You can easily install it by writing

Install-Package AjaxControlToolkit in package manager console.

Using Kotlin:

You can create an extension function or just use setCompoundDrawablesWithIntrinsicBounds directly.

fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
   this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}

If you need to resize the drawable, you can use this extension function.

textView.leftDrawable(R.drawable.my_icon, R.dimen.icon_size)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int) {
    val drawable = ContextCompat.getDrawable(context, id)
    val size = resources.getDimensionPixelSize(sizeRes)
    drawable?.setBounds(0, 0, size, size)
    this.setCompoundDrawables(drawable, null, null, null)
}

To get really fancy, create a wrapper that allows size and/or color modification.

textView.leftDrawable(R.drawable.my_icon, colorRes = R.color.white)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int = 0, @ColorInt color: Int = 0, @ColorRes colorRes: Int = 0) {
    val drawable = drawable(id)
    if (sizeRes != 0) {
        val size = resources.getDimensionPixelSize(sizeRes)
        drawable?.setBounds(0, 0, size, size)
    }
    if (color != 0) {
        drawable?.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
    } else if (colorRes != 0) {
        val colorInt = ContextCompat.getColor(context, colorRes)
        drawable?.setColorFilter(colorInt, PorterDuff.Mode.SRC_ATOP)
    }
    this.setCompoundDrawables(drawable, null, null, null)
}

I was same problem, but for me the problem was ng build command. I was doing "ng build --prod" i have corrected it to "ng build --prod --base-href /applicationname/". and this solved my problem.

I found that the following code, when inserted into the site's footer, worked well enough:

<script type="text/javascript">
$("#nav-ask").remove();
</script>

This may or may not require jquery. The site I'm editing has jquery, but unfortunately I'm no javascripter, so I only have a limited knowledge of what's going on here, and the requirements of this code snippet...

A data.table approach

library(data.table)
DT <- data.table(myvec)

DT[, .(number_of_distinct_orders = length(unique(order_no))), by = name]

data.table v >= 1.9.5 has a built in uniqueN function now

DT[, .(number_of_distinct_orders = uniqueN(order_no)), by = name]

toString is a method, so you should add parenthesis () to make the function call.

> a = [1,2,3]
[ 1, 2, 3 ]
> a.toString()
'1,2,3'

Besides, if you want to use strings as keys, then you should consider using a Object instead of Array, and use JSON.stringify to return a string.

> var aa = {}
> aa['a'] = 'aaa'
> JSON.stringify(aa)
'{"a":"aaa","b":"bbb"}'

If you want also the position of the new array key to be the same as the old one you can do this:

function change_array_key( $array, $old_key, $new_key) {
    if(!is_array($array)){ print 'You must enter a array as a haystack!'; exit; }
    if(!array_key_exists($old_key, $array)){
        return $array;
    }

    $key_pos = array_search($old_key, array_keys($array));
    $arr_before = array_slice($array, 0, $key_pos);
    $arr_after = array_slice($array, $key_pos + 1);
    $arr_renamed = array($new_key => $array[$old_key]);

    return $arr_before + $arr_renamed + $arr_after;
}

What kind of data?

data: $('#myForm').serialize() + "&moredata=" + morevalue

The "data" parameter is just a URL encoded string. You can append to it however you like. See the API here.

Got it. As a Windows user, I'm used to type executable names without extensions. In my case, I wanted to execute a file called cup.bat. In a Windows shell, typing cup would be enough. Bash doesn't work this way, it wants the full name. Typing cup.bat solved the problem. (I wasn't able to run the file though, since apparently bash couldn't understand its contents)

One more reason to switch to posh-git..

Thanks @Tom for pointing me to the right direction.

The examples in the Python documentation show how to write Unicode CSV files: http://docs.python.org/2/library/csv.html#examples

(can't copy the code here because it's protected by copyright)

x is the target angle. y is the source or starting angle:

atan2(sin(x-y), cos(x-y))

It returns the signed delta angle. Note that depending on your API the order of the parameters for the atan2() function might be different.

Someone mentioned keepAlive capability of TCP Socket. Here it is nicely described:

http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/overview.html

I'm using it this way: after the socket is connected, I'm calling this function, which sets keepAlive on. The keepAliveTime parameter specifies the timeout, in milliseconds, with no activity until the first keep-alive packet is sent. The keepAliveInterval parameter specifies the interval, in milliseconds, between when successive keep-alive packets are sent if no acknowledgement is received.

    void SetKeepAlive(bool on, uint keepAliveTime, uint keepAliveInterval)
    {
        int size = Marshal.SizeOf(new uint());

        var inOptionValues = new byte[size * 3];

        BitConverter.GetBytes((uint)(on ? 1 : 0)).CopyTo(inOptionValues, 0);
        BitConverter.GetBytes((uint)keepAliveTime).CopyTo(inOptionValues, size);
        BitConverter.GetBytes((uint)keepAliveInterval).CopyTo(inOptionValues, size * 2);

        socket.IOControl(IOControlCode.KeepAliveValues, inOptionValues, null);
    }

I'm also using asynchronous reading:

socket.BeginReceive(packet.dataBuffer, 0, 128,
                    SocketFlags.None, new AsyncCallback(OnDataReceived), packet);

And in callback, here is caught timeout SocketException, which raises when socket doesn't get ACK signal after keep-alive packet.

public void OnDataReceived(IAsyncResult asyn)
{
    try
    {
        SocketPacket theSockId = (SocketPacket)asyn.AsyncState;

        int iRx = socket.EndReceive(asyn);
    }
    catch (SocketException ex)
    {
        SocketExceptionCaught(ex);
    }
}

This way, I'm able to safely detect disconnection between TCP client and server.

For .NET 2.0 you could implement a class which inherits from Dictionary and implements ICloneable.

public class CloneableDictionary<TKey, TValue> : Dictionary<TKey, TValue> where TValue : ICloneable
{
    public IDictionary<TKey, TValue> Clone()
    {
        CloneableDictionary<TKey, TValue> clone = new CloneableDictionary<TKey, TValue>();

        foreach (KeyValuePair<TKey, TValue> pair in this)
        {
            clone.Add(pair.Key, (TValue)pair.Value.Clone());
        }

        return clone;
    }
}

You can then clone the dictionary simply by calling the Clone method. Of course this implementation requires that the value type of the dictionary implements ICloneable, but otherwise a generic implementation isn't practical at all.

In IE9+, Chrome or Firefox you can do:

var checkedBoxes = document.querySelectorAll('input[name=mycheckboxes]:checked');

This shall work (modification on above, workaround, not formula)

Modify your original formula: =IF(A1=1,B1,"filler")

Put filter on spreadsheet, choose only "filler" in column B, highlight all the cells with "filler" in them, hit delete, remove filter

I think it's meant to mean nothing. The wiki says:

"Foo is commonly used with the metasyntactic variables bar and foobar."

From looking at the source code, it seems like the pg_stat_database query gives you the number of connections to the current database for all users. On the other hand, the pg_stat_activity query gives the number of connections to the current database for the querying user only.

Functional requirements are those which are related to the technical functionality of the system.

non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system in particular conditions, rather than specific behaviors.

For example if you consider a shopping site, adding items to cart, browsing different items, applying offers and deals and successfully placing orders comes under functional requirements.

Where as performance of the system in peak hours, time taken for the system to retrieve data from DB, security of the user data, ability of the system to handle if large number of users login comes under non functional requirements.

It looks like the DOCTYPE is causing the image to display as an inline element. If I add display: block to the image, problem solved.

innerHTML explanation with example:

The innerHTML manipulates the HTML content of an element(get or set). In the example below if you click on the Change Content link it's value will be updated by using innerHTML property of anchor link Change Content

Example:

<a id="example" onclick='testFunction()'>Change Content</a>_x000D_
_x000D_
<script>_x000D_
  function testFunction(){_x000D_
    // change the content using innerHTML_x000D_
    document.getElementById("example").innerHTML = "This is dummy content";_x000D_
_x000D_
    // get the content using innerHTML_x000D_
    alert(document.getElementById("example").innerHTML)_x000D_
_x000D_
  }_x000D_
</script>_x000D_
    

To convert the int 'x'

int x = 3;

One way, by manipulation on the int :

string s = Convert.ToString(x, 2); //Convert to binary in a string

int[] bits= s.PadLeft(8, '0') // Add 0's from left
             .Select(c => int.Parse(c.ToString())) // convert each char to int
             .ToArray(); // Convert IEnumerable from select to Array

Alternatively, by using the BitArray class-

BitArray b = new BitArray(new byte[] { x });
int[] bits = b.Cast<bool>().Select(bit => bit ? 1 : 0).ToArray();

Yes just add the setters/getters with public modifier ;)

The simplest method to bring a resource from the classpath in the resources directory parsed into a String is the following one liner.

As a String(Using Spring Libraries):

         String resource = StreamUtils.copyToString(
                new ClassPathResource("resource.json").getInputStream(), defaultCharset());

This method uses the StreamUtils utility and streams the file as an input stream into a String in a concise compact way.

If you want the file as a byte array you can use basic Java File I/O libraries:

As a byte array(Using Java Libraries):

byte[] resource = Files.readAllBytes(Paths.get("/src/test/resources/resource.json"));

As in this forum post by Gonzalo Medina, a third way may be:

\documentclass{article}
\usepackage{caption}

\DeclareCaptionType{equ}[][]
%\captionsetup[equ]{labelformat=empty}

\begin{document}

Some text

\begin{equ}[!ht]
  \begin{equation}
    a=b+c
  \end{equation}
\caption{Caption of the equation}
\end{equ}

Some other text
 
\end{document}

More details of the commands used from package caption: here.

A screenshot of the output of the above code:

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

Consider a simple shopping cart application that uses a CartContents class to keep track of the items in the shopping cart and an Order class for processing a purchase. The Order needs to determine the total value of the contents in the cart, it might do that like so:

Tightly Coupled Example:

public class CartEntry
{
    public float Price;
    public int Quantity;
}

public class CartContents
{
    public CartEntry[] items;
}

public class Order
{
    private CartContents cart;
    private float salesTax;

    public Order(CartContents cart, float salesTax)
    {
        this.cart = cart;
        this.salesTax = salesTax;
    }

    public float OrderTotal()
    {
        float cartTotal = 0;
        for (int i = 0; i < cart.items.Length; i++)
        {
            cartTotal += cart.items[i].Price * cart.items[i].Quantity;
        }
        cartTotal += cartTotal*salesTax;
        return cartTotal;
    }
}

Notice how the OrderTotal method (and thus the Order class) depends on the implementation details of the CartContents and the CartEntry classes. If we were to try to change this logic to allow for discounts, we'd likely have to change all 3 classes. Also, if we change to using a List collection to keep track of the items we'd have to change the Order class as well.

Now here's a slightly better way to do the same thing:

Less Coupled Example:

public class CartEntry
{
    public float Price;
    public int Quantity;

    public float GetLineItemTotal()
    {
        return Price * Quantity;
    }
}

public class CartContents
{
    public CartEntry[] items;

    public float GetCartItemsTotal()
    {
        float cartTotal = 0;
        foreach (CartEntry item in items)
        {
            cartTotal += item.GetLineItemTotal();
        }
        return cartTotal;
    }
}

public class Order
{
    private CartContents cart;
    private float salesTax;

    public Order(CartContents cart, float salesTax)
    {
        this.cart = cart;
        this.salesTax = salesTax;
    }

    public float OrderTotal()
    {
        return cart.GetCartItemsTotal() * (1.0f + salesTax);
    }
}

The logic that is specific to the implementation of the cart line item or the cart collection or the order is restricted to just that class. So we could change the implementation of any of these classes without having to change the other classes. We could take this decoupling yet further by improving the design, introducing interfaces, etc, but I think you see the point.

It sounds like IIS is listening to port 80 for HTTP requests.

Try stopping IIS by going into Control Panel/Administrative Tools/Internet Information Services, right-clicking on Default Web Site, and click on the Stop option in the popup menu, and see if the listener on port 80 has cleared.

maybe this is what u want?

If you are dealing with a large df (40m x 700 in my case) it works much faster and memory savvy through iteration on columns with something like.

for col in df.columns:
    df[col][df[col] < 0] = 0

I think you can do this:

var client = new HttpClient();
HttpContent content = new Widget();
client.PostAsync<Widget>("http://localhost:44268/api/test", content, new FormUrlEncodedMediaTypeFormatter())
    .ContinueWith((postTask) => { postTask.Result.EnsureSuccessStatusCode(); });

For those using jQuery there's a convenient method: http://api.jquery.com/change/

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

The next steps after resolving the conflicts manually are:-

1. git add .
2. git status (this will show you which commands are necessary to continue automatic merge procedure)
3. [command git suggests, e.g. git merge --continue, git cherry-pick --continue, git rebase --continue]

I know the question asks about macOS, but here is a solution for Linux users who arrive here via Google.

I was having the issue described in this question, having installed the pdfx package via pip.

When I ran it however, nothing...

pip list | grep pdfx
pdfx (1.3.0)

Yet:

which pdfx
pdfx not found

The problem on Linux is that pip install ... drops scripts into ~/.local/bin and this is not on the default Debian/Ubuntu $PATH.

Here's a GitHub issue going into more detail: https://github.com/pypa/pip/issues/3813

To fix, just add ~/.local/bin to your $PATH, for example by adding the following line to your .bashrc file:

export PATH="$HOME/.local/bin:$PATH"

After that, restart your shell and things should work as expected.

I'd suggest <a href='page1.jsp'>Refresh</a>.

You need to set index=False in to_excel in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html

as you found, this is the preferred sql server method:

SELECT * FROM ( 
  SELECT *, ROW_NUMBER() OVER (ORDER BY name) as row FROM sys.databases 
 ) a WHERE a.row > 5 and a.row <= 10

Sometimes onsubmit wouldn't work with asp.net.

I solved it with very easy way.

if we have such a form

<form method="post" name="setting-form" >
   <input type="text" id="UserName" name="UserName" value="" 
      placeholder="user name" >
   <input type="password" id="Password" name="password" value="" placeholder="password" >
   <div id="remember" class="checkbox">
    <label>remember me</label>
    <asp:CheckBox ID="RememberMe" runat="server" />
   </div>
   <input type="submit" value="login" id="login-btn"/>
</form>

You can now catch get that event before the form postback and stop it from postback and do all the ajax you want using this jquery.

$(document).ready(function () {
            $("#login-btn").click(function (event) {
                event.preventDefault();
                alert("do what ever you want");
            });
 });

Try this way, allow you even filter by other key

data:

var my_data = [{"name":"Lenovo Thinkpad 41A4298","website":"google"},
{"name":"Lenovo Thinkpad 41A2222","website":"google"},
{"name":"Lenovo Thinkpad 41Awww33","website":"yahoo"},
{"name":"Lenovo Thinkpad 41A424448","website":"google"},
{"name":"Lenovo Thinkpad 41A429rr8","website":"ebay"},
{"name":"Lenovo Thinkpad 41A429ff8","website":"ebay"},
{"name":"Lenovo Thinkpad 41A429ss8","website":"rediff"},
{"name":"Lenovo Thinkpad 41A429sg8","website":"yahoo"}];

usage:

//We do that to ensure to get a correct JSON
var my_json = JSON.stringify(my_data)
//We can use {'name': 'Lenovo Thinkpad 41A429ff8'} as criteria too
var filtered_json = find_in_object(JSON.parse(my_json), {website: 'yahoo'});

filter function

function find_in_object(my_object, my_criteria){

  return my_object.filter(function(obj) {
    return Object.keys(my_criteria).every(function(c) {
      return obj[c] == my_criteria[c];
    });
  });

}

def num(s):
    try:
        return int(s)
    except ValueError:
        return float(s)

for (int j=0; j<test.length; j++) {
   System.out.format("%02X ", test[j]);
}
System.out.println();

C++ functions can't return C-style arrays by value. The closest thing is to return a pointer. Furthermore, an array type in the argument list is simply converted to a pointer.

int *fillarr( int arr[] ) { // arr "decays" to type int *
    return arr;
}

You can improve it by using an array references for the argument and return, which prevents the decay:

int ( &fillarr( int (&arr)[5] ) )[5] { // no decay; argument must be size 5
    return arr;
}

With Boost or C++11, pass-by-reference is only optional and the syntax is less mind-bending:

array< int, 5 > &fillarr( array< int, 5 > &arr ) {
    return arr; // "array" being boost::array or std::array
}

The array template simply generates a struct containing a C-style array, so you can apply object-oriented semantics yet retain the array's original simplicity.

Some of you might find this useful. Just copy paste it to your page and you will get a sequence in which events are fired in the Chrome console (Ctrl + Shift + I).

$(document).on('pagebeforecreate',function(){console.log('pagebeforecreate');});
$(document).on('pagecreate',function(){console.log('pagecreate');});
$(document).on('pageinit',function(){console.log('pageinit');});
$(document).on('pagebeforehide',function(){console.log('pagebeforehide');});
$(document).on('pagebeforeshow',function(){console.log('pagebeforeshow');});
$(document).on('pageremove',function(){console.log('pageremove');});
$(document).on('pageshow',function(){console.log('pageshow');});
$(document).on('pagehide',function(){console.log('pagehide');});
$(window).load(function () {console.log("window loaded");});
$(window).unload(function () {console.log("window unloaded");});
$(function () {console.log('document ready');});

You are not going see unload in the console as it is fired when the page is being unloaded (when you move away from the page). Use it like this:

$(window).unload(function () { debugger; console.log("window unloaded");});

And you will see what I mean.

To Start Jenkins through Command Line

To do that in Kotlin:

yourTextView.paint?.isUnderlineText = true

For Windows, you can use winsound. It's built in

import winsound

winsound.PlaySound('sound.wav', winsound.SND_FILENAME)

You should be able to use ossaudiodev for linux:

from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
  from ossaudiodev import AFMT_S16_NE
except ImportError:
  from sys import byteorder
  if byteorder == "little":
    AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
  else:
    AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()

Here is an implementation of an explode function which is available in many other programming languages as a standard function:

type 
  TStringDynArray = array of String;

function Explode(const Separator, S: string; Limit: Integer = 0): TStringDynArray; 
var 
  SepLen: Integer; 
  F, P: PChar; 
  ALen, Index: Integer; 
begin 
  SetLength(Result, 0); 
  if (S = '') or (Limit < 0) then Exit; 
  if Separator = '' then 
  begin 
    SetLength(Result, 1); 
    Result[0] := S; 
    Exit; 
  end; 
  SepLen := Length(Separator); 
  ALen := Limit; 
  SetLength(Result, ALen); 

  Index := 0; 
  P := PChar(S); 
  while P^ <> #0 do 
  begin 
    F := P; 
    P := AnsiStrPos(P, PChar(Separator)); 
    if (P = nil) or ((Limit > 0) and (Index = Limit - 1)) then P := StrEnd(F); 
    if Index >= ALen then 
    begin 
      Inc(ALen, 5); 
      SetLength(Result, ALen); 
    end; 
    SetString(Result[Index], F, P - F); 
    Inc(Index); 
    if P^ <> #0 then Inc(P, SepLen); 
  end; 
  if Index < ALen then SetLength(Result, Index); 
end; 

Sample usage:

var
  res: TStringDynArray;
begin
  res := Explode(':', yourString);

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.

Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.

HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.

Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.

The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.

(Updated to cover implications of making the connection SSL-only.)

• Amd64: A 64-bit processor based on the x64 architecture.
• Arm: An ARM processor.
• IA64: A 64-bit Intel Itanium processor only.
• MSIL: Neutral with respect to processor and bits-per-word.
• X86: A 32-bit Intel processor, either native or in the Windows on Windows environment on a 64-bit platform (WOW64).
• None: An unknown or unspecified combination of processor and bits-per-word.

I'm using PowerShell in this example to call the method.

     self.view.addGestureRecognizer(tapRec)

alert and notify-send seem to be the same thing. I use notify-send for non-input messages as it doesn't steal focus and I cannot find a way to stop zenity etc. from doing this.

e.g.

# This will display message and then disappear after a delay:
notify-send "job complete"

# This will display message and stay on-screen until clicked:
notify-send -u critical "job complete"

As the plural in getElementsByName() implies, does it always return list of elements that have this name. So when you have an input element with that name:

<input type="text" name="Tue">

And it is the first one with that name, you have to use document.getElementsByName('Tue')[0] to get the first element of the list of elements with this name.

Beside that are properties case sensitive and the correct spelling of the value property is .value.

As Jon Skeet commented, you should close your file in the finally {...} block, to ensure that it's always closed. And, instead of swallowing the exceptions with the e.printStackTrace, simply don't catch and add the exception to the method signature. If you can't for any reason, at least do this:

catch(IOException ex) {
    throw new RuntimeException("Error processing file XYZ", ex);
}

Now, question number #2:

What if you do this:

...
to.close();
System.out.println("Please delete the file and press <enter> afterwards!");
System.in.read();
...

Would you be able to delete the file?

Also, files are flushed when they're closed. I use IOUtils.closeQuietly(...), so I use the flush method to ensure that the contents of the file are there before I try to close it (IOUtils.closeQuietly doesn't throw exceptions). Something like this:

...
try {
    ...
    to.flush();
} catch(IOException ex) {
    throw new CannotProcessFileException("whatever", ex);
} finally {
    IOUtils.closeQuietly(to);
}

So I know that the contents of the file are in there. As it usually matters to me that the contents of the file are written and not if the file could be closed or not, it really doesn't matter if the file was closed or not. In your case, as it matters, I would recommend closing the file yourself and treating any exceptions according.

Other answers here work fine, but AES is a more secure and up-to-date encryption algorithm. This is a class that I obtained a few years ago to perform AES encryption that I have modified over time to be more friendly for web applications (e,g. I've built Encrypt/Decrypt methods that work with URL-friendly string). It also has the methods that work with byte arrays.

NOTE: you should use different values in the Key (32 bytes) and Vector (16 bytes) arrays! You wouldn't want someone to figure out your keys by just assuming that you used this code as-is! All you have to do is change some of the numbers (must be <= 255) in the Key and Vector arrays (I left one invalid value in the Vector array to make sure you do this...). You can use https://www.random.org/bytes/ to generate a new set easily:

• generate Key
• generate Vector

Using it is easy: just instantiate the class and then call (usually) EncryptToString(string StringToEncrypt) and DecryptString(string StringToDecrypt) as methods. It couldn't be any easier (or more secure) once you have this class in place.

You can also set LD_RUN_PATH to /usr/local/lib in your user environment when you compile pycurl in the first place. This will embed /usr/local/lib in the RPATH attribute of the C extension module .so so that it automatically knows where to find the library at run time without having to have LD_LIBRARY_PATH set at run time.

Another way (for 2000 / 2005/2012/2014):

IF ((SELECT OBJECTPROPERTY( OBJECT_ID(N'table_name_here'), 'TableHasIdentity')) = 1)
    PRINT 'Yes'
ELSE
    PRINT 'No'

NOTE: table_name_here should be schema.table, unless the schema is dbo.

We can custom A new String type via define new Type with Format support.

package main

import (
    "fmt"
    "text/template"
    "strings"
)

type String string
func (s String) Format(data map[string]interface{}) (out string, err error) {
    t := template.Must(template.New("").Parse(string(s)))
    builder := &strings.Builder{}
    if err = t.Execute(builder, data); err != nil {
        return
    }
    out = builder.String()
    return
}


func main() {
    const tmpl = `Hi {{.Name}}!  {{range $i, $r := .Roles}}{{if $i}}, {{end}}{{.}}{{end}}`
    data := map[string]interface{}{
        "Name":     "Bob",
        "Roles":    []string{"dbteam", "uiteam", "tester"},
    }

    s ,_:= String(tmpl).Format(data)
    fmt.Println(s)
}

In Bash 4 (as well as ZSH 4.3.11):

I was having problems here (i.e. sending form-data whilst uploading a file) until I used the following:

files = {'file': (filename, open(filepath, 'rb'), 'text/xml'),
         'Content-Disposition': 'form-data; name="file"; filename="' + filename + '"',
         'Content-Type': 'text/xml'}

That's the input that ended up working for me. In Chrome Dev Tools -> Network tab, I clicked the request I was interested in. In the Headers tab, there's a Form Data section, and it showed both the Content-Disposition and the Content-Type headers being set there.

I did NOT need to set headers in the actual requests.post() command for this to succeed (including them actually caused it to fail)

If you want to make sure the HTML file doesn't contain any PHP code and will not be executed as PHP, do not use include or require. Simply do:

echo file_get_contents("/path/to/file.html");

Walkthrough of creating and deleting an environment variable in bash:

Test if the DUALCASE variable exists:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

It does not, so create the variable and export it:

el@apollo:~$ DUALCASE=1
el@apollo:~$ export DUALCASE

Check if it is there:

el@apollo:~$ env | grep DUALCASE
DUALCASE=1

It is there. So get rid of it:

el@apollo:~$ unset DUALCASE

Check if it's still there:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

The DUALCASE exported environment variable is deleted.

Extra commands to help clear your local and environment variables:

Unset all local variables back to default on login:

el@apollo:~$ CAN="chuck norris"
el@apollo:~$ set | grep CAN
CAN='chuck norris'
el@apollo:~$ env | grep CAN
el@apollo:~$
el@apollo:~$ exec bash
el@apollo:~$ set | grep CAN
el@apollo:~$ env | grep CAN
el@apollo:~$

exec bash command cleared all the local variables but not environment variables.

Unset all environment variables back to default on login:

el@apollo:~$ export DOGE="so wow"
el@apollo:~$ env | grep DOGE
DOGE=so wow
el@apollo:~$ env -i bash
el@apollo:~$ env | grep DOGE
el@apollo:~$

env -i bash command cleared all the environment variables to default on login.

For Windows/WSL/Cygwin etc users:

Make sure that your line endings are standard Unix line feeds, i.e. \n (LF) only.

Using Windows line endings \r\n (CRLF) line endings will break the command line break.

This is because having \ at the end of a line with Windows line ending translates to \ \r \n.
As Mark correctly explains above:

The line-continuation will fail if you have whitespace after the backslash and before the newline.

This includes not just space () or tabs (\t) but also the carriage return (\r).

You can try:

ps | grep `echo $$` | awk '{ print $4 }'

Or:

echo $SHELL

This is another simple solution. Works in 24 as well

(set-default-font "Monaco 14")

Short cuts:

`C-+` increases font size
`C--` Decreases font size

The code is

document.addEventListener('keydown', function(event){
    alert(event.keyCode);
} );

This return the ascii code of the key. If you need the key representation, use event.key (This will return 'a', 'o', 'Alt'...)

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

.highlight { background-color: red; }

If you want multiple selections

$("#data tr").click(function() {
    $(this).toggleClass("highlight");
});

If you want only 1 row in the table to be selected at a time

$("#data tr").click(function() {
    var selected = $(this).hasClass("highlight");
    $("#data tr").removeClass("highlight");
    if(!selected)
            $(this).addClass("highlight");
});

Also note your TABLE tag has 2 ID attributes, you can't do that.

When you don't care about removing the Html Dom-Element, use *ngIf.

Otherwise, use this:

<div [style.visibility]="(numberOfUnreadAlerts == 0) ? 'hidden' : 'visible' ">
   COUNTER: {{numberOfUnreadAlerts}} 
</div>

    void CallFunction ()
    {   // <----- At this point the compiler knows
        //        nothing about the members of B.
        B b;
        b.bFunction();
    }

This happens for the same reason that functions in C cannot call each other without at least one of them being declared as a function prototype.

To fix this issue we need to make sure both classes are declared before they are used. We separate the declaration from the definition. This MSDN article explains in more detail about the declarations and definitions.

class A
{
public:
    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
    { ... }
};

void A::CallFunction ()
{
    B b;
    b.bFunction();
}

If you want to print the last 10 lines, use

tail(dataset, 10)

for the first 10, you could also do

head(dataset, 10)

Dynamic (run time) polymorphism is the polymorphism existed at run-time. Here, Java compiler does not understand which method is called at compilation time. Only JVM decides which method is called at run-time. Method overloading and method overriding using instance methods are the examples for dynamic polymorphism.

For example,

• Consider an application that serializes and de-serializes different types of documents.

• We can have ‘Document’ as the base class and different document type classes deriving from it. E.g. XMLDocument , WordDocument , etc.

• Document class will define ‘ Serialize() ’ and ‘ De-serialize() ’ methods as virtual and each derived class will implement these methods in its own way based on the actual contents of the documents.

• When different types of documents need to be serialized/de-serialized, the document objects will be referred by the ‘ Document’ class reference (or pointer) and when the ‘ Serialize() ’ or ‘ De-serialize() ’ method are called on it, appropriate versions of the virtual methods are called.

Static (compile time) polymorphism is the polymorphism exhibited at compile time. Here, Java compiler knows which method is called. Method overloading and method overriding using static methods; method overriding using private or final methods are examples for static polymorphism

For example,

• An employee object may have two print() methods one taking no arguments and one taking a prefix string to be displayed along with the employee data.

• Given these interfaces, when the print() method is called without any arguments, the compiler, looking at the function arguments knows which function is meant to be called and it generates the object code accordingly.

For more details please read "What is Polymorphism" (Google it).

In 2019, I would suggest putting all the item animations into the ItemAnimator.

Let's start with declaring the animator in the recycler-view:

with(view.recycler_view) {
adapter = Adapter()
itemAnimator = CustomAnimator()
}

Declare the custom animator then,

class CustomAnimator() : DefaultItemAnimator() {

     override fun animateAppearance(
       holder: RecyclerView.ViewHolder,
       preInfo: ItemHolderInfo?,
       postInfo: ItemHolderInfo): Boolean{} // declare  what happens when a item appears on the recycler view

     override fun animatePersistence(
       holder: RecyclerView.ViewHolder,
       preInfo: ItemHolderInfo,
       postInfo: ItemHolderInfo): Boolean {} // declare animation for items that persist in a recycler view even when the items change

}

Similar to the ones above there is one for disappearance animateDisappearance, for add animateAdd, for change animateChange and move animateMove.

One important point would be to call the correct animation-dispatchers inside them.

USE BINARY_CHECKSUM

SELECT 
FROM Users
WHERE   
    BINARY_CHECKSUM(Username) = BINARY_CHECKSUM(@Username)
    AND BINARY_CHECKSUM(Password) = BINARY_CHECKSUM(@Password)

I tried changing year to a different term, and it worked.

public_methods : {
    get: function() {
        return this._year;
    },

    set: function(newValue) {
        if(newValue > this.originYear) {
            this._year = newValue;
            this.edition += newValue - this.originYear;
        }
    }
}

if you just need it for db-related stuff, some OR Mappers (e.g. NHibernate) support transactinos out of the box per default.

Note: this only answers part of the question.

If you just want to know the maximum number of sessions allowed, then you can execute in sqlplus, as sysdba:

sessions                             integer     248
shared_server_sessions               integer

The sessions parameter is the one what you want.

Notice that the http code response status you are getting is an HTTP 404. The 404 or Not Found error message is a response code indicating that the client was able to communicate with a given server, but the server could not find what was requested.

If you have got an 403 Forbidden vs 401 Unauthorized HTTP responses then it might make a sense to review your tomcat-users.xml.

Resuming: check the manager resources and files of your server installation, some file/directory might be missing, or the path to the manager resources has been changed.

You can handle it in different ways,

Objective is to check if the div exist then execute the code. Simple.

Condition:

$('#myDiv').length

Note:

#myDiv -> < div id='myDiv' > <br>
.myDiv -> < div class='myDiv' > 

This will return a number every time it is executed so if there is no div it will give a Zero [0], and as we no 0 can be represented as false in binary so you can use it in if statement. And you can you use it as a comparison with a none number. while any there are three statement given below

// Statement 0
// jQuery/Ajax has replace [ document.getElementById with $ sign ] and etc
// if you don't want to use jQuery/ajax 

   if (document.getElementById(name)) { 
      $("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
    }

// Statement 1
   if ($('#'+ name).length){ // if 0 then false ; if not 0 then true
       $("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
    }

// Statement 2
    if(!$('#'+ name).length){ // ! Means Not. So if it 0 not then [0 not is 1]
           $("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>"); 
    }
// Statement 3
    if ($('#'+ name).length > 0 ) {
      $("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
    }

// Statement 4
    if ($('#'+ name).length !== 0 ) { // length not equal to 0 which mean exist.
       $("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
    }

You must ensure the URL contains embed rather watch as the /embed endpoint allows outside requests, whereas the /watch endpoint does not.

If you're running this on a cluster then println won't print back to your context. You need to bring the RDD data to your session. To do this you can force it to local array and then print it out:

linesWithSessionId.toArray().foreach(line => println(line))

1.

Add the applicationId to the application's build.gradle:

android {
    ...
    defaultConfig {
        applicationId "com.example.my.app"
        ...
    }
}

And than Clean Project -> Build or Rebuild Project

2. If your minSdkVersion <= 20 (https://developer.android.com/studio/build/multidex)

Use Multidex correctly.

application's build.gradle

    ...
}

manifest.xml

<application
    ...
    android:name="android.support.multidex.MultiDexApplication" >
    ...

If you use a custom Application class

public class MyApplication extends MultiDexApplication {
    @Override
    protected void attachBaseContext(Context context) {
        super.attachBaseContext(context);
        MultiDex.install(this);
    }
}

manifest.xml

<application
    ...
    android:name="com.example.my.app.MyApplication" >
    ...

I found a faster way to solve the problem, at least on realistically large datasets using: df.set_index(KEY).to_dict()[VALUE]

Proof on 50,000 rows:

df = pd.DataFrame(np.random.randint(32, 120, 100000).reshape(50000,2),columns=list('AB'))
df['A'] = df['A'].apply(chr)

%timeit dict(zip(df.A,df.B))
%timeit pd.Series(df.A.values,index=df.B).to_dict()
%timeit df.set_index('A').to_dict()['B']

Output:

100 loops, best of 3: 7.04 ms per loop  # WouterOvermeire
100 loops, best of 3: 9.83 ms per loop  # Jeff
100 loops, best of 3: 4.28 ms per loop  # Kikohs (me)

require 'json/ext' # to use the C based extension instead of json/pure

puts {hash: 123}.to_json

I ran into this problem myself and realized that it was because of a side-effect of a Filter that I created which was filtering all requests on the appliation. As soon as I modified the filter to pick only certain requests, this problem did not occur. It maybe good to check for such filters in your application and see how they behave.

Create a custom authorization attribute based on AuthorizeAttribute and override OnAuthorization to perform the check how you want it done. Normally, AuthorizeAttribute will set the filter result to HttpUnauthorizedResult if the authorization check fails. You could have it set it to a ViewResult (of your Error view) instead.

EDIT: I have a couple of blog posts that go into more detail:

• http://farm-fresh-code.blogspot.com/2011/03/revisiting-custom-authorization-in.html
• http://farm-fresh-code.blogspot.com/2009/11/customizing-authorization-in-aspnet-mvc.html

Example:

    [AttributeUsage( AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false )]
    public class MasterEventAuthorizationAttribute : AuthorizeAttribute
    {
        /// <summary>
        /// The name of the master page or view to use when rendering the view on authorization failure.  Default
        /// is null, indicating to use the master page of the specified view.
        /// </summary>
        public virtual string MasterName { get; set; }

        /// <summary>
        /// The name of the view to render on authorization failure.  Default is "Error".
        /// </summary>
        public virtual string ViewName { get; set; }

        public MasterEventAuthorizationAttribute()
            : base()
        {
            this.ViewName = "Error";
        }

        protected void CacheValidateHandler( HttpContext context, object data, ref HttpValidationStatus validationStatus )
        {
            validationStatus = OnCacheAuthorization( new HttpContextWrapper( context ) );
        }

        public override void OnAuthorization( AuthorizationContext filterContext )
        {
            if (filterContext == null)
            {
                throw new ArgumentNullException( "filterContext" );
            }

            if (AuthorizeCore( filterContext.HttpContext ))
            {
                SetCachePolicy( filterContext );
            }
            else if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
            {
                // auth failed, redirect to login page
                filterContext.Result = new HttpUnauthorizedResult();
            }
            else if (filterContext.HttpContext.User.IsInRole( "SuperUser" ))
            {
                // is authenticated and is in the SuperUser role
                SetCachePolicy( filterContext );
            }
            else
            {
                ViewDataDictionary viewData = new ViewDataDictionary();
                viewData.Add( "Message", "You do not have sufficient privileges for this operation." );
                filterContext.Result = new ViewResult { MasterName = this.MasterName, ViewName = this.ViewName, ViewData = viewData };
            }

        }

        protected void SetCachePolicy( AuthorizationContext filterContext )
        {
            // ** IMPORTANT **
            // Since we're performing authorization at the action level, the authorization code runs
            // after the output caching module. In the worst case this could allow an authorized user
            // to cause the page to be cached, then an unauthorized user would later be served the
            // cached page. We work around this by telling proxies not to cache the sensitive page,
            // then we hook our custom authorization code into the caching mechanism so that we have
            // the final say on whether a page should be served from the cache.
            HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache;
            cachePolicy.SetProxyMaxAge( new TimeSpan( 0 ) );
            cachePolicy.AddValidationCallback( CacheValidateHandler, null /* data */);
        }


    }

A bit late, but I just stumbled across the same problem while trying to provide analytics for my web app that involved sending app version based on the package.json version.

Configuration is as follows: React + Redux, Webpack 3.5.6

The json-loader isn't doing much since Webpack 2+, so after some fiddling with it, I ended up removing it.

The solution that actually worked for me, was simply using fetch. While this will most probably enforce some code changes to adapt to the async approach, it worked perfectly, especially given the fact that fetch will offer json decoding on the fly.

So here it is:

  fetch('../../package.json')
  .then(resp => resp.json())
  .then((packageJson) => {
    console.log(packageJson.version);
  });

Do keep in mind, that since we're talking about package.json specifically here, the file will not usually come bundled in your production build (or even dev for that matter), so you will have to use the CopyWebpackPlugin to have access to it when using fetch.

system "sleep 0.1";

does the trick.

And this is an alternative.If you are returning as list then it is simple to get the values.

def select_choice():
    ...
    return [i, card]

values = select_choice()

print values[0]
print values[1]

alert("I will get back to you soon\nThanks and Regards\nSaurav Kumar");

or %0D%0A in a url

you need to forward declare the name of the class if you don't want a header:

class ClassTwo;

Important: This only works in some cases, see Als's answer for more information..

$newDate = preg_replace("/(\d+)\D+(\d+)\D+(\d+)/","$3-$2-$1",$originalDate);

This code works for every date format.

You can change the order of replacement variables such $3-$1-$2 due to your old date format.

No. Any valid string is a valid key. It can even have " as long as you escape it:

{"The \"meaning\" of life":42}

There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

Why don't you use a separate CSS file to maintain the height and the width of the image you want to display? In that way, you can provide the width and height necessarily.

eg:

       image {
       width: 64px;
       height: 64px;
       }

This Client side verification of reCaptcha - the following worked for me :

if reCaptcha is not validated on client side grecaptcha.getResponse(); returns null, else is returns a value other than null.

Javascript Code:

var response = grecaptcha.getResponse();

if(response.length == 0)
    //reCaptcha not verified

else
    //reCaptch verified

Listing a public key in .ssh/authorized_keys is necessary, but not sufficient for sshd (server) to accept it. If your private key is passphrase-protected, you'll need to give ssh (client) the passphrase every time. Or you can use ssh-agent, or a GNOME equivalent.

Your updated trace is consistent with a passphrase-protected private key. See ssh-agent, or use ssh-keygen -p.

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

if (rs == null || !rs.first()) {
    //empty
} else {
    //not empty
}

Note that after this method call, if the resultset is not empty, it is at the beginning.

The LogManager class determines which log4j config to use in a static block which runs when the class is loaded. There are three options intended for end-users:

1. If you specify log4j.defaultInitOverride to false, it will not configure log4j at all.

2. Specify the path to the configuration file manually yourself and override the classpath search. You can specify the location of the configuration file directly by using the following argument to java:

   -Dlog4j.configuration=<path to properties file>

   in your test runner configuration.

3. Allow log4j to scan the classpath for a log4j config file during your test. (the default)

See also the online documentation.

You can use the ObjectOutputStream class to write objects to an underlying stream.

outputStream = new ObjectOutputStream(new FileOutputStream(filename));
outputStream.writeObject(x);

And read the Object back like -

inputStream = new ObjectInputStream(new FileInputStream(filename));
x = (int[])inputStream.readObject()

You don't see anything, because of buffering. The output is shown, when there are enough lines or end of file is reached. tail -f means wait for more input, but there are no more lines in file and so the pipe to grep is never closed.

If you omit -f from tail the output is shown immediately:

tail file | grep A1 | awk '{print $NF}'

@EdMorton is right of course. Awk can search for A1 as well, which shortens the command line to

tail file | awk '/A1/ {print $NF}'

or without tail, showing the last column of all lines containing A1

awk '/A1/ {print $NF}' file

Thanks to @MitchellTracy's comment, tail might miss the record containing A1 and thus you get no output at all. This may be solved by switching tail and awk, searching first through the file and only then show the last line:

awk '/A1/ {print $NF}' file | tail -n1

My team would stumble upon this issue every now and then in random machines that we would try to install our platform in (we use oracle drivers 12c ver 12.2.0.4 but we came across this bug with other versions as well)

After quite a bit of experimentation we realized what was wrong:

Said machines would have apps that were using the machine-wide oracle drivers silently locking them and preventing the oracle driver-installer from working its magic when would attempt to upgrade/reinstall said oracle-drivers. The sneakiest "app" would be websites running in IIS and the like because these apps essentially auto-start on reboot. To counter this we do the following:

1. Disable IIS from starting automagically on restart. Do the same for any other apps/services that auto-start themselves on reboot.
2. Uninstall any previous Oracle driver and double-check that there are no traces left behind in registry or folders.
3. Reboot the machine
4. (Re)Install the Oracle drivers and re-enable IIS and other auto-start apps.
5. Reboot the machine <- This is vital. Oracle's OLE DB drivers won't work unless you reboot the machine.

If this doesn't work then rinse repeat until the OLE DB drivers work. Hope this helps someone out there struggling to figure out what's going on.

You may go with this way: ( a general example )

insert into QualityAssuranceDB.dbo.Customers (columnA, ColumnB)
Select columnA, columnB from DeveloperDB.dbo.Customers

Also if you need to generate the column names as well to put in insert clause, use:

    select (name + ',') as TableColumns from sys.columns 
where object_id = object_id('YourTableName')

Copy the result and paste into query window to represent your table column names and even this will exclude the identity column as well:

    select (name + ',') as TableColumns from sys.columns 
where object_id = object_id('YourTableName') and is_identity = 0

Remember the script to copy rows will work if the databases belongs to the same location.

You can Try This.

select * into <Destination_table> from <Servername>.<DatabaseName>.dbo.<sourceTable>

Server name is optional if both DB is in same server.

Try this out. After going through a lot of posts and forums, I found this.

mWebView.setDownloadListener(new DownloadListener() {       

    @Override
    public void onDownloadStart(String url, String userAgent,
                                    String contentDisposition, String mimetype,
                                    long contentLength) {
            DownloadManager.Request request = new DownloadManager.Request(
                    Uri.parse(url));

            request.allowScanningByMediaScanner();
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //Notify client once download is completed!
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "Name of your downloadble file goes here, example: Mathematics II ");
            DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
            dm.enqueue(request);
            Toast.makeText(getApplicationContext(), "Downloading File", //To notify the Client that the file is being downloaded
                    Toast.LENGTH_LONG).show();

        }
    });

Do not forget to give this permission! This is very important! Add this in your Manifest file(The AndroidManifest.xml file)

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />        <!-- for your file, say a pdf to work -->

Hope this helps. Cheers :)

A LinkedList can be used as a Queue - but you need to use it right. Here is an example code :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.add(1);
    queue.add(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

1
2

Remember, if you use push instead of add ( which you will very likely do intuitively ), this will add element at the front of the list, making it behave like a stack.

So this is a Queue only if used in conjunction with add.

Try this :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.push(1);
    queue.push(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

2
1

You fiddle already does the job ... maybe you try to get the string before the double colon? (you really should edit your question) Then the code would go like this:

str.substring(0, str.indexOf(":"));

Where 'str' represents the variable with your string inside.

Click here for JSFiddle Example

Javascript

var input_string = document.getElementById('my-input').innerText;
var output_element = document.getElementById('my-output');

var left_text = input_string.substring(0, input_string.indexOf(":"));

output_element.innerText = left_text;

Html

<p>
  <h5>Input:</h5>
  <strong id="my-input">Left Text:Right Text</strong>
  <h5>Output:</h5>
  <strong id="my-output">XXX</strong>
</p>

CSS

body { font-family: Calibri, sans-serif; color:#555; }
h5 { margin-bottom: 0.8em; }
strong {
  width:90%;
  padding: 0.5em 1em;
  background-color: cyan;
}
#my-output { background-color: gold; }

I needed something to call scripts with named parameters. We have a policy of not using ordinal positioning of parameters and requiring the parameter name.

My approach is similar to the ones above but gets the content of the script file that you want to call and sends a parameter block containing the parameters and values.

One of the advantages of this is that you can optionally choose which parameters to send to the script file allowing for non-mandatory parameters with defaults.

Assuming there is a script called "MyScript.ps1" in the temporary path that has the following parameter block:

[CmdletBinding(PositionalBinding = $False)]
param
(
    [Parameter(Mandatory = $True)] [String] $MyNamedParameter1,
    [Parameter(Mandatory = $True)] [String] $MyNamedParameter2,
    [Parameter(Mandatory = $False)] [String] $MyNamedParameter3 = "some default value"
)

This is how I would call this script from another script:

$params = @{
    MyNamedParameter1 = $SomeValue
    MyNamedParameter2 = $SomeOtherValue
}

If ($SomeCondition)
{
    $params['MyNamedParameter3'] = $YetAnotherValue
}

$pathToScript = Join-Path -Path $env:Temp -ChildPath MyScript.ps1

$sb = [scriptblock]::create(".{$(Get-Content -Path $pathToScript -Raw)} $(&{
        $args
} @params)")
Invoke-Command -ScriptBlock $sb

I have used this in lots of scenarios and it works really well. One thing that you occasionally need to do is put quotes around the parameter value assignment block. This is always the case when there are spaces in the value.

e.g. This param block is used to call a script that copies various modules into the standard location used by PowerShell C:\Program Files\WindowsPowerShell\Modules which contains a space character.

$params = @{
        SourcePath      = "$WorkingDirectory\Modules"
        DestinationPath = "'$(Join-Path -Path $([System.Environment]::GetFolderPath('ProgramFiles')) -ChildPath 'WindowsPowershell\Modules')'"
    }

Hope this helps!

Thanks you all! Now it's work. DATAJPA-231

It will be nice if was possible to create count…By… methods just like find…By ones. Example:

public interface UserRepository extends JpaRepository<User, Long> {

   public Long /*or BigInteger */ countByActiveTrue();
}

The best way to do this is disable it with webserver apache2. In my Ubuntu 14.X - open /etc/apache2/apache2.conf change from

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>
        Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

then restart apache by:

sudo service apache2 reload

This will disable directory listing from all folder that apache2 serves.

Running composer dump-autoload solves it for me.

they are some needs i can't see to dome thing like Keith or Marcos Placona did instead of just doing

            //by the way
            //button1.PerformClick();

As a quick and dirty solution leveraging existing infrastructure, you can wrap your uglyPrintedMap into a java.util.HashMap, then use toString().

uglyPrintedMap.toString(); // ugly
System.out.println( uglyPrintedMap ); // prints in an ugly manner

new HashMap<Object, Object>(jobDataMap).toString(); // pretty
System.out.println( new HashMap<Object, Object>(uglyPrintedMap) ); // prints in a pretty manner

I've had the same issue in a VB6 program I'm writing, where a Form uses a ScriptControl object to run VBScripts selected by the User.

It worked fine until the other day, when it suddenly started displaying 'Runtime error 429' when the VBScript attempted to create a Scripting.FileSystemObject.

After going mad for an entire day, trying all the solutions proposed here, I began suspecting the problem was in my application.

Fortunately, I had a backup version of that form: I compared their codes, and discovered that inadvertently I had set UseSafeSubset property of my ScriptControl object to True.

It was the only difference in the form, and after restoring the backup copy it worked like a charm.

Hope this can be useful to someone. Up with VB6! :-)

Okay, I have refined my regular expression based on the solution you came up with (which erroneously matches strings that start with 'test').

^((?!foo).)*$

This regular expression will match only strings that do not contain foo. The first lookahead will deny strings beginning with 'foo', and the second will make sure that foo isn't found elsewhere in the string.

Open port 9418 on your firewall - it's a custom port that Git uses to communicate on and it's often not open on a corporate or private firewall.

I think this is enough to get you on a nice path:

Sub a()
  Dim btn As Button
  Application.ScreenUpdating = False
  ActiveSheet.Buttons.Delete
  Dim t As Range
  For i = 2 To 6 Step 2
    Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
    Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
    With btn
      .OnAction = "btnS"
      .Caption = "Btn " & i
      .Name = "Btn" & i
    End With
  Next i
  Application.ScreenUpdating = True
End Sub

Sub btnS()
 MsgBox Application.Caller
End Sub

It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.

result = initial number + (6 - initial number % 6)

The IntelliJ debugger has a very handy feature called "Evaluate Expression", that is by far better than eclipses pendant. It has full code-completion and i concider it to be generally "more useful".

Add this Annotation to Entity Class (Model) that works for me this cause lazy loading via the hibernate proxy object.

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

It's pretty hard to say definitively without seeing what the rendered html looks like and what styles are being applied to the elements within the treeview div, but the thing that jumps out at me right away is the

overflow-x: scroll;

What happens if you remove that?

This should work fine:

Dim result As DialogResult = MessageBox.Show("message", "caption", MessageBoxButtons.YesNoCancel)
If result = DialogResult.Cancel Then
    MessageBox.Show("Cancel pressed")
ElseIf result = DialogResult.No Then
    MessageBox.Show("No pressed")
ElseIf result = DialogResult.Yes Then
    MessageBox.Show("Yes pressed")
End If

public class matrixcecil {
    public static void main(String args[]){
        List<Integer> k1=new ArrayList<Integer>(10);
        k1.add(23);
        k1.add(10);
        k1.add(20);
        k1.add(24);
        int i=0;
        while(k1.size()<10){
            if(i==(k1.get(k1.size()-1))){

            }
             i=k1.get(k1.size()-1);
             k1.add(30);
             i++;
             break;
        }
        System.out.println(k1);
    }

}

I think this example will help you for better solution.

If you don't call the favicon, favicon.ico, you can use that tag to specify the actual path (incase you have it in an images/ directory). The browser/webpage looks for favicon.ico in the root directory by default.

Using a getter method is a better design choice for a long-lived class as it allows you to replace the getter method with something more complicated in the future. Although this seems less likely to be needed for a const value, the cost is low and the possible benefits are large.

As an aside, in C++, it's an especially good idea to give both the getter and setter for a member the same name, since in the future you can then actually change the the pair of methods:

class Foo {
public:
    std::string const& name() const;          // Getter
    void name(std::string const& newName);    // Setter
    ...
};

Into a single, public member variable that defines an operator()() for each:

// This class encapsulates a fancier type of name
class fancy_name {
public:
    // Getter
    std::string const& operator()() const {
        return _compute_fancy_name();    // Does some internal work
    }

    // Setter
    void operator()(std::string const& newName) {
        _set_fancy_name(newName);        // Does some internal work
    }
    ...
};

class Foo {
public:
    fancy_name name;
    ...
};

The client code will need to be recompiled of course, but no syntax changes are required! Obviously, this transformation works just as well for const values, in which only a getter is needed.

If you have an array of a known type or is a subclass of Object[] you can cast the array first.

Object array = new ????[n];
Object[] array2 = (Object[]) array;
System.out.println(array2.length);

or

Object array = new char[n];
char[] array2 = (char[]) array;
System.out.println(array2.length);

However if you have no idea what type of array it is you can use Array.getLength(Object);

In my case, I was missing import UIKit on top of my NSManagedObject subclass. After importing it, I could remove that error as UIApplication is the part of UIKit

Hope it helps others !!!

You can use like this...

<div id="rot">hello</div>

#rot
{
   -webkit-transform: rotate(-90deg); 
   -moz-transform: rotate(-90deg);    
    width:100px;
}

The Splatting Operator

To create an array, we create a variable and assign the array. Arrays are noted by the "@" symbol. Let's take the discussion above and use an array to connect to multiple remote computers:

$strComputers = @("Server1", "Server2", "Server3")<enter>

They are used for arrays and hashes.

PowerShell Tutorial 7: Accumulate, Recall, and Modify Data

Array Literals In PowerShell

It is also worth to mention, that if you DO NOT intent to modify the values of the list, it is possible (and better) to use the const_iterator, as follows:

for (std::list<Student>::const_iterator it = data.begin(); it != data.end(); ++it){
    // do whatever you wish but don't modify the list elements
    std::cout << it->name;
}

If elem.find() is not working for you, check that you are including JQuery script before angular script....

Fast, simple, but maybe not always right:

>>> [x for x in mylist if x.isdigit()]
['1', '2', '3', '4']

More traditional if you need to get numbers:

new_list = []
for value in mylist:
    try:
        new_list.append(int(value))
    except ValueError:
        continue

Note: The result has integers. Convert them back to strings if needed, replacing the lines above with:

try:
    new_list.append(str(int(value)))

Don't forget DataFrame.tail! e.g. df1.tail(10)

Better one line solution:

var answerInt = [];
var answerString = "1 2 3 4";
answerString.split(' ').forEach(function (item) {
   answerInt.push(parseInt(item))
});

i have this error using datatables.net

i fixed changing the default ajax Get to POST in te properties of the DataTable()

"ajax": {
        "url": "../ControllerName/MethodJson",
        "type": "POST"
    },

Here is what I use.

Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

I would suggest using a drop down menu for each field, making sure to label each as day, month and year. A date picker might also help, but if the user doesn't have JavaScript enabled, it won't work.

You can use scalar multiplication to modify each element in your vector.

> r <- 0:10 
> r <- r * 2
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

or

> r <- 0:10 * 2 
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

You want options(warn=-1). However, note that warn=0 is not the safest warning level and it should not be assumed as the current one, particularly within scripts or functions. Thus the safest way to temporary turn off warnings is:

oldw <- getOption("warn")
options(warn = -1)

[your "silenced" code]

options(warn = oldw)

Framebuffer seems the way to go, it will not always contain 2+ frames like mentioned by Ryan Conrad. In my case it contained only one. I guess it depends on the frame/display size.

I tried to read the framebuffer continuously but it seems to return for a fixed amount of bytes read. In my case that is (3 410 432) bytes, which is enough to store a display frame of 854*480 RGBA (3 279 360 bytes). Yes, the frame in binary outputed from fb0 is RGBA in my device. This will most likely depend from device to device. This will be important for you to decode it =)

In my device /dev/graphics/fb0 permissions are so that only root and users from group graphics can read the fb0. graphics is a restricted group so you will probably only access fb0 with a rooted phone using su command.

Android apps have the user id (uid) app_## and group id (guid) app_## .

adb shell has uid shell and guid shell, which has much more permissions than an app. You can actually check those permissions at /system/permissions/platform.xml

This means you will be able to read fb0 in the adb shell without root but you will not read it within the app without root.

Also, giving READ_FRAME_BUFFER and/or ACCESS_SURFACE_FLINGER permissions on AndroidManifest.xml will do nothing for a regular app because these will only work for 'signature' apps.

There are three main approaches:

String email = /* Your email address here */
String subject = /* Your subject here */
String body = /* Your body here */
String chooserTitle = /* Your chooser title here */

1. Custom Uri:

Uri uri = Uri.parse("mailto:" + email)
    .buildUpon()
    .appendQueryParameter("subject", subject)
    .appendQueryParameter("body", body)
    .build();

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(Intent.createChooser(emailIntent, chooserTitle));

2. Using Intent extras:

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + email));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
//emailIntent.putExtra(Intent.EXTRA_HTML_TEXT, body); //If you are using HTML in your body text

startActivity(Intent.createChooser(emailIntent, "Chooser Title"));

3. Support Library ShareCompat:

Activity activity = /* Your activity here */

ShareCompat.IntentBuilder.from(activity)
    .setType("message/rfc822")
    .addEmailTo(email)
    .setSubject(subject)
    .setText(body)
    //.setHtmlText(body) //If you are using HTML in your body text
    .setChooserTitle(chooserTitle)
    .startChooser();

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

It also matters the order of the dependencies. I've had the same issue. And basically I had to put first the scope test and then scope compile dependencies in the pom.xml. If I put first the scope compile and then the scope test it will fail.

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKCYAN = '\033[96m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

def colour_print(text,colour):
    if colour == 'OKBLUE':
        string = bcolors.OKBLUE + text + bcolors.ENDC
        print(string)
    elif colour == 'HEADER':
        string = bcolors.HEADER + text + bcolors.ENDC
        print(string)
    elif colour == 'OKCYAN':
        string = bcolors.OKCYAN + text + bcolors.ENDC
        print(string)
    elif colour == 'OKGREEN':
        string = bcolors.OKGREEN + text + bcolors.ENDC
        print(string)
    elif colour == 'WARNING':
        string = bcolors.WARNING + text + bcolors.ENDC
        print(string)
    elif colour == 'FAIL':
        string = bcolors.HEADER + text + bcolors.ENDC
        print(string)
    elif colour == 'BOLD':
        string = bcolors.BOLD + text + bcolors.ENDC
        print(string)
    elif colour == 'UNDERLINE':
        string = bcolors.UNDERLINE + text + bcolors.ENDC
        print(string)

just copy the above code. just call them easily

colour_print('Hello world','OKBLUE')
colour_print('easy one','OKCYAN')
colour_print('copy and paste','OKGREEN')
colour_print('done','OKBLUE')

Hope it would help

It depends on what string type you're talking about. There are many types of strings:

1. const char* - a C-style multibyte string
2. const wchar_t* - a C-style wide string
3. std::string - a "standard" multibyte string
4. std::wstring - a "standard" wide string

For 3 and 4, you can use .size() or .length() methods.

For 1, you can use strlen(), but you must ensure that the string variable is not NULL (=== 0)

For 2, you can use wcslen(), but you must ensure that the string variable is not NULL (=== 0)

There are other string types in non-standard C++ libraries, such as MFC's CString, ATL's CComBSTR, ACE's ACE_CString, and so on, with methods such as .GetLength(), and so on. I can't remember the specifics of them all right off the top of my head.

The STLSoft libraries have abstracted this all out with what they call string access shims, which can be used to get the string length (and other aspects) from any type. So for all of the above (including the non-standard library ones) using the same function stlsoft::c_str_len(). This article describes how it all works, as it's not all entirely obvious or easy.

It's all in your things.size() type. It isn't int, but size_t (it exists in C++, not in C) which equals to some "usual" unsigned type, i.e. unsigned int for x86_32.

Operator "less" (<) cannot be applied to two operands of different sign. There's just no such opcodes, and standard doesn't specify, whether compiler can make implicit sign conversion. So it just treats signed number as unsigned and emits that warning.

It would be correct to write it like

for (size_t i = 0; i < things.size(); ++i) { /**/ }

or even faster

for (size_t i = 0, ilen = things.size(); i < ilen; ++i) { /**/ }

A solution without reference to a Bean:

<h:button value="login" 
        outcome="content/configuration.xhtml?i=1" />

In my project I needed this approach:

<h:commandButton value="login" 
        action="content/configuration.xhtml?faces-redirect=true&amp;i=1"  />

public String getLocalIpAddress() {

    try {
        for (Enumeration < NetworkInterface > en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = en.nextElement();
            for (Enumeration < InetAddress > enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress()) {
                    return inetAddress.getHostAddress().toString();
                }
            }
        }
    } catch (SocketException ex) {
        Log.e(LOG_TAG, ex.toString());
    }
    return null;
}

I used this line command to search ".xlm" files in "C:\Temp" and the result print fullname path in file "result.txt":

(Get-ChildItem "C:\Temp" -Recurse | where {$_.extension -eq ".xml"} ).fullname > result.txt 

In my tests, this syntax works beautiful for me.

Your confusion stems from the fact that declared properties are not (necessarily named the same as) (instance) variables.

The expresion

indexPath.row

is equivalent to

[indexPath row]

and the assignment

delegate.myData = [myData objectAtIndex:indexPath.row];

is equivalent to

[delegate setMyData:[myData objectAtIndex:[indexPath row]]];

assuming standard naming for synthesised properties.

Furthermore, delegate is probably declared as being of type id<SomeProtocol>, i.e., the compiler hasn’t been able to provide actual type information for delegate at that point, and the debugger is relying on information provided at compile-time. Since id is a generic type, there’s no compile-time information about the instance variables in delegate.

Those are the reasons why you don’t see myData or row as variables.

If you want to inspect the result of sending -row or -myData, you can use commands p or po:

p (NSInteger)[indexPath row]
po [delegate myData]

or use the expressions window (for instance, if you know your delegate is of actual type MyClass *, you can add an expression (MyClass *)delegate, or right-click delegate, choose View Value as… and type the actual type of delegate (e.g. MyClass *).

That being said, I agree that the debugger could be more helpful:

• There could be an option to tell the debugger window to use run-time type information instead of compile-time information. It'd slow down the debugger, granted, but would provide useful information;

• Declared properties could be shown up in a group called properties and allow for (optional) inspection directly in the debugger window. This would also slow down the debugger because of the need to send a message/execute a method in order to get information, but would provide useful information, too.

@GET
@Path("/friends")
@Produces(MediaType.APPLICATION_JSON)
public String getFriends() {

    // here you can return any bean also it will automatically convert into json 
    return "{'friends': ['Michael', 'Tom', 'Daniel', 'John', 'Nick']}";
}

I was also strugling with this issue and the answer is way easier than those provided over here. you can just look for it using xpath and unset it it the following method:

unset($XML->xpath("NODESNAME[@id='test']")[0]->{0});

this code will look for a node named "NODESNAME" with the id attribute "test" and remove the first occurence.

remember to save the xml using $XML->saveXML(...);

The questions is perfectly valid and clear since Spinner and ComboBox (read it: Spinner where you can provide a custom value as well) are two different things.

I was looking for the same thing myself and I wasn't satisfied with the given answers. So I created my own thing. Perhaps some will find the following hints useful. I am not providing the full source code as I am using some legacy calls in my own project. It should be pretty clear anyway.

Here is the screenshot of the final thing:

The first thing was to create a view that will look the same as the spinner that hasn't been expanded yet. In the screenshot, on the top of the screen (out of focus) you can see the spinner and the custom view right bellow it. For that purpose I used LinearLayout (actually, I inherited from Linear Layout) with style="?android:attr/spinnerStyle". LinearLayout contains TextView with style="?android:attr/spinnerItemStyle". Complete XML snippet would be:

<com.example.comboboxtest.ComboBox 
    style="?android:attr/spinnerStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <TextView
        android:id="@+id/textView"
        style="?android:attr/spinnerItemStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:singleLine="true"
        android:text="January"
        android:textAlignment="inherit" 
    />

</com.example.comboboxtest.ComboBox>

As, I mentioned earlier ComboBox inherits from LinearLayout. It also implements OnClickListener which creates a dialog with a custom view inflated from the XML file. Here is the inflated view:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" 
    >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" 
        >
        <EditText
            android:id="@+id/editText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ems="10"
            android:hint="Enter custom value ..." >

            <requestFocus />
        </EditText>

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="OK" 
        />
    </LinearLayout>

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
    />

</LinearLayout>

There are two more listeners that you need to implement: onItemClick for the list and onClick for the button. Both of these set the selected value and dismiss the dialog.

For the list, you want it to look the same as expanded Spinner, you can do that providing the list adapter with the appropriate (Spinner) style like this:

ArrayAdapter<String> adapter = 
    new ArrayAdapter<String>(
        activity,
        android.R.layout.simple_spinner_dropdown_item, 
        states
    );

More or less, that should be it.

I had a slightly more specialised case, a search form which had an input which had autocomplete for a person name. The Javascript code set a hidden input which from.reset() does not clear.

However I didn't want to reset all hidden inputs. There I added a class, search-value, to the hidden inputs which where to be cleared.

$('form#search-form').reset();
$('form#search-form input[type=hidden].search-value').val('');

Try MySQL Workbench, formerly DBDesigner 4:

http://dev.mysql.com/workbench/

This has a "Reverse Engineer Database" mode:

Database -> Reverse Engineer

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

it's also possible to create a unique constraint of more than 1 column:

ALTER TABLE the_table 
    ADD CONSTRAINT constraint_name UNIQUE (column1, column2);

Though my response is late, but it can still help.

lf you are using Spring Tool Suite and you still think that the JQuery file reference path is correct, then refresh your project whenever you modify the JQuery file.

You refresh by right-clicking on the project name -> refresh.

That's what solved mine.

For Windows users

I usually upgrade Yarn with Chocolatey.

choco upgrade yarn

I could not resolve this with CSS. It seems like Boostrap is getting the last say even though I have by site.css after bootstrap. In any event, this worked for me.

$(document).ready(function () {
    var elements = document.getElementsByClassName("form-control");

    Array.from(elements).forEach(function () {
        this.addEventListener("click", cbChange, false);
    })

    });

function cbChange(event) {
    var ele = event.target;
    var obj = document.getElementById(ele.id);
    obj.style.borderColor = "lightgrey";
}

Later I found this to work in the css. Obviously with form-controls only

.form-control.focus, .form-control:focus {
    border-color: gainsboro;
} 

Here are before and after shots from Chrome Developer tool. Notice the difference in border color between focus on and focus off. On a side note, this does not work for buttons. With buttons. With buttons you have to change outline property to none.

Console.ReadKey(true);

This command is a bit nicer than readline which passes only when you hit enter, and the true parameter also hides the ugly flashing cursor while reading the result :) then any keystroke terminates

I'm using this variant for force print K decimal places:

# format numeric value to K decimal places
formatDecimal <- function(x, k) format(round(x, k), trim=T, nsmall=k)

<button onclick="location.href='@Url.Action("NewCustomer", "Customers")'">Checkout >></button>

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

>>> class Foo():
...     def bar(self, bar, **kwargs):
...             print(bar)
... 
>>> kwgs = {"bar":"Barred", "jokes":"Another key word argument"}
>>> myfoo = Foo()
>>> myfoo.bar("fire", **kwgs)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: bar() got multiple values for argument 'bar'
>>> 

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

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

I've found that using this null comparison works well:

if (Combobox.SelectedItem != null){
   //Do something
}
else{
  MessageBox.show("Please select a item");
}

This will only accept the selected item and no other value which may have been entered manually by the user which could cause validation issues.

In PHPMailer.php, there are lines as below:

echo $e->getMessage()

Just comment these lines and you will be good to go.

printf("%.12f", M_PI);

%.12f means floating point, with precision of 12 digits.

You can create a new model to Deserialize your Json CustomerJson:

public class CustomerJson
{
    [JsonProperty("customer")]
    public Customer Customer { get; set; }
}

public class Customer
{
    [JsonProperty("first_name")]
    public string Firstname { get; set; }

    [JsonProperty("last_name")]
    public string Lastname { get; set; }

    ...
}

And you can deserialize your json easily :

JsonConvert.DeserializeObject<List<CustomerJson>>(json);

Hope it helps !

Look at the following example, from the HTML5 specification about aside.

It makes clear that what currently is recommended (October 2012) it is to group widgets inside aside elements. Then, each widget is whatever best represents it, a nav, a serie of blockquotes, etc

The following extract shows how aside can be used for blogrolls and other side content on a blog:

<body>
 <header>
  <h1>My wonderful blog</h1>
  <p>My tagline</p>
 </header>
 <aside>
  <!-- this aside contains two sections that are tangentially related
  to the page, namely, links to other blogs, and links to blog posts
  from this blog -->
  <nav>
   <h1>My blogroll</h1>
   <ul>
    <li><a href="http://blog.example.com/">Example Blog</a>
   </ul>
  </nav>
  <nav>
   <h1>Archives</h1>
   <ol reversed>

I had a similar issue, and following previous answers (thanks!), I was able to search and find how to handle correctly the ThreadPoolExecutor terminaison.

In my case, that just fix my progressive increase of similar blocked threads:

• I've used ExecutorService::awaitTermination(x, TimeUnit) and ExecutorService::shutdownNow() (if necessary) in my finally clause.

• For information, I've used the following commands to detect thread count & list locked threads:

  ps -u javaAppuser -L|wc -l

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayA.log

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayAPlusOne.log

  cat threadPrint*.log |grep "pool-"|wc -l

Use JpaRepository or CrudRepository as repository interface:

@Repository
public interface CustomerRepository extends JpaRepository<Customer, Integer> {

    @Query("SELECT t from Customer t where LOWER(t.name) LIKE %:name%")
    public List<Customer> findByName(@Param("name") String name);

}


@Service(value="customerService")
public class CustomerServiceImpl implements CustomerService {

    private CustomerRepository customerRepository;
    
    //...

    @Override
    public List<Customer> pattern(String text) throws Exception {
        return customerRepository.findByName(text.toLowerCase());
    }
}

You need ReDim:

m = 5
n = 8
Dim my_array()
ReDim my_array(1 To m, 1 To n)
For i = 1 To m
  For j = 1 To n
    my_array(i, j) = i * j
  Next
Next

For i = 1 To m
  For j = 1 To n
    Cells(i, j) = my_array(i, j)
  Next
Next

As others have pointed out, your actual problem would be better solved with ranges. You could try something like this:

Dim r1 As Range
Dim r2 As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet

Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
totalRow = ws1.Range("A1").End(xlDown).Row
totalCol = ws1.Range("A1").End(xlToRight).Column

Set r1 = ws1.Range(ws1.Cells(1, 1), ws1.Cells(totalRow, totalCol))
Set r2 = ws2.Range(ws2.Cells(1, 1), ws2.Cells(totalRow, totalCol))
r2.Value = r1.Value

This may Help you ! ....

Uninstalling pycparser:

pip uninstall pycparser

Reinstall pycparser:

pip install pycparser

I got same error while installing termcolor and I fixed it by reinstalling it .

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments["<host>"], arguments["<port>"])

I use to just create it without parameters, and then edit the registry HKLM\System\CurrentControlSet\Services\[YourService].

nothing to be done for running your wamp sites to another computer. 1. first turn off the firewall. 2. Set Put Online in wamp by clcking in wamp icon at near to clock.

Finally run your browser in another computer and type http:\ip address or computer name e.g. http:\192.168.1.100

^https?://

You might have to escape the forward slashes though, depending on context.

tl;dr

LocalTime.parse( "10:30" )  // Parsed as 24-hour time.

java.time

Avoid the troublesome old date-time classes such as Date and Calendar that are now supplanted by the java.time classes.

LocalTime

The java.time classes provide a way to represent the time-of-day without a date and without a time zone: LocalTime

LocalTime lt = LocalTime.of( 10 , 30 );  // 10:30 AM.
LocalTime lt = LocalTime.of( 22 , 30 );  // 22:30 is 10:30 PM.

ISO 8601

The java.time classes use standard ISO 8601 formats by default when generating and parsing strings. These formats use 24-hour time.

String output = lt.toString();

LocalTime.of( 10 , 30 ).toString() : 10:30

LocalTime.of( 22 , 30 ).toString() : 22:30

So parsing 10:30 will be interpreted as 10:30 AM.

LocalTime lt = LocalTime.parse( "10:30" );  // 10:30 AM.

DateTimeFormatter

If you need to generate or parse strings in 12-hour click format with AM/PM, use the DateTimeFormatter class. Tip: make a habit of specifying a Locale.

How to prevent php form resubmission without redirect. If you are using $_SESSION (after session_start) and a $_POST form, you can do something like this:

if ( !empty($_SESSION['act']) && !empty($_POST['act']) && $_POST['act'] == $_SESSION['act'] ) {
  // do your stuff, save data into database, etc
}

In your html form put this:

<input type="hidden" id="act" name="act" value="<?php echo ( empty($_POST['act']) || $_POST['act']==2 )? 1 : 2; ?>">
<?php
if ( $_POST['act'] == $_SESSION['act'] ){
    if ( empty( $_SESSION['act'] ) || $_SESSION['act'] == 2 ){
        $_SESSION['act'] = 1;
    } else {
        $_SESSION['act'] = 2;
    }
}
?>

So, every time when the form is submitted, a new act is generated, stored in session and compared with the post act.

Ps: if you are using an Get form, you can easily change all POST with GET and it works too.

If you're using at least Java 8, see my other answer.

If you're already using Google Guava, see Sean Patrick Floyd's answer.

If you're stuck at Java 7 and don't want to include Google Guava, you can write your own (read-only) Iterables.concat() using no more than Iterable and Iterator:

Constant number

public static <E> Iterable<E> concat(final Iterable<? extends E> iterable1,
                                     final Iterable<? extends E> iterable2) {
    return new Iterable<E>() {
        @Override
        public Iterator<E> iterator() {
            return new Iterator<E>() {
                final Iterator<? extends E> iterator1 = iterable1.iterator();
                final Iterator<? extends E> iterator2 = iterable2.iterator();

                @Override
                public boolean hasNext() {
                    return iterator1.hasNext() || iterator2.hasNext();
                }

                @Override
                public E next() {
                    return iterator1.hasNext() ? iterator1.next() : iterator2.next();
                }
            };
        }
    };
}

Variable number

@SafeVarargs
public static <E> Iterable<E> concat(final Iterable<? extends E>... iterables) {
    return concat(Arrays.asList(iterables));
}

public static <E> Iterable<E> concat(final Iterable<Iterable<? extends E>> iterables) {
    return new Iterable<E>() {
        final Iterator<Iterable<? extends E>> iterablesIterator = iterables.iterator();

        @Override
        public Iterator<E> iterator() {
            return !iterablesIterator.hasNext() ? Collections.emptyIterator()
                                                : new Iterator<E>() {
                Iterator<? extends E> iterableIterator = nextIterator();

                @Override
                public boolean hasNext() {
                    return iterableIterator.hasNext();
                }

                @Override
                public E next() {
                    final E next = iterableIterator.next();
                    findNext();
                    return next;
                }

                Iterator<? extends E> nextIterator() {
                    return iterablesIterator.next().iterator();
                }

                Iterator<E> findNext() {
                    while (!iterableIterator.hasNext()) {
                        if (!iterablesIterator.hasNext()) {
                            break;
                        }
                        iterableIterator = nextIterator();
                    }
                    return this;
                }
            }.findNext();
        }
    };
}

I feel that the overall answer does not handle if the dates 'wrap' around a year. This would be useful in understanding proximity to a date being accurate by day of year. In order to do these row operations, I did the following. (I had this used in a business setting in renewing customer subscriptions).

def get_date_difference(row, x, y):
    try:
        # Calcuating the smallest date difference between the start and the close date
        # There's some tricky logic in here to calculate for determining date difference
        # the other way around (Dec -> Jan is 1 month rather than 11)

        sub_start_date = int(row[x].strftime('%j')) # day of year (1-366)
        close_date = int(row[y].strftime('%j')) # day of year (1-366)

        later_date_of_year = max(sub_start_date, close_date) 
        earlier_date_of_year = min(sub_start_date, close_date)
        days_diff = later_date_of_year - earlier_date_of_year

# Calculates the difference going across the next year (December -> Jan)
        days_diff_reversed = (365 - later_date_of_year) + earlier_date_of_year
        return min(days_diff, days_diff_reversed)

    except ValueError:
        return None

Then the function could be:

dfAC_Renew['date_difference'] = dfAC_Renew.apply(get_date_difference, x = 'customer_since_date', y = 'renewal_date', axis = 1)

To ignore some folder from eslint rules we could create the file .eslintignore in root directory and add there the path to the folder we want omit (the same way as for .gitignore).

Here is the example from the ESLint docs on Ignoring Files and Directories:

# path/to/project/root/.eslintignore
# /node_modules/* and /bower_components/* in the project root are ignored by default

# Ignore built files except build/index.js
build/*
!build/index.js

Go to the start menu. Open up cmd (command prompt) and type in the following.

wmic process list brief | find /i "tomcat"

This would tell you if the tomcat is running or not.

There is actually a default pattern that you can employ to achieve this result without having to implement IDesignTimeDbContextFactory and do any config file copying.

It is detailed in this doc, which also discusses the other ways in which the framework will attempt to instantiate your DbContext at design time.

Specifically, you leverage a new hook, in this case a static method of the form public static IWebHost BuildWebHost(string[] args). The documentation implies otherwise, but this method can live in whichever class houses your entry point (see src). Implementing this is part of the guidance in the 1.x to 2.x migration document and what's not completely obvious looking at the code is that the call to WebHost.CreateDefaultBuilder(args) is, among other things, connecting your configuration in the default pattern that new projects start with. That's all you need to get the configuration to be used by the design time services like migrations.

Here's more detail on what's going on deep down in there:

While adding a migration, when the framework attempts to create your DbContext, it first adds any IDesignTimeDbContextFactory implementations it finds to a collection of factory methods that can be used to create your context, then it gets your configured services via the static hook discussed earlier and looks for any context types registered with a DbContextOptions (which happens in your Startup.ConfigureServices when you use AddDbContext or AddDbContextPool) and adds those factories. Finally, it looks through the assembly for any DbContext derived classes and creates a factory method that just calls Activator.CreateInstance as a final hail mary.

The order of precedence that the framework uses is the same as above. Thus, if you have IDesignTimeDbContextFactory implemented, it will override the hook mentioned above. For most common scenarios though, you won't need IDesignTimeDbContextFactory.

Two important pitfalls

which were ignored by other answers so far:

1. Trailing newline removal from command expansion
2. NUL character removal

Trailing newline removal from command expansion

This is a problem for the:

value="$(cat config.txt)"

type solutions, but not for read based solutions.

Command expansion removes trailing newlines:

S="$(printf "a\n")"
printf "$S" | od -tx1

Outputs:

0000000 61
0000001

This breaks the naive method of reading from files:

FILE="$(mktemp)"
printf "a\n\n" > "$FILE"
S="$(<"$FILE")"
printf "$S" | od -tx1
rm "$FILE"

POSIX workaround: append an extra char to the command expansion and remove it later:

S="$(cat $FILE; printf a)"
S="${S%a}"
printf "$S" | od -tx1

Outputs:

0000000 61 0a 0a
0000003

Almost POSIX workaround: ASCII encode. See below.

NUL character removal

There is no sane Bash way to store NUL characters in variables.

This affects both expansion and read solutions, and I don't know any good workaround for it.

Example:

printf "a\0b" | od -tx1
S="$(printf "a\0b")"
printf "$S" | od -tx1

Outputs:

0000000 61 00 62
0000003

0000000 61 62
0000002

Ha, our NUL is gone!

Workarounds:

• ASCII encode. See below.

• use bash extension $"" literals:

  S=$"a\0b"
  printf "$S" | od -tx1
  

  Only works for literals, so not useful for reading from files.

Workaround for the pitfalls

Store an uuencode base64 encoded version of the file in the variable, and decode before every usage:

FILE="$(mktemp)"
printf "a\0\n" > "$FILE"
S="$(uuencode -m "$FILE" /dev/stdout)"
uudecode -o /dev/stdout <(printf "$S") | od -tx1
rm "$FILE"

Output:

0000000 61 00 0a
0000003

uuencode and udecode are POSIX 7 but not in Ubuntu 12.04 by default (sharutils package)... I don't see a POSIX 7 alternative for the bash process <() substitution extension except writing to another file...

Of course, this is slow and inconvenient, so I guess the real answer is: don't use Bash if the input file may contain NUL characters.

We can also set the vertical alignment with using this way

$style_cell = array(
   'alignment' => array(
       'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
       'vertical' => PHPExcel_Style_Alignment::VERTICAL_CENTER,
   ) 
); 

with this cell set the vertically aligned into the middle.

Try the following :

String url = "http://www.google.com/search?q=java";
URL urlObj = (URL)new URL(url.trim());
HttpURLConnection httpConn = 
(HttpURLConnection)urlObj.openConnection();
httpConn.setRequestMethod("GET");
Integer rescode = httpConn.getResponseCode();
System.out.println(rescode);

Trim() the URL

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter]
     addObserver:self selector:@selector(triggerAction:) name:@"NotificationMessageEvent" object:nil];
}

#pragma mark - Notification
-(void) triggerAction:(NSNotification *) notification
{
    NSDictionary *dict = notification.userInfo;
    YourDataObject *message = [dict valueForKey:@"message"];
    if (message != nil) {
        // do stuff here with your message data
    }
}

check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js

A logging script that I have written some time ago might be of help, although it is not exactly what you want. It acts in a way like a System.out.println but with much more information about StackTrace etc. It also provides Clickable text for Eclipse:

private static final SimpleDateFormat   extended    = new SimpleDateFormat( "dd MMM yyyy (HH:mm:ss) zz" );

public static java.util.logging.Logger initLogger(final String name) {
    final java.util.logging.Logger logger = java.util.logging.Logger.getLogger( name );
    try {

        Handler ch = new ConsoleHandler();
        logger.addHandler( ch );

        logger.setLevel( Level.ALL ); // Level selbst setzen

        logger.setUseParentHandlers( false );

        final java.util.logging.SimpleFormatter formatter = new SimpleFormatter() {

            @Override
            public synchronized String format(final LogRecord record) {
                StackTraceElement[] trace = new Throwable().getStackTrace();
                String clickable = "(" + trace[ 7 ].getFileName() + ":" + trace[ 7 ].getLineNumber() + ") ";
                /* Clickable text in Console. */

                for( int i = 8; i < trace.length; i++ ) {
                    /* 0 - 6 is the logging trace, 7 - x is the trace until log method was called */
                    if( trace[ i ].getFileName() == null )
                        continue;
                    clickable = "(" + trace[ i ].getFileName() + ":" + trace[ i ].getLineNumber() + ") -> " + clickable;
                }

                final String time = "<" + extended.format( new Date( record.getMillis() ) ) + "> ";

                StringBuilder level = new StringBuilder("[" + record.getLevel() + "] ");
                while( level.length() < 15 ) /* extend for tabby display */
                    level.append(" ");

                StringBuilder name = new StringBuilder(record.getLoggerName()).append(": ");
                while( name.length() < 15 ) /* extend for tabby display */
                    name.append(" ");

                String thread = Thread.currentThread().getName();
                if( thread.length() > 18 ) /* trim if too long */
                    thread = thread.substring( 0, 16 ) + "..."; 
                else {
                    StringBuilder sb = new StringBuilder(thread);
                    while( sb.length() < 18 ) /* extend for tabby display */
                        sb.append(" ");
                    thread = sb.insert( 0, "Thread " ).toString();
                }

                final String message = "\"" + record.getMessage() + "\" ";

                return level + time + thread + name + clickable + message + "\n";
            }
        };
        ch.setFormatter( formatter );
        ch.setLevel( Level.ALL );
    } catch( final SecurityException e ) {
        e.printStackTrace();
    }
    return logger;
}

Notice this outputs to the console, you can change that, see http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/Logger.html for more information on that.

Now, the following will probably do what you want. It will go through all causes of a Throwable and save it in a String. Note that this does not use StringBuilder, so you can optimize by changing it.

Throwable e = ...
String detail = e.getClass().getName() + ": " + e.getMessage();
for( final StackTraceElement s : e.getStackTrace() )
    detail += "\n\t" + s.toString();
while( ( e = e.getCause() ) != null ) {
    detail += "\nCaused by: ";
    for( final StackTraceElement s : e.getStackTrace() )
        detail += "\n\t" + s.toString();
}
