Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

If you want to print all the columns in your select clause you can go with the autoprint command.

CREATE OR REPLACE PROCEDURE sps_detail_dtest(v_refcur OUT sys_refcursor)
AS
BEGIN
  OPEN v_refcur FOR 'select * from dummy_table';
END;

SET autoprint on;

--calling the procedure
VAR vcur refcursor;
DECLARE 
BEGIN
  sps_detail_dtest(vrefcur=>:vcur);
END;

Hope this gives you an alternate solution

Just add this to your global CSS style:

a { cursor: pointer; }

This way you're not dependent on the browser default cursor style anymore.

You could also sidestep nested cursor issues, general cursor issues, and global variable issues by avoiding the cursors entirely.

declare @rowid int
declare @rowid2 int
declare @id int
declare @type varchar(10)
declare @rows int
declare @rows2 int
declare @outer table (rowid int identity(1,1), id int, type varchar(100))
declare @inner table (rowid int  identity(1,1), clientid int, whatever int)

insert into @outer (id, type) 
Select id, type from sometable

select @rows = count(1) from @outer
while (@rows > 0)
Begin
    select top 1 @rowid = rowid, @id  = id, @type = type
    from @outer
    insert into @innner (clientid, whatever ) 
    select clientid whatever from contacts where contactid = @id
    select @rows2 = count(1) from @inner
    while (@rows2 > 0)
    Begin
        select top 1 /* stuff you want into some variables */
        /* Other statements you want to execute */
        delete from @inner where rowid = @rowid2
        select @rows2 = count(1) from @inner
    End  
    delete from @outer where rowid = @rowid
    select @rows = count(1) from @outer
End

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

$( document.activeElement )

Will retrieve it without having to search the whole DOM tree as recommended on the jQuery documentation

cursor.fetchall() and list(cursor) are essentially the same. The different option is to not retrieve a list, and instead just loop over the bare cursor object:

for result in cursor:

This can be more efficient if the result set is large, as it doesn't have to fetch the entire result set and keep it all in memory; it can just incrementally get each item (or batch them in smaller batches).

Here's my variant. Pretty much just like all the others, but I only use one variable to manage the looping.

DECLARE
  @LoopId  int
 ,@MyData  varchar(100)

DECLARE @CheckThese TABLE
 (
   LoopId  int  not null  identity(1,1)
  ,MyData  varchar(100)  not null
 )


INSERT @CheckThese (MyData)
 select MyData from MyTable
 order by DoesItMatter

SET @LoopId = @@rowcount

WHILE @LoopId > 0
 BEGIN
    SELECT @MyData = MyData
     from @CheckThese
     where LoopId = @LoopId

    --  Do whatever

    SET @LoopId = @LoopId - 1
 END

Raj More's point is relevant--only perform loops if you have to.

With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:

function getCaret(node) {
  if (node.selectionStart) {
    return node.selectionStart;
  } else if (!document.selection) {
    return 0;
  }

  var c = "\001",
      sel = document.selection.createRange(),
      dul = sel.duplicate(),
      len = 0;

  dul.moveToElementText(node);
  sel.text = c;
  len = dul.text.indexOf(c);
  sel.moveStart('character',-1);
  sel.text = "";
  return len;
}

(complete code here)

I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...

Edit: I actually re-implemented the above code:

function getCaret(el) { 
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
        rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    return rc.text.length; 
  }  
  return 0; 
}

Check an example here.

For Windows Forms applications an optional disabling of a UI-Control can be very useful. So my suggestion looks like this:

public class AppWaitCursor : IDisposable
{
    private readonly Control _eventControl;

    public AppWaitCursor(object eventSender = null)
    {
         _eventControl = eventSender as Control;
        if (_eventControl != null)
            _eventControl.Enabled = false;

        Application.UseWaitCursor = true;
        Application.DoEvents();
    }

    public void Dispose()
    {
        if (_eventControl != null)
            _eventControl.Enabled = true;

        Cursor.Current = Cursors.Default;
        Application.UseWaitCursor = false;
    }
}

Usage:

private void UiControl_Click(object sender, EventArgs e)
{
    using (new AppWaitCursor(sender))
    {
        LongRunningCall();
    }
}

My first suggestion would be use your calendar table, if you don't have one, then create one. They are very useful. Your query is then as simple as:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  Date
FROM    dbo.Calendar
WHERE   Date >= @MinDate
AND     Date < @MaxDate;

If you don't want to, or can't create a calendar table you can still do this on the fly without a recursive CTE:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1)
        Date = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @MinDate)
FROM    sys.all_objects a
        CROSS JOIN sys.all_objects b;

For further reading on this see:

• Generate a set or sequence without loops – part 1
• Generate a set or sequence without loops – part 2
• Generate a set or sequence without loops – part 3

With regard to then using this sequence of dates in a cursor, I would really recommend you find another way. There is usually a set based alternative that will perform much better.

So with your data:

  date   | it_cd | qty 
24-04-14 |  i-1  | 10 
26-04-14 |  i-1  | 20

To get the quantity on 28-04-2014 (which I gather is your requirement), you don't actually need any of the above, you can simply use:

SELECT  TOP 1 date, it_cd, qty 
FROM    T
WHERE   it_cd = 'i-1'
AND     Date <= '20140428'
ORDER BY Date DESC;

If you don't want it for a particular item:

SELECT  date, it_cd, qty 
FROM    (   SELECT  date, 
                    it_cd, 
                    qty, 
                    RowNumber = ROW_NUMBER() OVER(PARTITION BY ic_id 
                                                    ORDER BY date DESC)
            FROM    T
            WHERE   Date  <= '20140428'
        ) T
WHERE   RowNumber = 1;

For SQL Server 2005 onwards, you can do this with CROSS APPLY and a table-valued function.

• Using CROSS APPLY in SQL Server 2005

Just for clarity, I'm referring to those cases where the stored procedure can be converted into a table valued function.

You don't need jQuery for this. Here's a simple working example:

<!DOCTYPE html>
<html>
    <head>
        <title>box-shadow-experiment</title>
        <style type="text/css">
            #box-shadow-div{
                position: fixed;
                width: 1px;
                height: 1px;
                border-radius: 100%;
                background-color:black;
                box-shadow: 0 0 10px 10px black;
                top: 49%;
                left: 48.85%;
            }
        </style>
        <script type="text/javascript">
            window.onload = function(){
                var bsDiv = document.getElementById("box-shadow-div");
                var x, y;
    // On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
                window.addEventListener('mousemove', function(event){
                    x = event.clientX;
                    y = event.clientY;                    
                    if ( typeof x !== 'undefined' ){
                        bsDiv.style.left = x + "px";
                        bsDiv.style.top = y + "px";
                    }
                }, false);
            }
        </script>
    </head>
    <body>
        <div id="box-shadow-div"></div>
    </body>
</html>

I chose position: fixed; so scrolling wouldn't be an issue.

In case anyone else stumbles across this question, this is probably what you were looking for:

.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

 /* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

A more general approach would be to set the UIView's appearance's tintColor.

UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];

Makes sense if you're using many default UI elements.

Using inline styling use <a href="your link here" style="cursor:default">your content here</a>. See this example

Alternatively use css. See this example.

This solution is cross-browser compatible.

Try This

SELECT @PrimaryContactKey = c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey 
    AND i.invckey = @tmp_key

UPDATE tarinvoice SET confirmtocntctkey = @PrimaryContactKey 
WHERE invckey = @tmp_key
FETCH NEXT FROM @get_invckey INTO @tmp_key

You would declare this variable outside of your loop as just a standard TSQL variable.

I should also note that this is how you would do it for any type of select into a variable, not just when dealing with cursors.

1)your id should have sys dba access 2)

select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, 
 s.username, s.machine
 from v$sesstat a, v$statname b, v$session s 
 where a.statistic# = b.statistic# and s.sid=a.sid
 and b.name = 'opened cursors current' 
 group by s.username, s.machine
 order by 1 desc;

This issue can happen not only in eclipse but also in any of the text-editor.

On windows systems, windows-10 in my case, this issue arose when the shift and insert key was pressed in tandem unintentionally which takes the user to the overwrite mode.

To get back to insert mode you need to press shift and insert in tandem again.

How about using foreach loop:

Cursor cursor;
for (Cursor c : CursorUtils.iterate(cursor)) {
    //c.doSth()
}

However my version of CursorUtils should be less ugly, but it automatically closes the cursor:

public class CursorUtils {
public static Iterable<Cursor> iterate(Cursor cursor) {
    return new IterableWithObject<Cursor>(cursor) {
        @Override
        public Iterator<Cursor> iterator() {
            return new IteratorWithObject<Cursor>(t) {
                @Override
                public boolean hasNext() {
                    t.moveToNext();
                    if (t.isAfterLast()) {
                        t.close();
                        return false;
                    }
                    return true;
                }
                @Override
                public Cursor next() {
                    return t;
                }
                @Override
                public void remove() {
                    throw new UnsupportedOperationException("CursorUtils : remove : ");
                }
                @Override
                protected void onCreate() {
                    t.moveToPosition(-1);
                }
            };
        }
    };
}

private static abstract class IteratorWithObject<T> implements Iterator<T> {
    protected T t;
    public IteratorWithObject(T t) {
        this.t = t;
        this.onCreate();
    }
    protected abstract void onCreate();
}

private static abstract class IterableWithObject<T> implements Iterable<T> {
    protected T t;
    public IterableWithObject(T t) {
        this.t = t;
    }
}
}

Look at this page: http://www.webcodingtech.com/javascript/change-cursor.php. Looks like you can access cursor off of style. This page shows it being done with the entire page, but I'm sure a child element would work just as well.

document.body.style.cursor = 'wait';

Here's one possible method.

function isMouseInBox(e) {
  var textbox = document.getElementById('textbox');

  // Box position & sizes
  var boxX = textbox.offsetLeft;
  var boxY = textbox.offsetTop;
  var boxWidth = textbox.offsetWidth;
  var boxHeight = textbox.offsetHeight;

  // Mouse position comes from the 'mousemove' event
  var mouseX = e.pageX;
  var mouseY = e.pageY;
  if(mouseX>=boxX && mouseX<=boxX+boxWidth) {
    if(mouseY>=boxY && mouseY<=boxY+boxHeight){
       // Mouse is in the box
       return true;
    }
  }
}

document.addEventListener('mousemove', function(e){
    isMouseInBox(e);
})

It wasn't working because your image was too big - there are restrictions on the image dimensions. In Firefox, for example, the size limit is 128x128px. See this page for more details.

Additionally, you also have to add in auto.

jsFiddle demo here - note that's an actual image, and not a default cursor.

.test {_x000D_
  background:gray;_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
  cursor:url(http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif), auto;_x000D_
}

<div class="test">TEST</div>

If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149

To summarize, open up a Terminal window and type the following command:

defaults write NSGlobalDomain KeyRepeat -int 0

More detail from the article:

Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:

defaults write NSGlobalDomain KeyRepeat -int 0

Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.

You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.

I know this answer comes late, but I can see people havent found an answer. To prevent the up key to put the cursor at the start, just return false from the method handling the event. This stops the event chain that leads to the cursor movement. Pasting revised code from the OP below:

$(document).keydown(function(e) {
  var key   = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
  var input = self.shell.find('input.current:last');

  switch(key) {
    case 38: // up
      lastQuery = self.queries[self.historyCounter-1];
      self.historyCounter--;
      input.val(lastQuery).focus();
      // HERE IS THE FIX:
      return false; 
// and it continues on from there

Cursors make people overly apply a procedural mindset to a set-based environment.

And they are SLOW!!!

From SQLTeam:

Please note that cursors are the SLOWEST way to access data inside SQL Server. The should only be used when you truly need to access one row at a time. The only reason I can think of for that is to call a stored procedure on each row. In the Cursor Performance article I discovered that cursors are over thirty times slower than set based alternatives.

You can just do:

print(command_stdout.decode('utf-8'))

The answer provided by vsync works as long as you don't have accented letters in the input string.

I don't know the reason, but apparently the \b in regexp matches also accented letters (tested on IE8 and Chrome), so a string like "località" would be wrongly capitalized converted into "LocalitÀ" (the à letter gets capitalized cause the regexp thinks it's a word boundary)

A more general function that works also with accented letters is this one:

String.prototype.toCapitalize = function()
{ 
   return this.toLowerCase().replace(/^.|\s\S/g, function(a) { return a.toUpperCase(); });
}

You can use it like this:

alert( "hello località".toCapitalize() );

This happens because the current account you have used to log in probably has very limited priviledges.

To fix this problem, you can change your the AllowNoPassword config setting to false in config.inc.php. You may also force the authentication to use the config file and specify the default username and password .

$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; // leave blank if no password

After this, the PhPMyAdmin login page should show up when you refresh the page. You can then log in with the default root password.

More details can be found on this post ..

Well there are a few ways to go about this depending on the intended behavior, but this link should give you all the best solutions and not surprisingly is from Dianne Hackborn

http://groups.google.com/group/android-developers/browse_thread/thread/d2a5c203dad6ec42

Essentially you have the following options

• Use a name for your initial back stack state and use FragmentManager.popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• Use FragmentManager.getBackStackEntryCount()/getBackStackEntryAt().getId() to retrieve the ID of the first entry on the back stack, and FragmentManager.popBackStack(int id, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• FragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE) is supposed to pop the entire back stack... I think the documentation for that is just wrong. (Actually I guess it just doesn't cover the case where you pass in POP_BACK_STACK_INCLUSIVE),

for (var i = 0; i < 10; i = i + 2) {
    // code here
}?

What I do is I try to reset hard to HEAD. This will wipe out all the local commits:

git reset --hard HEAD^

pkill  <process id>
userdel <username>

1. Unicode

There're lots of characters around the world,like "$,&,h,a,t,?,?,1,=,+...".

Then there comes an organization who's dedicated to these characters,

They made a standard called "Unicode".

The standard is like follows:

• create a form in which each position is called "code point",or"code position".
• The whole positions are from U+0000 to U+10FFFF;
• Up until now,some positions are filled with characters,and other positions are saved or empty.
• For example,the position "U+0024" is filled with the character "$".

PS:Of course there's another organization called ISO maintaining another standard --"ISO 10646",nearly the same.

2. UTF-8

As above,U+0024 is just a position,so we can't save "U+0024" in computer for the character "$".

There must be an encoding method.

Then there come encoding methods,such as UTF-8,UTF-16,UTF-32,UCS-2....

Under UTF-8,the code point "U+0024" is encoded into 00100100.

00100100 is the value we save in computer for "$".

I've developed jmxfuse which exposes JMX Mbeans as a Linux FUSE filesystem with similar functionality as the /proc fs. It relies on Jolokia as the bridge to JMX. Attributes and operations are exposed for reading and writing.

http://code.google.com/p/jmxfuse/

For example, to read an attribute:

me@oddjob:jmx$ cd log4j/root/attributes
me@oddjob:jmx$ cat priority

to write an attribute:

me@oddjob:jmx$ echo "WARN" > priority

to invoke an operation:

me@oddjob:jmx$ cd Catalina/none/none/WebModule/localhost/helloworld/operations/addParameter
me@oddjob:jmx$ echo "myParam myValue" > invoke

For simple cases like this, TimeUnit should be used. TimeUnit usage is a bit more explicit about what is being represented and is also much easier to read and write when compared to doing all of the arithmetic calculations explicitly. For example, to calculate the number days from milliseconds, the following statement would work:

    long days = TimeUnit.MILLISECONDS.toDays(milliseconds);

For cases more advanced, where more finely grained durations need to be represented in the context of working with time, an all encompassing and modern date/time API should be used. For JDK8+, java.time is now included (here are the tutorials and javadocs). For earlier versions of Java joda-time is a solid alternative.

If anyone using MS SQL Server 2008 and higher lands on this question: SQL Server 2008 and higher has a new "hierarchyId" feature designed specifically for this task.

It tells the compiler the boundary to align objects in a structure to. For example, if I have something like:

struct foo { 
    char a;
    int b;
};

With a typical 32-bit machine, you'd normally "want" to have 3 bytes of padding between a and b so that b will land at a 4-byte boundary to maximize its access speed (and that's what will typically happen by default).

If, however, you have to match an externally defined structure you want to ensure the compiler lays out your structure exactly according to that external definition. In this case, you can give the compiler a #pragma pack(1) to tell it not to insert any padding between members -- if the definition of the structure includes padding between members, you insert it explicitly (e.g., typically with members named unusedN or ignoreN, or something on that order).

Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) in another cell and then pressing CTRL+SHIFT+ENTER.

Using CTRL+SHIFT+ENTER tells Excel to treat the formula as an "array formula". In this example, that means that the IF statement returns an array of 6 values (one of each of the cells in the range $A$1:$A$6) instead of a single value. The MEDIAN function then returns the median of these values. See http://www.cpearson.com/excel/arrayformulas.aspx for a similar example using AVERAGE instead of MEDIAN.

Seems like this sounds more complicated than it is...

    Dim myArray As String() = TextBox1.Lines
    'First we count how many null elements there are...
    Dim Counter As Integer = 0
    For x = 0 To myArray.Count - 1
        If Len(myArray(x)) < 1 Then
            Counter += 1
        End If
    Next
    'Then we dimension an array to be the size of the last array
    'minus the amount of nulls found...
    Dim tempArr(myArray.Count - Counter) As String

    'Indexing starts at zero, so let's set the stage for that...
    Counter = -1

    For x = 0 To myArray.Count - 1
        'Set the conditions for the new array as in
        'It .contains("word"), has no value, length is less than 1, ect.
        If Len(myArray(x)) > 1 Then
            Counter += 1
            'So if a value is present, we move that value over to
            'the new array.
            tempArr(Counter) = myArray(x)
        End If
    Next

Now you can assign tempArr back to the original or what ever you need done with it as in...

TextBox1.Lines = tempArr (You now have a textbox void of blank lines)

I know you said you didn't want to catch an exception. But, because catching an exception is more reliable, I will go ahead and post this answer.

public static bool IsBase64(this string base64String) {
     // Credit: oybek https://stackoverflow.com/users/794764/oybek
     if (string.IsNullOrEmpty(base64String) || base64String.Length % 4 != 0
        || base64String.Contains(" ") || base64String.Contains("\t") || base64String.Contains("\r") || base64String.Contains("\n"))
        return false;

     try{
         Convert.FromBase64String(base64String);
         return true;
     }
     catch(Exception exception){
     // Handle the exception
     }
     return false;
}

Update: I've updated the condition thanks to oybek to further improve reliability.

Create the following method:

public class Logger {
    public static void log(String message) { 
      PrintWriter out = new PrintWriter(new FileWriter("output.txt", true), true);
      out.write(message);
      out.close();
    }
}

(I haven't included the proper IO handling in the above class, and it won't compile - do it yourself. Also consider configuring the file name. Note the "true" argument. This means the file will not be re-created each time you call the method)

Then instead of System.out.println(str) call Logger.log(str)

This manual approach is not preferable. Use a logging framework - slf4j, log4j, commons-logging, and many more

Using prototypes:

function Box(color) // Constructor
{
    this.color = color;
}

Box.prototype.getColor = function()
{
    return this.color;
};

Hiding "color" (somewhat resembles a private member variable):

function Box(col)
{
   var color = col;

   this.getColor = function()
   {
       return color;
   };
}

Usage:

var blueBox = new Box("blue");
alert(blueBox.getColor()); // will alert blue

var greenBox = new Box("green");
alert(greenBox.getColor()); // will alert green

note - Lepl is no longer maintained or supported.

RFC 3696 defines "best practices" for URL validation - http://www.faqs.org/rfcs/rfc3696.html

The latest release of Lepl (a Python parser library) includes an implementation of RFC 3696. You would use it something like:

from lepl.apps.rfc3696 import Email, HttpUrl

# compile the validators (do once at start of program)
valid_email = Email()
valid_http_url = HttpUrl()

# use the validators (as often as you like)
if valid_email(some_email):
    # email is ok
else:
    # email is bad
if valid_http_url(some_url):
    # url is ok
else:
    # url is bad

Although the validators are defined in Lepl, which is a recursive descent parser, they are largely compiled internally to regular expressions. That combines the best of both worlds - a (relatively) easy to read definition that can be checked against RFC 3696 and an efficient implementation. There's a post on my blog showing how this simplifies the parser - http://www.acooke.org/cute/LEPLOptimi0.html

Lepl is available at http://www.acooke.org/lepl and the RFC 3696 module is documented at http://www.acooke.org/lepl/rfc3696.html

This is completely new in this release, so may contain bugs. Please contact me if you have any problems and I will fix them ASAP. Thanks.

You are using a Declarative Pipeline which requires a script-step to execute Groovy code. This is a huge difference compared to the Scripted Pipeline where this is not necessary.

The official documentation says the following:

The script step takes a block of Scripted Pipeline and executes that in the Declarative Pipeline.

pipeline {
   agent none
   stages {
       stage("first") {
           script {
               def foo = "foo" 
               sh "echo ${foo}"
           }
       }
   }
}

You're reading the entire file into memory (line = u.readlines()) which will fail of course if the file is too large (and you say that some are up to 20 GB), so that's your problem right there.

Better iterate over each line:

for current_line in u:
    do_something_with(current_line)

is the recommended approach.

Later in your script, you're doing some very strange things like first counting all the items in a list, then constructing a for loop over the range of that count. Why not iterate over the list directly? What is the purpose of your script? I have the impression that this could be done much easier.

This is one of the advantages of high-level languages like Python (as opposed to C where you do have to do these housekeeping tasks yourself): Allow Python to handle iteration for you, and only collect in memory what you actually need to have in memory at any given time.

Also, as it seems that you're processing TSV files (tabulator-separated values), you should take a look at the csv module which will handle all the splitting, removing of \ns etc. for you.

I'm not sure what you're trying to do here:

npm install alone in your home directory shouldn't do much -- it's not the root of a node app, so there's nothing to install, since there's no package.json.

There are two possible solutions:

1) cd to a node app and run npm install there. OR

2) if you're trying to install something as a command to use in the shell (You don't have a node application), npm install -g packagename. -g flag tells it to install in global namespace.

Use $dec = $null

From the documentation:

$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.

PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

Just set the value of cookie to false in order to unset it,

setcookie('cookiename', false);

PS:- That's the easiest way to do it.

There is a quick method to set the syntax: Ctrl+Shift+P,then type in the input box

ss + (which type you want set)

eg: ss html +Enter

and ss means "set syntax"

it is really quicker than check in the menu's checkbox.

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

The RSACryptoServiceProvider(CspParameters) constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.

It sounds as if you are not interested in having the key stored on the machine.

So use the RSACryptoServiceProvider(Int32) constructor:

public static void AssignNewKey(){
    RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

EDIT:

Alternatively try setting the PersistKeyInCsp to false:

public static void AssignNewKey(){
    const int PROVIDER_RSA_FULL = 1;
    const string CONTAINER_NAME = "KeyContainer";
    CspParameters cspParams;
    cspParams = new CspParameters(PROVIDER_RSA_FULL);
    cspParams.KeyContainerName = CONTAINER_NAME;
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
    rsa = new RSACryptoServiceProvider(cspParams);

    rsa.PersistKeyInCsp = false;

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

1. Creation and initialization

   Object[] yourArray = new Object[ARRAY_LENGTH];
   

2. Write access

   yourArray[i]= someArrayList;
   

   to access elements of internal ArrayList:

   ((ArrayList<YourType>) yourArray[i]).add(elementOfYourType); //or other method
   

3. Read access

   to read array element i as an ArrayList use type casting:

   someElement= (ArrayList<YourType>) yourArray[i];
   

   for array element i: to read ArrayList element at index j

   arrayListElement= ((ArrayList<YourType>) yourArray[i]).get(j);
   

In XML Serializing, you can use the [XmlIgnore] attribute (System.Xml.Serialization.XmlIgnoreAttribute) to ignore a property when serializing a class.

This may be of use to you (Or it just may be of use to anyone who found this question when attempting to find out how to ignore a property when Serializing in XML, as I was).

Simple solution

var tx = [{"id":1},{"id":2}];
var tx1 = [{"id":3},{"id":4}];


var txHistory = tx.concat(tx1)

console.log(txHistory); 
// output
 // [{"id":1},{"id":2},{"id":3},{"id":4}];

Use the CX register to count the loops

mov cx, 3
startloop:
   cmp cx, 0
   jz endofloop
   push cx
loopy:
   Call ClrScr
   pop cx
   dec cx
   jmp startloop
endofloop:
   ; Loop ended
   ; Do what ever you have to do here

This simply loops around 3 times calling ClrScr, pushing the CX register onto the stack, comparing to 0, jumping if ZeroFlag is set then jump to endofloop. Notice how the contents of CX is pushed/popped on/off the stack to maintain the flow of the loop.

Java includes a scripting language extension package starting with version 6.

See the Rhino project documentation for embedding a JavaScript interpreter in Java.

[Edit]

Here is a small example of how you can expose Java objects to your interpreted script:

public class JS {
  public static void main(String args[]) throws Exception {
    ScriptEngine js = new ScriptEngineManager().getEngineByName("javascript");
    Bindings bindings = js.getBindings(ScriptContext.ENGINE_SCOPE);
    bindings.put("stdout", System.out);
    js.eval("stdout.println(Math.cos(Math.PI));");
    // Prints "-1.0" to the standard output stream.
  }
}

a=[1,2,3]
b=[str(x) for x in a]
print b

above method is the easiest and most general way to convert list into string. another short method is-

a=[1,2,3]
b=map(str,a)
print b

This is guesswork, but you may need to supply some or all of the floating point related switches for the link stage as well.

Ok so if you need 72dp, couldn't you just add the difference in padding in the xml file? This way you keep Androids default Inset/Padding that they want us to use.

So: 72-16=56

Therefor: add 56dp padding to put yourself at an indent/margin total of 72dp.

Or you could just change the values in the Dimen.xml files. that's what I am doing now. It changes everything, the entire layout, including the ToolBar when implemented in the new proper Android way.

Dimen Resource File

The link I added shows the Dimen values at 2dp because I changed it but it was default set at 16dp. Just FYI...

Creating an sqlite connection to a file on disk is left as an exercise for the reader ... but there is now a two-liner made possible by the pandas library

df = pandas.read_csv(csvfile)
df.to_sql(table_name, conn, if_exists='append', index=False)

Here's an example that shows how table(.) (or, more closely matching your desired output, data.frame(table(.)) does what it sounds like you are asking for.

Note also how to share reproducible sample data in a way that others can copy and paste into their session.

Here's the (reproducible) sample data:

mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L), 
                       MONTH.YEAR = c("JAN. 2012", "JAN. 2012", 
                                      "FEB. 2012", "FEB. 2012", 
                                      "MAR. 2012"), 
                       VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)), 
                  .Names = c("ID", "MONTH.YEAR", "VALUE"), 
                  class = "data.frame", row.names = c(NA, -5L))

mydf
#    ID MONTH.YEAR VALUE
# 1 110  JAN. 2012  1000
# 2 111  JAN. 2012  2000
# 3 121  FEB. 2012  3000
# 4 131  FEB. 2012  4000
# 5 141  MAR. 2012  5000

Here's the calculation of the number of rows per group, in two output display formats:

table(mydf$MONTH.YEAR)
# 
# FEB. 2012 JAN. 2012 MAR. 2012 
#         2         2         1

data.frame(table(mydf$MONTH.YEAR))
#        Var1 Freq
# 1 FEB. 2012    2
# 2 JAN. 2012    2
# 3 MAR. 2012    1

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

Do it faster.

Low level calls need to be very fast so I thought it was worth some research. I tried a few methods (with various string lengths, extension lengths, multiple runs each), here's some reasonable ones:

function method1($s) {return preg_replace("/.*\./","",$s);} // edge case problem
function method2($s) {preg_match("/\.([^\.]+)$/",$s,$a);return $a[1];}
function method3($s) {$n = strrpos($s,"."); if($n===false) return "";return substr($s,$n+1);}
function method4($s) {$a = explode(".",$s);$n = count($a); if($n==1) return "";return $a[$n-1];}
function method5($s) {return pathinfo($s, PATHINFO_EXTENSION);}

Results were not very surprising. Poor pathinfo is (by far!) the slowest; even with the PATHINFO_EXTENSION option, it looks like he's trying to parse the whole thing and then drop all unnecessary parts. On the other hand, the built-in strrpos function is invented almost exactly for this job, takes no detours, so no wonder it performs a lot better than other applicants:

Original filename was: something.that.contains.dots.txt
Running 50 passes with 10000 iterations each
Minimum of measured times per pass:

    Method 1:   312.6 mike  (response: txt) // preg_replace
    Method 2:   472.9 mike  (response: txt) // preg_match
    Method 3:   167.8 mike  (response: txt) // strrpos
    Method 4:   340.3 mike  (response: txt) // explode
    Method 5:  2311.1 mike  (response: txt) // pathinfo  <--------- poor fella

NOTE: the first method has a side effect: it returns the whole name when there's no extension. Surely it would make no sense to measure it with an additional strpos to avoid this behaviour.

Conclusion

This seems to be the Way of the Samurai:

function fileExtension($s) {
    $n = strrpos($s,".");
    return ($n===false) ? "" : substr($s,$n+1);
}

Some test cases

File name            fileExtension()
----------------------------------------
file                 ""
file.                ""
file.txt             "txt"
file.txt.bin         "bin"
file.txt.whatever    "whatever"
.htaccess            "htaccess"

(The last one is a bit special; it could be only an extension, or an empty extension with the pure name being ".htaccess", I'm not sure if there's a rule for that. So I guess you can go with both, as long as you know what you're doing.)

Simple functionality is not included in Swift, expected because it's included in other languages, can often be quickly coded for reuse. Pro tip for programmers to create a bag of tricks file that contains all this reuse code.

So from my bag of tricks we first need string multiplication for use in indentation.

@inlinable func * (string: String, scalar: Int) -> String {
    let array = [String](repeating: string, count: scalar)
    return array.joined(separator: "")
}

and then the code to add commas.

extension Int {
    @inlinable var withCommas:String {
        var i = self
        var retValue:[String] = []
        while i >= 1000 {
            retValue.append(String(format:"%03d",i%1000))
            i /= 1000
        }
        retValue.append("\(i)")
        return retValue.reversed().joined(separator: ",")
    }

    @inlinable func withCommas(_ count:Int = 0) -> String {
        let retValue = self.withCommas
        let indentation = count - retValue.count
        let indent:String = indentation >= 0 ? " " * indentation : ""

        return indent + retValue
    }
}

I just wrote this last function so I could get the columns to line up.

The @inlinable is great because it takes small functions and reduces their functionality so they run faster.

You can use either the variable version or, to get a fixed column, use the function version. Lengths set less than the needed columns will just expand the field.

Now you have something that is pure Swift and does not rely on some old objective C routine for NSString.

This formula does not require a column letter reference ("A", "B", etc.). It returns the value of the cell one row above in the same column.

=INDIRECT(ADDRESS(ROW()-1,COLUMN()))

If you have cloned your project from git or somewhere then first, you should type npm install.

Try to configure the setting of your projects, it is usually due to x86/x64 architecture problems:

Go and set your choice as shown:

I got same error and I solved it.

delete package-lock.json file and node_modules folder then npm install

This is how I do it.

#To update your local.
git fetch --all

this will fetch everything from the remote, so when you check difference, it will compare the difference with the remote branch.

#to list all branches
git branch -a

the above command will display all the branches.

#to go to the branch you want to check difference
git checkout <branch_name>
#to check on which branch you are in, use
git branch
    (or)
git status

Now, you can check difference as follows.

git diff origin/<branch_name>

this will compare your local branch with the remote branch

You can make use of MBProgressHUD project.

Use HUD mode MBProgressHUDModeText for toast-like behaviour,

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];

// Configure for text only and offset down
hud.mode = MBProgressHUDModeText;
hud.label.text = @"Some message...";
hud.margin = 10.f;
hud.yOffset = 150.f;
hud.removeFromSuperViewOnHide = YES;

[hud hideAnimated:YES afterDelay:3];

The IFRAME element may be a security risk if your site is embedded inside an IFRAME on hostile site. Google "clickjacking" for more details. Note that it does not matter if you use <iframe> or not. The only real protection from this attack is to add HTTP header X-Frame-Options: DENY and hope that the browser knows its job.

In addition, IFRAME element may be a security risk if any page on your site contains an XSS vulnerability which can be exploited. In that case the attacker can expand the XSS attack to any page within the same domain that can be persuaded to load within an <iframe> on the page with XSS vulnerability. This is because content from the same origin (same domain) is allowed to access the parent content DOM (practically execute JavaScript in the "host" document). The only real protection methods from this attack is to add HTTP header X-Frame-Options: DENY and/or always correctly encode all user submitted data (that is, never have an XSS vulnerability on your site - easier said than done).

That's the technical side of the issue. In addition, there's the issue of user interface. If you teach your users to trust that URL bar is supposed to not change when they click links (e.g. your site uses a big iframe with all the actual content), then the users will not notice anything in the future either in case of actual security vulnerability. For example, you could have an XSS vulnerability within your site that allows the attacker to load content from hostile source within your iframe. Nobody could tell the difference because the URL bar still looks identical to previous behavior (never changes) and the content "looks" valid even though it's from hostile domain requesting user credentials.

If somebody claims that using an <iframe> element on your site is dangerous and causes a security risk, he does not understand what <iframe> element does, or he is speaking about possibility of <iframe> related vulnerabilities in browsers. Security of <iframe src="..."> tag is equal to <img src="..." or <a href="..."> as long there are no vulnerabilities in the browser. And if there's a suitable vulnerability, it might be possible to trigger it even without using <iframe>, <img> or <a> element, so it's not worth considering for this issue.

However, be warned that content from <iframe> can initiate top level navigation by default. That is, content within the <iframe> is allowed to automatically open a link over current page location (the new location will be visible in the address bar). The only way to avoid that is to add sandbox attribute without value allow-top-navigation. For example, <iframe sandbox="allow-forms allow-scripts" ...>. Unfortunately, sandbox also disables all plugins, always. For example, Youtube content cannot be sandboxed because Flash player is still required to view all Youtube content. No browser supports using plugins and disallowing top level navigation at the same time.

Note that X-Frame-Options: DENY also protects from rendering performance side-channel attack that can read content cross-origin (also known as "Pixel perfect Timing Attacks").

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

use this:

this.permissionChanged = function (obj, event) {

    if (event.type != "load") {

    } 
}

cat /etc/*release

It's universal for almost any major distribution.

To find out the limits on your system:

#include <iostream>
#include <limits>
int main(int, char **) {
  std::cout
    << static_cast< int >(std::numeric_limits< char >::max()) << "\n"
    << static_cast< int >(std::numeric_limits< unsigned char >::max()) << "\n"
    << std::numeric_limits< short >::max() << "\n"
    << std::numeric_limits< unsigned short >::max() << "\n"
    << std::numeric_limits< int >::max() << "\n"
    << std::numeric_limits< unsigned int >::max() << "\n"
    << std::numeric_limits< long >::max() << "\n"
    << std::numeric_limits< unsigned long >::max() << "\n"
    << std::numeric_limits< long long >::max() << "\n"
    << std::numeric_limits< unsigned long long >::max() << "\n";
}

Note that long long is only legal in C99 and in C++11.

Try the following configuration:

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false

log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false

Then configure the loggers in the Java code accordingly:

static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");

Do you want output to go to stdout? If not, change the first line of log4j.properties to:

log4j.rootLogger=OFF

and get rid of the stdout lines.

The examples above use a 'K' an uppercase k used to represent kilo or 1000. According to wiki, kilo or 1000's should be represented in lower case. So, rather than £300K, use £300k or in a code example :-

[>=1000]£#,##0,"k";[red][<=-1000]-£#,##0,"k";0

This example reads all objects from a stream of objects, it is assumed that you need CustomObjects instead of a Map:

        ObjectMapper mapper = new ObjectMapper();
        JsonParser parser = mapper.getFactory().createParser( source );
        if(parser.nextToken() != JsonToken.START_ARRAY) {
          throw new IllegalStateException("Expected an array");
        }
        while(parser.nextToken() == JsonToken.START_OBJECT) {
          // read everything from this START_OBJECT to the matching END_OBJECT
          // and return it as a tree model ObjectNode
          ObjectNode node = mapper.readTree(parser);
          CustomObject custom = mapper.convertValue( node, CustomObject.class );
           // do whatever you need to do with this object
          System.out.println( "" + custom );
        }
        parser.close();

If you're using version 3.x of Bootstrap, the correct way to do this now is:

$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
})

Scroll down to the events section to learn more.

http://getbootstrap.com/javascript/#modals-usage

This appears to remain unchanged for whenever version 4 releases (http://v4-alpha.getbootstrap.com/components/modal/#events), but if it does I'll be sure to update this post with the relevant information.

JavaScript:

// Set the end and start times
var start = (new Date).getTime(), end, FPS;
  /* ...
   * the loop/block your want to watch
   * ...
   */
end = (new Date).getTime();
// since the times are by millisecond, use 1000 (1000ms = 1s)
// then multiply the result by (MaxFPS / 1000)
// FPS = (1000 - (end - start)) * (MaxFPS / 1000)
FPS = Math.round((1000 - (end - start)) * (60 / 1000));

if you are getting id from url try

$id = (isset($_GET['id']) ? $_GET['id'] : '');

if getting from form you need to use POST method cause your form has method="post"

 $id = (isset($_POST['id']) ? $_POST['id'] : '');

For php notices use isset() or empty() to check values exist or not or initialize variable first with blank or a value

$id= '';

That's a fun one. If you know ahead of time the height of the container of the text, you can use line-height equal to that height, and it should center the text vertically.

You can use py2exe as already answered and use Cython to convert your key .py files in .pyc, C compiled files, like .dll in Windows and .so on Linux.

It is much harder to revert than common .pyo and .pyc files (and also gain in performance!).

In my programs, by convention, this is what the pre-existing $REPLY variable is for, which read uses for that exact purpose.

function getSomeString {
  REPLY="tadaa"
}

getSomeString
echo $REPLY

This echoes

tadaa

But to avoid conflicts, any other global variable will do.

declare result

function getSomeString {
  result="tadaa"
}

getSomeString
echo $result

If that isn’t enough, I recommend Markarian451’s solution.

In general, you use the # syntax:

{{#a_boolean}}
  I only show up if the boolean was true.
{{/a_boolean}}

The goal is to move as much logic as possible out of the template (which makes sense).

Make sure R.layout.themechanger has no background color because by default the dialog has a default background color.

You also need to add dialog.getWindow().setBackgroundDrawable(newColorDrawable(Color.TRANSPARENT));

And finally

<style name="TransparentDialog">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
</style>

Please note that CSS3 viewport units (vh,vw) wouldn't play well on iOS When you scroll the page, viewport size is somehow recalculated and your size of element which uses viewport units also increases. So, actually some javascript is required.

In your php.ini file check for display_errors. If it is off, then make it on as below:

display_errors = On

It should display warnings/notices/errors .

Please read this

http://www.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting

The command should be the following script:

ilmerge myExe.exe Dll1.dll /target:winexe /targetplatform:"v4,c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\" /out:merged.exe /out:merged.exe

If you are using c# 3.0 (or above) you can use extenders

git branch -m old_branch_name new_branch_name

The above command will change your branch name, but you have to be very careful using the renamed branch, because it will still refer to the old upstream branch associated with it, if any.

If you want to push some changes into master after your local branch is renamed into new_branch_name (example name):

git push origin new_branch_name:master (now changes will go to master branch but your local branch name is new_branch_name)

For more details, see "How to rename your local branch name in Git."

I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.

The correct approach is to use a single timer. Using setInterval, you can achieve what you want as follows:

window.onload = function start() {
    slide();
}
function slide() {
    var num = 0, style = document.getElementById('container').style;
    window.setInterval(function () {
        // increase by num 1, reset to 0 at 4
        num = (num + 1) % 4;

        // -600 * 1 = -600, -600 * 2 = -1200, etc 
        style.marginLeft = (-600 * num) + "px"; 
    }, 3000); // repeat forever, polling every 3 seconds
}

I use this simple utility function:

rows = function(tab) lapply(
  seq_len(nrow(tab)),
  function(i) unclass(tab[i,,drop=F])
)

Or a faster, less clear form:

rows = function(x) lapply(seq_len(nrow(x)), function(i) lapply(x,"[",i))

This function just splits a data.frame to a list of rows. Then you can make a normal "for" over this list:

tab = data.frame(x = 1:3, y=2:4, z=3:5)
for (A in rows(tab)) {
    print(A$x + A$y * A$z)
}        

Your code from the question will work with a minimal modification:

for (well in rows(dataFrame)) {
  wellName <- well$name    # string like "H1"
  plateName <- well$plate  # string like "plate67"
  wellID <- getWellID(wellName, plateName)
  cat(paste(wellID, well$value1, well$value2, sep=","), file=outputFile)
}

You can't: DataFrame columns are Series, by definition. That said, if you make the dtype (the type of all the elements) datetime-like, then you can access the quantities you want via the .dt accessor (docs):

>>> df["TimeReviewed"] = pd.to_datetime(df["TimeReviewed"])
>>> df["TimeReviewed"]
205  76032930   2015-01-24 00:05:27.513000
232  76032930   2015-01-24 00:06:46.703000
233  76032930   2015-01-24 00:06:56.707000
413  76032930   2015-01-24 00:14:24.957000
565  76032930   2015-01-24 00:23:07.220000
Name: TimeReviewed, dtype: datetime64[ns]
>>> df["TimeReviewed"].dt
<pandas.tseries.common.DatetimeProperties object at 0xb10da60c>
>>> df["TimeReviewed"].dt.year
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
dtype: int64
>>> df["TimeReviewed"].dt.month
205  76032930    1
232  76032930    1
233  76032930    1
413  76032930    1
565  76032930    1
dtype: int64
>>> df["TimeReviewed"].dt.minute
205  76032930     5
232  76032930     6
233  76032930     6
413  76032930    14
565  76032930    23
dtype: int64

If you're stuck using an older version of pandas, you can always access the various elements manually (again, after converting it to a datetime-dtyped Series). It'll be slower, but sometimes that isn't an issue:

>>> df["TimeReviewed"].apply(lambda x: x.year)
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
Name: TimeReviewed, dtype: int64

<div>

For ViewPager2,

viewPager.registerOnPageChangeCallback(object : ViewPager2.OnPageChangeCallback() {
  override fun onPageSelected(position: Int) {
    super.onPageSelected(position)

})

where OnPageChangeCallback is a static class with three methods:

onPageScrolled(int position, float positionOffset, @Px int positionOffsetPixels),
onPageSelected(int position), 
onPageScrollStateChanged(@ScrollState int state)

If you grep the command that you are looking for with a pipe from ps aux, it will wrap the text automatically. I used a lot of the other answers on here, but sometimes if you are looking for something specific, it is nice to just use grep and you know that it will wrap lines.

For instance ps aux | grep ffmpeg .

Include jquery.js and if it is included, load it before any other JavaScript code.

%Lf (note the capital L) is the format specifier for long doubles.

For plain doubles, either %e, %E, %f, %g or %G will do.

You can use this, just think Job is the name of the model to which you are adding index cader_id:

class AddCaderIdToJob < ActiveRecord::Migration[5.2]
  def change
    change_table :jobs do |t|
      t.integer :cader_id
      t.index :cader_id
    end
  end
end

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
   percentage binned
0       46.50      5
1       44.20      5
2      100.00      6
3       42.12      5

Or numpy.searchsorted:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
   percentage  binned
0       46.50       5
1       44.20       5
2      100.00       6
3       42.12       5

...and then value_counts or groupby and aggregate size:

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

As others suggested, you can use String.compareTo(String).

But if you are sorting a list of Strings and you need a Comparator, you don't have to implement it, you can use Comparator.naturalOrder() or Comparator.reverseOrder().

There is another option to scroll page to required element if element has "id" attribute

If you want to navigate to page and scroll down to element with @id, it can be done automatically by adding #element_id to URL...

Example

Let's say we need to navigate to Selenium Waits documentation and scroll page down to "Implicit Wait" section. We can do

driver.get('https://selenium-python.readthedocs.io/waits.html')

and add code for scrolling...OR use

driver.get('https://selenium-python.readthedocs.io/waits.html#implicit-waits')

to navigate to page AND scroll page automatically to element with id="implicit-waits" (<div class="section" id="implicit-waits">...</div>)

I know this has already been answered, but I stumbled across this question and went down the path of using format, which works, but it returns them as strings when I wanted integers.

I just realized that moment comes with date, month and year methods that return the actual integers for each method.

moment().date()
moment().month()  // jan=0, dec=11
moment().year()

The git command that would be the closest from what you are looking for would by git archive.
See backing up project which uses git: it will include in an archive all files (including submodules if you are using the git-archive-all script)

You can then use that archive anywhere, giving you back only files, no .git directory.

git archive --remote=<repository URL> | tar -t

If you need folders and files just from the first level:

git archive --remote=<repository URL> | tar -t --exclude="*/*"

To list only first-level folders of a remote repo:

git archive --remote=<repository URL> | tar -t --exclude="*/*" | grep "/"

Note: that does not work for GitHub (not supported)

So you would need to clone (shallow to quicken the clone step), and then archive locally:

git clone --depth=1 [email protected]:xxx/yyy.git
cd yyy
git archive --format=tar aTag -o aTag.tar

Another option would be to do a shallow clone (as mentioned below), but locating the .git folder elsewhere.

git --git-dir=/path/to/another/folder.git clone --depth=1 /url/to/repo

The repo folder would include only the file, without .git.

Note: git --git-dir is an option of the command git, not git clone.

Update with Git 2.14.X/2.15 (Q4 2017): it will make sure to avoid adding empty folders.

"git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so.
This has been fixed.

See commit 4318094 (12 Sep 2017) by René Scharfe (``).
Suggested-by: Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 62b1cb7, 25 Sep 2017)}

archive: don't add empty directories to archives

While git doesn't track empty directories, git archive can be tricked into putting some into archives.
While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild.

As empty directories are not supported by git, they should also not be written into archives.
If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it.

Here it is in C# (lat and long in radians):

double CalculateGreatCircleDistance(double lat1, double long1, double lat2, double long2, double radius)
{
    return radius * Math.Acos(
        Math.Sin(lat1) * Math.Sin(lat2)
        + Math.Cos(lat1) * Math.Cos(lat2) * Math.Cos(long2 - long1));
}

If your lat and long are in degrees then divide by 180/PI to convert to radians.

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

The general idea is to sweep the function across. You have many options, one is apply():

R> set.seed(42)
R> M <- matrix(rnorm(40),ncol=4)
R> apply(M, 2, sd)
[1] 0.835449 1.630584 1.156058 1.115269
R> 

I will share my code:

In your given example date:

$dateValue = '2012-01-05';

It will go like this:

dateName($dateValue);



   function dateName($date) {

        $result = "";

        $convert_date = strtotime($date);
        $month = date('F',$convert_date);
        $year = date('Y',$convert_date);
        $name_day = date('l',$convert_date);
        $day = date('j',$convert_date);


        $result = $month . " " . $day . ", " . $year . " - " . $name_day;

        return $result;
    }

and will return a value: January 5, 2012 - Thursday

I couldn't find a simple example about the differences between ES6 and ES5, so I made one. Both code samples create exactly the same object. But the ES5 example also works in older browsers (like IE11), wheres the ES6 example doesn't.

ES6

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

matrix[a] = {[b]: {[c]: d}};

ES5

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

function addObj(obj, key, value) {
  obj[key] = value;
  return obj;
}

matrix[a] = addObj({}, b, addObj({}, c, d));

vim /etc/default/locale

add to it:

LC_ALL="en_US.UTF-8"

Solution:

CFLAGS=-Wno-error ./configure

Way to clean out any old versions of gems.

sudo gem cleanup

If you just want to see a list of what would be removed you can use:

sudo gem cleanup -d

You can also cleanup just a specific gem by specifying its name:

sudo gem cleanup gemname

for remove specific version like 1.1.9 only

gem uninstall gemname --version 1.1.9

If you still facing some exception to install gem, like:

invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem

the, you can remove it from cache:

rm /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem

For more detail:

http://blog.grepruby.com/2015/04/way-to-clean-up-gem-or-remove-old.html

You can launch any command line program using the Process class, and set the StandardOutput property of the Process instance with a stream reader you create (either based on a string or a memory location). After the process completes, you can then do whatever diff you need to on that stream.

For Java < 7 you can use if-else along with Exception:

try {
    // common logic to handle both exceptions
} catch (Exception ex) {
    if (ex instanceof Exception1 || ex instanceof Exception2) {

    }
    else {
        throw ex;
        // or if you don't want to have to declare Exception use
        // throw new RuntimeException(ex);
    }
}

Edited and replaced Throwable with Exception.

Tried the above but the option to amend the permission was not available for the htdocs folder,

My solution was:

1. Open applications folder
2. Locate XAMPP folder
3. Right click, get info (as described above)
4. In pop-up window locate the 'sharing & permission' section
5. Click the 'locked' padlock symbol
6. Enter admin password
7. Change 'Everyone' permissions to read & write
8. In the get info window still, select the 'cog' icon' drop down option at the very bottom and select 'Apply to enclosed items' this will adjust the permission across all sub-folders as well.
9. Re-lock the padlock symbol
10. Close the 'Get Info' window.

Task complete, this will now allow you to populate sub-folders within the htdocs folder as needed to populate your website(s).

if(in_array('foo',$arg) && in_array('bar',$arg)){
    //both of them are in $arg
}

if(in_array('foo',$arg) || in_array('bar',$arg)){
    //at least one of them are in $arg
}

In the "Understanding Crashes and Crash Logs" session 414 of the 2018 WWDC they show the following way using DispatchQueues with sync.

In swift 4 should be something like the following:

class ImageCache {
    private let queue = DispatchQueue(label: "sync queue")
    private var storage: [String: UIImage] = [:]
    public subscript(key: String) -> UIImage? {
        get {
          return queue.sync {
            return storage[key]
          }
        }
        set {
          queue.sync {
            storage[key] = newValue
          }
        }
    }
}

Anyway you can also make reads faster using concurrent queues with barriers. Sync and async reads are performed concurrently and writing a new value waits for previous operations to finish.

class ImageCache {
    private let queue = DispatchQueue(label: "with barriers", attributes: .concurrent)
    private var storage: [String: UIImage] = [:]

    func get(_ key: String) -> UIImage? {
        return queue.sync { [weak self] in
            guard let self = self else { return nil }
            return self.storage[key]
        }
    }

    func set(_ image: UIImage, for key: String) {
        queue.async(flags: .barrier) { [weak self] in
            guard let self = self else { return }
            self.storage[key] = image
        }
    }
}

Try the below code this will help you`

  <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="150dp">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:src="@drawable/gallery1"/>


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="#7ad7d7d7"
        android:gravity="center"
        android:text="Juneja Art Gallery"
        android:textColor="#000000"
        android:textSize="15sp"/>
</RelativeLayout>

One solution is to wrap it in a subquery

SELECT *
FROM
(
    SELECT COUNT(column1),column1 FROM table GROUP BY column1
    UNION ALL
    SELECT COUNT(column2),column2 FROM table GROUP BY column2
    UNION ALL
    SELECT COUNT(column3),column3 FROM table GROUP BY column3
) s

Use FindIndex and lambda to find and replace your values:

int j = listofelements.FindIndex(i => i.Contains(valueFieldValue.ToString())); //Finds the item index

lstString[j] = lstString[j].Replace(valueFieldValue.ToString(), value.ToString()); //Replaces the item by new value

What about this:

while ($row = mysql_fetch_array($result)) 
{
    $new_array[$row['id']]['id'] = $row['id'];
    $new_array[$row['id']]['link'] = $row['link'];
}

To retrieve link and id:

foreach($new_array as $array)
{       
   echo $array['id'].'<br />';
   echo $array['link'].'<br />';
}

You could do this in a single traversal, if you are willing to sacrifice memory. You can simply tally whether you have seen an integer or not in a hash/associative array. If you have already seen a number, remove it as you go, or better yet, move numbers you have not seen into a new array, avoiding any shifting in the original array.

In Perl:

foreach $i (@myary) {
    if(!defined $seen{$i}) {
        $seen{$i} = 1;
        push @newary, $i;
    }
}

You Need to take same height and width

and simply use the border-radius:360px;

Use the low-level $.ajax() call:

$.ajax({
  url: "/yourservlet",
  data: { },
  complete: function(xmlHttp) {
    // xmlHttp is a XMLHttpRquest object
    alert(xmlHttp.status);
  }
});

Try this for a redirect:

if (xmlHttp.code != 200) {
  top.location.href = '/some/other/page';
}

guys, I have also encountered this problem after having so much research on this issue I found 3 solutions to resolve this issue

1. Add these properties in your pom.xml; //Sorry for the formatting

<properties><java.version>1.8</java.version<maven.compiler.version>3.8.1</maven.compiler.version<maven.compiler.source>1.8</maven.compiler.source<maven.compiler.target>1.8</maven.compiler.target><java.version>11</java.version></properties>

2. Delete everything in the target byte version, you can find this in the java compiler setting of the IntelliJ

Remove everything below target byte version make it empty

3. Find the appium version you are using in the dependency. here I am using 7.3.0 find the version of the appium you are using in the dependency in pom.xml

Then write your version in the target byte version in java compiler enter image description here

ENJOY THE CODE>>>HOPE IT WORKED FOR YOU

This solution uses an Asynchronous call. It will likely work better than a synchronous solution.

var request = new XMLHttpRequest();
request.open("GET", "../../data/file.json", false);
request.send(null);
request.onreadystatechange = function() {
  if ( request.readyState === 4 && request.status === 200 ) {
    var my_JSON_object = JSON.parse(request.responseText);
    console.log(my_JSON_object);
  }
}

You can use the Positioned.fill with Align inside a Stack:

Stack(
  children: <Widget>[      
    Positioned.fill(
      child: Align(
        alignment: Alignment.centerRight,
        child: ....                
      ),
    ),
  ],
),

A fresh look at this(possibly)
in your php:

else{
      $hidemydiv = "hide";
}

And then later in your html code:

<div class='<?php echo $hidemydiv ?>' > maybe show or hide this</div>

in this way your php remains quite clean

I had some decoding issues with HtmlAgility and I didn't want to invest time investigating it.

Instead I used that utility from the Microsoft Team Foundation API:

var text = HtmlFilter.ConvertToPlainText(htmlContent);

I came up with a finally macro that can be used almost like¹ the finally keyword in Java; it makes use of std::exception_ptr and friends, lambda functions and std::promise, so it requires C++11 or above; it also makes use of the compound statement expression GCC extension, which is also supported by clang.

WARNING: an earlier version of this answer used a different implementation of the concept with many more limitations.

First, let's define a helper class.

#include <future>

template <typename Fun>
class FinallyHelper {
    template <typename T> struct TypeWrapper {};
    using Return = typename std::result_of<Fun()>::type;

public:    
    FinallyHelper(Fun body) {
        try {
            execute(TypeWrapper<Return>(), body);
        }
        catch(...) {
            m_promise.set_exception(std::current_exception());
        }
    }

    Return get() {
        return m_promise.get_future().get();
    }

private:
    template <typename T>
    void execute(T, Fun body) {
        m_promise.set_value(body());
    }

    void execute(TypeWrapper<void>, Fun body) {
        body();
    }

    std::promise<Return> m_promise;
};

template <typename Fun>
FinallyHelper<Fun> make_finally_helper(Fun body) {
    return FinallyHelper<Fun>(body);
}

Then there's the actual macro.

#define try_with_finally for(auto __finally_helper = make_finally_helper([&] { try 
#define finally });                         \
        true;                               \
        ({return __finally_helper.get();})) \
/***/

It can be used like this:

void test() {
    try_with_finally {
        raise_exception();
    }    

    catch(const my_exception1&) {
        /*...*/
    }

    catch(const my_exception2&) {
        /*...*/
    }

    finally {
        clean_it_all_up();
    }    
}

The use of std::promise makes it very easy to implement, but it probably also introduces quite a bit of unneeded overhead which could be avoided by reimplementing only the needed functionalities from std::promise.

¹ CAVEAT: there are a few things that don't work quite like the java version of finally. Off the top of my head:

1. it's not possible to break from an outer loop with the break statement from within the try and catch()'s blocks, since they live within a lambda function;
2. there must be at least one catch() block after the try: it's a C++ requirement;
3. if the function has a return value other than void but there's no return within the try and catch()'s blocks, compilation will fail because the finally macro will expand to code that will want to return a void. This could be, err, avoided by having a finally_noreturn macro of sorts.

All in all, I don't know if I'd ever use this stuff myself, but it was fun playing with it. :)

irb(main):027:0> puts ['12','34','35','231'].inspect.to_s[1..-2].gsub('"', "'")
'12', '34', '35', '231'
=> nil

I've come to the conclusion the best way to get the number of jobs on a queue is to use rabbitmqctl as has been suggested several times here. To allow any chosen user to run the command with sudo I followed the instructions here (I did skip editing the profile part as I don't mind typing in sudo before the command.)

I also grabbed jamesc's grep and cut snippet and wrapped it up in subprocess calls.

from subprocess import Popen, PIPE
p1 = Popen(["sudo", "rabbitmqctl", "list_queues", "-p", "[name of your virtula host"], stdout=PIPE)
p2 = Popen(["grep", "-e", "^celery\s"], stdin=p1.stdout, stdout=PIPE)
p3 = Popen(["cut", "-f2"], stdin=p2.stdout, stdout=PIPE)
p1.stdout.close()
p2.stdout.close()
print("number of jobs on queue: %i" % int(p3.communicate()[0]))

You can also used below code

<html>
<head>
    <style>
        .labelClass{
            float: left;
            width: 113px;
        }
    </style>
</head>
<body>
  <form action="yourclassName.jsp">
    <span class="labelClass">First name: </span><input type="text" name="fname"><br>
    <span class="labelClass">Last name: </span><input type="text" name="lname"><br>
    <input type="submit" value="Submit">
  </form>
</body>
</html>

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

If that is the entire line, it very well might be because you are missing a ; at the end of the line.

All necessary git bash commands to push and pull into Github:

git status 
git pull
git add filefullpath

git commit -m "comments for checkin file" 
git push origin branch/master
git remote -v 
git log -2 

If you want to edit a file then:

edit filename.* 

To see all branches and their commits:

git show-branch

suptitle seems the way to go, but for what it's worth, the figure has a transFigure property that you can use:

fig=figure(1)
text(0.5, 0.95, 'test', transform=fig.transFigure, horizontalalignment='center')

Use like below:

  yourFunc(input: any):Observable<string> {
var requestHeader = { headers: new HttpHeaders({ 'Content-Type': 'text/plain', 'No-Auth': 'False' })};
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<string>(this.yourBaseApi+ '/do-api', input, { headers, responseType: 'text' as 'json'  });

}

To directly answer your two subquestions: No, you cannot do this with Ajax, nor can you calculate it with PHP.

What I have done in the past is use a trigger from the iframe'd page in window.onload (NOT domready, as it can take a while for images to load) to pass the page's body height to the parent.

<body onload='parent.resizeIframe(document.body.scrollHeight)'>

Then the parent.resizeIframe looks like this:

function resizeIframe(newHeight)
{
    document.getElementById('blogIframe').style.height = parseInt(newHeight,10) + 10 + 'px';
}

Et voila, you have a robust resizer that triggers once the page is fully rendered with no nasty contentdocument vs contentWindow fiddling :)

Sure, now people will see your iframe at default height first, but this can be easily handled by hiding your iframe at first and just showing a 'loading' image. Then, when the resizeIframe function kicks in, put two extra lines in there that will hide the loading image, and show the iframe for that faux Ajax look.

Of course, this only works from the same domain, so you may want to have a proxy PHP script to embed this stuff, and once you go there, you might as well just embed your blog's RSS feed directly into your site with PHP.

All the steps you have performed are correct, except one step, instead creating one separate variable, try below steps.

1. Search for python.exe file, find the parent folder.
2. Copy the folder path like on which python installation files resides
3. Now go to the control panel-system-advanced settings-environment variables
4. Find Path variable paste the copied folder path here and add ;
5. Now all set for the execution goto cmd type python you must see the version details

Do one thing, get the commit's SHA no. such as 87c9808 and then,

1. move yourself ,that is your head to the specified commit (by doing git reset --hard 89cef43//mention your number here )
2. Next do some changes in a random file , so that the git will ask you to commit that locally and then remotely Thus, what you need to do now is. after applying change git commit -a -m "trial commit"
3. Now push the following commit (if this has been committed locally) by git push origin master
4. Now what git will ask from you is that

error: failed to push some refs to 'https://github.com/YOURREPOSITORY/AndroidExperiments.git' hint: Updates were rejected because the tip of your current branch is behind hint: its remote counterpart. Integrate the remote changes (e.g. hint: 'git pull ...') before pushing again.**

5. Thus now what you can do is

git push --force origin master

6. And thus, i hope it works :)

You are passing the Application Context not the Activity Context with

getApplicationContext();

Wherever you are passing it pass this or ActivityName.this instead.

Since you are trying to cast the Context you pass (Application not Activity as you thought) to an Activity with

(Activity)

you get this exception because you can't cast the Application to Activity since Application is not a sub-class of Activity.

Elaborating the answer given by Michael Berry.

Dog d = (Dog)Animal; //Compiles but fails at runtime

Here you are saying to the compiler "Trust me. I know d is really referring to a Dog object" although it's not. Remember compiler is forced to trust us when we do a downcast.

The compiler only knows about the declared reference type. The JVM at runtime knows what the object really is.

So when the JVM at the runtime figures out that the Dog d is actually referring to an Animal and not a Dog object it says. Hey... you lied to the compiler and throws a big fat ClassCastException.

So if you are downcasting you should use instanceof test to avoid screwing up.

if (animal instanceof Dog) { Dog dog = (Dog) animal; }

Now a question comes to our mind. Why the hell compiler is allowing the downcast when eventually it is going to throw a java.lang.ClassCastException?

The answer is that all the compiler can do is verify that the two types are in the same inheritance tree, so depending on whatever code might have come before the downcast, it's possible that animal is of type dog.

The compiler must allow things that might possible work at runtime.

Consider the following code snipet:

public static void main(String[] args) 
{   
    Dog d = getMeAnAnimal();// ERROR: Type mismatch: cannot convert Animal to Dog
    Dog d = (Dog)getMeAnAnimal(); // Downcast works fine. No ClassCastException :)
    d.eat();

}

private static Animal getMeAnAnimal()
{
    Animal animal = new Dog();
    return animal;
}

However, if the compiler is sure that the cast would not possible work, compilation will fail. I.E. If you try to cast objects in different inheritance hierarchies

String s = (String)d; // ERROR : cannot cast for Dog to String

Unlike downcasting, upcasting works implicitly because when you upcast you are implicitly restricting the number of method you can invoke, as opposite to downcasting, which implies that later on, you might want to invoke a more specific method.

Dog d = new Dog(); Animal animal1 = d; // Works fine with no explicit cast Animal animal2 = (Animal) d; // Works fine with n explicit cast

Both of the above upcast will work fine without any exception because a Dog IS-A Animal, anithing an Animal can do, a dog can do. But it's not true vica-versa.

Well there's certainly a better implementation of the enum solution (which is generally quite nice):

public enum Error {
  DATABASE(0, "A database error has occurred."),
  DUPLICATE_USER(1, "This user already exists.");

  private final int code;
  private final String description;

  private Error(int code, String description) {
    this.code = code;
    this.description = description;
  }

  public String getDescription() {
     return description;
  }

  public int getCode() {
     return code;
  }

  @Override
  public String toString() {
    return code + ": " + description;
  }
}

You may want to override toString() to just return the description instead - not sure. Anyway, the main point is that you don't need to override separately for each error code. Also note that I've explicitly specified the code instead of using the ordinal value - this makes it easier to change the order and add/remove errors later.

Don't forget that this isn't internationalised at all - but unless your web service client sends you a locale description, you can't easily internationalise it yourself anyway. At least they'll have the error code to use for i18n at the client side...

You can find one in the WPF Toolkit, which is also available via NuGet.

This article demos how to create a textbox which can auto-suggest items at runtime based on input, in this case, disk drive folders. WPF AutoComplete Folder TextBox

Also take a look at this nice Reusable WPF Autocomplete TextBox, it was for me very usable.

import itertools

A = list(zip([1,3,5,7,9],[2,4,6,8,10]))
B = [1,3,5,7,9]+[2,4,6,8,10]
C = list(set([1,3,5,7,9] + [2,4,6,8,10]))

D = [1,3,5,7,9]
D.append([2,4,6,8,10])

E = [1,3,5,7,9]
E.extend([2,4,6,8,10])

F = []
for a in itertools.chain([1,3,5,7,9], [2,4,6,8,10]):
    F.append(a)


print ("A: " + str(A))
print ("B: " + str(B))
print ("C: " + str(C))
print ("D: " + str(D))
print ("E: " + str(E))

F: [1, 3, 5, 7, 9, 2, 4, 6, 8, 10]

There are lot of factors , first see whether server returns the result, then check between server and client.

rectify them from server side first,then check the writing condition between server and client !

server side rectify the time outs between the datalayer and server from client side rectify the time out and number of available connections !

update-alternatives is problematic in this case as it forces you to update all the elements depending on the JDK.

For this specific purpose, the package java-common contains a tool called update-java-alternatives.

It's straightforward to use it. First list the JDK installs available on your machine:

root@mylaptop:~# update-java-alternatives -l
java-1.7.0-openjdk-amd64 1071 /usr/lib/jvm/java-1.7.0-openjdk-amd64
java-1.8.0-openjdk-amd64 1069 /usr/lib/jvm/java-1.8.0-openjdk-amd64

And then pick one up:

root@mylaptop:~# update-java-alternatives -s java-1.7.0-openjdk-amd64

In doubt change your editor to make tabs and spaces visible. It is also a very good idea to have the editor resolve all tabs to 4 spaces.

Standard CSS3 rotate should work in IE9, but I believe you need to give it a vendor prefix, like so:

  -ms-transform: rotate(10deg);

It is possible that it may not work in the beta version; if not, try downloading the current preview version (preview 7), which is a later revision that the beta. I don't have the beta version to test against, so I can't confirm whether it was in that version or not. The final release version is definitely slated to support it.

I can also confirm that the IE-specific filter property has been dropped in IE9.

[Edit]
People have asked for some further documentation. As they say, this is quite limited, but I did find this page: http://css3please.com/ which is useful for testing various CSS3 features in all browsers.

But testing the rotate feature on this page in IE9 preview caused it to crash fairly spectacularly.

However I have done some independant tests using -ms-transform:rotate() in IE9 in my own test pages, and it is working fine. So my conclusion is that the feature is implemented, but has got some bugs, possibly related to setting it dynamically.

Another useful reference point for which features are implemented in which browsers is www.canIuse.com -- see http://caniuse.com/#search=rotation

[EDIT]
Reviving this old answer because I recently found out about a hack called CSS Sandpaper which is relevant to the question and may make things easier.

The hack implements support for the standard CSS transform for for old versions of IE. So now you can add the following to your CSS:

-sand-transform: rotate(10deg);

...and have it work in IE 6/7/8, without having to use the filter syntax. (of course it still uses the filter syntax behind the scenes, but this makes it a lot easier to manage because it's using similar syntax to other browsers)

As the others said, you can't. You can find good examples of HTML-php forms on the web, here's a very useful link that combines HTML with javascript for validation and php for sending the email.

Please check the full article (includes zip example) in the source: http://www.html-form-guide.com/contact-form/php-email-contact-form.html

HTML:

<form method="post" name="contact_form"
action="contact-form-handler.php">
    Your Name:
    <input type="text" name="name">
    Email Address:
    <input type="text" name="email">
    Message:
    <textarea name="message"></textarea>
    <input type="submit" value="Submit">
</form>

JS:

<script language="JavaScript">
var frmvalidator  = new Validator("contactform");
frmvalidator.addValidation("name","req","Please provide your name");
frmvalidator.addValidation("email","req","Please provide your email");
frmvalidator.addValidation("email","email",
  "Please enter a valid email address");
</script>

PHP:

<?php
$errors = '';
$myemail = '[email protected]';//<-----Put Your email address here.
if(empty($_POST['name'])  ||
   empty($_POST['email']) ||
   empty($_POST['message']))
{
    $errors .= "\n Error: all fields are required";
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['message'];
if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i",
$email_address))
{
    $errors .= "\n Error: Invalid email address";
}

if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission: $name";
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n ".
"Email: $email_address\n Message \n $message";
$headers = "From: $myemail\n";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}

In CSS you need to use a Unicode escape sequence in place of HTML Entities. This is based on the hexadecimal value of a character.

I found that the easiest way to convert symbol to their hexadecimal equivalent is, such as from ▾ (▾) to \25BE is to use the Microsoft calculator =)

Yes. Enable programmers mode, turn on the decimal system, enter 9662, then switch to hex and you'll get 25BE. Then just add a backslash \ to the beginning.

On Windows you may try this:

• right-click in the sqlplus window
• select properties ->layout
• increase screen buffer size width to 1000

Comments INSIDE tags possible

It's possible to create custom attributes that can be used for commenting/documentation purposes.

In the example below, a documentation:info attribute is defined, with an example comment value:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:documentation="documentation.mycompany.com"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/relLayoutID"
    documentation:info="This is an example comment" >

    <TextView
        documentation:purpose="Instructions label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click here to begin."
        android:id="@+id/tvMyLabel"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true"
        documentation:info="Another example comment"
        documentation:translation_notes="This control should use the fewest characters possible, as space is limited"
        />

</RelativeLayout>

Note that in this case, documentation.mycompany.com is just a definition for the new custom XML namespace (of documentation), and is thus just a unique URI string - it can be anything as long as it's unique. The documentation to the right of the xmlns: can also be anything - this works the same way that the android: XML namespace is defined and used.

Using this format, any number of attributes can be created, such as documentation:info, documentation:translation_notes etc., along with a description value, the format being the same as any XML attribute.

In summary:

• Add a xmls:my_new_namespace attribute to the root (top-level) XML element in the XML layout file. Set its value to a unique string
• Under any child XML element within the file, use the new namespace, and any word following to define comment tags that are ignored when compiled, e.g. <TextView my_new_namespace:my_new_doc_property="description" />

Consider you can't use multiple inheritance in C#, and then look at your question again.

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

As constraint has unpredictable name, you can write special script(DropConstraint) to remove it without knowing it's name (was tested at EF 6.1.3):

public override void Up()
{    
    DropConstraint();
    AlterColumn("dbo.MyTable", "Rating", c => c.Double(nullable: false));
}

private void DropConstraint()
{
    Sql(@"DECLARE @var0 nvarchar(128)
          SELECT @var0 = name
          FROM sys.default_constraints
          WHERE parent_object_id = object_id(N'dbo.MyTable')
          AND col_name(parent_object_id, parent_column_id) = 'Rating';
          IF @var0 IS NOT NULL
              EXECUTE('ALTER TABLE [dbo].[MyTable] DROP CONSTRAINT [' + @var0 + ']')");
}

public override void Down()
{            
    AlterColumn("dbo.MyTable", "Rating", c => c.Int(nullable: false));    
}

Google introduced In-app updates feature, (https://developer.android.com/guide/app-bundle/in-app-updates) it works on Lollipop+ and gives you the ability to ask the user for an update with a nice dialog (FLEXIBLE) or with mandatory full-screen message (IMMEDIATE).

Here is how Flexible update will look like:

and here is Immedtiate update flow:

You can check my answer here https://stackoverflow.com/a/56808529/5502121 to get the complete sample code of implementing both Flexible and Immediate update flows. Hope it helps!

In order for a bot to send a message, you need <client>.send() , the client is where the bot will send a message to(A channel, everywhere in the server, or a PM). Since you want the bot to PM a certain user, you can use message.author as your client. (you can replace author as mentioned user in a message or something, etc)

Hence, the answer is: message.author.send("Your message here.")

I recommend looking up the Discord.js documentation about a certain object's properties whenever you get stuck, you might find a particular function that may serve as your solution.

Try this

class piramid 
{
    public static void main(String[] args) 
    {
        //System.out.println("Hello World!");

    int max = 7; 
    int k=max/2;
    int j ; 
    printf("\n");
    printf("\n");
    printf("\n");
    printf("\n");
    for(i=k;i>0;i--){

          for(j=0;j<k+1;j++){

                if(i==j){

                       printf("*");

                }else if(j>i){
                      printf(" ");
                      printf("*");
                }else {
                      printf(" ");

                }

           }
            printf("\n");

    }

   }

}

hope it will help you

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

I had the same problem and precomputed the values for Q1, Q2, median, ymin, ymax using boxplot.stats:

# Load package and generate data
library(ggplot2)
data <- rnorm(100)

# Compute boxplot statistics
stats <- boxplot.stats(data)$stats
df <- data.frame(x="label1", ymin=stats[1], lower=stats[2], middle=stats[3], 
                 upper=stats[4], ymax=stats[5])

# Create plot
p <- ggplot(df, aes(x=x, lower=lower, upper=upper, middle=middle, ymin=ymin, 
                    ymax=ymax)) + 
    geom_boxplot(stat="identity")
p

The result is a boxplot without outliers.

Decode it with the unicode-escape codec:

>>> a="Hello\u2026"
>>> a.decode('unicode-escape')
u'Hello\u2026'
>>> print _
Hello…

This is because for a non-unicode string the \u2026 is not recognised but is instead treated as a literal series of characters (to put it more clearly, 'Hello\\u2026'). You need to decode the escapes, and the unicode-escape codec can do that for you.

Note that you can get unicode to recognise it in the same way by specifying the codec argument:

>>> unicode(a, 'unicode-escape')
u'Hello\u2026'

But the a.decode() way is nicer.

Open project.properties file and change the line with target=android-22 to the desired value.
For example:

target=android-19

If you are just trying to simulate a Form.ShowDialog call but WITHOUT blocking anything (kinda like a Simulated Dialog Form) you can try using Form.Show() and as soon as you show the simulated dialog form then immediately disable all other windows using something like...

private void DisableAllWindows()
{
foreach (Form f in Application.OpenForms)
if (f.Name != this.Name)f.Enabled = false;
else f.Focus();
}

Then when you close your "pseudo-dialog form" be sure to call....

private void EnableAllWindows()
{
foreach (Form f in Application.OpenForms) f.Enabled = true;
}

Subclass the button to store the required value, maybe create a protocol (ControlWithData or something). Set the value when you add the button to the table view cell. In your touch up event, see if the sender obeys the protocol and extract the data. I normally store a reference to the actual object that is rendered on the table view cell.

//for update

(from x in dataBase.Customers
         where x.Name == "Test"
         select x).ToList().ForEach(xx => xx.Name="New Name");

//for delete

dataBase.Customers.RemoveAll(x=>x.Name=="Name");

Something quick and dirty:

<script type='text/javascript'>
function del_tr(remtr)  
{   
    while((remtr.nodeName.toLowerCase())!='tr')
        remtr = remtr.parentNode;

    remtr.parentNode.removeChild(remtr);
}
function del_id(id)  
{   
        del_tr(document.getElementById(id));
}
</script>

if you place

<a href='' onclick='del_tr(this);return false;'>x</a>

anywhere within the row you want to delete, than its even working without any ids

Your best approach for such an example would be a list comprehension

somelist = [tup for tup in somelist if determine(tup)]

In cases where you're doing something more complex than calling a determine function, I prefer constructing a new list and simply appending to it as I go. For example

newlist = []
for tup in somelist:
    # lots of code here, possibly setting things up for calling determine
    if determine(tup):
        newlist.append(tup)
somelist = newlist

Copying the list using remove might make your code look a little cleaner, as described in one of the answers below. You should definitely not do this for extremely large lists, since this involves first copying the entire list, and also performing an O(n) remove operation for each element being removed, making this an O(n^2) algorithm.

for tup in somelist[:]:
    # lots of code here, possibly setting things up for calling determine
    if determine(tup):
        newlist.append(tup)

Maybe easy like this?

Compiled binaries of the PHP interpreter can be found at http://www.mamp.info/en/ downloads/index.html . Drop this downloaded folder into your /Applications/MAMP/bin/php! directory. Close and re-open your MAMP PRO application. Your new PHP version should now appear in the PHP drop down menu. MAMP PRO will only support PHP versions from the downloads page.

I have been struggling with how to add query string parameters to my URL. I couldn't make it work until I realized that I needed to add ? at the end of my URL, otherwise it won't work. This is very important as it will save you hours of debugging, believe me: been there...done that.

Below, is a simple API Endpoint that calls the Open Weather API and passes APPID, lat and lon as query parameters and return weather data as a JSON object. Hope this helps.

//Load the request module
var request = require('request');

//Load the query String module
var querystring = require('querystring');

// Load OpenWeather Credentials
var OpenWeatherAppId = require('../config/third-party').openWeather;

router.post('/getCurrentWeather', function (req, res) {
    var urlOpenWeatherCurrent = 'http://api.openweathermap.org/data/2.5/weather?'
    var queryObject = {
        APPID: OpenWeatherAppId.appId,
        lat: req.body.lat,
        lon: req.body.lon
    }
    console.log(queryObject)
    request({
        url:urlOpenWeatherCurrent,
        qs: queryObject
    }, function (error, response, body) {
        if (error) {
            console.log('error:', error); // Print the error if one occurred

        } else if(response && body) {
            console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
            res.json({'body': body}); // Print JSON response.
        }
    })
})  

Or if you want to use the querystring module, make the following changes

var queryObject = querystring.stringify({
    APPID: OpenWeatherAppId.appId,
    lat: req.body.lat,
    lon: req.body.lon
});

request({
   url:urlOpenWeatherCurrent + queryObject
}, function (error, response, body) {...})

This is the best solution I found so far.

in blade

@if($mentors->count() == 0)
    <td colspan="5" class="text-center">
        Nothing Found
    </td>
@endif

in controller

if ($mentors->count() == 0) {
    return "Nothing Found";
}

From CLI:

$ su - postgres 
$ psql template1
template1=# CREATE USER tester WITH PASSWORD 'test_password';
template1=# GRANT ALL PRIVILEGES ON DATABASE "test_database" to tester;
template1=# \q

PHP (as tested on localhost, it works as expected):

  $connString = 'port=5432 dbname=test_database user=tester password=test_password';
  $connHandler = pg_connect($connString);
  echo 'Connected to '.pg_dbname($connHandler);

No. It's very easy to check.

public class Catch {
    public static void main(String[] args) {
        try {
            throw new java.io.IOException();
        } catch (java.io.IOException exc) {
            System.err.println("In catch IOException: "+exc.getClass());
            throw new RuntimeException();
        } catch (Exception exc) {
            System.err.println("In catch Exception: "+exc.getClass());
        } finally {
            System.err.println("In finally");
        }
    }
}

Should print:

In catch IOException: class java.io.IOException
In finally
Exception in thread "main" java.lang.RuntimeException
        at Catch.main(Catch.java:8)

Technically that could have been a compiler bug, implementation dependent, unspecified behaviour, or something. However, the JLS is pretty well nailed down and the compilers are good enough for this sort of simple thing (generics corner case may be a different matter).

Also note, if you swap around the two catch blocks, it wont compile. The second catch would be completely unreachable.

Note the finally block always runs even if a catch block is executed (other than silly cases, such as infinite loops, attaching through the tools interface and killing the thread, rewriting bytecode, etc.).

To anyone who is still interested in this question: If: 1-decodeByteArray returns null 2-Base64.decode throws bad-base64 Exception

Here is the solution: -You should consider the value sent to you from API is Base64 Encoded and should be decoded first in order to cast it to a Bitmap object! -Take a look at your Base64 encoded String, If it starts with

data:image/jpg;base64

The Base64.decode won't be able to decode it, So it has to be removed from your encoded String:

final String encodedString = "data:image/jpg;base64, ....";                        
final String pureBase64Encoded = encodedString.substring(encodedString.indexOf(",")  + 1);

Now the pureBase64Encoded object is ready to be decoded:

final byte[] decodedBytes = Base64.decode(pureBase64Encoded, Base64.DEFAULT);

Now just simply use the line below to turn this into a Bitmap Object! :

Bitmap decodedBitmap = BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);

Or if you're using the great library Glide:

Glide.with(CaptchaFragment.this).load(decodedBytes).crossFade().fitCenter().into(mCatpchaImageView);

This should do the job! It wasted one day on this and came up to this solution!

Note: If you are still getting bad-base64 error consider other Base64.decode flags like Base64.URL_SAFE and so on

None of the current answers worked for me. On CentOS, I had to delete the .eclipse folder from home directory. Then eclipse launched just fine!

The syntax is changed for Angular 2 and above:

[ngStyle]="{'background-image': 'url(path)'}"

You can combine the check and cast into one statement:

let touch = object.anyObject() as UITouch
if let picker = touch.view as? UIPickerView {
    ...
}

Then you can use picker within the if block.

Maybe your remote repo is in the branch which you want to push. You can try to checkout another branch in your remote machine. I did this, than these error disappeared, and I pushed success to my remote repo. Notice that I use ssh to connect my own server instead of github.com.

to fix SSL issue you can also try doing this.

Download the NetworkSolutionsDVServerCA2.crt from the bitbucket server and add it to the ca-bundle.crt

ca-bundle.crt needs to be copied from the git install directory and copied to your home directory

cp -r git/mingw64/ssl/certs/ca-bundle.crt ~/

then do this. this worked for me cat NetworkSolutionsDVServerCA2.crt >> ca-bundle.crt

git config --global http.sslCAInfo ~/ca-bundle.crt

git config --global http.sslverify true

The real question is why does it generate a 500 error. If it is related to any input parameters, then I would argue that it should be handled internally and returned as a 400 series error. Generally a 400, 404 or 406 would be appropriate to reflect bad input since the general convention is that a RESTful resource is uniquely identified by the URL and a URL that cannot generate a valid response is a bad request (400) or similar.

If the error is caused by anything other than the inputs explicitly or implicitly supplied by the request, then I would say a 500 error is likely appropriate. So a failed database connection or other unpredictable error is accurately represented by a 500 series error.

Yes, that code does exactly that.

You can also use:

if (@value is null or @value = '')

Edit:

With the added information that @value is an int value, you need instead:

if (@value is null)

An int value can never contain the value ''.

^(0|[1-9][0-9]*)$

assertTrue will fail if the checked value is false, and assertFalse will do the opposite: fail if the checked value is true.

Another thing, your last assertEquals will very likely fail, as it will compare the "Book was already checked out" string with the output of m1.checkOut(b1,p2). It needs a third parameter (the second value to check for equality).

I faced the same issue. I think @Rishit answer helped me. This issue is related to 32 bit/ 64 bit version of driver. I was trying to read .xlsx files to SQL Server tables using SSIS

• My machine was pre-installed with Office 2016 64 bit on Win 10 machine along with MS Access
• I was able to read excel 97-2003 (.xls) files using ssis, but unable to connect .xlsx files
• My requirement was to read .xlsx files
• Installed AccessDatabaseEngine_X64 to read xlsx, that given me the following error:

• I uninstalled the AccessDatabaseEngine_X64 and installed AccessDatabaseEngine 32 bit, that resolved the issue

Map the array is the quickest and cleanest.

var array = $.map($('input[name="locationthemes"]:checked'), function(c){return c.value; })

will return values as an array like:

array => [2,3]

assuming castle and barn were checked and the others were not.

when you setup the java home variable try to target path till JDK instead of java. setup path like: C:\Program Files\Java\jdk1.8.0_231

if you make path like C:\Program Files\Java it will run java but it will not run maven.

If you want to run the script directly, you can:

1. Add the FolderA's path to the environment variable (PYTHONPATH).
2. Add the path to sys.path in the your script.

Then:

import module_you_wanted

Yes, it is not required and is usually omitted. It might be required for accessing variables after they have been overridden in the scope though:

Person::Person() {
    int age;
    this->age = 1;
}

Also, this:

Person::Person(int _age) {
    age = _age;
}

It is pretty bad style; if you need an initializer with the same name use this notation:

Person::Person(int age) : age(age) {}

TLS 1.2 is only supported since OpenSSL 1.0.1 (see the Major version releases section), you have to update your OpenSSL.

It is not necessary to set the CURLOPT_SSLVERSION option. The request involves a handshake which will apply the newest TLS version both server and client support. The server you request is using TLS 1.2, so your php_curl will use TLS 1.2 (by default) as well if your OpenSSL version is (or newer than) 1.0.1.

Try this: TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')

Start with:

find . -name '*.log.*.zip' -a -mtime +1

You may not need a regex, try:

 find . -name '*.log.*-*-*.zip' -a -mtime +1

You will want the +1 in order to match 1, 2, 3 ...

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()):

entryList.forEach(e->e.setTempId(tempId));

List<Entry> updatedEntries = entryList.stream()
  .map(e->entityManager.update(entry, entry.getId()))
  .collect(toList());

if ($file = fopen("file.txt", "r")) {
    while(!feof($file)) {
        $line = fgets($file);
        # do same stuff with the $line
    }
    fclose($file);
}

I was facing the same issue, what i came with good solution is as below:

Try this...

$.ajax({
    type: "POST",
    url: "EditUserProfile.aspx/DeleteRecord",
    data: '{RecordId: ' + RecordId + ', UserId: ' + UId + ', UserProfileId:' + UserProfileId + ', ItemType: \'' + ItemType + '\', FileName: '\' + XmlName + '\'}',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    async: true,
    cache: false,
    success: function(msg) {
        if (msg.d != null) {
            RefreshData(ItemType, msg.d);
        }
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert("error occured during deleting");
    }
});

Please note here for string type parameter i have used (\') escape sequence character for denoting it as string value.

Sub SelectAllCellsInSheet(SheetName As String)
    lastCol = Sheets(SheetName).Range("a1").End(xlToRight).Column
    Lastrow = Sheets(SheetName).Cells(1, 1).End(xlDown).Row
    Sheets(SheetName).Range("A2", Sheets(SheetName).Cells(Lastrow, lastCol)).Select
End Sub

To use with ActiveSheet:

Call SelectAllCellsInSheet(ActiveSheet.Name)

The bias helps to get a better equation

Imagine the input and output like a function y = ax + b and you need to put the right line between the input(x) and output(y) to minimise the global error between each point and the line , if you keep the equation like this y = ax , you will have one parameter for adaptation only , even if you find the best a minimising the global error it will be kind of far from the wanted value

You can say the bias makes the equation more flexible to adapt to the best values

set -x is fine, but if you do something like:

set -x;
command;
set +x;

it would result in printing

+ command
+ set +x;

You can use a subshell to prevent that such as:

(set -x; command)

which would just print the command.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

Being consistent is important, but this is the question to ask yourself: "Do I have a constructor for anything else?"

Typically, I am creating models for data transfers that the class itself does nothing except work as housing for variables.

In these scenarios, I usually don't have any methods or constructors. It would feel silly to me to create a constructor for the exclusive purpose of initializing my lists, especially since I can initialize them in-line with the declaration.

So as many others have said, it depends on your usage. Keep it simple, and don't make anything extra that you don't have to.

There is a strcat() function from the ported C library that will do "C style string" concatenation for you.

BTW even though C++ has a bunch of functions to deal with C-style strings, it could be beneficial for you do try and come up with your own function that does that, something like:

char * con(const char * first, const char * second) {
    int l1 = 0, l2 = 0;
    const char * f = first, * l = second;

    // step 1 - find lengths (you can also use strlen)
    while (*f++) ++l1;
    while (*l++) ++l2;

    char *result = new char[l1 + l2];

    // then concatenate
    for (int i = 0; i < l1; i++) result[i] = first[i];
    for (int i = l1; i < l1 + l2; i++) result[i] = second[i - l1];

    // finally, "cap" result with terminating null char
    result[l1+l2] = '\0';
    return result;
}

...and then...

char s1[] = "file_name";
char *c = con(s1, ".txt");

... the result of which is file_name.txt.

You might also be tempted to write your own operator + however IIRC operator overloads with only pointers as arguments is not allowed.

Also, don't forget the result in this case is dynamically allocated, so you might want to call delete on it to avoid memory leaks, or you could modify the function to use stack allocated character array, provided of course it has sufficient length.

It should be understood that from a performance standpoint there are no differences between @temp tables and #temp tables that favor variables. They reside in the same place (tempdb) and are implemented the same way. All the differences appear in additional features. See this amazingly complete writeup: https://dba.stackexchange.com/questions/16385/whats-the-difference-between-a-temp-table-and-table-variable-in-sql-server/16386#16386

Although there are cases where a temp table can't be used such as in table or scalar functions, for most other cases prior to v2016 (where even filtered indexes can be added to a table variable) you can simply use a #temp table.

The drawback to using named indexes (or constraints) in tempdb is that the names can then clash. Not just theoretically with other procedures but often quite easily with other instances of the procedure itself which would try to put the same index on its copy of the #temp table.

To avoid name clashes, something like this usually works:

declare @cmd varchar(500)='CREATE NONCLUSTERED INDEX [ix_temp'+cast(newid() as varchar(40))+'] ON #temp (NonUniqueIndexNeeded);';
exec (@cmd);

This insures the name is always unique even between simultaneous executions of the same procedure.

No way to do that other than validate file extension with JavaScript when input path is populated by the file picker. To implement anything fancier you need to write your own component for whichever browser you want (activeX or XUL)

There's an "accept" attribute in HTML4.01 but I'm not aware of any browser supporting it - e.g. accept="image/gif,image/jpeg - so it's a neat but impractical spec

I'd use datediff, and not care about format conversions:

SELECT *
FROM   mytable
WHERE  DATEDIFF(MONTH, my_date_column, GETDATE()) <= 3

It is possible to set both labels together with axis.set function. Look for the example:

import pandas as pd
import matplotlib.pyplot as plt
values = [[1,2], [2,5]]
df2 = pd.DataFrame(values, columns=['Type A', 'Type B'], index=['Index 1','Index 2'])
ax = df2.plot(lw=2,colormap='jet',marker='.',markersize=10,title='Video streaming dropout by category')
# set labels for both axes
ax.set(xlabel='x axis', ylabel='y axis')
plt.show()

I was needed to solve absolutely the same task. I have divided visually the table using different background colors for different parts. Googling the Internet I've found this page https://support.microsoft.com/kb/2815384. Unfortunately it doesn't solve the issue because ColorIndex refers to some unpredictable value, so if some cells have nuances of one color (for example different values of brightness of the color), the suggested function counts them. The solution below is my fix:

Function CountBgColor(range As range, criteria As range) As Long
    Dim cell As range
    Dim color As Long
    color = criteria.Interior.color
    For Each cell In range
        If cell.Interior.color = color Then
            CountBgColor = CountBgColor + 1
        End If
    Next cell
End Function

Apparently, no.

Here's the options:

• Use Type.IsSubclassOf
• Use Type.IsAssignableFrom
• is and as

Type.IsSubclassOf

As you've already found out, this will not work if the two types are the same, here's a sample LINQPad program that demonstrates:

void Main()
{
    typeof(Derived).IsSubclassOf(typeof(Base)).Dump();
    typeof(Base).IsSubclassOf(typeof(Base)).Dump();
}

public class Base { }
public class Derived : Base { }

Output:

True
False

Which indicates that Derived is a subclass of Base, but that Baseis (obviously) not a subclass of itself.

Type.IsAssignableFrom

Now, this will answer your particular question, but it will also give you false positives. As Eric Lippert has pointed out in the comments, while the method will indeed return True for the two above questions, it will also return True for these, which you probably don't want:

void Main()
{
    typeof(Base).IsAssignableFrom(typeof(Derived)).Dump();
    typeof(Base).IsAssignableFrom(typeof(Base)).Dump();
    typeof(int[]).IsAssignableFrom(typeof(uint[])).Dump();
}

public class Base { }
public class Derived : Base { }

Here you get the following output:

True
True
True

The last True there would indicate, if the method only answered the question asked, that uint[] inherits from int[] or that they're the same type, which clearly is not the case.

So IsAssignableFrom is not entirely correct either.

is and as

The "problem" with is and as in the context of your question is that they will require you to operate on the objects and write one of the types directly in code, and not work with Type objects.

In other words, this won't compile:

SubClass is BaseClass
^--+---^
   |
   +-- need object reference here

nor will this:

typeof(SubClass) is typeof(BaseClass)
                    ^-------+-------^
                            |
                            +-- need type name here, not Type object

nor will this:

typeof(SubClass) is BaseClass
^------+-------^
       |
       +-- this returns a Type object, And "System.Type" does not
           inherit from BaseClass

Conclusion

While the above methods might fit your needs, the only correct answer to your question (as I see it) is that you will need an extra check:

typeof(Derived).IsSubclassOf(typeof(Base)) || typeof(Derived) == typeof(Base);

which of course makes more sense in a method:

public bool IsSameOrSubclass(Type potentialBase, Type potentialDescendant)
{
    return potentialDescendant.IsSubclassOf(potentialBase)
           || potentialDescendant == potentialBase;
}

To extend what Rahul Gupta said:

You can use Java function int random = Random.nextInt(n).
This returns a random int in the range [0, n-1].

I.e., to get the range [20, 80] use:

final int random = new Random().nextInt(61) + 20; // [0, 60] + 20 => [20, 80]

To generalize more:

final int min = 20;
final int max = 80;
final int random = new Random().nextInt((max - min) + 1) + min;

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.
