BIT should only allow 0 and 1 (and NULL, if the field is not defined as NOT NULL). TINYINT(1) allows any value that can be stored in a single byte, -128..127 or 0..255 depending on whether or not it's unsigned (the 1 shows that you intend to only use a single digit, but it does not prevent you from storing a larger value).

For versions older than 5.0.3, BIT is interpreted as TINYINT(1), so there's no difference there.

BIT has a "this is a boolean" semantic, and some apps will consider TINYINT(1) the same way (due to the way MySQL used to treat it), so apps may format the column as a check box if they check the type and decide upon a format based on that.

Default-Values are only considered for parameters NOT given to the function.

So given a function

procedure foo( bar1 IN number DEFAULT 3,
     bar2 IN number DEFAULT 5,
     bar3 IN number DEFAULT 8 );

if you call this procedure with no arguments then it will behave as if called with

foo( bar1 => 3,
     bar2 => 5,
     bar3 => 8 );

but 'NULL' is still a parameter.

foo( 4,
     bar3 => NULL );

This will then act like

foo( bar1 => 4,
     bar2 => 5,
     bar3 => Null );

( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )

one way to treat NULL the same as a default value would be to default the value to NULL

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL );

and using a variable with the desired value then

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL )
AS
     v_bar1    number := NVL( bar1, 3);
     v_bar2    number := NVL( bar2, 5);
     v_bar3    number := NVL( bar3, 8);

You can have a view with Background color as black and set alpha for the view as 0.7 or whatever as per your requirement.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/onboardingimg1">
    <View
        android:id="@+id/opacityFilter"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/black"
        android:layout_alignParentBottom="true"
        android:alpha="0.7">
    </View>


</RelativeLayout>

After some research and modifying my code as below, the script worked for me. I just added the condition:

this.router.navigateByUrl('/RefreshComponent', { skipLocationChange: true }).then(() => {
    this.router.navigate(['Your actualComponent']);
}); 

I know it's working for you now @Vantheman6 but this is what worked for me in case it's the same for someone else.

I added to my .env file the details of the mail service I am using. So make sure the following details

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=MyPassword

in the .env file are accurate.

NOTE: Don't forget to restart your server after editing the .env file so it will pick the new data that you put in there.

Clear config cache with below command:

php artisan config:cache

If you don't restart your server, the .env file will still continue to present the old mail data to the app even though you have made changes that can cause this error.

To expand on BalusC's answer, any scenario where the sender continues to write after the peer has stopped reading and closed its socket will produce this exception, as will the peer closing while it still had unread data in its own socket receive buffer. In other words, an application protocol error. For example, if you write something to the peer that the peer doesn't understand, and then it closes its socket in protest, and you then continue to write, the peer's TCP stack will issue an RST, which results in this exception and message at the sender.

This works

var Box = React.createClass({
    getInitialState: function() {
        return {
            color: 'white'
        };
    },

    changeColor: function() {
        var newColor = this.state.color == 'white' ? 'black' : 'white';
        this.setState({ color: newColor });
    },

    render: function() {
        return (
            <div>
                <div
                    className='box'
                    style={{background:this.state.color}}
                    onClick={this.changeColor}
                >
                    In here already
                </div>
            </div>
        );
    }
});

ReactDOM.render(<Box />, document.getElementById('div1'));
ReactDOM.render(<Box />, document.getElementById('div2'));
ReactDOM.render(<Box />, document.getElementById('div3'));

and in your css, delete the styles you have and put this

.box {
  width: 200px;
  height: 200px;
  border: 1px solid black;
  float: left;
}

You have to style the actual div you are calling onClick on. Give the div a className and then style it. Also remember to remove this block where you are rendering App into the dom, App is not defined

ReactDOM.render(<App />,document.getElementById('root'));

For a single item enumerable in java it would be Collections.singleton("string");

In c# this is going to be more efficient than a new List:

public class SingleEnumerator<T> : IEnumerable<T>
{
    private readonly T m_Value;

    public SingleEnumerator(T value)
    {
        m_Value = value;
    }

    public IEnumerator<T> GetEnumerator()
    {
        yield return m_Value;
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        yield return m_Value;
    }
}

but is there a simpler way using the framework?

  def idle
    <<~aid
    This is some description of what idle does.

    It does nothing actually, it's just here to show an example of multiline
    documentation. Thus said, this is something that is more common in the
    python community. That's an important point as it's good to also fit the
    expectation of your community of work. Now, if you agree with your team to
    go with a solution like this one for documenting your own base code, that's
    fine: just discuss about it with them first.

    Depending on your editor configuration, it won't be colored like a comment,
    like those starting with a "#". But as any keyword can be used for wrapping
    an heredoc, it is easy to spot anyway. One could even come with separated
    words for different puposes, so selective extraction for different types of
    documentation generation would be more practical. Depending on your editor,
    you possibly could configure it to use the same syntax highlight used for
    monoline comment when the keyword is one like aid or whatever you like.

    Also note that the squiggly-heredoc, using "~", allow to position
    the closing term with a level of indentation. That avoids to break the visual reading flow, unlike this far too long line.
    aid
  end

Note that at the moment of the post, the stackoverflow engine doesn't render syntax coloration correctly. Testing how it renders in your editor of choice is let as an exercise. ;)

wxWidgets has a very rich string API wxString

it can be done with (using the case conversion way)

int Contains(const wxString& SpecProgramName, const wxString& str)
{
  wxString SpecProgramName_ = SpecProgramName.Upper();
  wxString str_ = str.Upper();
  int found = SpecProgramName.Find(str_);
  if (wxNOT_FOUND == found)
  {
    return 0;
  }
  return 1;
}

What you have above is an object, not an array.

To make an array use [ & ] to surround your objects.

userTestStatus = [
  { "id": 0, "name": "Available" },
  { "id": 1, "name": "Ready" },
  { "id": 2, "name": "Started" }
];

Aside from that TypeScript is a superset of JavaScript so whatever is valid JavaScript will be valid TypeScript so no other changes are needed.

Feedback clarification from OP... in need of a definition for the model posted

You can use the types defined here to represent your object model:

type MyType = {
    id: number;
    name: string;
}

type MyGroupType = {
    [key:string]: MyType;
}

var obj: MyGroupType = {
    "0": { "id": 0, "name": "Available" },
    "1": { "id": 1, "name": "Ready" },
    "2": { "id": 2, "name": "Started" }
};
// or if you make it an array
var arr: MyType[] = [
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
];

The issue is how you're attempting to get the value. Things like...

if ( document.frm_new_user_request.u_isid.value == '' )

won't work. You need to find the element you want to get the value of first. It's not quite like a server side language where you can type in an object's reference name and a period to get or assign values.

document.getElementById('[id goes here]').value;

will work. Note: JavaScript is case-sensitive

I would recommend using:

var variablename = document.getElementById('[id goes here]');

or

var variablename = document.getElementById('[id goes here]').value;

Here is a working solution in windows 10 that does not include any third-party components. It works by wrapping the PowerShell script into VBScript.

Step 1: we need to change some windows features to allow VBScript to run PowerShell and to open .ps1 files with PowerShell by default.

-go to run and type "regedit". Click on ok and then allow it to run.

-paste this path "HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell" and press enter.

-now open the entry on the right and change the value to 0.

-open PowerShell as an administrator and type "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned", press enter and confirm the change with "y" and then enter.

Step 2: Now we can start wrapping our script.

-save your Powershell script as a .ps1 file.

-create a new text document and paste this script.

Dim objShell,objFSO,objFile

Set objShell=CreateObject("WScript.Shell")
Set objFSO=CreateObject("Scripting.FileSystemObject")

'enter the path for your PowerShell Script
 strPath="c:\your script path\script.ps1"

'verify file exists
 If objFSO.FileExists(strPath) Then
   'return short path name
   set objFile=objFSO.GetFile(strPath)
   strCMD="powershell -nologo -command " & Chr(34) & "&{" &_
    objFile.ShortPath & "}" & Chr(34)
   'Uncomment next line for debugging
   'WScript.Echo strCMD

  'use 0 to hide window
   objShell.Run strCMD,0

Else

  'Display error message
   WScript.Echo "Failed to find " & strPath
   WScript.Quit

End If

-now change the file path to the location of your .ps1 script and save the text document.

-Now right-click on the file and go to rename. Then change the filename extension to .vbs and press enter and then click ok.

DONE! If you now open the .vbs you should see no console window while your script is running in the background.

make sure to upvote if this worked for you!

I believe +%s is seconds since epoch. It's timezone invariant.

Not with CSS, no.

Not sure this was around when this question was asked but:

df.describe().show("columnName")

gives mean, count, stdtev stats on a column. I think it returns on all columns if you just do .show()

I would recommend checking out Otto, an EventBus tailored specifically to Android. Your Activity/UI can listen to events posted on the Bus from the Service, and decouple itself from the backend.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

I also had the error message "TypeError: cannot concatenate 'str' and 'int' objects". It turns out that I only just forgot to add str() around a variable when printing it. Here is my code:

def main():_x000D_
 rolling = True; import random_x000D_
 while rolling:_x000D_
  roll = input("ENTER = roll; Q = quit ")_x000D_
  if roll.lower() != 'q':_x000D_
   num = (random.randint(1,6))_x000D_
   print("----------------------"); print("you rolled " + str(num))_x000D_
  else:_x000D_
   rolling = False_x000D_
main()

I know, it was a stupid mistake but for beginners who are very new to python such as myself, it happens.

IIRC, the ConfigurationManager.RefreshSection requires a string parameter specifying the name of the Section to refresh :

ConfigurationManager.RefreshSection("connectionStrings");

I think that the ASP.NET application should automatically reload when the ConnectionStrings element is modified and the configuration does not need to be manually reloaded.

What I do is have a static class with the following code in my project:

    #region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
    printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        Debug.Write(mytable.Columns[i].ToString() + " | ");
    }
    Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            Debug.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        Debug.Write(Environment.NewLine);
    }
}
public static void ResponsePrintTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
    }
    HttpContext.Current.Response.Write("<BR>" + "=======" + "<BR>");
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        HttpContext.Current.Response.Write("<BR>");
    }
}

public static void printTblRow(DataSet myDataset, int RowNum)
{
    printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
    for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
    {
        Debug.Write(mytable.Columns[ccc].ToString() + " : ");
        Debug.Write(mytable.Rows[RowNum][ccc]);
        Debug.Write(Environment.NewLine);
    }
}
#endregion

I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window

I had been using Ladislav Mrnka's answer to successfully retrieve Ids when using the Entity Framework however I am posting here because I had been miss-using it (i.e. using it where it wasn't required) and thought I would post my findings here in-case people are looking to "solve" the problem I had.

Consider an Order object that has foreign key relationship with Customer. When I added a new customer and a new order at the same time I was doing something like this;

var customer = new Customer(); //no Id yet;
var order = new Order(); //requires Customer.Id to link it to customer;
context.Customers.Add(customer);
context.SaveChanges();//this generates the Id for customer
order.CustomerId = customer.Id;//finally I can set the Id

However in my case this was not required because I had a foreign key relationship between customer.Id and order.CustomerId

All I had to do was this;

var customer = new Customer(); //no Id yet;
var order = new Order{Customer = customer}; 
context.Orders.Add(order);
context.SaveChanges();//adds customer.Id to customer and the correct CustomerId to order

Now when I save the changes the id that is generated for customer is also added to order. I've no need for the additional steps

I'm aware this doesn't answer the original question but thought it might help developers who are new to EF from over-using the top-voted answer for something that may not be required.

This also means that updates complete in a single transaction, potentially avoiding orphin data (either all updates complete, or none do).

I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.

select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
    select o.orderID, o.price * o.qty as subtotal
    from product p inner join orderitem o on p.ProductID= o.productID
    where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal

I think this is what you're looking for.

List<String> columnData = new List<String>();

using(SqlConnection connection = new SqlConnection("conn_string"))
{
    connection.Open();
    string query = "SELECT Column1 FROM Table1";
    using(SqlCommand command = new SqlCommand(query, connection))
    {
        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                columnData.Add(reader.GetString(0));
            }         
        }
    }
}

Not tested, but this should work fine.

The "netstat --programs" command will give you the process information, assuming you're the root user. Then you will have to kill the "offending" process which may well start up again just to annoy you.

Depending on what you're actually trying to achieve, solutions to that problem will vary based on the processes holding those ports. For example, you may need to disable services (assuming they're unneeded) or configure them to use a different port (if you do need them but you need that port more).

Oracle stores only the fractions up to second in a DATE field.

Use TIMESTAMP instead:

SELECT  TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM    dual

, possibly casting it to a DATE then:

SELECT  CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM    dual

I had the same need as the original poster, except that my client's db schema is a nullable bit (ie, allows for True/False/NULL). Here's some code I wrote to both display Yes/No and handle potential nulls.

Code-Behind:

public string ConvertNullableBoolToYesNo(object pBool)
{
    if (pBool != null)
    {
        return (bool)pBool ? "Yes" : "No";
    }
    else
    {
        return "No";
    }
}

Front-End:

<%# ConvertNullableBoolToYesNo(Eval("YOUR_FIELD"))%>

Use:

Random r = new Random();
 int x= r.Next(10);//Max range

I personally didn't find any of these answers helpful. What worked in my case was giving the element float:none and position:relative. After that the element centered itself in the <td>.

C language leaves compiler some freedom about the location of the structural elements in the memory:

• memory holes may appear between any two components, and after the last component. It was due to the fact that certain types of objects on the target computer may be limited by the boundaries of addressing
• "memory holes" size included in the result of sizeof operator. The sizeof only doesn't include size of the flexible array, which is available in C/C++
• Some implementations of the language allow you to control the memory layout of structures through the pragma and compiler options

The C language provides some assurance to the programmer of the elements layout in the structure:

• compilers required to assign a sequence of components increasing memory addresses
• Address of the first component coincides with the start address of the structure
• unnamed bit fields may be included in the structure to the required address alignments of adjacent elements

Problems related to the elements alignment:

• Different computers line the edges of objects in different ways
• Different restrictions on the width of the bit field
• Computers differ on how to store the bytes in a word (Intel 80x86 and Motorola 68000)

How alignment works:

• The volume occupied by the structure is calculated as the size of the aligned single element of an array of such structures. The structure should end so that the first element of the next following structure does not the violate requirements of alignment

I implemented a pinch zoom for my TextView, using this tutorial. The resulting code is this:

private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;

and in onCreate():

    // Zoom handlers
    gestureDetector = new GestureDetector(new MyGestureDetector());
    gestureListener = new View.OnTouchListener() {

        // We can be in one of these 2 states
        static final int NONE = 0;
        static final int ZOOM = 1;
        int mode = NONE;

        static final int MIN_FONT_SIZE = 10;
        static final int MAX_FONT_SIZE = 50;

        float oldDist = 1f;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            TextView textView = (TextView) findViewById(R.id.text);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_POINTER_DOWN:
                    oldDist = spacing(event);
                    Log.d(TAG, "oldDist=" + oldDist);
                    if (oldDist > 10f) {
                       mode = ZOOM;
                       Log.d(TAG, "mode=ZOOM" );
                    }
                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    mode = NONE;
                    break;
                case MotionEvent.ACTION_MOVE:
                    if (mode == ZOOM) {
                        float newDist = spacing(event);
                        // If you want to tweak font scaling, this is the place to go.
                        if (newDist > 10f) {
                            float scale = newDist / oldDist;

                            if (scale > 1) {
                                scale = 1.1f;
                            } else if (scale < 1) {
                                scale = 0.95f;
                            }

                            float currentSize = textView.getTextSize() * scale;
                            if ((currentSize < MAX_FONT_SIZE && currentSize > MIN_FONT_SIZE)
                                    ||(currentSize >= MAX_FONT_SIZE && scale < 1)
                                    || (currentSize <= MIN_FONT_SIZE && scale > 1)) {
                                textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, currentSize);
                            }
                        }
                    }
                    break;
                }
            return false;
        }

Magic constants 1.1 and 0.95 were chosen empirically (using scale variable for this purpose made my TextView behave kind of weird).

Others have mentioned the architecture differences (little - big endian).

I read the problem that since the memory for the variables is shared, then by writing to one, the others change and, depending on their type, the value could be meaningless.

eg. union{ float f; int i; } x;

Writing to x.i would be meaningless if you then read from x.f - unless that is what you intended in order to look at the sign, exponent or mantissa components of the float.

I think there is also an issue of alignment: If some variables must be word aligned then you might not get the expected result.

eg. union{ char c[4]; int i; } x;

If, hypothetically, on some machine a char had to be word aligned then c[0] and c[1] would share storage with i but not c[2] and c[3].

I had this problem too and couldn't solve it without using VBA.

In my case I had a table with numbers that I wanted to be formatted and a corresponding table next to it with the desired formatting values.

i.e. While column F contains the values I want to format, the desired formatting for each cell is captured in column Z, expressed as "RED", "AMBER" or "GREEN."

Quick solution below. Manually select the range to which to apply the conditional formatting and then run the macro.

   Sub ConditionalFormatting()
For Each Cell In Selection.Cells
With Cell
    'clean
    .FormatConditions.Delete

    'green rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""GREEN"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -11489280
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False

    'amber rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""AMBER"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .ThemeColor = xlThemeColorAccent6
        .TintAndShade = -0.249946592608417
    End With
    .FormatConditions(1).StopIfTrue = False

    'red rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""RED"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -16776961
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False
End With

Next Cell

End Sub

Don't use regexes, use BeautifulSoup. That, or be so crufty as to spawn it out to, say, w3m/lynx and pull back in what w3m/lynx renders. First is more elegant probably, second just worked a heck of a lot faster on some unoptimized code I wrote a while back.

Yes, it is case-sensitive. You can do a case-insensitive indexOf by converting your String and the String parameter both to upper-case before searching.

String str = "Hello world";
String search = "hello";
str.toUpperCase().indexOf(search.toUpperCase());

Note that toUpperCase may not work in some circumstances. For instance this:

String str = "Feldbergstraße 23, Mainz";
String find = "mainz";
int idxU = str.toUpperCase().indexOf (find.toUpperCase ());
int idxL = str.toLowerCase().indexOf (find.toLowerCase ());

idxU will be 20, which is wrong! idxL will be 19, which is correct. What's causing the problem is tha toUpperCase() converts the "ß" character into TWO characters, "SS" and this throws the index off.

Consequently, always stick with toLowerCase()

I always initialise them as NULL.

I always use string.IsNullOrEmpty(someString) to check it's value.

Simple.

after search a long time , find a way do this . alias a git command in .gitconfig.like in android studio project,before checkout branch revert config file and then skip it ,after checkout branch use sed change config file to my local config. checkoutandmodifylocalproperties = !git update-index --no-skip-worktree local.properties && git checkout local.properties && git checkout $1 && git update-index --skip-worktree local.properties && sed -i '' 's/.*sdk.dir.*/sdk.dir=\\/Users\\/run\\/Library\\/Android\\/sdk/g' local.properties && :

Yes, and no. Despite what some other replies have said, the C compiler is required to perform conversions for sprintf(), and all other variadic functions, as follows:

• char => int
• short => int
• float => double

(and signed/unsigned variants of the above integral types)

It does this precisely because sprintf() (and the other print()-family functions) would be unusable without it. (Of course, they're pretty unusable as it is.)

But you cannot assume any other conversions, and your code will have undefined behaviour - read: crash! - if you do it.

In case someone was looking for an answer and landed here like me, from Chrome 34 and Firefox 33 you can do the following:

var form = document.theForm;
var radios = form.elements['genderS'];
alert(radios.value);

or simpler:

alert(document.theForm.genderS.value);

This thing worked for me:

in your question you mentioned that your phpinfo was stating that apache was loading xdebug's configuration in /etc/php5/apache2/conf.d/xdebug.ini In many of the instructions online you may note that they ask you to put xdebug config in php.ini (and that is what I did) HOWEVER, if the configuration is set to /etc/php5/apache2/conf.d/xdebug.ini, then you should remove the [XDebug] configuration settings from /etc/php5/apache2/php.ini and put it in /etc/php5/apache2/conf.d/xdebug.ini INSTEAD. Once I removed from /etc/php5/apache2/php.ini and put in /etc/php5/apache2/conf.d/xdebug.ini instead, and restarted apache, it worked!!

Therefore, in your /etc/php5/apache2/conf.d/xdebug.ini, put the following:

[XDebug]
zend_extension="/usr/lib/php5/20121212+lfs/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_port="9000"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="/home/paul/tmp"

xdebug.remote_host="localhost"
xdebug.remote_handler="dbgp";
xdebug.idekey="phpstorm_xdebug"

then remove this from the /etc/php5/apache2/php.ini if you put it there as well.

Then do:

sudo service apache2 restart

Then it should work!!!

This code is perfectly working for me.

  UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(15,23, 350,22)];

Thank you! I have recently converted to python 3 and have been frustrated by using readlines(0) to read large files. This solved the problem. But to get each line, I had to do a couple extra steps. Each line was preceded by a "b'" which I guess that it was in binary format. Using "decode(utf-8)" changed it ascii.

Then I had to remove a "=\n" in the middle of each line.

Then I split the lines at the new line.

b_data=(fh.read(ele[1]))#endat This is one chunk of ascii data in binary format
        a_data=((binascii.b2a_qp(b_data)).decode('utf-8')) #Data chunk in 'split' ascii format
        data_chunk = (a_data.replace('=\n','').strip()) #Splitting characters removed
        data_list = data_chunk.split('\n')  #List containing lines in chunk
        #print(data_list,'\n')
        #time.sleep(1)
        for j in range(len(data_list)): #iterate through data_list to get each item 
            i += 1
            line_of_data = data_list[j]
            print(line_of_data)

Here is the code starting just above "print data" in Arohi's code.

With LINQ:

List<string> l = new List<string> { "1", "2", "3" ,"4","5"};
List<string> l2 = l.Skip(1).Take(2).ToList();

If you need foreach, then no need for ToList:

foreach (string s in l.Skip(1).Take(2)){}

Advantage of LINQ is that if you want to just skip some leading element,you can :

List<string> l2 = l.Skip(1).ToList();
foreach (string s in l.Skip(1)){}

i.e. no need to take care of count/length, etc.

The method which you are using is rendering login button from the Facebook Javascript code. However, you can write your own Javascript code function to mimic the functionality. Here is how to do it -

1. Create a simple anchor tag link with the image you want to show. Have a onclick method on anchor tag which would actually do the real job.

<a href="#" onclick="fb_login();"><img src="images/fb_login_awesome.jpg" border="0" alt=""></a>

2. Next, we create the Javascript function which will show the actual popup and will fetch the complete user information, if user allows. We also handle the scenario if user disallows our facebook app.

window.fbAsyncInit = function() {
    FB.init({
        appId   : 'YOUR_APP_ID',
        oauth   : true,
        status  : true, // check login status
        cookie  : true, // enable cookies to allow the server to access the session
        xfbml   : true // parse XFBML
    });

  };

function fb_login(){
    FB.login(function(response) {

        if (response.authResponse) {
            console.log('Welcome!  Fetching your information.... ');
            //console.log(response); // dump complete info
            access_token = response.authResponse.accessToken; //get access token
            user_id = response.authResponse.userID; //get FB UID

            FB.api('/me', function(response) {
                user_email = response.email; //get user email
          // you can store this data into your database             
            });

        } else {
            //user hit cancel button
            console.log('User cancelled login or did not fully authorize.');

        }
    }, {
        scope: 'public_profile,email'
    });
}
(function() {
    var e = document.createElement('script');
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    e.async = true;
    document.getElementById('fb-root').appendChild(e);
}());

3. We are done.

Please note that the above function is fully tested and works. You just need to put your facebook APP ID and it will work.

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

To update and/or enhance the answer by @Hans Passant I would separate the retrieval of the property into an extension method. This has the added benefit of removing the nasty magic string in the method GetProperty()

public static class PropertyHelper<T>
{
    public static PropertyInfo GetProperty<TValue>(
        Expression<Func<T, TValue>> selector)
    {
        Expression body = selector;
        if (body is LambdaExpression)
        {
            body = ((LambdaExpression)body).Body;
        }
        switch (body.NodeType)
        {
            case ExpressionType.MemberAccess:
                return (PropertyInfo)((MemberExpression)body).Member;
            default:
                throw new InvalidOperationException();
        }
    }
}

Your test is then reduced to two lines

var property = PropertyHelper<MyClass>.GetProperty(x => x.MyProperty);
Attribute.IsDefined(property, typeof(MyPropertyAttribute));

For the love of all that is holy...

In my case, I had to set the openssl.cafile PHP config variable to the PEM file path.

I trust it is very true that there are many systems where setting curl.cainfo in PHP's config is exactly what is needed, but in the environment I'm working with, which is the eboraas/laravel docker container, which uses Debian 8 (jessie) and PHP 5.6, setting that variable did not do the trick.

I noticed that the output of php -i did not mention anything about that particular config setting, but it did have a few lines about openssl. There is both an openssl.capath and openssl.cafile option, but just setting the second one allowed curl via PHP to finally be okay with HTTPS URLs.

Download the .whl file from this link.

The name of the file is: wxPython-3.0.2.0-cp27-none-win32.whl for Windows 32 bit and python 2.7 and wxPython-3.0.2.0-cp27-none-win_amd64.whl for Windows 64 bit and python 2.7.

Then in the command prompt: pip install location-of-the-above-saved-file

You have a couple options.

1. If you need to do it using only a batch file and native commands, check out How can I auto-elevate my batch file, so that it requests from UAC admin rights if required?.

2. If 3rd-party utilities are an option, you can use a tool like Elevate. It is an executable that you call with the program you want to run elevated as a parameter.
   Like this: elevate net share ....

on unix vim --version tells you the various locations of the vim config files :

   system vimrc file: "$VIM/vimrc"
     user vimrc file: "$HOME/.vimrc"
 2nd user vimrc file: "~/.vim/vimrc"
      user exrc file: "$HOME/.exrc"
       defaults file: "$VIMRUNTIME/defaults.vim"
  fall-back for $VIM: "/usr/share/vim"

case 65: //A
jp = 1;
setTimeout("jp = 0;", 100);

if(pj > 0) {
ABFunction();
pj = 0;
}
break;

case 66: //B
pj = 1;
setTimeout("pj = 0;", 100);

if(jp > 0) {
ABFunction();
jp = 0;
}
break;

Not the best way, I know.

Using WHERE DATE(datetime) = '2009-10-20' has performance issues. As stated here:

• it will calculate DATE() for all rows, including those that don't match.
• it will make it impossible to use an index for the query.

Use BETWEEN or >, <, = operators which allow to use an index:

SELECT * FROM data 
WHERE datetime BETWEEN '2009-10-20 00:00:00' AND '2009-10-20 23:59:59'

Update: the impact on using LIKE instead of operators in an indexed column is high. These are some test results on a table with 1,176,000 rows:

• using datetime LIKE '2009-10-20%' => 2931ms
• using datetime >= '2009-10-20 00:00:00' AND datetime <= '2009-10-20 23:59:59' => 168ms

When doing a second call over the same query the difference is even higher: 2984ms vs 7ms (yes, just 7 milliseconds!). I found this while rewriting some old code on a project using Hibernate.

Haven't used Python in several years, but I would say that it has more to do with it being a dynamically typed language than anything else. For a simple example, in Java, if I wanted to test that something wrote to standard out appropriately I could use DI and pass in any PrintStream to capture the text being written and verify it. When I'm working in Ruby, however, I can dynamically replace the 'puts' method on STDOUT to do the verify, leaving DI completely out of the picture. If the only reason I'm creating an abstraction is to test the class that's using it (think File system operations or the clock in Java) then DI/IoC creates unnecessary complexity in the solution.

A rather separable way of doing this is to use

import tensorflow as tf
from keras import backend as K

num_cores = 4

if GPU:
    num_GPU = 1
    num_CPU = 1
if CPU:
    num_CPU = 1
    num_GPU = 0

config = tf.ConfigProto(intra_op_parallelism_threads=num_cores,
                        inter_op_parallelism_threads=num_cores, 
                        allow_soft_placement=True,
                        device_count = {'CPU' : num_CPU,
                                        'GPU' : num_GPU}
                       )

session = tf.Session(config=config)
K.set_session(session)

Here, with booleans GPU and CPU, we indicate whether we would like to run our code with the GPU or CPU by rigidly defining the number of GPUs and CPUs the Tensorflow session is allowed to access. The variables num_GPU and num_CPU define this value. num_cores then sets the number of CPU cores available for usage via intra_op_parallelism_threads and inter_op_parallelism_threads.

The intra_op_parallelism_threads variable dictates the number of threads a parallel operation in a single node in the computation graph is allowed to use (intra). While the inter_ops_parallelism_threads variable defines the number of threads accessible for parallel operations across the nodes of the computation graph (inter).

allow_soft_placement allows for operations to be run on the CPU if any of the following criterion are met:

1. there is no GPU implementation for the operation

2. there are no GPU devices known or registered

3. there is a need to co-locate with other inputs from the CPU

All of this is executed in the constructor of my class before any other operations, and is completely separable from any model or other code I use.

Note: This requires tensorflow-gpu and cuda/cudnn to be installed because the option is given to use a GPU.

• What do the options in ConfigProto like allow_soft_placement and log_device_placement mean?

• Meaning of inter_op_parallelism_threads and intra_op_parallelism_threads

For what it's worth, if you're using NumPy distutils, numpy.distutils.misc_util.Configuration has a make_svn_version_py() method that embeds the revision number inside package.__svn_version__ in the variable version .

If you are truly comparing date only with no time component, another solution that may feel wrong but works and avoids all Date() time and timezone headaches is to compare the ISO string date directly using string comparison:

> "2019-04-22" <= "2019-04-23"
true
> "2019-04-22" <= "2019-04-22"
true
> "2019-04-22" <= "2019-04-21"
false
> "2019-04-22" === "2019-04-22"
true

You can get the current date (UTC date, not neccesarily the user's local date) using:

> new Date().toISOString().split("T")[0]
"2019-04-22"

My argument in favor of it is programmer simplicity -- you're much less likely to botch this than trying to handle datetimes and offsets correctly, probably at the cost of speed (I haven't compared performance)

This is building off the work Daniel Little did for this question, but taking into account daylight savings time (works for dates 01-01 1902 and greater due to int limit on dateadd function):

We first need to create a table that will store the date ranges for daylight savings time (source: History of time in the United States):

CREATE TABLE [dbo].[CFG_DAY_LIGHT_SAVINGS_TIME](
  [BEGIN_DATE] [datetime] NULL,
  [END_DATE] [datetime] NULL,
  [YEAR_DATE] [smallint] NULL
) ON [PRIMARY]

GO

TL;DR answer - There is no real solution besides "delete app and reinstall".

This answer is not satisfactory for many situations, when you have an existing database that needs to not get deleted within the app.

Lukasz and plivesey are the only ones with solutions that don't require delete, but neither worked for me.

Use Apache Commons Lang:

String a= "\\*\\";
str = StringUtils.replace(xpath, ".", a);

or with standalone JDK:

String a = "\\*\\"; // or: String a = "/*/";
String replacement = Matcher.quoteReplacement(a);
String searchString = Pattern.quote(".");
String str = xpath.replaceAll(searchString, replacement);

This should work.

int i = 1;
foreach (ListViewItem lvi in listView.Items) {
    ...
    if(++i == 50) break;
}

1st solution (fastest) :

yourDateTime.Year % 100

2nd solution (more elegant in my opinion) :

yourDateTime.ToString("yy")

May be there no need for JS. You can achieve this with css also. Write like this:

.flyout {
    position: absolute;
    width: 1000px;
    height: 450px;
    background: red;
    overflow: hidden;
    z-index: 10000;
    display: none;
}
#menu:hover + .flyout {
    display: block;
}

try this can you better fell comparing to another codes.

using namespace std;
int main() {
    int a[5]={4,6,3,5,9};
    for(int i=4;i>=0;i--) {
        cout<<"\n"<<a[i];
    }
}

People may still meeting problems like this when fetching private source:

https fetch: Get "https://private/user/repo?go-get=1": EOF

They can't use private repo without .git extension.

The reason is the go tool has no idea about the VCS protocol of this repo, git or svn or any other, unlike github.com or golang.org them are hardcoded into go's source.

Then the go tool will do a https query before fetching your private repo:

https://private/user/repo?go-get=1

If your private repo has no support for https request, please use replace to tell it directly :

require private/user/repo v1.0.0

...

replace private/user/repo => private.server/user/repo.git v1.0.0

https://golang.org/cmd/go/#hdr-Remote_import_paths

A UNIX guy probably told you that. :)

You can use makefiles in VS, but when you do it bypasses all the built-in functionality in MSVC's IDE. Makefiles are basically the reinterpret_cast of the builder. IMO the simplest thing is just to use Solutions.

If both of your servers are using WHM, I think we can reduce the time to nil. Create your domain in the new server and set everything ready. Go to the previous server and delete the account corresponding to that domain. Until now I have got no errors by doing this and felt the update instantaneous. FYI I used hostgator hosting (both dedicated servers). And I really dont know why it is so. It's supposed to be not like that until the TTL is over.

Out of curiosity, I wanted to see how Value performed against Value2. After about 12 trials of similar processes, I could not see any significant differences in speed so I would always recommend using Value. I used the below code to run some tests with various ranges.

If anyone sees anything contrary regarding performance, please post.

Sub Trial_RUN()
    For t = 0 To 5
        TestValueMethod (True)
        TestValueMethod (False)
    Next t

End Sub




Sub TestValueMethod(useValue2 As Boolean)
Dim beginTime As Date, aCell As Range, rngAddress As String, ResultsColumn As Long
ResultsColumn = 5

'have some values in your RngAddress. in my case i put =Rand() in the cells, and then set to values
rngAddress = "A2:A399999" 'I changed this around on my sets.



With ThisWorkbook.Sheets(1)
.Range(rngAddress).Offset(0, 1).ClearContents


beginTime = Now

For Each aCell In .Range(rngAddress).Cells
    If useValue2 Then
        aCell.Offset(0, 1).Value2 = aCell.Value2 + aCell.Offset(-1, 1).Value2
    Else
        aCell.Offset(0, 1).Value = aCell.Value + aCell.Offset(-1, 1).Value
    End If

Next aCell

Dim Answer As String
 If useValue2 Then Answer = " using Value2"

.Cells(Rows.Count, ResultsColumn).End(xlUp).Offset(1, 0) = DateDiff("S", beginTime, Now) & _
            " seconds. For " & .Range(rngAddress).Cells.Count & " cells, at " & Now & Answer


End With


End Sub

The statement SELECT 1 FROM SomeTable just returns a column containing the value 1 for each row in your table. If you add another column in, e.g. SELECT 1, cust_name FROM SomeTable then it makes it a little clearer:

            cust_name
----------- ---------------
1           Village Toys
1           Kids Place
1           Fun4All
1           Fun4All
1           The Toy Store

ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. (Read More)

ExecuteScalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. (Read More)

ExecuteReader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. (Read More)

        li.Where(w => w.name == "di" )

You can also get an updated version of the Eclipse's ADT plugin (based on an unreleased 24.2.0 version) that I managed to patch and compile at https://github.com/khaledev/ADT.

You can do it like this:

class UsersController < ApplicationController
  ## Exception Handling
  class NotActivated < StandardError
  end

  rescue_from NotActivated, :with => :not_activated

  def not_activated(exception)
    flash[:notice] = "This user is not activated."
    Event.new_event "Exception: #{exception.message}", current_user, request.remote_ip
    redirect_to "/"
  end

  def show
      // Do something that fails..
      raise NotActivated unless @user.is_activated?
  end
end

What you're doing here is creating a class "NotActivated" that will serve as Exception. Using raise, you can throw "NotActivated" as an Exception. rescue_from is the way of catching an Exception with a specified method (not_activated in this case). Quite a long example, but it should show you how it works.

Give margin-top

I run into exactly the same problem and was following this tutorial https://github.com/jverkoey/iOS-Framework#faq

The way that I made this work is after putting into the scripts into your Aggregate's Build Phase, before you compile, make sure you compile it using an iphone simulator (I used iPhone6) instead of IOS Device.

which will give me 2 slices: armv7 and x86_64, then drag and drop it into new project is working fine for me.

Your dataframe has four columns like so df[,c(1,2,3,4)]. Note the first comma means keep all the rows, and the 1,2,3,4 refers to the columns.

To change the order as in the above question do df2[,c(1,3,2,4)]

If you want to output this file as a csv, do write.csv(df2, file="somedf.csv")

Don't forget to export your class or interface as well.

export interface Sort {
    value: string;
    viewValue: string;
}

My problem was in Manifiest file. I have deleted launcher icons and did not reference the new ones on Manifiest :)

This validates dd/mm/yyy dates. Edit your jquery.validate.js and add these.

Reference(Regex): Regex to validate date format dd/mm/yyyy

dateBR: function( value, element ) {
    return this.optional(element) || /^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$/.test(value);
}

messages: {
    dateBR: "Invalid date."
}

classRuleSettings: {
    dateBR: {dateBR: true}
}

Usage:

$( "#myForm" ).validate({
    rules: {
        field: {
            dateBR: true
        }
    }
});

I found that just using Auto-Property Initializer on entity property is enough to get the job done.

For example:

public class Thing {
    public bool IsBigThing{ get; set; } = false;
}

Horrible, I know, but I just couldn't help myself:

namespace ConsoleApplication2
{
    using System;
    using System.Text.RegularExpressions;

    class Program
    {
        static void Main(string[] args)
        {
            Random adomRng = new Random();
            string rndString = string.Empty;
            char c;

            for (int i = 0; i < 8; i++)
            {
                while (!Regex.IsMatch((c=Convert.ToChar(adomRng.Next(48,128))).ToString(), "[A-Za-z0-9]"));
                rndString += c;
            }

            Console.WriteLine(rndString + Environment.NewLine);
        }
    }

I know this post is really old, but I have to reply because although BalusC's answer is marked as correct, it's not completely correct.

You have to write the query adding "[]" to foo like this:

foo[]=val1&foo[]=val2&foo[]=val3

How about this?

public static void printDigits(int num) {
    if(num / 10 > 0) {
        printDigits(num / 10);
    }
    System.out.printf("%d ", num % 10);
}

or instead of printing to the console, we can collect it in an array of integers and then print the array:

public static void main(String[] args) {
    Integer[] digits = getDigits(12345);
    System.out.println(Arrays.toString(digits));
}

public static Integer[] getDigits(int num) {
    List<Integer> digits = new ArrayList<Integer>();
    collectDigits(num, digits);
    return digits.toArray(new Integer[]{});
}

private static void collectDigits(int num, List<Integer> digits) {
    if(num / 10 > 0) {
        collectDigits(num / 10, digits);
    }
    digits.add(num % 10);
}

If you would like to maintain the order of the digits from least significant (index[0]) to most significant (index[n]), the following updated getDigits() is what you need:

/**
 * split an integer into its individual digits
 * NOTE: digits order is maintained - i.e. Least significant digit is at index[0]
 * @param num positive integer
 * @return array of digits
 */
public static Integer[] getDigits(int num) {
    if (num < 0) { return new Integer[0]; }
    List<Integer> digits = new ArrayList<Integer>();
    collectDigits(num, digits);
    Collections.reverse(digits);
    return digits.toArray(new Integer[]{});
}

POCO is simply an object that does not take a dependency on an external framework. It is PLAIN.

Whether a POCO has behaviour or not it's immaterial.

A DTO may be POCO as may a domain object (which would typically be rich in behaviour).

Typically DTOs are more likely to take dependencies on external frameworks (eg. attributes) for serialisation purposes as typically they exit at the boundary of a system.

In typical Onion style architectures (often used within a broadly DDD approach) the domain layer is placed at the centre and so its objects should not, at this point, have dependencies outside of that layer.

• We display the product version somewhere (tiny) in the first screen of the GUI. Because people tend to make mistakes in picking the right version every time. (And keep us developers searching for ages..)

• We've set up TFSBuild to also generate transforms (.mst files) with the configuration for our different environments. (We know about all environments we need to deploy to).

Since the original weblog post by Grant Holliday is down, I copy pasted its contents here:

MSBuild task to generate MSI Transform files from XMLMarch 11 2008

In my previous post I described how you can use MSI Transform (*.mst) files to separate environment-specific configuration settings from a generic MSI package.

Although this provides a level of flexibility in your configuration, there are two down-sides of Transform files:

1. They’re a binary format
2. You can’t “edit” or “view” a transform file. You have to apply it or re-create it to see what changes it includes.

Fortunately we can use the Microsoft Windows Installer Object Library (c:windowssystem32msi.dll) to open MSI “databases” and create transform files.

Credits go again to Alex Shevchuk – From MSI to WiX – Part 7 – Customising installation using Transforms for showing us how to achieve this with VbScript. Essentially all I’ve done is taken Alex’s example and using Interop.WindowsInstaller.dll I’ve implemented an MSBuild task. The MSBuild Task

I kind of fail to see the point, for jqGrid you can use the virtual scrolling functionality:

http://www.trirand.net/aspnetmvc/grid/performancevirtualscrolling

but then again, millions of rows with filtering can be done:

http://www.trirand.net/aspnetmvc/grid/performancelinq

I really fail to see the point of "as if there are no pages" though, I mean... there is no way to display 1,000,000 rows at once in the browser - this is 10MB of HTML raw, I kind of fail to see why users would not want to see the pages.

Anyway...

The following should work:

ABC: *\([a-zA-Z]+\) *(.+)

Explanation:

ABC:            # match literal characters 'ABC:'
 *              # zero or more spaces
\([a-zA-Z]+\)   # one or more letters inside of parentheses
 *              # zero or more spaces
(.+)            # capture one or more of any character (except newlines)

To get your desired grouping based on the comments below, you can use the following:

(ABC:) *(\([a-zA-Z]+\).+)

You may interest in using php's inbuilt function realpath(). and passing a constant DIR

for example: $TargetDirectory = realpath(__DIR__."/../.."); //Will take you 2 folder's back

String realpath() :: Returns canonicalized absolute pathname ..

A litle late perhaps but I would suggest

$(document).ready(function() {
    var layout_select_html = $('#layout_select').html(); //save original dropdown list

    $("#column_select").change(function () {
        var cur_column_val = $(this).val(); //save the selected value of the first dropdown
        $('#layout_select').html(layout_select_html); //set original dropdown list back
        $('#layout_select').children('option').each(function(){ //loop through options
        if($(this).val().indexOf(cur_column_val)== -1){ //do your conditional and if it should not be in the dropdown list
           $(this).remove(); //remove option from list
        }
    });
});

Plain Javascript regex does not handle Unicode letters.

Do not use [^\w\s], this will remove letters with accents (like àèéìòù), not to mention to Cyrillic or Chinese, letters coming from such languages will be completed removed.

You really don't want remove these letters together with all the special characters. You have two chances:

• Add in your regex all the special characters you don't want remove,
  for example: [^èéòàùì\w\s].
• Have a look at xregexp.com. XRegExp adds base support for Unicode matching via the \p{...} syntax.

var str = "????::: résd,$%& adùf"
var search = XRegExp('([^?<first>\\pL ]+)');
var res = XRegExp.replace(str, search, '',"all");

console.log(res); // returns "????::: resd,adf"
console.log(str.replace(/[^\w\s]/gi, '') ); // returns " rsd adf"
console.log(str.replace(/[^\wèéòàùì\s]/gi, '') ); // returns " résd adùf"

For someone who googling this error for MySQL 8.

MySQL 8.0.11 remove the 'NO_AUTO_CREATE_USER' from sql-mode.

MySQL 5.7: Using GRANT to create users. Instead, use CREATE USER. Following this practice makes the NO_AUTO_CREATE_USER SQL mode immaterial for GRANT statements, so it too is deprecated. MySQL 8.0.11: Using GRANT to create users. Instead, use CREATE USER. Following this practice makes the NO_AUTO_CREATE_USER SQL mode immaterial for GRANT statements, so it too is removed.

Taken from here

So, your sql_mode can be like this:

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

Or if you're using Docker you can add next command to docker-compose.yml

  mysql:
    image: mysql:8.0.13
    command: --sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
    ports:
      - 13306:${MYSQL_PORT}

This is also simple crossbrowser solution:

var addEvent =  window.attachEvent||window.addEventListener;
var event = window.attachEvent ? 'onclick' : 'click';
addEvent(event, function(){
    alert('Hello!')
});

Instead of 'click' can be any event of course.

The 2020 answer: it probably doesn't matter

The best answer here was from 2012, so I decided to test for myself. On Chrome for Android, the JS and CSS resources are downloaded in parallel and I could not detect a difference in page rendering speed.

I included a more detailed writeup on my blog

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

If you have your project saved as a local copy of a repository, it may be better to import from git. Select local, and then browse to your git repository folder. That worked better for me than importing it as an existing project. Attempting the latter did not allow me to "finish".

In Terminal:

nano ~/.bash_profile 

Add lines:

export ANDROID_HOME=/YOUR_PATH_TO/android-sdk
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH

Check it worked:

source ~/.bash_profile
echo $ANDROID_HOME

You may want to use the Continue statement to continue with the innermost loop.

Excerpt from PowerShell help file:

In a script, the continue statement causes program flow to move immediately to the top of the innermost loop controlled by any of these statements:

• for
• foreach
• while

If can't rely on the process name like python scripts which will always have python.exe as process name. If found this method very handy

import psutil
psutil.pid_exists(pid)

check docs for further info http://psutil.readthedocs.io/en/latest/#psutil.pid_exists

int day=0,month=0,year=0;
DateTime smallDate = Convert.ToDateTime(string.Format("{0}", "01.01.1900"));
DateTime bigDate = Convert.ToDateTime(string.Format("{0}", "05.06.2019"));
TimeSpan timeSpan = new TimeSpan();

//timeSpan is diff between bigDate and smallDate as days
timeSpan = bigDate - smallDate;

//year is totalDays / 365 as int
year = timeSpan.Days / 365;

//smallDate.AddYears(year) is closing the difference for year because we found the year variable
smallDate = smallDate.AddYears(year);

//again subtraction because we don't need the year now
timeSpan = bigDate - smallDate;

//month is totalDays / 30 as int
month = timeSpan.Days / 30;

//smallDate.AddMonths(month) is closing the difference for month because we found the month variable
smallDate = smallDate.AddMonths(month);
if (bigDate > smallDate)
{
    timeSpan = bigDate - smallDate;
    day = timeSpan.Days;
}
//else it is mean already day is 0

I'm surprised at all the answers here...

Try this:

window.setTimeout(function() { /* your stuff */ }, 0);

Note the 0 timeout. It's not an arbitrary number... as I understand (though my understanding might be a bit shaky), there's two javascript event queues - one for macro events and one for micro events. The "larger" scoped queue holds tasks that update the UI (and DOM), while the micro queue performs quick-task type operations.

Also realize that setting a timeout doesn't guarantee that the code performs exactly at that specified value. What this does is essentially puts the function into the higher queue (the one that handles the UI/DOM), and does not run it before the specified time.

This means that setting a timeout of 0 puts it into the UI/DOM-portion of javascript's event queue, to be run at the next possible chance.

This means that the DOM gets updated with all previous queue items (such as inserted via $.append(...);, and when your code runs, the DOM is fully available.

(p.s. - I learned this from Secrects of the JavaScript Ninja - an excellent book: https://www.manning.com/books/secrets-of-the-javascript-ninja )

Setting window full height for empty divs

1st solution with absolute positioning - FIDDLE

.div1 {
  position: absolute;
  top: 0;
  bottom: 0;
  width: 25%;
}
.div2 {
  position: absolute;
  top: 0;
  left: 25%;
  bottom: 0;
  width: 75%;
}

2nd solution with static (also can be used a relative) positioning & jQuery - FIDDLE

.div1 {
  float: left;
  width: 25%;
}
.div2 {
  float: left;
  width: 75%;
}

$(function(){
  $('.div1, .div2').css({ height: $(window).innerHeight() });
  $(window).resize(function(){
    $('.div1, .div2').css({ height: $(window).innerHeight() });
  });
});

<a onclick="parent.abc();" href="#" >Call Me </a>

See window.parent

Returns a reference to the parent of the current window or subframe.

If a window does not have a parent, its parent property is a reference to itself.

When a window is loaded in an <iframe>, <object>, or <frame>, its parent is the window with the element embedding the window.

key = "".join( chr( val ) for val in myList )

For sake of completeness, as of PHP 5.1 this works, too:

<?php
function title($title, $name) {
    return sprintf("%s. %s\r\n", $title, $name);
}
$function = new ReflectionFunction('title');
$myArray = array('Dr', 'Phil');
echo $function->invokeArgs($myArray);  // prints "Dr. Phil"
?>

See: http://php.net/reflectionfunction.invokeargs

For methods you use ReflectionMethod::invokeArgs instead and pass the object as first parameter.

from datetime import datetime, timedelta

yesterday = datetime.now() - timedelta(days=1)
yesterday.strftime('%m%d%y')

Well you can not run code from notepad so that means you are opening up the page from the file system. aka c:/foo/bar/hello.html

When you run the code from the asp.net page, you are running it from localhost. aka http://loalhost:1234/assdf.html

Each of these run in different security zones on IE.

I've tried with

let UUID = UIDevice.currentDevice().identifierForVendor?.UUIDString

instead

let UUID = NSUUID().UUIDString

and it works.

In my case the reason of the error is library which was linked two times.

I use react-native so it was linked automatically using react-native link and manually in xcode.

This is what operator.itemgetter is for.

>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b
[1, 2]

The itemgetter statement returns a function that returns the index of the element you specify. It's exactly the same as writing

>>> b = map(lambda x: x[0], a)

But I find that itemgetter is a clearer and more explicit.

This is handy for making compact sort statements. For example,

>>> c = sorted(a, key=operator.itemgetter(0), reverse=True)
>>> c
[(2, u'def'), (1, u'abc')]

Just use special `

var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;

You can see more examples here.

Use this instead:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked') //...
});

Let me explain you what the selector does: input[type="checkbox"] means that this will match each <input /> with type attribute type equals to checkbox After that: :checked will match all checked checkboxes.

You can loop over these checkboxes with:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked').each(function () {
       //this is the current checkbox
    });
});

Here is demo in JSFiddle.

And here is a demo which solves exactly your problem http://jsfiddle.net/DuE8K/1/.

$('#save').click(function () {
    $('#mytable').find('tr').each(function () {
        var row = $(this);
        if (row.find('input[type="checkbox"]').is(':checked') &&
            row.find('textarea').val().length <= 0) {
            alert('You must fill the text area!');
        }
    });
});

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-

last_list.append(p.last)

if you assign this to a variable "last_list" again, it will no more be a list (will become a none type variable since you haven't declared the type for that) and append will become invalid in the next run.

Supplementing the answer by p.s.w.g, here are three other ways of achieving this using lodash 4.17.5, without using _.includes():

Say you want to add object entry to an array of objects numbers, only if entry does not exist already.

let numbers = [
    { to: 1, from: 2 },
    { to: 3, from: 4 },
    { to: 5, from: 6 },
    { to: 7, from: 8 },
    { to: 1, from: 2 } // intentionally added duplicate
];

let entry = { to: 1, from: 2 };

/* 
 * 1. This will return the *index of the first* element that matches:
 */
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) });
// output: 0


/* 
 * 2. This will return the entry that matches. Even if the entry exists
 *    multiple time, it is only returned once.
 */
_.find(numbers, (o) => { return _.isMatch(o, entry) });
// output: {to: 1, from: 2}


/* 
 * 3. This will return an array of objects containing all the matches.
 *    If an entry exists multiple times, if is returned multiple times.
 */
_.filter(numbers, _.matches(entry));
// output: [{to: 1, from: 2}, {to: 1, from: 2}]

If you want to return a Boolean, in the first case, you can check the index that is being returned:

_.findIndex(numbers, (o) => { return _.isMatch(o, entry) }) > -1;
// output: true

Update in ASP.NET Core Version >= 2.0

In the Controller:

public class YourControllerNameController : Controller
{
    private readonly UserManager<ApplicationUser> _userManager;
    
    public YourControllerNameController(UserManager<ApplicationUser> userManager)
    {
        _userManager = userManager;
    }

    public async Task<IActionResult> YourMethodName()
    {
        var userId =  User.FindFirstValue(ClaimTypes.NameIdentifier) // will give the user's userId
        var userName =  User.FindFirstValue(ClaimTypes.Name) // will give the user's userName
        
        // For ASP.NET Core <= 3.1
        ApplicationUser applicationUser = await _userManager.GetUserAsync(User);
        string userEmail = applicationUser?.Email; // will give the user's Email

       // For ASP.NET Core >= 5.0
       var userEmail =  User.FindFirstValue(ClaimTypes.Email) // will give the user's Email
    }
}

In some other class:

public class OtherClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    public OtherClass(IHttpContextAccessor httpContextAccessor)
    {
       _httpContextAccessor = httpContextAccessor;
    }

   public void YourMethodName()
   {
      var userId = _httpContextAccessor.HttpContext.User.FindFirstValue(ClaimTypes.NameIdentifier);
   }
}

Then you should register IHttpContextAccessor in the Startup class as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}

For more readability write extension methods as follows:

public static class ClaimsPrincipalExtensions
{
    public static T GetLoggedInUserId<T>(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        var loggedInUserId = principal.FindFirstValue(ClaimTypes.NameIdentifier);

        if (typeof(T) == typeof(string))
        {
            return (T)Convert.ChangeType(loggedInUserId, typeof(T));
        }
        else if (typeof(T) == typeof(int) || typeof(T) == typeof(long))
        {
            return loggedInUserId != null ? (T)Convert.ChangeType(loggedInUserId, typeof(T)) : (T)Convert.ChangeType(0, typeof(T));
        }
        else
        {
            throw new Exception("Invalid type provided");
        }
    }

    public static string GetLoggedInUserName(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Name);
    }

    public static string GetLoggedInUserEmail(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Email);
    }
}

Then use as follows:

public class YourControllerNameController : Controller
{
    public IActionResult YourMethodName()
    {
        var userId = User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
        var userName = User.GetLoggedInUserName();
        var userEmail = User.GetLoggedInUserEmail();
    }
}

public class OtherClass
{
     private readonly IHttpContextAccessor _httpContextAccessor;
     public OtherClass(IHttpContextAccessor httpContextAccessor)
     {
         _httpContextAccessor = httpContextAccessor;
     }

     public void YourMethodName()
     {
         var userId = _httpContextAccessor.HttpContext.User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
     }
}

Instead, you could git CtrlZ and retry the commit but this time add " -m " with a message in quotes after it, then it will commit without prompting you with that page.

In order to change the attribute of the class conditionally,

var css_val = $(".handle").css('left');
if(css_val == '336px')
{
  $(".handle").css('left','300px');
}

If id is given as following,

<a id="handle" class="handle" href="#" style="left: 336px;"></a>

Here is an alternative solution:

var css_val = $("#handle").css('left');
if(css_val == '336px')
{
  $("#handle").css('left','300px');
}

I find, if the data is imported, you may need to use the trim command on top of it, to get your details. =LEFT(TRIM(B2),8) In my case, I was using it to find a IP range. 10.3.44.44 with mask 255.255.255.0, so response is: 10.3.44 Kind of handy.

If you want the default colors of Android ICS, you just have to go to your Android SDK and look for this path: platforms\android-15\data\res\values\colors.xml.

Just solved this problem! I know the question is quite old, but I just had this same problem and none of the answers above helped to solve it.

Assuming the actual domain name you want to use is specified in your c:\windows\System32\drivers\etc\hosts and your configurations in apache\conf\httpd.conf and apache\conf\extra\httpd-vhots.conf are right, your problem might be the same as mine:

In Apache's htdocs directory I had a shortcut linking to the actual project I wanted to see in the browser. It turns out, Apache doesn't understand shortcuts. My solution was to create a proper symlink:

In windows, and within the httdocs directory, I ran this command in the terminal:

mklink /d ple <your project directory with index.html> 

This created a proper symlink in the httpdocs directory. After restarting the Apache service and then reloading the page, I was able to see my website up :)

First we need to understand how normal (without indexing) query runs. It basically traverse each rows one by one and when it finds the data it returns. Refer the following image. (This image has been taken from this video.)

So suppose query is to find 50 , it will have to read 49 records as a linear search.

Refer the following image. (This image has been taken from this video)

When we apply indexing, the query will quickly find out the data without reading each one of them just by eliminating half of the data in each traversal like a binary search. The mysql indexes are stored as B-tree where all the data are in leaf node.

You should drop the old table type and create a new one. However if it has any dependencies (any stored procedures using it) you won't be able to drop it. I've posted another answer on how to automate the process of temporary dropping all stored procedures, modifying the table table and then restoring the stored procedures.

Here is a solution that does not require functions to get an accurate count for each table:

select table_schema, 
       table_name, 
       (xpath('/row/cnt/text()', xml_count))[1]::text::int as row_count
from (
  select table_name, table_schema, 
         query_to_xml(format('select count(*) as cnt from %I.%I', table_schema, table_name), false, true, '') as xml_count
  from information_schema.tables
  where table_schema = 'public' --<< change here for the schema you want
) t

query_to_xml will run the passed SQL query and return an XML with the result (the row count for that table). The outer xpath() will then extract the count information from that xml and convert it to a number

The derived table is not really necessary, but makes the xpath() a bit easier to understand - otherwise the whole query_to_xml() would need to be passed to the xpath() function.

Besides the powerful options on the "Run Configurations.." on a well configured project you'll see the maven tasks on the Run As as well.

What the status is telling you is that you're behind the ref called origin/master which is a local ref in your local repo. In this case that ref happens to track a branch in some remote, called origin, but the status is not telling you anything about the branch on the remote. It's telling you about the ref, which is just a commit ID stored on your local filesystem (in this case, it's typically in a file called .git/refs/remotes/origin/master in your local repo).

git pull does two operations; first it does a git fetch to get up to date with the commits in the remote repo (which updates the origin/master ref in your local repo), then it does a git merge to merge those commits into the current branch.

Until you do the fetch step (either on its own or via git pull) your local repo has no way to know that there are additional commits upstream, and git status only looks at your local origin/master ref.

When git status says up-to-date, it means "up-to-date with the branch that the current branch tracks", which in this case means "up-to-date with the local ref called origin/master". That only equates to "up-to-date with the upstream status that was retrieved last time we did a fetch" which is not the same as "up-to-date with the latest live status of the upstream".

Why does it work this way? Well the fetch step is a potentially slow and expensive network operation. The design of Git (and other distributed version control systems) is to avoid network operations when unnecessary, and is a completely different model to the typical client-server system many people are used to (although as pointed out in the comments below, Git's concept of a "remote tracking branch" that causes confusion here is not shared by all DVCSs). It's entirely possible to use Git offline, with no connection to a centralized server, and the output of git status reflects this.

Creating and switching branches (and checking their status) in Git is supposed to be lightweight, not something that performs a slow network operation to a centralized system. The assumption when designing Git, and the git status output, was that users understand this (too many Git features only make sense if you already know how Git works). With the adoption of Git by lots and lots of users who are not familiar with DVCS this assumption is not always valid.

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

The first thing that comes to mind for me is:

verts = [None]*1000

But do you really need to preinitialize it?

Range.Rows and Range.Columns return essentially the same Range except for the fact that the new Range has a flag which indicates that it represents Rows or Columns. This is necessary for some Excel properties such as Range.Count and Range.Hidden and for some methods such as Range.AutoFit():

• Range.Rows.Count returns the number of rows in Range.
• Range.Columns.Count returns the number of columns in Range.
• Range.Rows.AutoFit() autofits the rows in Range.
• Range.Columns.AutoFit() autofits the columns in Range.

You might find that Range.EntireRow and Range.EntireColumn are useful, although they still are not exactly what you are looking for. They return all possible columns for EntireRow and all possible rows for EntireColumn for the represented range.

I know this because SpreadsheetGear for .NET comes with .NET APIs which are very similar to Excel's APIs. The SpreadsheetGear API comes with several strongly typed overloads to the IRange indexer including the one you probably wish Excel had:

• IRange this[int row1, int column1, int row2, int column2];

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;

u can use this:

protected void btnConfirm_Click(object sender, EventArgs e)
{
  Response.Redirect("Confirm.aspx");
}

Change

int wordLength = wordLengthFunction(string word);

to

int wordLength = wordLengthFunction(word);

This is an important question. The SSL 3 protocol (1996) is irreparably broken by the Poodle attack published 2014. The IETF have published "SSLv3 MUST NOT be used". Web browsers are ditching it. Mozilla Firefox and Google Chrome have already done so.

Two excellent tools for checking protocol support in browsers are SSL Lab's client test and https://www.howsmyssl.com/ . The latter does not require Javascript, so you can try it from .NET's HttpClient:

// set proxy if you need to
// WebRequest.DefaultWebProxy = new WebProxy("http://localhost:3128");

File.WriteAllText("howsmyssl-httpclient.html", new HttpClient().GetStringAsync("https://www.howsmyssl.com").Result);

// alternative using WebClient for older framework versions
// new WebClient().DownloadFile("https://www.howsmyssl.com/", "howsmyssl-webclient.html");

The result is damning:

Your client is using TLS 1.0, which is very old, possibly susceptible to the BEAST attack, and doesn't have the best cipher suites available on it. Additions like AES-GCM, and SHA256 to replace MD5-SHA-1 are unavailable to a TLS 1.0 client as well as many more modern cipher suites.

That's concerning. It's comparable to 2006's Internet Explorer 7.

To list exactly which protocols a HTTP client supports, you can try the version-specific test servers below:

var test_servers = new Dictionary<string, string>();
test_servers["SSL 2"] = "https://www.ssllabs.com:10200";
test_servers["SSL 3"] = "https://www.ssllabs.com:10300";
test_servers["TLS 1.0"] = "https://www.ssllabs.com:10301";
test_servers["TLS 1.1"] = "https://www.ssllabs.com:10302";
test_servers["TLS 1.2"] = "https://www.ssllabs.com:10303";

var supported = new Func<string, bool>(url =>
{
    try { return new HttpClient().GetAsync(url).Result.IsSuccessStatusCode; }
    catch { return false; }
});

var supported_protocols = test_servers.Where(server => supported(server.Value));
Console.WriteLine(string.Join(", ", supported_protocols.Select(x => x.Key)));

I'm using .NET Framework 4.6.2. I found HttpClient supports only SSL 3 and TLS 1.0. That's concerning. This is comparable to 2006's Internet Explorer 7.

Update: It turns HttpClient does support TLS 1.1 and 1.2, but you have to turn them on manually at System.Net.ServicePointManager.SecurityProtocol. See https://stackoverflow.com/a/26392698/284795

I don't know why it uses bad protocols out-the-box. That seems a poor setup choice, tantamount to a major security bug (I bet plenty of applications don't change the default). How can we report it?

I had the same problem. I fixed it by adding this piece of code inside the text area's style.

You can check the Bootstrap reference here

In the web a stateful protocol is based on having a temporary token that is exchanged between a browser and a server (via cookie header or URI rewriting) on every request. That token is usually created on the server end, and it is a piece of opaque data that has a certain time-to-live, and it has the sole purpose of identifying a specific web user agent. That is, the token is temporary, and becomes a STATE that the web server has to maintain on behalf of a client user agent during the duration of that conversation. Therefore, the communication using a token in this way is STATEFUL. And if the conversation between client and server is STATEFUL it is not RESTful.

The username/password (sent on the Authorization header) is usually persisted on the database with the intent of identifying a user. Sometimes the user could mean another application; however, the username/password is NEVER intended to identify a specific web client user agent. The conversation between a web agent and server based on using the username/password in the Authorization header (following the HTTP Basic Authorization) is STATELESS because the web server front-end is not creating or maintaining any STATE information whatsoever on behalf of a specific web client user agent. And based on my understanding of REST, the protocol states clearly that the conversation between clients and server should be STATELESS. Therefore, if we want to have a true RESTful service we should use username/password (Refer to RFC mentioned in my previous post) in the Authorization header for every single call, NOT a sension kind of token (e.g. Session tokens created in web servers, OAuth tokens created in authorization servers, and so on).

I understand that several called REST providers are using tokens like OAuth1 or OAuth2 accept-tokens to be be passed as "Authorization: Bearer " in HTTP headers. However, it appears to me that using those tokens for RESTful services would violate the true STATELESS meaning that REST embraces; because those tokens are temporary piece of data created/maintained on the server side to identify a specific web client user agent for the valid duration of a that web client/server conversation. Therefore, any service that is using those OAuth1/2 tokens should not be called REST if we want to stick to the TRUE meaning of a STATELESS protocol.

Adding to @pranay-rana's list:

Third way is:

function passFromValue(){
    var x = 15;
    return x;  
}
function passToValue() {
    var y = passFromValue();
    console.log(y);//15
}
passToValue(); 

There are some good answers on here, so I will just add some process improvements. A better way of determining if the folder exists (does not use FileSystemObjects, which not all computers are allowed to use):

Function FolderExists(FolderPath As String) As Boolean
     FolderExists = True
     On Error Resume Next
     ChDir FolderPath
     If Err <> 0 Then FolderExists = False
     On Error GoTo 0
End Function

Likewise,

Function FileExists(FileName As String) As Boolean
     If Dir(FileName) <> "" Then FileExists = True Else FileExists = False
EndFunction

ERRORLEVEL will contain the return code of the last command. Sadly you can only check >= for it.

Note specifically this line in the MSDN documentation for the If statement:

errorlevel Number

Specifies a true condition only if the previous program run by Cmd.exe returned an exit code equal to or greater than Number.

So to check for 0 you need to think outside the box:

IF ERRORLEVEL 1 GOTO errorHandling
REM no error here, errolevel == 0
:errorHandling

Or if you want to code error handling first:

IF NOT ERRORLEVEL 1 GOTO no_error
REM errorhandling, errorlevel >= 1
:no_error

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

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

Good luck ;)

You forget to write .show() at the end, which is used to show the toast message.

Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT).show();

It is a common mistake that programmer does, but i am sure after this you won't repeat the mistake again... :D

Is your first element h1 or similar? That element's margin-top could be causing what seems like a margin on body.

Here is a fully worked example based on the top voted answer, which is:

int timeout = 1000;
var task = SomeOperationAsync();
if (await Task.WhenAny(task, Task.Delay(timeout)) == task) {
    // task completed within timeout
} else { 
    // timeout logic
}

The main advantage of the implementation in this answer is that generics have been added, so the function (or task) can return a value. This means that any existing function can be wrapped in a timeout function, e.g.:

Before:

int x = MyFunc();

After:

// Throws a TimeoutException if MyFunc takes more than 1 second
int x = TimeoutAfter(MyFunc, TimeSpan.FromSeconds(1));

This code requires .NET 4.5.

using System.Threading;
using System.Threading.Tasks;

namespace TaskTimeout
{
    public static class Program
    {
        /// <summary>

        /// </summary>
        private static void Main(string[] args)
        {

            // Version without timeout.
            int a = MyFunc();
            Console.Write("Result: {0}\n", a);
            // Version with timeout.
            int b = TimeoutAfter(() => { return MyFunc(); },TimeSpan.FromSeconds(1));
            Console.Write("Result: {0}\n", b);
            // Version with timeout (short version that uses method groups). 
            int c = TimeoutAfter(MyFunc, TimeSpan.FromSeconds(1));
            Console.Write("Result: {0}\n", c);

            // Version that lets you see what happens when a timeout occurs.
            try

                // Task completed within timeout.
                return task.GetAwaiter().GetResult();
            }
            else
            {
                // Task timed out.

    }
}

Caveats

Having given this answer, its generally not a good practice to have exceptions thrown in your code during normal operation, unless you absolutely have to:

• Each time an exception is thrown, its an extremely heavyweight operation,
• Exceptions can slow your code down by a factor of 100 or more if the exceptions are in a tight loop.

Only use this code if you absolutely cannot alter the function you are calling so it times out after a specific TimeSpan.

This answer is really only applicable when dealing with 3rd party library libraries that you simply cannot refactor to include a timeout parameter.

How to write robust code

If you want to write robust code, the general rule is this:

Every single operation that could potentially block indefinitely, must have a timeout.

If you do not observe this rule, your code will eventually hit an operation that fails for some reason, then it will block indefinitely, and your app has just permanently hung.

If there was a reasonable timeout after some time, then your app would hang for some extreme amount of time (e.g. 30 seconds) then it would either display an error and continue on its merry way, or retry.

UPDATE:

This only worked for me because our existing generated html was wacky, generating labels along with radios and giving them both checked attribute.

Never mind, and big ups for Brilliand for bringing it up!

If your label is a sibling of a checkbox (which is usually the case), you can use the ~ sibling selector, and a label[for=your_checkbox_id] to address it... or give the label an id if you have multiple labels (like in this example where I use labels for buttons)

Came here looking for the same - but ended up finding my answer in the docs.

a label element with checked attribute can be selected like so:

label[checked] {
  ...
}

I know it's an old question, but maybe it helps someone out there :)

Nobody likes the "refer to this answer" answers, but in this case it may help: Change an HTML5 input's placeholder color with CSS

Since it's only supported by a couple of browsers, you can try the jQuery placeholder plugin (assuming you can\are using jQuery). It allows you to style the placeholder text via CSS since it's really only a swap trick it does with focus events.

The plugin does not activate on browsers that support it, though, so you can have CSS that targets chrome\firefox and the jQuery plugin's CSS to catch the rest.

The plugin can be found here: https://github.com/mathiasbynens/jquery-placeholder

100% working for me ! After unset elements in array you can use this for re-indexing the array

$result=array_combine(range(1, count($your_array)), array_values($your_array));

That doesn't work because the second parameter should be a mapped entity and of course Integer is not a persistent class (since it doesn't have the @Entity annotation on it).

for you you should do the following:

Query q = em.createNativeQuery("select id from users where username = :username");
q.setParameter("username", "lt");
List<BigDecimal> values = q.getResultList();

or if you want to use HQL you can do something like this:

Query q = em.createQuery("select new Integer(id) from users where username = :username");
q.setParameter("username", "lt");
List<Integer> values = q.getResultList();

Regards.

Another way to applyhorizontalalignment and rotation to each tick label is doing a for loop over the tick labels you want to change:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]
hours_value = np.random.random(len(hours))
days_value = np.random.random(len(days))

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
axs[0].plot(hours,hours_value)
axs[1].plot(days,days_value)

for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

And here is an example if you want to control the location of major and minor ticks:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]

axs[0].plot(hours,np.random.random(len(hours)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.HourLocator(byhour = range(0,25,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[0].xaxis.set_major_locator(x_major_lct)
axs[0].xaxis.set_minor_locator(x_minor_lct)
axs[0].xaxis.set_major_formatter(x_fmt)
axs[0].set_xlabel("minor ticks set to every hour, major ticks start with 00:00")

axs[1].plot(days,np.random.random(len(days)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.DayLocator(bymonthday = range(0,32,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[1].xaxis.set_major_locator(x_major_lct)
axs[1].xaxis.set_minor_locator(x_minor_lct)
axs[1].xaxis.set_major_formatter(x_fmt)
axs[1].set_xlabel("minor ticks set to every day, major ticks show first day of month")
for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

This is a pretty old question, but perhaps this answer can still help someone else.

You can emulate a public constant that is restricted within a class scope by applying the final keyword to a method that returns a pre-defined value, like this:

class Foo {

    // This is a private constant
    final public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

The final keyword on a method prevents an extending class from re-defining the method. You can also place the final keyword in front of the class declaration, in which case the keyword prevents class Inheritance.

To get nearly exactly what Alex was looking for the following code can be used:

final class Constants {

    public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

class Foo {

    static public app()
    {
        return new Constants();
    }
}

The emulated constant value would be accessible like this:

Foo::app()->MYCONSTANT();

If we are not sure that the list is sorted, we could use the built-in min() function, to find the element which has the minimum distance from the specified number.

>>> min(myList, key=lambda x:abs(x-myNumber))
4

Note that it also works with dicts with int keys, like {1: "a", 2: "b"}. This method takes O(n) time.

If the list is already sorted, or you could pay the price of sorting the array once only, use the bisection method illustrated in @Lauritz's answer which only takes O(log n) time (note however checking if a list is already sorted is O(n) and sorting is O(n log n).)

The CSS by Paulius Marciukaitis worked nicely for my Genesis theme, here's what how I further modified it for my requirement:

@media only screen and (max-width: 480px) {
.entry {
background-color: #fff;
margin-bottom: 0;
padding: 10px 8px;

}

I got it to work in phpAdmin , but only when I removed the "Number of records " phrase.

In my version of phpAdmin I could see the box for changing the delimiters.

Also to see the procedure in the database i went to the phpAdmin home, then information_schema database and then the routines table.

<?php
    $array = array("your array");
    $array = array_diff($array, ["element you want to delete"]);
?>

Create your array in the variable $array and then where I have put 'element you want to delete' you put something like: "a". And if you want to delete multiple items then: "a", "b".

Here's a flow chart that illustrates a for loop:

The equivalent C code would be

for(i = 2; i <= 6; i = i + 2) {
    printf("%d\t", i + 1);
}

I found this and several other examples on one of Tenouk's C Laboratory practice worksheets.

There is actually a python library called dataframe_image Just do a

pip install dataframe_image

Do the imports

import pandas as pd
import numpy as np
import dataframe_image as dfi
df = pd.DataFrame(np.random.randn(6, 6), columns=list('ABCDEF'))

and style your table if you want by:

df_styled = df.style.background_gradient() #adding a gradient based on values in cell

and finally:

dfi.export(df_styled,"mytable.png")

Starting from iOS 6 SKStoreProductViewController class was introduced. You can link an app without leaving your app. Code snippet in Swift 3.x/2.x and Objective-C is here.

A SKStoreProductViewController object presents a store that allows the user to purchase other media from the App Store. For example, your app might display the store to allow the user to purchase another app.

From News and Announcement For Apple Developers.

Drive Customers Directly to Your App on the App Store with iTunes Links With iTunes links you can provide your customers with an easy way to access your apps on the App Store directly from your website or marketing campaigns. Creating an iTunes link is simple and can be made to direct customers to either a single app, all your apps, or to a specific app with your company name specified.

To send customers to a specific application: http://itunes.com/apps/appname

To send customers to a list of apps you have on the App Store: http://itunes.com/apps/developername

To send customers to a specific app with your company name included in the URL: http://itunes.com/apps/developername/appname

Additional notes:

You can replace http:// with itms:// or itms-apps:// to avoid redirects.

Please note that itms:// will send the user to the iTunes store and itms-apps:// with send them to the App Store!

For info on naming, see Apple QA1633:

https://developer.apple.com/library/content/qa/qa1633/_index.html.

Edit (as of January 2015):

itunes.com/apps links should be updated to appstore.com/apps. See QA1633 above, which has been updated. A new QA1629 suggests these steps and code for launching the store from an app:

1. Launch iTunes on your computer.
2. Search for the item you want to link to.
3. Right-click or control-click on the item's name in iTunes, then choose "Copy iTunes Store URL" from the pop-up menu.
4. In your application, create an NSURL object with the copied iTunes URL, then pass this object to UIApplication' s openURL: method to open your item in the App Store.

Sample code:

NSString *iTunesLink = @"itms://itunes.apple.com/app/apple-store/id375380948?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

iOS10+:

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink] options:@{} completionHandler:nil];

Swift 4.2

   let urlStr = "itms-apps://itunes.apple.com/app/apple-store/id375380948?mt=8"
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(URL(string: urlStr)!, options: [:], completionHandler: nil)
        
    } else {
        UIApplication.shared.openURL(URL(string: urlStr)!)
    }

None of the answers presented so far has no obvious optimization of using enclosure to initialize once and store regular expressions, for subsequent usages.

// DBJ.ORG string.format function
// usage:   "{0} means 'zero'".format("nula") 
// returns: "nula means 'zero'"
// place holders must be in a range 0-99.
// if no argument given for the placeholder, 
// no replacement will be done, so
// "oops {99}".format("!")
// returns the input
// same placeholders will be all replaced 
// with the same argument :
// "oops {0}{0}".format("!","?")
// returns "oops !!"
//
if ("function" != typeof "".format) 
// add format() if one does not exist already
  String.prototype.format = (function() {
    var rx1 = /\{(\d|\d\d)\}/g, rx2 = /\d+/ ;
    return function() {
        var args = arguments;
        return this.replace(rx1, function($0) {
            var idx = 1 * $0.match(rx2)[0];
            return args[idx] !== undefined ? args[idx] : (args[idx] === "" ? "" : $0);
        });
    }
}());

alert("{0},{0},{{0}}!".format("{X}"));

Also, none of the examples respects format() implementation if one already exists.

I have increased target in my tsconfig.json to enable this feature in TypeScript

{
    "compilerOptions": {
        "target": "es2017",
        ......
    }
}

This will give you a nice object to work with

    function queryParameters () {
        var result = {};

        var params = window.location.search.split(/\?|\&/);

        params.forEach( function(it) {
            if (it) {
                var param = it.split("=");
                result[param[0]] = param[1];
            }
        });

        return result;
    }

And then;

    if (queryParameters().sent === 'yes') { .....

if you are going to step down, then change your project's source to 1.7 as well,

right click on your Project -> Properties -> Sources window 

and set 1.7 here

_{note: however I would suggest you to figure out why it doesn't work on 1.8}

Writing this piece of code fixed my problem:

requests.get(link, headers = {'User-agent': 'your bot 0.1'})

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

Equality operators: == and !=

The == operator, also known as equality or double equal, will return true if both objects are equal and false if they are not.

"koan" == "koan" # Output: => true

The != operator, also known as inequality, is the opposite of ==. It will return true if both objects are not equal and false if they are equal.

"koan" != "discursive thought" # Output: => true

Note that two arrays with the same elements in a different order are not equal, uppercase and lowercase versions of the same letter are not equal and so on.

When comparing numbers of different types (e.g., integer and float), if their numeric value is the same, == will return true.

2 == 2.0 # Output: => true

equal?

Unlike the == operator which tests if both operands are equal, the equal method checks if the two operands refer to the same object. This is the strictest form of equality in Ruby.

Example: a = "zen" b = "zen"

a.object_id  # Output: => 20139460
b.object_id  # Output :=> 19972120

a.equal? b  # Output: => false

In the example above, we have two strings with the same value. However, they are two distinct objects, with different object IDs. Hence, the equal? method will return false.

Let's try again, only this time b will be a reference to a. Notice that the object ID is the same for both variables, as they point to the same object.

a = "zen"
b = a

a.object_id  # Output: => 18637360
b.object_id  # Output: => 18637360

a.equal? b  # Output: => true

eql?

In the Hash class, the eql? method it is used to test keys for equality. Some background is required to explain this. In the general context of computing, a hash function takes a string (or a file) of any size and generates a string or integer of fixed size called hashcode, commonly referred to as only hash. Some commonly used hashcode types are MD5, SHA-1, and CRC. They are used in encryption algorithms, database indexing, file integrity checking, etc. Some programming languages, such as Ruby, provide a collection type called hash table. Hash tables are dictionary-like collections which store data in pairs, consisting of unique keys and their corresponding values. Under the hood, those keys are stored as hashcodes. Hash tables are commonly referred to as just hashes. Notice how the word hashcan refer to a hashcode or to a hash table. In the context of Ruby programming, the word hash almost always refers to the dictionary-like collection.

Ruby provides a built-in method called hash for generating hashcodes. In the example below, it takes a string and returns a hashcode. Notice how strings with the same value always have the same hashcode, even though they are distinct objects (with different object IDs).

"meditation".hash  # Output: => 1396080688894079547
"meditation".hash  # Output: => 1396080688894079547
"meditation".hash  # Output: => 1396080688894079547

The hash method is implemented in the Kernel module, included in the Object class, which is the default root of all Ruby objects. Some classes such as Symbol and Integer use the default implementation, others like String and Hash provide their own implementations.

Symbol.instance_method(:hash).owner  # Output: => Kernel
Integer.instance_method(:hash).owner # Output: => Kernel

String.instance_method(:hash).owner  # Output: => String
Hash.instance_method(:hash).owner  # Output: => Hash

In Ruby, when we store something in a hash (collection), the object provided as a key (e.g., string or symbol) is converted into and stored as a hashcode. Later, when retrieving an element from the hash (collection), we provide an object as a key, which is converted into a hashcode and compared to the existing keys. If there is a match, the value of the corresponding item is returned. The comparison is made using the eql? method under the hood.

"zen".eql? "zen"    # Output: => true
# is the same as
"zen".hash == "zen".hash # Output: => true

In most cases, the eql? method behaves similarly to the == method. However, there are a few exceptions. For instance, eql? does not perform implicit type conversion when comparing an integer to a float.

2 == 2.0    # Output: => true
2.eql? 2.0    # Output: => false
2.hash == 2.0.hash  # Output: => false

Case equality operator: ===

Many of Ruby's built-in classes, such as String, Range, and Regexp, provide their own implementations of the === operator, also known as case-equality, triple equals or threequals. Because it's implemented differently in each class, it will behave differently depending on the type of object it was called on. Generally, it returns true if the object on the right "belongs to" or "is a member of" the object on the left. For instance, it can be used to test if an object is an instance of a class (or one of its subclasses).

String === "zen"  # Output: => true
Range === (1..2)   # Output: => true
Array === [1,2,3]   # Output: => true
Integer === 2   # Output: => true

The same result can be achieved with other methods which are probably best suited for the job. It's usually better to write code that is easy to read by being as explicit as possible, without sacrificing efficiency and conciseness.

2.is_a? Integer   # Output: => true
2.kind_of? Integer  # Output: => true
2.instance_of? Integer # Output: => false

Notice the last example returned false because integers such as 2 are instances of the Fixnum class, which is a subclass of the Integer class. The ===, is_a? and instance_of? methods return true if the object is an instance of the given class or any subclasses. The instance_of method is stricter and only returns true if the object is an instance of that exact class, not a subclass.

The is_a? and kind_of? methods are implemented in the Kernel module, which is mixed in by the Object class. Both are aliases to the same method. Let's verify:

Kernel.instance_method(:kind_of?) == Kernel.instance_method(:is_a?) # Output: => true

Range Implementation of ===

When the === operator is called on a range object, it returns true if the value on the right falls within the range on the left.

(1..4) === 3  # Output: => true
(1..4) === 2.345 # Output: => true
(1..4) === 6  # Output: => false

("a".."d") === "c" # Output: => true
("a".."d") === "e" # Output: => false

Remember that the === operator invokes the === method of the left-hand object. So (1..4) === 3 is equivalent to (1..4).=== 3. In other words, the class of the left-hand operand will define which implementation of the === method will be called, so the operand positions are not interchangeable.

Regexp Implementation of ===

Returns true if the string on the right matches the regular expression on the left. /zen/ === "practice zazen today" # Output: => true # is the same as "practice zazen today"=~ /zen/

Implicit usage of the === operator on case/when statements

This operator is also used under the hood on case/when statements. That is its most common use.

minutes = 15

case minutes
  when 10..20
    puts "match"
  else
    puts "no match"
end

# Output: match

In the example above, if Ruby had implicitly used the double equal operator (==), the range 10..20 would not be considered equal to an integer such as 15. They match because the triple equal operator (===) is implicitly used in all case/when statements. The code in the example above is equivalent to:

if (10..20) === minutes
  puts "match"
else
  puts "no match"
end

Pattern matching operators: =~ and !~

The =~ (equal-tilde) and !~ (bang-tilde) operators are used to match strings and symbols against regex patterns.

The implementation of the =~ method in the String and Symbol classes expects a regular expression (an instance of the Regexp class) as an argument.

"practice zazen" =~ /zen/   # Output: => 11
"practice zazen" =~ /discursive thought/ # Output: => nil

:zazen =~ /zen/    # Output: => 2
:zazen =~ /discursive thought/  # Output: => nil

The implementation in the Regexp class expects a string or a symbol as an argument.

/zen/ =~ "practice zazen"  # Output: => 11
/zen/ =~ "discursive thought" # Output: => nil

In all implementations, when the string or symbol matches the Regexp pattern, it returns an integer which is the position (index) of the match. If there is no match, it returns nil. Remember that, in Ruby, any integer value is "truthy" and nil is "falsy", so the =~ operator can be used in if statements and ternary operators.

puts "yes" if "zazen" =~ /zen/ # Output: => yes
"zazen" =~ /zen/?"yes":"no" # Output: => yes

Pattern-matching operators are also useful for writing shorter if statements. Example:

if meditation_type == "zazen" || meditation_type == "shikantaza" || meditation_type == "kinhin"
  true
end
Can be rewritten as:
if meditation_type =~ /^(zazen|shikantaza|kinhin)$/
  true
end

The !~ operator is the opposite of =~, it returns true when there is no match and false if there is a match.

A comparison between a number and a string use to be false, so, cast you selected value to a string within ngOnInit and it will work.

I had same issue, I filled the mat-select with an enum, using

Object.keys(MyAwesomeEnum).filter(k => !isNaN(Number(k)));

and I had the enum value I wanted to select...

I spent few hours struggling my mind trying to identify why it wasn't working. And I did it just after rendering all the variables being used in the mat-select, the keys collection and the selected... if you have ["0","1","2"] and you want to select 1 (which is a number) 1=="1" is false and because of that nothing is selected.

so, the solution is to cast you selected value to a string within ngOnInit and it will work.

Upcasting and Downcasting:

Upcasting: Casting from Derived-Class to Base Class Downcasting: Casting from Base Class to Derived Class

Let's understand the same as an example:

Consider two classes Shape as My parent class and Circle as a Derived class, defined as follows:

class Shape
{
    public int Width { get; set; }
    public int Height { get; set; }
}

class Circle : Shape
{
    public int Radius { get; set; }
    public bool FillColor { get; set; }
}

Upcasting:

Shape s = new Shape();

Circle c= s;

Both c and s are referencing to the same memory location, but both of them have different views i.e using "c" reference you can access all the properties of the base class and derived class as well but using "s" reference you can access properties of the only parent class.

A practical example of upcasting is Stream class which is baseclass of all types of stream reader of .net framework:

StreamReader reader = new StreamReader(new FileStreamReader());

here, FileStreamReader() is upcasted to streadm reder.

Downcasting:

Shape s = new Circle(); here as explained above, view of s is the only parent, in order to make it for both parent and a child we need to downcast it

var c = (Circle) s;

The practical example of Downcasting is button class of WPF.

Changes to Enterprise App Distribution Coming in iOS 9

iOS 9 introduces a new feature to help protect users from installing in-house apps from untrusted sources. While no new app signing or provisioning methods are required, the way your enterprise users manage in-house apps installed on their iOS 9 devices will change.

In-house apps installed using an MDM solution are explicitly trusted and will no longer prompt the user to trust the developer that signed and provisioned the app. If your enterprise app does not use an MDM solution, users who install your app for the first time will be prompted to trust the developer. All users who install your app for the first time will need an internet connection.

Using a new restriction, organizations can limit the apps installed on their devices to the in-house apps that they create. And a new interface in Settings allows users to see all enterprise apps installed from their organization.

There are two ways to change the dialog button color.

Basic Way

If you just want to change in an activity, write the below two lines after alertDialog.show();

alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.colorPrimary));
alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.colorPrimaryDark));

Recommended

I'll recommend adding a theme for AlertDialog in styles.xml so you don't have to write the same code again and again in each activity/dialog call. You can just create a style and apply that theme on the dialog box. So whenever you want to change the color of AlertDialog box, just change color in styles.xml and all the dialog boxes will be updated in the whole application.

<style name="AlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorPrimary</item>
</style>

And apply the theme in AlertDialog.Builder

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.AlertDialogTheme);

You might want to override the touchesBegan:withEvent: method of the UIView (or subclass) that contains your UIImageView subview.

Within this method, test if any of the UITouch touches fall inside the bounds of the UIImageView instance (let's say it is called imageView).

That is, does the CGPoint element [touch locationInView] intersect with with the CGRect element [imageView bounds]? Look into the function CGRectContainsPoint to run this test.

You can use this command and the video duration is still unaltered.

ffmpeg -i input.mp4 -r 24 output.mp4

There is a much better and easy way that we can do this using ramda.js. Code sample here

const ary = [5, 5, 5, 2, 2, 2, 2, 2, 9, 4]; R.countBy(r=> r)(ary) countBy documentation is at documentation

it can been used the format specifier %x02 that format and output a hex value. For example:

>>> foo = b"tC\xfc}\x05i\x8d\x86\x05\xa5\xb4\xd3]Vd\x9cZ\x92~'6"
>>> res = ""
>>> for b in foo:
...     res += "%02x" % b
... 
>>> print(res)

YAY! Another version

While I find this answer useful, I modified it a bit. This GitHub Gist is the result

Usage

print colors.draw("i'm yellow", bold=True, fg_yellow=True)

In addition, you can wrap common usages:

print colors.error('sorry, ')

Upgrading for Windows Users

Windows users should read Troubleshooting > Upgrading on Windows in the npm wiki.

Upgrading on windows 10 using PowerShell (3rd party edit)

The link above Troubleshooting#upgrading-on-windows points to a github page npm-windows-upgrade the lines below are quotes from the readme. I successfully upgraded from npm 2.7.4 to npm 3.9.3 using node v5.7.0 and powershell (presumably powershell version 5.0.10586.122)

First, ensure that you can execute scripts on your system by running the following command from an elevated PowerShell. To run PowerShell as Administrator, click Start, search for PowerShell, right-click PowerShell and select Run as Administrator.

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force    

Then, to install and use this upgrader tool, run (also from an elevated PowerShell or cmd.exe):

npm install --global --production npm-windows-upgrade
npm-windows-upgrade

For me, ASP.NET 5 is not yet required, I removed update, and then reinstalled ASP.NET 4.5. It's a bit tricky:

1. Removed from control panel "Microsoft ASP.NET 5 RC1 Update1". After that, you will no longer open ASP.NET MVC projects
2. Then I changed the installation of "Microsoft Visual Studio Professional 2015", clicked "Modify", and selected "Microsoft Web Developer Tools"

No longer follow the notification of update in Visual Studio 2015!!!

There's also TryParse.

From MSDN:

private static void TryToParse(string value)
   {
      int number;
      bool result = Int32.TryParse(value, out number);
      if (result)
      {
         Console.WriteLine("Converted '{0}' to {1}.", value, number);         
      }
      else
      {
         if (value == null) value = ""; 
         Console.WriteLine("Attempted conversion of '{0}' failed.", value);
      }
   }

My MySQL says "Incorrect table definition; there can be only one auto column and it must be defined as a key" So when I added primary key as below it started working:

CREATE TABLE book (
   id INT AUTO_INCREMENT NOT NULL,
   accepted_terms BIT(1) NOT NULL,
   accepted_privacy BIT(1) NOT NULL,
   primary key (id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

I understand/hope that the lists have the same length: No, your only bet is going with a plain old standard for loop.

You need to separate the arguments from the file path:

powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"

Another option that may ease the syntax using the File parameter and positional parameters:

powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"

I came across the same error when trying to add the callback to an event listener. Strangely, setting the callback type to EventListener solved it. It looks more elegant than defining a whole function signature as a type, but I'm not sure if this is the correct way to do this.

class driving {
    // the answer from this post - this works
    // private callback: () => void; 

    // this also works!
    private callback:EventListener;

    constructor(){
        this.callback = () => this.startJump();
        window.addEventListener("keydown", this.callback);
    }

    startJump():void {
        console.log("jump!");
        window.removeEventListener("keydown", this.callback);
    }
}

I've hade the same problem. I resolved with

git checkout <name branch>
git pull origin <name branch>
git push origin <name branch>

Works in IE9 documentMode for me.

Without a X-UA-Compatible header/meta to set an explicit documentMode, you'll get a mode based on:

• whether the user has clicked the ‘compatibility view’ button in that domain before;
• perhaps also whether this has happened automatically due to some other content on the site causing IE8/9's renderer to crash and fall back to the old renderer;
• whether the user has opted to put all sites in compatibility view by default;
• whether IE thinks the site is on your intranet and so defaults to compatibility view;
• whether the site in question is in Microsoft's own list of websites that require compatibility view.

You can change these settings from ‘Tools -> Compatibility view settings’ from the IE menu. Of course that menu is now sneakily hidden, so you won't see it until you press Alt.

As a site author, if you're confident that your site complies to standards (renders well in other browsers, and uses feature-sniffing to decide what browser workarounds to use), I suggest using:

<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

or the HTTP header:

X-UA-Compatible: IE=Edge

to get the latest renderer whatever IE version is in use.

I think what you are looking for is

.style1 {
  background: url('http://localhost/msite/images/12.PNG');
  background-repeat: no-repeat;
  background-position: center;
  -webkit-background-size: contain;
  -moz-background-size: contain;
  -o-background-size: contain;
  background-size: contain;
}

The tikz package seems to have what you want.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{snakes}

\begin{document}

  \begin{tikzpicture}[snake=zigzag, line before snake = 5mm, line after snake = 5mm]
    % draw horizontal line   
    \draw (0,0) -- (2,0);
    \draw[snake] (2,0) -- (4,0);
    \draw (4,0) -- (5,0);
    \draw[snake] (5,0) -- (7,0);

    % draw vertical lines
    \foreach \x in {0,1,2,4,5,7}
      \draw (\x cm,3pt) -- (\x cm,-3pt);

    % draw nodes
    \draw (0,0) node[below=3pt] {$ 0 $} node[above=3pt] {$   $};
    \draw (1,0) node[below=3pt] {$ 1 $} node[above=3pt] {$ 10 $};
    \draw (2,0) node[below=3pt] {$ 2 $} node[above=3pt] {$ 20 $};
    \draw (3,0) node[below=3pt] {$  $} node[above=3pt] {$  $};
    \draw (4,0) node[below=3pt] {$ 5 $} node[above=3pt] {$ 50 $};
    \draw (5,0) node[below=3pt] {$ 6 $} node[above=3pt] {$ 60 $};
    \draw (6,0) node[below=3pt] {$  $} node[above=3pt] {$  $};
    \draw (7,0) node[below=3pt] {$ n $} node[above=3pt] {$ 10n $};
  \end{tikzpicture}

I'm not too expert with tikz, but this does give a good timeline, which looks like:

Interesting how powerful yet how helpless PS can be in the same time, coming from a Nix learning PS. after install crgwin/gitbash, you can do any combination in one commands:

size of current folder: du -sk .

size of all files and folders under current directory du -sk *

size of all subfolders (including current folders) find ./ -type d -exec du -sk {} \;

You can solve this by simply adding class to modal-header

<div class="modal-header bg-primary text-white">

Include android:singleLine="true"

• RenderPartial() is a void method that writes to the response stream. A void method, in C#, needs a ; and hence must be enclosed by { }.

• Partial() is a method that returns an MvcHtmlString. In Razor, You can call a property or a method that returns such a string with just a @ prefix to distinguish it from plain HTML you have on the page.

What is happening is that DataTables is setting the CSS width of the table when it is initialised to a calculated value - that value is in pixels, hence why it won't resize with your dragging. The reason it does this is to stop the table and the columns (the column widths are also set) jumping around in width when you change pagination.

What you can do to stop this behaviour in DataTables is set the autoWidth parameter to false.

$('#example').dataTable( {
  "autoWidth": false
} );

That will stop DataTables adding its calculated widths to the table, leaving your (presumably) width:100% alone and allowing it to resize. Adding a relative width to the columns would also help stop the columns bouncing.

One other option that is built into DataTables is to set the sScrollX option to enable scrolling, as DataTables will set the table to be 100% width of the scrolling container. But you might not want scrolling.

The prefect solution would be if I could get the CSS width of the table (assuming one is applied - i.e. 100%), but without parsing the stylesheets, I don't see a way of doing that (i.e. basically I want $().css('width') to return the value from the stylesheet, not the pixel calculated value).

The simplest Solution :

var dt=new DataTable();
dt.Load(myDataReader);
list<DataRow> dr=dt.AsEnumerable().ToList();

This is a simple way to do client-side validation BEFORE the confirmation. It makes use of the built in ASP.NET validation javascript.

<script type="text/javascript">
    function validateAndConfirm() {
        Page_ClientValidate("GroupName");  //'GroupName' is the ValidationGroup
        if (Page_IsValid) {
            return confirm("Are you sure?");
        }
        return false;
    }
</script>

<asp:TextBox ID="IntegerTextBox" runat="server" Width="100px" MaxLength="6" />
<asp:RequiredFieldValidator ID="reqIntegerTextBox" runat="server" ErrorMessage="Required"
    ValidationGroup="GroupName"  ControlToValidate="IntegerTextBox" />
<asp:RangeValidator ID="rangeTextBox" runat="server" ErrorMessage="Invalid"
    ValidationGroup="GroupName" Type="Integer" ControlToValidate="IntegerTextBox" />
<asp:Button ID="SubmitButton" runat="server" Text="Submit"  ValidationGroup="GroupName"
    OnClick="SubmitButton_OnClick" OnClientClick="return validateAndConfirm();" />

First of all, don't loop while (!eof()), it will not work as you expect it to because the eofbit will not be set until after a failed read due to end of file.

Secondly, the normal input operator >> separates on whitespace and so can be used to read "words":

std::string word;
while (file >> word)
{
    ...
}

Implementing the TimeZone class to set the timezone to the Calendar takes care of the daylight savings.

java.util.TimeZone represents a time zone offset, and also figures out daylight savings.

sample code:

TimeZone est_timeZone = TimeZoneIDProvider.getTimeZoneID(TimeZoneID.US_EASTERN).getTimeZone();
Calendar enteredCalendar = Calendar.getInstance();
enteredCalendar.setTimeZone(est_timeZone);

this.HttpContext.Response.StatusCode = 418; // I'm a teapot

How to end the request?

Try other solution, just:

return StatusCode(418);

You could use StatusCode(???) to return any HTTP status code.

Also, you can use dedicated results:

Success:

• return Ok() ? Http status code 200
• return Created() ? Http status code 201
• return NoContent(); ? Http status code 204

Client Error:

• return BadRequest(); ? Http status code 400
• return Unauthorized(); ? Http status code 401
• return NotFound(); ? Http status code 404
