In your Controller

public function updtitle() 
{   
    $data = array(
        'table_name' => 'your_table_name_to_update', // pass the real table name
        'id' => $this->input->post('id'),
        'title' => $this->input->post('title')
    );

    $this->load->model('Updmodel'); // load the model first
    if($this->Updmodel->upddata($data)) // call the method from the model
    {
        // update successful
    }
    else
    {
        // update not successful
    }

}

In Your Model

public function upddata($data) {
    extract($data);
    $this->db->where('emp_no', $id);
    $this->db->update($table_name, array('title' => $title));
    return true;
}

The active record query is similar to

"update $table_name set title='$title' where emp_no=$id"

This solution depends on Bootstrap 3, as pointed out by @günther-jena

Try <a class="btn text-right">Call to Action</a>. This way you don't need extra markup or rules to clear out floated elements.

To access any element of a list in a YAML file like this:

global:
  registry:
    url: dtr-:5000/
    repoPath:
  dbConnectionString: jdbc:oracle:thin:@x.x.x.x:1521:abcd

You can use following python script:

import yaml

with open("/some/path/to/yaml.file", 'r') as f:
    valuesYaml = yaml.load(f, Loader=yaml.FullLoader)

print(valuesYaml['global']['dbConnectionString'])

I'm using the code below. working

@Query(value = "select * from user usr" +
  "left join apl apl on usr.user_id = apl.id" +
  "left join lang on lang.role_id = usr.role_id" +
  "where apl.scr_name like %:scrname% and apl.uname like %:uname and usr.role_id in :roleIds ORDER BY ?#{#pageable}",
  countQuery = "select count(*) from user usr" +
      "left join apl apl on usr.user_id = apl.id" +
      "left join lang on lang.role_id = usr.role_id" +
      "where apl.scr_name like %:scrname% and apl.uname like %:uname and usr.role_id in :roleIds",
  nativeQuery = true)
Page<AplUserEntity> searchUser(@Param("scrname") String scrname,@Param("uname") String  uname,@Param("roleIds") List<Long> roleIds,Pageable pageable);

The @supports rule (92% browser support July 2017) rule can be used for conditional logic on css properties:

@supports (display: -webkit-box) {
    .for_older_webkit_browser { display: -webkit-box }
}

@supports not (display: -webkit-box) {
    .newer_browsers { display: flex } 
}

You can use below method :

Route::getCurrentRoute()->getPath();

In Laravel version > 6.0, You can use below methods:

$route = Route::current();

$name = Route::currentRouteName();

$action = Route::currentRouteAction();

If you're targeting HTML5 only you can use:

<input type="text" id="firstname" placeholder="First Name:" />

For non HTML5 browsers, I would build upon Floern's answer by using jQuery and make the javascript non-obtrusive. I would also use a class to define the blurred properties.

$(document).ready(function () {

    //Set the initial blur (unless its highlighted by default)
    inputBlur($('#Comments'));

    $('#Comments').blur(function () {
        inputBlur(this);
    });
    $('#Comments').focus(function () {
        inputFocus(this);
    });

})

Functions:

function inputFocus(i) {
    if (i.value == i.defaultValue) {
        i.value = "";
        $(i).removeClass("blurredDefaultText");
    }
}
function inputBlur(i) {
    if (i.value == "" || i.value == i.defaultValue) {
        i.value = i.defaultValue;
        $(i).addClass("blurredDefaultText");
    }
}

CSS:

.blurredDefaultText {
    color:#888 !important;
}

Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).

Anyways, if you're already planning on using MSYS2, there's no need for that installer.

1. Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).

2. After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).

3. Install a toolchain

   a) for 32-bit:

   pacman -S mingw-w64-i686-gcc
   

   b) for 64-bit:

   pacman -S mingw-w64-x86_64-gcc
   

4. install any libraries/tools you may need. You can search the repositories by doing

   pacman -Ss name_of_something_i_want_to_install
   

   e.g.

   pacman -Ss gsl
   

   and install using

   pacman -S package_name_of_something_i_want_to_install
   

   e.g.

   pacman -S mingw-w64-x86_64-gsl
   

   and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!

5. Open a MinGW-w64 shell:

   a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"

   b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"

6. Verify that the compiler is working by doing

   gcc -v
   

If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin or <MSYS2 root>/mingw64/bin to your PATH.

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

Swift 4 provides merging(_:uniquingKeysWith:), so for your case:

let combinedDict = dict1.merging(dict2) { $1 }

The shorthand closure returns $1, therefore dict2's value will be used when there is a conflict with the keys.

To calculate the distance you need signal strength and frequency of the signal. Here is the java code:

public double calculateDistance(double signalLevelInDb, double freqInMHz) {
    double exp = (27.55 - (20 * Math.log10(freqInMHz)) + Math.abs(signalLevelInDb)) / 20.0;
    return Math.pow(10.0, exp);
}

The formula used is:

distance = 10 ^ ((27.55 - (20 * log10(frequency)) + signalLevel)/20)

Example: frequency = 2412MHz, signalLevel = -57dbm, result = 7.000397427391188m

This formula is transformed form of Free Space Path Loss(FSPL) formula. Here the distance is measured in meters and the frequency - in megahertz. For other measures you have to use different constant (27.55). Read for the constants here.

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Expanding on the two previous answers, if you just want Objective-C but not any of the Cocoa frameworks, then gcc will work on any platform. You can use it through Cygwin or get MinGW. However, if you want the Cocoa frameworks, or at least a reasonable subset of them, then GNUStep and Cocotron are your best bets.

Cocotron implements a lot of stuff that GNUStep does not, such as CoreGraphics and CoreData, though I can't vouch for how complete their implementation is on a specific framework. Their aim is to keep Cocotron up to date with the latest version of OS X so that any viable OS X program can run on Windows. Because GNUStep typically uses the latest version of gcc, they also add in support for Objective-C++ and a lot of the Objective-C 2.0 features.

I haven't tested those features with GNUStep, but if you use a sufficiently new version of gcc, you might be able to use them. I was not able to use Objective-C++ with GNUStep a few years ago. However, GNUStep does compile from just about any platform. Cocotron is a very mac-centric project. Although it is probably possible to compile it on other platforms, it comes XCode project files, not makefiles, so you can only compile its frameworks out of the box on OS X. It also comes with instructions on compiling Windows apps on XCode, but not any other platform. Basically, it's probably possible to set up a Windows development environment for Cocotron, but it's not as easy as setting one up for GNUStep, and you'll be on your own, so GNUStep is definitely the way to go if you're developing on Windows as opposed to just for Windows.

For what it's worth, Cocotron is licensed under the MIT license, and GNUStep is licensed under the LGPL.

This works successfully.

1. an API(Application Programming Interface) is a set of defined functions and methods for interfacing with the underlying operating system or another program or service running on the computer.

2. It is usually used by establishing a reference to a library in your software or importing a function from a dll.

3. It is used in one form or another in almost all software, being explicitly called in your program or implicitly called by the compiler.

$sort = array();
$array_lowercase = array_map('strtolower', $array_to_be_sorted);
array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $alphabetically_ordered_array);

This takes care of both upper and lower case alphabets.

You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:

Sub test()
Dim wb As Excel.Workbook
Set wb = Workbooks.Add
With wb.Sheets(1)
    .Range("A1") = "Acctdate"
    .Range("B1") = "Ledger"
    .Range("C1") = "CY"
    .Range("D1") = "BusinessUnit"
    .Range("E1") = "OperatingUnit"
    .Range("F1") = "LOB"
    .Range("G1") = "Account"
    .Range("H1") = "TreatyCode"
    .Range("I1") = "Amount"
    .Range("J1") = "TransactionCurrency"
    .Range("K1") = "USDEquivalentAmount"
    .Range("L1") = "KeyCol"
    .Range("A2", "A50000").Value = Me.TextBox3.Value
    .Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
End With
End Sub

To fix this error on Centos 7:

1. Install PHP extension:

   sudo yum install php-xml

2. Restart your web server. In my case it's php-fpm:

   services php-fpm restart

I am trying to parse that weird windows apostraphe and after trying several things here is the code snippet that works.

def convert_freaking_apostrophe(self,string):

   try:
      issuer_rename = string.decode('windows-1252')
   except:
      issuer_rename = string.decode('latin-1')
   issuer_rename = issuer_rename.replace(u'’', u"'")
   issuer_rename = issuer_rename.encode('ascii','ignore')
   try:
      os.rename(directory+"/"+issuer,directory+"/"+issuer_rename)
      print "Successfully renamed "+issuer+" to "+issuer_rename
      return issuer_rename
   except:
      pass

#HANDLING FOR FUNKY APOSTRAPHE
if re.search(r"([\x90-\xff])", issuer):
   issuer = self.convert_freaking_apostrophe(issuer)

System.Diagnostics.Process.Start can be used to print a document. Set UseShellExecute to True and set the Verb to "print".

You can also use

Cells.CurrentRegion

to give you a range representing the bounds of your data on the current active sheet

Msdn says on the topic

Returns a Range object that represents the current region. The current region is a range bounded by any combination of blank rows and blank columns. Read-only.

Then you can determine the column count via

Cells.CurrentRegion.Columns.Count

and the row count via

Cells.CurrentRegion.Rows.Count

This is what SSMS uses when you script using the DROP and CREATE option

IF EXISTS (SELECT *
           FROM   sys.objects
           WHERE  object_id = OBJECT_ID(N'[dbo].[foo]')
                  AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
  DROP FUNCTION [dbo].[foo]

GO 

This approach to deploying changes means that you need to recreate all permissions on the object so you might consider ALTER-ing if Exists instead.

You can get this easily using the map() function:

myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'}];

var found = $.map(myArray, function(val) {
    return val.id == 45 ? val.foo : null;
});

//found[0] == "bar";

Working example: http://jsfiddle.net/hunter/Pxaua/

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

You can nest your queries:

select * from (
    select bla
    from bla
    where bla
    order by finaldate desc
)
where rownum < 2

Support for schemas:

This is an updated version that amends the great answer from David, et al. Added is support for named schemas. It should be noted this may break if there's actually tables of the same name present within various schemas. Another improvement is the use of the official QuoteName() function.

SELECT 
    t.TABLE_CATALOG,
    t.TABLE_SCHEMA,
    t.TABLE_NAME,
    'create table '+QuoteName(t.TABLE_SCHEMA)+'.' + QuoteName(so.name) + ' (' + LEFT(o.List, Len(o.List)-1) + ');  ' 
        + CASE WHEN tc.Constraint_Name IS NULL THEN '' 
          ELSE

            + ' ADD CONSTRAINT ' + tc.Constraint_Name  + ' PRIMARY KEY ' + ' (' + LEFT(j.List, Len(j.List)-1) + ');  '

One detractor to the sql code above is if you test it using SSMS, long statements aren't easy to read. So, as per this helpful post, here's another version that's somewhat modified to be easier on the eyes after clicking the link of a cell in the grid. The results are more readily identifiable as nicely formatted CREATE TABLE statements for each table in the db.

Detracting factors:

It should be noted that I remain relatively unhappy with this due to the lack of support for indeces other than a primary key. It remains suitable for use as a mechanism for simple data export or replication.

It may be of interest that both Outlook and Outlook Express can generate these multipart image email formats, if you insert the image files using the Insert / Picture menu function.

Obviously the email type must be set to HTML (not plain text).

Any other method (e.g. drag/drop, or any command-line invocation) results in the image(s) being sent as an attachment.

If you then send such an email to yourself, you can see how it is formatted! :)

FWIW, I am looking for a standalone windows executable which does inline images from the command line mode, but there seem to be none. It's a path which many have gone up... One can do it with say Outlook Express, by passing it an appropriately formatted .eml file.

Check your <!DOCTYPE html>

I've noticed that if you miss out the <!DOCTYPE html> from the top of your HTML file, the dialog is shown centred within the document content not within the window, even if you specify position: { my: 'center', at: 'center', of: window}

EG: http://jsfiddle.net/npbx4561/ - Copy the content from the run window and remove the DocType. Save as HTML and run to see the problem.

Use a Comparator:

List<CustomObject> list = new ArrayList<CustomObject>();
Comparator<CustomObject> comparator = new Comparator<CustomObject>() {
    @Override
    public int compare(CustomObject left, CustomObject right) {
        return left.getId() - right.getId(); // use your logic
    }
};

Collections.sort(list, comparator); // use the comparator as much as u want
System.out.println(list);

Additionally, if CustomObjectimplements Comparable, then just use Collections.sort(list)

With JDK 8 the syntax is much simpler.

List<CustomObject> list = getCustomObjectList();
Collections.sort(list, (left, right) -> left.getId() - right.getId());
System.out.println(list);

Much simplier

List<CustomObject> list = getCustomObjectList();
list.sort((left, right) -> left.getId() - right.getId());
System.out.println(list);

Simplest

List<CustomObject> list = getCustomObjectList();
list.sort(Comparator.comparing(CustomObject::getId));
System.out.println(list);

Obviously the initial code can be used for JDK 8 too.

This function merges two dicts even if the keys in the two dictionaries are different:

def combine_dict(d1, d2):
    combined = {}
    for k in set(d1.keys()) | set(d2.keys()):
        combined[k] = tuple(d[k] for d in [d1, d2] if k in d)
    return combined

Example:

d1 = {
    'a': 1,
    'b': 2,
}
d2` = {
    'b': 'boat',
    'c': 'car',
}
combine_dict(d1, d2)
# Returns: {
#    'a': (1,),
#    'b': (2, 'boat'),
#    'c': ('car',)
# }

 ymin, ymax = axes.get_ylim()

If you are using the plt api directly, you can avoid calls to axes altogether:

def myplotfunction(title, values, errors, plot_file_name):

    # plot errorbars
    indices = range(0, len(values))
    fig = plt.figure()
    plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')

    plt.ylim([-0.5, len(values) - 0.5])
    plt.xlabel('My x-axis title')
    plt.ylabel('My y-axis title')

    # title
    plt.title(title)

    # save as file
    plt.savefig(plot_file_name)

   # close figure
    plt.close(fig)

It can be complicated to compute a diff in your head from the different sections in $MERGED and apply that. In my setup, meld helps by showing you these diffs visually, using:

[merge]
    tool = mymeld
    conflictstyle = diff3

[mergetool "mymeld"]
    cmd = meld --diff $BASE $REMOTE --diff $REMOTE $LOCAL --diff $LOCAL $MERGED

It looks strange but offers a very convenient work-flow, using three tabs:

1. in tab 1 you see (from left to right) the change that you should make in tab 2 to solve the merge conflict.

2. in the right side of tab 2 you apply the "change that you should make" and copy the entire file contents to the clipboard (using ctrl-a and ctrl-c).

3. in tab 3 replace the right side with the clipboard contents. If everything is correct, you will now see - from left to right - the same change as shown in tab 1 (but with different contexts). Save the changes made in this tab.

Notes:

• don't edit anything in tab 1
• don't save anything in tab 2 because that will produce annoying popups in tab 3

Anil was on the right track (his solution looks like it should work, I developed this solution independently of his). I still used the prepareForReuse: method to set the cell's selected to FALSE, then in the cellForItemAtIndexPath I check to see if the cell's index is in `collectionView.indexPathsForSelectedItems', if so, highlight it.

In the custom cell:

-(void)prepareForReuse {
    self.selected = FALSE;
}

In cellForItemAtIndexPath: to handle highlighting and dehighlighting reuse cells:

if ([collectionView.indexPathsForSelectedItems containsObject:indexPath]) {
    [collectionView selectItemAtIndexPath:indexPath animated:FALSE scrollPosition:UICollectionViewScrollPositionNone];
    // Select Cell
}
else {
    // Set cell to non-highlight
}

And then handle cell highlighting and dehighlighting in the didDeselectItemAtIndexPath: and didSelectItemAtIndexPath:

This works like a charm for me.

You cannot directly create a table stored as a sequence file and insert text into it. You must do this:

1. Create a table stored as text
2. Insert the text file into the text table
3. Do a CTAS to create the table stored as a sequence file.
4. Drop the text table if desired

Example:

CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;

CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;

DROP TABLE test_txt;

this should do:

//Main Class
public class SomeClass {

    //Sub-Class
    public static class AnotherClass {
        public enum MyEnum {
            VALUE_A, VALUE_B
        }    
        public MyEnum myEnum;
    }

    public void someMethod() { 
        AnotherClass.MyEnum enumExample = AnotherClass.MyEnum.VALUE_A; //...

        switch (enumExample) {
            case VALUE_A: { //<-- error on this line
            //..
            break;
            }
        }
    }
}

Because LINQ can do everything...:

string test = "key1=value1&key2=value2&key3=value3";
var count = test.Where(x => x == '&').Count();

Or if you like, you can use the Count overload that takes a predicate :

var count = test.Count(x => x == '&');

Using a null reference as the first operand to instanceof returns false.

See my answer here: Run only one task and handler from ansible playbook

It is possible to run separate role (from roles/ dir):

ansible -i stage.yml -m include_role -a name=create-os-user localhost

and separate task file:

ansible -i stage.yml -m include_tasks -a file=tasks/create-os-user.yml localhost

If you externalize tasks from role to root tasks/ directory (reuse is achieved by import_tasks: ../../../tasks/create-os-user.yml) you can run it independently from playbook/role.

I think this might be helpful:

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

See this link for more on the differences between a TextBlock and other Controls

There are a number of ways of achieving your result. If you're just wanting a solution for your case, use string multiplication as @Ant mentions. This is only going to work if each of your print statements prints the same string. Note that it works for multiplication of any length string (e.g. 'foo' * 20 works).

>>> print 'a' * 20
aaaaaaaaaaaaaaaaaaaa

If you want to do this in general, build up a string and then print it once. This will consume a bit of memory for the string, but only make a single call to print. Note that string concatenation using += is now linear in the size of the string you're concatenating so this will be fast.

>>> for i in xrange(20):
...     s += 'a'
... 
>>> print s
aaaaaaaaaaaaaaaaaaaa

Or you can do it more directly using sys.stdout.write(), which print is a wrapper around. This will write only the raw string you give it, without any formatting. Note that no newline is printed even at the end of the 20 as.

>>> import sys
>>> for i in xrange(20):
...     sys.stdout.write('a')
... 
aaaaaaaaaaaaaaaaaaaa>>> 

Python 3 changes the print statement into a print() function, which allows you to set an end parameter. You can use it in >=2.6 by importing from __future__. I'd avoid this in any serious 2.x code though, as it will be a little confusing for those who have never used 3.x. However, it should give you a taste of some of the goodness 3.x brings.

>>> from __future__ import print_function
>>> for i in xrange(20):
...     print('a', end='')
... 
aaaaaaaaaaaaaaaaaaaa>>> 

Just set the position of the div and you may have to set the z-index.

ex.

div#map-div {
    position: absolute;
    left: 10px;
    top: 10px;
}
div#cover-div {
    position:absolute;
    left:10px;
    top: 10px;
    z-index:3;
}

If you want you can use the recommended Bootstrap plugin to dynamize your custom file input: https://www.npmjs.com/package/bs-custom-file-input

This plugin can be use with or without jQuery and works with React an Angular

If you don't have an existing local branch, it is truly as simple as:

git fetch
git checkout <remote-branch-name>

For instance if you fetch and there is a new remote tracking branch called origin/feature/Main_Page, just do this:

git checkout feature/Main_Page

This creates a local branch with the same name as the remote branch, tracking that remote branch. If you have multiple remotes with the same branch name, you can use the less ambiguous:

git checkout -t <remote>/<remote-branch-name>

If you already made the local branch and don't want to delete it, see How do you make an existing Git branch track a remote branch?.

I believe there is a difference. Let's rename them so that we can talk about them more easily:

const     double PI1 = 3.141592653589793;
constexpr double PI2 = 3.141592653589793;

Both PI1 and PI2 are constant, meaning you can not modify them. However only PI2 is a compile-time constant. It shall be initialized at compile time. PI1 may be initialized at compile time or run time. Furthermore, only PI2 can be used in a context that requires a compile-time constant. For example:

constexpr double PI3 = PI1;  // error

but:

constexpr double PI3 = PI2;  // ok

and:

static_assert(PI1 == 3.141592653589793, "");  // error

but:

static_assert(PI2 == 3.141592653589793, "");  // ok

As to which you should use? Use whichever meets your needs. Do you want to ensure that you have a compile time constant that can be used in contexts where a compile-time constant is required? Do you want to be able to initialize it with a computation done at run time? Etc.

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

var out = new java.io.PrintWriter(new java.io.File(path), "UTF-8");
text = new java.lang.String( src || "" );
out.print(text);
out.flush();
out.close();

rem Just use "pause" at the end of the batch file.

One thing I found is the path of your image must be relative to wherever the notebook was originally loaded from. if you cd to a different directory, such as Pictures your Markdown path is still relative to the original loading directory.

Try just:

I'm using SQLServer 2008, but I have a development limitation: I cannot use a new driver for it, I have to use "com.microsoft.jdbc.sqlserver.SQLServerDriver" (I cannot use "com.microsoft.sqlserver.jdbc.SQLServerDriver").

That's why the solution conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS) threw a java.lang.AbstractMethodError for me. In this situation, a possible solution I found is the old one suggested by Microsoft: How To Retrieve @@IDENTITY Value Using JDBC

            String userName = "yourUser";
            String password = "yourPassword";

            System.out.println( "Trying to connect to: " + URL); 

            //Register JDBC Driver
            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();

            //Connect to SQL Server
            Connection con = null;
            con = DriverManager.getConnection(URL,userName,password);
            System.out.println("Successfully connected to server"); 

            //Create statement and Execute using either a stored procecure or batch statement
            CallableStatement callstmt = null;

            callstmt = con.prepareCall("INSERT INTO myIdentTable (col2) VALUES (?);SELECT @@IDENTITY");
            callstmt.setString(1, "testInputBatch");
            System.out.println("Batch statement successfully executed"); 
            callstmt.execute();

            int iUpdCount = callstmt.getUpdateCount();
            boolean bMoreResults = true;
            ResultSet rs = null;
            int myIdentVal = -1; //to store the @@IDENTITY

            //While there are still more results or update counts
            //available, continue processing resultsets
            while (bMoreResults || iUpdCount!=-1)
            {           
                //NOTE: in order for output parameters to be available,
                //all resultsets must be processed

                rs = callstmt.getResultSet();                   

                //if rs is not null, we know we can get the results from the SELECT @@IDENTITY
                if (rs != null)
                {
                    rs.next();
                    myIdentVal = rs.getInt(1);
                }                   

                //Do something with the results here (not shown)

                //get the next resultset, if there is one
                //this call also implicitly closes the previously obtained ResultSet
                bMoreResults = callstmt.getMoreResults();
                iUpdCount = callstmt.getUpdateCount();
            }

            System.out.println( "@@IDENTITY is: " + myIdentVal);        

            //Close statement and connection 
            callstmt.close();
            con.close();
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }

        try
        {
            System.out.println("Press any key to quit...");
            System.in.read();
        }
        catch (Exception e)
        {
        }
    }
}

This solution worked for me!

I hope this helps!

This is going to work :

In [1]: import torch

In [2]: torch.cuda.current_device()
Out[2]: 0

In [3]: torch.cuda.device(0)
Out[3]: <torch.cuda.device at 0x7efce0b03be0>

In [4]: torch.cuda.device_count()
Out[4]: 1

In [5]: torch.cuda.get_device_name(0)
Out[5]: 'GeForce GTX 950M'

In [6]: torch.cuda.is_available()
Out[6]: True

This tells me the GPU GeForce GTX 950M is being used by PyTorch.

If you're using some plugin which takes string and use construct Regex to create Regex Object i:e new RegExp()

Than Below string will work

'^\\S*$'

It's same regex @Bergi mentioned just the string version for new RegExp constructor

I almost had this problem and it was very deceiving. I am providing an answer in case someone winds up in my same position.

1. I thought I had this problem
2. But, I was using return false and javascript:void(0);
3. Then a distinct difference in problem kept surfacing:
4. I realized it's not going ALL the way to the top - and my problem zone was near the bottom of the page so this jump was strange and annoying.
5. I realized I was using fadeIn() [jQuery library], which for a short time my content was display:none
6. And then my content extended the reach of the page! Causing what looks like a jump!
7. Using visibility hidden toggles now..

Hope this helps the person stuck with jumps!!

Long story short you have to use atoi()

ed:

If you are interested in doing this the right way :

char szNos[] = "12345";
char *pNext;
long output;
output = strtol (szNos, &pNext, 10); // input, ptr to next char in szNos (null here), base 

Best performance method

sed '5q;d' file

Because sed stops reading any lines after the 5th one

Update experiment from Mr. Roger Dueck

I installed wcanadian-insane (6.6MB) and compared sed -n 1p /usr/share/dict/words and sed '1q;d' /usr/share/dict/words using the time command; the first took 0.043s, the second only 0.002s, so using 'q' is definitely a performance improvement!

simple write in your bat file

@cmd

or

@cmd /k "command1&command2"

I got this error when I tried to install a Xamarin project built against Android N preview on a phone running api v23. Solution is to not do that.

You can compare both approaches for the same data:

def myGeneratorList(n):
    for i in range(n):
        yield i

def myIterableList(n):
    ll = n*[None]
    for i in range(n):
        ll[i] = i
    return ll

# Same values
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)
for i1, i2 in zip(ll1, ll2):
    print("{} {}".format(i1, i2))

# Generator can only be read once
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)

print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))

# Generator can be read several times if converted into iterable
ll1 = list(myGeneratorList(10))
ll2 = myIterableList(10)

print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))

Besides, if you check the memory footprint, the generator takes much less memory as it doesn't need to store all the values in memory at the same time.

You can use Localstorage

1- Add dependency to pubspec.yaml (Change the version based on the last)

dependencies:
  ...
  localstorage: ^3.0.0

2- Then run the following command

flutter packages get

3- import the localstorage :

import 'package:localstorage/localstorage.dart';

4- create an instance

class MainApp extends StatelessWidget {
  final LocalStorage storage = new LocalStorage('localstorage_app');
  ...
}

Add item to lcoalstorage :

void addItemsToLocalStorage() {
  storage.setItem('name', 'Abolfazl');
  storage.setItem('family', 'Roshanzamir');

  final info = json.encode({'name': 'Darush', 'family': 'Roshanzami'});
  storage.setItem('info', info);
}

Get an item from lcoalstorage:

void getitemFromLocalStorage() {
  final name = storage.getItem('name'); // Abolfazl
  final family = storage.getItem('family'); // Roshanzamir
  
  Map<String, dynamic> info = json.decode(storage.getItem('info'));
  final info_name=info['name'];
  final info_family=info['family'];
}

Delete an item from localstorage :

void removeItemFromLocalStorage() {
  storage.deleteItem('name');
  storage.deleteItem('family');
  storage.deleteItem('info');
}

One thing that I'm surprised hasn't been mentioned yet is that implementing Runnable makes your class more flexible.

If you extend thread then the action you're doing is always going to be in a thread. However, if you implement Runnable it doesn't have to be. You can run it in a thread, or pass it to some kind of executor service, or just pass it around as a task within a single threaded application (maybe to be run at a later time, but within the same thread). The options are a lot more open if you just use Runnable than if you bind yourself to Thread.

Note that tr can only handle plain ASCII, making any tr-based solution fail when facing international characters.

Same goes for the bash 4 based ${x,,} solution.

The awk tool, on the other hand, properly supports even UTF-8 / multibyte input.

y="HELLO"
val=$(echo "$y" | awk '{print tolower($0)}')
string="$val world"

The use case that lead me to search for this is the following

def setfrom(self,f):
    """Set from iterable f"""
    fi = iter(f)
    for i in range(self.n):
        try:
            x = next(fi)
        except StopIteration:
            fi = iter(f)
            x = next(fi)
        self.a[i] = x 

where hasnext() is available, one could do

def setfrom(self,f):
    """Set from iterable f"""
    fi = iter(f)
    for i in range(self.n):
        if not hasnext(fi):
            fi = iter(f) # restart
        self.a[i] = next(fi)

which to me is cleaner. Obviously you can work around issues by defining utility classes, but what then happens is you have a proliferation of twenty-odd different almost-equivalent workarounds each with their quirks, and if you wish to reuse code that uses different workarounds, you have to either have multiple near-equivalent in your single application, or go around picking through and rewriting code to use the same approach. The 'do it once and do it well' maxim fails badly.

Furthermore, the iterator itself needs to have an internal 'hasnext' check to run to see if it needs to raise an exception. This internal check is then hidden so that it needs to be tested by trying to get an item, catching the exception and running the handler if thrown. This is unnecessary hiding IMO.

For those with a sudo-less CocoaPods installation (i.e., you do not want to grant RubyGems admin privileges), you don't need the sudo command to update your CocoaPods installation:

gem install cocoapods

You can find out where the CocoaPods gem is installed with:

gem which cocoapods

If this is within your home directory, you should definitely run gem install cocoapods without using sudo.

Finally, to check which CocoaPods you are currently running type:

pod --version

I try to write working code example, I test it and everything works.

Hare is code:

HTML:

<input type="file" class="attachment_input" name="file" onchange="checkFileSize(this, @Model.MaxSize.ToString(),@Html.Raw(Json.Encode(Model.FileExtensionsList)))" />

Javascript:

 //function for check attachment size and extention match
function checkFileSize(element, maxSize, extentionsArray) {
    var val = $(element).val(); //get file value

    var ext = val.substring(val.lastIndexOf('.') + 1).toLowerCase(); // get file extention 
    if ($.inArray(ext, extentionsArray) == -1) {
        alert('false extension!');
    }

    var fileSize = ($(element)[0].files[0].size / 1024 / 1024); //size in MB
    if (fileSize > maxSize) {
        alert("Large file");// if Maxsize from Model > real file size alert this
    }
}

The Symfony project tries to keep its HTTP methods joined up with CRUD methods, and their list associates them as follows:

• GET Retrieve the resource from the server
• POST Create a resource on the server
• PUT Update the resource on the server
• DELETE Delete the resource from the server

It's worth noting that, as they say on that page, "In reality, many modern browsers don't support the PUT and DELETE methods."

From what I remember, Symfony "fakes" PUT and DELETE for those browsers that don't support them when generating its forms, in order to try to be as close to using the theoretically-correct HTTP method even when a browser doesn't support it.

Since the accepted BufferedInputStream#read isn't guaranteed to read everything, rather than keeping track of the buffer sizes myself, I used this approach:

    byte bytes[] = new byte[(int) file.length()];
    BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file));
    DataInputStream dis = new DataInputStream(bis);
    dis.readFully(bytes);

Blocks until a full read is complete, and doesn't require extra imports.

swift 5 and above

case 1 : using with Navigation controller

self.navigationController?.popViewController(animated: true)

case 2 : using with present view controller

self.dismiss(animated: true, completion: nil)

Or create a function that creates an element including attributes from parameters

function elemCreate(elType){
  var element = document.createElement(elType);
  if (arguments.length>1){
    var props = [].slice.call(arguments,1), key = props.shift();
    while (key){ 
      element.setAttribute(key,props.shift());
      key = props.shift();
    }
  }
  return element;
}
// usage
var img = elemCreate('img',
            'width','100',
            'height','100',
            'src','http://example.com/something.jpeg');

FYI: height/width='100%' would not work using attributes. For a height/width of 100% you need the elements style.height/style.width

you probably forgot to use "".

For exemple:

$_array[text] = $_var;

change to:

$_array["text"] = $_var;

In Java its Webelement.getText() . Not sure about python.

MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.

To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED.

You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.

Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:

"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*

As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.

I got this problem because I uninstalled VS 2012, I don't want to reinstall it back, so I downloaded the AspNetMVC4Setup.exe from Microsoft.com and fixed my problem.

In addition to slhck, this is what worked for me (mac).

To check where your sdk is located.

1. Open Android studio and go to:

File -> Project Structure -> Sdk location

2. Copy the path.

3. Create the hidden .bash_profile in your home.

4. (open it with vim, or open -e) with the following:

export PATH=/Users/<Your session name>/Library/Android/sdk/platform-tools:/Users/<Your session name>/Library/Android/sdk/tools:$PATH

5. Then simply use this in your terminal: . ~/.bash_profile

SO post on how to find adb devices

It is not possible because they are executed in different environments (JSP at server side, JavaScript at client side). So they are not executed in the sequence you see in your code.

var val1 = document.getElementById('userName').value; 

<c:set var="user" value=""/>  // how do i set val1 here? 

Here JSTL code is executed at server side and the server sees the JavaScript/Html codes as simple texts. The generated contents from JSTL code (if any) will be rendered in the resulting HTML along with your other JavaScript/HTML codes. Now the browser renders HTML along with executing the Javascript codes. Now remember there is no JSTL code available for the browser.

Now for example,

<script type="text/javascript">
<c:set var="message" value="Hello"/> 
var message = '<c:out value="${message}"/>';
</script>

Now for the browser, this content is rendered,

<script type="text/javascript">
var message = 'Hello';
</script>

Hope this helps.

Correct and more clear way is :

<div style={{"font-size" : "10px", "height" : "100px", "width" : "100%"}}> My inline Style </div>

It is made more simple by following approach :

// JS
const styleObject = {
      "font-size" : "10px",
      "height" : "100px",
      "width" : "100%"
}

// HTML    
<div style={styleObject}> My inline Style </div>

Inline style attribute expects object. Hence its written in {}, and it becomes double {{}} as one is for default react standards.

You can use continue

if condition:
    continue
else:
    #do something

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

Either manually, like

var str = "www.test.com",
    rmv = "www.";

str = str.slice( str.indexOf( rmv ) + rmv.length );

or just use .replace():

str = str.replace( rmv, '' );

urllib has been split up in Python 3.

The urllib.urlencode() function is now urllib.parse.urlencode(),

the urllib.urlopen() function is now urllib.request.urlopen().

On Windows you can use CRT debug heap.

Is there any standard or procedure one should follow to ensure there is no memory leak in the program.

Yeah, don't use manual memory management (if you ever call delete or delete[] manually, then you're doing it wrong). Use RAII and smart pointers, limit heap allocations to the absolute minimum (most of the time, automatic variables will suffice).

A regular expression can be used to offer more control over the whitespace characters that are combined.

To match unicode whitespace:

import re

_RE_COMBINE_WHITESPACE = re.compile(r"\s+")

my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str).strip()

To match ASCII whitespace only:

import re

_RE_COMBINE_WHITESPACE = re.compile(r"(?a:\s+)")
_RE_STRIP_WHITESPACE = re.compile(r"(?a:^\s+|\s+$)")

my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str)
my_str = _RE_STRIP_WHITESPACE.sub("", my_str)

Matching only ASCII whitespace is sometimes essential for keeping control characters such as x0b, x0c, x1c, x1d, x1e, x1f.

Reference:

About \s:

For Unicode (str) patterns: Matches Unicode whitespace characters (which includes [ \t\n\r\f\v], and also many other characters, for example the non-breaking spaces mandated by typography rules in many languages). If the ASCII flag is used, only [ \t\n\r\f\v] is matched.

About re.ASCII:

Make \w, \W, \b, \B, \d, \D, \s and \S perform ASCII-only matching instead of full Unicode matching. This is only meaningful for Unicode patterns, and is ignored for byte patterns. Corresponds to the inline flag (?a).

strip() will remote any leading and trailing whitespaces.

Prescription

One simple rewrite of the command in the question is:

grep "word1" logs | grep "word2"

The first grep finds lines with 'word1' from the file 'logs' and then feeds those into the second grep which looks for lines containing 'word2'.

However, it isn't necessary to use two commands like that. You could use extended grep (grep -E or egrep):

grep -E 'word1.*word2|word2.*word1' logs

If you know that 'word1' will precede 'word2' on the line, you don't even need the alternatives and regular grep would do:

grep 'word1.*word2' logs

The 'one command' variants have the advantage that there is only one process running, and so the lines containing 'word1' do not have to be passed via a pipe to the second process. How much this matters depends on how big the data file is and how many lines match 'word1'. If the file is small, performance isn't likely to be an issue and running two commands is fine. If the file is big but only a few lines contain 'word1', there isn't going to be much data passed on the pipe and using two command is fine. However, if the file is huge and 'word1' occurs frequently, then you may be passing significant data down the pipe where a single command avoids that overhead. Against that, the regex is more complex; you might need to benchmark it to find out what's best — but only if performance really matters. If you run two commands, you should aim to select the less frequently occurring word in the first grep to minimize the amount of data processed by the second.

Diagnosis

The initial script is:

grep -c "word1" | grep -r "word2" logs

This is an odd command sequence. The first grep is going to count the number of occurrences of 'word1' on its standard input, and print that number on its standard output. Until you indicate EOF (e.g. by typing Control-D), it will sit there, waiting for you to type something. The second grep does a recursive search for 'word2' in the files underneath directory logs (or, if it is a file, in the file logs). Or, in my case, it will fail since there's neither a file nor a directory called logs where I'm running the pipeline. Note that the second grep doesn't read its standard input at all, so the pipe is superfluous.

With Bash, the parent shell waits until all the processes in the pipeline have exited, so it sits around waiting for the grep -c to finish, which it won't do until you indicate EOF. Hence, your code seems to get stuck. With Heirloom Shell, the second grep completes and exits, and the shell prompts again. Now you have two processes running, the first grep and the shell, and they are both trying to read from the keyboard, and it is not determinate which one gets any given line of input (or any given EOF indication).

Note that even if you typed data as input to the first grep, you would only get any lines that contain 'word2' shown on the output.

Footnote:

At one time, the answer used:

grep -E 'word1.*word2|word2.*word1' "$@"
grep 'word1.*word2' "$@"

This triggered the comments below.

In any case, you can override height with max-height.

Your session status are set once you start a session, and by default, take the current GLOBAL value.

If you disconnected after you did SET @@GLOBAL.wait_timeout=300, then subsequently reconnected, you'd see

SHOW SESSION VARIABLES LIKE "%wait%";

Result: 300

Similarly, at any time, if you did

mysql> SET session wait_timeout=300;

You'd get

mysql> SHOW SESSION VARIABLES LIKE 'wait_timeout';

+---------------+-------+
| Variable_name | Value |

Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.

 <div class="circle" [style.background]="color">

Another convoluted answer which should technically work and is ok for a small number of data points is to plot all your data points as 1 series in order to get your connecting line. Then plot each point as its own series. Then format data labels to display series name for each of the individual data points.

In short it works ok for a small data set or just key points from a data set.

Adding to Gaby's post, my jdbc getTables() for Oracle 10g requires all caps to work:

Otherwise I would get an exception:

    refreshAlert .dismissViewControllerAnimated(true, completion: nil)


}))

presentViewController(refreshAlert, animated: true, completion: nil)

I don't think any of the current answers really do what you said you want. (Correction: I now see that @Gareth Latty / @Lattyware has incorporated my answer into his own as an "Edit" near the end.)

Anyway, here's my take:

Say these are the tab-separated values in your input file:

1   2   3   4   5
6   7   8   9   10
11  12  13  14  15
16  17  18  19  20

then this:

with open("tab-separated-values.txt") as inp:
    print( list(zip(*(line.strip().split('\t') for line in inp))) )

would produce the following:

[('1', '6', '11', '16'), 
 ('2', '7', '12', '17'), 
 ('3', '8', '13', '18'), 
 ('4', '9', '14', '19'), 
 ('5', '10', '15', '20')]

As you can see, it put the k-th element of each row into the k-th array.

Yet another tip that worked for me. Run the command:

$ mysql_install_db

Change URL behavior to "Dynamic".

You can change the color of EditText programmatically just using this line of code easily:

edittext.setBackgroundTintList(ColorStateList.valueOf(yourcolor));

Try this

  height:100px;_x000D_
  background:red;_x000D_

DEMO

You forgot to call startActivity. It should look like this:

Intent intent = new Intent(Intent.ACTION_CALL);

intent.setData(Uri.parse("tel:" + bundle.getString("mobilePhone")));
context.startActivity(intent);

An intent by itself is simply an object that describes something. It doesn't do anything.

Don't forget to add the relevant permission to your manifest:

<uses-permission android:name="android.permission.CALL_PHONE" />

All standard implementations of java.util.List already implement java.io.Serializable.

So even though java.util.List itself is not a subtype of java.io.Serializable, it should be safe to cast the list to Serializable, as long as you know it's one of the standard implementations like ArrayList or LinkedList.

If you're not sure, then copy the list first (using something like new ArrayList(myList)), then you know it's serializable.

$_POST is an array in itsself you don't need to make an array out of it. What you did is nest the $_POST array inside a new array. This is why you print Array. Change it to:

foreach ($_POST as $key => $value) {

  echo "<p>".$key."</p>";
  echo "<p>".$value."</p>";
  echo "<hr />";

} 

Here's a super simple implementation that allows use of the for each construct and relies only on C++14 std library:

    template<class T>
    struct iterator_range
    {
        T beginning, ending;
        iterator_range(T beginning, T ending) : beginning(beginning), ending(ending) {}

        T begin() const { return beginning; }
        T end() const { return ending; }
    };

}

auto backwards(T & collection)
{
    using namespace std;
    return Details::iterator_range(rbegin(collection), rend(collection));
}

This works with things that supply an rbegin() and rend(), as well as with static arrays.

std::vector<int> collection{ 5, 9, 15, 22 };
for (auto e : backwards(collection))
    ;

long values[] = { 3, 6, 9, 12 };
for (auto e : backwards(values))
    ;

According to the C99 spec,

• NULL expands to a null pointer constant, which is not required to be, but typically is of type void *
• '\0' is a character constant; character constants are of type int, so it's equivalen to plain 0
• "\0" is a null-terminated string literal and equivalent to the compound literal (char [2]){ 0, 0 }

NULL, '\0' and 0 are all null pointer constants, so they'll all yield null pointers on conversion, whereas "\0" yields a non-null char * (which should be treated as const as modification is undefined); as this pointer may be different for each occurence of the literal, it can't be used as sentinel value.

Although you may use any integer constant expression of value 0 as a null pointer constant (eg '\0' or sizeof foo - sizeof foo + (int)0.0), you should use NULL to make your intentions clear.

Dherik : I'm not sure about what you say, when you don't use fetch the result will be of type : List<Object[ ]> which means a list of Object tables and not a list of Employee.

Object[0] refers an Employee entity 
Object[1] refers a Departement entity 

When you use fetch, there is just one select and the result is the list of Employee List<Employee> containing the list of departements. It overrides the lazy declaration of the entity.

A special case is when trying to assess if a boolean value is nil:

false.present? == false
false.blank? == true
false.nil? == false

In this case the recommendation would be to use .nil?

A "Broken Pipe" error occurs when you try to write to a pipe that has been closed on the other end. Since the code you've shown doesn't involve any pipes directly, I suspect you're doing something outside of Python to redirect the standard output of the Python interpreter to somewhere else. This could happen if you're running a script like this:

python foo.py | someothercommand

The issue you have is that someothercommand is exiting without reading everything available on its standard input. This causes your write (via print) to fail at some point.

I was able to reproduce the error with the following command on a Linux system:

python -c 'for i in range(1000): print i' | less

If I close the less pager without scrolling through all of its input (1000 lines), Python exits with the same IOError you have reported.

With jQuery:

function isHTML(str) {
  return /^<.*?>$/.test(str) && !!$(str)[0];
}

Just as reference let me quote the osxfuse FAQ

4.8. How should I unmount my "FUSE for OS X" file system? I cannot find the fusermount program anywhere.

Just use the standard umount command in OS X. You do not need the Linux-specific fusermount with "FUSE for OS X".

As mentioned above, either diskutil unmount or umount should work

brew install python3
brew unlink python

then I installed python 3.6.5 using above link

As promised, here is my Cairo version. I scripted it with Lua, using lfs to walk the directories. I love these little challenges, as they allow me to explore APIs I wanted to dig for quite some time...
lfs and LuaCairo are both cross-platform, so it should work on other systems (tested on French WinXP Pro SP3).

I made a first version drawing file names as I walked the tree. Advantage: no memory overhead. Inconvenience: I have to specify the image size beforehand, so listings are likely to be cut off.

So I made this version, first walking the directory tree, storing it in a Lua table. Then, knowing the number of files, creating the canvas to fit (at least vertically) and drawing the names.
You can easily switch between PNG rendering and SVG one. Problem with the latter: Cairo generates it at low level, drawing the letters instead of using SVG's text capability. Well, at least, it guarantees accurate rending even on systems without the font. But the files are bigger... Not really a problem if you compress it after, to have a .svgz file.
Or it shouldn't be too hard to generate the SVG directly, I used Lua to generate SVG in the past.

Of course, you can change the styles. I didn't draw the connection lines, I didn't saw it as necessary. I might add them optionally later.

Both are poles on two different axis:

• strongly typed vs. weakly typed
• statically typed vs. dynamically typed

Strongly typed means, a will not be automatically converted from one type to another. Weakly typed is the opposite: Perl can use a string like "123" in a numeric context, by automatically converting it into the int 123. A strongly typed language like python will not do this.

Statically typed means, the compiler figures out the type of each variable at compile time. Dynamically typed languages only figure out the types of variables at runtime.

You can use the subscript operator

l[4] = -1

Another important feature of the LEA instruction is that it does not alter the condition codes such as CF and ZF, while computing the address by arithmetic instructions like ADD or MUL does. This feature decreases the level of dependency among instructions and thus makes room for further optimization by the compiler or hardware scheduler.

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

You are using the same connection for the DataReader and the ExecuteNonQuery. This is not supported, according to MSDN:

Note that while a DataReader is open, the Connection is in use exclusively by that DataReader. You cannot execute any commands for the Connection, including creating another DataReader, until the original DataReader is closed.

This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.

Have a look at jQuery, a cross-browser library that will make your life a lot easier.

var msg = 'abc';
$('#msg').val(msg);
$('#sp_100').attr('checked', 'checked');

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

On Mac/Linux, you'll need to enter the following entry in your ~/.bashrc:

export PATH="/usr/lib/google-cloud-sdk/bin:$PATH"

Try this

box-sizing: border-box;

The :: instead of REM was preferably used in the days that computers weren't very fast. REM'ed line are read and then ingnored. ::'ed line are ignored all the way. This could speed up your code in "the old days". Further more after a REM you need a space, after :: you don't.

And as said in the first comment: you can add info to any line you feel the need to

SET DATETIME=%DTS:~0,8%-%DTS:~8,6% ::Makes YYYYMMDD-HHMMSS

As for the skipping of parts. Putting REM in front of every line can be rather time consuming. As mentioned using GOTO to skip parts is an easy way to skip large pieces of code. Be sure to set a :LABEL at the point you want the code to continue.

SOME CODE

GOTO LABEL  ::REM OUT THIS LINE TO EXECUTE THE CODE BETWEEN THIS GOTO AND :LABEL

SOME CODE TO SKIP
.
LAST LINE OF CODE TO SKIP

:LABEL
CODE TO EXECUTE

Why not having something simpler?

Just call Request.Path, it will return a String Separated by the "/"

and then you can use .Split('/')[1] to get the Controller Name.

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n will work.

If you use anything else you will cause issues with cut and paste on Windows platforms.

The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.

Interestingly, in spite of the Unix line end convention being \n, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n. Yes, it may not make a lot of sense, but that's history and evolving standards for you!

Json.NET does this...

string json = @"{""key1"":""value1"",""key2"":""value2""}";

var values = JsonConvert.DeserializeObject<Dictionary<string, string>>(json);

More examples: Serializing Collections with Json.NET

after looking for a similar solution and not finding anything flexible enough, I decided to write my own function for it. It allows you to have as many bars per group as you wish and specify both the width of a group as well as the individual widths of the bars within the groups.

Enjoy:

from matplotlib import pyplot as plt


def bar_plot(ax, data, colors=None, total_width=0.8, single_width=1, legend=True):
    """Draws a bar plot with multiple bars per data point.

    Parameters
    ----------
    ax : matplotlib.pyplot.axis
        The axis we want to draw our plot on.

    data: dictionary
        A dictionary containing the data we want to plot. Keys are the names of the
        data, the items is a list of the values.

        Example:
        data = {
            "x":[1,2,3],
            "y":[1,2,3],
            "z":[1,2,3],
        }

    colors : array-like, optional
        A list of colors which are used for the bars. If None, the colors
        will be the standard matplotlib color cyle. (default: None)

    total_width : float, optional, default: 0.8
        The width of a bar group. 0.8 means that 80% of the x-axis is covered
        by bars and 20% will be spaces between the bars.

    single_width: float, optional, default: 1
        The relative width of a single bar within a group. 1 means the bars
        will touch eachother within a group, values less than 1 will make
        these bars thinner.

    legend: bool, optional, default: True
        If this is set to true, a legend will be added to the axis.
    """

    # Check if colors where provided, otherwhise use the default color cycle
    if colors is None:
        colors = plt.rcParams['axes.prop_cycle'].by_key()['color']

    # Number of bars per group
    n_bars = len(data)

    # The width of a single bar
    bar_width = total_width / n_bars

    # List containing handles for the drawn bars, used for the legend
    bars = []

    # Iterate over all data
    for i, (name, values) in enumerate(data.items()):
        # The offset in x direction of that bar
        x_offset = (i - n_bars / 2) * bar_width + bar_width / 2

        # Draw a bar for every value of that type
        for x, y in enumerate(values):
            bar = ax.bar(x + x_offset, y, width=bar_width * single_width, color=colors[i % len(colors)])

        # Add a handle to the last drawn bar, which we'll need for the legend
        bars.append(bar[0])

    # Draw legend if we need
    if legend:
        ax.legend(bars, data.keys())


if __name__ == "__main__":
    # Usage example:
    data = {
        "a": [1, 2, 3, 2, 1],
        "b": [2, 3, 4, 3, 1],
        "c": [3, 2, 1, 4, 2],
        "d": [5, 9, 2, 1, 8],
        "e": [1, 3, 2, 2, 3],
        "f": [4, 3, 1, 1, 4],
    }

    fig, ax = plt.subplots()
    bar_plot(ax, data, total_width=.8, single_width=.9)
    plt.show()

Output:

Your code would be like this:

int *p = (int *)0x28ff44;

int needs to be the type of the object that you are referencing or it can be void.

But be careful so that you don't try to access something that doesn't belong to your program.

I know this has been answered, but I'd like to add my own answer:

using (var reader = new StringReader(multiLineString))
{
    for (string line = reader.ReadLine(); line != null; line = reader.ReadLine())
    {
        // Do something with the line
    }
}

DSM's and Tadeck's answers answer your question directly.

In my scripts I often use the convenient dict.pop() to deal with optional, and additional arguments. Here's an example of a simple print() wrapper:

def my_print(*args, **kwargs):
    prefix = kwargs.pop('prefix', '')
    print(prefix, *args, **kwargs)

Then:

>>> my_print('eggs')
 eggs
>>> my_print('eggs', prefix='spam')
spam eggs

As you can see, if prefix is not contained in kwargs, then the default '' (empty string) is being stored in the local prefix variable. If it is given, then its value is being used.

This is generally a compact and readable recipe for writing wrappers for any kind of function: Always just pass-through arguments you don't understand, and don't even know if they exist. If you always pass through *args and **kwargs you make your code slower, and requires a bit more typing, but if interfaces of the called function (in this case print) changes, you don't need to change your code. This approach reduces development time while supporting all interface changes.

More easy to understand (What is Lambda actually doing):

ls2=[[0,1,'f'],[4,2,'t'],[9,4,'afsd']]
def thirdItem(ls):
    #return the third item of the list
    return ls[2]
#Sort according to what the thirdItem function return 
ls2.sort(key=thirdItem)

Wouldn't lambdaj's project function do what you are looking for?

It'll look something like this:

List<UserDTO> userNDtos = project(users, UserDTO.class, on(User.class).getUserName(), on(User.class).getFullName(), .....);

(Define the constructor for UserDTO accordingly...)

SIMPLE SOLUTION

I wanted to support apps pre api 23 and instead of using checkSelfPermission I used a try / catch

try {
   location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
} catch (SecurityException e) {
   dialogGPS(this.getContext()); // lets the user know there is a problem with the gps
}

This is a simple PHP script to return male female and user id as json value will be any random value as you call the script json.php .

Hope this help thanks

$myObj=new \stdClass();
$myObj->user_id = rand(0, 10);
$myObj->male = rand(0, 5);
$myObj->female = rand(0, 5);
$myJSON = json_encode($myObj);
echo $myJSON;

To the OP or anyone currently interested, here's the section of code that's worked for me with firefox currently:

opt = webdriver.FirefoxOptions()
opt.add_argument('-headless')
ffox_driver = webdriver.Firefox(executable_path='\path\to\geckodriver', options=opt)

You can also use package plyr, which is somehow more versatile:

library(plyr)

ddply(d, .(Name), summarize,  Rate1=mean(Rate1), Rate2=mean(Rate2))

  Name    Rate1    Rate2
1 Aira 16.33333 47.00000
2  Ben 31.33333 50.33333
3  Cat 44.66667 54.00000

You can run this command in Terminal:

react-native --version

This will give react-native CLI version

Or check in package.json under

"dependencies": {
    "react": "16.11.0",
    "react-native": "0.62.2",
}

You want your UI updates to happen in the already-existent UI thread.

The best way is to use a Handler that uses postDelayed to run a Runnable after a delay (each run schedules the next); clear the callback with removeCallbacks.

You're already looking in the right place, so look at it again, perhaps clarify why that code sample isn't what you want. (See also the identical article at Updating the UI from a Timer).

Both rebase (and cherry-pick) and merge have their advantages and disadvantages. I argue for merge here, but it's worth understanding both. (Look here for an alternate, well-argued answer enumerating cases where rebase is preferred.)

merge is preferred over cherry-pick and rebase for a couple of reasons.

1. Robustness. The SHA1 identifier of a commit identifies it not just in and of itself but also in relation to all other commits that precede it. This offers you a guarantee that the state of the repository at a given SHA1 is identical across all clones. There is (in theory) no chance that someone has done what looks like the same change but is actually corrupting or hijacking your repository. You can cherry-pick in individual changes and they are likely the same, but you have no guarantee. (As a minor secondary issue the new cherry-picked commits will take up extra space if someone else cherry-picks in the same commit again, as they will both be present in the history even if your working copies end up being identical.)
2. Ease of use. People tend to understand the merge workflow fairly easily. rebase tends to be considered more advanced. It's best to understand both, but people who do not want to be experts in version control (which in my experience has included many colleagues who are damn good at what they do, but don't want to spend the extra time) have an easier time just merging.

Even with a merge-heavy workflow rebase and cherry-pick are still useful for particular cases:

1. One downside to merge is cluttered history. rebase prevents a long series of commits from being scattered about in your history, as they would be if you periodically merged in others' changes. That is in fact its main purpose as I use it. What you want to be very careful of, is never to rebase code that you have shared with other repositories. Once a commit is pushed someone else might have committed on top of it, and rebasing will at best cause the kind of duplication discussed above. At worst you can end up with a very confused repository and subtle errors it will take you a long time to ferret out.
2. cherry-pick is useful for sampling out a small subset of changes from a topic branch you've basically decided to discard, but realized there are a couple of useful pieces on.

As for preferring merging many changes over one: it's just a lot simpler. It can get very tedious to do merges of individual changesets once you start having a lot of them. The merge resolution in git (and in Mercurial, and in Bazaar) is very very good. You won't run into major problems merging even long branches most of the time. I generally merge everything all at once and only if I get a large number of conflicts do I back up and re-run the merge piecemeal. Even then I do it in large chunks. As a very real example I had a colleague who had 3 months worth of changes to merge, and got some 9000 conflicts in 250000 line code-base. What we did to fix is do the merge one month's worth at a time: conflicts do not build up linearly, and doing it in pieces results in far fewer than 9000 conflicts. It was still a lot of work, but not as much as trying to do it one commit at a time.

I recently came to a similar situation where I needed to register a handler for an event only once. I found that you can safely unregister first, and then register again, even if the handler is not registered at all:

myClass.MyEvent -= MyHandler;
myClass.MyEvent += MyHandler;

Note that doing this every time you register your handler will ensure that your handler is registered only once. Sounds like a pretty good practice to me :)

As of now, the Go compiler generates identical code in both cases, so it is a matter of taste. GCCGo does generate different code, but barely anyone uses it so I wouldn't worry about that.

In my case (AWS EC2 instance, Ubuntu) helped:

$ sudo mkdir -p /data/db/
$ sudo chown `USERNAME` /data/db

And after that everything worked fine.

You need to catch the return value.

The DateTime.AddDays method returns an object who's value is the sum of the date and time of the instance and the added value.

endDate = endDate.AddDays(addedDays);

Unchecked the content type in Postman and postman automatically detect the content type based on your input in the run time.

You are missing the selector in the .on function:

.on(eventType, selector, function)

This selector is very important!

http://api.jquery.com/on/

If new HTML is being injected into the page, select the elements and attach event handlers after the new HTML is placed into the page. Or, use delegated events to attach an event handler

See jQuery 1.9 .live() is not a function for more details.

...this is obviously performing a 'string' comparison

No - if the date/time format matches the supported format, MySQL performs implicit conversion to convert the value to a DATETIME, based on the column it is being compared to. Same thing happens with:

WHERE int_column = '1'

...where the string value of "1" is converted to an INTeger because int_column's data type is INT, not CHAR/VARCHAR/TEXT.

If you want to explicitly convert the string to a DATETIME, the STR_TO_DATE function would be the best choice:

WHERE expires_at <= STR_TO_DATE('2010-10-15 10:00:00', '%Y-%m-%d %H:%i:%s')

**#Method 1:**Try to put your jquery code in a separate js file.

Now register that script in functions.php file.

function add_my_script() {
    wp_enqueue_script(
      'custom-script', get_template_directory_uri() . '/js/your-script-name.js', 
        array('jquery') 
    );
}
add_action( 'wp_enqueue_scripts', 'add_my_script' );

Now you are done.

Registering script in functions has it benefits as it comes in <head> section when page loads thus it is a part of header.php always. So you don't have to repeat your code each time you write a new html content.

#Method 2: put the script code inside the page body under <script> tag. Then you don't have to register it in functions.

public void getMyLocation() {
        // create class object
        gps = new GPSTracker(HomeActivity.this);
        // check if GPS enabled
        if (gps.canGetLocation()) {
            latitude = gps.getLatitude();
            longitude = gps.getLongitude();
            Geocoder geocoder;
            List<Address> addresses;
            geocoder = new Geocoder(this, Locale.getDefault());
            try {
                addresses = geocoder.getFromLocation(latitude, longitude, 1);
                postalCode = addresses.get(0).getPostalCode();
                city = addresses.get(0).getLocality();
                address = addresses.get(0).getAddressLine(0);
                state = addresses.get(0).getAdminArea();
                country = addresses.get(0).getCountryName();
                knownName = addresses.get(0).getFeatureName();
                Log.e("Location",postalCode+" "+city+" "+address+" "+state+" "+knownName);

            } catch (IOException e) {
                e.printStackTrace();
            }
        } else {
            gps.showSettingsAlert();
        }
    }

Other than "Object.keys( obj )", we have very simple "for...in" loop - which loops over enumerable property names of an object.

const obj = {"fName":"John","lName":"Doe"};_x000D_
_x000D_
for (const key in obj) {_x000D_
    //This will give key_x000D_
      console.log(key);_x000D_
    //This will give value_x000D_
    console.log(obj[key]);_x000D_
    _x000D_
}

Which version of SQL Server?

For SQL Server 2005 and later, you can obtain the SQL script used to create the view like this:

select definition
from sys.objects     o
join sys.sql_modules m on m.object_id = o.object_id
where o.object_id = object_id( 'dbo.MyView')
  and o.type      = 'V'

This returns a single row containing the script used to create/alter the view.

Other columns in the table tell about about options in place at the time the view was compiled.

Caveats

• If the view was last modified with ALTER VIEW, then the script will be an ALTER VIEW statement rather than a CREATE VIEW statement.

• The script reflects the name as it was created. The only time it gets updated is if you execute ALTER VIEW, or drop and recreate the view with CREATE VIEW. If the view has been renamed (e.g., via sp_rename) or ownership has been transferred to a different schema, the script you get back will reflect the original CREATE/ALTER VIEW statement: it will not reflect the objects current name.

• Some tools truncate the output. For example, the MS-SQL command line tool sqlcmd.exe truncates the data at 255 chars. You can pass the parameter -y N to get the result with N chars.

[edit sept 2020]: a snippet containing previous answer and added an arrow function

// a (not very efficient) oneliner
let yesterday = new Date(new Date().setDate(new Date().getDate()-1));
console.log(yesterday);

// a function call
yesterday = ( function(){this.setDate(this.getDate()-1); return this} )
            .call(new Date);
console.log(yesterday);

// an iife (immediately invoked function expression)
yesterday = function(d){ d.setDate(d.getDate()-1); return d}(new Date);
console.log(yesterday);

// oneliner using es6 arrow function
yesterday = ( d => new Date(d.setDate(d.getDate()-1)) )(new Date);
console.log(yesterday);

// use a method
const getYesterday = (dateOnly = false) => {
  let d = new Date();
  d.setDate(d.getDate() - 1);
  return dateOnly ? new Date(d.toDateString()) : d;
};
console.log(getYesterday());
console.log(getYesterday(true));

You are using .net 4? - Maybe on the clients there is only the ".net framework 4 client profile" installed. Try to install full package!! Download here

Make sure you're on the main thread.

If not, it will still save the button text. It will be there when you inspect the object in the debugger. But it won't actually update the view.

There is a cross-platform file locking module here: Portalocker

Although as Kevin says, writing to a file from multiple processes at once is something you want to avoid if at all possible.

If you can shoehorn your problem into a database, you could use SQLite. It supports concurrent access and handles its own locking.

If I understood your question, you want to merge branchB into branchA. To do so, first checkout branchA like below,

git checkout branchA

Then execute the below command to merge branchB into branchA:

git merge branchB

You can use jQuery's .eq() method to get the element with a certain index.

$('ul li').eq(index).css({'background-color':'#343434'});

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)

You had a mistake on the statement below. Use . not ,

echo '<img src="', $dir, '/', $file, '" alt="', $file, $

to

echo '<img src="'. $dir. '/'. $file. '" alt="'. $file. $

and

echo 'Directory \'', $dir, '\' not found!';

to

echo 'Directory \''. $dir. '\' not found!';

With PHP

echo urlencode("http://www.image.com/?username=unknown&password=unknown");

Result

http%3A%2F%2Fwww.image.com%2F%3Fusername%3Dunknown%26password%3Dunknown

With Javascript:

var myUrl = "http://www.image.com/?username=unknown&password=unknown";
var encodedURL= "http://www.foobar.com/foo?imageurl=" + encodeURIComponent(myUrl);

You shouldn't have to set height: 100% at any point if you want your container to fill the page. Chances are, your problem is rooted in the fact that you haven't cleared the floats in the container's children. There are quite a few ways to solve this problem, mainly adding overflow: hidden to the container.

#container { overflow: hidden; }

Should be enough to solve whatever height problem you're having.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

If your web server is IIS, you need to make sure that the new Office 2007 (I see the xlsx suffix) mime types are added to the list of mime types in IIS, otherwise it will refuse to serve the unknown file type.

Here's one link to tell you how:

This will work for MYSQL

SELECT Name FROM Employees WHERE Name REGEXP '^[B].*$'

In this REGEXP stands for regular expression

and

this is for T-SQL

SELECT Name FROM Employees WHERE Name LIKE '[B]%'

You should use LoadXml method, not Load:

xmlDoc.LoadXml(myXML); 

Load method is trying to load xml from a file and LoadXml from a string. You could also use XPath:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);

string xpath = "myDataz/listS/sog";
var nodes = xmlDoc.SelectNodes(xpath);

foreach (XmlNode childrenNode in nodes)
{
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("//field1").Value);
} 

$("html, body").scrollTop($(element).offset().top); // <-- Also integer can be used

This error is very non-descriptive but the key here is that 'ID' is in uppercase. This indicates that the route has not been correctly set up. To let the application handle URLs with an id, you need to make sure that there's at least one route configured for it. You do this in the RouteConfig.cs located in the App_Start folder. The most common is to add the id as an optional parameter to the default route.

public static void RegisterRoutes(RouteCollection routes)
{
    //adding the {id} and setting is as optional so that you do not need to use it for every action
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

Now you should be able to redirect to your controller the way you have set it up.

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index","ProductImageManager", new { id });

    //if the action is in the same controller, you can omit the controller:
    //RedirectToAction("Index", new { id });
}

In one or two occassions way back I ran into some issues by normal redirect and had to resort to doing it by passing a RouteValueDictionary. More information on RedirectToAction with parameter

return RedirectToAction("Index", new RouteValueDictionary( 
    new { controller = "ProductImageManager", action = "Index", id = id } ) 
);

If you get a very similar error but in lowercase 'id', this is usually because the route expects an id parameter that has not been provided (calling a route without the id /ProductImageManager/Index). See this so question for more information.

After INSERT query you can use ROW_COUNT() to check for successful insert operation as:

SELECT IF(ROW_COUNT() = 1,  "Insert Success", "Insert Failed") As status;

<script type="text/javascript">
function AlertFilesize(){
    if(window.ActiveXObject){
        var fso = new ActiveXObject("Scripting.FileSystemObject");
        var filepath = document.getElementById('fileInput').value;
        var thefile = fso.getFile(filepath);
        var sizeinbytes = thefile.size;
    }else{
        var sizeinbytes = document.getElementById('fileInput').files[0].size;
    }

    var fSExt = new Array('Bytes', 'KB', 'MB', 'GB');
    fSize = sizeinbytes; i=0;while(fSize>900){fSize/=1024;i++;}

    alert((Math.round(fSize*100)/100)+' '+fSExt[i]);
}
</script>

<input id="fileInput" type="file" onchange="AlertFilesize();" />

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.

The query with the LIKE keyword showed a clustered index scan.

The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

Another solution using scale_y_log10 with trans_breaks, trans_format and annotation_logticks()

library(ggplot2)

m <- ggplot(diamonds, aes(y = price, x = color))

m + geom_boxplot() +
  scale_y_log10(
    breaks = scales::trans_breaks("log10", function(x) 10^x),
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  ) +
  theme_bw() +
  annotation_logticks(sides = 'lr') +
  theme(panel.grid.minor = element_blank())

You can try below query,

select * from players
where 
    us_reg_date between '2000-07-05'
and
    DATE_ADD('2011-11-10',INTERVAL 1 DAY)

It evaluates to the left operand if the left operand is truthy, and the right operand otherwise.

In pseudocode,

foo = bar ?: baz;

roughly resolves to

foo = bar ? bar : baz;

or

if (bar) {
    foo = bar;
} else {
    foo = baz;
}

with the difference that bar will only be evaluated once.

You can also use this to do a "self-check" of foo as demonstrated in the code example you posted:

foo = foo ?: bar;

This will assign bar to foo if foo is null or falsey, else it will leave foo unchanged.

Some more examples:

<?php
    var_dump(5 ?: 0); // 5
    var_dump(false ?: 0); // 0
    var_dump(null ?: 'foo'); // 'foo'
    var_dump(true ?: 123); // true
    var_dump('rock' ?: 'roll'); // 'rock'
?>

By the way, it's called the Elvis operator.

Basic and simple.

In your adapter simply use this.

((YourParentClass) context).functionToRun();

If you don't have a 3.7 for @dataclass and need mutability, the following code might work for you. It's quite self-documenting and IDE-friendly (auto-complete), prevents writing things twice, is easily extendable and it is very simple to test that all instance variables are completely initialized:

class Params():
    def __init__(self):
        self.var1 : int = None
        self.var2 : str = None

    def are_all_defined(self):
        for key, value in self.__dict__.items():
            assert (value is not None), "instance variable {} is still None".format(key)
        return True


params = Params()
params.var1 = 2
params.var2 = 'hello'
assert(params.are_all_defined)

Weird, your code seems to work for me:

import java.util.Arrays;

public class Test
{
    public static void main(String[] args)
    {
        // args is the list of guests
        Arrays.sort(args);
        for(int i = 0; i < args.length; i++)
            System.out.println(args[i]);
    }
}

I ran that code using "java Test Bobby Joe Angel" and here is the output:

$ java Test Bobby Joe Angel
Angel
Bobby
Joe

If you want to take a copy of a live database, do the Backup/Restore method.

[In SQLS2000, not sure about 2008:] Just keep in mind that if you are using SQL Server accounts in this database, as opposed to Windows accounts, if the master DB is different or out of sync on the development server, the user accounts will not translate when you do the restore. I've heard about an SP to remap them, but I can't remember which one it was.

I would use git restore (available since git 2.23)

git restore --source otherbranch path/to/myfile.txt

Why it is better than other options?

git checkout otherbranch -- path/to/myfile.txt - It copy file to working directory but also to staging area (similar effect as if you would copy this file manually and executed git add on it). git restore doesn't touch staging area (unless told it to by --staged option).

git show otherbranch:path/to/myfile.txt > path/to/myfile.txt uses standard shell redirection. If you use Powershell then there might be problem with text enconding or you could get broken file if it's binary. With git restore changing files is done all by git executable.

Another advantage is that you can restore whole folder with:

git restore --source otherbranch path/to

or with git restore --overlay --source otherbranch path/to if you want to avoid deleting files. For example if there is less files on otherbranch than in current working directory (and these files are tracked) without --overlay option git restore will delete them. But this is good default bahaviour, you most likely want the state of directory to be "the same like in otherbranch", not "the same like in otherbranch but with additional files from my current branch"

It is a unicode char \u003C = <

I just came across this issue, and found custom CSS style sheet text color:#ffffff is submerging the text content, because model background color is same! i.e. .model-content{ background-color:#ffffff;} Make sure to override it in your custom style sheet by adding the following .modal-content{color:#646464 !important;}
May be this helps.

You have to specify Resource for the bucket via "arn:aws:s3:::bucketname" or "arn:aws:3:::bucketname*". The latter is preferred since it allows manipulations on the bucket's objects too. Notice there is no slash!

Listing objects is an operation on Bucket. Therefore, action "s3:ListBucket" is required. Adding an object to the Bucket is an operation on Object. Therefore, action "s3:PutObject" is needed. Certainly, you may want to add other actions as you require.

{
"Version": "version_id",
"Statement": [
    {
        "Sid": "some_id",
        "Effect": "Allow",
        "Action": [
            "s3:ListBucket",
            "s3:PutObject"
        ],
        "Resource": [
            "arn:aws:s3:::bucketname*"
        ]
    }
] 
}

For those looking for less complicated solution. I actually find this one more simplisitic solution that will do similar job:

import pandas as pd
a = ['a','b','c'] 
df = pd.DataFrame({'a': a})
df= df.set_index('a').T
df.to_csv('list_a.csv', index=False)

Hope this helps as well.

i was looking for the same problem and stumbled upon the following code.

How to get Client MAC address(Web):

To get the client MAC address only way we can rely on JavaScript and Active X control of Microsoft.It is only work in IE if Active X enable for IE. As the ActiveXObject is not available with the Firefox, its not working with the firefox and is working fine in IE.

This script is for IE only:

For circle, create a div element and then enter width = 2 times of the border radius = 2 times padding. Also line-height = 0 For example, with 50px as radii of the circle, the below code works well:

width: 100px;
padding: 50px 0;
border: solid;
line-height: 0px;
border-radius: 50px;
