascript looks good. Try to run it after the the div has loaded. Try to run only when the document is ready. $(document).ready in jquery.

I think you had not yet import the private key as the message error said, To import public/private key from gnupg:

gpg --import mypub_key
