you should install a x server such as XMing. and keep the x server is running. config your putty like this :Connection-Data-SSH-X11-Enable X11 forwarding should be checked. and X display location : localhost:0

You can use the onsubmit function.

If you return false the form won't get submitted. Read up about it here.

$('#myform').submit(function() {
  // your code here
});

There's an article on Code Project about using GDI+ for .NET to do photo resizing using, say, Bicubic interpolation.

There was also another article about this topic on another blog (MS employee, I think), but I can't find the link anywhere. :( Perhaps someone else can find it?

import syslog
syslog.openlog(ident="LOG_IDENTIFIER",logoption=syslog.LOG_PID, facility=syslog.LOG_LOCAL0)
syslog.syslog('Log processing initiated...')

the above script will log to LOCAL0 facility with our custom "LOG_IDENTIFIER"... you can use LOCAL[0-7] for local purpose.

You want DateTime.DaysInMonth:

int days = DateTime.DaysInMonth(year, month);

Obviously it varies by year, as sometimes February has 28 days and sometimes 29. You could always pick a particular year (leap or not) if you want to "fix" it to one value or other.

    ##If i want to wait for some response from server or any action we use setTimeOut.

    functionOne =function(){
    console.info("First");

    setTimeout(()=>{
    console.info("After timeOut 1");
    },5000);
    console.info("only setTimeOut() inside code waiting..");
    }

    functionTwo =function(){
    console.info("second");
    }
    functionOne();
    functionTwo();

## So here console.info("After timeOut 1"); will be executed after time elapsed.
Output:
******************************************************************************* 
First
only setTimeOut() inside code waiting..
second
undefined
After timeOut 1  // executed after time elapsed.

For me the scrollTop way did not work, but I found other:

element.style.display = 'none';
setTimeout(function() { element.style.display = 'block' }, 100);

Did not check the minimum time for reliable css rendering though, 100ms might be overkill.

localbroadcastmanager is deprecated, use implementations of the observable pattern instead.

androidx.localbroadcastmanager is being deprecated in version 1.1.0

Reason

LocalBroadcastManager is an application-wide event bus and embraces layer violations in your app; any component may listen to events from any other component. It inherits unnecessary use-case limitations of system BroadcastManager; developers have to use Intent even though objects live in only one process and never leave it. For this same reason, it doesn’t follow feature-wise BroadcastManager .

These add up to a confusing developer experience.

Replacement

You can replace usage of LocalBroadcastManager with other implementations of the observable pattern. Depending on your use case, suitable options may be LiveData or reactive streams.

Advantage of LiveData

You can extend a LiveData object using the singleton pattern to wrap system services so that they can be shared in your app. The LiveData object connects to the system service once, and then any observer that needs the resource can just watch the LiveData object.

 public class MyFragment extends Fragment {
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        LiveData<BigDecimal> myPriceListener = ...;
        myPriceListener.observe(this, price -> {
            // Update the UI.
        });
    }
}

The observe() method passes the fragment, which is an instance of LifecycleOwner, as the first argument. Doing so denotes that this observer is bound to the Lifecycle object associated with the owner, meaning:

• If the Lifecycle object is not in an active state, then the observer isn't called even if the value changes.

• After the Lifecycle object is destroyed, the observer is automatically removed

The fact that LiveData objects are lifecycle-aware means that you can share them between multiple activities, fragments, and services.

On my Ubuntu VM, with 1048 MB total RAM, java -XX:+PrintFlagsFinal -version | grep HeapSize printed : uintx MaxHeapSize := 266338304, which is approx 266MB and is 1/4th of my total RAM.

Add programatically noborder class to specific row to hide it

       <th>heading2</th>
    </tr>


    <tr>
       <td>content1</td>
       <td>content2</td>
    </tr>
    /*no border for this row */
    <tr class="noborder">
       <td>content1</td>
       <td>content2</td>
    </tr>

</table>

reverse the string and then, in a second pass, reverse each word...

in c#, completely in-place without additional arrays:

static char[] ReverseAllWords(char[] in_text)
{
    int lindex = 0;
    int rindex = in_text.Length - 1;
    if (rindex > 1)
    {
        //reverse complete phrase
        in_text = ReverseString(in_text, 0, rindex);

        //reverse each word in resultant reversed phrase
        for (rindex = 0; rindex <= in_text.Length; rindex++)
        {
            if (rindex == in_text.Length || in_text[rindex] == ' ')
            {
                in_text = ReverseString(in_text, lindex, rindex - 1);
                lindex = rindex + 1;
            }
        }
    }
    return in_text;
}

static char[] ReverseString(char[] intext, int lindex, int rindex)
{
    char tempc;
    while (lindex < rindex)
    {
        tempc = intext[lindex];
        intext[lindex++] = intext[rindex];
        intext[rindex--] = tempc;
    }
    return intext;
}

Sharing my notes which I usually maintain while reading from Internet, I hope it may be helpful to someone

Candidate Key or available keys

Candidate keys are those keys which is candidate for primary key of a table. In simple words we can understand that such type of keys which full fill all the requirements of primary key which is not null and have unique records is a candidate for primary key. So thus type of key is known as candidate key. Every table must have at least one candidate key but at the same time can have several.

Primary Key

Such type of candidate key which is chosen as a primary key for table is known as primary key. Primary keys are used to identify tables. There is only one primary key per table. In SQL Server when we create primary key to any table then a clustered index is automatically created to that column.

Foreign Key

Foreign key are those keys which is used to define relationship between two tables. When we want to implement relationship between two tables then we use concept of foreign key. It is also known as referential integrity. We can create more than one foreign key per table. Foreign key is generally a primary key from one table that appears as a field in another where the first table has a relationship to the second. In other words, if we had a table A with a primary key X that linked to a table B where X was a field in B, then X would be a foreign key in B.

Alternate Key or Secondary

If any table have more than one candidate key, then after choosing primary key from those candidate key, rest of candidate keys are known as an alternate key of that table. Like here we can take a very simple example to understand the concept of alternate key. Suppose we have a table named Employee which has two columns EmpID and EmpMail, both have not null attributes and unique value. So both columns are treated as candidate key. Now we make EmpID as a primary key to that table then EmpMail is known as alternate key.

Composite Key

When we create keys on more than one column then that key is known as composite key. Like here we can take an example to understand this feature. I have a table Student which has two columns Sid and SrefNo and we make primary key on these two column. Then this key is known as composite key.

Natural keys

A natural key is one or more existing data attributes that are unique to the business concept. For the Customer table there was two candidate keys, in this case CustomerNumber and SocialSecurityNumber. Link http://www.agiledata.org/essays/keys.html

Surrogate key

Introduce a new column, called a surrogate key, which is a key that has no business meaning. An example of which is the AddressID column of the Address table in Figure 1. Addresses don't have an "easy" natural key because you would need to use all of the columns of the Address table to form a key for itself (you might be able to get away with just the combination of Street and ZipCode depending on your problem domain), therefore introducing a surrogate key is a much better option in this case. Link http://www.agiledata.org/essays/keys.html

Unique key

A unique key is a superkey--that is, in the relational model of database organization, a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples (rows) that have the same values for the attributes in this set

Aggregate or Compound keys

When more than one column is combined to form a unique key, their combined value is used to access each row and maintain uniqueness. These keys are referred to as aggregate or compound keys. Values are not combined, they are compared using their data types.

Simple key

Simple key made from only one attribute.

Super key

A superkey is defined in the relational model as a set of attributes of a relation variable (relvar) for which it holds that in all relations assigned to that variable there are no two distinct tuples (rows) that have the same values for the attributes in this set. Equivalently a super key can also be defined as a set of attributes of a relvar upon which all attributes of the relvar are functionally dependent.

Partial Key or Discriminator key

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

GET and POST method set like this... Two types for api calling 1)get() and 2) post() . get() method to get value from api json array to get value & post() method use in our data post in url and get response.

Convert would be the normal answer, but the format is not a recognised format for the converter, mm/dd/yyyy could be converted using convert(datetime,yourdatestring,101) but you do not have that format so it fails.

The problem is the format being non-standard, you will have to manipulate it to a standard the convert can understand from those available.

Hacked together, if you can guarentee the format

declare @date char(8)
set @date = '12312009'
select convert(datetime, substring(@date,5,4) + substring(@date,1,2) + substring(@date,3,2),112)

I have a sample from your code. Try this:

echo "*Select Option:*"
echo "1 - script1"
echo "2 - script2"
echo "3 - script3 "
read option
echo "You have selected" $option"."
if [ $option="1" ]
then
    echo "1"
elif [ $option="2" ]
then
    echo "2"
    exit 0
elif [ $option="3" ]
then
    echo "3"
    exit 0
else
    echo "Please try again from given options only."
fi

This should work. :)

You can also use this old trick for converting complex if/then/else blocks into a slightly cleaner switch statement:

<div [ngSwitch]="true">
    <button (click)="foo=(++foo%3)+1">Switch!</button>

    <div *ngSwitchCase="foo === 1">one</div>
    <div *ngSwitchCase="foo === 2">two</div>
    <div *ngSwitchCase="foo === 3">three</div>
</div>

To get the file name portion of the file name, the basename method is used:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var file = path.basename(fileName);

console.log(file); // 'python.exe'

If you want the file name without the extension, you can pass the extension variable (containing the extension name) to the basename method telling Node to return only the name without the extension:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var extension = path.extname(fileName);
var file = path.basename(fileName,extension);

console.log(file); // 'python'

You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.

You just need to re-open the image with IrfanView after changing the view color to white.

To change the viewing color in Irfanview go to:

Options > Properties/Settings > Viewing > Main window color

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

To fix the issue for me (as a number of applications started to throw this exception all of a sudden, for example, CorelDraw X6 being one), I uninstalled the .NET 4.5 runtime and installed the .NET 4 runtime. The two versions cannot be installed side by side, but they use the same version numbers in the GAC. This causes issues as some of the functions have been depreciated in 4.5.

DLL Hell has returned...

if( char.toUpperCase() != char.toLowerCase() ) 

Will return true only in case of letter

As point out in below comment, if your character is non English, High Ascii or double byte range then you need to add check for code point.

if( char.toUpperCase() != char.toLowerCase() || char.codePointAt(0) > 127 )

I have to join the chorus recommending log4net, in my case coming from a platform flexibility (desktop .Net/Compact Framework, 32/64-bit) point of view.

However, wrapping it in a private-label API is a major anti-pattern. log4net.ILogger is the .Net counterpart of the Commons Logging wrapper API already, so coupling is already minimized for you, and since it is also an Apache library, that's usually not even a concern because you're not giving up any control: fork it if you must.

Most house wrapper libraries I've seen also commit one or more of a litany of faults:

42. Using a global singleton logger (or equivalently a static entry point) which loses the fine resolution of the recommended logger-per-class pattern for no other selectivity gain.
43. Failing to expose the optional Exception argument, leading to multiple problems:
    • It makes an exception logging policy even more difficult to maintain, so nothing is done consistently with exceptions.
    • Even with a consistent policy, formatting the exception away into a string loses data prematurely. I've written a custom ILayout decorator that performs detailed drill-down on an exception to determine the chain of events.
44. Failing to expose the IsLevelEnabled properties, which discards the ability to skip formatting code when areas or levels of logging are turned off.

It can now be changed to lambda version

@Override
public void actionPerformed(ActionEvent e) {
    Platform.runLater(() -> {
        try {
            //an event with a button maybe
            System.out.println("button is clicked");
        } catch (IOException | COSVisitorException ex) {
            Exceptions.printStackTrace(ex);
        }
    });
}

One option is to type [command] + [shift] + [p] (or the equivalent) and then type 'indentation'. The top result should be 'Indendtation: Reindent Lines'. Press [enter] and it will format the document.

Another option is to install the Emmet plugin (http://emmet.io/), which will provide not only better formatting, but also a myriad of other incredible features. To get the output you're looking for using Sublime Text 3 with the Emmet plugin requires just the following:

p [tab][enter] Hello world!

When you type p [tab] Emmet expands it to:

<p></p>

Pressing [enter] then further expands it to:

<p>

</p>

With the cursor indented and on the line between the tags. Meaning that typing text results in:

<p>
    Hello, world!
</p>

In XML 1.0, the XML Declaration is optional. See section 2.8 of the XML 1.0 Recommendation, where it says it "should" be used -- which means it is recommended, but not mandatory. In XML 1.1, however, the declaration is mandatory. See section 2.8 of the XML 1.1 Recommendation, where it says "MUST" be used. It even goes on to state that if the declaration is absent, that automatically implies the document is an XML 1.0 document.

Note that in an XML Declaration the encoding and standalone are both optional. Only the version is mandatory. Also, these are not attributes, so if they are present they must be in that order: version, followed by any encoding, followed by any standalone.

<?xml version="1.0"?>
<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" standalone="yes"?>
<?xml version="1.0" encoding="UTF-16" standalone="yes"?>

If you don't specify the encoding in this way, XML parsers try to guess what encoding is being used. The XML 1.0 Recommendation describes one possible way character encoding can be autodetected. In practice, this is not much of a problem if the input is encoded as UTF-8, UTF-16 or US-ASCII. Autodetection doesn't work when it encounters 8-bit encodings that use characters outside the US-ASCII range (e.g. ISO 8859-1) -- avoid creating these if you can.

The standalone indicates whether the XML document can be correctly processed without the DTD or not. People rarely use it. These days, it is a bad to design an XML format that is missing information without its DTD.

Update:

A "prolog error/invalid utf-8 encoding" error indicates that the actual data the parser found inside the file did not match the encoding that the XML declaration says it is. Or in some cases the data inside the file did not match the autodetected encoding.

Since your file contains a byte-order-mark (BOM) it should be in UTF-16 encoding. I suspect that your declaration says <?xml version="1.0" encoding="UTF-8"?> which is obviously incorrect when the file has been changed into UTF-16 by NotePad. The simple solution is to remove the encoding and simply say <?xml version="1.0"?>. You could also edit it to say encoding="UTF-16" but that would be wrong for the original file (which wasn't in UTF-16) or if the file somehow gets changed back to UTF-8 or some other encoding.

Don't bother trying to remove the BOM -- that's not the cause of the problem. Using NotePad or WordPad to edit XML is the real problem!

You can use inline assembly for the function call. (in this code I assume the arguments are characters).

void format_string(char *fmt, ...);
void debug_print(int dbg_level, int numOfArgs, char *fmt, ...)
    {
        va_list argumentsToPass;
        va_start(argumentsToPass, fmt);
        char *list = new char[numOfArgs];
        for(int n = 0; n < numOfArgs; n++)
            list[n] = va_arg(argumentsToPass, char);
        va_end(argumentsToPass);
        for(int n = numOfArgs - 1; n >= 0; n--)
        {
            char next;
            next = list[n];
            __asm push next;
        }
        __asm push fmt;
        __asm call format_string;
        fprintf(stdout, fmt);
    }

The accepted answer is the most perfect one but as some users has pointed that for cases where an element is repeated more than 2 times it will gives us the array with repeated elements:

This solution covers that scenarios too::

const peoples = [
  {id: 1, name:"Arjun"},
  {id: 2, name:"quinze"},
  {id: 3, name:"catorze"},
  {id: 1, name:"Arjun"},
  {id: 4, name:"dezesseis"},
  {id: 1, name:"Arjun"},
  {id: 2, name:"quinze"},
  {id: 3, name:"catorzee"}
]


function repeated(ppl){

  const newppl = ppl.slice().sort((a,b) => a.id -b.id);

  let rept = [];
  for(let i = 0; i < newppl.length-1 ; i++){
    if (newppl[i+1].id == newppl[i].id){
      rept.push(newppl[i+1]);
    }
  }

  return [...new Set(rept.map(el => el.id))].map(rid => 
    rept.find(el => el.id === rid)
  );

}

repeated(peoples);

I would say for Python at least, the self parameter can be thought of as a placeholder. Take a look at this:

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age

p1 = Person("John", 36)

print(p1.name)
print(p1.age)

Self in this case and a lot of others was used as a method to say store the name value. However, after that, we use the p1 to assign it to the class we're using. Then when we print it we use the same p1 keyword.

Hope this helps for Python!

From MYSQL I solved the problem like this:

SUM(CASE WHEN used = 1 THEN 1 ELSE 0 END) as amount_one,

Hope this helps :D

java.time

The modern approach uses the java.time classes that supplanted the troublesome legacy date-time classes bundled with the earliest versions of Java.

The java.sql.Timestamp class is one of those legacy classes. No longer needed. Instead use Instant or other java.time classes directly with your database using JDBC 4.2 and later.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myResultSet.getObject( … , Instant.class ) ; 

If you must interoperate with an existing Timestamp, convert immediately into java.time via the new conversion methods added to the old classes.

Instant instant = myTimestamp.toInstant() ;

To adjust into another time zone, specify the time zone as a ZoneId object. Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter pseudo-zones such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;

Apply to the Instant to produce a ZonedDateTime object.

ZonedDateTime zdt = instant.atZone( z ) ;

To generate a string for display to the user, search Stack Overflow for DateTimeFormatter to find many discussions and examples.

Your Question is really about going the other direction, from user data-entry to the date-time objects. Generally best to break your data-entry into two parts, a date and a time-of-day.

LocalDate ld = LocalDate.parse( dateInput , DateTimeFormatter.ofPattern( "M/d/uuuu" , Locale.US ) ) ;
LocalTime lt = LocalTime.parse( timeInput , DateTimeFormatter.ofPattern( "H:m a" , Locale.US ) ) ;

Your Question is not clear. Do you want to interpret the date and the time entered by the user to be in UTC? Or in another time zone?

If you meant UTC, create a OffsetDateTime with an offset using the constant for UTC, ZoneOffset.UTC.

OffsetDateTime odt = OffsetDateTime.of( ld , lt , ZoneOffset.UTC ) ;

If you meant another time zone, combine along with a time zone object, a ZoneId. But which time zone? You might detect a default time zone. Or, if critical, you must confirm with the user to be certain of their intention.

ZonedDateTime zdt = ZonedDateTime.of( ld , lt , z ) ;

To get a simpler object that is always in UTC by definition, extract an Instant.

Instant instant = odt.toInstant() ;

…or…

Instant instant = zdt.toInstant() ; 

Send to your database.

myPreparedStatement.setObject( … , instant ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

It declares a type based on what is assigned to it in the initialisation.

A simple example is that the code:

var i = 53;

Will examine the type of 53, and essentially rewrite this as:

int i = 53;

Note that while we can have:

long i = 53;

This won't happen with var. Though it can with:

var i = 53l; // i is now a long

Similarly:

var i = null; // not allowed as type can't be inferred.
var j = (string) null; // allowed as the expression (string) null has both type and value.

This can be a minor convenience with complicated types. It is more important with anonymous types:

var i = from x in SomeSource where x.Name.Length > 3 select new {x.ID, x.Name};
foreach(var j in i)
  Console.WriteLine(j.ID.ToString() + ":" + j.Name);

Here there is no other way of defining i and j than using var as there is no name for the types that they hold.

Just to clarify my comment (it's illegible in a single line)

I think the best answer is the comment by Mike Chambers in this link (http://www.judahfrangipane.com/blog/2007/02/15/error-2032-stream-error/) by Hunter McMillen.

A note from Mike Chambers:

If you run into this using URLLoader, listen for the:

flash.events.HTTPStatusEvent.HTTP_STATUS

and in AIR :

flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS

It should give you some more information (such as the status code being returned from the server).

1. Right-click on your project, select Maven -> Remove Maven Nature.

2. Open you terminal, go to your project folder and do mvn eclipse:clean

3. Right click on your Project and select “Configure -> Convert into Maven Project”

Now you got “Unsupported IClasspathEntry kind=4 Eclipse Scala” disappear.

The key is the margin: 0 auto; on the inner div. A proof-of-concept example:

Hello Optional World

If you want the runtime to supply a default parameter value, you have to use reflection to make the call. Not as nice as the other suggestions for this question, but compatible with VB.NET.

using System;
using System.Runtime.InteropServices;
using System.Reflection;

namespace ConsoleApplication1
{
    class Class1
    {
        public static void sayHelloTo(
            [Optional,
            DefaultParameterValue("world")] string whom)
        {
            Console.WriteLine("Hello " + whom);
        }

        [STAThread]
        static void Main(string[] args)
        {
            MethodInfo mi = typeof(Class1).GetMethod("sayHelloTo");
            mi.Invoke(null, new Object[] { Missing.Value });
        }
    }
}

Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

I had the same problem. You have to write mysql -u root -p

NOT mysql or mysql -u root -p root_password

Just as @Kabeer has mentioned, you can use TrimSpace and here is an example from golang documentation:

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Println(strings.TrimSpace(" \t\n Hello, Gophers \n\t\r\n"))
}

Let me try to make it simple, suppose URL of the site is http://example.com/ and let's suppose you need to sign up by filling username and password, so we go to the login page say http://example.com/login.php now and view it's source code and search for the action URL it will be in form tag something like

 <form name="loginform" method="post" action="userinfo.php">

now take userinfo.php to make absolute URL which will be 'http://example.com/userinfo.php', now run a simple python script

import requests
url = 'http://example.com/userinfo.php'
values = {'username': 'user',
          'password': 'pass'}

r = requests.post(url, data=values)
print r.content

I Hope that this helps someone somewhere someday.

HTML:

<div class="item row">
    <div class="col-xs-12 col-sm-6"><h4>This is some text.</h4></div>
    <div class="col-xs-12 col-sm-6"><h4>This is some more.</h4></div>
</div>

CSS:

div.item div h4 {
    height: 60px;
    vertical-align: middle;    
    display: table-cell;
}

Important notes:

• The vertical-align: middle; display: table-cell; must be applied to a tag that has no Bootstrap classes applied; it cannot be a col-*, a row, etc.
• This can't be done without this extra, possibly pointless tag in your HTML, unfortunately.
• The backgrounds are unnecessary - they're just there for demo purposes. So, you don't need to apply any special rules to the row or col-* tags.
• It is important to notice the inner tag does not stretch to 100% of the width of its parent; in our scenario this didn't matter but it may to you. If it does, you end up with something closer to some of the other answers here:

http://jsfiddle.net/b9chris/zN39r/1/

CSS:

div.item div {
    background: #fdd;
    table-layout: fixed;
    display: table;
}
div.item div h4 {
    height: 60px;
    vertical-align: middle;    
    display: table-cell;
    background: #eee;
}

Notice the added table-layout and display properties on the col-* tags. This must be applied to the tag(s) that have col-* applied; it won't help on other tags.

For one project, I needed so strip HTML, but also css and js. Thus, I made a variation of Eloffs answer:

class MLStripper(HTMLParser):
    def __init__(self):
        self.reset()
        self.strict = False
        self.convert_charrefs= True
        self.fed = []
        self.css = False
    def handle_starttag(self, tag, attrs):
        if tag == "style" or tag=="script":
            self.css = True
    def handle_endtag(self, tag):
        if tag=="style" or tag=="script":
            self.css=False
    def handle_data(self, d):
        if not self.css:
            self.fed.append(d)
    def get_data(self):
        return ''.join(self.fed)

def strip_tags(html):
    s = MLStripper()
    s.feed(html)
    return s.get_data()

By default you use curl without explicitly saying which request method to use. If you just pass in a HTTP URL like curl http://example.com it will use GET. If you use -d or -F curl will use POST, -I will cause a HEAD and -T will make it a PUT.

If for whatever reason you're not happy with these default choices that curl does for you, you can override those request methods by specifying -X [WHATEVER]. This way you can for example send a DELETE by doing curl -X DELETE [URL].

It is thus pointless to do curl -X GET [URL] as GET would be used anyway. In the same vein it is pointless to do curl -X POST -d data [URL]... But you can make a fun and somewhat rare request that sends a request-body in a GET request with something like curl -X GET -d data [URL].

Digging deeper

curl -GET (using a single dash) is just wrong for this purpose. That's the equivalent of specifying the -G, -E and -T options and that will do something completely different.

There's also a curl option called --get to not confuse matters with either. It is the long form of -G, which is used to convert data specified with -d into a GET request instead of a POST.

(I subsequently used my own answer here to populate the curl FAQ to cover this.)

Warnings

Modern versions of curl will inform users about this unnecessary and potentially harmful use of -X when verbose mode is enabled (-v) - to make users aware. Further explained and motivated in this blog post.

-G converts a POST + body to a GET + query

You can ask curl to convert a set of -d options and instead of sending them in the request body with POST, put them at the end of the URL's query string and issue a GET, with the use of `-G. Like this:

curl -d name=daniel -d grumpy=yes -G https://example.com/

I've your same requirements on a public API for which I used rails-api.

I've also set header in a before filter. It looks like this:

headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'

It seems you missed the Access-Control-Request-Method header.

String res =" Application " res=res.trim();

o/p: Application

Note: White space ,blank space are trim or removed

Try this, works in Ruby:

DateTime.now.to_time.utc

index(substring [, offset]) ? fixnum or nil
index(regexp [, offset]) ? fixnum or nil

Returns the index of the first occurrence of the given substring or pattern (regexp) in str. Returns nil if not found. If the second parameter is present, it specifies the position in the string to begin the search.

"hello".index('e')             #=> 1
"hello".index('lo')            #=> 3
"hello".index('a')             #=> nil
"hello".index(?e)              #=> 1
"hello".index(/[aeiou]/, -3)   #=> 4

Check out ruby documents for more information.

In newer versions of PHP, "extension_dir" is not initially enabled.

Try this one.

Sample Code

String str = " hello     there   ";
System.out.println(str.replaceAll("( +)"," ").trim());

OUTPUT

hello there

First it will replace all the spaces with single space. Than we have to supposed to do trim String because Starting of the String and End of the String it will replace the all space with single space if String has spaces at Starting of the String and End of the String So we need to trim them. Than you get your desired String.

Here's all the exception assertions you can do. Note that all of them are optional.

class ExceptionTest extends PHPUnit_Framework_TestCase
{
    public function testException()
    {
        // make your exception assertions
        $this->expectException(InvalidArgumentException::class);
        // if you use namespaces:
        // $this->expectException('\Namespace\MyExceptio??n');
        $this->expectExceptionMessage('message');
        $this->expectExceptionMessageRegExp('/essage$/');
        $this->expectExceptionCode(123);
        // code that throws an exception
        throw new InvalidArgumentException('message', 123);
   }

   public function testAnotherException()
   {
        // repeat as needed
        $this->expectException(Exception::class);
        throw new Exception('Oh no!');
    }
}

You can read file data line by line as below:

String fileLoc = "fileLocationInTheDisk";

List<String> lines = Files.lines(Path.of(fileLoc), StandardCharsets.UTF_8).collect(Collectors.toList());

You can also use Bootstrap 4 flex classes

Like: .align-item-center and .justify-content-center

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

For Java 8, You can have one more solution like below

List<String> list = new ArrayList<>();
String searchTerm = "dvd";

if(String.join(",", list).toLowerCase().contains(searchTerm)) {
  System.out.println("Element Present!");
}

Another way to run jar files with a click/double-click, is to prepend "-jar " to the file's name. For example, you would rename the file MyJar.jar to -jar MyJar.jar.

You must have the .class files associated with java.exe, of course. This might not work in all cases, but it has worked most times for me.

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

What

It is possible with EditorConfig.

EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs.

This also includes file encoding.

EditorConfig is built-in Visual Studio 2017 by default, and I there were plugins available for versions as old as VS2012. Read more from EditorConfig Visual Studio Plugin page.

How

You can set up a EditorConfig configuration file high enough in your folder structure to span all your intended repos (up to your drive root should your files be really scattered everywhere) and configure the setting charset:

charset: set to latin1, utf-8, utf-8-bom, utf-16be or utf-16le to control the character set.

You can add filters and exceptions etc on every folder level or by file name/type should you wish for finer control.

Once configured then compatible IDEs should automatically do it's thing to make matching files comform to set rules. Note that Visual Studio does not automatically convert all your files but do its bit when you work with files in IDE (open and save).

What next

While you could have a Visual-studio-wide setup, I strongly suggest to still include an EditorConfig root to your solution version control, so that explicit settings are automatically synced to all team members as well. Your drive root editorconfig file can be the fallback should some project not have their own editorconfig files set up yet.

Instead of delete the property, you can also create a new object with the keys that are not null.

const removeEmpty = (obj) => {
  return Object.keys(obj).filter(key => obj[key]).reduce(
    (newObj, key) => {
      newObj[key] = obj[key]
      return newObj
    }, {}
  )
}

Try this

If @NewStatus  = 'InOffice' 
BEGIN
     Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'OutOffice'
BEGIN
    Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'Home'
BEGIN
    Update tblEmployee set Home = -1 where EmpID = @EmpID
END

You can do this: git diff branch1:path/to/file branch2:path/to/file

If you have difftool configured, then you can also: git difftool branch1:path/to/file branch2:path/to/file

    if((s_numer > denom) == denom_positive || (t_numer > denom) == denom_positive) {
        return false;

    var t = t_numer / denom;

As Boltclock states in his answer to Selecting and manipulating CSS pseudo-elements such as ::before and ::after using jQuery

Although they are rendered by browsers through CSS as if they were like other real DOM elements, pseudo-elements themselves are not part of the DOM, and thus you can't select and manipulate them with jQuery.

Might just be best to set the style with jQuery instead of using the pseudo CSS selector.

Your question is a a bit vague. This is a shell command that does what I think you want to do:

echo >> name_of_file

• Use an OnClickListener in the button
• Add the ImageView to the layout or set the visibility of the ImageView to VISIBLE

Floating point numbers are encoded using an exponential form, that is something like m * b ^ e, i.e. not like integers at all. The question you ask would be meaningful in the context of fixed point numbers. There are numerous fixed point arithmetic libraries available.

Regarding floating point arithmetic: The number of decimal digits depends on the presentation and the number system. For example there are periodic numbers (0.33333) which do not have a finite presentation in decimal but do have one in binary and vice versa.

Also it is worth mentioning that floating point numbers up to a certain point do have a difference larger than one, i.e. value + 1 yields value, since value + 1 can not be encoded using m * b ^ e, where m, b and e are fixed in length. The same happens for values smaller than 1, i.e. all the possible code points do not have the same distance.

Because of this there is no precision of exactly n digits like with fixed point numbers, since not every number with n decimal digits does have a IEEE encoding.

There is a nearly obligatory document which you should read then which explains floating point numbers: What every computer scientist should know about floating point arithmetic.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

Although I guess you do not need an answer any longer, I am giving the solution for those who will come to see this post.

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

Do this, it works:

defaultConfig {
    applicationId "com.example.maps"
    minSdkVersion 15
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}

A nice version that works under Linux, BSD and MacOS X. First tries to send SIGTERM, and if it doesn't succeed, kills the process after 10 seconds.

KillJobs() {
    for job in $(jobs -p); do
            kill -s SIGTERM $job > /dev/null 2>&1 || (sleep 10 && kill -9 $job > /dev/null 2>&1 &)

    done
}

TrapQuit() {
    # Whatever you need to clean here
    KillJobs
}

trap TrapQuit EXIT

Please note that jobs does not include grand children processes.

The workaround for this is:

In your render function do something like this:

constructor() {
    this.state = { isLoading: true }
}

componentDidMount() {
    this.setState({isLoading: false})
}

render() {
    return(
        this.state.isLoading ? *showLoadingScreen* : *yourPage()*
    )
}

Initialize isLoading as true in the constructor and false on componentDidMount

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

Another very basic free profiler: http://expressprofiler.codeplex.com

After a bit of time (and more searching), I found this blog entry by Jomo Fisher.

One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

[Snip]

The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>
</startup>

So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy attribute reverts back to CLR 2.0 loading.

I think will work.

$('#DivID').height('675px');

If you use proxy, you will have to edit the Nuget.config file.

In Windows 7 and 10, this file is in the path:
C:\Users\YouUser\AppData\Roaming\NuGet.

Include the setting:

<config>
  <add key = "http_proxy" value = "http://Youproxy:8080" />
  <add key = "http_proxy.user" value = "YouProxyUser" />
</config>

Hope you dont mind Xml.Linq and .net3.5+

XElement ele = XElement.Load("text.xml");
String aXmlString = ele.toString(SaveOptions.DisableFormatting);

Depending on what you are interested in, you can probably skip the whole 'string' var part and just use XLinq objects

You can set it to NULL.

> Data$genome <- NULL
> head(Data)
   chr region
1 chr1    CDS
2 chr1   exon
3 chr1    CDS
4 chr1   exon
5 chr1    CDS
6 chr1   exon

As pointed out in the comments, here are some other possibilities:

Data[2] <- NULL    # Wojciech Sobala
Data[[2]] <- NULL  # same as above
Data <- Data[,-2]  # Ian Fellows
Data <- Data[-2]   # same as above

You can remove multiple columns via:

Data[1:2] <- list(NULL)  # Marek
Data[1:2] <- NULL        # does not work!

Be careful with matrix-subsetting though, as you can end up with a vector:

Data <- Data[,-(2:3)]             # vector
Data <- Data[,-(2:3),drop=FALSE]  # still a data.frame

Whenever you need to access property dynamically you have to use square bracket for accessing property not "." operator
Syntax: object[propery}

const something = { bar: "Foobar!" };_x000D_
const foo = 'bar';_x000D_
// something.foo; -- not correct way at it is expecting foo as proprty in  something={ foo: "value"};_x000D_
// correct way is  something[foo]_x000D_
alert( something[foo])

Finish() method will destroy the current activity. You can use this method in cases when you dont want this activity to load again and again when the user presses back button. Basically it clears the activity from the.current stack.

Consider a simple function that adds the first N natural numbers. (e.g. sum(5) = 1 + 2 + 3 + 4 + 5 = 15).

Here is a simple JavaScript implementation that uses recursion:

function recsum(x) {
    if (x === 1) {
        return x;
    } else {
        return x + recsum(x - 1);
    }
}

If you called recsum(5), this is what the JavaScript interpreter would evaluate:

recsum(5)
5 + recsum(4)
5 + (4 + recsum(3))
5 + (4 + (3 + recsum(2)))
5 + (4 + (3 + (2 + recsum(1))))
5 + (4 + (3 + (2 + 1)))
15

Note how every recursive call has to complete before the JavaScript interpreter begins to actually do the work of calculating the sum.

Here's a tail-recursive version of the same function:

function tailrecsum(x, running_total = 0) {
    if (x === 0) {
        return running_total;
    } else {
        return tailrecsum(x - 1, running_total + x);
    }
}

Here's the sequence of events that would occur if you called tailrecsum(5), (which would effectively be tailrecsum(5, 0), because of the default second argument).

tailrecsum(5, 0)
tailrecsum(4, 5)
tailrecsum(3, 9)
tailrecsum(2, 12)
tailrecsum(1, 14)
tailrecsum(0, 15)
15

In the tail-recursive case, with each evaluation of the recursive call, the running_total is updated.

Note: The original answer used examples from Python. These have been changed to JavaScript, since Python interpreters don't support tail call optimization. However, while tail call optimization is part of the ECMAScript 2015 spec, most JavaScript interpreters don't support it.

Personal preference.

Usually. Sometimes it matters but, not to seem like a jerk here, but if you have to ask, it probably doesn't.

I had a similar problem which I solved by changing the Port Settings in the port driver (located in Ports in device manager) to fit the device I was using.

For me it was that wrong Bits per second value was set.

I had the same problem. My work around is to use adb shell and su. Next, copy the file to /sdcard/Download

Then, I can use adb pull to get the file.

Here is an example of initializing a boolean[][]:

const n = 8; // or some dynamic value
const palindrome: boolean[][] = new Array(n)
                                   .fill(false)
                                   .map(() => new Array(n)
                                   .fill(false));

First, you can calculate the group means with aggregate:

means <- aggregate(weight ~  group, PlantGrowth, mean)

This dataset can be used with geom_text:

library(ggplot2)
ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) + geom_boxplot() +
  stat_summary(fun.y=mean, colour="darkred", geom="point", 
               shape=18, size=3,show_guide = FALSE) + 
  geom_text(data = means, aes(label = weight, y = weight + 0.08))

Here, + 0.08 is used to place the label above the point representing the mean.

An alternative version without ggplot2:

means <- aggregate(weight ~  group, PlantGrowth, mean)

boxplot(weight ~ group, PlantGrowth)
points(1:3, means$weight, col = "red")
text(1:3, means$weight + 0.08, labels = means$weight)

You could use DATE_ADD : (or ADDDATE with INTERVAL)

UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR) 

Just to share my idea...

I created a custom class to inherit the Label class. I added a private variable assigned as a Tooltip class and a public property, TooltipText. Then, gave it a MouseEnter delegate method. This is an easy way to work with multiple Label controls and not have to worry about assigning your Tooltip control for each Label control.

    public partial class ucLabel : Label
    {
        private ToolTip _tt = new ToolTip();

        public string TooltipText { get; set; }

        public ucLabel() : base() {
            _tt.AutoPopDelay = 1500;
            _tt.InitialDelay = 400;
//            _tt.IsBalloon = true;
            _tt.UseAnimation = true;
            _tt.UseFading = true;
            _tt.Active = true;
            this.MouseEnter += new EventHandler(this.ucLabel_MouseEnter);
        }

        private void ucLabel_MouseEnter(object sender, EventArgs ea)
        {
            if (!string.IsNullOrEmpty(this.TooltipText))
            {
                _tt.SetToolTip(this, this.TooltipText);
                _tt.Show(this.TooltipText, this.Parent);
            }
        }
    }

In the form or user control's InitializeComponent method (the Designer code), reassign your Label control to the custom class:

this.lblMyLabel = new ucLabel();

Also, change the private variable reference in the Designer code:

private ucLabel lblMyLabel;

Use this query to get Schema, Table, Column,Type, max_length, is_nullable

SELECT QUOTENAME(SCHEMA_NAME(tb.[schema_id])) AS 'Schema'
    ,QUOTENAME(OBJECT_NAME(tb.[OBJECT_ID])) AS 'Table'
    ,C.NAME as 'Column'
    ,T.name AS 'Type'
    ,C.max_length
    ,C.is_nullable
FROM SYS.COLUMNS C INNER JOIN SYS.TABLES tb ON tb.[object_id] = C.[object_id]
    INNER JOIN SYS.TYPES T ON C.system_type_id = T.user_type_id
WHERE tb.[is_ms_shipped] = 0
ORDER BY tb.[Name]

The reason your CSS isn't working is because of specificity. The Bootstrap selector has a higher specificity than yours, so your style is completely ignored.

Bootstrap styles this with the selector: .navbar-default .navbar-toggle .icon-bar. This selector has a B specificity value of 3, whereas yours only has a B specificity value of 1.

Therefore, to override this, simply use the same selector in your CSS (assuming your CSS is included after Bootstrap's):

.navbar-default .navbar-toggle .icon-bar {
    background-color: black;
}

Just query the "memberOf" property and iterate though the return, example:

            search.PropertiesToLoad.Add("memberOf");
            StringBuilder groupNames = new StringBuilder(); //stuff them in | delimited

                SearchResult result = search.FindOne();
                int propertyCount = result.Properties["memberOf"].Count;
                String dn;
                int equalsIndex, commaIndex;

                for (int propertyCounter = 0; propertyCounter < propertyCount;
                    propertyCounter++)
                {
                    dn = (String)result.Properties["memberOf"][propertyCounter];

                    equalsIndex = dn.IndexOf("=", 1);
                    commaIndex = dn.IndexOf(",", 1);
                    if (-1 == equalsIndex)
                    {
                        return null;
                    }
                    groupNames.Append(dn.Substring((equalsIndex + 1),
                                (commaIndex - equalsIndex) - 1));
                    groupNames.Append("|");
                }

            return groupNames.ToString();

This just stuffs the group names into the groupNames string, pipe delimited, but when you spin through you can do whatever you want with them

MY SOLUTION!!!!!!! I fixed this problem when I was trying to install business objects. When the installer failed to register .dll's I inputted the MSVCR71.dll into both system32 and sysWOW64 then clicked retry. Installation finished. I did try adding this in before and after install but, install still failed.

The best way to use https and avoid security issues is to use Firefox (or another tool) and download the certificate to your server. This webpage helped me a lot, and these were the steps that worked for me:

1) Open in Firefox the URL you're gonna use with CURL

2) On the address bar click on the padlock > more information (FF versions can have different menus, just find it). Click the View certificate button > Details tab.

3) Highlight the "right" certificate in Certificate hierarchy. In my case it was the second of three, called "cPanel, Inc. Certification Authority". I just discovered the right one by "trial and error" method.

4) Click the Export button. In my case the one who worked was the file type "PEM with chains" (again by trial and error method).

5) Then in your PHP script add:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);    
curl_setopt($ch, CURLOPT_CAINFO, [PATH_TO_CRT_FILE]);

In addition I'd say that we must pay attention on the fact that these steps will probably need to be redone once a year or whenever the URL certificate is replaced or renewed.

To view the files just browse them from the command prompt (cmd), eg.:

c:\>cd \Windows\assembly\GAC_32
c:\Windows\assembly\GAC_32> dir

To add and remove files from the GAC use the tool gacutil

Python doesn't have such types as you describe. There are two types used to represent integral values: int, which corresponds to platform's int type in C, and long, which is an arbitrary precision integer (i.e. it grows as needed and doesn't have an upper limit). ints are silently converted to long if an expression produces result which cannot be stored in int.

In a few words: catch the exception.

I am really surprised nobody answered or commented about Exception Catch on this post yet.

Detail: Here goes an example where I try to match a function which is prefixed by mask_ and suffixed by the form field "name". When JavaScript does not find the function, it should throw an ReferenceError which you can handle as you wish on the catch section.

function inputMask(input) {_x000D_
  try {_x000D_
    let maskedInput = eval("mask_"+input.name);_x000D_
_x000D_
    if(typeof maskedInput === "undefined")_x000D_
        return input.value;_x000D_
    else_x000D_
        return eval("mask_"+input.name)(input);_x000D_
_x000D_
  } catch(e) {_x000D_
    if (e instanceof ReferenceError) {_x000D_
      return input.value;_x000D_
    }_x000D_
  }_x000D_
}

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

Sure, you could use an enum. Would something like the following work?

enum Alignment {
    LEFT,
    RIGHT
}

private static String drawCellValue(int maxCellLength, String cellValue, Alignment alignment) { }

If you wanted to use a boolean, you could rename the align parameter to something like alignLeft. I agree that this implementation is not as clean, but if you don't anticipate a lot of changes and this is not a public interface, it might be a good choice.

In CSS3 paged media this is possible using position: running() and content: element().

Example from the CSS Generated Content for Paged Media Module draft:

@top-center {
  content: element(heading); 
}

.runner { 
  position: running(heading);
}

.runner can be any element and heading is an arbitrary name for the slot.

EDIT: to clarify, there is basically no browser support so this was mostly meant to be for future reference/in addition to the 'practical answers' given already.

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

If you work in Java you may try VBAMacroExtractor. After extracting VBA scripts from .xlsm I've found there password in plaintext.

I had this annoying issue since I upgraded my VS 2019 to 16.4.3 and caused me a lot of headache.
Finally I solved the problem this way:

1. Stop Debugging
2. Select the solution from "Solution Explorer"
3. In the Properties window change the "Active config" Property From "Release|Any CPU" To "Debug|Any CPU"
4. In Debug > Options > General Check the Edit and Continue checkbox

That worked for me, and hope it works for you too.

I have been in similar situation before. In Command prompt, you type 'start-ssh-agent' and voila! The ssh-agent will be started. Input the passphrase if it asked you.

Even after these tries. My website images were fetched some times and sometimes not. After validating with https://developers.facebook.com/tools/debug/sharing

realised that my django (python) framework is rendering the image path relatively. I had to make changes to the path of the image with full url. (including http://). then it started working

Based on Mohamed23gharbi's answer:

function change(selector, value) {
    var sortBySelect = document.querySelector(selector);
    sortBySelect.value = value;
    sortBySelect.dispatchEvent(new Event("change"));
}

function click(selector) {
    var sortBySelect = document.querySelector(selector);
    sortBySelect.dispatchEvent(new Event("click"));
}

function test() {
    change("select#MySelect", 19);
    click("button#MyButton");
    click("a#MyLink");
}

In my case, where the elements were created by vue, this is the only way that works.

It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.

You can also use joblib.dump and joblib.load which is much more efficient at handling numerical arrays than the default python pickler.

Joblib is included in scikit-learn:

>>> import joblib
>>> from sklearn.datasets import load_digits
>>> from sklearn.linear_model import SGDClassifier

>>> digits = load_digits()
>>> clf = SGDClassifier().fit(digits.data, digits.target)
>>> clf.score(digits.data, digits.target)  # evaluate training error
0.9526989426822482

>>> filename = '/tmp/digits_classifier.joblib.pkl'
>>> _ = joblib.dump(clf, filename, compress=9)

>>> clf2 = joblib.load(filename)
>>> clf2
SGDClassifier(alpha=0.0001, class_weight=None, epsilon=0.1, eta0=0.0,
       fit_intercept=True, learning_rate='optimal', loss='hinge', n_iter=5,
       n_jobs=1, penalty='l2', power_t=0.5, rho=0.85, seed=0,
       shuffle=False, verbose=0, warm_start=False)
>>> clf2.score(digits.data, digits.target)
0.9526989426822482

Edit: in Python 3.8+ it's now possible to use pickle for efficient pickling of object with large numerical arrays as attributes if you use pickle protocol 5 (which is not the default).

To post JSON, you will need to stringify it. JSON.stringify and set the processData option to false.

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    processData: false,
    contentType: "application/json; charset=UTF-8",
    complete: callback
});

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI

You could try with OpenNew and then with Write but that's a bit strange use of that class. More info on MSDN.

As in a similar question, use display: inline-block with a placeholder element to vertically center the span inside of a block element:

html, body, #container, #placeholder { height: 100%; }_x000D_
_x000D_
#content, #placeholder { display:inline-block; vertical-align: middle; }

<!doctype html>_x000D_
<html lang="en">_x000D_
  <head>_x000D_
  </head>_x000D_
_x000D_
  <body>_x000D_
    <div id="container">_x000D_
      <span id="content">_x000D_
        Content_x000D_
      </span>_x000D_
      <span id="placeholder"></span>_x000D_
    </div>_x000D_
  </body>_x000D_
</html>

Vertical alignment is only applied to inline elements or table cells, so use it along with display:inline-block or display:table-cell with a display:table parent when vertically centering block elements.

open come to play when dealing with multiple modules.

open class is accessible and subclassable outside of the defining module. An open class member is accessible and overridable outside of the defining module.

You can use SELECT as lambacck said or add parentheses:

SET @times = (SELECT COUNT(DidWin)as "I Win"
FROM thetable
WHERE DidWin = 1 AND Playername='Me');

If you are a programmer, many XML parsing programming libraries will let you parse XML, then output it - and generating pretty printed, indented output is an output option.

Setting option 1 in the select element can be done by this segment. To visually show it, you have tp add .trigger('change') at the end.

$('#name').removeAttr('selected').find('option:first').attr('selected', 'selected').trigger("change");

Take a look at this post: http://praveenbattula.blogspot.com/2009/09/access-iframe-content-using-jquery.html

$("#iframeID").contents().find("[tokenid=" + token + "]").html();

Place your selector in the find method.

While it was primarly designed for the browser, it works well with Jaxer and Rhino.

I don't know node.js yet but if you can cache some JS and functions in memory, the speed should be even more impressive.

The key here is that you say "If I type in a URL directly...".

By default under forms authentication the browser caches pages for the user. So, selecting a URL directly from the browsers address box dropdown, or typing it in, MAY get the page from the browser's cache, and never go back to the server to check authentication/authorization. The solution to this is to prevent client-side caching in the Page_Load event of each page, or in the OnLoad() of your base page:

Response.Cache.SetCacheability(HttpCacheability.NoCache);

You might also like to call:

Response.Cache.SetNoStore();

This might be a dead horse, another way to return 1 row when no rows exist is to UNION another query and display results when non exist in the table.

SELECT S.Status, COUNT(s.id) AS StatusCount
FROM Sites S
WHERE S.Id = @SiteId
GROUP BY s.Status
UNION ALL --UNION BACK ON TABLE WITH NOT EXISTS
SELECT 'N/A' AS Status, 0 AS StatusCount
WHERE NOT EXISTS (SELECT 1
   FROM Sites S
   WHERE S.Id = @SiteId
) 

I'm not aware if you can create a migration from the command line to do all this, but you can create a new migration, then edit the migration to perform this taks.

If tablename is the name of your table, fieldname is the name of your field and you want to change from a datetime to date, you can write a migration to do this.

You can create a new migration with:

rails g migration change_data_type_for_fieldname

Then edit the migration to use change_table:

class ChangeDataTypeForFieldname < ActiveRecord::Migration
  def self.up
    change_table :tablename do |t|
      t.change :fieldname, :date
    end
  end
  def self.down
    change_table :tablename do |t|
      t.change :fieldname, :datetime
    end
  end
end

Then run the migration:

rake db:migrate

You usually don't want to do this. With Docker Compose you define services that compose your app. npm and manage.py are just management commands. You don't need a container for them. If you need to, say create your database tables with manage.py, all you have to do is:

docker-compose run client python manage.py create_db

Think of it as the one-off dynos Heroku uses.

If you really need to treat these management commands as separate containers (and also use Docker Compose for these), you could create a separate .yml file and start Docker Compose with the following command:

docker-compose up -f my_custom_docker_compose.yml

Type the following in the linux/ubuntu terminal

 crontab -e 

select an editor (sometime it asks for the editor) and this to run for every minute

*       *       *       *       *       /usr/bin/php path/to/cron.php &> /dev/null

In addition to user701648's answer, you can store your credentials in your home folder (global for all projects), instead of project folder using the following command

$ git config --global credential.helper store
$ git push http://example.com/repo.git
Username: <type your username>
Password: <type your password>

Don't know if this will be everybody's answer, but after some digging, here's what we came up with.

The error is obviously caused by the fact that the listener was not accepting connections, but why would we get that error when other tests could connect fine (we could also connect no problem through sqlplus)? The key to the issue wasn't that we couldn't connect, but that it was intermittent

After some investigation, we found that there was some static data created during the class setup that would keep open connections for the life of the test class, creating new ones as it went. Now, even though all of the resources were properly released when this class went out of scope (via a finally{} block, of course), there were some cases during the run when this class would swallow up all available connections (okay, bad practice alert - this was unit test code that connected directly rather than using a pool, so the same problem could not happen in production).

The fix was to not make that class static and run in the class setup, but instead use it in the per method setUp and tearDown methods.

So if you get this error in your own apps, slap a profiler on that bad boy and see if you might have a connection leak. Hope that helps.

5.In the Format Cells box, click Custom in the Category list. 6.In the Type box, at the top of the list of formats, type [h]:mm;@ and then click OK. (That’s a colon after [h], and a semicolon after mm.) YOu can then add hours. The format will be in the Type list the next time you need it.

From MS, works well.

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

Your additional threads must be initiated from the same app that is called by the WSGI server.

The example below creates a background thread that executes every 5 seconds and manipulates data structures that are also available to Flask routed functions.

import threading
import atexit
from flask import Flask

POOL_TIME = 5 #Seconds

# variables that are accessible from anywhere
commonDataStruct = {}
# lock to control access to variable
dataLock = threading.Lock()
# thread handler
yourThread = threading.Thread()

def create_app():
    app = Flask(__name__)

    def interrupt():
        global yourThread
        yourThread.cancel()

    def doStuff():
        global commonDataStruct
        global yourThread
        with dataLock:
        # Do your stuff with commonDataStruct Here

        # Set the next thread to happen
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()   

    def doStuffStart():
        # Do initialisation stuff here
        global yourThread
        # Create your thread
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()

    # Initiate
    doStuffStart()
    # When you kill Flask (SIGTERM), clear the trigger for the next thread
    atexit.register(interrupt)
    return app

app = create_app()          

Call it from Gunicorn with something like this:

gunicorn -b 0.0.0.0:5000 --log-config log.conf --pid=app.pid myfile:app

I think you want something like this:

public class Person {

  private int age;

  //public method to get the age variable
  public int getAge(){
       return this.age
  }

  //public method to set the age variable
  public void setAge(int age){
       this.age = age;
  }
}

You're simply calling such a method on an object instance. Such methods are useful especially if setting something is supposed to have side effects. E.g. if you want to react to certain events like:

  public void setAge(int age){

       this.age = age;

       double averageCigarettesPerYear = this.smokedCigarettes * 1.0 / age;

       if(averageCigarettesPerYear >= 7300.0) {
           this.eventBus.fire(new PersonSmokesTooMuchEvent(this));
       }
  }

Of course this can be dangerous if somebody forgets to call setAge(int) where he should and sets age directly using this.age.

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

There are a lot of great answers here. While there are usually quick solutions to the problem, some of which feel more pythonic than others, if you have the luxury of doing some refactoring, another approach is to analyze the organization of your code, and try to remove the circular dependency. You may find, for example, that you have:

File a.py

from b import B

class A:
    @staticmethod
    def save_result(result):
        print('save the result')

    @staticmethod
    def do_something_a_ish(param):
        A.save_result(A.use_param_like_a_would(param))

    @staticmethod
    def do_something_related_to_b(param):
        B.do_something_b_ish(param)

File b.py

from a import A

class B:
    @staticmethod
    def do_something_b_ish(param):
        A.save_result(B.use_param_like_b_would(param))

In this case, just moving one static method to a separate file, say c.py:

File c.py

def save_result(result):
    print('save the result')

will allow removing the save_result method from A, and thus allow removing the import of A from a in b:

Refactored File a.py

from b import B
from c import save_result

class A:
    @staticmethod
    def do_something_a_ish(param):
        A.save_result(A.use_param_like_a_would(param))

    @staticmethod
    def do_something_related_to_b(param):
        B.do_something_b_ish(param)

Refactored File b.py

from c import save_result

class B:
    @staticmethod
    def do_something_b_ish(param):
        save_result(B.use_param_like_b_would(param))

In summary, if you have a tool (e.g. pylint or PyCharm) that reports on methods that can be static, just throwing a staticmethod decorator on them might not be the best way to silence the warning. Even though the method seems related to the class, it might be better to separate it out, especially if you have several closely related modules that might need the same functionality and you intend to practice DRY principles.

If you are using Linux, you can use this bash script: (it perhaps needs some additional code cleaning but it works ... and it's much faster then mysqldump|mysql)

#!/bin/bash

DBUSER=user
DBPASSWORD=pwd
DBSNAME=sourceDb
DBNAME=destinationDb
DBSERVER=db.example.com

fCreateTable=""
fInsertData=""
echo "Copying database ... (may take a while ...)"
DBCONN="-h ${DBSERVER} -u ${DBUSER} --password=${DBPASSWORD}"
echo "DROP DATABASE IF EXISTS ${DBNAME}" | mysql ${DBCONN}
echo "CREATE DATABASE ${DBNAME}" | mysql ${DBCONN}
for TABLE in `echo "SHOW TABLES" | mysql $DBCONN $DBSNAME | tail -n +2`; do
        createTable=`echo "SHOW CREATE TABLE ${TABLE}"|mysql -B -r $DBCONN $DBSNAME|tail -n +2|cut -f 2-`
        fCreateTable="${fCreateTable} ; ${createTable}"
        insertData="INSERT INTO ${DBNAME}.${TABLE} SELECT * FROM ${DBSNAME}.${TABLE}"
        fInsertData="${fInsertData} ; ${insertData}"
done;
echo "$fCreateTable ; $fInsertData" | mysql $DBCONN $DBNAME

I find internal to be far overused. you really should not be exposing certain functionailty only to certain classes that you would not to other consumers.

This in my opinion breaks the interface, breaks the abstraction. This is not to say it should never be used, but a better solution is to refactor to a different class or to be used in a different way if possible. However, this may not be always possible.

The reasons it can cause issues is that another developer may be charged with building another class in the same assembly that yours is. Having internals lessens the clarity of the abstraction, and can cause problems if being misused. It would be the same issue as if you made it public. The other class that is being built by the other developer is still a consumer, just like any external class. Class abstraction and encapsulation isnt just for protection for/from external classes, but for any and all classes.

Another problem is that a lot of developers will think they may need to use it elsewhere in the assembly and mark it as internal anyways, even though they dont need it at the time. Another developer then may think its there for the taking. Typically you want to mark private until you have a definative need.

But some of this can be subjective, and I am not saying it should never be used. Just use when needed.

Cast it back to its original type, which will be a DataRowView if you're binding a table, and you can then get the Id and Text from the appropriate columns:

foreach(object itemChecked in checkedListBox1.CheckedItems)
{
     DataRowView castedItem = itemChecked as DataRowView;
     string comapnyName = castedItem["CompanyName"];
     int? id = castedItem["ID"];
}

If you use Anaconda, you may try:

conda install Pillow

Example

 public function addGetParamToUrl($url, $params)
{
    foreach ($params as $param) {
         if (strpos($url, "?"))
        {
            $url .= "&" .http_build_query($param); 
        }
        else
        {
            $url .= "?" .http_build_query($param); 
        }
    }
    return $url;
}

SELECT * 
FROM people 
WHERE names ='SMITH'
ORDER BY names asc
limit 10

If you need add group by clause. If you search Smith you would have to sort on something else.

SQL Server also accepts the simpler notation of:

SELECT A.F, 
       B.G, 
       C.H 
  FROM TABLE_A A, 
       TABLE_B B, 
       TABLE_C C
 WHERE A.X = B.X 
   AND B.Y = C.Y

Using this simpler notation, one does not need to bother about the difference between inner and cross joins. Instead of two "ON" clauses, there is a single "WHERE" clause that does the job. If you have any difficulty in figuring out which "JOIN" "ON" clauses go where, abandon the "JOIN" notation and use the simpler one above.

It is not cheating.

next() and nextLine() methods are associated with Scanner and is used for getting String inputs. Their differences are...

next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.

nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.

import java.util.Scanner;

public class temp
{
    public static void main(String arg[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("enter string for c");
        String c=sc.next();
        System.out.println("c is "+c);
        System.out.println("enter string for d");
        String d=sc.next();
        System.out.println("d is "+d);
    }
}

Output:

enter string for c abc def
c is abc

enter string for d

d is def

If you use nextLine() instead of next() then

Output:

enter string for c

ABC DEF
c is ABC DEF
enter string for d

GHI
d is GHI

In terms of how this is implemented, this changes the method - from OrderBy/ThenBy to OrderByDescending/ThenByDescending. However, you can apply the sort separately to the main query...

var qry = from .... // or just dataList.AsEnumerable()/AsQueryable()

if(sortAscending) {
    qry = qry.OrderBy(x=>x.Property);
} else {
    qry = qry.OrderByDescending(x=>x.Property);
}

Any use? You can create the entire "order" dynamically, but it is more involved...

Another trick (mainly appropriate to LINQ-to-Objects) is to use a multiplier, of -1/1. This is only really useful for numeric data, but is a cheeky way of achieving the same outcome.

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

Produces a shallow copy as a hash object of just the model attributes

my_hash_gift = gift.attributes.dup

Check the type of the resulting object

my_hash_gift.class
=> Hash

This will depend on the device you're using. If you're using a pdf device, you can do this:

pdf( "mygraph.pdf", width = 11, height = 8 )
plot( x, y )

You can then divide up the space in the pdf using the mfrow parameter like this:

par( mfrow = c(2,2) )

That makes a pdf with four panels available for plotting. Unfortunately, some of the devices take different units than others. For example, I think that X11 uses pixels, while I'm certain that pdf uses inches. If you'd just like to create several devices and plot different things to them, you can use dev.new(), dev.list(), and dev.next().

Other devices that might be useful include:

• X11
• postscript
• BMP, JPEG, PNG and TIFF
• quartz (OSX only)

There's a list of all of the devices here.

For IE8 or console support limited to console.log (no debug, trace, ...) you can do the following:

• If console OR console.log undefined: Create dummy functions for console functions (trace, debug, log, ...)

  window.console = { debug : function() {}, ...};

• Else if console.log is defined (IE8) AND console.debug (any other) is not defined: redirect all logging functions to console.log, this allows to keep those logs !

  window.console = { debug : window.console.log, ...};

Not sure about the assert support in various IE versions, but any suggestions are welcome. Also posted this answer here: How can I use console logging in Internet Explorer?

initialize the Session class in the constructor of controller using

$this->load->library('session');

for example :

 function __construct()
   {
    parent::__construct();
    $this->load->model('user','',TRUE);
    $this->load->model('user_activity','',TRUE);
    $this->load->library('session');
   }

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

I restarted my computer and then opened the IDE again and it worked while none of the above did.

Maybe you have to do the things above as well, but make sure to restart the computer too.

use the runas command. But, I don't think you can email a .bat file easily.

One way to achieve this is to add a DefaultDocument settings in the Web.config.

  <system.webServer>
   <defaultDocument>
    <files>
      <clear />
      <add value="DefaultPage.aspx" />
    </files>
   </defaultDocument>
  </system.webServer>

Very late, but here is the answer you want:

https://api.github.com/repos/ [git username] / [git project] /releases

Next, find the id of the project you are looking for in the data. It should be near the top, next to the urls. Then, navigate to

https://api.github.com/repos/ [git username] / [git project] /releases/ [id] / assets

The field named download_count is your answer.

EDIT: Capitals matter in your username and project name

Assuming two decimal places on your percentages, the data type you use depends on how you plan to store your percentages. If you are going to store their fractional equivalent (e.g. 100.00% stored as 1.0000), I would store the data in a decimal(5,4) data type with a CHECK constraint that ensures that the values never exceed 1.0000 (assuming that is the cap) and never go below 0 (assuming that is the floor). If you are going to store their face value (e.g. 100.00% is stored as 100.00), then you should use decimal(5,2) with an appropriate CHECK constraint. Combined with a good column name, it makes it clear to other developers what the data is and how the data is stored in the column.

Using this HTML:

<div id="myElement" style="position: absolute">This stays at the top</div>

This is the javascript you want to use. It attaches an event to the window's scroll and moves the element down as far as you've scrolled.

$(window).scroll(function() {
    $('#myElement').css('top', $(this).scrollTop() + "px");
});

As pointed out in the comments below, it's not recommended to attach events to the scroll event - as the user scrolls, it fires A LOT, and can cause performance issues. Consider using it with Ben Alman's debounce/throttle plugin to reduce overhead.

To do this cross browser including IE7+, you will need to expand the plugin with a transformation matrix. Since vendor prefix is done in jQuery from jquery-1.8+ I will leave that out for the transform property.

$.fn.animateRotate = function(endAngle, options, startAngle)
{
    return this.each(function()
    {
        var elem = $(this), rad, costheta, sintheta, matrixValues, noTransform = !('transform' in this.style || 'webkitTransform' in this.style || 'msTransform' in this.style || 'mozTransform' in this.style || 'oTransform' in this.style),
            anims = {}, animsEnd = {};
        if(typeof options !== 'object')
        {
            options = {};
        }
        else if(typeof options.extra === 'object')
        {
            anims = options.extra;
            animsEnd = options.extra;
        }
        anims.deg = startAngle;
        animsEnd.deg = endAngle;
        options.step = function(now, fx)
        {
            if(fx.prop === 'deg')
            {
                if(noTransform)
                {
                    rad = now * (Math.PI * 2 / 360);
                    costheta = Math.cos(rad);
                    sintheta = Math.sin(rad);
                    matrixValues = 'M11=' + costheta + ', M12=-'+ sintheta +', M21='+ sintheta +', M22='+ costheta;
                    $('body').append('Test ' + matrixValues + '<br />');
                    elem.css({
                        'filter': 'progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\','+matrixValues+')',
                        '-ms-filter': 'progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\','+matrixValues+')'
                    });
                }
                else
                {
                    elem.css({
                        //webkitTransform: 'rotate('+now+'deg)',
                        //mozTransform: 'rotate('+now+'deg)',
                        //msTransform: 'rotate('+now+'deg)',
                        //oTransform: 'rotate('+now+'deg)',
                        transform: 'rotate('+now+'deg)'
                    });
                }
            }
        };
        if(startAngle)
        {
            $(anims).animate(animsEnd, options);
        }
        else
        {
            elem.animate(animsEnd, options);
        }
    });
};

Note: The parameters options and startAngle are optional, if you only need to set startAngle use {} or null for options.

Example usage:

var obj = $(document.createElement('div'));
obj.on("click", function(){
    obj.stop().animateRotate(180, {
        duration: 250,
        complete: function()
        {
            obj.animateRotate(0, {
                duration: 250
            });
        }
    });
});
obj.text('Click me!');
obj.css({cursor: 'pointer', position: 'absolute'});
$('body').append(obj);

See also this jsfiddle for a demo.

Update: You can now also pass extra: {} in the options. This will make you able to execute other animations simultaneously. For example:

obj.animateRotate(90, {extra: {marginLeft: '100px', opacity: 0.5}});

This will rotate the element 90 degrees, and move it to the right with 100px and make it semi-transparent all at the same time during the animation.

The problem here is in your explode statement

//$item['date'] presumably = 20120514.  Do a print of this
$eventDate = trim($item['date']);

//This explodes on , but there is no , in $eventDate
//You also have a limit of 2 set in the below explode statement
$myarray = (explode(',', $eventDate, 2));

 //$myarray is currently = to '20'

 foreach ($myarray as $value) {
    //Now you are iterating through a string
    echo $value;
 }

Try changing your initial $item['date'] to be 2012,04,30 if that's what you're trying to do. Otherwise I'm not entirely sure what you're trying to print.

You could use an asymmetrical border to make curves with CSS.

border-radius: 50%/100px 100px 0 0;

This is a very strange question to ask, specifically of python, so being more specific will definitely help me answer it. As is, I'll try to take a stab at it.

I'm going to assume what you want to do is create a new instance of a datastructure and give it a variable. For this example I'll use the dictionary data structure and the variable mydictionary.

mydictionary = dict()

This will create a new instance of the dictionary data structure and place it in the variable named mydictionary. Alternatively the dictionary constructor can also take arguments:

mydictionary = dict([('sape', 4139), ('guido', 4127), ('jack', 4098)])

Finally, python will attempt to figure out what data structure I mean from the data I give it. IE

mydictionary = {'jack': 4098, 'sape': 4139}

These examples were taken from Here

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

Newer JDK already has AbstractCollection.toString() implemented, and Stack extends AbstractCollection so you just have to call toString() on your collection:

    public abstract class AbstractCollection<E> implements Collection<E> {
    ...
    public String toString() {
        Iterator<E> it = iterator();
        if (! it.hasNext())
            return "[]";
    
        StringBuilder sb = new StringBuilder();
        sb.append('[');
        for (;;) {
            E e = it.next();
            sb.append(e == this ? "(this Collection)" : e);
            if (! it.hasNext())
                return sb.append(']').toString();
            sb.append(',').append(' ');
        }
    }

This happens because of your application does not allow to append iframe from origin other than your application domain.

If your application have web.config then add the following tag in web.config

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="X-Frame-Options" value="ALLOW" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

This will allow application to append iframe from other origin also. You can also use the following value for X-Frame-Option

X-FRAME-OPTIONS: ALLOW-FROM https://example.com/ 

This might be 6 years late, but in Python 3.5 and above, you declare a variable type like this:

variable_name: type_name

or this:

variable_name # type: shinyType

So in your case(if you have a CustomObject class defined), you can do:

customObj: CustomObject

See this or that for more info.

Simply my project wasn't in htdocs thats why it was showing me an this error make sure you put your project in HTdocs not in directory inside it

find builds a list of files. It applies the predicate you supplied to each one and returns those that pass.

This idea that -prune means exclude from results was really confusing for me. You can exclude a file without prune:

find -name 'bad_guy' -o -name 'good_guy' -print  // good_guy

All -prune does is alter the behavior of the search. If the current match is a directory, it says "hey find, that file you just matched, dont descend into it". It just removes that tree (but not the file itself) from the list of files to search.

It should be named -dont-descend.

Most of the other solutions count duplicates. If you really need to group key value pairs, try this:

Here is my example data:

find . | xargs md5sum
fe4ab8e15432161f452e345ff30c68b0 a.txt
30c68b02161e15435ff52e34f4fe4ab8 b.txt
30c68b02161e15435ff52e34f4fe4ab8 c.txt
fe4ab8e15432161f452e345ff30c68b0 d.txt
fe4ab8e15432161f452e345ff30c68b0 e.txt

This will print the key value pairs grouped by the md5 checksum.

cat table.txt | awk '{print $1}' | sort | uniq  | xargs -i grep {} table.txt
30c68b02161e15435ff52e34f4fe4ab8 b.txt
30c68b02161e15435ff52e34f4fe4ab8 c.txt
fe4ab8e15432161f452e345ff30c68b0 a.txt
fe4ab8e15432161f452e345ff30c68b0 d.txt
fe4ab8e15432161f452e345ff30c68b0 e.txt

select{
    filter: progid:DXImageTransform.Microsoft.dropshadow(OffX=-1, OffY=-1,color=#FF0000) progid:DXImageTransform.Microsoft.dropshadow(OffX=1, OffY=1,color=#FF0000);
}

Works for me.

I extended @nathanielperales solution.

Below the behavior description:

• click the map to enable scroll
• when mouse leaves the map, disable scroll

Below the javascript code:

// Disable scroll zooming and bind back the click event
var onMapMouseleaveHandler = function (event) {
  var that = $(this);

  that.on('click', onMapClickHandler);
  that.off('mouseleave', onMapMouseleaveHandler);
  that.find('iframe').css("pointer-events", "none");
}

var onMapClickHandler = function (event) {
  var that = $(this);

  // Disable the click handler until the user leaves the map area
  that.off('click', onMapClickHandler);

  // Enable scrolling zoom
  that.find('iframe').css("pointer-events", "auto");

  // Handle the mouse leave event
  that.on('mouseleave', onMapMouseleaveHandler);
}

// Enable map zooming with mouse scroll when the user clicks the map
$('.maps.embed-container').on('click', onMapClickHandler);

And here is an jsFiddle example.

protected void TestSubmit_ServerClick(object sender, EventArgs e)
{
  using (StreamWriter _testData = new StreamWriter(Server.MapPath("~/data.txt"), true))
 {
  _testData.WriteLine(TextBox1.Text); // Write the file.
 }         
}

Server.MapPath takes a virtual path and returns an absolute one. "~" is used to resolve to the application root.

Try this. Create a shortcut in startup folder and iuput

PowerShell "&.'PathToFile\script.ps1'"

This is the easiest way.

Remember in Java a quoted String is still a String object. Therefore you can use the String function contains() to test for a range of Strings or integers using this method:

if ("A C Viking G M Ocelot".contains(mAnswer)) {...}

for numbers it's a tad more involved but still works:

if ("1 4 5 9 10 17 23 96457".contains(String.valueOf(mNumAnswer))) {...} 

I have solved a similar problem using external native lib dependencies that are packaged inside of jar files. Sometimes these architecture dependend libraries are packaged alltogether inside one jar, sometimes they are split up into several jar files. so i wrote some buildscript to scan the jar dependencies for native libs and sort them into the correct android lib folders. Additionally this also provides a way to download dependencies that not found in maven repos which is currently usefull to get JNA working on android because not all native jars are published in public maven repos.

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

You can install multiple versions of Python one machine, and during setup, you can choose to have one of them associate itself with Python file extensions. If you install modules, there will be different setup packages for different versions, or you can choose which version you want to target. Since they generally install themselves into the site-packages directory of the interpreter version, there shouldn't be any conflicts (but I haven't tested this). To choose which version of python, you would have to manually specify the path to the interpreter if it is not the default one. As far as I know, they would share the same PATH and PYTHONPATH variables, which may be a problem.

Note: I run Windows XP. I have no idea if any of this changes for other versions, but I don't see any reason that it would.

Instead of using your script tag defining the source of your .js file in <head>, place it at the bottom of your HTML code.

Here is a ruby class for performing this: https://gist.github.com/4080793

Example usage:

$ gem install aws-sdk
$ irb -r ./bucket_sync_service.rb
> from_creds = {aws_access_key_id:"XXX",
                aws_secret_access_key:"YYY",
                bucket:"first-bucket"}
> to_creds = {aws_access_key_id:"ZZZ",
              aws_secret_access_key:"AAA",
              bucket:"first-bucket"}
> syncer = BucketSyncService.new(from_creds, to_creds)
> syncer.debug = true # log each object
> syncer.perform

I was having a problem getting my ASP.NET 5.0/MVC 6 app to serve static binary file types or browse virtual directories. It looks like this is now done in Configure() at startup. See http://docs.asp.net/en/latest/fundamentals/static-files.html for a quick primer.

Another way could be to use json.dumps(X, sort_keys=True) option:

import json
a, b = json.dumps(a, sort_keys=True), json.dumps(b, sort_keys=True)
a == b # a normal string comparison

This works for nested dictionaries and lists.

Does the -verbose flag to your java command yield any useful info? If not, maybe java -X reveals something specific to your version that might help?

I had this issue when trying to concatenate getdate() into a string that I was inserting into an nvarchar field.

I did some casting to get around it:

 INSERT INTO [SYSTEM_TABLE] ([SYSTEM_PROP_TAG],[SYSTEM_PROP_VAL]) VALUES 
   (
    'EMAIL_HEADER',
    '<h2>111 Any St.<br />Anywhere, ST 11111</h2><br />' + 
        CAST(CAST(getdate() AS datetime2) AS nvarchar) + 
    '<br /><br /><br />'
   )

That's a sanitized example. The key portion of that is:

...' + CAST(CAST(getdate() AS datetime2) AS nvarchar) + '...

Casted the date as datetime2, then as nvarchar to concatenate it.

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

Scroll element to center of container

To bring the element to the center of the container.

DEMO on CODEPEN

JS

function scrollToCenter() {
  var container = $('.container'),
    scrollTo = $('.5');

  container.animate({
    //scrolls to center
    scrollTop: scrollTo.offset().top - container.offset().top + scrollTo.scrollTop() - container.height() / 2
  });
}

HTML

<div class="container">
   <div class="1">
    1
  </div>
  <div class="2">
    2
  </div>
  <div class="3">
    3
  </div>
  <div class="4">
    4
  </div>
  <div class="5">
    5
  </div>
  <div class="6">
    6
  </div>
  <div class="7">
    7
  </div>
  <div class="8">
    8
  </div>
  <div class="9">
    9
  </div>
  <div class="10">
    10
  </div>


</div>
<br>
<br>
<button id="scroll" onclick="scrollToCenter()">
  Scroll
</button>

css

.container {
  height: 60px;
  overflow-y: scroll;
  width 60px;
  background-color: white;
}

It is not exact to the center but you will not recognice it on larger bigger elements.

For someone whoe still struggle with the problem. According this article I used this sample and it works for me:

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'X264')
out = cv2.VideoWriter('output.mp4',fourcc, 20.0, (640,480))

while(cap.isOpened()):
    ret, frame = cap.read()
    if ret==True:
        frame = cv2.flip(frame,0)

        # write the flipped frame
        out.write(frame)

        cv2.imshow('frame',frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    else:
        break

# Release everything if job is finished
cap.release()
out.release()
cv2.destroyAllWindows()

So I had to use cv2.VideoWriter_fourcc(*'X264') codec. Tested with OpenCV 3.4.3 compiled from sources.

Somewhere around r59 this gets easier (rotate around x):

bb.GraphicsEngine.prototype.calcRotation = function ( obj, rotationX)
{
    var euler = new THREE.Euler( rotationX, 0, 0, 'XYZ' );
    obj.position.applyEuler(euler);
}

Use body-parser Parse the body with what it will be:

app.use(bodyParser.text());

app.use(bodyParser.urlencoded());

app.use(bodyParser.raw());

app.use(bodyParser.json());

ie. If you are supposed to get raw text file, run .text().

Thats what body-parser currently supports

find . -name '*.pyc' -print0 | xargs -0 rm

The find recursively looks for *.pyc files. The xargs takes that list of names and sends it to rm. The -print0 and the -0 tell the two commands to seperate the filenames with null characters. This allows it to work correctly on file names containing spaces, and even a file name containing a new line.

The solution with -exec works, but it spins up a new copy of rm for every file. On a slow system or with a great many files, that'll take too long.

You could also add a couple more args:

find . -iname '*.pyc' -print0 | xargs -0 --no-run-if-empty  rm

iname adds case insensitivity, like *.PYC . The no-run-if-empty keeps you from getting an error from rm if you have no such files.

if you have class with id and you want to filter by id

line1 : you mape all the id

line2: filter what is not exist in the map

Set<String> mapId = entityResponse.getEntities().stream().map(Entity::getId).collect(Collectors.toSet());

List<String> entityNotExist = entityValues.stream().filter(n -> !mapId.contains(n.getId())).map(DTOEntity::getId).collect(Collectors.toList());

Old question, but alternatively:

virtualenv --python=python3.5 .venv
source .venv/bin/activate

It's entirely possible if your code has enough relative logic to work with.

Simply use the viewport units though for some the math may be a bit more complicated. I used this to prevent list items from bloating certain table columns with much longer text.

ol {max-width: 10vw; padding: 0; overflow: hidden;}

Apparently max-width on colgroup elements do not work which is pretty lame to be dependent entirely on child elements to control something on the parent.

On Windows use:

C:\PostgreSQL\pg10\bin>createuser -U postgres --pwprompt <USER>

Add --superuser or --createdb as appropriate.

See https://www.postgresql.org/docs/current/static/app-createuser.html for further options.

Okay, so this post is from six months ago, but I thought I would add some info here for people who are confused about the whole API key/MD5 fingerprint business. It took me a while to figure out, so I assume others have had trouble with it too (unless I'm just that dull).

These directions are for Windows XP, but I imagine it is similar for other versions of Windows. It appears Mac and Linux users have an easier time with this so I won't address them.

So in order to use mapviews in your Android apps, Google wants to check in with them so you can sign off on an Android Maps APIs Terms Of Service agreement. I think they don't want you to make any turn-by-turn GPS apps to compete with theirs or something. I didn't really read it. Oops.

So go to http://code.google.com/android/maps-api-signup.html and check it out. They want you to check the "I have read and agree with the terms and conditions" box and enter your certificate's MD5 fingerprint. Wtf is that, you might say. I don't know, but just do what I say and your Android app doesn't get hurt.

Go to Start>Run and type cmd to open up a command prompt. You need to navigate to the directory with the keytool.exe file, which might be in a slightly different place depending on which version JDK you have installed. Mine is in C:\Program Files\Java\jdk1.6.0_21\bin but try browsing to the Java folder and see what version you have and change the path accordingly.

After navigating to C:\Program Files\Java\<"your JDK version here">\bin in the command prompt, type

keytool -list -keystore "C:/Documents and Settings/<"your user name here">/.android/debug.keystore"

with the quotes. Of course <"your user name here"> would be your own Windows username.

(If you are having trouble finding this path and you are using Eclipse, you can check Window>preferences>Android>Build and check out the "Default Debug keystore")

Press enter and it will prompt you for a password. Just press enter. And voila, at the bottom is your MD5 fingerprint. Type your fingerprint into the text box at the Android Maps API Signup page and hit Generate API Key.

And there's your key in all its glory, with a handy sample xml layout with your key entered for you to copy and paste.

Way1 :

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames = "column1"),@UniqueConstraint(columnNames = "column2")})

-- Here both Column1 and Column2 acts as unique constraints separately. Ex : if any time either the value of column1 or column2 value matches then you will get UNIQUE_CONSTRAINT Error.

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames ={"column1","column2"})})

-- Here both column1 and column2 combined values acts as unique constraints

Take a look at http://www.csharp-examples.net/download-files/ and msdn docs on webclient http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx

My suggestion is try the synchronous download as its more straightforward. you might get ideas on whether webclient parameters are wrong or the file is in incorrect format while trying this.

Here is a code sample..

private void btnDownload_Click(object sender, EventArgs e)
{
  string filepath = textBox1.Text;
  WebClient webClient = new WebClient();
  webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
  webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
  webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), filepath);
}

private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
  progressBar.Value = e.ProgressPercentage;
}

private void Completed(object sender, AsyncCompletedEventArgs e)
{
  MessageBox.Show("Download completed!");
}

One liner, attach one or many new cascading rule(s) to the document.

This example attach a cursor:pointer to every button, input, select.

document.body.appendChild(Object.assign(document.createElement("style"), {textContent: "select, button, input {cursor:pointer}"

html code

Django code:


Inside views.py


def view(request):

    if request.method == 'POST':
        print request.body
        data = request.body
        return HttpResponse(json.dumps(data))

Faced more issues while making this work. Here are the details:

1. To download and add apache-log4j-extras-1.1.jar in the classpath, didn't notice this at first.
2. The RollingFileAppender should be org.apache.log4j.rolling.RollingFileAppender instead of org.apache.log4j.RollingFileAppender. This can give the error: log4j:ERROR No output stream or file set for the appender named [file].
3. We had to upgrade the log4j library from log4j-1.2.14.jar to log4j-1.2.16.jar.

Below is the appender configuration which worked for me:

<appender name="file" class="org.apache.log4j.rolling.RollingFileAppender">
        <param name="threshold" value="debug" />
        <rollingPolicy name="file"
            class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="FileNamePattern" value="logs/MyLog-%d{yyyy-MM-dd-HH-mm}.log.gz" />
            <!-- The below param will keep the live update file in a different location-->
            <!-- param name="ActiveFileName" value="current/MyLog.log" /-->
        </rollingPolicy>

        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%5p %d{ISO8601} [%t][%x] %c - %m%n" />
        </layout>
</appender>
