The documentation on counting says that for group_by queries it is better to use func.count():

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

if __name__ == '__main__':
    Example().main()

But you really shouldn't be using a class just to run your main code.

While the question is just a bit old, this might still help. I'm running into similar issues and using the option below has helped me. Not sure if this is a permanent solution, but it's fixing it for now.

OPTION (OPTIMIZE FOR UNKNOWN)

Then your query will be like this

select * from Table where Col = 'someval' OPTION (OPTIMIZE FOR UNKNOWN)

Codeigniter generates an "IS NULL" query by just leaving the call with no parameters:

$this->db->where('column');

The generated query is:

WHERE `column` IS NULL

The best solution is to keep multiple Views in a Single View / View Group and then keep that one view in the SrcollView. ie.

Format -

<ScrollView> 
  <Another View>
       <RecyclerView>
       <TextView>
       <And Other Views>
  </Another View>
</ScrollView>

Eg.

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>


        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>
 </ScrollView>

Another Eg. of ScrollView with multiple Views

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:orientation="vertical"
            android:layout_weight="1">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/imageView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#FFFFFF"
                />

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingHorizontal="10dp"
                android:orientation="vertical">

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/CategoryItem"
                    android:textSize="20sp"
                    android:textColor="#000000"
                    />

                <TextView
                    android:textColor="#000000"
                    android:text="?1000"
                    android:textSize="18sp"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>
                <TextView
                    android:textColor="#000000"
                    android:text="so\nugh\nos\nghs\nrgh\n

                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

             </LinearLayout>

        </LinearLayout>

</ScrollView>

$@ is nearly the same as $*, both meaning "all command line arguments". They are often used to simply pass all arguments to another program (thus forming a wrapper around that other program).

The difference between the two syntaxes shows up when you have an argument with spaces in it (e.g.) and put $@ in double quotes:

wrappedProgram "$@"
# ^^^ this is correct and will hand over all arguments in the way
#     we received them, i. e. as several arguments, each of them
#     containing all the spaces and other uglinesses they have.
wrappedProgram "$*"
# ^^^ this will hand over exactly one argument, containing all
#     original arguments, separated by single spaces.
wrappedProgram $*
# ^^^ this will join all arguments by single spaces as well and
#     will then split the string as the shell does on the command
#     line, thus it will split an argument containing spaces into
#     several arguments.

Example: Calling

wrapper "one two    three" four five "six seven"

will result in:

"$@": wrappedProgram "one two    three" four five "six seven"
"$*": wrappedProgram "one two    three four five six seven"
                             ^^^^ These spaces are part of the first
                                  argument and are not changed.
$*:   wrappedProgram one two three four five six seven

1. Use Update.

Drawing from Van Nguyen's answer above, use update instead of save. This gives you access to the upsert option.

NOTE: This method overrides the entire document when found (From the docs)

var conditions = { name: 'borne' }   , update = { $inc: { visits: 1 }} , options = { multi: true };

Model.update(conditions, update, options, callback);

function callback (err, numAffected) {   // numAffected is the number of updated documents })

1.a. Use $set

If you want to update a selection of the document, but not the whole thing, you can use the $set method with update. (again, From the docs)... So, if you want to set...

var query = { name: 'borne' };  Model.update(query, ***{ name: 'jason borne' }***, options, callback)

Send it as...

Model.update(query, ***{ $set: { name: 'jason borne' }}***, options, callback)

This helps prevent accidentally overwriting all of your document(s) with { name: 'jason borne' }.

Source: Use NATURAL FULL JOIN to compare two tables in SQL by Lukas Eder

Clever approach of using NATURAL FULL JOIN to detect the same/different rows between two tables.

Example 1 - status flag:

SELECT t1.*, t2.*, CASE WHEN t1 IS NULL OR t2 IS NULL THEN 'Not equal' ELSE 'Equal' END
FROM t1
NATURAL FULL JOIN t2;

Example 2 - filtering rows

SELECT *
FROM (SELECT 't1' AS t1, t1.* FROM t1) t1 
NATURAL FULL JOIN (SELECT 't2' AS t2, t2.* FROM t2) t2 
WHERE t1 IS NULL OR t2 IS NULL -- show differences
--WHERE  t1 IS NOT NULL AND t2 IS NOT NULL    -- show the same

db<>fiddle demo

try this:

ComboBox cbx = new ComboBox();
cbx.DisplayMember = "Text";
cbx.ValueMember = "Value";

EDIT (a little explanation, sory, I also didn't notice your combobox wasn't bound, I blame the lack of caffeine):

The difference between SelectedValue and SelectedItem are explained pretty well here: ComboBox SelectedItem vs SelectedValue

So, if your combobox is not bound to datasource, DisplayMember and ValueMember doesn't do anything, and SelectedValue will always be null, SelectedValueChanged won't be called. So either bind your combobox:

            comboBox1.DisplayMember = "Text";
            comboBox1.ValueMember = "Value";

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

            ComboboxItem item = new ComboboxItem();
            item.Text = "choose a server...";
            item.Value = "-1";
            list.Add(item);

            item = new ComboboxItem();
            item.Text = "S1";
            item.Value = "1";
            list.Add(item);

            item = new ComboboxItem();
            item.Text = "S2";
            item.Value = "2";
            list.Add(item);

            cbx.DataSource = list; // bind combobox to a datasource

or use SelectedItem property:

if (cbx.SelectedItem != null)
             Console.WriteLine("ITEM: "+comboBox1.SelectedItem.ToString());

try this

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            Image = Image.FromFile(@"c:\Images\test.jpg"),
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Remove the API key parameter and its value.

eg. https://maps.googleapis.com/maps/api/geocode/json?address=[YOUR ADDRESS]&sensor=true

I just did the same. If you look in the "Android SDK Manager" in the "Android 4.0 (API 14)" section you'll see a few packages. One of these is named "ARM EABI v7a System Image".

This is what you need to download in order to create an Android 4.0 virtual device:

The classic way would be to add commas to the left and right:

select * from shirts where CONCAT(',', colors, ',') like '%,1,%'

But find_in_set also works:

select * from shirts where find_in_set('1',colors) <> 0

This works for me:

git pull origin <sha>

e.g.

[dbn src]$ git fetch
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 7 different commits each, respectively.
...
[dbn src]$ git log -3 --pretty=oneline origin/master
f4d10ad2a5eda447bea53fed0b421106dbecea66 CASE-ID1: some descriptive msg
28eb00a42e682e32bdc92e5753a4a9c315f62b42 CASE-ID2: I'm so good at writing commit titles
ff39e46b18a66b21bc1eed81a0974e5c7de6a3e5 CASE-ID2: woooooo
[dbn src]$ git pull origin 28eb00a42e682e32bdc92e5753a4a9c315f62b42
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 1 different commits each, respectively.
...

This pulls 28eb00, ff39e4, and everything before, but doesn't pull f4d10ad. It allows the use of pull --rebase, and honors pull settings in your gitconfig. This works because you're basically treating 28eb00 as a branch.

For the version of git that I'm using, this method requires a full commit hash - no abbreviations or aliases are allowed. You could do something like:

[dbn src]$ git pull origin `git rev-parse origin/master^`

This one did it for me. It works with a date and you can substract the wanted amount in years to go back in time:

@echo off

set m=%date:~-7,2%
set /A m
set dateYear=%date:~-4,4%
set /A dateYear -= 2
set DATE_DIR=%date:~-10,2%.%m%.%dateYear% 

forfiles /p "C:\your\path\here\" /s /m *.* /d -%DATE_DIR% /c "cmd /c del @path /F"

pause

the /F in the cmd /c del @path /F forces the specific file to be deleted in some the cases the file can be read-only.

the dateYear is the year Variable and there you can change the substract to your own needs

There is no VBA built in functionality for removing duplicates from an array, however you could use the next function:

Function RemoveDuplicates(MyArray As Variant) As Variant
    With CreateObject("scripting.dictionary")
        For Each item In MyArray
            c00 = .Item(item)
        Next
        sn = .keys ' the array .keys contains all unique keys
        MsgBox Join(.keys, vbLf) ' you can join the array into a string
        RemoveDuplicates = .keys ' return an array without duplicates
    End With
End Function

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

To find all the matching strings, use String's scan method.

str = "A 54mpl3 string w1th 7 numb3rs scatter36 ar0und"
str.scan(/\d+/)
#=> ["54", "3", "1", "7", "3", "36", "0"]

If you want, MatchData, which is the type of the object returned by the Regexp match method, use:

str.to_enum(:scan, /\d+/).map { Regexp.last_match }
#=> [#<MatchData "54">, #<MatchData "3">, #<MatchData "1">, #<MatchData "7">, #<MatchData "3">, #<MatchData "36">, #<MatchData "0">]

The benefit of using MatchData is that you can use methods like offset:

match_datas = str.to_enum(:scan, /\d+/).map { Regexp.last_match }
match_datas[0].offset(0)
#=> [2, 4]
match_datas[1].offset(0)
#=> [7, 8]

See these questions if you'd like to know more:

• "How do I get the match data for all occurrences of a Ruby regular expression in a string?"
• "Ruby regular expression matching enumerator with named capture support"
• "How to find out the starting point for each match in ruby"

Reading about special variables $&, $', $1, $2 in Ruby will be helpful too.

Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.

For i = 0 To d.Count - 1
    s = d.Items()(i)
    Debug.Print s
Next i()

KEYS works the same way

For i = 0 To d.Count - 1
    Debug.Print d.Keys()(i), d.Items()(i)
Next i

This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".

Debug.Print Split("A,B,C,D", ",")(2)

SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.

Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.

I had the same problem, but in c# 2012 I closed the "report data" and I couldn't find it and I finally found a solution to this issue.

This is my method:

VIEW >> TOOLBARS >> CUSTOMIZE >> COMMANDS ... select from the "Menu bar" .. VIEW.

OK now in the "Controls" find the "REPORT DATA", select it and MOVE it UP, close the menu. After that select a file.rdlc and click on the "View" ... OK Finally will be appeared "REPORT DATA"...

Use <property name="build.sysclasspath" value="last"/> in your build.xml file

For more details search includeAntRuntime in Ant javac

Other possible values could be found here

The syntax is wrong, it should instead be

svn merge <what(the range)> <from(your dev branch)> <to(trunk/trunk local copy)>

if you want to display date along with time when you export to Excel then you can use this

xlWorkSheet.Cells(nRow, 3).NumberFormat = "dd/mm/yy h:mm AM/PM"

I find this simpler to understand:

split :: Char -> String -> [String]
split c xs = case break (==c) xs of 
  (ls, "") -> [ls]
  (ls, x:rs) -> ls : split c rs

Use

oncopy="return false" onpaste="return false"

Email: <input type="textbox" id="email" oncopy="return false" onpaste="return false" ><br/>
Confirm Email:    <input type="textbox" id="confirmEmail" oncopy="return false" onpaste="return false">

If you are running Rails (its the default db in Rails) check the {RAILS_ROOT}/config/database.yml file and you will see something like:

database: db/development.sqlite3

This means that it will be in the {RAILS_ROOT}/db directory.

textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;

WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this:

using System.Windows.Media;

textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;

On windows I've tried different approaches - setting JAVA_HOME, JRE_HOME and extending the PATH to point to the desiered jre18 but nothing helped - disabling the JRE17 in the java control panel didn't helped either

What helped me out was to force eclipse to use the appropriate JRE in the eclipse.ini file e.g.

-vm C:\java\jdk1.8.0_111\jre\bin\javaw.exe

in the received page you can use:

parse_str($str, $array); var_dump($array);

I create various return types using enum. It doesn't defined automatically. That implementation look like factory pattern.

public  enum  SmartReturn {

    IntegerType, DoubleType;

    @SuppressWarnings("unchecked")
    public <T> T comeback(String value) {
        switch (this) {
            case IntegerType:
                return (T) Integer.valueOf(value);
            case DoubleType:
                return (T) Double.valueOf(value);
            default:
                return null;
        }
    }
}

Unit Test:

public class MultipleReturnTypeTest {

  @Test
  public void returnIntegerOrString() {
     Assert.assertTrue(SmartReturn.IntegerType.comeback("1") instanceof Integer);
     Assert.assertTrue(SmartReturn.DoubleType.comeback("1") instanceof Double);
  }

}

You can type sudo install (name of script) /usr/local/bin/(what you want to type to execute said script)

ex: sudo install quickcommit.sh /usr/local/bin/quickcommit enter password

now can run without .sh and in any directory

I had the same problem and was able to use the following:

// Load the directory as a resource
URL dir_url = ClassLoader.getSystemResource(dir_path);
// Turn the resource into a File object
File dir = new File(dir_url.toURI());
// List the directory
String files = dir.list()

If you don't need it to be human-readable/editable, the easiest solution is to just use pickle.

To write:

with open(the_filename, 'wb') as f:
    pickle.dump(my_list, f)

To read:

with open(the_filename, 'rb') as f:
    my_list = pickle.load(f)

If you do need them to be human-readable, we need more information.

If my_list is guaranteed to be a list of strings with no embedded newlines, just write them one per line:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write(s + '\n')

with open(the_filename, 'r') as f:
    my_list = [line.rstrip('\n') for line in f]

If they're Unicode strings rather than byte strings, you'll want to encode them. (Or, worse, if they're byte strings, but not necessarily in the same encoding as your system default.)

If they might have newlines, or non-printable characters, etc., you can use escaping or quoting. Python has a variety of different kinds of escaping built into the stdlib.

Let's use unicode-escape here to solve both of the above problems at once:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write((s + u'\n').encode('unicode-escape'))

with open(the_filename, 'r') as f:
    my_list = [line.decode('unicode-escape').rstrip(u'\n') for line in f]

You can also use the 3.x-style solution in 2.x, with either the codecs module or the io module:*

import io

with io.open(the_filename, 'w', encoding='unicode-escape') as f:
    f.writelines(line + u'\n' for line in my_list)

with open(the_filename, 'r') as f:
    my_list = [line.rstrip(u'\n') for line in f]

_{* TOOWTDI, so which is the one obvious way? It depends… For the short version: if you need to work with Python versions before 2.6, use codecs; if not, use io.}

One solution to this problem is to use the Handler.postDelayed() method. Some Google training materials suggest the same solution.

@Override
public void onClick(View v) {
    my_button.setBackgroundResource(R.drawable.icon);

    Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() {
         @Override 
         public void run() { 
              my_button.setBackgroundResource(R.drawable.defaultcard); 
         } 
    }, 2000); 
}

However, some have pointed out that the solution above causes a memory leak because it uses a non-static inner and anonymous class which implicitly holds a reference to its outer class, the activity. This is a problem when the activity context is garbage collected.

A more complex solution that avoids the memory leak subclasses the Handler and Runnable with static inner classes inside the activity since static inner classes do not hold an implicit reference to their outer class:

private static class MyHandler extends Handler {}
private final MyHandler mHandler = new MyHandler();

public static class MyRunnable implements Runnable {
    private final WeakReference<Activity> mActivity;

    public MyRunnable(Activity activity) {
        mActivity = new WeakReference<>(activity);
    }

    @Override
    public void run() {
        Activity activity = mActivity.get();
        if (activity != null) {
            Button btn = (Button) activity.findViewById(R.id.button);
            btn.setBackgroundResource(R.drawable.defaultcard);
        }
    }
}

private MyRunnable mRunnable = new MyRunnable(this);

public void onClick(View view) {
    my_button.setBackgroundResource(R.drawable.icon);

    // Execute the Runnable in 2 seconds
    mHandler.postDelayed(mRunnable, 2000);
}

Note that the Runnable uses a WeakReference to the Activity, which is necessary in a static class that needs access to the UI.

onClick="javascript:this.form.submit();">

this in div onclick don't have attribute form, you may try this.parentNode.submit() or document.forms[0].submit() will do

Also, onClick, should be onclick, some browsers don't work with onClick

this seems to work on our site, using your ideas and a little math based upon the left edge of wrapper div. It seems redundant to go left 50% then take out 50% extra margin, but it seems to work.

div.ImgWrapper {
    width: 160px;
    height: 160px
    overflow: hidden;
    text-align: center;
}

img.CropCenter {
    left: 50%;
    margin-left: -100%;
    position: relative;
    width: auto !important;
    height: 160px !important;
}

<div class="ImgWrapper">
<a href="#"><img class="CropCenter" src="img.png"></a>
</div>

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

You can use the VBA string functions (as @onedaywhen points out in the comments, they are not really the VBA functions, but their equivalents from the MS Jet libraries. As far as function signatures go, they are called and work the same, even though the actual presence of MS Access is not required for them to be available.):

SELECT DISTINCT Left(LastName, 1)
FROM Authors;

SELECT DISTINCT Mid(LastName, 1, 1)
FROM Authors;

Note: Ruby >= 1.9.2 has an order-preserving hash: the order keys are inserted will be the order they are enumerated. The below applies to older versions or to backward-compatible code.

There is no concept of a sorted hash. So no, what you're doing isn't right.

If you want it sorted for display, return a string:

"{" + h.sort.map{|k,v| "#{k.inspect}=>#{v.inspect}"}.join(", ") + "}"

or, if you want the keys in order:

h.keys.sort

or, if you want to access the elements in order:

h.sort.map do |key,value|
  # keys will arrive in order to this block, with their associated value.
end

but in summary, it makes no sense to talk about a sorted hash. From the docs, "The order in which you traverse a hash by either key or value may seem arbitrary, and will generally not be in the insertion order." So inserting keys in a specific order into the hash won't help.

Old Answer (July 2016):

You can't directly debug Chrome for iOS due to restrictions on the published WKWebView apps, but there are a few options already discussed in other SO threads:

1. If you can reproduce the issue in Safari as well, then use Remote Debugging with Safari Web Inspector. This would be the easiest approach.

2. WeInRe allows some simple debugging, using a simple client-server model. It's not fully featured, but it may well be enough for your problem. See instructions on set up here.

3. You could try and create a simple WKWebView browser app (some instructions here), or look for an existing one on GitHub. Since Chrome uses the same rendering engine, you could debug using that, as it will be close to what Chrome produces.

There's a "bug" opened up for WebKit: Allow Web Inspector usage for release builds of WKWebView. If and when we get an API to WKWebView, Chrome for iOS would be debuggable.

Update January 2018:

Since my answer back in 2016, some work has been done to improve things.

There is a recent project called RemoteDebug iOS WebKit Adapter, by some of the Microsoft team. It's an adapter that handles the API differences between Webkit Remote Debugging Protocol and Chrome Debugging Protocol, and this allows you to debug iOS WebViews in any app that supports the protocol - Chrome DevTools, VS Code etc.

Check out the getting started guide in the repo, which is quite detailed.

If you are interesting, you can read up on the background and architecture here.

You can use CSS white-space Property to achieve this.

white-space: nowrap

Another one is OxyPlot, which is an open-source cross-platform (WPF, Silverlight, WinForms, Mono) .Net plotting library.

Here is how I do it:

app.directive('example', function() {

    return function(scope, element, attrs) {
        angular.element(document).ready(function() {
                //MANIPULATE THE DOM
        });
    };

});

try this

mysql_query("
SELECT * FROM Drinks WHERE
    email='$Email'
    AND date='$Date_Today'
    OR date='$Date_Yesterday', '$Date_TwoDaysAgo', '$Date_ThreeDaysAgo', '$Date_FourDaysAgo', '$Date_FiveDaysAgo', '$Date_SixDaysAgo', '$Date_SevenDaysAgo'"     
   );

my be like this

 OR date='$Date_Yesterday' oR '$Date_TwoDaysAgo'.........

If (ds != null)

Should do the work for you!

1-make 1 shape for Button right click on drawable nd new drawable resource file . change Root element to shape and make your shape.

enter image description here

2-now make 1 copy from your shape and change name and change solid color. enter image description here

3-right click on drawable and new drawable resource file just set root element to selector.

go to file and set "state_pressed"

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

<item android:state_pressed="true"android:drawable="@drawable/YourShape1"/>
<item android:state_pressed="false" android:drawable="@drawable/YourShape2"/>

</selector>

4-the end go to xml layout and set your Button background "your selector"

(sorry for my english weak)

You can do this by following one of the solutions:

Using constructor @Autowired

This approach will construct the bean requiring some beans as constructor parameters. Within the constructor code you set the static field with the value got as parameter for constructor execution. Sample:

@Component
public class Boo {

    private static Foo foo;

    @Autowired
    public Boo(Foo foo) {
        Boo.foo = foo;
    }

    public static void randomMethod() {
         foo.doStuff();
    }
}

Using @PostConstruct to hand value over to static field

The idea here is to hand over a bean to a static field after bean is configured by spring.

@Component
public class Boo {

    private static Foo foo;
    @Autowired
    private Foo tFoo;

    @PostConstruct
    public void init() {
        Boo.foo = tFoo;
    }

    public static void randomMethod() {
         foo.doStuff();
    }
}

Try this command:

git ls-files 

This lists all of the files in the repository, including those that are only staged but not yet committed.

http://www.kernel.org/pub/software/scm/git/docs/git-ls-files.html

Place this dependency, and dont forget to select : Include dependencies with "provided" scope

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

You can use the following code :

<!DOCTYPE html>
<html>
    <body onLoad="triggerJS();">

    <script>
        function triggerJS(){
        location.replace("http://www.google.com");
        /*
        location.assign("New_WebSite_Url");
        //Use assign() instead of replace if you want to have the first page in the history (i.e if you want the user to be able to navigate back when New_WebSite_Url is loaded)
        */
        }
    </script>

    </body>
</html>

This is a simple way of doing it:

Calendar cal = Calendar.getInstance();
SimpleDateFormat dateOnly = new SimpleDateFormat("MM/dd/yyyy");
System.out.println(dateOnly.format(cal.getTime()));

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

The \s metacharacter matches whitespace characters.

To get listing of object properties/values:

1. In Firefox - Firebug:

   console.dir(<object>);
   

2. Standard JS to get object keys borrowed from Slashnick:

      var fGetKeys = function(obj){
         var keys = [];
         for(var key in obj){
            keys.push(key);
         }
         return keys;
      }
   
   // Example to call it:
   
      var arrKeys = fGetKeys(document);
   
      for (var i=0, n=arrKeys.length; i<n; i++){
         console.log(i+1 + " - " + arrKeys[i] + document[arrKeys[i]] + "\n");
      }
   

Edits:

1. <object> in the above is to be replaced with the variable reference to the object.
2. console.log() is to be used in the console, if you're unsure what that is, you can replace it with an alert()

If you can't use box-sizing (e.g. when you convert HTML to PDF using iText). Try this:

CSS

.input-wrapper { border: 1px solid #ccc; padding: 0 5px; min-height: 20px; } 
.input-wrapper input[type=text] { border: none; height: 20px; width: 100%; padding: 0; margin: 0; }

HTML

<div class="input-wrapper">
     <input type="text" value="" name="city"/>
</div>

Creating functions like isBoolean which contains oneliner typeof v === "boolean" seems very unhandy in long term. i am suprised that almost everyone suggest to create your own function. It seems to be same cancer as extending native prototypes.

• you need to recreate them in every project you are involved
• other developers might have different habits,, or need to check source of your function to see which impementation of check you use, to know what are weak points of your check
• you will be fruustrated when you will try to write one liner in console on site which doesn't belong to your project

just memoize typeof v === "boolean" and that's all. Add a template to your IDE to be able to put it by some three letter shortcut and be happy.

Here .persist() only will insert the record.If we use .merge() it will check is there any record exist with the current ID, If it exists, it will update otherwise it will insert a new record.

Background images on :before and :after elements should work. If you post an example I could probably tell you why it does not work in your case.

Here is an example: http://jsfiddle.net/namas/3/

You can specify the dimensions of the element in % by using background-size: 100% 100% (width / height), for example.

I use prop attribute for unchecked the checkbox when errors occur. You don't need to use remove property for unchecked your checkbox.

$('input#IDName').prop('checked', false);

It is working fine for me. Hope it will work for you also.

I have had this issue before, which I solved by nested if statements first checking for none type separately.

{% if object.some_bool == None %}Empty
{% else %}{% if not object.some_bool %}False{% else %}True{% endif %}{% endif %}

If you only want to test if its false, then just

{% if some_bool == None %}{% else %}{% if not some_bool %}False{% endif %}{% endif %}

EDIT: This seems to work.

{% if 0 == a|length %}Zero-length array{% else %}{% if a == None %}None type{% else %}{% if not a %}False type{% else %}True-type {% endif %}{% endif %}{% endif %}

Now zero-length arrays are recognized as such; None types as None types; falses as False; Trues as trues; strings/arrays above length 0 as true.

You could also include in the Context a variable false_list = [False,] and then do

{% if some_bool in false_list %}False {% endif %}

Go to following path Control Panel>>System and Security>>System>>Advance system settings>>Environment Variables then set the variable value of ANDROID_HOME set it like following "C:\Users\username\AppData\Local\Android\sdk" set the username as your pc name, then just restart your android studio. Then you can create your AVD again after that your error will be gone and it will start the virtual device.

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

A minor update to this: a sender should never set the Return-Path: header. There's no such thing as a Return-Path: header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From unless the local system needs some kind of quirky routing.

It's a common misunderstanding because users rarely see an email without a Return-Path: header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path: header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4

I just input some value that I knew was invalid and here is the output:

'whatToInput' is not a supported event for HtmlPanelGrid. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

So values you can pass to event are

• click
• dblclick
• keydown
• mousedown
• mousemove
• mouseover
• mouseup

I had this error and discovered the issue was because the name of the component was identical to the name of a prop.

import Control from '@/Control.vue';
export default {
    name: 'Question',
    components: {
        Control
    },
    props: ['Control', 'source'],

I was using file components. I changed the Control.vue to InputControl.vue and this warning disappeared.

value_counts work only for series. It won't work for entire DataFrame. Try selecting only one column and using this attribute. For example:

df['accepted'].value_counts()

It also won't work if you have duplicate columns. This is because when you select a particular column, it will also represent the duplicate column and will return dataframe instead of series. At that time remove duplicate column by using

df = df.loc[:,~df.columns.duplicated()]
df['accepted'].value_counts()

private doesn't seem to work if you are defining a method on an explicit object (in your case self). You can use private_class_method to define class methods as private (or like you described).

class Person
  def self.get_name
    persons_name
  end

  def self.persons_name
    "Sam"
  end

  private_class_method :persons_name
end

puts "Hey, " + Person.get_name
puts "Hey, " + Person.persons_name

Alternatively (in ruby 2.1+), since a method definition returns a symbol of the method name, you can also use this as follows:

class Person
  def self.get_name
    persons_name
  end

  private_class_method def self.persons_name
    "Sam"
  end
end

puts "Hey, " + Person.get_name
puts "Hey, " + Person.persons_name

Yes, it is possible as follows. These colours can be used in a console application to view some errors in red, etc.

Console.BackgroundColor = ConsoleColor.Blue;
Console.ForegroundColor = ConsoleColor.White;//after this line every text will be white on blue background
Console.WriteLine("White on blue.");
Console.WriteLine("Another line.");
Console.ResetColor();//reset to the defoult colour

The consequence of this is that you may need a rather insane-looking query, e. g.,

SELECT [dbo].[tblTimeSheetExportFiles].[lngRecordID]            AS lngRecordID
          ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]  AS vcrSourceWorkbookName
          ,[dbo].[tblTimeSheetExportFiles].[vcrImportFileName]      AS vcrImportFileName
          ,[dbo].[tblTimeSheetExportFiles].[dtmLastWriteTime]       AS dtmLastWriteTime
          ,[dbo].[tblTimeSheetExportFiles].[lngNRecords]            AS lngNRecords

          ,SUM ( [tblTimeRecords].[decMan_Hours_Actual] )           AS decHoursWorked
          ,SUM ( [tblTimeRecords].[decAdjusted_Hours] )             AS decHoursBilled
      FROM [dbo].[tblTimeSheetExportFiles]
      LEFT JOIN   [dbo].[tblTimeRecords]
              ON  [dbo].[tblTimeSheetExportFiles].[lngRecordID] = [dbo].[tblTimeRecords].[lngTimeSheetExportFile]
        GROUP BY  [dbo].[tblTimeSheetExportFiles].[lngRecordID]
                 ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]
                 ,[dbo].[tblTimeSheetExportFiles].[vcrImportFileName]
                 ,[dbo].[tblTimeSheetExportFiles].[dtmLastWriteTime]
                 ,[dbo].[tblTimeSheetExportFiles].[lngNRecords]

Since the primary table is a summary table, its primary key handles the only grouping or ordering that is truly necessary. Hence, the GROUP BY clause exists solely to satisfy the query parser.

unless you have an explicit reason to choose the Apache HttpClient, you should prefer java.net.URLConnection. you can find plenty of examples of how to use it on the web.

we've also improved the Android documentation since your original post: http://developer.android.com/reference/java/net/HttpURLConnection.html

and we've talked about the trade-offs on the official blog: http://android-developers.blogspot.com/2011/09/androids-http-clients.html

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :

public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
    var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

    if (!string.IsNullOrEmpty(displayFormat) && value != null)
    {
        DateTime date;
        displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
        // use the format specified in the DisplayFormat attribute to parse the date
         if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
        {
            return date;
        }
        else
        {
            bindingContext.ModelState.AddModelError(
                bindingContext.ModelName,
                string.Format("{0} is an invalid date format", value.AttemptedValue)
            );
        }
    }

    return base.BindModel(controllerContext, bindingContext);
}

Hope this could help someone else...

It worked with ASP.NET only after adding the pragma:no-cache header in IIS. Cache-Control: no-cache was not enough.

Send a SIGTERM or a SIGKILL to it:

http://en.wikipedia.org/wiki/SIGKILL

http://en.wikipedia.org/wiki/SIGTERM

SIGTERM is polite and lets the process clean up before it goes, whereas, SIGKILL is for when it won't listen >:)

Example from the shell (man page: http://unixhelp.ed.ac.uk/CGI/man-cgi?kill )

kill -9 pid

In C, you can do the same thing using the kill syscall:

kill(pid, SIGKILL);

See the following man page: http://linux.die.net/man/2/kill

You can use label instead of textblock.

<Label Content="Hello, World!">
    <Label.LayoutTransform>
        <RotateTransform Angle="270"/>
    </Label.LayoutTransform>
</Label>

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

You should form the command with the contents of the textboxes:

sql = "insert into Main (Firt Name, Last Name) values(" + textbox2.Text + "," + textbox3.Text+ ")";

This, of course, provided that you manage to open the connection correctly.

It would be helpful to know what's happening with your current code. If you are getting some error displayed in that message box, it would be great to know what it's saying.

You should also validate the inputs before actually running the command (i.e. make sure they don't contain malicious code...).

Forget about finding a IDE to write/run/compile assembler on Mac. But, remember mac is UNIX. See http://asm.sourceforge.net/articles/linasm.html. A decent guide (though short) to running assembler via GCC on Linux. You can mimic this. Macs use Intel chips so you want to look at Intel syntax.

You can use this:

SELECT COUNT(*) FROM (SELECT DISTINCT column_name FROM table_name) AS temp;

This is much faster than:

COUNT(DISTINCT column_name)

System.Environment.ExitCode 

http://msdn.microsoft.com/en-us/library/system.environment.exitcode.aspx

i faced an issue something like this...

Actually, in two ways you can process find command output in copy command

1. If find command's output doesn't contain any space i.e if file name doesn't contain space in it then you can use below mentioned command:

   Syntax: find <Path> <Conditions> | xargs cp -t <copy file path>

   Example: find -mtime -1 -type f | xargs cp -t inner/

2. But most of the time our production data files might contain space in it. So most of time below mentioned command is safer:

   Syntax: find <path> <condition> -exec cp '{}' <copy path> \;

   Example find -mtime -1 -type f -exec cp '{}' inner/ \;

In the second example, last part i.e semi-colon is also considered as part of find command, that should be escaped before press the enter button. Otherwise you will get an error something like this

find: missing argument to `-exec'

In your case, copy command syntax is wrong in order to copy find file into /home/shantanu/tosend. The following command will work:

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp  {} /home/shantanu/tosend \;

In your view template, set a default value:

f.text_field :password, :value => "password"

In your Javascript (assuming jquery here):

$(document).ready(function() {
  //add a handler to remove the text
});

As for me to make the code readable in future the most useful aplyable case of enumeration is represented in next snippet:

public enum Items {
    MESSAGES, CHATS, CITY_ONLINE, FRIENDS, PROFILE, SETTINGS, PEOPLE_SEARCH, CREATE_CHAT
}

@Override
public boolean onCreateOptionsMenu(Menu menuPrm) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menuPrm);
    View itemChooserLcl;
    for (int i = 0; i < menuPrm.size(); i++) {
        MenuItem itemLcl  = menuPrm.getItem(i);
            itemChooserLcl = itemLcl.getActionView();
            if (itemChooserLcl != null) {
                 //here Im marking each View' tag by enume values:
                itemChooserLcl.setTag(Items.values()[i]);
                itemChooserLcl.setOnClickListener(drawerMenuListener);
            }
        }
    return true;
}
private View.OnClickListener drawerMenuListener=new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Items tagLcl= (Items) v.getTag();
        switch (tagLcl){
            case MESSAGES: ;
            break;
            case CHATS : ;
            break;
            case CITY_ONLINE : ;
            break;
            case FRIENDS : ;
            break;
            case  PROFILE: ;
            break;
            case  SETTINGS: ;
            break;
            case  PEOPLE_SEARCH: ;
            break;
            case  CREATE_CHAT: ;
            break;
        }
    }
};

The conflict message:

CONFLICT (delete/modify): res/layout/dialog_item.xml deleted in dialog and modified in HEAD

means that res/layout/dialog_item.xml was deleted in the 'dialog' branch you are merging, but was modified in HEAD (in the branch you are merging to).

So you have to decide whether

• remove file using "git rm res/layout/dialog_item.xml"

or

• accept version from HEAD (perhaps after editing it) with "git add res/layout/dialog_item.xml"

Then you finalize merge with "git commit".

Note that git will warn you that you are creating a merge commit, in the (rare) case where it is something you don't want. Probably remains from the days where said case was less rare.

one simple workaround is to catch the exception :

try {
        alertDialog.show()
    }
catch (WindowManager.BadTokenException e) {
        //use a log message
    }

It's not elegant but sometimes easy when you have to manage async operations and you are not sure wether activity is up or not when you want to show the dialog.

Thanks Nicholas Carey. I was going to use regex first but what you wrote changed my mind. It is so much easier to maintain this way.

//You can set these from your custom service methods
int minLen = 8;
int minDigit 2;
int minSpChar 2;

Boolean ErrorFlag = false;
//Check for password length
if (model.NewPassword.Length < minLen)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must be at least " + minLen + " characters long.");
}

//Check for Digits and Special Characters
int digitCount = 0;
int splCharCount = 0;
foreach (char c in model.NewPassword)
{
    if (char.IsDigit(c)) digitCount++;
    if (Regex.IsMatch(c.ToString(), @"[!#$%&'()*+,-.:;<=>?@[\\\]{}^_`|~]")) splCharCount++;
}

if (digitCount < minDigit)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minDigit + " digit(s).");
}
if (splCharCount < minSpChar)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minSpChar + " special character(s).");
}

if (ErrorFlag)
    return View(model);

And for my fellow Europeans, try using this:

timestamp=$(date +%d-%m-%Y_%H-%M-%S)

will give a format of the format: "15-02-2020_19-21-58"

You call the variable and get the string representation like this

$timestamp

You should have added muted attribute inside your videoElement for your code work as expected. Look bellow ..

<video id="IPcamerastream" muted="muted" autoplay src="videoplayback%20(1).mp4" width="960" height="540"></video>

Don' t forget to add a valid video link as source

This problem usually arrives when you did not have libaio.1 library installed. Install that package first and redo the mysql_install_db step.

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.

Here's the pypi https://pypi.python.org/pypi/cx_Freeze

The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html

I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.

How do I use cx_freeze?

If you use PHP5 (And you should, given that PHP4 has been deprecated), you should use PDO, since this is slowly becoming the new standard. One (very) important benefit of PDO, is that it supports bound parameters, which makes for much more secure code.

You would connect through PDO, like this:

try {
  $db = new PDO('mysql:dbname=databasename;host=127.0.0.1', 'username', 'password');
} catch (PDOException $ex) {
  echo 'Connection failed: ' . $ex->getMessage();
}

(Of course replace databasename, username and password above)

You can then query the database like this:

$result = $db->query("select * from tablename");
foreach ($result as $row) {
  echo $row['foo'] . "\n";
}

Or, if you have variables:

$stmt = $db->prepare("select * from tablename where id = :id");
$stmt->execute(array(':id' => 42));
$row = $stmt->fetch();

If you need multiple connections open at once, you can simply create multiple instances of PDO:

try {
  $db1 = new PDO('mysql:dbname=databas1;host=127.0.0.1', 'username', 'password');
  $db2 = new PDO('mysql:dbname=databas2;host=127.0.0.1', 'username', 'password');
} catch (PDOException $ex) {
  echo 'Connection failed: ' . $ex->getMessage();
}

Just start here:

https://update.angular.io

Select the version you're using and it will give you a step by step guide.

I recommend choosing 'Advanced' to see all steps. Complexity is a relative concept - and I don't know whose stupid idea this feature was, but if you select 'Basic' it won't show you all steps needed and you may miss something important that your otherwise 'Basic' application is using.

As of version 6 there is a new Angular CLI command ng update which intelligently goes through your dependencies and performs checks to make sure you're updating the right things :-)

The steps will outline how to use it :-)

The javax.naming package comprises the JNDI API. Since it's just an API, rather than an implementation, you need to tell it which implementation of JNDI to use. The implementations are typically specific to the server you're trying to talk to.

To specify an implementation, you pass in a Properties object when you construct the InitialContext. These properties specify the implementation to use, as well as the location of the server. The default InitialContext constructor is only useful when there are system properties present, but the properties are the same as if you passed them in manually.

As to which properties you need to set, that depends on your server. You need to hunt those settings down and plug them in.

I know it's an old thread, but I felt compelled to mention the translate method, which is always a good way to replace all character codes above 128 (or other if necessary).

Usage : str.translate(table[, deletechars])

>>> trans_table = ''.join( [chr(i) for i in range(128)] + [' '] * 128 )

>>> 'Résultat'.translate(trans_table)
'R sultat'
>>> '6Â 918Â 417Â 712'.translate(trans_table)
'6  918  417  712'

Starting with Python 2.6, you can also set the table to None, and use deletechars to delete the characters you don't want as in the examples shown in the standard docs at http://docs.python.org/library/stdtypes.html.

With unicode strings, the translation table is not a 256-character string but a dict with the ord() of relevant characters as keys. But anyway getting a proper ascii string from a unicode string is simple enough, using the method mentioned by truppo above, namely : unicode_string.encode("ascii", "ignore")

As a summary, if for some reason you absolutely need to get an ascii string (for instance, when you raise a standard exception with raise Exception, ascii_message ), you can use the following function:

trans_table = ''.join( [chr(i) for i in range(128)] + ['?'] * 128 )
def ascii(s):
    if isinstance(s, unicode):
        return s.encode('ascii', 'replace')
    else:
        return s.translate(trans_table)

The good thing with translate is that you can actually convert accented characters to relevant non-accented ascii characters instead of simply deleting them or replacing them by '?'. This is often useful, for instance for indexing purposes.

Check out iText; it is a pure Java PDF toolkit which has support for reading data from HTML. I used it recently in a project when I needed to pull content from our CMS and export as PDF files, and it was all rather straightforward. The support for CSS and style tags is pretty limited, but it does render tables without any problems (I never managed to set column width though).

Creating a PDF from HTML goes something like this:

Document doc = new Document(PageSize.A4);
PdfWriter.getInstance(doc, out);
doc.open();
HTMLWorker hw = new HTMLWorker(doc);
hw.parse(new StringReader(html));
doc.close();

7. Click the Download button

if you do not want to create a custom class loader. You can read the jar file stream. And transfer it to a File object. Then you can get the url of the File. Send it to the URLClassLoader, you can load the jar file as you want. sample:

InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("example"+ ".jar");
final File tempFile = File.createTempFile("temp", ".jar");
tempFile.deleteOnExit();  // you can delete the temp file or not
try (FileOutputStream out = new FileOutputStream(tempFile)) {
    IOUtils.copy(resourceAsStream, out);
}
IOUtils.closeQuietly(resourceAsStream);
URL url = tempFile.toURI().toURL();
URLClassLoader urlClassLoader = new URLClassLoader(new URL[]{url});
urlClassLoader.loadClass()
...

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

I had a similar issue, my error was:

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: java.lang.ClassNotFoundException:org.glassfish.jersey.servlet.ServletContainer from [Module "deployment.RESTful_Services_CRUD.war:main" from Service Module Loader]

I use jboss and glassfish so I changed the web.xml to the following:

<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>

Instead of:

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

Hope this work for you.

For the the accepted answer of @Joseph Silber is not working, because indexOf returns -1. This is probably because Angular adds an hashkey, which is different for my $scope.items[0] and my item. I tried to resolve this with the angular.toJson() function, but it did not work :(

Ah, I found out the reason... I use a chunk method to create two columns in my table by watching my $scope.items. Sorry!

I just spent the last 4 hours with the same issue. What I did was to simply make sure the constraints had unique names.

You can rename the constraints. I appended a number to mine so I could easily trace the number of occurrences.

Example

If a constraint in a table is named boy with a foreign key X The next constraint with the foreign key X can be called boy1

I'm sure you'd figure out better names than I did.

There are two types of site-packages directories, global and per user.

1. Global site-packages ("dist-packages") directories are listed in sys.path when you run:

   python -m site
   

   For a more concise list run getsitepackages from the site module in Python code:

   python -c 'import site; print(site.getsitepackages())'
   

   Note: With virtualenvs getsitepackages is not available, sys.path from above will list the virtualenv's site-packages directory correctly, though. In Python 3, you may use the sysconfig module instead:

   python3 -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])'
   

2. The per user site-packages directory (PEP 370) is where Python installs your local packages:

   python -m site --user-site
   

   If this points to a non-existing directory check the exit status of Python and see python -m site --help for explanations.

   Hint: Running pip list --user or pip freeze --user gives you a list of all installed per user site-packages.

Practical Tips

• <package>.__path__ lets you identify the location(s) of a specific package: (details)

  $ python -c "import setuptools as _; print(_.__path__)"
  ['/usr/lib/python2.7/dist-packages/setuptools']
  

• <module>.__file__ lets you identify the location of a specific module: (difference)

  $ python3 -c "import os as _; print(_.__file__)"
  /usr/lib/python3.6/os.py
  

• Run pip show <package> to show Debian-style package information:

  $ pip show pytest

In my code I use DATETIME DEFAULT CURRENT_TIMESTAMP as the type and constraint of the column.

In your case your table definition would be

create table notes (
  _id integer primary key autoincrement, 
  created_date date default CURRENT_DATE
)

I know your class is over, but in professional coding, let this be a lesson:

• "Deprecated" means "avoid use; it's going to be removed in the future"
• Deprecated things still work - just don't expect support or future-proofing
• If the requirement requires it, and you can't negotiate it away, just use the deprecated construct.
  
  • If you're really concerned, develop the alternative implementation on the side and keep it ready for the inevitable failure
  • Charge for the extra work now. By requesting a deprecated feature, they are asking you to double the work. You're going to see it again anyway, so might as well front-load it.
  • When the failure happens, let the interested party know that this was what you feared; that you prepared for it, but it'll take some time
  • Deploy your solution as quickly as you can (there will be bugs)
  • Gain rep for preventing excessive downtime.

Also, if your service is sending an object instead of an array add isArray:false to its declaration.

'query': {method: 'GET', isArray: false }

Alternatively to SQL, you can do this in Microsoft SQL Server Management Studio, from the table Design Panel.

First Way

Slow double-click on the column. The column name will become an editable text box.

Second Way

SqlManagement Studio>>DataBases>>tables>>specificTable>>Column Folder>>Right Click on column>>Reman

Third Way

Table>>RightClick>>Design

Yes, this form of initialization is supported by all C++ compilers. It is a part of C++ language. In fact, it is an idiom that came to C++ from C language. In C language = { 0 } is an idiomatic universal zero-initializer. This is also almost the case in C++.

Since this initalizer is universal, for bool array you don't really need a different "syntax". 0 works as an initializer for bool type as well, so

bool myBoolArray[ARRAY_SIZE] = { 0 };

is guaranteed to initialize the entire array with false. As well as

char* myPtrArray[ARRAY_SIZE] = { 0 };

in guaranteed to initialize the whole array with null-pointers of type char *.

If you believe it improves readability, you can certainly use

bool myBoolArray[ARRAY_SIZE] = { false };
char* myPtrArray[ARRAY_SIZE] = { nullptr };

but the point is that = { 0 } variant gives you exactly the same result.

However, in C++ = { 0 } might not work for all types, like enum types, for example, which cannot be initialized with integral 0. But C++ supports the shorter form

T myArray[ARRAY_SIZE] = {};

i.e. just an empty pair of {}. This will default-initialize an array of any type (assuming the elements allow default initialization), which means that for basic (scalar) types the entire array will be properly zero-initialized.

MultiProgramming - In a multiprogramming system, there are more than one programs loaded in main memory which are ready to execute. Only one program at a time is able to get the CPU for executing its instructions while all others are waiting their turn. The main idea of multiprogramming is to maximize the use of CPU time. Suppose currently running process is performing an I/O task, then OS may interrupt that process and give the control to one of the other in - main memory programs that are ready to execute (i.e. process context switching). In this way, no CPU time is wasted by system waiting for the I/O task to be completed.

MultiProcessing - Multiprocessing is the ability of an operating system to execute more than one process simultaneously on a multi processor machine. In multiprocessing system, a computer uses more than one CPU at a tme.

Multitasking - Multitasking is the ability of an operating system to execute more than one task simultaneously on single processor machine, these multiple tasks share common resources such as CPU and memory. In multitasking system, CPU switches from one task to next task so quickly that appears as all tasks are executing at the same time.

There are differences between multitasking and multiprogramming. A task in a multitasking system is not whole application program but it can refres to a "thread of execution" when one process is divided into sub-tasks. Each smaller task does not hijack the CPU until it finishes, they share a small amount of the CPU time called Quantum. Multiprogramming and multitasking operating systems are time sharing systems.

Multithreading - Multithreading is the extension of multitasking. Multithreading is the ability of an operating system to subdivide the specific operation within a single application into individual threads. Each of these threads can run in parallel. The OS divides processing time not only among different applications but also among each thread within an application.

I bumped into this problem lately with Windows 10 from another direction, and found the answer from @JonSkeet very helpful in solving my problem.

I also did som further research with a test form and found that when the the current culture was set to "no" or "nb-NO" at runtime (Thread.CurrentThread.CurrentCulture = new CultureInfo("no");), the ToString("yyyy-MM-dd HH:mm:ss") call responded differently in Windows 7 and Windows 10. It returned what I expected in Windows 7 and HH.mm.ss in Windows 10!

I think this is a bit scary! Since I believed that a culture was a culture in any Windows version at least.

Or use PyInstaller as an alternative to py2exe. Here is a good starting point. PyInstaller also lets you create executables for linux and mac...

Here is how one could fairly easily use PyInstaller to solve the issue at hand:

pyinstaller oldlogs.py

From the tool's documentation:

PyInstaller analyzes myscript.py and:

• Writes myscript.spec in the same folder as the script.
• Creates a folder build in the same folder as the script if it does not exist.
• Writes some log files and working files in the build folder.
• Creates a folder dist in the same folder as the script if it does not exist.
• Writes the myscript executable folder in the dist folder.

In the dist folder you find the bundled app you distribute to your users.

just install any package you want with -g

npm install -g express

The FileUpload.AllowMultiple property in .NET 4.5 and higher will allow you the control to select multiple files.

<asp:FileUpload ID="fileImages" AllowMultiple="true" runat="server" />

.NET 4 and below

 <asp:FileUpload ID="fileImages" Multiple="Multiple" runat="server" />

On the post-back, you can then:

 Dim flImages As HttpFileCollection = Request.Files                   
 For Each key As String In flImages.Keys
    Dim flfile As HttpPostedFile = flImages(key)
    flfile.SaveAs(yourpath & flfile.FileName)
 Next

Have you tried actually adding the Access-Control-Allow-Origin header to the response sent from your server? Like, Access-Control-Allow-Origin: *?

NSString *stringreplace=[yourString stringByReplacingOccurrencesOfString:@"search" withString:@"new_string"];

I tried the approach mentioned by Onkaar Singh,

1. Open POSTMAN
2. Click on "import" tab on the upper left side.
3. Select the Raw Text option and paste your cURL command.
4. Hit import and you will have the command in your Postman builder!

But the problem is it didn't work for the Apis which requires authorisation.

This was my curl request:

curl -v -H "Accept: application/json" -H "Content-type:
application/json" -X POST -d ' 
{"customer_id":"812122", "event":"add_to_cart", "email": "[email protected]", }' 
-u 9f4d7f5445e7: https://api.myapp.com/api/event

After importing the body got imported correctly, the headers and the Url also got imported. Only the api key 9f4d7f5445e7 which is

-u 9f4d7f5445e7: https://api.myapp.com/api/v1/event 

in the curl request did not import.

The way I solved it is, -u is basically used for Authorization. So while using it in Postman, you have to take the API key (which is 9f4d7f5445e7 in this case) and do Base64 Encode. Once encoded it will return the value OWY0ZDdmNTQ0NWU3. Then add a new header, the key name would be Authorization and key value would be Basic OWY0ZDdmNTQ0NWU3. After making that changes, the request worked for me.

There are online Base64 Encoders available, the one I used is http://www.url-encode-decode.com/base64-encode-decode/

Hope it helps!!!

Depending on your version (2012?) of SQL Server aside from the IF EXISTS you can also use MERGE like so:

ALTER PROCEDURE [dbo].[EmailsRecebidosInsert]
    ( @_DE nvarchar(50)
    , @_ASSUNTO nvarchar(50)
    , @_DATA nvarchar(30))
AS BEGIN
    MERGE [dbo].[EmailsRecebidos] [Target]
    USING (VALUES (@_DE, @_ASSUNTO, @_DATA)) [Source]([De], [Assunto], [Data])
         ON [Target].[De] = [Source].[De] AND [Target].[Assunto] = [Source].[Assunto] AND [Target].[Data] = [Source].[Data]
     WHEN NOT MATCHED THEN
        INSERT ([De], [Assunto], [Data])
        VALUES ([Source].[De], [Source].[Assunto], [Source].[Data]);
END

It seems your makefile's name is not 'Makefile' or 'makefile'. In case it is different say 'abc' try running 'make -f abc clean'

How about

SELECT user()

I use this before.MySQL, H2 is OK, I don't know others.

The issue is because you have a bean of type SuggestionService created through @Component annotation and also through the XML config . As explained by JB Nizet, this will lead to the creation of a bean with name 'suggestionService' created via @Component and another with name 'SuggestionService' created through XML .

When you refer SuggestionService by @Autowired, in your controller, Spring autowires "by type" by default and find two beans of type 'SuggestionService'

You could do the following

1. Remove @Component from your Service and depend on mapping via XML - Easiest

2. Remove SuggestionService from XML and autowire the dependencies - use util:map to inject the indexSearchers map.

3. Use @Resource instead of @Autowired to pick the bean by its name .

    @Resource(name="suggestionService")
    private SuggestionService service;
   

or

    @Resource(name="SuggestionService")
    private SuggestionService service;

both should work.The third is a dirty fix and it's best to resolve the bean conflict through other ways.

ps aux | awk '{print $4"\t"$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr

or per process

ps aux | awk '{print $4"\t"$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr |grep mysql

Go to Windows->Preferences->Validation.

There would be a list of validators with checkbox options for Manual & Build, go and individually disable the javascript validator there.

If you select the Suspend All Validators checkbox on the top it doesn't necessarily take affect.

You can use the RTrim function to trim all whitespace from the right. Use LTrim to trim all whitespace from the left. For example

UPDATE Table SET Name = RTrim(Name)

Or for both left and right trim

UPDATE Table SET Name = LTrim(RTrim(Name))

You can put in in a paragraph

<p style="text-align:center;"><a href="contact.html" class="button large hpbottom">Get Started</a></p>

To align a div in the center, you have to do 2 things: - Make the div a fixed width - Set the left and right margin properties variable

<div class="container">
 <div style="width:100px; margin:0 auto;">
     <span>a centered div</span>
  </div>
</div>

For Your JSON response you should parse that response for expected results For Instance: parsed_response = JSON.parse(response.body)

You can check other variables which is included in response like

expect(parsed_response["success"]).to eq(true)
expect(parsed_response["flashcard"]).to eq("flashcard expected value")
expect(parsed_response["lesson"]).to eq("lesson expected value")
expect(subject["status_code"]).to eq(201)

I prefer also check keys of JSON response, For Example:

expect(body_as_json.keys).to match_array(["success", "lesson","status_code", "flashcard"])

Here, We can use should matchers For expected results in Rspec

Try this:

-- http://lua-users.org/wiki/FileInputOutput

-- see if the file exists
function file_exists(file)
  local f = io.open(file, "rb")
  if f then f:close() end
  return f ~= nil
end

-- get all lines from a file, returns an empty 
-- list/table if the file does not exist
function lines_from(file)
  if not file_exists(file) then return {} end
  lines = {}
  for line in io.lines(file) do 
    lines[#lines + 1] = line
  end
  return lines
end

-- tests the functions above
local file = 'test.lua'
local lines = lines_from(file)

-- print all line numbers and their contents
for k,v in pairs(lines) do
  print('line[' .. k .. ']', v)
end

Try using this npm package. This helped me decoding the res structure from my node while using passport-azure-ad for integrating login using Microsoft account

https://www.npmjs.com/package/circular-json

You can stringify your circular structure by doing:

const str = CircularJSON.stringify(obj);

then you can convert it onto JSON using JSON parser

JSON.parse(str)

if( strtotime($database_date) > strtotime('now') ) {
...

Although <input> ignores the rows attribute, you can take advantage of the fact that <textarea> doesn't have to be inside <form> tags, but can still be a part of a form by referencing the form's id:

<form method="get" id="testformid">
    <input type="submit" />
</form> 
<textarea form ="testformid" name="taname" id="taid" cols="35" wrap="soft"></textarea>

Of course, <textarea> now appears below "submit" button, but maybe you'll find a way to reposition it.

We could also specify the files, to include just the files with relative changes, particularly when they span multiple directories e.x.

git diff ~/path1/file1.ext ~/path2/file2.ext...fileN.ext > ~/whatever_path/whatever_name.patch

I found this to be not specified in the answers or comments, which are all relevant and correct, so chose to add it. Explicit is better than implicit!

If you have array like:

$runners = ["1","2","3","4"];

And if you want to covert them into integers and keep within array, following should do the job:

$newArray = array_map( create_function('$value', 'return (int)$value;'),
            $runners);

To make a vertical line, just use a rectangle with width of 1dp:

<shape>
    <size
        android:width="1dp"
        android:height="16dp" />
    <solid
        android:color="#c8cdd2" />
</shape>

Don't use stroke, use solid (which is the "fill" color) to specify the color of the line.

With Intellij Toggle Skip Test Mode can be used from Maven Projects tab:

final keyword in the method input parameter is not needed. Java creates a copy of the reference to the object, so putting final on it doesn't make the object final but just the reference, which doesn't make sense

For me, the server was expect HTTPS requests, but I didn't specify that in the URL. The hook would reach the server, but the body would be empty.

I use a variation of the Singleton design pattern to help me with this.

import android.app.Activity;
import android.content.Context;

public class ApplicationContextSingleton {
    private static Activity gContext;

    public static void setContext( Activity activity) {
        gContext = activity;
    }

    public static Activity getActivity() {
        return gContext;
    }

    public static Context getContext() {
        return gContext;
    }
}

I then call ApplicationContextSingleton.setContext( this ); in my activity.onCreate() and ApplicationContextSingleton.setContext( null ); in onDestroy();

easiest way:

Dim newBook As Workbook  
Set newBook = Workbooks.Add

Sheets("Sheet1").Copy Before:=newBook.Sheets(1)

You don't need the inheritance. You can do:

(Foo)1 

it will work ;)

following @tony's approach, changed the getTableHeight() function to

<div id="grid1" ui-grid="$ctrl.gridOptions" class="grid" ui-grid-auto-resize style="{{$ctrl.getTableHeight()}}"></div>

getTableHeight() {
    var offsetValue = 365;
    return "height: " + parseInt(window.innerHeight - offsetValue ) + "px!important";
}

the grid would have a dynamic height with regards to window height as well.

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

Since nowadays, computers support widely any length as file type, the choice is now only personal. Back in the early days of Windows where only 3 letters where supported, you had to use .htm, but not anymore.

This fixed the problem by having it as the first two lines of the script:

!pip install opencv-python
!apt update && apt install -y libsm6 libxext6
!apt-get install -y libxrender-dev

Edited to reflect update to question

$(document).ready(function() {
    $(".res a").click(function() {
        alert($(this).attr("href"));
    });
});

Inspired by Solomon's answer, but to stick with the question, which is related to histogram, a clean solution is:

sns.distplot(bar)
sns.distplot(foo)
plt.show()

Make sure to plot the taller one first, otherwise you would need to set plt.ylim(0,0.45) so that the taller histogram is not chopped off.

1) use for tommorow's date startDate: '+1d'

2) use for yesterday's date startDate: '-1d'

3) use for today's date startDate: new Date()

Just try this in razor

@{
    var selectList = new SelectList(
        new List<SelectListItem>
        {
            new SelectListItem {Text = "Google", Value = "Google"},
            new SelectListItem {Text = "Other", Value = "Other"},
        }, "Value", "Text");
}

and then

@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })

or

@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })

Posting new answer since Angular behavior has changed. Checking equality with undefined now works in angular expressions, at least as of 1.5, as the following code works:

ng-if="foo !== undefined"

When this ng-if evaluates to true, deleting the percentages property off the appropriate scope and calling $digest removes the element from the document, as you would expect.

Here is how you can check if the token exists:

if (jobject["Result"].SelectToken("Items") != null) { ... }

It checks if "Items" exists in "Result".

This is a NOT working example that causes exception:

if (jobject["Result"]["Items"] != null) { ... }

To be able to build with C# 6 syntax use this in path:

C:\Program Files (x86)\MSBuild\14.0\Bin

pid_t child_pid, wpid;
int status = 0;

//Father code (before child processes start)

for (int id=0; id<n; id++) {
    if ((child_pid = fork()) == 0) {
        //child code
        exit(0);
    }
}

while ((wpid = wait(&status)) > 0); // this way, the father waits for all the child processes 

//Father code (After all child processes end)

wait waits for a child process to terminate, and returns that child process's pid. On error (eg when there are no child processes), -1 is returned. So, basically, the code keeps waiting for child processes to finish, until the waiting errors out, and then you know they are all finished.

use

<div class="btn-group btn-group-justified">
  ...
</div>

but it only works for <a> elements and not <button> elements.

see: http://getbootstrap.com/components/#btn-groups-justified

Try this:

Function UserNameWindows() As String
     UserName = Environ("USERNAME")
End Function

Not currently, currently the only languages available to access the iPhone SDK are C/C++, Objective C and Swift.

There is no technical reason why this could not change in the future but I wouldn't hold your breath for this happening in the short term.

That said, Objective-C and Swift really are not too scary...

2016 edit

Javascript with NativeScript framework is available to use now.

Applies to Bootstrap 3 only.

Ignoring the letters (xs, sm, md, lg) for now, I'll start with just the numbers...

• the numbers (1-12) represent a portion of the total width of any div
• all divs are divided into 12 columns
• so, col-*-6 spans 6 of 12 columns (half the width), col-*-12 spans 12 of 12 columns (the entire width), etc

So, if you want two equal columns to span a div, write

<div class="col-xs-6">Column 1</div>
<div class="col-xs-6">Column 2</div>

Or, if you want three unequal columns to span that same width, you could write:

<div class="col-xs-2">Column 1</div>
<div class="col-xs-6">Column 2</div>
<div class="col-xs-4">Column 3</div>

You'll notice the # of columns always add up to 12. It can be less than twelve, but beware if more than 12, as your offending divs will bump down to the next row (not .row, which is another story altogether).

You can also nest columns within columns, (best with a .row wrapper around them) such as:

<div class="col-xs-6">
  <div class="row">
    <div class="col-xs-4">Column 1-a</div>
    <div class="col-xs-8">Column 1-b</div>
  </div>
</div>
<div class="col-xs-6">
  <div class="row">
    <div class="col-xs-2">Column 2-a</div>
    <div class="col-xs-10">Column 2-b</div>
  </div>
</div>

Each set of nested divs also span up to 12 columns of their parent div. NOTE: Since each .col class has 15px padding on either side, you should usually wrap nested columns in a .row, which has -15px margins. This avoids duplicating the padding and keeps the content lined up between nested and non-nested col classes.

-- You didn't specifically ask about the xs, sm, md, lg usage, but they go hand-in-hand so I can't help but touch on it...

In short, they are used to define at which screen size that class should apply:

• xs = extra small screens (mobile phones)
• sm = small screens (tablets)
• md = medium screens (some desktops)
• lg = large screens (remaining desktops)

Read the "Grid Options" chapter from the official Bootstrap documentation for more details.

You should usually classify a div using multiple column classes so it behaves differently depending on the screen size (this is the heart of what makes bootstrap responsive). eg: a div with classes col-xs-6 and col-sm-4 will span half the screen on the mobile phone (xs) and 1/3 of the screen on tablets(sm).

<div class="col-xs-6 col-sm-4">Column 1</div> <!-- 1/2 width on mobile, 1/3 screen on tablet) -->
<div class="col-xs-6 col-sm-8">Column 2</div> <!-- 1/2 width on mobile, 2/3 width on tablet -->

NOTE: as per comment below, grid classes for a given screen size apply to that screen size and larger unless another declaration overrides it (i.e. col-xs-6 col-md-4 spans 6 columns on xs and sm, and 4 columns on md and lg, even though sm and lg were never explicitly declared)

NOTE: if you don't define xs, it will default to col-xs-12 (i.e. col-sm-6 is half the width on sm, md and lg screens, but full-width on xs screens).

NOTE: it's actually totally fine if your .row includes more than 12 cols, as long as you are aware of how they will react. --This is a contentious issue, and not everyone agrees.

Prim's is better for more dense graphs, and in this we also do not have to pay much attention to cycles by adding an edge, as we are primarily dealing with nodes. Prim's is faster than Kruskal's in the case of complex graphs.

Responding to your question about List<T>:

List<T> is a class; specifying an interface allows more flexibility of implementation. A better question is "why not IList<T>?"

To answer that question, consider what IList<T> adds to ICollection<T>: integer indexing, which means the items have some arbitrary order, and can be retrieved by reference to that order. This is probably not meaningful in most cases, since items probably need to be ordered differently in different contexts.

date +%s

This works fine for me on OS X Lion.

For newer version of python:

exec(open(filename).read())

More based on the feeling, but this is the error you would get if you missed to declare a bean in the context configuration, so try adding

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10000000"/>
</bean>

The Bourne shell and C shell don't have arrays, IIRC.

In addition to what others have said, in Bash you can get the number of elements in an array as follows:

elements=${#arrayname[@]}

and do slice-style operations:

arrayname=(apple banana cherry)
echo ${arrayname[@]:1}                   # yields "banana cherry"
echo ${arrayname[@]: -1}                 # yields "cherry"
echo ${arrayname[${#arrayname[@]}-1]}    # yields "cherry"
echo ${arrayname[@]:0:2}                 # yields "apple banana"
echo ${arrayname[@]:1:1}                 # yields "banana"

I had the same problem. Restart my android phone device worked for me.

By default, Button in android provides all caps keyword. If you want button text to be in lower case or mixed case you can disable textAllCaps flag using android:textAllCaps="false"

Almost 99% of the time there is no need for an Android application to take over its own life cycle. Most of the time it comes down to better planning or smarter design of the application. For example, rather build an internal service (not exported) to handle downloads, etc., or design actions and tasks around user workflow.

But that being said, where there is a will there is a way. Android provides - through the android.os.Process class, a much better API than Java to control the underlying process. And unlike Java it does not treat the developer like a moron by hiding it all behind a simple java.lang.System.exit() call.

So how do you ask your application to commit suicide in Android? Well, the trick is simple:

Create your own Android application class by inheriting from the standard android.app.Application class (remember to declare it in the AndroidManifest.xml file).

Override the onCreate() method, and store the process ID which started your application:

this.pid = android.os.Process.myPid(); // Save for later use.

Now to kill your application, provide a kill() method:

android.os.Process.sendSignal(pid, android.os.Process.SIGNAL_KILL);

Now whenever you need your app to commit suicide just type cast the application context, and call your kill method!

((MySuicidalApp) context.getApplicationContext()).kill()

Just remember that due to the process management policies in Android, specifically related to services, Android may just opt to restart your service (see You should not use task killers on Android).

I had this problem in one legacy application that create prepared statement dynamically.

String firstName;
StringBuilder query =new StringBuilder("select id, name from employee where country_Code=1");
query.append("and  name like '");
query.append(firstName + "' ");
query.append("and ssn=?");
PreparedStatement preparedStatement =new prepareStatement(query.toString());

when it try to set value for ssn, it was giving invalid column index error, and finally found out that it is caused by firstName having ' within; that disturb the syntax.

Static method is inherited in subclass but it is not polymorphism. When you writing the implementation of static method, the parent's class method is over hidden, not overridden. Think, if it is not inherited then how you can be able to access without classname.staticMethodname();?

I agree with Reto and fiXedd. Objectively speaking it doesn't make a lot of sense investing significant time and effort into encrypting passwords in SharedPreferences since any attacker that has access to your preferences file is fairly likely to also have access to your application's binary, and therefore the keys to unencrypt the password.

However, that being said, there does seem to be a publicity initiative going on identifying mobile applications that store their passwords in cleartext in SharedPreferences and shining unfavorable light on those applications. See http://blogs.wsj.com/digits/2011/06/08/some-top-apps-put-data-at-risk/ and http://viaforensics.com/appwatchdog for some examples.

While we need more attention paid to security in general, I would argue that this sort of attention on this one particular issue doesn't actually significantly increase our overall security. However, perceptions being as they are, here's a solution to encrypt the data you place in SharedPreferences.

Simply wrap your own SharedPreferences object in this one, and any data you read/write will be automatically encrypted and decrypted. eg.

final SharedPreferences prefs = new ObscuredSharedPreferences( 
    this, this.getSharedPreferences(MY_PREFS_FILE_NAME, Context.MODE_PRIVATE) );

// eg.    
prefs.edit().putString("foo","bar").commit();
prefs.getString("foo", null);

Here's the code for the class:

/**
 * Warning, this gives a false sense of security.  If an attacker has enough access to
 * acquire your password store, then he almost certainly has enough access to acquire your
 * source binary and figure out your encryption key.  However, it will prevent casual
 * investigators from acquiring passwords, and thereby may prevent undesired negative
 * publicity.

When i Tried your Code i got en Error when i wanted to fill the Array.

you can try to fill the Array like This.

Sub Testing_Data()
Dim k As Long, S2 As Worksheet, VArray

Application.ScreenUpdating = False
Set S2 = ThisWorkbook.Sheets("Sheet1")
With S2
    VArray = .Range("A1:A" & .Cells(Rows.Count, "A").End(xlUp).Row)
End With
For k = 2 To UBound(VArray, 1)
    S2.Cells(k, "B") = VArray(k, 1) / 100
    S2.Cells(k, "C") = VArray(k, 1) * S2.Cells(k, "B")
Next

End Sub

ClassLoader.getResourceAsStream().

As stated in the comment below, if you are in a multi-ClassLoader environment (such as unit testing, webapps, etc.) you may need to use Thread.currentThread().getContextClassLoader(). See http://stackoverflow.com/questions/2308188/getresourceasstream-vs-fileinputstream/2308388#comment21307593_2308388.

Try this:

counter=0
while true; do
  if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
       echo "Files Present" | mailx -s "File Present"  -r [email protected] [email protected]
       break
  elif [[ "$counter" -gt 20 ]]; then
       echo "Counter limit reached, exit script."
       exit 1
  else
       let counter++
       echo "Sleeping for another half an hour" | mailx -s "Time to Sleep Now"  -r [email protected] [email protected]
       sleep 1800
  fi
done

Explanation

• break - if files are present, it will break and allow the script to process the files.
• [[ "$counter" -gt 20 ]] - if the counter variable is greater than 20, the script will exit.
• let counter++ - increments the counter by 1 at each pass.

It works like this. View.OnClickListenere is defined -

public interface OnClickListener {
    void onClick(View v);
}

As far as we know you cannot instantiate an object OnClickListener, as it doesn't have a method implemented. So there are two ways you can go by - you can implement this interface which will override onClick method like this:

public class MyListener implements View.OnClickListener {
    @Override
    public void onClick (View v) {
         // your code here;
    }
}

But it's tedious to do it each time as you want to set a click listener. So in order to avoid this you can provide the implementation for the method on spot, just like in an example you gave.

setOnClickListener takes View.OnClickListener as its parameter.

Since MongoDB version 3.2 you can use updateMany():

> db.yourCollection.updateMany({}, {$set:{"someField": "someValue"}})

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.

Taking help from above answer link mentioned in the above answer sets the max value with option

yAxis: { max: 100 },

On similar line min value can be set.So if you want to set min-max value then

yAxis: {
   min: 0,     
   max: 100
},

If you are using HighRoller php library for integration if Highchart graphs then you just need to set the option

$series->yAxis->min=0;
$series->yAxis->max=100;

string MyConString = "Data Source='mysql7.000webhost.com';" +
"Port=3306;" +
"Database='a455555_test';" +
"UID='a455555_me';" +
"PWD='something';";

Since I've been looking for this forever, and I found a solution a while ago which is missing here, I'm gonna write it here, for future reference also.

Note: this code was taken directly from Google Android Lollipop dialer a while back, I don't remember If changes were made at the time. Also, I don't know which license is this under, but I have reason to think it is Apache 2.0.

Class ResizeTextView, the actual View

public class ResizeTextView extends TextView {

private final int mOriginalTextSize;
private final int mMinTextSize;
private final static int sMinSize = 20;
public ResizeTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    mOriginalTextSize = (int) getTextSize();
    mMinTextSize = (int) sMinSize;
}
@Override
protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) {
    super.onTextChanged(text, start, lengthBefore, lengthAfter);
    ViewUtil.resizeText(this, mOriginalTextSize, mMinTextSize);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(w, h, oldw, oldh);
    ViewUtil.resizeText(this, mOriginalTextSize, mMinTextSize);
}

This ResizeTextView class could extend TextView and all its children as I undestand, so EditText as well.

public class ViewUtil {

    private ViewUtil() {}

    public static void resizeText(TextView textView, int originalTextSize, int minTextSize) {
        final Paint paint = textView.getPaint();
        final int width = textView.getWidth();

You should set your view as

            android:gravity="center"

Hope it helps!

There is an hard limit on how much data can be stored in a single row of a mysql table, regardless of the number of columns or the individual column length.

As stated in the OFFICIAL DOCUMENTATION

The maximum row size constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size. For example, utf8 characters require up to three bytes per character, so for a CHAR(255) CHARACTER SET utf8 column, the server must allocate 255 × 3 = 765 bytes per value. Consequently, a table cannot contain more than 65,535 / 765 = 85 such columns.

Storage for variable-length columns includes length bytes, which are assessed against the row size. For example, a VARCHAR(255) CHARACTER SET utf8 column takes two bytes to store the length of the value, so each value can take up to 767 bytes.

Here you can find INNODB TABLES LIMITATIONS

If your existing code is already relying on from datetime import datetime, you can also simply also import date

from datetime import datetime, timedelta, date
print isinstance(datetime.today().date(), date)

Have a look at the start up scripts a Java heap size is set there, it looks like you're not setting this before running Spark worker.

# Set SPARK_MEM if it isn't already set since we also use it for this process
SPARK_MEM=${SPARK_MEM:-512m}
export SPARK_MEM

# Set JAVA_OPTS to be able to load native libraries and to set heap size
JAVA_OPTS="$OUR_JAVA_OPTS"
JAVA_OPTS="$JAVA_OPTS -Djava.library.path=$SPARK_LIBRARY_PATH"
JAVA_OPTS="$JAVA_OPTS -Xms$SPARK_MEM -Xmx$SPARK_MEM"

You can find the documentation to deploy scripts here.

just to update this, bootstrap v2 no longer conflicts with jquery ui

https://github.com/twbs/bootstrap/issues/171

Edit: as @Freshblood there are a few things that still conflict. However, as originally posted Twitter suggests that they are working on this and it largely works, specially compared to v1.

Here's a good drop-in solution for perfectly centered circular X icon buttons

• Using only CSS
• Not relying on a font
• The thickness and length of the tines of the X can be configured without affecting centering, using width and height in the pseudo element rule .close::before, .close::after
• Screen reader support using aria-label
• Works on a light or dark background by using transparent grays and currentColor to adapt to the current text color specified on the button or an ancestor.

.close {
    vertical-align: middle;
    border: none;
    color: inherit;
    border-radius: 50%;
    background: transparent;
    position: relative;
    width: 32px;
    height: 32px;
    opacity: 0.6;
}
.close:focus,
.close:hover {
    opacity: 1;
    background: rgba(128, 128, 128, 0.5);
}
.close:active {
    background: rgba(128, 128, 128, 0.9);
}
/* tines of the X */
.close::before,
.close::after {
    content: " ";
    position: absolute;
    top: 50%;
    left: 50%;
    height: 20px;
    width: 4px;
    background-color: currentColor;
}
.close::before {
    transform: translate(-50%, -50%) rotate(45deg);
}
.close::after {
    transform: translate(-50%, -50%) rotate(-45deg);
}

<div style="padding: 15px">
    <button class="close" aria-label="Close"></button>
</div>
<div style="background: black; color: white; padding: 15px">
    <button class="close" aria-label="Close"></button>
</div>
<div style="background: orange; color: yellow; padding: 15px">
    <button class="close" aria-label="Close"></button>
</div>

An alternative for multiline texts or links, you can wrap your texts in a span inside a block element.

<a href="#">
    <span>insert multiline texts here</span>
</a> 

then you can just add border-bottom and padding on the <span>.

a {
  width: 300px;
  display: block;
}

span {
  padding-bottom: 10px;
  border-bottom: 1px solid #0099d3;
  line-height: 48px;
}

You may refer to this fiddle. https://jsfiddle.net/Aishaterr/vrpb2ey7/2/

You'll get converting errors with:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

Use instead:

string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
    found = true; 
} else {
    found = false; 
}

You're not actually going out after the values. You would need to gather them like this:

var title   = document.getElementById("title").value;
var name    = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;

You could put all of these in one array:

var myArray = [ title, name, tickets ];

Or many arrays:

var titleArr   = [ title ];
var nameArr    = [ name ];
var ticketsArr = [ tickets ];

Or, if the arrays already exist, you can use their .push() method to push new values onto it:

var titleArr = [];

function addTitle ( title ) {
  titleArr.push( title );
  console.log( "Titles: " + titleArr.join(", ") );
}

Your save button doesn't work because you refer to this.form, however you don't have a form on the page. In order for this to work you would need to have <form> tags wrapping your fields:

I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit

The new form follows:

<form>
  <h1>Please enter data</h1>
  <input id="title" type="text" />
  <input id="name" type="text" />
  <input id="tickets" type="text" />
  <input type="button" value="Save" onclick="insert()" />
  <input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>

There is still some room for improvement, such as removing the onclick attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).

I've also made some changes to your JavaScript. I start by creating three empty arrays:

var titles  = [];
var names   = [];
var tickets = [];

Now that we have these, we'll need references to our input fields.

var titleInput  = document.getElementById("title");
var nameInput   = document.getElementById("name");
var ticketInput = document.getElementById("tickets");

I'm also getting a reference to our message display box.

var messageBox  = document.getElementById("display");

The insert() function uses the references to each input field to get their value. It then uses the push() method on the respective arrays to put the current value into the array.

Once it's done, it cals the clearAndShow() function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.

function insert ( ) {
 titles.push( titleInput.value );
 names.push( nameInput.value );
 tickets.push( ticketInput.value );

 clearAndShow();
}

This function, as previously stated, starts by setting the .value property of each input to an empty string. It then clears out the .innerHTML of our message box. Lastly, it calls the join() method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.

function clearAndShow () {
  titleInput.value = "";
  nameInput.value = "";
  ticketInput.value = "";

  messageBox.innerHTML = "";

  messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
  messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
  messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

The final result can be used online at http://jsbin.com/ufanep/2/edit

In 12c you can make use of the fact that columns which are set from invisible to visible are displayed as the last column of the table: Tips and Tricks: Invisible Columns in Oracle Database 12c

Maybe that is the 'trick' @jeffrey-kemp was talking about in his comment, but the link there does not work anymore.

Example:

ALTER TABLE my_tab ADD (col_3 NUMBER(10));
ALTER TABLE my_tab MODIFY (
  col_1 invisible,
  col_2 invisible
);
ALTER TABLE my_tab MODIFY (
  col_1 visible,
  col_2 visible
);

Now col_3 would be displayed first in a SELECT * FROM my_tab statement.

Note: This does not change the physical order of the columns on disk, but in most cases that is not what you want to do anyway. If you really want to change the physical order, you can use the DBMS_REDEFINITION package.

Here's a nice fun LINQ example.

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

Properties are used to encapsulate some data. You could use a plain field:

public string MyField

But this field can be accessed by all outside users of your class. People can insert illegal values or change the value in ways you didn't expect.

By using a property, you can encapsulate the way your data is accessed. C# has a nice syntax for turning a field into a property:

string MyProperty { get; set; }

This is called an auto-implemented property. When the need arises you can expand your property to:

string _myProperty;

public string MyProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

Now you can add code that validates the value in your setter:

set
{
    if (string.IsNullOrWhiteSpace(value))
        throw new ArgumentNullException();

    _myProperty = value;
}

Properties can also have different accessors for the getter and the setter:

public string MyProperty { get; private set; }

This way you create a property that can be read by everyone but can only be modified by the class itself.

You can also add a completely custom implementation for your getter:

public string MyProperty
{
    get
    {
        return DateTime.Now.Second.ToString();
    }
}

When C# compiles your auto-implemented property, it generates Intermediate Language (IL). In your IL you will see a get_MyProperty and set_MyProperty method. It also creates a backing field called <MyProperty>k_BackingField (normally this would be an illegal name in C# but in IL it's valid. This way you won't get any conflicts between generated types and your own code). However, you should use the official property syntax in C#. This creates a nicer experience in C# (for example with IntelliSense).

By convention, you shouldn't use properties for operations that take a long time.

If you have https server, change your url to use https:// protocol.

I got into similar issue with this one. My url has http:// protocol and I want to make a POST request, but the server wants to redirect it to https. What happen is that, turns out to be node http behavior sends the redirect request (next) in GET method which is not the case.

What I did is to change my url to https:// protocol and it works.

is.nan.data.frame <- function(x)
do.call(cbind, lapply(x, is.nan))

data123[is.nan(data123)] <- 0

It generally it helps to avoid SQL injection, for example consider the following code:

<?php
// Query database to check if there are any matching users
$query = "SELECT * FROM users WHERE user='{$_POST['username']}' AND password='{$_POST['password']}'";
mysql_query($query);

// We didn't check $_POST['password'], it could be anything the user wanted! For example:
$_POST['username'] = 'aidan';
$_POST['password'] = "' OR ''='";

// This means the query sent to MySQL would be:
echo $query;
?>

and a hacker can send a query like:

SELECT * FROM users WHERE user='aidan' AND password='' OR ''=''

This would allow anyone to log in without a valid password.

Seems like it is impossible to link icu4c using brew after latest OS X update. Which makes things more interesting. The only solution I found working for me:

1. Download and compile icu4c 62.1 to /usr/local/icu4c/62.1

mkdir ~/sources
cd ~/sources
wget http://download.icu-project.org/files/icu4c/62.1/icu4c-62_1-src.tgz
tar xvzf icu4c-62_1-src.tgz
cd icu/source/

sudo mkdir /usr/local/icu4c/62.1
./configure --prefix=/usr/local/icu4c/62.1
make
sudo make install

2. Link libs:

ln -s /usr/local/icu4c/62.1/lib/*.dylib /usr/local/include/

3. Set DYLD_LIBRARY_PATH in ~/.bash_profile:

export DYLD_LIBRARY_PATH=/usr/local/include

Yes, you can use a while True: loop that never breaks to run Python code continually.

However, you will need to put the code you want to run continually inside the loop:

#!/usr/bin/python

while True:
    # some python code that I want 
    # to keep on running

Also, time.sleep is used to suspend the operation of a script for a period of time. So, since you want yours to run continually, I don't see why you would use it.

I know this is an older post but I updated the code found in the link (which is dead as of 2013-12-03) mentioned in the answer posted by Matt Rogish:

DECLARE @ver nvarchar(128)
SET @ver = CAST(serverproperty('ProductVersion') AS nvarchar)
SET @ver = SUBSTRING(@ver, 1, CHARINDEX('.', @ver) - 1)

IF ( @ver = '7' )
   SELECT 'SQL Server 7'
ELSE IF ( @ver = '8' )
   SELECT 'SQL Server 2000'
ELSE IF ( @ver = '9' )
   SELECT 'SQL Server 2005'
ELSE IF ( @ver = '10' )
   SELECT 'SQL Server 2008/2008 R2'
ELSE IF ( @ver = '11' )
   SELECT 'SQL Server 2012'
ELSE IF ( @ver = '12' )
   SELECT 'SQL Server 2014'
ELSE IF ( @ver = '13' )
   SELECT 'SQL Server 2016'
ELSE IF ( @ver = '14' )
   SELECT 'SQL Server 2017'
ELSE
   SELECT 'Unsupported SQL Server Version'
