Just copy paste below code!

This will print your current taxonomy name and description(optional)

<?php 
   $tax = $wp_query->get_queried_object();
   echo ''. $tax->name . '';
   echo "<br>";
   echo ''. $tax->description .''; 
?>

Go to

\node_modules\metro-config\src\defaults\blacklist.js

and replace this

var sharedBlacklist = [
/node_modules[/\\]react[/\\]dist[/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

to

var sharedBlacklist = [
/node_modules[\/\\]react[\/\\]dist[\/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

This is not a best practice and my recommendation is: downgrade node version into 12.9 OR update metro-config since they are fixing the Node issue.

In my case, The issue was that for UAT environment, API URL will start with Http instead of https. Also, the backend assigns different ports for both Http and https.

for example,

http://10.12.12.31:2001/api/example. - is correct for me

https://10.12.12.31:2002/api/example. - is wrong for me

Because I was using https and 2002 port for hitting the UAT environment. So I am getting could not get any response error in postman.

I got the same error running it on wampserver while trying to create a users table. I found a users.ibd file and after I deleted this file, I ran the migrate command again and it worked. The file on my windows machine was located in wamp/bin/mysql/mysql5.6.12/data/myproject.

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

Try ROW_NUMBER()

http://msdn.microsoft.com/en-us/library/ms186734.aspx

Example:

SELECT
  col1,
  col2,
  ROW_NUMBER() OVER (ORDER BY col1) AS rownum
FROM tbl

Couldn't resist to add another method, using childElementCount. It returns the number of child element nodes from a given parent, so you can loop over it.

for(var i=0, len = parent.childElementCount ; i < len; ++i){
    ... do something with parent.children[i]
    }

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

Don't use scanf() to read strings without specifying a field width. You should also check the return values for errors:

#include <stdio.h>

#define NAME_MAX    80
#define NAME_MAX_S "80"

int main(void)
{
    static char name[NAME_MAX + 1]; // + 1 because of null
    if(scanf("%" NAME_MAX_S "[^\n]", name) != 1)
    {
        fputs("io error or premature end of line\n", stderr);
        return 1;
    }

    printf("Hello %s. Nice to meet you.\n", name);
}

Alternatively, use fgets():

#include <stdio.h>

#define NAME_MAX 80

int main(void)
{
    static char name[NAME_MAX + 2]; // + 2 because of newline and null
    if(!fgets(name, sizeof(name), stdin))
    {
        fputs("io error\n", stderr);
        return 1;
    }

    // don't print newline
    printf("Hello %.*s. Nice to meet you.\n", strlen(name) - 1, name);
}

(4castle's answer is better than the below if you can assume Java >= 9)

You need to create a matcher and use that to iteratively find matches.

 import java.util.regex.Matcher;
 import java.util.regex.Pattern;

 ...

 List<String> allMatches = new ArrayList<String>();
 Matcher m = Pattern.compile("your regular expression here")
     .matcher(yourStringHere);
 while (m.find()) {
   allMatches.add(m.group());
 }

After this, allMatches contains the matches, and you can use allMatches.toArray(new String[0]) to get an array if you really need one.

You can also use MatchResult to write helper functions to loop over matches since Matcher.toMatchResult() returns a snapshot of the current group state.

For example you can write a lazy iterator to let you do

for (MatchResult match : allMatches(pattern, input)) {
  // Use match, and maybe break without doing the work to find all possible matches.
}

by doing something like this:

public static Iterable<MatchResult> allMatches(
      final Pattern p, final CharSequence input) {
  return new Iterable<MatchResult>() {
    public Iterator<MatchResult> iterator() {
      return new Iterator<MatchResult>() {
        // Use a matcher internally.
        final Matcher matcher = p.matcher(input);
        // Keep a match around that supports any interleaving of hasNext/next calls.
        MatchResult pending;

        public boolean hasNext() {
          // Lazily fill pending, and avoid calling find() multiple times if the
          // clients call hasNext() repeatedly before sampling via next().
          if (pending == null && matcher.find()) {
            pending = matcher.toMatchResult();
          }
          return pending != null;
        }

        public MatchResult next() {
          // Fill pending if necessary (as when clients call next() without
          // checking hasNext()), throw if not possible.
          if (!hasNext()) { throw new NoSuchElementException(); }
          // Consume pending so next call to hasNext() does a find().
          MatchResult next = pending;
          pending = null;
          return next;
        }

        /** Required to satisfy the interface, but unsupported. */
        public void remove() { throw new UnsupportedOperationException(); }
      };
    }
  };
}

With this,

for (MatchResult match : allMatches(Pattern.compile("[abc]"), "abracadabra")) {
  System.out.println(match.group() + " at " + match.start());
}

yields

a at 0
b at 1
a at 3
c at 4
a at 5
a at 7
b at 8
a at 10

$('#divname').parent().appendTo($("form:first"));

Using this code solved my problem and it worked in every browser, Internet Explorer 7, Firefox 3, and Google Chrome. I start to love jQuery... It's a cool framework.

I have tested with partial render too, exactly what I was looking for. Great!

<script type="text/javascript">
    function openModalDiv(divname) {
        $('#' + divname).dialog({ autoOpen: false, bgiframe: true, modal: true });
        $('#' + divname).dialog('open');
        $('#' + divname).parent().appendTo($("form:first"));
    }

    function closeModalDiv(divname) {
        $('#' + divname).dialog('close');
    }
</script>
...
...
<input id="Button1" type="button" value="Open 1" onclick="javascript:openModalDiv('Div1');" />
...
...
<div id="Div1" title="Basic dialog" >
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
       <ContentTemplate>
          postback test<br />
          <asp:Button ID="but_OK" runat="server" Text="Send request" /><br />
          <asp:TextBox ID="tb_send" runat="server"></asp:TextBox><br />
          <asp:Label ID="lbl_result" runat="server" Text="prova" BackColor="#ff0000></asp:Label>
        </ContentTemplate>
    <asp:UpdatePanel>
    <input id="Button2" type="button" value="cancel" onclick="javascript:closeModalDiv('Div1');" />
</div>

Anchors will need to be a different display type than their default to take a height. display:inline-block; or display:block;.

Also check on line-height which might be interesting with this.

As of feb 2019 .addEventListener() is not currently work with jQuery .trigger() or .change(), you can test it below using Chrome or Firefox.

txt.addEventListener('input', function() {_x000D_
  console.log('not called?');_x000D_
})_x000D_
$('#txt').val('test').trigger('input');_x000D_
$('#txt').trigger('input');_x000D_
$('#txt').change();

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input type="text" id="txt">

you have to use .dispatchEvent() instead.

txt.addEventListener('input', function() {_x000D_
  console.log('it works!');_x000D_
})_x000D_
$('#txt').val('yes')_x000D_
txt.dispatchEvent(new Event('input'));

If you use apache tomcat 8.0 version, instead of it, use tomcat 7.0 I had tried localhost to 127.0.0.1 and power off firewall but not working, but use tomcat 7.0 and now working

If the types of the parameters are all the same (varchar2 for example), you can have a package like this which will do the following:

CREATE OR REPLACE PACKAGE testuser.test_pkg IS

   TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);

END test_pkg;

CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
   BEGIN
      FOR i IN p_parm.first .. p_parm.last
      LOOP
         dbms_output.put_line(p_parm(i));
      END LOOP;

   END;

END test_pkg;

Then, to call it you'd need to set up the array and pass it:

DECLARE
  l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
  l_array(0) := 'hello';
  l_array(1) := 'there';  

  testuser.test_pkg.your_proc(l_array);
END;
/

Just replacing "Please enter your name" to your desired content would do the job. Am I missing something?

.parent:hover > .child {
    /*do anything with this child*/
}

Allows getting any URL on your system, not just a current one.

import org.springframework.hateoas.mvc.ControllerLinkBuilder
...
ControllerLinkBuilder linkBuilder = ControllerLinkBuilder.linkTo(methodOn(YourController.class).getSomeEntityMethod(parameterId, parameterTwoId))

URI methodUri = linkBuilder.Uri()
String methodUrl = methodUri.getPath()

Recommendation. Do not use user-added REM statements to block batch steps. Use conditional GOTO instead. That way you can predefine and test the steps and options. The users also get much simpler changes and better confidence.

@Echo on
rem Using flags to control command execution

SET ExecuteSection1=0

I had this problem with a Silverlight 5 upgraded from a previous version.

Even re-adding the service reference still gave me an empty Reference.cs

I ended up having to create a brand new project and re-creating the service reference. This is something to try if you've spent more than about half an hour on this. Even if you're determined to fix the original project you may want to try this just to see what happens and then work backwards to try to fix the problem.

I never did figure out exactly what the problem was - but possibly something in the .csproj file wasn't upgraded or some setting went wrong.

Another example using Deferreds to implement a cache for any kind of computation (typically some performance-intensive or long-running tasks):

var ResultsCache = function(computationFunction, cacheKeyGenerator) {
    this._cache = {};
    this._computationFunction = computationFunction;
    if (cacheKeyGenerator)
        this._cacheKeyGenerator = cacheKeyGenerator;
};

ResultsCache.prototype.compute = function() {
    // try to retrieve computation from cache
    var cacheKey = this._cacheKeyGenerator.apply(this, arguments);
    var promise = this._cache[cacheKey];

    // if not yet cached: start computation and store promise in cache 
    if (!promise) {
        var deferred = $.Deferred();
        promise = deferred.promise();
        this._cache[cacheKey] = promise;

        // perform the computation
        var args = Array.prototype.slice.call(arguments);
        args.push(deferred.resolve);
        this._computationFunction.apply(null, args);
    }

    return promise;
};

// Default cache key generator (works with Booleans, Strings, Numbers and Dates)
// You will need to create your own key generator if you work with Arrays etc.
ResultsCache.prototype._cacheKeyGenerator = function(args) {
    return Array.prototype.slice.call(arguments).join("|");
};

Here is an example of using this class to perform some (simulated heavy) calculation:

// The addingMachine will add two numbers
var addingMachine = new ResultsCache(function(a, b, resultHandler) {
    console.log("Performing computation: adding " + a + " and " + b);
    // simulate rather long calculation time by using a 1s timeout
    setTimeout(function() {
        var result = a + b;
        resultHandler(result);
    }, 1000);
});

addingMachine.compute(2, 4).then(function(result) {
    console.log("result: " + result);
});

addingMachine.compute(1, 1).then(function(result) {
    console.log("result: " + result);
});

// cached result will be used
addingMachine.compute(2, 4).then(function(result) {
    console.log("result: " + result);
});

The same underlying cache could be used to cache Ajax requests:

var ajaxCache = new ResultsCache(function(id, resultHandler) {
    console.log("Performing Ajax request for id '" + id + "'");
    $.getJSON('http://jsfiddle.net/echo/jsonp/?callback=?', {value: id}, function(data) {
        resultHandler(data.value);
    });
});

ajaxCache.compute("anID").then(function(result) {
    console.log("result: " + result);
});

ajaxCache.compute("anotherID").then(function(result) {
    console.log("result: " + result);
});

// cached result will be used
ajaxCache.compute("anID").then(function(result) {
    console.log("result: " + result);
});

You can play with the above code in this jsFiddle.

I can see at least three options:

1.

df[:10]

2. Using head

df.head(10)

For negative values of n, this function returns all rows except the last n rows, equivalent to df[:-n] [Source].

3. Using iloc

df.iloc[:10]

you can probably do it like this:

String k = null;
String v = null;
options.put(k,v);

For Mac/Linux;

PYTHONPATH=/foo/bar/baz python somescript.py somecommand

For Windows, setup a wrapper pythonpath.bat;

@ECHO OFF
setlocal
set PYTHONPATH=%1
python %2 %3
endlocal

and call pythonpath.bat script file like;

pythonpath.bat /foo/bar/baz somescript.py somecommand

App.Config is an XML file that is used as a configuration file for your application. In other words, you store inside it any setting that you may want to change without having to change code (and recompiling). It is often used to store connection strings.

See this MSDN article on how to do that.

What is embedded bitcode?

According to docs:

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Update: This phrase in "New Features in Xcode 7" made me to think for a long time that Bitcode is needed for Slicing to reduce app size:

When you archive for submission to the App Store, Xcode will compile your app into an intermediate representation. The App Store will then compile the bitcode down into the 64 or 32 bit executables as necessary.

However that's not true, Bitcode and Slicing work independently: Slicing is about reducing app size and generating app bundle variants, and Bitcode is about certain binary optimizations. I've verified this by checking included architectures in executables of non-bitcode apps and founding that they only include necessary ones.

Bitcode allows other App Thinning component called Slicing to generate app bundle variants with particular executables for particular architectures, e.g. iPhone 5S variant will include only arm64 executable, iPad Mini armv7 and so on.

When to enable ENABLE_BITCODE in new Xcode?

For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS and tvOS apps, bitcode is required.

What happens to the binary when ENABLE_BITCODE is enabled in the new Xcode?

From Xcode 7 reference:

Activating this setting indicates that the target or project should generate bitcode during compilation for platforms and architectures which support it. For Archive builds, bitcode will be generated in the linked binary for submission to the app store. For other builds, the compiler and linker will check whether the code complies with the requirements for bitcode generation, but will not generate actual bitcode.

Here's a couple of links that will help in deeper understanding of Bitcode:

• Bitcode Demystified
• Why I'm not enabling Bitcode

In order to check the absence of physical sockets run:

wmic cpu get SocketDesignation

I had a case where the error was thrown by a

$state.go('');

Which is obvious. I guess this can help someone in future.

Try this:

document.getElementById(target).value = newVal.replace(/^\d+(\.\d{0,2})?$/, "");

In modern, supported browsers, you can simply do that in CSS with -

header{
  position: sticky;
  top: 0;
}

Note: The HTML structure is important while using position: sticky, since it's make the element sticky relative to the parent. And the sticky positioning might not work with a single element made sticky within a parent.

Run the snippet below to check a sample implementation.

main{_x000D_
padding: 0;_x000D_
}_x000D_
header{_x000D_
position: sticky;_x000D_
top:0;_x000D_
padding:40px;_x000D_
background: lightblue;_x000D_
text-align: center;_x000D_
}_x000D_
_x000D_
content > div {_x000D_
height: 50px;_x000D_
}

<main>_x000D_
<header>_x000D_
This is my header_x000D_
</header>_x000D_

Can you load the GUIDs into a scratch table then do a

... WHERE var IN SELECT guid FROM #scratchtable

Capturing and grouping

Capturing group (pattern) creates a group that has capturing property.

A related one that you might often see (and use) is (?:pattern), which creates a group without capturing property, hence named non-capturing group.

A group is usually used when you need to repeat a sequence of patterns, e.g. (\.\w+)+, or to specify where alternation should take effect, e.g. ^(0*1|1*0)$ (^, then 0*1 or 1*0, then $) versus ^0*1|1*0$ (^0*1 or 1*0$).

A capturing group, apart from grouping, will also record the text matched by the pattern inside the capturing group (pattern). Using your example, (.*):, .* matches ABC and : matches :, and since .* is inside capturing group (.*), the text ABC is recorded for the capturing group 1.

Group number

The whole pattern is defined to be group number 0.

Any capturing group in the pattern start indexing from 1. The indices are defined by the order of the opening parentheses of the capturing groups. As an example, here are all 5 capturing groups in the below pattern:

(group)(?:non-capturing-group)(g(?:ro|u)p( (nested)inside)(another)group)(?=assertion)
|     |                       |          | |      |      ||       |     |
1-----1                       |          | 4------4      |5-------5     |
                              |          3---------------3              |
                              2-----------------------------------------2

The group numbers are used in back-reference \n in pattern and $n in replacement string.

^{In other regex flavors (PCRE, Perl), they can also be used in sub-routine calls.}

You can access the text matched by certain group with Matcher.group(int group). The group numbers can be identified with the rule stated above.

^{In some regex flavors (PCRE, Perl), there is a branch reset feature which allows you to use the same number for capturing groups in different branches of alternation.}

Group name

From Java 7, you can define a named capturing group (?<name>pattern), and you can access the content matched with Matcher.group(String name). The regex is longer, but the code is more meaningful, since it indicates what you are trying to match or extract with the regex.

The group names are used in back-reference \k<name> in pattern and ${name} in replacement string.

Named capturing groups are still numbered with the same numbering scheme, so they can also be accessed via Matcher.group(int group).

Internally, Java's implementation just maps from the name to the group number. Therefore, you cannot use the same name for 2 different capturing groups.

I have experienced this problem in some projects with Xcode 9.3.1 and in my case the problem is due to some swift code that for some reason Xcode doesn't like. This problem is hard to solve because is difficult to find what file is causing the problem.

When I have this problem, I removing some files from the Xcode project (removing references) and I try to test if indexing works. My process to do so

1. Remove some files
2. Close Xcode
3. Open Xcode
4. If indexing finish try to rename some method if works probably the files you have removed they have something strange for Xcode.

In my case I had a class definition with a reactive extension in the same file and for some reason Xcode doesn't like it, I moved the reactive extension to another file and now the indexing works fine.

This sql script gives the schema, table name and row count of each table in a database selected:

SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by [TotalRowCount] desc

Ref: https://blog.sqlauthority.com/2017/05/24/sql-server-find-row-count-every-table-database-efficiently/

Another way of doing this:

SELECT  o.NAME TABLENAME,
  i.rowcnt 
FROM sysindexes AS i
  INNER JOIN sysobjects AS o ON i.id = o.id 
WHERE i.indid < 2  AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY i.rowcnt desc

Install ejs template

npm install ejs --save

Refer ejs in app.js

app.set('views', path.join(__dirname, 'views'));`
app.set('view engine', 'ejs');

Create a ejs template in views like views/indes.ejs & use ejs tempalte in router

router.get('/', function(req, res, next) {
    res.render('index', { title: 'Express' });
});

You are most likely looking for the IIS_IUSRS account.

Simply make an object and extract arguments from that object.

let checkIfNumbersAddToTen = function (a, b) {
return new Promise(function (resolve, reject) {
 let c = parseInt(a)+parseInt(b);
 let promiseResolution = {
     c:c,
     d : c+c,
     x : 'RandomString'
 };
 if(c===10){
     resolve(promiseResolution);
 }else {
     reject('Not 10');
 }
});
};

Pull arguments from promiseResolution.

checkIfNumbersAddToTen(5,5).then(function (arguments) {
console.log('c:'+arguments.c);
console.log('d:'+arguments.d);
console.log('x:'+arguments.x);
},function (failure) {
console.log(failure);
});

You can specify the shell to be used by the remote host locally.

echo 'echo "Bash version: ${BASH_VERSION}"' | ssh -q localhost bash

And be careful to (single-)quote the variables you wish to be expanded by the remote host; otherwise variable expansion will be done by your local shell!

# example for local / remote variable expansion
{
echo "[[ $- == *i* ]] && echo 'Interactive' || echo 'Not interactive'" | 
    ssh -q localhost bash
echo '[[ $- == *i* ]] && echo "Interactive" || echo "Not interactive"' | 
    ssh -q localhost bash
}

So, to check if a certain file exists on the remote host you can do the following:

host='localhost'  # localhost as test case
file='~/.bash_history'
if `echo 'test -f '"${file}"' && exit 0 || exit 1' | ssh -q "${host}" sh`; then
#if `echo '[[ -f '"${file}"' ]] && exit 0 || exit 1' | ssh -q "${host}" bash`; then
   echo exists
else
   echo does not exist
fi

I'm also reading an exported file which contains french and German languages. I used Encoding.GetEncoding("iso-8859-1"), true which worked out without any challenges.

As others have stated there is no standard so you should choose one yourself. Here are a couple of things to consider when doing so:

1. If you are using JavaScript to consume JSON then using the same naming convention for properties in both will provide visual consistency and possibly some opportunities for cleaner code re-use.

2. A small reason to avoid kebab-case is that the hyphens may clash visually with - characters that appear in values.

   {
     "bank-balance": -10
   }
   

Is this what you're after?

You have a few options, all varying in "correctness" and ease of use. As always, the right design depends on your needs.

• You could simply create two columns in Ticket, OwnedByUserId and OwnedByGroupId, and have nullable Foreign Keys to each table.

• You could create M:M reference tables enabling both ticket:user and ticket:group relationships. Perhaps in future you will want to allow a single ticket to be owned by multiple users or groups? This design does not enforce that a ticket must be owned by a single entity only.

• You could create a default group for every user and have tickets simply owned by either a true Group or a User's default Group.

• Or (my choice) model an entity that acts as a base for both Users and Groups, and have tickets owned by that entity.

Heres a rough example using your posted schema:

create table dbo.PartyType
(   
    PartyTypeId tinyint primary key,
    PartyTypeName varchar(10)
)

insert into dbo.PartyType
    values(1, 'User'), (2, 'Group');


create table dbo.Party
(
    PartyId int identity(1,1) primary key,
    PartyTypeId tinyint references dbo.PartyType(PartyTypeId),
    unique (PartyId, PartyTypeId)
)

CREATE TABLE dbo.[Group]
(
    ID int primary key,
    Name varchar(50) NOT NULL,
    PartyTypeId as cast(2 as tinyint) persisted,
    foreign key (ID, PartyTypeId) references Party(PartyId, PartyTypeID)
)  

CREATE TABLE dbo.[User]
(
    ID int primary key,
    Name varchar(50) NOT NULL,
    PartyTypeId as cast(1 as tinyint) persisted,
    foreign key (ID, PartyTypeId) references Party(PartyID, PartyTypeID)
)

CREATE TABLE dbo.Ticket
(
    ID int primary key,
    [Owner] int NOT NULL references dbo.Party(PartyId),
    [Subject] varchar(50) NULL
)

I was also facing the same issue with Postman for multipart. I fixed it by doing the following steps:

• Do not select Content-Type in the Headers section.
• In Body tab of Postman you should select form-data and select file type.

It worked for me.

If under "last record" you mean the record which has the latest timestamp value, then try this:

my_query = client.query("
  SELECT TIMESTAMP,
    value,
    card
  FROM my_table
  ORDER BY TIMESTAMP DESC
  LIMIT 1
");

It's downloaded probably because there is not Adobe Reader plug-in installed. In this case, IE (it doesn't matter which version) doesn't know how to render it, and it'll simply download the file (Chrome, for example, has its own embedded PDF renderer).

That said. <iframe> is not best way to display a PDF (do not forget compatibility with mobile browsers, for example Safari). Some browsers will always open that file inside an external application (or in another browser window). Best and most compatible way I found is a little bit tricky but works on all browsers I tried (even pretty outdated):

Keep your <iframe> but do not display a PDF inside it, it'll be filled with an HTML page that consists of an <object> tag. Create an HTML wrapping page for your PDF, it should look like this:

<html>
<body>
    <object data="your_url_to_pdf" type="application/pdf">
        <embed src="your_url_to_pdf" type="application/pdf" />
    </object>
</body>
</html>

Of course, you still need the appropriate plug-in installed in the browser. Also, look at this post if you need to support Safari on mobile devices.

1st. Why nesting <embed> inside <object>? You'll find the answer here on SO. Instead of a nested <embed> tag, you may (should!) provide a custom message for your users (or a built-in viewer, see next paragraph). Nowadays, <object> can be used without worries, and <embed> is useless.

2nd. Why an HTML page? So you can provide a fallback if PDF viewer isn't supported. Internal viewer, plain HTML error messages/options, and so on...

It's tricky to check PDF support so that you may provide an alternate viewer for your customers, take a look at PDF.JS project; it's pretty good but rendering quality - for desktop browsers - isn't as good as a native PDF renderer (I didn't see any difference in mobile browsers because of screen size, I suppose).

The file: URL scheme refers to a file on the client machine. There is no hostname in the file: scheme; you just provide the path of the file. So, the file on your local machine would be file:///~User/2ndFile.html. Notice the three slashes; the hostname part of the URL is empty, so the slash at the beginning of the path immediately follows the double slash at the beginning of the URL. You will also need to expand the user's path; ~ does no expand in a file: URL. So you would need file:///home/User/2ndFile.html (on most Unixes), file:///Users/User/2ndFile.html (on Mac OS X), or file:///C:/Users/User/2ndFile.html (on Windows).

Many browsers, for security reasons, do not allow linking from a file that is loaded from a server to a local file. So, you may not be able to do this from a page loaded via HTTP; you may only be able to link to file: URLs from other local pages.

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

You can follow this answer to see many different ways to process CSV in C++.

In your case, the last call to getline is actually putting the last field of the first line and then all of the remaining lines into the variable genero. This is because there is no space delimiter found up until the end of file. Try changing the space character into a newline instead:

    getline(file, genero, file.widen('\n'));

or more succinctly:

    getline(file, genero);

In addition, your check for file.good() is premature. The last newline in the file is still in the input stream until it gets discarded by the next getline() call for ID. It is at this point that the end of file is detected, so the check should be based on that. You can fix this by changing your while test to be based on the getline() call for ID itself (assuming each line is well formed).

while (getline(file, ID, ',')) {
    cout << "ID: " << ID << " " ; 

    getline(file, nome, ',') ;
    cout << "User: " << nome << " " ;

    getline(file, idade, ',') ;
    cout << "Idade: " << idade << " "  ; 

    getline(file, genero);
    cout << "Sexo: " <<  genero<< " "  ;
}

For better error checking, you should check the result of each call to getline().

The id that got generated for your drop down control in the html will be dynamic one. So use the complete id $('ct100_<Your control id>').val(). It will work.

After installing on kubuntu, I found that my pycharm script in ~/bin/pycharm was just a desktop entry:

[Desktop Entry]                                                                                                                                                                                                 
Version=1.0

Comment=Python IDE for Professional Developers
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-pycharm-ce

Obviously, I could not use this to open anything from the command line:

$ pycharm setup.py
/home/eldond/bin/pycharm_old: line 1: [Desktop: command not found
/home/eldond/bin/pycharm_old: line 4: Community: command not found

But there's a hint in the desktop entry file. Looking in /snap/pycharm-community/, I found /snap/pycharm-community/current/bin/pycharm.sh. I removed ~/bin/pycharm (actually renamed it to have a backup) and then did

ln -s /snap/pycharm-community/current/bin/pycharm.sh pycharm

where again, I found the start of the path by inspecting the desktop entry script I had to start with.

Now I can open files with pycharm from the command line. I don't know what I messed up during install this time; the last two times I've done fresh installs, it's had no trouble.

Use the Git GUI in the Git plugin.

Clone your online repository with the URL which you have.

After cloning, make changes to the files. When you make changes, you can see the number changes. Commit those changes.

Fetch from the remote (to check if anything is updated while you are working).

If the fetch operation gives you an update about the changes in the remote repository, make a pull operation which will update your copy in Visual Studio Code. Otherwise, do not make a pull operation if there aren't any changes in the remote repository.

Push your changes to the upstream remote repository by making a push operation.

myapp.h

{
UIButton *myButton;
}
@property (nonatomic,retain)IBoutlet UIButton *myButton;

myapp.m

@synthesize myButton;

-(IBAction)buttonTitle{
[myButton setTitle:@"Play" forState:UIControlStateNormal];
}

As I had the same question, but didn't find the answer here, I made some tests in order to figure out what the difference actually is. I did this, since I need the encoding for something, which is not URL/URI related.

• encodeURIComponent("A") returns "A", it does not encode "A" to "%41"
• decodeURIComponent("%41") returns "A".
• encodeURI("A") returns "A", it does not encode "A" to "%41"
• decodeURI("%41") returns "A".

-That means both can decode alphanumeric characters, even though they did not encode them. However...

• encodeURIComponent("&") returns "%26".
• decodeURIComponent("%26") returns "&".
• encodeURI("&") returns "&".
• decodeURI("%26") returns "%26".

Even though encodeURIComponent does not encode all characters, decodeURIComponent can decode any value between %00 and %7F.

Note: It appears that if you try to decode a value above %7F (unless it's a unicode value), then your script will fail with an "URI error".

Here is a solution using Guava

private User findUserByName(List<User> userList, final String name) {
    Optional<User> userOptional =
            FluentIterable.from(userList).firstMatch(new Predicate<User>() {
                @Override
                public boolean apply(@Nullable User input) {
                    return input.getName().equals(name);
                }
            });
    return userOptional.isPresent() ? userOptional.get() : null; // return user if found otherwise return null if user name don't exist in user list
}

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(
                    Environment.getExternalStorageDirectory()
                            + "/Robotium-Screenshots/");
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length > 0) {
                    for (int ii = 0; ii < dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                    dirFiles = null;
                }
            }
            // if no directory exists, create new directory to store test
            // results
            if (!directory.exists()) {
                directory.mkdir();
            }
        }// end of SD card checking

add permissions on your manifest.xml

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

Happy coding..

I was looking for a different answer for the question title, so maybe other people will be too.

To set type as an ObjectId (so you may reference author as the author of book, for example), you may do like:

const Book = mongoose.model('Book', {
  author: {
    type: mongoose.Schema.Types.ObjectId, // here you set the author ID
                                          // from the Author colection, 
                                          // so you can reference it
    required: true
  },
  title: {
    type: String,
    required: true
  }
});

     CountDownTimer waitTimer;
     waitTimer = new CountDownTimer(60000, 300) {

       public void onTick(long millisUntilFinished) {
          //called every 300 milliseconds, which could be used to
          //send messages or some other action
       }

       public void onFinish() {
          //After 60000 milliseconds (60 sec) finish current 
          //if you would like to execute something when time finishes          
       }
     }.start();

to stop the timer early:

     if(waitTimer != null) {
         waitTimer.cancel();
         waitTimer = null;
     }

To sum with decimal use this:

In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:

    function findTotal(){
    var arr = document.getElementsByName('qty');
    var tot=0;
    for(var i=0;i<arr.length;i++){
        if(parseFloat(arr[i].value))
            tot += parseFloat(arr[i].value);
    }
    document.getElementById('total').value = tot;
    tot.toFixed(2);
}

Use step=".01" min="0" type="number" in the input filed

Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>

There's actually seven variants of this:

Depending on your viewing application or font, the Bullet Operator may seem very similar to either the Middle Dot or the Bullet.

In Bluetooth, all objects are identified by UUIDs. These include services, characteristics and many other things. Bluetooth maintains a database of assigned numbers for standard objects, and assigns sub-ranges for vendors (that have paid enough for a reservation). You can view this list here:

https://www.bluetooth.com/specifications/assigned-numbers/

If you are implementing a standard service (e.g. a serial port, keyboard, headset, etc.) then you should use that service's standard UUID - that will allow you to be interoperable with devices that you didn't develop.

If you are implementing a custom service, then you should generate unique UUIDs, in order to make sure incompatible third-party devices don't try to use your service thinking it is something else. The easiest way is to generate random ones and then hard-code the result in your application (and use the same UUIDs in the devices that will connect to your service, of course).

You can also use this code in onCreate() method:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

Try following

$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow',
    contentType: 'application/json; charset=utf-8',
    data: { "Operation" : "DeleteRow", 
            "TwitterId" : 1 },
    dataType: 'json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});

OR

$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow&TwitterId=1',
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});

Use double quotes instead of single quotes in JSON object. I think this will solve the issue.

I recommend you to read the following post: AngularJS: "Controller as" or "$scope"?

It describes very well the advantages of using "Controller as" to expose variables over "$scope".

I know you asked specifically about methods and not variables, but I think that it's better to stick to one technique and be consistent with it.

So for my opinion, because of the variables issue discussed in the post, it's better to just use the "Controller as" technique and also apply it to the methods.

One way, using regular expressions:

>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup   20 99  That s ridiculous   '

• \w will match alphanumeric characters and underscores

• [^\w] will match anything that's not alphanumeric or underscore

As described in the API of java.sql.PreparedStatement.setBinaryStream() it is available since 1.6 so it is a JDBC 4.0 API! You use a JDBC 3 Driver so this method is not available!

You'd have to define alphanumerics exactly, but

/^(\w{3,5})$/ 

Should match any digit/character/_ combination of length 3-5.

If you also need the dash, make sure to escape it (\-) add it, like this: :

/^([\w\-]{3,5})$/ 

Also: the ^ anchor means that the sequence has to start at the beginning of the line (character string), and the $ that it ends at the end of the line (character string). So your value string mustn't contain anything else, or it won't match.

Looking at about:config on Firefox 33 on GNU/Linux (Ubuntu), and searching connections I found:

network.http.max-connections: 256

That is likely to answer the part is there any limit to the number of active connections per browser, across all domain

network.http.max-persistent-connections-per-proxy: 32

network.http.max-persistent-connections-per-server: 6

skipped two properties...

network.websocket.max-connections: 200

(interesting, seems like they are not limited per server but have a default value lower than global http connections)

document.cookie = "cookie_name=cookie_value; max-age=31536000; path=/";

Will set the value for a year.

Swift 5

if you have created UIBarButtonItem in Interface Builder and you connected outlet to item and want to bind selector programmatically.

Don't forget to set target and selector.

addAppointmentButton.action = #selector(moveToAddAppointment)
addAppointmentButton.target = self

@objc private func moveToAddAppointment() {
     self.presenter.goToCreateNewAppointment()
}

FWIW,

Poor mans security folder (to protect a public shared folder from little prying eyes ;) )

mkdir -p {0..9}/{0..9}/{0..9}/{0..9}

Now you can put your files in a pin numbered folder. Not exactly waterproof, but it's a barrier for the youngest.

The most famous library to create some GUI in C language is certainly GTK.

With this library you can easily create some buttons (for your example). When a user clicks on the button, a signal is emitted and you can write a handler to do some actions.

Here's how you do it.

First, decorate your list this way:

<div class="p">
<div class="text-bullet-centered">&#8277;</div>
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
</div>
<div class="p">
<div class="text-bullet-centered">&#8277;</div>
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
text text text text text text text text text text text text text text text text 
</div>

Add this CSS:

.p {
    position: relative;
    margin: 20px;
    margin-left: 50px;
}
.text-bullet-centered {
    position: absolute;
    left: -40px;
    top: 50%;
    transform: translate(0%,-50%);
    font-weight: bold;
}

And voila, it works. Resize a window, to see that it indeed works.

As a bonus, you can easily change font and color of bullets, which is very hard to do with normal lists.

.p {_x000D_
  position: relative;_x000D_
  margin: 20px;_x000D_
  margin-left: 50px;_x000D_
}_x000D_
_x000D_
.text-bullet-centered {_x000D_
  position: absolute;_x000D_
  left: -40px;_x000D_
  top: 50%;_x000D_
  transform: translate(0%, -50%);_x000D_
  font-weight: bold;_x000D_
}

<div class="p">_x000D_
  <div class="text-bullet-centered">&#8277;</div>_x000D_
  text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text_x000D_
  text text text text text text text text text text text text text_x000D_
</div>_x000D_
<div class="p">_x000D_
  <div class="text-bullet-centered">&#8277;</div>_x000D_
  text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text_x000D_
  text text text text text text text text text text text text text_x000D_
</div>

Try this:

<mat-select [(ngModel)]="defaultValue">
export class AppComponent {
  defaultValue = 'domain';
}

I think that the best approach is to just create a new instance of a class and than assign the object. Here's what I would do:

public function ($someVO) {

     $someCastVO = new SomeVO();
     $someCastVO = $someVO;
     $someCastVO->SomePropertyInVO = "123";

}

Doing this will give you code hinting in most IDEs and help ensure you are using the correct properties.

I think you can do that with:

window.location = "your_url";

I use Marked 2 on Mac OS X. It supports the following syntax for including other files.

<<[chapters/chapter1.md]
<<[chapters/chapter2.md]
<<[chapters/chapter3.md]
<<[chapters/chapter4.md]

Sadly, you can't feed that to pandoc as it doesn't understand the syntax. However, writing a script to strip the syntax out to construct a pandoc command line is easy enough.

The most fundamental problem of your test application is that you call srand once and then call rand one time and exit.

The whole point of srand function is to initialize the sequence of pseudo-random numbers with a random seed.

It means that if you pass the same value to srand in two different applications (with the same srand/rand implementation) then you will get exactly the same sequence of rand() values read after that in both applications.

However in your example application pseudo-random sequence consists only of one element - the first element of a pseudo-random sequence generated from seed equal to current time of 1 sec precision. What do you expect to see on output then?

Obviously when you happen to run application on the same second - you use the same seed value - thus your result is the same of course (as Martin York already mentioned in a comment to the question).

Actually you should call srand(seed) one time and then call rand() many times and analyze that sequence - it should look random.

EDIT:

Oh I get it. Apparently verbal description is not enough (maybe language barrier or something... :) ).

OK. Old-fashioned C code example based on the same srand()/rand()/time() functions that was used in the question:

#include <stdlib.h>
#include <time.h>
#include <stdio.h>

int main(void)
{
    unsigned long j;
    srand( (unsigned)time(NULL) );

    for( j = 0; j < 100500; ++j )
    {
        int n;

        /* skip rand() readings that would make n%6 non-uniformly distributed
          (assuming rand() itself is uniformly distributed from 0 to RAND_MAX) */
        while( ( n = rand() ) > RAND_MAX - (RAND_MAX-5)%6 )
        { /* bad value retrieved so get next one */ }

        printf( "%d,\t%d\n", n, n % 6 + 1 );
    }

    return 0;
}

^^^ THAT sequence from a single run of the program is supposed to look random.

Please NOTE that I don't recommend to use rand/srand functions in production for the reasons explained below and I absolutely don't recommend to use function time as a random seed for the reasons that IMO already should be quite obvious. Those are fine for educational purposes and to illustrate the point sometimes but for any serious use they are mostly useless.

EDIT2:

When using C or C++ standard library it is important to understand that as of now there is not a single standard function or class producing actually random data definitively (guaranteed by the standard). The only standard tool that approaches this problem is std::random_device that unfortunately still does not provide guarantees of actual randomness.

Depending on the nature of application you should first decide if you really need truly random (unpredictable) data. Notable case when you do most certainly need true randomness is information security - e.g. generating symmetric keys, asymmetric private keys, salt values, security tokens, etc.

However security-grade random numbers is a separate industry worth a separate article.

In most cases Pseudo-Random Number Generator is sufficient - e.g. for scientific simulations or games. In some cases consistently defined pseudo-random sequence is even required - e.g. in games you may choose to generate exactly same maps in runtime to avoid storing lots of data.

The original question and reoccurring multitude of identical/similar questions (and even many misguided "answers" to them) indicate that first and foremost it is important to distinguish random numbers from pseudo-random numbers AND to understand what is pseudo-random number sequence in the first place AND to realize that pseudo-random number generators are NOT used the same way you could use true random number generators.

Intuitively when you request random number - the result returned shouldn't depend on previously returned values and shouldn't depend if anyone requested anything before and shouldn't depend in what moment and by what process and on what computer and from what generator and in what galaxy it was requested. That is what word "random" means after all - being unpredictable and independent of anything - otherwise it is not random anymore, right? With this intuition it is only natural to search the web for some magic spells to cast to get such random number in any possible context.

^^^ THAT kind of intuitive expectations IS VERY WRONG and harmful in all cases involving Pseudo-Random Number Generators - despite being reasonable for true random numbers.

While the meaningful notion of "random number" exists (kind of) - there is no such thing as "pseudo-random number". A Pseudo-Random Number Generator actually produces pseudo-random number sequence.

Pseudo-random sequence is in fact always deterministic (predetermined by its algorithm and initial parameters) i.e. there is actually nothing random about it.

When experts talk about quality of PRNG they actually talk about statistical properties of the generated sequence (and its notable sub-sequences). For example if you combine two high quality PRNGs by using them both in turns - you may produce bad resulting sequence - despite them generating good sequences each separately (those two good sequences may simply correlate to each other and thus combine badly).

Specifically rand()/srand(s) pair of functions provide a singular per-process non-thread-safe(!) pseudo-random number sequence generated with implementation-defined algorithm. Function rand() produces values in range [0, RAND_MAX].

Quote from C11 standard (ISO/IEC 9899:2011):

The srand function uses the argument as a seed for a new sequence of pseudo-random numbers to be returned by subsequent calls to rand. If srand is then called with the same seed value, the sequence of pseudo-random numbers shall be repeated. If rand is called before any calls to srand have been made, the same sequence shall be generated as when srand is first called with a seed value of 1.

Many people reasonably expect that rand() would produce a sequence of semi-independent uniformly distributed numbers in range 0 to RAND_MAX. Well it most certainly should (otherwise it's useless) but unfortunately not only standard doesn't require that - there is even explicit disclaimer that states "there is no guarantees as to the quality of the random sequence produced". In some historical cases rand/srand implementation was of very bad quality indeed. Even though in modern implementations it is most likely good enough - but the trust is broken and not easy to recover. Besides its non-thread-safe nature makes its safe usage in multi-threaded applications tricky and limited (still possible - you may just use them from one dedicated thread).

New class template std::mersenne_twister_engine<> (and its convenience typedefs - std::mt19937/std::mt19937_64 with good template parameters combination) provides per-object pseudo-random number generator defined in C++11 standard. With the same template parameters and the same initialization parameters different objects will generate exactly the same per-object output sequence on any computer in any application built with C++11 compliant standard library. The advantage of this class is its predictably high quality output sequence and full consistency across implementations.

Also there are more PRNG engines defined in C++11 standard - std::linear_congruential_engine<> (historically used as fair quality srand/rand algorithm in some C standard library implementations) and std::subtract_with_carry_engine<>. They also generate fully defined parameter-dependent per-object output sequences.

Modern day C++11 example replacement for the obsolete C code above:

#include <iostream>
#include <chrono>
#include <random>

int main()
{
    std::random_device rd;
    // seed value is designed specifically to make initialization
    // parameters of std::mt19937 (instance of std::mersenne_twister_engine<>)
    // different across executions of application
    std::mt19937::result_type seed = rd() ^ (
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::seconds>(
                std::chrono::system_clock::now().time_since_epoch()
                ).count() +
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::microseconds>(
                std::chrono::high_resolution_clock::now().time_since_epoch()
                ).count() );

    std::mt19937 gen(seed);

    for( unsigned long j = 0; j < 100500; ++j )
    /* ^^^Yes. Generating single pseudo-random number makes no sense
       even if you use std::mersenne_twister_engine instead of rand()
       and even when your seed quality is much better than time(NULL) */    
    {
        std::mt19937::result_type n;
        // reject readings that would make n%6 non-uniformly distributed
        while( ( n = gen() ) > std::mt19937::max() -
                                    ( std::mt19937::max() - 5 )%6 )
        { /* bad value retrieved so get next one */ }

        std::cout << n << '\t' << n % 6 + 1 << '\n';
    }

    return 0;
}

The version of previous code that uses std::uniform_int_distribution<>

#include <iostream>
#include <chrono>
#include <random>

int main()
{
    std::random_device rd;
    std::mt19937::result_type seed = rd() ^ (
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::seconds>(
                std::chrono::system_clock::now().time_since_epoch()
                ).count() +
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::microseconds>(
                std::chrono::high_resolution_clock::now().time_since_epoch()
                ).count() );

    std::mt19937 gen(seed);
    std::uniform_int_distribution<unsigned> distrib(1, 6);

    for( unsigned long j = 0; j < 100500; ++j )
    {
        std::cout << distrib(gen) << ' ';
    }

    std::cout << '\n';
    return 0;
}

Here is a quick example:

public class One {

    /**
     * @param args
     */
    public static void main(String[] args) {

        double a = 4.56777;
        System.out.println( new Float( Math.round(a)) );

    }

}

the result and output will be: 5.0
the closest upper bound Float to the starting value of double a = 4.56777
in this case the use of round is recommended since it takes in double values and provides whole long values

use of onScroll enters infinite loop. onMomentumScrollEnd or onScrollEndDrag can be used instead

Try this:

public void LoadData()
        {
            SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Stocks;Integrated Security=True;Pooling=False");
            SqlDataAdapter sda = new SqlDataAdapter("Select * From [Stocks].[dbo].[product]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            DataGridView1.Rows.Clear();

        foreach (DataRow item in dt.Rows)
        {
            int n = DataGridView1.Rows.Add();
            DataGridView1.Rows[n].Cells[0].Value = item["ProductCode"].ToString();
            DataGridView1.Rows[n].Cells[1].Value = item["Productname"].ToString();
            DataGridView1.Rows[n].Cells[2].Value = item["qty"].ToString();                
            if ((bool)item["productstatus"])
            {
                DataGridView1.Rows[n].Cells[3].Value = "Active";
            }
            else
            {
                DataGridView1.Rows[n].Cells[3].Value = "Deactive";
            }

Replace

#include <iostream.h>

with

using namespace std;

#include <iostream>

Another approach (especially useful if you need to make a decision to exclude a field at runtime) is to register a TypeAdapter with your gson instance. Example below:

Gson gson = new GsonBuilder()
.registerTypeAdapter(BloodPressurePost.class, new BloodPressurePostSerializer())

In the case below, the server would expect one of two values but since they were both ints then gson would serialize them both. My goal was to omit any value that is zero (or less) from the json that is posted to the server.

public class BloodPressurePostSerializer implements JsonSerializer<BloodPressurePost> {

    @Override
    public JsonElement serialize(BloodPressurePost src, Type typeOfSrc, JsonSerializationContext context) {
        final JsonObject jsonObject = new JsonObject();

        if (src.systolic > 0) {
            jsonObject.addProperty("systolic", src.systolic);
        }

        if (src.diastolic > 0) {
            jsonObject.addProperty("diastolic", src.diastolic);
        }

        jsonObject.addProperty("units", src.units);

        return jsonObject;
    }
}

Try this:

sed -i -e 's/\"//g' file.txt

Found this while Googling. The second post makes a point about the different phases of JSF, which might be causing your error message to become lost. Also, try null in place of "newPassword" because you do not have any object with the id newPassword.

Adding the "x_ua_compatible" tag to the page didn't work for me. Instead I added it as an HTTP Respone Header via IIS and that worked fine.

In IIS Manager select the site then open HTTP Response Headers and click Add:

The site didn't need restarting, but I did need to Ctrl+F5 to force the page to reload.

Here's another way through the GUI that does exactly what your script does even though it goes through Indexes (not Constraints) in the object explorer.

1. Right click on "Indexes" and click "New Index..." (note: this is disabled if you have the table open in design view)

2. Give new index a name ("U_Name"), check "Unique", and click "Add..."

3. Select "Name" column in the next windown

4. Click OK in both windows

The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.

public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
    T returnObject = default(T);
    if (string.IsNullOrEmpty(XmlFilename)) return default(T);

    try
    {
        StreamReader xmlStream = new StreamReader(XmlFilename);
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        returnObject = (T)serializer.Deserialize(xmlStream);
    }
    catch (Exception ex)
    {
        ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
    }
    return returnObject;
}

Then you'd call it like this:

MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);

Had the same problem in my IntelliJ 17 after adding fresh glassfish 4.1.

I had set my JAVA_HOME environment variable as follow:

echo %JAVA_HOME%
C:\Java\jdk1.8.0_121\

Then opened %GLASSFISH_HOME%\glassfish\config\asenv.bat

And just added and the end of the file:

set AS_JAVA=%JAVA_HOME%

Then Glassfish started without problems.

There are two different contexts in Android. One for your application (Let's call it the BIG one) and one for each view (let's call it the activity context).

A linearLayout is a view, so you have to call the activity context. To call it from an activity, simply call "this". So easy isn't it?

When you use

this.getApplicationContext();

You call the BIG context, the one that describes your application and cannot manage your view.

A big problem with Android is that a context cannot call your activity. That's a big deal to avoid this when someone begins with the Android development. You have to find a better way to code your class (or replace "Context context" by "Activity activity" and cast it to "Context" when needed).

Regards.

Just to update my answer. The easiest way to get your Activity context is to define a static instance in your Activity. For example

public class DummyActivity extends Activity
{
    public static DummyActivity instance = null;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Do some operations here
    }

    @Override
    public void onResume()
    {
        super.onResume();
        instance = this;
    }

    @Override
    public void onPause()
    {
        super.onPause();
        instance = null;
    }
}

And then, in your Task, Dialog, View, you could use that kind of code to get your Activity context:

if (DummyActivity.instance != null)
{
    // Do your operations with DummyActivity.instance
}

The following doesn't solve the OP's problem, but the title and error is exactly what I faced.

If your project has a setup.py script in it, you can install that package you are in, with python3 -m pip install -e . or python3 setup.py install or python3 setup.py develop, and this package will be installed, but still editable (so changes to the code will be seen when importing the package). If it doesn't have a setup.py, make sense of it.

Anyway, the problem OP faces seems to not exist anymore?

file one.py:

def function():
    print("output")

file two.py:

#!/usr/bin/env python3

import one
one.function()

chmod +x two.py # To allow execution of the python file
./two.py # Only works if you have a python shebang

Command line output: output

Other solutions seem 'dirty'

In the case of OP with 2 test files, modifying them to work is probably fine. However, in other real scenarios, the methods listed in the other answers is probably not recommended. They require you to modify the python code or restrict your flexibility (running the python file from a specific directory) and generally introduce annoyances. What if you've just cloned a project, and this happens? It probably already works for other people, and making code changes is unnecessary. The chosen answer also wants people to run a script from a specific folder to make it work. This can be a source of long term annoyance, which is never good. It also suggests adding your specific python folder to PATH (can be done through python or command line). Again, what happens if you rename or move the folder in a few months? You have to hunt down this page again, and eventually discover you need to set the path (and that you did exactly this a few months ago), and that you simply need to update a path (sure you could use sys.path and programmatically set it, but this can be flaky still). Many sources of great annoyance.

Could you use online services like this ?

The Safe Area Layout Guide helps avoid underlapping System UI elements when positioning content and controls.

The Safe Area is the area in between System UI elements which are Status Bar, Navigation Bar and Tool Bar or Tab Bar. So when you add a Status bar to your app, the Safe Area shrink. When you add a Navigation Bar to your app, the Safe Area shrinks again.

On the iPhone X, the Safe Area provides additional inset from the top and bottom screen edges in portrait even when no bar is shown. In landscape, the Safe Area is inset from the sides of the screens and the home indicator.

This is taken from Apple's video Designing for iPhone X where they also visualize how different elements affect the Safe Area.

Use a Try Catch block on your server side and in the catch block pass back the exception error to the client. This should give you a helpful error message.

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

For anyone else who did all the advice but the problem still persists.

Check for stored procedure and view DEFINERS. Those definers may no longer exists.

My problem showed up when we changed the wildcard host (%) to IP specific, making the database more secure. Unfortunately there are some views that are still using 'user'@'%' even though 'user'@'172....' is technically correct.

But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:

Javascript Crypto is Hopeless

Matasano's article on this is famous, but the lessons contained therein are pretty important:

https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2011/august/javascript-cryptography-considered-harmful/

To summarize:

• A man-in-the-middle attack can trivially replace your crypto code with <script> function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
• A man-in-the-middle attack is trivial against a page that serves any resource over a non-SSL connection.
• Once you have SSL, you're using real crypto anyways.

And to add a corollary of my own:

• A successful XSS attack can result in an attacker executing code on your client's browser, even if you're using SSL - so even if you've got every hatch battened down, your browser crypto can still fail if your attacker finds a way to execute any javascript code on someone else's browser.

This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!

HTTP Basic Auth

First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.

This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.

The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.

This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!

The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.

HTTP Digest Auth

Is Digest authentication possible with jQuery?

A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.

Query Authentication with Additional Signature Parameters.

Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.

http://tools.ietf.org/html/rfc5849

Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?

JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.

Token

The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.

This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.

SSL Still

The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.

To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.

Token Expiry

It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX". Many of these policies are pretty good ideas.

Firesheeping

However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/

The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.

tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.

A Separate, More Secure Zone

The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?

Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.

Cookie (just means Token)

It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.

Session (still just means Token)

Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:

• Users start with an unauthenticated token.
• The backend maintains a 'state' object that is tied to a user's token.
• The token is provided in a cookie.
• The application environment abstracts the details away from you.

Aside from that, though, it's no different from Token Auth, really.

This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.

OAuth 2.0

OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."

The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."

Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.

There are two ways that OAuth 2.0 can help you:

• Providing Authentication/Information to Others
• Getting Authentication/Information from Others

But when it comes down to it, you're just... using tokens.

Back to your question

So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"

And the answer is: do whatever makes you happy.

The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.

I am 21 so SSL is yes

The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.

I came across a similar need this morning: how to convert a relative path into an absolute path inside a Windows command script.

The following did the trick:

@echo off

set REL_PATH=..\..\
set ABS_PATH=

rem // Save current directory and change to target directory
pushd %REL_PATH%

rem // Save value of CD variable (current directory)
set ABS_PATH=%CD%

rem // Restore original directory
popd

echo Relative path: %REL_PATH%
echo Maps to path: %ABS_PATH%

This is all assuming that the datatype of the column has an implicit conversion for any existing data. I've run into several situations where the existing data, let's say a String can be implicitly converted into the new datatype, let's say Date.

In this situation, it's helpful to know you can create migrations with data conversions. Personally, I like putting these in my model file, and then removing them after all database schemas have been migrated and are stable.

/app/models/table.rb
  ...
  def string_to_date
    update(new_date_field: date_field.to_date)
  end

  def date_to_string
    update(old_date_field: date_field.to_s)
  end
  ...

    def up
        # Add column to store converted data
        add_column :table_name, :new_date_field, :date
        # Update the all resources
        Table.all.each(&:string_to_date)
        # Remove old column
        remove_column :table_name, :date_field
        # Rename new column
        rename_column :table_name, :new_date_field, :date_field
    end

    # Reversed steps does allow for migration rollback
    def down
        add_column :table_name, :old_date_field, :string
        Table.all.each(&:date_to_string)
        remove_column :table_name, :date_field
        rename_column :table_name, :old_date_field, :date_field
    end

    List list1 = new ArrayList();
    list1.add("one");
    list1.add("three");
    list1.add("four");

    List list2 = new ArrayList();
    list2.add("one");
    list2.add("two");
    list2.add("three");
    list2.add("four");
    list2.add("five");


    list2.stream().filter( x -> !list1.contains(x) ).forEach(x -> System.out.println(x));

The output is:

two
five

The issue isn't with the button, the issue is with the div. As divs are block elements, they default to occupying the full width of their parent element (as a general rule; I'm pretty sure there are some exceptions if you're messing around with different positioning schemes in one document that would cause it to occupy the full width of a higher element in the hierarchy).

Anyway, try adding float: left; to the rules for the .button selector. That will cause the div with class button to fit around the button, and would allow you to have multiple floated divs on the same line if you wanted more div.buttons.

Create new instances in your fragments and do like so in your Activity

 private class SlidePagerAdapter extends FragmentStatePagerAdapter {
    public SlidePagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch(position){
            case 0:
                return Fragment1.newInstance();
            case 1:
                return Fragment2.newInstance();
            case 2:
                return Fragment3.newInstance();
            case 3:
                return Fragment4.newInstance();


            default: break;

        }
        return null;
    }

The Best way i Found to do that is this. You can remove my HTML and place yours there.

$('.home-banner-slider').slick({
    dots: false,
    infinite: true,
    autoplay: true,
    autoplaySpeed: 3000,
    speed: 300,
    slidesToScroll: 1,
    arrows: true,
    prevArrow: '<div class="slick-prev"><i class="fa fa-angle-left" aria-hidden="true"></i></div>',
    nextArrow: '<div class="slick-next"><i class="fa fa-angle-right" aria-hidden="true"></i></div>'
});

Just catch the submit event and prevent that, then do ajax

$(document).ready(function () {
    $('#myform').on('submit', function(e) {
        e.preventDefault();
        $.ajax({
            url : $(this).attr('action') || window.location.pathname,
            type: "GET",
            data: $(this).serialize(),
            success: function (data) {
                $("#form_output").html(data);
            },
            error: function (jXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });
});

Where possible, I prefer to call the function rather than dispatch an event. This works well if you have control over the code you want to run, but see below for cases where you don't own the code.

window.onresize = doALoadOfStuff;

function doALoadOfStuff() {
    //do a load of stuff
}

In this example, you can call the doALoadOfStuff function without dispatching an event.

In your modern browsers, you can trigger the event using:

window.dispatchEvent(new Event('resize'));

This doesn't work in Internet Explorer, where you'll have to do the longhand:

var resizeEvent = window.document.createEvent('UIEvents'); 
resizeEvent.initUIEvent('resize', true, false, window, 0); 
window.dispatchEvent(resizeEvent);

jQuery has the trigger method, which works like this:

$(window).trigger('resize');

And has the caveat:

Although .trigger() simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.

You can also simulate events on a specific element...

function simulateClick(id) {
  var event = new MouseEvent('click', {
    'view': window,
    'bubbles': true,
    'cancelable': true
  });

  var elem = document.getElementById(id); 

  return elem.dispatchEvent(event);
}

I set the

variable name : JAVA_HOME value : C:\Program Files\Java\jdk1.6.0_32

I set these properties in system/environment variables without semicolon, tomcat is running on my system.

It really works.

For Django > 3 I do not change settings or anything. I add the below code in the template file.

{{ request.path }}  #  -without GET parameters 
{{ request.get_full_path }}  # - with GET parameters

and in view.py pass request variable to the template file.

view.py:

def view_node_taxon(request, cid):
    showone = get_object_or_404(models.taxon, id = cid)
    context = {'showone':showone,'request':request}
    mytemplate  = loader.get_template('taxon/node.html')
    html = mytemplate.render(context)
    return HttpResponse(html)

If you can't use LIMIT or LIMIT is not an option for your query tool. You can use "ROWNUM" instead, but you will need a sub query:

SELECT FIELD_1, ALIAS1
FROM(SELECT FIELD_1, COUNT(FIELD_1) ALIAS1
    FROM TABLENAME
    GROUP BY FIELD_1
    ORDER BY COUNT(FIELD_1) DESC)
WHERE ROWNUM = 1

Don't give exact heights, but relative ones, adding up to 100%. For example:

  #content {height: 80%;}
  #footer {height: 20%;}

Add in

 html, body {height: 100%;}

For me above solutions didn't work then I tried

map.setCenter(new google.maps.LatLng(lat, lng));

and it worked as expected.

The documentation reiterates your findings here: https://github.com/angular-ui/ui-router/wiki/URL-Routing#stateparams-service

If my memory serves, $stateParams was introduced later than the original $state.params, and seems to be a simple helper injector to avoid continuously writing $state.params.

I doubt there are any best practice guidelines, but context wins out for me. If you simply want access to the params received into the url, then use $stateParams. If you want to know something more complex about the state itself, use $state.

Use the title attribute, for example:

<div title="them's hoverin' words">hover me</div>

or:

<span title="them's hoverin' words">hover me</span>

That's not possible with CSS, you will have to use the Javascript for that. Although you can set the width of the p to as much as 30 characters and next letters will automatically come down but again this won't be that accurate and will vary if the characters are in capital.

Aforementioned answers are great, just putting few points I see might be helpful:

• Func is built-in delegate type

• Func delegate type must return a value. Use Action delegate if no return type needed.

• Func delegate type can have zero to 16 input parameters.

• Func delegate does not allow ref and out parameters.

• Func delegate type can be used with an anonymous method or lambda expression.

  Func<int, int, int> Sum = (x, y) => x + y;

When you need to do it in a string (eg: in your resources) you need to use xml:space="preserve" and the ampersand character codes:

<System:String x:Key="TwoLiner" xml:space="preserve">First line&#10;Second line</System:String>

Or literal newlines in the text:

<System:String x:Key="TwoLiner" xml:space="preserve">First line 
Second line</System:String>

Warning: if you write code like the second example, you have inserted either a newline, or a carriage return and newline, depending on the line endings your operating system and/or text editor use. For instance, if you write that and commit it to git from a linux systems, everything may seem fine -- but if someone clones it to Windows, git will convert your line endings to \r\n and depending on what your string is for ... you might break the world.

Just be aware of that when you're preserving whitespace. If you write something like this:

<System:String x:Key="TwoLiner" xml:space="preserve">
First line 
Second line 
</System:String>

You've actually added four line breaks, possibly four carriage-returns, and potentially trailing white space that's invisible...

height and depth of a tree is equal...

but height and depth of a node is not equal because...

the height is calculated by traversing from the given node to the deepest possible leaf.

depth is calculated from traversal from root to the given node.....

This code is "the least amount of code", but not the best practice:

try
{
    return ObjectA.PropertyA.PropertyB.PropertyC;
}
catch(NullReferenceException)
{
     return null;
}

Ctrl + R - to open the command line and then writes:

I found this article very helpful to understand the difference between them:

RUN - RUN instruction allows you to install your application and packages required for it. It executes any commands on top of the current image and creates a new layer by committing the results. Often you will find multiple RUN instructions in a Dockerfile.

CMD - CMD instruction allows you to set a default command, which will be executed only when you run container without specifying a command. If Docker container runs with a command, the default command will be ignored. If Dockerfile has more than one CMD instruction, all but last
CMD instructions are ignored.

When you create and send a prepared statement to the DBMS, it's stored as the SQL query for execution.

You later bind your data to the query such that the DBMS uses that data as the query parameters for execution (parameterization). The DBMS doesn't use the data you bind as a supplemental to the already compiled SQL query; it's simply the data.

This means it's fundamentally impossible to perform SQL injection using prepared statements. The very nature of prepared statements and their relationship with the DBMS prevents this.

Most of the times it should not be used as the primary key for a table because it really hit the performance of the database. useful links regarding GUID impact on performance and as a primary key.

You've told jQuery to expect a JSONP response, which is why jQuery has added the callback=jQuery16406345664265099913_1319854793396&_=1319854793399 part to the URL (you can see this in your dump of the request).

What you're returning is JSON, not JSONP. Your response looks like

{"red" : "#f00"}

and jQuery is expecting something like this:

jQuery16406345664265099913_1319854793396({"red" : "#f00"})

If you actually need to use JSONP to get around the same origin policy, then the server serving colors.json needs to be able to actually return a JSONP response.

If the same origin policy isn't an issue for your application, then you just need to fix the dataType in your jQuery.ajax call to be json instead of jsonp.

Im not sure this will solve your problem since I dont know where it originats from, but when I import a project i go File -> Import -> Existing projects into workspace. Maybe it will circumvent your problem.

Here is my way.

    <?php

    define('DEBUG',0);

    define('PRODUCTION',1);



    #development_mode : DEBUG / PRODUCTION

    $development_mode = PRODUCTION;



    #Website root path for links

    $app_path = 'http://192.168.0.234/dealer/';



    #User interface files path

    $ui_path = 'ui/';

    #Image gallery path

    $gallery_path = 'ui/gallery/';


    $mysqlserver = "localhost";
    $mysqluser = "root";
    $mysqlpass = "";
    $mysqldb = "dealer_plus";

   ?>

Any doubts please comment

If all that's needed is to send html code inline in the code, we can use below

var app = express();
app.get('/test.html', function (req, res) {
   res.header('Content-Type', 'text/html').send("<html>my html code</html>");
});

I am using below code for today and database date.

TIMESTAMPDIFF(MINUTE,T.runTime,NOW()) > 20

According to the documentation, the first argument can be any of the following:

MICROSECOND
SECOND
MINUTE
HOUR
DAY
WEEK
MONTH
QUARTER
YEAR

You can use Expressions windows: while debugging, menu window -> Show View -> Expressions, then it has place to type variables of which you need to see contents

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

Either make ActiveAlarm implement Comparable<ActiveAlarm> or implement Comparator<ActiveAlarm> in a separate class. Then call:

Collections.sort(list);

or

Collections.sort(list, comparator);

In general, it's a good idea to implement Comparable<T> if there's a single "natural" sort order... otherwise (if you happen to want to sort in a particular order, but might equally easily want a different one) it's better to implement Comparator<T>. This particular situation could go either way, to be honest... but I'd probably stick with the more flexible Comparator<T> option.

EDIT: Sample implementation:

public class AlarmByTimesComparer implements Comparator<ActiveAlarm> {
  @Override
  public int compare(ActiveAlarm x, ActiveAlarm y) {
    // TODO: Handle null x or y values
    int startComparison = compare(x.timeStarted, y.timeStarted);
    return startComparison != 0 ? startComparison
                                : compare(x.timeEnded, y.timeEnded);
  }

  // I don't know why this isn't in Long...
  private static int compare(long a, long b) {
    return a < b ? -1
         : a > b ? 1
         : 0;
  }
}

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

Why not try to add a ScrollView to wrap whatever it is you want to scroll. Here is how I have done it, where I actually leave a header on top which does not scroll, while the dialog widgets (in particular the EditTexts) scroll when you open soft keypad.

<LinearLayout android:id="@+id/HeaderLayout" >
  <!-- Here add a header or whatever will not be scrolled. -->
</LinearLayout>
<ScrollView android:id="@+id/MainForm" >
  <!-- Here add your edittexts or whatever will scroll. -->
</ScrollView>

I would typically have a LinearLayout inside the ScrollView, but that is up to you. Also, setting Scrollbar style to outsideInset helps, at least on my devices.

String int2string = Integer.toHexString(INTEGERColor); //to ARGB
String HtmlColor = "#"+ int2string.substring(int2string.length() - 6, int2string.length()); // a stupid way to append your color

You may just remove all spaces and leverage LINQ All:

Determines whether all elements of a sequence satisfy a condition.

Use it as shown below:

Dim number As String = "077 234 211"
If number.Replace(" ", "").All(AddressOf Char.IsDigit) Then
    Console.WriteLine("The string is all numeric (spaces ignored)!")
Else
    Console.WriteLine("The string contains a char that is not numeric and space!")
End If

To only check if a string consists of only digits use:

If number.All(AddressOf Char.IsDigit) Then

I came across the same issue when dealing with a non-trivial view (there are nested scopes). And finally discovered this is a known tricky thing when developing AngularJS application due to the nature of prototype-based inheritance of java-script. AngularJS nested scopes are created through this mechanism. And value created from ng-model is placed in children scope, not saying parent scope (maybe the one injected into controller) won't see the value, the value will also shadow any property with same name defined in parent scope if not use dot to enforce a prototype reference access. For more details, checkout the online video specific to illustrate this issue, http://egghead.io/video/angularjs-the-dot/ and comments following up it.

To go up a directory in a link, use ... This means "go up one directory", so your link will look something like this:

<a href="../index.html">Home</a>

It depends on your application and its use as to the level of security you need.

In terms of security, you should be validating all values you get from the querystring or post parameters, to ensure they're valid.

You may also wish to add logging for others, including analysis of weblogs so you can determine if an attempt to hack your system is occuring.

I don't believe it's possible to inject javascript into a URL and have this run, unless your application is using parameters without validating them first.

Setting a width of 100% is the full width of the div it's in, not the original full-sized image. There is no way to do that without JavaScript or some other scripting language that can measure the image. If you can have a fixed width or fixed height of the div (like 200px wide) then it shouldn't be too hard to give the image a range to fill. But if you put a 20x20 pixel image in a 200x300 pixel box it will still be distorted.

Postman in the chrome store is simple but powerful.

Also, if all you are trying to do is break up the main.go file into multiple files, then just name the other files "package main" as long as you only define the main function in one of those files, you are good to go.

Make an exception handler like this,

private int ConvertIntoNumeric(String xVal)
{
 try
  { 
     return Integer.parseInt(xVal);
  }
 catch(Exception ex) 
  {
     return 0;

as per requested, here is the comment I gave earlier:

have a look at this:

• Vim integration to MonoDevelop for .net stuff at least..
• OmniCompletion

this link should help you if you want to use monodevelop on a MacOSX

Good luck and happy coding.

There is no real limit -- everything is named with a 160-bit name. The size of the file must be representable in a 64 bit number so no real limit there either.

There is a practical limit, though. I have a repository that's ~8GB with >880,000 files and git gc takes a while. The working tree is rather large so operations that inspect the entire working directory take quite a while. This repo is only used for data storage, though, so it's just a bunch of automated tools that handle it. Pulling changes from the repo is much, much faster than rsyncing the same data.

some keywords:

• Maven 3
• BOM (DependencyManagement of own dependencies)
• Parent for all Projects (DependencyManagement from external dependencies and PluginManagement for global Project configuration)
• JUnit / Mockito / DBUnit
• Clean War project without WEB-INF/lib because dependencies are in EAR/lib folder.
• Clean Ear project.
• Minimal deployment descriptors for Java EE7
• No Local EJB Interface because @LocalBean is sufficient.
• Minimal maven configuration through maven user properties
• Actual Deployment Descriptors for Servlet 3.1 / EJB 3.2 / JPA 2.1
• usage of macker-maven-plugin to check architecture rules
• Integration Tests enabled, but skipped. (skipITs=false) useful to enable on CI Build Server

map.keySet()

will return you all the keys. If you want the keys to be sorted, you might consider a TreeMap

Another approach, if you simply wish to print a PDF file programmatically, is to use the LPR command: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/lpr.mspx?mfr=true

LPR is available on newer versions of Windows too (e.g. Vista/7), but you need to enable it in the Optional Windows Components.

For example:

Process.Start("LPR -S printerdnsalias -P raw C:\files\file.pdf");

You can also use the printer IP address instead of the alias.

This assumes that your printer supports PDF Direct Printing otherwise this will only work for PostScript and ASCII files. Also, the printer needs to have a network interface installed and you need to know it's IP address or alias.

Here is how to run a elevated powershell command and collect its output form within a windows batch file in a single command(i.e not writing a ps1 powershell script).

powershell -Command 'Start-Process powershell -ArgumentList "-Command (Get-Process postgres | Select-Object Path | Select-Object -Index 0).Path | Out-File -encoding ASCII $env:TEMP\camp-postgres.tmp" -Verb RunAs'

Above you see i first launch a powershell with elevated prompt and then ask that to launch another powershell(sub shell) to run the command.

ionic info

This will give you the ionic version,node, npm and os.

If you need only ionic version use ionic -v.

If your project's development ionic version and your global versions are different then check them by using the below commands.

To check the globally installed ionic version ionic -g and to check the project's ionic version use ionic -g.

To check the project's ionic version use ionic -v in your project path or else ionic info to get the details of ionic and its dependencies.

I know it is always preferred not to hardcode the sudo password in the script. However, for some reason, if you have no permission to modify /etc/sudoers or change file owner, Pexpect is a feasible alternative.

Here is a Python function sudo_exec for your reference:

import platform, os, logging
import subprocess, pexpect

log = logging.getLogger(__name__)

def sudo_exec(cmdline, passwd):
    osname = platform.system()
    if osname == 'Linux':
        prompt = r'\[sudo\] password for %s: ' % os.environ['USER']
    elif osname == 'Darwin':
        prompt = 'Password:'
    else:
        assert False, osname

    child = pexpect.spawn(cmdline)
    idx = child.expect([prompt, pexpect.EOF], 3)
    if idx == 0: # if prompted for the sudo password
        log.debug('sudo password was asked.')
        child.sendline(passwd)
        child.expect(pexpect.EOF)
return child.before

    // Disable #x
    $( "#x" ).prop( "disabled", true );
    // Enable #x
    $( "#x" ).prop( "disabled", false );

Sometimes you need to disable/enable the form element like input or textarea. Jquery helps you to easily make this with setting disabled attribute to "disabled". For e.g.:

  //To disable 
  $('.someElement').attr('disabled', 'disabled');

To enable disabled element you need to remove "disabled" attribute from this element or empty it's string. For e.g:

//To enable 
$('.someElement').removeAttr('disabled');

// OR you can set attr to "" 
$('.someElement').attr('disabled', '');

It's a bit late but I came across this post.

It's not perfect but here's what I do.

HTML Code

<div class="showcase-menu-social"><img class="margin-left-20" src="images/graphics/facebook-50x50.png" alt="facebook-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/twitter-50x50.png" alt="twitter-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/youtube-50x50.png" alt="youtube-50x50" width="50" height="50" /></div>

CSS Code

.showcase-menu {
  margin-left:20px;
    margin-right:20px;
    padding: 0px 20px 0px 20px;
    background-color: #C37500;
    behavior: url(/css/border-radius.htc);
  border-radius: 20px;
    }

.showcase-menu-social img:hover {
  background-color: #C37500;
  opacity:0.7 !important;
  filter:alpha(opacity=70) !important; /* For IE8 and earlier */
  box-shadow: 0 0 0px #000000 !important;
}

Now my border radius of 20px matches up exactly with the image border radius. As you can see the .showcase-menu has the same background as the .showcase-menu-social. What this does is to allow the 'opacity' to take effect and no 'square' background or border shows, thus the image slightly reduces it's saturation on hover.

It's a nice effect and does give the viewer the feedback that the image is in focus. I'm fairly sure on a darker background, it would have even a better effect.

The nice thing is that this is valid HTML-CSS code and will validate. To be honest, it should work on non-image elements just as good as images.

Enjoy!

NON JQUERY since there were a bunch of links using elem.style.height in the top of these answers...

INNER HEIGHT:
https://developer.mozilla.org/en-US/docs/Web/API/Element.clientHeight

document.getElementById(id_attribute_value).clientHeight;

OUTER HEIGHT:
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement.offsetHeight

document.getElementById(id_attribute_value).offsetHeight; 

Or one of my favorite references: http://youmightnotneedjquery.com/

How about just doing it locally? Most likely you are able to download from https source through your browser

1. Download your module file (mysql-connector-python-2.0.3.zip /gz... etc).

2. Extract it and go the extracted dir where setup.py is located and call:

   C:\mysql-connector-python-2.0.3>python.exe setup.py install
   

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

You can use System.IO.Path.GetFileName to do this.

E.g.,

string[] files = Directory.GetFiles(dir);
foreach(string file in files)
    Console.WriteLine(Path.GetFileName(file));

While you could use FileInfo, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles unless you need the additional functionality of the FileInfo class.

Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.

php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.

An example

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}

modify your bash profile as follows <>$vim ~/.bash_profile export PATH=/usr/local/mysql/bin:$PATH Once its saved you can type in mysql to bring mysql prompt in your terminal.

For people coming here from Google looking for a fast way to downsample images in numpy arrays for use in Machine Learning applications, here's a super fast method (adapted from here ). This method only works when the input dimensions are a multiple of the output dimensions.

The following examples downsample from 128x128 to 64x64 (this can be easily changed).

Channels last ordering

# large image is shape (128, 128, 3)
# small image is shape (64, 64, 3)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((output_size, bin_size, 
                                   output_size, bin_size, 3)).max(3).max(1)

Channels first ordering

# large image is shape (3, 128, 128)
# small image is shape (3, 64, 64)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((3, output_size, bin_size, 
                                      output_size, bin_size)).max(4).max(2)

For grayscale images just change the 3 to a 1 like this:

Channels first ordering

# large image is shape (1, 128, 128)
# small image is shape (1, 64, 64)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((1, output_size, bin_size,
                                      output_size, bin_size)).max(4).max(2)

This method uses the equivalent of max pooling. It's the fastest way to do this that I've found.

Change your subplot settings to:

plt.subplot(1, 2, 1)

...

plt.subplot(1, 2, 2)

The parameters for subplot are: number of rows, number of columns, and which subplot you're currently on. So 1, 2, 1 means "a 1-row, 2-column figure: go to the first subplot." Then 1, 2, 2 means "a 1-row, 2-column figure: go to the second subplot."

You currently are asking for a 2-row, 1-column (that is, one atop the other) layout. You need to ask for a 1-row, 2-column layout instead. When you do, the result will be:

In order to minimize the overlap of subplots, you might want to kick in a:

plt.tight_layout()

before the show. Yielding:

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

If you want to calculate the zscore for all of the columns, you can just use the following:

df_zscore = (df - df.mean())/df.std()

Is there something special with that directory or are you really just asking how to copy directories?

Copy recursively via CLI:

cp -R <sourcedir> <destdir>

If you're only seeing the files under the sourcedir being copied (instead of sourcedir as well), that's happening because you kept the trailing slash for sourcedir:

cp -R <sourcedir>/ <destdir>

The above only copies the files and their directories inside of sourcedir. Typically, you want to include the directory you're copying, so drop the trailing slash:

cp -R <sourcedir> <destdir>

I discovered an error in my first post, so I decided to sit down and do the the math. What I found is that the number system used to identify Excel columns is not a base 26 system, as another person posted. Consider the following in base 10. You can also do this with the letters of the alphabet.

Space:.........................S1, S2, S3 : S1, S2, S3
....................................0, 00, 000 :.. A, AA, AAA
....................................1, 01, 001 :.. B, AB, AAB
.................................... …, …, … :.. …, …, …
....................................9, 99, 999 :.. Z, ZZ, ZZZ
Total states in space: 10, 100, 1000 : 26, 676, 17576
Total States:...............1110................18278

Excel numbers columns in the individual alphabetical spaces using base 26. You can see that in general, the state space progression is a, a^2, a^3, … for some base a, and the total number of states is a + a^2 + a^3 + … .

Suppose you want to find the total number of states A in the first N spaces. The formula for doing so is A = (a)(a^N - 1 )/(a-1). This is important because we need to find the space N that corresponds to our index K. If I want to find out where K lies in the number system I need to replace A with K and solve for N. The solution is N = log{base a} (A (a-1)/a +1). If I use the example of a = 10 and K = 192, I know that N = 2.23804… . This tells me that K lies at the beginning of the third space since it is a little greater than two.

The next step is to find exactly how far in the current space we are. To find this, subtract from K the A generated using the floor of N. In this example, the floor of N is two. So, A = (10)(10^2 – 1)/(10-1) = 110, as is expected when you combine the states of the first two spaces. This needs to be subtracted from K because these first 110 states would have already been accounted for in the first two spaces. This leaves us with 82 states. So, in this number system, the representation of 192 in base 10 is 082.

The C# code using a base index of zero is

    private string ExcelColumnIndexToName(int Index)
    {
        string range = string.Empty;
        if (Index < 0 ) return range;
        int a = 26;
        int x = (int)Math.Floor(Math.Log((Index) * (a - 1) / a + 1, a));
        Index -= (int)(Math.Pow(a, x) - 1) * a / (a - 1);
        for (int i = x+1; Index + i > 0; i--)
        {
            range = ((char)(65 + Index % a)).ToString() + range;
            Index /= a;
        }
        return range;
    }

//Old Post

A zero-based solution in C#.

    private string ExcelColumnIndexToName(int Index)
    {
        string range = "";
        if (Index < 0 ) return range;
        for(int i=1;Index + i > 0;i=0)
        {
            range = ((char)(65 + Index % 26)).ToString() + range;
            Index /= 26;
        }
        if (range.Length > 1) range = ((char)((int)range[0] - 1)).ToString() + range.Substring(1);
        return range;
    }

As long as you have the website created on the shared, VPS or Dedicated, you should be able to always use the following in your host file, which is what your browser will use.

67.225.235.59 somerandomservice.com www.somerandomservice.com

this may help you.

In .cs page,

//Declare a string
   public string usertypeurl = "";
  //check who is the user
       //place your code to check who is the user
       //if it is admin
       usertypeurl = "help/AdminTutorial.html";
       //if it is other 
        usertypeurl = "help/UserTutorial.html";

In .aspx age pass this variabe

  <a href='<%=usertypeurl%>'>Tutorial</a>

The reason is that C++ objects are constructed like onions, from the inside out. Base classes are constructed before derived classes. So, before a B can be made, an A must be made. When A's constructor is called, it's not a B yet, so the virtual function table still has the entry for A's copy of fn().

$('#div_id').css({marginTop: '-=15px'});

This will alter the css for the element with the id "div_id"

To get the effect you want I recommend adding the code above to a callback function in your animation (that way the div will be moved up after the animation is complete):

$('#div_id').animate({...}, function () {
    $('#div_id').css({marginTop: '-=15px'});
});

And of course you could animate the change in margin like so:

$('#div_id').animate({marginTop: '-=15px'});

Here are the docs for .css() in jQuery: http://api.jquery.com/css/

And here are the docs for .animate() in jQuery: http://api.jquery.com/animate/

To simulate a click on an anchor while landing on a page, I just used jQuery to animate the scrollTop property in $(document).ready. No need for a complex trigger, and that works on IE 6 and every other browser.

My Newbie way ;-) Please let me know if that's correct. It seems to be working for all my cases:

#define IPT_SIZE 5

int findNULL(char* arr)
{
    for (int i = 0; i < strlen(arr); i++)
    {
        if (*(arr+i) == '\n')
        {
            return i;
        }
    }
    return 0;
}

int main()
{
    char *input = malloc(IPT_SIZE + 1 * sizeof(char)), buff;
    int counter = 0;

    //prompt user for the input:
    printf("input string no longer than %i characters: ", IPT_SIZE);
    do
    {
        fgets(input, 1000, stdin);
        *(input + findNULL(input)) = '\0';
        if (strlen(input) > IPT_SIZE)
        {
            printf("error! the given string is too large. try again...\n");
            counter++;
        }
        //if the counter exceeds 3, exit the program (custom function):
        errorMsgExit(counter, 3); 
    }
    while (strlen(input) > IPT_SIZE);

//rest of the program follows

free(input)
return 0;
}

for example:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="42dp"  
  android:maxHeight="42dp"  
  android:scaleType="fitCenter"  
  android:layout_marginLeft="3dp"  
  android:src="@drawable/icon"  
  /> 

Add property android:scaleType="fitCenter" and android:adjustViewBounds="true".

I'm lately here. But somethings I just known that might help you a bit.

If you are using Java, there is nothing much to change. But for kotlin developers, here is some following snippet I think that can make you a basement to run on:

• Parent fragment:

inline fun <reified T : SampleFragment> newInstance(text: String): T {
    return T::class.java.newInstance().apply {
        arguments = Bundle().also { it.putString("key_text_arg", text) }
    }
}

• Normal call

val f: SampleFragment = SampleFragment.newInstance("ABC")
// or val f = SampleFragment.newInstance<SampleFragment>("ABC")

• You can extend the parent init operation in child fragment class by:

fun newInstance(): ChildSampleFragment {
    val child = UserProfileFragment.newInstance<ChildSampleFragment>("XYZ")
    // Do anything with the current initialized args bundle here
    // with child.arguments = ....
    return child
}

Happy coding.

You want:

if (document.getElementById('customx').value === ""){
    //do something
}

The value property will give you a string value and you need to compare that against an empty string.

appsettings.json:

"MySetting": {
  "MyValues": [
    "C#",
    "ASP.NET",
    "SQL"
  ]
},

MySetting class:

namespace AspNetCore.API.Models
{
    public class MySetting : IMySetting
    {
        public string[] MyValues { get; set; }
    }

    public interface IMySetting
    {
        string[] MyValues { get; set; }
    }
}

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    ...
    services.Configure<MySetting>(Configuration.GetSection(nameof(MySetting)));
    services.AddSingleton<IMySetting>(sp => sp.GetRequiredService<IOptions<MySetting>>().Value);
    ...
}

Controller.cs

public class DynamicController : ControllerBase
{
    private readonly IMySetting _mySetting;

    public DynamicController(IMySetting mySetting)
    {
        this._mySetting = mySetting;
    }
}

Access values:

var myValues = this._mySetting.MyValues;

On my Windows 10 Enterprise, gulp was not installed in %AppData%, which is C:\Users\username\AppData\npm\node_modules on my machine, but in C:\Users\username\AppData\Local\npm\node_modules.

To get gulp to be picked up at the command prompt or in powershell, I added to the user PATH the value C:\Users\username\AppData\Local\npm. After that it worked like a charm. Naturally I had to close the command prompt or powershell window and re-open for the above to take effect.

This method automatically outputs column names with your row data using BCP.

The script writes one file for the column headers (read from INFORMATION_SCHEMA.COLUMNS table) then appends another file with the table data.

The final output is combined into TableData.csv which has the headers and row data. Just replace the environment variables at the top to specify the Server, Database and Table name.

set BCP_EXPORT_SERVER=put_my_server_name_here
set BCP_EXPORT_DB=put_my_db_name_here
set BCP_EXPORT_TABLE=put_my_table_name_here

BCP "DECLARE @colnames VARCHAR(max);SELECT @colnames = COALESCE(@colnames + ',', '') + column_name from %BCP_EXPORT_DB%.INFORMATION_SCHEMA.COLUMNS where TABLE_NAME='%BCP_EXPORT_TABLE%'; select @colnames;" queryout HeadersOnly.csv -c -T -S%BCP_EXPORT_SERVER%

BCP %BCP_EXPORT_DB%.dbo.%BCP_EXPORT_TABLE% out TableDataWithoutHeaders.csv -c -t, -T -S%BCP_EXPORT_SERVER%

set BCP_EXPORT_SERVER=
set BCP_EXPORT_DB=
set BCP_EXPORT_TABLE=

copy /b HeadersOnly.csv+TableDataWithoutHeaders.csv TableData.csv

del HeadersOnly.csv
del TableDataWithoutHeaders.csv

Note that if you need to supply credentials, replace the -T option with -U my_username -P my_password

This method has the advantage of always having the column names in sync with the table by using INFORMATION_SCHEMA.COLUMNS. The downside is that it creates temporary files. Microsoft should really fix the bcp utility to support this.

This solution uses the SQL row concatenation trick from here combined with bcp ideas from here

It might be easier for you to understand using Functionoids which are expressively neater and more powerful to use, see this excellent and highly recommended C++ FAQ lite, in particular, look at section 33.12 onwards, but nonetheless, read it from the start of that section to gain a grasp and understanding of it.

To answer your question:

typedef void (*foobar)() fubarfn;

void Fun(fubarfn& baz){
   fubarfn = baz;
   baz();
}

Edit:

• & means the reference address
• * means the value of what's contained at the reference address, called de-referencing

So using the reference, example below, shows that we are passing in a parameter, and directly modify it.

void FunByRef(int& iPtr){
    iPtr = 2;
}

int main(void){
    // ...
    int n;
    FunByRef(n);
    cout << n << endl; // n will have value of 2
}

I am sharing our nodejs implementation of the solution as implemented by @Raymond Hettinger.

var crypto = require('crypto');
var s = 'she sells sea shells by the sea shore';
console.log(BigInt('0x' + crypto.createHash('sha1').update(s).digest('hex'))%(10n ** 8n));

WebApiConfig.Register(GlobalConfiguration.Configuration); should be on top.

If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.

But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.

The following worked for me after hours of trying

      $http.post("http://localhost:8080/yourresource", parameter, {headers:

However following code did not work, I am unclear as to why, hopefully someone can improve this answer.

                              'Access-Control-Allow-Methods': 'POST'} 
                })

Did you include a reference to System.Web.Extensions? If you click on your first link it says which assembly it's in.

This is a solution in shell script:

apk="$apk_path"

1. Install apk

adb install "$apk"
sleep 1

2. Get package name

pkg_info=`aapt dump badging "$apk" | head -1 | awk -F " " '{print $2}'`
eval $pkg_info > /dev/null

3. Start app

pkg_name=$name
adb shell monkey -p "${pkg_name}" -c android.intent.category.LAUNCHER 1

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

You could keep it simple and use the native color translator:

Color red = ColorTranslator.FromHtml("#FF0000");
string redHex = ColorTranslator.ToHtml(red);

Then break the three color pairs into integer form:

int value = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

You can do something like that in ES6.

new Array(10).fill().map((e,i) => {
   return {idx: i}
});

To clone a git repo into an empty existing directory do the following:

cd myfolder
git clone https://myrepo.com/git.git . 

Notice the . at the end of your git clone command. That will download the repo into the current working directory.

android:inputMethod

is deprecated, instead use inputType :

 android:inputType="numberPassword"

You can use a Python script with scp and os library to make a system call.

1. ssh-keygen -t rsa -b 2048 (local machine)
2. ssh-copy-id user@remote_server_address
3. create a Python script like:

    import os
    cmd = 'scp user@remote_server_address:remote_file_path local_file_path'
    os.system(cmd)

4. create a rule in crontab to automate your script
5. done

This gives me the most reliable results:

Sub RangeToPicture()
  Dim FileName As String: FileName = "C:\file.bmp"
  Dim rPrt As Range: Set rPrt = ThisWorkbook.Sheets("Sheet1").Range("A1:C6")

  Dim chtObj As ChartObject
  rPrt.CopyPicture xlScreen, xlBitmap
  Set chtObj = ActiveSheet.ChartObjects.Add(1, 1, rPrt.Width, rPrt.Height)
  chtObj.Activate
  ActiveChart.Paste
  ActiveChart.Export FileName
  chtObj.Delete
End Sub

I just came up with a general solution, which should work on most websites. I tried this on Chrome only, but this method should work with any other browser, though, as Dev Tools are pretty much the same in them all.

Steps:

1. Open the browser's Dev Tools (usually F12, or Ctrl-Shift-I, or right-click and then Inspect in the popup menu) on the page with the video you are interested in.
2. Go to Network tab and then reload the page. The tab will get populated with a list of requests (may be up to a hundred of them or even more).
3. Search through the names of requests and find the request with .m3u8 extension. There may be many of them, but most likely the first you find is the one you are looking for. It may have any name, e.g. playlist.m3u8.
4. Open the request and under Headers subsection you will see request's full URL in Request URL field. Copy it.
5. Extract the video from m3u8. There are many ways to do it, I'll give you those I tried, but you can google more by "download video from m3u8".
   • Option 1. If you have VLC player installed, feed the URL to VLC using "Open Network Stream..." menu option. I'm not going to go into details on this part here, there are a number of comprehensive guides in many places, for example, here. If the page doesn't work, you can always google another one by "vlc download online video".
   • Option 2. If you are more into command line, use FFMPEG or your own script, as directed in this SuperUser question.

(I posted earlier, and @Marc Gravell has corrected me)

Here's a demonstration of the difference:

static void Main(string[] args) {
    try {
        ThrowException1(); // line 19
    } catch (Exception x) {
        Console.WriteLine("Exception 1:");
        Console.WriteLine(x.StackTrace);
    }
    try {
        ThrowException2(); // line 25
    } catch (Exception x) {
        Console.WriteLine("Exception 2:");
        Console.WriteLine(x.StackTrace);
    }
}

private static void ThrowException1() {
    try {
        DivByZero(); // line 34
    } catch {
        throw; // line 36
    }
}
private static void ThrowException2() {
    try {
        DivByZero(); // line 41
    } catch (Exception ex) {
        throw ex; // line 43
    }
}

private static void DivByZero() {
    int x = 0;
    int y = 1 / x; // line 49
}

and here is the output:

Exception 1:
   at UnitTester.Program.DivByZero() in <snip>\Dev\UnitTester\Program.cs:line 49
   at UnitTester.Program.ThrowException1() in <snip>\Dev\UnitTester\Program.cs:line 36
   at UnitTester.Program.TestExceptions() in <snip>\Dev\UnitTester\Program.cs:line 19

Exception 2:
   at UnitTester.Program.ThrowException2() in <snip>\Dev\UnitTester\Program.cs:line 43
   at UnitTester.Program.TestExceptions() in <snip>\Dev\UnitTester\Program.cs:line 25

You can see that in Exception 1, the stack trace goes back to the DivByZero() method, whereas in Exception 2 it does not.

Take note, though, that the line number shown in ThrowException1() and ThrowException2() is the line number of the throw statement, not the line number of the call to DivByZero(), which probably makes sense now that I think about it a bit...

Output in Release mode

Exception 1:

at ConsoleAppBasics.Program.ThrowException1()
at ConsoleAppBasics.Program.Main(String[] args)

Exception 2:

at ConsoleAppBasics.Program.ThrowException2()
at ConsoleAppBasics.Program.Main(String[] args)

Is it maintains the original stackTrace in debug mode only?

First all answers are right, you can pass the data except custom objects by using Intent. If you want to pass the custom objects, you have to implement Serialazable or Parcelable to your custom object class. I thought it's too much complicated...

So if your project is simple, try to use DataCache. That provides super simple way for passing data. Ref: Github project CachePot

1- Set this to View or Activity or Fragment which will send data

DataCache.getInstance().push(obj);

2- Get data anywhere like below

public class MainFragment extends Fragment
{
    private YourObject obj;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        obj = DataCache.getInstance().pop(YourObject.class);

    }//end onCreate()
}//end class MainFragment

If you are looking for a difference expressed as a combination of years, months, and days, I would suggest this function:

function interval(date1, date2) {_x000D_
    if (date1 > date2) { // swap_x000D_
        var result = interval(date2, date1);_x000D_
        result.years  = -result.years;_x000D_
        result.months = -result.months;_x000D_
        result.days   = -result.days;_x000D_
        result.hours  = -result.hours;_x000D_
        return result;_x000D_
    }_x000D_
    result = {_x000D_
        years:  date2.getYear()  - date1.getYear(),_x000D_
        months: date2.getMonth() - date1.getMonth(),_x000D_
        days:   date2.getDate()  - date1.getDate(),_x000D_
        hours:  date2.getHours() - date1.getHours()_x000D_
    };_x000D_
    if (result.hours < 0) {_x000D_
        result.days--;_x000D_
        result.hours += 24;_x000D_
    }_x000D_
    if (result.days < 0) {_x000D_
        result.months--;_x000D_
        // days = days left in date1's month, _x000D_
        //   plus days that have passed in date2's month_x000D_
        var copy1 = new Date(date1.getTime());_x000D_
        copy1.setDate(32);_x000D_
        result.days = 32-date1.getDate()-copy1.getDate()+date2.getDate();_x000D_
    }_x000D_
    if (result.months < 0) {_x000D_
        result.years--;_x000D_
        result.months+=12;_x000D_
    }_x000D_
    return result;_x000D_
}_x000D_
_x000D_
// Be aware that the month argument is zero-based (January = 0)_x000D_
var date1 = new Date(2015, 4-1, 6);_x000D_
var date2 = new Date(2015, 5-1, 9);_x000D_
_x000D_
document.write(JSON.stringify(interval(date1, date2)));

This solution will treat leap years (29 February) and month length differences in a way we would naturally do (I think).

So for example, the interval between 28 February 2015 and 28 March 2015 will be considered exactly one month, not 28 days. If both those days are in 2016, the difference will still be exactly one month, not 29 days.

Dates with exactly the same month and day, but different year, will always have a difference of an exact number of years. So the difference between 2015-03-01 and 2016-03-01 will be exactly 1 year, not 1 year and 1 day (because of counting 365 days as 1 year).

I achieved the goal where I have multiple images to insert in the DB as

INSERT INTO [dbo].[User]
           ([Name]
           ,[Image1]
           ,[Age]
           ,[Image2]
           ,[GroupId]
           ,[GroupName])
           VALUES
           ('Umar'
           , (SELECT BulkColumn 
            FROM Openrowset( Bulk 'path-to-file.jpg', Single_Blob) as Image1)
           ,26
           ,(SELECT BulkColumn 
            FROM Openrowset( Bulk 'path-to-file.jpg', Single_Blob) as Image2)
            ,'Group123'
           ,'GroupABC')

ANDROID_HOME

Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead.

ANDROID_SDK_ROOT

Installation directory of Android SDK package.

Example: C:\AndroidSDK or /usr/local/android-sdk/

ANDROID_NDK_ROOT

Installation directory of Android NDK package. (WITHOUT ANY SPACE)

Example: C:\AndroidNDK or /usr/local/android-ndk/

ANDROID_SDK_HOME

Location of SDK related data/user files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_EMULATOR_HOME

Location of emulator-specific data files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_AVD_HOME

Location of AVD-specific data files.

Example: C:\Users\<USERNAME>\.android\avd\ or ~/.android/avd/

JDK_HOME and JAVA_HOME

Installation directory of JDK (aka Java SDK) package.

Note: This is used to run Android Studio(and other Java-based applications). Actually when you run Android Studio, it checks for JDK_HOME then JAVA_HOME environment variables to use.
