This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

Chris Dents' answer has already covered the OPs' question but seeing as this was the top search on google for PowerShell format string as date I thought I'd give a different string example.

If like me, you get the time string like this 20190720170000.000000+000

An important thing to note is you need to use ToUniversalTime() when using [System.Management.ManagementDateTimeConverter] otherwise you get offset times against your input.

PS Code

cls
Write-Host "This example is for the 24hr clock with HH"
Write-Host "ToUniversalTime() must be used when using [System.Management.ManagementDateTimeConverter]"
$my_date_24hr_time   = "20190720170000.000000+000"
$date_format         = "yyyy-MM-dd HH:mm"
[System.Management.ManagementDateTimeConverter]::ToDateTime($my_date_24hr_time).ToUniversalTime();

Use findElement instead of findElements

driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).sendKeys("your value");

OR

driver.findElement(By.id("invoice_supplier_id")).sendKeys("value", "your value");

OR using JavascriptExecutor

WebElement element = driver.findElement(By.xpath("enter the xpath here")); // you can use any locator
 JavascriptExecutor jse = (JavascriptExecutor)driver;
 jse.executeScript("arguments[0].value='enter the value here';", element);

OR

(JavascriptExecutor) driver.executeScript("document.evaluate(xpathExpresion, document, null, 9, null).singleNodeValue.innerHTML="+ DesiredText);

OR (in javascript)

driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).setAttribute("value", "your value")

Hope it will help you :)

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

The new JS API for this is Object.fromEntries(array of tuples), it works with raw arrays and/or Maps

$scope.actions.data.concat is not a function 

same problem with me but i solve the problem by

 $scope.actions.data = [].concat($scope.actions.data , data)

After messing with this for days, my final fix for our issues required two things;

1) We added this line of code to all of our .Net libraries that make out bound api calls to other vendors that had also disabled their SSL v3.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls; // (.Net 4 and below)

2) This is the final and FULL registry changes you will need when you are running ASP.Net 4.0 sites and will need to be slightly changed after you upgrade to ASP.Net 4.5.

After we rebooted the servers - all problems went away after this.

Cut the whole contents in the worksheet using "Ctrl + A" followed by "Ctrl + X" and paste it to a new sheet. Your reference to formulas will remain intact when you cut paste.

Something throws an exception of type std::bad_alloc, indicating that you ran out of memory. This exception is propagated through until main, where it "falls off" your program and causes the error message you see.

Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h looks like a syntax error.

Use subquery

If you don't mind a third party dependency, there is a class named Collectors2 in Eclipse Collections which contains methods returning Collectors for summing and summarizing BigDecimal and BigInteger. These methods take a Function as a parameter so you can extract a BigDecimal or BigInteger value from an object.

List<BigDecimal> list = mList(
        BigDecimal.valueOf(0.1),
        BigDecimal.valueOf(1.1),
        BigDecimal.valueOf(2.1),
        BigDecimal.valueOf(0.1));

BigDecimal sum =

Assert.assertEquals(BigDecimal.valueOf(3.4), statistics.getSum());
Assert.assertEquals(BigDecimal.valueOf(0.1), statistics.getMin());
Assert.assertEquals(BigDecimal.valueOf(2.1), statistics.getMax());
Assert.assertEquals(BigDecimal.valueOf(0.85), statistics.getAverage());

The DEFAULT clause specifies a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression. This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE. The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column

Just in case anyone arrives here and was hoping for VB (I did, and I didn't enter c# as a search term), here's the basics of the first response..

Public Shared Function ConvertDataTableToHTML(dt As DataTable) As String
    Dim html As String = "<table>"
    html += "<tr>"
    For i As Integer = 0 To dt.Columns.Count - 1
        html += "<td>" + System.Web.HttpUtility.HtmlEncode(dt.Columns(i).ColumnName) + "</td>"
    Next
    html += "</tr>"
    For i As Integer = 0 To dt.Rows.Count - 1
        html += "<tr>"
        For j As Integer = 0 To dt.Columns.Count - 1
            html += "<td>" + System.Web.HttpUtility.HtmlEncode(dt.Rows(i)(j).ToString()) + "</td>"
        Next
        html += "</tr>"
    Next
    html += "</table>"
    Return html
End Function

In your code $this->uri->segment(3) refers to the pagination offset which you use in your query. According to your $config['base_url'] = base_url().'index.php/papplicant/viewdeletedrecords/' ;, $this->uri->segment(3) i.e segment 3 refers to the offset. The first segment is the controller, second is the method, there after comes the parameters sent to the controllers as segments.

I was just having this issue with my own program. I turned out that the value I was searching for was not in my reference table. I fixed my reference table, and then the error went away.

The best way to handle this would be to terminate your infinite loop with a proper condition.

But since you asked for the exception handling:

Try to use two catches. Your EOFException is expected, so there seems to be no problem when it occures. Any other exception should be handled.

...
} catch (EOFException e) {
   // ... this is fine
} catch(IOException e) {
    // handle exception which is not expected
    e.printStackTrace(); 
}

The reason you don't have permissions to open file is because you didn't grant other apps to open or view the file on your intent. To grant other apps to open the downloaded file, include the flag(as shown below): FLAG_GRANT_READ_URI_PERMISSION

Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.setDataAndType(getUriFromFile(localFile), "application/pdf");
browserIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION|
Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(browserIntent);

And for function:

getUriFromFile(localFile)

private Uri getUriFromFile(File file){
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
        return Uri.fromFile(file);
    }else {
        return FileProvider.getUriForFile(itemView.getContext(), itemView.getContext().getApplicationContext().getPackageName() + ".provider", file);
    }
}

if tableFields is an array , you can loop through elements as following :

for (item in tableFields); {
     console.log(tableFields[item]);
}

by the way i saw a logical error in you'r code.just remove ; from end of for loop

right here :

for (item in tableFields); { .

this will cause you'r loop to do just nothing.and the following line will be executed only once :

// Do stuff

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

And with the new string formatting method...

f = open('{0}.csv'.format(name), 'wb')

You can use CREATE SYNONYM to remote object.

It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?

Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:

UPDATE INVOICE
   SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
     , INV_TOTAL    = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)     
WHERE INV_ID = I_INV_ID;

        

Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.

Here is a modification for the prev. answer. The main difference is when the user is not authenticated, it uses the original "HandleUnauthorizedRequest" method to redirect to login page:

   protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {

        if (filterContext.HttpContext.User.Identity.IsAuthenticated) {

            filterContext.Result = new RedirectToRouteResult(
                        new RouteValueDictionary(
                            new
                            {
                                controller = "Account",
                                action = "Unauthorised"
                            })
                        );
        }
        else
        {
             base.HandleUnauthorizedRequest(filterContext);
        }
    }

This isn't exactly intuitive, but you cannot Redim(VB6 Ref) an array if you dimmed it with dimensions. Exact quote from linked page is:

The ReDim statement is used to size or resize a dynamic array that has already been formally declared using a Private, Public, or Dim statement with empty parentheses (without dimension subscripts).

In other words, instead of dim invoices(10,0)

You should use

Dim invoices()
Redim invoices(10,0)

Then when you ReDim, you'll need to use Redim Preserve (10,row)

Warning: When Redimensioning multi-dimensional arrays, if you want to preserve your values, you can only increase the last dimension. I.E. Redim Preserve (11,row) or even (11,0) would fail.

I have been battling this for a about a week. I'm trying to learn Java on Netbeans IDE and so naturally I get the combo file straight from Oracle. Which is a package of the JDK and the Netbeans IDE together in a tar file located here.

located http://www.oracle.com/technetwork/java/javase/downloads/index.html file name JDK 8u25 with NetBeans 8.0.1

after installing them (or so I thought) I would make/compile a simple program like "hello world" and that would spit out a jar file that you would be able to run in a terminal. Keep in mind that the program ran in the Netbeans IDE.

I would end up with this error: java.lang.UnsupportedClassVersionError:

Even though I ran the file from oracle website I still had the old version of the Java runtime which was not compatible to run my jar file which was compiled with the new java runtime.

After messing with stuff that was mostly over my head from setting Paths to editing .bashrc with no remedy.

I came across a solution that was easy enough for even me. I have come across something that auto installs java and configures it on your system and it works with the latest 1.8.*

One of the steps is adding a PPA wasn't sure about this at first but seems ok as it has worked for me

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

domenic@domenic-AO532h ~ $ java -version java version "1.8.0_25" Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Java HotSpot(TM) Server VM (build 25.25-b02, mixed mode)

I think it also configures the browser java as well.

I hope this helps others.

One of your tables has the same column name's which brings a confusion in the query as to which columns of the tables are you referring to. Copy this code and run it.

SELECT 
    v.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount
FROM Vendors AS v
JOIN Invoices AS i ON (v.VendorID = .VendorID)
JOIN InvoiceLineItems AS iL ON (i.InvoiceID = iL.InvoiceID)
WHERE  
    I.InvoiceID IN
        (SELECT iL.InvoiceSequence 
         FROM InvoiceLineItems
         WHERE iL.InvoiceSequence > 1)
ORDER BY 
    V.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount

WITH CTE_DocTotal (DocTotal, InvoiceNumber)
AS
(
    SELECT  InvoiceNumber,
            SUM(Sale + VAT) AS DocTotal
    FROM    PEDI_InvoiceDetail
    GROUP BY InvoiceNumber
)    
UPDATE PEDI_InvoiceDetail
SET PEDI_InvoiceDetail.DocTotal = CTE_DocTotal.DocTotal
FROM CTE_DocTotal
INNER JOIN PEDI_InvoiceDetail ON ...

You can do this using cross apply

SELECT c.BalanceDue AS BalanceDue
FROM Invoices
cross apply (select (InvoiceTotal - PaymentTotal - CreditTotal) as BalanceDue) as c
WHERE  c.BalanceDue  > 0;

For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:

 db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.

The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:

 db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:

db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
               {$inc : {total : 1 , "items.$.price" : 1}} ,
               false ,
               true);

One of the reasons your 1M test ran quicker is likely because the temp tables are entirely in memory and would only go to disk if your server experiences memory pressure. You can either re-craft your query to remove the order by, add a good clustered index and covering index(es) as previously mentioned, or query the DMV to check for IO pressure to see if hardware related.

If you set the server output in ON mode before the entire code, it works, otherwise put_line() will not work. Try it!

The code is,

set serveroutput on;
CREATE OR REPLACE PROCEDURE PROC1(invoicenr IN NUMBER, amnt OUT NUMBER)
AS BEGIN
SELECT AMOUNT INTO amnt FROM INVOICE WHERE INVOICE_NR = invoicenr;
END;

And then call the function as it is:

DECLARE
amount NUMBER;
BEGIN
PROC1(1000001, amount);
dbms_output.put_line(amount);
END;

Following are few libraries to create PDF with Java:

1. iText
2. Apache PDFBox
3. BFO

I have used iText for genarating PDF's with a little bit of pain in the past.

Or you can try using FOP: FOP is an XSL formatter written in Java. It is used in conjunction with an XSLT transformation engine to format XML documents into PDF.

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

Every InvoiceItem must have an Invoice attached to it because of the not-null="true" in the many-to-one mapping.

So the basic idea is you need to set up that explicit relationship in code. There are many ways to do that. On your class I see a setItems method. I do NOT see an addInvoiceItem method. When you set items, you need to loop through the set and call item.setInvoice(this) on all of the items. If you implement an addItem method, you need to do the same thing. Or you need to otherwise set the Invoice of every InvoiceItem in the collection.

I had the "same" problem because I was writting

@GeneratedValue(strategy = GenerationType.IDENTITY)

I deleted that line due that I do not need it at the moment, I was testing with objects and so. I think it is <generator class="native" /> in your case

I do not have any controller and my API is not being accessed, it is only for testing (at the moment).

I'm aware the question is php oriented, but the best way to redirect a POST request is probably using .htaccess, ie:

RewriteEngine on
RewriteCond %{REQUEST_URI} string_to_match_in_url
RewriteCond %{REQUEST_METHOD} POST
RewriteRule ^(.*)$ https://domain.tld/$1 [L,R=307]

Explanation:

By default, if you want to redirect request with POST data, browser redirects it via GET with 302 redirect. This also drops all the POST data associated with the request. Browser does this as a precaution to prevent any unintentional re-submitting of POST transaction.

But what if you want to redirect anyway POST request with it’s data? In HTTP 1.1, there is a status code for this. Status code 307 indicates that the request should be repeated with the same HTTP method and data. So your POST request will be repeated along with it’s data if you use this status code.

SRC

If you've been doing performance tuning, you might have removed mod_dir. Try putting it back and that might fix your issue.

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

Unfortunately, PostgreSQL supports neither MERGE nor ON DUPLICATE KEY UPDATE, so you'll have to do it in two statements:

UPDATE  invoices
SET     billed = 'TRUE'
WHERE   invoices = '12345'

INSERT
INTO    invoices (invoiceid, billed)
SELECT  '12345', 'TRUE'
WHERE   '12345' NOT IN
        (
        SELECT  invoiceid
        FROM    invoices
        )

You can wrap it into a function:

CREATE OR REPLACE FUNCTION fn_upd_invoices(id VARCHAR(32), billed VARCHAR(32))
RETURNS VOID
AS
$$
        UPDATE  invoices
        SET     billed = $2
        WHERE   invoices = $1;

        INSERT
        INTO    invoices (invoiceid, billed)
        SELECT  $1, $2
        WHERE   $1 NOT IN
                (
                SELECT  invoiceid
                FROM    invoices
                );
$$
LANGUAGE 'sql';

and just call it:

SELECT  fn_upd_invoices('12345', 'TRUE')

I'm using the following function for that; it's an adaptation from one of the man entries in the fputscsv comments. And you'll probably want to flatten that array; not sure what happens if you pass in a multi-dimensional one.

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

The error implies that this subquery is returning more than 1 row:

(Select Supplier_Item.Price from Supplier_Item,orderdetails,Supplier where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

You probably don't want to include the orderdetails and supplier tables in the subquery, because you want to reference the values selected from those tables in the outer query. So I think you want the subquery to be simply:

(Select Supplier_Item.Price from Supplier_Item where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

I suggest you read up on correlated vs. non-correlated subqueries.

I usually just remove all quotes from my variables with:

set var=%var:"=%

And then apply them again wherever I need them e.g.:

echo "%var%"

In your example, because you use CurrentDB to execute your INSERT you've made it harder for yourself. Instead, this will work:

  Dim query As String
  Dim newRow As Long  ' note change of data type
  Dim db As DAO.Database

  query = "INSERT INTO InvoiceNumbers (date) VALUES (" & NOW() & ");"
  Set db = CurrentDB
  db.Execute(query)
  newRow = db.OpenRecordset("SELECT @@IDENTITY")(0)
  Set db = Nothing

I used to do INSERTs by opening an AddOnly recordset and picking up the ID from there, but this here is a lot more efficient. And note that it doesn't require ADO.

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

I just had the same problem and...

declare @userId uniqueidentifier
set @userId = (select top 1 UserId from aspnet_Users)

or even shorter:

declare @userId uniqueidentifier
SELECT TOP 1 @userId = UserId FROM aspnet_Users

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

Slight variation, main difference being to set the primary key field ("varname") to null, which produces a warning but works. By setting the primary key to null, the auto-increment works when inserting the record in the last statement.

This code also cleans up previous attempts, and can be run more than once without problems:

DELETE FROM `tbl` WHERE varname="primary key value for new record";
DROP TABLE tmp;
CREATE TEMPORARY TABLE tmp SELECT * FROM `tbl` WHERE varname="primary key value for old record";
UPDATE tmp SET varname=NULL;
INSERT INTO `tbl` SELECT * FROM tmp;

Public Sub LinqToSqlJoin07()
Dim q = From e In db.Employees _
        Group Join o In db.Orders On e Equals o.Employee Into ords = Group _
        From o In ords.DefaultIfEmpty _
        Select New With {e.FirstName, e.LastName, .Order = o}

ObjectDumper.Write(q) End Sub

Check http://msdn.microsoft.com/en-us/vbasic/bb737929.aspx

you can follow this link to know more about How to convert a string/number into number/float/decimal in PHP. HERE IS WHAT THIS LINK SAYS...

Method 1: Using number_format() Function. The number_format() function is used to convert a string into a number. It returns the formatted number on success otherwise it gives E_WARNING on failure.

$num = "1000.314"; 

//Convert string in number using  
//number_format(), function 
echo number_format($num), "\n"; 

//Convert string in number using  
//number_format(), function 
echo number_format($num, 2); 

Method 2: Using type casting: Typecasting can directly convert a string into a float, double, or integer primitive type. This is the best way to convert a string into a number without any function.

// Number in string format 
$num = "1000.314"; 

// Type cast using int 
echo (int)$num, "\n"; 

// Type cast using float 
echo (float)$num, "\n"; 

// Type cast using double 
echo (double)$num; 

Method 3: Using intval() and floatval() Function. The intval() and floatval() functions can also be used to convert the string into its corresponding integer and float values respectively.

// Number in string format 
$num = "1000.314"; 

// intval() function to convert  
// string into integer 
echo intval($num), "\n"; 

// floatval() function to convert 
// string to float 
echo floatval($num); 

Method 4: By adding 0 or by performing mathematical operations. The string number can also be converted into an integer or float by adding 0 with the string. In PHP, performing mathematical operations, the string is converted to an integer or float implicitly.

// Number into string format 
$num = "1000.314"; 

// Performing mathematical operation  
// to implicitly type conversion 
echo $num + 0, "\n"; 

// Performing mathematical operation  
// to implicitly type conversion 
echo $num + 0.0, "\n"; 

// Performing mathematical operation  
// to implicitly type conversion 
echo $num + 0.1;

So this isn't what the requester was asking for but it is the answer to "SQL selecting rows by most recent date".

Split the string (into an array) by <space>, and then take the first 20 elements of that array.

You can extract text by area in PDFBox. See the ExtractByArea.java example file, in the pdfbox-examples artifact if you're using Maven. A snippet looks like

   PDFTextStripperByArea stripper = new PDFTextStripperByArea();
   stripper.setSortByPosition( true );
   Rectangle rect = new Rectangle( 464, 59, 55, 5);
   stripper.addRegion( "class1", rect );
   stripper.extractRegions( page );
   String string = stripper.getTextForRegion( "class1" );

The problem is getting the coordinates in the first place. I've had success extending the normal TextStripper, overriding processTextPosition(TextPosition text) and printing out the coordinates for each character and figuring out where in the document they are.

But there's a much simpler way, at least if you're on a Mac. Open the PDF in Preview, ?I to show the Inspector, choose the Crop tab and make sure the units are in Points, from the Tools menu choose Rectangular selection, and select the area of interest. If you select an area, the inspector will show you the coordinates, which you can round and feed into the Rectangle constructor arguments. You just need to confirm where the origin is, using the first method.

I am improving upon supercat's answer. I guess the following can also be done:

class Sample
{
    private readonly int _intField;
    public int IntProperty
    {
        get { return _intField; }
    }

    void setupStuff(ref int intField, int newValue)
    {
        //Do some stuff here based upon the necessary initialized variables.
        intField = newValue;
    }

    public Sample(string theIntAsString, bool? doStuff = true)
    {
        //Initialization of some necessary variables.
        //==========================================
        int i = int.Parse(theIntAsString);
        // ................
        // .......................
        //==========================================

        if (!doStuff.HasValue || doStuff.Value == true)
           setupStuff(ref _intField,i);
    }

    public Sample(int theInt): this(theInt, false) //"false" param to avoid setupStuff() being called two times
    {
        setupStuff(ref _intField, theInt);
    }
}

Check out our jQuery-ClearSearch plugin. It's a configurable jQuery plugin - adapting it to your needs by styling the input field is straightforward. Just use it as follows:

<input class="clearable" type="text" placeholder="search">

<script type="text/javascript">
    $('.clearable').clearSearch();
</script>

? Example: http://jsfiddle.net/wldaunfr/FERw3/

Every method (other than a constructor) must have a return type.

public double diameter(){...

You can use the regex "\W".This matches any non-word character.The required line would be:

String[] tokens=pdfName.split("\\W");

This is not possible now, but there is a work around. You can engage with the user in the public realm and ask them to send you private messages, but you can't send private messages back, only public ones. Of course, this all depends on if the user gives you the correct permissions.

If you have given permission to access a person's friends, you can then theoretically post on that users wall with references to each one of the friends, asking them to publicly interact with you and then potentially privately message you.

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

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

So my final code looks like this ($bp_gr1' are strings like 1,2,3):

UPDATE TAB1
SET    BUDGPOST_GR1 =
          CASE
             WHEN ( BUDGPOST IN (SELECT     REGEXP_SUBSTR ( '$BP_GR1',
                                                            '[^,]+',
                                                            1,
                                                            LEVEL )
                                 FROM       DUAL
                                 CONNECT BY REGEXP_SUBSTR ( '$BP_GR1',

Is there a way to make it run faster?

getText is a member of the your Activity so it must be called when "this" exists. Your static variable is initialized when your class is loaded before your Activity is created.

Since you want the variable to be initialized from a Resource string then it cannot be static. If you want it to be static you can initialize it with the String value.

Just try this, it explains it pretty much itself. You can't create a view with an ORDER BY except if...

CREATE VIEW v_Test
         AS
           SELECT name
             FROM sysobjects
         ORDER BY name
        GO

Msg 1033, Level 15, State 1, Procedure TestView, Line 5 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

Your first attempt was close. Here is the simplistic approach using your idea.

file="somefileondisk"
lines=`cat $file`
for line in $lines; do
        echo "$line"
done

Just change sizeof with strlen.

Like this:

char *source = "This is an example.";
int i;

for (i = 0; i < strlen(source); i++){

    printf("%c", source[i]);

}

According to your CSS file path, I will suppose it is at the same directory with your HTML page, you have to change the url as follows:

body { background: url(img/debut_dark.png) repeat 0 0; }

It does have to be wrapped in an <xsl:choose> since it's a when. And lowercase the "and".

<xsl:choose>
   <xsl:when test="4 &lt; 5 and 1 &lt; 2" >
   <!-- do something -->
   </xsl:when>
   <xsl:otherwise>
   <!-- do something else -->
   </xsl:otherwise>
</xsl:choose>

Thanks to the way you can index and subset a pandas dataframe, a very easy way to extract a single column from a csv file into a variable is:

myVar = pd.read_csv('YourPath', sep = ",")['ColumnName']

A few things to consider:

The snippet above will produce a pandas Series and not dataframe. The suggestion from ayhan with usecols will also be faster if speed is an issue. Testing the two different approaches using %timeit on a 2122 KB sized csv file yields 22.8 ms for the usecols approach and 53 ms for my suggested approach.

And don't forget import pandas as pd

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

The following works perfectly:-

if(isset($_POST['signup'])){
$username=mysqli_real_escape_string($connect,$_POST['username']);
$email=mysqli_real_escape_string($connect,$_POST['email']);
$pass1=mysqli_real_escape_string($connect,$_POST['pass1']);
$pass2=mysqli_real_escape_string($connect,$_POST['pass2']);

Now, the $connect is my variable containing my connection to the database. You only left out the connection variable. Include it and it shall work perfectly.

Work with checkboxes using observables

You could even choose to use a behaviourSubject to utilize the power of observables so you can start a certain chain of reaction starting at the isChecked$ observable.

In your component.ts:

public isChecked$ = new BehaviorSubject(false);
toggleChecked() {
  this.isChecked$.next(!this.isChecked$.value)
}

In your template

<input type="checkbox" [checked]="isChecked$ | async" (change)="toggleChecked()">

If it's just for passing values between pages and you only require it for the one request. Use Context.

Context

The Context object holds data for a single user, for a single request, and it is only persisted for the duration of the request. The Context container can hold large amounts of data, but typically it is used to hold small pieces of data because it is often implemented for every request through a handler in the global.asax. The Context container (accessible from the Page object or using System.Web.HttpContext.Current) is provided to hold values that need to be passed between different HttpModules and HttpHandlers. It can also be used to hold information that is relevant for an entire request. For example, the IBuySpy portal stuffs some configuration information into this container during the Application_BeginRequest event handler in the global.asax. Note that this only applies during the current request; if you need something that will still be around for the next request, consider using ViewState. Setting and getting data from the Context collection uses syntax identical to what you have already seen with other collection objects, like the Application, Session, and Cache. Two simple examples are shown here:

// Add item to
Context Context.Items["myKey"] = myValue;

// Read an item from the
 Context Response.Write(Context["myKey"]);

http://msdn.microsoft.com/en-us/magazine/cc300437.aspx#S6

Using the above. If you then do a Server.Transfer the data you've saved in the context will now be available to the next page. You don't have to concern yourself with removing/tidying up this data as it is only scoped to the current request.

If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).

If you cannot find it this way, try the menu: View/Properties Window.

Or try the F4 key.

following is the code we eventually created. A breif explanation first. We used a "q_" for the div name wrapped around the radio button question list. Then we had "s_" for any sections. The following code loops through the questions to find the checked value, and then performs a slide action on the relevant section.

var shows_6 = function() {
  var selected = $("#q_7 input:radio:checked").val();
  if (selected == 'Groom') {
    $("#s_6").slideDown();
  } else {
    $("#s_6").slideUp();
  }
};
$('#q_7 input').ready(shows_6);
var shows_7 = function() {
  var selected = $("#q_7 input:radio:checked").val();
  if (selected == 'Bride') {
    $("#s_7").slideDown();
  } else {
    $("#s_7").slideUp();
  }
};
$('#q_7 input').ready(shows_7);
$(document).ready(function() {
  $('#q_7 input:radio').click(shows_6);
  $('#q_7 input:radio').click(shows_7);
});

<div id="q_7" class='question '><label>Who are you?</label> 
  <p>
    <label for="ctl00_ctl00_ContentMainPane_Body_ctl00_ctl00_chk_0">Bride</label>
    <input id="ctl00_ctl00_ContentMainPane_Body_ctl00_ctl00_chk_0" type="radio" name="ctl00$ctl00$ContentMainPane$Body$ctl00$ctl00$chk" value="Bride" />
  </p> 
  <p>
    <label for="ctl00_ctl00_ContentMainPane_Body_ctl00_ctl00_chk_1">Groom</label>
    <input id="ctl00_ctl00_ContentMainPane_Body_ctl00_ctl00_chk_1" type="radio" name="ctl00$ctl00$ContentMainPane$Body$ctl00$ctl00$chk" value="Groom" />
  </p> 

</div> 

The following allows us to make the question mandatory...

<script type="text/javascript"> 
var mandatory_q_7 = function() {
  var selected = $("#q_7 input:radio:checked").val();
  if (selected != '') {
    $("#q_7").removeClass('error');
  }
};
$(document).ready(function() {
    $('#q_7 input:radio').click(function(){mandatory_q_7();});
});
</script> 

Here's an example of the actual show / hide layer

<div class="section" id="s_6"> 
    <h2>Attire</h2> 
    ...
</div>

df.gdp = df.gdp.shift(-1) ## shift up
df.gdp.drop(df.gdp.shape[0] - 1,inplace = True) ## removing the last row

Have gone through this issue, below is my conclusion to this issue and my solution.

According to the CORS strategy (highly recommend you read about it) You can't just force the browser to stop sending OPTIONS request if it thinks it needs to.

There are two ways you can work around it:

1. Make sure your request is a "simple request"
2. Set Access-Control-Max-Age for the OPTIONS request

Simple request

A simple cross-site request is one that meets all the following conditions:

The only allowed methods are:

• GET
• HEAD
• POST

Apart from the headers set automatically by the user agent (e.g. Connection, User-Agent, etc.), the only headers which are allowed to be manually set are:

• Accept
• Accept-Language
• Content-Language
• Content-Type

The only allowed values for the Content-Type header are:

• application/x-www-form-urlencoded
• multipart/form-data
• text/plain

A simple request will not cause a pre-flight OPTIONS request.

Set a cache for the OPTIONS check

You can set a Access-Control-Max-Age for the OPTIONS request, so that it will not check the permission again until it is expired.

Access-Control-Max-Age gives the value in seconds for how long the response to the preflight request can be cached for without sending another preflight request.

Limitation Noted

• For Chrome, the maximum seconds for Access-Control-Max-Age is 600 which is 10 minutes, according to chrome source code
• Access-Control-Max-Age only works for one resource every time, for example, GET requests with same URL path but different queries will be treated as different resources. So the request to the second resource will still trigger a preflight request.

How about useing Array.ConstrainedCopy:

int[] ArrayOne = new int[8] {1,2,3,4,5,6,7,8};
int[] ArrayTwo = new int[5];
Array.ConstrainedCopy(ArrayOne, 3, ArrayTwo, 0, 7-3);

Below is my original post. It will not work

You could use Array.CopyTo:

int[] ArrayOne = new int[8] {1,2,3,4,5,6,7,8};
int[] ArrayTwo = new int[5];
ArrayOne.CopyTo(ArrayTwo,3); //starts copy at index=3 until it reaches end of
                             //either array

you need to put a textvariable in it, so you can use set() and get() method :

var=StringVar()
x= Entry (root,textvariable=var)

The EASIEST way to get a very usable text file is to download S3 Browser http://s3browser.com/ and use the Web URLs Generator to produce a list of complete link paths. It is very handy and involves about 3 clicks.

-Browse to Folder
-Select All
-Generate Urls

Best of luck to you.

Um, lots.

There are several parameters here. The specific VM, plus there are usually run-time parameters on the VM as well. That's somewhat driven by the operating system: what support does the underlying OS have for threads and what limitations does it put on them? If the VM actually uses OS-level threads at all, the good old red thread/green thread thing.

What "support" means is another question. If you write a Java program that is just something like

   class DieLikeADog {
         public static void main(String[] argv){
             for(;;){
                new Thread(new SomeRunaable).start();
             }
         }
    }

(and don't complain about little syntax details, I'm on my first cup of coffee) then you should certainly expect to get hundreds or thousands of threads running. But creating a Thread is relatively expensive, and scheduler overhead can get intense; it's unclear that you could have those threads do anything useful.

Update

Okay, couldn't resist. Here's my little test program, with a couple embellishments:

public class DieLikeADog {
    private static Object s = new Object();
    private static int count = 0;
    public static void main(String[] argv){
        for(;;){
            new Thread(new Runnable(){
                    public void run(){
                        synchronized(s){
                            count += 1;
                            System.err.println("New thread #"+count);
                        }
                        for(;;){
                            try {
                                Thread.sleep(1000);
                            } catch (Exception e){
                                System.err.println(e);
                            }
                        }
                    }
                }).start();
        }
    }
}

On OS/X 10.5.6 on Intel, and Java 6 5 (see comments), here's what I got

I had this same error in an MVC 4 application using Razor. In an attempt to clean up the web.config files, I removed the two webpages: configuration values:

<appSettings>
  <add key="webpages:Version" value="2.0.0.0" />
  <add key="webpages:Enabled" value="false" />

Once I restored these configuration values, the pages would compile correctly and the errors regarding the .Partial() extension method disappeared.

What worked for me is

svn revert --depth infinity deletedDir

Do not forget to clear the cache after updating the external_url param in /etc/gitlab/gitlab.rb, otherwise your existing project clone URLs will still be showing your old host name.

A simple 3 step process to change the hostname is as follows

• update the external_url param in /etc/gitlab/gitlab.rb
• sudo gitlab-ctl reconfigure
• sudo gitlab-ctl restart
• sudo gitlab-rake cache:clear

Ref:

https://forum.gitlab.com/t/clone-url-wont-change/21692/6

Send your data with SESSION rather than post.

session_start();
$_SESSION['foo'] = "bar";

On the page where you recieve the request, if you absolutely need POST data (some weird logic), you can do this somwhere at the beginning:

$_POST['foo'] = $_SESSION['foo'];

The post data will be valid just the same as if it was sent with POST.

Then destroy the session (or just unset the fields if you need the session for other purposes).

It is important to destroy a session or unset the fields, because unlike POST, SESSION will remain valid until you explicitely destroy it or until the end of browser session. If you don't do it, you can observe some strange results. For example: you use sesson for filtering some data. The user switches the filter on and gets filtered data. After a while, he returns to the page and expects the filter to be reset, but it's not: he still sees filtered data.

The normal way of doing it is:

• You get the users from the database in controller.
• You send a collection of users to the View
• In the view to loop the list of users building the list.

You don't need a JsonResult or jQuery for this.

The best version I could think while not using copy would be:

from itertools import chain
x = {'a':1, 'b': 2}
y = {'b':10, 'c': 11}
dict(chain(x.iteritems(), y.iteritems()))

It's faster than dict(x.items() + y.items()) but not as fast as n = copy(a); n.update(b), at least on CPython. This version also works in Python 3 if you change iteritems() to items(), which is automatically done by the 2to3 tool.

Personally I like this version best because it describes fairly good what I want in a single functional syntax. The only minor problem is that it doesn't make completely obvious that values from y takes precedence over values from x, but I don't believe it's difficult to figure that out.

I had the same issue : behind a corporate proxy with auth at work, I couldn't have pip work, as well as Sublime Text 2 (well, it worked with custom setup of my proxy settings). For pip (and I'll try that on git), I solved it installing cntlm proxy. It was very simple to configure :

1. Edit cntlm.ini
2. Edit "Username", "Domain", "Password" fields
3. Add a "Proxy" line, with your proxy settings : server:port
4. Make sure the line "NoProxy" integrates "localhost" (like that by default)
5. Note the default port : 3128
6. Save and that's it.

To test that works, just launch a new command line tool, and try :

pip install django --proxy=localhost:3128

That worked for me. Hope this will help you.

If anybody else had a problem with best answer's solution (including disabling foreign keys), here is another solution from me:

-- CLEAN DB
USE [DB_NAME]
    EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
    EXEC sp_MSForEachTable 'DELETE FROM ?'

    DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR
    SET @Cursor = CURSOR FAST_FORWARD FOR

    SELECT DISTINCT sql = 'ALTER TABLE [' + tc2.TABLE_NAME + '] DROP [' + rc1.CONSTRAINT_NAME + ']'
    FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1
    LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc2 ON tc2.CONSTRAINT_NAME =rc1.CONSTRAINT_NAME
    OPEN @Cursor FETCH NEXT FROM @Cursor INTO @Sql
    WHILE (@@FETCH_STATUS = 0)
      BEGIN
        Exec SP_EXECUTESQL @Sql
        FETCH NEXT 
        FROM @Cursor INTO @Sql
      END
    CLOSE @Cursor DEALLOCATE @Cursor
    GO

    EXEC sp_MSForEachTable 'DROP TABLE ?'
    GO

    EXEC sp_MSForEachTable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL'

Before going into Bucketing, we need to understand what Partitioning is. Let us take the below table as an example. Note that I have given only 12 records in the below example for beginner level understanding. In real-time scenarios you might have millions of records.

PARTITIONING
---------------------
Partitioning is used to obtain performance while querying the data. For example, in the above table, if we write the below sql, it need to scan all the records in the table which reduces the performance and increases the overhead.

select * from sales_table where product_id='P1'

To avoid full table scan and to read only the records related to product_id='P1' we can partition (split hive table's files) into multiple files based on the product_id column. By this the hive table's file will be split into two files one with product_id='P1' and other with product_id='P2'. Now when we execute the above query, it will scan only the product_id='P1' file.

../hive/warehouse/sales_table/product_id=P1
../hive/warehouse/sales_table/product_id=P2

The syntax for creating the partition is given below. Note that we should not use the product_id column definition along with the non-partitioned columns in the below syntax. This should be only in the partitioned by clause.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10))

Cons : We should be very careful while partitioning. That is, it should not be used for the columns where number of repeating values are very less (especially primary key columns) as it increases the number of partitioned files and increases the overhead for the Name node.

BUCKETING
------------------
Bucketing is used to overcome the cons that I mentioned in the partitioning section. This should be used when there are very few repeating values in a column (example - primary key column). This is similar to the concept of index on primary key column in the RDBMS. In our table, we can take Sales_Id column for bucketing. It will be useful when we need to query the sales_id column.

Below is the syntax for bucketing.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10)) Clustered by(Sales_Id) into 3 buckets

Here we will further split the data into few more files on top of partitions.

Since we have specified 3 buckets, it is split into 3 files each for each product_id. It internally uses modulo operator to determine in which bucket each sales_id should be stored. For example, for the product_id='P1', the sales_id=1 will be stored in 000001_0 file (ie, 1%3=1), sales_id=2 will be stored in 000002_0 file (ie, 2%3=2),sales_id=3 will be stored in 000000_0 file (ie, 3%3=0) etc.

It's 2012, the post-PC era is here, and we still have to struggle with something as basic as this. This ought to be very simple.

Until such time as that dream is fulfilled, here's the best way to do this, cross-browser: use a combination of the input and onpropertychange events, like so:

var area = container.querySelector('textarea');
if (area.addEventListener) {
  area.addEventListener('input', function() {
    // event handling code for sane browsers
  }, false);
} else if (area.attachEvent) {
  area.attachEvent('onpropertychange', function() {
    // IE-specific event handling code
  });
}

The input event takes care of IE9+, FF, Chrome, Opera and Safari, and onpropertychange takes care of IE8 (it also works with IE6 and 7, but there are some bugs).

The advantage of using input and onpropertychange is that they don't fire unnecessarily (like when pressing the Ctrl or Shift keys); so if you wish to run a relatively expensive operation when the textarea contents change, this is the way to go.

Now IE, as always, does a half-assed job of supporting this: neither input nor onpropertychange fires in IE when characters are deleted from the textarea. So if you need to handle deletion of characters in IE, use keypress (as opposed to using keyup / keydown, because they fire only once even if the user presses and holds a key down).

Source: http://www.alistapart.com/articles/expanding-text-areas-made-elegant/

EDIT: It seems even the above solution is not perfect, as rightly pointed out in the comments: the presence of the addEventListener property on the textarea does not imply you're working with a sane browser; similarly the presence of the attachEvent property does not imply IE. If you want your code to be really air-tight, you should consider changing that. See Tim Down's comment for pointers.

<div class="button_style">
This is your button value
</div>

.button_style{   
background-color: Transparent;
border: none;             /* Your can add different style/properties of button Here*/
cursor:pointer;    
}

Definitely, there is no solution with pure HTML to submit a form with a link (a) tag. The standard HTML accepts only buttons or images. As some other collaborators have said, one can simulate the appearance of a link using a button, but I guess that's not the purpose of the question.

IMHO, I believe that the proposed and accepted solution does not work.

I have tested it on a form and the browser didn't find the reference to the form.

So it is possible to solve it using a single line of JavaScript, using this object, which references the element being clicked, which is a child node of the form, that needs to be submitted. So this.parentNode is the form node. After it's just calling submit() method in that form. It's no necessary research from whole document to find the right form.

<form action="http://www.greatsolutions.com.br/indexint.htm"                   
   method="get">
    <h3> Enter your name</h3>
    First Name <input type="text"  name="fname"  size="30"><br>
    Last Name <input type="text" name="lname" size="30"><br>
    <a href="#" onclick="this.parentNode.submit();"> Submit here</a>
</form>

Suppose that I enter with my own name:

I've used get in form method attribute because it's possible to see the right parameters in the URL at loaded page after submit.

http://www.greatsolutions.com.br/indexint.htm?fname=Paulo&lname=Buchsbaum

This solution obviously applies to any tag that accepts the onclick event or some similar event.

this is a excellent choice to recover the context together with event variable (available in all major browsers and IE9 onwards) that can be used directly or passed as an argument to a function.

In this case, replace the line with a tag by the line below, using the property target, that indicates the element that has started the event.

<a href="#" onclick="event.target.parentNode.submit();"> Submit here</a>

Here is a pure CSS solution based on the current infowindow example on google:

https://developers.google.com/maps/documentation/javascript/examples/infowindow-simple

#map *{
  overflow: visible;
}
#content{
  display: block;
  position: absolute;
  bottom: -8px;
  left: -20px;
  background-color: white;
  z-index: 10001;
}

This is a quick solution that will work well for small info windows. Don't forget to up vote if it helps :P

I would suggest you try this jQuery plugin print element

It can let you just print the element you selected.

Different Environments

Typically, software will run in different environments:

• development
• testing
• staging
• production

Different Dependencies in Different Environments

The dependencies which are declared in the require section of composer.json are typically dependencies which are required for running an application or a package in

• staging
• production

environments, whereas the dependencies declared in the require-dev section are typically dependencies which are required in

• developing
• testing

environments.

For example, in addition to the packages used for actually running an application, packages might be needed for developing the software, such as:

• friendsofphp/php-cs-fixer (to detect and fix coding style issues)
• squizlabs/php_codesniffer (to detect and fix coding style issues)
• phpunit/phpunit (to drive the development using tests)
• etc.

Deployment

Now, in development and testing environments, you would typically run

$ composer install

to install both production and development dependencies.

However, in staging and production environments, you only want to install dependencies which are required for running the application, and as part of the deployment process, you would typically run

$ composer install --no-dev

to install only production dependencies.

Semantics

In other words, the sections

• require
• require-dev

indicate to composer which packages should be installed when you run

$ composer install

or

$ composer install --no-dev

That is all.

Note Development dependencies of packages your application or package depend on will never be installed

For reference, see:

• https://getcomposer.org/doc/04-schema.md#require
• https://getcomposer.org/doc/04-schema.md#require-dev

Lets try to understand in a different way.

What may happen if Abstraction is not there and What may happen if Encapsulation is not there.

If Abstraction is not there, then you can say the object is use less. You cannot identify the object nor can you access any functionality of it. Take a example of a TV, if you do not have an option to power on, change channel, increase or decrease volume etc., then what's the use of TV and how do you use it ?

If Encapsulation is not there or not being implemented properly, then you may misuse the object. There by data/components may get misused. Take the same example of TV, If there is no encapsulation done to the volume of TV, then the volume controller may be misused by making it come below or go beyond its limit (0-40/50).

/^.*?\bcat\b.*?\bmat\b.*?$/m

Using the m modifier (which ensures the beginning/end metacharacters match on line breaks rather than at the very beginning and end of the string):

• ^ matches the line beginning
• .*? matches anything on the line before...
• \b matches a word boundary the first occurrence of a word boundary (as @codaddict discussed)
• then the string cat and another word boundary; note that underscores are treated as "word" characters, so _cat_ would not match*;
• .*?: any characters before...
• boundary, mat, boundary
• .*?: any remaining characters before...
• $: the end of the line.

It's important to use \b to ensure the specified words aren't part of longer words, and it's important to use non-greedy wildcards (.*?) versus greedy (.*) because the latter would fail on strings like "There is a cat on top of the mat which is under the cat." (It would match the last occurrence of "cat" rather than the first.)

* If you want to be able to match _cat_, you can use:

/^.*?(?:\b|_)cat(?:\b|_).*?(?:\b|_)mat(?:\b|_).*?$/m

which matches either underscores or word boundaries around the specified words. (?:) indicates a non-capturing group, which can help with performance or avoid conflicted captures.

Edit: A question was raised in the comments about whether the solution would work for phrases rather than just words. The answer is, absolutely yes. The following would match "A line which includes both the first phrase and the second phrase":

/^.*?(?:\b|_)first phrase here(?:\b|_).*?(?:\b|_)second phrase here(?:\b|_).*?$/m

Edit 2: If order doesn't matter you can use:

/^.*?(?:\b|_)(first(?:\b|_).*?(?:\b|_)second|second(?:\b|_).*?(?:\b|_)first)(?:\b|_).*?$/m

And if performance is really an issue here, it's possible lookaround (if your regex engine supports it) might (but probably won't) perform better than the above, but I'll leave both the arguably more complex lookaround version and performance testing as an exercise to the questioner/reader.

Edited per @Alan Moore's comment. I didn't have a chance to test it, but I'll take your word for it.

And when you use a case :

CASE
WHEN TB1.COD IS NULL THEN
    TB1.COD || ' - ' || TB1.NAME
ELSE
    TB1.COD || ' - ' || TB1.NAME || ' - ' || TB.NM_TABELAFRETE
END AS NR_FRETE,

The sessions parameter is derived from the processes parameter and changes accordingly when you change the number of max processes. See the Oracle docs for further info.

To get only the info about the sessions:

    select current_utilization, limit_value 
    from v$resource_limit 
    where resource_name='sessions';

CURRENT_UTILIZATION LIMIT_VALUE
------------------- -----------
                110         792

Try this to show info about both:

    select resource_name, current_utilization, max_utilization, limit_value 
    from v$resource_limit 
    where resource_name in ('sessions', 'processes');

RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION LIMIT_VALUE
------------- ------------------- --------------- -----------
processes                      96             309         500
sessions                      104             323         792

If you already have checked out the code, the files are already indexed. After changing your git settings, say by running:

git config --global core.autocrlf input 

you should refresh the indexes with

git rm --cached -r . 

and re-write git index with

git reset --hard

https://help.github.com/articles/dealing-with-line-endings/#refreshing-a-repository-after-changing-line-endings

Note: this is will remove your local changes, consider stashing them before you do this.

None of the solutions worked for me. If everything else fails, get the picture to Photoshop and apply some effect. 5 minutes versus so much time on this...

From the documentation for FileSystemWatcher:

The OnCreated event is raised as soon as a file is created. If a file is being copied or transferred into a watched directory, the OnCreated event will be raised immediately, followed by one or more OnChanged events.

So, if the copy fails, (catch the exception), add it to a list of files that still need to be moved, and attempt the copy during the OnChanged event. Eventually, it should work.

Something like (incomplete; catch specific exceptions, initialize variables, etc):

public static void listener_Created(object sender, FileSystemEventArgs e)
{
    Console.WriteLine
            (
                "File Created:\n"
               + "ChangeType: " + e.ChangeType
               + "\nName: " + e.Name
               + "\nFullPath: " + e.FullPath
            );
    try {
        File.Copy(e.FullPath, @"D:\levani\FolderListenerTest\CopiedFilesFolder\" + e.Name);
    }
    catch {
        _waitingForClose.Add(e.FullPath);
    }
    Console.Read();
}

public static void listener_Changed(object sender, FileSystemEventArgs e)
{
     if (_waitingForClose.Contains(e.FullPath))
     {
          try {
              File.Copy(...);
              _waitingForClose.Remove(e.FullPath);
          }
          catch {}
     }

}

You are seeing a Git safety feature. Git refuses to update the remote branch with your branch, because your branch's head commit is not a direct descendent of the current head commit of the branch that you are pushing to.

If this were not the case, then two people pushing to the same repository at about the same time would not know that there was a new commit coming in at the same time and whoever pushed last would lose the work of the previous pusher without either of them realising this.

If you know that you are the only person pushing and you want to push an amended commit or push a commit that winds back the branch, you can 'force' Git to update the remote branch by using the -f switch.

git push -f origin master

Even this may not work as Git allows remote repositories to refuse non-fastforward pushes at the far end by using the configuration variable receive.denynonfastforwards. If this is the case the rejection reason will look like this (note the 'remote rejected' part):

 ! [remote rejected] master -> master (non-fast forward)

To get around this, you either need to change the remote repository's configuration or as a dirty hack you can delete and recreate the branch thus:

git push origin :master
git push origin master

In general the last parameter to git push uses the format <local_ref>:<remote_ref>, where local_ref is the name of the branch on the local repository and remote_ref is the name of the branch on the remote repository. This command pair uses two shorthands. :master has a null local_ref which means push a null branch to the remote side master, i.e. delete the remote branch. A branch name with no : means push the local branch with the given name to the remote branch with the same name. master in this situation is short for master:master.

In react router 4 the current route is in - this.props.location.pathname. Just get this.props and verify. If you still do not see location.pathname then you should use the decorator withRouter.

This might look something like this:

import {withRouter} from 'react-router-dom';

const SomeComponent = withRouter(props => <MyComponent {...props}/>);

class MyComponent extends React.Component {
  SomeMethod () {
    const {pathname} = this.props.location;
  }
}

*Updated

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

do:

$("button").click(function() {
    $('html,body').animate({
        scrollTop: $(".second").offset().top},
        'slow');
});

Updated Jsfiddle

Add this code to force portrait and lock it:

override func viewDidLoad() {
    super.viewDidLoad()

    // Force the device in portrait mode when the view controller gets loaded
    UIDevice.currentDevice().setValue(UIInterfaceOrientation.Portrait.rawValue, forKey: "orientation") 
}

override func shouldAutorotate() -> Bool {
    // Lock autorotate
    return false
}

override func supportedInterfaceOrientations() -> Int {

    // Only allow Portrait
    return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}

override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {

    // Only allow Portrait
    return UIInterfaceOrientation.Portrait
}

In your AppDelegate - set supportedInterfaceOrientationsForWindow to whatever orientations you want the entire application to support:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.All
} 

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

Found the simple official way after wading through the walls of text above that would make you think there is none.

Create a complete bundle with:

$ git bundle create <filename> --all

Restore it with:

$ git clone <filename> <folder>

This operation is atomic AFAIK. Check official docs for the gritty details.

Regarding "zip": git bundles are compressed and surprisingly small compared to the .git folder size.

Setting the following option:

set  disassemble-next-line on
show disassemble-next-line

Will give you results that look like this:

(gdb) stepi
0x000002ce in ResetISR () at startup_gcc.c:245
245 {
   0x000002cc <ResetISR+0>: 80 b5   push    {r7, lr}
=> 0x000002ce <ResetISR+2>: 82 b0   sub sp, #8
   0x000002d0 <ResetISR+4>: 00 af   add r7, sp, #0
(gdb) stepi
0x000002d0  245 {

=> 0x000002d0 <ResetISR+4>: 00 af   add r7, sp, #0

You can simply use DataColumnCollection.IndexOf

So that you can get the index of the required column by name then use it with your row:

row[dt.Columns.IndexOf("ColumnName")] = columnValue;

Actually this is kind of strange, with the string conversions - which the membership provider does to put them into config files. Hashes and salts are binary blobs, you don't need to convert them to strings unless you want to put them into text files.

In my book, Beginning ASP.NET Security, (oh finally, an excuse to pimp the book) I do the following

static byte[] GenerateSaltedHash(byte[] plainText, byte[] salt)
{
  HashAlgorithm algorithm = new SHA256Managed();

  byte[] plainTextWithSaltBytes = 
    new byte[plainText.Length + salt.Length];

  for (int i = 0; i < plainText.Length; i++)
  {
    plainTextWithSaltBytes[i] = plainText[i];
  }
  for (int i = 0; i < salt.Length; i++)
  {
    plainTextWithSaltBytes[plainText.Length + i] = salt[i];
  }

  return algorithm.ComputeHash(plainTextWithSaltBytes);            
}

The salt generation is as the example in the question. You can convert text to byte arrays using Encoding.UTF8.GetBytes(string). If you must convert a hash to its string representation you can use Convert.ToBase64String and Convert.FromBase64String to convert it back.

You should note that you cannot use the equality operator on byte arrays, it checks references and so you should simply loop through both arrays checking each byte thus

public static bool CompareByteArrays(byte[] array1, byte[] array2)
{
  if (array1.Length != array2.Length)
  {
    return false;
  }

  for (int i = 0; i < array1.Length; i++)
  {
    if (array1[i] != array2[i])
    {
      return false;
    }
  }

  return true;
}

Always use a new salt per password. Salts do not have to be kept secret and can be stored alongside the hash itself.

There are two options:

Using Imports

This is the suggested option. It ensures your fonts go through the build pipeline, get hashes during compilation so that browser caching works correctly, and that you get compilation errors if the files are missing.

As described in “Adding Images, Fonts, and Files”, you need to have a CSS file imported from JS. For example, by default src/index.js imports src/index.css:

import './index.css';

A CSS file like this goes through the build pipeline, and can reference fonts and images. For example, if you put a font in src/fonts/MyFont.woff, your index.css might include this:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(./fonts/MyFont.woff) format('woff');
}

Notice how we’re using a relative path starting with ./. This is a special notation that helps the build pipeline (powered by Webpack) discover this file.

Normally this should be enough.

Using public Folder

If for some reason you prefer not to use the build pipeline, and instead do it the “classic way”, you can use the public folder and put your fonts there.

The downside of this approach is that the files don’t get hashes when you compile for production so you’ll have to update their names every time you change them, or browsers will cache the old versions.

If you want to do it this way, put the fonts somewhere into the public folder, for example, into public/fonts/MyFont.woff. If you follow this approach, you should put CSS files into public folder as well and not import them from JS because mixing these approaches is going to be very confusing. So, if you still want to do it, you’d have a file like public/index.css. You would have to manually add <link> to this stylesheet from public/index.html:

<link rel="stylesheet" href="%PUBLIC_URL%/index.css">

And inside of it, you would use the regular CSS notation:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(fonts/MyFont.woff) format('woff');
}

Notice how I’m using fonts/MyFont.woff as the path. This is because index.css is in the public folder so it will be served from the public path (usually it’s the server root, but if you deploy to GitHub Pages and set your homepage field to http://myuser.github.io/myproject, it will be served from /myproject). However fonts are also in the public folder, so they will be served from fonts relatively (either http://mywebsite.com/fonts or http://myuser.github.io/myproject/fonts). Therefore we use the relative path.

Note that since we’re avoiding the build pipeline in this example, it doesn’t verify that the file actually exists. This is why I don’t recommend this approach. Another problem is that our index.css file doesn’t get minified and doesn’t get a hash. So it’s going to be slower for the end users, and you risk the browsers caching old versions of the file.

 Which Way to Use?

Go with the first method (“Using Imports”). I only described the second one since that’s what you attempted to do (judging by your comment), but it has many problems and should only be the last resort when you’re working around some issue.

textarea {
border: 0;
overflow: auto; }

less CSS ^ you can't align the text to the bottom unfortunately.

I think you mean to update it back to the OLD password, when the NEW one is not supplied.

DROP TRIGGER IF EXISTS upd_user;

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '') THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

However, this means a user can never blank out a password.

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

in python sorted works like you want with integers:

>>> sorted([10,3,2])
[2, 3, 10]

it looks like you have a problem because you are using strings:

>>> sorted(['10','3','2'])
['10', '2', '3']

(because string ordering starts with the first character, and "1" comes before "2", no matter what characters follow) which can be fixed with key=int

>>> sorted(['10','3','2'], key=int)
['2', '3', '10']

which converts the values to integers during the sort (it is called as a function - int('10') returns the integer 10)

and as suggested in the comments, you can also sort the list itself, rather than generating a new one:

>>> l = ['10','3','2']
>>> l.sort(key=int)
>>> l
['2', '3', '10']

but i would look into why you have strings at all. you should be able to save and retrieve integers. it looks like you are saving a string when you should be saving an int? (sqlite is unusual amongst databases, in that it kind-of stores data in the same type as it is given, even if the table column type is different).

and once you start saving integers, you can also get the list back sorted from sqlite by adding order by ... to the sql command:

select temperature from temperatures order by temperature;

Open the ~/.bashrc file using vi/vim $ vi ~/.bashrc

Enter the following by pressing i to insert:

code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}

Save the file using :wq

Reflect the settings in ~/.bashrc using the following command:

source ~/.bashrc

There is a difference between . and text(), but this difference might not surface because of your input document.

If your input document looked like (the simplest document one can imagine given your XPath expressions)

Example 1

<html>
  <a>Ask Question</a>
</html>

Then //a[text()="Ask Question"] and //a[.="Ask Question"] indeed return exactly the same result. But consider a different input document that looks like

Example 2

<html>
  <a>Ask Question<other/>
  </a>
</html>

where the a element also has a child element other that follows immediately after "Ask Question". Given this second input document, //a[text()="Ask Question"] still returns the a element, while //a[.="Ask Question"] does not return anything!

This is because the meaning of the two predicates (everything between [ and ]) is different. [text()="Ask Question"] actually means: return true if any of the text nodes of an element contains exactly the text "Ask Question". On the other hand, [.="Ask Question"] means: return true if the string value of an element is identical to "Ask Question".

In the XPath model, text inside XML elements can be partitioned into a number of text nodes if other elements interfere with the text, as in Example 2 above. There, the other element is between "Ask Question" and a newline character that also counts as text content.

To make an even clearer example, consider as an input document:

Example 3

<a>Ask Question<other/>more text</a>

Here, the a element actually contains two text nodes, "Ask Question" and "more text", since both are direct children of a. You can test this by running //a/text() on this document, which will return (individual results separated by ----):

Ask Question
-----------------------
more text

So, in such a scenario, text() returns a set of individual nodes, while . in a predicate evaluates to the string concatenation of all text nodes. Again, you can test this claim with the path expression //a[.='Ask Questionmore text'] which will successfully return the a element.

Finally, keep in mind that some XPath functions can only take one single string as an input. As LarsH has pointed out in the comments, if such an XPath function (e.g. contains()) is given a sequence of nodes, it will only process the first node and silently ignore the rest.

Try this: currentLoad = ConvertToLongInteger(oXLSheet2.Cells(4, 6).Value) with this function:

Function ConvertToLongInteger(ByVal stValue As String) As Long
 On Error GoTo ConversionFailureHandler
 ConvertToLongInteger = CLng(stValue)  'TRY to convert to an Integer value
 Exit Function           'If we reach this point, then we succeeded so exit

ConversionFailureHandler:
 'IF we've reached this point, then we did not succeed in conversion
 'If the error is type-mismatch, clear the error and return numeric 0 from the function
 'Otherwise, disable the error handler, and re-run the code to allow the system to 
 'display the error
 If Err.Number = 13 Then 'error # 13 is Type mismatch
      Err.Clear
      ConvertToLongInteger = 0
      Exit Function
 Else
      On Error GoTo 0
      Resume
 End If
End Function

I chose Long (Integer) instead of simply Integer because the min/max size of an Integer in VBA is crummy (min: -32768, max:+32767). It's common to have an integer outside of that range in spreadsheet operations.

The above code can be modified to handle conversion from string to-Integers, to-Currency (using CCur() ), to-Decimal (using CDec() ), to-Double (using CDbl() ), etc. Just replace the conversion function itself (CLng). Change the function return type, and rename all occurrences of the function variable to make everything consistent.

This is a mix of the two previous answers:

  PreparedStatement ps = c.prepareStatement("INSERT INTO employees VALUES (?, ?)");

  ps.setString(1, "John");
  ps.setString(2,"Doe");
  ps.addBatch();

  ps.clearParameters();
  ps.setString(1, "Dave");
  ps.setString(2,"Smith");
  ps.addBatch();

  ps.clearParameters();
  int[] results = ps.executeBatch();

C#: try this

• yyyy(yy/yyy) - years
• MM - months(like '03'), MMMM - months(like 'March')
• dd - days(like 09), ddd/dddd - days(Sun/Sunday)
• hh - hour 12(AM/PM), HH - hour 24
• mm - minute
• ss - second

Use some delimeter,like this:

1. MessageBox.Show(DateValue.ToString("yyyy-MM-dd")); example result: "2014-09-30"
2. empty format string: MessageBox.Show(DateValue.ToString()); example result: "30.09.2014 0:00:00"

Use the Linux Command Line

Use the command line, as described in this related question: How do I check if my SSL Certificate is SHA1 or SHA2 on the commandline.

Command

Here's the command. Replace www.yoursite.com:443 to fit your needs. Default SSL port is 443:

openssl s_client -connect www.yoursite.com:443 < /dev/null 2>/dev/null \
    | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm"

Results

This should return something like this for the sha1:

Signature Algorithm: sha1WithRSAEncryption

or this for the newer version:

Signature Algorithm: sha256WithRSAEncryption

References

The article Why Google is Hurrying the Web to Kill SHA-1 describes exactly what you would expect and has a pretty graphic, too.

If you want to call JavaScript function in C#, this will help you:

public string functionname(arg)
{
    if (condition)
    {
        Page page = HttpContext.Current.CurrentHandler as Page;
        page.ClientScript.RegisterStartupScript(
            typeof(Page),
            "Test",
            "<script type='text/javascript'>functionname1(" + arg1 + ",'" + arg2 + "');</script>");
    }
}

Putting the other answers all together, here's a command line that will work:

env vblank_mode=0 __GL_SYNC_TO_VBLANK=0 glxgears

This has the advantages of working for both Mesa and NVidia drivers, and not requiring any changes to configuration files.

I think you need a floor function :

math.floor(x)

here's a sample code for python,

from boto3 import client as boto3_client
from datetime import datetime
import json

lambda_client = boto3_client('lambda')

def lambda_handler(event, context):
    msg = {"key":"new_invocation", "at": datetime.now()}
    invoke_response = lambda_client.invoke(FunctionName="another_lambda_",
                                           InvocationType='Event',
                                           Payload=json.dumps(msg))
    print(invoke_response)

Btw, you would need to add a policy like this to your lambda role as well

   {
        "Sid": "Stmt1234567890",
        "Effect": "Allow",
        "Action": [
            "lambda:InvokeFunction"
        ],
        "Resource": "*"
    }

You can add property to your model as follows:

    public string DetailsClass { get { return Details.Count > 0 ? "show" : "hide" } }

and then your view will be simpler and will contain no logic at all:

    <div class="details @Model.DetailsClass"/>

This will work even with many classes and will not render class if it is null:

    <div class="@Model.Class1 @Model.Class2"/>

with 2 not null properties will render:

    <div class="class1 class2"/>

if class1 is null

    <div class=" class2"/>

Javascript to be placed in header:

function resizeIframe(obj) {
        obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
      }

Here goes iframe html code:

<iframe class="spec_iframe" seamless="seamless" frameborder="0" scrolling="no" id="iframe" onload="javascript:resizeIframe(this);" src="somepage.php" style="height: 1726px;"></iframe>

Css stylesheet

>

.spec_iframe {
        width: 100%;
        overflow: hidden;
    }

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

Rather than going for a direct command, please move required files to temp dir outside current dir. Then delete all files using rm * or rm -r *.

Then move required files to current dir.

You state in the comments that the returned JSON is this:

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

You're telling Gson that you have an array of Post objects:

List<Post> postsList = Arrays.asList(gson.fromJson(reader,
                    Post[].class));

You don't. The JSON represents exactly one Post object, and Gson is telling you that.

Change your code to be:

Post post = gson.fromJson(reader, Post.class);

First, it violates two principles of Zen of Python:

• Explicit is better than implicit
• Errors should never pass silently

What it means, is that you intentionally make your error pass silently. Moreover, you don't event know, which error exactly occurred, because except: pass will catch any exception.

Second, if we try to abstract away from the Zen of Python, and speak in term of just sanity, you should know, that using except:pass leaves you with no knowledge and control in your system. The rule of thumb is to raise an exception, if error happens, and take appropriate actions. If you don't know in advance, what actions these should be, at least log the error somewhere (and better re-raise the exception):

try:
    something
except:
    logger.exception('Something happened')

But, usually, if you try to catch any exception, you are probably doing something wrong!

WinForms

For multi-monitor setups you will also need account for the X and Y position:

Rectangle activeScreenDimensions = Screen.FromControl(this).Bounds;
this.Size = new Size(activeScreenDimensions.Width + activeScreenDimensions.X, activeScreenDimensions.Height + activeScreenDimensions.Y);

By default, all output goes to stdout, which is the HTTP response or the console, depending on whether your script is run by Apache or manually on the command line. But you can use error_log for logging and various I/O streams can be written to with fwrite.

Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");

try this.

table 
{
    background-color: #aaa;
}

tbody 
{
    background-color: #ddd;
    height: 100px;
    overflow-y: scroll;
    position: absolute;
}

td 
{
    padding: 3px 10px;
    color: green;
    width: 100px;
}

INDEX=0
for i in $list; do 
    echo ${INDEX}_$i
    let INDEX=${INDEX}+1
done

You have a few typos in your select. It should be: input:not([disabled]):not([type="submit"]):focus

See this jsFiddle for a proof of concept. On a sidenote, if I removed the "background-color" property, then the box shadow no longer works. Not sure why.

I was able to fully automate it with the following command:

echo pass | ssh -tt user@server "sudo script"

Advantages:

• no password prompt
• won't show password in remote machine bash history

Regarding security: as Kurt said, running this command will show your password on your local bash history, and it's better to save the password in a different file or save the all command in a .sh file and execute it. NOTE: The file need to have the correct permissions so that only the allowed users can access it.

The easiest way I've found is delete Android Studio from the applications folder, then download & install it again.

You could use absolute positioning to pin the footer to the base of the parent div. I have also added 10px padding-bottom to the wrap (match the height of the footer). The absolute positioning is relative to the parent div rather than outside of the flow since you have already given it the position relative attribute.

body{ height:20000px }
#wrapper {padding:10%;}
#wrap{ 
    float: left;
    padding-bottom: 10px;
    position: relative;
    width: 40%; 
    background:#ccc; 
}
#fixed{ 
    position:absolute;
    width:100%;
    left: 0;
    bottom: 0;
    padding:0px;
    height:10px;
    background-color:#333;

}

Use ngModelChange by breaking up the [(x)] syntax into its two pieces, i.e., property databinding and event binding:

<input type="text" [ngModel]="mymodel" (ngModelChange)="valuechange($event)" />
{{mymodel}}

valuechange(newValue) {
  mymodel = newValue;
  console.log(newValue)
}

It works for the backspace key too.

Did you set the CSS:

html, body
{
    height: 100%;
}

You need this to be able to make the div take up all the space. :)

to deal with Null Comparisons use Object.Equals() instead of ==

I am just wondering why to use some libraries for JWT token decoding and verification at all.

Encoded JWT token can be created using following pseudocode

var headers = base64URLencode(myHeaders);
var claims = base64URLencode(myClaims);
var payload = header + "." + claims;

var signature = base64URLencode(HMACSHA256(payload, secret));

var encodedJWT = payload + "." + signature;

It is very easy to do without any specific library. Using following code:

using System;
using System.Text;
using System.Security.Cryptography;

public class Program
{   
    // More info: https://stormpath.com/blog/jwt-the-right-way/
    public static void Main()
    {           
        var header = "{\"typ\":\"JWT\",\"alg\":\"HS256\"}";
        var claims = "{\"sub\":\"1047986\",\"email\":\"[email protected]\",\"given_name\":\"John\",\"family_name\":\"Doe\",\"primarysid\":\"b521a2af99bfdc65e04010ac1d046ff5\",\"iss\":\"http://example.com\",\"aud\":\"myapp\",\"exp\":1460555281,\"nbf\":1457963281}";

        var b64header = Convert.ToBase64String(Encoding.UTF8.GetBytes(header))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");
        var b64claims = Convert.ToBase64String(Encoding.UTF8.GetBytes(claims))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        var payload = b64header + "." + b64claims;
        Console.WriteLine("JWT without sig:    " + payload);

        byte[] key = Convert.FromBase64String("mPorwQB8kMDNQeeYO35KOrMMFn6rFVmbIohBphJPnp4=");
        byte[] message = Encoding.UTF8.GetBytes(payload);

        string sig = Convert.ToBase64String(HashHMAC(key, message))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        Console.WriteLine("JWT with signature: " + payload + "." + sig);        
    }

    private static byte[] HashHMAC(byte[] key, byte[] message)
    {
        var hash = new HMACSHA256(key);
        return hash.ComputeHash(message);
    }
}

The token decoding is reversed version of the code above.To verify the signature you will need to the same and compare signature part with calculated signature.

UPDATE: For those how are struggling how to do base64 urlsafe encoding/decoding please see another SO question, and also wiki and RFCs

To convert any object or object list into JSON, we have to use the function JsonConvert.SerializeObject.

The below code demonstrates the use of JSON in an ASP.NET environment:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Newtonsoft.Json;
using System.Collections.Generic;

namespace JSONFromCS
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e1)
        {
            List<Employee> eList = new List<Employee>();
            Employee e = new Employee();
            e.Name = "Minal";
            e.Age = 24;

            eList.Add(e);

            e = new Employee();
            e.Name = "Santosh";
            e.Age = 24;

            eList.Add(e);

            string ans = JsonConvert.SerializeObject(eList, Formatting.Indented);

            string script = "var employeeList = {\"Employee\": " + ans+"};";
            script += "for(i = 0;i<employeeList.Employee.length;i++)";
            script += "{";
            script += "alert ('Name : ='+employeeList.Employee[i].Name+' 
            Age : = '+employeeList.Employee[i].Age);";
            script += "}";

            ClientScriptManager cs = Page.ClientScript;
            cs.RegisterStartupScript(Page.GetType(), "JSON", script, true);
        }
    }
    public class Employee
    {
        public string Name;
        public int Age;
    }
}  

After running this program, you will get two alerts

In the above example, we have created a list of Employee object and passed it to function "JsonConvert.SerializeObject". This function (JSON library) will convert the object list into JSON format. The actual format of JSON can be viewed in the below code snippet:

{ "Maths" : [ {"Name"     : "Minal",        // First element
                             "Marks"     : 84,
                             "age"       : 23 },
                             {
                             "Name"      : "Santosh",    // Second element
                             "Marks"     : 91,
                             "age"       : 24 }

Syntax:

• {} - acts as 'containers'

• [] - holds arrays

• : - Names and values are separated by a colon

• , - Array elements are separated by commas

This code is meant for intermediate programmers, who want to use C# 2.0 to create JSON and use in ASPX pages.

You can create JSON from JavaScript end, but what would you do to convert the list of object into equivalent JSON string from C#. That's why I have written this article.

In C# 3.5, there is an inbuilt class used to create JSON named JavaScriptSerializer.

The following code demonstrates how to use that class to convert into JSON in C#3.5.

JavaScriptSerializer serializer = new JavaScriptSerializer()
return serializer.Serialize(YOURLIST);   

So, try to create a List of arrays with Questions and then serialize this list into JSON

This will do it if you only want the first "B" value, you can sub a cell address for "B" if you want to make it more generic.

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(B2:B6)="B",0)),1)

To use this based on two columns, just concatenate inside the match:

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(A2:A6&B2:B6)=("3"&"B"),0)),1)

Here's a one-liner that doesn't require any external scripts or utilities and doesn't require you to start the process via another program like Valgrind or time, so you can use it for any process that's already running:

grep VmPeak /proc/$PID/status

(replace $PID with the PID of the process you're interested in)

Rational and Together/J are best-of-breed products, but expensive.

In my experience, I've enjoyed Eclipse Omondo and Sparx Enterprise Architect. Omondo integrates nicely with Eclipse for code generation, and has a very intuitive feel. However, it is strongly tied to Java. Sparx is a good tool for the price point, but lacks the full range of UML 2.0 diagrams.

Do NOT bother with Poseidon. It is buggy, bloated, and unusuable for all intents and purposes.

Best way to execute block of code after Spring Boot application started is using PostConstruct annotation.Or also you can use command line runner for the same.

1. Using PostConstruct annotation

@Configuration
public class InitialDataConfiguration {

    @PostConstruct
    public void postConstruct() {
        System.out.println("Started after Spring boot application !");
    }

}

2. Using command line runner bean

@Configuration
public class InitialDataConfiguration {

    @Bean
    CommandLineRunner runner() {
        return args -> {
            System.out.println("CommandLineRunner running in the UnsplashApplication class...");
        };
    }
}

Well, the window is the first thing that gets loaded into the browser. This window object has the majority of the properties like length, innerWidth, innerHeight, name, if it has been closed, its parents, and more.

What about the document object then? The document object is your html, aspx, php, or other document that will be loaded into the browser. The document actually gets loaded inside the window object and has properties available to it like title, URL, cookie, etc. What does this really mean? That means if you want to access a property for the window it is window.property, if it is document it is window.document.property which is also available in short as document.property.

That seems simple enough. But what happens once an IFRAME is introduced?

1. Create a new folder in Drive and share it as "Public on the web."
2. Upload your HTML, JS & CSS files to this folder.
3. Open the HTML file & you will see "Preview" button in the toolbar.
4. Share the URL that looks like www.googledrive.com/host/... from the preview window and anyone can view your web page.

When I had similar issue it's happened because my lib was build using clang++, and it's linked to libstdc++.so by default on my system. While app binary was build using clang and linked with -lc++ option.

Easiest way to check dependencies is to perform ldd libName.so

To fix it you should use the same library on in app and library.

• Easiest way. Build library using clang++ and compile app using clang++. Without extra linking options on both steps. Default stdlib will be used.

• Build library with -stdlib=c++ and compile app with -lc++. In this case both library and app will use libc++.so.

• Build library without extra options and link binary to -lstdc++. In this case both library and app will use libstdc++.so.

You can use like this;

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String d = "2000-01-30";
Date date= new Date(sdf.parse(d).getTime());
date.setMonth(date.getMonth() + 1);

When I received this error, I had a "helper" class that I did not declare as public that caused this issue inside of the class that used the "helper" class. Making the "helper" class public solved this error, as in:

public ServiceClass { public ServiceClass(HelperClass _helper) { } }

public class HelperClass {} // Note the public HelperClass that solved my issue.

This may help someone else who encounters this.

Personally I stumbled on a similar error message in this scenario:

I created a folder that has been empty, so naturally as long as it is empty, typing git add * will not take this empty folder in consideration. So when I tried to run git rm -r * or simply git rm my_empty_folder/ -r, I got that error message.

The solution is to simply remove it without git: rm -r my_empty_folder/ or create a data file within this folder and then add it (git add my_no_long_empty_folder)

Left Click on chart. «PivotTable Field List» will appear on right. On the right down quarter of PivotTable Field List (S Values), you see the names of the legends. Left Click on the legend name. Left Click on the «Value field settings». At the top there is «Source Name». You can’t change it. Below there is «Custom Name». Change the Custom Name as you wish. Now the legend name on the chart has the new name you gave.

To update entries other than appsettings, simply use XmlDocument.

public static void UpdateAppConfig(string tagName, string attributeName, string value)
{
    var doc = new XmlDocument();
    doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
    var tags = doc.GetElementsByTagName(tagName);
    foreach (XmlNode item in tags)
    {
        var attribute = item.Attributes[attributeName];
        if (!ReferenceEquals(null, attribute))
            attribute.Value = value;
    }
    doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
}

This is how you call it:

Utility.UpdateAppConfig("endpoint", "address", "http://localhost:19092/NotificationSvc/Notification.svc");

Utility.UpdateAppConfig("network", "host", "abc.com.au");

This method can be improved to cater for appSettings values as well.

The underlying ideas are straight:

• Use . with structure variable. (Cases 2 and 4)
• Use -> with pointer to structure. (Cases 1 and 3)
• If you reach structure variable or pointer to structure variable by following pointer, then wrap the pointer inside bracket: (*ptr). and (*ptr)-> vs *ptr. and *ptr-> (All cases except case 1)
• If you are reaching by following pointers, ensure you have correctly reached pointer to struct or struct whichever is desired. (Case 5, especially 5.5)

The default parser can parse your input. So you don't need a custom formatter and

String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);

works as expected.

Just had the same error message, but when I was running a package.json with:

"scripts": {
    "build": "tsc -p ./src",
}

tsc is the command to run the TypeScript compiler.

I never had any issues with this project because I had TypeScript installed as a global module. As this project didn't include TypeScript as a dev dependency (and expected it to be installed as global), I had the error when testing in another machine (without TypeScript) and running npm install didn't fix the problem. So I had to include TypeScript as a dev dependency (npm install typescript --save-dev) to solve the problem.

It can be very pragmatic to configure specific infrastructure concerns as singletons or global variables. My favourite example of this is Dependency Injection frameworks that make use of singletons to act as a connection point to the framework.

In this case you are taking a dependency on the infrastructure to simplify using the library and avoid unneeded complexity.

When dealing with dates in SQL Server, the ISO-8601 format is probably the best way to go, since it just works regardless of your language and culture settings.

In order to INSERT data into a SQL Server table, you don't need any conversion codes or anything at all - just specify your dates as literal strings

INSERT INTO MyTable(DateColumn) VALUES('20090430 12:34:56.790')

and you're done.

If you need to convert a date column to ISO-8601 format on SELECT, you can use conversion code 126 or 127 (with timezone information) to achieve the ISO format.

SELECT CONVERT(VARCHAR(33), DateColumn, 126) FROM MyTable

should give you:

2009-04-30T12:34:56.790

      List<T> list
 )

The getActionCommand() method returns an String associated with that Component set through the setActionCommand() , whereas the getSource() method returns an Object of the Object class specifying the source of the event.

You must fill the "Button" attribute of the "CompoundButton" class with a XML drawable path (my_checkbox). In the XML drawable, you must have :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_checked="false" android:drawable="@drawable/checkbox_not_checked" />
     <item android:state_checked="true" android:drawable="@drawable/checkbox_checked" />
     <item android:drawable="@drawable/checkbox_not_checked" /> <!-- default -->
</selector>

Don't forget to replace my_checkbox by your filename of the checkbox drawable , checkbox_not_checked by your PNG drawable which is your checkbox when it's not checked and checkbox_checked with your image when it's checked.

For the size, directly update the layout parameters.

Slightly different option usually works for me:

1. "mvn eclipse:eclipse" for this project in the command line.
2. "Refresh/F5" this project in eclipse.

That's all, no need to re-import but need to have the terminal window handy.

In C++11:

static const int a[] = {10, 20, 30};
vector<int> vec (begin(a), end(a));

What you need is strstr()(or stristr(), like LucaB pointed out). Use it like this:

if(strstr($text, "world")) {/* do stuff */}

Another answer relies on the third-to-last character being a space. This will work with (almost) any character in that position and does it "WITHOUT using sed, or perl, etc.":

while read -r line
do
    echo ${line:0:${#line}-3}
done

If your lines are fixed length change the echo to:

echo ${line:0:9}

or

printf "%.10s\n" "$line"

but each of these is definitely much slower than sed.

Keep in mind that there are processes on the database which may not currently support a session.

If you're interested in all processes you'll want to look to v$process (or gv$process on RAC)

They can be in separate containers, and indeed, if the application was also intended to run in a larger environment, they probably would be.

A multi-container system would require some more orchestration to be able to bring up all the required dependencies, though in Docker v0.6.5+, there is a new facility to help with that built into Docker itself - Linking. With a multi-machine solution, its still something that has to be arranged from outside the Docker environment however.

With two different containers, the two parts still communicate over TCP/IP, but unless the ports have been locked down specifically (not recommended, as you'd be unable to run more than one copy), you would have to pass the new port that the database has been exposed as to the application, so that it could communicate with Mongo. This is again, something that Linking can help with.

For a simpler, small installation, where all the dependencies are going in the same container, having both the database and Python runtime started by the program that is initially called as the ENTRYPOINT is also possible. This can be as simple as a shell script, or some other process controller - Supervisord is quite popular, and a number of examples exist in the public Dockerfiles.

Use git log to find the revision you want to rollback to, and take note of the commit hash. After that, you have 2 options:

1. If you plan to commit anything after that revision, I recommend you to checkout to a new branch: git checkout -b <new_branch_name> <hash>

2. If you don't plan to commit anything after that revision, you can simply checkout without a branch: git checkout <hash> - NOTE: This will put your repository in a 'detached HEAD' state, which means its currently not attached to any branch - then you'll have some extra work to merge new commits to an actual branch.

Example:

$ git log
commit 89915b4cc0810a9c9e67b3706a2850c58120cf75
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:15:01 2010 -0300

    Added a custom extension.

commit 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:13:48 2010 -0300

    Missing constness.

$ git checkout 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Note: moving to '4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7'
which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 4553c14... Missing constness.

That way you don't lose any informations, thus you can move to a newer revision when it becomes stable.

The one that got me was similar to the other poster's "tbl" prefix for SQL table names.

In this case, the prefix for all stored procedures was to be "sp_" despite the fact that "sp_" is a prefix used by Microsoft for system-level stored procedures in SQL Server. Well, they had their standards from an old, non-MS database and weren't about to change just because their standard might cause a stored procedure to collide with a system stored procedure and produce unpredictable results. No, that just wouldn't be proper.

The first code is an example of Javascript code, which is similar, however not JSON. JSON would not have 1) comments and 2) the var keyword

You don't have any comments in your JSON, but you should remove the var and start like this:

orders: {

The [{}] notation means "object in an array" and is not what you need everywhere. It is not an error, but it's too complicated for some purposes. AssociatedDrug should work well as an object:

"associatedDrug": {
                "name":"asprin",
                "dose":"",
                "strength":"500 mg"
          }

Also, the empty object labs should be filled with something.

Other than that, your code is okay. You can either paste it into javascript, or use the JSON.parse() method, or any other parsing method (please don't use eval)

Update 2 answered:

obj.problems[0].Diabetes[0].medications[0].medicationsClasses[0].className[0].associatedDrug[0].name

returns 'aspirin'. It is however better suited for foreaches everywhere

Static members need to be initialized in a .cpp translation unit at file scope or in the appropriate namespace:

const string foo::s( "my foo");

For me, the issue was that I had a broken symbolic link on the file I was trying to mount into the container

Update

Based on Manipulating the browser history, passing the empty string as second parameter of pushState method (aka title) should be safe against future changes to the method, so it's better to use pushState like this:

history.pushState(null, '', '/en/step2');    

You can read more about that in mentioned article

Original Answer

Use history.pushState like this:

history.pushState(null, null, '/en/step2');

• More info (MDN article): Manipulating the browser history
• Can I use
• Maybe you should take a look @ Does Internet Explorer support pushState and replaceState?

Update 2 to answer Idan Dagan's comment:

Why not using history.replaceState()?

From MDN

history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one

That means if you use replaceState, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState doesn't add new entry to history) and it's not recommended and provide bad UX.

Update 3 to add window.onpopstate

So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState, you can detect the back/forward button navigation by using window.onpopstate like this:

window.onpopstate = function(e) {
    // ... 
};

As the first argument of pushState is an object, if you passed an object instead of null, you can access that object in onpopstate which is very handy, here is how:

window.onpopstate = function(e) {
    if(e.state) {
        console.log(e.state);
    }
};

Update 4 to add Reading the current state:

When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate event using the history.state property like this:

console.log(history.state);

Bonus: Use following to check history.pushState support:

if (history.pushState) {
  // \o/
}

Yes numpy has a size function, and shape and size are not quite the same.

Input

import numpy as np
data = [[1, 2, 3, 4], [5, 6, 7, 8]]
arrData = np.array(data)

print(data)
print(arrData.size)
print(arrData.shape)

Output

[[1, 2, 3, 4], [5, 6, 7, 8]]

8 # size

(2, 4) # shape

I also had to register the closing function inside the form's "InitializeComponent()" method:

private void InitializeComponent() {
// ...
this.FormClosing += FrmMain_FormClosing;
// ...
}

My "FormClosing" function looks similar to the given answer (https://stackoverflow.com/a/2683846/3323790):

private void FrmMain_FormClosing(object sender, FormClosingEventArgs e) {
    if (e.CloseReason == CloseReason.UserClosing){
        MessageBox.Show("Closed by User", "UserClosing");
    }

    if (e.CloseReason == CloseReason.WindowsShutDown){
        MessageBox.Show("Closed by Windows shutdown", "WindowsShutDown");
    }
}

One more thing to mention: There is also a "FormClosed" function which occurs after "FormClosing". To use this function, register it as shown below:

this.FormClosed += MainPage_FormClosed;

private void MainPage_FormClosing(object sender, FormClosingEventArgs e)
{
// your code after the form is closed
}

Another way to extend (specifically meaning, add new methods, not change existing ones) classes, even built-in ones, is to use a preprocessor that adds the ability to extend out of/above the scope of Python itself, converting the extension to normal Python syntax before Python actually gets to see it.

I've done this to extend Python 2's str() class, for instance. str() is a particularly interesting target because of the implicit linkage to quoted data such as 'this' and 'that'.

Here's some extending code, where the only added non-Python syntax is the extend:testDottedQuad bit:

extend:testDottedQuad
def testDottedQuad(strObject):
    if not isinstance(strObject, basestring): return False
    listStrings = strObject.split('.')
    if len(listStrings) != 4: return False
    for strNum in listStrings:
        try:    val = int(strNum)
        except: return False
        if val < 0: return False
        if val > 255: return False
    return True

After which I can write in the code fed to the preprocessor:

if '192.168.1.100'.testDottedQuad():
    doSomething()

dq = '216.126.621.5'
if not dq.testDottedQuad():
    throwWarning();

dqt = ''.join(['127','.','0','.','0','.','1']).testDottedQuad()
if dqt:
    print 'well, that was fun'

The preprocessor eats that, spits out normal Python without monkeypatching, and Python does what I intended it to do.

Just as a c preprocessor adds functionality to c, so too can a Python preprocessor add functionality to Python.

My preprocessor implementation is too large for a stack overflow answer, but for those who might be interested, it is here on GitHub.

On Linux/Unix (note: Mac OS is a Unix) use top and press M (Shift+M) to sort processes by memory usage.

On Windows use the Task Manager.

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

also see:

CustomErrors mode="Off"

By specifying the positions we can achieve this,

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  position:relative;
  overflow:auto;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  
  float:left;
}
.div3 {
  width:150px;
  height:100%;
  position:absolute;
  right:0px;
  background-color: #FFFFE0;  
  float:right;
}

but it is not possible to achieve this using float.

After many struggles and to achive a general, flexible and more readable solution, in my case I ended up saving the ORs results into ENV variables and doing the ANDs of those variables.

# RESULT_ONE = A OR B
RewriteRule ^ - [E=RESULT_ONE:False]
RewriteCond ...A... [OR]
RewriteCond ...B...
RewriteRule ^ - [E=RESULT_ONE:True]

# RESULT_TWO = C OR D
RewriteRule ^ - [E=RESULT_TWO:False]
RewriteCond ...C... [OR]
RewriteCond ...D...
RewriteRule ^ - [E=RESULT_TWO:True]

# if ( RESULT_ONE AND RESULT_TWO ) then ( RewriteRule ...something... )
RewriteCond %{ENV:RESULT_ONE} =True
RewriteCond %{ENV:RESULT_TWO} =True
RewriteRule ...something...

Requirements:

• Apache mod_env enabled

Laravel 4.2 and beyond, may use try relationship querying:-

Products::whereHas('product_category', function($query) {
$query->whereIn('category_id', ['223', '15']);
});

public function product_category() {
return $this->hasMany('product_category', 'product_id');
}

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

JSONP does not work with basic authentication so the jQuery beforeSend callback won't work with JSONP/Script.

I managed to work around this limitation by adding the user and password to the request (e.g. user:[email protected]). This works with pretty much any browser except Internet Explorer where authentication through URLs is not supported (the call will simply not be executed).

See http://support.microsoft.com/kb/834489.

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

• if you unable to find assembly reference from when (Right click on reference ->add required assembly)

try this Package manager console
Install-Package System.Net.Http.Formatting.Extension -Version 5.2.3 and then add by using add reference .

Another thought for making that easier when using an automated build:

When you create a jar of one of your projects, also create a source files jar:
project.jar
project-src.jar

Instead of going into the build path options dialog to add a source reference to each jar, try the following: add one source reference through the dialog. Edit your .classpath and using the first jar entry as a template, add the source jar files to each of your other jars.

This way you can use Eclipse's navigation aids to their fullest while still using something more standalone to build your projects.

select name, max(value)
from out_pumptable
group by name

I made my own way based on Caitlin Morris's answer for fetching all folowers and followings on Instagram. Just copy this code, paste in browser console and wait for a few seconds.

You need to use browser console from instagram.com tab to make it works.

let username = 'USERNAME'
let followers = [], followings = []
try {
  let res = await fetch(`https://www.instagram.com/${username}/?__a=1`)

  res = await res.json()
  let userId = res.graphql.user.id

  let after = null, has_next = true
  while (has_next) {
    await fetch(`https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=` + encodeURIComponent(JSON.stringify({
      id: userId,
      include_reel: true,
      fetch_mutual: true,
      first: 50,
      after: after
    }))).then(res => res.json()).then(res => {
      has_next = res.data.user.edge_followed_by.page_info.has_next_page
      after = res.data.user.edge_followed_by.page_info.end_cursor
      followers = followers.concat(res.data.user.edge_followed_by.edges.map(({node}) => {
        return {
          username: node.username,
          full_name: node.full_name
        }
      }))
    })
  }
  console.log('Followers', followers)

  has_next = true
  after = null
  while (has_next) {
    await fetch(`https://www.instagram.com/graphql/query/?query_hash=d04b0a864b4b54837c0d870b0e77e076&variables=` + encodeURIComponent(JSON.stringify({
      id: userId,
      include_reel: true,
      fetch_mutual: true,
      first: 50,
      after: after
    }))).then(res => res.json()).then(res => {
      has_next = res.data.user.edge_follow.page_info.has_next_page
      after = res.data.user.edge_follow.page_info.end_cursor
      followings = followings.concat(res.data.user.edge_follow.edges.map(({node}) => {
        return {
          username: node.username,
          full_name: node.full_name
        }
      }))
    })
  }
  console.log('Followings', followings)
} catch (err) {
  console.log('Invalid username')
}

Add a Primary Key (code below)

Run the correct delete (code below)

Consider WHY you woudln't want to keep that primary key.

Assuming MSSQL or compatible:

ALTER TABLE Employee ADD EmployeeID int identity(1,1) PRIMARY KEY;

WHILE EXISTS (SELECT COUNT(*) FROM Employee GROUP BY EmpID, EmpSSN HAVING COUNT(*) > 1)
BEGIN
    DELETE FROM Employee WHERE EmployeeID IN 
    (
        SELECT MIN(EmployeeID) as [DeleteID]
        FROM Employee
        GROUP BY EmpID, EmpSSN
        HAVING COUNT(*) > 1
    )
END

You can also take advantage of the built-in Service Parameters system, which lets you isolate or reuse the value:

# app/config/parameters.yml
parameters:
    ga_tracking: UA-xxxxx-x

# app/config/config.yml
twig:
    globals:
        ga_tracking: "%ga_tracking%"

Now, the variable ga_tracking is available in all Twig templates:

<p>The google tracking code is: {{ ga_tracking }}</p>

The parameter is also available inside the controllers:

$this->container->getParameter('ga_tracking');

You can also define a service as a global Twig variable (Symfony2.2+):

# app/config/config.yml
twig:
    # ...
    globals:
        user_management: "@acme_user.user_management"

http://symfony.com/doc/current/templating/global_variables.html

If the global variable you want to set is more complicated - say an object - then you won't be able to use the above method. Instead, you'll need to create a Twig Extension and return the global variable as one of the entries in the getGlobals method.

You need to provide a body for the get; portion as well as the set; portion of the property.

I suspect you want this to be:

private int _hour; // backing field
private int Hour
    {
        get { return _hour; }
        set
        {
            //make sure hour is positive
            if (value < MIN_HOUR)
            {
                _hour = 0;
                MessageBox.Show("Hour value " + value.ToString() + " cannot be negative. Reset to " + MIN_HOUR.ToString(),
                "Invalid Hour", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
            }
            else
            {
                //take the modulus to ensure always less than 24 hours
                //works even if the value is already within range, or value equal to 24
                _hour = value % MAX_HOUR;
            }
        }
    }

That being said, I'd also consider making this code simpler. It's probably is better to use exceptions rather than a MessageBox inside of your property setter for invalid input, as it won't tie you to a specific UI framework.

If that is inappropriate, I would recommend converting this to a method instead of using a property setter. This is especially true since properties have an implicit expectation of being "lightweight"- and displaying a MessageBox to the user really violates that expectation.

There isn't much else to add other than what the docs say. If you want to dump the JSON into a file/socket or whatever, then you should go with dump(). If you only need it as a string (for printing, parsing or whatever) then use dumps() (dump string)

As mentioned by Antti Haapala in this answer, there are some minor differences on the ensure_ascii behaviour. This is mostly due to how the underlying write() function works, being that it operates on chunks rather than the whole string. Check his answer for more details on that.

json.dump()

Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object

If ensure_ascii is False, some chunks written to fp may be unicode instances

json.dumps()

Serialize obj to a JSON formatted str

If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance

May be You are not registering the Controllers. Try below code:

Step 1. Write your own controller factory class ControllerFactory :DefaultControllerFactory by implementing defaultcontrollerfactory in models folder

  public class ControllerFactory :DefaultControllerFactory
    {
    protected override IController GetControllerInstance(RequestContext         requestContext, Type controllerType)
        {
            try
            {
                if (controllerType == null)
                    throw new ArgumentNullException("controllerType");

                if (!typeof(IController).IsAssignableFrom(controllerType))
                    throw new ArgumentException(string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");

                return MvcUnityContainer.Container.Resolve(controllerType) as IController;
            }
            catch
            {
                return null;
            }

        }
        public static class MvcUnityContainer
        {
            public static UnityContainer Container { get; set; }
        }
    }

Step 2:Regigster it in BootStrap: inBuildUnityContainer method

private static IUnityContainer BuildUnityContainer()
    {
      var container = new UnityContainer();

      // register all your components with the container here
      // it is NOT necessary to register your controllers

      // e.g. container.RegisterType<ITestService, TestService>();    
      //RegisterTypes(container);
      container = new UnityContainer();
      container.RegisterType<IProductRepository, ProductRepository>();


      MvcUnityContainer.Container = container;
      return container;
    }

Step 3: In Global Asax.

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
            Bootstrapper.Initialise();
            ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));

        }

And you are done

you can use commons csv to convert into CSV format. or use POI to convert into xls. if you need helper to convert into xls, you can use jxls, it can convert java bean (or list) into excel with expression language.

Basically, the json doc maybe is a json array, right? so it will be same. the result will be list, and you just write the property that you want to display in excel format that will be read by jxls. See http://jxls.sourceforge.net/reference/collections.html

If the problem is the json can't be read in the jxls excel property, just serialize it into collection of java bean first.

This error can also happen if you pass a key word argument for which one of the keys is similar (has same string name) to a positional argument.

>>> class Foo():
...     def bar(self, bar, **kwargs):
...             print(bar)
...

"fire" has been accepted into the 'bar' argument. And yet there is another 'bar' argument present in kwargs.

You would have to remove the keyword argument from the kwargs before passing it to the method.

I found 3 ways to solve this.

1. Debug on an Android 4.0 device (I ran it on an android Lollipop device before).
2. Click the restart button in DDMS.
3. Launch Android Device Monitor , and you will find log in logcat. Good luck ~

You can use pathlib.

For Python 3.5 and above:

from pathlib import Path
contents = Path(file_path).read_text()

For older versions of Python use pathlib2:

$ pip install pathlib2

Then:

from pathlib2 import Path
contents = Path(file_path).read_text()

This is the actual read_text implementation:

def read_text(self, encoding=None, errors=None):
    """
    Open the file in text mode, read it, and close the file.
    """
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
        return f.read()

PermGen stands for Permanent Generation.

Here is a brief blurb on DDJ

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

sudo apt-get install openjfx

I suppose the language is C, or C++...

strtok, IIRC, replace separators with \0. That's what it cannot use a const string. To workaround that "quickly", if the string isn't huge, you can just strdup() it. Which is wise if you need to keep the string unaltered (what the const suggest...).

On the other hand, you might want to use another tokenizer, perhaps hand rolled, less violent on the given argument.

Just add these lines in your styles.xml file

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- This is used for statusbar color. -->
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <!-- This is used for statusbar content color. If statusbarColor is light, use "true" otherwise use "false"-->
    <item name="android:windowLightStatusBar">false</item>
</style>

By design, getRequestURL() gives you the full URL, missing only the query string.

In HttpServletRequest, you can get individual parts of the URI using the methods below:

// Example: http://myhost:8080/people?lastname=Fox&age=30

String uri = request.getScheme() + "://" +   // "http" + "://
             request.getServerName() +       // "myhost"
             ":" +                           // ":"
             request.getServerPort() +       // "8080"
             request.getRequestURI() +       // "/people"
             "?" +                           // "?"
             request.getQueryString();       // "lastname=Fox&age=30"

• .getScheme() will give you "https" if it was a https://domain request.
• .getServerName() gives domain on http(s)://domain.
• .getServerPort() will give you the port.

Use the snippet below:

String uri = request.getScheme() + "://" +
             request.getServerName() + 
             ("http".equals(request.getScheme()) && request.getServerPort() == 80 || "https".equals(request.getScheme()) && request.getServerPort() == 443 ? "" : ":" + request.getServerPort() ) +
             request.getRequestURI() +
            (request.getQueryString() != null ? "?" + request.getQueryString() : "");

This snippet above will get the full URI, hiding the port if the default one was used, and not adding the "?" and the query string if the latter was not provided.

Proxied requests

Note, that if your request passes through a proxy, you need to look at the X-Forwarded-Proto header since the scheme might be altered:

request.getHeader("X-Forwarded-Proto")

Also, a common header is X-Forwarded-For, which show the original request IP instead of the proxys IP.

request.getHeader("X-Forwarded-For")

If you are responsible for the configuration of the proxy/load balancer yourself, you need to ensure that these headers are set upon forwarding.

You could use filter_var to remove all illegal characters except digits, dot and the comma.

• The FILTER_SANITIZE_NUMBER_FLOAT filter is used to remove all non-numeric character from the string.
• FILTER_FLAG_ALLOW_FRACTION is allowing fraction separator " . "
• The purpose of FILTER_FLAG_ALLOW_THOUSAND to get comma from the string.

Code

$var1 = '12.322,11T';

echo filter_var($var1, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);

Output

12.322,11

The code posted by Owen can tell you the information mentioned by a number of the other answers here:

public void simpleExample ()
{
    FileInputStream fis = new FileInputStream ("mytest.class");
    parseJavaClassFile ( fis );
}
protected void parseJavaClassFile ( InputStream classByteStream ) throws Exception
{
    DataInputStream dataInputStream = new DataInputStream ( classByteStream );
    magicNumber = dataInputStream.readInt();
    if ( magicNumber == 0xCAFEBABE )
    {
        int minorVer = dataInputStream.readUnsignedShort();
        int majorVer = dataInputStream.readUnsignedShort();
        // do something here with major & minor numbers
    }
}

The difference between Func and Action is simply whether you want the delegate to return a value (use Func) or not (use Action).

Func is probably most commonly used in LINQ - for example in projections:

 list.Select(x => x.SomeProperty)

or filtering:

 list.Where(x => x.SomeValue == someOtherValue)

or key selection:

 list.Join(otherList, x => x.FirstKey, y => y.SecondKey, ...)

Action is more commonly used for things like List<T>.ForEach: execute the given action for each item in the list. I use this less often than Func, although I do sometimes use the parameterless version for things like Control.BeginInvoke and Dispatcher.BeginInvoke.

Predicate is just a special cased Func<T, bool> really, introduced before all of the Func and most of the Action delegates came along. I suspect that if we'd already had Func and Action in their various guises, Predicate wouldn't have been introduced... although it does impart a certain meaning to the use of the delegate, whereas Func and Action are used for widely disparate purposes.

Predicate is mostly used in List<T> for methods like FindAll and RemoveAll.

faster to read than non cluster as data is physically storted in index order we can create only one per table.(cluster index)

quicker for insert and update operation than a cluster index. we can create n number of non cluster index.

I had the same issue. Root cause was using custom deserializer without default constructor.

Yes there is a major difference between the two methods Use delete_all if you want records to be deleted quickly without model callbacks being called

If you care about your models callbacks then use destroy_all

From the official docs

http://apidock.com/rails/ActiveRecord/Base/destroy_all/class

destroy_all(conditions = nil) public

Destroys the records matching conditions by instantiating each record and calling its destroy method. Each object’s callbacks are executed (including :dependent association options and before_destroy/after_destroy Observer methods). Returns the collection of objects that were destroyed; each will be frozen, to reflect that no changes should be made (since they can’t be persisted).

Note: Instantiation, callback execution, and deletion of each record can be time consuming when you’re removing many records at once. It generates at least one SQL DELETE query per record (or possibly more, to enforce your callbacks). If you want to delete many rows quickly, without concern for their associations or callbacks, use delete_all instead.

I know this is too late for sure, but, this could help someone as well.

In my case, i found that the source file is being used by another process which was restricting from copying to the destination. I found that by using command prompt ( just copy paste the post build command to the command prompt and executed gave me the error info).

Make sure that you can copy from the command prompt,

Just before executing the query: alter session set NLS_DATE_FORMAT = "DD.MM.YYYY HH24:MI:SS"; or whichever format you are giving the information to the date function. This should fix the ORA error

The guaranteed, rock solid way to force a UIView to re-render is [myView setNeedsDisplay]. If you're having trouble with that, you're likely running into one of these issues:

• You're calling it before you actually have the data, or your -drawRect: is over-caching something.

• You're expecting the view to draw at the moment you call this method. There is intentionally no way to demand "draw right now this very second" using the Cocoa drawing system. That would disrupt the entire view compositing system, trash performance and likely create all kinds of artifacting. There are only ways to say "this needs to be drawn in the next draw cycle."

If what you need is "some logic, draw, some more logic," then you need to put the "some more logic" in a separate method and invoke it using -performSelector:withObject:afterDelay: with a delay of 0. That will put "some more logic" after the next draw cycle. See this question for an example of that kind of code, and a case where it might be needed (though it's usually best to look for other solutions if possible since it complicates the code).

If you don't think things are getting drawn, put a breakpoint in -drawRect: and see when you're getting called. If you're calling -setNeedsDisplay, but -drawRect: isn't getting called in the next event loop, then dig into your view hierarchy and make sure you're not trying to outsmart is somewhere. Over-cleverness is the #1 cause of bad drawing in my experience. When you think you know best how to trick the system into doing what you want, you usually get it doing exactly what you don't want.

I stumbled upon a situation where I have a small component I want to reuse, and added some code in a reusable view itself(it's really not much more than a button that opens a PopoverController).

While this works fine in the iPad (the UIPopoverController presents itself, therefor needs no reference to a UIViewController), getting the same code to work means suddenly referencing your presentViewController from your UIViewController. Kinda inconsistent right?

Like mentioned before, it's not the best approach to have logic in your UIView. But it felt really useless to wrap the few lines of code needed in a separate controller.

Either way, here's a swift solution, which adds a new property to any UIView:

extension UIView {

    var viewController: UIViewController? {

        var responder: UIResponder? = self

        while responder != nil {

            if let responder = responder as? UIViewController {
                return responder
            }
            responder = responder?.nextResponder()
        }
        return nil
    }
}

Extend LinearLayout/RelativeLayout and use it straight on the XML

package com.pkg_name ;
...imports...
public class LinearLayoutOutlined extends LinearLayout {
    Paint paint;    

    public LinearLayoutOutlined(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
        setWillNotDraw(false) ;
        paint = new Paint();
    }
    public LinearLayoutOutlined(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
        setWillNotDraw(false) ;
        paint = new Paint();
    }
    @Override
    protected void onDraw(Canvas canvas) {
        /*
        Paint fillPaint = paint;
        fillPaint.setARGB(255, 0, 255, 0);
        fillPaint.setStyle(Paint.Style.FILL);
        canvas.drawPaint(fillPaint) ;
        */

        Paint strokePaint = paint;
        strokePaint.setARGB(255, 255, 0, 0);
        strokePaint.setStyle(Paint.Style.STROKE);
        strokePaint.setStrokeWidth(2);  
        Rect r = canvas.getClipBounds() ;
        Rect outline = new Rect( 1,1,r.right-1, r.bottom-1) ;
        canvas.drawRect(outline, strokePaint) ;
    }

}

When working on an important code update, if you really need an intermediate safepoint you might just do:

git commit -am'.'

or shorter:

git commit -am.

You can use a CASE statement:

SELECT count(id), 
    SUM(hour) as totHour, 
    SUM(case when kind = 1 then 1 else 0 end) as countKindOne

What is the target platform of your application? I think you should set the platform to x86, do not set it to Any CPU.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

table tr td:nth-child(2) {
    background: #ccc;
}

Working example: http://jsfiddle.net/gqr3J/

Did find the answer on my own. My problem was, that i use two temporary tables for a join and create the second one out of the first one. But the Index was not copied during creation...

CREATE TEMPORARY TABLE tmpLivecheck (tmpid INTEGER NOT NULL AUTO_INCREMENT, PRIMARY    
KEY(tmpid), INDEX(tmpid))
SELECT * FROM tblLivecheck_copy WHERE tblLivecheck_copy.devId = did;

CREATE TEMPORARY TABLE tmpLiveCheck2 (tmpid INTEGER NOT NULL, PRIMARY KEY(tmpid), 
INDEX(tmpid))  
SELECT * FROM tmpLivecheck;

... solved my problem.

Greetings...

You should create a ModelForm (docs), which has a field that uses the PasswordInput widget from the forms library.

It would look like this:

models.py

from django import models
class User(models.Model):
    username = models.CharField(max_length=100)
    password = models.CharField(max_length=50)

forms.py (not views.py)

from django import forms
class UserForm(forms.ModelForm):
    class Meta:
        model = User
        widgets = {
        'password': forms.PasswordInput(),
    }

For more about using forms in a view, see this section of the docs.

Leaving another way here

git branch newbranch
git checkout master 
git merge newbranch 

If your simple test page is located on other protocol/domain/port than your hello world node.js example you are doing cross-domain requests and violating same origin policy therefore your jQuery ajax calls (get and load) are failing silently. To get this working cross-domain you should use JSONP based format. For example node.js code:

var http = require('http');

http.createServer(function (req, res) {
    console.log('request received');
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('_testcb(\'{"message": "Hello world!"}\')');
}).listen(8124);

and client side JavaScript/jQuery:

$(document).ready(function() {
    $.ajax({
        url: 'http://192.168.1.103:8124/',
        dataType: "jsonp",
        jsonpCallback: "_testcb",
        cache: false,
        timeout: 5000,
        success: function(data) {
            $("#test").append(data);
        },
        error: function(jqXHR, textStatus, errorThrown) {
            alert('error ' + textStatus + " " + errorThrown);
        }
    });
});

There are also other ways how to get this working, for example by setting up reverse proxy or build your web application entirely with framework like express.
