For QT 5.* if you face error at Kits, like No Valid Kits Found, go to Options->Build&Run-> (Kits tab) then you see a Manual category which should list Desktop as the default.

Just go to your OS Terminal and write sudo apt-get install qt5-default, go back to QT Creator and Start your New Project, and there you see the kit option Desktop included in the list.

Here is a theme that I copied all the important parts of the Visual Studio 2013 dark theme.

**Update 08/Sep/15 - Qt Creator 3.5.1/Qt 5.5.1 might have fixed the rest of Qt not being dark properly and hard to read.

I fixed this problem by changing the first line in Application.mk from

APP_STL := gnustl_static

to

APP_STL := c++_static

If you are using qmake, the standard Qt build system, just add a line to the .pro file as documented in the qmake Variable Reference:

INCLUDEPATH += <your path>

If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.

As explained in the Qt Creator Manual, <your path> must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro file by using $$PWD which refers to the folder that contains your .pro file, e.g.

INCLUDEPATH += $$PWD/code/include

Are you using qmake projects? If so, you can add an external library using the LIBS variable. E.g:

win32:LIBS += path/to/Psapi.lib

Based on some (minimal) benchmarks using the timeit module it seems that the following has similar if not better performance than the accepted answer

new_lst = [a, *lst]

As with [a] + list this will create a new list and not mutate lst.

If your intention is to mutate the list then use lst.insert(0, a).

In my case, it was WordPress that now requires PHP 7.4 and I was running 7.2.
As soon as I updated, the errors disappeared.

With latest version of windows (e.g. Windows 10, other servers), type/search for "Developers Command prompt.." It will pop up the relevant command prompt for the Visual Studio version.

e.g. Developer Command Prompt for VS 2015

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;

Very few people realize the power of css positioning. To set the map to occupy 100% height of it's parent container do following:

#map_canvas_container {position: relative;}

#map_canvas {position: absolute; top: 0; right: 0; bottom: 0; left: 0;}

If you have any non absolutely positioned elements inside #map_canvas_container they will set the height of it and the map will take the exact available space.

For zooming your map two level then just add this small code of line map.setZoom(map.getZoom() + 2);

I don't like setting CLASSPATH. CLASSPATH is a global variable and as such it is evil:

• If you modify it in one script, suddenly some java programs will stop working.
• If you put there the libraries for all the things which you run, and it gets cluttered.
• You get conflicts if two different applications use different versions of the same library.
• There is no performance gain as libraries in the CLASSPATH are not shared - just their name is shared.
• If you put the dot (.) or any other relative path in the CLASSPATH that means a different thing in each place - that will cause confusion, for sure.

Therefore the preferred way is to set the classpath per each run of the jvm, for example:

java -Xmx500m -cp ".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar"    "folder.subfolder../dit1/some.xml

If it gets long the standard procedure is to wrap it in a bash or batch script to save typing.

The syntax you are using is new to SQL Server 2008:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test'),(1001,N'test2')

For SQL Server 2005, you will have to use multiple INSERT statements:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test')

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1001,N'test2')

One other option is to use UNION ALL:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
SELECT 1000, N'test' UNION ALL
SELECT 1001, N'test2'

Try this

textarea::-webkit-input-placeholder {  color: #999;}

Nothing built-in that I know of.

Apache Commons Lang has a class called StringUtils which contains many join functions.

big=small=values[0]; //assigns element to be highest or lowest value

Should be AFTER fill loop

//counts to 20 and prompts user for value and stores it
for ( int i = 0; i < 20; i++ )
{
    cout << "Enter value " << i << ": ";
    cin >> values[i];
}
big=small=values[0]; //assigns element to be highest or lowest value

since when you declare array - it's unintialized (store some undefined values) and so, your big and small after assigning would store undefined values too.

And of course, you can use std::min_element, std::max_element, or std::minmax_element from C++11, instead of writing your loops.

I would suggest using conda. Conda is an anconda specific package manager. If you want to know more about conda, read the conda docs.

Using conda in the command line, the command below would install scipy 0.17.

conda install scipy=0.17.0

The problem with other answers is they either use a global, which can be overwritten when several functions are in a call chain, or echo which means your function cannot output diagnostic info (you will forget your function does this and the "result", i.e. return value, will contain more info than your caller expects, leading to weird bug), or eval which is way too heavy and hacky.

The proper way to do this is to put the top level stuff in a function and use a local with bash's dynamic scoping rule. Example:

func1() 
{
    ret_val=hi
}

func2()
{
    ret_val=bye
}

func3()
{
    local ret_val=nothing
    echo $ret_val
    func1
    echo $ret_val
    func2
    echo $ret_val
}

func3

This outputs

nothing
hi
bye

Dynamic scoping means that ret_val points to a different object depending on the caller! This is different from lexical scoping, which is what most programming languages use. This is actually a documented feature, just easy to miss, and not very well explained, here is the documentation for it (emphasis is mine):

Variables local to the function may be declared with the local builtin. These variables are visible only to the function and the commands it invokes.

For someone with a C/C++/Python/Java/C#/javascript background, this is probably the biggest hurdle: functions in bash are not functions, they are commands, and behave as such: they can output to stdout/stderr, they can pipe in/out, they can return an exit code. Basically there is no difference between defining a command in a script and creating an executable that can be called from the command line.

So instead of writing your script like this:

top-level code 
bunch of functions
more top-level code

write it like this:

# define your main, containing all top-level code
main() 
bunch of functions
# call main
main  

where main() declares ret_val as local and all other functions return values via ret_val.

See also the following Unix & Linux question: Scope of Local Variables in Shell Functions.

Another, perhaps even better solution depending on situation, is the one posted by ya.teck which uses local -n.

Yes with Virtual Host you can have as many parallel programs as you want:

If path is not hardcoded in any script then your websites should work seamlessly.

Key Point: Add both http://localhost and http://localhost:port_number to the Authorized JavaScript origins box for local tests or development.

In addition, you can continue to include a persistent link in the settings or configuration screens of your app that deep-links to your App Store product page. To automatically open a page on which users can write a review in the App Store, append the query parameter action=write-review to your product URL.

So the URL would be the following:

itms-apps://itunes.apple.com/app/idYOUR_APP_ID?action=write-review

You can use cv2.rectangle():

cv2.rectangle(img, pt1, pt2, color, thickness, lineType, shift)

Draws a simple, thick, or filled up-right rectangle.

The function rectangle draws a rectangle outline or a filled rectangle
whose two opposite corners are pt1 and pt2.

Parameters
    img   Image.
    pt1   Vertex of the rectangle.
    pt2    Vertex of the rectangle opposite to pt1 .
    color Rectangle color or brightness (grayscale image).
    thickness  Thickness of lines that make up the rectangle. Negative values,
    like CV_FILLED , mean that the function has to draw a filled rectangle.
    lineType  Type of the line. See the line description.
    shift   Number of fractional bits in the point coordinates.

I have a PIL Image object and I want to draw rectangle on this image, but PIL's ImageDraw.rectangle() method does not have the ability to specify line width. I need to convert Image object to opencv2's image format and draw rectangle and convert back to Image object. Here is how I do it:

# im is a PIL Image object
im_arr = np.asarray(im)
# convert rgb array to opencv's bgr format
im_arr_bgr = cv2.cvtColor(im_arr, cv2.COLOR_RGB2BGR)
# pts1 and pts2 are the upper left and bottom right coordinates of the rectangle
cv2.rectangle(im_arr_bgr, pts1, pts2,
              color=(0, 255, 0), thickness=3)
im_arr = cv2.cvtColor(im_arr_bgr, cv2.COLOR_BGR2RGB)
# convert back to Image object
im = Image.fromarray(im_arr)

If you have PHP & PHP-memcached installed, you can run

$ php -r '$c = new Memcached(); $c->addServer("localhost", 11211); var_dump( $c->getAllKeys() );'

For anybody reading this in 2019, after React 16.8 was released, take a look at the React Hooks. It really simplifies handling states in components. The docs are very well written with an example of exactly what you need.

You can divide column of dtype timedelta by np.timedelta64(1, 'D'), but output is not int, but float, because NaN values:

Changing Tomcat config wont effect all JVM instances to get theses settings. This is not how it works, the setting will be used only to launch JVMs used by Tomcat, not started in the shell.

Look here for permanently changing the heap size.

Based on the answer of @erwanp, you can use the formatted string literals of Python 3,

x = '2'
percentage = f'{x}%' # 2%

inside the FuncFormatter() and combined with a lambda expression.

All wrapped:

ax.yaxis.set_major_formatter(FuncFormatter(lambda y, _: f'{y}%'))

HTML Code:

<div id="welcomeDiv"  style="display:none;" class="answer_list" > WELCOME</div>
<input type="button" name="answer" value="Show Div" onclick="showDiv()" />

Javascript:

function showDiv() {
   document.getElementById('welcomeDiv').style.display = "block";
}

See the Demo: http://jsfiddle.net/rathoreahsan/vzmnJ/

The tick_params method is very useful for stuff like this. This code turns off major and minor ticks and removes the labels from the x-axis.

from matplotlib import pyplot as plt
plt.plot(range(10))
plt.tick_params(
    axis='x',          # changes apply to the x-axis
    which='both',      # both major and minor ticks are affected
    bottom=False,      # ticks along the bottom edge are off
    top=False,         # ticks along the top edge are off
    labelbottom=False) # labels along the bottom edge are off
plt.show()
plt.savefig('plot')
plt.clf()

I had been facing this problem for two days and I found that the directory you create in Oracle also needs to created first on your physical disk.

I didn't find this point mentioned anywhere i tried to look up the solution to this.

Example

If you created a directory, let's say, 'DB_DIR'.

CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DB_WORKS';

Then you need to ensure that DB_WORKS exists in your E:\ drive and also file system level Read/Write permissions are available to the Oracle process.

My understanding of UTL_FILE from my experiences is given below for this kind of operation.

UTL_FILE is an object under SYS user. GRANT EXECUTE ON SYS.UTL_FILE TO PUBLIC; needs to given while logged in as SYS. Otherwise, it will give declaration error in procedure. Anyone can create a directory as shown:- CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DBWORKS'; But CREATE DIRECTORY permission should be in place. This can be granted as shown:- GRANT CREATE ALL DIRECTORY TO user; while logged in as SYS user. However, if this needs to be used by another user, grants need to be given to that user otherwise it will throw error. GRANT READ, WRITE, EXECUTE ON DB_DIR TO user; while loggedin as the user who created the directory. Then, compile your package. Before executing the procedure, ensure that the Directory exists physically on your Disk. Otherwise it will throw 'Invalid File Operation' error. (V. IMPORTANT) Ensure that Filesystem level Read/Write permissions are in place for the Oracle process. This is separate from the DB level permissions granted.(V. IMPORTANT) Execute procedure. File should get populated with the result set of your query.

This may not specifically answer your long 3 part question but this thread is old and I found this while searching today. Here is one shorter way to: "Wait until a process has finished." If you know the name of the process such as "EXCEL.EXE"

strProcess = "EXCEL.EXE"    
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Set colProcesses = objWMIService.ExecQuery ("Select * from Win32_Process Where Name = '"& strProcess &"'")
Do While colProcesses.Count > 0
    Set colProcesses = objWMIService.ExecQuery ("Select * from Win32_Process Where Name = '"& strProcess &"'")
    Wscript.Sleep(1000) 'Sleep 1 second
   'msgbox colProcesses.count 'optional to show the loop works
Loop

It's hard to say without seeing the rest of your CSS, but try adding !important in front of the border color, to make it like so:

#refundReasonMenu #nav li:last-child
{
  border-bottom: 1px solid #b5b5b5 !important;
}

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:

    HttpPost req = new HttpPost(composeTargetUrl());
    MultipartEntity entity = new MultipartEntity();
    entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
    try {
        entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException(e);
    }
    req.setEntity(entity);

You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

Following are the most commonly used calls for downloading files in python:

1. urllib.urlretrieve ('url_to_file', file_name)

2. urllib2.urlopen('url_to_file')

3. requests.get(url)

4. wget.download('url', file_name)

Note: urlopen and urlretrieve are found to perform relatively bad with downloading large files (size > 500 MB). requests.get stores the file in-memory until download is complete.

To get all the counts for all the columns in a dataframe, it's just df.count()

Remove semicolon and you can see that link: http://www.ntu.edu.sg/home/ehchua/programming/howto/Tomcat_HowTo.html

To reduce memory consumption and to speed up the search you may use -ReadCount option of Get-Content cmdlet (https://technet.microsoft.com/ru-ru/library/hh849787.aspx).

This may save hours when you working with large files.

Here is an example:

$n = 60699010
$src = 'hugefile.csv'
$batch = 100
$timer = [Diagnostics.Stopwatch]::StartNew()

$count = 0
Get-Content $src -ReadCount $batch -TotalCount $n | %  { 
    $count += $_.Length
    if ($count -ge $n ) {
        $_[($n - $count + $_.Length - 1)]
    }
}

$timer.Stop()
$timer.Elapsed

This prints $n'th line and elapsed time.

You can decide whether or not to implement such features; there is no dedicated API for any of the features just listed, so providing them is a competitive advantage.

Apple document is saying there is no API available for this feature and some other expected feature in a customkeyboard. so you need to find out your own logic to implement this.

In many cases, this may be an XY Problem. Why are you indexing your dictionary keys by position? Do you really need to? Until recently, dictionaries were not even ordered in Python, so accessing the first element was arbitrary.

I just translated some Python 2 code to Python 3:

keys = d.keys()
for (i, res) in enumerate(some_list):
    k = keys[i]
    # ...

which is not pretty, but not very bad either. At first, I was about to replace it by the monstrous

    k = next(itertools.islice(iter(keys), i, None))

before I realised this is all much better written as

for (k, res) in zip(d.keys(), some_list):

which works just fine.

I believe that in many other cases, indexing dictionary keys by position can be avoided. Although dictionaries are ordered in Python 3.7, relying on that is not pretty. The code above only works because the contents of some_list had been recently produced from the contents of d.

Have a hard look at your code if you really need to access a disk_keys element by index. Perhaps you don't need to.

Yes, you can assign one instance of a struct to another using a simple assignment statement.

• In the case of non-pointer or non pointer containing struct members, assignment means copy.

• In the case of pointer struct members, assignment means pointer will point to the same address of the other pointer.

Let us see this first hand:

#include <stdio.h>

struct Test{
    int foo;
    char *bar;
};

int main(){
    struct Test t1;
    struct Test t2;
    t1.foo = 1;
    t1.bar = malloc(100 * sizeof(char));
    strcpy(t1.bar, "t1 bar value");
    t2.foo = 2;
    t2.bar = malloc(100 * sizeof(char));
    strcpy(t2.bar, "t2 bar value");
    printf("t2 foo and bar before copy: %d %s\n", t2.foo, t2.bar);
    t2 = t1;// <---- ASSIGNMENT
    printf("t2 foo and bar after copy: %d %s\n", t2.foo, t2.bar);
    //The following 3 lines of code demonstrate that foo is deep copied and bar is shallow copied
    strcpy(t1.bar, "t1 bar value changed");
    t1.foo = 3;
    printf("t2 foo and bar after t1 is altered: %d %s\n", t2.foo, t2.bar);
    return 0;
}

This expression 12-4-2005 is a calculated int and the value is -1997. You should do like this instead '2005-04-12' with the ' before and after.

Sometimes due to out of memory space error, NetBeans does not load or find main class.

If you have tried setting the properties and still it is not working then try

Any model which don't identify resource and the action associated with is restless. restless is not any term but a slang term to represent all other services that doesn't abide with the above definition. In restful model resource is identified by URL (NOUN) and the actions(VERBS) by the predefined methods in HTTP protocols i.e. GET, POST, PUT, DELETE etc.

Instructions

First, insert these lines wherever you want within your newsletter code. Then:

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.

Make sure that the htaccess file is readable by apache:

chmod 644 /var/www/abc/.htaccess 

And make sure the directory it's in is readable and executable:

chmod 755 /var/www/abc/

You can use margin auto. With flex, the div seems to be centered vertically too.

body,
html {
  height: 100%;
  margin: 0;
}
.site {
  height: 100%;
  display: flex;
}
.site .box {
  background: #0ff;
  max-width: 20vw;
  margin: auto;
}

<div class="site">
  <div class="box">
    <h1>blabla</h1>
    <p>blabla</p>

Pull multiple files using regex:

Create pullFiles.sh:

#!/bin/bash
HOST_DIR=<pull-to>
DEVICE_DIR=/sdcard/<pull-from>
EXTENSION=".jpg"

for file in $(adb shell ls $DEVICE_DIR | grep $EXTENSION'$')
do
    file=$(echo -e $file | tr -d "\r\n"); # EOL fix
    adb pull $DEVICE_DIR/$file $HOST_DIR/$file;
done

Run it:

Make it executable: chmod +x pullFiles.sh

Run it: ./pullFiles.sh

Notes:

• as is, won't work when filenames have spaces
• includes a fix for end-of-line (EOL) on Android, which is a "\r\n"

The endpoint of the term is the URL that is focused on creating a request. Take a look at the following examples from different points:

/api/groups/6/workings/1
/api/v2/groups/5/workings/2
/api/workings/3

They can clearly access the same source in a given API.

In order to use Qt with dynamic linking you have to specify the lib files (usually qtmaind.lib, QtCored4.lib and QtGuid4.lib for the "Debug" configration) in
Properties » Linker » Input » Additional Dependencies.

You also have to specify the path where the libs are, namely in
Properties » Linker » General » Additional Library Directories.

And you need to make the corresponding .dlls are accessible at runtime, by either storing them in the same folder as your .exe or in a folder that is on your path.

If you use a full screen table you are maybe interested in setting th to display:fixed; and top:0; or try a very similar approach via css.

Ok in this example you are getting duplicates because you are joining both D and S onto M. I assume you should be joining D.id onto S.id like below:

SELECT *
FROM M
INNER JOIN S
    on M.Id = S.Id
INNER JOIN D
    ON S.Id = D.Id
INNER JOIN H
    ON D.Id = H.Id

From Save (Not Permitted) Dialog Box on MSDN :

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column <<<<

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

Saving changes is not permitted in SQL 2008 Management Studio

Probably the new PyCharm from the makers of IntelliJ and ReSharper.

You are iterating trough items in words but you have to iterate through item's length:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in range(len(words)):
    w1 = words[i]
    if w1[0] == w1[len(w1) - 1]:
      c += 1
    print (c)

In your case i[0] is 'aba' because i is calculated from items in words:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in words:
print(i)

the output is:

aba

Python 3: new exec (execfile dropped) !

The execfile solution is valid only for Python 2. Python 3 dropped the execfile function - and promoted the exec statement to a builtin universal function. As the comment in Python 3.0's changelog and Hi-Angels comment suggest:

use

exec(open(<filename.py>).read())

instead of

execfile(<filename.py>)

Here is a CSS solution that works beautifully. The content is added (and absolutely positioned relative to the container) after the containing element (via :after pseudo-class).

It gets its text from the placeholder attribute that I defined where I used the directive (attr(placeholder)). Another key factor is pointer-events: none - this allows clicks on the placeholder text to pass through to the select. Otherwise it won't drop down if the user clicks the text.

I add the .empty class myself in my select directive, but normally I find that angular adds/removes .ng-empty for me (I assume it's because I'm injecting version 1.2 of Angular in my code sample).

(The sample also demonstrates how to wrap HTML elements in AngularJS to create your own custom inputs)

Try to check Signing settings in Build settings for your project and target. Be sure that code signing identity section has correct identities for Debug and Release.

You need to pass the labels to be dropped.

df.drop(df.index, inplace=True)

By default, it operates on axis=0.

You can achieve the same with

df.iloc[0:0]

which is much more efficient.

if(isset($rule["type"]) && ($rule["type"] == "radio") || ($rule["type"] == "checkbox") )
{
    if(!isset($data[$field]))
        $data[$field]="";
}

One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list

You dont need jquery-migrate. Summarizing previous answers, here is a working html:

<html>
<body>
  <a id='linkButton'>ClickMe</a>
  <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
  <link href="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/css/toastr.css" rel="stylesheet"/>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/js/toastr.js"></script>
  <script type="text/javascript">
  $(document).ready(function() {
    toastr.options.timeOut = 1500; // 1.5s
    toastr.info('Page Loaded!');
    $('#linkButton').click(function() {
       toastr.success('Click Button');
    });
  });
  </script>

I would suggest using String.format() if you need the value as a String in your code.

For example, you can use String.format() in the following way:

float myFloat = 2.001f;

String formattedString = String.format("%.02f", myFloat);

I had a similar problem and stumbled upon this question, and know thanks to Nick Olson-Harris' answer that the solution lies with changing the string.

Two ways of solving it:

1. Get the path you want using native python functions, e.g.:

   test = os.getcwd() # In case the path in question is your current directory
   print(repr(test))
   

   This makes it platform independent and it now works with .encode. If this is an option for you, it's the more elegant solution.

2. If your string is not a path, define it in a way compatible with python strings, in this case by escaping your backslashes:

   test = 'C:\\Windows\\Users\\alexb\\'
   print(repr(test))
   

aca definis los anchos

 float[] anchoDeColumnas= new float[] {10f, 20f, 30f, 10f};

aca se los insertas a la tabla que tiene las columnas

table.setWidths(anchoDeColumnas);

If you have your text in your_text variable, you can use:

your_text[0..29]

It should wait until get request completed. After that I'll return get request body from where function is called.

function foo() {
    var jqXHR = $.ajax({
        url: url,
        type: 'GET',
        async: false,
    });
    return JSON.parse(jqXHR.responseText);  
}

Use which(mydata_2$height_chad1 == 2585)

Short example

df <- data.frame(x = c(1,1,2,3,4,5,6,3),
                 y = c(5,4,6,7,8,3,2,4))
df
  x y
1 1 5
2 1 4
3 2 6
4 3 7
5 4 8
6 5 3
7 6 2
8 3 4

which(df$x == 3)
[1] 4 8

length(which(df$x == 3))
[1] 2

count(df, vars = "x")
  x freq
1 1    2
2 2    1
3 3    2
4 4    1
5 5    1
6 6    1

df[which(df$x == 3),]
  x y
4 3 7
8 3 4

As Matt Weller pointed out, you can use the length function. The count function in plyr can be used to return the count of each unique column value.

Expanding on @gecco 's answer, the following is an example that'll show you the difference:

def foo(**kwargs):
    for entry in kwargs.items():
        print("Key: {}, value: {}".format(entry[0], entry[1]))

# call using normal keys:
foo(a=1, b=2, c=3)
# call using an unpacked dictionary:
foo(**{"a": 1, "b":2, "c":3})

# call using a dictionary fails because the function will think you are
# giving it a positional argument
foo({"a": 1, "b": 2, "c": 3})
# this yields the same error as any other positional argument
foo(3)
foo("string")

Here you can see how unpacking a dictionary works, and why sending an actual dictionary fails

If you're using Unity, you don't need to change this in Xcode, you can apply a compile flag in the metadata for the specific file(s), right inside Unity. Just select them in the Project panel, and apply from the Inspector panel. This is essential if you plan on using Cloud Build.

You can just specify the python version when running a program:

for python 2:

python filename.py

for python 3:

python3 filename.py

always works well:

function getCookie(cname) {
    var name = cname + "=",
        ca = document.cookie.split(';'),
        i,
        c,
        ca_length = ca.length;
    for (i = 0; i < ca_length; i += 1) {
        c = ca[i];
        while (c.charAt(0) === ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) !== -1) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

function setCookie(variable, value, expires_seconds) {
    var d = new Date();
    d = new Date(d.getTime() + 1000 * expires_seconds);
    document.cookie = variable + '=' + value + '; expires=' + d.toGMTString() + ';';
}

No requirements for jQuery or anything. Pure old good JavaScript.

Not knowing exactly what you want to do... but still here's a possible solution.

Create a scope with a '&'-property in the local scope. It "provides a way to execute an expression in the context of the parent scope" (see the directive documentation for details).

I also noticed that you used a shorthand linking function and shoved in object attributes in there. You can't do that. It is more clear (imho) to just return the directive-definition object. See my code below.

Here's a code sample and a fiddle.

<div ng-app="myApp">
<div ng-controller="myController">
    <div my-method='theMethodToBeCalled'>Click me</div>
</div>
</div>

<script>

   var app = angular.module('myApp',[]);

   app.directive("myMethod",function($parse) {
       var directiveDefinitionObject = {
         restrict: 'A',
         scope: { method:'&myMethod' },
         link: function(scope,element,attrs) {
            var expressionHandler = scope.method();
            var id = "123";

            $(element).click(function( e, rowid ) {
               expressionHandler(id);
            });
         }
       };
       return directiveDefinitionObject;
   });

   app.controller("myController",function($scope) {
      $scope.theMethodToBeCalled = function(id) { 
          alert(id); 
      };
   });

</script>

Delimiters other than the default ; are typically used when defining functions, stored procedures, and triggers wherein you must define multiple statements. You define a different delimiter like $$ which is used to define the end of the entire procedure, but inside it, individual statements are each terminated by ;. That way, when the code is run in the mysql client, the client can tell where the entire procedure ends and execute it as a unit rather than executing the individual statements inside.

Note that the DELIMITER keyword is a function of the command line mysql client (and some other clients) only and not a regular MySQL language feature. It won't work if you tried to pass it through a programming language API to MySQL. Some other clients like PHPMyAdmin have other methods to specify a non-default delimiter.

Example:

DELIMITER $$
/* This is a complete statement, not part of the procedure, so use the custom delimiter $$ */
DROP PROCEDURE my_procedure$$

/* Now start the procedure code */
CREATE PROCEDURE my_procedure ()
BEGIN    
  /* Inside the procedure, individual statements terminate with ; */
  CREATE TABLE tablea (
     col1 INT,
     col2 INT
  );

  INSERT INTO tablea
    SELECT * FROM table1;

  CREATE TABLE tableb (
     col1 INT,
     col2 INT
  );
  INSERT INTO tableb
    SELECT * FROM table2;
  
/* whole procedure ends with the custom delimiter */
END$$

/* Finally, reset the delimiter to the default ; */
DELIMITER ;

Attempting to use DELIMITER with a client that doesn't support it will cause it to be sent to the server, which will report a syntax error. For example, using PHP and MySQLi:

$mysqli = new mysqli('localhost', 'user', 'pass', 'test');
$result = $mysqli->query('DELIMITER $$');
echo $mysqli->error;

Errors with:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER $$' at line 1

Got the most easiest hack for this problem-use this syntax in your HTML-input-tag

      <input type="text" id="my_element_id" placeholder="select a date" name="my_element_name" onfocus="(this.type='date')" />
      </div>

word-wrap: break-word; 

add this to your container that should do the trick

var_export provides the desired functionality.

This will always print a value rather than printing nothing for null or false. var_export prints a PHP representation of the argument it's passed, the output could be copy/pasted back into PHP.

var_export(true);    // true
var_export(false);   // false
var_export(1);       // 1
var_export(0);       // 0
var_export(null);    // NULL
var_export('true');  // 'true'   <-- note the quotes
var_export('false'); // 'false'

If you want to print strings "true" or "false", you can cast to a boolean as below, but beware of the peculiarities:

var_export((bool) true);   // true
var_export((bool) false);  // false
var_export((bool) 1);      // true
var_export((bool) 0);      // false
var_export((bool) '');     // false
var_export((bool) 'true'); // true
var_export((bool) null);   // false

// !! CAREFUL WITH CASTING !!
var_export((bool) 'false'); // true
var_export((bool) '0');     // false

Note: The original question was answered already, but I would just like to expand on it with some extras that are relevant to the topic.

Your AIX installation would first be put into volume groups. This is done upon installation.

It will first create rootvg (as in root volume group). This is kinda like your actual hard drive mapped.

This would be equivalent to Disc Management in Windows. AIX wont use up all of that space for its file systems like we tend to do it in consumer Windows machines. Instead there will be a good bit of unallocated space.

To check how much space your rootvg would have you use the following command.

lsvg rootvg

That would stand for list volume group rootvg. This will give you information like the size of physical partitions (PP), Total PPs assigned to the volume group, Free PPs in the volume group, etc. Regardless, the output should be fairly comprehensive.

Next thing you may be interested in, is the file systems on the volume group. Each file system would have certain amount of space given within the volume group it belongs to.

To check what file systems you got on your volume group you use the following command.

lsvgfs rootvg

As in list volume group file systems for rootvg.

You can check how much space each file system has using the following command.

df

I personally like to refine it with flags like -m and -g (in megabytes and gigabytes respectively)

If you have free space available in your volume group, you can assign it to your file systems using the following command.

chfs -a size=+1G /home

As in change file system attribute size by adding 1 G where file system is /home. use man chfs for more instructions. This is a powerful tool. This example is for adjusting size, however you can do more with this command than that.

Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here

However, the text is very confusion and contradicts itself.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.

But underneath it states that these are the supported platforms.

Supported Platforms:

• .NET Framework 4

• Windows 8

• Windows Phone 8.1

• Windows Phone Silverlight 7.5

• Silverlight 4

• Portable Class Libraries

Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.

I solved it writing a simple function to copy multidimensional int arrays using System.arraycopy

public static void arrayCopy(int[][] aSource, int[][] aDestination) {
    for (int i = 0; i < aSource.length; i++) {
        System.arraycopy(aSource[i], 0, aDestination[i], 0, aSource[i].length);
    }
}

or actually I improved it for for my use case:

/**
 * Clones the provided array
 * 
 * @param src
 * @return a new clone of the provided array
 */
public static int[][] cloneArray(int[][] src) {
    int length = src.length;
    int[][] target = new int[length][src[0].length];
    for (int i = 0; i < length; i++) {
        System.arraycopy(src[i], 0, target[i], 0, src[i].length);
    }
    return target;
}

If you are on Mac OS Big Sur, then you probably have a messed up java installation. I found info on how to fix the issue with this article: https://knasmueller.net/how-to-install-java-openjdk-15-on-macos-big-sur

1. Download the .tar.gz file of the JDK on https://jdk.java.net/15/
2. Navigate to the download folder, and run these commands (move the .tar.gz file, extract it and remove it after extraction):

sudo mv openjdk-15.0.2_osx-x64_bin.tar.gz /Library/Java/JavaVirtualMachines/
cd /Library/Java/JavaVirtualMachines/
sudo tar -xzf openjdk-15.0.2_osx-x64_bin.tar.gz
sudo rm openjdk-15.0.2_osx-x64_bin.tar.gz

Note: it might be 15.0.3 or higher, depending on the date of your download.

3. run /usr/libexec/java_home -v15 and copy the output
4. add this line to your .bash_profile or .zshrc file, depending on which shell you are using. You will probably have only one of these files existing in your home directory (~/.bash_profile or ~/.zshrc).

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.0.2.jdk/Contents/Home

5. save the changes and make them effective right away by running: source ~/.bash_profile or source ~/.zshrc
6. check that java is working - run java -v

If you are using Anaconda with python 3.5, this is a problem in the Anaconda release. (Refer this issue)

You can fix this issue by copying python3.dll file to Anaconda3 folder (where python.exe is located)

How to get "python3.dll"

• In cmd, type python --version to find whether your installation is 64-bit or 32-bit
• download python 3.x embeddable zip file from here
• Extract the zip file and copy python3.dll file to Anaconda3 folder

But if you can move to Anaconda with python 3.6 you will not face this issue. If it is possible for you, then it is the recommended way..

For ENTER key, why not use (keyup.enter):

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="values=box.value">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  values = '';
}

The assertNotNull() method means "a passed parameter must not be null": if it is null then the test case fails.
The assertNull() method means "a passed parameter must be null": if it is not null then the test case fails.

String str1 = null;
String str2 = "hello";              

// Success.
assertNotNull(str2);

// Fail.
assertNotNull(str1);

// Success.
assertNull(str1);

// Fail.
assertNull(str2);

The XML document:

<Home>
    <Addr>
        <Street>ABC</Street>
        <Number>5</Number>
        <Comment>BLAH BLAH BLAH <br/><br/>ABC</Comment>
    </Addr>
</Home>

The XPath expression:

//*[contains(text(), 'ABC')]

//* matches any descendant element of the root node. That is, any element but the root node.

[...] is a predicate, it filters the node-set. It returns nodes for which ... is true:

A predicate filters a node-set [...] to produce a new node-set. For each node in the node-set to be filtered, the PredicateExpr is evaluated [...]; if PredicateExpr evaluates to true for that node, the node is included in the new node-set; otherwise, it is not included.

contains('haystack', 'needle') returns true if haystack contains needle:

Function: boolean contains(string, string)

The contains function returns true if the first argument string contains the second argument string, and otherwise returns false.

But contains() takes a string as its first parameter. And it's passed nodes. To deal with that every node or node-set passed as the first parameter is converted to a string by the string() function:

An argument is converted to type string as if by calling the string function.

string() function returns string-value of the first node:

A node-set is converted to a string by returning the string-value of the node in the node-set that is first in document order. If the node-set is empty, an empty string is returned.

string-value of an element node:

The string-value of an element node is the concatenation of the string-values of all text node descendants of the element node in document order.

string-value of a text node:

The string-value of a text node is the character data.

So, basically string-value is all text that is contained in a node (concatenation of all descendant text nodes).

text() is a node test that matches any text node:

The node test text() is true for any text node. For example, child::text() will select the text node children of the context node.

Having that said, //*[contains(text(), 'ABC')] matches any element (but the root node), the first text node of which contains ABC. Since text() returns a node-set that contains all child text nodes of the context node (relative to which an expression is evaluated). But contains() takes only the first one. So for the document above the path matches the Street element.

The following expression //*[text()[contains(., 'ABC')]] matches any element (but the root node), that has at least one child text node, that contains ABC. . represents the context node. In this case, it's a child text node of any element but the root node. So for the document above the path matches the Street, and the Comment elements.

Now then, //*[contains(., 'ABC')] matches any element (but the root node) that contains ABC (in the concatenation of the descendant text nodes). For the document above it matches the Home, the Addr, the Street, and the Comment elements. As such, //*[contains(., 'BLAH ABC')] matches the Home, the Addr, and the Comment elements.

Also you can try this:

[style.background-image]="'url(' + photo + ')'"

To complete other answers, the gem-path gem can find the installation path of a particular gem.

Installation:

gem install gem-path

Usage:

gem path rails
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-4.0.13
gem path rails '< 4'
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-3.2.21

This is really handy as you can use it to grep or edit files:

grep -R 'Internal server error' "$(gem path thin)"
subl "$(gem path thin)"

Once you've done this

group p by p.SomeId into pg  

you no longer have access to the range variables used in the initial from. That is, you can no longer talk about p or bp, you can only talk about pg.

Now, pg is a group and so contains more than one product. All the products in a given pg group have the same SomeId (since that's what you grouped by), but I don't know if that means they all have the same BaseProductId.

To get a base product name, you have to pick a particular product in the pg group (As you are doing with SomeId and CountryCode), and then join to BaseProducts.

var result = from p in Products                         
 group p by p.SomeId into pg                         
 // join *after* group
 join bp in BaseProducts on pg.FirstOrDefault().BaseProductId equals bp.Id         
 select new ProductPriceMinMax { 
       SomeId = pg.FirstOrDefault().SomeId, 
       CountryCode = pg.FirstOrDefault().CountryCode, 
       MinPrice = pg.Min(m => m.Price), 
       MaxPrice = pg.Max(m => m.Price),
       BaseProductName = bp.Name  // now there is a 'bp' in scope
 };

That said, this looks pretty unusual and I think you should step back and consider what you are actually trying to retrieve.

mongoexport  --help
....
-f [ --fields ] arg     comma separated list of field names e.g. -f name,age
--fieldFile arg         file with fields names - 1 per line

You have to manually specify it and if you think about it, it makes perfect sense. MongoDB is schemaless; CSV, on the other hand, has a fixed layout for columns. Without knowing what fields are used in different documents it's impossible to output the CSV dump.

If you have a fixed schema perhaps you could retrieve one document, harvest the field names from it with a script and pass it to mongoexport.

You can do this:

satView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

       @Override
       public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

       }
   }
);     

Unfortunately it seems that the two most commonly suggested solutions to this issue, namely counting callback occurrences and posting a Runnable to set the callback at a later time can both fail when for example accessibility options are enabled. Here's a helper class that works around these issues. Further explenation is in the comment block.

import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.Spinner;
import android.widget.SpinnerAdapter;

/**
 * Spinner Helper class that works around some common issues 
 * with the stock Android Spinner
 * 
 * A Spinner will normally call it's OnItemSelectedListener
 * when you use setSelection(...) in your initialization code. 
 * This is usually unwanted behavior, and a common work-around 
 * is to use spinner.post(...) with a Runnable to assign the 
 * OnItemSelectedListener after layout.
 * 
 * If you do not call setSelection(...) manually, the callback
 * may be called with the first item in the adapter you have 
 * set. The common work-around for that is to count callbacks.
 * 
 * While these workarounds usually *seem* to work, the callback
 * may still be called repeatedly for other reasons while the 
 * selection hasn't actually changed. This will happen for 
 * example, if the user has accessibility options enabled - 
 * which is more common than you might think as several apps 
 * use this for different purposes, like detecting which 
 * notifications are active.
 * 
 * Ideally, your OnItemSelectedListener callback should be
 * coded defensively so that no problem would occur even
 * if the callback was called repeatedly with the same values
 * without any user interaction, so no workarounds are needed.
 * 
 * This class does that for you. It keeps track of the values
 * you have set with the setSelection(...) methods, and 
 * proxies the OnItemSelectedListener callback so your callback
 * only gets called if the selected item's position differs 
 * from the one you have set by code, or the first item if you
 * did not set it.
 * 
 * This also means that if the user actually clicks the item
 * that was previously selected by code (or the first item
 * if you didn't set a selection by code), the callback will 
 * not fire.
 * 
 * To implement, replace current occurrences of:
 * 
 *     Spinner spinner = 
 *         (Spinner)findViewById(R.id.xxx);
 *     
 * with:
 * 
 *     SpinnerHelper spinner = 
 *         new SpinnerHelper(findViewById(R.id.xxx))
 *         
 * SpinnerHelper proxies the (my) most used calls to Spinner
 * but not all of them. Should a method not be available, use: 
 * 
 *      spinner.getSpinner().someMethod(...)
 *
 * Or just add the proxy method yourself :)
 * 
 * (Quickly) Tested on devices from 2.3.6 through 4.2.2

There's a few ways, this is one:

window.history.go(-1);

Sure you can:

doThrow : Basically used when you want to throw an exception when a method is being called within a mock object.

public void validateEntity(final Object object){}
Mockito.doThrow(IllegalArgumentException.class)
.when(validationService).validateEntity(Matchers.any(AnyObjectClass.class));

doReturn : Used when you want to send back a return value when a method is executed.

public Socket getCosmosSocket() throws IOException {}
Mockito.doReturn(cosmosSocket).when(cosmosServiceImpl).getCosmosSocket();

doAnswer: Sometimes you need to do some actions with the arguments that are passed to the method, for example, add some values, make some calculations or even modify them doAnswer gives you the Answer interface that being executed in the moment that method is called, this interface allows you to interact with the parameters via the InvocationOnMock argument. Also, the return value of answer method will be the return value of the mocked method.

public ReturnValueObject quickChange(Object1 object);
Mockito.doAnswer(new Answer<ReturnValueObject>() {

        @Override
        public ReturnValueObject answer(final InvocationOnMock invocation) throws Throwable {

            final Object1 originalArgument = (invocation.getArguments())[0];
            final ReturnValueObject returnedValue = new ReturnValueObject();
            returnedValue.setCost(new Cost());

            return returnedValue ;
        }
}).when(priceChangeRequestService).quickCharge(Matchers.any(Object1.class));

doNothing: Is the easiest of the list, basically it tells Mockito to do nothing when a method in a mock object is called. Sometimes used in void return methods or method that does not have side effects, or are not related to the unit testing you are doing.

public void updateRequestActionAndApproval(final List<Object1> cmItems);

Mockito.doNothing().when(pagLogService).updateRequestActionAndApproval(
                Matchers.any(Object1.class));

In case you are using Silex add the Symfony Asset as a dependency:

composer require symfony/asset

Then you may register Asset Service Provider:

$app->register(new Silex\Provider\AssetServiceProvider(), array(
    'assets.version' => 'v1',
    'assets.version_format' => '%s?version=%s',
    'assets.named_packages' => array(
        'css' => array(
            'version' => 'css2',
            'base_path' => __DIR__.'/../public_html/resources/css'
        ),
        'images' => array(
            'base_urls' => array(
                'https://img.example.com'
            )
        ),
    ),
));

Then in your Twig template file in head section:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    {% block head %}
    <link rel="stylesheet" href="{{ asset('style.css') }}" />
    {% endblock %}
</head>
<body>

</body>
</html>

I had this issue when I upgraded my project to 4.5 framework and the GridView had Empty Data Template. Something changed and the following statement which previously was returning the Empty Data Template was now returning the Header Row.

GridViewRow dr = (GridViewRow)this.grdViewRoleMembership.Controls[0].Controls[0];

I changed it to below and the error went away and the GridView started working as expected.

GridViewRow dr = (GridViewRow)this.grdViewRoleMembership.Controls[0].Controls[1];

I hope this helps someone.

Dougs answer is correct, but you actually can use $.getJSON and catch errors (not having to use $.ajax). Just chain the getJSON call with a call to the fail function:

$.getJSON('/foo/bar.json')
    .done(function() { alert('request successful'); })
    .fail(function() { alert('request failed'); });

This behavior is part of the jQuery.Deferred interface.
Basically it allows you to attach events to an asynchronous action after you call that action, which means you don't have to pass the event function to the action.

Read more about jQuery.Deferred here: http://api.jquery.com/category/deferred-object/

In my case the easiest way is to instantiate disctionary in your code then you can call keys from it like below

here is my class having dictionary

class Config:

def local(self):
    return {
        "temp_dir": "/tmp/dirtest/",
        "devops": "Mansur",
    }

To instantiate your dictionary

config =  vars.Config()
local_config = config.local()

Finally calling your dictionary keys

patched = local_config.get("devops")

Assume we have a flag, no different from the state or props:

import ComponentOne from './ComponentOne';
import ComponentTwo from './ComponentTwo';

~~~

const Compo = flag ? ComponentOne : ComponentTwo;

~~~

<Compo someProp={someValue} />

With flag Compo fill with one of ComponentOne or ComponentTwo and then the Compo can act like a React Component.

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

Stegmenn nalied it for me but I had one change for when you have an IEnumerbale instead of a string = message like in his example.

private static string GetRoles(IEnumerable<External.Role> roles)
    {
            string[] switchStrings = { "Staff", "Board Member" };
            switch (switchStrings.FirstOrDefault<string>(s => roles.Select(t => t.RoleName).Contains(s)))
            {
                case
                    "Staff":
                    roleNameValues += "Staff,";
                    break;
                case
                    "Board Member":
                    roleNameValues += "Director,";
                    break;
                default:
                    break;
            }

The path-matching strategy, one of 'prefix' or 'full'. Default is 'prefix'.

By default, the router checks URL elements from the left to see if the URL matches a given path, and stops when there is a match. For example, '/team/11/user' matches 'team/:id'.

The path-match strategy 'full' matches against the entire URL. It is important to do this when redirecting empty-path routes. Otherwise, because an empty path is a prefix of any URL, the router would apply the redirect even when navigating to the redirect destination, creating an endless loop.

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

If the response code isn't 200 or 2xx, use getErrorStream() instead of getInputStream().

Table or record locking is available in Access during data writes. You can control the Default record locking through Tools | Options | Advanced tab:

1. No Locks
2. All Records
3. Edited Record

You can set this on a form's Record Locks or in your DAO/ADO code for specific needs.

Transactions shouldn't be a problem if you use them correctly.

Best practice: Separate your tables from All your other code. Give each user their own copy of the code file and then share the data file on a network server. Work on a 'test' copy of the code (and a link to a test data file) and then update user's individual code files separately. If you need to make data file changes (add tables, columns, etc), you will have to have all users get out of the application to make the changes.

See other answers for Oracle comparison.

calling getImageData every time will slow the process ... to speed up things i recommend store image data and then you can get pix value easily and quickly, so do something like this for better performance

// keep it global
let imgData = false;  // initially no image data we have

// create some function block 
if(imgData === false){   
  // fetch once canvas data     
  var ctx = canvas.getContext("2d");
  imgData = ctx.getImageData(0, 0, canvas.width, canvas.height);
}
    // Prepare your X Y coordinates which you will be fetching from your mouse loc
    let x = 100;   // 
    let y = 100;
    // locate index of current pixel
    let index = (y * imgData.width + x) * 4;

        let red = imgData.data[index];
        let green = imgData.data[index+1];
        let blue = imgData.data[index+2];
        let alpha = imgData.data[index+3];
   // Output
   console.log('pix x ' + x +' y '+y+ ' index '+index +' COLOR '+red+','+green+','+blue+','+alpha);

Had the very same problem, then I remembered that for security reasons ASP doesn't expose the entire error or stack trace when accessing your site/service remotely, same as not being able to test a .asmx web service remotely, so I remoted into the sever and monitored my dev tools, and only then did I get the notorious message "Could not load file or assembly 'Newtonsoft.Json, Version=3.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dep...".

So log on the server and debug from there.

in Content script , i add script tag to the head which binds a 'onmessage' handler, inside the handler i use , eval to execute code. In booth content script i use onmessage handler as well , so i get two way communication. Chrome Docs

//Content Script

var pmsgUrl = chrome.extension.getURL('pmListener.js');
$("head").first().append("<script src='"+pmsgUrl+"' type='text/javascript'></script>");


//Listening to messages from DOM
window.addEventListener("message", function(event) {
  console.log('CS :: message in from DOM', event);
  if(event.data.hasOwnProperty('cmdClient')) {
    var obj = JSON.parse(event.data.cmdClient);
    DoSomthingInContentScript(obj);
 }
});

pmListener.js is a post message url listener

//pmListener.js

//Listen to messages from Content Script and Execute Them
window.addEventListener("message", function (msg) {
  console.log("im in REAL DOM");
  if (msg.data.cmnd) {
    eval(msg.data.cmnd);
  }
});

console.log("injected To Real Dom");

This way , I can have 2 way communication between CS to Real Dom. Its very usefull for example if you need to listen webscoket events , or to any in memory variables or events.

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

First of all add jquery library file jquery and call it in your html head.

and then Use jquery based code...

$("#id_of_textbox").keyup(function(event){
    if(event.keyCode == 13){
        $("#id_of_button").click();
    }
});

if you want to do it with pure HTML solution ,you can delete the border in the table if you want...or you can add align="center" attribute to your img tag like this:

<img align="center" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />

see the fiddle : http://jsfiddle.net/Lk2Rh/27/

but still it better to handling this with CSS, i suggest you that.

• I hope this help.

Singleton's half brother

I completely agree with staale and I leave here a sample of creating a singleton half brother:

class void:pass
a = void();
a.__class__ = Singleton

a will report now as being of the same class as singleton even if it does not look like it. So singletons using complicated classes end up depending on we don't mess much with them.

Being so, we can have the same effect and use simpler things like a variable or a module. Still, if we want use classes for clarity and because in Python a class is an object, so we already have the object (not and instance, but it will do just like).

class Singleton:
    def __new__(cls): raise AssertionError # Singletons can't have instances

There we have a nice assertion error if we try to create an instance, and we can store on derivations static members and make changes to them at runtime (I love Python). This object is as good as other about half brothers (you still can create them if you wish), however it will tend to run faster due to simplicity.

You can use 'apply' to run a function or the rows or columns of a matrix or numerical data frame:

cluster1 <- data.frame(a=1:5, b=11:15, c=21:25, d=31:35)

apply(cluster1,2,mean)  # applies function 'mean' to 2nd dimension (columns)

apply(cluster1,1,mean)  # applies function to 1st dimension (rows)

sapply(cluster1, mean)  # also takes mean of columns, treating data frame like list of vectors

You can create tags for GitHub by either using:

• the Git command line, or
• GitHub's web interface.

Creating tags from the command line

To create a tag on your current branch, run this:

git tag <tagname>

If you want to include a description with your tag, add -a to create an annotated tag:

git tag <tagname> -a

This will create a local tag with the current state of the branch you are on. When pushing to your remote repo, tags are NOT included by default. You will need to explicitly say that you want to push your tags to your remote repo:

git push origin --tags

From the official Linux Kernel Git documentation for git push:

--tags

All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line.

Or if you just want to push a single tag:

git push origin <tag>

See also my answer to How do you push a tag to a remote repository using Git? for more details about that syntax above.

Creating tags through GitHub's web interface

You can find GitHub's instructions for this at their Creating Releases help page. Here is a summary:

1. Click the releases link on our repository page,

   

2. Click on Create a new release or Draft a new release,

   

3. Fill out the form fields, then click Publish release at the bottom,

   

4. After you create your tag on GitHub, you might want to fetch it into your local repository too:

   git fetch
   

Now next time, you may want to create one more tag within the same release from website. For that follow these steps:

Go to release tab

1. Click on edit button for the release

2. Provide name of the new tag ABC_DEF_V_5_3_T_2 and hit tab

3. After hitting tab, UI will show this message: Excellent! This tag will be created from the target when you publish this release. Also UI will provide an option to select the branch/commit

4. Select branch or commit

5. Check "This is a pre-release" checkbox for qa tag and uncheck it if the tag is created for Prod tag.

6. After that click on "Update Release"

7. This will create a new Tag within the existing Release.

I had the same problem. My solution was to make all vectors numeric.

For the most part you just set the .val() method. All of the answers are pretty accurate, just wanted to post my results to anyone who may need to set the value via the client id that gets rendered.

 $('#' + '<%= doc_title.ClientID %>').val(null);

Both types are of course associations, and not really mapped strictly to language elements like that. The difference is in the purpose, context, and how the system is modeled.

As a practical example, compare two different types of systems with similar entities:

• A car registration system that primarily keep track of cars, and their owners, etc. Here we are not interested in the engine as a separate entity, but we may still have engine related attributes, like power, and type of fuel. Here the Engine may be a composite part of the car entity.

• A car service shop management system that manages car parts, servicing cars, and replace parts, maybe complete engines. Here we may even have engines stocked and need to keep track of them and other parts separately and independent of the cars. Here the Engine may be an aggregated part of the car entity.

How you implement this in your language is of minor concern since at that level things like readability is much more important.

To answer your extra question:

You can set which rows should be repeated on every page using:

$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);

Now, row 1, 2, 3, 4 and 5 will be repeated.

Got a solution that runs. Don't know if it is optimal though. What I do is to split the string according to http://blogs.oracle.com/aramamoo/2010/05/how_to_split_comma_separated_string_and_pass_to_in_clause_of_select_statement.html

Using:
select regexp_substr(' 1, 2 , 3 ','[^,]+', 1, level) from dual
connect by regexp_substr('1 , 2 , 3 ', '[^,]+', 1, level) is not null;

if you are running Intel processor make sure HAXM (Intel® Hardware Accelerated Execution Manager) installer is install via SDK Manager by checking this option in SDK Manager. and then run the HAXM installer ext via the path below

your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

also check the ram size allocated while doing HAX installation so it fits the ram size of your emulator.

This video shows all the required steps which may help you to solve the problem.

This video will also help you if you face problem after installing HAXM.

Summary of solution:

directory is neither an existing file nor directory. As it turns out, the real name is directory.1 as revealed by ls -la $HOME/Desktop/.

The complete working command is

cp -R $HOME/directory.1/file.bundle /library/application\ support/directory/

with the -R parameter for recursive copy (compulsory for copying directories).

I had the same problem. I had changes in the remote and it was still showing "Already up to date". Recloning the repository fixed the problem for me.

I've made a simple-as-possible extension for that purpose.

extension Array where Element: Equatable {

    func containsHowMany(_ elem: Element) -> Int {
        return reduce(0) { $1 == elem ? $0 + 1 : $0 }
    }

    func duplicatesRemoved() -> Array {
        return self.filter { self.containsHowMany($0) == 1 }
    }

    mutating func removeDuplicates() {
        self = self.duplicatesRemoved(()
    }
}

You can use duplicatesRemoved() to get a new array, whose duplicate elements are removed, or removeDuplicates() to mutate itself. See:

let arr = [1, 1, 1, 2, 2, 3, 4, 5, 6, 6, 6, 6, 6, 7, 8]

let noDuplicates = arr.duplicatesRemoved()
print(arr) // [1, 1, 1, 2, 2, 3, 4, 5, 6, 6, 6, 6, 6, 7, 8]
print(noDuplicates) // [1, 2, 3, 4, 5, 6, 7, 8]

arr.removeDuplicates()
print(arr) // [1, 2, 3, 4, 5, 6, 7, 8]

Try stopping you HMR and hit npm start again to rebuild you project.
This ,made the error to disappear, don't know why.

element.defaultValue will give you the original value.

Please note that this only works on the initial value.

If you are needing this to persist the "old" value every time it changes, an expando property or similar method will meet your needs

java.time

This Answer expands on the Answer by Lockni.

DateTimeFormatter

First define a formatting pattern to match your input string by creating a DateTimeFormatter object.

String input = "Jun 13 2003 23:11:52.454 UTC";
DateTimeFormatter f = DateTimeFormatter.ofPattern ( "MMM d uuuu HH:mm:ss.SSS z" );

ZonedDateTime

Parse the string as a ZonedDateTime. You can think of that class as: ( Instant + ZoneId ).

ZonedDateTime zdt = ZonedDateTime.parse ( "Jun 13 2003 23:11:52.454 UTC" , f );

zdt.toString(): 2003-06-13T23:11:52.454Z[UTC]

Count-from-epoch

I do not recommend tracking date-time values as a count-from-epoch. Doing so makes debugging tricky as humans cannot discern a meaningful date-time from a number so invalid/unexpected values may slip by. Also such counts are ambiguous, in granularity (whole seconds, milli, micro, nano, etc.) and in epoch (at least two dozen in by various computer systems).

But if you insist you can get a count of milliseconds from the epoch of first moment of 1970 in UTC (1970-01-01T00:00:00) through the Instant class. Be aware this means data-loss as you are truncating any nanoseconds to milliseconds.

Instant instant = zdt.toInstant ();

instant.toString(): 2003-06-13T23:11:52.454Z

long millisSinceEpoch = instant.toEpochMilli() ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Instead of killing the window manager, try running the new one with --replace or -replace if available.

You can instantiate a Process instance once for the process you want and keep on tracking the process using that .NET Process object (it will keep on tracking till you call Close on that .NET object explicitly, even if the process it was tracking has died [this is to be able to give you time of process close, aka ExitTime etc.])

Quoting http://msdn.microsoft.com/en-us/library/fb4aw7b8.aspx:

When an associated process exits (that is, when it is shut down by the operation system through a normal or abnormal termination), the system stores administrative information about the process and returns to the component that had called WaitForExit. The Process component can then access the information, which includes the ExitTime, by using the Handle to the exited process.

Because the associated process has exited, the Handle property of the component no longer points to an existing process resource. Instead, the handle can be used only to access the operating system’s information about the process resource. The system is aware of handles to exited processes that have not been released by Process components, so it keeps the ExitTime and Handle information in memory until the Process component specifically frees the resources. For this reason, any time you call Start for a Process instance, call Close when the associated process has terminated and you no longer need any administrative information about it. Close frees the memory allocated to the exited process.

in render() you can conditionally show the JSX or return null as in:

render(){
    return({yourCondition ? <yourComponent /> : null});
}

So before MySQL 8.0 there is no ROW_NUMBER() function. Accpted answer rewritten to support older versions of MySQL:

SET @row_number = 0;
SELECT t.A, t.B, t.C, (@row_number:=@row_number + 1) AS number
FROM dbo.tableZ AS t ORDER BY t.A;

You can use the concept of selector. onFocus removes the hint.

android:hint="Email"

So when TextView has focus, or has user input (i.e. not empty) the hint will not display.

In your controller action rendering the view you could set the As property of your model to true:

model.As = true;
return View(model);

and in your view simply:

@Html.CheckBoxFor(model => model.As);

Now since the As property of the model is set to true, the CheckBoxFor helper will generate a checked checkbox.

In React, the component will re-render (or update) only if the state or the prop changes.

In your case you have to update the state immediately after the change so that the component will re-render with the updates state value.

onTodoChange(event) {
        // update the state
    this.setState({name: event.target.value});
}

You can use position like this to stretch an element across the parent container.

<table style="position: absolute; top: 0; bottom: 0; left: 0; right: 0;">
    <tr style="height: 25%; font-size: 180px;">
        <td>Region</td>
    </tr>
    <tr style="height: 75%; font-size: 540px;">
        <td>100.00%</td>
    </tr>
</table>

The Upload method's HttpPostedFileBase parameter must have the same name as the the file input.

So just change the input to this:

<input type="file" name="file" />

Also, you could find the files in Request.Files:

[HttpPost]
public ActionResult Upload()
{
     if (Request.Files.Count > 0)
     {
         var file = Request.Files[0];

         if (file != null && file.ContentLength > 0)
         {
            var fileName = Path.GetFileName(file.FileName);
            var path = Path.Combine(Server.MapPath("~/Images/"), fileName);
            file.SaveAs(path);
         }
     }

     return RedirectToAction("UploadDocument");
 }

I have done a jQuery plugin that has the same look of jQuery UI Accordion and can keep all tabs\sections open

you can find it here

http://anasnakawa.wordpress.com/2011/01/25/jquery-ui-multi-open-accordion/

works with the same markup

<div id="multiOpenAccordion">
        <h3><a href="#">tab 1</a></h3>
        <div>Lorem ipsum dolor sit amet</div>
        <h3><a href="#">tab 2</a></h3>
        <div>Lorem ipsum dolor sit amet</div>
</div>

Javascript code

$(function(){
        $('#multiOpenAccordion').multiAccordion();
       // you can use a number or an array with active option to specify which tabs to be opened by default:
       $('#multiOpenAccordion').multiAccordion({ active: 1 });
       // OR
       $('#multiOpenAccordion').multiAccordion({ active: [1, 2, 3] });

       $('#multiOpenAccordion').multiAccordion({ active: false }); // no opened tabs
});

UPDATE: the plugin has been updated to support default active tabs option

UPDATE: This plugin is now deprecated.

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

For users of GitHub, this worked for me:

1. In any branch protection rules where you wish to make the change, make sure Allow force pushes is enabled
2. git reset --hard <full_hash_of_commit_to_reset_to>
3. git push --force

This will "correct" the branch history on your local machine and the GitHub server, but anyone who has sync'ed this branch with the server since the bad commit will have the history on their local machine. If they have permission to push to the branch directly then these commits will show right back up when they sync.

All everyone else needs to do is the git reset command from above to "correct" the branch on their local machine. Of course they would need to be wary of any local commits made to this branch after the target hash. Cherry pick/backup and reapply those as necessary, but if you are in a protected branch then the number of people who can commit directly to it is likely limited.

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

Problem Cause:
The problem is that the cell has not been created yet. TableView first calculates the height for row and then populates the data for each row, so the rows array has not been created when heightForRow method gets called. So your app is trying to access a memory location which it does not have the permission to and therefor you get the EXC_BAD_ACCESS message.

How to achieve self sizing TableViewCell in UITableView:
Just set proper constraints for your views contained in TableViewCell's view in StoryBoard. Remember you shouldn't set height constraints to TableViewCell's root view, its height should be properly computable by the height of its subviews -- This is like what you do to set proper constraints for UIScrollView. This way your cells will get different heights according to their subviews. No additional action needed

You could take your entire server-side model and turn it into a Javascript object by doing the following:

var model = @Html.Raw(Json.Encode(Model));

In your case if you just want the FloorPlanSettings object, simply pass the Encode method that property:

var floorplanSettings = @Html.Raw(Json.Encode(Model.FloorPlanSettings));

EDITED ANSWER PER DAVID'S RESPONSE:

Here's a kind of hackish way. I'm guessing there's an easier way. But you could suppress the bar labels and the plot text of the labels by saving the bar positions from barplot and do a little tweaking up and down. Here's an example with the mtcars data set:

x <- barplot(table(mtcars$cyl), xaxt="n")
labs <- paste(names(table(mtcars$cyl)), "cylinders")
text(cex=1, x=x-.25, y=-1.25, labs, xpd=TRUE, srt=45)

You can use the parse static method from Uri

//...
import android.net.Uri;
//...

Uri myUri = Uri.parse("http://stackoverflow.com")

#include <windows.h>

double PCFreq = 0.0;
__int64 CounterStart = 0;

void StartCounter()
{
    LARGE_INTEGER li;
    if(!QueryPerformanceFrequency(&li))
    cout << "QueryPerformanceFrequency failed!\n";

    PCFreq = double(li.QuadPart)/1000.0;

    QueryPerformanceCounter(&li);
    CounterStart = li.QuadPart;
}
double GetCounter()
{
    LARGE_INTEGER li;
    QueryPerformanceCounter(&li);
    return double(li.QuadPart-CounterStart)/PCFreq;
}

int main()
{
    StartCounter();
    Sleep(1000);
    cout << GetCounter() <<"\n";
    return 0;
}

This program should output a number close to 1000 (windows sleep isn't that accurate, but it should be like 999).

The StartCounter() function records the number of ticks the performance counter has in the CounterStart variable. The GetCounter() function returns the number of milliseconds since StartCounter() was last called as a double, so if GetCounter() returns 0.001 then it has been about 1 microsecond since StartCounter() was called.

If you want to have the timer use seconds instead then change

PCFreq = double(li.QuadPart)/1000.0;

to

PCFreq = double(li.QuadPart);

or if you want microseconds then use

PCFreq = double(li.QuadPart)/1000000.0;

But really it's about convenience since it returns a double.

As you can see the evolution is insane, about 560 time faster than reported in 2012.

On my machines and servers, following my numerous experiments, basics for loops are the fastest. This is even clearer using nested loops ($i $j $k..)

It is also the most flexible in usage, and has a better readability from my view.

My utils method for get current date time using Calendar when our minSdkVersion < 26.

fun Date.toString(format: String, locale: Locale = Locale.getDefault()): String {
    val formatter = SimpleDateFormat(format, locale)
    return formatter.format(this)
}

fun getCurrentDateTime(): Date {
    return Calendar.getInstance().time
}

Using

import ...getCurrentDateTime
import ...toString

val date = getCurrentDateTime()
val dateInString = date.toString("yyyy/MM/dd HH:mm:ss")

This is because the original A activity is already being destroyed by the time you start it from B, C or D. Therefore, onCreate will be called in stead of onNewIntent(). One way of solving this is to always destroy the existing A(using FLAG_ACTIVITY_CLEAR_TASK | FLAG_ACTIVITY_NEW_TASK conjunction when startActivity) before starting a new A, so onCreate will always be called, and you put the code of onNewIntent() into onCreate by checking if getIntent() is the intent you started with.

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

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

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

For example:

RUN whoami
RUN su test
RUN whoami

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

If however you do:

RUN whoami
USER test
RUN whoami

You should see root then test.

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

sudo -u test whoami

But it seems better to use the official supported instruction.

How does it work if you only are using visible-md at Col4 instead? Do you use the -lg at all? If not this might work.

<div class="container">

        <div class="col-xs-4 col-sm-2" align="center">
            Col2
        </div>
        <div class="hidden-xs col-sm-6 col-md-5" align="center">
            Col3
        </div>
        <div class="visible-md col-md-3 " align="center">
            Col4
        </div>
        <div class="col-xs-4 col-sm-2 col-md-1" align="center">
            Col5

var myApp = angular.module('myApp',[]);

myApp .directive('myDirective', function ($timeout) {
    return function (scope, element, attr) {

function MyCtrl($scope) {

}

Use $timeout because directive call after dom load so your changes doesn`'t apply

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

For Guzzle 5, 6 and 7 you do it like this:

Unless you have Excel installed on the Server/PC or use an external tool (which is possible without using Excel Interop, see Create Excel (.XLS and .XLSX) file from C#), it will fail. Using the interop requires Excel to be installed.

I think the answer is pretty simple (unless I'm missing something?)

SELECT    
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END AS some_product
FROM some_table
GROUP BY
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END

You can put the CASE STATEMENT in the GROUP BY verbatim (minus the alias column name)

You can also use eval:

FOO=bar eval 'somecommand someargs | somecommand2'

Since this answer with eval doesn't seem to please everyone, let me clarify something: when used as written, with the single quotes, it is perfectly safe. It is good as it will not launch an external process (like the accepted answer) nor will it execute the commands in an extra subshell (like the other answer).

As we get a few regular views, it's probably good to give an alternative to eval that will please everyone, and has all the benefits (and perhaps even more!) of this quick eval “trick”. Just use a function! Define a function with all your commands:

mypipe() {
    somecommand someargs | somecommand2
}

and execute it with your environment variables like this:

FOO=bar mypipe

Adding <validation validateIntegratedModeConfiguration="false"/> addresses the symptom, but is not appropriate for all circumstances. Having ran around this issue a few times, I hope to help others not only overcome the problem but understand it. (Which becomes more and more important as IIS 6 fades into myth and rumor.)

Background:

This issue and the confusion surrounding it started with the introduction of ASP.NET 2.0 and IIS 7. IIS 6 had and continues to have only one pipeline mode, and it is equivalent to what IIS 7+ calls "Classic" mode. The second, newer, and recommended pipeline mode for all applications running on IIS 7+ is called "Integrated" mode.

So, what's the difference? The key difference is how ASP.NET interacts with IIS.

• Classic mode is limited to an ASP.NET pipeline that cannot interact with the IIS pipeline. Essentially a request comes in and if IIS 6/Classic has been told, through server configuration, that ASP.NET can handle it then IIS hands off the request to ASP.NET and moves on. The significance of this can be gleaned from an example. If I were to authorize access to static image files, I would not be able to do it with an ASP.NET module because the IIS 6 pipeline will handle those requests itself and ASP.NET will never see those requests because they were never handed off.* On the other hand, authorizing which users can access a .ASPX page such as a request for Foo.aspx is trivial even in IIS 6/Classic because IIS always hands those requests off to the ASP.NET pipeline. In Classic mode ASP.NET does not know what it hasn't been told and there is a lot that IIS 6/Classic may not be telling it.

• Integrated mode is recommended because ASP.NET handlers and modules can interact directly with the IIS pipeline. No longer does the IIS pipeline simply hand off the request to the ASP.NET pipeline, now it allows ASP.NET code to hook directly into the IIS pipeline and all the requests that hit it. This means that an ASP.NET module can not only observe requests to static image files, but can intercept those requests and take action by denying access, logging the request, etc.

Overcoming the error:

1. If you are running an older application that was originally built for IIS 6, perhaps you moved it to a new server, there may be absolutely nothing wrong with running the application pool of that application in Classic mode. Go ahead you don't have to feel bad.

2. Then again maybe you are giving your application a face-lift or it was chugging along just fine until you installed a 3rd party library via NuGet, manually, or by some other means. In that case it is entirely possible httpHandlers or httpModules have been added to system.web. The outcome is the error that you are seeing because validateIntegratedModeConfiguration defaults true. Now you have two choices:

   1. Remove the httpHandlers and httpModules elements from system.web. There are a couple possible outcomes from this:
      • Everything works fine, a common outcome;
      • Your application continues to complain, there may be a web.config in a parent folder you are inheriting from, consider cleaning up that web.config too;
      • You grow tired of removing the httpHandlers and httpModules that NuGet packages keep adding to system.web, hey do what you need to.
3. If those options do not work or are more trouble than it is worth then I'm not going to tell you that you can't set validateIntegratedModeConfiguration to false, but at least you know what you're doing and why it matters.

Good reads:

• ASP.NET Integration with IIS 7
• HTTP Handlers and HTTP Modules Overview

*Of course there are ways to get all kind of strange things into the ASP.NET pipeline from IIS 6/Classic via incantations like wildcard mappings, if you like that sort of thing.

You can use white-space: pre-line to preserve line breaks in formatting. There is no need to manually insert html elements.

.popover {
    white-space: pre-line;    
}

or add to your html element style="white-space: pre-line;"

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;

An SQLfiddle to test with.

You can use the append() function to insert items into vectors or lists (dataframes are lists). Simply:

df <- data.frame(a=c(1,2), b=c(3,4), c=c(5,6))

df <- as.data.frame(append(df, list(d=df$b+df$c), after=2))

Or, if you want to specify the position by name use which:

df <- as.data.frame(append(df, list(d=df$b+df$c), after=which(names(df)=="b")))

Just simply add or die(mysqli_error($db)); at the end of your query, this will print the mysqli error.

 mysqli_query($db,"INSERT INTO stockdetails (`itemdescription`,`itemnumber`,`sellerid`,`purchasedate`,`otherinfo`,`numberofitems`,`isitdelivered`,`price`) VALUES ('$itemdescription','$itemnumber','$sellerid','$purchasedate','$otherinfo','$numberofitems','$numberofitemsused','$isitdelivered','$price')") or die(mysqli_error($db));

As a side note I'd say you are at risk of mysql injection, check here How can I prevent SQL injection in PHP?. You should really use prepared statements to avoid any risk.

Your redirect URI in your code(keycloak.init) should be the same as the redirect URI set on Keycloak server (client -> Valid Uri)

Your code is fine, just replace the following line:

JSONArray jsonMainArr = new JSONArray(mainJSON.getJSONArray("source"));

with this line:

JSONArray jsonMainArr = mainJSON.getJSONArray("source");

I used dir /s /b /o:n /a:d, and it worked perfectly, just make sure you let the file finish writing, or you'll have an incomplete list.

I created this prototype to prepend elements to parent element.

Node.prototype.prependChild = function (child: Node) {
    this.insertBefore(child, this.firstChild);
    return this;
};

Server-side functions are on the server-side, client-side functions reside on the client. What you can do is you have to set hidden form variable and submit the form, then on page use Page_Load handler you can access value of variable and call the server method.

If you want to get an index about the similarity of the two pictures, I suggest you from the metrics the SSIM index. It is more consistent with the human eye. Here is an article about it: Structural Similarity Index

It is implemented in OpenCV too, and it can be accelerated with GPU: OpenCV SSIM with GPU

Best Practice - use singular. You have a list of items that make up an Enum. Using an item in the list sounds strange when you say Versions.1_0. It makes more sense to say Version.1_0 since there is only one 1_0 Version.

Hope this will help someone.

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

You're gonna need something like:

<h:link outcome="success">
  <f:param name="foo" value="bar"/>
</h:link>

...and...

<f:metadata>
  <f:viewParam name="foo" value="#{bean.foo}"/>
</f:metadata>

Judging from this page, something like this might be easier:

 <managed-bean>
   <managed-bean-name>blog</managed-bean-name>
   <managed-bean-class>com.acme.Blog</managed-bean-class>
   <managed-property>
      <property-name>entryId</property-name>
      <value>#{param['id']}</value>
   </managed-property>
 </managed-bean>

RESTful API (Route):

rtr.route('/testing')
.get((req, res)=>{
    res.render('test')
})
.post((req, res, next)=>{
       res.render('test')
})

AJAX Code:

$(function(){
$('#anyid').on('click', function(e){
    e.preventDefault()
    $.ajax({
        url: '/testing',
        method: 'GET',
        contentType: 'application/json',
        success: function(res){
            console.log('GET Request')
        }
    })
})

$('#anyid').on('submit', function(e){
    e.preventDefault()
    $.ajax({
        url: '/testing',
        method: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({
            info: "put data here to pass in JSON format."
        }),
        success: function(res){
            console.log('POST Request')
        }
    })
})
})

The question is pretty old, but nowadays you can use forEach, which is efficient and will retain the keys as numbers:

let keys = widthRange.map((v,k) => k).filter(i=>i!==undefined))

This loops through widthRange and makes a new array with the value of the keys, and then filters out all sparce slots by only taking the values that are defined.

(Bad idea, but for thorughness: If slot 0 was always empty, that could be shortened to filter(i=>i) or filter(Boolean)

And, it may be less efficient, but the numbers can be cast with let keys = Object.keys(array).map(i=>i*1)

git add -A -n will do what you want. -A adds all untracked files to the repo, -n makes it a dry-run where the add isn't performed but the status output is given listing each file that would have been added.

This question has been answered, but maybe this might someone else coming here.

I also had an issue where this is undefined, when I was foolishly trying to destructure the methods of a class when initialising it:

import MyClass from "./myClass"

// 'this' is not defined here:
const { aMethod } = new MyClass()
aMethod() // error: 'this' is not defined

// So instead, init as you would normally:
const myClass = new MyClass()
myClass.aMethod() // OK

<div id="container">
    <img style="width: 100%; height: 40%;" id="image" src="...">
</div>

I hope this will serve your purpose.

Use the span tag

<style>
    .redText
    {
        color:red;
    }
    .blackText
    {
        color:black;
        font-weight:bold;
    }
</style>

<span class="redText">My Name is:</span>&nbsp;<span class="blackText">Tintincute</span>

It's also a good idea to avoid inline styling. Use a custom CSS class instead.

Do you mean display resolution (eg 72 dots per inch) or pixel dimensions (browser window is currently 1000 x 800 pixels)?

Screen resolution enables you to know how thick a 10 pixel line will be in inches. Pixel dimensions tell you what percentage of the available screen height will be taken up by a 10 pixel wide horizontal line.

There's no way to know the display resolution just from Javascript since the computer itself usually doesn't know the actual dimensions of the screen, just the number of pixels. 72 dpi is the usual guess....

Note that there's a lot of confusion about display resolution, often people use the term instead of pixel resolution, but the two are quite different. See Wikipedia

Of course, you can also measure resolution in dots per cm. There is also the obscure subject of non-square dots. But I digress.

You can initialize an array in one step by writing the elements in [] like this:

array = ['1', '2', '3']

You can add a reference to System.Configuration in your project and then:

using System.Configuration;

then

string sValue = ConfigurationManager.AppSettings["BatchFile"];

with an app.config file like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <appSettings>
       <add key="BatchFile" value="blah.bat" />
   </appSettings>
</configuration>

Assuming you're asking about the common "index hinting" feature found in many databases, PostgreSQL doesn't provide such a feature. This was a conscious decision made by the PostgreSQL team. A good overview of why and what you can do instead can be found here. The reasons are basically that it's a performance hack that tends to cause more problems later down the line as your data changes, whereas PostgreSQL's optimizer can re-evaluate the plan based on the statistics. In other words, what might be a good query plan today probably won't be a good query plan for all time, and index hints force a particular query plan for all time.

As a very blunt hammer, useful for testing, you can use the enable_seqscan and enable_indexscan parameters. See:

• Examining index usage
• enable_ parameters

These are not suitable for ongoing production use. If you have issues with query plan choice, you should see the documentation for tracking down query performance issues. Don't just set enable_ params and walk away.

Unless you have a very good reason for using the index, Postgres may be making the correct choice. Why?

• For small tables, it's faster to do sequential scans.
• Postgres doesn't use indexes when datatypes don't match properly, you may need to include appropriate casts.
• Your planner settings might be causing problems.

I got this message for a different reason -- I submitted an app via Xcode without first creating an App Store Distribution Profile specifically for the app. I believe Xcode automatically uses a wildcard App Store profile if you have one installed. But an app uses Push Notifications requires its own profile.

The fix is to create a new App Store Distribution profile for the app. Then you download it, drag it onto Xcode, and modify your project Build Settings > Code Signing > Release to use the new profile.

It looks like you've just finished step 3. Instead of running a function, you just print out a statement. A function is defined in the following way:

def addstudent():
    print("Student Added.")

then called by writing addstudent().

I would recommend using a while loop for your input. You can define the menu option outside the loop, put the print statement inside the loop, and do while(#valid option is not picked), then put the if statements after the while. Or you can do a while loop and continue the loop if a valid option is not selected.

Additionally, a dictionary is defined in the following way:

my_dict = {key:definition,...}

There are two times when you can update a record through a view:

1. If the view has no joins or procedure calls and selects data from a single underlying table.
2. If the view has an INSTEAD OF INSERT trigger associated with the view.

Generally, you should not rely on being able to perform an insert to a view unless you have specifically written an INSTEAD OF trigger for it. Be aware, there are also INSTEAD OF UPDATE triggers that can be written as well to help perform updates.

I know this is an old question. But i couldnt get the jquery $(this).change() event to fire correctly onSelect. So i went with the following approach to fire the change event via vanilla js.

$('.date').datepicker({
     showOn: 'focus',
     dateFormat: 'mm-dd-yy',
     changeMonth: true,
     changeYear: true,
     onSelect: function() {
         var event;
         if(typeof window.Event == "function"){
             event = new Event('change');
             this.dispatchEvent(event);
         }   else {
             event = document.createEvent('HTMLEvents');
             event.initEvent('change', false, false);
             this.dispatchEvent(event);
         }
     }
});

The Mark Dickinson answer, although complete, didn't work with the float(52.15) case. After some tests, there is the solution that I'm using:

import decimal
        
def value_to_decimal(value, decimal_places):
    decimal.getcontext().rounding = decimal.ROUND_HALF_UP  # define rounding method
    return decimal.Decimal(str(float(value))).quantize(decimal.Decimal('1e-{}'.format(decimal_places)))

(The conversion of the 'value' to float and then string is very important, that way, 'value' can be of the type float, decimal, integer or string!)

Hope this helps anyone.

Issue could be that the Activity have been finished or in progress of finishing.

Add a check isFinishing , and dismiss dialog only when this is false

if (!YourActivity.this.isFinishing() && pDialog != null) {
    pDialog.dismiss();
}

isFinishing : Check to see whether this activity is in the process of finishing,either because you called finish on it or someone else has requested that it finished.

In Python 2.7, simply do:

from collections import OrderedDict
# regular unsorted dictionary
d = {'banana': 3, 'apple':4, 'pear': 1, 'orange': 2}

# dictionary sorted by key
OrderedDict(sorted(d.items(), key=lambda t: t[0]))
OrderedDict([('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)])

# dictionary sorted by value
OrderedDict(sorted(d.items(), key=lambda t: t[1]))
OrderedDict([('pear', 1), ('orange', 2), ('banana', 3), ('apple', 4)])

Change your clean so rm will not complain:

clean:
    rm -f .lambda .lambda_t .activity .activity_t_lambda
