Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

SELECT employee_number, course_code, MAX(course_completion_date) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

Join the table with itself and give it two different aliases (A and B in the following example). This allows to compare different rows of the same table.

SELECT DISTINCT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id AND A.[Adress Code] < B.[Adress Code]
WHERE
    A.Address <> B.Address

The "less than" comparison < ensures that you get 2 different addresses and you don't get the same 2 address codes twice. Using "not equal" <> instead, would yield the codes as (1, 2) and (2, 1); each one of them for the A alias and the B alias in turn.

The join clause is responsible for the pairing of the rows where as the where-clause tests additional conditions.

The query above works with any address codes. If you want to compare addresses with specific address codes, you can change the query to

SELECT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id
WHERE                     
    A.[Adress Code] = 1 AND
    B.[Adress Code] = 2 AND
    A.Address <> B.Address

I imagine that this might be useful to find customers having a billing address (Adress Code = 1 as an example) differing from the delivery address (Adress Code = 2) .

Every time you create an ajax request you could use a variable to store it:

var request = $.ajax({
    type: 'POST',
    url: 'someurl',
    success: function(result){}
});

Then you can abort the request:

request.abort();

You could use an array keeping track of all pending ajax requests and abort them if necessary.

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.

For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:

$ php -i | grep -i soap

to ensure that it is the PHP extension that is missing.

Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.

In Ubuntu/Debian you can search with:

$ apt-cache search php | grep -i soap

or in RHEL/Fedora you can search with:

$ yum search php | grep -i soap

There are usually two PHP SOAP packages available to you, usually php-soap and php-nusoap. php-soap is typically what you get with configuring PHP with --enable-soap.

In Ubuntu/Debian you can install with:

$ sudo apt-get install php-soap

Or in RHEL/Fedora you can install with:

$ sudo yum install php-soap

After the installation, you might need to place an ini file and restart Apache.

Make sure that you're using the same Servlet API specification that your Web container supports. Refer to this chart if you're using Tomcat: http://tomcat.apache.org/whichversion.html

The Web container that you use will definitely have the API jars you require.

Tomcat 6 for example has it in apache-tomcat-6.0.26/lib/servlet-api.jar

I like Andrew's suggestion, and in fact the CSS rule only needs to be:

:checked + label {
   font-weight: bold;
}

I like to rely on implicit association of the label and the input element, so I'd do something like this:

<label>
   <input type="checkbox"/>
   <span>Bah</span>
</label>

with CSS:

:checked + span {
    font-weight: bold;
}

Example: http://jsfiddle.net/wrumsby/vyP7c/

For getting the list of filenames in a specified folder, you can use:

fs.readdir(directory_path, callback_function)

This will return a list which you can parse by simple list indexing like file[0],file[1], etc.

SELECT Q.FK
      ,ISNULL(T1.Field1, T2.Field2) AS Field
FROM (SELECT FK FROM Table1
        UNION
      SELECT FK FROM Table2) AS Q
LEFT JOIN Table1 AS T1 ON T1.FK = Q.FK
LEFT JOIN Table2 AS T2 ON T2.FK = Q.FK

If there is one table, write Table1 instead of Table2

I would like to expand the answer of Jason Bunting

like this

ActionResult action = new SampelController().Index(2, "text");
return action;

And Eli will be here for something idea on how to make it generic variable

Can get all types of controller

Open Terminal and type:

pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages

except instead of

/Users/Bob/Library/Python/3.8/lib/python/site-packages

you would use whatever directory you want.

We were using code that resembles the code above in a previous post using

...
String signature = new BigInteger(1,md5.digest()).toString(16);
...

However, watch out for using BigInteger.toString() here, as it will truncate leading zeros... (for an example, try s = "27", checksum should be "02e74f10e0327ad868d138f2b4fdd6f0")

I second the suggestion to use Apache Commons Codec, I replaced our own code with that.

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

As far as I remember, this is controlled by browser settings. In other words: user can chose whether they would like to open new tab in the background or foreground. Also they can chose whether new popup should open in new tab or just... popup.

For example in firefox preferences:

Notice the last option.

I use to always add a new target on my solutions for achieving this.

<Target Name="clean_folders">
  <RemoveDir Directories=".\ProjectName\bin" />
  <RemoveDir Directories=".\ProjectName\obj" />
  <RemoveDir Directories="$(ProjectVarName)\bin" />
  <RemoveDir Directories="$(ProjectVarName)\obj" />
</Target>

And you can call it from command line

msbuild /t:clean_folders

This can be your batch file.

msbuild /t:clean_folders
PAUSE

If nobody has pulled it, you can probably do something like

git push remote +branch^1:remotebranch

which will forcibly update the remote branch to the last but one commit of your branch.

You can append array of Data at the end of custom state:

  const [vehicleData, setVehicleData] = React.useState<any[]>([]);
  setVehicleData(old => [...old, ...newArrayData]);

For example, In below, you appear an example of axios:

  useEffect(() => {
    const fetchData = async () => {
      const result = await axios(
        {
          url: `http://localhost:4000/api/vehicle?page=${page + 1}&pageSize=10`,
          method: 'get',
        }
      );
      setVehicleData(old => [...old, ...result.data.data]);
    };

    fetchData();
  }, [page]);

This is an interesting variation on the theme. At first and second glances you would assume the true branch is taken. Not so!

bool? flag = null;
if (!flag ?? true)
{
    // false branch
}
else
{
    // true branch
}

The way to get what you want is to do this:

if (!(flag ?? true))
{
    // false branch
}
else
{
    // true branch
}

No, but you can do this almost as easily.

Go here:

https://romannurik.github.io/AndroidAssetStudio/

Build your icons using that page, and then download the zip package. Unzip it into the right directory and it'll overwrite all the drawable-*/ic_launcher.png correctly.

The URL is relative to the location of the CSS file, so this should work for you:

url('../../images/image.jpg')

The relative URL goes two folders back, and then to the images folder - it should work for both cases, as long as the structure is the same.

From https://www.w3.org/TR/CSS1/#url:

Partial URLs are interpreted relative to the source of the style sheet, not relative to the document

Centering both horizontally and vertically

Actually, having the height and width in percents makes centering it even easier. You just offset the left and top by half of the area not occupied by the div.

So if you height is 40%, 100% - 40% = 60%. So you want 30% above and below. Then top: 30% does the trick.

See the example here: http://dabblet.com/gist/5957545

Centering only horizontally

Use inline-block. The other answer here will not work for IE 8 and below, however. You must use a CSS hack or conditional styles for that. Here is the hack version:

See the example here: http://dabblet.com/gist/5957591

.inlineblock { 
    display: inline-block;
    zoom: 1;
    display*: inline; /* ie hack */
}

EDIT

By using media queries you can combine two techniques to achive the effect you want. The only complication is height. You use a nested div to switch between % width and

http://dabblet.com/gist/5957676

@media (max-width: 1000px) {
    .center{}
    .center-inner{left:25%;top:25%;position:absolute;width:50%;height:300px;background:#f0f;text-align:center;max-width:500px;max-height:500px;}
}
@media (min-width: 1000px) {
    .center{left:50%;top:25%;position:absolute;}
    .center-inner{width:500px;height:100%;margin-left:-250px;height:300px;background:#f0f;text-align:center;max-width:500px;max-height:500px;}
}

Both syntaxes are correct. But the result would be Array. You probably want to do something like this:

foreach ($tmpArray[1] as $value) {
  echo $value[0];
  foreach($value[1] as $val){
    echo $val;
  }
}

This will print out the string "two" ($value[0]) and the integers 4, 5 and 6 from the array ($value[1]).

I know it's kinda too late to reply to this post but since I don't see any clear answer i'd do it anyway...

you might wanna check out the MANIFEST.MF in META-INF on your eclipse.

then you might need to add the path of your class files like..

Class-Path: WEB-INF/classes

You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

Modern browsers now support the crypto.subtle API, which provides native encryption and decryption functions (async no less!) using one of these method: AES-CBC, AES-CTR, AES-GCM, or RSA-OAEP.

Below is the two line of snippet using Java 1.8 Time API for your Requirement.

LocalDate localDate = LocalDate.of(Integer.valueOf(year),Integer.valueOf(month),Integer.valueOf(day));
String dayOfWeek = String.valueOf(localDate.getDayOfWeek());

For linux:

$ strace sqlplus -L scott/tiger@orcl 2>&1| grep -i 'open.*tnsnames.ora'

shows something like this:

open("/opt/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora",O_RDONLY)=7

Changing to

$ strace sqlplus -L scott/tiger@orcl 2>&1| grep -i 'tnsnames.ora'

will show all the file paths that are failing.

I faced the same problem here's the solution:(Explained)

I am running Anaconda version 4.3.22 and a python3.6.1 environment, and had this problem. Here's the history and the fix:

pip uninstall opencv-python # -- the original step. failed.

ImportError: DLL load failed: The specified module could not be found.

I did this into my python3.6 environment and got this error.

python -m pip install opencv-python # same package as above.
conda install -c conda-forge opencv # separate install parallel to opencv
pip-install opencv-contrib-python # suggested by another user here. doesn't resolve it.

Next, I tried downloading python3.6 and putting the python3.dll in the folder and in various folders. nothing changed.

finally, this fixed it:

pip uninstall opencv-python

(the other conda-forge version is still installed) This left only the conda version, and that works in 3.6.

working!

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

1. find your php.ini
2. make sure the directive extension_dir=C:\path\to\server\php\ext is set and adjust the path (set your PHP extension dir)
3. make sure the directive extension=php_mbstring.dll is set (uncommented)

If this doesn't work and the php_mbstring.dll file is missing, then the PHP installation of this stack is simply broken.

This is the problem:

C:\Users\Noob\csharp>csc test.cs

You haven't added a reference to the DLL. You need something like:

C:\Users\Noob\csharp>csc test.cs /r:SnarlNetwork.dll

(or whatever the assembly is called).

Alternatively, if you haven't got it as a separate library, just compile both files:

C:\Users\Noob\csharp>csc test.cs SnarlNetwork.cs

If you haven't compiled an assembly but want to, you can use:

csc /target:library /out:SnarlNetwork.dll SnarlNetwork.cs

csc Test.cs /r:SnarlNetwork.dll

(In fact, specifying the output file is unnecessary in this particular case, but it's still clearer...)

Just an information: let us all remember that the Image class is actually an abstract class and referencing a variable of this with a BufferedImage only stores or returns any Object's memory adress.

Also, wherefore, static java.awt.image.imageIO's read() method returns a BufferedImage object, therefore no doubt that using operator/expression instanceof BufferedImage on that object will return true.

In fact, being abstract, Image class has such method signatures as:

1. public abstract Graphics getGraphics()
2. public abstract ImageProducer getSource()

among others.

I emphasize, an actual Image variable only holds memory adress of a concrete Image-subclass object, almost like pointers in C, C++, Ada, etc.

If you're introduced or advanced in those languages, and also of Java interface instances like Runnable, javax.sound.Clip, AWT's Shape, etc.. . Take note that Image has: public abstract Image getScaledInstance(...) - you get the point. (Of course, scaling in 2D Graphics programming is interchangeable to resizing, for which precision is desirable).

But in an impossible case when herein ImageIO method return ! (instanceof BufferedImage) just create a new BufferedImage object with this ImgObjNotInstncfBufImg apassed to one of its constructor argument. Then, at (rational) will manipulate this in the logic of your code.

Anyways, the Affine Transform class is appropriate for transforming Shapes and Images to thier scaled, rotated, relocated, etc forms, so I recommend you to study about using an "affine transform".

Take note that you can manipulate the actual pixels in such Image's Raster - well another technical 2D Graphics jargon which must be referenced from a technical glossary - which perhaps a excercised skill in Java ways of binary blitwise operations will be needed, in types of Image buffers that store individual color attributes in a compact in of 32-bytes - 7-bits each for the alpha and RGB values.

I suspect your gonna use it in layering images. So, FINALLY, the rational is that you only reference BufferedImage with the abstract Image, and if ever your Image object isn't a BufferedImage one yet, then you can just make an image out of this related-but-non-BufferedImage-instance without having to worry about any conversion, casting, autoboxing or whatever; manipulating a BufferedImage really means manipulating also the underlying root Image data-bearing object that it points to.

Okay, finished; I think I certainly extracted and splintered out what deadlock you may have thought you are facing to. As I have said abstract classes in java, and also interfaces, are very much the equivaleng of the low-level, more-close-to-hardware operators called pointers in other languages.

With the Javascript localStorage class, you can use the default local storage of your browser to save (key,value) pairs and then retrieve these values on whichever page you need using the key. Example - Pageone.html -

<script>
    localStorage.setItem("firstname", "Smith");
</script>  

Pagetwo.html -

<script>
    var name=localStorage.getItem("firstname");
</script>  

Not just only when specify required, I also got this issue when using min and max e.g.

<input type="number" min="1900" max="2090" />

That field can be hidden and shown based on other radio value. So, for temporary solution, I removed the validation.

If you want read Session value in javascript.This code help for you.

<script type='text/javascript'> var userID='@Session["userID"]'; </script>

I only have 10 or so views in my production databases. I use several for columns I use all the time. One set I use come from 7 tables, some with outer joins and rather than rewrite that constantly I only have to call that view in a select and make one or 2 joins. To me it is just a time saver.

reflect.DeepEqual is often incorrectly used to compare two like structs, as in your question.

cmp.Equal is a better tool for comparing structs.

To see why reflection is ill-advised, let's look at the documentation:

Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal.

....

numbers, bools, strings, and channels - are deeply equal if they are equal using Go's == operator.

If we compare two time.Time values of the same UTC time, t1 == t2 will be false if their metadata timezone is different.

go-cmp looks for the Equal() method and uses that to correctly compare times.

Example:

m1 := map[string]int{
    "a": 1,
    "b": 2,
}
m2 := map[string]int{
    "a": 1,
    "b": 2,
}
fmt.Println(cmp.Equal(m1, m2)) // will result in true

It seems to be true so far. The only SDK available from Apple only targets the macOS environment. I've been upset about that, but I'm looking into buying a mac now, just to do iPhone development. I really dislike what they are doing, and I hope a good SDK come out for other environments, such as Linux and Windows.

Obstacles regarding the SDK:

The iPhone SDK and free software: not a match

Apple's recently released a software development kit (SDK) for the iPhone, but if you were hoping to port or develop original open source software with it, the news isn't good. Code signing and nondisclosure conditions make free software a no-go.

The SDK itself is a free download, with which you can write programs and run them on a software simulator. But in order to actually release software you've written, you must enroll in the iPhone Developer Program -- a step separate from downloading the SDK, and one that requires Apple's approval.

I think it's rather elitist for them to think only macOS users are good enough to write programs for their phone, and the fact you need to buy a $100 license if you want to publish your stuff, really makes it more difficult for the hobbyist programmer. Though, if that's what you need to do, I'm planning on jumping through their hoops; I'd really like to get some stuff developed on my iPhone.

As @KyssTao has been saying, help(dates.num2date) says that the x has to be a float giving the number of days since 0001-01-01 plus one. Hence, 19910102 is not 2/Jan/1991, because if you counted 19910101 days from 0001-01-01 you'd get something in the year 54513 or similar (divide by 365.25, number of days in a year).

Use datestr2num instead (see help(dates.datestr2num)):

new_x = dates.datestr2num(date) # where date is '01/02/1991'

I know you already accepted the other answer, but if you want to do this as a DataFrame, just use groupBy and agg. Assuming you had a DF already created (with columns named "col1", "col2", etc) you could do:

myDF.groupBy($"col1", $"col3", $"col4").agg($"col1", max($"col2"), $"col3", $"col4")

Note that in this case, I chose the Max of col2, but you could do avg, min, etc.

At date git prompts:

1. use "git rm --cached <file>..." to unstage if files were not in the repo. It unstages the files keeping them there.
2. use "git reset HEAD <file>..." to unstage if the files were in the repo, and you are adding them as modified. It keeps the files as they are, and unstages them.

At my knowledge you cannot undo the git add -- but you can unstage a list of files as mentioned above.

After hours of frustration... here's what i discovered.

1. Ignore the installation documentation and all the command line, node.js stuff (seriously you will waste hours on this.
2. Go to github and simply download the PhoneGap master .zip
3. In that zip are project files for window phone, etc platform... just use those templates.

I don't know how such an easy process could have worse documentation. It as if it was written by lawyers.

I've just spent quite some time troubleshooting this very problem. None of the proposed solutions worked. Turned out that our sysadmin by mistake assigned the same static IP to two unrelated servers belonging to different groups, but sitting on the same network. The end results were intermittently dropped vnc connections, browser that had to be refreshed several times to fetch the web page, and other strange things.

as_json

You should use as_json method which converts ActiveRecord objects to Ruby Hashes despite its name

tasks_records = TaskStoreStatus.all
tasks_records = tasks_records.as_json

# You can now add new records and return the result as json by calling `to_json`

tasks_records << TaskStoreStatus.last.as_json
tasks_records << { :task_id => 10, :store_name => "Koramanagala", :store_region => "India" }
tasks_records.to_json

serializable_hash

You can also convert any ActiveRecord objects to a Hash with serializable_hash and you can convert any ActiveRecord results to an Array with to_a, so for your example :

tasks_records = TaskStoreStatus.all
tasks_records.to_a.map(&:serializable_hash)

And if you want an ugly solution for Rails prior to v2.3

JSON.parse(tasks_records.to_json) # please don't do it

In Ruby IO module documentation, I suppose.

something like

for (int rows = 0; rows < dataGrid.Rows.Count; rows++)
{
     for (int col= 0; col < dataGrid.Rows[rows].Cells.Count; col++)
    {
        string value = dataGrid.Rows[rows].Cells[col].Value.ToString();

    }
} 

example without using index

foreach (DataGridViewRow row in dataGrid.Rows)
{ 
    foreach (DataGridViewCell cell in row.Cells)
    {
        string value = cell.Value.ToString();

    }
}

From the documentation:

contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')

Type: String

When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and:

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String

The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

They're essentially the opposite of what you thought they were.

Create MongoDB Service in Windows. First Open cmd with administrator

mongod --port 27017 --dbpath "a mongodb storage actual path e.g: d:\mongo_storage\data" --logpath="a log path e.g: d:\mongo_storage\log\log.txt" --install --serviceName "MongoDB"

After that

Start Service

net start MongoDB

Stop Service

net stop MongoDB

These steps will do it:

git reset --hard HEAD
git clean -f -x -d -n

then without -n

This will take care of all local changes. Now the commits...

git status

and note the line such as:

Your branch is ahead of 'xxxx' by N commits.

Take a note of number 'N' now:

git reset --hard HEAD~N
git pull

and finally:

git status

should show nothing to add/commit. All clean.

However, a fresh clone can do the same (but is much slow).

===Updated===

As my git knowledge slightly improved over the the time, I have come up with yet another simpler way to do the same. Here is how (#with explanation). While in your working branch:

git fetch # This updates 'remote' portion of local repo. 
git reset --hard origin/<your-working-branch>
# this will sync your local copy with remote content, discarding any committed
# or uncommitted changes.

Although your local commits and changes will disappear from sight after this, it is possible to recover committed changes, if necessary.

If you need to install an older version (for example 0.25):

pod _0.25.0_ install

None of those are precisely the same, though they will all have the same net effect.

The difference between the first and the second is that if you happen to be on the main application thread when executing the code, the first one (runOnUiThread()) will execute the Runnable immediately. The second one (post()) always puts the Runnable at the end of the event queue, even if you are already on the main application thread.

The third one, assuming you create and execute an instance of BackgroundTask, will waste a lot of time grabbing a thread out of the thread pool, to execute a default no-op doInBackground(), before eventually doing what amounts to a post(). This is by far the least efficient of the three. Use AsyncTask if you actually have work to do in a background thread, not just for the use of onPostExecute().

I've tried to resolve this issue in some generic, MVVM way, but I always find that I end up unnecessary complex logic. To achieve close behavior I have made an exception from the rule of no code behind and resorted to simply using good ol' events in code behind:

XAML:

<Button Content="Close" Click="OnCloseClicked" />

Code behind:

private void OnCloseClicked(object sender, EventArgs e)
{
    Visibility = Visibility.Collapsed;
}

Although I wish this would be better supported using commands/MVVM, I simply think that there is no simpler and more clear solution than using events.

button::-moz-focus-inner {
  border: 0;
}

Try to install "Moesif CORS" extension if you are facing issue in google chrome. As it is cross origin request, so chrome is not accepting a response even when the response status code is 200

Cast to long or cast to int, be aware of the following.

These functions are one of the view functions in Excel VBA that are depending on the system regional settings. So if you use a comma in your double like in some countries in Europe, you will experience an error in the US.

E.g., in european excel-version 0,5 will perform well with CDbl(), but in US-version it will result in 5. So I recommend to use the following alternative:

Public Function CastLong(var As Variant)

    ' replace , by .
    var = Replace(var, ",", ".")        

    Dim l As Long
    On Error Resume Next
    l = Round(Val(var))

    ' if error occurs, l will be 0
    CastLong = l

End Function

' similar function for cast-int, you can add minimum and maximum value if you like
' to prevent that value is too high or too low.
Public Function CastInt(var As Variant)

    ' replace , by .
    var = Replace(var, ",", ".")

    Dim i As Integer
    On Error Resume Next
    i = Round(Val(var))

    ' if error occurs, i will be 0
    CastInt = i

End Function

Of course you can also think of cases where people use commas and dots, e.g., three-thousand as 3,000.00. If you require functionality for these kind of cases, then you have to check for another solution.

I would combine node-http-proxy and express.

node-http-proxy will support a proxy inside your node.js web server via RoutingProxy (see the example called Proxy requests within another http server).

Inside your custom server logic you can do authentication using express. See the auth sample here for an example.

Combining those two examples should give you what you want.

You can get the events from pygame and then watch out for the KEYDOWN event, instead of looking at the keys returned by get_pressed()(which gives you keys that are currently pressed down, whereas the KEYDOWN event shows you which keys were pressed down on that frame).

What's happening with your code right now is that if your game is rendering at 30fps, and you hold down the left arrow key for half a second, you're updating the location 15 times.

events = pygame.event.get()
for event in events:
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            location -= 1
        if event.key == pygame.K_RIGHT:
            location += 1

To support continuous movement while a key is being held down, you would have to establish some sort of limitation, either based on a forced maximum frame rate of the game loop or by a counter which only allows you to move every so many ticks of the loop.

move_ticker = 0
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
    if move_ticker == 0:
        move_ticker = 10
        location -= 1
        if location == -1:
            location = 0
if keys[K_RIGHT]:
    if move_ticker == 0:   
        move_ticker = 10     
        location+=1
        if location == 5:
            location = 4

Then somewhere during the game loop you would do something like this:

if move_ticker > 0:
    move_ticker -= 1

This would only let you move once every 10 frames (so if you move, the ticker gets set to 10, and after 10 frames it will allow you to move again)

Your response must return some sort of Response object. You can't just return an object.

So change it to something like:

return Response::json($promotion);

or my favorite using the helper function:

return response()->json($promotion);

If returning a response doesn't work it may be some sort of encoding issue. See this article: The Response content must be a string or object implementing __toString(), \"boolean\" given."

You need to add a dataType - http://api.jquery.com/jQuery.ajax/

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt",
            dataType: "text",
            success : function (data) {
                $(".text").html(data);
            }
        });
    });
}); 

Working one liner if you want a single result from the collection:

$ipAddy = [System.Net.Dns]::GetHostAddresses("yahoo.com")[0].IPAddressToString;

Late contribution but just came across something similar in Python datetime and pandas give different timestamps for the same date.

If you have timezone-aware datetime in pandas, technically, tz_localize(None) changes the POSIX timestamp (that is used internally) as if the local time from the timestamp was UTC. Local in this context means local in the specified timezone. Ex:

import pandas as pd

t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H', tz="US/Central")
# DatetimeIndex(['2013-05-18 12:00:00-05:00', '2013-05-18 13:00:00-05:00'], dtype='datetime64[ns, US/Central]', freq='H')

t_loc = t.tz_localize(None)
# DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], dtype='datetime64[ns]', freq='H')

# offset in seconds according to timezone:
(t_loc.values-t.values)//1e9
# array([-18000, -18000], dtype='timedelta64[ns]')

Note that this will leave you with strange things during DST transitions, e.g.

t = pd.date_range(start="2020-03-08 01:00:00", periods=2, freq='H', tz="US/Central")
(t.values[1]-t.values[0])//1e9
# numpy.timedelta64(3600,'ns')

t_loc = t.tz_localize(None)
(t_loc.values[1]-t_loc.values[0])//1e9
# numpy.timedelta64(7200,'ns')

In contrast, tz_convert(None) does not modify the internal timestamp, it just removes the tzinfo.

t_utc = t.tz_convert(None)
(t_utc.values-t.values)//1e9
# array([0, 0], dtype='timedelta64[ns]')

My bottom line would be: stick with timezone-aware datetime if you can or only use t.tz_convert(None) which doesn't modify the underlying POSIX timestamp. Just keep in mind that you're practically working with UTC then.

I'm surprised that nobody seems to have ever mentioned that you can use XDocument / XElement which are available in .NET 4.0 and make it much easier to output XML.

I had the same issue. Rather than figure out the MVC code, I opted for a cheap hack that seems to work. In my Global.asax class:

member x.Application_EndRequest() =
  if x.Response.StatusCode = 401 then 
      let redir = "?redirectUrl=" + Uri.EscapeDataString x.Request.Url.PathAndQuery
      if x.Request.Url.LocalPath.ToLowerInvariant().Contains("admin") then
          x.Response.Redirect("/Login/Admin/" + redir)
      else
          x.Response.Redirect("/Login/Login/" + redir)

If anyone wants to enable dark mode, you may follow the below steps

• Open your Notepad++, and select “Settings” on the menu bar, and choose “Style configurator”.
• Select theme “Obsidian” (you can choose other dark themes)
• Click on Save&Colse

You can type about:debug in some of the mobile browsers to pull up a JavaScript console.

Yes, this is a classpath issue. You need to tell the compiler and runtime that the directory where your .class files live is part of the CLASSPATH. The directory that you need to add is the parent of the "com" directory at the start of your package structure.

You do this using the -classpath argument for both javac.exe and java.exe.

Should also ask how the 3rd party classes you're using are packaged. If they're in a JAR, and I'd recommend that you have them in one, you add the .jar file to the classpath:

java -classpath .;company.jar foo.bar.baz.YourClass

Google for "Java classpath". It'll find links like this.

One more thing: "import" isn't loading classes. All it does it save you typing. When you include an import statement, you don't have to use the fully-resolved class name in your code - you can type "Foo" instead of "com.company.thing.Foo". That's all it's doing.

Once I required 2-D arrayList and I created using List and ArrayList and the code is as follows:

import java.util.*;

public class ArrayListMatrix {

    public static void main(String args[]){

        List<ArrayList<Integer>> a = new ArrayList<>();

        ArrayList<Integer> a1 = new ArrayList<Integer>();
        ArrayList<Integer> a2 = new ArrayList<Integer>();
        ArrayList<Integer> a3 = new ArrayList<Integer>();


        a1.add(1);
        a1.add(2);
        a1.add(3);

        a2.add(4);
        a2.add(5);
        a2.add(6);

        a3.add(7);
        a3.add(8);
        a3.add(9);

        a.add(a1);
        a.add(a2);
        a.add(a3);


        for(ArrayList obj:a){

            ArrayList<Integer> temp = obj;

            for(Integer job : temp){
                System.out.print(job+" ");
            }
            System.out.println();
        }
    }
}

Output:

1 2 3

4 5 6

.gitignore will only ignore files that you haven't already added to your repository.

If you did a git add ., and the file got added to the index, .gitignore won't help you. You'll need to do git rm sites/default/settings.php to remove it, and then it will be ignored.

Start your activity with request code :

StartActivityForResult(intent,1234);

And you can close it from any other activity like this :

finishActivity(1234);

LINQ is very effective and easy to use on Lists rather than DataTable. I can see the above answers have a loop(for, foreach), which I will not prefer.

So the best thing to select a perticular column from a DataTable is just use a DataView to filter the column and use it as you want.

Find it here how to do this.

DataView dtView = new DataView(dtYourDataTable);
DataTable dtTableWithOneColumn= dtView .ToTable(true, "ColumnA");

Now the DataTable dtTableWithOneColumn contains only one column(ColumnA).

I haven't played around with it much but eclipse/pydev feels nice.

On Mac OS 10.15.1, I got the same error even after accepted all the licenses by running sdkmanager --licenses It worked after I updated the ANDROID_HOME path configuration in the ~/.bash_profile to the following

export ANDROID_HOME=/Users/your_username/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
export PATH=$PATH:~/Library/Android/sdk/platform-tools

And reload the ~/.bash_profile

source ~/.bash_profile 

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

A JavaScript function must first be made that holds what you want to be done:

function print() { console.log("Hello World!") }

and then that function must be called in the onClick method from inside an element:

<a onClick="print()"> ... </a>

You can learn more about modal interactions directly from the Bootstrap 3 documentation found here: http://getbootstrap.com/javascript/#modals

Your modal bind is also incorrect. It should be something like this, where "myModal" = ID of element:

$('#myModal').modal(options)

In other words, if you truly want to keep what you already have, put a "#" in front GSCCModal and see if that works.

It is also not very wise to have an onClick bound to a div element; something like a button would be more suitable.

Hope this helps!

Try to put stateHidden on as your activity windowSoftInputMode value

http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode

For example for your Activity:

this.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

So here is my solution (similar to John Vance's answer):

First go here and get a function to detect mobile browsers.

http://detectmobilebrowsers.com/

They have a lot of different ways to detect if you are on mobile, so find one that works with what you are using.

Your HTML page (pseudo code):

If Mobile Then
    <input id="selling-date" type="date" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />
else
    <input id="selling-date" type="text" class="date-picker" readonly="readonly" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />

JQuery:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max  
    });
});

This way you can still use native date selectors in mobile while still setting the min and max dates either way.

The field for non mobile should be read only because if a mobile browser like chrome for ios "requests desktop version" then they can get around the mobile check and you still want to prevent the keyboard from showing up.

However if the field is read only it could look to a user like they cant change the field. You could fix this by changing the CSS to make it look like it isn't read only (ie change border-color to black) but unless you are changing the CSS for all input tags you will find it hard to keep the look consistent across browsers.

To get arround that I just add a calendar image button to the date picker. Just change your JQuery code a bit:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max,
        showOn: "both",
        buttonImage: "images/calendar.gif",
        buttonImageOnly: true,
        buttonText: "Select date"
    });
});

Note: you will have to find a suitable image.

Not sure if this is the best way, but it works.

if (cartDiv == null) {
    cartDiv = "<div id='unique_id'></div>"; // document.createElement('div');
    document.body.appendChild(cartDiv);
}

Yes it should be possible, even if the site is from another domain.

For example, in an HTML page on my site I have an iFrame whose contents are sourced from another website. The iFrame content is a single select field.

I need to be able to read the selected value on my site. In other words, I need to use the select list from another domain inside my own application. I do not have control over any server settings.

Initially therefore we might be tempted to do something like this (simplified):

HTML in my site:

<iframe name='select_frame' src='http://www.othersite.com/select.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>

HTML contents of iFrame (loaded from select.php on another domain):

<select id='select_name'>
    <option value='john'>John</option>
    <option value='jim' selected>Jim</option>
</select>

jQuery:

$('input:button[name=save]').click(function() {
    var name = $('iframe[name=select_frame]').contents().find('#select_name').val();
});

However, I receive this javascript error when I attempt to read the value:

Blocked a frame with origin "http://www.myownsite.com" from accessing a frame with origin "http://www.othersite.com". Protocols, domains, and ports must match.

To get around this problem, it seems that you can indirectly source the iFrame from a script in your own site, and have that script read the contents from the other site using a method like file_get_contents() or curl etc.

So, create a script (for example: select_local.php in the current directory) on your own site with contents similar to this:

PHP content of select_local.php:

<?php
    $url = "http://www.othersite.com/select.php?" . $_SERVER['QUERY_STRING'];
    $html_select = file_get_contents($url);
    echo $html_select;
?>

Also modify the HTML to call this local (instead of the remote) script:

<iframe name='select_frame' src='select_local.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>

Now your browser should think that it is loading the iFrame content from the same domain.

In Dojo 1.7 or newer, use domConstruct.empty(String|DomNode):

require(["dojo/dom-construct"], function(domConstruct){
  // Empty node's children byId:
  domConstruct.empty("someId");
});

In older Dojo, use dojo.empty(String|DomNode) (deprecated at Dojo 1.8):

dojo.empty( id or DOM node );

Each of these empty methods safely removes all children of the node.

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

GitLab 12.1 (July 2019) introduces a difference:

"Merge Requests for Confidential Issues"

When discussing, planning and resolving confidential issues, such as security vulnerabilities, it can be particularly challenging for open source projects to remain efficient since the Git repository is public.

As of 12.1, it is now possible for confidential issues in a public project to be resolved within a streamlined workflow using the Create confidential merge request button, which helps you create a merge request in a private fork of the project.

See "Confidential issues" from issue 58583.

A similar feature exists in GitHub, but involves the creation of a special private fork, called "maintainer security advisory".

GitLab 13.5 (Oct. 2020) will add reviewers, which was already available for GitHub before.

Restarting the IIS windows service (World Wide Web Publishing Service) and then starting the application pool has worked for me. However, as the top answer suggests it may have just been the waiting that caused it to subsequently work.

Dir("C:\Documents\myfile.pdf")

will return the file name, but only if it exists.

I don't understand what you want, but You can detect currently foreground/background application with ActivityManager.getRunningAppProcesses() call.

Something like,

class ForegroundCheckTask extends AsyncTask<Context, Void, Boolean> {

  @Override
  protected Boolean doInBackground(Context... params) {
    final Context context = params[0].getApplicationContext();
    return isAppOnForeground(context);
  }

  private boolean isAppOnForeground(Context context) {
    ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
    if (appProcesses == null) {
      return false;
    }
    final String packageName = context.getPackageName();
    for (RunningAppProcessInfo appProcess : appProcesses) {
      if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
        return true;
      }
    }
    return false;
  }
}

// Use like this:
boolean foregroud = new ForegroundCheckTask().execute(context).get();

Also let me know if I misunderstand..

UPDATE: Look at this SO question Determining the current foreground application from a background task or service fore more information..

Thanks..

You can do it with ViewModels like how you passed data from your controller to view.

Assume you have a viewmodel like this

public class ReportViewModel
{
   public string Name { set;get;}
}

and in your GET Action,

public ActionResult Report()
{
  return View(new ReportViewModel());
}

and your view must be strongly typed to ReportViewModel

@model ReportViewModel
@using(Html.BeginForm())
{
  Report NAme : @Html.TextBoxFor(s=>s.Name)
  <input type="submit" value="Generate report" />
}

and in your HttpPost action method in your controller

[HttpPost]
public ActionResult Report(ReportViewModel model)
{
  //check for model.Name property value now
  //to do : Return something
}

OR Simply, you can do this without the POCO classes (Viewmodels)

@using(Html.BeginForm())
{
   <input type="text" name="reportName" />
   <input type="submit" />
}

and in your HttpPost action, use a parameter with same name as the textbox name.

[HttpPost]
public ActionResult Report(string reportName)
{
  //check for reportName parameter value now
  //to do : Return something
}

EDIT : As per the comment

If you want to post to another controller, you may use this overload of the BeginForm method.

@using(Html.BeginForm("Report","SomeOtherControllerName"))
{
   <input type="text" name="reportName" />
   <input type="submit" />
}

Passing data from action method to view ?

You can use the same view model, simply set the property values in your GET action method

public ActionResult Report()
{
  var vm = new ReportViewModel();
  vm.Name="SuperManReport";
  return View(vm);
}

and in your view

@model ReportViewModel
<h2>@Model.Name</h2>
<p>Can have input field with value set in action method</p>
@using(Html.BeginForm())
{
  @Html.TextBoxFor(s=>s.Name)
  <input type="submit" />
}

An extension to Joachim Isaksson's answer: Quite often I need something from the middle of a long file, e.g. lines 5001 to 5020, in which case you can combine head with tail:

head -5020 file.txt | tail -20 | grep x

This gets the first 5020 lines, then shows only the last 20 of those, then pipes everything to grep.

(Edited: fencepost error in my example numbers, added pipe to grep)

In PHP arrays are passed to functions by value by default, unless you explicitly pass them by reference, as the following snippet shows:

$foo = array(11, 22, 33);

function hello($fooarg) {
  $fooarg[0] = 99;
}

function world(&$fooarg) {
  $fooarg[0] = 66;
}

hello($foo);
var_dump($foo); // (original array not modified) array passed-by-value

world($foo);
var_dump($foo); // (original array modified) array passed-by-reference

Here is the output:

array(3) {
  [0]=>
  int(11)
  [1]=>
  int(22)
  [2]=>
  int(33)
}
array(3) {
  [0]=>
  int(66)
  [1]=>
  int(22)
  [2]=>
  int(33)
}

I did the following...

1. place your css file in the app/assets/stylesheets folder.
2. Add the stylesheet link <%= stylesheet_link_tag "filename" %> in your default layouts file (most likely application.html.erb)

I recommend this over using your public folder. You can also reference the stylesheet inline, such as in your index page.

Calendar.setTime()

It's often useful to look at the signature and description of API methods, not just their name :) - Even in the Java standard API, names can sometimes be misleading.

Try this :

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.example.yourpackagename"
    minSdkVersion 15
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

you can get a files modified date using vbscript too

Set objFS=CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
strFile= objArgs(0)
WScript.Echo objFS.GetFile(strFile).DateLastModified

save the above as mygetdate.vbs and on command line

c:\test> cscript //nologo mygetdate.vbs myfile

Check for a directory 'apps/autocomplete/.svn'. Move it somewhere safe (in case you need to restore it because this did not work) and see if that fixes the problem.

I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:

xmlns:android="http://schemas.android.com/apk/res/android"

could also call it like that:

xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"

This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.

Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.

Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.

SQL tables are not ordered by default, and asking for the n-th row from a non ordered set of rows has no meaning as it could potentially return a different row each time unless you specify an ORDER BY:

select * from customer order by id where row_number() = 3

(sometimes MySQL tables are shown with an internal order but you cannot rely on this behaviour). Then you can use LIMIT offset, row_count, with a 0-based offset so row number 3 becomes offset 2:

select * from customer order by id
limit 2, 1

or you can use LIMIT row_count OFFSET offset:

select * from customer order by id
limit 1 offset 2

I've achieved the same thing before by using subqueries. So if your original table was called StoreCountsByWeek, and you had a separate table that listed the Store IDs, then it would look like this:

SELECT StoreID, 
    Week1=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=1),
    Week2=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=2),
    Week3=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=3)
FROM Store
ORDER BY StoreID

One advantage to this method is that the syntax is more clear and it makes it easier to join to other tables to pull other fields into the results too.

My anecdotal results are that running this query over a couple of thousand rows completed in less than one second, and I actually had 7 subqueries. But as noted in the comments, it is more computationally expensive to do it this way, so be careful about using this method if you expect it to run on large amounts of data .

Overall:You persist entity that is violating database rules like as saving entity that has varchar field over 250 chars ,something like that.

In my case it was a squishy problem with TestEntityManager ,because it use HSQL database /in memory database/ and it persist the user but when you try to find it ,it drops the same exception :/

@RunWith(SpringRunner.class)
@ContextConfiguration(classes= Application.class)
@DataJpaTest
@ActiveProfiles("test")
public class UserServicesTests {

@Autowired
private TestEntityManager testEntityManager;

@Autowired
private UserRepository userRepository;

@Test
public void oops() {
    User user = new User();
    user.setUsername("Toshko");
    //EMAIL IS REQUIRED:
    //user.setEmail("OPS");
    this.testEntityManager.persist(user);

    //HERE COMES TE EXCEPTION BECAUSE THE EMAIL FIELD IN TE DATABASE IS REQUIRED :
    this.userRepository.findUserByUsername("Toshko");

    System.out.println();
}
}

You can either write in the new lines separately or within a single string, which is easier.

Example 1

Input

line1 = "hello how are you"
line2 = "I am testing the new line escape sequence"
line3 = "this seems to work"

You can write the '\n' separately:

file.write(line1)
file.write("\n")
file.write(line2)
file.write("\n")
file.write(line3)
file.write("\n")

Output

hello how are you
I am testing the new line escape sequence
this seems to work

Example 2

Input

As others have pointed out in the previous answers, place the \n at the relevant points in your string:

line = "hello how are you\nI am testing the new line escape sequence\nthis seems to work"

file.write(line)

Output

hello how are you
I am testing the new line escape sequence
this seems to work

"+" does not mutate the list

.append() mutates the old list

Following worked for me.

SELECT *
FROM table_log
WHERE DATE(start_time) <= '2017-01-09' AND DATE(start_time) >= '2016-12-21'

Was playing with this today... I beleive you can also use @@ROWCOUNT, like this:

DECLARE @SQL VARCHAR(50)
DECLARE @Rowcount INT
SET @SQL = 'SELECT 1 UNION SELECT 2'
EXEC(@SQL)
SET @Rowcount = @@ROWCOUNT
SELECT @Rowcount

Then replace the 'SELECT 1 UNION SELECT 2' with your actual select without the count. I'd suggest just putting 1 in your select, like this:

SELECT 1
FROM dbo.Comm_Services
WHERE....
....

(as opposed to putting SELECT *)

Hope that helps.

You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.

For your purpose, it would make most sense to define a custom filter, so you could for example do the following:

The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{  splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{  splitpart(1) }}

The filter function could then look like this:

def splitpart (value, index, char = ','):
    return value.split(char)[index]

An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.

In .NET, I recommend to dynamically build the regular expression with the decimal separator of the current cultural context:

using System.Globalization;

...

NumberFormatInfo nfi = NumberFormatInfo.CurrentInfo;
Regex re = new Regex("^(?\\d+(" 
                   + Regex.Escape(nfi.CurrencyDecimalSeparator) 
                   + "\\d{1,2}))$");

You might want to pimp the regexp by allowing 1000er separators the same way as the decimal separator.

I tried all the above solutions.I came up solving the issue.Here I am posting the full solution.

The xml file:

<RelativeLayout
    android:id="@+id/header_main_page_clist1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="20dp"
    android:paddingBottom="10dp"
    android:background="#ffffff" >

    <ListView
        android:id="@+id/lv_msglist"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="@color/divider_color"
        android:dividerHeight="1dp" />

    <TextView
        android:id="@+id/emptyElement"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="NO MESSAGES AVAILABLE!"
        android:textColor="#525252"
        android:textSize="19.0sp"
        android:visibility="gone" />
</RelativeLayout>

The textView ("@+id/emptyElement") is the placeholder for the empty listview.

Here is the code for java page:

lvmessage=(ListView)findViewById(R.id.lv_msglist);
lvmessage.setAdapter(adapter);
lvmessage.setEmptyView(findViewById(R.id.emptyElement));

Remember to place the emptyView after binding the adapter to listview.Mine was not working for first time and after I moved the setEmptyView after the setAdapter it is now working.

Output:

== is the correct operator to compare strings in Go. However, the strings that you read from STDIN with reader.ReadString do not contain "a", but "a\n" (if you look closely, you'll see the extra line break in your example output).

You can use the strings.TrimRight function to remove trailing whitespaces from your input:

if strings.TrimRight(input, "\n") == "a" {
    // ...
}

You can use \blacksquare ¦:

When creating TeX, Knuth provided the symbol ¦ (solid black square), also called by mathematicians tombstone or Halmos symbol (after Paul Halmos, who pioneered its use as an equivalent of Q.E.D.). The tombstone is sometimes open: ? (hollow black square).

here is my code..

const input = MobileNumberComponent.find('input')
// when
input.props().onChange({target: {
   id: 'mobile-no',
   value: '1234567900'
}});
MobileNumberComponent.update()
const Footer = (loginComponent.find('Footer'))
expect(Footer.find('Buttons').props().disabled).equals(false)

I have update my DOM with componentname.update() And then checking submit button validation(disable/enable) with length 10 digit.

You should not use su in a dockerfile, however you should use the USER instruction in the Dockerfile.

At each stage of the Dockerfile build, a new container is created so any change you make to the user will not persist on the next build stage.

For example:

RUN whoami
RUN su test
RUN whoami

This would never say the user would be test as a new container is spawned on the 2nd whoami. The output would be root on both (unless of course you run USER beforehand).

If however you do:

RUN whoami
USER test
RUN whoami

You should see root then test.

Alternatively you can run a command as a different user with sudo with something like

sudo -u test whoami

But it seems better to use the official supported instruction.

Use jQuery. Keep your checkbox elements hidden and create a list like this:

<ul id="list">
    <li><a href="javascript:void(0)" id="link1">Happy face</a></li>
    <li><a href="javascript:void(0)" id="link2">Sad face</a></li>
</ul>

<form action="file.php" method="post">
    <!-- More code -->
    <input type="radio" id="option1" name="radio1" value="happy" style="display:none"/>
    <input type="radio" id="option2" name="radio1" value="sad" style="display:none"/>
    <!-- More code -->
</form>

<script type="text/javascript">
$("#list li a").click(function() {
    $('#list .active').removeClass("active");
    var id = this.id;
    var newselect = id.replace('link', 'option');
    $('#'+newselect).attr('checked', true);
    $(this).addClass("active").parent().addClass("active");
    return false;
});
</script>

This code would add the checked attribute to your radio inputs in the background and assign class active to your list elements. Do not use inline styles of course, don't forget to include jQuery and everything should run out of the box after you customize it.

Cheers!

For Typescript 2.x.x you should do it in a following way(using type guard):

tl;dr

function isDefined<T>(value: T | undefined | null): value is T {
  return <T>value !== undefined && <T>value !== null;
}

Why?

In this way isDefined() will respect variable's type and the following code would know take this check in account.

Example 1 - basic check:

function getFoo(foo: string): void { 
  //
}

function getBar(bar: string| undefined) {   
  getFoo(bar); //ERROR: "bar" can be undefined
  if (isDefined(bar)) {
    getFoo(bar); // Ok now, typescript knows that "bar' is defined
  }
}

Example 2 - types respect:

function getFoo(foo: string): void { 
  //
}

function getBar(bar: number | undefined) {
  getFoo(bar); // ERROR: "number | undefined" is not assignable to "string"
  if (isDefined(bar)) {
    getFoo(bar); // ERROR: "number" is not assignable to "string", but it's ok - we know it's number
  }
}

The question is simple: given a C++ array (e.g. x as in int x[10]), how would you get the number of elements in it?

An obvious solution is the following macro (definition 1):

#define countof( array ) ( sizeof( array )/sizeof( array[0] ) )

I cannot say this isn’t correct, because it does give the right answer when you give it an array. However, the same expression gives you something bogus when you supply something that is not an array. For example, if you have

int * p;

then countof( p ) always give you 1 on a machine where an int pointer and an int have the same size (e.g. on a Win32 platform).

This macro also wrongfully accepts any object of a class that has a member function operator[]. For example, suppose you write

class IntArray {
private:
    int * p;
    size_t size;
public:
    int & operator [] ( size_t i );
} x;

then sizeof( x ) will be the size of the x object, not the size of the buffer pointed to by x.p. Therefore you won’t get a correct answer by countof( x ).

So we conclude that definition 1 is not good because the compiler does not prevent you from misusing it. It fails to enforce that only an array can be passed in.

What is a better option?

Well, if we want the compiler to ensure that the parameter to countof is always an array, we have to find a context where only an array is allowed. The same context should reject any non-array expression.

Some beginners may try this (definition 2):

template <typename T, size_t N>
size_t countof( T array[N] )
{
   return N;
}

They figure, this template function will accept an array of N elements and return N.

Unfortunately, this doesn’t compile because C++ treats an array parameter the same as a pointer parameter, i.e. the above definition is equivalent to:

template <typename T, size_t N>
size_t countof( T * array )
{
    return N;
}

It now becomes obvious that the function body has no way of knowing what N is.

However, if a function expects an array reference, then the compiler does make sure that the size of the actual parameter matches the declaration. This means we can make definition 2 work with a minor modification (definition 3):

template <typename T, size_t N>
size_t countof( T (&array)[N] )
{
    return N;
}

This countof works very well and you cannot fool it by giving it a pointer. However, it is a function, not a macro. This means you cannot use it where a compile time constant is expected. In particular, you cannot write something like:

int x[10];

int y[ 2*countof(x) ]; // twice as big as x

Can we do anything about it?

Someone (I don’t know who it is – I just saw it in a piece of code from an unknown author) came up with a clever idea: moving N from the body of the function to the return type (e.g. make the function return an array of N elements), then we can get the value of N without actually calling the function.

To be precise, we have to make the function return an array reference, as C++ does not allow you to return an array directly.

The implementation of this is:

template <typename T, size_t N>
char ( &_ArraySizeHelper( T (&array)[N] ))[N];

#define countof( array ) (sizeof( _ArraySizeHelper( array ) ))

Admittedly, the syntax looks awful. Indeed, some explanation is necessary.

First, the top-level stuff

char ( &_ArraySizeHelper( ... ))[N];

says _ArraySizeHelper is a function that returns a reference (note the &) to a char array of N elements.

Next, the function parameter is

T (&array)[N]

which is a reference to a T array of N elements.

Finally, countof is defined as the size of the result of the function _ArraySizeHelper. Note we don’t even need to define _ArraySizeHelper(), -- a declaration is enough.

With this new definition,

int x[10];

int y[ 2*countof(x) ]; // twice as big as x

becomes valid, just as we desire.

Am I happy now? Well, I think this definition is definitely better than the others we have visited, but it is still not quite what I want. For one thing, it doesn’t work with types defined inside a function. That’s because the template function _ArraySizeHelper expects a type that is accessible in the global scope.

I don’t have a better solution. If you know one, please let me know.

I just catch this "EmptyResultDataAccessException"

public Myclass findOne(String id){
    try {
        Myclass m = this.jdbcTemplate.queryForObject(
                "SELECT * FROM tb_t WHERE id = ?",
                new Object[]{id},
                new RowMapper<Myclass>() {
                    public Myclass mapRow(ResultSet rs, int rowNum) throws SQLException {
                        Myclass m = new Myclass();
                        m.setName(rs.getString("name"));
                        return m;
                    }
                });
        return m;
    } catch (EmptyResultDataAccessException e) { // result.size() == 0;
        return null;
    }
}

then you can check:

if(m == null){
    // insert operation.
}else{
    // update operation.
}

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

If is about localizing thousands separators, delimiters and decimal separators, go with the following:

// --> numObj.toLocaleString( [locales [, options] ] )
parseInt( number ).toLocaleString();

There are several options you can use (and even locales with fallbacks):

number = 123456.7089;_x000D_
_x000D_
result  = parseInt( number ).toLocaleString() + "<br>";_x000D_
result += number.toLocaleString( 'de-DE' ) + "<br>";_x000D_
result += number.toLocaleString( 'ar-EG' ) + "<br>";_x000D_
result += number.toLocaleString( 'ja-JP', { _x000D_
  style           : 'currency',_x000D_
  currency        : 'JPY',_x000D_
  currencyDisplay : 'symbol',_x000D_
  useGrouping     : true_x000D_
} ) + "<br>";_x000D_
result += number.toLocaleString( [ 'jav', 'en' ], { _x000D_
  localeMatcher            : 'lookup',_x000D_
  style                    : 'decimal',_x000D_

} ) + "<br>";_x000D_
_x000D_
var el = document.getElementById( 'result' );_x000D_
el.innerHTML = result;

<div id="result"></div>

Edit: Commentor @I like Serena adds the following:

To support browsers with a non-English locale where we still want English formatting, use value.toLocaleString('en'). Also works for floating point.

For what it's worth, a shorter way to write code to check each command for success is:

command1 || echo "command1 borked it"
command2 || echo "command2 borked it"

It's still tedious but at least it's readable.

Here is a simple and backward compatible way to deliver ripple effect to raised buttons with the custom background.

Your layout should look like this

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/my_custom_background"
    android:foreground="?android:attr/selectableItemBackground"/>

You can use the short version:

File.write('/path/to/file', 'Some glorious content')

It returns the length written; see ::write for more details and options.

To append to the file, if it already exists, use:

File.write('/path/to/file', 'Some glorious content', mode: 'a')

using "&"

As you have noticed executing the bat directly without CALL,START, CMD /C causes to enter and execute the first file and then the process to stop as the first file is finished. Though you still can use & which will be the same as using command1 & command2 directly in the console:

(
    first.bat
)&(
    second.bat
)& (
    third.bat
)&(
    echo other commands
)

In a term of machine resources this will be the most efficient way though in the last block you won't be able to use command line GOTO,SHIFT,SETLOCAL.. and its capabilities will almost the same as in executing commands in the command prompt. And you won't be able to execute other command after the last closing bracket

Using CALL

call first.bat
call second.bat
call third.bat

In most of the cases it will be best approach - it does not create a separate process but has almost identical behaviour as calling a :label as subroutine. In MS terminology it creates a new "batch file context and pass control to the statement after the specified label. The first time the end of the batch file is encountered (that is, after jumping to the label), control returns to the statement after the call statement."

You can use variables set in the called files (if they are not set in a SETLOCAL block), you can access directly labels in the called file.

CMD /C, Pipes ,FOR /F

Other native option is to use CMD /C (the /C switch will force the called console to exit and return the control) Something that cmd.exe is doing in non transparent way with using FOR /F against bat file or when pipes are used. This will spawn a child process that will have all the environment ot the calling bat. Less efficient in terms of resources but as the process is separate ,parsing crashes or calling an EXIT command will not stop the calling .bat

@echo off
CMD /c first.bat
CMD /C second.bat

::not so different than the above lines.
:: MORE,FINDSTR,FIND command will be able to read the piped data 
:: passed from the left side

break|third.bat

START

Allows you more flexibility as the capability to start the scripts in separate window , to not wait them to finish, setting a title and so on. By default it starts the .bat and .cmd scripts with CMD /K which means that the spawned scripts will not close automatically.Again passes all the environment to the started scripts and consumes more resources than cmd /c:

:: will be executed in the same console window and will wait to finish
start "" /b /w cmd /c first.bat 

::will start in a separate console window and WONT wait to be finished
:: the second console window wont close automatically so second.bat might need explicit exit command
start "" second.bat

::Will start it in a separate window ,but will wait to finish
:: closing the second window will cause Y/N prompt
:: in the original window 
start "" /w third.cmd


::will start it in the same console window
:: but wont wait to finish. May lead to a little bit confusing output
start "" /b cmd /c fourth.bat

WMIC

Unlike the other methods from now on the examples will use external of the CMD.exe utilities (still available on Windows by default). WMIC utility will create completely separate process so you wont be able directly to wait to finish. Though the best feature of WMIC is that it returns the id of the spawned process:

:: will create a separate process with cmd.exe /c
WMIC process call create "%cd%\first.bat","%cd%"

::you can get the PID and monitoring it with other tools
for /f "tokens=2 delims=;= " %%# in ('WMIC process call create "%cd%\second.bat"^,"%cd%" ^|find "ProcessId"') do (
    set "PID=%%#"
)
echo %PID%

You can also use it to start a process on a remote machine , with different user and so on.

SCHTASKS

Using SCHTASKS provides some features as (obvious) scheduling , running as another user (even the system user) , remote machine start and so on. Again starts it in completely separate environment (i.e. its own variables) and even a hidden process, xml file with command parameters and so on :

SCHTASKS /create /tn BatRunner /tr "%cd%\first.bat" /sc ONCE /sd 01/01/1910 /st 00:00
SCHTASKS /Run /TN BatRunner
SCHTASKS /Delete /TN BatRunner /F

Here the PID also can acquired from the event log.

ScriptRunner

Offers some timeout between started scripts. Basic transaction capabilities (i.e. rollback on error) and the parameters can be put in a separate XML file.

::if the script is not finished after 15 seconds (i.e. ends with pause) it will be killed
ScriptRunner.exe -appvscript %cd%\first.bat -appvscriptrunnerparameters -wait -timeout=15


::will wait or the first called script before to start the second
:: if any of the scripts exit with errorcode different than 0 will try
:: try to restore the system in the original state
ScriptRunner.exe -appvscript second.cmd arg1 arg2 -appvscriptrunnerparameters -wait -rollbackonerror -appvscript third.bat -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror

I would recommend using Properties.Settings to store values like ConnectionStrings and so on inside of the class library. This is where all the connection strings are stores in by suggestion from visual studio when you try to add a table adapter for example. enter image description here

And then they will be accessible by using this code every where in the clas library

var cs=  Properties.Settings.Default.[<name of defined setting>];

Here comes a solution with XSLT:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//element3">
    <xsl:value-of select="element4/text()" />.<xsl:value-of select="element5/text()" />
</xsl:template>
</xsl:stylesheet>

You need to tell it that you are using SSL:

props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

In case you miss anything, here is working code:

String  d_email = "[email protected]",
            d_uname = "Name",
            d_password = "urpassword",
            d_host = "smtp.gmail.com",
            d_port  = "465",
            m_to = "[email protected]",
            m_subject = "Indoors Readable File: " + params[0].getName(),
            m_text = "This message is from Indoor Positioning App. Required file(s) are attached.";
    Properties props = new Properties();
    props.put("mail.smtp.user", d_email);
    props.put("mail.smtp.host", d_host);
    props.put("mail.smtp.port", d_port);
    props.put("mail.smtp.starttls.enable","true");
    props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.socketFactory.port", d_port);
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");

    SMTPAuthenticator auth = new SMTPAuthenticator();
    Session session = Session.getInstance(props, auth);
    session.setDebug(true);

    MimeMessage msg = new MimeMessage(session);
    try {
        msg.setSubject(m_subject);
        msg.setFrom(new InternetAddress(d_email));
        msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));

Transport transport = session.getTransport("smtps");
            transport.connect(d_host, Integer.valueOf(d_port), d_uname, d_password);
            transport.sendMessage(msg, msg.getAllRecipients());
            transport.close();

        } catch (AddressException e) {
            e.printStackTrace();
            return false;
        } catch (MessagingException e) {
            e.printStackTrace();
            return false;
        }

Here is simplified tutorial:

Practical UML

For more I recommend to get some literature.

Important: HttpClientModule is for Angular 4.3.0 and above. Check @Maximus' comments and @Pengyy's answer for more info.

You need to inject HttpClient in your component/service not the module. If you import HttpClientModule in your @NgModule

// app.module.ts:
 
import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
 
// Import HttpClientModule from @angular/common/http
import {HttpClientModule} from '@angular/common/http';
 
@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module
    // after BrowserModule.
    HttpClientModule,
  ],
})
export class MyAppModule {}

So change

constructor(private httpClient: HttpModule) {}

to

constructor(private httpClient: HttpClient) {}

as it's been written in the documentation

However, since you imported the HttpModule

you need to inject constructor(private httpClient: Http) as @Maximus stated in the comments and @Pengyy in this answer.

And for more info on differences between HttpModule and HttpClientModule, check this answer

try this code it will make your input into upper case

edittext.setFilters(new InputFilter[] {new InputFilter.AllCaps()});

Style the td and th instead

td, th {
    border: 1px solid black;
}

And also to make it so there is no spacing between cells use:

table {
    border-collapse: collapse;
}

(also note, you have border-style: none; which should be border-style: solid;)

See an example here: http://jsfiddle.net/KbjNr/

That's right, each address needs to be quoted. If you have multiple addresses listed on the command line, the Send-MailMessage likes it if you specify both the human friendly and the email address parts.

Bootstrap has predefined classes that we use for styling. If you are familiar with CSS, you'd know what padding, margin and spacing etc. are.

mb-0 = margin-bottom:0;

OK now moving a little further in knowledge, bootstrap has more classes for margin including:

mt- = margin-top
mb- = margin-bottom
ml- = margin-left
mr- = margin-right
my- = it sets margin-left and margin-right at the same time on y axes
mX- = it sets margin-bottom and margin-top at the same time on X axes

This and much more is explained here https://getbootstrap.com/docs/5.0/utilities/spacing/ The best way to learn is through https://getbootstrap.com site itself. It explains a lot obout its built in classes.

Considering that you have

$replaced = array('1' => 'value1', '4' => 'value4');
$replacement = array('4' => 'value2', '6' => 'value3');

Doing $merge = $replacement + $replaced; will output:

Array('4' => 'value2', '6' => 'value3', '1' => 'value1');

The first array from sum will have values in the final output.

Doing $merge = $replaced + $replacement; will output:

Array('1' => 'value1', '4' => 'value4', '6' => 'value3');

this method works well for me

$('#td_id').attr('class','new class');

Maybe more simple;

var top  = window.pageYOffset || document.documentElement.scrollTop,
    left = window.pageXOffset || document.documentElement.scrollLeft;

The options object can be added to the chart when the new Chart object is created.

var chart1 = new Chart(canvas, {
    type: "pie",
    data: data,
    options: {
         legend: {
            display: false
         },
         tooltips: {
            enabled: false
         }
    }
});

What do I need to do to make this function wait for the result of the promise?

Use async/await (NOT Part of ECMA6, but available for Chrome, Edge, Firefox and Safari since end of 2017, see canIuse)
MDN

    async function waitForPromise() {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

Added due to comment: An async function always returns a Promise, and in TypeScript it would look like:

    async function waitForPromise(): Promise<string> {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

See here:

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html

Date and time input is accepted in almost any reasonable format, including ISO 8601, SQL-compatible, traditional POSTGRES, and others. For some formats, ordering of month, day, and year in date input is ambiguous and there is support for specifying the expected ordering of these fields.

In other words: just write anything and it will work.

Or check this table with all the unambiguous formats.

Haha, I have been stuck at that point a while ago as well, so I am glad I can help you out with a solution, that worked for me at least :)

What you want to do is define a new style within values/styles.xml so it looks like this

<resources>
    <style name = "AppTheme" parent = "android:Theme.Holo.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name = "NoActionBar" parent = "@android:style/Theme.Holo.Light">
        <item name = "android:windowActionBar">false</item>
        <item name = "android:windowNoTitle">true</item>
    </style>

</resources>

Only the NoActionBar style is intresting for you. At last you have to set is as your application's theme in the AndroidManifest.xml so it looks like this

<application
    android:allowBackup = "true"
    android:icon = "@drawable/ic_launcher"
    android:label = "@string/app_name"
    android:theme = "@style/NoActionBar"   <!--This is the important line-->
    >
    <activity
    [...]

I hope this helps, if not, let me know.

Can also be done like this:-

package main
import "fmt"     

func main(){
    var myname string
fmt.Scanf("%s", &myname)           
fmt.Println("Hello", myname)       
}

TL;DR

Line ending issue:

1. Change autocrlf setting to default true. I.e., checkout Windows-style line endings on Windows and commit Linux-style line endings on remote git repo:

   git config --global core.autocrlf true
   

2. On a Windows mahcine, change all files in the repo to Windows-style:

   unix2dos **
   

3. Git add all modified files and modified files will go:

   git add .
   git status
   

Background

• Platform: Windows, WSL

I occassionally run into this issue that git status shows I have files modified while git diff shows nothing. This is most likely issue of line endings. I finally figured out how it always happen and share here to see if it can help others.

Root Cause

The reason I encounter this issue often is that I work on a Windows machine and interact with Git in WSL. Switching between linux and Windows setting can easily cause this end-of-line issue. Since line ending format used in OS differs:

• Windows: \r\n
• OSX / Linux: \n

Common Practice

When you install Git on your machine, it will ask you to choose line endings setting. Usually, the common practice is to use (commit) Linux-style line endings on your remote git repo and checkout Windows-style on your Windows machine. If you use default setting, this is what git do for you.

This means if you have a shell script myScript.sh and bash script myScript.cmd in your repo, the scripts both exist with Linux-style ending in your remote git repo, and both exist with Windows-style ending on your Windows machine.

I used to checkout shell script file and use dos2unix to change the script line-ending in order to run the shell script in WSL. This is why I encounter the issue. Git keeps telling me my modification of line-ending has been changed and asks whether to commit the changes.

Solution

Use default line ending settings and if you change the line endings of some files (like use the dos2unix or dos2unix), drop the changings. If line-endings changes already exist and you would like to get rid of it, try git add them and the changes will go.

The nohup command is a signal masking utility and catches the hangup signal. Where as ampersand doesn’t catch the hang up signals. The shell will terminate the sub command with the hang up signal when running a command using & and exiting the shell. This can be prevented by using nohup, as it catches the signal. Nohup command accept hang up signal which can be sent to a process by the kernel and block them. Nohup command is helpful in when a user wants to start long running application log out or close the window in which the process was initiated. Either of these actions normally prompts the kernel to hang up on the application, but a nohup wrapper will allow the process to continue. Using the ampersand will run the command in a child process and this child of the current bash session. When you exit the session, all of the child processes of that process will be killed. The ampersand relates to job control for the active shell. This is useful for running a process in a session in the background.

Both state and props in react are used to control data into a component, generally props are set by parent and passed to child components and they are fixed throughout the component. For data that is going to change, we have to use state. And props are immutable while states are mutable, if you want to change props you can do from parent component and then pass it to child components.

I've found that the best (and easiest) way to delete leading, trailing (and excessive) spaces in Excel is to use a third-party plugin. I've been using ASAP Utilities for Excel and it accomplishes the task as well as adds many other much-needed features. This approach doesn't require writing formulas and can remove spaces on any selection spanning multiple columns and/or rows. I also use this to sanitize and remove the uninvited non-breaking space that often finds its way into Excel data when copying-and-pasting from other Microsoft products.

More information regarding ASAP Utilities and trimming can be found here:

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

If you want to search recursively, you can use this beautiful piece of code:

public static FileInfo GetNewestFile(DirectoryInfo directory) {
   return directory.GetFiles()
       .Union(directory.GetDirectories().Select(d => GetNewestFile(d)))
       .OrderByDescending(f => (f == null ? DateTime.MinValue : f.LastWriteTime))
       .FirstOrDefault();                        
}

Just call it the following way:

FileInfo newestFile = GetNewestFile(new DirectoryInfo(@"C:\directory\"));

and that's it. Returns a FileInfo instance or null if the directory is empty.

You want to check the result of scanf() to make sure there was a successful conversion; if there wasn't, then one of three things is true:

1. scanf() is choking on a character that isn't valid for the %f conversion specifier (i.e., something that isn't a digit, dot, 'e', or 'E');
2. scanf() has detected EOF;
3. scanf() has detected an error on reading stdin.

Example:

int moreData = 1;
...
printf("Input no: ");
fflush(stdout);
/**
 * Loop while moreData is true
 */
while (moreData)
{
  errno = 0;
  int itemsRead = scanf("%f", &input);
  if (itemsRead == 1)
  {
    printf("Output: %f\n", input);
    printf("Input no: ");
    fflush(stdout);
  }
  else
  {
    if (feof(stdin))
    {
      printf("Hit EOF on stdin; exiting\n");
      moreData = 0;
    }
    else if (ferror(stdin))
    {
      /**
       * I *think* scanf() sets errno; if not, replace
       * the line below with a regular printf() and
       * a generic "read error" message.
       */
      perror("error during read");
      moreData = 0;
    }
    else
    {
      printf("Bad character stuck in input stream; clearing to end of line\n");
      while (getchar() != '\n')
        ; /* empty loop */
      printf("Input no: ");
      fflush(stdout);
    }
 }

Today March 6, 2013, Microsoft released SQL Server Data Tools – Business Intelligence for Visual Studio 2012 (SSDT BI) templates. With SSDT BI for Visual Studio 2012 you can develop and deploy SQL Server Business intelligence projects. Projects created in Visual Studio 2010 can be opened in Visual Studio 2012 and the other way around without upgrading or downgrading – it just works.

The download/install is named to ensure you get the SSDT templates that contain the Business Intelligence projects. The setup for these tools is now available from the web and can be downloaded in multiple languages right here: http://www.microsoft.com/download/details.aspx?id=36843

No for the moment.

I doubt it will be possible for the future for ActiveX support will be discontinued in near future (as MS stated).

Look here about HTML Object tag, but not anything will be accepted. You should try.

Add a background-color to the element and you will nicely see the difference of inline vs. block, as explained by the other posters.

Just append below property in your query and the first header or line int the record will not load or it will be skipped.

Try this

tblproperties ("skip.header.line.count"="1");

echo array_search("car",array_keys($a));

in Firefox 39 I've found that setting a border to the select element will render the arrow as (2). No border set, will render the arrow as (1). I think it's a bug.

Little performance tip if somebody has a datastore kind of service with key -> value pairs:

If you have a service called dataStore, you can update a timestamp whenever your big data object changes. This way instead of deep watching the whole object, you are only watching a timestamp for change.

app.factory('dataStore', function () {

    var store = { data: [], change: [] };

    // when storing the data, updating the timestamp
    store.setData = function(key, data){
        store.data[key] = data;
        store.setChange(key);
    }

    // get the change to watch
    store.getChange = function(key){
        return store.change[key];
    }

    // set the change
    store.setChange = function(key){
        store.change[key] = new Date().getTime();
    }

});

And in a directive you are only watching the timestamp to change

app.directive("myDir", function ($scope, dataStore) {
    $scope.dataStore = dataStore;
    $scope.$watch('dataStore.getChange("myKey")', function(newVal, oldVal){
        if(newVal !== oldVal && newVal){
            // Data changed
        }
    });
});

When the jQuery click event calls your event handler, it sets "this" to the object that was clicked on. To turn it into a jQuery object, just pass it to the "$" function: $(this). So, to get, for example, the next sibling element, you would do this inside the click handler:

var nextSibling = $(this).next();

Edit: After reading Kevin's comment, I realized I might be mistaken about what you want. If you want to do what he asked, i.e. select the corresponding link in the other div, you could use $(this).index() to get the clicked link's position. Then you would select the link in the other div by its position, for example with the "eq" method.

var $clicked = $(this);
var linkIndex = $clicked.index();
$clicked.parent().next().children().eq(linkIndex);

If you want to be able to go both ways, you will need some way of determining which div you are in so you know if you need "next()" or "prev()" after "parent()"

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

Today powershell saved me.

For grep there is:

get-content somefile.txt | where { $_ -match "expression"}

or

select-string somefile.txt -pattern "expression"

and for sed there is:

get-content somefile.txt | %{$_ -replace "expression","replace"}

For more detail see Zain Naboulsis blog entry.

When testing around with code I sometimes missed out on deleting some syso s. So I made myself a template called syt.

System.out.println(${word_selection}${});//${todo}:remove${cursor}

Before I compile I always check my TODOs and will never forget to delete a System.out again.

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

The following example Web.config file will configure IIS to deny access for HTTP requests where the length of the "Content-type" header is greater than 100 bytes.

Check this one It's hacky, simple as that:

• Set -prefix-appearance to none to remove the styles
• Use text-indent to "push" the content a bit to the right
• Finally, set text-overflow to an empty string. Everything that extends beyond it's width will become... nothing! And that includes the arrow.

Now you're free to style it any way you want :)

.selectParent {_x000D_
  width: 80px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
.selectParent select {_x000D_
  text-indent: 1px;_x000D_
  text-overflow: '';_x000D_
  width: 100px;_x000D_
  -webkit-appearance: none;_x000D_
  -moz-appearance: none;_x000D_
  appearance: none;_x000D_
  padding: 2px 2px 2px 2px;_x000D_
  border: none;_x000D_
  background: transparent url("http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png") no-repeat 60px center;_x000D_
}

<div class="selectParent">_x000D_
  <select>_x000D_
    <option value="1">Option 1</option>_x000D_
    <option value="2">Option 2</option>_x000D_
  </select>_x000D_
</div>

View on JSFiddle

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

You can't make the div a link itself, but you can make an <a> tag act as a block, the same behaviour a <div> has.

a {
    display: block;
}

You can then set the width and height on it.

As a client-side developer I recommend to use blob URL, blob URL is a client-side URL which refers to a binary object

<video id="id" width="320" height="240"  type='video/mp4' controls  > </video>

in HTML leave your video src blank, and in JS fetch the video file using AJAX, make sure the response type is blob

window.onload = function() {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'mov_bbb.mp4', true);
    xhr.responseType = 'blob'; //important
    xhr.onload = function(e) {
        if (this.status == 200) {
            console.log("loaded");
            var blob = this.response;
            var video = document.getElementById('id');
            video.oncanplaythrough = function() {
                console.log("Can play through video without stopping");
                URL.revokeObjectURL(this.src);
            };
            video.src = URL.createObjectURL(blob);
            video.load();
        }
    };
    xhr.send();
}

Note: This method is not recommended for large file

EDIT

• Use cross-origin blocking for avoiding direct downloading

• if the video is delivered by an API Use different method (PUT/POST) instead of 'GET'

In pthread_exit, ret is an input parameter. You are simply passing the address of a variable to the function.

In pthread_join, ret is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL.

Long explanation:

In pthread_join, you get back the address passed to pthread_exit by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.

To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode. The appropriate converter is automatically configured.

    @PostMapping(value="/process")
    public void process(@RequestBody com.fasterxml.jackson.databind.JsonNode payload) {
        System.out.println(payload);
    }

I have found that the simplest way to do this is to set onClick for each button in the xml

<Button
android:id="@+id/vrHelp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/ic_menu_help"
android:onClick="helpB" />

and then you can do a switch case like this

  public void helpB(View v) {
    Button clickedButton = (Button) v;
    switch (clickedButton.getId()) {
      case R.id.vrHelp:
        dosomething...
        break;

      case R.id.coHelp:
        dosomething...
        break;

      case R.id.ksHelp:
        dosomething...
        break;

      case R.id.uHelp:
        dosomething...
        break;

      case R.id.pHelp:
        dosomething...
        break;
    }
  }

You need to understand the difference between classes and objects. From the Java tutorial:

An object is a software bundle of related state and behavior

A class is a blueprint or prototype from which objects are created

You've defined the prototypes but done nothing with them. To use an object, you need to create it. In Java, we use the new keyword.

new Date();

You will need to assign the object to a variable of the same type as the class the object was created from.

Date d = new Date();

Once you have a reference to the object you can interact with it

d.date("01", "12", "14");

The exception to this is static methods that belong to the class and are referenced through it

public class MyDate{
  public static date(){ ... }
}

...
MyDate.date();

In case you aren't aware, Java already has a class for representing dates, you probably don't want to create your own.

You can use string.Format("{0:c}", value).

• Currency Formatting in the .NET Framework

I use the term program to include applications (apps), utilities and even operating systems like windows, linux and mac OS. We kinda need an overall term for all the different terms available. It might be wrong but works for me. :)

This is a one line, SUPER easy to use:

$result = array();
array_walk_recursive($original_array,function($v) use (&$result){ $result[] = $v; });

It is very easy to understand, inside the anonymous function/closure. $v is the value of your $original_array.

You can use the old way:

public List magicalListGetter() {
    List list = doMagicalVooDooHere();

    return list;
}

or you can use Object and the parent class of everything:

public List<Object> magicalListGetter() {
    List<Object> list = doMagicalVooDooHere();

    return list;
}

Note Perhaps there is a better parent class for all the objects you will put in the list. For example, Number would allow you to put Double and Integer in there.

HTML :

<div id="myDiv">
    <form id="myForm">
    </form> 
</div>

jQuery :

var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';

$("#myDiv form#myForm").html(chbx);

//to insert dynamically created form 
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");

Demo

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

As of version 0.8.6 of Android Studio generating an APK file (signed and I believe unsigned, too) will be placed inside ProjectName/device/build/outputs/apk

For example, I am making something for Google Glass and my signed APK gets dropped in /Users/MyName/AndroidStudioProjects/HelloGlass/glass/build/outputs/apk

I'm using fileupload-jquery in haml. The original js is below:

At first I used the :cdata to convert (from html2haml), it doesn't work properly (Delete button can't remove relevant component in callback).

<script id='template-download' type='text/x-tmpl'>_x000D_

So I use :plain filter:

%script#template-download{:type => "text/x-tmpl"}_x000D_
  :plain_x000D_
    {% for (var i=0, file; file=o.files[i]; i++) { %}_x000D_

    </td>_x000D_
    </tr>_x000D_
    {% } %}

The converted result is exactly the same as the original.

So :plain filter in this senario fits my need.

:plain Does not parse the filtered text. This is useful for large blocks of text without HTML tags, when you don’t want lines starting with . or - to be parsed.

You can manage your application versioning wisely by using the Advanced Build Version Plugin for Gradle.

You just need to include the plugin in yout build.gradle:

buildscript {
  repositories {
      jcenter()
  }

  dependencies {
      classpath 'org.moallemi.gradle.advanced-build-version:gradle-plugin:1.5.0'
  }
}

apply plugin: 'org.moallemi.advanced-build-version'

And then you can use the versioning functions (and, obviously, customize them):

advancedVersioning {
    nameOptions { }
    codeOptions { }
    outputOptions { }
}

def appVersionName = advancedVersioning.versionName
def appVersionCode = advancedVersioning.versionCode

For more information, take a look at the official documentation.

In my case I faced this issue in my simulator because my computer's date was behind of current date. So do check this case too when you face SSL error.

In Netbeans please delete current you create the jar file and on the project explore of Netbeans please clean and build 2 or 3 times and right the project folder in project explore and build the jar file.

[Edit] There's another solution not mentioned yet, and it seems to outperform the others given so far in most cases.

Use string.translate to replace all valid characters in the string, and see if we have any invalid ones left over. This is pretty fast as it uses the underlying C function to do the work, with very little python bytecode involved.

Obviously performance isn't everything - going for the most readable solutions is probably the best approach when not in a performance critical codepath, but just to see how the solutions stack up, here's a performance comparison of all the methods proposed so far. check_trans is the one using the string.translate method.

Test code:

import string, re, timeit

pat = re.compile('[\w-]*$')
pat_inv = re.compile ('[^\w-]')
allowed_chars=string.ascii_letters + string.digits + '_-'
allowed_set = set(allowed_chars)
trans_table = string.maketrans('','')

def check_set_diff(s):
    return not set(s) - allowed_set

def check_set_all(s):
    return all(x in allowed_set for x in s)

def check_set_subset(s):
    return set(s).issubset(allowed_set)

def check_re_match(s):
    return pat.match(s)

def check_re_inverse(s): # Search for non-matching character.
    return not pat_inv.search(s)

def check_trans(s):
    return not s.translate(trans_table,allowed_chars)

The translate approach seems best in most cases, dramatically so with long valid strings, but is beaten out by regexes in test_long_invalid (Presumably because the regex can bail out immediately, but translate always has to scan the whole string). The set approaches are usually worst, beating regexes only for the empty string case.

Using all(x in allowed_set for x in s) performs well if it bails out early, but can be bad if it has to iterate through every character. isSubSet and set difference are comparable, and are consistently proportional to the length of the string regardless of the data.

There's a similar difference between the regex methods matching all valid characters and searching for invalid characters. Matching performs a little better when checking for a long, but fully valid string, but worse for invalid characters near the end of the string.

You can use both of ',' OR divide '/' symbols.
But, '/' is better.
Suppose the case of 'every 5 minutes'. If you use ',', you have to write the cron job as following:

0,5,10,15,20,25,30,35,....    *      *     *   * your_command

It means run your_command in every hour in all of defined minutes: 0,5,10,...

However, if you use '/', you can write the following simple and short job:

*/5  *  *  *  *  your_command

It means run your_command in the minutes that are dividable by 5 or in the simpler words, '0,5,10,...'

So, dividable symbol '/' is the best choice always;

I believe you are looking for the setTimeout function.

To make your code a little neater, define a separate function for onclick in a <script> block:

function myClick() {
  setTimeout(
    function() {
      document.getElementById('div1').style.display='none';
      document.getElementById('div2').style.display='none';
    }, 5000);
}

then call your function from onclick

onclick="myClick();"

there is a simple trick you can work here but it need preparation before you print, you have to put what ever you wants to print in a variable and then print so you will know the length to remove the string.here is an example.

#include <iostream>
#include <string> //actually this thing is not nessasory in tdm-gcc

using namespace  std;

int main(){

//create string variable

string str="Starting count";

//loop for printing numbers

    for(int i =0;i<=50000;i++){

        //get previous string length and clear it from screen with backspace charactor

        cout << string(str.length(),'\b');

        //create string line

        str="Starting count " +to_string(i);

        //print the new line in same spot

        cout <<str ;
    }

}

This should not be difficult. When creating a cell for your table, add a UITextField object to the cell's content view

UITextField *txtField = [[UITextField alloc] initWithFrame....]
...
[cell.contentView addSubview:txtField]

Set the delegate of the UITextField as self (ie your viewcontroller) Give a tag to the text field so you can identify which textfield was edited in your delegate methods. The keyboard should pop up when the user taps the text field. I got it working like this. Hope it helps.

Yes.

I created an extension method for moving items in a list.

An index should not shift if we are moving an existing item since we are moving an item to an existing index position in the list.

The edge case that @Oliver refers to below (moving an item to the end of the list) would actually cause the tests to fail, but this is by design. To insert a new item at the end of the list we would just call List<T>.Add. list.Move(predicate, list.Count) should fail since this index position does not exist before the move.

In any case, I've created two additional extension methods, MoveToEnd and MoveToBeginning, the source of which can be found here.

/// <summary>
/// Extension methods for <see cref="System.Collections.Generic.List{T}"/>
/// </summary>
public static class ListExtensions
{
    /// <summary>
    /// Moves the item matching the <paramref name="itemSelector"/> to the <paramref name="newIndex"/> in a list.
    /// </summary>
    public static void Move<T>(this List<T> list, Predicate<T> itemSelector, int newIndex)
    {
        Ensure.Argument.NotNull(list, "list");
        Ensure.Argument.NotNull(itemSelector, "itemSelector");
        Ensure.Argument.Is(newIndex >= 0, "New index must be greater than or equal to zero.");

        var currentIndex = list.FindIndex(itemSelector);
        Ensure.That<ArgumentException>(currentIndex >= 0, "No item was found that matches the specified selector.");

        // Copy the current item
        var item = list[currentIndex];

        // Remove the item
        list.RemoveAt(currentIndex);

        // Finally add the item at the new index
        list.Insert(newIndex, item);
    }
}

http://rreddy.blogspot.com/2009/07/vncviewer-clipboard-operations-like.html

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.

To get those clipboard operations back you need to run the program "vncconfig &".

After this your clipboard actions should work fine with out any problems.

Run "vncconfig &" on the client.

Unfortunately the only reliable way i have found to check this cross browser is to poll the input. To make it responsive also listen to events. Chrome has started hiding auto fill values from javascript which needs a hack.

• Poll every half to third of a second ( Does not need to be instant in most cases )
• Trigger the change event using JQuery then do your logic in a function listening to the change event.

• Add a fix for Chrome hidden autofill password values.

  $(document).ready(function () {
      $('#inputID').change(YOURFUNCTIONNAME);
      $('#inputID').keypress(YOURFUNCTIONNAME);
      $('#inputID').keyup(YOURFUNCTIONNAME);
      $('#inputID').blur(YOURFUNCTIONNAME);
      $('#inputID').focusin(YOURFUNCTIONNAME);
      $('#inputID').focusout(YOURFUNCTIONNAME);
      $('#inputID').on('input', YOURFUNCTIONNAME);
      $('#inputID').on('textInput', YOURFUNCTIONNAME);
      $('#inputID').on('reset', YOURFUNCTIONNAME);
  
      window.setInterval(function() {
          var hasValue = $("#inputID").val().length > 0;//Normal
          if(!hasValue){
              hasValue = $("#inputID:-webkit-autofill").length > 0;//Chrome
          }
  
          if (hasValue) {
              $('#inputID').trigger('change');
          }
      }, 333);
  });
  

In the 1st, 2nd, and 3rd Edition of ECMAScript, using $-prefixed variable names was explicitly discouraged by the spec except in the context of autogenerated code:

The dollar sign ($) and the underscore (_) are permitted anywhere in an identifier. The dollar sign is intended for use only in mechanically generated code.

However, in the next version (the 5th Edition, which is current), this restriction was dropped, and the above passage replaced with

The dollar sign ($) and the underscore (_) are permitted anywhere in an IdentifierName.

As such, the $ sign may now be used freely in variable names. Certain frameworks and libraries have their own conventions on the meaning of the symbol, noted in other answers here.
