I found that when mixed with PCL libraries the above problem presented itself, and whilst it is true that the WindowsBase library contains System.IO.Packaging I was using the OpenXMLSDK-MOT 2.6.0.0 library which itself provides it's own copy of the physical System.IO.Packaging library. The reference that was missing for me could be found as follows in the csharp project

<Reference Include="System.IO.Packaging, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
  <HintPath>..\..\..\..\packages\OpenXMLSDK-MOT.2.6.0.0\lib\System.IO.Packaging.dll</HintPath>
  <Private>True</Private>
</Reference>

I downgraded my version of the XMLSDK to 2.6 which then seemed to fix this problem up for me. But you can see there is a physical assembly System.IO.Packaging.dll

IB and Swift

Given the flowing layout where yellow is the superview and red, green, and blue are sibling subviews of yellow,

the goal is to move a subview (let's say green) to the top.

In Interface Builder

In the Interface Builder all you need to do is drag the view you want showing on the top to the bottom of the list in the Documents Outline.

Alternatively, you can select the view and then in the menu go to Editor > Arrange > Send to Front.

In Swift

There are a couple of different ways to do this programmatically.

Method 1

yellowView.bringSubviewToFront(greenView)

• This method is the programmatic equivalent of the IB answer above.

• It only works if the subviews are siblings of each other.

• An array of the subviews is contained in yellowView.subviews. Here, bringSubviewToFront moves the greenView from index 0 to 2. This can be observed with

    print(yellowView.subviews.indexOf(greenView))
  

Method 2

greenView.layer.zPosition = 1

• This method just moves the 3D position of the layer higher (closer to the user) on the z-axis. Since the default is 0 for all the other views, the result is that the greenView looks like it is on top. However, it still remains at index 0 of the yellowView.subviews array. This can cause some unexpected results, though, because things like tap events will still go first to the view with the highest index number. For that reason, it might be better to go with Method 1 above.
• The zPosition could be set to CGFloat.greatestFiniteMagnitude (CGFloat(FLT_MAX) in older versions of Swift) to ensure that it is on top.

This has been moved to a new location now -- and please use the below site for updates.

Why is it necessary for an interface to be "declared" abstract?

It's not.

public abstract interface Interface {
       \___.__/
           |
           '----> Neither this...

    public void interfacing();
    public abstract boolean interfacing(boolean really);
           \___.__/
               |
               '----> nor this, are necessary.
}

Interfaces and their methods are implicitly abstract and adding that modifier makes no difference.

Is there other rules that applies with an abstract interface?

No, same rules apply. The method must be implemented by any (concrete) implementing class.

If abstract is obsolete, why is it included in Java? Is there a history for abstract interface?

Interesting question. I dug up the first edition of JLS, and even there it says "This modifier is obsolete and should not be used in new Java programs".

Okay, digging even further... After hitting numerous broken links, I managed to find a copy of the original Oak 0.2 Specification (or "manual"). Quite interesting read I must say, and only 38 pages in total! :-)

Under Section 5, Interfaces, it provides the following example:

public interface Storing {
    void freezeDry(Stream s) = 0;
    void reconstitute(Stream s) = 0;
}

And in the margin it says

In the future, the " =0" part of declaring methods in interfaces may go away.

Assuming =0 got replaced by the abstract keyword, I suspect that abstract was at some point mandatory for interface methods!

From Stroustrup's speech at "Going Native 2012":

       enum { m=M, kg=K, s=S };
};

template<typename Unit> // a magnitude with a unit 
struct Value {
       double val;   // the magnitude 
       explicit Value(double d) : val(d) {} // construct a Value from a double 
};

using Speed = Value<Unit<1,0,-1>>;  // meters/second type
using Acceleration = Value<Unit<1,0,-2>>;  // meters/second/second type
using Second = Unit<0,0,1>;  // unit: sec
using Second2 = Unit<0,0,2>; // unit: second*second 

constexpr Value<Second> operator"" s(long double d)
   // a f-p literal suffixed by ‘s’
{
  return Value<Second> (d);  
}   

constexpr Value<Second2> operator"" s2(long double d)
  // a f-p literal  suffixed by ‘s2’ 
{
  return Value<Second2> (d); 
}

Speed sp1 = 100m/9.8s; // very fast for a human 
Speed sp2 = 100m/9.8s2; // error (m/s2 is acceleration)  
Speed sp3 = 100/9.8s; // error (speed is m/s and 100 has no unit) 
Acceleration acc = sp1/0.5s; // too fast for a human

var startTime = new Date('2012/10/09 12:00'); 
var endTime = new Date('2013/10/09 12:00');
var difference = endTime.getTime() - startTime.getTime(); // This will give difference in milliseconds
var resultInMinutes = Math.round(difference / 60000);

If you are on .NET 4.0 use a Tuple:

lookup = new Dictionary<Tuple<TypeA, TypeB, TypeC>, string>();

If not you can define a Tuple and use that as the key. The Tuple needs to override GetHashCode, Equals and IEquatable:

struct Tuple<T, U, W> : IEquatable<Tuple<T,U,W>>
{
    readonly T first;
    readonly U second;
    readonly W third;

    public Tuple(T first, U second, W third)
    {
        this.first = first;
        this.second = second;
        this.third = third;
    }

    public T First { get { return first; } }
    public U Second { get { return second; } }
    public W Third { get { return third; } }

    public override int GetHashCode()
    {
        return first.GetHashCode() ^ second.GetHashCode() ^ third.GetHashCode();
    }

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
        {
            return false;
        }
        return Equals((Tuple<T, U, W>)obj);
    }

    public bool Equals(Tuple<T, U, W> other)
    {
        return other.first.Equals(first) && other.second.Equals(second) && other.third.Equals(third);
    }
}

ORA-12154: TNS:could not resolve the connect identifier specified
Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured. For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.
Action:

• If you are using local naming (TNSNAMES.ORA file):

• Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA)

• Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible.

• Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file.

• Make sure there are no syntax errors anywhere in the TNSNAMES.ORA file. Look for unmatched parentheses or stray characters. Errors in a TNSNAMES.ORA file may make it unusable.

• If you are using directory naming:

• Verify that "LDAP" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).

• Verify that the LDAP directory server is up and that it is accessible.

• Verify that the net service name or database name used as the connect identifier is configured in the directory.

• Verify that the default context being used is correct by specifying a fully qualified net service name or a full LDAP DN as the connect identifier

• If you are using easy connect naming:

• Verify that "EZCONNECT" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).

• Make sure the host, port and service name specified are correct.

• Try enclosing the connect identifier in quote marks. See the Oracle Net Services Administrators Guide or the Oracle operating system specific guide for more information on naming.

This happens because you trying to run service at the same port and there is an already running application.

This can happen because your service is not stopped in the process stack. Then you just have to kill this process.

There is no need to install anything here is the one line command to kill all running python processes.

for Linux based OS:

Bash:

kill -9 $(ps -A | grep python | awk '{print $1}')

Fish:

kill -9 (ps -A | grep python | awk '{print $1}')

Ups! I was thinking in delphi, there must be something similar in all languages.

The accepted answer shows the correct way to setState but it does not lead to a well functioning select box.

import React, { useState } from "react"; 
import ReactDOM from "react-dom";

const initialValue = { id: 0,value: " --- Select a State ---" };

const options = [
    { id: 1, value: "Alabama" },
    { id: 2, value: "Georgia" },
    { id: 3, value: "Tennessee" }
];

const StateSelector = () => {   
   const [ selected, setSelected ] = useState(initialValue);  

     return (
       <div>
          <label>Select a State:</label>
          <select value={selected}>
            {selected === initialValue && 
                <option disabled value={initialValue}>{initialValue.value}</option>}
            {options.map((localState, index) => (
               <option key={localState.id} value={localState}>
                   {localState.value}
               </option>
             ))}
          </select>
        </div>
      ); 
};

const rootElement = document.getElementById("root");
ReactDOM.render(<StateSelector />, rootElement);

On the event of onClick

this.state={
  title:''
}

sendthru=()=>{
  document.getElementByid('inputname').value = '';
  this.setState({
     title:''
})
}

<input type="text" id="inputname" className="form-control" ref={el => this.inputTitle = el} />   
<button className="btn btn-info" onClick={this.sendthru}>Add</button>

Subsetting the data and combining them back is unnecessary. So are loops since those operations are vectorized. From your previous edit, I'm guessing you are doing all of this to make bubble plots. If that is correct, perhaps the example below will help you. If this is way off, I can just delete the answer.

library(ggplot2)
# let's look at the included dataset named trees.
# ?trees for a description
data(trees)
ggplot(trees,aes(Height,Volume)) + geom_point(aes(size=Girth))
# Great, now how do we color the bubbles by groups?
# For this example, I'll divide Volume into three groups: lo, med, high
trees$set[trees$Volume<=22.7]="lo"
trees$set[trees$Volume>22.7 & trees$Volume<=45.4]="med"
trees$set[trees$Volume>45.4]="high"

ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth))


# Instead of just circles scaled by Girth, let's also change the symbol
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=set))

# Now let's choose a specific symbol for each set. Full list of symbols at ?pch
trees$symbol[trees$Volume<=22.7]=1
trees$symbol[trees$Volume>22.7 & trees$Volume<=45.4]=2
trees$symbol[trees$Volume>45.4]=3

ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=symbol))

In Drupal

I have a Drupal 6 site. I was on the admin "modules" page, and noticed the tables had this exact feature!

Looking at the code, it seems to be implemented by a file called tableheader.js. It applies the feature on all tables with the class sticky-enabled.

For a Drupal site, I'd like to be able to make use of that tableheader.js module as-is for user content. tableheader.js doesn't seem to be present on user content pages in Drupal. I posted a forum message to ask how to modify the Drupal theme so it's available. According to a response, tableheader.js can be added to a Drupal theme using drupal_add_js() in the theme's template.php as follows:

drupal_add_js('misc/tableheader.js', 'core');

I see the status field on the jqXhr object, here is a fiddle with it working:

http://jsfiddle.net/magicaj/55HQq/3/

$.ajax({
    //...        
    success: function(data, textStatus, xhr) {
        console.log(xhr.status);
    },
    complete: function(xhr, textStatus) {
        console.log(xhr.status);
    } 
});

As mentioned by Camila Macedo - you have to explicitly point the java version for compiler-plugin. For spring boot you can do that by next property:

  <properties>
    <java.version>1.8</java.version>
    <maven.compiler.release>8</maven.compiler.release>
  </properties>

Mongoose basically wraps mongodb's api to give you a pseudo relational db api so queries are not going to be exactly like mongodb queries. Mongoose findOne query returns a query object, not a document. You can either use a callback as the solution suggests or as of v4+ findOne returns a thenable so you can use .then or await/async to retrieve the document.

// thenables
Auth.findOne({nick: 'noname'}).then(err, result) {console.log(result)};
Auth.findOne({nick: 'noname'}).then(function (doc) {console.log(doc)});

// To use a full fledge promise you will need to use .exec()
var auth = Auth.findOne({nick: 'noname'}).exec();
auth.then(function (doc) {console.log(doc)});

// async/await
async function auth() {
  const doc = await Auth.findOne({nick: 'noname'}).exec();
  return doc;
}
auth();

See the docs if you would like to use a third party promise library.

I had the same problem :) Verify the "Source code" folder on the "Solution Explorer", if it doesn't contain any "source code" file then :

Right click on "Source code" > Add > Existing Item > Choose the file You want to build and run.

Good luck ;)

I hate to post my own answer, but some answers recently have ignored the solution I posted in my own question, suggesting approaches that are nothing short of foolhardy.

In short - you do not need to edit any Windows user account privileges at all. Doing so only introduces risk. The process is entirely managed in IIS using inherited privileges.

Applying Modify/Write Permissions to the Correct User Account

1. Right-click the domain when it appears under the Sites list, and choose Edit Permissions

   

   Under the Security tab, you will see MACHINE_NAME\IIS_IUSRS is listed. This means that IIS automatically has read-only permission on the directory (e.g. to run ASP.Net in the site). You do not need to edit this entry.

   

2. Click the Edit button, then Add...

3. In the text box, type IIS AppPool\MyApplicationPoolName, substituting MyApplicationPoolName with your domain name or whatever application pool is accessing your site, e.g. IIS AppPool\mydomain.com

   

4. Press the Check Names button. The text you typed will transform (notice the underline):

   

5. Press OK to add the user

6. With the new user (your domain) selected, now you can safely provide any Modify or Write permissions

   

array_splice($array, array_search(array_value, $array), 1);

My version for a directive that uses jqplot to plot the data once it becomes available:

    app.directive('lineChart', function() {
        $.jqplot.config.enablePlugins = true;

        return function(scope, element, attrs) {
            scope.$watch(attrs.lineChart, function(newValue, oldValue) {
                if (newValue) {
                    // alert(scope.$eval(attrs.lineChart));
                    var plot = $.jqplot(element[0].id, scope.$eval(attrs.lineChart), scope.$eval(attrs.options));
                }
            });
        }
});

public static final long SECOND_IN_MILLIS = 1000;
public static final long MINUTE_IN_MILLIS = SECOND_IN_MILLIS * 60;
public static final long HOUR_IN_MILLIS = MINUTE_IN_MILLIS * 60;
public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;

You could cast int but I would recommend using long.

Your code seems right, check if you have fopen wrappers enabled (allow_url_fopen = On on php.ini)

Also, as mentioned by other answers, you should provide a properly encoded URI or encode it using urlencode() function. You should also check if there is any error fetching the XML string and if there is any parsing error, which you can output using libxml_get_errors() as follows:

<?php
if (($response_xml_data = file_get_contents($map_url))===false){
    echo "Error fetching XML\n";
} else {
   libxml_use_internal_errors(true);
   $data = simplexml_load_string($response_xml_data);
   if (!$data) {
       echo "Error loading XML\n";
       foreach(libxml_get_errors() as $error) {
           echo "\t", $error->message;
       }
   } else {
      print_r($data);
   }
}
?>

If the problem is you can't fetch the XML code maybe it's because you need to include some custom headers in your request, check how to use stream_context_create() to create a custom stream context for use when calling file_get_contents() on example 4 at http://php.net/manual/en/function.file-get-contents.php

Using a double-tilde (double bitwise NOT) - ~~ - does some interesting things in JavaScript. For instance you can use it instead of Math.floor or even as an alternative to parseInt("123", 10)! It's been discussed a lot over the web, so I won't go in why it works here, but if you're interested: What is the "double tilde" (~~) operator in JavaScript?

We can exploit this property of a double-tilde to convert NaN to a number, and happily that number is zero!

console.log(~~NaN); // 0

Uncheck this in Windows Explorer.

The %d and %s string formatting "commands" are used to format strings. The %d is for numbers, and %s is for strings.

For an example:

print("%s" % "hi")

To pass multiple arguments:

print("%s %s %s%d" % ("hi", "there", "user", 123456)) will return hi there user123456

It's not pretty, but this is how I did it granted you have this option installed on your SQL 2008 R2 install..

1) Right click database in SQL Server 2008 R2 "Tasks".. "Generate scripts" in the wizard, select the entire database and objects in first step. On the "Set Scripting Options" step you should see a button "Advanced" , select this and make sure you select "Script for Server Version" = SQL Server 2008" not R2 version. This is a crucial step, because "import data" by itself does not bring along all the primary keys, constriants and any other objects like stored procedures."

2) Run the SQL script generated on the new install or database instance SQL Express or SQL Server 2008 using the query window or open saved .sql script and execute and you should see the new database.

3) Now right click on the new database and select "Tasks".. "Import Data.." choose source as the R2 database and the destination as the new database. "Copy data from one or more tables or views", select the top checkbox to select all tables and then next step, run the package and you should have everything on a older version. This should work for going back to a 2005 version as well. Hope this helps someone out.

As of mid-2015, I believe this is the best solution:

<input type="number" pattern="[0-9]*" inputmode="numeric">

This will give you the numeric keypad on both Android and iOS:

It also gives you the expected desktop behavior with the up/down arrow buttons and keyboard friendly up/down arrow key incrementing:

Try it in this code snippet:

<form>_x000D_
  <input type="number" pattern="[0-9]*" inputmode="numeric">_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

By combining both type="number" and pattern="[0-9]*, we get a solution that works everywhere. And, its forward compatible with the future HTML 5.1 proposed inputmode attribute.

Note: Using a pattern will trigger the browser's native form validation. You can disable this using the novalidate attribute, or you can customize the error message for a failed validation using the title attribute.

If you need to be able to enter leading zeros, commas, or letters - for example, international postal codes - check out this slight variant.

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

An example here from a sample test WAMP server database:-

DEFINITIVELY, a long answer and alot of scrolling. Also I struggled hard to pass the output of the queries to a text file. Here is how to do that without using the annoying into outfile thing-

tee E:/sqllogfile.txt;

And when you are done, stop the logging-

tee off;

Hope it adds more clarity.

By invoking its toString() method.

Returns a string containing the characters in this sequence in the same order as this sequence. The length of the string will be the length of this sequence.

Here's an extension method for converting a Bitmap to BitmapImage.

    public static BitmapImage ToBitmapImage(this Bitmap bitmap)
    {
        using (var memory = new MemoryStream())
        {
            bitmap.Save(memory, ImageFormat.Png);
            memory.Position = 0;

            var bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.StreamSource = memory;
            bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
            bitmapImage.EndInit();
            bitmapImage.Freeze();

            return bitmapImage;
        }
    }

I tried the code:

tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

In the viewDidLoad section and xcode6 showed a warning. I have put a "self." in front of it and now it works fine. so the working code I use is:

self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

Q1:Could the time it takes for a transaction to execute make the associated process more likely to be flagged as a deadlock victim.

No. The SELECT is the victim because it had only read data, therefore the transaction has a lower cost associated with it so is chosen as the victim:

By default, the Database Engine chooses as the deadlock victim the session running the transaction that is least expensive to roll back. Alternatively, a user can specify the priority of sessions in a deadlock situation using the SET DEADLOCK_PRIORITY statement. DEADLOCK_PRIORITY can be set to LOW, NORMAL, or HIGH, or alternatively can be set to any integer value in the range (-10 to 10).

Q2. If I execute the select with a NOLOCK hint, will this remove the problem?

No. For several reasons:

• you should first try to eliminate the deadlock properly, by investigating the root cause
• dirty reads are inconsistent reads.
• the proper way to specify dirty reads is to use transaction isolation levels
• there is a much better solution: read committed snapshot.

Q3. I suspect that a datetime field that is checked as part of the WHERE clause in the select statement is causing the slow lookup time. Can I create an index based on this field? Is it advisable?

Probably. The cause of the deadlock is almost very likely to be a poorly indexed database.10 minutes queries are acceptable in such narrow conditions, that I'm 100% certain in your case is not acceptable.

With 99% confidence I declare that your deadlock is cased by a large table scan conflicting with updates. Start by capturing the deadlock graph to analyze the cause. You will very likely have to optimize the schema of your database. Before you do any modification, read this topic Designing Indexes and the sub-articles.

An abbreviated version of your code worked for me,

class Remote: NSObject {

    var data = NSMutableData()

    func connect(query:NSString) {
        var url =  NSURL.URLWithString("http://www.google.com")
        var request = NSURLRequest(URL: url)
        var conn = NSURLConnection(request: request, delegate: self, startImmediately: true)
    }


     func connection(didReceiveResponse: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
        println("didReceiveResponse")
    }

    func connection(connection: NSURLConnection!, didReceiveData conData: NSData!) {
        self.data.appendData(conData)
    }

    func connectionDidFinishLoading(connection: NSURLConnection!) {
        println(self.data)
    }


    deinit {
        println("deiniting")
    }
}

This is the code I used in the calling class,

class ViewController: UIViewController {

    var remote = Remote()


    @IBAction func downloadTest(sender : UIButton) {
        remote.connect("/apis")
    }

}

You didn't specify in your question where you had this code,

var remote = Remote()
remote.connect("/apis")

If var is a local variable, then the Remote class will be deallocated right after the connect(query:NSString) method finishes, but before the data returns. As you can see by my code, I usually implement reinit (or dealloc up to now) just to make sure when my instances go away. You should add that to your Remote class to see if that's your problem.

print((df.count(), len(df.columns)))

is easier for smaller datasets.

However if the dataset is huge, an alternative approach would be to use pandas and arrows to convert the dataframe to pandas df and call shape

spark.conf.set("spark.sql.execution.arrow.enabled", "true")
spark.conf.set("spark.sql.crossJoin.enabled", "true")
print(df.toPandas().shape)

It would be nice to be able to specify a port other than 3000, either as a command line parameter or an environment variable.

Right now, the process is pretty involved:

1. Run npm run eject
2. Wait for that to finish
3. Edit scripts/start.js and find/replace 3000 with whatever port you want to use
4. Edit config/webpack.config.dev.js and do the same
5. npm start

(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).

My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert() changed names to create() so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!

The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.

Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload class. This snippet assumes your auth code works where your service endpoint is DRIVE with a minimum auth scope of https://www.googleapis.com/auth/drive.file.

# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'

# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
    print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))

Better yet, rather than uploading to My Drive, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.

If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7

I think .myi you can repair from inside mysql.

If you see these type of error messages from MySQL: Database failed to execute query (query) 1016: Can't open file: 'sometable.MYI'. (errno: 145) Error Msg: 1034: Incorrect key file for table: 'sometable'. Try to repair it thenb you probably have a crashed or corrupt table.

You can check and repair the table from a mysql prompt like this:

check table sometable;
+------------------+-------+----------+----------------------------+
| Table | Op | Msg_type | Msg_text | 
+------------------+-------+----------+----------------------------+ 
| yourdb.sometable | check | warning | Table is marked as crashed | 
| yourdb.sometable | check | status | OK | 
+------------------+-------+----------+----------------------------+ 

repair table sometable;
+------------------+--------+----------+----------+ 
| Table | Op | Msg_type | Msg_text | 
+------------------+--------+----------+----------+ 
| yourdb.sometable | repair | status | OK | 
+------------------+--------+----------+----------+

and now your table should be fine:

check table sometable;
+------------------+-------+----------+----------+ 
| Table | Op | Msg_type | Msg_text |
+------------------+-------+----------+----------+ 
| yourdb.sometable | check | status | OK |
+------------------+-------+----------+----------+

To declare it:

var myArr = ["apples", "oranges", "bananas"];

To use it:

document.write("In my shopping basket I have " + myArr[0] + ", " + myArr[1] + ", and " + myArr[2]);

You may set both the main project and ProjectX's build output path to the same folder, then you can get all the dlls you need in that folder.

g++ -o foo foo.cpp

g++ --> Driver for cc1plus compiler

-o --> Indicates the output file (foo is the name of output file here. Can be any name)

foo.cpp --> Source file to be compiled

To execute the compiled file simply type

./foo

Add in your CSS:

 .ui-dialog { z-index: 1000 !important ;}

You should try removing the following code from your fragments

    try {
        mListener = (OnFragmentInteractionListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString()
                + " must implement OnFragmentInteractionListener");
    }

The interface/listener is a default created so that your activity and fragments can communicate easier

There are a couple of options. You can use the --device flag that use can use to access USB devices without --privileged mode:

docker run -t -i --device=/dev/ttyUSB0 ubuntu bash

Alternatively, assuming your USB device is available with drivers working, etc. on the host in /dev/bus/usb, you can mount this in the container using privileged mode and the volumes option. For example:

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb ubuntu bash

Note that as the name implies, --privileged is insecure and should be handled with care.

It's nice to have something to distinguish private vs. public variables, but I don't like '_' in general coding. If I can help it in new code, I avoid their use.

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

You should put your component between an enclosing tag, Which means:

// WRONG!

return (  
    <Comp1 />
    <Comp2 />
)

Instead:

// Correct

return (
    <div>
       <Comp1 />
       <Comp2 />
    </div>
)

Edit: Per Joe Clay's comment about the Fragments API

// More Correct

return (
    <React.Fragment>
       <Comp1 />
       <Comp2 />
    </React.Fragment>
)

// Short syntax

return (
    <>
       <Comp1 />
       <Comp2 />
    </>
)

<?php    
     $x = 1;

     for($x = 1; $x < 8; $x++) {
       $x = $x + 2;
       echo $x;
     };
?>

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

If the problem is not solved by above answer, check whether the Windows SDK version is 10.0.15063.0.

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0

After this rebuild the solution.  

This is one way:

class SomeClass {
    private static myStaticVariable = "whatever";
    private static __static_ctor = (() => { /* do static constructor stuff :) */ })();
}

__static_ctor here is an immediately invoked function expression. Typescript will output code to call it at the end of the generated class.

Update: For generic types in static constructors, which are no longer allowed to be referenced by static members, you will need an extra step now:

class SomeClass<T> {
    static myStaticVariable = "whatever";
    private ___static_ctor = (() => { var someClass:SomeClass<T> ; /* do static constructor stuff :) */ })();
    private static __static_ctor = SomeClass.prototype.___static_ctor();
}

In any case, of course, you could just call the generic type static constructor after the class, such as:

class SomeClass<T> {
    static myStaticVariable = "whatever";
    private __static_ctor = (() => { var example: SomeClass<T>; /* do static constructor stuff :) */ })();
}
SomeClass.prototype.__static_ctor();

Just remember to NEVER use this in __static_ctor above (obviously).

Like Snukker said, clients1.google.com is where the search suggestions come from. My guess is that they make a request to force clients1.google.com into your DNS cache before you need it, so you will have less latency on the first "real" request.

Google Chrome already does that for any links on a page, and (I think) when you type an address in the location bar. This seems like a way to get all browsers to do the same thing.

You've encountered a local time discontinuity:

When local standard time was about to reach Sunday, 1. January 1928, 00:00:00 clocks were turned backward 0:05:52 hours to Saturday, 31. December 1927, 23:54:08 local standard time instead

This is not particularly strange and has happened pretty much everywhere at one time or another as timezones were switched or changed due to political or administrative actions.

just to add some clarity, you need to stage changes with git add, then amend last commit:

git add /path/to/modified/files
git commit --amend --no-edit

This is especially useful for if you forgot to add some changes in last commit or when you want to add more changes without creating new commits by reusing the last commit.

I had the same Problem. I had start my Oracle TNS Listener, then it works normally again.

See LISTENER: TNS-12545 ... No such file or directory.

you can try to replace --> with a different string say, #END# and do search and replace with your editor when you wish to return the closing tags.

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.

Steps to resolve:

1. Open the Run window:

   Press windows+R

2. Open registry window:

   Type regedit and enter.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:

6. Create a new subkey of 1.8.

7. For 1.8 create a String Key with name JavaHome with the value of JRE home:

Others have given the 'Why', so I'll just add that your interface can define a Control; if you wrap it in a property:

public interface IView {
    Control Year { get; }
}


public Form : IView {
    public Control Year { get { return uxYear; } } //numeric text box or whatever
}

Enum to int: (int)Enum.FixedPeriods

Int to Enum: (Enum)myInt

For more complex type validations I like typeguard's approach of validating based on python type hint annotations:

from typeguard import check_type
from typing import List

try:
    check_type('mylist', [1, 2], List[int])
except TypeError as e:
    print(e)

You can perform very complex validations in very clean and readable fashion.

check_type('foo', [1, 3.14], List[Union[int, float]])
# vs
isinstance(foo, list) and all(isinstance(a, (int, float)) for a in foo) 

For Windows Subsystem for Linux (WSL) you'll need

apt install libswt-gtk-4-jni

If you don't have an OpenJDK 8 you'll also need

apt install openjdk-8-jdk

This will remove spaces only, matches the SQL functionality of rtrim(ltrim(myString))

Dim charstotrim() As Char = {" "c}
myString = myString .Trim(charstotrim) 

Try going Build Settings under "Target" and set "Allow Non-modular Includes in Framework Modules" to YES.

The real answer is that the location of the imports needs to be changed by the library owner. Those files ifaddrs.h, arpa/inet.h, sys/types.h are getting imported in a .h file in a framework, which Xcode doesn't like. The library maintainer should move them to a .m file. See for example this issue on GitHub, where AFNetworking fixed the same problem: https://github.com/AFNetworking/AFNetworking/issues/2205

JPA is indisputably a great simplification in the domain of enterprise applications built on the Java platform. As a developer who had to cope up with the intricacies of the old entity beans in J2EE I see the inclusion of JPA among the Java EE specifications as a big leap forward. However, while delving deeper into the JPA details I find things that are not so easy. In this article I deal with comparison of the EntityManager’s merge and persist methods whose overlapping behavior may cause confusion not only to a newbie. Furthermore I propose a generalization that sees both methods as special cases of a more general method combine.

Persisting entities

In contrast to the merge method the persist method is pretty straightforward and intuitive. The most common scenario of the persist method's usage can be summed up as follows:

"A newly created instance of the entity class is passed to the persist method. After this method returns, the entity is managed and planned for insertion into the database. It may happen at or before the transaction commits or when the flush method is called. If the entity references another entity through a relationship marked with the PERSIST cascade strategy this procedure is applied to it also."

The specification goes more into details, however, remembering them is not crucial as these details cover more or less exotic situations only.

Merging entities

In comparison to persist, the description of the merge's behavior is not so simple. There is no main scenario, as it is in the case of persist, and a programmer must remember all scenarios in order to write a correct code. It seems to me that the JPA designers wanted to have some method whose primary concern would be handling detached entities (as the opposite to the persist method that deals with newly created entities primarily.) The merge method's major task is to transfer the state from an unmanaged entity (passed as the argument) to its managed counterpart within the persistence context. This task, however, divides further into several scenarios which worsen the intelligibility of the overall method's behavior.

Instead of repeating paragraphs from the JPA specification I have prepared a flow diagram that schematically depicts the behaviour of the merge method:

So, when should I use persist and when merge?

persist

• You want the method always creates a new entity and never updates an entity. Otherwise, the method throws an exception as a consequence of primary key uniqueness violation.
• Batch processes, handling entities in a stateful manner (see Gateway pattern).
• Performance optimization

merge

• You want the method either inserts or updates an entity in the database.
• You want to handle entities in a stateless manner (data transfer objects in services)
• You want to insert a new entity that may have a reference to another entity that may but may not be created yet (relationship must be marked MERGE). For example, inserting a new photo with a reference to either a new or a preexisting album.

Try this code,

SELECT 
       * 
FROM 
       `customers` 
WHERE 
       (
          CONVERT 
               (`customer_code` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`customer_name` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`email_id` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`address1` USING utf8mb4) LIKE '%Mary%' 
          OR
          CONVERT(`report_sorting` USING utf8mb4) LIKE '%Mary%'
       )

There is another option that just entails using scikit-learn. As scikit's wiki describes, you can just use the following instructions:

from sklearn.model_selection import train_test_split

data, labels = np.arange(10).reshape((5, 2)), range(5)

data_train, data_test, labels_train, labels_test = train_test_split(data, labels, test_size=0.20, random_state=42)

This way you can keep in sync the labels for the data you're trying to split into training and test.

Solved it by removing the "Excluded" in the module setting (right click on project, "Open module settings").

Regular Expression for 0 to 100 with the decimal point.

setenv.sh is better, because you can easily port such configuration from one machine to another, or from one Tomcat version to another. catalina.sh changes from one version of Tomcat to another. But you can keep your setenv.sh unchanged with any version of Tomcat.

Another advantage is, that it is easier to track the history of your changes if you add it to your backup or versioning system. If you look how you setenv.sh changes along the history, you will see only your own changes. Whereas if you use catalina.sh, you will always see not only your changes, but also changes that came with each newer version of the Tomcat.

Do :

var data = new Array();
var tempData = new Array();

You can do a Runtime.getRuntime.exec(command) to relaunch the jar including classpath with args.

You can set the Authorization: Basic header only when you also have the WWW-Authenticate: Basic header on your 401 challenge.

But since you have WWW-Authenticate: Negotiate this should be the case for Kerberos based authentication.

As mentioned in a previous reply, this generally comes when compiling copy pasted code. If you have a bash shell, the following command generally works:

iconv -f utf-8 -t ascii//translit input.c > output.c

const string ua = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)";
Request.Headers["User-Agent"] = ua;
var httpWorkerRequestField = Request.GetType().GetField("_wr", BindingFlags.Instance | BindingFlags.NonPublic);
if (httpWorkerRequestField != null)
{
    var httpWorkerRequest = httpWorkerRequestField.GetValue(Request);
    var knownRequestHeadersField = httpWorkerRequest.GetType().GetField("_knownRequestHeaders", BindingFlags.Instance | BindingFlags.NonPublic);
    if (knownRequestHeadersField != null)
    {
        string[] knownRequestHeaders = (string[])knownRequestHeadersField.GetValue(httpWorkerRequest);
                    knownRequestHeaders[39] = ua;
    }

HTTP is stateless connection protocol, that is, the server cannot differentiate between different connections of different users.

Hence comes cookie, once a client connects first time to a server, the server generates a new session id, which later will be sent to the client as cookie value. And from now on, this session id will identify that client connection, because within each HTTP request it will see the appropriate session id inside cookies.

Now for each session id, the server keeps some data structure, which enables him to store data specific to user, this data structure you can abstractly call session.

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

You can use async import():

import fs = require('fs');

and then:

fs.readdir('./someDir', (err, files) => {
 files.forEach(file => {
  const module = import('./' + file).then(m =>
    m.callSomeMethod();
  );
  // or const module = await import('file')
  });
});

PHP does not do styling. You need to use html or css. Take a look at http://www.w3schools.com/tags/tag_hr.asp

In HTML 4.01, the

In HTML 4.01, the <hr> tag represents a horizontal rule.

The trunk directory is the directory that you're probably most familiar with, because it is used to hold the most recent changes. Your main codebase should be in trunk.

The branches directory is for holding your branches, whatever they may be.

The tags directory is basically for tagging a certain set of files. You do this for things like releases, where you want "1.0" to be these files at these revisions and "1.1" to be these files at these revisions. You usually don't modify tags once they're made. For more information on tags, see Chapter 4. Branching and Merging (in Version Control with Subversion).

Even, I was looking for the same regex but I wanted to include the all special character and blank spaces too. So here is the regex for that:

^[A-Za-z0-9\s$&+,:;=?@#|'<>.^*()%!-]{0,10}$

If you are making use of GUIDs this should be nice and easy, if you are looking for an integer ID, you will have to wait for another answer.

SELECT newId() AS ColId, Col1, Col2, Col3 FROM table1

The newId() will generate a new GUID for you that you can use as your automatically generated id column.

Use Datepart function: DATEPART(datepart, date)

E.g#

SELECT DatePart(@YourVar, hh)*60) + DatePart(@YourVar, mi)*60)

This will give you total time of day in minutes allowing you to compare more easily.

You can use DateDiff if your dates are going to be the same, otherwise you'll need to strip out the date as above

we can query the msdb in many ways to get the details.

few are

select job.Name, job.job_ID, job.Originating_Server,activity.run_requested_Date,
datediff(minute, activity.run_requested_Date, getdate()) as Elapsed 
from msdb.dbo.sysjobs_view job 
inner join msdb.dbo.sysjobactivity activity on (job.job_id = activity.job_id) 
where run_Requested_date is not null 
and stop_execution_date is null 
and job.name like 'Your Job Prefix%'

I am using ansible 2.5 (2.5.3 exactly), and it seems that the vars file is loaded before the hosts param is executed. So you can set the host in a vars.yml file and just write hosts: {{ host_var }} in your playbook

For example, in my playbook.yml:

---
- hosts: "{{ host_name }}"
  become: yes
  vars_files:
    - vars/project.yml
  tasks:
    ... 

And inside vars/project.yml:

---

# general
host_name: your-fancy-host-name

Assuming you're currently on the branch you want to rename:

git branch -m newname

This is documented in the manual for git-branch, which you can view using

man git-branch

or

git help branch

Specifically, the command is

git branch (-m | -M) [<oldbranch>] <newbranch>

where the parameters are:

   <oldbranch>
       The name of an existing branch to rename.

   <newbranch>
       The new name for an existing branch. The same restrictions as for <branchname> apply.

<oldbranch> is optional, if you want to rename the current branch.

You can use fgets and limit the size of the read string.

char *fgets(char *str, int num, FILE *stream);

You can change the while in your code to:

while (fgets(str, 100, file)) /* printf("%s", str) */;

On the command line, navigate to the root directory of the Java files you wish to make executable.

Use this command:

jar -cvf [name of jar file] [name of directory with Java files]

This will create a directory called META-INF in the jar archive. In this META-INF there is a file called MANIFEST.MF, open this file in a text editor and add the following line:

Main-Class: [fully qualified name of your main class]

then use this command:

java -jar [name of jar file]

and your program will run :)

Either the parameter supplied for ZIP_CODE is larger (in length) than ZIP_CODEs column width or the parameter supplied for CITY is larger (in length) than CITYs column width.

It would be interesting to know the values supplied for the two ? placeholders.

You may catch multiple exceptions in single catch block.

try{
  // somecode throwing multiple exceptions;
} catch (Exception1 | Exception2 | Exception3 exception){
  // handle exception.
} 

The following code, provides a precision way to pause resume a timer.

How it works:

When the timer is resumed after a pause, it generates a correction cycle using a single timeout, that will consider the pause offset (exact time when the timer was paused between cycles). After the correction cycle finishes, it schedules the following cycles with a regular setInteval, and continues normally the cycle execution.

This allows to pause/resume the timer, without losing the sync.

Code :

function Timer(_fn_callback_ , _timer_freq_){_x000D_
    let RESUME_CORRECTION_RATE = 2;_x000D_
_x000D_
    let _timer_statusCode_;_x000D_

You can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:

Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:

Hope this helps.

Did a little research on this, it appears that you are looping from 1 to 2147483647, in increments of 1.

(1, 1, 2147483647): The firs number is the starting number, the next number is the step, and the last number is the end number.

Edited To Add

It appears that the loop runs to completion regardless of any test conditions. I tested

FOR /L %%F IN (1, 1, 5) DO SET %%F=6

And it ran very quickly.

Second Edit

Since this is the only line in the batch file, you might try the EXIT command:

FOR /L %%F IN (1, 1, 2147483647) DO @IF NOT EXIST %%F EXIT

However, this will also close the DOS prompt window.

You should add Hamcrest-library to your Build Path. It contains the needed Matchers.class which has the lessThan() method.

Dependency as below.

<dependency>
  <groupId>org.hamcrest</groupId>
  <artifactId>hamcrest-library</artifactId>
  <version>1.3</version>
  <scope>test</scope>
</dependency>

(if possible) don't use threads, use actors / active objects. Easy to test.

set "PathName=X:\Web Content Mgmt\Completed Filtering\2013_Folder"
set "comd=dir /b /s *.zip"
cd /d "%PathName%"
%comd%

You should use :first-child instead of :first:

Sounds like you're wanting to iterate through them. You can do this using .each().

Example:

$('td:first-child').each(function() {
    console.log($(this).text());
});

Result:

nonono
nonono2
nonono3

Alernatively if you're not wanting to iterate:

$('td:first-child').css('background', '#000');

JSFiddle demo.

A simple example for copy-pasting into Chrome console:

fetch('https://example.com/path', {method:'GET', 
headers: {'Authorization': 'Basic ' + btoa('login:password')}})
.then(response => response.json())
.then(json => console.log(json));

In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.

This is normally more an issue with ToMany than ToOnes. For example,

Select e from Employee e 
join fetch e.phones p 
where p.areaCode = '613'

This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.

Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.

select min(DEPARTMENT.DeptName) as deptname 
from DEPARTMENT
inner join employee on
DEPARTMENT.DeptId = employee.DeptId
where Salary > 1000
group by (EmpId) having count(EmpId) > =2 

I noticed that whenever I would start the form tag inside a div the subsequent div siblings would not be part of the form when I inspect (chrome inspect) henceforth my form would never submit.

<div>
<form>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>

I figured that if I put the form tag outside the DIVs it worked. The form tag should be placed at the start of the parent DIV. Like shown below.

<form>
<div>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>

<!-- map.size here because -->

theoretically the following should work, but i never used it this way.

<%= map.size() // map.size here because %>

I would use expr match instead of =~:

expr match "$date" "[0-9]\{8\}" >/dev/null && echo yes

This is better than the currently accepted answer of using =~ because =~ will also match empty strings, which IMHO it shouldn't. Suppose badvar is not defined, then [[ "1234" =~ "$badvar" ]]; echo $? gives (incorrectly) 0, while expr match "1234" "$badvar" >/dev/null ; echo $? gives correct result 1.

We have to use >/dev/null to hide expr match's output value, which is the number of characters matched or 0 if no match found. Note its output value is different from its exit status. The exit status is 0 if there's a match found, or 1 otherwise.

Generally, the syntax for expr is:

expr match "$string" "$lead"

Or:

expr "$string" : "$lead"

where $lead is a regular expression. Its exit status will be true (0) if lead matches the leading slice of string (Is there a name for this?). For example expr match "abcdefghi" "abc"exits true, but expr match "abcdefghi" "bcd" exits false. (Credit to @Carlo Wood for pointing out this.

z = np.cos(v)
ax.plot_wireframe(x, y, z, color="r")

# draw a point
ax.scatter([0], [0], [0], color="g", s=100)

# draw a vector

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).

I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.

Public Function Rng2Array(inputRange As Range) As Double()

    Dim out() As Double    
    ReDim out(inputRange.Columns.Count - 1)

    Dim cell As Range
    Dim i As Long
    For i = 0 To inputRange.Columns.Count - 1
        out(i) = inputRange(1, i + 1) 'loop over a range "row"
    Next

    Rng2Array = out  
End Function

Its easy to do using Google's Guava library.

e.g. Objects.equal(name, name2) && Objects.equal(age, age2) && ...

I would approach it like this:

sizes = [100, 250] print "How much space should the random song list occupy?" print '\n'.join("{0}. {1}Mb".format(n, s)                 for n, s in enumerate(sizes, 1)) # present choices choice = int(raw_input("Enter choice:")) # throws error if not int size = sizes[0] # safe starting choice if choice in range(2, len(sizes) + 1):     size = sizes[choice - 1] # note index offset from choice print "You  want to create a random song list that is {0}Mb.".format(size) 

You could also loop until you get an acceptable answer and cover yourself in case of error:

choice = 0 while choice not in range(1, len(sizes) + 1): # loop     try: # guard against error         choice = int(raw_input(...))     except ValueError: # couldn't make an int         print "Please enter a number"         choice = 0 size = sizes[choice - 1] # now definitely valid 

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

If I understand the updated question correctly, something like this should work

def function1():
    print "function1 called"

def function2():
    print "function2 called"

def function3():
    print "function3 called"

called_functions = set()
while True:
    n = raw_input("choose a function: 1,2 or 3 ")
    func = {"1": function1,
            "2": function2,
            "3": function3}.get(n)

    if func in called_functions:
        print "That function has already been called"
    else:
        called_functions.add(func)
        func()

I am using the following test to see if strings have been urlencoded:

if(urlencode($str) != str_replace(['%','+'], ['%25','%2B'], $str))

If a string has already been urlencoded, the only characters that will changed by double encoding are % (which starts all encoded character strings) and + (which replaces spaces.) Change them back and you should have the original string.

Let me know if this works for you.

It was solved for me with the Laravel default public/.htaccess file adding an extra line:

The /public/.htaccess file remains as follows:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On
    DirectoryIndex index.php # This line does the trick

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

I think that it depends on your project complexity since angular is pretty much modularized. Your controllers can be mapped and you can just import those JavaScript classes in your index.html page.

But in case your project get bigger. Or you anticipates such scenario, you should integrate angular with requirejs. In this article you can see a demo app for such integration.

I had this issue when upgrading to React 16.12.0.

I had two errors one regarding webpack and the other regarding the store when rendering the DOM.

Webpack Error:

webpack is not recognized as a internal or external command,operable program or batch file

Webpack Solution:

1. Close related VS Solution
2. Delete node_modules folder
3. Deleted package-lock.json
4. npm install
5. npm rebuild
6. Repeated this 2-3 times

Store Error:

Type Store<()> is not assignable to type Store<any, AnyAction>

Store Solution:

Suggestions to update my React version didn't fix this error for me, but irrespective I would recommend doing it.

My code ended up looking like this:

ReactDOM.render(
        <Provider store={store as any}>
            <ConnectedApp />
        </Provider>,
        document.getElementById('app')
    );

As per this solution

to delete a user's session

session.delete(:user_id)

Try something like:

preg_replace('/\d{3}/', '$0-', str_replace('.', null, trim($number)), 2);

this would take a $number of 8881112222 and convert to 888-111-2222. Hope this helps.

my mistake was making the target name "filename.c:" instead of just "filename:"

Character varying is different than text. Try running

ALTER TABLE product_product ALTER COLUMN code TYPE text;

That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)

try this method

<script type="text/javascript">

    function set(value) {
        return value;
    }

    alert(set(@Html.Raw(Json.Encode(Model.Message)))); // Message set from controller
    alert(set(@Html.Raw(Json.Encode(ViewBag.UrMessage))));

</script>

Thanks

You need to dig a bit deeper into the api to do this:

From the docs

To whitelist an entire hash of parameters, the permit! method can be used

params.require(:log_entry).permit!

Nested attributes are in the form of a hash. In my app, I have a Question.rb model accept nested attributes for an Answer.rb model (where the user creates answer choices for a question he creates). In the questions_controller, I do this

  def question_params

      params.require(:question).permit!

  end

Everything in the question hash is permitted, including the nested answer attributes. This also works if the nested attributes are in the form of an array.

Having said that, I wonder if there's a security concern with this approach because it basically permits anything that's inside the hash without specifying exactly what it is, which seems contrary to the purpose of strong parameters.

Try this:

re.compile(r"^(.+)\n((?:\n.+)+)", re.MULTILINE)

I think your biggest problem is that you're expecting the ^ and $ anchors to match linefeeds, but they don't. In multiline mode, ^ matches the position immediately following a newline and $ matches the position immediately preceding a newline.

Be aware, too, that a newline can consist of a linefeed (\n), a carriage-return (\r), or a carriage-return+linefeed (\r\n). If you aren't certain that your target text uses only linefeeds, you should use this more inclusive version of the regex:

re.compile(r"^(.+)(?:\n|\r\n?)((?:(?:\n|\r\n?).+)+)", re.MULTILINE)

BTW, you don't want to use the DOTALL modifier here; you're relying on the fact that the dot matches everything except newlines.

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')

In pre-2.5 Python, you can replace datetime.strptime with time.strptime, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))

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

That would just be:

 Console.WriteLine(Variables.name);

and it needs to be public also:

public class Variables
{
   public static string name = "";
}

Simplifying a bit, you can imagine map() doing something like this:

def mymap(func, lst):
    result = []
    for e in lst:
        result.append(func(e))
    return result

As you can see, it takes a function and a list, and returns a new list with the result of applying the function to each of the elements in the input list. I said "simplifying a bit" because in reality map() can process more than one iterable:

If additional iterable arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended with None items.

For the second part in the question: What role does this play in making a Cartesian product? well, map() could be used for generating the cartesian product of a list like this:

lst = [1, 2, 3, 4, 5]

from operator import add
reduce(add, map(lambda i: map(lambda j: (i, j), lst), lst))

... But to tell the truth, using product() is a much simpler and natural way to solve the problem:

from itertools import product
list(product(lst, lst))

Either way, the result is the cartesian product of lst as defined above:

[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5),
 (2, 1), (2, 2), (2, 3), (2, 4), (2, 5),
 (3, 1), (3, 2), (3, 3), (3, 4), (3, 5),
 (4, 1), (4, 2), (4, 3), (4, 4), (4, 5),
 (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]

Similarly to making your PC a wireless access point, but can be much easier, is using reverse tethering. If you happen to have an HTC phone they have a nice reverse-tethering option called "Internet pass-through", under the network/mobile network sharing settings. It routes all your traffic through your PC and you can just run Wireshark there.

I have a different perspective to answering this. This sort of answers "what else can I do to avoid it?"

When working across different layers, for example in an MVC application, a controller needs services to call business operations. In such scenarios Dependency Injection Container can be used to initialize the services to avoid the NullReferenceException. So that means you don't need to worry about checking for null and just call the services from the controller as though they will always to available (and initialized) as either a singleton or a prototype.

public class MyController
{
    private ServiceA serviceA;
    private ServiceB serviceB;

    public MyController(ServiceA serviceA, ServiceB serviceB)
    {
        this.serviceA = serviceA;
        this.serviceB = serviceB;
    }

    public void MyMethod()
    {
        // We don't need to check null because the dependency injection container 
        // injects it, provided you took care of bootstrapping it.
        var someObject = serviceA.DoThis();
    }
}

Arrays Vs. Lists is a classic maintainability vs. performance problem. The rule of thumb that nearly all developers follow is that you should shoot for both, but when they come in to conflict, choose maintainability over performance. The exception to that rule is when performance has already proven to be an issue. If you carry this principle in to Arrays Vs. Lists, then what you get is this:

Use strongly typed lists until you hit performance problems. If you hit a performance problem, make a decision as to whether dropping out to arrays will benefit your solution with performance more than it will be a detriment to your solution in terms of maintenance.

The following definition might be more efficient than the first solution proposed

def new_list_from_intervals(original_list, *intervals):
    n = sum(j - i for i, j in intervals)
    new_list = [None] * n
    index = 0
    for i, j in intervals :
        for k in range(i, j) :
            new_list[index] = original_list[k]
            index += 1

    return new_list

then you can use it like below

new_list = new_list_from_intervals(original_list, (0,2), (4,5), (6, len(original_list)))

I was having the same problem using the python email functions. Below is the code I was trying to retrieve email subject into a variable. This works fine for most emails and the variable populates. If you receive an email from Yahoo or the like and the sender did no fill out the subject line Yahoo does not create a subject line in the email and you get a NoneType returned from the function. Martineau provided a correct answer as well as Soviut. IMO Soviut's answer is more concise from a programming stand point; not necessarily from a Python one. Here is some code to show the technique:

import sys, email, email.Utils 

afile = open(sys.argv[1], 'r')    
m = email.message_from_file(afile)    
subject = m["subject"]

# Soviut's Concise test for unset variable.

if subject is None:    
     subject = "[NO SUBJECT]"

# Alternative way to test for No Subject created in email (Thanks for NoneThing Yahoo!)

try:    
    if len(subject) == 0:    
        subject = "[NO SUBJECT]"

except TypeError:    
    subject = "[NO SUBJECT]"

print subject

afile.close()

From the manual:

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment.

So you can do (from bash):

FOOBAR=1 make

resulting in a variable FOOBAR in your Makefile.

I think everything that you need is array_key_exists:

if (!array_key_exists('id', $access_data['Privilege'])) {
                $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
                return $this->redirect(array('controller' => 'Dashboard', 'action' => 'index'));
            }

Restarting my PC made it worked.

We can accomplish the task in two simple way one is using Json.NET dll and another is by using StringBuilder class.

            if (i == ds.Tables[0].Rows.Count - 1)
            {
                JsonString.Append("}");
            }
            else
            {
                JsonString.Append("},");
            }

HTML5

Keeping in mind that ID must be unique, ie. there must not be multiple elements in a document that have the same id value.

The rules about ID content in HTML5 are (apart from being unique):

This attribute's value must not contain white spaces. [...] 
Though this restriction has been lifted in HTML 5, 
an ID should start with a letter for compatibility.

This is the W3 spec about ID (från MDN):

Any string, with the following restrictions:
must be at least one character long
must not contain any space characters
Previous versions of HTML placed greater restrictions on the content of ID values 
(for example, they did not permit ID values to begin with a number).

More info:

• W3 - global attributes (id)
• MDN atribute (id)

From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)

The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.

In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.

Go to the Sql tab run one of the below query:

delete from tableName;

Delete: will delete all rows from your table. Next insert will take next auto increment id.

or

truncate tableName;

Truncate: will also delete the rows from your table but it will start from new row with 1.

I know this doesn't use flexbox, but for the simple use-case of three items (one at left, one at center, one at right), this can be accomplished easily using display: grid on the parent, grid-area: 1/1/1/1; on the children, and justify-self for positioning of those children.

<div style="border: 1px solid red; display: grid; width: 100px; height: 25px;">_x000D_
  <div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: left;"></div>_x000D_
  <div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: center;"></div>_x000D_
  <div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: right;"></div>_x000D_
</div>

Use this instead:

<?
session_start();
session_unset();
session_destroy();

header("location:home.php");
exit();
?>

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}

    function (array_of_Tabs) {  //Tab tab
        arrayLength = array_of_Tabs.length;
        //alert(arrayLength);
        for (var i = 0; i < arrayLength; i++) {
            myArray.push(array_of_Tabs[i].url);
        }
        obj = JSON.parse(JSON.stringify(myArray));
    });
}, false);

This feature will never be part of Sass. One major reason is import order. In CSS, the files imported last can override the styles stated before. If you import a directory, how can you determine import order? There's no way that doesn't introduce some new level of complexity. By keeping a list of imports (as you did in your example), you're being explicit with import order. This is essential if you want to be able to confidently override styles that are defined in another file or write mixins in one file and use them in another.

There is another solution if you want to develop in C/C++. http://www.DragonFireSDK.com will allow you to build iPhone applications in Visual Studio on Windows. It's worth a look-see for sure.

If you are not limiting yourself to the standard library, I like psutil for this.

For instance to find all "python" processes:

>>> import psutil
>>> [p.info for p in psutil.process_iter(attrs=['pid', 'name']) if 'python' in p.info['name']]
[{'name': 'python3', 'pid': 21947},
 {'name': 'python', 'pid': 23835}]

From my experience, won't recommend my below answer for any public facing Web applications.

If you need it for your inhouse tools or for Testing, I would recommend to share it on your own machine.

-Right click on the root path you need to access
-Choose Properties
-Click on Share button and add your chosen users who can access it

This will then create a shared directory like \\{PCName}\{YourSharedRootDirectory} This could be definitely much less than your full path I hope, for me I could reduce to 30 characters from about 290 characters. :)

use checked : true, false property of the checkbox.

jQuery:

if($('input[type=checkbox]').is(':checked')) {
    $(this).prop('checked',true);
} else {
    $(this).prop('checked',false);
}

This is called Fixed Header Scrolling. There are a number of documented approaches:

http://www.imaputz.com/cssStuff/bigFourVersion.html

You won't effectively pull this off without JavaScript ... especially if you want cross browser support.

There are a number of gotchyas with any approach you take, especially concerning cross browser/version support.

Edit:

Even if it's not the header you want to fix, but the first row of data, the concept is still the same. I wasn't 100% which you were referring to.

Additional thought I was tasked by my company to research a solution for this that could function in IE7+, Firefox, and Chrome.

After many moons of searching, trying, and frustration it really boiled down to a fundamental problem. For the most part, in order to gain the fixed header, you need to implement fixed height/width columns because most solutions involve using two separate tables, one for the header which will float and stay in place over the second table that contains the data.

//float this one right over second table
<table>
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
</table>

<table>
//Data
</table>

An alternative approach some try is utilize the tbody and thead tags but that is flawed too because IE will not allow you put a scrollbar on the tbody which means you can't limit its height (so stupid IMO).

<table>
  <thead style="do some stuff to fix its position">
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  </thead>
  <tbody style="No scrolling allowed here!">
     Data here
  </tbody>
</table>

This approach has many issues such as ensures EXACT pixel widths because tables are so cute in that different browsers will allocate pixels differently based on calculations and you simply CANNOT (AFAIK) guarantee that the distribution will be perfect in all cases. It becomes glaringly obvious if you have borders within your table.

I took a different approach and said screw tables since you can't make this guarantee. I used divs to mimic tables. This also has issues of positioning the rows and columns (mainly because floating has issues, using in-line block won't work for IE7, so it really left me with using absolute positioning to put them in their proper places).

There is someone out there that made the Slick Grid which has a very similar approach to mine and you can use and a good (albeit complex) example for achieving this.

https://github.com/6pac/SlickGrid/wiki

doThrow : Basically used when you want to throw an exception when a method is being called within a mock object.

public void validateEntity(final Object object){}
Mockito.doThrow(IllegalArgumentException.class)
.when(validationService).validateEntity(Matchers.any(AnyObjectClass.class));

doReturn : Used when you want to send back a return value when a method is executed.

public Socket getCosmosSocket() throws IOException {}
Mockito.doReturn(cosmosSocket).when(cosmosServiceImpl).getCosmosSocket();

doAnswer: Sometimes you need to do some actions with the arguments that are passed to the method, for example, add some values, make some calculations or even modify them doAnswer gives you the Answer interface that being executed in the moment that method is called, this interface allows you to interact with the parameters via the InvocationOnMock argument. Also, the return value of answer method will be the return value of the mocked method.

public ReturnValueObject quickChange(Object1 object);
Mockito.doAnswer(new Answer<ReturnValueObject>() {

        @Override
        public ReturnValueObject answer(final InvocationOnMock invocation) throws Throwable {

            final Object1 originalArgument = (invocation.getArguments())[0];
            final ReturnValueObject returnedValue = new ReturnValueObject();
            returnedValue.setCost(new Cost());

            return returnedValue ;
        }
}).when(priceChangeRequestService).quickCharge(Matchers.any(Object1.class));

doNothing: Is the easiest of the list, basically it tells Mockito to do nothing when a method in a mock object is called. Sometimes used in void return methods or method that does not have side effects, or are not related to the unit testing you are doing.

public void updateRequestActionAndApproval(final List<Object1> cmItems);

Mockito.doNothing().when(pagLogService).updateRequestActionAndApproval(
                Matchers.any(Object1.class));

Using docker-compose, you can inherit env variables in docker-compose.yml and subsequently any Dockerfile(s) called by docker-compose to build images. This is useful when the Dockerfile RUN command should execute commands specific to the environment.

(your shell has RAILS_ENV=development already existing in the environment)

docker-compose.yml:

version: '3.1'
services:
  my-service: 
    build:
      #$RAILS_ENV is referencing the shell environment RAILS_ENV variable
      #and passing it to the Dockerfile ARG RAILS_ENV
      #the syntax below ensures that the RAILS_ENV arg will default to 
      #production if empty.
      #note that is dockerfile: is not specified it assumes file name: Dockerfile
      context: .
      args:
        - RAILS_ENV=${RAILS_ENV:-production}
    environment: 
      - RAILS_ENV=${RAILS_ENV:-production}

Dockerfile:

FROM ruby:2.3.4

#give ARG RAILS_ENV a default value = production
ARG RAILS_ENV=production

#assign the $RAILS_ENV arg to the RAILS_ENV ENV so that it can be accessed
#by the subsequent RUN call within the container
ENV RAILS_ENV $RAILS_ENV

#the subsequent RUN call accesses the RAILS_ENV ENV variable within the container
RUN if [ "$RAILS_ENV" = "production" ] ; then echo "production env"; else echo "non-production env: $RAILS_ENV"; fi

This way, I don't need to specify environment variables in files or docker-compose build/up commands:

docker-compose build
docker-compose up

I had this same problem, because my line of code was:

txtTotalInvoice.setText(var1.divide(var2).doubleValue() + "");

I change to this, reading previous Answer, because I was not writing decimal precision:

txtTotalInvoice.setText(var1.divide(var2,4, RoundingMode.HALF_UP).doubleValue() + "");

4 is Decimal Precison

AND RoundingMode are Enum constants, you could choose any of this UP, DOWN, CEILING, FLOOR, HALF_DOWN, HALF_EVEN, HALF_UP

In this Case HALF_UP, will have this result:

2.4 = 2   
2.5 = 3   
2.7 = 3

You can check the RoundingMode information here: http://www.javabeat.net/precise-rounding-of-decimals-using-rounding-mode-enumeration/

As Wagner Francisco said, (in JADE)

input(type="text", ng-model="someModel", placeholder="{{someScopeVariable}}")`

And in your controller :

$scope.someScopeVariable = 'somevalue'

I would like to make a addon for tiago's answer:

Suppose you're hiding element using ng-show and adding a required attribute on the same:

<div ng-show="false">
    <input required name="something" ng-model="name"/>
</div>

will throw an error something like :

An invalid form control with name='' is not focusable

This is because you just cannot impose required validation on hidden elements. Using ng-required makes it easier to conditionally apply required validation which is just awesome!!

I find many answers up to date and properly answered but will add something new to stack of answers.

In python there are infinite ways to do this, here are some instances
Normal way

>>> l= [1,2,"stackoverflow","python"]
>>> l
[1, 2, 'stackoverflow', 'python']
>>> tup = tuple(l)
>>> type(tup)
<type 'tuple'>
>>> tup
(1, 2, 'stackoverflow', 'python')

smart way

>>>tuple(item for item in l)
(1, 2, 'stackoverflow', 'python')

Remember tuple is immutable ,used for storing something valuable. For example password,key or hashes are stored in tuples or dictionaries. If knife is needed why to use sword to cut apples. Use it wisely, it will also make your program efficient.

I'm not sure exactly what your problem is, because I cannot get your code to work as written. Two things seem evident:

1. It appears you are relying on VBA to determine variable types and modify accordingly. This can get confusing if you are not careful, because VBA may assign a variable type you did not intend. In your code, a type of Range should be assigned to myRange. Since a Range type is an object in VBA it needs to be Set, like this: Set myRange = Range("A:A")
2. Your use of the worksheet function CountA() should be called with .WorksheetFunction

If you are not doing it already, consider using the Option Explicit option at the top of your module, and typing your variables with Dim statements, as I have done below.

The following code works for me in 2010. Hopefully it works for you too:

Dim myRange As Range
Dim NumRows As Integer

Set myRange = Range("A:A")
NumRows = Application.WorksheetFunction.CountA(myRange)

Good Luck.

Press Ctrl-a then : and then type

scrollback 10000

to get a 10000 line buffer, for example.

You can also set the default number of scrollback lines by adding

defscrollback 10000

to your ~/.screenrc file.

To scroll (if your terminal doesn't allow you to by default), press Ctrl-a ESC and then scroll (with the usual Ctrl-f for next page or Ctrl-a for previous page, or just with your mouse wheel / two-fingers). To exit the scrolling mode, just press ESC.

Another tip: Ctrl-a i shows your current buffer setting.

The following code solved the problem (with jQuery).

var vhHeight = $("body").height();
var chromeNavbarHeight = vhHeight - window.innerHeight;
$('body').css({ height: window.innerHeight, marginTop: chromeNavbarHeight });

And the other elements use % as a unit to replace vh.

For portability, you really should do something like this:

public static final String NEW_LINE = System.getProperty("line.separator")
.
.
.
word.contains(NEW_LINE);

unless you're absolutely certain that "\n" is what you want.

To add okhttp as a dependency do as follows

• right click on the app on android studio open "module settings"
• "dependencies"-> "add library dependency" -> "com.squareup.okhttp3:okhttp:3.10.0" -> add -> ok..

now you have okhttp as a dependency

Now design a interface as below so we can have the callback to our activity once the network response received.

public interface NetworkCallback {

    public void getResponse(String res);
}

I create a class named NetworkTask so i can use this class to handle all the network requests

    public class NetworkTask extends AsyncTask<String , String, String>{

    public NetworkCallback instance;
    public String url ;
    public String json;
    public int task ;
    OkHttpClient client = new OkHttpClient();
    public static final MediaType JSON
            = MediaType.parse("application/json; charset=utf-8");

    public NetworkTask(){

    }

    public NetworkTask(NetworkCallback ins, String url, String json, int task){
        this.instance = ins;
        this.url = url;
        this.json = json;
        this.task = task;
    }


    public String doGetRequest() throws IOException {
        Request request = new Request.Builder()
                .url(url)
                .build();

        Response response = client.newCall(request).execute();
        return response.body().string();
    }

    public String doPostRequest() throws IOException {
        RequestBody body = RequestBody.create(JSON, json);
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Response response = client.newCall(request).execute();
        return response.body().string();
    }

    @Override
    protected String doInBackground(String[] params) {
        try {
            String response = "";
            switch(task){
                case 1 :
                    response = doGetRequest();
                    break;
                case 2:
                    response = doPostRequest();
                    break;

            }
            return response;
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        instance.getResponse(s);
    }
}

now let me show how to get the callback to an activity

    public class MainActivity extends AppCompatActivity implements NetworkCallback{
    String postUrl = "http://your-post-url-goes-here";
    String getUrl = "http://your-get-url-goes-here";
    Button doGetRq;
    Button doPostRq;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = findViewById(R.id.button);

        doGetRq = findViewById(R.id.button2);
    doPostRq = findViewById(R.id.button1);

        doPostRq.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                MainActivity.this.sendPostRq();
            }
        });

        doGetRq.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                MainActivity.this.sendGetRq();
            }
        });
    }

    public void sendPostRq(){
        JSONObject jo = new JSONObject();
        try {
            jo.put("email", "yourmail");
            jo.put("password","password");

        } catch (JSONException e) {
            e.printStackTrace();
        }
    // 2 because post rq is for the case 2
        NetworkTask t = new NetworkTask(this, postUrl,  jo.toString(), 2);
        t.execute(postUrl);
    }

    public void sendGetRq(){

    // 1 because get rq is for the case 1
        NetworkTask t = new NetworkTask(this, getUrl,  jo.toString(), 1);
        t.execute(getUrl);
    }

    @Override
    public void getResponse(String res) {
    // here is the response from NetworkTask class
    System.out.println(res)
    }
}

If project is a ASP.net MVC project it would be about routing. In my case I changed default routing values:

routes.MapRoute(
           "Default",                                              
           "{controller}/{action}/{id}",                           
           new { controller = "Home", action = "Index", id = "" }  
       );

I changed my code accidentally to:

routes.MapRoute(
               "Default",                                              
               "{controller}/{action}/{JobID}",                           
               new { controller = "Home", action = "Index", id = "" }  
           );

Thats I only changed "id" to "JobId" and default route can not be find.

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.

Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.

User.delete_all(condition: 'value') will allow you to delete records without a primary key

Note: from @hammady's comment, user.destroy won't work if User model has no primary key.

Note 2: From @pavel-chuchuva's comment, destroy_all with conditions and delete_all with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

Yes, it can do that, but strictly speaking that will assign the default value if the retrieved value is falsey, as opposed to truly undefined. It would therefore not only match undefined but also null, false, 0, NaN, "" (but not "0").

If you want to set to default only if the variable is strictly undefined then the safest way is to write:

var x = (typeof x === 'undefined') ? your_default_value : x;

On newer browsers it's actually safe to write:

var x = (x === undefined) ? your_default_value : x;

but be aware that it is possible to subvert this on older browsers where it was permitted to declare a variable named undefined that has a defined value, causing the test to fail.

IF they Give Path Directory Error!

In MAC Then Go to Folder Get Info and Open Storage and Permission change to privileges Read To Write

If you need to go a step further than @alon's detailed steps and also create a self signed ca:

https.createServer({
  key: fs.readFileSync(NODE_SSL_KEY),
  cert: fs.readFileSync(NODE_SSL_CERT),
  ca: fs.readFileSync(NODE_SSL_CA),
}, app).listen(PORT, () => {});

package.json

"setup:https": "openssl genrsa -out src/server/ssl/localhost.key 2048

distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no

Look at my code, but be aware. I use async/await, because latest Chrome beta can read any es6 code, which gets by TypeScript with compilation. So, you must replace asyns/await by .then().

Input change handler:

/**
 * @param fileInput
 */
public psdTemplateSelectionHandler (fileInput: any){
    let FileList: FileList = fileInput.target.files;

    for (let i = 0, length = FileList.length; i < length; i++) {
        this.psdTemplates.push(FileList.item(i));
    }

    this.progressBarVisibility = true;
}

Submit handler:

public async psdTemplateUploadHandler (): Promise<any> {
    let result: any;

    if (!this.psdTemplates.length) {
        return;
    }

    this.isSubmitted = true;

    this.fileUploadService.getObserver()
        .subscribe(progress => {
            this.uploadProgress = progress;
        });

    try {
        result = await this.fileUploadService.upload(this.uploadRoute, this.psdTemplates);
    } catch (error) {
        document.write(error)
    }

    if (!result['images']) {
        return;
    }

    this.saveUploadedTemplatesData(result['images']);
    this.redirectService.redirect(this.redirectRoute);
}

FileUploadService. That service also stored uploading progress in progress$ property, and in other places, you can subscribe on it and get new value every 500ms.

First of all, create a Github account and project in Github. Go to the root folder and follow steps.

The most important thing we forgot here is ignoring the file. Every time we run Gradle or build it creates new files that are changeable from build to build and pc to pc. We do not want all the files from Android Studio to be added to Git. Files like generated code, binary files (executables) should not be added to Git (version control). So please use .gitignore file while uploading projects to Github. It also reduces the size of the project uploaded to the server.

1. Go to root folder.
2. git init

3. Create .gitignore txt file in root folder. Place these content in the file. (this step not required if the file is auto-generated)

   *.iml .gradle /local.properties /.idea/workspace.xml /.idea/libraries .idea .DS_Store /build /captures .externalNativeBuild

4. git add .
5. git remote add origin https://github.com/username/project.git
6. git commit - m "My First Commit"
7. git push -u origin master

Note : As per suggestion from different developers, they always suggest to use git from the command line. It is up to you.

Starting from Visual Studio 2017 (15.9.4) there is an option:

Tools->Options->Debugging->Automatically close the console

The corresponding fragment from the Visual Studio documentation:

Automatically close the console when debugging stops:

Tells Visual Studio to close the console at the end of a debugging session.

To get current user info:

jQuery.ajax({
    url: _spPageContextInfo.webServerRelativeUrl + "/_api/web/currentuser",
    type: "GET",
    headers: { "Accept": "application/json;odata=verbose" }
}).done(function( data ){
    console.log( data );
    console.log( data.d.Title );
}).fail(function(){
    console.log( failed );
});

Better is to Make a global Constants class to save key or variables to fetch or save data.

To save data call this method to save data from every where.

public static void saveData(Context con, String variable, String data)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    prefs.edit().putString(variable, data).commit();
}

Use it to get data.

public static String getData(Context con, String variable, String defaultValue)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    String data = prefs.getString(variable, defaultValue);
    return data;
}

and a method something like this will do the trick

public static User getUserInfo(Context con)
{
    String id =  getData(con, Constants.USER_ID, null);
    String name =  getData(con, Constants.USER_NAME, null);
    if(id != null && name != null)
    {
            User user = new User(); //Hope you will have a user Object.
            user.setId(id);
            user.setName(name);
            //Here set other credentials.
            return user;
    }
    else
    return null;
}

You could pass an object as attribute and read it into the directive like this:

<div my-directive="{id:123,name:'teo',salary:1000,color:red}"></div>

app.directive('myDirective', function () {
    return {            
        link: function (scope, element, attrs) {
           //convert the attributes to object and get its properties
           var attributes = scope.$eval(attrs.myDirective);       
           console.log('id:'+attributes.id);
           console.log('id:'+attributes.name);
        }
    };
});

Try to change Bundle Identifier: Project -> Targets/[Your project] -> General -> Bundle Identifier

If app was published at AppStore XCode doesn't allow create the application with the same bundle identifier.

Little addition, to run an interpreter from the same folder, still using #!hashbang in scripts.

As example a php7.2 executable copied from /usr/bin is in a folder along a hello script.

#!./php7.2
<?php

echo "Hello!"; 

To run it:

./hello

Which behave just as equal as:

./php7.2 hello

The proper solutions with good documentation can be the tools linuxdeploy and/or appimage, this is using this method under the hood.

You may try AngryHosts, which provided a way to support wildcard and regular expression. Actually, it's a hosts file enhancement and management software.

From LDAP, there is not a query method to determine an empty string.

The best practice would be to scrub your data inputs to LDAP as an empty or null value in LDAP is no value at all.

To determine this you would need to query for all with a value (manager=*) and then use code to determine the ones that were a "space" or null value.

And as Terry said, storing an empty or null value in an attribute of DN syntax is wrong.

Some LDAP server implementations will not permit entering a DN where the DN entry does not exist.

Perhaps, you could, if your DN's are consistent, use something like:

(&(!(manager=cn*))(manager=*))

This should return any value of manager where there was a value for manager and it did not start with "cn".

However, some LDAP implementations will not allow sub-string searches on DN syntax attributes.

You can right-click on your project then Maven > Update Project..., then select Force Update of Snapshots/Releases checkbox then click OK.

I did it with an ajax post and then returned using a data url:

$(document).ready(function () {
    var exportClick = function () {
        $.ajax({
           url: "/api/test.php",
           type: "POST",
           dataType: "text",
           data: {
              action: "getCSV",
              filter: "name = 'smith'",
           },
           success: function(data) {
              var w = window.open('data:text/csv;charset=utf-8,' + encodeURIComponent(data));
              w.focus();
           },
           error: function () {
              alert('Problem getting data');
           },
        });
    }
});

Common sense works here: os is a module, and os.path is a module, too. So just import the module you want to use:

• If you want to use functionalities in the os module, then import os.

• If you want to use functionalities in the os.path module, then import os.path.

• If you want to use functionalities in both modules, then import both modules:

  import os
  import os.path
  

For reference:

• Lib/idlelib/rpc.py uses os and imports os.

• Lib/idlelib/idle.py uses os.path and imports os.path.

• Lib/ensurepip/init.py uses both and imports both.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); } 

Hapy New Year :)

If you have a one to many relationship in your query, duplicate rows may occurs on one side.

Suppose the following

TABLE TEAM
ID       TEAM_NAME
0        BULLS
1        LAKERS


TABLE PLAYER
ID       TEAM_ID     PLAYER_NAME
0        0           JORDAN
1        0           PIPPEN

And you execute a query like

SELECT 
    TEAM.TEAM_NAME, 
    PLAYER.PLAYER_NAME 
FROM TEAM
INNER JOIN PLAYER

You will get

TEAM_NAME   PLAYER_NAME
BULLS       JORDAN
BULLS       PIPPEN

So you will have duplicate TEAM NAME. Even using DISTINCT clause, your result set will contain duplicate TEAM NAME

So if you do not want duplicate TEAM_NAME in your query, do the following

SELECT ID, TEAM_NAME FROM TEAM

And for each team ID encountered executes

SELECT PLAYER_NAME FROM PLAYER WHERE TEAM_ID = <PUT_TEAM_ID_RIGHT_HERE>

So this way you will not get duplicates references on one side

regards,

From https://git-scm.com/docs/git-reset#Documentation/git-reset.txt-Undoamergeorpullinsideadirtyworkingtree

Undo a merge or pull inside a dirty working tree

$ git pull           (1)
Auto-merging nitfol
Merge made by recursive.
 nitfol               |   20 +++++----
 ...
$ git reset --merge ORIG_HEAD      (2)

Even if you may have local modifications in your working tree, you can safely say git pull when you know that the change in the other branch does not overlap with them.

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running git reset --hard ORIG_HEAD will let you go back to where you were, but it will discard your local changes, which you do not want. git reset --merge keeps your local changes.

Screen.lockOrientation() solves this problem, though support is less than universal at the time (April 2017):

https://www.w3.org/TR/screen-orientation/

https://developer.mozilla.org/en-US/docs/Web/API/Screen.lockOrientation

EDIT: http://jsfiddle.net/nCFGL/223/ My Example.

You should be able to like follows:

var pieData = [{
    value: 30,
    color: "#F38630",
    label: 'Sleep',
    labelColor: 'white',
    labelFontSize: '16'
  },
  ...
];

I had many issues involving C# and SqlServer. I ended up doing the following:

1. On SQL Server I use the DateTime column type
2. On c# I use the .ToString("yyyy-MM-dd HH:mm:ss") method

Also make sure that all your machines run on the same timezone.

Regarding the different result sets you get, your first example is "July First" while the second is "4th of July" ...

Also, the second example can be also interpreted as "April 7th", it depends on your server localization configuration (my solution doesn't suffer from this issue).

EDIT: hh was replaced with HH, as it doesn't seem to capture the correct hour on systems with AM/PM as opposed to systems with 24h clock. See the comments below.

No, there is no built-in support for number formatting, but googling will turn up loads of code snippets that will do this for you.

EDIT: I missed the last sentence of your post. Try http://code.google.com/p/jquery-utils/wiki/StringFormat for a jQuery solution.

Here is a solution to prevent session shearing between browser tabs for a java application. This will work for IE (JSP/Servlet)

1. In your first JSP page, onload event call a servlet (ajex call) to setup a "window.title" and event tracker in the session(just a integer variable to be set as 0 for first time)
2. Make sure none of the other pages set a window.title
3. All pages (including the first page) add a java script to check the window title once the page load is complete. if the title is not found then close the current page/tab(make sure to undo the "window.unload" function when this occurs)
4. Set page window.onunload java script event(for all pages) to capture the page refresh event, if a page has been refreshed call the servlet to reset the event tracker.

1)first page JS

BODY onload="javascript:initPageLoad()"

function initPageLoad() {
    var xmlhttp;

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {                           var serverResponse = xmlhttp.responseText;
            top.document.title=serverResponse;
        }
    };
                xmlhttp.open("GET", 'data.do', true);
    xmlhttp.send();

}

2)common JS for all pages

window.onunload = function() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {             
            var serverResponse = xmlhttp.responseText;              
        }
    };

    xmlhttp.open("GET", 'data.do?reset=true', true);
    xmlhttp.send();
}

var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
    init();
    clearInterval(readyStateCheckInterval);
}}, 10);
function init(){ 
  if(document.title==""){   
  window.onunload=function() {};
  window.open('', '_self', ''); window.close();
  }
 }

3)web.xml - servlet mapping

<servlet-mapping>
<servlet-name>myAction</servlet-name>
<url-pattern>/data.do</url-pattern>     
</servlet-mapping>  
<servlet>
<servlet-name>myAction</servlet-name>
<servlet-class>xx.xxx.MyAction</servlet-class>
</servlet>

4)servlet code

public class MyAction extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException {
    Integer sessionCount = (Integer) request.getSession().getAttribute(
            "sessionCount");
    PrintWriter out = response.getWriter();
    Boolean reset = Boolean.valueOf(request.getParameter("reset"));
    if (reset)
        sessionCount = new Integer(0);
    else {
        if (sessionCount == null || sessionCount == 0) {
            out.println("hello Title");
            sessionCount = new Integer(0);
        }
                          sessionCount++;
    }
    request.getSession().setAttribute("sessionCount", sessionCount);
    // Set standard HTTP/1.1 no-cache headers.
    response.setHeader("Cache-Control", "private, no-store, no-cache, must-                      revalidate");
    // Set standard HTTP/1.0 no-cache header.
    response.setHeader("Pragma", "no-cache");
} 
  }
