In my case, I was trying to use mdbreact on windows. Though it installed, But i was getting the above error. I had to reinstall it and everything was ok. It happened to me once two with antd Library

You want an independent for loop for all the rows in grid view, then refer the below link

http://nikhilsreeni.wordpress.com/asp-net/checkbox/

Select all checkbox in Gridview

CheckBox cb = default(CheckBox);
for (int i = 0; i <= grdforumcomments.Rows.Count – 1; i++)
{
    cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);

    cb.Checked = ((CheckBox)sender).Checked;
}

Select checked rows to a dataset; For gridview multiple edit

CheckBox cb = default(CheckBox);

foreach (GridViewRow row in grdforumcomments.Rows)
{
    cb = (CheckBox)row.FindControl("cbsel");
    if (cb.Checked)
    {
        drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
        drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;
        drArticleCommentsUpdates["Date"] = System.DateTime.Now;dtArticleCommentsUpdates.Rows.Add(drArticleCommentsUpdates);
    }
}

In my project i am using ajax and i create a web method in my code behind like this

in front

 $("#attachedfiles a").live("click", function () {
            var row = $(this).closest("tr");
            var fileName = $("td", row).eq(0).html();
            $.ajax({
                type: "POST",
                url: "SendEmail.aspx/RemoveFile",
                data: '{fileName: "' + fileName + '" }',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function () { },
                failure: function (response) {
                    alert(response.d);
                }
            });
            row.remove();
        });  

in code behind

        [WebMethod]
        public static void RemoveFile(string fileName)
        {
            List<HttpPostedFile> files = (List<HttpPostedFile>)HttpContext.Current.Session["Files"];
            files.RemoveAll(f => f.FileName.ToLower().EndsWith(fileName.ToLower()));

            if (System.IO.File.Exists(HttpContext.Current.Server.MapPath("~/Employee/uploads/" + fileName)))
            {
                System.IO.File.Delete(HttpContext.Current.Server.MapPath("~/Employee/uploads/" + fileName));
            }
        }

i think this will help you.

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

$content = '';
    for($rowth=0; $rowth<=100; $rowth++){
        $content .= $selenium->getTable("tblReports.{$rowth}.0") . "\n";
        //$content .= $selenium->getTable("tblReports.{$rowth}.1") . "\n";
        $content .= $selenium->getTable("tblReports.{$rowth}.2") . " ";
        $content .= $selenium->getTable("tblReports.{$rowth}.3") . " ";
        $content .= $selenium->getTable("tblReports.{$rowth}.4") . " ";
        $content .= $selenium->getTable("tblReports.{$rowth}.5") . " ";
        $content .= $selenium->getTable("tblReports.{$rowth}.6") . "\n";

    }

Resumee of Richard Fearn's answer , to make each second line gray:

jTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer()
{
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
    {
        final Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        c.setBackground(row % 2 == 0 ? Color.LIGHT_GRAY : Color.WHITE);
        return c;
    }
});

Multi-line buttons like that are not really trivial to implement. This page has an interesting (though somewhat dated) discussion on the subject. Your best bet would probably be to either drop the multi-line requirement or to create a custom button using e.g. divs and CSS, and adding some JavaScript to make it work as a button.

Edit: Here's a plugin I authored that extends the jQuery UI Dialog to include closing when clicking outside plus other features: https://github.com/jasonday/jQuery-UI-Dialog-extended

Here are 3 methods to close a jquery UI dialog when clicking outside popin:

If the dialog is modal/has background overlay: http://jsfiddle.net/jasonday/6FGqN/

jQuery(document).ready(function() {
    jQuery("#dialog").dialog({
        bgiframe: true,
        autoOpen: false,
        height: 100,
        modal: true,
        open: function() {
            jQuery('.ui-widget-overlay').bind('click', function() {
                jQuery('#dialog').dialog('close');
            })
        }
    });
}); 

If dialog is non-modal Method 1: http://jsfiddle.net/jasonday/xpkFf/

// Close Pop-in If the user clicks anywhere else on the page
jQuery('body')
    .bind('click', function(e) {
        if(jQuery('#dialog').dialog('isOpen')
            && !jQuery(e.target).is('.ui-dialog, a')
            && !jQuery(e.target).closest('.ui-dialog').length
        ) {
            jQuery('#dialog').dialog('close');
        }
    });

Non-Modal dialog Method 2: http://jsfiddle.net/jasonday/eccKr/

$(function() {
    $('#dialog').dialog({
        autoOpen: false, 
        minHeight: 100,
        width: 342,
        draggable: true,
        resizable: false,
        modal: false,
        closeText: 'Close',
        open: function() {
            closedialog = 1;
            $(document).bind('click', overlayclickclose); },
        focus: function() { 
            closedialog = 0; },
        close: function() { 
            $(document).unbind('click'); }
    });

    $('#linkID').click(function() {
        $('#dialog').dialog('open');
        closedialog = 0;
    });

    var closedialog;

    function overlayclickclose() {
        if (closedialog) {
            $('#dialog').dialog('close');
        }
        //set to one because click on dialog box sets to zero
        closedialog = 1;
    }
});

To stop your loop you can use break with label. It will stop your loop for sure. Code is written in Java but aproach is the same for the all languages.

public void exitFromTheLoop() {
    boolean value = true;
            loop_label:for (int i = 0; i < 10; i++) {
              if(!value) { 
                 System.out.println("iteration: " + i);
              break loop_label;
        }
    }
}   

}

See the MSDN reference table for maximum numbers/sizes.

Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1

There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)

I had to use a HTTP connection, because on HTTPS there is default file size limit.

https://techcommunity.microsoft.com/t5/IIS-Support-Blog/Solution-for-Request-Entity-Too-Large-error/ba-p/501134

    curl -i -X 'POST' -F 'file=@/home/testeincremental.xlsx' 'http://example.com/upload.aspx?user=example&password=example123&type=XLSX'

I like the short version on top of @The lorax, but for other language settings it might be slightly different.

For example, in german language settings (with natural date format: dd.mm.yyyy) the month query has to be altered from 4,2 to 3,2:

@ECHO OFF
: Sets the proper date and time stamp with 24h time for log file naming convention i.e.

SET HOUR=%time:~0,2%
SET dtStamp9=%date:~-4%%date:~3,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2% 
SET dtStamp24=%date:~-4%%date:~3,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%

if "%HOUR:~0,1%" == " " (SET dtStamp=%dtStamp9%) else (SET dtStamp=%dtStamp24%)

ECHO %dtStamp%
: Outputs= 20160727_081040
: (format: YYYYMMDD_HHmmss; e.g.: the date-output of this post timestamp)

Use Google Search Operators to find it for you

search google with the below code..

inurl:domain.com filetype:xml click on this to view sitemap search example

change domain.com to the domain you want to find the sitemap. this should list all the xml files listed for the given domain.. including all sitemaps :)

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

More info: https://github.com/fchollet/keras/issues/2524

You might need to run it via cmd, eg:

system("cmd /c C:[path to file]");

If you need to hit the database, you need to hit the web server again (for the most part).

What you can do is use AJAX, which makes a request to another script on your site to retrieve data, gets the data, and then updates the input fields you want.

AJAX calls can be made in jquery with the $.ajax() function call, so this will happen

User's browser enters input that fires a trigger that makes an AJAX call

$('input .callAjax').bind('change', function() { 
  $.ajax({ url: 'script/ajax', 
           type: json
           data: $foo,  
           success: function(data) {
             $('input .targetAjax').val(data.newValue);
           });
  );

Now you will need to point that AJAX call at script (sounds like you're working PHP) that will do the query you want and send back data.

You will probably want to use the JSON object call so you can pass back a javascript object, that will be easier to use than return XML etc.

The php function json_encode($phpobj); will be useful.

import java.util.Scanner;

public class LargestSmallestNumbers {

    private static Scanner input;

    public static void main(String[] args) {
       int count,items;
       int newnum =0 ;
       int highest=0;
       int lowest =0;

       input = new Scanner(System.in);
       System.out.println("How many numbers you want to enter?");
       items = input.nextInt();

       System.out.println("Enter "+items+" numbers: ");


       for (count=0; count<items; count++){
           newnum = input.nextInt();               
           if (highest<newnum)
               highest=newnum;

           if (lowest==0)
               lowest=newnum;

           else if (newnum<=lowest)
               lowest=newnum;
           }

       System.out.println("The highest number is "+highest);
       System.out.println("The lowest number is "+lowest);
    }
}

I prefer to use <limits> to check for an int until it is passed.

#include <iostream>
#include <limits> //std::numeric_limits

using std::cout, std::endl, std::cin;

int main() {
    int num;
    while(!(cin >> num)){  //check the Input format for integer the right way
        cin.clear();
        cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        cout << "Invalid input.  Reenter the number: ";
      };

    cout << "output= " << num << endl;

    return 0;
}

You can choose only install the client during server install. The website only offers to let you download the full installer (grab whatever version you want from http://www.mysql.com/downloads/mysql/).

In the install wizard, when prompted for installation type (typical, minimal, custom), choose 'Custom'. On the next screen, select to NOT install the server, and proceed with the rest of the install as normal.

When you're done, you should see just the relevant client programs (mysql, mysqldump, etc) in C:\Program Files\MySQL..\bin

I had the same issue and in the end It turned out that I just had to restart the server and start again

Ctrl + c then

php artisan serve

You can try using:

textBox.ReadOnly = true;
textBox.BackColor = System.Drawing.SystemColors.Window;

The last line is only neccessary if you want a non-grey background color.

The general practice is to have the central repository to which you push as a bare repo.

If you have SVN background, you can relate an SVN repo to a Git bare repo. It doesn't have the files in the repo in the original form. Whereas your local repo will have the files that form your "code" in addition.

You need to add a remote to the bare repo from your local repo and push your "code" to it.

It will be something like:

git remote add central <url> # url will be ssh based for you
git push --all central

I had the same problem and in my case the problem was missing and/or incorrect equals implementation on some types of fields in the entity object. At commit time, Hibernate checks ALL entities loaded in the session to check if they are dirty. If any of the entities are dirty, hibernate tries to persist them - no matter of the fact that the actual object that is requested a save operation is not related to the other entities.

Entity dirtiness is done by comparing every property of given object (with their equals methods) or UserType.equals if property has an associated org.Hibernate.UserType.

Another thing that surprised me was, in my transaction (using Spring annotation @Transactional), I was dealing with a single entity. Hibernate was complaining about some random entity that's unrelated to that entity being saved. What I realized is there is an outermost transaction we create at REST controller level, so the scope of the session is too big and hence all objects ever loaded as part of request processing get checked for dirtiness.

Hope this helps someone, some day.

Thanks Rags

I imported the project as general project from git repository.

• Deleted .settings, .project and .classpath in project's folder
• Configure -> Convert to Maven Project. Only this solved the problem in my case.

It's safe to just delete the source directory and compiled package file. Find the source directory under $GOPATH/src and the package file under $GOPATH/pkg/<architecture>, for example: $GOPATH/pkg/windows_amd64.

>>> A = np.random.randint(5, size=(10,3))
>>> A
array([[1, 3, 0],
       [3, 2, 0],
       [0, 2, 1],
       [1, 1, 4],
       [3, 2, 2],
       [0, 1, 0],
       [1, 3, 1],
       [0, 4, 1],
       [2, 4, 2],
       [3, 3, 1]])
>>> idx = np.random.randint(10, size=2)
>>> idx
array([7, 6])
>>> A[idx,:]
array([[0, 4, 1],
       [1, 3, 1]])

Putting it together for a general case:

A[np.random.randint(A.shape[0], size=2), :]

For non replacement (numpy 1.7.0+):

A[np.random.choice(A.shape[0], 2, replace=False), :]

I do not believe there is a good way to generate random list without replacement before 1.7. Perhaps you can setup a small definition that ensures the two values are not the same.

I do it a little different from Mark. I pass the entire domain and grab the subdomain in php.

RewriteCond {REQUEST_URI} !\.(png|gif|jpg)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?uri=$1&hostName=%{HTTP_HOST}

This ignores images and maps everything else to my index.php file. So if I go to

http://fred.mywebsite.com/album/Dance/now

I get back

http://fred.mywebsite.com/index.php?uri=album/Dance/now&hostName=fred.mywebsite.com

Then in my index.php code i just explode my username off of the hostName. This gives me nice pretty SEO URLs.

If U want commit to a new empty Repo ,You can checkout the new empty Repo and commit to new remote repo.
chekout a new empty Repo won't delete your local files.
try this: for example, remote repo url : https://example.com/SVNTest cd [YOUR PROJECT PATH] rm -rf .svn svn co https://example.com/SVNTest ../[YOUR PROJECT DIR NAME] svn add ./* svn ci -m"changed repo url"

Depending on what browsers you're targeting, you could go for the object-fit property to solve this:

object-fit: cover;

or maybe fill is what you're looking for. Still under consideration for IE.

Try using the ToDictionary method like so:

var dict = TableObj.ToDictionary( t => t.Key, t => t.TimeStamp );

Adding my answer as this is the top result on Google for this.

I'm using Visual Studio 2015 and (unknowingly - I just ran Install-Package NUnit) installed the NUnit3 package NuGet to my test project. I already had the NUnit Test Adapter extension installed, and my tests were still not showing up.

Installing the NUnit3 Test Adapter through Tools > Extensions and Updates fixed this for me.

WordPad will open any text file no matter the size. However, it has limited capabilities as compared to a text editor.

The shift can be implement with data types (char, int and long int). The float and double data connot be shifted.

value= value >> steps  // Right shift, signed data.
value= value << steps  // Left shift, signed data.

The main difference is that WHERE cannot be used on grouped item (such as SUM(number)) whereas HAVING can.

The reason is the WHERE is done before the grouping and HAVING is done after the grouping is done.

How can I get the value from the map, which is passed as a reference to a function?

Well, you can pass it as a reference. The standard reference wrapper that is.

typedef std::map<std::string, std::string> MAP;
// create your map reference type
using map_ref_t = std::reference_wrapper<MAP>;

// use it 
void function(map_ref_t map_r)
{
    // get to the map from inside the
    // std::reference_wrapper
    // see the alternatives behind that link
    MAP & the_map = map_r;
    // take the value from the map
    // by reference
    auto & value_r = the_map["key"];
    // change it, "in place"
    value_r = "new!";
}

And the test.

    void test_ref_to_map() {

    MAP valueMap;
    valueMap["key"] = "value";
    // pass it by reference
    function(valueMap);
    // check that the value has changed
    assert( "new!" == valueMap["key"] );
}

I think this is nice and simple. Enjoy ...

Yes, you can use the shorthand syntax for if statements.

rate = lambda(t): (200 * exp(-t)) if t > 200 else (400 * exp(-t))

Note that you don't use explicit return statements inlambdas either.

Do note that PostgreSQL 9.0 (today in beta testing) will have a simple way to do that:

test=> GRANT SELECT ON ALL TABLES IN SCHEMA public TO joeuser;

Global libraries

You can run npm list -g to see which global libraries are installed and where they're located. Use npm list -g | head -1 for truncated output showing just the path. If you want to display only main packages not its sub-packages which installs along with it - you can use - npm list --depth=0 which will show all packages and for getting only globally installed packages, just add -g i.e. npm list -g --depth=0.

On Unix systems they are normally placed in /usr/local/lib/node or /usr/local/lib/node_modules when installed globally. If you set the NODE_PATH environment variable to this path, the modules can be found by node.

Windows XP - %USERPROFILE%\AppData\npm\node_modules
Windows 7, 8 and 10 - %USERPROFILE%\AppData\Roaming\npm\node_modules

Non-global libraries

Non-global libraries are installed the node_modules sub folder in the folder you are currently in.

You can run npm list to see the installed non-global libraries for your current location.

When installing use -g option to install globally

npm install -g pm2 - pm2 will be installed globally. It will then typically be found in /usr/local/lib/node_modules (Use npm root -g to check where.)

npm install pm2 - pm2 will be installed locally. It will then typically be found in the local directory in /node_modules

Try the following:

var div = document.createElement("div");
div.innerHTML = "topdiv";
div.appendChild(element);
document.body.appendChild(div);

I wrote the following code in one of my projects. It basically compares each individual element of the list. Feel free to use it, if it works for your requirement.

def reachedGoal(a,b):
    if(len(a)!=len(b)):
        raise ValueError("Wrong lists provided")

    for val1 in range(0,len(a)):
        temp1=a[val1]
        temp2=b[val1]
        for val2 in range(0,len(b)):
            if(temp1[val2]!=temp2[val2]):
                return False
    return True

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null or undefined here, so don't complain about the possibility of it being null or undefined." Sometimes the type checker is unable to make that determination itself.

It is explained here:

A new ! post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operation x! produces a value of the type of x with null and undefined excluded. Similar to type assertions of the forms <T>x and x as T, the ! non-null assertion operator is simply removed in the emitted JavaScript code.

I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.

A bit old, but oh well...

The most up-voted solution from @houbysoft will not work as that will exclude any line with "gloom" in it, even if it has "loom". According to OP's expectations, we need to include lines with "loom", even if they also have "gloom" in them. This line needs to be in the output "Arty is slooming in a gloomy day.", but this will be excluded by a chained grep like

grep -n 'loom' ~/projects/**/trunk/src/**/*.@(h|cpp) | grep -v 'gloom'

Instead, the egrep regex example of Bentoy13 works better

egrep '(^|[^g])loom' ~/projects/**/trunk/src/**/*.@(h|cpp)

as it will include any line with "loom" in it, regardless of whether or not it has "gloom". On the other hand, if it only has gloom, it will not include it, which is precisely the behaviour OP wants.

At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref or reftype is a bad idea. I don't recall who put the idea forward, or the link. Sorry.

The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie a filehandle so that it acts like a hash, the testing with reftype will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.

So, the argument went, it is better to use duck typing to find out what a variable is.

Instead of:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;
    if( $type eq 'HASH' ) {
        $result = $var->{foo};
    }
    elsif( $type eq 'ARRAY' ) {
        $result = $var->[3];
    }
    else {
        $result = 'foo';
    }

    return $result;
}

You should do something like this:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;

    eval {
        $result = $var->{foo};
        1; # guarantee a true result if code works.
    }
    or eval { 
        $result = $var->[3];
        1;
    }
    or do {
        $result = 'foo';
    }

    return $result;
}

For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.

Update

I realized I should put forward my thoughts on this approach.

This method has the advantage of handling anything you throw at it.

It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.

I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.

I don't like this implementation.

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

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

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

See also:

• ViewParam vs @ManagedProperty(value = "#{param.id}")
• Communication in JSF 2.0 - Processing GET request parameters

A CustomValidator would also work here:

<asp:CustomValidator runat="server"
    ID="valDateRange" 
    ControlToValidate="txtDatecompleted"
    onservervalidate="valDateRange_ServerValidate" 
    ErrorMessage="enter valid date" />

Code-behind:

protected void valDateRange_ServerValidate(object source, ServerValidateEventArgs args)
{
    DateTime minDate = DateTime.Parse("1000/12/28");
    DateTime maxDate = DateTime.Parse("9999/12/28");
    DateTime dt;

    args.IsValid = (DateTime.TryParse(args.Value, out dt) 
                    && dt <= maxDate 
                    && dt >= minDate);
}

SELECT t.*,(select count(*) from city as tt where tt.name=t.name) as count FROM `city` as t where (select count(*) from city as tt where tt.name=t.name) > 1 order by count desc

Replace city with your Table. Replace name with your field name

you can use this syntax:

INSERT INTO table_name ( name, age )
select  'jonny', 18 from dual
where not exists(select 1 from table_name where name = 'jonny');

if its open an pop for asking as "enter substitution variable" then use this before the above queries:

set define off;
INSERT INTO table_name ( name, age )
select  'jonny', 18 from dual
where not exists(select 1 from table_name where name = 'jonny');

Use Subscript Generating Functions.
http://www.postgresql.org/docs/current/static/functions-srf.html#FUNCTIONS-SRF-SUBSCRIPTS

For example:

SELECT 
  id
  , elements[i] AS elem
  , i AS nr
FROM
  ( SELECT 
      id
      , elements
      , generate_subscripts(elements, 1) AS i
    FROM
      ( SELECT
          id
          , string_to_array(elements, ',') AS elements
        FROM
          myTable
      ) AS foo
  ) bar
;

More simply:

SELECT
  id
  , unnest(elements) AS elem
  , generate_subscripts(elements, 1) AS nr
FROM
  ( SELECT
      id
      , string_to_array(elements, ',') AS elements
    FROM
      myTable
  ) AS foo
;

You can trigger a download with the HTML5 download attribute.

<a href="path_to_file" download="proposed_file_name">Download</a>

Where:

• path_to_file is a path that resolves to an URL on the same origin. That means the page and the file must share the same domain, subdomain, protocol (HTTP vs. HTTPS), and port (if specified). Exceptions are blob: and data: (which always work), and file: (which never works).
• proposed_file_name is the filename to save to. If it is blank, the browser defaults to the file's name.

Here is a callback object I wrote where you can either set a single callback to fire once all complete or let each have their own callback and fire them all once all complete:

NOTICE

Since jQuery 1.5+ you can use the deferred method as described in another answer:

  $.when($.ajax(), [...]).then(function(results){},[...]);

Example of deferred here

for jQuery < 1.5 the following will work or if you need to have your ajax calls fired at unknown times as shown here with two buttons: fired after both buttons are clicked

[usage]

for single callback once complete: Working Example

// initialize here
var requestCallback = new MyRequestsCompleted({
    numRequest: 3,
    singleCallback: function(){
        alert( "I'm the callback");
    }
});

//usage in request
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.requestComplete(true);
    }
});
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.requestComplete(true);
    }
});
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.requestComplete(true);
    }
});

each having their own callback when all complete: Working Example

//initialize 
var requestCallback = new MyRequestsCompleted({
    numRequest: 3
});

//usage in request
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.addCallbackToQueue(true, function() {
            alert('Im the first callback');
        });
    }
});
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.addCallbackToQueue(true, function() {
            alert('Im the second callback');
        });
    }
});
$.ajax({
    url: '/echo/html/',
    success: function(data) {
        requestCallback.addCallbackToQueue(true, function() {
            alert('Im the third callback');
        });
    }
});

[The Code]

var MyRequestsCompleted = (function() {
    var numRequestToComplete, requestsCompleted, callBacks, singleCallBack;

    return function(options) {
        if (!options) options = {};

        numRequestToComplete = options.numRequest || 0;
        requestsCompleted = options.requestsCompleted || 0;
        callBacks = [];
        var fireCallbacks = function() {
            alert("we're all complete");
            for (var i = 0; i < callBacks.length; i++) callBacks[i]();
        };
        if (options.singleCallback) callBacks.push(options.singleCallback);

        this.addCallbackToQueue = function(isComplete, callback) {
            if (isComplete) requestsCompleted++;
            if (callback) callBacks.push(callback);
            if (requestsCompleted == numRequestToComplete) fireCallbacks();
        };
        this.requestComplete = function(isComplete) {
            if (isComplete) requestsCompleted++;
            if (requestsCompleted == numRequestToComplete) fireCallbacks();
        };
        this.setCallback = function(callback) {
            callBacks.push(callBack);
        };
    };
})();

For that particular case you can use:

.detail_container > ul + h1{ 
    color: blue; 
}

But if you need that same selector on many cases, you should have a class for those, like BoltClock said.

Late to the party, but for posterity, the stringr package (part of the popular "tidyverse" suite of packages) now provides functions with harmonised signatures for string handling:

string <- c("G1:E001", "G2:E002", "G3:E003")
# match string to keep
stringr::str_extract(string = string, pattern = "E[0-9]+")
# [1] "E001" "E002" "E003"

# replace leading string with ""
stringr::str_remove(string = string, pattern = "^.*:")
# [1] "E001" "E002" "E003"

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

From the docs, "Note that from + size can not be more than the index.max_result_window index setting which defaults to 10,000". So my admittedly very ad-hoc solution is to just pass size: 10000 or 10,000 minus from if I use the from argument.

Note that following Matt's comment below, the proper way to do this if you have a larger amount of documents is to use the scroll api. I have used this successfully, but only with the python interface.

Even though I had gcc already installed, I had to run

sudo apt-get install build-essential

to get rid of that error

For swift

var label = UILabel(frame: CGRect(x: 0, y: 0, width: 250, height: 50))
label.textAlignment = .left
label.text = "This is a Label"
self.view.addSubview(label)

based on OP's answer to question:

Please see this link. Its having a different solution, which looks working for the person who asked the question. I'm trying to figure out a solution like this.

Be aware that there is org.codehaus.jackson.annotate.JsonProperty in Jackson 1.x and com.fasterxml.jackson.annotation.JsonProperty in Jackson 2.x. Check which ObjectMapper you are using (from which version), and make sure you use the proper annotation.

A great way to automatically generate these classes for you is to copy your JSON output and throw it in here:

http://json2csharp.com/

It will provide you with a starting point to touch up your classes for deserialization.

I want to enhance Mr. Kamran Ali's answer with pictorial view.

Pictorial View is given step by step:

1. Go to "Database" Menu option
2. Select the "Reverse Engineer" option.

3. A wizard will come. Select from "Stored Connection" and press "Next" button.

4. Then "Next"..to.."Finish"

Enjoy :)

In my case the reason was some wrong certificate that could not be loaded. I found out about it from the Event Viewer, under System:

A fatal error occurred when attempting to access the TLS server credential private key. The error code returned from the cryptographic module is 0x8009030D. The internal error state is 10001.

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

To install GLIBC_2.14 or GLIBC_2.15, download package from /gnu/libc/ index at

https://ftp.gnu.org/gnu/libc/

Then follow instructions listed by Timo:

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz

2. cd glibc-2.14

3. mkdir build

4. cd build

5. ../configure --prefix=/opt/glibc-2.14

6. make

7. sudo make install

8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

The solution is very simple if we consider the type of the constant value, which should be "unsigned int" instead of "int".

Instead of:

setval(0)

Use:

setval(0u)

The suffix "u" tell the compiler this is a unsigned integer. Then, no conversion would be needed, and the call will be unambiguous.

You can also do something like this...

<input @input="myHandler('foo', 'bar', ...arguments)">

Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.

With SimpleDateFormat. And steps are -

1. Create your date pattern string
2. Create SimpleDateFormat Object
3. And parse with it.
4. It will return Date Object.

The main difference is that sorted(some_list) returns a new list:

a = [3, 2, 1]
print sorted(a) # new list
print a         # is not modified

and some_list.sort(), sorts the list in place:

a = [3, 2, 1]
print a.sort() # in place
print a         # it's modified

Note that since a.sort() doesn't return anything, print a.sort() will print None.

Can a list original positions be retrieved after list.sort()?

No, because it modifies the original list.

You can add script tags in your HTML document, ideally inside the which points to your javascript files. Order of the script tags are important. Load the jQuery before your script files if you want to use jQuery from your script.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="relative/path/to/your/javascript.js"></script>

Then in your javascript file you can refer to jQuery either using $ sign or jQuery. Example:

jQuery.each(arr, function(i) { console.log(i); }); 

You need to pass it as an extra:

String easyPuzzle  = "630208010200050089109060030"+
                     "008006050000187000060500900"+

Intent i = new Intent(this, ToClass.class);
i.putExtra("epuzzle", easyPuzzle);
startActivity(i); 

Then extract it from your new activity like this:

Intent intent = getIntent();
String easyPuzzle = intent.getExtras().getString("epuzzle");

For me, the try_files directive in the (currently most voted) answer https://stackoverflow.com/a/11957896/608359 led to rewrite cycles,

*173 rewrite or internal redirection cycle while internally redirecting

I had better luck with the index directive. Note that I used a forward slash before the name, which might or might not be what you want.

server {
  listen 443 ssl;
  server_name example.com;

  root /home/dclo/example;
  index /index.html;
  error_page 404 /index.html;

  # ... ssl configuration
}

In this case, I wanted all paths to lead to /index.html, including when returning a 404.

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

I had the same problem with openCV on Raspberry Pi... don't know if this can solve your problem, but what worked for me was

import time
import cv2


cap = cv2.VideoCapture(0)

cap.set(3,1280)

cap.set(4,1024)

time.sleep(2)

cap.set(15, -8.0)

the time you have to use can be different

In case you don't want to inherit from dict as others have suggested, here is direct answer to the question on how to implement __iter__ for a crude example of a custom dict:

class Attribute:
    def __init__(self, key, value):
        self.key = key
        self.value = value

class Node(collections.Mapping):
    def __init__(self):
        self.type  = ""
        self.attrs = [] # List of Attributes

    def __iter__(self):
        for attr in self.attrs:
            yield attr.key

That uses a generator, which is well described here.

Since we're inheriting from Mapping, you need to also implement __getitem__ and __len__:

    def __getitem__(self, key):
        for attr in self.attrs:
            if key == attr.key:
                return attr.value
        raise KeyError

    def __len__(self):
        return len(self.attrs)

You can bind listeners to one common functions -

$(window).bind("load resize scroll",function(e){
  // do stuff
});

Or another way -

$(window).bind({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

Alternatively, instead of using .bind() you can use .on() as bind directly maps to on(). And maybe .bind() won't be there in future jquery versions.

$(window).on({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

You can check if the object is produced by JQuery with the jquery property:

myObject.jquery // 3.3.1

=> return the number of the JQuery version if the object produced by JQuery. => otherwise, it returns undefined

in C# there is no Java like hidden override, without keyword override on overriding method! see these C# implementations:

variant 1 without override: result is 200

    class Car {
        public int topSpeed() {
            return 200;
        }
    }

    class Ferrari : Car {
        public int topSpeed(){
                return 400;
        }
    }

    static void Main(string[] args){
        Car car = new Ferrari();
        int num= car.topSpeed();
        Console.WriteLine("Top speed for this car is: "+num);
        Console.ReadLine();
    }

variant 2 with override keyword: result is 400

    class Car {
        public virtual int topSpeed() {
            return 200;
        }
    }

    class Ferrari : Car {
        public override int topSpeed(){
                return 400;
        }
    }

    static void Main(string[] args){
        Car car = new Ferrari();
        int num= car.topSpeed();
        Console.WriteLine("Top speed for this car is: "+num);
        Console.ReadLine();
    }

keyword virtual on Car class is opposite for final on Java, means not final, you can override, or implement if Car was abstract

This nodejs code just do that , as @Felix Yan mentioned former way seems to work just fine , i had some issues with other snipets hope this helps.

This will rename column "oldColumnName" to be "newColumnName" of table "documents"

var MongoClient = require('mongodb').MongoClient
  , assert = require('assert');

// Connection URL
//var url = 'mongodb://localhost:27017/myproject';
var url = 'mongodb://myuser:[email protected]:portNumber/databasename';

// Use connect method to connect to the server
MongoClient.connect(url, function(err, db) {
  assert.equal(null, err);
  console.log("Connected successfully to server");

  renameDBColumn(db, function() {
    db.close();
  });

});

//
// This function should be used for renaming a field for all documents
//
var renameDBColumn = function(db, callback) {
  // Get the documents collection
  console.log("renaming database column of table documents");
  //use the former way:
  remap = function (x) {
    if (x.oldColumnName){
      db.collection('documents').update({_id:x._id}, {$set:{"newColumnName":x.oldColumnName}, $unset:{"oldColumnName":1}});
    }
  }

  db.collection('documents').find().forEach(remap);
  console.log("db table documents remap successfully!");
}

I think your question has already been answered more than adequately, but it might be useful to point out explicitly that given a function pointer

void (*pf)(int foo, int bar);

the two calls

pf(1, 0);
(*pf)(1, 0);

are exactly equivalent in every way by definition. The choice of which to use is up to you, although it's a good idea to be consistent. For a long time, I preferred (*pf)(1, 0) because it seemed to me that it better reflected the type of pf, however in the last few years I've switched to pf(1, 0).

If you wish the delete to be automatic, you need to change your schema so that the foreign key constraint is ON DELETE CASCADE.

For more information, see the MSDN page on Cascading Referential Integrity Constraints.

ETA (after clarification from the poster): If you can't update the schema, you have to manually DELETE the affected child records first.

I tried a lot of ways and functions that suggested above, but they didn't work in my project. Anyway I have found solution and here it is:

try {
    InputStream path = this.getClass().getClassLoader().getResourceAsStream("img/left-hand.png");
    img = ImageIO.read(path);
} catch (IOException e) {
    e.printStackTrace();
}

I know that I am late but, I happen to see this and I have a suggestion.. For those looking for cross-browser support, I wouldn't recommend class toggling via JS. It may be a little more work but it is more supported through all browsers.

document.getElementById("myButton").addEventListener('click', themeswitch);

function themeswitch() {
  const Body = document.body
  if (Body.style.backgroundColor === 'white') {
    Body.style.backgroundColor = 'black';
  } else {
    Body.style.backgroundColor = 'white';
  }
}

body {
  background: white;
}

<button id="myButton">Switch</button>

var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');

Change this line from your code to this -

var userPasswordString = Buffer.from(baseAuth, 'base64').toString('ascii');

or in my case, I gave the encoding in reverse order

var userPasswordString = Buffer.from(baseAuth, 'utf-8').toString('base64');

curl_setopt($ch, CURLOPT_HTTPHEADER, array(

    'X-Apple-Store-Front: 143444,12'
));

Try this more succinct code:

Sub LoopOverEachColumn()
    Dim WS As Worksheet
    For Each WS In ThisWorkbook.Worksheets
        ResizeColumns WS
    Next WS
End Sub

Private Sub ResizeColumns(WS As Worksheet)
    Dim StrSize As String
    Dim ColIter As Long
    StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
    For ColIter = 1 To 15
        WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
    Next ColIter
End Sub

If you want additional columns, just change 1 to 15 to 1 to X where X is the column index of the column you want, and append the column size you want to StrSize.

For example, if you want P:P to have a width of 25, just add ;25 to StrSize and change ColIter... to ColIter = 1 to 16.

Hope this helps.

I also faced the same problem. In my case I was hitting a java.util.UnknownFormatConversionException. I figured this out only after putting a printStackTrace call. I resolved it by changing my code as shown below.

from:

StringBuilder sb = new StringBuilder();
sb.append("***** Test Details *****\n");
String.format("[Test: %1]", sb.toString());

to:

String.format("[Test: %s]", sb.toString());

They are the same.

Both mean that when coming in to the load balancer, the request will be directed to the server that served the first request (and has the session).

I think you are editing something in the windows registry but that has no effect on the path.

Try this:

How to Add, Remove or Edit Environment variables in Windows 7

the variable of interest is the PATH

also you can type on the command line:

Set PATH=%PATH%;(your new path);

You've got it right there except for "end". It's called slice notation. Your example should read:

new_sub_string = myString[2:]

If you leave out the second parameter it is implicitly the end of the string.

A submodule is nothing but a clone of a git repo within another repo with some extra meta data (gitlink tree entry, .gitmodules file )

$ cd your_submodule
$ git checkout master
<hack,edit>
$ git commit -a -m "commit in submodule"
$ git push
$ cd ..
$ git add your_submodule
$ git commit -m "Updated submodule"

Alternative Methods

The Math.min and Math.max methods are both recursive operations that being added to the JS engine's call stack, and most likely crash for an array that contains large number of items
(more than ~107 items, depends on the user's browser).

Uncaught RangeError: Maximum call stack size exceeded

Instead, consider using something like so:

arr.reduce((max, val) => max > val ? max : val)

Or with better run-time:

function maxValue(arr) {
  let max = arr[0];

  for (let val of arr) {
    if (val > max) {
      max = val;
    }
  }
  return max;
}

Or to get both Min and Max:

function getMinMax(arr) {
  return arr.reduce(({min, max}, v) => ({
    min: min < v ? min : v,
    max: max > v ? max : v,
  }), { min: arr[0], max: arr[0] });
}

Or with even better run-time*:

function getMinMax(arr) {
  let min = arr[0];
  let max = arr[0];
  let i = arr.length;
    
  while (i--) {
    min = arr[i] < min ? arr[i] : min;
    max = arr[i] > max ? arr[i] : max;
  }
  return { min, max };
}

* Tested with 1,000,000 items:
Just for a reference, the 1st function run-time (on my machine) was 15.84ms vs 2nd function with only 4.32ms.

Arrays themselves do not have that method. A List, however, does: indexOf

This can also be a cause for this[:) I solved my problem like this]

It may happen even if you are trying to insert a dataframe type column inside dataframe

you can try this

df['my_new']=pd.Series(my_new.values)

This code which you have written, is not producing correct BFS traversal: (This is the code you claimed is BFS, but in fact this is DFS!)

//  search traversal
  public void breadth(TreeNode root){
      if (root == null)
          return;

      System.out.print(root.element + " ");
      breadth(root.left);
      breadth(root.right);
 }

Nothing of the above was able to help me. In my scenario the issue was showing itself like this:

• Any ll command was slow (was taking about 3 seconds to execute)
• Any subsequent ll command was executed instantly, but only if within 45 seconds from the previous ls command.

When it came to debugging with Process Monitor it was found that before every command there was a DNS request.

So as soon as I disabled my firewall (Comodo in my case) and let the command execute the issue is gone. And it is not returning back when the firewall was switched back on. With the earliest opportunity I'll update this response with more details about what process was doing a blocking DNS request and what was the target.

  },
  cache: false
});

31-DEC-95 isn't a string, nor is 20-JUN-94. They're numbers with some extra stuff added on the end. This should be '31-DEC-95' or '20-JUN-94' - note the single quote, '. This will enable you to do a string comparison.

However, you're not doing a string comparison; you're doing a date comparison. You should transform your string into a date. Either by using the built-in TO_DATE() function, or a date literal.

TO_DATE()

select employee_id
  from employee
 where employee_date_hired > to_date('31-DEC-95','DD-MON-YY')

This method has a few unnecessary pitfalls

• As a_horse_with_no_name noted in the comments, DEC, doesn't necessarily mean December. It depends on your NLS_DATE_LANGUAGE and NLS_DATE_FORMAT settings. To ensure that your comparison with work in any locale you can use the datetime format model MM instead
• The year '95 is inexact. You know you mean 1995, but what if it was '50, is that 1950 or 2050? It's always best to be explicit

select employee_id
  from employee
 where employee_date_hired > to_date('31-12-1995','DD-MM-YYYY')

Date literals

A date literal is part of the ANSI standard, which means you don't have to use an Oracle specific function. When using a literal you must specify your date in the format YYYY-MM-DD and you cannot include a time element.

select employee_id
  from employee
 where employee_date_hired > date '1995-12-31'

Remember that the Oracle date datatype includes a time elemement, so the date without a time portion is equivalent to 1995-12-31 00:00:00.

If you want to include a time portion then you'd have to use a timestamp literal, which takes the format YYYY-MM-DD HH24:MI:SS[.FF0-9]

select employee_id
  from employee
 where employee_date_hired > timestamp '1995-12-31 12:31:02'

Further information

NLS_DATE_LANGUAGE is derived from NLS_LANGUAGE and NLS_DATE_FORMAT is derived from NLS_TERRITORY. These are set when you initially created the database but they can be altered by changing your inialization parameters file - only if really required - or at the session level by using the ALTER SESSION syntax. For instance:

alter session set nls_date_format = 'DD.MM.YYYY HH24:MI:SS';

This means:

• DD numeric day of the month, 1 - 31
• MM numeric month of the year, 01 - 12 ( January is 01 )
• YYYY 4 digit year - in my opinion this is always better than a 2 digit year YY as there is no confusion with what century you're referring to.
• HH24 hour of the day, 0 - 23
• MI minute of the hour, 0 - 59
• SS second of the minute, 0-59

You can find out your current language and date language settings by querying V$NLS_PARAMETERSs and the full gamut of valid values by querying V$NLS_VALID_VALUES.

• Format models

Incidentally, if you want the count(*) you need to group by employee_id

select employee_id, count(*)
  from employee
 where employee_date_hired > date '1995-12-31'
 group by employee_id

This gives you the count per employee_id.

I did most of the suggested stuff here, still didnt work. Tried this and it worked: Open your XAMPP Control Panel, locate the Config button for the Apache module. Click on the Config button and Select PHP (php.ini). Open with any text editor and remove the semi-column before php_openssl. Save and Restart Apache. That should do!

xml.etree.ElementTree vs. lxml

These are some pros of the two most used libraries I would have benefit to know before choosing between them.

xml.etree.ElementTree:

1. From the standard library: no needs of installing any module

lxml

1. Easily write XML declaration: for instance do you need to add standalone="no"?
2. Pretty printing: you can have a nice indented XML without extra code.
3. Objectify functionality: It allows you to use XML as if you were dealing with a normal Python object hierarchy.node.
4. sourceline allows to easily get the line of the XML element you are using.
5. you can use also a built-in XSD schema checker.

Like this:

Dim rng as Range
Set rng = ActiveCell.Resize(numRows, numCols)

then read the contents of that range to an array:

Dim arr As Variant
arr = rng.Value
'arr is now a two-dimensional array of size (numRows, numCols)

or, select the range (I don't think that's what you really want, but you ask for this in the question).

rng.Select

I know nothing about the Python interpreter inner workings (and I'm not an expert in compilers and interpreters either) so don't blame me if I propose anything unsensible or impossible.

Provided that python objects are mutable I think that this should be taken into account when designing the default arguments stuff. When you instantiate a list:

a = []

you expect to get a new list referenced by a.

Why should the a=[] in

def x(a=[]):

instantiate a new list on function definition and not on invocation? It's just like you're asking "if the user doesn't provide the argument then instantiate a new list and use it as if it was produced by the caller". I think this is ambiguous instead:

def x(a=datetime.datetime.now()):

user, do you want a to default to the datetime corresponding to when you're defining or executing x? In this case, as in the previous one, I'll keep the same behaviour as if the default argument "assignment" was the first instruction of the function (datetime.now() called on function invocation). On the other hand, if the user wanted the definition-time mapping he could write:

b = datetime.datetime.now()
def x(a=b):

I know, I know: that's a closure. Alternatively Python might provide a keyword to force definition-time binding:

def x(static a=b):

If you want time in 00:00 format: I solved it like that:

select strftime('%H:%M',CAST ((julianday(FinishTime) - julianday(StartTime)) AS REAL),'12:00') from something

git clone --depth 1 --branch <tag_name> <repo_url>

--depth 1 is optional but if you only need the state at that one revision, you probably want to skip downloading all the history up to that revision.

Using PowerShell, you can use the following

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Select name

This will show a list off all services which displayname starts with "NATION-".

You can also directly stop or start the services;

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Stop-Service
Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Start-Service

or simply

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Restart-Service

java8 and further

Set<String> set = new TreeSet<>();
    set.add("2");
    set.add("1");
    set.add("3");
    String first = set.stream().findFirst().get();

This will help you retrieve the first element of the list or set. Given that the set or list is not empty (get() on empty optional will throw java.util.NoSuchElementException)

orElse() can be used as: (this is just a work around - not recommended)

String first = set.stream().findFirst().orElse("");
set.removeIf(String::isEmpty);

Below is the appropriate approach :

Optional<String> firstString = set.stream().findFirst();
if(firstString.isPresent()){
    String first = firstString.get();
}

Similarly first element of the list can be retrieved.

Hope this helps.

The most simple way is to use Record type Record<number, productDetails >

interface productDetails {
   productId : number , 
   price : number , 
   discount : number
};

const myVar : Record<number, productDetails> = {
   1: {
       productId : number , 
       price : number , 
       discount : number
   }
}

I'm forced to post this as an answer instead of a comment due to low reputation. I had a similar problem to Matteo. The difference being that I had no map from my first x-axis to my second x-axis, only the x-values themselves. So I wanted to set the data on my second x-axis directly, not the ticks, however, there is no axes.set_xdata. I was able to use Dhara's answer to do this with a modification:

ax2.lines = []

instead of using:

ax2.cla()

When in use also cleared my plot from ax1.

Consider two ways of doing the same thing:

PreparedStatement stmt = conn.createStatement("INSERT INTO students VALUES('" + user + "')");
stmt.execute();

Or

PreparedStatement stmt = conn.prepareStatement("INSERT INTO student VALUES(?)");
stmt.setString(1, user);
stmt.execute();

If "user" came from user input and the user input was

Robert'); DROP TABLE students; --

Then in the first instance, you'd be hosed. In the second, you'd be safe and Little Bobby Tables would be registered for your school.

you should be using the .Value of the datetime parameter. All Nullable structs have a value property which returns the concrete type of the object. but you must check to see if it is null beforehand otherwise you will get a runtime error.

i.e:

datetime.Value

but check to see if it has a value first!

if (datetime.HasValue)
{
   // work with datetime.Value
}

C++20 std::format options <, ^ and >

According to https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification the following should hold:

// left: "42    "
std::cout << std::format("{:<6}", 42);

// right: "    42"
std::cout << std::format("{:>6}", 42);

// center: "  42  "
std::cout << std::format("{:^6}", 42);

More information at: std::string formatting like sprintf

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

FYI : How to download data in CSV from Kibana:

In Kibana--> 1. Go to 'Discover' in left side

2. Select Index Field (based on your dashboard data) (*** In case if you are not sure which index to select-->go to management tab-->Saved Objects-->Dashboard-->select dashboard name-->scroll down to JSON-->you will see the Index name )

3. left side you see all the variables available in the data-->click over the variable name that you want to have in csv-->click add-->this variable will be added on the right side of the columns avaliable

4. Top right section of the kibana-->there is the time filter-->click -->select the duration for which you want the csv

5. Top upper right -->Reporting-->save this time/variable selection with a new report-->click generate CSV

6. Go to 'Management' in left side--> 'Reporting'-->download your csv

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

<a href="javascript:window.open('document.aspx','mypopuptitle','width=600,height=400')">open popup</a>

You've almost done it. However setting flex: 0 0 <basis> declaration to the columns would prevent them from growing/shrinking; And the <basis> parameter would define the width of columns.

In addition, you could use CSS3 calc() expression to specify the height of columns with the respect to the height of the header.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  flex: 0 0 100%; /* Let it fill the entire space horizontally */_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 0 0 66%; /* ~ 2 * 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 0 0 34%;  /* ~ 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: black;_x000D_
}

<div id="productShowcaseContainer">_x000D_
  <div id="productShowcaseTitle"></div>_x000D_
  <div id="productShowcaseDetail"></div>_x000D_
  <div id="productShowcaseThumbnailContainer"></div>_x000D_
</div>

(Vendor prefixes omitted due to brevity)

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div> element, it would be achieved without using calc() as follows:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;
  flex-direction: column;
  height: 600px; width: 580px;
}

.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
.contentContainer {_x000D_
  display: flex;_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 3;_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 2;_x000D_
  background-color: black;_x000D_
}

<div id="productShowcaseContainer">_x000D_
  <div id="productShowcaseTitle"></div>_x000D_

The formula provided by Blake doesn't seem to work for me. For past dates it returns due in xx days and for future dates, it returns overdue. Also, it will only return 15 days overdue, when it could actually be 30, 60 90+.

I created this, which seems to work and provides 'Due in xx days', 'Overdue xx days' and 'Due Today'.

=IF(ISBLANK(O10),"",IF(DAYS(TODAY(),O10)<0,CONCATENATE("Due in ",-DAYS(TODAY(),O10)," Days"),IF(DAYS(TODAY(),O10)>0,CONCATENATE("Overdue ",DAYS(TODAY(),O10)," Days"),"Due Today")))

For me, the easiest solution would be keep value when count is equal to the maximum. Therefore, the following one line command is enough :

df[df['count'] == df.groupby(['Mt'])['count'].transform(max)]

Edit: see the end examples for ES6 updated examples.

This answer simply handle the case of direct parent-child relationship. When parent and child have potentially a lot of intermediaries, check this answer.

Other solutions are missing the point

While they still work fine, other answers are missing something very important.

Is there not a simple way to pass a child's props to its parent using events, in React.js?

The parent already has that child prop!: if the child has a prop, then it is because its parent provided that prop to the child! Why do you want the child to pass back the prop to the parent, while the parent obviously already has that prop?

Better implementation

Child: it really does not have to be more complicated than that.

var Child = React.createClass({
  render: function () {
    return <button onClick={this.props.onClick}>{this.props.text}</button>;
  },
});

Parent with single child: using the value it passes to the child

var Parent = React.createClass({
  getInitialState: function() {
     return {childText: "Click me! (parent prop)"};
  },
  render: function () {
    return (
      <Child onClick={this.handleChildClick} text={this.state.childText}/>
    );
  },
  handleChildClick: function(event) {
     // You can access the prop you pass to the children 
     // because you already have it! 
     // Here you have it in state but it could also be
     //  in props, coming from another parent.
     alert("The Child button text is: " + this.state.childText);
     // You can also access the target of the click here 
     // if you want to do some magic stuff
     alert("The Child HTML is: " + event.target.outerHTML);
  }
});

JsFiddle

Parent with list of children: you still have everything you need on the parent and don't need to make the child more complicated.

var Parent = React.createClass({
  getInitialState: function() {
     return {childrenData: [
         {childText: "Click me 1!", childNumber: 1},
         {childText: "Click me 2!", childNumber: 2}
     ]};
  },
  render: function () {
    var children = this.state.childrenData.map(function(childData,childIndex) {
        return <Child onClick={this.handleChildClick.bind(null,childData)} text={childData.childText}/>;
    }.bind(this));
    return <div>{children}</div>;
  },

  handleChildClick: function(childData,event) {
     alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
     alert("The Child HTML is: " + event.target.outerHTML);
  }
});

JsFiddle

It is also possible to use this.handleChildClick.bind(null,childIndex) and then use this.state.childrenData[childIndex]

Note we are binding with a null context because otherwise React issues a warning related to its autobinding system. Using null means you don't want to change the function context. See also.

About encapsulation and coupling in other answers

This is for me a bad idea in term of coupling and encapsulation:

var Parent = React.createClass({
  handleClick: function(childComponent) {
     // using childComponent.props
     // using childComponent.refs.button
     // or anything else using childComponent
  },
  render: function() {
    <Child onClick={this.handleClick} />
  }
});

Using props: As I explained above, you already have the props in the parent so it's useless to pass the whole child component to access props.

Using refs: You already have the click target in the event, and in most case this is enough. Additionnally, you could have used a ref directly on the child:

<Child ref="theChild" .../>

And access the DOM node in the parent with

React.findDOMNode(this.refs.theChild)

For more advanced cases where you want to access multiple refs of the child in the parent, the child could pass all the dom nodes directly in the callback.

The component has an interface (props) and the parent should not assume anything about the inner working of the child, including its inner DOM structure or which DOM nodes it declares refs for. A parent using a ref of a child means that you tightly couple the 2 components.

To illustrate the issue, I'll take this quote about the Shadow DOM, that is used inside browsers to render things like sliders, scrollbars, video players...:

They created a boundary between what you, the Web developer can reach and what’s considered implementation details, thus inaccessible to you. The browser however, can traipse across this boundary at will. With this boundary in place, they were able to build all HTML elements using the same good-old Web technologies, out of the divs and spans just like you would.

The problem is that if you let the child implementation details leak into the parent, you make it very hard to refactor the child without affecting the parent. This means as a library author (or as a browser editor with Shadow DOM) this is very dangerous because you let the client access too much, making it very hard to upgrade code without breaking retrocompatibility.

If Chrome had implemented its scrollbar letting the client access the inner dom nodes of that scrollbar, this means that the client may have the possibility to simply break that scrollbar, and that apps would break more easily when Chrome perform its auto-update after refactoring the scrollbar... Instead, they only give access to some safe things like customizing some parts of the scrollbar with CSS.

About using anything else

Passing the whole component in the callback is dangerous and may lead novice developers to do very weird things like calling childComponent.setState(...) or childComponent.forceUpdate(), or assigning it new variables, inside the parent, making the whole app much harder to reason about.

Edit: ES6 examples

As many people now use ES6, here are the same examples for ES6 syntax

The child can be very simple:

const Child = ({
  onClick, 
  text
}) => (
  <button onClick={onClick}>
    {text}
  </button>
)

The parent can be either a class (and it can eventually manage the state itself, but I'm passing it as props here:

class Parent1 extends React.Component {
  handleChildClick(childData,event) {
     alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
     alert("The Child HTML is: " + event.target.outerHTML);
  }
  render() {
    return (
      <div>
        {this.props.childrenData.map(child => (
          <Child
            key={child.childNumber}
            text={child.childText} 
            onClick={e => this.handleChildClick(child,e)}
          />
        ))}
      </div>
    );
  }
}

But it can also be simplified if it does not need to manage state:

const Parent2 = ({childrenData}) => (
  <div>
     {childrenData.map(child => (
       <Child
         key={child.childNumber}
         text={child.childText} 
         onClick={e => {
            alert("The Child button data is: " + child.childText + " - " + child.childNumber);
                    alert("The Child HTML is: " + e.target.outerHTML);
         }}
       />
     ))}
  </div>
)

JsFiddle

PERF WARNING (apply to ES5/ES6): if you are using PureComponent or shouldComponentUpdate, the above implementations will not be optimized by default because using onClick={e => doSomething()}, or binding directly during the render phase, because it will create a new function everytime the parent renders. If this is a perf bottleneck in your app, you can pass the data to the children, and reinject it inside "stable" callback (set on the parent class, and binded to this in class constructor) so that PureComponent optimization can kick in, or you can implement your own shouldComponentUpdate and ignore the callback in the props comparison check.

You can also use Recompose library, which provide higher order components to achieve fine-tuned optimisations:

// A component that is expensive to render
const ExpensiveComponent = ({ propA, propB }) => {...}

// Optimized version of same component, using shallow comparison of props
// Same effect as React's PureRenderMixin
const OptimizedComponent = pure(ExpensiveComponent)

// Even more optimized: only updates if specific prop keys have changed
const HyperOptimizedComponent = onlyUpdateForKeys(['propA', 'propB'])(ExpensiveComponent)

In this case you could optimize the Child component by using:

const OptimizedChild = onlyUpdateForKeys(['text'])(Child)

This is in VB.NET, just translate to C# if you need it:

<Extension()>
Public Function FindControlInRepeaterHeader(Of T As Control)(obj As Repeater, ControlName As String) As T
    Dim ctrl As T = TryCast((From item As RepeaterItem In obj.Controls
                   Where item.ItemType = ListItemType.Header).SingleOrDefault.FindControl(ControlName),T)
    Return ctrl
End Function

And use it easy:

Dim txt as string = rptrComentarios.FindControlInRepeaterHeader(Of Label)("lblVerTodosComentarios").Text

Try to make it work with footer, and items controls too =)

Have you tried moving the reduction step outside the loop? Right now you have a data dependency that really isn't needed.

Try:

  uint64_t subset_counts[4] = {};
  for( unsigned k = 0; k < 10000; k++){
     // Tight unrolled loop with unsigned
     unsigned i=0;
     while (i < size/8) {
        subset_counts[0] += _mm_popcnt_u64(buffer[i]);
        subset_counts[1] += _mm_popcnt_u64(buffer[i+1]);
        subset_counts[2] += _mm_popcnt_u64(buffer[i+2]);
        subset_counts[3] += _mm_popcnt_u64(buffer[i+3]);
        i += 4;
     }
  }
  count = subset_counts[0] + subset_counts[1] + subset_counts[2] + subset_counts[3];

You also have some weird aliasing going on, that I'm not sure is conformant to the strict aliasing rules.

If you came here because you deal with class instances like me you can use static vars/methods to reference instances by a custom unique id:

class Person { 
    constructor( name ) {
        this.name = name;
        this.id = Person.ix++;
        Person.stack[ this.id ] = this;
    }
}
Person.ix = 0;
Person.stack = {};
Person.byId = id => Person.stack[ id ];

let store = {};
store[ new Person( "joe" ).id ] = true;
store[ new Person( "tim" ).id ] = true;

for( let id in store ) {
    console.log( Person.byId( id ).name );
}

printf("\nmaximum of %d and %d is = %d",a,b,c);

You mention the user switching between Activities pretty quickly. Could it be that you're calling unbindService before the service connection has been established? This may have the effect of failing to unbind, then leaking the binding.

Not entirely sure how you could handle this... Perhaps when onServiceConnected is called you could call unbindService if onDestroy has already been called. Not sure if that'll work though.

If you haven't already, you could add an onUnbind method to your service. That way you can see exactly when your classes unbind from it, and it might help with debugging.

@Override
public boolean onUnbind(Intent intent) {
    Log.d(this.getClass().getName(), "UNBIND");
    return true;
}

For example if you navigate from viewControllerB to viewControllerA then in your viewControllerA below delegate will call and data will share.

@IBAction func unWindSeague (_ sender : UIStoryboardSegue) {
        if sender.source is ViewControllerB  {
            if let _ = sender.source as? ViewControllerB {
                self.textLabel.text = "Came from B = B->A , B exited"
            }
            
        }

}

• Unwind Seague Source View Controller ( You Need to connect Exit Button to VC’s exit icon and connect it to unwindseague:

• Unwind Seague Completed -> TextLabel of viewControllerA is Changed.

Simple way for newbie:

title.ToLower().Contains("string");//of course "string" is lowercase.

If the branch is on something other than the origin remote I like to do the following:

$ git fetch
$ git checkout -b second/next upstream/next

This will checkout the next branch on the upstream remote in to a local branch called second/next. Which means if you already have a local branch named next it will not conflict.

$ git branch -a
* second/next
  remotes/origin/next
  remotes/upstream/next

Try the following simple function:

function _flatten_array($arr) {
  while ($arr) {
    list($key, $value) = each($arr); 
    is_array($value) ? $arr = $value : $out[$key] = $value;
    unset($arr[$key]);
  }
  return (array)$out;
}

So from this:

array (
  'und' => 
  array (
    'profiles' => 
    array (
      0 => 
      array (
        'commerce_customer_address' => 
        array (
          'und' => 
          array (
            0 => 
            array (
              'first_name' => 'First name',
              'last_name' => 'Last name',
              'thoroughfare' => 'Address 1',
              'premise' => 'Address 2',
              'locality' => 'Town/City',
              'administrative_area' => 'County',
              'postal_code' => 'Postcode',
            ),
          ),
        ),
      ),
    ),
  ),
)

you get:

array (
  'first_name' => 'First name',
  'last_name' => 'Last name',
  'thoroughfare' => 'Address 1',
  'premise' => 'Address 2',
  'locality' => 'Town/City',
  'administrative_area' => 'County',
  'postal_code' => 'Postcode',
)

An even cleaner and more professional look I have found is to use AngularUI Mask. Very simple to implement and the mask can be customized for other inputs as well. Then a simple required validation is all you need.

It appears that your format is incorrect:

If you want to share a locally created repository, or you want to take contributions from someone elses repository - if you want to interact in any way with a new repository, it's generally easiest to add it as a remote. You do that by running git remote add [alias] [url]. That adds [url] under a local remote named [alias].

#example
$ git remote
$ git remote add github [email protected]:schacon/hw.git
$ git remote -v

http://gitref.org/remotes/#remote

In the detached window (Tool Options), the name of the view (Paintbrush) is a grab-bar.

Put your cursor over the grab-bar, click and drag it to the dock area in the main window in order to reattach it to the main window.

var model = {"Id": "xx", "Name":"Ravi"};
$.ajax({    url: 'test/set',
                        type: "POST",
                        data: model,
                        success: function (res) {
                            if (res != null) {
                                alert("done.");
                            }
                        },
                        error: function (res) {

                        }
                    });

Forms in C# are classes that inherit the Form base class.

You can show a popup by creating an instance of the class and calling ShowDialog().

When you are appending data into div by id using any service or database, first try it empty, like this:

var json = jsonParse(data.d);
$('#divname').empty();

Not smarter but simpler:

select info->>'name' from rabbits WHERE info->>'food' LIKE '%"carrots"%';

You use an enum instead of a class if the class should have a fixed enumerable number of instances.

Examples:

• DayOfWeek  = 7 instances ? enum
• CardSuit    = 4 instances ? enum
• Singleton  = 1 instance   ? enum

You use ComponentScan to scan multiple packages using

@ComponentScan({"com.my.package.first","com.my.package.second"})

Every iteration you are resetting the sequence of pseudorandom numbers because you are calling srand with the same seed (since the call to time is so frequent). Either use a different seed, or call srand once before you enter the loop.

LINQ has its origins in functional programming, which emphasises immutability of objects, so it doesn't provide a built-in way to update the original list in-place.

Note on immutability (taken from another SO answer):

Here is the definition of immutability from Wikipedia.

In object-oriented and functional programming, an immutable object is an object whose state cannot be modified after it is created.

You can create external command Run -> External Tools -> External Tools Configuration...

It will be available under Run -> External Tools and can be run using shortcuts.

When you say adding antMatchers doesnt help - what do you mean? antMatchers is exactly how you do it. Something like the following should work (obviously changing your URL appropriately):

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/authFailure").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()

If you are still not having any joy, then you will need to provide more details/stacktrace etc.

I have found that using Thread.sleep(milliseconds) helps almost all the time for me. It takes time for the element to load hence it is not interactable. So i put Thread.sleep() after selecting each value. So far this has helped me avoid the error.

try {Thread.sleep(3000);} catch (InterruptedException e) {e.printStackTrace();}

        Select nationalityDropdown=new Select(driver.findElement(By.id("ContentPlaceHolderMain_ddlNationality")));

        nationalityDropdown.selectByValue("Indian");

        try {Thread.sleep(3000);} catch (InterruptedException e) {e.printStackTrace();}     

Microsoft has the Windows Performance Toolkit.

It does require Windows Vista, Windows Server 2008, or Windows 7.

Please use this on SQL Server 2005:

sp_rename old_table_name , new_table_name

it will give you:

Caution: Changing any part of an object name could break scripts and stored procedures.

but your table name will be changed.

This worked for me:

       jQuery('#tblPaging').dataTable({
            "sort": true,
            "pageLength": 20
        });

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

Place it in your bash profile:

~/.bash_profile

I noticed some time ago that a For loop typically generates several more machine instructions than a while loop. However, if you look closely at the examples, which mirror my observations, the difference is two or three machine instructions, hardly worth much consideration.

Note, too, that the initializer for a WHILE loop can be eliminated by baking it into the code, e. g.:

static int intStartWith = 100;

The static modifier bakes the initial value into the code, saving (drum roll) one MOV instruction. Of greater significance, marking a variable as static moves it outside the stack frame. Variable alignment permitting, it may also produce slightly smaller code, too, since the MOV instruction and its operands take more room than, for example an integer, Boolean, or character value (either ANSI or Unicode).

However, if variables are aligned on 8 byte boundaries, a common default setting, an int, bool, or TCHAR baked into code costs the same number of bytes as a MOV instruction.

What should happen if there are more than 1 longest string (think '12', and '01')?

Try that to get the longest element

max_length,longest_element = max([(len(x),x) for x in ('a','b','aa')])

And then regular foreach

for st in mylist:
    if len(st)==max_length:...

I have recently encountered this problem. Here are the steps to resolve

1. Check the servers section in the settings.xml file.Is username and password correct?

<servers>_x000D_
  <server>_x000D_
    <id>serverId</id>_x000D_
    <username>username</username>_x000D_
    <password>password</password>_x000D_
  </server>_x000D_
</servers>

2. Check the repository section in the pom.xml file.The id of the server tag should be the same as the id of the repository tag.

<repositories>_x000D_
 <repository>_x000D_
   <id>serverId</id>  _x000D_
   <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
 </repository>_x000D_
</repositories>

3. If the repository tag is not configured in the pom.xml file, look in the settings.xml file.

<profiles>_x000D_
 <profile>_x000D_
   <repositories>_x000D_
     <repository>_x000D_
      <id>serverId</id>_x000D_
      <name>aliyun</name>_x000D_
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
     </repository>_x000D_
   </repositories>_x000D_
 </profile>_x000D_
</profiles>

Note that you should ensure that the id of the server tag should be the same as the id of the repository tag.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

As far as I know, there's no method to do what you want; at least not directly. I'd store the photosLocation as a path relative to the application; for example: "~/Images/". This way, you could use MapPath to get the physical location, and ResolveUrl to get the URL (with a bit of help from System.IO.Path):

string photosLocationPath = HttpContext.Current.Server.MapPath(photosLocation);
if (Directory.Exists(photosLocationPath))
{
    string[] files = Directory.GetFiles(photosLocationPath, "*.jpg");
    if (files.Length > 0)
    {
        string filenameRelative = photosLocation +  Path.GetFilename(files[0])   
        return Page.ResolveUrl(filenameRelative);
    }
}

I think this is the shortest way. I tested it on Chrome and MS Edge.

$(document).on('click', 'input:radio', function () {
    var check = $(this).attr('checked')
    if (check) $(this).removeAttr('checked').prop('checked',false)
    else $(this).attr('checked', true).prop('checked',true)
})

This piece of code also works on AJAX loaded contents.

Alternatively, You can also use

$(document).on('click mousedown', 'input:radio', function (e) {
    e.preventDefault()
    if ($(this).prop('checked')) $(this).prop('checked', false)
    else $(this).prop('checked', true)
})

This would work better without any exceptions.

Some IDEs highlight the code in heredoc strings automatically - which makes using heredoc for XML or HTML visually appealing.

I personally like it for longer parts of i.e. XML since I don't have to care about quoting quote characters and can simply paste the XML.

According to the git-stash manpage, "A stash is represented as a commit whose tree records the state of the working directory, and its first parent is the commit at HEAD when the stash was created," and git stash show -p gives us "the changes recorded in the stash as a diff between the stashed state and its original parent.

To keep your other changes intact, use git stash show -p | patch --reverse as in the following:

Edit:

A light improvement to this is to use git apply in place of patch:

Alternatively, you can also use git apply -R as a shorthand to git apply --reverse.

I've been finding this really handy lately...

Since there's no answer stating just this, summarized succinctly:

Carriage Return (MAC pre-OSX)

• CR
• \r
• ASCII code 13

Line Feed (Linux, MAC OSX)

• LF
• \n
• ASCII code 10

Carriage Return and Line Feed (Windows)

• CRLF
• \r\n
• ASCII code 13 and then ASCII code 10

If you see ASCII code in a strange format, they are merely the number 13 and 10 in a different radix/base, usually base 8 (octal) or base 16 (hexadecimal).

http://www.bluesock.org/~willg/dev/ascii.html

typedef is useful for redefining the name of an existing variable type. It provides short & meaningful way to call a datatype. e.g:

typedef unsigned long int TWOWORDS;

here, the type unsigned long int is redefined to be of the type TWOWORDS. Thus, we can now declare variables of type unsigned long int by writing,

TWOWORDS var1, var2;

instead of

unsigned long int var1, var2;

The answers above and on this question either didn't work for me with Selenium 3.14 and Firefox 68.9 on Linux, or are unnecessarily complex. I needed to use a WPAD configuration, sometimes behind a proxy (on a VPN), and sometimes not. After studying the code a bit, I came up with:

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

proxy = Proxy({'proxyAutoconfigUrl': 'http://wpad/wpad.dat'})
profile = FirefoxProfile()
profile.set_proxy(proxy)
driver = webdriver.Firefox(firefox_profile=profile)

The Proxy initialization sets proxyType to ProxyType.PAC (autoconfiguration from a URL) as a side-effect.

It also worked with Firefox's autodetect, using:

from selenium.webdriver.common.proxy import ProxyType

proxy = Proxy({'proxyType': ProxyType.AUTODETECT})

But I don't think this would work with both internal URLs (not proxied) and external (proxied) the way WPAD does. Similar proxy settings should work for manual configuration as well. The possible proxy settings can be seen in the code here.

Note that directly passing the Proxy object as proxy=proxy to the driver does NOT work--it's accepted but ignored (there should be a deprecation warning, but in my case I think Behave is swallowing it).

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

I think this is the Easiest way to populate a table with ResultSet with a method like

FillTable(MyTable, "select * Customers;");

And a very simple method can be made as

public void FillTable(JTable table, String Query)
{
    try
    {
        CreateConnection();
        Statement stat = conn.createStatement();
        ResultSet rs = stat.executeQuery(Query);

        //To remove previously added rows
        while(table.getRowCount() > 0) 
        {
            ((DefaultTableModel) table.getModel()).removeRow(0);
        }
        int columns = rs.getMetaData().getColumnCount();
        while(rs.next())
        {  
            Object[] row = new Object[columns];
            for (int i = 1; i <= columns; i++)
            {  
                row[i - 1] = rs.getObject(i);
            }
            ((DefaultTableModel) table.getModel()).insertRow(rs.getRow()-1,row);
        }

        rs.close();
        stat.close();
        conn.close();
    }
    catch(InstantiationException | IllegalAccessException | SQLException e)
    {
    }
}

Since the question was "display" :

@Html.ValueFor(model => model.RegistrationDate, "{0:dd/MM/yyyy}")

i have used unset() to clear the array but i have come to realize that unset() will render the array null hence the need to re-declare the array like for example

<?php 
    $arr = array();
    array_push($arr , "foo");
    unset($arr); // this will set the array to null hence you need the line below or redeclaring it.
    $arr  = array();

    // do what ever you want here
?>

If I understand correctly you want then of the request function to be called only if request is successful, and you want to ignore errors. To do that you can create a new promise resolve it when axios request is successful and never reject it in case of failure.

Updated code would look something like this:

export function request(method, uri, body, headers) {
  let config = {
    method: method.toLowerCase(),
    url: uri,
    baseURL: API_URL,
    headers: { 'Authorization': 'Bearer ' + getToken() },
    validateStatus: function (status) {
      return status >= 200 && status < 400
    }
  }


  return new Promise(function(resolve, reject) {
    axios(config).then(
      function (response) {
        resolve(response.data)
      }
    ).catch(
      function (error) {
        console.log('Show error notification!')
      }
    )
  });

}

This solution is using javascript to open a new window when a user clicks on your custom share button.

HTML:

<a href="#" onclick="share_fb('http://urlhere.com/test/55d7258b61707022e3050000');return false;" rel="nofollow" share_url="http://urlhere.com/test/55d7258b61707022e3050000" target="_blank">

  //using fontawesome
  <i class="uk-icon-facebook uk-float-left"></i>
    Share
</a>

and in your javascript file. note window.open params are (url, dialogue title, width, height)

function share_fb(url) {
  window.open('https://www.facebook.com/sharer/sharer.php?u='+url,'facebook-share-dialog',"width=626, height=436")
}

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

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

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

Using

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

Your component might be rendered inside another component (such as a <Typography> ... </Typography>). Therefore, it will load your component inside a <p> .. </p> which is not allowed.

Fix: Remove <Typography>...</Typography> because this is only used for plain text inside a <p>...</p> or any other text element such as headings.

As Brad Wilson states in his answer here:

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Try using :-

if (!ModelState.IsValid)
{
    var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

    // Breakpoint, Log or examine the list with Exceptions.
}

If it helps catching you the error. Courtesy this and this

Basic Functionality

• Automatically saved local edit history is available with the Local History extension.
• Manually saved local edit history is available with the Checkpoints extension (this is the IntelliJ equivalent to adding tags to the local history).

Advanced Functionality

• None of the extensions mentioned above support edit history when a file is moved or renamed.
• The extensions above only support edit history. They do not support move/delete history, for example, like IntelliJ does.

Open Request

If you'd like to see this feature added natively, along with all of the advanced functionality, I'd suggest upvoting the open GitHub issue here.

Another IDE you could try is Aptana.

The simplest way to get the element width without units is :

target.width()

Source : https://api.jquery.com/width/#width2

[contains(text(),'')] only returns true or false. It won't return any element results.

To elaborate on what @Raynos said, the function you have defined is an asynchronous callback. It doesn't execute right away, rather it executes when the file loading has completed. When you call readFile, control is returned immediately and the next line of code is executed. So when you call console.log, your callback has not yet been invoked, and this content has not yet been set. Welcome to asynchronous programming.

Example approaches

const fs = require('fs');
// First I want to read the file
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    const content = data;

    // Invoke the next step here however you like
    console.log(content);   // Put all of the code here (not the best solution)
    processFile(content);   // Or put the next step in a function and invoke it
});

function processFile(content) {
    console.log(content);
}

Or better yet, as Raynos example shows, wrap your call in a function and pass in your own callbacks. (Apparently this is better practice) I think getting into the habit of wrapping your async calls in function that takes a callback will save you a lot of trouble and messy code.

function doSomething (callback) {
    // any async callback invokes callback with response
}

doSomething (function doSomethingAfter(err, result) {
    // process the async result
});

I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.

Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty().

TouchableOpacity receives activeOpacity. You can do something like this

<TouchableOpacity activeOpacity={enabled ? 0.5 : 1}>
</TouchableOpacity>

So if it's enabled, it will look normal, otherwise, it will look just like touchablewithoutfeedback.

you could determine if an object is wrapper type by beneath statements:

***objClass.isAssignableFrom(Number.class);***

and you could also determine a primitive object by using the isPrimitive() method

1. Select a database with identifier mysql_select_db("form1",$connect);

2. Are you getting syntax error? If please put a ; next to $comment = $rows['Comment'].

3. Also the variables should be case sensitive here

Assert allows you to assert a condition (post or pre) applies in your code. It's a way of documenting your intentions and having the debugger inform you with a dialog if your intention is not met.

Unlike a breakpoint, the Assert goes with your code and can be used to add additional detail about your intention.

Pipe the result to wc using the -l (line count) switch:

grep -Rl "curl" ./ | wc -l

For saving the original stdout and stderr you can use:

exec [fd number]<&1 
exec [fd number]<&2

For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.

#!/bin/bash

exec 5<&1
exec 6<&2

exec 1> ~/a.txt 2>&1

echo "walla1"
echo "walla2" >&2
echo "walla3" >&5
echo "walla4" >&6

innerHTML explanation with example:

The innerHTML manipulates the HTML content of an element(get or set). In the example below if you click on the Change Content link it's value will be updated by using innerHTML property of anchor link Change Content

Example:

<a id="example" onclick='testFunction()'>Change Content</a>_x000D_
_x000D_
<script>_x000D_
  function testFunction(){_x000D_
    // change the content using innerHTML_x000D_
    document.getElementById("example").innerHTML = "This is dummy content";_x000D_
_x000D_
    // get the content using innerHTML_x000D_
    alert(document.getElementById("example").innerHTML)_x000D_
_x000D_
  }_x000D_
</script>_x000D_
    

This line:

private dynamic defaultReminder = 
                          reminder.TimeSpanText[TimeSpan.FromMinutes(15)];

You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder will be initialized before defaultReminder, so the above line might throw a NullReferenceException.

Instead, just use:

private dynamic defaultReminder = TimeSpan.FromMinutes(15);

Alternatively, set up the value in the constructor:

private dynamic defaultReminder;

public Reminders()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 
}

There are more details about this compiler error on MSDN - Compiler Error CS0236.

So you want to pass data in body of a GET request, better would be to do it in POST call. You can achieve this by using both Requests.

I use this function to submit triggers:

function travis_trigger() {
     local org=$1 && shift
     local repo=$1 && shift
     local branch=${1:-master} && shift

     body="{
             \"request\": {
               \"branch\": \"${branch}\"
              }
           }"

     curl -s -X POST \
          -H "Content-Type: application/json" \
          -H "Accept: application/json" \
          -H "Travis-API-Version: 3" \
          -H "Authorization: token $TRAVIS_TOKEN" \
          -d "$body" \
          "https://api.travis-ci.org/repo/${org}%2F${repo}/requests"
 }

string connectionstring="DataSource=severname;InitialCatlog=databasename;Uid=; password=;"
SqlConnection con=new SqlConnection(connectionstring)

echo <password> | su -c <command> <user> 

This is working.

// 1. iterate through object values and get them
// 2. sort that array of values ascending or descending and take first, 
//    which is min or max accordingly
let obj = { 'a': 4, 'b': 0.5, 'c': 0.35, 'd': 5 }
let min = Object.values(obj).sort((prev, next) => prev - next)[0] // 0.35
let max = Object.values(obj).sort((prev, next) => next - prev)[0] // 5

Your attempt wasn't that bad. You have to do it with LIKE, yes.

In the manual it says:

Use LIKE to create an empty table based on the definition of another table, including any column attributes and indexes defined in the original table.

So you do:

CREATE TABLE New_Users  LIKE Old_Users;

Then you insert with

INSERT INTO New_Users SELECT * FROM Old_Users GROUP BY ID;

But you can not do it in one statement.

We don't stop or kill a thread rather we do Thread.currentThread().isInterrupted().

public class Task1 implements Runnable {
    public void run() {
            while (!Thread.currentThread().isInterrupted()) {
                       ................
                       ................
                       ................
                       ................
           }
    }
}

in main we will do like this:

Thread t1 = new Thread(new Task1());
t1.start();
t1.interrupt();

I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:

HKEY_LOCAL_MACHINE\SOFTWARE\Python

to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python

Worked for me

solution found at the address below so credits should go there: http://effbot.slinkset.com/items/Adding_Python_Information_to_the_Windows_Registry

You have to replace YourID and value="3" for your current ones.

$(document).ready(function() {_x000D_
  $('#YourID option[value="3"]').attr("selected", "selected");_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script>_x000D_
<select id="YourID">_x000D_
  <option value="1">A</option>_x000D_
  <option value="2">B</option>_x000D_
  <option value="3">C</option>_x000D_
  <option value="4">D</option>_x000D_
</select>

and value="3" for your current ones.

$('#YourID option[value="3"]').attr("selected", "selected");

<select id="YourID" >
<option value="1">A </option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
</select>

For some reason Richard's solution didn't work on my end (insertAdjacentText failed with an exception). This however seems to work:

HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = webBrowser1.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "function sayHello() { alert('hello') }";
head.AppendChild(scriptEl);
webBrowser1.Document.InvokeScript("sayHello");

This answer explains how to get the IHTMLScriptElement interface into your project.

In the latest version of Pandas there is an easy way to do exactly this. Column names (which are strings) can be sliced in whatever manner you like.

columns = ['b', 'c']
df1 = pd.DataFrame(df, columns=columns)

<c:choose>
<c:when test="${not empty userid and userid ne null}">
      <sql:query dataSource="${dbsource}" var="usersql">
                SELECT * FROM newuser WHERE ID = ?;
                <sql:param value="${param.userid}" />
      </sql:query>
 </c:when>
 <c:otherwise >
       <sql:query dataSource="${dbsource}" var="usersql">
                 SELECT * FROM newuser WHERE username = ?;
                 <sql:param value="${param.username}" />
       </sql:query>                              
  </c:otherwise>

Although bash has a return statement, the only thing you can specify with it is the function's own exit status (a value between 0 and 255, 0 meaning "success"). So return is not what you want.

You might want to convert your return statement to an echo statement - that way your function output could be captured using $() braces, which seems to be exactly what you want.

Here is an example:

function fun1(){
  echo 34
}

function fun2(){
  local res=$(fun1)
  echo $res
}

Another way to get the return value (if you just want to return an integer 0-255) is $?.

function fun1(){
  return 34
}

function fun2(){
  fun1
  local res=$?
  echo $res
}

Also, note that you can use the return value to use boolean logic like fun1 || fun2 will only run fun2 if fun1 returns a non-0 value. The default return value is the exit value of the last statement executed within the function.

A 3x3 (multidimensional) array can also be initialized (you have already declared it) like this:

string[,] Tablero =  {
                        { "a", "b", "c" },
                        { "d", "e", "f" }, 
                        { "g", "h", "i"} 
                     };
