I recommend using the python bindings to OpenImageIO, it's the standard for dealing with various image formats in the vfx world. I've ovten found it more reliable in reading various compression types compared to PIL.

import OpenImageIO as oiio
input = oiio.ImageInput.open ("/path/to/image.tif")

This isn't a "slice", but it is a general solution that doesn't use explicit indexing, and works for the scenario where the sequence in question is anonymous (so you can create and "slice" on the same line, without creating twice and indexing twice): operator.itemgetter

import operator

# Done once and reused
first_and_last = operator.itemgetter(0, -1)

...

first, last = first_and_last(some_list)

You could just inline it as (after from operator import itemgetter for brevity at time of use):

first, last = itemgetter(0, -1)(some_list)

but if you'll be reusing the getter a lot, you can save the work of recreating it (and give it a useful, self-documenting name) by creating it once ahead of time.

Thus, for your specific use case, you can replace:

x, y = a.split("-")[0], a.split("-")[-1]

with:

x, y = itemgetter(0, -1)(a.split("-"))

and split only once without storing the complete list in a persistent name for len checking or double-indexing or the like.

Note that itemgetter for multiple items returns a tuple, not a list, so if you're not just unpacking it to specific names, and need a true list, you'd have to wrap the call in the list constructor.

You need install pysocks , my version is 1.0 and the code works for me:

import socket
import socks
import requests
ip='localhost' # change your proxy's ip
port = 0000 # change your proxy's port
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, ip, port)
socket.socket = socks.socksocket
url = u'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=inurl%E8%A2%8B'
print(requests.get(url).text)

You can't really force the optimizer to do anything, but you can guide it.

I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.

This is cut from wdCalendar where I modified this procedure:

 function BuildDaysAndWeekView(startday, l, events, config)
   ....
        var scrollpos = $("#dvtec").scrollTop();
        gridcontainer.html(html.join(""));
        setTimeout(function() {
            $("#dvtec").scrollTop(scrollpos);
        }, 25);
   ....

Without the delay, it simply did not work.

As said you have to use SVN Check for modification in GUI and tortoiseproc.exe /command:repostatus /path:"<path-to-version-control-file-or-directory>" in CLI to see changes related to the root of the <path-to-version-control-file-or-directory>.

Sadly, but this command won't show ALL local changes, it does show only those changes which are related to the requested directory root. The changes taken separately, like standalone checkouts or orphan external directories in the root subdirectory will be shown as Unversioned or Nested and you might miss to commit/lookup them.

To avoid such condition you have to either call to tortoiseproc.exe /command:repostatus /pathfile:"<path-to-file-with-list-of-items-to-lookup-from>" (see detailed documentation on the command line: https://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-automation.html), or use some 3dparty applications/utilities/scripts to wrap the call.

I has been wrote my own set of scripts for Windows to automate the call from the Total Commander: https://sf.net/p/contools/contools/HEAD/tree/trunk/Scripts/Tools/ToolAdaptors/totalcmd/README_EN.txt (search for TortoiseSVN)

- Opens TortoiseSVN status dialog for a set of WC directories (always opens to show unversioned changes).

Command:   call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:repostatus "%P" %S

- Opens TortoiseSVN commit dialogs for a set of WC directories (opens only if has not empty versioned changes).

Command:   call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:commit "%P" %S

See the README_EN.txt for the latest details (you have to execute the configure.bat before the usage and copy rest of scripts on yourself like call_nowindow.vbs).

I had the same problem but none of the answers above worked. The solution for me was to restore the Manager web application that is bundled with Tomcat.

Topic's premise

There are three distinct aspects in a multilingual site:

• interface translation
• content
• url routing

While they all interconnected in different ways, from CMS point of view they are managed using different UI elements and stored differently. You seem to be confident in your implementation and understanding of the first two. The question was about the latter aspect - "URL Translation? Should we do this or not? and in what way?"

What the URL can be made of?

A very important thing is, don't get fancy with IDN. Instead favor transliteration (also: transcription and romanization). While at first glance IDN seems viable option for international URLs, it actually does not work as advertised for two reasons:

• some browsers will turn the non-ASCII chars like '?' or 'ž' into '%D1%87' and '%C5%BE'
• if user has custom themes, the theme's font is very likely to not have symbols for those letters

I actually tried to IDN approach few years ago in a Yii based project (horrible framework, IMHO). I encountered both of the above mentioned problems before scraping that solution. Also, I suspect that it might be an attack vector.

Available options ... as I see them.

Basically you have two choices, that could be abstracted as:

• http://site.tld/[:query]: where [:query] determines both language and content choice

• http://site.tld/[:language]/[:query]: where [:language] part of URL defines the choice of language and [:query] is used only to identify the content

Query is ? and O ..

Lets say you pick http://site.tld/[:query].

In that case you have one primary source of language: the content of [:query] segment; and two additional sources:

• value $_COOKIE['lang'] for that particular browser
• list of languages in HTTP Accept-Language ^{(1), (2)} header

First, you need to match the query to one of defined routing patterns (if your pick is Laravel, then read here). On successful match of pattern you then need to find the language.

You would have to go through all the segments of the pattern. Find the potential translations for all of those segments and determine which language was used. The two additional sources (cookie and header) would be used to resolve routing conflicts, when (not "if") they arise.

Take for example: http://site.tld/blog/novinka.

That's transliteration of "????, ???????", that in English means approximately "blog", "latest".

As you can already notice, in Russian "????" will be transliterated as "blog". Which means that for the first part of [:query] you (in the best case scenario) will end up with ['en', 'ru'] list of possible languages. Then you take next segment - "novinka". That might have only one language on the list of possibilities: ['ru'].

When the list has one item, you have successfully found the language.

But if you end up with 2 (example: Russian and Ukrainian) or more possibilities .. or 0 possibilities, as a case might be. You will have to use cookie and/or header to find the correct option.

And if all else fails, you pick the site's default language.

Language as parameter

The alternative is to use URL, that can be defined as http://site.tld/[:language]/[:query]. In this case, when translating query, you do not need to guess the language, because at that point you already know which to use.

There is also a secondary source of language: the cookie value. But here there is no point in messing with Accept-Language header, because you are not dealing with unknown amount of possible languages in case of "cold start" (when user first time opens site with custom query).

Instead you have 3 simple, prioritized options:

1. if [:language] segment is set, use it
2. if $_COOKIE['lang'] is set, use it
3. use default language

When you have the language, you simply attempt to translate the query, and if translation fails, use the "default value" for that particular segment (based on routing results).

Isn't here a third option?

Yes, technically you can combine both approaches, but that would complicate the process and only accommodate people who want to manually change URL of http://site.tld/en/news to http://site.tld/de/news and expect the news page to change to German.

But even this case could probable be mitigated using cookie value (which would contain information about previous choice of language), to implement with less magic and hope.

Which approach to use?

As you might already guessed, I would recommend http://site.tld/[:language]/[:query] as the more sensible option.

Also in real word situation you would have 3rd major part in URL: "title". As in name of the product in online shop or headline of article in news site.

Example: http://site.tld/en/news/article/121415/EU-as-global-reserve-currency

In this case '/news/article/121415' would be the query, and the 'EU-as-global-reserve-currency' is title. Purely for SEO purposes.

Can it be done in Laravel?

Kinda, but not by default.

I am not too familiar with it, but from what I have seen, Laravel uses simple pattern-based routing mechanism. To implement multilingual URLs you will probably have to extend core class(es), because multilingual routing need access to different forms of storage (database, cache and/or configuration files).

It's routed. What now?

As a result of all you would end up with two valuable pieces of information: current language and translated segments of query. These values then can be used to dispatch to the class(es) which will produce the result.

Basically, the following URL: http://site.tld/ru/blog/novinka (or the version without '/ru') gets turned into something like

$parameters = [
   'language' => 'ru',
   'classname' => 'blog',
   'method' => 'latest',
];

Which you just use for dispatching:

$instance = new {$parameter['classname']};
$instance->{'get'.$parameters['method']}( $parameters );

.. or some variation of it, depending on the particular implementation.

Yes, that is normal behavior. You basically read to the end of the file the first time (you can sort of picture it as reading a tape), so you can't read any more from it unless you reset it, by either using f.seek(0) to reposition to the start of the file, or to close it and then open it again which will start from the beginning of the file.

If you prefer you can use the with syntax instead which will automatically close the file for you.

e.g.,

with open('baby1990.html', 'rU') as f:
  for line in f:
     print line

once this block is finished executing, the file is automatically closed for you, so you could execute this block repeatedly without explicitly closing the file yourself and read the file this way over again.

Run it on a single command line like so:

powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile 
  -WindowStyle Hidden -Command "Get-AppLockerFileInformation -Directory <folderpath> 
  -Recurse -FileType <type>"

Google c++lint from Google code style guide.

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

Yes, to some degree as detailed here.
The approach I've used (pre-2008) is to do the conversion in the .NET business logic before inserting into the DB.

if you don'y want to import any files you can use this:

with open("Test1.txt", "r") as File1:
St = (' '.join(format(ord(x), 'b') for x in File1.read()))
StrList = St.split(" ")

to convert a text file to binary.

and you can use this to convert it back to string:

StrOrgList = StrOrgMsg.split(" ")


for StrValue in StrOrgList:
    if(StrValue != ""):
        StrMsg += chr(int(str(StrValue),2))
print(StrMsg)

hope that is helpful, i've used this with some custom encryption to send over TCP.

If you want to select particular element use below code

var gridRowData = $("<your grid name>").data("kendoGrid");
var selectedItem = gridRowData.dataItem(gridRowData.select());
var quote = selectedItem["<column name>"];

1.) Create an arraylist of appropriate type, in this case i.e String

2.) Create a JSONObject while passing your string to JSONObject constructor as input

• As JSONObject notation is represented by braces i.e {}
• Where as JSONArray notation is represented by square brackets i.e []

3.) Retrieve JSONArray from JSONObject (created at 2nd step) using "interests" as index.

4.) Traverse JASONArray using loops upto the length of array provided by length() function

5.) Retrieve your JSONObjects from JSONArray using getJSONObject(index) function

6.) Fetch the data from JSONObject using index '"interestKey"'.

Note : JSON parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes (") like this

`"{"key":"value"}"`

should be like this

`"{\"key\":\"value\"}"`

so you can use JSONParser to achieve escaped sequence format for safety as

JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);

Code :

JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";

JSONObject jsonObj = (JSONObject) parser.parse(response);

or

JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> interestList = new ArrayList<String>();

JSONArray jsonArray = jsonObj.getJSONArray("interests");

for(int i = 0 ; i < jsonArray.length() ; i++){
    interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}

Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key so in those cases when you are not sure about the presence of value so use optString, optInt, optBoolean etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value

From docs

Get an optional string associated with a key. It returns the defaultValue if there is no such key.

 public String optString(String key, String defaultValue) {

  String missingKeyValue = json_data.optString("status","N/A");
  // note there is no such key as "status" in response
  // will return "N/A" if no key found 

or To get empty string i.e "" if no key found then simply use

  String missingKeyValue = json_data.optString("status");
  // will return "" if no key found where "" is an empty string

the second argument is the number of decimals.

to take output in MySQL you can use if statement SYNTAX:

the if_true and if_false can be used to verify and to show output as there is no print statement in the MySQL

I don't think you're going to get much faster than dd. The bottleneck is the disk; writing hundreds of GB of data to it is going to take a long time no matter how you do it.

But here's a possibility that might work for your application. If you don't care about the contents of the file, how about creating a "virtual" file whose contents are the dynamic output of a program? Instead of open()ing the file, use popen() to open a pipe to an external program. The external program generates data whenever it's needed. Once the pipe is open, it acts just like a regular file in that the program that opened the pipe can fseek(), rewind(), etc. You'll need to use pclose() instead of close() when you're done with the pipe.

If your application needs the file to be a certain size, it will be up to the external program to keep track of where in the "file" it is and send an eof when the "end" has been reached.

You could also use box-shadow property with higher value of blur and rgba() color to set opacity level. Sounds like a better choice in your case.

box-shadow: 0 30px 40px rgba(0,0,0,.1);

You can use the in place option -i of sed for Linux and Unix:

sed -i 's/[ \t]*$//' "$1"

Be aware the expression will delete trailing t's on OSX (you can use gsed to avoid this problem). It may delete them on BSD too.

If you don't have gsed, here is the correct (but hard-to-read) sed syntax on OSX:

sed -i '' -E 's/[ '$'\t'']+$//' "$1"

Three single-quoted strings ultimately become concatenated into a single argument/expression. There is no concatenation operator in bash, you just place strings one after the other with no space in between.

The $'\t' resolves as a literal tab-character in bash (using ANSI-C quoting), so the tab is correctly concatenated into the expression.

I solved it by using the developer tools for IE7 (its a toolbar) and adding a negative z-index to the container of the div that will be below that the other div.

The question asks: "How can it be done in Python 3?"

Use this construct with Python 3.x:

for item in [1,2,3,4]:
    print(item, " ", end="")

This will generate:

1  2  3  4

See this Python doc for more information:

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

--

Aside:

in addition, the print() function also offers the sep parameter that lets one specify how individual items to be printed should be separated. E.g.,

In [21]: print('this','is', 'a', 'test')  # default single space between items
this is a test

In [22]: print('this','is', 'a', 'test', sep="") # no spaces between items
thisisatest

In [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separation
this--*--is--*--a--*--test

If you want to uniquely identify a row within the table rather than your result set, then you need to look at using something like an IDENTITY column. See "IDENTITY property" in the SQL Server help. SQL Server does not auto-generate an ID for each row in the table as Oracle does, so you have to go to the trouble of creating your own ID column and explicitly fetch it in your query.

EDIT: for dynamic numbering of result set rows see below, but that would probably an equivalent for Oracle's ROWNUM and I assume from all the comments on the page that you want the stuff above. For SQL Server 2005 and later you can use the new Ranking Functions function to achieve dynamic numbering of rows.

For example I do this on a query of mine:

select row_number() over (order by rn_execution_date asc) as 'Row Number', rn_execution_date as 'Execution Date', count(*) as 'Count'
from td.run
where rn_execution_date >= '2009-05-19'
group by rn_execution_date
order by rn_execution_date asc

Will give you:

Row Number  Execution Date           Count
----------  -----------------        -----
1          2009-05-19 00:00:00.000  280
2          2009-05-20 00:00:00.000  269
3          2009-05-21 00:00:00.000  279

There's also an article on support.microsoft.com on dynamically numbering rows.

You could actually use xlsread to accomplish this. After first placing your sample data above in a file 'input_file.csv', here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread:

>> [numData,textData,rawData] = xlsread('input_file.csv')

numData =     % An array of the numeric values from the file

   51.9358    4.1833
   51.9354    4.1841
   51.9352    4.1846
   51.9343    4.1864
   51.9343    4.1864
   51.9341    4.1869


textData =    % A cell array of strings for the text values from the file

    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'


rawData =     % All the data from the file (numeric and text) in a cell array

    'ABC'    [51.9358]    [4.1833]
    'ABC'    [51.9354]    [4.1841]
    'ABC'    [51.9352]    [4.1846]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9341]    [4.1869]

You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite. Here's an example:

index = sqrt(sum(numData.^2,2)) >= 50;  % Find the rows where the point is
                                        %   at a distance of 50 or greater
                                        %   from the origin
xlswrite('output_file.csv',rawData(index,:));  % Write those rows to a new file

When you want to run an executable file from the Command prompt, (cmd.exe), or a batch file, it will:

• Search the current working directory for the executable file.
• Search all locations specified in the %PATH% environment variable for the executable file.

If the file isn't found in either of those options you will need to either:

1. Specify the location of your executable.
2. Change the working directory to that which holds the executable.
3. Add the location to %PATH% by apending it, (recommended only with extreme caution).

You can see which locations are specified in %PATH% from the Command prompt, Echo %Path%.

Because of your reported error we can assume that Mobile.exe is not in the current directory or in a location specified within the %Path% variable, so you need to use 1., 2. or 3..

Examples for 1.

C:\directory_path_without_spaces\My-App\Mobile.exe

or:

"C:\directory path with spaces\My-App\Mobile.exe"

Alternatively you may try:

Start C:\directory_path_without_spaces\My-App\Mobile.exe

or

Start "" "C:\directory path with spaces\My-App\Mobile.exe"

Where "" is an empty title, (you can optionally add a string between those doublequotes).

Examples for 2.

CD /D C:\directory_path_without_spaces\My-App
Mobile.exe

or

CD /D "C:\directory path with spaces\My-App"
Mobile.exe

You could also use the /D option with Start to change the working directory for the executable to be run by the start command

Start /D C:\directory_path_without_spaces\My-App Mobile.exe

or

Start "" /D "C:\directory path with spaces\My-App" Mobile.exe

You need to change the default layout type of top level QWidget object from Break layout type to other layout types (Vertical Layout, Horizontal Layout, Grid Layout, Form Layout). For example:

To something like this:

This: "\0" is a string, not a character. A character uses single quotes, like '\0'.

I just wrote a simple directive (from existing one ofcourse) for a simple uploader in AngularJs.

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

Further to the above excellent comments about trusted constraints:

select * from sys.foreign_keys where is_not_trusted = 1 ;
select * from sys.check_constraints where is_not_trusted = 1 ;

An untrusted constraint, much as its name suggests, cannot be trusted to accurately represent the state of the data in the table right now. It can, however, but can be trusted to check data added and modified in the future.

Additionally, untrusted constraints are disregarded by the query optimiser.

The code to enable check constraints and foreign key constraints is pretty bad, with three meanings of the word "check".

ALTER TABLE [Production].[ProductCostHistory] 
WITH CHECK -- This means "Check the existing data in the table".
CHECK CONSTRAINT -- This means "enable the check or foreign key constraint".
[FK_ProductCostHistory_Product_ProductID] -- The name of the check or foreign key constraint, or "ALL".

Try edtFTPj/PRO, a mature, robust SFTP client library that supports connection pools and asynchronous operations. Also supports FTP and FTPS so all bases for secure file transfer are covered.

You are likely to use in the code a variable named model.

The simplest solution is a join with USING instead of ON. That way, the database "knows" that both id columns are actually the same, and won't nitpick on that:

SELECT id, name, section
  FROM tbl_names
  JOIN tbl_section USING (id)

If id is the only common column name in tbl_names and tbl_section, you can even use a NATURAL JOIN:

SELECT id, name, section
  FROM tbl_names
  NATURAL JOIN tbl_section

You can set your content-type header so clients know to expect json

w.Header().Set("Content-Type", "application/json")

Another way to marshal a struct to json is to build an encoder using the http.ResponseWriter

// get a payload p := Payload{d}
json.NewEncoder(w).Encode(p)

you can use something like this :

string [] filePaths = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);

instead of using "." you can type the name of the file or just the type like "*.txt" also SearchOption.AllDirectories is to search in all subfolders you can change that if you only want one level more about how to use it on here

Before you apply the suggested solution, you can check what is the Unicode character that appeared in your file (and in the error log), in this case 0x90: https://unicodelookup.com/#0x90/1 (or directly at Unicode Consortium site http://www.unicode.org/charts/ by searching 0x0090)

and then consider removing it from the file.

Because some database can throw an exception at dbContextTransaction.Commit() so better this:

using (var context = new BloggingContext()) 
{ 
  using (var dbContextTransaction = context.Database.BeginTransaction()) 
  { 
    try 
    { 
      context.Database.ExecuteSqlCommand( 
          @"UPDATE Blogs SET Rating = 5" + 
              " WHERE Name LIKE '%Entity Framework%'" 
          ); 

      var query = context.Posts.Where(p => p.Blog.Rating >= 5); 
      foreach (var post in query) 
      { 
          post.Title += "[Cool Blog]"; 
      } 

      context.SaveChanges(false); 

      dbContextTransaction.Commit(); 

      context.AcceptAllChanges();
    } 
    catch (Exception) 
    { 
      dbContextTransaction.Rollback(); 
    } 
  } 
} 

res.sendStatus(status) has been added as of version 4.9.0

you can use one of these res.sendStatus() || res.status() methods

below is difference in between res.sendStatus() || res.status()

res.sendStatus(200) // equivalent to res.status(200).send('OK')
res.sendStatus(403) // equivalent to res.status(403).send('Forbidden')
res.sendStatus(404) // equivalent to res.status(404).send('Not Found')
res.sendStatus(500) // equivalent to res.status(500).send('Internal Server Error')

I hope someone finds this helpful thanks

Another, less convenient, way to do it is to use Decimal class:

from decimal import Decimal
pos_inf = Decimal('Infinity')
neg_inf = Decimal('-Infinity')

It can be because you have jpa dependendencies and plugins...

just comment it if not use(build.gradle or pom file)

e. g.

// kotlin("plugin.jpa") version "1.3.61"

// implementation("org.springframework.boot:spring-boot-starter-data-jpa")

For me it issue related to storyboard there is option of ViewController build for set iOS 9.0 and later previously set for iOS 10.0 and later. Actually i want to downgrade the ver from 10 to iOS 9.3.

You could use moment.js with Postman to give you that timestamp format.

You can add this to the pre-request script:

const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));

Then reference {{today}} where ever you need it.

If you add this to the Collection Level Pre-request Script, it will be run for each request in the Collection. Rather than needing to add it to all the requests individually.

For more information about using moment in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

I think the Class on img tag is better when You use the same style in different structure on Your site. You have to decide when you write less line of CSS code and HTML is more readable.

Using jQuery:

$(function() {
    window.isActive = true;
    $(window).focus(function() { this.isActive = true; });
    $(window).blur(function() { this.isActive = false; });
    showIsActive();
});

function showIsActive()
{
    console.log(window.isActive)
    window.setTimeout("showIsActive()", 2000);
}

function doWork()
{
    if (window.isActive) { /* do CPU-intensive stuff */}
}

Actually, the problem is that either /sys/kernel/debug is not mounted, or that the running kernel has no ftrace tracers compiled in so that /sys/kernel/debug/tracing is unavailable. This is the code throwing the error (platform_frameworks_native/libs/utils/Trace.cpp):

void Tracer::init() {
    Mutex::Autolock lock(sMutex);

    if (!sIsReady) {
        add_sysprop_change_callback(changeCallback, 0);

        const char* const traceFileName =
                "/sys/kernel/debug/tracing/trace_marker";
        sTraceFD = open(traceFileName, O_WRONLY);
        if (sTraceFD == -1) {
            ALOGE("error opening trace file: %s (%d)", strerror(errno), errno);
            sEnabledTags = 0;   // no tracing can occur
        } else {
            loadSystemProperty();
        }

        android_atomic_release_store(1, &sIsReady);
    }
}

The log message could definitely be a bit more informative.

Nothing from this examples , works for me

for (var i = 0; i < res.results.length; i++) {
        $('#list_tags').append('<li class="dd-item" id="'+ res.results[i].id + '"><div class="dd-handle root-group">' + res.results[i].name + '</div></li>');
}

    $('.dd-item').click(function () {
    console.log($(this).attr('id'));
    });

To stop that Html5 popup/balloon in Web-kit browser use following CSS

Paxdiablo's definition is really good.

In addition, please consider delivering an uber-jar is sometimes quite useful, if you really want to distribute a software and don't want customer to download dependencies by themselves. As a draw back, if their own policy don't allow usage of some library, or if they have to bind some extra-components (slf4j, system compliant libs, arch specialiez libs, ...) this will probably increase difficulties for them.

You can perform that :

• basically with maven-assembly-plugin
• a bit more further with maven-shade-plugin

A cleaner solution is to provide their library separately; maven-shade-plugin has preconfigured descriptor for that. This is not more complicated to do (with maven and its plugin).

Finally, a really good solution is to use an OSGI Bundle. There is plenty of good tutorials on that :)

For further configuration, please read those topics :

• Should you provide dependent libraries in client jar?
• Best practices in building and deploying Clojure applications: good tutorials?

SUBLIME TEXT

With sublime you just go to

View - > Line Endings -> (select)Unix

Then save the file. Will fix this issue.

Easy as that!

mysqladmin -u root -p password

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

Another option is to use numpy.full, an option available in NumPy 1.8+

a = np.full([height, width, 9], np.nan)

This is pretty flexible and you can fill it with any other number that you want.

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Jsfiddle

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

No for the moment.

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

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

I ran into this situation and creating an extra div was impractical. I ended up just setting the full-height div to height: 10000%; overflow: hidden;

Clearly not the cleanest solution, but it works really fast.

var description=document.getElementsByTagName('h4')[0].innerHTML;
var link = document.createElement('meta');
  
link.setAttribute('name', 'description');
  
link.content = description;
  
document.getElementsByTagName('head')[0].appendChild(link);
var htwo=document.getElementsByTagName('h2');
var hthree=document.getElementsByTagName('h3');
var ls=[];
for(var i=0;i<hthree.length;i++){ls.push(htwo[i].innerHTML);}

for(var i=0;i<hthree.length;i++){ls.push(hthree[i].innerHTML);}

var keyword=ls.toString()
;
var keyw = document.createElement('meta');
  
keyw.setAttribute('name', 'keywords');
  
keyw.content = keyword;
  
document.getElementsByTagName('head')[0].appendChild(keyw);

in my case, I write this code and all my meta tags are working perfectly but we can not see the actual meta tag it will be hidden somewhere.

Android programmers could use BasicNameValuePair

Update:

BasicNameValuePair is now deprecated (API 22). Use Pair instead.

Example usage:

Pair<Integer, String> simplePair = new Pair<>(42, "Second");
Integer first = simplePair.first; // 42
String second = simplePair.second; // "Second"

Boxing and Unboxing are specifically used to treat value-type objects as reference-type; moving their actual value to the managed heap and accessing their value by reference.

Without boxing and unboxing you could never pass value-types by reference; and that means you could not pass value-types as instances of Object.

Try this way.

                var socket = io.connect('http://...');
                console.log(socket.Socket.sessionid);

In my case, I had made a stupid typo in the shebang.

So in case someone else on with fat fingers stumbles across this question:

Whoops: #!/usr/local/bin ruby

I meant to write: #!/usr/bin/env ruby

The vague error ZSH gives sent me down the wrong path:

ZSH: zsh: permission denied: ./foo.rb

Bash: bash: ./foo.rb: /usr/local/bin: bad interpreter: Permission denied

I will give you a better idea

for(decltype(things.size()) i = 0; i < things.size(); i++){
                   //...
}

decltype is

Inspects the declared type of an entity or the type and value category of an expression.

So, It deduces type of things.size() and i will be a type as same as things.size(). So, i < things.size() will be executed without any warning

graph-fs

Install

npm i graph-fs

Use

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

directory.delete(); // <--

If you have GNU find you can also say

find . -newermt '1 minute ago'

The t options makes the reference "file" for newer become a reference date string of the sort that you could pass to GNU date -d, which understands complex date specifications like the one given above.

Try following steps:

1. delete the IISExpress folder as @Yehuda Shapira said
2. restart computer
3. delete the .vs folder in project

Have a good luck!

You want to pass the function object hi to your loop() function, not the result of a call to hi() (which is None since hi() doesn't return anything).

So try this:

>>> loop(hi, 5)
hi
hi
hi
hi
hi

Perhaps this will help you understand better:

>>> print hi()
hi
None
>>> print hi
<function hi at 0x0000000002422648>

remote VisualSVN server 2.5.8 is accessible from at least 3 computers. However on my local computer the url of the repository was not accessible and svn ls https://server-ip:443/svn/project/trunk return error

OPTIONS of 'https://…' could not connect to server (…)

My local computer used to have access to the server. The only thing that was changed was switching to http connection instead of https for Redmine reasons(certificate issue).

I tried different things listed above. What actually solved my problem was installing a new the VisualSVN server 2.5.9 using the same repository. And also Redmine recognized the new repository through https.

Just remember set method to POST in options. Here is my code

var options = {
    url: 'http://www.example.com',
    method: 'POST', // Don't forget this line
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'X-MicrosoftAjax': 'Delta=true', // blah, blah, blah...
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36',
    },
    form: {
        'key-1':'value-1',
        'key-2':'value-2',
        ...
    }
};

//console.log('options:', options);

// Create request to get data
request(options, (err, response, body) => {
    if (err) {
        //console.log(err);
    } else {
        console.log('body:', body);
    }
});

Nested if's in Excel Are ugly:

=If(G2 < 1, .1, IF(G2 < 5,.15,if(G2 < 15,.2,if(G2 < 30,.5,if(G2 < 100,.1,1.3)))))

That should cover it.

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

It happens because Build Tools revision x doesn't exist.

Today, the latest version is 23.0.2 (subject to change all the time).

The buildToolsVersions you want are included in the Android SDK, normally installed in the <sdk>/build-tools/<buildToolsVersion> directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle's buildToolsVersion to some version installed in <sdk>/build-tools

android {
   buildToolsVersion "23.0.2"
   // ...

}

Try this:

CONCATENATE(""""; B2 ;"""")

@widor provided a nice solution alternative too - integrated with mine:

CONCATENATE(char(34); B2 ;char(34))

Personally I like it this way:

DateTime.Now.ToString("yyyy-MM-dd HH.mm.ss")

Because it distinguishes between the date and the time.

The following worked just fine in all scenarios i needed :

"dependencies": {
"GitRepo": "git+https://<token-from-github>:[email protected]/<user>/<GitRepo>.git"
}

for (element in array) {
    console.log(array[element].property);
  }

This works.

I like this approach, it is visual for me.

using (var webClient = new WebClient())
    {
          var response = webClient.DownloadString(url);
          JObject result = JObject.Parse(response);
          var users = result.SelectToken("data");   
          List<User> userList = JsonConvert.DeserializeObject<List<User>>(users.ToString());
    }

include the entire namespace

@model namespace.myclasses.mymodel

In spring framework provides some special type of annotations,called stereotype annotations. These are following:-

@RestController- Declare at controller level.
@Controller – Declare at controller level.
@Component – Declare at Bean/entity level.
@Repository – Declare at DAO level.
@Service – Declare at BO level.

above declared annotations are special because when we add <context:component-scan> into xxx-servlet.xml file ,spring will automatically create the object of those classes which are annotated with above annotation during context creation/loading phase.

getParentFragmentManager().setFragmentResultListener is the 2020 way of doing this. Your only limitation is to use a bundle to pass the data. Check out the docs for more info and examples.

Some other ways

• Call to getActivity() and cast it to the shared activity between your fragments, then use it as a bridge to pass the data. This solution is highly not recommended because of the cupelling it requires between the activity and the fragments, but it used to be the popular way of doing this back in the KitKat days...
• Use callbacks. Any events mechanism will do. This would be a Java vanilla solution. The benefit over FragmentManager is that it's not limited to Bundles. The downside, however, is that you may run into edge cases bugs where you mess up the activity life cycle and get exceptions like IllegalStateException when the fragment manager is in the middle of saving state or the activity were destroyed. Also, it does not support cross-processing communication.

Use DateTime.Parse(string):

DateTime dateTime = DateTime.Parse(dateTimeStr);

yes, its possible, run this command:

lets say you have user called thoko

grant select any table, insert any table, delete any table, update any table to thoko;

note: worked on oracle database

#collect is actually an alias for #map. That means the two methods can be used interchangeably, and effect the same behavior.

All of the above answers are wrong because they fail to handle the OPTIONS preflight request, the solution is to override the mux router's interface. See AngularJS $http get request failed with custom header (alllowed in CORS)

func main() {
    r := mux.NewRouter()
    r.HandleFunc("/save", saveHandler)
    http.Handle("/", &MyServer{r})
    http.ListenAndServe(":8080", nil);

}

type MyServer struct {
    r *mux.Router
}

func (s *MyServer) ServeHTTP(rw http.ResponseWriter, req *http.Request) {
    if origin := req.Header.Get("Origin"); origin != "" {
        rw.Header().Set("Access-Control-Allow-Origin", origin)
        rw.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
        rw.Header().Set("Access-Control-Allow-Headers",
            "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization")
    }
    // Stop here if its Preflighted OPTIONS request
    if req.Method == "OPTIONS" {
        return
    }
    // Lets Gorilla work
    s.r.ServeHTTP(rw, req)
}

Create Table:

Create Table EmployeeProfile ( 
    EmpId int, 
    EmpName varchar(50) not null, 
    EmpPhoto varbinary(max) not null ) 
Go

Insert statement:

Insert EmployeeProfile 
   (EmpId, EmpName, EmpPhoto) 
   Select 1001, 'Vadivel', BulkColumn 
   from Openrowset( Bulk 'C:\Image1.jpg', Single_Blob) as EmployeePicture

This Sql Query Working Fine.

It will assign value of v1 to v2 if it is not null, else it will take a default value as zero.

After fiddling around for a while, I figured things out, and am posting them here hoping it will help others.

Intuitively, np.where is like asking "tell me where in this array, entries satisfy a given condition".

>>> a = np.arange(5,10)
>>> np.where(a < 8)       # tell me where in a, entries are < 8
(array([0, 1, 2]),)       # answer: entries indexed by 0, 1, 2

It can also be used to get entries in array that satisfy the condition:

>>> a[np.where(a < 8)] 
array([5, 6, 7])          # selects from a entries 0, 1, 2

When a is a 2d array, np.where() returns an array of row idx's, and an array of col idx's:

>>> a = np.arange(4,10).reshape(2,3)
array([[4, 5, 6],
       [7, 8, 9]])
>>> np.where(a > 8)
(array(1), array(2))

As in the 1d case, we can use np.where() to get entries in the 2d array that satisfy the condition:

>>> a[np.where(a > 8)] # selects from a entries 0, 1, 2

array([9])

Note, when a is 1d, np.where() still returns an array of row idx's and an array of col idx's, but columns are of length 1, so latter is empty array.

When I paste code into Outlook or have sentences containing code or technical syntax I get annoyed by all of the red squiggles that identify spelling errors. If you want Outlook to clear all of the red spellcheck squiggles you can add a button to the Quick Access Toolbar that calls a VBA macro and removes all squiggles from the current document.

I prefer to run this macro separate from my style choice because I often use it on a selection of text that has mixed content.

For syntax highlighting I use the Notepad++ technique already listed by @srujanreddy, though I discovered that the right-click context menu option a bit handier than navigating the Plugins menu.

If you get annoyed by spell check while you are preparing your email you can add a button to your quick access toolbar that will remove the red squiggles from the message body.

When the LinkButton Enabled property is false it just renders a standard hyperlink. When you right click any disabled hyperlink you don't get the option to open in anything.

try

lbnkVidTtile1.Enabled = true;

I'm sorry if I misunderstood. Could I just make sure that you understand the purpose of a LinkButton? It is to give the appearance of a HyperLink but the behaviour of a Button. This means that it will have an anchor tag, but there is JavaScript wired up that performs a PostBack to the page. If you want to link to another page then it is recommended here that you use a standard HyperLink control.

I have just tested Google Geocoder and got the same problem as you have. I noticed I only get the OVER_QUERY_LIMIT status once every 12 requests So I wait for 1 second (that's the minimum delay to wait) It slows down the application but less than waiting 1 second every request

info = getInfos(getLatLng(code)); //In here I call Google API
record(code, info);
generated++; 
if(generated%interval == 0) {
holdOn(delay); // Every x requests, I sleep for 1 second
}

With the basic holdOn method :

private void holdOn(long delay) {
        try {
            Thread.sleep(delay);
        } catch (InterruptedException ex) {
            // ignore
        }
    }

Hope it helps

you could also use $location.$$search.yourparameter

There is an alternative solution that might be adaptable to the RichTextBox oultined in this blog post - it used a trigger to swap out the control template when the use hovers over the control - should help with performance

I like to think of branches as where you're going, tags as where you've been.

A tag feels like a bookmark of a particular important point in the past, such as a version release.

Whereas a branch is a particular path the project is going down, and thus the branch marker advances with you. When you're done you merge/delete the branch (i.e. the marker). Of course, at that point you could choose to tag that commit.

Put in other words, this error is telling you that SQL Server does not know which B to select from the group.

Either you want to select one specific value (e.g. the MIN, SUM, or AVG) in which case you would use the appropriate aggregate function, or you want to select every value as a new row (i.e. including B in the GROUP BY field list).

Consider the following data:

ID  A   B
1   1  13
1   1  79
1   2  13
1   2  13
1   2  42

The query

SELECT A, COUNT(B) AS T1 
FROM T2 
GROUP BY A

would return:

A  T1
1  2
2  3

which is all well and good.

However consider the following (illegal) query, which would produce this error:

SELECT A, COUNT(B) AS T1, B 
FROM T2 
GROUP BY A

And its returned data set illustrating the problem:

A  T1  B
1  2   13? 79? Both 13 and 79 as separate rows? (13+79=92)? ...?
2  3   13? 42? ...?

However, the following two queries make this clear, and will not cause the error:

1. Using an aggregate

   SELECT A, COUNT(B) AS T1, SUM(B) AS B
   FROM T2
   GROUP BY A
   

   would return:

   A  T1  B
   1  2   92
   2  3   68
   

2. Adding the column to the GROUP BY list

   SELECT A, COUNT(B) AS T1, B
   FROM T2
   GROUP BY A, B
   

   would return:

   A  T1  B
   1  1   13
   1  1   79
   2  2   13
   2  1   42
   

Here comes how I'm doing with simplest for loop.

private void copy(final InputStream in, final OutputStream out)
    throws IOException {
    final byte[] b = new byte[8192];
    for (int r; (r = in.read(b)) != -1;) {
        out.write(b, 0, r);
    }
}

In Safari 9.0 and up you can use shrink-to-fit in viewport meta tag as shown below

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">

Assuming you want to throw away any changes you have, first check the output of git status. For any file that says "unmerged" next to it, run git add <unmerged file>. Then follow up with git reset --hard. That will git rid of any local changes except for untracked files.

We had this issue as well. I cannot remember exactly what fixed as we are now functioning as expected... try grouping the controls. I think that was our resolution.

Synchronized normal method equivalent to Synchronized statement (use this)

class A {
    public synchronized void methodA() {
        // all function code
    }

    equivalent to

    public void methodA() {
        synchronized(this) {
             // all function code
        }
    } 
}

Synchronized static method equivalent to Synchronized statement (use class)

class A {
    public static synchronized void methodA() {
        // all function code
    }

    equivalent to

    public void methodA() {
        synchronized(A.class) {
             // all function code
        }
    } 
}

Synchronized statement (using variable)

class A {
    private Object lock1 = new Object();

    public void methodA() {
        synchronized(lock1 ) {
             // all function code
        }
    } 
}

For synchronized, we have both Synchronized Methods and Synchronized Statements. However, Synchronized Methods is similar to Synchronized Statements so we just need to understand Synchronized Statements.

=> Basically, we will have

synchronized(object or class) { // object/class use to provides the intrinsic lock
   // code 
}

Here is 2 think that help understanding synchronized

• Every object/class have an intrinsic lock associated with it.
• When a thread invokes a synchronized statement, it automatically acquires the intrinsic lock for that synchronized statement's object and releases it when the method returns. As long as a thread owns an intrinsic lock, NO other thread can acquire the SAME lock => thread safe.

=> When a thread A invokes synchronized(this){// code 1} => all the block code (inside class) where have synchronized(this) and all synchronized normal method (inside class) is locked because SAME lock. It will execute after thread A unlock ("// code 1" finished).

This behavior is similar to synchronized(a variable){// code 1} or synchronized(class).

SAME LOCK => lock (not depend on which method? or which statements?)

Use synchronized method or synchronized statements?

I prefer synchronized statements because it is more extendable. Example, in future, you only need synchronized a part of method. Example, you have 2 synchronized method and it don't have any relevant to each other, however when a thread run a method, it will block the other method (it can prevent by use synchronized(a variable)).

However, apply synchronized method is simple and the code look simple. For some class, there only 1 synchronized method, or all synchronized methods in the class in relevant to each other => we can use synchronized method to make code shorter and easy to understand

Note

(it not relevant to much to synchronized, it is the different between object and class or none-static and static).

• When you use synchronized or normal method or synchronized(this) or synchronized(non-static variable) it will synchronized base on each object instance.
• When you use synchronized or static method or synchronized(class) or synchronized(static variable) it will synchronized base on class

hi firstly there seems to be many 'errors' in your html where you are missing closing tags, you could try wrapping the contents of your <body> in a fixed width <div style="margin: 0 auto; width: 900px> to achieve what you have done with the body {margin: 0 10% 0 10%}

I just wrote a quick plugin to run a test using your same snippet and it works fine

$.fn.test = function() {
      return this.each(function(){
        var new_id = 5;
        $(this).attr('id',   this.id + '_' + new_id);
        $(this).attr('name', this.name + '_' + new_id);
        $(this).attr('value', 'test');
      });
    };

$(document).ready(function() {
    $('#field_id').test()
});

<body>
  <div id="container">

  <input type="text" name="field_name" id="field_id" value="meh" />
  </div>
</body>

So I can only presume something else is going on in your code. Can you provide some more details?

The <pre> tag in HTML, used with JSON.pretty_generate, will render the JSON pretty in your view. I was so happy when my illustrious boss showed me this:

<% if @data.present? %>
   <pre><%= JSON.pretty_generate(@data) %></pre>
<% end %>

Swift 5:

extension Int {

    func secondsToTime() -> String {

        let (h,m,s) = (self / 3600, (self % 3600) / 60, (self % 3600) % 60)

        let h_string = h < 10 ? "0\(h)" : "\(h)"
        let m_string =  m < 10 ? "0\(m)" : "\(m)"
        let s_string =  s < 10 ? "0\(s)" : "\(s)"

        return "\(h_string):\(m_string):\(s_string)"
    }
}

Usage:

let seconds : Int = 119
print(seconds.secondsToTime()) // Result = "00:01:59"

Using a custom attribute (implemented with a directive) is perhaps the cleanest way. Here's my version, based on @Josh and @sean's suggestions.

angular.module('mymodule', [])

// Click to navigate
// similar to <a href="#/partial"> but hash is not required, 
// e.g. <div click-link="/partial">
.directive('clickLink', ['$location', function($location) {
    return {
        link: function(scope, element, attrs) {
            element.on('click', function() {
                scope.$apply(function() {
                    $location.path(attrs.clickLink);
                });
            });
        }
    }
}]);

It has some useful features, but I'm new to Angular so there's probably room for improvement.

Not really.

Depending on what you actually need, one possibility may be to set o as the prototype of a new object.

var o = {};
(function(x){
    var obj = Object.create( x );
    obj.foo = 'foo';
    obj.bar = 'bar';
})(o);

alert( o.foo ); // undefined

So any properties you add to obj will be not be added to o. Any properties added to obj with the same property name as a property in o will shadow the o property.

Of course, any properties added to o will be available from obj if they're not shadowed, and all objects that have o in the prototype chain will see the same updates to o.

Also, if obj has a property that references another object, like an Array, you'll need to be sure to shadow that object before adding members to the object, otherwise, those members will be added to obj, and will be shared among all objects that have obj in the prototype chain.

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // 'new_value'

Here you can see that because you didn't shadow the Array at baz on o with a baz property on obj, the o.baz Array gets modified.

So instead, you'd need to shadow it first:

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz = [];
    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // undefined

You could convert your wildcard string to a regular expression and use that with String's matches method. Following your example:

String original = "../Test?/sample*.txt";
String regex = original.replace("?", ".?").replace("*", ".*?");

This works for your examples:

Assert.assertTrue("../Test1/sample22b.txt".matches(regex));
Assert.assertTrue("../Test4/sample-spiffy.txt".matches(regex));

And counter-examples:

Assert.assertTrue(!"../Test3/sample2.blah".matches(regex));
Assert.assertTrue(!"../Test44/sample2.txt".matches(regex));

Check this:

// Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog;

// Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeBox = false;

// Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeBox = false;

// Set the start position of the form to the center of the screen.
form1.StartPosition = FormStartPosition.CenterScreen;

// Display the form as a modal dialog box.
form1.ShowDialog();

it doenst work for me but it prints the correct element to the console

this is the code:

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);
    console.log(el); //print element to console
    el.dispatchEvent(ev);
}
click(400, 400);

write.csv(t, "t.csv", row.names=FALSE)

From ?write.csv:

row.names: either a logical value indicating whether the row names of
          ‘x’ are to be written along with ‘x’, or a character vector
          of row names to be written.

public static class CookieHelper
{
    /// <summary>
    /// Checks whether a cookie exists.
    /// </summary>
    /// <param name="cookieCollection">A CookieCollection, such as Response.Cookies.</param>
    /// <param name="name">The cookie name to delete.</param>
    /// <returns>A bool indicating whether a cookie exists.</returns>
    public static bool Exists(this HttpCookieCollection cookieCollection, string name)
    {
        if (cookieCollection == null)
        {
            throw new ArgumentNullException("cookieCollection");
        }

        return cookieCollection[name] != null;
    }
}

Usage:

Request.Cookies.Exists("MyCookie")

You can "cast" to number using the Number constructor..

var number = new Number("8"); // 8 number

You can also call parseInt builtin function:

var number = parseInt("153"); // 153 number

My solution is:

    $.fn.onAutoFillEvent = function (callback) {
        var el = $(this),
            lastText = "",
            maxCheckCount = 10,
            checkCount = 0;

        (function infunc() {
            var text = el.val();

            if (text != lastText) {
                lastText = text;
                callback(el);
            }
            if (checkCount > maxCheckCount) {
                return false;
            }
            checkCount++;
            setTimeout(infunc, 100);
        }());
    };

  $(".group > input").each(function (i, element) {
      var el = $(element);

      el.onAutoFillEvent(
          function () {
              el.addClass('used');
          }
      );
  });

Here's a way to find all the views in every database on your instance:

SELECT TABLE_SCHEMA, TABLE_NAME 
FROM information_schema.tables 
WHERE TABLE_TYPE LIKE 'VIEW';

Use an array for this.

var markers = [];
for (var i = 0; i < coords.length; ++i) {
    markers[i] = "some stuff";
}

[update] -- Well, my own foolishness provides the answer to this one. As it turns out, I was deleting the records from myTable before running the select COUNT statement.

How did I do that and not notice? Glad you asked. I've been testing a sql unit testing platform (tsqlunit, if you're interested) and as part of one of the tests I ran a truncate table statement, then the above. After the unit test is over everything is rolled back, and records are back in myTable. That's why I got a record count outside of my tests.

Sorry everyone...thanks for your help.

Void is an incomplete type which, by definition, can't be an lvalue. That means it can't get assigned a value.

So it also can't hold any value.

Effective January 15, 2020, The Central Repository no longer supports insecure communication over plain HTTP and requires that all requests to the repository are encrypted over HTTPS.

If you're receiving this error, then you need to replace all URL references to Maven Central with their canonical HTTPS counterparts.

We have made the following changes in my project's build.gradle:

Old:

repositories {
   maven { url "http://repo.maven.apache.org/maven2" }
}

New:

repositories {
   maven { url "https://repo.maven.apache.org/maven2" }
}

There is a way more convenient 'percent'-formatting option for the .format() format method:

>>> '{:.1%}'.format(1/3.0)
'33.3%'

      new AsyncRoute({path: '/demo/:demoKey1/:demoKey2', loader: () => {
      return System.import('app/modules/demo/demo').then(m =>m.demoComponent);
       }, name: 'demoPage'}),
       export class demoComponent {
       onClick(){
            this._router.navigate( ['/demoPage', {demoKey1: "123", demoKey2: "234"}]);
          }
        }

As explained, it is not possible to do what I want with JPA, so I employed the hibernate.cascade annotation, with this, the relevant code in the Parent class now looks like this:

@OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, mappedBy = "parent")
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
            org.hibernate.annotations.CascadeType.DELETE,
            org.hibernate.annotations.CascadeType.MERGE,
            org.hibernate.annotations.CascadeType.PERSIST,
            org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
private Set<Child> childs = new HashSet<Child>();

I could not simple use 'ALL' as this would have deleted the parent as well.

I was confused about what 'add' really does. I just read a very enlightening paragraph from the book Git Pro that I'd like to add here, because it clarifies things

“It turns out that Git stages a file exactly as it is when you run the git add command. If you commit now, the version of benchmarks.rb as it was when you last ran the git add command is how it will go into the commit, not the version of the file as it looks in your working directory when you run git commit. If you modify a file after you run git add, you have to run git add again to stage the latest version of the file:”

git push --all

is the canonical way to push everything to a new bare repository.

Another way to do the same thing is to create your new, non-bare repository and then make a bare clone with

git clone --bare

then use

git remote add origin <new-remote-repo>

in the original (non-bare) repository.

To convert a string to lower case in Python, use something like this.

list.append(sentence.lower())

I found this in the first result after searching for "python upper to lower case".

Maybe someone else has this problem at one point. If you use the UglifyJsPlugin in webpack 2 you need to explicitly specify the sourceMap flag. For example:

new webpack.optimize.UglifyJsPlugin({ sourceMap: true })

I solved this by expanding on what @jlmcdonald suggested. I created a directive that would automatically be applied to all input and select elements:

var blurFocusDirective = function () {
    return {
        restrict: 'E',
        require: '?ngModel',
        link: function (scope, elm, attr, ctrl) {
            if (!ctrl) {
                return;
            }

            elm.on('focus', function () {
                elm.addClass('has-focus');

                scope.$apply(function () {
                    ctrl.hasFocus = true;
                });
            });

            elm.on('blur', function () {
                elm.removeClass('has-focus');
                elm.addClass('has-visited');

                scope.$apply(function () {
                    ctrl.hasFocus = false;
                    ctrl.hasVisited = true;
                });
            });

            elm.closest('form').on('submit', function () {
                elm.addClass('has-visited');

                scope.$apply(function () {
                    ctrl.hasFocus = false;
                    ctrl.hasVisited = true;
                });
            });

        }
    };
};

app.directive('input', blurFocusDirective);
app.directive('select', blurFocusDirective);

This will add has-focus and has-visited classes to various elements as the user focuses/visits the elements. You can then add these classes to your CSS rules to show validation errors:

input.has-visited.ng-invalid:not(.has-focus) {
    background-color: #ffeeee;   
}

This works well in that elements still get $invalid properties etc, but the CSS can be used to give the user a better experience.

I update my forked repos with this one line:

git pull https://github.com/forkuser/forkedrepo.git branch

Use this if you dont want to add another remote endpoint to your project, as other solutions posted here.

Don't do this!

Stay away from putting the events inline with the elements! If you don't, you're missing the point of JQuery (or one of the biggest ones at least).

The reason why it's easy to define click() handlers one way and not the other is that the other way is simply not desirable. Since you're just learning JQuery, stick to the convention. Now is not the time in your learning curve for JQuery to decide that everyone else is doing it wrong and you have a better way!

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

To use a ternary operator without else inside of an array or object declaration, you can use the ES6 spread operator, ...():

const cond = false;
const arr = [
  ...(cond ? ['a'] : []),
  'b',
];
    // ['b']

And for objects:

const cond = false;
const obj = {
  ...(cond ? {a: 1} : {}),
  b: 2,
};
    // {b: 2}

Original source

The first one takes two parameters:

parseInt(string, radix)

The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.

If the radix parameter is omitted, JavaScript assumes the following:

• If the string begins with "0x", the
  radix is 16 (hexadecimal)
• If the string begins with "0", the radix is 8 (octal). This feature
  is deprecated
• If the string begins with any other value, the radix is 10 (decimal)

The other function you mentioned takes only one parameter:

Number(object)

The Number() function converts the object argument to a number that represents the object's value.

If the value cannot be converted to a legal number, NaN is returned.

1. Work out what specific properties of a list you want the items to have. Do they need to be indexable? Sliceable? Do they need an .append() method?

2. Look up the abstract base class which describes that particular type in the collections module.

3. Use isinstance:

   isinstance(x, collections.MutableSequence)
   

You might ask "why not just use type(x) == list?" You shouldn't do that, because then you won't support things that look like lists. And part of the Python mentality is duck typing:

I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck

In other words, you shouldn't require that the objects are lists, just that they have the methods you will need. The collections module provides a bunch of abstract base classes, which are a bit like Java interfaces. Any type that is an instance of collections.Sequence, for example, will support indexing.

I think you might be able to use the ExpandProperty parameter of Select-Object.

For example, to get the list of the current directory and just have the Name property displayed, one would do the following:

ls | select -Property Name

This is still returning DirectoryInfo or FileInfo objects. You can always inspect the type coming through the pipeline by piping to Get-Member (alias gm).

ls | select -Property Name | gm

So, to expand the object to be that of the type of property you're looking at, you can do the following:

ls | select -ExpandProperty Name

In your case, you can just do the following to have a variable be an array of strings, where the strings are the Name property:

$objects = ls | select -ExpandProperty Name

Very easy ... outside "span" element with small font and underline, and inside "font" element with bigger font size.

<span style="font-size:1em;text-decoration:underline;">_x000D_
 <span style="font-size:1.5em;">_x000D_
   Text with big font size and thin underline_x000D_
 </span>_x000D_
</span>

Often you need to put more into the manifest than what you get with the -e switch, and in that case, the syntax is:

jar -cvfm myJar.jar myManifest.txt myApp.class

Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include.

Note that the name of the manifest file you supply can be anything, as jar will automatically rename it and put it into the right place within the jar file.

Please read "How to Write Go Code".

Use go build or go install within the package directory, or supply an import path for the package. Do not use file arguments for build or install.

While you can use file arguments for go run, you should build a package instead, usually with go run ., though you should almost always use go install, or go build.

Have you tried plt.tight_layout()?

with plt.tight_layout() without it:

Or: something like this (use add_axes)

left=[0.1,0.3,0.5,0.7]
width=[0.2,0.2, 0.2, 0.2]
rectLS=[]
for x in left:
   for y in left:
       rectLS.append([x, y, 0.2, 0.2])
axLS=[]
fig=plt.figure()
axLS.append(fig.add_axes(rectLS[0]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i],sharey=axLS[-1]))    
axLS.append(fig.add_axes(rectLS[4]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))
axLS.append(fig.add_axes(rectLS[8]))
for i in [5,6,7]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))     
axLS.append(fig.add_axes(rectLS[12]))
for i in [9,10,11]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))

If you don't need to share axes, then simply axLS=map(fig.add_axes, rectLS)

It wasn't working for me either. vbcrlf and Environment.Newline() both had no effect. My problem was that the Placeholder Properties had a Markup type of HTML. When I changed it to None, it worked like a champ!

I looked around for a solution to this for a while. It appears that the JDK doesn't have the Mozilla plugins (which is what Chrome uses) in it's installation. It is only in the JRE installation. There are a couple of DLLs that make up the plugin and they all start with np*

You could always do just:

a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]

a==b    #returns False
a==c    #returns False
a==d    #returns True

I found a article about Logical vs Physical Address in Operating System, which clearly explains about this.

Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically therefore it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a programs perspective. The hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address.

Physical Address identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address. The user program generates the logical address and thinks that the program is running in this logical address but the program needs physical memory for its execution therefore the logical address must be mapped to the physical address bu MMU before they are used. The term Physical Address Space is used for all physical addresses corresponding to the logical addresses in a Logical address space.

I encountered the same issue and was able to fix it by:

1. Copy the folder to another place.
2. Delete .svn from copied folder
3. Right click the original folder and select 'SVN Checkout'
4. If you can't find (3), then your case is different than mine.
5. See if the directory on the REPO-BROWSER is correct. For my case, this was the cause.
6. Check out
7. Get back the files from the copied folder into the original directory.
8. Commit.

If you already committed the changes than you would have to revert changes.

If you didn't commit yet, just do a clean checkout git checkout .

Just go through "View" and select IDE Log. it will show the output.

All you have to do is to delete the "0" in the cells that contain just that and try again. That should work.

The slidingExpiration=true value is basically saying that after every request made, the timer is reset and as long as the user makes a request within the timeout value, he will continue to be authenticated.

This is not correct. The authentication cookie timeout will only be reset if half the time of the timeout has passed.

See for example https://support.microsoft.com/de-ch/kb/910439/en-us or https://itworksonmymachine.wordpress.com/2008/07/17/forms-authentication-timeout-vs-session-timeout/

This is old, but I put exports in my alias for connecting to the db:

alias schema_one.con="PGOPTIONS='--search_path=schema_one' psql -h host -U user -d database etc"

And for another schema:

alias schema_two.con="PGOPTIONS='--search_path=schema_two' psql -h host -U user -d database etc"

I have set the vm argument in WAS server as -Dfile.encoding=UTF-8 to change the servers' default character set.

Despite this question being rather old, I had to deal with a similar warning and wanted to share what I found out.

First of all this is a warning and not an error. So there is no need to worry too much about it. Basically it means, that Tomcat does not know what to do with the source attribute from context.

This source attribute is set by Eclipse (or to be more specific the Eclipse Web Tools Platform) to the server.xml file of Tomcat to match the running application to a project in workspace.

Tomcat generates a warning for every unknown markup in the server.xml (i.e. the source attribute) and this is the source of the warning. You can safely ignore it.

I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:

        ...
        var signature = Get(url); // base64_encoded signature received from server
        var inputtext= "inputtext"; // this is main text signature was created for
        bool result = VerifySignature(inputtext, signature);
        ...

    private bool VerifySignature(string input, string signature)
    {
        var result = false;
        using (var cps=new RSACryptoServiceProvider())
        {
            // converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
            byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
            byte[] signatureBytes  = Convert.FromBase64String(signature);

            cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
            result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes  );
        }

        return result;
    }

Example

<div id="header_id" class="header_class">Text</div>

#header_id {font-color:#fff}
.header_class {font-color:#000}

(Note that CSS uses the prefix # for IDs and . for Classes.)

However color was an HTML 4.01 <font> tag attribute deprecated in HTML 5. In CSS there is no "font-color", the style is color so the above should read:

Example

<div id="header_id" class="header_class">Text</div>

#header_id {color:#fff}
.header_class {color:#000}

The text would be white.

I only needed to uncheck 'Automatically manage signing', check it again, and rebuild.

Both are Creational patterns, to create Object.

1) Factory Pattern - Assume, you have one super class and N number of sub classes. The object is created depends on which parameter/value is passed.

2) Builder pattern - to create complex object.

Ex: Make a Loan Object. Loan could be house loan, car loan ,
    education loan ..etc. Each loan will have different interest rate, amount ,  
    duration ...etc. Finally a complex object created through step by step process.

I'll throw my hat in here:

(as part of a static class, as this snippet is two extensions)

//hex encoding of the hash, in uppercase.
public static string Sha1Hash (this string str)
{
    byte[] data = UTF8Encoding.UTF8.GetBytes (str);
    data = data.Sha1Hash ();
    return BitConverter.ToString (data).Replace ("-", "");
}
// Do the actual hashing
public static byte[] Sha1Hash (this byte[] data)
{
    using (SHA1Managed sha1 = new SHA1Managed ()) {
    return sha1.ComputeHash (data);
}

You should use the -m (mirror) flag, as that takes care to not mess with timestamps and to recurse indefinitely.

wget -m http://example.com/configs/.vim/

If you add the points mentioned by others in this thread, it would be:

wget -m -e robots=off --no-parent http://example.com/configs/.vim/

With ES6 arrow functions, you can further write just one line of concise code (excluding variable declaration).

Eg.:

var isDescending = true; //set to false for ascending
console.log(["8/2/2020","8/1/2020","8/13/2020", "8/2/2020"].sort((a,b) => isDescending ? new Date(b).getTime() - new Date(a).getTime() : new Date(a).getTime() - new Date(b).getTime()));

Since time does not exists with the above dates, the Date object will consider following default time for sorting:

00:00:00

The code will work for both ascending and descending sort. Just change the value of isDescending variable as required.

If you are concerned about the string looking nice you could do this:

    [Range(0, Double.PositiveInfinity)]

This will have a default error message of:

The field SuchAndSuch must be between 0 and Infinity.

We can also rely on custom properties (aka CSS variables) in order to manipulate pseudo-element. We can read in the specification that:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules, can be made conditional with @media and other conditional rules, can be used in HTML’s style attribute, can be read or set using the CSSOM, etc.

Considering this, the idea is to define the custom property within the element and the pseudo-element will simply inherit it; thus we can easily modify it.

1) Using inline style:

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

<div class="box"></div>
<div class="box" style="--color:blue;--content:'I am a blue element'"></div>
<div class="box" style="--color:black"></div>
<div class="box" style="--color:#f0f;--content:'another element'"></div>

2) Using CSS and classes

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

.blue {
  --color:blue;
  --content:'I am a blue element';
}
.black {
  --color:black;
}

<div class="box"></div>
<div class="box black" ></div>
<div class="box blue"></div>

3) Using javascript

document.querySelectorAll('.box')[0].style.setProperty("--color", "blue");
document.querySelectorAll('.box')[1].style.setProperty("--content", "'I am another element'");

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

<div class="box"></div>
<div class="box"></div>

4) Using jQuery

$('.box').eq(0).css("--color", "blue");
/* the css() function with custom properties works only with a jQuery vesion >= 3.x
   with older version we can use style attribute to set the value. Simply pay
   attention if you already have inline style defined! 
*/
$('.box').eq(1).attr("style","--color:#f0f");

.box:before {
  content:"I am a before element";
  color:var(--color, red);
  font-size:25px;
}

<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>

It can also be used with complex values:

.box {
  --c:"content";
  --b:linear-gradient(red,blue);
  --s:20px;
  --p:0 15px;
}

.box:before {
  content: var(--c);
  background:var(--b);
  color:#fff;
  font-size: calc(2 * var(--s) + 5px);
  padding:var(--p);
}

<div class="box"></div>

You may notice that I am considering the syntax var(--c,value) where value is the default value and also called the fallback value.

From the same specification we can read:

The value of a custom property can be substituted into the value of another property with the var() function. The syntax of var() is:

var() = var( <custom-property-name> [, <declaration-value> ]? )

The first argument to the function is the name of the custom property to be substituted. The second argument to the function, if provided, is a fallback value, which is used as the substitution value when the referenced custom property is invalid.

And later:

To substitute a var() in a property’s value:

1. If the custom property named by the first argument to the var() function is animation-tainted, and the var() function is being used in the animation property or one of its longhands, treat the custom property as having its initial value for the rest of this algorithm.
2. If the value of the custom property named by the first argument to the var() function is anything but the initial value, replace the var() function by the value of the corresponding custom property.
3. Otherwise, if the var() function has a fallback value as its second argument, replace the var() function by the fallback value. If there are any var() references in the fallback, substitute them as well.
4. Otherwise, the property containing the var() function is invalid at computed-value time.

If we don't set the custom property OR we set it to initial OR it contains an invalid value then the fallback value will be used. The use of initial can be helpful in case we want to reset a custom property to its default value.

If you want to detect the status of navigation bar wether it is hidden/shown. You can simply use following code to detect -

if self.navigationController?.isNavigationBarHidden{
    print("Show navigation bar")
} else {
    print("hide navigation bar")
}

Well, if you're returning Dogs, you'd do:

public IQueryable<Dog> GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    return from d in db.Dogs
           join b in db.Breeds on d.BreedId equals b.BreedId
           select d;
}

If you want the Breed eager-loaded and not lazy-loaded, just use the appropriate DataLoadOptions construct.

For me the easiest way to go is to use range.

import csv

with open('files/filename.csv') as I:
    reader = csv.reader(I)
    fulllist = list(reader)

# Starting with data skipping header
for item in range(1, len(fulllist)): 
    # Print each row using "item" as the index value
    print (fulllist[item])  

In Angular 8 , ViewChild takes 2 parameters:

Try like this:

@ViewChild('nameInput', { static: false }) nameInputRef: ElementRef;

Explanation:

{ static: false }

If you set static false, the child component ALWAYS gets initialized after the view initialization in time for the ngAfterViewInit/ngAfterContentInit callback functions.

{ static: true}

If you set static true, the child component initialization will take place at the view initialization at ngOnInit

By default you can use { static: false }. If you are creating a dynamic view and want to use the template reference variable, then you should use { static: true}

For more info, you can read this article

Working Demo

In the demo, we will scroll to a div using template reference variable.

 @ViewChild("scrollDiv", { static: true }) scrollTo: ElementRef;

With { static: true }, we can use this.scrollTo.nativeElement in ngOnInit, but with { static: false }, this.scrollTo will be undefined in ngOnInit , so we can access in only in ngAfterViewInit

A php file is run whenever you access it via an HTTP request be it GET,POST, PUT.

You can use JQuery/Ajax to send a request on a button click, or even just change the URL of the browser to navigate to the php address.

Depending on the data sent in the POST/GET you can have a switch statement running a different function.

Specifying Function via GET

You can utilize the code here: How to call PHP function from string stored in a Variable along with a switch statement to automatically call the appropriate function depending on data sent.

So on PHP side you can have something like this:

<?php

//see http://php.net/manual/en/function.call-user-func-array.php how to use extensively
if(isset($_GET['runFunction']) && function_exists($_GET['runFunction']))
call_user_func($_GET['runFunction']);
else
echo "Function not found or wrong input";

function test()
{
echo("test");
}

function hello()
{
echo("hello");
}

?>

and you can make the simplest get request using the address bar as testing:

http://127.0.0.1/test.php?runFunction=hellodddddd

results in:

Function not found or wrong input

http://127.0.0.1/test.php?runFunction=hello

results in:

hello

Sending the Data

GET Request via JQuery

See: http://api.jquery.com/jQuery.get/

$.get("test.cgi", { name: "John"})
.done(function(data) {
  alert("Data Loaded: " + data);

POST Request via JQuery

See: http://api.jquery.com/jQuery.post/

$.post("test.php", { name: "John"} );

GET Request via Javascript location

Just add this function and call it, it will convert List to DataTable.

public static DataTable ToDataTable<T>(List<T> items)
{
        DataTable dataTable = new DataTable(typeof(T).Name);

        //Get all the properties
        PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        foreach (PropertyInfo prop in Props)
        {
            //Defining type of data column gives proper data table 
            var type = (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) ? Nullable.GetUnderlyingType(prop.PropertyType) : prop.PropertyType);
            //Setting column names as Property names
            dataTable.Columns.Add(prop.Name, type);
        }
        foreach (T item in items)
        {
           var values = new object[Props.Length];
           for (int i = 0; i < Props.Length; i++)
           {
                //inserting property values to datatable rows
                values[i] = Props[i].GetValue(item, null);
           }
           dataTable.Rows.Add(values);
      }
      //put a breakpoint here and check datatable
      return dataTable;
}

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.

After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

$("form").submit(function () { return false; }); that will prevent the button from submitting or you can just change the button type to "button" <input type="button"/> instead of <input type="submit"/> Which will only work if this button isn't the only button in this form.

You could try

moment().add(1, 'M').subtract(1, 'day').format('DD-MM-YYYY')

Assuming maven project: Properties file should be in src/main/resources/database folder

jdbc.properties file

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true

ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.

Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.

public interface ServiceMarker {

}

Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker

public interface RepositoryMarker {

}

a.b.c.entities.Student

//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)

(since I ran into this today)

Be careful when using ES2015 fat arrow syntax:

This will fail :

it('accesses the network', done => {

  this.timeout(500); // will not work

  // *this* binding refers to parent function scope in fat arrow functions!
  // i.e. the *this* object of the describe function

  done();
});

EDIT: Why it fails:

As @atoth mentions in the comments, fat arrow functions do not have their own this binding. Therefore, it's not possible for the it function to bind to this of the callback and provide a timeout function.

Bottom line: Don't use arrow functions for functions that need an increased timeout.

I'm surprised no one answered this already:

sudo docker network create persistence_backend

Do this if your both running docker and docker-compose

var depthead = (from s in db.M_Users
                  join m in db.M_User_Types on s.F_User_Type equals m.UserType_Id
                  where m.UserType_Name.ToUpper().Trim().Contains("DEPARTMENT HEAD")
                  select new {s.FullName,s.F_User_Type,s.userId,s.UserCode } 
               ).OrderBy(d => d.userId).ToList();

Model.AvailableDeptHead.Add(new SelectListItem { Text = "Select", Value = "0" });
for (int i = 0; i < depthead.Count; i++)
    Model.AvailableDeptHead.Add(new SelectListItem { Text = depthead[i].UserCode + " - " + depthead[i].FullName, Value = Convert.ToString(depthead[i].userId) });

how about just recasting inside a method that should invoke basically a automatic copy constructor

T t = new T();
T t2 = (T)t;  //eh something like that

        List<myclass> cloneum;
        public void SomeFuncB(ref List<myclass> _mylist)
        {
            cloneum = new List<myclass>();
            cloneum = (List < myclass >) _mylist;
            cloneum.Add(new myclass(3));
            _mylist = new List<myclass>();
        }

seems to work to me

Make a call to the DB searching with myid (Id of the row) and get back specific columns:

var columns = db.Notifications
                .Where(x => x.Id == myid)
                .Select(n => new { n.NotificationTitle, 
                                   n.NotificationDescription, 
                                   n.NotificationOrder });

var inputs = document.getElementById("formId").getElementsByTagName("input");
var inputs = document.forms[1].getElementsByTagName("input");

Update for 2020:

var inputs = document.querySelectorAll("#formId input");

After save new file press

Ctrl-6

This is shortcut to alternate file

If you're getting this error with react native, it may be due to a link to an NPM package that you removed (as it was in my case). After removing references to it in the settings.gradle and build.gradle files, I cleaned and rebuilt and it's as good as new :)

As Rahul stated, it is a common Chrome and an OSX bug. I was having similar issues in the past. In fact I finally got tired of making the 2 [yes I know it is not many] additional clicks when testing a local site for work.

As for a possible workaround to this issue [using Windows], I would using one of the many self signing certificate utilities available.

Recommended Steps:

1. Create a Self Signed Cert
2. Import Certificate into Windows Certificate Manager
3. Import Certificate in Chrome Certificate Manager
   NOTE: Step 3 will resolve the issue experienced once Google addresses the bug...considering the time in has been stale there is no ETA in the foreseeable future.**
   
   As much as I prefer to use Chrome for development, I have found myself in Firefox Developer Edition lately. which does not have this issue.
   
   Hope this helps :)

Old, but maybe useful for readers to have a full example of how use modal.

I do like following ( working example jsfiddle ) :

$('button.btn.btn-success').click(function(event)
{

event.preventDefault();

$.post('getpostcodescript.php', $('form').serialize(), function(data, status, xhr)
    {
        // do something here with response;
        console.info(data);
        console.info(status);
        console.info(xhr);
    })
    .done(function() {
        // do something here if done ;
        alert( "saved" );
    })
    .fail(function() {
        // do something here if there is an error ;
        alert( "error" );
    })
    .always(function() {
        // maybe the good state to close the modal
        alert( "finished" );
        // Set a timeout to hide the element again
        setTimeout(function(){
          $("#myModal").hide();
        }, 3000);
    });
});

To deal easier with modals, I recommend using eModal, which permit to go faster on base use of bootstrap 3 modals.

As "me1" has mentioned you can do this assuming that your version of Windows 7 is either Professional or Ultimate, the PC is on the domain and you have preinstall the Remote Server Administration Tools (Windows6.1-KB958830-x64-RefreshPkg.msu or newer) then you'll be able to do the following:

Step 1. Select "Start", select "Control Panel", select "Programs" and click on "Turn Windows features on or off".

Step 2. Check the following 5 features:

"remote server administration tools>feature administration tools>group policy management tools"

"remote server administration tools>feature administration tools>smtp server tools"

"remote server administration tools>role administration tools>ad ds and ad lds tools>active directory module for windows powershell"

"remote server administration tools>role administration tools>ad ds and ad lds tools>ad ds tools>active directory administrative center"

"remote server administration tools>role administration tools>ad ds and ad lds tools>ad ds tools>ad ds snap-ins and command-line tools"

Step 3. Click "OK".

use pandas.read_csv('CSVFILENAME',header=None,sep=', ')

when trying to read csv data from the link

http://archive.ics.uci.edu/ml/machine-learning-databases/adult/adult.data

I copied the data from the site into my csvfile. It had extra spaces so used sep =', ' and it worked :)

Consider this:

std::string str = "Hello " + "world"; // bad!

Both the rhs and the lhs for operator + are char*s. There is no definition of operator + that takes two char*s (in fact, the language doesn't permit you to write one). As a result, on my compiler this produces a "cannot add two pointers" error (yours apparently phrases things in terms of arrays, but it's the same problem).

Now consider this:

std::string str = "Hello " + std::string("world"); // ok

There is a definition of operator + that takes a const char* as the lhs and a std::string as the rhs, so now everyone is happy.

You can extend this to as long a concatenation chain as you like. It can get messy, though. For example:

std::string str = "Hello " + "there " + std::string("world"); // no good!

This doesn't work because you are trying to + two char*s before the lhs has been converted to std::string. But this is fine:

std::string str = std::string("Hello ") + "there " + "world"; // ok

Because once you've converted to std::string, you can + as many additional char*s as you want.

If that's still confusing, it may help to add some brackets to highlight the associativity rules and then replace the variable names with their types:

((std::string("Hello ") + "there ") + "world");
((string + char*) + char*)

The first step is to call string operator+(string, char*), which is defined in the standard library. Replacing those two operands with their result gives:

((string) + char*)

Which is exactly what we just did, and which is still legal. But try the same thing with:

((char* + char*) + string)

And you're stuck, because the first operation tries to add two char*s.

Moral of the story: If you want to be sure a concatenation chain will work, just make sure one of the first two arguments is explicitly of type std::string.
