If you are trying to clear out a receive buffer for something that receives strings I have found the best way is to use memset as described above. The reason is that no matter how big the next received string is (limited to sizeof buffer of course), it will automatically be an asciiz string if written into a buffer that has been pre-zeroed.

I wouldn't use function from one controller into another. A better approach would be to move the common function to a service and then inject the service in both controllers.

Interfaces can not be directly instantiated, you should instantiate classes that implements such Interfaces.

Try this:

NameValuePair[] params = new BasicNameValuePair[] {
        new BasicNameValuePair("param1", param1),
        new BasicNameValuePair("param2", param2),
};

You need to set both the user-agent and the referer:

 wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" --referrer  connect.wso2.com http://dist.wso2.org/products/carbon/4.2.0/wso2carbon-4.2.0.zip

OK, here are the things that come into mind:

• Your WCF service presumably running on IIS must be running under the security context that has the privilege that calls the Web Service. You need to make sure in the app pool with a user that is a domain user - ideally a dedicated user.
• You can not use impersonation to use user's security token to pass back to ASMX using impersonation since my WCF web service calls another ASMX web service, installed on a **different** web server
• Try changing Ntlm to Windows and test again.

OK, a few words on impersonation. Basically it is a known issue that you cannot use the impersonation tokens that you got to one server, to pass to another server. The reason seems to be that the token is a kind of a hash using user's password and valid for the machine generated from so it cannot be used from the middle server.

UPDATE

Delegation is possible under WCF (i.e. forwarding impersonation from a server to another server). Look at this topic here.

I agree with bizl

[XmlInclude(typeof(ParentOfTheItem))]
[Serializable]
public abstract class WarningsType{ }

also if you need to apply this included class to an object item you can do like that

[System.Xml.Serialization.XmlElementAttribute("Warnings", typeof(WarningsType))]
public object[] Items
{
    get
    {
        return this.itemsField;
    }
    set
    {
        this.itemsField = value;
    }
}

I like the bytes.Buffer struct. I see it has ReadFrom and String methods. I've used it with a []byte but not an io.Reader.

I had this same problem and resolved it by making sure all references to the previous version of crystal from the Web Config file, the server, and the publishing workstation were removed. Other than the full trust basically everything that user707217 did, I did and it worked for my upgraded Web application

I find gpustat very useful. In can be installed with pip install gpustat, and prints breakdown of usage by processes or users.

I wrote a simple node script for deleting messages from public/private channels and chats. You can modify and use it.

https://gist.github.com/firatkucuk/ee898bc919021da621689f5e47e7abac

First, modify your token in the scripts configuration section then run the script:

node ./delete-slack-messages CHANNEL_ID

Get an OAuth token:

1. Go to https://api.slack.com/apps
2. Click 'Create New App', and name your (temporary) app.
3. In the side nav, go to 'Oauth & Permissions'
4. On that page, find the 'Scopes' section. Click 'Add an OAuth Scope' and add 'channels:history' and 'chat:write'. (see scopes)
5. At the top of the page, Click 'Install App to Workspace'. Confirm, and on page reload, copy the OAuth Access Token.

Find the channel ID

Also, the channel ID can be seen in the browser URL when you open slack in the browser. e.g.

https://mycompany.slack.com/messages/MY_CHANNEL_ID/

or

https://app.slack.com/client/WORKSPACE_ID/MY_CHANNEL_ID

If you would like to query all columns

List<Users> list_users = new List<Users>();
MySqlConnection cn = new MySqlConnection("connection");
MySqlCommand cm = new MySqlCommand("select * from users",cn);
try
{
    cn.Open();
    MySqlDataReader dr = cm.ExecuteReader();
    while (dr.Read())
    {
        list_users.Add(new Users(dr));
    }
}
catch { /* error */ }
finally { cn.Close(); }

The User's constructor would do all the "dr.GetString(i)"

A more general solution that works with all the data frame at once and where you don't have to add new factors levels is:

data.mtx <- as.matrix(data.df)
data.mtx[which(data.mtx == "old.value.to.replace")] <- "new.value"
data.df <- as.data.frame(data.mtx)

A nice feature of this code is that you can assign as many values as you have in your original data frame at once, not only one "new.value", and the new values can be random values. Thus you can create a complete new random data frame with the same size as the original.

(My thanks and +1 vote to bodokaiser's answer).

As others have mentioned, a.update(b) for some dicts a and b will achieve the result you've asked for in your question. However, I want to point out that many times I have seen the extend method of mapping/set objects desire that in the syntax a.extend(b), a's values should NOT be overwritten by b's values. a.update(b) overwrites a's values, and so isn't a good choice for extend.

Note that some languages call this method defaults or inject, as it can be thought of as a way of injecting b's values (which might be a set of default values) in to a dictionary without overwriting values that might already exist.

Of course, you could simple note that a.extend(b) is nearly the same as b.update(a); a=b. To remove the assignment, you could do it thus:

def extend(a,b):
    """Create a new dictionary with a's properties extended by b,
    without overwriting.

    >>> extend({'a':1,'b':2},{'b':3,'c':4})
    {'a': 1, 'c': 4, 'b': 2}
    """
    return dict(b,**a)

Thanks to Tom Leys for that smart idea using a side-effect-less dict constructor for extend.

This is how i did it. I have a nav block that is below the header once you scroll the page down it 'sticks' to the top of the window. If you scroll back to top, nav goes back in it's place I use position:fixed in CSS for non mobile platforms and iOS5. Other Mobile versions do have that 'lag' until screen stops scrolling before it's set.

// css
#sticky.stick {
    width:100%;
    height:50px;
    position: fixed;
    top: 0;
    z-index: 1;
}

// jquery 
//sticky nav
    function sticky_relocate() {
      var window_top = $(window).scrollTop();
      var div_top = $('#sticky-anchor').offset().top;

      if (window_top > div_top)
        $('#sticky').addClass('stick');
      else
        $('#sticky').removeClass('stick');
     }

$(window).scroll(function(event){

    // sticky nav css NON mobile way
       sticky_relocate();

       var st = $(this).scrollTop();

    // sticky nav iPhone android mobile way iOS<5

       if (navigator.userAgent.match(/OS 5(_\d)+ like Mac OS X/i)) {
            //do nothing uses sticky_relocate() css
       } else if ( navigator.userAgent.match(/(iPod|iPhone|iPad)/i) || navigator.userAgent.match(/Android/i) || navigator.userAgent.match(/webOS/i) ) {

            var window_top = $(window).scrollTop();
            var div_top = $('#sticky-anchor').offset().top;

            if (window_top > div_top) {
                $('#sticky').css({'top' : st  , 'position' : 'absolute' });
            } else {
                $('#sticky').css({'top' : 'auto' });
            }
        };

About prototype bean(s) :

The client code must clean up prototype-scoped objects and release expensive resources that the prototype bean(s) are holding. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up.

ref : https://docs.spring.io/spring/docs/3.0.0.M3/reference/html/ch04s04.html#beans-factory-scopes-prototype

Here is another easy method to make the variable available in other functions without having to use global variables:

function makeObj() {_x000D_
  // var trailimage = 'test';_x000D_
  makeObj.trailimage = 'test';_x000D_
}_x000D_
function someOtherFunction() {_x000D_
  document.write(makeObj.trailimage);_x000D_
}_x000D_
_x000D_
makeObj();_x000D_
someOtherFunction();

A variable will never be an integer type in JavaScript — it doesn't distinguish between different types of Number.

You can test if the variable contains a number, and if that number is an integer.

(typeof foo === "number") && Math.floor(foo) === foo

If the variable might be a string containing an integer and you want to see if that is the case:

foo == parseInt(foo, 10)

I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.

SET @sql = '';
SELECT
    @sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
    SELECT
      DISTINCT
        CONCAT(
         'MAX(IF(pa.fieldname = ''',
          fieldname,
          ''', pa.fieldvalue, NULL)) AS ',
          fieldname
        ) as output
    FROM
        product_additional
) as temp;

SET @sql = CONCAT('SELECT p.id
                    , p.name
                    , p.description, ', @sql, ' 
                   FROM product p
                   LEFT JOIN product_additional AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Adding export PATH="/Users/<username>/anaconda/bin:$PATH" (or export PATH="/Users/<username>/anaconda3/bin:$PATH" if you have anaconda 3) to my ~/.bash_profile file, fixed this issue for me.

You have not joined TableD, merely selected the TableD FIELD (dID) from one of the tables.

As mentioned by other answers, as of now android studio does not provide this out of the box. However, there are ways to do this easily.

As mentioned by @Elad Lavi, you should consider cloud hosting of your source code. Checkout github, bitbucket, gitlab, etc. All these provide private repositories, some free, some not.

If all you want is to just zip the sources, you can achieve this using git's git archive. Here are the steps:

git init       # on the root of the project folder
git add .      # note: android studio already created .gitignore
git commit -m 'ready to zip sources'
git archive HEAD --format=zip > /tmp/archive.zip

Note: If you intend to send this by email, you have to remove gradlew.bat from zip file.

Both these solutions are possible thanks to VCS like git.

With second precision, you can print tv_sec field of timeval structure that you get from gettimeofday() function. For example:

#include <sys/time.h>
#include <stdio.h>

int main()
{
    struct timeval tv;
    gettimeofday(&tv, NULL);
    printf("Seconds since Jan. 1, 1970: %ld\n", tv.tv_sec);
    return 0;
}

Example of compiling and running:

$ gcc -Wall -o test ./test.c 
$ ./test 
Seconds since Jan. 1, 1970: 1343845834

Note, however, that its been a while since epoch and so long int is used to fit a number of seconds these days.

There are also functions to print human-readable times. See this manual page for details. Here goes an example using ctime():

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

int main()
{
    time_t clk = time(NULL);
    printf("%s", ctime(&clk));
    return 0;
}

Example run & output:

$ gcc -Wall -o test ./test.c 
$ ./test 
Wed Aug  1 14:43:23 2012
$

I did not like the Javascript Solution I saw above. Here is the one I build using partial applying, closures and recursion:

Ok, I was mainly concern about, if the combinations array could satisfy the target requirement, hopefully this approached you will start to find the rest of combinations

Here just set the target and pass the combinations array.

function main() {
    const target = 10
    const getPermutationThatSumT = setTarget(target)
    const permutation = getPermutationThatSumT([1, 4, 2, 5, 6, 7])

    console.log( permutation );
}

the currently implementation I came up with

function setTarget(target) {
    let partial = [];

    return function permute(input) {
        let i, removed;
        for (i = 0; i < input.length; i++) {
            removed = input.splice(i, 1)[0];
            partial.push(removed);

            const sum = partial.reduce((a, b) => a + b)
            if (sum === target) return partial.slice()
            if (sum < target) permute(input)

            input.splice(i, 0, removed);
            partial.pop();
        }
        return null
    };
}

Some great examples and libs presented in this thread, but they didn't quite have what I was looking for. My approach: angular-validity -- a promise based validation lib for asynchronous validation, with optional Bootstrap styling baked-in.

An angular-validity solution for the OP's use case might look something like this:

<input  type="text" name="field4" ng-model="field4"
        validity="eval"
        validity-eval="!(field1 && field2 && field3 && !field4)"
        validity-message-eval="This field is required">

Here's a Fiddle, if you want to take it for a spin. The lib is available on GitHub, has detailed documentation, and plenty of live demos.

I ran into the same issue with Go11, just wanted to share how I did solve it for helping others just in case they run into the same issue.

I had my Go project outside $GOPATH, so I had to turned on GO111MODULE=on without this option turned on, it will give you this issue; even if you you try to build or test the whole package or directory it won't be solved without GO111MODULE=on

Rails has some built in helpers that might solve this for you. One thing to keep in mind is that this is part of the Actionview Helpers, so they wont be available directly from the console.

Try this

<% start_time =  "2012-03-02 14:46:21 +0100" %>
<% end_time   =  "2012-04-02 14:46:21 +0200" %>
<%= distance_of_time_in_words(start_time, end_time)  %>

 "about 1 month"

If all the other answers didn't work for you, try disabling HTTP input encoding translation.

HTML5: Permitted Values for ID & Class Attributes

As of HTML5, the only restrictions on the value of an ID are:

1. must be unique in the document
2. must not contain any space characters
3. must contain at least one character

Similar rules apply to classes (except for the uniqueness, of course).

So the value can be all digits, just one digit, just punctuation characters, include special characters, whatever. Just no whitespace. This is very different from HTML4.

In HTML 4, ID values must begin with a letter, which can then be followed only by letters, digits, hyphens, underscores, colons and periods.

In HTML5 these are valid:

<div id="999"> ... </div>
<div id="#%LV-||"> ... </div>
<div id="____V"> ... </div>
<div id="??"> ... </div>
<div id="?"> ... </div>
<div id="{}"> ... </div>
<div id="©"> ... </div>
<div id="??¤?€~¥"> ... </div>

Just bear in mind that using numbers, punctuation or special characters in the value of an ID may cause trouble in other contexts (e.g., CSS, JavaScript, regex).

For example, the following ID is valid in HTML5:

<div id="9lions"> ... </div>

However, it is invalid in CSS:

From the CSS2.1 spec:

4.1.3 Characters and case

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.

In most cases you may be able to escape characters in contexts where they have restrictions or special meaning.

W3C References

HTML5

3.2.5.1 The id attribute

The id attribute specifies its element's unique identifier (ID).

The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.

Note: There are no other restrictions on what form an ID can take; in particular, IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc.

3.2.5.7 The class attribute

The attribute, if specified, must have a value that is a set of space-separated tokens representing the various classes that the element belongs to.

The classes that an HTML element has assigned to it consists of all the classes returned when the value of the class attribute is split on spaces. (Duplicates are ignored.)

There are no additional restrictions on the tokens authors can use in the class attribute, but authors are encouraged to use values that describe the nature of the content, rather than values that describe the desired presentation of the content.

If using jQuery, this seems to work:

$('#your_iframe').attr('src', $('#your_iframe').attr('src'));

I hope it's not too ugly for stackoverflow.

You could use:

Dim MyForm As New Form1
MyForm.Show()

or rather:

MyForm.ShowDialog()

to open the form as a dialog box to ensure that user interacts with the new form or closes it.

If you wanted to return a replaced result, then this would work:

var a = 'Test123*** TEST';
var b = a.replace(/[^a-z0-9]/gi,'');
console.log(b);

This would return:

Test123TEST

Note that the gi is necessary because it means global (not just on the first match), and case-insensitive, which is why I have a-z instead of a-zA-Z. And the ^ inside the brackets means "anything not in these brackets".

WARNING: Alphanumeric is great if that's exactly what you want. But if you're using this in an international market on like a person's name or geographical area, then you need to account for unicode characters, which this won't do. For instance, if you have a name like "Âlvarö", it would make it "lvar".

As others have answered, the mysqli API can execute multi-queries with the msyqli_multi_query() function.

For what it's worth, PDO supports multi-query by default, and you can iterate over the multiple result sets of your multiple queries:

$stmt = $dbh->prepare("
    select sql_calc_found_rows * from foo limit 1 ; 
    select found_rows()");
$stmt->execute();
do {
  while ($row = $stmt->fetch()) {
    print_r($row);
  }
} while ($stmt->nextRowset());

However, multi-query is pretty widely considered a bad idea for security reasons. If you aren't careful about how you construct your query strings, you can actually get the exact type of SQL injection vulnerability shown in the classic "Little Bobby Tables" XKCD cartoon. When using an API that restrict you to single-query, that can't happen.

It's Really Simple Just go to your styles.xml change the parent Theme to either Theme.AppCompat.Light.NoActionBar or Theme.AppCompat.NoActionbar and you are done.. :)

You can use the wget --user=USER --password=PASSWORD .. command, but before you can do that, you must allow artifactory to force authentication, which can be done by unchecking the "Hide Existence of Unauthorized Resources" box at Security/General tab in artifactory admin panel. Otherwise artifactory sends a 404 page and wget can not authenticate to artifactory.

Just an update to the Java 8 version

public Map<String, List<String>> splitQuery(URL url) {
    if (Strings.isNullOrEmpty(url.getQuery())) {
        return Collections.emptyMap();
    }
    return Arrays.stream(url.getQuery().split("&"))
            .map(this::splitQueryParameter)
            .collect(Collectors.groupingBy(SimpleImmutableEntry::getKey, LinkedHashMap::new, **Collectors**.mapping(Map.Entry::getValue, **Collectors**.toList())));
}

mapping and toList() methods have to be used with Collectors which was not mentioned in the top answer. Otherwise it would throw compilation error in IDE

I suggest to place invisible(opacity = 0) button on your imageview and then handle interaction on button.

EDIT: As pointed out in the comments, this is not the correct answer to the OPs question, but it is useful to know this command. This question showed up in Google for what I was looking for, and figured I'd leave this answer for the others to find.

SHOW CREATE TABLE `<yourtable>`;

I found this answer here: MySQL : show constraints on tables command

I needed this way because I wanted to see how the FK functioned, rather than just see if it existed or not.

Another way is to use the powers of /usr/bin/env:

docker run ubuntu env DEBUG=1 path/to/script.sh

In v1.43 is the ability to separately color the vertical rulers.

See issue Support multiple rulers with different colors - (in settings.json):

  },
  100,  // <- a ruler in the default color or as customized (with "editorRuler.foreground") at column 100
  {
    "column": 120,
    "color": "#ff0000"
  },
], 

From the Intel Instructions

"The SDK Manager will download the installer to the "extras" directory, under the main SDK directory. Even though the SDK manager says "Installed" it actually means that the Intel HAXM executable was downloaded. You will still need to run the installer from the "extras" directory to finish installation.

Extract the installer inside the "extras" directory and follow the installation instructions for your platform."

You should be able to use the DataTable.Select() method. You can us it like this.

if(myDataTable.Select("Author = '" + AuthorName.Replace("'","''") + '").Length > 0)
    ...

The Select() funciton returns an array of DataRows for the results matching the where statement.

You can use

insert into <table_name> select <fieldlist> from <tables>

SELECT *
   FROM   my_table
   WHERE  substr(my_field,1,5) = "abcde";

i had a same issue because of my Nvidea Graphics card Driver Problem.

If your System has Dedicated Graphics card then Check for the latest Driver and Install it.

Other wise simply Choose Emulated Performance as Software in Emulator Configurations

After Updating the driver the issue is resolved :)

After I updated my MySql, I was getting the same error message. It turned out that after installing a different version on MySql, inside the my.ini, the port was different. Previous MySql version had port 3306 but the new one have port 3308. Check your MySql my.ini, if it is different use the port from .ini in your connection.

It should be saved. It should be like this :

     db. my_collection.find({}).forEach(function(theCollection) {
         theCollection.moop = parseInt(theCollection.moop);
        db.my_collection.save(theCollection);
     });

If you want to delete a commit you can do it as part of an interactive rebase. But do it with caution, so you don't end up messing up your repo.

In Sourcetree:

1. Right click a commit that's older than the one you want to delete, and choose "Rebase children of xxxx interactively...". The one you click will be your "base" and you can make changes to every commit made after that one.

2. In the new window, select the commit you want gone, and press the "Delete"-button at the bottom, or right click the commit and click "Delete commit".
3. List item
4. Click "OK" (or "Cancel" if you want to abort).

Check out this Atlassian blog post for more on interactive rebasing in Sourcetree.

Yes. There are two kinds of types in .NET: reference types and value types.

References types (generally classes) are always referred to by references, so they support null without any extra work. This means that if a variable's type is a reference type, the variable is automatically a reference.

Value types (e.g. int) by default do not have a concept of null. However, there is a wrapper for them called Nullable. This enables you to encapsulate the non-nullable value type and include null information.

The usage is slightly different, though.

// Both of these types mean the same thing, the ? is just C# shorthand.
private void Example(int? arg1, Nullable<int> arg2)
{
    if (arg1.HasValue)
        DoSomething();

    arg1 = null; // Valid.
    arg1 = 123;  // Also valid.

    DoSomethingWithInt(arg1); // NOT valid!
    DoSomethingWithInt(arg1.Value); // Valid.
}

I had the same issue as OP but none of the current answers solved my issue so to add a slightly different answer that did work for me:

Running Python 3.6.5 on a Windows Machine, I used the format

r"\DriveName\then\file\path\txt.md"

so the combination of double backslashes from reading @Johnsyweb UNC link and adding the r in front as recommended solved my similar to OP's issue.

Short answer: You can't.

CSS does not have techniques which affect the rendering of fonts in the browser; only the system can do that.

Obviously, text sharpness can easily be achieved with pixel-dense screens, but if you're using a normal PC that's gonna be hard to achieve.

There are some newer fonts that are smooth but at the sacrifice of it appearing somewhat blurry (look at most of Adobe's fonts, for example). You can also find some smooth-but-blurry-by-design fonts at Google Fonts, however.

There are some new CSS3 techniques for font rendering and text effects though the consistency, performance, and reliability of these techniques vary so largely to the point where you generally shouldn't rely on them too much.

Note that the % syntax for formatting strings is becoming outdated. If your version of Python supports it, you should write:

instr = "'{0}', '{1}', '{2}', '{3}', '{4}', '{5}', '{6}'".format(softname, procversion, int(percent), exe, description, company, procurl)

This also fixes the error that you happened to have.

javascript function for client side validation (using jQuery)...

function CheckBoxRequired_ClientValidate(sender, e)
{
    e.IsValid = jQuery(".AcceptedAgreement input:checkbox").is(':checked');
}

code-behind for server side validation...

protected void CheckBoxRequired_ServerValidate(object sender, ServerValidateEventArgs e)
{
    e.IsValid = MyCheckBox.Checked;
}

ASP.Net code for the checkbox & validator...

<asp:CheckBox runat="server" ID="MyCheckBox" CssClass="AcceptedAgreement" />
<asp:CustomValidator runat="server" ID="CheckBoxRequired" EnableClientScript="true"
    OnServerValidate="CheckBoxRequired_ServerValidate"
    ClientValidationFunction="CheckBoxRequired_ClientValidate">You must select this box to proceed.</asp:CustomValidator>

and finally, in your postback - whether from a button or whatever...

if (Page.IsValid)
{
    // your code here...
}

If you are using NumPy arrays, shape can be used. For example

  >>> a = numpy.array([[[1,2,3],[1,2,3]],[[12,3,4],[2,1,3]]])
  >>> a
  array([[[ 1,  2,  3],
         [ 1,  2,  3]],

         [[12,  3,  4],
         [ 2,  1,  3]]])
 >>> a.shape
 (2, 2, 3)

You can also use the following trick:

y.x = "some custom property"//gives typescript error

y["x"] = "some custom property"//no errors

Note, that to access x and dont get a typescript error again you need to write it like that y["x"], not y.x. So from this perspective the other options are better.

I think Sanjay's answer was almost there but i used it this way

NSArray *myArray = [[NSArray alloc] initWithObjects:@"Hello",@"World", nil];
NSString *greeting = [myArray componentsJoinedByString:@" "];
NSLog(@"%@",greeting);

Output :

2015-01-25 08:47:14.830 StringTest[11639:394302] Hello World

As Sanjay had hinted - I used method componentsJoinedByString from NSArray that does joining and gives you back NSString

BTW NSString has reverse method componentsSeparatedByString that does the splitting and gives you NSArray back .

Through the this steps you can .

1. In Eclipse , Right Click on Project from Package Explorer.
2. Select Properties,.
3. Select Android from Properties pop up window,
4. See "Is Library" check box,
5. If it is checked then Unchecked "Is Library" check box.
6. Click Apply and than OK.

You should use a sticky footer solution such as this one :

* {
    margin: 0;
}
html, body {
    height: 100%;
}
.wrapper {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -142px; /* the bottom margin is the negative value of the footer's height */
}
.footer, .push {
    height: 142px; /* .push must be the same height as .footer */
}

There are others like this;

* {margin:0;padding:0;} 

/* must declare 0 margins on everything, also for main layout components use padding, not 
vertical margins (top and bottom) to add spacing, else those margins get added to total height 
and your footer gets pushed down a bit more, creating vertical scroll bars in the browser */

html, body, #wrap {height: 100%;}

body > #wrap {height: auto; min-height: 100%;}

#main {padding-bottom: 150px;}  /* must be same height as the footer */

#footer {position: relative;
    margin-top: -150px; /* negative value of footer height */
    height: 150px;
    clear:both;} 

/* CLEAR FIX*/
.clearfix:after {content: ".";
    display: block;
    height: 0;
    clear: both;
    visibility: hidden;}
.clearfix {display: inline-block;}
/* Hides from IE-mac \*/
* html .clearfix { height: 1%;}
.clearfix {display: block;}

with the html:

<div id="wrap">

    <div id="main" class="clearfix">

    </div>

</div>

<div id="footer">

</div>

Presumably you have it in a variable and are using JSON.parse(data);. In which case, use:

JSON.parse(data.replace(/"/g,'"'));

You might want to fix your JSON-writing script though, because " is not valid in a JSON object.

This might just help someone, in addition to what other answers have mentioned.

Clear the contents of AppData\Local\Microsoft\WebSiteCache folder.

In my case I had VS 2015 pro update 3 and this is what helped me speed up VS.

To use this function/method,you need an instance of the class Date .

This method is always used in conjunction with a Date object.

See the code below :

var d = new Date();
d.getTime();

Link : http://www.w3schools.com/jsref/jsref_getTime.asp

$date = "Mar 03, 2011";
$date = strtotime($date);
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

Very simple:

setlocal
cd /d %~dp0
File.exe

Type "Sysout" and then Ctrl+Space. It expands to

System.out.println();

The easiest way to overwrite a text file is to use a public static field.

this will overwrite the file every time because your only using false the first time through.`

public static boolean appendFile;

Use it to allow only one time through the write sequence for the append field of the write code to be false.

// use your field before processing the write code

appendFile = False;

File fnew=new File("../playlist/"+existingPlaylist.getText()+".txt");
String source = textArea.getText();
System.out.println(source);
FileWriter f2;

try {
     //change this line to read this

    // f2 = new FileWriter(fnew,false);

    // to read this
    f2 = new FileWriter(fnew,appendFile); // important part
    f2.write(source);

    // change field back to true so the rest of the new data will
    // append to the new file.

    appendFile = true;

    f2.close();
 } catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
 }           

Create php.ini file with your desired setting and upload it in your root folder of server. It will take effect with this new setting.

You can't edit the php.ini file of godaddy server, but you can upload your own copy of your php.ini with your new setting.

This new setting will be available only to you. Other websites will not be affected with this new setting.

Previously I faced the same issue, but after doing this my problem was resolved.

Using print without parentheses in Python 3 code is not a good idea. Nor is creating aliases, etc. If that's a deal breaker, use Python 2.

However, print without parentheses might be useful in the interactive shell. It's not really a matter of reducing the number of characters, but rather avoiding the need to press Shift twice every time you want to print something while you're debugging. IPython lets you call functions without using parentheses if you start the line with a slash:

Python 3.6.6 (default, Jun 28 2018, 05:43:53)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.4.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: var = 'Hello world'

In [2]: /print var
Hello world

And if you turn on autocall, you won't even need to type the slash:

In [3]: %autocall
Automatic calling is: Smart

In [4]: print var
------> print(var)
Hello world

In BBEdit works this (ex.: changing the ID values to lowercase):

Search any value: <a id="(?P<x>.*?)"></a> Replace with the same in lowercase: <a id="\L\P<x>\E"></a>

Was: <a id="VALUE"></a> Became: <a id="value"></a>

If your array has a natural order use binary search.

Use binary search.

Binary search has O(log n) access time.

Here are the steps on how to use binary search,

• What is the ordering of you array? For example, is it sorted by name?
• Use bsearch to find elements or indices

Code example

# assume array is sorted by name!

array.bsearch { |each| "Jamie" <=> each.name } # returns element
(0..array.size).bsearch { |n| "Jamie" <=> array[n].name } # returns index

You can use the following code;

var example: String = "Hello World \r\n This is a new line"

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

Stream stream = new MemoryStream();

you can use MemoryStream

Reference: MemoryStream

DOMSubtreeModified is not a good solution. It's can cause infinite loops if you decide to change the DOM inside the event handler, hence it has been disabled in a number of browsers. MutationObserver will be the answer.

MDN Doc

const onChangeElement = (qSelector, cb)=>{
 const targetNode = document.querySelector(qSelector);
 if(targetNode){
    const config = { attributes: true, childList: false, subtree: false };
    const callback = function(mutationsList, observer) {
        cb($(qSelector))
    };
    const observer = new MutationObserver(callback);
    observer.observe(targetNode, config);
 }else {
    console.error("onChangeElement: Invalid Selector")
 }
}

And you can use it,

onChangeElement('mydiv', function(jqueryElement){
   alert('changed')
})

Would this help?

final List<String> l = new ArrayList<String>();
for (int i = 0; i < 10; i++) l.add("Number " + i);
for (int i = 0; i < 10; i++) System.out.println(l.get(i));

sup {
    line-height: 0;

    /* The following rules (or similar) likely come from browser 
     * style and are not needed
     */
    font-size: 0.83em;
    vertical-align: super;
}

The trick is to set the <sup>'s line-height to 0. @Scott said to use normal, but this doesn't always work.

This means you don't have to change the line-height of surrounding text to accommodate the superscript text. I've tested this in IE7+ and the other major browsers.

I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.

A version that supports finding the column names and types of a table in a specific schema, and uses JOINs without any subqueries

    pg_attribute.attname AS column_name,

FROM
    pg_catalog.pg_attribute
INNER JOIN
    pg_catalog.pg_class ON pg_class.oid = pg_attribute.attrelid
INNER JOIN
    pg_catalog.pg_namespace ON pg_namespace.oid = pg_class.relnamespace
WHERE
    pg_attribute.attnum > 0

    AND pg_namespace.nspname = 'my_schema'
    AND pg_class.relname = 'my_table'
ORDER BY
    attnum ASC;

The question is specific to SQL Server, but I would like to extend Martin Smith's answer.

SQL:2003 standard allows to define multiple values for simple case expression:

SELECT CASE c.Number
          WHEN '1121231','31242323' THEN 1
          WHEN '234523','2342423' THEN 2
       END AS Test
FROM tblClient c;

It is optional feature: Comma-separated predicates in simple CASE expression“ (F263).

Syntax:

CASE <common operand>
     WHEN <expression>[, <expression> ...] THEN <result>
    [WHEN <expression>[, <expression> ...] THEN <result>
     ...]
    [ELSE <result>]
END

As for know I am not aware of any RDBMS that actually supports that syntax.

I just published a command line interface utility to npm and github that allows you to copy keys that match a given pattern (even *) from one Redis database to another.

You can find the utility here:

https://www.npmjs.com/package/redis-utils-cli

I faced the similar problem, a workaround is to open up a terminal, go to project folder and run

java cp target/<your_jar_artifact.jar> <com.your_package.YourMainClass>

If you like to do this for open files on Notepad++, you can use Combine plugin: http://www.scout-soft.com/combine/

What is a when you call Ancestors('A',a)? If a['A'] is None, or if a['A'][0] is None, you'd receive that exception.

Here is your answer. use

                   jquery.json-2.2.min.js 
                      and
                   jquery-1.8.3.min.js

Javascript :

function CallAddToCart(eitemId, equantity) {
   var itemId = Number(eitemId);
   var quantity = equantity;
   var dataValue = "{itemId:'" + itemId+ "', quantity :'"+ quantity "'}" ;
    $.ajax({
           url: "AddToCart.aspx/AddTo_Cart",
           type: "POST",
           dataType: "json",
           data: dataValue,
           contentType: "application/json; charset=utf-8",
           success: function (msg) {
                alert("Success");
           },
           error: function () { alert(arguments[2]); }      
        });
 }

and your C# web method should be

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string AddTo_Cart(int itemId, string quantity)
{
   SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
  return "Item Added Successfully";
}

From any of the button click or any other html control event you can call to the javascript method with the parameter which in turn calls to the webmethod to get the value in json format.

As @milosmns said, you should use imageView.setColorFilter(getResouces().getColor(R.color.blue),android.graphics.PorterDuff.Mode.MULTIPLY);

This API need color value instead of color resource id, That's the root cause why your statement didn't work.

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

There's typically two levels of buffering involved:

1. Internal buffers
2. Operating system buffers

The internal buffers are buffers created by the runtime/library/language that you're programming against and is meant to speed things up by avoiding system calls for every write. Instead, when you write to a file object, you write into its buffer, and whenever the buffer fills up, the data is written to the actual file using system calls.

However, due to the operating system buffers, this might not mean that the data is written to disk. It may just mean that the data is copied from the buffers maintained by your runtime into the buffers maintained by the operating system.

If you write something, and it ends up in the buffer (only), and the power is cut to your machine, that data is not on disk when the machine turns off.

So, in order to help with that you have the flush and fsync methods, on their respective objects.

The first, flush, will simply write out any data that lingers in a program buffer to the actual file. Typically this means that the data will be copied from the program buffer to the operating system buffer.

Specifically what this means is that if another process has that same file open for reading, it will be able to access the data you just flushed to the file. However, it does not necessarily mean it has been "permanently" stored on disk.

To do that, you need to call the os.fsync method which ensures all operating system buffers are synchronized with the storage devices they're for, in other words, that method will copy data from the operating system buffers to the disk.

Typically you don't need to bother with either method, but if you're in a scenario where paranoia about what actually ends up on disk is a good thing, you should make both calls as instructed.

Addendum in 2018.

Note that disks with cache mechanisms is now much more common than back in 2013, so now there are even more levels of caching and buffers involved. I assume these buffers will be handled by the sync/flush calls as well, but I don't really know.

1. Try to avoid globals. If you must use a global, see the other answers.
2. Pass it as an argument to a function.

Delete the .refresh.dll file if you are under source control. Then rebuild. It should work. This worked for me

Simple solution

Just add --network=host to docker run. That's all!

This way container will use the host's network, so localhost and 127.0.0.1 will point to the host (by default they point to a container). Example:

docker run -d --network=host \
  -e "DB_DBNAME=your_db" \
  -e "DB_PORT=5432" \
  -e "DB_USER=your_db_user" \
  -e "DB_PASS=your_db_password" \
  -e "DB_HOST=127.0.0.1" \
  --name foobar foo/bar

you could try this:

I have these two columns (column "A" and column "B"). I want to color them when the values between cells in the same row mismatch.

Follow these steps:

1. Select the elements in column "A" (excluding A1);

2. Click on "Conditional formatting -> New Rule -> Use a formula to determine which cells to format";

3. Insert the following formula: =IF(A2<>B2;1;0);

4. Select the format options and click "OK";

5. Select the elements in column "B" (excluding B1) and repeat the steps from 2 to 4.

It depends on how precise you want to be. It you want to accept only integers, than:

<input type="number" min="1" step="1">

If you want floats with, for example, two digits after decimal point:

<input type="number" min="0.01" step="0.01">

Plain old JavaScript will suffice - jQuery is not necessary for such a simple task:

var myString = "data-123";
var myNewString = myString.replace("data-", "");

See: .replace() docs on MDN for additional information and usage.

You definitely need to put in the column order, otherwise how is SQL Server supposed to know which one goes first? Here's what you would need to do in your code:

public class MyTable
{
  [Key, Column(Order = 0)]
  public string SomeId { get; set; }

  [Key, Column(Order = 1)]
  public int OtherId { get; set; }
}

You can also look at this SO question. If you want official documentation, I would recommend looking at the official EF website. Hope this helps.

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12

611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

Delete data that is 30 days and older

   DELETE FROM Table
   WHERE DateColumn < GETDATE()- 30

Simply add default 0 at the end of your ALTER TABLE <table> ADD COLUMN <column> <type> statement

Bootstrap 4 to hide whole content use this class '.d-none' it will be hide everything regardless of breakpoints same like previous bootstrap version class '.hidden'

according to GSON User guide, you cannot.

Collections Limitations

Can serialize collection of arbitrary objects but can not deserialize from it. Because there is no way for the user to indicate the type of the resulting object

Nice one-liner HTML only:

 <input type="text" id='nameInput' onkeypress='return ((event.charCode >= 65 && event.charCode <= 90) || (event.charCode >= 97 && event.charCode <= 122) || (event.charCode == 32))'>

I've found a bug in the official CLEARFIX-Method: The DOT doesn't have a font-size. And if you set the height = 0 and the first Element in your DOM-Tree has the class "clearfix" you'll allways have a margin at the bottom of the page of 12px :)

You have to fix it like this:

/* float clearing for everyone else */
.clearfix:after{
  clear: both;
  content: ".";
  display: block;
  height: 0;
  visibility: hidden;
  font-size: 0;
}

It's now part of the YAML-Layout ... Just take a look at it - it's very interesting! http://www.yaml.de/en/home.html

For the record, none of the aforementioned Git Python libraries seem to contain a "git status" equivalent, which is really the only thing I would want since dealing with the rest of the git commands via subprocess is so easy.

Try to use constructor procedure in your class.

Object.assign

is a key

Please take a look on this sample:

class Employee{
    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;
    permissions: string;
    typeOfEmployee: string;
    note: string;
    lastUpdate: Date;

    constructor(original: Object) { 
        Object.assign(this, original);
    }
}

let e = new Employee({
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 3,
    "username": "<anystring>",
    "permissions": "<anystring>",
    "lastUpdate": "<anydate>"
});
console.log(e);

This worked for me. Create WebViewClient like this below and set the webclient to your webview. I had to use webview.loadDataWithBaseURL as my urls (in my content) did not have the baseurl but only relative urls. You will get the url correctly only when there is a baseurl set using loadDataWithBaseURL.

public WebViewClient getWebViewClientWithCustomHeader(){
    return new WebViewClient() {
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
            try {
                OkHttpClient httpClient = new OkHttpClient();
                com.squareup.okhttp.Request request = new com.squareup.okhttp.Request.Builder()
                        .url(url.trim())
                        .addHeader("<your-custom-header-name>", "<your-custom-header-value>")
                        .build();
                com.squareup.okhttp.Response response = httpClient.newCall(request).execute();

                return new WebResourceResponse(
                        response.header("content-type", response.body().contentType().type()), // You can set something other as default content-type
                        response.header("content-encoding", "utf-8"),  // Again, you can set another encoding as default
                        response.body().byteStream()
                );
            } catch (ClientProtocolException e) {
                //return null to tell WebView we failed to fetch it WebView should try again.
                return null;
            } catch (IOException e) {
                //return null to tell WebView we failed to fetch it WebView should try again.
                return null;
            }
        }
    };

}

this is actually pretty easily done. You're almost there, doing what you've done with background-position: right center;. What is actually needed in this case is something very much like that. Let's convert these to percentages. We know that center=50%, so that's easy enough. Now, in order to get the padding you wanted, you need to position the background like so: background-position: 99% 50%.

The second, and more effective way of going about this, is to use the same background-position idea, and just use background-position: 400px (width of parent) 50%;. Of course, this method requires a static width, but will give you the same thing every time.

Method 1 (99% 50%)
Method 2 (400px 50%)

Here's the complete answer for the future reader. Note that this is only possible in Laravel 5+.

First of all you'll need the doctrine/dbal package:

composer require doctrine/dbal

Now in your migration you can do this to make the column nullable:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

You may be wondering how to revert this operation. Sadly this syntax is not supported:

// Sadly does not work :'(
$table->integer('user_id')->unsigned()->change();

This is the correct syntax to revert the migration:

$table->integer('user_id')->unsigned()->nullable(false)->change();

Or, if you prefer, you can write a raw query:

public function down()
{
    /* Make user_id un-nullable */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
}

Hopefully you'll find this answer useful. :)

This is not a complete answer to the question (for the technical answer please refer to @Zze's answer above), but there's an important step that needs to be added:

COMPATIBILITY MODE

Even with the appropriate polyfills in place, there are still issues with running Angular 2+ apps using the polyfills on IE11. If you are running the site off an intranet host (ie. if you are testing it at http://localhost or another mapped local domain name), you must go into Compatibility View settings and uncheck "Display intranet sites in Compatibility View", since IE11's Compatibility View breaks a couple of the conventions included in the ES5 polyfills for Angular.

I used the construction of $.each (data [i], function (key, value) But you must pre-match the names of the selection fields with the names of the form elements. Then, in the loop after "success", autocomplete elements from the "data" array. Did this: autocomplete form with ajax success

Numeric defines the TOTAL number of digits, and then the number after the decimal.

A numeric(3,2) can only hold up to 9.99.

In Addition

When migration you deployed long ago does not let you migrate new one.

What happened is, I work in a larger Rails app with more than a thousand of migration files. And, it takes a month for us to ship a medium-sized feature. I was working on a feature and I had deployed a migration a month ago then in the review process the structure of migration and filename changed, now I try to deploy my new code, the build failed saying

ActiveRecord::StatementInvalid: PG::DuplicateColumn: ERROR:  column "my_new_field" of relation "accounts" already exists

none of the above-mentioned solutions worked for me because the old migration file was missing and the field I intended to create in my new migration file already existed in the DB. The only solution that worked for me is:

1. I scped the file to the server
2. I opened the rails console
3. I required the file in the IRB session
4. then AddNewMyNewFieldToAccounts.new.down

then I could run the deploy build again.

Hope it helps you too.

In laravel 6 the latest one can easily add in the "APP/user.php" model:

/**
 * The storage format of the model's date columns.
 *
 * @var string
 */
protected $dateFormat = 'U';

And in schema one can add

    $table->integer('created_at')->nullable();
    $table->integer('updated_at')->nullable();

You're setting the global git options, but the local checkout possibly has overrides set. Try setting them again with git config --local <setting> <value>. You can look at the .git/config file in your local checkout to see what local settings the checkout has defined.

cv2 uses numpy for manipulating images, so the proper and best way to get the size of an image is using numpy.shape. Assuming you are working with BGR images, here is an example:

>>> import numpy as np
>>> import cv2
>>> img = cv2.imread('foo.jpg')
>>> height, width, channels = img.shape
>>> print height, width, channels
  600 800 3

In case you were working with binary images, img will have two dimensions, and therefore you must change the code to: height, width = img.shape

Use the "has attribute" selector:

$('p[MyTag]')

Or to select one where that attribute has a specific value:

$('p[MyTag="Sara"]')

There are other selectors for "attribute value starts with", "attribute value contains", etc.

Like This:

[1,2,3,4].join('; ')

Use a Border of height 1 and don't set the Width (i.e. Width = Auto, HorizontalAlignment = Stretch, the default)

Java 9 & Unified JVM Logging

JEP 158 introduces a common logging system for all components of the JVM which will change (and IMO simplify) how logging works with GC. JEP 158 added a new command-line option to control logging from all components of the JVM:

-Xlog

For example, the following option:

-Xlog:gc

will log messages tagged with gc tag using info level to stdout. Or this one:

-Xlog:gc=debug:file=gc.txt:none

would log messages tagged with gc tag using debug level to a file called gc.txt with no decorations. For more detailed discussion, you can checkout the examples in the JEP page.

xlBook.Save();
xlBook.Close(true);
xlApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);

try this.. it worked for me... you should release that xl application object to stop the process.

I have come across other similar question here. Both of above answers are perfect, but here trying to add additional information for someone looking for SOAP1.1, and not SOAP1.2.

Just change one line code provided by @acdcjunior, use SOAPMessageFactory1_1Impl implementation, it will change namespace to xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/", which is SOAP1.1 implementation.

Change callSoapWebService method first line to following.

SOAPMessage soapMessage = SOAPMessageFactory1_1Impl.newInstance().createMessage();

I hope it will be helpful to others.

Drag the variable from Variables pane to Watch pane and voila!

$currentDateTime = $row['date'];
echo $newDateTime = date('l jS \of F Y h:i:s A', strtotime($currentDateTime));

I am using Google appengine java sdk and was facing similar issue. I had to add

<runtime>java8</runtime>

in appengine-web.xml file to make it work.

I prefer /^\s+$|^$/gi to match empty and empty spaces.

console.log("  ".match(/^\s+$|^$/gi));_x000D_
console.log("".match(/^\s+$|^$/gi));

HTML

<div class="outside">
  <div class="inside">
      <p>Centered Text</p>
  </div>
</div>

CSS

.outside { 
  position: absolute; 
  display: table; 
}

.inside {
  display: table-cell; 
  vertical-align: middle; 
  text-align: center; 
}

For %F In ("C:\From\*.*") Do If Not Exist "C:\To\%~nxF" Copy "%F" "C:\To\%~nxF"

For browsers supporting Object.keys() you can simply do:

Object.keys(a).length;

Otherwise (notably in IE < 9), you can loop through the object yourself with a for (x in y) loop:

var count = 0;
var i;

for (i in a) {
    if (a.hasOwnProperty(i)) {
        count++;
    }
}

The hasOwnProperty is there to make sure that you're only counting properties from the object literal, and not properties it "inherits" from its prototype.

This works fine in LINQPad4:

Console.WriteLine(DateTime.Parse("2010-08-20T15:00:00Z"));
Console.WriteLine(DateTime.Parse("2010-08-20T15:00:00"));
Console.WriteLine(DateTime.Parse("2010-08-20 15:00:00"));

Sometimes its because of ssh. So you can use this:

git clone https://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts

instead of:

git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts

Instead use use appendTo. append or appendTo returns a jQuery object so you don't have to wrap it inside $().

var holdyDiv = $('<div />').appendTo('body');
holdyDiv.attr('id', 'holdy');

.appendTo() reference: http://api.jquery.com/appendTo/

Alernatively you can try this also.

$('<div />', { id: 'holdy' }).appendTo('body');
               ^
             (Here you can specify any attribute/value pair you want)

All of the answers above are correct, for the case of DISTINCT on a single column vs GROUP BY on a single column. Every db engine has its own implementation and optimizations, and if you care about the very little difference (in most cases) then you have to test against specific server AND specific version! As implementations may change...

BUT, if you select more than one column in the query, then the DISTINCT is essentially different! Because in this case it will compare ALL columns of all rows, instead of just one column.

So if you have something like:

// This will NOT return unique by [id], but unique by (id,name)
SELECT DISTINCT id, name FROM some_query_with_joins

// This will select unique by [id].
SELECT id, name FROM some_query_with_joins GROUP BY id

It is a common mistake to think that DISTINCT keyword distinguishes rows by the first column you specified, but the DISTINCT is a general keyword in this manner.

So people you have to be careful not to take the answers above as correct for all cases... You might get confused and get the wrong results while all you wanted was to optimize!

Apart from the information given by David M. Lloyd one could add that the mechanism that allows this is called target typing.

The idea is that the type the compiler assigns to a lambda expressions or a method references does not depend only on the expression itself, but also on where it is used.

The target of an expression is the variable to which its result is assigned or the parameter to which its result is passed.

Lambda expressions and method references are assigned a type which matches the type of their target, if such a type can be found.

See the Type Inference section in the Java Tutorial for more information.

Another way to rename the database or taking image of the database is by using Reverse engineering option in the database tab. It will create a ERR diagram for the database. Rename the schema there.

after that go to file menu and go to export and forward engineer the database.

Then you can import the database.

It depends on how much content your website has. At first I used a database like all other people here, but it can be time-consuming to script all the workings of a database. I don't say that this is an ideal method and especially if you have a lot of text, but if you want to do it fast without using a database, this method could work, though, you can't allow users to input data which will be used as translation-files. But if you add the translations yourself, it will work:

Let's say you have this text:

Welcome!

You can input this in a database with translations, but you can also do this:

$welcome = array(
"English"=>"Welcome!",
"German"=>"Willkommen!",
"French"=>"Bienvenue!",
"Turkish"=>"Hosgeldiniz!",
"Russian"=>"????? ??????????!",
"Dutch"=>"Welkom!",
"Swedish"=>"Välkommen!",
"Basque"=>"Ongietorri!",
"Spanish"=>"Bienvenito!"
"Welsh"=>"Croeso!");

Now, if your website uses a cookie, you have this for example:

$_COOKIE['language'];

To make it easy let's transform it in a code which can easily be used:

$language=$_COOKIE['language'];

If your cookie language is Welsh and you have this piece of code:

echo $welcome[$language];

The result of this will be:

Croeso!

If you need to add a lot of translations for your website and a database is too consuming, using an array can be an ideal solution.

By default structs do not have a == operator. You'll have to write your own implementation:

bool MyStruct1::operator==(const MyStruct1 &other) const {
    ...  // Compare the values, and return a bool result.
  }

To render any json in tabular format:

<table>
    <thead>
      <tr>
        <th ng-repeat="(key, value) in vm.records[0]">{{key}}</th>
      </tr>
    </thead>
    <tbody>
      <tr ng-repeat="(key, value) in vm.records">
        <td ng-repeat="(key, value) in value">
          {{value}}
        </td>
      </tr>
    </tbody>
</table>

I believe the default color integer value is 16711935 (0x00FF00FF).

With lodash/underscore:

If you want to modify the existing array itself, then we have to use splice. Here is the little better/readable way using findWhere of underscore/lodash:

var items= [{id:'abc',name:'oh'}, // delete me
                  {id:'efg',name:'em'},
                  {id:'hij',name:'ge'}];

items.splice(_.indexOf(items, _.findWhere(items, { id : "abc"})), 1);

With ES5 or higher

(without lodash/underscore)

With ES5 onwards we have findIndex method on array, so its easier without lodash/underscore

items.splice(items.findIndex(function(i){
    return i.id === "abc";
}), 1);

(ES5 is supported in almost all morden browsers)

About findIndex, and its Browser compatibility

I recently was trying to do something similar. I decided I didn't like the sliding animation of the UINavigationController, but I also didn't want to do the animations that UIView gives you like curl or anything like that. I wanted to do a cross fade between the views when I push or pop.

The problem there involves the fact that the view is literally removing the view or popping one over the top of the current one, so a fade doesn't work. The solution I came to involved taking my new view and adding it as a subview to the current top view on the UIViewController's stack. I add it with an alpha of 0, then do a crossfade. When the animation sequence finishes, I push the view onto the stack without animating it. I then go back to the old topView and clean up stuff that I had changed.

Its a little more complicated than that, because you have the navigationItems you have to adjust to make the transition look correct. Also, if you do any rotation, you then have to adjust frame sizes as you add the views as subviews so they show up correctly on screen. Here is some of the code I used. I subclassed the UINavigationController and overrode the push and the pop methods.

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
      UIViewController *currentViewController = [self.viewControllers lastObject];
      //if we don't have a current controller, we just do a normal push
      if(currentViewController == nil)
      {
         [super pushViewController:viewController animated:animated];
         return;
      }
      //if no animation was requested, we can skip the cross fade
      if(!animation)
      {
         [super pushViewController:viewController animated:NO];
         return;
      }
      //start the cross fade.  This is a tricky thing.  We basically add the new view
//as a subview of the current view, and do a cross fade through alpha values.
//then we push the new view on the stack without animating it, so it seemlessly is there.
//Finally we remove the new view that was added as a subview to the current view.

viewController.view.alpha = 0.0;
//we need to hold onto this value, we'll be releasing it later
    NSString *title = [currentViewController.title retain];

//add the view as a subview of the current view
[currentViewController.view addSubview:viewController.view];
[currentViewController.view bringSubviewToFront:viewController.view];
UIBarButtonItem *rButtonItem = currentViewController.navigationItem.rightBarButtonItem;
UIBarButtonItem *lButtonItem = currentViewController.navigationItem.leftBarButtonItem;

NSArray *array = nil;

//if we have a right bar button, we need to add it to the array, if not, we will crash when we try and assign it
//so leave it out of the array we are creating to pass as the context.  I always have a left bar button, so I'm not checking to see if it is nil. Its a little sloppy, but you may want to be checking for the left BarButtonItem as well.
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,nil];
}

//remove the right bar button for our transition
[currentViewController.navigationItem setRightBarButtonItem:nil animated:YES];
//remove the left bar button and create a backbarbutton looking item
//[currentViewController.navigationItem setLeftBarButtonItem:nil animated:NO];

//set the back button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:title style:kButtonStyle target:self action:@selector(goBack)];
[currentViewController.navigationItem setLeftBarButtonItem:backButton animated:YES];
[viewController.navigationItem setLeftBarButtonItem:backButton animated:NO];
[backButton release];

[currentViewController setTitle:viewController.title];

[UIView beginAnimations:@"push view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePushDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[viewController.view setAlpha: 1.0];
[UIView commitAnimations];
}

-(void)animationForCrossFadePushDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{

UIViewController *c = [(NSArray*)context objectAtIndex:0];
UIViewController *n = [(NSArray*)context objectAtIndex:1];
NSString *title     = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:3];
UIBarButtonItem *r = nil;
//not all views have a right bar button, if we look for it and it isn't in the context,
//we'll crash out and not complete the method, but the program won't crash.
//So, we need to check if it is there and skip it if it isn't.
if([(NSArray *)context count] == 5)
    r = [(NSArray *)context objectAtIndex:4];

//Take the new view away from being a subview of the current view so when we go back to it
//it won't be there anymore.
[[[c.view subviews] lastObject] removeFromSuperview];
[c setTitle:title];
[title release];
//set the search button
[c.navigationItem setLeftBarButtonItem:l animated:NO];
//set the next button
if(r != nil)
    [c.navigationItem setRightBarButtonItem:r animated:NO];


[super pushViewController:n animated:NO];

 }

As I mention in the code, I always have a left bar button item, so I don't check to see if it is nil before putting it in the array that I pass as the context for the animation delegate. If you do this, you may want to make that check.

The problem I found was that if you crash at all in the delegate method, it won't crash the program. It just stops the delegate from completing but you don't get any kind of warning.
So since I was doing my cleanup in that delegate routine, it was causing some weird visual behavior since it wasn't finishing the cleanup.

The back button I create calls a "goBack" method, and that method just calls the pop routine.

-(void)goBack
{ 
     [self popViewControllerAnimated:YES];
}

Also, here is my pop routine.

-(UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    //get the count for the number of viewControllers on the stack
int viewCount = [[self viewControllers] count];
//get the top view controller on the stack
UIViewController *topViewController = [self.viewControllers objectAtIndex:viewCount - 1];
//get the next viewController after the top one (this will be the new top one)
UIViewController *newTopViewController = [self.viewControllers objectAtIndex:viewCount - 2];

//if no animation was requested, we can skip the cross fade
if(!animated)
{
    [super popViewControllerAnimated:NO];
            return topViewController;
}



//start of the cross fade pop.  A bit tricky.  We need to add the new top controller
//as a subview of the curent view controler with an alpha of 0.  We then do a cross fade.
//After that we pop the view controller off the stack without animating it.
//Then the cleanup happens: if the view that was popped is not released, then we
//need to remove the subview we added and change some titles back.
newTopViewController.view.alpha = 0.0;
[topViewController.view addSubview:newTopViewController.view];
[topViewController.view bringSubviewToFront:newTopViewController.view];
NSString *title = [topViewController.title retain];
UIBarButtonItem *lButtonItem = topViewController.navigationItem.leftBarButtonItem;
UIBarButtonItem *rButtonItem = topViewController.navigationItem.rightBarButtonItem;

//set the new buttons on top of the current controller from the new top controller
if(newTopViewController.navigationItem.leftBarButtonItem != nil)
{
    [topViewController.navigationItem setLeftBarButtonItem:newTopViewController.navigationItem.leftBarButtonItem animated:YES];
}
if(newTopViewController.navigationItem.rightBarButtonItem != nil)
{
    [topViewController.navigationItem setRightBarButtonItem:newTopViewController.navigationItem.rightBarButtonItem animated:YES];
}

[topViewController setTitle:newTopViewController.title];
//[topViewController.navigationItem.leftBarButtonItem setTitle:newTopViewController.navigationItem.leftBarButtonItem.title];

NSArray *array = nil;
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,nil];
}


[UIView beginAnimations:@"pop view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePopDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[newTopViewController.view setAlpha: 1.0];
[UIView commitAnimations];
return topViewController;

 }

 -(void)animationForCrossFadePopDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
 {

UIViewController *c = [(NSArray *)context objectAtIndex:0];
//UIViewController *n = [(NSArray *)context objectAtIndex:1];
NSString *title = [(NSArray *)context objectAtIndex:1];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *r = nil;



//Not all views have a right bar button.  If we look for one that isn't there
// we'll crash out and not complete this method, but the program will continue.
//So we need to check if it is therea nd skip it if it isn't.
if([(NSArray *)context count] == 4)
    r = [(NSArray *)context objectAtIndex:3];

//pop the current view from the stack without animation
[super popViewControllerAnimated:NO];

//if what was the current veiw controller is not nil, then lets correct the changes
//we made to it.
if(c != nil)
{
    //remove the subview we added for the transition
    [[c.view.subviews lastObject] removeFromSuperview];
    //reset the title we changed
    c.title = title;
    [title release];
    //replace the left bar button that we changed
    [c.navigationItem setLeftBarButtonItem:l animated:NO];
    //if we were passed a right bar button item, replace that one as well
    if(r != nil)
        [c.navigationItem setRightBarButtonItem:r animated:NO];
    else {
        [c.navigationItem setRightBarButtonItem:nil animated:NO];
    }


 }
}

That's pretty much it. You'll need some additional code if you want to implement rotations. You'll need to set the frame size of your views that you add as subviews before you show them otherwise you'll run into issues the orientation is landscape, but the last time you saw the previous view it was portrait. So, then you add it as a sub view and fade it in but it shows up as portrait, then when we pop without animation, the same view, but the one that is in the stack, now is landscape. The whole thing looks a little funky. Everyone's implementation of rotation is a little different so I didn't include my code for that here.

Hope it helps some people. I've looked all over for something like this and couldn't find anything. I don't think this is the perfect answer, but it is working real well for me at this point.

Sometimes you, also, need to clean this folder: C:\Windows\Temp\Temporary ASP.NET

You could use a StringReader and convert the reader to an input stream using the solution in this other stackoverflow post.

git rebase origin means "rebase from the tracking branch of origin", while git rebase origin/master means "rebase from the branch master of origin"

You must have a tracking branch in ~/Desktop/test, which means that git rebase origin knows which branch of origin to rebase with. If no tracking branch exists (in the case of ~/Desktop/fallstudie), git doesn't know which branch of origin it must take, and fails.

To fix this, you can make the branch track origin/master with:

git branch --set-upstream-to=origin/master 

Or, if master isn't the currently checked-out branch:

git branch --set-upstream-to=origin/master master

textarea {
  white-space: pre;
  overflow-wrap: normal;
  overflow-x: scroll;
}

white-space: nowrap also works if you don't care about whitespace, but of course you don't want that if you're working with code (or indented paragraphs or any content where there might deliberately be multiple spaces) ... so i prefer pre.

overflow-wrap: normal (was word-wrap in older browsers) is needed in case some parent has changed that setting; it can cause wrapping even if pre is set.

also -- contrary to the currently accepted answer -- textareas do often wrap by default. pre-wrap seems to be the default on my browser.

The Hashtable is a loosely-typed data structure, so you can add keys and values of any type to the Hashtable. The Dictionary class is a type-safe Hashtable implementation, and the keys and values are strongly typed. When creating a Dictionary instance, you must specify the data types for both the key and value.

Array.prototype.removeAt = function(id) {
    for (var item in this) {
        if (this[item].id == id) {
            this.splice(item, 1);
            return true;
        }
    }
    return false;
}

This should do the trick, jsfiddle

Use @ symbol before starting the string. like

string s = @"this is a really
long string
and this is 
the rest of it";

You Can Used This :

function ViewImage(){
 function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => resolve(reader.result);
    reader.onerror = error => reject(error);
  });
}
var file = document.querySelector('input[type="file"]').files[0];
getBase64(file).then(data =>$("#ImageBase46").val(data));
}

Add To Your Input onchange=ViewImage();

On the same theme as other answers, keeping it simple

Sub PrintArray(Data As Variant, Cl As Range)
    Cl.Resize(UBound(Data, 1), UBound(Data, 2)) = Data

@interface UIDevice (Screen)
typedef enum

@end

This way, if you want to detect whether it is just an iPhone or iPad (regardless of screen-size), you just use:

if ([UIDevice deviceType] & iPhone) 

or

if ([UIDevice deviceType] & iPad)

If you want to detect just the iPhone 5, you can use

if ([UIDevice deviceType] & iPhone5)

As opposed to Malcoms answer where you would need to check just to figure out if it's an iPhone,

if ([UIDevice currentResolution] == UIDevice_iPhoneHiRes || 
    [UIDevice currentResolution] == UIDevice_iPhoneStandardRes || 
    [UIDevice currentResolution] == UIDevice_iPhoneTallerHiRes)`

Neither way has a major advantage over one another, it is just a personal preference.

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

Neither one. Use final class for Constants declare them as public static final and static import all constants wherever necessary.

public final class Constants {

    private Constants() {
            // restrict instantiation
    }

    public static final double PI = 3.14159;
    public static final double PLANCK_CONSTANT = 6.62606896e-34;
}

Usage :

import static Constants.PLANCK_CONSTANT;
import static Constants.PI;//import static Constants.*;

public class Calculations {

        public double getReducedPlanckConstant() {
                return PLANCK_CONSTANT / (2 * PI);
        }
}

Chances are you are in the Python interpreter. Happens sometimes if you give this (Python) command in cmd.exe just to check the version of Python and you so happen to forget to come out.

angular 5 :

 getImage(id: string): Observable<Blob> {
    return this.httpClient.get('http://myip/image/'+id, {responseType: "blob"});
}

This can be achieved by the below code in Java 8 which has introduced a constructor which only takes a comparator.

PriorityQueue<Integer> maxPriorityQ = new PriorityQueue<Integer>(Collections.reverseOrder());

You may actually mean hovering the element by not clicking, right?

jQuery('#id').click(function()
{
    // execute on click
}).hover(function()
{
    // execute on hover
});

Clarify your question then we'll be able to understand better.

Simply if an element isn't being clicked on, do a setInterval to continue the process until clicked.

var checkClick = setInterval(function()
{
    // do something when the element hasn't been clicked yet
}, 2000); // every 2 seconds

jQuery('#id').click(function()
{
    clearInterval(checkClick); // this is optional, but it will
                               // clear the interval once the element
                               // has been clicked on

    // do something else
})

What about this one :

<DockPanel Margin="8">
    <Border CornerRadius="6" BorderBrush="Gray" Background="LightGray" BorderThickness="2" DockPanel.Dock="Top">
        <StackPanel Orientation="Horizontal">
            <TextBlock FontSize="14" Padding="0 0 8 0" HorizontalAlignment="Center" VerticalAlignment="Center">Search:</TextBlock>
            <TextBox x:Name="txtSearchTerm" HorizontalAlignment="Center" VerticalAlignment="Center" />
            <Image Source="lock.png" Width="32" Height="32" HorizontalAlignment="Center" VerticalAlignment="Center" />            
        </StackPanel>
    </Border>

An alternate solution that covers both min (1/1/1900) and max (6/6/2079) dates:

ISNULL(NULLIF(NULLIF(CONVERT(VARCHAR(10), CreatedDate, 120), '1900-01-01'), '2079-06-06'), '').

Whatever solution you use, you should do a conversion of your date (or datetime) field to a specific format to bulletproof against different default server configurations.

See CAST and CONVERT on MSDN: https://msdn.microsoft.com/en-us/library/ms187928.aspx

Also, you can use -o or --offline in the mvn command line which will put maven in "offline mode" so it won't check for updates. You'll get some warning about not being able to get dependencies not already in your local repo, but no big deal.

Deleting contents of folder C:\Users\User_Name\AppData\Roaming\pgAdmin\sessions helped me, I was able to start and load the pgAdmin server

You can use Environment.CurrentDirectory to get the current directory, and FileSystemInfo.FullPath to get the full path to any location. So, fully qualify both the current directory and the file in question, and then check whether the full file name starts with the directory name - if it does, just take the appropriate substring based on the directory name's length.

Here's some sample code:

using System;
using System.IO;

class Program
{
    public static void Main(string[] args)
    {
        string currentDir = Environment.CurrentDirectory;
        DirectoryInfo directory = new DirectoryInfo(currentDir);
        FileInfo file = new FileInfo(args[0]);

        string fullDirectory = directory.FullName;
        string fullFile = file.FullName;

        if (!fullFile.StartsWith(fullDirectory))
        {
            Console.WriteLine("Unable to make relative path");
        }
        else
        {
            // The +1 is to avoid the directory separator
            Console.WriteLine("Relative path: {0}",
                              fullFile.Substring(fullDirectory.Length+1));
        }
    }
}

I'm not saying it's the most robust thing in the world (symlinks could probably confuse it) but it's probably okay if this is just a tool you'll be using occasionally.

The currently selected solution produces incorrect results. To correctly solve this problem, we can perform a left-join from df1 to df2, making sure to first get just the unique rows for df2.

First, we need to modify the original DataFrame to add the row with data [3, 10].

df1 = pd.DataFrame(data = {'col1' : [1, 2, 3, 4, 5, 3], 
                           'col2' : [10, 11, 12, 13, 14, 10]}) 
df2 = pd.DataFrame(data = {'col1' : [1, 2, 3],
                           'col2' : [10, 11, 12]})

df1

   col1  col2
0     1    10
1     2    11
2     3    12
3     4    13
4     5    14
5     3    10

df2

   col1  col2
0     1    10
1     2    11
2     3    12

Perform a left-join, eliminating duplicates in df2 so that each row of df1 joins with exactly 1 row of df2. Use the parameter indicator to return an extra column indicating which table the row was from.

df_all = df1.merge(df2.drop_duplicates(), on=['col1','col2'], 
                   how='left', indicator=True)
df_all

   col1  col2     _merge
0     1    10       both
1     2    11       both
2     3    12       both
3     4    13  left_only
4     5    14  left_only
5     3    10  left_only

Create a boolean condition:

df_all['_merge'] == 'left_only'

0    False
1    False
2    False
3     True
4     True
5     True
Name: _merge, dtype: bool

Why other solutions are wrong

A few solutions make the same mistake - they only check that each value is independently in each column, not together in the same row. Adding the last row, which is unique but has the values from both columns from df2 exposes the mistake:

common = df1.merge(df2,on=['col1','col2'])
(~df1.col1.isin(common.col1))&(~df1.col2.isin(common.col2))
0    False
1    False
2    False
3     True
4     True
5    False
dtype: bool

This solution gets the same wrong result:

df1.isin(df2.to_dict('l')).all(1)

I cannot solve it with source ./myscript.sh. It says the source not found error.
Failed also when using . ./myscript.sh. It gives can't open myscript.sh.

So my option is put it in a text file to be called in the next script.

#!/bin/sh
echo "Perform Operation in su mode"
echo "ARCH=arm" >> environment.txt
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export "CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?" >> environment.txt
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...

Tnen call it whenever is needed:

while read -r line; do
    line=$(sed -e 's/[[:space:]]*$//' <<<${line})
    var=`echo $line | cut -d '=' -f1`; test=$(echo $var)
    if [ -z "$(test)" ];then eval export "$line";fi
done <environment.txt

According to the Java docs, it looks like you need to use the MemoryImageSource Class to put your byte array into an object in memory, and then use Component.createImage(ImageProducer) next (passing in your MemoryImageSource, which implements ImageProducer).

There are multiple solutions for this. If you want the page to be refreshed you actually don't need JavaScript, the browser can do it for you if you add this meta tag in your head tag.

<meta http-equiv="refresh" content="30">

The browser will then refresh the page every 30 seconds.

If you really want to do it with JavaScript, then you can refresh the page every 30 seconds with location.reload() (docs) inside a setTimeout():

window.setTimeout(function () {
  window.location.reload();
}, 30000);

If you don't need to refresh the whole page but only a part of it, I guess an Ajax call would be the most efficient way.

If i understand what you want:

'email' => 'required|email|unique:users,email_address,'. $id .''

In model update method, for exemple, should receive the $id with parameter.

Sorry my bad english.

The DOM interface, already keeps track of the initial state...

So doing the following is enough:

$("#reset").on("click", function () {
    $('#my_select option').prop('selected', function() {
        return this.defaultSelected;
    });
});

I think you need OpenSessionInViewFilter to keep your session open during view rendering (but it is not too good practice).

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

    JsonParser parser = new JsonParser();
    JsonObject jo = (JsonObject) parser.parse(data);
    JsonElement je = jo.get("some_array");

    //Parsing back the string as Array
    JsonArray ja = (JsonArray) parser.parse(o.get("some_array").getAsString());
    for (JsonElement jo : ja) {
    JsonObject j = (JsonObject) jo;
        // Your Code, Access json elements as j.get("some_element")
    }

A simple example to parse a JSON like this

{ "some_array" : "[\"some_element\":1,\"some_more_element\":2]" , "some_other_element" : 3 }

Note: this doesn't exactly address the OP's original, 7 year old problem but should help some noob linux users (like me) who find their way here from the SE's with similar "how do I get my text all on one line" questions.

The accepted answer didn't work with my form, even when I stripped it down to the bare minimum and copied & pasted the code. If anyone else is having this problem, please give my solution a try. Basically, you set Top and Left to 50% as the OP did, but offset the form's container with negative margins on the top and left equal to 50% of the div's height and width, respectively. This moves the center point of the Top and Left coordinates to the center of the form. I will stress that the height and width of the form must be specified (not relative). In this example, a 300x300px form div with margins of -150px on the top and left is perfectly centered no matter the window size:

HTML

<body>
    <div class="login_div">
        <form class="login_form" action="#">
        </form>
    </div>
</body>

CSS

.login_div {
    position: absolute;

    width: 300px;
    height: 300px;

    /* Center form on page horizontally & vertically */
    top: 50%;
    left: 50%;
    margin-top: -150px;
    margin-left: -150px;
}

.login_form {
    width: 300px;
    height: 300px;

    background: gray;
    border-radius: 10px;

    margin: 0;
    padding: 0;
}

JSFiddle

Now, for those wondering why I used a container for the form, it's because I like to have the option of placing other elements in the form's vicinity and having them centered as well. The form container is completely unnecessary in this example, but would definitely be useful in other cases. Hope this helps!

SELECT * FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

Update : for better performance and faster query its good to add e1 before *

SELECT e1.* FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

Use

System.getProperty("java.class.path")

see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

You can also split it into it's elements easily

String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);

This is probably obvious, but simplest:

You can download the required files from the Microsoft website or online or reinstall the Visual studio 2012 to fix this.

You don't need to override onBackPressed() - it's already defined as the action that your activity will do by default when the user pressed the back button. So just call onBackPressed() whenever you want to "programatically press" the back button.

That would only result to finish() being called, though ;)

I think you're confused with what the back button does. By default, it's just a call to finish(), so it just exits the current activity. If you have something behind that activity, that screen will show.

What you can do is when launching your activity from the Login, add a CLEAR_TOP flag so the login activity won't be there when you exit yours.

This works i tried it my self i thought i post it here in case someone need it...

document.getElementById("newSkill").options[document.getElementById('newSkill').selectedIndex].text;

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request
resp2 = requests.get(secondUrl, cookies= resp1.cookies)

resp3 = requests.get(thirdUrl, cookies= resp2.cookies)

Consider the partial map.cshtml at Partials/Map.cshtml. This can be called from the Page where the partial is to be rendered, simply by using the <partial> tag:

<partial name="Partials/Map" model="new Pages.Partials.MapModel()" />

This is one of the easiest methods I encountered (although I am using razor pages, I am sure same is for MVC too)

To update the record by trimming the last N characters of a particular column:

UPDATE tablename SET columnName = LEFT(columnName , LEN(columnName )-N) where clause

i would see a very simple way

git reset --hard HEAD <YOUR COMMIT ID>

and then reset remote branch

git push origin -f

My first contribution to the community , example as rotating a simple text and the header of a table, only using html and css.

HTML

<div class="rotate">text</div>

CSS

.rotate {
  display:inline-block;
  filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);
  -webkit-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  transform: rotate(270deg);
}

Here an example in jsfiddle

The title of this thread asks how a subquery can be used in an update. Here's an example of that:

update [dbName].[dbo].[MyTable] 
set MyColumn = 1 
where 
    (
        select count(*) 
        from [dbName].[dbo].[MyTable] mt2 
        where
            mt2.ID > [dbName].[dbo].[MyTable].ID
            and mt2.Category = [dbName].[dbo].[MyTable].Category
    ) > 0

.hide() stores the previous display property just before setting it to none, so if it wasn't the standard display property for the element you're a bit safer, .show() will use that stored property as what to go back to. So...it does some extra work, but unless you're doing tons of elements, the speed difference should be negligible.

I am using Debian 8 live off a USB. I was locked out of the system after 10 min of inactivity. The password that was required to log back in to the system for the user was:

login : Debian Live User
password : live

I hope this helps

Good question. These two operators work the same in PHP and C#.

| is a bitwise OR. It will compare two values by their bits. E.g. 1101 | 0010 = 1111. This is extremely useful when using bit options. E.g. Read = 01 (0X01) Write = 10 (0X02) Read-Write = 11 (0X03). One useful example would be opening files. A simple example would be:

File.Open(FileAccess.Read | FileAccess.Write);  //Gives read/write access to the file

|| is a logical OR. This is the way most people think of OR and compares two values based on their truth. E.g. I am going to the store or I will go to the mall. This is the one used most often in code. For example:

if(Name == "Admin" || Name == "Developer") { //allow access } //checks if name equals Admin OR Name equals Developer
